554 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
556 Fix some write failure cases in Autotest.
557 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully
558 upon write failures for --help, --version, --list.
559 Guard against write failures for intermediate created scripts.
560 <at_func_create_debugging_script>: Do not make the debugging
561 script executable if it is not complete.
563 2007-12-12 Eric Blake <ebb9@byu.net>
565 Fix thinko in earlier patch - m4_join isn't defined yet.
566 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
567 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
568 (m4_require): Use m4_do, not m4_join.
570 Fix some whitespace tests on cygwin.
571 * tests/tools.at (autom4te and whitespace in file names): Restore
572 font-lock. Create $TMPDIR before it might be used.
574 Fix spurious testsuite failure with M4 1.4.11.
575 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
578 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
579 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
580 (m4_require): Avoid extra macro calls.
582 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
584 * tests/torture.at (srcdir): Fix quoting.
586 Do not pass top_srcdir to configure scripts in testsuite.
587 * tests/autotest.at (srcdir propagation): Copy install-sh to
589 (my only test): Drop setting of `top_srcdir'.
590 * tests/base.at (Input/Output): Likewise.
591 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
592 config.guess, and config.sub to test source tree.
593 Drop AC_CONFIG_AUX_DIR setting.
594 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
595 * tests/torture.at (Substitute a 2000-byte string): Drop
596 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
597 (Substitute a newline, datarootdir workaround): Likewise.
598 (Define a newline): Adjust for linenumber changes in configure.ac.
599 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
601 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
602 if `pwd` contains whitespace.
604 Quote $abs_top_srcdir in tests.
605 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
606 * tests/tools.at (Syntax of the shell scripts): Likewise.
608 * tests/m4sh.at (LINENO): Quote $0.
610 Fix testsuite program wrapper for whitespace in `pwd`.
611 The problem here is that the usual mantra is that command
612 variables can contain arguments, thus we cannot just escape
613 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
614 $top_builddir/tests directory early in $PATH, so that the
615 wrappers are found by their plain name.
616 * tests/wrapper.as: Put $testdir early in $PATH.
617 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
619 Proper config.status --file/--header and $srcdir escaping.
620 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
621 characters in $ac_file_inputs.
622 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
624 * tests/torture.at (datarootdir workaround): Adjust.
625 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
627 Fix Autotest for whitespace in `pwd`.
628 * lib/autotest/general.m4 (AT_INIT)
629 <at_func_create_debugging_script, Driver Loop>:
631 * tests/autotest.at (whitespace in absolute testdir): New test.
633 * lib/autom4te.in: Quote @datadir@.
635 Proper file name escaping in Autoconf programs and Perl modules.
636 This includes escaping of characters special to the shell
637 as well as special to Perl, e.g., leading `<' or `>'.
638 For example, when $file starts with `>', `open ">$file"'
639 wrongly tries to append to a different file.
640 * bin/autoconf.as: Fix quoting for autom4te options.
641 * lib/Autom4te/General.pm (shell_quote): New function, taken
642 from coreutils, written by Jim Meyering.
644 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
646 * bin/autoreconf.in (parse_args): Likewise.
647 * bin/autoscan.in (main): Likewise.
648 * bin/autoupdate.in (main): Likewise.
649 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
650 * bin/ifnames.in: Likewise, XFile usage fixes.
651 * tests/tools.at (autom4te and whitespace in file names): Extend
652 test. Test twice, with special characters allowed on w32, and the
653 rest. Test leading and trailing whitespace, for `open_quote'.
654 (autotools and whitespace in file names): New, analogous test.
655 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
656 by Russ Allbery and Eric Blake.
659 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
660 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
661 * lib/Autom4te/FileUtils.pm (open_quote): New function.
662 (update_file, contents): Use it.
664 * Makefile.am (autom4te-update): Rewrite for git.
666 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
668 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
671 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
672 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
674 2007-12-04 Eric Blake <ebb9@byu.net>
676 Manually resync with gnulib, since 'make cvs-update' no longer works.
677 * build-aux/config.guess: New upstream version.
678 * build-aux/config.sub: Likewise.
680 When using older automake, don't downgrade build-aux/texinfo.tex.
681 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
682 * doc/Makefile.am (TEXINFO_TEX): Add.
684 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
686 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
687 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
688 #undef as this runs afoul of our new way of creating config.h.
689 Problem reported by Jim Meyering in
690 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

694 Fix autom4te for unusual characters in input file names.
695 * bin/autom4te.in (files_to_options): Quote active characters
697 * tests/tools.at (autom4te and white space in file names):
700 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
701 Document that Tru64 awk always splits $0.
703 2007-11-24 Stepan Kasal <kasal@ucw.cz>
705 * lib/autotest/general.m4 (AT_INIT): Do not extract the
706 `#AT_STOP_...' line at the end of each test.
708 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
710 * lib/autotest/general.m4 (AT_INIT): For awk line number
711 extraction script, ensure `$at_group' has a defined value
712 even for the empty set, and properly quote its usage inside
715 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
717 * doc/autoconf.texi (Shell Functions): New chapter. Document
718 IRIX sh $0 issue in functions, move content from ...
719 (Portable Shell): ... here.
720 (Shell Script Compiler): Note that shell functions are not
721 totally unportable any more.
723 2007-11-22 Stepan Kasal <kasal@ucw.cz>
724 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
726 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
727 extracting the line numbers of the last needed test.
729 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
731 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
734 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
736 Fix IRIX testsuite debugging failures: $0 in functions.
737 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
738 Do not use $0 inside a function, as IRIX sh will set that to the
739 function name rather than the script invocation name.
741 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
742 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
744 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
745 to extract test scripts.
746 (AT_INIT): Extract and cache test script line numbers.
748 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
750 * lib/autotest/general.m4: Revert 2007-11-15 patch and
751 subsequent fixups; the awk -> here-document conversion trashes
752 performance too much with AIX sh.
754 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
756 * tests/local.at: Do not test m4, perl with AT_TESTED.
758 Diagnose and guard against write errors dealing with config.status.
759 The general idea is this: all write failures from `configure'
760 writing `config.status' are indicated by $ac_write_error, which
761 is only checked at the end. This is safe because config.status
762 code is not executed before the file is complete. Other write
763 failures, be they inside config.status, or in sub shell/awk
764 scripts spawned from configure or config.status, typically need
765 earlier checking, as their results are used right afterwards.
766 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
767 before writing config.status, check afterwards.
768 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
769 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
770 Set `ac_write_error' for write failures to config.status. Barf
771 upon write failures to temporary files.
772 Adjust note about closing and reopening the here-document.
773 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
774 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
775 reopening the here-document.
776 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
777 Ensure `ac_write_error' does not escape into config.status.
778 Also, add a couple of code paths not yet exercised in the test
779 suite: a config file with input from stdin, and a config header
781 Suggestion for catching write errors by Bruno Haible.
783 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
785 Avoid error with Tru64 awk and testsuite lines with many words.
786 * lib/autotest/general.m4 (AT_INIT): In the awk script that
787 reads the testsuite, set the field separator to an unusual value,
788 in order to not run over the limit of 199 fields. Tru64 4.0D awk
789 even splits the input if $i, i>0, was never accessed in the script.
791 Revert 2007-10-17 change.
792 * TODO: Multiline args in config files and headers mean something
793 different and are not fixed, see
794 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>

799 2007-11-16 Stepan Kasal <kasal@ucw.cz>
801 AC_*_TOOL does not canonicalize the prefix
802 * doc/autoconf.texi (Generic Programs): Do not say that
803 the *_TOOL macros canonicalize, they simply use the `host_alias'.

807 Diagnose write errors in config.status instantiations.
808 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

811 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
812 Extend test to also check for some write error failures, using...
813 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
814 Report by Bruno Haible.
817 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
819 (_AT_CHECK): Use less indentation, to save space.
821 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
823 Add witness macro for @top_build_prefix@ substitution.
824 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
825 (_AC_OUTPUT_FILE): Mention it here.
827 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
828 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
830 * lib/autotest/general.m4 (at_func_test): Remove.
831 (AT_INIT): Pre-extract test groups into separate files.
832 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
833 Remove at-test-source files together with the $at_group_dir.
834 * tests/autotest.at (Long test source lines): New test.
836 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
838 Shell functions and variables may share a namespace.
839 * doc/autoconf.texi (Portable Shell): Mention Solaris sh

847 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
849 * lib/autoconf/status.m4: Fix a couple of comment typos.
851 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
853 2007-11-13 Jim Meyering <meyering@redhat.com>
855 Clean up the rule to create "expr".
856 * tests/Makefile.am (expr): Don't redirect directly to target.
857 Redirect just once, not for each echo statement.
858 Use $@, not literal "expr".
860 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
862 Don't worry about preprocessor when testing long long.
863 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
864 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
865 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
866 These no longer check for preprocessor flaws.
867 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
868 Do not check for preprocessor flaws.
870 2007-11-13 Jim Meyering <meyering@redhat.com>
872 Adapt dependencies, now that a version change doesn't modify configure.ac
873 * GNUmakefile: Remove "make clean" kludge.
874 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
876 Don't redirect directly to target.
877 Use $@, not literal "version.m4".
879 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

882 ":;{" shorthand as in previous patch.
884 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
886 * doc/autoconf.texi (Limitations of Builtins): Document problem
887 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
889 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
891 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
893 2007-11-12 Jim Meyering <meyering@redhat.com>
895 Add more non-srcdir build support.
896 * GNUmakefile (dummy): Split a long line.
897 Add -v option to autoreconf invocation.
899 Remove the autoreconf-provided INSTALL, so that we regenerate it.
900 * GNUmakefile (dummy): Remove INSTALL.
902 Remove racy commands to build scripts in bin/ and tests/.
903 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
904 are guaranteed to be built, remove the rules that tried to build
905 them. Before, with a parallel build, these rules could lead to
906 two processes writing tests/wrapper.in concurrently.
908 Build in man/ only *after* building in bin/ and tests/.
909 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
910 in both bin/ and tests/.
912 Accommodate non-srcdir build-from-checkout.
913 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
914 Use git's --git-dir=$srcdir/.git option.
915 Add quotes, in case tarball_version_file contains shell meta-characters.
916 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
917 * configure.ac: Pass "." to git-version-gen.
919 Avoid spurious test failures due to version skew.
920 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

947 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
949 Ignore configure --help* errors due to LINENO-impaired shells.
950 * tests/torture.at (Configuring subdirectories, Deep Package):
951 In the --help* tests in read-only trees, make `.' temporarily
952 writable again for the `stderr' file, and ignore errors due to
953 the attempt to write configure.lineno.
954 Report by Patrick Welche.
956 2007-11-10 Jim Meyering <meyering@redhat.com>
958 Generate package.m4 in build-dir, not srcdir.
959 * tests/Makefile.am (package.m4): Adjust target.
960 Don't redirect directly to $@.
961 (CLEANFILES): Add package.m4.
962 ($(TESTSUITE)): Depend on just-built package.m4, not the one
964 When running $(AUTOTEST), search "." before searching $(srcdir).
966 Avoid a race condition that would make parallel "distclean" fail.
967 * tests/Makefile.am (distclean-generic): Replace the default,
968 automake-provided rule with an identical one, but with an additional
969 dependency on distclean-local. Simply adding the dependency would
970 cause automake not to emit the rule at all.
971 * BUGS: Building with -jN works, now.
973 Distribute git-version-gen.
974 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
975 since GNUmakefile is distributed, and requires it for dist* rules.
977 Remove two more generated files from version control.
978 * INSTALL: Remove generated file.
979 * lib/autoscan/autoscan.list: Remove generated file.
981 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
983 * GNUmakefile (PATH): Remove stray apostrophes; they become
984 part of PATH, which isn't wanted here.
986 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
988 New config files output variable `top_build_prefix'.

991 * doc/autoconf.texi (Preset Output Variables): Document it.
993 Report by Bob Friesenhahn.
995 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
996 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
997 function, to parametrize arithmetic with expr vs. the shell.
998 Use it where possible.
999 Suggestion by Benoit Sigoure.
1001 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1003 Adjust the documentation of autotest WRT atlocal.
1004 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1005 when using Automake, to write a rule to produce atlocal, since it's
1006 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1007 distributed, not atconfig.in.
1009 2007-11-04 Eric Blake <ebb9@byu.net>
1011 Update list information.
1012 * README: Mention new autoconf-commit list.

1027 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1028 * build-aux/git-version-gen: This syncs from coreutils.
1030 Adjust the build procedure so "make check" works reliably.
1031 * README-hacking: Include an extra step between "make" and
1032 "make check" to ensure that the latter passes.
1034 Use just-built tools, when possible.
1035 * GNUmakefile (PATH): Set and export here, ...
1036 (dummy): ... rather than here.

1108 Make inter-release --version output more useful.
1110 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1111 which indicates that it is built using the 19th change set
1112 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1113 is a prefix of the commit SHA1.
1114 * build-aux/git-version-gen: New file.

1121 not configure.ac, now that the version number changes automatically.
1123 Ensure that $(VERSION) is up to date for dist-related targets.
1124 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1125 git-version-gen doesn't match $(VERSION), but only for dist targets.

1198 Fix config header generation with AIX awk.
1199 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk

2560 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
2562 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
2563 input from /dev/null in awk test, so even Solaris /usr/bin/awk
2564 will not wait for input with a script containing only a BEGIN

2598 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2600 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
2601 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2602 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2603 substitution will still be done by the special code.
2604 Report by Jim Meyering.
2606 * doc/autoconf.texi (File System Conventions): Mention that
2607 $PATH_SEPARATOR is for the build system only.

2616 carriage return for $AWK, needed for BSD awk.
2617 * tests/torture.at (Substitute and define special characters):
2618 Test all 8 bit non-NUL characters.
2619 Report against Automake by Patrick Welche.
2621 2007-01-15 Stepan Kasal <kasal@ucw.cz>
2623 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
2625 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2627 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2628 early on the reader side, drop stderr of the input to avoid
2629 `broken pipe' error output; this may happen even with shell
2630 builtin `echo' of some bash versions. Reports by Ian Macdonald
2631 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
2633 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2635 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
2636 separate items of `ac_user_opts', to avoid long lines.
2637 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
2639 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2643 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
2645 Fix some wording problems noted by Paolo Bonzini in:
2646 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
2647 * doc/autoconf.texi (Signed Overflow Examples): Give more
2648 discussion about the allow_superuser_privileges example,
2649 and change it a bit to make things clearer.
2650 (Optimization and Wraparound): Clarify whether the compiler
2651 will generate an infinite loop for the example derived from
2652 Autoconf's mktime test.
2653 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2654 Also, clarify unsigned multiplication overflow.
2656 2007-01-04 Eric Blake <ebb9@byu.net>
2658 * bin/Makefile.am (RELEASE_YEAR): New macro.
2659 (edit): Use it to supply correct copyright year to scripts.
2660 * bin/autoconf.as (version): Use it.
2661 * bin/autoheader.in ($version): Likewise.
2662 * bin/autom4te.in ($version): Likewise.
2663 * bin/autoreconf.in ($version): Likewise.
2664 * bin/autoscan.in ($version): Likewise.
2665 * bin/autoupdate.in ($version): Likewise.
2666 * bin/ifnames.in ($version): Likewise.
2668 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
2670 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2671 feedback. The most important changes document what happens when
2672 you convert an out-of-range value to a signed integer type, and
2673 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2676 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2677 rewrite, taking notions from the recent discussion on the gcc and
2678 autoconf mailing lists; please see
2679 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2680 and follow the many links.
2681 (Integer Overflow Basics, Signed Overflow Examples):
2682 (Optimization and Wraparound, Signed Overflow Advice):
2683 (Signed Integer Division): New sections.
2685 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2687 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2688 preprocessor macro arguments in traced name.
2689 * doc/autoconf.texi (Defining symbols): Document longstanding
2690 support for AC_DEFINE-ing macros with arguments, and document
2691 behavior when the same variable has multiple AC_DEFINEs.
2692 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2693 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2694 macros directly, giving much shorter and simpler code.
2696 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2698 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2699 space before "$ac_configure_args" to prevent a 'config.status
2700 --recheck' failure if ac_configure_args doesn't contain a leading
2701 space. This works around a problem with the XEmacs configure.ac,
2702 which uses the (undocumented) ac_configure_args variable
2703 inconsistently with Autoconf.
2705 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2707 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2708 Include <limits.h>, and use its INT_MAX to rewrite the
2709 j loop so that it does not overflow 'int'. Problem reported by
2711 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2712 Play it safe by shifting left by 1 rather than multiplying by 2,
2713 as GCC is less likely to optimize this away when the value
2714 is signed (when it assumes overflow leads to undefined behavior).
2715 Also, don't assume time_t uses two's complement.
2717 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2719 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2720 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2721 dumps core on it. Report by Tim Rice.
2723 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2725 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
2726 --disable-option-checking to --help output even when
2727 AC_PRESERVE_HELP_ORDER is not used.
2728 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
2729 --with argument, rather than argument with [-.] replaced by
2731 * NEWS: Fix typo in previous change; the news was in the
2734 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2736 * NEWS: Warnings are now generated by default for unknown
2737 --enable-* and --with-* options.
2738 * doc/autoconf.texi (Option Checking): Renamed from
2739 (Configure Option Checking). Tighten up the wording a bit.
2740 (External Software, Package Options): Cross-reference to Option
2741 Checking, and use this to shorten our section.
2742 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2743 "$x" to test "x$foo" != x.
2744 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
2745 Don't warn if $enable_option_checking is "no".
2746 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
2747 ac_unrecognized_opts to the empty string.
2748 Don't echo the unrecognized opts, as this might mishandle
2749 backslashes or leading -.
2750 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
2751 usage next to the other --disable-FEATURE options in the
2754 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2756 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
2757 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
2758 Print warning for unrecognized --with and --enable options
2759 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2760 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2761 Disable option checking when subdirs are configured.
2762 (AC_OUTPUT): If warnings are enabled, print warning about
2763 unrecognized --with and --enable options at the end of
2764 the configure output (as well as at the beginning).
2765 * doc/autoconf.texi (Option Checking): New node.
2766 Document new option warning functionality.
2768 2006-12-16 Eric Blake <ebb9@byu.net>
2770 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
2771 * NEWS: Start news for current version.
2773 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
2775 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2776 Define HAVE_GETMNTENT to 1, not to the empty string.
2777 Problem originally reported by Jochen Friedrich in
2778 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
2780 This change prompted by a problem report by Andrey Simonenko in
2781 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
2782 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
2783 object-like macros only, in the traditional portable character
2785 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
2786 Warn about attempts to define things that are not identifiers.
2787 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
2788 awful hack that AC_DEFINEd macro names containing parentheses.
2790 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
2792 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
2793 too drastic, even if Texinfo in theory requires it for info mode.
2795 (config.status Invocation): Renamed back from Recreating a
2797 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
2798 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
2800 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2802 * NEWS: Version 2.61a.
2804 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2805 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2807 * NEWS: Document changes with echo and printf, and the lack
2808 of limits on the total size of multi-line values of substituted
2809 variables, and the AC_FUNC_FSEEKO fix.
2811 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
2813 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
2814 Writing configure.ac.
2815 (Autoconf Input Layout): Renamed from configure.ac Layout.
2816 (Recreating a Configuration): Renamed from config.status Invocation.
2817 (Obsolete Recreation): Renamed from Obsolete config.status Use.
2818 (acconfig Header): Renamed from acconfig.h.
2819 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
2820 (Writing Testsuites): Renamed from Writing testsuite.at.
2821 (Autom4te Cache): Renamed from autom4te.cache.
2823 * BUGS: Remove mention of VPATH problem, since it's now documented
2824 not to be a bug in the Autoconf build procedure itself, but rather
2825 a problem with the proprietary `make' programs.
2827 * doc/autoconf.texi (Build Directories): Add a cross reference
2830 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
2831 * doc/standards.texi: Sync from gnulib.
2833 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
2834 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
2835 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
2836 generated automatically.
2838 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
2840 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
2841 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
2842 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
2844 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2846 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
2847 `CEOF$ac_eof' special marker, the awk script cannot contain a
2848 line matching `^CEOF', so this is not needed any more.
2849 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
2850 special marker in the test.
2852 2006-12-06 Stepan Kasal <kasal@ucw.cz>
2854 * tests/tools.at (autom4te preselections): Use `find -newer';
2855 remove one of the sleeps.
2857 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
2858 more readable, using ...
2859 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
2861 * doc/autoconf.texi (autoheader Invocation): Do not double-
2862 quote the parameter of `AH_BOTTOM' in the example.
2864 2006-12-05 Stepan Kasal <kasal@ucw.cz>
2866 * doc/autoconf.texi (Configuration Headers): Remove the
2867 example with multiple input files.
2868 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
2869 multiple input files.
2871 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2873 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
2874 creating the awk substitution script, handle one input line at a
2875 time, so that the maximum length of a substituted (multi-line)
2876 value is not limited by the size of the sed pattern space.
2877 The trade-off is a slightly repetitive sed script.
2878 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
2879 can only have up to 7 characters, due to Solaris 10 /bin/sed.
2880 * tests/torture.at (Substitute a 2000-byte string): Increase the
2881 test with several long lines, they should not be caught by sed
2884 * tests/tools.at (autom4te preselections): New test, to flag
2885 entries missing from autom4te.cfg.
2886 Report by David Byron <dbyron@hheld.com>.
2888 * tests/torture.at (Substitute a 2000-byte string): Actually use
2889 AC_PROG_AWK, so the last change works as intended.
2890 (Substitute and define special characters): Likewise.
2891 (Substitute a newline): Likewise.
2893 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
2894 instead of `awk' consistently.
2895 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
2896 * tests/torture.at (Torturing config.status): Test both the
2897 result of AC_PROG_AWK and plain awk.
2898 (Substitute a 2000-byte string): Likewise.
2899 (Substitute and define special characters): Likewise.
2900 (Substitute a newline): Likewise.
2902 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
2904 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
2905 can be assigned to a function pointer. Problem reported by
2906 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
2907 part of a patch by Ralf Wildenhues in that same bug report.
2909 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
2911 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
2912 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
2914 2006-12-01 Eric Blake <ebb9@byu.net>
2916 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
2917 cross-compiling from cygwin to mingw.
2918 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
2919 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
2920 to lib/autoconf/c.m4.
2922 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2924 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
2925 string for more reliable failure. Wrap the entire test that
2926 causes the broken Solaris printf to dump core, in a subshell,
2927 so the segmentation fault message is reliably suppressed.
2928 Fix shell expansion errors by using /usr/ucb/echo always;
2929 avoid an error on systems without it by another subshell.
2930 Avoid m4 expansion of `$1'. Set the zeroth argument of the
2931 subshell-$as_echo to `as_echo', for better error message.
2933 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2935 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
2936 `BASH_SOURCE' contain a newline, set them to empty, as they may
2939 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
2941 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
2942 years and is too hard to maintain now. The last straw was
2943 reported by Jerker Baeck in
2944 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
2945 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
2946 * doc/autoconf.texi (Particular Functions): Move
2947 AC_FUNC_SETVBUF_REVERSED from here...
2948 (Obsolete Macros): ... to here. Say that it does nothing now.
2949 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
2950 Turn into (almost) a no-op.
2952 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
2954 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
2955 These macros are obsolescent and new applications shouldn't need them.

2963 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
2965 * doc/autoconf.texi (Setting Output Variables): Mention that
2966 @VAR1@VAR2 has unspecified behavior. Problem reported by
2968 * NEWS: Mention this.
2970 * Makefile.am: Put only a single '#' into the copyright notice,
2971 so that it's also present in the output file. Standardize wording
2972 in makefile copyright notices to match GNU coding standards.
2973 * bin/Makefile.am: Likewise.

2986 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2988 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
2989 in the sed script that mangles the awk script: delete up to the
2990 first exclamation mark only.
2991 * tests/torture.at (Substitute and define special characters):
2994 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2996 Rewrite config files generation: avoid quadratic growth in
2997 the number of substituted variables by using awk instead of sed
2998 for the bulk of the substitutions.
2999 * NEWS: Mention this.
3000 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3001 forbidden in the output (and thus input) file.
3002 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3003 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3004 generate just one large awk script for substitutions,
3005 eliminating much of the earlier complexity, while adding some
3006 new complexity. Only expand the substitution templates at
3007 configure time, for smaller configure script size. If
3008 _AC_SUBST_FILES are used, test 'awk' for working getline support
3009 at config.status time. If absent, interpolate through the
3010 shell. The awk script was written with much help
3011 from Paolo Bonzini and Paul Eggert.
3012 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3013 (_AC_SED_FRAG_NUM): Likewise.
3014 (_AC_SUBST_CMDS): Renamed from...
3015 (_AC_SED_CMDS): ...this.
3016 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3017 * tests/torture.at (Substitute a 2000-byte string): Also
3018 substitute a line with 1000 words, and a variable with several
3020 (Substitute and define special characters): Test awk special
3021 characters, and put substitution input strings `@foo@' in the
3022 output, to test that no recursion happens; test several other
3023 combinations from Paolo Bonzini.
3025 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3027 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3028 that replaced echo with AS_ECHO where this wasn't necessary.
3029 Problem reportd by Ralf Wildenhues.
3030 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3031 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3032 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3034 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3036 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3038 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3040 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3041 that traditional Awk lacks 3-arg "split". It has it.
3042 Mention that FS must be a single character, and a few other
3043 99-byte limits of traditional Awk.
3044 Mention that if (i in a) doesn't work with traditional Awk.
3046 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3048 * tests/autotest.at (BSx641-newline in command):
3049 (BS-BS-newline in command, BSx640-newline in command):
3050 (Newline-CODE-BS-newline in command):
3051 (Single-quote-BS-newline in command):
3052 (Single-quote-newline-BS-newline in command):
3053 Use printf '%s\n' instead of echo, for portability to hosts
3054 where echo interprets backslashes. This will break on hosts
3055 that lack printf, but for now let's assume all such hosts
3056 are dead (if not, we should get reports of test failures).
3058 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3060 'echo' has some portability problems, when given a first argument
3061 with a leading '-', or when given any argument containing '\'.
3062 Avoid using 'echo' in these cases.
3063 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

3087 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3088 * bin/autoconf.as: Redo verbose flag implementation, as the old
3089 scheme wouldn't work with AS_ECHO.
3090 * lib/autotest/general.m4 (AT_INIT): Likewise.
3091 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3092 Don't use ECHO_T, since ECHO_N is now reliable.
3093 * lib/autotest/general.m4 (AT_INIT): Likewise.
3094 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3095 rather than using a here-document to put the script into a file.
3096 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3098 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3099 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3100 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3101 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3102 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3103 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3104 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3105 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3106 operand, as AS_ECHO requires. Avoid double file name expansion.
3107 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3108 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3109 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3110 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3111 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3112 Double-quote strings that would otherwise contain M4 comments.
3113 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3115 * configure.ac (AC_INIT): Bump to 2.61a.
3118 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3122 * configure.ac (AC_INIT): Bump to 2.61.
3125 * tests/autotest.at (Macro with backslash in a test title):
3126 Comment out for now, as this tests neither fails nor passes
3127 reliably. Problem reported by Ralf Wildenhues.
3129 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3131 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3132 in previous change, which caused test failures.

3206 benefit of platforms like Solaris+GCC where it is common to have a
3207 non-working g++ installation.

3211 and Paul Eggert <eggert@cs.ucla.edu>
3213 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
3214 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
3217 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3219 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3220 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3221 Imported from a similar patch to gnulib by Bruno Haible.
3223 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

3242 and Stepan Kasal <kasal@ucw.cz>
3244 Handle special characters in test case titles correctly.
3245 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
3247 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3248 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3249 argument. Extend to check titles printed by ./micro-suite and
3250 ./micro-suite -l and the title in micro-suite.log.
3251 (Backquote in a test title,
3252 Single-quote in a test title,
3253 Double-quote in a test title): Don't expect failure anymore.
3254 (Backslash in a test title): Put a non-whitespace character after the
3255 backslash so that Bourne shells might actually see it as an escape
3257 (Brackets in a test title,
3258 Pound in a test title,
3259 Comma in a test title,
3260 Quoted Macro in a test title,
3261 Macro in a test title,

3264 Macro with double-quote in a test title,
3265 Macro with backslash in a test title): New tests expected to fail.
3266 * tests/torture.at (#define header templates): M4-quote this title in
3267 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3268 The visible effect was a stray [] in the testsuite output.
3270 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3272 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3273 `trap ... 0' inside a function, for AIX sh.
3275 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3277 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3278 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3279 5363) simply issues a warning when dividing by zero at compile
3280 time. Problem reported by Elias Pipping.
3282 2006-10-26 Eric Blake <ebb9@byu.net>
3285 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3286 show effect on macros that expand with commas.

3311 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3313 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3314 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3315 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3316 reported by Nelson H. F. Beebe for Coreutils 6.4.
3318 * tests/tools.at (autoconf --trace: user macros): Remove test
3319 for tracing multiline macros, since m4 1.4.7a uses a different
3320 way to number lines. Problem reported by Ralf Wildenhues.
3322 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3324 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3325 /dev/null since the heuristics for interactive behaviour was

3350 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3351 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

3382 looking for special shell characters.
3383 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
3384 macro defined by AS_VAR_PUSHDEF before passing it as a

3396 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3398 (Imported from Automake.)
3399 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3400 which incorrectly sets the mode of an existing destination
3401 directory. In some cases the unpatched install-sh could do the
3402 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3403 system. We hope this is rare in practice, but it's clearly worth
3404 fixing. Problem reported by Alex Unleashed in
3405 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3406 Also, don't bother to check for -m bugs unless we're using -m;
3407 suggested by Stepan Kasal.

3440 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
3441 (\code): must use new \...Char values, since now ` is active.

3451 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
3453 2006-10-13 Stepan Kasal <kasal@ucw.cz>
3455 * doc/autoconf.texi (Autoheader Macros): Warn that the text
3456 added to the template can get mangled.
3458 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3460 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3461 include the default headers, and redefine obstack_chunk_alloc
3462 and obstack_chunk_free. Fixes false failure with glibc.

3481 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
3483 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
3484 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3485 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3486 Use a better substitute, by inspecting the output of "ls"
3487 rather than just using ":".
3488 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3489 rather than AS_EXECUTABLE_P, since we needn't worry about
3490 non-regular files here.
3492 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3493 due to configuration hassles with this. See Tonya Underwood's report
3494 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

3517 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3518 comment about ac_cpp_err; it was incorrect, and anyway
3519 ac_cpp_err is being removed below.
3520 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3521 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3522 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3524 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3525 with werror_flag and conftest.err and so forth. This is more
3526 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3527 and anyway the user shouldn't normally want to see this gorp logged.
3528 Problem reported by Ralf Wildenhues.
3529 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3530 empty, not 'no', since the rest of the code uses 'test -z'.

3534 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):

3538 Problem reported by mwoehlke in
3539 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3541 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3542 than creating a file to use with test -x; this is much faster.

3556 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

3564 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
3565 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just

3582 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
3583 can apply to constants too, and that it checks for macro defns.
3584 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

3586 values. Problem reported by Ralf Wildenhues.

3676 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check

3680 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
3681 7.1.4 /usr/bin/posix/sh described by Tim Rice in

3799 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
3800 didn't work if some values were cached but not others. Test for
3801 broken lex libraries like native ia64-hp-hpux11.22; see
3802 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
3803 work around the problem by preferring an empty LEXLIB to -lfl or

3926 longer supported by Sun.
3928 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
3930 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
3931 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
3932 -Wundef -Werror". Problem reported by David Fang in
3933 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

3955 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
3956 problems with arg script text that doesn't end in newline, and
3957 with '-e a...'. Problems reported by Ralf Wildenhues.
3959 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
3961 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
3962 check for libXt by a check for libX11.

3973 settings. Report by Bruno Haible.
3975 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
3977 Fix test suite failures reported by Pierre in
3978 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.

3993 less skeptical about "volatile", after discussion with
3994 Bruno Haible on bug-gnulib.

3996 leading white space from text. From Bruno Haible.
3998 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4000 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4001 compiler complains about it, even if things works after the
4002 complaint. Problem reported by Peter O'Gorman.
4004 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
4005 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
4006 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
4008 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4010 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
4011 after -R regardless of host. Patrick Welche reports that this

4022 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4023 under AC_C_VOLATILE.
4024 (Volatile Objects): Be a little less skeptical about what
4025 "volatile" means. Derived from thoughts by Ben Pfaff in
4026 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4028 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4030 * doc/autoconf.texi: Fix some typos.
4032 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4034 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4035 more globally, since the 2006-06-30 patch didn't suffice. Problem
4036 reported by Keith Marshall. Also, don't bother with builddir2,
4037 since it shouldn't be needed any more.
4039 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4041 * doc/autoconf.texi (Generic compiler characteristics):
4042 Document AC_COMPUTE_INT. Fix wrong statements on Default

4056 * NEWS: Document previous change.
4058 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4060 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4061 Require that long long int be at least 64 bits wide. C99 requires
4062 this and enough programs depend on it so we should check for it.
4063 Bruno Haible reports in
4064 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4065 that long long int is 32 bits wide with some nonstandard compilers.
4066 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4068 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4070 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4071 to a nonexistent file, so that we don't have to worry about
4072 a local site configuration that doesn't use /usr/local.
4073 Problem reported by Keith Marshall in
4074 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4076 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4078 * doc/autoconf.texi: Be more consistent about using @acronym with
4079 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4080 quite right (it talked about "OSF/Tru64", even though the
4081 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4082 and it even mentioned "OSF 4"!) and at this point there's little
4083 reason to talk about OSF any more, since it died in 1994.
4084 (Specific Compiler Characteristics): Simplify example of
4085 negative-size array.
4086 (File Descriptors): Reorder to make the text flow better.
4087 Remove joke about "appreciate the various levels"; I didn't get it.
4088 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4089 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4090 (File Descriptors, Limitations of Usual Tools):
4091 Tone down the advice against renaming or removing open files.
4092 (Limitations of Usual Tools): Add a new section, on 'rm'.
4094 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4096 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4097 -lXt in LIBS, idea from Karsten Hopp; this was due since
4100 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4101 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4102 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4103 (which belong to Xt, not X itself). See Debian bug 327655.
4105 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4107 * configure.ac (AC_INIT): Bump to 2.60a.

4114 * configure.ac, NEWS: Update.
4116 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4118 * config/texinfo.tex: Sync from upstream.

4127 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4129 * doc/autoconf.texi (Changed Directory Variables): New node,
4130 to document the whole `datarootdir' business a bit better.
4132 * tests/torture.at (datarootdir workaround): Extend test.
4133 Prompted by report by Alexandre Julliard.
4135 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4137 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4138 when using default mode of IBM C 6 for AIX. Problem and two-line
4139 fix reported by Larry Jones.
4141 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4143 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4144 about literal '${datarootdir}' if a definition is found in the
4147 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4149 * NEWS: Use "M4" rather than "m4" when appropriate.
4150 Problem reported by Eric Blake.
4151 * doc/autoconf.texi: Likewise.
4152 Use @acronym around BSD, GCC, and GNU when appropriate.
4153 (Why GNU M4): Renamed from "Why GNU m4".
4154 (Redefined M4 Macros): Mention that Posix
4155 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4156 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4159 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4161 * bin/autom4te.in (handle_output): Do not forbid the empty
4163 * tests/tools.at (autoconf: the empty token): New test.
4165 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4167 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4168 calls, so that we do not care whether they are LIFO or FIFO;
4169 in the m4_wrap, do not check which diversion is the topmost
4170 one, just check that the stack is balanced at the end.
4171 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4172 base diversion forever--pop the previous diversion before
4173 opening the new one; consequently, remove the m4_wrap call.
4174 * lib/autotest/general.m4 (AT_INIT): Likewise.
4175 * tests/m4sugar.at: Do not use
4176 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

4179 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4181 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4182 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4183 Rework example of m4wrap token-pasting trouble so that it doesn't
4184 care whether it's LIFO or FIFO.
4185 Fix some "contrary to"s that are awkward in English.
4187 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4189 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4190 to `yes' instead of `int$1_t' if the type is found, for more
4191 consistent configure output (where $1 is the number of bits).
4192 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4193 Suggested by Bruno Haible.
4195 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4196 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4197 with system headers. Report by Bruno Haible.
4199 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4201 * config/config.guess, config/config.sub: Sync from upstream.
4203 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4204 in order to avoid picking up an older installed frozen m4sh.m4f.
4205 Besides an outdated shell startup, this could have been created
4206 by an earlier M4 version with incompatible frozen file format.
4208 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4210 * README: Recommend m4 1.4.4 instead of 1.4.3..
4211 * doc/autoconf.texi: Likewise.
4212 (Special Chars in Names): Say that $(.FOO) is portable, as
4213 suggested by Stepan Kasal.
4214 (Installation Directory Variables, Build Directories):
4215 (Automatic Remaking, Subdirectories, Fortran Compiler):
4216 (Making testsuite Scripts, Defining Directories):
4217 Quote variable usages better.
4218 (Making testsuite Scripts): Add clean-local rule to makefile
4219 snippet, by Eric Blake.
4220 (Installation Directory Variables): Fix table item font.
4221 Reword slightly to clarify. Generalize advice about
4222 not using special characters to include all file-related
4223 vars, not just VPATH.
4224 (Special Chars in Variables): Warn about special characters in
4226 (Assignments): Clarify default-value example as suggested by
4228 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4229 (Special Shell Variables): Note leading ./ or ../, as suggested
4231 (Limitations of Builtins): Under cd, warn about CDPATH.
4232 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4235 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4237 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4238 `@var', for texi2html.
4239 (Systemology): Some more word wrapping, for DVI output.
4240 (autom4te Invocation): The short option for `--melt' is `-M',
4243 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4245 * doc/autoconf.texi: More formatting and English tweaks,
4246 many suggested by Ralf Wildenhues.
4247 Reword to avoid "@code{...}'s" and the like, since it's ugly
4248 with Emacs info mode. discontents -> woes.
4249 Put a few "will"s back. time stamp -> timestamp.
4250 side-effect -> side effect.
4252 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4254 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4255 Warn about $@ not persisting. Problem reported by Julien Danjou in
4256 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4257 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4258 Mention other special chars, too.
4260 2006-06-14 Eric Blake <ebb9@byu.net>
4262 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4264 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4266 * doc/autoconf.texi: Some systematic minor improvements, as
4267 follows. Use "makefile" when talking about makefiles
4268 generally (which might be named "makefile" or "Makefile" or even
4269 "foo.mk"), "Makefile" when talking about a specific makefile
4270 called "Makefile". This unclutters the text from weird quotes
4271 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4272 values" rather than "@var{foo}s" and similar constructs containing
4273 "}s". Use "Make rules" rather than "Makefile rules". Minor
4274 English-language improvements. Change the prefix "sub-" to "sub"
4276 Put blank lines around examples more consistently.
4277 Avoid "rather" and "very" as intensifiers.
4278 Avoid "will" as an auxiliary.
4279 (Limitations of Make): Split this node into....
4280 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4281 (Leading _ in Macro Names, Backslash-Newline-Newline):
4282 (Backslash-Newline Comments, Long Lines in Makefiles):
4283 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4284 (obj/ and Make, make -k Status, VPATH and Make):
4285 (VPATH and Double-colon, $< in Explicit Rules):
4286 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4287 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4288 New nodes, resulting from splitup of Limitations of Make.
4289 All cross-references changed. Raise the top node from
4290 a section to a chapter, and all subnodes accordingly.
4291 Redo the introductory wording to match the new organization.
4292 (Installation Directory Variables): Use an example that is
4293 closer to what Autoconf actually does. Mention that VPATH's
4294 value should not contain metacharacters or white space.
4295 (Fortran Compiler): Fix a VPATH bug in an example.
4296 (Leading _ in Macro Names): Mention that this problem is no longer
4297 of practical concern.
4298 (VPATH and Make): Reword the advice to make it clearer
4299 that Autoconf and Automake support VPATH in non-GNU make, but
4300 many packages have bugs in this area.
4301 ($< in Explicit Rules): Refer to Build Directories rather
4302 than using a (non-VPATH-safe) example.
4303 (Automatic Rule Rewriting): Mention the sort of disaster that
4304 can ensue with Solaris-style rule rewriting with VPATH.
4306 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4308 * doc/install.texi (Compilers and Options): Weaken the
4309 suggestion to use GNU make for VPATH builds.
4311 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4312 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4314 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4315 in regular expression.
4317 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4319 * doc/autoconf.texi (Installation Directory Variables):
4320 Drop extra @samp from `@table @samp' item.
4321 (Limitations of Usual Tools): Comment fix.
4322 Do not nest @samp just to point to other table items.
4323 (Writing testsuite.at) <AT_CHECK>: The second argument to
4324 `@dvar' is already @samp'ed.
4325 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4326 do not use @var in the second argument.
4328 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4330 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4331 $as_shell.exe too. Problem reported by Andreas Buening in
4332 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4334 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4336 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4337 `unused variable' compiler warning, for `-Wall -Werror'.
4338 Reported by Jaap Haitsma in
4339 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4341 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4343 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4344 case the compiler dumps core. Problem reported for
4345 OpenServer 5.0.7 by Tim Rice in
4346 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4347 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4350 2006-06-06 Tim Rice <tim@multitalents.net>.
4352 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4353 "ERROR" only shows up in "make check" output if there is an

4377 * config/texinfo.tex: Sync from upstream.
4379 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4380 seen, invoke libtoolize with `--ltdl' argument.
4381 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4383 Suggested by Eric Blake.
4385 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

4397 * doc/autoconf.texi: Modernize some of the references to Solaris.
4399 2006-06-05 Stepan Kasal <kasal@ucw.cz>
4401 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
4402 message issued by AC_REQUIRE.
4403 * tests/m4sugar.at: Check m4_require's error message.
4404 * tests/base.at: Check AC_REQUIRE's error message.
4405 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4407 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4409 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4410 `expout' as the last parameter.
4411 * tests/tools.at: Adapt to the above change.
4413 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4415 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4416 information about race-free implementations of mkdir.
4418 2006-06-04 Eric Blake <ebb9@byu.net>
4420 * bin/autoreconf.in (help): Document M4 environment variable.
4421 * bin/autoconf.as (Usage): Likewise.
4422 * bin/autom4te.in (help): Likewise.
4423 * doc/autoconf.texi (autom4te Invocation): Likewise.
4425 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4427 * NEWS: GNU make now recommended for VPATH builds.
4428 Mention that some macros are now documented to be obsolescent.
4429 * doc/autoconf.texi:
4430 Prefer "current" to "modern" to describe
4431 currently-used (albeit perhaps old-fashioned) hosts.
4432 Mention which ancient features no longer need to be worried about.
4433 setgid -> set-group-ID
4434 setuid -> set-user-ID (these are the Posix terms)
4435 Fix some misuses of "only".
4436 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4437 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4438 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
4439 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
4440 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
4441 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
4442 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
4443 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
4444 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
4445 Mention that these macros are obsolescent.
4446 (Installation Directory Variables): shall -> should
4447 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4448 Mention that it's now safe to use 3 and 4.
4449 (Limitations of Usual Tools): cp -r is now specified by Posix.
4450 Omit longwinded and obsolescent discussion of cp -f.
4451 Modernize discussion of expr, ls.
4452 (Limitations of Make): Modernize discussion of VPATH builds.
4453 Mention $? as a workaround in some cases.
4454 * doc/install.texi (Basic Installation):
4455 Mention "./configure; make; make install" first. Be more
4456 specific about why this file is generic. Remove unnecessary
4457 parens. Remove misleading "only". Remove obsolete advice
4458 about csh. Don't say "configure" takes awhile; say it
4459 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4460 and CC=c99 rather than CC=c89, as these are blessed by current
4461 Posix. Recommend GNU make if doing a VPATH build.
4463 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4465 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4466 examples involving shell prompts.
4468 2006-06-02 Stepan Kasal <kasal@ucw.cz>
4469 and Paul Eggert <eggert@cs.ucla.edu>
4471 * doc/autoconf.texi (Here-Documents): Add details about the
4472 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4473 use "here-documents" instead of "here documents".
4475 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4477 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
4479 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
4481 * doc/autoconf.texi (File System Conventions): Warn about ":"
4482 anywhere in directory names.
4484 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4486 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4487 about quoting the case statement, just in case.
4488 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4489 was fixed in ksh93g; reported by Ralf Wildenhues.
4491 2006-05-31 Stepan Kasal <kasal@ucw.cz>
4493 * doc/autoconf.texi (System Services): Do not document
4494 overriding EXEEXT via ac_cv_exeext=ext.
4495 (Particular Programs) <AC_PROG_MKDIR_P>:
4496 Document that ${MKDIR_P} understands --.
4497 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
4500 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4502 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
4503 argument with leading hyphen. Problem reported by Paul Eggert.
4505 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4507 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4508 about quoting ac_try: quote all of it, if any of it seems suspicious.
4509 This means we don't have to worry about ${ or sed any more.
4510 Also, double-quote the case statement, to work around misuses via
4511 underquoting as reported by Ralf Wildenhues in
4512 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4513 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4514 undocumented and dangerous macro.
4515 Problem reported by Ralf Wildenhues in
4516 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
4518 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4520 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
4521 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
4522 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
4524 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4526 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4527 since evidently some packages rely on the old, broken behavior.
4528 Problem reported by Ralf Wildenhues in
4529 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4530 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4531 pre-2006-05-26 definitions, but leave in the comments that
4532 these macros are dangerous and should not be used.
4533 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4534 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4535 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4536 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
4537 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
4539 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4541 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4542 the use of 'tr', since this is our only use of 'tr'.
4544 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4545 and Paul Eggert <eggert@cs.ucla.edu>
4547 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
4548 Don't assume 'grep' works on long lines, since AIX grep doesn't.
4550 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4552 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4553 the output file in the `${datarootdir}' test.
4555 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4556 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4558 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4559 mention of `datarootdir' in the input file(s), but literal
4560 `${datarootdir}' in the output file, and we haven't warned yet,
4561 then warn as well: the user may have (erroneously) used
4562 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4563 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4564 * tests/torture.at (datarootdir workaround): Extend this test.
4567 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4568 and Paul Eggert <eggert@cs.ucla.edu>
4570 * doc/autoconf.texi (autoheader Invocation): The first argument to
4571 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4572 alternatives and clear up the language a bit.
4574 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4576 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4577 ac_config_guess, ac_config_sub, ac_configure.
4578 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4579 Fix typo that prevented an unnecessary space from being removed.
4580 Problems reported by Ralf Wildenhues in:
4581 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4583 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4585 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4586 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4587 Don't use the term "thread-safe" to talk about mkdir race
4588 conditions, since the problem is more a process than a thread
4589 issue. Problem reported by Stepan Kasal in:
4590 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4591 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4592 the test for 'install' more closely. Look at MKDIR_P first.
4593 Look in the PATH, and at /opt/sfw/bin.
4594 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4595 Don't bother to try mkdir -p, since we already check mkdir --version;
4596 just look at the version number. (There's no easy way to check
4597 for race-free implementations.)
4598 * tests/tools.at (autoconf: subdirectories): Adjust to above
4599 changes, since MKDIR_P now might end in "/mkdir -p".
4601 * doc/autoconf.texi (autoheader Invocation): Mention that the
4602 first arg of AC_DEFINE_UNQUOTED must be a literal.
4603 Problem reported by Ben Pfaff in
4604 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4606 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4607 * doc/autoconf.texi (Special Chars in Variables): New section.
4608 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4609 (Installation Directory Variables): Quote $(datadir) better.
4610 (Limitations of Builtins): Describe some of eval's trickiness.
4612 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4613 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4614 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4615 in front of every arg, not just trailing args. Quote apostrophes.
4616 (_AC_EVAL_ECHO): New macro.
4617 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4618 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4620 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4621 exposed by quoting of eval argument. Put the command on line line
4623 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4624 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4625 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4626 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4627 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4628 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4629 Use eval more safely.
4630 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4631 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4633 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4634 lines, exposed by quoting of eval argument.
4636 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4637 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4639 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4640 initialization of `ac_cv_exeext', do not override it if it was
4641 already set, unless it was set to `no', for compatibility with
4642 Autoconf-2.13, and comment this.
4643 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4644 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4645 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4646 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4647 Document that this test may be overridden by setting
4650 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4652 Revert these two patches:
4654 2006-04-06 Eric Blake <ebb9@byu.net>
4655 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4656 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4659 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4660 Clean up _AC_COMPILER_EXEEXT* macros.
4661 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4662 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4663 ac_file to the name of the default output file and call
4664 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4665 initial `rm' of the candidate files...
4666 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4667 the same list in subsequent `rm' calls, and for the temporary
4668 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4669 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4670 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4671 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4672 no longer needed) by libtool. Make it a cache check.
4673 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4674 copied here by mistake.
4675 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4676 _AC_COMPILER_EXEEXT.
4677 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4678 _AC_COMPILER_OBJEXT directly.
4679 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4681 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4683 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4684 Fix description of how the buggy `sed' works.
4686 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4690 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4691 ENOLCK. Only mention `make -j' when applicable. Only raise
4692 fatal errors when `make -j' is involved. Improve error message.
4694 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4696 * doc/autoconf.texi (Here-Documents): We now know more about
4697 the variable expansion in here documents bug.
4698 Thanks to Tim Rice and Stepan Kasal.
4700 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4701 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4703 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4705 * tests/autotest.at (Multiline command from M4 expansion):
4706 No failure to be expected if the shell quotes newlines in
4707 commands in the `set -x' output. Report by Tim Rice.
4710 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4712 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4713 expansion in the here-documents used by config.status, as that
4714 runs afoul of the Korn shell version M-12/28/93d bug described in
4715 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4716 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4717 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4719 2006-05-23 Jim Meyering <jim@meyering.net>
4721 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4722 Fix typo introduced with 2006-04-02 change. It reversed the sense
4725 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4727 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4728 ac_dB slightly, to save bytes in the script.
4729 Max out at 50 lines, rather than 96; this is more likely
4730 (though not guaranteed) to avoid obscure 'sed' failures.
4732 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4734 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4735 `tr -d -' as bad option argument. Work around this by deleting
4736 an unrelated character.
4737 Report by Tim Rice <tim@multitalents.net>.
4739 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4740 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4741 Stepan Kasal <kasal@ucw.cz>
4743 * doc/autoconf.texi (Particular Programs): Do not promise that
4744 we always prefer the GNU version of the program, and that we
4745 search according to PATH; both rules can have exceptions.
4746 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4747 AC_PROG_SED. Move descriptions of limitations
4748 to the Limitations of Usual Tools section.
4749 (Limitations of Usual Tools) <sed>: Mention script length
4750 limitations with Solaris /usr/ucb/sed.
4751 <grep>: Fix wording for empty alternative. Mention that -c and
4752 -l should not be combined, and that -E and -F should not be
4755 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4756 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4758 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4759 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4761 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4763 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4764 AC_DEFINE is now passed to m4_pattern_allow.
4765 * NEWS: Mention that; likewise for AC_SUBST.
4766 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
4767 the parameter to m4_pattern_allow.
4768 * tests/tools.at: Add a check for that.
4770 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4772 * lib/autoconf/status.m4: Fix typos.
4774 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4776 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
4777 only the files that this macro generates.
4779 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4781 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
4782 the HP-UX sed limitation of 99 commands, labels do not count.
4783 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
4785 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
4787 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4789 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4790 Import the following fix from coreutils:
4792 2006-01-13 Jim Meyering <jim@meyering.net>
4794 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
4795 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
4796 not double-quote uses of that variable, to accommodate the rare
4797 case in which getmntent is available in none of the libraries
4798 checked. This happens at least on FreeBSD 5.0.
4800 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4802 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
4803 ac_config_guess, ac_config_sub, and ac_configure, since evidently
4804 some other programs unwisely rely on these undocumented vars.
4805 But put in warning comments about them.
4806 Problem reported by Ralf Wildenhues in
4807 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
4808 * NEWS: Document that these variables are intended to go away.
4810 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4812 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
4813 and set the language to C++ (analogous to the equivalent Fortran
4816 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
4817 * doc/autoconf.texi (C++ Compiler): Document it.
4818 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
4821 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4823 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
4824 that caused config.status to generate 100-command sed scripts; the
4825 portable limit is 99.
4827 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4829 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
4830 variable `ac_d' instead of `d' to avoid infringing namespace.
4831 Report by Ralf Menzel.
4833 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
4835 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
4836 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
4837 * tests/tools.at (autoconf: subdirectories): New test, taken from
4838 the corresponding problem report by Ralf Wildenhues in:
4839 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
4841 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
4842 Quote some uses of shell variables if they might suffer unexpected
4843 globbing. This doesn't fix all instances of quoting problems that
4844 I found, just the easy ones that look safe.
4845 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
4846 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
4847 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
4848 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
4849 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

4853 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
4854 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
4856 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4858 * bin/autoreconf.in ($help): Reword according to the manual.
4859 Suggested by Olly Betts.
4861 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
4862 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4864 * bin/autoreconf.in: Pass the directory argument to
4865 `require_configure_ac'. Fix comment.
4866 * tests/torture.at (Configuring subdirectories): Expose this.
4867 Reported by Olly Betts.
4869 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4871 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
4872 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
4873 Automake as follows:
4875 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
4876 `$configure_in' instead of `configure.in', to preserve
4877 directory component.
4879 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4881 * config/config.guess, config/config.sub, config/texinfo.tex,
4882 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
4884 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4886 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
4887 test for C99 conformance; (bool) 0.5 is an integer constant
4888 expression, but (bool) -0.5 is not. Problem reported by Fedor
4889 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
4891 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4893 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
4894 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
4895 Warn about obsolete install-sh files. Remove stray sentence
4896 fragment and fix cross reference.
4897 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
4898 install -d; this undoes the 2006-05-10 change.
4899 (MKDIR_P): Mark with AN_MAKEVAR.
4900 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
4901 that we don't require $INSTALL to be thread-safe. Move comments
4902 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
4903 of AC_PROG_INSTALL. Output a message saying that we're checking
4904 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
4905 MKDIR_P instead of AC_SUBST.
4906 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
4907 Special magic for MKDIR_P, too.
4908 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
4910 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
4912 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4914 Sync from Automake, as follows:
4916 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4917 * config/install-sh: Initialize IFS, so field splitting isn't
4919 * config/mkinstalldirs: Likewise.
4920 * config/missing: Remove superfluous quotes. Replace all uses of
4921 `[' by `test', for consistency, and for..
4922 * config/missing (sed_minuso, sed_output): New variables.
4923 (autom4te, help2man, makeinfo): Use them. Unifies detection of
4924 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
4925 Fixes `missing' to detect `--output' for help2man. Fixes
4926 PR automake/483. Report by Dennis J. Linse.
4927 (autom4te): Document in `missing --help'.
4929 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4931 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
4932 * config/install-sh: Don't use 'path' to talk about file names,
4933 as per GNU coding standards. Close a race condition reported by Ralf
4934 Wildenhues and Stepan Kasal. There is still a race condition
4935 on hosts that predate Posix 1003.1-1992, but we can't help this.
4936 Don't mishandle weird characters like space on pre-Posix hosts.
4937 Invoke mkdir at most once per dir arg on pre-Posix hosts.
4938 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
4939 AC_PROG_MKDIR_P from AS_MKDIR_P.
4940 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
4941 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
4942 earlier editions are not (including Automake 1.8.3).
4943 Do not suggest mkinstalldirs for thread-safety.
4944 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
4945 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
4946 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
4947 presence of special characters and race conditions.
4948 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
4949 in Autoconf's name space.
4951 2006-05-10 Bruno Haible <bruno@clisp.org>
4952 and Paul Eggert <eggert@cs.ucla.edu>
4954 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
4955 from Automake with minor changes.
4956 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
4958 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4960 * config/install-sh: Update to Automake CVS version, as follows:
4961 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4962 * lib/install-sh: Simplify the expr implementation of dirname.
4963 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
4964 * lib/install-sh: Handle --, and diagnose unknown options.
4966 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4968 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
4969 `./autom4te' to create `./testsuite', since the `all' target
4970 will ensure its presence, but `installcheck' should not create
4971 the uninstalled wrappers.
4973 * tests/torture.at (Unusual Automake input files): Skip if we
4974 detect automake < 1.8.
4976 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4978 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
4979 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
4980 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
4983 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4985 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
4986 munge (multiple) white space and other oddities.
4987 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
4988 single quotes in variable assignment.
4989 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
4990 and similar failures by adding multiple spaces, tabs, and other
4992 Report and different test suggested by Francesco Romani
4993 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
4995 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
4996 single quotes, we only need to search for single quotes; this
4997 both simplifies the search pattern, and makes us less
4998 susceptible to `echo' variations for arguments not containing
5000 (_AC_ARG_VAR_VALIDATE): Likewise.
5002 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5004 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5005 `$*' and IFS concatenation issue with traditional shells and
5006 bash-2.04. Report by Seanster@Seanster.com.
5008 2006-05-03 Bruno Haible <bruno@clisp.org>
5010 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5011 precisely which Mac OS X versions have the od problem.
5013 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5015 * doc/autoconf.texi: Use @option systematically.
5017 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5018 and Bruno Haible <bruno@clisp.org>
5020 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5022 (Integer Overflow): Mention the special case of integer division
5025 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5027 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5028 traditional shells like the Solaris one that do not use the
5029 first IFS character for assembling `$*'.
5030 Prompted by a related report from autoconf_bug@nro.ca.
5032 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5033 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5035 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5036 Mention more problems with the -e option.
5038 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5041 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5043 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5044 in URLs to improve DVI formatted output (requires texinfo 4.6).
5045 (System Services, Systemology, Shellology): Likewise.
5046 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5049 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5051 (Runtime): Fix macro argument names to match description:
5052 `action-if-found' -> `action-if-true' and similarly.
5053 (Obsolete Macros): Likewise.
5054 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5055 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5056 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5058 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5060 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5063 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5066 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5068 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5069 /bin/sh set unsorted output.

5076 (Integer Overflow, Null Pointers, Buffer Overruns):
5077 (Floating Point Portability, Exiting Portably): New sections.
5078 (Writing Test Programs): Fix some langauge. Recommend exiting
5079 with status 1, not merely nonzero. Clarify exit declaration.
5080 (Run Time): Move C exit status stuff to new Exiting Portably section.
5081 (Systemology): Mention Posix and levenez. Update v7 reference.
5082 (Portable Shell): Mention the Posix shell.
5084 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5086 * bin/autoconf.as (me): Replace by as_me.
5088 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5090 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5091 since as_me isn't set yet.
5093 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5095 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5096 a few minor bugs in this area.
5098 * doc/autoconf.texi (Programming in M4sh): Comment out the
5099 documentation of AS_BASENAME, for now.
5100 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5101 (Limitations of Builtins) <basename>: Do not refer to
5103 * bin/autoconf.as (me): Don't use AS_BASENAME.
5104 (dir): Remove the unused variable.
5105 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5106 AS_DETECT_REQUIRED. All uses changed.
5107 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5109 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5110 (AS_BASENAME): Use "basename --" to protect against leading "-".

5113 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5114 (_AS_DIRNAME_PREPARE): Likewise.
5115 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5116 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5117 (AS_DIRNAME): Use "dirname --".
5119 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5121 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5122 of "run time" and "run-time" changed to "runtime", for consistency.
5123 * lib/autoconf/fortran.m4: Likewise (in comment).
5124 * lib/autoconf/functions.m4: Likewise.
5125 * lib/autoconf/general.m4: Likewise.
5126 * lib/autoconf/headers.m4: Likewise.
5128 * doc/autoconf.texi (Run Time): Document the exit status situation
5129 with more accuracy and detail.
5131 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5133 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5134 Archive is not officially `GNU' any more. Update URL.
5135 (Defining Directories): Likewise
5136 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5138 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5140 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5141 newline from the `trap' code to finish `config.log'; the NetBSD
5142 /bin/sh resets the exit status after an empty command, as
5143 documented in doc/autoconf.texi.
5144 Reported by Dalibor Topic <robilad@kaffe.org>.
5146 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5148 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5149 Suggested by Bruno Haible.
5151 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5153 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5154 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5155 Instead, just list the shells that we know work.
5156 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5157 changed. Be more cautious about the _cv_ variable.
5158 * tests/tools.at (Syntax of the shell scripts): Check the
5159 _cv_ variable once, at first, to avoid an internal autoconf error
5160 when sh -n does not work.
5162 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5164 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5166 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5168 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5169 use ">&-" since we're only 99.999% sure that this is portable,
5170 and since the MinGW bug is fixed in a different way.
5171 * lib/autotest/general.m4 (AT_INIT): Likewise.
5173 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5175 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5176 before opening config.log, to avoid hitting a bug on MinGW.
5178 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5180 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5181 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5182 This works around a MinGW bug reported by Eric Paire.
5183 Make sure that all writes to the log file append to it,
5184 rather than possibly losing data.
5185 * lib/autotest/general.m4 (AT_INIT): Likewise.
5187 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5189 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5192 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5196 * configure.ac (AC_INIT): Bump to 2.59d.
5198 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5202 * Makefile.maint (news-date-check): Do not require a leading `*'
5203 before the release date in NEWS.
5205 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5206 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5208 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5209 the instantiated file do not contain the string 'datarootdir'
5210 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5211 @mandir@, replace the reference '${datarootdir}' by the value.
5212 * tests/torture.at (datarootdir workaround): New test.
5213 * NEWS: Advertise this temporary fixup.
5214 Based on a patch by Bruno Haible, reported and analyzed by
5215 Paul Eggert and Noah Misch.
5217 2006-04-12 Eric Blake <ebb9@byu.net>
5219 * tests/autotest.at (Debugging a failed test): Fix comment.
5221 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5223 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5224 all the changes since 2006-04-07.
5226 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5228 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5229 succeeded, but `ln -s file dir' failed, take care to remove the
5230 leftover target before the next test, to prevent its spurious
5231 failure; also make sure `ln file dir' works before selecting it.
5232 Thanks to Keith Marshall for pointing this out.
5235 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5236 assignments in `at_debug_args', so that we put them correctly
5237 in the `run' script.
5238 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5239 Reported by Eric Blake.
5241 2006-04-11 Eric Blake <ebb9@byu.net>
5243 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5244 top-level tests after micro-suite has been run. Used in...
5245 (Debugging a successful test, Debugging script and environment),
5246 (Debugging a failed test): ...these new tests. The first of these
5248 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5249 macro, split out from...
5250 (AT_INIT): ...here, so that using -d also generates a run script.
5251 Document that -d inhibits top-level logging.
5252 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5253 inhibits top-level logging; debug scripts are created.
5255 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5257 * tests/autotest.at (Empty test, Empty check): New test to check it.
5259 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5262 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5264 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5265 the files if a problem appears. Make the empty *.at files
5266 read-only, too. Proposed by Ralf Wildenhues.
5268 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5270 * config/Makefile.am: Add comment to force updated Makefile.in.
5272 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5273 space only patch to this file, this patch causes the Makefile.in
5274 files that include freeze.mk to be updated, and thus have a
5275 newer time stamp again, which in turn makes a pristine CVS
5276 checkout have correct time stamps.
5278 * Makefile.maint (cvs-sv): New macro, to be used..
5279 (config.guess-url_prefix, config.sub-url_prefix)
5280 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5281 point to CVS text checkout of Gnulib files.
5282 (copyright-check): Bump current year.
5283 (announcement): Do not hard-wire `./announce-gen'.
5284 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5286 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5288 (wget_files): Update config.guess, config.sub, texinfo.tex by
5289 `wget-update', now that their URLs work again.
5291 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5293 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5294 Problem noted by Paul D. Smith.

5298 * doc/autoconf.texi: Remove unused words from word list.
5299 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5300 .x-sc_trailing_space: New files.
5302 * doc/standards.texi: Sync from gnulib.
5304 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5305 `LIBOBJDIR' as experimental.
5307 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5308 with a target directory; it's internally implemented as `cp'
5309 anyway, but since Autoconf advertises the possibility to use
5310 a target directory when LN_S is `ln -s', we need to find out.
5311 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5312 analyzed by Keith Marshall <keith.marshall@total.com>.
5316 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5318 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5319 confdefs.h as-is. In general, if it has backslash-newline or the
5320 like, then it doesn't work either to sort or to remove empty
5323 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5325 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.

5329 * lib/autom4te.in (Automake-preselections): Preselect
5332 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5334 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5335 apostrophe within a single-quoted string, as this is the usual
5336 tradition and is easier to read than '"'"'. Don't rely on the
5337 shell treating "$/" like '$/'. Use a more-consistent indenting
5340 2006-04-09 Eric Blake <ebb9@byu.net>
5342 * tests/autotest.at (Backquote command substitution),
5343 (Multiline backquote command substitution): Remove mistaken
5344 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5346 (Parenthetical command substitution, Multiline parenthetical
5347 command substitution): here.
5349 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

5424 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5426 Revert the patch from 2006-04-01 and only improve
5427 _AS_DETECT_BETTER_SHELL:
5429 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5430 skip nonexistent directories.
5431 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5432 only shell candidates which exist.
5433 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5434 * lib/autotest/general.m4 (AT_INIT): No need to give three
5435 parameters to _AS_PATH_WALK.
5437 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
5438 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5440 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
5441 distinguish m4sugar macros.

5443 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
5444 test case by Noah Misch <noah@cs.caltech.edu>.
5446 2006-04-07 Stepan Kasal <kasal@ucw.cz>

5457 * doc/autoconf.texi (Programming in M4sh): Document that
5458 AS_MKDIR_P exits the script on failure.
5459 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5461 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5480 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5482 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5483 whether `set' quotes correctly: redirect stderr of the tested
5484 `set', and use a subshell, for Ultrix; use `sed' instead of
5485 `grep' for zsh `set' which may write binary output; match only
5486 at the beginning of a line, to avoid false positives.
5487 In order to avoid false positives by unrelated variables with
5488 multiline content, put the dump algorithm in a subshell and
5489 unset all variables containing newlines (except some which are
5490 special to the shell). Warn about cache variables that are

5535 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
5536 ac_config_<foo>s again, sometimes normalized, sometimes not.
5537 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
5538 (AC_CONFIG_COMMANDS): Do not do so here.
5539 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
5540 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
5541 2005-07-25 rewrite. Noticed by Noah Misch.
5543 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
5544 _AC_PRESERVE_HELP_ORDER, ...
5545 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
5547 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

5550 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
5551 for --help from Cygnus `configure.'
5553 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

5568 * doc/autoconf.texi (Help Formatting): New node.
5569 * NEWS: Announce AC_PRESERVE_HELP_ORDER.

5595 normalizing it, consistent it with previous releases.
5596 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
5598 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
5600 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
5601 Use simplified args that Eric Blake originally suggested.
5603 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
5605 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
5606 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
5607 Use 'comm' rather than N instances of grep; this also fixes a bug
5608 whereby substrings were incorrectly matched, causing us to not
5609 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
5610 (exclude_list): Exclude empty macros.
5611 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

5662 to log, point to testsuite output tree.
5664 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
5666 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.

5692 Clean up _AC_COMPILER_EXEEXT* macros.
5694 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5695 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5696 ac_file to the name of the default output file and call
5697 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5698 initial `rm' of the candidate files...
5699 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5700 the same list in subsequent `rm' calls, and for the temporary
5701 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,

5703 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5704 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5705 no longer needed) by libtool. Make it a cache check.
5706 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5707 copied here by mistake.

5709 _AC_COMPILER_EXEEXT.

6483 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
6484 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
6485 by the function rather than ignoring it.
6486 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
6487 comparing its address. Intel's interprocedural optimization was
6488 outsmarting the old heuristic. Problem reported by

6493 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

6500 2005-10-04 Stepan Kasal <kasal@ucw.cz>
6502 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
6503 before removing it (chmod -R u+rwx); there are three instances of this.
6505 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6506 Stepan Kasal <kasal@ucw.cz>
6508 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
6509 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
6510 make its content writable before removing it. Remove an errorneous
6511 comment from the end, where the logs of the failed tests are copied
6512 to the main log file.
6514 2005-09-27 Stepan Kasal <kasal@ucw.cz>
6516 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

6521 problems if the testsuite were running too fast.
6523 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
6525 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
6526 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
6527 (which belong to Xt, not X itself). See Debian bug 327655.
6528 * NEWS: Mention this.
6530 2005-09-07 Stepan Kasal <kasal@ucw.cz>
6532 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.

6537 suggested by Ben Elliston. Handle weird characters correctly.
6539 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6541 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6542 calls, so that the final expansion of this macro is shorter.
6543 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6544 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6545 the cleanup there. Use AS_VAR_* macros, to be more general.
6546 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
6548 * lib/autoconf/general.m4: Use AS_IF where appropriate.
6550 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

6565 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6566 The previous patch didn't work, so try a better one.
6568 2005-08-26 Stepan Kasal <kasal@ucw.cz>
6570 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
6571 in the example. Reported by Bruno Haible.
6572 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
6573 "if $undefined_var;" succeeds with my shell.
6575 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6576 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
6577 but change the m4_divert_text to m4_divert_once.
6579 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6581 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6582 Work around bug in Solaris /usr/xpg4/bin/awk.
6583 The bug is present in at least Solaris 8 through 10.
6585 2005-08-24 Stepan Kasal <kasal@ucw.cz>
6587 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
6588 some evil values and relying on the fact that $* concatenates the
6589 parameters by the first character from IFS.
6591 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6592 Stepan Kasal <kasal@ucw.cz>

6595 first header appears, define AH_HEADER.
6596 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6597 Update limitations about when to call AC_CONFIG_HEADERS.
6598 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6599 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6600 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6601 ``Configuration Actions''; fix their index entries.
6603 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6604 options correctly. Process N-M as M-N if M is smaller than N.
6605 Process ranges correctly so that N-N will run only N.
6606 Sort and uniquify the tests that will be run. If there is more
6607 than one test, reinsert the banners for the tests.
6608 * tests/autotest.at (Keywords): Unmark XFAIL.
6610 2005-08-23 Stepan Kasal <kasal@ucw.cz>
6612 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
6613 before passing the macro name to AH_TEMPLATE.
6615 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
6616 now opens log after option processing; in particular, --version
6617 and --help do not touch config.log.
6619 * Makefile.maint: Revert the change from 2005-08-12.
6621 2005-08-22 Stepan Kasal <kasal@ucw.cz>

6627 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6629 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
6630 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
6633 * doc/autoconf.texi (Defining Symbols, Changed Results):
6634 Prepend to LIBS, not append, in examples.
6636 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6638 When building in place, set srcdir="."; suggested by Tim Van Holder.
6640 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6641 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6642 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6643 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
6644 does not mean "no --srcdir option".
6646 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6648 * tests/autoscan.at (autoscan): New file.
6649 * tests/suite.at: Use it.
6650 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
6651 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
6653 * tests/autotest.at (Keywords): Test keywords combinations.
6655 2005-08-12 Stepan Kasal <kasal@ucw.cz>
6657 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
6658 add "2>&1"; gzip 1.2.4 prints help on stderr.
6660 2005-07-27 Stepan Kasal <kasal@ucw.cz>
6662 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
6663 was pushdef'ed twice while popped only once. Push it only once.
6664 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
6666 2005-07-26 Stepan Kasal <kasal@ucw.cz>
6668 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

6675 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
6676 "<tab>" in comment, so that the point is understandable.
6678 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6680 Rewrite substantial part of lib/autoconf/status.m4.
6681 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6682 and CONFIG_COMMANDS are not processed in four separate loops.
6683 Instead, there is one main loop. This alows that the common code
6684 is expanded only once, thus config.status (and configure) is smaller.
6686 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6687 the AC_LIST_FILES and cousins macros are no longer used.
6689 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6690 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6691 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6692 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6693 contain the initialization, nor the for loop, nor the associated
6694 commands; all these go to ...
6695 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6696 _AC_OUTPUT_CONFIG_STATUS.
6697 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6698 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.

6740 parameter to AC_DIAGNOSE.
6741 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.

6744 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent

6843 configure_input, top_builddir, srcdir, etc.
6844 * lib/autotest/general.m4 (AT_INIT): Likewise, for

6855 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

6908 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
6909 the directory specific variables; but don't call it for configure_input.

6913 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
6916 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

6937 variable into diagnostic. Make the diagnostic an error, not a warning,
6938 because we really don't support spaces and suchlike in dir names.
6939 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
6940 Don't worry about backslashes in srcdir; it can't happen now.

6969 (Special Shell Variables): Fix sed code this in the example.
6970 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.

6984 * doc/autoconf.texi:
6985 Don't mention Solaris versions so much, if a
6986 problem is common to all extant versions of Solaris. Say "SunOS
6987 4" instead of "SunOS" for SunOS 4.
6988 (awk): Mention more of the limitations of traditional Awk.

7033 Problem reported by Ralf Menzel.
7035 2005-06-08 Derek Price <derek@ximbiot.com>
7037 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7038 renaming them since they are about to be redefined anyhow.
7040 2005-06-08 Derek Price <derek@ximbiot.com>
7042 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7043 redefined M4 macros to this node. Document m4_include & m4_sinclude.

7049 * doc/autoconf.texi (Introduction): Likewise.
7050 Reword to avoid some formatting glitches.

7053 Redo example output tp match current CVS snapshot.
7054 Use @example.org in email addresses when the examples
7055 might get inadvertently cut-and-pasted into user code.
7056 Remove example of autom4te usage that doesn't seem to work now.

7074 Albert Chin <libtool@mlists.thewrittenword.com> and
7075 Nicolas Joly <njoly@pasteur.fr>.
7077 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7079 m4_cdr of one-member list was [[]] (one-member list containing an
7080 empty string) instead of [] (an empty list. Callers were skewed to
7081 match this misbehaviour. As a consequence of this:
7082 - m4_foreach([x], [], [foo]) expanded to `foo', while
7083 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7084 This bug has been fixed:
7086 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7087 expand to an empty string; print error msg if called without
7089 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7090 misbehaviour; handle [] and [[]] correctly.

7100 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7101 swallow records with more than 99 fields.
7102 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7103 parse the long line.
7105 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7107 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7108 swallow literals longer than 399. Reported by Ralf Wildenhues.
7109 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

7142 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7143 now contain newlines, and substituted files must be referenced on
7144 a line alone; the sed scripts to substitute them are now very

7147 commands can be put in a sed script portably.
7148 * doc/autoconf.texi (Setting Output Variables): Document above

7156 From Ralf Menzel (trivial change).
7158 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7160 * tests/local.at: Don't attempt to check for negated character
7161 classes in shell scripts. The test was too brittle.
7163 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7165 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7166 * doc/autoconf.texi (Limitations of Builtins): Document this
7169 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7171 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7172 common code; used in many places in the tree.
7173 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7174 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7176 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
7178 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
7179 messages when ac_unique_file is not found.
7180 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7181 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7182 commands, for consistency with AC_MSG_ERROR and such.
7184 * bin/autoconf.as: Make more use of "shift 2" in option processing.
7186 * bin/Makefile.am: Merge the two rules for creating scripts.
7188 2005-05-23 Stepan Kasal <kasal@ucw.cz>
7190 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
7191 obsolete; it was never documented.
7192 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
7194 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7196 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7197 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7198 (ac_top_builddir): ... this ...
7199 (ac_top_build_prefix): ... to this; the old name is also kept, for
7200 backward compatibility.
7201 (ac_top_builddir_sub): New variable, without the trailing slash,
7203 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7204 * doc/autoconf.texi (Configuration Actions): Rename
7205 ac_top_builddir to ac_top_build_prefix.
7206 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
7207 at_top_builddir to at_top_build_prefix.
7208 * lib/autotest/general.m4 (AT_INIT): Likewise.
7210 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7212 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
7215 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7217 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7218 argument to m4_foreach. I guess it was necessary in the past,
7219 but I think it's a no-op now.
7221 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7223 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7224 ``cat <<_ACEOF'' commands to one.
7225 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7226 * lib/autoconf/status.m4: On various places, use expr instead of
7228 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7229 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7230 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7232 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7233 the wrong patterns between ``case'' and ``esac.'' The previous
7234 code had false positives.
7236 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7238 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
7240 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

7281 2005-05-13 Stepan Kasal <kasal@ucw.cz>
7283 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
7285 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7286 enough arguments, similarly as in m4_bpatsubsts.
7288 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7290 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
7293 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7295 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7296 for absolute directory names in one loop.
7297 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7298 abbreviations of --version and --debug.
7300 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7302 * doc/autoconf.texi (Autoconf Language): Be more precise about
7303 quoting rules. Problems noted by Stepan Kasal.
7304 Also, throughout this document, be more careful about white space.
7305 "blank", "white space", and "space" all have different meanings
7306 and we should be careful to say what we mean.
7308 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7310 Fix C++ related problems reported by Werner Lemberg.
7311 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7312 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7313 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7314 avoid problems with C++ and throw.
7315 * tests/compile.at: .cpp, not .cc.
7317 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7319 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7321 * doc/autoconf.texi (Generic Functions): Typos.
7323 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7325 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7326 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7327 set by latest automake.
7329 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7331 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7332 outputs 0 on GNU/Linux these days.
7334 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7336 * doc/autoconf.texi (Autoconf Language): Add more description
7337 about quoting heuristics.
7338 (Limitations of Builtins): Describe "set -" problems.
7340 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7342 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7345 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7346 by AC_DEFINE; it was a mistake.
7347 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7349 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7351 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7353 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7355 * doc/autoconf.texi (External Software): Quadrigraphs are not
7356 processed correctly in AS_HELP_STRING; avoid this in the examples.
7357 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7358 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7359 comment and reduce m4_default([foo], []) to [foo].
7360 (m4_strip): Update the explanation.
7362 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7364 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7365 Remove core.conftest.* too; it's generated by Tru64 5.1.
7366 Problem reported by Jennis Pruett.
7367 * lib/autoconf/functions.m4
7368 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7369 Don't bother to remove core files; AC_RUN_IFELSE should do that
7372 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7374 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
7376 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
7378 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
7379 Report from Horst Wente.
7381 2005-04-15 Stepan Kasal <kasal@ucw.cz>
7383 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
7386 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
7388 * doc/autoconf.texi (External Software, Package Options): Add
7389 examples showing how to implement --with-* and --enable-* options.
7391 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7393 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
7394 as well as configure.in. Problem reported by Gregorio Guidi.
7396 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
7398 * doc/autoconf.texi (Particular Functions): Use gnulib's current
7399 pattern for alloca snippet.
7401 2005-04-04 Stepan Kasal <kasal@ucw.cz>
7403 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

7409 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
7411 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
7412 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
7414 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7416 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7417 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7418 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7419 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7420 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7422 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7424 * NEWS: The configure command now warns you if you attempt to use
7425 a directory whose name contains a special character like space,
7427 * doc/autoconf.texi (Installation Directory Variables): Allow
7428 "," in file names. Do not use \@; it's not a portable regexp.
7429 * bin/Makefile.am (edit): Likewise.
7430 * lib/Makefile.am (edit): Likewise.
7431 * tests/Makefile.am (edit): Likewise.
7432 * tests/semantics.at: Likewise.
7433 * tests/torture.at: Likewise.
7434 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
7435 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
7436 * doc/autoconf.texi (File System Conventions): Warn about
7437 unportable file names.
7438 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7440 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7441 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7442 ac_pwd, and quote srcdir.
7443 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7445 * doc/autoconf.texi: Fix some systematic formatting problems.
7446 ".)" needs a following @: if not at the end of a sentence, and
7447 similarly for "!)". "etc." should be preceded by a comma.
7448 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7450 2005-03-22 Bruno Haible <bruno@clisp.org>
7452 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7453 argument is often called 'build-aux'.
7455 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7457 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7458 macro AC_TRY_LINK is obsolete.
7459 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7462 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7464 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7465 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7466 from a Common Lisp's `cl'.
7467 (AC_PROG_CXX): Behave according to the documentation: don't
7468 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7469 make the variable CCC precious; use `cl.exe', not `cl'.
7471 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7472 Alexandre Duret-Lutz <adl@gnu.org>
7474 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7475 /dev/null, as "configure" shouldn't read stdin, and this insulates
7476 us from problems (e.g., when testing for "cl"). Also, do this
7477 redirection before invoking "hostname" or "uname", and keep the
7478 original input stream available via...
7479 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7480 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
7481 bother with "</dev/null" since it's now done at the top of
7483 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
7484 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7485 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7486 * doc/autoconf.texi (File Descriptor Macros): New section.
7487 (Printing Messages): Mention it.
7488 * tests/base.at (Input/Output): New test.
7490 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7492 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7493 newline if neither \c nor -n work, as that would output two
7494 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7496 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7498 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7499 This causes that any required macros inside will get before the if.
7500 * doc/autoconf.texi (autom4te.cache): A typo.
7502 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7504 Undo previous change, except keep the change to
7505 lib/autoconf/programs.m4 that replaced grep with shell
7506 pattern-matching. This is because net-snmp configure reads stdin.
7507 Reported by Noah Misch.
7509 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7511 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7512 from /dev/null, as "configure" shouldn't read stdin, and this
7513 insulates us from problems (e.g., when testing for "cl").
7514 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7515 before invoking "hostname" or "uname".
7516 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7517 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7518 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7519 "</dev/null" since it's now done at the top of 'configure'.
7520 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7521 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7522 Also, replace grep with shell pattern-matching, to save a process.
7524 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
7526 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7527 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
7528 avoid thinking that Allegro Common Lisp's "cl" command is a C++
7531 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
7533 * doc/autoconf.texi (Limitations of Usual Tools): Document that
7534 grep -q isn't portable. Improve grep -s explanation.
7535 Problem reported by Dan Manthey.
7537 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
7539 * doc/autoconf.texi (Special Shell Variables): Clarify
7540 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
7542 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
7544 * doc/autoconf.texi: Use @acronym for DJGPP.
7545 Fix some @code's that should have been @env's, and vice versa.
7546 Sort environment variable names.
7547 Mention that shells no longer inherit IFS.
7548 Don't recommend PATH_SEPARATOR=';' so strongly.
7549 Mention that $RANDOM might expand to the empty string.
7550 "symlink" and "soft link" -> "symbolic link".
7551 Improve mktemp description (reported by Bruno Haible).
7553 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
7555 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
7556 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
7558 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
7561 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
7563 * NEWS: Mention AT_COPYRIGHT.
7565 * tests/local.at (AT_CMP): Use diff directly on input files rather
7568 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
7569 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
7571 2005-02-04 Noah Misch <noah@cs.caltech.edu>
7572 and Paul Eggert <eggert@cs.ucla.edu>
7574 * tests/autotest.at (Empty test suite): New test.
7575 * tests/torture.at (Substitute and define special characters)
7576 (Substitute a 2000-byte string, Define to a 2000-byte string)
7577 (Substitute a newline, Define a newline): New tests.
7579 2005-02-04 Noah Misch <noah@cs.caltech.edu>
7581 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
7582 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
7583 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
7584 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
7585 (Standard regular expressions): New test.
7586 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
7587 excess test name quoting.
7588 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
7589 CPPFLAGS to `configure' instead of setting it in `configure'.
7591 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
7592 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
7595 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
7596 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
7598 * tests/local.at (AT_CMP): New macro.
7599 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

7631 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
7632 Use newline as a separator, not space.

7690 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7691 Update the long comment explaining it.
7693 m4_require no longer writes an ``is required by'' line to the
7694 execution stack. It contains only one bit of non-redundant
7695 information: that the macro was required, not called. And even
7696 this bit is useless in most situations: have you ever met a macro
7697 which both calls and requires the same macro?
7699 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7700 (_m4_defun_pro_outer): ... only via this macro, for the outermost

7708 * tests/m4sugar.at (m4_require): Expect output without the
7709 ``is required by'' messages.

7747 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
7748 Warn about newline stripping in `` and $(). Update Solaris
7750 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7751 X insulates us from future changes to Posix.

7805 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
7806 stored in _m4_divert_diversion or _m4_divert_dump.
7807 (m4_divert_pop): When the parameter is given, compare the symbolic
7808 name with the last diversion pushed on the stack. Previously, the
7809 current diversion was compared with the numeric value of the
7810 diversion given as the parameter.
7811 (m4_require): If the macro hasn't been expanded yet, call ...
7812 (_m4_require_call): this new macro.

8068 * lib/freeze.mk (MY_AUTOM4TE): Wrap the uninstalled autom4te directly.
8069 (m4f_dependencies): Adjust accordingly.
8070 * tests/Makefile.am (Wrappers): Generate wrapper scripts.
8071 (wrapper.in): Generate it in the build directory.
8072 (MAINTAINERCLEANFILES): Delete wrapper.in.
8073 (CLEANFILES): Add wrapper.in.
8074 * tests/wrapper.as: Move AS_INIT to very top, preserving copyright in
8075 the output. Replace each $as_me with a @wrap_program@.
8076 * tests/wrapper.in: Delete it; we always build it.
8078 * bin/Makefile.am (autoconf.in): Generate it in the build directory.
8079 (EXTRA_DIST): Remove autoconf.in.
8080 (CLEANFILES): Add autoconf.in.
8081 (autoconf): Find autoconf.in in the build directory.
8082 * bin/autoconf.in: Delete it; we always build it.
8084 2004-12-08 Noah Misch <noah@cs.caltech.edu>
8086 * lib/autotest/general.m4 (AT_INIT): Replace a `tr' with a `sed'. Join
8087 PATH members so as to not prepend an empty element. Move a comment.
8088 * Makefile.am (SUBDIRS): Build in `tests' last.
8089 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
8091 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
8093 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
8094 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
8095 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
8096 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
8098 2004-12-07 Stepan Kasal <kasal@ucw.cz>
8100 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

8112 out the common code to ...
8113 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
8114 value of the #define--default to 1, iff the macro was called
8115 with exactly one parameter.
8117 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8119 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8120 "char c = '\200';" rather than "char c = 0x80;" as the
8121 latter doesn't conform to the strict C standard due to
8122 overflow on signed char hosts.
8124 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8125 to -qlanglvl=ansi. We don't want to disable extensions.
8127 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
8129 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

8177 * doc/autoconf.texi (Autoconf Language): Explain that
8178 ``descriptions'' may not be double quotes.
8179 (Quotation Rule Of Thumb): Likewise.
8180 (Pretty Help Strings): Likewise; remove the wrong comment;
8181 simplify the examples and improve their quoting.
8183 2004-11-13 Stepan Kasal <kasal@ucw.cz>
8185 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
8186 the $1_found variable, don't test whether the file is executable;
8187 Both things are checked ...
8188 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
8189 the former ``test -f''.

8200 limitations. Reorder paragraphs for clarity.
8202 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
8204 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
8205 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
8206 variants", "Unix", and some related minor wording fixups.
8208 (Shellology, Special Shell Variables): Document that the Zsh
8209 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
8210 to Alexandre Duret-Lutz for this info.

8221 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
8223 * doc/autoconf.texi (auindex): New macro.
8224 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
8225 Problem reported by Stepan Kasal.
8227 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
8229 Fix problems reported by Andreas Buening in:
8230 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
8231 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
8233 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
8234 readable; it's not true in OS/2-emx.
8236 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
8238 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8239 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8240 (trivial change). Problem and patch reported by Andrew Church in:
8241 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
8243 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
8245 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
8246 three args in examples. Problem reported by Frederik Fouvry in:

8270 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8271 texinfo.tex for now (done by hand now).
8272 * Makefile.maint (wget_files, cvs_files):
8273 Remove ansi2knr.c; nobody uses it.
8274 (ansi2knr.c-url_prefix): Remove.
8275 (cvs-update): Fix test for failure. I don't know why it ever
8278 * doc/autoconf.texi: Update URLs, some of which went stale.
8279 Use @uref rather than @href.
8281 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8282 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8284 * config/config.guess, config/config.sub, config/elisp-comp,
8285 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8286 doc/fdl.texi, doc/standards.texi: Sync with master copy.

8294 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
8295 tests/tools.at, tests/torture.at:
8296 Use "file name" rather than "filename" or "path",
8297 to be consistent with the terminology of the GNU coding standards.
8299 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8301 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8302 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8303 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8304 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8306 More fixes to support spaces in the name of the build directory.
8307 This isn't a complete fix but it's an improvement.
8309 * bin/autoconf.as (autom4te_options): New var.
8310 Use it instead of appending to AUTOM4TE, so that we can allow
8311 spaces in the build directory's absolute name.
8312 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8313 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
8314 AT_CHECK_NOESCAPE): Likewise.
8315 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
8316 main program): Likewise.
8318 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
8320 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

8326 * doc/autoconf.texi (Function Portability): Document isinf and
8327 and isnan. From a suggestion by Kevin Ryde.
8329 * lib/Autom4te/General.pm (END): Return correct exit status even
8330 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8332 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8334 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8335 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8336 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8338 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8340 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8341 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8342 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8343 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8344 * lib/autom4te.in (Automake-preselections): Preselect
8345 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8347 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8349 * lib/autom4te.in (Automake-preselections): Preselect
8350 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8353 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8355 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8357 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8358 Document problem with "`""`" in pdksh POSIX mode.
8360 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8362 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8363 with pdksh, too. Problem reported by Patrick Welche via
8365 * doc/autoconf.texi (Shellology): Note that set -o posix is
8366 useful for pkdsh, too.
8368 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8370 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8371 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8372 Don't fail if ENV or BASH_ENV is readonly.
8373 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8374 etc. are read only. Problem reported by Ludovic Courtes.
8376 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8378 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8379 zsh, disable GLOB_SUBST to avoid backslash handling problems.
8382 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8384 * doc/autoconf.texi (File System Conventions): Warn about
8385 names like "aux". Problem reported by Eric Blake.
8387 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8388 by zero instead of array size, so that we can use any arithmetic
8389 constant expression (instead of requiring an integer constant
8390 expression). This allows us to test expressions like DBL_MAX <
8391 LDBL_MAX, which didn't conform to the C standard using the old
8393 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8394 now that we can do floating-point tests at compile time.
8396 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8398 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8399 and LDBL_EPSILON, as the resulting expression isn't an
8400 integer constant expression and violates the C standard.
8401 Problem reported by Nelson H. F. Beebe. Also, check
8402 for "L" suffix, and check that long double doesn't have
8403 worse range or precision than double, that mixed-mode
8404 arithmetic doesn't generate a diagnostic, that double
8405 constants fit in long double.
8407 2004-06-03 Kevin Ryde <user42@zip.com.au>
8409 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8410 malloc(0) and realloc(NULL,size).
8412 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
8415 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8417 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8418 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8421 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8423 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
8424 can be rewritten using if-then-else. Suggested by Bruno Haible.
8426 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8428 * doc/autoconf.texi (testsuite Scripts): Fix typo.
8429 Problem reported by Stepan Kasal.
8431 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8433 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
8434 change). Patch reported by Ralf Wildenhues in
8435 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8437 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8438 function F exists if the compiler and linker let you compile an
8439 expression like (F != 0). Recent versions of GCC optimize away
8440 the reference to F in that case, since every function address must
8441 be nonzero, so the link succeeds even if F does not exist.
8442 Problem reported by Manu in
8443 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8445 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8446 "Unix". Many uses changed.
8447 (Limitations of Builtins): Explain better why the ! command isn't
8450 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8452 * lib/autom4te.in (Automake-preselections): Preselect
8453 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8455 2004-05-19 Kevin Ryde <user42@zip.com.au>
8457 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8458 referencing AC_FUNC_STRERROR_R.
8460 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8461 note pessimistic assumption when cross compiling.
8463 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8465 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8466 (until 2004) invoked subcommands with sh -e, contra POSIX.
8467 Reported by Kevin Ryde.
8469 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8471 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8472 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8473 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8474 `test -f " /usr/bin/grep"', which _always_ failed.
8475 (AC_PROG_SED): Ditto bogus PATH fix.
8476 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8477 requires that grep correctly supports _multiple_ `-e' options, rather
8478 than stating only that grep should accept `-e'.
8480 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8482 Port to C99, which requires that 'exit' be declared.
8484 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8485 to ensure that stdlib.h is included.
8486 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8487 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8488 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8489 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8490 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8491 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8492 when using 'exit' in a test; C99 requires that 'exit' be declared.
8494 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8496 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8497 now prefers 'grep' implementations that accept -e.
8498 (Limitations of Usual Tools): Describe problems of traditional
8499 egrep and fgrep with long input lines, and of traditional grep
8501 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8502 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8503 All callers changed. Append /usr/xpg4/bin to the PATH, for
8505 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8506 the user with complaints about multiple -e options.
8507 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8508 Define it with AC_PROG_GREP.
8509 * configure.ac (AC_PROG_GREP): Add.
8510 * lib/freeze.mk (GREP): New macro.
8512 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8514 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8515 a possible candidate only after all others fail, rather than
8516 consulting it first. This improves backward compatibility by
8517 better reflecting the way shell selection occurred in previous
8518 versions of Autoconf, and should help to avoid triggering latent
8519 problems in other packages, such as the one in Automake where zsh
8520 is not handled robustly:
8521 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8522 Although it is not Autoconf's responsibility to work around
8523 problems in Automake, it nevertheless makes sense to avoid
8524 introducing unnecessary incompatibilites.
8526 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,

8546 paragraph about DJGPP, based on a mail from Richard Dawe.
8548 2004-04-20 Paul Eggert <eggert@twinsun.com>
8550 * tests/c.at (C keywords): Don't assume that GCC supports
8551 "restrict" and "inline", as sufficiently-old GCC versions do not
8552 (also, GCC configured to be in pedantic C89 mode does not).

8572 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8573 best tool so far counter rely on the tool path variable name to

8575 the length check on a previous tool.
8577 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8578 match expression argument, as different greps have different

8715 AC_SUBST provides no portable way to escape literal newlines.
8717 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
8718 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8719 Darwin uses -lcrt2.o and there's little point to cataloging all
8720 the system variants. Partial fix reported by Andreas Waechter in:

8796 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
8797 2003 (except 1997) to the list of copyright years. This undoes
8798 the 2003-05-22 change, which removed the older years from the list.
8799 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

8845 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
8846 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
8847 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
8848 not <inttypes.h>. Problem reported by Tim Mooney in

8850 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
8853 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
8854 otherwise "make check" fails because it forbids cmp (I guess
8855 because cmp treats files as binary on DOS-like systems).

8870 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
8871 -std1 disables some useful extensions on Tru64. Problem reported

8875 2004-01-14 Paul Eggert <eggert@twinsun.com>
8877 * doc/autoconf.texi (Programming in M4sh): Document that
8878 AS_MKDIR_P succeeds if the destination is a symbolic link
8879 to an existing directory.
8880 (Limitations of Usual Tools): Note that mkdir -p might not
8881 succeed on symlinks to directories.

8901 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
8902 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
8903 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
8904 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
8905 AC_COMPILE_IFELSE, since we now assume our caller invokes
8906 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
8907 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
8908 of AC_RUN_IFELSE; this avoids the warning mentioned above.
8909 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
8911 2004-01-07 Paul Eggert <eggert@twinsun.com>
8913 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
8914 `"'...'"`, as it's confusing (and I suspect it may not work on
8915 some platforms). The code was incorrect anyway, as it assumed
8916 that \$ evaluated to itself in that context. Reported by
8917 Alexandre Duret-Lutz.
8919 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

8951 Bug reported by David Relson in
8952 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
8954 * Makefile.am (autom4te-update):

8971 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
8972 -c -o might not work. From a suggestion by Kevin Ryde.
8973 (C Compiler, Generating Sources, Limitations
8974 of Usual Tools, Limitations of Make, Making testsuite Scripts):

9275 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9277 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9278 -mGLOB_options_string stuff for Intel ifc, which can cause
9279 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

9302 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9303 cache variable instead of $G77 to decide whether to include -O2,
9304 since $G77 is specific to Fortran 77.
9306 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9308 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
9309 free" flag. Re-order flags tested into rough order of popularity.
9311 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9313 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9314 arguments so that it can be used with syntax identical to

9390 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9391 directory for AC_CONFIG_COMMANDS' first argument exists.
9392 This makes valid the invocation of _AC_SRCPATH that follows.
9393 Reported by Eric Sunshine.
9394 * doc/autoconf.texi (Configuration Commands): Adjust.

9417 The test suite are sometimes assigning timings incorrectly.
9418 Reported by Henk Krus.
9419 Diagnosed by Nicolas Joly.
9421 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9423 Instead of making AT_help a sequence of assignments to grow

9427 (at_times_skip): Flip the meaning and rename as...

9439 (ifnames): chmod -w.
9440 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9441 executables, not bin/ executables! Otherwise all the magic needed
9442 to find non installed files is turned off. This caused a failure
9443 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9444 as found in its environment (sent by tests/autoreconf): pointing
9445 to bin/autom4te that could not find its files.
9446 * tests/mktests.sh: Force the replacement of generated files, for
9447 the sake of "mv" program that are interactive when overwriting a

9542 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
9544 Add support for newer Fortran dialects. The F77 interface is
9545 unchanged, and continues to support Fortran 77. New FC macros
9546 correspond to all the old F77 macros, with output variables FC,
9547 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
9548 available dialect, but older dialects can be specified. There are
9549 new macros AC_FC_SRCEXT to set the source extension, and
9550 AC_FC_FREEFORM to accept free-form source files.

9650 * bin/autom4te.in: Adjust to output the call stack.

9668 2003-08-21 Akim Demaille <akim@epita.fr>
9670 * bin/autoheader.in (&parse_args): Use &parse_warnings and
9672 ($help): Use Autom4te::ChannelDefs::usage.
9673 * bin/autoscan.in: Use Autom4te::ChannelDefs.
9674 * lib/Autom4te/General.pm: Don't export error: you don't own it.
9676 2003-08-21 Akim Demaille <akim@epita.fr>
9678 First stab at preserving warnings between calls to autom4te,
9679 including when the cache is used.
9681 There are still several issues: (i) there are too many runs of m4
9682 (one for include, one for warnings, and some more), (ii) warnings
9683 spreading on several lines are not handled gracefully, (iii) the
9684 code meant to have the call stack display for errors does not work
9685 (its handling should move from m4 to autom4te).
9687 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9689 (@preselect): Add m4_warn.
9690 ($exit_status): Remove, use $exit_code.
9691 ($help): Use Autom4te::ChannelDefs::usage.
9692 (&handle_m4): No longer define the m4_warnings.
9693 At each run, extract and report the warnings.
9694 Always cache the result, including if the exit status is on
9695 failure, since if nothing changes, we should result in the same
9696 failure, hence we can use the cache.
9697 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9698 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9700 (m4_warn): Redefine as a do-nothing: it is its invocation that
9701 matters, as warnings are now reported via traces.
9702 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9703 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9704 the latter reveals calls to the former.
9708 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
9710 2003-08-21 Akim Demaille <akim@epita.fr>
9712 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
9715 2003-08-21 Akim Demaille <akim@epita.fr>
9717 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
9719 * lib/Autom4te/ChannelDefs.pm: Doc typos.
9720 (&parse_warnings): Accept a list of warning requests.
9721 (&usage): Return a string, not a side effect.
9722 (cross): New warning category.

9726 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
9727 (&require_configure_ac): Accept an optional directory argument.
9728 ($configure_ac): Remove.
9729 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
9731 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
9732 * bin/autoscan.in: Adjust.
9734 2003-08-20 Akim Demaille <akim@epita.fr>
9736 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
9737 Reported by Alexandre Duret-Lutz.
9739 2003-08-20 Akim Demaille <akim@epita.fr>
9741 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
9742 * bin/autom4te: Adjust.
9743 In particular, be Autoconf tools are really silent when properly
9744 working, bind the verbosity of the 'note' channel to $verbose.
9745 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
9746 (&xsystem, &contents): Remove, since they are exported by...
9747 * lib/Autom4te/FileUtils.pm: this.
9749 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
9750 * lib/Autom4te/FileUtils.pm: here.

9805 2003-08-14 Derek Price <derek@ximbiot.com>
9807 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
9808 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
9809 shorter column three. Add DESCRIPTION to log file content.
9811 2003-08-13 Derek Price <derek@ximbiot.com>
9813 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
9816 2003-08-12 Derek Price <derek@ximbiot.com>

9865 From Gareth McCaughan.
9867 2003-06-23 Akim Demaille <akim@epita.fr>
9869 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
9870 not all of them. This fixes 1. the fact that when testing
9871 Autoconf there are many many config.log, 2. the incorrect use of
9872 top_srcdir to find config.log.
9873 Don't mix the detailed output of failed test with the summary of
9874 failures. Rather, append detailed log afterwards.

9993 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
9994 Remove `#include <stdlib.h>' from the list; we should never

9996 resulting namespace pollution would cause other tests to fail.
9997 Configure scripts run with some older versions of g++ and HP's
9998 aCC would fail due to such an #include. Problems reported by

10002 In the test, use the test declaration before including <stdlib.h>,
10003 as that's closer to how it'll be used.
10005 2003-05-23 Akim Demaille <akim@epita.fr>
10007 * doc/autoconf.texi (Header Portability): ucred.h.
10010 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10012 Overhaul Autotest's logging: generate separate log files
10013 in testsuite.dir/NNN/testsuite.log, and append them to
10014 testsuite.log instead of re-running the test verbosely.
10016 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10017 file descriptor, write 0 to at_status_file instead of setting
10018 at_status=0, initialize some new variables (at_status_file,
10019 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10020 to rerun the tests, instead append the at_group_log to the
10021 at_suite_log when a test fails.
10022 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10023 with the AS_MESSAGE_LOG_FD redirected to stdout.
10024 (AT_CLEANUP): save the output status in $at_status_file
10025 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10026 its original place.
10027 (AT_CHECK): since tests are run with a redirected stdout,
10028 and used to be re-run in verbose mode, turn some $at_verbose
10029 into echo, and don't redirect the output of testing stdout
10032 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10033 the name of the debugging directory and information about

10153 2003-05-06 Akim Demaille <akim@epita.fr>
10155 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10156 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10157 by aclocal.m4 is changed it might require the importing of another
10158 m4 extension file, i.e., aclocal must be run.
10160 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10161 (&parse_args): Use --force with aclocal if required and supported.

10175 2003-04-29 Derek Price <derek@ximbiot.com>
10177 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10178 seperator with m4_append_uniq(). It doesn't work.
10179 (AT_CLEANUP): Add `;' to end of at_help_all.
10180 (AT_INIT): Allow --keywords to be specified more than once. When
10181 grepping $at_help_all for keywords, use the field and keyword

10187 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10188 align better with others. I also made some of the individual
10189 entries on one line, for brevity and to make it easier for me to
10190 sort my dir-example file in the Texinfo distribution :).

10410 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10411 innocuous variant befor including <limits.h> or <assert.h>. This

10413 (and earlier versions) have a <limits.h> that declares
10414 gettimeofday and many other functions.
10416 2002-12-03 Paul Eggert <eggert@twinsun.com>

10430 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10431 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10432 defined, to support freestanding compilers. This should fix the
10433 bug reported by Momchil Velkov in
10434 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10436 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10437 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

10472 * Makefile.maint: Sync with Bison, i.e.:
10473 (po-check): Scan .l and .y files instead of the
10474 .c and the .h files that they generate. This fixes the bug
10475 reported by Tim Van Holder in:
10476 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>

10499 option. Process --recheck after parsing all options. Pass -q
10500 option to configure on --recheck.

10536 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10538 We _have_ to stop using the old compatibility scheme that tried to
10539 avoid useless backslashes because Libtool 1.4.3 contains a
10540 AC_DEFINE([error_t], [int],
10541 [Define to a type to use for \`error_t' if it is not
10542 otherwise available.])
10543 We _have_ to quote the single quote and backslashes with \. The
10544 old compatibility scheme saw that ` was backslashed, and therefore
10545 did not quote the single quote. Hence before this patch, Autoconf
10546 was not compatible with Libtool.

10987 2002-10-11 Akim Demaille <akim@epita.fr>
10989 * tests/torture.at (AC_ARG_VAR): Have configure report the value
10992 2002-10-11 Akim Demaille <akim@epita.fr>
10994 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
10995 file name to enable parallel executions.
10996 From Sam Varshavchik.
10998 2002-10-08 Akim Demaille <akim@epita.fr>
11000 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11001 aclocal invocation, as Gettext macros might not be visible to
11003 Instead of blindly running autopoint, scan configure.ac (not the
11004 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11005 Reported by Paul D. Smith.
11007 2002-10-08 Paul Eggert <eggert@twinsun.com>
11009 Work around problems found when POSIXLY_CORRECT=1 is set.
11010 None of this seems to have anything to do with POSIX, really,
11011 but it's how Perl getopt works.
11012 * bin/autom4te.in (parse_args): Configure GetOpt with
11014 * doc/autoconf.texi (Invoking autom4te):
11015 --warning -> --warnings.
11016 * lib/autom4te.in: --warning -> --warnings.
11018 2002-09-28 Akim Demaille <akim@epita.fr>
11020 * doc/autoconf.texi (autom4te.cache): New section.
11022 2002-09-28 Akim Demaille <akim@epita.fr>
11024 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
11025 (Automake-preselections): Update.
11026 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
11028 2002-09-28 Akim Demaille <akim@epita.fr>
11030 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
11031 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
11032 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11033 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
11035 2002-09-28 Akim Demaille <akim@epita.fr>
11037 * tests/torture.at (Configuring subdirectories): Be robust to
11038 users who use config.site to require for a cache: in this case,
11039 the two last configure runs, using two different sets of
11040 arguments, trigger a legitimate error.
11042 2002-09-28 Akim Demaille <akim@epita.fr>
11044 * tests/m4sh.at (Functions Support, Functions and return Support):
11047 2002-09-28 Akim Demaille <akim@epita.fr>
11049 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
11050 autoheader are Perl programs.
11051 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
11052 (autom4te): Specify that the sources are in the $srcdir.
11053 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11055 2002-09-28 Akim Demaille <akim@epita.fr>

11058 (tm_zone): Move their rules to...
11059 * lib/autoconf/types.m4: here, using AN_ macros.
11060 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11061 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11062 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
11063 * lib/autoconf/programs.m4: here.

11065 (ETAGS_FOR_AUTOCONF): New.
11068 2002-09-28 Akim Demaille <akim@epita.fr>
11070 * lib/autoconf/autoscan.m4: New file.
11071 * lib/autoconf/autoconf.m4: Include it.
11072 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
11073 that were listed in the original autoscan.list.
11074 * lib/autoconf/headers.m4: Similarly with headers.
11075 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11076 (.m4.m4f): Don't pass --prepend-include, since that's done by
11077 tests/autom4te itself.
11078 * lib/autoscan/Makefile.am: Include freeze.mk.
11079 (autoscan.list): New target --this file is no longer a source.
11080 (autoscan.pre): New file.
11082 2002-09-28 Akim Demaille <akim@epita.fr>
11084 * bin/autoscan.in (@kinds): Make them singular.
11086 (&init_tables): When --debug, report the list of rules to ease
11087 tracking changes in autoscan.list.
11088 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11090 2002-09-28 Akim Demaille <akim@epita.fr>
11092 * lib/autoscan/functions, lib/autoscan/headers,
11093 * lib/autoscan/identifiers, lib/autoscan/makevars,
11094 * lib/autoscan/programs: Merge into...
11095 * lib/autoscan/autoscan.list: this.
11096 * bin/autoscan.in (&init_tables): Adjust.
11098 2002-09-28 Akim Demaille <akim@epita.fr>
11100 * lib/autoscan/functions, lib/autoscan/headers,
11101 * lib/autoscan/identifiers, lib/autoscan/makevars,
11102 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11103 `functions' line is now prefixed with `function:'.
11104 * bin/autoscan.in (&init_tables): Adjust.
11106 2002-09-28 Akim Demaille <akim@epita.fr>
11108 From now on, autoscan files must always map a macro name to a
11109 word: there is no `default' macro for autoscan.
11111 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11113 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11116 2002-09-28 Akim Demaille <akim@epita.fr>
11118 * bin/autoscan.in (%c_keywords): Remove.
11119 (&used): Keep only track of the words we might be interested in.
11120 (&output_kind): It is no longer needed to look for non active
11123 2002-09-27 Akim Demaille <akim@epita.fr>
11125 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
11126 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
11127 * lib/autoscan/functions: Adjust.
11128 * doc/autoconf.texi (Particular Functions): Adjust.
11130 2002-09-27 Akim Demaille <akim@epita.fr>
11132 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
11134 Thanks to Bill Moseley and Paul Eggert.
11135 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
11136 the tmpdir must be created.
11137 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
11138 dir be in the build tree, instead of $TMPDIR.
11140 2002-09-27 Akim Demaille <akim@epita.fr>
11142 * bin/autoscan.in: Improve the comments.
11143 (&parse_args): Drop obsolete undocumented options.
11144 (&output_kind): Output warnings.
11145 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
11146 (getwd): Trigger a warning.
11148 2002-09-26 Akim Demaille <akim@epita.fr>
11150 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
11151 Reported by Ralf Corsepius.
11152 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11154 2002-09-26 Akim Demaille <akim@epita.fr>
11156 Single suffix rules and seperated dependencies are not portable.
11158 * doc/autoconf.texi (Installation Directory Variables): Update.
11159 (Limitations of Make): Some about `Single Suffix Rules and
11160 Separated Dependencies'.
11161 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11162 (ifnames, autoscan, autom4te): Un-factor into several rules.
11164 2002-09-25 Paul Eggert <eggert@twinsun.com>
11166 * BUGS (Interoperability bugs): New section. Mention libtool
11167 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11169 2002-09-24 Paul Eggert <eggert@twinsun.com>
11171 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11172 make handles suffix-rules differently from GNU make.
11174 * bin/Makefile.am (SUFFIXES, .in): Remove.
11175 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
11176 Move the body of the old .in rule here.
11178 2002-09-16 Akim Demaille <akim@epita.fr>
11180 i960 compilers create `b.out' files by default.
11181 Reported by Ralf Corsepius.
11183 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
11184 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11186 2002-09-13 Paul Eggert <eggert@twinsun.com>
11188 * doc/autoconf.texi (Particular Headers): Remove obsolete
11189 reference to `struct timezone' in the description of
11192 2002-09-13 Akim Demaille <akim@epita.fr>
11196 * config/config.sub, config/config.guess: Update.
11197 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
11198 * Makefile.am: Adjust.
11200 2002-09-13 Akim Demaille <akim@epita.fr>
11202 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11203 reading config.log when the compiler is rejected.
11204 Suggested by Guido Draheim.
11206 2002-09-13 Akim Demaille <akim@epita.fr>
11208 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11209 (chdir_init) might hang when stat'ing mounted directories.
11210 Reported by Vance Shipley.
11212 2002-09-12 Akim Demaille <akim@epita.fr>
11214 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11217 2002-09-12 Akim Demaille <akim@epita.fr>
11219 * doc/autoconf.texi (Defining Symbols): Present two different
11220 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11221 difference between 1 argument calls, and 2-3 argument calls.
11223 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11225 * doc/autoconf.texi: Review grammar and punctuation.
11227 2002-09-11 Paul Eggert <eggert@twinsun.com>
11229 * doc/autoconf.texi: Fix minor formatting, spelling, and
11231 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11232 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11235 2002-09-11 Akim Demaille <akim@epita.fr>
11237 * doc/autoconf.texi (Questions): Rename as...
11239 (Defining Directories): New.
11241 2002-09-09 Akim Demaille <akim@epita.fr>
11243 * doc/autoconf.texi (Making testsuite Scripts): Update.
11244 Suggested by Nishio Futoshi.
11246 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
11248 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
11249 plain `@' is wanted.
11251 2002-09-09 Akim Demaille <akim@epita.fr>
11253 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11254 `duplicates', since the algorithm was too naive and could keep
11255 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11256 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11257 Reported by Ralf Corsepius.
11258 * tests/torture.at (Configuring subdirectories): Exercise these
11261 2002-09-09 Akim Demaille <akim@epita.fr>
11263 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11264 looking for a replacement file.
11265 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11266 directory is relative.
11267 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11268 directory definition.
11269 Reported by Andreas Schwab and Jim Meyering.
11271 2002-09-06 Akim Demaille <akim@epita.fr>
11273 * doc/autoconf.texi (Setting Output Variables): Clarify what
11274 precious variables are.
11275 Suggested by Pontus Skoeld.
11277 2002-09-05 Akim Demaille <akim@epita.fr>
11279 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11280 (ifnames, autoscan, autom4te): Since we don't only depend on
11281 configure.ac variables (such as VERSION etc.), but also on prefix
11282 and so forth, depend on Makefile, not configure.ac.
11283 Reported by Alexandre Duret-Lutz.
11284 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11286 2002-09-05 Kevin Ryde <user42@zip.com.au>
11288 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11289 doesn't seem to be confined to ia64, just say "some versions".
11291 2002-09-04 Akim Demaille <akim@epita.fr>
11293 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11295 * Makefile.am (maintainer-clean-local): Remove.
11296 (MAINTAINERCLEANFILES): Remove COPYING.
11298 2002-09-03 Paul Eggert <eggert@twinsun.com>
11300 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11301 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11304 2002-09-03 Akim Demaille <akim@epita.fr>
11306 * configure.ac: Bump to 2.53d.
11307 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11308 as of today, on Automake's team suggestion.
11310 2002-09-03 Akim Demaille <akim@epita.fr>
11314 2002-09-02 Akim Demaille <akim@epita.fr>
11316 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11318 * configure.ac: Disable SITE_MACRO_DIR.
11320 2002-09-02 Jim Meyering <meyering@lucent.com>
11322 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11323 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11324 Also, tweak grammar: s/make sure to/be sure to/.
11326 2002-09-02 Paul Eggert <eggert@twinsun.com>
11328 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11329 directory names are generally preferable to physical names.
11331 2002-09-02 Akim Demaille <akim@epita.fr>
11333 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11334 Reported by Raja R. Harinath.
11335 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11336 * bin/autoupdate.in: Use error instead of die.
11338 2002-09-01 Paul Eggert <eggert@twinsun.com>
11340 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11341 ordinary shell concatenation rather than echo+tr+sed command that
11342 runs afoul of a long-line-related sed bug in Solaris 8.
11344 * bin/autoheader.in (parse_args): --warning -> --warnings.
11346 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11347 stdout, as traditional "ls" does.
11348 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11349 _AC_COMPILER_EXEEXT_O): Likewise.
11350 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11352 * bin/autoconf.as: Add --prepend-include option. This patch was
11353 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11354 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11356 * bin/autoconf.in, configure: Regenerate.
11358 * doc/autoconf.texi (Special Shell Variables): Mention
11359 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11361 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11362 MAILPATH and set PS1, PS2, PS4 to default values, to work
11363 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11364 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11365 the Autoconf documentation specifies; fall back to "unset" only if
11366 this fails. Use a shell for-loop for this rather than an m4 loop,
11367 to shorten the output script.
11369 2002-08-30 Paul Eggert <eggert@twinsun.com>
11371 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11372 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11373 for the CDPATH problem. Document PWD.
11374 (Limitations of Builtins): Document the problem that "cd $foo" and
11375 "ls $foo" may refer to different directories in shells conforming
11376 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11377 example, since the old example is now out of date.
11379 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11380 FOO" and "ls FOO" talk about different directories; this catches
11381 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11384 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11385 of rolling our own unset.
11386 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11387 in practice we needn't worry about CDPATH if unset doesn't work.
11389 * Makefile.in, aclocal.m4, bin/Makefile.in,
11390 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11391 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
11392 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
11393 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11394 tests/Makefile.in: Regenerate with Automake 1.6.3.
11396 * config/config.guess, config/config.sub, config/mkinstalldirs:
11399 * configure: Regenerate with self.
11401 2002-08-30 Kevin Ryde <user42@zip.com.au>
11403 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
11406 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
11408 * bin/autom4te.in (Request::load): Correctly test for "do" read
11411 2002-08-29 Akim Demaille <akim@epita.fr>
11413 * lib/Autom4te/General.pm (&xqx): New.
11414 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11415 hand, which is not portable.
11417 * bin/autom4te.in: Use them.
11418 Use &error instead of die.
11419 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11422 2002-08-17 Paul Eggert <eggert@twinsun.com>
11424 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11425 default list of compilers to try, since it was long ago superseded
11426 by the ksh fc builtin. Suggested by Steven G. Johnson.
11428 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11430 * doc/autoconf.texi (Invoking autom4te): End the option table,
11431 fixing a bug introduced by the previous patch.
11432 (Limitations of Make): Add a 'target lookup' subentry in the
11433 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11435 2002-07-29 Mark D. Roth <roth@feep.net>
11437 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11438 options and use $AUTOM4TE_PATH.
11439 * doc/autoconf.texi: Remove documentation of autom4te
11440 --include-envvar and --site-macro-subdir options and document
11441 use of $AUTOM4TE_PATH.
11442 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11443 arguments from each language section.
11445 2002-07-29 Paul Eggert <eggert@twinsun.com>
11447 * doc/install.texi: Include copyright symbol in copyright notice.
11449 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11451 (AM_MAKEINFOFLAGS): New macro.
11452 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11453 * Makefile.am (INSTALL): Use the new macros.
11454 Use -o rather than --output, since "missing" does not grok --output.
11456 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11458 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11459 comments do not always work. Never trust the exit status of
11462 2002-07-24 Kevin Ryde <user42@zip.com.au>
11464 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
11465 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
11467 2002-07-23 Paul Eggert <eggert@twinsun.com>
11469 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
11470 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
11471 apparently treats PATH="nonexistent" as if it contained ".".
11472 Bug reported by Stefan `Sec' Zehl.

11742 This improves on an earlier suggestion by H. Peter Anvin.
11744 2002-05-16 Paul Eggert <eggert@twinsun.com>
11746 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11747 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11748 Both macros now accept an optional source-dir arg.
11749 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11751 * NEWS: Document this.
11752 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11754 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11755 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11756 not for GNU extensions; this undoes part of the 2000-11-03 change,
11757 reverting to 2.13-compatible behavior.

11765 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
11766 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,

11768 Bug reported by Stephen Gildea.
11770 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
11771 If prototypes are supported, use them to check this at compile-time,
11772 instead of trying to check it at run-time. If we must do a run-time
11773 check, assume that setvbuf is standard when cross-compiling, as
11774 nonstandard setvbuf occurs only on ancient and unlikely hosts.
11775 Bug reported by Paul D. Smith.
11777 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
11778 argument specifying location of getloadavg.c. This removes a
11779 FIXME. This idea was taken from Jim Meyering's implementation in
11781 * doc/autoconf.texi (Particular Functions): Document this.
11782 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
11783 that's what the code does; this fixes a bug reported by

11788 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
11789 autopoint instead of gettextize.
11790 ($uses_alocal): Rename as...
11791 ($uses_aclocal): this.
11792 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11793 Suggested by Bruno Haible.

11799 2002-04-29 Paul Eggert <eggert@twinsun.com>
11801 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
11802 files to be 1 second older; just set them to be the same time.
11803 Also, sleep 1 second after the first aclocal, to work around
11804 problems with sub-second time stamps on the input files.
11806 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
11808 * doc/autoconf.texi: Mention "set -e -x" lossage

11815 From Christian Cornelssen.
11817 2002-04-29 Akim Demaille <akim@epita.fr>
11819 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
11820 of lack of $LINENO support, then the test will compare the $LINENO
11821 in testsuite vs. the lineno in the test file. This is wrong, of
11823 Be sure to protect it.
11824 Reported by Patrick Welche.
11826 2002-04-25 Akim Demaille <akim@epita.fr>
11828 * doc/autoconf.texi (Obsolete Macros): Typo.
11829 Reported by Vladimir Volovich.
11831 2002-04-25 Akim Demaille <akim@epita.fr>
11833 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
11834 than some of the input files, hence, on the second run of aclocal,
11835 if some of its input are younger, make them older.
11836 Suggested by Paul Eggert.
11838 2002-04-25 Akim Demaille <akim@epita.fr>
11840 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

11846 and ac_subst_vars be sh variables containing the list of
11847 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
11849 (_AC_INIT_PREPARE): Use them to log them.
11850 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
11851 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
11852 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
11853 _AC_SUBST_FILES and _AC_SUBST_VARS.
11854 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
11856 2002-04-24 Akim Demaille <akim@epita.fr>
11858 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
11859 autoheader, so that automake does not complain about a missing
11860 config.h.in that was to be created.
11862 2002-04-23 Akim Demaille <akim@epita.fr>

11955 2002-04-10 Akim Demaille <akim@epita.fr>
11957 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
11958 workaround for ${1+"$@"}.
11959 * doc/autoconf.texi (Shell Substitutions): Explain it.
11960 From Oliver Kiddle and Peter Stephenson.
11962 Have M4sh perform minimal shell sanitizing.
11964 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
11966 (_AS_PREPARE): this new macro.
11968 (AS_INIT): Invoke AS_SHELL_SANITIZE.
11969 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
11971 Adjust Autoconf and Autotest.
11973 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
11974 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
11975 * lib/autotest/general.m4 (AT_INIT): Likewise.
11976 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
11977 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
11980 Use this M4sh to generate Autoconf's shell scripts.
11982 * tests/wrapsh.as: New, precursor of wrapsh.in.
11983 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
11984 on Autotest and M4sh.
11985 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
11986 (wrapsh.in): New target.
11987 * bin/autoconf.as: New, precursor of autoconf.in.
11988 (autoconf.in): New target.
11990 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
11992 * doc/autoconf.texi (Limitations of Make): Mention the issue
11993 with indented comments in rules.

11997 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
11998 ac_top_builddir when setting ac_abs_top_builddir.

12002 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12003 (Portable Shell): Cross reference to Systemology.
12005 2002-04-05 Akim Demaille <akim@epita.fr>

12008 directories when descending in a SUBDIRS.
12009 Reported by Ezra Peisach.
12011 2002-04-04 Andreas Schwab <schwab@suse.de>
12013 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12014 contains no literal separators.
12016 2002-04-03 Akim Demaille <akim@epita.fr>
12018 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12019 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12020 Use dnl, not the KILL diversion.
12022 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12023 (AC_CONFIG_LINKS): here.
12025 Don't use the KILL diversion, as it kills spurious output, which
12026 results in failures being hidden.
12027 Use m4_defn where appropriate.
12028 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12029 after the second argument.
12031 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12032 syntax, as it is provided by M4sugar.
12033 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12035 2002-04-03 Andreas Schwab <schwab@suse.de>
12037 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
12038 expanded if $# <= 2.
12040 * bin/autoreconf.in (autoreconf): Run automake after rerunning
12043 2002-04-03 Akim Demaille <akim@epita.fr>

12049 (_AC_COMPILER_OBJEXT): Use them.
12050 Fixes Debian #138666.
12052 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12054 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12056 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12057 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12058 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12059 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12060 (AC_C_CONST): Same.
12061 (AC_C_INLINE): Same.
12062 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
12063 * doc/autoconf.texi, NEWS: Document.
12064 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and

12070 _AS_MKDIR_P_PREPARE.
12072 2002-03-28 Kevin Ryde <user42@zip.com.au>
12074 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12075 to avoid versions of HP C which don't allow that.
12077 2002-03-27 Paul Eggert <eggert@twinsun.com>
12079 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12080 (AS_SHELL_SANITIZE): Invoke it.
12081 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
12083 2002-03-26 Akim Demaille <akim@epita.fr>
12085 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
12087 2002-03-26 Akim Demaille <akim@epita.fr>
12089 * doc/autoconf.texi (Introduction): The GNATS base moved.
12091 2002-03-25 Paul Eggert <eggert@twinsun.com>
12093 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12094 as POSIX requires, as it doesn't work with Zsh.
12095 * doc/autoconf.texi (Assignments): Document the problem.
12097 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12099 * doc/autoconf.texi (Limitations of Make): Mention more issue
12100 about VPATH, overriding of macros in sub-makes, and handling of
12103 2002-03-21 Paul Eggert <eggert@twinsun.com>
12105 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12106 problem with here-document buffer boundaries.
12108 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12109 when reinvoking the shell, to work around problems with installers
12110 who put strange things like "cd" commands in their environments.
12112 2002-03-19 Akim Demaille <akim@epita.fr>
12114 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12117 2002-03-19 Akim Demaille <akim@epita.fr>
12119 * bin/autoscan.in (scan_file): Specify the location in `&used'
12123 2002-03-19 Akim Demaille <akim@epita.fr>
12125 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
12126 From Nishio Futoshi.
12128 2002-03-19 Akim Demaille <akim@epita.fr>
12130 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

12134 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12135 (Limitations of Usual Tools): Add mkdir section.
12137 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12138 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12139 back on AS_DIRNAME to compute prefixes otherwise; this is
12140 roughly what mkinstalldirs does. That way, we need not have
12141 our own filename disassembler. The old disassembler did not
12142 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12144 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12145 Create at_test_all by a series of assignments,
12146 not by a single assignment of a long string. The latter causes ksh
12147 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12148 presumably because of a buffer overrun.
12150 2002-03-14 Paul Eggert <eggert@twinsun.com>
12152 * lib/autotest/general.m4 (at_times_skip):
12153 Renamed from at_times. Now a boolean.
12154 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12155 says 'times: not found'.
12157 2002-03-14 Akim Demaille <akim@epita.fr>
12159 * bin/autoreconf.in (&study_gettextize): New.
12160 (&autoreconf): Handle newest gettextize.
12161 Rerun aclocal if needed.
12162 Suggested by Andreas Schwab.
12164 2002-03-13 Akim Demaille <akim@epita.fr>

12171 Add information about stdint.h and inttypes.h from Paul Eggert.
12173 2002-03-13 Akim Demaille <akim@epita.fr>
12175 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
12179 2002-03-12 Akim Demaille <akim@epita.fr>
12181 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
12184 2002-03-11 Andreas Schwab <schwab@suse.de>
12186 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
12187 does not do it if --with-lispdir is given.
12189 2002-03-08 Akim Demaille <akim@epita.fr>
12193 2002-03-08 Akim Demaille <akim@epita.fr>

12196 subdirectory should exist.
12198 2002-03-08 Akim Demaille <akim@epita.fr>
12200 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12202 2002-03-08 Akim Demaille <akim@epita.fr>
12204 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12205 aliases the actual variables, and modifications of the former
12208 2002-03-08 Akim Demaille <akim@epita.fr>
12210 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12211 because of C-c: have m4 output in tmp files, then mv them.
12213 2002-03-08 Akim Demaille <akim@epita.fr>
12215 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
12216 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
12217 * bin/ifnames.in: Copyright update.

12232 2002-03-04 Akim Demaille <akim@epita.fr>
12234 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
12235 * lib/autoconf/general.m4 (AC_INIT): More informative error
12236 message for LIBOBJ.
12238 2002-03-04 Akim Demaille <akim@epita.fr>
12240 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
12243 2002-03-04 Akim Demaille <akim@epita.fr>
12245 * doc/autoconf.texi (Transforming Names): Equality between target
12246 and host is irrelevant.
12247 (Specifying Names, Canonicalizing): Remove all references to the
12248 backward compatibility hooks. Rather, collect them all into...
12249 (Hosts and Cross-Compilation): this new section.
12250 * doc/install.texi (System Type): Ditto.
12251 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12252 that `--host' implies cross-compilation.
12254 2002-03-04 Akim Demaille <akim@epita.fr>
12256 * doc/autoconf.texi (Evaluation Macros): New.
12257 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12259 (_m4_foreach): Define the variant with immediate evaluation so
12260 that it contains exactly the items, not an expression which
12261 evaluation is the current item.
12262 (m4_re_string, m4_re_word): Don't over quote them.
12264 2002-03-04 Akim Demaille <akim@epita.fr>
12266 Instead of having stacking `shift's evaluated at the end, let
12267 `foreach' loops immediately evaluate them.
12269 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12270 $*. This is the n-th time I change my mind, but hopefully this is
12273 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12275 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12276 it was only a hack for m4_text_wrap.
12277 (m4_car2): Remove, replaced by...
12279 (_m4_foreach): Adjust.
12280 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12281 m4_bpatsubst for clarification.
12283 2002-03-04 Akim Demaille <akim@epita.fr>

12311 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
12312 From Akinori Musha.
12314 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>

12330 2002-02-07 Akim Demaille <akim@epita.fr>
12332 Fix Autoconf PR/207:
12333 AC_PREFIX_PROGRAM fails with dashed program names
12335 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
12336 variable when looking for the prefix program.
12337 Now it also works for shell variables.
12339 2002-02-07 Akim Demaille <akim@epita.fr>

12347 case/esac, some shells don't support it.
12348 Reported by Zack Weinberg.
12349 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
12351 2002-02-06 Akim Demaille <akim@epita.fr>
12353 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
12354 sure not to introduce newlines in at_groups.
12355 * lib/autotest/Makefile.am (autotest.m4f): Typo.

12365 Describe HP-UX cc bug workaround more accurately.

12368 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
12369 cross-compilers, too. This undoes some of the most recent change
12372 2002-02-05 Akim Demaille <akim@epita.fr>
12374 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
12375 to make sure they are up to date when `check' is run.
12377 2002-02-05 Akim Demaille <akim@epita.fr>

12391 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
12392 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
12394 2002-02-05 Akim Demaille <akim@epita.fr>
12396 * bin/autom4te.in (&parse_args): Implement `frozen files are
12397 optional are the sum of the previous files on the command line'.
12398 Also, pass `--reload-state=' on them, so...
12399 (handle_m4): don't.
12400 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12401 (M4sh): Rely on M4sugar.
12402 (Autotest, M4sh, M4sugar): Use frozen files.
12404 2002-01-31 Akim Demaille <akim@epita.fr>
12406 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
12407 * doc/autoconf.texi (Initializing configure): Adjust.
12409 2002-01-30 Akim Demaille <akim@epita.fr>
12411 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
12412 alphanumeric to `-' instead of `_'.
12414 2002-01-30 Akim Demaille <akim@epita.fr>
12416 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
12417 for plain code, the other for cross-compilation code. The latter
12418 is now run with GCC only.
12419 * doc/autoconf.texi (Compilers and Preprocessors): New.

12423 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
12425 * doc/autoconf.texi (Initializing configure): Explain how to
12426 change AC_INIT default values.
12428 2002-01-29 Akim Demaille <akim@epita.fr>
12430 * tests/torture.at (Configuring subdirectories): Use configure.in,
12431 so that aclocal 1.4 works.
12432 Reported by Alexandre Duret-Lutz and Larry Schmitt.
12434 2002-01-28 Akim Demaille <akim@epita.fr>
12436 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
12439 2002-01-28 Akim Demaille <akim@epita.fr>
12441 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12442 AUTOTEST_PATH *after* it was set.
12443 Don't put `.' in the PATH: the user should be precise and `./' if
12444 needed. In addition, given that the test suite does some `cd', if
12445 `.' is in the path, the `tested programs' sections will report
12446 programs found in the test suite's directory, while during the
12447 tests (performed in their own directory), these programs are no
12448 longer visible. In other words, the results is confusing and
12450 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

12471 Update from masters.
12473 2002-01-24 Akim Demaille <akim@epita.fr>
12475 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.

12484 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
12485 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.

12494 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
12495 message on invalid options.
12496 * bin/autom4te.in (parse_args): Don't use
12497 Autoconf::General::getopt with non valid options.

12515 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
12516 package.m4, since is really depends upon configure.ac, not
12518 * doc/autoconf.texi (testsuite Scripts): Adjust.
12519 * tests/Makefile.am (package.m4): New.
12520 EXTRA_DIST it since its a source.
12522 2002-01-06 Akim Demaille <akim@epita.fr>
12524 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
12525 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12526 and PACKAGE_BUGREPORT from here...
12527 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12529 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
12530 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
12531 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.

12541 * doc/autoconf.texi (Output): Improved wording regarding use of
12545 2001-12-18 Kevin Ryde <user42@zip.com.au>
12547 * doc/autoconf.texi (Function Portability): Add notes on sscanf
12548 sometimes needing writable input.
12550 2001-12-17 Jim Meyering <meyering@lucent.com>
12552 * doc/autoconf.texi (New Macros): Tweak wording.
12554 2001-12-14 Akim Demaille <akim@epita.fr>
12556 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
12557 trailing files, don't apply `-rf' to files which might not be
12558 created by configure (core, core.*, and *.core), but just `rm -f'.
12559 Suggested by Jonathan Kamens.
12561 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
12563 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
12565 2001-12-14 Akim Demaille <akim@epita.fr>
12567 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
12569 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
12571 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
12572 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
12573 abs_srcdir, top_srcpath to abs_top_srcdir.
12574 (_AC_OUTPUT_FILES): Adjust.
12575 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
12576 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
12577 * tests/wrappl.in, tests/wrapsh.in: Adjust.
12579 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
12581 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
12582 C/Fortran linking on HP/UX, by extracting the Fortran library
12583 search path from the LPATH line in the $F77 -v output.
12585 2001-12-12 Kevin Ryde <user42@zip.com.au>
12587 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
12588 forbidden file descriptors table.
12590 2001-11-26 Akim Demaille <akim@epita.fr>
12592 * bin/autoscan.in (%c_keywords): Build it at top level.
12593 Map to 1 in order to simplify its uses.
12595 2001-11-26 Akim Demaille <akim@epita.fr>
12597 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
12598 Remove $filepath, useless.
12599 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
12600 variables, they are really part of the tokens.
12601 Split the input line on spaces and then look for tokens.
12602 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
12603 because of `lex$U.$(OBJEXT)'.
12604 (&scan_files): Use "@list" instead of join.
12605 * doc/Makefile.am (CLEANFILES): Add *.fns.
12607 2001-11-26 Akim Demaille <akim@epita.fr>
12609 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
12610 Remove, replaced by...
12611 * tests/wrappl.in: Be common for all the Perl executables.
12612 In particular autoscan and autoheader want -I.
12613 * configure.ac: Adjust.
12614 * lib/autoscan/headers: errno.h is portable.
12616 2001-11-26 Akim Demaille <akim@epita.fr>
12618 * bin/autoscan.in (used): New.
12621 2001-11-26 Akim Demaille <akim@epita.fr>
12623 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
12625 (&scan_sh_file): Remove a duplicate pattern.
12626 (&check_configure_ac): Use long options.
12627 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
12629 2001-11-26 Akim Demaille <akim@epita.fr>
12631 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
12632 Before, having a line containing the opening of a multi line
12633 comment made the whole line be ignored.
12635 2001-11-26 Akim Demaille <akim@epita.fr>
12637 * doc/autoconf.texi (Using an Autotest Test Suite): New.
12638 (testsuite Scripts): Be one of its subsection.
12639 (Autotest Logs): New.
12641 2001-11-26 Akim Demaille <akim@epita.fr>
12643 Test groups are now run two directories deeper.
12645 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
12646 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
12648 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
12649 top_srcdir, builddir and top_builddir.
12650 Use `at_*dir' relatively to the directory containing the
12651 suite, use `*dir' when relatively to the current group dir.
12653 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
12655 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
12656 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
12657 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
12660 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12662 * doc/autoconf.texi (Using System Type): Add an example of `case
12663 $host' usage so people quit using `case $target' everywhere.
12665 2001-11-22 Akim Demaille <akim@epita.fr>
12667 * doc/autoconf.texi (Installation Directory Variables): Englishoes
12668 spotted by Jim Meyering.
12670 2001-11-16 Paul Eggert <eggert@twinsun.com>
12672 This patch implements a `long double' suggestion by Oliver Kiddle.
12674 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12675 static, to catch errors if the value isn't known at compile-time
12676 and the compiler supports dynamic arrays. Change its name from
12677 `_array_' to `test_array' to avoid potential name clashes.
12678 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12679 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12680 better than double. Catch a bug in GCC 2.95.2 x86.
12681 * doc/autoconf.texi (C Compiler): Document the above.
12684 2001-11-13 Akim Demaille <akim@epita.fr>
12686 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
12688 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
12690 2001-11-13 Akim Demaille <akim@epita.fr>
12692 * lib/autotest/general.m4 (AT_INIT): After having run the test
12693 group, go back to the initial directory, not to at_suite_dir.
12695 2001-11-13 Akim Demaille <akim@epita.fr>
12697 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12698 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12699 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12701 (AT_CHECK_CONFIGURE): Use absolute paths.
12702 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12703 The problem is still the old one: there is no means in M4 (that I
12704 know about) to create a defining macro, because there is no means
12705 to create `$1' etc., therefore, the defining macro ``swallows''
12706 all the arguments meant to the defined macro.
12708 2001-11-13 Akim Demaille <akim@epita.fr>
12710 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
12711 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
12713 * tests/aclocal.m4: Remove, as it is no longer used.
12715 2001-11-13 Akim Demaille <akim@epita.fr>
12717 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12718 variable names when referring to a single test group, or to
12719 `suite' when referring to the whole test suite.
12720 `at_last_test' is removed: m4 compute at_format itself.
12721 (at_stdout, at_stder1, at_stderr): New variables.
12722 (AT_CHECK): Use them.
12724 2001-11-13 Akim Demaille <akim@epita.fr>
12726 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12728 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12729 Do it as soon as a test fails, don't wait till the end of the test
12731 Don't remove $as_me.[0-9]*, since these files no longer exist.
12733 2001-11-13 Akim Demaille <akim@epita.fr>
12735 * tests/tools.at: Use absolute paths, since we are no longer run
12738 2001-11-13 Akim Demaille <akim@epita.fr>
12740 Now that tests are running in their own private dir, there is no
12741 need to list the files to remove at the end of tests groups.
12743 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12744 (AT_data_files, at_data_files): Remove.
12745 (AT_CLEANUP, AT_DATA): Simplify.
12747 Remove the group dir if !debug && !failed.
12748 * tests/atspecific.m4: Adjust.
12750 2001-11-13 Akim Demaille <akim@epita.fr>
12752 Start a new layout for Autotest: `testsuite' creates
12753 `testsuite.dir' in which the at-check-line etc. files are to be
12754 found, and `testsuite.dir/003' where the test group 3 is run.
12756 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12757 at_check_line_file, at_format, at_test_normalized, at_group_dir
12759 Create the directories.
12760 Use absolute paths for at- files.
12761 (AT_CHECK): Adjust.
12763 2001-11-11 Michael Matz <matz@kde.org>
12765 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
12767 (m4_car): Properly quote arguments.
12769 2001-11-13 Akim Demaille <akim@epita.fr>
12771 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
12772 with stricter rules on LIBOBJS.
12774 2001-11-12 Paul Eggert <eggert@twinsun.com>
12776 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
12777 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
12780 2001-11-12 Akim Demaille <akim@epita.fr>
12782 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
12784 2001-11-12 Akim Demaille <akim@epita.fr>
12786 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
12787 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
12788 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12789 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
12790 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
12791 specify to what the macro should be defined (typically to 1).
12793 2001-11-12 Akim Demaille <akim@epita.fr>
12795 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
12798 2001-11-12 Akim Demaille <akim@epita.fr>
12800 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12801 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
12802 definition used by Automake where LEX is +/- "${missing} lex" and
12803 `missing' itself contains variables.
12805 2001-11-12 Akim Demaille <akim@epita.fr>
12807 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
12808 Now that M4sh pushes BODY, the comments were output at the end of
12811 2001-11-08 Akim Demaille <akim@epita.fr>
12813 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
12814 that we can trace macros from aclocal.m4.
12815 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
12816 obsoleted, and redirect to the former anyway.
12817 Reported by Ralf Corsepius.
12819 2001-11-08 Akim Demaille <akim@epita.fr>
12821 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
12822 processed only if present.
12823 * tests/torture.at (Configuring subdirectories): Use autoreconf
12824 instead of successive calls to autoconf.
12825 Add a nonexistent subdirectory to exercise the patch above.
12826 Reported by Ralf Corsepius.
12828 2001-11-08 Kevin Ryde <user42@zip.com.au>
12830 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
12831 doesn't accept .S files.
12833 2001-11-07 Akim Demaille <akim@epita.fr>
12835 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
12836 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
12837 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
12838 * bin/autom4te.in (warn_forbidden): New.
12839 (handle_output): Use it.
12840 Read m4_pattern_forbid with messages.
12842 2001-11-05 Akim Demaille <akim@epita.fr>
12844 * bin/autom4te.in (--normalize): Remove.
12845 * lib/autom4te.in: Adjust.
12847 2001-11-05 Akim Demaille <akim@epita.fr>
12849 * tests/Makefile.am (testsuite): Rename this target as...
12850 ($(TESTSUITE)): this.
12853 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
12855 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
12856 the --prefix option, also remove it's argument.
12858 2001-11-05 Akim Demaille <akim@epita.fr>
12860 * doc/autoconf.texi (testsuite Invocation): Update.
12861 (Writing testsuite.at): Update.
12863 2001-11-03 Akim Demaille <akim@epita.fr>
12865 * doc/autoconf.texi: s/@code/@command/ where appropriate.
12867 2001-11-03 Akim Demaille <akim@epita.fr>
12869 * lib/Autom4te/General.pm: (&catfile, &canonfile)
12870 (&file_name_is_absolute): New, wrappers around routines from
12872 Use and export them.
12873 (&find_configure_ac): Optionally take a directory where to look at.
12874 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
12876 Default @ARGV to `.', not find_configure_ac.
12877 (&autoreconf): Argument is a directory.
12878 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
12879 * doc/autoconf.texi (autoreconf Invocation): Update.
12881 2001-11-03 Akim Demaille <akim@epita.fr>
12883 * lib/Autom4te/General.pm (@export_vars, @export_subs)
12884 (@export_forward_subs): New.
12885 Add basename, dirname, and fileparse.
12887 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
12888 Don't look for aclocal flags if we already know aclocal is not
12890 Move aclocal.m4t only if it exists.
12891 Reported by Ezra Peisach.
12893 2001-11-03 Akim Demaille <akim@epita.fr>
12895 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
12896 passed on command line, defaulting to ./configure.ac if present.
12897 (&maybe_autoreconf, File::Find): Remove, unused.
12898 (&autoreconf): If autoconf is not used, don't try to trace.
12900 2001-11-02 Akim Demaille <akim@epita.fr>
12902 * configure.ac: Bump to 2.52g.
12904 2001-11-02 Akim Demaille <akim@epita.fr>
12908 2001-11-02 Akim Demaille <akim@epita.fr>
12910 * config/config.guess, config/config.sub, doc/standards.texi:
12911 * config/lispdir.m4: Update from masters.
12912 * configure.ac: Bump to 2.52f.
12914 2001-11-02 Akim Demaille <akim@epita.fr>
12916 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
12917 Don't run aclocal when aclocal.m4 is not from aclocal.
12919 Don't run libtoolize and gettextize if --install is not given.
12921 2001-11-01 Paul Eggert <eggert@twinsun.com>
12923 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
12924 be invoked before _AS_LINENO_PREPARE.
12925 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
12926 than character ranges.
12928 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
12929 invoking AS_BASENAME. Set the locale variables to 'C' if
12930 possible, as POSIX requires this to get the traditional
12932 * doc/autoconf.texi (Special Shell Variables): Describe the above.
12934 2001-10-31 Paul Eggert <eggert@twinsun.com>
12936 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
12937 with {}, as that triggers a bug in Bash 2.05.
12939 (_AS_LINENO_PREPARE): Use Sed rather than
12940 Awk. Fix the sed prepass to work even if there are multiple
12941 instances of $LINENO on the same line. Do not substitute for
12942 other variables like $LINENOT. Do not check file dates; such a
12943 check is unreliable on sufficiently fast machines, and removing
12944 the check makes the code simpler and more reliable. Check for
12945 output and chmod failures.
12947 * doc/autoconf.texi (Special Shell Variables): Document
12950 2001-10-31 Akim Demaille <akim@epita.fr>

12957 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
12958 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be

12965 lib/Autom4te/Struct.pm:

12972 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.

12993 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
12994 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
12995 POSIX decided to standardize on the int flavor of strerror_r.
12996 Always do char* test, as there's no reason not to.
12997 Assign to a char* var, to catch strerror_r that returns int*.
12999 * doc/autoconf.texi (Particular Functions):

13029 (&parse_args): Use -I, --include instead of the old Autoconf
13031 ($localdir, $autoconf_dir): Remove.

13056 configure.ac being studied.
13058 2001-10-18 Paul Eggert <eggert@twinsun.com>
13060 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned

13067 (AS_BASENAME): Use 'basename' if that works; then try 'expr';

13071 contains white space.
13072 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

13129 2001-10-08 Akim Demaille <akim@epita.fr>

13448 * tests/Makefile.am (package.m4): Remove.
13450 2001-09-22 Akim Demaille <akim@epita.fr>
13452 Rely on `$LINENO' when possible instead of `__oline__'.
13454 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
13455 `$LINENO' support replacement when not supported.
13456 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
13457 them explicitly to be sure they are not output before this section

13471 2001-09-21 Akim Demaille <akim@epita.fr>
13473 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
13474 Suggested by Jim Meyering.

13492 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

13494 be used instead of ':'.
13495 * lib/autotest/general.m4: Replace occurrences of ':' in
13496 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
13498 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

13501 arguments. Fixed a typo.
13503 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13505 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
13506 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
13508 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13510 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

13517 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13519 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
13520 already have $file). Set output files to binary mode (helps avoid
13521 CR issues on DOSish systems).
13523 2001-09-19 Akim Demaille <akim@epita.fr>
13525 * lib/autotest/general.m4: Englishoes.
13526 From Tim Van Holder and Alexey Mahotkin.
13528 2001-09-18 Paul Eggert <eggert@twinsun.com>
13530 * doc/autoconf.texi (Common Shell Constructs): New node,
13531 documenting AS_DIRNAME.
13532 (Limitations of Usual Tools): Refer to it when discussing dirname.
13533 Also, update discussion of POSIX standard to reflect latest draft.
13535 * lib/autoconf/c.m4:
13536 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13538 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13539 Do not pass a first argument with leading '-'
13540 to expr, by parenthesizing initial integers that might be negative.
13542 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
13543 now merely checks whether it is an error to pass an argument
13546 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13547 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
13548 whether it is a (compile-time) error to pass an argument to
13549 getpgrp. This simpler test supports the revised documentation,
13550 and is all that AC_FUNC_GETPGRP's users really need.
13552 2001-09-18 Akim Demaille <akim@epita.fr>
13554 * doc/autoconf.texi (Limitations of Make) <$<>: New.

13564 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
13566 Add test for AS_BASENAME.
13567 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13568 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13569 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13570 * tests/base.at: Fixed the expected responses. The old ones were
13572 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13573 the documentation claims it should (and how it behaved in 2.13).
13575 2001-09-18 Akim Demaille <akim@epita.fr>
13577 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13578 the AC_CONFIG_COMMANDS invocation.
13579 This also solves the name clash problems.
13580 Don't set the package's ID.
13581 * lib/m4sugar/Makefile.am (version.m4): Revamp.
13582 No longer to be shipped.
13583 (version.in): Remove.
13584 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
13585 * lib/autoconf/status.m4: Adjust.
13586 Use `m4_PACKAGE_STRING'.
13587 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13588 the only optional argument is the name of the test suite.
13589 Expect `package.m4' to define the package signature.
13590 * lib/autom4te.in (Autotest): Add `package.m4?'.
13591 * tests/Makefile.am (package.m4): New.
13592 * tests/suite.at: ifnames is a victim.
13594 2001-09-18 Akim Demaille <akim@epita.fr>
13596 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
13597 AC_LIBSOURCE, AC_CONFIG_FILES.
13598 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
13599 program version string doesn't match the package's.
13600 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

13611 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13612 Always include <stdio.h> and <stdlib.h>. Evaluate
13613 the expression in an extra function before these includes. Call
13614 fprintf "%d" only after ensuring the argument is of type 'int'.
13615 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13617 2001-09-17 Paul Eggert <eggert@twinsun.com>
13619 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13620 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13621 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13622 when they don't exist.
13624 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13625 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13628 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13629 version with the version used by fileutils 4.1, except use
13630 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
13633 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
13635 2001-09-13 Akim Demaille <akim@epita.fr>

13675 * lib/autotest/general.m4 (AT_INIT): Create and remove
13676 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
13677 test suites can cohabit.
13679 2001-09-13 Akim Demaille <akim@epita.fr>
13681 * tests/mktests.sh: Don't output banners for empty test files.

13733 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

13736 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

13787 2001-09-05 Akim Demaille <akim@epita.fr>
13789 Be ready to handle filenames as stupid as `dnl.at', for if even
13790 the maintainer is dumb enough to do that...
13792 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
13793 excellence in M4 quotation: consider `__file__' is active.
13795 And BTW, when invoking m4, pass the --include in the right order:

13874 2001-08-31 Akim Demaille <akim@epita.fr>
13876 * man/Makefile.am (.x.1): We really have to pass
13877 autom4te_perllibdir.

13881 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
13882 debug scripts, in particular passing explicitly listed tests to

13887 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
13888 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
13889 Use directly autom4te, not autoconf.

13931 Drop AC_MACRODIR dead for real.
13932 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
13933 `autoheader: `config.hin' is created'.
13934 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
13936 2001-08-31 Akim Demaille <akim@epita.fr>

13944 Map --localdir, --autoconf-dir onto it.
13945 Forward autom4te's options instead of interpreting them.
13946 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
13947 There is no such envvar since the inception of autom4te.cfg.

13970 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

13973 find the executables for it.

13975 * tests/atlocal.in: Remove all the obscure envvar manipulations.
13977 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
13978 indeed related to running the test suite, while passing

13980 Autoconf executables. So don't do that, leave it to...

13982 * tests/autoscan: New.
13983 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14000 Suggested by Paul Eggert.
14002 2001-08-29 Akim Demaille <akim@epita.fr>

14409 * doc/autoconf.texi: Work around Texinfo buglets.
14410 (Transformation Rules): One example is enough, users are expected

14469 autom4te.cache (it's a directory, not a file.
14470 * Makefile.am: Ditto (but maintainer-clean-local).
14472 2001-08-15 Akim Demaille <akim@epita.fr>
14474 * bin/autom4te.in (@m4_warning): New.
14475 (&handle_m4): Use it.
14476 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
14477 warnings are issued at each run.
14478 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
14479 is in the src tree.
14481 2001-08-15 Akim Demaille <akim@epita.fr>
14483 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
14484 don't waste time running `autoupdate --version' works.

14548 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
14549 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
14550 * doc/autoconf.texi (C Compiler Characteristics): Update

14556 magic values from an object file when cross-compiling.
14557 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
14559 2001-08-10 Akim Demaille <akim@epita.fr>
14561 * bin/autom4te.in (&handle_output): Don't use `grep' with side
14563 Suggested by Russ Allbery.
14565 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14567 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
14568 current $prefix to the sub-configures.
14570 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14572 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
14573 extension (needed on BeOS). Reported by Guido van Rossum.
14575 2001-08-09 Akim Demaille <akim@epita.fr>
14577 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14579 2001-08-07 Akim Demaille <akim@epita.fr>
14581 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14583 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14584 No need to remove the files before and after the each test, before
14585 each test and at the end of the suite is enough.
14586 Display only the children `times', not the shell's.
14587 If the test failed or was skipped, at-times is not available.
14589 2001-08-07 Akim Demaille <akim@epita.fr>
14591 Always produce testsuite.log, including when there are no
14592 failures. This helps getting information on skipped tests, and
14593 duration of the tests. Err, implement the latter btw.
14595 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14596 Dump information on the first run of each test.
14597 (AT_CLEANUP): Create `at-times' containing the duration of the
14600 2001-08-07 Akim Demaille <akim@epita.fr>
14602 The use of `dumpstat' revealed that `len' was used although it
14603 should not. m4_text_wrap was using it, but in the Autoconf world
14604 where it is legal. Hence (i) test M4sh in its own world, not
14605 Autoconf's, and (ii), ahem, fix the bug :)
14607 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14608 does not like `' instead of [].
14609 (AT_INIT): Forbid `^_?AT_'.
14610 And don't output such tokens.
14611 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
14612 `script.as', and `autom4te.cache'.
14613 Remove `empty' and `macro' which are no longer used.
14614 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
14615 * tests/m4sugar.at: Use it.
14616 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
14618 2001-08-07 Akim Demaille <akim@epita.fr>
14620 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
14622 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
14624 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
14626 2001-08-04 Akim Demaille <akim@epita.fr>
14628 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
14629 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
14631 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
14632 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
14633 (AC_F77_MAIN): Likewise.
14635 2001-08-04 Akim Demaille <akim@epita.fr>
14637 Don't rely on M4sugar outputting the patterns in files, since we
14638 might process the output _without_ running m4, hence without these
14641 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
14642 * bin/autom4te.in (@Request::includes): Remove, unused.
14643 (@Request::source): Rename as...
14644 (@Request::input): this.
14645 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
14646 (&handle_output): Fetch the patterns from the traces.
14647 `$forbidden' and `$allowed' are constant: use m//o.
14648 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
14649 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
14651 2001-08-04 Akim Demaille <akim@epita.fr>
14653 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
14654 autoconf', i.e., in addition to caching traces, cache the output.
14656 * bin/autom4te.in (Request::cache): Rename as...
14657 (Request::id): this.
14658 ($cache, $icache, $tcache, $ocache): New.
14659 (&handle_m4): Save M4 output in the cache instead of $tmp.
14660 (&handle_output): Adjust.
14661 (&up_to_date_p): Check that the output cache is up to date too.
14662 (top level): Run `&handle_m4' iff force or the cache is invalid.
14663 Run `&handle_output' if the output cache is more recent.
14665 2001-08-04 Akim Demaille <akim@epita.fr>
14667 * bin/autom4te.in ($force): New.
14668 (&parse_args, &print_usage): -f, --force is a new option.
14669 (&handle_output): CPP directives might have spaces after `#'.
14670 (&parse_args): The first file only can be frozen.
14672 2001-08-04 Akim Demaille <akim@epita.fr>
14674 Don't let autom4te compute the `include' traces several times:
14675 first check that the trace cache file is up to date, and then
14676 compare its timestamp with that of the output.
14678 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
14679 the preamble. Don't require 5.005 as Autom4te::General does it,
14680 and better yet (use `use', not `require'!).
14681 * lib/Autom4te/Struct.pm: Rename the last occurrences of
14682 Class::Struct as Autom4te::Struct.
14683 * lib/Autom4te/General.pm (File::stat): Use it.
14684 (&mtime): New, export it.
14685 * bin/autom4te.in: Use it.
14686 Declare `$req' is invalid if it is outdated.
14687 Don't declare it valid before saving it if something went wrong.
14689 2001-08-04 Akim Demaille <akim@epita.fr>

14692 must be proposed to the users.
14694 * bin/autom4te.in (@required_trace): Remove.
14696 (&parse_args, &print_usage): -p, --preselect is a new option.
14697 (&up_to_date_p): Adjust.

14737 (m4_divert_pop): Dump the whole diversion stack when a diversion
14739 * bin/autom4te.in (&handle_output): Remember of the first
14740 occurrence of a possibly undefined macro, not the last.

14742 the appear in the output.
14743 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
14744 * tests/tools.at (autoconf: forbidden tokens, basic)
14745 (autoconf: forbidden tokens, exceptions): No longer sort
14746 autoconf's stderr, as it is now deterministic.
14747 Check that `dnl' is caught.

14769 `END', as `Autom4te::General::END' will be triggered.
14770 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
14771 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
