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

172 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
173 AC_CHECK_TYPE, AC_CHECK_TYPES.
174 * doc/autoconf.texi (Generic types): C types must be type-names
175 (the C terminology), not type-ids (the C++ term). C++ types
176 must not be anonymous.
177 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
178 for C++; this drops support for anonymous struct and union types,
179 which were problematic anyway.

195 * doc/autoconf.texi (Generic Types): Document the restrictions
196 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
197 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
198 with objects too. Document the restrictions on its use.
199 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
200 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
201 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
202 works but the latter doesn't, then it's a valid type.
203 This lets people use function types and so forth.
204 For C++ there doesn't seem to be a simple solution, so leave it alone.
205 (AC_CHECK_SIZEOF): Allow argument to be a variable.
206 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
207 AC_CHECK_TYPE; that wasn't documented or necessary.
209 2007-04-11 Stepan Kasal <kasal@ucw.cz>
211 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

262 2007-03-17 Jim Meyering <jim@meyering.net>
264 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
265 (Limitations of Usual Tools): Also list \< and \>, and mention that
266 HP-UX's grep, like the one from Solaris, does not support that syntax.
268 2007-03-09 Stepan Kasal <kasal@ucw.cz>
270 * doc/autoconf.texi (Specifying Names): `--host' does not

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

425 discussion about the allow_superuser_privileges example,
426 and change it a bit to make things clearer.
427 (Optimization and Wraparound): Clarify whether the compiler
428 will generate an infinite loop for the example derived from
429 Autoconf's mktime test.
430 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
431 Also, clarify unsigned multiplication overflow.
433 2007-01-04 Eric Blake <ebb9@byu.net>
435 * bin/Makefile.am (RELEASE_YEAR): New macro.
436 (edit): Use it to supply correct copyright year to scripts.
437 * bin/autoconf.as (version): Use it.
438 * bin/autoheader.in ($version): Likewise.

445 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
447 * doc/autoconf.texi (Integer Overflow): Revised based on today's
448 feedback. The most important changes document what happens when
449 you convert an out-of-range value to a signed integer type, and
450 say that (sum < a) != (b < 0) reliably detects overflow when sum =
453 * doc/autoconf.texi (Integer Overflow): Greatly expand and
454 rewrite, taking notions from the recent discussion on the gcc and
455 autoconf mailing lists; please see
456 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
457 and follow the many links.

460 (Signed Integer Division): New sections.
462 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
464 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
465 preprocessor macro arguments in traced name.
466 * doc/autoconf.texi (Defining symbols): Document longstanding
467 support for AC_DEFINE-ing macros with arguments, and document
468 behavior when the same variable has multiple AC_DEFINEs.
469 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
470 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
471 macros directly, giving much shorter and simpler code.
473 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
475 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
476 space before "$ac_configure_args" to prevent a 'config.status
477 --recheck' failure if ac_configure_args doesn't contain a leading
478 space. This works around a problem with the XEmacs configure.ac,
479 which uses the (undocumented) ac_configure_args variable
480 inconsistently with Autoconf.
482 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
484 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
485 Include <limits.h>, and use its INT_MAX to rewrite the
486 j loop so that it does not overflow 'int'. Problem reported by
488 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
489 Play it safe by shifting left by 1 rather than multiplying by 2,
490 as GCC is less likely to optimize this away when the value
491 is signed (when it assumes overflow leads to undefined behavior).
492 Also, don't assume time_t uses two's complement.
494 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
496 * tests/torture.at (Substitute a 2000-byte string): Avoid using
497 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
498 dumps core on it. Report by Tim Rice.

516 (Configure Option Checking). Tighten up the wording a bit.
517 (External Software, Package Options): Cross-reference to Option
518 Checking, and use this to shorten our section.
519 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
520 "$x" to test "x$foo" != x.
521 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
522 Don't warn if $enable_option_checking is "no".
523 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
524 ac_unrecognized_opts to the empty string.
525 Don't echo the unrecognized opts, as this might mishandle
526 backslashes or leading -.
527 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
528 usage next to the other --disable-FEATURE options in the
531 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
533 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
534 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
535 Print warning for unrecognized --with and --enable options
536 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
537 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
538 Disable option checking when subdirs are configured.
539 (AC_OUTPUT): If warnings are enabled, print warning about
540 unrecognized --with and --enable options at the end of
541 the configure output (as well as at the beginning).
542 * doc/autoconf.texi (Option Checking): New node.
543 Document new option warning functionality.
545 2006-12-16 Eric Blake <ebb9@byu.net>
547 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
548 * NEWS: Start news for current version.
550 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
552 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
553 Define HAVE_GETMNTENT to 1, not to the empty string.
554 Problem originally reported by Jochen Friedrich in
555 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
557 This change prompted by a problem report by Andrey Simonenko in
558 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
559 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
560 object-like macros only, in the traditional portable character
562 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
563 Warn about attempts to define things that are not identifiers.
564 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
565 awful hack that AC_DEFINEd macro names containing parentheses.
567 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
569 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
570 too drastic, even if Texinfo in theory requires it for info mode.
572 (config.status Invocation): Renamed back from Recreating a
574 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
575 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
577 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
579 * NEWS: Version 2.61a.
581 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
582 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
584 * NEWS: Document changes with echo and printf, and the lack
585 of limits on the total size of multi-line values of substituted
586 variables, and the AC_FUNC_FSEEKO fix.
588 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
590 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
591 Writing configure.ac.
592 (Autoconf Input Layout): Renamed from configure.ac Layout.
593 (Recreating a Configuration): Renamed from config.status Invocation.
594 (Obsolete Recreation): Renamed from Obsolete config.status Use.
595 (acconfig Header): Renamed from acconfig.h.
596 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
597 (Writing Testsuites): Renamed from Writing testsuite.at.
598 (Autom4te Cache): Renamed from autom4te.cache.
600 * BUGS: Remove mention of VPATH problem, since it's now documented
601 not to be a bug in the Autoconf build procedure itself, but rather
602 a problem with the proprietary `make' programs.
604 * doc/autoconf.texi (Build Directories): Add a cross reference
607 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
608 * doc/standards.texi: Sync from gnulib.
610 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
611 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
612 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
613 generated automatically.
615 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
617 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
618 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
619 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
621 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
623 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
624 `CEOF$ac_eof' special marker, the awk script cannot contain a
625 line matching `^CEOF', so this is not needed any more.
626 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
627 special marker in the test.
629 2006-12-06 Stepan Kasal <kasal@ucw.cz>
631 * tests/tools.at (autom4te preselections): Use `find -newer';
632 remove one of the sleeps.
634 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
635 more readable, using ...
636 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
638 * doc/autoconf.texi (autoheader Invocation): Do not double-
639 quote the parameter of `AH_BOTTOM' in the example.
641 2006-12-05 Stepan Kasal <kasal@ucw.cz>
643 * doc/autoconf.texi (Configuration Headers): Remove the
644 example with multiple input files.
645 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
646 multiple input files.
648 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
650 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
651 creating the awk substitution script, handle one input line at a
652 time, so that the maximum length of a substituted (multi-line)
653 value is not limited by the size of the sed pattern space.
654 The trade-off is a slightly repetitive sed script.
655 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
656 can only have up to 7 characters, due to Solaris 10 /bin/sed.
657 * tests/torture.at (Substitute a 2000-byte string): Increase the
658 test with several long lines, they should not be caught by sed
661 * tests/tools.at (autom4te preselections): New test, to flag
662 entries missing from autom4te.cfg.
663 Report by David Byron <dbyron@hheld.com>.
665 * tests/torture.at (Substitute a 2000-byte string): Actually use
666 AC_PROG_AWK, so the last change works as intended.
667 (Substitute and define special characters): Likewise.
668 (Substitute a newline): Likewise.
670 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
671 instead of `awk' consistently.
672 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
673 * tests/torture.at (Torturing config.status): Test both the
674 result of AC_PROG_AWK and plain awk.
675 (Substitute a 2000-byte string): Likewise.
676 (Substitute and define special characters): Likewise.
677 (Substitute a newline): Likewise.
679 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
681 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
682 can be assigned to a function pointer. Problem reported by
683 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
684 part of a patch by Ralf Wildenhues in that same bug report.
686 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
688 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
689 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
691 2006-12-01 Eric Blake <ebb9@byu.net>
693 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
694 cross-compiling from cygwin to mingw.
695 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
696 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
697 to lib/autoconf/c.m4.
699 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
701 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
702 string for more reliable failure. Wrap the entire test that
703 causes the broken Solaris printf to dump core, in a subshell,
704 so the segmentation fault message is reliably suppressed.
705 Fix shell expansion errors by using /usr/ucb/echo always;
706 avoid an error on systems without it by another subshell.
707 Avoid m4 expansion of `$1'. Set the zeroth argument of the
708 subshell-$as_echo to `as_echo', for better error message.
710 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
712 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
713 `BASH_SOURCE' contain a newline, set them to empty, as they may
716 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
718 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
719 years and is too hard to maintain now. The last straw was
720 reported by Jerker Baeck in
721 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
722 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
723 * doc/autoconf.texi (Particular Functions): Move
724 AC_FUNC_SETVBUF_REVERSED from here...
725 (Obsolete Macros): ... to here. Say that it does nothing now.
726 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
727 Turn into (almost) a no-op.
729 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
731 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
732 These macros are obsolescent and new applications shouldn't need them.
733 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
734 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
735 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):

740 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
742 * doc/autoconf.texi (Setting Output Variables): Mention that
743 @VAR1@VAR2 has unspecified behavior. Problem reported by
745 * NEWS: Mention this.
747 * Makefile.am: Put only a single '#' into the copyright notice,
748 so that it's also present in the output file. Standardize wording
749 in makefile copyright notices to match GNU coding standards.
750 * bin/Makefile.am: Likewise.
751 * doc/Makefile.am: Likewise.

760 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
763 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
765 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
766 in the sed script that mangles the awk script: delete up to the
767 first exclamation mark only.
768 * tests/torture.at (Substitute and define special characters):
771 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
773 Rewrite config files generation: avoid quadratic growth in
774 the number of substituted variables by using awk instead of sed
775 for the bulk of the substitutions.
776 * NEWS: Mention this.
777 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
778 forbidden in the output (and thus input) file.
779 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
780 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
781 generate just one large awk script for substitutions,
782 eliminating much of the earlier complexity, while adding some
783 new complexity. Only expand the substitution templates at
784 configure time, for smaller configure script size. If
785 _AC_SUBST_FILES are used, test 'awk' for working getline support
786 at config.status time. If absent, interpolate through the
787 shell. The awk script was written with much help
788 from Paolo Bonzini and Paul Eggert.
789 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
790 (_AC_SED_FRAG_NUM): Likewise.
791 (_AC_SUBST_CMDS): Renamed from...
792 (_AC_SED_CMDS): ...this.
793 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
794 * tests/torture.at (Substitute a 2000-byte string): Also
795 substitute a line with 1000 words, and a variable with several
797 (Substitute and define special characters): Test awk special
798 characters, and put substitution input strings `@foo@' in the
799 output, to test that no recursion happens; test several other
800 combinations from Paolo Bonzini.
802 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
804 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
805 that replaced echo with AS_ECHO where this wasn't necessary.
806 Problem reportd by Ralf Wildenhues.
807 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
808 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
809 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
811 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
813 * lib/freeze.mk (GREP): Removed, no need to initialize this.
815 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
817 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
818 that traditional Awk lacks 3-arg "split". It has it.
819 Mention that FS must be a single character, and a few other
820 99-byte limits of traditional Awk.
821 Mention that if (i in a) doesn't work with traditional Awk.
823 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
825 * tests/autotest.at (BSx641-newline in command):
826 (BS-BS-newline in command, BSx640-newline in command):
827 (Newline-CODE-BS-newline in command):
828 (Single-quote-BS-newline in command):
829 (Single-quote-newline-BS-newline in command):
830 Use printf '%s\n' instead of echo, for portability to hosts
831 where echo interprets backslashes. This will break on hosts
832 that lack printf, but for now let's assume all such hosts
833 are dead (if not, we should get reports of test failures).
835 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
837 'echo' has some portability problems, when given a first argument
838 with a leading '-', or when given any argument containing '\'.
839 Avoid using 'echo' in these cases.
840 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
841 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
842 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
843 * lib/autotest/general.m4 (AT_INIT): Likewise.
844 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
845 argument might be unportable.

864 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
865 * bin/autoconf.as: Redo verbose flag implementation, as the old
866 scheme wouldn't work with AS_ECHO.
867 * lib/autotest/general.m4 (AT_INIT): Likewise.
868 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
869 Don't use ECHO_T, since ECHO_N is now reliable.
870 * lib/autotest/general.m4 (AT_INIT): Likewise.
871 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
872 rather than using a here-document to put the script into a file.
873 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
875 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
876 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
877 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
878 bug, but we might as well stop using ECHO_N and ECHO_C internally.
879 * lib/autotest/general.m4 (AT_SETUP): Likewise.
880 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
881 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
882 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
883 operand, as AS_ECHO requires. Avoid double file name expansion.
884 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
885 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
886 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
887 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
888 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
889 Double-quote strings that would otherwise contain M4 comments.
890 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
892 * configure.ac (AC_INIT): Bump to 2.61a.
895 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
899 * configure.ac (AC_INIT): Bump to 2.61.
902 * tests/autotest.at (Macro with backslash in a test title):
903 Comment out for now, as this tests neither fails nor passes
904 reliably. Problem reported by Ralf Wildenhues.
906 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
908 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
909 in previous change, which caused test failures.
911 2006-11-16 Stepan Kasal <kasal@ucw.cz>
913 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
914 code for --enable, --disable, --with, and --without to...

991 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
994 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
996 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
997 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
998 Imported from a similar patch to gnulib by Bruno Haible.

1024 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
1025 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
1026 argument. Extend to check titles printed by ./micro-suite and

1029 Single-quote in a test title,
1030 Double-quote in a test title): Don't expect failure anymore.
1031 (Backslash in a test title): Put a non-whitespace character after the
1032 backslash so that Bourne shells might actually see it as an escape
1034 (Brackets in a test title,
1035 Pound in a test title,
1036 Comma in a test title,
1037 Quoted Macro in a test title,

1041 Macro with double-quote in a test title,
1042 Macro with backslash in a test title): New tests expected to fail.
1043 * tests/torture.at (#define header templates): M4-quote this title in
1044 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
1045 The visible effect was a stray [] in the testsuite output.
1047 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1049 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
1050 `trap ... 0' inside a function, for AIX sh.
1052 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1054 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1055 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1056 5363) simply issues a warning when dividing by zero at compile
1057 time. Problem reported by Elias Pipping.
1059 2006-10-26 Eric Blake <ebb9@byu.net>
1062 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1063 show effect on macros that expand with commas.

1088 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
1090 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1091 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1092 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1093 reported by Nelson H. F. Beebe for Coreutils 6.4.
1095 * tests/tools.at (autoconf --trace: user macros): Remove test
1096 for tracing multiline macros, since m4 1.4.7a uses a different
1097 way to number lines. Problem reported by Ralf Wildenhues.

1127 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1128 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

1173 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1175 (Imported from Automake.)
1176 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1177 which incorrectly sets the mode of an existing destination
1178 directory. In some cases the unpatched install-sh could do the
1179 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1180 system. We hope this is rare in practice, but it's clearly worth
1181 fixing. Problem reported by Alex Unleashed in
1182 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1183 Also, don't bother to check for -m bugs unless we're using -m;
1184 suggested by Stepan Kasal.

1232 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1233 added to the template can get mangled.
1235 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1237 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1238 include the default headers, and redefine obstack_chunk_alloc
1239 and obstack_chunk_free. Fixes false failure with glibc.
1241 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1243 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

1258 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1260 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1261 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1262 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1263 Use a better substitute, by inspecting the output of "ls"
1264 rather than just using ":".
1265 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1266 rather than AS_EXECUTABLE_P, since we needn't worry about
1267 non-regular files here.
1269 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1270 due to configuration hassles with this. See Tonya Underwood's report

1283 initialization which is not inherited through the environment
1284 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

1294 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1295 comment about ac_cpp_err; it was incorrect, and anyway
1296 ac_cpp_err is being removed below.
1297 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1298 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1299 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1301 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1302 with werror_flag and conftest.err and so forth. This is more
1303 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1304 and anyway the user shouldn't normally want to see this gorp logged.
1305 Problem reported by Ralf Wildenhues.
1306 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1307 empty, not 'no', since the rest of the code uses 'test -z'.

1311 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1312 Use a single call to AC_DO_TOKENS rather than multiple, for
1314 (_AC_LINK_IFELSE): Test that resulting file is executable.
1315 Problem reported by mwoehlke in
1316 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1318 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1319 than creating a file to use with test -x; this is much faster.
1321 2006-10-02 Bruno Haible <bruno@clisp.org>
1323 * lib/autom4te.in (Automake-preselections): Add
1324 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1326 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1328 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

1333 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

1335 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1336 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1337 still doesn't let the program compile.
1338 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1341 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1342 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1343 include it, without including anything else.
1344 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1346 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

1351 `error.h', and include it, for a `error_at_line' prototype.
1352 Use a nonempty format string in the link test.
1353 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,

1360 can apply to constants too, and that it checks for macro defns.
1361 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

1363 values. Problem reported by Ralf Wildenhues.

1525 except the first two arguments are reversed.
1526 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.

1576 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1577 didn't work if some values were cached but not others. Test for
1578 broken lex libraries like native ia64-hp-hpux11.22; see
1579 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1580 work around the problem by preferring an empty LEXLIB to -lfl or
1581 -ll. Let the user set LEXLIB='' to indicate no library needed.

1708 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1709 -Wundef -Werror". Problem reported by David Fang in

1733 problems with arg script text that doesn't end in newline, and

1736 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1738 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

1770 less skeptical about "volatile", after discussion with
1771 Bruno Haible on bug-gnulib.
1772 (Limitations of Usual Tools): Warn about sed stripping
1773 leading white space from text. From Bruno Haible.

1811 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1812 more globally, since the 2006-06-30 patch didn't suffice. Problem
1813 reported by Keith Marshall. Also, don't bother with builddir2,
1814 since it shouldn't be needed any more.
1816 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1818 * doc/autoconf.texi (Generic compiler characteristics):
1819 Document AC_COMPUTE_INT. Fix wrong statements on Default

1835 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1837 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1838 Require that long long int be at least 64 bits wide. C99 requires
1839 this and enough programs depend on it so we should check for it.
1840 Bruno Haible reports in
1841 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1842 that long long int is 32 bits wide with some nonstandard compilers.

1850 Problem reported by Keith Marshall in
1851 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1853 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1855 * doc/autoconf.texi: Be more consistent about using @acronym with
1856 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1857 quite right (it talked about "OSF/Tru64", even though the
1858 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1859 and it even mentioned "OSF 4"!) and at this point there's little
1860 reason to talk about OSF any more, since it died in 1994.
1861 (Specific Compiler Characteristics): Simplify example of
1862 negative-size array.
1863 (File Descriptors): Reorder to make the text flow better.
1864 Remove joke about "appreciate the various levels"; I didn't get it.

1866 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1867 (File Descriptors, Limitations of Usual Tools):
1868 Tone down the advice against renaming or removing open files.
1869 (Limitations of Usual Tools): Add a new section, on 'rm'.
1871 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1873 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1874 -lXt in LIBS, idea from Karsten Hopp; this was due since
1877 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1878 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1879 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1880 (which belong to Xt, not X itself). See Debian bug 327655.
1882 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1884 * configure.ac (AC_INIT): Bump to 2.60a.

1904 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1906 * doc/autoconf.texi (Changed Directory Variables): New node,
1907 to document the whole `datarootdir' business a bit better.
1909 * tests/torture.at (datarootdir workaround): Extend test.

1914 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1915 when using default mode of IBM C 6 for AIX. Problem and two-line
1916 fix reported by Larry Jones.
1918 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1920 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1921 about literal '${datarootdir}' if a definition is found in the
1924 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1926 * NEWS: Use "M4" rather than "m4" when appropriate.
1927 Problem reported by Eric Blake.
1928 * doc/autoconf.texi: Likewise.
1929 Use @acronym around BSD, GCC, and GNU when appropriate.
1930 (Why GNU M4): Renamed from "Why GNU m4".
1931 (Redefined M4 Macros): Mention that Posix
1932 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1933 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1936 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1938 * bin/autom4te.in (handle_output): Do not forbid the empty
1940 * tests/tools.at (autoconf: the empty token): New test.
1942 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1944 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1945 calls, so that we do not care whether they are LIFO or FIFO;
1946 in the m4_wrap, do not check which diversion is the topmost
1947 one, just check that the stack is balanced at the end.
1948 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1949 base diversion forever--pop the previous diversion before
1950 opening the new one; consequently, remove the m4_wrap call.
1951 * lib/autotest/general.m4 (AT_INIT): Likewise.
1952 * tests/m4sugar.at: Do not use
1953 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1955 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1956 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1958 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1959 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1960 Rework example of m4wrap token-pasting trouble so that it doesn't
1961 care whether it's LIFO or FIFO.
1962 Fix some "contrary to"s that are awkward in English.
1964 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1966 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1967 to `yes' instead of `int$1_t' if the type is found, for more
1968 consistent configure output (where $1 is the number of bits).
1969 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1970 Suggested by Bruno Haible.
1972 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1973 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1974 with system headers. Report by Bruno Haible.
1976 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1978 * config/config.guess, config/config.sub: Sync from upstream.
1980 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1981 in order to avoid picking up an older installed frozen m4sh.m4f.
1982 Besides an outdated shell startup, this could have been created
1983 by an earlier M4 version with incompatible frozen file format.
1985 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1987 * README: Recommend m4 1.4.4 instead of 1.4.3..
1988 * doc/autoconf.texi: Likewise.
1989 (Special Chars in Names): Say that $(.FOO) is portable, as
1990 suggested by Stepan Kasal.
1991 (Installation Directory Variables, Build Directories):
1992 (Automatic Remaking, Subdirectories, Fortran Compiler):
1993 (Making testsuite Scripts, Defining Directories):
1994 Quote variable usages better.
1995 (Making testsuite Scripts): Add clean-local rule to makefile
1996 snippet, by Eric Blake.
1997 (Installation Directory Variables): Fix table item font.
1998 Reword slightly to clarify. Generalize advice about
1999 not using special characters to include all file-related
2000 vars, not just VPATH.
2001 (Special Chars in Variables): Warn about special characters in
2003 (Assignments): Clarify default-value example as suggested by
2005 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2006 (Special Shell Variables): Note leading ./ or ../, as suggested
2008 (Limitations of Builtins): Under cd, warn about CDPATH.
2009 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2012 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2014 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2015 `@var', for texi2html.
2016 (Systemology): Some more word wrapping, for DVI output.
2017 (autom4te Invocation): The short option for `--melt' is `-M',
2020 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2022 * doc/autoconf.texi: More formatting and English tweaks,
2023 many suggested by Ralf Wildenhues.
2024 Reword to avoid "@code{...}'s" and the like, since it's ugly
2025 with Emacs info mode. discontents -> woes.
2026 Put a few "will"s back. time stamp -> timestamp.
2027 side-effect -> side effect.
2029 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2031 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2032 Warn about $@ not persisting. Problem reported by Julien Danjou in
2033 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2034 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2035 Mention other special chars, too.
2037 2006-06-14 Eric Blake <ebb9@byu.net>
2039 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2041 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2043 * doc/autoconf.texi: Some systematic minor improvements, as
2044 follows. Use "makefile" when talking about makefiles
2045 generally (which might be named "makefile" or "Makefile" or even
2046 "foo.mk"), "Makefile" when talking about a specific makefile
2047 called "Makefile". This unclutters the text from weird quotes
2048 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2049 values" rather than "@var{foo}s" and similar constructs containing
2050 "}s". Use "Make rules" rather than "Makefile rules". Minor
2051 English-language improvements. Change the prefix "sub-" to "sub"
2053 Put blank lines around examples more consistently.
2054 Avoid "rather" and "very" as intensifiers.
2055 Avoid "will" as an auxiliary.
2056 (Limitations of Make): Split this node into....
2057 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2058 (Leading _ in Macro Names, Backslash-Newline-Newline):
2059 (Backslash-Newline Comments, Long Lines in Makefiles):
2060 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2061 (obj/ and Make, make -k Status, VPATH and Make):
2062 (VPATH and Double-colon, $< in Explicit Rules):
2063 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2064 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2065 New nodes, resulting from splitup of Limitations of Make.
2066 All cross-references changed. Raise the top node from
2067 a section to a chapter, and all subnodes accordingly.
2068 Redo the introductory wording to match the new organization.
2069 (Installation Directory Variables): Use an example that is
2070 closer to what Autoconf actually does. Mention that VPATH's
2071 value should not contain metacharacters or white space.
2072 (Fortran Compiler): Fix a VPATH bug in an example.
2073 (Leading _ in Macro Names): Mention that this problem is no longer
2074 of practical concern.
2075 (VPATH and Make): Reword the advice to make it clearer
2076 that Autoconf and Automake support VPATH in non-GNU make, but
2077 many packages have bugs in this area.
2078 ($< in Explicit Rules): Refer to Build Directories rather
2079 than using a (non-VPATH-safe) example.
2080 (Automatic Rule Rewriting): Mention the sort of disaster that
2081 can ensue with Solaris-style rule rewriting with VPATH.
2083 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2085 * doc/install.texi (Compilers and Options): Weaken the
2086 suggestion to use GNU make for VPATH builds.
2088 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2089 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2091 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2092 in regular expression.
2094 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2096 * doc/autoconf.texi (Installation Directory Variables):
2097 Drop extra @samp from `@table @samp' item.
2098 (Limitations of Usual Tools): Comment fix.
2099 Do not nest @samp just to point to other table items.
2100 (Writing testsuite.at) <AT_CHECK>: The second argument to
2101 `@dvar' is already @samp'ed.
2102 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2103 do not use @var in the second argument.
2105 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2107 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2108 $as_shell.exe too. Problem reported by Andreas Buening in
2109 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2111 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2113 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2114 `unused variable' compiler warning, for `-Wall -Werror'.
2115 Reported by Jaap Haitsma in
2116 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2118 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2120 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2121 case the compiler dumps core. Problem reported for
2122 OpenServer 5.0.7 by Tim Rice in
2123 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2124 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2127 2006-06-06 Tim Rice <tim@multitalents.net>.
2129 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2130 "ERROR" only shows up in "make check" output if there is an
2133 2006-06-06 Eric Blake <ebb9@byu.net>
2135 * tests/tools.at (automatically allowed tokens): Fix typo.
2137 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2139 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2141 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2142 typically overflows on x86 CPUs, even though the C standard
2145 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2147 * configure.ac (AC_INIT): Bump to 2.59e.
2150 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2154 * config/texinfo.tex: Sync from upstream.
2156 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2157 seen, invoke libtoolize with `--ltdl' argument.
2158 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2160 Suggested by Eric Blake.
2162 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2164 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2165 reported by Ralf Wildenhues.
2166 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
2168 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2172 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2174 * doc/autoconf.texi: Modernize some of the references to Solaris.
2176 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2178 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2179 message issued by AC_REQUIRE.
2180 * tests/m4sugar.at: Check m4_require's error message.
2181 * tests/base.at: Check AC_REQUIRE's error message.
2182 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2184 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2186 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2187 `expout' as the last parameter.
2188 * tests/tools.at: Adapt to the above change.
2190 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2192 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2193 information about race-free implementations of mkdir.

2197 * bin/autoreconf.in (help): Document M4 environment variable.
2198 * bin/autoconf.as (Usage): Likewise.
2199 * bin/autom4te.in (help): Likewise.
2200 * doc/autoconf.texi (autom4te Invocation): Likewise.
2202 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2204 * NEWS: GNU make now recommended for VPATH builds.
2205 Mention that some macros are now documented to be obsolescent.
2206 * doc/autoconf.texi:
2207 Prefer "current" to "modern" to describe
2208 currently-used (albeit perhaps old-fashioned) hosts.
2209 Mention which ancient features no longer need to be worried about.
2210 setgid -> set-group-ID
2211 setuid -> set-user-ID (these are the Posix terms)
2212 Fix some misuses of "only".
2213 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2214 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2215 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2216 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2217 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2218 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):

2220 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2221 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2222 Mention that these macros are obsolescent.
2223 (Installation Directory Variables): shall -> should
2224 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2225 Mention that it's now safe to use 3 and 4.
2226 (Limitations of Usual Tools): cp -r is now specified by Posix.
2227 Omit longwinded and obsolescent discussion of cp -f.
2228 Modernize discussion of expr, ls.
2229 (Limitations of Make): Modernize discussion of VPATH builds.
2230 Mention $? as a workaround in some cases.
2231 * doc/install.texi (Basic Installation):
2232 Mention "./configure; make; make install" first. Be more
2233 specific about why this file is generic. Remove unnecessary
2234 parens. Remove misleading "only". Remove obsolete advice
2235 about csh. Don't say "configure" takes awhile; say it
2236 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2237 and CC=c99 rather than CC=c89, as these are blessed by current
2238 Posix. Recommend GNU make if doing a VPATH build.
2240 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2242 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2243 examples involving shell prompts.
2245 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2246 and Paul Eggert <eggert@cs.ucla.edu>
2248 * doc/autoconf.texi (Here-Documents): Add details about the
2249 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2250 use "here-documents" instead of "here documents".
2252 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2254 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2256 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2258 * doc/autoconf.texi (File System Conventions): Warn about ":"
2259 anywhere in directory names.
2261 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2263 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2264 about quoting the case statement, just in case.
2265 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2266 was fixed in ksh93g; reported by Ralf Wildenhues.
2268 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2270 * doc/autoconf.texi (System Services): Do not document
2271 overriding EXEEXT via ac_cv_exeext=ext.
2272 (Particular Programs) <AC_PROG_MKDIR_P>:
2273 Document that ${MKDIR_P} understands --.

2277 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2279 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2280 argument with leading hyphen. Problem reported by Paul Eggert.
2282 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2284 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2285 about quoting ac_try: quote all of it, if any of it seems suspicious.
2286 This means we don't have to worry about ${ or sed any more.
2287 Also, double-quote the case statement, to work around misuses via
2288 underquoting as reported by Ralf Wildenhues in
2289 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2290 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2291 undocumented and dangerous macro.
2292 Problem reported by Ralf Wildenhues in
2293 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2295 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2297 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2298 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2299 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2301 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2303 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2304 since evidently some packages rely on the old, broken behavior.
2305 Problem reported by Ralf Wildenhues in
2306 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2307 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2308 pre-2006-05-26 definitions, but leave in the comments that
2309 these macros are dangerous and should not be used.
2310 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2311 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2312 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2313 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2314 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2316 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2318 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2319 the use of 'tr', since this is our only use of 'tr'.
2321 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2322 and Paul Eggert <eggert@cs.ucla.edu>
2324 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2325 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2327 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2329 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2330 the output file in the `${datarootdir}' test.
2332 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2333 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2335 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2336 mention of `datarootdir' in the input file(s), but literal
2337 `${datarootdir}' in the output file, and we haven't warned yet,
2338 then warn as well: the user may have (erroneously) used
2339 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2340 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2341 * tests/torture.at (datarootdir workaround): Extend this test.
2344 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2345 and Paul Eggert <eggert@cs.ucla.edu>
2347 * doc/autoconf.texi (autoheader Invocation): The first argument to
2348 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2349 alternatives and clear up the language a bit.
2351 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2353 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2354 ac_config_guess, ac_config_sub, ac_configure.
2355 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2356 Fix typo that prevented an unnecessary space from being removed.
2357 Problems reported by Ralf Wildenhues in:
2358 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2360 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2362 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2363 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2364 Don't use the term "thread-safe" to talk about mkdir race
2365 conditions, since the problem is more a process than a thread
2366 issue. Problem reported by Stepan Kasal in:
2367 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2368 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2369 the test for 'install' more closely. Look at MKDIR_P first.
2370 Look in the PATH, and at /opt/sfw/bin.
2371 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2372 Don't bother to try mkdir -p, since we already check mkdir --version;
2373 just look at the version number. (There's no easy way to check
2374 for race-free implementations.)
2375 * tests/tools.at (autoconf: subdirectories): Adjust to above
2376 changes, since MKDIR_P now might end in "/mkdir -p".
2378 * doc/autoconf.texi (autoheader Invocation): Mention that the
2379 first arg of AC_DEFINE_UNQUOTED must be a literal.
2380 Problem reported by Ben Pfaff in
2381 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2383 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2384 * doc/autoconf.texi (Special Chars in Variables): New section.
2385 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2386 (Installation Directory Variables): Quote $(datadir) better.
2387 (Limitations of Builtins): Describe some of eval's trickiness.
2389 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2390 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2391 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2392 in front of every arg, not just trailing args. Quote apostrophes.
2393 (_AC_EVAL_ECHO): New macro.
2394 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2395 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2397 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2398 exposed by quoting of eval argument. Put the command on line line
2400 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2401 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2402 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2403 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2404 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2405 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2406 Use eval more safely.
2407 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2408 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2410 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2411 lines, exposed by quoting of eval argument.
2413 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2414 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2416 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2417 initialization of `ac_cv_exeext', do not override it if it was
2418 already set, unless it was set to `no', for compatibility with
2419 Autoconf-2.13, and comment this.
2420 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2421 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2422 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2423 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2424 Document that this test may be overridden by setting
2427 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2429 Revert these two patches:
2431 2006-04-06 Eric Blake <ebb9@byu.net>
2432 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2433 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2436 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2437 Clean up _AC_COMPILER_EXEEXT* macros.
2438 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2439 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2440 ac_file to the name of the default output file and call
2441 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2442 initial `rm' of the candidate files...
2443 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2444 the same list in subsequent `rm' calls, and for the temporary
2445 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2446 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2447 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2448 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2449 no longer needed) by libtool. Make it a cache check.
2450 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2451 copied here by mistake.
2452 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2453 _AC_COMPILER_EXEEXT.
2454 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2455 _AC_COMPILER_OBJEXT directly.
2456 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2458 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2460 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2461 Fix description of how the buggy `sed' works.
2463 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2467 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2468 ENOLCK. Only mention `make -j' when applicable. Only raise
2469 fatal errors when `make -j' is involved. Improve error message.
2471 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2473 * doc/autoconf.texi (Here-Documents): We now know more about
2474 the variable expansion in here documents bug.
2475 Thanks to Tim Rice and Stepan Kasal.
2477 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2478 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2480 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2482 * tests/autotest.at (Multiline command from M4 expansion):
2483 No failure to be expected if the shell quotes newlines in
2484 commands in the `set -x' output. Report by Tim Rice.
2487 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2489 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2490 expansion in the here-documents used by config.status, as that
2491 runs afoul of the Korn shell version M-12/28/93d bug described in
2492 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2493 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2494 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2496 2006-05-23 Jim Meyering <jim@meyering.net>
2498 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2499 Fix typo introduced with 2006-04-02 change. It reversed the sense
2502 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2504 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2505 ac_dB slightly, to save bytes in the script.
2506 Max out at 50 lines, rather than 96; this is more likely
2507 (though not guaranteed) to avoid obscure 'sed' failures.
2509 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2511 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2512 `tr -d -' as bad option argument. Work around this by deleting
2513 an unrelated character.
2514 Report by Tim Rice <tim@multitalents.net>.
2516 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2517 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2518 Stepan Kasal <kasal@ucw.cz>
2520 * doc/autoconf.texi (Particular Programs): Do not promise that
2521 we always prefer the GNU version of the program, and that we
2522 search according to PATH; both rules can have exceptions.
2523 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2524 AC_PROG_SED. Move descriptions of limitations
2525 to the Limitations of Usual Tools section.
2526 (Limitations of Usual Tools) <sed>: Mention script length
2527 limitations with Solaris /usr/ucb/sed.
2528 <grep>: Fix wording for empty alternative. Mention that -c and
2529 -l should not be combined, and that -E and -F should not be
2532 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2533 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2535 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2536 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2538 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2540 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2541 AC_DEFINE is now passed to m4_pattern_allow.
2542 * NEWS: Mention that; likewise for AC_SUBST.
2543 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2544 the parameter to m4_pattern_allow.
2545 * tests/tools.at: Add a check for that.
2547 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2549 * lib/autoconf/status.m4: Fix typos.
2551 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2553 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2554 only the files that this macro generates.
2556 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2558 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2559 the HP-UX sed limitation of 99 commands, labels do not count.
2560 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2562 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2564 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2566 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2567 Import the following fix from coreutils:
2569 2006-01-13 Jim Meyering <jim@meyering.net>
2571 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2572 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2573 not double-quote uses of that variable, to accommodate the rare
2574 case in which getmntent is available in none of the libraries
2575 checked. This happens at least on FreeBSD 5.0.
2577 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2579 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2580 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2581 some other programs unwisely rely on these undocumented vars.
2582 But put in warning comments about them.
2583 Problem reported by Ralf Wildenhues in
2584 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2585 * NEWS: Document that these variables are intended to go away.
2587 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2589 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2590 and set the language to C++ (analogous to the equivalent Fortran
2593 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2594 * doc/autoconf.texi (C++ Compiler): Document it.
2595 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2598 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2600 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2601 that caused config.status to generate 100-command sed scripts; the
2602 portable limit is 99.
2604 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2606 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2607 variable `ac_d' instead of `d' to avoid infringing namespace.
2608 Report by Ralf Menzel.
2610 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2612 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2613 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2614 * tests/tools.at (autoconf: subdirectories): New test, taken from
2615 the corresponding problem report by Ralf Wildenhues in:
2616 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2618 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2619 Quote some uses of shell variables if they might suffer unexpected
2620 globbing. This doesn't fix all instances of quoting problems that
2621 I found, just the easy ones that look safe.
2622 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2623 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2624 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2625 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2626 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2627 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2628 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2630 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2631 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2633 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2635 * bin/autoreconf.in ($help): Reword according to the manual.
2636 Suggested by Olly Betts.
2638 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2639 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2641 * bin/autoreconf.in: Pass the directory argument to
2642 `require_configure_ac'. Fix comment.
2643 * tests/torture.at (Configuring subdirectories): Expose this.
2644 Reported by Olly Betts.
2646 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2648 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2649 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2650 Automake as follows:
2652 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2653 `$configure_in' instead of `configure.in', to preserve
2654 directory component.
2656 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2658 * config/config.guess, config/config.sub, config/texinfo.tex,
2659 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2661 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2663 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2664 test for C99 conformance; (bool) 0.5 is an integer constant
2665 expression, but (bool) -0.5 is not. Problem reported by Fedor
2666 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2668 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2670 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2671 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2672 Warn about obsolete install-sh files. Remove stray sentence
2673 fragment and fix cross reference.
2674 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2675 install -d; this undoes the 2006-05-10 change.
2676 (MKDIR_P): Mark with AN_MAKEVAR.
2677 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2678 that we don't require $INSTALL to be thread-safe. Move comments
2679 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2680 of AC_PROG_INSTALL. Output a message saying that we're checking
2681 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2682 MKDIR_P instead of AC_SUBST.
2683 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2684 Special magic for MKDIR_P, too.
2685 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2687 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2689 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2691 Sync from Automake, as follows:
2693 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2694 * config/install-sh: Initialize IFS, so field splitting isn't
2696 * config/mkinstalldirs: Likewise.
2697 * config/missing: Remove superfluous quotes. Replace all uses of
2698 `[' by `test', for consistency, and for..
2699 * config/missing (sed_minuso, sed_output): New variables.
2700 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2701 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2702 Fixes `missing' to detect `--output' for help2man. Fixes
2703 PR automake/483. Report by Dennis J. Linse.
2704 (autom4te): Document in `missing --help'.
2706 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2708 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2709 * config/install-sh: Don't use 'path' to talk about file names,
2710 as per GNU coding standards. Close a race condition reported by Ralf
2711 Wildenhues and Stepan Kasal. There is still a race condition
2712 on hosts that predate Posix 1003.1-1992, but we can't help this.
2713 Don't mishandle weird characters like space on pre-Posix hosts.
2714 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2715 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2716 AC_PROG_MKDIR_P from AS_MKDIR_P.
2717 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2718 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2719 earlier editions are not (including Automake 1.8.3).
2720 Do not suggest mkinstalldirs for thread-safety.
2721 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2722 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2723 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2724 presence of special characters and race conditions.
2725 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2726 in Autoconf's name space.
2728 2006-05-10 Bruno Haible <bruno@clisp.org>
2729 and Paul Eggert <eggert@cs.ucla.edu>
2731 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2732 from Automake with minor changes.
2733 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2735 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2737 * config/install-sh: Update to Automake CVS version, as follows:
2738 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2739 * lib/install-sh: Simplify the expr implementation of dirname.
2740 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2741 * lib/install-sh: Handle --, and diagnose unknown options.
2743 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2745 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2746 `./autom4te' to create `./testsuite', since the `all' target
2747 will ensure its presence, but `installcheck' should not create
2748 the uninstalled wrappers.
2750 * tests/torture.at (Unusual Automake input files): Skip if we
2751 detect automake < 1.8.
2753 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2755 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2756 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2757 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2760 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2762 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2763 munge (multiple) white space and other oddities.
2764 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2765 single quotes in variable assignment.
2766 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2767 and similar failures by adding multiple spaces, tabs, and other
2769 Report and different test suggested by Francesco Romani
2770 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2772 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2773 single quotes, we only need to search for single quotes; this
2774 both simplifies the search pattern, and makes us less
2775 susceptible to `echo' variations for arguments not containing
2777 (_AC_ARG_VAR_VALIDATE): Likewise.
2779 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2781 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2782 `$*' and IFS concatenation issue with traditional shells and
2783 bash-2.04. Report by Seanster@Seanster.com.
2785 2006-05-03 Bruno Haible <bruno@clisp.org>
2787 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2788 precisely which Mac OS X versions have the od problem.
2790 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2792 * doc/autoconf.texi: Use @option systematically.
2794 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2795 and Bruno Haible <bruno@clisp.org>
2797 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2799 (Integer Overflow): Mention the special case of integer division
2802 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2804 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2805 traditional shells like the Solaris one that do not use the
2806 first IFS character for assembling `$*'.

2861 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2863 * bin/autoconf.as (me): Replace by as_me.
2865 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2867 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2868 since as_me isn't set yet.
2870 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2872 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2873 a few minor bugs in this area.
2875 * doc/autoconf.texi (Programming in M4sh): Comment out the
2876 documentation of AS_BASENAME, for now.
2877 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2878 (Limitations of Builtins) <basename>: Do not refer to
2880 * bin/autoconf.as (me): Don't use AS_BASENAME.
2881 (dir): Remove the unused variable.
2882 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from

2896 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2898 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2899 of "run time" and "run-time" changed to "runtime", for consistency.

2901 * lib/autoconf/functions.m4: Likewise.
2902 * lib/autoconf/general.m4: Likewise.
2903 * lib/autoconf/headers.m4: Likewise.
2905 * doc/autoconf.texi (Run Time): Document the exit status situation
2906 with more accuracy and detail.
2908 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2910 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2911 Archive is not officially `GNU' any more. Update URL.
2912 (Defining Directories): Likewise
2913 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2915 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2917 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2918 newline from the `trap' code to finish `config.log'; the NetBSD
2919 /bin/sh resets the exit status after an empty command, as
2920 documented in doc/autoconf.texi.
2921 Reported by Dalibor Topic <robilad@kaffe.org>.
2923 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2925 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2926 Suggested by Bruno Haible.
2928 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2930 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2931 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2932 Instead, just list the shells that we know work.
2933 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2934 changed. Be more cautious about the _cv_ variable.
2935 * tests/tools.at (Syntax of the shell scripts): Check the
2936 _cv_ variable once, at first, to avoid an internal autoconf error
2937 when sh -n does not work.
2939 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2941 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2943 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2945 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2946 use ">&-" since we're only 99.999% sure that this is portable,
2947 and since the MinGW bug is fixed in a different way.
2948 * lib/autotest/general.m4 (AT_INIT): Likewise.
2950 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2952 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2953 before opening config.log, to avoid hitting a bug on MinGW.
2955 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2957 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2958 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2959 This works around a MinGW bug reported by Eric Paire.
2960 Make sure that all writes to the log file append to it,
2961 rather than possibly losing data.
2962 * lib/autotest/general.m4 (AT_INIT): Likewise.
2964 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2966 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2969 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2973 * configure.ac (AC_INIT): Bump to 2.59d.
2975 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2979 * Makefile.maint (news-date-check): Do not require a leading `*'
2980 before the release date in NEWS.
2982 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2983 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2985 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2986 the instantiated file do not contain the string 'datarootdir'
2987 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2988 @mandir@, replace the reference '${datarootdir}' by the value.
2989 * tests/torture.at (datarootdir workaround): New test.
2990 * NEWS: Advertise this temporary fixup.
2991 Based on a patch by Bruno Haible, reported and analyzed by
2992 Paul Eggert and Noah Misch.
2994 2006-04-12 Eric Blake <ebb9@byu.net>
2996 * tests/autotest.at (Debugging a failed test): Fix comment.
2998 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3000 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3001 all the changes since 2006-04-07.
3003 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3005 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3006 succeeded, but `ln -s file dir' failed, take care to remove the
3007 leftover target before the next test, to prevent its spurious
3008 failure; also make sure `ln file dir' works before selecting it.
3009 Thanks to Keith Marshall for pointing this out.
3012 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3013 assignments in `at_debug_args', so that we put them correctly
3014 in the `run' script.
3015 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3016 Reported by Eric Blake.
3018 2006-04-11 Eric Blake <ebb9@byu.net>
3020 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3021 top-level tests after micro-suite has been run. Used in...
3022 (Debugging a successful test, Debugging script and environment),
3023 (Debugging a failed test): ...these new tests. The first of these
3025 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3026 macro, split out from...
3027 (AT_INIT): ...here, so that using -d also generates a run script.
3028 Document that -d inhibits top-level logging.
3029 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3030 inhibits top-level logging; debug scripts are created.
3032 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3034 * tests/autotest.at (Empty test, Empty check): New test to check it.
3036 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3039 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3041 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3042 the files if a problem appears. Make the empty *.at files
3043 read-only, too. Proposed by Ralf Wildenhues.
3045 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3047 * config/Makefile.am: Add comment to force updated Makefile.in.
3049 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3050 space only patch to this file, this patch causes the Makefile.in
3051 files that include freeze.mk to be updated, and thus have a
3052 newer time stamp again, which in turn makes a pristine CVS
3053 checkout have correct time stamps.
3055 * Makefile.maint (cvs-sv): New macro, to be used..
3056 (config.guess-url_prefix, config.sub-url_prefix)
3057 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3058 point to CVS text checkout of Gnulib files.
3059 (copyright-check): Bump current year.
3060 (announcement): Do not hard-wire `./announce-gen'.
3061 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3063 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3065 (wget_files): Update config.guess, config.sub, texinfo.tex by
3066 `wget-update', now that their URLs work again.
3068 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3070 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3071 Problem noted by Paul D. Smith.
3073 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3075 * doc/autoconf.texi: Remove unused words from word list.
3076 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3077 .x-sc_trailing_space: New files.
3079 * doc/standards.texi: Sync from gnulib.
3081 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3082 `LIBOBJDIR' as experimental.
3084 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3085 with a target directory; it's internally implemented as `cp'
3086 anyway, but since Autoconf advertises the possibility to use
3087 a target directory when LN_S is `ln -s', we need to find out.
3088 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3089 analyzed by Keith Marshall <keith.marshall@total.com>.
3093 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3095 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3096 confdefs.h as-is. In general, if it has backslash-newline or the
3097 like, then it doesn't work either to sort or to remove empty
3100 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3102 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3104 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3106 * lib/autom4te.in (Automake-preselections): Preselect
3109 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3111 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3112 apostrophe within a single-quoted string, as this is the usual
3113 tradition and is easier to read than '"'"'. Don't rely on the
3114 shell treating "$/" like '$/'. Use a more-consistent indenting
3117 2006-04-09 Eric Blake <ebb9@byu.net>
3119 * tests/autotest.at (Backquote command substitution),
3120 (Multiline backquote command substitution): Remove mistaken
3121 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3123 (Parenthetical command substitution, Multiline parenthetical
3124 command substitution): here.
3126 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3128 Import macros from gnulib (often changing their name).

3158 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
3159 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3160 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3161 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3162 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3163 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3164 (Coding Style). Don't mention m4_expand_once.

3186 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
3188 2006-04-08 Stepan Kasal <kasal@ucw.cz>
3190 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
3191 of the warning introduced by the 2001-08-28 change.
3193 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
3194 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3196 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
3197 variables shall be overriden by the cache.

3201 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3203 Revert the patch from 2006-04-01 and only improve
3204 _AS_DETECT_BETTER_SHELL:
3206 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3207 skip nonexistent directories.
3208 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3209 only shell candidates which exist.
3210 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3211 * lib/autotest/general.m4 (AT_INIT): No need to give three
3212 parameters to _AS_PATH_WALK.
3214 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3215 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3217 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3218 distinguish m4sugar macros.
3219 * tests/tools.at (autoupdating with aclocal and m4_include):
3220 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3221 test case by Noah Misch <noah@cs.caltech.edu>.
3223 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3225 Revert my change from 2006-03-17, in other words:
3226 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3228 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3229 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3232 2006-04-07 Eric Blake <ebb9@byu.net>
3234 * doc/autoconf.texi (Programming in M4sh): Document that
3235 AS_MKDIR_P exits the script on failure.
3236 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3238 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3240 * config/elisp-comp, config/install-sh, config/mdate-sh,
3241 config/missing, config/mkinstalldirs: Sync from Automake.
3243 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync

3256 Paul Eggert <eggert@cs.ucla.edu>,
3257 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3259 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3260 whether `set' quotes correctly: redirect stderr of the tested
3261 `set', and use a subshell, for Ultrix; use `sed' instead of
3262 `grep' for zsh `set' which may write binary output; match only
3263 at the beginning of a line, to avoid false positives.
3264 In order to avoid false positives by unrelated variables with
3265 multiline content, put the dump algorithm in a subshell and
3266 unset all variables containing newlines (except some which are
3267 special to the shell). Warn about cache variables that are
3270 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3272 * config/config.guess, config/config.sub, config/texinfo.tex:

4221 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
4222 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4224 2005-10-25 Stepan Kasal <kasal@ucw.cz>
4226 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
4227 conftst2.$ac_objext.
4228 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4230 2005-10-24 Stepan Kasal <kasal@ucw.cz>
4232 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
4233 conftest.o, to see whether the compiler really obeys; rm the object
4234 file before and after the test and register it with ac_clean_files.
4235 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4237 2005-10-21 Stepan Kasal <kasal@ucw.cz>
4239 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
4240 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
4241 code so that the most common case requires less forks.
4243 2005-10-20 Stepan Kasal <kasal@ucw.cz>
4245 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
4246 not portable; thanks to Paul Eggert and Alexandre.
4248 * NEWS: Fix an old typo.
4250 2005-10-20 Jim Meyering <jim@meyering.net>
4252 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
4253 the latter'', in two places.
4255 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
4257 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
4258 AC_LANG_PROGRAM, fixing a typo. Don't give details about
4259 the inner workings of AC_LANG_FUNC_LINK_TRY.
4260 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
4261 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4262 by the function rather than ignoring it.
4263 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4264 comparing its address. Intel's interprocedural optimization was
4265 outsmarting the old heuristic. Problem reported by
4268 2005-10-19 Stepan Kasal <kasal@ucw.cz>
4270 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
4272 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
4274 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
4275 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
4277 2005-10-04 Stepan Kasal <kasal@ucw.cz>
4279 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
4280 before removing it (chmod -R u+rwx); there are three instances of this.
4282 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4283 Stepan Kasal <kasal@ucw.cz>
4285 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4286 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4287 make its content writable before removing it. Remove an errorneous
4288 comment from the end, where the logs of the failed tests are copied
4289 to the main log file.
4291 2005-09-27 Stepan Kasal <kasal@ucw.cz>
4293 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
4294 in case the computer is too quick. Double quote the configure.ac
4297 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
4298 problems if the testsuite were running too fast.
4300 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4302 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4303 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4304 (which belong to Xt, not X itself). See Debian bug 327655.
4305 * NEWS: Mention this.
4307 2005-09-07 Stepan Kasal <kasal@ucw.cz>
4309 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
4311 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
4313 * config/move-if-change: Don't output "$2 is unchanged";
4314 suggested by Ben Elliston. Handle weird characters correctly.
4316 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4318 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4319 calls, so that the final expansion of this macro is shorter.
4320 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4321 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4322 the cleanup there. Use AS_VAR_* macros, to be more general.
4323 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4325 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4327 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
4329 2005-09-01 Stepan Kasal <kasal@ucw.cz>
4331 * doc/autoconf.texi (Configuration Headers): Add an index entry
4334 2005-08-26 Pavel Roskin <proski@gnu.org>

4337 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
4340 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4342 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4343 The previous patch didn't work, so try a better one.
4345 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4347 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4348 in the example. Reported by Bruno Haible.
4349 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4350 "if $undefined_var;" succeeds with my shell.
4352 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4353 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4354 but change the m4_divert_text to m4_divert_once.
4356 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4358 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4359 Work around bug in Solaris /usr/xpg4/bin/awk.
4360 The bug is present in at least Solaris 8 through 10.
4362 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4364 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4365 some evil values and relying on the fact that $* concatenates the
4366 parameters by the first character from IFS.
4368 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4369 Stepan Kasal <kasal@ucw.cz>
4371 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4372 first header appears, define AH_HEADER.
4373 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4374 Update limitations about when to call AC_CONFIG_HEADERS.
4375 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4376 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4377 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4378 ``Configuration Actions''; fix their index entries.
4380 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4381 options correctly. Process N-M as M-N if M is smaller than N.
4382 Process ranges correctly so that N-N will run only N.
4383 Sort and uniquify the tests that will be run. If there is more
4384 than one test, reinsert the banners for the tests.
4385 * tests/autotest.at (Keywords): Unmark XFAIL.
4387 2005-08-23 Stepan Kasal <kasal@ucw.cz>
4389 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4390 before passing the macro name to AH_TEMPLATE.
4392 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4393 now opens log after option processing; in particular, --version
4394 and --help do not touch config.log.

4398 2005-08-22 Stepan Kasal <kasal@ucw.cz>

4406 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4407 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4410 * doc/autoconf.texi (Defining Symbols, Changed Results):
4411 Prepend to LIBS, not append, in examples.
4413 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4415 When building in place, set srcdir="."; suggested by Tim Van Holder.
4417 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4418 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4419 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4420 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4421 does not mean "no --srcdir option".
4423 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4425 * tests/autoscan.at (autoscan): New file.
4426 * tests/suite.at: Use it.

4430 * tests/autotest.at (Keywords): Test keywords combinations.
4432 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4434 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4435 add "2>&1"; gzip 1.2.4 prints help on stderr.
4437 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4439 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4440 was pushdef'ed twice while popped only once. Push it only once.
4441 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4443 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4445 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

4450 * Makefile.maint: Update from Bison.
4452 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4453 "<tab>" in comment, so that the point is understandable.
4455 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4457 Rewrite substantial part of lib/autoconf/status.m4.
4458 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4459 and CONFIG_COMMANDS are not processed in four separate loops.
4460 Instead, there is one main loop. This alows that the common code
4461 is expanded only once, thus config.status (and configure) is smaller.
4463 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4464 the AC_LIST_FILES and cousins macros are no longer used.
4466 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4467 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4468 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4469 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4470 contain the initialization, nor the for loop, nor the associated
4471 commands; all these go to ...
4472 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4473 _AC_OUTPUT_CONFIG_STATUS.
4474 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4475 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4476 (_AC_OUTPUT_FILE): The creation of the sed script ...
4477 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4478 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4479 _AC_OUTPUT_MAIN_LOOP.
4480 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4481 _AC_CONFIG_COMMANDS): Use ...
4482 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4483 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4484 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4485 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4486 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4487 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4489 (_AC_CONFIG_UNIQUE): Update.
4490 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4491 Replaced by this ...
4492 (_AC_LIST_TAGS): ... new common macro.
4493 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4494 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4495 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4496 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4497 this didn't belong to the `config commands' section.
4498 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4499 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4500 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4501 to the `config commands' section either.
4502 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4503 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4505 ... and many changes to the comments nearby.
4507 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4508 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4509 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4510 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4511 (#define header templates): The comment at the top of the generated
4512 header now includes the name(s) of the source file(s).
4514 Several unrelated small changes:
4516 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4517 parameter to AC_DIAGNOSE.
4518 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4519 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4520 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4521 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4523 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4524 in AC_OUTPUT doesn't double-quote it either.
4525 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4528 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4530 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4531 versions of Portland Group compiler produce single- and double-quoted
4532 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4533 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4535 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4537 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4538 This is a corrected version of yesterday's patch.
4540 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4542 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4543 path, too; insert a "===" to emphasize the line.
4545 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4546 ac_cv_build_alias to ac_build_alias.
4547 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4549 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4550 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4551 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4552 (AC_ARG_VAR): ... here.
4553 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4556 Keep a list of all precious variables and process them with one simple
4557 for loop, instead of expanding all commands, or, OTOH, complicated
4558 processing of output of "set".
4559 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4560 variable names in new macro...
4561 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4562 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4563 a loop to assign all ac_env_* and ac_cv_env_* variables.
4564 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4566 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4567 its value to shell variable ac_precious_vars and call
4568 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4569 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4570 _AC_ARG_VAR_VALIDATE.
4572 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4573 and the AC_SUBSTs ...

4577 the ac_subst_files section in config.log.

4591 They are generated by the Tru64 v5.1B shell.
4593 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4595 Fix my changes from 2005-07-01; reported by Noah Misch.
4596 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4597 description, the macro now accepts only a single tag.

4600 Fix cases when the varsions of Autoconf and Autotest don't match.
4601 Reported by Noah Misch.
4602 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4603 at_top_builddir, for compatibility with older autotest.
4604 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4605 is not set, use at_top_builddir, for compatibility with older
4606 versions of autoconf.
4608 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4610 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4611 Problem reported by Patrick Welche.
4613 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4615 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4616 sed substitution command, so that we allow | in program prefixes
4617 and program suffixes. (& is a problem anyway; we're not fixing
4619 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4620 configure_input, top_builddir, srcdir, etc.
4621 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4622 PATH_SEPARATOR in AUTOTEST_PATH.
4624 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4626 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4627 for loop over config.site files using `set', to allow
4628 directory names containing IFS characters.
4630 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4632 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4633 directories with weird names. Apparently some people like living
4634 on the edge. However, improve the test that "pwd" actually does
4635 report a name for the working directory.
4636 * NEWS: Remove the claim that we test for funny chars in dir names.
4638 2005-07-01 Stepan Kasal <kasal@ucw.cz>

4654 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4655 document to output the default config_* lists to config.status.
4656 Don't recognize option --file, if the functionality is not there.
4657 Likewise for --header; moreover, recognize --he and --h as shortcuts
4658 for --help in that case.
4660 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4661 matches the order of execution. No code changed.
4663 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4665 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

4683 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4684 (AC_SUBST): Call it.
4685 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4686 the directory specific variables; but don't call it for configure_input.
4688 2005-06-28 Derek Price <derek@ximbiot.com>
4690 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4693 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4695 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4696 directory have inherent problems with special characters like spaces,
4697 due to limitations in Make syntax. Problem reported by Alexandre
4699 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4712 from Justace Clutter.
4713 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4714 variable into diagnostic. Make the diagnostic an error, not a warning,
4715 because we really don't support spaces and suchlike in dir names.
4716 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4717 Don't worry about backslashes in srcdir; it can't happen now.

4728 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4730 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4731 that '\|' is not allowed in BREs; recommend using newline separated
4732 list of patterns instead of multiple -e options.
4734 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4736 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4744 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4745 b, t, r, w commands require single space, while : cannot have any.
4746 (Special Shell Variables): Fix sed code this in the example.
4747 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4748 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4750 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

4756 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4758 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4760 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4761 * doc/autoconf.texi:
4762 Don't mention Solaris versions so much, if a
4763 problem is common to all extant versions of Solaris. Say "SunOS
4764 4" instead of "SunOS" for SunOS 4.
4765 (awk): Mention more of the limitations of traditional Awk.
4766 (cat): Don't talk about cat -v.

4776 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4777 on Mac OS X 10.4 reported by Peter O'Gorman in:

4782 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4784 * doc/autoconf.texi: "filesystem" -> "file system".
4785 "behaviour" -> "behavior".
4786 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
4787 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4789 * lib/m4sugar/m4sh.m4: Likewise.
4790 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4791 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4793 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4794 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4795 to update the man page. That way, we don't have to check in new
4796 man pages every month.

4806 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4808 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4809 -u, since it outputs chatter if the input files are the same.
4810 Problem reported by Ralf Menzel.
4812 2005-06-08 Derek Price <derek@ximbiot.com>
4814 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4815 renaming them since they are about to be redefined anyhow.
4817 2005-06-08 Derek Price <derek@ximbiot.com>
4819 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4820 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4821 Move m4_undefine to alphabetical order.
4823 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4825 * README: Recommend GNU M4 1.4.3 or later.
4826 * doc/autoconf.texi (Introduction): Likewise.
4827 Reword to avoid some formatting glitches.
4828 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4829 Clarify explanation of HP compiler bug.
4830 Redo example output tp match current CVS snapshot.
4831 Use @example.org in email addresses when the examples
4832 might get inadvertently cut-and-pasted into user code.
4833 Remove example of autom4te usage that doesn't seem to work now.
4834 Use modern AC_INIT (except when the example is meant to be
4835 shown with Autoconf 2.13).
4836 Update ksh info for Solaris 9 and later.
4838 Modernize description of Automake versions a bit.
4839 Don't claim a future version of Autoconf is near.
4840 * doc/install.texi: Reword to avoid some formatting glitches.
4842 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4845 follows its own advice about quoting better.
4846 Reword to avoid some formatting glitches.
4847 * doc/installt.exi: Reword to avoid some formatting glitches.
4849 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4850 Tru64 ksh pattern matching bug. Reported against Libtool by
4851 Albert Chin <libtool@mlists.thewrittenword.com> and
4852 Nicolas Joly <njoly@pasteur.fr>.
4854 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4856 m4_cdr of one-member list was [[]] (one-member list containing an
4857 empty string) instead of [] (an empty list. Callers were skewed to
4858 match this misbehaviour. As a consequence of this:
4859 - m4_foreach([x], [], [foo]) expanded to `foo', while
4860 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4861 This bug has been fixed:
4863 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4864 expand to an empty string; print error msg if called without
4866 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4867 misbehaviour; handle [] and [[]] correctly.

4873 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4875 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4877 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4878 swallow records with more than 99 fields.
4879 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4880 parse the long line.
4882 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4884 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4885 swallow literals longer than 399. Reported by Ralf Wildenhues.
4886 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4887 to workaround this limitation.
4889 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4891 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4892 to gfortran, and make these the first two compiler names
4893 checked (following the general autoconf preference for gcc).
4895 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4897 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4898 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4899 (testsuite): Make sure autotest.m4f is up-to-date before using it.

4903 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4904 expression of unbounded size when processing the --list
4905 option. This runs afoul of a limit of 399 bytes per regular
4906 expression on AIX. Problem reported by Ralf Wildenhues.
4908 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

4911 * doc/autoconf.texi (Particular Headers): Reword example
4912 for multiline stdbool replacement.
4913 (Setting Output Variables): Reword text a bit. Don't
4914 give all the details about |#_!!_#|.
4915 Reword description of line replacement.
4917 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4919 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4920 now contain newlines, and substituted files must be referenced on
4921 a line alone; the sed scripts to substitute them are now very
4923 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4924 commands can be put in a sed script portably.
4925 * doc/autoconf.texi (Setting Output Variables): Document above
4926 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4927 use of multiline substitution.
4928 * tests/torture.at: No longer expect substitution of newline to fail.

4937 * tests/local.at: Don't attempt to check for negated character
4938 classes in shell scripts. The test was too brittle.
4940 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4942 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4943 * doc/autoconf.texi (Limitations of Builtins): Document this
4946 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4948 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4949 common code; used in many places in the tree.
4950 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4951 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4953 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.

4956 messages when ac_unique_file is not found.
4957 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4958 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4959 commands, for consistency with AC_MSG_ERROR and such.
4961 * bin/autoconf.as: Make more use of "shift 2" in option processing.

4974 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4975 (ac_top_builddir): ... this ...
4976 (ac_top_build_prefix): ... to this; the old name is also kept, for
4977 backward compatibility.
4978 (ac_top_builddir_sub): New variable, without the trailing slash,
4980 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

4994 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4995 argument to m4_foreach. I guess it was necessary in the past,
4996 but I think it's a no-op now.

5000 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5001 ``cat <<_ACEOF'' commands to one.

5217 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5218 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5219 ac_pwd, and quote srcdir.
5220 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5222 * doc/autoconf.texi: Fix some systematic formatting problems.
5223 ".)" needs a following @: if not at the end of a sentence, and
5224 similarly for "!)". "etc." should be preceded by a comma.
5225 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5227 2005-03-22 Bruno Haible <bruno@clisp.org>
5229 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's

5241 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5242 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5243 from a Common Lisp's `cl'.
5244 (AC_PROG_CXX): Behave according to the documentation: don't
5245 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5246 make the variable CCC precious; use `cl.exe', not `cl'.

5249 Alexandre Duret-Lutz <adl@gnu.org>
5251 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5252 /dev/null, as "configure" shouldn't read stdin, and this insulates
5253 us from problems (e.g., when testing for "cl"). Also, do this
5254 redirection before invoking "hostname" or "uname", and keep the
5255 original input stream available via...
5256 (AS_ORIGINAL_STDIN_FD): ... this new macro.

5269 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5270 newline if neither \c nor -n work, as that would output two
5271 newlines. Prefer -n to \c. Reported by Stepan Kasal.

5275 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.

5281 Undo previous change, except keep the change to
5282 lib/autoconf/programs.m4 that replaced grep with shell
5283 pattern-matching. This is because net-snmp configure reads stdin.

5288 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5289 from /dev/null, as "configure" shouldn't read stdin, and this
5290 insulates us from problems (e.g., when testing for "cl").
5291 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5292 before invoking "hostname" or "uname".
5293 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5294 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.

5296 "</dev/null" since it's now done at the top of 'configure'.
5297 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5298 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5299 Also, replace grep with shell pattern-matching, to save a process.

5303 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,

5404 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

5467 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5468 Update the long comment explaining it.
5470 m4_require no longer writes an ``is required by'' line to the
5471 execution stack. It contains only one bit of non-redundant
5472 information: that the macro was required, not called. And even
5473 this bit is useless in most situations: have you ever met a macro
5474 which both calls and requires the same macro?
5476 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5477 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5524 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5525 Warn about newline stripping in `` and $(). Update Solaris
5527 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5528 X insulates us from future changes to Posix.
5529 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

5577 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
5578 (_m4_divert_n_stack): New macro; the expansion is
5579 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
5581 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5582 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5583 stored in _m4_divert_diversion or _m4_divert_dump.
5584 (m4_divert_pop): When the parameter is given, compare the symbolic
5585 name with the last diversion pushed on the stack. Previously, the
5586 current diversion was compared with the numeric value of the
5587 diversion given as the parameter.
5588 (m4_require): If the macro hasn't been expanded yet, call ...
5589 (_m4_require_call): this new macro.

6078 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
6079 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
6080 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
6081 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
6083 More fixes to support spaces in the name of the build directory.
6084 This isn't a complete fix but it's an improvement.
6086 * bin/autoconf.as (autom4te_options): New var.
6087 Use it instead of appending to AUTOM4TE, so that we can allow
6088 spaces in the build directory's absolute name.
6089 * bin/autoheader.in ($autoconf): Allow spaces in file names.

6147 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6148 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6149 Don't fail if ENV or BASH_ENV is readonly.
6150 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,

6161 * doc/autoconf.texi (File System Conventions): Warn about
6162 names like "aux". Problem reported by Eric Blake.
6164 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6165 by zero instead of array size, so that we can use any arithmetic
6166 constant expression (instead of requiring an integer constant
6167 expression). This allows us to test expressions like DBL_MAX <
6168 LDBL_MAX, which didn't conform to the C standard using the old
6170 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6171 now that we can do floating-point tests at compile time.
6173 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6175 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6176 and LDBL_EPSILON, as the resulting expression isn't an
6177 integer constant expression and violates the C standard.
6178 Problem reported by Nelson H. F. Beebe. Also, check
6179 for "L" suffix, and check that long double doesn't have
6180 worse range or precision than double, that mixed-mode
6181 arithmetic doesn't generate a diagnostic, that double
6182 constants fit in long double.

6214 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6215 function F exists if the compiler and linker let you compile an
6216 expression like (F != 0). Recent versions of GCC optimize away
6217 the reference to F in that case, since every function address must
6218 be nonzero, so the link succeeds even if F does not exist.

6235 referencing AC_FUNC_STRERROR_R.

6238 note pessimistic assumption when cross compiling.
6240 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6242 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6243 (until 2004) invoked subcommands with sh -e, contra POSIX.
6244 Reported by Kevin Ryde.
6246 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6248 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6249 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6250 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6251 `test -f " /usr/bin/grep"', which _always_ failed.
6252 (AC_PROG_SED): Ditto bogus PATH fix.
6253 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6254 requires that grep correctly supports _multiple_ `-e' options, rather
6255 than stating only that grep should accept `-e'.
6257 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6259 Port to C99, which requires that 'exit' be declared.
6261 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6262 to ensure that stdlib.h is included.
6263 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6264 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6265 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6266 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6267 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6268 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6269 when using 'exit' in a test; C99 requires that 'exit' be declared.
6271 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6273 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6274 now prefers 'grep' implementations that accept -e.
6275 (Limitations of Usual Tools): Describe problems of traditional
6276 egrep and fgrep with long input lines, and of traditional grep
6278 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6279 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6280 All callers changed. Append /usr/xpg4/bin to the PATH, for
6282 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6283 the user with complaints about multiple -e options.
6284 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6285 Define it with AC_PROG_GREP.
6286 * configure.ac (AC_PROG_GREP): Add.
6287 * lib/freeze.mk (GREP): New macro.
6289 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6291 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6292 a possible candidate only after all others fail, rather than
6293 consulting it first. This improves backward compatibility by
6294 better reflecting the way shell selection occurred in previous
6295 versions of Autoconf, and should help to avoid triggering latent
6296 problems in other packages, such as the one in Automake where zsh
6297 is not handled robustly:
6298 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6299 Although it is not Autoconf's responsibility to work around
6300 problems in Automake, it nevertheless makes sense to avoid
6301 introducing unnecessary incompatibilites.
6303 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6304 Gary V. Vaughan <gary@gnu.org>
6306 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6307 how deeply nested we are when a suitable tool is found, set the
6308 ac_path_TOOL_found flag.
6309 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6310 nested we are in this macro. Break out of all 3 nested loops if
6311 ac_path_TOOL_found is set.
6313 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6315 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6316 of the _AS_PATH_WALK loop too if GNU flavor is found.
6318 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6320 * doc/autoconf.texi (Limitations of Make): Update documentation
6321 for `$<'. New entry `Long lines', based on a report from Simon
6322 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6323 paragraph about DJGPP, based on a mail from Richard Dawe.
6325 2004-04-20 Paul Eggert <eggert@twinsun.com>
6327 * tests/c.at (C keywords): Don't assume that GCC supports
6328 "restrict" and "inline", as sufficiently-old GCC versions do not
6329 (also, GCC configured to be in pedantic C89 mode does not).
6330 Problem reported by Sumit Pandya in:
6331 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6333 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6334 consider -g to work if it generates warnings when plain compiles
6335 don't. Problem reported by Braden McDaniel in:
6336 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6338 * doc/autoconf.texi (Slashes): New section, to document a problem
6339 reported by Jim Meyering in:
6340 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6342 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6343 linker output files before linking, to work around IRIX 6 linker bug.
6344 Problem reported by Rainer Orth in:
6345 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6347 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6349 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6350 best tool so far counter rely on the tool path variable name to
6351 avoid checks for one tool being affected by the results of running
6352 the length check on a previous tool.
6354 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6355 match expression argument, as different greps have different
6356 regular expression flavours.
6357 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6359 (AC_PROG_EGREP): Pass 'EGREP$'.
6360 (AC_PROG_GREP): Pass 'GREP$'.
6362 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6364 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6365 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6367 2004-03-29 Paul Eggert <eggert@twinsun.com>
6369 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6370 Types, Specific Compiler Characteristics, System Services,
6371 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6372 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6373 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6374 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6376 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

6385 2004-03-28 Paul Eggert <eggert@twinsun.com>
6387 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6388 now defines HAVE_DECL_TZNAME if it is declared, when
6389 HAVE_STRUCT_TM_TM_ZONE is not defined.
6390 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6391 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

6400 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6402 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6403 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6404 H. F. Beebe for the bug report.
6406 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6408 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6409 quoted -cmdline argument in Portland Group compiler (bug
6410 reported by Jeffrey J. Barteet).
6412 2004-03-25 Kevin Ryde <user42@zip.com.au>
6414 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to

6458 2004-03-03 Paul Eggert <eggert@twinsun.com>
6460 * bin/Makefile.am (edit): Don't use $< in a context where
6461 POSIX doesn't require support for it. Use $@.in instead.
6462 Problem reported by Anthony N. Frasso in
6463 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6464 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

6472 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6474 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
6475 is not always thread-safe. Report from Nathanael Nerode.
6477 2004-02-18 Paul Eggert <eggert@twinsun.com>
6479 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6480 problem on QNX reported by Stephen Rasku in

6492 AC_SUBST provides no portable way to escape literal newlines.
6494 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6495 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6496 Darwin uses -lcrt2.o and there's little point to cataloging all
6497 the system variants. Partial fix reported by Andreas Waechter in:

6573 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

6575 the 2003-05-22 change, which removed the older years from the list.
6576 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

6589 _AC_PROG_GREP, and AC_PROG_SED.

6622 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6623 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6624 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6625 not <inttypes.h>. Problem reported by Tim Mooney in
6626 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.

6630 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6631 otherwise "make check" fails because it forbids cmp (I guess

6635 have changed in 2004.

6647 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6648 -std1 disables some useful extensions on Tru64. Problem reported

6652 2004-01-14 Paul Eggert <eggert@twinsun.com>
6654 * doc/autoconf.texi (Programming in M4sh): Document that
6655 AS_MKDIR_P succeeds if the destination is a symbolic link
6656 to an existing directory.
6657 (Limitations of Usual Tools): Note that mkdir -p might not
6658 succeed on symlinks to directories.
6660 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6662 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

6674 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6676 2004-01-09 Paul Eggert <eggert@twinsun.com>
6678 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6679 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6680 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6681 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6682 AC_COMPILE_IFELSE, since we now assume our caller invokes
6683 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6684 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6685 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6686 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6688 2004-01-07 Paul Eggert <eggert@twinsun.com>
6690 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6691 `"'...'"`, as it's confusing (and I suspect it may not work on
6692 some platforms). The code was incorrect anyway, as it assumed
6693 that \$ evaluated to itself in that context. Reported by
6694 Alexandre Duret-Lutz.
6696 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6698 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

6748 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6749 -c -o might not work. From a suggestion by Kevin Ryde.
6750 (C Compiler, Generating Sources, Limitations
6751 of Usual Tools, Limitations of Make, Making testsuite Scripts):

6764 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6766 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6767 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

6769 explanation clearer.

7050 Problems reported by Eric Sunshine.
7052 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7054 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7055 -mGLOB_options_string stuff for Intel ifc, which can cause
7056 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
7057 pattern-matching instead of grep.

7077 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
7079 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7080 cache variable instead of $G77 to decide whether to include -O2,
7081 since $G77 is specific to Fortran 77.
7083 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7085 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
7086 free" flag. Re-order flags tested into rough order of popularity.
7088 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7090 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7091 arguments so that it can be used with syntax identical to
7092 AC_PROG_F77, and so that we can more easily decide to
7093 remove/deprecate the DIALECT optional argument in the future if it

7167 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7168 directory for AC_CONFIG_COMMANDS' first argument exists.

7194 The test suite are sometimes assigning timings incorrectly.
7195 Reported by Henk Krus.
7196 Diagnosed by Nicolas Joly.
7198 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7200 Instead of making AT_help a sequence of assignments to grow
7201 $at_help_all, just make AT_help_all be the growing contents of
7202 $at_help_all, and make a single assignment in...
7204 (at_times_skip): Flip the meaning and rename as...

7207 $at_times_file after use, and check it is present before trying to

7214 * bin/Makefile.am (edit): Handle '@configure_input@'.
7215 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
7216 (ifnames): chmod -w.
7217 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7218 executables, not bin/ executables! Otherwise all the magic needed
7219 to find non installed files is turned off. This caused a failure
7220 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7221 as found in its environment (sent by tests/autoreconf): pointing
7222 to bin/autom4te that could not find its files.
7223 * tests/mktests.sh: Force the replacement of generated files, for
7224 the sake of "mv" program that are interactive when overwriting a

7319 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7321 Add support for newer Fortran dialects. The F77 interface is
7322 unchanged, and continues to support Fortran 77. New FC macros
7323 correspond to all the old F77 macros, with output variables FC,
7324 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7325 available dialect, but older dialects can be specified. There are
7326 new macros AC_FC_SRCEXT to set the source extension, and
7327 AC_FC_FREEFORM to accept free-form source files.

7449 ($help): Use Autom4te::ChannelDefs::usage.

7453 2003-08-21 Akim Demaille <akim@epita.fr>
7455 First stab at preserving warnings between calls to autom4te,
7456 including when the cache is used.
7458 There are still several issues: (i) there are too many runs of m4
7459 (one for include, one for warnings, and some more), (ii) warnings
7460 spreading on several lines are not handled gracefully, (iii) the
7461 code meant to have the call stack display for errors does not work
7462 (its handling should move from m4 to autom4te).
7464 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7466 (@preselect): Add m4_warn.
7467 ($exit_status): Remove, use $exit_code.
7468 ($help): Use Autom4te::ChannelDefs::usage.
7469 (&handle_m4): No longer define the m4_warnings.
7470 At each run, extract and report the warnings.
7471 Always cache the result, including if the exit status is on
7472 failure, since if nothing changes, we should result in the same
7473 failure, hence we can use the cache.
7474 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7475 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7477 (m4_warn): Redefine as a do-nothing: it is its invocation that
7478 matters, as warnings are now reported via traces.
7479 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7480 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7481 the latter reveals calls to the former.
7485 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7487 2003-08-21 Akim Demaille <akim@epita.fr>

7519 * bin/autom4te: Adjust.
7520 In particular, be Autoconf tools are really silent when properly
7521 working, bind the verbosity of the 'note' channel to $verbose.

7585 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7586 shorter column three. Add DESCRIPTION to log file content.

7590 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

7612 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7613 -lcrt1.o, for OS X. (trivial change)
7615 2003-07-07 Paul Eggert <eggert@twinsun.com>
7617 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7618 inside '#ifndef __cplusplus'. Problem reported by
7621 2003-07-06 Bill Clarke <llib@computer.org>

7642 From Gareth McCaughan.
7644 2003-06-23 Akim Demaille <akim@epita.fr>
7646 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7647 not all of them. This fixes 1. the fact that when testing
7648 Autoconf there are many many config.log, 2. the incorrect use of
7649 top_srcdir to find config.log.
7650 Don't mix the detailed output of failed test with the summary of
7651 failures. Rather, append detailed log afterwards.
7653 2003-06-23 Akim Demaille <akim@epita.fr>
7655 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

7660 * tests/torture.at (#define header templates): Don't use quotes in

7729 is the inverse of localtime.

7738 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7740 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7741 Do not call `_exit()', simply modify `$?'.
7742 (xsystem): Reset $! before running system, and check it afterward.
7743 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7744 63 for version mismatches.
7746 2003-05-23 Akim Demaille <akim@epita.fr>
7748 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7749 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7750 the middle of a line).
7751 * lib/m4sugar/m4sugar.m4: Likewise.
7752 Remove useless spaces in comments.
7754 2003-05-23 Akim Demaille <akim@epita.fr>
7756 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7757 exit 63, so that we (or Automake's "missing") can tell the
7758 difference with a plain failure.

7768 Paul Eggert <eggert@twinsun.com>
7770 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7771 Remove `#include <stdlib.h>' from the list; we should never
7772 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7773 resulting namespace pollution would cause other tests to fail.
7774 Configure scripts run with some older versions of g++ and HP's
7775 aCC would fail due to such an #include. Problems reported by
7776 Matthew Mueller in <http://bugs.debian.org/120704> and by
7778 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7779 In the test, use the test declaration before including <stdlib.h>,
7780 as that's closer to how it'll be used.
7782 2003-05-23 Akim Demaille <akim@epita.fr>
7784 * doc/autoconf.texi (Header Portability): ucred.h.
7787 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7789 Overhaul Autotest's logging: generate separate log files
7790 in testsuite.dir/NNN/testsuite.log, and append them to
7791 testsuite.log instead of re-running the test verbosely.
7793 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7794 file descriptor, write 0 to at_status_file instead of setting
7795 at_status=0, initialize some new variables (at_status_file,
7796 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7797 to rerun the tests, instead append the at_group_log to the
7798 at_suite_log when a test fails.
7799 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7800 with the AS_MESSAGE_LOG_FD redirected to stdout.
7801 (AT_CLEANUP): save the output status in $at_status_file
7802 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7804 (AT_CHECK): since tests are run with a redirected stdout,
7805 and used to be re-run in verbose mode, turn some $at_verbose
7806 into echo, and don't redirect the output of testing stdout
7809 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7810 the name of the debugging directory and information about

7925 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
7927 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
7930 2003-05-06 Akim Demaille <akim@epita.fr>
7932 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7933 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7934 by aclocal.m4 is changed it might require the importing of another
7935 m4 extension file, i.e., aclocal must be run.
7937 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7938 (&parse_args): Use --force with aclocal if required and supported.
7939 (&autoreconf_current_directory): Use &run_aclocal.

7948 open during the whole autom4te run.
7949 ($icache_file): New.
7950 (&freeze): Lock the $icache_file.
7952 2003-04-29 Derek Price <derek@ximbiot.com>
7954 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7955 seperator with m4_append_uniq(). It doesn't work.
7956 (AT_CLEANUP): Add `;' to end of at_help_all.
7957 (AT_INIT): Allow --keywords to be specified more than once. When
7958 grepping $at_help_all for keywords, use the field and keyword
7959 seperators to ensure a complete keyword match. Alter at_prev handling
7960 to support the new --keywords behavior.
7962 2003-04-27 Karl Berry <karl@freefriends.org>
7964 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7965 align better with others. I also made some of the individual
7966 entries on one line, for brevity and to make it easier for me to
7967 sort my dir-example file in the Texinfo distribution :).

8054 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
8055 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
8056 use new diversions in preparation for accepting new arguments and
8057 allowing scripting around tests.
8058 (OPTIONS,TAIL): Remove these diversions to make way for the ones above.
8060 2003-03-26 Derek Price <derek@ximbiot.com>
8062 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of

8109 * doc/autoconf.texi (Limitations of Make): Remove the section
8110 about `$<' in inference rules, it was a bogus interpretation of
8111 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
8112 Tru64 make in the "target lookup" section.
8113 (Automake): Automake 1.5+ no longer requires special tools to be
8114 present on the developer's host.
8116 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
8118 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
8119 to a shell that can handle redirection or quoting correctly.
8120 Override SHELL with the shell detected by configure.
8121 Use of $^O suggested by Tim van Holder.
8122 * bin/autom4te.in (BEGIN): Likewise.
8123 * bin/autoreconf.in (BEGIN): Likewise.
8124 * bin/autoscan.in (BEGIN): Likewise.

8142 2003-02-25 Pavel Roskin <proski@gnu.org>
8144 * bin/autoheader.in: Add missing newline when printing

8149 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix typo in
8150 2002-09-01 patch by replacing "test -n" with "test -z".

8154 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
8155 to fix a mismatch between example and discussion.
8157 2003-02-24 Kevin Ryde <user42@zip.com.au>
8159 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8160 format starting with "-".
8162 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8164 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8165 is not portable inside Makefile.

8169 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8170 compiler says yeah, but preproc says nope, compiler is right.
8171 Conversely, prompt the reader to send a bug report to the
8172 maintainers of the package, not of Autoconf.
8174 2003-02-20 Klee Dienes <kdienes@apple.com>
8176 * bin/autoreconf.in (autoreconf_current_directory): Properly
8177 handle an empty aclocal.m4.

8181 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
8185 2002-12-23 Paul Eggert <eggert@twinsun.com>
8187 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8188 innocuous variant befor including <limits.h> or <assert.h>. This
8189 works around a bug reported by Albert Chin: HP-UX 11i
8190 (and earlier versions) have a <limits.h> that declares
8191 gettimeofday and many other functions.
8193 2002-12-03 Paul Eggert <eggert@twinsun.com>
8197 * NEWS, configure.ac: Update version.
8199 * doc/fdl.texi: Upgrade to FDL version 1.2.
8201 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8202 nontrivially in main's body, so that f's external declaration is
8203 not optimized away in AIX. This should fix the bug reported by
8205 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8207 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8208 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8209 defined, to support freestanding compilers. This should fix the
8210 bug reported by Momchil Velkov in
8211 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8213 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8214 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

8219 * Makefile.maint (www-gnu): New macro.
8220 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
8221 the location has moved.
8223 2002-12-02 Martin Frydl <martin@systinet.com>
8225 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
8226 \(.*\) match is too long and there is something more to be checked.
8227 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

8245 Update from masters.
8247 2002-11-14 Akim Demaille <akim@epita.fr>
8249 * Makefile.maint: Sync with Bison, i.e.:
8250 (po-check): Scan .l and .y files instead of the
8251 .c and the .h files that they generate. This fixes the bug
8252 reported by Tim Van Holder in:
8253 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8254 Look for N_ as well as for _. Try to avoid matching #define for
8258 2002-11-14 Akim Demaille <akim@epita.fr>
8260 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8261 From Paul Eggert and Albert Chin-A-Young.
8263 2002-11-14 Akim Demaille <akim@epita.fr>
8265 * doc/autoconf.texi (C Compiler): Solitary backslashes.
8266 From Paul Eggert and Albert Chin-A-Young.
8268 2002-11-14 Kevin Ryde <user42@zip.com.au>
8270 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8271 than assigning in main, to avoid HP cc +O3 optimizing it away.
8273 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8275 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8276 option. Process --recheck after parsing all options. Pass -q
8277 option to configure on --recheck.
8278 (AC_OUTPUT): Pass -q from configure to config.status.
8279 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8280 arguments to record.
8281 * doc/autoconf.texi (config.status Invocation): Document
8282 config.status -q option.
8284 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
8286 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore

8309 Reported by Ezra Peisach.
8311 2002-11-05 Akim Demaille <akim@epita.fr>
8313 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8315 We _have_ to stop using the old compatibility scheme that tried to
8316 avoid useless backslashes because Libtool 1.4.3 contains a
8317 AC_DEFINE([error_t], [int],
8318 [Define to a type to use for \`error_t' if it is not
8319 otherwise available.])
8320 We _have_ to quote the single quote and backslashes with \. The
8321 old compatibility scheme saw that ` was backslashed, and therefore
8322 did not quote the single quote. Hence before this patch, Autoconf
8323 was not compatible with Libtool.
8325 2002-11-04 Paul Eggert <eggert@twinsun.com>
8327 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8368 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8369 Make variable, not a shell variable.
8370 Suggested by Bruno Haible.
8372 2002-10-31 Akim Demaille <akim@epita.fr>

8407 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
8409 sparc_address_test returns void.
8410 Use it with an argument, as prototyped.
8413 2002-10-29 Akim Demaille <akim@epita.fr>

8777 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8778 aclocal invocation, as Gettext macros might not be visible to

9056 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9057 (ifnames, autoscan, autom4te): Since we don't only depend on
9058 configure.ac variables (such as VERSION etc.), but also on prefix
9059 and so forth, depend on Makefile, not configure.ac.
9060 Reported by Alexandre Duret-Lutz.
9061 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9063 2002-09-05 Kevin Ryde <user42@zip.com.au>
9065 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9066 doesn't seem to be confined to ia64, just say "some versions".
9068 2002-09-04 Akim Demaille <akim@epita.fr>
9070 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9072 * Makefile.am (maintainer-clean-local): Remove.
9073 (MAINTAINERCLEANFILES): Remove COPYING.
9075 2002-09-03 Paul Eggert <eggert@twinsun.com>
9077 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9078 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9081 2002-09-03 Akim Demaille <akim@epita.fr>
9083 * configure.ac: Bump to 2.53d.
9084 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9085 as of today, on Automake's team suggestion.
9087 2002-09-03 Akim Demaille <akim@epita.fr>
9091 2002-09-02 Akim Demaille <akim@epita.fr>
9093 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9095 * configure.ac: Disable SITE_MACRO_DIR.
9097 2002-09-02 Jim Meyering <meyering@lucent.com>
9099 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9100 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9101 Also, tweak grammar: s/make sure to/be sure to/.
9103 2002-09-02 Paul Eggert <eggert@twinsun.com>
9105 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9106 directory names are generally preferable to physical names.
9108 2002-09-02 Akim Demaille <akim@epita.fr>
9110 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9111 Reported by Raja R. Harinath.
9112 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9113 * bin/autoupdate.in: Use error instead of die.
9115 2002-09-01 Paul Eggert <eggert@twinsun.com>
9117 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9118 ordinary shell concatenation rather than echo+tr+sed command that
9119 runs afoul of a long-line-related sed bug in Solaris 8.
9121 * bin/autoheader.in (parse_args): --warning -> --warnings.
9123 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9124 stdout, as traditional "ls" does.
9125 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9126 _AC_COMPILER_EXEEXT_O): Likewise.
9127 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9129 * bin/autoconf.as: Add --prepend-include option. This patch was
9130 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9131 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9133 * bin/autoconf.in, configure: Regenerate.
9135 * doc/autoconf.texi (Special Shell Variables): Mention
9136 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9138 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9139 MAILPATH and set PS1, PS2, PS4 to default values, to work
9140 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9141 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9142 the Autoconf documentation specifies; fall back to "unset" only if
9143 this fails. Use a shell for-loop for this rather than an m4 loop,
9144 to shorten the output script.
9146 2002-08-30 Paul Eggert <eggert@twinsun.com>
9148 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9149 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9150 for the CDPATH problem. Document PWD.
9151 (Limitations of Builtins): Document the problem that "cd $foo" and
9152 "ls $foo" may refer to different directories in shells conforming
9153 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9154 example, since the old example is now out of date.
9156 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9157 FOO" and "ls FOO" talk about different directories; this catches
9158 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9161 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9162 of rolling our own unset.
9163 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9164 in practice we needn't worry about CDPATH if unset doesn't work.
9166 * Makefile.in, aclocal.m4, bin/Makefile.in,
9167 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9168 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9169 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9170 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9171 tests/Makefile.in: Regenerate with Automake 1.6.3.
9173 * config/config.guess, config/config.sub, config/mkinstalldirs:
9176 * configure: Regenerate with self.

9188 2002-08-29 Akim Demaille <akim@epita.fr>
9190 * lib/Autom4te/General.pm (&xqx): New.
9191 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9192 hand, which is not portable.
9194 * bin/autom4te.in: Use them.
9195 Use &error instead of die.
9196 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9199 2002-08-17 Paul Eggert <eggert@twinsun.com>
9201 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9202 default list of compilers to try, since it was long ago superseded
9203 by the ksh fc builtin. Suggested by Steven G. Johnson.
9205 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9207 * doc/autoconf.texi (Invoking autom4te): End the option table,
9208 fixing a bug introduced by the previous patch.
9209 (Limitations of Make): Add a 'target lookup' subentry in the
9210 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9212 2002-07-29 Mark D. Roth <roth@feep.net>
9214 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9215 options and use $AUTOM4TE_PATH.
9216 * doc/autoconf.texi: Remove documentation of autom4te
9217 --include-envvar and --site-macro-subdir options and document
9218 use of $AUTOM4TE_PATH.
9219 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9220 arguments from each language section.
9222 2002-07-29 Paul Eggert <eggert@twinsun.com>
9224 * doc/install.texi: Include copyright symbol in copyright notice.
9226 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9228 (AM_MAKEINFOFLAGS): New macro.
9229 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9230 * Makefile.am (INSTALL): Use the new macros.
9231 Use -o rather than --output, since "missing" does not grok --output.
9233 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9235 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9236 comments do not always work. Never trust the exit status of
9239 2002-07-24 Kevin Ryde <user42@zip.com.au>
9241 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9242 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9244 2002-07-23 Paul Eggert <eggert@twinsun.com>
9246 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9247 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9248 apparently treats PATH="nonexistent" as if it contained ".".
9249 Bug reported by Stefan `Sec' Zehl.
9251 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9253 * doc/autoconf.texi (Limitations of Make): Mention the special
9254 handling of the obj/ directory by BSD make.

9519 This improves on an earlier suggestion by H. Peter Anvin.
9521 2002-05-16 Paul Eggert <eggert@twinsun.com>
9523 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9524 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9525 Both macros now accept an optional source-dir arg.

9547 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9548 If prototypes are supported, use them to check this at compile-time,
9549 instead of trying to check it at run-time. If we must do a run-time
9550 check, assume that setvbuf is standard when cross-compiling, as
9551 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9552 Bug reported by Paul D. Smith.
9554 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9555 argument specifying location of getloadavg.c. This removes a
9556 FIXME. This idea was taken from Jim Meyering's implementation in
9558 * doc/autoconf.texi (Particular Functions): Document this.
9559 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9560 that's what the code does; this fixes a bug reported by
9563 2002-05-03 Akim Demaille <akim@epita.fr>
9565 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9566 autopoint instead of gettextize.
9567 ($uses_alocal): Rename as...
9568 ($uses_aclocal): this.
9569 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9570 Suggested by Bruno Haible.
9572 2002-05-03 Akim Demaille <akim@epita.fr>
9574 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9576 2002-04-29 Paul Eggert <eggert@twinsun.com>
9578 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9579 files to be 1 second older; just set them to be the same time.
9580 Also, sleep 1 second after the first aclocal, to work around
9581 problems with sub-second time stamps on the input files.
9583 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9585 * doc/autoconf.texi: Mention "set -e -x" lossage
9586 under node "Limitations of Builtins".

9592 From Christian Cornelssen.
9594 2002-04-29 Akim Demaille <akim@epita.fr>
9596 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9597 of lack of $LINENO support, then the test will compare the $LINENO
9598 in testsuite vs. the lineno in the test file. This is wrong, of
9600 Be sure to protect it.
9601 Reported by Patrick Welche.
9603 2002-04-25 Akim Demaille <akim@epita.fr>
9605 * doc/autoconf.texi (Obsolete Macros): Typo.
9606 Reported by Vladimir Volovich.
9608 2002-04-25 Akim Demaille <akim@epita.fr>
9610 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9611 than some of the input files, hence, on the second run of aclocal,
9612 if some of its input are younger, make them older.
9613 Suggested by Paul Eggert.
9615 2002-04-25 Akim Demaille <akim@epita.fr>
9617 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

9623 and ac_subst_vars be sh variables containing the list of
9624 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9626 (_AC_INIT_PREPARE): Use them to log them.
9627 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9628 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9629 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9630 _AC_SUBST_FILES and _AC_SUBST_VARS.
9631 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9633 2002-04-24 Akim Demaille <akim@epita.fr>
9635 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9636 autoheader, so that automake does not complain about a missing
9637 config.h.in that was to be created.
9639 2002-04-23 Akim Demaille <akim@epita.fr>
9641 * bin/autoheader.in (parse_args): --warning takes an argument.
9644 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9646 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

9691 Minor spelling and grammar fixes.
9693 * doc/autoconf.texi: Follow the outline suggested in the GNU
9694 Sample Texts sections of the Texinfo 4.2 manual. Most
9695 importantly, this makes sure that the copyright notices appear in
9696 all output formats. You probably need Texinfo 4.2 to generate

9723 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9725 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9726 from aclocal.m4 too.
9728 2002-04-12 Akim Demaille <akim@epita.fr>
9730 * tests/wrappl.as: New, M4sh precursor of wrappl.in.

9734 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9735 workaround for ${1+"$@"}.
9736 * doc/autoconf.texi (Shell Substitutions): Explain it.
9737 From Oliver Kiddle and Peter Stephenson.
9739 Have M4sh perform minimal shell sanitizing.
9741 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9743 (_AS_PREPARE): this new macro.
9745 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9746 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9748 Adjust Autoconf and Autotest.
9750 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9751 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9752 * lib/autotest/general.m4 (AT_INIT): Likewise.
9753 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9754 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9757 Use this M4sh to generate Autoconf's shell scripts.
9759 * tests/wrapsh.as: New, precursor of wrapsh.in.
9760 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9761 on Autotest and M4sh.
9762 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9763 (wrapsh.in): New target.
9764 * bin/autoconf.as: New, precursor of autoconf.in.
9765 (autoconf.in): New target.

9784 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9785 directories when descending in a SUBDIRS.
9786 Reported by Ezra Peisach.
9788 2002-04-04 Andreas Schwab <schwab@suse.de>
9790 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9791 contains no literal separators.
9793 2002-04-03 Akim Demaille <akim@epita.fr>
9795 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)

9797 Use dnl, not the KILL diversion.
9799 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9800 (AC_CONFIG_LINKS): here.
9802 Don't use the KILL diversion, as it kills spurious output, which
9803 results in failures being hidden.
9804 Use m4_defn where appropriate.
9805 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9806 after the second argument.
9808 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9809 syntax, as it is provided by M4sugar.

9829 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9831 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

9834 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9835 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9836 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.

9851 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9852 to avoid versions of HP C which don't allow that.
9854 2002-03-27 Paul Eggert <eggert@twinsun.com>
9856 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9857 (AS_SHELL_SANITIZE): Invoke it.
9858 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9860 2002-03-26 Akim Demaille <akim@epita.fr>
9862 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.

9874 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

9877 about VPATH, overriding of macros in sub-makes, and handling of
9880 2002-03-21 Paul Eggert <eggert@twinsun.com>
9882 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9883 problem with here-document buffer boundaries.
9885 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9886 when reinvoking the shell, to work around problems with installers
9887 who put strange things like "cd" commands in their environments.
9889 2002-03-19 Akim Demaille <akim@epita.fr>

9912 (Limitations of Usual Tools): Add mkdir section.
9914 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9915 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9916 back on AS_DIRNAME to compute prefixes otherwise; this is
9917 roughly what mkinstalldirs does. That way, we need not have
9918 our own filename disassembler. The old disassembler did not
9919 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9921 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9922 Create at_test_all by a series of assignments,
9923 not by a single assignment of a long string. The latter causes ksh
9924 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9925 presumably because of a buffer overrun.
9927 2002-03-14 Paul Eggert <eggert@twinsun.com>
9929 * lib/autotest/general.m4 (at_times_skip):
9930 Renamed from at_times. Now a boolean.
9931 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9932 says 'times: not found'.

9964 does not do it if --with-lispdir is given.

9982 aliases the actual variables, and modifications of the former
9985 2002-03-08 Akim Demaille <akim@epita.fr>
9987 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9988 because of C-c: have m4 output in tmp files, then mv them.
9990 2002-03-08 Akim Demaille <akim@epita.fr>
9992 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

10013 message for LIBOBJ.

10022 * doc/autoconf.texi (Transforming Names): Equality between target
10023 and host is irrelevant.
10024 (Specifying Names, Canonicalizing): Remove all references to the
10025 backward compatibility hooks. Rather, collect them all into...
10026 (Hosts and Cross-Compilation): this new section.
10027 * doc/install.texi (System Type): Ditto.
10028 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
10029 that `--host' implies cross-compilation.
10031 2002-03-04 Akim Demaille <akim@epita.fr>
10033 * doc/autoconf.texi (Evaluation Macros): New.
10034 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10036 (_m4_foreach): Define the variant with immediate evaluation so
10037 that it contains exactly the items, not an expression which
10038 evaluation is the current item.
10039 (m4_re_string, m4_re_word): Don't over quote them.
10041 2002-03-04 Akim Demaille <akim@epita.fr>
10043 Instead of having stacking `shift's evaluated at the end, let
10044 `foreach' loops immediately evaluate them.
10046 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10047 $*. This is the n-th time I change my mind, but hopefully this is
10050 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10052 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10053 it was only a hack for m4_text_wrap.
10054 (m4_car2): Remove, replaced by...
10056 (_m4_foreach): Adjust.
10057 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10058 m4_bpatsubst for clarification.

10110 AC_PREFIX_PROGRAM fails with dashed program names
10112 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

10218 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10219 AUTOTEST_PATH *after* it was set.
10220 Don't put `.' in the PATH: the user should be precise and `./' if
10221 needed. In addition, given that the test suite does some `cd', if
10222 `.' is in the path, the `tested programs' sections will report
10223 programs found in the test suite's directory, while during the
10224 tests (performed in their own directory), these programs are no
10225 longer visible. In other words, the results is confusing and

10274 Autoconf::General::getopt with non valid options.

10278 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

10296 * tests/Makefile.am (package.m4): New.
10297 EXTRA_DIST it since its a source.
10299 2002-01-06 Akim Demaille <akim@epita.fr>
10301 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10302 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10303 and PACKAGE_BUGREPORT from here...
10304 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10306 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10307 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10308 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
10309 * tests/tools.at (autoheader): Adjust.

10331 2001-12-14 Akim Demaille <akim@epita.fr>
10333 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10334 trailing files, don't apply `-rf' to files which might not be
10335 created by configure (core, core.*, and *.core), but just `rm -f'.
10336 Suggested by Jonathan Kamens.
10338 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

10362 2001-12-12 Kevin Ryde <user42@zip.com.au>
10364 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10365 forbidden file descriptors table.
10367 2001-11-26 Akim Demaille <akim@epita.fr>

10374 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10375 Remove $filepath, useless.
10376 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10377 variables, they are really part of the tokens.
10378 Split the input line on spaces and then look for tokens.
10379 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10380 because of `lex$U.$(OBJEXT)'.
10381 (&scan_files): Use "@list" instead of join.
10382 * doc/Makefile.am (CLEANFILES): Add *.fns.

10387 Remove, replaced by...
10388 * tests/wrappl.in: Be common for all the Perl executables.
10389 In particular autoscan and autoheader want -I.
10390 * configure.ac: Adjust.
10391 * lib/autoscan/headers: errno.h is portable.
10393 2001-11-26 Akim Demaille <akim@epita.fr>

10420 Test groups are now run two directories deeper.
10422 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,

10425 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10426 top_srcdir, builddir and top_builddir.
10427 Use `at_*dir' relatively to the directory containing the
10428 suite, use `*dir' when relatively to the current group dir.

10437 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10439 * doc/autoconf.texi (Using System Type): Add an example of `case
10440 $host' usage so people quit using `case $target' everywhere.
10442 2001-11-22 Akim Demaille <akim@epita.fr>
10444 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10445 spotted by Jim Meyering.
10447 2001-11-16 Paul Eggert <eggert@twinsun.com>
10449 This patch implements a `long double' suggestion by Oliver Kiddle.
10451 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10452 static, to catch errors if the value isn't known at compile-time
10453 and the compiler supports dynamic arrays. Change its name from
10454 `_array_' to `test_array' to avoid potential name clashes.
10455 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10456 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10457 better than double. Catch a bug in GCC 2.95.2 x86.
10458 * doc/autoconf.texi (C Compiler): Document the above.
10461 2001-11-13 Akim Demaille <akim@epita.fr>
10463 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10465 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10467 2001-11-13 Akim Demaille <akim@epita.fr>
10469 * lib/autotest/general.m4 (AT_INIT): After having run the test
10470 group, go back to the initial directory, not to at_suite_dir.
10472 2001-11-13 Akim Demaille <akim@epita.fr>
10474 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10475 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10476 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10478 (AT_CHECK_CONFIGURE): Use absolute paths.
10479 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10480 The problem is still the old one: there is no means in M4 (that I
10481 know about) to create a defining macro, because there is no means
10482 to create `$1' etc., therefore, the defining macro ``swallows''
10483 all the arguments meant to the defined macro.
10485 2001-11-13 Akim Demaille <akim@epita.fr>
10487 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.

10494 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10495 variable names when referring to a single test group, or to
10496 `suite' when referring to the whole test suite.
10497 `at_last_test' is removed: m4 compute at_format itself.
10498 (at_stdout, at_stder1, at_stderr): New variables.
10499 (AT_CHECK): Use them.
10501 2001-11-13 Akim Demaille <akim@epita.fr>
10503 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10505 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10506 Do it as soon as a test fails, don't wait till the end of the test
10508 Don't remove $as_me.[0-9]*, since these files no longer exist.
10510 2001-11-13 Akim Demaille <akim@epita.fr>
10512 * tests/tools.at: Use absolute paths, since we are no longer run
10515 2001-11-13 Akim Demaille <akim@epita.fr>
10517 Now that tests are running in their own private dir, there is no
10518 need to list the files to remove at the end of tests groups.
10520 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10521 (AT_data_files, at_data_files): Remove.
10522 (AT_CLEANUP, AT_DATA): Simplify.
10524 Remove the group dir if !debug && !failed.
10525 * tests/atspecific.m4: Adjust.
10527 2001-11-13 Akim Demaille <akim@epita.fr>
10529 Start a new layout for Autotest: `testsuite' creates
10530 `testsuite.dir' in which the at-check-line etc. files are to be
10531 found, and `testsuite.dir/003' where the test group 3 is run.
10533 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10534 at_check_line_file, at_format, at_test_normalized, at_group_dir
10536 Create the directories.
10537 Use absolute paths for at- files.
10538 (AT_CHECK): Adjust.
10540 2001-11-11 Michael Matz <matz@kde.org>
10542 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10544 (m4_car): Properly quote arguments.
10546 2001-11-13 Akim Demaille <akim@epita.fr>
10548 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10549 with stricter rules on LIBOBJS.
10551 2001-11-12 Paul Eggert <eggert@twinsun.com>

10575 2001-11-12 Akim Demaille <akim@epita.fr>
10577 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10578 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10579 definition used by Automake where LEX is +/- "${missing} lex" and
10580 `missing' itself contains variables.
10582 2001-11-12 Akim Demaille <akim@epita.fr>
10584 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10585 Now that M4sh pushes BODY, the comments were output at the end of
10588 2001-11-08 Akim Demaille <akim@epita.fr>
10590 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10591 that we can trace macros from aclocal.m4.
10592 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10593 obsoleted, and redirect to the former anyway.
10594 Reported by Ralf Corsepius.
10596 2001-11-08 Akim Demaille <akim@epita.fr>
10598 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10599 processed only if present.
10600 * tests/torture.at (Configuring subdirectories): Use autoreconf
10601 instead of successive calls to autoconf.
10602 Add a nonexistent subdirectory to exercise the patch above.
10603 Reported by Ralf Corsepius.
10605 2001-11-08 Kevin Ryde <user42@zip.com.au>
10607 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc

10626 * tests/Makefile.am (testsuite): Rename this target as...
10627 ($(TESTSUITE)): this.
10630 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10632 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10633 the --prefix option, also remove it's argument.
10635 2001-11-05 Akim Demaille <akim@epita.fr>
10637 * doc/autoconf.texi (testsuite Invocation): Update.

10649 Use and export them.
10650 (&find_configure_ac): Optionally take a directory where to look at.
10651 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10653 Default @ARGV to `.', not find_configure_ac.
10654 (&autoreconf): Argument is a directory.
10655 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10656 * doc/autoconf.texi (autoreconf Invocation): Update.
10658 2001-11-03 Akim Demaille <akim@epita.fr>
10660 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10661 (@export_forward_subs): New.
10662 Add basename, dirname, and fileparse.
10664 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10665 Don't look for aclocal flags if we already know aclocal is not
10667 Move aclocal.m4t only if it exists.
10668 Reported by Ezra Peisach.
10670 2001-11-03 Akim Demaille <akim@epita.fr>
10672 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10673 passed on command line, defaulting to ./configure.ac if present.
10674 (&maybe_autoreconf, File::Find): Remove, unused.
10675 (&autoreconf): If autoconf is not used, don't try to trace.
10677 2001-11-02 Akim Demaille <akim@epita.fr>
10679 * configure.ac: Bump to 2.52g.
10681 2001-11-02 Akim Demaille <akim@epita.fr>
10685 2001-11-02 Akim Demaille <akim@epita.fr>

10688 * config/lispdir.m4: Update from masters.
10689 * configure.ac: Bump to 2.52f.
10691 2001-11-02 Akim Demaille <akim@epita.fr>

10698 2001-11-01 Paul Eggert <eggert@twinsun.com>
10700 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10701 be invoked before _AS_LINENO_PREPARE.
10702 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10703 than character ranges.
10705 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10706 invoking AS_BASENAME. Set the locale variables to 'C' if
10707 possible, as POSIX requires this to get the traditional
10709 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10711 2001-10-31 Paul Eggert <eggert@twinsun.com>
10713 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10714 with {}, as that triggers a bug in Bash 2.05.
10716 (_AS_LINENO_PREPARE): Use Sed rather than
10717 Awk. Fix the sed prepass to work even if there are multiple
10718 instances of $LINENO on the same line. Do not substitute for
10719 other variables like $LINENOT. Do not check file dates; such a
10720 check is unreliable on sufficiently fast machines, and removing
10721 the check makes the code simpler and more reliable. Check for
10722 output and chmod failures.
10724 * doc/autoconf.texi (Special Shell Variables): Document
10727 2001-10-31 Akim Demaille <akim@epita.fr>

10732 2001-10-31 Akim Demaille <akim@epita.fr>
10734 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10735 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10736 provided, while it is optional.
10737 * configure.ac: Adjust.
10739 2001-10-26 Paul Eggert <eggert@twinsun.com>
10741 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10742 lib/Autom4te/Struct.pm:
10743 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10746 * doc/autoconf.texi (Special Shell Variables): Document some
10747 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10749 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10750 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10751 eval $LINENO is not portable in practice.
10753 2001-10-24 Akim Demaille <akim@epita.fr>
10755 * lib/Autom4te/General.pm (backname): New.
10757 2001-10-24 Akim Demaille <akim@epita.fr>
10759 * m4/: Remove, merged into...

10764 * doc/autoconf.texi (Shellology): Mention the problems with bash
10765 2.05's use of ANSI quoting in its `set' builtin.
10767 2001-10-22 Paul Eggert <eggert@twinsun.com>
10769 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10770 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10771 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10772 POSIX decided to standardize on the int flavor of strerror_r.
10773 Always do char* test, as there's no reason not to.
10774 Assign to a char* var, to catch strerror_r that returns int*.
10776 * doc/autoconf.texi (Particular Functions):
10777 Document the above changes. Also, document the fact that
10778 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10780 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10782 2001-10-20 Akim Demaille <akim@epita.fr>
10784 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

10787 2001-10-20 Akim Demaille <akim@epita.fr>
10789 * lib/Autom4te/General.pm (&update_file): If destination is
10790 unchanged, remove the source.
10791 (&up_to_date_p): Don't be verbose, be debug.
10792 * bin/autoreconf.in: No longer support --m4dir.
10793 (&autoreconf): Display the full path of the configure.ac we are
10795 Trace it only once.
10796 Be sure to honor --force with gettextize.
10797 Always run aclocal.
10798 * doc/autoconf.texi: Adjust.
10800 2001-10-20 Akim Demaille <akim@epita.fr>
10802 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10804 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10805 `intl' is already present, as it refuses unless --force.
10806 (&parse_args): Use -I, --include instead of the old Autoconf
10808 ($localdir, $autoconf_dir): Remove.
10810 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10812 2001-10-19 Jens Petersen <petersen@redhat.com>
10814 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

10830 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10832 * bin/autoreconf.in (autoreconf): Display the path to the
10833 configure.ac being studied.
10835 2001-10-18 Paul Eggert <eggert@twinsun.com>
10837 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10838 long, to work around a bug in the HP C compiler version HP92453-01
10841 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10842 (AS_BASENAME_EXPR): New macro.
10843 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10844 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10845 and fall back on 'sed' only if the other two fail. This makes
10846 AS_BASENAME act more like AS_DIRNAME.
10847 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10848 contains white space.
10849 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10850 Use AS_DIRNAME, since I think it's now DOS-friendly.
10851 * tests/m4sh.at (DIRNAME_TEST): New arg $3.

10863 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

10978 include handle the m4_pattern_*, no longer push the

10989 CONFIG_SHELL defaults to a shell that supports LINENO if available.
10991 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
10992 shell does not support LINENO, and if CONFIG_SHELL is unset or
10993 empty, and if we can find a shell that does support LINENO,
10994 then set CONFIG_SHELL to that shell and then re-execute
10995 ourselves with CONFIG_SHELL.
10997 2001-10-05 Paul Eggert <eggert@twinsun.com>
10999 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
11000 doesn't exist. Remove *.tmp, as a .tmp file is created during the

11300 2001-09-19 Akim Demaille <akim@epita.fr>
11302 * lib/autotest/general.m4: Englishoes.
11303 From Tim Van Holder and Alexey Mahotkin.
11305 2001-09-18 Paul Eggert <eggert@twinsun.com>
11307 * doc/autoconf.texi (Common Shell Constructs): New node,
11308 documenting AS_DIRNAME.
11309 (Limitations of Usual Tools): Refer to it when discussing dirname.
11310 Also, update discussion of POSIX standard to reflect latest draft.
11312 * lib/autoconf/c.m4:
11313 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11315 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11316 Do not pass a first argument with leading '-'
11317 to expr, by parenthesizing initial integers that might be negative.
11319 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11320 now merely checks whether it is an error to pass an argument
11323 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11324 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11325 whether it is a (compile-time) error to pass an argument to
11326 getpgrp. This simpler test supports the revised documentation,
11327 and is all that AC_FUNC_GETPGRP's users really need.
11329 2001-09-18 Akim Demaille <akim@epita.fr>
11331 * doc/autoconf.texi (Limitations of Make) <$<>: New.

11343 Add test for AS_BASENAME.
11344 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11345 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11346 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11347 * tests/base.at: Fixed the expected responses. The old ones were
11349 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11350 the documentation claims it should (and how it behaved in 2.13).
11352 2001-09-18 Akim Demaille <akim@epita.fr>
11354 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11355 the AC_CONFIG_COMMANDS invocation.
11356 This also solves the name clash problems.
11357 Don't set the package's ID.
11358 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11359 No longer to be shipped.
11360 (version.in): Remove.

11363 Use `m4_PACKAGE_STRING'.
11364 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11365 the only optional argument is the name of the test suite.
11366 Expect `package.m4' to define the package signature.
11367 * lib/autom4te.in (Autotest): Add `package.m4?'.
11368 * tests/Makefile.am (package.m4): New.
11369 * tests/suite.at: ifnames is a victim.

11374 AC_LIBSOURCE, AC_CONFIG_FILES.

11376 program version string doesn't match the package's.
11377 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

11388 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11389 Always include <stdio.h> and <stdlib.h>. Evaluate
11390 the expression in an extra function before these includes. Call
11391 fprintf "%d" only after ensuring the argument is of type 'int'.
11392 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11394 2001-09-17 Paul Eggert <eggert@twinsun.com>
11396 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11397 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11398 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11399 when they don't exist.
11401 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11402 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11405 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11406 version with the version used by fileutils 4.1, except use
11407 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11410 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11412 2001-09-13 Akim Demaille <akim@epita.fr>

11452 * lib/autotest/general.m4 (AT_INIT): Create and remove
11453 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11454 test suites can cohabit.
11456 2001-09-13 Akim Demaille <akim@epita.fr>
11458 * tests/mktests.sh: Don't output banners for empty test files.

11526 2001-09-07 Akim Demaille <akim@epita.fr>

11557 to avoid GCC warnings.
11560 2001-09-05 Akim Demaille <akim@epita.fr>
11562 * bin/autom4te.in: --language is -l, not -s.
11564 2001-09-05 Akim Demaille <akim@epita.fr>
11566 Be ready to handle filenames as stupid as `dnl.at', for if even
11567 the maintainer is dumb enough to do that...
11569 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11570 excellence in M4 quotation: consider `__file__' is active.
11572 And BTW, when invoking m4, pass the --include in the right order:
11575 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

11598 2001-09-05 Akim Demaille <akim@epita.fr>
11600 CVS GNU M4 doesn't like `undefine(undefined)'.
11602 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
11603 New, extracted from main.
11604 Use IO::File wherever possible.
11605 (input.m4): Be constant, use -I instead of hard coding $tmp.
11606 Therefore be a quoted heredoc.
11607 Don't invoke `_au_disable', since ac was not loaded, but just

11633 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11635 2001-08-31 Akim Demaille <akim@epita.fr>
11637 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11638 (testsuite Scripts): There is no such thing as `atconfig.in'.
11639 And actually one diagram is missing: test suite runtime.
11641 2001-08-31 Akim Demaille <akim@epita.fr>
11643 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11646 2001-08-31 Akim Demaille <akim@epita.fr>
11648 * bin/autoupdate.in (@include): `installcheck' revealed the path
11649 to m4sugar was lacking!
11651 2001-08-31 Akim Demaille <akim@epita.fr>
11653 * man/Makefile.am (.x.1): We really have to pass
11654 autom4te_perllibdir.

11664 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11665 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11666 Use directly autom4te, not autoconf.

11669 2001-08-31 Akim Demaille <akim@epita.fr>

11692 (autoheader): Pass --force since the test suite goes too fast for
11694 Adjust to the new autoheader messages.

11708 Drop AC_MACRODIR dead for real.
11709 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11710 `autoheader: `config.hin' is created'.
11711 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11713 2001-08-31 Akim Demaille <akim@epita.fr>
11715 * bin/autoheader.in: Rewrite in Perl.

11721 Map --localdir, --autoconf-dir onto it.
11722 Forward autom4te's options instead of interpreting them.
11723 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11724 There is no such envvar since the inception of autom4te.cfg.
11725 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11726 * bin/autoupdate.in: Adjust, and perform more control.

11728 * tests/autoconf: Dittowise.
11730 2001-08-31 Akim Demaille <akim@epita.fr>

11746 * lib/Autom4te/General.pm (&find_peer): Remove.
11747 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11748 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11749 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11750 find the executables for it.
11751 * tests/Makefile.am: Major cleanup. Too lazy to document...
11752 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11754 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11755 indeed related to running the test suite, while passing
11756 --autoconf-dir and others is related to running non installed
11757 Autoconf executables. So don't do that, leave it to...
11758 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11759 * tests/autoscan: New.
11760 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

11776 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11777 Suggested by Paul Eggert.
11779 2001-08-29 Akim Demaille <akim@epita.fr>
11781 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11782 download in a tmp dir.
11784 2001-08-29 Akim Demaille <akim@epita.fr>
11786 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

11806 foo=`(command) 2>/dev/null`

11810 (AT-devnull): this.

11847 * lib/autotest/general.m4 (AT_INIT): Log the command line.

11956 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11957 the name of the directory they're in, instead of the filename,
11958 since version.m4 is now in m4sugar, but m4_acversion must not be

12168 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

12186 * doc/autoconf.texi: Work around Texinfo buglets.
12187 (Transformation Rules): One example is enough, users are expected

12191 2001-08-17 Akim Demaille <akim@epita.fr>
12193 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

12246 autom4te.cache (it's a directory, not a file.

12249 2001-08-15 Akim Demaille <akim@epita.fr>
12251 * bin/autom4te.in (@m4_warning): New.
12252 (&handle_m4): Use it.
12253 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12254 warnings are issued at each run.
12255 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12256 is in the src tree.
12258 2001-08-15 Akim Demaille <akim@epita.fr>

12261 don't waste time running `autoupdate --version' works.
12262 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
12264 2001-08-13 Akim Demaille <akim@epita.fr>

12323 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12325 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12326 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12327 * doc/autoconf.texi (C Compiler Characteristics): Update
12328 documentation for AC_C_BIGENDIAN.
12330 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12332 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12333 magic values from an object file when cross-compiling.
12334 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12336 2001-08-10 Akim Demaille <akim@epita.fr>
12338 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12340 Suggested by Russ Allbery.
12342 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12344 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12345 current $prefix to the sub-configures.
12347 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12349 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12350 extension (needed on BeOS). Reported by Guido van Rossum.
12352 2001-08-09 Akim Demaille <akim@epita.fr>
12354 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12356 2001-08-07 Akim Demaille <akim@epita.fr>
12358 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12360 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12361 No need to remove the files before and after the each test, before
12362 each test and at the end of the suite is enough.
12363 Display only the children `times', not the shell's.
12364 If the test failed or was skipped, at-times is not available.
12366 2001-08-07 Akim Demaille <akim@epita.fr>
12368 Always produce testsuite.log, including when there are no
12369 failures. This helps getting information on skipped tests, and
12370 duration of the tests. Err, implement the latter btw.
12372 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12373 Dump information on the first run of each test.
12374 (AT_CLEANUP): Create `at-times' containing the duration of the
12377 2001-08-07 Akim Demaille <akim@epita.fr>
12379 The use of `dumpstat' revealed that `len' was used although it
12380 should not. m4_text_wrap was using it, but in the Autoconf world
12381 where it is legal. Hence (i) test M4sh in its own world, not
12382 Autoconf's, and (ii), ahem, fix the bug :)
12384 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12385 does not like `' instead of [].
12386 (AT_INIT): Forbid `^_?AT_'.
12387 And don't output such tokens.
12388 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12389 `script.as', and `autom4te.cache'.
12390 Remove `empty' and `macro' which are no longer used.
12391 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12392 * tests/m4sugar.at: Use it.
12393 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12395 2001-08-07 Akim Demaille <akim@epita.fr>
12397 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12399 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12401 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12403 2001-08-04 Akim Demaille <akim@epita.fr>
12405 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)

12408 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12409 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12410 (AC_F77_MAIN): Likewise.
12412 2001-08-04 Akim Demaille <akim@epita.fr>
12414 Don't rely on M4sugar outputting the patterns in files, since we
12415 might process the output _without_ running m4, hence without these
12418 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12419 * bin/autom4te.in (@Request::includes): Remove, unused.
12420 (@Request::source): Rename as...
12421 (@Request::input): this.
12422 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12423 (&handle_output): Fetch the patterns from the traces.
12424 `$forbidden' and `$allowed' are constant: use m//o.
12425 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12426 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12428 2001-08-04 Akim Demaille <akim@epita.fr>
12430 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12431 autoconf', i.e., in addition to caching traces, cache the output.
