394 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
395 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former

399 (AC_CHECK_SIZEOF): Allow argument to be a variable.
400 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

511 shells.
513 2007-02-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
514 and Paul Eggert <eggert@cs.ucla.edu>
516 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix quoting
517 errors introduced in last change.
519 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
521 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
522 an actual carriage return. Use "ac_cr" to contain the actual
523 carriage return.
524 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
525 with traditional Awk and begin.
526 * tests/torture.at (Limitations of Builtins): Document the problem
527 with Bash 2.03 printf.
528 (Substitute and define special characters):
529 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
531 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
533 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
534 input from /dev/null in awk test, so even Solaris /usr/bin/awk
535 will not wait for input with a script containing only a BEGIN
536 rule.
538 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
540 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version
541 requirements.
542 * README: Likewise.
544 2007-02-02 Eric Blake <ebb9@byu.net>
546 * NEWS: Update copyright.
548 * m4/m4.m4 (AC_PROG_GNU_M4): Reject M4 1.4 through 1.4.4 as
549 broken.
550 * configure.ac: Update error message.
551 * NEWS: Note that M4 1.4.5 or later is now a hard dependency.

558 * THANKS (people): Update.
560 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
562 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
563 latest version.
564 (Shell Substitutions): Note problems with @{var:=value} etc.
565 Add a new section for problems with @{#var} etc. Problem noted
566 by Ralf Wildenhues. See:

569 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
571 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
572 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
573 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
574 substitution will still be done by the special code.
575 Report by Jim Meyering.
577 * doc/autoconf.texi (File System Conventions): Mention that
578 $PATH_SEPARATOR is for the build system only.
579 Report by Keith Marshall.

584 all non-NUL characters are ok in substituted values.
585 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
586 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
587 carriage return for $AWK, needed for BSD awk.
588 * tests/torture.at (Substitute and define special characters):
589 Test all 8 bit non-NUL characters.
590 Report against Automake by Patrick Welche.
592 2007-01-15 Stepan Kasal <kasal@ucw.cz>
594 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
596 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
598 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
599 early on the reader side, drop stderr of the input to avoid
600 `broken pipe' error output; this may happen even with shell
601 builtin `echo' of some bash versions. Reports by Ian Macdonald
602 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
604 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
606 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
607 separate items of `ac_user_opts', to avoid long lines.
608 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
610 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
612 * doc/autoconf.texi: Fix some typos.
614 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
616 Fix some wording problems noted by Paolo Bonzini in:
617 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
618 * doc/autoconf.texi (Signed Overflow Examples): Give more
619 discussion about the allow_superuser_privileges example,
620 and change it a bit to make things clearer.
621 (Optimization and Wraparound): Clarify whether the compiler
622 will generate an infinite loop for the example derived from
623 Autoconf's mktime test.
624 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
625 Also, clarify unsigned multiplication overflow.
627 2007-01-04 Eric Blake <ebb9@byu.net>
629 * bin/Makefile.am (RELEASE_YEAR): New macro.
630 (edit): Use it to supply correct copyright year to scripts.
631 * bin/autoconf.as (version): Use it.
632 * bin/autoheader.in ($version): Likewise.
633 * bin/autom4te.in ($version): Likewise.
634 * bin/autoreconf.in ($version): Likewise.
635 * bin/autoscan.in ($version): Likewise.
636 * bin/autoupdate.in ($version): Likewise.
637 * bin/ifnames.in ($version): Likewise.
639 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
641 * doc/autoconf.texi (Integer Overflow): Revised based on today's
642 feedback. The most important changes document what happens when
643 you convert an out-of-range value to a signed integer type, and
644 say that (sum < a) != (b < 0) reliably detects overflow when sum =
645 a + b.
647 * doc/autoconf.texi (Integer Overflow): Greatly expand and
648 rewrite, taking notions from the recent discussion on the gcc and
649 autoconf mailing lists; please see
650 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
651 and follow the many links.
652 (Integer Overflow Basics, Signed Overflow Examples):
653 (Optimization and Wraparound, Signed Overflow Advice):
654 (Signed Integer Division): New sections.
656 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
658 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
659 preprocessor macro arguments in traced name.
660 * doc/autoconf.texi (Defining symbols): Document longstanding
661 support for AC_DEFINE-ing macros with arguments, and document
662 behavior when the same variable has multiple AC_DEFINEs.
663 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
664 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
665 macros directly, giving much shorter and simpler code.
667 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
669 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
670 space before "$ac_configure_args" to prevent a 'config.status
671 --recheck' failure if ac_configure_args doesn't contain a leading
672 space. This works around a problem with the XEmacs configure.ac,
673 which uses the (undocumented) ac_configure_args variable
674 inconsistently with Autoconf.
676 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
678 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
679 Include <limits.h>, and use its INT_MAX to rewrite the
680 j loop so that it does not overflow 'int'. Problem reported by
681 Ralf Wildenhues in
682 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
683 Play it safe by shifting left by 1 rather than multiplying by 2,
684 as GCC is less likely to optimize this away when the value
685 is signed (when it assumes overflow leads to undefined behavior).
686 Also, don't assume time_t uses two's complement.
688 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
690 * tests/torture.at (Substitute a 2000-byte string): Avoid using
691 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
692 dumps core on it. Report by Tim Rice.
694 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
696 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
697 --disable-option-checking to --help output even when
698 AC_PRESERVE_HELP_ORDER is not used.
699 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
700 --with argument, rather than argument with [-.] replaced by
701 underscores.
702 * NEWS: Fix typo in previous change; the news was in the
703 wrong section.
705 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
707 * NEWS: Warnings are now generated by default for unknown
708 --enable-* and --with-* options.
709 * doc/autoconf.texi (Option Checking): Renamed from
710 (Configure Option Checking). Tighten up the wording a bit.
711 (External Software, Package Options): Cross-reference to Option
712 Checking, and use this to shorten our section.
713 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
714 "$x" to test "x$foo" != x.
715 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
716 Don't warn if $enable_option_checking is "no".
717 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
718 ac_unrecognized_opts to the empty string.
719 Don't echo the unrecognized opts, as this might mishandle
720 backslashes or leading -.
721 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
722 usage next to the other --disable-FEATURE options in the
723 help string.
725 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
727 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
728 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
729 Print warning for unrecognized --with and --enable options
730 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
731 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
732 Disable option checking when subdirs are configured.
733 (AC_OUTPUT): If warnings are enabled, print warning about
734 unrecognized --with and --enable options at the end of
735 the configure output (as well as at the beginning).
736 * doc/autoconf.texi (Option Checking): New node.
737 Document new option warning functionality.
739 2006-12-16 Eric Blake <ebb9@byu.net>
741 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
742 * NEWS: Start news for current version.
744 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
746 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
747 Define HAVE_GETMNTENT to 1, not to the empty string.
748 Problem originally reported by Jochen Friedrich in
749 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
751 This change prompted by a problem report by Andrey Simonenko in
752 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
753 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
754 object-like macros only, in the traditional portable character
755 set.
756 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
757 Warn about attempts to define things that are not identifiers.
758 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
759 awful hack that AC_DEFINEd macro names containing parentheses.
761 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
763 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
764 too drastic, even if Texinfo in theory requires it for info mode.
766 (config.status Invocation): Renamed back from Recreating a
767 Configuration).
768 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
769 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
771 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
773 * NEWS: Version 2.61a.
775 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
776 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
778 * NEWS: Document changes with echo and printf, and the lack
779 of limits on the total size of multi-line values of substituted
780 variables, and the AC_FUNC_FSEEKO fix.
782 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
784 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
785 Writing configure.ac.
786 (Autoconf Input Layout): Renamed from configure.ac Layout.
787 (Recreating a Configuration): Renamed from config.status Invocation.
788 (Obsolete Recreation): Renamed from Obsolete config.status Use.
789 (acconfig Header): Renamed from acconfig.h.
790 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
791 (Writing Testsuites): Renamed from Writing testsuite.at.
792 (Autom4te Cache): Renamed from autom4te.cache.
794 * BUGS: Remove mention of VPATH problem, since it's now documented
795 not to be a bug in the Autoconf build procedure itself, but rather
796 a problem with the proprietary `make' programs.
798 * doc/autoconf.texi (Build Directories): Add a cross reference
799 to VPATH and Make.
801 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
802 * doc/standards.texi: Sync from gnulib.
804 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
805 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
806 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
807 generated automatically.
809 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
811 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
812 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
813 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
815 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
817 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
818 `CEOF$ac_eof' special marker, the awk script cannot contain a
819 line matching `^CEOF', so this is not needed any more.
820 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
821 special marker in the test.
823 2006-12-06 Stepan Kasal <kasal@ucw.cz>
825 * tests/tools.at (autom4te preselections): Use `find -newer';
826 remove one of the sleeps.
828 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
829 more readable, using ...
830 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
832 * doc/autoconf.texi (autoheader Invocation): Do not double-
833 quote the parameter of `AH_BOTTOM' in the example.
835 2006-12-05 Stepan Kasal <kasal@ucw.cz>
837 * doc/autoconf.texi (Configuration Headers): Remove the
838 example with multiple input files.
839 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
840 multiple input files.
842 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
844 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
845 creating the awk substitution script, handle one input line at a
846 time, so that the maximum length of a substituted (multi-line)
847 value is not limited by the size of the sed pattern space.
848 The trade-off is a slightly repetitive sed script.
849 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
850 can only have up to 7 characters, due to Solaris 10 /bin/sed.
851 * tests/torture.at (Substitute a 2000-byte string): Increase the
852 test with several long lines, they should not be caught by sed
853 limits any more.
855 * tests/tools.at (autom4te preselections): New test, to flag
856 entries missing from autom4te.cfg.
857 Report by David Byron <dbyron@hheld.com>.
859 * tests/torture.at (Substitute a 2000-byte string): Actually use
860 AC_PROG_AWK, so the last change works as intended.
861 (Substitute and define special characters): Likewise.
862 (Substitute a newline): Likewise.
864 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
865 instead of `awk' consistently.
866 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
867 * tests/torture.at (Torturing config.status): Test both the
868 result of AC_PROG_AWK and plain awk.
869 (Substitute a 2000-byte string): Likewise.
870 (Substitute and define special characters): Likewise.
871 (Substitute a newline): Likewise.
873 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
875 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
876 can be assigned to a function pointer. Problem reported by
877 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
878 part of a patch by Ralf Wildenhues in that same bug report.
880 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
882 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
883 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
885 2006-12-01 Eric Blake <ebb9@byu.net>
887 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
888 cross-compiling from cygwin to mingw.
889 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
890 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
891 to lib/autoconf/c.m4.
893 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
895 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
896 string for more reliable failure. Wrap the entire test that
897 causes the broken Solaris printf to dump core, in a subshell,
898 so the segmentation fault message is reliably suppressed.
899 Fix shell expansion errors by using /usr/ucb/echo always;
900 avoid an error on systems without it by another subshell.
901 Avoid m4 expansion of `$1'. Set the zeroth argument of the
902 subshell-$as_echo to `as_echo', for better error message.
904 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
906 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
907 `BASH_SOURCE' contain a newline, set them to empty, as they may
908 not be unset.
910 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
912 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
913 years and is too hard to maintain now. The last straw was
914 reported by Jerker Baeck in
915 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
916 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
917 * doc/autoconf.texi (Particular Functions): Move
918 AC_FUNC_SETVBUF_REVERSED from here...
919 (Obsolete Macros): ... to here. Say that it does nothing now.
920 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
921 Turn into (almost) a no-op.
923 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
924 (AC_C_VOLATILE):
925 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
926 These macros are obsolescent and new applications shouldn't need them.
927 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
928 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
929 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
930 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
931 (AC_FUNC_VPRINTF): Likewise.
932 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
933 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
934 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
936 * doc/autoconf.texi (Setting Output Variables): Mention that
937 @VAR1@VAR2 has unspecified behavior. Problem reported by
938 Ralf Wildenhues.
939 * NEWS: Mention this.
941 * Makefile.am: Put only a single '#' into the copyright notice,
942 so that it's also present in the output file. Standardize wording
943 in makefile copyright notices to match GNU coding standards.
944 * bin/Makefile.am: Likewise.
945 * doc/Makefile.am: Likewise.
946 * lib/Makefile.am: Likewise.
947 * lib/freeze.mk: Likewise.
948 * lib/autoconf/Makefile.am: Likewise.
949 * lib/autoscan/Makefile.am: Likewise.
950 * lib/autotest/Makefile.am: Likewise.
951 * lib/m4sugar/Makefile.am: Likewise.
952 * man/Makefile.am: Likewise.
953 * tests/Makefile.am: Likewise.
954 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
955 one-line file.
957 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
959 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
960 in the sed script that mangles the awk script: delete up to the
961 first exclamation mark only.
962 * tests/torture.at (Substitute and define special characters):
963 Test '!' too.
965 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
967 Rewrite config files generation: avoid quadratic growth in
968 the number of substituted variables by using awk instead of sed
969 for the bulk of the substitutions.
970 * NEWS: Mention this.
971 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
972 forbidden in the output (and thus input) file.
973 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
974 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
975 generate just one large awk script for substitutions,
976 eliminating much of the earlier complexity, while adding some
977 new complexity. Only expand the substitution templates at
978 configure time, for smaller configure script size. If
979 _AC_SUBST_FILES are used, test 'awk' for working getline support
980 at config.status time. If absent, interpolate through the
981 shell. The awk script was written with much help
982 from Paolo Bonzini and Paul Eggert.
983 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
984 (_AC_SED_FRAG_NUM): Likewise.
985 (_AC_SUBST_CMDS): Renamed from...
986 (_AC_SED_CMDS): ...this.
987 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
988 * tests/torture.at (Substitute a 2000-byte string): Also
989 substitute a line with 1000 words, and a variable with several
990 long lines.
991 (Substitute and define special characters): Test awk special
992 characters, and put substitution input strings `@foo@' in the
993 output, to test that no recursion happens; test several other
994 combinations from Paolo Bonzini.
996 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
998 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
999 that replaced echo with AS_ECHO where this wasn't necessary.
1000 Problem reportd by Ralf Wildenhues.
1001 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
1002 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
1003 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
1005 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1007 * lib/freeze.mk (GREP): Removed, no need to initialize this.
1009 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
1011 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
1012 that traditional Awk lacks 3-arg "split". It has it.
1013 Mention that FS must be a single character, and a few other
1014 99-byte limits of traditional Awk.
1015 Mention that if (i in a) doesn't work with traditional Awk.
1017 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
1019 * tests/autotest.at (BSx641-newline in command):
1020 (BS-BS-newline in command, BSx640-newline in command):
1021 (Newline-CODE-BS-newline in command):
1022 (Single-quote-BS-newline in command):
1023 (Single-quote-newline-BS-newline in command):
1024 Use printf '%s\n' instead of echo, for portability to hosts
1025 where echo interprets backslashes. This will break on hosts
1026 that lack printf, but for now let's assume all such hosts
1027 are dead (if not, we should get reports of test failures).
1029 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1031 'echo' has some portability problems, when given a first argument
1032 with a leading '-', or when given any argument containing '\'.
1033 Avoid using 'echo' in these cases.
1034 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
1035 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.

1037 * lib/autotest/general.m4 (AT_INIT): Likewise.
1038 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
1039 argument might be unportable.

1058 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
1059 * bin/autoconf.as: Redo verbose flag implementation, as the old
1060 scheme wouldn't work with AS_ECHO.
1061 * lib/autotest/general.m4 (AT_INIT): Likewise.
1062 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
1063 Don't use ECHO_T, since ECHO_N is now reliable.
1064 * lib/autotest/general.m4 (AT_INIT): Likewise.
1065 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
1066 rather than using a here-document to put the script into a file.
1067 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
1068 use AS_ECHO.
1069 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
1070 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
1071 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
1072 bug, but we might as well stop using ECHO_N and ECHO_C internally.
1073 * lib/autotest/general.m4 (AT_SETUP): Likewise.
1074 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
1075 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1076 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
1077 operand, as AS_ECHO requires. Avoid double file name expansion.
1078 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
1079 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
1080 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
1081 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
1082 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
1083 Double-quote strings that would otherwise contain M4 comments.
1084 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
1086 * configure.ac (AC_INIT): Bump to 2.61a.
1087 * NEWS: Likewise.

1094 * NEWS: Likewise.
1096 * tests/autotest.at (Macro with backslash in a test title):
1097 Comment out for now, as this tests neither fails nor passes
1098 reliably. Problem reported by Ralf Wildenhues.
1100 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
1102 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
1103 in previous change, which caused test failures.

1176 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
1177 benefit of platforms like Solaris+GCC where it is common to have a
1178 non-working g++ installation.

1192 Imported from a similar patch to gnulib by Bruno Haible.
1194 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
1196 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

1212 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
1213 and Stepan Kasal <kasal@ucw.cz>

1220 argument. Extend to check titles printed by ./micro-suite and
1221 ./micro-suite -l and the title in micro-suite.log.
1222 (Backquote in a test title,
1223 Single-quote in a test title,
1224 Double-quote in a test title): Don't expect failure anymore.
1225 (Backslash in a test title): Put a non-whitespace character after the
1226 backslash so that Bourne shells might actually see it as an escape
1227 sequence.
1228 (Brackets in a test title,
1229 Pound in a test title,
1230 Comma in a test title,
1231 Quoted Macro in a test title,
1232 Macro in a test title,

1238 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
1239 The visible effect was a stray [] in the testsuite output.
1241 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1243 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
1244 `trap ... 0' inside a function, for AIX sh.
1246 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1248 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1249 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1250 5363) simply issues a warning when dividing by zero at compile
1251 time. Problem reported by Elias Pipping.
1253 2006-10-26 Eric Blake <ebb9@byu.net>
1255 * THANKS: Update.
1256 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1257 show effect on macros that expand with commas.
1258 Reported by Joel E. Denny.
1260 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
1261 Also work with M4 1.4.8.

1285 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1286 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1287 reported by Nelson H. F. Beebe for Coreutils 6.4.
1289 * tests/tools.at (autoconf --trace: user macros): Remove test
1290 for tracing multiline macros, since m4 1.4.7a uses a different
1291 way to number lines. Problem reported by Ralf Wildenhues.
1293 2006-10-24 Stepan Kasal <kasal@ucw.cz>
1295 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1296 /dev/null since the heuristics for interactive behaviour was
1297 fixed in CVS m4.
1299 * bin/autom4te.in: With --force, always refresh the output
1300 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
1302 * bin/autoconf.as: Fix the verbose message at the end.
1304 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

1322 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
1324 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1326 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
1328 2006-10-19 Eric Blake <ebb9@byu.net>

1350 2006-10-14 Stepan Kasal <kasal@ucw.cz>
1352 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
1353 looking for special shell characters.
1354 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
1355 macro defined by AS_VAR_PUSHDEF before passing it as a
1356 parameter.
1357 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
1358 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

1363 * lib/autotest/general.m4 (AT_INIT): Quote parameters of
1364 AS_VAR_* properly.
1365 * tests/m4sh.at (AS_LITERAL_IF): New test.
1367 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1369 (Imported from Automake.)
1370 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1371 which incorrectly sets the mode of an existing destination
1372 directory. In some cases the unpatched install-sh could do the
1373 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1374 system. We hope this is rare in practice, but it's clearly worth
1375 fixing. Problem reported by Alex Unleashed in
1376 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1377 Also, don't bother to check for -m bugs unless we're using -m;
1378 suggested by Stepan Kasal.

1390 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
1391 gnu and gnits modes.
1393 Import this change from Config:
1395 2006-09-20 Ben Elliston <bje@gnu.org>

1398 Import this change from Gnulib:
1400 2006-09-16 Karl Berry <karl@gnu.org>

1415 * build-aux/texinfo.tex (\textdegree): New command.
1417 2006-08-12 Karl Berry <karl@gnu.org>

1422 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
1424 2006-10-13 Stepan Kasal <kasal@ucw.cz>
1426 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1427 added to the template can get mangled.
1429 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1431 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1432 include the default headers, and redefine obstack_chunk_alloc
1433 and obstack_chunk_free. Fixes false failure with glibc.

1437 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
1438 for backward compatibility with Libtool 1.5.22. Problem reported
1439 by Ralf Wildenhues.
1441 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1443 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
1444 AC_PROG_CC.

1447 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1449 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
1450 the NonStop platform.
1451 * doc/autoconf.texi (Posix Variants): Likewise.
1452 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1454 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1455 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1456 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1457 Use a better substitute, by inspecting the output of "ls"
1458 rather than just using ":".
1459 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1460 rather than AS_EXECUTABLE_P, since we needn't worry about
1461 non-regular files here.
1463 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1464 due to configuration hassles with this. See Tonya Underwood's report
1465 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1466 * doc/autoconf.texi (Special Shell Variables): Likewise.
1468 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1469 Stepan Kasal <kasal@ucw.cz>
1471 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
1472 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
1474 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1476 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1477 initialization which is not inherited through the environment
1478 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1479 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1481 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1483 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1484 problems with mkdir -p -m.
1486 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1488 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1489 comment about ac_cpp_err; it was incorrect, and anyway
1490 ac_cpp_err is being removed below.
1491 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1492 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1493 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1494 nobody uses it.
1495 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1496 with werror_flag and conftest.err and so forth. This is more
1497 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1498 and anyway the user shouldn't normally want to see this gorp logged.
1499 Problem reported by Ralf Wildenhues.
1500 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1501 empty, not 'no', since the rest of the code uses 'test -z'.
1503 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1505 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1506 Use a single call to AC_DO_TOKENS rather than multiple, for
1507 efficiency.
1508 (_AC_LINK_IFELSE): Test that resulting file is executable.
1509 Problem reported by mwoehlke in
1510 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1512 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1513 than creating a file to use with test -x; this is much faster.
1515 2006-10-02 Bruno Haible <bruno@clisp.org>
1517 * lib/autom4te.in (Automake-preselections): Add
1518 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1520 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1522 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1523 standard error, `experr' should be used, not `expout'.
1525 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1527 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1528 fseeko testing program twice; just use the earlier result.
1529 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1530 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1531 still doesn't let the program compile.
1532 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1533 failed.
1535 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1536 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1537 include it, without including anything else.
1538 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1539 expressions.
1540 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1542 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1544 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1545 `error.h', and include it, for a `error_at_line' prototype.
1546 Use a nonempty format string in the link test.
1547 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1548 for a declaration of wait3.
1550 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1552 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1553 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1554 can apply to constants too, and that it checks for macro defns.
1555 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1556 and simply cast the identifier to void. This handles structure
1557 values. Problem reported by Ralf Wildenhues.
1558 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1560 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1562 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
1563 structure, and function symbols.

1580 warnings (uninitialized value).
1581 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
1582 present.

1592 * lib/autoconf/fortran.m4 (AC_PROG_F77, AC_PROG_FC): Likewise.
1593 Report by Olly Betts.

1613 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
1614 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
1615 --error-output, to avoid warnings with M4 2.0.
1617 2006-09-19 Stepan Kasal <kasal@ucw.cz>
1619 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
1620 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
1621 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
1623 2006-09-15 Stepan Kasal <kasal@ucw.cz>

1626 expansion of AC_CHECK_FUNCS.
1628 2006-09-14 Stepan Kasal <kasal@ucw.cz>
1630 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
1631 mistaken comment: the path has to be relative; do not use
1632 the path at runtime.
1634 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1636 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

1644 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
1646 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
1647 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
1648 for the existence of the directory at configure-time. That's
1649 too late, anyway. Problem reported by Stefan Seefeld.
1651 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
1652 7.1.4 /usr/bin/posix/sh described by Tim Rice in
1653 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
1655 2006-09-11 Stepan Kasal <kasal@ucw.cz>
1657 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
1658 works with GNU M4 1.4.3 again; make the normalized form
1659 match the current m4 message; fix the description.
1660 * test/tools.at (autom4te cache): Adapt to the change.
1662 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
1664 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
1665 to catch glibc bug 2821
1666 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
1668 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1669 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1670 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
1671 assume C89.

1689 by Dries Kimpe.
1691 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1693 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1694 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1695 accept files with extension `.f'. For consistency, also prefer
1696 xlf over f77.
1697 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
1698 from last patch.

1719 except the first two arguments are reversed.
1720 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1721 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
1722 caches nor outputs a diagnostic. Suggested by Bruno Haible.

1732 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
1733 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
1734 programs should use their Gnulib counterparts.
1735 * doc/autoconf.texi (Particular Functions): Likewise.

1767 for the default, which the user can override.
1768 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1769 deal with LEXLIB.
1770 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1771 didn't work if some values were cached but not others. Test for
1772 broken lex libraries like native ia64-hp-hpux11.22; see
1773 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1774 work around the problem by preferring an empty LEXLIB to -lfl or
1775 -ll. Let the user set LEXLIB='' to indicate no library needed.
1777 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1778 * README: Likewise.

1873 * doc/autoconf.texi (C Compiler): Document // comments, va_copy.
1874 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
1875 64-bit preprocessor ints. Check for static initialization of
1876 long long. Remove unnecessary casts.
1878 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1880 * doc/autoconf.texi (Particular Programs): Mention that
1881 @INSTALL@ and @MKDIR_P@ may vary for different output files.
1882 Reported by Alexandre Duret-Lutz.
1884 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
1886 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
1887 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
1888 Bill Northcott in
1889 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
1891 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
1893 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
1894 pacify insanely picky compilers. Problem reported by Eric Blake.
1896 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
1897 longer supported by Sun.
1899 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
1901 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
1902 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1903 -Wundef -Werror". Problem reported by David Fang in
1904 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1905 * doc/autoconf.texi (Header Templates, Default Includes):

1907 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
1908 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

1920 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1921 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1922 this.
1924 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1926 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1927 problems with arg script text that doesn't end in newline, and
1928 with '-e a...'. Problems reported by Ralf Wildenhues.
1930 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1932 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
1933 check for libXt by a check for libX11.
1935 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1937 * doc/autoconf.texi (config.status Invocation): Adjust according
1938 to last change.
1940 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1942 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1943 --help' should mention that `--version' outputs configuration
1944 settings. Report by Bruno Haible.
1946 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1948 Fix test suite failures reported by Pierre in
1949 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1950 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1951 the compiler created a file "b.out" when it didn't create anything
1952 at all.
1953 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
1954 Discard stderr too, when invoking the test script.
1956 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
1958 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
1959 in the restoring of the werror flag.
1961 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
1963 * doc/autoconf.texi (Volatile Objects): Be even a little
1964 less skeptical about "volatile", after discussion with
1965 Bruno Haible on bug-gnulib.
1966 (Limitations of Usual Tools): Warn about sed stripping
1967 leading white space from text. From Bruno Haible.
1969 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1971 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1972 compiler complains about it, even if things works after the
1973 complaint. Problem reported by Peter O'Gorman.
1975 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1976 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1977 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1979 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1981 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1982 after -R regardless of host. Patrick Welche reports that this
1983 fixes things on NetBSD 3.99.

1991 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1993 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1994 under AC_C_VOLATILE.
1995 (Volatile Objects): Be a little less skeptical about what
1996 "volatile" means. Derived from thoughts by Ben Pfaff in
1997 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1999 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2001 * doc/autoconf.texi: Fix some typos.
2003 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2005 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2006 more globally, since the 2006-06-30 patch didn't suffice. Problem
2007 reported by Keith Marshall. Also, don't bother with builddir2,
2008 since it shouldn't be needed any more.
2010 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
2012 * doc/autoconf.texi (Generic compiler characteristics):
2013 Document AC_COMPUTE_INT. Fix wrong statements on Default
2014 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

2019 AC_COMPUTE_INT.
2021 * NEWS: Document change.
2023 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
2025 * doc/autoconf.texi (Volatile Objects): New section.
2027 * NEWS: Document previous change.
2029 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
2031 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
2032 Require that long long int be at least 64 bits wide. C99 requires
2033 this and enough programs depend on it so we should check for it.
2034 Bruno Haible reports in
2035 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
2036 that long long int is 32 bits wide with some nonstandard compilers.
2037 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
2039 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
2041 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2042 to a nonexistent file, so that we don't have to worry about
2043 a local site configuration that doesn't use /usr/local.
2044 Problem reported by Keith Marshall in
2045 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
2047 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
2049 * doc/autoconf.texi: Be more consistent about using @acronym with
2050 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
2051 quite right (it talked about "OSF/Tru64", even though the
2052 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
2053 and it even mentioned "OSF 4"!) and at this point there's little
2054 reason to talk about OSF any more, since it died in 1994.
2055 (Specific Compiler Characteristics): Simplify example of
2056 negative-size array.
2057 (File Descriptors): Reorder to make the text flow better.
2058 Remove joke about "appreciate the various levels"; I didn't get it.
2059 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
2060 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
2061 (File Descriptors, Limitations of Usual Tools):
2062 Tone down the advice against renaming or removing open files.
2063 (Limitations of Usual Tools): Add a new section, on 'rm'.
2065 2006-06-26 Stepan Kasal <kasal@ucw.cz>
2067 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
2068 -lXt in LIBS, idea from Karsten Hopp; this was due since
2069 this change:
2071 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2072 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2073 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2074 (which belong to Xt, not X itself). See Debian bug 327655.
2076 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2078 * configure.ac (AC_INIT): Bump to 2.60a.
2079 * NEWS: Update.
2081 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2083 Version 2.60.
2085 * configure.ac, NEWS: Update.
2087 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2089 * config/texinfo.tex: Sync from upstream.
2091 * bin/autom4te.in (handle_traces): Transform the `@S|@'
2092 quadrigraph correctly in traces.
2094 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
2095 Fix typos.
2097 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
2098 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
2099 not defined.
2100 * doc/autoconf.texi (Changed Directory Variables): New node,
2101 to document the whole `datarootdir' business a bit better.
2102 * NEWS: Update.
2103 * tests/torture.at (datarootdir workaround): Extend test.
2104 Prompted by report by Alexandre Julliard.
2106 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
2108 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
2109 when using default mode of IBM C 6 for AIX. Problem and two-line
2110 fix reported by Larry Jones.
2112 2006-06-22 Alexandre Julliard <julliard@winehq.org>
2114 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
2115 about literal '${datarootdir}' if a definition is found in the
2116 output file.
2118 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
2120 * NEWS: Use "M4" rather than "m4" when appropriate.
2121 Problem reported by Eric Blake.
2122 * doc/autoconf.texi: Likewise.
2123 Use @acronym around BSD, GCC, and GNU when appropriate.
2124 (Why GNU M4): Renamed from "Why GNU m4".
2125 (Redefined M4 Macros): Mention that Posix
2126 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
2127 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
2128 to int.
2130 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2132 * bin/autom4te.in (handle_output): Do not forbid the empty
2133 pattern.
2134 * tests/tools.at (autoconf: the empty token): New test.
2136 2006-06-20 Stepan Kasal <kasal@ucw.cz>
2138 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
2139 calls, so that we do not care whether they are LIFO or FIFO;
2140 in the m4_wrap, do not check which diversion is the topmost
2141 one, just check that the stack is balanced at the end.
2142 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
2143 base diversion forever--pop the previous diversion before
2144 opening the new one; consequently, remove the m4_wrap call.
2145 * lib/autotest/general.m4 (AT_INIT): Likewise.
2146 * tests/m4sugar.at: Do not use
2147 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
2149 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
2150 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2152 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
2153 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
2154 Rework example of m4wrap token-pasting trouble so that it doesn't
2155 care whether it's LIFO or FIFO.
2156 Fix some "contrary to"s that are awkward in English.
2158 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2160 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
2161 to `yes' instead of `int$1_t' if the type is found, for more
2162 consistent configure output (where $1 is the number of bits).
2163 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
2164 Suggested by Bruno Haible.
2166 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
2167 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
2168 with system headers. Report by Bruno Haible.
2170 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2172 * config/config.guess, config/config.sub: Sync from upstream.
2174 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2175 in order to avoid picking up an older installed frozen m4sh.m4f.
2176 Besides an outdated shell startup, this could have been created
2177 by an earlier M4 version with incompatible frozen file format.
2179 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2181 * README: Recommend m4 1.4.4 instead of 1.4.3..
2182 * doc/autoconf.texi: Likewise.
2183 (Special Chars in Names): Say that $(.FOO) is portable, as
2184 suggested by Stepan Kasal.
2185 (Installation Directory Variables, Build Directories):
2186 (Automatic Remaking, Subdirectories, Fortran Compiler):
2187 (Making testsuite Scripts, Defining Directories):
2188 Quote variable usages better.
2189 (Making testsuite Scripts): Add clean-local rule to makefile
2190 snippet, by Eric Blake.
2191 (Installation Directory Variables): Fix table item font.
2192 Reword slightly to clarify. Generalize advice about
2193 not using special characters to include all file-related
2194 vars, not just VPATH.
2195 (Special Chars in Variables): Warn about special characters in
2196 $(srcdir) too.
2197 (Assignments): Clarify default-value example as suggested by
2198 Ralf Wildenhues in
2199 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2200 (Special Shell Variables): Note leading ./ or ../, as suggested
2201 by Eric Blake.
2202 (Limitations of Builtins): Under cd, warn about CDPATH.
2203 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2204 Ralf Wildenhues.
2206 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2208 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2209 `@var', for texi2html.
2210 (Systemology): Some more word wrapping, for DVI output.
2211 (autom4te Invocation): The short option for `--melt' is `-M',
2212 not `-m'.
2214 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2216 * doc/autoconf.texi: More formatting and English tweaks,
2217 many suggested by Ralf Wildenhues.
2218 Reword to avoid "@code{...}'s" and the like, since it's ugly
2219 with Emacs info mode. discontents -> woes.
2220 Put a few "will"s back. time stamp -> timestamp.
2221 side-effect -> side effect.
2223 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2225 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2226 Warn about $@ not persisting. Problem reported by Julien Danjou in
2227 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2228 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2229 Mention other special chars, too.
2231 2006-06-14 Eric Blake <ebb9@byu.net>
2233 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2235 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2237 * doc/autoconf.texi: Some systematic minor improvements, as
2238 follows. Use "makefile" when talking about makefiles
2239 generally (which might be named "makefile" or "Makefile" or even
2240 "foo.mk"), "Makefile" when talking about a specific makefile
2241 called "Makefile". This unclutters the text from weird quotes
2242 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2243 values" rather than "@var{foo}s" and similar constructs containing
2244 "}s". Use "Make rules" rather than "Makefile rules". Minor
2245 English-language improvements. Change the prefix "sub-" to "sub"
2246 and "re-" to "re".
2247 Put blank lines around examples more consistently.
2248 Avoid "rather" and "very" as intensifiers.
2249 Avoid "will" as an auxiliary.
2250 (Limitations of Make): Split this node into....
2251 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2252 (Leading _ in Macro Names, Backslash-Newline-Newline):
2253 (Backslash-Newline Comments, Long Lines in Makefiles):
2254 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2255 (obj/ and Make, make -k Status, VPATH and Make):
2256 (VPATH and Double-colon, $< in Explicit Rules):
2257 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2258 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2259 New nodes, resulting from splitup of Limitations of Make.
2260 All cross-references changed. Raise the top node from
2261 a section to a chapter, and all subnodes accordingly.
2262 Redo the introductory wording to match the new organization.
2263 (Installation Directory Variables): Use an example that is
2264 closer to what Autoconf actually does. Mention that VPATH's
2265 value should not contain metacharacters or white space.
2266 (Fortran Compiler): Fix a VPATH bug in an example.
2267 (Leading _ in Macro Names): Mention that this problem is no longer
2268 of practical concern.
2269 (VPATH and Make): Reword the advice to make it clearer
2270 that Autoconf and Automake support VPATH in non-GNU make, but
2271 many packages have bugs in this area.
2272 ($< in Explicit Rules): Refer to Build Directories rather
2273 than using a (non-VPATH-safe) example.
2274 (Automatic Rule Rewriting): Mention the sort of disaster that
2275 can ensue with Solaris-style rule rewriting with VPATH.
2277 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2279 * doc/install.texi (Compilers and Options): Weaken the
2280 suggestion to use GNU make for VPATH builds.
2282 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2283 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2285 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2286 in regular expression.
2288 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2290 * doc/autoconf.texi (Installation Directory Variables):
2291 Drop extra @samp from `@table @samp' item.
2292 (Limitations of Usual Tools): Comment fix.
2293 Do not nest @samp just to point to other table items.
2294 (Writing testsuite.at) <AT_CHECK>: The second argument to
2295 `@dvar' is already @samp'ed.
2296 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2297 do not use @var in the second argument.
2299 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2301 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2302 $as_shell.exe too. Problem reported by Andreas Buening in
2303 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2305 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2307 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2308 `unused variable' compiler warning, for `-Wall -Werror'.
2309 Reported by Jaap Haitsma in
2310 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2312 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2314 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2315 case the compiler dumps core. Problem reported for
2316 OpenServer 5.0.7 by Tim Rice in
2317 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2318 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2319 Likewise.
2321 2006-06-06 Tim Rice <tim@multitalents.net>.
2323 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2324 "ERROR" only shows up in "make check" output if there is an
2325 error.
2327 2006-06-06 Eric Blake <ebb9@byu.net>
2329 * tests/tools.at (automatically allowed tokens): Fix typo.
2331 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2333 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2335 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2336 typically overflows on x86 CPUs, even though the C standard
2337 requires otherwise.
2339 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2341 * configure.ac (AC_INIT): Bump to 2.59e.
2342 * NEWS: Update.
2344 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2346 Version 2.59d.
2348 * config/texinfo.tex: Sync from upstream.
2350 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2351 seen, invoke libtoolize with `--ltdl' argument.
2352 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2353 * NEWS: Update.
2354 Suggested by Eric Blake.
2356 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2358 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2359 reported by Ralf Wildenhues.
2360 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
2362 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2364 * THANKS: Update.
2366 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2368 * doc/autoconf.texi: Modernize some of the references to Solaris.
2370 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2372 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2373 message issued by AC_REQUIRE.
2374 * tests/m4sugar.at: Check m4_require's error message.
2375 * tests/base.at: Check AC_REQUIRE's error message.
2376 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2377 to...
2378 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2379 AT_CHECK_M4.
2380 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2381 `expout' as the last parameter.
2382 * tests/tools.at: Adapt to the above change.
2384 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2386 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2387 information about race-free implementations of mkdir.
2389 2006-06-04 Eric Blake <ebb9@byu.net>
2391 * bin/autoreconf.in (help): Document M4 environment variable.
2392 * bin/autoconf.as (Usage): Likewise.
2393 * bin/autom4te.in (help): Likewise.
2394 * doc/autoconf.texi (autom4te Invocation): Likewise.
2396 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2398 * NEWS: GNU make now recommended for VPATH builds.
2399 Mention that some macros are now documented to be obsolescent.
2400 * doc/autoconf.texi:
2401 Prefer "current" to "modern" to describe
2402 currently-used (albeit perhaps old-fashioned) hosts.
2403 Mention which ancient features no longer need to be worried about.
2404 setgid -> set-group-ID
2405 setuid -> set-user-ID (these are the Posix terms)
2406 Fix some misuses of "only".
2407 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2408 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2409 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2410 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2411 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2412 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
2413 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
2414 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2415 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2416 Mention that these macros are obsolescent.
2417 (Installation Directory Variables): shall -> should
2418 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2419 Mention that it's now safe to use 3 and 4.
2420 (Limitations of Usual Tools): cp -r is now specified by Posix.
2421 Omit longwinded and obsolescent discussion of cp -f.
2422 Modernize discussion of expr, ls.
2423 (Limitations of Make): Modernize discussion of VPATH builds.
2424 Mention $? as a workaround in some cases.
2425 * doc/install.texi (Basic Installation):
2426 Mention "./configure; make; make install" first. Be more
2427 specific about why this file is generic. Remove unnecessary
2428 parens. Remove misleading "only". Remove obsolete advice
2429 about csh. Don't say "configure" takes awhile; say it
2430 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2431 and CC=c99 rather than CC=c89, as these are blessed by current
2432 Posix. Recommend GNU make if doing a VPATH build.
2434 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2436 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2437 examples involving shell prompts.
2439 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2440 and Paul Eggert <eggert@cs.ucla.edu>
2442 * doc/autoconf.texi (Here-Documents): Add details about the
2443 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2444 use "here-documents" instead of "here documents".
2446 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2448 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2450 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2452 * doc/autoconf.texi (File System Conventions): Warn about ":"
2453 anywhere in directory names.
2455 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2457 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2458 about quoting the case statement, just in case.
2459 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2460 was fixed in ksh93g; reported by Ralf Wildenhues.
2462 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2464 * doc/autoconf.texi (System Services): Do not document
2465 overriding EXEEXT via ac_cv_exeext=ext.
2466 (Particular Programs) <AC_PROG_MKDIR_P>:
2467 Document that ${MKDIR_P} understands --.
2468 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2469 comment.
2471 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2473 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2474 argument with leading hyphen. Problem reported by Paul Eggert.
2476 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2478 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2479 about quoting ac_try: quote all of it, if any of it seems suspicious.
2480 This means we don't have to worry about ${ or sed any more.
2481 Also, double-quote the case statement, to work around misuses via
2482 underquoting as reported by Ralf Wildenhues in
2483 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2484 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2485 undocumented and dangerous macro.
2486 Problem reported by Ralf Wildenhues in
2487 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2489 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2491 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2492 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2493 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2495 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2497 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2498 since evidently some packages rely on the old, broken behavior.
2499 Problem reported by Ralf Wildenhues in
2500 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2501 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2502 pre-2006-05-26 definitions, but leave in the comments that
2503 these macros are dangerous and should not be used.
2504 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2505 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2506 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2507 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2508 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2510 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2512 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2513 the use of 'tr', since this is our only use of 'tr'.
2515 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2516 and Paul Eggert <eggert@cs.ucla.edu>
2518 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2519 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2521 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2523 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2524 the output file in the `${datarootdir}' test.
2526 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2527 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2529 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2530 mention of `datarootdir' in the input file(s), but literal
2531 `${datarootdir}' in the output file, and we haven't warned yet,
2532 then warn as well: the user may have (erroneously) used
2533 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2534 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2535 * tests/torture.at (datarootdir workaround): Extend this test.
2536 * NEWS: Update.
2538 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2539 and Paul Eggert <eggert@cs.ucla.edu>
2541 * doc/autoconf.texi (autoheader Invocation): The first argument to
2542 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2543 alternatives and clear up the language a bit.
2545 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2547 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2548 ac_config_guess, ac_config_sub, ac_configure.
2549 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2550 Fix typo that prevented an unnecessary space from being removed.
2551 Problems reported by Ralf Wildenhues in:
2552 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2554 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2556 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2557 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2558 Don't use the term "thread-safe" to talk about mkdir race
2559 conditions, since the problem is more a process than a thread
2560 issue. Problem reported by Stepan Kasal in:
2561 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2562 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2563 the test for 'install' more closely. Look at MKDIR_P first.
2564 Look in the PATH, and at /opt/sfw/bin.
2565 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2566 Don't bother to try mkdir -p, since we already check mkdir --version;
2567 just look at the version number. (There's no easy way to check
2568 for race-free implementations.)
2569 * tests/tools.at (autoconf: subdirectories): Adjust to above
2570 changes, since MKDIR_P now might end in "/mkdir -p".
2572 * doc/autoconf.texi (autoheader Invocation): Mention that the
2573 first arg of AC_DEFINE_UNQUOTED must be a literal.
2574 Problem reported by Ben Pfaff in
2575 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2577 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2578 * doc/autoconf.texi (Special Chars in Variables): New section.
2579 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2580 (Installation Directory Variables): Quote $(datadir) better.
2581 (Limitations of Builtins): Describe some of eval's trickiness.
2583 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2584 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2585 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2586 in front of every arg, not just trailing args. Quote apostrophes.
2587 (_AC_EVAL_ECHO): New macro.
2588 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2589 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2590 removed.
2591 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2592 exposed by quoting of eval argument. Put the command on line line
2593 so it logs better.
2594 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2595 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2596 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2597 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2598 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2599 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2600 Use eval more safely.
2601 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2602 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2603 to be replaced.
2604 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2605 lines, exposed by quoting of eval argument.
2607 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2608 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2610 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2611 initialization of `ac_cv_exeext', do not override it if it was
2612 already set, unless it was set to `no', for compatibility with
2613 Autoconf-2.13, and comment this.
2614 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2615 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2616 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2617 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2618 Document that this test may be overridden by setting
2619 `ac_cv_exeext'.
2621 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2623 Revert these two patches:
2625 2006-04-06 Eric Blake <ebb9@byu.net>
2626 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2627 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2628 2006-04-01.
2630 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2631 Clean up _AC_COMPILER_EXEEXT* macros.
2632 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2633 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2634 ac_file to the name of the default output file and call
2635 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2636 initial `rm' of the candidate files...
2637 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2638 the same list in subsequent `rm' calls, and for the temporary
2639 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2640 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2641 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2642 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2643 no longer needed) by libtool. Make it a cache check.
2644 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2645 copied here by mistake.
2646 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2647 _AC_COMPILER_EXEEXT.
2648 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2649 _AC_COMPILER_OBJEXT directly.
2650 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2652 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2654 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2655 Fix description of how the buggy `sed' works.
2657 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2659 Sync from Automake:
2661 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2662 ENOLCK. Only mention `make -j' when applicable. Only raise
2663 fatal errors when `make -j' is involved. Improve error message.
2665 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2667 * doc/autoconf.texi (Here-Documents): We now know more about
2668 the variable expansion in here documents bug.
2669 Thanks to Tim Rice and Stepan Kasal.
2671 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2672 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2674 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2676 * tests/autotest.at (Multiline command from M4 expansion):
2677 No failure to be expected if the shell quotes newlines in
2678 commands in the `set -x' output. Report by Tim Rice.
2679 * THANKS: Update.
2681 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2683 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2684 expansion in the here-documents used by config.status, as that
2685 runs afoul of the Korn shell version M-12/28/93d bug described in
2686 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2687 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2688 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2690 2006-05-23 Jim Meyering <jim@meyering.net>
2692 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2693 Fix typo introduced with 2006-04-02 change. It reversed the sense
2694 of the test.
2696 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2698 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2699 ac_dB slightly, to save bytes in the script.
2700 Max out at 50 lines, rather than 96; this is more likely
2701 (though not guaranteed) to avoid obscure 'sed' failures.
2703 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2705 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2706 `tr -d -' as bad option argument. Work around this by deleting
2707 an unrelated character.
2708 Report by Tim Rice <tim@multitalents.net>.
2710 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2711 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2712 Stepan Kasal <kasal@ucw.cz>
2714 * doc/autoconf.texi (Particular Programs): Do not promise that
2715 we always prefer the GNU version of the program, and that we
2716 search according to PATH; both rules can have exceptions.
2717 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2718 AC_PROG_SED. Move descriptions of limitations
2719 to the Limitations of Usual Tools section.
2720 (Limitations of Usual Tools) <sed>: Mention script length
2721 limitations with Solaris /usr/ucb/sed.
2722 <grep>: Fix wording for empty alternative. Mention that -c and
2723 -l should not be combined, and that -E and -F should not be
2724 combined.
2726 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2727 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2729 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2730 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2732 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2734 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2735 AC_DEFINE is now passed to m4_pattern_allow.
2736 * NEWS: Mention that; likewise for AC_SUBST.
2737 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2738 the parameter to m4_pattern_allow.
2739 * tests/tools.at: Add a check for that.
2741 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2743 * lib/autoconf/status.m4: Fix typos.
2745 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2747 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2748 only the files that this macro generates.
2750 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2752 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2753 the HP-UX sed limitation of 99 commands, labels do not count.
2754 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2755 in the comment.
2756 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2758 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2760 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2761 Import the following fix from coreutils:
2763 2006-01-13 Jim Meyering <jim@meyering.net>
2765 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2766 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2767 not double-quote uses of that variable, to accommodate the rare
2768 case in which getmntent is available in none of the libraries
2769 checked. This happens at least on FreeBSD 5.0.
2771 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2773 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2774 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2775 some other programs unwisely rely on these undocumented vars.
2776 But put in warning comments about them.
2777 Problem reported by Ralf Wildenhues in
2778 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2779 * NEWS: Document that these variables are intended to go away.
2781 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2783 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2784 and set the language to C++ (analogous to the equivalent Fortran
2785 tests).
2787 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2788 * doc/autoconf.texi (C++ Compiler): Document it.
2789 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2790 * NEWS: Update.
2792 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2794 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2795 that caused config.status to generate 100-command sed scripts; the
2796 portable limit is 99.
2798 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2800 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2801 variable `ac_d' instead of `d' to avoid infringing namespace.
2802 Report by Ralf Menzel.
2804 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2806 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2807 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2808 * tests/tools.at (autoconf: subdirectories): New test, taken from
2809 the corresponding problem report by Ralf Wildenhues in:
2810 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2812 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2813 Quote some uses of shell variables if they might suffer unexpected
2814 globbing. This doesn't fix all instances of quoting problems that
2815 I found, just the easy ones that look safe.
2816 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2817 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2818 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2819 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2820 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2821 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2822 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2823 Likewise.
2824 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2825 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2827 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2829 * bin/autoreconf.in ($help): Reword according to the manual.
2830 Suggested by Olly Betts.
2832 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2833 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2835 * bin/autoreconf.in: Pass the directory argument to
2836 `require_configure_ac'. Fix comment.
2837 * tests/torture.at (Configuring subdirectories): Expose this.
2838 Reported by Olly Betts.
2840 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2842 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2843 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2844 Automake as follows:
2846 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2847 `$configure_in' instead of `configure.in', to preserve
2848 directory component.
2850 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2852 * config/config.guess, config/config.sub, config/texinfo.tex,
2853 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2855 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2857 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2858 test for C99 conformance; (bool) 0.5 is an integer constant
2859 expression, but (bool) -0.5 is not. Problem reported by Fedor
2860 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2862 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2864 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2865 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2866 Warn about obsolete install-sh files. Remove stray sentence
2867 fragment and fix cross reference.
2868 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2869 install -d; this undoes the 2006-05-10 change.
2870 (MKDIR_P): Mark with AN_MAKEVAR.
2871 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2872 that we don't require $INSTALL to be thread-safe. Move comments
2873 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2874 of AC_PROG_INSTALL. Output a message saying that we're checking
2875 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2876 MKDIR_P instead of AC_SUBST.
2877 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2878 Special magic for MKDIR_P, too.
2879 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2880 a dnl.
2881 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2883 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2885 Sync from Automake, as follows:
2887 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2888 * config/install-sh: Initialize IFS, so field splitting isn't
2889 turned off later.
2890 * config/mkinstalldirs: Likewise.
2891 * config/missing: Remove superfluous quotes. Replace all uses of
2892 `[' by `test', for consistency, and for..
2893 * config/missing (sed_minuso, sed_output): New variables.
2894 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2895 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2896 Fixes `missing' to detect `--output' for help2man. Fixes
2897 PR automake/483. Report by Dennis J. Linse.
2898 (autom4te): Document in `missing --help'.
2900 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2902 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2903 * config/install-sh: Don't use 'path' to talk about file names,
2904 as per GNU coding standards. Close a race condition reported by Ralf
2905 Wildenhues and Stepan Kasal. There is still a race condition
2906 on hosts that predate Posix 1003.1-1992, but we can't help this.
2907 Don't mishandle weird characters like space on pre-Posix hosts.
2908 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2909 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2910 AC_PROG_MKDIR_P from AS_MKDIR_P.
2911 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2912 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2913 earlier editions are not (including Automake 1.8.3).
2914 Do not suggest mkinstalldirs for thread-safety.
2915 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2916 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2917 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2918 presence of special characters and race conditions.
2919 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2920 in Autoconf's name space.
2922 2006-05-10 Bruno Haible <bruno@clisp.org>
2923 and Paul Eggert <eggert@cs.ucla.edu>
2925 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2926 from Automake with minor changes.
2927 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2929 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2931 * config/install-sh: Update to Automake CVS version, as follows:
2932 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2933 * lib/install-sh: Simplify the expr implementation of dirname.
2934 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2935 * lib/install-sh: Handle --, and diagnose unknown options.
2937 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2939 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2940 `./autom4te' to create `./testsuite', since the `all' target
2941 will ensure its presence, but `installcheck' should not create
2942 the uninstalled wrappers.
2944 * tests/torture.at (Unusual Automake input files): Skip if we
2945 detect automake < 1.8.
2947 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2949 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2950 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2951 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2952 * NEWS: Update.
2954 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2956 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2957 munge (multiple) white space and other oddities.
2958 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2959 single quotes in variable assignment.
2960 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2961 and similar failures by adding multiple spaces, tabs, and other
2962 special characters.
2963 Report and different test suggested by Francesco Romani
2964 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2966 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2967 single quotes, we only need to search for single quotes; this
2968 both simplifies the search pattern, and makes us less
2969 susceptible to `echo' variations for arguments not containing
2970 single quotes.
2971 (_AC_ARG_VAR_VALIDATE): Likewise.
2973 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2975 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2976 `$*' and IFS concatenation issue with traditional shells and
2977 bash-2.04. Report by Seanster@Seanster.com.
2979 2006-05-03 Bruno Haible <bruno@clisp.org>
2981 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2982 precisely which Mac OS X versions have the od problem.
2984 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2986 * doc/autoconf.texi: Use @option systematically.
2988 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2989 and Bruno Haible <bruno@clisp.org>
2991 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2992 about 'od'.
2993 (Integer Overflow): Mention the special case of integer division
2994 overflow.
2996 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2998 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2999 traditional shells like the Solaris one that do not use the
3000 first IFS character for assembling `$*'.
3001 Prompted by a related report from autoconf_bug@nro.ca.
3003 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
3004 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3006 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
3007 Mention more problems with the -e option.
3009 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3011 * NEWS: Typo.
3012 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
3014 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
3015 in URLs to improve DVI formatted output (requires texinfo 4.6).
3016 (System Services, Systemology, Shellology): Likewise.
3017 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
3018 output.
3020 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
3021 continuous text.
3022 (Runtime): Fix macro argument names to match description:
3023 `action-if-found' -> `action-if-true' and similarly.
3024 (Obsolete Macros): Likewise.
3025 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
3026 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
3027 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
3029 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3031 * doc/autoconf.texi (Limitations of Make): Clean up markup.
3033 * ChangeLog: Typo.
3034 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
3035 DVI output.
3037 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3039 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
3040 /bin/sh set unsorted output.
3041 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
3042 * tests/local.at: Likewise.
3044 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
3046 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
3047 (Integer Overflow, Null Pointers, Buffer Overruns):
3048 (Floating Point Portability, Exiting Portably): New sections.
3049 (Writing Test Programs): Fix some langauge. Recommend exiting
3050 with status 1, not merely nonzero. Clarify exit declaration.
3051 (Run Time): Move C exit status stuff to new Exiting Portably section.
3052 (Systemology): Mention Posix and levenez. Update v7 reference.
3053 (Portable Shell): Mention the Posix shell.
3055 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3057 * bin/autoconf.as (me): Replace by as_me.
3059 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
3061 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
3062 since as_me isn't set yet.
3064 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3066 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
3067 a few minor bugs in this area.
3069 * doc/autoconf.texi (Programming in M4sh): Comment out the
3070 documentation of AS_BASENAME, for now.
3071 (Shell Substitutions): Do not use AS_DIRNAME in an example.
3072 (Limitations of Builtins) <basename>: Do not refer to
3073 AS_BASENAME.
3074 * bin/autoconf.as (me): Don't use AS_BASENAME.
3075 (dir): Remove the unused variable.
3076 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
3077 AS_DETECT_REQUIRED. All uses changed.

3079 All uses changed.
3080 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
3081 (AS_BASENAME): Use "basename --" to protect against leading "-".
3082 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
3083 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
3084 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
3085 (_AS_DIRNAME_PREPARE): Likewise.
3086 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
3087 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
3088 (AS_DIRNAME): Use "dirname --".
3090 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3092 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
3093 of "run time" and "run-time" changed to "runtime", for consistency.

3096 * lib/autoconf/general.m4: Likewise.
3097 * lib/autoconf/headers.m4: Likewise.
3099 * doc/autoconf.texi (Run Time): Document the exit status situation
3100 with more accuracy and detail.
3102 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3104 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
3105 Archive is not officially `GNU' any more. Update URL.
3106 (Defining Directories): Likewise
3107 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
3109 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3111 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
3112 newline from the `trap' code to finish `config.log'; the NetBSD
3113 /bin/sh resets the exit status after an empty command, as
3114 documented in doc/autoconf.texi.
3115 Reported by Dalibor Topic <robilad@kaffe.org>.
3117 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
3119 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
3120 Suggested by Bruno Haible.
3122 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
3124 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
3125 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
3126 Instead, just list the shells that we know work.
3127 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
3128 changed. Be more cautious about the _cv_ variable.
3129 * tests/tools.at (Syntax of the shell scripts): Check the
3130 _cv_ variable once, at first, to avoid an internal autoconf error
3131 when sh -n does not work.
3133 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3135 * lib/Autom4te/FileUtils.pm: Sync from Automake.
3137 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
3139 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
3140 use ">&-" since we're only 99.999% sure that this is portable,
3141 and since the MinGW bug is fixed in a different way.
3142 * lib/autotest/general.m4 (AT_INIT): Likewise.
3144 2006-04-16 Stepan Kasal <kasal@ucw.cz>
3146 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
3147 before opening config.log, to avoid hitting a bug on MinGW.
3149 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
3151 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
3152 AS_MESSAGE_LOG_FD before reopening it onto the log file.
3153 This works around a MinGW bug reported by Eric Paire.
3154 Make sure that all writes to the log file append to it,
3155 rather than possibly losing data.
3156 * lib/autotest/general.m4 (AT_INIT): Likewise.
3158 2006-04-14 Stepan Kasal <kasal@ucw.cz>
3160 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
3161 description.
3163 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3165 * NEWS: Update.
3167 * configure.ac (AC_INIT): Bump to 2.59d.
3169 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3171 Version 2.59c.
3173 * Makefile.maint (news-date-check): Do not require a leading `*'
3174 before the release date in NEWS.
3176 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3177 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3179 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3180 the instantiated file do not contain the string 'datarootdir'
3181 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3182 @mandir@, replace the reference '${datarootdir}' by the value.
3183 * tests/torture.at (datarootdir workaround): New test.
3184 * NEWS: Advertise this temporary fixup.
3185 Based on a patch by Bruno Haible, reported and analyzed by
3186 Paul Eggert and Noah Misch.
3188 2006-04-12 Eric Blake <ebb9@byu.net>
3190 * tests/autotest.at (Debugging a failed test): Fix comment.
3192 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3194 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3195 all the changes since 2006-04-07.
3197 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3199 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3200 succeeded, but `ln -s file dir' failed, take care to remove the
3201 leftover target before the next test, to prevent its spurious
3202 failure; also make sure `ln file dir' works before selecting it.
3203 Thanks to Keith Marshall for pointing this out.
3204 * THANKS: Update.
3206 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3207 assignments in `at_debug_args', so that we put them correctly
3208 in the `run' script.
3209 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3210 Reported by Eric Blake.
3212 2006-04-11 Eric Blake <ebb9@byu.net>
3214 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3215 top-level tests after micro-suite has been run. Used in...
3216 (Debugging a successful test, Debugging script and environment),
3217 (Debugging a failed test): ...these new tests. The first of these
3218 is fixed by...
3219 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3220 macro, split out from...
3221 (AT_INIT): ...here, so that using -d also generates a run script.
3222 Document that -d inhibits top-level logging.
3223 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3224 inhibits top-level logging; debug scripts are created.
3226 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3227 check.
3228 * tests/autotest.at (Empty test, Empty check): New test to check it.
3230 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3231 from gcc.
3233 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3235 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3236 the files if a problem appears. Make the empty *.at files
3237 read-only, too. Proposed by Ralf Wildenhues.
3239 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3241 * config/Makefile.am: Add comment to force updated Makefile.in.
3243 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3244 space only patch to this file, this patch causes the Makefile.in
3245 files that include freeze.mk to be updated, and thus have a
3246 newer time stamp again, which in turn makes a pristine CVS
3247 checkout have correct time stamps.
3249 * Makefile.maint (cvs-sv): New macro, to be used..
3250 (config.guess-url_prefix, config.sub-url_prefix)
3251 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3252 point to CVS text checkout of Gnulib files.
3253 (copyright-check): Bump current year.
3254 (announcement): Do not hard-wire `./announce-gen'.
3255 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3256 correctly.
3257 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3258 `chmod +x'.
3259 (wget_files): Update config.guess, config.sub, texinfo.tex by
3260 `wget-update', now that their URLs work again.
3262 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3264 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3265 Problem noted by Paul D. Smith.
3267 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3269 * doc/autoconf.texi: Remove unused words from word list.
3270 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3271 .x-sc_trailing_space: New files.
3273 * doc/standards.texi: Sync from gnulib.
3275 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3276 `LIBOBJDIR' as experimental.
3278 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3279 with a target directory; it's internally implemented as `cp'
3280 anyway, but since Autoconf advertises the possibility to use
3281 a target directory when LN_S is `ln -s', we need to find out.
3282 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3283 analyzed by Keith Marshall <keith.marshall@total.com>.
3285 * THANKS: Update.
3287 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3289 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3290 confdefs.h as-is. In general, if it has backslash-newline or the
3291 like, then it doesn't work either to sort or to remove empty
3292 lines.
3294 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3296 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3298 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3300 * lib/autom4te.in (Automake-preselections): Preselect
3301 _AM_SUBST_NOTMAKE.
3303 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3305 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3306 apostrophe within a single-quoted string, as this is the usual
3307 tradition and is easier to read than '"'"'. Don't rely on the
3308 shell treating "$/" like '$/'. Use a more-consistent indenting
3309 style for the trap.
3311 2006-04-09 Eric Blake <ebb9@byu.net>
3313 * tests/autotest.at (Backquote command substitution),
3314 (Multiline backquote command substitution): Remove mistaken
3315 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3316 applied...
3317 (Parenthetical command substitution, Multiline parenthetical
3318 command substitution): here.
3320 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

3337 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
3338 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3339 Gnulib section.
3340 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
3341 suggest a #define rather than a typedef for _Bool, and mention
3342 Gnulib rather than trying to substitute stdbool code.

3344 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
3345 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

3350 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
3351 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
3352 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
3353 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3354 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3355 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3356 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3357 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3358 (Coding Style). Don't mention m4_expand_once.
3359 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
3360 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
3361 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
3362 (AC_CHECK_FUNCS): Use it.

3367 (AC_HEADER_ASSERT): New macro.
3368 (AC_HEADER_STDBOOL): Don't assume "#error" works.
3369 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
3370 Catch a bug in an HP-UX C compiler.
3371 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
3372 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
3373 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
3374 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):

3376 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
3377 New macros.
3379 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
3380 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
3382 2006-04-08 Stepan Kasal <kasal@ucw.cz>
3384 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
3385 of the warning introduced by the 2001-08-28 change.
3387 2006-04-08 Stepan Kasal <kasal@ucw.cz>,

3390 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
3391 variables shall be overriden by the cache.

3393 that contains braces.
3395 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3397 Revert the patch from 2006-04-01 and only improve
3398 _AS_DETECT_BETTER_SHELL:
3400 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3401 skip nonexistent directories.
3402 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3403 only shell candidates which exist.
3404 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3405 * lib/autotest/general.m4 (AT_INIT): No need to give three
3406 parameters to _AS_PATH_WALK.
3408 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3409 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3411 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3412 distinguish m4sugar macros.
3413 * tests/tools.at (autoupdating with aclocal and m4_include):
3414 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3415 test case by Noah Misch <noah@cs.caltech.edu>.
3417 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3419 Revert my change from 2006-03-17, in other words:
3420 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3421 and DUALCASE=1.
3422 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3423 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3424 it is set.
3426 2006-04-07 Eric Blake <ebb9@byu.net>
3428 * doc/autoconf.texi (Programming in M4sh): Document that
3429 AS_MKDIR_P exits the script on failure.
3430 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3432 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3434 * config/elisp-comp, config/install-sh, config/mdate-sh,
3435 config/missing, config/mkinstalldirs: Sync from Automake.
3437 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3438 from Automake.
3440 * doc/make-stds.texi: Sync from gnulib.
3442 2006-04-06 Eric Blake <ebb9@byu.net>
3444 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3445 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3446 2006-04-01.

3449 Eric Blake <ebb9@byu.net>,
3450 Paul Eggert <eggert@cs.ucla.edu>,
3451 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3453 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3454 whether `set' quotes correctly: redirect stderr of the tested
3455 `set', and use a subshell, for Ultrix; use `sed' instead of
3456 `grep' for zsh `set' which may write binary output; match only
3457 at the beginning of a line, to avoid false positives.
3458 In order to avoid false positives by unrelated variables with
3459 multiline content, put the dump algorithm in a subshell and
3460 unset all variables containing newlines (except some which are
3461 special to the shell). Warn about cache variables that are
3462 unset.
3464 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3466 * config/config.guess, config/config.sub, config/texinfo.tex:
3467 Sync from upstream.
3469 * tests/mktests.sh: Reword comments.
3471 * tests/mktests.sh: Only skip internal macros starting with
3472 `_AC_' or `__AC_'. Noted by Stepan Kasal.

3474 (AC_ARG_VAR): Do test this now.
3475 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3476 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3477 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3478 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3480 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3481 shell issue with double-quoted command substitutions of native
3482 commands.
3483 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
3484 Marshall.
3486 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

3489 (sc_cast_of_x_alloc_return_value): Likewise.
3490 (sc_cast_of_alloca_return_value, sc_error_exit_success)

3492 (m4-check): Likewise.
3493 (sc_system_h_headers): Do not print rule on execution.
3494 (sc_tight_scope): Do not fail for non-existing `src' directory.
3495 (sc_changelog): Skip the Copyright footer.
3496 * lib/autoconf/lang.m4: Remove trailing space.
3498 * lib/autoconf/status.m4: More replacements to
3499 <tab><space> where this makes sense.
3501 2006-04-06 Stepan Kasal <kasal@ucw.cz>
3503 * tests/Makefile.am (maintainer-check-posix):
3504 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
3506 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
3507 ac_config_<foo>s again, sometimes normalized, sometimes not.
3508 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3509 (AC_CONFIG_COMMANDS): Do not do so here.
3510 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3511 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3512 2005-07-25 rewrite. Noticed by Noah Misch.
3514 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3515 _AC_PRESERVE_HELP_ORDER, ...
3516 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3518 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3519 inside m4_expand_once; it is redundant.
3521 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3522 for --help from Cygnus `configure.'
3524 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
3526 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
3527 on a patch proposed by Ralf Wildenhues.
3529 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3531 * lib/autoconf/status.m4: Replace <space>''<tab> with
3532 <tab><space> where this makes sense.
3534 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
3535 Noah Misch <noah@cs.caltech.edu>
3537 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3538 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3539 * doc/autoconf.texi (Help Formatting): New node.
3540 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3542 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3544 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3545 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3546 lib/autoconf/types.m4, lib/autotest/general.m4,
3547 tests/mktests.sh, tests/torture.at: White space cleanup:
3548 remove some SPACE before TAB, or add quoting ('' or @&t@).
3550 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
3552 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
3554 2006-04-05 Eric Blake <ebb9@byu.net>
3556 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
3557 empty test suite works.
3558 * tests/autotest.at (Empty test suite): Remove xfail.
3560 2006-04-05 Noah Misch <noah@cs.caltech.edu>
3562 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
3563 TAGS to ac_config_<foo>s.
3564 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
3565 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
3566 normalizing it, consistent it with previous releases.
3567 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3569 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3571 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3572 Use simplified args that Eric Blake originally suggested.
3574 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3576 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3577 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3578 Use 'comm' rather than N instances of grep; this also fixes a bug
3579 whereby substrings were incorrectly matched, causing us to not
3580 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3581 (exclude_list): Exclude empty macros.
3582 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
3584 Use awk rather than grep -E or egrep, to avoid
3585 portability problems with regular expressions containing newlines.
3586 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
3587 Switch from grep to awk syntax.
3588 (ac_exclude_script): Renamed from ac_exclude_egrep.
3589 (au_exclude_script): Renamed from au_exclude_egrep.
3591 2006-04-04 Noah Misch <noah@cs.caltech.edu>
3593 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
3594 a subdirectory subject to Cygnus `configure'.
3595 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3597 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3598 report request when we have no AC_PACKAGE_BUGREPORT.
3600 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3602 * THANKS: Update.

3605 generated files.
3607 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
3608 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
3609 typedef'ed restricted pointer, to catch a compiler bug on
3610 HP-UX 11.x, and fix warnings so it passes with -Werror.
3611 (_AC_PROG_CC_C99): Likewise.
3612 Reported by Albert Chin <china@thewrittenword.com>.
3613 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.
3615 2006-04-03 Noah Misch <noah@cs.caltech.edu>
3617 * bin/autoscan.in (subdirs): New global.
3618 (scan_file): Prune directories with configure{,.{ac,in,gnu}}.
3619 (output): Emit AC_CONFIG_SUBDIRS as needed.
3620 * tests/autoscan.at (autoscan): Remove XFAIL.
3622 2006-04-03 Noah Misch <noah@cs.caltech.edu>
3624 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
3626 2006-04-03 Eric Blake <ebb9@byu.net>
3628 * THANKS: Add myself.
3630 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3632 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
3633 to log, point to testsuite output tree.
3635 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
3637 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
3638 * doc/autoconf.texi (Function Portability): Mention that C++
3639 has trouble with 'exit'.
3640 (Guidelines): Test programs shouldn't use 'exit'.
3641 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
3642 Remove; all uses removed.
3643 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):
3644 Return from 'main' instead of calling 'exit'.

3668 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3669 initial `rm' of the candidate files...
3670 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3671 the same list in subsequent `rm' calls, and for the temporary
3672 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3673 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3674 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3675 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

3756 switch all of them on and of when necessary. Fixes the bug when
3757 m4sugar macros (e.g., m4_define) were expanded after the first
3758 automatic update (e.g., after AC_PREREQ or AC_INIT).

4015 newline for portability.
4016 * tests/torture.at (Torturing config.status): Also test 100

4456 by the function rather than ignoring it.
4457 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4458 comparing its address. Intel's interprocedural optimization was

4477 Stepan Kasal <kasal@ucw.cz>
4479 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4480 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4481 make its content writable before removing it. Remove an errorneous
4482 comment from the end, where the logs of the failed tests are copied
4483 to the main log file.
4485 2005-09-27 Stepan Kasal <kasal@ucw.cz>

4492 problems if the testsuite were running too fast.
4494 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4496 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

4508 suggested by Ben Elliston. Handle weird characters correctly.
4510 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4512 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4513 calls, so that the final expansion of this macro is shorter.
4514 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4515 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4516 the cleanup there. Use AS_VAR_* macros, to be more general.
4517 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4519 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4521 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

4542 in the example. Reported by Bruno Haible.
4543 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4544 "if $undefined_var;" succeeds with my shell.
4546 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4547 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

4571 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4572 ``Configuration Actions''; fix their index entries.
4574 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4575 options correctly. Process N-M as M-N if M is smaller than N.
4576 Process ranges correctly so that N-N will run only N.
4577 Sort and uniquify the tests that will be run. If there is more
4578 than one test, reinsert the banners for the tests.

4609 When building in place, set srcdir="."; suggested by Tim Van Holder.
4611 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4612 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4613 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4614 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

4649 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4651 Rewrite substantial part of lib/autoconf/status.m4.
4652 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4653 and CONFIG_COMMANDS are not processed in four separate loops.
4654 Instead, there is one main loop. This alows that the common code
4655 is expanded only once, thus config.status (and configure) is smaller.
4657 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4658 the AC_LIST_FILES and cousins macros are no longer used.
4660 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4661 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4662 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4663 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4664 contain the initialization, nor the for loop, nor the associated
4665 commands; all these go to ...
4666 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4667 _AC_OUTPUT_CONFIG_STATUS.
4668 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4669 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4670 (_AC_OUTPUT_FILE): The creation of the sed script ...
4671 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4672 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4673 _AC_OUTPUT_MAIN_LOOP.
4674 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4675 _AC_CONFIG_COMMANDS): Use ...
4676 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4677 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4678 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4679 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4680 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4681 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4682 ... new macros.
4683 (_AC_CONFIG_UNIQUE): Update.
4684 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4685 Replaced by this ...
4686 (_AC_LIST_TAGS): ... new common macro.
4687 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4688 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4689 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4690 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4691 this didn't belong to the `config commands' section.
4692 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4693 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4694 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4695 to the `config commands' section either.
4696 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4697 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4699 ... and many changes to the comments nearby.
4701 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4702 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4703 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4704 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4705 (#define header templates): The comment at the top of the generated
4706 header now includes the name(s) of the source file(s).
4708 Several unrelated small changes:
4710 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4711 parameter to AC_DIAGNOSE.
4712 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4713 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4714 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4715 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4716 with AU::AC_OUTPUT.
4717 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4718 in AC_OUTPUT doesn't double-quote it either.
4719 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4720 parameters.
4722 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4724 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4725 versions of Portland Group compiler produce single- and double-quoted
4726 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4727 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4729 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4731 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4732 This is a corrected version of yesterday's patch.
4734 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4736 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full

4740 ac_cv_build_alias to ac_build_alias.
4741 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4743 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4744 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4745 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4746 (AC_ARG_VAR): ... here.
4747 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4748 target_alias.
4750 Keep a list of all precious variables and process them with one simple
4751 for loop, instead of expanding all commands, or, OTOH, complicated
4752 processing of output of "set".
4753 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4754 variable names in new macro...
4755 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4756 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4757 a loop to assign all ac_env_* and ac_cv_env_* variables.
4758 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4759 to INIT_PREPARE.
4760 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4761 its value to shell variable ac_precious_vars and call
4762 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4763 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4764 _AC_ARG_VAR_VALIDATE.
4766 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4767 and the AC_SUBSTs ...
4768 (AC_INIT): ... here.
4770 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4771 the ac_subst_files section in config.log.
4773 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

4782 Fix problems reported by Nicolas Joly.
4783 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
4784 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4785 They are generated by the Tru64 v5.1B shell.
4787 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4789 Fix my changes from 2005-07-01; reported by Noah Misch.
4790 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4791 description, the macro now accepts only a single tag.

4794 Fix cases when the varsions of Autoconf and Autotest don't match.
4795 Reported by Noah Misch.
4796 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4797 at_top_builddir, for compatibility with older autotest.
4798 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4799 is not set, use at_top_builddir, for compatibility with older
4800 versions of autoconf.
4802 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4804 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4805 Problem reported by Patrick Welche.
4807 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4809 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4810 sed substitution command, so that we allow | in program prefixes
4811 and program suffixes. (& is a problem anyway; we're not fixing
4812 that here.)
4813 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4814 configure_input, top_builddir, srcdir, etc.
4815 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4816 PATH_SEPARATOR in AUTOTEST_PATH.
4818 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4820 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4821 for loop over config.site files using `set', to allow
4822 directory names containing IFS characters.

4826 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4827 directories with weird names. Apparently some people like living
4828 on the edge. However, improve the test that "pwd" actually does
4829 report a name for the working directory.

4848 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4849 document to output the default config_* lists to config.status.
4850 Don't recognize option --file, if the functionality is not there.
4851 Likewise for --header; moreover, recognize --he and --h as shortcuts
4852 for --help in that case.
4854 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4855 matches the order of execution. No code changed.

4877 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4878 (AC_SUBST): Call it.
4879 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4880 the directory specific variables; but don't call it for configure_input.
4882 2005-06-28 Derek Price <derek@ximbiot.com>
4884 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4885 addition.
4887 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4889 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4890 directory have inherent problems with special characters like spaces,
4891 due to limitations in Make syntax. Problem reported by Alexandre
4892 Duret-Lutz.
4893 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4908 variable into diagnostic. Make the diagnostic an error, not a warning,
4909 because we really don't support spaces and suchlike in dir names.
4910 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4911 Don't worry about backslashes in srcdir; it can't happen now.

4922 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4924 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4925 that '\|' is not allowed in BREs; recommend using newline separated

4928 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4930 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4938 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4939 b, t, r, w commands require single space, while : cannot have any.
4940 (Special Shell Variables): Fix sed code this in the example.
4941 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4942 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4944 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4945 expand to the empty list. Don't use two pairs of m4_changequote,
4946 it's not necessary.
4948 2005-06-20 Derek Price <derek@ximbiot.com>
4950 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4952 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4954 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4955 * doc/autoconf.texi:
4956 Don't mention Solaris versions so much, if a
4957 problem is common to all extant versions of Solaris. Say "SunOS
4958 4" instead of "SunOS" for SunOS 4.
4959 (awk): Mention more of the limitations of traditional Awk.
4960 (cat): Don't talk about cat -v.
4962 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4964 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4965 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

4967 to be compatible with glibc strverscmp.
4968 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4970 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4971 on Mac OS X 10.4 reported by Peter O'Gorman in:
4972 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4973 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4974 Use shell builtins rather than 'expr', to work around expr bug.
4976 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4978 * doc/autoconf.texi: "filesystem" -> "file system".
4979 "behaviour" -> "behavior".
4980 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
4981 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4982 as per POSIX.
4983 * lib/m4sugar/m4sh.m4: Likewise.

4985 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4987 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4988 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4989 to update the man page. That way, we don't have to check in new

4992 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4993 quotes and backslashes. Patch from Derek Price.

5003 -u, since it outputs chatter if the input files are the same.
5004 Problem reported by Ralf Menzel.
5006 2005-06-08 Derek Price <derek@ximbiot.com>
5008 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
5009 renaming them since they are about to be redefined anyhow.
5011 2005-06-08 Derek Price <derek@ximbiot.com>
5013 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
5014 redefined M4 macros to this node. Document m4_include & m4_sinclude.
5015 Move m4_undefine to alphabetical order.
5017 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
5019 * README: Recommend GNU M4 1.4.3 or later.
5020 * doc/autoconf.texi (Introduction): Likewise.
5021 Reword to avoid some formatting glitches.
5022 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
5023 Clarify explanation of HP compiler bug.
5024 Redo example output tp match current CVS snapshot.
5025 Use @example.org in email addresses when the examples
5026 might get inadvertently cut-and-pasted into user code.
5027 Remove example of autom4te usage that doesn't seem to work now.
5028 Use modern AC_INIT (except when the example is meant to be
5029 shown with Autoconf 2.13).
5030 Update ksh info for Solaris 9 and later.
5031 KB -> kB.
5032 Modernize description of Automake versions a bit.
5033 Don't claim a future version of Autoconf is near.
5034 * doc/install.texi: Reword to avoid some formatting glitches.
5036 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5038 * doc/autoconf.texi: Add [] to examples, so that the manual
5039 follows its own advice about quoting better.
5040 Reword to avoid some formatting glitches.
5041 * doc/installt.exi: Reword to avoid some formatting glitches.
5043 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
5044 Tru64 ksh pattern matching bug. Reported against Libtool by
5045 Albert Chin <libtool@mlists.thewrittenword.com> and
5046 Nicolas Joly <njoly@pasteur.fr>.
5048 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5050 m4_cdr of one-member list was [[]] (one-member list containing an
5051 empty string) instead of [] (an empty list. Callers were skewed to
5052 match this misbehaviour. As a consequence of this:
5053 - m4_foreach([x], [], [foo]) expanded to `foo', while
5054 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
5055 This bug has been fixed:
5057 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
5058 expand to an empty string; print error msg if called without
5059 an argument list.
5060 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
5061 misbehaviour; handle [] and [[]] correctly.
5063 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5065 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
5066 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
5067 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
5069 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
5071 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
5072 swallow records with more than 99 fields.
5073 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
5074 parse the long line.
5076 2005-06-04 Stepan Kasal <kasal@ucw.cz>
5078 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
5079 swallow literals longer than 399. Reported by Ralf Wildenhues.
5080 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
5081 to workaround this limitation.
5083 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
5085 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
5086 to gfortran, and make these the first two compiler names
5087 checked (following the general autoconf preference for gcc).
5089 2005-06-03 Stepan Kasal <kasal@ucw.cz>
5091 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
5092 (DISTCLEANFILES): Remove $(check_SCRIPTS).
5093 (testsuite): Make sure autotest.m4f is up-to-date before using it.
5095 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
5097 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
5098 expression of unbounded size when processing the --list
5099 option. This runs afoul of a limit of 399 bytes per regular
5100 expression on AIX. Problem reported by Ralf Wildenhues.
5102 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
5104 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
5105 * doc/autoconf.texi (Particular Headers): Reword example
5106 for multiline stdbool replacement.
5107 (Setting Output Variables): Reword text a bit. Don't
5108 give all the details about |#_!!_#|.
5109 Reword description of line replacement.
5111 2005-05-31 Dan Manthey <dan_manthey@partech.com>
5113 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
5114 now contain newlines, and substituted files must be referenced on
5115 a line alone; the sed scripts to substitute them are now very
5116 different.
5117 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
5118 commands can be put in a sed script portably.
5119 * doc/autoconf.texi (Setting Output Variables): Document above
5120 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
5121 use of multiline substitution.
5122 * tests/torture.at: No longer expect substitution of newline to fail.
5124 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
5126 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
5127 From Ralf Menzel (trivial change).
5129 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
5131 * tests/local.at: Don't attempt to check for negated character
5132 classes in shell scripts. The test was too brittle.
5134 2005-05-25 Stepan Kasal <kasal@ucw.cz>
5136 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
5137 * doc/autoconf.texi (Limitations of Builtins): Document this
5138 limitation.
5140 2005-05-24 Stepan Kasal <kasal@ucw.cz>
5142 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
5143 common code; used in many places in the tree.
5144 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
5145 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
5147 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
5149 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
5150 messages when ac_unique_file is not found.
5151 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
5152 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
5153 commands, for consistency with AC_MSG_ERROR and such.
5155 * bin/autoconf.as: Make more use of "shift 2" in option processing.
5157 * bin/Makefile.am: Merge the two rules for creating scripts.
5159 2005-05-23 Stepan Kasal <kasal@ucw.cz>
5161 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
5162 obsolete; it was never documented.
5163 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
5165 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5167 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
5168 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
5169 (ac_top_builddir): ... this ...
5170 (ac_top_build_prefix): ... to this; the old name is also kept, for
5171 backward compatibility.
5172 (ac_top_builddir_sub): New variable, without the trailing slash,
5173 always nonempty.
5174 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
5175 * doc/autoconf.texi (Configuration Actions): Rename
5176 ac_top_builddir to ac_top_build_prefix.
5177 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
5178 at_top_builddir to at_top_build_prefix.
5179 * lib/autotest/general.m4 (AT_INIT): Likewise.
5181 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5183 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
5184 of confdefs.h .
5186 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5188 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
5189 argument to m4_foreach. I guess it was necessary in the past,
5190 but I think it's a no-op now.
5192 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5194 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5195 ``cat <<_ACEOF'' commands to one.
5196 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
5197 * lib/autoconf/status.m4: On various places, use expr instead of
5198 ``echo|sed.''
5199 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
5200 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
5201 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
5202 a range.
5203 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
5204 the wrong patterns between ``case'' and ``esac.'' The previous
5205 code had false positives.
5207 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
5209 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
5210 as on 2005-05-02.
5211 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
5212 Mention LIBOBJDIR.

5250 Update FSF postal mail address.
5252 2005-05-13 Stepan Kasal <kasal@ucw.cz>
5254 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
5255 check.
5256 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
5257 enough arguments, similarly as in m4_bpatsubsts.
5259 2005-05-12 Stepan Kasal <kasal@ucw.cz>
5261 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

5264 2005-05-11 Stepan Kasal <kasal@ucw.cz>
5266 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
5267 for absolute directory names in one loop.
5268 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
5269 abbreviations of --version and --debug.
5271 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
5273 * doc/autoconf.texi (Autoconf Language): Be more precise about
5274 quoting rules. Problems noted by Stepan Kasal.
5275 Also, throughout this document, be more careful about white space.
5276 "blank", "white space", and "space" all have different meanings
5277 and we should be careful to say what we mean.
5279 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
5281 Fix C++ related problems reported by Werner Lemberg.
5282 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
5283 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
5284 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
5285 avoid problems with C++ and throw.
5286 * tests/compile.at: .cpp, not .cc.
5288 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
5290 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5292 * doc/autoconf.texi (Generic Functions): Typos.
5294 2005-05-02 Gary V. Vaughan <gary@gnu.org>
5296 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
5297 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
5298 set by latest automake.
5300 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
5302 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
5303 outputs 0 on GNU/Linux these days.
5305 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
5307 * doc/autoconf.texi (Autoconf Language): Add more description
5308 about quoting heuristics.
5309 (Limitations of Builtins): Describe "set -" problems.
5311 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5313 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
5314 not newline.
5316 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5317 by AC_DEFINE; it was a mistake.
5318 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5320 2005-04-25 Stepan Kasal <kasal@ucw.cz>
5322 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
5324 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5326 * doc/autoconf.texi (External Software): Quadrigraphs are not
5327 processed correctly in AS_HELP_STRING; avoid this in the examples.
5328 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5329 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5330 comment and reduce m4_default([foo], []) to [foo].
5331 (m4_strip): Update the explanation.
5333 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5335 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5336 Remove core.conftest.* too; it's generated by Tru64 5.1.
5337 Problem reported by Jennis Pruett.
5338 * lib/autoconf/functions.m4
5339 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5340 Don't bother to remove core files; AC_RUN_IFELSE should do that
5341 for you.
5343 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5345 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
5347 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
5349 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

5362 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
5364 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
5365 as well as configure.in. Problem reported by Gregorio Guidi.
5367 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
5369 * doc/autoconf.texi (Particular Functions): Use gnulib's current

5383 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
5385 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5387 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5388 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5389 whole-archive (-zallextract, -zdefaultextract) options in the hope of
5390 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5391 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5393 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5395 * NEWS: The configure command now warns you if you attempt to use
5396 a directory whose name contains a special character like space,
5397 newline, or "\".
5398 * doc/autoconf.texi (Installation Directory Variables): Allow
5399 "," in file names. Do not use \@; it's not a portable regexp.
5400 * bin/Makefile.am (edit): Likewise.
5401 * lib/Makefile.am (edit): Likewise.
5402 * tests/Makefile.am (edit): Likewise.
5403 * tests/semantics.at: Likewise.
5404 * tests/torture.at: Likewise.
5405 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
5406 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
5407 * doc/autoconf.texi (File System Conventions): Warn about
5408 unportable file names.
5409 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5410 (AC_INIT): Use it.
5411 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5412 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5413 ac_pwd, and quote srcdir.
5414 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5416 * doc/autoconf.texi: Fix some systematic formatting problems.
5417 ".)" needs a following @: if not at the end of a sentence, and
5418 similarly for "!)". "etc." should be preceded by a comma.
5419 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5421 2005-03-22 Bruno Haible <bruno@clisp.org>
5423 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5424 argument is often called 'build-aux'.
5426 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5428 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5429 macro AC_TRY_LINK is obsolete.
5430 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5431 `AC_CONFIG_FILES'.
5433 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5435 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5436 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5437 from a Common Lisp's `cl'.
5438 (AC_PROG_CXX): Behave according to the documentation: don't
5439 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5440 make the variable CCC precious; use `cl.exe', not `cl'.
5442 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5443 Alexandre Duret-Lutz <adl@gnu.org>
5445 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5446 /dev/null, as "configure" shouldn't read stdin, and this insulates
5447 us from problems (e.g., when testing for "cl"). Also, do this
5448 redirection before invoking "hostname" or "uname", and keep the
5449 original input stream available via...
5450 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5451 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5452 bother with "</dev/null" since it's now done at the top of
5453 'configure'.
5454 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5455 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5456 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5457 * doc/autoconf.texi (File Descriptor Macros): New section.
5458 (Printing Messages): Mention it.
5459 * tests/base.at (Input/Output): New test.
5461 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5463 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5464 newline if neither \c nor -n work, as that would output two
5465 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5467 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5469 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5470 This causes that any required macros inside will get before the if.
5471 * doc/autoconf.texi (autom4te.cache): A typo.
5473 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5475 Undo previous change, except keep the change to
5476 lib/autoconf/programs.m4 that replaced grep with shell
5477 pattern-matching. This is because net-snmp configure reads stdin.
5478 Reported by Noah Misch.
5480 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5482 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5483 from /dev/null, as "configure" shouldn't read stdin, and this
5484 insulates us from problems (e.g., when testing for "cl").
5485 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5486 before invoking "hostname" or "uname".
5487 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5488 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5489 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5490 "</dev/null" since it's now done at the top of 'configure'.
5491 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5492 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5493 Also, replace grep with shell pattern-matching, to save a process.
5495 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5497 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5498 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5499 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5500 compiler.
5502 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5504 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5505 grep -q isn't portable. Improve grep -s explanation.
5506 Problem reported by Dan Manthey.
5508 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5510 * doc/autoconf.texi (Special Shell Variables): Clarify
5511 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5513 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5515 * doc/autoconf.texi: Use @acronym for DJGPP.
5516 Fix some @code's that should have been @env's, and vice versa.
5517 Sort environment variable names.
5518 Mention that shells no longer inherit IFS.
5519 Don't recommend PATH_SEPARATOR=';' so strongly.
5520 Mention that $RANDOM might expand to the empty string.
5521 "symlink" and "soft link" -> "symbolic link".
5522 Improve mktemp description (reported by Bruno Haible).
5524 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5526 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5527 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5528 Likewise.
5529 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5530 Likewise.
5532 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5534 * NEWS: Mention AT_COPYRIGHT.
5536 * tests/local.at (AT_CMP): Use diff directly on input files rather
5537 than copying them.
5539 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5540 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5542 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5543 and Paul Eggert <eggert@cs.ucla.edu>
5545 * tests/autotest.at (Empty test suite): New test.
5546 * tests/torture.at (Substitute and define special characters)
5547 (Substitute a 2000-byte string, Define to a 2000-byte string)

5554 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5555 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5556 (Standard regular expressions): New test.
5557 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5558 excess test name quoting.
5559 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5560 CPPFLAGS to `configure' instead of setting it in `configure'.
5562 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5563 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5564 on some platforms.
5566 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5567 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

5591 and Paul Eggert <eggert@cs.ucla.edu>
5593 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
5595 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
5597 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5598 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5600 Try not to generated lines of unlimited length, as POSIX places a
5601 2047-byte limit on line length of portable text files.
5602 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5603 Use newline as a separator, not space.
5604 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
5605 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
5606 space.
5608 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5610 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
5611 as_func_*. Add test to check whether positional parameters
5612 are restored after function return.
5614 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
5616 * doc/autoconf.texi (Special Shell Variables): Mention _,
5617 BIN_SH, DUALCASE. Say that variables other than "status" are safe
5618 if they contain a lower-case letter. The DUALCASE problem was
5619 reported by Ralf Wildenhues.
5621 * bin/autoconf.as: Don't exit with status 0 after write failure
5622 with --help or --version.
5623 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
5624 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

5628 * doc/autoconf.texi (Limitations of Usual Tools):
5629 Unicos 9 sed limitations.
5630 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

5632 Fortran 95 (newer Crays).
5634 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
5636 * man/Makefile.am (.x.1): Go back to the simple solution, but take
5637 care to echo the commands, so the user knows what's going on.
5638 Modified from a suggestion by Stepan Kasal.
5640 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
5641 with a cross reference. Derived from a suggestion by Bruce Korb.
5643 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
5645 * doc/autoconf.texi (config.status Invocation): Warn about

5648 Based on a proposed patch by Ralf Wildenhues.
5650 * man/Makefile.am (.x.1): Make sure the required generated files
5651 are up to date. Problem and original solution proposed by Stepan Kasal.

5661 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5662 Update the long comment explaining it.
5664 m4_require no longer writes an ``is required by'' line to the
5665 execution stack. It contains only one bit of non-redundant
5666 information: that the macro was required, not called. And even
5667 this bit is useless in most situations: have you ever met a macro
5668 which both calls and requires the same macro?
5670 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5671 (_m4_defun_pro_outer): ... only via this macro, for the outermost
5672 macro.
5673 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
5674 (m4_expansion_stack_pop): Remove the misplaced comment.
5675 (m4_require): Don't put the ``is required by'' line to the
5676 execution stack; slightly improve the out-of-a-defun error message.
5677 (_m4_divert_grow): New macro, counter for the temporary diversions.
5678 (_m4_require_call): Use it.
5679 * tests/m4sugar.at (m4_require): Expect output without the
5680 ``is required by'' messages.
5682 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5684 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5685 rather than x for expr.
5687 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5688 this is safe.
5689 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
5690 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5691 * lib/autotest/general.m4 (AT_INIT): Likewise.

5700 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
5701 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
5702 from masters, so that FileUtils.pm's update_file provide --force
5703 support.
5704 * bin/autoheader.in: Pass $force to update_file so that
5705 config.h.in is always recreated when --force.
5707 2005-01-24 Stepan Kasal <kasal@ucw.cz>
5709 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
5711 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
5713 * doc/autoconf.texi (Limitations of Builtins): Clarify that
5714 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
5716 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5718 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5719 Warn about newline stripping in `` and $(). Update Solaris
5720 version to 9.
5721 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5722 X insulates us from future changes to Posix.
5723 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
5724 stripping.
5726 2005-01-19 Stepan Kasal <kasal@ucw.cz>
5728 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
5729 you cannot use AC_DEFINE to define macros containing `[' or `]'.
5731 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
5733 * doc/autoconf.texi (Limitations of Usual Tools): Document bug
5734 in Solaris 8 join. Problem reported by Tomohiro Suzuki on

5744 ulongval to be static, to avoid unwanted GCC warning. Problem
5745 reported by Michael Jennings via Daniel Reed; see
5746 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
5748 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5750 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
5751 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
5752 datadir, infodir, and mandir. Adjust argument parsing code.
5753 (_AC_INIT_HELP): Update help text.

5755 new variables.
5757 2005-01-04 Noah Misch <noah@cs.caltech.edu>
5759 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
5760 not seem to work, assume it does set $(MAKE).
5761 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
5763 2005-01-03 Stepan Kasal <kasal@ucw.cz>
5765 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

5771 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
5772 (_m4_divert_n_stack): New macro; the expansion is
5773 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
5774 otherwise.
5775 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5776 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5777 stored in _m4_divert_diversion or _m4_divert_dump.
5778 (m4_divert_pop): When the parameter is given, compare the symbolic
5779 name with the last diversion pushed on the stack. Previously, the
5780 current diversion was compared with the numeric value of the
5781 diversion given as the parameter.
5782 (m4_require): If the macro hasn't been expanded yet, call ...
5783 (_m4_require_call): this new macro.
5785 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5814 2004-12-30 Noah Misch <noah@cs.caltech.edu>
5816 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
5817 signals that the package uses Automake; a `Makefile.am' is typical but
5818 not essential. Reported by Magnus Therning.
5819 * tests/torture.at (autoreconf.): New banner.
5820 (autoreconf and non-AC configure): Rename to `Non-Autoconf
5821 AC_CONFIG_SUBDIRS'.

5867 2004-12-21 Stepan Kasal <kasal@ucw.cz>
5869 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
5870 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are
5871 no longer part of the macro, quote the occurrence of ``$tmp''.

5997 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

6062 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>

6065 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
6066 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

6088 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
6090 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
6091 "char c = '\200';" rather than "char c = 0x80;" as the
6092 latter doesn't conform to the strict C standard due to
6093 overflow on signed char hosts.
6095 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
6096 to -qlanglvl=ansi. We don't want to disable extensions.

6100 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

6116 Automake (not without Autoconf).
6117 (Introduction): Mention lists.gnu.org.

6156 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
6157 the $1_found variable, don't test whether the file is executable;

6175 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed

6196 Problem reported by Stepan Kasal.
6198 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
6200 Fix problems reported by Andreas Buening in:

6207 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
6209 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
6210 "/usr/include", clear ac_x_includes instead of leaving it as "no"
6211 (trivial change). Problem and patch reported by Andrew Church in:
6212 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
6214 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

6219 Also, fix some minor spacing and punctuation bugs.
6221 2004-09-02 Akim Demaille <akim@epita.fr>

6244 Remove ansi2knr.c; nobody uses it.
6245 (ansi2knr.c-url_prefix): Remove.
6246 (cvs-update): Fix test for failure. I don't know why it ever
6247 worked...
6249 * doc/autoconf.texi: Update URLs, some of which went stale.
6250 Use @uref rather than @href.
6252 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
6253 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
6255 * config/config.guess, config/config.sub, config/elisp-comp,
6256 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
6257 doc/fdl.texi, doc/standards.texi: Sync with master copy.
6259 * NEWS, TODO, configure.ac, bin/autoscan.in,
6260 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
6261 doc/install.texi, lib/Autom4te/Configure_ac.pm,

6272 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),

6278 This isn't a complete fix but it's an improvement.
6280 * bin/autoconf.as (autom4te_options): New var.
6281 Use it instead of appending to AUTOM4TE, so that we can allow
6282 spaces in the build directory's absolute name.
6283 * bin/autoheader.in ($autoconf): Allow spaces in file names.
6284 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

6305 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6306 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6307 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
6309 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6311 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
6312 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
6313 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
6314 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
6315 * lib/autom4te.in (Automake-preselections): Preselect
6316 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6318 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6320 * lib/autom4te.in (Automake-preselections): Preselect
6321 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6322 trace them.
6324 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6326 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for

6334 with pdksh, too. Problem reported by Patrick Welche via
6335 Gary V. Vaughan.
6336 * doc/autoconf.texi (Shellology): Note that set -o posix is
6337 useful for pkdsh, too.
6339 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6341 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require

6343 Don't fail if ENV or BASH_ENV is readonly.
6344 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,

6355 * doc/autoconf.texi (File System Conventions): Warn about
6356 names like "aux". Problem reported by Eric Blake.
6358 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6359 by zero instead of array size, so that we can use any arithmetic
6360 constant expression (instead of requiring an integer constant
6361 expression). This allows us to test expressions like DBL_MAX <
6362 LDBL_MAX, which didn't conform to the C standard using the old
6363 method.
6364 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6365 now that we can do floating-point tests at compile time.
6367 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6369 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6370 and LDBL_EPSILON, as the resulting expression isn't an
6371 integer constant expression and violates the C standard.
6372 Problem reported by Nelson H. F. Beebe. Also, check
6373 for "L" suffix, and check that long double doesn't have
6374 worse range or precision than double, that mixed-mode
6375 arithmetic doesn't generate a diagnostic, that double
6376 constants fit in long double.
6378 2004-06-03 Kevin Ryde <user42@zip.com.au>
6380 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6381 malloc(0) and realloc(NULL,size).
6383 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6384 Bob Proulx.
6386 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6388 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6389 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6390 by Jim Meyering.
6392 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6394 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6395 can be rewritten using if-then-else. Suggested by Bruno Haible.
6397 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6399 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6400 Problem reported by Stepan Kasal.
6402 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6404 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6405 change). Patch reported by Ralf Wildenhues in
6406 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6408 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6409 function F exists if the compiler and linker let you compile an
6410 expression like (F != 0). Recent versions of GCC optimize away
6411 the reference to F in that case, since every function address must
6412 be nonzero, so the link succeeds even if F does not exist.
6413 Problem reported by Manu in
6414 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6416 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6417 "Unix". Many uses changed.
6418 (Limitations of Builtins): Explain better why the ! command isn't
6419 portable.
6421 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6423 * lib/autom4te.in (Automake-preselections): Preselect
6424 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6426 2004-05-19 Kevin Ryde <user42@zip.com.au>
6428 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6429 referencing AC_FUNC_STRERROR_R.
6431 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6432 note pessimistic assumption when cross compiling.
6434 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6436 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6437 (until 2004) invoked subcommands with sh -e, contra POSIX.
6438 Reported by Kevin Ryde.
6440 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6442 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6443 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6444 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6445 `test -f " /usr/bin/grep"', which _always_ failed.
6446 (AC_PROG_SED): Ditto bogus PATH fix.
6447 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6448 requires that grep correctly supports _multiple_ `-e' options, rather
6449 than stating only that grep should accept `-e'.
6451 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6453 Port to C99, which requires that 'exit' be declared.
6455 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6456 to ensure that stdlib.h is included.
6457 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6458 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6459 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6460 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6461 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6462 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6463 when using 'exit' in a test; C99 requires that 'exit' be declared.
6465 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6467 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6468 now prefers 'grep' implementations that accept -e.
6469 (Limitations of Usual Tools): Describe problems of traditional
6470 egrep and fgrep with long input lines, and of traditional grep
6471 with -e.
6472 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6473 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6474 All callers changed. Append /usr/xpg4/bin to the PATH, for
6475 Solaris.
6476 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6477 the user with complaints about multiple -e options.
6478 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6479 Define it with AC_PROG_GREP.
6480 * configure.ac (AC_PROG_GREP): Add.
6481 * lib/freeze.mk (GREP): New macro.
6483 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6485 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6486 a possible candidate only after all others fail, rather than
6487 consulting it first. This improves backward compatibility by
6488 better reflecting the way shell selection occurred in previous
6489 versions of Autoconf, and should help to avoid triggering latent
6490 problems in other packages, such as the one in Automake where zsh
6491 is not handled robustly:
6492 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6493 Although it is not Autoconf's responsibility to work around
6494 problems in Automake, it nevertheless makes sense to avoid
6495 introducing unnecessary incompatibilites.
6497 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6498 Gary V. Vaughan <gary@gnu.org>
6500 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6501 how deeply nested we are when a suitable tool is found, set the
6502 ac_path_TOOL_found flag.
6503 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6504 nested we are in this macro. Break out of all 3 nested loops if
6505 ac_path_TOOL_found is set.
6507 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6509 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6510 of the _AS_PATH_WALK loop too if GNU flavor is found.
6512 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6514 * doc/autoconf.texi (Limitations of Make): Update documentation
6515 for `$<'. New entry `Long lines', based on a report from Simon
6516 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6517 paragraph about DJGPP, based on a mail from Richard Dawe.
6519 2004-04-20 Paul Eggert <eggert@twinsun.com>
6521 * tests/c.at (C keywords): Don't assume that GCC supports
6522 "restrict" and "inline", as sufficiently-old GCC versions do not
6523 (also, GCC configured to be in pedantic C89 mode does not).
6524 Problem reported by Sumit Pandya in:
6525 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6527 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6528 consider -g to work if it generates warnings when plain compiles
6529 don't. Problem reported by Braden McDaniel in:
6530 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6532 * doc/autoconf.texi (Slashes): New section, to document a problem
6533 reported by Jim Meyering in:
6534 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6536 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6537 linker output files before linking, to work around IRIX 6 linker bug.
6538 Problem reported by Rainer Orth in:
6539 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6541 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6543 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6544 best tool so far counter rely on the tool path variable name to
6545 avoid checks for one tool being affected by the results of running
6546 the length check on a previous tool.
6548 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6549 match expression argument, as different greps have different
6550 regular expression flavours.
6551 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6552 literals.
6553 (AC_PROG_EGREP): Pass 'EGREP$'.
6554 (AC_PROG_GREP): Pass 'GREP$'.
6556 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6558 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6559 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6561 2004-03-29 Paul Eggert <eggert@twinsun.com>
6563 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6564 Types, Specific Compiler Characteristics, System Services,
6565 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6566 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6567 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6568 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6569 Likewise.
6570 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
6571 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
6572 AC_TYPE_OFF_T): Likewise.
6573 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
6574 Likewise.

6577 pacify libtool 1.5.2. Fix quoting problems in sed command.
6579 2004-03-28 Paul Eggert <eggert@twinsun.com>
6581 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6582 now defines HAVE_DECL_TZNAME if it is declared, when
6583 HAVE_STRUCT_TM_TM_ZONE is not defined.
6584 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6585 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6586 for HAVE_TZNAME.
6588 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
6590 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
6591 superfluous backslashing of quotes (") in sed expressions;
6592 thanks to Paul Eggert.
6594 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6596 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6597 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6598 H. F. Beebe for the bug report.
6600 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6602 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6603 quoted -cmdline argument in Portland Group compiler (bug
6604 reported by Jeffrey J. Barteet).
6606 2004-03-25 Kevin Ryde <user42@zip.com.au>
6608 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to

6630 AC_CHECK_TOOLS.
6631 (Specifying Names): Document the reason for these future
6632 behavioral changes.
6633 * tests/mktests.sh: Do not generate tests for the
6634 new macros.
6635 * NEWS: Document these changes.
6637 * doc/autoconf.texi: Avoid macros with unbraced arguments,

6643 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6644 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6645 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6646 vowel.
6647 (AC_CHECK_ALIGNOF): New macro.
6648 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
6649 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
6650 those for sizeof.
6652 2004-03-03 Paul Eggert <eggert@twinsun.com>
6654 * bin/Makefile.am (edit): Don't use $< in a context where
6655 POSIX doesn't require support for it. Use $@.in instead.
6656 Problem reported by Anthony N. Frasso in
6657 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6658 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
6660 2004-02-23 Gary V. Vaughan <gary@gnu.org>

6688 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6689 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6690 Darwin uses -lcrt2.o and there's little point to cataloging all
6691 the system variants. Partial fix reported by Andreas Waechter in:
6692 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

6706 refer to the correct file.
6707 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
6708 the behavior of the third argument.
6709 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6710 correctly the behavior of the third argument. Document

6721 parameter. Expand _AS_SHELL_FN_SPY.
6722 (AS_INIT_WITH_SHELL_FN): Removed.

6814 2004-01-26 Paul Eggert <eggert@twinsun.com>
6816 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6817 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6818 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6819 not <inttypes.h>. Problem reported by Tim Mooney in
6820 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6821 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6822 Likewise.
6824 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6825 otherwise "make check" fails because it forbids cmp (I guess
6826 because cmp treats files as binary on DOS-like systems).
6828 * tests/mktests.sh: Update copyright date to 2004, since some tests
6829 have changed in 2004.
6831 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6833 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6834 non-truncating sed or gsed program in PATH.
6835 * tests/acprograms.at: Add it.
6836 * doc/autoconf.texi (Particular Programs): Document it.
6837 * NEWS: Updated.
6839 2004-01-15 Paul Eggert <eggert@twinsun.com>
6841 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6842 -std1 disables some useful extensions on Tru64. Problem reported
6843 by N. Lichtmaier in
6844 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6846 2004-01-14 Paul Eggert <eggert@twinsun.com>
6848 * doc/autoconf.texi (Programming in M4sh): Document that
6849 AS_MKDIR_P succeeds if the destination is a symbolic link
6850 to an existing directory.
6851 (Limitations of Usual Tools): Note that mkdir -p might not
6852 succeed on symlinks to directories.
6854 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6856 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6857 * bin/autoheader.in: Grammar fix in message.
6858 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):

6861 2004-01-13 Eric Blake <ebb9@byu.net>
6863 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6864 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6866 2004-01-10 Jim Meyering <jim@meyering.net>
6868 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6870 2004-01-09 Paul Eggert <eggert@twinsun.com>
6872 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6873 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6874 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6875 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6876 AC_COMPILE_IFELSE, since we now assume our caller invokes
6877 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6878 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6879 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6880 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6882 2004-01-07 Paul Eggert <eggert@twinsun.com>
6884 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6885 `"'...'"`, as it's confusing (and I suspect it may not work on
6886 some platforms). The code was incorrect anyway, as it assumed
6887 that \$ evaluated to itself in that context. Reported by
6888 Alexandre Duret-Lutz.
6890 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6892 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6893 and _LT_AC_TAGCONFIG.
6895 2004-01-06 Paul Eggert <eggert@twinsun.com>
6897 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6898 example, and add more examples. Reported by Eric Sunshine.
6900 2004-01-05 Paul Eggert <eggert@twinsun.com>
6902 * doc/autoconf.texi (Limitations of Usual Tools):
6903 Remove warning against "rm -fr" introduced yesterday; it
6904 was a false alarm.
6906 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6907 autoscan, autoupdate, ifnames): Don't use chmod -w.
6908 * lib/Makefile.am (autom4te.cfg): Likewise.
6909 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6910 "chmod -w".
6912 2004-01-04 Paul Eggert <eggert@twinsun.com>
6913 Paolo Bonzini <bonzini@gnu.org>
6915 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6916 by doing lineno substitution only on lines containing "$LINENO".
6918 2004-01-04 Paul Eggert <eggert@twinsun.com>
6920 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6921 Use "rm -f" to remove conftest.sed, not plain "rm".
6922 Bug reported by David Relson in
6923 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6925 * Makefile.am (autom4te-update):
6926 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6927 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6928 * doc/autoconf.texi (Guidelines): Likewise.
6929 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
6930 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.

6932 * lib/autotest/general.m4 (AT_INIT): Likewise.
6933 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
6934 * tests/Makefile.am (clean-local): Likewise.
6935 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6936 srcdir): Likewise.
6937 * doc/autoconf.texi (Limitations of Usual Tools):
6938 Warn against "rm -fr".
6940 2004-01-03 Paul Eggert <eggert@twinsun.com>
6942 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6943 -c -o might not work. From a suggestion by Kevin Ryde.
6944 (C Compiler, Generating Sources, Limitations
6945 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6946 Don't put '-o' after non-options, as POSIX doesn't allow this.
6947 Mention that cc's name might be gcc or c89 or whatever.
6949 2004-01-04 Kevin Ryde <user42@zip.com.au>
6951 * doc/autoconf.texi: Add various further index entries.
6953 2003-12-29 Paul Eggert <eggert@twinsun.com>
6955 * bin/autoreconf.in (autoreconf_current_directory):
6956 Fix typo: mkdir without umask arg.
6958 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6960 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6961 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6962 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6963 explanation clearer.
6965 2003-12-24 Andreas Schwab <schwab@suse.de>
6967 * doc/autoconf.texi (Default Includes): Fix misspelling of
6968 AC_INCLUDES_DEFAULT.

6972 * configure.ac: Test if sh -n works.
6973 * configure: Regenerate.
6974 * tests/atlocal.in: Store the result here.
6975 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6976 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6977 of explicitly testing.
6978 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6979 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6980 * tests/tools.at (Syntax of the shell scripts): Simplify
6981 using AT_CHECK_SHELL_SYNTAX.

6996 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6997 macros.
6998 (AS_SHELL_SANITIZE): Move reinvocation code from
6999 _AS_LINENO_WORKS, use it to find out if shell
7000 functions work.
7001 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
7002 does not work.
7003 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
7004 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
7005 was called.

7015 (&sizes): New.
7016 Use them.

7018 them on the fly.
7020 2003-11-24 Akim Demaille <akim@epita.fr>
7022 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

7063 2003-11-15 Kevin Ryde <user42@zip.com.au>
7065 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
7066 than $target since the latter is not usual, add guidelines on when to
7067 use or not use the system type.
7069 2003-11-12 Derek Price <derek@ximbiot.com>
7071 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

7091 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
7092 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,

7145 than `\n\n', so that `\n\n\n' is valid in warnings.
7146 Reported by Steve Huston.
7148 2003-10-28 Akim Demaille <akim@epita.fr>
7150 * Makefile.cfg (local_updates, executable-update): Tweak to be

7248 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7249 -mGLOB_options_string stuff for Intel ifc, which can cause
7250 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
7251 pattern-matching instead of grep.
7253 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>

7273 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7274 cache variable instead of $G77 to decide whether to include -O2,
7275 since $G77 is specific to Fortran 77.
7277 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7279 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
7280 free" flag. Re-order flags tested into rough order of popularity.
7282 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7284 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7285 arguments so that it can be used with syntax identical to
7286 AC_PROG_F77, and so that we can more easily decide to
7287 remove/deprecate the DIALECT optional argument in the future if it
7288 proves troublesome.
7289 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7290 non-freeform-supporting compilers. Document freeform flags.
7292 2003-10-03 Akim Demaille <akim@epita.fr>
7294 * configure.ac: Look for emacs, not macs.
7295 Reported by Eric Sunshine.
7297 2003-10-03 Akim Demaille <akim@epita.fr>
7299 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
7300 * bin/autoreconf.in (autoreconf_current_directory): Create the
7301 AUX_DIR if needed, for sake of automake --add-missing etc.
7302 Suggested by Alexandre Duret-Lutz.
7304 2003-10-03 Akim Demaille <akim@epita.fr>
7306 * configure.ac: Quotation and formatting changes.
7307 (EMACS): Don't set it if it is not recent enough to support
7308 autoconf-mode.el.
7309 From Eric Sunshine.
7311 2003-10-02 Akim Demaille <akim@epita.fr>
7313 * bin/ifnames.in (&scan_file): Skip C++ comments.

7325 2003-09-30 Paul Eggert <eggert@twinsun.com>
7327 * lib/Autom4te/XFile.pm: Use Errno.
7328 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
7329 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
7331 2003-09-30 Akim Demaille <akim@epita.fr>
7333 * config/announce-gen (&print_news_deltas): Extracted from...
7334 (&print_changelog_deltas): here.
7335 (&news_file): Rename as...
7336 (@news_file): this.

7340 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
7341 have been created when invoking the compiler.

7350 2003-09-28 Paul Eggert <eggert@twinsun.com>
7352 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
7353 Problem reported by Lars J. Aas in
7354 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
7355 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7356 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7357 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7359 2003-09-26 Akim Demaille <akim@epita.fr>
7361 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7362 directory for AC_CONFIG_COMMANDS' first argument exists.
7363 This makes valid the invocation of _AC_SRCPATH that follows.
7364 Reported by Eric Sunshine.
7365 * doc/autoconf.texi (Configuration Commands): Adjust.
7367 2003-09-26 Akim Demaille <akim@epita.fr>
7369 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7370 Reported by Ralf Corsepius.
7372 2003-09-26 Akim Demaille <akim@epita.fr>
7374 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
7375 arguments.
7376 Actually, use AU_ALIAS.
7377 From Bruno Haible.
7379 2003-09-26 Paul Eggert <eggert@twinsun.com>
7381 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
7382 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
7383 Problem reported by Eric Sunshine in:

7386 2003-09-26 Akim Demaille <akim@epita.fr>
7388 The test suite are sometimes assigning timings incorrectly.
7389 Reported by Henk Krus.
7390 Diagnosed by Nicolas Joly.
7392 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7393 AT_help_all.
7394 Instead of making AT_help a sequence of assignments to grow
7395 $at_help_all, just make AT_help_all be the growing contents of
7396 $at_help_all, and make a single assignment in...
7397 (AT_INIT): here.
7398 (at_times_skip): Flip the meaning and rename as...
7399 (at_times_p): this.
7400 (AT_INIT): When summarizing the test that ran, remove
7401 $at_times_file after use, and check it is present before trying to
7402 use it.
7404 2003-09-25 Akim Demaille <akim@epita.fr>
7406 Version 2.57d.
7408 * bin/Makefile.am (edit): Handle '@configure_input@'.
7409 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
7410 (ifnames): chmod -w.
7411 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7412 executables, not bin/ executables! Otherwise all the magic needed
7413 to find non installed files is turned off. This caused a failure
7414 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7415 as found in its environment (sent by tests/autoreconf): pointing
7416 to bin/autom4te that could not find its files.
7417 * tests/mktests.sh: Force the replacement of generated files, for
7418 the sake of "mv" program that are interactive when overwriting a
7419 -w file.
7420 * config/install-sh: Upgrade from CVS Automake.
7422 2003-09-23 Paul Eggert <eggert@twinsun.com>
7424 * doc/autoconf.texi (Limitations of Builtins): Document test -h
7425 versus test -L issues.
7427 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
7428 Paul Eggert <eggert@twinsun.com>
7430 Trivial change to support GCC's configuration procedure.
7431 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
7432 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
7433 about inconsistency if the preprocessor is set to give errors for
7434 any warning.
7435 * doc/autoconf.texi (C Compiler Characteristics): Document this.
7437 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
7439 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
7440 and XFile.pm from Automake.

7451 from masters.
7453 2003-09-12 Akim Demaille <akim@epita.fr>
7455 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
7456 not asm/types.h.
7458 2003-09-11 Akim Demaille <akim@epita.fr>
7460 * doc/autoconf.texi (Header Portability): linux/random.h.
7461 From Peter Hendrickson.
7463 2003-09-10 Akim Demaille <akim@epita.fr>
7465 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
7466 willing to edit the output files.
7468 2003-09-10 Akim Demaille <akim@epita.fr>
7470 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
7471 and AC_FC_FREEFORM.
7472 * tests/mktests.sh: Skip AC_FC_SRCEXT.
7473 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
7475 2003-09-09 Akim Demaille <akim@epita.fr>
7477 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
7478 Reported by Gary Vaughan.

7484 trailing files.
7486 2003-09-07 Paul Eggert <eggert@twinsun.com>
7488 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
7489 Improve the accuracy of the wording about obsolescence.
7490 From a suggestion by Ian Lance Taylor in
7491 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
7493 2003-09-05 Paul Eggert <eggert@twinsun.com>
7495 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
7496 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
7498 2003-09-04 Akim Demaille <akim@epita.fr>
7500 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
7501 AC_FUNC_WAIT3.
7503 2003-09-04 Akim Demaille <akim@epita.fr>
7505 * bin/autom4te.in: Use &fatal where more appropriate than &error.
7506 (freeze): When exiting, use $exit_code.
7507 * lib/autoconf/fortran.m4: Comment changes.
7509 2003-09-04 Akim Demaille <akim@epita.fr>
7511 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7513 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7515 Add support for newer Fortran dialects. The F77 interface is
7516 unchanged, and continues to support Fortran 77. New FC macros
7517 correspond to all the old F77 macros, with output variables FC,
7518 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7519 available dialect, but older dialects can be specified. There are
7520 new macros AC_FC_SRCEXT to set the source extension, and
7521 AC_FC_FREEFORM to accept free-form source files.
7523 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
7524 New macros.
7525 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
7526 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

7528 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

7540 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
7541 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
7542 Rewrite in terms of the above.
7543 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
7544 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
7545 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
7546 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
7548 2003-09-02 Paul Eggert <eggert@twinsun.com>
7550 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
7551 Document problems with timestamp resolution that 'make', 'cp -p', and
7552 'touch -r' have.
7554 2003-08-27 Akim Demaille <akim@epita.fr>
7556 * tests/m4sugar.at (cross_warning): Make sure to enable the
7557 output, so that we can track spurious m4sugar output.
7558 * tests/local.at: Require 2.57.
7559 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7560 are defaulted by AT_CHECK anyway.
7561 Use AT_CHECK_AUTOM4TE.
7562 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7563 missing dnl.
7565 2003-08-27 Akim Demaille <akim@epita.fr>
7567 * bin/autoheader.in: Issue the "Using auxiliary..." message only
7568 when -Wobsolete is set.
7569 Set it on by default.
7570 Suggested by Klee Dienes.
7572 2003-08-27 Akim Demaille <akim@epita.fr>

7581 after AC_OUTPUT.
7583 2003-08-25 Akim Demaille <akim@epita.fr>
7585 * config/announce-gen, GNUmakefile, Makefile.maint: Update from

7616 Output stack traces in warnings.
7618 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
7619 Replace the former...
7620 (m4_warn): Pass the call stack to _m4_warn.
7621 * bin/autom4te.in: Adjust to output the call stack.
7622 * tests/m4sugar.at (m4@&t@_warn): Adjust.
7624 2003-08-22 Akim Demaille <akim@epita.fr>
7626 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
7627 * bin/autom4te.in: Adjust.
7629 2003-08-21 Akim Demaille <akim@epita.fr>
7631 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7632 (&verbose): Remove.
7633 (&getopt): Adjust the note and verb channels, depending upon
7634 --verbose.
7635 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
7636 * bin/autoupdate.in: Adjust.
7637 Use &verb, not &verbose.
7639 2003-08-21 Akim Demaille <akim@epita.fr>
7641 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7642 &parse_WARNINGS.
7643 ($help): Use Autom4te::ChannelDefs::usage.
7644 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7645 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7647 2003-08-21 Akim Demaille <akim@epita.fr>
7649 First stab at preserving warnings between calls to autom4te,
7650 including when the cache is used.
7652 There are still several issues: (i) there are too many runs of m4
7653 (one for include, one for warnings, and some more), (ii) warnings
7654 spreading on several lines are not handled gracefully, (iii) the
7655 code meant to have the call stack display for errors does not work
7656 (its handling should move from m4 to autom4te).
7658 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7659 Use them.
7660 (@preselect): Add m4_warn.
7661 ($exit_status): Remove, use $exit_code.
7662 ($help): Use Autom4te::ChannelDefs::usage.
7663 (&handle_m4): No longer define the m4_warnings.
7664 At each run, extract and report the warnings.
7665 Always cache the result, including if the exit status is on
7666 failure, since if nothing changes, we should result in the same
7667 failure, hence we can use the cache.
7668 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7669 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7670 Remove.
7671 (m4_warn): Redefine as a do-nothing: it is its invocation that
7672 matters, as warnings are now reported via traces.
7673 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7674 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7675 the latter reveals calls to the former.
7677 Adjust the tests.
7679 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7681 2003-08-21 Akim Demaille <akim@epita.fr>
7683 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7684 Use them.
7686 2003-08-21 Akim Demaille <akim@epita.fr>
7688 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7689 forward order.
7690 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7691 (&parse_warnings): Accept a list of warning requests.
7692 (&usage): Return a string, not a side effect.
7693 (cross): New warning category.
7695 2003-08-21 Akim Demaille <akim@epita.fr>
7697 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7698 (&require_configure_ac): Accept an optional directory argument.
7699 ($configure_ac): Remove.
7700 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7701 (&catfile): Remove.
7702 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7703 * bin/autoscan.in: Adjust.
7705 2003-08-20 Akim Demaille <akim@epita.fr>
7707 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7708 Reported by Alexandre Duret-Lutz.
7710 2003-08-20 Akim Demaille <akim@epita.fr>
7712 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7713 * bin/autom4te: Adjust.
7714 In particular, be Autoconf tools are really silent when properly
7715 working, bind the verbosity of the 'note' channel to $verbose.
7716 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7717 (&xsystem, &contents): Remove, since they are exported by...
7718 * lib/Autom4te/FileUtils.pm: this.
7719 More perldoc.
7720 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7721 * lib/Autom4te/FileUtils.pm: here.
7723 2003-08-20 Akim Demaille <akim@epita.fr>
7725 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7726 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
7727 from CVS Automake.

7732 (autom4te-update): New.
7733 * Makefile.cfg (update): Bind autom4te-update.

7737 * lib/autotest/general.m4: Comment various HELP_* diversions.
7738 (PARSE_ARGS_BEGIN): New section for option parsing related
7739 initialization.

7745 * config/announce-gen, Makefile.cfg: New.
7746 * Makefile.am: Adjust.
7747 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
7749 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7751 * lib/autom4te.in (Automake-preselections): Preselect

7757 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
7758 (Autoconf-without-aclocal-m4): ... this new language.
7759 * doc/autoconf.texi (autom4te Invocation): Mention
7760 Autoconf-without-aclocal-m4.
7762 2003-08-18 Derek Price <derek@ximbiot.com>
7764 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
7765 RUN-IF-PASS optional arguments.
7767 2003-08-18 Derek Price <derek@ximbiot.com>

7774 STDOUT & STDERR arguments.
7776 2003-08-14 Derek Price <derek@ximbiot.com>
7778 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7779 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7780 shorter column three. Add DESCRIPTION to log file content.
7782 2003-08-13 Derek Price <derek@ximbiot.com>
7784 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7785 output.
7787 2003-08-12 Derek Price <derek@ximbiot.com>
7789 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7790 (AT_CHECK_NOESCAPE): Move core functionality to...
7791 (_AT_CHECK): ...this new macro.
7793 2003-08-07 Derek Price <derek@ximbiot.com>
7795 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7796 (AT_CHECK_NOESCAPE): ...to this new macro.
7798 2003-07-31 Paul Eggert <eggert@twinsun.com>
7800 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7801 in Bash 2.01. Problem reported by Brian Gough in
7802 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7804 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7806 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7807 -lcrt1.o, for OS X. (trivial change)
7809 2003-07-07 Paul Eggert <eggert@twinsun.com>
7811 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7812 inside '#ifndef __cplusplus'. Problem reported by
7813 Bob Friesenhahn.
7815 2003-07-06 Bill Clarke <llib@computer.org>
7817 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7818 'long', not 'int', for benefit of Sun's recent C++ compilers
7819 (trivial change). See:
7820 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7821 (This really should be 'intptr_t', not 'long', but that would
7822 take more work.)
7824 2003-06-25 Akim Demaille <akim@epita.fr>
7826 * lib/Makefile.am (autom4te.cfg): Make it read only.
7827 Depend on Makefile since it contains substitutions.
7828 From Paolo Bonzini.
7829 * lib/autom4te.in (args): Add local.at? for Autotest args.
7830 This change was made on autom4te.cfg which is generated.
7831 Reported by Raja R. Harinath.
7833 2003-06-25 Akim Demaille <akim@epita.fr>
7835 * doc/autoconf.texi (Header Portability): sys/mount.h.
7836 From Gareth McCaughan.
7838 2003-06-23 Akim Demaille <akim@epita.fr>
7840 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7841 not all of them. This fixes 1. the fact that when testing
7842 Autoconf there are many many config.log, 2. the incorrect use of
7843 top_srcdir to find config.log.
7844 Don't mix the detailed output of failed test with the summary of
7845 failures. Rather, append detailed log afterwards.
7847 2003-06-23 Akim Demaille <akim@epita.fr>
7849 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7850 always run: output config.log on $at_group_log.
7852 2003-06-23 Akim Demaille <akim@epita.fr>
7854 * tests/torture.at (#define header templates): Don't use quotes in
7855 C++ comments as it puzzles Emacs' sh font-lock-mode.
7857 2003-06-23 Akim Demaille <akim@epita.fr>
7859 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7860 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7861 * tests/atspecific.m4: Rename as...
7862 * tests/local.at: This.
7863 * tests/suite.at: Move the globals into...
7864 * tests/local.at: here.
7865 * tests/Makefile.am: Adjust.
7866 * doc/autoconf.texi (testsuite Scripts): Adjust.
7868 2003-06-21 Kevin Ryde <user42@zip.com.au>
7870 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7871 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7872 ensuring we add -std1 for full-ANSI.
7874 * doc/autoconf.texi (hdrindex): New macro.
7875 Add index entries for portability of various standard header files.
7877 2003-06-20 Akim Demaille <akim@epita.fr>
7879 * configure.ac: Bump to 2.57b.
7881 2003-06-20 Akim Demaille <akim@epita.fr>
7883 Version 2.57a.
7885 2003-06-20 Akim Demaille <akim@epita.fr>
7887 * bin/autom4te.in: Don't rely on $HOME being defined.
7888 Reported by Marc Espie as PR/233.
7890 2003-06-20 Akim Demaille <akim@epita.fr>
7892 * lib/autotest/general.m4: Use at_times_file only if used.
7893 From Nicolas Joly.
7895 2003-06-20 Akim Demaille <akim@epita.fr>
7897 * config/config.guess, config/config.sub, config/elisp-comp,
7898 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7899 Update from masters.
7901 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7903 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7904 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7905 (TEST_SCRIPT): New diversion.
7906 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7907 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7908 (AT_INIT): Support for expected failures.
7910 2003-06-02 Akim Demaille <akim@epita.fr>
7912 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7913 changes.
7914 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7915 Autoconf nor Automake.
7916 (&contents): New, from Automake.
7917 PODify.
7919 2003-05-28 Paul Eggert <eggert@twinsun.com>
7921 * NEWS, doc/autoconf.texi (Particular Functions),
7922 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7923 is the inverse of localtime.
7925 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7927 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7928 (handle_exec_errors): New function. Work around $! being
7929 altered by WEXITSTATUS.
7930 (xqx, xsystem): Use handle_exec_errors.
7932 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7934 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7935 Do not call `_exit()', simply modify `$?'.
7936 (xsystem): Reset $! before running system, and check it afterward.
7937 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7938 63 for version mismatches.
7940 2003-05-23 Akim Demaille <akim@epita.fr>
7942 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7943 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7944 the middle of a line).
7945 * lib/m4sugar/m4sugar.m4: Likewise.
7946 Remove useless spaces in comments.
7948 2003-05-23 Akim Demaille <akim@epita.fr>
7950 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7951 exit 63, so that we (or Automake's "missing") can tell the
7952 difference with a plain failure.
7953 * doc/autoconf.texi (Notices): Adjust.
7955 2003-05-23 Akim Demaille <akim@epita.fr>
7957 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7958 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7959 White spaces cleanup.
7961 2003-05-22 Jim Meyering <jim@meyering.net>
7962 Paul Eggert <eggert@twinsun.com>
7964 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7965 Remove `#include <stdlib.h>' from the list; we should never
7966 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7967 resulting namespace pollution would cause other tests to fail.
7968 Configure scripts run with some older versions of g++ and HP's
7969 aCC would fail due to such an #include. Problems reported by
7970 Matthew Mueller in <http://bugs.debian.org/120704> and by
7971 Keith Bostic in
7972 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7973 In the test, use the test declaration before including <stdlib.h>,
7974 as that's closer to how it'll be used.
7976 2003-05-23 Akim Demaille <akim@epita.fr>
7978 * doc/autoconf.texi (Header Portability): ucred.h.
7979 From Ian Redfern.
7981 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7983 Overhaul Autotest's logging: generate separate log files
7984 in testsuite.dir/NNN/testsuite.log, and append them to
7985 testsuite.log instead of re-running the test verbosely.
7987 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7988 file descriptor, write 0 to at_status_file instead of setting
7989 at_status=0, initialize some new variables (at_status_file,
7990 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7991 to rerun the tests, instead append the at_group_log to the
7992 at_suite_log when a test fails.
7993 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7994 with the AS_MESSAGE_LOG_FD redirected to stdout.
7995 (AT_CLEANUP): save the output status in $at_status_file
7996 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7997 its original place.
7998 (AT_CHECK): since tests are run with a redirected stdout,
7999 and used to be re-run in verbose mode, turn some $at_verbose
8000 into echo, and don't redirect the output of testing stdout
8001 and stderr.
8003 * lib/autotest/autoconf.texi (testsuite Scripts): Update
8004 the name of the debugging directory and information about
8005 its contents.
8007 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8009 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
8010 parameter.
8012 2003-05-22 Akim Demaille <akim@epita.fr>
8014 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
8015 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
8016 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

8032 Whitespace clean up.
8033 Suggested by Jim Meyering.
8035 2003-05-22 Akim Demaille <akim@epita.fr>
8037 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
8038 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
8039 Reported by Jim Meyering.
8041 2003-05-22 Akim Demaille <akim@epita.fr>
8043 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

8065 2003-05-19 Paul Eggert <eggert@twinsun.com>
8067 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:

8074 AC_CHECK_HEADERS_NEW): New tests.
8076 2003-05-17 Akim Demaille <akim@epita.fr>
8078 * lib/autoconf/functions.m4: Use the default includes so that
8079 memcmp be declared before being tested.
8080 Reported by Sander Niemeijer.
8081 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
8082 * doc/autoconf.texi (Default Includes): Document
8083 AC_INCLUDES_DEFAULT.
8085 2003-05-17 Akim Demaille <akim@epita.fr>
8087 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
8088 * doc/autoconf.texi (Obsolete Macros): Adjust.
8089 Reported by Werner LEMBERG and Debian Bug 190886.
8091 2003-05-16 Akim Demaille <akim@epita.fr>
8093 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
8094 user name space clashes.
8095 Reported by Bruno Haible.
8097 2003-05-16 Akim Demaille <akim@epita.fr>
8099 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
8100 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
8101 them uniform, and more robust to Perl special characters.
8102 Reported by Martin Mokrejs.
8104 2003-05-14 Akim Demaille <akim@epita.fr>
8106 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
8108 2003-05-14 Akim Demaille <akim@epita.fr>
8110 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

8115 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
8116 message.
8117 From Matthias Andree.
8119 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>

8122 and truncate.
8124 2003-05-06 Akim Demaille <akim@epita.fr>
8126 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
8127 longer updates aclocal.m4 if useless, (ii) if a file m4_included
8128 by aclocal.m4 is changed it might require the importing of another
8129 m4 extension file, i.e., aclocal must be run.
8131 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
8132 (&parse_args): Use --force with aclocal if required and supported.
8133 (&autoreconf_current_directory): Use &run_aclocal.
8135 2003-05-06 Akim Demaille <akim@epita.fr>
8137 Lock autom4te's cache.
8139 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
8140 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
8141 argument instead of a file name, so that the request file remains
8142 open during the whole autom4te run.
8143 ($icache_file): New.
8144 (&freeze): Lock the $icache_file.
8146 2003-04-29 Derek Price <derek@ximbiot.com>
8148 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
8149 seperator with m4_append_uniq(). It doesn't work.
8150 (AT_CLEANUP): Add `;' to end of at_help_all.
8151 (AT_INIT): Allow --keywords to be specified more than once. When
8152 grepping $at_help_all for keywords, use the field and keyword
8153 seperators to ensure a complete keyword match. Alter at_prev handling
8154 to support the new --keywords behavior.
8156 2003-04-27 Karl Berry <karl@freefriends.org>
8158 * doc/autoconf.texi: Make the dir entries in the autoconf manual
8159 align better with others. I also made some of the individual
8160 entries on one line, for brevity and to make it easier for me to
8161 sort my dir-example file in the Texinfo distribution :).
8163 2003-04-12 Jim Meyering <jim@meyering.net>
8165 * NEWS: Mention the new macro.
8166 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.
8167 * doc/autoconf.texi (C Compiler): Describe AC_C_RESTRICT.
8168 * tests/c.at: Test AC_C_RESTRICT.

8181 2003-04-08 Akim Demaille <akim@epita.fr>
8183 * doc/autoconf.texi (Particular Headers): Some about sys/socket.h,

8196 2003-04-01 Akim Demaille <akim@epita.fr>
8198 * doc/autoconf.texi (ac, at, ms): Rename these indexes as...
8199 (AC, AT, MS): these.
8200 (shortindexflag, @acindex, @ahindex, @asindex, @atindex, @msindex):
8201 New.
8202 Use them.
8203 * doc/Makefile.am (CLEANFILES): Adjust.
8204 (TEXI2DVI): Make it --batch.
8206 2003-03-31 Derek Price <derek@ximbiot.com>
8208 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
8209 which removed the main loop.
8210 Thanks to Akim Demaille.
8212 2003-03-29 Akim Demaille <akim@epita.fr>
8214 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
8215 that starts a GUI.
8216 From Ilya Zakharevich.
8218 2003-03-29 Akim Demaille <akim@epita.fr>
8220 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
8221 documentation to read is Autoconf's.
8222 Suggested by Paul Eggert.
8224 2003-03-28 Akim Demaille <akim@epita.fr>
8226 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
8227 reading the section "Present But Cannot Be Compiled" when the
8228 header causes problems.
8230 2003-03-28 Akim Demaille <akim@epita.fr>
8232 * tests/torture.at (Configuring subdirectories): Require aclocal
8233 1.4, otherwise the test fails, as it does support configure.ac.
8234 This fixes the "test 40 failed" bug reports.
8236 2003-03-28 Akim Demaille <akim@epita.fr>
8238 * doc/autoconf.texi (C Compiler): `#line' portability.
8239 From Paul Eggert and Nelson H. F. Beebe.

8325 to cope with DOS-style absolute paths, when constructing
8326 ${ac_make}.
8328 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
8329 When constructing paths with IFS=:, quote the path. If we're
8330 constructing a DOS-style absolute path, we don't want to split it
8331 on the colon.
8333 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
8334 in description.

8348 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
8349 to fix a mismatch between example and discussion.

8354 format starting with "-".
8356 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8358 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8359 is not portable inside Makefile.
8361 2003-02-20 Akim Demaille <akim@epita.fr>
8363 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8364 compiler says yeah, but preproc says nope, compiler is right.
8365 Conversely, prompt the reader to send a bug report to the
8366 maintainers of the package, not of Autoconf.
8368 2003-02-20 Klee Dienes <kdienes@apple.com>

8381 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8382 innocuous variant befor including <limits.h> or <assert.h>. This
8383 works around a bug reported by Albert Chin: HP-UX 11i
8384 (and earlier versions) have a <limits.h> that declares
8385 gettimeofday and many other functions.
8387 2002-12-03 Paul Eggert <eggert@twinsun.com>
8389 Version 2.57.
8391 * NEWS, configure.ac: Update version.
8393 * doc/fdl.texi: Upgrade to FDL version 1.2.
8395 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8396 nontrivially in main's body, so that f's external declaration is
8397 not optimized away in AIX. This should fix the bug reported by
8398 Martin Frydl in
8399 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8401 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8402 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8403 defined, to support freestanding compilers. This should fix the
8404 bug reported by Momchil Velkov in
8405 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8407 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8408 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

8421 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
8423 2002-11-15 Akim Demaille <akim@epita.fr>

8430 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
8431 * configure.ac (AM_INIT_AUTOMAKE): here.
8432 Require 1.7.1.
8434 2002-11-14 Akim Demaille <akim@epita.fr>
8436 Version 2.55.
8438 * config/config.guess, config/config.sub, config/install-sh:
8439 Update from masters.
8441 2002-11-14 Akim Demaille <akim@epita.fr>
8443 * Makefile.maint: Sync with Bison, i.e.:
8444 (po-check): Scan .l and .y files instead of the
8445 .c and the .h files that they generate. This fixes the bug
8446 reported by Tim Van Holder in:
8447 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8448 Look for N_ as well as for _. Try to avoid matching #define for
8449 N_ and _.
8450 From Paul Eggert.
8452 2002-11-14 Akim Demaille <akim@epita.fr>
8454 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8455 From Paul Eggert and Albert Chin-A-Young.
8457 2002-11-14 Akim Demaille <akim@epita.fr>

8460 From Paul Eggert and Albert Chin-A-Young.
8462 2002-11-14 Kevin Ryde <user42@zip.com.au>
8464 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8465 than assigning in main, to avoid HP cc +O3 optimizing it away.
8467 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8469 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8470 option. Process --recheck after parsing all options. Pass -q
8471 option to configure on --recheck.
8472 (AC_OUTPUT): Pass -q from configure to config.status.
8473 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8474 arguments to record.

8476 config.status -q option.
8478 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

8481 Makefile.in if Makefile.am exists.

8500 * tests/torture.at (Configuring subdirectories): Don't use grep
8501 -w.
8502 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
8503 Reported by Ezra Peisach.
8505 2002-11-05 Akim Demaille <akim@epita.fr>
8507 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8508 Remove.
8509 We _have_ to stop using the old compatibility scheme that tried to
8510 avoid useless backslashes because Libtool 1.4.3 contains a
8511 AC_DEFINE([error_t], [int],
8512 [Define to a type to use for \`error_t' if it is not
8513 otherwise available.])
8514 We _have_ to quote the single quote and backslashes with \. The
8515 old compatibility scheme saw that ` was backslashed, and therefore
8516 did not quote the single quote. Hence before this patch, Autoconf
8517 was not compatible with Libtool.
8519 2002-11-04 Paul Eggert <eggert@twinsun.com>
8521 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8526 2002-11-04 Akim Demaille <akim@epita.fr>
8528 Version 2.54c.
8530 * Makefile.maint (update, cvs-update, po-update, do-po-update):

8536 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
8537 from...
8538 (&autoreconf): here.
8539 ($help, $make, &parse_args, &autoreconf_current_directory):
8540 Support -m/--make.
8541 * doc/autoconf.texi (autoreconf Invocation): Adjust.

8557 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
8559 2002-10-31 Akim Demaille <akim@epita.fr>
8561 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
8562 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8563 Make variable, not a shell variable.
8564 Suggested by Bruno Haible.
8566 2002-10-31 Akim Demaille <akim@epita.fr>
8568 * bin/autom4te.in (load_configuration): Reject #args out of any
8569 language.
8571 2002-10-31 Akim Demaille <akim@epita.fr>
8573 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
8574 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

8576 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

8585 Suggested by Tim van Holder.
8587 2002-10-29 Paul Eggert <eggert@twinsun.com>
8589 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
8590 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
8591 Problem reported by Bruno Haible.
8593 2002-10-29 Akim Demaille <akim@epita.fr>
8595 * doc/autoconf.texi (Header Templates): Put also in words what the
8596 pictures says to assist free style readers.
8597 (Customizing autom4te): s/--cache=/--cache /.
8599 2002-10-29 Akim Demaille <akim@epita.fr>
8601 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
8602 sys/wait.h.
8603 sparc_address_test returns void.
8604 Use it with an argument, as prototyped.
8605 From Bruno Haible.
8607 2002-10-29 Akim Demaille <akim@epita.fr>

8849 2002-10-22 Akim Demaille <akim@epita.fr>
8851 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

8853 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
8854 Quote for Perl '' strings, not "".
8855 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8856 strings.
8858 2002-10-22 Akim Demaille <akim@epita.fr>
8860 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

8908 Reported by Alexandre Duret-Lutz.
8910 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8911 to frozen files in @ARGV, as @ARGV must remain being a list of

8914 (&freeze): Use &error.
8915 (&up_to_date): If a file that was included according to the cache
8916 is no longer there, then the output is out dated.

8918 --force is given.
8919 * tests/tools.at (autom4te cache): New.

8928 that error messages can be easily located, and use GNU Make
8929 format, so that Emacs' compile mode understands us.
8930 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8931 if some file was changed instead of `print'.
8932 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
8933 (&parse_args): Remove the dead options.

8966 file name to enable parallel executions.
8967 From Sam Varshavchik.
8969 2002-10-08 Akim Demaille <akim@epita.fr>
8971 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8972 aclocal invocation, as Gettext macros might not be visible to
8973 aclocal.
8974 Instead of blindly running autopoint, scan configure.ac (not the
8975 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8976 Reported by Paul D. Smith.
8978 2002-10-08 Paul Eggert <eggert@twinsun.com>
8980 Work around problems found when POSIXLY_CORRECT=1 is set.
8981 None of this seems to have anything to do with POSIX, really,
8982 but it's how Perl getopt works.
8983 * bin/autom4te.in (parse_args): Configure GetOpt with
8984 "permute", too.
8985 * doc/autoconf.texi (Invoking autom4te):
8986 --warning -> --warnings.

9006 2002-09-28 Akim Demaille <akim@epita.fr>
9008 * tests/torture.at (Configuring subdirectories): Be robust to
9009 users who use config.site to require for a cache: in this case,
9010 the two last configure runs, using two different sets of
9011 arguments, trigger a legitimate error.
9013 2002-09-28 Akim Demaille <akim@epita.fr>

9032 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
9033 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
9034 * lib/autoconf/programs.m4: here.

9046 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.

9048 tests/autom4te itself.
9049 * lib/autoscan/Makefile.am: Include freeze.mk.
9050 (autoscan.list): New target --this file is no longer a source.
9051 (autoscan.pre): New file.

9058 tracking changes in autoscan.list.
9059 * lib/autoscan/autoscan.list (function): Strip comments, sort.
9061 2002-09-28 Akim Demaille <akim@epita.fr>

9074 `functions' line is now prefixed with `function:'.
9075 * bin/autoscan.in (&init_tables): Adjust.
9077 2002-09-28 Akim Demaille <akim@epita.fr>
9079 From now on, autoscan files must always map a macro name to a
9080 word: there is no `default' macro for autoscan.
9082 * bin/autoscan.in (&init_tables): Reject entries with no macro at
9083 all.
9084 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
9085 explicit.
9087 2002-09-28 Akim Demaille <akim@epita.fr>
9089 * bin/autoscan.in (%c_keywords): Remove.

9123 * doc/autoconf.texi (autoreconf Invocation): Likewise.
9125 2002-09-26 Akim Demaille <akim@epita.fr>
9127 Single suffix rules and seperated dependencies are not portable.

9175 Suggested by Guido Draheim.
9177 2002-09-13 Akim Demaille <akim@epita.fr>

9185 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
9186 the lists.

9202 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but

9204 is obsolescent.

9208 * doc/autoconf.texi (Questions): Rename as...

9227 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9228 Reported by Ralf Corsepius.

9235 looking for a replacement file.
9236 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9237 directory is relative.
9238 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9239 directory definition.
9240 Reported by Andreas Schwab and Jim Meyering.
9242 2002-09-06 Akim Demaille <akim@epita.fr>
9244 * doc/autoconf.texi (Setting Output Variables): Clarify what
9245 precious variables are.
9246 Suggested by Pontus Skoeld.
9248 2002-09-05 Akim Demaille <akim@epita.fr>
9250 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9251 (ifnames, autoscan, autom4te): Since we don't only depend on
9252 configure.ac variables (such as VERSION etc.), but also on prefix
9253 and so forth, depend on Makefile, not configure.ac.
9254 Reported by Alexandre Duret-Lutz.
9255 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9257 2002-09-05 Kevin Ryde <user42@zip.com.au>
9259 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9260 doesn't seem to be confined to ia64, just say "some versions".
9262 2002-09-04 Akim Demaille <akim@epita.fr>
9264 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9265 Automake 1.6c.
9266 * Makefile.am (maintainer-clean-local): Remove.
9267 (MAINTAINERCLEANFILES): Remove COPYING.
9269 2002-09-03 Paul Eggert <eggert@twinsun.com>
9271 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9272 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9273 Brinkmann.
9275 2002-09-03 Akim Demaille <akim@epita.fr>
9277 * configure.ac: Bump to 2.53d.
9278 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9279 as of today, on Automake's team suggestion.
9281 2002-09-03 Akim Demaille <akim@epita.fr>
9283 Version 2.53c.
9285 2002-09-02 Akim Demaille <akim@epita.fr>
9287 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9288 SITE_MACRO_DIR.
9289 * configure.ac: Disable SITE_MACRO_DIR.
9291 2002-09-02 Jim Meyering <meyering@lucent.com>
9293 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9294 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9295 Also, tweak grammar: s/make sure to/be sure to/.
9297 2002-09-02 Paul Eggert <eggert@twinsun.com>
9299 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9300 directory names are generally preferable to physical names.
9302 2002-09-02 Akim Demaille <akim@epita.fr>
9304 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9305 Reported by Raja R. Harinath.
9306 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9307 * bin/autoupdate.in: Use error instead of die.
9309 2002-09-01 Paul Eggert <eggert@twinsun.com>
9311 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9312 ordinary shell concatenation rather than echo+tr+sed command that
9313 runs afoul of a long-line-related sed bug in Solaris 8.
9315 * bin/autoheader.in (parse_args): --warning -> --warnings.
9317 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9318 stdout, as traditional "ls" does.
9319 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9320 _AC_COMPILER_EXEEXT_O): Likewise.
9321 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9323 * bin/autoconf.as: Add --prepend-include option. This patch was
9324 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9325 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9327 * bin/autoconf.in, configure: Regenerate.
9329 * doc/autoconf.texi (Special Shell Variables): Mention
9330 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9332 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9333 MAILPATH and set PS1, PS2, PS4 to default values, to work
9334 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9335 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9336 the Autoconf documentation specifies; fall back to "unset" only if
9337 this fails. Use a shell for-loop for this rather than an m4 loop,
9338 to shorten the output script.
9340 2002-08-30 Paul Eggert <eggert@twinsun.com>
9342 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9343 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9344 for the CDPATH problem. Document PWD.
9345 (Limitations of Builtins): Document the problem that "cd $foo" and
9346 "ls $foo" may refer to different directories in shells conforming
9347 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9348 example, since the old example is now out of date.
9350 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9351 FOO" and "ls FOO" talk about different directories; this catches
9352 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9353 spaghetti.
9355 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9356 of rolling our own unset.
9357 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9358 in practice we needn't worry about CDPATH if unset doesn't work.
9360 * Makefile.in, aclocal.m4, bin/Makefile.in,
9361 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9362 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9363 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9364 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9365 tests/Makefile.in: Regenerate with Automake 1.6.3.
9367 * config/config.guess, config/config.sub, config/mkinstalldirs:
9368 Update.
9370 * configure: Regenerate with self.
9372 2002-08-30 Kevin Ryde <user42@zip.com.au>
9374 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9375 default output.
9377 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9379 * bin/autom4te.in (Request::load): Correctly test for "do" read
9380 failure.
9382 2002-08-29 Akim Demaille <akim@epita.fr>
9384 * lib/Autom4te/General.pm (&xqx): New.
9385 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9386 hand, which is not portable.
9387 (&error): New.
9388 * bin/autom4te.in: Use them.
9389 Use &error instead of die.
9390 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9391 Adjust.
9393 2002-08-17 Paul Eggert <eggert@twinsun.com>
9395 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9396 default list of compilers to try, since it was long ago superseded
9397 by the ksh fc builtin. Suggested by Steven G. Johnson.
9399 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9401 * doc/autoconf.texi (Invoking autom4te): End the option table,
9402 fixing a bug introduced by the previous patch.
9403 (Limitations of Make): Add a 'target lookup' subentry in the
9404 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9406 2002-07-29 Mark D. Roth <roth@feep.net>
9408 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9409 options and use $AUTOM4TE_PATH.
9410 * doc/autoconf.texi: Remove documentation of autom4te
9411 --include-envvar and --site-macro-subdir options and document
9412 use of $AUTOM4TE_PATH.
9413 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9414 arguments from each language section.
9416 2002-07-29 Paul Eggert <eggert@twinsun.com>
9418 * doc/install.texi: Include copyright symbol in copyright notice.
9420 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9421 Replace with:
9422 (AM_MAKEINFOFLAGS): New macro.
9423 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9424 * Makefile.am (INSTALL): Use the new macros.
9425 Use -o rather than --output, since "missing" does not grok --output.
9427 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9429 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9430 comments do not always work. Never trust the exit status of
9431 `make -k'.
9433 2002-07-24 Kevin Ryde <user42@zip.com.au>
9435 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9436 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9438 2002-07-23 Paul Eggert <eggert@twinsun.com>
9440 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9441 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9442 apparently treats PATH="nonexistent" as if it contained ".".
9443 Bug reported by Stefan `Sec' Zehl.
9445 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9447 * doc/autoconf.texi (Limitations of Make): Mention the special
9448 handling of the obj/ directory by BSD make.

9468 2002-07-18 Akim Demaille <akim@epita.fr>
9470 * config/config.guess, config/config.sub: Update.
9472 2002-07-18 Akim Demaille <akim@epita.fr>

9500 * lib/Autom4te/General.pm (find_file): Browse the directories in

9604 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9606 * bin/autom4te.in ($cache): Don't define using `$me', the name
9607 of the cache should not depend on the name under which autom4te
9608 was installed.
9610 2002-06-07 Akim Demaille <akim@epita.fr>
9612 * tests/tools.at (autoconf: forbidden tokens, basic)

9712 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9713 This improves on an earlier suggestion by H. Peter Anvin.
9715 2002-05-16 Paul Eggert <eggert@twinsun.com>
9717 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9718 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9719 Both macros now accept an optional source-dir arg.
9720 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9722 * NEWS: Document this.
9723 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9725 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9726 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9727 not for GNU extensions; this undoes part of the 2000-11-03 change,
9728 reverting to 2.13-compatible behavior.
9729 Add new optional argument DIR.
9730 (AC_FUNC_FNMATCH_GNU): New macro.
9732 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9734 2002-05-08 Paul Eggert <eggert@twinsun.com>
9736 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9737 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9738 and it causes a 'test' syntax error if it fails.
9739 Bug reported by Stephen Gildea.
9741 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9742 If prototypes are supported, use them to check this at compile-time,
9743 instead of trying to check it at run-time. If we must do a run-time
9744 check, assume that setvbuf is standard when cross-compiling, as
9745 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9746 Bug reported by Paul D. Smith.
9748 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9749 argument specifying location of getloadavg.c. This removes a
9750 FIXME. This idea was taken from Jim Meyering's implementation in
9751 textutils.
9752 * doc/autoconf.texi (Particular Functions): Document this.
9753 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9754 that's what the code does; this fixes a bug reported by
9755 Paul D. Smith.
9757 2002-05-03 Akim Demaille <akim@epita.fr>
9759 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9760 autopoint instead of gettextize.
9761 ($uses_alocal): Rename as...
9762 ($uses_aclocal): this.
9763 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9764 Suggested by Bruno Haible.
9766 2002-05-03 Akim Demaille <akim@epita.fr>
9768 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9770 2002-04-29 Paul Eggert <eggert@twinsun.com>
9772 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9773 files to be 1 second older; just set them to be the same time.
9774 Also, sleep 1 second after the first aclocal, to work around
9775 problems with sub-second time stamps on the input files.
9777 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9779 * doc/autoconf.texi: Mention "set -e -x" lossage
9780 under node "Limitations of Builtins".
9782 2002-04-29 Akim Demaille <akim@epita.fr>
9784 * doc/install.texi: Better wording for setting variables when
9785 running configure.
9786 From Christian Cornelssen.
9788 2002-04-29 Akim Demaille <akim@epita.fr>
9790 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9791 of lack of $LINENO support, then the test will compare the $LINENO
9792 in testsuite vs. the lineno in the test file. This is wrong, of
9793 course.
9794 Be sure to protect it.
9795 Reported by Patrick Welche.
9797 2002-04-25 Akim Demaille <akim@epita.fr>
9799 * doc/autoconf.texi (Obsolete Macros): Typo.
9800 Reported by Vladimir Volovich.
9802 2002-04-25 Akim Demaille <akim@epita.fr>
9804 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9805 than some of the input files, hence, on the second run of aclocal,
9806 if some of its input are younger, make them older.
9807 Suggested by Paul Eggert.
9809 2002-04-25 Akim Demaille <akim@epita.fr>
9811 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9812 Thanks to Paul Eggert.
9814 2002-04-25 Akim Demaille <akim@epita.fr>
9816 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9817 and ac_subst_vars be sh variables containing the list of
9818 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9819 DEFAULT diversion.
9820 (_AC_INIT_PREPARE): Use them to log them.
9821 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9822 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9823 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9824 _AC_SUBST_FILES and _AC_SUBST_VARS.
9825 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9827 2002-04-24 Akim Demaille <akim@epita.fr>
9829 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9830 autoheader, so that automake does not complain about a missing
9831 config.h.in that was to be created.
9833 2002-04-23 Akim Demaille <akim@epita.fr>
9835 * bin/autoheader.in (parse_args): --warning takes an argument.
9836 Fixes PR/220.
9838 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9840 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
9841 and bb.out when cleaning up.
9843 2002-04-22 Akim Demaille <akim@epita.fr>
9845 Version 2.53a.
9847 2002-04-22 Akim Demaille <akim@epita.fr>
9849 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
9851 2002-04-22 Akim Demaille <akim@epita.fr>
9853 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
9854 comma.
9855 Reported by Gregory Giannoni.
9857 2002-04-22 Akim Demaille <akim@epita.fr>
9859 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
9860 Fixes false failures on Darwin.

9885 Minor spelling and grammar fixes.
9887 * doc/autoconf.texi: Follow the outline suggested in the GNU
9888 Sample Texts sections of the Texinfo 4.2 manual. Most
9889 importantly, this makes sure that the copyright notices appear in
9890 all output formats. You probably need Texinfo 4.2 to generate
9891 the manual now.
9893 Fix some bugs when using "$@" when there might be zero positional
9894 arguments in cases where this matters.

9915 that is not portable to Zsh.
9917 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9919 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9920 from aclocal.m4 too.
9922 2002-04-12 Akim Demaille <akim@epita.fr>
9924 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
9926 2002-04-10 Akim Demaille <akim@epita.fr>
9928 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9929 workaround for ${1+"$@"}.
9930 * doc/autoconf.texi (Shell Substitutions): Explain it.
9931 From Oliver Kiddle and Peter Stephenson.
9933 Have M4sh perform minimal shell sanitizing.
9935 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9936 part into...
9937 (_AS_PREPARE): this new macro.
9938 (AS_PREPARE): New.
9939 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9940 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9942 Adjust Autoconf and Autotest.
9944 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9945 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9946 * lib/autotest/general.m4 (AT_INIT): Likewise.
9947 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9948 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9949 AS_SHELL_SANITIZE.
9951 Use this M4sh to generate Autoconf's shell scripts.
9953 * tests/wrapsh.as: New, precursor of wrapsh.in.
9954 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9955 on Autotest and M4sh.
9956 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9957 (wrapsh.in): New target.
9958 * bin/autoconf.as: New, precursor of autoconf.in.
9959 (autoconf.in): New target.

9966 2002-04-09 Andreas Schwab <schwab@suse.de>
9968 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9969 ac_top_builddir when setting ac_abs_top_builddir.
9971 2002-04-06 Kevin Ryde <user42@zip.com.au>
9973 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9974 (Portable Shell): Cross reference to Systemology.
9976 2002-04-05 Akim Demaille <akim@epita.fr>
9978 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9979 directories when descending in a SUBDIRS.

9982 2002-04-04 Andreas Schwab <schwab@suse.de>

9985 contains no literal separators.
9987 2002-04-03 Akim Demaille <akim@epita.fr>
9989 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)

9991 Use dnl, not the KILL diversion.
9992 Extracted from...
9993 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9994 (AC_CONFIG_LINKS): here.
9995 Adjust.
9996 Don't use the KILL diversion, as it kills spurious output, which
9997 results in failures being hidden.
9998 Use m4_defn where appropriate.
9999 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
10000 after the second argument.
10001 Use m4_defn.
10002 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
10003 syntax, as it is provided by M4sugar.
10004 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
10006 2002-04-03 Andreas Schwab <schwab@suse.de>
10008 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
10009 expanded if $# <= 2.
10011 * bin/autoreconf.in (autoreconf): Run automake after rerunning
10012 aclocal.

10019 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
10020 (_AC_COMPILER_OBJEXT): Use them.
10021 Fixes Debian #138666.
10023 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
10025 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
10027 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
10028 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
10029 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
10030 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
10031 (AC_C_CONST): Same.
10032 (AC_C_INLINE): Same.
10033 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
10034 * doc/autoconf.texi, NEWS: Document.
10035 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
10036 AC_C_CROSS.

10040 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
10041 _AS_MKDIR_P_PREPARE.
10043 2002-03-28 Kevin Ryde <user42@zip.com.au>
10045 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
10046 to avoid versions of HP C which don't allow that.
10048 2002-03-27 Paul Eggert <eggert@twinsun.com>
10050 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
10051 (AS_SHELL_SANITIZE): Invoke it.
10052 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

10058 2002-03-26 Akim Demaille <akim@epita.fr>
10060 * doc/autoconf.texi (Introduction): The GNATS base moved.
10062 2002-03-25 Paul Eggert <eggert@twinsun.com>
10064 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
10065 as POSIX requires, as it doesn't work with Zsh.
10066 * doc/autoconf.texi (Assignments): Document the problem.
10068 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10070 * doc/autoconf.texi (Limitations of Make): Mention more issue
10071 about VPATH, overriding of macros in sub-makes, and handling of
10072 SHELL.
10074 2002-03-21 Paul Eggert <eggert@twinsun.com>
10076 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
10077 problem with here-document buffer boundaries.
10079 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
10080 when reinvoking the shell, to work around problems with installers
10081 who put strange things like "cd" commands in their environments.
10083 2002-03-19 Akim Demaille <akim@epita.fr>

10091 invocations.
10092 From Nicolas Joly.
10094 2002-03-19 Akim Demaille <akim@epita.fr>
10096 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
10097 From Nishio Futoshi.
10099 2002-03-19 Akim Demaille <akim@epita.fr>
10101 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
10103 2002-03-18 Paul Eggert <eggert@twinsun.com>
10105 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
10106 (Limitations of Usual Tools): Add mkdir section.
10108 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
10109 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
10110 back on AS_DIRNAME to compute prefixes otherwise; this is
10111 roughly what mkinstalldirs does. That way, we need not have
10112 our own filename disassembler. The old disassembler did not
10113 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
10115 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
10116 Create at_test_all by a series of assignments,
10117 not by a single assignment of a long string. The latter causes ksh
10118 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
10119 presumably because of a buffer overrun.
10121 2002-03-14 Paul Eggert <eggert@twinsun.com>
10123 * lib/autotest/general.m4 (at_times_skip):
10124 Renamed from at_times. Now a boolean.
10125 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
10126 says 'times: not found'.
10128 2002-03-14 Akim Demaille <akim@epita.fr>
10130 * bin/autoreconf.in (&study_gettextize): New.
10131 (&autoreconf): Handle newest gettextize.

10133 Suggested by Andreas Schwab.
10135 2002-03-13 Akim Demaille <akim@epita.fr>

10141 * doc/autoconf.texi (Header Portability): New.
10142 Add information about stdint.h and inttypes.h from Paul Eggert.
10144 2002-03-13 Akim Demaille <akim@epita.fr>
10146 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
10147 -p'.

10150 2002-03-12 Akim Demaille <akim@epita.fr>
10152 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
10153 m4_require.
10155 2002-03-11 Andreas Schwab <schwab@suse.de>
10157 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
10158 does not do it if --with-lispdir is given.
10160 2002-03-08 Akim Demaille <akim@epita.fr>
10162 Version 2.53.
10164 2002-03-08 Akim Demaille <akim@epita.fr>
10166 * doc/autoconf.texi (Subdirectories): Clarify that the
10167 subdirectory should exist.
10169 2002-03-08 Akim Demaille <akim@epita.fr>
10171 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
10173 2002-03-08 Akim Demaille <akim@epita.fr>
10175 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
10176 aliases the actual variables, and modifications of the former
10177 affect the latter.
10179 2002-03-08 Akim Demaille <akim@epita.fr>
10181 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
10182 because of C-c: have m4 output in tmp files, then mv them.

10205 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
10206 * lib/autoconf/general.m4 (AC_INIT): More informative error
10207 message for LIBOBJ.
10209 2002-03-04 Akim Demaille <akim@epita.fr>
10211 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
10212 parallel builds.
10214 2002-03-04 Akim Demaille <akim@epita.fr>
10216 * doc/autoconf.texi (Transforming Names): Equality between target
10217 and host is irrelevant.
10218 (Specifying Names, Canonicalizing): Remove all references to the
10219 backward compatibility hooks. Rather, collect them all into...
10220 (Hosts and Cross-Compilation): this new section.
10221 * doc/install.texi (System Type): Ditto.
10222 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
10223 that `--host' implies cross-compilation.
10225 2002-03-04 Akim Demaille <akim@epita.fr>
10227 * doc/autoconf.texi (Evaluation Macros): New.
10228 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10229 useless.
10230 (_m4_foreach): Define the variant with immediate evaluation so
10231 that it contains exactly the items, not an expression which
10232 evaluation is the current item.
10233 (m4_re_string, m4_re_word): Don't over quote them.
10235 2002-03-04 Akim Demaille <akim@epita.fr>
10237 Instead of having stacking `shift's evaluated at the end, let
10238 `foreach' loops immediately evaluate them.
10240 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10241 $*. This is the n-th time I change my mind, but hopefully this is
10242 the last...
10243 (m4_lquote): New.
10244 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10245 efficient.
10246 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10247 it was only a hack for m4_text_wrap.
10248 (m4_car2): Remove, replaced by...
10249 (m4_cdr): New.
10250 (_m4_foreach): Adjust.
10251 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10252 m4_bpatsubst for clarification.
10254 2002-03-04 Akim Demaille <akim@epita.fr>
10256 * doc/autoconf.texi (Changequote is Evil): New.
10258 2002-03-03 Kevin Ryde <user42@zip.com.au>
10260 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
10261 on old systems like SunOS.
10263 2002-03-01 Peter Eisentraut <peter_e@gmx.net>

10283 From Akinori Musha.
10285 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
10287 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
10288 translate \r\n to \n.
10290 2002-02-07 Akim Demaille <akim@epita.fr>
10292 Version 2.52h.
10294 2002-02-07 Akim Demaille <akim@epita.fr>
10296 Fix Autoconf PR/209.
10297 Also reported by Frank Denis.

10301 2002-02-07 Akim Demaille <akim@epita.fr>
10303 Fix Autoconf PR/207:
10304 AC_PREFIX_PROGRAM fails with dashed program names
10306 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
10307 variable when looking for the prefix program.
10308 Now it also works for shell variables.
10310 2002-02-07 Akim Demaille <akim@epita.fr>
10312 * doc/autoconf.texi (Limitations of Builtins): More about
10313 case/esac.

10317 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
10318 case/esac, some shells don't support it.
10319 Reported by Zack Weinberg.

10322 2002-02-06 Akim Demaille <akim@epita.fr>
10324 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
10325 sure not to introduce newlines in at_groups.
10326 * lib/autotest/Makefile.am (autotest.m4f): Typo.
10328 2002-02-06 Akim Demaille <akim@epita.fr>
10330 * tests/torture.at (Configuring subdirectories): Skip if aclocal
10331 is not available.
10333 2002-02-05 Paul Eggert <eggert@twinsun.com>
10335 * doc/autoconf.texi (Specific Compiler Characteristics):
10336 Describe HP-UX cc bug workaround more accurately.
10337 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
10338 not unsigned long.
10339 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
10340 cross-compilers, too. This undoes some of the most recent change
10341 to this file.
10343 2002-02-05 Akim Demaille <akim@epita.fr>
10345 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
10346 to make sure they are up to date when `check' is run.
10348 2002-02-05 Akim Demaille <akim@epita.fr>
10350 * doc/autoconf.texi (Making testsuite Scripts): Document

10355 * lib/freeze.mk: New.
10357 2002-02-05 Akim Demaille <akim@epita.fr>
10359 Implement `autom4te --freeze'.
10361 * bin/autom4te.in (&freeze): New.
10362 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
10363 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
10365 2002-02-05 Akim Demaille <akim@epita.fr>
10367 * bin/autom4te.in (&parse_args): Implement `frozen files are
10368 optional are the sum of the previous files on the command line'.
10369 Also, pass `--reload-state=' on them, so...
10370 (handle_m4): don't.
10371 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10372 (M4sh): Rely on M4sugar.
10373 (Autotest, M4sh, M4sugar): Use frozen files.
10375 2002-01-31 Akim Demaille <akim@epita.fr>
10377 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
10378 * doc/autoconf.texi (Initializing configure): Adjust.
10380 2002-01-30 Akim Demaille <akim@epita.fr>
10382 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
10383 alphanumeric to `-' instead of `_'.
10385 2002-01-30 Akim Demaille <akim@epita.fr>
10387 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10388 for plain code, the other for cross-compilation code. The latter
10389 is now run with GCC only.
10390 * doc/autoconf.texi (Compilers and Preprocessors): New.
10392 2002-01-30 Akim Demaille <akim@epita.fr>
10394 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
10395 values.
10396 * doc/autoconf.texi (Initializing configure): Explain how to
10397 change AC_INIT default values.
10399 2002-01-29 Akim Demaille <akim@epita.fr>
10401 * tests/torture.at (Configuring subdirectories): Use configure.in,
10402 so that aclocal 1.4 works.
10403 Reported by Alexandre Duret-Lutz and Larry Schmitt.
10405 2002-01-28 Akim Demaille <akim@epita.fr>
10407 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10408 needs an argument.
10410 2002-01-28 Akim Demaille <akim@epita.fr>
10412 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10413 AUTOTEST_PATH *after* it was set.
10414 Don't put `.' in the PATH: the user should be precise and `./' if
10415 needed. In addition, given that the test suite does some `cd', if
10416 `.' is in the path, the `tested programs' sections will report
10417 programs found in the test suite's directory, while during the
10418 tests (performed in their own directory), these programs are no
10419 longer visible. In other words, the results is confusing and
10420 useless.
10421 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10423 2002-01-24 Akim Demaille <akim@epita.fr>
10425 Version 2.52g.
10427 2002-01-24 Akim Demaille <akim@epita.fr>
10429 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
10430 * doc/autoconf.texi: Finally add Akim as an author.
10432 2002-01-24 Akim Demaille <akim@epita.fr>
10434 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
10435 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
10436 Bourne. Use /bin/sh.
10437 From Andreas Buening.
10439 2002-01-24 Akim Demaille <akim@epita.fr>
10441 * config/config.guess, config/config.sub, config/texinfo.tex:
10442 Update from masters.
10444 2002-01-24 Akim Demaille <akim@epita.fr>

10449 * config/missing.m4, config/sanity.m4, config/select.m4,
10450 * config/strip.m4: Remove, to ease sync'ing with any version of
10451 Automake.
10453 2002-01-24 Akim Demaille <akim@epita.fr>
10455 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
10456 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
10457 Reported by Geir Ove Myhr.
10459 2002-01-21 Akim Demaille <akim@epita.fr>
10461 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
10463 2002-01-21 Akim Demaille <akim@epita.fr>
10465 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10466 message on invalid options.
10467 * bin/autom4te.in (parse_args): Don't use
10468 Autoconf::General::getopt with non valid options.
10470 2002-01-17 Jim Meyering <meyering@lucent.com>
10472 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10473 $ac_cv_exeext so we don't use an old, invalid, cached value.
10475 2002-01-11 Akim Demaille <akim@epita.fr>
10477 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
10478 Meyering.

10480 limitation.
10481 (Particular Functions): Document AC_FUNC_STRNLEN.

10484 2002-01-06 Akim Demaille <akim@epita.fr>
10486 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10487 package.m4, since is really depends upon configure.ac, not
10488 configure.
10489 * doc/autoconf.texi (testsuite Scripts): Adjust.
10490 * tests/Makefile.am (package.m4): New.
10491 EXTRA_DIST it since its a source.
10493 2002-01-06 Akim Demaille <akim@epita.fr>
10495 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10496 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10497 and PACKAGE_BUGREPORT from here...
10498 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10499 arguments.
10500 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10501 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10502 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
10503 * tests/tools.at (autoheader): Adjust.
10504 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
10506 2002-01-06 Akim Demaille <akim@epita.fr>
10508 * bin/autoscan.in (scan_file): Use `&used'.
10510 2002-01-03 Akim Demaille <akim@epita.fr>
10512 * doc/autoconf.texi (Output): Improved wording regarding use of
10513 AC_OUTPUT.
10514 From Olly Betts.
10516 2001-12-18 Kevin Ryde <user42@zip.com.au>
10518 * doc/autoconf.texi (Function Portability): Add notes on sscanf
10519 sometimes needing writable input.
10521 2001-12-17 Jim Meyering <meyering@lucent.com>
10523 * doc/autoconf.texi (New Macros): Tweak wording.
10525 2001-12-14 Akim Demaille <akim@epita.fr>
10527 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10528 trailing files, don't apply `-rf' to files which might not be
10529 created by configure (core, core.*, and *.core), but just `rm -f'.
10530 Suggested by Jonathan Kamens.
10532 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10534 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
10536 2001-12-14 Akim Demaille <akim@epita.fr>
10538 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
10540 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
10542 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
10543 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
10544 abs_srcdir, top_srcpath to abs_top_srcdir.
10545 (_AC_OUTPUT_FILES): Adjust.
10546 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
10547 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
10548 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10550 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
10552 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
10553 C/Fortran linking on HP/UX, by extracting the Fortran library
10554 search path from the LPATH line in the $F77 -v output.
10556 2001-12-12 Kevin Ryde <user42@zip.com.au>
10558 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10559 forbidden file descriptors table.
10561 2001-11-26 Akim Demaille <akim@epita.fr>
10563 * bin/autoscan.in (%c_keywords): Build it at top level.
10564 Map to 1 in order to simplify its uses.
10566 2001-11-26 Akim Demaille <akim@epita.fr>
10568 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10569 Remove $filepath, useless.
10570 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10571 variables, they are really part of the tokens.
10572 Split the input line on spaces and then look for tokens.
10573 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10574 because of `lex$U.$(OBJEXT)'.
10575 (&scan_files): Use "@list" instead of join.
10576 * doc/Makefile.am (CLEANFILES): Add *.fns.
10578 2001-11-26 Akim Demaille <akim@epita.fr>
10580 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10581 Remove, replaced by...
10582 * tests/wrappl.in: Be common for all the Perl executables.
10583 In particular autoscan and autoheader want -I.
10584 * configure.ac: Adjust.
10585 * lib/autoscan/headers: errno.h is portable.
10587 2001-11-26 Akim Demaille <akim@epita.fr>
10589 * bin/autoscan.in (used): New.
10590 Use it.
10592 2001-11-26 Akim Demaille <akim@epita.fr>
10594 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10595 directives.
10596 (&scan_sh_file): Remove a duplicate pattern.
10597 (&check_configure_ac): Use long options.
10598 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10600 2001-11-26 Akim Demaille <akim@epita.fr>
10602 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10603 Before, having a line containing the opening of a multi line
10604 comment made the whole line be ignored.
10606 2001-11-26 Akim Demaille <akim@epita.fr>
10608 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10609 (testsuite Scripts): Be one of its subsection.
10610 (Autotest Logs): New.
10612 2001-11-26 Akim Demaille <akim@epita.fr>
10614 Test groups are now run two directories deeper.
10616 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10617 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10618 at_top_builddir.
10619 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10620 top_srcdir, builddir and top_builddir.
10621 Use `at_*dir' relatively to the directory containing the
10622 suite, use `*dir' when relatively to the current group dir.
10624 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10626 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10627 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10628 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10629 spelling errors.
10631 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10633 * doc/autoconf.texi (Using System Type): Add an example of `case
10634 $host' usage so people quit using `case $target' everywhere.
10636 2001-11-22 Akim Demaille <akim@epita.fr>
10638 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10639 spotted by Jim Meyering.
10641 2001-11-16 Paul Eggert <eggert@twinsun.com>
10643 This patch implements a `long double' suggestion by Oliver Kiddle.
10645 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10646 static, to catch errors if the value isn't known at compile-time
10647 and the compiler supports dynamic arrays. Change its name from
10648 `_array_' to `test_array' to avoid potential name clashes.
10649 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10650 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10651 better than double. Catch a bug in GCC 2.95.2 x86.
10652 * doc/autoconf.texi (C Compiler): Document the above.
10653 * NEWS: Likewise.
10655 2001-11-13 Akim Demaille <akim@epita.fr>
10657 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10658 hand.
10659 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10661 2001-11-13 Akim Demaille <akim@epita.fr>
10663 * lib/autotest/general.m4 (AT_INIT): After having run the test
10664 group, go back to the initial directory, not to at_suite_dir.
10666 2001-11-13 Akim Demaille <akim@epita.fr>
10668 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10669 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10670 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10671 option.
10672 (AT_CHECK_CONFIGURE): Use absolute paths.
10673 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10674 The problem is still the old one: there is no means in M4 (that I
10675 know about) to create a defining macro, because there is no means
10676 to create `$1' etc., therefore, the defining macro ``swallows''
10677 all the arguments meant to the defined macro.
10679 2001-11-13 Akim Demaille <akim@epita.fr>
10681 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10682 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10683 configure.ac.
10684 * tests/aclocal.m4: Remove, as it is no longer used.
10686 2001-11-13 Akim Demaille <akim@epita.fr>
10688 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10689 variable names when referring to a single test group, or to
10690 `suite' when referring to the whole test suite.
10691 `at_last_test' is removed: m4 compute at_format itself.
10692 (at_stdout, at_stder1, at_stderr): New variables.
10693 (AT_CHECK): Use them.
10695 2001-11-13 Akim Demaille <akim@epita.fr>
10697 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10698 in PATH.
10699 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10700 Do it as soon as a test fails, don't wait till the end of the test
10701 suite.
10702 Don't remove $as_me.[0-9]*, since these files no longer exist.
10704 2001-11-13 Akim Demaille <akim@epita.fr>
10706 * tests/tools.at: Use absolute paths, since we are no longer run
10707 in place.
10709 2001-11-13 Akim Demaille <akim@epita.fr>
10711 Now that tests are running in their own private dir, there is no
10712 need to list the files to remove at the end of tests groups.
10714 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10715 (AT_data_files, at_data_files): Remove.
10716 (AT_CLEANUP, AT_DATA): Simplify.
10717 (AT_INIT): Adjust.
10718 Remove the group dir if !debug && !failed.
10719 * tests/atspecific.m4: Adjust.
10721 2001-11-13 Akim Demaille <akim@epita.fr>
10723 Start a new layout for Autotest: `testsuite' creates
10724 `testsuite.dir' in which the at-check-line etc. files are to be
10725 found, and `testsuite.dir/003' where the test group 3 is run.
10727 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10728 at_check_line_file, at_format, at_test_normalized, at_group_dir
10729 are new variables.
10730 Create the directories.
10731 Use absolute paths for at- files.
10732 (AT_CHECK): Adjust.
10734 2001-11-11 Michael Matz <matz@kde.org>
10736 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10737 (m4_car2): New.
10738 (m4_car): Properly quote arguments.
10740 2001-11-13 Akim Demaille <akim@epita.fr>
10742 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10743 with stricter rules on LIBOBJS.
10745 2001-11-12 Paul Eggert <eggert@twinsun.com>
10747 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10748 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10749 __PROTOTYPES too.
10751 2001-11-12 Akim Demaille <akim@epita.fr>
10753 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10755 2001-11-12 Akim Demaille <akim@epita.fr>

10760 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10761 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10762 specify to what the macro should be defined (typically to 1).
10764 2001-11-12 Akim Demaille <akim@epita.fr>
10766 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10767 From Jim Meyering.
10769 2001-11-12 Akim Demaille <akim@epita.fr>
10771 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10772 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10773 definition used by Automake where LEX is +/- "${missing} lex" and
10774 `missing' itself contains variables.
10776 2001-11-12 Akim Demaille <akim@epita.fr>
10778 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10779 Now that M4sh pushes BODY, the comments were output at the end of
10780 the test suites.
10782 2001-11-08 Akim Demaille <akim@epita.fr>
10784 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10785 that we can trace macros from aclocal.m4.
10786 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10787 obsoleted, and redirect to the former anyway.
10788 Reported by Ralf Corsepius.
10790 2001-11-08 Akim Demaille <akim@epita.fr>
10792 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10793 processed only if present.
10794 * tests/torture.at (Configuring subdirectories): Use autoreconf
10795 instead of successive calls to autoconf.
10796 Add a nonexistent subdirectory to exercise the patch above.
10797 Reported by Ralf Corsepius.
10799 2001-11-08 Kevin Ryde <user42@zip.com.au>
10801 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10802 doesn't accept .S files.

10808 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10809 * bin/autom4te.in (warn_forbidden): New.
10810 (handle_output): Use it.
10811 Read m4_pattern_forbid with messages.
10813 2001-11-05 Akim Demaille <akim@epita.fr>
10815 * bin/autom4te.in (--normalize): Remove.
10816 * lib/autom4te.in: Adjust.
10818 2001-11-05 Akim Demaille <akim@epita.fr>
10820 * tests/Makefile.am (testsuite): Rename this target as...
10821 ($(TESTSUITE)): this.
10822 From Nicolas Joly.
10824 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10826 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10827 the --prefix option, also remove it's argument.
10829 2001-11-05 Akim Demaille <akim@epita.fr>
10831 * doc/autoconf.texi (testsuite Invocation): Update.
10832 (Writing testsuite.at): Update.
10834 2001-11-03 Akim Demaille <akim@epita.fr>
10836 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10838 2001-11-03 Akim Demaille <akim@epita.fr>
10840 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10841 (&file_name_is_absolute): New, wrappers around routines from
10842 File::Spec.
10843 Use and export them.
10844 (&find_configure_ac): Optionally take a directory where to look at.
10845 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10846 the arguments.
10847 Default @ARGV to `.', not find_configure_ac.
10848 (&autoreconf): Argument is a directory.
10849 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10850 * doc/autoconf.texi (autoreconf Invocation): Update.
10852 2001-11-03 Akim Demaille <akim@epita.fr>
10854 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10855 (@export_forward_subs): New.
10856 Add basename, dirname, and fileparse.
10857 (@EXPORT): Adjust.
10858 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10859 Don't look for aclocal flags if we already know aclocal is not
10860 used.
10861 Move aclocal.m4t only if it exists.
10862 Reported by Ezra Peisach.
10864 2001-11-03 Akim Demaille <akim@epita.fr>
10866 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10867 passed on command line, defaulting to ./configure.ac if present.
10868 (&maybe_autoreconf, File::Find): Remove, unused.
10869 (&autoreconf): If autoconf is not used, don't try to trace.
10871 2001-11-02 Akim Demaille <akim@epita.fr>
10873 * configure.ac: Bump to 2.52g.
10875 2001-11-02 Akim Demaille <akim@epita.fr>
10877 Version 2.52f.
10879 2001-11-02 Akim Demaille <akim@epita.fr>
10881 * config/config.guess, config/config.sub, doc/standards.texi:
10882 * config/lispdir.m4: Update from masters.
10883 * configure.ac: Bump to 2.52f.
10885 2001-11-02 Akim Demaille <akim@epita.fr>
10887 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10888 Don't run aclocal when aclocal.m4 is not from aclocal.
10889 From Ezra Peisach.
10890 Don't run libtoolize and gettextize if --install is not given.
10892 2001-11-01 Paul Eggert <eggert@twinsun.com>
10894 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10895 be invoked before _AS_LINENO_PREPARE.
10896 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10897 than character ranges.
10899 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10900 invoking AS_BASENAME. Set the locale variables to 'C' if
10901 possible, as POSIX requires this to get the traditional
10902 behavior.
10903 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10905 2001-10-31 Paul Eggert <eggert@twinsun.com>
10907 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10908 with {}, as that triggers a bug in Bash 2.05.
10910 (_AS_LINENO_PREPARE): Use Sed rather than
10911 Awk. Fix the sed prepass to work even if there are multiple
10912 instances of $LINENO on the same line. Do not substitute for
10913 other variables like $LINENOT. Do not check file dates; such a
10914 check is unreliable on sufficiently fast machines, and removing
10915 the check makes the code simpler and more reliable. Check for
10916 output and chmod failures.
10918 * doc/autoconf.texi (Special Shell Variables): Document
10919 the above.
10921 2001-10-31 Akim Demaille <akim@epita.fr>
10923 * tests/Makefile.am (atconfig): Remove this target, Automake
10924 handles it now.
10926 2001-10-31 Akim Demaille <akim@epita.fr>
10928 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10929 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10930 provided, while it is optional.
10931 * configure.ac: Adjust.
10933 2001-10-26 Paul Eggert <eggert@twinsun.com>
10935 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10936 lib/Autom4te/Struct.pm:
10937 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10938 with 5.005_02.
10940 * doc/autoconf.texi (Special Shell Variables): Document some
10941 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10943 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10944 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10945 eval $LINENO is not portable in practice.
10947 2001-10-24 Akim Demaille <akim@epita.fr>
10949 * lib/Autom4te/General.pm (backname): New.
10951 2001-10-24 Akim Demaille <akim@epita.fr>
10953 * m4/: Remove, merged into...
10954 * config/: here.
10956 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10958 * doc/autoconf.texi (Shellology): Mention the problems with bash
10959 2.05's use of ANSI quoting in its `set' builtin.
10961 2001-10-22 Paul Eggert <eggert@twinsun.com>
10963 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10964 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10965 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10966 POSIX decided to standardize on the int flavor of strerror_r.
10967 Always do char* test, as there's no reason not to.
10968 Assign to a char* var, to catch strerror_r that returns int*.
10970 * doc/autoconf.texi (Particular Functions):
10971 Document the above changes. Also, document the fact that
10972 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10974 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10976 2001-10-20 Akim Demaille <akim@epita.fr>
10978 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10979 the executable was missing from the log.

10983 * lib/Autom4te/General.pm (&update_file): If destination is
10984 unchanged, remove the source.
10985 (&up_to_date_p): Don't be verbose, be debug.
10986 * bin/autoreconf.in: No longer support --m4dir.
10987 (&autoreconf): Display the full path of the configure.ac we are
10988 studying.
10989 Trace it only once.
10990 Be sure to honor --force with gettextize.
10991 Always run aclocal.
10992 * doc/autoconf.texi: Adjust.
10994 2001-10-20 Akim Demaille <akim@epita.fr>
10996 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10997 Remove, dead.
10998 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10999 `intl' is already present, as it refuses unless --force.
11000 (&parse_args): Use -I, --include instead of the old Autoconf
11001 options.
11002 ($localdir, $autoconf_dir): Remove.
11003 (@include): New.
11004 (&maybe_autoreconf): New, to preserve $_ for File::Find.
11006 2001-10-19 Jens Petersen <petersen@redhat.com>

11013 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
11014 file in @configure_input@.
11015 Don't mention `automatically' in addition to `generated'.
11016 * tests/torture.at (#define header templates): Adjust.
11018 2001-10-19 Akim Demaille <akim@epita.fr>
11020 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
11021 comment, explain how to install automatic mode selection.
11022 From Russ Allbery.
11024 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
11026 * bin/autoreconf.in (autoreconf): Display the path to the
11027 configure.ac being studied.
11029 2001-10-18 Paul Eggert <eggert@twinsun.com>
11031 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
11032 long, to work around a bug in the HP C compiler version HP92453-01
11033 B.11.11.23709.GP.
11035 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
11036 (AS_BASENAME_EXPR): New macro.
11037 (AS_BASENAME_SED): Do not assume GNU sed semantics.
11038 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
11039 and fall back on 'sed' only if the other two fail. This makes
11040 AS_BASENAME act more like AS_DIRNAME.
11041 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
11042 contains white space.
11043 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
11044 Use AS_DIRNAME, since I think it's now DOS-friendly.
11045 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
11046 Allow "dirname //FOO" to return either / or //, as POSIX allows
11047 either behavior.
11049 2001-10-10 Akim Demaille <akim@epita.fr>
11051 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
11052 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
11053 From Eric Sharkey.

11057 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
11058 m4_define, since...

11078 (&parse_args): Pass verbosity/debugging options to subtools when
11079 --debug, not when --verbose.
11080 * lib/autom4te.in (Autoreconf-preselections): New.
11081 (Autoconf): Use it.
11083 2001-10-08 Akim Demaille <akim@epita.fr>

11150 M4sugar peer, i.e., drop the `AC_PROVIDE_$1' broken marker.
11152 2001-10-08 Akim Demaille <akim@epita.fr>
11154 Use `add-log-current-defun-function' for ChangeLog creation.
11155 Suggested by Tom Tromey.
11157 * lib/emacs/autotest-mode.el (autotest-mode-map): New.
11158 (autotest-mode): Adjust.
11159 * lib/emacs/autoconf-mode.el (autoconf-mode-map): Modernize, map

11175 * tests/base.at: Adjust the tests to use AS_INIT.
11176 * tests/tools.at (AT_DATA_FORBIDDEN): New.

11188 then set CONFIG_SHELL to that shell and then re-execute
11189 ourselves with CONFIG_SHELL.
11191 2001-10-05 Paul Eggert <eggert@twinsun.com>
11193 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
11194 doesn't exist. Remove *.tmp, as a .tmp file is created during the
11195 build of $(TESTSUITE).
11197 2001-10-05 Akim Demaille <akim@epita.fr>
11199 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

11220 (AS_SHELL_SANITIZE): here. Use it.
11221 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
11222 From Paul Eggert.
11224 2001-10-04 Akim Demaille <akim@epita.fr>
11226 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
11227 combination of Awk and sed to replace $LINENO.
11229 2001-10-02 Paul Eggert <eggert@twinsun.com>
11231 * doc/autoconf.texi (Limitations of Builtins): You can't use
11232 "source"; it's not portable. Remove confusing and
11233 somewhat-incorrect example involving "." and "/".
11235 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
11236 compatibility with POSIX shells.
11238 2001-10-02 Akim Demaille <akim@epita.fr>

11241 instead of exec'ing to preserve $0 and $@.
11243 2001-10-01 Akim Demaille <akim@epita.fr>
11245 * tests/testsuite (AT_INIT) <at_pass_list>: New.

11264 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
11265 Don't use nested parenthesization. This patch was originally
11266 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
11267 but somehow it didn't get incorporated then.
11268 * doc/autoconf.texi (Limitations of Usual Tools):
11269 Clarify remark about sed and nested parenthesization.
11271 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
11272 Report an error if the size cannot be determined even though
11273 the type exists.
11274 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11275 Check for `expr' arithmetic overflow, and for compilation failure,
11276 and invoke a new argument $4 if either is discovered.
11277 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
11278 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
11280 2001-09-28 Akim Demaille <akim@epita.fr>

11299 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
11300 status when executing the ACTION-IF-FALSE.
11301 * tests/base.at (AC_TRY_*): Rename as...

11308 * tests/c.at (Extensions, C keywords)
11309 (Broken/missing compilers, AC_PROG_CPP with warnings)
11310 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
11311 (AC_PROG_CPP requires AC_PROG_CC): here and...
11312 * tests/fortran.at (GNU Fortran 77): there.
11313 * doc/autoconf.texi (autoconf Invocation): Fix the example:
11314 AC_TRY_RUN is about compilation, not shell commands.
11315 (Test Programs): AC_TRY_RUN works as used to be advertised.
11317 2001-09-27 Akim Demaille <akim@epita.fr>
11319 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
11320 Raja R Harinath:
11321 Be sure to detect when $LINENO always returns the same value.
11322 Look for the original script, basename($0) is certainly not
11323 enough.
11324 Pass the CLI arguments to `$as_me.lineno'.
11326 2001-09-25 Akim Demaille <akim@epita.fr>

11336 of --language now.
11338 2001-09-23 Akim Demaille <akim@epita.fr>
11340 * doc/autoconf.texi (Top): Wrap in @ifnottex.
11342 2001-09-23 Akim Demaille <akim@epita.fr>
11344 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
11345 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
11346 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
11347 builddir, buildpath, top_builddir, and top_buildpath.
11348 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
11349 the current directory.
11350 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
11351 variables *before* changing the current directory.

11362 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
11363 Remove.

11366 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
11367 * configure.ac: Build the position independent wrappers.
11369 * man/Makefile.am: Now that test wrappers are position
11370 independent, use them and drop dark envvar magic.
11372 2001-09-23 Akim Demaille <akim@epita.fr>
11374 * doc/autoconf.texi (Common Shell Constructs): Rename as...
11375 (Programming in M4sh): this.

11403 (Autoconf): Adjust.
11405 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>

11418 * lib/autoconf/autotest.m4: Create `package.m4'.
11419 * tests/Makefile.am (package.m4): Remove.
11421 2001-09-22 Akim Demaille <akim@epita.fr>
11423 Rely on `$LINENO' when possible instead of `__oline__'.
11425 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
11426 `$LINENO' support replacement when not supported.
11427 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
11428 them explicitly to be sure they are not output before this section
11429 (via m4_require). Cosmetic only.
11430 * lib/autoconf/c.m4, lib/autoconf/general.m4,
11431 * lib/autoconf/programs.m4: Replace all the occurrences of
11432 `__oline__' with `$LINENO'.
11433 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
11435 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
11437 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
11438 character (u: -> ue) in a code comment.
11439 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
11440 it works.
11442 2001-09-21 Akim Demaille <akim@epita.fr>
11444 * Makefile.maint (AUTOM4TE): Neutralize autom4te.

11459 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11461 * doc/autoconf.texi (File System Conventions): Clarify the use of
11462 PATH_SEPARATOR.
11463 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
11464 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
11465 be used instead of ':'.
11466 * lib/autotest/general.m4: Replace occurrences of ':' in
11467 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
11469 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11471 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
11472 arguments. Fixed a typo.
11474 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11476 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
11477 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
11479 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11481 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
11482 * bin/autoupdate.in: Ditto.
11483 * bin/autoheader.in: Reworded a few comments.
11484 * bin/autoconf.in: Reworded help text for a few options.
11485 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
11486 * bin/autoscan.in, bin/autoupdate.in: Ditto.
11488 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11490 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
11491 already have $file). Set output files to binary mode (helps avoid
11492 CR issues on DOSish systems).
11494 2001-09-19 Akim Demaille <akim@epita.fr>
11496 * lib/autotest/general.m4: Englishoes.
11497 From Tim Van Holder and Alexey Mahotkin.
11499 2001-09-18 Paul Eggert <eggert@twinsun.com>
11501 * doc/autoconf.texi (Common Shell Constructs): New node,
11502 documenting AS_DIRNAME.
11503 (Limitations of Usual Tools): Refer to it when discussing dirname.
11504 Also, update discussion of POSIX standard to reflect latest draft.
11506 * lib/autoconf/c.m4:
11507 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11509 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11510 Do not pass a first argument with leading '-'
11511 to expr, by parenthesizing initial integers that might be negative.
11513 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11514 now merely checks whether it is an error to pass an argument
11515 to getpgrp.
11517 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11518 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11519 whether it is a (compile-time) error to pass an argument to
11520 getpgrp. This simpler test supports the revised documentation,
11521 and is all that AC_FUNC_GETPGRP's users really need.
11523 2001-09-18 Akim Demaille <akim@epita.fr>
11525 * doc/autoconf.texi (Limitations of Make) <$<>: New.
11527 2001-09-18 Akim Demaille <akim@epita.fr>

11531 * lib/autotest/general.m4 (AT_INIT): Adjust.
11533 2001-09-18 Paul Wagland <paul@wagland.net>
11535 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11536 correctly.
11537 Add test for AS_BASENAME.
11538 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11539 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11540 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11541 * tests/base.at: Fixed the expected responses. The old ones were
11542 one line out...
11543 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11544 the documentation claims it should (and how it behaved in 2.13).
11546 2001-09-18 Akim Demaille <akim@epita.fr>
11548 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11549 the AC_CONFIG_COMMANDS invocation.
11550 This also solves the name clash problems.
11551 Don't set the package's ID.
11552 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11553 No longer to be shipped.
11554 (version.in): Remove.
11555 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11556 * lib/autoconf/status.m4: Adjust.
11557 Use `m4_PACKAGE_STRING'.
11558 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11559 the only optional argument is the name of the test suite.
11560 Expect `package.m4' to define the package signature.
11561 * lib/autom4te.in (Autotest): Add `package.m4?'.
11562 * tests/Makefile.am (package.m4): New.
11563 * tests/suite.at: ifnames is a victim.
11565 2001-09-18 Akim Demaille <akim@epita.fr>
11567 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11568 AC_LIBSOURCE, AC_CONFIG_FILES.
11569 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11570 program version string doesn't match the package's.
11571 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11572 after `(cached)'.
11574 2001-09-17 Paul Eggert <eggert@twinsun.com>
11576 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11577 Allow expression to return any value that can fit into unsigned long
11578 (not int, as before). Check for output errors.
11580 2001-09-17 Bruno Haible <haible@ilog.fr>
11582 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11583 Always include <stdio.h> and <stdlib.h>. Evaluate
11584 the expression in an extra function before these includes. Call
11585 fprintf "%d" only after ensuring the argument is of type 'int'.
11586 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11588 2001-09-17 Paul Eggert <eggert@twinsun.com>
11590 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11591 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11592 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11593 when they don't exist.
11595 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11596 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11597 need it.
11599 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11600 version with the version used by fileutils 4.1, except use
11601 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11602 we don't need it.
11604 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11606 2001-09-13 Akim Demaille <akim@epita.fr>

11609 _first_.

11646 * lib/autotest/general.m4 (AT_INIT): Create and remove
11647 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

11758 2001-09-05 Akim Demaille <akim@epita.fr>
11760 Be ready to handle filenames as stupid as `dnl.at', for if even
11761 the maintainer is dumb enough to do that...
11763 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11764 excellence in M4 quotation: consider `__file__' is active.
11766 And BTW, when invoking m4, pass the --include in the right order:
11767 the wrong one.
11769 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
11770 4m.

11797 New, extracted from main.
11798 Use IO::File wherever possible.
11799 (input.m4): Be constant, use -I instead of hard coding $tmp.
11800 Therefore be a quoted heredoc.
11801 Don't invoke `_au_disable', since ac was not loaded, but just
11802 `unm4.m4'.
11804 2001-08-31 Akim Demaille <akim@epita.fr>
11806 Version 2.52d.

11829 2001-08-31 Akim Demaille <akim@epita.fr>
11831 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11832 (testsuite Scripts): There is no such thing as `atconfig.in'.
11833 And actually one diagram is missing: test suite runtime.
11835 2001-08-31 Akim Demaille <akim@epita.fr>
11837 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11838 inverse order.
11840 2001-08-31 Akim Demaille <akim@epita.fr>
11842 * bin/autoupdate.in (@include): `installcheck' revealed the path
11843 to m4sugar was lacking!
11845 2001-08-31 Akim Demaille <akim@epita.fr>
11847 * man/Makefile.am (.x.1): We really have to pass
11848 autom4te_perllibdir.
11850 2001-08-31 Akim Demaille <akim@epita.fr>
11852 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11853 debug scripts, in particular passing explicitly listed tests to
11854 run is stupid.
11856 2001-08-31 Akim Demaille <akim@epita.fr>
11858 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11859 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11860 Use directly autom4te, not autoconf.

11885 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11886 (autoheader): Pass --force since the test suite goes too fast for
11887 the time stamps.
11888 Adjust to the new autoheader messages.
11890 2001-08-31 Akim Demaille <akim@epita.fr>
11892 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

11902 Drop AC_MACRODIR dead for real.
11903 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11904 `autoheader: `config.hin' is created'.
11905 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11907 2001-08-31 Akim Demaille <akim@epita.fr>
11909 * bin/autoheader.in: Rewrite in Perl.

11912 2001-08-31 Akim Demaille <akim@epita.fr>

11915 Map --localdir, --autoconf-dir onto it.
11916 Forward autom4te's options instead of interpreting them.
11917 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11918 There is no such envvar since the inception of autom4te.cfg.
11919 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11920 * bin/autoupdate.in: Adjust, and perform more control.

11927 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11928 optionally `FILE'.
11929 Use -e, not -f, since /dev/null for instance is OK.
11930 (&parse_args): Adjust.
11931 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11933 2001-08-31 Akim Demaille <akim@epita.fr>
11935 * configure.ac: Also find tested executables in bin.
11936 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11937 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11938 installed peer executables, only PATH is allowed to resolve it.
11939 Pass `autoconf_dir' via options, not via invisible envvars.
11940 * lib/Autom4te/General.pm (&find_peer): Remove.
11941 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11942 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11943 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11944 find the executables for it.
11945 * tests/Makefile.am: Major cleanup. Too lazy to document...
11946 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11947 We only need PERL.
11948 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11949 indeed related to running the test suite, while passing
11950 --autoconf-dir and others is related to running non installed
11951 Autoconf executables. So don't do that, leave it to...
11952 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11953 * tests/autoscan: New.
11954 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11955 refer to library files: rely on --language.
11957 2001-08-29 Akim Demaille <akim@epita.fr>
11959 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

11962 2001-08-29 Akim Demaille <akim@epita.fr>
11964 * doc/autoconf.texi: Strip the @nodes.
11965 Suggested by Paul Eggert.

11968 2001-08-29 Akim Demaille <akim@epita.fr>
11970 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11971 Suggested by Paul Eggert.
11973 2001-08-29 Akim Demaille <akim@epita.fr>
11975 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11976 download in a tmp dir.
11978 2001-08-29 Akim Demaille <akim@epita.fr>
11980 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

11999 * lib/autotest/general.m4: Use
12000 foo=`(command) 2>/dev/null`
12001 not
12002 foo=`command` 2>/dev/null
12003 (at-devnull): Rename as...
12004 (AT-devnull): this.
12005 (--clean): Remove AT-* files too.
12006 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.

12041 * lib/autotest/general.m4 (AT_INIT): Log the command line.
12042 Support `VAR=VAL' as arguments.

12513 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
12515 * tests/semantics.at (AC_C_BIGENDIAN): New test.
12517 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12519 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12520 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12521 * doc/autoconf.texi (C Compiler Characteristics): Update
12522 documentation for AC_C_BIGENDIAN.
12524 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12526 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12527 magic values from an object file when cross-compiling.
12528 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12530 2001-08-10 Akim Demaille <akim@epita.fr>
12532 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12533 effects.
12534 Suggested by Russ Allbery.
12536 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12538 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12539 current $prefix to the sub-configures.
12541 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12543 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12544 extension (needed on BeOS). Reported by Guido van Rossum.
12546 2001-08-09 Akim Demaille <akim@epita.fr>
12548 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12550 2001-08-07 Akim Demaille <akim@epita.fr>
12552 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12553 removed.
12554 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12555 No need to remove the files before and after the each test, before
12556 each test and at the end of the suite is enough.
12557 Display only the children `times', not the shell's.
12558 If the test failed or was skipped, at-times is not available.
12560 2001-08-07 Akim Demaille <akim@epita.fr>
12562 Always produce testsuite.log, including when there are no
12563 failures. This helps getting information on skipped tests, and
12564 duration of the tests. Err, implement the latter btw.
12566 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12567 Dump information on the first run of each test.
12568 (AT_CLEANUP): Create `at-times' containing the duration of the
12569 test group.
12571 2001-08-07 Akim Demaille <akim@epita.fr>
12573 The use of `dumpstat' revealed that `len' was used although it
12574 should not. m4_text_wrap was using it, but in the Autoconf world
12575 where it is legal. Hence (i) test M4sh in its own world, not
12576 Autoconf's, and (ii), ahem, fix the bug :)
12578 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12579 does not like `' instead of [].
12580 (AT_INIT): Forbid `^_?AT_'.
12581 And don't output such tokens.
12582 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12583 `script.as', and `autom4te.cache'.
12584 Remove `empty' and `macro' which are no longer used.
12585 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12586 * tests/m4sugar.at: Use it.
12587 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12589 2001-08-07 Akim Demaille <akim@epita.fr>
12591 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12593 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12595 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12597 2001-08-04 Akim Demaille <akim@epita.fr>
12599 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12600 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12601 AC_TRY_LINK.
12602 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12603 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12604 (AC_F77_MAIN): Likewise.
12606 2001-08-04 Akim Demaille <akim@epita.fr>
12608 Don't rely on M4sugar outputting the patterns in files, since we
12609 might process the output _without_ running m4, hence without these
12610 files.
12612 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12613 * bin/autom4te.in (@Request::includes): Remove, unused.
12614 (@Request::source): Rename as...
12615 (@Request::input): this.
12616 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12617 (&handle_output): Fetch the patterns from the traces.
12618 `$forbidden' and `$allowed' are constant: use m//o.
12619 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12620 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12622 2001-08-04 Akim Demaille <akim@epita.fr>
12624 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12625 autoconf', i.e., in addition to caching traces, cache the output.
12627 * bin/autom4te.in (Request::cache): Rename as...
12628 (Request::id): this.
12629 ($cache, $icache, $tcache, $ocache): New.
12630 (&handle_m4): Save M4 output in the cache instead of $tmp.
12631 (&handle_output): Adjust.
12632 (&up_to_date_p): Check that the output cache is up to date too.
12633 (top level): Run `&handle_m4' iff force or the cache is invalid.
12634 Run `&handle_output' if the output cache is more recent.
12636 2001-08-04 Akim Demaille <akim@epita.fr>
12638 * bin/autom4te.in ($force): New.
12639 (&parse_args, &print_usage): -f, --force is a new option.
12640 (&handle_output): CPP directives might have spaces after `#'.
12641 (&parse_args): The first file only can be frozen.
12643 2001-08-04 Akim Demaille <akim@epita.fr>
12645 Don't let autom4te compute the `include' traces several times:
12646 first check that the trace cache file is up to date, and then
12647 compare its timestamp with that of the output.
12649 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12650 the preamble. Don't require 5.005 as Autom4te::General does it,
12651 and better yet (use `use', not `require'!).
12652 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12653 Class::Struct as Autom4te::Struct.
12654 * lib/Autom4te/General.pm (File::stat): Use it.
12655 (&mtime): New, export it.
12656 * bin/autom4te.in: Use it.
12657 Declare `$req' is invalid if it is outdated.
12658 Don't declare it valid before saving it if something went wrong.
12660 2001-08-04 Akim Demaille <akim@epita.fr>
12662 Autom4te shall not encode Autoconf data, and preselecting traces
12663 must be proposed to the users.
12665 * bin/autom4te.in (@required_trace): Remove.
12666 (@preselect): New.
12667 (&parse_args, &print_usage): -p, --preselect is a new option.
12668 (&up_to_date_p): Adjust.
12669 * bin/autoconf.in: Preselect some Autoconf macros.
12671 2001-08-04 Akim Demaille <akim@epita.fr>
12673 * tests/tools.at (autoconf --trace: user macros): Check traces on
12674 macros invoked without arguments, and macros invoked with multiple
12675 lines arguments.
12677 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
12679 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
12680 arguments.
12682 2001-08-03 Akim Demaille <akim@epita.fr>
12684 * bin/autoconf.in ($@): Work around the usual sh bug.
12685 From Nicolas Joly.
12687 2001-08-03 Akim Demaille <akim@epita.fr>
12689 Clean up the handling of the M4 builtins tracing exception.
12691 * bin/autom4te.in (Request::request): Don't complete M4 builtins
12692 trace requests.
12693 (@m4_builtins): Rename as...
12694 (@m4_builtin): this.
12695 (%m4_builtin_alternate_name): New.
12696 (&parse_args): Complete the trace requests with alternate names.
12697 (&handle_traces): Hence no longer do it here.
12698 (&trace_requests): Remove, unused.
12700 2001-08-03 Akim Demaille <akim@epita.fr>
12702 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
12703 m4_if, and m4_wrap.
12705 2001-08-03 Akim Demaille <akim@epita.fr>
12707 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
12708 (m4_divert_pop): Dump the whole diversion stack when a diversion
12709 mismatch happens.
12710 * bin/autom4te.in (&handle_output): Remember of the first
12711 occurrence of a possibly undefined macro, not the last.
12712 Complain about the possibly undefined macros in the same order as
12713 the appear in the output.
12714 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
12715 * tests/tools.at (autoconf: forbidden tokens, basic)
12716 (autoconf: forbidden tokens, exceptions): No longer sort
12717 autoconf's stderr, as it is now deterministic.
12718 Check that `dnl' is caught.
12720 2001-08-01 Akim Demaille <akim@epita.fr>
12722 * configure.ac: Bump to 2.52c.

12734 2001-08-01 Akim Demaille <akim@epita.fr>

12737 `die'.
12738 (&END): New.
12739 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
12740 `END', as `Autom4te::General::END' will be triggered.
12741 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
12742 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

13174 provide an alternate 'main' function name, using the 'main' from
13175 the Fortran libraries.
13176 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
13177 cross-language link tests can be performed successfully.
13178 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
13179 after $LIBS, for consistency; this should be the general rule since

13186 at-stdout and at-stderr instead of removing the newline
13187 from the echo output, which is not guaranteed to work.

13300 Automake), include the separator themselves.
13302 * acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
