(S_IXUSR, S_IXGRP, S_IXOTH): Remove.
Include <time.h> unconditionally, since we can assume C89 now.
Likewise for <stdlib.h>, <string.h>.
(getenv, EXIT_SUCCESS, EXIT_FAILURE, SSIZE_MAX, strchr, strrchr,
memcmp, memcpy): Remove decl; no longer needed.
(strcasecoll, strcasecmp): Define if not built in.
(CTYPE_DOMAIN, ISPRINT, ISSPACE, TOLOWER, _tolower, errno): Remove;
we now assume C89 or better. All uses changed.
Include <stdbool.h> unconditionally now, since gnulib supports it
if the C compiler doesn't. All boolean uses of 0 and 1 now
changed to false and true.
(lin_is_printable_as_long_int): Renamed from lin_is_printable_as_long.
(main): Adjust to latest gnulib c_stack_action calling conventions.
Adjust to latest version_etc calling conventions.
Include <unlocked-io.h>, <exit.h>.
(check_child_status): Renamed from ck_editor_status, and
accept a new arg MAX_OK_STATUS. All callers changed.
Handle status 126/127 as per POSIX.
(edit): Likewise.
(main): Likewise. Fix getopt typo: -E wasn't supported.
(find_and_hash_each_line): Don't convert char *
to unsigned char *; just leave pointers as char *. This
lessens the number of potentially-dangerous casts.
(failed_locale_specific_sorting): Renamed from failed_strcoll.
All uses changed.
(compare_names): Don't invoke strcasecmp first thing when
ignore_file_name_case; if locale_specific_sorting, we should
just use that.
(main): Adjust to latest gnulib c_stack_action calling conventions.
Adjust to latest version_etc calling conventions.
Include unlocked-io.h.
(strip_trailing_cr): New var.
(STRIP_TRAILING_CR_OPTION): New enum.
(longopts, main, option_help_msgid, read_diff):
Add --strip-trailing-cr support.
(read_diff): Exit with status 126 (not 127) if errno != ENOENT
after failed execvp in child. Report this in parent.
(option_help_msgid): Mention exit status.
(main): Adjust to latest gnulib c_stack_action calling conventions.
Adjust to latest version_etc calling conventions.
Include <exit.h>.
(binary): Define to true if not declared.
(longopts): Set tabsize flag to 1.
(main): Don't output nanoseconds if platform lacks them.
Don't treat files as binary if !binary.
(set_mtime_to_now): Use 0, not NULL.
(compare_files): Mark files as nonexistent if it looks like
'patch' created inaccessible regular empty files to denote
nonexistent backups. Don't compare such files.
Clear st_* members of status of nonexistent file.
Remove now-unnecessary tests.
(specify_comparison_type): Don't report an error if the comparison
type has already been specified the same way as this one.
(usage): Mention exit status.
(main): Adjust to latest gnulib c_stack_action calling conventions.
(main): Adjust to latest version_etc calling conventions.
(EXTRA_DIST, noinst_HEADERS): Remove most entries.
(libdiffutils_a_SOURCES): Now just lib_SOURCES.
(lib_SOURCES): New macro.
(DISTCLEANFILES, MOSTLYCLEANFILES): Set to empty now.
(gnulib.mk): Include: this does most of the work eliminated
by the above changes.
manipulation" from "GNU packages".
(Translations): New node.
(Overview): Improve quality of algorithm citations.
(Binary): -q doesn't exactly cause diff to assume files are binary.
(Normal): Place after Side by Side, since it's less important.
(Detailed Context, Detailed Unified, Detailed ed,
Detailed if-then-else, diff3 Hunks, Detailed diff3 Normal):
Place at end of menu.
(Detailed Unified): Mention that fractional timestamps are
omitted on hosts that don't support them.
Mention what happens when hunks contain just one line.
(Line Group Formats, Reject Names): Fix duplicate-word typos.
(Comparing Directories): Trailing white space and empty lines are
ignored in the -X file.
(diff Options): Add --strip-trailing-cr.
(Projects): gnu -> gvc@gnu.org.
value wasn't needed. All callers changed.
(diag, diff_2_files):
Use 'true' and 'false' instead of '1' and '0', when appropriate.
(compareseq): Use lin const * local variables instead of lin *.
Don't bother checking diag's return value.
(shift_boundaries, build_reverse_script, build_script, diff_2_files):
Use char arrays, not bool arrays, since
sizeof (bool) might be greater than 1.
(paths.h): Send output to paths.ht first, and then rename to
paths.h at the end. This avoids problems if the disk is full.
It also works around what appears to be a bug with GNU make -j
(3.79.1); see <http://bugs.gentoo.org/show_bug.cgi?id=8934>.
