	longer required can still cause errors.
	Reported by Alexandre Duret-Lutz.

	* bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
	to frozen files in @ARGV, as @ARGV must remain being a list of

	(&up_to_date): If a file that was included according to the cache
	is no longer there, then the output is out dated.

	format, so that Emacs' compile mode understands us.

	if some file was changed instead of `print'.
	* bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

	(AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
	(_AC_CHECK_HEADER_NEW): Rename as...

	From Sam Varshavchik.

2002-10-08  Akim Demaille  <[e-mail]>

	* bin/autoreconf.in (&autoreconf): Run autopoint before the first
	aclocal invocation, as Gettext macros might not be visible to
	aclocal.
	Instead of blindly running autopoint, scan configure.ac (not the
	traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
	Reported by Paul D. Smith.

2002-10-08  Paul Eggert  <[e-mail]>

	Work around problems found when POSIXLY_CORRECT=1 is set.
	None of this seems to have anything to do with POSIX, really,
	but it's how Perl getopt works.

	"permute", too.
	* doc/autoconf.texi (Invoking autom4te):

2002-09-28  Akim Demaille  <[e-mail]>

	* tests/torture.at (Configuring subdirectories): Be robust to
	users who use config.site to require for a cache: in this case,
	the two last configure runs, using two different sets of
	arguments, trigger a legitimate error.

2002-09-28  Akim Demaille  <[e-mail]>

	* tests/m4sh.at (Functions Support, Functions and return Support):
	New.

2002-09-28  Akim Demaille  <[e-mail]>
