2002-07-20  Jim Meyering  <[e-mail]>

	* xmalloc.c: Adjust to work with new autoconf macros, AC_FUNC_MALLOC
	and AC_FUNC_REALLOC: test #ifndef HAVE_MALLOC/HAVE_REALLOC.

	* gettext.h: Upgrade to gettext-0.11.3.

2002-07-13  Bruno Haible  <[e-mail]>

	* xstat.in: Include <string.h>.
	* mountlist.c: #undef MNT_IGNORE before defining it, to avoid warning
	on FreeBSD.

2002-07-09  Jim Meyering  <[e-mail]>

	* mountlist.h (ME_DUMMY): Don't count entries of type `auto' as dummy
	ones.  At least on GNU/Linux systems, `auto' means something else.
	From Michael Stone.

2002-07-01  Jim Meyering  <[e-mail]>

	* c-stack.c: Include sys/time.h.
	From Volker Borchert.

2002-06-11  Paul Eggert  <[e-mail]>

	* fnmatch.c, fnmatch_loop.c (WIDE_CHAR_SUPPORT):
	New macro.  Use it uniformly instead of
	(defined HAVE_WCTYPE_H && defined HAVE_WCHAR_H).
	It also uses HAVE_BTOWC, to fix a porting bug on Solaris 2.5.1
	reported by Vin Shelton.

2002-06-22  Jim Meyering  <[e-mail]>

	* fnmatch.c (ISASCII, ISPRINT): Undefine, to avoid warning about
	redefinition due to Solaris5.6's definition in /usr/include/sys/euc.h.

2002-06-22  Paul Eggert  <[e-mail]>

	* c-stack.h (segv_handler, c_stack_action) [! defined SA_SIGINFO]:
	Do not assume SA_SIGINFO behavior.
	Bug reported by Jim Meyering on NetBSD 1.5.2.

2002-06-22  Jim Meyering  <[e-mail]>

	* c-stack.c, c-stack.h: New files, from diffutils-2.8.2.

	* exitfail.c, exitfail.h: Likewise.
	* Makefile.am (libfetish_a_SOURCES): Add exitfail.c and exitfail.h.

	* Makefile.am (libfetish_a_SOURCES): Add fnmatch_.h in place
	of fnmatch.h.
	(EXTRA_DIST): Add fnmatch_loop.c.
	(libfetish_a_SOURCES): Add c-stack.c and c-stack.h.

	* fnmatch_loop.c: New file, from diffutils-2.8.2.
	* fnmatch.c: Update from diffutils-2.8.2.
	* fnmatch_.h: New file.  From diffutils-2.8.2.
	* fnmatch.h: Remove file.

2002-06-18  Paul Eggert  <[e-mail]>

	* file-type.h: Report an error if neither S_ISREG nor
	S_IFREG is defined, instead of using a test specific to glibc
	2.2.  This should be safe, since POSIX requires S_ISREG and
	Unix Version 7 had S_IFREG.  We don't need to check for
	<sys/types.h> since we don't use any symbols that it defines.

2002-06-15  Jim Meyering  <[e-mail]>

	* file-type.h (FILE_TYPE_H): Guard entire contents with #ifndef.
	For GNU libc 2.2 and newer, ensure that <sys/types.h> and <sys/stat.h>
	have been included before this file.

2002-06-13  Richard Dawe  <[e-mail]>

	* Makefile.am (lstat.c, stat.c, .sin.sed): Use t-$@, rather than $@-t,
	so that each temporary file name is unique and valid in the first
	8 characters, for operation under DOS.

2002-06-15  Jim Meyering  <[e-mail]>

	Work even with DJGPP 2.03, which lacks support for symlinks.
	From Richard Dawe.
	* xstat.in (S_ISLNK): Define to 0 if neither S_ISLNK nor S_IFLNK
	is defined.
	* lchown.c (S_ISLNK): Likewise.

2002-06-14  Jim Meyering  <[e-mail]>

	* file-type.h: Use the version from diffutils-2.8.2.
	* file-type.c: Likewise.

2002-05-27  Jim Meyering  <[e-mail]>

	Fix a problem seen only on nonconforming systems whereby ls.c's
	use of localtime, and then of gettimeofday would cause trouble:
	the localtime call used to initialize rpl_gettimeofday's save
	mechanism would clobber ls's current local time information so
	that in any long listing the first file would always be listed
	with date 1970-01-01.  Analysis by Volker Borchert.

	* gettimeofday.c (localtime): Undefine.
	(rpl_localtime): New function.

2002-05-22  Jim Meyering  <[e-mail]>

	* Makefile.am (libfetish_a_SOURCES): Add file-type.c and file-type.h.
	* file-type.h: New file.
	* file-type.c (file_type): New file/function.  Extracted from diffutils.

2002-04-29  Paul Eggert  <[e-mail]>

	* hard-locale.c: Upgrade to version used in GNU Diffutils 2.8.1.

2002-04-28  Paul Eggert  <[e-mail]>

	* sig2str.h (SIGNUM_BOUND): Do not use WTERMSIG, to avoid
	depending on <sys/wait.h> and WTERMSIG.  Default to 64 instead
	of 127, since 64 is the largest conceivable number for ancient
	nonstandard hosts.
	* sig2str.c: Do not include <sys/wait.h>; no longer needed.

2002-04-28  Jim Meyering  <[e-mail]>

	* sig2str.c (WTERMSIG): Remove definition (unused).

2002-04-28  Paul Eggert  <[e-mail]>

	* sig2str.h, sig2str.c: New files.
	* Makefile.am (libfetish_a_SOURCES): Add sig2str.h.

2002-04-24  Jim Meyering  <[e-mail]>

	* gettext.h: New file, from Gettext.
	* Makefile.am (INCLUDES): Remove -I../intl.
	(libfetish_a_SOURCES): Add gettext.h.

2002-04-16  Jim Meyering  <[e-mail]>

	* readutmp.h (UT_TYPE): Remove definition (now in who.c).
	(HAVE_STRUCT_XTMP_UT_EXIT, HAVE_STRUCT_XTMP_UT_ID): Define.
	(HAVE_STRUCT_XTMP_UT_PID, HAVE_STRUCT_XTMP_UT_TYPE): Define.

2002-04-12  Jim Meyering  <[e-mail]>

	* rename.c: Mention that this wrapper is needed also on
	mips-dec-ultrix4.4 systems.

2002-03-02  Jim Meyering  <[e-mail]>

	* gettime.c (gettime): Test HAVE_CLOCK_GETTIME,
	not HAVE_CLOCK_SETTIME.

2002-02-27  Paul Eggert  <[e-mail]>

	* nanosleep.h: Rename to....
	* timespec.h: New name for nanosleep.h.  All uses changed.

	* settime.c: New file.
	* stime.c: Remove.

	* Makefile.am (libfetish_a_SOURCES): Add gettime.c, settime.c,
	timespec.h.  Remove nanosleep.h.

2002-02-25  Paul Eggert  <[e-mail]>

	* acl.c, acl.h: New files.
	* Makefile.am (libfetish_a_SOURCES): Add acl.h, acl.c.

2002-02-24  Jim Meyering  <[e-mail]>

	* strnlen.c (strnlen): Define-away/undef so that an inconsistent
	prototype in string.h (on at least AIX4.3.2.0 w/gcc-2.95.3) doesn't
	cause trouble.  Reported by Nelson Beebe.

2002-02-23  Paul Eggert  <[e-mail]>

	* path-concat.c (xpath_concat): Reorder code to pacify
	compilers that don't know that xalloc_die never returns.

2002-02-20  Jim Meyering  <[e-mail]>

	(fwrite_success_callback): New declaration.
	* unicodeio.c (unicode_to_mb): New function, extracted from
	print_unicode_char. Call failure callback instead of error.
	(fwrite_success_callback): New function.
	(exit_failure_callback): New function.
	(fallback_failure_callback): New function.
	(print_unicode_char): Call unicode_to_mb.

2002-01-26  Jim Meyering  <[e-mail]>

	* Makefile.am (getdate$U.o): Depend on unlocked-io.h.

2002-01-22  Jim Meyering  <[e-mail]>

	* Makefile.am (Makefile): Don't depend on $(BUILT_SOURCES).
	Otherwise, some versions of automake would omit the rule that makes
	Makefile from Makefile.in.

2001-01-21  Paul Eggert  <[e-mail]>

	* xmemcoll.h, xmemcoll.c: New files.
	* Makefile.am (libfetish_a_SOURCES): Add them.

	(memcoll): Set errno to zero if there is no error.

	* quotearg.c (quotearg_buffer_restyled):

	Bison (as of version 1.31) no longer papers over that mistake.

2002-02-14  Paul Eggert  <[e-mail]>

	* backupfile.c (ISDIGIT): Comment fix.
	* getdate.y (ISDIGIT): Likewise.

2001-01-19  Paul Eggert  <[e-mail]>

	* closeout.c (close_stdout_status): If ferror (stdout), do
	not silently exit merely because the output buffer happens to
	have nothing pending.

2001-12-18  Paul Eggert  <[e-mail]>

	See the big note in ../ChangeLog.
	* human.c (suffixes): Prefer K to k for 1024.
	(generate_suffix_backwards): New function.
	(human_readable_inexact): Use it.
	* xstrtol.c (__xstrtol): If there is no number but there
	is a valid suffix, assume 1.  "MB" now means decimal, "MiB" binary.
	Accept 'K' as well as 'k'.

2001-12-15  Jim Meyering  <[e-mail]>

	* regex.h (__restrict_arr): Update from libc.

	* mountlist.h (ME_REMOTE): Recognize file systems of type smbfs
	as `remote' if the name starts with `//'.  Suggested by Michael Stone.
	(STREQ): Define.

2001-12-10  Jim Meyering  <[e-mail]>

	* linebuffer.c: Remove explicit declarations of xmalloc and xrealloc,
	Instead, include "xalloc.h".
	(initbuffer): Don't cast xmalloc return value to char*.
	(readline): Reword comment.
	Don't cast xrealloc return value to char*
	Return NULL, not 0.

2001-12-09  Jim Meyering  <[e-mail]>

	* modechange.c (mode_compile): Add cast to avoid pedantic warning about
	`signed and unsigned type in conditional expression'.
	* posixtm.c (posix_time_parse): Likewise.

	* xreadlink.c (xreadlink): Add cast to avoid a pedantic warning.

	* readtokens.c (readtoken): Declare an index to be of type unsigned

	* strftime.c (my_strftime_localtime_r): Include this function
	definition in the `#if ! HAVE_TM_GMTOFF' block.

	* xgethostname.c: Remove declarations of xmalloc and xrealloc.
	Include xalloc.h instead.

2001-12-02  Jim Meyering  <[e-mail]>

	* tempname.c: Don't declare getenv, thus reverting the change of
	2001-11-18.  It's no longer necessary, now that stdlib.h is always
	included.

	* regex.c [!__BOUNDED_POINTERS__]: Define away __bounded,
        __unbounded, and __ptrvalue.  Reported by Uwe H. Steinfeld.

2001-11-30  Akim Demaille  <[e-mail]>

	* xstrdup.c: Include xalloc.h, so that xstrdup is declared
	before being defined.

2001-11-27  Paul Eggert  <[e-mail]>

	First arg is int, not unsigned.
	* quotearg.c (quotearg_n, quotearg_n_style): Likewise.
	(SIZE_MAX, UINT_MAX): New macros.
	(quotearg_n_options): Abort if N is negative.
	Avoid overflow check on hosts where size_t is 64 bits and int
	is 32 bits, as overflow is impossible there.
	Fix off-by-one typo that caused unnecessary reallocation.

2001-11-27  Jim Meyering  <[e-mail]>

	* tempname.c: Merge with version from libc.
	* regex.c: Likewise.

	* tempname.c: Include stdlib.h unconditionally.  On some old systems
	for which STDC_HEADERS is 0, it was not included, resulting in a
	warning about an integer-to-pointer conversion problem with getenv.
	Reported by Volker Borchert.

2001-11-26  Jim Meyering  <[e-mail]>

	* gtod.h: Remove file.
	* Makefile.am (libfetish_a_SOURCES): Remove gtod.h.
	* gettimeofday.c: Don't include gtod.h.
	(GTOD_init): Remove function.
	(rpl_gettimeofday): Do its job here instead, rather than aborting.
	Suggestion from Volker Borchert.

2001-11-23  Jim Meyering  <[e-mail]>

	* hash.h (struct hash_table): Don't define here.  Merely declare it.

2001-11-22  Jim Meyering  <[e-mail]>

	* hash.h: Bracket contents of file with #ifndef HASH_H_ ... #endif.

2001-11-18  Paul Eggert  <[e-mail]>

	* tempname.c (TMP_MAX): Remove; no longer needed.
	(TEMPORARIES): New macro.
	(__gen_tempname): Use TEMPORARIES rather than TMP_MAX.  This
	removes an artificial limitation (e.g. HP-UX 10.20, where
	TMP_MAX is 17576).

2001-11-18  Jim Meyering  <[e-mail]>

	* tempname.c [!HAVE_DECL_GETENV]: Declare getenv to avoid warning
	on SunOS4.

	* Makefile.am (Makefile): Depend on $(BUILT_SOURCES), so those
	files will be created before anything else.

2001-11-17  Jim Meyering  <[e-mail]>

	* modechange.c (mode_adjust): Fix error introduced on 1999-04-26
	that made e.g., `chmod a=,o=w,g=o F' cause F to be group readable
	rather than group writable.  Patch by Juan F. Codagnone.

	* readtokens.c: Remove explicit declarations of xmalloc and xrealloc,
