m4/ChangeLog
Gary V. Vaughan cceb922d06 Factor load functionality into include builtin. 
* m4/module.c (m4__module_open): Instead of calling lt_dlopenext
right away, use the preload hint first incase path searching has
been disabled by POSIXLY_CORRECT.  Otherwise fallback to a
manual path search to override libltdl's algorithm.
* m4/m4module.h: Adjust.
* m4/path.c (FILE_SUFFIXES): Order to try suffixes in our path
search algorithm.
(NO_SUFFIXES): Alternatively, how to to search a path without
adding file suffixes.
(m4_path_search): Add a new suffixes parameter defaulting to
NO_SUFFIXES.  Adjust all callers.
(m4_load_filename): New generic load function that tries to
open a matched file first as a module, and if that fails fall
back to as (possibly frozen) m4 input.
(m4_fopen): New function with close on exec functionality.
* modules/m4.c (include, sinclude): Use m4_load_filename to
overload these builtins to work with modules too.
* modules/load.c (load): Removed this builtin.
* src/main.c: Remove Dynamic loading features section, and
M4MODPATH support.
(long_options): Remove "load-module", "unload-module" and
"module-directory" options.
(OPTSTRING): Remove 'M' and 'm' options.
(process_file): Use m4_load_filename to support module names
on the command line.
* Makefile.am (TESTS_ENVIRONMENT): No need for abs_top_builddir
any more.
* doc/m4.texinfo: Update examples.
(Dynamic loading features, Load): Removed.
(Command line files): Describe how non-option arguments are
treated to try to find a matching macro file or dso.
(Include): Describe additional dso loading features if a
suitable text file cannot be found.
(Modules): Updated.
* tests/builtins.at, tests/m4.in, tests/modules.at,
tests/options.at: Adjust test cases and calling conventions
to new semantics.
* NEWS: Updated.

2008-04-14 Eric Blake <ebb9@byu.net>
Stage 21b: $@ concatenates builtins, m4wrap takes builtins.
Improve arg_print to handle builtin tokens when printing to a
known chain, rather than always flattening builtins. This allows
m4wrap and $@ back-references to handle embedded builtin tokens.
Memory impact: none.
Speed impact: slight penalty, from more bookkeeping.
* m4/m4module.h (m4_push_builtin): Add parameter.
(m4_builtin_print, m4_push_wrapup_init, m4_push_wrapup_finish)
(m4_arg_print, m4_symbol_value_print): Rename and reduce scope...

* doc/m4.texinfo (M4wrap): New test.
(Debuglen): Adjust expected output.
Stage 21a: Optimize checks for end of input.
Create a new polymorphic input block type, which always fails with
CHAR_EOF, so that remaining input routines no longer have to check
for NULL input block.
Memory impact: none.
Speed impact: noticeable improvement, from fewer conditionals.
* m4/input.c (eof_funcs, input_eof): New objects.
(eof_peek, eof_read, eof_unget): New functions.
(file_clean, m4_push_string_init, pop_input, m4_push_wrapup_init)
(m4_pop_wrapup, next_char, peek_char, unget_input, m4_input_init)
(m4_input_exit): Use placeholder to guarantee non-NULL isp and
wsp.
(next_char): Rename retry to allow_unget, and change sense for
easier manipulation. All callers changed.
Improve OS/2 detection.
* modules/gnu.c (m4_macro_table): Ensure all possible identifiers
are defined, not just the first. The testsuite ensures that
exactly one gets defined.
* m4/system_.h [__EMX__]: OS/2 is not Unix-compatible, no matter
what other pre-defined macros it has.
* THANKS: Update.
Reported by Elbert Pol.
Ensure __m4_version__ is unquoted.
* tests/builtins.at (__m4_@&t@version__): Augment test.
Avoid GNU make failure on tarball.
* Makefile.am (EXTRA_DIST): Distribute cfg.mk and maint.mk.

* m4/utility.c (m4_symbol_value_lookup): Change signature.
* modules/m4.c (undefine, popdef, ifdef, m4_dump_symbols, defn):
Adjust all callers.
* tests/others.at (ifndef): New test.
Be namespace clean for M4 version; fixes 2008-04-08 regression.
* configure.ac (version): Rename...
(M4_VERSION): ...to this, since using 'version' broke po.m4.
2008-04-09 Eric Blake <ebb9@byu.net>

* NEWS: Mention 1.4.11 release.
* tests/builtins.at (divert): Add additional test.
2008-04-08 Eric Blake <ebb9@byu.net>
Overhaul inter-version releases to work with git.

contents when using git 1.5.5+, hardcoded to 1.9a otherwise.
(TIMESTAMP): Delete, since CVS id expansion died with transition
to git.
(AM_INIT_AUTOMAKE): Use version to decide gnu vs. gnits.
* build-aux/mkstamp: Delete, no longer used.
* Makefile.am (CONFIG_STATUS_DEPENDENCIES): Kill, to speed up
rebuilds when timestamps don't matter.
(MKSTAMP): Delete, no longer used.
(EXTRA_DIST): No longer worry about mkstamp.
(.version): New rule and distributed file.
(doc/m4.1, tests/package.m4): Depend on .version, not

* maint.mk: ...into this new file.
2008-03-18 Eric Blake <ebb9@byu.net>
Stage 20b: make m4wrap obey POSIX fifo ordering.
Improve input engine to support location changes within symbol
chains, then convert m4wrap to always build symbol chain.
Memory impact: none.
Speed impact: slight penalty, from more m4wrap bookkeeping.
* m4/m4module.h (m4_wrap_args): Add prototype.
* m4/m4private.h (enum m4__symbol_chain_type): Add M4__CHAIN_LOC.

* tests/builtins.at (wrap): Likewise.
* NEWS: Document this change.
2008-03-17 Eric Blake <ebb9@byu.net>
Stage 20a: reduce unget's in input engine.
Now that out-of-range input placeholders like CHAR_BUILTIN are
consumed outside of next_char, next_token should always consume
rather than peek at the first character. Fewer peeks results in
less ungetc overhead.
Memory impact: none.
Speed impact: noticeable improvement, from fewer function calls.
* m4/input.c (struct input_funcs): Alter read_func prototype.
(next_char, file_read, buildin_read, string_read, composite_read):
Add allow_argv parameter.

(M4wrap): ...here, to match improved example.
2008-03-13 Eric Blake <ebb9@byu.net>
Stage 19c: allow builtin tokens in more macros.
Allow builtin tokens inside symbol chains, although for now, they
are not allowed inside comments or quotes. Enable builtin token
handling in more macros, if only to consistently diagnose invalid
macro names.
Memory impact: none.
Speed impact: slight impact, due to more bookkeeping.
* m4/m4module.h (m4_symbol_value_lookup, m4_builtin_print): New
prototypes.

(composite_peek, composite_read, composite_unget, composite_clean)
(composite_print): Handle builtin tokens.
(init_builtin_token): Allow builtin tokens from composite input.
(m4__next_token): Flatten builtins inside comment or string.
* m4/macro.c (expand_argument): Strengthen assertion.
(collect_arguments, m4_arg_equal, m4_arg_print, m4_push_args):
Handle builtin tokens.
(arg_symbol): Add parameter, and allow NULL level.
(m4_arg_symbol, m4__push_arg_quote): Adjust callers.
(m4_arg_text): Ensure all builtins have been flattened.

(undefine, m4_dump_symbols): Warn on invalid macro names.
(ifdef, ifelse, shift): Handle builtin tokens.
* modules/gnu.c (m4symbols): Likewise.
* doc/m4.texinfo (Defn, Ifdef, Ifelse): Document and test the new
behavior.
(Debuglen): Likewise, and remove xfail.
* NEWS: Mention the change.
Stage 19b: invert sense of bit for handling builtin tokens.
Pass builtin tokens by default, rather than as the exception, so
that the logic can consistently refer to flattening arguments.
Memory impact: none.
Speed impact: none.
* m4/m4module.h (M4BUILTIN_ENTRY): New convenience macro.
(M4_BUILTIN_GROKS_MACRO): Rename...
(M4_BUILTIN_FLATTEN_ARGS): ...and invert sense.
(m4_symbol_value_groks_macro, m4_symbol_groks_macro): Likewise...
(m4_symbol_value_flatten_args, m4_symbol_flatten_args): ...to
this.
* m4/m4private.h (VALUE_MACRO_ARGS_BIT)
(m4_symbol_value_groks_macro): Likewise...

are stringized without preprocessor expansion.
* doc/m4.texinfo (Defn): Update comments to match reality.
(Debuglen): Update test now that user macros pass builtin tokens.
Stage 19a: sort and cache builtins loaded by a module.
Rather than repeatedly using dlsym to browse the builtin table,
copy off the table at module load time. Then, the input engine
merely refers to the copy instead of duplicating information.
Memory impact: slight penalty, due to more memory per module, but
offset by less memory in input engine.
Speed impact: slight improvement, due to faster builtin lookups.
* m4/m4module.h (m4_set_symbol_value_builtin): Delete. Use
m4_builtin_find_by_* instead.

(m4_builtin_find_by_name): Rewrite to use sorted table.
(m4_builtin_find_by_func): Change return type.

fields can be determined from builtin.
(builtin_peek, builtin_read, builtin_unget, init_builtin_token)
(m4__next_token): Alter parsing so that only init_builtin_token
consumes a builtin.

Fix nested builtin(`shift',$@) regression from 2008-02-23.
* m4/macro.c (make_argv_ref): Don't output expansion text when
making wrapper for builtin or indir.
* tests/builtins.at (builtin): New test.
* NEWS: Document the fix.
Reported by Andreas Schwab.
2008-03-04 Eric Blake <ebb9@byu.net>
The gnulib module free was deprecated.
* ltdl/m4/gnulib-cache.m4: Remove free module.
2008-02-29 Eric Blake <ebb9@byu.net>
Import news from 1.4.10b.
* NEWS: Update from branch.
2008-02-23 Eric Blake <ebb9@byu.net>
Stage 18: try harder to reuse argv in recursion.
When pushing arguments that contain an existing $@ ref, reuse the
ref rather than creating another layer of wrappers.
Memory impact: noticeable improvement, due to better $@ reuse.
Speed impact: noticeable improvement, due to O(n^2) to O(n)
reduction in unboxed recursion.
* m4/macro.c (make_argv_ref): Avoid wrapping $@ when possible.
(m4_push_args): Let make_argv_ref take care of pending data.
* doc/m4.texinfo (Improved foreach): Tweak wording to match new
performance capability.
* tests/others.at (recursion): Add tests to avoid performance
regression.
2008-02-22 Eric Blake <ebb9@byu.net>
Update NEWS.
* NEWS: Document change to __gnu__ on 2008-02-11.
Stage 17: pass argv through quoted strings.
Allow the concatenation of $@ references with other text input
inside quoted contexts, which requires distinguishing between a
wrapper around many arguments vs. a reference serving as part of a
single argument. Also optimize based on whether argv contains
builtin tokens that might need flattening to the empty string.
Memory impact: noticeable improvement, due to O(n^2) to O(n)
reduction from total reuse of $@ references.
Speed impact: noticeable improvement, due to O(n^2) to O(n)
reduction in boxed recursion.
* m4/m4module.h (m4_arg_equal, m4_arg_len): Add parameter.

Fix regression in argument collection, from 2008-01-21.
* m4/input.c (m4__next_token): When DEBUG_INPUT is defined,
undo argument collection optimisation for strings, so that
m4_print_token doesn't abort when it otherwise receives an
unprintable M4_SYMBOL_VOID type token.
2008-02-20 Eric Blake <ebb9@byu.net>
Stage 16: cache quotes and improve m4_arg_print.
Cache rather than always copying quotes when pushing $@ refs; in
particular, reconstruct single-byte quotes on the fly. Allow NUL
through m4wrap. Improve sharing of code that prints arguments.
Memory impact: slight improvement, due to cached quotes.

implementation, and allow embedded NUL.
(m4_print_token, pop_input, composite_print, composite_peek):

Avoid some magic numbers.
* m4/m4private.h (CHAR_EOF, CHAR_BUILTIN, CHAR_QUOTE, CHAR_ARGV)

Reported by Ralf Wildenhues.
2008-02-16 Eric Blake <ebb9@byu.net>
Add regression test for multi-character quote recursion.

(Improved foreach): Adjust dump from file.
Stage 15: return argv refs back to collect_arguments.
Collect an entire $@ reference at once rather than one argument at
a time, outside of quotes (but inside quotes, $@ is still
flattened for now). The skip_last field allows concatenation of
$@ with other text when collecting arguments.
Memory impact: noticeable improvement, due to better reuse of $@.
Speed impact: noticeable improvement, due to less parsing.

* modules/perl.c (perleval): Likewise.
Stage 14b: allow pushing argv references.
Push a $@ reference to the input engine in one go, rather than
pushing each element. For now, argument collection still gets one
argument of a $@ at a time; but the penalties of this patch make
it easier to manage $@ efficiently in future patches.
Memory impact: noticeable penalty, due to larger struct and O(n)
to O(n^2) on unboxed recursion.
Speed impact: noticeable penalty, due to more bookkeeping.
* m4/m4private.h (struct m4__symbol_chain): Add comma and quotes
fields.
(struct m4_macro_args): Add level field.

(expand_macro): Move argv cleanup...
(m4__arg_adjust_refcount): ...to this new function.
(m4_arg_symbol, m4_make_argv_ref, m4_push_arg): Factor...
(arg_symbol, make_argv_ref, m4__push_arg_quote): ...to these new
helper functions, to add parameters.
(m4_push_args): Adjust caller.
* m4/symtab.c (m4_symbol_value_print): Likewise.
Stage 14a: allow printing argv references.
Refactor symbol-value printing code for better sharing, and to
allow printing a contiguous text representation of a $@ ref.
Memory impact: none.
Speed impact: none.
* m4/m4module.h (m4_arg_print): New prototype.

2008-01-27 Eric Blake <ebb9@byu.net>
Stage 13: push composite text tokens.
Support pushing composite tokens, allowing back-references to be
reused through multiple macro expansions. Add hueristic that
avoids creating new reference when pushing existing references.
Memory impact: noticeable improvement due to better reference
reuse, except for O(n) to O(n^2) copying in boxed recursion.
Speed impact: slight penalty, due to more bookkeeping.

example.
2008-01-21 Eric Blake <ebb9@byu.net>
Stage 11: full circle for single argument references.
Pass quoted strings through to argument collection in a single
action, so that an argument can be reused throughout macro
recursion if it remains unchanged.
Memory impact: noticeable improvement, due to more reuse in
argument collection stacks; O(n^2) to O(n) on boxed recursion.
Speed impact: noticeable improvement, due to less copying.
* m4/m4module.h (m4_arg_text): Add parameter.
(M4ARG): Adjust.

Stage 10: avoid extra copying of strings and comments.
When collecting tokens that are immune to further expansion, avoid
copying data from one obstack to another by outputting it into the
destination obstack to begin with. Also reduce copying done in
format builtin.
Memory impact: slight improvement, due to better obstack usage.
Speed impact: noticeable improvement, due less data copying.
* ltdl/m4/gnulib-cache.m4: Import intprops and vasnprintf-posix
modules.
* m4/m4private.h (m4__token_type): Adjust prototype.

(translit): Make test take longer, to make quadratic algorithms
more apparent.
2007-12-20 Eric Blake <ebb9@byu.net>
Stage 9: share rather than copy single-arg refs.
Use hooks of previous patch to create back-references to arguments
in the input engine, and inline short text rather than always
creating a FIFO link. Also start testing embedded NUL behavior.
Until the argument collection engine also shares references, the
memory usage increases.
Memory impact: noticeable penalty, due to longer life of argv
changing O(n) to O(n^2) on boxed recursion.
Speed impact: slight improvement, due less data copying.
* ltdl/m4/gnulib-cache.m4: Import memmem and quote modules.
* m4/m4module.h (m4_arg_scratch): New prototype.

(m4_arg_scratch): New function.
(m4_make_argv_ref): Call new function.
(m4_push_arg): Push reference to $0.

references through rescanning.
* m4/symtab.c (m4_set_symbol_value_text): Weaken assertion.
* modules/m4.c (errprint, index): Handle NUL transparently.
(dumpdef, translit): Use scratch space, rather than expansion
stack.

2007-12-17 Eric Blake <ebb9@byu.net>
Stage 8: extend life of references into argv.
Add hooks to lengthen the lifetime of arguments reused in a macro
expansion, rather than always discarding arguments at the end of
expand_macro. Rework the expand_macro obstacks to handle longer
lifetimes. For now, the hooks remain unused.
Memory impact: slight penalty, due to larger structs.
Speed impact: slight penalty, due to more bookkeeping.
* m4/system_.h (obstack_regrow): Delete.

(process_macro): One less cast.
* m4/m4.c (m4_delete): Clean up arg_stacks.
* m4/input.c (make_text_link): Use new field.

Stage 7: use chained input support in input parser.
Allow the LIFO input engine to rescan a macro expansion composed
of smaller chunks of FIFO data, rather than the old approach of a
monolithic string. For now, all chunks are still copied.
Memory impact: slight penalty, due to FIFO chain overhead.
Speed impact: slight penalty, due to extra bookkeeping.

2007-12-08 Eric Blake <ebb9@byu.net>
Stage 6: convert builtins to push arg at a time.
Add new methods to factor all builtins whose expansion includes an
argument, making back-reference creation easier in future patches.
Factor out length-limited printing to obstacks, and use -1 rather
than 0 for unlimited length.
Memory impact: none.
Speed impact: slight improvement, due to better code sharing.
* m4/m4module.h (m4_shipout_text): Rename...
(m4_divert_text): ...to this, to avoid confusion with m4_shipout_*
that does not worry about sync lines.
(m4_shipout_string_trunc): New prototype.
* m4/output.c (m4_shipout_text): Rename...
(m4_divert_text): ...to this.

zero.
2007-12-07 Eric Blake <ebb9@byu.net>
Minor security fix: Quote output of mkstemp.
* modules/m4.c (m4_make_temp): Produce quoted output.
* doc/m4.texinfo (Mkstemp, Mkdtemp): Update the documentation and
tests.
Stage 5: add notion of quote age.
Cache the quoting rules that were in effect when a string was
parsed, to avoid reparsing that string if no changequote or other
quote age change took place in the meantime. A quote_age of 0 is
always safe, but does not benefit from caching.
Memory impact: slight improvement, due to smaller struct in input
engine.
Speed impact: slight penalty, due to more bookkeeping.
* m4/m4module.h (m4_get_symbol_value_quote_age): New prototype.
(m4_set_symbol_value_text): Adjust prototype.

Finish making struct opaque to all but the input engine, by
reworking obstack usage in expand_macro to better support creation
of a $@ reference. Canonicalize the empty argument, to allow
pointer comparison optimizations.
Memory impact: slight penalty, due to larger struct.
Speed impact: slight improvement, due to fewer function calls.
* m4/system_.h (obstack_regrow): Fix precedence.
* m4/m4module.h (m4_arg_equal, m4_arg_empty, m4_make_argv_ref):

length-based handling allows NUL through part but not all of M4.
2007-11-28 Eric Blake <ebb9@byu.net>
Stage 3a: cache length, rather than computing it, in libm4.
Cache the length of a token in the input engine and symbol table,
to avoid repeating lots of strlen calls. Additionally, by using
obstack length rather than strlen, the input engine can now
support embedded NUL.
Memory impact: slight penalty, due to larger struct.

usage.
2007-11-24 Eric Blake <ebb9@byu.net>
Stage 1: convert m4_symbol_value** into new object.

performs cleanups, such as handling of embedded NUL, made easier
by the code refactoring.
Stage 0: Fix memory leak in tail recursion.
Free expansion text in the input engine as soon as it is parsed,
rather than when the recursive expansion completes.

`awk' so that the user can use an alternative implementation
if the first awk in PATH doesn't behave as expected.

with Darwin 8.10.1. Capture $3 into a variable too to work-
around that problem.

M4 was designed to have a small number of header files defining
the interfaces to several source files each. Keeping this in
mind allows us to tidy things up considerably. Having done this,

here...

The regs_allocated field in a struct re_pattern_buffer refers
to the state of a particular re_registers struct when used in
successive matches using the same compiled pattern. Avoid a

* modules/gnu.c (m4_pattern_buffer): Wrapper struct for associated
pattern buffer and registers.
(m4_regexp_search): New function to call re_regexp_search with

* Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit.
(clean-local): Split into and depend upon...
(clean-local-tests, clean-local-src): ...these two. The latter
removes the libtool object directory below `src', to work around
a buglet in Automake, failing to list it.
(EXTRA_DIST): Distribute modules/perl.c.
2006-06-19 Eric Blake <ebb9@byu.net>
* Makefile.am ($(srcdir)/doc/m4.1): No need to list $(srcdir) in

(stamp-vcl): Update to use libtool's algorithm.
(EXTRA_DIST): Distribute stamp-vcl.
Reported by Ralf Wildenhues.
(TESTSUITE): Revert earlier change that used absolute path, as
that broke 'make dist' in VPATH. Stick with $(srcdir) instead.
(EXTRA_DIST): Revert earlier change of $(TESTSUITE).
(TESTS_ENVIRONMENT) [USE_GMP]: Revert earlier addition, since
atlocal takes care of it instead.
(check-local, installcheck-local, clean-local): Inline absolute
path to testsuite here, rather than relative path to testsuite
elsewhere.
2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* m4/m4private.h (DELETE): Cast away const here...
* src/stackovf.c (stackovf_exit): ...to avoid cast-as-lvalue here.

variable warning.
2006-06-19 Eric Blake <ebb9@byu.net>
* Makefile.am (doc/m4.1): Build in $(srcdir), to match where
.info pages are built.
Reported by Ralf Wildenhues.
(EXTRA_DIST): Inline definition of testsuite, so that make dist
works again.
2006-06-16 Eric Blake <ebb9@byu.net>
Follow recommendations from autoconf manual for autotest.
* Makefile.am (TESTSUITE): Factor the $(srcdir) out of uses, and

Reduce compiler warnings. Inside GMP, mpq_t is an array type, so
const mpq_t is not assignable from plain mpq_t. Avoid
type-punning warnings caused trying to mix these types.
* modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
(numb_rshift, numb_divide, numb_modulo): Remove const qualifier.

* NEWS: Match current version number.
2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* Makefile.am (AM_CPPFLAGS): Add $(LTDLINCL), so the right
ltdl.h is used.
* bootstrap: Do not run libtoolize manually, this is done
correctly by autoreconf. Invoke autoreconf with --no-recursive
to avoid unnecessary rerunning of autotools for libltdl.
2006-06-13 Eric Blake <ebb9@byu.net>
* THANKS: Update.
2006-06-12 Eric Blake <ebb9@byu.net>

done by gnulib or automake, or which autoconf has declared
obsolete.

worthwhile.
* ChangeLog: Change encoding to UTF-8.
Avoid compiler warnings.
* m4/macro.c (trace_format): Don't mark this as a printf format,
since we don't accept the same set of modifiers as printf. It
would be nice if gcc let us specify a custom format archetype.

* po/POTFILES.in (src/getopt.c, src/version-etc.c): These files live
in src, not gnu.
2006-05-06 Eric Blake <ebb9@byu.net>
* configure.ac (LT_CONFIG_LTDL_DIR): Inform libtool which
subdirectory to use.
(support for -pipe): Move after LT_INIT, since it relies on
libtool internals.
2006-05-05 Eric Blake <ebb9@byu.net>
* Makefile.am (doc/m4.1): Use $@, not $(srcdir)/doc/$@.
* THANKS: Update.

Reported by Eric Blake <ebb9@byu.net>
2005-12-04 Gary V. Vaughan <gary@gnu.org>
* bootstrap (func_update_po): Test and set $WGETFLAGS to disable
http caching as -C is no longer supported by wget 1.10.x.
Reported by Eric Blake <ebb9@byu.net>
2005-10-20 Gary V. Vaughan <gary@gnu.org>
* m4/module.c (caller_id): To match libtool-2.0 interface, changed
to ...
(iface_id): ...an lt_dlinterface_id type.
(m4__module_find): New abstraction for lt_dlhandle_fetch. Use
throughout, instead of calling obsolete lt_dlhandle_find directly.

throughout, instead of calling obsolete lt_dlhandle_next.
* m4/m4private.h (m4__module_find): Declare it.

correctly determine module source directories whether gnulib-tool
is given as a relative or absolute path, or is found by searching
PATH.
Reported by Eric Blake <ebb9@byu.net>
2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2005-05-07 Gary V. Vaughan <gary@gnu.org>
Since most of the build is handled from a single Makefile.am now,
we can teach make about the dependencies between the m4 binary and
the preopened modules it is built against:
* configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
preopened modules.
* Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
of the preopened modules have changed.
2005-05-07 Gary V. Vaughan <gary@gnu.org>
* configure.ac (gl_MODULES): Add mkstemp for machines that don't
have a native implementation.
2005-05-06 Gary V. Vaughan <gary@gnu.org>
* src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
handled already by gnu/exit.h.
* configure.ac (gl_MODULES): Add assert to support a
--disable-assert configure time option for NDEBUG setting.
* Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
* bootstrap (src_modules): Add version-etc-fsf.

recognition macros.
* src/freeze.c (produce_frozen_state): Use \n line-endings even
on Windows, so that the frozen file reader will work.
Reported by Josef T. Burger <bolo@bolo.com>
2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
Forward port of a patch that allowed m4-1.4.2 to compile on
QNX 6.3:
* configure.ac (AC_CHECK_HEADERS): Add signal.h,
sys/signal.h.
* src/m4.h: And include them as appropriate.
* src/main.c, src/stackovf.h: Don't include signal.h literally;
m4.h will include the correct file.
2005-05-04 Gary V. Vaughan <gary@gnu.org>
* m4/m4private.h: Make errno visible for the sources patched
below.
2005-05-04 Paul Eggert <eggert@twinsun.com>

M4ERROR relies on this.
* modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
* modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
* m4/path.c (m4_path_search): Don't let "free" trash errno when
returning NULL.
* m4/output.c (m4_insert_file): Don't assume errno has a valid
value simply because fread returns zero. This fixes a
portability bug reported by Marion Hakanson in
<http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
2005-05-04 Santiago Vila <sanvila@debian.org>

unbuffered I/O, as this breaks on the Hurd.
2005-05-04 Gary V. Vaughan <gary@gnu.org>
Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
and libtoolize does a better job of ltdl importing now too, so
take advantage of that while updating the tree:
* acm4, config: Moved from here...
* ltdl/m4, ltdl/config: ...to here.
* doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
src/Makefile.am, tests/Makefile.am: Removed...
* Makefile.am: ...and migrated to here, with adjustments to
compensate for relative path differences.
* commit: Adjust relative paths.
* configure.ac: Adjust relative paths.
(AC_PREREQ): 2.59 isn't strictly new enough, we also need a
patch.
(LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
the meanwhile, CVS HEAD libtool is needed.
(AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
stricly new enough, we also need a patch.
(AM_PROG_CC_C_O): Required for subdir-objects in Automake.
(AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
(gl_MODULES): Don't list getopt and version-etc, as they don't
belong in libm4.
* bootstrap: After running gnulib-tool to import the listed
modules, fetch getopt and version-etc into src manually.
(ltdldir): Change to ltdl.
* src/main.c: Adjust for changes in version-etc API.
* ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
but works when the getopt module isn't to be included in the lib.
* README: Add note about patching autoconf and automake to
bootstrap CVS m4.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
* doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
empty file rather than to a nonexistent file. This closes a
common security hole.
* modules/m4.c (m4_maketemp): Implement the above, by using
mkstemp rather than mktemp.

Protect definitions from macro expansion under -DNDEBUG by
parenthesising the expanded function names.
* m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
(m4_get_syntax_bcomm, m4_get_syntax_ecomm)
(m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
(m4_is_syntax_macro_escaped): Similarly protect function
definitions from macro expansion under -DNDEBUG by #undefing the
matching macro names before each definition. Also, move all the
function definitions to the end of the file so that any
invocations in the rest of the file pick up the fast macro
versions.

2004-09-23 Gary V. Vaughan <gary@gnu.org>
* po/POTFILES.in: Reflect move of gnulib files from gnulib/m4
to gnu.
2004-09-23 Gary V. Vaughan <gary@gnu.org>
* src/main.c: Include gnulib files from the correct directory.
* gnulib/*: Don't store any of the gnulib files in arch, as they
generate spurious changes.
* Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
gnulib macros now share our macro directory.
(SUBDIRS): Descend into `gnu' rather than `gnulib'.
* bootstrap: Call gnulib-tool to import from the gnulib tree.
(gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
the gettext macros from autopoint that overwrite the gnulib-tool
imported versions. Import sources and Makefile.am into the `gnu'
directory. Changed all callers.
* configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
gl_INIT): Call these gnulib-tool macros instead of the hardcoded
for imported modules.
* acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
hardcoding the gnulib macros they wrap.
2004-07-15 Gary V. Vaughan <gary@gnu.org>
Latest CVS libtool can preload modules in libraries, including
its own module loaders! Tweak m4 so that it doesn't try to treat
libltdl's module loaders as m4 modules when freezing and on exit:
* gnulib/acm4/*.m4: Don't store these files in arch since they
generate spurious changes.
* bootstrap: Simplify initial libtoolize call, since CVS
libtoolize is smarter these days.
* doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
build.
* m4/module.h (m4__module_exit): Missing declaration.
* m4/m4private.h (m4__module_next): New function declaration.
* m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
encapsulation. Changed all callers.
(m4__module_interface): New function to verify m4 loadable module
interfaces.
(m4__module_init): Register the interface validator.
(m4__module_exit): Only close my own modules.
* modules/m4.c (unistd.h): Provide missing declaration.
(m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
(m4_expand_ranges): More missing declarations.
* modules/modtest.c (export_test): Ditto.
* src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
* src/main.c (main): Bump copyright year.
* tests/modules.at: Fix sed syntax error.
2004-06-17 Gary V. Vaughan <gary@gnu.org>
Tweaking to enable compilation with latest CVS libtool and
libltdl. We can't just dump the library files directly into the
m4 directory anymore now that libltdl is built from pieces itself:
* bootstrap: Rewritten to use latest libtoolize sanely, and to
set up libltdl subdirectory.
* configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
gnulib subdirectory's config.
(TIMESTAMP): Use $ac_aux_dir for VPATH builds.
(m4_pattern_forbid): Remove the cruft to deal with renamed jm_
macros from gnulib.
(AC_LIB_LTDL): Latest libltdl is a sub-project with its own
configure.ac, so use AC_WITH_LTDL instead.
* Makefile.am (SUBDIRS): Add libltdl.
* acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
gl_INCLUDED_REGEX.
* m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
(libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
(libm4_la_LIBADD): Add LIBLTDL.
* m4/ltdl.c, m4/ltdl.h: Removed.
* m4/m4module.h: Include canonical ltdl.h.
* po/*.po: Updated.
2004-06-14 Gary V. Vaughan <gary@gnu.org>
* gnulib/import: Now updates makefile fragments, and configure.ac.
* gnulib/m4/gnulib.am: New file. Generated makefile fragments.
* gnulib/m4/Makefile.am: include it.
* gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
gnulib/acm4/xsize.m4: New macro files from latest gnulib import.

gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
Updated source files from latest gnulib.
2004-02-29 Gary V. Vaughan <gary@gnu.org>
* config/mailnotify: New file for mailing commit notifications,
imported from cvs-utils.
* commit: Updated from cvs-utils and tweaked for m4.
2003-12-01 Gary V. Vaughan <gary@gnu.org>
* config/mkstamp: Updated from CVS libtool.
* configure.ac: Generate a gnu coding standards compliant version
number, and use it for the banner.
* Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
mhen the TIMESTAMP changes in ChangeLog, but the file modification
time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
contain the previous version number.
* src/main.c: Make --version output conform to the GNU standard.
* configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
* modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
time_la_SOURCES): ...so that these are defaulted correctly, and
can be removed from this file.
(AM_LDFLAGS): Add -module...
(gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
the individual settings can be removed.
* m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
* module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
time_la_LIBADD): ...so that these are picked up as a deplib of
libm4 and don't need to be set explicitly.
2003-11-18 Gary V. Vaughan <gary@gnu.org>
* modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
from the standard build. It is too fragile.
* gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
CVS libtool after merging m4 changes across to libtool.
* m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
* m4/path.c (search_path_add): Ditto.
2003-11-13 Gary V. Vaughan <gary@gnu.org>
* configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
libtool tags we don't use in configure. This reduces the size
of the script from over 1Mb to under 700Kb.
2003-11-13 Gary V. Vaughan <gary@gnu.org>
The import script was not written properly, and the last gnulib
import was incomplete. Fixed that problem, and reimport our
gnulib dependencies, which picks up the address calculation
overflow checks described by Paul below. Also tweak the clients
of the gnulib xalloc module not to use deprecated macros:
* gnulib/import: Recurse through module dependencies rather than
naively descending only one level.
* configure.ac: Add calls to gnulib's strnlen and extension module
macros.
* gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
extension modules.
* gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
gnulib.
* gnulib/acm4/libtool.m4: Updated from CVS libtool.
* m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
place of `xcalloc (1, S)'.
* m4/m4.c (m4_create): Likewise.
* m4/m4private.h (m4_symbol_value_create): Likewise.
* m4/symtab.c (symtab_fetch): Likewise.
* m4/syntax.c (m4_syntax_create): Likewise.
* src/freeze.c (reload_frozen_state): Likewise.
* m4/path.c (search_path_add): Eliminate use of deprecated NEW
macro.
* m4/symtab.c (m4_symtab_create): Likewise.
2003-11-13 Gary V. Vaughan <gary@gnu.org>
* tests/module.at: Comment typo.
2003-10-10 Gary V. Vaughan <gary@gnu.org>
* tests/modules.at (modules: importing): Apply some lateral
thinking, and use AT_CHECK to compare the output of a sed pass
over stderr against the canonical strerror string.
* tests/modules.at (modules: importing): Edit the generated stderr
output to canonicalize strerror output, before a comparison.
2003-10-10 Gary V. Vaughan <gary@gnu.org>
Tru64UNIX perl is sloppy with namespace pollution. This patch is
careful not to trip over the mess:
* modules/perl.c: Some builds of perl install headers that contain
`#define try __builtin_try'. Be sure to undefine that macro
before `m4/hash.h' gets included, which uses the `try' symbol.
* m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
`false' before including `stdbool.h'.
(DELETE): This symbol is not in m4's namespace, and is in any
case only used internally...
* m4/m4private.h (DELETE): ...so move it to here.

2003-10-08 Paul Eggert <eggert@twinsun.com>
Don't use XMALLOC and XCALLOC. Once we install the
corresponding patch into gnulib, this will fix some
address-calculation overflow bugs on hosts where calloc (A, B)
returns garbage when A*B overflows.
* m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
xmalloc, XCALLOC with xcalloc.
* m4/m4.c (m4_create): Likewise.
* m4/m4private.h (m4_symbol_value_create): Likewise.
* m4/output.c (m4_output_init): Likewise.

Gary V. Vaughan <gary@gnu.org>
* bootstrap: Separate options.
* configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
* gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
not set.

(modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
(shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
$(LTLIBINTL) for gettext support on cygwin.
* src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
have $(LTLIBINTL) from the preloaded module la files.
* README: Remove the warning about using --disable-nls on Windows
machines.
2003-09-15 Gary V. Vaughan <gary@gnu.org>
* gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
is required.
2003-09-12 Gary V. Vaughan <gary@gnu.org>
* doc/STYLE: Document the gnulib header naming conventions, and
#include policy.

2003-09-12 Gary V. Vaughan <gary@gnu.org>
Replace the getopt code with CVS gnulib getopt. The source files
detect whether they are in a glibc environment and preprocess away
all of the code if there is a system getopt, so we can compile
them into the m4 executable unconditionally:
* gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
gnulib/config/getopt.m4: Import getopt module from CVS gnulib.

2003-09-12 Gary V. Vaughan <gary@gnu.org>
* configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
* config/Makefile.am: Removed. Automake 1.8 distributes the files
in this directory automatically.
* Makefile.am (EXTRA_DIST): Except config/mkstamp.
* configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
isn't set yet.
* m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
inline.
* modules/Makefile.am (pkglibexecdir): Set it here.
(pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
* gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
Import regex module from CVS gnulib.
* gnulib/config/restrict.m4: Ditto for dependee module restrict.
* config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
do extra substitutions for Makefile.
* configure.ac: Use it.
* gnulib/m4/Makefile.am: Maybe install regex.h after linking it
from regex_.h if necessary.
* m4/system_.h: Include the correct version of regex.h.
* m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
version.
* po/POTFILES.in: Use new location of regex.c.
* gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
realloc.c: automake distributes these files already.
2003-09-12 Gary V. Vaughan <gary@gnu.org>
Replace the xstrzdup code by importing the xstrndup module from
CVS gnulib, along with its dependencies: strndup and strnlen:
* gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
gnulib/config/xstrndup.m4: Import xstrndup module from CVS
gnulib.
* gnulib/m4/strndup.c, gnulib/m4/strndup.h,
gnulib/config/strndup.m4: Ditto wrt strndup.
* gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
strnlen.
* gnulib/m4/Makefile.am: Add rules from newly imported modules.
However, contrary to gnulib, we install xstrndup.h.
* configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
* gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
is an artifact of the old m4 portability layer.
* configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
* m4/system_.h: Include xstrndup.h.
* m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
2003-09-11 Gary V. Vaughan <gary@gnu.org>
Reimport the latest xalloc module from CVS gnulib, and adjust the
m4 sources to take advantage of xalloc xfree. Also create a new
macro DELETE with the same semantics as the old m4 XFREE macro,
and carefully tweak callers:
* gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
gnulib.
* m4/utility.c (xfree): Removed. This function is now supplied by
gnulib xalloc.
* m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
* m4/path.c (search_path_add): Use NEW macro from xalloc.h.
* m4/symtab.c (m4_symtab_create): Ditto.
* m4/system_.h: Removed XFREE redefine.
(DELETE): New macro with same functionality as the original m4
XFREE macro, but based on xalloc.h now. Changed all callers.
* src/main.c (main): Use XMALLOC macro.
* m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
instead of XFREE.
* m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
2003-09-10 Gary V. Vaughan <gary@gnu.org>
Import the xalloc module from CVS gnulib, along with its
dependencies: exitfail, malloc and realloc. We had different
semantics for our XFREE and a function xfree() not supplied by
gnulib, so also a bit of work to keep everything running
smoothly:
* configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
(gl_XALLOC): Use gnulib equivalents.
* gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
* gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
* gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
realloc.
* gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
* gnulib/m4/Makefile.am: Add fragment from gnulib for newly
imported modules.
(pkgincdir): Removed. Use pkgincludedir instead.
* m4/m4private.h (XFREE): xfree already checks for NULL.
* m4/system_.h: Use xalloc module, and remove macros already
supplied by xalloc.h.
* m4/utility.c (xfree): xalloc does not yet implement xfree, so
moved the old definition from m4/xmalloc.c to here for now.
2003-09-09 Gary V. Vaughan <gary@gnu.org>
Import the error and progname modules from CVS gnulib. Our old
error.c subsumed the functionality of both, so a little adjustment
was required to accomodate the split in sources. Also added more
wrapper macros to choose between a system installed error.h or our
shipped gnulib error module:
* m4/error.c, m4/error.h: Removed.
* m4/Makefile.am: Adjust.
(pkgincdir): Removed. Use pkgincludedir instead.
* m4/module.h, src/main.c: Don't include `m4/error.h'.
* m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
error.h.
* gnulib/m4/progname.c: Imported from CVS gnulib.
* gnulib/m4/progname.h: Ditto.
* src/main.c: Adjust to use progname module.
* gnulib/m4/error.c: Imported from CVS gnulib.
* gnulib/m4/error_.h: Ditto.
* gnulib/m4/Makefile.am: Build the error module into our libgnu.la
if appropriate, and link a local error.h if the system version is
missing.
(libgnu_la_SOURCES) Add progname module sources.
* gnulib/config/error.m4: Imported from CVS gnulib.
* gnulib/config/strerror_r.m4: Ditto.
* config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
to have ERROR_H for Makefile substitutions and tell system.h
whether the system error.h should be used, or a locally installed
version.
* configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
2003-09-09 Gary V. Vaughan <gary@gnu.org>
* gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
s/gettext_.h/gettext.h/.
* bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
automake have been fixed.
* config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
2003-09-09 Gary V. Vaughan <gary@gnu.org>
The gnulib obstack module requires the gnulib gettext module for
systems that do not have GNU gettext installed. Because we use
-Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
that directory incase it clashes with the system gettext.h. This
delta uses gettext_.h and extra rules in the Makefile to make a
link to gettext.h when needed:
* Makefile.am (auxdir): Removed. No longer used.
* configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
(TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
moved.
(AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
Makefile based build.
(AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
of the macros are kept.
* Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
* configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
* config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
distributes these automatically.
* config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
warning from automake-1.7a.
* config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
all callers.
* config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
wrt. m4_FUNC_OBSTACK.
* config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
wrt. m4_sys_STACKOVF.
* config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
wrt. _m4_LIB_GMP, m4_LIB_GMP.
(ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
respectively.
* config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
* gnulib/m4/Makefile.am: Added a new block to make an appropriate
gettext.h link on deficient systems.
(pkginc_HEADERS): Mention $(GETTEXT_H).
(EXTRA_HEADERS): Mention gettext.h.
* gnulib/config/gettext_.h: New file from gnulib's gettext.h.
* gnulib/config/codeset.m4, gnulib/config/gettext.m4,
gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
gnulib/config/po.m4, gnulib/config/progtest.m4,
gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
gnulib/config/ulonglong.m4: Imported from CVS gnulib.
2003-09-05 Gary V. Vaughan <gary@gnu.org>
We can't mirror the gnulib directory structure here, since we need
to be able to eg. `#include <m4/obstack.h>' from our source files,
which is much easier if the local obstack.h is created in a
directory named m4. Rather than trying to symlink everything into
the m4 directory, now we build a libtool convenience library from
the sources we get from gnulib and link that with libm4.la:
* gnulib/config/extensions.m4: Imported from CVS gnulib.
* gnulib/config/unlocked-io.m4: Ditto.
* gnulib/m4/unlocked-io.h: Ditto.
* gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
* gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
* m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
* m4/Makefile.am: Adjust.
* gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
macros we redistribute.
* gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
library among others.
(GNULIB_SRCS, GNULIB_MACROS): Removed.
* Makefile.am (ACLOCAL_AMFLAGS): Adjust.
* config/m4-obstack.m4: Adjust.
* po/POTFILES.in: Adjust.
* configure.ac: Reformatting. Call newly imported gnulib macros.
* m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
bogus calls of `#include "m4.h"'.
* Makefile.am: INCLUDES has been deprecated in favour of
AM_CPPFLAGS.
* m4/Makefile.am: Ditto.
* modules/Makefile.am: Ditto.
* src/Makefile.am: Ditto.
2003-09-05 Gary V. Vaughan <gary@gnu.org>
* config/Makefile.am: Reverting yesterdays patch for VPATH builds.
2003-09-04 Gary V. Vaughan <gary@gnu.org>
Migrate the obstack support into the gnulib directories for easy
synchronisation with upstream files in gnulib:
* config/gnu-obstack.m4: Moved from here...
* config/m4-obstack.m4: ...to here.
* config/Makefile.am (SPECIFIC_MACROS): Adjust.
* m4/obstack.c, m4/obstack_.h: Moved from here...
* gnulib/obstack.c, gnulib/obstack.h: ...to here.
* po/POTFILES.in: Adjust.
* gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
* m4/Makefile.am: Add a whole new section to link the obstack
sources from the gnulib tree if necessary.
* gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
from gnulib.
* config/m4-obstack.m4: Rewrite as a wrapper for
gnulib/m4/obstack.m4.
2003-09-04 Gary V. Vaughan <gary@gnu.org>
GNU M4 currently builds with a number of files adapted from
upstream sources. Recently the gnulib project on savannah.gnu.org
has pulled together a great many of these externally maintained
files. This delta is the beginnings of isolating those files
maintained in gnulib to make it easy to synchronise M4 with the
upstream files prior to releases.
* Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
directory.
(SUBDIRS): Added new gnulib subdirectory.
* configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
* config/stdbool.m4: Moved from here...
* gnulib/m4/stdbool.m4: ...to here.
* m4/stdbool_.h: Moved from here...
* gnulib/lib/stdbool_.h: ...to here.
* gnulib/Makefile.am: New file. Make sure the gnulib tree is
distributed.
* m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
code to work with new stdbool_.h location.
(gnulib_srcdir): New.
2003-09-04 Gary V. Vaughan <gary@gnu.org>
* config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
(STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
builds to work.
(SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
(EXTRA_DIST): Use it.
* bootstrap: CVS autoreconf leaves file droppings. Remove
aclocal.m4t incase autoreconf doesn't.
2003-08-29 Gary V. Vaughan <gary@gnu.org>
* m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
the other gnulib imports, renamed to m4/obstack_.h.
* m4/obstack.c: Updated from CVS gnulib.
* m4/Makefile.am (EXTRA_HEADERS): Adjust.
* config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
header tests from gnulib obstack module. AC_CONFIG_LINKS knows
about vpath already, and $top_srcdir upsets CVS Automake, so the
$top_srcdir reference was removed.
* m4/system-h.in: For consistency with the gnulib imports, renamed
to m4/system_.h.
* m4/Makefile (EXTRA_HEADERS): Adjust.
* configure.ac (AC_CONFIG_FILES): Adjust.
* m4/stdbool_.h: New file from gnulib for systems without their
own.
* m4/Makefile.am: Add snippets from gnulib for C99 bool support.
* config/stdbool.m4: New file. Macros from gnulib for same.
* configure.ac: Use it.
2003-08-27 Gary V. Vaughan <gary@gnu.org>

ac_default_headers is an autoconf internal variable.
* config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
* config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.

delta.
2003-08-15 Gary V. Vaughan <gary@gnu.org>
* configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
C99 bool.
* system-h.in (m4_boolean): Removed in favour of using C99 bool if
possible or faking one with a typedef. Changed all callers.
2003-08-15 Gary V. Vaughan <gary@gnu.org>
Still cleaning up the users' module API, by taking out the stuff
that isn't used by any existing modules, and moving specialised
functions out of libm4 and into the module they are used by.
* m4/m4module.h (m4_skip_space): No need to export this. Moved...
* m4/utility.c (m4_skip_space): ...to here the home of its only
use, made static and renamed to `skip_space'. Changed all
callers.
* m4/m4module.h (m4_expand_ranges): Removed prototype.
* m4/utility.c (m4_expand_ranges): Moved definition from here...
* modules/m4.c (m4_expand_ranges): ...to here, and exported using
ltdl.
* modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
casting .
* modules/gnu.c (builtin_syntax): Import and use in this
builtin implementation.
* m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
Not used. Deleted.
* m4/macro.c (trace_flush): Except here where the macro is now
manually inlined.
* m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
(M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
moved...
* m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
(M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
2003-08-14 Gary V. Vaughan <gary@gnu.org>
* config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
compiler based AC_CHECK_HEADER that was introduced in
autoconf-2.56.
* config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
* config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
* configure.ac: Use renamed M4_AC_LIB_GMP.
* config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
macro that requires arguments! This stops the shell's bad
substitution error at configure time.
* tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
variables to the testsuite shell. Set the value of USE_GMP so
that the gmp test will run!
(check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
2003-08-11 Gary V. Vaughan <gary@gnu.org>
Libltdl already has an excellent mechanism for accessing C symbols
in modules. Lets use that! Remove all the exporting cruft and
just use lt_dlsym in conjunction with a few conventions to
simplify module writers' jobs. Also removed the table address
caching code and otherwise simplified the module loader quite a
bit. To access exported symbols in other modules, first the
exporting module must name the symbols <modname>_LTX_<symname>,
and the importing module must define a function type called
<symname>_func. The importer then adds
M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
that wishes to call out to the exported functions. Care must be
taken that <symname> is non-NULL in the importing module incase
M4_MODULE_IMPORT fails, but otherwise it can be called as if the
definition was in the importers source. Study
`modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
m4_module_import will attempt to automatically load a module
required for symbol access if it is not loaded already.
* TODO: Removed the items fixed in this delta.
* m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
module name.
* m4/ltdl.h (lt_dlhandle_find): Declare it.
* m4/module.c (m4_module_unload): Use it.
* src/freeze.c (reload_frozen_state): Ditto.
* m4/m4module.h (m4_export): Deleted. Removed all references.
(M4_MODULE_IMPORT): New user convenience macro for importing
arbitrary symbols from other modules.
* m4/module.c (m4_module_import): New function to service
M4_MODULE_IMPORT macro.
(module_data): Removed. Looking up the tables on demand with
lt_dlsym, rather than caching their addresses here simplifies the
code substantially.
(m4_get_module_builtin_table, m4_get_module_macro_table):
Removed. Changed all callers.
(set_module_macro_table, set_module_builtin_table): Renamed to
install_macro_table and install_builtin_table respectively, and
simplified now that the cache is no more.
* modules/gnu.c (builtin_symbols): Use this new mechanism to
import m4_dump_symbols from the m4 module.
(builtin_esyscmd): Likewise for m4_set_sysval and
m4_sysval_flush.
* modules/m4.c (m4_export_table): Removed. Functions are
addressed with the new mechanism which doesn't need this.
(m4_set_sysval): New exported accessor function to prevent
problems with variable access on inferior architectures.
* modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
(m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
that we can have some type safety.
* modules/modtest.c (export_test): C level exported function for
testing the new import mechanism.
* modules/import.c: New file for the import end of the test.
* modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
* tests/modules.at: New test cases for intermodule symbol
importing.
2003-08-07 Gary V. Vaughan <gary@gnu.org>
* m4/m4module.c (m4_string): Moved from here...
* m4/m4private.c (m4_string): ...to here.
* m4/utility.c (dumpdef_cmp): Removed stale declaration.
2003-07-29 Gary V. Vaughan <gary@gnu.org>
* m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
already available to module writers through
m4_{get,set}_nesting_limit_opt(), so moved from here...
* m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
(m4_create): Use it.
2003-07-28 Gary V. Vaughan <gary@gnu.org>
Aside from auditing path.c for m4module.h api obfuscation, this
delta introduces the concept of private struct members in opaque
data types to GNU m4: See the STYLE file for details.
* TODO: Remind ourselves that a rewrite of path.c is needed.
* m4/m4module.h (m4_search_path, struct m4_search_path_info):
Moved from here...
* m4/m4private.h (m4__search_path, m4__search_path_info): ...to
here and renamed. These type definitions are for internal api use
only. Changed all callers.
* m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
Moved from here...
* m4/path.c (search_path_env_init, search_path_add): ...to here
and renamed. These calls were never used outside this file.
Changed all callers.
(dirpath): Moved functionality of this static declaration...
* m4/m4private.h (struct m4): ...to this new internal only
search_path field. Changed all callers.
(m4__get_search_path): Added new internal api accessor.
* m4/path.c (m4_search_path_info_new): Removed. Not used.
(m4_include_init): Removed...
* m4/m4.c (m4_create): ...because the new m4 field is now
initialised here.
(m4_delete): Recycle search_path memory.
* src/main.c (main): Don't call m4_include_init now that it's
gone!
* doc/STYLE: Document convention for private fields in opaque
ADTs.
2003-07-24 Gary V. Vaughan <gary@gnu.org>
Sometimes exporting the address of a symbol from a module isn't
enough for other modules to call that symbol correctly. If
custom data types are used for function parameters, they need to
be known to the caller. This change introduces the concept of
$(prefix)/include/modules/$(modulename).h to declare those
structures. Also we move m4_dump_symbols from libm4 to the m4
module to show this concept in action.
* m4/m4module.h (m4_dump_symbol_data): Moved from here...
* modules/m4.h (m4_dump_symbol_data): ...to this new file for
exporting data structures from modules/m4.c.
* modules/m4.c, modules/gnu.c: Include it.
* modules/Makefile.am (pkgmodinc_HEADERS): Install it.
* m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
prototypes.
* m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
Moved from here...
* modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
...to here, with slight renaming.
(m4_export_table): Prototype and add m4_dump_symbols.
* m4/symtab.c (m4_is_symbol_value_void): Needed for an external
definition of m4_dump_symbols.
* m4/m4module.h (m4_is_symbol_value_void): Prototype it.
* m4/m4private.h (m4_is_symbol_value_void): Fast macro version.

Create an export table in modules/m4.c in readiness for beefing up
the module loader to track module exports and imports.
* m4/m4module.h (m4_debug_flush_files): Removed prototype.
* m4/debug.c (m4_debug_flush_files): Moved...
* modules/m4.c (m4_sysval_flush): ...to here and renamed.
* modules/gnu.c (builtin_esysval): Use it.
* m4/m4module.h (m4_export): New type for declaring module symbols
for export.
* modules/m4.c (m4_export_table): List symbols exported from this
module for use by other modules.
2003-07-24 Gary V. Vaughan <gary@gnu.org>
An experiment: There is loads of code in libm4 which should be in
the m4 module, but is also used by another module. Just because
some linkers won't cope with calls across dynamic runtime loaded
objects I initially left the code in libm4. It will tidy the
module api immensely if this code moves to the right place, I just
need to remember to invent a suitable calling mechanism at some
point. For now, only modules that are statically linked and
preloaded will get this treatment, so the only platforms that will
break are those that require all symbols to be resolved at link
time.
* TODO: Reminder that what I am doing could reduce portability
unless I do something more robust later.
* m4/m4module.h (m4_sysval): No longer exported from libm4.
* m4/utility.c (m4_sysval): No longer declared in libm4.
* modules/Makefile.am: Reformatting.
* modules/m4.c (m4_sysval): Declare it at place of use.
* modules/gnu.c (m4_sysval): Import it for use in esyscmd.
2003-07-23 Gary V. Vaughan <gary@gnu.org>
* m4/m4module.h: Reformatting and rearranging lines a bit.
(m4_obstack): Save typing by typedefing `struct obstack'. Changed
all users.
(m4_call_macro, m4_expand_input): Renamed...
(m4_macro_call, m4_macro_expand_input): ...to these. Changed all
callers.
(m4_expansion_level, m4_process_macro): Moved...
* m4/macro.c (expansion_level, process_macro): ...to here, and
made static.
* m4/m4module.h (program_name): Not used by modules at all, so
moved...
* src/main.c (program_name): ...to here.
(print_program_name): Renamed...
(print_program_name_CB): ...to conform to the STYLE guide.
2003-07-23 Gary V. Vaughan <gary@gnu.org>
More refactoring of the m4module.h API. Replace #defines with an
enum, and move non-public functions out of the public API.
* m4/debug.c (stdarg.h, varargs.h): Remove variadic header
inclusion.
* m4/macro.c (stdarg.h): Add ANSI C variadic header.
* m4/debug.c (m4_debug, trace): Moved...

* m4/m4module.h (m4_context_field_table): Add entries for new
debug_file and trace_messages fields.
(M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)

functions, since they are only ever used from this file. Changed
all callers.
2003-07-17 Gary V. Vaughan <gary@gnu.org>
Change the macros for checking syntax so that matching against
multiple possible syntax classes can be done with a single
comparison some of the time. The various classes are now bits of
an int that can be checked with bitwise logic operators.
* m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
(M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
(M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
(M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
(M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)

(M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
(M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
(M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
Replace all calls with invocations of these...
(m4_is_syntax, m4_has_syntax): ...New macros.
* src/freeze.c (produce_syntax_dump): Remove mask argument, which
is no longer required with new macros. Changed all callers.
2003-07-15 Gary V. Vaughan <gary@gnu.org>
* m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
values are returned as part of the internal interface, so they
need to be moved...
* m4/private.h: ...to here.
* m4/macro.c (expand_token): Check for out of range
m4_peek_input() results before looking up in the syntax table.
(collect_arguments): Ditto.

2003-07-08 Paul Eggert <eggert@twinsun.com> and
Gary V. Vaughan <gary@gnu.org>
Conform to POSIX if the POSIXLY_CORRECT environment is set.
--traditional `define' now smashes all the definitions.
* NEWS: Explain this.
* doc/m4.texinfo (Defn): `defn' takes any number of arguments.
(Extensions): Explain that extensions that are incompatible with
POSIX are disabled if POSIXLY_CORRECT is set.

POSIXLY_CORRECT.
(builtin_defn)): Allow any number of arguments.
(builtin_undivert): Do not allow nonnumeric arguments
if POSIXLY_CORRECT.

POSIXLY_CORRECT is set, or if -G is given.
* tests/builtins.at: New test for smashed definitions.
2003-06-27 Gary V. Vaughan <gary@gnu.org>
* doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
* m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
not to slow the parser down.

* m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
variable references in macro expansions.
* doc/m4.texinfo (Eregexp and Regexp): Typo.

(Eval): Typo.
2003-06-26 Gary V. Vaughan <gary@gnu.org>
Move the global variables that pertain to syntax to a new `struct
m4_syntax_table', and then add one of these to `struct m4'. The
ripple effect through the code to both change formerly global
references, and make sure a suitable context is available in
lexical scope is disproportionately large compared to the size of
the change proper. This change is a large part of decoupling
syntax.c from the rest of the code that uses it.
* m4/m4private.h (struct m4): Add a syntax field.
* m4/m4.c (m4_create): Initialise it,
(m4_delete): Recycle it.
(m4_get_symtab): Remove hand coded version...
(m4_get_symbol_table): ...and generate this with cpp. Changed all
callers.
* m4/m4module.h (m4_context_field_table): Add an extra field so we
can generate m4_get_symbol_table. Add a new row for
m4_get_syntax_table.
(M4SYNTAX): Syntactic sugar for module writers.
(m4_symtab): Renamed to m4_symbol_table. Changed all callers.
(m4_syntax_table): New home for syntax related formerly global
variables.
* m4/m4private.h (struct m4_syntax_table): Define it.
* m4/input.c (m4_input_init): Initialisation of these formerly
global variables moved...
* m4/syntax.c (m4_syntax_create): ...to here.
* m4/input.c (m4_input_exit): And similarly, recycling of the
memory used by those values moved...
* m4/syntax.c (m4_syntax_delete): ...to here.
* m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
Moved to m4/m4private.h.
* m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
(m4_get_syntax_bcomm, m4_get_syntax_ecomm)
(m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
(m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
objects. Changed all callers that used to directly access the
global equivalents.
(m4__single_quotes, m4__single_comments, m4__use_macro_escape):
Removed and incorporated into m4_syntax_table structure.
* m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
* m4/syntax.c (m4_set_syntax): Now returns an error status,
instead of requiring a `struct m4' to generate its own errors.
Changed all callers.
* src/main.c (main): Now that the syntax table is initialised as
part of m4_create, we have to manually wipe the syntax entries if
we are about to read a frozen file.
2003-06-26 Gary V. Vaughan <gary@gnu.org>
* doc/STYLE: Added notes on callback naming schemes.
* m4/module.c (m4_set_module_macro_table)
(m4_set_module_builtin_table): Declarations weren't changed when
definitions were renamed on 2003-06-19.
* m4/hash.c (m4_hash_resize): ifdefed out. This function is
neither used nor particularly appropriate since it exposes the
internal workings of the hash module. I haven't yet decided
whether to remove it entirely.
2003-06-20 Gary V. Vaughan <gary@gnu.org>
Two related changes, and a huge knockon effect throughout the
source: Moved the option variables out of global space and into
`struct m4'; made `m4_symtab' a real datatype, so that its api
is not marred passing `struct m4' around just so it can decide
whether to keep traced symbol names or not. Added setters and
getters for the formerly global option variables, and obviously
changed a vast number of functions to take a `struct m4' and use
the getter funcs to find option values.
* m4/utility.c (interactive, sync_output, debug_level)
(no_gnu_extensions, prefix_all_builtins, suppress_warnings)
(max_debug_argument_length, warning_status, nesting_limit)
(discard_comments): Removed.
* m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
(debug_level, max_debug_argument_length, prefix_all_builtins)
(suppress_warnings, discard_comments, interactive, sync_output):
Removed from here...
* m4/m4private.h (struct m4): ...and equivalent fields added to
this structure.
(m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
(m4_get_nesting_limit_opt, m4_get_debug_level_opt)
(m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
(m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
(m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
macros for the new fields.
* m4/m4module.h (m4_context_field_table)
(m4_context_opt_bit_table): Helper macros used to generate
prototypes, setters and getters for new option fields
consistently.
* m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
(m4_get_nesting_limit_opt, m4_get_debug_level_opt)
(m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
(m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
(m4_get_interactive_opt, m4_get_sync_output_opt)
(m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
(m4_set_nesting_limit_opt, m4_set_debug_level_opt)
(m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
(m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
(m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
setter and getter functions generated by cpp from
m4_context_field_table and m4_context_opt_bit_table, exported as
part of the module api. Changed all callers.
* m4/symtab (struct m4_symtab): Used as the concrete type for
m4_symtab now.
(m4_symtab_create): Allocate and initialise a new struct.
(m4_symtab_apply): New function that works like m4_hash_apply, but
with different callbacks specific to symbol tables. Changed all
callers.
(symbol_destroy, arg_destroy, arg_copy): Renamed
symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
they have unused parameters for a reason!
(dump_symbol_CB): New callback to dump the contents of a single
symbol.
(symtob_dump): Rewritten in terms of dump_symbol_CB.
* m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
Changed all callers.
* m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
of the contained `m4_symtab' at the `no_gnu_extensions' field.
Although I'm not convinced these semantics are correct, they are
at least consistent with how things were before this delta. Also
set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
2003-06-19 Gary V. Vaughan <gary@gnu.org>
Tie down the interface to libm4 some more. Make more structures
opaque to modules by moving them to m4private.h, and writing
setters and getters. To win back the speed penalty for doing this
also wrote macroized versions that do know about structure layout
in m4private.h and #include that file into modules when NDEBUG is
defined at compile time. There are still some accessor macros in
m4private.h that need to go, but that is not necessary to clean
the module api up.
* m4/m4module.h (m4_symbol_type): Moved...
* m4/m4private.h (m4__symbol_type): ...to here.
* m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
(m4_set_symbol_traced, m4_set_symbol_name_traced)
(m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
(m4_get_symbol_func, m4_symbol_value_create)
(m4_symbol_value_delete, m4_set_symbol_value_text)
(m4_set_symbol_value_func): New exported api to symbols.
(m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
and m4_is_symbol_value_func.
* m4/m4module.h: Prototype these guys.
* m4/module.c (m4_set_module_macro_table)
(m4_set_module_builtin_table): Make these static, there is no
reason to pollute the api with them.
* m4/m4private.h: Reformatting.
(m4_get_symtab): Only define when NDEBUG is defined.
(m4_get_symbol_value, m4_get_symbol_traced)
(m4_set_symbol_traced, m4_set_symbol_name_traced)
(m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
(m4_get_symbol_func, m4_symbol_value_create)
(m4_symbol_value_delete, m4_set_symbol_value_text)
(m4_set_symbol_value_func): Macro implementations of the new
functions when NDEBUG is defined.
(SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
(SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
Superceded by the above. All callers changed.
(M4ARG): Removed. This is no longer different to the
m4/m4module.h definition.
* modules/gnu.c, modules/m4.c: Only include m4private.h when
NDEBUG is defined. That way we exercise the same (albeit slower)
api that external modules must use.
2003-06-18 Gary V. Vaughan <gary@gnu.org>
Renamed some of the types and their accessors to make more sense.
Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
has a stack of SYMBOL_VALUEs.
* m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
(m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
m4_get_symbol_value_type, m4_get_symbol_value_text,
m4_get_symbol_value_func and m4_symbol_value_copy respectively.
Changed all callers.
(m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
(m4_get_token_type): Renamed
* m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
to the internal api.
* m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
s/TOKEN_/VALUE_/
(m4__symtab_init, m4__symtab_exit): Removed prototypes.
(m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
(m4__token_type): Moved here from m4module.h.
(m4__next_token): Renamed from m4_next_token.
* m4/symtab.c: Removed some of the parameterised macro support
functions for modularisation later.
(m4_token_copy): Renamed to m4_symbol_value_copy, and use new
m4_hash_dup to perform a true deep copy of the SRC.
(arg_copy): Callback for m4_symbol_value_copy.
* utility.c (m4_token_get_type, m4_token_text, m4_token_func):
Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
m4_get_symbol_value_func. Changed all callers.
2003-06-18 Gary V. Vaughan <gary@gnu.org>
Tidy up style of hash.[ch] in accordance with doc/STYLE.
* m4/hash.c: Internal symbol renaming and formatting.
(m4_hash_dup): New function to facilitate deep copies of hash
tables.
(m4_hash_apply_func): Returns a void* now, which is a richer type
for returning exceptions (NULL means keep going).
(m4_hash_apply): Ditto.
* m4/hash.h: Declare exported symbols with an explicit extern.
Reformated.
2003-06-17 Gary V. Vaughan <gary@gnu.org>
Still refactoring furiously. This delta represents a change in
semantics to symtab.c. Instead of building temporary m4_tokens
in the caller, and copying fields in the methods, we now create
the actual m4_token for hashing in the caller so the methods just
slot them in directly. Also, this means that we don't lookup a
symbol and get back an allocated but VOID token to copy fields
into, we create the token we want to push and pass that to
m4_symbol_define or m4_symbol_pushdef. And that's it. There are
a few other small changes to stop knowledge of the implementation
of symtab.c leaking out into other files.
* m4/macro.c (expand_argument): Comment typo corrected.
* m4/symtab.c (symtab_fetch): New function to fetch the address of
an interned symbol.
(m4_symbol_pushdef): Take an extra value parameter and use this
directly as the new top of the value stack. All callers changed
to build a token and pass responsibility for memory in, rather
than copying as we used to.
(m4_symbol_define): Also use the new value parameter directly as a
replacement for the top of the value stack. All callers changed
to build a token as above.
(m4_set_symbol_traced): New function to set the traced bit on the
named symbol, creating it if necessary.
(symbol_popval): The guts of the old m4_symbol_popdef.
(m4_symbol_popdef): Use it.
* m4/builtin.c (m4_symbol_set_token): Removed,
(m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
replaced...
* m4/module.c (m4_set_module_builtin_table)
(m4_set_module_macro_table): ...with these more orthogonal
functions.
* m4/m4module.h (m4_macro_pushdef, m4_macro_define)
(m4_builtin_pushdef, m4_builtin_define): Removed. No longer
required.
* m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
(m4_arg_signature_parse): Moved...
* m4/symtab.c: ...to here.
* m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
screw something up. Moved...
* m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
actually does a proper deep copy of source to dest.
2003-06-16 Gary V. Vaughan <gary@gnu.org>
Further refactoring to stabilise the module API. Renaming some
functions for orthogonality, and judicious definition migration to
move things out of the set of exported symbols.
* doc/STYLE: New file. Notes on coding style.
* m4/m4module.c: Updated bitrotted docucomment at the top of the
file.
(m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
m4_get_module_name, m4_get_module_builtin_table,
m4_get_module_macro_table which are verb phrases. Changed all
callers.
* m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
Moved to...
* m4/module.c (m4_set_module_builtin_table)
(m4_set_module_macro_table): ...here, and renamed. Changed all
callers.
* m4/m4module.c (m4_module_data): This...
* m4/m4private.c (struct m4_module_data): ...and this...
* m4/module.c (module_data) ...consolidated here and no longer
exported. Changed all callers.
2003-06-16 Gary V. Vaughan <gary@gnu.org>
Begin work on lifting the curse of the global variables. To start
with create a `struct m4' context container, and replace
`m4__symtab' with `context->symtab' throughout. This means
initialising a context container in main, and adjusting many
functions between main and the module entry points so that the
container gets passed through. It would have been nice to
defer this until after 1.5, but it has a major effect on the
user's module writing ABI, so it needs to be addressed now - at
least in the areas that impact the ABI. An interrelated change
in the symtab API removes the dependency on a global symbol table,
and instead focuses on a passed table (from the context
container).
* TODO: Reminders for finishing context functionality.
* m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
* m4/m4.c: New file. Manage new struct m4 objects to eliminate
global variables and eventually allow m4 to be reentrant.
* m4/m4private.h (m4): Define the new structure here...
(M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
don't carry the overhead of a function call.
* m4/m4module.h: Prototype extern functions from m4/m4.c.
(m4): Declare type for new struct m4 objects.
(M4SYMTAB): User macro to ease finding the symbol table for the
current context for module developers.
(m4_symbol_token): Renamed to m4_symbol_set_token which contains a
verb.
(M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
(m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
(m4_call_macro, m4_dump_symbols, m4_expand_input)
(M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
(m4_macro_pushdef, m4_macro_table_install, m4_module_load)
(m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
m4* context parameter. Changed definitions and all callers.
(m4_symtab): Alias for m4_hash to decouple the
m4_symtab api from m4_hash.
(m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
m4_hash.
(m4_symtab_create): New function to return an initialised
m4_symtab.
(m4_symtab_delete): New function to delete an m4_symtab's memory.
(m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
(m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
instead of simply using the global m4__symtab. Changed
definitions and all callers.
* m4/m4private.h (m4__symtab_remove_module_references): Ditto.
* m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
* src/main.c (main): Create a context and use that instead of the
former global m4__symtab.
2003-06-13 Gary V. Vaughan <gary@gnu.org>
* m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
to the callback. Callbacks should not need to hardcode the
hashtable they are working from, nor should we have to waste the
userdata parameter to pass the table in.
* m4/hash.h (m4_hash_apply_func): Require the initial table
parameter.
* m4/symtab.c (symtab_destroy): Use the passed table instead
of hardcoding m4__symtab.
(m4_symbol_popdef): Don't use the userdata parameter to pass the
table to arg_destroy.
(arg_destroy): Use the hash parameter, ignore userdata.
* modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
prototype.
(traceon, traceoff): Call set_trace with the extra initial
parameter.
2003-06-13 Gary V. Vaughan <gary@gnu.org>
More refactoring to stabilise the module api, this time for
symtab.c. Additionally, start to pay attention to function names
that don't contain a verb like they should.
* m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
wrapper for m4_hash_apply to decouple the symtab module from the
hash module.
(m4_symbol_builtin, m4_symbol_macro): Renamed to
m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
callers.
(m4_symbol_delete): Create a macro version to save a function
call.
(m4_token_t, m4_data_t): These violate the POSIX reserved
namespace. Renamed to m4_token_type and m4_symbol_type. Changed
all callers.
(m4_token_type): Renamed to m4_token_get_type.
(m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
(m4_symtab_exit): Removed from the exported module
api...
* m4/m4private.h (m4__symtab, m4__symtab_init)
(m4__symtab_remove_module_references, m4__symtab_exit): ...and
renamed and added to the internal api. Changed all callers.
(m4_symtab_apply): A faster macro version of the function for
users of the internal api.
* m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
symbol_destroy and arg_destroy.
(symtab_debug): Added a prototype.
(m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
so that callers in this file get the faster macro versions from
m4/m4private.h.
2003-06-12 Gary V. Vaughan <gary@gnu.org>
Refactoring modules to rationalise the API into an external
documented (eventually!) API for use by modules in the `m4_'
namespace declared in m4/m4module.h, an internal API between the
source files we ship (including our shipped modules) in the `m4__'
namespace declared in m4/m4private.h and making the rest as
cohesive as possible with liberal use of the `static' keyword.
This change represents an audit to m4/module.c along these
guidelines.
* m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
Removed. No longer used.
(m4_module_close): Removed prototypes.
(m4_module_init, m4_module_open, m4_module_unload_all): Removed
from the exported module api...
* m4/m4private.h (m4__module_init, m4__module_open)
(m4__module_exit): ...and renamed and added to the internal api.
Changed all callers.
(BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
Centralised definitions after renaming...
* m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
(M4_FINISH_SYMBOL): ...and removing from here.
(m4_module_dlerror, m4_module_remove, m4_module_close)
(m4_caller_id): Not exported at all, so renamed to module_dlerror,
module_remove, module_close and caller_id.
(MODULE_SELF_NAME): New macro to make reporting self errors
easier.
(m4_module_load, module_close, module_remove): Use it.
* m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
name.
* src/main.c (main): Use it.
2003-06-12 Gary V. Vaughan <gary@gnu.org>
* README: Remove references to --enable-changeword, which has been
removed from the code.
2003-06-11 Gary V. Vaughan <gary@gnu.org>
Getting rid of the annoying bug with configure --enable-debug,
which spewed -e: command not found errors. This was an interaction
between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
branch-1-5) to get the full fix.
* config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
and then use the probed value of $SED.
(AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
this, it messes up the AC_REQUIRE stack.
2003-06-10 Gary V. Vaughan <gary@gnu.org>
* m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
the destroy callback.
(m4_arg_destroy): Use the hash address to free the hash node key
field.
2003-06-06 Gary V. Vaughan <gary@gnu.org>
First cut at formal parameters in macros.
* configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
* m4/xstrzdup.c: New file.
* m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
associative array of parameter names to details.
(m4_symbol_token): Capture macro names with parameter lists.
(m4_arg_signature_parse): And build an associative array to hang
from the symbol structure to map names to details.
* m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
m4_hash_resize idiom. Now that we potentially add a little hash
table to many of the entries in the symbol table, added an extra
arg to set the initial size. Changed all callers.
(m4_hash_apply): New function that is basically a generalised
version of...
* m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
all callers to call m4_hash_apply instead.
(m4_arg_destroy): Recycle memory used by an m4_token_arg.
(m4_symbol_popdef): Use m4_arg_destroy to help recycle the
m4_arg_signature association that might be attached to the symbol,
* m4/hash.h (m4_hash_apply_func): Replacement type for...
* m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
(M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
parameter lists.
(M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
(M4_IS_IDENT): Detect characters that can be safely used in
parameter names.
* m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
* m4/macro.c: Corrected grammar in some comments. Use `token'
rather than `td' for m4_token variables.
(m4_process_macro): If we find a dollar followed by some
M4_IS_IDENT characters, replace that with the contents of the argv
entry with offset stored in the m4_token_arg associated with the
collected identifier.
2003-06-05 Gary V. Vaughan <gary@gnu.org>
Begin preparations for supporting formal parameters in m4 macros.
* m4/m4private.h (struct m4_token_arg): Placeholder for holding
the details of a formal parameter.
(m4_token): Add an arg_signature member to hold a hash table for
looking up formal parameters.
* m4/input.c: Update more bitrotted comments.
(m4_push_builtin): Initialise arg_signature member.
(init_builtin_token): Copy arg_signature member.
* m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
(m4_macro_pushdef, m4_macro_define): Rewritten as macros to
replace...
* m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
(m4_macro_pushdef, m4_macro_define): ...these, And...
(m4_symbol_token): ...wrapped around this new function, which
vastly simplifies the arguments required by the functions it
replaces.
Changed all callers.
2003-06-05 Gary V. Vaughan <gary@gnu.org>
* m4/macro.c: Format changes.
2003-06-04 Gary V. Vaughan <gary@gnu.org>
* m4/input.c: Updated various bitrotted comments.
(m4_push_builtin): Just pass the whole m4_token, rather than
extracting all the fields in the caller. This also allows us to
check the token type for consistency.
(macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
Renamed to builtin_funcs, builtin_peek, builtin_read,
m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
the code. Changed all callers.
(struct input_block): Similarly renamed u_m member to u_b, and
changed all callers.
(m4_next_token): Use bzero to initialise the data fields.
* m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
2003-05-29 Gary V. Vaughan <gary@gnu.org>
These changes were necessary to get m4 to build on my iBook
running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
(GCC) 3.1 20020420 (prerelease)":
* src/main.c: Don't include dlfcn.h, ltdl.h handles correct
inclusion of module loader headers.
* modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
* m4/Makefile.am: Ditto.
(libm4_la_LIBADD): Added $(LTLIBINTL).
* m4/utility.c (program_name): Removed declaration in favour of
the one already in error.c!

* doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
running m4 itself.
* tests/others.at (iso8859): Use abs_srcdir, not srcdir.
2002-11-04 Akim Demaille <akim@epita.fr>

2002-05-29 Gary V. Vaughan <gary@gnu.org>
Preparations for refactoring syntax tables to allow reverse
lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
speed of normal lookups in an array of unsigned short.
* m4/input.c (single_quotes, single_comments, use_macro_escape):
Moved from here...
* m4/m4private.h (m4__single_quotes, m4__single_comments,
m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
is for internal symbols which unavoidably pollute the global
namespace, but are not published APIs.
Adjusted all callers.
* m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
m4_set_comment, m4_set_syntax, set_syntax_internal,
unset_syntax_attribute): Moved from this file...
* m4/syntax.c: New. ...to this file.
Also added an m4_syntax_exit stub for orthogonality.
* src/main.c (main): Use it.
* m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
* m4/m4module.h: Reformatting. New prototypes.
2002-05-29 Gary V. Vaughan <gary@gnu.org>
* bootstrap (aclocal_apiversion): The aclocal apiversion is
distinct from the automake release number (in that the apiversion
apparently has no micro-version-component).
(aclocal_apilibdir): Use it.
2002-05-28 Gary V. Vaughan <gary@gnu.org>
* m4/hash.c (m4_hash_resize): New function.
* m4/hash.h: Add prototype.
* m4/symtab.c (m4_symtab_init): Use it. This could do with some
benchmarking to find a good value for, say, autoconf. This is
already a little quicker than before for me.
* m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
* m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
and reenamed.
* m4/hash.h: Adjust prototypes.
2002-01-22 Akim Demaille <akim@epita.fr>
* bootstrap (aclocal_apilibdir): New, to cope with Automake's new
APIVERSION scheme.
* tests/Makefile.am (package.m4): New.
* tests/atlocal.in: Adjust to CVS Autotest.
* config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
* configure.ac: LIBOBJ is a forbidden string.
Simplify AM_INIT_AUTOMAKE invocation.
* config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
options.m4.
2002-01-21 gettextize <bug-gnu-utils@gnu.org>
* po/Makefile.in.in: Upgrade to gettext-0.10.40.
2001-10-19 Akim Demaille <akim@epita.fr>

not closed.
2001-10-19 Akim Demaille <akim@epita.fr>
* m4/macro.c (expand_argument): Display where was opened what is
not closed.
2001-10-18 Akim Demaille <akim@epita.fr>
* m4/input.c, modules/m4.c: Formatting changes.
2001-10-17 Gary V. Vaughan <gary@gnu.org>
* bootstrap: s/configure.in/configure.ac/
2001-10-16 Gary V. Vaughan <gary@gnu.org>
* m4/symtab.c (m4_symbol_destroy): This function calls
m4_symbol_popdef, which recycles a symbols memory when the last
definition is popped. Since we were passing the address of the
symbol name found in the symbol table, and it was being removed
partway through m4_symbol_destroy() we were referencing freed
memory for the balance of the function. Now we take a copy of the
symbol name tring and use that as a key into the symbol
table... that way if the original symbol name is freed, the copy
is still valid.
2001-10-13 Akim Demaille <akim@epita.fr>
* m4/ltdl.c: Update.
2001-10-13 Akim Demaille <akim@epita.fr>
* src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
Don't gettextize internal error messages.
2001-10-13 Akim Demaille <akim@epita.fr>
* tests/macros.at (Arity and defn): New failing test.
(Arity, defn, and freeze): New.
Fix `Arity and defn'.
* m4/input.c (m4_push_macro): Don't forget the arity.
* modules/m4.c (defn): Likewise.
2001-10-13 Akim Demaille <akim@epita.fr>
* tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
to...
* tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
(Propagation of traceon, Propagation of --trace): this new file.
2001-10-13 Akim Demaille <akim@epita.fr>
* m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
interface instead of (name, argc...).
Upon failure, specify which argument was guilty.
Adjust callers.
2001-10-13 Akim Demaille <akim@epita.fr>
* modules/evalparse.c: Save translators' time: don't translate
internal error messages.
(m4_evaluate): Simplify/normalize error messages.
* doc/m4.texinfo (Eval): Adjust.
2001-10-13 Akim Demaille <akim@epita.fr>
* m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
where no checking is needed.
* m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
interface instead of (name, argc...).
Adjust callers.
* modules/gnu.c (m4_patsubst_do): Don't check argc, done
elsewhere.
2001-10-13 Akim Demaille <akim@epita.fr>
* m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
exclude the builtin name from the count.
* modules/m4.c (ifelse): Do not use the regular argc mechanism, as
calling ifelse with a single argument is valid.
* doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
with 1 and 2 args, mostly to strengthen the test suite.
2001-10-13 Akim Demaille <akim@epita.fr>
* m4/output.c (m4_make_diversion, m4_insert_file)
(m4_insert_diversion, +m4_freeze_diversions): Ansify.
2001-10-12 Gary V. Vaughan <gary@gnu.org>
* m4/input.c (init_builtin_token): Renamed from init_macro_token,
since we call these things builtins in the rest of the code!
* modules/gnu.c (m4_regexp_compile): s/%0/%s/
2001-10-12 Gary V. Vaughan <gary@gnu.org>
Rather than forcing each builtin definition to manage its own
argument range checking, tabulate the maxima and minima for all
builtins in each module. This forces us to consider what the
valid ranges for each builtin should be, and moves the checking
code out of each builtin implementation and into the builtin
caller infrastructure.
* m4/m4module.h (struct m4_builtin): Add argument minima and
maxima.
* m4/m4private.h (struct m4_token): Reflect them here too.
* m4/input.c (struct input_block): ...and here.
(m4_token_copy): New function for token copying.
(init_macro_token): Copy them from a token to the input stack.
(m4_next_token): Don't forget to initialise them for text
macros.
* m4/macro.c (expand_argument): Use m4_token_copy, and also
check argument counts before calling the builtin handler.
* m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
(m4_symbol_macro): Likewise.
* m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
parameters. Updated all callers.
(m4_builtin_define): Ditto.
(m4_macro_pushdef, m4_macro_define): Ditto.
* m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
* modules/evalparse.c: Declare argument counts for defined
builtins and remove explicit calls to m4_bad_argc().
* modules/gnu.c: Ditto.
* modules/load.c: Ditto.
* modules/m4.c: Ditto.
* modules/modtest.c: Ditto.
* modules/mpeval.c: Ditto.
* modules/perl.c: Ditto.
* modules/shadow.c: Ditto.
* modules/stdlib.c: Ditto.
* modules/time.c: Ditto.
* TODO: Updated.
2001-10-10 Gary V. Vaughan <gary@gnu.org>
The trace semantics now attach the trace bit to a symbol name.
For as long as a traceon(`foo') is active, calls to foo will be
traced regardless of intervening undefines or module unloads.
Fixed the flag propogation issues differently to the fixes
reverted with the last attempt at nailing down trace:
* m4/m4private.h: This file is not visible outside of the m4
source tree, so I removed all the `M4_' and `m4_' prefixes to save
on typing. Updated all clients.
(m4_token): New typedef contains the fields that need to be passed
around with the low level tokeniser.
(m4_token_data): Removed.
(m4_symbol): Now contains the traced flag again.
* m4/symtab.c: Rewritten again. Now we don't remove symbols with
the trace bit set. This change is contained entirely within this
module and doesn't leak out into the callers. Updated all
clients.
(m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
new fields in m4_token. Updated all clients.
* m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
that `groks_macro_args' and `blind_if_no_args' flags are retained
when defn() results are passed around in m4 code. Updated all
callers.
(m4_builtin_define): Ditto.
(m4_macro_pushdef, m4_macro_define): Ditto.
* m4/input.c (struct input_block): Add a flags field to facilitate
the above.
(m4_push_macro): ...use it.
(init_macro_token): Retrieve it.
(m4_next_token): Initialise it.
* m4/macro.c (expand_argument): Copy it.
* m4/m4module.h: Adjust.
* tests/builtins.at: Adjust the expected output of the trace
tests to reflect the change in semantics.
* tests/modules.at (modules: trace): Check that unloading a
module which supplies a traced symbol definition doesn't lose te
trace bit.
2001-10-07 Gary V. Vaughan <gary@gnu.org>
* modules/gnu.c (m4_macro_table): Display the timetamp when
expanding __m4_version__.
* configure.ac (--with-modules): Forgot a comma in the
AC_HELP_STRING parameter list.
2001-10-05 Gary V. Vaughan <gary@gnu.org>

* tests/others.at: Use it.
* config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
variable in shell scripts, one uses `$'...
2001-10-04 Gary V. Vaughan <gary@gnu.org>
* configure.ac: `rm -f $m4_getopt_h' was lost.
2001-10-04 Gary V. Vaughan <gary@gnu.org>
* configure.ac (TIMESTAMP): Display with AS_BOX at configure
time. Define it for config.h in order to...
* src/main.c (main): ...display the timestamp for --version.
2001-10-04 Akim Demaille <akim@epita.fr>
* modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
previous builtins `regexp' and `patsubst'.
(regexp, patsubst): Use them.
(eregexp, epatsubst): New builtins.
* doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
(Epatsubst and Patsubst, Eregexp and Regexp): these.
(Extensions): More info on REs.
2001-10-04 Akim Demaille <akim@epita.fr>
* modules/modtest.c (init_handler): Consistently output to stderr.
(finish_handler): New.
(test): The `if' is an `assert'.
* tests/modules.at: Adjust.
2001-10-04 Akim Demaille <akim@epita.fr>
* m4/utility.c (m4_bad_argc): Detail the mismatches.
2001-10-01 Akim Demaille <akim@epita.fr>
* tests/generate.awk: Tag the tests with `documentation'.
* tests/modules.at (AT_CHECK_M4_MODTEST): New.
Use the make the existing modtest tests more uniform, and complete
the set of possibilities.
2001-10-01 Akim Demaille <akim@epita.fr>
* config/gmp.m4: Consult the user before using GMP: use
--without-gmp.
* configure.ac: Adjust.
* modules/gmp.c: No protection needed as the module is not built
if GMP is not used.
2001-10-01 Akim Demaille <akim@epita.fr>
* tests/generate.awk: Remove debugging code.
(fatal): Specify the current location.
* m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
* modules/gnu.c, modules/m4.c: Use M4ARG.
2001-10-01 Akim Demaille <akim@epita.fr>
* modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
(m4_regexp_compile): New.
(regexp, patsubst): Use it.
2001-09-30 Gary V. Vaughan <gary@gnu.org>
Reinstate the memory handling improvements from the patch I just
reverted. Relevant ChangeLog entries repeated here:
* m4/module.c (m4_module_remove): New function that holds the core
of the old m4_module_unload.
(m4_module_unload): Use it.
(m4_module_unload_all): When we know the modules will never be
used again (i.e. on exit), free up as much module memory as
possible. There are still some artifacts from resident modules
living inside ltdl.c, but everything else is freed.
* m4/debug.c (m4_debug_exit): Free memory allocated in
m4_debug_init().
* m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
* m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
* src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
* m4/m4module.h: Updated prototypes.
* m4/hash.c (m4_hash_exit): Free the nodes on the free list.
* m4/hash.h: Updated prototypes.
* src/main.c (main): Use all these new functions to clean up as
much memory as possible before exit.

Reverted my large patch for removing the old m4_symbol
structure on 2001-09-20. We are still not happy about the way
trace works in conjunction with defn and undefine, and leaving
the reverted patch active prevents us from moving the traced
bit from the definition back to the symbol.
2001-09-30 Gary V. Vaughan <gary@gnu.org>
* configure.in: Moved to...
* configure.ac: ...here. Added a libtool like timestamped
banner, and tidied up the libltdl cruft.
* config/mkstamp: Script to extract a timestamp from ChangeLog.
* modules/Makefile.am (INCLTDL): Removed. This is required
only when libltdl is configured in a subdirectory.
* src/Makefile.am: Ditto.
(LIBADD_DL): No need to add this again, libtool already knows
that libm4.la depends on it.
* m4/Makefile.am: Automake sets variables from AC_SUBST. Use
them.
* TODO: stackovf.c is basically broken.
Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
2001-09-28 Akim Demaille <akim@epita.fr>
* tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
2001-09-27 Akim Demaille <akim@epita.fr>
* tests/m4.in: Don't use short options.
Simplify the stderr signature normalization.
2001-09-27 Akim Demaille <akim@epita.fr>
tests/m4 shall be position independent.
* tests/m4.in: New.
* tests/m4: Remove.
* tests/testsuite.at: No args to AT_INIT.
* configure.in, tests/Makefile.am: Adjust.
2001-09-22 Akim Demaille <akim@epita.fr>
Autotest has changed again.
* tests/Makefile.am (DISTCLEANFILES): Add package.m4.
(package.m4): Remove.
* configure.in: Adjust to LIBADD_GMP.
2001-09-21 Gary V. Vaughan <gary@gnu.org>
* config/gmp.m4 (AC_ARG_WITH): Removed.
(GMP_LIB): Renamed to LIBADD_GMP for consistency.
(AC_LIB_GMP): When performing a test compile against libgmp,
include the header gmp.h if possible, and link against -lgmp. If
they both work define USE_GMP.
* modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
(mpeval_LTX_init_func): Complain on load that there was no libgmp
at compile time.
2001-09-20 Gary V. Vaughan <gary@gnu.org>
* m4/evalparse.c: Moved to...
* modules/evalparse.c: ...here. This code is shared between
modules/mpeval.c and modules/m4.c, so there is no need to pollute
the libm4 API with its details. Moderately rewritten to interface
into its clients more simply.
* m4/eval.c: Deleted. Migrated functionality to...
* modules/m4.c: ...here.
(builtin_eval): Implemented in terms of the new interface style.
* modules/mpeval.c (builtin_mpeval): Ditto.

(AC_LIB_GMP): this.
By default, use gmp.
Massive revamping.
* configure.in: Adjust.
Use Automake conditionals for USE_GMP.
Always compute sizeof (long long int).
This was a bug BTW, as `eval' (not `mpeval') depends on it:
before, it was used _only_ if mpeval was not activated.
* modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
(mpeval_la_LIBADD): New macros.
* modules/mpeval.c: No longer be conditioned by WITH_GMP.
Indent.
* tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
* tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
WITH_GMP.
2001-09-20 Akim Demaille <akim@epita.fr>
* tests/Makefile.am (package.m4): New.
* tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.

More cleanup. After the last patch, m4_symbol holds nothing but
the head of a chain of m4_token_data. So I have removed the old
m4_symbol, so that m4_token_data chains are stored directly in the
value cell of a hash table node. But there's more... m4_symbol
was a more natural name for the symbol value cell, and now that it
is gone I have renamed the former m4_token_data structure to
m4_symbol. This change turned out to be a pig to get right, since
the original code didn't need to modify the value cell itself,
since changing the chain happened inside the m4_symbol that used
to be returned -- I had to pass the address of the value cell
across various function calls, incase the head value changed. I
also tightened up the memory management to help me find a nasty
memory corruption bug that took me all night to track down...
* m4/m4private.h (struct m4_symbol): Removed.
(struct m4_token_data): Renamed to `struct m4_symbol'. Updated
all references.
* m4/hash.c (m4_hash_iterator_value): Return the address of the
value cell. Updated all callers.
* m4/symtab.c: Took advantage of the simplification in the data
structures to rewrite a lot of this file more simply. There is
still some room for optimisation here, but we should tackle that
systematically closer to the release.
* m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
revealed. This version is ahead of CVS libtool until I get chance
to flush my changes.
* m4/module.c (m4_module_remove): New function that holds the core
of the old m4_module_unload.
(m4_module_unload): Use it.
(m4_module_unload_all): When we know the modules will never be
used again (i.e. on exit), free up as much module memory as
possible. There are still some artifacts from resident modules
living inside ltdl.c, but everything else is freed.
* m4/debug.c (m4_debug_exit): Free memory allocated in
m4_debug_init().
* m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
* m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
* src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
* m4/m4module.h: Updated prototypes.
* m4/hash.c (m4_hash_exit): Free the nodes on the free list.
* m4/hash.h: Updated prototypes.
* src/main.c (main): Use all these new functions to clean up as
much memory as possible before exit.
2001-09-18 Gary V. Vaughan <gary@gnu.org>
The `traced' flag needs to be attached to the definition of a
symbol rather than the current symbol containing the definition.
Implementing this showed up some long standing post 1.4 bugs in
flag propogation which I also fixed.
* m4/m4private.h (struct m4_symbol): Remove the traced flag.
(struct m4_token_data): And add it back in here.
* m4/input.c (init_macro_token): Propogate the traced flag
correctly.
* m4/macro.c (expand_argument): Ditto.
* tests/builtins.at (trace2, trace3): New tests based on Akim's
sadistic email ;-)
2001-09-08 Gary V. Vaughan <gary@gnu.org>
* m4/m4private.h (struct m4_token_data): Simplified by removing
the redundant `traced' flag, and one level of structure nesting.
(M4_TOKEN_DATA_FUNC_TRACED): Removed.
* m4/input.c (init_macro_token): No need to initialise removed
`traced' field.
* m4/macro.c (expand_argument): No need to copy it either.
* m4/utility.c (m4_token_data_func_traced): Or provide an access
function.
* m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
dependant on multiple symbols with the same key, so preserving
relative symbol order in each bucket during resizing is no longer
required. The resize function is considerably faster as a result.
* m4/m4module.h, m4/builtin.c, m4/symtab.c:
s/m4_symbol_insert/m4_symbol_define/g;
s/m4_builtin_insert/m4_builtin_define/g;
s/m4_macro_insert/m4_macro_define/g. Updated all callers.
2001-09-08 Gary V. Vaughan <gary@gnu.org>
Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
commits, the m4_lookup_symbol dispatch function is split into
specialised functions that must be called directly.
* m4/m4module.h (m4_symbol_lookup_t): Removed.
* m4/symtab.c (m4_lookup_symbol): Removed.
(m4_symbol_builtin, m4_symbol_macro): New functions.
* m4/builtin.c (m4_builtin_define): Split into...
(m4_builtin_pushdef, m4_builtin_insert): ...these.
(m4_macro_define): Split into...
(m4_macro_pushdef, m4_macro_insert): ...these.
* src/main.c (main): Set command line macros from `-D' parameters
using `m4_macro_define'.
2001-09-08 Gary V. Vaughan <gary@gnu.org>
* m4/symtab.c (m4_symtab_remove_module_references): Renamed as
this from m4_remove_table_reference_symbols().
* m4/m4module.h, m4/module.c: Updated all references.
2001-09-07 Akim Demaille <akim@epita.fr>
* modules/stdlib.c, modules/times.c: Misc cleanups.
2001-09-07 Akim Demaille <akim@epita.fr>
* configure.in: We now need Autoconf 2.52e.
* m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
and `M4_SYMBOL_DELETE'.
* m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
* src/main.c (main): Adjust.
2001-09-06 Gary V. Vaughan <gary@gnu.org>
Fix the obstack.h problem once and for all! At configure time we
can test for a system supplied obstack.h: depending on the
result, we now generate system.h with an #include of the correct
header. As a bonus, I've also added a --with-included-obstack,
incase the user doesn't like the system obstack for some
reason... and also we can test the shipped obstack on a system
that has oe of its own. We also now need to be careful to add
build directories to the include search path, since the generated
system.h will be in the build tree.
* configure.in (AC_CONFIG_FILES): Generate system.h from
system-h.in.
* config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
include the system obstack header or the copy shipped with M4.
Allow the user to override configure and force the build to use
the shipped version.
* m4/system-h.in: New file, template for...
* m4/system.h: ...this. Now deleted.
* m4/m4module.h: Include system.h before everything else.
* src/freeze.c: Ditto.
* m4/Makefile.am (dist-hook): Remove generated system.h.
(INCLUDES): Check builddir for generated headers before checking
srcdir.
* modules/Makefile.am (INCLUDES): Ditto.
* src/Makefile.am (INCLUDES): Ditto.
2001-09-05 Gary V. Vaughan <gary@gnu.org>

2001-09-05 Akim Demaille <akim@epita.fr>
* src/main.c (main): Standardize --version.
2001-09-05 Akim Demaille <akim@epita.fr>
* modules/format.c (format): Have a bigger `str'.
2001-09-05 Akim Demaille <akim@epita.fr>
Rationalize warnings, reporting the macro name as if it were a
program name, and assertions.
* m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
(M4WARN): New.
* m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
(m4_symbol_delete):
Use assert for internal errors.
* m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
M4WARN.
* modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
M4WARN and assert.
* tests/builtins.at (pushpop): Adjust.
2001-09-05 Akim Demaille <akim@epita.fr>
* m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
with pointers.
2001-09-05 Akim Demaille <akim@epita.fr>
* m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
* m4/macro.c, m4/symtab.c: Adjust.
2001-09-05 Akim Demaille <akim@epita.fr>
* m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
(m4_symbol_pop, m4_symbol_del): this.
(m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
(m4_symbol_popdef, m4_symbol_delete): New.
(m4_lookup_symbol): Adjust.
* m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
2001-09-05 Akim Demaille <akim@epita.fr>
* m4/m4module.h (m4_symbol_lookup): Rename as...

unused.
* m4/symtab.c (m4_lookup_symbol): Adjust.
2001-09-03 Gary V. Vaughan <gary@gnu.org>
Bootstrap will now work with Libtool 1.4.1 or higher:
* bootstrap: Remove stale autom4te.cache files when
rebootstrapping.
* config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
libtool.m4.
* bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
libtool.m4 directly.
Run libtoolize to refresh ltmain.sh.
* config/ltmain.sh: Deleted.
* acinclude.m4: Deleted.
* m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
* config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
implementation for the cvs impaired libtool user.
2001-09-03 Akim Demaille <akim@epita.fr>
* m4/symtab.c (m4_lookup_symbol): Give more details when reporting
internal errors.
Avoid using `default' in switch, as it hides useful compiler
warnings when a case is forgotten.
2001-09-03 Akim Demaille <akim@epita.fr>
* src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
is no such thing as `WITH_MODULES'.
2001-09-03 Akim Demaille <akim@epita.fr>
Improve the test suite's selfcontainedness.
* doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
(Include, Undivert): Tag the other input files.
* tests/generate.awk: Catch `@comment file:'.
`-I $src' is no longer needed.
`next' is really like `return': the rest is skipped.
Adjust to `input.m4'.
(fatal): New function.
* tests/foo, tests/incl.m4: Remove.
2001-09-01 Gary V. Vaughan <gary@gnu.org>
The shadowing mechanism and, infact, the whole symbol table
implementation was creaking under the weight of the features piled
on top of it. We now have a separate hash table module which will
dynamically resize to keep symbol density withing good performace
limits, and a new symtab module layered above it. Symbol lookups
are now marginally more efficient (since the shadowed flag is no
longer required) and symbol removal, such as on module unload, is
considerably faster due to a reorganisation of the data structures
used in symtab.c.
* src/main.c (main): Don't mention `-H'.
* doc/m4.texinfo (Invoking m4): Document that -H no longer has any
effect.
* NEWS: Updated.
* m4/hash.c: New generalised dynamic hash table data structure
management module.
* m4/hash.h: Public interface.
* m4/Makefile.am (pkginc_HEADERS): Add hash.h.
(libm4_la_SOURCES): Add hash.c.
* m4/symtab.c: More or less rewritten from scratch, within the
bounds of the previous API.
(m4_symtab_apply): A cleaner version of the old hack_all_symbols
call. Updated all callers.
* m4/m4module.c: #include <m4/hash.h>, and changed all affected
declarations to reflect API changes.
(M4INIT): Generate a declaration too, to avoid the warning with
--enable-debug builds.
(M4FINISH): Ditto.
(HASHMAX): Removed.
* m4/utility.c (hash_table_size): Removed.
(m4_dump_symbols): Rewritten to build and qsort an array of symbol
names, which are then looked up by builtin_dumpdef() as necessary.
This implies a small speedup in builtin_symbols(), which discarded
all of the symbol info under the old call.
* m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
shadowing is implicit in respect to the new data structures.
symbol names are no longer duplicated here, they are stored in the
key field of the hash table.
Moved macro_args and blind_no_args...
(m4_token_data): ...to here.
m4/macro.c (expand_macro): Added a name argument since the symbol
name is no longer copied into each struct m4_symbol. Modified all
callers.
(collect_arguments): Ditto.
* modules/m4.c (set_trace): Ditto.
* modules/gnu.c (builtin_symbols): Updated.
* src/freeze.c (produce_symbol_dump): Much improved in light of
the improved symbol table layout.
2001-09-01 Gary V. Vaughan <gary@gnu.org>
* m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
to M4_SYMBOL_NEXT.
(SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
(SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
SYMBOL_HANDLE): Ditto.
* m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
modules/gnu.c, modules/m4.c, src/freeze.c,
src/main.c: Updated all references.
* src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
Automake 1.5 chokes on dynamic source file lists, Besides, it is
already listed in m4_LDADD... how did that ever used to work?
* configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
link.
* config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
Suggested by Tim Van Holder <tim.van.holder@pandora.be>
* tests/m4: Don't call the m4 wrapper script with libtool, it
works fine all by itself.
2001-08-30 Gary V. Vaughan <gary@gnu.org>
The experimental `changeword' feature never took off, and has
no obvious advantages over `changesyntax' to compensate the
enormous speed penalty it carries:
* configure.in (ENABLE_CHANGEWORD): Removed.
* m4/m4module.h (m4_set_word_regexp): Removed.
* m4/m4private.h (m4_token_data): Removed original_text field.

This also help having a single list of m4 files: in
config/Makefile.am.
* config/Makefile.am (STANDARD_MACROS): Rename as...
(ACLOCAL_MACROS): this.
(list-standard-macros): Remove.
(spy): New.
2001-08-29 Gary V. Vaughan <gary@gnu.org>
In an attempt to moderate my egomania...
* tests/modules.at: Remove attributions.
* tests/generate.awk: When making substitutions to "@&t@", either
"&" or "\&" in the substitution string argument to gsub refer back
to the matched text. "@\\&t@" seems to work though, Tests 43 and
67 now pass for me.
2001-08-29 Akim Demaille <akim@epita.fr>
* tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)

handle that.
* tests/others.at (wrap): Inline wrap.m4.
(shadow): Inline shadow.m4.
(iso8859): Don't specify the path from top_srcdir, but from srcdir.
* tests/m4: Simplify.
2001-08-29 Akim Demaille <akim@epita.fr>
* tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
--language.
2001-08-29 Akim Demaille <akim@epita.fr>

2001-08-27 Akim Demaille <akim@epita.fr>
* tests/Makefile.am (installcheck-local): Don't use
`dc_install_base' which is not visible here, but `exec_prefix'
which is clearly the RT anyway.
* tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
related to testing a now installed m4.
* tests/m4: Do it here.
2001-08-27 Akim Demaille <akim@epita.fr>

* tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
the test suite.
Prefer options over envvars.
* src/main.c (main): First bug caught by the test suite (yeah!):
--batch lacked a `break' which resulted in an accidental
invocation of --discard-comments.
2001-08-27 Akim Demaille <akim@epita.fr>
* tests/others.at (capitalize, changeword, comments, ddivert)
(debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
(misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
(sysv-args, trace, translit, undivert): Don't rely on files in
examples/: AT_DATA them.
2001-08-27 Akim Demaille <akim@epita.fr>
Let the test suite use a wrapper around the not installed m4 to
pretend it is (installed).
* bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
such a way that m4 does not process them.

Don't use aclocal: it's written by hand.

aclocal.
* bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
until it reads the traces by itself.

AC_CONFIG_TESTDIR instead of AT_CONFIG.
Catch unexpanded `jm_' macros.

2001-08-20 Gary V. Vaughan <gary@gnu.org>
Ansify the source. Previously we had a mix, where my code was
in a K&R compatible style, and the preexisting code was in ANSI
style. Nothing is lost wrt release 1.4 by reverting to ANSI,
and now the code base is much cleaner.
* m4/system.h: Remove M4_PARAMS macro and all users. Remove
VOID macro and all users.

variable against `yes'.

place.
2001-08-20 Akim Demaille <akim@epita.fr>
* m4/utility.c (m4_numeric_arg): Spell out the culprit.
* modules/m4.c (undivert): Disable the possibility of undiverting
several files at once: it is not documented, it is inconsistent
with the other macros, it can be straightforwardly mocked by
several invocations, and most importantly, it prevents the
possibility of other kinds of extension.
Use `m4_numeric_arg'.
2001-08-20 Akim Demaille <akim@epita.fr>
* examples/include.m4: Typo.
* tests/generate.awk: Really add it.
* tests/Makefile.am: Adjust.
* tests/others.at (Discard comments): It sure fails without `-c'.
(include, undivert): Add -I examples/.
2001-08-20 Akim Demaille <akim@epita.fr>
Use sprintf, not ecft and friends since it is standard, portable,
simplifies the code, and since the latter is even deprecated
according to the GNU libc documentation.
* modules/format.c: Drop evct support.
2001-08-19 Gary V. Vaughan <gary@gnu.org>
* config/debug.m4 (M4_AC_CHECK_DEBUGGING): Cleaned up. Don't test
for `-pipe' here...

(generate.at): Install a temporary hack until the actual
generate.awk is added to the repository.

2001-08-17 Akim Demaille <akim@epita.fr>

2001-08-17 Akim Demaille <akim@epita.fr>

2001-08-17 Akim Demaille <akim@epita.fr>
Drop Autoconf 2.13 compatibility.
* configure.in (changeword): No need to undefine it, as anyway if
it's defined, M4sugar moved it as m4_changeword.
And anyway, proper quotation is enough.
(m4_pattern_allow): As it exists in 2.50, just use it.
(AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.
Don't handle Gettext's duties, let it handle them.

2001-08-16 Gary V. Vaughan <gary@gnu.org>
m4_modules are no more, we use lt_dlhandles directly and let
latest libltdl features manage the list of loaded modules.
* acinclude.m4: Regenerated.
* m4/ltdl.c: Updated from master copy.
* m4/module.c: Reimplemented to take advantage of advances in
libltdl.

respectively.
(M4INIT_HANDLER): Clean way to declare init functions in modules.
(M4FINISH_HANDLER): And similarly for finish functions.

-- Add indirection to the CONC macro so that arguments are
correctly expanded.
* modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
* modules/shadow.c (m4_init_module): Ditto.
Due to new init function semantics, be careful to perform the
initialisation only on first load.
* modules/perl.c (m4_init_module): Ditto. And Ditto.
(m4_finish_module): Replaced with M4FINISH_HANDLER.
Due to new finish function semantics, be careful to perform the
finalisation only on first load.
* m4/m4private.h (m4_module): Removed in favour of...
(m4_module_data): ...structure without all the wrapper fields.
Instances of this new structure are stored associated lt_dlhandles
with lt_dlcaller_data_set().
* m4/builtin.c (m4_builtin_define): Takes a handle argument
instead of the old module argument.
(m4_builtin_table_install): Ditto.

* m4/m4private.h (m4_token_data): Add a handle field. This
eliminates many of the searches to find the handle associated with
various tokens that are passed between functions.
(struct m4_symbol): Removed the module field. The
module association does not belong with the symbol...
* m4/input.c (struct m4_builtin): ...it belongs with the builtin
that the module implementation code is from. Added a handle
field.
(m4_push_macro): Add a `handle' argument. Changed all callers.

shell variable m4_cv_func_obstack_h.
* tests/defs (M4): Be more careful about relative path to libtool

Allow the tokens `m4_cv_*', `m4_top_srcdir', and `m4_getopt_h'.
Undefine `changeword' only if defined.
* config/gnu-obstack.m4: Require Autoconf 2.52.
(M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.

2000-11-29 Gary V. Vaughan <gary@gnu.org>
Consolidate the myriad of dispersed test scripts into the

Move the implementation of GMP support for the mpeval() builtin
into a loadable module that depends on libgmp. mpeval() and
eval() share a common parser, now in m4/evalparser.c; the code
in m4/numb.c and m4/numb.h is now physically split between
m4/eval.c (the eval() backend) and modules/mpeval.c (the
mpeval() backend), rather than being differentiated by cpp
macros and multiple inclusion. The mpeval module is always
built but will generate an diagnostic if it is used from an
installation that didn't link in the gmp library.
* modules/Makefile.am: build and install the new mpeval module.
* modules/mpeval.c: Now contains the former parts of m4/numb.c
and m4/numb.h that are required for gmp support in mpeval().
* m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
* m4/evalmp.c: Removed.
* m4/m4module.h: Removed conditional prototype for
m4_mp_evaluate().
* m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
and m4/numb.h that do not rely on gmp.
* m4/evalparse.c: New file, contains the shared parts of the
eval() and evalmp() parser implementations, and is no longer
unencumbered by cpp magic to uncover the right parts.
* m4/numb.h: Removed. It's former contents are split between
m4/eval.c and modules/mpeval.c.
* m4/numb.c: ditto.
* tests/other-tests/changeword.test: New test. Rudimentary
testing of changeword builtin runs only if --wnable-changeword
was used at configure time.
* tests/mkconfig.sh: Solaris sed (at least) does not parse nested
alternation correctly. Split into two expressions to compensate.
* m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
* modules/Makefile.am: Build changeword module.
* modules/changeword.c (m4_macro_table): Define __m4_changeword__
only when --enable-changeword was passed to configure.
(builtin_changeword): If --enable-changeword was not used, then
report that changeword() builtin has no support in m4 binary.
2000-11-28 Gary V. Vaughan <gary@gnu.org>
* src/main.c (main): Fixed a particularly nasty bug is
user_search_path setting -- the -M flag processing must be
extremely careful with search path ordering, or else the default
installed module directory (possibly containing modules from a
previous release) is placed earlier in the search path than any -M
arguments (which are relied upon to load uninstalled modules with
most of the tests in the regresion suite).
* modules/load.c (builtin_load): Nasty hack to prevent adding
symbols to symtab again if a module is loaded more than once.
* modules/m4.c (builtin_ifelse): removed unused variable argv0.
* m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
possible NULL pointer dereference.
* m4/module.c (m4_module_find_by_modname): Renamed from
m4_module_modname_find. Fixed all references.
(m4_module_find_by_builtin): New function.
* modules/modfreeze.test: load the `load' module with each
invocation.
* src/freeze.c (produce_frozen_state): Simplified in light of
module field in m4_symbol. Allow a third argument for text macros
to name the originating module.
(reload_frozen_state): ditto.
* m4/m4module.h: Fixup prototypes.
* m4/builtin.h (m4_builtin_define): Add a module argument so
that symbols can be registered against the defining module.
(m4_macro_define): ditto.
* m4/m4private.h (m4_symbol): Make the module field const to save
on casting in the rest of the code.
(SYMBOL_MODULE): New macro.
* m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
symbol reference maintenance bugs when removing a symbol from the
symtab.
* src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
2000-11-27 Gary V. Vaughan <gary@gnu.org>
* configure.in (m4_cv_func_obstack): A better check for whether
libc has an obstack implementation.
* m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
* configure.in (--with-modules): Changed semantics. This
option is now used to list modules to be preopened.
* src/m4.h: #include "ltdl.h" unconditionally.
* src/main.c: Removed all dependencies on WITH_MODULES.
* src/freeze.c: ditto.
* modules/Makefile.am: ditto.

* modules/modtest.test: ditto.
* modules/shadow.test: ditto.
* modules/unload.test: ditto.
* m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
comes up on demand in LTLIBOBJS now.
* configure.in (getopt_long): Creating and relying on a link for
getopt.h on hosts with no getopt_long() of thier own works
correctly now. This is necessary so that callers of getopt_long()
can simply `#include <getopt.h>': the naive way of doing this
would end up using our own getopt.h and the installed
getopt_long(), which is asking for trouble!
(obstack_init): A similar argument applies to obstack.h and
obstack_init().
* m4/ltdl.c: Upgraded to latest bleeding edge version again.
On Solaris-2.5 (at least) the native dlopen implementation
gets confused about m4.o when looking for module "m4". This
version always looks for .la an .$lib_ext suffixed names first
to work around the problem. Sigh.
* po/POTFILES.in: Take account of these file movements.
* src/Makefile.am (m4_SOURCES): removed eval.c.
(EXTRA_m4_SOURCES): removed numb.c and numb.h.
* m4/Makefile.am (libm4_la_SOURCES): added eval.c.
(EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
* modules/m4.c (builtin_eval): Use m4_evaluate().
* m4/eval.c: Moved here from src/eval.c to facilitate
implementation of eval() builtin as part of the `m4' loadable
module.
(m4_evaluate): renamed from evaluate for namespace cleanliness.
* m4/numb.c: Moved here from src/numb.c, since it is #included
into eval.c at compile time.
* m4/m4module.h (m4_evaluate): Added prototype.
* src/m4.h (evaluate): Removed prototype.
2000-11-25 Gary V. Vaughan <gary@gnu.org>
* modules/perl.c (builtin_perleval): Use PL_na for
compatibility with perl-5.6.
* src/main.c (main): It is now safe to
``m4_module_install("m4")'', without tripping over the m4
binary itself!
* m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
versions having fixed the insidious module search order bug.
* m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
* configure.in: Figure out whether to use the installed
getopt.h or the supplied one.
* src/Makefile.am: ditto.
* po/POTFILES.in: List files in their new positions.
* config/ltmain.sh: This needs to be checked in to match the
libtool macros copied to acinclude.m4 (until a released
libtool copes with m4's needs).
* bootstrap: Run gettextize.

* Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
src dir and immediately after libm4 is built for confidence that
it doesn't rely on the src directory.
(SUBDIRS): Moved doc dir to the end since helptoman.pl and
makeinfo stop the build on cygwin (because they don't work).
* src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
* m4/m4private.h: ...is not a public header, so moved to src.
Add `#include <config.h>', `#define _COMPILING_M4' and

From Akim Demaille <akim@epita.fr>

* src/ltdl.c: Use access() to abort doomed module load attempts
if module file does not exist.
* src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
getopt1.o will already be used if appropriate, so I moved getopt.c
and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
* modules/modpath1.test: Use correct filename in header line.
* modules/modpath2.test: ditto.
* modules/modpath3.test: ditto.
* modules/modpath4.test: ditto.
Without these changes lt_dlopen("test") attempts to
LoadLibrary("/bin/test") on Windows, which although harmless
generates a spurious error message which spoils most of the tests:
* modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
(TESTS): s/test.test /modtest.test /
(pkglibexec_LTLIBRARIES): s/test.la /modtest.la /

* lib/COPYING.LIB: updated to version 2.1.
* lib/m4module.h: restructure the M4_SCOPE code to work when
creating a dll which links with libm4.la and both DLL_EXPORT
(for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
both defined.
2000-01-11 Gary V. Vaughan <gary@gnu.org>
Merged the following changes from my tree:
1999-06-15 Gary V. Vaughan <gary@gnu.org>
* configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
ported to compile shared libs.
* configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
use `__declspec(dllimport)' when linking libm4.la on win32.
* src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
* configure.in (M4OBJS): Discover whether we need the shipped
implementation of getopt_long.
* src/Makefile.am (m4_LDADD): Link the getopt objects into the
main binary here, as opposed to the module library in lib/libm4.la.
1999-06-14 Gary V. Vaughan <gary@gnu.org>
* modules/README: Updated to describe the improved libltdl based
module scheme.
* README (cygwin): Added some compilation notes for building m4
correctly under cygwin.
* TODO: Cleaned out the entries for the module system since they
are now implemented.
* *.[ch]: __P is in the compiler's reserved namespace, so replaced
all instances of __P with M4_PARAMS.
* lib/getdate.h: removed unreferenced file.
* lib/m4private.h: New file to define the private interface to the
token_data struct, which must be shared between m4module.c, and
builtin.c but not exported to modules built from the installed
m4module.h since it's size changes depending on compile time
options.
* src/m4.h: Lots of stuff moved to lib/m4module.h.
* lib/m4module.h: New file to define the interface available when
compiling m4 modules.
* lib/m4module.c: Moved parts of builtin.c, and m4.c which are
necessary for module compilation into this new file.
* lib/Makefile.am (include_HEADERS): install headers (renamed to
avoid nameclash with other system headers) necessary for compiling
modules.
(libm4_la_SOURCES): always include error.c, obstack.c and regex.c
so that modules can include the (renamed) installed headers and
be guaranteed a matching implementation.
* lib/m4error.h: renamed from error.h.
* lib/m4obstack.h: renamed from obstack.h.
* lib/m4regex.h: renamed from regex.h.
* configure.in (AC_REPLACE_FUNCS): Don't look for a system
implementation, simply include the shipped version
unconditionally, otherwise it is hard for a module to know
whether the m4obstack.h header it is using matches the
implementation it ends up linking against.
(jm_WITH_REGEX): Include regex into libm4 unconditionally for
the same reason.
1999-05-18 Gary V. Vaughan <gary@gnu.org>
* examples/misc.test: Don't run this test on machines which don't
have a root user in /etc/passwd (e.g. cygwin).
* tests/get-them (/^@example$/): Error messages might have a
``.exe'' suffix to the program name, or else use the libtool
``.libs/lt-m4'' binary, or generally have an unexpected path. All
of these cases are now catered for when comparing error messages
in generated tests.
* tests/other-tests/*.test: ditto.
* examples/*.test: ditto.
* tests/defs (M4): use libtool execute mode.
* examples/defs (M4): ditto.
* tests/get-them (END): explicitly close any open file.
(printthem): In a regular expression, '{' is the start of a repeat
count! Use `[{]' for a literal open brace.
(/^@node /): Don't use substr on a string shorter than the trim
length.
1999-05-17 Gary V. Vaughan <gary@gnu.org>

automake warnings about missing lib prefix.
(time_la_LDFLAGS): ditto
(stdlib_la_LDFLAGS): ditto
1999-11-10 Paul Eggert <eggert@twinsun.com>
* src/m4.h: Include error.h, since our macros use error.
* src/m4.c: Don't need to include error.h.
1999-11-09 Paul Eggert <eggert@twinsun.com>
* src/m4.h (voidstar): Define to void * if __STDC__ is defined
and zero, as Solaris 7 cc does.
(bcopy): Remove macro; no longer needed with new obstack.h.
* src/output.c (freeze_diversions): Don't assume that a
diversion size can fit in `int'. Check for diversion file

* src/m4.c (--load-module): dynamically load named runtime module
into running executable before reading the source.
(--module-directory): prepend a directory to the module search
path.

1999-03-26 Gary V. Vaughan <gary@gnu.org>
* src/module.c: removed. No longer required.

* acinclude.m4: removed. `aclocal -I acm4' handles this much
better.
* acm4/Makefile.am (ACINCLUDE_M4): ditto.
* acm4/gettext.m4: removed. It causes a multiple definition vs.
the installed gettext.m4 file when running aclocal.

* configure.in (AM_INIT_AUTOMAKE): bumped version number to
distinguish this from the last prerelease.

configure time options.
1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
* src/module.c (module_try_load): Don't try to be clever and
overwrite argument string. Instead allocate all constructed
strings locally, since they can have arbitrary lengths. Make
arguments pointers to const.
(module_search): Simplify due to above change.

and mpeval.
1998-11-28 René Seindal <rene@seindal.dk>
* src/m4.c (main): New option --import-environment (no single
letter option).
* When configured with --with-gmp both the normal (fast) eval()
and the gmp aware mpeval() are defined. To restore previous
bahaviour use "define(`eval', defn(`mpeval'))".
* tests/other-tests/gmp.m4: Changed to use mpeval().
* src/evalmp.c: New file for compiling eval.c as gmp aware.
Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
* src/eval.c: Now includes "numb.c" directly. Everything in this
file must by static, except evaluate(), which is changed to
mp_evaluate() if USE_GMP in force.
* src/numb.c: Changed to be included by eval.c instead of being
compiled separately. Everything is declared static.
* src/numb.h: Removed declarations of functions, as numb.c is now

for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
1998-11-27 René Seindal <rene@seindal.dk>
* Error messages now always print program name before input file
name as specified by GNU coding standards. Reported by Akim
Demaille <demaille@inf.enst.fr>.

format.
(Eval): Do.
* tests/get-them: Minor change to sed script due to changed error
message format.
* src/m4.c (print_program_name): New func used to print program
name, input file and line number in error (). Used as an
error_print_progname handler.
(reference_error): Removed.

generic search path handling.
* src/path.c: Removed all module specific code and introduced new
functions of more generic search path handling.
1998-11-24 René Seindal <rene@seindal.dk>
* configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
included gettext, as <libintl.h> might not be found
otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
1998-11-22 René Seindal <rene@seindal.dk>
* src/output.c (insert_diversion): Fixed bug that might cause m4
to read from standard output! Triggered by input
'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
so now 'undivert(0)' does nothing.
1998-11-18 René Seindal <rene@seindal.dk>
* Prerelease 1.4m.
* src/input.c (set_word_regexp): Fixed a bug, where word_regexp
could be changed when compiling a illegal regexp, causing later
use of the regexp to dump core.
* src/module.c (module_load): Changed error message to conform to
standards.
* src/m4.c (usage): Added message about reporting bugs.

and AM_PROG_LIBTOOL.
* acm4/modules.m4 (AM_WITH_MODULES): Redone completely to work
with libtool.

libtool. The modules are compiled as shared libraries, and are
renamed when installed.
* src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
USE_SHL_LOAD to HAVE_SHL_LOAD
* src/builtin.c (shipout_string): Now tests for a NULL string.
* src/module.c: New level of indirection around non-portable
functions to load shared objects. Intended to encapsulate the non
portable parts better and to reduce the number of #ifdefs in the
code.
* Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
directory modules/ to the distribution.
1998-11-15 René Seindal <rene@seindal.dk>
* Prerelease 1.4l.
* modules/stdlib.c: New module `stdlib' defining some standard

getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
* src/builtin.c (shipout_string): New convenience function for
builtins and modules.
* src/module.c (module_load): Tentative support for
shl_load/shl_findsym, but I cannot test it. Copied from MetaHTML.

by Brian J. Fox <bfox@datawave.net>. This change allow modules to
build and install automatically, and it is prepared for other
interfacec than dlopen().
* src/builtin.c (predefined_tab): Added __m4_version__ for the
current version of GNU m4. It is a GNU extension.
1998-11-14 René Seindal <rene@seindal.dk>

* Prerelease 1.4k.
* tests/Makefile.am (GENERATED_TESTS): Renamed gentest to
generated-tests.
* tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
maintained tests in tests/other-tests. These currently tests for
8-bit transparency, multiple precision arithmetic and sync-line
output. Test for stackoverflow detection does not work.

* examples/mktests.sh: New file. Help program for creating test
files.
* tests/mkconfig.sh: New file to generate tests/config.m4 and
tests/config.sh. This is for tests of configure selectable
features. Picks up all set WITH_ and ENABLE_ veriables from
config.h
* src/path.c (path_search): Added argument 'char **expanded_name'
to return the expanded name.
* src/m4.h: Added 2nd argument to declaration of path_search().

1998-10-07 René Seindal <rene@seindal.dk>
* Prerelease 1.4j.

.test, as the files are no longer just m4 input.
* tests/get-them (FILE): Changed .m4 extension to .test.
* src/m4.h (token_type): New token type TOKEN_SPACE introduced.
Otherwise quoted strings with leading whitespace first in a macro
argument would be eliminated.

(expand_argument): Do.
* src/input.c (next_token): SPACE and NUM/OTHER characters are only
grouped together iff both quote and comment strings are single
character. Otherwise they might include a comment/quote leader.
(next_token): Returns new token type TOKEN_SPACE.
* src/builtin.c (push_builtin_table): New function to push a
builtin_table on the stack without installing its contents.
(find_builtin_by_name): Added call to push_builtin_table() if
reading frozen files. Otherwise the builtins named in the frozen

that are of use for other modules (shipout_int, numeric_arg,
skip_space, bad_argc), and the macros ARG() and DECLARE().
* src/builtin.c (install_builtin_table): New function. Each
module brings in a builtin_table, which is pushed on a stack.
(struct builtin_table): New struct for list of builtin_tables.
(m4_loadmodule): New function to implement builtin "loadmodule".
(shipout_int): No longer static, to be used by modules.
(numeric_arg): do.
(skip_space): do.
(bad_argc): do.
(builtin_init): changed to call install_builtin_table()
(find_builtin_by_name): Now searches all builtin_tables
(find_builtin_by_addr): do.
* src/path.c: Reorganised to allow for two search paths, one for
include files and one for modules.
* src/m4.h: Added declarations for new functions in module.c and
in path.c.
* src/m4.c (main): Added call to module_init().
* modules: New directory with a few demo modules.
* Makefile.am (EXTRA_DIST): Added modules/* since modules/ is not
in SUBDIRS.
* configure.in: Added modules/Makefile to AC_OUTPUT.
* configure.in: Added code to implement --with-modules. Tests for
<dlfcn.h> and -ldl.
* acconfig.h: Added WITH_MODULES
1998-10-02 René Seindal <rene@seindal.dk>
* examples/Makefile.am (pkgdata_DATA): Removed special target for
check and variables TESTS. These tests are now run from the
tests/ directory.
* tests/Makefile.am (OTHER_TESTS): Added tests from the example/
directory. The files stay there but the tests are run from the
tests/ directory.
* tests/Makefile.am (EXTRA_DIST): Added run-test.
* tests/run-test: New file. Run a test manually
* tests/Makefile.am, tests/get_them: Moved automatically generated
tests (from the manual) to sub directory tests/gentest/. The
tests/ directory had gotten a bit messy.
1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
* examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
wrap}.test: Added a few testcases.
1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
* Prerelease 1.4h.
* lib/Makefile.am (noinst_HEADERS): regex.h added
* configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
* acm4/Makefile.am: created providing rules to create
$(top_srcdir)/acinclude.m4 to be used by aclocal.
* tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
`C'. Reported by Ulrich Drepper.
* Makefile.am (SUBDIRS): Removed checks directory
* configure.in (AC_OUTPUT): Removed checks/Makefile
* doc/m4.texinfo (Patsubst,example): @comment added to preserve
the space when m4.texinfo is edited and whitespace.el is active.
(Defn,example): idem.
1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
* doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
../COPYING. ../Makefile is a file which is certainly present when
test is executed in testSubDir. One can't be sure that the COPYING
file is in .. or ../.. in all situations, the ../Makefile is
always there.
* doc/m4.texinfo (Include): adjusted expected test output
according to new tests, i.e. the input will always come from the
file `in' created by the test.
* tests/Makefile.am: Added three lines at the top to get
esyscmd.1.test working.
* tests/get-them: modified to generate clearer tests who will need
less maintenance when new test examples are created in
`doc/m4.texinfo'. All tests are small (nearly stand-alone, they
need the generic file `defs') shell scripts creating `in', `ok',
`out' and when apropriate `okerr' and `err' in the directory
`testSubDir' when executed. The compare of `ok' and `out'
(and of `okerr' and `err') will be the exit status of the test.
`out' must match `ok' (and `okerr' must match `err') for the test
to be succesful.
* tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
the tests generated by tests/get-them getting it input normally
from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
(dot) before the numeric part) is reserved for all other (hand
written) tests. The `+' means one or more times.
1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
* doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
supported short man page to refer to info documentation

ftp://ftp.iro.umontreal.ca/pub/contrib/pinard/maintenance/libit.
* configure.in (AC_REPLACE_FUNCS): added xmalloc xstrdup
* lib/Makefile.am (libm4_a_SOURCES): removed automakely supported

lib/rx.{c,h}: added
* configure.in (AC_CHECK_FUNC): getopt_long
* src/m4.c (usage): Report bugs to m4-bugs@gnu.org.
* TODO: added entry about dependencies
1998-08-10 René Seindal <rene@seindal.dk>

table. All categories are assigned a syntax code and tokens are
read according to this table.
1998-08-09 René Seindal <rene@seindal.dk>
* src/numb.{c,h}: New files, implements multiple precision eval
using GNU gmp. Originally submitted by John Gerard Makecki
(johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
* doc/m4.texinfo (Eval): Added documentation for multiple
precision arithmetic library support.
* src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes

1994-10-30 François Pinard <pinard@iro.umontreal.ca>
* src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
__STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler

implicit rules, now that regularity makes this possible.
Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
of ansi2knr whenever it is needed.
* configure.in: Adjusted for correct STACKOVF substitution.
* src/debug.c (trace_format): When not __STDC__, use (...) as a
parameter list, so ansi2knr will convert it to (va_alist) va_dcl.

configure does it automatically.
Reported by Jim Meyering.
1994-09-23 François Pinard <pinard@iro.umontreal.ca>

which is repeated in both goals.
1994-09-13 François Pinard <pinard@iro.umontreal.ca>
* Release 1.3.
* Makefile.in: Group all *clean-recursive goals in one, using sed
to remove `-recursive' while calling make recursively. Also, use
a subshell for each recursive $(MAKE).
Reported by Jim Meyering.
* src/m4.h (memcpy): Define with bcopy for BSD systems.
Reported by Kaveh R. Ghazi.
* src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
4.1.3 requires -ldl to link even ansik2nr, and we need a way to
specify it.
* configure.in: Use date instead of touch for stamp-h.
* Makefile.in (stamp-h.in): Idem.
* Makefile.in (distclean, realclean): Force serial execution of
both goals, in case parallel makes are being used.
Reported by Jim Meyering.
* src/Makefile.in (DISTFILES): Distribute TAGS.
(distclean): Do not remove TAGS.
(realclean): Remove it.
Reported by Karl Berry.
1994-09-10 François Pinard <pinard@iro.umontreal.ca>

* configure.in: Correct stack overflow detection logic, taking
care of systems having only incomplete implementations (like for
Pyramid 9820 OSx 5.0d).
Reported by Kaveh R. Ghazi.

frozen. Do not call builtin_init when reloading frozen state.
Speed up diversion processing:
* output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,

structures.
(insert_file): Use better buffering.
Reported by David MacKenzie.

dist works from another build directory.
1994-08-27 François Pinard <pinard@iro.umontreal.ca>

description for debugging flags.
1994-07-29 François Pinard <pinard@iro.umontreal.ca>
* configure.in: If sigaction is available and SA_ONSTACK defined,
use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
defined, use sigvec. Else don't compile stackovf.c.
* stackovf.c (setup_stackovf_trap): Idem.
Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
and Simon Leinen.
1994-07-21 François Pinard <pinard@iro.umontreal.ca>

Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
* Makefile.in (install): Have install depend on all too, for lib
to be remade as needed.

providing ulimit, instead of using only ksh.
Reported by Jim Avera and Joseph E. Sacco.
1994-07-12 François Pinard <pinard@iro.umontreal.ca>
* Makefile.in (check): Have it depend on all instead of m4. In
this way, a change in lib will be detected and processed.
* builtin.c (numeric_arg): Use strtol and verify the conversion,
instead of using sscanf which stops as soon as there is a
non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
and divert(1xyzzy) were all accepted without any warning or error
messages.

handlers), and a default error message if the fault address is not
available (when neither siginfo.h nor BSD sigcontext are supported).
* configure.in: Changes for stackovf.h: Check for sigcontext,
sigaction, sigstack, and define rlim_t as int if necessary.
* acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
* examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
* ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.

Reported by Ian Taylor.
1994-07-02 François Pinard <pinard@iro.umontreal.ca>
* configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
because siginfo.h is unrelated to standard headers, and siginfo.h
is already checked for.
Reported by Joseph E. Sacco.
* acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
PROTOTYPES.
* aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
AC_PROTOTYPES.
1994-06-29 François Pinard <pinard@iro.umontreal.ca>
* builtin.c (substitute): Use \& to represent this part of the
string which was matched by the whole regexp, instead of
representing the whole string. Any usage of \0 issues a warning
and acts like \&, it will disappear in some subsequent release.
1994-06-27 François Pinard <pinard@iro.umontreal.ca>
* m4.c: Complete prototype for forwarded declaration of usage.
* input.c (init_macro_token): Correct own reference in error
message. Previous name get_macro_func was referred to instead.
(next_char): Correct own reference in error message. Previous
name advance_input was referred to instead.
* m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
* eval.c (logical_or_term, logical_and_term, or_term, xor_term,
and_term, not_term, logical_not_term, cmp_term, shift_term,
add_term, mult_term, exp_term, unary_term, simple_term): Add
prototype to forwarded declarations. Declare parameter v1 as
eval_t * instead of int *. Same for local variable v2 in dyadic
functions. Same for result in exp_term.
* builtin.c (m4_eval): Declare value as eval_t instead of int.
(ntoa): Declare value as eval_t instead of int. Declare uvalue as
unsigned_eval_t instead of unsigned int. Change casts accordingly.
(shipout_int): Cast first argument of ntoa to eval_t.
Reported by Thorsten Ohl.
* macro.c: Complete the prototypes of forwarded expand_macro and
expand_token.
Reported by Thorsten Ohl.

Reported by Tom McConnell.
* ansi2knr.1: New, from elsewhere.
* Makefile.in (DISTFILES): Distribute ansi2knr.1
* Makefile.in (stamp-h.in): Avoid running ./config.status if
stamp-h does not exist yet. This avoids running it a second time
just after the initial ./configure.
Reported by David MacKenzie and Tom McConnell.
* m4.h: Replace the enum debug_info declaration with a series of
#define's. The Ultrix 3.1 compiler would otherwise need casting
(int) to most references, when used in expressions.
Reported by Tom McConnell.
1994-06-25 François Pinard <pinard@iro.umontreal.ca>
* aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
calls the compiler. Previously, FP_PROTOTYPES was only calling
the preprocessor; by not being subject to CFLAGS, this was
discouraging those flags asking for ANSI compilation.
* acconfig.h: Document HAVE_PROTOTYPES.
* configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
* m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.

* configure.in: m4_undefine changeword before using AC_ENABLE.
* m4.h: Declare prototypes for error (for ANSI compilers only),
prefix_all_builtins and reference_error.
Reported by Tom McConnell.
* input.c (set_word_regexp): Do not try to initialize the array
test from a string, this does not work with non-ANSI compilers.
Reported by Eric Backus.
* Makefile.in (dist): Clean examples/ before saving it.
(distclean-local): Also remove stamp-h.
Reported by Eric Backus.
* Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
non ANSI compilers.
Reported by Tom McConnell.

name.
Reported by Krste Asanovic and Pete Chown.
[These modifs all depend upon ENABLE_CHANGEWORD]

Things like `eval(08)' used to return 0 with no diagnostic.
* m4.h: Capitalize first letter of all macro arguments in
definitions.
* m4.c: Declare warning_status, initialize it to 0. Add new
option -E, or --fatal-warnings, which sets warning_status to
EXIT_FAILURE instead.

that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
also tested it on a Sun Sparc workstation running SunOS 4.x.
* format.c (format): When not HAVE_EFGCVT, m4 was failing the
49.format check, abusing a `union values' argument with sprintf
without selecting the proper field. Now, save the formatting type
first, delaying the fetch of the corresponding argument.
Reported by Joseph E. Sacco and Tom Quinn.
* format.c (format): Remove const from char *fmt declaration when
not HAVE_EFGCVT, because a NUL may be forced into it.
* m4.h: Declare atof() when not STDC_HEADERS.
Reported by Joseph E. Sacco.

1993-11-27 François Pinard <pinard@iro.umontreal.ca>
* m4.h: Delete extern sys_nerr, sys_errlist declarations, and
syserr() macro. Delete errref, add reference_error and M4ERROR.
* m4.c: Replace errref, which was returning an input reference
string, with reference_error, which prints it on standard error.
* builtin.c, output.c: Use errno as second parameter to error,
instead of using syserr() with %s.
* *.c: Use M4ERROR instead of error: no more errref() with %s.
Doing so, the program name appears after the input reference
instead of before, which eases M-x next-error processing.
1993-11-24 François Pinard <pinard@iro.umontreal.ca>
* checks/get-them: Escape braces with backslashes in patterns,
because HPUX-9.01 awk needs this.

* m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
macros, replace error_message_prefix() declaration by errref()'s.
Declare xrealloc, for use in errref().
* m4.c: Delete error_message_prefix() function, add errref().
* *.c: Use error() systematically in place of all error macros,
now that error() flushes stdout first. Make needed adjustments.
* m4.h: Remove const in sys_errlist[] declaration, it creates
conflicts on SGI and Alpha.
Reported by Kaveh R. Ghazi.
1993-11-20 François Pinard <pinard@iro.umontreal.ca>

* builtin.c (m4_eval): Cast strlen to (int) before comparing.
* input.c (input_init): Initialize quote and comment strings
explicitely instead of calling set_quotes and set_comment: by
doing so, we ensure we do not free uninitialized variables.
* checks/check-them: Reverse arguments to both diff, so the
expected is on the left and the obtained on the right.
* m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

Delete debug_print and debug_message routines, add
debug_message_prefix routine.
* builtin.c, debug.c: Replace debug_print routine calls with
DEBUG_PRINT* macro calls.

* debug.c: Include <stdarg.h> or <varargs.h>.
(trace_format): Use stdarg instead of varargs if __STDC__.

Reported by Kaveh R. Ghazi.
* macro.c (call_macro): Add * in (*SYMBOL_FUNC (sym)) (...).
Reported by Karl Vogel.
1993-11-09 François Pinard <pinard@iro.umontreal.ca>

Reported by Bernhard Daeubler, Eric Backus, Hal Peterson, Hoang
Uong, Ian Taylor, Kaveh R. Ghazi, Tom McConnell and Walter Wong.
1993-11-08 François Pinard <pinard@iro.umontreal.ca>

* Release 1.0.3
This is still a beta release for the future GNU m4 version 1.1.
* lib/alloca.c: New, from elsewhere.
* lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
* m4.h: Do not define index/rindex if already defined. If
FALSE/TRUE are already defined, do not redefine them, but merely
define boolean typedef to int.
* Makefile.in: Use $(DEFS) while compiling ansi2knr.
* ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
because some C compilers do not like connectives with #ifdef.
* m4.h: Define `volatile' only if __GNUC__, instead of once for
__GNUC__ and once for __STDC__.
* lib/regex.h: Leave const alone, AC_CONST will take care of it.
* checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
Makefile dependencies. Without it, make keeps destroying and
remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
* m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
to diversion/DIVERSION, this was a spelling error.
* m4.c: Declare version[], remove #include "version.h".
* version.h: Deleted.
* Makefile.in: Remove references to version.h.
* output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
production, by using a simpler and more robust algorithm. This
solves the problem of synclines sometimes written in the middle of
an output line. Delete sync_line() and output_lines variable.
* m4.h: Remove sync_line prototype and output_lines declaration.
* input.c (next_char), output.c (shipout_text): Remove references
to output_lines.
* input.c (push_file, pop_file): Merely put the value -1 in
output_current_line instead of calling sync_line, for delaying a
single `#line NUM FILE' before next output line. Do not test
for sync_output, because this is unnecessary clutter.
* output.c (make_divertion, insert_divertion): Idem.
* input.c: Rename must_advance_line to start_of_input_line, for
consistency.
* debug.c (trace_header): Select a new debug line format, which
better complies with GNU standards for formatting error messages.
With option `-dfl', M-x next-error might be used on the output.
* m4.c (vmesg): Adjust format of error output to GNU standards.
* m4.texinfo: Adjust examples for `make check' to work.
* m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
case for enum debug_info constants, which were all lower case.
* builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
re_search_2.
* lib/regex.[ch]: Use new version from textutils 1.3.6, with some
collected patches. I tried a few times using newer regex.[ch], it
mysteriously stopped aborting with this one. Insecure feeling...
* lib/Makefile.in: Distribute regex.[ch].old, just in case!
1992-12-18 François Pinard <pinard@iro.umontreal.ca>
* m4.c: Change `--no-warnings' to `--silent'.
Reported by David MacKenzie.
* m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
leave it off for now. See comment in m4.c for justification.
Reported by David MacKenzie.
* configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
* m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
* Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
* Makefile.in: Ensure recursive cleaning is done before local
cleaning for all clean goals.
* builtin.c (ntoa): Ensure the value is always interpreted as a
signed quantity, whatever the radix is.
1992-11-18 Jim Meyering <meyering@idefix>
* builtin.c, format.c, input.c: Split long lines.
* m4.c: Use typedef macro_definition instead of struct
macro_definition.

1992-11-17 François Pinard <pinard@iro.umontreal.ca>
* *.[ch]: Remove all trailing whitespace, in code and comments.
* configure.in: Find some awk.
* Makefile.in: Add $(AWK) to MDEFINES.

* checks/get_them: Use $AWK instead of gawk. Add a close in the
awk script when switching files, because without this, mawk runs
out of file descriptors.
1992-11-16 François Pinard <pinard@iro.umontreal.ca>
* Makefile.in (realclean): Delete m4.info*.
Reported by Jim Meyering.
* Makefile.in: Adjust and link with checks/Makefile.

recognizable by next-error, also use a better message.
1992-11-16 Jim Meyering <meyering@idefix>
* m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
And use that only if __GNUC__ since we're using it's GCC-specific
semantics that tell the compiler the associated function doesn't
return.
* builtin.c (substitute): Don't use character as an array index.
(dumpdef_cmp): Make formal arguments `const void *' to avoid
warnings with gcc -W -Wall on systems with qsort prototype.
(m4_errprint): Cast obstack_finish to `char *' to avoid warnings
from gcc -W -Wall.
* eval.c (most functions): Add parentheses to assignments used
as truth values go avoid warnings from gcc -Wall.
* input.c, m4.c, output.c, path.c, symtab.c: Declare static
any functions that don't need external scope.
* builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
(many functions and arrays): Declare `const'.
1992-11-15 François Pinard <pinard@iro.umontreal.ca>
* *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
removing the declaration from m4.h. Also rename false to FALSE
and true to TRUE.
* lib/Makefile.in (Makefile): New goal.
* Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
so heavily loaded. It gets more easily overridable, calling make.
Reported by Jim Meyering.
* Makefile.in (dist): Get .fname from the current directory name,
instead of from version.h. I need updating many files manually,
when the version changes, version.h is just one of them.
1992-11-14 François Pinard <pinard@iro.umontreal.ca>
* m4.h: Remove the tag `boolean' on the enum introducing typedef
`boolean'. This tag conflicts with <sys/types.h> on SVR4.
Reported by Tom McConnell.
1992-11-13 François Pinard <pinard@iro.umontreal.ca>
* m4.texinfo: Correct the examples for 33.divert, 38.divnum,
39.cleardiv, which were describing missing or spurious newlines.
Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
do not depend on machine word size, `/bin/false' implementation,
or `wc' output format. `make check' is more dependable, now.
* checks/check_them: Summarize the failed tests by listing their
name, at end. If none, issue `All checks successful'. Output
`Checking' instead of `Input file:'.
* checks/get_them, checks/check_them: Reindented.
* Makefile.in (dist): chmod a+r before making the tar file.
1992-11-12 François Pinard <pinard@iro.umontreal.ca>
* builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
* input.c (next_token): Reinitialize token_buttom just after using
it as a watermark with obstack_free. Or else, a future token, big
enough for triggering reallocation of the obstack chunk, could
void the initialized value of token_buttom, later causing panic in
obstack_free. Rename token_buttom to token_bottom everywhere.
* m4.h: Before declaring errno, first include <errno.h> and
ensure that it does not define errno.
Reported by Richard Stallman.
1992-11-11 François Pinard <pinard@iro.umontreal.ca>
* builtin.c: Define and use DECLARE macro for builtins.
* builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
argument, this is a common idiom for introducing long comments.
* builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
arguments. The last argument was silently ignored.
* m4.c (cmd_error): Add a missing semicolon before va_end().
1992-11-10 François Pinard <pinard@iro.umontreal.ca>
* Makefile.in: Now handle protoized sources. Define and use U.
Compile and use ansi2knr with old compilers. Update DISTFILES.
Add `aclocal.m4' to `configure' dependencies.
* ansi2knr.c: New, from Ghostscript distribution.
* configure.in: Define U through FP_PROTOTYPES for old compilers.
Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
* aclocal.m4: New, provide FP_PROTOTYPES.
* m4.h: Conditionnaly protoized through Args, save for varags.
* builtin.c: Protoized. Then:
Include <sys/types.h> if size_t is not defined, before "regex.h".
(m4_ifelse): Fetch built-in name properly for diagnostic.
(m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
(m4_regexp): Add const to `msg' declaration.
(m4_patsubst): Add const to `msg' declaration.
* debug.c: Protoized, save for varargs.
* eval.c: Protoized.
* format.c: Protoized.
* input.c: Protoized.
* m4.c: Protoized, save for varargs. Then:
(xfree): Accept void * instead of char *.
(xmalloc): Return void * instead of char *.
(xrealloc): Accept and return void * instead of char *.
* macro.c: Protoized.
* output.c: Protoized.
* path.c: Protoized. Then cast some (char *) over xmalloc's.
* symtab.c: Protoized.
1992-11-06 François Pinard <pinard@iro.umontreal.ca>
* m4.texinfo: Remove directory from diagnostics in 30.include,
51.eval, 56.errprint and 57.m4exit tests.
* m4.h: Remove declarations for int or void system functions, they
cause more conflicting trouble than they make good.
* configure.in: Avoid configuration header file. Add some tests.
* m4.h: Remove #include "config.h".
* Makefile.in, lib/Makefile.in: Implement Autoconf interface.
Then, rewritten for better compliance with GNU standards.
1992-11-05 François Pinard <pinard@iro.umontreal.ca>
* format.c (format): Avoid syntax error if not HAVE_EFGCVT,
because of a misplaced #endif.
* Many *.[hc] files: Correct intra-line spacing here and there,
according to GNU indent 1.6 advice.
* configure.in: New, using Autoconf 1.2.
* m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
* Delete old configure.in, configure, etc/configure.in,
etc/configure, lib/configure.in, lib/configure and config/*.
Reported by Jason Merrill.
* symtab.c (hash): Change (char) NULL to '\0'.
Reported by Jason Merrill.
* Delete .vers, etc/newdist.sh, etc/newvers.sh and
etc/nextvers.sh. Release numbers will be edited `by hand'.
* version.h: De-automatize, force value in.
* m4.c: Changes in order to use a newer getopt.h.
Reported by David MacKenzie.
* checks/: New name for examples/.
* checks/get_them: New location for etc/get_examples.
* checks/check_them: New location for etc/check_examples.
* Makefile.in, checks/get_them, checks/check_them: Adjust.
* lib/vfprintf.c: New location for etc/vfprintf.c.
* Delete empty etc/.
* examples/: New name for test/.
1992-03-10 François Pinard <pinard@iro.umontreal.ca>
* Makefile.in (check): Add m4 as dependency.
* m4.c: Accept --no-warnings instead of --no_warnings, and
--no-gnu-extensions instead of --no_gnu_extensions. Make the
usage message more informative.
Reported by David MacKenzie.

* etc/check_examples: New name for check_examples.sh.
* etc/get_examples: New name for get_examples.sh.
* Makefile.in, etc/Makefile.in: Use new names.
* Makefile.in: Transmit $(CC) while making in lib.
* Many *.[hc] files: GNU indent'ed, with further fine tuning of
code disposition by hand.
1992-03-08 François Pinard <pinard@iro.umontreal.ca>
* m4.h: Delete definitions for abort() and exit().
Reported by Richard Stallman.
* config/hmake-unicos, config/s-unicos.h: New files.
Reported by Hal Peterson.

1991-10-24 René Seindal <seindal@diku.dk>
* Release 1.0. Many thanks to those, who provided me with bug
reports and feedback.
* Uses GNU configure, taken from the gdb distribution.

* The -Q/+quiet option is added, which suppresses warnings about
missing or superflous arguments to built-in macros.
* Added default options via the M4OPTS environment variable.
* The built-in format can now be configured to use sprintf as
the formatting engine, for systems without [efg]cvt(3).

François Pinard and Roland H. Pesch for providing me with reports.
* The builtins incr and decr are now implemented without use of
eval.
* The builtin indir is added, to allow for indirect macro calls
(allows use of "illegal" macro names).
* The debugging and tracing facilities has been enhanced
considerably. See the manual for details.
* The -tMACRO option is added, marks MACRO for tracing as soon
as it is defined.
* Builtins are traced after renaming iff they were before.
* Named files can now be undiverted.
