unnecessarily.
Don't mishandle multibyte characters in side-by-side format.
Problem reported by Erik Karlsson in
<http://lists.gnu.org/archive/html/bug-gnu-utils/2008-01/msg00030.html>.
* bootstrap.conf (gnulib_modules): Add wcwidth.
* src/side.c: Include <wchar.h>.
(print_half_line): Compute number of bytes and print widths of
multibyte characters. Inspired by an alternative solution from
Bruno Haible in

* NEWS: diff -u no longer outputs trailing white space unless the
input data has it. Suggested by Jim Meyering.
* doc/diff.texi (Detailed Unified): Document this.
* src/context.c (pr_unidiff_hunk): Implement this.
Modernize bootstrap procedure to match current gnulib.
* bootstrap: Sync with coreutils bootstrap, except check that
the directory build-aux exists before trying to copy to it.
* bootstrap.conf: New file.
(gnulib_modules): Add config-h, dup2, extensions, fcntl, fdl,
stat-macros, unistd.
* configure.ac: Invoke gl_EARLY and gl_INIT rather than
GNULIB_AUTOCONF_SNIPPET.
(AC_CONFIG_HEADER): Rename config.h to lib/config.h.
(AC_CHECK_HEADERS_ONCE): Don't check for fcntl.h, locale.h,
sys/file.h, unistd.h. We now use the fcntl and unistd modules,
and locale.h can be assumed for any C89 compiler.
(DIFFUTILS_PREREQUISITES): Remove. No longer needed now that
we use the stdint module.
(AC_CHECK_FUNCS_ONCE): Remove dup2, which is no longer needed
now that we use the dup2 module.
(AM_GNU_GETTEXT): Use need-formatstring-macros, and ...
(AM_GNU_GETTEXT_VERSION): specify version 0.15 instead of 0.14.5,
to be consistent with coreutils.
* lib/Makefile.am (noinst_LIBRARIES):
(lib_SOURCES, libdiffutils_a_LIBADD):
(libdiffutils_a_DEPENDENCIES, BUILT_SOURCES, EXTRA_DIST):
(MOSTLYCLEANFILES): Remove; now computed automatically.
(noinst_HEADERS, libdiffutils_a_SOURCES): Just append
our special files now.
* lib/cmpbuf.c: Include config.h unconditionally, since we
no longer define HAVE_CONFIG_H.
* lib/prepargs.c: Likewise.
* src/Makefile.am (LDADD): Use $(LIBINTL), not @LIBINTL@.
(diff_LDADD): Use $(LIB_CLOCK_GETTIME), not @LIB_CLOCK_GETTIME@.
* src/dir.c (dir_read): Use _D_EXACT_NAMLEN, not NAMELEN.
* src/system.h (volatile): Remove, since we assume C89 or better.
Include stat-macros.h.
(S_IRWXU, S_IRWXG, S_IRWXO, S_IRUSR, S_IWUSR):
Remove, since we now use stat-macros.h.
(SEEK_SET, SEEK_CUR): Remove, since we assume C89 or better.
Include unistd.h unconditionally, since we use unistd.
Likewise for fcntl.h.
(dup2): Remove, since we now use dup2.
(O_RDONLY, O_RWDR, O_BINARY): Remove, since we now use
fcntl.
Include dirent.h unconditionally.
(NAMLEN): Remove, replacing with....
(_D_EXACT_NAMLEN): New macro.
Include inttypes.h unconditionally.
(PTRDIFF_MAX, SIZE_MAX, UINTMAX_MAX, strtoumax): Remove, since
we now use inttypes.
Include locale.h unconditionally.
(setlocale): Remove, since we now assume locale.h.
2006-09-04 Jim Meyering <jim@meyering.net>
* src/context.c (print_context_function): Do not print
trailing white space in a context header.
2006-05-09 Paul Eggert <eggert@cs.ucla.edu>
* src/cmp.c (cmp): The previous fix wasn't quite right either, as
it mishandled 'cmp A B >/dev/null' when A is shorter than B and
differs before A's end-of-file, by outputting a bogus EOF message.
Also, it was inefficient if A and B were large.
2006-05-07 Jim Meyering <jim@meyering.net> (tiny change)
Fix bug introduced in 2006-03-09 change:
cmp always exits successfully, when stdout is redirected to /dev/null.
* src/cmp.c (cmp): When there's a difference, arrange to return nonzero
also when comparison_type is the new (from 2006-03-09) type_no_stdout.
2006-05-07 Paul Eggert <eggert@cs.ucla.edu>
* src/context.c (pr_context_hunk, pr_unidiff_hunk):
Prefer fputs or fputc to fprintf, since it's a tad more efficient
with unlocked-IO on glibc. Long ago we avoided fputs to
work around an ancient SunOS bug, but that's no longer relevant.
* src/diff3.c (output_diff3, dotlines, undotlines):
(output_diff3_edscript, output_diff3_merge): Likewise.
This also avoids a gcc -Wformat-security warning reported
by Jim Meyering.
* src/ed.c (print_ed_hunk, print_forward_ed_hunk, print_rcs_hunk):
Likewise.
* src/normal.c (print_normal_hunk): Likewise.
2006-05-06 Paul Eggert <eggert@cs.ucla.edu>
* src/io.c (find_identical_ends): Fix huge performance bug that I
introduced in the 2001-11-25 change: the code to remove the
identical suffix also looked at the trailing sentinel, which meant
the common suffix length was always incorrectly calculated to be
zero. Problem and fix reported by Daniel Hipschman. Instead of
his fix, revert to the pre-2001 code.
* doc/diff.texi: Switch from GFDL 1.1 to 1.2.
2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
* src/system.h (PARAMS, PROTOTYPES): Remove; no longer needed.
(IF_LINT): New macro, to pacify GCC.
* src/analyze.c (diag, compareseq): Use IF_LINT.
* src/cmp.c (cmp): Likewise.
* src/diff3.c (process_diff): Likewise. Also, prefer NULL to 0.
* src/ifdef.c (do_printf_spec, scan_char_literal): Likewise.
* src/sdiff.c (edit): Likewise.
2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
* src/cmp.c (type_no_stdout): New constant.
(main): Use it to avoid bug when the "EOF on foo" message is
generated and stdout is /dev/null.
Problem reported by Vincent Lefevre (Debian bug 356083).
2006-01-04 Paul Eggert <eggert@cs.ucla.edu>
* README-alpha: Describe CVS access better, using the README-alpha
from GNU tar.
* AUTHORS: Simplify list by removing legalisms.
* THANKS: Add Larry Wall, who contributed to manual. Update email
addresses.
* Makefile.am (SUBDIRS): Remove m4. Put lib first, then other
source files, so documentation can rely on programs being built.
* bootstrap: Import changes from Bison bootstrap. Add gettext,
gettime, sh-quote, stat-time, verify, version-etc-fsf modules.
Remove posixver module. Retrieve doc/fdl.texi from gnulib.
Handle gettext.m4 like glibc21.m4. Don't remove po/en.po.
* configure.ac (AC_PREREQ): Bump to 2.59.
(AC_INIT): Bump version to 2.8.7-cvs.

AC_STRUCT_ST_MTIM_NSEC.
(DIFFUTILS_PREREQUISITES): New macro. Call it.
(REGEX_MALLOC): Remove; no longer needed.
(AM_GNU_GETTEXT_VERSION): Now 0.14.15.
(AM_GNU_GETTEXT): Call.
(LIB_CLOCK_GETTIME): Remove; bootstrap now does that.
(AC_FUNC_SETMODE_DOS): Remove.
(AC_CONFIG_FILES): Remove m4/Makefile.
* doc/diff.texi: Use @- at end of lines that should end in white space,
so that Emacs doesn't remove the white space.
(diff Options): "diff -NUM" is a pure extension to POSIX, so support
it unconditionally.
* lib/Makefile.am (noinst_HEADERS): Remove quotesys.h.
(lib_SOURCES): Remove quotesys.c.
(DISTCLEANFILES): Remove.
(EXTRA_DIST): Remove setmode.h, waitpid.c.

(report_identical_files):
Move into struct diffopt. All uses changed.
(exclude_options, compare_files, specify_style, check_stdout):
New arg OPT. All uses changed.
(GDIFF_MAIN): Remove. All uses removed.
(function_regexp_list, ignore_regexp_list): No longer static; now
locals in 'main'.
(main): Set opt.function_regexp, opt.ignore_regexp if using regexps;
all other code now tests these pointers rather than inspecting fastmap
internals.
New local OPT to hold former statics; initialize it.
(init_regexp_list): New function, used by main.
(summarize_regexp_list): Now returns struct re_pattern_buffer *, and
assumes reglist->regexps is not NULL. All uses changed.

All uses changed.
(pr_context_label, pr_context_header,
print_context_script, find_function, find_hunk, mark_ignorable,

last line is a single-dot line.
2004-06-30 Paul Eggert <eggert@cs.ucla.edu>

Don't include <stdbool.h>, since setmode.h now does this.
Include setmode.h first, to catch interface errors.
Assume HAVE_SETMODE_DOS is defined.

(XGETTEXT): Restore from pre-2004-04-12 version. This fixes
a bug that lost many msgids in doc/diffutils.pot.
* bootstrap: New file.
* exgettext: Don't generate a temporary file, as this runs afoul
of "make distcheck" which operates with read-only directories.
* Makefile.am (EXTRA_DIST): Add bootstrap.
Remove config/config.rpath as it is deduced automatically these days.
2004-04-12 Paul Eggert <eggert@twinsun.com>
* NEWS, configure.ac (AC_INIT): Version 2.8.6.
* NEWS: Add news for 2.8.4, 2.8.6.

AC_HEADER_STAT, AC_FUNC_VPRINTF, jm_FUNC_GLIBC_UNLOCKED_IO,
jm_FUNC_GNU_STRFTIME, jm_FUNC_MALLOC, jm_FUNC_REALLOC,
jm_PREREQ_C_STACK, jm_PREREQ_ERROR, jm_PREREQ_HARD_LOCALE,
jm_PREREQ_QUOTEARG, jm_PREREQ_REGEX, AC_FUNC_FNMATCH_GNU, jm_AC_DOS):
Remove; not needed here, as our files don't use them directly
or we rely on gnulib modules.

Don't treat files as binary if !binary.
(set_mtime_to_now): Use 0, not NULL.

(next_line0, next_line1): New vars.
(print_ifdef_script, print_ifdef_hunk):
Use them to fix line-number computation bug.
* src/io.c (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.
* src/util.c (lines_differ): Likewise.
* src/sdiff.c: 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.
* src/system.h (S_IRWXU, S_IRWXG, S_IRWXO): Define if not defined.
(S_IXUSR, S_IXGRP, S_IXOTH): Remove.

(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.
* src/util.c (begin_output): Fix bug: 0 wasn't cast to char * arg,
which led to undefined behavior on 64-bit hosts.

2004-03-15 Paul Eggert <eggert@twinsun.com>
* src/cmp.c (main): Don't consider two files with the same name to
be the same, if their initial skip values differ. This fixes a
bug reported by Hideki Iwamoto in
<http://mail.gnu.org/archive/html/bug-gnu-utils/2004-03/msg00024.html>.
2004-03-11 Paul Eggert <eggert@twinsun.com>
* src/analyze.c (diag): Return void, not lin, since the return
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.
2004-02-09 Paul Eggert <eggert@twinsun.com>

Bug reported by Chris Bainbridge.
2002-10-13 Paul Eggert <eggert@twinsun.com>
* src/Makefile.am (MOSTLYCLEANFILES): Add paths.ht.
(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>.
2002-06-27 Paul Eggert <eggert@twinsun.com>
