Doing so prevents bootstrapping with bleeding-edge autotools,
because of harmless deprecation warnings (that are not planned
to become hard errors for at least a few years to come). And
unfortunately, options in AM_INIT_AUTOMAKE take precedence over
those given on the command line (this is a long-time wart of
automake).
* configure.ac (AM_INIT_AUTOMAKE): Drop '-Werror' option.
Copyright-paperwork-exempt: yes

* bootstrap: Update from gnulib.
* bootstrap.conf (gnulib_tool_option_extras): Define.
* lib/Makefile.am: Initialize numerous automake variables so that
generated code in gnulib.mk may use += to append to them.
* configure.ac: Add AM_PROG_AR, to placate newer automake.
Mark functions as pure of const, per recommendations enabled by
new gcc -W options. Apply _GL_ATTRIBUTE_PURE and _GL_ATTRIBUTE_CONST.
* src/common.h: Apply new function attributes.
* src/pch.c: Likewise.
* src/pch.h: Likewise.
* src/util.c: Likewise.
* src/util.h: Likewise.
* configure.ac: Use -Wno-format-nonliteral.
* m4/.gitignore: Update.
* gnulib: Update to latest.
* cfg.mk: Exempt src/util.c from two tests, to avoid new
"make syntax-check" failures.
* configure.ac: Remove AC_SYS_LARGEFILE, subsumed by ...
* bootstrap.conf (gnulib_modules): ...this. Use largefile module.
* gnulib: Update to latest.
This is useful to Mac OS X 10.5 users if/when configure
is generated using autoconf prior to v2.68-80-gdb2f2e0.
* configure.ac (WERROR_CFLAGS): Don't turn off -Wmissing-declarations
and admit that it's not worth fixing the few warnings triggered
by -Wmissing-format-attribute.
* src/patch.c (main): Set all file attributes of the temporary output
file before renaming it over the final output file (possibly replacing
the input file). Pass the input file name to set_file_attributes().
* src/util.c (set_file_attributes): When enabled (USE_XATTR), also
copy extended attributes including attributes which define
permissions.
(copy_attr_error, copy_attr_quote, copy_attr_free, copy_attr_check,
copy_attr): Helper functions for copying extended attributes.
* m4/xattr.m4 (gl_FUNC_XATTR): Import from coreutils.
* src/Makefile.am (patch_LDADD): Add $(LIB_XATTR) here.
* bootstrap.conf: Use the gnulib verror module.
* bootstrap.conf: Use the gnulib fcntl-h and sys_stat modules.
* src/common.h: Remove the declarations provided by gnulib sys_stat.
Always include fcntl.h (and depend on gnulib fcntl-h).
* src/util.h: Remove duplicate include of <timespec.h>.
* configure.ac: Remove obsolete checks for fcntl.h and utime.h.
* configure.ac: Add automake and gnulib macros, replace several
obsolete macros.
* Makefile.am, lib/Makefile.am, src/Makefile.am, tests/Makefile.am:
Add for automake.
* autogen.sh, INSTALL, Makefile.in, mkinstalldirs, update-version.sh:
Obsolete; remove.
* README-hacking: Import from diffutils, replace cvs with git.
* build-aux: Move gnulib auxiliary files here from the top-level
directory.
* gnulib: Add gnulib git submodule.
* bootstrap, bootstrap.conf: Import from gnulib and adjust.
* gl/lib: Remove gnulib files from the repository; they are now
imported into lib/ from gnulib as needed.
* tests/test-lib.sh: Use $abs_top_builddir exported from
tests/Makefile.am here instead of $PWD.
* m4/utimbuf.m4: This macro has been removed from gnulib. Add it here
for now; this will be replaced by gnulib's utimens module soon.
* gl/m4/strndup.m4 (gl_HEADER_STRING_H_DEFAULTS): Don't use gnulib's
strings.h replacement for now, it is too complicated to add right now.
* gl/lib/xstrndup.c: Instead of using gl_HEADER_STRING_H_DEFAULTS,
declare strndup here on systems which don't have it.
* gl/lib/strndup.c: Instead of using gl_HEADER_STRING_H_DEFAULTS,
declare strnlen here on systems which don't have it.
* gl/lib/strnlen.c: Import from gnulib.
