29 * doc/autoconf.texi (Special Shell Variables): Warn about FPATH.
30 (Macro Names, Defining Directories): Don't mention PATH as a name
31 for a fully qualified file name, as this usage violates the GNU
32 coding standards and we shouldn't recommend it.
34 * lib/autotest/general.m4 (AT_INIT): Don't set PATH to the empty
35 string and then assume shell builtins like "test" will work.
37 2007-06-12 Noah Misch <noah@cs.caltech.edu>
39 * lib/autoconf/general.m4 (AC_SUBST): Raise a fatal error if VARIABLE is

78 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp

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

195 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
196 AC_CHECK_TYPE, AC_CHECK_TYPES.
197 * doc/autoconf.texi (Generic types): C types must be type-names
198 (the C terminology), not type-ids (the C++ term). C++ types
199 must not be anonymous.
200 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
201 for C++; this drops support for anonymous struct and union types,
202 which were problematic anyway.
203 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
204 for C++.
206 2007-04-12 Jim Meyering <jim@meyering.net>

214 Report by Pallav Gupta <pallavgupta@gmail.com>.
216 2007-04-11 Paul Eggert <eggert@cs.ucla.edu>
218 * doc/autoconf.texi (Generic Types): Document the restrictions
219 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
220 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
221 with objects too. Document the restrictions on its use.
222 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
223 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
224 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
225 works but the latter doesn't, then it's a valid type.
226 This lets people use function types and so forth.
227 For C++ there doesn't seem to be a simple solution, so leave it alone.
228 (AC_CHECK_SIZEOF): Allow argument to be a variable.
229 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
230 AC_CHECK_TYPE; that wasn't documented or necessary.
232 2007-04-11 Stepan Kasal <kasal@ucw.cz>
234 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
235 when cross-compiling.

253 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
255 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
256 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
257 default still has the problem. Problem reported by Bruce Korb.

282 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
283 nonstandard grep R.E. escape sequences.
285 2007-03-17 Jim Meyering <jim@meyering.net>
287 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
288 (Limitations of Usual Tools): Also list \< and \>, and mention that
289 HP-UX's grep, like the one from Solaris, does not support that syntax.
291 2007-03-09 Stepan Kasal <kasal@ucw.cz>
293 * doc/autoconf.texi (Specifying Names): `--host' does not
294 change the build type.
296 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
298 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
299 suggests AC_CONFIG_HEADERS.

310 universal binaries. Problem reported by Elias Pipping.
312 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
314 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
315 * doc/autoconf.texi (C Compiler): Document this. There is a new
316 extra argument ACTION-IF-UNIVERSAL.
317 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
318 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
319 Reindent for sanity's sake.

332 status of rm so we know when it failed.
333 If cleaning of test dir failed before running the test, warn.
334 Output the line separator in verbose mode before the warning
335 to make clear the warning belongs to the following test.

348 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
350 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to

352 carriage return.
353 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
354 with traditional Awk and begin.
355 * tests/torture.at (Limitations of Builtins): Document the problem

387 * THANKS (people): Update.
389 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>

398 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
400 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
401 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
402 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
403 substitution will still be done by the special code.
404 Report by Jim Meyering.
406 * doc/autoconf.texi (File System Conventions): Mention that
407 $PATH_SEPARATOR is for the build system only.
408 Report by Keith Marshall.
410 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

425 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
427 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
428 early on the reader side, drop stderr of the input to avoid
429 `broken pipe' error output; this may happen even with shell
430 builtin `echo' of some bash versions. Reports by Ian Macdonald
431 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
433 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

447 * doc/autoconf.texi (Signed Overflow Examples): Give more
448 discussion about the allow_superuser_privileges example,
449 and change it a bit to make things clearer.
450 (Optimization and Wraparound): Clarify whether the compiler
451 will generate an infinite loop for the example derived from
452 Autoconf's mktime test.
453 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
454 Also, clarify unsigned multiplication overflow.
456 2007-01-04 Eric Blake <ebb9@byu.net>
458 * bin/Makefile.am (RELEASE_YEAR): New macro.
459 (edit): Use it to supply correct copyright year to scripts.

468 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
470 * doc/autoconf.texi (Integer Overflow): Revised based on today's
471 feedback. The most important changes document what happens when
472 you convert an out-of-range value to a signed integer type, and
473 say that (sum < a) != (b < 0) reliably detects overflow when sum =
474 a + b.
476 * doc/autoconf.texi (Integer Overflow): Greatly expand and
477 rewrite, taking notions from the recent discussion on the gcc and
478 autoconf mailing lists; please see
479 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
480 and follow the many links.
481 (Integer Overflow Basics, Signed Overflow Examples):

483 (Signed Integer Division): New sections.
485 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
487 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
488 preprocessor macro arguments in traced name.
489 * doc/autoconf.texi (Defining symbols): Document longstanding
490 support for AC_DEFINE-ing macros with arguments, and document
491 behavior when the same variable has multiple AC_DEFINEs.
492 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
493 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
494 macros directly, giving much shorter and simpler code.
496 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
498 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
499 space before "$ac_configure_args" to prevent a 'config.status
500 --recheck' failure if ac_configure_args doesn't contain a leading
501 space. This works around a problem with the XEmacs configure.ac,
502 which uses the (undocumented) ac_configure_args variable
503 inconsistently with Autoconf.
505 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
507 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
508 Include <limits.h>, and use its INT_MAX to rewrite the
509 j loop so that it does not overflow 'int'. Problem reported by
510 Ralf Wildenhues in
511 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
512 Play it safe by shifting left by 1 rather than multiplying by 2,
513 as GCC is less likely to optimize this away when the value
514 is signed (when it assumes overflow leads to undefined behavior).
515 Also, don't assume time_t uses two's complement.
517 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
519 * tests/torture.at (Substitute a 2000-byte string): Avoid using
520 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
521 dumps core on it. Report by Tim Rice.
523 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
525 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
526 --disable-option-checking to --help output even when
527 AC_PRESERVE_HELP_ORDER is not used.
528 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
529 --with argument, rather than argument with [-.] replaced by
530 underscores.
531 * NEWS: Fix typo in previous change; the news was in the
532 wrong section.
534 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
536 * NEWS: Warnings are now generated by default for unknown
537 --enable-* and --with-* options.
538 * doc/autoconf.texi (Option Checking): Renamed from
539 (Configure Option Checking). Tighten up the wording a bit.
540 (External Software, Package Options): Cross-reference to Option
541 Checking, and use this to shorten our section.
542 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
543 "$x" to test "x$foo" != x.
544 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
545 Don't warn if $enable_option_checking is "no".
546 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
547 ac_unrecognized_opts to the empty string.
548 Don't echo the unrecognized opts, as this might mishandle
549 backslashes or leading -.
550 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
551 usage next to the other --disable-FEATURE options in the
552 help string.
554 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
556 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
557 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
558 Print warning for unrecognized --with and --enable options
559 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
560 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
561 Disable option checking when subdirs are configured.
562 (AC_OUTPUT): If warnings are enabled, print warning about
563 unrecognized --with and --enable options at the end of
564 the configure output (as well as at the beginning).
565 * doc/autoconf.texi (Option Checking): New node.
566 Document new option warning functionality.
568 2006-12-16 Eric Blake <ebb9@byu.net>
570 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
571 * NEWS: Start news for current version.
573 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
575 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
576 Define HAVE_GETMNTENT to 1, not to the empty string.
577 Problem originally reported by Jochen Friedrich in
578 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
580 This change prompted by a problem report by Andrey Simonenko in
581 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
582 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
583 object-like macros only, in the traditional portable character
584 set.
585 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
586 Warn about attempts to define things that are not identifiers.
587 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
588 awful hack that AC_DEFINEd macro names containing parentheses.
590 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
592 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
593 too drastic, even if Texinfo in theory requires it for info mode.
595 (config.status Invocation): Renamed back from Recreating a
596 Configuration).
597 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
598 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
600 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
602 * NEWS: Version 2.61a.
604 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
605 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
607 * NEWS: Document changes with echo and printf, and the lack
608 of limits on the total size of multi-line values of substituted
609 variables, and the AC_FUNC_FSEEKO fix.
611 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
613 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
614 Writing configure.ac.
615 (Autoconf Input Layout): Renamed from configure.ac Layout.
616 (Recreating a Configuration): Renamed from config.status Invocation.
617 (Obsolete Recreation): Renamed from Obsolete config.status Use.
618 (acconfig Header): Renamed from acconfig.h.
619 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
620 (Writing Testsuites): Renamed from Writing testsuite.at.
621 (Autom4te Cache): Renamed from autom4te.cache.
623 * BUGS: Remove mention of VPATH problem, since it's now documented
624 not to be a bug in the Autoconf build procedure itself, but rather
625 a problem with the proprietary `make' programs.
627 * doc/autoconf.texi (Build Directories): Add a cross reference
628 to VPATH and Make.
630 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
631 * doc/standards.texi: Sync from gnulib.
633 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
634 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
635 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
636 generated automatically.
638 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
640 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
641 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
642 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
644 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
646 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
647 `CEOF$ac_eof' special marker, the awk script cannot contain a
648 line matching `^CEOF', so this is not needed any more.
649 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
650 special marker in the test.
652 2006-12-06 Stepan Kasal <kasal@ucw.cz>
654 * tests/tools.at (autom4te preselections): Use `find -newer';
655 remove one of the sleeps.
657 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
658 more readable, using ...
659 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
661 * doc/autoconf.texi (autoheader Invocation): Do not double-
662 quote the parameter of `AH_BOTTOM' in the example.
664 2006-12-05 Stepan Kasal <kasal@ucw.cz>
666 * doc/autoconf.texi (Configuration Headers): Remove the
667 example with multiple input files.
668 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
669 multiple input files.
671 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
673 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
674 creating the awk substitution script, handle one input line at a
675 time, so that the maximum length of a substituted (multi-line)
676 value is not limited by the size of the sed pattern space.
677 The trade-off is a slightly repetitive sed script.
678 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
679 can only have up to 7 characters, due to Solaris 10 /bin/sed.
680 * tests/torture.at (Substitute a 2000-byte string): Increase the
681 test with several long lines, they should not be caught by sed
682 limits any more.
684 * tests/tools.at (autom4te preselections): New test, to flag
685 entries missing from autom4te.cfg.
686 Report by David Byron <dbyron@hheld.com>.
688 * tests/torture.at (Substitute a 2000-byte string): Actually use
689 AC_PROG_AWK, so the last change works as intended.
690 (Substitute and define special characters): Likewise.
691 (Substitute a newline): Likewise.
693 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
694 instead of `awk' consistently.
695 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
696 * tests/torture.at (Torturing config.status): Test both the
697 result of AC_PROG_AWK and plain awk.
698 (Substitute a 2000-byte string): Likewise.
699 (Substitute and define special characters): Likewise.
700 (Substitute a newline): Likewise.
702 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
704 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
705 can be assigned to a function pointer. Problem reported by
706 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
707 part of a patch by Ralf Wildenhues in that same bug report.
709 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
711 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
712 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
714 2006-12-01 Eric Blake <ebb9@byu.net>
716 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
717 cross-compiling from cygwin to mingw.
718 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
719 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
720 to lib/autoconf/c.m4.
722 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
724 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
725 string for more reliable failure. Wrap the entire test that
726 causes the broken Solaris printf to dump core, in a subshell,
727 so the segmentation fault message is reliably suppressed.
728 Fix shell expansion errors by using /usr/ucb/echo always;
729 avoid an error on systems without it by another subshell.
730 Avoid m4 expansion of `$1'. Set the zeroth argument of the
731 subshell-$as_echo to `as_echo', for better error message.
733 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
735 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
736 `BASH_SOURCE' contain a newline, set them to empty, as they may
737 not be unset.
739 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
741 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
742 years and is too hard to maintain now. The last straw was
743 reported by Jerker Baeck in
744 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
745 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
746 * doc/autoconf.texi (Particular Functions): Move
747 AC_FUNC_SETVBUF_REVERSED from here...
748 (Obsolete Macros): ... to here. Say that it does nothing now.
749 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
750 Turn into (almost) a no-op.
752 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
753 (AC_C_VOLATILE):
754 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
755 These macros are obsolescent and new applications shouldn't need them.
756 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
757 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
758 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
759 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
760 (AC_FUNC_VPRINTF): Likewise.
761 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
762 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
763 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
765 * doc/autoconf.texi (Setting Output Variables): Mention that
766 @VAR1@VAR2 has unspecified behavior. Problem reported by
767 Ralf Wildenhues.
768 * NEWS: Mention this.
770 * Makefile.am: Put only a single '#' into the copyright notice,
771 so that it's also present in the output file. Standardize wording
772 in makefile copyright notices to match GNU coding standards.
773 * bin/Makefile.am: Likewise.
774 * doc/Makefile.am: Likewise.
775 * lib/Makefile.am: Likewise.

780 * lib/m4sugar/Makefile.am: Likewise.
781 * man/Makefile.am: Likewise.
782 * tests/Makefile.am: Likewise.
783 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
784 one-line file.
786 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
788 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
789 in the sed script that mangles the awk script: delete up to the
790 first exclamation mark only.
791 * tests/torture.at (Substitute and define special characters):
792 Test '!' too.
794 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
796 Rewrite config files generation: avoid quadratic growth in
797 the number of substituted variables by using awk instead of sed
798 for the bulk of the substitutions.
799 * NEWS: Mention this.
800 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
801 forbidden in the output (and thus input) file.
802 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
803 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
804 generate just one large awk script for substitutions,
805 eliminating much of the earlier complexity, while adding some
806 new complexity. Only expand the substitution templates at
807 configure time, for smaller configure script size. If
808 _AC_SUBST_FILES are used, test 'awk' for working getline support
809 at config.status time. If absent, interpolate through the
810 shell. The awk script was written with much help
811 from Paolo Bonzini and Paul Eggert.
812 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
813 (_AC_SED_FRAG_NUM): Likewise.
814 (_AC_SUBST_CMDS): Renamed from...
815 (_AC_SED_CMDS): ...this.
816 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
817 * tests/torture.at (Substitute a 2000-byte string): Also
818 substitute a line with 1000 words, and a variable with several
819 long lines.
820 (Substitute and define special characters): Test awk special
821 characters, and put substitution input strings `@foo@' in the
822 output, to test that no recursion happens; test several other
823 combinations from Paolo Bonzini.
825 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
827 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
828 that replaced echo with AS_ECHO where this wasn't necessary.
829 Problem reportd by Ralf Wildenhues.
830 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
831 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
832 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
834 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
836 * lib/freeze.mk (GREP): Removed, no need to initialize this.
838 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
840 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
841 that traditional Awk lacks 3-arg "split". It has it.
842 Mention that FS must be a single character, and a few other
843 99-byte limits of traditional Awk.
844 Mention that if (i in a) doesn't work with traditional Awk.
846 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
848 * tests/autotest.at (BSx641-newline in command):
849 (BS-BS-newline in command, BSx640-newline in command):
850 (Newline-CODE-BS-newline in command):
851 (Single-quote-BS-newline in command):
852 (Single-quote-newline-BS-newline in command):
853 Use printf '%s\n' instead of echo, for portability to hosts
854 where echo interprets backslashes. This will break on hosts
855 that lack printf, but for now let's assume all such hosts
856 are dead (if not, we should get reports of test failures).
858 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
860 'echo' has some portability problems, when given a first argument
861 with a leading '-', or when given any argument containing '\'.
862 Avoid using 'echo' in these cases.
863 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

887 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
888 * bin/autoconf.as: Redo verbose flag implementation, as the old
889 scheme wouldn't work with AS_ECHO.
890 * lib/autotest/general.m4 (AT_INIT): Likewise.
891 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
892 Don't use ECHO_T, since ECHO_N is now reliable.
893 * lib/autotest/general.m4 (AT_INIT): Likewise.
894 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
895 rather than using a here-document to put the script into a file.
896 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
897 use AS_ECHO.
898 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
899 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
900 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
901 bug, but we might as well stop using ECHO_N and ECHO_C internally.
902 * lib/autotest/general.m4 (AT_SETUP): Likewise.
903 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
904 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
905 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
906 operand, as AS_ECHO requires. Avoid double file name expansion.
907 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
908 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
909 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
910 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
911 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
912 Double-quote strings that would otherwise contain M4 comments.
913 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
915 * configure.ac (AC_INIT): Bump to 2.61a.
916 * NEWS: Likewise.
918 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>

923 * NEWS: Likewise.
925 * tests/autotest.at (Macro with backslash in a test title):
926 Comment out for now, as this tests neither fails nor passes
927 reliably. Problem reported by Ralf Wildenhues.
929 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
931 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
932 in previous change, which caused test failures.
934 2006-11-16 Stepan Kasal <kasal@ucw.cz>
936 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out

1019 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set

1021 Imported from a similar patch to gnulib by Bruno Haible.
1023 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
1025 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
1026 * doc/autoconf.texi (C Compiler): Document them.
1027 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
1028 New macros, taken from gnulib.
1030 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>

1041 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
1042 and Stepan Kasal <kasal@ucw.cz>

1049 argument. Extend to check titles printed by ./micro-suite and
1050 ./micro-suite -l and the title in micro-suite.log.
1051 (Backquote in a test title,
1052 Single-quote in a test title,
1053 Double-quote in a test title): Don't expect failure anymore.
1054 (Backslash in a test title): Put a non-whitespace character after the
1055 backslash so that Bourne shells might actually see it as an escape
1056 sequence.
1057 (Brackets in a test title,
1058 Pound in a test title,
1059 Comma in a test title,
1060 Quoted Macro in a test title,
1061 Macro in a test title,

1066 * tests/torture.at (#define header templates): M4-quote this title in
1067 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
1068 The visible effect was a stray [] in the testsuite output.
1070 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1072 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
1073 `trap ... 0' inside a function, for AIX sh.
1075 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1077 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1078 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1079 5363) simply issues a warning when dividing by zero at compile
1080 time. Problem reported by Elias Pipping.
1082 2006-10-26 Eric Blake <ebb9@byu.net>
1084 * THANKS: Update.
1085 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1086 show effect on macros that expand with commas.
1087 Reported by Joel E. Denny.
1089 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
1090 Also work with M4 1.4.8.

1104 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

1111 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
1113 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1114 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1115 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1116 reported by Nelson H. F. Beebe for Coreutils 6.4.
1118 * tests/tools.at (autoconf --trace: user macros): Remove test
1119 for tracing multiline macros, since m4 1.4.7a uses a different
1120 way to number lines. Problem reported by Ralf Wildenhues.
1122 2006-10-24 Stepan Kasal <kasal@ucw.cz>
1124 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1125 /dev/null since the heuristics for interactive behaviour was
1126 fixed in CVS m4.
1128 * bin/autom4te.in: With --force, always refresh the output
1129 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
1131 * bin/autoconf.as: Fix the verbose message at the end.
1133 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

1150 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1151 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
1153 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1155 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
1157 2006-10-19 Eric Blake <ebb9@byu.net>
1159 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.

1161 * lib/emacs/autoconf-mode.el (autoconf-font-lock-keywords): Color
1162 m4_mkstemp.
1163 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.

1179 2006-10-14 Stepan Kasal <kasal@ucw.cz>
1181 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
1182 looking for special shell characters.
1183 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
1184 macro defined by AS_VAR_PUSHDEF before passing it as a
1185 parameter.
1186 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
1187 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

1196 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1198 (Imported from Automake.)
1199 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1200 which incorrectly sets the mode of an existing destination
1201 directory. In some cases the unpatched install-sh could do the
1202 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1203 system. We hope this is rare in practice, but it's clearly worth
1204 fixing. Problem reported by Alex Unleashed in
1205 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1206 Also, don't bother to check for -m bugs unless we're using -m;
1207 suggested by Stepan Kasal.
1209 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1211 Import this change from Automake:

1215 is enabled by default with gnu and gnits strictness.
1216 Report from Bruno Haible.
1218 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
1219 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
1220 gnu and gnits modes.
1222 Import this change from Config:
1224 2006-09-20 Ben Elliston <bje@gnu.org>
1225 * build-aux/config.sub (score, score-*): New.
1227 Import this change from Gnulib:
1229 2006-09-16 Karl Berry <karl@gnu.org>
1230 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
1231 to avoid sectioning errors.
1233 Import these changes from Texinfo:
1235 2006-10-04 Karl Berry <karl@gnu.org>
1236 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
1237 (\quoteexpand): rename to \rquoteexpand.
1238 (\codequoteleft): new def, to look for @set codequotebacktick.

1240 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
1241 (\code): must use new \...Char values, since now ` is active.
1243 2006-08-26 Karl Berry <karl@gnu.org>
1244 * build-aux/texinfo.tex (\textdegree): New command.
1246 2006-08-12 Karl Berry <karl@gnu.org>
1247 * build-aux/texinfo.tex (error \box0): smaller font.
1249 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1251 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
1253 2006-10-13 Stepan Kasal <kasal@ucw.cz>
1255 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1256 added to the template can get mangled.
1258 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1260 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1261 include the default headers, and redefine obstack_chunk_alloc
1262 and obstack_chunk_free. Fixes false failure with glibc.
1264 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1266 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
1267 for backward compatibility with Libtool 1.5.22. Problem reported
1268 by Ralf Wildenhues.
1270 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1272 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
1273 AC_PROG_CC.
1274 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
1276 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1278 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
1279 the NonStop platform.
1280 * doc/autoconf.texi (Posix Variants): Likewise.
1281 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1283 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1284 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1285 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1286 Use a better substitute, by inspecting the output of "ls"
1287 rather than just using ":".
1288 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1289 rather than AS_EXECUTABLE_P, since we needn't worry about
1290 non-regular files here.
1292 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1293 due to configuration hassles with this. See Tonya Underwood's report
1294 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1295 * doc/autoconf.texi (Special Shell Variables): Likewise.
1297 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1298 Stepan Kasal <kasal@ucw.cz>

1303 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1305 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1306 initialization which is not inherited through the environment
1307 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1308 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1310 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1312 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1313 problems with mkdir -p -m.
1315 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1317 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1318 comment about ac_cpp_err; it was incorrect, and anyway
1319 ac_cpp_err is being removed below.
1320 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1321 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1322 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1323 nobody uses it.
1324 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1325 with werror_flag and conftest.err and so forth. This is more
1326 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1327 and anyway the user shouldn't normally want to see this gorp logged.
1328 Problem reported by Ralf Wildenhues.
1329 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1330 empty, not 'no', since the rest of the code uses 'test -z'.
1332 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1334 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1335 Use a single call to AC_DO_TOKENS rather than multiple, for
1336 efficiency.
1337 (_AC_LINK_IFELSE): Test that resulting file is executable.
1338 Problem reported by mwoehlke in
1339 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1341 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1342 than creating a file to use with test -x; this is much faster.
1344 2006-10-02 Bruno Haible <bruno@clisp.org>
1346 * lib/autom4te.in (Automake-preselections): Add
1347 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1349 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1351 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1352 standard error, `experr' should be used, not `expout'.
1354 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1356 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1357 fseeko testing program twice; just use the earlier result.
1358 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1359 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1360 still doesn't let the program compile.
1361 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1362 failed.
1364 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1365 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1366 include it, without including anything else.
1367 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1368 expressions.
1369 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1371 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1373 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1374 `error.h', and include it, for a `error_at_line' prototype.
1375 Use a nonempty format string in the link test.
1376 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1377 for a declaration of wait3.
1379 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1381 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1382 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1383 can apply to constants too, and that it checks for macro defns.
1384 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1385 and simply cast the identifier to void. This handles structure
1386 values. Problem reported by Ralf Wildenhues.
1387 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1389 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1408 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): Avoid `gcc -Wall'
1409 warnings (uninitialized value).
1410 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
1411 present.
1412 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add
1413 parentheses.

1498 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1499 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now

1522 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over

1601 broken lex libraries like native ia64-hp-hpux11.22; see
1602 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1603 work around the problem by preferring an empty LEXLIB to -lfl or
1604 -ll. Let the user set LEXLIB='' to indicate no library needed.
1606 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1607 * README: Likewise.

1858 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1860 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1861 Require that long long int be at least 64 bits wide. C99 requires
1862 this and enough programs depend on it so we should check for it.
1863 Bruno Haible reports in
1864 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1865 that long long int is 32 bits wide with some nonstandard compilers.
1866 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1868 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1870 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1871 to a nonexistent file, so that we don't have to worry about
1872 a local site configuration that doesn't use /usr/local.
1873 Problem reported by Keith Marshall in
1874 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1876 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1878 * doc/autoconf.texi: Be more consistent about using @acronym with
1879 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1880 quite right (it talked about "OSF/Tru64", even though the
1881 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1882 and it even mentioned "OSF 4"!) and at this point there's little
1883 reason to talk about OSF any more, since it died in 1994.
1884 (Specific Compiler Characteristics): Simplify example of
1885 negative-size array.
1886 (File Descriptors): Reorder to make the text flow better.
1887 Remove joke about "appreciate the various levels"; I didn't get it.
1888 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1889 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1890 (File Descriptors, Limitations of Usual Tools):
1891 Tone down the advice against renaming or removing open files.
1892 (Limitations of Usual Tools): Add a new section, on 'rm'.
1894 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1896 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1897 -lXt in LIBS, idea from Karsten Hopp; this was due since
1898 this change:
1900 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1901 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1902 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1903 (which belong to Xt, not X itself). See Debian bug 327655.
1905 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1907 * configure.ac (AC_INIT): Bump to 2.60a.
1908 * NEWS: Update.
1910 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1912 Version 2.60.
1914 * configure.ac, NEWS: Update.
1916 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1918 * config/texinfo.tex: Sync from upstream.
1920 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1921 quadrigraph correctly in traces.
1923 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1924 Fix typos.
1926 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1927 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1928 not defined.
1929 * doc/autoconf.texi (Changed Directory Variables): New node,
1930 to document the whole `datarootdir' business a bit better.
1931 * NEWS: Update.
1932 * tests/torture.at (datarootdir workaround): Extend test.
1933 Prompted by report by Alexandre Julliard.
1935 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1937 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1938 when using default mode of IBM C 6 for AIX. Problem and two-line
1939 fix reported by Larry Jones.
1941 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1943 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1944 about literal '${datarootdir}' if a definition is found in the
1945 output file.
1947 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1949 * NEWS: Use "M4" rather than "m4" when appropriate.
1950 Problem reported by Eric Blake.
1951 * doc/autoconf.texi: Likewise.
1952 Use @acronym around BSD, GCC, and GNU when appropriate.
1953 (Why GNU M4): Renamed from "Why GNU m4".
1954 (Redefined M4 Macros): Mention that Posix
1955 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1956 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1957 to int.
1959 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1961 * bin/autom4te.in (handle_output): Do not forbid the empty
1962 pattern.
1963 * tests/tools.at (autoconf: the empty token): New test.
1965 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1967 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1968 calls, so that we do not care whether they are LIFO or FIFO;
1969 in the m4_wrap, do not check which diversion is the topmost
1970 one, just check that the stack is balanced at the end.
1971 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1972 base diversion forever--pop the previous diversion before
1973 opening the new one; consequently, remove the m4_wrap call.
1974 * lib/autotest/general.m4 (AT_INIT): Likewise.
1975 * tests/m4sugar.at: Do not use
1976 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1978 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1979 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1981 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1982 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1983 Rework example of m4wrap token-pasting trouble so that it doesn't
1984 care whether it's LIFO or FIFO.
1985 Fix some "contrary to"s that are awkward in English.
1987 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1989 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1990 to `yes' instead of `int$1_t' if the type is found, for more
1991 consistent configure output (where $1 is the number of bits).
1992 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1993 Suggested by Bruno Haible.
1995 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1996 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1997 with system headers. Report by Bruno Haible.
1999 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2001 * config/config.guess, config/config.sub: Sync from upstream.
2003 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2004 in order to avoid picking up an older installed frozen m4sh.m4f.
2005 Besides an outdated shell startup, this could have been created
2006 by an earlier M4 version with incompatible frozen file format.
2008 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2010 * README: Recommend m4 1.4.4 instead of 1.4.3..
2011 * doc/autoconf.texi: Likewise.
2012 (Special Chars in Names): Say that $(.FOO) is portable, as
2013 suggested by Stepan Kasal.
2014 (Installation Directory Variables, Build Directories):
2015 (Automatic Remaking, Subdirectories, Fortran Compiler):
2016 (Making testsuite Scripts, Defining Directories):
2017 Quote variable usages better.
2018 (Making testsuite Scripts): Add clean-local rule to makefile
2019 snippet, by Eric Blake.
2020 (Installation Directory Variables): Fix table item font.
2021 Reword slightly to clarify. Generalize advice about
2022 not using special characters to include all file-related
2023 vars, not just VPATH.
2024 (Special Chars in Variables): Warn about special characters in
2025 $(srcdir) too.
2026 (Assignments): Clarify default-value example as suggested by
2027 Ralf Wildenhues in
2028 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2029 (Special Shell Variables): Note leading ./ or ../, as suggested
2030 by Eric Blake.
2031 (Limitations of Builtins): Under cd, warn about CDPATH.
2032 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2033 Ralf Wildenhues.
2035 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2037 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2038 `@var', for texi2html.
2039 (Systemology): Some more word wrapping, for DVI output.
2040 (autom4te Invocation): The short option for `--melt' is `-M',
2041 not `-m'.
2043 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2045 * doc/autoconf.texi: More formatting and English tweaks,
2046 many suggested by Ralf Wildenhues.
2047 Reword to avoid "@code{...}'s" and the like, since it's ugly
2048 with Emacs info mode. discontents -> woes.
2049 Put a few "will"s back. time stamp -> timestamp.
2050 side-effect -> side effect.
2052 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2054 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2055 Warn about $@ not persisting. Problem reported by Julien Danjou in
2056 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2057 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2058 Mention other special chars, too.
2060 2006-06-14 Eric Blake <ebb9@byu.net>
2062 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2064 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2066 * doc/autoconf.texi: Some systematic minor improvements, as
2067 follows. Use "makefile" when talking about makefiles
2068 generally (which might be named "makefile" or "Makefile" or even
2069 "foo.mk"), "Makefile" when talking about a specific makefile
2070 called "Makefile". This unclutters the text from weird quotes
2071 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2072 values" rather than "@var{foo}s" and similar constructs containing
2073 "}s". Use "Make rules" rather than "Makefile rules". Minor
2074 English-language improvements. Change the prefix "sub-" to "sub"
2075 and "re-" to "re".
2076 Put blank lines around examples more consistently.
2077 Avoid "rather" and "very" as intensifiers.
2078 Avoid "will" as an auxiliary.
2079 (Limitations of Make): Split this node into....
2080 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2081 (Leading _ in Macro Names, Backslash-Newline-Newline):
2082 (Backslash-Newline Comments, Long Lines in Makefiles):
2083 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2084 (obj/ and Make, make -k Status, VPATH and Make):
2085 (VPATH and Double-colon, $< in Explicit Rules):
2086 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2087 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2088 New nodes, resulting from splitup of Limitations of Make.
2089 All cross-references changed. Raise the top node from
2090 a section to a chapter, and all subnodes accordingly.
2091 Redo the introductory wording to match the new organization.
2092 (Installation Directory Variables): Use an example that is
2093 closer to what Autoconf actually does. Mention that VPATH's
2094 value should not contain metacharacters or white space.
2095 (Fortran Compiler): Fix a VPATH bug in an example.
2096 (Leading _ in Macro Names): Mention that this problem is no longer
2097 of practical concern.
2098 (VPATH and Make): Reword the advice to make it clearer
2099 that Autoconf and Automake support VPATH in non-GNU make, but
2100 many packages have bugs in this area.
2101 ($< in Explicit Rules): Refer to Build Directories rather
2102 than using a (non-VPATH-safe) example.
2103 (Automatic Rule Rewriting): Mention the sort of disaster that
2104 can ensue with Solaris-style rule rewriting with VPATH.
2106 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2108 * doc/install.texi (Compilers and Options): Weaken the
2109 suggestion to use GNU make for VPATH builds.
2111 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2112 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2114 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2115 in regular expression.
2117 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2119 * doc/autoconf.texi (Installation Directory Variables):
2120 Drop extra @samp from `@table @samp' item.
2121 (Limitations of Usual Tools): Comment fix.
2122 Do not nest @samp just to point to other table items.
2123 (Writing testsuite.at) <AT_CHECK>: The second argument to
2124 `@dvar' is already @samp'ed.
2125 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2126 do not use @var in the second argument.
2128 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2130 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2131 $as_shell.exe too. Problem reported by Andreas Buening in
2132 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2134 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2136 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2137 `unused variable' compiler warning, for `-Wall -Werror'.
2138 Reported by Jaap Haitsma in
2139 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2141 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2143 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2144 case the compiler dumps core. Problem reported for
2145 OpenServer 5.0.7 by Tim Rice in
2146 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2147 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2148 Likewise.
2150 2006-06-06 Tim Rice <tim@multitalents.net>.
2152 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2153 "ERROR" only shows up in "make check" output if there is an
2154 error.
2156 2006-06-06 Eric Blake <ebb9@byu.net>
2158 * tests/tools.at (automatically allowed tokens): Fix typo.
2160 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2162 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2164 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2165 typically overflows on x86 CPUs, even though the C standard
2166 requires otherwise.
2168 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2170 * configure.ac (AC_INIT): Bump to 2.59e.
2171 * NEWS: Update.
2173 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2175 Version 2.59d.
2177 * config/texinfo.tex: Sync from upstream.
2179 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2180 seen, invoke libtoolize with `--ltdl' argument.
2181 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2182 * NEWS: Update.
2183 Suggested by Eric Blake.
2185 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2187 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2188 reported by Ralf Wildenhues.
2189 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
2191 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2193 * THANKS: Update.
2195 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2197 * doc/autoconf.texi: Modernize some of the references to Solaris.
2199 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2201 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2202 message issued by AC_REQUIRE.
2203 * tests/m4sugar.at: Check m4_require's error message.
2204 * tests/base.at: Check AC_REQUIRE's error message.
2205 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2206 to...
2207 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2208 AT_CHECK_M4.
2209 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2210 `expout' as the last parameter.
2211 * tests/tools.at: Adapt to the above change.
2213 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2215 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2216 information about race-free implementations of mkdir.
2218 2006-06-04 Eric Blake <ebb9@byu.net>
2220 * bin/autoreconf.in (help): Document M4 environment variable.
2221 * bin/autoconf.as (Usage): Likewise.
2222 * bin/autom4te.in (help): Likewise.
2223 * doc/autoconf.texi (autom4te Invocation): Likewise.
2225 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2227 * NEWS: GNU make now recommended for VPATH builds.
2228 Mention that some macros are now documented to be obsolescent.
2229 * doc/autoconf.texi:
2230 Prefer "current" to "modern" to describe
2231 currently-used (albeit perhaps old-fashioned) hosts.
2232 Mention which ancient features no longer need to be worried about.
2233 setgid -> set-group-ID
2234 setuid -> set-user-ID (these are the Posix terms)
2235 Fix some misuses of "only".
2236 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2237 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2238 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2239 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2240 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2241 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
2242 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
2243 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2244 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2245 Mention that these macros are obsolescent.
2246 (Installation Directory Variables): shall -> should
2247 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2248 Mention that it's now safe to use 3 and 4.
2249 (Limitations of Usual Tools): cp -r is now specified by Posix.
2250 Omit longwinded and obsolescent discussion of cp -f.
2251 Modernize discussion of expr, ls.
2252 (Limitations of Make): Modernize discussion of VPATH builds.
2253 Mention $? as a workaround in some cases.
2254 * doc/install.texi (Basic Installation):
2255 Mention "./configure; make; make install" first. Be more
2256 specific about why this file is generic. Remove unnecessary
2257 parens. Remove misleading "only". Remove obsolete advice
2258 about csh. Don't say "configure" takes awhile; say it
2259 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2260 and CC=c99 rather than CC=c89, as these are blessed by current
2261 Posix. Recommend GNU make if doing a VPATH build.
2263 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2265 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2266 examples involving shell prompts.
2268 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2269 and Paul Eggert <eggert@cs.ucla.edu>
2271 * doc/autoconf.texi (Here-Documents): Add details about the
2272 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2273 use "here-documents" instead of "here documents".
2275 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2277 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2279 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2281 * doc/autoconf.texi (File System Conventions): Warn about ":"
2282 anywhere in directory names.
2284 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2286 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2287 about quoting the case statement, just in case.
2288 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2289 was fixed in ksh93g; reported by Ralf Wildenhues.
2291 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2293 * doc/autoconf.texi (System Services): Do not document
2294 overriding EXEEXT via ac_cv_exeext=ext.
2295 (Particular Programs) <AC_PROG_MKDIR_P>:
2296 Document that ${MKDIR_P} understands --.
2297 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2298 comment.
2300 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2302 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2303 argument with leading hyphen. Problem reported by Paul Eggert.
2305 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2307 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2308 about quoting ac_try: quote all of it, if any of it seems suspicious.
2309 This means we don't have to worry about ${ or sed any more.
2310 Also, double-quote the case statement, to work around misuses via
2311 underquoting as reported by Ralf Wildenhues in
2312 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2313 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2314 undocumented and dangerous macro.
2315 Problem reported by Ralf Wildenhues in
2316 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2318 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2320 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2321 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2322 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2324 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2326 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2327 since evidently some packages rely on the old, broken behavior.
2328 Problem reported by Ralf Wildenhues in
2329 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2330 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2331 pre-2006-05-26 definitions, but leave in the comments that
2332 these macros are dangerous and should not be used.
2333 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2334 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2335 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2336 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2337 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2339 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2341 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2342 the use of 'tr', since this is our only use of 'tr'.
2344 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2345 and Paul Eggert <eggert@cs.ucla.edu>
2347 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2348 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2350 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2352 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2353 the output file in the `${datarootdir}' test.
2355 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2356 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2358 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2359 mention of `datarootdir' in the input file(s), but literal
2360 `${datarootdir}' in the output file, and we haven't warned yet,
2361 then warn as well: the user may have (erroneously) used
2362 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2363 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2364 * tests/torture.at (datarootdir workaround): Extend this test.
2365 * NEWS: Update.
2367 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2368 and Paul Eggert <eggert@cs.ucla.edu>
2370 * doc/autoconf.texi (autoheader Invocation): The first argument to
2371 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2372 alternatives and clear up the language a bit.
2374 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2376 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2377 ac_config_guess, ac_config_sub, ac_configure.
2378 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2379 Fix typo that prevented an unnecessary space from being removed.
2380 Problems reported by Ralf Wildenhues in:
2381 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2383 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2385 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2386 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2387 Don't use the term "thread-safe" to talk about mkdir race
2388 conditions, since the problem is more a process than a thread
2389 issue. Problem reported by Stepan Kasal in:
2390 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2391 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2392 the test for 'install' more closely. Look at MKDIR_P first.
2393 Look in the PATH, and at /opt/sfw/bin.
2394 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2395 Don't bother to try mkdir -p, since we already check mkdir --version;
2396 just look at the version number. (There's no easy way to check
2397 for race-free implementations.)
2398 * tests/tools.at (autoconf: subdirectories): Adjust to above
2399 changes, since MKDIR_P now might end in "/mkdir -p".
2401 * doc/autoconf.texi (autoheader Invocation): Mention that the
2402 first arg of AC_DEFINE_UNQUOTED must be a literal.
2403 Problem reported by Ben Pfaff in
2404 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2406 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2407 * doc/autoconf.texi (Special Chars in Variables): New section.
2408 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2409 (Installation Directory Variables): Quote $(datadir) better.
2410 (Limitations of Builtins): Describe some of eval's trickiness.
2412 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2413 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2414 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2415 in front of every arg, not just trailing args. Quote apostrophes.
2416 (_AC_EVAL_ECHO): New macro.
2417 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2418 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2419 removed.
2420 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2421 exposed by quoting of eval argument. Put the command on line line
2422 so it logs better.
2423 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2424 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2425 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2426 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2427 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2428 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2429 Use eval more safely.
2430 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2431 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2432 to be replaced.
2433 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2434 lines, exposed by quoting of eval argument.
2436 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2437 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2439 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2440 initialization of `ac_cv_exeext', do not override it if it was
2441 already set, unless it was set to `no', for compatibility with
2442 Autoconf-2.13, and comment this.
2443 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2444 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2445 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2446 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2447 Document that this test may be overridden by setting
2448 `ac_cv_exeext'.
2450 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2452 Revert these two patches:
2454 2006-04-06 Eric Blake <ebb9@byu.net>
2455 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2456 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2457 2006-04-01.
2459 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2460 Clean up _AC_COMPILER_EXEEXT* macros.
2461 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2462 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2463 ac_file to the name of the default output file and call
2464 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2465 initial `rm' of the candidate files...
2466 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2467 the same list in subsequent `rm' calls, and for the temporary
2468 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2469 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2470 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2471 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2472 no longer needed) by libtool. Make it a cache check.
2473 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2474 copied here by mistake.
2475 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2476 _AC_COMPILER_EXEEXT.
2477 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2478 _AC_COMPILER_OBJEXT directly.
2479 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2481 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2483 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2484 Fix description of how the buggy `sed' works.
2486 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2488 Sync from Automake:
2490 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2491 ENOLCK. Only mention `make -j' when applicable. Only raise
2492 fatal errors when `make -j' is involved. Improve error message.
2494 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2496 * doc/autoconf.texi (Here-Documents): We now know more about
2497 the variable expansion in here documents bug.
2498 Thanks to Tim Rice and Stepan Kasal.
2500 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2501 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2503 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2505 * tests/autotest.at (Multiline command from M4 expansion):
2506 No failure to be expected if the shell quotes newlines in
2507 commands in the `set -x' output. Report by Tim Rice.
2508 * THANKS: Update.
2510 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2512 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2513 expansion in the here-documents used by config.status, as that
2514 runs afoul of the Korn shell version M-12/28/93d bug described in
2515 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2516 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2517 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2519 2006-05-23 Jim Meyering <jim@meyering.net>
2521 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2522 Fix typo introduced with 2006-04-02 change. It reversed the sense
2523 of the test.
2525 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2527 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2528 ac_dB slightly, to save bytes in the script.
2529 Max out at 50 lines, rather than 96; this is more likely
2530 (though not guaranteed) to avoid obscure 'sed' failures.
2532 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2534 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2535 `tr -d -' as bad option argument. Work around this by deleting
2536 an unrelated character.
2537 Report by Tim Rice <tim@multitalents.net>.
2539 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2540 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2541 Stepan Kasal <kasal@ucw.cz>
2543 * doc/autoconf.texi (Particular Programs): Do not promise that
2544 we always prefer the GNU version of the program, and that we
2545 search according to PATH; both rules can have exceptions.
2546 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2547 AC_PROG_SED. Move descriptions of limitations
2548 to the Limitations of Usual Tools section.
2549 (Limitations of Usual Tools) <sed>: Mention script length
2550 limitations with Solaris /usr/ucb/sed.
2551 <grep>: Fix wording for empty alternative. Mention that -c and
2552 -l should not be combined, and that -E and -F should not be
2553 combined.
2555 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2556 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2558 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2559 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2561 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2563 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2564 AC_DEFINE is now passed to m4_pattern_allow.
2565 * NEWS: Mention that; likewise for AC_SUBST.
2566 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2567 the parameter to m4_pattern_allow.
2568 * tests/tools.at: Add a check for that.
2570 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2572 * lib/autoconf/status.m4: Fix typos.
2574 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2576 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2577 only the files that this macro generates.
2579 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2581 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2582 the HP-UX sed limitation of 99 commands, labels do not count.
2583 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2584 in the comment.
2585 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2587 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2589 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2590 Import the following fix from coreutils:
2592 2006-01-13 Jim Meyering <jim@meyering.net>
2594 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2595 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2596 not double-quote uses of that variable, to accommodate the rare
2597 case in which getmntent is available in none of the libraries
2598 checked. This happens at least on FreeBSD 5.0.
2600 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2602 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2603 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2604 some other programs unwisely rely on these undocumented vars.
2605 But put in warning comments about them.
2606 Problem reported by Ralf Wildenhues in
2607 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2608 * NEWS: Document that these variables are intended to go away.
2610 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2612 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2613 and set the language to C++ (analogous to the equivalent Fortran
2614 tests).
2616 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2617 * doc/autoconf.texi (C++ Compiler): Document it.
2618 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2619 * NEWS: Update.
2621 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2623 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2624 that caused config.status to generate 100-command sed scripts; the
2625 portable limit is 99.
2627 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2629 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2630 variable `ac_d' instead of `d' to avoid infringing namespace.
2631 Report by Ralf Menzel.
2633 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2635 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2636 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2637 * tests/tools.at (autoconf: subdirectories): New test, taken from
2638 the corresponding problem report by Ralf Wildenhues in:
2639 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2641 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2642 Quote some uses of shell variables if they might suffer unexpected
2643 globbing. This doesn't fix all instances of quoting problems that
2644 I found, just the easy ones that look safe.
2645 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2646 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2647 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2648 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2649 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2650 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2651 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2652 Likewise.
2653 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2654 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2656 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2658 * bin/autoreconf.in ($help): Reword according to the manual.
2659 Suggested by Olly Betts.
2661 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2662 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2664 * bin/autoreconf.in: Pass the directory argument to
2665 `require_configure_ac'. Fix comment.
2666 * tests/torture.at (Configuring subdirectories): Expose this.
2667 Reported by Olly Betts.
2669 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2671 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2672 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2673 Automake as follows:
2675 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2676 `$configure_in' instead of `configure.in', to preserve
2677 directory component.
2679 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2681 * config/config.guess, config/config.sub, config/texinfo.tex,
2682 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2684 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2686 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2687 test for C99 conformance; (bool) 0.5 is an integer constant
2688 expression, but (bool) -0.5 is not. Problem reported by Fedor
2689 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2691 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2693 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2694 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2695 Warn about obsolete install-sh files. Remove stray sentence
2696 fragment and fix cross reference.
2697 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2698 install -d; this undoes the 2006-05-10 change.
2699 (MKDIR_P): Mark with AN_MAKEVAR.
2700 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2701 that we don't require $INSTALL to be thread-safe. Move comments
2702 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2703 of AC_PROG_INSTALL. Output a message saying that we're checking
2704 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2705 MKDIR_P instead of AC_SUBST.
2706 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2707 Special magic for MKDIR_P, too.
2708 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2709 a dnl.
2710 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2712 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2714 Sync from Automake, as follows:
2716 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2717 * config/install-sh: Initialize IFS, so field splitting isn't
2718 turned off later.
2719 * config/mkinstalldirs: Likewise.
2720 * config/missing: Remove superfluous quotes. Replace all uses of
2721 `[' by `test', for consistency, and for..
2722 * config/missing (sed_minuso, sed_output): New variables.
2723 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2724 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2725 Fixes `missing' to detect `--output' for help2man. Fixes
2726 PR automake/483. Report by Dennis J. Linse.
2727 (autom4te): Document in `missing --help'.
2729 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2731 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2732 * config/install-sh: Don't use 'path' to talk about file names,
2733 as per GNU coding standards. Close a race condition reported by Ralf
2734 Wildenhues and Stepan Kasal. There is still a race condition
2735 on hosts that predate Posix 1003.1-1992, but we can't help this.
2736 Don't mishandle weird characters like space on pre-Posix hosts.
2737 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2738 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2739 AC_PROG_MKDIR_P from AS_MKDIR_P.
2740 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2741 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2742 earlier editions are not (including Automake 1.8.3).
2743 Do not suggest mkinstalldirs for thread-safety.
2744 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2745 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2746 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2747 presence of special characters and race conditions.
2748 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2749 in Autoconf's name space.
2751 2006-05-10 Bruno Haible <bruno@clisp.org>
2752 and Paul Eggert <eggert@cs.ucla.edu>
2754 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2755 from Automake with minor changes.
2756 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2758 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2760 * config/install-sh: Update to Automake CVS version, as follows:
2761 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2762 * lib/install-sh: Simplify the expr implementation of dirname.
2763 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2764 * lib/install-sh: Handle --, and diagnose unknown options.
2766 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2768 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2769 `./autom4te' to create `./testsuite', since the `all' target
2770 will ensure its presence, but `installcheck' should not create
2771 the uninstalled wrappers.
2773 * tests/torture.at (Unusual Automake input files): Skip if we
2774 detect automake < 1.8.
2776 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2778 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2779 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2780 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2781 * NEWS: Update.
2783 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2785 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2786 munge (multiple) white space and other oddities.
2787 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2788 single quotes in variable assignment.
2789 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2790 and similar failures by adding multiple spaces, tabs, and other
2791 special characters.
2792 Report and different test suggested by Francesco Romani
2793 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2795 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2796 single quotes, we only need to search for single quotes; this
2797 both simplifies the search pattern, and makes us less
2798 susceptible to `echo' variations for arguments not containing
2799 single quotes.
2800 (_AC_ARG_VAR_VALIDATE): Likewise.
2802 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2804 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2805 `$*' and IFS concatenation issue with traditional shells and
2806 bash-2.04. Report by Seanster@Seanster.com.
2808 2006-05-03 Bruno Haible <bruno@clisp.org>
2810 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2811 precisely which Mac OS X versions have the od problem.
2813 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2815 * doc/autoconf.texi: Use @option systematically.
2817 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2818 and Bruno Haible <bruno@clisp.org>
2820 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2821 about 'od'.
2822 (Integer Overflow): Mention the special case of integer division
2823 overflow.
2825 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2827 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2828 traditional shells like the Solaris one that do not use the
2829 first IFS character for assembling `$*'.
2830 Prompted by a related report from autoconf_bug@nro.ca.
2832 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2833 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2835 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2836 Mention more problems with the -e option.
2838 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2840 * NEWS: Typo.
2841 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2843 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2844 in URLs to improve DVI formatted output (requires texinfo 4.6).
2845 (System Services, Systemology, Shellology): Likewise.
2846 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2847 output.
2849 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2850 continuous text.
2851 (Runtime): Fix macro argument names to match description:
2852 `action-if-found' -> `action-if-true' and similarly.
2853 (Obsolete Macros): Likewise.
2854 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2855 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2856 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2858 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2860 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2862 * ChangeLog: Typo.
2863 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2864 DVI output.
2866 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2868 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2869 /bin/sh set unsorted output.
2870 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2871 * tests/local.at: Likewise.
2873 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2875 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2876 (Integer Overflow, Null Pointers, Buffer Overruns):
2877 (Floating Point Portability, Exiting Portably): New sections.
2878 (Writing Test Programs): Fix some langauge. Recommend exiting
2879 with status 1, not merely nonzero. Clarify exit declaration.
2880 (Run Time): Move C exit status stuff to new Exiting Portably section.
2881 (Systemology): Mention Posix and levenez. Update v7 reference.
2882 (Portable Shell): Mention the Posix shell.
2884 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2886 * bin/autoconf.as (me): Replace by as_me.
2888 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2890 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2891 since as_me isn't set yet.
2893 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2895 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2896 a few minor bugs in this area.
2898 * doc/autoconf.texi (Programming in M4sh): Comment out the
2899 documentation of AS_BASENAME, for now.
2900 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2901 (Limitations of Builtins) <basename>: Do not refer to
2902 AS_BASENAME.
2903 * bin/autoconf.as (me): Don't use AS_BASENAME.
2904 (dir): Remove the unused variable.
2905 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2906 AS_DETECT_REQUIRED. All uses changed.
2907 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2908 All uses changed.
2909 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2910 (AS_BASENAME): Use "basename --" to protect against leading "-".
2911 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2912 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2913 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2914 (_AS_DIRNAME_PREPARE): Likewise.
2915 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2916 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2917 (AS_DIRNAME): Use "dirname --".
2919 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2921 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2922 of "run time" and "run-time" changed to "runtime", for consistency.
2923 * lib/autoconf/fortran.m4: Likewise (in comment).
2924 * lib/autoconf/functions.m4: Likewise.
2925 * lib/autoconf/general.m4: Likewise.
2926 * lib/autoconf/headers.m4: Likewise.
2928 * doc/autoconf.texi (Run Time): Document the exit status situation
2929 with more accuracy and detail.
2931 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2933 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2934 Archive is not officially `GNU' any more. Update URL.
2935 (Defining Directories): Likewise
2936 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2938 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2940 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2941 newline from the `trap' code to finish `config.log'; the NetBSD
2942 /bin/sh resets the exit status after an empty command, as
2943 documented in doc/autoconf.texi.
2944 Reported by Dalibor Topic <robilad@kaffe.org>.
2946 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2948 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2949 Suggested by Bruno Haible.
2951 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2953 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2954 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2955 Instead, just list the shells that we know work.
2956 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2957 changed. Be more cautious about the _cv_ variable.
2958 * tests/tools.at (Syntax of the shell scripts): Check the
2959 _cv_ variable once, at first, to avoid an internal autoconf error
2960 when sh -n does not work.
2962 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2964 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2966 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2968 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2969 use ">&-" since we're only 99.999% sure that this is portable,
2970 and since the MinGW bug is fixed in a different way.
2971 * lib/autotest/general.m4 (AT_INIT): Likewise.
2973 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2975 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2976 before opening config.log, to avoid hitting a bug on MinGW.
2978 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2980 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2981 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2982 This works around a MinGW bug reported by Eric Paire.
2983 Make sure that all writes to the log file append to it,
2984 rather than possibly losing data.
2985 * lib/autotest/general.m4 (AT_INIT): Likewise.
2987 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2989 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2990 description.
2992 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2994 * NEWS: Update.
2996 * configure.ac (AC_INIT): Bump to 2.59d.
2998 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3000 Version 2.59c.
3002 * Makefile.maint (news-date-check): Do not require a leading `*'
3003 before the release date in NEWS.
3005 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3006 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3008 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3009 the instantiated file do not contain the string 'datarootdir'
3010 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3011 @mandir@, replace the reference '${datarootdir}' by the value.
3012 * tests/torture.at (datarootdir workaround): New test.
3013 * NEWS: Advertise this temporary fixup.
3014 Based on a patch by Bruno Haible, reported and analyzed by
3015 Paul Eggert and Noah Misch.
3017 2006-04-12 Eric Blake <ebb9@byu.net>
3019 * tests/autotest.at (Debugging a failed test): Fix comment.
3021 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3023 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3024 all the changes since 2006-04-07.
3026 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3028 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3029 succeeded, but `ln -s file dir' failed, take care to remove the
3030 leftover target before the next test, to prevent its spurious
3031 failure; also make sure `ln file dir' works before selecting it.
3032 Thanks to Keith Marshall for pointing this out.
3033 * THANKS: Update.
3035 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3036 assignments in `at_debug_args', so that we put them correctly
3037 in the `run' script.
3038 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3039 Reported by Eric Blake.
3041 2006-04-11 Eric Blake <ebb9@byu.net>
3043 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3044 top-level tests after micro-suite has been run. Used in...
3045 (Debugging a successful test, Debugging script and environment),
3046 (Debugging a failed test): ...these new tests. The first of these
3047 is fixed by...
3048 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3049 macro, split out from...
3050 (AT_INIT): ...here, so that using -d also generates a run script.
3051 Document that -d inhibits top-level logging.
3052 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3053 inhibits top-level logging; debug scripts are created.
3055 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3056 check.
3057 * tests/autotest.at (Empty test, Empty check): New test to check it.
3059 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3060 from gcc.
3062 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3064 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3065 the files if a problem appears. Make the empty *.at files
3066 read-only, too. Proposed by Ralf Wildenhues.
3068 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3070 * config/Makefile.am: Add comment to force updated Makefile.in.
3072 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3073 space only patch to this file, this patch causes the Makefile.in
3074 files that include freeze.mk to be updated, and thus have a
3075 newer time stamp again, which in turn makes a pristine CVS
3076 checkout have correct time stamps.
3078 * Makefile.maint (cvs-sv): New macro, to be used..
3079 (config.guess-url_prefix, config.sub-url_prefix)
3080 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3081 point to CVS text checkout of Gnulib files.
3082 (copyright-check): Bump current year.
3083 (announcement): Do not hard-wire `./announce-gen'.
3084 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3085 correctly.
3086 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3087 `chmod +x'.
3088 (wget_files): Update config.guess, config.sub, texinfo.tex by
3089 `wget-update', now that their URLs work again.
3091 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3093 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3094 Problem noted by Paul D. Smith.
3096 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3098 * doc/autoconf.texi: Remove unused words from word list.
3099 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3100 .x-sc_trailing_space: New files.
3102 * doc/standards.texi: Sync from gnulib.
3104 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3105 `LIBOBJDIR' as experimental.
3107 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3108 with a target directory; it's internally implemented as `cp'
3109 anyway, but since Autoconf advertises the possibility to use
3110 a target directory when LN_S is `ln -s', we need to find out.
3111 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3112 analyzed by Keith Marshall <keith.marshall@total.com>.
3114 * THANKS: Update.
3116 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3118 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3119 confdefs.h as-is. In general, if it has backslash-newline or the
3120 like, then it doesn't work either to sort or to remove empty
3121 lines.
3123 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3125 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3127 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3129 * lib/autom4te.in (Automake-preselections): Preselect
3130 _AM_SUBST_NOTMAKE.
3132 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3134 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3135 apostrophe within a single-quoted string, as this is the usual
3136 tradition and is easier to read than '"'"'. Don't rely on the
3137 shell treating "$/" like '$/'. Use a more-consistent indenting
3138 style for the trap.
3140 2006-04-09 Eric Blake <ebb9@byu.net>
3142 * tests/autotest.at (Backquote command substitution),
3143 (Multiline backquote command substitution): Remove mistaken
3144 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3145 applied...
3146 (Parenthetical command substitution, Multiline parenthetical
3147 command substitution): here.
3149 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3151 Import macros from gnulib (often changing their name).
3153 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
3154 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
3155 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
3156 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
3157 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
3158 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3159 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
3160 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
3161 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
3162 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
3163 The manual mentions Gnulib more prominently.
3164 * doc/autoconf.texi (Gnulib): New node.
3165 (Pointers): Add Gnulib URL.
3166 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
3167 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3168 Gnulib section.
3169 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
3170 suggest a #define rather than a typedef for _Bool, and mention
3171 Gnulib rather than trying to substitute stdbool code.
3172 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
3173 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
3174 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
3175 AC_STRUCT_DIRENT_D_TYPE.
3176 (Particular Types): Mention stdint.h and inttypes.h as standard
3177 headers too.
3178 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3179 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
3180 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,

3224 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3226 Revert the patch from 2006-04-01 and only improve
3227 _AS_DETECT_BETTER_SHELL:
3229 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3230 skip nonexistent directories.
3231 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3232 only shell candidates which exist.
3233 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3234 * lib/autotest/general.m4 (AT_INIT): No need to give three
3235 parameters to _AS_PATH_WALK.
3237 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3238 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3240 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3241 distinguish m4sugar macros.
3242 * tests/tools.at (autoupdating with aclocal and m4_include):
3243 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3244 test case by Noah Misch <noah@cs.caltech.edu>.
3246 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3248 Revert my change from 2006-03-17, in other words:
3249 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3250 and DUALCASE=1.
3251 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3252 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3253 it is set.
3255 2006-04-07 Eric Blake <ebb9@byu.net>
3257 * doc/autoconf.texi (Programming in M4sh): Document that
3258 AS_MKDIR_P exits the script on failure.
3259 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3261 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3263 * config/elisp-comp, config/install-sh, config/mdate-sh,
3264 config/missing, config/mkinstalldirs: Sync from Automake.
3266 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3267 from Automake.
3269 * doc/make-stds.texi: Sync from gnulib.

3273 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3274 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

3280 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3282 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3283 whether `set' quotes correctly: redirect stderr of the tested
3284 `set', and use a subshell, for Ultrix; use `sed' instead of
3285 `grep' for zsh `set' which may write binary output; match only
3286 at the beginning of a line, to avoid false positives.
3287 In order to avoid false positives by unrelated variables with
3288 multiline content, put the dump algorithm in a subshell and
3289 unset all variables containing newlines (except some which are
3290 special to the shell). Warn about cache variables that are
3291 unset.
3293 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3295 * config/config.guess, config/config.sub, config/texinfo.tex:

3304 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3305 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3306 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3307 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3309 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3310 shell issue with double-quoted command substitutions of native
3311 commands.

3332 * tests/Makefile.am (maintainer-check-posix):
3333 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
3335 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
3336 ac_config_<foo>s again, sometimes normalized, sometimes not.
3337 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3338 (AC_CONFIG_COMMANDS): Do not do so here.
3339 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3340 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3341 2005-07-25 rewrite. Noticed by Noah Misch.
3343 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3344 _AC_PRESERVE_HELP_ORDER, ...
3345 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3347 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3348 inside m4_expand_once; it is redundant.
3350 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3351 for --help from Cygnus `configure.'
3353 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

3363 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
3364 Noah Misch <noah@cs.caltech.edu>
3366 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3367 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3368 * doc/autoconf.texi (Help Formatting): New node.
3369 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3371 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3373 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3374 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3375 lib/autoconf/types.m4, lib/autotest/general.m4,
3376 tests/mktests.sh, tests/torture.at: White space cleanup:

3379 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
3381 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
3383 2006-04-05 Eric Blake <ebb9@byu.net>
3385 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
3386 empty test suite works.
3387 * tests/autotest.at (Empty test suite): Remove xfail.
3389 2006-04-05 Noah Misch <noah@cs.caltech.edu>

3392 TAGS to ac_config_<foo>s.
3393 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
3394 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
3395 normalizing it, consistent it with previous releases.
3396 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3398 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3400 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3401 Use simplified args that Eric Blake originally suggested.
3403 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3405 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3406 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3407 Use 'comm' rather than N instances of grep; this also fixes a bug
3408 whereby substrings were incorrectly matched, causing us to not
3409 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3410 (exclude_list): Exclude empty macros.
3411 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
3413 Use awk rather than grep -E or egrep, to avoid

3416 Switch from grep to awk syntax.
3417 (ac_exclude_script): Renamed from ac_exclude_egrep.
3418 (au_exclude_script): Renamed from au_exclude_egrep.
3420 2006-04-04 Noah Misch <noah@cs.caltech.edu>
3422 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
3423 a subdirectory subject to Cygnus `configure'.
3424 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3426 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3427 report request when we have no AC_PACKAGE_BUGREPORT.
3429 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3431 * THANKS: Update.

3434 generated files.
3436 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
3437 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
3438 typedef'ed restricted pointer, to catch a compiler bug on
3439 HP-UX 11.x, and fix warnings so it passes with -Werror.
3440 (_AC_PROG_CC_C99): Likewise.
3441 Reported by Albert Chin <china@thewrittenword.com>.
3442 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

3461 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
3462 to log, point to testsuite output tree.
3464 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
3466 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
3467 * doc/autoconf.texi (Function Portability): Mention that C++

3471 Remove; all uses removed.
3472 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

3492 Clean up _AC_COMPILER_EXEEXT* macros.
3494 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3495 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3496 ac_file to the name of the default output file and call
3497 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3498 initial `rm' of the candidate files...
3499 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3500 the same list in subsequent `rm' calls, and for the temporary
3501 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3502 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3503 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3504 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3505 no longer needed) by libtool. Make it a cache check.
3506 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3507 copied here by mistake.
3508 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3509 _AC_COMPILER_EXEEXT.
3510 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

3543 Autoconf version number despite a zero- or one-argument AC_INIT.
3545 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
3546 subordinate tools.
3547 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
3548 * doc/autoconf.texi (autoreconf Invocation): Document it.
3550 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
3551 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

3557 rm failed to remove it.
3559 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3561 * bin/autoupdate.in: Redefine m4_location so that warnings print
3562 the correct lines of the input file by subtracting..
3563 (_au__first_line): ..this new definition.
3565 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
3566 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
3567 Remove stray newline in output.
3568 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
3569 AC_DEFUN this for autoconf, including the obsoletion diagnose.
3570 Fixes autoupdating of code where the replacement output contains
3571 m4sugar macros.
3572 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
3573 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

3575 * tests/tools.at: Several new tests for all of this.
3576 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
3577 hairy details.
3578 The AC_LANG_SAVE issue was reported against Libtool by
3579 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
3580 Kristian Kvilekval <kris@cs.ucsb.edu>.
3582 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3584 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3585 switch all of them on and of when necessary. Fixes the bug when
3586 m4sugar macros (e.g., m4_define) were expanded after the first
3587 automatic update (e.g., after AC_PREREQ or AC_INIT).
3589 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

4137 (Limitations of Usual Tools): Document the weird restrictions
4138 that Posix has about { }. Use better quoting.

4226 Factor functionality to..
4227 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
4228 `AC_SUBST($1)' in the public version.
4229 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
4230 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

4280 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
4281 AC_LANG_PROGRAM, fixing a typo. Don't give details about
4282 the inner workings of AC_LANG_FUNC_LINK_TRY.
4283 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
4284 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4285 by the function rather than ignoring it.
4286 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4287 comparing its address. Intel's interprocedural optimization was
4288 outsmarting the old heuristic. Problem reported by
4289 Mikulas Patocka.
4291 2005-10-19 Stepan Kasal <kasal@ucw.cz>
4293 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

4300 2005-10-04 Stepan Kasal <kasal@ucw.cz>
4302 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
4303 before removing it (chmod -R u+rwx); there are three instances of this.
4305 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4306 Stepan Kasal <kasal@ucw.cz>
4308 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4309 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4310 make its content writable before removing it. Remove an errorneous
4311 comment from the end, where the logs of the failed tests are copied
4312 to the main log file.
4314 2005-09-27 Stepan Kasal <kasal@ucw.cz>
4316 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
4317 in case the computer is too quick. Double quote the configure.ac
4318 snippets.
4320 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
4321 problems if the testsuite were running too fast.
4323 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4325 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4326 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4327 (which belong to Xt, not X itself). See Debian bug 327655.
4328 * NEWS: Mention this.
4330 2005-09-07 Stepan Kasal <kasal@ucw.cz>
4332 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
4334 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
4336 * config/move-if-change: Don't output "$2 is unchanged";
4337 suggested by Ben Elliston. Handle weird characters correctly.
4339 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4341 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4342 calls, so that the final expansion of this macro is shorter.
4343 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4344 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4345 the cleanup there. Use AS_VAR_* macros, to be more general.
4346 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4348 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4350 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
4352 2005-09-01 Stepan Kasal <kasal@ucw.cz>
4354 * doc/autoconf.texi (Configuration Headers): Add an index entry
4355 for AH_HEADER.
4357 2005-08-26 Pavel Roskin <proski@gnu.org>
4359 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
4360 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
4361 running xmkmf.
4363 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4365 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4366 The previous patch didn't work, so try a better one.
4368 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4370 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4371 in the example. Reported by Bruno Haible.
4372 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4373 "if $undefined_var;" succeeds with my shell.
4375 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4376 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4377 but change the m4_divert_text to m4_divert_once.
4379 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4381 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4382 Work around bug in Solaris /usr/xpg4/bin/awk.
4383 The bug is present in at least Solaris 8 through 10.
4385 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4387 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4388 some evil values and relying on the fact that $* concatenates the
4389 parameters by the first character from IFS.
4391 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4392 Stepan Kasal <kasal@ucw.cz>
4394 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4395 first header appears, define AH_HEADER.
4396 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4397 Update limitations about when to call AC_CONFIG_HEADERS.
4398 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4399 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4400 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4401 ``Configuration Actions''; fix their index entries.
4403 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4404 options correctly. Process N-M as M-N if M is smaller than N.
4405 Process ranges correctly so that N-N will run only N.
4406 Sort and uniquify the tests that will be run. If there is more
4407 than one test, reinsert the banners for the tests.
4408 * tests/autotest.at (Keywords): Unmark XFAIL.
4410 2005-08-23 Stepan Kasal <kasal@ucw.cz>
4412 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4413 before passing the macro name to AH_TEMPLATE.
4415 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4416 now opens log after option processing; in particular, --version
4417 and --help do not touch config.log.
4419 * Makefile.maint: Revert the change from 2005-08-12.
4421 2005-08-22 Stepan Kasal <kasal@ucw.cz>
4423 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
4424 common code to...
4425 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
4427 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4429 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4430 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4431 Language cleanup.
4433 * doc/autoconf.texi (Defining Symbols, Changed Results):
4434 Prepend to LIBS, not append, in examples.
4436 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4438 When building in place, set srcdir="."; suggested by Tim Van Holder.
4440 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4441 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4442 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4443 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4444 does not mean "no --srcdir option".
4446 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4448 * tests/autoscan.at (autoscan): New file.
4449 * tests/suite.at: Use it.
4450 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4451 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
4453 * tests/autotest.at (Keywords): Test keywords combinations.
4455 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4457 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4458 add "2>&1"; gzip 1.2.4 prints help on stderr.
4460 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4462 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4463 was pushdef'ed twice while popped only once. Push it only once.
4464 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4466 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4468 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
4469 prefixed by mere "===", not "configure: === ".

4473 * Makefile.maint: Update from Bison.
4475 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4476 "<tab>" in comment, so that the point is understandable.
4478 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4480 Rewrite substantial part of lib/autoconf/status.m4.
4481 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4482 and CONFIG_COMMANDS are not processed in four separate loops.
4483 Instead, there is one main loop. This alows that the common code
4484 is expanded only once, thus config.status (and configure) is smaller.
4486 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4487 the AC_LIST_FILES and cousins macros are no longer used.
4489 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4490 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4491 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4492 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4493 contain the initialization, nor the for loop, nor the associated
4494 commands; all these go to ...
4495 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4496 _AC_OUTPUT_CONFIG_STATUS.
4497 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4498 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4499 (_AC_OUTPUT_FILE): The creation of the sed script ...
4500 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4501 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4502 _AC_OUTPUT_MAIN_LOOP.
4503 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4504 _AC_CONFIG_COMMANDS): Use ...
4505 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4506 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4507 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4508 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4509 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4510 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4511 ... new macros.
4512 (_AC_CONFIG_UNIQUE): Update.
4513 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4514 Replaced by this ...
4515 (_AC_LIST_TAGS): ... new common macro.
4516 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4517 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4518 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4519 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4520 this didn't belong to the `config commands' section.
4521 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4522 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4523 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4524 to the `config commands' section either.
4525 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4526 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4528 ... and many changes to the comments nearby.
4530 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4531 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4532 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4533 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4534 (#define header templates): The comment at the top of the generated
4535 header now includes the name(s) of the source file(s).
4537 Several unrelated small changes:
4539 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4540 parameter to AC_DIAGNOSE.
4541 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4542 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4543 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4544 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4545 with AU::AC_OUTPUT.
4546 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4547 in AC_OUTPUT doesn't double-quote it either.
4548 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4549 parameters.

4572 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4573 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4574 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4575 (AC_ARG_VAR): ... here.

4588 to INIT_PREPARE.
4589 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4590 its value to shell variable ac_precious_vars and call
4591 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.

4633 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

4643 configure_input, top_builddir, srcdir, etc.
4644 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4645 PATH_SEPARATOR in AUTOTEST_PATH.
4647 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

4655 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

4681 for --help in that case.
4683 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4684 matches the order of execution. No code changed.

4706 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4707 (AC_SUBST): Call it.
4708 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4709 the directory specific variables; but don't call it for configure_input.
4711 2005-06-28 Derek Price <derek@ximbiot.com>
4713 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4714 addition.
4716 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4718 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4719 directory have inherent problems with special characters like spaces,

4738 because we really don't support spaces and suchlike in dir names.
4739 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4740 Don't worry about backslashes in srcdir; it can't happen now.

4769 (Special Shell Variables): Fix sed code this in the example.
4770 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4771 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4773 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4774 expand to the empty list. Don't use two pairs of m4_changequote,
4775 it's not necessary.

4783 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4784 * doc/autoconf.texi:
4785 Don't mention Solaris versions so much, if a
4786 problem is common to all extant versions of Solaris. Say "SunOS
4787 4" instead of "SunOS" for SunOS 4.
4788 (awk): Mention more of the limitations of traditional Awk.
4789 (cat): Don't talk about cat -v.
4791 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

4822 quotes and backslashes. Patch from Derek Price.

4831 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4832 -u, since it outputs chatter if the input files are the same.
4833 Problem reported by Ralf Menzel.
4835 2005-06-08 Derek Price <derek@ximbiot.com>
4837 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4838 renaming them since they are about to be redefined anyhow.
4840 2005-06-08 Derek Price <derek@ximbiot.com>
4842 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4843 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4844 Move m4_undefine to alphabetical order.
4846 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>

4849 * doc/autoconf.texi (Introduction): Likewise.
4850 Reword to avoid some formatting glitches.
4851 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4852 Clarify explanation of HP compiler bug.
4853 Redo example output tp match current CVS snapshot.
4854 Use @example.org in email addresses when the examples
4855 might get inadvertently cut-and-pasted into user code.
4856 Remove example of autom4te usage that doesn't seem to work now.
4857 Use modern AC_INIT (except when the example is meant to be
4858 shown with Autoconf 2.13).
4859 Update ksh info for Solaris 9 and later.
4860 KB -> kB.
4861 Modernize description of Automake versions a bit.

4872 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4873 Tru64 ksh pattern matching bug. Reported against Libtool by
4874 Albert Chin <libtool@mlists.thewrittenword.com> and
4875 Nicolas Joly <njoly@pasteur.fr>.
4877 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4879 m4_cdr of one-member list was [[]] (one-member list containing an
4880 empty string) instead of [] (an empty list. Callers were skewed to
4881 match this misbehaviour. As a consequence of this:
4882 - m4_foreach([x], [], [foo]) expanded to `foo', while
4883 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4884 This bug has been fixed:
4886 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4887 expand to an empty string; print error msg if called without
4888 an argument list.
4889 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4890 misbehaviour; handle [] and [[]] correctly.

4898 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4900 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4901 swallow records with more than 99 fields.
4902 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4903 parse the long line.
4905 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4907 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4908 swallow literals longer than 399. Reported by Ralf Wildenhues.

4920 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4921 (DISTCLEANFILES): Remove $(check_SCRIPTS).

4926 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4927 expression of unbounded size when processing the --list
4928 option. This runs afoul of a limit of 399 bytes per regular
4929 expression on AIX. Problem reported by Ralf Wildenhues.

4940 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4942 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4943 now contain newlines, and substituted files must be referenced on
4944 a line alone; the sed scripts to substitute them are now very
4945 different.

4947 commands can be put in a sed script portably.
4948 * doc/autoconf.texi (Setting Output Variables): Document above

4961 classes in shell scripts. The test was too brittle.
4963 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4965 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

4997 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4998 (ac_top_builddir): ... this ...
4999 (ac_top_build_prefix): ... to this; the old name is also kept, for
5000 backward compatibility.
5001 (ac_top_builddir_sub): New variable, without the trailing slash,
5002 always nonempty.
5003 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
5004 * doc/autoconf.texi (Configuration Actions): Rename
5005 ac_top_builddir to ac_top_build_prefix.
5006 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
5007 at_top_builddir to at_top_build_prefix.
5008 * lib/autotest/general.m4 (AT_INIT): Likewise.
5010 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5012 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
5013 of confdefs.h .
5015 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5017 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
5018 argument to m4_foreach. I guess it was necessary in the past,
5019 but I think it's a no-op now.
5021 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5023 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5024 ``cat <<_ACEOF'' commands to one.
5025 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
5026 * lib/autoconf/status.m4: On various places, use expr instead of
5027 ``echo|sed.''
5028 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
5029 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
5030 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
5031 a range.
5032 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
5033 the wrong patterns between ``case'' and ``esac.'' The previous
5034 code had false positives.
5036 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
5038 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
5039 as on 2005-05-02.
5040 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
5041 Mention LIBOBJDIR.

5081 2005-05-13 Stepan Kasal <kasal@ucw.cz>
5083 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
5084 check.
5085 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
5086 enough arguments, similarly as in m4_bpatsubsts.
5088 2005-05-12 Stepan Kasal <kasal@ucw.cz>
5090 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
5091 of absolute paths.
5093 2005-05-11 Stepan Kasal <kasal@ucw.cz>
5095 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
5096 for absolute directory names in one loop.
5097 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
5098 abbreviations of --version and --debug.
5100 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
5102 * doc/autoconf.texi (Autoconf Language): Be more precise about
5103 quoting rules. Problems noted by Stepan Kasal.
5104 Also, throughout this document, be more careful about white space.
5105 "blank", "white space", and "space" all have different meanings
5106 and we should be careful to say what we mean.
5108 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
5110 Fix C++ related problems reported by Werner Lemberg.
5111 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
5112 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
5113 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
5114 avoid problems with C++ and throw.
5115 * tests/compile.at: .cpp, not .cc.
5117 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
5119 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5121 * doc/autoconf.texi (Generic Functions): Typos.
5123 2005-05-02 Gary V. Vaughan <gary@gnu.org>
5125 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
5126 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
5127 set by latest automake.
5129 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
5131 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
5132 outputs 0 on GNU/Linux these days.
5134 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
5136 * doc/autoconf.texi (Autoconf Language): Add more description
5137 about quoting heuristics.
5138 (Limitations of Builtins): Describe "set -" problems.
5140 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5142 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
5143 not newline.
5145 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5146 by AC_DEFINE; it was a mistake.
5147 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5149 2005-04-25 Stepan Kasal <kasal@ucw.cz>
5151 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
5153 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5155 * doc/autoconf.texi (External Software): Quadrigraphs are not
5156 processed correctly in AS_HELP_STRING; avoid this in the examples.
5157 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5158 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5159 comment and reduce m4_default([foo], []) to [foo].
5160 (m4_strip): Update the explanation.
5162 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5164 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5165 Remove core.conftest.* too; it's generated by Tru64 5.1.
5166 Problem reported by Jennis Pruett.
5167 * lib/autoconf/functions.m4
5168 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5169 Don't bother to remove core files; AC_RUN_IFELSE should do that
5170 for you.
5172 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5174 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
5176 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
5178 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
5179 Report from Horst Wente.
5181 2005-04-15 Stepan Kasal <kasal@ucw.cz>
5183 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
5184 the comment.
5186 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
5188 * doc/autoconf.texi (External Software, Package Options): Add
5189 examples showing how to implement --with-* and --enable-* options.
5191 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
5193 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
5194 as well as configure.in. Problem reported by Gregorio Guidi.
5196 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
5198 * doc/autoconf.texi (Particular Functions): Use gnulib's current
5199 pattern for alloca snippet.
5201 2005-04-04 Stepan Kasal <kasal@ucw.cz>
5203 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
5205 2005-04-01 Stepan Kasal <kasal@ucw.cz>
5207 * doc/autoconf.texi (Generic Programs): Fix a typo.
5209 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
5211 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
5212 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
5214 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5216 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5217 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5218 whole-archive (-zallextract, -zdefaultextract) options in the hope of
5219 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5220 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5222 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5224 * NEWS: The configure command now warns you if you attempt to use
5225 a directory whose name contains a special character like space,
5226 newline, or "\".
5227 * doc/autoconf.texi (Installation Directory Variables): Allow
5228 "," in file names. Do not use \@; it's not a portable regexp.
5229 * bin/Makefile.am (edit): Likewise.
5230 * lib/Makefile.am (edit): Likewise.
5231 * tests/Makefile.am (edit): Likewise.
5232 * tests/semantics.at: Likewise.
5233 * tests/torture.at: Likewise.
5234 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
5235 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
5236 * doc/autoconf.texi (File System Conventions): Warn about
5237 unportable file names.
5238 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5239 (AC_INIT): Use it.
5240 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5241 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5242 ac_pwd, and quote srcdir.
5243 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5245 * doc/autoconf.texi: Fix some systematic formatting problems.
5246 ".)" needs a following @: if not at the end of a sentence, and
5247 similarly for "!)". "etc." should be preceded by a comma.
5248 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5250 2005-03-22 Bruno Haible <bruno@clisp.org>
5252 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5253 argument is often called 'build-aux'.
5255 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5257 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5258 macro AC_TRY_LINK is obsolete.
5259 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5260 `AC_CONFIG_FILES'.
5262 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5264 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5265 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5266 from a Common Lisp's `cl'.
5267 (AC_PROG_CXX): Behave according to the documentation: don't
5268 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5269 make the variable CCC precious; use `cl.exe', not `cl'.
5271 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5272 Alexandre Duret-Lutz <adl@gnu.org>
5274 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5275 /dev/null, as "configure" shouldn't read stdin, and this insulates
5276 us from problems (e.g., when testing for "cl"). Also, do this
5277 redirection before invoking "hostname" or "uname", and keep the
5278 original input stream available via...
5279 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5280 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5281 bother with "</dev/null" since it's now done at the top of
5282 'configure'.
5283 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5284 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5285 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5286 * doc/autoconf.texi (File Descriptor Macros): New section.
5287 (Printing Messages): Mention it.
5288 * tests/base.at (Input/Output): New test.
5290 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5292 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5293 newline if neither \c nor -n work, as that would output two
5294 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5296 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5298 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5299 This causes that any required macros inside will get before the if.
5300 * doc/autoconf.texi (autom4te.cache): A typo.
5302 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5304 Undo previous change, except keep the change to
5305 lib/autoconf/programs.m4 that replaced grep with shell
5306 pattern-matching. This is because net-snmp configure reads stdin.
5307 Reported by Noah Misch.
5309 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5311 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5312 from /dev/null, as "configure" shouldn't read stdin, and this
5313 insulates us from problems (e.g., when testing for "cl").
5314 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5315 before invoking "hostname" or "uname".
5316 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5317 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5318 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5319 "</dev/null" since it's now done at the top of 'configure'.
5320 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5321 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5322 Also, replace grep with shell pattern-matching, to save a process.
5324 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5326 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5327 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5328 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5329 compiler.
5331 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5333 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5334 grep -q isn't portable. Improve grep -s explanation.
5335 Problem reported by Dan Manthey.
5337 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5339 * doc/autoconf.texi (Special Shell Variables): Clarify
5340 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5342 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5344 * doc/autoconf.texi: Use @acronym for DJGPP.
5345 Fix some @code's that should have been @env's, and vice versa.
5346 Sort environment variable names.
5347 Mention that shells no longer inherit IFS.
5348 Don't recommend PATH_SEPARATOR=';' so strongly.
5349 Mention that $RANDOM might expand to the empty string.
5350 "symlink" and "soft link" -> "symbolic link".
5351 Improve mktemp description (reported by Bruno Haible).
5353 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5355 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5356 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5357 Likewise.
5358 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5359 Likewise.
5361 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5363 * NEWS: Mention AT_COPYRIGHT.
5365 * tests/local.at (AT_CMP): Use diff directly on input files rather
5366 than copying them.
5368 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5369 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5371 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5372 and Paul Eggert <eggert@cs.ucla.edu>
5374 * tests/autotest.at (Empty test suite): New test.
5375 * tests/torture.at (Substitute and define special characters)
5376 (Substitute a 2000-byte string, Define to a 2000-byte string)
5377 (Substitute a newline, Define a newline): New tests.
5379 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5381 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5382 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5383 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5384 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5385 (Standard regular expressions): New test.
5386 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5387 excess test name quoting.
5388 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5389 CPPFLAGS to `configure' instead of setting it in `configure'.
5391 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5392 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5393 on some platforms.
5395 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5396 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
5398 * tests/local.at (AT_CMP): New macro.
5399 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
5400 (AC_SAVE_STATE): Move environment grep...
5401 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
5402 (AT_CONFIG_CMP): New macro.
5403 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
5404 * tests/c.at (Extensions): Do not exit early.
5405 * tests/atlocal.in: Inherit $GREP.
5407 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
5408 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
5410 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
5411 (AC_COPYRIGHT): Factor header comment portion out and move into...
5412 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
5413 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
5414 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
5415 --version output.
5416 * tests/local.at: Add Autoconf test suite copyright notice.
5417 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
5419 2005-02-04 Bruno Haible <bruno@clisp.org>
5420 and Paul Eggert <eggert@cs.ucla.edu>
5422 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
5424 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
5426 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5427 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5429 Try not to generated lines of unlimited length, as POSIX places a
5430 2047-byte limit on line length of portable text files.

5490 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5491 Update the long comment explaining it.
5493 m4_require no longer writes an ``is required by'' line to the
5494 execution stack. It contains only one bit of non-redundant
5495 information: that the macro was required, not called. And even
5496 this bit is useless in most situations: have you ever met a macro
5497 which both calls and requires the same macro?
5499 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5500 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5508 * tests/m4sugar.at (m4_require): Expect output without the
5509 ``is required by'' messages.
5511 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5513 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5514 rather than x for expr.

5517 this is safe.
5518 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

5545 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5547 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5548 Warn about newline stripping in `` and $(). Update Solaris
5549 version to 9.

5577 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5579 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5602 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
5603 otherwise.
5604 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5605 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5606 stored in _m4_divert_diversion or _m4_divert_dump.
5607 (m4_divert_pop): When the parameter is given, compare the symbolic
5608 name with the last diversion pushed on the stack. Previously, the
5609 current diversion was compared with the numeric value of the
5610 diversion given as the parameter.
5611 (m4_require): If the macro hasn't been expanded yet, call ...
5612 (_m4_require_call): this new macro.

5645 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

5698 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
5699 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

5893 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
5894 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5895 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
5896 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
5898 2004-12-07 Stepan Kasal <kasal@ucw.cz>
5900 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous
5901 patch: extra "-l"s.
5903 2004-12-06 Paul Eggert <eggert@cs.ucla.edu>
5905 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
5906 looking elsewhere for getmntent. Problem reported by Mark D. Baushke.
5907 * doc/autoconf.texi (Particular Functions): Mention new behavior.
5909 2004-12-03 Stepan Kasal <kasal@ucw.cz>
5911 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
5912 out the common code to ...
5913 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
5914 value of the #define--default to 1, iff the macro was called
5915 with exactly one parameter.
5917 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5919 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5920 "char c = '\200';" rather than "char c = 0x80;" as the
5921 latter doesn't conform to the strict C standard due to
5922 overflow on signed char hosts.
5924 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5925 to -qlanglvl=ansi. We don't want to disable extensions.
5927 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
5929 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
5930 (Using Autotest, testsuite Scripts, Writing testsuite.at):
5931 Reword slightly to avoid some English-language problems noted

5943 along with some nearby cruft.
5944 * doc/autoconf.texi (Libtool): Libtool can be used without
5945 Automake (not without Autoconf).
5946 (Introduction): Mention lists.gnu.org.
5947 * BUGS: Don't mention bugs.gnu.org.
5948 Remove mention of ancient libtool compatibility problem.
5949 * NEWS: Mention that bugs.gnu.org is kaput.
5950 * README: Likewise. Mention where mailing list archives can be found.
5952 2004-11-28 Stepan Kasal <kasal@ucw.cz>
5954 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): A typo in the comment.

5972 in my editing of the previous patch. Problem reported
5973 by Alexandre Duret-Lutz.
5975 2004-11-22 Stepan Kasal <kasal@ucw.cz>
5977 * doc/autoconf.texi (Autoconf Language): Explain that
5978 ``descriptions'' may not be double quotes.
5979 (Quotation Rule Of Thumb): Likewise.
5980 (Pretty Help Strings): Likewise; remove the wrong comment;
5981 simplify the examples and improve their quoting.
5983 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5985 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5986 the $1_found variable, don't test whether the file is executable;
5987 Both things are checked ...
5988 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
5989 the former ``test -f''.
5990 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
5992 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
5994 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
5995 use cp -R instead.
5997 2004-11-10 Derek R. Price <derek@ximbiot.com>
5999 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
6000 limitations. Reorder paragraphs for clarity.
6002 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
6004 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
6005 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
6006 variants", "Unix", and some related minor wording fixups.
6008 (Shellology, Special Shell Variables): Document that the Zsh
6009 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
6010 to Alexandre Duret-Lutz for this info.

6019 of putenv. Problem reported by Michael Wardle.
6021 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
6023 * doc/autoconf.texi (auindex): New macro.
6024 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
6025 Problem reported by Stepan Kasal.
6027 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
6029 Fix problems reported by Andreas Buening in:
6030 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
6031 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
6032 in test makefile.
6033 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
6034 readable; it's not true in OS/2-emx.
6036 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
6038 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
6039 "/usr/include", clear ac_x_includes instead of leaving it as "no"
6040 (trivial change). Problem and patch reported by Andrew Church in:
6041 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
6043 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
6045 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
6046 three args in examples. Problem reported by Frederik Fouvry in:
6047 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
6048 Also, fix some minor spacing and punctuation bugs.
6050 2004-09-02 Akim Demaille <akim@epita.fr>
6052 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
6053 "case" to restore ordering.
6054 Reported by Stepan Kasal.
6056 2004-08-26 Akim Demaille <akim@epita.fr>
6058 * doc/autoconf.texi: Minor typos and stylos.
6060 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
6062 * configure.ac (AC_INIT): Bump to 2.59c.
6064 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
6066 Version 2.59b.
6068 * README: Add advice about m4 1.4.2.
6070 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
6071 texinfo.tex for now (done by hand now).
6072 * Makefile.maint (wget_files, cvs_files):
6073 Remove ansi2knr.c; nobody uses it.
6074 (ansi2knr.c-url_prefix): Remove.
6075 (cvs-update): Fix test for failure. I don't know why it ever
6076 worked...
6078 * doc/autoconf.texi: Update URLs, some of which went stale.
6079 Use @uref rather than @href.
6081 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
6082 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
6084 * config/config.guess, config/config.sub, config/elisp-comp,
6085 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
6086 doc/fdl.texi, doc/standards.texi: Sync with master copy.
6088 * NEWS, TODO, configure.ac, bin/autoscan.in,
6089 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
6090 doc/install.texi, lib/Autom4te/Configure_ac.pm,
6091 lib/Autom4te/FileUtils.pm, lib/autoconf/general.m4,
6092 lib/autoconf/programs.m4, lib/autoconf/status.m4,

6094 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
6095 tests/tools.at, tests/torture.at:
6096 Use "file name" rather than "filename" or "path",
6097 to be consistent with the terminology of the GNU coding standards.
6099 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
6101 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
6102 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
6103 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
6104 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
6106 More fixes to support spaces in the name of the build directory.
6107 This isn't a complete fix but it's an improvement.
6109 * bin/autoconf.as (autom4te_options): New var.
6110 Use it instead of appending to AUTOM4TE, so that we can allow
6111 spaces in the build directory's absolute name.
6112 * bin/autoheader.in ($autoconf): Allow spaces in file names.
6113 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
6114 AT_CHECK_NOESCAPE): Likewise.
6115 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
6116 main program): Likewise.
6118 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
6120 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
6121 From Ralf Corsepius in:
6122 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
6124 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
6126 * doc/autoconf.texi (Function Portability): Document isinf and
6127 and isnan. From a suggestion by Kevin Ryde.
6129 * lib/Autom4te/General.pm (END): Return correct exit status even
6130 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
6132 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
6134 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6135 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6136 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
6138 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6140 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
6141 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
6142 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
6143 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
6144 * lib/autom4te.in (Automake-preselections): Preselect
6145 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6147 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6149 * lib/autom4te.in (Automake-preselections): Preselect
6150 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6151 trace them.
6153 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6155 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6156 Tru64.
6157 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6158 Document problem with "`""`" in pdksh POSIX mode.
6160 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6162 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6163 with pdksh, too. Problem reported by Patrick Welche via
6164 Gary V. Vaughan.
6165 * doc/autoconf.texi (Shellology): Note that set -o posix is
6166 useful for pkdsh, too.
6168 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6170 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6171 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6172 Don't fail if ENV or BASH_ENV is readonly.
6173 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6174 etc. are read only. Problem reported by Ludovic Courtes.
6176 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6178 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6179 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6180 (trivial change)
6182 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6184 * doc/autoconf.texi (File System Conventions): Warn about
6185 names like "aux". Problem reported by Eric Blake.
6187 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6188 by zero instead of array size, so that we can use any arithmetic
6189 constant expression (instead of requiring an integer constant
6190 expression). This allows us to test expressions like DBL_MAX <
6191 LDBL_MAX, which didn't conform to the C standard using the old
6192 method.
6193 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6194 now that we can do floating-point tests at compile time.
6196 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6198 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6199 and LDBL_EPSILON, as the resulting expression isn't an
6200 integer constant expression and violates the C standard.
6201 Problem reported by Nelson H. F. Beebe. Also, check
6202 for "L" suffix, and check that long double doesn't have
6203 worse range or precision than double, that mixed-mode
6204 arithmetic doesn't generate a diagnostic, that double
6205 constants fit in long double.
6207 2004-06-03 Kevin Ryde <user42@zip.com.au>
6209 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6210 malloc(0) and realloc(NULL,size).
6212 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6213 Bob Proulx.
6215 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6217 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6218 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6219 by Jim Meyering.
6221 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6223 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6224 can be rewritten using if-then-else. Suggested by Bruno Haible.
6226 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6228 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6229 Problem reported by Stepan Kasal.
6231 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6233 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6234 change). Patch reported by Ralf Wildenhues in
6235 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6237 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6238 function F exists if the compiler and linker let you compile an
6239 expression like (F != 0). Recent versions of GCC optimize away
6240 the reference to F in that case, since every function address must
6241 be nonzero, so the link succeeds even if F does not exist.
6242 Problem reported by Manu in
6243 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6245 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6246 "Unix". Many uses changed.
6247 (Limitations of Builtins): Explain better why the ! command isn't
6248 portable.
6250 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6252 * lib/autom4te.in (Automake-preselections): Preselect
6253 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6255 2004-05-19 Kevin Ryde <user42@zip.com.au>
6257 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6258 referencing AC_FUNC_STRERROR_R.
6260 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6261 note pessimistic assumption when cross compiling.
6263 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6265 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6266 (until 2004) invoked subcommands with sh -e, contra POSIX.
6267 Reported by Kevin Ryde.
6269 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6271 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6272 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6273 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6274 `test -f " /usr/bin/grep"', which _always_ failed.
6275 (AC_PROG_SED): Ditto bogus PATH fix.
6276 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6277 requires that grep correctly supports _multiple_ `-e' options, rather
6278 than stating only that grep should accept `-e'.
6280 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6282 Port to C99, which requires that 'exit' be declared.
6284 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6285 to ensure that stdlib.h is included.
6286 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6287 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6288 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6289 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6290 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6291 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6292 when using 'exit' in a test; C99 requires that 'exit' be declared.
6294 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6296 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6297 now prefers 'grep' implementations that accept -e.
6298 (Limitations of Usual Tools): Describe problems of traditional
6299 egrep and fgrep with long input lines, and of traditional grep
6300 with -e.
6301 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6302 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6303 All callers changed. Append /usr/xpg4/bin to the PATH, for
6304 Solaris.
6305 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6306 the user with complaints about multiple -e options.
6307 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6308 Define it with AC_PROG_GREP.
6309 * configure.ac (AC_PROG_GREP): Add.
6310 * lib/freeze.mk (GREP): New macro.
6312 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6314 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6315 a possible candidate only after all others fail, rather than
6316 consulting it first. This improves backward compatibility by
6317 better reflecting the way shell selection occurred in previous
6318 versions of Autoconf, and should help to avoid triggering latent
6319 problems in other packages, such as the one in Automake where zsh
6320 is not handled robustly:
6321 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6322 Although it is not Autoconf's responsibility to work around
6323 problems in Automake, it nevertheless makes sense to avoid
6324 introducing unnecessary incompatibilites.
6326 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6327 Gary V. Vaughan <gary@gnu.org>
6329 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6330 how deeply nested we are when a suitable tool is found, set the
6331 ac_path_TOOL_found flag.
6332 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6333 nested we are in this macro. Break out of all 3 nested loops if
6334 ac_path_TOOL_found is set.
6336 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6338 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6339 of the _AS_PATH_WALK loop too if GNU flavor is found.
6341 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6343 * doc/autoconf.texi (Limitations of Make): Update documentation
6344 for `$<'. New entry `Long lines', based on a report from Simon
6345 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6346 paragraph about DJGPP, based on a mail from Richard Dawe.
6348 2004-04-20 Paul Eggert <eggert@twinsun.com>
6350 * tests/c.at (C keywords): Don't assume that GCC supports
6351 "restrict" and "inline", as sufficiently-old GCC versions do not
6352 (also, GCC configured to be in pedantic C89 mode does not).
6353 Problem reported by Sumit Pandya in:
6354 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6356 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6357 consider -g to work if it generates warnings when plain compiles
6358 don't. Problem reported by Braden McDaniel in:
6359 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6361 * doc/autoconf.texi (Slashes): New section, to document a problem
6362 reported by Jim Meyering in:

6370 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6372 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6373 best tool so far counter rely on the tool path variable name to
6374 avoid checks for one tool being affected by the results of running
6375 the length check on a previous tool.
6377 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6378 match expression argument, as different greps have different
6379 regular expression flavours.
6380 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6381 literals.
6382 (AC_PROG_EGREP): Pass 'EGREP$'.
6383 (AC_PROG_GREP): Pass 'GREP$'.
6385 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6387 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6388 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

6392 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6393 Types, Specific Compiler Characteristics, System Services,
6394 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6395 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6396 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6397 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6398 Likewise.
6399 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
6400 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,

6408 2004-03-28 Paul Eggert <eggert@twinsun.com>
6410 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6411 now defines HAVE_DECL_TZNAME if it is declared, when
6412 HAVE_STRUCT_TM_TM_ZONE is not defined.
6413 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6414 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6415 for HAVE_TZNAME.
6417 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
6419 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected

6427 H. F. Beebe for the bug report.
6429 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6431 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6432 quoted -cmdline argument in Portland Group compiler (bug
6433 reported by Jeffrey J. Barteet).
6435 2004-03-25 Kevin Ryde <user42@zip.com.au>
6437 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
6438 (Run Time): ... here, where it's now mentioned.

6459 AC_CHECK_TOOLS.
6460 (Specifying Names): Document the reason for these future
6461 behavioral changes.
6462 * tests/mktests.sh: Do not generate tests for the
6463 new macros.
6464 * NEWS: Document these changes.
6466 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6467 they make TeX hang up.

6471 * NEWS: New macro AC_CHECK_ALIGNOF.
6472 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6473 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6474 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6475 vowel.

6481 2004-03-03 Paul Eggert <eggert@twinsun.com>
6483 * bin/Makefile.am (edit): Don't use $< in a context where
6484 POSIX doesn't require support for it. Use $@.in instead.
6485 Problem reported by Anthony N. Frasso in
6486 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6487 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
6489 2004-02-23 Gary V. Vaughan <gary@gnu.org>
6491 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
6492 from the next generation of Libtool.
6493 * lib/autom4te.in (Autoreconf-preselections): Ditto.
6495 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6497 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
6498 is not always thread-safe. Report from Nathanael Nerode.
6500 2004-02-18 Paul Eggert <eggert@twinsun.com>
6502 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6503 problem on QNX reported by Stephen Rasku in
6504 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6506 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6507 $(m4sh_m4f_dependencies); this removes a FIXME.
6508 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6509 (MAINTAINERCLEANFILES): Split into pieces,
6510 one per related section. Add $(srcdir)/wrapper.in.
6512 2004-02-09 Paul Eggert <eggert@twinsun.com>
6514 * doc/autoconf.texi (Setting Output Variables): Emphasize that
6515 AC_SUBST provides no portable way to escape literal newlines.
6517 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6518 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6519 Darwin uses -lcrt2.o and there's little point to cataloging all
6520 the system variants. Partial fix reported by Andreas Waechter in:
6521 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
6522 for bug reported by Nelson H. F. Beebe in:

6537 the behavior of the third argument.
6538 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6539 correctly the behavior of the third argument. Document
6540 what the three macros that AU_DEFUN defines do. Fix
6541 warning message when the third argument includes $0

6544 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6545 Eric Sunshine <sunshine@sunshineco.com>
6546 Paul Eggert <eggert@twinsun.com>
6548 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
6549 (AS_INIT): Output shell initialization there. Removed optional
6550 parameter. Expand _AS_SHELL_FN_SPY.
6551 (AS_INIT_WITH_SHELL_FN): Removed.
6552 (_AS_SHELL_FN_SPY): New macro.
6553 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
6554 macros.
6555 (AS_SHELL_SANITIZE): Remove loop to find better shell
6556 and documentation for the parameter.
6557 (_AS_DETECT_BETTER_SHELL): Move it here.

6560 (AS_REQUIRE_SHELL_FN): Require shell functions when
6561 it is used.
6562 (_AS_LINENO_WORKS): Put around braces, we do not
6563 trigger the bash bug anymore.
6564 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
6565 use AS_INIT_WITH_SHELL_FN.
6566 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6568 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6570 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
6571 * doc/autoconf.texi: Don't say that the third parameter
6572 is broken.
6573 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
6574 (AU_DEFUN): Honor the third parameter, create autoupdate
6575 macros with AU_DEFINE.
6576 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
6577 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
6578 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
6579 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
6580 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

6585 * lib/autoconf/status.m4: Remove FIXME.
6586 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
6587 that the macro is not present anymore in the updated
6588 configure.ac.

6596 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6597 2003 (except 1997) to the list of copyright years. This undoes
6598 the 2003-05-22 change, which removed the older years from the list.
6599 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6601 2004-01-27 Gary V. Vaughan <gary@gnu.org>
6602 Albert Chin-A-Young <china@thewrittenword.com>

6605 grep or ggrep program in PATH that accepts as long lines as
6606 possible.
6607 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
6608 AC_PROG_GREP.
6609 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
6610 egrep and fgrep respectively if $GREP -E/-F don't work.
6611 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6612 _AC_PROG_GREP, and AC_PROG_SED.
6613 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6614 longest input length accepted by a command.
6615 (AC_PROG_SED): Use it.
6616 * doc/autoconf.texi (Particular Programs): Document the changes.
6617 * NEWS: Updated.
6619 2004-01-27 Paul Eggert <eggert@twinsun.com>
6621 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

6626 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6627 bin/autoconf.in, config/Makefile.in, config/config.guess,

6641 sources.
6643 2004-01-26 Paul Eggert <eggert@twinsun.com>
6645 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6646 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6647 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6648 not <inttypes.h>. Problem reported by Tim Mooney in
6649 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6650 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6651 Likewise.
6653 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6654 otherwise "make check" fails because it forbids cmp (I guess
6655 because cmp treats files as binary on DOS-like systems).
6657 * tests/mktests.sh: Update copyright date to 2004, since some tests
6658 have changed in 2004.
6660 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6662 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6663 non-truncating sed or gsed program in PATH.
6664 * tests/acprograms.at: Add it.
6665 * doc/autoconf.texi (Particular Programs): Document it.
6666 * NEWS: Updated.
6668 2004-01-15 Paul Eggert <eggert@twinsun.com>
6670 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6671 -std1 disables some useful extensions on Tru64. Problem reported
6672 by N. Lichtmaier in
6673 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6675 2004-01-14 Paul Eggert <eggert@twinsun.com>
6677 * doc/autoconf.texi (Programming in M4sh): Document that
6678 AS_MKDIR_P succeeds if the destination is a symbolic link
6679 to an existing directory.
6680 (Limitations of Usual Tools): Note that mkdir -p might not
6681 succeed on symlinks to directories.
6683 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6685 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6686 * bin/autoheader.in: Grammar fix in message.
6687 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6688 Test for dir before calling mkdir -p. (trivial changes)
6690 2004-01-13 Eric Blake <ebb9@byu.net>
6692 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6693 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6695 2004-01-10 Jim Meyering <jim@meyering.net>
6697 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6699 2004-01-09 Paul Eggert <eggert@twinsun.com>
6701 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6702 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6703 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6704 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6705 AC_COMPILE_IFELSE, since we now assume our caller invokes
6706 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6707 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6708 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6709 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6711 2004-01-07 Paul Eggert <eggert@twinsun.com>
6713 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6714 `"'...'"`, as it's confusing (and I suspect it may not work on
6715 some platforms). The code was incorrect anyway, as it assumed
6716 that \$ evaluated to itself in that context. Reported by
6717 Alexandre Duret-Lutz.
6719 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6721 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6722 and _LT_AC_TAGCONFIG.
6724 2004-01-06 Paul Eggert <eggert@twinsun.com>
6726 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6727 example, and add more examples. Reported by Eric Sunshine.
6729 2004-01-05 Paul Eggert <eggert@twinsun.com>
6731 * doc/autoconf.texi (Limitations of Usual Tools):
6732 Remove warning against "rm -fr" introduced yesterday; it
6733 was a false alarm.
6735 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6736 autoscan, autoupdate, ifnames): Don't use chmod -w.
6737 * lib/Makefile.am (autom4te.cfg): Likewise.
6738 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6739 "chmod -w".

6742 Paolo Bonzini <bonzini@gnu.org>
6744 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6745 by doing lineno substitution only on lines containing "$LINENO".
6747 2004-01-04 Paul Eggert <eggert@twinsun.com>
6749 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6750 Use "rm -f" to remove conftest.sed, not plain "rm".
6751 Bug reported by David Relson in
6752 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6754 * Makefile.am (autom4te-update):
6755 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6756 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6757 * doc/autoconf.texi (Guidelines): Likewise.

6764 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6765 srcdir): Likewise.
6766 * doc/autoconf.texi (Limitations of Usual Tools):
6767 Warn against "rm -fr".
6769 2004-01-03 Paul Eggert <eggert@twinsun.com>
6771 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6772 -c -o might not work. From a suggestion by Kevin Ryde.
6773 (C Compiler, Generating Sources, Limitations
6774 of Usual Tools, Limitations of Make, Making testsuite Scripts):

6843 * config/announce-gen (&print_locations, &print_signatures)
6844 (&sizes): New.
6845 Use them.

6847 them on the fly.
6849 2003-11-24 Akim Demaille <akim@epita.fr>
6851 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6894 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6895 than $target since the latter is not usual, add guidelines on when to

7055 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
7056 cross test.
7058 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
7060 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
7061 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

7073 Problems reported by Eric Sunshine.
7075 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7077 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7078 -mGLOB_options_string stuff for Intel ifc, which can cause

7102 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7103 cache variable instead of $G77 to decide whether to include -O2,
7104 since $G77 is specific to Fortran 77.
7106 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7108 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

7113 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7114 arguments so that it can be used with syntax identical to
7115 AC_PROG_F77, and so that we can more easily decide to
7116 remove/deprecate the DIALECT optional argument in the future if it
7117 proves troublesome.
7118 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7119 non-freeform-supporting compilers. Document freeform flags.
7121 2003-10-03 Akim Demaille <akim@epita.fr>
7123 * configure.ac: Look for emacs, not macs.
7124 Reported by Eric Sunshine.
7126 2003-10-03 Akim Demaille <akim@epita.fr>

7133 2003-10-03 Akim Demaille <akim@epita.fr>
7135 * configure.ac: Quotation and formatting changes.

7170 have been created when invoking the compiler.

7184 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7185 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7186 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7188 2003-09-26 Akim Demaille <akim@epita.fr>
7190 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7191 directory for AC_CONFIG_COMMANDS' first argument exists.
7192 This makes valid the invocation of _AC_SRCPATH that follows.
7193 Reported by Eric Sunshine.
7194 * doc/autoconf.texi (Configuration Commands): Adjust.
7196 2003-09-26 Akim Demaille <akim@epita.fr>
7198 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7199 Reported by Ralf Corsepius.

7203 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
7204 arguments.

7215 2003-09-26 Akim Demaille <akim@epita.fr>
7217 The test suite are sometimes assigning timings incorrectly.
7218 Reported by Henk Krus.
7219 Diagnosed by Nicolas Joly.
7221 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7222 AT_help_all.
7223 Instead of making AT_help a sequence of assignments to grow
7224 $at_help_all, just make AT_help_all be the growing contents of
7225 $at_help_all, and make a single assignment in...
7226 (AT_INIT): here.
7227 (at_times_skip): Flip the meaning and rename as...
7228 (at_times_p): this.
7229 (AT_INIT): When summarizing the test that ran, remove
7230 $at_times_file after use, and check it is present before trying to
7231 use it.

7239 (ifnames): chmod -w.
7240 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7241 executables, not bin/ executables! Otherwise all the magic needed
7242 to find non installed files is turned off. This caused a failure
7243 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7244 as found in its environment (sent by tests/autoreconf): pointing
7245 to bin/autom4te that could not find its files.
7246 * tests/mktests.sh: Force the replacement of generated files, for
7247 the sake of "mv" program that are interactive when overwriting a
7248 -w file.

7259 Trivial change to support GCC's configuration procedure.
7260 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
7261 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
7262 about inconsistency if the preprocessor is set to give errors for
7263 any warning.
7264 * doc/autoconf.texi (C Compiler Characteristics): Document this.

7346 correspond to all the old F77 macros, with output variables FC,
7347 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7348 available dialect, but older dialects can be specified. There are
7349 new macros AC_FC_SRCEXT to set the source extension, and
7350 AC_FC_FREEFORM to accept free-form source files.

7388 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7389 are defaulted by AT_CHECK anyway.

7391 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7392 missing dnl.

7460 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7461 (&verbose): Remove.
7462 (&getopt): Adjust the note and verb channels, depending upon

7476 2003-08-21 Akim Demaille <akim@epita.fr>
7478 First stab at preserving warnings between calls to autom4te,
7479 including when the cache is used.
7481 There are still several issues: (i) there are too many runs of m4
7482 (one for include, one for warnings, and some more), (ii) warnings
7483 spreading on several lines are not handled gracefully, (iii) the
7484 code meant to have the call stack display for errors does not work
7485 (its handling should move from m4 to autom4te).
7487 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7488 Use them.
7489 (@preselect): Add m4_warn.
7490 ($exit_status): Remove, use $exit_code.
7491 ($help): Use Autom4te::ChannelDefs::usage.
7492 (&handle_m4): No longer define the m4_warnings.
7493 At each run, extract and report the warnings.
7494 Always cache the result, including if the exit status is on
7495 failure, since if nothing changes, we should result in the same
7496 failure, hence we can use the cache.
7497 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7498 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7499 Remove.
7500 (m4_warn): Redefine as a do-nothing: it is its invocation that
7501 matters, as warnings are now reported via traces.
7502 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7503 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7504 the latter reveals calls to the former.
7506 Adjust the tests.
7508 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7510 2003-08-21 Akim Demaille <akim@epita.fr>
7512 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7513 Use them.
7515 2003-08-21 Akim Demaille <akim@epita.fr>
7517 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7518 forward order.
7519 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7520 (&parse_warnings): Accept a list of warning requests.
7521 (&usage): Return a string, not a side effect.
7522 (cross): New warning category.
7524 2003-08-21 Akim Demaille <akim@epita.fr>
7526 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7527 (&require_configure_ac): Accept an optional directory argument.
7528 ($configure_ac): Remove.
7529 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7530 (&catfile): Remove.
7531 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7532 * bin/autoscan.in: Adjust.
7534 2003-08-20 Akim Demaille <akim@epita.fr>
7536 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7537 Reported by Alexandre Duret-Lutz.
7539 2003-08-20 Akim Demaille <akim@epita.fr>
7541 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7542 * bin/autom4te: Adjust.
7543 In particular, be Autoconf tools are really silent when properly
7544 working, bind the verbosity of the 'note' channel to $verbose.
7545 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7546 (&xsystem, &contents): Remove, since they are exported by...
7547 * lib/Autom4te/FileUtils.pm: this.
7548 More perldoc.
7549 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7550 * lib/Autom4te/FileUtils.pm: here.
7552 2003-08-20 Akim Demaille <akim@epita.fr>
7554 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7555 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

7580 * lib/autom4te.in (Automake-preselections): Preselect
7581 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
7582 and m4_sinclude.
7584 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7586 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

7607 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7608 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7609 shorter column three. Add DESCRIPTION to log file content.
7611 2003-08-13 Derek Price <derek@ximbiot.com>
7613 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7614 output.

7625 (AT_CHECK_NOESCAPE): ...to this new macro.
7627 2003-07-31 Paul Eggert <eggert@twinsun.com>
7629 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7630 in Bash 2.01. Problem reported by Brian Gough in
7631 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

7641 inside '#ifndef __cplusplus'. Problem reported by
7642 Bob Friesenhahn.
7644 2003-07-06 Bill Clarke <llib@computer.org>
7646 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7647 'long', not 'int', for benefit of Sun's recent C++ compilers
7648 (trivial change). See:
7649 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7650 (This really should be 'intptr_t', not 'long', but that would
7651 take more work.)
7653 2003-06-25 Akim Demaille <akim@epita.fr>
7655 * lib/Makefile.am (autom4te.cfg): Make it read only.
7656 Depend on Makefile since it contains substitutions.

7665 From Gareth McCaughan.
7667 2003-06-23 Akim Demaille <akim@epita.fr>
7669 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7670 not all of them. This fixes 1. the fact that when testing
7671 Autoconf there are many many config.log, 2. the incorrect use of
7672 top_srcdir to find config.log.
7673 Don't mix the detailed output of failed test with the summary of
7674 failures. Rather, append detailed log afterwards.
7676 2003-06-23 Akim Demaille <akim@epita.fr>
7678 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7679 always run: output config.log on $at_group_log.

7750 * NEWS, doc/autoconf.texi (Particular Functions),
7751 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7752 is the inverse of localtime.
7754 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7756 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7757 (handle_exec_errors): New function. Work around $! being
7758 altered by WEXITSTATUS.
7759 (xqx, xsystem): Use handle_exec_errors.
7761 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7763 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7764 Do not call `_exit()', simply modify `$?'.
7765 (xsystem): Reset $! before running system, and check it afterward.
7766 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7767 63 for version mismatches.
7769 2003-05-23 Akim Demaille <akim@epita.fr>
7771 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7772 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7773 the middle of a line).
7774 * lib/m4sugar/m4sugar.m4: Likewise.
7775 Remove useless spaces in comments.
7777 2003-05-23 Akim Demaille <akim@epita.fr>
7779 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7780 exit 63, so that we (or Automake's "missing") can tell the
7781 difference with a plain failure.
7782 * doc/autoconf.texi (Notices): Adjust.
7784 2003-05-23 Akim Demaille <akim@epita.fr>
7786 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7787 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7788 White spaces cleanup.
7790 2003-05-22 Jim Meyering <jim@meyering.net>
7791 Paul Eggert <eggert@twinsun.com>
7793 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7794 Remove `#include <stdlib.h>' from the list; we should never
7795 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7796 resulting namespace pollution would cause other tests to fail.
7797 Configure scripts run with some older versions of g++ and HP's
7798 aCC would fail due to such an #include. Problems reported by
7799 Matthew Mueller in <http://bugs.debian.org/120704> and by
7800 Keith Bostic in
7801 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7802 In the test, use the test declaration before including <stdlib.h>,
7803 as that's closer to how it'll be used.
7805 2003-05-23 Akim Demaille <akim@epita.fr>
7807 * doc/autoconf.texi (Header Portability): ucred.h.
7808 From Ian Redfern.
7810 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7812 Overhaul Autotest's logging: generate separate log files
7813 in testsuite.dir/NNN/testsuite.log, and append them to
7814 testsuite.log instead of re-running the test verbosely.
7816 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7817 file descriptor, write 0 to at_status_file instead of setting
7818 at_status=0, initialize some new variables (at_status_file,
7819 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7820 to rerun the tests, instead append the at_group_log to the
7821 at_suite_log when a test fails.
7822 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7823 with the AS_MESSAGE_LOG_FD redirected to stdout.
7824 (AT_CLEANUP): save the output status in $at_status_file
7825 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7826 its original place.
7827 (AT_CHECK): since tests are run with a redirected stdout,
7828 and used to be re-run in verbose mode, turn some $at_verbose
7829 into echo, and don't redirect the output of testing stdout
7830 and stderr.
7832 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7833 the name of the debugging directory and information about
7834 its contents.
7836 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7838 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7839 parameter.

7909 Reported by Sander Niemeijer.
7910 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

7951 and truncate.
7953 2003-05-06 Akim Demaille <akim@epita.fr>
7955 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7956 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7957 by aclocal.m4 is changed it might require the importing of another
7958 m4 extension file, i.e., aclocal must be run.
7960 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7961 (&parse_args): Use --force with aclocal if required and supported.
7962 (&autoreconf_current_directory): Use &run_aclocal.

7969 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7970 argument instead of a file name, so that the request file remains
7971 open during the whole autom4te run.
7972 ($icache_file): New.
7973 (&freeze): Lock the $icache_file.
7975 2003-04-29 Derek Price <derek@ximbiot.com>
7977 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7978 seperator with m4_append_uniq(). It doesn't work.
7979 (AT_CLEANUP): Add `;' to end of at_help_all.
7980 (AT_INIT): Allow --keywords to be specified more than once. When
7981 grepping $at_help_all for keywords, use the field and keyword
7982 seperators to ensure a complete keyword match. Alter at_prev handling
7983 to support the new --keywords behavior.
7985 2003-04-27 Karl Berry <karl@freefriends.org>
7987 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7988 align better with others. I also made some of the individual
7989 entries on one line, for brevity and to make it easier for me to
7990 sort my dir-example file in the Texinfo distribution :).
7992 2003-04-12 Jim Meyering <jim@meyering.net>
7994 * NEWS: Mention the new macro.

8035 2003-03-31 Derek Price <derek@ximbiot.com>
8037 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
8038 which removed the main loop.
8039 Thanks to Akim Demaille.
8041 2003-03-29 Akim Demaille <akim@epita.fr>

8044 that starts a GUI.
8045 From Ilya Zakharevich.
8047 2003-03-29 Akim Demaille <akim@epita.fr>

8053 2003-03-28 Akim Demaille <akim@epita.fr>
8055 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest

8057 header causes problems.
8059 2003-03-28 Akim Demaille <akim@epita.fr>
8061 * tests/torture.at (Configuring subdirectories): Require aclocal
8062 1.4, otherwise the test fails, as it does support configure.ac.
8063 This fixes the "test 40 failed" bug reports.
8065 2003-03-28 Akim Demaille <akim@epita.fr>
8067 * doc/autoconf.texi (C Compiler): `#line' portability.

8135 Tru64 make in the "target lookup" section.
8136 (Automake): Automake 1.5+ no longer requires special tools to be
8137 present on the developer's host.

8155 ${ac_make}.
8157 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
8158 When constructing paths with IFS=:, quote the path. If we're

8177 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
8178 to fix a mismatch between example and discussion.
8180 2003-02-24 Kevin Ryde <user42@zip.com.au>
8182 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8183 format starting with "-".
8185 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8187 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8188 is not portable inside Makefile.
8190 2003-02-20 Akim Demaille <akim@epita.fr>
8192 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8193 compiler says yeah, but preproc says nope, compiler is right.
8194 Conversely, prompt the reader to send a bug report to the
8195 maintainers of the package, not of Autoconf.
8197 2003-02-20 Klee Dienes <kdienes@apple.com>
8199 * bin/autoreconf.in (autoreconf_current_directory): Properly

8210 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8211 innocuous variant befor including <limits.h> or <assert.h>. This
8212 works around a bug reported by Albert Chin: HP-UX 11i
8213 (and earlier versions) have a <limits.h> that declares
8214 gettimeofday and many other functions.
8216 2002-12-03 Paul Eggert <eggert@twinsun.com>
8218 Version 2.57.
8220 * NEWS, configure.ac: Update version.

8224 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8225 nontrivially in main's body, so that f's external declaration is
8226 not optimized away in AIX. This should fix the bug reported by
8227 Martin Frydl in
8228 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8230 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8231 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8232 defined, to support freestanding compilers. This should fix the
8233 bug reported by Momchil Velkov in
8234 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8236 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8237 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
8238 obsolete AC_CHECK_TYPE. The missing empty arg was reported
8239 by Simon Josefsson in
8240 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
8242 * Makefile.maint (www-gnu): New macro.
8243 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
8244 the location has moved.
8246 2002-12-02 Martin Frydl <martin@systinet.com>
8248 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
8249 \(.*\) match is too long and there is something more to be checked.
8250 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
8252 2002-11-15 Akim Demaille <akim@epita.fr>

8268 Update from masters.
8270 2002-11-14 Akim Demaille <akim@epita.fr>
8272 * Makefile.maint: Sync with Bison, i.e.:
8273 (po-check): Scan .l and .y files instead of the
8274 .c and the .h files that they generate. This fixes the bug
8275 reported by Tim Van Holder in:
8276 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8277 Look for N_ as well as for _. Try to avoid matching #define for
8278 N_ and _.
8279 From Paul Eggert.
8281 2002-11-14 Akim Demaille <akim@epita.fr>
8283 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8284 From Paul Eggert and Albert Chin-A-Young.
8286 2002-11-14 Akim Demaille <akim@epita.fr>
8288 * doc/autoconf.texi (C Compiler): Solitary backslashes.
8289 From Paul Eggert and Albert Chin-A-Young.
8291 2002-11-14 Kevin Ryde <user42@zip.com.au>
8293 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8294 than assigning in main, to avoid HP cc +O3 optimizing it away.
8296 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8298 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8299 option. Process --recheck after parsing all options. Pass -q
8300 option to configure on --recheck.
8301 (AC_OUTPUT): Pass -q from configure to config.status.
8302 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8303 arguments to record.
8304 * doc/autoconf.texi (config.status Invocation): Document
8305 config.status -q option.
8307 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
8309 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
8310 Makefile.in if Makefile.am exists.

8321 2002-11-06 Akim Demaille <akim@epita.fr>
8323 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
8324 declaration in extern "C" too.
8325 Reported by Roberto Bagnara.

8329 * tests/torture.at (Configuring subdirectories): Don't use grep
8330 -w.
8331 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
8332 Reported by Ezra Peisach.
8334 2002-11-05 Akim Demaille <akim@epita.fr>
8336 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8337 Remove.
8338 We _have_ to stop using the old compatibility scheme that tried to
8339 avoid useless backslashes because Libtool 1.4.3 contains a
8340 AC_DEFINE([error_t], [int],
8341 [Define to a type to use for \`error_t' if it is not
8342 otherwise available.])
8343 We _have_ to quote the single quote and backslashes with \. The
8344 old compatibility scheme saw that ` was backslashed, and therefore
8345 did not quote the single quote. Hence before this patch, Autoconf
8346 was not compatible with Libtool.
8348 2002-11-04 Paul Eggert <eggert@twinsun.com>
8350 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8360 New.
8361 * config/texinfo.tex: Update.
8363 2002-11-03 Akim Demaille <akim@epita.fr>

8366 from...
8367 (&autoreconf): here.
8368 ($help, $make, &parse_args, &autoreconf_current_directory):
8369 Support -m/--make.
8370 * doc/autoconf.texi (autoreconf Invocation): Adjust.

8388 2002-10-31 Akim Demaille <akim@epita.fr>
8390 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
8391 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8392 Make variable, not a shell variable.
8393 Suggested by Bruno Haible.
8395 2002-10-31 Akim Demaille <akim@epita.fr>
8397 * bin/autom4te.in (load_configuration): Reject #args out of any
8398 language.
8400 2002-10-31 Akim Demaille <akim@epita.fr>

8414 Suggested by Tim van Holder.

8418 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
8419 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
8420 Problem reported by Bruno Haible.
8422 2002-10-29 Akim Demaille <akim@epita.fr>
8424 * doc/autoconf.texi (Header Templates): Put also in words what the

8426 (Customizing autom4te): s/--cache=/--cache /.
8428 2002-10-29 Akim Demaille <akim@epita.fr>

8731 (ansi2knr.c-url_prefix): Remove.
8733 2002-10-16 Akim Demaille <akim@epita.fr>
8735 Because of caching, some files that no longer exist and are no
8736 longer required can still cause errors.
8737 Reported by Alexandre Duret-Lutz.
8739 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8740 to frozen files in @ARGV, as @ARGV must remain being a list of
8741 files. Rather, at M4 call sites, use this...
8742 (&files_to_options): New function.
8743 (&freeze): Use &error.
8744 (&up_to_date): If a file that was included according to the cache
8745 is no longer there, then the output is out dated.
8746 (&main): Don't even check whether a file is up to date is anyway
8747 --force is given.
8748 * tests/tools.at (autom4te cache): New.
8750 2002-10-16 Akim Demaille <akim@epita.fr>
8752 * bin/autoconf.as: Kill dead options.
8753 * bin/autoupdate.in (&parse_args): Kill old options.
8754 * bin/autoreconf.in (&parse_args): Remove dead options.
8755 Factor some code.
8756 (&autoreconf): Report the directories we enter *and leave*, so
8757 that error messages can be easily located, and use GNU Make
8758 format, so that Emacs' compile mode understands us.
8759 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8760 if some file was changed instead of `print'.
8761 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
8762 (&parse_args): Remove the dead options.
8763 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
8764 autoheader's quiet mode.
8765 (AT_CHECK_AUTOUPDATE): Likewise.
8766 * tests/tools.at (autoupdate): Adjust.
8767 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8769 2002-10-11 Akim Demaille <akim@epita.fr>
8771 No longer use CPP to check for the existing of headers: use CC to
8772 check for compilability.
8774 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
8775 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
8776 (_AC_CHECK_HEADER_NEW): Rename as...
8777 (AC_CHECK_HEADER): this.
8779 * lib/autotest/general.m4 (AT_INIT): Include the failed test
8780 numbers in the Subject suggestion.
8782 2002-10-11 Akim Demaille <akim@epita.fr>
8784 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
8785 Suggest using AC_CHECK_DECLS instead.
8787 2002-10-11 Akim Demaille <akim@epita.fr>
8789 * tests/torture.at (AC_ARG_VAR): Have configure report the value
8790 of `precious'.
8792 2002-10-11 Akim Demaille <akim@epita.fr>
8794 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
8795 file name to enable parallel executions.
8796 From Sam Varshavchik.
8798 2002-10-08 Akim Demaille <akim@epita.fr>
8800 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8801 aclocal invocation, as Gettext macros might not be visible to
8802 aclocal.
8803 Instead of blindly running autopoint, scan configure.ac (not the
8804 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8805 Reported by Paul D. Smith.
8807 2002-10-08 Paul Eggert <eggert@twinsun.com>
8809 Work around problems found when POSIXLY_CORRECT=1 is set.
8810 None of this seems to have anything to do with POSIX, really,
8811 but it's how Perl getopt works.
8812 * bin/autom4te.in (parse_args): Configure GetOpt with
8813 "permute", too.
8814 * doc/autoconf.texi (Invoking autom4te):
8815 --warning -> --warnings.
8816 * lib/autom4te.in: --warning -> --warnings.
8818 2002-09-28 Akim Demaille <akim@epita.fr>
8820 * doc/autoconf.texi (autom4te.cache): New section.
8822 2002-09-28 Akim Demaille <akim@epita.fr>
8824 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
8825 (Automake-preselections): Update.
8826 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
8828 2002-09-28 Akim Demaille <akim@epita.fr>
8830 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
8831 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
8832 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8833 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
8835 2002-09-28 Akim Demaille <akim@epita.fr>
8837 * tests/torture.at (Configuring subdirectories): Be robust to
8838 users who use config.site to require for a cache: in this case,
8839 the two last configure runs, using two different sets of
8840 arguments, trigger a legitimate error.
8842 2002-09-28 Akim Demaille <akim@epita.fr>
8844 * tests/m4sh.at (Functions Support, Functions and return Support):
8845 New.
8847 2002-09-28 Akim Demaille <akim@epita.fr>
8849 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
8850 autoheader are Perl programs.
8851 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
8852 (autom4te): Specify that the sources are in the $srcdir.
8853 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8855 2002-09-28 Akim Demaille <akim@epita.fr>
8857 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
8858 (tm_zone): Move their rules to...
8859 * lib/autoconf/types.m4: here, using AN_ macros.
8860 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8861 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8862 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8863 * lib/autoconf/programs.m4: here.
8864 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
8865 (ETAGS_FOR_AUTOCONF): New.
8866 Use it.
8868 2002-09-28 Akim Demaille <akim@epita.fr>
8870 * lib/autoconf/autoscan.m4: New file.
8871 * lib/autoconf/autoconf.m4: Include it.
8872 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
8873 that were listed in the original autoscan.list.
8874 * lib/autoconf/headers.m4: Similarly with headers.
8875 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8876 (.m4.m4f): Don't pass --prepend-include, since that's done by
8877 tests/autom4te itself.
8878 * lib/autoscan/Makefile.am: Include freeze.mk.
8879 (autoscan.list): New target --this file is no longer a source.
8880 (autoscan.pre): New file.
8882 2002-09-28 Akim Demaille <akim@epita.fr>
8884 * bin/autoscan.in (@kinds): Make them singular.
8885 Adjust all uses.
8886 (&init_tables): When --debug, report the list of rules to ease
8887 tracking changes in autoscan.list.
8888 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8890 2002-09-28 Akim Demaille <akim@epita.fr>
8892 * lib/autoscan/functions, lib/autoscan/headers,
8893 * lib/autoscan/identifiers, lib/autoscan/makevars,
8894 * lib/autoscan/programs: Merge into...
8895 * lib/autoscan/autoscan.list: this.
8896 * bin/autoscan.in (&init_tables): Adjust.
8898 2002-09-28 Akim Demaille <akim@epita.fr>
8900 * lib/autoscan/functions, lib/autoscan/headers,
8901 * lib/autoscan/identifiers, lib/autoscan/makevars,
8902 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8903 `functions' line is now prefixed with `function:'.
8904 * bin/autoscan.in (&init_tables): Adjust.
8906 2002-09-28 Akim Demaille <akim@epita.fr>
8908 From now on, autoscan files must always map a macro name to a
8909 word: there is no `default' macro for autoscan.
8911 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8912 all.
8913 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8914 explicit.
8916 2002-09-28 Akim Demaille <akim@epita.fr>
8918 * bin/autoscan.in (%c_keywords): Remove.
8919 (&used): Keep only track of the words we might be interested in.
8920 (&output_kind): It is no longer needed to look for non active
8921 checks.
8923 2002-09-27 Akim Demaille <akim@epita.fr>
8925 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
8926 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
8927 * lib/autoscan/functions: Adjust.
8928 * doc/autoconf.texi (Particular Functions): Adjust.
8930 2002-09-27 Akim Demaille <akim@epita.fr>
8932 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8933 from /tmp.
8934 Thanks to Bill Moseley and Paul Eggert.
8935 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8936 the tmpdir must be created.
8937 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8938 dir be in the build tree, instead of $TMPDIR.
8940 2002-09-27 Akim Demaille <akim@epita.fr>
8942 * bin/autoscan.in: Improve the comments.
8943 (&parse_args): Drop obsolete undocumented options.
8944 (&output_kind): Output warnings.
8945 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
8946 (getwd): Trigger a warning.
8948 2002-09-26 Akim Demaille <akim@epita.fr>
8950 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8951 Reported by Ralf Corsepius.
8952 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8954 2002-09-26 Akim Demaille <akim@epita.fr>
8956 Single suffix rules and seperated dependencies are not portable.
8958 * doc/autoconf.texi (Installation Directory Variables): Update.
8959 (Limitations of Make): Some about `Single Suffix Rules and
8960 Separated Dependencies'.
8961 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8962 (ifnames, autoscan, autom4te): Un-factor into several rules.
8964 2002-09-25 Paul Eggert <eggert@twinsun.com>
8966 * BUGS (Interoperability bugs): New section. Mention libtool
8967 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8969 2002-09-24 Paul Eggert <eggert@twinsun.com>
8971 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8972 make handles suffix-rules differently from GNU make.
8974 * bin/Makefile.am (SUFFIXES, .in): Remove.
8975 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8976 Move the body of the old .in rule here.
8978 2002-09-16 Akim Demaille <akim@epita.fr>
8980 i960 compilers create `b.out' files by default.
8981 Reported by Ralf Corsepius.
8983 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8984 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8986 2002-09-13 Paul Eggert <eggert@twinsun.com>
8988 * doc/autoconf.texi (Particular Headers): Remove obsolete
8989 reference to `struct timezone' in the description of
8990 AC_HEADER_TIME.
8992 2002-09-13 Akim Demaille <akim@epita.fr>
8994 Version 2.54.
8996 * config/config.sub, config/config.guess: Update.
8997 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8998 * Makefile.am: Adjust.
9000 2002-09-13 Akim Demaille <akim@epita.fr>
9002 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
9003 reading config.log when the compiler is rejected.
9004 Suggested by Guido Draheim.
9006 2002-09-13 Akim Demaille <akim@epita.fr>
9008 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
9009 (chdir_init) might hang when stat'ing mounted directories.
9010 Reported by Vance Shipley.
9012 2002-09-12 Akim Demaille <akim@epita.fr>
9014 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
9015 the lists.
9017 2002-09-12 Akim Demaille <akim@epita.fr>
9019 * doc/autoconf.texi (Defining Symbols): Present two different
9020 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
9021 difference between 1 argument calls, and 2-3 argument calls.
9023 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
9025 * doc/autoconf.texi: Review grammar and punctuation.
9027 2002-09-11 Paul Eggert <eggert@twinsun.com>
9029 * doc/autoconf.texi: Fix minor formatting, spelling, and
9030 grammatical typos.
9031 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
9032 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
9033 is obsolescent.
9035 2002-09-11 Akim Demaille <akim@epita.fr>
9037 * doc/autoconf.texi (Questions): Rename as...
9038 (FAQ): this.
9039 (Defining Directories): New.
9041 2002-09-09 Akim Demaille <akim@epita.fr>
9043 * doc/autoconf.texi (Making testsuite Scripts): Update.
9044 Suggested by Nishio Futoshi.
9046 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
9048 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
9049 plain `@' is wanted.
9051 2002-09-09 Akim Demaille <akim@epita.fr>
9053 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
9054 `duplicates', since the algorithm was too naive and could keep
9055 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
9056 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9057 Reported by Ralf Corsepius.
9058 * tests/torture.at (Configuring subdirectories): Exercise these
9059 cases.
9061 2002-09-09 Akim Demaille <akim@epita.fr>
9063 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
9064 looking for a replacement file.
9065 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9066 directory is relative.
9067 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9068 directory definition.
9069 Reported by Andreas Schwab and Jim Meyering.
9071 2002-09-06 Akim Demaille <akim@epita.fr>
9073 * doc/autoconf.texi (Setting Output Variables): Clarify what
9074 precious variables are.
9075 Suggested by Pontus Skoeld.
9077 2002-09-05 Akim Demaille <akim@epita.fr>
9079 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9080 (ifnames, autoscan, autom4te): Since we don't only depend on
9081 configure.ac variables (such as VERSION etc.), but also on prefix
9082 and so forth, depend on Makefile, not configure.ac.
9083 Reported by Alexandre Duret-Lutz.
9084 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9086 2002-09-05 Kevin Ryde <user42@zip.com.au>
9088 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9089 doesn't seem to be confined to ia64, just say "some versions".
9091 2002-09-04 Akim Demaille <akim@epita.fr>
9093 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9094 Automake 1.6c.
9095 * Makefile.am (maintainer-clean-local): Remove.
9096 (MAINTAINERCLEANFILES): Remove COPYING.
9098 2002-09-03 Paul Eggert <eggert@twinsun.com>
9100 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9101 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9102 Brinkmann.
9104 2002-09-03 Akim Demaille <akim@epita.fr>
9106 * configure.ac: Bump to 2.53d.
9107 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9108 as of today, on Automake's team suggestion.
9110 2002-09-03 Akim Demaille <akim@epita.fr>
9112 Version 2.53c.
9114 2002-09-02 Akim Demaille <akim@epita.fr>
9116 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9117 SITE_MACRO_DIR.
9118 * configure.ac: Disable SITE_MACRO_DIR.
9120 2002-09-02 Jim Meyering <meyering@lucent.com>
9122 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9123 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9124 Also, tweak grammar: s/make sure to/be sure to/.
9126 2002-09-02 Paul Eggert <eggert@twinsun.com>
9128 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9129 directory names are generally preferable to physical names.
9131 2002-09-02 Akim Demaille <akim@epita.fr>
9133 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9134 Reported by Raja R. Harinath.
9135 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9136 * bin/autoupdate.in: Use error instead of die.
9138 2002-09-01 Paul Eggert <eggert@twinsun.com>
9140 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9141 ordinary shell concatenation rather than echo+tr+sed command that
9142 runs afoul of a long-line-related sed bug in Solaris 8.
9144 * bin/autoheader.in (parse_args): --warning -> --warnings.
9146 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9147 stdout, as traditional "ls" does.
9148 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9149 _AC_COMPILER_EXEEXT_O): Likewise.
9150 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9152 * bin/autoconf.as: Add --prepend-include option. This patch was
9153 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9154 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9156 * bin/autoconf.in, configure: Regenerate.
9158 * doc/autoconf.texi (Special Shell Variables): Mention
9159 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9161 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9162 MAILPATH and set PS1, PS2, PS4 to default values, to work
9163 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9164 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9165 the Autoconf documentation specifies; fall back to "unset" only if
9166 this fails. Use a shell for-loop for this rather than an m4 loop,
9167 to shorten the output script.
9169 2002-08-30 Paul Eggert <eggert@twinsun.com>
9171 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9172 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9173 for the CDPATH problem. Document PWD.
9174 (Limitations of Builtins): Document the problem that "cd $foo" and
9175 "ls $foo" may refer to different directories in shells conforming
9176 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9177 example, since the old example is now out of date.
9179 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9180 FOO" and "ls FOO" talk about different directories; this catches
9181 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9182 spaghetti.
9184 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9185 of rolling our own unset.
9186 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9187 in practice we needn't worry about CDPATH if unset doesn't work.
9189 * Makefile.in, aclocal.m4, bin/Makefile.in,
9190 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9191 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9192 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9193 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9194 tests/Makefile.in: Regenerate with Automake 1.6.3.
9196 * config/config.guess, config/config.sub, config/mkinstalldirs:
9197 Update.
9199 * configure: Regenerate with self.
9201 2002-08-30 Kevin Ryde <user42@zip.com.au>
9203 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9204 default output.
9206 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9208 * bin/autom4te.in (Request::load): Correctly test for "do" read
9209 failure.
9211 2002-08-29 Akim Demaille <akim@epita.fr>
9213 * lib/Autom4te/General.pm (&xqx): New.
9214 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9215 hand, which is not portable.
9216 (&error): New.
9217 * bin/autom4te.in: Use them.
9218 Use &error instead of die.
9219 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9220 Adjust.

9224 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9225 default list of compilers to try, since it was long ago superseded
9226 by the ksh fc builtin. Suggested by Steven G. Johnson.
9228 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9230 * doc/autoconf.texi (Invoking autom4te): End the option table,
9231 fixing a bug introduced by the previous patch.

9247 * doc/install.texi: Include copyright symbol in copyright notice.
9249 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9250 Replace with:
9251 (AM_MAKEINFOFLAGS): New macro.
9252 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9253 * Makefile.am (INSTALL): Use the new macros.
9254 Use -o rather than --output, since "missing" does not grok --output.
9256 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9258 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9259 comments do not always work. Never trust the exit status of
9260 `make -k'.
9262 2002-07-24 Kevin Ryde <user42@zip.com.au>
9264 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9265 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.

9272 Bug reported by Stefan `Sec' Zehl.
9274 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

9394 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
9395 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
9396 so that Emacs setups GNU style for perl-mode and cperl-mode.
9398 2002-06-27 Paul Eggert <eggert@twinsun.com>
9400 * config/install-sh: Quote $src. Prefer || to test's -o option,
9401 as per "Limitations of Builtins".
9402 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
9403 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9405 * tests/mktests.sh: Use grep instead of fgrep, as per
9406 "Limitations of Builtins".
9408 2002-06-15 Paul Eggert <eggert@twinsun.com>
9410 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
9411 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
9412 so that we consistently test the just-built programs.
9413 * tests/wrappl.as: Likewise.

9421 * bin/autoreconf.in (autoconf, autoheader): Likewise.
9422 * bin/autoscan.in (autom4te): Likewise.
9423 * bin/autoupdate.in (autom4te): Likewise.
9425 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
9426 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
9427 on Solaris 2.5.1.
9429 2002-06-11 Andreas Schwab <schwab@suse.de>
9431 * doc/autoconf.texi: Add more dir entries.
9433 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9435 * bin/autom4te.in ($cache): Don't define using `$me', the name
9436 of the cache should not depend on the name under which autom4te
9437 was installed.
9439 2002-06-07 Akim Demaille <akim@epita.fr>
9441 * tests/tools.at (autoconf: forbidden tokens, basic)

9445 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
9447 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
9448 _AC_LANG_PROGRAM_C_F77_HOOKS.
9450 2002-06-07 Akim Demaille <akim@epita.fr>

9453 rename as...

9456 AC_FUNC_FNMATCH_GNU.
9458 2002-06-07 Akim Demaille <akim@epita.fr>
9460 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
9461 Rosetta Stone for Unix.
9463 2002-06-07 Akim Demaille <akim@epita.fr>
9465 * bin/autom4te.in (warn_forbidden): When rejecting a token,
9466 suggest m4_pattern_allow.
9467 Suggested by Adam J. Richter.
9469 2002-06-07 Akim Demaille <akim@epita.fr>
9471 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
9472 ac_config_libobj_dir.
9473 (AC_CONFIG_LIBOBJ_DIR): New.
9474 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
9475 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
9476 Use ac_config_libobj_dir to find the replacement files.
9477 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
9478 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)

9481 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.

9485 2002-06-06 Paul Eggert <eggert@twinsun.com>
9487 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
9488 if ln doesn't work.
9489 * NEWS: Likewise.
9490 * doc/autoconf.texi (Configuration Links): Likewise.
9491 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
9493 2002-06-05 Paul Eggert <eggert@twinsun.com>
9495 * config/config.guess, config/config.sub, config/texinfo.tex:
9496 Update from masters.

9521 * NEWS, doc/autoconf.texi (Particular Types): Document it.

9525 2002-05-23 Akim Demaille <akim@epita.fr>
9527 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
9528 version of Autoconf that is discussed.
9530 2002-05-22 Paul Eggert <eggert@twinsun.com>
9532 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
9533 from the default list of compilers to try. Suggested by
9534 Kate Hedstrom.
9535 * NEWS: Document the above.
9536 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
9538 2002-05-17 Paul Eggert <eggert@twinsun.com>
9540 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9541 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9542 This improves on an earlier suggestion by H. Peter Anvin.
9544 2002-05-16 Paul Eggert <eggert@twinsun.com>
9546 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9547 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9548 Both macros now accept an optional source-dir arg.
9549 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9551 * NEWS: Document this.
9552 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9554 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9555 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9556 not for GNU extensions; this undoes part of the 2000-11-03 change,
9557 reverting to 2.13-compatible behavior.
9558 Add new optional argument DIR.
9559 (AC_FUNC_FNMATCH_GNU): New macro.
9561 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9563 2002-05-08 Paul Eggert <eggert@twinsun.com>
9565 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9566 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9567 and it causes a 'test' syntax error if it fails.
9568 Bug reported by Stephen Gildea.
9570 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9571 If prototypes are supported, use them to check this at compile-time,
9572 instead of trying to check it at run-time. If we must do a run-time
9573 check, assume that setvbuf is standard when cross-compiling, as
9574 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9575 Bug reported by Paul D. Smith.
9577 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9578 argument specifying location of getloadavg.c. This removes a
9579 FIXME. This idea was taken from Jim Meyering's implementation in
9580 textutils.
9581 * doc/autoconf.texi (Particular Functions): Document this.
9582 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9583 that's what the code does; this fixes a bug reported by
9584 Paul D. Smith.
9586 2002-05-03 Akim Demaille <akim@epita.fr>
9588 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9589 autopoint instead of gettextize.
9590 ($uses_alocal): Rename as...
9591 ($uses_aclocal): this.
9592 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9593 Suggested by Bruno Haible.
9595 2002-05-03 Akim Demaille <akim@epita.fr>
9597 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9599 2002-04-29 Paul Eggert <eggert@twinsun.com>
9601 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9602 files to be 1 second older; just set them to be the same time.
9603 Also, sleep 1 second after the first aclocal, to work around
9604 problems with sub-second time stamps on the input files.
9606 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9608 * doc/autoconf.texi: Mention "set -e -x" lossage
9609 under node "Limitations of Builtins".
9611 2002-04-29 Akim Demaille <akim@epita.fr>
9613 * doc/install.texi: Better wording for setting variables when
9614 running configure.
9615 From Christian Cornelssen.
9617 2002-04-29 Akim Demaille <akim@epita.fr>
9619 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9620 of lack of $LINENO support, then the test will compare the $LINENO
9621 in testsuite vs. the lineno in the test file. This is wrong, of
9622 course.
9623 Be sure to protect it.
9624 Reported by Patrick Welche.
9626 2002-04-25 Akim Demaille <akim@epita.fr>
9628 * doc/autoconf.texi (Obsolete Macros): Typo.
9629 Reported by Vladimir Volovich.
9631 2002-04-25 Akim Demaille <akim@epita.fr>
9633 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9634 than some of the input files, hence, on the second run of aclocal,
9635 if some of its input are younger, make them older.
9636 Suggested by Paul Eggert.
9638 2002-04-25 Akim Demaille <akim@epita.fr>
9640 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9641 Thanks to Paul Eggert.
9643 2002-04-25 Akim Demaille <akim@epita.fr>
9645 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9646 and ac_subst_vars be sh variables containing the list of
9647 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9648 DEFAULT diversion.
9649 (_AC_INIT_PREPARE): Use them to log them.
9650 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9651 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9652 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9653 _AC_SUBST_FILES and _AC_SUBST_VARS.
9654 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9656 2002-04-24 Akim Demaille <akim@epita.fr>
9658 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9659 autoheader, so that automake does not complain about a missing
9660 config.h.in that was to be created.
9662 2002-04-23 Akim Demaille <akim@epita.fr>
9664 * bin/autoheader.in (parse_args): --warning takes an argument.
9665 Fixes PR/220.
9667 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9669 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

9684 Reported by Gregory Giannoni.
9686 2002-04-22 Akim Demaille <akim@epita.fr>
9688 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
9689 Fixes false failures on Darwin.
9691 2002-04-21 Paul Eggert <eggert@twinsun.com>
9693 * TODO, bin/autoupdate.in, doc/autoconf.texi,

9695 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

9714 Minor spelling and grammar fixes.
9716 * doc/autoconf.texi: Follow the outline suggested in the GNU
9717 Sample Texts sections of the Texinfo 4.2 manual. Most
9718 importantly, this makes sure that the copyright notices appear in
9719 all output formats. You probably need Texinfo 4.2 to generate
9720 the manual now.
9722 Fix some bugs when using "$@" when there might be zero positional
9723 arguments in cases where this matters.
9725 * bin/autoconf.as: Rewrite so that the problem does not come up.

9746 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9748 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9749 from aclocal.m4 too.
9751 2002-04-12 Akim Demaille <akim@epita.fr>

9755 2002-04-10 Akim Demaille <akim@epita.fr>
9757 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9758 workaround for ${1+"$@"}.
9759 * doc/autoconf.texi (Shell Substitutions): Explain it.
9760 From Oliver Kiddle and Peter Stephenson.
9762 Have M4sh perform minimal shell sanitizing.
9764 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9765 part into...
9766 (_AS_PREPARE): this new macro.

9774 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9775 * lib/autotest/general.m4 (AT_INIT): Likewise.
9776 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9777 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9778 AS_SHELL_SANITIZE.
9780 Use this M4sh to generate Autoconf's shell scripts.
9782 * tests/wrapsh.as: New, precursor of wrapsh.in.
9783 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9784 on Autotest and M4sh.
9785 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9786 (wrapsh.in): New target.
9787 * bin/autoconf.as: New, precursor of autoconf.in.
9788 (autoconf.in): New target.
9790 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

9802 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9803 (Portable Shell): Cross reference to Systemology.
9805 2002-04-05 Akim Demaille <akim@epita.fr>
9807 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9808 directories when descending in a SUBDIRS.
9809 Reported by Ezra Peisach.
9811 2002-04-04 Andreas Schwab <schwab@suse.de>
9813 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9814 contains no literal separators.

9818 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9819 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9820 Use dnl, not the KILL diversion.
9821 Extracted from...
9822 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9823 (AC_CONFIG_LINKS): here.
9824 Adjust.
9825 Don't use the KILL diversion, as it kills spurious output, which
9826 results in failures being hidden.
9827 Use m4_defn where appropriate.
9828 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9829 after the second argument.
9830 Use m4_defn.
9831 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9832 syntax, as it is provided by M4sugar.

9875 to avoid versions of HP C which don't allow that.
9877 2002-03-27 Paul Eggert <eggert@twinsun.com>
9879 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

9891 2002-03-25 Paul Eggert <eggert@twinsun.com>
9893 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9894 as POSIX requires, as it doesn't work with Zsh.
9895 * doc/autoconf.texi (Assignments): Document the problem.
9897 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9899 * doc/autoconf.texi (Limitations of Make): Mention more issue
9900 about VPATH, overriding of macros in sub-makes, and handling of
9901 SHELL.
9903 2002-03-21 Paul Eggert <eggert@twinsun.com>
9905 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9906 problem with here-document buffer boundaries.
9908 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9909 when reinvoking the shell, to work around problems with installers
9910 who put strange things like "cd" commands in their environments.
9912 2002-03-19 Akim Demaille <akim@epita.fr>
9914 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9915 From Aaron Ucko.
9917 2002-03-19 Akim Demaille <akim@epita.fr>
9919 * bin/autoscan.in (scan_file): Specify the location in `&used'
9920 invocations.
9921 From Nicolas Joly.

9925 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9926 From Nishio Futoshi.
9928 2002-03-19 Akim Demaille <akim@epita.fr>
9930 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9932 2002-03-18 Paul Eggert <eggert@twinsun.com>
9934 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9935 (Limitations of Usual Tools): Add mkdir section.
9937 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9938 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9939 back on AS_DIRNAME to compute prefixes otherwise; this is
9940 roughly what mkinstalldirs does. That way, we need not have
9941 our own filename disassembler. The old disassembler did not
9942 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9944 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9945 Create at_test_all by a series of assignments,
9946 not by a single assignment of a long string. The latter causes ksh
9947 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9948 presumably because of a buffer overrun.
9950 2002-03-14 Paul Eggert <eggert@twinsun.com>
9952 * lib/autotest/general.m4 (at_times_skip):
9953 Renamed from at_times. Now a boolean.
9954 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9955 says 'times: not found'.
9957 2002-03-14 Akim Demaille <akim@epita.fr>
9959 * bin/autoreconf.in (&study_gettextize): New.
9960 (&autoreconf): Handle newest gettextize.
9961 Rerun aclocal if needed.
9962 Suggested by Andreas Schwab.
9964 2002-03-13 Akim Demaille <akim@epita.fr>

9973 2002-03-13 Akim Demaille <akim@epita.fr>
9975 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9976 -p'.
9977 From Bob Proulx.
9979 2002-03-12 Akim Demaille <akim@epita.fr>
9981 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9982 m4_require.
9984 2002-03-11 Andreas Schwab <schwab@suse.de>
9986 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9987 does not do it if --with-lispdir is given.
9989 2002-03-08 Akim Demaille <akim@epita.fr>
9991 Version 2.53.
9993 2002-03-08 Akim Demaille <akim@epita.fr>
9995 * doc/autoconf.texi (Subdirectories): Clarify that the
9996 subdirectory should exist.
9998 2002-03-08 Akim Demaille <akim@epita.fr>
10000 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
10002 2002-03-08 Akim Demaille <akim@epita.fr>
10004 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
10005 aliases the actual variables, and modifications of the former
10006 affect the latter.
10008 2002-03-08 Akim Demaille <akim@epita.fr>
10010 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
10011 because of C-c: have m4 output in tmp files, then mv them.
10013 2002-03-08 Akim Demaille <akim@epita.fr>
10015 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
10016 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,

10023 2002-03-05 Akim Demaille <akim@epita.fr>
10025 * doc/autoconf.texi (Specifying Names): Clarification suggested by
10026 Kevin Ryde.
10028 2002-03-05 Akim Demaille <akim@epita.fr>
10030 Version 2.52i.
10032 2002-03-04 Akim Demaille <akim@epita.fr>
10034 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
10035 * lib/autoconf/general.m4 (AC_INIT): More informative error
10036 message for LIBOBJ.
10038 2002-03-04 Akim Demaille <akim@epita.fr>
10040 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
10041 parallel builds.
10043 2002-03-04 Akim Demaille <akim@epita.fr>
10045 * doc/autoconf.texi (Transforming Names): Equality between target
10046 and host is irrelevant.
10047 (Specifying Names, Canonicalizing): Remove all references to the
10048 backward compatibility hooks. Rather, collect them all into...
10049 (Hosts and Cross-Compilation): this new section.
10050 * doc/install.texi (System Type): Ditto.
10051 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state

10056 * doc/autoconf.texi (Evaluation Macros): New.
10057 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10058 useless.
10059 (_m4_foreach): Define the variant with immediate evaluation so
10060 that it contains exactly the items, not an expression which
10061 evaluation is the current item.
10062 (m4_re_string, m4_re_word): Don't over quote them.
10064 2002-03-04 Akim Demaille <akim@epita.fr>
10066 Instead of having stacking `shift's evaluated at the end, let
10067 `foreach' loops immediately evaluate them.
10069 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10070 $*. This is the n-th time I change my mind, but hopefully this is
10071 the last...
10072 (m4_lquote): New.
10073 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10074 efficient.
10075 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10076 it was only a hack for m4_text_wrap.
10077 (m4_car2): Remove, replaced by...
10078 (m4_cdr): New.
10079 (_m4_foreach): Adjust.
10080 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use

10125 Fix Autoconf PR/209.
10126 Also reported by Frank Denis.

10130 2002-02-07 Akim Demaille <akim@epita.fr>
10132 Fix Autoconf PR/207:
10133 AC_PREFIX_PROGRAM fails with dashed program names
10135 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
10136 variable when looking for the prefix program.

10197 optional are the sum of the previous files on the command line'.
10198 Also, pass `--reload-state=' on them, so...
10199 (handle_m4): don't.
10200 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10201 (M4sh): Rely on M4sugar.
10202 (Autotest, M4sh, M4sugar): Use frozen files.
10204 2002-01-31 Akim Demaille <akim@epita.fr>
10206 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
10207 * doc/autoconf.texi (Initializing configure): Adjust.
10209 2002-01-30 Akim Demaille <akim@epita.fr>
10211 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
10212 alphanumeric to `-' instead of `_'.
10214 2002-01-30 Akim Demaille <akim@epita.fr>
10216 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10217 for plain code, the other for cross-compilation code. The latter
10218 is now run with GCC only.
10219 * doc/autoconf.texi (Compilers and Preprocessors): New.
10221 2002-01-30 Akim Demaille <akim@epita.fr>
10223 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
10224 values.
10225 * doc/autoconf.texi (Initializing configure): Explain how to
10226 change AC_INIT default values.
10228 2002-01-29 Akim Demaille <akim@epita.fr>
10230 * tests/torture.at (Configuring subdirectories): Use configure.in,
10231 so that aclocal 1.4 works.
10232 Reported by Alexandre Duret-Lutz and Larry Schmitt.
10234 2002-01-28 Akim Demaille <akim@epita.fr>
10236 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10237 needs an argument.
10239 2002-01-28 Akim Demaille <akim@epita.fr>
10241 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10242 AUTOTEST_PATH *after* it was set.
10243 Don't put `.' in the PATH: the user should be precise and `./' if
10244 needed. In addition, given that the test suite does some `cd', if
10245 `.' is in the path, the `tested programs' sections will report
10246 programs found in the test suite's directory, while during the
10247 tests (performed in their own directory), these programs are no
10248 longer visible. In other words, the results is confusing and
10249 useless.
10250 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10252 2002-01-24 Akim Demaille <akim@epita.fr>
10254 Version 2.52g.
10256 2002-01-24 Akim Demaille <akim@epita.fr>
10258 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
10259 * doc/autoconf.texi: Finally add Akim as an author.
10261 2002-01-24 Akim Demaille <akim@epita.fr>
10263 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
10264 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
10265 Bourne. Use /bin/sh.
10266 From Andreas Buening.
10268 2002-01-24 Akim Demaille <akim@epita.fr>
10270 * config/config.guess, config/config.sub, config/texinfo.tex:
10271 Update from masters.
10273 2002-01-24 Akim Demaille <akim@epita.fr>

10278 * config/missing.m4, config/sanity.m4, config/select.m4,
10279 * config/strip.m4: Remove, to ease sync'ing with any version of
10280 Automake.
10282 2002-01-24 Akim Demaille <akim@epita.fr>
10284 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
10285 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
10286 Reported by Geir Ove Myhr.
10288 2002-01-21 Akim Demaille <akim@epita.fr>
10290 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
10292 2002-01-21 Akim Demaille <akim@epita.fr>
10294 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10295 message on invalid options.
10296 * bin/autom4te.in (parse_args): Don't use
10297 Autoconf::General::getopt with non valid options.
10299 2002-01-17 Jim Meyering <meyering@lucent.com>
10301 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10302 $ac_cv_exeext so we don't use an old, invalid, cached value.
10304 2002-01-11 Akim Demaille <akim@epita.fr>
10306 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
10307 Meyering.

10309 limitation.

10313 2002-01-06 Akim Demaille <akim@epita.fr>
10315 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10316 package.m4, since is really depends upon configure.ac, not
10317 configure.
10318 * doc/autoconf.texi (testsuite Scripts): Adjust.
10319 * tests/Makefile.am (package.m4): New.
10320 EXTRA_DIST it since its a source.
10322 2002-01-06 Akim Demaille <akim@epita.fr>
10324 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10325 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10326 and PACKAGE_BUGREPORT from here...
10327 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10328 arguments.
10329 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10330 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10331 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
10332 * tests/tools.at (autoheader): Adjust.
10333 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
10335 2002-01-06 Akim Demaille <akim@epita.fr>

10339 2002-01-03 Akim Demaille <akim@epita.fr>
10341 * doc/autoconf.texi (Output): Improved wording regarding use of
10342 AC_OUTPUT.
10343 From Olly Betts.
10345 2001-12-18 Kevin Ryde <user42@zip.com.au>
10347 * doc/autoconf.texi (Function Portability): Add notes on sscanf
10348 sometimes needing writable input.
10350 2001-12-17 Jim Meyering <meyering@lucent.com>
10352 * doc/autoconf.texi (New Macros): Tweak wording.
10354 2001-12-14 Akim Demaille <akim@epita.fr>
10356 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10357 trailing files, don't apply `-rf' to files which might not be
10358 created by configure (core, core.*, and *.core), but just `rm -f'.
10359 Suggested by Jonathan Kamens.
10361 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10363 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
10365 2001-12-14 Akim Demaille <akim@epita.fr>
10367 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
10369 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
10371 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
10372 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
10373 abs_srcdir, top_srcpath to abs_top_srcdir.
10374 (_AC_OUTPUT_FILES): Adjust.
10375 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
10376 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
10377 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10379 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
10381 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
10382 C/Fortran linking on HP/UX, by extracting the Fortran library
10383 search path from the LPATH line in the $F77 -v output.
10385 2001-12-12 Kevin Ryde <user42@zip.com.au>
10387 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10388 forbidden file descriptors table.
10390 2001-11-26 Akim Demaille <akim@epita.fr>
10392 * bin/autoscan.in (%c_keywords): Build it at top level.
10393 Map to 1 in order to simplify its uses.
10395 2001-11-26 Akim Demaille <akim@epita.fr>
10397 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10398 Remove $filepath, useless.
10399 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10400 variables, they are really part of the tokens.
10401 Split the input line on spaces and then look for tokens.
10402 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10403 because of `lex$U.$(OBJEXT)'.
10404 (&scan_files): Use "@list" instead of join.
10405 * doc/Makefile.am (CLEANFILES): Add *.fns.
10407 2001-11-26 Akim Demaille <akim@epita.fr>
10409 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10410 Remove, replaced by...
10411 * tests/wrappl.in: Be common for all the Perl executables.
10412 In particular autoscan and autoheader want -I.
10413 * configure.ac: Adjust.
10414 * lib/autoscan/headers: errno.h is portable.
10416 2001-11-26 Akim Demaille <akim@epita.fr>
10418 * bin/autoscan.in (used): New.
10419 Use it.
10421 2001-11-26 Akim Demaille <akim@epita.fr>
10423 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10424 directives.
10425 (&scan_sh_file): Remove a duplicate pattern.
10426 (&check_configure_ac): Use long options.
10427 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10429 2001-11-26 Akim Demaille <akim@epita.fr>
10431 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10432 Before, having a line containing the opening of a multi line
10433 comment made the whole line be ignored.
10435 2001-11-26 Akim Demaille <akim@epita.fr>
10437 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10438 (testsuite Scripts): Be one of its subsection.
10439 (Autotest Logs): New.
10441 2001-11-26 Akim Demaille <akim@epita.fr>
10443 Test groups are now run two directories deeper.
10445 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10446 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10447 at_top_builddir.
10448 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10449 top_srcdir, builddir and top_builddir.
10450 Use `at_*dir' relatively to the directory containing the
10451 suite, use `*dir' when relatively to the current group dir.
10453 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10455 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10456 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10457 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10458 spelling errors.
10460 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10462 * doc/autoconf.texi (Using System Type): Add an example of `case
10463 $host' usage so people quit using `case $target' everywhere.
10465 2001-11-22 Akim Demaille <akim@epita.fr>
10467 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10468 spotted by Jim Meyering.
10470 2001-11-16 Paul Eggert <eggert@twinsun.com>
10472 This patch implements a `long double' suggestion by Oliver Kiddle.
10474 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10475 static, to catch errors if the value isn't known at compile-time
10476 and the compiler supports dynamic arrays. Change its name from
10477 `_array_' to `test_array' to avoid potential name clashes.
10478 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10479 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10480 better than double. Catch a bug in GCC 2.95.2 x86.
10481 * doc/autoconf.texi (C Compiler): Document the above.
10482 * NEWS: Likewise.
10484 2001-11-13 Akim Demaille <akim@epita.fr>
10486 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10487 hand.
10488 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10490 2001-11-13 Akim Demaille <akim@epita.fr>
10492 * lib/autotest/general.m4 (AT_INIT): After having run the test
10493 group, go back to the initial directory, not to at_suite_dir.
10495 2001-11-13 Akim Demaille <akim@epita.fr>
10497 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10498 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10499 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10500 option.
10501 (AT_CHECK_CONFIGURE): Use absolute paths.
10502 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10503 The problem is still the old one: there is no means in M4 (that I
10504 know about) to create a defining macro, because there is no means
10505 to create `$1' etc., therefore, the defining macro ``swallows''
10506 all the arguments meant to the defined macro.
10508 2001-11-13 Akim Demaille <akim@epita.fr>
10510 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10511 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10512 configure.ac.
10513 * tests/aclocal.m4: Remove, as it is no longer used.
10515 2001-11-13 Akim Demaille <akim@epita.fr>
10517 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10518 variable names when referring to a single test group, or to
10519 `suite' when referring to the whole test suite.
10520 `at_last_test' is removed: m4 compute at_format itself.
10521 (at_stdout, at_stder1, at_stderr): New variables.
10522 (AT_CHECK): Use them.
10524 2001-11-13 Akim Demaille <akim@epita.fr>
10526 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10527 in PATH.
10528 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10529 Do it as soon as a test fails, don't wait till the end of the test
10530 suite.
10531 Don't remove $as_me.[0-9]*, since these files no longer exist.
10533 2001-11-13 Akim Demaille <akim@epita.fr>
10535 * tests/tools.at: Use absolute paths, since we are no longer run
10536 in place.
10538 2001-11-13 Akim Demaille <akim@epita.fr>
10540 Now that tests are running in their own private dir, there is no
10541 need to list the files to remove at the end of tests groups.
10543 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10544 (AT_data_files, at_data_files): Remove.
10545 (AT_CLEANUP, AT_DATA): Simplify.
10546 (AT_INIT): Adjust.
10547 Remove the group dir if !debug && !failed.
10548 * tests/atspecific.m4: Adjust.
10550 2001-11-13 Akim Demaille <akim@epita.fr>
10552 Start a new layout for Autotest: `testsuite' creates
10553 `testsuite.dir' in which the at-check-line etc. files are to be
10554 found, and `testsuite.dir/003' where the test group 3 is run.
10556 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10557 at_check_line_file, at_format, at_test_normalized, at_group_dir
10558 are new variables.
10559 Create the directories.
10560 Use absolute paths for at- files.
10561 (AT_CHECK): Adjust.
10563 2001-11-11 Michael Matz <matz@kde.org>
10565 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10566 (m4_car2): New.
10567 (m4_car): Properly quote arguments.
10569 2001-11-13 Akim Demaille <akim@epita.fr>
10571 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10572 with stricter rules on LIBOBJS.
10574 2001-11-12 Paul Eggert <eggert@twinsun.com>
10576 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10577 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10578 __PROTOTYPES too.
10580 2001-11-12 Akim Demaille <akim@epita.fr>
10582 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10584 2001-11-12 Akim Demaille <akim@epita.fr>
10586 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10587 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10588 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10589 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10590 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10591 specify to what the macro should be defined (typically to 1).
10593 2001-11-12 Akim Demaille <akim@epita.fr>
10595 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10596 From Jim Meyering.
10598 2001-11-12 Akim Demaille <akim@epita.fr>
10600 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10601 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10602 definition used by Automake where LEX is +/- "${missing} lex" and
10603 `missing' itself contains variables.
10605 2001-11-12 Akim Demaille <akim@epita.fr>
10607 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10608 Now that M4sh pushes BODY, the comments were output at the end of
10609 the test suites.
10611 2001-11-08 Akim Demaille <akim@epita.fr>
10613 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10614 that we can trace macros from aclocal.m4.
10615 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10616 obsoleted, and redirect to the former anyway.
10617 Reported by Ralf Corsepius.
10619 2001-11-08 Akim Demaille <akim@epita.fr>
10621 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10622 processed only if present.
10623 * tests/torture.at (Configuring subdirectories): Use autoreconf
10624 instead of successive calls to autoconf.
10625 Add a nonexistent subdirectory to exercise the patch above.
10626 Reported by Ralf Corsepius.
10628 2001-11-08 Kevin Ryde <user42@zip.com.au>
10630 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10631 doesn't accept .S files.
10633 2001-11-07 Akim Demaille <akim@epita.fr>
10635 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10636 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10637 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10638 * bin/autom4te.in (warn_forbidden): New.
10639 (handle_output): Use it.
10640 Read m4_pattern_forbid with messages.
10642 2001-11-05 Akim Demaille <akim@epita.fr>
10644 * bin/autom4te.in (--normalize): Remove.
10645 * lib/autom4te.in: Adjust.
10647 2001-11-05 Akim Demaille <akim@epita.fr>
10649 * tests/Makefile.am (testsuite): Rename this target as...
10650 ($(TESTSUITE)): this.
10651 From Nicolas Joly.
10653 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10655 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10656 the --prefix option, also remove it's argument.
10658 2001-11-05 Akim Demaille <akim@epita.fr>
10660 * doc/autoconf.texi (testsuite Invocation): Update.
10661 (Writing testsuite.at): Update.
10663 2001-11-03 Akim Demaille <akim@epita.fr>
10665 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10667 2001-11-03 Akim Demaille <akim@epita.fr>
10669 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10670 (&file_name_is_absolute): New, wrappers around routines from
10671 File::Spec.
10672 Use and export them.
10673 (&find_configure_ac): Optionally take a directory where to look at.
10674 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10675 the arguments.
10676 Default @ARGV to `.', not find_configure_ac.
10677 (&autoreconf): Argument is a directory.
10678 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.

10684 (@export_forward_subs): New.
10685 Add basename, dirname, and fileparse.
10686 (@EXPORT): Adjust.
10687 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10688 Don't look for aclocal flags if we already know aclocal is not
10689 used.
10690 Move aclocal.m4t only if it exists.
10691 Reported by Ezra Peisach.
10693 2001-11-03 Akim Demaille <akim@epita.fr>
10695 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10696 passed on command line, defaulting to ./configure.ac if present.
10697 (&maybe_autoreconf, File::Find): Remove, unused.
10698 (&autoreconf): If autoconf is not used, don't try to trace.
10700 2001-11-02 Akim Demaille <akim@epita.fr>
10702 * configure.ac: Bump to 2.52g.
10704 2001-11-02 Akim Demaille <akim@epita.fr>
10706 Version 2.52f.
10708 2001-11-02 Akim Demaille <akim@epita.fr>
10710 * config/config.guess, config/config.sub, doc/standards.texi:
10711 * config/lispdir.m4: Update from masters.
10712 * configure.ac: Bump to 2.52f.
10714 2001-11-02 Akim Demaille <akim@epita.fr>
10716 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10717 Don't run aclocal when aclocal.m4 is not from aclocal.
10718 From Ezra Peisach.
10719 Don't run libtoolize and gettextize if --install is not given.
10721 2001-11-01 Paul Eggert <eggert@twinsun.com>
10723 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10724 be invoked before _AS_LINENO_PREPARE.
10725 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10726 than character ranges.
10728 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10729 invoking AS_BASENAME. Set the locale variables to 'C' if
10730 possible, as POSIX requires this to get the traditional
10731 behavior.
10732 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10734 2001-10-31 Paul Eggert <eggert@twinsun.com>
10736 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10737 with {}, as that triggers a bug in Bash 2.05.
10739 (_AS_LINENO_PREPARE): Use Sed rather than
10740 Awk. Fix the sed prepass to work even if there are multiple
10741 instances of $LINENO on the same line. Do not substitute for
10742 other variables like $LINENOT. Do not check file dates; such a
10743 check is unreliable on sufficiently fast machines, and removing
10744 the check makes the code simpler and more reliable. Check for
10745 output and chmod failures.
10747 * doc/autoconf.texi (Special Shell Variables): Document
10748 the above.
10750 2001-10-31 Akim Demaille <akim@epita.fr>
10752 * tests/Makefile.am (atconfig): Remove this target, Automake
10753 handles it now.
10755 2001-10-31 Akim Demaille <akim@epita.fr>
10757 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10758 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10759 provided, while it is optional.
10760 * configure.ac: Adjust.
10762 2001-10-26 Paul Eggert <eggert@twinsun.com>
10764 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10765 lib/Autom4te/Struct.pm:
10766 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10767 with 5.005_02.
10769 * doc/autoconf.texi (Special Shell Variables): Document some
10770 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10772 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10773 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10774 eval $LINENO is not portable in practice.
10776 2001-10-24 Akim Demaille <akim@epita.fr>
10778 * lib/Autom4te/General.pm (backname): New.
10780 2001-10-24 Akim Demaille <akim@epita.fr>
10782 * m4/: Remove, merged into...
10783 * config/: here.
10785 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10787 * doc/autoconf.texi (Shellology): Mention the problems with bash
10788 2.05's use of ANSI quoting in its `set' builtin.
10790 2001-10-22 Paul Eggert <eggert@twinsun.com>
10792 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10793 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10794 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10795 POSIX decided to standardize on the int flavor of strerror_r.
10796 Always do char* test, as there's no reason not to.
10797 Assign to a char* var, to catch strerror_r that returns int*.
10799 * doc/autoconf.texi (Particular Functions):
10800 Document the above changes. Also, document the fact that
10801 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10803 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10805 2001-10-20 Akim Demaille <akim@epita.fr>
10807 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10808 the executable was missing from the log.

10812 * lib/Autom4te/General.pm (&update_file): If destination is
10813 unchanged, remove the source.
10814 (&up_to_date_p): Don't be verbose, be debug.
10815 * bin/autoreconf.in: No longer support --m4dir.
10816 (&autoreconf): Display the full path of the configure.ac we are
10817 studying.
10818 Trace it only once.
10819 Be sure to honor --force with gettextize.
10820 Always run aclocal.
10821 * doc/autoconf.texi: Adjust.
10823 2001-10-20 Akim Demaille <akim@epita.fr>
10825 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10826 Remove, dead.
10827 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10828 `intl' is already present, as it refuses unless --force.
10829 (&parse_args): Use -I, --include instead of the old Autoconf
10830 options.
10831 ($localdir, $autoconf_dir): Remove.
10832 (@include): New.
10833 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10835 2001-10-19 Jens Petersen <petersen@redhat.com>

10843 file in @configure_input@.
10844 Don't mention `automatically' in addition to `generated'.
10845 * tests/torture.at (#define header templates): Adjust.
10847 2001-10-19 Akim Demaille <akim@epita.fr>
10849 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10850 comment, explain how to install automatic mode selection.
10851 From Russ Allbery.
10853 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10855 * bin/autoreconf.in (autoreconf): Display the path to the
10856 configure.ac being studied.
10858 2001-10-18 Paul Eggert <eggert@twinsun.com>
10860 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10861 long, to work around a bug in the HP C compiler version HP92453-01
10862 B.11.11.23709.GP.
10864 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10865 (AS_BASENAME_EXPR): New macro.
10866 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10867 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10868 and fall back on 'sed' only if the other two fail. This makes
10869 AS_BASENAME act more like AS_DIRNAME.
10870 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10871 contains white space.
10872 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10873 Use AS_DIRNAME, since I think it's now DOS-friendly.
10874 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10875 Allow "dirname //FOO" to return either / or //, as POSIX allows
10876 either behavior.
10878 2001-10-10 Akim Demaille <akim@epita.fr>
10880 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
10881 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
10882 From Eric Sharkey.
10884 2001-10-10 Akim Demaille <akim@epita.fr>
10886 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
10887 m4_define, since...

10926 bother with $force since...
10927 * lib/Autom4te/General.pm: does.
10929 2001-10-08 Akim Demaille <akim@epita.fr>
10931 * bin/autoreconf.in: Rewrite in Perl.
10932 * configure.ac: Adjust.

10981 2001-10-08 Akim Demaille <akim@epita.fr>
10983 Use `add-log-current-defun-function' for ChangeLog creation.
10984 Suggested by Tom Tromey.

11004 * tests/base.at: Adjust the tests to use AS_INIT.
11005 * tests/tools.at (AT_DATA_FORBIDDEN): New.

11016 empty, and if we can find a shell that does support LINENO,
11017 then set CONFIG_SHELL to that shell and then re-execute
11018 ourselves with CONFIG_SHELL.
11020 2001-10-05 Paul Eggert <eggert@twinsun.com>
11022 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
11023 doesn't exist. Remove *.tmp, as a .tmp file is created during the
11024 build of $(TESTSUITE).
11026 2001-10-05 Akim Demaille <akim@epita.fr>
11028 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

11070 instead of exec'ing to preserve $0 and $@.
11072 2001-10-01 Akim Demaille <akim@epita.fr>
11074 * tests/testsuite (AT_INIT) <at_pass_list>: New.

11093 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
11094 Don't use nested parenthesization. This patch was originally
11095 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
11096 but somehow it didn't get incorporated then.
11097 * doc/autoconf.texi (Limitations of Usual Tools):
11098 Clarify remark about sed and nested parenthesization.
11100 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
11101 Report an error if the size cannot be determined even though
11102 the type exists.
11103 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11104 Check for `expr' arithmetic overflow, and for compilation failure,
11105 and invoke a new argument $4 if either is discovered.
11106 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
11107 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
11109 2001-09-28 Akim Demaille <akim@epita.fr>

11123 2001-09-27 Akim Demaille <akim@epita.fr>
11125 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
11126 generates too many bug reports.

11129 status when executing the ACTION-IF-FALSE.

11149 Raja R Harinath:

11250 2001-09-22 Akim Demaille <akim@epita.fr>
11252 Rely on `$LINENO' when possible instead of `__oline__'.
11254 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
11255 `$LINENO' support replacement when not supported.
11256 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
11257 them explicitly to be sure they are not output before this section
11258 (via m4_require). Cosmetic only.

11267 character (u: -> ue) in a code comment.
11268 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
11269 it works.
11271 2001-09-21 Akim Demaille <akim@epita.fr>

11274 Suggested by Jim Meyering.
11276 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11278 * lib/autoconf/programs.m4: Use extensions listed in
11279 $ac_executable_extensions when looking for programs.

11291 PATH_SEPARATOR.
11292 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

11298 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

11301 arguments. Fixed a typo.
11303 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11305 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

11308 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11310 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
11311 * bin/autoupdate.in: Ditto.
11312 * bin/autoheader.in: Reworded a few comments.
11313 * bin/autoconf.in: Reworded help text for a few options.

11317 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11319 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
11320 already have $file). Set output files to binary mode (helps avoid
11321 CR issues on DOSish systems).
11323 2001-09-19 Akim Demaille <akim@epita.fr>
11325 * lib/autotest/general.m4: Englishoes.
11326 From Tim Van Holder and Alexey Mahotkin.
11328 2001-09-18 Paul Eggert <eggert@twinsun.com>
11330 * doc/autoconf.texi (Common Shell Constructs): New node,
11331 documenting AS_DIRNAME.
11332 (Limitations of Usual Tools): Refer to it when discussing dirname.
11333 Also, update discussion of POSIX standard to reflect latest draft.
11335 * lib/autoconf/c.m4:
11336 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11338 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11339 Do not pass a first argument with leading '-'
11340 to expr, by parenthesizing initial integers that might be negative.
11342 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11343 now merely checks whether it is an error to pass an argument
11344 to getpgrp.
11346 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11347 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11348 whether it is a (compile-time) error to pass an argument to
11349 getpgrp. This simpler test supports the revised documentation,
11350 and is all that AC_FUNC_GETPGRP's users really need.
11352 2001-09-18 Akim Demaille <akim@epita.fr>
11354 * doc/autoconf.texi (Limitations of Make) <$<>: New.
11356 2001-09-18 Akim Demaille <akim@epita.fr>

11364 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11365 correctly.
11366 Add test for AS_BASENAME.
11367 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11368 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11369 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11370 * tests/base.at: Fixed the expected responses. The old ones were
11371 one line out...
11372 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11373 the documentation claims it should (and how it behaved in 2.13).
11375 2001-09-18 Akim Demaille <akim@epita.fr>
11377 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11378 the AC_CONFIG_COMMANDS invocation.
11379 This also solves the name clash problems.
11380 Don't set the package's ID.
11381 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11382 No longer to be shipped.
11383 (version.in): Remove.
11384 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11385 * lib/autoconf/status.m4: Adjust.
11386 Use `m4_PACKAGE_STRING'.
11387 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11388 the only optional argument is the name of the test suite.
11389 Expect `package.m4' to define the package signature.
11390 * lib/autom4te.in (Autotest): Add `package.m4?'.
11391 * tests/Makefile.am (package.m4): New.
11392 * tests/suite.at: ifnames is a victim.
11394 2001-09-18 Akim Demaille <akim@epita.fr>
11396 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11397 AC_LIBSOURCE, AC_CONFIG_FILES.
11398 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11399 program version string doesn't match the package's.
11400 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11401 after `(cached)'.

11405 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11406 Allow expression to return any value that can fit into unsigned long
11407 (not int, as before). Check for output errors.
11409 2001-09-17 Bruno Haible <haible@ilog.fr>
11411 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11412 Always include <stdio.h> and <stdlib.h>. Evaluate
11413 the expression in an extra function before these includes. Call
11414 fprintf "%d" only after ensuring the argument is of type 'int'.
11415 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11417 2001-09-17 Paul Eggert <eggert@twinsun.com>
11419 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11420 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11421 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11422 when they don't exist.
11424 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11425 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11426 need it.
11428 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11429 version with the version used by fileutils 4.1, except use
11430 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11431 we don't need it.
11433 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11435 2001-09-13 Akim Demaille <akim@epita.fr>
11437 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11438 _first_.
11439 Reported by Gerrit P. Haase.

11443 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

11458 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
11459 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
11460 Likewise.

11463 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
11464 AT_tests_all for consistency.

11471 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
11473 2001-09-13 Akim Demaille <akim@epita.fr>
11475 * lib/autotest/general.m4 (AT_INIT): Create and remove
11476 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11477 test suites can cohabit.
11479 2001-09-13 Akim Demaille <akim@epita.fr>
11481 * tests/mktests.sh: Don't output banners for empty test files.
11483 2001-09-13 Akim Demaille <akim@epita.fr>

11531 2001-09-10 Akim Demaille <akim@epita.fr>
11533 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

11549 2001-09-07 Akim Demaille <akim@epita.fr>

11552 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
11553 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
11554 related variables into `at_package_*'.

11568 (AT_INIT): Let atconfig and atlocal be both optional.
11569 Adjust PATH computation.

11572 2001-09-07 Akim Demaille <akim@epita.fr>
11574 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon
11575 m4sugar/version.m4.
11577 2001-09-05 Akim Demaille <akim@epita.fr>
11579 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'

11581 From Uwe Seimet.
11583 2001-09-05 Akim Demaille <akim@epita.fr>
11585 * bin/autom4te.in: --language is -l, not -s.
11587 2001-09-05 Akim Demaille <akim@epita.fr>
11589 Be ready to handle filenames as stupid as `dnl.at', for if even
11590 the maintainer is dumb enough to do that...
11592 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11593 excellence in M4 quotation: consider `__file__' is active.
11595 And BTW, when invoking m4, pass the --include in the right order:
11596 the wrong one.
11598 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
11599 4m.
11601 2001-09-05 Akim Demaille <akim@epita.fr>
11603 * lib/Autom4te/XFile.pm: New lib file.
11604 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
11605 * bin/autoheader.in: Use it.
11607 2001-09-05 Akim Demaille <akim@epita.fr>
11609 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
11610 defined.
11612 2001-09-05 Akim Demaille <akim@epita.fr>

11617 * bin/autoscan.in: Use `getopt' and `find_files' etc.
11618 Add -I, --include support.
11619 * doc/autoconf.texi (autoscan Invocation): Adjust.
11621 2001-09-05 Akim Demaille <akim@epita.fr>
11623 CVS GNU M4 doesn't like `undefine(undefined)'.
11625 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
11626 New, extracted from main.
11627 Use IO::File wherever possible.
11628 (input.m4): Be constant, use -I instead of hard coding $tmp.
11629 Therefore be a quoted heredoc.
11630 Don't invoke `_au_disable', since ac was not loaded, but just
11631 `unm4.m4'.
11633 2001-08-31 Akim Demaille <akim@epita.fr>
11635 Version 2.52d.
11637 2001-08-31 Akim Demaille <akim@epita.fr>
11639 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
11640 previous patch.
11641 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
11643 2001-08-31 Akim Demaille <akim@epita.fr>
11645 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
11646 serious problems handling heredocs in heredocs.
11647 Reported by Nicolas Joly.
11649 2001-08-31 Akim Demaille <akim@epita.fr>
11651 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
11652 (Making testsuite Scripts): Update.
11654 2001-08-31 Akim Demaille <akim@epita.fr>
11656 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11658 2001-08-31 Akim Demaille <akim@epita.fr>
11660 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11661 (testsuite Scripts): There is no such thing as `atconfig.in'.
11662 And actually one diagram is missing: test suite runtime.
11664 2001-08-31 Akim Demaille <akim@epita.fr>
11666 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11667 inverse order.
11669 2001-08-31 Akim Demaille <akim@epita.fr>
11671 * bin/autoupdate.in (@include): `installcheck' revealed the path
11672 to m4sugar was lacking!
11674 2001-08-31 Akim Demaille <akim@epita.fr>
11676 * man/Makefile.am (.x.1): We really have to pass
11677 autom4te_perllibdir.
11679 2001-08-31 Akim Demaille <akim@epita.fr>
11681 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11682 debug scripts, in particular passing explicitly listed tests to
11683 run is stupid.
11685 2001-08-31 Akim Demaille <akim@epita.fr>
11687 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11688 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11689 Use directly autom4te, not autoconf.
11690 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
11692 2001-08-31 Akim Demaille <akim@epita.fr>
11694 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
11695 * bin/autoheader.in (%symbol): Strip arguments of macros.

11701 2001-08-31 Akim Demaille <akim@epita.fr>
11703 * bin/autom4te.in (&parse_args): Die on unknown languages.
11704 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
11705 need for autoconf.
11706 Promote --include over --macrodir and other obsolete options.
11708 2001-08-31 Akim Demaille <akim@epita.fr>
11710 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
11711 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
11712 * bin/autom4te.in ($autoconf): Pass --force.
11713 `print $out' doesn't print `$_' but `$out'.
11714 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11715 (autoheader): Pass --force since the test suite goes too fast for
11716 the time stamps.
11717 Adjust to the new autoheader messages.
11719 2001-08-31 Akim Demaille <akim@epita.fr>
11721 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11722 Check the completeness of the #template.
11723 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
11724 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
11725 invocation.
11727 2001-08-31 Akim Demaille <akim@epita.fr>
11729 * lib/Autom4te/General.pm (&find_file, &update_file): New.
11730 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11731 Drop AC_MACRODIR dead for real.
11732 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11733 `autoheader: `config.hin' is created'.
11734 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11736 2001-08-31 Akim Demaille <akim@epita.fr>
11738 * bin/autoheader.in: Rewrite in Perl.
11739 * tests/autoheader: Adjust.
11741 2001-08-31 Akim Demaille <akim@epita.fr>
11743 * bin/autoconf.in (--include, -I): New option.
11744 Map --localdir, --autoconf-dir onto it.
11745 Forward autom4te's options instead of interpreting them.
11746 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11747 There is no such envvar since the inception of autom4te.cfg.
11748 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11749 * bin/autoupdate.in: Adjust, and perform more control.
11750 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11751 * tests/autoconf: Dittowise.
11753 2001-08-31 Akim Demaille <akim@epita.fr>
11755 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11756 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11757 optionally `FILE'.
11758 Use -e, not -f, since /dev/null for instance is OK.
11759 (&parse_args): Adjust.
11760 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11762 2001-08-31 Akim Demaille <akim@epita.fr>
11764 * configure.ac: Also find tested executables in bin.
11765 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11766 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11767 installed peer executables, only PATH is allowed to resolve it.
11768 Pass `autoconf_dir' via options, not via invisible envvars.
11769 * lib/Autom4te/General.pm (&find_peer): Remove.
11770 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11771 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11772 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11773 find the executables for it.
11774 * tests/Makefile.am: Major cleanup. Too lazy to document...
11775 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11776 We only need PERL.
11777 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11778 indeed related to running the test suite, while passing
11779 --autoconf-dir and others is related to running non installed
11780 Autoconf executables. So don't do that, leave it to...
11781 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11782 * tests/autoscan: New.
11783 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11784 refer to library files: rely on --language.
11786 2001-08-29 Akim Demaille <akim@epita.fr>
11788 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11789 s/--set/--language/.
11791 2001-08-29 Akim Demaille <akim@epita.fr>
11793 * doc/autoconf.texi: Strip the @nodes.
11794 Suggested by Paul Eggert.
11795 (Initializing configure): Typo.
11797 2001-08-29 Akim Demaille <akim@epita.fr>
11799 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11800 Suggested by Paul Eggert.
11802 2001-08-29 Akim Demaille <akim@epita.fr>
11804 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11805 download in a tmp dir.
11807 2001-08-29 Akim Demaille <akim@epita.fr>
11809 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11810 case insensitive OSes out there :(
11811 From Tim Van Holder.
11813 2001-08-29 Akim Demaille <akim@epita.fr>
11815 * lib/autom4te.in: New.
11816 * lib/Makefile.am (edit, autom4te.cfg): New.
11817 * bin/autom4te.in (BEGIN): Simplify.
11818 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
11819 (&load_configuration): New. Use it.
11820 (&parse_args): Support --mode, --set, and --melt.
11821 * bin/autoconf.in: Simplify and adjust.
11822 * tests/Makefile.am (AUTOMAKE): Use --set.
11823 * tests/atlocal.in: Adjust.
11824 * BUGS: distcheck and check are weak.
11826 2001-08-29 Akim Demaille <akim@epita.fr>
11828 * lib/autotest/general.m4: Use
11829 foo=`(command) 2>/dev/null`
11830 not
11831 foo=`command` 2>/dev/null
11832 (at-devnull): Rename as...
11833 (AT-devnull): this.
11834 (--clean): Remove AT-* files too.
11835 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11836 Reported by Nicolas Joly.
11838 2001-08-28 Akim Demaille <akim@epita.fr>
11840 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
11841 quotes inside single quotes.
11842 Reported by Nicolas Joly.
11844 2001-08-28 Kevin Ryde <user42@zip.com.au>
11846 * doc/autoconf.texi (Function Portability): Mention C right shifts.
11848 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
11850 * lib/autotest/general.m4: Reword some messages.
11851 (AT_INIT): Check for the `times' builtin before using it.
11852 Support test ranges as arguments to the testsuite.
11853 Have -e imply -d as the help text suggested.
11855 2001-08-27 Akim Demaille <akim@epita.fr>
11857 * Makefile.maint: Formatting changes.
11858 (do-po-update, po-update, cvs-update, update): New targets.
11859 (AMTAR): Remove.
11861 2001-08-27 Akim Demaille <akim@epita.fr>
11863 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

11866 <AUTOTEST_PATH>: May contain absolute dir names.
11868 2001-08-27 Akim Demaille <akim@epita.fr>
11870 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11871 Support `VAR=VAL' as arguments.
11872 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
11873 may be set via the command line.
11875 2001-08-27 Akim Demaille <akim@epita.fr>
11877 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
11878 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
11879 first the build dirs, then the src dirs.
11880 * configure.ac (AC_CONFIG_TESTDIR): Adjust.
11882 2001-08-27 Akim Demaille <akim@epita.fr>
11884 * lib/autotest/general.m4 (AT_INIT): Output the definition of
11885 at_data_files earlier.

11889 2001-08-27 Akim Demaille <akim@epita.fr>
11891 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11892 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11893 readable.
11894 Adjust callers.
11895 * doc/autoconf.texi (Configuration Actions): Document the vars
11896 available in commands.
11897 Emphasize the risks of collisions in init-cmds.

11901 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
11902 (Initializing configure): this new node.
11904 2001-08-27 Akim Demaille <akim@epita.fr>

11917 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

11927 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
11928 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
11929 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11930 -> ac_dir).
11931 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11932 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11934 2001-08-27 Akim Demaille <akim@epita.fr>

11959 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
11960 (AMTAR): Help automake define it.
11961 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
11962 needed, 1.5 can have a macro and a target with the same name.
11963 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
11964 * m4/strip.m4: New.

11977 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
11978 Adjust callers.
11979 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11980 the name of the directory they're in, instead of the filename,
11981 since version.m4 is now in m4sugar, but m4_acversion must not be
11982 classified as an Autoconf macro.
11983 ($input_m4): Don't qualify the path to m4sugar.
11984 Rather, pass autoconf_dir to m4.
11985 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
11986 * tests/suite.at: Require 2.52c.
11988 2001-08-27 Akim Demaille <akim@epita.fr>

12000 of config.log on traps.
12001 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
12002 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
12003 for config.status'.
12004 Open the log as soon as possible.
12005 Use the same log introduction as configure's.
12007 2001-08-22 Paul Eggert <eggert@twinsun.com>
12009 * doc/autoconf.texi (Indices): New node.
12010 Move indices out of the top level menu and into this submenu.
12012 2001-08-22 Akim Demaille <akim@epita.fr>
12014 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12015 AC_TRY_COMMAND.
12016 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.

12073 2001-08-20 Akim Demaille <akim@epita.fr>
12075 Info readers seem to need `Index' in the index node title :(
12077 * doc/autoconf.texi: Reverse the 2001-08-15 change which
12078 simplified index node names.

12122 2001-08-20 Akim Demaille <akim@epita.fr>
12124 Huh!?!?! There are still some user EOF tags used, which prevents
12125 their use in AC_CONFIG_COMMANDS for instance...
12127 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
12128 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

12191 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

12207 2001-08-17 Akim Demaille <akim@epita.fr>
12209 * doc/autoconf.texi: Work around Texinfo buglets.
12210 (Transformation Rules): One example is enough, users are expected
12211 to have their brains on. And BTW, use DESTDIR.
12212 (dvar): New macro. Use it.
12214 2001-08-17 Akim Demaille <akim@epita.fr>
12216 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

12222 * bin/autom4te.in: --normalize is a new option.
12223 * bin/autoconf.in: Use it.

12256 value.
12257 From Kevin Ryde.
12259 2001-08-15 Akim Demaille <akim@epita.fr>
12261 * Makefile.maint (CVS): New.
12262 (local-check): Run changelog-check. last.
12263 (alpha): Don't depend upon local-check, since...
12264 (cvs-dist): depends upon it.
12266 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
12268 * tests/Makefile.am: Use a clean-local rule to remove
12269 autom4te.cache (it's a directory, not a file.
12270 * Makefile.am: Ditto (but maintainer-clean-local).
12272 2001-08-15 Akim Demaille <akim@epita.fr>
12274 * bin/autom4te.in (@m4_warning): New.
12275 (&handle_m4): Use it.
12276 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12277 warnings are issued at each run.
12278 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12279 is in the src tree.
12281 2001-08-15 Akim Demaille <akim@epita.fr>
12283 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
12284 don't waste time running `autoupdate --version' works.
12285 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
12287 2001-08-13 Akim Demaille <akim@epita.fr>
12289 * doc/autoconf.texi (ma): Rename this index as...

12312 * doc/autoconf.texi, doc/install.texi: Add a copyright notice

12346 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12348 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12349 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12350 * doc/autoconf.texi (C Compiler Characteristics): Update
12351 documentation for AC_C_BIGENDIAN.
12353 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12355 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12356 magic values from an object file when cross-compiling.
12357 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12359 2001-08-10 Akim Demaille <akim@epita.fr>
12361 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12362 effects.
12363 Suggested by Russ Allbery.
12365 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12367 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12368 current $prefix to the sub-configures.
12370 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12372 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12373 extension (needed on BeOS). Reported by Guido van Rossum.
12375 2001-08-09 Akim Demaille <akim@epita.fr>
12377 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12379 2001-08-07 Akim Demaille <akim@epita.fr>
12381 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12382 removed.
12383 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12384 No need to remove the files before and after the each test, before
12385 each test and at the end of the suite is enough.
12386 Display only the children `times', not the shell's.
12387 If the test failed or was skipped, at-times is not available.
12389 2001-08-07 Akim Demaille <akim@epita.fr>
12391 Always produce testsuite.log, including when there are no
12392 failures. This helps getting information on skipped tests, and
12393 duration of the tests. Err, implement the latter btw.
12395 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12396 Dump information on the first run of each test.
12397 (AT_CLEANUP): Create `at-times' containing the duration of the
12398 test group.
12400 2001-08-07 Akim Demaille <akim@epita.fr>
12402 The use of `dumpstat' revealed that `len' was used although it
12403 should not. m4_text_wrap was using it, but in the Autoconf world
12404 where it is legal. Hence (i) test M4sh in its own world, not
12405 Autoconf's, and (ii), ahem, fix the bug :)
12407 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12408 does not like `' instead of [].
12409 (AT_INIT): Forbid `^_?AT_'.
12410 And don't output such tokens.
12411 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12412 `script.as', and `autom4te.cache'.
12413 Remove `empty' and `macro' which are no longer used.
12414 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12415 * tests/m4sugar.at: Use it.
12416 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12418 2001-08-07 Akim Demaille <akim@epita.fr>
12420 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12422 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12424 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12426 2001-08-04 Akim Demaille <akim@epita.fr>
12428 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12429 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12430 AC_TRY_LINK.
12431 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12432 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12433 (AC_F77_MAIN): Likewise.
12435 2001-08-04 Akim Demaille <akim@epita.fr>
12437 Don't rely on M4sugar outputting the patterns in files, since we
12438 might process the output _without_ running m4, hence without these
12439 files.
12441 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12442 * bin/autom4te.in (@Request::includes): Remove, unused.
12443 (@Request::source): Rename as...
12444 (@Request::input): this.
12445 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12446 (&handle_output): Fetch the patterns from the traces.
12447 `$forbidden' and `$allowed' are constant: use m//o.
12448 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12449 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12451 2001-08-04 Akim Demaille <akim@epita.fr>
12453 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12454 autoconf', i.e., in addition to caching traces, cache the output.
12456 * bin/autom4te.in (Request::cache): Rename as...
12457 (Request::id): this.
12458 ($cache, $icache, $tcache, $ocache): New.
12459 (&handle_m4): Save M4 output in the cache instead of $tmp.
12460 (&handle_output): Adjust.
12461 (&up_to_date_p): Check that the output cache is up to date too.
12462 (top level): Run `&handle_m4' iff force or the cache is invalid.
12463 Run `&handle_output' if the output cache is more recent.
12465 2001-08-04 Akim Demaille <akim@epita.fr>
