76 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
77 about Solaris /bin/printf '%010000x' 123. Problem reported by

82 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
83 for a.* when searching for executables, as this prevents users
84 from having files like a.c. Problem reported by Ralf Wildenhues in:

96 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
97 AC_CHECK_TYPE, AC_CHECK_TYPES.
98 * doc/autoconf.texi (Generic types): C types must be type-names
99 (the C terminology), not type-ids (the C++ term). C++ types
100 must not be anonymous.
101 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
102 for C++; this drops support for anonymous struct and union types,
103 which were problematic anyway.
104 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
107 2007-04-12 Jim Meyering <jim@meyering.net>

119 * doc/autoconf.texi (Generic Types): Document the restrictions
120 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
121 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
122 with objects too. Document the restrictions on its use.
123 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
124 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
125 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
126 works but the latter doesn't, then it's a valid type.
127 This lets people use function types and so forth.
128 For C++ there doesn't seem to be a simple solution, so leave it alone.
129 (AC_CHECK_SIZEOF): Allow argument to be a variable.
130 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
131 AC_CHECK_TYPE; that wasn't documented or necessary.
133 2007-04-11 Stepan Kasal <kasal@ucw.cz>
135 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

184 nonstandard grep R.E. escape sequences.
186 2007-03-17 Jim Meyering <jim@meyering.net>
188 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
189 (Limitations of Usual Tools): Also list \< and \>, and mention that
190 HP-UX's grep, like the one from Solaris, does not support that syntax.
192 2007-03-09 Stepan Kasal <kasal@ucw.cz>
194 * doc/autoconf.texi (Specifying Names): `--host' does not
195 change the build type.

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

326 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
328 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
329 early on the reader side, drop stderr of the input to avoid
330 `broken pipe' error output; this may happen even with shell
331 builtin `echo' of some bash versions. Reports by Ian Macdonald
332 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
334 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

349 discussion about the allow_superuser_privileges example,
350 and change it a bit to make things clearer.
351 (Optimization and Wraparound): Clarify whether the compiler
352 will generate an infinite loop for the example derived from
353 Autoconf's mktime test.
354 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
355 Also, clarify unsigned multiplication overflow.
357 2007-01-04 Eric Blake <ebb9@byu.net>
359 * bin/Makefile.am (RELEASE_YEAR): New macro.

369 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
371 * doc/autoconf.texi (Integer Overflow): Revised based on today's
372 feedback. The most important changes document what happens when
373 you convert an out-of-range value to a signed integer type, and
374 say that (sum < a) != (b < 0) reliably detects overflow when sum =
377 * doc/autoconf.texi (Integer Overflow): Greatly expand and
378 rewrite, taking notions from the recent discussion on the gcc and
379 autoconf mailing lists; please see
380 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
381 and follow the many links.
382 (Integer Overflow Basics, Signed Overflow Examples):
383 (Optimization and Wraparound, Signed Overflow Advice):
384 (Signed Integer Division): New sections.
386 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
388 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
389 preprocessor macro arguments in traced name.
390 * doc/autoconf.texi (Defining symbols): Document longstanding
391 support for AC_DEFINE-ing macros with arguments, and document
392 behavior when the same variable has multiple AC_DEFINEs.
393 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
394 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
395 macros directly, giving much shorter and simpler code.
397 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
399 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
400 space before "$ac_configure_args" to prevent a 'config.status
401 --recheck' failure if ac_configure_args doesn't contain a leading
402 space. This works around a problem with the XEmacs configure.ac,
403 which uses the (undocumented) ac_configure_args variable
404 inconsistently with Autoconf.
406 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
408 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
409 Include <limits.h>, and use its INT_MAX to rewrite the
410 j loop so that it does not overflow 'int'. Problem reported by
412 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
413 Play it safe by shifting left by 1 rather than multiplying by 2,
414 as GCC is less likely to optimize this away when the value
415 is signed (when it assumes overflow leads to undefined behavior).
416 Also, don't assume time_t uses two's complement.
418 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
420 * tests/torture.at (Substitute a 2000-byte string): Avoid using
421 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
422 dumps core on it. Report by Tim Rice.
424 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
426 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
427 --disable-option-checking to --help output even when

441 (External Software, Package Options): Cross-reference to Option
442 Checking, and use this to shorten our section.
443 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
444 "$x" to test "x$foo" != x.
445 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
446 Don't warn if $enable_option_checking is "no".
447 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
448 ac_unrecognized_opts to the empty string.
449 Don't echo the unrecognized opts, as this might mishandle
450 backslashes or leading -.
451 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
452 usage next to the other --disable-FEATURE options in the
455 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
457 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
458 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
459 Print warning for unrecognized --with and --enable options
460 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
461 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
462 Disable option checking when subdirs are configured.
463 (AC_OUTPUT): If warnings are enabled, print warning about
464 unrecognized --with and --enable options at the end of
465 the configure output (as well as at the beginning).

476 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
477 Define HAVE_GETMNTENT to 1, not to the empty string.
478 Problem originally reported by Jochen Friedrich in
479 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
481 This change prompted by a problem report by Andrey Simonenko in
482 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
483 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
484 object-like macros only, in the traditional portable character
486 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
487 Warn about attempts to define things that are not identifiers.
488 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
489 awful hack that AC_DEFINEd macro names containing parentheses.
491 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
493 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
494 too drastic, even if Texinfo in theory requires it for info mode.
496 (config.status Invocation): Renamed back from Recreating a
498 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
499 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.

510 variables, and the AC_FUNC_FSEEKO fix.
512 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
514 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
515 Writing configure.ac.
516 (Autoconf Input Layout): Renamed from configure.ac Layout.
517 (Recreating a Configuration): Renamed from config.status Invocation.
518 (Obsolete Recreation): Renamed from Obsolete config.status Use.
519 (acconfig Header): Renamed from acconfig.h.
520 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
521 (Writing Testsuites): Renamed from Writing testsuite.at.
522 (Autom4te Cache): Renamed from autom4te.cache.
524 * BUGS: Remove mention of VPATH problem, since it's now documented
525 not to be a bug in the Autoconf build procedure itself, but rather
526 a problem with the proprietary `make' programs.
528 * doc/autoconf.texi (Build Directories): Add a cross reference
531 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
532 * doc/standards.texi: Sync from gnulib.
534 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
535 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
536 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
537 generated automatically.
539 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
541 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
542 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
543 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
545 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
547 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
548 `CEOF$ac_eof' special marker, the awk script cannot contain a
549 line matching `^CEOF', so this is not needed any more.
550 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
551 special marker in the test.
553 2006-12-06 Stepan Kasal <kasal@ucw.cz>
555 * tests/tools.at (autom4te preselections): Use `find -newer';
556 remove one of the sleeps.
558 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
559 more readable, using ...
560 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
562 * doc/autoconf.texi (autoheader Invocation): Do not double-
563 quote the parameter of `AH_BOTTOM' in the example.
565 2006-12-05 Stepan Kasal <kasal@ucw.cz>
567 * doc/autoconf.texi (Configuration Headers): Remove the
568 example with multiple input files.
569 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
570 multiple input files.
572 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
574 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
575 creating the awk substitution script, handle one input line at a
576 time, so that the maximum length of a substituted (multi-line)
577 value is not limited by the size of the sed pattern space.
578 The trade-off is a slightly repetitive sed script.
579 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
580 can only have up to 7 characters, due to Solaris 10 /bin/sed.
581 * tests/torture.at (Substitute a 2000-byte string): Increase the
582 test with several long lines, they should not be caught by sed
585 * tests/tools.at (autom4te preselections): New test, to flag
586 entries missing from autom4te.cfg.
587 Report by David Byron <dbyron@hheld.com>.
589 * tests/torture.at (Substitute a 2000-byte string): Actually use
590 AC_PROG_AWK, so the last change works as intended.
591 (Substitute and define special characters): Likewise.
592 (Substitute a newline): Likewise.
594 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
595 instead of `awk' consistently.
596 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
597 * tests/torture.at (Torturing config.status): Test both the
598 result of AC_PROG_AWK and plain awk.
599 (Substitute a 2000-byte string): Likewise.
600 (Substitute and define special characters): Likewise.
601 (Substitute a newline): Likewise.
603 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
605 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
606 can be assigned to a function pointer. Problem reported by
607 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
608 part of a patch by Ralf Wildenhues in that same bug report.
610 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
612 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
613 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
615 2006-12-01 Eric Blake <ebb9@byu.net>
617 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
618 cross-compiling from cygwin to mingw.
619 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
620 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
621 to lib/autoconf/c.m4.
623 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
625 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
626 string for more reliable failure. Wrap the entire test that
627 causes the broken Solaris printf to dump core, in a subshell,
628 so the segmentation fault message is reliably suppressed.
629 Fix shell expansion errors by using /usr/ucb/echo always;
630 avoid an error on systems without it by another subshell.
631 Avoid m4 expansion of `$1'. Set the zeroth argument of the
632 subshell-$as_echo to `as_echo', for better error message.
634 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
636 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
637 `BASH_SOURCE' contain a newline, set them to empty, as they may
640 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
642 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
643 years and is too hard to maintain now. The last straw was
644 reported by Jerker Baeck in
645 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
646 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
647 * doc/autoconf.texi (Particular Functions): Move
648 AC_FUNC_SETVBUF_REVERSED from here...
649 (Obsolete Macros): ... to here. Say that it does nothing now.
650 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
651 Turn into (almost) a no-op.
653 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
655 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
656 These macros are obsolescent and new applications shouldn't need them.
657 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
658 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
659 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
660 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
661 (AC_FUNC_VPRINTF): Likewise.
662 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
663 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
664 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
666 * doc/autoconf.texi (Setting Output Variables): Mention that
667 @VAR1@VAR2 has unspecified behavior. Problem reported by
669 * NEWS: Mention this.
671 * Makefile.am: Put only a single '#' into the copyright notice,
672 so that it's also present in the output file. Standardize wording
673 in makefile copyright notices to match GNU coding standards.
674 * bin/Makefile.am: Likewise.
675 * doc/Makefile.am: Likewise.
676 * lib/Makefile.am: Likewise.
677 * lib/freeze.mk: Likewise.
678 * lib/autoconf/Makefile.am: Likewise.

682 * man/Makefile.am: Likewise.
683 * tests/Makefile.am: Likewise.
684 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
687 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
689 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
690 in the sed script that mangles the awk script: delete up to the
691 first exclamation mark only.
692 * tests/torture.at (Substitute and define special characters):
695 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
697 Rewrite config files generation: avoid quadratic growth in
698 the number of substituted variables by using awk instead of sed
699 for the bulk of the substitutions.
700 * NEWS: Mention this.
701 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
702 forbidden in the output (and thus input) file.
703 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
704 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
705 generate just one large awk script for substitutions,
706 eliminating much of the earlier complexity, while adding some
707 new complexity. Only expand the substitution templates at
708 configure time, for smaller configure script size. If
709 _AC_SUBST_FILES are used, test 'awk' for working getline support
710 at config.status time. If absent, interpolate through the
711 shell. The awk script was written with much help
712 from Paolo Bonzini and Paul Eggert.
713 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
714 (_AC_SED_FRAG_NUM): Likewise.
715 (_AC_SUBST_CMDS): Renamed from...
716 (_AC_SED_CMDS): ...this.
717 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
718 * tests/torture.at (Substitute a 2000-byte string): Also
719 substitute a line with 1000 words, and a variable with several
721 (Substitute and define special characters): Test awk special
722 characters, and put substitution input strings `@foo@' in the
723 output, to test that no recursion happens; test several other
724 combinations from Paolo Bonzini.
726 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
728 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
729 that replaced echo with AS_ECHO where this wasn't necessary.
730 Problem reportd by Ralf Wildenhues.
731 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
732 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
733 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
735 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
737 * lib/freeze.mk (GREP): Removed, no need to initialize this.
739 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
741 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
742 that traditional Awk lacks 3-arg "split". It has it.
743 Mention that FS must be a single character, and a few other
744 99-byte limits of traditional Awk.
745 Mention that if (i in a) doesn't work with traditional Awk.
747 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
749 * tests/autotest.at (BSx641-newline in command):
750 (BS-BS-newline in command, BSx640-newline in command):
751 (Newline-CODE-BS-newline in command):
752 (Single-quote-BS-newline in command):
753 (Single-quote-newline-BS-newline in command):
754 Use printf '%s\n' instead of echo, for portability to hosts
755 where echo interprets backslashes. This will break on hosts
756 that lack printf, but for now let's assume all such hosts
757 are dead (if not, we should get reports of test failures).
759 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
761 'echo' has some portability problems, when given a first argument
762 with a leading '-', or when given any argument containing '\'.
763 Avoid using 'echo' in these cases.
764 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
765 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
766 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
767 * lib/autotest/general.m4 (AT_INIT): Likewise.
768 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
769 argument might be unportable.

784 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
785 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
786 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):

788 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
789 * bin/autoconf.as: Redo verbose flag implementation, as the old
790 scheme wouldn't work with AS_ECHO.
791 * lib/autotest/general.m4 (AT_INIT): Likewise.
792 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
793 Don't use ECHO_T, since ECHO_N is now reliable.
794 * lib/autotest/general.m4 (AT_INIT): Likewise.
795 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
796 rather than using a here-document to put the script into a file.
797 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
799 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
800 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
801 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
802 bug, but we might as well stop using ECHO_N and ECHO_C internally.
803 * lib/autotest/general.m4 (AT_SETUP): Likewise.
804 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
805 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
806 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
807 operand, as AS_ECHO requires. Avoid double file name expansion.
808 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
809 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
810 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
811 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
812 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
813 Double-quote strings that would otherwise contain M4 comments.
814 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
816 * configure.ac (AC_INIT): Bump to 2.61a.
819 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
823 * configure.ac (AC_INIT): Bump to 2.61.
826 * tests/autotest.at (Macro with backslash in a test title):
827 Comment out for now, as this tests neither fails nor passes
828 reliably. Problem reported by Ralf Wildenhues.
830 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
832 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
833 in previous change, which caused test failures.
835 2006-11-16 Stepan Kasal <kasal@ucw.cz>
837 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
838 code for --enable, --disable, --with, and --without to...
839 (_AC_INIT_PARSE_ENABLE): ... a new macro.
840 * doc/autoconf.texi (Package Options):
841 * NEWS: Document that AC_ARG_ENABLE allows dots, too.

980 5363) simply issues a warning when dividing by zero at compile
981 time. Problem reported by Elias Pipping.
983 2006-10-26 Eric Blake <ebb9@byu.net>
986 * doc/autoconf.texi (Evaluation Macros): Improve the example to
987 show effect on macros that expand with commas.

1012 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
1014 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1015 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1016 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1017 reported by Nelson H. F. Beebe for Coreutils 6.4.
1019 * tests/tools.at (autoconf --trace: user macros): Remove test
1020 for tracing multiline macros, since m4 1.4.7a uses a different
1021 way to number lines. Problem reported by Ralf Wildenhues.
1023 2006-10-24 Stepan Kasal <kasal@ucw.cz>
1025 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1026 /dev/null since the heuristics for interactive behaviour was

1048 * doc/autoconf.texi (Caching Results): Likewise.
1049 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
1050 AC_CACHE_CHECK_INT, since it's no longer public.
1051 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1052 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

1097 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1099 (Imported from Automake.)
1100 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1101 which incorrectly sets the mode of an existing destination
1102 directory. In some cases the unpatched install-sh could do the
1103 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1104 system. We hope this is rare in practice, but it's clearly worth
1105 fixing. Problem reported by Alex Unleashed in
1106 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1107 Also, don't bother to check for -m bugs unless we're using -m;
1108 suggested by Stepan Kasal.

1156 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1157 added to the template can get mangled.
1159 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1161 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1162 include the default headers, and redefine obstack_chunk_alloc
1163 and obstack_chunk_free. Fixes false failure with glibc.
1165 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1167 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

1180 the NonStop platform.
1181 * doc/autoconf.texi (Posix Variants): Likewise.
1182 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1184 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1185 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1186 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1187 Use a better substitute, by inspecting the output of "ls"
1188 rather than just using ":".
1189 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1190 rather than AS_EXECUTABLE_P, since we needn't worry about
1191 non-regular files here.
1193 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1194 due to configuration hassles with this. See Tonya Underwood's report

1207 initialization which is not inherited through the environment
1208 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1209 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

1218 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1219 comment about ac_cpp_err; it was incorrect, and anyway
1220 ac_cpp_err is being removed below.
1221 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1222 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1223 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1225 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1226 with werror_flag and conftest.err and so forth. This is more
1227 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1228 and anyway the user shouldn't normally want to see this gorp logged.
1229 Problem reported by Ralf Wildenhues.
1230 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1231 empty, not 'no', since the rest of the code uses 'test -z'.

1235 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1236 Use a single call to AC_DO_TOKENS rather than multiple, for

1239 Problem reported by mwoehlke in
1240 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1242 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1243 than creating a file to use with test -x; this is much faster.
1245 2006-10-02 Bruno Haible <bruno@clisp.org>
1247 * lib/autom4te.in (Automake-preselections): Add
1248 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1250 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1252 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1253 standard error, `experr' should be used, not `expout'.

1257 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1258 fseeko testing program twice; just use the earlier result.
1259 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1260 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1261 still doesn't let the program compile.
1262 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1265 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1266 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1267 include it, without including anything else.
1268 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1270 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

1275 `error.h', and include it, for a `error_at_line' prototype.
1276 Use a nonempty format string in the link test.
1277 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1278 for a declaration of wait3.

1284 can apply to constants too, and that it checks for macro defns.
1285 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

1287 values. Problem reported by Ralf Wildenhues.

1449 except the first two arguments are reversed.

1462 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
1463 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
1464 programs should use their Gnulib counterparts.

1502 broken lex libraries like native ia64-hp-hpux11.22; see
1503 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1504 work around the problem by preferring an empty LEXLIB to -lfl or
1505 -ll. Let the user set LEXLIB='' to indicate no library needed.

1632 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1633 -Wundef -Werror". Problem reported by David Fang in
1634 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

1656 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1657 problems with arg script text that doesn't end in newline, and

1694 less skeptical about "volatile", after discussion with
1695 Bruno Haible on bug-gnulib.

1706 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1707 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1709 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1711 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1712 after -R regardless of host. Patrick Welche reports that this

1724 under AC_C_VOLATILE.
1725 (Volatile Objects): Be a little less skeptical about what
1726 "volatile" means. Derived from thoughts by Ben Pfaff in
1727 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1729 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1733 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1735 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1736 more globally, since the 2006-06-30 patch didn't suffice. Problem
1737 reported by Keith Marshall. Also, don't bother with builddir2,
1738 since it shouldn't be needed any more.
1740 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1742 * doc/autoconf.texi (Generic compiler characteristics):
1743 Document AC_COMPUTE_INT. Fix wrong statements on Default
1744 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

1759 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1761 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1762 Require that long long int be at least 64 bits wide. C99 requires
1763 this and enough programs depend on it so we should check for it.
1764 Bruno Haible reports in
1765 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1766 that long long int is 32 bits wide with some nonstandard compilers.

1773 a local site configuration that doesn't use /usr/local.
1774 Problem reported by Keith Marshall in
1775 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1777 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1779 * doc/autoconf.texi: Be more consistent about using @acronym with
1780 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1781 quite right (it talked about "OSF/Tru64", even though the
1782 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1783 and it even mentioned "OSF 4"!) and at this point there's little
1784 reason to talk about OSF any more, since it died in 1994.
1785 (Specific Compiler Characteristics): Simplify example of
1786 negative-size array.
1787 (File Descriptors): Reorder to make the text flow better.
1788 Remove joke about "appreciate the various levels"; I didn't get it.
1789 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1790 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1791 (File Descriptors, Limitations of Usual Tools):
1792 Tone down the advice against renaming or removing open files.
1793 (Limitations of Usual Tools): Add a new section, on 'rm'.
1795 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1797 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1798 -lXt in LIBS, idea from Karsten Hopp; this was due since
1801 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1802 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1803 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1804 (which belong to Xt, not X itself). See Debian bug 327655.
1806 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1808 * configure.ac (AC_INIT): Bump to 2.60a.

1828 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1830 * doc/autoconf.texi (Changed Directory Variables): New node,
1831 to document the whole `datarootdir' business a bit better.
1833 * tests/torture.at (datarootdir workaround): Extend test.
1834 Prompted by report by Alexandre Julliard.
1836 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1838 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1839 when using default mode of IBM C 6 for AIX. Problem and two-line
1840 fix reported by Larry Jones.
1842 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1844 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1845 about literal '${datarootdir}' if a definition is found in the
1848 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1850 * NEWS: Use "M4" rather than "m4" when appropriate.
1851 Problem reported by Eric Blake.
1852 * doc/autoconf.texi: Likewise.
1853 Use @acronym around BSD, GCC, and GNU when appropriate.
1854 (Why GNU M4): Renamed from "Why GNU m4".
1855 (Redefined M4 Macros): Mention that Posix
1856 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1857 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1860 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1862 * bin/autom4te.in (handle_output): Do not forbid the empty
1864 * tests/tools.at (autoconf: the empty token): New test.
1866 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1868 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1869 calls, so that we do not care whether they are LIFO or FIFO;
1870 in the m4_wrap, do not check which diversion is the topmost
1871 one, just check that the stack is balanced at the end.
1872 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1873 base diversion forever--pop the previous diversion before
1874 opening the new one; consequently, remove the m4_wrap call.
1875 * lib/autotest/general.m4 (AT_INIT): Likewise.
1876 * tests/m4sugar.at: Do not use
1877 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

1880 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1882 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1883 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1884 Rework example of m4wrap token-pasting trouble so that it doesn't
1885 care whether it's LIFO or FIFO.
1886 Fix some "contrary to"s that are awkward in English.
1888 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1890 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1891 to `yes' instead of `int$1_t' if the type is found, for more
1892 consistent configure output (where $1 is the number of bits).
1893 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1894 Suggested by Bruno Haible.
1896 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1897 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1898 with system headers. Report by Bruno Haible.
1900 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1902 * config/config.guess, config/config.sub: Sync from upstream.
1904 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1905 in order to avoid picking up an older installed frozen m4sh.m4f.
1906 Besides an outdated shell startup, this could have been created
1907 by an earlier M4 version with incompatible frozen file format.
1909 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1911 * README: Recommend m4 1.4.4 instead of 1.4.3..
1912 * doc/autoconf.texi: Likewise.
1913 (Special Chars in Names): Say that $(.FOO) is portable, as
1914 suggested by Stepan Kasal.
1915 (Installation Directory Variables, Build Directories):
1916 (Automatic Remaking, Subdirectories, Fortran Compiler):
1917 (Making testsuite Scripts, Defining Directories):
1918 Quote variable usages better.
1919 (Making testsuite Scripts): Add clean-local rule to makefile
1920 snippet, by Eric Blake.
1921 (Installation Directory Variables): Fix table item font.
1922 Reword slightly to clarify. Generalize advice about
1923 not using special characters to include all file-related
1924 vars, not just VPATH.
1925 (Special Chars in Variables): Warn about special characters in
1927 (Assignments): Clarify default-value example as suggested by
1929 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1930 (Special Shell Variables): Note leading ./ or ../, as suggested
1932 (Limitations of Builtins): Under cd, warn about CDPATH.
1933 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1936 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1938 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1939 `@var', for texi2html.
1940 (Systemology): Some more word wrapping, for DVI output.
1941 (autom4te Invocation): The short option for `--melt' is `-M',
1944 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1946 * doc/autoconf.texi: More formatting and English tweaks,
1947 many suggested by Ralf Wildenhues.
1948 Reword to avoid "@code{...}'s" and the like, since it's ugly
1949 with Emacs info mode. discontents -> woes.
1950 Put a few "will"s back. time stamp -> timestamp.
1951 side-effect -> side effect.
1953 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1955 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1956 Warn about $@ not persisting. Problem reported by Julien Danjou in
1957 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1958 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1959 Mention other special chars, too.
1961 2006-06-14 Eric Blake <ebb9@byu.net>
1963 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1965 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1967 * doc/autoconf.texi: Some systematic minor improvements, as
1968 follows. Use "makefile" when talking about makefiles
1969 generally (which might be named "makefile" or "Makefile" or even
1970 "foo.mk"), "Makefile" when talking about a specific makefile
1971 called "Makefile". This unclutters the text from weird quotes
1972 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1973 values" rather than "@var{foo}s" and similar constructs containing
1974 "}s". Use "Make rules" rather than "Makefile rules". Minor
1975 English-language improvements. Change the prefix "sub-" to "sub"
1977 Put blank lines around examples more consistently.
1978 Avoid "rather" and "very" as intensifiers.
1979 Avoid "will" as an auxiliary.
1980 (Limitations of Make): Split this node into....
1981 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1982 (Leading _ in Macro Names, Backslash-Newline-Newline):
1983 (Backslash-Newline Comments, Long Lines in Makefiles):
1984 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1985 (obj/ and Make, make -k Status, VPATH and Make):
1986 (VPATH and Double-colon, $< in Explicit Rules):
1987 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1988 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1989 New nodes, resulting from splitup of Limitations of Make.
1990 All cross-references changed. Raise the top node from
1991 a section to a chapter, and all subnodes accordingly.
1992 Redo the introductory wording to match the new organization.
1993 (Installation Directory Variables): Use an example that is
1994 closer to what Autoconf actually does. Mention that VPATH's
1995 value should not contain metacharacters or white space.
1996 (Fortran Compiler): Fix a VPATH bug in an example.
1997 (Leading _ in Macro Names): Mention that this problem is no longer
1998 of practical concern.
1999 (VPATH and Make): Reword the advice to make it clearer
2000 that Autoconf and Automake support VPATH in non-GNU make, but
2001 many packages have bugs in this area.
2002 ($< in Explicit Rules): Refer to Build Directories rather
2003 than using a (non-VPATH-safe) example.
2004 (Automatic Rule Rewriting): Mention the sort of disaster that
2005 can ensue with Solaris-style rule rewriting with VPATH.
2007 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2009 * doc/install.texi (Compilers and Options): Weaken the
2010 suggestion to use GNU make for VPATH builds.
2012 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2013 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2015 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2016 in regular expression.
2018 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2020 * doc/autoconf.texi (Installation Directory Variables):
2021 Drop extra @samp from `@table @samp' item.
2022 (Limitations of Usual Tools): Comment fix.
2023 Do not nest @samp just to point to other table items.
2024 (Writing testsuite.at) <AT_CHECK>: The second argument to
2025 `@dvar' is already @samp'ed.
2026 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2027 do not use @var in the second argument.
2029 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2031 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2032 $as_shell.exe too. Problem reported by Andreas Buening in
2033 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2035 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2037 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2038 `unused variable' compiler warning, for `-Wall -Werror'.
2039 Reported by Jaap Haitsma in
2040 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2042 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2044 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2045 case the compiler dumps core. Problem reported for
2046 OpenServer 5.0.7 by Tim Rice in
2047 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2048 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2051 2006-06-06 Tim Rice <tim@multitalents.net>.
2053 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2054 "ERROR" only shows up in "make check" output if there is an
2057 2006-06-06 Eric Blake <ebb9@byu.net>
2059 * tests/tools.at (automatically allowed tokens): Fix typo.
2061 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2063 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2065 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2066 typically overflows on x86 CPUs, even though the C standard
2069 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2071 * configure.ac (AC_INIT): Bump to 2.59e.
2074 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2078 * config/texinfo.tex: Sync from upstream.
2080 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2081 seen, invoke libtoolize with `--ltdl' argument.
2082 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2084 Suggested by Eric Blake.
2086 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2088 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2089 reported by Ralf Wildenhues.
2090 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
2092 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2096 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2098 * doc/autoconf.texi: Modernize some of the references to Solaris.
2100 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2102 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2103 message issued by AC_REQUIRE.
2104 * tests/m4sugar.at: Check m4_require's error message.
2105 * tests/base.at: Check AC_REQUIRE's error message.
2106 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2108 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2110 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2111 `expout' as the last parameter.
2112 * tests/tools.at: Adapt to the above change.
2114 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2116 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2117 information about race-free implementations of mkdir.
2119 2006-06-04 Eric Blake <ebb9@byu.net>
2121 * bin/autoreconf.in (help): Document M4 environment variable.
2122 * bin/autoconf.as (Usage): Likewise.
2123 * bin/autom4te.in (help): Likewise.
2124 * doc/autoconf.texi (autom4te Invocation): Likewise.
2126 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2128 * NEWS: GNU make now recommended for VPATH builds.
2129 Mention that some macros are now documented to be obsolescent.
2130 * doc/autoconf.texi:
2131 Prefer "current" to "modern" to describe
2132 currently-used (albeit perhaps old-fashioned) hosts.
2133 Mention which ancient features no longer need to be worried about.
2134 setgid -> set-group-ID
2135 setuid -> set-user-ID (these are the Posix terms)
2136 Fix some misuses of "only".
2137 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2138 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2139 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2140 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

2145 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2146 Mention that these macros are obsolescent.
2147 (Installation Directory Variables): shall -> should
2148 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2149 Mention that it's now safe to use 3 and 4.
2150 (Limitations of Usual Tools): cp -r is now specified by Posix.
2151 Omit longwinded and obsolescent discussion of cp -f.
2152 Modernize discussion of expr, ls.
2153 (Limitations of Make): Modernize discussion of VPATH builds.
2154 Mention $? as a workaround in some cases.
2155 * doc/install.texi (Basic Installation):
2156 Mention "./configure; make; make install" first. Be more
2157 specific about why this file is generic. Remove unnecessary
2158 parens. Remove misleading "only". Remove obsolete advice
2159 about csh. Don't say "configure" takes awhile; say it
2160 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2161 and CC=c99 rather than CC=c89, as these are blessed by current
2162 Posix. Recommend GNU make if doing a VPATH build.
2164 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2166 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2167 examples involving shell prompts.
2169 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2170 and Paul Eggert <eggert@cs.ucla.edu>
2172 * doc/autoconf.texi (Here-Documents): Add details about the
2173 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2174 use "here-documents" instead of "here documents".
2176 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2178 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2180 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2182 * doc/autoconf.texi (File System Conventions): Warn about ":"
2183 anywhere in directory names.
2185 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2187 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2188 about quoting the case statement, just in case.
2189 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2190 was fixed in ksh93g; reported by Ralf Wildenhues.
2192 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2194 * doc/autoconf.texi (System Services): Do not document
2195 overriding EXEEXT via ac_cv_exeext=ext.
2196 (Particular Programs) <AC_PROG_MKDIR_P>:
2197 Document that ${MKDIR_P} understands --.

2201 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2203 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2204 argument with leading hyphen. Problem reported by Paul Eggert.
2206 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2208 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2209 about quoting ac_try: quote all of it, if any of it seems suspicious.
2210 This means we don't have to worry about ${ or sed any more.
2211 Also, double-quote the case statement, to work around misuses via
2212 underquoting as reported by Ralf Wildenhues in
2213 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2214 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2215 undocumented and dangerous macro.
2216 Problem reported by Ralf Wildenhues in
2217 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2219 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2221 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2222 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2223 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2225 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2227 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2228 since evidently some packages rely on the old, broken behavior.
2229 Problem reported by Ralf Wildenhues in
2230 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2231 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2232 pre-2006-05-26 definitions, but leave in the comments that
2233 these macros are dangerous and should not be used.
2234 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2235 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2236 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2237 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2238 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2240 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2242 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2243 the use of 'tr', since this is our only use of 'tr'.
2245 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2246 and Paul Eggert <eggert@cs.ucla.edu>
2248 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2249 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2251 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2253 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2254 the output file in the `${datarootdir}' test.
2256 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2257 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2259 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2260 mention of `datarootdir' in the input file(s), but literal
2261 `${datarootdir}' in the output file, and we haven't warned yet,
2262 then warn as well: the user may have (erroneously) used
2263 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2264 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2265 * tests/torture.at (datarootdir workaround): Extend this test.
2268 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2269 and Paul Eggert <eggert@cs.ucla.edu>
2271 * doc/autoconf.texi (autoheader Invocation): The first argument to
2272 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2273 alternatives and clear up the language a bit.
2275 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2277 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2278 ac_config_guess, ac_config_sub, ac_configure.
2279 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2280 Fix typo that prevented an unnecessary space from being removed.
2281 Problems reported by Ralf Wildenhues in:
2282 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2284 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2286 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2287 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2288 Don't use the term "thread-safe" to talk about mkdir race
2289 conditions, since the problem is more a process than a thread
2290 issue. Problem reported by Stepan Kasal in:
2291 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2292 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2293 the test for 'install' more closely. Look at MKDIR_P first.
2294 Look in the PATH, and at /opt/sfw/bin.
2295 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2296 Don't bother to try mkdir -p, since we already check mkdir --version;
2297 just look at the version number. (There's no easy way to check
2298 for race-free implementations.)
2299 * tests/tools.at (autoconf: subdirectories): Adjust to above
2300 changes, since MKDIR_P now might end in "/mkdir -p".
2302 * doc/autoconf.texi (autoheader Invocation): Mention that the
2303 first arg of AC_DEFINE_UNQUOTED must be a literal.
2304 Problem reported by Ben Pfaff in
2305 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2307 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2308 * doc/autoconf.texi (Special Chars in Variables): New section.
2309 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2310 (Installation Directory Variables): Quote $(datadir) better.
2311 (Limitations of Builtins): Describe some of eval's trickiness.
2313 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2314 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2315 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2316 in front of every arg, not just trailing args. Quote apostrophes.
2317 (_AC_EVAL_ECHO): New macro.
2318 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2319 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2321 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2322 exposed by quoting of eval argument. Put the command on line line
2324 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2325 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2326 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2327 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2328 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2329 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2330 Use eval more safely.
2331 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2332 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2334 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2335 lines, exposed by quoting of eval argument.
2337 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2338 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2340 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2341 initialization of `ac_cv_exeext', do not override it if it was
2342 already set, unless it was set to `no', for compatibility with
2343 Autoconf-2.13, and comment this.
2344 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2345 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2346 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2347 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2348 Document that this test may be overridden by setting

2357 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2360 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2361 Clean up _AC_COMPILER_EXEEXT* macros.
2362 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2363 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2364 ac_file to the name of the default output file and call
2365 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2366 initial `rm' of the candidate files...
2367 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2368 the same list in subsequent `rm' calls, and for the temporary
2369 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2370 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2371 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2372 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2373 no longer needed) by libtool. Make it a cache check.
2374 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2375 copied here by mistake.
2376 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2377 _AC_COMPILER_EXEEXT.
2378 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2379 _AC_COMPILER_OBJEXT directly.
2380 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2382 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2384 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2385 Fix description of how the buggy `sed' works.
2387 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2391 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2392 ENOLCK. Only mention `make -j' when applicable. Only raise
2393 fatal errors when `make -j' is involved. Improve error message.
2395 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2397 * doc/autoconf.texi (Here-Documents): We now know more about
2398 the variable expansion in here documents bug.
2399 Thanks to Tim Rice and Stepan Kasal.
2401 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2402 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2404 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2406 * tests/autotest.at (Multiline command from M4 expansion):
2407 No failure to be expected if the shell quotes newlines in
2408 commands in the `set -x' output. Report by Tim Rice.
2411 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2413 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2414 expansion in the here-documents used by config.status, as that
2415 runs afoul of the Korn shell version M-12/28/93d bug described in
2416 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2417 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2418 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2420 2006-05-23 Jim Meyering <jim@meyering.net>
2422 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2423 Fix typo introduced with 2006-04-02 change. It reversed the sense
2426 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2428 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2429 ac_dB slightly, to save bytes in the script.
2430 Max out at 50 lines, rather than 96; this is more likely
2431 (though not guaranteed) to avoid obscure 'sed' failures.
2433 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2435 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2436 `tr -d -' as bad option argument. Work around this by deleting
2437 an unrelated character.
2438 Report by Tim Rice <tim@multitalents.net>.
2440 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2441 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2442 Stepan Kasal <kasal@ucw.cz>
2444 * doc/autoconf.texi (Particular Programs): Do not promise that
2445 we always prefer the GNU version of the program, and that we
2446 search according to PATH; both rules can have exceptions.
2447 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2448 AC_PROG_SED. Move descriptions of limitations
2449 to the Limitations of Usual Tools section.
2450 (Limitations of Usual Tools) <sed>: Mention script length
2451 limitations with Solaris /usr/ucb/sed.
2452 <grep>: Fix wording for empty alternative. Mention that -c and
2453 -l should not be combined, and that -E and -F should not be
2456 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2457 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2459 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2460 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2462 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2464 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2465 AC_DEFINE is now passed to m4_pattern_allow.
2466 * NEWS: Mention that; likewise for AC_SUBST.
2467 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2468 the parameter to m4_pattern_allow.
2469 * tests/tools.at: Add a check for that.
2471 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2473 * lib/autoconf/status.m4: Fix typos.
2475 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2477 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2478 only the files that this macro generates.
2480 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2482 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2483 the HP-UX sed limitation of 99 commands, labels do not count.
2484 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2486 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2488 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2490 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2491 Import the following fix from coreutils:
2493 2006-01-13 Jim Meyering <jim@meyering.net>
2495 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2496 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2497 not double-quote uses of that variable, to accommodate the rare
2498 case in which getmntent is available in none of the libraries
2499 checked. This happens at least on FreeBSD 5.0.
2501 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2503 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2504 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2505 some other programs unwisely rely on these undocumented vars.
2506 But put in warning comments about them.
2507 Problem reported by Ralf Wildenhues in
2508 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2509 * NEWS: Document that these variables are intended to go away.
2511 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2513 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2514 and set the language to C++ (analogous to the equivalent Fortran
2517 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2518 * doc/autoconf.texi (C++ Compiler): Document it.
2519 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2522 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2524 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2525 that caused config.status to generate 100-command sed scripts; the
2526 portable limit is 99.
2528 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2530 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2531 variable `ac_d' instead of `d' to avoid infringing namespace.
2532 Report by Ralf Menzel.
2534 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2536 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2537 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2538 * tests/tools.at (autoconf: subdirectories): New test, taken from
2539 the corresponding problem report by Ralf Wildenhues in:
2540 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2542 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2543 Quote some uses of shell variables if they might suffer unexpected
2544 globbing. This doesn't fix all instances of quoting problems that
2545 I found, just the easy ones that look safe.
2546 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2547 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2548 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2549 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2550 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2551 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2552 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2554 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2555 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2557 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2559 * bin/autoreconf.in ($help): Reword according to the manual.
2560 Suggested by Olly Betts.
2562 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2563 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2565 * bin/autoreconf.in: Pass the directory argument to
2566 `require_configure_ac'. Fix comment.
2567 * tests/torture.at (Configuring subdirectories): Expose this.
2568 Reported by Olly Betts.
2570 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2572 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2573 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2574 Automake as follows:
2576 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2577 `$configure_in' instead of `configure.in', to preserve
2578 directory component.
2580 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2582 * config/config.guess, config/config.sub, config/texinfo.tex,
2583 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2585 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2587 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2588 test for C99 conformance; (bool) 0.5 is an integer constant
2589 expression, but (bool) -0.5 is not. Problem reported by Fedor
2590 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2592 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2594 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2595 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2596 Warn about obsolete install-sh files. Remove stray sentence
2597 fragment and fix cross reference.
2598 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2599 install -d; this undoes the 2006-05-10 change.
2600 (MKDIR_P): Mark with AN_MAKEVAR.
2601 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2602 that we don't require $INSTALL to be thread-safe. Move comments
2603 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2604 of AC_PROG_INSTALL. Output a message saying that we're checking
2605 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2606 MKDIR_P instead of AC_SUBST.
2607 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2608 Special magic for MKDIR_P, too.
2609 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2611 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2613 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2615 Sync from Automake, as follows:
2617 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2618 * config/install-sh: Initialize IFS, so field splitting isn't
2620 * config/mkinstalldirs: Likewise.
2621 * config/missing: Remove superfluous quotes. Replace all uses of
2622 `[' by `test', for consistency, and for..
2623 * config/missing (sed_minuso, sed_output): New variables.
2624 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2625 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2626 Fixes `missing' to detect `--output' for help2man. Fixes
2627 PR automake/483. Report by Dennis J. Linse.
2628 (autom4te): Document in `missing --help'.
2630 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2632 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2633 * config/install-sh: Don't use 'path' to talk about file names,
2634 as per GNU coding standards. Close a race condition reported by Ralf
2635 Wildenhues and Stepan Kasal. There is still a race condition
2636 on hosts that predate Posix 1003.1-1992, but we can't help this.
2637 Don't mishandle weird characters like space on pre-Posix hosts.
2638 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2639 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2640 AC_PROG_MKDIR_P from AS_MKDIR_P.
2641 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2642 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2643 earlier editions are not (including Automake 1.8.3).
2644 Do not suggest mkinstalldirs for thread-safety.
2645 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2646 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2647 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2648 presence of special characters and race conditions.
2649 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2650 in Autoconf's name space.
2652 2006-05-10 Bruno Haible <bruno@clisp.org>
2653 and Paul Eggert <eggert@cs.ucla.edu>
2655 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2656 from Automake with minor changes.
2657 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2659 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2661 * config/install-sh: Update to Automake CVS version, as follows:
2662 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2663 * lib/install-sh: Simplify the expr implementation of dirname.
2664 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2665 * lib/install-sh: Handle --, and diagnose unknown options.
2667 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2669 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2670 `./autom4te' to create `./testsuite', since the `all' target
2671 will ensure its presence, but `installcheck' should not create
2672 the uninstalled wrappers.
2674 * tests/torture.at (Unusual Automake input files): Skip if we
2675 detect automake < 1.8.
2677 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2679 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2680 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2681 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2684 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2686 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2687 munge (multiple) white space and other oddities.
2688 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2689 single quotes in variable assignment.
2690 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2691 and similar failures by adding multiple spaces, tabs, and other
2693 Report and different test suggested by Francesco Romani
2694 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2696 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2697 single quotes, we only need to search for single quotes; this
2698 both simplifies the search pattern, and makes us less
2699 susceptible to `echo' variations for arguments not containing
2701 (_AC_ARG_VAR_VALIDATE): Likewise.
2703 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2705 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2706 `$*' and IFS concatenation issue with traditional shells and
2707 bash-2.04. Report by Seanster@Seanster.com.
2709 2006-05-03 Bruno Haible <bruno@clisp.org>
2711 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2712 precisely which Mac OS X versions have the od problem.
2714 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2716 * doc/autoconf.texi: Use @option systematically.
2718 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2719 and Bruno Haible <bruno@clisp.org>
2721 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2723 (Integer Overflow): Mention the special case of integer division
2726 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2728 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2729 traditional shells like the Solaris one that do not use the
2730 first IFS character for assembling `$*'.
2731 Prompted by a related report from autoconf_bug@nro.ca.
2733 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2734 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2736 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2737 Mention more problems with the -e option.
2739 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2742 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2744 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2745 in URLs to improve DVI formatted output (requires texinfo 4.6).
2746 (System Services, Systemology, Shellology): Likewise.
2747 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2750 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2752 (Runtime): Fix macro argument names to match description:
2753 `action-if-found' -> `action-if-true' and similarly.
2754 (Obsolete Macros): Likewise.
2755 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2756 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2757 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2759 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2761 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2764 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2767 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2769 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2770 /bin/sh set unsorted output.

2779 (Writing Test Programs): Fix some langauge. Recommend exiting
2780 with status 1, not merely nonzero. Clarify exit declaration.

2789 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2791 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2792 since as_me isn't set yet.
2794 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2796 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2797 a few minor bugs in this area.
2799 * doc/autoconf.texi (Programming in M4sh): Comment out the
2800 documentation of AS_BASENAME, for now.
2801 (Shell Substitutions): Do not use AS_DIRNAME in an example.

2812 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2813 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2814 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2815 (_AS_DIRNAME_PREPARE): Likewise.
2816 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2817 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2818 (AS_DIRNAME): Use "dirname --".
2820 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2822 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2823 of "run time" and "run-time" changed to "runtime", for consistency.
2824 * lib/autoconf/fortran.m4: Likewise (in comment).
2825 * lib/autoconf/functions.m4: Likewise.
2826 * lib/autoconf/general.m4: Likewise.
2827 * lib/autoconf/headers.m4: Likewise.
2829 * doc/autoconf.texi (Run Time): Document the exit status situation
2830 with more accuracy and detail.
2832 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2834 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2835 Archive is not officially `GNU' any more. Update URL.
2836 (Defining Directories): Likewise
2837 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2839 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2841 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2842 newline from the `trap' code to finish `config.log'; the NetBSD
2843 /bin/sh resets the exit status after an empty command, as
2844 documented in doc/autoconf.texi.
2845 Reported by Dalibor Topic <robilad@kaffe.org>.
2847 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2849 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2850 Suggested by Bruno Haible.
2852 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2854 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2855 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2856 Instead, just list the shells that we know work.
2857 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2858 changed. Be more cautious about the _cv_ variable.
2859 * tests/tools.at (Syntax of the shell scripts): Check the
2860 _cv_ variable once, at first, to avoid an internal autoconf error
2861 when sh -n does not work.
2863 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2865 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2867 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2869 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2870 use ">&-" since we're only 99.999% sure that this is portable,
2871 and since the MinGW bug is fixed in a different way.
2872 * lib/autotest/general.m4 (AT_INIT): Likewise.
2874 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2876 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2877 before opening config.log, to avoid hitting a bug on MinGW.
2879 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2881 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2882 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2883 This works around a MinGW bug reported by Eric Paire.
2884 Make sure that all writes to the log file append to it,
2885 rather than possibly losing data.
2886 * lib/autotest/general.m4 (AT_INIT): Likewise.
2888 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2890 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2893 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2897 * configure.ac (AC_INIT): Bump to 2.59d.
2899 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2903 * Makefile.maint (news-date-check): Do not require a leading `*'
2904 before the release date in NEWS.
2906 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2907 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2909 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2910 the instantiated file do not contain the string 'datarootdir'
2911 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2912 @mandir@, replace the reference '${datarootdir}' by the value.
2913 * tests/torture.at (datarootdir workaround): New test.
2914 * NEWS: Advertise this temporary fixup.
2915 Based on a patch by Bruno Haible, reported and analyzed by
2916 Paul Eggert and Noah Misch.
2918 2006-04-12 Eric Blake <ebb9@byu.net>
2920 * tests/autotest.at (Debugging a failed test): Fix comment.
2922 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2924 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2925 all the changes since 2006-04-07.
2927 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2929 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2930 succeeded, but `ln -s file dir' failed, take care to remove the
2931 leftover target before the next test, to prevent its spurious
2932 failure; also make sure `ln file dir' works before selecting it.
2933 Thanks to Keith Marshall for pointing this out.
2936 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2937 assignments in `at_debug_args', so that we put them correctly
2938 in the `run' script.
2939 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2940 Reported by Eric Blake.
2942 2006-04-11 Eric Blake <ebb9@byu.net>
2944 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2945 top-level tests after micro-suite has been run. Used in...
2946 (Debugging a successful test, Debugging script and environment),
2947 (Debugging a failed test): ...these new tests. The first of these
2949 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2950 macro, split out from...
2951 (AT_INIT): ...here, so that using -d also generates a run script.
2952 Document that -d inhibits top-level logging.
2953 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2954 inhibits top-level logging; debug scripts are created.
2956 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2958 * tests/autotest.at (Empty test, Empty check): New test to check it.
2960 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2963 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2965 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2966 the files if a problem appears. Make the empty *.at files
2967 read-only, too. Proposed by Ralf Wildenhues.
2969 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2971 * config/Makefile.am: Add comment to force updated Makefile.in.
2973 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2974 space only patch to this file, this patch causes the Makefile.in
2975 files that include freeze.mk to be updated, and thus have a
2976 newer time stamp again, which in turn makes a pristine CVS
2977 checkout have correct time stamps.
2979 * Makefile.maint (cvs-sv): New macro, to be used..
2980 (config.guess-url_prefix, config.sub-url_prefix)
2981 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2982 point to CVS text checkout of Gnulib files.
2983 (copyright-check): Bump current year.
2984 (announcement): Do not hard-wire `./announce-gen'.
2985 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2987 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2989 (wget_files): Update config.guess, config.sub, texinfo.tex by
2990 `wget-update', now that their URLs work again.
2992 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2994 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2995 Problem noted by Paul D. Smith.
2997 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2999 * doc/autoconf.texi: Remove unused words from word list.
3000 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3001 .x-sc_trailing_space: New files.
3003 * doc/standards.texi: Sync from gnulib.
3005 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3006 `LIBOBJDIR' as experimental.
3008 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3009 with a target directory; it's internally implemented as `cp'
3010 anyway, but since Autoconf advertises the possibility to use
3011 a target directory when LN_S is `ln -s', we need to find out.
3012 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3013 analyzed by Keith Marshall <keith.marshall@total.com>.
3017 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3019 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3020 confdefs.h as-is. In general, if it has backslash-newline or the
3021 like, then it doesn't work either to sort or to remove empty
3024 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3026 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3028 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3030 * lib/autom4te.in (Automake-preselections): Preselect
3033 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3035 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3036 apostrophe within a single-quoted string, as this is the usual
3037 tradition and is easier to read than '"'"'. Don't rely on the
3038 shell treating "$/" like '$/'. Use a more-consistent indenting
3041 2006-04-09 Eric Blake <ebb9@byu.net>
3043 * tests/autotest.at (Backquote command substitution),
3044 (Multiline backquote command substitution): Remove mistaken
3045 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3047 (Parenthetical command substitution, Multiline parenthetical
3048 command substitution): here.
3050 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

3083 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3084 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3085 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3086 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3087 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3088 (Coding Style). Don't mention m4_expand_once.

3109 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
3110 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
3112 2006-04-08 Stepan Kasal <kasal@ucw.cz>
3114 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
3115 of the warning introduced by the 2001-08-28 change.
3117 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
3118 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3120 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
3121 variables shall be overriden by the cache.

3125 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3127 Revert the patch from 2006-04-01 and only improve
3128 _AS_DETECT_BETTER_SHELL:
3130 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3131 skip nonexistent directories.
3132 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3133 only shell candidates which exist.
3134 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3135 * lib/autotest/general.m4 (AT_INIT): No need to give three
3136 parameters to _AS_PATH_WALK.
3138 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3139 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3141 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3142 distinguish m4sugar macros.
3143 * tests/tools.at (autoupdating with aclocal and m4_include):
3144 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3145 test case by Noah Misch <noah@cs.caltech.edu>.

3158 * doc/autoconf.texi (Programming in M4sh): Document that
3159 AS_MKDIR_P exits the script on failure.
3160 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3162 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3164 * config/elisp-comp, config/install-sh, config/mdate-sh,

3181 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3183 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3184 whether `set' quotes correctly: redirect stderr of the tested
3185 `set', and use a subshell, for Ultrix; use `sed' instead of
3186 `grep' for zsh `set' which may write binary output; match only
3187 at the beginning of a line, to avoid false positives.
3188 In order to avoid false positives by unrelated variables with
3189 multiline content, put the dump algorithm in a subshell and
3190 unset all variables containing newlines (except some which are
3191 special to the shell). Warn about cache variables that are
3194 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3196 * config/config.guess, config/config.sub, config/texinfo.tex:
3199 * tests/mktests.sh: Reword comments.

3205 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3206 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3207 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3208 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3210 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3211 shell issue with double-quoted command substitutions of native
3213 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
3216 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

3231 2006-04-06 Stepan Kasal <kasal@ucw.cz>
3233 * tests/Makefile.am (maintainer-check-posix):
3234 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
3236 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
3237 ac_config_<foo>s again, sometimes normalized, sometimes not.
3238 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3239 (AC_CONFIG_COMMANDS): Do not do so here.
3240 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3241 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3242 2005-07-25 rewrite. Noticed by Noah Misch.
3244 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3245 _AC_PRESERVE_HELP_ORDER, ...
3246 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3248 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3249 inside m4_expand_once; it is redundant.

3252 for --help from Cygnus `configure.'
3254 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

3265 Noah Misch <noah@cs.caltech.edu>
3267 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3268 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.

4215 2005-09-27 Stepan Kasal <kasal@ucw.cz>
4217 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
4218 in case the computer is too quick. Double quote the configure.ac
4221 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
4222 problems if the testsuite were running too fast.
4224 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4226 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4227 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4228 (which belong to Xt, not X itself). See Debian bug 327655.
4229 * NEWS: Mention this.
4231 2005-09-07 Stepan Kasal <kasal@ucw.cz>
4233 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
4235 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
4237 * config/move-if-change: Don't output "$2 is unchanged";
4238 suggested by Ben Elliston. Handle weird characters correctly.
4240 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4242 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4243 calls, so that the final expansion of this macro is shorter.
4244 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4245 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4246 the cleanup there. Use AS_VAR_* macros, to be more general.
4247 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4249 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4251 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
4253 2005-09-01 Stepan Kasal <kasal@ucw.cz>
4255 * doc/autoconf.texi (Configuration Headers): Add an index entry
4258 2005-08-26 Pavel Roskin <proski@gnu.org>
4260 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
4261 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
4264 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4266 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4267 The previous patch didn't work, so try a better one.
4269 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4271 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4272 in the example. Reported by Bruno Haible.
4273 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4274 "if $undefined_var;" succeeds with my shell.
4276 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4277 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4278 but change the m4_divert_text to m4_divert_once.
4280 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4282 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4283 Work around bug in Solaris /usr/xpg4/bin/awk.
4284 The bug is present in at least Solaris 8 through 10.
4286 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4288 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4289 some evil values and relying on the fact that $* concatenates the
4290 parameters by the first character from IFS.
4292 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4293 Stepan Kasal <kasal@ucw.cz>
4295 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4296 first header appears, define AH_HEADER.
4297 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4298 Update limitations about when to call AC_CONFIG_HEADERS.
4299 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4300 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4301 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4302 ``Configuration Actions''; fix their index entries.
4304 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4305 options correctly. Process N-M as M-N if M is smaller than N.
4306 Process ranges correctly so that N-N will run only N.
4307 Sort and uniquify the tests that will be run. If there is more
4308 than one test, reinsert the banners for the tests.
4309 * tests/autotest.at (Keywords): Unmark XFAIL.
4311 2005-08-23 Stepan Kasal <kasal@ucw.cz>
4313 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4314 before passing the macro name to AH_TEMPLATE.
4316 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4317 now opens log after option processing; in particular, --version
4318 and --help do not touch config.log.
4320 * Makefile.maint: Revert the change from 2005-08-12.
4322 2005-08-22 Stepan Kasal <kasal@ucw.cz>
4324 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
4326 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
4328 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4330 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4331 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4334 * doc/autoconf.texi (Defining Symbols, Changed Results):
4335 Prepend to LIBS, not append, in examples.
4337 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4339 When building in place, set srcdir="."; suggested by Tim Van Holder.
4341 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4342 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4343 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4344 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4345 does not mean "no --srcdir option".
4347 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4349 * tests/autoscan.at (autoscan): New file.
4350 * tests/suite.at: Use it.
4351 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4352 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
4354 * tests/autotest.at (Keywords): Test keywords combinations.
4356 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4358 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4359 add "2>&1"; gzip 1.2.4 prints help on stderr.
4361 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4363 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4364 was pushdef'ed twice while popped only once. Push it only once.
4365 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4367 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4369 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
4370 prefixed by mere "===", not "configure: === ".
4372 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
4374 * Makefile.maint: Update from Bison.
4376 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4377 "<tab>" in comment, so that the point is understandable.
4379 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4381 Rewrite substantial part of lib/autoconf/status.m4.
4382 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4383 and CONFIG_COMMANDS are not processed in four separate loops.
4384 Instead, there is one main loop. This alows that the common code
4385 is expanded only once, thus config.status (and configure) is smaller.
4387 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4388 the AC_LIST_FILES and cousins macros are no longer used.
4390 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4391 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4392 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4393 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4394 contain the initialization, nor the for loop, nor the associated
4395 commands; all these go to ...
4396 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4397 _AC_OUTPUT_CONFIG_STATUS.
4398 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4399 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4400 (_AC_OUTPUT_FILE): The creation of the sed script ...
4401 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4402 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4403 _AC_OUTPUT_MAIN_LOOP.
4404 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4405 _AC_CONFIG_COMMANDS): Use ...
4406 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4407 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4408 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4409 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4410 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4411 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4413 (_AC_CONFIG_UNIQUE): Update.
4414 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4415 Replaced by this ...
4416 (_AC_LIST_TAGS): ... new common macro.
4417 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4418 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4419 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4420 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4421 this didn't belong to the `config commands' section.
4422 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4423 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4424 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4425 to the `config commands' section either.
4426 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4427 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4429 ... and many changes to the comments nearby.
4431 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4432 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4433 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4434 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4435 (#define header templates): The comment at the top of the generated
4436 header now includes the name(s) of the source file(s).
4438 Several unrelated small changes:
4440 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4441 parameter to AC_DIAGNOSE.
4442 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4443 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4444 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4445 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4447 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4448 in AC_OUTPUT doesn't double-quote it either.
4449 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4452 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4454 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4455 versions of Portland Group compiler produce single- and double-quoted
4456 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4457 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4459 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4461 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4462 This is a corrected version of yesterday's patch.
4464 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4466 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4467 path, too; insert a "===" to emphasize the line.
4469 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4470 ac_cv_build_alias to ac_build_alias.
4471 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4473 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4474 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4475 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4476 (AC_ARG_VAR): ... here.
4477 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4480 Keep a list of all precious variables and process them with one simple
4481 for loop, instead of expanding all commands, or, OTOH, complicated
4482 processing of output of "set".
4483 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4484 variable names in new macro...
4485 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4486 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4487 a loop to assign all ac_env_* and ac_cv_env_* variables.
4488 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4490 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4491 its value to shell variable ac_precious_vars and call
4492 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4493 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4494 _AC_ARG_VAR_VALIDATE.
4496 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4497 and the AC_SUBSTs ...
4498 (AC_INIT): ... here.
4500 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4501 the ac_subst_files section in config.log.
4503 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
4505 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
4507 * NEWS: New macro AC_C_TYPEOF.
4508 * doc/autoconf.texi (C Compiler): Document AC_C_TYPEOF.
4509 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.

4512 Fix problems reported by Nicolas Joly.
4513 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
4514 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4515 They are generated by the Tru64 v5.1B shell.
4517 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4519 Fix my changes from 2005-07-01; reported by Noah Misch.
4520 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4521 description, the macro now accepts only a single tag.
4522 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4524 Fix cases when the varsions of Autoconf and Autotest don't match.
4525 Reported by Noah Misch.
4526 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4527 at_top_builddir, for compatibility with older autotest.
4528 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4529 is not set, use at_top_builddir, for compatibility with older
4530 versions of autoconf.
4532 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4534 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4535 Problem reported by Patrick Welche.
4537 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4539 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4540 sed substitution command, so that we allow | in program prefixes
4541 and program suffixes. (& is a problem anyway; we're not fixing
4543 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4544 configure_input, top_builddir, srcdir, etc.
4545 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4546 PATH_SEPARATOR in AUTOTEST_PATH.
4548 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4550 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4551 for loop over config.site files using `set', to allow
4552 directory names containing IFS characters.
4554 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4556 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4557 directories with weird names. Apparently some people like living
4558 on the edge. However, improve the test that "pwd" actually does
4559 report a name for the working directory.
4560 * NEWS: Remove the claim that we test for funny chars in dir names.
4562 2005-07-01 Stepan Kasal <kasal@ucw.cz>

4578 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4579 document to output the default config_* lists to config.status.
4580 Don't recognize option --file, if the functionality is not there.
4581 Likewise for --header; moreover, recognize --he and --h as shortcuts
4582 for --help in that case.
4584 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4585 matches the order of execution. No code changed.
4587 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4589 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

4606 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
4607 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4608 (AC_SUBST): Call it.
4609 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4610 the directory specific variables; but don't call it for configure_input.
4612 2005-06-28 Derek Price <derek@ximbiot.com>
4614 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4617 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4619 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4620 directory have inherent problems with special characters like spaces,
4621 due to limitations in Make syntax. Problem reported by Alexandre
4623 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
4624 Also, fix Tru64 porting problem with shell patterns,
4625 reported by Ralf Wildenhues.

4635 Fix some more shell quoting problems. Prompted by a bug report
4636 from Justace Clutter.
4637 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4638 variable into diagnostic. Make the diagnostic an error, not a warning,
4639 because we really don't support spaces and suchlike in dir names.
4640 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4641 Don't worry about backslashes in srcdir; it can't happen now.
4642 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4643 Simplify ac_optarg handling.
4644 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.
4646 2005-06-22 Stepan Kasal <kasal@ucw.cz>

4652 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4654 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4655 that '\|' is not allowed in BREs; recommend using newline separated
4656 list of patterns instead of multiple -e options.
4658 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4660 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4666 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4668 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4669 b, t, r, w commands require single space, while : cannot have any.
4670 (Special Shell Variables): Fix sed code this in the example.
4671 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4672 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4674 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

4680 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4682 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4684 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4685 * doc/autoconf.texi:
4686 Don't mention Solaris versions so much, if a
4687 problem is common to all extant versions of Solaris. Say "SunOS
4688 4" instead of "SunOS" for SunOS 4.
4689 (awk): Mention more of the limitations of traditional Awk.
4690 (cat): Don't talk about cat -v.

4694 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4695 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
4696 but the implementation is entirely different and is designed
4697 to be compatible with glibc strverscmp.
4698 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4700 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4701 on Mac OS X 10.4 reported by Peter O'Gorman in:
4702 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4703 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):

4706 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4708 * doc/autoconf.texi: "filesystem" -> "file system".
4709 "behaviour" -> "behavior".

4711 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4713 * lib/m4sugar/m4sh.m4: Likewise.
4714 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4715 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4717 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4718 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4719 to update the man page. That way, we don't have to check in new
4720 man pages every month.
4722 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4723 quotes and backslashes. Patch from Derek Price.

4732 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4733 -u, since it outputs chatter if the input files are the same.
4734 Problem reported by Ralf Menzel.
4736 2005-06-08 Derek Price <derek@ximbiot.com>
4738 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4739 renaming them since they are about to be redefined anyhow.
4741 2005-06-08 Derek Price <derek@ximbiot.com>
4743 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4744 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4745 Move m4_undefine to alphabetical order.
4747 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4749 * README: Recommend GNU M4 1.4.3 or later.
4750 * doc/autoconf.texi (Introduction): Likewise.
4751 Reword to avoid some formatting glitches.
4752 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4753 Clarify explanation of HP compiler bug.
4754 Redo example output tp match current CVS snapshot.
4755 Use @example.org in email addresses when the examples
4756 might get inadvertently cut-and-pasted into user code.
4757 Remove example of autom4te usage that doesn't seem to work now.
4758 Use modern AC_INIT (except when the example is meant to be
4759 shown with Autoconf 2.13).
4760 Update ksh info for Solaris 9 and later.
4762 Modernize description of Automake versions a bit.
4763 Don't claim a future version of Autoconf is near.

4769 follows its own advice about quoting better.
4770 Reword to avoid some formatting glitches.
4771 * doc/installt.exi: Reword to avoid some formatting glitches.
4773 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4774 Tru64 ksh pattern matching bug. Reported against Libtool by
4775 Albert Chin <libtool@mlists.thewrittenword.com> and
4776 Nicolas Joly <njoly@pasteur.fr>.
4778 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4780 m4_cdr of one-member list was [[]] (one-member list containing an
4781 empty string) instead of [] (an empty list. Callers were skewed to
4782 match this misbehaviour. As a consequence of this:
4783 - m4_foreach([x], [], [foo]) expanded to `foo', while
4784 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4785 This bug has been fixed:
4787 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4788 expand to an empty string; print error msg if called without
4790 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4791 misbehaviour; handle [] and [[]] correctly.
4793 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4795 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
4796 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
4797 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4799 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4801 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4802 swallow records with more than 99 fields.
4803 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4804 parse the long line.
4806 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4808 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4809 swallow literals longer than 399. Reported by Ralf Wildenhues.
4810 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4811 to workaround this limitation.
4813 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4815 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4816 to gfortran, and make these the first two compiler names
4817 checked (following the general autoconf preference for gcc).
4819 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4821 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4822 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4823 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4825 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4827 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4828 expression of unbounded size when processing the --list
4829 option. This runs afoul of a limit of 399 bytes per regular
4830 expression on AIX. Problem reported by Ralf Wildenhues.
4832 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

4835 * doc/autoconf.texi (Particular Headers): Reword example
4836 for multiline stdbool replacement.
4837 (Setting Output Variables): Reword text a bit. Don't
4838 give all the details about |#_!!_#|.
4839 Reword description of line replacement.
4841 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4843 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4844 now contain newlines, and substituted files must be referenced on
4845 a line alone; the sed scripts to substitute them are now very
4847 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4848 commands can be put in a sed script portably.
4849 * doc/autoconf.texi (Setting Output Variables): Document above
4850 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4851 use of multiline substitution.

4861 * tests/local.at: Don't attempt to check for negated character
4862 classes in shell scripts. The test was too brittle.
4864 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4866 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4867 * doc/autoconf.texi (Limitations of Builtins): Document this
4870 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4872 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4873 common code; used in many places in the tree.
4874 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4875 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4877 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4879 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4880 messages when ac_unique_file is not found.
4881 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4882 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4883 commands, for consistency with AC_MSG_ERROR and such.
4885 * bin/autoconf.as: Make more use of "shift 2" in option processing.

4895 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4897 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4898 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4899 (ac_top_builddir): ... this ...
4900 (ac_top_build_prefix): ... to this; the old name is also kept, for
4901 backward compatibility.
4902 (ac_top_builddir_sub): New variable, without the trailing slash,
4904 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4905 * doc/autoconf.texi (Configuration Actions): Rename
4906 ac_top_builddir to ac_top_build_prefix.

4918 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4919 argument to m4_foreach. I guess it was necessary in the past,
4920 but I think it's a no-op now.
4922 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4924 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4925 ``cat <<_ACEOF'' commands to one.

4931 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4933 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

5004 quoting rules. Problems noted by Stepan Kasal.
5005 Also, throughout this document, be more careful about white space.
5006 "blank", "white space", and "space" all have different meanings
5007 and we should be careful to say what we mean.

5058 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5059 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5060 comment and reduce m4_default([foo], []) to [foo].
5061 (m4_strip): Update the explanation.
5063 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5065 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5066 Remove core.conftest.* too; it's generated by Tru64 5.1.
5067 Problem reported by Jennis Pruett.
5068 * lib/autoconf/functions.m4
5069 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5070 Don't bother to remove core files; AC_RUN_IFELSE should do that

5075 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

5126 a directory whose name contains a special character like space,
5128 * doc/autoconf.texi (Installation Directory Variables): Allow

5141 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5142 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5143 ac_pwd, and quote srcdir.
5144 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5146 * doc/autoconf.texi: Fix some systematic formatting problems.
5147 ".)" needs a following @: if not at the end of a sentence, and
5148 similarly for "!)". "etc." should be preceded by a comma.
5149 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5151 2005-03-22 Bruno Haible <bruno@clisp.org>
5153 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5154 argument is often called 'build-aux'.
5156 2005-03-07 Stepan Kasal <kasal@ucw.cz>

5163 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5165 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5166 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5167 from a Common Lisp's `cl'.
5168 (AC_PROG_CXX): Behave according to the documentation: don't
5169 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5170 make the variable CCC precious; use `cl.exe', not `cl'.

5173 Alexandre Duret-Lutz <adl@gnu.org>
5175 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5176 /dev/null, as "configure" shouldn't read stdin, and this insulates
5177 us from problems (e.g., when testing for "cl"). Also, do this
5178 redirection before invoking "hostname" or "uname", and keep the
5179 original input stream available via...
5180 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5181 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

5193 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5194 newline if neither \c nor -n work, as that would output two
5195 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5197 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5199 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5200 This causes that any required macros inside will get before the if.
5201 * doc/autoconf.texi (autom4te.cache): A typo.
5203 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5205 Undo previous change, except keep the change to
5206 lib/autoconf/programs.m4 that replaced grep with shell
5207 pattern-matching. This is because net-snmp configure reads stdin.
5208 Reported by Noah Misch.
5210 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5212 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5213 from /dev/null, as "configure" shouldn't read stdin, and this
5214 insulates us from problems (e.g., when testing for "cl").
5215 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5216 before invoking "hostname" or "uname".
5217 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5218 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5219 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5220 "</dev/null" since it's now done at the top of 'configure'.
5221 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5222 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5223 Also, replace grep with shell pattern-matching, to save a process.

5227 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5228 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5229 avoid thinking that Allegro Common Lisp's "cl" command is a C++

5246 Fix some @code's that should have been @env's, and vice versa.
5247 Sort environment variable names.
5248 Mention that shells no longer inherit IFS.
5249 Don't recommend PATH_SEPARATOR=';' so strongly.
5250 Mention that $RANDOM might expand to the empty string.

5328 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

5331 2047-byte limit on line length of portable text files.
5332 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5333 Use newline as a separator, not space.

5391 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5392 Update the long comment explaining it.
5394 m4_require no longer writes an ``is required by'' line to the
5395 execution stack. It contains only one bit of non-redundant
5396 information: that the macro was required, not called. And even
5397 this bit is useless in most situations: have you ever met a macro
5398 which both calls and requires the same macro?
5400 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5401 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5404 (m4_expansion_stack_pop): Remove the misplaced comment.

5406 execution stack; slightly improve the out-of-a-defun error message.
5407 (_m4_divert_grow): New macro, counter for the temporary diversions.
5408 (_m4_require_call): Use it.
5409 * tests/m4sugar.at (m4_require): Expect output without the
5410 ``is required by'' messages.
5412 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

5448 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5449 Warn about newline stripping in `` and $(). Update Solaris
5451 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5452 X insulates us from future changes to Posix.
5453 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
5456 2005-01-19 Stepan Kasal <kasal@ucw.cz>

5501 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
5502 (_m4_divert_n_stack): New macro; the expansion is
5503 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
5505 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5506 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5507 stored in _m4_divert_diversion or _m4_divert_dump.
5508 (m4_divert_pop): When the parameter is given, compare the symbolic
5509 name with the last diversion pushed on the stack. Previously, the
5510 current diversion was compared with the numeric value of the
5511 diversion given as the parameter.
5512 (m4_require): If the macro hasn't been expanded yet, call ...
5513 (_m4_require_call): this new macro.

6054 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6056 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6058 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6059 Document problem with "`""`" in pdksh POSIX mode.
6061 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6063 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6064 with pdksh, too. Problem reported by Patrick Welche via
6066 * doc/autoconf.texi (Shellology): Note that set -o posix is
6067 useful for pkdsh, too.
6069 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6071 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6072 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6073 Don't fail if ENV or BASH_ENV is readonly.
6074 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6075 etc. are read only. Problem reported by Ludovic Courtes.
6077 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6079 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6080 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6083 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6085 * doc/autoconf.texi (File System Conventions): Warn about
6086 names like "aux". Problem reported by Eric Blake.
6088 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6089 by zero instead of array size, so that we can use any arithmetic
6090 constant expression (instead of requiring an integer constant
6091 expression). This allows us to test expressions like DBL_MAX <
6092 LDBL_MAX, which didn't conform to the C standard using the old
6094 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6095 now that we can do floating-point tests at compile time.
6097 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6099 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6100 and LDBL_EPSILON, as the resulting expression isn't an
6101 integer constant expression and violates the C standard.
6102 Problem reported by Nelson H. F. Beebe. Also, check
6103 for "L" suffix, and check that long double doesn't have
6104 worse range or precision than double, that mixed-mode
6105 arithmetic doesn't generate a diagnostic, that double
6106 constants fit in long double.
6108 2004-06-03 Kevin Ryde <user42@zip.com.au>
6110 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6111 malloc(0) and realloc(NULL,size).
6113 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6116 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6118 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6119 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6122 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6124 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6125 can be rewritten using if-then-else. Suggested by Bruno Haible.
6127 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6129 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6130 Problem reported by Stepan Kasal.
6132 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6134 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6135 change). Patch reported by Ralf Wildenhues in
6136 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6138 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6139 function F exists if the compiler and linker let you compile an
6140 expression like (F != 0). Recent versions of GCC optimize away
6141 the reference to F in that case, since every function address must
6142 be nonzero, so the link succeeds even if F does not exist.
6143 Problem reported by Manu in
6144 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6146 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6147 "Unix". Many uses changed.
6148 (Limitations of Builtins): Explain better why the ! command isn't
6151 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6153 * lib/autom4te.in (Automake-preselections): Preselect
6154 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6156 2004-05-19 Kevin Ryde <user42@zip.com.au>
6158 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6159 referencing AC_FUNC_STRERROR_R.
6161 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6162 note pessimistic assumption when cross compiling.
6164 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6166 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6167 (until 2004) invoked subcommands with sh -e, contra POSIX.
6168 Reported by Kevin Ryde.
6170 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6172 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6173 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6174 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6175 `test -f " /usr/bin/grep"', which _always_ failed.
6176 (AC_PROG_SED): Ditto bogus PATH fix.
6177 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6178 requires that grep correctly supports _multiple_ `-e' options, rather
6179 than stating only that grep should accept `-e'.
6181 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6183 Port to C99, which requires that 'exit' be declared.
6185 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6186 to ensure that stdlib.h is included.
6187 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6188 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6189 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6190 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6191 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6192 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6193 when using 'exit' in a test; C99 requires that 'exit' be declared.
6195 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6197 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6198 now prefers 'grep' implementations that accept -e.
6199 (Limitations of Usual Tools): Describe problems of traditional
6200 egrep and fgrep with long input lines, and of traditional grep
6202 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6203 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6204 All callers changed. Append /usr/xpg4/bin to the PATH, for
6206 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6207 the user with complaints about multiple -e options.
6208 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6209 Define it with AC_PROG_GREP.
6210 * configure.ac (AC_PROG_GREP): Add.
6211 * lib/freeze.mk (GREP): New macro.
6213 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6215 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6216 a possible candidate only after all others fail, rather than
6217 consulting it first. This improves backward compatibility by
6218 better reflecting the way shell selection occurred in previous
6219 versions of Autoconf, and should help to avoid triggering latent
6220 problems in other packages, such as the one in Automake where zsh
6221 is not handled robustly:
6222 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6223 Although it is not Autoconf's responsibility to work around
6224 problems in Automake, it nevertheless makes sense to avoid
6225 introducing unnecessary incompatibilites.
6227 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6228 Gary V. Vaughan <gary@gnu.org>
6230 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6231 how deeply nested we are when a suitable tool is found, set the
6232 ac_path_TOOL_found flag.
6233 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6234 nested we are in this macro. Break out of all 3 nested loops if
6235 ac_path_TOOL_found is set.
6237 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6239 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6240 of the _AS_PATH_WALK loop too if GNU flavor is found.
6242 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6244 * doc/autoconf.texi (Limitations of Make): Update documentation
6245 for `$<'. New entry `Long lines', based on a report from Simon
6246 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6247 paragraph about DJGPP, based on a mail from Richard Dawe.
6249 2004-04-20 Paul Eggert <eggert@twinsun.com>
6251 * tests/c.at (C keywords): Don't assume that GCC supports
6252 "restrict" and "inline", as sufficiently-old GCC versions do not
6253 (also, GCC configured to be in pedantic C89 mode does not).
6254 Problem reported by Sumit Pandya in:
6255 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6257 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6258 consider -g to work if it generates warnings when plain compiles
6259 don't. Problem reported by Braden McDaniel in:
6260 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6262 * doc/autoconf.texi (Slashes): New section, to document a problem
6263 reported by Jim Meyering in:
6264 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6266 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6267 linker output files before linking, to work around IRIX 6 linker bug.
6268 Problem reported by Rainer Orth in:
6269 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6271 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6273 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6274 best tool so far counter rely on the tool path variable name to
6275 avoid checks for one tool being affected by the results of running
6276 the length check on a previous tool.
6278 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6279 match expression argument, as different greps have different
6280 regular expression flavours.
6281 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6283 (AC_PROG_EGREP): Pass 'EGREP$'.
6284 (AC_PROG_GREP): Pass 'GREP$'.
6286 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6288 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6289 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6291 2004-03-29 Paul Eggert <eggert@twinsun.com>
6293 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6294 Types, Specific Compiler Characteristics, System Services,
6295 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6296 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6297 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6298 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6300 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

6313 HAVE_STRUCT_TM_TM_ZONE is not defined.
6314 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6315 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

6326 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6327 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6328 H. F. Beebe for the bug report.

6384 * bin/Makefile.am (edit): Don't use $< in a context where
6385 POSIX doesn't require support for it. Use $@.in instead.
6386 Problem reported by Anthony N. Frasso in
6387 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

6419 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6420 Darwin uses -lcrt2.o and there's little point to cataloging all
6421 the system variants. Partial fix reported by Andreas Waechter in:

6511 egrep and fgrep respectively if $GREP -E/-F don't work.
6512 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6513 _AC_PROG_GREP, and AC_PROG_SED.
6514 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6515 longest input length accepted by a command.
6516 (AC_PROG_SED): Use it.
6517 * doc/autoconf.texi (Particular Programs): Document the changes.
6520 2004-01-27 Paul Eggert <eggert@twinsun.com>
6522 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
6523 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6524 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
6525 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
6527 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6528 bin/autoconf.in, config/Makefile.in, config/config.guess,
6529 config/config.sub, config/install-sh, config/mdate-sh,

6544 2004-01-26 Paul Eggert <eggert@twinsun.com>
6546 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6547 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6548 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6549 not <inttypes.h>. Problem reported by Tim Mooney in
6550 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6551 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6554 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6555 otherwise "make check" fails because it forbids cmp (I guess
6556 because cmp treats files as binary on DOS-like systems).
6558 * tests/mktests.sh: Update copyright date to 2004, since some tests
6559 have changed in 2004.
6561 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6563 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6564 non-truncating sed or gsed program in PATH.
6565 * tests/acprograms.at: Add it.
6566 * doc/autoconf.texi (Particular Programs): Document it.
6569 2004-01-15 Paul Eggert <eggert@twinsun.com>
6571 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6572 -std1 disables some useful extensions on Tru64. Problem reported
6574 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6576 2004-01-14 Paul Eggert <eggert@twinsun.com>
6578 * doc/autoconf.texi (Programming in M4sh): Document that
6579 AS_MKDIR_P succeeds if the destination is a symbolic link
6580 to an existing directory.
6581 (Limitations of Usual Tools): Note that mkdir -p might not
6582 succeed on symlinks to directories.
6584 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6586 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6587 * bin/autoheader.in: Grammar fix in message.
6588 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):

6591 2004-01-13 Eric Blake <ebb9@byu.net>
6593 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6594 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6596 2004-01-10 Jim Meyering <jim@meyering.net>
6598 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6600 2004-01-09 Paul Eggert <eggert@twinsun.com>
6602 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6603 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6604 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6605 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6606 AC_COMPILE_IFELSE, since we now assume our caller invokes
6607 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6608 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6609 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6610 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6612 2004-01-07 Paul Eggert <eggert@twinsun.com>
6614 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6615 `"'...'"`, as it's confusing (and I suspect it may not work on
6616 some platforms). The code was incorrect anyway, as it assumed
6617 that \$ evaluated to itself in that context. Reported by
6618 Alexandre Duret-Lutz.
6620 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6622 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6623 and _LT_AC_TAGCONFIG.
6625 2004-01-06 Paul Eggert <eggert@twinsun.com>
6627 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6628 example, and add more examples. Reported by Eric Sunshine.
6630 2004-01-05 Paul Eggert <eggert@twinsun.com>
6632 * doc/autoconf.texi (Limitations of Usual Tools):
6633 Remove warning against "rm -fr" introduced yesterday; it
6636 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6637 autoscan, autoupdate, ifnames): Don't use chmod -w.

6646 by doing lineno substitution only on lines containing "$LINENO".
6648 2004-01-04 Paul Eggert <eggert@twinsun.com>
6650 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6651 Use "rm -f" to remove conftest.sed, not plain "rm".
6652 Bug reported by David Relson in
6653 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6655 * Makefile.am (autom4te-update):
6656 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6657 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6658 * doc/autoconf.texi (Guidelines): Likewise.

6665 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6667 * doc/autoconf.texi (Limitations of Usual Tools):
6668 Warn against "rm -fr".
6670 2004-01-03 Paul Eggert <eggert@twinsun.com>
6672 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6673 -c -o might not work. From a suggestion by Kevin Ryde.
6674 (C Compiler, Generating Sources, Limitations
6675 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6676 Don't put '-o' after non-options, as POSIX doesn't allow this.
6677 Mention that cc's name might be gcc or c89 or whatever.
6679 2004-01-04 Kevin Ryde <user42@zip.com.au>
6681 * doc/autoconf.texi: Add various further index entries.
6683 2003-12-29 Paul Eggert <eggert@twinsun.com>
6685 * bin/autoreconf.in (autoreconf_current_directory):
6686 Fix typo: mkdir without umask arg.
6688 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6690 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6691 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6692 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6693 explanation clearer.
6695 2003-12-24 Andreas Schwab <schwab@suse.de>

6703 * configure: Regenerate.
6704 * tests/atlocal.in: Store the result here.
6705 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6706 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6707 of explicitly testing.

6709 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6710 * tests/tools.at (Syntax of the shell scripts): Simplify

6728 (AS_SHELL_SANITIZE): Move reinvocation code from
6729 _AS_LINENO_WORKS, use it to find out if shell
6731 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6733 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6734 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
6736 * lib/autotest/general.m4: Use AS_INIT_WITH_SHELL_FN.

6785 the expanded body, consistently with other macros such as AC_USG.
6787 2003-11-17 Paul Eggert <eggert@twinsun.com>
6789 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes

6821 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

7001 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
7003 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7004 cache variable instead of $G77 to decide whether to include -O2,
7005 since $G77 is specific to Fortran 77.
7007 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7009 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
7010 free" flag. Re-order flags tested into rough order of popularity.
7012 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7014 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7015 arguments so that it can be used with syntax identical to
7016 AC_PROG_F77, and so that we can more easily decide to
7017 remove/deprecate the DIALECT optional argument in the future if it
7019 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7020 non-freeform-supporting compilers. Document freeform flags.

7027 2003-10-03 Akim Demaille <akim@epita.fr>
7029 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
7030 * bin/autoreconf.in (autoreconf_current_directory): Create the
7031 AUX_DIR if needed, for sake of automake --add-missing etc.
7032 Suggested by Alexandre Duret-Lutz.

7036 * configure.ac: Quotation and formatting changes.

7083 Problem reported by Lars J. Aas in
7084 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
7085 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7086 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7087 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7089 2003-09-26 Akim Demaille <akim@epita.fr>
7091 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7092 directory for AC_CONFIG_COMMANDS' first argument exists.
7093 This makes valid the invocation of _AC_SRCPATH that follows.
7094 Reported by Eric Sunshine.
7095 * doc/autoconf.texi (Configuration Commands): Adjust.
7097 2003-09-26 Akim Demaille <akim@epita.fr>
7099 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7100 Reported by Ralf Corsepius.
7102 2003-09-26 Akim Demaille <akim@epita.fr>
7104 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the

7111 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
7112 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.

7118 The test suite are sometimes assigning timings incorrectly.
7119 Reported by Henk Krus.
7120 Diagnosed by Nicolas Joly.
7122 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7124 Instead of making AT_help a sequence of assignments to grow
7125 $at_help_all, just make AT_help_all be the growing contents of
7126 $at_help_all, and make a single assignment in...
7128 (at_times_skip): Flip the meaning and rename as...
7130 (AT_INIT): When summarizing the test that ran, remove
7131 $at_times_file after use, and check it is present before trying to
7134 2003-09-25 Akim Demaille <akim@epita.fr>
7138 * bin/Makefile.am (edit): Handle '@configure_input@'.
7139 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
7140 (ifnames): chmod -w.
7141 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7142 executables, not bin/ executables! Otherwise all the magic needed
7143 to find non installed files is turned off. This caused a failure
7144 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7145 as found in its environment (sent by tests/autoreconf): pointing
7146 to bin/autom4te that could not find its files.
7147 * tests/mktests.sh: Force the replacement of generated files, for
7148 the sake of "mv" program that are interactive when overwriting a
7150 * config/install-sh: Upgrade from CVS Automake.
7152 2003-09-23 Paul Eggert <eggert@twinsun.com>

7155 versus test -L issues.
7157 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
7158 Paul Eggert <eggert@twinsun.com>
7160 Trivial change to support GCC's configuration procedure.

7225 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
7226 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
7228 2003-09-04 Akim Demaille <akim@epita.fr>

7239 2003-09-04 Akim Demaille <akim@epita.fr>
7241 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7243 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7245 Add support for newer Fortran dialects. The F77 interface is
7246 unchanged, and continues to support Fortran 77. New FC macros
7247 correspond to all the old F77 macros, with output variables FC,
7248 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7249 available dialect, but older dialects can be specified. There are
7250 new macros AC_FC_SRCEXT to set the source extension, and
7251 AC_FC_FREEFORM to accept free-form source files.

7286 * tests/m4sugar.at (cross_warning): Make sure to enable the
7287 output, so that we can track spurious m4sugar output.
7288 * tests/local.at: Require 2.57.
7289 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7290 are defaulted by AT_CHECK anyway.
7291 Use AT_CHECK_AUTOM4TE.
7292 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a

7349 Replace the former...
7350 (m4_warn): Pass the call stack to _m4_warn.
7351 * bin/autom4te.in: Adjust to output the call stack.
7352 * tests/m4sugar.at (m4@&t@_warn): Adjust.
7354 2003-08-22 Akim Demaille <akim@epita.fr>

7369 2003-08-21 Akim Demaille <akim@epita.fr>
7371 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7373 ($help): Use Autom4te::ChannelDefs::usage.
7374 * bin/autoscan.in: Use Autom4te::ChannelDefs.

7377 2003-08-21 Akim Demaille <akim@epita.fr>
7379 First stab at preserving warnings between calls to autom4te,
7380 including when the cache is used.
7382 There are still several issues: (i) there are too many runs of m4
7383 (one for include, one for warnings, and some more), (ii) warnings
7384 spreading on several lines are not handled gracefully, (iii) the
7385 code meant to have the call stack display for errors does not work
7386 (its handling should move from m4 to autom4te).
7388 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7390 (@preselect): Add m4_warn.
7391 ($exit_status): Remove, use $exit_code.
7392 ($help): Use Autom4te::ChannelDefs::usage.
7393 (&handle_m4): No longer define the m4_warnings.
7394 At each run, extract and report the warnings.
7395 Always cache the result, including if the exit status is on
7396 failure, since if nothing changes, we should result in the same
7397 failure, hence we can use the cache.
7398 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7399 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7401 (m4_warn): Redefine as a do-nothing: it is its invocation that
7402 matters, as warnings are now reported via traces.
7403 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7404 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7405 the latter reveals calls to the former.
7409 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7411 2003-08-21 Akim Demaille <akim@epita.fr>
7413 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

7433 * bin/autoscan.in: Adjust.
7435 2003-08-20 Akim Demaille <akim@epita.fr>
7437 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7438 Reported by Alexandre Duret-Lutz.
7440 2003-08-20 Akim Demaille <akim@epita.fr>
7442 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7443 * bin/autom4te: Adjust.
7444 In particular, be Autoconf tools are really silent when properly
7445 working, bind the verbosity of the 'note' channel to $verbose.
7446 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7447 (&xsystem, &contents): Remove, since they are exported by...

7508 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7509 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7510 shorter column three. Add DESCRIPTION to log file content.
7512 2003-08-13 Derek Price <derek@ximbiot.com>
7514 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7517 2003-08-12 Derek Price <derek@ximbiot.com>
7519 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7520 (AT_CHECK_NOESCAPE): Move core functionality to...
7521 (_AT_CHECK): ...this new macro.
7523 2003-08-07 Derek Price <derek@ximbiot.com>
7525 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7526 (AT_CHECK_NOESCAPE): ...to this new macro.
7528 2003-07-31 Paul Eggert <eggert@twinsun.com>
7530 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7531 in Bash 2.01. Problem reported by Brian Gough in
7532 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7534 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7536 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7537 -lcrt1.o, for OS X. (trivial change)
7539 2003-07-07 Paul Eggert <eggert@twinsun.com>
7541 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7542 inside '#ifndef __cplusplus'. Problem reported by
7545 2003-07-06 Bill Clarke <llib@computer.org>
7547 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7548 'long', not 'int', for benefit of Sun's recent C++ compilers
7549 (trivial change). See:
7550 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

7556 * lib/Makefile.am (autom4te.cfg): Make it read only.
7557 Depend on Makefile since it contains substitutions.
7559 * lib/autom4te.in (args): Add local.at? for Autotest args.
7560 This change was made on autom4te.cfg which is generated.
7561 Reported by Raja R. Harinath.
7563 2003-06-25 Akim Demaille <akim@epita.fr>
7565 * doc/autoconf.texi (Header Portability): sys/mount.h.
7566 From Gareth McCaughan.
7568 2003-06-23 Akim Demaille <akim@epita.fr>
7570 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7571 not all of them. This fixes 1. the fact that when testing
7572 Autoconf there are many many config.log, 2. the incorrect use of
7573 top_srcdir to find config.log.
7574 Don't mix the detailed output of failed test with the summary of
7575 failures. Rather, append detailed log afterwards.
7577 2003-06-23 Akim Demaille <akim@epita.fr>
7579 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7580 always run: output config.log on $at_group_log.
7582 2003-06-23 Akim Demaille <akim@epita.fr>
7584 * tests/torture.at (#define header templates): Don't use quotes in
7585 C++ comments as it puzzles Emacs' sh font-lock-mode.
7587 2003-06-23 Akim Demaille <akim@epita.fr>
7589 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7590 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7591 * tests/atspecific.m4: Rename as...

7594 * tests/local.at: here.
7595 * tests/Makefile.am: Adjust.
7596 * doc/autoconf.texi (testsuite Scripts): Adjust.
7598 2003-06-21 Kevin Ryde <user42@zip.com.au>
7600 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7601 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7602 ensuring we add -std1 for full-ANSI.
7604 * doc/autoconf.texi (hdrindex): New macro.
7605 Add index entries for portability of various standard header files.
7607 2003-06-20 Akim Demaille <akim@epita.fr>

7629 Update from masters.
7631 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7633 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7634 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7635 (TEST_SCRIPT): New diversion.
7636 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7637 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7638 (AT_INIT): Support for expected failures.
7640 2003-06-02 Akim Demaille <akim@epita.fr>
7642 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7644 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7645 Autoconf nor Automake.
7646 (&contents): New, from Automake.
7649 2003-05-28 Paul Eggert <eggert@twinsun.com>
7651 * NEWS, doc/autoconf.texi (Particular Functions),
7652 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7653 is the inverse of localtime.
7655 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7657 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7658 (handle_exec_errors): New function. Work around $! being
7659 altered by WEXITSTATUS.
7660 (xqx, xsystem): Use handle_exec_errors.
7662 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7664 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7665 Do not call `_exit()', simply modify `$?'.
7666 (xsystem): Reset $! before running system, and check it afterward.
7667 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7668 63 for version mismatches.
7670 2003-05-23 Akim Demaille <akim@epita.fr>
7672 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7673 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7674 the middle of a line).
7675 * lib/m4sugar/m4sugar.m4: Likewise.
7676 Remove useless spaces in comments.
7678 2003-05-23 Akim Demaille <akim@epita.fr>
7680 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7681 exit 63, so that we (or Automake's "missing") can tell the
7682 difference with a plain failure.
7683 * doc/autoconf.texi (Notices): Adjust.
7685 2003-05-23 Akim Demaille <akim@epita.fr>
7687 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7688 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7689 White spaces cleanup.
7691 2003-05-22 Jim Meyering <jim@meyering.net>
7692 Paul Eggert <eggert@twinsun.com>
7694 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7695 Remove `#include <stdlib.h>' from the list; we should never
7696 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7697 resulting namespace pollution would cause other tests to fail.
7698 Configure scripts run with some older versions of g++ and HP's
7699 aCC would fail due to such an #include. Problems reported by
7700 Matthew Mueller in <http://bugs.debian.org/120704> and by
7702 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7703 In the test, use the test declaration before including <stdlib.h>,
7704 as that's closer to how it'll be used.
7706 2003-05-23 Akim Demaille <akim@epita.fr>
7708 * doc/autoconf.texi (Header Portability): ucred.h.
7711 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7713 Overhaul Autotest's logging: generate separate log files
7714 in testsuite.dir/NNN/testsuite.log, and append them to
7715 testsuite.log instead of re-running the test verbosely.
7717 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7718 file descriptor, write 0 to at_status_file instead of setting
7719 at_status=0, initialize some new variables (at_status_file,
7720 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7721 to rerun the tests, instead append the at_group_log to the
7722 at_suite_log when a test fails.
7723 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7724 with the AS_MESSAGE_LOG_FD redirected to stdout.
7725 (AT_CLEANUP): save the output status in $at_status_file
7726 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7728 (AT_CHECK): since tests are run with a redirected stdout,
7729 and used to be re-run in verbose mode, turn some $at_verbose
7730 into echo, and don't redirect the output of testing stdout
7733 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7734 the name of the debugging directory and information about
7737 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

7849 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
7851 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
7854 2003-05-06 Akim Demaille <akim@epita.fr>
7856 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7857 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7858 by aclocal.m4 is changed it might require the importing of another
7859 m4 extension file, i.e., aclocal must be run.
7861 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7862 (&parse_args): Use --force with aclocal if required and supported.

7870 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7871 argument instead of a file name, so that the request file remains
7872 open during the whole autom4te run.
7873 ($icache_file): New.
7874 (&freeze): Lock the $icache_file.
7876 2003-04-29 Derek Price <derek@ximbiot.com>
7878 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7879 seperator with m4_append_uniq(). It doesn't work.
7880 (AT_CLEANUP): Add `;' to end of at_help_all.
7881 (AT_INIT): Allow --keywords to be specified more than once. When
7882 grepping $at_help_all for keywords, use the field and keyword
7883 seperators to ensure a complete keyword match. Alter at_prev handling
7884 to support the new --keywords behavior.
7886 2003-04-27 Karl Berry <karl@freefriends.org>
7888 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7889 align better with others. I also made some of the individual
7890 entries on one line, for brevity and to make it easier for me to
7891 sort my dir-example file in the Texinfo distribution :).
7893 2003-04-12 Jim Meyering <jim@meyering.net>

7958 header causes problems.
7960 2003-03-28 Akim Demaille <akim@epita.fr>
7962 * tests/torture.at (Configuring subdirectories): Require aclocal
7963 1.4, otherwise the test fails, as it does support configure.ac.
7964 This fixes the "test 40 failed" bug reports.
7966 2003-03-28 Akim Demaille <akim@epita.fr>
7968 * doc/autoconf.texi (C Compiler): `#line' portability.

7980 use new diversions in preparation for accepting new arguments and

8013 2002/05/09) rejects '#line 32768 "configure"' because the line
8015 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Do not generate
8017 * lib/autoconf/lang.m4 (AC_LANG_SOURCE): Fix comment to match this.
8018 * doc/autoconf.texi (Generating Sources): Document this.

8029 * doc/autoconf.texi (Present But Cannot Be Compiled): New.
8031 2003-02-28 Alexandre Duret-Lutz <adl@gnu.org>
8033 * doc/autoconf.texi (Limitations of Make): Remove the section
8034 about `$<' in inference rules, it was a bogus interpretation of
8035 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
8036 Tru64 make in the "target lookup" section.
8037 (Automake): Automake 1.5+ no longer requires special tools to be
8038 present on the developer's host.
8040 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
8042 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
8043 to a shell that can handle redirection or quoting correctly.
8044 Override SHELL with the shell detected by configure.
8045 Use of $^O suggested by Tim van Holder.
8046 * bin/autom4te.in (BEGIN): Likewise.
8047 * bin/autoreconf.in (BEGIN): Likewise.
8048 * bin/autoscan.in (BEGIN): Likewise.
8049 * bin/autoupdate.in (BEGIN): Likewise.
8050 * bin/ifnames.in (BEGIN): Likewise.

8055 to cope with DOS-style absolute paths, when constructing
8058 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
8059 When constructing paths with IFS=:, quote the path. If we're
8060 constructing a DOS-style absolute path, we don't want to split it
8063 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
8066 2003-02-25 Pavel Roskin <proski@gnu.org>
8068 * bin/autoheader.in: Add missing newline when printing
8069 suggestion how change AC_DEFINE call.

8073 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix typo in
8074 2002-09-01 patch by replacing "test -n" with "test -z".
8075 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
8076 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
8078 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
8079 to fix a mismatch between example and discussion.
8081 2003-02-24 Kevin Ryde <user42@zip.com.au>
8083 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8084 format starting with "-".
8086 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8088 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8089 is not portable inside Makefile.
8091 2003-02-20 Akim Demaille <akim@epita.fr>
8093 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8094 compiler says yeah, but preproc says nope, compiler is right.
8095 Conversely, prompt the reader to send a bug report to the
8096 maintainers of the package, not of Autoconf.
8098 2003-02-20 Klee Dienes <kdienes@apple.com>
8100 * bin/autoreconf.in (autoreconf_current_directory): Properly
8101 handle an empty aclocal.m4.

8105 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
8109 2002-12-23 Paul Eggert <eggert@twinsun.com>
8111 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8112 innocuous variant befor including <limits.h> or <assert.h>. This
8113 works around a bug reported by Albert Chin: HP-UX 11i
8114 (and earlier versions) have a <limits.h> that declares
8115 gettimeofday and many other functions.
8117 2002-12-03 Paul Eggert <eggert@twinsun.com>
8121 * NEWS, configure.ac: Update version.
8123 * doc/fdl.texi: Upgrade to FDL version 1.2.
8125 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8126 nontrivially in main's body, so that f's external declaration is
8127 not optimized away in AIX. This should fix the bug reported by
8129 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8131 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8132 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8133 defined, to support freestanding compilers. This should fix the
8134 bug reported by Momchil Velkov in
8135 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8137 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8138 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
8139 obsolete AC_CHECK_TYPE. The missing empty arg was reported
8140 by Simon Josefsson in
8141 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
8143 * Makefile.maint (www-gnu): New macro.
8144 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
8145 the location has moved.
8147 2002-12-02 Martin Frydl <martin@systinet.com>
8149 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
8150 \(.*\) match is too long and there is something more to be checked.
8151 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
8153 2002-11-15 Akim Demaille <akim@epita.fr>

8164 2002-11-14 Akim Demaille <akim@epita.fr>
8168 * config/config.guess, config/config.sub, config/install-sh:
8169 Update from masters.
8171 2002-11-14 Akim Demaille <akim@epita.fr>
8173 * Makefile.maint: Sync with Bison, i.e.:
8174 (po-check): Scan .l and .y files instead of the
8175 .c and the .h files that they generate. This fixes the bug
8176 reported by Tim Van Holder in:
8177 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8178 Look for N_ as well as for _. Try to avoid matching #define for
8182 2002-11-14 Akim Demaille <akim@epita.fr>
8184 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8185 From Paul Eggert and Albert Chin-A-Young.
8187 2002-11-14 Akim Demaille <akim@epita.fr>
8189 * doc/autoconf.texi (C Compiler): Solitary backslashes.
8190 From Paul Eggert and Albert Chin-A-Young.
8192 2002-11-14 Kevin Ryde <user42@zip.com.au>
8194 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8195 than assigning in main, to avoid HP cc +O3 optimizing it away.
8197 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8199 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8200 option. Process --recheck after parsing all options. Pass -q
8201 option to configure on --recheck.
8202 (AC_OUTPUT): Pass -q from configure to config.status.
8203 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8204 arguments to record.
8205 * doc/autoconf.texi (config.status Invocation): Document
8206 config.status -q option.
8208 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
8210 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
8211 Makefile.in if Makefile.am exists.

8233 Reported by Ezra Peisach.
8235 2002-11-05 Akim Demaille <akim@epita.fr>
8237 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8239 We _have_ to stop using the old compatibility scheme that tried to
8240 avoid useless backslashes because Libtool 1.4.3 contains a
8241 AC_DEFINE([error_t], [int],
8242 [Define to a type to use for \`error_t' if it is not
8243 otherwise available.])
8244 We _have_ to quote the single quote and backslashes with \. The
8245 old compatibility scheme saw that ` was backslashed, and therefore
8246 did not quote the single quote. Hence before this patch, Autoconf
8247 was not compatible with Libtool.
8249 2002-11-04 Paul Eggert <eggert@twinsun.com>
8251 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8269 ($help, $make, &parse_args, &autoreconf_current_directory):
8271 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8273 2002-10-31 Bruno Haible <bruno@clisp.org>
8275 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.

8292 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8293 Make variable, not a shell variable.
8294 Suggested by Bruno Haible.
8296 2002-10-31 Akim Demaille <akim@epita.fr>
8298 * bin/autom4te.in (load_configuration): Reject #args out of any
8301 2002-10-31 Akim Demaille <akim@epita.fr>
8303 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
8304 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
8305 (_AC_RUN_IFELSE): Use it.
8306 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

8331 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
8333 sparc_address_test returns void.
8334 Use it with an argument, as prototyped.
8337 2002-10-29 Akim Demaille <akim@epita.fr>

8598 `@', to tickle Perl's lists.
8599 Reported by Carlos Velasco.
8601 2002-10-18 Akim Demaille <akim@epita.fr>

8637 longer required can still cause errors.
8638 Reported by Alexandre Duret-Lutz.
8640 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

8644 (&freeze): Use &error.
8645 (&up_to_date): If a file that was included according to the cache
8646 is no longer there, then the output is out dated.

8660 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8661 if some file was changed instead of `print'.

8696 file name to enable parallel executions.
8697 From Sam Varshavchik.
8699 2002-10-08 Akim Demaille <akim@epita.fr>
8701 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8702 aclocal invocation, as Gettext macros might not be visible to
8704 Instead of blindly running autopoint, scan configure.ac (not the
8705 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8706 Reported by Paul D. Smith.
8708 2002-10-08 Paul Eggert <eggert@twinsun.com>
8710 Work around problems found when POSIXLY_CORRECT=1 is set.

8716 --warning -> --warnings.

8738 * tests/torture.at (Configuring subdirectories): Be robust to
8739 users who use config.site to require for a cache: in this case,
8740 the two last configure runs, using two different sets of
8741 arguments, trigger a legitimate error.

8905 Suggested by Guido Draheim.
8907 2002-09-13 Akim Demaille <akim@epita.fr>
8909 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8910 (chdir_init) might hang when stat'ing mounted directories.
8911 Reported by Vance Shipley.
8913 2002-09-12 Akim Demaille <akim@epita.fr>

8975 precious variables are.
8976 Suggested by Pontus Skoeld.
8978 2002-09-05 Akim Demaille <akim@epita.fr>
8980 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8981 (ifnames, autoscan, autom4te): Since we don't only depend on
8982 configure.ac variables (such as VERSION etc.), but also on prefix
8983 and so forth, depend on Makefile, not configure.ac.
8984 Reported by Alexandre Duret-Lutz.

8987 2002-09-05 Kevin Ryde <user42@zip.com.au>

9019 * configure.ac: Disable SITE_MACRO_DIR.
9021 2002-09-02 Jim Meyering <meyering@lucent.com>
9023 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9024 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9025 Also, tweak grammar: s/make sure to/be sure to/.

9035 Reported by Raja R. Harinath.

9037 * bin/autoupdate.in: Use error instead of die.
9039 2002-09-01 Paul Eggert <eggert@twinsun.com>
9041 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9042 ordinary shell concatenation rather than echo+tr+sed command that
9043 runs afoul of a long-line-related sed bug in Solaris 8.
9045 * bin/autoheader.in (parse_args): --warning -> --warnings.
9047 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9048 stdout, as traditional "ls" does.

9050 _AC_COMPILER_EXEEXT_O): Likewise.
9051 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9053 * bin/autoconf.as: Add --prepend-include option. This patch was
9054 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9055 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9057 * bin/autoconf.in, configure: Regenerate.
9059 * doc/autoconf.texi (Special Shell Variables): Mention
9060 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9062 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9063 MAILPATH and set PS1, PS2, PS4 to default values, to work
9064 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9065 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9066 the Autoconf documentation specifies; fall back to "unset" only if
9067 this fails. Use a shell for-loop for this rather than an m4 loop,
9068 to shorten the output script.
9070 2002-08-30 Paul Eggert <eggert@twinsun.com>
9072 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9073 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9074 for the CDPATH problem. Document PWD.
9075 (Limitations of Builtins): Document the problem that "cd $foo" and
9076 "ls $foo" may refer to different directories in shells conforming
9077 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9078 example, since the old example is now out of date.
9080 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9081 FOO" and "ls FOO" talk about different directories; this catches
9082 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9085 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9086 of rolling our own unset.
9087 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9088 in practice we needn't worry about CDPATH if unset doesn't work.
9090 * Makefile.in, aclocal.m4, bin/Makefile.in,
9091 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9092 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,

9094 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9095 tests/Makefile.in: Regenerate with Automake 1.6.3.
9097 * config/config.guess, config/config.sub, config/mkinstalldirs:
9100 * configure: Regenerate with self.

9112 2002-08-29 Akim Demaille <akim@epita.fr>
9114 * lib/Autom4te/General.pm (&xqx): New.
9115 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9116 hand, which is not portable.
9118 * bin/autom4te.in: Use them.
9119 Use &error instead of die.
9120 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9123 2002-08-17 Paul Eggert <eggert@twinsun.com>
9125 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9126 default list of compilers to try, since it was long ago superseded
9127 by the ksh fc builtin. Suggested by Steven G. Johnson.
9129 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9131 * doc/autoconf.texi (Invoking autom4te): End the option table,
9132 fixing a bug introduced by the previous patch.
9133 (Limitations of Make): Add a 'target lookup' subentry in the
9134 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9136 2002-07-29 Mark D. Roth <roth@feep.net>
9138 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9139 options and use $AUTOM4TE_PATH.
9140 * doc/autoconf.texi: Remove documentation of autom4te
9141 --include-envvar and --site-macro-subdir options and document
9142 use of $AUTOM4TE_PATH.
9143 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9144 arguments from each language section.
9146 2002-07-29 Paul Eggert <eggert@twinsun.com>
9148 * doc/install.texi: Include copyright symbol in copyright notice.
9150 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9152 (AM_MAKEINFOFLAGS): New macro.
9153 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9154 * Makefile.am (INSTALL): Use the new macros.
9155 Use -o rather than --output, since "missing" does not grok --output.
9157 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9159 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9160 comments do not always work. Never trust the exit status of
9163 2002-07-24 Kevin Ryde <user42@zip.com.au>
9165 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9166 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9168 2002-07-23 Paul Eggert <eggert@twinsun.com>
9170 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9171 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9172 apparently treats PATH="nonexistent" as if it contained ".".
9173 Bug reported by Stefan `Sec' Zehl.
9175 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9177 * doc/autoconf.texi (Limitations of Make): Mention the special

9297 so that Emacs setups GNU style for perl-mode and cperl-mode.
9299 2002-06-27 Paul Eggert <eggert@twinsun.com>
9301 * config/install-sh: Quote $src. Prefer || to test's -o option,
9302 as per "Limitations of Builtins".

9307 "Limitations of Builtins".

9311 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
9312 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
9313 so that we consistently test the just-built programs.
9314 * tests/wrappl.as: Likewise.

9318 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

9334 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9336 * bin/autom4te.in ($cache): Don't define using `$me', the name
9337 of the cache should not depend on the name under which autom4te
9340 2002-06-07 Akim Demaille <akim@epita.fr>
9342 * tests/tools.at (autoconf: forbidden tokens, basic)

9357 AC_FUNC_FNMATCH_GNU.
9359 2002-06-07 Akim Demaille <akim@epita.fr>

9429 version of Autoconf that is discussed.
9431 2002-05-22 Paul Eggert <eggert@twinsun.com>
9433 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77

9441 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9442 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9443 This improves on an earlier suggestion by H. Peter Anvin.
9445 2002-05-16 Paul Eggert <eggert@twinsun.com>
9447 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9448 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9449 Both macros now accept an optional source-dir arg.
9450 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9452 * NEWS: Document this.
9453 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9455 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9456 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9457 not for GNU extensions; this undoes part of the 2000-11-03 change,
9458 reverting to 2.13-compatible behavior.
9459 Add new optional argument DIR.
9460 (AC_FUNC_FNMATCH_GNU): New macro.
9462 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9464 2002-05-08 Paul Eggert <eggert@twinsun.com>
9466 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9467 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9468 and it causes a 'test' syntax error if it fails.
9469 Bug reported by Stephen Gildea.
9471 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9472 If prototypes are supported, use them to check this at compile-time,
9473 instead of trying to check it at run-time. If we must do a run-time
9474 check, assume that setvbuf is standard when cross-compiling, as
9475 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9476 Bug reported by Paul D. Smith.
9478 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9479 argument specifying location of getloadavg.c. This removes a
9480 FIXME. This idea was taken from Jim Meyering's implementation in
9482 * doc/autoconf.texi (Particular Functions): Document this.
9483 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9484 that's what the code does; this fixes a bug reported by
9487 2002-05-03 Akim Demaille <akim@epita.fr>
9489 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9490 autopoint instead of gettextize.
9491 ($uses_alocal): Rename as...
9492 ($uses_aclocal): this.
9493 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9494 Suggested by Bruno Haible.

9500 2002-04-29 Paul Eggert <eggert@twinsun.com>
9502 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9503 files to be 1 second older; just set them to be the same time.
9504 Also, sleep 1 second after the first aclocal, to work around
9505 problems with sub-second time stamps on the input files.
9507 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9509 * doc/autoconf.texi: Mention "set -e -x" lossage
9510 under node "Limitations of Builtins".
9512 2002-04-29 Akim Demaille <akim@epita.fr>
9514 * doc/install.texi: Better wording for setting variables when
9516 From Christian Cornelssen.
9518 2002-04-29 Akim Demaille <akim@epita.fr>
9520 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9521 of lack of $LINENO support, then the test will compare the $LINENO
9522 in testsuite vs. the lineno in the test file. This is wrong, of
9524 Be sure to protect it.
9525 Reported by Patrick Welche.
9527 2002-04-25 Akim Demaille <akim@epita.fr>
9529 * doc/autoconf.texi (Obsolete Macros): Typo.
9530 Reported by Vladimir Volovich.
9532 2002-04-25 Akim Demaille <akim@epita.fr>
9534 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9535 than some of the input files, hence, on the second run of aclocal,
9536 if some of its input are younger, make them older.
9537 Suggested by Paul Eggert.
9539 2002-04-25 Akim Demaille <akim@epita.fr>
9541 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

9551 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9552 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9553 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9554 _AC_SUBST_FILES and _AC_SUBST_VARS.
9555 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9557 2002-04-24 Akim Demaille <akim@epita.fr>
9559 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9560 autoheader, so that automake does not complain about a missing
9561 config.h.in that was to be created.
9563 2002-04-23 Akim Demaille <akim@epita.fr>
9565 * bin/autoheader.in (parse_args): --warning takes an argument.

9615 Minor spelling and grammar fixes.
9617 * doc/autoconf.texi: Follow the outline suggested in the GNU
9618 Sample Texts sections of the Texinfo 4.2 manual. Most
9619 importantly, this makes sure that the copyright notices appear in

9647 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9649 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9650 from aclocal.m4 too.

9659 workaround for ${1+"$@"}.
9660 * doc/autoconf.texi (Shell Substitutions): Explain it.
9661 From Oliver Kiddle and Peter Stephenson.
9663 Have M4sh perform minimal shell sanitizing.
9665 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9667 (_AS_PREPARE): this new macro.

9670 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9672 Adjust Autoconf and Autotest.
9674 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9675 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9676 * lib/autotest/general.m4 (AT_INIT): Likewise.
9677 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9678 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9681 Use this M4sh to generate Autoconf's shell scripts.
9683 * tests/wrapsh.as: New, precursor of wrapsh.in.
9684 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9685 on Autotest and M4sh.
9686 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9687 (wrapsh.in): New target.

9709 directories when descending in a SUBDIRS.
9710 Reported by Ezra Peisach.
9712 2002-04-04 Andreas Schwab <schwab@suse.de>
9714 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9715 contains no literal separators.
9717 2002-04-03 Akim Demaille <akim@epita.fr>
9719 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)

9721 Use dnl, not the KILL diversion.
9723 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9724 (AC_CONFIG_LINKS): here.
9726 Don't use the KILL diversion, as it kills spurious output, which
9727 results in failures being hidden.
9728 Use m4_defn where appropriate.
9729 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9730 after the second argument.
9732 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9733 syntax, as it is provided by M4sugar.

9778 2002-03-27 Paul Eggert <eggert@twinsun.com>
9780 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9781 (AS_SHELL_SANITIZE): Invoke it.

9798 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

9804 2002-03-21 Paul Eggert <eggert@twinsun.com>
9806 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9807 problem with here-document buffer boundaries.
9809 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9810 when reinvoking the shell, to work around problems with installers
9811 who put strange things like "cd" commands in their environments.
9813 2002-03-19 Akim Demaille <akim@epita.fr>

9836 (Limitations of Usual Tools): Add mkdir section.
9838 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9839 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9840 back on AS_DIRNAME to compute prefixes otherwise; this is
9841 roughly what mkinstalldirs does. That way, we need not have
9842 our own filename disassembler. The old disassembler did not
9843 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9845 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9846 Create at_test_all by a series of assignments,
9847 not by a single assignment of a long string. The latter causes ksh
9848 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9849 presumably because of a buffer overrun.
9851 2002-03-14 Paul Eggert <eggert@twinsun.com>
9853 * lib/autotest/general.m4 (at_times_skip):
9854 Renamed from at_times. Now a boolean.
9855 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9856 says 'times: not found'.

9903 2002-03-08 Akim Demaille <akim@epita.fr>
9905 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9906 aliases the actual variables, and modifications of the former
9909 2002-03-08 Akim Demaille <akim@epita.fr>
9911 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9912 because of C-c: have m4 output in tmp files, then mv them.
9914 2002-03-08 Akim Demaille <akim@epita.fr>
9916 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

9944 2002-03-04 Akim Demaille <akim@epita.fr>
9946 * doc/autoconf.texi (Transforming Names): Equality between target
9947 and host is irrelevant.
9948 (Specifying Names, Canonicalizing): Remove all references to the
9949 backward compatibility hooks. Rather, collect them all into...
9950 (Hosts and Cross-Compilation): this new section.
9951 * doc/install.texi (System Type): Ditto.
9952 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9953 that `--host' implies cross-compilation.
9955 2002-03-04 Akim Demaille <akim@epita.fr>
9957 * doc/autoconf.texi (Evaluation Macros): New.
9958 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9960 (_m4_foreach): Define the variant with immediate evaluation so
9961 that it contains exactly the items, not an expression which
9962 evaluation is the current item.
9963 (m4_re_string, m4_re_word): Don't over quote them.
9965 2002-03-04 Akim Demaille <akim@epita.fr>
9967 Instead of having stacking `shift's evaluated at the end, let
9968 `foreach' loops immediately evaluate them.
9970 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9971 $*. This is the n-th time I change my mind, but hopefully this is
9974 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9976 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9977 it was only a hack for m4_text_wrap.
9978 (m4_car2): Remove, replaced by...
9980 (_m4_foreach): Adjust.
9981 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9982 m4_bpatsubst for clarification.
9984 2002-03-04 Akim Demaille <akim@epita.fr>

10034 AC_PREFIX_PROGRAM fails with dashed program names
10036 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

10078 2002-02-05 Akim Demaille <akim@epita.fr>
10080 * doc/autoconf.texi (Making testsuite Scripts): Document
10083 2002-02-05 Akim Demaille <akim@epita.fr>
10085 * lib/freeze.mk: New.
10087 2002-02-05 Akim Demaille <akim@epita.fr>
10089 Implement `autom4te --freeze'.
10091 * bin/autom4te.in (&freeze): New.
10092 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
10093 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
10095 2002-02-05 Akim Demaille <akim@epita.fr>
10097 * bin/autom4te.in (&parse_args): Implement `frozen files are
10098 optional are the sum of the previous files on the command line'.
10099 Also, pass `--reload-state=' on them, so...
10100 (handle_m4): don't.
10101 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10102 (M4sh): Rely on M4sugar.
10103 (Autotest, M4sh, M4sugar): Use frozen files.
10105 2002-01-31 Akim Demaille <akim@epita.fr>
10107 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
10108 * doc/autoconf.texi (Initializing configure): Adjust.
10110 2002-01-30 Akim Demaille <akim@epita.fr>
10112 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
10113 alphanumeric to `-' instead of `_'.
10115 2002-01-30 Akim Demaille <akim@epita.fr>
10117 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10118 for plain code, the other for cross-compilation code. The latter
10119 is now run with GCC only.
10120 * doc/autoconf.texi (Compilers and Preprocessors): New.
10122 2002-01-30 Akim Demaille <akim@epita.fr>
10124 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
10126 * doc/autoconf.texi (Initializing configure): Explain how to
10127 change AC_INIT default values.
10129 2002-01-29 Akim Demaille <akim@epita.fr>
10131 * tests/torture.at (Configuring subdirectories): Use configure.in,
10132 so that aclocal 1.4 works.
10133 Reported by Alexandre Duret-Lutz and Larry Schmitt.
10135 2002-01-28 Akim Demaille <akim@epita.fr>
10137 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10140 2002-01-28 Akim Demaille <akim@epita.fr>
10142 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10143 AUTOTEST_PATH *after* it was set.
10144 Don't put `.' in the PATH: the user should be precise and `./' if
10145 needed. In addition, given that the test suite does some `cd', if
10146 `.' is in the path, the `tested programs' sections will report
10147 programs found in the test suite's directory, while during the
10148 tests (performed in their own directory), these programs are no
10149 longer visible. In other words, the results is confusing and
10151 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10153 2002-01-24 Akim Demaille <akim@epita.fr>
10157 2002-01-24 Akim Demaille <akim@epita.fr>

10160 * doc/autoconf.texi: Finally add Akim as an author.
10162 2002-01-24 Akim Demaille <akim@epita.fr>
10164 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
10165 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
10166 Bourne. Use /bin/sh.
10167 From Andreas Buening.
10169 2002-01-24 Akim Demaille <akim@epita.fr>
10171 * config/config.guess, config/config.sub, config/texinfo.tex:
10172 Update from masters.
10174 2002-01-24 Akim Demaille <akim@epita.fr>
10176 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.

10179 * config/missing.m4, config/sanity.m4, config/select.m4,
10180 * config/strip.m4: Remove, to ease sync'ing with any version of

10185 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
10186 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
10187 Reported by Geir Ove Myhr.
10189 2002-01-21 Akim Demaille <akim@epita.fr>
10191 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
10193 2002-01-21 Akim Demaille <akim@epita.fr>
10195 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10196 message on invalid options.
10197 * bin/autom4te.in (parse_args): Don't use
10198 Autoconf::General::getopt with non valid options.
10200 2002-01-17 Jim Meyering <meyering@lucent.com>
10202 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10203 $ac_cv_exeext so we don't use an old, invalid, cached value.
10205 2002-01-11 Akim Demaille <akim@epita.fr>

10216 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10217 package.m4, since is really depends upon configure.ac, not
10219 * doc/autoconf.texi (testsuite Scripts): Adjust.
10220 * tests/Makefile.am (package.m4): New.
10221 EXTRA_DIST it since its a source.
10223 2002-01-06 Akim Demaille <akim@epita.fr>
10225 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10226 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10227 and PACKAGE_BUGREPORT from here...
10228 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10230 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10231 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10232 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
10233 * tests/tools.at (autoheader): Adjust.
10234 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
10236 2002-01-06 Akim Demaille <akim@epita.fr>

10249 sometimes needing writable input.
10251 2001-12-17 Jim Meyering <meyering@lucent.com>
10253 * doc/autoconf.texi (New Macros): Tweak wording.
10255 2001-12-14 Akim Demaille <akim@epita.fr>
10257 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10258 trailing files, don't apply `-rf' to files which might not be
10259 created by configure (core, core.*, and *.core), but just `rm -f'.
10260 Suggested by Jonathan Kamens.
10262 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10264 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
10266 2001-12-14 Akim Demaille <akim@epita.fr>
10268 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
10270 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
10272 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
10273 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
10274 abs_srcdir, top_srcpath to abs_top_srcdir.
10275 (_AC_OUTPUT_FILES): Adjust.
10276 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
10277 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
10278 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10280 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>

10284 search path from the LPATH line in the $F77 -v output.
10286 2001-12-12 Kevin Ryde <user42@zip.com.au>
10288 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10289 forbidden file descriptors table.
10291 2001-11-26 Akim Demaille <akim@epita.fr>
10293 * bin/autoscan.in (%c_keywords): Build it at top level.
10294 Map to 1 in order to simplify its uses.
10296 2001-11-26 Akim Demaille <akim@epita.fr>
10298 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10299 Remove $filepath, useless.
10300 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10301 variables, they are really part of the tokens.
10302 Split the input line on spaces and then look for tokens.
10303 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10304 because of `lex$U.$(OBJEXT)'.
10305 (&scan_files): Use "@list" instead of join.
10306 * doc/Makefile.am (CLEANFILES): Add *.fns.
10308 2001-11-26 Akim Demaille <akim@epita.fr>
10310 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10311 Remove, replaced by...
10312 * tests/wrappl.in: Be common for all the Perl executables.
10313 In particular autoscan and autoheader want -I.
10314 * configure.ac: Adjust.
10315 * lib/autoscan/headers: errno.h is portable.
10317 2001-11-26 Akim Demaille <akim@epita.fr>
10319 * bin/autoscan.in (used): New.
10322 2001-11-26 Akim Demaille <akim@epita.fr>
10324 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10326 (&scan_sh_file): Remove a duplicate pattern.
10327 (&check_configure_ac): Use long options.
10328 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10330 2001-11-26 Akim Demaille <akim@epita.fr>
10332 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10333 Before, having a line containing the opening of a multi line
10334 comment made the whole line be ignored.
10336 2001-11-26 Akim Demaille <akim@epita.fr>
10338 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10339 (testsuite Scripts): Be one of its subsection.
10340 (Autotest Logs): New.
10342 2001-11-26 Akim Demaille <akim@epita.fr>
10344 Test groups are now run two directories deeper.
10346 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10347 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10349 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10350 top_srcdir, builddir and top_builddir.
10351 Use `at_*dir' relatively to the directory containing the
10352 suite, use `*dir' when relatively to the current group dir.
10354 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10356 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10357 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10358 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10361 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10363 * doc/autoconf.texi (Using System Type): Add an example of `case
10364 $host' usage so people quit using `case $target' everywhere.
10366 2001-11-22 Akim Demaille <akim@epita.fr>
10368 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10369 spotted by Jim Meyering.
10371 2001-11-16 Paul Eggert <eggert@twinsun.com>
10373 This patch implements a `long double' suggestion by Oliver Kiddle.
10375 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10376 static, to catch errors if the value isn't known at compile-time
10377 and the compiler supports dynamic arrays. Change its name from
10378 `_array_' to `test_array' to avoid potential name clashes.
10379 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10380 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10381 better than double. Catch a bug in GCC 2.95.2 x86.
10382 * doc/autoconf.texi (C Compiler): Document the above.
10385 2001-11-13 Akim Demaille <akim@epita.fr>
10387 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10389 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10391 2001-11-13 Akim Demaille <akim@epita.fr>
10393 * lib/autotest/general.m4 (AT_INIT): After having run the test
10394 group, go back to the initial directory, not to at_suite_dir.
10396 2001-11-13 Akim Demaille <akim@epita.fr>
10398 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10399 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10400 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10402 (AT_CHECK_CONFIGURE): Use absolute paths.
10403 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10404 The problem is still the old one: there is no means in M4 (that I
10405 know about) to create a defining macro, because there is no means
10406 to create `$1' etc., therefore, the defining macro ``swallows''
10407 all the arguments meant to the defined macro.
10409 2001-11-13 Akim Demaille <akim@epita.fr>
10411 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10412 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10414 * tests/aclocal.m4: Remove, as it is no longer used.
10416 2001-11-13 Akim Demaille <akim@epita.fr>
10418 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10419 variable names when referring to a single test group, or to
10420 `suite' when referring to the whole test suite.
10421 `at_last_test' is removed: m4 compute at_format itself.
10422 (at_stdout, at_stder1, at_stderr): New variables.
10423 (AT_CHECK): Use them.
10425 2001-11-13 Akim Demaille <akim@epita.fr>
10427 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10429 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10430 Do it as soon as a test fails, don't wait till the end of the test
10432 Don't remove $as_me.[0-9]*, since these files no longer exist.
10434 2001-11-13 Akim Demaille <akim@epita.fr>
10436 * tests/tools.at: Use absolute paths, since we are no longer run
10439 2001-11-13 Akim Demaille <akim@epita.fr>
10441 Now that tests are running in their own private dir, there is no
10442 need to list the files to remove at the end of tests groups.
10444 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10445 (AT_data_files, at_data_files): Remove.
10446 (AT_CLEANUP, AT_DATA): Simplify.
10448 Remove the group dir if !debug && !failed.
10449 * tests/atspecific.m4: Adjust.
10451 2001-11-13 Akim Demaille <akim@epita.fr>
10453 Start a new layout for Autotest: `testsuite' creates
10454 `testsuite.dir' in which the at-check-line etc. files are to be
10455 found, and `testsuite.dir/003' where the test group 3 is run.
10457 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10458 at_check_line_file, at_format, at_test_normalized, at_group_dir
10460 Create the directories.
10461 Use absolute paths for at- files.
10462 (AT_CHECK): Adjust.
10464 2001-11-11 Michael Matz <matz@kde.org>
10466 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10468 (m4_car): Properly quote arguments.
10470 2001-11-13 Akim Demaille <akim@epita.fr>
10472 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10473 with stricter rules on LIBOBJS.
10475 2001-11-12 Paul Eggert <eggert@twinsun.com>
10477 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10478 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10481 2001-11-12 Akim Demaille <akim@epita.fr>
10483 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10485 2001-11-12 Akim Demaille <akim@epita.fr>
10487 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10488 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10489 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10490 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10491 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10492 specify to what the macro should be defined (typically to 1).
10494 2001-11-12 Akim Demaille <akim@epita.fr>
10496 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10499 2001-11-12 Akim Demaille <akim@epita.fr>
10501 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10502 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10503 definition used by Automake where LEX is +/- "${missing} lex" and
10504 `missing' itself contains variables.
10506 2001-11-12 Akim Demaille <akim@epita.fr>
10508 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10509 Now that M4sh pushes BODY, the comments were output at the end of
10512 2001-11-08 Akim Demaille <akim@epita.fr>
10514 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10515 that we can trace macros from aclocal.m4.
10516 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10517 obsoleted, and redirect to the former anyway.
10518 Reported by Ralf Corsepius.
10520 2001-11-08 Akim Demaille <akim@epita.fr>
10522 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10523 processed only if present.
10524 * tests/torture.at (Configuring subdirectories): Use autoreconf
10525 instead of successive calls to autoconf.
10526 Add a nonexistent subdirectory to exercise the patch above.
10527 Reported by Ralf Corsepius.
10529 2001-11-08 Kevin Ryde <user42@zip.com.au>
10531 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10532 doesn't accept .S files.
10534 2001-11-07 Akim Demaille <akim@epita.fr>
10536 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

10538 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10539 * bin/autom4te.in (warn_forbidden): New.
10540 (handle_output): Use it.
10541 Read m4_pattern_forbid with messages.
10543 2001-11-05 Akim Demaille <akim@epita.fr>
10545 * bin/autom4te.in (--normalize): Remove.
10546 * lib/autom4te.in: Adjust.
10548 2001-11-05 Akim Demaille <akim@epita.fr>
10550 * tests/Makefile.am (testsuite): Rename this target as...
10551 ($(TESTSUITE)): this.
10554 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10556 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10557 the --prefix option, also remove it's argument.
10559 2001-11-05 Akim Demaille <akim@epita.fr>
10561 * doc/autoconf.texi (testsuite Invocation): Update.
10562 (Writing testsuite.at): Update.
10564 2001-11-03 Akim Demaille <akim@epita.fr>

10579 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10580 * doc/autoconf.texi (autoreconf Invocation): Update.
10582 2001-11-03 Akim Demaille <akim@epita.fr>
10584 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10585 (@export_forward_subs): New.
10586 Add basename, dirname, and fileparse.

10592 Reported by Ezra Peisach.
10594 2001-11-03 Akim Demaille <akim@epita.fr>
10596 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10597 passed on command line, defaulting to ./configure.ac if present.
10598 (&maybe_autoreconf, File::Find): Remove, unused.
10599 (&autoreconf): If autoconf is not used, don't try to trace.
10601 2001-11-02 Akim Demaille <akim@epita.fr>
10603 * configure.ac: Bump to 2.52g.
10605 2001-11-02 Akim Demaille <akim@epita.fr>
10609 2001-11-02 Akim Demaille <akim@epita.fr>
10611 * config/config.guess, config/config.sub, doc/standards.texi:
10612 * config/lispdir.m4: Update from masters.
10613 * configure.ac: Bump to 2.52f.
10615 2001-11-02 Akim Demaille <akim@epita.fr>
10617 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10618 Don't run aclocal when aclocal.m4 is not from aclocal.
10620 Don't run libtoolize and gettextize if --install is not given.
10622 2001-11-01 Paul Eggert <eggert@twinsun.com>
10624 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10625 be invoked before _AS_LINENO_PREPARE.
10626 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10627 than character ranges.
10629 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10630 invoking AS_BASENAME. Set the locale variables to 'C' if
10631 possible, as POSIX requires this to get the traditional
10633 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10635 2001-10-31 Paul Eggert <eggert@twinsun.com>
10637 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10638 with {}, as that triggers a bug in Bash 2.05.
10640 (_AS_LINENO_PREPARE): Use Sed rather than
10641 Awk. Fix the sed prepass to work even if there are multiple
10642 instances of $LINENO on the same line. Do not substitute for
10643 other variables like $LINENOT. Do not check file dates; such a
10644 check is unreliable on sufficiently fast machines, and removing
10645 the check makes the code simpler and more reliable. Check for
10646 output and chmod failures.
10648 * doc/autoconf.texi (Special Shell Variables): Document
10651 2001-10-31 Akim Demaille <akim@epita.fr>

10659 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10660 provided, while it is optional.
10661 * configure.ac: Adjust.
10663 2001-10-26 Paul Eggert <eggert@twinsun.com>
10665 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10666 lib/Autom4te/Struct.pm:
10667 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10670 * doc/autoconf.texi (Special Shell Variables): Document some
10671 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10673 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10674 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10675 eval $LINENO is not portable in practice.
10677 2001-10-24 Akim Demaille <akim@epita.fr>
10679 * lib/Autom4te/General.pm (backname): New.
10681 2001-10-24 Akim Demaille <akim@epita.fr>

10691 2001-10-22 Paul Eggert <eggert@twinsun.com>
10693 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10694 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10695 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10696 POSIX decided to standardize on the int flavor of strerror_r.
10697 Always do char* test, as there's no reason not to.
10698 Assign to a char* var, to catch strerror_r that returns int*.
10700 * doc/autoconf.texi (Particular Functions):
10701 Document the above changes. Also, document the fact that
10702 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10704 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10706 2001-10-20 Akim Demaille <akim@epita.fr>

10717 (&autoreconf): Display the full path of the configure.ac we are
10719 Trace it only once.
10720 Be sure to honor --force with gettextize.
10721 Always run aclocal.
10722 * doc/autoconf.texi: Adjust.
10724 2001-10-20 Akim Demaille <akim@epita.fr>
10726 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10728 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10729 `intl' is already present, as it refuses unless --force.
10730 (&parse_args): Use -I, --include instead of the old Autoconf
10732 ($localdir, $autoconf_dir): Remove.
10734 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10736 2001-10-19 Jens Petersen <petersen@redhat.com>
10738 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

10757 configure.ac being studied.
10759 2001-10-18 Paul Eggert <eggert@twinsun.com>
10761 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10762 long, to work around a bug in the HP C compiler version HP92453-01
10765 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10766 (AS_BASENAME_EXPR): New macro.
10767 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10768 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10769 and fall back on 'sed' only if the other two fail. This makes
10770 AS_BASENAME act more like AS_DIRNAME.
10771 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10772 contains white space.
10773 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10774 Use AS_DIRNAME, since I think it's now DOS-friendly.
10775 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10776 Allow "dirname //FOO" to return either / or //, as POSIX allows

10781 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

10787 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

10791 2001-10-10 Akim Demaille <akim@epita.fr>
10793 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

10827 bother with $force since...
10828 * lib/Autom4te/General.pm: does.
10830 2001-10-08 Akim Demaille <akim@epita.fr>
10832 * bin/autoreconf.in: Rewrite in Perl.
10833 * configure.ac: Adjust.

10917 empty, and if we can find a shell that does support LINENO,
10918 then set CONFIG_SHELL to that shell and then re-execute
10919 ourselves with CONFIG_SHELL.
10921 2001-10-05 Paul Eggert <eggert@twinsun.com>
10923 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
10924 doesn't exist. Remove *.tmp, as a .tmp file is created during the

10994 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
10995 Don't use nested parenthesization. This patch was originally

10997 but somehow it didn't get incorporated then.
10998 * doc/autoconf.texi (Limitations of Usual Tools):

11004 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11005 Check for `expr' arithmetic overflow, and for compilation failure,
11006 and invoke a new argument $4 if either is discovered.
11007 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
11008 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
11010 2001-09-28 Akim Demaille <akim@epita.fr>
11012 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

11231 * doc/autoconf.texi (Common Shell Constructs): New node,
11232 documenting AS_DIRNAME.
11233 (Limitations of Usual Tools): Refer to it when discussing dirname.
11234 Also, update discussion of POSIX standard to reflect latest draft.
11236 * lib/autoconf/c.m4:
11237 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11239 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11240 Do not pass a first argument with leading '-'
11241 to expr, by parenthesizing initial integers that might be negative.
11243 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11244 now merely checks whether it is an error to pass an argument
11247 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11248 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11249 whether it is a (compile-time) error to pass an argument to

11251 and is all that AC_FUNC_GETPGRP's users really need.
11253 2001-09-18 Akim Demaille <akim@epita.fr>

11267 Add test for AS_BASENAME.
11268 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11269 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11270 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11271 * tests/base.at: Fixed the expected responses. The old ones were
11273 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11274 the documentation claims it should (and how it behaved in 2.13).
11276 2001-09-18 Akim Demaille <akim@epita.fr>
11278 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11279 the AC_CONFIG_COMMANDS invocation.
11280 This also solves the name clash problems.
11281 Don't set the package's ID.
11282 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11283 No longer to be shipped.
11284 (version.in): Remove.

11287 Use `m4_PACKAGE_STRING'.
11288 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11289 the only optional argument is the name of the test suite.
11290 Expect `package.m4' to define the package signature.
11291 * lib/autom4te.in (Autotest): Add `package.m4?'.
11292 * tests/Makefile.am (package.m4): New.
11293 * tests/suite.at: ifnames is a victim.

11298 AC_LIBSOURCE, AC_CONFIG_FILES.

11312 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11313 Always include <stdio.h> and <stdlib.h>. Evaluate
11314 the expression in an extra function before these includes. Call
11315 fprintf "%d" only after ensuring the argument is of type 'int'.
11316 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11318 2001-09-17 Paul Eggert <eggert@twinsun.com>
11320 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11321 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11322 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11323 when they don't exist.
11325 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11326 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11329 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11330 version with the version used by fileutils 4.1, except use

11376 * lib/autotest/general.m4 (AT_INIT): Create and remove
11377 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11378 test suites can cohabit.

11382 * tests/mktests.sh: Don't output banners for empty test files.

11488 2001-09-05 Akim Demaille <akim@epita.fr>
11490 Be ready to handle filenames as stupid as `dnl.at', for if even
11491 the maintainer is dumb enough to do that...
11493 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11494 excellence in M4 quotation: consider `__file__' is active.
11496 And BTW, when invoking m4, pass the --include in the right order:

11520 * doc/autoconf.texi (autoscan Invocation): Adjust.
11522 2001-09-05 Akim Demaille <akim@epita.fr>
11524 CVS GNU M4 doesn't like `undefine(undefined)'.
11526 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
11527 New, extracted from main.
11528 Use IO::File wherever possible.
11529 (input.m4): Be constant, use -I instead of hard coding $tmp.
11530 Therefore be a quoted heredoc.
11531 Don't invoke `_au_disable', since ac was not loaded, but just

11557 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11559 2001-08-31 Akim Demaille <akim@epita.fr>
11561 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11562 (testsuite Scripts): There is no such thing as `atconfig.in'.
11563 And actually one diagram is missing: test suite runtime.
11565 2001-08-31 Akim Demaille <akim@epita.fr>
11567 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11570 2001-08-31 Akim Demaille <akim@epita.fr>
11572 * bin/autoupdate.in (@include): `installcheck' revealed the path
11573 to m4sugar was lacking!
11575 2001-08-31 Akim Demaille <akim@epita.fr>
11577 * man/Makefile.am (.x.1): We really have to pass
11578 autom4te_perllibdir.

11588 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11589 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11590 Use directly autom4te, not autoconf.

11593 2001-08-31 Akim Demaille <akim@epita.fr>

11615 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11616 (autoheader): Pass --force since the test suite goes too fast for
11618 Adjust to the new autoheader messages.
11620 2001-08-31 Akim Demaille <akim@epita.fr>

11632 Drop AC_MACRODIR dead for real.
11633 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11634 `autoheader: `config.hin' is created'.
11635 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11637 2001-08-31 Akim Demaille <akim@epita.fr>
11639 * bin/autoheader.in: Rewrite in Perl.
11640 * tests/autoheader: Adjust.

11645 Map --localdir, --autoconf-dir onto it.
11646 Forward autom4te's options instead of interpreting them.
11647 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11648 There is no such envvar since the inception of autom4te.cfg.
11649 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11650 * bin/autoupdate.in: Adjust, and perform more control.

11652 * tests/autoconf: Dittowise.
11654 2001-08-31 Akim Demaille <akim@epita.fr>

11657 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11659 Use -e, not -f, since /dev/null for instance is OK.
11660 (&parse_args): Adjust.
11661 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.

11670 * lib/Autom4te/General.pm (&find_peer): Remove.
11671 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11672 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11673 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11674 find the executables for it.
11675 * tests/Makefile.am: Major cleanup. Too lazy to document...
11676 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11678 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11679 indeed related to running the test suite, while passing
11680 --autoconf-dir and others is related to running non installed
11681 Autoconf executables. So don't do that, leave it to...
11682 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11683 * tests/autoscan: New.
11684 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

11689 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

11701 Suggested by Paul Eggert.
11703 2001-08-29 Akim Demaille <akim@epita.fr>
11705 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11706 download in a tmp dir.
11708 2001-08-29 Akim Demaille <akim@epita.fr>
11710 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

11730 foo=`(command) 2>/dev/null`

11734 (AT-devnull): this.

11881 the name of the directory they're in, instead of the filename,

11970 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11971 * NEWS, README, README-alpha, TODO, tests/README: This package is
11972 `Autoconf', not `autoconf' (the executable).
11974 2001-08-20 Akim Demaille <akim@epita.fr>
11976 Info readers seem to need `Index' in the index node title :(
11978 * doc/autoconf.texi: Reverse the 2001-08-15 change which
11979 simplified index node names.

12028 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
12029 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

12092 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
12093 `$0.log' as for projects where testsuite is in src, we'd have

12098 * bin/autom4te.in (&parse_args): Recognize --normalize.

12110 * doc/autoconf.texi: Work around Texinfo buglets.
12111 (Transformation Rules): One example is enough, users are expected
12112 to have their brains on. And BTW, use DESTDIR.
12113 (dvar): New macro. Use it.
12115 2001-08-17 Akim Demaille <akim@epita.fr>
12117 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.
12118 * lib/autotest/general.m4 (AT_INIT): Use the relative dir when
12119 looking for ChangeLogs.

12169 * tests/Makefile.am: Use a clean-local rule to remove
12170 autom4te.cache (it's a directory, not a file.
12171 * Makefile.am: Ditto (but maintainer-clean-local).
12173 2001-08-15 Akim Demaille <akim@epita.fr>
12175 * bin/autom4te.in (@m4_warning): New.
12176 (&handle_m4): Use it.
12177 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12178 warnings are issued at each run.
12179 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12180 is in the src tree.
12182 2001-08-15 Akim Demaille <akim@epita.fr>
12184 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
12185 don't waste time running `autoupdate --version' works.
12186 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
12188 2001-08-13 Akim Demaille <akim@epita.fr>

12247 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12249 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12250 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12251 * doc/autoconf.texi (C Compiler Characteristics): Update
12252 documentation for AC_C_BIGENDIAN.
12254 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>

12257 magic values from an object file when cross-compiling.
12258 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12260 2001-08-10 Akim Demaille <akim@epita.fr>
12262 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12264 Suggested by Russ Allbery.
12266 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12268 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12269 current $prefix to the sub-configures.
12271 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12273 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12274 extension (needed on BeOS). Reported by Guido van Rossum.
12276 2001-08-09 Akim Demaille <akim@epita.fr>
12278 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12280 2001-08-07 Akim Demaille <akim@epita.fr>
12282 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12284 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12285 No need to remove the files before and after the each test, before
12286 each test and at the end of the suite is enough.
12287 Display only the children `times', not the shell's.
12288 If the test failed or was skipped, at-times is not available.
12290 2001-08-07 Akim Demaille <akim@epita.fr>
12292 Always produce testsuite.log, including when there are no
12293 failures. This helps getting information on skipped tests, and
12294 duration of the tests. Err, implement the latter btw.
12296 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12297 Dump information on the first run of each test.
12298 (AT_CLEANUP): Create `at-times' containing the duration of the
12301 2001-08-07 Akim Demaille <akim@epita.fr>
12303 The use of `dumpstat' revealed that `len' was used although it
12304 should not. m4_text_wrap was using it, but in the Autoconf world
12305 where it is legal. Hence (i) test M4sh in its own world, not
12306 Autoconf's, and (ii), ahem, fix the bug :)
12308 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12309 does not like `' instead of [].
12310 (AT_INIT): Forbid `^_?AT_'.
12311 And don't output such tokens.
12312 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12313 `script.as', and `autom4te.cache'.
12314 Remove `empty' and `macro' which are no longer used.
12315 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12316 * tests/m4sugar.at: Use it.
12317 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12319 2001-08-07 Akim Demaille <akim@epita.fr>
12321 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12323 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12325 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12327 2001-08-04 Akim Demaille <akim@epita.fr>
12329 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12330 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12332 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12333 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)

12336 2001-08-04 Akim Demaille <akim@epita.fr>
12338 Don't rely on M4sugar outputting the patterns in files, since we
12339 might process the output _without_ running m4, hence without these
12342 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12343 * bin/autom4te.in (@Request::includes): Remove, unused.
12344 (@Request::source): Rename as...
12345 (@Request::input): this.
12346 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12347 (&handle_output): Fetch the patterns from the traces.
12348 `$forbidden' and `$allowed' are constant: use m//o.
12349 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12350 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12352 2001-08-04 Akim Demaille <akim@epita.fr>
12354 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12355 autoconf', i.e., in addition to caching traces, cache the output.
12357 * bin/autom4te.in (Request::cache): Rename as...
12358 (Request::id): this.
12359 ($cache, $icache, $tcache, $ocache): New.
12360 (&handle_m4): Save M4 output in the cache instead of $tmp.
12361 (&handle_output): Adjust.
12362 (&up_to_date_p): Check that the output cache is up to date too.
12363 (top level): Run `&handle_m4' iff force or the cache is invalid.
12364 Run `&handle_output' if the output cache is more recent.
12366 2001-08-04 Akim Demaille <akim@epita.fr>
12368 * bin/autom4te.in ($force): New.
12369 (&parse_args, &print_usage): -f, --force is a new option.
12370 (&handle_output): CPP directives might have spaces after `#'.
12371 (&parse_args): The first file only can be frozen.
12373 2001-08-04 Akim Demaille <akim@epita.fr>
12375 Don't let autom4te compute the `include' traces several times:
12376 first check that the trace cache file is up to date, and then
12377 compare its timestamp with that of the output.
12379 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12380 the preamble. Don't require 5.005 as Autom4te::General does it,
12381 and better yet (use `use', not `require'!).
12382 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12383 Class::Struct as Autom4te::Struct.
12384 * lib/Autom4te/General.pm (File::stat): Use it.
12385 (&mtime): New, export it.
12386 * bin/autom4te.in: Use it.
12387 Declare `$req' is invalid if it is outdated.
12388 Don't declare it valid before saving it if something went wrong.
12390 2001-08-04 Akim Demaille <akim@epita.fr>

12393 must be proposed to the users.

12414 * bin/autoconf.in ($@): Work around the usual sh bug.
12417 2001-08-03 Akim Demaille <akim@epita.fr>
12419 Clean up the handling of the M4 builtins tracing exception.

12424 (@m4_builtin): this.
12425 (%m4_builtin_alternate_name): New.
12426 (&parse_args): Complete the trace requests with alternate names.
