Do not call `_exit()', simply modify `$?'.
(xsystem): Reset $! before running system, and check it afterward.
* tests/tools.at (autoupdating AC_PREREQ): Expect exit status
63 for version mismatches.
Emacs' danger whitespace.el behavior (smashing "useless" spaces in
the middle of a line).
* lib/m4sugar/m4sugar.m4: Likewise.
Remove useless spaces in comments.
Remove `#include <stdlib.h>' from the list; we should never
make confdefs.h include <stdlib.h> or <cstdlib>, because the
resulting namespace pollution would cause other tests to fail.
Configure scripts run with some older versions of g++ and HP's
aCC would fail due to such an #include. Problems reported by
Matthew Mueller in <http://bugs.debian.org/120704> and by
Keith Bostic in
<http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
In the test, use the test declaration before including <stdlib.h>,
as that's closer to how it'll be used.
in testsuite.dir/NNN/testsuite.log, and append them to
testsuite.log instead of re-running the test verbosely.
Adapt documentation. Update NEWS to signal possible bad
interactions between -x and experr.
memcmp be declared before being tested.
Reported by Sander Niemeijer.
(AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
* doc/autoconf.texi (Default Includes): Document
AC_INCLUDES_DEFAULT.
* bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
them uniform, and more robust to Perl special characters.
Reported by Martin Mokrej.
longer updates aclocal.m4 if useless, (ii) if a file m4_included
by aclocal.m4 is changed it might require the importing of another
m4 extension file, i.e., aclocal must be run.
* bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
(&parse_args): Use --force with aclocal if required and supported.
(&autoreconf_current_directory): Use &run_aclocal.
* lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
* bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
argument instead of a file name, so that the request file remains
open during the whole autom4te run.
($icache_file): New.
(&freeze): Lock the $icache_file.
seperator with m4_append_uniq(). It doesn't work.
(AT_CLEANUP): Add `;' to end of at_help_all.
(AT_INIT): Allow --keywords to be specified more than once. When
grepping $at_help_all for keywords, use the field and keyword
seperators to ensure a complete keyword match. Alter at_prev handling
to support the new --keywords behavior.
I also made some of the individual entries on one line, for brevity
and to make it easier for me to sort my dir-example file in the
Texinfo distribution :).
