25 * doc/autoconf.texi (Special Shell Variables): Warn about FPATH.
26 (Macro Names, Defining Directories): Don't mention PATH as a name
27 for a fully qualified file name, as this usage violates the GNU
28 coding standards and we shouldn't recommend it.
30 * lib/autotest/general.m4 (AT_INIT): Don't set PATH to the empty
31 string and then assume shell builtins like "test" will work.

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

214 * doc/autoconf.texi (Generic Types): Document the restrictions
215 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
216 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
217 with objects too. Document the restrictions on its use.
218 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
219 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
220 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
221 works but the latter doesn't, then it's a valid type.
222 This lets people use function types and so forth.
223 For C++ there doesn't seem to be a simple solution, so leave it alone.
224 (AC_CHECK_SIZEOF): Allow argument to be a variable.
225 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
226 AC_CHECK_TYPE; that wasn't documented or necessary.
228 2007-04-11 Stepan Kasal <kasal@ucw.cz>
230 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

283 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
284 (Limitations of Usual Tools): Also list \< and \>, and mention that
285 HP-UX's grep, like the one from Solaris, does not support that syntax.
287 2007-03-09 Stepan Kasal <kasal@ucw.cz>
289 * doc/autoconf.texi (Specifying Names): `--host' does not

396 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
397 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its

423 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
424 early on the reader side, drop stderr of the input to avoid
425 `broken pipe' error output; this may happen even with shell
426 builtin `echo' of some bash versions. Reports by Ian Macdonald
427 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.

442 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
443 * doc/autoconf.texi (Signed Overflow Examples): Give more
444 discussion about the allow_superuser_privileges example,
445 and change it a bit to make things clearer.
446 (Optimization and Wraparound): Clarify whether the compiler
447 will generate an infinite loop for the example derived from
448 Autoconf's mktime test.
449 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
450 Also, clarify unsigned multiplication overflow.
452 2007-01-04 Eric Blake <ebb9@byu.net>
454 * bin/Makefile.am (RELEASE_YEAR): New macro.
455 (edit): Use it to supply correct copyright year to scripts.
456 * bin/autoconf.as (version): Use it.
457 * bin/autoheader.in ($version): Likewise.
458 * bin/autom4te.in ($version): Likewise.
459 * bin/autoreconf.in ($version): Likewise.
460 * bin/autoscan.in ($version): Likewise.

462 * bin/ifnames.in ($version): Likewise.
464 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
466 * doc/autoconf.texi (Integer Overflow): Revised based on today's
467 feedback. The most important changes document what happens when
468 you convert an out-of-range value to a signed integer type, and
469 say that (sum < a) != (b < 0) reliably detects overflow when sum =
472 * doc/autoconf.texi (Integer Overflow): Greatly expand and
473 rewrite, taking notions from the recent discussion on the gcc and
474 autoconf mailing lists; please see
475 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
476 and follow the many links.
477 (Integer Overflow Basics, Signed Overflow Examples):
478 (Optimization and Wraparound, Signed Overflow Advice):
479 (Signed Integer Division): New sections.
481 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
483 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
484 preprocessor macro arguments in traced name.
485 * doc/autoconf.texi (Defining symbols): Document longstanding
486 support for AC_DEFINE-ing macros with arguments, and document
487 behavior when the same variable has multiple AC_DEFINEs.
488 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
489 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
490 macros directly, giving much shorter and simpler code.
492 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
494 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
495 space before "$ac_configure_args" to prevent a 'config.status
496 --recheck' failure if ac_configure_args doesn't contain a leading
497 space. This works around a problem with the XEmacs configure.ac,
498 which uses the (undocumented) ac_configure_args variable
499 inconsistently with Autoconf.
501 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
503 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
504 Include <limits.h>, and use its INT_MAX to rewrite the
505 j loop so that it does not overflow 'int'. Problem reported by
507 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
508 Play it safe by shifting left by 1 rather than multiplying by 2,
509 as GCC is less likely to optimize this away when the value
510 is signed (when it assumes overflow leads to undefined behavior).
511 Also, don't assume time_t uses two's complement.
513 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
515 * tests/torture.at (Substitute a 2000-byte string): Avoid using
516 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
517 dumps core on it. Report by Tim Rice.
519 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
521 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
522 --disable-option-checking to --help output even when
523 AC_PRESERVE_HELP_ORDER is not used.
524 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
525 --with argument, rather than argument with [-.] replaced by
527 * NEWS: Fix typo in previous change; the news was in the
530 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
532 * NEWS: Warnings are now generated by default for unknown
533 --enable-* and --with-* options.
534 * doc/autoconf.texi (Option Checking): Renamed from
535 (Configure Option Checking). Tighten up the wording a bit.
536 (External Software, Package Options): Cross-reference to Option
537 Checking, and use this to shorten our section.
538 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
539 "$x" to test "x$foo" != x.
540 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
541 Don't warn if $enable_option_checking is "no".
542 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
543 ac_unrecognized_opts to the empty string.
544 Don't echo the unrecognized opts, as this might mishandle
545 backslashes or leading -.
546 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
547 usage next to the other --disable-FEATURE options in the
550 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
552 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
553 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
554 Print warning for unrecognized --with and --enable options
555 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
556 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
557 Disable option checking when subdirs are configured.
558 (AC_OUTPUT): If warnings are enabled, print warning about
559 unrecognized --with and --enable options at the end of
560 the configure output (as well as at the beginning).
561 * doc/autoconf.texi (Option Checking): New node.
562 Document new option warning functionality.
564 2006-12-16 Eric Blake <ebb9@byu.net>
566 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
567 * NEWS: Start news for current version.
569 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
571 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
572 Define HAVE_GETMNTENT to 1, not to the empty string.
573 Problem originally reported by Jochen Friedrich in
574 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
576 This change prompted by a problem report by Andrey Simonenko in
577 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
578 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
579 object-like macros only, in the traditional portable character
581 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
582 Warn about attempts to define things that are not identifiers.
583 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
584 awful hack that AC_DEFINEd macro names containing parentheses.
586 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
588 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
589 too drastic, even if Texinfo in theory requires it for info mode.
591 (config.status Invocation): Renamed back from Recreating a
593 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
594 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
596 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
598 * NEWS: Version 2.61a.
600 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
601 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
603 * NEWS: Document changes with echo and printf, and the lack
604 of limits on the total size of multi-line values of substituted
605 variables, and the AC_FUNC_FSEEKO fix.
607 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
609 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
610 Writing configure.ac.
611 (Autoconf Input Layout): Renamed from configure.ac Layout.
612 (Recreating a Configuration): Renamed from config.status Invocation.
613 (Obsolete Recreation): Renamed from Obsolete config.status Use.
614 (acconfig Header): Renamed from acconfig.h.
615 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
616 (Writing Testsuites): Renamed from Writing testsuite.at.
617 (Autom4te Cache): Renamed from autom4te.cache.
619 * BUGS: Remove mention of VPATH problem, since it's now documented
620 not to be a bug in the Autoconf build procedure itself, but rather
621 a problem with the proprietary `make' programs.
623 * doc/autoconf.texi (Build Directories): Add a cross reference
626 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
627 * doc/standards.texi: Sync from gnulib.
629 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
630 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
631 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
632 generated automatically.
634 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
636 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
637 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
638 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
640 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
642 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
643 `CEOF$ac_eof' special marker, the awk script cannot contain a
644 line matching `^CEOF', so this is not needed any more.
645 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
646 special marker in the test.
648 2006-12-06 Stepan Kasal <kasal@ucw.cz>
650 * tests/tools.at (autom4te preselections): Use `find -newer';
651 remove one of the sleeps.
653 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
654 more readable, using ...
655 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
657 * doc/autoconf.texi (autoheader Invocation): Do not double-
658 quote the parameter of `AH_BOTTOM' in the example.
660 2006-12-05 Stepan Kasal <kasal@ucw.cz>
662 * doc/autoconf.texi (Configuration Headers): Remove the
663 example with multiple input files.
664 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
665 multiple input files.
667 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
669 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
670 creating the awk substitution script, handle one input line at a
671 time, so that the maximum length of a substituted (multi-line)
672 value is not limited by the size of the sed pattern space.
673 The trade-off is a slightly repetitive sed script.
674 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
675 can only have up to 7 characters, due to Solaris 10 /bin/sed.
676 * tests/torture.at (Substitute a 2000-byte string): Increase the
677 test with several long lines, they should not be caught by sed
680 * tests/tools.at (autom4te preselections): New test, to flag
681 entries missing from autom4te.cfg.
682 Report by David Byron <dbyron@hheld.com>.
684 * tests/torture.at (Substitute a 2000-byte string): Actually use
685 AC_PROG_AWK, so the last change works as intended.
686 (Substitute and define special characters): Likewise.
687 (Substitute a newline): Likewise.
689 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
690 instead of `awk' consistently.
691 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
692 * tests/torture.at (Torturing config.status): Test both the
693 result of AC_PROG_AWK and plain awk.
694 (Substitute a 2000-byte string): Likewise.
695 (Substitute and define special characters): Likewise.
696 (Substitute a newline): Likewise.
698 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
700 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
701 can be assigned to a function pointer. Problem reported by
702 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
703 part of a patch by Ralf Wildenhues in that same bug report.
705 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
707 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
708 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
710 2006-12-01 Eric Blake <ebb9@byu.net>
712 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
713 cross-compiling from cygwin to mingw.
714 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
715 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
716 to lib/autoconf/c.m4.
718 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
720 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
721 string for more reliable failure. Wrap the entire test that
722 causes the broken Solaris printf to dump core, in a subshell,
723 so the segmentation fault message is reliably suppressed.
724 Fix shell expansion errors by using /usr/ucb/echo always;
725 avoid an error on systems without it by another subshell.
726 Avoid m4 expansion of `$1'. Set the zeroth argument of the
727 subshell-$as_echo to `as_echo', for better error message.
729 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
731 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
732 `BASH_SOURCE' contain a newline, set them to empty, as they may
735 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
737 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
738 years and is too hard to maintain now. The last straw was
739 reported by Jerker Baeck in
740 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
741 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
742 * doc/autoconf.texi (Particular Functions): Move
743 AC_FUNC_SETVBUF_REVERSED from here...
744 (Obsolete Macros): ... to here. Say that it does nothing now.
745 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
746 Turn into (almost) a no-op.
748 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
750 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
751 These macros are obsolescent and new applications shouldn't need them.
752 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
753 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
754 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):

759 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
761 * doc/autoconf.texi (Setting Output Variables): Mention that
762 @VAR1@VAR2 has unspecified behavior. Problem reported by
764 * NEWS: Mention this.
766 * Makefile.am: Put only a single '#' into the copyright notice,
767 so that it's also present in the output file. Standardize wording
768 in makefile copyright notices to match GNU coding standards.
769 * bin/Makefile.am: Likewise.
770 * doc/Makefile.am: Likewise.
771 * lib/Makefile.am: Likewise.

779 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
782 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
784 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
785 in the sed script that mangles the awk script: delete up to the
786 first exclamation mark only.
787 * tests/torture.at (Substitute and define special characters):
790 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
792 Rewrite config files generation: avoid quadratic growth in
793 the number of substituted variables by using awk instead of sed
794 for the bulk of the substitutions.
795 * NEWS: Mention this.
796 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
797 forbidden in the output (and thus input) file.
798 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
799 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
800 generate just one large awk script for substitutions,
801 eliminating much of the earlier complexity, while adding some
802 new complexity. Only expand the substitution templates at
803 configure time, for smaller configure script size. If
804 _AC_SUBST_FILES are used, test 'awk' for working getline support
805 at config.status time. If absent, interpolate through the
806 shell. The awk script was written with much help
807 from Paolo Bonzini and Paul Eggert.
808 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
809 (_AC_SED_FRAG_NUM): Likewise.
810 (_AC_SUBST_CMDS): Renamed from...
811 (_AC_SED_CMDS): ...this.
812 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
813 * tests/torture.at (Substitute a 2000-byte string): Also
814 substitute a line with 1000 words, and a variable with several
816 (Substitute and define special characters): Test awk special
817 characters, and put substitution input strings `@foo@' in the
818 output, to test that no recursion happens; test several other
819 combinations from Paolo Bonzini.
821 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
823 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
824 that replaced echo with AS_ECHO where this wasn't necessary.
825 Problem reportd by Ralf Wildenhues.
826 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
827 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
828 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
830 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
832 * lib/freeze.mk (GREP): Removed, no need to initialize this.
834 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
836 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
837 that traditional Awk lacks 3-arg "split". It has it.
838 Mention that FS must be a single character, and a few other
839 99-byte limits of traditional Awk.
840 Mention that if (i in a) doesn't work with traditional Awk.
842 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
844 * tests/autotest.at (BSx641-newline in command):
845 (BS-BS-newline in command, BSx640-newline in command):
846 (Newline-CODE-BS-newline in command):
847 (Single-quote-BS-newline in command):
848 (Single-quote-newline-BS-newline in command):
849 Use printf '%s\n' instead of echo, for portability to hosts
850 where echo interprets backslashes. This will break on hosts
851 that lack printf, but for now let's assume all such hosts
852 are dead (if not, we should get reports of test failures).
854 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
856 'echo' has some portability problems, when given a first argument
857 with a leading '-', or when given any argument containing '\'.
858 Avoid using 'echo' in these cases.
859 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
860 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
861 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
862 * lib/autotest/general.m4 (AT_INIT): Likewise.

864 argument might be unportable.

883 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
884 * bin/autoconf.as: Redo verbose flag implementation, as the old
885 scheme wouldn't work with AS_ECHO.
886 * lib/autotest/general.m4 (AT_INIT): Likewise.
887 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
888 Don't use ECHO_T, since ECHO_N is now reliable.
889 * lib/autotest/general.m4 (AT_INIT): Likewise.
890 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
891 rather than using a here-document to put the script into a file.
892 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
894 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
895 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
896 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
897 bug, but we might as well stop using ECHO_N and ECHO_C internally.
898 * lib/autotest/general.m4 (AT_SETUP): Likewise.
899 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
900 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
901 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
902 operand, as AS_ECHO requires. Avoid double file name expansion.
903 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
904 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
905 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
906 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
907 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
908 Double-quote strings that would otherwise contain M4 comments.
909 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
911 * configure.ac (AC_INIT): Bump to 2.61a.
914 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
918 * configure.ac (AC_INIT): Bump to 2.61.
921 * tests/autotest.at (Macro with backslash in a test title):
922 Comment out for now, as this tests neither fails nor passes
923 reliably. Problem reported by Ralf Wildenhues.
925 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
927 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
928 in previous change, which caused test failures.
930 2006-11-16 Stepan Kasal <kasal@ucw.cz>
932 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
933 code for --enable, --disable, --with, and --without to...
934 (_AC_INIT_PARSE_ENABLE): ... a new macro.
935 * doc/autoconf.texi (Package Options):
936 * NEWS: Document that AC_ARG_ENABLE allows dots, too.

965 Import this change from gnustandards via gnulib:
967 2006-11-15 Karl Berry <karl@gnu.org>
969 * standards.texi: core -> memory, throughout.
970 (CPU Portability): show correct example of calling write
971 on a char value; thanks to Paul Eggert for the code.
972 Both of these suggestions from Eugene Y. Vasserman.
975 Import these changes from texinfo via gnulib:

1015 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
1016 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.

1048 Single-quote in a test title,
1049 Double-quote in a test title): Don't expect failure anymore.
1050 (Backslash in a test title): Put a non-whitespace character after the
1051 backslash so that Bourne shells might actually see it as an escape

1060 Macro with double-quote in a test title,
1061 Macro with backslash in a test title): New tests expected to fail.
1062 * tests/torture.at (#define header templates): M4-quote this title in
1063 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
1064 The visible effect was a stray [] in the testsuite output.
1066 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1068 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
1069 `trap ... 0' inside a function, for AIX sh.
1071 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1073 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1074 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1075 5363) simply issues a warning when dividing by zero at compile
1076 time. Problem reported by Elias Pipping.
1078 2006-10-26 Eric Blake <ebb9@byu.net>
1081 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1082 show effect on macros that expand with commas.

1110 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1111 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1112 reported by Nelson H. F. Beebe for Coreutils 6.4.
1114 * tests/tools.at (autoconf --trace: user macros): Remove test
1115 for tracing multiline macros, since m4 1.4.7a uses a different
1116 way to number lines. Problem reported by Ralf Wildenhues.

1146 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1147 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

1192 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1194 (Imported from Automake.)
1195 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1196 which incorrectly sets the mode of an existing destination
1197 directory. In some cases the unpatched install-sh could do the
1198 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1199 system. We hope this is rare in practice, but it's clearly worth
1200 fixing. Problem reported by Alex Unleashed in
1201 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1202 Also, don't bother to check for -m bugs unless we're using -m;
1203 suggested by Stepan Kasal.

1249 2006-10-13 Stepan Kasal <kasal@ucw.cz>
1251 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1252 added to the template can get mangled.
1254 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1256 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1257 include the default headers, and redefine obstack_chunk_alloc
1258 and obstack_chunk_free. Fixes false failure with glibc.

1279 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1280 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1281 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1282 Use a better substitute, by inspecting the output of "ls"
1283 rather than just using ":".
1284 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1285 rather than AS_EXECUTABLE_P, since we needn't worry about
1286 non-regular files here.
1288 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1289 due to configuration hassles with this. See Tonya Underwood's report
1290 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

1313 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1314 comment about ac_cpp_err; it was incorrect, and anyway
1315 ac_cpp_err is being removed below.
1316 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1317 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1318 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1320 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1321 with werror_flag and conftest.err and so forth. This is more
1322 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1323 and anyway the user shouldn't normally want to see this gorp logged.
1324 Problem reported by Ralf Wildenhues.
1325 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1326 empty, not 'no', since the rest of the code uses 'test -z'.

1330 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1331 Use a single call to AC_DO_TOKENS rather than multiple, for

1334 Problem reported by mwoehlke in
1335 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1337 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1338 than creating a file to use with test -x; this is much faster.
1340 2006-10-02 Bruno Haible <bruno@clisp.org>
1342 * lib/autom4te.in (Automake-preselections): Add
1343 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1345 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1347 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

1352 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

1354 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1355 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1356 still doesn't let the program compile.
1357 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1360 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1361 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1362 include it, without including anything else.
1363 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1365 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

1382 values. Problem reported by Ralf Wildenhues.

1474 too late, anyway. Problem reported by Stefan Seefeld.
1476 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
1477 7.1.4 /usr/bin/posix/sh described by Tim Rice in

1493 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1494 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1495 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now

1543 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
1544 except the first two arguments are reversed.
1545 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1546 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
1547 caches nor outputs a diagnostic. Suggested by Bruno Haible.

1593 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1595 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1596 didn't work if some values were cached but not others. Test for
1597 broken lex libraries like native ia64-hp-hpux11.22; see
1598 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1599 work around the problem by preferring an empty LEXLIB to -lfl or
1600 -ll. Let the user set LEXLIB='' to indicate no library needed.

1727 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1728 -Wundef -Werror". Problem reported by David Fang in
1729 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

1751 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1752 problems with arg script text that doesn't end in newline, and

1755 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1757 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

1789 less skeptical about "volatile", after discussion with
1790 Bruno Haible on bug-gnulib.
1791 (Limitations of Usual Tools): Warn about sed stripping
1792 leading white space from text. From Bruno Haible.

1801 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

1804 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1806 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

1819 under AC_C_VOLATILE.
1820 (Volatile Objects): Be a little less skeptical about what

1828 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1830 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1831 more globally, since the 2006-06-30 patch didn't suffice. Problem
1832 reported by Keith Marshall. Also, don't bother with builddir2,
1833 since it shouldn't be needed any more.
1835 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1837 * doc/autoconf.texi (Generic compiler characteristics):
1838 Document AC_COMPUTE_INT. Fix wrong statements on Default

1854 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1856 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1857 Require that long long int be at least 64 bits wide. C99 requires
1858 this and enough programs depend on it so we should check for it.
1859 Bruno Haible reports in
1860 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1861 that long long int is 32 bits wide with some nonstandard compilers.
1862 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1864 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1866 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1867 to a nonexistent file, so that we don't have to worry about
1868 a local site configuration that doesn't use /usr/local.
1869 Problem reported by Keith Marshall in
1870 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1872 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1874 * doc/autoconf.texi: Be more consistent about using @acronym with
1875 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1876 quite right (it talked about "OSF/Tru64", even though the
1877 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1878 and it even mentioned "OSF 4"!) and at this point there's little
1879 reason to talk about OSF any more, since it died in 1994.
1880 (Specific Compiler Characteristics): Simplify example of
1881 negative-size array.
1882 (File Descriptors): Reorder to make the text flow better.
1883 Remove joke about "appreciate the various levels"; I didn't get it.
1884 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1885 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1886 (File Descriptors, Limitations of Usual Tools):
1887 Tone down the advice against renaming or removing open files.
1888 (Limitations of Usual Tools): Add a new section, on 'rm'.
1890 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1892 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1893 -lXt in LIBS, idea from Karsten Hopp; this was due since
1896 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1897 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1898 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1899 (which belong to Xt, not X itself). See Debian bug 327655.
1901 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1926 to document the whole `datarootdir' business a bit better.
1928 * tests/torture.at (datarootdir workaround): Extend test.
1929 Prompted by report by Alexandre Julliard.
1931 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1933 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1934 when using default mode of IBM C 6 for AIX. Problem and two-line
1935 fix reported by Larry Jones.
1937 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1939 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1940 about literal '${datarootdir}' if a definition is found in the
1943 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1945 * NEWS: Use "M4" rather than "m4" when appropriate.
1946 Problem reported by Eric Blake.
1947 * doc/autoconf.texi: Likewise.
1948 Use @acronym around BSD, GCC, and GNU when appropriate.
1949 (Why GNU M4): Renamed from "Why GNU m4".
1950 (Redefined M4 Macros): Mention that Posix
1951 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1952 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1955 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1957 * bin/autom4te.in (handle_output): Do not forbid the empty
1959 * tests/tools.at (autoconf: the empty token): New test.
1961 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1963 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1964 calls, so that we do not care whether they are LIFO or FIFO;
1965 in the m4_wrap, do not check which diversion is the topmost
1966 one, just check that the stack is balanced at the end.
1967 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1968 base diversion forever--pop the previous diversion before
1969 opening the new one; consequently, remove the m4_wrap call.
1970 * lib/autotest/general.m4 (AT_INIT): Likewise.
1971 * tests/m4sugar.at: Do not use
1972 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1974 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1975 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1977 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1978 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1979 Rework example of m4wrap token-pasting trouble so that it doesn't
1980 care whether it's LIFO or FIFO.
1981 Fix some "contrary to"s that are awkward in English.
1983 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1985 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1986 to `yes' instead of `int$1_t' if the type is found, for more
1987 consistent configure output (where $1 is the number of bits).
1988 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1989 Suggested by Bruno Haible.
1991 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1992 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1993 with system headers. Report by Bruno Haible.
1995 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1997 * config/config.guess, config/config.sub: Sync from upstream.
1999 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2000 in order to avoid picking up an older installed frozen m4sh.m4f.
2001 Besides an outdated shell startup, this could have been created
2002 by an earlier M4 version with incompatible frozen file format.
2004 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2006 * README: Recommend m4 1.4.4 instead of 1.4.3..
2007 * doc/autoconf.texi: Likewise.
2008 (Special Chars in Names): Say that $(.FOO) is portable, as
2009 suggested by Stepan Kasal.
2010 (Installation Directory Variables, Build Directories):
2011 (Automatic Remaking, Subdirectories, Fortran Compiler):
2012 (Making testsuite Scripts, Defining Directories):
2013 Quote variable usages better.
2014 (Making testsuite Scripts): Add clean-local rule to makefile
2015 snippet, by Eric Blake.
2016 (Installation Directory Variables): Fix table item font.
2017 Reword slightly to clarify. Generalize advice about
2018 not using special characters to include all file-related
2019 vars, not just VPATH.
2020 (Special Chars in Variables): Warn about special characters in
2022 (Assignments): Clarify default-value example as suggested by
2024 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2025 (Special Shell Variables): Note leading ./ or ../, as suggested
2027 (Limitations of Builtins): Under cd, warn about CDPATH.
2028 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2031 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2033 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2034 `@var', for texi2html.
2035 (Systemology): Some more word wrapping, for DVI output.
2036 (autom4te Invocation): The short option for `--melt' is `-M',
2039 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2041 * doc/autoconf.texi: More formatting and English tweaks,
2042 many suggested by Ralf Wildenhues.
2043 Reword to avoid "@code{...}'s" and the like, since it's ugly
2044 with Emacs info mode. discontents -> woes.
2045 Put a few "will"s back. time stamp -> timestamp.
2046 side-effect -> side effect.
2048 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2050 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2051 Warn about $@ not persisting. Problem reported by Julien Danjou in
2052 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2053 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2054 Mention other special chars, too.
2056 2006-06-14 Eric Blake <ebb9@byu.net>
2058 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2060 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2062 * doc/autoconf.texi: Some systematic minor improvements, as
2063 follows. Use "makefile" when talking about makefiles
2064 generally (which might be named "makefile" or "Makefile" or even
2065 "foo.mk"), "Makefile" when talking about a specific makefile
2066 called "Makefile". This unclutters the text from weird quotes
2067 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2068 values" rather than "@var{foo}s" and similar constructs containing
2069 "}s". Use "Make rules" rather than "Makefile rules". Minor
2070 English-language improvements. Change the prefix "sub-" to "sub"
2072 Put blank lines around examples more consistently.
2073 Avoid "rather" and "very" as intensifiers.
2074 Avoid "will" as an auxiliary.
2075 (Limitations of Make): Split this node into....
2076 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2077 (Leading _ in Macro Names, Backslash-Newline-Newline):
2078 (Backslash-Newline Comments, Long Lines in Makefiles):
2079 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2080 (obj/ and Make, make -k Status, VPATH and Make):
2081 (VPATH and Double-colon, $< in Explicit Rules):
2082 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2083 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2084 New nodes, resulting from splitup of Limitations of Make.
2085 All cross-references changed. Raise the top node from
2086 a section to a chapter, and all subnodes accordingly.
2087 Redo the introductory wording to match the new organization.
2088 (Installation Directory Variables): Use an example that is
2089 closer to what Autoconf actually does. Mention that VPATH's
2090 value should not contain metacharacters or white space.
2091 (Fortran Compiler): Fix a VPATH bug in an example.
2092 (Leading _ in Macro Names): Mention that this problem is no longer
2093 of practical concern.
2094 (VPATH and Make): Reword the advice to make it clearer
2095 that Autoconf and Automake support VPATH in non-GNU make, but
2096 many packages have bugs in this area.
2097 ($< in Explicit Rules): Refer to Build Directories rather
2098 than using a (non-VPATH-safe) example.
2099 (Automatic Rule Rewriting): Mention the sort of disaster that
2100 can ensue with Solaris-style rule rewriting with VPATH.
2102 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2104 * doc/install.texi (Compilers and Options): Weaken the
2105 suggestion to use GNU make for VPATH builds.
2107 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2108 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2110 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2111 in regular expression.
2113 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2115 * doc/autoconf.texi (Installation Directory Variables):
2116 Drop extra @samp from `@table @samp' item.
2117 (Limitations of Usual Tools): Comment fix.
2118 Do not nest @samp just to point to other table items.
2119 (Writing testsuite.at) <AT_CHECK>: The second argument to
2120 `@dvar' is already @samp'ed.
2121 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2122 do not use @var in the second argument.
2124 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2126 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2127 $as_shell.exe too. Problem reported by Andreas Buening in
2128 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2130 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2132 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2133 `unused variable' compiler warning, for `-Wall -Werror'.
2134 Reported by Jaap Haitsma in
2135 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2137 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2139 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2140 case the compiler dumps core. Problem reported for
2141 OpenServer 5.0.7 by Tim Rice in
2142 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

2146 2006-06-06 Tim Rice <tim@multitalents.net>.

2149 "ERROR" only shows up in "make check" output if there is an

2173 * config/texinfo.tex: Sync from upstream.
2175 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2176 seen, invoke libtoolize with `--ltdl' argument.
2177 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2179 Suggested by Eric Blake.
2181 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

2201 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2203 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2205 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2206 `expout' as the last parameter.
2207 * tests/tools.at: Adapt to the above change.
2209 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2211 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2212 information about race-free implementations of mkdir.

2221 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2223 * NEWS: GNU make now recommended for VPATH builds.
2224 Mention that some macros are now documented to be obsolescent.
2225 * doc/autoconf.texi:
2226 Prefer "current" to "modern" to describe
2227 currently-used (albeit perhaps old-fashioned) hosts.
2228 Mention which ancient features no longer need to be worried about.
2229 setgid -> set-group-ID
2230 setuid -> set-user-ID (these are the Posix terms)
2231 Fix some misuses of "only".
2232 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2233 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2234 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

2246 Omit longwinded and obsolescent discussion of cp -f.
2247 Modernize discussion of expr, ls.
2248 (Limitations of Make): Modernize discussion of VPATH builds.
2249 Mention $? as a workaround in some cases.
2250 * doc/install.texi (Basic Installation):
2251 Mention "./configure; make; make install" first. Be more
2252 specific about why this file is generic. Remove unnecessary
2253 parens. Remove misleading "only". Remove obsolete advice
2254 about csh. Don't say "configure" takes awhile; say it
2255 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2256 and CC=c99 rather than CC=c89, as these are blessed by current
2257 Posix. Recommend GNU make if doing a VPATH build.
2259 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2261 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2262 examples involving shell prompts.

2265 and Paul Eggert <eggert@cs.ucla.edu>
2267 * doc/autoconf.texi (Here-Documents): Add details about the
2268 pre-ksh93g bug. Reword slightly to make it clearer. Consistently

2301 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2303 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2304 about quoting ac_try: quote all of it, if any of it seems suspicious.
2305 This means we don't have to worry about ${ or sed any more.
2306 Also, double-quote the case statement, to work around misuses via
2307 underquoting as reported by Ralf Wildenhues in
2308 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2309 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2310 undocumented and dangerous macro.
2311 Problem reported by Ralf Wildenhues in
2312 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

2322 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2323 since evidently some packages rely on the old, broken behavior.
2324 Problem reported by Ralf Wildenhues in
2325 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2326 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2327 pre-2006-05-26 definitions, but leave in the comments that
2328 these macros are dangerous and should not be used.
2329 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2330 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2331 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2332 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.

2335 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2337 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2338 the use of 'tr', since this is our only use of 'tr'.
2340 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2341 and Paul Eggert <eggert@cs.ucla.edu>
2343 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2344 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2346 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2348 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2349 the output file in the `${datarootdir}' test.
2351 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2352 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2354 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2355 mention of `datarootdir' in the input file(s), but literal
2356 `${datarootdir}' in the output file, and we haven't warned yet,
2357 then warn as well: the user may have (erroneously) used
2358 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2359 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2360 * tests/torture.at (datarootdir workaround): Extend this test.
2363 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2364 and Paul Eggert <eggert@cs.ucla.edu>
2366 * doc/autoconf.texi (autoheader Invocation): The first argument to
2367 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2368 alternatives and clear up the language a bit.
2370 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2372 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2373 ac_config_guess, ac_config_sub, ac_configure.
2374 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2375 Fix typo that prevented an unnecessary space from being removed.
2376 Problems reported by Ralf Wildenhues in:
2377 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2379 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2381 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2382 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2383 Don't use the term "thread-safe" to talk about mkdir race
2384 conditions, since the problem is more a process than a thread
2385 issue. Problem reported by Stepan Kasal in:
2386 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2387 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2388 the test for 'install' more closely. Look at MKDIR_P first.
2389 Look in the PATH, and at /opt/sfw/bin.
2390 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2391 Don't bother to try mkdir -p, since we already check mkdir --version;
2392 just look at the version number. (There's no easy way to check
2393 for race-free implementations.)
2394 * tests/tools.at (autoconf: subdirectories): Adjust to above
2395 changes, since MKDIR_P now might end in "/mkdir -p".
2397 * doc/autoconf.texi (autoheader Invocation): Mention that the
2398 first arg of AC_DEFINE_UNQUOTED must be a literal.
2399 Problem reported by Ben Pfaff in
2400 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2402 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2403 * doc/autoconf.texi (Special Chars in Variables): New section.
2404 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2405 (Installation Directory Variables): Quote $(datadir) better.
2406 (Limitations of Builtins): Describe some of eval's trickiness.
2408 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2409 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2410 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2411 in front of every arg, not just trailing args. Quote apostrophes.
2412 (_AC_EVAL_ECHO): New macro.
2413 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2414 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2416 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2417 exposed by quoting of eval argument. Put the command on line line
2419 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2420 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2421 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2422 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2423 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2424 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2425 Use eval more safely.
2426 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2427 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2429 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2430 lines, exposed by quoting of eval argument.
2432 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2433 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2435 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2436 initialization of `ac_cv_exeext', do not override it if it was
2437 already set, unless it was set to `no', for compatibility with
2438 Autoconf-2.13, and comment this.
2439 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2440 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2441 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2442 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2443 Document that this test may be overridden by setting
2446 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2448 Revert these two patches:
2450 2006-04-06 Eric Blake <ebb9@byu.net>
2451 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2452 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2455 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2456 Clean up _AC_COMPILER_EXEEXT* macros.
2457 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2458 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2459 ac_file to the name of the default output file and call
2460 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2461 initial `rm' of the candidate files...
2462 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2463 the same list in subsequent `rm' calls, and for the temporary
2464 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2465 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2466 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2467 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2468 no longer needed) by libtool. Make it a cache check.
2469 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2470 copied here by mistake.
2471 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2472 _AC_COMPILER_EXEEXT.
2473 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2474 _AC_COMPILER_OBJEXT directly.
2475 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2477 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2479 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2480 Fix description of how the buggy `sed' works.
2482 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2486 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2487 ENOLCK. Only mention `make -j' when applicable. Only raise
2488 fatal errors when `make -j' is involved. Improve error message.
2490 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2492 * doc/autoconf.texi (Here-Documents): We now know more about
2493 the variable expansion in here documents bug.
2494 Thanks to Tim Rice and Stepan Kasal.
2496 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2497 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2499 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2501 * tests/autotest.at (Multiline command from M4 expansion):
2502 No failure to be expected if the shell quotes newlines in
2503 commands in the `set -x' output. Report by Tim Rice.
2506 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2508 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2509 expansion in the here-documents used by config.status, as that
2510 runs afoul of the Korn shell version M-12/28/93d bug described in
2511 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2512 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2513 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2515 2006-05-23 Jim Meyering <jim@meyering.net>
2517 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2518 Fix typo introduced with 2006-04-02 change. It reversed the sense
2521 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2523 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2524 ac_dB slightly, to save bytes in the script.
2525 Max out at 50 lines, rather than 96; this is more likely
2526 (though not guaranteed) to avoid obscure 'sed' failures.
2528 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2530 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2531 `tr -d -' as bad option argument. Work around this by deleting
2532 an unrelated character.
2533 Report by Tim Rice <tim@multitalents.net>.
2535 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2536 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2537 Stepan Kasal <kasal@ucw.cz>
2539 * doc/autoconf.texi (Particular Programs): Do not promise that
2540 we always prefer the GNU version of the program, and that we
2541 search according to PATH; both rules can have exceptions.
2542 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2543 AC_PROG_SED. Move descriptions of limitations
2544 to the Limitations of Usual Tools section.
2545 (Limitations of Usual Tools) <sed>: Mention script length
2546 limitations with Solaris /usr/ucb/sed.
2547 <grep>: Fix wording for empty alternative. Mention that -c and
2548 -l should not be combined, and that -E and -F should not be
2551 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2552 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2554 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2555 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2557 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2559 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2560 AC_DEFINE is now passed to m4_pattern_allow.
2561 * NEWS: Mention that; likewise for AC_SUBST.
2562 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2563 the parameter to m4_pattern_allow.
2564 * tests/tools.at: Add a check for that.
2566 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2568 * lib/autoconf/status.m4: Fix typos.
2570 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2572 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2573 only the files that this macro generates.
2575 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2577 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2578 the HP-UX sed limitation of 99 commands, labels do not count.
2579 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2581 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2583 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2585 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2586 Import the following fix from coreutils:
2588 2006-01-13 Jim Meyering <jim@meyering.net>
2590 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2591 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2592 not double-quote uses of that variable, to accommodate the rare
2593 case in which getmntent is available in none of the libraries
2594 checked. This happens at least on FreeBSD 5.0.
2596 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2598 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2599 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2600 some other programs unwisely rely on these undocumented vars.
2601 But put in warning comments about them.
2602 Problem reported by Ralf Wildenhues in
2603 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2604 * NEWS: Document that these variables are intended to go away.
2606 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2608 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2609 and set the language to C++ (analogous to the equivalent Fortran
2612 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2613 * doc/autoconf.texi (C++ Compiler): Document it.
2614 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2617 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2619 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2620 that caused config.status to generate 100-command sed scripts; the
2621 portable limit is 99.
2623 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2625 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2626 variable `ac_d' instead of `d' to avoid infringing namespace.
2627 Report by Ralf Menzel.
2629 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2631 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2632 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2633 * tests/tools.at (autoconf: subdirectories): New test, taken from
2634 the corresponding problem report by Ralf Wildenhues in:
2635 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2637 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2638 Quote some uses of shell variables if they might suffer unexpected
2639 globbing. This doesn't fix all instances of quoting problems that
2640 I found, just the easy ones that look safe.
2641 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2642 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2643 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2644 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2645 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2646 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2647 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2649 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2650 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2652 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2654 * bin/autoreconf.in ($help): Reword according to the manual.
2655 Suggested by Olly Betts.
2657 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2658 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2660 * bin/autoreconf.in: Pass the directory argument to
2661 `require_configure_ac'. Fix comment.
2662 * tests/torture.at (Configuring subdirectories): Expose this.
2663 Reported by Olly Betts.
2665 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2667 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2668 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2669 Automake as follows:
2671 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2672 `$configure_in' instead of `configure.in', to preserve
2673 directory component.
2675 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2677 * config/config.guess, config/config.sub, config/texinfo.tex,
2678 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2680 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2682 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2683 test for C99 conformance; (bool) 0.5 is an integer constant
2684 expression, but (bool) -0.5 is not. Problem reported by Fedor
2685 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2687 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2689 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2690 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2691 Warn about obsolete install-sh files. Remove stray sentence
2692 fragment and fix cross reference.
2693 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2694 install -d; this undoes the 2006-05-10 change.
2695 (MKDIR_P): Mark with AN_MAKEVAR.
2696 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2697 that we don't require $INSTALL to be thread-safe. Move comments
2698 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2699 of AC_PROG_INSTALL. Output a message saying that we're checking
2700 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2701 MKDIR_P instead of AC_SUBST.
2702 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2703 Special magic for MKDIR_P, too.
2704 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2706 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2708 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2710 Sync from Automake, as follows:
2712 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2713 * config/install-sh: Initialize IFS, so field splitting isn't
2715 * config/mkinstalldirs: Likewise.
2716 * config/missing: Remove superfluous quotes. Replace all uses of
2717 `[' by `test', for consistency, and for..
2718 * config/missing (sed_minuso, sed_output): New variables.
2719 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2720 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2721 Fixes `missing' to detect `--output' for help2man. Fixes
2722 PR automake/483. Report by Dennis J. Linse.
2723 (autom4te): Document in `missing --help'.
2725 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2727 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2728 * config/install-sh: Don't use 'path' to talk about file names,
2729 as per GNU coding standards. Close a race condition reported by Ralf
2730 Wildenhues and Stepan Kasal. There is still a race condition
2731 on hosts that predate Posix 1003.1-1992, but we can't help this.
2732 Don't mishandle weird characters like space on pre-Posix hosts.
2733 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2734 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2735 AC_PROG_MKDIR_P from AS_MKDIR_P.
2736 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2737 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2738 earlier editions are not (including Automake 1.8.3).
2739 Do not suggest mkinstalldirs for thread-safety.
2740 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2741 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2742 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2743 presence of special characters and race conditions.
2744 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2745 in Autoconf's name space.
2747 2006-05-10 Bruno Haible <bruno@clisp.org>
2748 and Paul Eggert <eggert@cs.ucla.edu>
2750 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2751 from Automake with minor changes.
2752 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2754 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2756 * config/install-sh: Update to Automake CVS version, as follows:
2757 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2758 * lib/install-sh: Simplify the expr implementation of dirname.
2759 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2760 * lib/install-sh: Handle --, and diagnose unknown options.
2762 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2764 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2765 `./autom4te' to create `./testsuite', since the `all' target
2766 will ensure its presence, but `installcheck' should not create
2767 the uninstalled wrappers.
2769 * tests/torture.at (Unusual Automake input files): Skip if we
2770 detect automake < 1.8.
2772 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2774 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2775 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2776 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2779 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2781 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2782 munge (multiple) white space and other oddities.
2783 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2784 single quotes in variable assignment.
2785 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2786 and similar failures by adding multiple spaces, tabs, and other
2788 Report and different test suggested by Francesco Romani
2789 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2791 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2792 single quotes, we only need to search for single quotes; this
2793 both simplifies the search pattern, and makes us less
2794 susceptible to `echo' variations for arguments not containing
2796 (_AC_ARG_VAR_VALIDATE): Likewise.
2798 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2800 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2801 `$*' and IFS concatenation issue with traditional shells and
2802 bash-2.04. Report by Seanster@Seanster.com.

2884 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2886 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2887 since as_me isn't set yet.
2889 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2891 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2892 a few minor bugs in this area.

2927 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2929 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2930 Archive is not officially `GNU' any more. Update URL.
2931 (Defining Directories): Likewise
2932 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2934 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2936 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2937 newline from the `trap' code to finish `config.log'; the NetBSD
2938 /bin/sh resets the exit status after an empty command, as
2939 documented in doc/autoconf.texi.
2940 Reported by Dalibor Topic <robilad@kaffe.org>.
2942 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2944 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2945 Suggested by Bruno Haible.
2947 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2949 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2950 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2951 Instead, just list the shells that we know work.
2952 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2953 changed. Be more cautious about the _cv_ variable.
2954 * tests/tools.at (Syntax of the shell scripts): Check the
2955 _cv_ variable once, at first, to avoid an internal autoconf error
2956 when sh -n does not work.
2958 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2960 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2962 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2964 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2965 use ">&-" since we're only 99.999% sure that this is portable,
2966 and since the MinGW bug is fixed in a different way.
2967 * lib/autotest/general.m4 (AT_INIT): Likewise.
2969 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2971 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2972 before opening config.log, to avoid hitting a bug on MinGW.
2974 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2976 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2977 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2978 This works around a MinGW bug reported by Eric Paire.
2979 Make sure that all writes to the log file append to it,
2980 rather than possibly losing data.
2981 * lib/autotest/general.m4 (AT_INIT): Likewise.
2983 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2985 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2988 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2992 * configure.ac (AC_INIT): Bump to 2.59d.
2994 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2998 * Makefile.maint (news-date-check): Do not require a leading `*'
2999 before the release date in NEWS.
3001 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3002 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3004 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3005 the instantiated file do not contain the string 'datarootdir'
3006 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3007 @mandir@, replace the reference '${datarootdir}' by the value.
3008 * tests/torture.at (datarootdir workaround): New test.
3009 * NEWS: Advertise this temporary fixup.
3010 Based on a patch by Bruno Haible, reported and analyzed by
3011 Paul Eggert and Noah Misch.
3013 2006-04-12 Eric Blake <ebb9@byu.net>
3015 * tests/autotest.at (Debugging a failed test): Fix comment.
3017 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3019 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3020 all the changes since 2006-04-07.
3022 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3024 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3025 succeeded, but `ln -s file dir' failed, take care to remove the
3026 leftover target before the next test, to prevent its spurious
3027 failure; also make sure `ln file dir' works before selecting it.
3028 Thanks to Keith Marshall for pointing this out.
3031 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3032 assignments in `at_debug_args', so that we put them correctly
3033 in the `run' script.
3034 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3035 Reported by Eric Blake.
3037 2006-04-11 Eric Blake <ebb9@byu.net>
3039 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3040 top-level tests after micro-suite has been run. Used in...
3041 (Debugging a successful test, Debugging script and environment),
3042 (Debugging a failed test): ...these new tests. The first of these
3044 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3045 macro, split out from...
3046 (AT_INIT): ...here, so that using -d also generates a run script.
3047 Document that -d inhibits top-level logging.
3048 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3049 inhibits top-level logging; debug scripts are created.
3051 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3053 * tests/autotest.at (Empty test, Empty check): New test to check it.
3055 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3058 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3060 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3061 the files if a problem appears. Make the empty *.at files
3062 read-only, too. Proposed by Ralf Wildenhues.
3064 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3066 * config/Makefile.am: Add comment to force updated Makefile.in.
3068 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3069 space only patch to this file, this patch causes the Makefile.in
3070 files that include freeze.mk to be updated, and thus have a
3071 newer time stamp again, which in turn makes a pristine CVS
3072 checkout have correct time stamps.
3074 * Makefile.maint (cvs-sv): New macro, to be used..
3075 (config.guess-url_prefix, config.sub-url_prefix)
3076 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3077 point to CVS text checkout of Gnulib files.
3078 (copyright-check): Bump current year.
3079 (announcement): Do not hard-wire `./announce-gen'.
3080 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3082 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3084 (wget_files): Update config.guess, config.sub, texinfo.tex by
3085 `wget-update', now that their URLs work again.
3087 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3089 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3090 Problem noted by Paul D. Smith.
3092 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3094 * doc/autoconf.texi: Remove unused words from word list.
3095 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3096 .x-sc_trailing_space: New files.
3098 * doc/standards.texi: Sync from gnulib.
3100 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3101 `LIBOBJDIR' as experimental.
3103 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3104 with a target directory; it's internally implemented as `cp'
3105 anyway, but since Autoconf advertises the possibility to use
3106 a target directory when LN_S is `ln -s', we need to find out.
3107 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3108 analyzed by Keith Marshall <keith.marshall@total.com>.
3112 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3114 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3115 confdefs.h as-is. In general, if it has backslash-newline or the
3116 like, then it doesn't work either to sort or to remove empty
3119 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3121 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3123 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3125 * lib/autom4te.in (Automake-preselections): Preselect
3128 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3130 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3131 apostrophe within a single-quoted string, as this is the usual
3132 tradition and is easier to read than '"'"'. Don't rely on the
3133 shell treating "$/" like '$/'. Use a more-consistent indenting
3136 2006-04-09 Eric Blake <ebb9@byu.net>
3138 * tests/autotest.at (Backquote command substitution),
3139 (Multiline backquote command substitution): Remove mistaken
3140 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3142 (Parenthetical command substitution, Multiline parenthetical
3143 command substitution): here.
3145 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

3178 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3179 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3180 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3181 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3182 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3183 (Coding Style). Don't mention m4_expand_once.

3220 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3222 Revert the patch from 2006-04-01 and only improve
3223 _AS_DETECT_BETTER_SHELL:
3225 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3226 skip nonexistent directories.

3276 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3278 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3279 whether `set' quotes correctly: redirect stderr of the tested
3280 `set', and use a subshell, for Ultrix; use `sed' instead of
3281 `grep' for zsh `set' which may write binary output; match only
3282 at the beginning of a line, to avoid false positives.
3283 In order to avoid false positives by unrelated variables with
3284 multiline content, put the dump algorithm in a subshell and
3285 unset all variables containing newlines (except some which are
3286 special to the shell). Warn about cache variables that are

3406 (exclude_list): Exclude empty macros.
3407 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

3493 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3494 initial `rm' of the candidate files...
3495 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3496 the same list in subsequent `rm' calls, and for the temporary

3501 no longer needed) by libtool. Make it a cache check.

3503 copied here by mistake.

4219 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4221 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
4222 Factor functionality to..
4223 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
4224 `AC_SUBST($1)' in the public version.
4225 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
4226 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
4229 2005-11-01 Stepan Kasal <kasal@ucw.cz>
4231 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
4234 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4236 * NEWS: Move AH_HEADER mention to right place.
4238 2005-10-27 Stepan Kasal <kasal@ucw.cz>
4240 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
4241 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4243 2005-10-25 Stepan Kasal <kasal@ucw.cz>
4245 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
4246 conftst2.$ac_objext.
4247 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4249 2005-10-24 Stepan Kasal <kasal@ucw.cz>
4251 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
4252 conftest.o, to see whether the compiler really obeys; rm the object
4253 file before and after the test and register it with ac_clean_files.
4254 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4256 2005-10-21 Stepan Kasal <kasal@ucw.cz>
4258 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
4259 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
4260 code so that the most common case requires less forks.
4262 2005-10-20 Stepan Kasal <kasal@ucw.cz>
4264 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
4265 not portable; thanks to Paul Eggert and Alexandre.
4267 * NEWS: Fix an old typo.
4269 2005-10-20 Jim Meyering <jim@meyering.net>
4271 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
4272 the latter'', in two places.
4274 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
4276 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
4277 AC_LANG_PROGRAM, fixing a typo. Don't give details about
4278 the inner workings of AC_LANG_FUNC_LINK_TRY.
4279 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
4280 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4281 by the function rather than ignoring it.
4282 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4283 comparing its address. Intel's interprocedural optimization was
4284 outsmarting the old heuristic. Problem reported by
4287 2005-10-19 Stepan Kasal <kasal@ucw.cz>
4289 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
4291 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
4293 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
4294 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
4296 2005-10-04 Stepan Kasal <kasal@ucw.cz>
4298 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
4299 before removing it (chmod -R u+rwx); there are three instances of this.
4301 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4302 Stepan Kasal <kasal@ucw.cz>
4304 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4305 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4306 make its content writable before removing it. Remove an errorneous
4307 comment from the end, where the logs of the failed tests are copied
4308 to the main log file.
4310 2005-09-27 Stepan Kasal <kasal@ucw.cz>
4312 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
4313 in case the computer is too quick. Double quote the configure.ac
4316 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
4317 problems if the testsuite were running too fast.
4319 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4321 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4322 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4323 (which belong to Xt, not X itself). See Debian bug 327655.
4324 * NEWS: Mention this.
4326 2005-09-07 Stepan Kasal <kasal@ucw.cz>
4328 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
4330 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
4332 * config/move-if-change: Don't output "$2 is unchanged";
4333 suggested by Ben Elliston. Handle weird characters correctly.
4335 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4337 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4338 calls, so that the final expansion of this macro is shorter.
4339 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4340 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4341 the cleanup there. Use AS_VAR_* macros, to be more general.
4342 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4344 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4346 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
4348 2005-09-01 Stepan Kasal <kasal@ucw.cz>
4350 * doc/autoconf.texi (Configuration Headers): Add an index entry
4353 2005-08-26 Pavel Roskin <proski@gnu.org>

4356 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
4359 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4361 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4362 The previous patch didn't work, so try a better one.
4364 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4366 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4367 in the example. Reported by Bruno Haible.
4368 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4369 "if $undefined_var;" succeeds with my shell.
4371 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4372 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4373 but change the m4_divert_text to m4_divert_once.
4375 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4377 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4378 Work around bug in Solaris /usr/xpg4/bin/awk.
4379 The bug is present in at least Solaris 8 through 10.
4381 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4383 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4384 some evil values and relying on the fact that $* concatenates the
4385 parameters by the first character from IFS.
4387 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4388 Stepan Kasal <kasal@ucw.cz>
4390 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4391 first header appears, define AH_HEADER.
4392 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4393 Update limitations about when to call AC_CONFIG_HEADERS.
4394 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4395 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4396 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4397 ``Configuration Actions''; fix their index entries.
4399 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4400 options correctly. Process N-M as M-N if M is smaller than N.
4401 Process ranges correctly so that N-N will run only N.
4402 Sort and uniquify the tests that will be run. If there is more
4403 than one test, reinsert the banners for the tests.
4404 * tests/autotest.at (Keywords): Unmark XFAIL.
4406 2005-08-23 Stepan Kasal <kasal@ucw.cz>
4408 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4409 before passing the macro name to AH_TEMPLATE.
4411 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4412 now opens log after option processing; in particular, --version
4413 and --help do not touch config.log.
4415 * Makefile.maint: Revert the change from 2005-08-12.
4417 2005-08-22 Stepan Kasal <kasal@ucw.cz>

4423 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4425 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4426 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4429 * doc/autoconf.texi (Defining Symbols, Changed Results):
4430 Prepend to LIBS, not append, in examples.
4432 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4434 When building in place, set srcdir="."; suggested by Tim Van Holder.
4436 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4437 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4438 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4439 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4440 does not mean "no --srcdir option".
4442 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4444 * tests/autoscan.at (autoscan): New file.
4445 * tests/suite.at: Use it.
4446 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4447 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
4449 * tests/autotest.at (Keywords): Test keywords combinations.
4451 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4453 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4454 add "2>&1"; gzip 1.2.4 prints help on stderr.
4456 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4458 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4459 was pushdef'ed twice while popped only once. Push it only once.
4460 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4462 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4464 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
4465 prefixed by mere "===", not "configure: === ".
4467 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
4469 * Makefile.maint: Update from Bison.
4471 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4472 "<tab>" in comment, so that the point is understandable.
4474 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4476 Rewrite substantial part of lib/autoconf/status.m4.
4477 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4478 and CONFIG_COMMANDS are not processed in four separate loops.
4479 Instead, there is one main loop. This alows that the common code
4480 is expanded only once, thus config.status (and configure) is smaller.
4482 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4483 the AC_LIST_FILES and cousins macros are no longer used.
4485 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4486 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4487 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4488 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4489 contain the initialization, nor the for loop, nor the associated
4490 commands; all these go to ...
4491 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4492 _AC_OUTPUT_CONFIG_STATUS.
4493 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4494 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4495 (_AC_OUTPUT_FILE): The creation of the sed script ...
4496 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4497 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4498 _AC_OUTPUT_MAIN_LOOP.
4499 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4500 _AC_CONFIG_COMMANDS): Use ...
4501 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4502 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4503 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4504 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4505 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4506 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4508 (_AC_CONFIG_UNIQUE): Update.
4509 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4510 Replaced by this ...
4511 (_AC_LIST_TAGS): ... new common macro.
4512 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4513 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4514 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4515 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4516 this didn't belong to the `config commands' section.
4517 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4518 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4519 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4520 to the `config commands' section either.
4521 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4522 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4524 ... and many changes to the comments nearby.
4526 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4527 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4528 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4529 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4530 (#define header templates): The comment at the top of the generated
4531 header now includes the name(s) of the source file(s).
4533 Several unrelated small changes:
4535 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4536 parameter to AC_DIAGNOSE.
4537 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4538 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4539 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4540 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4542 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4543 in AC_OUTPUT doesn't double-quote it either.
4544 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4547 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4549 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4550 versions of Portland Group compiler produce single- and double-quoted
4551 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4552 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4554 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4556 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4557 This is a corrected version of yesterday's patch.
4559 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4561 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4562 path, too; insert a "===" to emphasize the line.
4564 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4565 ac_cv_build_alias to ac_build_alias.
4566 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4568 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4569 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4570 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4571 (AC_ARG_VAR): ... here.
4572 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4575 Keep a list of all precious variables and process them with one simple
4576 for loop, instead of expanding all commands, or, OTOH, complicated
4577 processing of output of "set".
4578 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4579 variable names in new macro...
4580 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4581 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4582 a loop to assign all ac_env_* and ac_cv_env_* variables.
4583 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4585 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4586 its value to shell variable ac_precious_vars and call
4587 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4588 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4589 _AC_ARG_VAR_VALIDATE.
4591 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4592 and the AC_SUBSTs ...

4596 the ac_subst_files section in config.log.

4609 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4610 They are generated by the Tru64 v5.1B shell.
4612 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4614 Fix my changes from 2005-07-01; reported by Noah Misch.
4615 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4616 description, the macro now accepts only a single tag.
4617 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4619 Fix cases when the varsions of Autoconf and Autotest don't match.
4620 Reported by Noah Misch.
4621 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4622 at_top_builddir, for compatibility with older autotest.
4623 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4624 is not set, use at_top_builddir, for compatibility with older
4625 versions of autoconf.
4627 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4629 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4630 Problem reported by Patrick Welche.
4632 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4634 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4635 sed substitution command, so that we allow | in program prefixes
4636 and program suffixes. (& is a problem anyway; we're not fixing
4638 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4639 configure_input, top_builddir, srcdir, etc.
4640 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4641 PATH_SEPARATOR in AUTOTEST_PATH.
4643 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4645 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4646 for loop over config.site files using `set', to allow
4647 directory names containing IFS characters.
4649 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4651 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4652 directories with weird names. Apparently some people like living
4653 on the edge. However, improve the test that "pwd" actually does
4654 report a name for the working directory.
4655 * NEWS: Remove the claim that we test for funny chars in dir names.
4657 2005-07-01 Stepan Kasal <kasal@ucw.cz>
4659 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

4669 about #include <config.h>.
4670 (Generic Functions): Mention the Gnulib project.
4671 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4673 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4674 document to output the default config_* lists to config.status.
4675 Don't recognize option --file, if the functionality is not there.
4676 Likewise for --header; moreover, recognize --he and --h as shortcuts
4677 for --help in that case.

4699 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
4701 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
4702 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4703 (AC_SUBST): Call it.
4704 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4705 the directory specific variables; but don't call it for configure_input.
4707 2005-06-28 Derek Price <derek@ximbiot.com>
4709 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4712 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4714 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

4731 from Justace Clutter.
4732 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4733 variable into diagnostic. Make the diagnostic an error, not a warning,
4734 because we really don't support spaces and suchlike in dir names.
4735 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4736 Don't worry about backslashes in srcdir; it can't happen now.

4747 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4749 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4750 that '\|' is not allowed in BREs; recommend using newline separated
4751 list of patterns instead of multiple -e options.
4753 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4755 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4763 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4764 b, t, r, w commands require single space, while : cannot have any.
4765 (Special Shell Variables): Fix sed code this in the example.
4766 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4767 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4769 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

4775 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4777 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4779 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4780 * doc/autoconf.texi:
4781 Don't mention Solaris versions so much, if a
4782 problem is common to all extant versions of Solaris. Say "SunOS
4783 4" instead of "SunOS" for SunOS 4.
4784 (awk): Mention more of the limitations of traditional Awk.
4785 (cat): Don't talk about cat -v.
4787 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

4795 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4796 on Mac OS X 10.4 reported by Peter O'Gorman in:

4801 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4803 * doc/autoconf.texi: "filesystem" -> "file system".
4804 "behaviour" -> "behavior".
4805 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
4806 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4808 * lib/m4sugar/m4sh.m4: Likewise.
4809 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4810 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4812 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4813 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4814 to update the man page. That way, we don't have to check in new
4815 man pages every month.

4825 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4827 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4828 -u, since it outputs chatter if the input files are the same.
4829 Problem reported by Ralf Menzel.
4831 2005-06-08 Derek Price <derek@ximbiot.com>
4833 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4834 renaming them since they are about to be redefined anyhow.
4836 2005-06-08 Derek Price <derek@ximbiot.com>
4838 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4839 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4840 Move m4_undefine to alphabetical order.
4842 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4844 * README: Recommend GNU M4 1.4.3 or later.
4845 * doc/autoconf.texi (Introduction): Likewise.
4846 Reword to avoid some formatting glitches.
4847 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4848 Clarify explanation of HP compiler bug.
4849 Redo example output tp match current CVS snapshot.
4850 Use @example.org in email addresses when the examples
4851 might get inadvertently cut-and-pasted into user code.
4852 Remove example of autom4te usage that doesn't seem to work now.
4853 Use modern AC_INIT (except when the example is meant to be
4854 shown with Autoconf 2.13).
4855 Update ksh info for Solaris 9 and later.
4857 Modernize description of Automake versions a bit.
4858 Don't claim a future version of Autoconf is near.

4864 follows its own advice about quoting better.
4865 Reword to avoid some formatting glitches.
4866 * doc/installt.exi: Reword to avoid some formatting glitches.
4868 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4869 Tru64 ksh pattern matching bug. Reported against Libtool by
4870 Albert Chin <libtool@mlists.thewrittenword.com> and
4871 Nicolas Joly <njoly@pasteur.fr>.
4873 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4875 m4_cdr of one-member list was [[]] (one-member list containing an
4876 empty string) instead of [] (an empty list. Callers were skewed to
4877 match this misbehaviour. As a consequence of this:
4878 - m4_foreach([x], [], [foo]) expanded to `foo', while
4879 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4880 This bug has been fixed:
4882 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4883 expand to an empty string; print error msg if called without
4885 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4886 misbehaviour; handle [] and [[]] correctly.

4892 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4894 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4896 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4897 swallow records with more than 99 fields.
4898 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4899 parse the long line.
4901 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4903 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4904 swallow literals longer than 399. Reported by Ralf Wildenhues.
4905 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4906 to workaround this limitation.
4908 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4910 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4911 to gfortran, and make these the first two compiler names
4912 checked (following the general autoconf preference for gcc).
4914 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4916 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4917 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4918 (testsuite): Make sure autotest.m4f is up-to-date before using it.

4922 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4923 expression of unbounded size when processing the --list
4924 option. This runs afoul of a limit of 399 bytes per regular
4925 expression on AIX. Problem reported by Ralf Wildenhues.
4927 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

4930 * doc/autoconf.texi (Particular Headers): Reword example
4931 for multiline stdbool replacement.
4932 (Setting Output Variables): Reword text a bit. Don't
4933 give all the details about |#_!!_#|.
4934 Reword description of line replacement.
4936 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4938 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4939 now contain newlines, and substituted files must be referenced on
4940 a line alone; the sed scripts to substitute them are now very
4942 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4943 commands can be put in a sed script portably.
4944 * doc/autoconf.texi (Setting Output Variables): Document above
4945 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4946 use of multiline substitution.

4956 * tests/local.at: Don't attempt to check for negated character
4957 classes in shell scripts. The test was too brittle.
4959 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4961 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4962 * doc/autoconf.texi (Limitations of Builtins): Document this
4965 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4967 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4968 common code; used in many places in the tree.
4969 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4970 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4972 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.

4975 messages when ac_unique_file is not found.
4976 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4977 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4978 commands, for consistency with AC_MSG_ERROR and such.
4980 * bin/autoconf.as: Make more use of "shift 2" in option processing.

4993 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4994 (ac_top_builddir): ... this ...
4995 (ac_top_build_prefix): ... to this; the old name is also kept, for
4996 backward compatibility.
4997 (ac_top_builddir_sub): New variable, without the trailing slash,
4999 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

5013 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
5014 argument to m4_foreach. I guess it was necessary in the past,
5015 but I think it's a no-op now.

5019 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5020 ``cat <<_ACEOF'' commands to one.

5141 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5142 by AC_DEFINE; it was a mistake.
5143 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5145 2005-04-25 Stepan Kasal <kasal@ucw.cz>

5212 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5213 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5214 whole-archive (-zallextract, -zdefaultextract) options in the hope of

5221 a directory whose name contains a special character like space,

5236 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5237 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5238 ac_pwd, and quote srcdir.
5239 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5241 * doc/autoconf.texi: Fix some systematic formatting problems.
5242 ".)" needs a following @: if not at the end of a sentence, and
5243 similarly for "!)". "etc." should be preceded by a comma.
5244 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5246 2005-03-22 Bruno Haible <bruno@clisp.org>
5248 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's

5260 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5261 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5262 from a Common Lisp's `cl'.
5263 (AC_PROG_CXX): Behave according to the documentation: don't
5264 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5265 make the variable CCC precious; use `cl.exe', not `cl'.

5268 Alexandre Duret-Lutz <adl@gnu.org>
5270 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5271 /dev/null, as "configure" shouldn't read stdin, and this insulates
5272 us from problems (e.g., when testing for "cl"). Also, do this
5273 redirection before invoking "hostname" or "uname", and keep the
5274 original input stream available via...
5275 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5276 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

5288 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5289 newline if neither \c nor -n work, as that would output two
5290 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5292 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5294 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5295 This causes that any required macros inside will get before the if.

5298 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5300 Undo previous change, except keep the change to
5301 lib/autoconf/programs.m4 that replaced grep with shell
5302 pattern-matching. This is because net-snmp configure reads stdin.
5303 Reported by Noah Misch.

5307 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5308 from /dev/null, as "configure" shouldn't read stdin, and this
5309 insulates us from problems (e.g., when testing for "cl").
5310 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5311 before invoking "hostname" or "uname".
5312 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5313 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5314 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5315 "</dev/null" since it's now done at the top of 'configure'.
5316 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5317 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5318 Also, replace grep with shell pattern-matching, to save a process.

5322 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5323 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5324 avoid thinking that Allegro Common Lisp's "cl" command is a C++

5340 * doc/autoconf.texi: Use @acronym for DJGPP.
5341 Fix some @code's that should have been @env's, and vice versa.
5342 Sort environment variable names.
5343 Mention that shells no longer inherit IFS.
5344 Don't recommend PATH_SEPARATOR=';' so strongly.
5345 Mention that $RANDOM might expand to the empty string.
5346 "symlink" and "soft link" -> "symbolic link".

5423 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

5486 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5487 Update the long comment explaining it.
5489 m4_require no longer writes an ``is required by'' line to the
5490 execution stack. It contains only one bit of non-redundant
5491 information: that the macro was required, not called. And even
5492 this bit is useless in most situations: have you ever met a macro
5493 which both calls and requires the same macro?
5495 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5496 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5501 execution stack; slightly improve the out-of-a-defun error message.
5502 (_m4_divert_grow): New macro, counter for the temporary diversions.
5503 (_m4_require_call): Use it.
5504 * tests/m4sugar.at (m4_require): Expect output without the
5505 ``is required by'' messages.

5544 Warn about newline stripping in `` and $(). Update Solaris
5546 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5547 X insulates us from future changes to Posix.

6068 * Makefile.maint (wget_files, cvs_files):
6069 Remove ansi2knr.c; nobody uses it.
6070 (ansi2knr.c-url_prefix): Remove.
6071 (cvs-update): Fix test for failure. I don't know why it ever
6074 * doc/autoconf.texi: Update URLs, some of which went stale.
6075 Use @uref rather than @href.
6077 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
6078 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
6080 * config/config.guess, config/config.sub, config/elisp-comp,
6081 config/install-sh, config/mkinstalldirs, config/texinfo.tex,

6093 to be consistent with the terminology of the GNU coding standards.

6097 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
6098 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
6099 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
6100 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
6102 More fixes to support spaces in the name of the build directory.
6103 This isn't a complete fix but it's an improvement.
6105 * bin/autoconf.as (autom4te_options): New var.
6106 Use it instead of appending to AUTOM4TE, so that we can allow
6107 spaces in the build directory's absolute name.
6108 * bin/autoheader.in ($autoconf): Allow spaces in file names.
6109 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
6110 AT_CHECK_NOESCAPE): Likewise.

6126 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
6128 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
6130 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6131 for compatibility with Automake 1.4. Reported by J C Fitzgerald in

6134 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6136 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.

6159 with pdksh, too. Problem reported by Patrick Welche via
6161 * doc/autoconf.texi (Shellology): Note that set -o posix is
6162 useful for pkdsh, too.
6164 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6166 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6167 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6168 Don't fail if ENV or BASH_ENV is readonly.
6169 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6170 etc. are read only. Problem reported by Ludovic Courtes.
6172 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6174 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6175 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6178 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6180 * doc/autoconf.texi (File System Conventions): Warn about
6181 names like "aux". Problem reported by Eric Blake.
6183 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6184 by zero instead of array size, so that we can use any arithmetic
6185 constant expression (instead of requiring an integer constant
6186 expression). This allows us to test expressions like DBL_MAX <
6187 LDBL_MAX, which didn't conform to the C standard using the old
6189 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6190 now that we can do floating-point tests at compile time.
6192 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6194 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6195 and LDBL_EPSILON, as the resulting expression isn't an
6196 integer constant expression and violates the C standard.
6197 Problem reported by Nelson H. F. Beebe. Also, check
6198 for "L" suffix, and check that long double doesn't have
6199 worse range or precision than double, that mixed-mode
6200 arithmetic doesn't generate a diagnostic, that double
6201 constants fit in long double.
6203 2004-06-03 Kevin Ryde <user42@zip.com.au>
6205 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6206 malloc(0) and realloc(NULL,size).

6211 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6213 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6214 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6217 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6219 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6220 can be rewritten using if-then-else. Suggested by Bruno Haible.
6222 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>

6225 Problem reported by Stepan Kasal.
6227 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6229 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6230 change). Patch reported by Ralf Wildenhues in
6231 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6233 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6234 function F exists if the compiler and linker let you compile an
6235 expression like (F != 0). Recent versions of GCC optimize away
6236 the reference to F in that case, since every function address must
6237 be nonzero, so the link succeeds even if F does not exist.
6238 Problem reported by Manu in
6239 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6241 * doc/autoconf.texi (Systemology): Standardize on the spelling of

6253 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6254 referencing AC_FUNC_STRERROR_R.
6256 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6257 note pessimistic assumption when cross compiling.
6259 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6261 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6262 (until 2004) invoked subcommands with sh -e, contra POSIX.
6263 Reported by Kevin Ryde.
6265 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6267 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6268 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6269 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6270 `test -f " /usr/bin/grep"', which _always_ failed.
6271 (AC_PROG_SED): Ditto bogus PATH fix.
6272 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6273 requires that grep correctly supports _multiple_ `-e' options, rather
6274 than stating only that grep should accept `-e'.
6276 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6278 Port to C99, which requires that 'exit' be declared.
6280 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6281 to ensure that stdlib.h is included.
6282 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6283 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6284 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6285 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6286 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6287 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6288 when using 'exit' in a test; C99 requires that 'exit' be declared.
6290 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6292 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6293 now prefers 'grep' implementations that accept -e.
6294 (Limitations of Usual Tools): Describe problems of traditional
6295 egrep and fgrep with long input lines, and of traditional grep
6297 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6298 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6299 All callers changed. Append /usr/xpg4/bin to the PATH, for
6301 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6302 the user with complaints about multiple -e options.
6303 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6304 Define it with AC_PROG_GREP.
6305 * configure.ac (AC_PROG_GREP): Add.
6306 * lib/freeze.mk (GREP): New macro.
6308 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6310 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6311 a possible candidate only after all others fail, rather than
6312 consulting it first. This improves backward compatibility by
6313 better reflecting the way shell selection occurred in previous
6314 versions of Autoconf, and should help to avoid triggering latent
6315 problems in other packages, such as the one in Automake where zsh
6316 is not handled robustly:
6317 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6318 Although it is not Autoconf's responsibility to work around
6319 problems in Automake, it nevertheless makes sense to avoid
6320 introducing unnecessary incompatibilites.
6322 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6323 Gary V. Vaughan <gary@gnu.org>
6325 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6326 how deeply nested we are when a suitable tool is found, set the
6327 ac_path_TOOL_found flag.
6328 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6329 nested we are in this macro. Break out of all 3 nested loops if
6330 ac_path_TOOL_found is set.
6332 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6334 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6335 of the _AS_PATH_WALK loop too if GNU flavor is found.
6337 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6339 * doc/autoconf.texi (Limitations of Make): Update documentation
6340 for `$<'. New entry `Long lines', based on a report from Simon
6341 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6342 paragraph about DJGPP, based on a mail from Richard Dawe.
6344 2004-04-20 Paul Eggert <eggert@twinsun.com>
6346 * tests/c.at (C keywords): Don't assume that GCC supports
6347 "restrict" and "inline", as sufficiently-old GCC versions do not
6348 (also, GCC configured to be in pedantic C89 mode does not).
6349 Problem reported by Sumit Pandya in:
6350 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6352 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6353 consider -g to work if it generates warnings when plain compiles
6354 don't. Problem reported by Braden McDaniel in:
6355 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

6361 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6362 linker output files before linking, to work around IRIX 6 linker bug.
6363 Problem reported by Rainer Orth in:
6364 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6366 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6368 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6369 best tool so far counter rely on the tool path variable name to
6370 avoid checks for one tool being affected by the results of running
6371 the length check on a previous tool.
6373 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6374 match expression argument, as different greps have different
6375 regular expression flavours.
6376 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6378 (AC_PROG_EGREP): Pass 'EGREP$'.
6379 (AC_PROG_GREP): Pass 'GREP$'.
6381 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6383 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6384 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6386 2004-03-29 Paul Eggert <eggert@twinsun.com>
6388 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6389 Types, Specific Compiler Characteristics, System Services,
6390 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6391 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6392 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6393 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6395 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

6406 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6407 now defines HAVE_DECL_TZNAME if it is declared, when
6408 HAVE_STRUCT_TM_TM_ZONE is not defined.
6409 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6410 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

6419 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6421 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6422 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6423 H. F. Beebe for the bug report.
6425 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6427 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6428 quoted -cmdline argument in Portland Group compiler (bug
6429 reported by Jeffrey J. Barteet).
6431 2004-03-25 Kevin Ryde <user42@zip.com.au>
6433 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to

6477 2004-03-03 Paul Eggert <eggert@twinsun.com>
6479 * bin/Makefile.am (edit): Don't use $< in a context where
6480 POSIX doesn't require support for it. Use $@.in instead.
6481 Problem reported by Anthony N. Frasso in
6482 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

6493 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
6494 is not always thread-safe. Report from Nathanael Nerode.
6496 2004-02-18 Paul Eggert <eggert@twinsun.com>
6498 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6499 problem on QNX reported by Stephen Rasku in

6511 AC_SUBST provides no portable way to escape literal newlines.
6513 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6514 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6515 Darwin uses -lcrt2.o and there's little point to cataloging all
6516 the system variants. Partial fix reported by Andreas Waechter in:

6535 correctly the behavior of the third argument. Document
6536 what the three macros that AU_DEFUN defines do. Fix
6537 warning message when the third argument includes $0
6538 (reported by Alexandre Duret-Lutz).

6541 Eric Sunshine <sunshine@sunshineco.com>
6542 Paul Eggert <eggert@twinsun.com>
6544 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
6545 (AS_INIT): Output shell initialization there. Removed optional
6546 parameter. Expand _AS_SHELL_FN_SPY.
6547 (AS_INIT_WITH_SHELL_FN): Removed.
6548 (_AS_SHELL_FN_SPY): New macro.
6549 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
6551 (AS_SHELL_SANITIZE): Remove loop to find better shell
6552 and documentation for the parameter.
6553 (_AS_DETECT_BETTER_SHELL): Move it here.
6554 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
6555 (_AS_RUN): Move it here, support testing with eval.
6556 (AS_REQUIRE_SHELL_FN): Require shell functions when
6558 (_AS_LINENO_WORKS): Put around braces, we do not

6560 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
6561 use AS_INIT_WITH_SHELL_FN.
6562 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6564 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6566 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
6567 * doc/autoconf.texi: Don't say that the third parameter
6569 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
6570 (AU_DEFUN): Honor the third parameter, create autoupdate
6571 macros with AU_DEFINE.
6572 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
6573 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
6574 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
6575 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
6576 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

6592 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6593 2003 (except 1997) to the list of copyright years. This undoes
6594 the 2003-05-22 change, which removed the older years from the list.
6595 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6597 2004-01-27 Gary V. Vaughan <gary@gnu.org>
6598 Albert Chin-A-Young <china@thewrittenword.com>
6600 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
6601 grep or ggrep program in PATH that accepts as long lines as
6603 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
6605 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
6606 egrep and fgrep respectively if $GREP -E/-F don't work.
6607 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6608 _AC_PROG_GREP, and AC_PROG_SED.
6609 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the

6611 (AC_PROG_SED): Use it.
6612 * doc/autoconf.texi (Particular Programs): Document the changes.
6615 2004-01-27 Paul Eggert <eggert@twinsun.com>
6617 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
6618 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6619 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
6620 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
6622 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6623 bin/autoconf.in, config/Makefile.in, config/config.guess,
6624 config/config.sub, config/install-sh, config/mdate-sh,
6625 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,
6626 lib/Makefile.in, lib/Autom4te/Makefile.in,

6639 2004-01-26 Paul Eggert <eggert@twinsun.com>
6641 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6642 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6643 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6644 not <inttypes.h>. Problem reported by Tim Mooney in
6645 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6646 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6649 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6650 otherwise "make check" fails because it forbids cmp (I guess
6651 because cmp treats files as binary on DOS-like systems).
6653 * tests/mktests.sh: Update copyright date to 2004, since some tests
6654 have changed in 2004.
6656 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6658 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6659 non-truncating sed or gsed program in PATH.
6660 * tests/acprograms.at: Add it.
6661 * doc/autoconf.texi (Particular Programs): Document it.
6664 2004-01-15 Paul Eggert <eggert@twinsun.com>
6666 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6667 -std1 disables some useful extensions on Tru64. Problem reported
6669 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6671 2004-01-14 Paul Eggert <eggert@twinsun.com>
6673 * doc/autoconf.texi (Programming in M4sh): Document that
6674 AS_MKDIR_P succeeds if the destination is a symbolic link
6675 to an existing directory.
6676 (Limitations of Usual Tools): Note that mkdir -p might not
6677 succeed on symlinks to directories.
6679 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6681 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6682 * bin/autoheader.in: Grammar fix in message.
6683 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6684 Test for dir before calling mkdir -p. (trivial changes)
6686 2004-01-13 Eric Blake <ebb9@byu.net>
6688 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6689 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6691 2004-01-10 Jim Meyering <jim@meyering.net>
6693 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6695 2004-01-09 Paul Eggert <eggert@twinsun.com>
6697 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6698 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6699 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6700 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6701 AC_COMPILE_IFELSE, since we now assume our caller invokes
6702 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6703 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6704 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6705 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6707 2004-01-07 Paul Eggert <eggert@twinsun.com>
6709 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6710 `"'...'"`, as it's confusing (and I suspect it may not work on
6711 some platforms). The code was incorrect anyway, as it assumed
6712 that \$ evaluated to itself in that context. Reported by
6713 Alexandre Duret-Lutz.
6715 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6717 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6718 and _LT_AC_TAGCONFIG.
6720 2004-01-06 Paul Eggert <eggert@twinsun.com>
6722 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6723 example, and add more examples. Reported by Eric Sunshine.
6725 2004-01-05 Paul Eggert <eggert@twinsun.com>
6727 * doc/autoconf.texi (Limitations of Usual Tools):
6728 Remove warning against "rm -fr" introduced yesterday; it
6731 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6732 autoscan, autoupdate, ifnames): Don't use chmod -w.
6733 * lib/Makefile.am (autom4te.cfg): Likewise.
6734 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6737 2004-01-04 Paul Eggert <eggert@twinsun.com>
6738 Paolo Bonzini <bonzini@gnu.org>
6740 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6741 by doing lineno substitution only on lines containing "$LINENO".
6743 2004-01-04 Paul Eggert <eggert@twinsun.com>
6745 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6746 Use "rm -f" to remove conftest.sed, not plain "rm".
6747 Bug reported by David Relson in
6748 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6750 * Makefile.am (autom4te-update):
6751 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6752 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6753 * doc/autoconf.texi (Guidelines): Likewise.

6760 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6762 * doc/autoconf.texi (Limitations of Usual Tools):
6763 Warn against "rm -fr".
6765 2004-01-03 Paul Eggert <eggert@twinsun.com>
6767 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6768 -c -o might not work. From a suggestion by Kevin Ryde.
6769 (C Compiler, Generating Sources, Limitations
6770 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6771 Don't put '-o' after non-options, as POSIX doesn't allow this.
6772 Mention that cc's name might be gcc or c89 or whatever.
6774 2004-01-04 Kevin Ryde <user42@zip.com.au>
6776 * doc/autoconf.texi: Add various further index entries.
6778 2003-12-29 Paul Eggert <eggert@twinsun.com>
6780 * bin/autoreconf.in (autoreconf_current_directory):
6781 Fix typo: mkdir without umask arg.
6783 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6785 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6786 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6787 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6788 explanation clearer.

6798 * configure: Regenerate.
6799 * tests/atlocal.in: Store the result here.
6800 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6801 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6802 of explicitly testing.

6804 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6805 * tests/tools.at (Syntax of the shell scripts): Simplify
6806 using AT_CHECK_SHELL_SYNTAX.

6820 Extracted from AS_SHELL_SANITIZE.
6821 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6823 (AS_SHELL_SANITIZE): Move reinvocation code from
6824 _AS_LINENO_WORKS, use it to find out if shell
6826 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6828 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6829 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

6890 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6891 than $target since the latter is not usual, add guidelines on when to
6892 use or not use the system type.
6894 2003-11-12 Derek Price <derek@ximbiot.com>
6896 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
6897 typo misrepaired by an auto-spellcheck.

6914 2003-11-05 Alexandre Duret-Lutz <adl@gnu.org>
6916 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
6917 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,
6918 and ac_abs_top_srcdir are absolute paths.

6969 * bin/autom4te.in (&freeze): Use a less likely warning separator
6970 than `\n\n', so that `\n\n\n' is valid in warnings.

7068 Issue a more-informative diagnostic.
7069 Problems reported by Eric Sunshine.
7071 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7073 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7074 -mGLOB_options_string stuff for Intel ifc, which can cause
7075 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
7076 pattern-matching instead of grep.

7096 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
7098 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7099 cache variable instead of $G77 to decide whether to include -O2,
7100 since $G77 is specific to Fortran 77.
7102 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7104 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
7105 free" flag. Re-order flags tested into rough order of popularity.
7107 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7109 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7110 arguments so that it can be used with syntax identical to
7111 AC_PROG_F77, and so that we can more easily decide to
7112 remove/deprecate the DIALECT optional argument in the future if it
7114 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7115 non-freeform-supporting compilers. Document freeform flags.

7124 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
7125 * bin/autoreconf.in (autoreconf_current_directory): Create the
7126 AUX_DIR if needed, for sake of automake --add-missing etc.
7127 Suggested by Alexandre Duret-Lutz.
7129 2003-10-03 Akim Demaille <akim@epita.fr>
7131 * configure.ac: Quotation and formatting changes.

7178 Problem reported by Lars J. Aas in
7179 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
7180 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7181 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

7184 2003-09-26 Akim Demaille <akim@epita.fr>
7186 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7187 directory for AC_CONFIG_COMMANDS' first argument exists.
7188 This makes valid the invocation of _AC_SRCPATH that follows.
7189 Reported by Eric Sunshine.
7190 * doc/autoconf.texi (Configuration Commands): Adjust.
7192 2003-09-26 Akim Demaille <akim@epita.fr>
7194 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7195 Reported by Ralf Corsepius.

7213 The test suite are sometimes assigning timings incorrectly.
7214 Reported by Henk Krus.
7215 Diagnosed by Nicolas Joly.
7217 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7219 Instead of making AT_help a sequence of assignments to grow
7220 $at_help_all, just make AT_help_all be the growing contents of
7221 $at_help_all, and make a single assignment in...
7223 (at_times_skip): Flip the meaning and rename as...
7225 (AT_INIT): When summarizing the test that ran, remove
7226 $at_times_file after use, and check it is present before trying to

7233 * bin/Makefile.am (edit): Handle '@configure_input@'.
7234 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
7235 (ifnames): chmod -w.
7236 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7237 executables, not bin/ executables! Otherwise all the magic needed
7238 to find non installed files is turned off. This caused a failure
7239 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7240 as found in its environment (sent by tests/autoreconf): pointing
7241 to bin/autom4te that could not find its files.
7242 * tests/mktests.sh: Force the replacement of generated files, for
7243 the sake of "mv" program that are interactive when overwriting a
7245 * config/install-sh: Upgrade from CVS Automake.
7247 2003-09-23 Paul Eggert <eggert@twinsun.com>

7250 versus test -L issues.
7252 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and

7336 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7338 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7340 Add support for newer Fortran dialects. The F77 interface is
7341 unchanged, and continues to support Fortran 77. New FC macros
7342 correspond to all the old F77 macros, with output variables FC,
7343 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7344 available dialect, but older dialects can be specified. There are
7345 new macros AC_FC_SRCEXT to set the source extension, and
7346 AC_FC_FREEFORM to accept free-form source files.

7383 * tests/local.at: Require 2.57.
7384 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7385 are defaulted by AT_CHECK anyway.
7386 Use AT_CHECK_AUTOM4TE.

7462 Use &verb, not &verbose.
7464 2003-08-21 Akim Demaille <akim@epita.fr>
7466 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7468 ($help): Use Autom4te::ChannelDefs::usage.
7469 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7470 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7472 2003-08-21 Akim Demaille <akim@epita.fr>
7474 First stab at preserving warnings between calls to autom4te,
7475 including when the cache is used.
7477 There are still several issues: (i) there are too many runs of m4
7478 (one for include, one for warnings, and some more), (ii) warnings
7479 spreading on several lines are not handled gracefully, (iii) the
7480 code meant to have the call stack display for errors does not work
7481 (its handling should move from m4 to autom4te).
7483 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7485 (@preselect): Add m4_warn.
7486 ($exit_status): Remove, use $exit_code.
7487 ($help): Use Autom4te::ChannelDefs::usage.
7488 (&handle_m4): No longer define the m4_warnings.
7489 At each run, extract and report the warnings.
7490 Always cache the result, including if the exit status is on
7491 failure, since if nothing changes, we should result in the same
7492 failure, hence we can use the cache.
7493 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7494 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7496 (m4_warn): Redefine as a do-nothing: it is its invocation that
7497 matters, as warnings are now reported via traces.
7498 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7499 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7500 the latter reveals calls to the former.

7538 * bin/autom4te: Adjust.
7539 In particular, be Autoconf tools are really silent when properly
7540 working, bind the verbosity of the 'note' channel to $verbose.

7661 From Gareth McCaughan.
7663 2003-06-23 Akim Demaille <akim@epita.fr>
7665 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7666 not all of them. This fixes 1. the fact that when testing
7667 Autoconf there are many many config.log, 2. the incorrect use of
7668 top_srcdir to find config.log.
7669 Don't mix the detailed output of failed test with the summary of
7670 failures. Rather, append detailed log afterwards.
7672 2003-06-23 Akim Demaille <akim@epita.fr>
7674 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

7679 * tests/torture.at (#define header templates): Don't use quotes in

7748 is the inverse of localtime.

7757 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7759 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7760 Do not call `_exit()', simply modify `$?'.
7761 (xsystem): Reset $! before running system, and check it afterward.
7762 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7763 63 for version mismatches.
7765 2003-05-23 Akim Demaille <akim@epita.fr>
7767 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7768 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7769 the middle of a line).
7770 * lib/m4sugar/m4sugar.m4: Likewise.
7771 Remove useless spaces in comments.
7773 2003-05-23 Akim Demaille <akim@epita.fr>
7775 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

7777 difference with a plain failure.

7787 Paul Eggert <eggert@twinsun.com>
7789 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7790 Remove `#include <stdlib.h>' from the list; we should never
7791 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7792 resulting namespace pollution would cause other tests to fail.
7793 Configure scripts run with some older versions of g++ and HP's
7794 aCC would fail due to such an #include. Problems reported by
7795 Matthew Mueller in <http://bugs.debian.org/120704> and by
7797 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7798 In the test, use the test declaration before including <stdlib.h>,
7799 as that's closer to how it'll be used.
7801 2003-05-23 Akim Demaille <akim@epita.fr>
7803 * doc/autoconf.texi (Header Portability): ucred.h.
7806 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7808 Overhaul Autotest's logging: generate separate log files
7809 in testsuite.dir/NNN/testsuite.log, and append them to
7810 testsuite.log instead of re-running the test verbosely.
7812 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7813 file descriptor, write 0 to at_status_file instead of setting
7814 at_status=0, initialize some new variables (at_status_file,
7815 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7816 to rerun the tests, instead append the at_group_log to the
7817 at_suite_log when a test fails.
7818 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7819 with the AS_MESSAGE_LOG_FD redirected to stdout.
7820 (AT_CLEANUP): save the output status in $at_status_file
7821 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7823 (AT_CHECK): since tests are run with a redirected stdout,
7824 and used to be re-run in verbose mode, turn some $at_verbose
7825 into echo, and don't redirect the output of testing stdout
7828 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7829 the name of the debugging directory and information about

7944 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
7946 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
7949 2003-05-06 Akim Demaille <akim@epita.fr>
7951 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7952 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7953 by aclocal.m4 is changed it might require the importing of another
7954 m4 extension file, i.e., aclocal must be run.
7956 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7957 (&parse_args): Use --force with aclocal if required and supported.
7958 (&autoreconf_current_directory): Use &run_aclocal.

7965 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7966 argument instead of a file name, so that the request file remains
7967 open during the whole autom4te run.
7968 ($icache_file): New.
7969 (&freeze): Lock the $icache_file.
7971 2003-04-29 Derek Price <derek@ximbiot.com>
7973 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7974 seperator with m4_append_uniq(). It doesn't work.
7975 (AT_CLEANUP): Add `;' to end of at_help_all.
7976 (AT_INIT): Allow --keywords to be specified more than once. When
7977 grepping $at_help_all for keywords, use the field and keyword
7978 seperators to ensure a complete keyword match. Alter at_prev handling
7979 to support the new --keywords behavior.
7981 2003-04-27 Karl Berry <karl@freefriends.org>
7983 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7984 align better with others. I also made some of the individual
7985 entries on one line, for brevity and to make it easier for me to
7986 sort my dir-example file in the Texinfo distribution :).

8057 * tests/torture.at (Configuring subdirectories): Require aclocal
8058 1.4, otherwise the test fails, as it does support configure.ac.

8074 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
8075 use new diversions in preparation for accepting new arguments and
8076 allowing scripting around tests.
8077 (OPTIONS,TAIL): Remove these diversions to make way for the ones above.
8079 2003-03-26 Derek Price <derek@ximbiot.com>
8081 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of

8129 about `$<' in inference rules, it was a bogus interpretation of
8130 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
8131 Tru64 make in the "target lookup" section.
8132 (Automake): Automake 1.5+ no longer requires special tools to be
8133 present on the developer's host.
8135 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
8137 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
8138 to a shell that can handle redirection or quoting correctly.
8139 Override SHELL with the shell detected by configure.
8140 Use of $^O suggested by Tim van Holder.
8141 * bin/autom4te.in (BEGIN): Likewise.
8142 * bin/autoreconf.in (BEGIN): Likewise.
8143 * bin/autoscan.in (BEGIN): Likewise.

8173 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
8174 to fix a mismatch between example and discussion.
8176 2003-02-24 Kevin Ryde <user42@zip.com.au>
8178 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8179 format starting with "-".
8181 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

8188 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8189 compiler says yeah, but preproc says nope, compiler is right.
8190 Conversely, prompt the reader to send a bug report to the
8191 maintainers of the package, not of Autoconf.
8193 2003-02-20 Klee Dienes <kdienes@apple.com>
8195 * bin/autoreconf.in (autoreconf_current_directory): Properly
8196 handle an empty aclocal.m4.

8200 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
8204 2002-12-23 Paul Eggert <eggert@twinsun.com>
8206 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8207 innocuous variant befor including <limits.h> or <assert.h>. This
8208 works around a bug reported by Albert Chin: HP-UX 11i
8209 (and earlier versions) have a <limits.h> that declares
8210 gettimeofday and many other functions.
8212 2002-12-03 Paul Eggert <eggert@twinsun.com>
8216 * NEWS, configure.ac: Update version.
8218 * doc/fdl.texi: Upgrade to FDL version 1.2.
8220 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8221 nontrivially in main's body, so that f's external declaration is
8222 not optimized away in AIX. This should fix the bug reported by
8224 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8226 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8227 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8228 defined, to support freestanding compilers. This should fix the
8229 bug reported by Momchil Velkov in
8230 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8232 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8233 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
8234 obsolete AC_CHECK_TYPE. The missing empty arg was reported

8238 * Makefile.maint (www-gnu): New macro.
8239 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
8240 the location has moved.
8242 2002-12-02 Martin Frydl <martin@systinet.com>
8244 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
8245 \(.*\) match is too long and there is something more to be checked.
8246 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

8264 Update from masters.
8266 2002-11-14 Akim Demaille <akim@epita.fr>
8268 * Makefile.maint: Sync with Bison, i.e.:
8269 (po-check): Scan .l and .y files instead of the
8270 .c and the .h files that they generate. This fixes the bug
8271 reported by Tim Van Holder in:
8272 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8273 Look for N_ as well as for _. Try to avoid matching #define for
8277 2002-11-14 Akim Demaille <akim@epita.fr>
8279 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8280 From Paul Eggert and Albert Chin-A-Young.
8282 2002-11-14 Akim Demaille <akim@epita.fr>
8284 * doc/autoconf.texi (C Compiler): Solitary backslashes.
8285 From Paul Eggert and Albert Chin-A-Young.
8287 2002-11-14 Kevin Ryde <user42@zip.com.au>
8289 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8290 than assigning in main, to avoid HP cc +O3 optimizing it away.
8292 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8294 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8295 option. Process --recheck after parsing all options. Pass -q
8296 option to configure on --recheck.
8297 (AC_OUTPUT): Pass -q from configure to config.status.
8298 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8299 arguments to record.
8300 * doc/autoconf.texi (config.status Invocation): Document
8301 config.status -q option.
8303 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
8305 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
8306 Makefile.in if Makefile.am exists.

8328 Reported by Ezra Peisach.
8330 2002-11-05 Akim Demaille <akim@epita.fr>
8332 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8334 We _have_ to stop using the old compatibility scheme that tried to
8335 avoid useless backslashes because Libtool 1.4.3 contains a
8336 AC_DEFINE([error_t], [int],
8337 [Define to a type to use for \`error_t' if it is not
8338 otherwise available.])
8339 We _have_ to quote the single quote and backslashes with \. The
8340 old compatibility scheme saw that ` was backslashed, and therefore
8341 did not quote the single quote. Hence before this patch, Autoconf
8342 was not compatible with Libtool.
8344 2002-11-04 Paul Eggert <eggert@twinsun.com>
8346 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8387 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8388 Make variable, not a shell variable.
8389 Suggested by Bruno Haible.
8391 2002-10-31 Akim Demaille <akim@epita.fr>
8393 * bin/autom4te.in (load_configuration): Reject #args out of any
8396 2002-10-31 Akim Demaille <akim@epita.fr>

8399 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
8400 (_AC_RUN_IFELSE): Use it.
8401 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

8420 * doc/autoconf.texi (Header Templates): Put also in words what the

8422 (Customizing autom4te): s/--cache=/--cache /.
8424 2002-10-29 Akim Demaille <akim@epita.fr>
8426 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
8428 sparc_address_test returns void.
8429 Use it with an argument, as prototyped.
8432 2002-10-29 Akim Demaille <akim@epita.fr>
8434 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

8796 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8797 aclocal invocation, as Gettext macros might not be visible to

9051 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
9052 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9053 Reported by Ralf Corsepius.
9054 * tests/torture.at (Configuring subdirectories): Exercise these
9057 2002-09-09 Akim Demaille <akim@epita.fr>
9059 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
9060 looking for a replacement file.
9061 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9062 directory is relative.
9063 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9064 directory definition.
9065 Reported by Andreas Schwab and Jim Meyering.
9067 2002-09-06 Akim Demaille <akim@epita.fr>
9069 * doc/autoconf.texi (Setting Output Variables): Clarify what
9070 precious variables are.
9071 Suggested by Pontus Skoeld.
9073 2002-09-05 Akim Demaille <akim@epita.fr>
9075 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9076 (ifnames, autoscan, autom4te): Since we don't only depend on
9077 configure.ac variables (such as VERSION etc.), but also on prefix
9078 and so forth, depend on Makefile, not configure.ac.
9079 Reported by Alexandre Duret-Lutz.
9080 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9082 2002-09-05 Kevin Ryde <user42@zip.com.au>
9084 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9085 doesn't seem to be confined to ia64, just say "some versions".
9087 2002-09-04 Akim Demaille <akim@epita.fr>
9089 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9091 * Makefile.am (maintainer-clean-local): Remove.
9092 (MAINTAINERCLEANFILES): Remove COPYING.
9094 2002-09-03 Paul Eggert <eggert@twinsun.com>
9096 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9097 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9100 2002-09-03 Akim Demaille <akim@epita.fr>
9102 * configure.ac: Bump to 2.53d.
9103 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9104 as of today, on Automake's team suggestion.
9106 2002-09-03 Akim Demaille <akim@epita.fr>
9110 2002-09-02 Akim Demaille <akim@epita.fr>
9112 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9114 * configure.ac: Disable SITE_MACRO_DIR.
9116 2002-09-02 Jim Meyering <meyering@lucent.com>
9118 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9119 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9120 Also, tweak grammar: s/make sure to/be sure to/.
9122 2002-09-02 Paul Eggert <eggert@twinsun.com>
9124 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9125 directory names are generally preferable to physical names.
9127 2002-09-02 Akim Demaille <akim@epita.fr>
9129 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9130 Reported by Raja R. Harinath.
9131 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9132 * bin/autoupdate.in: Use error instead of die.
9134 2002-09-01 Paul Eggert <eggert@twinsun.com>
9136 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9137 ordinary shell concatenation rather than echo+tr+sed command that
9138 runs afoul of a long-line-related sed bug in Solaris 8.
9140 * bin/autoheader.in (parse_args): --warning -> --warnings.
9142 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9143 stdout, as traditional "ls" does.
9144 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9145 _AC_COMPILER_EXEEXT_O): Likewise.
9146 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9148 * bin/autoconf.as: Add --prepend-include option. This patch was
9149 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9150 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9152 * bin/autoconf.in, configure: Regenerate.
9154 * doc/autoconf.texi (Special Shell Variables): Mention
9155 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9157 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9158 MAILPATH and set PS1, PS2, PS4 to default values, to work
9159 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9160 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9161 the Autoconf documentation specifies; fall back to "unset" only if
9162 this fails. Use a shell for-loop for this rather than an m4 loop,
9163 to shorten the output script.
9165 2002-08-30 Paul Eggert <eggert@twinsun.com>
9167 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9168 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9169 for the CDPATH problem. Document PWD.
9170 (Limitations of Builtins): Document the problem that "cd $foo" and
9171 "ls $foo" may refer to different directories in shells conforming
9172 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9173 example, since the old example is now out of date.
9175 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9176 FOO" and "ls FOO" talk about different directories; this catches
9177 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9180 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9181 of rolling our own unset.
9182 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9183 in practice we needn't worry about CDPATH if unset doesn't work.
9185 * Makefile.in, aclocal.m4, bin/Makefile.in,
9186 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9187 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9188 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9189 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9190 tests/Makefile.in: Regenerate with Automake 1.6.3.
9192 * config/config.guess, config/config.sub, config/mkinstalldirs:
9195 * configure: Regenerate with self.
9197 2002-08-30 Kevin Ryde <user42@zip.com.au>

9207 2002-08-29 Akim Demaille <akim@epita.fr>
9209 * lib/Autom4te/General.pm (&xqx): New.
9210 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9211 hand, which is not portable.
9213 * bin/autom4te.in: Use them.
9214 Use &error instead of die.
9215 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9218 2002-08-17 Paul Eggert <eggert@twinsun.com>
9220 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9221 default list of compilers to try, since it was long ago superseded
9222 by the ksh fc builtin. Suggested by Steven G. Johnson.
9224 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9226 * doc/autoconf.texi (Invoking autom4te): End the option table,
9227 fixing a bug introduced by the previous patch.
9228 (Limitations of Make): Add a 'target lookup' subentry in the
9229 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9231 2002-07-29 Mark D. Roth <roth@feep.net>
9233 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9234 options and use $AUTOM4TE_PATH.
9235 * doc/autoconf.texi: Remove documentation of autom4te
9236 --include-envvar and --site-macro-subdir options and document
9237 use of $AUTOM4TE_PATH.
9238 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9239 arguments from each language section.
9241 2002-07-29 Paul Eggert <eggert@twinsun.com>
9243 * doc/install.texi: Include copyright symbol in copyright notice.
9245 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9247 (AM_MAKEINFOFLAGS): New macro.
9248 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9249 * Makefile.am (INSTALL): Use the new macros.
9250 Use -o rather than --output, since "missing" does not grok --output.
9252 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9254 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9255 comments do not always work. Never trust the exit status of
9258 2002-07-24 Kevin Ryde <user42@zip.com.au>
9260 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9261 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9263 2002-07-23 Paul Eggert <eggert@twinsun.com>
9265 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9266 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9267 apparently treats PATH="nonexistent" as if it contained ".".
9268 Bug reported by Stefan `Sec' Zehl.
9270 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9272 * doc/autoconf.texi (Limitations of Make): Mention the special

9544 Both macros now accept an optional source-dir arg.
9545 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9547 * NEWS: Document this.
9548 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9550 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9551 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9552 not for GNU extensions; this undoes part of the 2000-11-03 change,
9553 reverting to 2.13-compatible behavior.
9554 Add new optional argument DIR.
9555 (AC_FUNC_FNMATCH_GNU): New macro.
9557 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9559 2002-05-08 Paul Eggert <eggert@twinsun.com>
9561 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9562 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9563 and it causes a 'test' syntax error if it fails.
9564 Bug reported by Stephen Gildea.
9566 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9567 If prototypes are supported, use them to check this at compile-time,
9568 instead of trying to check it at run-time. If we must do a run-time
9569 check, assume that setvbuf is standard when cross-compiling, as
9570 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9571 Bug reported by Paul D. Smith.
9573 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9574 argument specifying location of getloadavg.c. This removes a
9575 FIXME. This idea was taken from Jim Meyering's implementation in
9577 * doc/autoconf.texi (Particular Functions): Document this.
9578 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9579 that's what the code does; this fixes a bug reported by
9582 2002-05-03 Akim Demaille <akim@epita.fr>
9584 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9585 autopoint instead of gettextize.
9586 ($uses_alocal): Rename as...
9587 ($uses_aclocal): this.
9588 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9589 Suggested by Bruno Haible.
9591 2002-05-03 Akim Demaille <akim@epita.fr>
9593 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9595 2002-04-29 Paul Eggert <eggert@twinsun.com>
9597 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9598 files to be 1 second older; just set them to be the same time.
9599 Also, sleep 1 second after the first aclocal, to work around
9600 problems with sub-second time stamps on the input files.
9602 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9604 * doc/autoconf.texi: Mention "set -e -x" lossage
9605 under node "Limitations of Builtins".
9607 2002-04-29 Akim Demaille <akim@epita.fr>
9609 * doc/install.texi: Better wording for setting variables when
9611 From Christian Cornelssen.
9613 2002-04-29 Akim Demaille <akim@epita.fr>
9615 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9616 of lack of $LINENO support, then the test will compare the $LINENO
9617 in testsuite vs. the lineno in the test file. This is wrong, of
9619 Be sure to protect it.
9620 Reported by Patrick Welche.
9622 2002-04-25 Akim Demaille <akim@epita.fr>
9624 * doc/autoconf.texi (Obsolete Macros): Typo.
9625 Reported by Vladimir Volovich.
9627 2002-04-25 Akim Demaille <akim@epita.fr>
9629 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9630 than some of the input files, hence, on the second run of aclocal,
9631 if some of its input are younger, make them older.
9632 Suggested by Paul Eggert.
9634 2002-04-25 Akim Demaille <akim@epita.fr>
9636 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9637 Thanks to Paul Eggert.
9639 2002-04-25 Akim Demaille <akim@epita.fr>
9641 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9642 and ac_subst_vars be sh variables containing the list of
9643 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9645 (_AC_INIT_PREPARE): Use them to log them.
9646 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9647 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9648 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9649 _AC_SUBST_FILES and _AC_SUBST_VARS.
9650 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9652 2002-04-24 Akim Demaille <akim@epita.fr>
9654 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9655 autoheader, so that automake does not complain about a missing
9656 config.h.in that was to be created.
9658 2002-04-23 Akim Demaille <akim@epita.fr>
9660 * bin/autoheader.in (parse_args): --warning takes an argument.
9663 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9665 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

9712 * doc/autoconf.texi: Follow the outline suggested in the GNU
9713 Sample Texts sections of the Texinfo 4.2 manual. Most
9714 importantly, this makes sure that the copyright notices appear in
9715 all output formats. You probably need Texinfo 4.2 to generate

9742 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9744 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9745 from aclocal.m4 too.

9754 workaround for ${1+"$@"}.
9755 * doc/autoconf.texi (Shell Substitutions): Explain it.
9756 From Oliver Kiddle and Peter Stephenson.
9758 Have M4sh perform minimal shell sanitizing.
9760 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9762 (_AS_PREPARE): this new macro.
9764 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9765 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9767 Adjust Autoconf and Autotest.
9769 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9770 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.

9778 * tests/wrapsh.as: New, precursor of wrapsh.in.
9779 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9780 on Autotest and M4sh.

9804 directories when descending in a SUBDIRS.

9807 2002-04-04 Andreas Schwab <schwab@suse.de>

9810 contains no literal separators.
9812 2002-04-03 Akim Demaille <akim@epita.fr>
9814 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)

9816 Use dnl, not the KILL diversion.
9818 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9819 (AC_CONFIG_LINKS): here.
9821 Don't use the KILL diversion, as it kills spurious output, which
9822 results in failures being hidden.
9823 Use m4_defn where appropriate.
9824 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9825 after the second argument.
9827 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9828 syntax, as it is provided by M4sugar.

9873 2002-03-27 Paul Eggert <eggert@twinsun.com>
9875 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

9899 2002-03-21 Paul Eggert <eggert@twinsun.com>
9901 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9902 problem with here-document buffer boundaries.
9904 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9905 when reinvoking the shell, to work around problems with installers
9906 who put strange things like "cd" commands in their environments.
9908 2002-03-19 Akim Demaille <akim@epita.fr>

9931 (Limitations of Usual Tools): Add mkdir section.
9933 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9934 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9935 back on AS_DIRNAME to compute prefixes otherwise; this is
9936 roughly what mkinstalldirs does. That way, we need not have
9937 our own filename disassembler. The old disassembler did not
9938 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9940 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9941 Create at_test_all by a series of assignments,
9942 not by a single assignment of a long string. The latter causes ksh
9943 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9944 presumably because of a buffer overrun.
9946 2002-03-14 Paul Eggert <eggert@twinsun.com>
9948 * lib/autotest/general.m4 (at_times_skip):
9949 Renamed from at_times. Now a boolean.
9950 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9951 says 'times: not found'.

10004 2002-03-08 Akim Demaille <akim@epita.fr>
10006 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
10007 because of C-c: have m4 output in tmp files, then mv them.
10009 2002-03-08 Akim Demaille <akim@epita.fr>

10032 message for LIBOBJ.
10034 2002-03-04 Akim Demaille <akim@epita.fr>

10041 * doc/autoconf.texi (Transforming Names): Equality between target
10042 and host is irrelevant.
10043 (Specifying Names, Canonicalizing): Remove all references to the
10044 backward compatibility hooks. Rather, collect them all into...
10045 (Hosts and Cross-Compilation): this new section.
10046 * doc/install.texi (System Type): Ditto.
10047 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
10048 that `--host' implies cross-compilation.
10050 2002-03-04 Akim Demaille <akim@epita.fr>
10052 * doc/autoconf.texi (Evaluation Macros): New.
10053 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10055 (_m4_foreach): Define the variant with immediate evaluation so
10056 that it contains exactly the items, not an expression which
10057 evaluation is the current item.
10058 (m4_re_string, m4_re_word): Don't over quote them.
10060 2002-03-04 Akim Demaille <akim@epita.fr>
10062 Instead of having stacking `shift's evaluated at the end, let
10063 `foreach' loops immediately evaluate them.
10065 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10066 $*. This is the n-th time I change my mind, but hopefully this is
10069 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10071 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10072 it was only a hack for m4_text_wrap.
10073 (m4_car2): Remove, replaced by...
10075 (_m4_foreach): Adjust.
10076 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10077 m4_bpatsubst for clarification.

10128 Fix Autoconf PR/207:
10129 AC_PREFIX_PROGRAM fails with dashed program names
10131 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
10132 variable when looking for the prefix program.
10133 Now it also works for shell variables.

10150 sure not to introduce newlines in at_groups.

10164 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
10165 cross-compilers, too. This undoes some of the most recent change
10168 2002-02-05 Akim Demaille <akim@epita.fr>
10170 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
10171 to make sure they are up to date when `check' is run.
10173 2002-02-05 Akim Demaille <akim@epita.fr>

10187 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
10188 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
10190 2002-02-05 Akim Demaille <akim@epita.fr>
10192 * bin/autom4te.in (&parse_args): Implement `frozen files are
10193 optional are the sum of the previous files on the command line'.
10194 Also, pass `--reload-state=' on them, so...
10195 (handle_m4): don't.
10196 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10197 (M4sh): Rely on M4sugar.

10235 2002-01-28 Akim Demaille <akim@epita.fr>
10237 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10238 AUTOTEST_PATH *after* it was set.
10239 Don't put `.' in the PATH: the user should be precise and `./' if
10240 needed. In addition, given that the test suite does some `cd', if
10241 `.' is in the path, the `tested programs' sections will report
10242 programs found in the test suite's directory, while during the
10243 tests (performed in their own directory), these programs are no
10244 longer visible. In other words, the results is confusing and
10246 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

10290 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10291 message on invalid options.
10292 * bin/autom4te.in (parse_args): Don't use
10293 Autoconf::General::getopt with non valid options.
10295 2002-01-17 Jim Meyering <meyering@lucent.com>
10297 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10298 $ac_cv_exeext so we don't use an old, invalid, cached value.
10300 2002-01-11 Akim Demaille <akim@epita.fr>

10312 package.m4, since is really depends upon configure.ac, not
10314 * doc/autoconf.texi (testsuite Scripts): Adjust.
10315 * tests/Makefile.am (package.m4): New.
10316 EXTRA_DIST it since its a source.
10318 2002-01-06 Akim Demaille <akim@epita.fr>
10320 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10321 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10322 and PACKAGE_BUGREPORT from here...
10323 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10325 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10326 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10327 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
10328 * tests/tools.at (autoheader): Adjust.
10329 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

10348 * doc/autoconf.texi (New Macros): Tweak wording.
10350 2001-12-14 Akim Demaille <akim@epita.fr>
10352 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10353 trailing files, don't apply `-rf' to files which might not be
10354 created by configure (core, core.*, and *.core), but just `rm -f'.
10355 Suggested by Jonathan Kamens.
10357 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10359 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

10369 abs_srcdir, top_srcpath to abs_top_srcdir.
10370 (_AC_OUTPUT_FILES): Adjust.

10381 2001-12-12 Kevin Ryde <user42@zip.com.au>
10383 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10384 forbidden file descriptors table.
10386 2001-11-26 Akim Demaille <akim@epita.fr>
10388 * bin/autoscan.in (%c_keywords): Build it at top level.
10389 Map to 1 in order to simplify its uses.
10391 2001-11-26 Akim Demaille <akim@epita.fr>
10393 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10394 Remove $filepath, useless.
10395 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10396 variables, they are really part of the tokens.
10397 Split the input line on spaces and then look for tokens.
10398 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10399 because of `lex$U.$(OBJEXT)'.
10400 (&scan_files): Use "@list" instead of join.
10401 * doc/Makefile.am (CLEANFILES): Add *.fns.
10403 2001-11-26 Akim Demaille <akim@epita.fr>

10406 Remove, replaced by...
10407 * tests/wrappl.in: Be common for all the Perl executables.
10408 In particular autoscan and autoheader want -I.
10409 * configure.ac: Adjust.
10410 * lib/autoscan/headers: errno.h is portable.
10412 2001-11-26 Akim Demaille <akim@epita.fr>
10414 * bin/autoscan.in (used): New.
10417 2001-11-26 Akim Demaille <akim@epita.fr>

10437 2001-11-26 Akim Demaille <akim@epita.fr>
10439 Test groups are now run two directories deeper.
10441 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10442 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10444 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10445 top_srcdir, builddir and top_builddir.
10446 Use `at_*dir' relatively to the directory containing the
10447 suite, use `*dir' when relatively to the current group dir.

10456 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10458 * doc/autoconf.texi (Using System Type): Add an example of `case
10459 $host' usage so people quit using `case $target' everywhere.
10461 2001-11-22 Akim Demaille <akim@epita.fr>
10463 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10464 spotted by Jim Meyering.
10466 2001-11-16 Paul Eggert <eggert@twinsun.com>
10468 This patch implements a `long double' suggestion by Oliver Kiddle.
10470 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10471 static, to catch errors if the value isn't known at compile-time
10472 and the compiler supports dynamic arrays. Change its name from
10473 `_array_' to `test_array' to avoid potential name clashes.
10474 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10475 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10476 better than double. Catch a bug in GCC 2.95.2 x86.
10477 * doc/autoconf.texi (C Compiler): Document the above.
10480 2001-11-13 Akim Demaille <akim@epita.fr>
10482 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10484 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10486 2001-11-13 Akim Demaille <akim@epita.fr>
10488 * lib/autotest/general.m4 (AT_INIT): After having run the test
10489 group, go back to the initial directory, not to at_suite_dir.
10491 2001-11-13 Akim Demaille <akim@epita.fr>
10493 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10494 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10495 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10497 (AT_CHECK_CONFIGURE): Use absolute paths.
10498 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10499 The problem is still the old one: there is no means in M4 (that I
10500 know about) to create a defining macro, because there is no means
10501 to create `$1' etc., therefore, the defining macro ``swallows''
10502 all the arguments meant to the defined macro.
10504 2001-11-13 Akim Demaille <akim@epita.fr>
10506 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10507 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in

10513 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10514 variable names when referring to a single test group, or to
10515 `suite' when referring to the whole test suite.
10516 `at_last_test' is removed: m4 compute at_format itself.
10517 (at_stdout, at_stder1, at_stderr): New variables.
10518 (AT_CHECK): Use them.
10520 2001-11-13 Akim Demaille <akim@epita.fr>
10522 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10524 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10525 Do it as soon as a test fails, don't wait till the end of the test
10527 Don't remove $as_me.[0-9]*, since these files no longer exist.
10529 2001-11-13 Akim Demaille <akim@epita.fr>
10531 * tests/tools.at: Use absolute paths, since we are no longer run
10534 2001-11-13 Akim Demaille <akim@epita.fr>
10536 Now that tests are running in their own private dir, there is no
10537 need to list the files to remove at the end of tests groups.
10539 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10540 (AT_data_files, at_data_files): Remove.
10541 (AT_CLEANUP, AT_DATA): Simplify.
10543 Remove the group dir if !debug && !failed.
10544 * tests/atspecific.m4: Adjust.
10546 2001-11-13 Akim Demaille <akim@epita.fr>
10548 Start a new layout for Autotest: `testsuite' creates
10549 `testsuite.dir' in which the at-check-line etc. files are to be
10550 found, and `testsuite.dir/003' where the test group 3 is run.
10552 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10553 at_check_line_file, at_format, at_test_normalized, at_group_dir
10555 Create the directories.
10556 Use absolute paths for at- files.
10557 (AT_CHECK): Adjust.
10559 2001-11-11 Michael Matz <matz@kde.org>
10561 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10563 (m4_car): Properly quote arguments.
10565 2001-11-13 Akim Demaille <akim@epita.fr>
10567 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10568 with stricter rules on LIBOBJS.

10572 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10573 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10576 2001-11-12 Akim Demaille <akim@epita.fr>
10578 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.

10585 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10586 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10587 specify to what the macro should be defined (typically to 1).

10594 2001-11-12 Akim Demaille <akim@epita.fr>
10596 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10597 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10598 definition used by Automake where LEX is +/- "${missing} lex" and
10599 `missing' itself contains variables.
10601 2001-11-12 Akim Demaille <akim@epita.fr>
10603 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10604 Now that M4sh pushes BODY, the comments were output at the end of
10607 2001-11-08 Akim Demaille <akim@epita.fr>
10609 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10610 that we can trace macros from aclocal.m4.
10611 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10612 obsoleted, and redirect to the former anyway.
10613 Reported by Ralf Corsepius.
10615 2001-11-08 Akim Demaille <akim@epita.fr>
10617 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10618 processed only if present.
10619 * tests/torture.at (Configuring subdirectories): Use autoreconf
10620 instead of successive calls to autoconf.
10621 Add a nonexistent subdirectory to exercise the patch above.
10622 Reported by Ralf Corsepius.
10624 2001-11-08 Kevin Ryde <user42@zip.com.au>
10626 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc

10646 ($(TESTSUITE)): this.
10649 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10651 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10652 the --prefix option, also remove it's argument.
10654 2001-11-05 Akim Demaille <akim@epita.fr>
10656 * doc/autoconf.texi (testsuite Invocation): Update.
10657 (Writing testsuite.at): Update.

10666 (&file_name_is_absolute): New, wrappers around routines from
10668 Use and export them.
10669 (&find_configure_ac): Optionally take a directory where to look at.
10670 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10672 Default @ARGV to `.', not find_configure_ac.
10673 (&autoreconf): Argument is a directory.
10674 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10675 * doc/autoconf.texi (autoreconf Invocation): Update.
10677 2001-11-03 Akim Demaille <akim@epita.fr>
10679 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10680 (@export_forward_subs): New.
10681 Add basename, dirname, and fileparse.
10683 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10684 Don't look for aclocal flags if we already know aclocal is not
10686 Move aclocal.m4t only if it exists.
10687 Reported by Ezra Peisach.
10689 2001-11-03 Akim Demaille <akim@epita.fr>
10691 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10692 passed on command line, defaulting to ./configure.ac if present.
10693 (&maybe_autoreconf, File::Find): Remove, unused.
10694 (&autoreconf): If autoconf is not used, don't try to trace.
10696 2001-11-02 Akim Demaille <akim@epita.fr>
10698 * configure.ac: Bump to 2.52g.
10700 2001-11-02 Akim Demaille <akim@epita.fr>
10704 2001-11-02 Akim Demaille <akim@epita.fr>
10706 * config/config.guess, config/config.sub, doc/standards.texi:
10707 * config/lispdir.m4: Update from masters.
10708 * configure.ac: Bump to 2.52f.
10710 2001-11-02 Akim Demaille <akim@epita.fr>

10717 2001-11-01 Paul Eggert <eggert@twinsun.com>
10719 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10720 be invoked before _AS_LINENO_PREPARE.
10721 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10722 than character ranges.
10724 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10725 invoking AS_BASENAME. Set the locale variables to 'C' if
10726 possible, as POSIX requires this to get the traditional
10728 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10730 2001-10-31 Paul Eggert <eggert@twinsun.com>
10732 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10733 with {}, as that triggers a bug in Bash 2.05.
10735 (_AS_LINENO_PREPARE): Use Sed rather than
10736 Awk. Fix the sed prepass to work even if there are multiple
10737 instances of $LINENO on the same line. Do not substitute for
10738 other variables like $LINENOT. Do not check file dates; such a
10739 check is unreliable on sufficiently fast machines, and removing
10740 the check makes the code simpler and more reliable. Check for
10741 output and chmod failures.
10743 * doc/autoconf.texi (Special Shell Variables): Document
10746 2001-10-31 Akim Demaille <akim@epita.fr>

10751 2001-10-31 Akim Demaille <akim@epita.fr>
10753 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10754 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10755 provided, while it is optional.
10756 * configure.ac: Adjust.
10758 2001-10-26 Paul Eggert <eggert@twinsun.com>
10760 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10761 lib/Autom4te/Struct.pm:
10762 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10765 * doc/autoconf.texi (Special Shell Variables): Document some
10766 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10768 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10769 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10770 eval $LINENO is not portable in practice.
10772 2001-10-24 Akim Demaille <akim@epita.fr>
10774 * lib/Autom4te/General.pm (backname): New.
10776 2001-10-24 Akim Demaille <akim@epita.fr>
10778 * m4/: Remove, merged into...

10783 * doc/autoconf.texi (Shellology): Mention the problems with bash
10784 2.05's use of ANSI quoting in its `set' builtin.
10786 2001-10-22 Paul Eggert <eggert@twinsun.com>
10788 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10789 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10790 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10791 POSIX decided to standardize on the int flavor of strerror_r.
10792 Always do char* test, as there's no reason not to.
10793 Assign to a char* var, to catch strerror_r that returns int*.
10795 * doc/autoconf.texi (Particular Functions):
10796 Document the above changes. Also, document the fact that
10797 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10799 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10801 2001-10-20 Akim Demaille <akim@epita.fr>
10803 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

10806 2001-10-20 Akim Demaille <akim@epita.fr>
10808 * lib/Autom4te/General.pm (&update_file): If destination is
10809 unchanged, remove the source.
10810 (&up_to_date_p): Don't be verbose, be debug.
10811 * bin/autoreconf.in: No longer support --m4dir.
10812 (&autoreconf): Display the full path of the configure.ac we are
10814 Trace it only once.
10815 Be sure to honor --force with gettextize.
10816 Always run aclocal.
10817 * doc/autoconf.texi: Adjust.
10819 2001-10-20 Akim Demaille <akim@epita.fr>
10821 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10823 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10824 `intl' is already present, as it refuses unless --force.
10825 (&parse_args): Use -I, --include instead of the old Autoconf
10827 ($localdir, $autoconf_dir): Remove.
10829 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10831 2001-10-19 Jens Petersen <petersen@redhat.com>
10833 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

10852 configure.ac being studied.
10854 2001-10-18 Paul Eggert <eggert@twinsun.com>
10856 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10857 long, to work around a bug in the HP C compiler version HP92453-01
10860 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10861 (AS_BASENAME_EXPR): New macro.
10862 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10863 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10864 and fall back on 'sed' only if the other two fail. This makes
10865 AS_BASENAME act more like AS_DIRNAME.
10866 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10867 contains white space.
10868 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10869 Use AS_DIRNAME, since I think it's now DOS-friendly.
10870 * tests/m4sh.at (DIRNAME_TEST): New arg $3.

10882 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
10883 m4_define, since...

11011 shell does not support LINENO, and if CONFIG_SHELL is unset or
11012 empty, and if we can find a shell that does support LINENO,
11013 then set CONFIG_SHELL to that shell and then re-execute
11014 ourselves with CONFIG_SHELL.
11016 2001-10-05 Paul Eggert <eggert@twinsun.com>
11018 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
11019 doesn't exist. Remove *.tmp, as a .tmp file is created during the

11061 compatibility with POSIX shells.
11063 2001-10-02 Akim Demaille <akim@epita.fr>
11065 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
11066 instead of exec'ing to preserve $0 and $@.

11101 and invoke a new argument $4 if either is discovered.
11102 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
11103 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

11182 Don't compute at_srcdir nor at_top_srcdir.
11184 * tests/tools.at: Hence use top_srcdir.
11186 * tests/Makefile.am, tests/autoconf, tests/autoheader,
11187 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:

11244 * tests/Makefile.am (package.m4): Remove.
11246 2001-09-22 Akim Demaille <akim@epita.fr>

11270 Suggested by Jim Meyering.
11272 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11274 * lib/autoconf/programs.m4: Use extensions listed in
11275 $ac_executable_extensions when looking for programs.

11319 2001-09-19 Akim Demaille <akim@epita.fr>
11321 * lib/autotest/general.m4: Englishoes.
11322 From Tim Van Holder and Alexey Mahotkin.
11324 2001-09-18 Paul Eggert <eggert@twinsun.com>
11326 * doc/autoconf.texi (Common Shell Constructs): New node,
11327 documenting AS_DIRNAME.
11328 (Limitations of Usual Tools): Refer to it when discussing dirname.
11329 Also, update discussion of POSIX standard to reflect latest draft.
11331 * lib/autoconf/c.m4:
11332 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11334 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11335 Do not pass a first argument with leading '-'
11336 to expr, by parenthesizing initial integers that might be negative.
11338 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11339 now merely checks whether it is an error to pass an argument
11342 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11343 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11344 whether it is a (compile-time) error to pass an argument to
11345 getpgrp. This simpler test supports the revised documentation,
11346 and is all that AC_FUNC_GETPGRP's users really need.
11348 2001-09-18 Akim Demaille <akim@epita.fr>
11350 * doc/autoconf.texi (Limitations of Make) <$<>: New.

11362 Add test for AS_BASENAME.
11363 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11364 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11365 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11366 * tests/base.at: Fixed the expected responses. The old ones were
11368 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11369 the documentation claims it should (and how it behaved in 2.13).
11371 2001-09-18 Akim Demaille <akim@epita.fr>
11373 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11374 the AC_CONFIG_COMMANDS invocation.
11375 This also solves the name clash problems.
11376 Don't set the package's ID.
11377 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11378 No longer to be shipped.
11379 (version.in): Remove.

11381 * lib/autoconf/status.m4: Adjust.
11382 Use `m4_PACKAGE_STRING'.
11383 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11384 the only optional argument is the name of the test suite.
11385 Expect `package.m4' to define the package signature.
11386 * lib/autom4te.in (Autotest): Add `package.m4?'.
11387 * tests/Makefile.am (package.m4): New.
11388 * tests/suite.at: ifnames is a victim.
11390 2001-09-18 Akim Demaille <akim@epita.fr>
11392 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11393 AC_LIBSOURCE, AC_CONFIG_FILES.
11394 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11395 program version string doesn't match the package's.
11396 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

11407 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11408 Always include <stdio.h> and <stdlib.h>. Evaluate
11409 the expression in an extra function before these includes. Call
11410 fprintf "%d" only after ensuring the argument is of type 'int'.
11411 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11413 2001-09-17 Paul Eggert <eggert@twinsun.com>
11415 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11416 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11417 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11418 when they don't exist.
11420 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11421 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11424 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11425 version with the version used by fileutils 4.1, except use
11426 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11429 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11431 2001-09-13 Akim Demaille <akim@epita.fr>

11469 2001-09-13 Akim Demaille <akim@epita.fr>
11471 * lib/autotest/general.m4 (AT_INIT): Create and remove
11472 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11473 test suites can cohabit.
11475 2001-09-13 Akim Demaille <akim@epita.fr>
11477 * tests/mktests.sh: Don't output banners for empty test files.

11576 to avoid GCC warnings.
11579 2001-09-05 Akim Demaille <akim@epita.fr>

11583 2001-09-05 Akim Demaille <akim@epita.fr>
11585 Be ready to handle filenames as stupid as `dnl.at', for if even
11586 the maintainer is dumb enough to do that...
11588 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11589 excellence in M4 quotation: consider `__file__' is active.
11591 And BTW, when invoking m4, pass the --include in the right order:

11622 New, extracted from main.
11623 Use IO::File wherever possible.

11654 2001-08-31 Akim Demaille <akim@epita.fr>
11656 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11657 (testsuite Scripts): There is no such thing as `atconfig.in'.
11658 And actually one diagram is missing: test suite runtime.

11662 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11665 2001-08-31 Akim Demaille <akim@epita.fr>
11667 * bin/autoupdate.in (@include): `installcheck' revealed the path
11668 to m4sugar was lacking!
11670 2001-08-31 Akim Demaille <akim@epita.fr>
11672 * man/Makefile.am (.x.1): We really have to pass

11684 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.

11728 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11729 `autoheader: `config.hin' is created'.
11730 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11732 2001-08-31 Akim Demaille <akim@epita.fr>

11740 Map --localdir, --autoconf-dir onto it.
11741 Forward autom4te's options instead of interpreting them.

11743 There is no such envvar since the inception of autom4te.cfg.

11765 * lib/Autom4te/General.pm (&find_peer): Remove.
11766 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11767 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11768 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11769 find the executables for it.
11770 * tests/Makefile.am: Major cleanup. Too lazy to document...
11771 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11773 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11774 indeed related to running the test suite, while passing
11775 --autoconf-dir and others is related to running non installed
11776 Autoconf executables. So don't do that, leave it to...

11778 * tests/autoscan: New.
11779 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

11796 Suggested by Paul Eggert.
11798 2001-08-29 Akim Demaille <akim@epita.fr>
11800 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11801 download in a tmp dir.
11803 2001-08-29 Akim Demaille <akim@epita.fr>
11805 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

11978 classified as an Autoconf macro.

12187 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

12205 * doc/autoconf.texi: Work around Texinfo buglets.
12206 (Transformation Rules): One example is enough, users are expected

12208 (dvar): New macro. Use it.
12210 2001-08-17 Akim Demaille <akim@epita.fr>
12212 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

12265 autom4te.cache (it's a directory, not a file.
12266 * Makefile.am: Ditto (but maintainer-clean-local).
12268 2001-08-15 Akim Demaille <akim@epita.fr>
12270 * bin/autom4te.in (@m4_warning): New.
12271 (&handle_m4): Use it.
12272 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

12280 don't waste time running `autoupdate --version' works.
12281 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
12283 2001-08-13 Akim Demaille <akim@epita.fr>

12344 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12345 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12346 * doc/autoconf.texi (C Compiler Characteristics): Update
12347 documentation for AC_C_BIGENDIAN.
12349 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12351 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12352 magic values from an object file when cross-compiling.
12353 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12355 2001-08-10 Akim Demaille <akim@epita.fr>
12357 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12359 Suggested by Russ Allbery.
12361 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12363 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12364 current $prefix to the sub-configures.
12366 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12368 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12369 extension (needed on BeOS). Reported by Guido van Rossum.

12373 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12375 2001-08-07 Akim Demaille <akim@epita.fr>
12377 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12379 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12380 No need to remove the files before and after the each test, before
12381 each test and at the end of the suite is enough.
12382 Display only the children `times', not the shell's.
12383 If the test failed or was skipped, at-times is not available.
12385 2001-08-07 Akim Demaille <akim@epita.fr>
12387 Always produce testsuite.log, including when there are no
12388 failures. This helps getting information on skipped tests, and
12389 duration of the tests. Err, implement the latter btw.
12391 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12392 Dump information on the first run of each test.
12393 (AT_CLEANUP): Create `at-times' containing the duration of the
12396 2001-08-07 Akim Demaille <akim@epita.fr>
12398 The use of `dumpstat' revealed that `len' was used although it
12399 should not. m4_text_wrap was using it, but in the Autoconf world
12400 where it is legal. Hence (i) test M4sh in its own world, not
12401 Autoconf's, and (ii), ahem, fix the bug :)
12403 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12404 does not like `' instead of [].
12405 (AT_INIT): Forbid `^_?AT_'.
12406 And don't output such tokens.
12407 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12408 `script.as', and `autom4te.cache'.
12409 Remove `empty' and `macro' which are no longer used.
12410 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12411 * tests/m4sugar.at: Use it.

12414 2001-08-07 Akim Demaille <akim@epita.fr>

12420 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
