430 for C++; this drops support for anonymous struct and union types,
431 which were problematic anyway.

452 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
453 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
454 works but the latter doesn't, then it's a valid type.
455 This lets people use function types and so forth.
456 For C++ there doesn't seem to be a simple solution, so leave it alone.
457 (AC_CHECK_SIZEOF): Allow argument to be a variable.
458 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
459 AC_CHECK_TYPE; that wasn't documented or necessary.

512 nonstandard grep R.E. escape sequences.
514 2007-03-17 Jim Meyering <jim@meyering.net>
516 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
517 (Limitations of Usual Tools): Also list \< and \>, and mention that
518 HP-UX's grep, like the one from Solaris, does not support that syntax.
520 2007-03-09 Stepan Kasal <kasal@ucw.cz>
522 * doc/autoconf.texi (Specifying Names): `--host' does not
523 change the build type.
525 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
527 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
528 suggests AC_CONFIG_HEADERS.
529 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using

539 universal binaries. Problem reported by Elias Pipping.
541 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
543 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
544 * doc/autoconf.texi (C Compiler): Document this. There is a new
545 extra argument ACTION-IF-UNIVERSAL.
546 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
547 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
548 Reindent for sanity's sake.
550 2007-02-24 Eric Blake <ebb9@byu.net>

561 status of rm so we know when it failed.
562 If cleaning of test dir failed before running the test, warn.
563 Output the line separator in verbose mode before the warning
564 to make clear the warning belongs to the following test.
566 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
568 * doc/autoconf.texi (Parentheses): Mention problem with (( in

581 carriage return.
582 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
583 with traditional Awk and begin.
584 * tests/torture.at (Limitations of Builtins): Document the problem
585 with Bash 2.03 printf.

591 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
592 input from /dev/null in awk test, so even Solaris /usr/bin/awk

629 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
630 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
631 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
632 substitution will still be done by the special code.
633 Report by Jim Meyering.

646 * tests/torture.at (Substitute and define special characters):
647 Test all 8 bit non-NUL characters.
648 Report against Automake by Patrick Welche.
650 2007-01-15 Stepan Kasal <kasal@ucw.cz>
652 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
654 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
656 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
657 early on the reader side, drop stderr of the input to avoid
658 `broken pipe' error output; this may happen even with shell
659 builtin `echo' of some bash versions. Reports by Ian Macdonald
660 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
662 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
664 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
665 separate items of `ac_user_opts', to avoid long lines.
666 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
668 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
670 * doc/autoconf.texi: Fix some typos.
672 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
674 Fix some wording problems noted by Paolo Bonzini in:
675 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
676 * doc/autoconf.texi (Signed Overflow Examples): Give more
677 discussion about the allow_superuser_privileges example,
678 and change it a bit to make things clearer.
679 (Optimization and Wraparound): Clarify whether the compiler
680 will generate an infinite loop for the example derived from
681 Autoconf's mktime test.
682 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
683 Also, clarify unsigned multiplication overflow.
685 2007-01-04 Eric Blake <ebb9@byu.net>
687 * bin/Makefile.am (RELEASE_YEAR): New macro.
688 (edit): Use it to supply correct copyright year to scripts.
689 * bin/autoconf.as (version): Use it.
690 * bin/autoheader.in ($version): Likewise.
691 * bin/autom4te.in ($version): Likewise.
692 * bin/autoreconf.in ($version): Likewise.
693 * bin/autoscan.in ($version): Likewise.
694 * bin/autoupdate.in ($version): Likewise.
695 * bin/ifnames.in ($version): Likewise.
697 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
699 * doc/autoconf.texi (Integer Overflow): Revised based on today's
700 feedback. The most important changes document what happens when
701 you convert an out-of-range value to a signed integer type, and
702 say that (sum < a) != (b < 0) reliably detects overflow when sum =
703 a + b.
705 * doc/autoconf.texi (Integer Overflow): Greatly expand and
706 rewrite, taking notions from the recent discussion on the gcc and
707 autoconf mailing lists; please see
708 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
709 and follow the many links.
710 (Integer Overflow Basics, Signed Overflow Examples):
711 (Optimization and Wraparound, Signed Overflow Advice):
712 (Signed Integer Division): New sections.
714 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
716 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
717 preprocessor macro arguments in traced name.
718 * doc/autoconf.texi (Defining symbols): Document longstanding
719 support for AC_DEFINE-ing macros with arguments, and document
720 behavior when the same variable has multiple AC_DEFINEs.
721 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
722 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
723 macros directly, giving much shorter and simpler code.
725 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
727 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
728 space before "$ac_configure_args" to prevent a 'config.status
729 --recheck' failure if ac_configure_args doesn't contain a leading
730 space. This works around a problem with the XEmacs configure.ac,
731 which uses the (undocumented) ac_configure_args variable
732 inconsistently with Autoconf.
734 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
736 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
737 Include <limits.h>, and use its INT_MAX to rewrite the
738 j loop so that it does not overflow 'int'. Problem reported by
739 Ralf Wildenhues in
740 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
741 Play it safe by shifting left by 1 rather than multiplying by 2,
742 as GCC is less likely to optimize this away when the value
743 is signed (when it assumes overflow leads to undefined behavior).
744 Also, don't assume time_t uses two's complement.
746 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
748 * tests/torture.at (Substitute a 2000-byte string): Avoid using
749 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
750 dumps core on it. Report by Tim Rice.
752 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
754 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
755 --disable-option-checking to --help output even when
756 AC_PRESERVE_HELP_ORDER is not used.
757 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
758 --with argument, rather than argument with [-.] replaced by
759 underscores.
760 * NEWS: Fix typo in previous change; the news was in the
761 wrong section.
763 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
765 * NEWS: Warnings are now generated by default for unknown
766 --enable-* and --with-* options.
767 * doc/autoconf.texi (Option Checking): Renamed from
768 (Configure Option Checking). Tighten up the wording a bit.
769 (External Software, Package Options): Cross-reference to Option
770 Checking, and use this to shorten our section.
771 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
772 "$x" to test "x$foo" != x.
773 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
774 Don't warn if $enable_option_checking is "no".
775 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
776 ac_unrecognized_opts to the empty string.
777 Don't echo the unrecognized opts, as this might mishandle
778 backslashes or leading -.
779 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
780 usage next to the other --disable-FEATURE options in the
781 help string.
783 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
785 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
786 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
787 Print warning for unrecognized --with and --enable options
788 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
789 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
790 Disable option checking when subdirs are configured.
791 (AC_OUTPUT): If warnings are enabled, print warning about
792 unrecognized --with and --enable options at the end of
793 the configure output (as well as at the beginning).
794 * doc/autoconf.texi (Option Checking): New node.
795 Document new option warning functionality.
797 2006-12-16 Eric Blake <ebb9@byu.net>
799 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
800 * NEWS: Start news for current version.
802 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
804 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
805 Define HAVE_GETMNTENT to 1, not to the empty string.
806 Problem originally reported by Jochen Friedrich in
807 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
809 This change prompted by a problem report by Andrey Simonenko in
810 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
811 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
812 object-like macros only, in the traditional portable character
813 set.
814 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
815 Warn about attempts to define things that are not identifiers.
816 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
817 awful hack that AC_DEFINEd macro names containing parentheses.
819 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
821 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
822 too drastic, even if Texinfo in theory requires it for info mode.
824 (config.status Invocation): Renamed back from Recreating a
825 Configuration).
826 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
827 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
829 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
831 * NEWS: Version 2.61a.
833 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
834 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
836 * NEWS: Document changes with echo and printf, and the lack
837 of limits on the total size of multi-line values of substituted
838 variables, and the AC_FUNC_FSEEKO fix.
840 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
842 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
843 Writing configure.ac.
844 (Autoconf Input Layout): Renamed from configure.ac Layout.
845 (Recreating a Configuration): Renamed from config.status Invocation.
846 (Obsolete Recreation): Renamed from Obsolete config.status Use.
847 (acconfig Header): Renamed from acconfig.h.
848 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
849 (Writing Testsuites): Renamed from Writing testsuite.at.
850 (Autom4te Cache): Renamed from autom4te.cache.
852 * BUGS: Remove mention of VPATH problem, since it's now documented
853 not to be a bug in the Autoconf build procedure itself, but rather
854 a problem with the proprietary `make' programs.
856 * doc/autoconf.texi (Build Directories): Add a cross reference
857 to VPATH and Make.
859 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
860 * doc/standards.texi: Sync from gnulib.
862 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
863 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
864 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
865 generated automatically.
867 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
869 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
870 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
871 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
873 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
875 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
876 `CEOF$ac_eof' special marker, the awk script cannot contain a
877 line matching `^CEOF', so this is not needed any more.
878 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
879 special marker in the test.
881 2006-12-06 Stepan Kasal <kasal@ucw.cz>
883 * tests/tools.at (autom4te preselections): Use `find -newer';
884 remove one of the sleeps.
886 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
887 more readable, using ...
888 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
890 * doc/autoconf.texi (autoheader Invocation): Do not double-
891 quote the parameter of `AH_BOTTOM' in the example.
893 2006-12-05 Stepan Kasal <kasal@ucw.cz>
895 * doc/autoconf.texi (Configuration Headers): Remove the
896 example with multiple input files.
897 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
898 multiple input files.
900 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
902 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
903 creating the awk substitution script, handle one input line at a
904 time, so that the maximum length of a substituted (multi-line)
905 value is not limited by the size of the sed pattern space.
906 The trade-off is a slightly repetitive sed script.
907 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
908 can only have up to 7 characters, due to Solaris 10 /bin/sed.
909 * tests/torture.at (Substitute a 2000-byte string): Increase the
910 test with several long lines, they should not be caught by sed
911 limits any more.
913 * tests/tools.at (autom4te preselections): New test, to flag
914 entries missing from autom4te.cfg.
915 Report by David Byron <dbyron@hheld.com>.
917 * tests/torture.at (Substitute a 2000-byte string): Actually use
918 AC_PROG_AWK, so the last change works as intended.
919 (Substitute and define special characters): Likewise.
920 (Substitute a newline): Likewise.
922 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
923 instead of `awk' consistently.
924 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
925 * tests/torture.at (Torturing config.status): Test both the
926 result of AC_PROG_AWK and plain awk.
927 (Substitute a 2000-byte string): Likewise.
928 (Substitute and define special characters): Likewise.
929 (Substitute a newline): Likewise.
931 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
933 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
934 can be assigned to a function pointer. Problem reported by
935 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
936 part of a patch by Ralf Wildenhues in that same bug report.
938 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
940 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
941 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
943 2006-12-01 Eric Blake <ebb9@byu.net>
945 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
946 cross-compiling from cygwin to mingw.
947 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
948 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
949 to lib/autoconf/c.m4.
951 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
953 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
954 string for more reliable failure. Wrap the entire test that
955 causes the broken Solaris printf to dump core, in a subshell,
956 so the segmentation fault message is reliably suppressed.
957 Fix shell expansion errors by using /usr/ucb/echo always;
958 avoid an error on systems without it by another subshell.
959 Avoid m4 expansion of `$1'. Set the zeroth argument of the
960 subshell-$as_echo to `as_echo', for better error message.
962 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
964 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
965 `BASH_SOURCE' contain a newline, set them to empty, as they may
966 not be unset.
968 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
970 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
971 years and is too hard to maintain now. The last straw was
972 reported by Jerker Baeck in
973 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
974 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
975 * doc/autoconf.texi (Particular Functions): Move
976 AC_FUNC_SETVBUF_REVERSED from here...
977 (Obsolete Macros): ... to here. Say that it does nothing now.
978 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
979 Turn into (almost) a no-op.
981 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
982 (AC_C_VOLATILE):
983 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
984 These macros are obsolescent and new applications shouldn't need them.

1015 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1017 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1018 in the sed script that mangles the awk script: delete up to the
1019 first exclamation mark only.
1020 * tests/torture.at (Substitute and define special characters):
1021 Test '!' too.
1023 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1025 Rewrite config files generation: avoid quadratic growth in
1026 the number of substituted variables by using awk instead of sed
1027 for the bulk of the substitutions.
1028 * NEWS: Mention this.
1029 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
1030 forbidden in the output (and thus input) file.
1031 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
1032 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
1033 generate just one large awk script for substitutions,
1034 eliminating much of the earlier complexity, while adding some
1035 new complexity. Only expand the substitution templates at
1036 configure time, for smaller configure script size. If
1037 _AC_SUBST_FILES are used, test 'awk' for working getline support
1038 at config.status time. If absent, interpolate through the
1039 shell. The awk script was written with much help
1040 from Paolo Bonzini and Paul Eggert.

1047 substitute a line with 1000 words, and a variable with several
1048 long lines.
1049 (Substitute and define special characters): Test awk special
1050 characters, and put substitution input strings `@foo@' in the
1051 output, to test that no recursion happens; test several other
1052 combinations from Paolo Bonzini.
1054 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
1056 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
1057 that replaced echo with AS_ECHO where this wasn't necessary.
1058 Problem reportd by Ralf Wildenhues.
1059 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,

1069 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim

1071 Mention that FS must be a single character, and a few other
1072 99-byte limits of traditional Awk.
1073 Mention that if (i in a) doesn't work with traditional Awk.

1084 that lack printf, but for now let's assume all such hosts
1085 are dead (if not, we should get reports of test failures).
1087 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>

1270 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
1271 and Stepan Kasal <kasal@ucw.cz>
1273 Handle special characters in test case titles correctly.
1274 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
1275 properly.
1276 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
1277 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
1278 argument. Extend to check titles printed by ./micro-suite and
1279 ./micro-suite -l and the title in micro-suite.log.
1280 (Backquote in a test title,
1281 Single-quote in a test title,
1282 Double-quote in a test title): Don't expect failure anymore.
1283 (Backslash in a test title): Put a non-whitespace character after the
1284 backslash so that Bourne shells might actually see it as an escape
1285 sequence.
1286 (Brackets in a test title,
1287 Pound in a test title,
1288 Comma in a test title,
1289 Quoted Macro in a test title,

1296 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
1297 The visible effect was a stray [] in the testsuite output.
1299 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1301 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
1302 `trap ... 0' inside a function, for AIX sh.
1304 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1306 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1307 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1308 5363) simply issues a warning when dividing by zero at compile
1309 time. Problem reported by Elias Pipping.
1311 2006-10-26 Eric Blake <ebb9@byu.net>
1313 * THANKS: Update.
1314 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1315 show effect on macros that expand with commas.
1316 Reported by Joel E. Denny.
1318 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

1344 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1345 reported by Nelson H. F. Beebe for Coreutils 6.4.
1347 * tests/tools.at (autoconf --trace: user macros): Remove test
1348 for tracing multiline macros, since m4 1.4.7a uses a different
1349 way to number lines. Problem reported by Ralf Wildenhues.
1351 2006-10-24 Stepan Kasal <kasal@ucw.cz>
1353 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1354 /dev/null since the heuristics for interactive behaviour was
1355 fixed in CVS m4.
1357 * bin/autom4te.in: With --force, always refresh the output
1358 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

1379 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1380 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
1382 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1425 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1427 (Imported from Automake.)
1428 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1429 which incorrectly sets the mode of an existing destination
1430 directory. In some cases the unpatched install-sh could do the
1431 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1432 system. We hope this is rare in practice, but it's clearly worth
1433 fixing. Problem reported by Alex Unleashed in
1434 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1435 Also, don't bother to check for -m bugs unless we're using -m;
1436 suggested by Stepan Kasal.

1485 added to the template can get mangled.
1487 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1489 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,

1495 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

1505 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1507 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
1508 the NonStop platform.
1509 * doc/autoconf.texi (Posix Variants): Likewise.
1510 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1512 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1513 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1514 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1515 Use a better substitute, by inspecting the output of "ls"
1516 rather than just using ":".
1517 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1518 rather than AS_EXECUTABLE_P, since we needn't worry about
1519 non-regular files here.
1521 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1522 due to configuration hassles with this. See Tonya Underwood's report
1523 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1524 * doc/autoconf.texi (Special Shell Variables): Likewise.
1526 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1527 Stepan Kasal <kasal@ucw.cz>
1529 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
1530 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
1532 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1534 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1535 initialization which is not inherited through the environment
1536 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1537 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1539 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1541 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1542 problems with mkdir -p -m.
1544 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1546 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1547 comment about ac_cpp_err; it was incorrect, and anyway
1548 ac_cpp_err is being removed below.
1549 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1550 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1551 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1552 nobody uses it.
1553 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1554 with werror_flag and conftest.err and so forth. This is more
1555 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1556 and anyway the user shouldn't normally want to see this gorp logged.
1557 Problem reported by Ralf Wildenhues.
1558 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1559 empty, not 'no', since the rest of the code uses 'test -z'.
1561 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1563 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1564 Use a single call to AC_DO_TOKENS rather than multiple, for
1565 efficiency.
1566 (_AC_LINK_IFELSE): Test that resulting file is executable.
1567 Problem reported by mwoehlke in
1568 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1570 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1571 than creating a file to use with test -x; this is much faster.
1573 2006-10-02 Bruno Haible <bruno@clisp.org>
1575 * lib/autom4te.in (Automake-preselections): Add
1576 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1578 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1580 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1581 standard error, `experr' should be used, not `expout'.
1583 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1585 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1586 fseeko testing program twice; just use the earlier result.
1587 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1588 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1589 still doesn't let the program compile.
1590 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1591 failed.
1593 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1594 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1595 include it, without including anything else.
1596 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1597 expressions.
1598 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1600 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1602 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1603 `error.h', and include it, for a `error_at_line' prototype.
1604 Use a nonempty format string in the link test.
1605 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1606 for a declaration of wait3.
1608 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1610 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1611 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1612 can apply to constants too, and that it checks for macro defns.
1613 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1614 and simply cast the identifier to void. This handles structure
1615 values. Problem reported by Ralf Wildenhues.
1616 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1618 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1672 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
1673 --error-output, to avoid warnings with M4 2.0.
1675 2006-09-19 Stepan Kasal <kasal@ucw.cz>
1677 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

1688 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
1689 mistaken comment: the path has to be relative; do not use
1690 the path at runtime.
1692 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1694 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

1704 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
1705 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
1706 for the existence of the directory at configure-time. That's
1707 too late, anyway. Problem reported by Stefan Seefeld.
1709 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
1710 7.1.4 /usr/bin/posix/sh described by Tim Rice in
1711 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
1713 2006-09-11 Stepan Kasal <kasal@ucw.cz>
1715 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
1716 works with GNU M4 1.4.3 again; make the normalized form
1717 match the current m4 message; fix the description.
1718 * test/tools.at (autom4te cache): Adapt to the change.
1720 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
1722 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
1723 to catch glibc bug 2821
1724 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
1726 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1727 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1728 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
1729 assume C89.

1751 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1752 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1753 accept files with extension `.f'. For consistency, also prefer
1754 xlf over f77.
1755 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
1756 from last patch.

1777 except the first two arguments are reversed.
1778 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1779 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
1780 caches nor outputs a diagnostic. Suggested by Bruno Haible.

1788 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
1790 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
1791 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
1792 programs should use their Gnulib counterparts.
1793 * doc/autoconf.texi (Particular Functions): Likewise.

1795 obsolete macros with uses of non-obsolete macros.

1823 Fix Lex library problem reported to us by Julio Garvia.
1824 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
1825 for the default, which the user can override.
1826 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1827 deal with LEXLIB.
1828 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1829 didn't work if some values were cached but not others. Test for
1830 broken lex libraries like native ia64-hp-hpux11.22; see
1831 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1832 work around the problem by preferring an empty LEXLIB to -lfl or
1833 -ll. Let the user set LEXLIB='' to indicate no library needed.
1835 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1836 * README: Likewise.

1898 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
1899 Also check for -Wpointer-arith.
1900 (WGET, WGETFLAGS, tgz-md5, tgz-sha1, bz2-md5, bz2-sha1):
1901 (xdelta-md5, xdelta-sha1, tgz-size, bz2-size, xd-size, rel-check):

1932 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
1933 64-bit preprocessor ints. Check for static initialization of
1934 long long. Remove unnecessary casts.
1936 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1938 * doc/autoconf.texi (Particular Programs): Mention that
1939 @INSTALL@ and @MKDIR_P@ may vary for different output files.

1942 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
1944 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
1945 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
1946 Bill Northcott in
1947 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.

1955 longer supported by Sun.
1957 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
1959 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
1960 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1961 -Wundef -Werror". Problem reported by David Fang in
1962 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

1978 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1979 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1980 this.
1982 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1984 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1985 problems with arg script text that doesn't end in newline, and
1986 with '-e a...'. Problems reported by Ralf Wildenhues.
1988 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1990 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
1991 check for libXt by a check for libX11.
1993 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1996 to last change.
1998 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2000 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
2001 --help' should mention that `--version' outputs configuration
2002 settings. Report by Bruno Haible.
2004 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
2006 Fix test suite failures reported by Pierre in
2007 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
2008 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
2009 the compiler created a file "b.out" when it didn't create anything
2010 at all.

2016 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
2017 in the restoring of the werror flag.
2019 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>

2022 less skeptical about "volatile", after discussion with
2023 Bruno Haible on bug-gnulib.
2024 (Limitations of Usual Tools): Warn about sed stripping
2025 leading white space from text. From Bruno Haible.
2027 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
2029 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
2030 compiler complains about it, even if things works after the
2031 complaint. Problem reported by Peter O'Gorman.
2033 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
2034 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
2035 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
2037 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
2039 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
2040 after -R regardless of host. Patrick Welche reports that this

2049 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2051 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
2052 under AC_C_VOLATILE.
2053 (Volatile Objects): Be a little less skeptical about what
2054 "volatile" means. Derived from thoughts by Ben Pfaff in
2055 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
2057 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2059 * doc/autoconf.texi: Fix some typos.
2061 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2063 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2064 more globally, since the 2006-06-30 patch didn't suffice. Problem
2065 reported by Keith Marshall. Also, don't bother with builddir2,
2066 since it shouldn't be needed any more.
2068 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
2070 * doc/autoconf.texi (Generic compiler characteristics):
2071 Document AC_COMPUTE_INT. Fix wrong statements on Default
2072 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

2077 AC_COMPUTE_INT.
2079 * NEWS: Document change.
2081 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>

2085 * NEWS: Document previous change.
2087 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
2089 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
2090 Require that long long int be at least 64 bits wide. C99 requires
2091 this and enough programs depend on it so we should check for it.
2092 Bruno Haible reports in
2093 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
2094 that long long int is 32 bits wide with some nonstandard compilers.
2095 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
2097 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
2099 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2100 to a nonexistent file, so that we don't have to worry about
2101 a local site configuration that doesn't use /usr/local.
2102 Problem reported by Keith Marshall in
2103 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
2105 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
2107 * doc/autoconf.texi: Be more consistent about using @acronym with
2108 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
2109 quite right (it talked about "OSF/Tru64", even though the
2110 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
2111 and it even mentioned "OSF 4"!) and at this point there's little
2112 reason to talk about OSF any more, since it died in 1994.
2113 (Specific Compiler Characteristics): Simplify example of
2114 negative-size array.
2115 (File Descriptors): Reorder to make the text flow better.
2116 Remove joke about "appreciate the various levels"; I didn't get it.
2117 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
2118 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
2119 (File Descriptors, Limitations of Usual Tools):
2120 Tone down the advice against renaming or removing open files.
2121 (Limitations of Usual Tools): Add a new section, on 'rm'.
2123 2006-06-26 Stepan Kasal <kasal@ucw.cz>
2125 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
2126 -lXt in LIBS, idea from Karsten Hopp; this was due since
2127 this change:
2129 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2130 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2131 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2132 (which belong to Xt, not X itself). See Debian bug 327655.
2134 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2136 * configure.ac (AC_INIT): Bump to 2.60a.
2137 * NEWS: Update.
2139 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2143 * configure.ac, NEWS: Update.
2145 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2147 * config/texinfo.tex: Sync from upstream.
2149 * bin/autom4te.in (handle_traces): Transform the `@S|@'
2150 quadrigraph correctly in traces.
2152 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
2153 Fix typos.
2155 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
2156 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
2157 not defined.
2158 * doc/autoconf.texi (Changed Directory Variables): New node,
2159 to document the whole `datarootdir' business a bit better.
2160 * NEWS: Update.
2161 * tests/torture.at (datarootdir workaround): Extend test.
2162 Prompted by report by Alexandre Julliard.
2164 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
2166 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
2167 when using default mode of IBM C 6 for AIX. Problem and two-line
2168 fix reported by Larry Jones.
2170 2006-06-22 Alexandre Julliard <julliard@winehq.org>
2172 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
2173 about literal '${datarootdir}' if a definition is found in the
2174 output file.
2176 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
2178 * NEWS: Use "M4" rather than "m4" when appropriate.
2179 Problem reported by Eric Blake.
2180 * doc/autoconf.texi: Likewise.
2181 Use @acronym around BSD, GCC, and GNU when appropriate.
2182 (Why GNU M4): Renamed from "Why GNU m4".
2183 (Redefined M4 Macros): Mention that Posix
2184 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
2185 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
2186 to int.
2188 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2190 * bin/autom4te.in (handle_output): Do not forbid the empty
2191 pattern.
2192 * tests/tools.at (autoconf: the empty token): New test.
2194 2006-06-20 Stepan Kasal <kasal@ucw.cz>
2196 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
2197 calls, so that we do not care whether they are LIFO or FIFO;
2198 in the m4_wrap, do not check which diversion is the topmost
2199 one, just check that the stack is balanced at the end.
2200 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
2201 base diversion forever--pop the previous diversion before
2202 opening the new one; consequently, remove the m4_wrap call.
2203 * lib/autotest/general.m4 (AT_INIT): Likewise.
2204 * tests/m4sugar.at: Do not use
2205 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
2207 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
2208 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2210 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
2211 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
2212 Rework example of m4wrap token-pasting trouble so that it doesn't
2213 care whether it's LIFO or FIFO.
2214 Fix some "contrary to"s that are awkward in English.
2216 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2218 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
2219 to `yes' instead of `int$1_t' if the type is found, for more
2220 consistent configure output (where $1 is the number of bits).
2221 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
2222 Suggested by Bruno Haible.
2224 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
2225 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
2226 with system headers. Report by Bruno Haible.
2228 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2230 * config/config.guess, config/config.sub: Sync from upstream.
2232 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2233 in order to avoid picking up an older installed frozen m4sh.m4f.
2234 Besides an outdated shell startup, this could have been created
2235 by an earlier M4 version with incompatible frozen file format.
2237 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2239 * README: Recommend m4 1.4.4 instead of 1.4.3..
2240 * doc/autoconf.texi: Likewise.
2241 (Special Chars in Names): Say that $(.FOO) is portable, as
2242 suggested by Stepan Kasal.
2243 (Installation Directory Variables, Build Directories):
2244 (Automatic Remaking, Subdirectories, Fortran Compiler):
2245 (Making testsuite Scripts, Defining Directories):
2246 Quote variable usages better.
2247 (Making testsuite Scripts): Add clean-local rule to makefile
2248 snippet, by Eric Blake.
2249 (Installation Directory Variables): Fix table item font.
2250 Reword slightly to clarify. Generalize advice about
2251 not using special characters to include all file-related
2252 vars, not just VPATH.
2253 (Special Chars in Variables): Warn about special characters in
2254 $(srcdir) too.
2255 (Assignments): Clarify default-value example as suggested by
2256 Ralf Wildenhues in
2257 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2258 (Special Shell Variables): Note leading ./ or ../, as suggested
2259 by Eric Blake.
2260 (Limitations of Builtins): Under cd, warn about CDPATH.
2261 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2262 Ralf Wildenhues.
2264 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2266 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2267 `@var', for texi2html.
2268 (Systemology): Some more word wrapping, for DVI output.
2269 (autom4te Invocation): The short option for `--melt' is `-M',
2270 not `-m'.
2272 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2274 * doc/autoconf.texi: More formatting and English tweaks,
2275 many suggested by Ralf Wildenhues.
2276 Reword to avoid "@code{...}'s" and the like, since it's ugly
2277 with Emacs info mode. discontents -> woes.
2278 Put a few "will"s back. time stamp -> timestamp.
2279 side-effect -> side effect.
2281 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2283 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2284 Warn about $@ not persisting. Problem reported by Julien Danjou in
2285 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2286 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2287 Mention other special chars, too.
2289 2006-06-14 Eric Blake <ebb9@byu.net>
2291 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2293 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2295 * doc/autoconf.texi: Some systematic minor improvements, as
2296 follows. Use "makefile" when talking about makefiles
2297 generally (which might be named "makefile" or "Makefile" or even
2298 "foo.mk"), "Makefile" when talking about a specific makefile
2299 called "Makefile". This unclutters the text from weird quotes
2300 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2301 values" rather than "@var{foo}s" and similar constructs containing
2302 "}s". Use "Make rules" rather than "Makefile rules". Minor
2303 English-language improvements. Change the prefix "sub-" to "sub"
2304 and "re-" to "re".
2305 Put blank lines around examples more consistently.
2306 Avoid "rather" and "very" as intensifiers.
2307 Avoid "will" as an auxiliary.
2308 (Limitations of Make): Split this node into....
2309 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2310 (Leading _ in Macro Names, Backslash-Newline-Newline):
2311 (Backslash-Newline Comments, Long Lines in Makefiles):
2312 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2313 (obj/ and Make, make -k Status, VPATH and Make):
2314 (VPATH and Double-colon, $< in Explicit Rules):
2315 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2316 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2317 New nodes, resulting from splitup of Limitations of Make.
2318 All cross-references changed. Raise the top node from
2319 a section to a chapter, and all subnodes accordingly.
2320 Redo the introductory wording to match the new organization.
2321 (Installation Directory Variables): Use an example that is
2322 closer to what Autoconf actually does. Mention that VPATH's
2323 value should not contain metacharacters or white space.
2324 (Fortran Compiler): Fix a VPATH bug in an example.
2325 (Leading _ in Macro Names): Mention that this problem is no longer
2326 of practical concern.
2327 (VPATH and Make): Reword the advice to make it clearer
2328 that Autoconf and Automake support VPATH in non-GNU make, but
2329 many packages have bugs in this area.
2330 ($< in Explicit Rules): Refer to Build Directories rather
2331 than using a (non-VPATH-safe) example.
2332 (Automatic Rule Rewriting): Mention the sort of disaster that
2333 can ensue with Solaris-style rule rewriting with VPATH.
2335 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2337 * doc/install.texi (Compilers and Options): Weaken the
2338 suggestion to use GNU make for VPATH builds.
2340 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2341 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2343 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2344 in regular expression.
2346 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2348 * doc/autoconf.texi (Installation Directory Variables):
2349 Drop extra @samp from `@table @samp' item.
2350 (Limitations of Usual Tools): Comment fix.
2351 Do not nest @samp just to point to other table items.
2352 (Writing testsuite.at) <AT_CHECK>: The second argument to
2353 `@dvar' is already @samp'ed.
2354 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2355 do not use @var in the second argument.
2357 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2359 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2360 $as_shell.exe too. Problem reported by Andreas Buening in
2361 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2363 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2365 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2366 `unused variable' compiler warning, for `-Wall -Werror'.
2367 Reported by Jaap Haitsma in
2368 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2370 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2372 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2373 case the compiler dumps core. Problem reported for
2374 OpenServer 5.0.7 by Tim Rice in
2375 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2376 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2377 Likewise.
2379 2006-06-06 Tim Rice <tim@multitalents.net>.
2381 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2382 "ERROR" only shows up in "make check" output if there is an
2383 error.
2385 2006-06-06 Eric Blake <ebb9@byu.net>
2387 * tests/tools.at (automatically allowed tokens): Fix typo.
2389 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2391 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2393 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2394 typically overflows on x86 CPUs, even though the C standard
2395 requires otherwise.
2397 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2399 * configure.ac (AC_INIT): Bump to 2.59e.
2400 * NEWS: Update.
2402 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2404 Version 2.59d.
2406 * config/texinfo.tex: Sync from upstream.
2408 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2409 seen, invoke libtoolize with `--ltdl' argument.
2410 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2411 * NEWS: Update.
2412 Suggested by Eric Blake.
2414 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2416 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2417 reported by Ralf Wildenhues.
2418 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
2420 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2422 * THANKS: Update.
2424 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2426 * doc/autoconf.texi: Modernize some of the references to Solaris.
2428 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2430 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2431 message issued by AC_REQUIRE.
2432 * tests/m4sugar.at: Check m4_require's error message.
2433 * tests/base.at: Check AC_REQUIRE's error message.
2434 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2435 to...
2436 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2437 AT_CHECK_M4.
2438 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2439 `expout' as the last parameter.
2440 * tests/tools.at: Adapt to the above change.
2442 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2444 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2445 information about race-free implementations of mkdir.

2450 * bin/autoconf.as (Usage): Likewise.
2451 * bin/autom4te.in (help): Likewise.
2452 * doc/autoconf.texi (autom4te Invocation): Likewise.
2454 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2456 * NEWS: GNU make now recommended for VPATH builds.
2457 Mention that some macros are now documented to be obsolescent.
2458 * doc/autoconf.texi:
2459 Prefer "current" to "modern" to describe
2460 currently-used (albeit perhaps old-fashioned) hosts.
2461 Mention which ancient features no longer need to be worried about.
2462 setgid -> set-group-ID
2463 setuid -> set-user-ID (these are the Posix terms)
2464 Fix some misuses of "only".
2465 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2466 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2467 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2468 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2469 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2470 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
2471 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
2472 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2473 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2474 Mention that these macros are obsolescent.
2475 (Installation Directory Variables): shall -> should
2476 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2477 Mention that it's now safe to use 3 and 4.
2478 (Limitations of Usual Tools): cp -r is now specified by Posix.
2479 Omit longwinded and obsolescent discussion of cp -f.
2480 Modernize discussion of expr, ls.
2481 (Limitations of Make): Modernize discussion of VPATH builds.
2482 Mention $? as a workaround in some cases.
2483 * doc/install.texi (Basic Installation):
2484 Mention "./configure; make; make install" first. Be more
2485 specific about why this file is generic. Remove unnecessary
2486 parens. Remove misleading "only". Remove obsolete advice
2487 about csh. Don't say "configure" takes awhile; say it
2488 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2489 and CC=c99 rather than CC=c89, as these are blessed by current
2490 Posix. Recommend GNU make if doing a VPATH build.
2492 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2494 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2495 examples involving shell prompts.
2497 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2498 and Paul Eggert <eggert@cs.ucla.edu>
2500 * doc/autoconf.texi (Here-Documents): Add details about the
2501 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2502 use "here-documents" instead of "here documents".
2504 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2506 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2508 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2510 * doc/autoconf.texi (File System Conventions): Warn about ":"
2511 anywhere in directory names.
2513 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2515 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2516 about quoting the case statement, just in case.
2517 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2518 was fixed in ksh93g; reported by Ralf Wildenhues.
2520 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2522 * doc/autoconf.texi (System Services): Do not document
2523 overriding EXEEXT via ac_cv_exeext=ext.
2524 (Particular Programs) <AC_PROG_MKDIR_P>:
2525 Document that ${MKDIR_P} understands --.
2526 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2527 comment.
2529 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2531 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2532 argument with leading hyphen. Problem reported by Paul Eggert.
2534 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2536 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2537 about quoting ac_try: quote all of it, if any of it seems suspicious.
2538 This means we don't have to worry about ${ or sed any more.
2539 Also, double-quote the case statement, to work around misuses via
2540 underquoting as reported by Ralf Wildenhues in
2541 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2542 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2543 undocumented and dangerous macro.
2544 Problem reported by Ralf Wildenhues in
2545 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2547 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2549 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2550 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2551 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2553 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2555 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2556 since evidently some packages rely on the old, broken behavior.
2557 Problem reported by Ralf Wildenhues in
2558 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2559 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2560 pre-2006-05-26 definitions, but leave in the comments that
2561 these macros are dangerous and should not be used.
2562 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2563 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2564 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2565 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2566 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2568 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2570 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2571 the use of 'tr', since this is our only use of 'tr'.
2573 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2574 and Paul Eggert <eggert@cs.ucla.edu>
2576 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2577 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2579 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2581 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2582 the output file in the `${datarootdir}' test.
2584 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2585 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2587 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2588 mention of `datarootdir' in the input file(s), but literal
2589 `${datarootdir}' in the output file, and we haven't warned yet,
2590 then warn as well: the user may have (erroneously) used
2591 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2592 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2593 * tests/torture.at (datarootdir workaround): Extend this test.
2594 * NEWS: Update.
2596 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2597 and Paul Eggert <eggert@cs.ucla.edu>
2599 * doc/autoconf.texi (autoheader Invocation): The first argument to
2600 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2601 alternatives and clear up the language a bit.
2603 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2605 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2606 ac_config_guess, ac_config_sub, ac_configure.
2607 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2608 Fix typo that prevented an unnecessary space from being removed.
2609 Problems reported by Ralf Wildenhues in:
2610 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2612 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2614 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2615 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2616 Don't use the term "thread-safe" to talk about mkdir race
2617 conditions, since the problem is more a process than a thread
2618 issue. Problem reported by Stepan Kasal in:
2619 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2620 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2621 the test for 'install' more closely. Look at MKDIR_P first.
2622 Look in the PATH, and at /opt/sfw/bin.
2623 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2624 Don't bother to try mkdir -p, since we already check mkdir --version;
2625 just look at the version number. (There's no easy way to check
2626 for race-free implementations.)
2627 * tests/tools.at (autoconf: subdirectories): Adjust to above
2628 changes, since MKDIR_P now might end in "/mkdir -p".
2630 * doc/autoconf.texi (autoheader Invocation): Mention that the
2631 first arg of AC_DEFINE_UNQUOTED must be a literal.
2632 Problem reported by Ben Pfaff in
2633 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2635 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2636 * doc/autoconf.texi (Special Chars in Variables): New section.
2637 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2638 (Installation Directory Variables): Quote $(datadir) better.
2639 (Limitations of Builtins): Describe some of eval's trickiness.
2641 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2642 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2643 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2644 in front of every arg, not just trailing args. Quote apostrophes.
2645 (_AC_EVAL_ECHO): New macro.
2646 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2647 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2648 removed.
2649 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2650 exposed by quoting of eval argument. Put the command on line line
2651 so it logs better.
2652 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2653 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2654 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2655 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2656 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2657 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2658 Use eval more safely.
2659 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2660 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2661 to be replaced.
2662 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2663 lines, exposed by quoting of eval argument.
2665 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2666 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2668 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2669 initialization of `ac_cv_exeext', do not override it if it was
2670 already set, unless it was set to `no', for compatibility with
2671 Autoconf-2.13, and comment this.
2672 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2673 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2674 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2675 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2676 Document that this test may be overridden by setting
2677 `ac_cv_exeext'.
2679 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2681 Revert these two patches:
2683 2006-04-06 Eric Blake <ebb9@byu.net>
2684 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2685 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2686 2006-04-01.
2688 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2689 Clean up _AC_COMPILER_EXEEXT* macros.
2690 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2691 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2692 ac_file to the name of the default output file and call
2693 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2694 initial `rm' of the candidate files...
2695 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2696 the same list in subsequent `rm' calls, and for the temporary
2697 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2698 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2699 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2700 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2701 no longer needed) by libtool. Make it a cache check.
2702 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2703 copied here by mistake.
2704 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2705 _AC_COMPILER_EXEEXT.
2706 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2707 _AC_COMPILER_OBJEXT directly.
2708 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2710 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2712 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2713 Fix description of how the buggy `sed' works.
2715 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2717 Sync from Automake:
2719 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2720 ENOLCK. Only mention `make -j' when applicable. Only raise
2721 fatal errors when `make -j' is involved. Improve error message.
2723 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2725 * doc/autoconf.texi (Here-Documents): We now know more about
2726 the variable expansion in here documents bug.
2727 Thanks to Tim Rice and Stepan Kasal.
2729 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2730 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2732 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2734 * tests/autotest.at (Multiline command from M4 expansion):
2735 No failure to be expected if the shell quotes newlines in
2736 commands in the `set -x' output. Report by Tim Rice.
2737 * THANKS: Update.
2739 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2741 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2742 expansion in the here-documents used by config.status, as that
2743 runs afoul of the Korn shell version M-12/28/93d bug described in
2744 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2745 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2746 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2748 2006-05-23 Jim Meyering <jim@meyering.net>
2750 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2751 Fix typo introduced with 2006-04-02 change. It reversed the sense
2752 of the test.
2754 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2756 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2757 ac_dB slightly, to save bytes in the script.
2758 Max out at 50 lines, rather than 96; this is more likely
2759 (though not guaranteed) to avoid obscure 'sed' failures.
2761 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2763 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2764 `tr -d -' as bad option argument. Work around this by deleting
2765 an unrelated character.
2766 Report by Tim Rice <tim@multitalents.net>.
2768 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2769 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2770 Stepan Kasal <kasal@ucw.cz>
2772 * doc/autoconf.texi (Particular Programs): Do not promise that
2773 we always prefer the GNU version of the program, and that we
2774 search according to PATH; both rules can have exceptions.
2775 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2776 AC_PROG_SED. Move descriptions of limitations
2777 to the Limitations of Usual Tools section.
2778 (Limitations of Usual Tools) <sed>: Mention script length
2779 limitations with Solaris /usr/ucb/sed.
2780 <grep>: Fix wording for empty alternative. Mention that -c and
2781 -l should not be combined, and that -E and -F should not be
2782 combined.
2784 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2785 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2787 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2788 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2790 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2792 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2793 AC_DEFINE is now passed to m4_pattern_allow.
2794 * NEWS: Mention that; likewise for AC_SUBST.
2795 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2796 the parameter to m4_pattern_allow.
2797 * tests/tools.at: Add a check for that.
2799 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2801 * lib/autoconf/status.m4: Fix typos.
2803 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2805 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2806 only the files that this macro generates.
2808 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2810 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2811 the HP-UX sed limitation of 99 commands, labels do not count.
2812 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2813 in the comment.
2814 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2816 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2818 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2819 Import the following fix from coreutils:
2821 2006-01-13 Jim Meyering <jim@meyering.net>
2823 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2824 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2825 not double-quote uses of that variable, to accommodate the rare
2826 case in which getmntent is available in none of the libraries
2827 checked. This happens at least on FreeBSD 5.0.
2829 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2831 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2832 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2833 some other programs unwisely rely on these undocumented vars.
2834 But put in warning comments about them.
2835 Problem reported by Ralf Wildenhues in
2836 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2837 * NEWS: Document that these variables are intended to go away.
2839 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2841 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2842 and set the language to C++ (analogous to the equivalent Fortran
2843 tests).
2845 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2846 * doc/autoconf.texi (C++ Compiler): Document it.
2847 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2848 * NEWS: Update.
2850 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2852 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2853 that caused config.status to generate 100-command sed scripts; the
2854 portable limit is 99.
2856 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2858 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2859 variable `ac_d' instead of `d' to avoid infringing namespace.
2860 Report by Ralf Menzel.
2862 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2864 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2865 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2866 * tests/tools.at (autoconf: subdirectories): New test, taken from
2867 the corresponding problem report by Ralf Wildenhues in:
2868 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2870 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2871 Quote some uses of shell variables if they might suffer unexpected
2872 globbing. This doesn't fix all instances of quoting problems that
2873 I found, just the easy ones that look safe.
2874 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2875 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2876 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2877 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2878 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2879 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2880 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2881 Likewise.
2882 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2883 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2885 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2887 * bin/autoreconf.in ($help): Reword according to the manual.
2888 Suggested by Olly Betts.
2890 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2891 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2893 * bin/autoreconf.in: Pass the directory argument to
2894 `require_configure_ac'. Fix comment.
2895 * tests/torture.at (Configuring subdirectories): Expose this.
2896 Reported by Olly Betts.
2898 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2900 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2901 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2902 Automake as follows:
2904 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2905 `$configure_in' instead of `configure.in', to preserve
2906 directory component.
2908 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2910 * config/config.guess, config/config.sub, config/texinfo.tex,
2911 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2913 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2915 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2916 test for C99 conformance; (bool) 0.5 is an integer constant
2917 expression, but (bool) -0.5 is not. Problem reported by Fedor
2918 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2920 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2922 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2923 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2924 Warn about obsolete install-sh files. Remove stray sentence
2925 fragment and fix cross reference.
2926 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2927 install -d; this undoes the 2006-05-10 change.
2928 (MKDIR_P): Mark with AN_MAKEVAR.
2929 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2930 that we don't require $INSTALL to be thread-safe. Move comments
2931 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2932 of AC_PROG_INSTALL. Output a message saying that we're checking
2933 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2934 MKDIR_P instead of AC_SUBST.
2935 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2936 Special magic for MKDIR_P, too.
2937 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2938 a dnl.
2939 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2941 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2943 Sync from Automake, as follows:
2945 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2946 * config/install-sh: Initialize IFS, so field splitting isn't
2947 turned off later.
2948 * config/mkinstalldirs: Likewise.
2949 * config/missing: Remove superfluous quotes. Replace all uses of
2950 `[' by `test', for consistency, and for..
2951 * config/missing (sed_minuso, sed_output): New variables.
2952 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2953 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2954 Fixes `missing' to detect `--output' for help2man. Fixes
2955 PR automake/483. Report by Dennis J. Linse.
2956 (autom4te): Document in `missing --help'.
2958 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2960 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2961 * config/install-sh: Don't use 'path' to talk about file names,
2962 as per GNU coding standards. Close a race condition reported by Ralf
2963 Wildenhues and Stepan Kasal. There is still a race condition
2964 on hosts that predate Posix 1003.1-1992, but we can't help this.
2965 Don't mishandle weird characters like space on pre-Posix hosts.
2966 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2967 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2968 AC_PROG_MKDIR_P from AS_MKDIR_P.
2969 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2970 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2971 earlier editions are not (including Automake 1.8.3).
2972 Do not suggest mkinstalldirs for thread-safety.
2973 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2974 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2975 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2976 presence of special characters and race conditions.
2977 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2978 in Autoconf's name space.
2980 2006-05-10 Bruno Haible <bruno@clisp.org>
2981 and Paul Eggert <eggert@cs.ucla.edu>
2983 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2984 from Automake with minor changes.
2985 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2987 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2989 * config/install-sh: Update to Automake CVS version, as follows:
2990 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2991 * lib/install-sh: Simplify the expr implementation of dirname.
2992 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2993 * lib/install-sh: Handle --, and diagnose unknown options.
2995 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2997 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2998 `./autom4te' to create `./testsuite', since the `all' target
2999 will ensure its presence, but `installcheck' should not create
3000 the uninstalled wrappers.
3002 * tests/torture.at (Unusual Automake input files): Skip if we
3003 detect automake < 1.8.
3005 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3007 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3008 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3009 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3010 * NEWS: Update.
3012 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3014 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3015 munge (multiple) white space and other oddities.
3016 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3017 single quotes in variable assignment.
3018 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3019 and similar failures by adding multiple spaces, tabs, and other
3020 special characters.
3021 Report and different test suggested by Francesco Romani
3022 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3024 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3025 single quotes, we only need to search for single quotes; this
3026 both simplifies the search pattern, and makes us less
3027 susceptible to `echo' variations for arguments not containing
3028 single quotes.
3029 (_AC_ARG_VAR_VALIDATE): Likewise.
3031 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3033 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
3034 `$*' and IFS concatenation issue with traditional shells and
3035 bash-2.04. Report by Seanster@Seanster.com.
3037 2006-05-03 Bruno Haible <bruno@clisp.org>
3039 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
3040 precisely which Mac OS X versions have the od problem.
3042 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3044 * doc/autoconf.texi: Use @option systematically.
3046 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3047 and Bruno Haible <bruno@clisp.org>
3049 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
3050 about 'od'.
3051 (Integer Overflow): Mention the special case of integer division
3052 overflow.
3054 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3056 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
3057 traditional shells like the Solaris one that do not use the
3058 first IFS character for assembling `$*'.
3059 Prompted by a related report from autoconf_bug@nro.ca.
3061 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
3062 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3064 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
3065 Mention more problems with the -e option.
3067 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3069 * NEWS: Typo.
3070 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
3072 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
3073 in URLs to improve DVI formatted output (requires texinfo 4.6).
3074 (System Services, Systemology, Shellology): Likewise.
3075 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
3076 output.
3078 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
3079 continuous text.
3080 (Runtime): Fix macro argument names to match description:
3081 `action-if-found' -> `action-if-true' and similarly.
3082 (Obsolete Macros): Likewise.
3083 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
3084 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
3085 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
3087 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3089 * doc/autoconf.texi (Limitations of Make): Clean up markup.
3091 * ChangeLog: Typo.
3092 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
3093 DVI output.
3095 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3100 * tests/local.at: Likewise.
3102 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
3104 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
3105 (Integer Overflow, Null Pointers, Buffer Overruns):
3106 (Floating Point Portability, Exiting Portably): New sections.
3107 (Writing Test Programs): Fix some langauge. Recommend exiting
3108 with status 1, not merely nonzero. Clarify exit declaration.
3109 (Run Time): Move C exit status stuff to new Exiting Portably section.
3110 (Systemology): Mention Posix and levenez. Update v7 reference.
3111 (Portable Shell): Mention the Posix shell.
3113 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3115 * bin/autoconf.as (me): Replace by as_me.
3117 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
3119 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
3120 since as_me isn't set yet.
3122 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3124 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
3125 a few minor bugs in this area.
3127 * doc/autoconf.texi (Programming in M4sh): Comment out the
3128 documentation of AS_BASENAME, for now.
3129 (Shell Substitutions): Do not use AS_DIRNAME in an example.
3130 (Limitations of Builtins) <basename>: Do not refer to
3131 AS_BASENAME.
3132 * bin/autoconf.as (me): Don't use AS_BASENAME.
3133 (dir): Remove the unused variable.
3134 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
3135 AS_DETECT_REQUIRED. All uses changed.
3136 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
3137 All uses changed.
3138 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
3139 (AS_BASENAME): Use "basename --" to protect against leading "-".
3140 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
3141 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
3142 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
3143 (_AS_DIRNAME_PREPARE): Likewise.
3144 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
3145 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
3146 (AS_DIRNAME): Use "dirname --".
3148 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3150 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
3151 of "run time" and "run-time" changed to "runtime", for consistency.

3158 with more accuracy and detail.
3160 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3162 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
3163 Archive is not officially `GNU' any more. Update URL.
3164 (Defining Directories): Likewise
3165 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
3167 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3169 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
3170 newline from the `trap' code to finish `config.log'; the NetBSD
3171 /bin/sh resets the exit status after an empty command, as
3172 documented in doc/autoconf.texi.
3173 Reported by Dalibor Topic <robilad@kaffe.org>.
3175 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
3177 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
3178 Suggested by Bruno Haible.
3180 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
3182 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
3183 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
3184 Instead, just list the shells that we know work.
3185 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
3186 changed. Be more cautious about the _cv_ variable.
3187 * tests/tools.at (Syntax of the shell scripts): Check the
3188 _cv_ variable once, at first, to avoid an internal autoconf error
3189 when sh -n does not work.
3191 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3193 * lib/Autom4te/FileUtils.pm: Sync from Automake.
3195 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
3197 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
3198 use ">&-" since we're only 99.999% sure that this is portable,
3199 and since the MinGW bug is fixed in a different way.
3200 * lib/autotest/general.m4 (AT_INIT): Likewise.
3202 2006-04-16 Stepan Kasal <kasal@ucw.cz>
3204 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
3205 before opening config.log, to avoid hitting a bug on MinGW.
3207 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
3209 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
3210 AS_MESSAGE_LOG_FD before reopening it onto the log file.
3211 This works around a MinGW bug reported by Eric Paire.
3212 Make sure that all writes to the log file append to it,
3213 rather than possibly losing data.
3214 * lib/autotest/general.m4 (AT_INIT): Likewise.
3216 2006-04-14 Stepan Kasal <kasal@ucw.cz>
3218 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
3219 description.
3221 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3223 * NEWS: Update.
3225 * configure.ac (AC_INIT): Bump to 2.59d.
3227 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3229 Version 2.59c.
3231 * Makefile.maint (news-date-check): Do not require a leading `*'
3232 before the release date in NEWS.
3234 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3235 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3237 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3238 the instantiated file do not contain the string 'datarootdir'
3239 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3240 @mandir@, replace the reference '${datarootdir}' by the value.
3241 * tests/torture.at (datarootdir workaround): New test.
3242 * NEWS: Advertise this temporary fixup.
3243 Based on a patch by Bruno Haible, reported and analyzed by
3244 Paul Eggert and Noah Misch.
3246 2006-04-12 Eric Blake <ebb9@byu.net>
3248 * tests/autotest.at (Debugging a failed test): Fix comment.
3250 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3252 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3253 all the changes since 2006-04-07.
3255 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3257 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3258 succeeded, but `ln -s file dir' failed, take care to remove the
3259 leftover target before the next test, to prevent its spurious
3260 failure; also make sure `ln file dir' works before selecting it.
3261 Thanks to Keith Marshall for pointing this out.
3262 * THANKS: Update.
3264 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3265 assignments in `at_debug_args', so that we put them correctly
3266 in the `run' script.
3267 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3268 Reported by Eric Blake.
3270 2006-04-11 Eric Blake <ebb9@byu.net>
3272 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3273 top-level tests after micro-suite has been run. Used in...
3274 (Debugging a successful test, Debugging script and environment),
3275 (Debugging a failed test): ...these new tests. The first of these
3276 is fixed by...
3277 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3278 macro, split out from...
3279 (AT_INIT): ...here, so that using -d also generates a run script.
3280 Document that -d inhibits top-level logging.
3281 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3282 inhibits top-level logging; debug scripts are created.
3284 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3285 check.
3286 * tests/autotest.at (Empty test, Empty check): New test to check it.
3288 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3289 from gcc.
3291 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3293 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3294 the files if a problem appears. Make the empty *.at files
3295 read-only, too. Proposed by Ralf Wildenhues.
3297 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3299 * config/Makefile.am: Add comment to force updated Makefile.in.
3301 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3302 space only patch to this file, this patch causes the Makefile.in
3303 files that include freeze.mk to be updated, and thus have a
3304 newer time stamp again, which in turn makes a pristine CVS
3305 checkout have correct time stamps.
3307 * Makefile.maint (cvs-sv): New macro, to be used..
3308 (config.guess-url_prefix, config.sub-url_prefix)
3309 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3310 point to CVS text checkout of Gnulib files.
3311 (copyright-check): Bump current year.
3312 (announcement): Do not hard-wire `./announce-gen'.
3313 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3314 correctly.
3315 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3316 `chmod +x'.
3317 (wget_files): Update config.guess, config.sub, texinfo.tex by
3318 `wget-update', now that their URLs work again.
3320 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3322 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3323 Problem noted by Paul D. Smith.
3325 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3327 * doc/autoconf.texi: Remove unused words from word list.
3328 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3329 .x-sc_trailing_space: New files.
3331 * doc/standards.texi: Sync from gnulib.
3333 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3334 `LIBOBJDIR' as experimental.
3336 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3337 with a target directory; it's internally implemented as `cp'
3338 anyway, but since Autoconf advertises the possibility to use
3339 a target directory when LN_S is `ln -s', we need to find out.
3340 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3341 analyzed by Keith Marshall <keith.marshall@total.com>.
3343 * THANKS: Update.
3345 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3347 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3348 confdefs.h as-is. In general, if it has backslash-newline or the
3349 like, then it doesn't work either to sort or to remove empty
3350 lines.
3352 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3354 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3356 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3358 * lib/autom4te.in (Automake-preselections): Preselect
3359 _AM_SUBST_NOTMAKE.
3361 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3363 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3364 apostrophe within a single-quoted string, as this is the usual
3365 tradition and is easier to read than '"'"'. Don't rely on the
3366 shell treating "$/" like '$/'. Use a more-consistent indenting
3367 style for the trap.
3369 2006-04-09 Eric Blake <ebb9@byu.net>
3371 * tests/autotest.at (Backquote command substitution),
3372 (Multiline backquote command substitution): Remove mistaken
3373 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3374 applied...
3375 (Parenthetical command substitution, Multiline parenthetical
3376 command substitution): here.
3378 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3380 Import macros from gnulib (often changing their name).
3382 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

3394 (Pointers): Add Gnulib URL.
3395 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
3396 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3397 Gnulib section.
3398 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
3399 suggest a #define rather than a typedef for _Bool, and mention
3400 Gnulib rather than trying to substitute stdbool code.
3401 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
3402 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
3403 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
3404 AC_STRUCT_DIRENT_D_TYPE.
3405 (Particular Types): Mention stdint.h and inttypes.h as standard
3406 headers too.
3407 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3408 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
3409 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
3410 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
3411 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3412 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3413 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3414 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3415 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3416 (Coding Style). Don't mention m4_expand_once.
3417 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
3418 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
3419 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
3420 (AC_CHECK_FUNCS): Use it.
3421 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.

3424 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
3425 (AC_HEADER_ASSERT): New macro.
3426 (AC_HEADER_STDBOOL): Don't assume "#error" works.
3427 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
3428 Catch a bug in an HP-UX C compiler.
3429 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
3430 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
3431 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
3432 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
3433 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
3434 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
3435 New macros.
3437 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
3438 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
3440 2006-04-08 Stepan Kasal <kasal@ucw.cz>
3442 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
3443 of the warning introduced by the 2001-08-28 change.
3445 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
3446 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3448 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
3449 variables shall be overriden by the cache.
3450 * tests/torture.at (AC_ARG_VAR): Test also with a first value
3451 that contains braces.
3453 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3455 Revert the patch from 2006-04-01 and only improve
3456 _AS_DETECT_BETTER_SHELL:
3458 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3459 skip nonexistent directories.
3460 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3461 only shell candidates which exist.
3462 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3463 * lib/autotest/general.m4 (AT_INIT): No need to give three
3464 parameters to _AS_PATH_WALK.
3466 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3467 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3469 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3470 distinguish m4sugar macros.
3471 * tests/tools.at (autoupdating with aclocal and m4_include):
3472 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3473 test case by Noah Misch <noah@cs.caltech.edu>.
3475 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3477 Revert my change from 2006-03-17, in other words:
3478 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3479 and DUALCASE=1.
3480 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3481 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3482 it is set.
3484 2006-04-07 Eric Blake <ebb9@byu.net>
3486 * doc/autoconf.texi (Programming in M4sh): Document that
3487 AS_MKDIR_P exits the script on failure.
3488 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3490 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3492 * config/elisp-comp, config/install-sh, config/mdate-sh,
3493 config/missing, config/mkinstalldirs: Sync from Automake.
3495 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3496 from Automake.
3498 * doc/make-stds.texi: Sync from gnulib.
3500 2006-04-06 Eric Blake <ebb9@byu.net>
3502 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3503 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3504 2006-04-01.
3506 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
3507 Eric Blake <ebb9@byu.net>,
3508 Paul Eggert <eggert@cs.ucla.edu>,
3509 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3511 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3512 whether `set' quotes correctly: redirect stderr of the tested
3513 `set', and use a subshell, for Ultrix; use `sed' instead of
3514 `grep' for zsh `set' which may write binary output; match only
3515 at the beginning of a line, to avoid false positives.
3516 In order to avoid false positives by unrelated variables with
3517 multiline content, put the dump algorithm in a subshell and
3518 unset all variables containing newlines (except some which are
3519 special to the shell). Warn about cache variables that are
3520 unset.
3522 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3524 * config/config.guess, config/config.sub, config/texinfo.tex:
3525 Sync from upstream.
3527 * tests/mktests.sh: Reword comments.
3529 * tests/mktests.sh: Only skip internal macros starting with
3530 `_AC_' or `__AC_'. Noted by Stepan Kasal.
3531 Update exclusion lists for the test suite to this end:
3532 (AC_ARG_VAR): Do test this now.
3533 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3534 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3535 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3536 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3538 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3539 shell issue with double-quoted command substitutions of native
3540 commands.
3541 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
3542 Marshall.
3544 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
3545 no file matches the glob, discard the warning, set `nullglob'.
3546 (syntax-check): Likewise.
3547 (sc_cast_of_x_alloc_return_value): Likewise.
3548 (sc_cast_of_alloca_return_value, sc_error_exit_success)
3549 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
3550 (m4-check): Likewise.
3551 (sc_system_h_headers): Do not print rule on execution.
3552 (sc_tight_scope): Do not fail for non-existing `src' directory.
3553 (sc_changelog): Skip the Copyright footer.
3554 * lib/autoconf/lang.m4: Remove trailing space.
3556 * lib/autoconf/status.m4: More replacements to
3557 <tab><space> where this makes sense.
3559 2006-04-06 Stepan Kasal <kasal@ucw.cz>
3561 * tests/Makefile.am (maintainer-check-posix):
3562 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
3564 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
3565 ac_config_<foo>s again, sometimes normalized, sometimes not.
3566 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3567 (AC_CONFIG_COMMANDS): Do not do so here.
3568 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3569 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3570 2005-07-25 rewrite. Noticed by Noah Misch.
3572 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3573 _AC_PRESERVE_HELP_ORDER, ...
3574 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3576 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3577 inside m4_expand_once; it is redundant.
3579 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3580 for --help from Cygnus `configure.'
3582 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
3584 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
3585 on a patch proposed by Ralf Wildenhues.
3587 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3589 * lib/autoconf/status.m4: Replace <space>''<tab> with
3590 <tab><space> where this makes sense.
3592 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
3593 Noah Misch <noah@cs.caltech.edu>
3595 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3596 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3597 * doc/autoconf.texi (Help Formatting): New node.
3598 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3600 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3602 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3603 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3604 lib/autoconf/types.m4, lib/autotest/general.m4,
3605 tests/mktests.sh, tests/torture.at: White space cleanup:
3606 remove some SPACE before TAB, or add quoting ('' or @&t@).
3608 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
3610 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
3612 2006-04-05 Eric Blake <ebb9@byu.net>
3614 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
3615 empty test suite works.
3616 * tests/autotest.at (Empty test suite): Remove xfail.
3618 2006-04-05 Noah Misch <noah@cs.caltech.edu>
3620 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
3621 TAGS to ac_config_<foo>s.
3622 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
3623 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
3624 normalizing it, consistent it with previous releases.
3625 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3627 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3629 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3630 Use simplified args that Eric Blake originally suggested.
3632 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3634 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3635 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3636 Use 'comm' rather than N instances of grep; this also fixes a bug
3637 whereby substrings were incorrectly matched, causing us to not
3638 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3639 (exclude_list): Exclude empty macros.

3725 ac_file to the name of the default output file and call
3726 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3727 initial `rm' of the candidate files...
3728 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3729 the same list in subsequent `rm' calls, and for the temporary
3730 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3731 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3732 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3733 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

3813 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3814 switch all of them on and of when necessary. Fixes the bug when
3815 m4sugar macros (e.g., m4_define) were expanded after the first
3816 automatic update (e.g., after AC_PREREQ or AC_INIT).
3818 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

4020 example. Do not emphasize `$%', it is hardly new and special.
4021 Reported by Edouard Bechetoille <ebecheto@ens-lyon.fr>.

4051 the obsolescent AC_HEADER_STDC.
4052 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs

4070 HP-UX sed is 99 commands, not 100.
4071 (_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
4072 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
4073 newline for portability.
4074 * tests/torture.at (Torturing config.status): Also test 100

4568 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4570 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4571 calls, so that the final expansion of this macro is shorter.
4572 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4573 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4574 the cleanup there. Use AS_VAR_* macros, to be more general.
4575 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4577 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4579 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

4597 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4599 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4600 in the example. Reported by Bruno Haible.
4601 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4602 "if $undefined_var;" succeeds with my shell.
4604 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4605 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4606 but change the m4_divert_text to m4_divert_once.
4608 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4610 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4611 Work around bug in Solaris /usr/xpg4/bin/awk.
4612 The bug is present in at least Solaris 8 through 10.
4614 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4616 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4617 some evil values and relying on the fact that $* concatenates the
4618 parameters by the first character from IFS.
4620 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4621 Stepan Kasal <kasal@ucw.cz>

4624 first header appears, define AH_HEADER.
4625 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4626 Update limitations about when to call AC_CONFIG_HEADERS.
4627 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4628 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4629 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4630 ``Configuration Actions''; fix their index entries.
4632 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4633 options correctly. Process N-M as M-N if M is smaller than N.
4634 Process ranges correctly so that N-N will run only N.
4635 Sort and uniquify the tests that will be run. If there is more
4636 than one test, reinsert the banners for the tests.

4642 before passing the macro name to AH_TEMPLATE.
4644 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4645 now opens log after option processing; in particular, --version
4646 and --help do not touch config.log.

4663 Prepend to LIBS, not append, in examples.
4665 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4667 When building in place, set srcdir="."; suggested by Tim Van Holder.
4669 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4670 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4671 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4672 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

4686 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4687 add "2>&1"; gzip 1.2.4 prints help on stderr.
4689 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4691 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4692 was pushdef'ed twice while popped only once. Push it only once.
4693 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4695 2005-07-26 Stepan Kasal <kasal@ucw.cz>

4704 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4705 "<tab>" in comment, so that the point is understandable.
4707 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4709 Rewrite substantial part of lib/autoconf/status.m4.
4710 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4711 and CONFIG_COMMANDS are not processed in four separate loops.
4712 Instead, there is one main loop. This alows that the common code
4713 is expanded only once, thus config.status (and configure) is smaller.
4715 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4716 the AC_LIST_FILES and cousins macros are no longer used.
4718 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4719 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4720 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4721 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4722 contain the initialization, nor the for loop, nor the associated
4723 commands; all these go to ...
4724 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4725 _AC_OUTPUT_CONFIG_STATUS.
4726 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4727 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4728 (_AC_OUTPUT_FILE): The creation of the sed script ...
4729 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4730 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4731 _AC_OUTPUT_MAIN_LOOP.
4732 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4733 _AC_CONFIG_COMMANDS): Use ...
4734 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4735 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4736 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4737 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4738 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4739 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4740 ... new macros.
4741 (_AC_CONFIG_UNIQUE): Update.
4742 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4743 Replaced by this ...
4744 (_AC_LIST_TAGS): ... new common macro.
4745 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4746 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4747 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4748 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4749 this didn't belong to the `config commands' section.
4750 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4751 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4752 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4753 to the `config commands' section either.
4754 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4755 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4757 ... and many changes to the comments nearby.
4759 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4760 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4761 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4762 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4763 (#define header templates): The comment at the top of the generated
4764 header now includes the name(s) of the source file(s).
4766 Several unrelated small changes:
4768 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4769 parameter to AC_DIAGNOSE.
4770 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4771 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4772 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4773 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4774 with AU::AC_OUTPUT.
4775 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4776 in AC_OUTPUT doesn't double-quote it either.
4777 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4778 parameters.
4780 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4782 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4783 versions of Portland Group compiler produce single- and double-quoted
4784 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4785 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4787 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4789 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4790 This is a corrected version of yesterday's patch.
4792 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4794 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4795 path, too; insert a "===" to emphasize the line.
4797 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4798 ac_cv_build_alias to ac_build_alias.
4799 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4801 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4802 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4803 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4804 (AC_ARG_VAR): ... here.
4805 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4806 target_alias.
4808 Keep a list of all precious variables and process them with one simple
4809 for loop, instead of expanding all commands, or, OTOH, complicated
4810 processing of output of "set".
4811 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4812 variable names in new macro...
4813 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4814 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4815 a loop to assign all ac_env_* and ac_cv_env_* variables.
4816 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4817 to INIT_PREPARE.
4818 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4819 its value to shell variable ac_precious_vars and call
4820 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4821 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4822 _AC_ARG_VAR_VALIDATE.
4824 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4825 and the AC_SUBSTs ...
4826 (AC_INIT): ... here.
4828 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4829 the ac_subst_files section in config.log.
4831 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
4833 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

4842 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4843 They are generated by the Tru64 v5.1B shell.
4845 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4847 Fix my changes from 2005-07-01; reported by Noah Misch.
4848 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4849 description, the macro now accepts only a single tag.
4850 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4852 Fix cases when the varsions of Autoconf and Autotest don't match.
4853 Reported by Noah Misch.
4854 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4855 at_top_builddir, for compatibility with older autotest.
4856 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4857 is not set, use at_top_builddir, for compatibility with older
4858 versions of autoconf.
4860 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4862 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4863 Problem reported by Patrick Welche.
4865 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4867 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4868 sed substitution command, so that we allow | in program prefixes
4869 and program suffixes. (& is a problem anyway; we're not fixing
4870 that here.)
4871 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4872 configure_input, top_builddir, srcdir, etc.
4873 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4874 PATH_SEPARATOR in AUTOTEST_PATH.
4876 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4878 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4879 for loop over config.site files using `set', to allow
4880 directory names containing IFS characters.
4882 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4884 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4885 directories with weird names. Apparently some people like living
4886 on the edge. However, improve the test that "pwd" actually does
4887 report a name for the working directory.
4888 * NEWS: Remove the claim that we test for funny chars in dir names.
4890 2005-07-01 Stepan Kasal <kasal@ucw.cz>

4903 (Generic Functions): Mention the Gnulib project.
4904 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4906 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4907 document to output the default config_* lists to config.status.
4908 Don't recognize option --file, if the functionality is not there.
4909 Likewise for --header; moreover, recognize --he and --h as shortcuts
4910 for --help in that case.
4912 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4913 matches the order of execution. No code changed.

4934 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
4935 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4936 (AC_SUBST): Call it.
4937 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4938 the directory specific variables; but don't call it for configure_input.
4940 2005-06-28 Derek Price <derek@ximbiot.com>
4942 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4943 addition.
4945 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4947 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4948 directory have inherent problems with special characters like spaces,
4949 due to limitations in Make syntax. Problem reported by Alexandre
4950 Duret-Lutz.
4951 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4964 from Justace Clutter.
4965 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4966 variable into diagnostic. Make the diagnostic an error, not a warning,
4967 because we really don't support spaces and suchlike in dir names.
4968 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4969 Don't worry about backslashes in srcdir; it can't happen now.

4971 Simplify ac_optarg handling.
4972 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

4980 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4982 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4983 that '\|' is not allowed in BREs; recommend using newline separated
4984 list of patterns instead of multiple -e options.
4986 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4988 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4994 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4996 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4997 b, t, r, w commands require single space, while : cannot have any.
4998 (Special Shell Variables): Fix sed code this in the example.
4999 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
5000 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
5002 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
5003 expand to the empty list. Don't use two pairs of m4_changequote,
5004 it's not necessary.
5006 2005-06-20 Derek Price <derek@ximbiot.com>
5008 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
5010 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
5012 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
5013 * doc/autoconf.texi:
5014 Don't mention Solaris versions so much, if a
5015 problem is common to all extant versions of Solaris. Say "SunOS
5016 4" instead of "SunOS" for SunOS 4.
5017 (awk): Mention more of the limitations of traditional Awk.
5018 (cat): Don't talk about cat -v.
5020 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
5022 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
5023 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
5024 but the implementation is entirely different and is designed
5025 to be compatible with glibc strverscmp.
5026 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
5028 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
5029 on Mac OS X 10.4 reported by Peter O'Gorman in:
5030 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
5031 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
5032 Use shell builtins rather than 'expr', to work around expr bug.
5034 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
5036 * doc/autoconf.texi: "filesystem" -> "file system".
5037 "behaviour" -> "behavior".
5038 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
5039 * lib/autoconf/general.m4: Omit blank after ":" sed command,
5040 as per POSIX.
5041 * lib/m4sugar/m4sh.m4: Likewise.
5042 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
5043 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
5045 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
5046 (.x.1): Ignore the time stamp in the .TH line when deciding whether
5047 to update the man page. That way, we don't have to check in new
5048 man pages every month.
5050 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
5051 quotes and backslashes. Patch from Derek Price.

5056 AS_TR_SH.
5058 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
5060 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
5061 -u, since it outputs chatter if the input files are the same.
5062 Problem reported by Ralf Menzel.
5064 2005-06-08 Derek Price <derek@ximbiot.com>
5066 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
5067 renaming them since they are about to be redefined anyhow.
5069 2005-06-08 Derek Price <derek@ximbiot.com>
5071 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
5072 redefined M4 macros to this node. Document m4_include & m4_sinclude.
5073 Move m4_undefine to alphabetical order.
5075 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
5077 * README: Recommend GNU M4 1.4.3 or later.
5078 * doc/autoconf.texi (Introduction): Likewise.
5079 Reword to avoid some formatting glitches.
5080 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
5081 Clarify explanation of HP compiler bug.
5082 Redo example output tp match current CVS snapshot.
5083 Use @example.org in email addresses when the examples
5084 might get inadvertently cut-and-pasted into user code.
5085 Remove example of autom4te usage that doesn't seem to work now.
5086 Use modern AC_INIT (except when the example is meant to be
5087 shown with Autoconf 2.13).
5088 Update ksh info for Solaris 9 and later.
5089 KB -> kB.
5090 Modernize description of Automake versions a bit.
5091 Don't claim a future version of Autoconf is near.
5092 * doc/install.texi: Reword to avoid some formatting glitches.
5094 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5096 * doc/autoconf.texi: Add [] to examples, so that the manual
5097 follows its own advice about quoting better.
5098 Reword to avoid some formatting glitches.
5099 * doc/installt.exi: Reword to avoid some formatting glitches.
5101 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
5102 Tru64 ksh pattern matching bug. Reported against Libtool by
5103 Albert Chin <libtool@mlists.thewrittenword.com> and
5104 Nicolas Joly <njoly@pasteur.fr>.
5106 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5108 m4_cdr of one-member list was [[]] (one-member list containing an
5109 empty string) instead of [] (an empty list. Callers were skewed to
5110 match this misbehaviour. As a consequence of this:
5111 - m4_foreach([x], [], [foo]) expanded to `foo', while
5112 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
5113 This bug has been fixed:
5115 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
5116 expand to an empty string; print error msg if called without
5117 an argument list.
5118 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
5119 misbehaviour; handle [] and [[]] correctly.
5121 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5123 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
5124 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
5125 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
5127 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
5129 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
5130 swallow records with more than 99 fields.
5131 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
5132 parse the long line.
5134 2005-06-04 Stepan Kasal <kasal@ucw.cz>
5136 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
5137 swallow literals longer than 399. Reported by Ralf Wildenhues.
5138 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
5139 to workaround this limitation.
5141 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
5143 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
5144 to gfortran, and make these the first two compiler names
5145 checked (following the general autoconf preference for gcc).
5147 2005-06-03 Stepan Kasal <kasal@ucw.cz>
5149 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
5150 (DISTCLEANFILES): Remove $(check_SCRIPTS).
5151 (testsuite): Make sure autotest.m4f is up-to-date before using it.
5153 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
5155 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
5156 expression of unbounded size when processing the --list
5157 option. This runs afoul of a limit of 399 bytes per regular
5158 expression on AIX. Problem reported by Ralf Wildenhues.
5160 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
5162 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
5163 * doc/autoconf.texi (Particular Headers): Reword example
5164 for multiline stdbool replacement.
5165 (Setting Output Variables): Reword text a bit. Don't
5166 give all the details about |#_!!_#|.
5167 Reword description of line replacement.
5169 2005-05-31 Dan Manthey <dan_manthey@partech.com>
5171 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
5172 now contain newlines, and substituted files must be referenced on
5173 a line alone; the sed scripts to substitute them are now very
5174 different.
5175 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
5176 commands can be put in a sed script portably.
5177 * doc/autoconf.texi (Setting Output Variables): Document above
5178 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
5179 use of multiline substitution.
5180 * tests/torture.at: No longer expect substitution of newline to fail.
5182 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
5184 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
5185 From Ralf Menzel (trivial change).
5187 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
5189 * tests/local.at: Don't attempt to check for negated character
5190 classes in shell scripts. The test was too brittle.
5192 2005-05-25 Stepan Kasal <kasal@ucw.cz>
5194 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
5195 * doc/autoconf.texi (Limitations of Builtins): Document this
5196 limitation.
5198 2005-05-24 Stepan Kasal <kasal@ucw.cz>
5200 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
5201 common code; used in many places in the tree.
5202 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
5203 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
5205 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
5207 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
5208 messages when ac_unique_file is not found.
5209 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
5210 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
5211 commands, for consistency with AC_MSG_ERROR and such.
5213 * bin/autoconf.as: Make more use of "shift 2" in option processing.
5215 * bin/Makefile.am: Merge the two rules for creating scripts.
5217 2005-05-23 Stepan Kasal <kasal@ucw.cz>
5219 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
5220 obsolete; it was never documented.
5221 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
5223 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5225 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
5226 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
5227 (ac_top_builddir): ... this ...
5228 (ac_top_build_prefix): ... to this; the old name is also kept, for
5229 backward compatibility.
5230 (ac_top_builddir_sub): New variable, without the trailing slash,
5231 always nonempty.
5232 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
5233 * doc/autoconf.texi (Configuration Actions): Rename
5234 ac_top_builddir to ac_top_build_prefix.
5235 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
5236 at_top_builddir to at_top_build_prefix.

5239 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5241 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
5242 of confdefs.h .
5244 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5246 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
5247 argument to m4_foreach. I guess it was necessary in the past,
5248 but I think it's a no-op now.
5250 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5252 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5253 ``cat <<_ACEOF'' commands to one.
5254 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
5255 * lib/autoconf/status.m4: On various places, use expr instead of
5256 ``echo|sed.''
5257 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
5258 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
5259 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
5260 a range.
5261 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
5262 the wrong patterns between ``case'' and ``esac.'' The previous
5263 code had false positives.
5265 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
5267 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
5268 as on 2005-05-02.
5269 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
5270 Mention LIBOBJDIR.

5331 * doc/autoconf.texi (Autoconf Language): Be more precise about
5332 quoting rules. Problems noted by Stepan Kasal.
5333 Also, throughout this document, be more careful about white space.
5334 "blank", "white space", and "space" all have different meanings
5335 and we should be careful to say what we mean.
5337 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
5339 Fix C++ related problems reported by Werner Lemberg.
5340 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

5372 not newline.
5374 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5375 by AC_DEFINE; it was a mistake.
5376 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5378 2005-04-25 Stepan Kasal <kasal@ucw.cz>

5382 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5384 * doc/autoconf.texi (External Software): Quadrigraphs are not

5386 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5387 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5388 comment and reduce m4_default([foo], []) to [foo].
5389 (m4_strip): Update the explanation.
5391 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5393 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5394 Remove core.conftest.* too; it's generated by Tru64 5.1.
5395 Problem reported by Jennis Pruett.
5396 * lib/autoconf/functions.m4
5397 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5398 Don't bother to remove core files; AC_RUN_IFELSE should do that
5399 for you.
5401 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5403 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

5449 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5451 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5453 * NEWS: The configure command now warns you if you attempt to use
5454 a directory whose name contains a special character like space,
5455 newline, or "\".
5456 * doc/autoconf.texi (Installation Directory Variables): Allow
5457 "," in file names. Do not use \@; it's not a portable regexp.

5465 * doc/autoconf.texi (File System Conventions): Warn about
5466 unportable file names.
5467 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5468 (AC_INIT): Use it.
5469 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5470 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5471 ac_pwd, and quote srcdir.
5472 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5474 * doc/autoconf.texi: Fix some systematic formatting problems.
5475 ".)" needs a following @: if not at the end of a sentence, and
5476 similarly for "!)". "etc." should be preceded by a comma.
5477 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5479 2005-03-22 Bruno Haible <bruno@clisp.org>
5481 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5482 argument is often called 'build-aux'.
5484 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5486 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5487 macro AC_TRY_LINK is obsolete.
5488 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5489 `AC_CONFIG_FILES'.
5491 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5493 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5494 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5495 from a Common Lisp's `cl'.
5496 (AC_PROG_CXX): Behave according to the documentation: don't
5497 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5498 make the variable CCC precious; use `cl.exe', not `cl'.
5500 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5501 Alexandre Duret-Lutz <adl@gnu.org>
5503 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5504 /dev/null, as "configure" shouldn't read stdin, and this insulates
5505 us from problems (e.g., when testing for "cl"). Also, do this
5506 redirection before invoking "hostname" or "uname", and keep the
5507 original input stream available via...
5508 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5509 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5510 bother with "</dev/null" since it's now done at the top of
5511 'configure'.
5512 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5513 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

5519 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5521 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5522 newline if neither \c nor -n work, as that would output two
5523 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5525 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5527 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5528 This causes that any required macros inside will get before the if.
5529 * doc/autoconf.texi (autom4te.cache): A typo.
5531 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5533 Undo previous change, except keep the change to
5534 lib/autoconf/programs.m4 that replaced grep with shell
5535 pattern-matching. This is because net-snmp configure reads stdin.
5536 Reported by Noah Misch.
5538 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5540 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5541 from /dev/null, as "configure" shouldn't read stdin, and this
5542 insulates us from problems (e.g., when testing for "cl").
5543 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5544 before invoking "hostname" or "uname".
5545 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5546 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5547 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5548 "</dev/null" since it's now done at the top of 'configure'.
5549 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5550 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5551 Also, replace grep with shell pattern-matching, to save a process.
5553 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5555 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5556 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5557 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5558 compiler.
5560 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5562 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5563 grep -q isn't portable. Improve grep -s explanation.
5564 Problem reported by Dan Manthey.
5566 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5568 * doc/autoconf.texi (Special Shell Variables): Clarify
5569 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5571 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5573 * doc/autoconf.texi: Use @acronym for DJGPP.
5574 Fix some @code's that should have been @env's, and vice versa.
5575 Sort environment variable names.
5576 Mention that shells no longer inherit IFS.
5577 Don't recommend PATH_SEPARATOR=';' so strongly.
5578 Mention that $RANDOM might expand to the empty string.
5579 "symlink" and "soft link" -> "symbolic link".
5580 Improve mktemp description (reported by Bruno Haible).
5582 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5584 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5585 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5586 Likewise.
5587 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):

5590 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5592 * NEWS: Mention AT_COPYRIGHT.
5594 * tests/local.at (AT_CMP): Use diff directly on input files rather
5595 than copying them.
5597 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5598 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5600 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5601 and Paul Eggert <eggert@cs.ucla.edu>

5610 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5611 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5612 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5613 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5614 (Standard regular expressions): New test.
5615 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5616 excess test name quoting.
5617 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5618 CPPFLAGS to `configure' instead of setting it in `configure'.
5620 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5621 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5622 on some platforms.
5624 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5625 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
5627 * tests/local.at (AT_CMP): New macro.
5628 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

5632 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
5633 * tests/c.at (Extensions): Do not exit early.

5653 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
5655 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5656 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5658 Try not to generated lines of unlimited length, as POSIX places a
5659 2047-byte limit on line length of portable text files.
5660 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5661 Use newline as a separator, not space.
5662 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
5663 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
5664 space.
5666 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5668 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
5669 as_func_*. Add test to check whether positional parameters
5670 are restored after function return.
5672 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
5674 * doc/autoconf.texi (Special Shell Variables): Mention _,
5675 BIN_SH, DUALCASE. Say that variables other than "status" are safe
5676 if they contain a lower-case letter. The DUALCASE problem was
5677 reported by Ralf Wildenhues.
5679 * bin/autoconf.as: Don't exit with status 0 after write failure
5680 with --help or --version.
5681 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

5687 Unicos 9 sed limitations.
5688 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
5689 to get the option-enhanced interface on older Crays. Try ftn for
5690 Fortran 95 (newer Crays).
5692 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
5694 * man/Makefile.am (.x.1): Go back to the simple solution, but take
5695 care to echo the commands, so the user knows what's going on.
5696 Modified from a suggestion by Stepan Kasal.
5698 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

5706 Based on a proposed patch by Ralf Wildenhues.
5708 * man/Makefile.am (.x.1): Make sure the required generated files
5709 are up to date. Problem and original solution proposed by Stepan Kasal.
5710 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
5711 implicit-man-prerequisites): New rules, used by the above.

5717 2005-01-29 Stepan Kasal <kasal@ucw.cz>
5719 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5720 Update the long comment explaining it.
5722 m4_require no longer writes an ``is required by'' line to the
5723 execution stack. It contains only one bit of non-redundant
5724 information: that the macro was required, not called. And even
5725 this bit is useless in most situations: have you ever met a macro
5726 which both calls and requires the same macro?
5728 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5729 (_m4_defun_pro_outer): ... only via this macro, for the outermost
5730 macro.
5731 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
5732 (m4_expansion_stack_pop): Remove the misplaced comment.
5733 (m4_require): Don't put the ``is required by'' line to the
5734 execution stack; slightly improve the out-of-a-defun error message.
5735 (_m4_divert_grow): New macro, counter for the temporary diversions.
5736 (_m4_require_call): Use it.
5737 * tests/m4sugar.at (m4_require): Expect output without the
5738 ``is required by'' messages.
5740 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5742 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5743 rather than x for expr.
5745 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5746 this is safe.
5747 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
5748 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

5758 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
5759 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
5760 from masters, so that FileUtils.pm's update_file provide --force
5761 support.
5762 * bin/autoheader.in: Pass $force to update_file so that
5763 config.h.in is always recreated when --force.
5765 2005-01-24 Stepan Kasal <kasal@ucw.cz>
5767 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
5769 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
5771 * doc/autoconf.texi (Limitations of Builtins): Clarify that
5772 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
5774 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5776 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5777 Warn about newline stripping in `` and $(). Update Solaris
5778 version to 9.
5779 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5780 X insulates us from future changes to Posix.
5781 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
5782 stripping.
5784 2005-01-19 Stepan Kasal <kasal@ucw.cz>
5786 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

5789 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
5791 * doc/autoconf.texi (Limitations of Usual Tools): Document bug

5802 ulongval to be static, to avoid unwanted GCC warning. Problem
5803 reported by Michael Jennings via Daniel Reed; see
5804 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
5806 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5808 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5810 datadir, infodir, and mandir. Adjust argument parsing code.
5811 (_AC_INIT_HELP): Update help text.

5813 new variables.
5815 2005-01-04 Noah Misch <noah@cs.caltech.edu>
5817 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
5818 not seem to work, assume it does set $(MAKE).
5819 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
5821 2005-01-03 Stepan Kasal <kasal@ucw.cz>
5823 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

5829 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
5830 (_m4_divert_n_stack): New macro; the expansion is
5831 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
5832 otherwise.
5833 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5834 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5835 stored in _m4_divert_diversion or _m4_divert_dump.
5836 (m4_divert_pop): When the parameter is given, compare the symbolic
5837 name with the last diversion pushed on the stack. Previously, the
5838 current diversion was compared with the numeric value of the
5839 diversion given as the parameter.
5840 (m4_require): If the macro hasn't been expanded yet, call ...
5841 (_m4_require_call): this new macro.
5843 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5845 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

5874 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
5875 signals that the package uses Automake; a `Makefile.am' is typical but
5876 not essential. Reported by Magnus Therning.
5877 * tests/torture.at (autoreconf.): New banner.
5878 (autoreconf and non-AC configure): Rename to `Non-Autoconf
5879 AC_CONFIG_SUBDIRS'.

6148 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

6267 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
6268 "/usr/include", clear ac_x_includes instead of leaving it as "no"

6363 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6364 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6365 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
6367 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6369 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
6370 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
6371 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
6372 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
6373 * lib/autom4te.in (Automake-preselections): Preselect
6374 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6376 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6378 * lib/autom4te.in (Automake-preselections): Preselect
6379 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6380 trace them.
6382 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6384 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6385 Tru64.
6386 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6387 Document problem with "`""`" in pdksh POSIX mode.
6389 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6391 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6392 with pdksh, too. Problem reported by Patrick Welche via
6393 Gary V. Vaughan.
6394 * doc/autoconf.texi (Shellology): Note that set -o posix is
6395 useful for pkdsh, too.
6397 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6399 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6400 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6401 Don't fail if ENV or BASH_ENV is readonly.
6402 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6403 etc. are read only. Problem reported by Ludovic Courtes.
6405 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6407 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6408 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6409 (trivial change)
6411 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6413 * doc/autoconf.texi (File System Conventions): Warn about
6414 names like "aux". Problem reported by Eric Blake.
6416 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6417 by zero instead of array size, so that we can use any arithmetic
6418 constant expression (instead of requiring an integer constant
6419 expression). This allows us to test expressions like DBL_MAX <
6420 LDBL_MAX, which didn't conform to the C standard using the old
6421 method.
6422 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6423 now that we can do floating-point tests at compile time.
6425 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6427 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6428 and LDBL_EPSILON, as the resulting expression isn't an
6429 integer constant expression and violates the C standard.
6430 Problem reported by Nelson H. F. Beebe. Also, check
6431 for "L" suffix, and check that long double doesn't have
6432 worse range or precision than double, that mixed-mode
6433 arithmetic doesn't generate a diagnostic, that double
6434 constants fit in long double.
6436 2004-06-03 Kevin Ryde <user42@zip.com.au>
6438 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6439 malloc(0) and realloc(NULL,size).
6441 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6442 Bob Proulx.
6444 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6446 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6447 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6448 by Jim Meyering.
6450 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6452 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6453 can be rewritten using if-then-else. Suggested by Bruno Haible.
6455 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6457 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6458 Problem reported by Stepan Kasal.
6460 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6462 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6463 change). Patch reported by Ralf Wildenhues in
6464 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6466 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6467 function F exists if the compiler and linker let you compile an
6468 expression like (F != 0). Recent versions of GCC optimize away
6469 the reference to F in that case, since every function address must
6470 be nonzero, so the link succeeds even if F does not exist.
6471 Problem reported by Manu in
6472 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6474 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6475 "Unix". Many uses changed.
6476 (Limitations of Builtins): Explain better why the ! command isn't
6477 portable.
6479 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6481 * lib/autom4te.in (Automake-preselections): Preselect
6482 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6484 2004-05-19 Kevin Ryde <user42@zip.com.au>
6486 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6487 referencing AC_FUNC_STRERROR_R.
6489 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6490 note pessimistic assumption when cross compiling.
6492 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6494 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6495 (until 2004) invoked subcommands with sh -e, contra POSIX.
6496 Reported by Kevin Ryde.
6498 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6500 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6501 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6502 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6503 `test -f " /usr/bin/grep"', which _always_ failed.
6504 (AC_PROG_SED): Ditto bogus PATH fix.
6505 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6506 requires that grep correctly supports _multiple_ `-e' options, rather
6507 than stating only that grep should accept `-e'.
6509 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6511 Port to C99, which requires that 'exit' be declared.
6513 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6514 to ensure that stdlib.h is included.
6515 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6516 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6517 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6518 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6519 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6520 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6521 when using 'exit' in a test; C99 requires that 'exit' be declared.
6523 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6525 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6526 now prefers 'grep' implementations that accept -e.
6527 (Limitations of Usual Tools): Describe problems of traditional
6528 egrep and fgrep with long input lines, and of traditional grep
6529 with -e.
6530 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6531 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6532 All callers changed. Append /usr/xpg4/bin to the PATH, for
6533 Solaris.
6534 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6535 the user with complaints about multiple -e options.
6536 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6537 Define it with AC_PROG_GREP.
6538 * configure.ac (AC_PROG_GREP): Add.
6539 * lib/freeze.mk (GREP): New macro.
6541 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6543 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6544 a possible candidate only after all others fail, rather than
6545 consulting it first. This improves backward compatibility by
6546 better reflecting the way shell selection occurred in previous
6547 versions of Autoconf, and should help to avoid triggering latent
6548 problems in other packages, such as the one in Automake where zsh
6549 is not handled robustly:
6550 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6551 Although it is not Autoconf's responsibility to work around
6552 problems in Automake, it nevertheless makes sense to avoid
6553 introducing unnecessary incompatibilites.
6555 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6556 Gary V. Vaughan <gary@gnu.org>
6558 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6559 how deeply nested we are when a suitable tool is found, set the
6560 ac_path_TOOL_found flag.
6561 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6562 nested we are in this macro. Break out of all 3 nested loops if
6563 ac_path_TOOL_found is set.
6565 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6567 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6568 of the _AS_PATH_WALK loop too if GNU flavor is found.
6570 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6572 * doc/autoconf.texi (Limitations of Make): Update documentation
6573 for `$<'. New entry `Long lines', based on a report from Simon
6574 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6575 paragraph about DJGPP, based on a mail from Richard Dawe.
6577 2004-04-20 Paul Eggert <eggert@twinsun.com>
6579 * tests/c.at (C keywords): Don't assume that GCC supports
6580 "restrict" and "inline", as sufficiently-old GCC versions do not
6581 (also, GCC configured to be in pedantic C89 mode does not).
6582 Problem reported by Sumit Pandya in:
6583 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6585 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6586 consider -g to work if it generates warnings when plain compiles
6587 don't. Problem reported by Braden McDaniel in:
6588 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6590 * doc/autoconf.texi (Slashes): New section, to document a problem
6591 reported by Jim Meyering in:
6592 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6594 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6595 linker output files before linking, to work around IRIX 6 linker bug.
6596 Problem reported by Rainer Orth in:
6597 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6599 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6601 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6602 best tool so far counter rely on the tool path variable name to
6603 avoid checks for one tool being affected by the results of running
6604 the length check on a previous tool.
6606 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6607 match expression argument, as different greps have different
6608 regular expression flavours.
6609 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6610 literals.
6611 (AC_PROG_EGREP): Pass 'EGREP$'.
6612 (AC_PROG_GREP): Pass 'GREP$'.
6614 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6616 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6617 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6619 2004-03-29 Paul Eggert <eggert@twinsun.com>
6621 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6622 Types, Specific Compiler Characteristics, System Services,
6623 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6624 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6625 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6626 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6627 Likewise.
6628 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
6629 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
6630 AC_TYPE_OFF_T): Likewise.
6631 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
6632 Likewise.
6634 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
6635 pacify libtool 1.5.2. Fix quoting problems in sed command.
6637 2004-03-28 Paul Eggert <eggert@twinsun.com>
6639 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6640 now defines HAVE_DECL_TZNAME if it is declared, when
6641 HAVE_STRUCT_TM_TM_ZONE is not defined.
6642 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6643 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6644 for HAVE_TZNAME.
6646 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
6648 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
6649 superfluous backslashing of quotes (") in sed expressions;
6650 thanks to Paul Eggert.
6652 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6654 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6655 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6656 H. F. Beebe for the bug report.
6658 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6660 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6661 quoted -cmdline argument in Portland Group compiler (bug
6662 reported by Jeffrey J. Barteet).
6664 2004-03-25 Kevin Ryde <user42@zip.com.au>
6666 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
6667 (Run Time): ... here, where it's now mentioned.
6669 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
6671 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
6672 inherits from language Autoconf-without-aclocal-m4.
6673 (Customizing autom4te): Adjust example; the cache must now be
6674 disabled for language Autoconf-without-aclocal-m4.
6676 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
6677 Nathanael Nerode <neroden@twcny.rr.com>

6687 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
6688 AC_CHECK_TOOLS.
6689 (Specifying Names): Document the reason for these future
6690 behavioral changes.
6691 * tests/mktests.sh: Do not generate tests for the
6692 new macros.
6693 * NEWS: Document these changes.
6695 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6696 they make TeX hang up.
6698 2004-03-15 Paul Eggert <eggert@bogus.example.com>
6700 * NEWS: New macro AC_CHECK_ALIGNOF.
6701 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6702 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6703 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6704 vowel.
6705 (AC_CHECK_ALIGNOF): New macro.
6706 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
6707 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
6708 those for sizeof.
6710 2004-03-03 Paul Eggert <eggert@twinsun.com>
6712 * bin/Makefile.am (edit): Don't use $< in a context where
6713 POSIX doesn't require support for it. Use $@.in instead.
6714 Problem reported by Anthony N. Frasso in
6715 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6716 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
6718 2004-02-23 Gary V. Vaughan <gary@gnu.org>
6720 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
6721 from the next generation of Libtool.
6722 * lib/autom4te.in (Autoreconf-preselections): Ditto.
6724 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6726 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

6729 2004-02-18 Paul Eggert <eggert@twinsun.com>
6731 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6732 problem on QNX reported by Stephen Rasku in
6733 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6735 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6736 $(m4sh_m4f_dependencies); this removes a FIXME.
6737 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6738 (MAINTAINERCLEANFILES): Split into pieces,
6739 one per related section. Add $(srcdir)/wrapper.in.
6741 2004-02-09 Paul Eggert <eggert@twinsun.com>
6743 * doc/autoconf.texi (Setting Output Variables): Emphasize that
6744 AC_SUBST provides no portable way to escape literal newlines.
6746 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6747 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6748 Darwin uses -lcrt2.o and there's little point to cataloging all
6749 the system variants. Partial fix reported by Andreas Waechter in:
6750 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
6751 for bug reported by Nelson H. F. Beebe in:

6759 acobsolete.m4, suggested by Alexandre Duret-Lutz.
6761 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
6763 * bin/autoupdate.in: Define __file__ so that warnings
6764 refer to the correct file.
6765 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
6766 the behavior of the third argument.
6767 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6768 correctly the behavior of the third argument. Document
6769 what the three macros that AU_DEFUN defines do. Fix
6770 warning message when the third argument includes $0
6771 (reported by Alexandre Duret-Lutz).
6773 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6774 Eric Sunshine <sunshine@sunshineco.com>
6775 Paul Eggert <eggert@twinsun.com>
6777 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
6778 (AS_INIT): Output shell initialization there. Removed optional
6779 parameter. Expand _AS_SHELL_FN_SPY.
6780 (AS_INIT_WITH_SHELL_FN): Removed.
6781 (_AS_SHELL_FN_SPY): New macro.
6782 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
6783 macros.
6784 (AS_SHELL_SANITIZE): Remove loop to find better shell
6785 and documentation for the parameter.
6786 (_AS_DETECT_BETTER_SHELL): Move it here.
6787 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
6788 (_AS_RUN): Move it here, support testing with eval.
6789 (AS_REQUIRE_SHELL_FN): Require shell functions when
6790 it is used.
6791 (_AS_LINENO_WORKS): Put around braces, we do not
6792 trigger the bash bug anymore.
6793 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
6794 use AS_INIT_WITH_SHELL_FN.
6795 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6797 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6799 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
6800 * doc/autoconf.texi: Don't say that the third parameter
6801 is broken.
6802 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
6803 (AU_DEFUN): Honor the third parameter, create autoupdate
6804 macros with AU_DEFINE.
6805 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,

6814 * lib/autoconf/status.m4: Remove FIXME.

6825 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

6827 the 2003-05-22 change, which removed the older years from the list.
6828 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6830 2004-01-27 Gary V. Vaughan <gary@gnu.org>

6835 possible.
6836 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
6837 AC_PROG_GREP.
6838 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
6839 egrep and fgrep respectively if $GREP -E/-F don't work.
6840 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6841 _AC_PROG_GREP, and AC_PROG_SED.
6842 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6843 longest input length accepted by a command.
6844 (AC_PROG_SED): Use it.
6845 * doc/autoconf.texi (Particular Programs): Document the changes.
6846 * NEWS: Updated.
6848 2004-01-27 Paul Eggert <eggert@twinsun.com>
6850 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

6852 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
6853 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
6855 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6856 bin/autoconf.in, config/Makefile.in, config/config.guess,
6857 config/config.sub, config/install-sh, config/mdate-sh,

6872 2004-01-26 Paul Eggert <eggert@twinsun.com>
6874 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6875 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6876 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6877 not <inttypes.h>. Problem reported by Tim Mooney in
6878 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6879 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6880 Likewise.
6882 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6883 otherwise "make check" fails because it forbids cmp (I guess
6884 because cmp treats files as binary on DOS-like systems).
6886 * tests/mktests.sh: Update copyright date to 2004, since some tests
6887 have changed in 2004.
6889 2004-01-23 Gary V. Vaughan <gary@gnu.org>

6892 non-truncating sed or gsed program in PATH.
6893 * tests/acprograms.at: Add it.

6895 * NEWS: Updated.
6897 2004-01-15 Paul Eggert <eggert@twinsun.com>
6899 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6900 -std1 disables some useful extensions on Tru64. Problem reported
6901 by N. Lichtmaier in
6902 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6904 2004-01-14 Paul Eggert <eggert@twinsun.com>
6906 * doc/autoconf.texi (Programming in M4sh): Document that
6907 AS_MKDIR_P succeeds if the destination is a symbolic link
6908 to an existing directory.
6909 (Limitations of Usual Tools): Note that mkdir -p might not
6910 succeed on symlinks to directories.
6912 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6914 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6915 * bin/autoheader.in: Grammar fix in message.
6916 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6917 Test for dir before calling mkdir -p. (trivial changes)
6919 2004-01-13 Eric Blake <ebb9@byu.net>
6921 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6922 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6924 2004-01-10 Jim Meyering <jim@meyering.net>
6926 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6928 2004-01-09 Paul Eggert <eggert@twinsun.com>
6930 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6931 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6932 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6933 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6934 AC_COMPILE_IFELSE, since we now assume our caller invokes
6935 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6936 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6937 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6938 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6940 2004-01-07 Paul Eggert <eggert@twinsun.com>
6942 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6943 `"'...'"`, as it's confusing (and I suspect it may not work on
6944 some platforms). The code was incorrect anyway, as it assumed
6945 that \$ evaluated to itself in that context. Reported by
6946 Alexandre Duret-Lutz.
6948 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6950 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6951 and _LT_AC_TAGCONFIG.

6955 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6956 example, and add more examples. Reported by Eric Sunshine.
6958 2004-01-05 Paul Eggert <eggert@twinsun.com>
6960 * doc/autoconf.texi (Limitations of Usual Tools):
6961 Remove warning against "rm -fr" introduced yesterday; it
6962 was a false alarm.
6964 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6965 autoscan, autoupdate, ifnames): Don't use chmod -w.
6966 * lib/Makefile.am (autom4te.cfg): Likewise.
6967 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6968 "chmod -w".

6971 Paolo Bonzini <bonzini@gnu.org>
6973 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6974 by doing lineno substitution only on lines containing "$LINENO".
6976 2004-01-04 Paul Eggert <eggert@twinsun.com>
6978 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6979 Use "rm -f" to remove conftest.sed, not plain "rm".
6980 Bug reported by David Relson in
6981 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6983 * Makefile.am (autom4te-update):
6984 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6985 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6986 * doc/autoconf.texi (Guidelines): Likewise.
6987 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

6992 * tests/Makefile.am (clean-local): Likewise.
6993 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6994 srcdir): Likewise.
6995 * doc/autoconf.texi (Limitations of Usual Tools):
6996 Warn against "rm -fr".
6998 2004-01-03 Paul Eggert <eggert@twinsun.com>
7000 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
7001 -c -o might not work. From a suggestion by Kevin Ryde.
7002 (C Compiler, Generating Sources, Limitations
7003 of Usual Tools, Limitations of Make, Making testsuite Scripts):
7004 Don't put '-o' after non-options, as POSIX doesn't allow this.
7005 Mention that cc's name might be gcc or c89 or whatever.
7007 2004-01-04 Kevin Ryde <user42@zip.com.au>
7009 * doc/autoconf.texi: Add various further index entries.
7011 2003-12-29 Paul Eggert <eggert@twinsun.com>
7013 * bin/autoreconf.in (autoreconf_current_directory):
7014 Fix typo: mkdir without umask arg.
7016 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
7018 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
7019 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
7020 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
7021 explanation clearer.
7023 2003-12-24 Andreas Schwab <schwab@suse.de>
7025 * doc/autoconf.texi (Default Includes): Fix misspelling of
7026 AC_INCLUDES_DEFAULT.

7030 * configure.ac: Test if sh -n works.
7031 * configure: Regenerate.
7032 * tests/atlocal.in: Store the result here.
7033 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
7034 tools.at, looking in atlocal's ac_cv_sh_n_works instead
7035 of explicitly testing.
7036 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
7037 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
7038 * tests/tools.at (Syntax of the shell scripts): Simplify
7039 using AT_CHECK_SHELL_SYNTAX.

7053 Extracted from AS_SHELL_SANITIZE.
7054 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
7055 macros.
7056 (AS_SHELL_SANITIZE): Move reinvocation code from
7057 _AS_LINENO_WORKS, use it to find out if shell
7058 functions work.
7059 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
7060 does not work.
7061 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
7062 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

7080 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

7108 parameter of AU_DEFUN.

7123 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
7124 than $target since the latter is not usual, add guidelines on when to

7206 2003-10-28 Akim Demaille <akim@epita.fr>
7208 * Makefile.cfg (local_updates, executable-update): Tweak to be

7265 _AC_COMPILER_EXEEXT to attempt a link. If linking fails,
7266 override AC_LINK_IFELSE.
7268 2003-10-15 Paul Eggert <eggert@twinsun.com>
7270 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug in
7271 pdksh 5.2.14. Bug reported by Ralf Corsepius.
7272 * doc/autoconf.texi (Shellology): Mention the Korn shell and pdksh.
7273 Mention /usr/dt/bin/dtksh on Solaris.
7274 (Shell Substitutions): Warn about $((...)).
7275 (Parentheses): New section.
7277 2003-10-15 Kevin Ryde <user42@zip.com.au>
7279 * doc/autoconf.texi (Function Portability): Add @prindex for exit.
7280 Add putenv and unsetenv. Add sysconf _SC_PAGE_SIZE.
7282 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
7284 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
7285 cross test.
7287 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
7289 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
7290 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
7292 2003-10-10 Andreas Schwab <schwab@suse.de>
7294 * bin/autoheader.in: Avoid empty first line in --version and
7295 --help output.
7296 * bin/ifnames.in: Likewise.
7298 2003-10-09 Paul Eggert <eggert@twinsun.com>
7300 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
7301 Issue a more-informative diagnostic.
7302 Problems reported by Eric Sunshine.
7304 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7306 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7307 -mGLOB_options_string stuff for Intel ifc, which can cause
7308 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
7309 pattern-matching instead of grep.
7311 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7313 * doc/autoconf.texi: Document new FC Fortran macros.
7315 2003-10-08 Gary V. Vaughan <gary@gnu.org>
7317 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
7318 that future autopoint/aclocal/automake/autoreconf will be able
7319 to trace to find where to install local m4 macros.
7320 * doc/autoconf.texi (Input): Document it.
7321 * NEWS: Updated.
7323 2003-10-06 Gary V. Vaughan <gary@gnu.org>
7325 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
7326 -lcrtbegin.o to list of ignored flags and fix underquoting of
7327 -lcrt[01].o.
7329 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
7331 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7332 cache variable instead of $G77 to decide whether to include -O2,
7333 since $G77 is specific to Fortran 77.
7335 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7337 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
7338 free" flag. Re-order flags tested into rough order of popularity.
7340 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7342 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7343 arguments so that it can be used with syntax identical to
7344 AC_PROG_F77, and so that we can more easily decide to
7345 remove/deprecate the DIALECT optional argument in the future if it
7346 proves troublesome.
7347 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7348 non-freeform-supporting compilers. Document freeform flags.
7350 2003-10-03 Akim Demaille <akim@epita.fr>
7352 * configure.ac: Look for emacs, not macs.
7353 Reported by Eric Sunshine.
7355 2003-10-03 Akim Demaille <akim@epita.fr>
7357 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
7358 * bin/autoreconf.in (autoreconf_current_directory): Create the
7359 AUX_DIR if needed, for sake of automake --add-missing etc.
7360 Suggested by Alexandre Duret-Lutz.
7362 2003-10-03 Akim Demaille <akim@epita.fr>
7364 * configure.ac: Quotation and formatting changes.
7365 (EMACS): Don't set it if it is not recent enough to support
7366 autoconf-mode.el.
7367 From Eric Sunshine.
7369 2003-10-02 Akim Demaille <akim@epita.fr>
7371 * bin/ifnames.in (&scan_file): Skip C++ comments.

7381 Version 2.57f.
7383 2003-09-30 Paul Eggert <eggert@twinsun.com>
7385 * lib/Autom4te/XFile.pm: Use Errno.
7386 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
7387 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
7389 2003-09-30 Akim Demaille <akim@epita.fr>
7391 * config/announce-gen (&print_news_deltas): Extracted from...
7392 (&print_changelog_deltas): here.
7393 (&news_file): Rename as...
7394 (@news_file): this.
7396 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
7398 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
7399 have been created when invoking the compiler.
7400 * tests/fortran.at (GNU Fortran 77): Quote $G77.
7402 2003-09-29 Akim Demaille <akim@epita.fr>
7404 Version 2.57e.
7406 * config/mkinstalldirs: Upgrade.
7408 2003-09-28 Paul Eggert <eggert@twinsun.com>
7410 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
7411 Problem reported by Lars J. Aas in
7412 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
7413 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7414 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7415 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7417 2003-09-26 Akim Demaille <akim@epita.fr>
7419 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7420 directory for AC_CONFIG_COMMANDS' first argument exists.
7421 This makes valid the invocation of _AC_SRCPATH that follows.
7422 Reported by Eric Sunshine.
7423 * doc/autoconf.texi (Configuration Commands): Adjust.
7425 2003-09-26 Akim Demaille <akim@epita.fr>
7427 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7428 Reported by Ralf Corsepius.
7430 2003-09-26 Akim Demaille <akim@epita.fr>
7432 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
7433 arguments.
7434 Actually, use AU_ALIAS.
7435 From Bruno Haible.
7437 2003-09-26 Paul Eggert <eggert@twinsun.com>
7439 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
7440 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
7441 Problem reported by Eric Sunshine in:
7442 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
7444 2003-09-26 Akim Demaille <akim@epita.fr>
7446 The test suite are sometimes assigning timings incorrectly.
7447 Reported by Henk Krus.
7448 Diagnosed by Nicolas Joly.
7450 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7451 AT_help_all.
7452 Instead of making AT_help a sequence of assignments to grow
7453 $at_help_all, just make AT_help_all be the growing contents of
7454 $at_help_all, and make a single assignment in...
7455 (AT_INIT): here.
7456 (at_times_skip): Flip the meaning and rename as...
7457 (at_times_p): this.
7458 (AT_INIT): When summarizing the test that ran, remove
7459 $at_times_file after use, and check it is present before trying to
7460 use it.
7462 2003-09-25 Akim Demaille <akim@epita.fr>
7464 Version 2.57d.
7466 * bin/Makefile.am (edit): Handle '@configure_input@'.
7467 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
7468 (ifnames): chmod -w.
7469 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7470 executables, not bin/ executables! Otherwise all the magic needed
7471 to find non installed files is turned off. This caused a failure
7472 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7473 as found in its environment (sent by tests/autoreconf): pointing
7474 to bin/autom4te that could not find its files.
7475 * tests/mktests.sh: Force the replacement of generated files, for
7476 the sake of "mv" program that are interactive when overwriting a
7477 -w file.
7478 * config/install-sh: Upgrade from CVS Automake.
7480 2003-09-23 Paul Eggert <eggert@twinsun.com>
7482 * doc/autoconf.texi (Limitations of Builtins): Document test -h
7483 versus test -L issues.
7485 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
7486 Paul Eggert <eggert@twinsun.com>
7488 Trivial change to support GCC's configuration procedure.
7489 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
7490 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
7491 about inconsistency if the preprocessor is set to give errors for
7492 any warning.
7493 * doc/autoconf.texi (C Compiler Characteristics): Document this.
7495 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
7497 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
7498 and XFile.pm from Automake.
7499 * lib/Autom4te/XFile.pm: Update from Automake.
7501 2003-09-12 Akim Demaille <akim@epita.fr>
7503 Version 2.57c.
7505 2003-09-12 Akim Demaille <akim@epita.fr>
7507 * config/config.guess, config/config.sub, config/missing,
7508 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
7509 from masters.
7511 2003-09-12 Akim Demaille <akim@epita.fr>
7513 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
7514 not asm/types.h.
7516 2003-09-11 Akim Demaille <akim@epita.fr>
7518 * doc/autoconf.texi (Header Portability): linux/random.h.
7519 From Peter Hendrickson.
7521 2003-09-10 Akim Demaille <akim@epita.fr>
7523 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
7524 willing to edit the output files.
7526 2003-09-10 Akim Demaille <akim@epita.fr>
7528 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
7529 and AC_FC_FREEFORM.
7530 * tests/mktests.sh: Skip AC_FC_SRCEXT.
7531 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
7533 2003-09-09 Akim Demaille <akim@epita.fr>
7535 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
7536 Reported by Gary Vaughan.
7537 * bin/autom4te.in (handle_m4): Likewise.
7539 2003-09-09 Akim Demaille <akim@epita.fr>
7541 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
7542 trailing files.
7544 2003-09-07 Paul Eggert <eggert@twinsun.com>
7546 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
7547 Improve the accuracy of the wording about obsolescence.
7548 From a suggestion by Ian Lance Taylor in
7549 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
7551 2003-09-05 Paul Eggert <eggert@twinsun.com>
7553 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
7554 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
7556 2003-09-04 Akim Demaille <akim@epita.fr>
7558 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
7559 AC_FUNC_WAIT3.
7561 2003-09-04 Akim Demaille <akim@epita.fr>
7563 * bin/autom4te.in: Use &fatal where more appropriate than &error.
7564 (freeze): When exiting, use $exit_code.
7565 * lib/autoconf/fortran.m4: Comment changes.
7567 2003-09-04 Akim Demaille <akim@epita.fr>
7569 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7571 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7573 Add support for newer Fortran dialects. The F77 interface is
7574 unchanged, and continues to support Fortran 77. New FC macros
7575 correspond to all the old F77 macros, with output variables FC,
7576 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7577 available dialect, but older dialects can be specified. There are
7578 new macros AC_FC_SRCEXT to set the source extension, and
7579 AC_FC_FREEFORM to accept free-form source files.
7581 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
7582 New macros.
7583 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
7584 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
7585 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
7586 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

7588 AC_LANG_PREPROC(Fortran), AC_LANG_COMPILER(Fortran),
7589 _AC_FC_DIALECT_YEAR, _AC_F95_FC, _AC_F90_FC, _AC_F77_FC,

7593 AC_FC_DUMMY_MAIN, _AC_FC_MAIN, AC_FC_MAIN, __AC_FC_NAME_MANGLING,
7594 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
7595 AC_FC_SRCEXT, AC_FC_FREEFORM):
7596 New macros.
7597 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
7598 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
7599 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
7600 Rewrite in terms of the above.
7601 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
7602 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
7603 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
7604 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
7606 2003-09-02 Paul Eggert <eggert@twinsun.com>
7608 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
7609 Document problems with timestamp resolution that 'make', 'cp -p', and
7610 'touch -r' have.
7612 2003-08-27 Akim Demaille <akim@epita.fr>
7614 * tests/m4sugar.at (cross_warning): Make sure to enable the
7615 output, so that we can track spurious m4sugar output.
7616 * tests/local.at: Require 2.57.
7617 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7618 are defaulted by AT_CHECK anyway.
7619 Use AT_CHECK_AUTOM4TE.
7620 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7621 missing dnl.
7623 2003-08-27 Akim Demaille <akim@epita.fr>
7625 * bin/autoheader.in: Issue the "Using auxiliary..." message only
7626 when -Wobsolete is set.
7627 Set it on by default.
7628 Suggested by Klee Dienes.
7630 2003-08-27 Akim Demaille <akim@epita.fr>
7632 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
7633 documentation.
7634 From Guido Draheim.
7636 2003-08-26 Akim Demaille <akim@epita.fr>
7638 * doc/autoconf.texi (Output): Make clear that one can run code
7639 after AC_OUTPUT.
7641 2003-08-25 Akim Demaille <akim@epita.fr>
7643 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
7644 CVS Bison.
7646 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
7648 * bin/autoreconf.in (parse_args): Do not pass --no-force to
7649 Automake versions prior to 1.8.

7654 From Ville Karaila.
7656 2003-08-24 Akim Demaille <akim@epita.fr>
7658 * configure.ac: Bump to 2.57c.
7660 2003-08-22 Akim Demaille <akim@epita.fr>
7662 Version 2.57b.
7664 * Makefile.cfg (local-checks-to-skip): New.
7665 * Makefile.maint (local-check): Rename as...
7666 (local-checks-available): this.
7667 (local-check): New.
7669 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
7670 * configure.ac: Require Automake 1.7.6.
7672 2003-08-22 Akim Demaille <akim@epita.fr>
7674 Output stack traces in warnings.
7676 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
7677 Replace the former...
7678 (m4_warn): Pass the call stack to _m4_warn.
7679 * bin/autom4te.in: Adjust to output the call stack.
7680 * tests/m4sugar.at (m4@&t@_warn): Adjust.
7682 2003-08-22 Akim Demaille <akim@epita.fr>
7684 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
7685 * bin/autom4te.in: Adjust.
7687 2003-08-21 Akim Demaille <akim@epita.fr>
7689 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7690 (&verbose): Remove.
7691 (&getopt): Adjust the note and verb channels, depending upon
7692 --verbose.
7693 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
7694 * bin/autoupdate.in: Adjust.
7695 Use &verb, not &verbose.
7697 2003-08-21 Akim Demaille <akim@epita.fr>
7699 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7700 &parse_WARNINGS.
7701 ($help): Use Autom4te::ChannelDefs::usage.
7702 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7703 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7705 2003-08-21 Akim Demaille <akim@epita.fr>
7707 First stab at preserving warnings between calls to autom4te,
7708 including when the cache is used.
7710 There are still several issues: (i) there are too many runs of m4
7711 (one for include, one for warnings, and some more), (ii) warnings
7712 spreading on several lines are not handled gracefully, (iii) the
7713 code meant to have the call stack display for errors does not work
7714 (its handling should move from m4 to autom4te).
7716 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7717 Use them.
7718 (@preselect): Add m4_warn.
7719 ($exit_status): Remove, use $exit_code.
7720 ($help): Use Autom4te::ChannelDefs::usage.
7721 (&handle_m4): No longer define the m4_warnings.
7722 At each run, extract and report the warnings.
7723 Always cache the result, including if the exit status is on
7724 failure, since if nothing changes, we should result in the same
7725 failure, hence we can use the cache.
7726 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7727 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7728 Remove.
7729 (m4_warn): Redefine as a do-nothing: it is its invocation that
7730 matters, as warnings are now reported via traces.
7731 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7732 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7733 the latter reveals calls to the former.
7735 Adjust the tests.
7737 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

7774 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7775 (&xsystem, &contents): Remove, since they are exported by...
7776 * lib/Autom4te/FileUtils.pm: this.
7777 More perldoc.
7778 * lib/Autom4te/General.pm (&up_to_date_p): Move to...

7840 2003-08-13 Derek Price <derek@ximbiot.com>
7842 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

7859 in Bash 2.01. Problem reported by Brian Gough in
7860 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7862 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>

7869 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7870 inside '#ifndef __cplusplus'. Problem reported by
7871 Bob Friesenhahn.
7873 2003-07-06 Bill Clarke <llib@computer.org>
7875 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7876 'long', not 'int', for benefit of Sun's recent C++ compilers
7877 (trivial change). See:
7878 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7879 (This really should be 'intptr_t', not 'long', but that would
7880 take more work.)
7882 2003-06-25 Akim Demaille <akim@epita.fr>
7884 * lib/Makefile.am (autom4te.cfg): Make it read only.
7885 Depend on Makefile since it contains substitutions.
7886 From Paolo Bonzini.

7894 From Gareth McCaughan.
7896 2003-06-23 Akim Demaille <akim@epita.fr>
7898 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7899 not all of them. This fixes 1. the fact that when testing
7900 Autoconf there are many many config.log, 2. the incorrect use of
7901 top_srcdir to find config.log.
7902 Don't mix the detailed output of failed test with the summary of
7903 failures. Rather, append detailed log afterwards.
7905 2003-06-23 Akim Demaille <akim@epita.fr>
7907 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7908 always run: output config.log on $at_group_log.
7910 2003-06-23 Akim Demaille <akim@epita.fr>
7912 * tests/torture.at (#define header templates): Don't use quotes in

7917 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.

7926 2003-06-21 Kevin Ryde <user42@zip.com.au>
7928 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7929 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7930 ensuring we add -std1 for full-ANSI.
7932 * doc/autoconf.texi (hdrindex): New macro.

7935 2003-06-20 Akim Demaille <akim@epita.fr>

7939 2003-06-20 Akim Demaille <akim@epita.fr>
7941 Version 2.57a.
7943 2003-06-20 Akim Demaille <akim@epita.fr>
7945 * bin/autom4te.in: Don't rely on $HOME being defined.
7946 Reported by Marc Espie as PR/233.
7948 2003-06-20 Akim Demaille <akim@epita.fr>
7950 * lib/autotest/general.m4: Use at_times_file only if used.
7951 From Nicolas Joly.

7959 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7961 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7962 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7963 (TEST_SCRIPT): New diversion.
7964 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7965 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7966 (AT_INIT): Support for expected failures.
7968 2003-06-02 Akim Demaille <akim@epita.fr>
7970 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7971 changes.
7972 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7973 Autoconf nor Automake.
7974 (&contents): New, from Automake.
7975 PODify.
7977 2003-05-28 Paul Eggert <eggert@twinsun.com>
7979 * NEWS, doc/autoconf.texi (Particular Functions),
7980 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7981 is the inverse of localtime.
7983 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7985 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7986 (handle_exec_errors): New function. Work around $! being
7987 altered by WEXITSTATUS.
7988 (xqx, xsystem): Use handle_exec_errors.
7990 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7992 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7993 Do not call `_exit()', simply modify `$?'.
7994 (xsystem): Reset $! before running system, and check it afterward.
7995 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7996 63 for version mismatches.
7998 2003-05-23 Akim Demaille <akim@epita.fr>
8000 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
8001 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8002 the middle of a line).
8003 * lib/m4sugar/m4sugar.m4: Likewise.
8004 Remove useless spaces in comments.
8006 2003-05-23 Akim Demaille <akim@epita.fr>
8008 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8009 exit 63, so that we (or Automake's "missing") can tell the
8010 difference with a plain failure.
8011 * doc/autoconf.texi (Notices): Adjust.
8013 2003-05-23 Akim Demaille <akim@epita.fr>
8015 * Makefile.am, bin/Makefile.am, config/Makefile.am,
8016 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
8017 White spaces cleanup.
8019 2003-05-22 Jim Meyering <jim@meyering.net>
8020 Paul Eggert <eggert@twinsun.com>
8022 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8023 Remove `#include <stdlib.h>' from the list; we should never
8024 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8025 resulting namespace pollution would cause other tests to fail.
8026 Configure scripts run with some older versions of g++ and HP's
8027 aCC would fail due to such an #include. Problems reported by
8028 Matthew Mueller in <http://bugs.debian.org/120704> and by
8029 Keith Bostic in
8030 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
8031 In the test, use the test declaration before including <stdlib.h>,
8032 as that's closer to how it'll be used.
8034 2003-05-23 Akim Demaille <akim@epita.fr>
8036 * doc/autoconf.texi (Header Portability): ucred.h.
8037 From Ian Redfern.
8039 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8041 Overhaul Autotest's logging: generate separate log files
8042 in testsuite.dir/NNN/testsuite.log, and append them to
8043 testsuite.log instead of re-running the test verbosely.
8045 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
8046 file descriptor, write 0 to at_status_file instead of setting
8047 at_status=0, initialize some new variables (at_status_file,
8048 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
8049 to rerun the tests, instead append the at_group_log to the
8050 at_suite_log when a test fails.
8051 (AT_SETUP): pipe the test case's output into at_tee_pipe,
8052 with the AS_MESSAGE_LOG_FD redirected to stdout.
8053 (AT_CLEANUP): save the output status in $at_status_file
8054 and restore it, redirect the AS_MESSAGE_LOG_FD back to
8055 its original place.
8056 (AT_CHECK): since tests are run with a redirected stdout,
8057 and used to be re-run in verbose mode, turn some $at_verbose
8058 into echo, and don't redirect the output of testing stdout
8059 and stderr.
8061 * lib/autotest/autoconf.texi (testsuite Scripts): Update
8062 the name of the debugging directory and information about
8063 its contents.
8065 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8067 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
8068 parameter.
8070 2003-05-22 Akim Demaille <akim@epita.fr>
8072 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

8093 2003-05-22 Akim Demaille <akim@epita.fr>
8095 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
8096 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
8097 Reported by Jim Meyering.
8099 2003-05-22 Akim Demaille <akim@epita.fr>

8138 Reported by Sander Niemeijer.
8139 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

8141 AC_INCLUDES_DEFAULT.
8143 2003-05-17 Akim Demaille <akim@epita.fr>
8145 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
8146 * doc/autoconf.texi (Obsolete Macros): Adjust.
8147 Reported by Werner LEMBERG and Debian Bug 190886.
8149 2003-05-16 Akim Demaille <akim@epita.fr>
8151 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
8152 user name space clashes.
8153 Reported by Bruno Haible.
8155 2003-05-16 Akim Demaille <akim@epita.fr>
8157 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
8158 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
8159 them uniform, and more robust to Perl special characters.
8160 Reported by Martin Mokrejs.
8162 2003-05-14 Akim Demaille <akim@epita.fr>
8164 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.

8168 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

8173 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
8174 message.
8175 From Matthias Andree.
8177 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>

8180 and truncate.
8182 2003-05-06 Akim Demaille <akim@epita.fr>
8184 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
8185 longer updates aclocal.m4 if useless, (ii) if a file m4_included
8186 by aclocal.m4 is changed it might require the importing of another
8187 m4 extension file, i.e., aclocal must be run.
8189 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
8190 (&parse_args): Use --force with aclocal if required and supported.
8191 (&autoreconf_current_directory): Use &run_aclocal.
8193 2003-05-06 Akim Demaille <akim@epita.fr>
8195 Lock autom4te's cache.
8197 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
8198 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
8199 argument instead of a file name, so that the request file remains
8200 open during the whole autom4te run.
8201 ($icache_file): New.
8202 (&freeze): Lock the $icache_file.
8204 2003-04-29 Derek Price <derek@ximbiot.com>
8206 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
8207 seperator with m4_append_uniq(). It doesn't work.
8208 (AT_CLEANUP): Add `;' to end of at_help_all.
8209 (AT_INIT): Allow --keywords to be specified more than once. When
8210 grepping $at_help_all for keywords, use the field and keyword
8211 seperators to ensure a complete keyword match. Alter at_prev handling
8212 to support the new --keywords behavior.
8214 2003-04-27 Karl Berry <karl@freefriends.org>
8216 * doc/autoconf.texi: Make the dir entries in the autoconf manual
8217 align better with others. I also made some of the individual
8218 entries on one line, for brevity and to make it easier for me to
8219 sort my dir-example file in the Texinfo distribution :).
8221 2003-04-12 Jim Meyering <jim@meyering.net>
8223 * NEWS: Mention the new macro.

8317 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
8318 * tests/m4sh.at (AS_HELP_STRING): New test.
8320 * tests/acgeneral.at: Regenerated.
8322 2003-03-26 Derek Price <derek@ximbiot.com>
8324 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
8325 sense. Verbosify the diversion definitions comment.

8365 (Automake): Automake 1.5+ no longer requires special tools to be
8366 present on the developer's host.
8368 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
8370 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

8375 * bin/autoreconf.in (BEGIN): Likewise.
8376 * bin/autoscan.in (BEGIN): Likewise.
8377 * bin/autoupdate.in (BEGIN): Likewise.

8382 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
8383 to cope with DOS-style absolute paths, when constructing
8384 ${ac_make}.
8386 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
8387 When constructing paths with IFS=:, quote the path. If we're
8388 constructing a DOS-style absolute path, we don't want to split it
8389 on the colon.
8391 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
8392 in description.
8394 2003-02-25 Pavel Roskin <proski@gnu.org>

8406 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
8407 to fix a mismatch between example and discussion.
8409 2003-02-24 Kevin Ryde <user42@zip.com.au>
8411 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8412 format starting with "-".
8414 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8416 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8417 is not portable inside Makefile.
8419 2003-02-20 Akim Demaille <akim@epita.fr>
8421 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8422 compiler says yeah, but preproc says nope, compiler is right.
8423 Conversely, prompt the reader to send a bug report to the
8424 maintainers of the package, not of Autoconf.
8426 2003-02-20 Klee Dienes <kdienes@apple.com>
8428 * bin/autoreconf.in (autoreconf_current_directory): Properly
8429 handle an empty aclocal.m4.

8434 $ac_prefix_program.
8435 From Larry Jones.
8437 2002-12-23 Paul Eggert <eggert@twinsun.com>
8439 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8440 innocuous variant befor including <limits.h> or <assert.h>. This
8441 works around a bug reported by Albert Chin: HP-UX 11i
8442 (and earlier versions) have a <limits.h> that declares
8443 gettimeofday and many other functions.
8445 2002-12-03 Paul Eggert <eggert@twinsun.com>
8447 Version 2.57.
8449 * NEWS, configure.ac: Update version.
8451 * doc/fdl.texi: Upgrade to FDL version 1.2.
8453 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8454 nontrivially in main's body, so that f's external declaration is
8455 not optimized away in AIX. This should fix the bug reported by
8456 Martin Frydl in
8457 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8459 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8460 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8461 defined, to support freestanding compilers. This should fix the
8462 bug reported by Momchil Velkov in
8463 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8465 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8466 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

8471 * Makefile.maint (www-gnu): New macro.
8472 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
8473 the location has moved.
8475 2002-12-02 Martin Frydl <martin@systinet.com>
8477 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
8478 \(.*\) match is too long and there is something more to be checked.
8479 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
8481 2002-11-15 Akim Demaille <akim@epita.fr>

8487 * config/move-if-change: Indenting changes.
8488 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
8489 * configure.ac (AM_INIT_AUTOMAKE): here.
8490 Require 1.7.1.
8492 2002-11-14 Akim Demaille <akim@epita.fr>
8494 Version 2.55.
8496 * config/config.guess, config/config.sub, config/install-sh:
8497 Update from masters.
8499 2002-11-14 Akim Demaille <akim@epita.fr>
8501 * Makefile.maint: Sync with Bison, i.e.:
8502 (po-check): Scan .l and .y files instead of the
8503 .c and the .h files that they generate. This fixes the bug
8504 reported by Tim Van Holder in:
8505 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8506 Look for N_ as well as for _. Try to avoid matching #define for
8507 N_ and _.
8508 From Paul Eggert.
8510 2002-11-14 Akim Demaille <akim@epita.fr>
8512 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8513 From Paul Eggert and Albert Chin-A-Young.
8515 2002-11-14 Akim Demaille <akim@epita.fr>

8518 From Paul Eggert and Albert Chin-A-Young.
8520 2002-11-14 Kevin Ryde <user42@zip.com.au>
8522 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8523 than assigning in main, to avoid HP cc +O3 optimizing it away.
8525 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8527 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8528 option. Process --recheck after parsing all options. Pass -q
8529 option to configure on --recheck.
8530 (AC_OUTPUT): Pass -q from configure to config.status.
8531 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8532 arguments to record.
8533 * doc/autoconf.texi (config.status Invocation): Document
8534 config.status -q option.
8536 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

8539 Makefile.in if Makefile.am exists.
8540 (output): Strip `.am' from Makefiles. Don't
8541 output AC_CONFIG_FILES if no Makefiles were found.
8543 2002-11-07 Akim Demaille <akim@epita.fr>
8545 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

8550 2002-11-06 Akim Demaille <akim@epita.fr>
8552 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
8553 declaration in extern "C" too.

8556 2002-11-06 Akim Demaille <akim@epita.fr>
8558 * tests/torture.at (Configuring subdirectories): Don't use grep
8559 -w.
8560 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
8561 Reported by Ezra Peisach.
8563 2002-11-05 Akim Demaille <akim@epita.fr>
8565 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8566 Remove.
8567 We _have_ to stop using the old compatibility scheme that tried to
8568 avoid useless backslashes because Libtool 1.4.3 contains a
8569 AC_DEFINE([error_t], [int],
8570 [Define to a type to use for \`error_t' if it is not
8571 otherwise available.])
8572 We _have_ to quote the single quote and backslashes with \. The
8573 old compatibility scheme saw that ` was backslashed, and therefore
8574 did not quote the single quote. Hence before this patch, Autoconf
8575 was not compatible with Libtool.
8577 2002-11-04 Paul Eggert <eggert@twinsun.com>
8579 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8584 2002-11-04 Akim Demaille <akim@epita.fr>
8586 Version 2.54c.
8588 * Makefile.maint (update, cvs-update, po-update, do-po-update):
8589 New.
8590 * config/texinfo.tex: Update.
8592 2002-11-03 Akim Demaille <akim@epita.fr>
8594 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
8595 from...
8596 (&autoreconf): here.
8597 ($help, $make, &parse_args, &autoreconf_current_directory):
8598 Support -m/--make.
8599 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8601 2002-10-31 Bruno Haible <bruno@clisp.org>

8614 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
8615 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
8617 2002-10-31 Akim Demaille <akim@epita.fr>
8619 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
8620 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8621 Make variable, not a shell variable.
8622 Suggested by Bruno Haible.
8624 2002-10-31 Akim Demaille <akim@epita.fr>
8626 * bin/autom4te.in (load_configuration): Reject #args out of any
8627 language.
8629 2002-10-31 Akim Demaille <akim@epita.fr>
8631 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
8632 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
8633 (_AC_RUN_IFELSE): Use it.
8634 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
8635 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
8636 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
8637 inline it.

8643 Suggested by Tim van Holder.
8645 2002-10-29 Paul Eggert <eggert@twinsun.com>
8647 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
8648 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
8649 Problem reported by Bruno Haible.
8651 2002-10-29 Akim Demaille <akim@epita.fr>
8653 * doc/autoconf.texi (Header Templates): Put also in words what the
8654 pictures says to assist free style readers.
8655 (Customizing autom4te): s/--cache=/--cache /.
8657 2002-10-29 Akim Demaille <akim@epita.fr>
8659 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
8660 sys/wait.h.
8661 sparc_address_test returns void.
8662 Use it with an argument, as prototyped.
8663 From Bruno Haible.
8665 2002-10-29 Akim Demaille <akim@epita.fr>
8667 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

8673 * tests/torture.at (Deep Package): New test.

8679 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
8680 * doc/autoconf.texi (Invoking autom4te): Rename as...
8681 (autom4te Invocation): this, for consistency with the other nodes.
8683 2002-10-29 Akim Demaille <akim@epita.fr>
8685 * lib/autom4te.in (Autoconf): s/automate/autom4te/.
8686 Reported by Ralf Corsepius.
8688 2002-10-29 Akim Demaille <akim@epita.fr>
8690 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

8696 * configure.ac: Bump to 2.54c.

8907 2002-10-22 Akim Demaille <akim@epita.fr>
8909 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

8913 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""

8965 longer required can still cause errors.
8966 Reported by Alexandre Duret-Lutz.
8968 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8969 to frozen files in @ARGV, as @ARGV must remain being a list of

8971 (&files_to_options): New function.
8972 (&freeze): Use &error.
8973 (&up_to_date): If a file that was included according to the cache
8974 is no longer there, then the output is out dated.

8976 --force is given.
8977 * tests/tools.at (autom4te cache): New.

8986 that error messages can be easily located, and use GNU Make
8987 format, so that Emacs' compile mode understands us.
8988 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8989 if some file was changed instead of `print'.
8990 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

9024 file name to enable parallel executions.
9025 From Sam Varshavchik.
9027 2002-10-08 Akim Demaille <akim@epita.fr>
9029 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
9030 aclocal invocation, as Gettext macros might not be visible to
9031 aclocal.
9032 Instead of blindly running autopoint, scan configure.ac (not the
9033 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
9034 Reported by Paul D. Smith.
9036 2002-10-08 Paul Eggert <eggert@twinsun.com>
9038 Work around problems found when POSIXLY_CORRECT=1 is set.
9039 None of this seems to have anything to do with POSIX, really,

9041 * bin/autom4te.in (parse_args): Configure GetOpt with
9042 "permute", too.
9043 * doc/autoconf.texi (Invoking autom4te):

9066 * tests/torture.at (Configuring subdirectories): Be robust to
9067 users who use config.site to require for a cache: in this case,
9068 the two last configure runs, using two different sets of
9069 arguments, trigger a legitimate error.
9071 2002-09-28 Akim Demaille <akim@epita.fr>

9106 tests/autom4te itself.
9107 * lib/autoscan/Makefile.am: Include freeze.mk.
9108 (autoscan.list): New target --this file is no longer a source.

9135 2002-09-28 Akim Demaille <akim@epita.fr>
9137 From now on, autoscan files must always map a macro name to a
9138 word: there is no `default' macro for autoscan.
9140 * bin/autoscan.in (&init_tables): Reject entries with no macro at
9141 all.
9142 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
9143 explicit.
9145 2002-09-28 Akim Demaille <akim@epita.fr>
9147 * bin/autoscan.in (%c_keywords): Remove.

9215 2002-09-13 Paul Eggert <eggert@twinsun.com>
9217 * doc/autoconf.texi (Particular Headers): Remove obsolete
9218 reference to `struct timezone' in the description of
9219 AC_HEADER_TIME.
9221 2002-09-13 Akim Demaille <akim@epita.fr>
9223 Version 2.54.
9225 * config/config.sub, config/config.guess: Update.
9226 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
9227 * Makefile.am: Adjust.
9229 2002-09-13 Akim Demaille <akim@epita.fr>
9231 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
9232 reading config.log when the compiler is rejected.
9233 Suggested by Guido Draheim.
9235 2002-09-13 Akim Demaille <akim@epita.fr>
9237 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
9238 (chdir_init) might hang when stat'ing mounted directories.
9239 Reported by Vance Shipley.
9241 2002-09-12 Akim Demaille <akim@epita.fr>
9243 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
9244 the lists.
9246 2002-09-12 Akim Demaille <akim@epita.fr>
9248 * doc/autoconf.texi (Defining Symbols): Present two different
9249 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
9250 difference between 1 argument calls, and 2-3 argument calls.
9252 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
9254 * doc/autoconf.texi: Review grammar and punctuation.
9256 2002-09-11 Paul Eggert <eggert@twinsun.com>
9258 * doc/autoconf.texi: Fix minor formatting, spelling, and
9259 grammatical typos.
9260 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
9261 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
9262 is obsolescent.
9264 2002-09-11 Akim Demaille <akim@epita.fr>
9266 * doc/autoconf.texi (Questions): Rename as...
9267 (FAQ): this.
9268 (Defining Directories): New.
9270 2002-09-09 Akim Demaille <akim@epita.fr>
9272 * doc/autoconf.texi (Making testsuite Scripts): Update.
9273 Suggested by Nishio Futoshi.
9275 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
9277 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
9278 plain `@' is wanted.
9280 2002-09-09 Akim Demaille <akim@epita.fr>
9282 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
9283 `duplicates', since the algorithm was too naive and could keep
9284 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
9285 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9286 Reported by Ralf Corsepius.
9287 * tests/torture.at (Configuring subdirectories): Exercise these
9288 cases.
9290 2002-09-09 Akim Demaille <akim@epita.fr>
9292 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
9293 looking for a replacement file.
9294 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9295 directory is relative.
9296 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9297 directory definition.
9298 Reported by Andreas Schwab and Jim Meyering.
9300 2002-09-06 Akim Demaille <akim@epita.fr>
9302 * doc/autoconf.texi (Setting Output Variables): Clarify what
9303 precious variables are.
9304 Suggested by Pontus Skoeld.
9306 2002-09-05 Akim Demaille <akim@epita.fr>
9308 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9309 (ifnames, autoscan, autom4te): Since we don't only depend on
9310 configure.ac variables (such as VERSION etc.), but also on prefix
9311 and so forth, depend on Makefile, not configure.ac.
9312 Reported by Alexandre Duret-Lutz.
9313 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9315 2002-09-05 Kevin Ryde <user42@zip.com.au>
9317 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9318 doesn't seem to be confined to ia64, just say "some versions".
9320 2002-09-04 Akim Demaille <akim@epita.fr>
9322 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9323 Automake 1.6c.
9324 * Makefile.am (maintainer-clean-local): Remove.
9325 (MAINTAINERCLEANFILES): Remove COPYING.
9327 2002-09-03 Paul Eggert <eggert@twinsun.com>
9329 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9330 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9331 Brinkmann.
9333 2002-09-03 Akim Demaille <akim@epita.fr>
9335 * configure.ac: Bump to 2.53d.
9336 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9337 as of today, on Automake's team suggestion.
9339 2002-09-03 Akim Demaille <akim@epita.fr>
9341 Version 2.53c.
9343 2002-09-02 Akim Demaille <akim@epita.fr>
9345 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9346 SITE_MACRO_DIR.
9347 * configure.ac: Disable SITE_MACRO_DIR.
9349 2002-09-02 Jim Meyering <meyering@lucent.com>
9351 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9352 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9353 Also, tweak grammar: s/make sure to/be sure to/.
9355 2002-09-02 Paul Eggert <eggert@twinsun.com>
9357 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9358 directory names are generally preferable to physical names.
9360 2002-09-02 Akim Demaille <akim@epita.fr>
9362 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9363 Reported by Raja R. Harinath.
9364 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9365 * bin/autoupdate.in: Use error instead of die.
9367 2002-09-01 Paul Eggert <eggert@twinsun.com>
9369 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9370 ordinary shell concatenation rather than echo+tr+sed command that
9371 runs afoul of a long-line-related sed bug in Solaris 8.
9373 * bin/autoheader.in (parse_args): --warning -> --warnings.
9375 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9376 stdout, as traditional "ls" does.
9377 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9378 _AC_COMPILER_EXEEXT_O): Likewise.
9379 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9381 * bin/autoconf.as: Add --prepend-include option. This patch was
9382 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9383 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9385 * bin/autoconf.in, configure: Regenerate.
9387 * doc/autoconf.texi (Special Shell Variables): Mention
9388 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9390 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9391 MAILPATH and set PS1, PS2, PS4 to default values, to work
9392 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9393 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9394 the Autoconf documentation specifies; fall back to "unset" only if
9395 this fails. Use a shell for-loop for this rather than an m4 loop,
9396 to shorten the output script.
9398 2002-08-30 Paul Eggert <eggert@twinsun.com>
9400 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9401 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9402 for the CDPATH problem. Document PWD.
9403 (Limitations of Builtins): Document the problem that "cd $foo" and
9404 "ls $foo" may refer to different directories in shells conforming
9405 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9406 example, since the old example is now out of date.
9408 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9409 FOO" and "ls FOO" talk about different directories; this catches
9410 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9411 spaghetti.
9413 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9414 of rolling our own unset.
9415 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9416 in practice we needn't worry about CDPATH if unset doesn't work.
9418 * Makefile.in, aclocal.m4, bin/Makefile.in,
9419 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9420 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9421 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9422 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9423 tests/Makefile.in: Regenerate with Automake 1.6.3.
9425 * config/config.guess, config/config.sub, config/mkinstalldirs:
9426 Update.
9428 * configure: Regenerate with self.
9430 2002-08-30 Kevin Ryde <user42@zip.com.au>
9432 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9433 default output.
9435 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9437 * bin/autom4te.in (Request::load): Correctly test for "do" read
9438 failure.
9440 2002-08-29 Akim Demaille <akim@epita.fr>
9442 * lib/Autom4te/General.pm (&xqx): New.
9443 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9444 hand, which is not portable.
9445 (&error): New.
9446 * bin/autom4te.in: Use them.
9447 Use &error instead of die.
9448 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9449 Adjust.
9451 2002-08-17 Paul Eggert <eggert@twinsun.com>
9453 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9454 default list of compilers to try, since it was long ago superseded
9455 by the ksh fc builtin. Suggested by Steven G. Johnson.
9457 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9459 * doc/autoconf.texi (Invoking autom4te): End the option table,
9460 fixing a bug introduced by the previous patch.
9461 (Limitations of Make): Add a 'target lookup' subentry in the
9462 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9464 2002-07-29 Mark D. Roth <roth@feep.net>
9466 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9467 options and use $AUTOM4TE_PATH.
9468 * doc/autoconf.texi: Remove documentation of autom4te
9469 --include-envvar and --site-macro-subdir options and document
9470 use of $AUTOM4TE_PATH.
9471 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9472 arguments from each language section.
9474 2002-07-29 Paul Eggert <eggert@twinsun.com>
9476 * doc/install.texi: Include copyright symbol in copyright notice.
9478 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9479 Replace with:
9480 (AM_MAKEINFOFLAGS): New macro.
9481 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9482 * Makefile.am (INSTALL): Use the new macros.
9483 Use -o rather than --output, since "missing" does not grok --output.
9485 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9487 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9488 comments do not always work. Never trust the exit status of
9489 `make -k'.
9491 2002-07-24 Kevin Ryde <user42@zip.com.au>
9493 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9494 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9496 2002-07-23 Paul Eggert <eggert@twinsun.com>
9498 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9499 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9500 apparently treats PATH="nonexistent" as if it contained ".".
9501 Bug reported by Stefan `Sec' Zehl.
9503 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9505 * doc/autoconf.texi (Limitations of Make): Mention the special
9506 handling of the obj/ directory by BSD make.

9522 2002-07-18 Akim Demaille <akim@epita.fr>
9524 Version 2.53b.
9526 2002-07-18 Akim Demaille <akim@epita.fr>
9528 * config/config.guess, config/config.sub: Update.
9530 2002-07-18 Akim Demaille <akim@epita.fr>
9532 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
9533 Automake's parts.

9536 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
9537 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
9539 2002-07-18 Akim Demaille <akim@epita.fr>,
9540 Alexandre Duret-Lutz <duret_g@epita.fr>
9542 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
9543 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

9548 description of the tarname default.
9550 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
9552 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
9553 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
9554 latter was not run.
9556 2002-07-17 Akim Demaille <akim@epita.fr>
9558 * lib/Autom4te/General.pm (find_file): Browse the directories in
9559 the order they are given.

9579 macro directory, remove note that include path directories are
9580 used in reverse order, and document --prepend-include option.
9581 * lib/autom4te.in: Use --prepend-include instead of --include.
9582 * tests/wrapsh.in: Use --prepend-include instead of --include.
9584 2002-07-17 Akim Demaille <akim@epita.fr>

9627 2002-06-27 Paul Eggert <eggert@twinsun.com>

9631 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
9632 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9634 * tests/mktests.sh: Use grep instead of fgrep, as per
9635 "Limitations of Builtins".
9637 2002-06-15 Paul Eggert <eggert@twinsun.com>
9639 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
9640 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
9641 so that we consistently test the just-built programs.
9642 * tests/wrappl.as: Likewise.
9644 2002-06-12 Paul Eggert <eggert@twinsun.com>
9646 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
9647 name, so that symlinks to 'autoconf' work properly. Bug reported
9648 by Bruno Haible.
9649 * bin/autoheader.in (AUTOM4TE): Likewise.
9650 * bin/autoreconf.in (autoconf, autoheader): Likewise.
9651 * bin/autoscan.in (autom4te): Likewise.
9652 * bin/autoupdate.in (autom4te): Likewise.
9654 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
9655 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
9656 on Solaris 2.5.1.
9658 2002-06-11 Andreas Schwab <schwab@suse.de>
9660 * doc/autoconf.texi: Add more dir entries.
9662 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9664 * bin/autom4te.in ($cache): Don't define using `$me', the name
9665 of the cache should not depend on the name under which autom4te
9666 was installed.
9668 2002-06-07 Akim Demaille <akim@epita.fr>
9670 * tests/tools.at (autoconf: forbidden tokens, basic)
9671 (autoconf: forbidden tokens, exceptions): Adjust to the change of
9672 words in autom4te.in.
9674 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
9676 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
9677 _AC_LANG_PROGRAM_C_F77_HOOKS.
9679 2002-06-07 Akim Demaille <akim@epita.fr>

9707 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
9708 (AC_REPLACE_FNMATCH_GNU): these.
9709 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
9710 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
9711 * tests/mktests.sh (ac_exclude_list): Don't check
9712 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
9714 2002-06-06 Paul Eggert <eggert@twinsun.com>
9716 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
9717 if ln doesn't work.
9718 * NEWS: Likewise.
9719 * doc/autoconf.texi (Configuration Links): Likewise.
9720 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
9722 2002-06-05 Paul Eggert <eggert@twinsun.com>
9724 * config/config.guess, config/config.sub, config/texinfo.tex:
9725 Update from masters.
9727 2002-05-29 Paul Eggert <eggert@twinsun.com>
9729 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
9730 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
9731 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):
9732 Likewise.
9733 * lib/autoconf/Makefile.am (check-local): Likewise.
9734 * lib/autoconf/status.m4 (AC_CONFIG_HEADER): Likewise.
9735 * lib/autoconf/types.m4 (commentary only): Likewise.

9739 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
9740 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
9742 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
9743 * doc/autoconf.texi (Particular Programs): Document them.
9744 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
9745 * NEWS: Likewise.
9747 2002-05-27 Paul Eggert <eggert@twinsun.com>
9749 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
9750 * NEWS, doc/autoconf.texi (Particular Types): Document it.
9751 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
9752 instead of AC_MBSTATE_T, which never existed.
9754 2002-05-23 Akim Demaille <akim@epita.fr>
9756 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
9757 version of Autoconf that is discussed.
9759 2002-05-22 Paul Eggert <eggert@twinsun.com>
9761 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
9762 from the default list of compilers to try. Suggested by
9763 Kate Hedstrom.
9764 * NEWS: Document the above.
9765 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
9767 2002-05-17 Paul Eggert <eggert@twinsun.com>
9769 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9770 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9771 This improves on an earlier suggestion by H. Peter Anvin.
9773 2002-05-16 Paul Eggert <eggert@twinsun.com>
9775 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9776 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9777 Both macros now accept an optional source-dir arg.
9778 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9780 * NEWS: Document this.
9781 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9783 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9784 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9785 not for GNU extensions; this undoes part of the 2000-11-03 change,
9786 reverting to 2.13-compatible behavior.
9787 Add new optional argument DIR.
9788 (AC_FUNC_FNMATCH_GNU): New macro.
9790 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9792 2002-05-08 Paul Eggert <eggert@twinsun.com>
9794 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9795 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9796 and it causes a 'test' syntax error if it fails.
9797 Bug reported by Stephen Gildea.
9799 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9800 If prototypes are supported, use them to check this at compile-time,
9801 instead of trying to check it at run-time. If we must do a run-time
9802 check, assume that setvbuf is standard when cross-compiling, as
9803 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9804 Bug reported by Paul D. Smith.
9806 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9807 argument specifying location of getloadavg.c. This removes a
9808 FIXME. This idea was taken from Jim Meyering's implementation in
9809 textutils.
9810 * doc/autoconf.texi (Particular Functions): Document this.
9811 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9812 that's what the code does; this fixes a bug reported by
9813 Paul D. Smith.
9815 2002-05-03 Akim Demaille <akim@epita.fr>
9817 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9818 autopoint instead of gettextize.
9819 ($uses_alocal): Rename as...
9820 ($uses_aclocal): this.
9821 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9822 Suggested by Bruno Haible.
9824 2002-05-03 Akim Demaille <akim@epita.fr>
9826 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9828 2002-04-29 Paul Eggert <eggert@twinsun.com>
9830 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9831 files to be 1 second older; just set them to be the same time.
9832 Also, sleep 1 second after the first aclocal, to work around
9833 problems with sub-second time stamps on the input files.
9835 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9837 * doc/autoconf.texi: Mention "set -e -x" lossage
9838 under node "Limitations of Builtins".
9840 2002-04-29 Akim Demaille <akim@epita.fr>
9842 * doc/install.texi: Better wording for setting variables when
9843 running configure.
9844 From Christian Cornelssen.
9846 2002-04-29 Akim Demaille <akim@epita.fr>
9848 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9849 of lack of $LINENO support, then the test will compare the $LINENO
9850 in testsuite vs. the lineno in the test file. This is wrong, of
9851 course.
9852 Be sure to protect it.
9853 Reported by Patrick Welche.
9855 2002-04-25 Akim Demaille <akim@epita.fr>
9857 * doc/autoconf.texi (Obsolete Macros): Typo.
9858 Reported by Vladimir Volovich.
9860 2002-04-25 Akim Demaille <akim@epita.fr>
9862 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9863 than some of the input files, hence, on the second run of aclocal,
9864 if some of its input are younger, make them older.
9865 Suggested by Paul Eggert.
9867 2002-04-25 Akim Demaille <akim@epita.fr>
9869 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9870 Thanks to Paul Eggert.
9872 2002-04-25 Akim Demaille <akim@epita.fr>
9874 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9875 and ac_subst_vars be sh variables containing the list of
9876 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9877 DEFAULT diversion.
9878 (_AC_INIT_PREPARE): Use them to log them.
9879 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9880 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9881 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9882 _AC_SUBST_FILES and _AC_SUBST_VARS.
9883 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9885 2002-04-24 Akim Demaille <akim@epita.fr>
9887 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9888 autoheader, so that automake does not complain about a missing
9889 config.h.in that was to be created.
9891 2002-04-23 Akim Demaille <akim@epita.fr>
9893 * bin/autoheader.in (parse_args): --warning takes an argument.
9894 Fixes PR/220.
9896 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9898 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
9899 and bb.out when cleaning up.
9901 2002-04-22 Akim Demaille <akim@epita.fr>
9903 Version 2.53a.
9905 2002-04-22 Akim Demaille <akim@epita.fr>
9907 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
9909 2002-04-22 Akim Demaille <akim@epita.fr>
9911 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
9912 comma.
9913 Reported by Gregory Giannoni.
9915 2002-04-22 Akim Demaille <akim@epita.fr>
9917 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
9918 Fixes false failures on Darwin.
9920 2002-04-21 Paul Eggert <eggert@twinsun.com>

9924 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

9943 Minor spelling and grammar fixes.
9945 * doc/autoconf.texi: Follow the outline suggested in the GNU
9946 Sample Texts sections of the Texinfo 4.2 manual. Most
9947 importantly, this makes sure that the copyright notices appear in
9948 all output formats. You probably need Texinfo 4.2 to generate
9949 the manual now.
9951 Fix some bugs when using "$@" when there might be zero positional
9952 arguments in cases where this matters.

9973 that is not portable to Zsh.
9975 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9977 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9978 from aclocal.m4 too.
9980 2002-04-12 Akim Demaille <akim@epita.fr>

9984 2002-04-10 Akim Demaille <akim@epita.fr>
9986 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9987 workaround for ${1+"$@"}.
9988 * doc/autoconf.texi (Shell Substitutions): Explain it.
9989 From Oliver Kiddle and Peter Stephenson.
9991 Have M4sh perform minimal shell sanitizing.
9993 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9994 part into...
9995 (_AS_PREPARE): this new macro.
9996 (AS_PREPARE): New.
9997 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9998 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
10000 Adjust Autoconf and Autotest.
10002 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
10003 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
10004 * lib/autotest/general.m4 (AT_INIT): Likewise.
10005 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10006 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
10007 AS_SHELL_SANITIZE.
10009 Use this M4sh to generate Autoconf's shell scripts.
10011 * tests/wrapsh.as: New, precursor of wrapsh.in.
10012 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
10013 on Autotest and M4sh.
10014 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
10015 (wrapsh.in): New target.
10016 * bin/autoconf.as: New, precursor of autoconf.in.
10017 (autoconf.in): New target.
10019 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

10022 with indented comments in rules.
10024 2002-04-09 Andreas Schwab <schwab@suse.de>
10026 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
10027 ac_top_builddir when setting ac_abs_top_builddir.
10029 2002-04-06 Kevin Ryde <user42@zip.com.au>
10031 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
10032 (Portable Shell): Cross reference to Systemology.
10034 2002-04-05 Akim Demaille <akim@epita.fr>
10036 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
10037 directories when descending in a SUBDIRS.

10040 2002-04-04 Andreas Schwab <schwab@suse.de>

10043 contains no literal separators.
10045 2002-04-03 Akim Demaille <akim@epita.fr>
10047 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
10048 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
10049 Use dnl, not the KILL diversion.
10050 Extracted from...
10051 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
10052 (AC_CONFIG_LINKS): here.
10053 Adjust.
10054 Don't use the KILL diversion, as it kills spurious output, which
10055 results in failures being hidden.
10056 Use m4_defn where appropriate.
10057 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
10058 after the second argument.
10059 Use m4_defn.
10060 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
10061 syntax, as it is provided by M4sugar.
10062 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
10064 2002-04-03 Andreas Schwab <schwab@suse.de>
10066 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
10067 expanded if $# <= 2.
10069 * bin/autoreconf.in (autoreconf): Run automake after rerunning
10070 aclocal.

10077 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
10078 (_AC_COMPILER_OBJEXT): Use them.

10081 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
10083 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

10086 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
10087 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
10088 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
10089 (AC_C_CONST): Same.
10090 (AC_C_INLINE): Same.
10091 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
10092 * doc/autoconf.texi, NEWS: Document.
10093 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
10094 AC_C_CROSS.
10096 2002-04-02 Akim Demaille <akim@epita.fr>
10098 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke

10101 2002-03-28 Kevin Ryde <user42@zip.com.au>
10103 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,

10106 2002-03-27 Paul Eggert <eggert@twinsun.com>
10108 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

10118 * doc/autoconf.texi (Introduction): The GNATS base moved.
10120 2002-03-25 Paul Eggert <eggert@twinsun.com>
10122 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
10123 as POSIX requires, as it doesn't work with Zsh.
10124 * doc/autoconf.texi (Assignments): Document the problem.
10126 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10128 * doc/autoconf.texi (Limitations of Make): Mention more issue
10129 about VPATH, overriding of macros in sub-makes, and handling of
10130 SHELL.
10132 2002-03-21 Paul Eggert <eggert@twinsun.com>
10134 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
10135 problem with here-document buffer boundaries.
10137 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
10138 when reinvoking the shell, to work around problems with installers
10139 who put strange things like "cd" commands in their environments.
10141 2002-03-19 Akim Demaille <akim@epita.fr>

10149 invocations.
10150 From Nicolas Joly.
10152 2002-03-19 Akim Demaille <akim@epita.fr>

10155 From Nishio Futoshi.
10157 2002-03-19 Akim Demaille <akim@epita.fr>
10159 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

10163 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
10164 (Limitations of Usual Tools): Add mkdir section.
10166 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
10167 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
10168 back on AS_DIRNAME to compute prefixes otherwise; this is
10169 roughly what mkinstalldirs does. That way, we need not have
10170 our own filename disassembler. The old disassembler did not
10171 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
10173 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
10174 Create at_test_all by a series of assignments,
10175 not by a single assignment of a long string. The latter causes ksh
10176 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
10177 presumably because of a buffer overrun.

10181 * lib/autotest/general.m4 (at_times_skip):
10182 Renamed from at_times. Now a boolean.
10183 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
10184 says 'times: not found'.

10188 * bin/autoreconf.in (&study_gettextize): New.

10210 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
10211 m4_require.
10213 2002-03-11 Andreas Schwab <schwab@suse.de>

10216 does not do it if --with-lispdir is given.

10220 Version 2.53.

10231 2002-03-08 Akim Demaille <akim@epita.fr>
10233 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
10234 aliases the actual variables, and modifications of the former
10235 affect the latter.

10239 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
10240 because of C-c: have m4 output in tmp files, then mv them.

10270 parallel builds.
10272 2002-03-04 Akim Demaille <akim@epita.fr>
10274 * doc/autoconf.texi (Transforming Names): Equality between target
10275 and host is irrelevant.
10276 (Specifying Names, Canonicalizing): Remove all references to the
10277 backward compatibility hooks. Rather, collect them all into...
10278 (Hosts and Cross-Compilation): this new section.
10279 * doc/install.texi (System Type): Ditto.
10280 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
10281 that `--host' implies cross-compilation.
10283 2002-03-04 Akim Demaille <akim@epita.fr>
10285 * doc/autoconf.texi (Evaluation Macros): New.
10286 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10287 useless.
10288 (_m4_foreach): Define the variant with immediate evaluation so
10289 that it contains exactly the items, not an expression which
10290 evaluation is the current item.
10291 (m4_re_string, m4_re_word): Don't over quote them.
10293 2002-03-04 Akim Demaille <akim@epita.fr>
10295 Instead of having stacking `shift's evaluated at the end, let
10296 `foreach' loops immediately evaluate them.
10298 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10299 $*. This is the n-th time I change my mind, but hopefully this is
10300 the last...
10301 (m4_lquote): New.
10302 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10303 efficient.
10304 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10305 it was only a hack for m4_text_wrap.
10306 (m4_car2): Remove, replaced by...
10307 (m4_cdr): New.
10308 (_m4_foreach): Adjust.
10309 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10310 m4_bpatsubst for clarification.

10314 * doc/autoconf.texi (Changequote is Evil): New.

10346 translate \r\n to \n.
10348 2002-02-07 Akim Demaille <akim@epita.fr>

10362 AC_PREFIX_PROGRAM fails with dashed program names
10364 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

10380 2002-02-06 Akim Demaille <akim@epita.fr>

10383 sure not to introduce newlines in at_groups.

10386 2002-02-06 Akim Demaille <akim@epita.fr>
10388 * tests/torture.at (Configuring subdirectories): Skip if aclocal
10389 is not available.

10393 * doc/autoconf.texi (Specific Compiler Characteristics):
10394 Describe HP-UX cc bug workaround more accurately.
10395 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
10396 not unsigned long.
10397 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
10398 cross-compilers, too. This undoes some of the most recent change
10399 to this file.
10401 2002-02-05 Akim Demaille <akim@epita.fr>
10403 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

10408 * doc/autoconf.texi (Making testsuite Scripts): Document

10415 2002-02-05 Akim Demaille <akim@epita.fr>

10420 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
10421 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
10423 2002-02-05 Akim Demaille <akim@epita.fr>
10425 * bin/autom4te.in (&parse_args): Implement `frozen files are
10426 optional are the sum of the previous files on the command line'.
10427 Also, pass `--reload-state=' on them, so...
10428 (handle_m4): don't.
10429 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10430 (M4sh): Rely on M4sugar.
10431 (Autotest, M4sh, M4sugar): Use frozen files.

10445 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10446 for plain code, the other for cross-compilation code. The latter
10447 is now run with GCC only.

10461 Reported by Alexandre Duret-Lutz and Larry Schmitt.
10463 2002-01-28 Akim Demaille <akim@epita.fr>
10465 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10466 needs an argument.
10468 2002-01-28 Akim Demaille <akim@epita.fr>
10470 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10471 AUTOTEST_PATH *after* it was set.
10472 Don't put `.' in the PATH: the user should be precise and `./' if
10473 needed. In addition, given that the test suite does some `cd', if
10474 `.' is in the path, the `tested programs' sections will report
10475 programs found in the test suite's directory, while during the
10476 tests (performed in their own directory), these programs are no
10477 longer visible. In other words, the results is confusing and
10478 useless.
10479 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10481 2002-01-24 Akim Demaille <akim@epita.fr>

10515 Reported by Geir Ove Myhr.
10517 2002-01-21 Akim Demaille <akim@epita.fr>
10519 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
10521 2002-01-21 Akim Demaille <akim@epita.fr>
10523 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10524 message on invalid options.
10525 * bin/autom4te.in (parse_args): Don't use
10526 Autoconf::General::getopt with non valid options.
10528 2002-01-17 Jim Meyering <meyering@lucent.com>
10530 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10531 $ac_cv_exeext so we don't use an old, invalid, cached value.
10533 2002-01-11 Akim Demaille <akim@epita.fr>

10538 limitation.

10542 2002-01-06 Akim Demaille <akim@epita.fr>
10544 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10545 package.m4, since is really depends upon configure.ac, not
10546 configure.
10547 * doc/autoconf.texi (testsuite Scripts): Adjust.
10548 * tests/Makefile.am (package.m4): New.
10549 EXTRA_DIST it since its a source.
10551 2002-01-06 Akim Demaille <akim@epita.fr>
10553 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10554 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10555 and PACKAGE_BUGREPORT from here...
10556 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10557 arguments.
10558 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10559 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

10583 2001-12-14 Akim Demaille <akim@epita.fr>
10585 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10586 trailing files, don't apply `-rf' to files which might not be
10587 created by configure (core, core.*, and *.core), but just `rm -f'.
10588 Suggested by Jonathan Kamens.
10590 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10592 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

10627 Remove $filepath, useless.
10628 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10629 variables, they are really part of the tokens.
10630 Split the input line on spaces and then look for tokens.
10631 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10632 because of `lex$U.$(OBJEXT)'.
10633 (&scan_files): Use "@list" instead of join.
10634 * doc/Makefile.am (CLEANFILES): Add *.fns.
10636 2001-11-26 Akim Demaille <akim@epita.fr>
10638 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10639 Remove, replaced by...
10640 * tests/wrappl.in: Be common for all the Perl executables.
10641 In particular autoscan and autoheader want -I.
10642 * configure.ac: Adjust.

10674 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10675 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10676 at_top_builddir.
10677 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10678 top_srcdir, builddir and top_builddir.
10679 Use `at_*dir' relatively to the directory containing the
10680 suite, use `*dir' when relatively to the current group dir.
10682 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10684 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10685 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10686 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10687 spelling errors.
10689 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10691 * doc/autoconf.texi (Using System Type): Add an example of `case
10692 $host' usage so people quit using `case $target' everywhere.
10694 2001-11-22 Akim Demaille <akim@epita.fr>
10696 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10697 spotted by Jim Meyering.
10699 2001-11-16 Paul Eggert <eggert@twinsun.com>
10701 This patch implements a `long double' suggestion by Oliver Kiddle.
10703 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10704 static, to catch errors if the value isn't known at compile-time
10705 and the compiler supports dynamic arrays. Change its name from
10706 `_array_' to `test_array' to avoid potential name clashes.
10707 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10708 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10709 better than double. Catch a bug in GCC 2.95.2 x86.
10710 * doc/autoconf.texi (C Compiler): Document the above.
10711 * NEWS: Likewise.
10713 2001-11-13 Akim Demaille <akim@epita.fr>
10715 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10716 hand.
10717 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10719 2001-11-13 Akim Demaille <akim@epita.fr>
10721 * lib/autotest/general.m4 (AT_INIT): After having run the test
10722 group, go back to the initial directory, not to at_suite_dir.
10724 2001-11-13 Akim Demaille <akim@epita.fr>
10726 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10727 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10728 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10729 option.
10730 (AT_CHECK_CONFIGURE): Use absolute paths.
10731 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10732 The problem is still the old one: there is no means in M4 (that I
10733 know about) to create a defining macro, because there is no means
10734 to create `$1' etc., therefore, the defining macro ``swallows''
10735 all the arguments meant to the defined macro.
10737 2001-11-13 Akim Demaille <akim@epita.fr>
10739 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10740 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10741 configure.ac.
10742 * tests/aclocal.m4: Remove, as it is no longer used.
10744 2001-11-13 Akim Demaille <akim@epita.fr>
10746 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10747 variable names when referring to a single test group, or to
10748 `suite' when referring to the whole test suite.
10749 `at_last_test' is removed: m4 compute at_format itself.
10750 (at_stdout, at_stder1, at_stderr): New variables.
10751 (AT_CHECK): Use them.
10753 2001-11-13 Akim Demaille <akim@epita.fr>
10755 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10756 in PATH.
10757 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10758 Do it as soon as a test fails, don't wait till the end of the test
10759 suite.
10760 Don't remove $as_me.[0-9]*, since these files no longer exist.
10762 2001-11-13 Akim Demaille <akim@epita.fr>
10764 * tests/tools.at: Use absolute paths, since we are no longer run
10765 in place.
10767 2001-11-13 Akim Demaille <akim@epita.fr>
10769 Now that tests are running in their own private dir, there is no
10770 need to list the files to remove at the end of tests groups.
10772 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10773 (AT_data_files, at_data_files): Remove.
10774 (AT_CLEANUP, AT_DATA): Simplify.
10775 (AT_INIT): Adjust.
10776 Remove the group dir if !debug && !failed.
10777 * tests/atspecific.m4: Adjust.
10779 2001-11-13 Akim Demaille <akim@epita.fr>
10781 Start a new layout for Autotest: `testsuite' creates
10782 `testsuite.dir' in which the at-check-line etc. files are to be
10783 found, and `testsuite.dir/003' where the test group 3 is run.
10785 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10786 at_check_line_file, at_format, at_test_normalized, at_group_dir
10787 are new variables.
10788 Create the directories.
10789 Use absolute paths for at- files.
10790 (AT_CHECK): Adjust.
10792 2001-11-11 Michael Matz <matz@kde.org>
10794 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10795 (m4_car2): New.
10796 (m4_car): Properly quote arguments.
10798 2001-11-13 Akim Demaille <akim@epita.fr>
10800 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10801 with stricter rules on LIBOBJS.
10803 2001-11-12 Paul Eggert <eggert@twinsun.com>
10805 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10806 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10807 __PROTOTYPES too.
10809 2001-11-12 Akim Demaille <akim@epita.fr>
10811 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10813 2001-11-12 Akim Demaille <akim@epita.fr>
10815 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10816 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10817 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10818 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10819 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10820 specify to what the macro should be defined (typically to 1).
10822 2001-11-12 Akim Demaille <akim@epita.fr>
10824 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10825 From Jim Meyering.
10827 2001-11-12 Akim Demaille <akim@epita.fr>
10829 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10830 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10831 definition used by Automake where LEX is +/- "${missing} lex" and
10832 `missing' itself contains variables.
10834 2001-11-12 Akim Demaille <akim@epita.fr>
10836 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10837 Now that M4sh pushes BODY, the comments were output at the end of
10838 the test suites.
10840 2001-11-08 Akim Demaille <akim@epita.fr>
10842 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10843 that we can trace macros from aclocal.m4.
10844 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10845 obsoleted, and redirect to the former anyway.
10846 Reported by Ralf Corsepius.
10848 2001-11-08 Akim Demaille <akim@epita.fr>
10850 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10851 processed only if present.
10852 * tests/torture.at (Configuring subdirectories): Use autoreconf
10853 instead of successive calls to autoconf.
10854 Add a nonexistent subdirectory to exercise the patch above.
10855 Reported by Ralf Corsepius.
10857 2001-11-08 Kevin Ryde <user42@zip.com.au>
10859 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10860 doesn't accept .S files.
10862 2001-11-07 Akim Demaille <akim@epita.fr>
10864 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10865 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10866 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10867 * bin/autom4te.in (warn_forbidden): New.
10868 (handle_output): Use it.
10869 Read m4_pattern_forbid with messages.
10871 2001-11-05 Akim Demaille <akim@epita.fr>
10873 * bin/autom4te.in (--normalize): Remove.
10874 * lib/autom4te.in: Adjust.
10876 2001-11-05 Akim Demaille <akim@epita.fr>
10878 * tests/Makefile.am (testsuite): Rename this target as...
10879 ($(TESTSUITE)): this.
10880 From Nicolas Joly.
10882 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10884 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10885 the --prefix option, also remove it's argument.
10887 2001-11-05 Akim Demaille <akim@epita.fr>
10889 * doc/autoconf.texi (testsuite Invocation): Update.
10890 (Writing testsuite.at): Update.
10892 2001-11-03 Akim Demaille <akim@epita.fr>
10894 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10896 2001-11-03 Akim Demaille <akim@epita.fr>
10898 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10899 (&file_name_is_absolute): New, wrappers around routines from
10900 File::Spec.
10901 Use and export them.
10902 (&find_configure_ac): Optionally take a directory where to look at.
10903 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10904 the arguments.
10905 Default @ARGV to `.', not find_configure_ac.
10906 (&autoreconf): Argument is a directory.
10907 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10908 * doc/autoconf.texi (autoreconf Invocation): Update.
10910 2001-11-03 Akim Demaille <akim@epita.fr>
10912 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10913 (@export_forward_subs): New.
10914 Add basename, dirname, and fileparse.
10915 (@EXPORT): Adjust.
10916 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10917 Don't look for aclocal flags if we already know aclocal is not
10918 used.
10919 Move aclocal.m4t only if it exists.
10920 Reported by Ezra Peisach.
10922 2001-11-03 Akim Demaille <akim@epita.fr>
10924 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10925 passed on command line, defaulting to ./configure.ac if present.
10926 (&maybe_autoreconf, File::Find): Remove, unused.
10927 (&autoreconf): If autoconf is not used, don't try to trace.
10929 2001-11-02 Akim Demaille <akim@epita.fr>
10931 * configure.ac: Bump to 2.52g.
10933 2001-11-02 Akim Demaille <akim@epita.fr>
10935 Version 2.52f.
10937 2001-11-02 Akim Demaille <akim@epita.fr>
10939 * config/config.guess, config/config.sub, doc/standards.texi:
10940 * config/lispdir.m4: Update from masters.
10941 * configure.ac: Bump to 2.52f.
10943 2001-11-02 Akim Demaille <akim@epita.fr>
10945 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10946 Don't run aclocal when aclocal.m4 is not from aclocal.
10947 From Ezra Peisach.
10948 Don't run libtoolize and gettextize if --install is not given.
10950 2001-11-01 Paul Eggert <eggert@twinsun.com>
10952 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10953 be invoked before _AS_LINENO_PREPARE.
10954 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10955 than character ranges.
10957 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10958 invoking AS_BASENAME. Set the locale variables to 'C' if
10959 possible, as POSIX requires this to get the traditional
10960 behavior.
10961 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10963 2001-10-31 Paul Eggert <eggert@twinsun.com>
10965 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10966 with {}, as that triggers a bug in Bash 2.05.
10968 (_AS_LINENO_PREPARE): Use Sed rather than
10969 Awk. Fix the sed prepass to work even if there are multiple
10970 instances of $LINENO on the same line. Do not substitute for
10971 other variables like $LINENOT. Do not check file dates; such a
10972 check is unreliable on sufficiently fast machines, and removing
10973 the check makes the code simpler and more reliable. Check for
10974 output and chmod failures.
10976 * doc/autoconf.texi (Special Shell Variables): Document
10977 the above.
10979 2001-10-31 Akim Demaille <akim@epita.fr>
10981 * tests/Makefile.am (atconfig): Remove this target, Automake
10982 handles it now.
10984 2001-10-31 Akim Demaille <akim@epita.fr>
10986 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10987 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10988 provided, while it is optional.
10989 * configure.ac: Adjust.
10991 2001-10-26 Paul Eggert <eggert@twinsun.com>
10993 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10994 lib/Autom4te/Struct.pm:
10995 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10996 with 5.005_02.
10998 * doc/autoconf.texi (Special Shell Variables): Document some
10999 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
11001 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11002 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
11003 eval $LINENO is not portable in practice.
11005 2001-10-24 Akim Demaille <akim@epita.fr>
11007 * lib/Autom4te/General.pm (backname): New.
11009 2001-10-24 Akim Demaille <akim@epita.fr>
11011 * m4/: Remove, merged into...
11012 * config/: here.
11014 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
11016 * doc/autoconf.texi (Shellology): Mention the problems with bash
11017 2.05's use of ANSI quoting in its `set' builtin.
11019 2001-10-22 Paul Eggert <eggert@twinsun.com>
11021 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
11022 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11023 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
11024 POSIX decided to standardize on the int flavor of strerror_r.
11025 Always do char* test, as there's no reason not to.
11026 Assign to a char* var, to catch strerror_r that returns int*.
11028 * doc/autoconf.texi (Particular Functions):
11029 Document the above changes. Also, document the fact that
11030 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
11032 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
11034 2001-10-20 Akim Demaille <akim@epita.fr>
11036 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
11037 the executable was missing from the log.
11039 2001-10-20 Akim Demaille <akim@epita.fr>
11041 * lib/Autom4te/General.pm (&update_file): If destination is
11042 unchanged, remove the source.
11043 (&up_to_date_p): Don't be verbose, be debug.
11044 * bin/autoreconf.in: No longer support --m4dir.
11045 (&autoreconf): Display the full path of the configure.ac we are
11046 studying.
11047 Trace it only once.
11048 Be sure to honor --force with gettextize.
11049 Always run aclocal.
11050 * doc/autoconf.texi: Adjust.
11052 2001-10-20 Akim Demaille <akim@epita.fr>
11054 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
11055 Remove, dead.
11056 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
11057 `intl' is already present, as it refuses unless --force.
11058 (&parse_args): Use -I, --include instead of the old Autoconf
11059 options.
11060 ($localdir, $autoconf_dir): Remove.
11061 (@include): New.
11062 (&maybe_autoreconf): New, to preserve $_ for File::Find.
11064 2001-10-19 Jens Petersen <petersen@redhat.com>
11066 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

11069 2001-10-19 Akim Demaille <akim@epita.fr>
11071 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
11072 file in @configure_input@.
11073 Don't mention `automatically' in addition to `generated'.
11074 * tests/torture.at (#define header templates): Adjust.
11076 2001-10-19 Akim Demaille <akim@epita.fr>
11078 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
11079 comment, explain how to install automatic mode selection.
11080 From Russ Allbery.
11082 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
11084 * bin/autoreconf.in (autoreconf): Display the path to the
11085 configure.ac being studied.
11087 2001-10-18 Paul Eggert <eggert@twinsun.com>
11089 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
11090 long, to work around a bug in the HP C compiler version HP92453-01
11091 B.11.11.23709.GP.
11093 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
11094 (AS_BASENAME_EXPR): New macro.
11095 (AS_BASENAME_SED): Do not assume GNU sed semantics.
11096 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
11097 and fall back on 'sed' only if the other two fail. This makes
11098 AS_BASENAME act more like AS_DIRNAME.
11099 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
11100 contains white space.
11101 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
11102 Use AS_DIRNAME, since I think it's now DOS-friendly.
11103 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
11104 Allow "dirname //FOO" to return either / or //, as POSIX allows
11105 either behavior.
11107 2001-10-10 Akim Demaille <akim@epita.fr>
11109 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
11110 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
11111 From Eric Sharkey.
11113 2001-10-10 Akim Demaille <akim@epita.fr>
11115 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
11116 m4_define, since...
11117 (_AS_ECHO_N): AS_REQUIREs it.
11119 2001-10-10 Akim Demaille <akim@epita.fr>
11121 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
11122 (AC_INCLUDES_DEFAULT): Move to...
11123 * lib/autoconf/headers.m4: here.
11124 * lib/autoconf/types.m4: Comment changes.
11125 * doc/autoconf.texi: Specify where the default includes are used
11126 in the macro prototypes.
11128 2001-10-09 Akim Demaille <akim@epita.fr>
11130 * lib/autoconf/autoconf.m4 (m4_patsubst, m4_regexp): New
11131 transition code.
11133 2001-10-08 Akim Demaille <akim@epita.fr>
11135 * bin/autoreconf.in (&autoreconf): Remove debugging code.

11336 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

11370 * tests/fortran.at (GNU Fortran 77): there.
11371 * doc/autoconf.texi (autoconf Invocation): Fix the example:
11372 AC_TRY_RUN is about compilation, not shell commands.

11381 enough.

11432 * doc/autoconf.texi (Common Shell Constructs): Rename as...

11576 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check

11587 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
11588 `{}'.
11589 * lib/autotest/general.m4 (AT_INIT): Adjust.
11591 2001-09-18 Paul Wagland <paul@wagland.net>
11593 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11594 correctly.
11595 Add test for AS_BASENAME.
11596 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11597 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11598 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11599 * tests/base.at: Fixed the expected responses. The old ones were
11600 one line out...
11601 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11602 the documentation claims it should (and how it behaved in 2.13).
11604 2001-09-18 Akim Demaille <akim@epita.fr>
11606 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11607 the AC_CONFIG_COMMANDS invocation.
11608 This also solves the name clash problems.
11609 Don't set the package's ID.
11610 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11611 No longer to be shipped.
11612 (version.in): Remove.
11613 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11614 * lib/autoconf/status.m4: Adjust.
11615 Use `m4_PACKAGE_STRING'.
11616 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11617 the only optional argument is the name of the test suite.
11618 Expect `package.m4' to define the package signature.
11619 * lib/autom4te.in (Autotest): Add `package.m4?'.
11620 * tests/Makefile.am (package.m4): New.
11621 * tests/suite.at: ifnames is a victim.
11623 2001-09-18 Akim Demaille <akim@epita.fr>
11625 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11626 AC_LIBSOURCE, AC_CONFIG_FILES.
11627 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11628 program version string doesn't match the package's.
11629 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11630 after `(cached)'.
11632 2001-09-17 Paul Eggert <eggert@twinsun.com>
11634 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11635 Allow expression to return any value that can fit into unsigned long
11636 (not int, as before). Check for output errors.
11638 2001-09-17 Bruno Haible <haible@ilog.fr>
11640 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11641 Always include <stdio.h> and <stdlib.h>. Evaluate
11642 the expression in an extra function before these includes. Call
11643 fprintf "%d" only after ensuring the argument is of type 'int'.
11644 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11646 2001-09-17 Paul Eggert <eggert@twinsun.com>
11648 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11649 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11650 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11651 when they don't exist.
11653 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11654 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11655 need it.
11657 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11658 version with the version used by fileutils 4.1, except use
11659 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11660 we don't need it.
11662 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11664 2001-09-13 Akim Demaille <akim@epita.fr>
11666 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11667 _first_.
11668 Reported by Gerrit P. Haase.
11670 2001-09-13 Akim Demaille <akim@epita.fr>
11672 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
11673 m4_defn'ing is valid.

11691 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
11692 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
11693 AT_tests_all for consistency.
11694 Set at_victims.
11695 (AT_VICTIMS): Similar to AT_KEYWORDS.
11696 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
11698 2001-09-13 Akim Demaille <akim@epita.fr>
11700 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
11702 2001-09-13 Akim Demaille <akim@epita.fr>
11704 * lib/autotest/general.m4 (AT_INIT): Create and remove
11705 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11706 test suites can cohabit.
11708 2001-09-13 Akim Demaille <akim@epita.fr>
11710 * tests/mktests.sh: Don't output banners for empty test files.
11712 2001-09-13 Akim Demaille <akim@epita.fr>

11756 (m4_list_append): Remove.
11758 Spread a few keywords in the Autoconf test suite.
11760 2001-09-10 Akim Demaille <akim@epita.fr>
11762 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

11765 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

11778 2001-09-07 Akim Demaille <akim@epita.fr>

11795 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,

11798 Adjust PATH computation.
11799 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

11816 2001-09-05 Akim Demaille <akim@epita.fr>
11818 Be ready to handle filenames as stupid as `dnl.at', for if even
11819 the maintainer is dumb enough to do that...
11821 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11822 excellence in M4 quotation: consider `__file__' is active.
11824 And BTW, when invoking m4, pass the --include in the right order:
11825 the wrong one.
11827 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
11828 4m.
11830 2001-09-05 Akim Demaille <akim@epita.fr>
11832 * lib/Autom4te/XFile.pm: New lib file.
11833 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,

11836 2001-09-05 Akim Demaille <akim@epita.fr>
11838 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

11852 CVS GNU M4 doesn't like `undefine(undefined)'.
11854 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
11855 New, extracted from main.
11856 Use IO::File wherever possible.
11857 (input.m4): Be constant, use -I instead of hard coding $tmp.
11858 Therefore be a quoted heredoc.
11859 Don't invoke `_au_disable', since ac was not loaded, but just
11860 `unm4.m4'.
11862 2001-08-31 Akim Demaille <akim@epita.fr>
11864 Version 2.52d.
11866 2001-08-31 Akim Demaille <akim@epita.fr>

11885 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11887 2001-08-31 Akim Demaille <akim@epita.fr>
11889 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11890 (testsuite Scripts): There is no such thing as `atconfig.in'.
11891 And actually one diagram is missing: test suite runtime.
11893 2001-08-31 Akim Demaille <akim@epita.fr>
11895 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11896 inverse order.
11898 2001-08-31 Akim Demaille <akim@epita.fr>
11900 * bin/autoupdate.in (@include): `installcheck' revealed the path
11901 to m4sugar was lacking!
11903 2001-08-31 Akim Demaille <akim@epita.fr>
11905 * man/Makefile.am (.x.1): We really have to pass
11906 autom4te_perllibdir.
11908 2001-08-31 Akim Demaille <akim@epita.fr>
11910 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11911 debug scripts, in particular passing explicitly listed tests to
11912 run is stupid.
11914 2001-08-31 Akim Demaille <akim@epita.fr>
11916 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11917 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11918 Use directly autom4te, not autoconf.
11919 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
11921 2001-08-31 Akim Demaille <akim@epita.fr>
11923 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

11932 * bin/autom4te.in (&parse_args): Die on unknown languages.
11933 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
11934 need for autoconf.
11935 Promote --include over --macrodir and other obsolete options.
11937 2001-08-31 Akim Demaille <akim@epita.fr>
11939 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

11941 * bin/autom4te.in ($autoconf): Pass --force.
11942 `print $out' doesn't print `$_' but `$out'.
11943 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11944 (autoheader): Pass --force since the test suite goes too fast for
11945 the time stamps.
11946 Adjust to the new autoheader messages.
11948 2001-08-31 Akim Demaille <akim@epita.fr>
11950 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11951 Check the completeness of the #template.
11952 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
11953 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
11954 invocation.

11958 * lib/Autom4te/General.pm (&find_file, &update_file): New.
11959 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11960 Drop AC_MACRODIR dead for real.
11961 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11962 `autoheader: `config.hin' is created'.
11963 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11965 2001-08-31 Akim Demaille <akim@epita.fr>
11967 * bin/autoheader.in: Rewrite in Perl.
11968 * tests/autoheader: Adjust.
11970 2001-08-31 Akim Demaille <akim@epita.fr>
11972 * bin/autoconf.in (--include, -I): New option.
11973 Map --localdir, --autoconf-dir onto it.
11974 Forward autom4te's options instead of interpreting them.
11975 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11976 There is no such envvar since the inception of autom4te.cfg.
11977 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11978 * bin/autoupdate.in: Adjust, and perform more control.
11979 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11980 * tests/autoconf: Dittowise.
11982 2001-08-31 Akim Demaille <akim@epita.fr>
11984 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11985 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11986 optionally `FILE'.
11987 Use -e, not -f, since /dev/null for instance is OK.
11988 (&parse_args): Adjust.
11989 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11991 2001-08-31 Akim Demaille <akim@epita.fr>
11993 * configure.ac: Also find tested executables in bin.
11994 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11995 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11996 installed peer executables, only PATH is allowed to resolve it.
11997 Pass `autoconf_dir' via options, not via invisible envvars.
11998 * lib/Autom4te/General.pm (&find_peer): Remove.
11999 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
12000 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
12001 * man/Makefile.am: Let help2man rely on PATH instead of trying to
12002 find the executables for it.
12003 * tests/Makefile.am: Major cleanup. Too lazy to document...
12004 * tests/atlocal.in: Remove all the obscure envvar manipulations.
12005 We only need PERL.
12006 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
12007 indeed related to running the test suite, while passing
12008 --autoconf-dir and others is related to running non installed
12009 Autoconf executables. So don't do that, leave it to...
12010 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
12011 * tests/autoscan: New.
12012 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
12013 refer to library files: rely on --language.
12015 2001-08-29 Akim Demaille <akim@epita.fr>
12017 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
12018 s/--set/--language/.
12020 2001-08-29 Akim Demaille <akim@epita.fr>
12022 * doc/autoconf.texi: Strip the @nodes.
12023 Suggested by Paul Eggert.
12024 (Initializing configure): Typo.
12026 2001-08-29 Akim Demaille <akim@epita.fr>
12028 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.

12209 the name of the directory they're in, instead of the filename,

12501 2001-08-15 Akim Demaille <akim@epita.fr>
12503 * bin/autom4te.in (@m4_warning): New.
12504 (&handle_m4): Use it.
12505 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12506 warnings are issued at each run.
12507 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12508 is in the src tree.
12510 2001-08-15 Akim Demaille <akim@epita.fr>
12512 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
12513 don't waste time running `autoupdate --version' works.
12514 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
12516 2001-08-13 Akim Demaille <akim@epita.fr>

12575 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12577 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12578 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12579 * doc/autoconf.texi (C Compiler Characteristics): Update
12580 documentation for AC_C_BIGENDIAN.
12582 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12584 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12585 magic values from an object file when cross-compiling.
12586 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12588 2001-08-10 Akim Demaille <akim@epita.fr>
12590 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12591 effects.
12592 Suggested by Russ Allbery.
12594 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12596 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12597 current $prefix to the sub-configures.
12599 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12601 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12602 extension (needed on BeOS). Reported by Guido van Rossum.
12604 2001-08-09 Akim Demaille <akim@epita.fr>
12606 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12608 2001-08-07 Akim Demaille <akim@epita.fr>
12610 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12611 removed.
12612 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12613 No need to remove the files before and after the each test, before
12614 each test and at the end of the suite is enough.
12615 Display only the children `times', not the shell's.
12616 If the test failed or was skipped, at-times is not available.
12618 2001-08-07 Akim Demaille <akim@epita.fr>
12620 Always produce testsuite.log, including when there are no
12621 failures. This helps getting information on skipped tests, and
12622 duration of the tests. Err, implement the latter btw.
12624 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12625 Dump information on the first run of each test.
12626 (AT_CLEANUP): Create `at-times' containing the duration of the
12627 test group.
12629 2001-08-07 Akim Demaille <akim@epita.fr>
12631 The use of `dumpstat' revealed that `len' was used although it
12632 should not. m4_text_wrap was using it, but in the Autoconf world
12633 where it is legal. Hence (i) test M4sh in its own world, not
12634 Autoconf's, and (ii), ahem, fix the bug :)
12636 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12637 does not like `' instead of [].
12638 (AT_INIT): Forbid `^_?AT_'.
12639 And don't output such tokens.
12640 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12641 `script.as', and `autom4te.cache'.
12642 Remove `empty' and `macro' which are no longer used.
12643 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12644 * tests/m4sugar.at: Use it.
12645 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12647 2001-08-07 Akim Demaille <akim@epita.fr>
12649 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12651 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12653 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12655 2001-08-04 Akim Demaille <akim@epita.fr>
12657 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12658 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12659 AC_TRY_LINK.
12660 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12661 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12662 (AC_F77_MAIN): Likewise.
12664 2001-08-04 Akim Demaille <akim@epita.fr>
12666 Don't rely on M4sugar outputting the patterns in files, since we
12667 might process the output _without_ running m4, hence without these
12668 files.
12670 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12671 * bin/autom4te.in (@Request::includes): Remove, unused.
12672 (@Request::source): Rename as...
12673 (@Request::input): this.
12674 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12675 (&handle_output): Fetch the patterns from the traces.
12676 `$forbidden' and `$allowed' are constant: use m//o.
12677 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12678 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12680 2001-08-04 Akim Demaille <akim@epita.fr>
12682 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12683 autoconf', i.e., in addition to caching traces, cache the output.
12685 * bin/autom4te.in (Request::cache): Rename as...
12686 (Request::id): this.
12687 ($cache, $icache, $tcache, $ocache): New.
12688 (&handle_m4): Save M4 output in the cache instead of $tmp.
12689 (&handle_output): Adjust.
12690 (&up_to_date_p): Check that the output cache is up to date too.
12691 (top level): Run `&handle_m4' iff force or the cache is invalid.
12692 Run `&handle_output' if the output cache is more recent.
12694 2001-08-04 Akim Demaille <akim@epita.fr>
12696 * bin/autom4te.in ($force): New.
12697 (&parse_args, &print_usage): -f, --force is a new option.
12698 (&handle_output): CPP directives might have spaces after `#'.
12699 (&parse_args): The first file only can be frozen.
12701 2001-08-04 Akim Demaille <akim@epita.fr>
12703 Don't let autom4te compute the `include' traces several times:
12704 first check that the trace cache file is up to date, and then
12705 compare its timestamp with that of the output.
12707 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12708 the preamble. Don't require 5.005 as Autom4te::General does it,
12709 and better yet (use `use', not `require'!).
12710 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12711 Class::Struct as Autom4te::Struct.
12712 * lib/Autom4te/General.pm (File::stat): Use it.
12713 (&mtime): New, export it.
12714 * bin/autom4te.in: Use it.
12715 Declare `$req' is invalid if it is outdated.
12716 Don't declare it valid before saving it if something went wrong.
12718 2001-08-04 Akim Demaille <akim@epita.fr>
12720 Autom4te shall not encode Autoconf data, and preselecting traces
12721 must be proposed to the users.
12723 * bin/autom4te.in (@required_trace): Remove.
12724 (@preselect): New.
12725 (&parse_args, &print_usage): -p, --preselect is a new option.
12726 (&up_to_date_p): Adjust.
12727 * bin/autoconf.in: Preselect some Autoconf macros.
12729 2001-08-04 Akim Demaille <akim@epita.fr>
12731 * tests/tools.at (autoconf --trace: user macros): Check traces on
12732 macros invoked without arguments, and macros invoked with multiple
12733 lines arguments.
12735 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
12737 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
12738 arguments.
12740 2001-08-03 Akim Demaille <akim@epita.fr>
12742 * bin/autoconf.in ($@): Work around the usual sh bug.
12743 From Nicolas Joly.
12745 2001-08-03 Akim Demaille <akim@epita.fr>
12747 Clean up the handling of the M4 builtins tracing exception.
12749 * bin/autom4te.in (Request::request): Don't complete M4 builtins
12750 trace requests.
12751 (@m4_builtins): Rename as...
12752 (@m4_builtin): this.
12753 (%m4_builtin_alternate_name): New.
12754 (&parse_args): Complete the trace requests with alternate names.
12755 (&handle_traces): Hence no longer do it here.
12756 (&trace_requests): Remove, unused.
12758 2001-08-03 Akim Demaille <akim@epita.fr>
12760 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
12761 m4_if, and m4_wrap.
12763 2001-08-03 Akim Demaille <akim@epita.fr>
12765 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
12766 (m4_divert_pop): Dump the whole diversion stack when a diversion
12767 mismatch happens.
12768 * bin/autom4te.in (&handle_output): Remember of the first
12769 occurrence of a possibly undefined macro, not the last.
12770 Complain about the possibly undefined macros in the same order as
12771 the appear in the output.
12772 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
12773 * tests/tools.at (autoconf: forbidden tokens, basic)
12774 (autoconf: forbidden tokens, exceptions): No longer sort
12775 autoconf's stderr, as it is now deterministic.
12776 Check that `dnl' is caught.
12778 2001-08-01 Akim Demaille <akim@epita.fr>
12780 * configure.ac: Bump to 2.52c.
12782 2001-08-01 Akim Demaille <akim@epita.fr>
12784 Version 2.52b.

12792 2001-08-01 Akim Demaille <akim@epita.fr>
12794 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
12795 `die'.
12796 (&END): New.
12797 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
12798 `END', as `Autom4te::General::END' will be triggered.
12799 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
12800 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

13235 cross-language link tests can be performed successfully.
13236 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
13237 after $LIBS, for consistency; this should be the general rule since

13244 at-stdout and at-stderr instead of removing the newline
13245 from the echo output, which is not guaranteed to work.

13313 * doc/autoconf.texi (Redefined M4 Macros): New.
13315 2001-06-23 Akim Demaille <akim@epita.fr>

13356 ./configure --program-suffix=foo produces `transform=s,$$,foo,;',
13357 but some sed choke on multiple `;', and other tools (e.g.,
13358 Automake), include the separator themselves.
13360 * acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
