2002-05-28  Jim Meyering  <[e-mail]>

	* readdir.m4 (jm_FUNC_READDIR): Undefine `mkdir', not `rmdir'.
	Reported by Volker Borchert.

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

	* gettimeofday.m4 (AC_FUNC_GETTIMEOFDAY_CLOBBER): Also replace
	localtime.

	* readdir.m4 (jm_FUNC_READDIR): Undefine `rmdir' so we don't try to

	Reported by Volker Borchert.

2002-04-30  Jim Meyering  <[e-mail]>

	* prereq.m4 (jm_PREREQ): Add jm_PREREQ_STAT.

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

	* prereq.m4 (jm_PREREQ_HARD_LOCALE): Check for stdlib.h.
	Do not check for alloca.h (no longer used) or stdbool.h (was never
	used?).  Add AM_C_PROTOTYPES since hard-locale.h uses it.

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

	* prereq.m4 (jm_PREREQ_SIG2STR): Remove; all callers changed.

2002-04-29  Jim Meyering  <[e-mail]>

	* jm-macros.m4 (jm_MACROS): Remove use of AC_FUNC_STRNLEN.
	* prereq.m4: Add jm_PREREQ_STRNLEN.
	Use AC_FUNC_STRNLEN here instead.

	With autoconf-2.53a, it's part of AC_PROG_CC.

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

	* jm-macros.m4 (jm_MACROS): Add AC_REPLACE_FUNCS(sig2str).
	* prereq.m4 (jm_PREREQ): Add jm_PREREQ_SIG2STR.

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

	* prereq.m4 (jm_PREREQ_HARD_LOCALE): New macro.
	(jm_PREREQ): Use it.

	* getloadavg.m4: Check for these headers: locale.h unistd.h
	mach/mach.h fcntl.h.
	Check for this function: setlocale.

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

	* prereq.m4 (jm_PREREQ_READUTMP): Also check for these members:
	ut_pid, ut_id, ut_exit.

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

	* ls-mntd-fs.m4 (checking for getmntinfo function...): Remove now-bogus
	check for f_type in sys/mount.h.  Instead, just test for the existence
	of the getmntinfo function.  Needed for Darwin 5.3.

	* dirfd.m4 (UTILS_FUNC_DIRFD): Also detect when dirfd is a macro.
	This is necessary at least on Darwin 5.3.

	* jm-macros.m4: Don't AC_REPLACE(strnlen), now that we use
	AC_FUNC_STRNLEN.  Otherwise, we'd end up putting two copies of strnlen.o
	in the library, and that makes some versions of ranlib object.

2002-04-09  Jim Meyering  <[e-mail]>

	* malloc.m4: (jm_FUNC_MALLOC): Change the `checking ...' message
	to be more precise.  Rather than saying we're checking whether the
	function `works', say what we're testing.
	* realloc.m4 (jm_FUNC_REALLOC): Likewise.
	Reported by Bruno Haible.

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

	* jm-macros.m4 (jm_MACROS): Do not replace stime; no longer used.
	Check for clock_settime.

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

	* acl.m4: New file.
	* jm-macros.m4 (jm_MACROS): Require AC_FUNC_ACL.
	Do not check for acl or sys/acl.h, as AC_FUNC_ACL does that now.

2002-02-16  gettextize  <[e-mail]>

	* codeset.m4: Upgrade to gettext-0.11.
	* gettext.m4: Upgrade to gettext-0.11.

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

	* jm-macros.m4 (jm_MACROS): Require autoconf-2.52g.
	* strnlen.m4: Remove file, now that it's part of autoconf.

2002-01-22  Paul Eggert  <[e-mail]>

	* jm-macros.m4 (jm_MACROS): Require AC_FUNC_FSEEKO.

2002-01-19  Jim Meyering  <[e-mail]>

	* jm-macros.m4 (jm_MACROS): Use AC_FUNC_STRNLEN.
	Remove useless quotes: DF_PROG="df".
	* strnlen.m4: New file.

2001-12-14  Jim Meyering  <[e-mail]>

	* jm-macros.m4 (jm_MACROS): Check for iswspace.
	Suggestion from Bruno Haible.

2001-11-20  Jim Meyering  <[e-mail]>

	* mkstemp.m4 (UTILS_FUNC_MKSTEMP): Update comment to reflect that
	SunOS4.1.4 and solaris2.5.1 lose, too.

2001-11-19  Jim Meyering  <[e-mail]>

	* mkstemp.m4 (UTILS_FUNC_MKSTEMP): Don't bother with a temporary
	directory.  Use "conftestXXXXXX" as the template.
	Suggestion from Paul Eggert.

	* mkstemp.m4 (UTILS_FUNC_MKSTEMP): Close each descriptor immediately,
	so the test doesn't mistakenly hit the max-open-files limit.

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

	* prereq.m4 (jm_PREREQ_TEMPNAME): Check for declaration of getenv.

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

	* mkstemp.m4 (UTILS_FUNC_MKSTEMP): New file and macro.
	Prompted by a report from Bob Proulx.

	* jm-macros.m4 (jm_MACROS): Don't test for mkstemp here.
	Instead, require UTILS_FUNC_MKSTEMP.

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

	* jm-macros.m4 (jm_MACROS): Remove code to set POW_LIBM.
	Now, that's done as part of AC_FUNC_STRTOD.

2001-10-22  Paul Eggert  <[e-mail]>

	* jm-winsz1.m4 (jm_WINSIZE_IN_PTEM): Do not define
	WINSIZE_IN_PTEM if <termios.h> defines struct winsize.

2001-11-10  Jim Meyering  <[e-mail]>

	* prereq.m4 (jm_PREREQ_PHYSMEM): New function.
	(jm_PREREQ): Use it.

2001-11-09  Jim Meyering  <[e-mail]>

	* jm-macros.m4: Require autoconf-2.52f.
	(AC_FUNC_ERROR_AT_LINE, AC_FUNC_OBSTACK, AC_FUNC_STRTOD):
	Use these AC_-prefixed names, not the AM_-prefixed ones.

	* afs.m4 (jm_AFS): Quote the body.  Patch by Akim Demaille.

2001-11-04  Jim Meyering  <[e-mail]>

	* fpending.m4: Remove unused cruft that saved, set, and restored $DEFS.

2001-11-03  Jim Meyering  <[e-mail]>

	* jm-glibc-io.m4n (jm_FUNC_GLIBC_UNLOCKED_IO): Quote first arg
	of AC_DEFUN.

	* dirfd.m4 (UTILS_FUNC_DIRFD): Rework so dirfd.c doesn't have to
	know the name of the variable in the macro definition.

2001-11-01  Jim Meyering  <[e-mail]>

	* dirfd.m4 (UTILS_FUNC_DIRFD): New macro.
	* jm-macros.m4 (jm_MACROS): Require UTILS_FUNC_DIRFD.

2001-10-20  Paul Eggert  <[e-mail]>

	* error.m4 (jm_PREREQ_ERROR):
	Do not invoke AC_CHECK_FUNCS with strerror_r, as
	AC_FUNC_STRERROR_R does that.
	Check for strerror declaration.

	* strerror_r.m4: Add copyright notice, as nontrivial m4 files
	are supposed to have them these days.
	(AC_FUNC_STRERROR_R): Always do char* test, so that it gets cached.
	Merge changes from latest Autoconf CVS.
	Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
	and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
	POSIX decided to standardize on the int flavor of strerror_r.

2001-09-30  Jim Meyering  <[e-mail]>

	* ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): See if
	`struct fsstat' has the `f_fstypename' member.
	Use that to define FS_TYPE, which is now used to make
	the getfsstat link test tighter.

2001-09-29  Jim Meyering  <[e-mail]>

	* ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS)
	[one-argument getmntent function]): Include stdio.h before mntent.h.
	SunOS4.1.x needs it for the declaration of `FILE'.
	Patch by Volker Borchert.

	* ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS)
	Check for these headers: sys/param.h sys/ucred.h sys/mount.h
	sys/fs_types.h, and make the link-test for getfsstat guard #include
	directives with appropriate #if HAVE_*_H tests so that we can
	detect getfsstat on Apple Darwin1.3.7 systems.
	Reported by Nelson Beebe.
	Fix harmless typo in cache variable name: s/getsstat/getfsstat/.

2001-09-28  Paul Eggert  <[e-mail]>

	Fix bug reported by Petter Reinholdtsen for HP-UX 10.20, which
	#defines strtoimax.  Also treat the other strto* functions
	like strtoimax.

	* xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX):
	Check for strtoul and strtoumax,
	as those declarations are made even in the signed case.
	* xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX):
	Likewise, for strtol and strtoimax.

2001-09-24  Jim Meyering  <[e-mail]>

	* gettext.m4: Use the version from gettext-0.10.40, not CVS.

2001-09-23  Jim Meyering  <[e-mail]>

	* ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Add a compile-test
	instead of the mere test for existence of mntent.h.  The latter
	would get a false-positive on AIX 3.4 systems.
	In the outer getmntent if-block, don't die if neither of the getmntent
	tests succeeds.  Instead, just fall through and continue with the
	remaining tests.

2001-09-22  Jim Meyering  <[e-mail]>

	* gettext.m4: New file.  From gettext.
	* lcmessage.m4: Sync with gettext -- this changes only comments.
	* progtest.m4: Likewise
	* isc-posix.m4: Decrement serial number to sync with gettext.
	* glibc21.m4: Likewise.

	* libintl.m4: Remove.  No longer used.

2001-09-20  Jim Meyering  <[e-mail]>

	* xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX): Check for declaration of
	strtoimax.
	* xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): Check for declaration of
	strtoumax.

2001-09-17  Jim Meyering  <[e-mail]>

	* chown.m4, fstypename.m4, getgroups.m4, gettimeofday.m4,
	* jm-mktime.m4, lstat.m4, malloc.m4, memcmp.m4, mkdir-slash.m4,
	* nanosleep.m4, putenv.m4, readdir.m4, realloc.m4, rename.m4,
	* st_dm_mode.m4, stat.m4, strerror_r.m4, timespec.m4, utimbuf.m4,
	* utimes.m4: Use AC_DEFINE rather than AC_DEFINE_UNQUOTED,
	whenever the right hand side need not be expanded by the shell.

2001-09-16  Paul Eggert  <[e-mail]>

	* fnmatch.m4 (jm_FUNC_FNMATCH): Remove test for GNU C
	library.  It's not correct, as some older glibcs are buggy.
	fnmatch wasn't fixed until glibc 2.2.

	Use AC_DEFINE, not AC_DEFINE_UNQUOTED, as there's no
	special shell magic here.

2001-09-16  Jim Meyering  <[e-mail]>

	* mkdir-slash.m4 (UTILS_FUNC_MKDIR_TRAILING_SLASH): New file/macro.
	* jm-macros.m4: Require it.

2001-09-15  Jim Meyering  <[e-mail]>

	* jm-macros.m4: Check for help2man.

2001-09-11  Jim Meyering  <[e-mail]>

	* host-os.m4 (UTILS_HOST_OS): New file/macro.
	The body, by Paul Eggert, was moved here from configure.in.
	* jm-macros.m4: Require UTILS_HOST_OS.

2001-09-04  Paul Eggert  <[e-mail]>

	* prereq.m4 (jm_PREREQ_XREADLINK): New macro.
	(jm_PREREQ): Use it.

2001-09-03  Paul Eggert  <[e-mail]>

	* prereq.m4 (jm_PREREQ_XGETCWD): Check for limits.h and
	sys/param.h, as pathmax.h includes them.
