	AC_COMPILE_CHECK, AC_TEST_PROGRAM, AC_TEST_CPP): Remove $DEFS
	from cc and cpp command lines; include "confdefs.h" in test
	files.
	(AC_DEFINE): Append a #define to confdefs.h.

Wed Aug 11 18:52:41 1993  David J. MacKenzie  ([e-mail])

	* acspecific.m4 (AC_FIND_X): Don't set x_includes if it's

Fri Jul 30 18:08:30 1993  Roland McGrath  ([e-mail])

	* autoheader.sh (syms, headers, funcs, libs): Run values through
	sort|uniq to remove duplicates.

Wed Jul 28 00:02:34 1993  David J. MacKenzie  ([e-mail])

	* Makefile.in (config.status): Run config.status --recheck,
	not configure.

	exist before choosing them in hopes they will define getloadavg.

	* autoheader.sh (frob): Put $2 and $3 in the expansion of
	AC_HAVE_LIBRARY, so AC_DEFINE there is noticed.

Mon Jul 26 14:21:33 1993  David J. MacKenzie  ([e-mail])

	* acspecific.m4 (INT_16_BITS): Check the obvious way, so it
	doesn't pick up machines with 64 bit longs.

Mon Jul 26 14:01:38 1993  Roland McGrath  ([e-mail])

	* acspecific.m4 (AC_GETLOADAVG): Check for -lelf with

	AC_HAVE_LIBRARY.

Mon Jul 26 13:55:17 1993  Roland McGrath  ([e-mail])

	in INCROOT and USRLIBDIR, instead of using sed.
	From [e-mail] (Jack Woychowski).

	* acgeneral.m4 (AC_DEFINE): When printing value verbosely, use
	double quotes and AC_DEFINE_QUOTE, like we do when assigning
	the value, so shell variables get expanded the same way.

	* acgeneral.m4 (AC_REVISION): New macro.
	From [e-mail] (Garrett Wollman).

	* acgeneral.m4 (AC_DEFINE): Add newline before open brace.

Thu Jul 22 17:07:15 1993  Roland McGrath  ([e-mail])

Wed Jul 14 22:44:25 1993  Roland McGrath  ([e-mail])

	* acconfig.h: Restore blank lines between paragraphs.

	* autoheader.sh (libs): New variable and frob to set it from
	AC_HAVE_LIBRARY uses.  Produce #undef HAVE_* for each $libs.

Tue Jul 13 19:03:46 1993  David J. MacKenzie  ([e-mail])

	* acconfig.h: Sort the entries, like the comment says.

	* acspecific.m4 (AC_GETLOADAVG): Only check for the AIX library
	once, looking in both local and system dirs.
	Consolidate SVR4 and Solaris cases.

Sun Jul 11 00:43:51 1993  David J. MacKenzie  ([e-mail])

	-lutils, and requires -lkvm too.
	Check for local AIX library using AC_HAVE_LIBRARY, not
	AC_COMPILE_CHECK.
	Un-nest some conditionals.  Stop checking once we've
	found a way to get getloadavg.

Thu Jul  8 20:21:28 1993  David J. MacKenzie  ([e-mail])

	* Makefile.in: Remove rules for making *.conf; make
	Autoconf's configure script semi-normally.

Wed Jul  7 14:37:35 1993  David J. MacKenzie  ([e-mail])

	* autoheader.sh (--help): Print help message to stdout and exit 0.
	(--version): Exit after printing version number.

	isn't smaller than double, as in Ultrix 4.[23] cc.

	* acgeneral.m4 (AC_REPLACE_FUNCS): Include ctype.h in the test
	program to get stubs.

Tue Jul  6 19:15:17 1993  David J. MacKenzie  ([e-mail])

	* acspecific.m4 (AC_GETLOADAVG): Try ls -L first, in case

	* acspecific.m4 (AC_MINUS_C_MINUS_O): Remove spurious `then'.

Fri Jun 25 23:16:42 1993  Paul Eggert  ([e-mail])

	* acspecific.m4 (AC_CONST): Replace `p = <const char** expr>'
	with `ccp = <const char** expr>'; the former wasn't ANSI C, and
	was causing working compilers to be rejected.

Fri Jun 25 13:26:34 1993  Noah Friedman  ([e-mail])

	* acspecific.m4 (AC_LONG_FILE_NAMES): Redirect rm's stderr to
	/dev/null.

Thu Jun 24 15:58:04 1993  Noah Friedman  ([e-mail])

	* autoconf.sh, autoheader.sh, acgeneral.m4 (AC_PREPARE): Undo
	change of Jun 16 1993.  Only set `LANG' and `LC_ALL' to "C" if
	already set.

Sat Jun 19 00:01:51 1993  Jim Meyering  ([e-mail])

	* acgeneral.m4: Undefine m4's `format' builtin.
	* acspecific.m4 (AC_HAVE_POUNDBANG): Make conftest executable,
	but not necessarily writable by group or other.

Thu Jun 17 21:10:33 1993  Noah Friedman  ([e-mail])

	* acspecific.m4 (AC_PROG_CPP): Put double quotes around ${CC-cc},
	not single quotes.
	If --verbose option given, say what CPP is being set to.

Wed Jun 16 17:50:00 1993  Jim Blandy  ([e-mail])

	* acspecific.m4 (AC_PROG_CPP): Make sure that `cc -E` doesn't
	run the program through the C compiler too.  Bob Olson
	<[e-mail]> says it does on the NeXT.

Wed Jun 16 16:17:05 1993  Noah Friedman  ([e-mail])

	* autoconf.sh, autoheader.sh, acgeneral.m4 (AC_PREPARE): Always set
	`LANG' and `LC_ALL' environment variables to `C'.

Fri Jun 11 14:29:31 1993  Roland McGrath  ([e-mail])

	* acspecific.m4 (AC_MINUS_C_MINUS_O): Test that cc works at all,
	and only test it for -c -o if it does.

Tue Jun  8 01:47:22 1993  Paul Eggert  ([e-mail])

	* acgeneral.m4 (AC_OUTPUT): The line
	  DEFS="`echo \"$DEFS\" | sed 's%[&\\\]%\\\&%g'`"
	doesn't work in some shells, which don't allow nesting
	\"\" inside `` inside "", and which don't unescape \\\& in the
	expected (?) way.  Also, some versions of echo interpret
	backslashes inside $DEFS.  Put $DEFS into a temporary file
	to avoid these portability minefields.

Mon Jun  7 20:11:50 1993  Roland McGrath  ([e-mail])

	* acspecific.m4 (AC_GETLOADAVG): In setting KMEM_GROUP, use new sed
	magic from friedman which should win with both meanings of ls -lg.

Mon Jun  7 06:48:49 1993  Noah Friedman  ([e-mail])

	* Makefile.in (dist): Change gzipped tar file extension to `.gz'.
	Use explicit --gzip option to tar to make sure tar uses the right
	compression program (or else exits from failure to understand the
	option).

	* acgeneral.m4 (AC_OUTPUT): Don't split sed expr for exec_prefix
	across two lines, since not all versions of sed understand that.

	* acspecific.m4 (AC_HAVE_POUNDBANG): Complete rewrite which doesn't
	depend on csh.

Tue Jun  1 03:06:28 1993  Noah Friedman  ([e-mail])

	* Version 1.4.1 (not announced to the general public, but
	a snapshot was put on the June '93 GNU CDROM).

	* Makefile.in (dist): If ln fails (e.g. because of cross-device
	links), mention on stdout that file is being copied.

	* acgeneral.m4 (AC_PREPARE): Use `[$]*' in assignment to
	configure_args to get shell positional args, rather than m4 args to
	AC_PREPARE.
	(AC_OUTPUT): Use `configure_args' in config.status
	when invoked with --recheck, rather than $*.

Mon May 31 13:12:56 1993  Paul Eggert  ([e-mail])

	* acspecific.m4 (AC_LONG_FILE_NAMES): rm $dir/conftest*,
	not conftest*.

Mon May 31 04:18:18 1993  Roland McGrath  ([e-mail])

	* acgeneral.m4 (AC_HAVE_LIBRARY): Quote libname in define.

Sun May 30 19:52:24 1993  Roland McGrath  ([e-mail])

	* acspecific.m4 (AC_SETVBUF_REVERSED): Pass (char *) main to
	setvbuf instead of zero.

Thu May 27 20:30:53 1993  Roland McGrath  ([e-mail])

	* acgeneral.m4 (AC_PREPARE): Save $* in shell var `configure_args'.
	(AC_OUTPUT): Use $configure_args in place of $*.

Wed May 26 16:19:51 1993  Noah Friedman  ([e-mail])

	* autoconf.texi (AC_PROG_INSTALL): Doc fix.
	(Automatic Remaking): Put code fragment in @example ... @end example.

Mon May 24 15:46:47 1993  Roland McGrath  ([e-mail])

	* autoheader.sh (frob): Redefine AC_CONFIG_HEADER to set shell
	variable `config_h'.
	(config_h): New variable, initialize to "config.h" before frobbing.
	(final output): Write ${config_h}.in.

Sat May 22 17:45:19 1993  Noah Friedman  ([e-mail])

	* Version 1.4 released.

Thu May 20 20:25:45 1993  Jim Blandy  ([e-mail])

	* acgeneral.m4 (AC_IDENTITY): New function.
	(AC_DEFINE_UNQUOTED): Use it to fix this; due to a
	misunderstanding of m4, this was using its first argument as
	the definition.

Thu May 20 09:21:55 1993  Jim Meyering  ([e-mail])

	* acspecific.m4 (AC_ALLOCA) [find_stack_direction]: Return the
	value from the recursive call.  If it worked before, it was by luck.
	From Bruno Haible <[e-mail]>.

Tue May 18 23:40:21 1993  Noah Friedman  ([e-mail])

	* acspecific.m4 (AC_STDC_HEADERS): Require AC_PROG_CPP.

Mon May 17 18:01:09 1993  Karl Berry  ([e-mail])
