47 string and then assume shell builtins like "test" will work.
49 2007-06-12 Noah Misch <noah@cs.caltech.edu>

193 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
194 for a.* when searching for executables, as this prevents users

207 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
208 AC_CHECK_TYPE, AC_CHECK_TYPES.
209 * doc/autoconf.texi (Generic types): C types must be type-names
210 (the C terminology), not type-ids (the C++ term). C++ types
211 must not be anonymous.

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

233 with objects too. Document the restrictions on its use.
234 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
235 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
236 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
237 works but the latter doesn't, then it's a valid type.
238 This lets people use function types and so forth.
239 For C++ there doesn't seem to be a simple solution, so leave it alone.
240 (AC_CHECK_SIZEOF): Allow argument to be a variable.
241 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
242 AC_CHECK_TYPE; that wasn't documented or necessary.

294 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
295 nonstandard grep R.E. escape sequences.
297 2007-03-17 Jim Meyering <jim@meyering.net>
299 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
300 (Limitations of Usual Tools): Also list \< and \>, and mention that
301 HP-UX's grep, like the one from Solaris, does not support that syntax.
303 2007-03-09 Stepan Kasal <kasal@ucw.cz>
305 * doc/autoconf.texi (Specifying Names): `--host' does not
306 change the build type.
308 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
310 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN

322 universal binaries. Problem reported by Elias Pipping.
324 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
326 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
327 * doc/autoconf.texi (C Compiler): Document this. There is a new
328 extra argument ACTION-IF-UNIVERSAL.

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

415 substitution will still be done by the special code.
416 Report by Jim Meyering.
418 * doc/autoconf.texi (File System Conventions): Mention that
419 $PATH_SEPARATOR is for the build system only.

440 early on the reader side, drop stderr of the input to avoid
441 `broken pipe' error output; this may happen even with shell
442 builtin `echo' of some bash versions. Reports by Ian Macdonald

482 * doc/autoconf.texi (Integer Overflow): Revised based on today's
483 feedback. The most important changes document what happens when

485 say that (sum < a) != (b < 0) reliably detects overflow when sum =
486 a + b.
488 * doc/autoconf.texi (Integer Overflow): Greatly expand and
489 rewrite, taking notions from the recent discussion on the gcc and
490 autoconf mailing lists; please see

502 support for AC_DEFINE-ing macros with arguments, and document
503 behavior when the same variable has multiple AC_DEFINEs.
504 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
505 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
506 macros directly, giving much shorter and simpler code.
508 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
510 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
511 space before "$ac_configure_args" to prevent a 'config.status
512 --recheck' failure if ac_configure_args doesn't contain a leading
513 space. This works around a problem with the XEmacs configure.ac,
514 which uses the (undocumented) ac_configure_args variable
515 inconsistently with Autoconf.
517 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
519 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
520 Include <limits.h>, and use its INT_MAX to rewrite the
521 j loop so that it does not overflow 'int'. Problem reported by
522 Ralf Wildenhues in
523 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
524 Play it safe by shifting left by 1 rather than multiplying by 2,
525 as GCC is less likely to optimize this away when the value
526 is signed (when it assumes overflow leads to undefined behavior).
527 Also, don't assume time_t uses two's complement.
529 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
531 * tests/torture.at (Substitute a 2000-byte string): Avoid using
532 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
533 dumps core on it. Report by Tim Rice.
535 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
537 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
538 --disable-option-checking to --help output even when
539 AC_PRESERVE_HELP_ORDER is not used.
540 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
541 --with argument, rather than argument with [-.] replaced by
542 underscores.
543 * NEWS: Fix typo in previous change; the news was in the
544 wrong section.
546 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
548 * NEWS: Warnings are now generated by default for unknown
549 --enable-* and --with-* options.
550 * doc/autoconf.texi (Option Checking): Renamed from
551 (Configure Option Checking). Tighten up the wording a bit.
552 (External Software, Package Options): Cross-reference to Option
553 Checking, and use this to shorten our section.
554 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
555 "$x" to test "x$foo" != x.
556 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
557 Don't warn if $enable_option_checking is "no".
558 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
559 ac_unrecognized_opts to the empty string.
560 Don't echo the unrecognized opts, as this might mishandle
561 backslashes or leading -.
562 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
563 usage next to the other --disable-FEATURE options in the
564 help string.
566 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
568 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
569 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
570 Print warning for unrecognized --with and --enable options
571 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
572 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
573 Disable option checking when subdirs are configured.
574 (AC_OUTPUT): If warnings are enabled, print warning about
575 unrecognized --with and --enable options at the end of
576 the configure output (as well as at the beginning).
577 * doc/autoconf.texi (Option Checking): New node.
578 Document new option warning functionality.
580 2006-12-16 Eric Blake <ebb9@byu.net>
582 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
583 * NEWS: Start news for current version.
585 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
587 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
588 Define HAVE_GETMNTENT to 1, not to the empty string.
589 Problem originally reported by Jochen Friedrich in
590 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
592 This change prompted by a problem report by Andrey Simonenko in
593 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
594 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
595 object-like macros only, in the traditional portable character
596 set.
597 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
598 Warn about attempts to define things that are not identifiers.
599 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
600 awful hack that AC_DEFINEd macro names containing parentheses.
602 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
604 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
605 too drastic, even if Texinfo in theory requires it for info mode.
607 (config.status Invocation): Renamed back from Recreating a
608 Configuration).
609 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
610 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
612 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
614 * NEWS: Version 2.61a.
616 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
617 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
619 * NEWS: Document changes with echo and printf, and the lack
620 of limits on the total size of multi-line values of substituted
621 variables, and the AC_FUNC_FSEEKO fix.
623 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
625 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
626 Writing configure.ac.
627 (Autoconf Input Layout): Renamed from configure.ac Layout.
628 (Recreating a Configuration): Renamed from config.status Invocation.
629 (Obsolete Recreation): Renamed from Obsolete config.status Use.
630 (acconfig Header): Renamed from acconfig.h.
631 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
632 (Writing Testsuites): Renamed from Writing testsuite.at.
633 (Autom4te Cache): Renamed from autom4te.cache.
635 * BUGS: Remove mention of VPATH problem, since it's now documented
636 not to be a bug in the Autoconf build procedure itself, but rather
637 a problem with the proprietary `make' programs.
639 * doc/autoconf.texi (Build Directories): Add a cross reference
640 to VPATH and Make.
642 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
643 * doc/standards.texi: Sync from gnulib.
645 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
646 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
647 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
648 generated automatically.
650 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
652 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
653 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
654 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
656 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
658 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
659 `CEOF$ac_eof' special marker, the awk script cannot contain a
660 line matching `^CEOF', so this is not needed any more.
661 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
662 special marker in the test.
664 2006-12-06 Stepan Kasal <kasal@ucw.cz>
666 * tests/tools.at (autom4te preselections): Use `find -newer';
667 remove one of the sleeps.
669 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
670 more readable, using ...
671 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
673 * doc/autoconf.texi (autoheader Invocation): Do not double-
674 quote the parameter of `AH_BOTTOM' in the example.
676 2006-12-05 Stepan Kasal <kasal@ucw.cz>
678 * doc/autoconf.texi (Configuration Headers): Remove the
679 example with multiple input files.
680 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
681 multiple input files.
683 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
685 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
686 creating the awk substitution script, handle one input line at a
687 time, so that the maximum length of a substituted (multi-line)
688 value is not limited by the size of the sed pattern space.
689 The trade-off is a slightly repetitive sed script.
690 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
691 can only have up to 7 characters, due to Solaris 10 /bin/sed.
692 * tests/torture.at (Substitute a 2000-byte string): Increase the
693 test with several long lines, they should not be caught by sed
694 limits any more.
696 * tests/tools.at (autom4te preselections): New test, to flag
697 entries missing from autom4te.cfg.
698 Report by David Byron <dbyron@hheld.com>.
700 * tests/torture.at (Substitute a 2000-byte string): Actually use
701 AC_PROG_AWK, so the last change works as intended.
702 (Substitute and define special characters): Likewise.
703 (Substitute a newline): Likewise.
705 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
706 instead of `awk' consistently.
707 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
708 * tests/torture.at (Torturing config.status): Test both the
709 result of AC_PROG_AWK and plain awk.
710 (Substitute a 2000-byte string): Likewise.
711 (Substitute and define special characters): Likewise.
712 (Substitute a newline): Likewise.
714 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
716 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
717 can be assigned to a function pointer. Problem reported by
718 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
719 part of a patch by Ralf Wildenhues in that same bug report.
721 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
723 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
724 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
726 2006-12-01 Eric Blake <ebb9@byu.net>
728 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
729 cross-compiling from cygwin to mingw.
730 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
731 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
732 to lib/autoconf/c.m4.
734 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
736 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
737 string for more reliable failure. Wrap the entire test that
738 causes the broken Solaris printf to dump core, in a subshell,
739 so the segmentation fault message is reliably suppressed.
740 Fix shell expansion errors by using /usr/ucb/echo always;
741 avoid an error on systems without it by another subshell.
742 Avoid m4 expansion of `$1'. Set the zeroth argument of the
743 subshell-$as_echo to `as_echo', for better error message.
745 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
747 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
748 `BASH_SOURCE' contain a newline, set them to empty, as they may
749 not be unset.
751 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
753 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
754 years and is too hard to maintain now. The last straw was
755 reported by Jerker Baeck in
756 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
757 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
758 * doc/autoconf.texi (Particular Functions): Move
759 AC_FUNC_SETVBUF_REVERSED from here...
760 (Obsolete Macros): ... to here. Say that it does nothing now.
761 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
762 Turn into (almost) a no-op.
764 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
765 (AC_C_VOLATILE):
766 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
767 These macros are obsolescent and new applications shouldn't need them.
768 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
769 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
770 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
771 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
772 (AC_FUNC_VPRINTF): Likewise.
773 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
774 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
775 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
777 * doc/autoconf.texi (Setting Output Variables): Mention that
778 @VAR1@VAR2 has unspecified behavior. Problem reported by
779 Ralf Wildenhues.
780 * NEWS: Mention this.
782 * Makefile.am: Put only a single '#' into the copyright notice,
783 so that it's also present in the output file. Standardize wording
784 in makefile copyright notices to match GNU coding standards.
785 * bin/Makefile.am: Likewise.
786 * doc/Makefile.am: Likewise.
787 * lib/Makefile.am: Likewise.
788 * lib/freeze.mk: Likewise.
789 * lib/autoconf/Makefile.am: Likewise.
790 * lib/autoscan/Makefile.am: Likewise.
791 * lib/autotest/Makefile.am: Likewise.
792 * lib/m4sugar/Makefile.am: Likewise.
793 * man/Makefile.am: Likewise.
794 * tests/Makefile.am: Likewise.
795 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
796 one-line file.
798 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
800 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
801 in the sed script that mangles the awk script: delete up to the
802 first exclamation mark only.
803 * tests/torture.at (Substitute and define special characters):
804 Test '!' too.
806 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
808 Rewrite config files generation: avoid quadratic growth in
809 the number of substituted variables by using awk instead of sed
810 for the bulk of the substitutions.
811 * NEWS: Mention this.
812 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
813 forbidden in the output (and thus input) file.
814 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
815 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
816 generate just one large awk script for substitutions,
817 eliminating much of the earlier complexity, while adding some
818 new complexity. Only expand the substitution templates at
819 configure time, for smaller configure script size. If
820 _AC_SUBST_FILES are used, test 'awk' for working getline support
821 at config.status time. If absent, interpolate through the
822 shell. The awk script was written with much help
823 from Paolo Bonzini and Paul Eggert.
824 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
825 (_AC_SED_FRAG_NUM): Likewise.
826 (_AC_SUBST_CMDS): Renamed from...
827 (_AC_SED_CMDS): ...this.
828 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
829 * tests/torture.at (Substitute a 2000-byte string): Also
830 substitute a line with 1000 words, and a variable with several
831 long lines.
832 (Substitute and define special characters): Test awk special
833 characters, and put substitution input strings `@foo@' in the
834 output, to test that no recursion happens; test several other
835 combinations from Paolo Bonzini.
837 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
839 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
840 that replaced echo with AS_ECHO where this wasn't necessary.
841 Problem reportd by Ralf Wildenhues.
842 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
843 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
844 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
846 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
848 * lib/freeze.mk (GREP): Removed, no need to initialize this.
850 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
852 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
853 that traditional Awk lacks 3-arg "split". It has it.
854 Mention that FS must be a single character, and a few other
855 99-byte limits of traditional Awk.
856 Mention that if (i in a) doesn't work with traditional Awk.
858 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
860 * tests/autotest.at (BSx641-newline in command):
861 (BS-BS-newline in command, BSx640-newline in command):
862 (Newline-CODE-BS-newline in command):
863 (Single-quote-BS-newline in command):
864 (Single-quote-newline-BS-newline in command):
865 Use printf '%s\n' instead of echo, for portability to hosts
866 where echo interprets backslashes. This will break on hosts
867 that lack printf, but for now let's assume all such hosts
868 are dead (if not, we should get reports of test failures).
870 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
872 'echo' has some portability problems, when given a first argument
873 with a leading '-', or when given any argument containing '\'.
874 Avoid using 'echo' in these cases.
875 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
876 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
877 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
878 * lib/autotest/general.m4 (AT_INIT): Likewise.
879 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
880 argument might be unportable.

898 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
899 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
900 * bin/autoconf.as: Redo verbose flag implementation, as the old
901 scheme wouldn't work with AS_ECHO.
902 * lib/autotest/general.m4 (AT_INIT): Likewise.
903 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
904 Don't use ECHO_T, since ECHO_N is now reliable.
905 * lib/autotest/general.m4 (AT_INIT): Likewise.
906 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
907 rather than using a here-document to put the script into a file.
908 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
909 use AS_ECHO.
910 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
911 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
912 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
913 bug, but we might as well stop using ECHO_N and ECHO_C internally.
914 * lib/autotest/general.m4 (AT_SETUP): Likewise.
915 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
916 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
917 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
918 operand, as AS_ECHO requires. Avoid double file name expansion.
919 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
920 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
921 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
922 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
923 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
924 Double-quote strings that would otherwise contain M4 comments.
925 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
927 * configure.ac (AC_INIT): Bump to 2.61a.
928 * NEWS: Likewise.
930 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
932 Version 2.61.
934 * configure.ac (AC_INIT): Bump to 2.61.
935 * NEWS: Likewise.
937 * tests/autotest.at (Macro with backslash in a test title):
938 Comment out for now, as this tests neither fails nor passes
939 reliably. Problem reported by Ralf Wildenhues.
941 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
943 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

1031 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set

1037 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

1064 Single-quote in a test title,
1065 Double-quote in a test title): Don't expect failure anymore.
1066 (Backslash in a test title): Put a non-whitespace character after the
1067 backslash so that Bourne shells might actually see it as an escape
1068 sequence.
1069 (Brackets in a test title,
1070 Pound in a test title,

1072 Quoted Macro in a test title,

1079 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
1080 The visible effect was a stray [] in the testsuite output.
1082 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1084 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
1085 `trap ... 0' inside a function, for AIX sh.
1087 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1089 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1090 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1091 5363) simply issues a warning when dividing by zero at compile
1092 time. Problem reported by Elias Pipping.
1094 2006-10-26 Eric Blake <ebb9@byu.net>
1096 * THANKS: Update.
1097 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1098 show effect on macros that expand with commas.
1099 Reported by Joel E. Denny.
1101 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

1123 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
1125 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1126 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1127 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1128 reported by Nelson H. F. Beebe for Coreutils 6.4.
1130 * tests/tools.at (autoconf --trace: user macros): Remove test
1131 for tracing multiline macros, since m4 1.4.7a uses a different
1132 way to number lines. Problem reported by Ralf Wildenhues.
1134 2006-10-24 Stepan Kasal <kasal@ucw.cz>
1136 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1137 /dev/null since the heuristics for interactive behaviour was
1138 fixed in CVS m4.
1140 * bin/autom4te.in: With --force, always refresh the output
1141 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

1162 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1163 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
1165 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1191 2006-10-14 Stepan Kasal <kasal@ucw.cz>
1193 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
1194 looking for special shell characters.
1195 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
1196 macro defined by AS_VAR_PUSHDEF before passing it as a
1197 parameter.
1198 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
1199 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

1208 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1210 (Imported from Automake.)
1211 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1212 which incorrectly sets the mode of an existing destination
1213 directory. In some cases the unpatched install-sh could do the
1214 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1215 system. We hope this is rare in practice, but it's clearly worth
1216 fixing. Problem reported by Alex Unleashed in
1217 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1218 Also, don't bother to check for -m bugs unless we're using -m;
1219 suggested by Stepan Kasal.
1221 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>

1227 is enabled by default with gnu and gnits strictness.
1228 Report from Bruno Haible.
1230 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
1231 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
1232 gnu and gnits modes.
1234 Import this change from Config:
1236 2006-09-20 Ben Elliston <bje@gnu.org>

1239 Import this change from Gnulib:
1241 2006-09-16 Karl Berry <karl@gnu.org>
1242 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
1243 to avoid sectioning errors.
1245 Import these changes from Texinfo:
1247 2006-10-04 Karl Berry <karl@gnu.org>
1248 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

1252 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
1253 (\code): must use new \...Char values, since now ` is active.
1255 2006-08-26 Karl Berry <karl@gnu.org>
1256 * build-aux/texinfo.tex (\textdegree): New command.
1258 2006-08-12 Karl Berry <karl@gnu.org>
1259 * build-aux/texinfo.tex (error \box0): smaller font.

1263 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
1265 2006-10-13 Stepan Kasal <kasal@ucw.cz>
1267 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1268 added to the template can get mangled.
1270 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1272 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1273 include the default headers, and redefine obstack_chunk_alloc
1274 and obstack_chunk_free. Fixes false failure with glibc.
1276 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1278 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
1279 for backward compatibility with Libtool 1.5.22. Problem reported
1280 by Ralf Wildenhues.
1282 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1284 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
1285 AC_PROG_CC.

1288 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1290 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
1291 the NonStop platform.

1293 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1295 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1296 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1297 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1298 Use a better substitute, by inspecting the output of "ls"
1299 rather than just using ":".
1300 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1301 rather than AS_EXECUTABLE_P, since we needn't worry about
1302 non-regular files here.
1304 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1305 due to configuration hassles with this. See Tonya Underwood's report
1306 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1307 * doc/autoconf.texi (Special Shell Variables): Likewise.

1310 Stepan Kasal <kasal@ucw.cz>

1315 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1317 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1318 initialization which is not inherited through the environment
1319 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1320 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1322 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1324 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1325 problems with mkdir -p -m.
1327 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1329 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1330 comment about ac_cpp_err; it was incorrect, and anyway
1331 ac_cpp_err is being removed below.
1332 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1333 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1334 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1335 nobody uses it.
1336 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1337 with werror_flag and conftest.err and so forth. This is more
1338 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1339 and anyway the user shouldn't normally want to see this gorp logged.
1340 Problem reported by Ralf Wildenhues.
1341 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1342 empty, not 'no', since the rest of the code uses 'test -z'.
1344 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1346 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1347 Use a single call to AC_DO_TOKENS rather than multiple, for
1348 efficiency.
1349 (_AC_LINK_IFELSE): Test that resulting file is executable.
1350 Problem reported by mwoehlke in
1351 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1353 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1354 than creating a file to use with test -x; this is much faster.
1356 2006-10-02 Bruno Haible <bruno@clisp.org>
1358 * lib/autom4te.in (Automake-preselections): Add
1359 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1361 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1363 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1364 standard error, `experr' should be used, not `expout'.
1366 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1368 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1369 fseeko testing program twice; just use the earlier result.
1370 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1371 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1372 still doesn't let the program compile.
1373 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1374 failed.
1376 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1377 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1378 include it, without including anything else.
1379 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1380 expressions.
1381 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1383 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1385 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1386 `error.h', and include it, for a `error_at_line' prototype.
1387 Use a nonempty format string in the link test.
1388 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1389 for a declaration of wait3.

1393 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1394 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1395 can apply to constants too, and that it checks for macro defns.
1396 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1397 and simply cast the identifier to void. This handles structure
1398 values. Problem reported by Ralf Wildenhues.
1399 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1401 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1510 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1511 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now

1534 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1535 f90/f95 because the latter drivers of AIX Fortran 9.1 do not

1610 deal with LEXLIB.
1611 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1612 didn't work if some values were cached but not others. Test for
1613 broken lex libraries like native ia64-hp-hpux11.22; see
1614 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1615 work around the problem by preferring an empty LEXLIB to -lfl or
1616 -ll. Let the user set LEXLIB='' to indicate no library needed.
1618 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1619 * README: Likewise.

1855 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1857 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
1858 (_AC_COMPUTE_INT): Add obsoletion warnings.
1859 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
1860 AC_COMPUTE_INT.
1862 * NEWS: Document change.
1864 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1866 * doc/autoconf.texi (Volatile Objects): New section.
1868 * NEWS: Document previous change.
1870 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1872 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1873 Require that long long int be at least 64 bits wide. C99 requires
1874 this and enough programs depend on it so we should check for it.
1875 Bruno Haible reports in
1876 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1877 that long long int is 32 bits wide with some nonstandard compilers.
1878 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1880 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1882 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1883 to a nonexistent file, so that we don't have to worry about
1884 a local site configuration that doesn't use /usr/local.
1885 Problem reported by Keith Marshall in
1886 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1888 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1890 * doc/autoconf.texi: Be more consistent about using @acronym with
1891 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1892 quite right (it talked about "OSF/Tru64", even though the
1893 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1894 and it even mentioned "OSF 4"!) and at this point there's little
1895 reason to talk about OSF any more, since it died in 1994.
1896 (Specific Compiler Characteristics): Simplify example of
1897 negative-size array.
1898 (File Descriptors): Reorder to make the text flow better.
1899 Remove joke about "appreciate the various levels"; I didn't get it.
1900 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1901 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1902 (File Descriptors, Limitations of Usual Tools):
1903 Tone down the advice against renaming or removing open files.
1904 (Limitations of Usual Tools): Add a new section, on 'rm'.
1906 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1908 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1909 -lXt in LIBS, idea from Karsten Hopp; this was due since
1910 this change:
1912 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1913 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1914 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1915 (which belong to Xt, not X itself). See Debian bug 327655.
1917 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1919 * configure.ac (AC_INIT): Bump to 2.60a.
1920 * NEWS: Update.
1922 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1924 Version 2.60.
1926 * configure.ac, NEWS: Update.
1928 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1930 * config/texinfo.tex: Sync from upstream.
1932 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1933 quadrigraph correctly in traces.
1935 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1936 Fix typos.
1938 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1939 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1940 not defined.
1941 * doc/autoconf.texi (Changed Directory Variables): New node,
1942 to document the whole `datarootdir' business a bit better.
1943 * NEWS: Update.
1944 * tests/torture.at (datarootdir workaround): Extend test.
1945 Prompted by report by Alexandre Julliard.
1947 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1949 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1950 when using default mode of IBM C 6 for AIX. Problem and two-line
1951 fix reported by Larry Jones.
1953 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1955 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1956 about literal '${datarootdir}' if a definition is found in the
1957 output file.
1959 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1961 * NEWS: Use "M4" rather than "m4" when appropriate.
1962 Problem reported by Eric Blake.
1963 * doc/autoconf.texi: Likewise.
1964 Use @acronym around BSD, GCC, and GNU when appropriate.
1965 (Why GNU M4): Renamed from "Why GNU m4".
1966 (Redefined M4 Macros): Mention that Posix
1967 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1968 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1969 to int.
1971 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1973 * bin/autom4te.in (handle_output): Do not forbid the empty
1974 pattern.
1975 * tests/tools.at (autoconf: the empty token): New test.
1977 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1979 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1980 calls, so that we do not care whether they are LIFO or FIFO;
1981 in the m4_wrap, do not check which diversion is the topmost
1982 one, just check that the stack is balanced at the end.
1983 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1984 base diversion forever--pop the previous diversion before
1985 opening the new one; consequently, remove the m4_wrap call.
1986 * lib/autotest/general.m4 (AT_INIT): Likewise.
1987 * tests/m4sugar.at: Do not use
1988 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1990 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1991 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1993 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1994 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1995 Rework example of m4wrap token-pasting trouble so that it doesn't
1996 care whether it's LIFO or FIFO.
1997 Fix some "contrary to"s that are awkward in English.
1999 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2001 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
2002 to `yes' instead of `int$1_t' if the type is found, for more
2003 consistent configure output (where $1 is the number of bits).
2004 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
2005 Suggested by Bruno Haible.
2007 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
2008 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
2009 with system headers. Report by Bruno Haible.
2011 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2013 * config/config.guess, config/config.sub: Sync from upstream.
2015 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2016 in order to avoid picking up an older installed frozen m4sh.m4f.
2017 Besides an outdated shell startup, this could have been created
2018 by an earlier M4 version with incompatible frozen file format.
2020 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2022 * README: Recommend m4 1.4.4 instead of 1.4.3..
2023 * doc/autoconf.texi: Likewise.
2024 (Special Chars in Names): Say that $(.FOO) is portable, as
2025 suggested by Stepan Kasal.
2026 (Installation Directory Variables, Build Directories):
2027 (Automatic Remaking, Subdirectories, Fortran Compiler):
2028 (Making testsuite Scripts, Defining Directories):
2029 Quote variable usages better.
2030 (Making testsuite Scripts): Add clean-local rule to makefile
2031 snippet, by Eric Blake.
2032 (Installation Directory Variables): Fix table item font.
2033 Reword slightly to clarify. Generalize advice about
2034 not using special characters to include all file-related
2035 vars, not just VPATH.
2036 (Special Chars in Variables): Warn about special characters in
2037 $(srcdir) too.
2038 (Assignments): Clarify default-value example as suggested by
2039 Ralf Wildenhues in
2040 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2041 (Special Shell Variables): Note leading ./ or ../, as suggested
2042 by Eric Blake.
2043 (Limitations of Builtins): Under cd, warn about CDPATH.
2044 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2045 Ralf Wildenhues.
2047 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2049 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2050 `@var', for texi2html.
2051 (Systemology): Some more word wrapping, for DVI output.
2052 (autom4te Invocation): The short option for `--melt' is `-M',
2053 not `-m'.
2055 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2057 * doc/autoconf.texi: More formatting and English tweaks,
2058 many suggested by Ralf Wildenhues.
2059 Reword to avoid "@code{...}'s" and the like, since it's ugly
2060 with Emacs info mode. discontents -> woes.
2061 Put a few "will"s back. time stamp -> timestamp.
2062 side-effect -> side effect.
2064 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2066 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2067 Warn about $@ not persisting. Problem reported by Julien Danjou in
2068 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2069 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2070 Mention other special chars, too.
2072 2006-06-14 Eric Blake <ebb9@byu.net>
2074 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2076 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2078 * doc/autoconf.texi: Some systematic minor improvements, as
2079 follows. Use "makefile" when talking about makefiles
2080 generally (which might be named "makefile" or "Makefile" or even
2081 "foo.mk"), "Makefile" when talking about a specific makefile
2082 called "Makefile". This unclutters the text from weird quotes
2083 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2084 values" rather than "@var{foo}s" and similar constructs containing
2085 "}s". Use "Make rules" rather than "Makefile rules". Minor
2086 English-language improvements. Change the prefix "sub-" to "sub"
2087 and "re-" to "re".
2088 Put blank lines around examples more consistently.
2089 Avoid "rather" and "very" as intensifiers.
2090 Avoid "will" as an auxiliary.
2091 (Limitations of Make): Split this node into....
2092 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2093 (Leading _ in Macro Names, Backslash-Newline-Newline):
2094 (Backslash-Newline Comments, Long Lines in Makefiles):
2095 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2096 (obj/ and Make, make -k Status, VPATH and Make):
2097 (VPATH and Double-colon, $< in Explicit Rules):
2098 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2099 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2100 New nodes, resulting from splitup of Limitations of Make.
2101 All cross-references changed. Raise the top node from
2102 a section to a chapter, and all subnodes accordingly.
2103 Redo the introductory wording to match the new organization.
2104 (Installation Directory Variables): Use an example that is
2105 closer to what Autoconf actually does. Mention that VPATH's
2106 value should not contain metacharacters or white space.
2107 (Fortran Compiler): Fix a VPATH bug in an example.
2108 (Leading _ in Macro Names): Mention that this problem is no longer
2109 of practical concern.
2110 (VPATH and Make): Reword the advice to make it clearer
2111 that Autoconf and Automake support VPATH in non-GNU make, but
2112 many packages have bugs in this area.
2113 ($< in Explicit Rules): Refer to Build Directories rather
2114 than using a (non-VPATH-safe) example.
2115 (Automatic Rule Rewriting): Mention the sort of disaster that
2116 can ensue with Solaris-style rule rewriting with VPATH.
2118 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2120 * doc/install.texi (Compilers and Options): Weaken the
2121 suggestion to use GNU make for VPATH builds.
2123 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2124 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2126 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2127 in regular expression.
2129 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2131 * doc/autoconf.texi (Installation Directory Variables):
2132 Drop extra @samp from `@table @samp' item.
2133 (Limitations of Usual Tools): Comment fix.
2134 Do not nest @samp just to point to other table items.
2135 (Writing testsuite.at) <AT_CHECK>: The second argument to
2136 `@dvar' is already @samp'ed.
2137 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2138 do not use @var in the second argument.
2140 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2142 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2143 $as_shell.exe too. Problem reported by Andreas Buening in
2144 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2146 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2148 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2149 `unused variable' compiler warning, for `-Wall -Werror'.
2150 Reported by Jaap Haitsma in
2151 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2153 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2155 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2156 case the compiler dumps core. Problem reported for
2157 OpenServer 5.0.7 by Tim Rice in
2158 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2159 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2160 Likewise.
2162 2006-06-06 Tim Rice <tim@multitalents.net>.
2164 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2165 "ERROR" only shows up in "make check" output if there is an
2166 error.
2168 2006-06-06 Eric Blake <ebb9@byu.net>
2170 * tests/tools.at (automatically allowed tokens): Fix typo.
2172 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2174 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2176 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2177 typically overflows on x86 CPUs, even though the C standard
2178 requires otherwise.
2180 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2182 * configure.ac (AC_INIT): Bump to 2.59e.
2183 * NEWS: Update.
2185 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2187 Version 2.59d.
2189 * config/texinfo.tex: Sync from upstream.
2191 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2192 seen, invoke libtoolize with `--ltdl' argument.
2193 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2194 * NEWS: Update.
2195 Suggested by Eric Blake.
2197 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2199 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2200 reported by Ralf Wildenhues.

2217 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2218 to...
2219 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2220 AT_CHECK_M4.
2221 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2222 `expout' as the last parameter.
2223 * tests/tools.at: Adapt to the above change.
2225 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2227 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2228 information about race-free implementations of mkdir.
2230 2006-06-04 Eric Blake <ebb9@byu.net>
2232 * bin/autoreconf.in (help): Document M4 environment variable.
2233 * bin/autoconf.as (Usage): Likewise.
2234 * bin/autom4te.in (help): Likewise.
2235 * doc/autoconf.texi (autom4te Invocation): Likewise.
2237 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2239 * NEWS: GNU make now recommended for VPATH builds.
2240 Mention that some macros are now documented to be obsolescent.
2241 * doc/autoconf.texi:
2242 Prefer "current" to "modern" to describe
2243 currently-used (albeit perhaps old-fashioned) hosts.
2244 Mention which ancient features no longer need to be worried about.
2245 setgid -> set-group-ID
2246 setuid -> set-user-ID (these are the Posix terms)
2247 Fix some misuses of "only".
2248 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2249 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2250 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2251 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2252 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2253 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
2254 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
2255 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2256 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2257 Mention that these macros are obsolescent.
2258 (Installation Directory Variables): shall -> should
2259 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2260 Mention that it's now safe to use 3 and 4.
2261 (Limitations of Usual Tools): cp -r is now specified by Posix.
2262 Omit longwinded and obsolescent discussion of cp -f.
2263 Modernize discussion of expr, ls.
2264 (Limitations of Make): Modernize discussion of VPATH builds.
2265 Mention $? as a workaround in some cases.
2266 * doc/install.texi (Basic Installation):
2267 Mention "./configure; make; make install" first. Be more
2268 specific about why this file is generic. Remove unnecessary
2269 parens. Remove misleading "only". Remove obsolete advice
2270 about csh. Don't say "configure" takes awhile; say it
2271 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2272 and CC=c99 rather than CC=c89, as these are blessed by current
2273 Posix. Recommend GNU make if doing a VPATH build.
2275 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2277 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2278 examples involving shell prompts.
2280 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2281 and Paul Eggert <eggert@cs.ucla.edu>
2283 * doc/autoconf.texi (Here-Documents): Add details about the
2284 pre-ksh93g bug. Reword slightly to make it clearer. Consistently

2296 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2298 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2299 about quoting the case statement, just in case.

2310 comment.
2312 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2314 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2315 argument with leading hyphen. Problem reported by Paul Eggert.
2317 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2319 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2320 about quoting ac_try: quote all of it, if any of it seems suspicious.
2321 This means we don't have to worry about ${ or sed any more.
2322 Also, double-quote the case statement, to work around misuses via
2323 underquoting as reported by Ralf Wildenhues in
2324 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2325 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2326 undocumented and dangerous macro.
2327 Problem reported by Ralf Wildenhues in
2328 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2330 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2332 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2333 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2334 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2336 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2338 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2339 since evidently some packages rely on the old, broken behavior.
2340 Problem reported by Ralf Wildenhues in
2341 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2342 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2343 pre-2006-05-26 definitions, but leave in the comments that
2344 these macros are dangerous and should not be used.
2345 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2346 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2347 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2348 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2349 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2351 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2353 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2354 the use of 'tr', since this is our only use of 'tr'.
2356 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2357 and Paul Eggert <eggert@cs.ucla.edu>
2359 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2360 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2362 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2364 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2365 the output file in the `${datarootdir}' test.
2367 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2368 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2370 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2371 mention of `datarootdir' in the input file(s), but literal
2372 `${datarootdir}' in the output file, and we haven't warned yet,
2373 then warn as well: the user may have (erroneously) used
2374 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2375 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2376 * tests/torture.at (datarootdir workaround): Extend this test.
2377 * NEWS: Update.
2379 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2380 and Paul Eggert <eggert@cs.ucla.edu>
2382 * doc/autoconf.texi (autoheader Invocation): The first argument to
2383 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2384 alternatives and clear up the language a bit.
2386 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2388 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2389 ac_config_guess, ac_config_sub, ac_configure.
2390 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2391 Fix typo that prevented an unnecessary space from being removed.
2392 Problems reported by Ralf Wildenhues in:
2393 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2395 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2397 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2398 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2399 Don't use the term "thread-safe" to talk about mkdir race
2400 conditions, since the problem is more a process than a thread
2401 issue. Problem reported by Stepan Kasal in:
2402 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2403 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2404 the test for 'install' more closely. Look at MKDIR_P first.
2405 Look in the PATH, and at /opt/sfw/bin.
2406 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2407 Don't bother to try mkdir -p, since we already check mkdir --version;
2408 just look at the version number. (There's no easy way to check
2409 for race-free implementations.)
2410 * tests/tools.at (autoconf: subdirectories): Adjust to above
2411 changes, since MKDIR_P now might end in "/mkdir -p".
2413 * doc/autoconf.texi (autoheader Invocation): Mention that the
2414 first arg of AC_DEFINE_UNQUOTED must be a literal.
2415 Problem reported by Ben Pfaff in
2416 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2418 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2419 * doc/autoconf.texi (Special Chars in Variables): New section.
2420 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2421 (Installation Directory Variables): Quote $(datadir) better.
2422 (Limitations of Builtins): Describe some of eval's trickiness.
2424 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2425 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2426 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2427 in front of every arg, not just trailing args. Quote apostrophes.
2428 (_AC_EVAL_ECHO): New macro.
2429 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2430 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2431 removed.
2432 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2433 exposed by quoting of eval argument. Put the command on line line
2434 so it logs better.
2435 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2436 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2437 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2438 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2439 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2440 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2441 Use eval more safely.
2442 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2443 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2444 to be replaced.
2445 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2446 lines, exposed by quoting of eval argument.
2448 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2449 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2451 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2452 initialization of `ac_cv_exeext', do not override it if it was
2453 already set, unless it was set to `no', for compatibility with
2454 Autoconf-2.13, and comment this.
2455 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2456 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2457 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2458 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2459 Document that this test may be overridden by setting
2460 `ac_cv_exeext'.
2462 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2464 Revert these two patches:
2466 2006-04-06 Eric Blake <ebb9@byu.net>
2467 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2468 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2469 2006-04-01.
2471 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2472 Clean up _AC_COMPILER_EXEEXT* macros.
2473 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2474 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2475 ac_file to the name of the default output file and call
2476 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2477 initial `rm' of the candidate files...
2478 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2479 the same list in subsequent `rm' calls, and for the temporary
2480 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2481 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2482 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2483 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2484 no longer needed) by libtool. Make it a cache check.
2485 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2486 copied here by mistake.
2487 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2488 _AC_COMPILER_EXEEXT.
2489 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2490 _AC_COMPILER_OBJEXT directly.
2491 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2493 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2495 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2496 Fix description of how the buggy `sed' works.
2498 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2500 Sync from Automake:
2502 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2503 ENOLCK. Only mention `make -j' when applicable. Only raise
2504 fatal errors when `make -j' is involved. Improve error message.
2506 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2508 * doc/autoconf.texi (Here-Documents): We now know more about
2509 the variable expansion in here documents bug.
2510 Thanks to Tim Rice and Stepan Kasal.
2512 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2513 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2515 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2517 * tests/autotest.at (Multiline command from M4 expansion):
2518 No failure to be expected if the shell quotes newlines in
2519 commands in the `set -x' output. Report by Tim Rice.
2520 * THANKS: Update.
2522 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2524 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2525 expansion in the here-documents used by config.status, as that
2526 runs afoul of the Korn shell version M-12/28/93d bug described in
2527 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2528 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2529 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2531 2006-05-23 Jim Meyering <jim@meyering.net>
2533 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2534 Fix typo introduced with 2006-04-02 change. It reversed the sense
2535 of the test.
2537 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2539 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2540 ac_dB slightly, to save bytes in the script.
2541 Max out at 50 lines, rather than 96; this is more likely
2542 (though not guaranteed) to avoid obscure 'sed' failures.
2544 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2546 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2547 `tr -d -' as bad option argument. Work around this by deleting
2548 an unrelated character.
2549 Report by Tim Rice <tim@multitalents.net>.
2551 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2552 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2553 Stepan Kasal <kasal@ucw.cz>
2555 * doc/autoconf.texi (Particular Programs): Do not promise that
2556 we always prefer the GNU version of the program, and that we
2557 search according to PATH; both rules can have exceptions.
2558 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2559 AC_PROG_SED. Move descriptions of limitations
2560 to the Limitations of Usual Tools section.
2561 (Limitations of Usual Tools) <sed>: Mention script length
2562 limitations with Solaris /usr/ucb/sed.
2563 <grep>: Fix wording for empty alternative. Mention that -c and
2564 -l should not be combined, and that -E and -F should not be
2565 combined.
2567 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2568 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2570 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2571 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2573 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2575 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2576 AC_DEFINE is now passed to m4_pattern_allow.
2577 * NEWS: Mention that; likewise for AC_SUBST.
2578 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2579 the parameter to m4_pattern_allow.
2580 * tests/tools.at: Add a check for that.
2582 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2584 * lib/autoconf/status.m4: Fix typos.
2586 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2588 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2589 only the files that this macro generates.
2591 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2593 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2594 the HP-UX sed limitation of 99 commands, labels do not count.
2595 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2596 in the comment.
2597 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2599 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2601 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2602 Import the following fix from coreutils:
2604 2006-01-13 Jim Meyering <jim@meyering.net>
2606 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2607 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2608 not double-quote uses of that variable, to accommodate the rare
2609 case in which getmntent is available in none of the libraries
2610 checked. This happens at least on FreeBSD 5.0.
2612 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2614 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2615 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2616 some other programs unwisely rely on these undocumented vars.
2617 But put in warning comments about them.
2618 Problem reported by Ralf Wildenhues in
2619 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2620 * NEWS: Document that these variables are intended to go away.
2622 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2624 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2625 and set the language to C++ (analogous to the equivalent Fortran
2626 tests).
2628 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2629 * doc/autoconf.texi (C++ Compiler): Document it.
2630 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2631 * NEWS: Update.
2633 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2635 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2636 that caused config.status to generate 100-command sed scripts; the
2637 portable limit is 99.
2639 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2641 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2642 variable `ac_d' instead of `d' to avoid infringing namespace.
2643 Report by Ralf Menzel.
2645 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2647 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2648 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2649 * tests/tools.at (autoconf: subdirectories): New test, taken from
2650 the corresponding problem report by Ralf Wildenhues in:
2651 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2653 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2654 Quote some uses of shell variables if they might suffer unexpected
2655 globbing. This doesn't fix all instances of quoting problems that
2656 I found, just the easy ones that look safe.
2657 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2658 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2659 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2660 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2661 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2662 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2663 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2664 Likewise.
2665 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2666 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2668 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2670 * bin/autoreconf.in ($help): Reword according to the manual.
2671 Suggested by Olly Betts.
2673 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2674 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2676 * bin/autoreconf.in: Pass the directory argument to
2677 `require_configure_ac'. Fix comment.
2678 * tests/torture.at (Configuring subdirectories): Expose this.
2679 Reported by Olly Betts.
2681 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2683 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2684 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2685 Automake as follows:
2687 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2688 `$configure_in' instead of `configure.in', to preserve
2689 directory component.
2691 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2693 * config/config.guess, config/config.sub, config/texinfo.tex,
2694 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2696 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2698 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2699 test for C99 conformance; (bool) 0.5 is an integer constant
2700 expression, but (bool) -0.5 is not. Problem reported by Fedor
2701 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2703 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2705 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2706 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2707 Warn about obsolete install-sh files. Remove stray sentence
2708 fragment and fix cross reference.
2709 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2710 install -d; this undoes the 2006-05-10 change.
2711 (MKDIR_P): Mark with AN_MAKEVAR.
2712 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2713 that we don't require $INSTALL to be thread-safe. Move comments
2714 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2715 of AC_PROG_INSTALL. Output a message saying that we're checking
2716 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2717 MKDIR_P instead of AC_SUBST.
2718 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2719 Special magic for MKDIR_P, too.
2720 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2721 a dnl.
2722 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2724 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2726 Sync from Automake, as follows:
2728 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2729 * config/install-sh: Initialize IFS, so field splitting isn't
2730 turned off later.
2731 * config/mkinstalldirs: Likewise.
2732 * config/missing: Remove superfluous quotes. Replace all uses of
2733 `[' by `test', for consistency, and for..
2734 * config/missing (sed_minuso, sed_output): New variables.
2735 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2736 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2737 Fixes `missing' to detect `--output' for help2man. Fixes
2738 PR automake/483. Report by Dennis J. Linse.
2739 (autom4te): Document in `missing --help'.
2741 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2743 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2744 * config/install-sh: Don't use 'path' to talk about file names,
2745 as per GNU coding standards. Close a race condition reported by Ralf
2746 Wildenhues and Stepan Kasal. There is still a race condition
2747 on hosts that predate Posix 1003.1-1992, but we can't help this.
2748 Don't mishandle weird characters like space on pre-Posix hosts.
2749 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2750 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2751 AC_PROG_MKDIR_P from AS_MKDIR_P.
2752 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2753 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2754 earlier editions are not (including Automake 1.8.3).
2755 Do not suggest mkinstalldirs for thread-safety.
2756 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2757 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2758 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2759 presence of special characters and race conditions.
2760 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2761 in Autoconf's name space.
2763 2006-05-10 Bruno Haible <bruno@clisp.org>
2764 and Paul Eggert <eggert@cs.ucla.edu>
2766 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2767 from Automake with minor changes.
2768 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2770 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2772 * config/install-sh: Update to Automake CVS version, as follows:
2773 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2774 * lib/install-sh: Simplify the expr implementation of dirname.
2775 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2776 * lib/install-sh: Handle --, and diagnose unknown options.
2778 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2780 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2781 `./autom4te' to create `./testsuite', since the `all' target
2782 will ensure its presence, but `installcheck' should not create
2783 the uninstalled wrappers.
2785 * tests/torture.at (Unusual Automake input files): Skip if we
2786 detect automake < 1.8.
2788 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2790 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2791 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2792 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2793 * NEWS: Update.
2795 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2797 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2798 munge (multiple) white space and other oddities.
2799 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2800 single quotes in variable assignment.
2801 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2802 and similar failures by adding multiple spaces, tabs, and other
2803 special characters.
2804 Report and different test suggested by Francesco Romani
2805 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2807 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2808 single quotes, we only need to search for single quotes; this
2809 both simplifies the search pattern, and makes us less
2810 susceptible to `echo' variations for arguments not containing
2811 single quotes.
2812 (_AC_ARG_VAR_VALIDATE): Likewise.
2814 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2816 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2817 `$*' and IFS concatenation issue with traditional shells and
2818 bash-2.04. Report by Seanster@Seanster.com.
2820 2006-05-03 Bruno Haible <bruno@clisp.org>
2822 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2823 precisely which Mac OS X versions have the od problem.
2825 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2827 * doc/autoconf.texi: Use @option systematically.
2829 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2830 and Bruno Haible <bruno@clisp.org>
2832 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2833 about 'od'.
2834 (Integer Overflow): Mention the special case of integer division
2835 overflow.
2837 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2839 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2840 traditional shells like the Solaris one that do not use the
2841 first IFS character for assembling `$*'.
2842 Prompted by a related report from autoconf_bug@nro.ca.
2844 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2845 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2847 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2848 Mention more problems with the -e option.
2850 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2852 * NEWS: Typo.
2853 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2855 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2856 in URLs to improve DVI formatted output (requires texinfo 4.6).
2857 (System Services, Systemology, Shellology): Likewise.
2858 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2859 output.
2861 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2862 continuous text.
2863 (Runtime): Fix macro argument names to match description:
2864 `action-if-found' -> `action-if-true' and similarly.
2865 (Obsolete Macros): Likewise.
2866 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2867 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2868 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2870 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2872 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2874 * ChangeLog: Typo.
2875 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2876 DVI output.
2878 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2880 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2881 /bin/sh set unsorted output.
2882 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2883 * tests/local.at: Likewise.
2885 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2887 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2888 (Integer Overflow, Null Pointers, Buffer Overruns):
2889 (Floating Point Portability, Exiting Portably): New sections.
2890 (Writing Test Programs): Fix some langauge. Recommend exiting
2891 with status 1, not merely nonzero. Clarify exit declaration.
2892 (Run Time): Move C exit status stuff to new Exiting Portably section.
2893 (Systemology): Mention Posix and levenez. Update v7 reference.
2894 (Portable Shell): Mention the Posix shell.
2896 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2898 * bin/autoconf.as (me): Replace by as_me.
2900 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2902 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2903 since as_me isn't set yet.
2905 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2907 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2908 a few minor bugs in this area.
2910 * doc/autoconf.texi (Programming in M4sh): Comment out the
2911 documentation of AS_BASENAME, for now.
2912 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2913 (Limitations of Builtins) <basename>: Do not refer to
2914 AS_BASENAME.
2915 * bin/autoconf.as (me): Don't use AS_BASENAME.
2916 (dir): Remove the unused variable.
2917 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2918 AS_DETECT_REQUIRED. All uses changed.
2919 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2920 All uses changed.
2921 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2922 (AS_BASENAME): Use "basename --" to protect against leading "-".
2923 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2924 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2925 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2926 (_AS_DIRNAME_PREPARE): Likewise.
2927 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2928 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2929 (AS_DIRNAME): Use "dirname --".
2931 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2933 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2934 of "run time" and "run-time" changed to "runtime", for consistency.
2935 * lib/autoconf/fortran.m4: Likewise (in comment).
2936 * lib/autoconf/functions.m4: Likewise.
2937 * lib/autoconf/general.m4: Likewise.
2938 * lib/autoconf/headers.m4: Likewise.
2940 * doc/autoconf.texi (Run Time): Document the exit status situation
2941 with more accuracy and detail.
2943 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2945 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2946 Archive is not officially `GNU' any more. Update URL.
2947 (Defining Directories): Likewise
2948 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2950 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2952 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2953 newline from the `trap' code to finish `config.log'; the NetBSD
2954 /bin/sh resets the exit status after an empty command, as
2955 documented in doc/autoconf.texi.
2956 Reported by Dalibor Topic <robilad@kaffe.org>.
2958 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2960 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2961 Suggested by Bruno Haible.
2963 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2965 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2966 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2967 Instead, just list the shells that we know work.
2968 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2969 changed. Be more cautious about the _cv_ variable.
2970 * tests/tools.at (Syntax of the shell scripts): Check the
2971 _cv_ variable once, at first, to avoid an internal autoconf error
2972 when sh -n does not work.
2974 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2976 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2978 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2980 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2981 use ">&-" since we're only 99.999% sure that this is portable,
2982 and since the MinGW bug is fixed in a different way.
2983 * lib/autotest/general.m4 (AT_INIT): Likewise.
2985 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2987 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2988 before opening config.log, to avoid hitting a bug on MinGW.
2990 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2992 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2993 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2994 This works around a MinGW bug reported by Eric Paire.
2995 Make sure that all writes to the log file append to it,
2996 rather than possibly losing data.
2997 * lib/autotest/general.m4 (AT_INIT): Likewise.
2999 2006-04-14 Stepan Kasal <kasal@ucw.cz>
3001 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
3002 description.
3004 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3006 * NEWS: Update.
3008 * configure.ac (AC_INIT): Bump to 2.59d.
3010 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3012 Version 2.59c.
3014 * Makefile.maint (news-date-check): Do not require a leading `*'
3015 before the release date in NEWS.
3017 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3018 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3020 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3021 the instantiated file do not contain the string 'datarootdir'
3022 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3023 @mandir@, replace the reference '${datarootdir}' by the value.
3024 * tests/torture.at (datarootdir workaround): New test.
3025 * NEWS: Advertise this temporary fixup.
3026 Based on a patch by Bruno Haible, reported and analyzed by
3027 Paul Eggert and Noah Misch.
3029 2006-04-12 Eric Blake <ebb9@byu.net>
3031 * tests/autotest.at (Debugging a failed test): Fix comment.
3033 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3035 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3036 all the changes since 2006-04-07.
3038 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3040 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3041 succeeded, but `ln -s file dir' failed, take care to remove the
3042 leftover target before the next test, to prevent its spurious
3043 failure; also make sure `ln file dir' works before selecting it.
3044 Thanks to Keith Marshall for pointing this out.
3045 * THANKS: Update.
3047 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3048 assignments in `at_debug_args', so that we put them correctly
3049 in the `run' script.
3050 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3051 Reported by Eric Blake.
3053 2006-04-11 Eric Blake <ebb9@byu.net>
3055 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3056 top-level tests after micro-suite has been run. Used in...
3057 (Debugging a successful test, Debugging script and environment),
3058 (Debugging a failed test): ...these new tests. The first of these
3059 is fixed by...
3060 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3061 macro, split out from...
3062 (AT_INIT): ...here, so that using -d also generates a run script.
3063 Document that -d inhibits top-level logging.
3064 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3065 inhibits top-level logging; debug scripts are created.
3067 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3068 check.
3069 * tests/autotest.at (Empty test, Empty check): New test to check it.
3071 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3072 from gcc.
3074 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3076 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3077 the files if a problem appears. Make the empty *.at files
3078 read-only, too. Proposed by Ralf Wildenhues.
3080 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3082 * config/Makefile.am: Add comment to force updated Makefile.in.
3084 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3085 space only patch to this file, this patch causes the Makefile.in
3086 files that include freeze.mk to be updated, and thus have a
3087 newer time stamp again, which in turn makes a pristine CVS
3088 checkout have correct time stamps.
3090 * Makefile.maint (cvs-sv): New macro, to be used..
3091 (config.guess-url_prefix, config.sub-url_prefix)
3092 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3093 point to CVS text checkout of Gnulib files.
3094 (copyright-check): Bump current year.
3095 (announcement): Do not hard-wire `./announce-gen'.
3096 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3097 correctly.
3098 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3099 `chmod +x'.
3100 (wget_files): Update config.guess, config.sub, texinfo.tex by
3101 `wget-update', now that their URLs work again.
3103 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3105 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3106 Problem noted by Paul D. Smith.
3108 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3110 * doc/autoconf.texi: Remove unused words from word list.
3111 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3112 .x-sc_trailing_space: New files.
3114 * doc/standards.texi: Sync from gnulib.
3116 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3117 `LIBOBJDIR' as experimental.
3119 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3120 with a target directory; it's internally implemented as `cp'
3121 anyway, but since Autoconf advertises the possibility to use
3122 a target directory when LN_S is `ln -s', we need to find out.
3123 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3124 analyzed by Keith Marshall <keith.marshall@total.com>.
3126 * THANKS: Update.
3128 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3130 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3131 confdefs.h as-is. In general, if it has backslash-newline or the
3132 like, then it doesn't work either to sort or to remove empty
3133 lines.
3135 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3137 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3139 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3141 * lib/autom4te.in (Automake-preselections): Preselect
3142 _AM_SUBST_NOTMAKE.
3144 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3146 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3147 apostrophe within a single-quoted string, as this is the usual
3148 tradition and is easier to read than '"'"'. Don't rely on the
3149 shell treating "$/" like '$/'. Use a more-consistent indenting
3150 style for the trap.
3152 2006-04-09 Eric Blake <ebb9@byu.net>
3154 * tests/autotest.at (Backquote command substitution),
3155 (Multiline backquote command substitution): Remove mistaken
3156 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3157 applied...
3158 (Parenthetical command substitution, Multiline parenthetical
3159 command substitution): here.
3161 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3163 Import macros from gnulib (often changing their name).
3165 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
3166 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
3167 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
3168 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
3169 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
3170 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3171 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
3172 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
3173 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
3174 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
3175 The manual mentions Gnulib more prominently.
3176 * doc/autoconf.texi (Gnulib): New node.
3177 (Pointers): Add Gnulib URL.
3178 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
3179 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3180 Gnulib section.
3181 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
3182 suggest a #define rather than a typedef for _Bool, and mention
3183 Gnulib rather than trying to substitute stdbool code.
3184 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
3185 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
3186 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
3187 AC_STRUCT_DIRENT_D_TYPE.

3239 _AS_DETECT_BETTER_SHELL:
3241 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3242 skip nonexistent directories.
3243 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3244 only shell candidates which exist.
3245 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3246 * lib/autotest/general.m4 (AT_INIT): No need to give three
3247 parameters to _AS_PATH_WALK.
3249 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3250 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3252 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3253 distinguish m4sugar macros.
3254 * tests/tools.at (autoupdating with aclocal and m4_include):
3255 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3256 test case by Noah Misch <noah@cs.caltech.edu>.
3258 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3260 Revert my change from 2006-03-17, in other words:
3261 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3262 and DUALCASE=1.
3263 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3264 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3265 it is set.
3267 2006-04-07 Eric Blake <ebb9@byu.net>
3269 * doc/autoconf.texi (Programming in M4sh): Document that
3270 AS_MKDIR_P exits the script on failure.
3271 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3273 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3275 * config/elisp-comp, config/install-sh, config/mdate-sh,
3276 config/missing, config/mkinstalldirs: Sync from Automake.
3278 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3279 from Automake.
3281 * doc/make-stds.texi: Sync from gnulib.

3292 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3294 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3295 whether `set' quotes correctly: redirect stderr of the tested
3296 `set', and use a subshell, for Ultrix; use `sed' instead of
3297 `grep' for zsh `set' which may write binary output; match only
3298 at the beginning of a line, to avoid false positives.
3299 In order to avoid false positives by unrelated variables with
3300 multiline content, put the dump algorithm in a subshell and
3301 unset all variables containing newlines (except some which are
3302 special to the shell). Warn about cache variables that are
3303 unset.
3305 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3307 * config/config.guess, config/config.sub, config/texinfo.tex:

3316 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3317 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3318 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3319 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3321 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3322 shell issue with double-quoted command substitutions of native
3323 commands.

3344 * tests/Makefile.am (maintainer-check-posix):
3345 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
3347 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
3348 ac_config_<foo>s again, sometimes normalized, sometimes not.
3349 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3350 (AC_CONFIG_COMMANDS): Do not do so here.
3351 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3352 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3353 2005-07-25 rewrite. Noticed by Noah Misch.
3355 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3356 _AC_PRESERVE_HELP_ORDER, ...
3357 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3359 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3360 inside m4_expand_once; it is redundant.
3362 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3363 for --help from Cygnus `configure.'
3365 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

3378 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3379 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3380 * doc/autoconf.texi (Help Formatting): New node.
3381 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3383 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3385 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3386 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3387 lib/autoconf/types.m4, lib/autotest/general.m4,
3388 tests/mktests.sh, tests/torture.at: White space cleanup:

3398 empty test suite works.
3399 * tests/autotest.at (Empty test suite): Remove xfail.
3401 2006-04-05 Noah Misch <noah@cs.caltech.edu>

3404 TAGS to ac_config_<foo>s.
3405 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
3406 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
3407 normalizing it, consistent it with previous releases.
3408 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3410 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3412 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3413 Use simplified args that Eric Blake originally suggested.
3415 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3417 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3418 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3419 Use 'comm' rather than N instances of grep; this also fixes a bug
3420 whereby substrings were incorrectly matched, causing us to not
3421 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3422 (exclude_list): Exclude empty macros.
3423 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
3425 Use awk rather than grep -E or egrep, to avoid

3428 Switch from grep to awk syntax.
3429 (ac_exclude_script): Renamed from ac_exclude_egrep.
3430 (au_exclude_script): Renamed from au_exclude_egrep.
3432 2006-04-04 Noah Misch <noah@cs.caltech.edu>
3434 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
3435 a subdirectory subject to Cygnus `configure'.
3436 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3438 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3439 report request when we have no AC_PACKAGE_BUGREPORT.
3441 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3443 * THANKS: Update.

3446 generated files.
3448 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
3449 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
3450 typedef'ed restricted pointer, to catch a compiler bug on
3451 HP-UX 11.x, and fix warnings so it passes with -Werror.
3452 (_AC_PROG_CC_C99): Likewise.
3453 Reported by Albert Chin <china@thewrittenword.com>.

3473 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
3474 to log, point to testsuite output tree.
3476 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

3506 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3507 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3508 ac_file to the name of the default output file and call
3509 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3510 initial `rm' of the candidate files...
3511 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3512 the same list in subsequent `rm' calls, and for the temporary
3513 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3514 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3515 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3516 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3517 no longer needed) by libtool. Make it a cache check.
3518 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3519 copied here by mistake.
3520 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3521 _AC_COMPILER_EXEEXT.
3522 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

3555 Autoconf version number despite a zero- or one-argument AC_INIT.
3557 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
3558 subordinate tools.
3559 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
3560 * doc/autoconf.texi (autoreconf Invocation): Document it.
3562 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

3574 the correct lines of the input file by subtracting..
3575 (_au__first_line): ..this new definition.
3577 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
3578 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
3579 Remove stray newline in output.
3580 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
3581 AC_DEFUN this for autoconf, including the obsoletion diagnose.
3582 Fixes autoupdating of code where the replacement output contains
3583 m4sugar macros.
3584 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
3585 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

3587 * tests/tools.at: Several new tests for all of this.
3588 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
3589 hairy details.
3590 The AC_LANG_SAVE issue was reported against Libtool by
3591 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
3592 Kristian Kvilekval <kris@cs.ucsb.edu>.
3594 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3596 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3597 switch all of them on and of when necessary. Fixes the bug when
3598 m4sugar macros (e.g., m4_define) were expanded after the first
3599 automatic update (e.g., after AC_PREREQ or AC_INIT).

4146 rather than "sed" when talking about Sed in general.
4147 (Particular Programs): Likewise.
4148 (Coding Style): y is like s with respect to / and ,.
4149 (Limitations of Usual Tools): Document the weird restrictions
4150 that Posix has about { }. Use better quoting.

4173 2005-12-31 Stepan Kasal <kasal@ucw.cz>
4175 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;

4238 Factor functionality to..
4239 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
4240 `AC_SUBST($1)' in the public version.
4241 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
4242 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

4290 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
4292 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
4293 AC_LANG_PROGRAM, fixing a typo. Don't give details about
4294 the inner workings of AC_LANG_FUNC_LINK_TRY.
4295 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
4296 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4297 by the function rather than ignoring it.
4298 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4299 comparing its address. Intel's interprocedural optimization was
4300 outsmarting the old heuristic. Problem reported by
4301 Mikulas Patocka.
4303 2005-10-19 Stepan Kasal <kasal@ucw.cz>
4305 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

4312 2005-10-04 Stepan Kasal <kasal@ucw.cz>
4314 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
4315 before removing it (chmod -R u+rwx); there are three instances of this.
4317 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4318 Stepan Kasal <kasal@ucw.cz>
4320 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4321 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4322 make its content writable before removing it. Remove an errorneous
4323 comment from the end, where the logs of the failed tests are copied
4324 to the main log file.
4326 2005-09-27 Stepan Kasal <kasal@ucw.cz>
4328 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
4329 in case the computer is too quick. Double quote the configure.ac
4330 snippets.
4332 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
4333 problems if the testsuite were running too fast.
4335 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4337 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4338 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4339 (which belong to Xt, not X itself). See Debian bug 327655.
4340 * NEWS: Mention this.
4342 2005-09-07 Stepan Kasal <kasal@ucw.cz>
4344 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
4346 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
4348 * config/move-if-change: Don't output "$2 is unchanged";
4349 suggested by Ben Elliston. Handle weird characters correctly.
4351 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4353 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4354 calls, so that the final expansion of this macro is shorter.
4355 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4356 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4357 the cleanup there. Use AS_VAR_* macros, to be more general.
4358 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4360 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4362 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
4364 2005-09-01 Stepan Kasal <kasal@ucw.cz>
4366 * doc/autoconf.texi (Configuration Headers): Add an index entry
4367 for AH_HEADER.
4369 2005-08-26 Pavel Roskin <proski@gnu.org>
4371 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
4372 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
4373 running xmkmf.
4375 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4377 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4378 The previous patch didn't work, so try a better one.
4380 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4382 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4383 in the example. Reported by Bruno Haible.
4384 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4385 "if $undefined_var;" succeeds with my shell.
4387 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4388 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4389 but change the m4_divert_text to m4_divert_once.
4391 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4393 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4394 Work around bug in Solaris /usr/xpg4/bin/awk.
4395 The bug is present in at least Solaris 8 through 10.
4397 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4399 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4400 some evil values and relying on the fact that $* concatenates the
4401 parameters by the first character from IFS.
4403 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4404 Stepan Kasal <kasal@ucw.cz>
4406 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4407 first header appears, define AH_HEADER.
4408 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4409 Update limitations about when to call AC_CONFIG_HEADERS.
4410 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4411 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4412 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4413 ``Configuration Actions''; fix their index entries.
4415 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4416 options correctly. Process N-M as M-N if M is smaller than N.
4417 Process ranges correctly so that N-N will run only N.
4418 Sort and uniquify the tests that will be run. If there is more
4419 than one test, reinsert the banners for the tests.
4420 * tests/autotest.at (Keywords): Unmark XFAIL.
4422 2005-08-23 Stepan Kasal <kasal@ucw.cz>
4424 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4425 before passing the macro name to AH_TEMPLATE.
4427 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4428 now opens log after option processing; in particular, --version
4429 and --help do not touch config.log.
4431 * Makefile.maint: Revert the change from 2005-08-12.
4433 2005-08-22 Stepan Kasal <kasal@ucw.cz>
4435 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
4436 common code to...
4437 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
4439 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4441 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4442 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4443 Language cleanup.
4445 * doc/autoconf.texi (Defining Symbols, Changed Results):
4446 Prepend to LIBS, not append, in examples.
4448 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4450 When building in place, set srcdir="."; suggested by Tim Van Holder.
4452 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4453 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4454 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4455 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4456 does not mean "no --srcdir option".
4458 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4460 * tests/autoscan.at (autoscan): New file.
4461 * tests/suite.at: Use it.
4462 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4463 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
4465 * tests/autotest.at (Keywords): Test keywords combinations.
4467 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4469 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4470 add "2>&1"; gzip 1.2.4 prints help on stderr.
4472 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4474 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4475 was pushdef'ed twice while popped only once. Push it only once.
4476 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4478 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4480 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

4485 * Makefile.maint: Update from Bison.
4487 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4488 "<tab>" in comment, so that the point is understandable.
4490 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4492 Rewrite substantial part of lib/autoconf/status.m4.
4493 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4494 and CONFIG_COMMANDS are not processed in four separate loops.
4495 Instead, there is one main loop. This alows that the common code
4496 is expanded only once, thus config.status (and configure) is smaller.
4498 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4499 the AC_LIST_FILES and cousins macros are no longer used.
4501 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4502 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4503 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4504 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4505 contain the initialization, nor the for loop, nor the associated
4506 commands; all these go to ...
4507 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4508 _AC_OUTPUT_CONFIG_STATUS.
4509 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4510 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4511 (_AC_OUTPUT_FILE): The creation of the sed script ...
4512 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4513 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4514 _AC_OUTPUT_MAIN_LOOP.
4515 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4516 _AC_CONFIG_COMMANDS): Use ...
4517 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4518 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4519 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4520 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4521 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4522 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4523 ... new macros.
4524 (_AC_CONFIG_UNIQUE): Update.
4525 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4526 Replaced by this ...
4527 (_AC_LIST_TAGS): ... new common macro.
4528 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4529 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4530 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4531 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4532 this didn't belong to the `config commands' section.
4533 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4534 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4535 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4536 to the `config commands' section either.
4537 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4538 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4540 ... and many changes to the comments nearby.
4542 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4543 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4544 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4545 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4546 (#define header templates): The comment at the top of the generated
4547 header now includes the name(s) of the source file(s).
4549 Several unrelated small changes:
4551 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4552 parameter to AC_DIAGNOSE.
4553 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4554 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4555 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4556 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4557 with AU::AC_OUTPUT.
4558 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4559 in AC_OUTPUT doesn't double-quote it either.
4560 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4561 parameters.

4584 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4585 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4586 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4587 (AC_ARG_VAR): ... here.

4599 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4600 to INIT_PREPARE.
4601 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4602 its value to shell variable ac_precious_vars and call
4603 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4604 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4605 _AC_ARG_VAR_VALIDATE.

4630 Fix my changes from 2005-07-01; reported by Noah Misch.
4631 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4632 description, the macro now accepts only a single tag.

4641 versions of autoconf.
4643 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4645 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

4648 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4650 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4651 sed substitution command, so that we allow | in program prefixes
4652 and program suffixes. (& is a problem anyway; we're not fixing
4653 that here.)
4654 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4655 configure_input, top_builddir, srcdir, etc.
4656 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4657 PATH_SEPARATOR in AUTOTEST_PATH.
4659 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4661 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the

4667 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4668 directories with weird names. Apparently some people like living

4692 Likewise for --header; moreover, recognize --he and --h as shortcuts
4693 for --help in that case.
4695 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4696 matches the order of execution. No code changed.

4718 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4719 (AC_SUBST): Call it.
4720 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4721 the directory specific variables; but don't call it for configure_input.
4723 2005-06-28 Derek Price <derek@ximbiot.com>
4725 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4726 addition.
4728 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4730 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4731 directory have inherent problems with special characters like spaces,
4732 due to limitations in Make syntax. Problem reported by Alexandre
4733 Duret-Lutz.
4734 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4749 variable into diagnostic. Make the diagnostic an error, not a warning,
4750 because we really don't support spaces and suchlike in dir names.
4751 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4752 Don't worry about backslashes in srcdir; it can't happen now.

4769 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4771 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4779 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4780 b, t, r, w commands require single space, while : cannot have any.
4781 (Special Shell Variables): Fix sed code this in the example.
4782 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4783 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4785 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4786 expand to the empty list. Don't use two pairs of m4_changequote,
4787 it's not necessary.
4789 2005-06-20 Derek Price <derek@ximbiot.com>
4791 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

4795 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4796 * doc/autoconf.texi:
4797 Don't mention Solaris versions so much, if a
4798 problem is common to all extant versions of Solaris. Say "SunOS
4799 4" instead of "SunOS" for SunOS 4.
4800 (awk): Mention more of the limitations of traditional Awk.
4801 (cat): Don't talk about cat -v.
4803 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

4808 to be compatible with glibc strverscmp.
4809 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4811 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4812 on Mac OS X 10.4 reported by Peter O'Gorman in:

4814 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4815 Use shell builtins rather than 'expr', to work around expr bug.
4817 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4819 * doc/autoconf.texi: "filesystem" -> "file system".
4820 "behaviour" -> "behavior".

4833 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4834 quotes and backslashes. Patch from Derek Price.

4839 AS_TR_SH.
4841 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4843 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4844 -u, since it outputs chatter if the input files are the same.
4845 Problem reported by Ralf Menzel.
4847 2005-06-08 Derek Price <derek@ximbiot.com>
4849 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4850 renaming them since they are about to be redefined anyhow.
4852 2005-06-08 Derek Price <derek@ximbiot.com>
4854 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4855 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4856 Move m4_undefine to alphabetical order.
4858 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4860 * README: Recommend GNU M4 1.4.3 or later.
4861 * doc/autoconf.texi (Introduction): Likewise.
4862 Reword to avoid some formatting glitches.
4863 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4864 Clarify explanation of HP compiler bug.
4865 Redo example output tp match current CVS snapshot.
4866 Use @example.org in email addresses when the examples
4867 might get inadvertently cut-and-pasted into user code.
4868 Remove example of autom4te usage that doesn't seem to work now.
4869 Use modern AC_INIT (except when the example is meant to be
4870 shown with Autoconf 2.13).
4871 Update ksh info for Solaris 9 and later.
4872 KB -> kB.
4873 Modernize description of Automake versions a bit.
4874 Don't claim a future version of Autoconf is near.

4884 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4885 Tru64 ksh pattern matching bug. Reported against Libtool by
4886 Albert Chin <libtool@mlists.thewrittenword.com> and
4887 Nicolas Joly <njoly@pasteur.fr>.
4889 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4891 m4_cdr of one-member list was [[]] (one-member list containing an
4892 empty string) instead of [] (an empty list. Callers were skewed to
4893 match this misbehaviour. As a consequence of this:
4894 - m4_foreach([x], [], [foo]) expanded to `foo', while
4895 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4896 This bug has been fixed:
4898 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4899 expand to an empty string; print error msg if called without
4900 an argument list.
4901 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4902 misbehaviour; handle [] and [[]] correctly.

4910 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4912 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4913 swallow records with more than 99 fields.
4914 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4915 parse the long line.
4917 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4919 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4920 swallow literals longer than 399. Reported by Ralf Wildenhues.
4921 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

4924 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4926 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4927 to gfortran, and make these the first two compiler names
4928 checked (following the general autoconf preference for gcc).
4930 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4932 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4933 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4934 (testsuite): Make sure autotest.m4f is up-to-date before using it.

4938 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4939 expression of unbounded size when processing the --list
4940 option. This runs afoul of a limit of 399 bytes per regular
4941 expression on AIX. Problem reported by Ralf Wildenhues.
4943 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

4950 Reword description of line replacement.
4952 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4954 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4955 now contain newlines, and substituted files must be referenced on
4956 a line alone; the sed scripts to substitute them are now very
4957 different.
4958 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4959 commands can be put in a sed script portably.
4960 * doc/autoconf.texi (Setting Output Variables): Document above

4972 * tests/local.at: Don't attempt to check for negated character
4973 classes in shell scripts. The test was too brittle.
4975 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4977 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4978 * doc/autoconf.texi (Limitations of Builtins): Document this
4979 limitation.
4981 2005-05-24 Stepan Kasal <kasal@ucw.cz>

4991 messages when ac_unique_file is not found.
4992 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4993 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo

5006 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5008 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
5009 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
5010 (ac_top_builddir): ... this ...
5011 (ac_top_build_prefix): ... to this; the old name is also kept, for
5012 backward compatibility.
5013 (ac_top_builddir_sub): New variable, without the trailing slash,
5014 always nonempty.
5015 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
5016 * doc/autoconf.texi (Configuration Actions): Rename
5017 ac_top_builddir to ac_top_build_prefix.
5018 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
5019 at_top_builddir to at_top_build_prefix.
5020 * lib/autotest/general.m4 (AT_INIT): Likewise.
5022 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5024 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
5025 of confdefs.h .
5027 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5029 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
5030 argument to m4_foreach. I guess it was necessary in the past,
5031 but I think it's a no-op now.
5033 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5035 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5036 ``cat <<_ACEOF'' commands to one.
5037 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
5038 * lib/autoconf/status.m4: On various places, use expr instead of
5039 ``echo|sed.''
5040 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
5041 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
5042 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
5043 a range.
5044 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
5045 the wrong patterns between ``case'' and ``esac.'' The previous
5046 code had false positives.
5048 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
5050 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
5051 as on 2005-05-02.
5052 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
5053 Mention LIBOBJDIR.

5093 2005-05-13 Stepan Kasal <kasal@ucw.cz>
5095 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
5096 check.
5097 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
5098 enough arguments, similarly as in m4_bpatsubsts.
5100 2005-05-12 Stepan Kasal <kasal@ucw.cz>
5102 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
5103 of absolute paths.
5105 2005-05-11 Stepan Kasal <kasal@ucw.cz>
5107 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
5108 for absolute directory names in one loop.
5109 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
5110 abbreviations of --version and --debug.
5112 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
5114 * doc/autoconf.texi (Autoconf Language): Be more precise about
5115 quoting rules. Problems noted by Stepan Kasal.
5116 Also, throughout this document, be more careful about white space.
5117 "blank", "white space", and "space" all have different meanings
5118 and we should be careful to say what we mean.
5120 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
5122 Fix C++ related problems reported by Werner Lemberg.
5123 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
5124 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
5125 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
5126 avoid problems with C++ and throw.
5127 * tests/compile.at: .cpp, not .cc.
5129 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
5131 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5133 * doc/autoconf.texi (Generic Functions): Typos.
5135 2005-05-02 Gary V. Vaughan <gary@gnu.org>
5137 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
5138 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
5139 set by latest automake.
5141 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
5143 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
5144 outputs 0 on GNU/Linux these days.
5146 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
5148 * doc/autoconf.texi (Autoconf Language): Add more description
5149 about quoting heuristics.
5150 (Limitations of Builtins): Describe "set -" problems.
5152 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5154 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
5155 not newline.
5157 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5158 by AC_DEFINE; it was a mistake.
5159 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5161 2005-04-25 Stepan Kasal <kasal@ucw.cz>
5163 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
5165 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5167 * doc/autoconf.texi (External Software): Quadrigraphs are not
5168 processed correctly in AS_HELP_STRING; avoid this in the examples.
5169 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5170 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5171 comment and reduce m4_default([foo], []) to [foo].
5172 (m4_strip): Update the explanation.
5174 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5176 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5177 Remove core.conftest.* too; it's generated by Tru64 5.1.
5178 Problem reported by Jennis Pruett.
5179 * lib/autoconf/functions.m4
5180 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5181 Don't bother to remove core files; AC_RUN_IFELSE should do that
5182 for you.
5184 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5186 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
5188 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

5193 2005-04-15 Stepan Kasal <kasal@ucw.cz>
5195 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
5196 the comment.
5198 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
5200 * doc/autoconf.texi (External Software, Package Options): Add
5201 examples showing how to implement --with-* and --enable-* options.
5203 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
5205 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
5206 as well as configure.in. Problem reported by Gregorio Guidi.
5208 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
5210 * doc/autoconf.texi (Particular Functions): Use gnulib's current
5211 pattern for alloca snippet.
5213 2005-04-04 Stepan Kasal <kasal@ucw.cz>
5215 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
5217 2005-04-01 Stepan Kasal <kasal@ucw.cz>
5219 * doc/autoconf.texi (Generic Programs): Fix a typo.
5221 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
5223 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
5224 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
5226 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5228 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5229 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5230 whole-archive (-zallextract, -zdefaultextract) options in the hope of
5231 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5232 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5234 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5236 * NEWS: The configure command now warns you if you attempt to use
5237 a directory whose name contains a special character like space,
5238 newline, or "\".
5239 * doc/autoconf.texi (Installation Directory Variables): Allow
5240 "," in file names. Do not use \@; it's not a portable regexp.
5241 * bin/Makefile.am (edit): Likewise.
5242 * lib/Makefile.am (edit): Likewise.
5243 * tests/Makefile.am (edit): Likewise.
5244 * tests/semantics.at: Likewise.
5245 * tests/torture.at: Likewise.
5246 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
5247 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
5248 * doc/autoconf.texi (File System Conventions): Warn about
5249 unportable file names.
5250 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5251 (AC_INIT): Use it.
5252 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5253 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5254 ac_pwd, and quote srcdir.
5255 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5257 * doc/autoconf.texi: Fix some systematic formatting problems.
5258 ".)" needs a following @: if not at the end of a sentence, and
5259 similarly for "!)". "etc." should be preceded by a comma.
5260 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5262 2005-03-22 Bruno Haible <bruno@clisp.org>
5264 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5265 argument is often called 'build-aux'.
5267 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5269 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5270 macro AC_TRY_LINK is obsolete.
5271 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5272 `AC_CONFIG_FILES'.
5274 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5276 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5277 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5278 from a Common Lisp's `cl'.
5279 (AC_PROG_CXX): Behave according to the documentation: don't
5280 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5281 make the variable CCC precious; use `cl.exe', not `cl'.
5283 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5284 Alexandre Duret-Lutz <adl@gnu.org>
5286 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5287 /dev/null, as "configure" shouldn't read stdin, and this insulates
5288 us from problems (e.g., when testing for "cl"). Also, do this
5289 redirection before invoking "hostname" or "uname", and keep the
5290 original input stream available via...
5291 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5292 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5293 bother with "</dev/null" since it's now done at the top of
5294 'configure'.
5295 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5296 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5297 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5298 * doc/autoconf.texi (File Descriptor Macros): New section.
5299 (Printing Messages): Mention it.
5300 * tests/base.at (Input/Output): New test.
5302 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5304 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5305 newline if neither \c nor -n work, as that would output two
5306 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5308 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5310 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5311 This causes that any required macros inside will get before the if.
5312 * doc/autoconf.texi (autom4te.cache): A typo.
5314 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5316 Undo previous change, except keep the change to
5317 lib/autoconf/programs.m4 that replaced grep with shell
5318 pattern-matching. This is because net-snmp configure reads stdin.
5319 Reported by Noah Misch.
5321 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5323 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5324 from /dev/null, as "configure" shouldn't read stdin, and this
5325 insulates us from problems (e.g., when testing for "cl").
5326 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5327 before invoking "hostname" or "uname".
5328 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5329 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5330 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5331 "</dev/null" since it's now done at the top of 'configure'.
5332 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5333 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5334 Also, replace grep with shell pattern-matching, to save a process.
5336 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5338 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5339 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5340 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5341 compiler.
5343 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5345 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5346 grep -q isn't portable. Improve grep -s explanation.
5347 Problem reported by Dan Manthey.
5349 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5351 * doc/autoconf.texi (Special Shell Variables): Clarify
5352 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5354 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5356 * doc/autoconf.texi: Use @acronym for DJGPP.
5357 Fix some @code's that should have been @env's, and vice versa.
5358 Sort environment variable names.
5359 Mention that shells no longer inherit IFS.
5360 Don't recommend PATH_SEPARATOR=';' so strongly.
5361 Mention that $RANDOM might expand to the empty string.
5362 "symlink" and "soft link" -> "symbolic link".
5363 Improve mktemp description (reported by Bruno Haible).
5365 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5367 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5368 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5369 Likewise.
5370 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5371 Likewise.
5373 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5375 * NEWS: Mention AT_COPYRIGHT.
5377 * tests/local.at (AT_CMP): Use diff directly on input files rather
5378 than copying them.
5380 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5381 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5383 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5384 and Paul Eggert <eggert@cs.ucla.edu>
5386 * tests/autotest.at (Empty test suite): New test.
5387 * tests/torture.at (Substitute and define special characters)
5388 (Substitute a 2000-byte string, Define to a 2000-byte string)
5389 (Substitute a newline, Define a newline): New tests.
5391 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5393 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5394 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5395 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5396 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5397 (Standard regular expressions): New test.
5398 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5399 excess test name quoting.
5400 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5401 CPPFLAGS to `configure' instead of setting it in `configure'.
5403 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5404 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5405 on some platforms.
5407 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5408 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
5410 * tests/local.at (AT_CMP): New macro.
5411 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
5412 (AC_SAVE_STATE): Move environment grep...
5413 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
5414 (AT_CONFIG_CMP): New macro.
5415 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
5416 * tests/c.at (Extensions): Do not exit early.
5417 * tests/atlocal.in: Inherit $GREP.
5419 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
5420 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
5422 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
5423 (AC_COPYRIGHT): Factor header comment portion out and move into...
5424 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
5425 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
5426 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
5427 --version output.
5428 * tests/local.at: Add Autoconf test suite copyright notice.
5429 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
5431 2005-02-04 Bruno Haible <bruno@clisp.org>

5442 2047-byte limit on line length of portable text files.
5443 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5444 Use newline as a separator, not space.

5502 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5503 Update the long comment explaining it.
5505 m4_require no longer writes an ``is required by'' line to the
5506 execution stack. It contains only one bit of non-redundant
5507 information: that the macro was required, not called. And even
5508 this bit is useless in most situations: have you ever met a macro
5509 which both calls and requires the same macro?
5511 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5512 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5520 * tests/m4sugar.at (m4_require): Expect output without the
5521 ``is required by'' messages.
5523 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5525 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5526 rather than x for expr.
5528 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5529 this is safe.
5530 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
5531 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

5555 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
5557 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5559 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5560 Warn about newline stripping in `` and $(). Update Solaris
5561 version to 9.
5562 (Limitations of Builtins): Use expr "X...", not expr "x...", as

5565 stripping.
5567 2005-01-19 Stepan Kasal <kasal@ucw.cz>

5589 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5591 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5613 (_m4_divert_n_stack): New macro; the expansion is
5614 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
5615 otherwise.
5616 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5617 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5618 stored in _m4_divert_diversion or _m4_divert_dump.
5619 (m4_divert_pop): When the parameter is given, compare the symbolic
5620 name with the last diversion pushed on the stack. Previously, the
5621 current diversion was compared with the numeric value of the
5622 diversion given as the parameter.
5623 (m4_require): If the macro hasn't been expanded yet, call ...
5624 (_m4_require_call): this new macro.

5657 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

5710 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
5711 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

5894 * bin/autoconf.in: Delete it; we always build it.
5896 2004-12-08 Noah Misch <noah@cs.caltech.edu>
5898 * lib/autotest/general.m4 (AT_INIT): Replace a `tr' with a `sed'. Join
5899 PATH members so as to not prepend an empty element. Move a comment.
5900 * Makefile.am (SUBDIRS): Build in `tests' last.
5901 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
5903 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
5905 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
5906 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5907 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
5908 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
5910 2004-12-07 Stepan Kasal <kasal@ucw.cz>
5912 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous
5913 patch: extra "-l"s.
5915 2004-12-06 Paul Eggert <eggert@cs.ucla.edu>
5917 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
5918 looking elsewhere for getmntent. Problem reported by Mark D. Baushke.
5919 * doc/autoconf.texi (Particular Functions): Mention new behavior.
5921 2004-12-03 Stepan Kasal <kasal@ucw.cz>
5923 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
5924 out the common code to ...
5925 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
5926 value of the #define--default to 1, iff the macro was called
5927 with exactly one parameter.
5929 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5931 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5932 "char c = '\200';" rather than "char c = 0x80;" as the
5933 latter doesn't conform to the strict C standard due to
5934 overflow on signed char hosts.
5936 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5937 to -qlanglvl=ansi. We don't want to disable extensions.
5939 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
5941 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
5942 (Using Autotest, testsuite Scripts, Writing testsuite.at):
5943 Reword slightly to avoid some English-language problems noted

5957 Automake (not without Autoconf).
5958 (Introduction): Mention lists.gnu.org.
5959 * BUGS: Don't mention bugs.gnu.org.
5960 Remove mention of ancient libtool compatibility problem.
5961 * NEWS: Mention that bugs.gnu.org is kaput.
5962 * README: Likewise. Mention where mailing list archives can be found.
5964 2004-11-28 Stepan Kasal <kasal@ucw.cz>

5984 in my editing of the previous patch. Problem reported
5985 by Alexandre Duret-Lutz.
5987 2004-11-22 Stepan Kasal <kasal@ucw.cz>
5989 * doc/autoconf.texi (Autoconf Language): Explain that
5990 ``descriptions'' may not be double quotes.
5991 (Quotation Rule Of Thumb): Likewise.
5992 (Pretty Help Strings): Likewise; remove the wrong comment;
5993 simplify the examples and improve their quoting.
5995 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5997 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5998 the $1_found variable, don't test whether the file is executable;
5999 Both things are checked ...
6000 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
6001 the former ``test -f''.
6002 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
6004 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
6006 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
6007 use cp -R instead.
6009 2004-11-10 Derek R. Price <derek@ximbiot.com>
6011 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
6012 limitations. Reorder paragraphs for clarity.
6014 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
6016 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
6017 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
6018 variants", "Unix", and some related minor wording fixups.
6020 (Shellology, Special Shell Variables): Document that the Zsh
6021 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
6022 to Alexandre Duret-Lutz for this info.

6033 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
6035 * doc/autoconf.texi (auindex): New macro.
6036 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
6037 Problem reported by Stepan Kasal.
6039 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
6041 Fix problems reported by Andreas Buening in:
6042 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
6043 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
6044 in test makefile.
6045 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
6046 readable; it's not true in OS/2-emx.
6048 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
6050 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
6051 "/usr/include", clear ac_x_includes instead of leaving it as "no"
6052 (trivial change). Problem and patch reported by Andrew Church in:
6053 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
6055 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
6057 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
6058 three args in examples. Problem reported by Frederik Fouvry in:
6059 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
6060 Also, fix some minor spacing and punctuation bugs.
6062 2004-09-02 Akim Demaille <akim@epita.fr>
6064 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
6065 "case" to restore ordering.
6066 Reported by Stepan Kasal.
6068 2004-08-26 Akim Demaille <akim@epita.fr>
6070 * doc/autoconf.texi: Minor typos and stylos.

6074 * configure.ac (AC_INIT): Bump to 2.59c.
6076 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
6078 Version 2.59b.
6080 * README: Add advice about m4 1.4.2.
6082 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
6083 texinfo.tex for now (done by hand now).
6084 * Makefile.maint (wget_files, cvs_files):
6085 Remove ansi2knr.c; nobody uses it.
6086 (ansi2knr.c-url_prefix): Remove.
6087 (cvs-update): Fix test for failure. I don't know why it ever
6088 worked...
6090 * doc/autoconf.texi: Update URLs, some of which went stale.
6091 Use @uref rather than @href.
6093 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
6094 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
6096 * config/config.guess, config/config.sub, config/elisp-comp,
6097 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
6098 doc/fdl.texi, doc/standards.texi: Sync with master copy.
6100 * NEWS, TODO, configure.ac, bin/autoscan.in,
6101 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
6102 doc/install.texi, lib/Autom4te/Configure_ac.pm,

6106 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
6107 tests/tools.at, tests/torture.at:
6108 Use "file name" rather than "filename" or "path",
6109 to be consistent with the terminology of the GNU coding standards.
6111 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
6113 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
6114 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
6115 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
6116 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
6118 More fixes to support spaces in the name of the build directory.
6119 This isn't a complete fix but it's an improvement.
6121 * bin/autoconf.as (autom4te_options): New var.
6122 Use it instead of appending to AUTOM4TE, so that we can allow
6123 spaces in the build directory's absolute name.
6124 * bin/autoheader.in ($autoconf): Allow spaces in file names.
6125 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
6126 AT_CHECK_NOESCAPE): Likewise.
6127 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
6128 main program): Likewise.
6130 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
6132 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
6133 From Ralf Corsepius in:
6134 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
6136 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
6138 * doc/autoconf.texi (Function Portability): Document isinf and
6139 and isnan. From a suggestion by Kevin Ryde.
6141 * lib/Autom4te/General.pm (END): Return correct exit status even
6142 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
6144 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
6146 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6147 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6148 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
6150 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6152 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
6153 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
6154 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
6155 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
6156 * lib/autom4te.in (Automake-preselections): Preselect
6157 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6159 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6161 * lib/autom4te.in (Automake-preselections): Preselect
6162 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6163 trace them.
6165 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6167 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6168 Tru64.
6169 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6170 Document problem with "`""`" in pdksh POSIX mode.
6172 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6174 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6175 with pdksh, too. Problem reported by Patrick Welche via
6176 Gary V. Vaughan.
6177 * doc/autoconf.texi (Shellology): Note that set -o posix is
6178 useful for pkdsh, too.
6180 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6182 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6183 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6184 Don't fail if ENV or BASH_ENV is readonly.
6185 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6186 etc. are read only. Problem reported by Ludovic Courtes.
6188 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6190 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6191 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6192 (trivial change)
6194 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6196 * doc/autoconf.texi (File System Conventions): Warn about
6197 names like "aux". Problem reported by Eric Blake.
6199 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6200 by zero instead of array size, so that we can use any arithmetic
6201 constant expression (instead of requiring an integer constant
6202 expression). This allows us to test expressions like DBL_MAX <
6203 LDBL_MAX, which didn't conform to the C standard using the old
6204 method.
6205 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6206 now that we can do floating-point tests at compile time.
6208 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6210 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6211 and LDBL_EPSILON, as the resulting expression isn't an
6212 integer constant expression and violates the C standard.
6213 Problem reported by Nelson H. F. Beebe. Also, check
6214 for "L" suffix, and check that long double doesn't have
6215 worse range or precision than double, that mixed-mode
6216 arithmetic doesn't generate a diagnostic, that double
6217 constants fit in long double.
6219 2004-06-03 Kevin Ryde <user42@zip.com.au>
6221 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6222 malloc(0) and realloc(NULL,size).
6224 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6225 Bob Proulx.
6227 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6229 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6230 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6231 by Jim Meyering.
6233 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6235 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6236 can be rewritten using if-then-else. Suggested by Bruno Haible.
6238 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6240 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6241 Problem reported by Stepan Kasal.
6243 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6245 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6246 change). Patch reported by Ralf Wildenhues in
6247 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6249 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6250 function F exists if the compiler and linker let you compile an
6251 expression like (F != 0). Recent versions of GCC optimize away
6252 the reference to F in that case, since every function address must
6253 be nonzero, so the link succeeds even if F does not exist.
6254 Problem reported by Manu in
6255 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6257 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6258 "Unix". Many uses changed.
6259 (Limitations of Builtins): Explain better why the ! command isn't
6260 portable.
6262 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6264 * lib/autom4te.in (Automake-preselections): Preselect
6265 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6267 2004-05-19 Kevin Ryde <user42@zip.com.au>
6269 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6270 referencing AC_FUNC_STRERROR_R.
6272 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6273 note pessimistic assumption when cross compiling.
6275 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6277 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6278 (until 2004) invoked subcommands with sh -e, contra POSIX.
6279 Reported by Kevin Ryde.
6281 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6283 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6284 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6285 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6286 `test -f " /usr/bin/grep"', which _always_ failed.
6287 (AC_PROG_SED): Ditto bogus PATH fix.
6288 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6289 requires that grep correctly supports _multiple_ `-e' options, rather
6290 than stating only that grep should accept `-e'.
6292 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6294 Port to C99, which requires that 'exit' be declared.
6296 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6297 to ensure that stdlib.h is included.
6298 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6299 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6300 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6301 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6302 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6303 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6304 when using 'exit' in a test; C99 requires that 'exit' be declared.
6306 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6308 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6309 now prefers 'grep' implementations that accept -e.
6310 (Limitations of Usual Tools): Describe problems of traditional
6311 egrep and fgrep with long input lines, and of traditional grep
6312 with -e.
6313 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6314 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6315 All callers changed. Append /usr/xpg4/bin to the PATH, for
6316 Solaris.
6317 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6318 the user with complaints about multiple -e options.
6319 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6320 Define it with AC_PROG_GREP.
6321 * configure.ac (AC_PROG_GREP): Add.
6322 * lib/freeze.mk (GREP): New macro.
6324 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6326 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6327 a possible candidate only after all others fail, rather than
6328 consulting it first. This improves backward compatibility by
6329 better reflecting the way shell selection occurred in previous
6330 versions of Autoconf, and should help to avoid triggering latent
6331 problems in other packages, such as the one in Automake where zsh
6332 is not handled robustly:
6333 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6334 Although it is not Autoconf's responsibility to work around
6335 problems in Automake, it nevertheless makes sense to avoid
6336 introducing unnecessary incompatibilites.
6338 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6339 Gary V. Vaughan <gary@gnu.org>
6341 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6342 how deeply nested we are when a suitable tool is found, set the
6343 ac_path_TOOL_found flag.
6344 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6345 nested we are in this macro. Break out of all 3 nested loops if
6346 ac_path_TOOL_found is set.

6353 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6355 * doc/autoconf.texi (Limitations of Make): Update documentation
6356 for `$<'. New entry `Long lines', based on a report from Simon
6357 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6358 paragraph about DJGPP, based on a mail from Richard Dawe.
6360 2004-04-20 Paul Eggert <eggert@twinsun.com>
6362 * tests/c.at (C keywords): Don't assume that GCC supports
6363 "restrict" and "inline", as sufficiently-old GCC versions do not
6364 (also, GCC configured to be in pedantic C89 mode does not).
6365 Problem reported by Sumit Pandya in:
6366 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6368 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6369 consider -g to work if it generates warnings when plain compiles
6370 don't. Problem reported by Braden McDaniel in:
6371 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6373 * doc/autoconf.texi (Slashes): New section, to document a problem

6382 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6384 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6385 best tool so far counter rely on the tool path variable name to
6386 avoid checks for one tool being affected by the results of running
6387 the length check on a previous tool.
6389 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6390 match expression argument, as different greps have different
6391 regular expression flavours.
6392 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6393 literals.
6394 (AC_PROG_EGREP): Pass 'EGREP$'.

6422 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6423 now defines HAVE_DECL_TZNAME if it is declared, when
6424 HAVE_STRUCT_TM_TM_ZONE is not defined.
6425 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6426 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6427 for HAVE_TZNAME.

6439 H. F. Beebe for the bug report.
6441 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6443 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6444 quoted -cmdline argument in Portland Group compiler (bug
6445 reported by Jeffrey J. Barteet).

6475 new macros.
6476 * NEWS: Document these changes.
6478 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6479 they make TeX hang up.

6484 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6485 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6486 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6487 vowel.

6507 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6509 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

6512 2004-02-18 Paul Eggert <eggert@twinsun.com>
6514 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6515 problem on QNX reported by Stephen Rasku in
6516 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6518 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6519 $(m4sh_m4f_dependencies); this removes a FIXME.
6520 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6521 (MAINTAINERCLEANFILES): Split into pieces,
6522 one per related section. Add $(srcdir)/wrapper.in.
6524 2004-02-09 Paul Eggert <eggert@twinsun.com>

6527 AC_SUBST provides no portable way to escape literal newlines.
6529 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6530 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6531 Darwin uses -lcrt2.o and there's little point to cataloging all
6532 the system variants. Partial fix reported by Andreas Waechter in:
6533 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
6534 for bug reported by Nelson H. F. Beebe in:

6549 the behavior of the third argument.
6550 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6551 correctly the behavior of the third argument. Document
6552 what the three macros that AU_DEFUN defines do. Fix
6553 warning message when the third argument includes $0

6557 Eric Sunshine <sunshine@sunshineco.com>
6558 Paul Eggert <eggert@twinsun.com>
6560 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

6564 (_AS_SHELL_FN_SPY): New macro.
6565 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

6572 (AS_REQUIRE_SHELL_FN): Require shell functions when
6573 it is used.
6574 (_AS_LINENO_WORKS): Put around braces, we do not
6575 trigger the bash bug anymore.
6576 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
6577 use AS_INIT_WITH_SHELL_FN.
6578 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6580 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6582 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

6586 (AU_DEFUN): Honor the third parameter, create autoupdate
6587 macros with AU_DEFINE.
6588 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,

6608 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6609 2003 (except 1997) to the list of copyright years. This undoes
6610 the 2003-05-22 change, which removed the older years from the list.
6611 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6613 2004-01-27 Gary V. Vaughan <gary@gnu.org>
6614 Albert Chin-A-Young <china@thewrittenword.com>

6620 AC_PROG_GREP.

6623 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6624 _AC_PROG_GREP, and AC_PROG_SED.
6625 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6626 longest input length accepted by a command.
6627 (AC_PROG_SED): Use it.
6628 * doc/autoconf.texi (Particular Programs): Document the changes.
6629 * NEWS: Updated.
6631 2004-01-27 Paul Eggert <eggert@twinsun.com>

6653 sources.
6655 2004-01-26 Paul Eggert <eggert@twinsun.com>
6657 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6658 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6659 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6660 not <inttypes.h>. Problem reported by Tim Mooney in
6661 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6662 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6663 Likewise.
6665 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6666 otherwise "make check" fails because it forbids cmp (I guess
6667 because cmp treats files as binary on DOS-like systems).
6669 * tests/mktests.sh: Update copyright date to 2004, since some tests
6670 have changed in 2004.
6672 2004-01-23 Gary V. Vaughan <gary@gnu.org>

6675 non-truncating sed or gsed program in PATH.
6676 * tests/acprograms.at: Add it.

6678 * NEWS: Updated.
6680 2004-01-15 Paul Eggert <eggert@twinsun.com>
6682 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6683 -std1 disables some useful extensions on Tru64. Problem reported
6684 by N. Lichtmaier in
6685 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6687 2004-01-14 Paul Eggert <eggert@twinsun.com>
6689 * doc/autoconf.texi (Programming in M4sh): Document that
6690 AS_MKDIR_P succeeds if the destination is a symbolic link
6691 to an existing directory.
6692 (Limitations of Usual Tools): Note that mkdir -p might not
6693 succeed on symlinks to directories.
6695 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6697 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6698 * bin/autoheader.in: Grammar fix in message.
6699 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6700 Test for dir before calling mkdir -p. (trivial changes)
6702 2004-01-13 Eric Blake <ebb9@byu.net>
6704 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6705 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6707 2004-01-10 Jim Meyering <jim@meyering.net>
6709 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6711 2004-01-09 Paul Eggert <eggert@twinsun.com>
6713 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6714 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6715 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6716 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6717 AC_COMPILE_IFELSE, since we now assume our caller invokes
6718 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6719 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6720 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6721 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6723 2004-01-07 Paul Eggert <eggert@twinsun.com>
6725 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6726 `"'...'"`, as it's confusing (and I suspect it may not work on
6727 some platforms). The code was incorrect anyway, as it assumed
6728 that \$ evaluated to itself in that context. Reported by
6729 Alexandre Duret-Lutz.
6731 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6733 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6734 and _LT_AC_TAGCONFIG.

6738 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6739 example, and add more examples. Reported by Eric Sunshine.
6741 2004-01-05 Paul Eggert <eggert@twinsun.com>
6743 * doc/autoconf.texi (Limitations of Usual Tools):
6744 Remove warning against "rm -fr" introduced yesterday; it
6745 was a false alarm.
6747 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6748 autoscan, autoupdate, ifnames): Don't use chmod -w.
6749 * lib/Makefile.am (autom4te.cfg): Likewise.
6750 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6751 "chmod -w".

6754 Paolo Bonzini <bonzini@gnu.org>
6756 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6757 by doing lineno substitution only on lines containing "$LINENO".
6759 2004-01-04 Paul Eggert <eggert@twinsun.com>
6761 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6762 Use "rm -f" to remove conftest.sed, not plain "rm".
6763 Bug reported by David Relson in
6764 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6766 * Makefile.am (autom4te-update):
6767 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6768 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6769 * doc/autoconf.texi (Guidelines): Likewise.

6784 -c -o might not work. From a suggestion by Kevin Ryde.
6785 (C Compiler, Generating Sources, Limitations
6786 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6787 Don't put '-o' after non-options, as POSIX doesn't allow this.
6788 Mention that cc's name might be gcc or c89 or whatever.
6790 2004-01-04 Kevin Ryde <user42@zip.com.au>

6855 * config/announce-gen (&print_locations, &print_signatures)
6856 (&sizes): New.
6857 Use them.
6858 No longer rely on Gnus to inline the list of signatures: compute
6859 them on the fly.
6861 2003-11-24 Akim Demaille <akim@epita.fr>
6863 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
6864 override some files.
6865 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
6866 From Debian Autoconf 2.58.
6868 2003-11-24 Akim Demaille <akim@epita.fr>

6906 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6907 than $target since the latter is not usual, add guidelines on when to

6912 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

6932 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

7065 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
7067 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
7068 cross test.
7070 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
7072 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
7073 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

7078 --help output.

7085 Problems reported by Eric Sunshine.
7087 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7089 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7090 -mGLOB_options_string stuff for Intel ifc, which can cause
7091 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
7092 pattern-matching instead of grep.
7094 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7096 * doc/autoconf.texi: Document new FC Fortran macros.

7110 -lcrt[01].o.
7112 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
7114 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7115 cache variable instead of $G77 to decide whether to include -O2,
7116 since $G77 is specific to Fortran 77.
7118 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7120 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
7121 free" flag. Re-order flags tested into rough order of popularity.
7123 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7125 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7126 arguments so that it can be used with syntax identical to
7127 AC_PROG_F77, and so that we can more easily decide to
7128 remove/deprecate the DIALECT optional argument in the future if it
7129 proves troublesome.
7130 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7131 non-freeform-supporting compilers. Document freeform flags.
7133 2003-10-03 Akim Demaille <akim@epita.fr>
7135 * configure.ac: Look for emacs, not macs.
7136 Reported by Eric Sunshine.
7138 2003-10-03 Akim Demaille <akim@epita.fr>
7140 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
7141 * bin/autoreconf.in (autoreconf_current_directory): Create the
7142 AUX_DIR if needed, for sake of automake --add-missing etc.
7143 Suggested by Alexandre Duret-Lutz.
7145 2003-10-03 Akim Demaille <akim@epita.fr>
7147 * configure.ac: Quotation and formatting changes.

7168 * lib/Autom4te/XFile.pm: Use Errno.
7169 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
7170 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
7172 2003-09-30 Akim Demaille <akim@epita.fr>
7174 * config/announce-gen (&print_news_deltas): Extracted from...
7175 (&print_changelog_deltas): here.

7177 (@news_file): this.
7179 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
7181 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
7182 have been created when invoking the compiler.

7194 Problem reported by Lars J. Aas in
7195 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
7196 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7197 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7198 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7200 2003-09-26 Akim Demaille <akim@epita.fr>
7202 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7203 directory for AC_CONFIG_COMMANDS' first argument exists.
7204 This makes valid the invocation of _AC_SRCPATH that follows.
7205 Reported by Eric Sunshine.
7206 * doc/autoconf.texi (Configuration Commands): Adjust.
7208 2003-09-26 Akim Demaille <akim@epita.fr>
7210 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7211 Reported by Ralf Corsepius.
7213 2003-09-26 Akim Demaille <akim@epita.fr>
7215 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
7216 arguments.
7217 Actually, use AU_ALIAS.
7218 From Bruno Haible.

7227 2003-09-26 Akim Demaille <akim@epita.fr>
7229 The test suite are sometimes assigning timings incorrectly.
7230 Reported by Henk Krus.
7231 Diagnosed by Nicolas Joly.
7233 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7234 AT_help_all.
7235 Instead of making AT_help a sequence of assignments to grow
7236 $at_help_all, just make AT_help_all be the growing contents of
7237 $at_help_all, and make a single assignment in...
7238 (AT_INIT): here.
7239 (at_times_skip): Flip the meaning and rename as...
7240 (at_times_p): this.
7241 (AT_INIT): When summarizing the test that ran, remove
7242 $at_times_file after use, and check it is present before trying to
7243 use it.
7245 2003-09-25 Akim Demaille <akim@epita.fr>
7247 Version 2.57d.
7249 * bin/Makefile.am (edit): Handle '@configure_input@'.
7250 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
7251 (ifnames): chmod -w.
7252 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7253 executables, not bin/ executables! Otherwise all the magic needed
7254 to find non installed files is turned off. This caused a failure
7255 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7256 as found in its environment (sent by tests/autoreconf): pointing
7257 to bin/autom4te that could not find its files.
7258 * tests/mktests.sh: Force the replacement of generated files, for
7259 the sake of "mv" program that are interactive when overwriting a
7260 -w file.
7261 * config/install-sh: Upgrade from CVS Automake.
7263 2003-09-23 Paul Eggert <eggert@twinsun.com>

7357 unchanged, and continues to support Fortran 77. New FC macros
7358 correspond to all the old F77 macros, with output variables FC,
7359 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7360 available dialect, but older dialects can be specified. There are
7361 new macros AC_FC_SRCEXT to set the source extension, and
7362 AC_FC_FREEFORM to accept free-form source files.

7400 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7401 are defaulted by AT_CHECK anyway.

7403 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7404 missing dnl.

7472 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7473 (&verbose): Remove.
7474 (&getopt): Adjust the note and verb channels, depending upon
7475 --verbose.

7477 * bin/autoupdate.in: Adjust.
7478 Use &verb, not &verbose.
7480 2003-08-21 Akim Demaille <akim@epita.fr>
7482 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7483 &parse_WARNINGS.

7488 2003-08-21 Akim Demaille <akim@epita.fr>
7490 First stab at preserving warnings between calls to autom4te,
7491 including when the cache is used.
7493 There are still several issues: (i) there are too many runs of m4
7494 (one for include, one for warnings, and some more), (ii) warnings
7495 spreading on several lines are not handled gracefully, (iii) the
7496 code meant to have the call stack display for errors does not work
7497 (its handling should move from m4 to autom4te).
7499 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7500 Use them.
7501 (@preselect): Add m4_warn.
7502 ($exit_status): Remove, use $exit_code.
7503 ($help): Use Autom4te::ChannelDefs::usage.
7504 (&handle_m4): No longer define the m4_warnings.
7505 At each run, extract and report the warnings.
7506 Always cache the result, including if the exit status is on
7507 failure, since if nothing changes, we should result in the same
7508 failure, hence we can use the cache.
7509 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7510 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7511 Remove.
7512 (m4_warn): Redefine as a do-nothing: it is its invocation that
7513 matters, as warnings are now reported via traces.
7514 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7515 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7516 the latter reveals calls to the former.
7518 Adjust the tests.
7520 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7522 2003-08-21 Akim Demaille <akim@epita.fr>
7524 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7525 Use them.
7527 2003-08-21 Akim Demaille <akim@epita.fr>
7529 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7530 forward order.
7531 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7532 (&parse_warnings): Accept a list of warning requests.
7533 (&usage): Return a string, not a side effect.
7534 (cross): New warning category.
7536 2003-08-21 Akim Demaille <akim@epita.fr>
7538 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7539 (&require_configure_ac): Accept an optional directory argument.
7540 ($configure_ac): Remove.
7541 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7542 (&catfile): Remove.
7543 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7544 * bin/autoscan.in: Adjust.
7546 2003-08-20 Akim Demaille <akim@epita.fr>
7548 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7549 Reported by Alexandre Duret-Lutz.
7551 2003-08-20 Akim Demaille <akim@epita.fr>
7553 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7554 * bin/autom4te: Adjust.
7555 In particular, be Autoconf tools are really silent when properly
7556 working, bind the verbosity of the 'note' channel to $verbose.
7557 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7558 (&xsystem, &contents): Remove, since they are exported by...
7559 * lib/Autom4te/FileUtils.pm: this.
7560 More perldoc.
7561 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7562 * lib/Autom4te/FileUtils.pm: here.
7564 2003-08-20 Akim Demaille <akim@epita.fr>
7566 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7567 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

7594 and m4_sinclude.
7596 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

7619 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7620 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7621 shorter column three. Add DESCRIPTION to log file content.
7623 2003-08-13 Derek Price <derek@ximbiot.com>
7625 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7626 output.

7637 (AT_CHECK_NOESCAPE): ...to this new macro.
7639 2003-07-31 Paul Eggert <eggert@twinsun.com>
7641 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7642 in Bash 2.01. Problem reported by Brian Gough in
7643 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

7653 inside '#ifndef __cplusplus'. Problem reported by
7654 Bob Friesenhahn.
7656 2003-07-06 Bill Clarke <llib@computer.org>
7658 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7659 'long', not 'int', for benefit of Sun's recent C++ compilers
7660 (trivial change). See:
7661 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7662 (This really should be 'intptr_t', not 'long', but that would
7663 take more work.)
7665 2003-06-25 Akim Demaille <akim@epita.fr>
7667 * lib/Makefile.am (autom4te.cfg): Make it read only.
7668 Depend on Makefile since it contains substitutions.

7677 From Gareth McCaughan.
7679 2003-06-23 Akim Demaille <akim@epita.fr>
7681 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7682 not all of them. This fixes 1. the fact that when testing
7683 Autoconf there are many many config.log, 2. the incorrect use of
7684 top_srcdir to find config.log.
7685 Don't mix the detailed output of failed test with the summary of
7686 failures. Rather, append detailed log afterwards.
7688 2003-06-23 Akim Demaille <akim@epita.fr>
7690 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7691 always run: output config.log on $at_group_log.

7753 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7754 changes.
7755 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7756 Autoconf nor Automake.
7757 (&contents): New, from Automake.
7758 PODify.
7760 2003-05-28 Paul Eggert <eggert@twinsun.com>
7762 * NEWS, doc/autoconf.texi (Particular Functions),
7763 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7764 is the inverse of localtime.
7766 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7768 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7769 (handle_exec_errors): New function. Work around $! being
7770 altered by WEXITSTATUS.
7771 (xqx, xsystem): Use handle_exec_errors.
7773 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7775 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7776 Do not call `_exit()', simply modify `$?'.
7777 (xsystem): Reset $! before running system, and check it afterward.
7778 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7779 63 for version mismatches.
7781 2003-05-23 Akim Demaille <akim@epita.fr>
7783 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7784 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7785 the middle of a line).
7786 * lib/m4sugar/m4sugar.m4: Likewise.
7787 Remove useless spaces in comments.
7789 2003-05-23 Akim Demaille <akim@epita.fr>
7791 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7792 exit 63, so that we (or Automake's "missing") can tell the
7793 difference with a plain failure.
7794 * doc/autoconf.texi (Notices): Adjust.
7796 2003-05-23 Akim Demaille <akim@epita.fr>
7798 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7799 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7800 White spaces cleanup.
7802 2003-05-22 Jim Meyering <jim@meyering.net>
7803 Paul Eggert <eggert@twinsun.com>
7805 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7806 Remove `#include <stdlib.h>' from the list; we should never
7807 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7808 resulting namespace pollution would cause other tests to fail.
7809 Configure scripts run with some older versions of g++ and HP's
7810 aCC would fail due to such an #include. Problems reported by
7811 Matthew Mueller in <http://bugs.debian.org/120704> and by
7812 Keith Bostic in
7813 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7814 In the test, use the test declaration before including <stdlib.h>,
7815 as that's closer to how it'll be used.
7817 2003-05-23 Akim Demaille <akim@epita.fr>
7819 * doc/autoconf.texi (Header Portability): ucred.h.
7820 From Ian Redfern.
7822 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7824 Overhaul Autotest's logging: generate separate log files
7825 in testsuite.dir/NNN/testsuite.log, and append them to
7826 testsuite.log instead of re-running the test verbosely.
7828 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7829 file descriptor, write 0 to at_status_file instead of setting
7830 at_status=0, initialize some new variables (at_status_file,
7831 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7832 to rerun the tests, instead append the at_group_log to the
7833 at_suite_log when a test fails.
7834 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7835 with the AS_MESSAGE_LOG_FD redirected to stdout.
7836 (AT_CLEANUP): save the output status in $at_status_file
7837 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7838 its original place.
7839 (AT_CHECK): since tests are run with a redirected stdout,
7840 and used to be re-run in verbose mode, turn some $at_verbose
7841 into echo, and don't redirect the output of testing stdout
7842 and stderr.
7844 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7845 the name of the debugging directory and information about
7846 its contents.
7848 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7850 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7851 parameter.

7921 Reported by Sander Niemeijer.
7922 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
7923 * doc/autoconf.texi (Default Includes): Document
7924 AC_INCLUDES_DEFAULT.
7926 2003-05-17 Akim Demaille <akim@epita.fr>

7963 and truncate.
7965 2003-05-06 Akim Demaille <akim@epita.fr>
7967 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7968 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7969 by aclocal.m4 is changed it might require the importing of another
7970 m4 extension file, i.e., aclocal must be run.
7972 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7973 (&parse_args): Use --force with aclocal if required and supported.
7974 (&autoreconf_current_directory): Use &run_aclocal.

7981 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7982 argument instead of a file name, so that the request file remains
7983 open during the whole autom4te run.
7984 ($icache_file): New.
7985 (&freeze): Lock the $icache_file.
7987 2003-04-29 Derek Price <derek@ximbiot.com>
7989 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7990 seperator with m4_append_uniq(). It doesn't work.
7991 (AT_CLEANUP): Add `;' to end of at_help_all.
7992 (AT_INIT): Allow --keywords to be specified more than once. When
7993 grepping $at_help_all for keywords, use the field and keyword
7994 seperators to ensure a complete keyword match. Alter at_prev handling
7995 to support the new --keywords behavior.
7997 2003-04-27 Karl Berry <karl@freefriends.org>
7999 * doc/autoconf.texi: Make the dir entries in the autoconf manual
8000 align better with others. I also made some of the individual
8001 entries on one line, for brevity and to make it easier for me to
8002 sort my dir-example file in the Texinfo distribution :).
8004 2003-04-12 Jim Meyering <jim@meyering.net>

8045 (TEXI2DVI): Make it --batch.
8047 2003-03-31 Derek Price <derek@ximbiot.com>
8049 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
8050 which removed the main loop.
8051 Thanks to Akim Demaille.
8053 2003-03-29 Akim Demaille <akim@epita.fr>
8055 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
8056 that starts a GUI.
8057 From Ilya Zakharevich.
8059 2003-03-29 Akim Demaille <akim@epita.fr>
8061 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The

8063 Suggested by Paul Eggert.
8065 2003-03-28 Akim Demaille <akim@epita.fr>
8067 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest

8069 header causes problems.
8071 2003-03-28 Akim Demaille <akim@epita.fr>
8073 * tests/torture.at (Configuring subdirectories): Require aclocal
8074 1.4, otherwise the test fails, as it does support configure.ac.
8075 This fixes the "test 40 failed" bug reports.
8077 2003-03-28 Akim Demaille <akim@epita.fr>
8079 * doc/autoconf.texi (C Compiler): `#line' portability.

8147 Tru64 make in the "target lookup" section.
8148 (Automake): Automake 1.5+ no longer requires special tools to be
8149 present on the developer's host.

8167 ${ac_make}.
8169 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
8170 When constructing paths with IFS=:, quote the path. If we're

8189 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
8190 to fix a mismatch between example and discussion.
8192 2003-02-24 Kevin Ryde <user42@zip.com.au>
8194 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8195 format starting with "-".
8197 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8199 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8200 is not portable inside Makefile.
8202 2003-02-20 Akim Demaille <akim@epita.fr>
8204 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8205 compiler says yeah, but preproc says nope, compiler is right.
8206 Conversely, prompt the reader to send a bug report to the
8207 maintainers of the package, not of Autoconf.
8209 2003-02-20 Klee Dienes <kdienes@apple.com>

8223 innocuous variant befor including <limits.h> or <assert.h>. This
8224 works around a bug reported by Albert Chin: HP-UX 11i
8225 (and earlier versions) have a <limits.h> that declares
8226 gettimeofday and many other functions.
8228 2002-12-03 Paul Eggert <eggert@twinsun.com>
8230 Version 2.57.
8232 * NEWS, configure.ac: Update version.

8236 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8237 nontrivially in main's body, so that f's external declaration is
8238 not optimized away in AIX. This should fix the bug reported by
8239 Martin Frydl in
8240 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8242 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8243 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8244 defined, to support freestanding compilers. This should fix the
8245 bug reported by Momchil Velkov in
8246 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8248 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

8262 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
8264 2002-11-15 Akim Demaille <akim@epita.fr>

8280 Update from masters.
8282 2002-11-14 Akim Demaille <akim@epita.fr>
8284 * Makefile.maint: Sync with Bison, i.e.:
8285 (po-check): Scan .l and .y files instead of the
8286 .c and the .h files that they generate. This fixes the bug
8287 reported by Tim Van Holder in:
8288 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8289 Look for N_ as well as for _. Try to avoid matching #define for
8290 N_ and _.
8291 From Paul Eggert.
8293 2002-11-14 Akim Demaille <akim@epita.fr>
8295 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8296 From Paul Eggert and Albert Chin-A-Young.
8298 2002-11-14 Akim Demaille <akim@epita.fr>
8300 * doc/autoconf.texi (C Compiler): Solitary backslashes.
8301 From Paul Eggert and Albert Chin-A-Young.
8303 2002-11-14 Kevin Ryde <user42@zip.com.au>
8305 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8306 than assigning in main, to avoid HP cc +O3 optimizing it away.
8308 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8310 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8311 option. Process --recheck after parsing all options. Pass -q
8312 option to configure on --recheck.
8313 (AC_OUTPUT): Pass -q from configure to config.status.
8314 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8315 arguments to record.
8316 * doc/autoconf.texi (config.status Invocation): Document
8317 config.status -q option.
8319 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

8322 Makefile.in if Makefile.am exists.

8344 Reported by Ezra Peisach.
8346 2002-11-05 Akim Demaille <akim@epita.fr>
8348 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8349 Remove.
8350 We _have_ to stop using the old compatibility scheme that tried to
8351 avoid useless backslashes because Libtool 1.4.3 contains a
8352 AC_DEFINE([error_t], [int],
8353 [Define to a type to use for \`error_t' if it is not
8354 otherwise available.])
8355 We _have_ to quote the single quote and backslashes with \. The
8356 old compatibility scheme saw that ` was backslashed, and therefore
8357 did not quote the single quote. Hence before this patch, Autoconf
8358 was not compatible with Libtool.
8360 2002-11-04 Paul Eggert <eggert@twinsun.com>
8362 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8378 from...
8379 (&autoreconf): here.
8380 ($help, $make, &parse_args, &autoreconf_current_directory):
8381 Support -m/--make.
8382 * doc/autoconf.texi (autoreconf Invocation): Adjust.

8400 2002-10-31 Akim Demaille <akim@epita.fr>
8402 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
8403 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8404 Make variable, not a shell variable.
8405 Suggested by Bruno Haible.
8407 2002-10-31 Akim Demaille <akim@epita.fr>
8409 * bin/autom4te.in (load_configuration): Reject #args out of any
8410 language.
8412 2002-10-31 Akim Demaille <akim@epita.fr>
8414 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

8426 Suggested by Tim van Holder.
8428 2002-10-29 Paul Eggert <eggert@twinsun.com>
8430 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
8431 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
8432 Problem reported by Bruno Haible.
8434 2002-10-29 Akim Demaille <akim@epita.fr>
8436 * doc/autoconf.texi (Header Templates): Put also in words what the
8437 pictures says to assist free style readers.
8438 (Customizing autom4te): s/--cache=/--cache /.
8440 2002-10-29 Akim Demaille <akim@epita.fr>
8442 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
8443 sys/wait.h.

8732 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
8733 /dev/null.
8734 Reported months ago by H. Merijn Brand.
8736 2002-10-17 Akim Demaille <akim@epita.fr>
8738 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
8740 2002-10-16 Paul Eggert <eggert@twinsun.com>
8742 * Makefile.maint (wget_files): Remove ansi2knr.c.
8743 (ansi2knr.c-url_prefix): Remove.
8745 2002-10-16 Akim Demaille <akim@epita.fr>
8747 Because of caching, some files that no longer exist and are no
8748 longer required can still cause errors.
8749 Reported by Alexandre Duret-Lutz.
8751 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8752 to frozen files in @ARGV, as @ARGV must remain being a list of
8753 files. Rather, at M4 call sites, use this...
8754 (&files_to_options): New function.
8755 (&freeze): Use &error.
8756 (&up_to_date): If a file that was included according to the cache
8757 is no longer there, then the output is out dated.
8758 (&main): Don't even check whether a file is up to date is anyway
8759 --force is given.
8760 * tests/tools.at (autom4te cache): New.
8762 2002-10-16 Akim Demaille <akim@epita.fr>
8764 * bin/autoconf.as: Kill dead options.
8765 * bin/autoupdate.in (&parse_args): Kill old options.
8766 * bin/autoreconf.in (&parse_args): Remove dead options.
8767 Factor some code.
8768 (&autoreconf): Report the directories we enter *and leave*, so
8769 that error messages can be easily located, and use GNU Make
8770 format, so that Emacs' compile mode understands us.
8771 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8772 if some file was changed instead of `print'.
8773 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
8774 (&parse_args): Remove the dead options.
8775 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
8776 autoheader's quiet mode.
8777 (AT_CHECK_AUTOUPDATE): Likewise.
8778 * tests/tools.at (autoupdate): Adjust.
8779 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8781 2002-10-11 Akim Demaille <akim@epita.fr>
8783 No longer use CPP to check for the existing of headers: use CC to
8784 check for compilability.
8786 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
8787 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
8788 (_AC_CHECK_HEADER_NEW): Rename as...
8789 (AC_CHECK_HEADER): this.
8791 * lib/autotest/general.m4 (AT_INIT): Include the failed test
8792 numbers in the Subject suggestion.
8794 2002-10-11 Akim Demaille <akim@epita.fr>
8796 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
8797 Suggest using AC_CHECK_DECLS instead.
8799 2002-10-11 Akim Demaille <akim@epita.fr>
8801 * tests/torture.at (AC_ARG_VAR): Have configure report the value
8802 of `precious'.
8804 2002-10-11 Akim Demaille <akim@epita.fr>
8806 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
8807 file name to enable parallel executions.
8808 From Sam Varshavchik.
8810 2002-10-08 Akim Demaille <akim@epita.fr>
8812 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8813 aclocal invocation, as Gettext macros might not be visible to
8814 aclocal.
8815 Instead of blindly running autopoint, scan configure.ac (not the
8816 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8817 Reported by Paul D. Smith.
8819 2002-10-08 Paul Eggert <eggert@twinsun.com>
8821 Work around problems found when POSIXLY_CORRECT=1 is set.
8822 None of this seems to have anything to do with POSIX, really,
8823 but it's how Perl getopt works.
8824 * bin/autom4te.in (parse_args): Configure GetOpt with
8825 "permute", too.
8826 * doc/autoconf.texi (Invoking autom4te):
8827 --warning -> --warnings.
8828 * lib/autom4te.in: --warning -> --warnings.
8830 2002-09-28 Akim Demaille <akim@epita.fr>
8832 * doc/autoconf.texi (autom4te.cache): New section.
8834 2002-09-28 Akim Demaille <akim@epita.fr>
8836 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
8837 (Automake-preselections): Update.
8838 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
8840 2002-09-28 Akim Demaille <akim@epita.fr>
8842 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
8843 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
8844 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8845 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
8847 2002-09-28 Akim Demaille <akim@epita.fr>
8849 * tests/torture.at (Configuring subdirectories): Be robust to
8850 users who use config.site to require for a cache: in this case,
8851 the two last configure runs, using two different sets of
8852 arguments, trigger a legitimate error.
8854 2002-09-28 Akim Demaille <akim@epita.fr>
8856 * tests/m4sh.at (Functions Support, Functions and return Support):
8857 New.
8859 2002-09-28 Akim Demaille <akim@epita.fr>
8861 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
8862 autoheader are Perl programs.
8863 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
8864 (autom4te): Specify that the sources are in the $srcdir.
8865 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8867 2002-09-28 Akim Demaille <akim@epita.fr>
8869 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
8870 (tm_zone): Move their rules to...
8871 * lib/autoconf/types.m4: here, using AN_ macros.
8872 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8873 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8874 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8875 * lib/autoconf/programs.m4: here.
8876 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
8877 (ETAGS_FOR_AUTOCONF): New.
8878 Use it.
8880 2002-09-28 Akim Demaille <akim@epita.fr>
8882 * lib/autoconf/autoscan.m4: New file.
8883 * lib/autoconf/autoconf.m4: Include it.
8884 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
8885 that were listed in the original autoscan.list.
8886 * lib/autoconf/headers.m4: Similarly with headers.
8887 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8888 (.m4.m4f): Don't pass --prepend-include, since that's done by
8889 tests/autom4te itself.
8890 * lib/autoscan/Makefile.am: Include freeze.mk.
8891 (autoscan.list): New target --this file is no longer a source.
8892 (autoscan.pre): New file.
8894 2002-09-28 Akim Demaille <akim@epita.fr>
8896 * bin/autoscan.in (@kinds): Make them singular.
8897 Adjust all uses.
8898 (&init_tables): When --debug, report the list of rules to ease
8899 tracking changes in autoscan.list.
8900 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8902 2002-09-28 Akim Demaille <akim@epita.fr>
8904 * lib/autoscan/functions, lib/autoscan/headers,
8905 * lib/autoscan/identifiers, lib/autoscan/makevars,
8906 * lib/autoscan/programs: Merge into...
8907 * lib/autoscan/autoscan.list: this.
8908 * bin/autoscan.in (&init_tables): Adjust.
8910 2002-09-28 Akim Demaille <akim@epita.fr>
8912 * lib/autoscan/functions, lib/autoscan/headers,
8913 * lib/autoscan/identifiers, lib/autoscan/makevars,
8914 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8915 `functions' line is now prefixed with `function:'.
8916 * bin/autoscan.in (&init_tables): Adjust.
8918 2002-09-28 Akim Demaille <akim@epita.fr>
8920 From now on, autoscan files must always map a macro name to a
8921 word: there is no `default' macro for autoscan.
8923 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8924 all.
8925 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8926 explicit.
8928 2002-09-28 Akim Demaille <akim@epita.fr>
8930 * bin/autoscan.in (%c_keywords): Remove.
8931 (&used): Keep only track of the words we might be interested in.
8932 (&output_kind): It is no longer needed to look for non active
8933 checks.
8935 2002-09-27 Akim Demaille <akim@epita.fr>
8937 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
8938 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
8939 * lib/autoscan/functions: Adjust.
8940 * doc/autoconf.texi (Particular Functions): Adjust.
8942 2002-09-27 Akim Demaille <akim@epita.fr>
8944 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8945 from /tmp.
8946 Thanks to Bill Moseley and Paul Eggert.
8947 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8948 the tmpdir must be created.
8949 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8950 dir be in the build tree, instead of $TMPDIR.
8952 2002-09-27 Akim Demaille <akim@epita.fr>
8954 * bin/autoscan.in: Improve the comments.
8955 (&parse_args): Drop obsolete undocumented options.
8956 (&output_kind): Output warnings.
8957 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
8958 (getwd): Trigger a warning.
8960 2002-09-26 Akim Demaille <akim@epita.fr>
8962 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8963 Reported by Ralf Corsepius.
8964 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8966 2002-09-26 Akim Demaille <akim@epita.fr>
8968 Single suffix rules and seperated dependencies are not portable.
8970 * doc/autoconf.texi (Installation Directory Variables): Update.
8971 (Limitations of Make): Some about `Single Suffix Rules and
8972 Separated Dependencies'.
8973 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8974 (ifnames, autoscan, autom4te): Un-factor into several rules.
8976 2002-09-25 Paul Eggert <eggert@twinsun.com>
8978 * BUGS (Interoperability bugs): New section. Mention libtool
8979 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8981 2002-09-24 Paul Eggert <eggert@twinsun.com>
8983 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8984 make handles suffix-rules differently from GNU make.
8986 * bin/Makefile.am (SUFFIXES, .in): Remove.
8987 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8988 Move the body of the old .in rule here.
8990 2002-09-16 Akim Demaille <akim@epita.fr>
8992 i960 compilers create `b.out' files by default.
8993 Reported by Ralf Corsepius.
8995 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8996 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8998 2002-09-13 Paul Eggert <eggert@twinsun.com>
9000 * doc/autoconf.texi (Particular Headers): Remove obsolete
9001 reference to `struct timezone' in the description of
9002 AC_HEADER_TIME.
9004 2002-09-13 Akim Demaille <akim@epita.fr>
9006 Version 2.54.
9008 * config/config.sub, config/config.guess: Update.
9009 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
9010 * Makefile.am: Adjust.
9012 2002-09-13 Akim Demaille <akim@epita.fr>
9014 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
9015 reading config.log when the compiler is rejected.
9016 Suggested by Guido Draheim.
9018 2002-09-13 Akim Demaille <akim@epita.fr>
9020 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
9021 (chdir_init) might hang when stat'ing mounted directories.
9022 Reported by Vance Shipley.
9024 2002-09-12 Akim Demaille <akim@epita.fr>
9026 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
9027 the lists.
9029 2002-09-12 Akim Demaille <akim@epita.fr>
9031 * doc/autoconf.texi (Defining Symbols): Present two different
9032 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
9033 difference between 1 argument calls, and 2-3 argument calls.
9035 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
9037 * doc/autoconf.texi: Review grammar and punctuation.
9039 2002-09-11 Paul Eggert <eggert@twinsun.com>
9041 * doc/autoconf.texi: Fix minor formatting, spelling, and
9042 grammatical typos.
9043 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
9044 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
9045 is obsolescent.
9047 2002-09-11 Akim Demaille <akim@epita.fr>
9049 * doc/autoconf.texi (Questions): Rename as...
9050 (FAQ): this.
9051 (Defining Directories): New.
9053 2002-09-09 Akim Demaille <akim@epita.fr>
9055 * doc/autoconf.texi (Making testsuite Scripts): Update.
9056 Suggested by Nishio Futoshi.
9058 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
9060 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
9061 plain `@' is wanted.
9063 2002-09-09 Akim Demaille <akim@epita.fr>
9065 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
9066 `duplicates', since the algorithm was too naive and could keep
9067 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
9068 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9069 Reported by Ralf Corsepius.
9070 * tests/torture.at (Configuring subdirectories): Exercise these
9071 cases.
9073 2002-09-09 Akim Demaille <akim@epita.fr>
9075 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
9076 looking for a replacement file.
9077 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9078 directory is relative.
9079 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9080 directory definition.
9081 Reported by Andreas Schwab and Jim Meyering.
9083 2002-09-06 Akim Demaille <akim@epita.fr>
9085 * doc/autoconf.texi (Setting Output Variables): Clarify what
9086 precious variables are.
9087 Suggested by Pontus Skoeld.
9089 2002-09-05 Akim Demaille <akim@epita.fr>
9091 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9092 (ifnames, autoscan, autom4te): Since we don't only depend on
9093 configure.ac variables (such as VERSION etc.), but also on prefix
9094 and so forth, depend on Makefile, not configure.ac.
9095 Reported by Alexandre Duret-Lutz.
9096 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9098 2002-09-05 Kevin Ryde <user42@zip.com.au>
9100 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9101 doesn't seem to be confined to ia64, just say "some versions".
9103 2002-09-04 Akim Demaille <akim@epita.fr>
9105 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9106 Automake 1.6c.
9107 * Makefile.am (maintainer-clean-local): Remove.
9108 (MAINTAINERCLEANFILES): Remove COPYING.
9110 2002-09-03 Paul Eggert <eggert@twinsun.com>
9112 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9113 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9114 Brinkmann.
9116 2002-09-03 Akim Demaille <akim@epita.fr>
9118 * configure.ac: Bump to 2.53d.
9119 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9120 as of today, on Automake's team suggestion.
9122 2002-09-03 Akim Demaille <akim@epita.fr>
9124 Version 2.53c.
9126 2002-09-02 Akim Demaille <akim@epita.fr>
9128 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9129 SITE_MACRO_DIR.
9130 * configure.ac: Disable SITE_MACRO_DIR.
9132 2002-09-02 Jim Meyering <meyering@lucent.com>
9134 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9135 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9136 Also, tweak grammar: s/make sure to/be sure to/.
9138 2002-09-02 Paul Eggert <eggert@twinsun.com>
9140 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9141 directory names are generally preferable to physical names.
9143 2002-09-02 Akim Demaille <akim@epita.fr>
9145 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9146 Reported by Raja R. Harinath.
9147 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9148 * bin/autoupdate.in: Use error instead of die.
9150 2002-09-01 Paul Eggert <eggert@twinsun.com>
9152 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9153 ordinary shell concatenation rather than echo+tr+sed command that
9154 runs afoul of a long-line-related sed bug in Solaris 8.
9156 * bin/autoheader.in (parse_args): --warning -> --warnings.
9158 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9159 stdout, as traditional "ls" does.
9160 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9161 _AC_COMPILER_EXEEXT_O): Likewise.
9162 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9164 * bin/autoconf.as: Add --prepend-include option. This patch was
9165 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9166 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9168 * bin/autoconf.in, configure: Regenerate.
9170 * doc/autoconf.texi (Special Shell Variables): Mention
9171 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9173 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9174 MAILPATH and set PS1, PS2, PS4 to default values, to work
9175 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9176 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9177 the Autoconf documentation specifies; fall back to "unset" only if
9178 this fails. Use a shell for-loop for this rather than an m4 loop,
9179 to shorten the output script.
9181 2002-08-30 Paul Eggert <eggert@twinsun.com>
9183 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9184 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9185 for the CDPATH problem. Document PWD.
9186 (Limitations of Builtins): Document the problem that "cd $foo" and
9187 "ls $foo" may refer to different directories in shells conforming
9188 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9189 example, since the old example is now out of date.
9191 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9192 FOO" and "ls FOO" talk about different directories; this catches
9193 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9194 spaghetti.
9196 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9197 of rolling our own unset.
9198 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9199 in practice we needn't worry about CDPATH if unset doesn't work.
9201 * Makefile.in, aclocal.m4, bin/Makefile.in,
9202 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9203 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9204 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9205 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9206 tests/Makefile.in: Regenerate with Automake 1.6.3.
9208 * config/config.guess, config/config.sub, config/mkinstalldirs:
9209 Update.
9211 * configure: Regenerate with self.
9213 2002-08-30 Kevin Ryde <user42@zip.com.au>
9215 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9216 default output.
9218 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9220 * bin/autom4te.in (Request::load): Correctly test for "do" read
9221 failure.
9223 2002-08-29 Akim Demaille <akim@epita.fr>
9225 * lib/Autom4te/General.pm (&xqx): New.
9226 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9227 hand, which is not portable.
9228 (&error): New.
9229 * bin/autom4te.in: Use them.
9230 Use &error instead of die.
9231 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9232 Adjust.
9234 2002-08-17 Paul Eggert <eggert@twinsun.com>
9236 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9237 default list of compilers to try, since it was long ago superseded
9238 by the ksh fc builtin. Suggested by Steven G. Johnson.
9240 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9242 * doc/autoconf.texi (Invoking autom4te): End the option table,
9243 fixing a bug introduced by the previous patch.

9259 * doc/install.texi: Include copyright symbol in copyright notice.
9261 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9262 Replace with:
9263 (AM_MAKEINFOFLAGS): New macro.
9264 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9265 * Makefile.am (INSTALL): Use the new macros.
9266 Use -o rather than --output, since "missing" does not grok --output.
9268 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9270 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9271 comments do not always work. Never trust the exit status of
9272 `make -k'.
9274 2002-07-24 Kevin Ryde <user42@zip.com.au>
9276 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9277 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.

9283 apparently treats PATH="nonexistent" as if it contained ".".
9284 Bug reported by Stefan `Sec' Zehl.
9286 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

9408 so that Emacs setups GNU style for perl-mode and cperl-mode.
9410 2002-06-27 Paul Eggert <eggert@twinsun.com>
9412 * config/install-sh: Quote $src. Prefer || to test's -o option,
9413 as per "Limitations of Builtins".
9414 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
9415 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9417 * tests/mktests.sh: Use grep instead of fgrep, as per
9418 "Limitations of Builtins".
9420 2002-06-15 Paul Eggert <eggert@twinsun.com>
9422 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,

9424 so that we consistently test the just-built programs.
9425 * tests/wrappl.as: Likewise.
9427 2002-06-12 Paul Eggert <eggert@twinsun.com>
9429 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

9433 * bin/autoreconf.in (autoconf, autoheader): Likewise.
9434 * bin/autoscan.in (autom4te): Likewise.

9437 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
9438 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
9439 on Solaris 2.5.1.
9441 2002-06-11 Andreas Schwab <schwab@suse.de>

9445 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9447 * bin/autom4te.in ($cache): Don't define using `$me', the name
9448 of the cache should not depend on the name under which autom4te
9449 was installed.
9451 2002-06-07 Akim Demaille <akim@epita.fr>
9453 * tests/tools.at (autoconf: forbidden tokens, basic)

9462 2002-06-07 Akim Demaille <akim@epita.fr>

9475 2002-06-07 Akim Demaille <akim@epita.fr>
9477 * bin/autom4te.in (warn_forbidden): When rejecting a token,
9478 suggest m4_pattern_allow.
9479 Suggested by Adam J. Richter.
9481 2002-06-07 Akim Demaille <akim@epita.fr>
9483 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

9485 (AC_CONFIG_LIBOBJ_DIR): New.
9486 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

9542 2002-05-22 Paul Eggert <eggert@twinsun.com>
9544 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77

9546 Kate Hedstrom.
9547 * NEWS: Document the above.
9548 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.

9552 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9553 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9554 This improves on an earlier suggestion by H. Peter Anvin.
9556 2002-05-16 Paul Eggert <eggert@twinsun.com>
9558 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9559 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9560 Both macros now accept an optional source-dir arg.
9561 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9563 * NEWS: Document this.
9564 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9566 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9567 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9568 not for GNU extensions; this undoes part of the 2000-11-03 change,
9569 reverting to 2.13-compatible behavior.
9570 Add new optional argument DIR.
9571 (AC_FUNC_FNMATCH_GNU): New macro.
9573 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9575 2002-05-08 Paul Eggert <eggert@twinsun.com>
9577 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9578 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9579 and it causes a 'test' syntax error if it fails.
9580 Bug reported by Stephen Gildea.
9582 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9583 If prototypes are supported, use them to check this at compile-time,
9584 instead of trying to check it at run-time. If we must do a run-time
9585 check, assume that setvbuf is standard when cross-compiling, as
9586 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9587 Bug reported by Paul D. Smith.
9589 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9590 argument specifying location of getloadavg.c. This removes a
9591 FIXME. This idea was taken from Jim Meyering's implementation in
9592 textutils.
9593 * doc/autoconf.texi (Particular Functions): Document this.
9594 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9595 that's what the code does; this fixes a bug reported by
9596 Paul D. Smith.
9598 2002-05-03 Akim Demaille <akim@epita.fr>
9600 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9601 autopoint instead of gettextize.
9602 ($uses_alocal): Rename as...
9603 ($uses_aclocal): this.
9604 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9605 Suggested by Bruno Haible.
9607 2002-05-03 Akim Demaille <akim@epita.fr>
9609 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9611 2002-04-29 Paul Eggert <eggert@twinsun.com>
9613 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9614 files to be 1 second older; just set them to be the same time.
9615 Also, sleep 1 second after the first aclocal, to work around
9616 problems with sub-second time stamps on the input files.
9618 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9620 * doc/autoconf.texi: Mention "set -e -x" lossage
9621 under node "Limitations of Builtins".
9623 2002-04-29 Akim Demaille <akim@epita.fr>
9625 * doc/install.texi: Better wording for setting variables when
9626 running configure.
9627 From Christian Cornelssen.
9629 2002-04-29 Akim Demaille <akim@epita.fr>
9631 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9632 of lack of $LINENO support, then the test will compare the $LINENO
9633 in testsuite vs. the lineno in the test file. This is wrong, of
9634 course.
9635 Be sure to protect it.
9636 Reported by Patrick Welche.
9638 2002-04-25 Akim Demaille <akim@epita.fr>
9640 * doc/autoconf.texi (Obsolete Macros): Typo.
9641 Reported by Vladimir Volovich.
9643 2002-04-25 Akim Demaille <akim@epita.fr>
9645 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9646 than some of the input files, hence, on the second run of aclocal,
9647 if some of its input are younger, make them older.
9648 Suggested by Paul Eggert.
9650 2002-04-25 Akim Demaille <akim@epita.fr>
9652 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9653 Thanks to Paul Eggert.
9655 2002-04-25 Akim Demaille <akim@epita.fr>
9657 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9658 and ac_subst_vars be sh variables containing the list of
9659 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9660 DEFAULT diversion.
9661 (_AC_INIT_PREPARE): Use them to log them.
9662 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9663 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9664 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9665 _AC_SUBST_FILES and _AC_SUBST_VARS.
9666 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9668 2002-04-24 Akim Demaille <akim@epita.fr>
9670 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9671 autoheader, so that automake does not complain about a missing
9672 config.h.in that was to be created.
9674 2002-04-23 Akim Demaille <akim@epita.fr>
9676 * bin/autoheader.in (parse_args): --warning takes an argument.
9677 Fixes PR/220.
9679 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9681 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

9690 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
9692 2002-04-22 Akim Demaille <akim@epita.fr>
9694 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
9695 comma.
9696 Reported by Gregory Giannoni.
9698 2002-04-22 Akim Demaille <akim@epita.fr>
9700 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
9701 Fixes false failures on Darwin.
9703 2002-04-21 Paul Eggert <eggert@twinsun.com>
9705 * TODO, bin/autoupdate.in, doc/autoconf.texi,
9706 lib/autoconf/general.m4, lib/autoconf/libs.m4,
9707 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,
9708 tests/tools.at: Minor spelling and grammar fixes.
9710 2002-04-20 Paul Eggert <eggert@twinsun.com>
9712 * doc/autoconf.texi (Shell Substitutions): Fix typos in yesterday's
9713 ZSH_VERSION fixes. Bug reported by Raja R Harinath.
9714 * lib/autotest/general.m4 (AT_INIT): Likewise.
9715 * tests/atgeneral.m4 (AT_INIT): Likewise.

9725 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
9726 Minor spelling and grammar fixes.
9728 * doc/autoconf.texi: Follow the outline suggested in the GNU
9729 Sample Texts sections of the Texinfo 4.2 manual. Most
9730 importantly, this makes sure that the copyright notices appear in
9731 all output formats. You probably need Texinfo 4.2 to generate
9732 the manual now.
9734 Fix some bugs when using "$@" when there might be zero positional
9735 arguments in cases where this matters.
9737 * bin/autoconf.as: Rewrite so that the problem does not come up.

9751 * lib/autotest/general.m4 (AT_INIT):
9752 Use Zsh alias to work around problem.
9753 * tests/atgeneral.m4 (AT_INIT): Likewise.
9755 * tests/c.at: We can't have zero arguments, so remove workaround
9756 that is not portable to Zsh.
9758 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9760 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9761 from aclocal.m4 too.
9763 2002-04-12 Akim Demaille <akim@epita.fr>
9765 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
9767 2002-04-10 Akim Demaille <akim@epita.fr>
9769 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9770 workaround for ${1+"$@"}.
9771 * doc/autoconf.texi (Shell Substitutions): Explain it.
9772 From Oliver Kiddle and Peter Stephenson.
9774 Have M4sh perform minimal shell sanitizing.
9776 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9777 part into...
9778 (_AS_PREPARE): this new macro.
9779 (AS_PREPARE): New.
9780 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9781 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9783 Adjust Autoconf and Autotest.
9785 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9786 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9787 * lib/autotest/general.m4 (AT_INIT): Likewise.
9788 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9789 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9790 AS_SHELL_SANITIZE.
9792 Use this M4sh to generate Autoconf's shell scripts.
9794 * tests/wrapsh.as: New, precursor of wrapsh.in.
9795 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9796 on Autotest and M4sh.
9797 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9798 (wrapsh.in): New target.
9799 * bin/autoconf.as: New, precursor of autoconf.in.
9800 (autoconf.in): New target.
9802 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

9805 with indented comments in rules.
9807 2002-04-09 Andreas Schwab <schwab@suse.de>
9809 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9810 ac_top_builddir when setting ac_abs_top_builddir.
9812 2002-04-06 Kevin Ryde <user42@zip.com.au>
9814 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9815 (Portable Shell): Cross reference to Systemology.
9817 2002-04-05 Akim Demaille <akim@epita.fr>
9819 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9820 directories when descending in a SUBDIRS.
9821 Reported by Ezra Peisach.
9823 2002-04-04 Andreas Schwab <schwab@suse.de>
9825 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9826 contains no literal separators.
9828 2002-04-03 Akim Demaille <akim@epita.fr>
9830 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9831 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9832 Use dnl, not the KILL diversion.
9833 Extracted from...
9834 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9835 (AC_CONFIG_LINKS): here.
9836 Adjust.
9837 Don't use the KILL diversion, as it kills spurious output, which
9838 results in failures being hidden.
9839 Use m4_defn where appropriate.
9840 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9841 after the second argument.
9842 Use m4_defn.
9843 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9844 syntax, as it is provided by M4sugar.
9845 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9847 2002-04-03 Andreas Schwab <schwab@suse.de>
9849 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9850 expanded if $# <= 2.
9852 * bin/autoreconf.in (autoreconf): Run automake after rerunning
9853 aclocal.
9855 2002-04-03 Akim Demaille <akim@epita.fr>
9857 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
9858 (_AC_COMPILER_EXEEXT_REJECT): New.
9859 Also recognize *.bb and *.bbg as compilation byproducts.
9860 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9861 (_AC_COMPILER_OBJEXT): Use them.
9862 Fixes Debian #138666.
9864 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9866 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9868 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9869 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.

9872 (AC_C_CONST): Same.

9882 _AS_MKDIR_P_PREPARE.
9884 2002-03-28 Kevin Ryde <user42@zip.com.au>
9886 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9887 to avoid versions of HP C which don't allow that.
9889 2002-03-27 Paul Eggert <eggert@twinsun.com>
9891 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9892 (AS_SHELL_SANITIZE): Invoke it.
9893 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9895 2002-03-26 Akim Demaille <akim@epita.fr>
9897 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9899 2002-03-26 Akim Demaille <akim@epita.fr>
9901 * doc/autoconf.texi (Introduction): The GNATS base moved.
9903 2002-03-25 Paul Eggert <eggert@twinsun.com>
9905 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9906 as POSIX requires, as it doesn't work with Zsh.
9907 * doc/autoconf.texi (Assignments): Document the problem.
9909 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9911 * doc/autoconf.texi (Limitations of Make): Mention more issue
9912 about VPATH, overriding of macros in sub-makes, and handling of
9913 SHELL.
9915 2002-03-21 Paul Eggert <eggert@twinsun.com>
9917 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9918 problem with here-document buffer boundaries.
9920 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9921 when reinvoking the shell, to work around problems with installers
9922 who put strange things like "cd" commands in their environments.
9924 2002-03-19 Akim Demaille <akim@epita.fr>
9926 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9927 From Aaron Ucko.
9929 2002-03-19 Akim Demaille <akim@epita.fr>
9931 * bin/autoscan.in (scan_file): Specify the location in `&used'
9932 invocations.
9933 From Nicolas Joly.
9935 2002-03-19 Akim Demaille <akim@epita.fr>
9937 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9938 From Nishio Futoshi.
9940 2002-03-19 Akim Demaille <akim@epita.fr>
9942 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9944 2002-03-18 Paul Eggert <eggert@twinsun.com>
9946 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9947 (Limitations of Usual Tools): Add mkdir section.
9949 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9950 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9951 back on AS_DIRNAME to compute prefixes otherwise; this is
9952 roughly what mkinstalldirs does. That way, we need not have
9953 our own filename disassembler. The old disassembler did not
9954 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9956 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9957 Create at_test_all by a series of assignments,
9958 not by a single assignment of a long string. The latter causes ksh
9959 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9960 presumably because of a buffer overrun.
9962 2002-03-14 Paul Eggert <eggert@twinsun.com>
9964 * lib/autotest/general.m4 (at_times_skip):
9965 Renamed from at_times. Now a boolean.
9966 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9967 says 'times: not found'.
9969 2002-03-14 Akim Demaille <akim@epita.fr>
9971 * bin/autoreconf.in (&study_gettextize): New.
9972 (&autoreconf): Handle newest gettextize.
9973 Rerun aclocal if needed.
9974 Suggested by Andreas Schwab.
9976 2002-03-13 Akim Demaille <akim@epita.fr>
9978 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9980 2002-03-13 Akim Demaille <akim@epita.fr>
9982 * doc/autoconf.texi (Header Portability): New.
9983 Add information about stdint.h and inttypes.h from Paul Eggert.
9985 2002-03-13 Akim Demaille <akim@epita.fr>
9987 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9988 -p'.
9989 From Bob Proulx.
9991 2002-03-12 Akim Demaille <akim@epita.fr>
9993 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9994 m4_require.
9996 2002-03-11 Andreas Schwab <schwab@suse.de>
9998 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9999 does not do it if --with-lispdir is given.
10001 2002-03-08 Akim Demaille <akim@epita.fr>
10003 Version 2.53.
10005 2002-03-08 Akim Demaille <akim@epita.fr>
10007 * doc/autoconf.texi (Subdirectories): Clarify that the
10008 subdirectory should exist.
10010 2002-03-08 Akim Demaille <akim@epita.fr>
10012 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
10014 2002-03-08 Akim Demaille <akim@epita.fr>
10016 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
10017 aliases the actual variables, and modifications of the former
10018 affect the latter.
10020 2002-03-08 Akim Demaille <akim@epita.fr>
10022 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
10023 because of C-c: have m4 output in tmp files, then mv them.
10025 2002-03-08 Akim Demaille <akim@epita.fr>
10027 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
10028 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
10029 * bin/ifnames.in: Copyright update.
10031 2002-03-08 Akim Demaille <akim@epita.fr>
10033 * doc/autoconf.texi (Invoking autom4te): New.
10035 2002-03-05 Akim Demaille <akim@epita.fr>
10037 * doc/autoconf.texi (Specifying Names): Clarification suggested by
10038 Kevin Ryde.
10040 2002-03-05 Akim Demaille <akim@epita.fr>
10042 Version 2.52i.
10044 2002-03-04 Akim Demaille <akim@epita.fr>
10046 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
10047 * lib/autoconf/general.m4 (AC_INIT): More informative error
10048 message for LIBOBJ.
10050 2002-03-04 Akim Demaille <akim@epita.fr>
10052 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
10053 parallel builds.
10055 2002-03-04 Akim Demaille <akim@epita.fr>
10057 * doc/autoconf.texi (Transforming Names): Equality between target
10058 and host is irrelevant.
10059 (Specifying Names, Canonicalizing): Remove all references to the
10060 backward compatibility hooks. Rather, collect them all into...
10061 (Hosts and Cross-Compilation): this new section.
10062 * doc/install.texi (System Type): Ditto.
10063 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
10064 that `--host' implies cross-compilation.
10066 2002-03-04 Akim Demaille <akim@epita.fr>
10068 * doc/autoconf.texi (Evaluation Macros): New.
10069 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10070 useless.
10071 (_m4_foreach): Define the variant with immediate evaluation so
10072 that it contains exactly the items, not an expression which
10073 evaluation is the current item.
10074 (m4_re_string, m4_re_word): Don't over quote them.
10076 2002-03-04 Akim Demaille <akim@epita.fr>
10078 Instead of having stacking `shift's evaluated at the end, let
10079 `foreach' loops immediately evaluate them.
10081 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10082 $*. This is the n-th time I change my mind, but hopefully this is
10083 the last...
10084 (m4_lquote): New.
10085 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10086 efficient.
10087 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10088 it was only a hack for m4_text_wrap.
10089 (m4_car2): Remove, replaced by...
10090 (m4_cdr): New.
10091 (_m4_foreach): Adjust.
10092 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10093 m4_bpatsubst for clarification.

10137 Fix Autoconf PR/209.
10138 Also reported by Frank Denis.

10142 2002-02-07 Akim Demaille <akim@epita.fr>
10144 Fix Autoconf PR/207:
10145 AC_PREFIX_PROGRAM fails with dashed program names
10147 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
10148 variable when looking for the prefix program.
10149 Now it also works for shell variables.

10186 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

10208 * bin/autom4te.in (&parse_args): Implement `frozen files are
10209 optional are the sum of the previous files on the command line'.
10210 Also, pass `--reload-state=' on them, so...
10211 (handle_m4): don't.
10212 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10213 (M4sh): Rely on M4sugar.
10214 (Autotest, M4sh, M4sugar): Use frozen files.
10216 2002-01-31 Akim Demaille <akim@epita.fr>
10218 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
10219 * doc/autoconf.texi (Initializing configure): Adjust.
10221 2002-01-30 Akim Demaille <akim@epita.fr>
10223 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
10224 alphanumeric to `-' instead of `_'.
10226 2002-01-30 Akim Demaille <akim@epita.fr>
10228 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10229 for plain code, the other for cross-compilation code. The latter
10230 is now run with GCC only.
10231 * doc/autoconf.texi (Compilers and Preprocessors): New.
10233 2002-01-30 Akim Demaille <akim@epita.fr>
10235 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
10236 values.
10237 * doc/autoconf.texi (Initializing configure): Explain how to
10238 change AC_INIT default values.
10240 2002-01-29 Akim Demaille <akim@epita.fr>
10242 * tests/torture.at (Configuring subdirectories): Use configure.in,
10243 so that aclocal 1.4 works.
10244 Reported by Alexandre Duret-Lutz and Larry Schmitt.
10246 2002-01-28 Akim Demaille <akim@epita.fr>
10248 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10249 needs an argument.
10251 2002-01-28 Akim Demaille <akim@epita.fr>
10253 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10254 AUTOTEST_PATH *after* it was set.
10255 Don't put `.' in the PATH: the user should be precise and `./' if
10256 needed. In addition, given that the test suite does some `cd', if
10257 `.' is in the path, the `tested programs' sections will report
10258 programs found in the test suite's directory, while during the
10259 tests (performed in their own directory), these programs are no
10260 longer visible. In other words, the results is confusing and
10261 useless.
10262 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10264 2002-01-24 Akim Demaille <akim@epita.fr>
10266 Version 2.52g.
10268 2002-01-24 Akim Demaille <akim@epita.fr>
10270 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
10271 * doc/autoconf.texi: Finally add Akim as an author.
10273 2002-01-24 Akim Demaille <akim@epita.fr>
10275 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
10276 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
10277 Bourne. Use /bin/sh.
10278 From Andreas Buening.
10280 2002-01-24 Akim Demaille <akim@epita.fr>
10282 * config/config.guess, config/config.sub, config/texinfo.tex:
10283 Update from masters.
10285 2002-01-24 Akim Demaille <akim@epita.fr>
10287 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
10288 * config/auxdir.m4, config/cond.m4, config/depend.m4,
10289 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
10290 * config/missing.m4, config/sanity.m4, config/select.m4,
10291 * config/strip.m4: Remove, to ease sync'ing with any version of
10292 Automake.
10294 2002-01-24 Akim Demaille <akim@epita.fr>
10296 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
10297 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
10298 Reported by Geir Ove Myhr.
10300 2002-01-21 Akim Demaille <akim@epita.fr>
10302 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
10304 2002-01-21 Akim Demaille <akim@epita.fr>
10306 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10307 message on invalid options.
10308 * bin/autom4te.in (parse_args): Don't use
10309 Autoconf::General::getopt with non valid options.
10311 2002-01-17 Jim Meyering <meyering@lucent.com>
10313 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10314 $ac_cv_exeext so we don't use an old, invalid, cached value.
10316 2002-01-11 Akim Demaille <akim@epita.fr>
10318 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
10319 Meyering.

10321 limitation.

10325 2002-01-06 Akim Demaille <akim@epita.fr>
10327 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10328 package.m4, since is really depends upon configure.ac, not
10329 configure.
10330 * doc/autoconf.texi (testsuite Scripts): Adjust.
10331 * tests/Makefile.am (package.m4): New.
10332 EXTRA_DIST it since its a source.
10334 2002-01-06 Akim Demaille <akim@epita.fr>
10336 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10337 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10338 and PACKAGE_BUGREPORT from here...
10339 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10340 arguments.
10341 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10342 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10343 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
10344 * tests/tools.at (autoheader): Adjust.
10345 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
10347 2002-01-06 Akim Demaille <akim@epita.fr>

10351 2002-01-03 Akim Demaille <akim@epita.fr>
10353 * doc/autoconf.texi (Output): Improved wording regarding use of
10354 AC_OUTPUT.
10355 From Olly Betts.
10357 2001-12-18 Kevin Ryde <user42@zip.com.au>
10359 * doc/autoconf.texi (Function Portability): Add notes on sscanf
10360 sometimes needing writable input.
10362 2001-12-17 Jim Meyering <meyering@lucent.com>
10364 * doc/autoconf.texi (New Macros): Tweak wording.
10366 2001-12-14 Akim Demaille <akim@epita.fr>
10368 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10369 trailing files, don't apply `-rf' to files which might not be
10370 created by configure (core, core.*, and *.core), but just `rm -f'.
10371 Suggested by Jonathan Kamens.
10373 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10375 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
10377 2001-12-14 Akim Demaille <akim@epita.fr>
10379 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
10381 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
10383 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
10384 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
10385 abs_srcdir, top_srcpath to abs_top_srcdir.
10386 (_AC_OUTPUT_FILES): Adjust.
10387 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
10388 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
10389 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10391 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
10393 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
10394 C/Fortran linking on HP/UX, by extracting the Fortran library
10395 search path from the LPATH line in the $F77 -v output.
10397 2001-12-12 Kevin Ryde <user42@zip.com.au>
10399 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10400 forbidden file descriptors table.
10402 2001-11-26 Akim Demaille <akim@epita.fr>
10404 * bin/autoscan.in (%c_keywords): Build it at top level.
10405 Map to 1 in order to simplify its uses.
10407 2001-11-26 Akim Demaille <akim@epita.fr>
10409 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10410 Remove $filepath, useless.
10411 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10412 variables, they are really part of the tokens.
10413 Split the input line on spaces and then look for tokens.
10414 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10415 because of `lex$U.$(OBJEXT)'.
10416 (&scan_files): Use "@list" instead of join.
10417 * doc/Makefile.am (CLEANFILES): Add *.fns.
10419 2001-11-26 Akim Demaille <akim@epita.fr>
10421 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10422 Remove, replaced by...
10423 * tests/wrappl.in: Be common for all the Perl executables.
10424 In particular autoscan and autoheader want -I.
10425 * configure.ac: Adjust.
10426 * lib/autoscan/headers: errno.h is portable.
10428 2001-11-26 Akim Demaille <akim@epita.fr>
10430 * bin/autoscan.in (used): New.
10431 Use it.
10433 2001-11-26 Akim Demaille <akim@epita.fr>
10435 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10436 directives.
10437 (&scan_sh_file): Remove a duplicate pattern.
10438 (&check_configure_ac): Use long options.
10439 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10441 2001-11-26 Akim Demaille <akim@epita.fr>
10443 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10444 Before, having a line containing the opening of a multi line
10445 comment made the whole line be ignored.
10447 2001-11-26 Akim Demaille <akim@epita.fr>
10449 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10450 (testsuite Scripts): Be one of its subsection.
10451 (Autotest Logs): New.
10453 2001-11-26 Akim Demaille <akim@epita.fr>
10455 Test groups are now run two directories deeper.
10457 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10458 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10459 at_top_builddir.
10460 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10461 top_srcdir, builddir and top_builddir.
10462 Use `at_*dir' relatively to the directory containing the
10463 suite, use `*dir' when relatively to the current group dir.
10465 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10467 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10468 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10469 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10470 spelling errors.
10472 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10474 * doc/autoconf.texi (Using System Type): Add an example of `case
10475 $host' usage so people quit using `case $target' everywhere.
10477 2001-11-22 Akim Demaille <akim@epita.fr>
10479 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10480 spotted by Jim Meyering.
10482 2001-11-16 Paul Eggert <eggert@twinsun.com>
10484 This patch implements a `long double' suggestion by Oliver Kiddle.
10486 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10487 static, to catch errors if the value isn't known at compile-time
10488 and the compiler supports dynamic arrays. Change its name from
10489 `_array_' to `test_array' to avoid potential name clashes.
10490 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10491 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10492 better than double. Catch a bug in GCC 2.95.2 x86.
10493 * doc/autoconf.texi (C Compiler): Document the above.
10494 * NEWS: Likewise.
10496 2001-11-13 Akim Demaille <akim@epita.fr>
10498 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10499 hand.
10500 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10502 2001-11-13 Akim Demaille <akim@epita.fr>
10504 * lib/autotest/general.m4 (AT_INIT): After having run the test
10505 group, go back to the initial directory, not to at_suite_dir.
10507 2001-11-13 Akim Demaille <akim@epita.fr>
10509 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10510 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10511 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10512 option.
10513 (AT_CHECK_CONFIGURE): Use absolute paths.
10514 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10515 The problem is still the old one: there is no means in M4 (that I
10516 know about) to create a defining macro, because there is no means
10517 to create `$1' etc., therefore, the defining macro ``swallows''
10518 all the arguments meant to the defined macro.
10520 2001-11-13 Akim Demaille <akim@epita.fr>
10522 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10523 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10524 configure.ac.
10525 * tests/aclocal.m4: Remove, as it is no longer used.
10527 2001-11-13 Akim Demaille <akim@epita.fr>
10529 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10530 variable names when referring to a single test group, or to
10531 `suite' when referring to the whole test suite.
10532 `at_last_test' is removed: m4 compute at_format itself.
10533 (at_stdout, at_stder1, at_stderr): New variables.
10534 (AT_CHECK): Use them.
10536 2001-11-13 Akim Demaille <akim@epita.fr>
10538 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10539 in PATH.
10540 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10541 Do it as soon as a test fails, don't wait till the end of the test
10542 suite.
10543 Don't remove $as_me.[0-9]*, since these files no longer exist.
10545 2001-11-13 Akim Demaille <akim@epita.fr>
10547 * tests/tools.at: Use absolute paths, since we are no longer run
10548 in place.
10550 2001-11-13 Akim Demaille <akim@epita.fr>
10552 Now that tests are running in their own private dir, there is no
10553 need to list the files to remove at the end of tests groups.
10555 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10556 (AT_data_files, at_data_files): Remove.
10557 (AT_CLEANUP, AT_DATA): Simplify.
10558 (AT_INIT): Adjust.
10559 Remove the group dir if !debug && !failed.
10560 * tests/atspecific.m4: Adjust.
10562 2001-11-13 Akim Demaille <akim@epita.fr>
10564 Start a new layout for Autotest: `testsuite' creates
10565 `testsuite.dir' in which the at-check-line etc. files are to be
10566 found, and `testsuite.dir/003' where the test group 3 is run.
10568 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10569 at_check_line_file, at_format, at_test_normalized, at_group_dir
10570 are new variables.
10571 Create the directories.
10572 Use absolute paths for at- files.
10573 (AT_CHECK): Adjust.
10575 2001-11-11 Michael Matz <matz@kde.org>
10577 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10578 (m4_car2): New.
10579 (m4_car): Properly quote arguments.
10581 2001-11-13 Akim Demaille <akim@epita.fr>
10583 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10584 with stricter rules on LIBOBJS.
10586 2001-11-12 Paul Eggert <eggert@twinsun.com>
10588 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10589 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10590 __PROTOTYPES too.
10592 2001-11-12 Akim Demaille <akim@epita.fr>
10594 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10596 2001-11-12 Akim Demaille <akim@epita.fr>
10598 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10599 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10600 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10601 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10602 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10603 specify to what the macro should be defined (typically to 1).
10605 2001-11-12 Akim Demaille <akim@epita.fr>
10607 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10608 From Jim Meyering.
10610 2001-11-12 Akim Demaille <akim@epita.fr>
10612 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10613 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10614 definition used by Automake where LEX is +/- "${missing} lex" and
10615 `missing' itself contains variables.
10617 2001-11-12 Akim Demaille <akim@epita.fr>
10619 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10620 Now that M4sh pushes BODY, the comments were output at the end of
10621 the test suites.
10623 2001-11-08 Akim Demaille <akim@epita.fr>
10625 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10626 that we can trace macros from aclocal.m4.
10627 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10628 obsoleted, and redirect to the former anyway.
10629 Reported by Ralf Corsepius.
10631 2001-11-08 Akim Demaille <akim@epita.fr>
10633 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10634 processed only if present.
10635 * tests/torture.at (Configuring subdirectories): Use autoreconf
10636 instead of successive calls to autoconf.
10637 Add a nonexistent subdirectory to exercise the patch above.
10638 Reported by Ralf Corsepius.
10640 2001-11-08 Kevin Ryde <user42@zip.com.au>
10642 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10643 doesn't accept .S files.
10645 2001-11-07 Akim Demaille <akim@epita.fr>
10647 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10648 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10649 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10650 * bin/autom4te.in (warn_forbidden): New.
10651 (handle_output): Use it.
10652 Read m4_pattern_forbid with messages.
10654 2001-11-05 Akim Demaille <akim@epita.fr>
10656 * bin/autom4te.in (--normalize): Remove.
10657 * lib/autom4te.in: Adjust.
10659 2001-11-05 Akim Demaille <akim@epita.fr>
10661 * tests/Makefile.am (testsuite): Rename this target as...
10662 ($(TESTSUITE)): this.
10663 From Nicolas Joly.
10665 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10667 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10668 the --prefix option, also remove it's argument.
10670 2001-11-05 Akim Demaille <akim@epita.fr>
10672 * doc/autoconf.texi (testsuite Invocation): Update.

10681 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10682 (&file_name_is_absolute): New, wrappers around routines from
10683 File::Spec.
10684 Use and export them.
10685 (&find_configure_ac): Optionally take a directory where to look at.
10686 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10687 the arguments.
10688 Default @ARGV to `.', not find_configure_ac.

10697 Add basename, dirname, and fileparse.
10698 (@EXPORT): Adjust.
10699 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10700 Don't look for aclocal flags if we already know aclocal is not
10701 used.
10702 Move aclocal.m4t only if it exists.
10703 Reported by Ezra Peisach.
10705 2001-11-03 Akim Demaille <akim@epita.fr>
10707 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10708 passed on command line, defaulting to ./configure.ac if present.
10709 (&maybe_autoreconf, File::Find): Remove, unused.
10710 (&autoreconf): If autoconf is not used, don't try to trace.
10712 2001-11-02 Akim Demaille <akim@epita.fr>
10714 * configure.ac: Bump to 2.52g.
10716 2001-11-02 Akim Demaille <akim@epita.fr>
10718 Version 2.52f.
10720 2001-11-02 Akim Demaille <akim@epita.fr>
10722 * config/config.guess, config/config.sub, doc/standards.texi:
10723 * config/lispdir.m4: Update from masters.
10724 * configure.ac: Bump to 2.52f.
10726 2001-11-02 Akim Demaille <akim@epita.fr>

10729 Don't run aclocal when aclocal.m4 is not from aclocal.
10730 From Ezra Peisach.
10731 Don't run libtoolize and gettextize if --install is not given.
10733 2001-11-01 Paul Eggert <eggert@twinsun.com>
10735 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10736 be invoked before _AS_LINENO_PREPARE.
10737 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10738 than character ranges.
10740 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10741 invoking AS_BASENAME. Set the locale variables to 'C' if
10742 possible, as POSIX requires this to get the traditional
10743 behavior.
10744 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10746 2001-10-31 Paul Eggert <eggert@twinsun.com>
10748 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10749 with {}, as that triggers a bug in Bash 2.05.
10751 (_AS_LINENO_PREPARE): Use Sed rather than
10752 Awk. Fix the sed prepass to work even if there are multiple
10753 instances of $LINENO on the same line. Do not substitute for
10754 other variables like $LINENOT. Do not check file dates; such a
10755 check is unreliable on sufficiently fast machines, and removing
10756 the check makes the code simpler and more reliable. Check for
10757 output and chmod failures.
10759 * doc/autoconf.texi (Special Shell Variables): Document
10760 the above.
10762 2001-10-31 Akim Demaille <akim@epita.fr>
10764 * tests/Makefile.am (atconfig): Remove this target, Automake
10765 handles it now.
10767 2001-10-31 Akim Demaille <akim@epita.fr>
10769 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10770 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10771 provided, while it is optional.
10772 * configure.ac: Adjust.
10774 2001-10-26 Paul Eggert <eggert@twinsun.com>
10776 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10777 lib/Autom4te/Struct.pm:
10778 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10779 with 5.005_02.
10781 * doc/autoconf.texi (Special Shell Variables): Document some
10782 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10784 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10785 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10786 eval $LINENO is not portable in practice.
10788 2001-10-24 Akim Demaille <akim@epita.fr>
10790 * lib/Autom4te/General.pm (backname): New.
10792 2001-10-24 Akim Demaille <akim@epita.fr>
10794 * m4/: Remove, merged into...
10795 * config/: here.
10797 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10799 * doc/autoconf.texi (Shellology): Mention the problems with bash
10800 2.05's use of ANSI quoting in its `set' builtin.
10802 2001-10-22 Paul Eggert <eggert@twinsun.com>
10804 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10805 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10806 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10807 POSIX decided to standardize on the int flavor of strerror_r.
10808 Always do char* test, as there's no reason not to.
10809 Assign to a char* var, to catch strerror_r that returns int*.
10811 * doc/autoconf.texi (Particular Functions):
10812 Document the above changes. Also, document the fact that
10813 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10815 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10817 2001-10-20 Akim Demaille <akim@epita.fr>
10819 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10820 the executable was missing from the log.

10824 * lib/Autom4te/General.pm (&update_file): If destination is
10825 unchanged, remove the source.
10826 (&up_to_date_p): Don't be verbose, be debug.
10827 * bin/autoreconf.in: No longer support --m4dir.
10828 (&autoreconf): Display the full path of the configure.ac we are
10829 studying.
10830 Trace it only once.
10831 Be sure to honor --force with gettextize.
10832 Always run aclocal.
10833 * doc/autoconf.texi: Adjust.
10835 2001-10-20 Akim Demaille <akim@epita.fr>
10837 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10838 Remove, dead.
10839 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10840 `intl' is already present, as it refuses unless --force.
10841 (&parse_args): Use -I, --include instead of the old Autoconf
10842 options.
10843 ($localdir, $autoconf_dir): Remove.
10844 (@include): New.
10845 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10847 2001-10-19 Jens Petersen <petersen@redhat.com>

10855 file in @configure_input@.
10856 Don't mention `automatically' in addition to `generated'.
10857 * tests/torture.at (#define header templates): Adjust.
10859 2001-10-19 Akim Demaille <akim@epita.fr>
10861 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10862 comment, explain how to install automatic mode selection.
10863 From Russ Allbery.
10865 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10867 * bin/autoreconf.in (autoreconf): Display the path to the
10868 configure.ac being studied.
10870 2001-10-18 Paul Eggert <eggert@twinsun.com>
10872 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10873 long, to work around a bug in the HP C compiler version HP92453-01
10874 B.11.11.23709.GP.
10876 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10877 (AS_BASENAME_EXPR): New macro.
10878 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10879 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10880 and fall back on 'sed' only if the other two fail. This makes
10881 AS_BASENAME act more like AS_DIRNAME.
10882 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10883 contains white space.
10884 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10885 Use AS_DIRNAME, since I think it's now DOS-friendly.
10886 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10887 Allow "dirname //FOO" to return either / or //, as POSIX allows
10888 either behavior.
10890 2001-10-10 Akim Demaille <akim@epita.fr>
10892 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
10893 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
10894 From Eric Sharkey.
10896 2001-10-10 Akim Demaille <akim@epita.fr>
10898 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
10899 m4_define, since...

10938 bother with $force since...
10939 * lib/Autom4te/General.pm: does.
10941 2001-10-08 Akim Demaille <akim@epita.fr>
10943 * bin/autoreconf.in: Rewrite in Perl.
10944 * configure.ac: Adjust.

10995 Use `add-log-current-defun-function' for ChangeLog creation.

11016 * tests/base.at: Adjust the tests to use AS_INIT.
11017 * tests/tools.at (AT_DATA_FORBIDDEN): New.

11028 empty, and if we can find a shell that does support LINENO,
11029 then set CONFIG_SHELL to that shell and then re-execute
11030 ourselves with CONFIG_SHELL.
11032 2001-10-05 Paul Eggert <eggert@twinsun.com>
11034 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
11035 doesn't exist. Remove *.tmp, as a .tmp file is created during the
11036 build of $(TESTSUITE).
11038 2001-10-05 Akim Demaille <akim@epita.fr>
11040 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

11082 instead of exec'ing to preserve $0 and $@.
11084 2001-10-01 Akim Demaille <akim@epita.fr>
11086 * tests/testsuite (AT_INIT) <at_pass_list>: New.

11105 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
11106 Don't use nested parenthesization. This patch was originally
11107 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
11108 but somehow it didn't get incorporated then.
11109 * doc/autoconf.texi (Limitations of Usual Tools):
11110 Clarify remark about sed and nested parenthesization.
11112 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
11113 Report an error if the size cannot be determined even though
11114 the type exists.
11115 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11116 Check for `expr' arithmetic overflow, and for compilation failure,
11117 and invoke a new argument $4 if either is discovered.
11118 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
11119 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
11121 2001-09-28 Akim Demaille <akim@epita.fr>

11141 status when executing the ACTION-IF-FALSE.

11262 2001-09-22 Akim Demaille <akim@epita.fr>
11264 Rely on `$LINENO' when possible instead of `__oline__'.
11266 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
11267 `$LINENO' support replacement when not supported.
11268 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
11269 them explicitly to be sure they are not output before this section

11279 character (u: -> ue) in a code comment.
11280 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
11281 it works.
11283 2001-09-21 Akim Demaille <akim@epita.fr>

11290 * lib/autoconf/programs.m4: Use extensions listed in
11291 $ac_executable_extensions when looking for programs.

11295 * lib/autoconf/general.m4: Fix a small Englisho.

11303 PATH_SEPARATOR.
11304 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

11307 * lib/autotest/general.m4: Replace occurrences of ':' in

11310 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11312 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
11313 arguments. Fixed a typo.
11315 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11317 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
11318 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
11320 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11322 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
11323 * bin/autoupdate.in: Ditto.
11324 * bin/autoheader.in: Reworded a few comments.
11325 * bin/autoconf.in: Reworded help text for a few options.

11329 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11331 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
11332 already have $file). Set output files to binary mode (helps avoid
11333 CR issues on DOSish systems).
11335 2001-09-19 Akim Demaille <akim@epita.fr>
11337 * lib/autotest/general.m4: Englishoes.
11338 From Tim Van Holder and Alexey Mahotkin.
11340 2001-09-18 Paul Eggert <eggert@twinsun.com>
11342 * doc/autoconf.texi (Common Shell Constructs): New node,
11343 documenting AS_DIRNAME.
11344 (Limitations of Usual Tools): Refer to it when discussing dirname.
11345 Also, update discussion of POSIX standard to reflect latest draft.
11347 * lib/autoconf/c.m4:
11348 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11350 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11351 Do not pass a first argument with leading '-'
11352 to expr, by parenthesizing initial integers that might be negative.
11354 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11355 now merely checks whether it is an error to pass an argument
11356 to getpgrp.
11358 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11359 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11360 whether it is a (compile-time) error to pass an argument to
11361 getpgrp. This simpler test supports the revised documentation,
11362 and is all that AC_FUNC_GETPGRP's users really need.
11364 2001-09-18 Akim Demaille <akim@epita.fr>
11366 * doc/autoconf.texi (Limitations of Make) <$<>: New.
11368 2001-09-18 Akim Demaille <akim@epita.fr>

11376 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11377 correctly.
11378 Add test for AS_BASENAME.
11379 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11380 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11381 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11382 * tests/base.at: Fixed the expected responses. The old ones were
11383 one line out...
11384 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11385 the documentation claims it should (and how it behaved in 2.13).
11387 2001-09-18 Akim Demaille <akim@epita.fr>
11389 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11390 the AC_CONFIG_COMMANDS invocation.
11391 This also solves the name clash problems.
11392 Don't set the package's ID.
11393 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11394 No longer to be shipped.
11395 (version.in): Remove.
11396 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11397 * lib/autoconf/status.m4: Adjust.
11398 Use `m4_PACKAGE_STRING'.
11399 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11400 the only optional argument is the name of the test suite.
11401 Expect `package.m4' to define the package signature.
11402 * lib/autom4te.in (Autotest): Add `package.m4?'.
11403 * tests/Makefile.am (package.m4): New.
11404 * tests/suite.at: ifnames is a victim.
11406 2001-09-18 Akim Demaille <akim@epita.fr>
11408 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11409 AC_LIBSOURCE, AC_CONFIG_FILES.
11410 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11411 program version string doesn't match the package's.
11412 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11413 after `(cached)'.

11417 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11418 Allow expression to return any value that can fit into unsigned long
11419 (not int, as before). Check for output errors.
11421 2001-09-17 Bruno Haible <haible@ilog.fr>
11423 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11424 Always include <stdio.h> and <stdlib.h>. Evaluate
11425 the expression in an extra function before these includes. Call
11426 fprintf "%d" only after ensuring the argument is of type 'int'.
11427 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11429 2001-09-17 Paul Eggert <eggert@twinsun.com>
11431 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11432 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11433 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11434 when they don't exist.
11436 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11437 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11438 need it.
11440 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11441 version with the version used by fileutils 4.1, except use
11442 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11443 we don't need it.
11445 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11447 2001-09-13 Akim Demaille <akim@epita.fr>
11449 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11450 _first_.
11451 Reported by Gerrit P. Haase.

11455 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

11471 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
11472 Likewise.

11478 (AT_VICTIMS): Similar to AT_KEYWORDS.
11479 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.

11483 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
11485 2001-09-13 Akim Demaille <akim@epita.fr>
11487 * lib/autotest/general.m4 (AT_INIT): Create and remove
11488 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11489 test suites can cohabit.
11491 2001-09-13 Akim Demaille <akim@epita.fr>
11493 * tests/mktests.sh: Don't output banners for empty test files.
11495 2001-09-13 Akim Demaille <akim@epita.fr>

11543 2001-09-10 Akim Demaille <akim@epita.fr>
11545 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

11570 * tests/suite.at (AT_VICTIMS): Use it.
11571 * tests/tools.at (autoupdating AC_PREREQ): Don't depend upon
11572 at_version.
11574 2001-09-07 Akim Demaille <akim@epita.fr>
11576 Move toward possibly stand-alone test suites.
11578 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
11579 in addition, it introduces useless differences in logs.
11580 (AT_INIT): Let atconfig and atlocal be both optional.
11581 Adjust PATH computation.
11582 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
11584 2001-09-07 Akim Demaille <akim@epita.fr>
11586 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon
11587 m4sugar/version.m4.
11589 2001-09-05 Akim Demaille <akim@epita.fr>
11591 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'

11593 From Uwe Seimet.
11595 2001-09-05 Akim Demaille <akim@epita.fr>
11597 * bin/autom4te.in: --language is -l, not -s.
11599 2001-09-05 Akim Demaille <akim@epita.fr>
11601 Be ready to handle filenames as stupid as `dnl.at', for if even
11602 the maintainer is dumb enough to do that...
11604 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11605 excellence in M4 quotation: consider `__file__' is active.
11607 And BTW, when invoking m4, pass the --include in the right order:
11608 the wrong one.
11610 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
11611 4m.
11613 2001-09-05 Akim Demaille <akim@epita.fr>
11615 * lib/Autom4te/XFile.pm: New lib file.
11616 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
11617 * bin/autoheader.in: Use it.
11619 2001-09-05 Akim Demaille <akim@epita.fr>
11621 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
11622 defined.

11631 * doc/autoconf.texi (autoscan Invocation): Adjust.
11633 2001-09-05 Akim Demaille <akim@epita.fr>
11635 CVS GNU M4 doesn't like `undefine(undefined)'.
11637 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
11638 New, extracted from main.
11639 Use IO::File wherever possible.
11640 (input.m4): Be constant, use -I instead of hard coding $tmp.
11641 Therefore be a quoted heredoc.
11642 Don't invoke `_au_disable', since ac was not loaded, but just
11643 `unm4.m4'.
11645 2001-08-31 Akim Demaille <akim@epita.fr>
11647 Version 2.52d.
11649 2001-08-31 Akim Demaille <akim@epita.fr>
11651 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
11652 previous patch.
11653 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
11655 2001-08-31 Akim Demaille <akim@epita.fr>
11657 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
11658 serious problems handling heredocs in heredocs.
11659 Reported by Nicolas Joly.
11661 2001-08-31 Akim Demaille <akim@epita.fr>
11663 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
11664 (Making testsuite Scripts): Update.
11666 2001-08-31 Akim Demaille <akim@epita.fr>
11668 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11670 2001-08-31 Akim Demaille <akim@epita.fr>
11672 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11673 (testsuite Scripts): There is no such thing as `atconfig.in'.
11674 And actually one diagram is missing: test suite runtime.
11676 2001-08-31 Akim Demaille <akim@epita.fr>
11678 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11679 inverse order.
11681 2001-08-31 Akim Demaille <akim@epita.fr>
11683 * bin/autoupdate.in (@include): `installcheck' revealed the path
11684 to m4sugar was lacking!
11686 2001-08-31 Akim Demaille <akim@epita.fr>
11688 * man/Makefile.am (.x.1): We really have to pass
11689 autom4te_perllibdir.
11691 2001-08-31 Akim Demaille <akim@epita.fr>
11693 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11694 debug scripts, in particular passing explicitly listed tests to
11695 run is stupid.
11697 2001-08-31 Akim Demaille <akim@epita.fr>
11699 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11700 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11701 Use directly autom4te, not autoconf.
11702 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
11704 2001-08-31 Akim Demaille <akim@epita.fr>
11706 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
11707 * bin/autoheader.in (%symbol): Strip arguments of macros.

11713 2001-08-31 Akim Demaille <akim@epita.fr>
11715 * bin/autom4te.in (&parse_args): Die on unknown languages.
11716 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
11717 need for autoconf.
11718 Promote --include over --macrodir and other obsolete options.
11720 2001-08-31 Akim Demaille <akim@epita.fr>
11722 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
11723 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
11724 * bin/autom4te.in ($autoconf): Pass --force.
11725 `print $out' doesn't print `$_' but `$out'.
11726 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11727 (autoheader): Pass --force since the test suite goes too fast for
11728 the time stamps.
11729 Adjust to the new autoheader messages.
11731 2001-08-31 Akim Demaille <akim@epita.fr>
11733 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11734 Check the completeness of the #template.
11735 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
11736 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
11737 invocation.
11739 2001-08-31 Akim Demaille <akim@epita.fr>
11741 * lib/Autom4te/General.pm (&find_file, &update_file): New.
11742 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11743 Drop AC_MACRODIR dead for real.
11744 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11745 `autoheader: `config.hin' is created'.
11746 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11748 2001-08-31 Akim Demaille <akim@epita.fr>
11750 * bin/autoheader.in: Rewrite in Perl.
11751 * tests/autoheader: Adjust.
11753 2001-08-31 Akim Demaille <akim@epita.fr>
11755 * bin/autoconf.in (--include, -I): New option.
11756 Map --localdir, --autoconf-dir onto it.
11757 Forward autom4te's options instead of interpreting them.
11758 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11759 There is no such envvar since the inception of autom4te.cfg.
11760 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11761 * bin/autoupdate.in: Adjust, and perform more control.
11762 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11763 * tests/autoconf: Dittowise.
11765 2001-08-31 Akim Demaille <akim@epita.fr>
11767 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11768 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11769 optionally `FILE'.
11770 Use -e, not -f, since /dev/null for instance is OK.
11771 (&parse_args): Adjust.
11772 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11774 2001-08-31 Akim Demaille <akim@epita.fr>
11776 * configure.ac: Also find tested executables in bin.
11777 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11778 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11779 installed peer executables, only PATH is allowed to resolve it.
11780 Pass `autoconf_dir' via options, not via invisible envvars.
11781 * lib/Autom4te/General.pm (&find_peer): Remove.
11782 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11783 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11784 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11785 find the executables for it.
11786 * tests/Makefile.am: Major cleanup. Too lazy to document...
11787 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11788 We only need PERL.
11789 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11790 indeed related to running the test suite, while passing
11791 --autoconf-dir and others is related to running non installed
11792 Autoconf executables. So don't do that, leave it to...
11793 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11794 * tests/autoscan: New.
11795 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11796 refer to library files: rely on --language.
11798 2001-08-29 Akim Demaille <akim@epita.fr>
11800 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11801 s/--set/--language/.
11803 2001-08-29 Akim Demaille <akim@epita.fr>
11805 * doc/autoconf.texi: Strip the @nodes.
11806 Suggested by Paul Eggert.
11807 (Initializing configure): Typo.
11809 2001-08-29 Akim Demaille <akim@epita.fr>
11811 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11812 Suggested by Paul Eggert.
11814 2001-08-29 Akim Demaille <akim@epita.fr>
11816 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11817 download in a tmp dir.
11819 2001-08-29 Akim Demaille <akim@epita.fr>
11821 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11822 case insensitive OSes out there :(
11823 From Tim Van Holder.
11825 2001-08-29 Akim Demaille <akim@epita.fr>
11827 * lib/autom4te.in: New.
11828 * lib/Makefile.am (edit, autom4te.cfg): New.
11829 * bin/autom4te.in (BEGIN): Simplify.
11830 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
11831 (&load_configuration): New. Use it.
11832 (&parse_args): Support --mode, --set, and --melt.
11833 * bin/autoconf.in: Simplify and adjust.
11834 * tests/Makefile.am (AUTOMAKE): Use --set.
11835 * tests/atlocal.in: Adjust.
11836 * BUGS: distcheck and check are weak.
11838 2001-08-29 Akim Demaille <akim@epita.fr>
11840 * lib/autotest/general.m4: Use
11841 foo=`(command) 2>/dev/null`
11842 not
11843 foo=`command` 2>/dev/null
11844 (at-devnull): Rename as...
11845 (AT-devnull): this.
11846 (--clean): Remove AT-* files too.
11847 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11848 Reported by Nicolas Joly.
11850 2001-08-28 Akim Demaille <akim@epita.fr>
11852 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
11853 quotes inside single quotes.
11854 Reported by Nicolas Joly.
11856 2001-08-28 Kevin Ryde <user42@zip.com.au>
11858 * doc/autoconf.texi (Function Portability): Mention C right shifts.
11860 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
11862 * lib/autotest/general.m4: Reword some messages.
11863 (AT_INIT): Check for the `times' builtin before using it.
11864 Support test ranges as arguments to the testsuite.
11865 Have -e imply -d as the help text suggested.
11867 2001-08-27 Akim Demaille <akim@epita.fr>
11869 * Makefile.maint: Formatting changes.
11870 (do-po-update, po-update, cvs-update, update): New targets.
11871 (AMTAR): Remove.
11873 2001-08-27 Akim Demaille <akim@epita.fr>
11875 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

11878 <AUTOTEST_PATH>: May contain absolute dir names.
11880 2001-08-27 Akim Demaille <akim@epita.fr>
11882 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11883 Support `VAR=VAL' as arguments.
11884 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
11885 may be set via the command line.
11887 2001-08-27 Akim Demaille <akim@epita.fr>
11889 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
11890 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
11891 first the build dirs, then the src dirs.

11894 2001-08-27 Akim Demaille <akim@epita.fr>
11896 * lib/autotest/general.m4 (AT_INIT): Output the definition of

11903 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11904 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11905 readable.
11906 Adjust callers.
11907 * doc/autoconf.texi (Configuration Actions): Document the vars
11908 available in commands.
11909 Emphasize the risks of collisions in init-cmds.

11913 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
11914 (Initializing configure): this new node.
11916 2001-08-27 Akim Demaille <akim@epita.fr>

11929 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

11939 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
11940 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
11941 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11942 -> ac_dir).
11943 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11944 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11946 2001-08-27 Akim Demaille <akim@epita.fr>

11971 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
11972 (AMTAR): Help automake define it.
11973 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
11974 needed, 1.5 can have a macro and a target with the same name.
11975 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
11976 * m4/strip.m4: New.

11989 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.

11991 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11992 the name of the directory they're in, instead of the filename,
11993 since version.m4 is now in m4sugar, but m4_acversion must not be
11994 classified as an Autoconf macro.
11995 ($input_m4): Don't qualify the path to m4sugar.
11996 Rather, pass autoconf_dir to m4.
11997 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
11998 * tests/suite.at: Require 2.52c.
12000 2001-08-27 Akim Demaille <akim@epita.fr>

12012 of config.log on traps.
12013 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
12014 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
12015 for config.status'.
12016 Open the log as soon as possible.
12017 Use the same log introduction as configure's.

12082 * NEWS, README, README-alpha, TODO, tests/README: This package is
12083 `Autoconf', not `autoconf' (the executable).
12085 2001-08-20 Akim Demaille <akim@epita.fr>
12087 Info readers seem to need `Index' in the index node title :(
12089 * doc/autoconf.texi: Reverse the 2001-08-15 change which
12090 simplified index node names.
12092 2001-08-20 Akim Demaille <akim@epita.fr>

12134 2001-08-20 Akim Demaille <akim@epita.fr>
12136 Huh!?!?! There are still some user EOF tags used, which prevents
12137 their use in AC_CONFIG_COMMANDS for instance...
12139 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
12140 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
12141 `_CSEOF', or `_ATEOF', as appropriate.

12201 2001-08-17 Akim Demaille <akim@epita.fr>
12203 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
12204 `$0.log' as for projects where testsuite is in src, we'd have
12205 testsuite.log created in src.

12209 * bin/autom4te.in (&parse_args): Recognize --normalize.

12219 2001-08-17 Akim Demaille <akim@epita.fr>
12221 * doc/autoconf.texi: Work around Texinfo buglets.
12222 (Transformation Rules): One example is enough, users are expected
12223 to have their brains on. And BTW, use DESTDIR.
12224 (dvar): New macro. Use it.
12226 2001-08-17 Akim Demaille <akim@epita.fr>
12228 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.
12229 * lib/autotest/general.m4 (AT_INIT): Use the relative dir when
12230 looking for ChangeLogs.
12232 2001-08-17 Akim Demaille <akim@epita.fr>
12234 * bin/autom4te.in: --normalize is a new option.
12235 * bin/autoconf.in: Use it.
12237 2001-08-17 Akim Demaille <akim@epita.fr>
12239 * bin/Makefile.am, lib/Autom4te/Makefile.am, lib/autoconf/Makefile.am

12261 * doc/install.texi: Use @command.

12263 (Defining Variables): this.
12265 2001-08-15 Akim Demaille <akim@epita.fr>
12267 * doc/autoconf.texi (Function Portability): sprintf's return
12268 value.
12269 From Kevin Ryde.
12271 2001-08-15 Akim Demaille <akim@epita.fr>
12273 * Makefile.maint (CVS): New.
12274 (local-check): Run changelog-check. last.
12275 (alpha): Don't depend upon local-check, since...
12276 (cvs-dist): depends upon it.
12278 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
12280 * tests/Makefile.am: Use a clean-local rule to remove
12281 autom4te.cache (it's a directory, not a file.
12282 * Makefile.am: Ditto (but maintainer-clean-local).
12284 2001-08-15 Akim Demaille <akim@epita.fr>
12286 * bin/autom4te.in (@m4_warning): New.
12287 (&handle_m4): Use it.
12288 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12289 warnings are issued at each run.
12290 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12291 is in the src tree.
12293 2001-08-15 Akim Demaille <akim@epita.fr>
12295 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
12296 don't waste time running `autoupdate --version' works.
12297 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
12299 2001-08-13 Akim Demaille <akim@epita.fr>
12301 * doc/autoconf.texi (ma): Rename this index as...
12302 (ac): this.
12304 2001-08-13 Akim Demaille <akim@epita.fr>

12315 duration of the test suite.
12317 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
12319 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
12320 endianness for comparison instead of relying on AT_CHECK_ENV.

12324 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
12325 to the INSTALL file.
12327 2001-08-11 Paul Eggert <eggert@twinsun.com>

12352 * tests/mktests.sh: Update year in copyright notice.
12354 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
12356 * tests/semantics.at (AC_C_BIGENDIAN): New test.
12358 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12360 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12361 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12362 * doc/autoconf.texi (C Compiler Characteristics): Update
12363 documentation for AC_C_BIGENDIAN.
12365 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12367 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12368 magic values from an object file when cross-compiling.
12369 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12371 2001-08-10 Akim Demaille <akim@epita.fr>
12373 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12374 effects.
12375 Suggested by Russ Allbery.
12377 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12379 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12380 current $prefix to the sub-configures.
12382 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12384 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12385 extension (needed on BeOS). Reported by Guido van Rossum.
12387 2001-08-09 Akim Demaille <akim@epita.fr>
12389 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12391 2001-08-07 Akim Demaille <akim@epita.fr>
12393 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12394 removed.
12395 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12396 No need to remove the files before and after the each test, before
12397 each test and at the end of the suite is enough.
12398 Display only the children `times', not the shell's.
12399 If the test failed or was skipped, at-times is not available.
12401 2001-08-07 Akim Demaille <akim@epita.fr>
12403 Always produce testsuite.log, including when there are no
12404 failures. This helps getting information on skipped tests, and
12405 duration of the tests. Err, implement the latter btw.
12407 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12408 Dump information on the first run of each test.
12409 (AT_CLEANUP): Create `at-times' containing the duration of the
12410 test group.
12412 2001-08-07 Akim Demaille <akim@epita.fr>
12414 The use of `dumpstat' revealed that `len' was used although it
12415 should not. m4_text_wrap was using it, but in the Autoconf world
12416 where it is legal. Hence (i) test M4sh in its own world, not
12417 Autoconf's, and (ii), ahem, fix the bug :)
12419 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12420 does not like `' instead of [].
12421 (AT_INIT): Forbid `^_?AT_'.
12422 And don't output such tokens.
12423 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12424 `script.as', and `autom4te.cache'.
12425 Remove `empty' and `macro' which are no longer used.
12426 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12427 * tests/m4sugar.at: Use it.
12428 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12430 2001-08-07 Akim Demaille <akim@epita.fr>
12432 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12434 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12436 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12438 2001-08-04 Akim Demaille <akim@epita.fr>
12440 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12441 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12442 AC_TRY_LINK.
12443 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12444 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12445 (AC_F77_MAIN): Likewise.
12447 2001-08-04 Akim Demaille <akim@epita.fr>
12449 Don't rely on M4sugar outputting the patterns in files, since we
12450 might process the output _without_ running m4, hence without these
12451 files.
12453 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12454 * bin/autom4te.in (@Request::includes): Remove, unused.
12455 (@Request::source): Rename as...
12456 (@Request::input): this.
12457 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12458 (&handle_output): Fetch the patterns from the traces.
12459 `$forbidden' and `$allowed' are constant: use m//o.
12460 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12461 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12463 2001-08-04 Akim Demaille <akim@epita.fr>
12465 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12466 autoconf', i.e., in addition to caching traces, cache the output.
12468 * bin/autom4te.in (Request::cache): Rename as...
