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

465 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
467 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
468 Require that long long int be at least 64 bits wide. C99 requires
469 this and enough programs depend on it so we should check for it.
470 Bruno Haible reports in
471 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
472 that long long int is 32 bits wide with some nonstandard compilers.
473 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
475 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
477 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
478 to a nonexistent file, so that we don't have to worry about
479 a local site configuration that doesn't use /usr/local.
480 Problem reported by Keith Marshall in
481 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
483 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
485 * doc/autoconf.texi: Be more consistent about using @acronym with
486 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
487 quite right (it talked about "OSF/Tru64", even though the
488 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
489 and it even mentioned "OSF 4"!) and at this point there's little
490 reason to talk about OSF any more, since it died in 1994.
491 (Specific Compiler Characteristics): Simplify example of
492 negative-size array.
493 (File Descriptors): Reorder to make the text flow better.
494 Remove joke about "appreciate the various levels"; I didn't get it.
495 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
496 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
497 (File Descriptors, Limitations of Usual Tools):
498 Tone down the advice against renaming or removing open files.
499 (Limitations of Usual Tools): Add a new section, on 'rm'.
501 2006-06-26 Stepan Kasal <kasal@ucw.cz>
503 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
504 -lXt in LIBS, idea from Karsten Hopp; this was due since
505 this change:
507 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
508 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
509 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
510 (which belong to Xt, not X itself). See Debian bug 327655.
512 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
514 * configure.ac (AC_INIT): Bump to 2.60a.
515 * NEWS: Update.
517 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
519 Version 2.60.
521 * configure.ac, NEWS: Update.
523 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
525 * config/texinfo.tex: Sync from upstream.
527 * bin/autom4te.in (handle_traces): Transform the `@S|@'
528 quadrigraph correctly in traces.
530 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
531 Fix typos.
533 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
534 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
535 not defined.
536 * doc/autoconf.texi (Changed Directory Variables): New node,
537 to document the whole `datarootdir' business a bit better.
538 * NEWS: Update.
539 * tests/torture.at (datarootdir workaround): Extend test.
540 Prompted by report by Alexandre Julliard.
542 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
544 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
545 when using default mode of IBM C 6 for AIX. Problem and two-line
546 fix reported by Larry Jones.
548 2006-06-22 Alexandre Julliard <julliard@winehq.org>
550 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
551 about literal '${datarootdir}' if a definition is found in the
552 output file.
554 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
556 * NEWS: Use "M4" rather than "m4" when appropriate.
557 Problem reported by Eric Blake.
558 * doc/autoconf.texi: Likewise.
559 Use @acronym around BSD, GCC, and GNU when appropriate.
560 (Why GNU M4): Renamed from "Why GNU m4".
561 (Redefined M4 Macros): Mention that Posix
562 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
563 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
564 to int.
566 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
568 * bin/autom4te.in (handle_output): Do not forbid the empty
569 pattern.
570 * tests/tools.at (autoconf: the empty token): New test.
572 2006-06-20 Stepan Kasal <kasal@ucw.cz>
574 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
575 calls, so that we do not care whether they are LIFO or FIFO;
576 in the m4_wrap, do not check which diversion is the topmost
577 one, just check that the stack is balanced at the end.
578 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
579 base diversion forever--pop the previous diversion before
580 opening the new one; consequently, remove the m4_wrap call.
581 * lib/autotest/general.m4 (AT_INIT): Likewise.
582 * tests/m4sugar.at: Do not use
583 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
585 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
586 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
588 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
589 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
590 Rework example of m4wrap token-pasting trouble so that it doesn't
591 care whether it's LIFO or FIFO.
592 Fix some "contrary to"s that are awkward in English.
594 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
596 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
597 to `yes' instead of `int$1_t' if the type is found, for more
598 consistent configure output (where $1 is the number of bits).
599 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
600 Suggested by Bruno Haible.
602 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
603 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
604 with system headers. Report by Bruno Haible.
606 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
608 * config/config.guess, config/config.sub: Sync from upstream.
610 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
611 in order to avoid picking up an older installed frozen m4sh.m4f.
612 Besides an outdated shell startup, this could have been created
613 by an earlier M4 version with incompatible frozen file format.
615 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
617 * README: Recommend m4 1.4.4 instead of 1.4.3..
618 * doc/autoconf.texi: Likewise.
619 (Special Chars in Names): Say that $(.FOO) is portable, as
620 suggested by Stepan Kasal.
621 (Installation Directory Variables, Build Directories):
622 (Automatic Remaking, Subdirectories, Fortran Compiler):
623 (Making testsuite Scripts, Defining Directories):
624 Quote variable usages better.
625 (Making testsuite Scripts): Add clean-local rule to makefile
626 snippet, by Eric Blake.
627 (Installation Directory Variables): Fix table item font.
628 Reword slightly to clarify. Generalize advice about
629 not using special characters to include all file-related
630 vars, not just VPATH.
631 (Special Chars in Variables): Warn about special characters in
632 $(srcdir) too.
633 (Assignments): Clarify default-value example as suggested by
634 Ralf Wildenhues in
635 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
636 (Special Shell Variables): Note leading ./ or ../, as suggested
637 by Eric Blake.
638 (Limitations of Builtins): Under cd, warn about CDPATH.
639 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
640 Ralf Wildenhues.
642 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
644 * doc/autoconf.texi (Configuration Actions): Remove duplicate
645 `@var', for texi2html.
646 (Systemology): Some more word wrapping, for DVI output.
647 (autom4te Invocation): The short option for `--melt' is `-M',
648 not `-m'.
650 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
652 * doc/autoconf.texi: More formatting and English tweaks,
653 many suggested by Ralf Wildenhues.
654 Reword to avoid "@code{...}'s" and the like, since it's ugly
655 with Emacs info mode. discontents -> woes.
656 Put a few "will"s back. time stamp -> timestamp.
657 side-effect -> side effect.
659 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
661 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
662 Warn about $@ not persisting. Problem reported by Julien Danjou in
663 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
664 (Special Chars in Names): Renamed from Leading _ in Macro Names.
665 Mention other special chars, too.
667 2006-06-14 Eric Blake <ebb9@byu.net>
669 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
671 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
673 * doc/autoconf.texi: Some systematic minor improvements, as
674 follows. Use "makefile" when talking about makefiles
675 generally (which might be named "makefile" or "Makefile" or even
676 "foo.mk"), "Makefile" when talking about a specific makefile
677 called "Makefile". This unclutters the text from weird quotes
678 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
679 values" rather than "@var{foo}s" and similar constructs containing
680 "}s". Use "Make rules" rather than "Makefile rules". Minor
681 English-language improvements. Change the prefix "sub-" to "sub"
682 and "re-" to "re".
683 Put blank lines around examples more consistently.
684 Avoid "rather" and "very" as intensifiers.
685 Avoid "will" as an auxiliary.
686 (Limitations of Make): Split this node into....
687 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
688 (Leading _ in Macro Names, Backslash-Newline-Newline):
689 (Backslash-Newline Comments, Long Lines in Makefiles):
690 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
691 (obj/ and Make, make -k Status, VPATH and Make):
692 (VPATH and Double-colon, $< in Explicit Rules):
693 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
694 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
695 New nodes, resulting from splitup of Limitations of Make.
696 All cross-references changed. Raise the top node from
697 a section to a chapter, and all subnodes accordingly.
698 Redo the introductory wording to match the new organization.
699 (Installation Directory Variables): Use an example that is
700 closer to what Autoconf actually does. Mention that VPATH's
701 value should not contain metacharacters or white space.
702 (Fortran Compiler): Fix a VPATH bug in an example.
703 (Leading _ in Macro Names): Mention that this problem is no longer
704 of practical concern.
705 (VPATH and Make): Reword the advice to make it clearer
706 that Autoconf and Automake support VPATH in non-GNU make, but
707 many packages have bugs in this area.
708 ($< in Explicit Rules): Refer to Build Directories rather
709 than using a (non-VPATH-safe) example.
710 (Automatic Rule Rewriting): Mention the sort of disaster that
711 can ensue with Solaris-style rule rewriting with VPATH.
713 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
715 * doc/install.texi (Compilers and Options): Weaken the
716 suggestion to use GNU make for VPATH builds.
718 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
719 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
721 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
722 in regular expression.
724 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
726 * doc/autoconf.texi (Installation Directory Variables):
727 Drop extra @samp from `@table @samp' item.
728 (Limitations of Usual Tools): Comment fix.
729 Do not nest @samp just to point to other table items.
730 (Writing testsuite.at) <AT_CHECK>: The second argument to
731 `@dvar' is already @samp'ed.
732 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
733 do not use @var in the second argument.
735 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
737 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
738 $as_shell.exe too. Problem reported by Andreas Buening in
739 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
741 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
743 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
744 `unused variable' compiler warning, for `-Wall -Werror'.
745 Reported by Jaap Haitsma in
746 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
748 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
750 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
751 case the compiler dumps core. Problem reported for
752 OpenServer 5.0.7 by Tim Rice in
753 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
754 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
755 Likewise.
757 2006-06-06 Tim Rice <tim@multitalents.net>.
759 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
760 "ERROR" only shows up in "make check" output if there is an
761 error.
763 2006-06-06 Eric Blake <ebb9@byu.net>
765 * tests/tools.at (automatically allowed tokens): Fix typo.
767 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
769 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
771 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
772 typically overflows on x86 CPUs, even though the C standard
773 requires otherwise.
775 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
777 * configure.ac (AC_INIT): Bump to 2.59e.
778 * NEWS: Update.
780 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
782 Version 2.59d.
784 * config/texinfo.tex: Sync from upstream.
786 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
787 seen, invoke libtoolize with `--ltdl' argument.
788 * lib/autom4te.in (Autoreconf-preselections): Adjust.
789 * NEWS: Update.
790 Suggested by Eric Blake.
792 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
794 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
795 reported by Ralf Wildenhues.
796 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
798 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
800 * THANKS: Update.
802 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

808 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
809 message issued by AC_REQUIRE.
810 * tests/m4sugar.at: Check m4_require's error message.
811 * tests/base.at: Check AC_REQUIRE's error message.
812 * tests/local.at (AT_CHECK_M4): New macro, almost identical
813 to...
814 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
815 AT_CHECK_M4.
816 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
817 `expout' as the last parameter.
818 * tests/tools.at: Adapt to the above change.
820 2006-06-04 Stepan Kasal <kasal@ucw.cz>
822 * doc/autoconf.texi (Limitations of Usual Tools): Correct
823 information about race-free implementations of mkdir.
825 2006-06-04 Eric Blake <ebb9@byu.net>

830 * doc/autoconf.texi (autom4te Invocation): Likewise.
832 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
834 * NEWS: GNU make now recommended for VPATH builds.
835 Mention that some macros are now documented to be obsolescent.
836 * doc/autoconf.texi:
837 Prefer "current" to "modern" to describe
838 currently-used (albeit perhaps old-fashioned) hosts.
839 Mention which ancient features no longer need to be worried about.
840 setgid -> set-group-ID
841 setuid -> set-user-ID (these are the Posix terms)
842 Fix some misuses of "only".
843 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
844 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
845 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
846 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

850 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
851 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
852 Mention that these macros are obsolescent.
853 (Installation Directory Variables): shall -> should
854 (File Descriptors): Mention that 0, 1, 2 might get reopened.
855 Mention that it's now safe to use 3 and 4.
856 (Limitations of Usual Tools): cp -r is now specified by Posix.
857 Omit longwinded and obsolescent discussion of cp -f.
858 Modernize discussion of expr, ls.
859 (Limitations of Make): Modernize discussion of VPATH builds.
860 Mention $? as a workaround in some cases.
861 * doc/install.texi (Basic Installation):
862 Mention "./configure; make; make install" first. Be more
863 specific about why this file is generic. Remove unnecessary
864 parens. Remove misleading "only". Remove obsolete advice
865 about csh. Don't say "configure" takes awhile; say it
866 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
867 and CC=c99 rather than CC=c89, as these are blessed by current
868 Posix. Recommend GNU make if doing a VPATH build.
870 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
872 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
873 examples involving shell prompts.
875 2006-06-02 Stepan Kasal <kasal@ucw.cz>
876 and Paul Eggert <eggert@cs.ucla.edu>
878 * doc/autoconf.texi (Here-Documents): Add details about the
879 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
880 use "here-documents" instead of "here documents".

884 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
886 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
888 * doc/autoconf.texi (File System Conventions): Warn about ":"
889 anywhere in directory names.
891 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
893 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
894 about quoting the case statement, just in case.
895 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
896 was fixed in ksh93g; reported by Ralf Wildenhues.
898 2006-05-31 Stepan Kasal <kasal@ucw.cz>
900 * doc/autoconf.texi (System Services): Do not document
901 overriding EXEEXT via ac_cv_exeext=ext.

910 argument with leading hyphen. Problem reported by Paul Eggert.
912 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
914 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
915 about quoting ac_try: quote all of it, if any of it seems suspicious.
916 This means we don't have to worry about ${ or sed any more.
917 Also, double-quote the case statement, to work around misuses via
918 underquoting as reported by Ralf Wildenhues in
919 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
920 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
921 undocumented and dangerous macro.
922 Problem reported by Ralf Wildenhues in
923 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
925 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
927 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
928 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
929 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
931 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
933 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
934 since evidently some packages rely on the old, broken behavior.
935 Problem reported by Ralf Wildenhues in
936 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
937 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
938 pre-2006-05-26 definitions, but leave in the comments that
939 these macros are dangerous and should not be used.
940 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
941 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
942 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
943 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
944 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
946 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
948 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
949 the use of 'tr', since this is our only use of 'tr'.
951 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
952 and Paul Eggert <eggert@cs.ucla.edu>
954 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
955 Don't assume 'grep' works on long lines, since AIX grep doesn't.
957 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
959 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
960 the output file in the `${datarootdir}' test.
962 2005-05-28 Stepan Kasal <kasal@ucw.cz>
963 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
965 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
966 mention of `datarootdir' in the input file(s), but literal
967 `${datarootdir}' in the output file, and we haven't warned yet,
968 then warn as well: the user may have (erroneously) used
969 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
970 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
971 * tests/torture.at (datarootdir workaround): Extend this test.
972 * NEWS: Update.
974 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
975 and Paul Eggert <eggert@cs.ucla.edu>
977 * doc/autoconf.texi (autoheader Invocation): The first argument to
978 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
979 alternatives and clear up the language a bit.
981 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
983 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
984 ac_config_guess, ac_config_sub, ac_configure.
985 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
986 Fix typo that prevented an unnecessary space from being removed.
987 Problems reported by Ralf Wildenhues in:
988 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
990 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
992 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
993 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
994 Don't use the term "thread-safe" to talk about mkdir race
995 conditions, since the problem is more a process than a thread
996 issue. Problem reported by Stepan Kasal in:
997 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
998 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
999 the test for 'install' more closely. Look at MKDIR_P first.
1000 Look in the PATH, and at /opt/sfw/bin.
1001 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1002 Don't bother to try mkdir -p, since we already check mkdir --version;
1003 just look at the version number. (There's no easy way to check
1004 for race-free implementations.)
1005 * tests/tools.at (autoconf: subdirectories): Adjust to above
1006 changes, since MKDIR_P now might end in "/mkdir -p".
1008 * doc/autoconf.texi (autoheader Invocation): Mention that the
1009 first arg of AC_DEFINE_UNQUOTED must be a literal.
1010 Problem reported by Ben Pfaff in
1011 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1013 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1014 * doc/autoconf.texi (Special Chars in Variables): New section.
1015 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1016 (Installation Directory Variables): Quote $(datadir) better.
1017 (Limitations of Builtins): Describe some of eval's trickiness.
1019 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1020 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1021 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1022 in front of every arg, not just trailing args. Quote apostrophes.
1023 (_AC_EVAL_ECHO): New macro.
1024 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1025 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1026 removed.
1027 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1028 exposed by quoting of eval argument. Put the command on line line
1029 so it logs better.
1030 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1031 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1032 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1033 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1034 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1035 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1036 Use eval more safely.
1037 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1038 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1039 to be replaced.
1040 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1041 lines, exposed by quoting of eval argument.
1043 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1044 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1046 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1047 initialization of `ac_cv_exeext', do not override it if it was
1048 already set, unless it was set to `no', for compatibility with
1049 Autoconf-2.13, and comment this.
1050 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1051 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1052 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1053 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1054 Document that this test may be overridden by setting
1055 `ac_cv_exeext'.
1057 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1059 Revert these two patches:
1061 2006-04-06 Eric Blake <ebb9@byu.net>
1062 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1063 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1064 2006-04-01.
1066 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1067 Clean up _AC_COMPILER_EXEEXT* macros.
1068 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1069 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1070 ac_file to the name of the default output file and call
1071 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1072 initial `rm' of the candidate files...
1073 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1074 the same list in subsequent `rm' calls, and for the temporary
1075 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1076 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1077 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1078 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1079 no longer needed) by libtool. Make it a cache check.
1080 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1081 copied here by mistake.
1082 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1083 _AC_COMPILER_EXEEXT.
1084 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1085 _AC_COMPILER_OBJEXT directly.
1086 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1088 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1090 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1091 Fix description of how the buggy `sed' works.
1093 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1095 Sync from Automake:
1097 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1098 ENOLCK. Only mention `make -j' when applicable. Only raise
1099 fatal errors when `make -j' is involved. Improve error message.
1101 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1103 * doc/autoconf.texi (Here-Documents): We now know more about
1104 the variable expansion in here documents bug.
1105 Thanks to Tim Rice and Stepan Kasal.
1107 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1108 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1110 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1112 * tests/autotest.at (Multiline command from M4 expansion):
1113 No failure to be expected if the shell quotes newlines in
1114 commands in the `set -x' output. Report by Tim Rice.
1115 * THANKS: Update.
1117 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1119 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1120 expansion in the here-documents used by config.status, as that
1121 runs afoul of the Korn shell version M-12/28/93d bug described in
1122 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1123 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1124 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1126 2006-05-23 Jim Meyering <jim@meyering.net>
1128 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1129 Fix typo introduced with 2006-04-02 change. It reversed the sense
1130 of the test.
1132 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1134 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1135 ac_dB slightly, to save bytes in the script.
1136 Max out at 50 lines, rather than 96; this is more likely
1137 (though not guaranteed) to avoid obscure 'sed' failures.
1139 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1141 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1142 `tr -d -' as bad option argument. Work around this by deleting
1143 an unrelated character.
1144 Report by Tim Rice <tim@multitalents.net>.
1146 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1147 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1148 Stepan Kasal <kasal@ucw.cz>
1150 * doc/autoconf.texi (Particular Programs): Do not promise that
1151 we always prefer the GNU version of the program, and that we
1152 search according to PATH; both rules can have exceptions.
1153 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1154 AC_PROG_SED. Move descriptions of limitations
1155 to the Limitations of Usual Tools section.
1156 (Limitations of Usual Tools) <sed>: Mention script length
1157 limitations with Solaris /usr/ucb/sed.
1158 <grep>: Fix wording for empty alternative. Mention that -c and
1159 -l should not be combined, and that -E and -F should not be
1160 combined.
1162 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1163 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1165 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1166 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1168 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1170 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1171 AC_DEFINE is now passed to m4_pattern_allow.
1172 * NEWS: Mention that; likewise for AC_SUBST.
1173 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1174 the parameter to m4_pattern_allow.
1175 * tests/tools.at: Add a check for that.
1177 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1179 * lib/autoconf/status.m4: Fix typos.
1181 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1183 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1184 only the files that this macro generates.
1186 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1188 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1189 the HP-UX sed limitation of 99 commands, labels do not count.
1190 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1191 in the comment.
1192 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1194 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1196 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1197 Import the following fix from coreutils:
1199 2006-01-13 Jim Meyering <jim@meyering.net>
1201 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1202 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1203 not double-quote uses of that variable, to accommodate the rare
1204 case in which getmntent is available in none of the libraries
1205 checked. This happens at least on FreeBSD 5.0.
1207 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1209 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1210 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1211 some other programs unwisely rely on these undocumented vars.
1212 But put in warning comments about them.
1213 Problem reported by Ralf Wildenhues in
1214 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1215 * NEWS: Document that these variables are intended to go away.
1217 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1219 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1220 and set the language to C++ (analogous to the equivalent Fortran
1221 tests).
1223 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1224 * doc/autoconf.texi (C++ Compiler): Document it.
1225 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1226 * NEWS: Update.
1228 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1230 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1231 that caused config.status to generate 100-command sed scripts; the
1232 portable limit is 99.
1234 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1236 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1237 variable `ac_d' instead of `d' to avoid infringing namespace.
1238 Report by Ralf Menzel.
1240 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1242 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1243 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1244 * tests/tools.at (autoconf: subdirectories): New test, taken from
1245 the corresponding problem report by Ralf Wildenhues in:
1246 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1248 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1249 Quote some uses of shell variables if they might suffer unexpected
1250 globbing. This doesn't fix all instances of quoting problems that
1251 I found, just the easy ones that look safe.
1252 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1253 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1254 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1255 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1256 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1257 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
1258 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
1259 Likewise.
1260 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
1261 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1263 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1265 * bin/autoreconf.in ($help): Reword according to the manual.
1266 Suggested by Olly Betts.
1268 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1269 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1271 * bin/autoreconf.in: Pass the directory argument to
1272 `require_configure_ac'. Fix comment.
1273 * tests/torture.at (Configuring subdirectories): Expose this.
1274 Reported by Olly Betts.
1276 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1278 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1279 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1280 Automake as follows:
1282 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1283 `$configure_in' instead of `configure.in', to preserve
1284 directory component.
1286 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1288 * config/config.guess, config/config.sub, config/texinfo.tex,
1289 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1291 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1293 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1294 test for C99 conformance; (bool) 0.5 is an integer constant
1295 expression, but (bool) -0.5 is not. Problem reported by Fedor
1296 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1298 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1300 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1301 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1302 Warn about obsolete install-sh files. Remove stray sentence
1303 fragment and fix cross reference.
1304 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1305 install -d; this undoes the 2006-05-10 change.
1306 (MKDIR_P): Mark with AN_MAKEVAR.
1307 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1308 that we don't require $INSTALL to be thread-safe. Move comments
1309 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1310 of AC_PROG_INSTALL. Output a message saying that we're checking
1311 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1312 MKDIR_P instead of AC_SUBST.
1313 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1314 Special magic for MKDIR_P, too.
1315 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1316 a dnl.
1317 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1319 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1321 Sync from Automake, as follows:
1323 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1324 * config/install-sh: Initialize IFS, so field splitting isn't
1325 turned off later.
1326 * config/mkinstalldirs: Likewise.
1327 * config/missing: Remove superfluous quotes. Replace all uses of
1328 `[' by `test', for consistency, and for..
1329 * config/missing (sed_minuso, sed_output): New variables.
1330 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1331 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1332 Fixes `missing' to detect `--output' for help2man. Fixes
1333 PR automake/483. Report by Dennis J. Linse.
1334 (autom4te): Document in `missing --help'.
1336 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1338 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1339 * config/install-sh: Don't use 'path' to talk about file names,
1340 as per GNU coding standards. Close a race condition reported by Ralf
1341 Wildenhues and Stepan Kasal. There is still a race condition
1342 on hosts that predate Posix 1003.1-1992, but we can't help this.
1343 Don't mishandle weird characters like space on pre-Posix hosts.
1344 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1345 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1346 AC_PROG_MKDIR_P from AS_MKDIR_P.
1347 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1348 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1349 earlier editions are not (including Automake 1.8.3).
1350 Do not suggest mkinstalldirs for thread-safety.
1351 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1352 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1353 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1354 presence of special characters and race conditions.
1355 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1356 in Autoconf's name space.
1358 2006-05-10 Bruno Haible <bruno@clisp.org>
1359 and Paul Eggert <eggert@cs.ucla.edu>
1361 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1362 from Automake with minor changes.
1363 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1365 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1367 * config/install-sh: Update to Automake CVS version, as follows:
1368 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1369 * lib/install-sh: Simplify the expr implementation of dirname.
1370 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1371 * lib/install-sh: Handle --, and diagnose unknown options.
1373 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1375 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1376 `./autom4te' to create `./testsuite', since the `all' target
1377 will ensure its presence, but `installcheck' should not create
1378 the uninstalled wrappers.
1380 * tests/torture.at (Unusual Automake input files): Skip if we
1381 detect automake < 1.8.
1383 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1385 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1386 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1387 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1388 * NEWS: Update.
1390 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1392 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1393 munge (multiple) white space and other oddities.
1394 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1395 single quotes in variable assignment.
1396 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1397 and similar failures by adding multiple spaces, tabs, and other
1398 special characters.
1399 Report and different test suggested by Francesco Romani
1400 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1402 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1403 single quotes, we only need to search for single quotes; this
1404 both simplifies the search pattern, and makes us less
1405 susceptible to `echo' variations for arguments not containing
1406 single quotes.
1407 (_AC_ARG_VAR_VALIDATE): Likewise.
1409 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1411 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1412 `$*' and IFS concatenation issue with traditional shells and
1413 bash-2.04. Report by Seanster@Seanster.com.
1415 2006-05-03 Bruno Haible <bruno@clisp.org>
1417 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1418 precisely which Mac OS X versions have the od problem.
1420 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1422 * doc/autoconf.texi: Use @option systematically.
1424 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1425 and Bruno Haible <bruno@clisp.org>
1427 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1428 about 'od'.
1429 (Integer Overflow): Mention the special case of integer division
1430 overflow.
1432 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1434 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1435 traditional shells like the Solaris one that do not use the
1436 first IFS character for assembling `$*'.
1437 Prompted by a related report from autoconf_bug@nro.ca.
1439 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1440 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1442 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1443 Mention more problems with the -e option.
1445 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1447 * NEWS: Typo.
1448 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1450 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1451 in URLs to improve DVI formatted output (requires texinfo 4.6).
1452 (System Services, Systemology, Shellology): Likewise.
1453 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1454 output.
1456 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1457 continuous text.
1458 (Runtime): Fix macro argument names to match description:
1459 `action-if-found' -> `action-if-true' and similarly.
1460 (Obsolete Macros): Likewise.
1461 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1462 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1463 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1465 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1467 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1469 * ChangeLog: Typo.
1470 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1471 DVI output.

1476 /bin/sh set unsorted output.
1477 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
1478 * tests/local.at: Likewise.
1480 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
1482 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1483 (Integer Overflow, Null Pointers, Buffer Overruns):
1484 (Floating Point Portability, Exiting Portably): New sections.
1485 (Writing Test Programs): Fix some langauge. Recommend exiting
1486 with status 1, not merely nonzero. Clarify exit declaration.
1487 (Run Time): Move C exit status stuff to new Exiting Portably section.
1488 (Systemology): Mention Posix and levenez. Update v7 reference.
1489 (Portable Shell): Mention the Posix shell.
1491 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1493 * bin/autoconf.as (me): Replace by as_me.
1495 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1497 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1498 since as_me isn't set yet.
1500 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1502 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1503 a few minor bugs in this area.
1505 * doc/autoconf.texi (Programming in M4sh): Comment out the
1506 documentation of AS_BASENAME, for now.
1507 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1508 (Limitations of Builtins) <basename>: Do not refer to
1509 AS_BASENAME.
1510 * bin/autoconf.as (me): Don't use AS_BASENAME.
1511 (dir): Remove the unused variable.
1512 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1513 AS_DETECT_REQUIRED. All uses changed.
1514 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
1515 All uses changed.
1516 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1517 (AS_BASENAME): Use "basename --" to protect against leading "-".
1518 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1519 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1520 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1521 (_AS_DIRNAME_PREPARE): Likewise.
1522 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1523 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1524 (AS_DIRNAME): Use "dirname --".
1526 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1528 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1529 of "run time" and "run-time" changed to "runtime", for consistency.
1530 * lib/autoconf/fortran.m4: Likewise (in comment).
1531 * lib/autoconf/functions.m4: Likewise.
1532 * lib/autoconf/general.m4: Likewise.
1533 * lib/autoconf/headers.m4: Likewise.
1535 * doc/autoconf.texi (Run Time): Document the exit status situation
1536 with more accuracy and detail.
1538 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1540 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1541 Archive is not officially `GNU' any more. Update URL.
1542 (Defining Directories): Likewise
1543 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1545 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1547 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1548 newline from the `trap' code to finish `config.log'; the NetBSD
1549 /bin/sh resets the exit status after an empty command, as
1550 documented in doc/autoconf.texi.
1551 Reported by Dalibor Topic <robilad@kaffe.org>.
1553 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1555 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1556 Suggested by Bruno Haible.
1558 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1560 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1561 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1562 Instead, just list the shells that we know work.
1563 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1564 changed. Be more cautious about the _cv_ variable.
1565 * tests/tools.at (Syntax of the shell scripts): Check the
1566 _cv_ variable once, at first, to avoid an internal autoconf error
1567 when sh -n does not work.
1569 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1571 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1573 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1575 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1576 use ">&-" since we're only 99.999% sure that this is portable,
1577 and since the MinGW bug is fixed in a different way.
1578 * lib/autotest/general.m4 (AT_INIT): Likewise.
1580 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1582 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1583 before opening config.log, to avoid hitting a bug on MinGW.
1585 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1587 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1588 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1589 This works around a MinGW bug reported by Eric Paire.
1590 Make sure that all writes to the log file append to it,
1591 rather than possibly losing data.
1592 * lib/autotest/general.m4 (AT_INIT): Likewise.
1594 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1596 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1597 description.
1599 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1601 * NEWS: Update.
1603 * configure.ac (AC_INIT): Bump to 2.59d.
1605 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1607 Version 2.59c.
1609 * Makefile.maint (news-date-check): Do not require a leading `*'
1610 before the release date in NEWS.
1612 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1613 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1615 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1616 the instantiated file do not contain the string 'datarootdir'
1617 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1618 @mandir@, replace the reference '${datarootdir}' by the value.
1619 * tests/torture.at (datarootdir workaround): New test.
1620 * NEWS: Advertise this temporary fixup.
1621 Based on a patch by Bruno Haible, reported and analyzed by
1622 Paul Eggert and Noah Misch.
1624 2006-04-12 Eric Blake <ebb9@byu.net>
1626 * tests/autotest.at (Debugging a failed test): Fix comment.
1628 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1630 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1631 all the changes since 2006-04-07.
1633 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1635 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1636 succeeded, but `ln -s file dir' failed, take care to remove the
1637 leftover target before the next test, to prevent its spurious
1638 failure; also make sure `ln file dir' works before selecting it.
1639 Thanks to Keith Marshall for pointing this out.
1640 * THANKS: Update.
1642 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1643 assignments in `at_debug_args', so that we put them correctly
1644 in the `run' script.
1645 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1646 Reported by Eric Blake.
1648 2006-04-11 Eric Blake <ebb9@byu.net>
1650 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1651 top-level tests after micro-suite has been run. Used in...
1652 (Debugging a successful test, Debugging script and environment),
1653 (Debugging a failed test): ...these new tests. The first of these
1654 is fixed by...
1655 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1656 macro, split out from...
1657 (AT_INIT): ...here, so that using -d also generates a run script.
1658 Document that -d inhibits top-level logging.
1659 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1660 inhibits top-level logging; debug scripts are created.
1662 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1663 check.
1664 * tests/autotest.at (Empty test, Empty check): New test to check it.
1666 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1667 from gcc.
1669 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1671 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1672 the files if a problem appears. Make the empty *.at files
1673 read-only, too. Proposed by Ralf Wildenhues.
1675 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1677 * config/Makefile.am: Add comment to force updated Makefile.in.
1679 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1680 space only patch to this file, this patch causes the Makefile.in
1681 files that include freeze.mk to be updated, and thus have a
1682 newer time stamp again, which in turn makes a pristine CVS
1683 checkout have correct time stamps.
1685 * Makefile.maint (cvs-sv): New macro, to be used..
1686 (config.guess-url_prefix, config.sub-url_prefix)
1687 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1688 point to CVS text checkout of Gnulib files.
1689 (copyright-check): Bump current year.
1690 (announcement): Do not hard-wire `./announce-gen'.
1691 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1692 correctly.
1693 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1694 `chmod +x'.
1695 (wget_files): Update config.guess, config.sub, texinfo.tex by
1696 `wget-update', now that their URLs work again.
1698 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1700 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1701 Problem noted by Paul D. Smith.
1703 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1705 * doc/autoconf.texi: Remove unused words from word list.
1706 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1707 .x-sc_trailing_space: New files.
1709 * doc/standards.texi: Sync from gnulib.
1711 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1712 `LIBOBJDIR' as experimental.
1714 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1715 with a target directory; it's internally implemented as `cp'
1716 anyway, but since Autoconf advertises the possibility to use
1717 a target directory when LN_S is `ln -s', we need to find out.
1718 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1719 analyzed by Keith Marshall <keith.marshall@total.com>.
1721 * THANKS: Update.
1723 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1725 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1726 confdefs.h as-is. In general, if it has backslash-newline or the
1727 like, then it doesn't work either to sort or to remove empty
1728 lines.
1730 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1732 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1734 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1736 * lib/autom4te.in (Automake-preselections): Preselect
1737 _AM_SUBST_NOTMAKE.
1739 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1741 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1742 apostrophe within a single-quoted string, as this is the usual
1743 tradition and is easier to read than '"'"'. Don't rely on the
1744 shell treating "$/" like '$/'. Use a more-consistent indenting
1745 style for the trap.
1747 2006-04-09 Eric Blake <ebb9@byu.net>
1749 * tests/autotest.at (Backquote command substitution),
1750 (Multiline backquote command substitution): Remove mistaken
1751 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1752 applied...
1753 (Parenthetical command substitution, Multiline parenthetical
1754 command substitution): here.
1756 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1758 Import macros from gnulib (often changing their name).
1760 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
1761 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
1762 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

1768 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
1769 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
1770 The manual mentions Gnulib more prominently.
1771 * doc/autoconf.texi (Gnulib): New node.
1772 (Pointers): Add Gnulib URL.
1773 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
1774 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1775 Gnulib section.
1776 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
1777 suggest a #define rather than a typedef for _Bool, and mention
1778 Gnulib rather than trying to substitute stdbool code.
1779 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
1780 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
1781 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
1782 AC_STRUCT_DIRENT_D_TYPE.
1783 (Particular Types): Mention stdint.h and inttypes.h as standard
1784 headers too.
1785 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1786 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1787 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1788 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1789 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1790 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1791 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1792 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1793 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1794 (Coding Style). Don't mention m4_expand_once.
1795 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
1796 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
1797 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
1798 (AC_CHECK_FUNCS): Use it.
1799 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
1800 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".

1802 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
1803 (AC_HEADER_ASSERT): New macro.
1804 (AC_HEADER_STDBOOL): Don't assume "#error" works.

1834 _AS_DETECT_BETTER_SHELL:
1836 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1837 skip nonexistent directories.
1838 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1839 only shell candidates which exist.
1840 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1841 * lib/autotest/general.m4 (AT_INIT): No need to give three
1842 parameters to _AS_PATH_WALK.
1844 2006-04-07 Stepan Kasal <kasal@ucw.cz>,

1847 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1848 distinguish m4sugar macros.
1849 * tests/tools.at (autoupdating with aclocal and m4_include):
1850 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1851 test case by Noah Misch <noah@cs.caltech.edu>.
1853 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1855 Revert my change from 2006-03-17, in other words:
1856 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1857 and DUALCASE=1.
1858 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1859 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1860 it is set.
1862 2006-04-07 Eric Blake <ebb9@byu.net>
1864 * doc/autoconf.texi (Programming in M4sh): Document that
1865 AS_MKDIR_P exits the script on failure.
1866 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1868 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1870 * config/elisp-comp, config/install-sh, config/mdate-sh,
1871 config/missing, config/mkinstalldirs: Sync from Automake.

1887 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1889 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1890 whether `set' quotes correctly: redirect stderr of the tested
1891 `set', and use a subshell, for Ultrix; use `sed' instead of
1892 `grep' for zsh `set' which may write binary output; match only
1893 at the beginning of a line, to avoid false positives.
1894 In order to avoid false positives by unrelated variables with
1895 multiline content, put the dump algorithm in a subshell and
1896 unset all variables containing newlines (except some which are
1897 special to the shell). Warn about cache variables that are
1898 unset.
1900 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1911 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1912 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1913 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1914 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1916 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1917 shell issue with double-quoted command substitutions of native

1940 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1942 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1943 ac_config_<foo>s again, sometimes normalized, sometimes not.
1944 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1945 (AC_CONFIG_COMMANDS): Do not do so here.
1946 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1947 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1948 2005-07-25 rewrite. Noticed by Noah Misch.
1950 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1951 _AC_PRESERVE_HELP_ORDER, ...
1952 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1954 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1955 inside m4_expand_once; it is redundant.

1958 for --help from Cygnus `configure.'
1960 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

2000 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
2001 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
2002 normalizing it, consistent it with previous releases.

2013 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
2014 Use 'comm' rather than N instances of grep; this also fixes a bug
2015 whereby substrings were incorrectly matched, causing us to not
2016 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2017 (exclude_list): Exclude empty macros.

2029 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
2030 a subdirectory subject to Cygnus `configure'.
2031 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
2033 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
2034 report request when we have no AC_PACKAGE_BUGREPORT.

2101 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2102 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2103 ac_file to the name of the default output file and call
2104 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2105 initial `rm' of the candidate files...
2106 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2107 the same list in subsequent `rm' calls, and for the temporary
2108 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2109 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2110 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2111 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2112 no longer needed) by libtool. Make it a cache check.
2113 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2114 copied here by mistake.
2115 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2116 _AC_COMPILER_EXEEXT.
2117 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

2150 Autoconf version number despite a zero- or one-argument AC_INIT.
2152 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
2153 subordinate tools.
2154 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
2155 * doc/autoconf.texi (autoreconf Invocation): Document it.
2157 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

2169 the correct lines of the input file by subtracting..
2170 (_au__first_line): ..this new definition.

2173 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.

2178 m4sugar macros.
2179 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.

2183 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
2184 hairy details.
2185 The AC_LANG_SAVE issue was reported against Libtool by
2186 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
2187 Kristian Kvilekval <kris@cs.ucsb.edu>.
2189 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2191 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
2192 switch all of them on and of when necessary. Fixes the bug when
2193 m4sugar macros (e.g., m4_define) were expanded after the first
2194 automatic update (e.g., after AC_PREREQ or AC_INIT).
2196 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

2221 aclocal cannot be given on the command line.
2223 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
2225 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
2226 Give an example for AS_DIRNAME instead of referring to Posix..
2227 (File System Conventions): Put discussion of // versus / here, and
2228 modernize it a bit.
2229 (Limitations of Usual Tools): Add basename. Remove verbiage
2230 after dirname, since it got moved to the above sections.
2231 All this was inspired by a patch proposed earlier by Eric Blake.
2233 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2235 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Quote

2239 `$0', $as_me.
2241 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2243 * bin/autoscan.in: The value of find_configure_ac should be
2244 checked for existence, so we don't barf over a nonexisting
2245 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
2247 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2249 * bin/autoupdate.in: Fix some typos.
2251 2006-03-21 Stepan Kasal <kasal@ucw.cz>

2835 `AC_SUBST($1)' in the public version.
2836 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
2837 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

2890 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2891 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2892 by the function rather than ignoring it.
2893 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2894 comparing its address. Intel's interprocedural optimization was
2895 outsmarting the old heuristic. Problem reported by
2896 Mikulas Patocka.
2898 2005-10-19 Stepan Kasal <kasal@ucw.cz>
2900 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

2907 2005-10-04 Stepan Kasal <kasal@ucw.cz>
2909 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
2910 before removing it (chmod -R u+rwx); there are three instances of this.
2912 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2913 Stepan Kasal <kasal@ucw.cz>
2915 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2916 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2917 make its content writable before removing it. Remove an errorneous
2918 comment from the end, where the logs of the failed tests are copied
2919 to the main log file.
2921 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2923 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
2924 in case the computer is too quick. Double quote the configure.ac
2925 snippets.
2927 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
2928 problems if the testsuite were running too fast.
2930 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2932 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2933 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2934 (which belong to Xt, not X itself). See Debian bug 327655.
2935 * NEWS: Mention this.
2937 2005-09-07 Stepan Kasal <kasal@ucw.cz>
2939 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
2941 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
2943 * config/move-if-change: Don't output "$2 is unchanged";
2944 suggested by Ben Elliston. Handle weird characters correctly.
2946 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2948 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2949 calls, so that the final expansion of this macro is shorter.
2950 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2951 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2952 the cleanup there. Use AS_VAR_* macros, to be more general.
2953 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2955 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2957 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2959 2005-09-01 Stepan Kasal <kasal@ucw.cz>
2961 * doc/autoconf.texi (Configuration Headers): Add an index entry
2962 for AH_HEADER.
2964 2005-08-26 Pavel Roskin <proski@gnu.org>
2966 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
2967 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
2968 running xmkmf.
2970 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2972 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2973 The previous patch didn't work, so try a better one.
2975 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2977 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2978 in the example. Reported by Bruno Haible.
2979 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2980 "if $undefined_var;" succeeds with my shell.
2982 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2983 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2984 but change the m4_divert_text to m4_divert_once.
2986 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2988 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2989 Work around bug in Solaris /usr/xpg4/bin/awk.
2990 The bug is present in at least Solaris 8 through 10.
2992 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2994 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2995 some evil values and relying on the fact that $* concatenates the
2996 parameters by the first character from IFS.
2998 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2999 Stepan Kasal <kasal@ucw.cz>
3001 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3002 first header appears, define AH_HEADER.
3003 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3004 Update limitations about when to call AC_CONFIG_HEADERS.
3005 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3006 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3007 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3008 ``Configuration Actions''; fix their index entries.
3010 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3011 options correctly. Process N-M as M-N if M is smaller than N.
3012 Process ranges correctly so that N-N will run only N.
3013 Sort and uniquify the tests that will be run. If there is more
3014 than one test, reinsert the banners for the tests.
3015 * tests/autotest.at (Keywords): Unmark XFAIL.
3017 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3019 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3020 before passing the macro name to AH_TEMPLATE.
3022 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3023 now opens log after option processing; in particular, --version
3024 and --help do not touch config.log.
3026 * Makefile.maint: Revert the change from 2005-08-12.
3028 2005-08-22 Stepan Kasal <kasal@ucw.cz>

3036 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3037 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3038 Language cleanup.
3040 * doc/autoconf.texi (Defining Symbols, Changed Results):
3041 Prepend to LIBS, not append, in examples.
3043 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3045 When building in place, set srcdir="."; suggested by Tim Van Holder.
3047 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3048 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3049 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3050 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3051 does not mean "no --srcdir option".
3053 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3055 * tests/autoscan.at (autoscan): New file.
3056 * tests/suite.at: Use it.
3057 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3058 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3060 * tests/autotest.at (Keywords): Test keywords combinations.
3062 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3064 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3065 add "2>&1"; gzip 1.2.4 prints help on stderr.
3067 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3069 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3070 was pushdef'ed twice while popped only once. Push it only once.
3071 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3073 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3075 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

3080 * Makefile.maint: Update from Bison.
3082 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3083 "<tab>" in comment, so that the point is understandable.
3085 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3087 Rewrite substantial part of lib/autoconf/status.m4.
3088 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3089 and CONFIG_COMMANDS are not processed in four separate loops.
3090 Instead, there is one main loop. This alows that the common code
3091 is expanded only once, thus config.status (and configure) is smaller.
3093 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3094 the AC_LIST_FILES and cousins macros are no longer used.
3096 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3097 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3098 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3099 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3100 contain the initialization, nor the for loop, nor the associated
3101 commands; all these go to ...
3102 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3103 _AC_OUTPUT_CONFIG_STATUS.
3104 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3105 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3106 (_AC_OUTPUT_FILE): The creation of the sed script ...
3107 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3108 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3109 _AC_OUTPUT_MAIN_LOOP.
3110 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3111 _AC_CONFIG_COMMANDS): Use ...
3112 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3113 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3114 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3115 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3116 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3117 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3118 ... new macros.
3119 (_AC_CONFIG_UNIQUE): Update.
3120 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3121 Replaced by this ...
3122 (_AC_LIST_TAGS): ... new common macro.
3123 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3124 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3125 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3126 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3127 this didn't belong to the `config commands' section.
3128 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3129 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3130 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3131 to the `config commands' section either.
3132 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3133 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3135 ... and many changes to the comments nearby.
3137 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3138 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3139 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3140 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3141 (#define header templates): The comment at the top of the generated
3142 header now includes the name(s) of the source file(s).
3144 Several unrelated small changes:
3146 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3147 parameter to AC_DIAGNOSE.
3148 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3149 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3150 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3151 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3152 with AU::AC_OUTPUT.
3153 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3154 in AC_OUTPUT doesn't double-quote it either.
3155 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3156 parameters.
3158 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3160 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3161 versions of Portland Group compiler produce single- and double-quoted
3162 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3163 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3165 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3167 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3168 This is a corrected version of yesterday's patch.
3170 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3172 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3173 path, too; insert a "===" to emphasize the line.

3177 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3179 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3180 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3181 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3182 (AC_ARG_VAR): ... here.
3183 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3184 target_alias.
3186 Keep a list of all precious variables and process them with one simple
3187 for loop, instead of expanding all commands, or, OTOH, complicated
3188 processing of output of "set".
3189 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3190 variable names in new macro...
3191 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.

3193 a loop to assign all ac_env_* and ac_cv_env_* variables.
3194 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3195 to INIT_PREPARE.
3196 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3197 its value to shell variable ac_precious_vars and call
3198 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.

3221 They are generated by the Tru64 v5.1B shell.
3223 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3225 Fix my changes from 2005-07-01; reported by Noah Misch.

3236 versions of autoconf.
3238 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3240 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3241 Problem reported by Patrick Welche.
3243 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3245 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3246 sed substitution command, so that we allow | in program prefixes
3247 and program suffixes. (& is a problem anyway; we're not fixing

3249 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3250 configure_input, top_builddir, srcdir, etc.
3251 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3252 PATH_SEPARATOR in AUTOTEST_PATH.
3254 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
3256 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the

3262 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

3288 for --help in that case.
3290 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3291 matches the order of execution. No code changed.

3313 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3314 (AC_SUBST): Call it.
3315 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3316 the directory specific variables; but don't call it for configure_input.
3318 2005-06-28 Derek Price <derek@ximbiot.com>
3320 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3321 addition.
3323 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3325 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3326 directory have inherent problems with special characters like spaces,
3327 due to limitations in Make syntax. Problem reported by Alexandre
3328 Duret-Lutz.
3329 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

3344 variable into diagnostic. Make the diagnostic an error, not a warning,
3345 because we really don't support spaces and suchlike in dir names.
3346 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3347 Don't worry about backslashes in srcdir; it can't happen now.

3374 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3375 b, t, r, w commands require single space, while : cannot have any.
3376 (Special Shell Variables): Fix sed code this in the example.
3377 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3378 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3380 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3381 expand to the empty list. Don't use two pairs of m4_changequote,
3382 it's not necessary.

3390 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3391 * doc/autoconf.texi:
3392 Don't mention Solaris versions so much, if a
3393 problem is common to all extant versions of Solaris. Say "SunOS
3394 4" instead of "SunOS" for SunOS 4.
3395 (awk): Mention more of the limitations of traditional Awk.
3396 (cat): Don't talk about cat -v.
3398 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

3403 to be compatible with glibc strverscmp.
3404 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
3406 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3407 on Mac OS X 10.4 reported by Peter O'Gorman in:

3412 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3414 * doc/autoconf.texi: "filesystem" -> "file system".
3415 "behaviour" -> "behavior".

3418 as per POSIX.
3419 * lib/m4sugar/m4sh.m4: Likewise.

3423 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
3424 (.x.1): Ignore the time stamp in the .TH line when deciding whether

3428 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
3429 quotes and backslashes. Patch from Derek Price.

3434 AS_TR_SH.
3436 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
3438 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3439 -u, since it outputs chatter if the input files are the same.
3440 Problem reported by Ralf Menzel.
3442 2005-06-08 Derek Price <derek@ximbiot.com>
3444 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3445 renaming them since they are about to be redefined anyhow.
3447 2005-06-08 Derek Price <derek@ximbiot.com>
3449 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3450 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3451 Move m4_undefine to alphabetical order.
3453 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3455 * README: Recommend GNU M4 1.4.3 or later.
3456 * doc/autoconf.texi (Introduction): Likewise.
3457 Reword to avoid some formatting glitches.
3458 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3459 Clarify explanation of HP compiler bug.
3460 Redo example output tp match current CVS snapshot.
3461 Use @example.org in email addresses when the examples
3462 might get inadvertently cut-and-pasted into user code.
3463 Remove example of autom4te usage that doesn't seem to work now.
3464 Use modern AC_INIT (except when the example is meant to be
3465 shown with Autoconf 2.13).
3466 Update ksh info for Solaris 9 and later.
3467 KB -> kB.
3468 Modernize description of Automake versions a bit.
3469 Don't claim a future version of Autoconf is near.

3476 Reword to avoid some formatting glitches.
3477 * doc/installt.exi: Reword to avoid some formatting glitches.
3479 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3480 Tru64 ksh pattern matching bug. Reported against Libtool by
3481 Albert Chin <libtool@mlists.thewrittenword.com> and
3482 Nicolas Joly <njoly@pasteur.fr>.
3484 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3486 m4_cdr of one-member list was [[]] (one-member list containing an
3487 empty string) instead of [] (an empty list. Callers were skewed to
3488 match this misbehaviour. As a consequence of this:
3489 - m4_foreach([x], [], [foo]) expanded to `foo', while
3490 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3491 This bug has been fixed:
3493 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3494 expand to an empty string; print error msg if called without
3495 an argument list.
3496 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3497 misbehaviour; handle [] and [[]] correctly.

3505 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3507 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3508 swallow records with more than 99 fields.
3509 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3510 parse the long line.
3512 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3514 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3515 swallow literals longer than 399. Reported by Ralf Wildenhues.

3521 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3522 to gfortran, and make these the first two compiler names
3523 checked (following the general autoconf preference for gcc).
3525 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3527 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3528 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3529 (testsuite): Make sure autotest.m4f is up-to-date before using it.

3533 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3534 expression of unbounded size when processing the --list
3535 option. This runs afoul of a limit of 399 bytes per regular
3536 expression on AIX. Problem reported by Ralf Wildenhues.

3545 Reword description of line replacement.
3547 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3549 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3550 now contain newlines, and substituted files must be referenced on
3551 a line alone; the sed scripts to substitute them are now very
3552 different.
3553 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3554 commands can be put in a sed script portably.
3555 * doc/autoconf.texi (Setting Output Variables): Document above

3568 classes in shell scripts. The test was too brittle.
3570 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3572 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3573 * doc/autoconf.texi (Limitations of Builtins): Document this
3574 limitation.
3576 2005-05-24 Stepan Kasal <kasal@ucw.cz>

3586 messages when ac_unique_file is not found.
3587 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3588 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo

3603 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3604 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3605 (ac_top_builddir): ... this ...
3606 (ac_top_build_prefix): ... to this; the old name is also kept, for
3607 backward compatibility.
3608 (ac_top_builddir_sub): New variable, without the trailing slash,
3609 always nonempty.
3610 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

3624 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3625 argument to m4_foreach. I guess it was necessary in the past,
3626 but I think it's a no-op now.
3628 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3630 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3631 ``cat <<_ACEOF'' commands to one.
3632 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3633 * lib/autoconf/status.m4: On various places, use expr instead of
3634 ``echo|sed.''
3635 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3636 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3637 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3638 a range.
3639 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3640 the wrong patterns between ``case'' and ``esac.'' The previous
3641 code had false positives.
3643 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3645 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3646 as on 2005-05-02.
3647 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3648 Mention LIBOBJDIR.

3688 2005-05-13 Stepan Kasal <kasal@ucw.cz>
3690 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
3691 check.
3692 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3693 enough arguments, similarly as in m4_bpatsubsts.
3695 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3697 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
3698 of absolute paths.
3700 2005-05-11 Stepan Kasal <kasal@ucw.cz>
3702 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3703 for absolute directory names in one loop.
3704 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3705 abbreviations of --version and --debug.
3707 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3709 * doc/autoconf.texi (Autoconf Language): Be more precise about
3710 quoting rules. Problems noted by Stepan Kasal.
3711 Also, throughout this document, be more careful about white space.
3712 "blank", "white space", and "space" all have different meanings
3713 and we should be careful to say what we mean.
3715 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3717 Fix C++ related problems reported by Werner Lemberg.
3718 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3719 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3720 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3721 avoid problems with C++ and throw.
3722 * tests/compile.at: .cpp, not .cc.
3724 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3726 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3728 * doc/autoconf.texi (Generic Functions): Typos.
3730 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3732 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3733 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3734 set by latest automake.
3736 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3738 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3739 outputs 0 on GNU/Linux these days.
3741 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3743 * doc/autoconf.texi (Autoconf Language): Add more description
3744 about quoting heuristics.
3745 (Limitations of Builtins): Describe "set -" problems.
3747 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3749 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3750 not newline.
3752 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3753 by AC_DEFINE; it was a mistake.
3754 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3756 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3758 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3760 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3762 * doc/autoconf.texi (External Software): Quadrigraphs are not
3763 processed correctly in AS_HELP_STRING; avoid this in the examples.
3764 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3765 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3766 comment and reduce m4_default([foo], []) to [foo].
3767 (m4_strip): Update the explanation.
3769 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3771 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3772 Remove core.conftest.* too; it's generated by Tru64 5.1.
3773 Problem reported by Jennis Pruett.
3774 * lib/autoconf/functions.m4
3775 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3776 Don't bother to remove core files; AC_RUN_IFELSE should do that
3777 for you.
3779 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3781 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
3783 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

3788 2005-04-15 Stepan Kasal <kasal@ucw.cz>
3790 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
3791 the comment.
3793 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3795 * doc/autoconf.texi (External Software, Package Options): Add
3796 examples showing how to implement --with-* and --enable-* options.
3798 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3800 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3801 as well as configure.in. Problem reported by Gregorio Guidi.
3803 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3805 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3806 pattern for alloca snippet.
3808 2005-04-04 Stepan Kasal <kasal@ucw.cz>
3810 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
3812 2005-04-01 Stepan Kasal <kasal@ucw.cz>
3814 * doc/autoconf.texi (Generic Programs): Fix a typo.
3816 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3818 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3819 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3821 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3823 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3824 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3825 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3826 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3827 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3829 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3831 * NEWS: The configure command now warns you if you attempt to use
3832 a directory whose name contains a special character like space,
3833 newline, or "\".
3834 * doc/autoconf.texi (Installation Directory Variables): Allow
3835 "," in file names. Do not use \@; it's not a portable regexp.
3836 * bin/Makefile.am (edit): Likewise.
3837 * lib/Makefile.am (edit): Likewise.
3838 * tests/Makefile.am (edit): Likewise.
3839 * tests/semantics.at: Likewise.
3840 * tests/torture.at: Likewise.
3841 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3842 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3843 * doc/autoconf.texi (File System Conventions): Warn about
3844 unportable file names.
3845 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3846 (AC_INIT): Use it.
3847 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3848 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3849 ac_pwd, and quote srcdir.
3850 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3852 * doc/autoconf.texi: Fix some systematic formatting problems.
3853 ".)" needs a following @: if not at the end of a sentence, and
3854 similarly for "!)". "etc." should be preceded by a comma.
3855 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3857 2005-03-22 Bruno Haible <bruno@clisp.org>
3859 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3860 argument is often called 'build-aux'.
3862 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3864 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3865 macro AC_TRY_LINK is obsolete.
3866 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3867 `AC_CONFIG_FILES'.
3869 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3871 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3872 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3873 from a Common Lisp's `cl'.
3874 (AC_PROG_CXX): Behave according to the documentation: don't
3875 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3876 make the variable CCC precious; use `cl.exe', not `cl'.
3878 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3879 Alexandre Duret-Lutz <adl@gnu.org>
3881 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3882 /dev/null, as "configure" shouldn't read stdin, and this insulates
3883 us from problems (e.g., when testing for "cl"). Also, do this
3884 redirection before invoking "hostname" or "uname", and keep the
3885 original input stream available via...
3886 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3887 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3888 bother with "</dev/null" since it's now done at the top of
3889 'configure'.
3890 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3891 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3892 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3893 * doc/autoconf.texi (File Descriptor Macros): New section.
3894 (Printing Messages): Mention it.
3895 * tests/base.at (Input/Output): New test.
3897 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3899 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3900 newline if neither \c nor -n work, as that would output two
3901 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3903 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3905 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3906 This causes that any required macros inside will get before the if.
3907 * doc/autoconf.texi (autom4te.cache): A typo.
3909 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3911 Undo previous change, except keep the change to
3912 lib/autoconf/programs.m4 that replaced grep with shell
3913 pattern-matching. This is because net-snmp configure reads stdin.
3914 Reported by Noah Misch.
3916 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3918 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3919 from /dev/null, as "configure" shouldn't read stdin, and this
3920 insulates us from problems (e.g., when testing for "cl").
3921 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3922 before invoking "hostname" or "uname".
3923 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3924 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3925 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3926 "</dev/null" since it's now done at the top of 'configure'.
3927 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3928 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3929 Also, replace grep with shell pattern-matching, to save a process.
3931 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3933 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3934 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3935 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3936 compiler.
3938 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3940 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3941 grep -q isn't portable. Improve grep -s explanation.
3942 Problem reported by Dan Manthey.
3944 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3946 * doc/autoconf.texi (Special Shell Variables): Clarify
3947 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3949 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3951 * doc/autoconf.texi: Use @acronym for DJGPP.
3952 Fix some @code's that should have been @env's, and vice versa.
3953 Sort environment variable names.
3954 Mention that shells no longer inherit IFS.
3955 Don't recommend PATH_SEPARATOR=';' so strongly.
3956 Mention that $RANDOM might expand to the empty string.
3957 "symlink" and "soft link" -> "symbolic link".
3958 Improve mktemp description (reported by Bruno Haible).
3960 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3962 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3963 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3964 Likewise.
3965 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3966 Likewise.
3968 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3970 * NEWS: Mention AT_COPYRIGHT.
3972 * tests/local.at (AT_CMP): Use diff directly on input files rather
3973 than copying them.
3975 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3976 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3978 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3979 and Paul Eggert <eggert@cs.ucla.edu>
3981 * tests/autotest.at (Empty test suite): New test.
3982 * tests/torture.at (Substitute and define special characters)
3983 (Substitute a 2000-byte string, Define to a 2000-byte string)
3984 (Substitute a newline, Define a newline): New tests.
3986 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3988 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3989 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3990 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3991 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3992 (Standard regular expressions): New test.
3993 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3994 excess test name quoting.
3995 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3996 CPPFLAGS to `configure' instead of setting it in `configure'.
3998 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3999 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4000 on some platforms.
4002 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4003 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
4005 * tests/local.at (AT_CMP): New macro.
4006 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
4007 (AC_SAVE_STATE): Move environment grep...
4008 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
4009 (AT_CONFIG_CMP): New macro.
4010 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
4011 * tests/c.at (Extensions): Do not exit early.
4012 * tests/atlocal.in: Inherit $GREP.
4014 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
4015 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
4017 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
4018 (AC_COPYRIGHT): Factor header comment portion out and move into...
4019 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
4020 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
4021 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
4022 --version output.
4023 * tests/local.at: Add Autoconf test suite copyright notice.
4024 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
4026 2005-02-04 Bruno Haible <bruno@clisp.org>
4027 and Paul Eggert <eggert@cs.ucla.edu>
4029 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
4031 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4033 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4034 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4036 Try not to generated lines of unlimited length, as POSIX places a
4037 2047-byte limit on line length of portable text files.
4038 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4039 Use newline as a separator, not space.
4040 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4041 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4042 space.
4044 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4046 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4047 as_func_*. Add test to check whether positional parameters
4048 are restored after function return.
4050 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4052 * doc/autoconf.texi (Special Shell Variables): Mention _,
4053 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4054 if they contain a lower-case letter. The DUALCASE problem was
4055 reported by Ralf Wildenhues.
4057 * bin/autoconf.as: Don't exit with status 0 after write failure
4058 with --help or --version.
4059 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
4060 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

4072 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4073 care to echo the commands, so the user knows what's going on.
4074 Modified from a suggestion by Stepan Kasal.
4076 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
4077 with a cross reference. Derived from a suggestion by Bruce Korb.

4097 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4098 Update the long comment explaining it.
4100 m4_require no longer writes an ``is required by'' line to the
4101 execution stack. It contains only one bit of non-redundant
4102 information: that the macro was required, not called. And even
4103 this bit is useless in most situations: have you ever met a macro
4104 which both calls and requires the same macro?
4106 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4107 (_m4_defun_pro_outer): ... only via this macro, for the outermost

4110 (m4_expansion_stack_pop): Remove the misplaced comment.

4114 (_m4_require_call): Use it.
4115 * tests/m4sugar.at (m4_require): Expect output without the
4116 ``is required by'' messages.
4118 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4120 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4121 rather than x for expr.
4123 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4124 this is safe.
4125 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4126 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

4139 support.
4140 * bin/autoheader.in: Pass $force to update_file so that
4141 config.h.in is always recreated when --force.

4145 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4147 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4149 * doc/autoconf.texi (Limitations of Builtins): Clarify that

4152 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4154 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4155 Warn about newline stripping in `` and $(). Update Solaris
4156 version to 9.
4157 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4158 X insulates us from future changes to Posix.
4159 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4160 stripping.
4162 2005-01-19 Stepan Kasal <kasal@ucw.cz>

4182 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
4184 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4186 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

4208 (_m4_divert_n_stack): New macro; the expansion is
4209 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4210 otherwise.
4211 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4212 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4213 stored in _m4_divert_diversion or _m4_divert_dump.
4214 (m4_divert_pop): When the parameter is given, compare the symbolic
4215 name with the last diversion pushed on the stack. Previously, the
4216 current diversion was compared with the numeric value of the
4217 diversion given as the parameter.
4218 (m4_require): If the macro hasn't been expanded yet, call ...
4219 (_m4_require_call): this new macro.

4252 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
4253 signals that the package uses Automake; a `Makefile.am' is typical but
4254 not essential. Reported by Magnus Therning.
4255 * tests/torture.at (autoreconf.): New banner.
4256 (autoreconf and non-AC configure): Rename to `Non-Autoconf
4257 AC_CONFIG_SUBDIRS'.

4305 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
4306 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

4433 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

4501 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
4502 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

4520 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
4521 value of the #define--default to 1, iff the macro was called
4522 with exactly one parameter.
4524 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4526 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4527 "char c = '\200';" rather than "char c = 0x80;" as the
4528 latter doesn't conform to the strict C standard due to
4529 overflow on signed char hosts.
4531 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4532 to -qlanglvl=ansi. We don't want to disable extensions.
4534 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
4536 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
4537 (Using Autotest, testsuite Scripts, Writing testsuite.at):
4538 Reword slightly to avoid some English-language problems noted

4588 simplify the examples and improve their quoting.
4590 2004-11-13 Stepan Kasal <kasal@ucw.cz>
4592 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
4593 the $1_found variable, don't test whether the file is executable;
4594 Both things are checked ...
4595 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
4596 the former ``test -f''.
4597 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
4599 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

4602 use cp -R instead.
4604 2004-11-10 Derek R. Price <derek@ximbiot.com>
4606 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
4607 limitations. Reorder paragraphs for clarity.
4609 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
4611 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
4612 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
4613 variants", "Unix", and some related minor wording fixups.
4615 (Shellology, Special Shell Variables): Document that the Zsh
4616 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

4628 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
4630 * doc/autoconf.texi (auindex): New macro.
4631 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
4632 Problem reported by Stepan Kasal.
4634 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
4636 Fix problems reported by Andreas Buening in:
4637 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
4638 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
4639 in test makefile.
4640 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
4641 readable; it's not true in OS/2-emx.
4643 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4645 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4646 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4647 (trivial change). Problem and patch reported by Andrew Church in:
4648 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4650 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
4652 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

4655 Also, fix some minor spacing and punctuation bugs.
4657 2004-09-02 Akim Demaille <akim@epita.fr>
4659 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
4660 "case" to restore ordering.
4661 Reported by Stepan Kasal.

4671 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
4673 Version 2.59b.
4675 * README: Add advice about m4 1.4.2.
4677 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4678 texinfo.tex for now (done by hand now).
4679 * Makefile.maint (wget_files, cvs_files):
4680 Remove ansi2knr.c; nobody uses it.
4681 (ansi2knr.c-url_prefix): Remove.
4682 (cvs-update): Fix test for failure. I don't know why it ever
4683 worked...
4685 * doc/autoconf.texi: Update URLs, some of which went stale.
4686 Use @uref rather than @href.
4688 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4689 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4691 * config/config.guess, config/config.sub, config/elisp-comp,
4692 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4693 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4695 * NEWS, TODO, configure.ac, bin/autoscan.in,
4696 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4697 doc/install.texi, lib/Autom4te/Configure_ac.pm,

4701 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4702 tests/tools.at, tests/torture.at:
4703 Use "file name" rather than "filename" or "path",
4704 to be consistent with the terminology of the GNU coding standards.
4706 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4708 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4709 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4710 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4711 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4713 More fixes to support spaces in the name of the build directory.
4714 This isn't a complete fix but it's an improvement.
4716 * bin/autoconf.as (autom4te_options): New var.
4717 Use it instead of appending to AUTOM4TE, so that we can allow
4718 spaces in the build directory's absolute name.
4719 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4720 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
4721 AT_CHECK_NOESCAPE): Likewise.
4722 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
4723 main program): Likewise.
4725 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
4727 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
4728 From Ralf Corsepius in:

4731 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4733 * doc/autoconf.texi (Function Portability): Document isinf and
4734 and isnan. From a suggestion by Kevin Ryde.
4736 * lib/Autom4te/General.pm (END): Return correct exit status even
4737 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4739 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4741 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4742 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4743 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4745 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4747 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4748 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4749 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4750 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4751 * lib/autom4te.in (Automake-preselections): Preselect
4752 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4754 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4756 * lib/autom4te.in (Automake-preselections): Preselect
4757 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4758 trace them.
4760 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4762 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4763 Tru64.
4764 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4765 Document problem with "`""`" in pdksh POSIX mode.
4767 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4769 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4770 with pdksh, too. Problem reported by Patrick Welche via
4771 Gary V. Vaughan.
4772 * doc/autoconf.texi (Shellology): Note that set -o posix is
4773 useful for pkdsh, too.
4775 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4777 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4778 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4779 Don't fail if ENV or BASH_ENV is readonly.
4780 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4781 etc. are read only. Problem reported by Ludovic Courtes.
4783 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4785 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4786 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4787 (trivial change)
4789 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4791 * doc/autoconf.texi (File System Conventions): Warn about
4792 names like "aux". Problem reported by Eric Blake.
4794 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4795 by zero instead of array size, so that we can use any arithmetic
4796 constant expression (instead of requiring an integer constant
4797 expression). This allows us to test expressions like DBL_MAX <
4798 LDBL_MAX, which didn't conform to the C standard using the old
4799 method.
4800 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4801 now that we can do floating-point tests at compile time.
4803 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4805 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4806 and LDBL_EPSILON, as the resulting expression isn't an
4807 integer constant expression and violates the C standard.
4808 Problem reported by Nelson H. F. Beebe. Also, check
4809 for "L" suffix, and check that long double doesn't have
4810 worse range or precision than double, that mixed-mode
4811 arithmetic doesn't generate a diagnostic, that double
4812 constants fit in long double.
4814 2004-06-03 Kevin Ryde <user42@zip.com.au>
4816 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4817 malloc(0) and realloc(NULL,size).
4819 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4820 Bob Proulx.
4822 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4824 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4825 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4826 by Jim Meyering.
4828 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4830 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4831 can be rewritten using if-then-else. Suggested by Bruno Haible.
4833 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4835 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4836 Problem reported by Stepan Kasal.
4838 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4840 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4841 change). Patch reported by Ralf Wildenhues in
4842 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4844 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4845 function F exists if the compiler and linker let you compile an
4846 expression like (F != 0). Recent versions of GCC optimize away
4847 the reference to F in that case, since every function address must
4848 be nonzero, so the link succeeds even if F does not exist.
4849 Problem reported by Manu in
4850 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4852 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4853 "Unix". Many uses changed.
4854 (Limitations of Builtins): Explain better why the ! command isn't
4855 portable.
4857 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4859 * lib/autom4te.in (Automake-preselections): Preselect
4860 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4862 2004-05-19 Kevin Ryde <user42@zip.com.au>
4864 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4865 referencing AC_FUNC_STRERROR_R.
4867 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4868 note pessimistic assumption when cross compiling.
4870 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4872 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4873 (until 2004) invoked subcommands with sh -e, contra POSIX.
4874 Reported by Kevin Ryde.
4876 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4878 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4879 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4880 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4881 `test -f " /usr/bin/grep"', which _always_ failed.
4882 (AC_PROG_SED): Ditto bogus PATH fix.
4883 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4884 requires that grep correctly supports _multiple_ `-e' options, rather
4885 than stating only that grep should accept `-e'.
4887 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4889 Port to C99, which requires that 'exit' be declared.
4891 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4892 to ensure that stdlib.h is included.
4893 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4894 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4895 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4896 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4897 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4898 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4899 when using 'exit' in a test; C99 requires that 'exit' be declared.
4901 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4903 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4904 now prefers 'grep' implementations that accept -e.
4905 (Limitations of Usual Tools): Describe problems of traditional
4906 egrep and fgrep with long input lines, and of traditional grep
4907 with -e.
4908 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4909 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4910 All callers changed. Append /usr/xpg4/bin to the PATH, for
4911 Solaris.
4912 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4913 the user with complaints about multiple -e options.
4914 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4915 Define it with AC_PROG_GREP.
4916 * configure.ac (AC_PROG_GREP): Add.
4917 * lib/freeze.mk (GREP): New macro.
4919 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4921 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4922 a possible candidate only after all others fail, rather than
4923 consulting it first. This improves backward compatibility by
4924 better reflecting the way shell selection occurred in previous
4925 versions of Autoconf, and should help to avoid triggering latent
4926 problems in other packages, such as the one in Automake where zsh
4927 is not handled robustly:
4928 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4929 Although it is not Autoconf's responsibility to work around
4930 problems in Automake, it nevertheless makes sense to avoid
4931 introducing unnecessary incompatibilites.
4933 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4934 Gary V. Vaughan <gary@gnu.org>
4936 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4937 how deeply nested we are when a suitable tool is found, set the
4938 ac_path_TOOL_found flag.
4939 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4940 nested we are in this macro. Break out of all 3 nested loops if
4941 ac_path_TOOL_found is set.
4943 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4945 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4946 of the _AS_PATH_WALK loop too if GNU flavor is found.
4948 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4950 * doc/autoconf.texi (Limitations of Make): Update documentation
4951 for `$<'. New entry `Long lines', based on a report from Simon
4952 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4953 paragraph about DJGPP, based on a mail from Richard Dawe.
4955 2004-04-20 Paul Eggert <eggert@twinsun.com>
4957 * tests/c.at (C keywords): Don't assume that GCC supports
4958 "restrict" and "inline", as sufficiently-old GCC versions do not
4959 (also, GCC configured to be in pedantic C89 mode does not).
4960 Problem reported by Sumit Pandya in:
4961 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4963 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4964 consider -g to work if it generates warnings when plain compiles
4965 don't. Problem reported by Braden McDaniel in:
4966 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4968 * doc/autoconf.texi (Slashes): New section, to document a problem
4969 reported by Jim Meyering in:
4970 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4972 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4973 linker output files before linking, to work around IRIX 6 linker bug.

4977 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4979 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4980 best tool so far counter rely on the tool path variable name to
4981 avoid checks for one tool being affected by the results of running
4982 the length check on a previous tool.
4984 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4985 match expression argument, as different greps have different
4986 regular expression flavours.
4987 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4988 literals.
4989 (AC_PROG_EGREP): Pass 'EGREP$'.
4990 (AC_PROG_GREP): Pass 'GREP$'.
4992 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>

5000 Types, Specific Compiler Characteristics, System Services,
5001 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5002 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5003 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5004 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

5017 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5018 now defines HAVE_DECL_TZNAME if it is declared, when
5019 HAVE_STRUCT_TM_TM_ZONE is not defined.
5020 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5021 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5022 for HAVE_TZNAME.
5024 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5026 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected

5034 H. F. Beebe for the bug report.
5036 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5038 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5039 quoted -cmdline argument in Portland Group compiler (bug
5040 reported by Jeffrey J. Barteet).
5042 2004-03-25 Kevin Ryde <user42@zip.com.au>
5044 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5045 (Run Time): ... here, where it's now mentioned.

5070 new macros.
5071 * NEWS: Document these changes.
5073 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5074 they make TeX hang up.

5079 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5080 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5081 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5082 vowel.

5102 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5104 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
5105 is not always thread-safe. Report from Nathanael Nerode.
5107 2004-02-18 Paul Eggert <eggert@twinsun.com>
5109 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5110 problem on QNX reported by Stephen Rasku in
5111 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5113 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5114 $(m4sh_m4f_dependencies); this removes a FIXME.
5115 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5116 (MAINTAINERCLEANFILES): Split into pieces,
5117 one per related section. Add $(srcdir)/wrapper.in.
5119 2004-02-09 Paul Eggert <eggert@twinsun.com>
5121 * doc/autoconf.texi (Setting Output Variables): Emphasize that
5122 AC_SUBST provides no portable way to escape literal newlines.
5124 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5125 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5126 Darwin uses -lcrt2.o and there's little point to cataloging all
5127 the system variants. Partial fix reported by Andreas Waechter in:
5128 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5129 for bug reported by Nelson H. F. Beebe in:

5144 the behavior of the third argument.
5145 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5146 correctly the behavior of the third argument. Document

5151 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5152 Eric Sunshine <sunshine@sunshineco.com>
5153 Paul Eggert <eggert@twinsun.com>
5155 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

5157 parameter. Expand _AS_SHELL_FN_SPY.
5158 (AS_INIT_WITH_SHELL_FN): Removed.
5159 (_AS_SHELL_FN_SPY): New macro.
5160 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5161 macros.
5162 (AS_SHELL_SANITIZE): Remove loop to find better shell
5163 and documentation for the parameter.

5167 (AS_REQUIRE_SHELL_FN): Require shell functions when
5168 it is used.
5169 (_AS_LINENO_WORKS): Put around braces, we do not
5170 trigger the bash bug anymore.
5171 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5172 use AS_INIT_WITH_SHELL_FN.
5173 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5175 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5177 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

5181 (AU_DEFUN): Honor the third parameter, create autoupdate
5182 macros with AU_DEFINE.
5183 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
5184 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

5203 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5204 2003 (except 1997) to the list of copyright years. This undoes
5205 the 2003-05-22 change, which removed the older years from the list.
5206 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5208 2004-01-27 Gary V. Vaughan <gary@gnu.org>
5209 Albert Chin-A-Young <china@thewrittenword.com>

5220 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5221 longest input length accepted by a command.
5222 (AC_PROG_SED): Use it.
5223 * doc/autoconf.texi (Particular Programs): Document the changes.
5224 * NEWS: Updated.
5226 2004-01-27 Paul Eggert <eggert@twinsun.com>

5248 sources.
5250 2004-01-26 Paul Eggert <eggert@twinsun.com>
5252 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5253 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5254 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5255 not <inttypes.h>. Problem reported by Tim Mooney in
5256 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5257 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5258 Likewise.
5260 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5261 otherwise "make check" fails because it forbids cmp (I guess
5262 because cmp treats files as binary on DOS-like systems).
5264 * tests/mktests.sh: Update copyright date to 2004, since some tests
5265 have changed in 2004.
5267 2004-01-23 Gary V. Vaughan <gary@gnu.org>
5269 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
5270 non-truncating sed or gsed program in PATH.
5271 * tests/acprograms.at: Add it.

5273 * NEWS: Updated.
5275 2004-01-15 Paul Eggert <eggert@twinsun.com>
5277 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5278 -std1 disables some useful extensions on Tru64. Problem reported
5279 by N. Lichtmaier in
5280 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5282 2004-01-14 Paul Eggert <eggert@twinsun.com>
5284 * doc/autoconf.texi (Programming in M4sh): Document that
5285 AS_MKDIR_P succeeds if the destination is a symbolic link
5286 to an existing directory.
5287 (Limitations of Usual Tools): Note that mkdir -p might not
5288 succeed on symlinks to directories.
5290 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5292 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
5293 * bin/autoheader.in: Grammar fix in message.
5294 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
5295 Test for dir before calling mkdir -p. (trivial changes)
5297 2004-01-13 Eric Blake <ebb9@byu.net>
5299 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5300 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5302 2004-01-10 Jim Meyering <jim@meyering.net>
5304 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
5306 2004-01-09 Paul Eggert <eggert@twinsun.com>
5308 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5309 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5310 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5311 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5312 AC_COMPILE_IFELSE, since we now assume our caller invokes
5313 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5314 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5315 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5316 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5318 2004-01-07 Paul Eggert <eggert@twinsun.com>
5320 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5321 `"'...'"`, as it's confusing (and I suspect it may not work on
5322 some platforms). The code was incorrect anyway, as it assumed
5323 that \$ evaluated to itself in that context. Reported by
5324 Alexandre Duret-Lutz.
5326 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
5328 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
5329 and _LT_AC_TAGCONFIG.
5331 2004-01-06 Paul Eggert <eggert@twinsun.com>
5333 * doc/autoconf.texi (One Macro Call): Fix an incorrect
5334 example, and add more examples. Reported by Eric Sunshine.
5336 2004-01-05 Paul Eggert <eggert@twinsun.com>
5338 * doc/autoconf.texi (Limitations of Usual Tools):
5339 Remove warning against "rm -fr" introduced yesterday; it
5340 was a false alarm.
5342 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
5343 autoscan, autoupdate, ifnames): Don't use chmod -w.
5344 * lib/Makefile.am (autom4te.cfg): Likewise.
5345 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
5346 "chmod -w".

5349 Paolo Bonzini <bonzini@gnu.org>
5351 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
5352 by doing lineno substitution only on lines containing "$LINENO".
5354 2004-01-04 Paul Eggert <eggert@twinsun.com>
5356 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
5357 Use "rm -f" to remove conftest.sed, not plain "rm".
5358 Bug reported by David Relson in
5359 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
5361 * Makefile.am (autom4te-update):
5362 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
5363 * Makefile.maint (my-distcheck, do-po-update): Likewise.
5364 * doc/autoconf.texi (Guidelines): Likewise.

5372 srcdir): Likewise.
5373 * doc/autoconf.texi (Limitations of Usual Tools):
5374 Warn against "rm -fr".
5376 2004-01-03 Paul Eggert <eggert@twinsun.com>
5378 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5379 -c -o might not work. From a suggestion by Kevin Ryde.
5380 (C Compiler, Generating Sources, Limitations
5381 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5382 Don't put '-o' after non-options, as POSIX doesn't allow this.
5383 Mention that cc's name might be gcc or c89 or whatever.
5385 2004-01-04 Kevin Ryde <user42@zip.com.au>
5387 * doc/autoconf.texi: Add various further index entries.
5389 2003-12-29 Paul Eggert <eggert@twinsun.com>
5391 * bin/autoreconf.in (autoreconf_current_directory):
5392 Fix typo: mkdir without umask arg.
5394 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
5396 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
5397 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
5398 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
5399 explanation clearer.
5401 2003-12-24 Andreas Schwab <schwab@suse.de>
5403 * doc/autoconf.texi (Default Includes): Fix misspelling of
5404 AC_INCLUDES_DEFAULT.

5408 * configure.ac: Test if sh -n works.
5409 * configure: Regenerate.

5450 * config/announce-gen (&print_locations, &print_signatures)
5451 (&sizes): New.
5452 Use them.
5453 No longer rely on Gnus to inline the list of signatures: compute
5454 them on the fly.
5456 2003-11-24 Akim Demaille <akim@epita.fr>
5458 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
5459 override some files.
5460 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
5461 From Debian Autoconf 2.58.
5463 2003-11-24 Akim Demaille <akim@epita.fr>

5501 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
5502 than $target since the latter is not usual, add guidelines on when to

5507 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

5527 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

5662 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5663 cross test.
5665 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5667 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5668 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

5680 Problems reported by Eric Sunshine.
5682 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5684 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5685 -mGLOB_options_string stuff for Intel ifc, which can cause
5686 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

5691 * doc/autoconf.texi: Document new FC Fortran macros.

5709 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5710 cache variable instead of $G77 to decide whether to include -O2,
5711 since $G77 is specific to Fortran 77.

5715 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

5718 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5720 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5721 arguments so that it can be used with syntax identical to
5722 AC_PROG_F77, and so that we can more easily decide to
5723 remove/deprecate the DIALECT optional argument in the future if it
5724 proves troublesome.
5725 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5726 non-freeform-supporting compilers. Document freeform flags.
5728 2003-10-03 Akim Demaille <akim@epita.fr>
5730 * configure.ac: Look for emacs, not macs.
5731 Reported by Eric Sunshine.
5733 2003-10-03 Akim Demaille <akim@epita.fr>
5735 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5736 * bin/autoreconf.in (autoreconf_current_directory): Create the
5737 AUX_DIR if needed, for sake of automake --add-missing etc.
5738 Suggested by Alexandre Duret-Lutz.
5740 2003-10-03 Akim Demaille <akim@epita.fr>
5742 * configure.ac: Quotation and formatting changes.

5764 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
5765 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

5772 (@news_file): this.
5774 2003-09-30 Nicolas Joly <njoly@pasteur.fr>

5777 have been created when invoking the compiler.

5791 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5792 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5793 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5795 2003-09-26 Akim Demaille <akim@epita.fr>
5797 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5798 directory for AC_CONFIG_COMMANDS' first argument exists.
5799 This makes valid the invocation of _AC_SRCPATH that follows.
5800 Reported by Eric Sunshine.
5801 * doc/autoconf.texi (Configuration Commands): Adjust.
5803 2003-09-26 Akim Demaille <akim@epita.fr>
5805 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5806 Reported by Ralf Corsepius.

5810 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5811 arguments.

5822 2003-09-26 Akim Demaille <akim@epita.fr>
5824 The test suite are sometimes assigning timings incorrectly.
5825 Reported by Henk Krus.
5826 Diagnosed by Nicolas Joly.
5828 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5829 AT_help_all.
5830 Instead of making AT_help a sequence of assignments to grow
5831 $at_help_all, just make AT_help_all be the growing contents of
5832 $at_help_all, and make a single assignment in...
5833 (AT_INIT): here.
5834 (at_times_skip): Flip the meaning and rename as...
5835 (at_times_p): this.
5836 (AT_INIT): When summarizing the test that ran, remove
5837 $at_times_file after use, and check it is present before trying to
5838 use it.

5846 (ifnames): chmod -w.
5847 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5848 executables, not bin/ executables! Otherwise all the magic needed
5849 to find non installed files is turned off. This caused a failure
5850 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5851 as found in its environment (sent by tests/autoreconf): pointing
5852 to bin/autom4te that could not find its files.
5853 * tests/mktests.sh: Force the replacement of generated files, for
5854 the sake of "mv" program that are interactive when overwriting a
5855 -w file.

5866 Trivial change to support GCC's configuration procedure.
5867 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5868 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5869 about inconsistency if the preprocessor is set to give errors for
5870 any warning.
5871 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5873 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

5889 2003-09-12 Akim Demaille <akim@epita.fr>
5891 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5892 not asm/types.h.
5894 2003-09-11 Akim Demaille <akim@epita.fr>
5896 * doc/autoconf.texi (Header Portability): linux/random.h.
5897 From Peter Hendrickson.
5899 2003-09-10 Akim Demaille <akim@epita.fr>
5901 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5902 willing to edit the output files.

5926 From a suggestion by Ian Lance Taylor in
5927 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5929 2003-09-05 Paul Eggert <eggert@twinsun.com>
5931 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5932 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5934 2003-09-04 Akim Demaille <akim@epita.fr>
5936 * tests/mktests.sh (ac_exclude_list): Fix the filtering of

5951 Add support for newer Fortran dialects. The F77 interface is
5952 unchanged, and continues to support Fortran 77. New FC macros
5953 correspond to all the old F77 macros, with output variables FC,
5954 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5955 available dialect, but older dialects can be specified. There are
5956 new macros AC_FC_SRCEXT to set the source extension, and
5957 AC_FC_FREEFORM to accept free-form source files.

5988 'touch -r' have.
5990 2003-08-27 Akim Demaille <akim@epita.fr>
5992 * tests/m4sugar.at (cross_warning): Make sure to enable the
5993 output, so that we can track spurious m4sugar output.

5995 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5996 are defaulted by AT_CHECK anyway.
5997 Use AT_CHECK_AUTOM4TE.
5998 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5999 missing dnl.
6001 2003-08-27 Akim Demaille <akim@epita.fr>
6003 * bin/autoheader.in: Issue the "Using auxiliary..." message only

6067 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6068 (&verbose): Remove.

6083 2003-08-21 Akim Demaille <akim@epita.fr>
6085 First stab at preserving warnings between calls to autom4te,
6086 including when the cache is used.
6088 There are still several issues: (i) there are too many runs of m4
6089 (one for include, one for warnings, and some more), (ii) warnings
6090 spreading on several lines are not handled gracefully, (iii) the
6091 code meant to have the call stack display for errors does not work
6092 (its handling should move from m4 to autom4te).
6094 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6095 Use them.
6096 (@preselect): Add m4_warn.
6097 ($exit_status): Remove, use $exit_code.
6098 ($help): Use Autom4te::ChannelDefs::usage.
6099 (&handle_m4): No longer define the m4_warnings.
6100 At each run, extract and report the warnings.
6101 Always cache the result, including if the exit status is on
6102 failure, since if nothing changes, we should result in the same
6103 failure, hence we can use the cache.
6104 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6105 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6106 Remove.
6107 (m4_warn): Redefine as a do-nothing: it is its invocation that
6108 matters, as warnings are now reported via traces.
6109 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6110 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6111 the latter reveals calls to the former.
6113 Adjust the tests.
6115 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6117 2003-08-21 Akim Demaille <akim@epita.fr>
6119 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6120 Use them.
6122 2003-08-21 Akim Demaille <akim@epita.fr>
6124 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6125 forward order.
6126 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6127 (&parse_warnings): Accept a list of warning requests.
6128 (&usage): Return a string, not a side effect.
6129 (cross): New warning category.
6131 2003-08-21 Akim Demaille <akim@epita.fr>
6133 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6134 (&require_configure_ac): Accept an optional directory argument.
6135 ($configure_ac): Remove.
6136 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6137 (&catfile): Remove.
6138 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6139 * bin/autoscan.in: Adjust.
6141 2003-08-20 Akim Demaille <akim@epita.fr>
6143 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6144 Reported by Alexandre Duret-Lutz.
6146 2003-08-20 Akim Demaille <akim@epita.fr>
6148 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6149 * bin/autom4te: Adjust.
6150 In particular, be Autoconf tools are really silent when properly
6151 working, bind the verbosity of the 'note' channel to $verbose.
6152 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6153 (&xsystem, &contents): Remove, since they are exported by...
6154 * lib/Autom4te/FileUtils.pm: this.
6155 More perldoc.
6156 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6157 * lib/Autom4te/FileUtils.pm: here.
6159 2003-08-20 Akim Demaille <akim@epita.fr>
6161 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
6162 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

6214 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
6215 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6216 shorter column three. Add DESCRIPTION to log file content.
6218 2003-08-13 Derek Price <derek@ximbiot.com>
6220 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6221 output.

6232 (AT_CHECK_NOESCAPE): ...to this new macro.
6234 2003-07-31 Paul Eggert <eggert@twinsun.com>
6236 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
6237 in Bash 2.01. Problem reported by Brian Gough in
6238 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

6249 Bob Friesenhahn.
6251 2003-07-06 Bill Clarke <llib@computer.org>
6253 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
6254 'long', not 'int', for benefit of Sun's recent C++ compilers
6255 (trivial change). See:
6256 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
6257 (This really should be 'intptr_t', not 'long', but that would
6258 take more work.)
6260 2003-06-25 Akim Demaille <akim@epita.fr>
6262 * lib/Makefile.am (autom4te.cfg): Make it read only.
6263 Depend on Makefile since it contains substitutions.

6276 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6277 not all of them. This fixes 1. the fact that when testing
6278 Autoconf there are many many config.log, 2. the incorrect use of
6279 top_srcdir to find config.log.
6280 Don't mix the detailed output of failed test with the summary of
6281 failures. Rather, append detailed log afterwards.
6283 2003-06-23 Akim Demaille <akim@epita.fr>
6285 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

6368 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6370 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6371 Do not call `_exit()', simply modify `$?'.

6382 Remove useless spaces in comments.
6384 2003-05-23 Akim Demaille <akim@epita.fr>
6386 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6387 exit 63, so that we (or Automake's "missing") can tell the
6388 difference with a plain failure.
6389 * doc/autoconf.texi (Notices): Adjust.
6391 2003-05-23 Akim Demaille <akim@epita.fr>
6393 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6394 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:

6397 2003-05-22 Jim Meyering <jim@meyering.net>
6398 Paul Eggert <eggert@twinsun.com>
6400 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6401 Remove `#include <stdlib.h>' from the list; we should never
6402 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6403 resulting namespace pollution would cause other tests to fail.
6404 Configure scripts run with some older versions of g++ and HP's
6405 aCC would fail due to such an #include. Problems reported by
6406 Matthew Mueller in <http://bugs.debian.org/120704> and by
6407 Keith Bostic in
6408 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6409 In the test, use the test declaration before including <stdlib.h>,
6410 as that's closer to how it'll be used.
6412 2003-05-23 Akim Demaille <akim@epita.fr>
6414 * doc/autoconf.texi (Header Portability): ucred.h.
6415 From Ian Redfern.
6417 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6419 Overhaul Autotest's logging: generate separate log files
6420 in testsuite.dir/NNN/testsuite.log, and append them to
6421 testsuite.log instead of re-running the test verbosely.
6423 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6424 file descriptor, write 0 to at_status_file instead of setting
6425 at_status=0, initialize some new variables (at_status_file,
6426 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6427 to rerun the tests, instead append the at_group_log to the
6428 at_suite_log when a test fails.
6429 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6430 with the AS_MESSAGE_LOG_FD redirected to stdout.
6431 (AT_CLEANUP): save the output status in $at_status_file
6432 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6433 its original place.
6434 (AT_CHECK): since tests are run with a redirected stdout,
6435 and used to be re-run in verbose mode, turn some $at_verbose
6436 into echo, and don't redirect the output of testing stdout
6437 and stderr.
6439 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6440 the name of the debugging directory and information about
6441 its contents.
6443 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6445 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6446 parameter.

6558 and truncate.
6560 2003-05-06 Akim Demaille <akim@epita.fr>
6562 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6563 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6564 by aclocal.m4 is changed it might require the importing of another
6565 m4 extension file, i.e., aclocal must be run.
6567 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6568 (&parse_args): Use --force with aclocal if required and supported.
6569 (&autoreconf_current_directory): Use &run_aclocal.

6576 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6577 argument instead of a file name, so that the request file remains
6578 open during the whole autom4te run.
6579 ($icache_file): New.
6580 (&freeze): Lock the $icache_file.
6582 2003-04-29 Derek Price <derek@ximbiot.com>
6584 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6585 seperator with m4_append_uniq(). It doesn't work.
6586 (AT_CLEANUP): Add `;' to end of at_help_all.
6587 (AT_INIT): Allow --keywords to be specified more than once. When
6588 grepping $at_help_all for keywords, use the field and keyword
6589 seperators to ensure a complete keyword match. Alter at_prev handling
6590 to support the new --keywords behavior.
6592 2003-04-27 Karl Berry <karl@freefriends.org>
6594 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6595 align better with others. I also made some of the individual
6596 entries on one line, for brevity and to make it easier for me to
6597 sort my dir-example file in the Texinfo distribution :).
6599 2003-04-12 Jim Meyering <jim@meyering.net>

6645 which removed the main loop.
6646 Thanks to Akim Demaille.
6648 2003-03-29 Akim Demaille <akim@epita.fr>

6652 From Ilya Zakharevich.
6654 2003-03-29 Akim Demaille <akim@epita.fr>

6658 Suggested by Paul Eggert.
6660 2003-03-28 Akim Demaille <akim@epita.fr>
6662 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest

6664 header causes problems.
6666 2003-03-28 Akim Demaille <akim@epita.fr>
6668 * tests/torture.at (Configuring subdirectories): Require aclocal
6669 1.4, otherwise the test fails, as it does support configure.ac.
6670 This fixes the "test 40 failed" bug reports.

6674 * doc/autoconf.texi (C Compiler): `#line' portability.

6741 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
6742 Tru64 make in the "target lookup" section.
6743 (Automake): Automake 1.5+ no longer requires special tools to be
6744 present on the developer's host.

6762 ${ac_make}.
6764 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6765 When constructing paths with IFS=:, quote the path. If we're
6766 constructing a DOS-style absolute path, we don't want to split it
6767 on the colon.

6785 to fix a mismatch between example and discussion.
6787 2003-02-24 Kevin Ryde <user42@zip.com.au>
6789 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6790 format starting with "-".
6792 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6794 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6795 is not portable inside Makefile.
6797 2003-02-20 Akim Demaille <akim@epita.fr>
6799 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6800 compiler says yeah, but preproc says nope, compiler is right.
6801 Conversely, prompt the reader to send a bug report to the
6802 maintainers of the package, not of Autoconf.
6804 2003-02-20 Klee Dienes <kdienes@apple.com>
6806 * bin/autoreconf.in (autoreconf_current_directory): Properly

6817 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6818 innocuous variant befor including <limits.h> or <assert.h>. This
6819 works around a bug reported by Albert Chin: HP-UX 11i
6820 (and earlier versions) have a <limits.h> that declares
6821 gettimeofday and many other functions.
6823 2002-12-03 Paul Eggert <eggert@twinsun.com>
6825 Version 2.57.
6827 * NEWS, configure.ac: Update version.
6829 * doc/fdl.texi: Upgrade to FDL version 1.2.
6831 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6832 nontrivially in main's body, so that f's external declaration is
6833 not optimized away in AIX. This should fix the bug reported by
6834 Martin Frydl in
6835 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6837 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6838 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6839 defined, to support freestanding compilers. This should fix the
6840 bug reported by Momchil Velkov in
6841 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6843 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6844 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
6845 obsolete AC_CHECK_TYPE. The missing empty arg was reported
6846 by Simon Josefsson in

6849 * Makefile.maint (www-gnu): New macro.
6850 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6851 the location has moved.
6853 2002-12-02 Martin Frydl <martin@systinet.com>
6855 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6856 \(.*\) match is too long and there is something more to be checked.
6857 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

6875 Update from masters.
6877 2002-11-14 Akim Demaille <akim@epita.fr>
6879 * Makefile.maint: Sync with Bison, i.e.:
6880 (po-check): Scan .l and .y files instead of the
6881 .c and the .h files that they generate. This fixes the bug
6882 reported by Tim Van Holder in:
6883 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6884 Look for N_ as well as for _. Try to avoid matching #define for
6885 N_ and _.
6886 From Paul Eggert.
6888 2002-11-14 Akim Demaille <akim@epita.fr>
6890 * doc/autoconf.texi (C Compiler): Compiling several files at once.

6898 2002-11-14 Kevin Ryde <user42@zip.com.au>
6900 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6901 than assigning in main, to avoid HP cc +O3 optimizing it away.
6903 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6905 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6906 option. Process --recheck after parsing all options. Pass -q
6907 option to configure on --recheck.
6908 (AC_OUTPUT): Pass -q from configure to config.status.
6909 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from

6911 * doc/autoconf.texi (config.status Invocation): Document
6912 config.status -q option.
6914 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

6917 Makefile.in if Makefile.am exists.

6939 Reported by Ezra Peisach.
6941 2002-11-05 Akim Demaille <akim@epita.fr>
6943 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6944 Remove.
6945 We _have_ to stop using the old compatibility scheme that tried to
6946 avoid useless backslashes because Libtool 1.4.3 contains a
6947 AC_DEFINE([error_t], [int],
6948 [Define to a type to use for \`error_t' if it is not
6949 otherwise available.])
6950 We _have_ to quote the single quote and backslashes with \. The
6951 old compatibility scheme saw that ` was backslashed, and therefore
6952 did not quote the single quote. Hence before this patch, Autoconf
6953 was not compatible with Libtool.
6955 2002-11-04 Paul Eggert <eggert@twinsun.com>
6957 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6997 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6998 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6999 Make variable, not a shell variable.
7000 Suggested by Bruno Haible.
7002 2002-10-31 Akim Demaille <akim@epita.fr>
7004 * bin/autom4te.in (load_configuration): Reject #args out of any
7005 language.

7021 Suggested by Tim van Holder.

7026 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
7027 Problem reported by Bruno Haible.
7029 2002-10-29 Akim Demaille <akim@epita.fr>
7031 * doc/autoconf.texi (Header Templates): Put also in words what the
7032 pictures says to assist free style readers.
7033 (Customizing autom4te): s/--cache=/--cache /.
7035 2002-10-29 Akim Demaille <akim@epita.fr>

7343 longer required can still cause errors.
7344 Reported by Alexandre Duret-Lutz.
7346 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

7365 format, so that Emacs' compile mode understands us.
7366 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7367 if some file was changed instead of `print'.
7368 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
7369 (&parse_args): Remove the dead options.
7370 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
7371 autoheader's quiet mode.
7372 (AT_CHECK_AUTOUPDATE): Likewise.
7373 * tests/tools.at (autoupdate): Adjust.
7374 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7376 2002-10-11 Akim Demaille <akim@epita.fr>
7378 No longer use CPP to check for the existing of headers: use CC to
7379 check for compilability.
7381 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
7382 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
7383 (_AC_CHECK_HEADER_NEW): Rename as...
7384 (AC_CHECK_HEADER): this.
7386 * lib/autotest/general.m4 (AT_INIT): Include the failed test
7387 numbers in the Subject suggestion.
7389 2002-10-11 Akim Demaille <akim@epita.fr>
7391 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
7392 Suggest using AC_CHECK_DECLS instead.
7394 2002-10-11 Akim Demaille <akim@epita.fr>
7396 * tests/torture.at (AC_ARG_VAR): Have configure report the value
7397 of `precious'.
7399 2002-10-11 Akim Demaille <akim@epita.fr>
7401 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
7402 file name to enable parallel executions.
7403 From Sam Varshavchik.
7405 2002-10-08 Akim Demaille <akim@epita.fr>
7407 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7408 aclocal invocation, as Gettext macros might not be visible to
7409 aclocal.
7410 Instead of blindly running autopoint, scan configure.ac (not the
7411 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7412 Reported by Paul D. Smith.
7414 2002-10-08 Paul Eggert <eggert@twinsun.com>
7416 Work around problems found when POSIXLY_CORRECT=1 is set.
7417 None of this seems to have anything to do with POSIX, really,
7418 but it's how Perl getopt works.
7419 * bin/autom4te.in (parse_args): Configure GetOpt with
7420 "permute", too.
7421 * doc/autoconf.texi (Invoking autom4te):
7422 --warning -> --warnings.
7423 * lib/autom4te.in: --warning -> --warnings.
7425 2002-09-28 Akim Demaille <akim@epita.fr>
7427 * doc/autoconf.texi (autom4te.cache): New section.
7429 2002-09-28 Akim Demaille <akim@epita.fr>
7431 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
7432 (Automake-preselections): Update.
7433 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
7435 2002-09-28 Akim Demaille <akim@epita.fr>
7437 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
7438 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
7439 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7440 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
7442 2002-09-28 Akim Demaille <akim@epita.fr>
7444 * tests/torture.at (Configuring subdirectories): Be robust to
7445 users who use config.site to require for a cache: in this case,
7446 the two last configure runs, using two different sets of
7447 arguments, trigger a legitimate error.
7449 2002-09-28 Akim Demaille <akim@epita.fr>
7451 * tests/m4sh.at (Functions Support, Functions and return Support):
7452 New.
7454 2002-09-28 Akim Demaille <akim@epita.fr>
7456 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
7457 autoheader are Perl programs.
7458 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
7459 (autom4te): Specify that the sources are in the $srcdir.
7460 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7462 2002-09-28 Akim Demaille <akim@epita.fr>
7464 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
7465 (tm_zone): Move their rules to...
7466 * lib/autoconf/types.m4: here, using AN_ macros.
7467 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7468 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7469 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7470 * lib/autoconf/programs.m4: here.
7471 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
7472 (ETAGS_FOR_AUTOCONF): New.
7473 Use it.
7475 2002-09-28 Akim Demaille <akim@epita.fr>
7477 * lib/autoconf/autoscan.m4: New file.
7478 * lib/autoconf/autoconf.m4: Include it.
7479 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
7480 that were listed in the original autoscan.list.
7481 * lib/autoconf/headers.m4: Similarly with headers.
7482 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7483 (.m4.m4f): Don't pass --prepend-include, since that's done by
7484 tests/autom4te itself.
7485 * lib/autoscan/Makefile.am: Include freeze.mk.
7486 (autoscan.list): New target --this file is no longer a source.
7487 (autoscan.pre): New file.
7489 2002-09-28 Akim Demaille <akim@epita.fr>
7491 * bin/autoscan.in (@kinds): Make them singular.
7492 Adjust all uses.
7493 (&init_tables): When --debug, report the list of rules to ease
7494 tracking changes in autoscan.list.
7495 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7497 2002-09-28 Akim Demaille <akim@epita.fr>
7499 * lib/autoscan/functions, lib/autoscan/headers,
7500 * lib/autoscan/identifiers, lib/autoscan/makevars,
7501 * lib/autoscan/programs: Merge into...
7502 * lib/autoscan/autoscan.list: this.
7503 * bin/autoscan.in (&init_tables): Adjust.
7505 2002-09-28 Akim Demaille <akim@epita.fr>
7507 * lib/autoscan/functions, lib/autoscan/headers,
7508 * lib/autoscan/identifiers, lib/autoscan/makevars,
7509 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7510 `functions' line is now prefixed with `function:'.
7511 * bin/autoscan.in (&init_tables): Adjust.
7513 2002-09-28 Akim Demaille <akim@epita.fr>
7515 From now on, autoscan files must always map a macro name to a
7516 word: there is no `default' macro for autoscan.
7518 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7519 all.
7520 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7521 explicit.
7523 2002-09-28 Akim Demaille <akim@epita.fr>
7525 * bin/autoscan.in (%c_keywords): Remove.
7526 (&used): Keep only track of the words we might be interested in.
7527 (&output_kind): It is no longer needed to look for non active
7528 checks.
7530 2002-09-27 Akim Demaille <akim@epita.fr>
7532 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
7533 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
7534 * lib/autoscan/functions: Adjust.
7535 * doc/autoconf.texi (Particular Functions): Adjust.
7537 2002-09-27 Akim Demaille <akim@epita.fr>
7539 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
7540 from /tmp.
7541 Thanks to Bill Moseley and Paul Eggert.
7542 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
7543 the tmpdir must be created.
7544 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
7545 dir be in the build tree, instead of $TMPDIR.
7547 2002-09-27 Akim Demaille <akim@epita.fr>
7549 * bin/autoscan.in: Improve the comments.
7550 (&parse_args): Drop obsolete undocumented options.
7551 (&output_kind): Output warnings.
7552 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
7553 (getwd): Trigger a warning.
7555 2002-09-26 Akim Demaille <akim@epita.fr>
7557 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7558 Reported by Ralf Corsepius.
7559 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7561 2002-09-26 Akim Demaille <akim@epita.fr>
7563 Single suffix rules and seperated dependencies are not portable.
7565 * doc/autoconf.texi (Installation Directory Variables): Update.
7566 (Limitations of Make): Some about `Single Suffix Rules and
7567 Separated Dependencies'.
7568 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7569 (ifnames, autoscan, autom4te): Un-factor into several rules.
7571 2002-09-25 Paul Eggert <eggert@twinsun.com>
7573 * BUGS (Interoperability bugs): New section. Mention libtool
7574 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7576 2002-09-24 Paul Eggert <eggert@twinsun.com>
7578 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7579 make handles suffix-rules differently from GNU make.
7581 * bin/Makefile.am (SUFFIXES, .in): Remove.
7582 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7583 Move the body of the old .in rule here.
7585 2002-09-16 Akim Demaille <akim@epita.fr>
7587 i960 compilers create `b.out' files by default.
7588 Reported by Ralf Corsepius.
7590 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7591 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7593 2002-09-13 Paul Eggert <eggert@twinsun.com>
7595 * doc/autoconf.texi (Particular Headers): Remove obsolete
7596 reference to `struct timezone' in the description of
7597 AC_HEADER_TIME.
7599 2002-09-13 Akim Demaille <akim@epita.fr>
7601 Version 2.54.
7603 * config/config.sub, config/config.guess: Update.
7604 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7605 * Makefile.am: Adjust.
7607 2002-09-13 Akim Demaille <akim@epita.fr>
7609 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7610 reading config.log when the compiler is rejected.
7611 Suggested by Guido Draheim.
7613 2002-09-13 Akim Demaille <akim@epita.fr>
7615 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7616 (chdir_init) might hang when stat'ing mounted directories.
7617 Reported by Vance Shipley.
7619 2002-09-12 Akim Demaille <akim@epita.fr>
7621 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7622 the lists.
7624 2002-09-12 Akim Demaille <akim@epita.fr>
7626 * doc/autoconf.texi (Defining Symbols): Present two different
7627 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7628 difference between 1 argument calls, and 2-3 argument calls.
7630 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7632 * doc/autoconf.texi: Review grammar and punctuation.
7634 2002-09-11 Paul Eggert <eggert@twinsun.com>
7636 * doc/autoconf.texi: Fix minor formatting, spelling, and
7637 grammatical typos.
7638 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7639 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7640 is obsolescent.
7642 2002-09-11 Akim Demaille <akim@epita.fr>
7644 * doc/autoconf.texi (Questions): Rename as...
7645 (FAQ): this.
7646 (Defining Directories): New.
7648 2002-09-09 Akim Demaille <akim@epita.fr>
7650 * doc/autoconf.texi (Making testsuite Scripts): Update.
7651 Suggested by Nishio Futoshi.
7653 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7655 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7656 plain `@' is wanted.
7658 2002-09-09 Akim Demaille <akim@epita.fr>
7660 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7661 `duplicates', since the algorithm was too naive and could keep
7662 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7663 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7664 Reported by Ralf Corsepius.
7665 * tests/torture.at (Configuring subdirectories): Exercise these
7666 cases.
7668 2002-09-09 Akim Demaille <akim@epita.fr>
7670 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7671 looking for a replacement file.
7672 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7673 directory is relative.
7674 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7675 directory definition.
7676 Reported by Andreas Schwab and Jim Meyering.
7678 2002-09-06 Akim Demaille <akim@epita.fr>
7680 * doc/autoconf.texi (Setting Output Variables): Clarify what
7681 precious variables are.
7682 Suggested by Pontus Skoeld.
7684 2002-09-05 Akim Demaille <akim@epita.fr>
7686 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7687 (ifnames, autoscan, autom4te): Since we don't only depend on
7688 configure.ac variables (such as VERSION etc.), but also on prefix
7689 and so forth, depend on Makefile, not configure.ac.
7690 Reported by Alexandre Duret-Lutz.
7691 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7693 2002-09-05 Kevin Ryde <user42@zip.com.au>
7695 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7696 doesn't seem to be confined to ia64, just say "some versions".
7698 2002-09-04 Akim Demaille <akim@epita.fr>
7700 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7701 Automake 1.6c.
7702 * Makefile.am (maintainer-clean-local): Remove.
7703 (MAINTAINERCLEANFILES): Remove COPYING.
7705 2002-09-03 Paul Eggert <eggert@twinsun.com>
7707 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7708 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7709 Brinkmann.
7711 2002-09-03 Akim Demaille <akim@epita.fr>
7713 * configure.ac: Bump to 2.53d.
7714 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7715 as of today, on Automake's team suggestion.
7717 2002-09-03 Akim Demaille <akim@epita.fr>
7719 Version 2.53c.
7721 2002-09-02 Akim Demaille <akim@epita.fr>
7723 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7724 SITE_MACRO_DIR.
7725 * configure.ac: Disable SITE_MACRO_DIR.
7727 2002-09-02 Jim Meyering <meyering@lucent.com>
7729 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7730 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7731 Also, tweak grammar: s/make sure to/be sure to/.
7733 2002-09-02 Paul Eggert <eggert@twinsun.com>
7735 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7736 directory names are generally preferable to physical names.
7738 2002-09-02 Akim Demaille <akim@epita.fr>
7740 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7741 Reported by Raja R. Harinath.
7742 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7743 * bin/autoupdate.in: Use error instead of die.
7745 2002-09-01 Paul Eggert <eggert@twinsun.com>
7747 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7748 ordinary shell concatenation rather than echo+tr+sed command that
7749 runs afoul of a long-line-related sed bug in Solaris 8.
7751 * bin/autoheader.in (parse_args): --warning -> --warnings.
7753 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7754 stdout, as traditional "ls" does.
7755 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7756 _AC_COMPILER_EXEEXT_O): Likewise.
7757 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7759 * bin/autoconf.as: Add --prepend-include option. This patch was
7760 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7761 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7763 * bin/autoconf.in, configure: Regenerate.
7765 * doc/autoconf.texi (Special Shell Variables): Mention
7766 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7768 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7769 MAILPATH and set PS1, PS2, PS4 to default values, to work
7770 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7771 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7772 the Autoconf documentation specifies; fall back to "unset" only if
7773 this fails. Use a shell for-loop for this rather than an m4 loop,
7774 to shorten the output script.
7776 2002-08-30 Paul Eggert <eggert@twinsun.com>
7778 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7779 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7780 for the CDPATH problem. Document PWD.
7781 (Limitations of Builtins): Document the problem that "cd $foo" and
7782 "ls $foo" may refer to different directories in shells conforming
7783 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7784 example, since the old example is now out of date.
7786 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7787 FOO" and "ls FOO" talk about different directories; this catches
7788 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7789 spaghetti.
7791 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7792 of rolling our own unset.
7793 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7794 in practice we needn't worry about CDPATH if unset doesn't work.
7796 * Makefile.in, aclocal.m4, bin/Makefile.in,
7797 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7798 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7799 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7800 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7801 tests/Makefile.in: Regenerate with Automake 1.6.3.
7803 * config/config.guess, config/config.sub, config/mkinstalldirs:
7804 Update.
7806 * configure: Regenerate with self.
7808 2002-08-30 Kevin Ryde <user42@zip.com.au>
7810 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7811 default output.
7813 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7815 * bin/autom4te.in (Request::load): Correctly test for "do" read
7816 failure.
7818 2002-08-29 Akim Demaille <akim@epita.fr>
7820 * lib/Autom4te/General.pm (&xqx): New.
7821 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7822 hand, which is not portable.
7823 (&error): New.
7824 * bin/autom4te.in: Use them.
7825 Use &error instead of die.
7826 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7827 Adjust.
7829 2002-08-17 Paul Eggert <eggert@twinsun.com>
7831 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7832 default list of compilers to try, since it was long ago superseded
7833 by the ksh fc builtin. Suggested by Steven G. Johnson.
7835 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7837 * doc/autoconf.texi (Invoking autom4te): End the option table,
7838 fixing a bug introduced by the previous patch.
7839 (Limitations of Make): Add a 'target lookup' subentry in the
7840 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7842 2002-07-29 Mark D. Roth <roth@feep.net>
7844 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7845 options and use $AUTOM4TE_PATH.
7846 * doc/autoconf.texi: Remove documentation of autom4te
7847 --include-envvar and --site-macro-subdir options and document
7848 use of $AUTOM4TE_PATH.
7849 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7850 arguments from each language section.
7852 2002-07-29 Paul Eggert <eggert@twinsun.com>
7854 * doc/install.texi: Include copyright symbol in copyright notice.
7856 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7857 Replace with:
7858 (AM_MAKEINFOFLAGS): New macro.
7859 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7860 * Makefile.am (INSTALL): Use the new macros.
7861 Use -o rather than --output, since "missing" does not grok --output.
7863 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7865 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7866 comments do not always work. Never trust the exit status of
7867 `make -k'.

7871 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7872 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7874 2002-07-23 Paul Eggert <eggert@twinsun.com>
7876 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7877 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7878 apparently treats PATH="nonexistent" as if it contained ".".
7879 Bug reported by Stefan `Sec' Zehl.

8001 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
8002 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
8003 so that Emacs setups GNU style for perl-mode and cperl-mode.
8005 2002-06-27 Paul Eggert <eggert@twinsun.com>
8007 * config/install-sh: Quote $src. Prefer || to test's -o option,
8008 as per "Limitations of Builtins".
8009 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
8010 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8012 * tests/mktests.sh: Use grep instead of fgrep, as per
8013 "Limitations of Builtins".
8015 2002-06-15 Paul Eggert <eggert@twinsun.com>
8017 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,

8019 so that we consistently test the just-built programs.

8032 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
8033 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
8034 on Solaris 2.5.1.
8036 2002-06-11 Andreas Schwab <schwab@suse.de>
8038 * doc/autoconf.texi: Add more dir entries.
8040 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
8042 * bin/autom4te.in ($cache): Don't define using `$me', the name
8043 of the cache should not depend on the name under which autom4te
8044 was installed.
8046 2002-06-07 Akim Demaille <akim@epita.fr>
8048 * tests/tools.at (autoconf: forbidden tokens, basic)

8050 words in autom4te.in.
8052 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8054 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
8055 _AC_LANG_PROGRAM_C_F77_HOOKS.
8057 2002-06-07 Akim Demaille <akim@epita.fr>
8059 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
8060 rename as...

8063 AC_FUNC_FNMATCH_GNU.
8065 2002-06-07 Akim Demaille <akim@epita.fr>
8067 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
8068 Rosetta Stone for Unix.
8070 2002-06-07 Akim Demaille <akim@epita.fr>
8072 * bin/autom4te.in (warn_forbidden): When rejecting a token,
8073 suggest m4_pattern_allow.
8074 Suggested by Adam J. Richter.
8076 2002-06-07 Akim Demaille <akim@epita.fr>
8078 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
8079 ac_config_libobj_dir.
8080 (AC_CONFIG_LIBOBJ_DIR): New.
8081 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
8082 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
8083 Use ac_config_libobj_dir to find the replacement files.
8084 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...

8088 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
8089 * tests/mktests.sh (ac_exclude_list): Don't check

8092 2002-06-06 Paul Eggert <eggert@twinsun.com>
8094 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
8095 if ln doesn't work.
8096 * NEWS: Likewise.
8097 * doc/autoconf.texi (Configuration Links): Likewise.
8098 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
8100 2002-06-05 Paul Eggert <eggert@twinsun.com>
8102 * config/config.guess, config/config.sub, config/texinfo.tex:
8103 Update from masters.
8105 2002-05-29 Paul Eggert <eggert@twinsun.com>
8107 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.

8135 version of Autoconf that is discussed.
8137 2002-05-22 Paul Eggert <eggert@twinsun.com>
8139 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8140 from the default list of compilers to try. Suggested by
8141 Kate Hedstrom.
8142 * NEWS: Document the above.
8143 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8145 2002-05-17 Paul Eggert <eggert@twinsun.com>
8147 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8148 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8149 This improves on an earlier suggestion by H. Peter Anvin.
8151 2002-05-16 Paul Eggert <eggert@twinsun.com>
8153 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8154 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8155 Both macros now accept an optional source-dir arg.
8156 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8158 * NEWS: Document this.
8159 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8161 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8162 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8163 not for GNU extensions; this undoes part of the 2000-11-03 change,
8164 reverting to 2.13-compatible behavior.
8165 Add new optional argument DIR.
8166 (AC_FUNC_FNMATCH_GNU): New macro.
8168 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8170 2002-05-08 Paul Eggert <eggert@twinsun.com>
8172 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8173 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8174 and it causes a 'test' syntax error if it fails.
8175 Bug reported by Stephen Gildea.
8177 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8178 If prototypes are supported, use them to check this at compile-time,
8179 instead of trying to check it at run-time. If we must do a run-time
8180 check, assume that setvbuf is standard when cross-compiling, as
8181 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8182 Bug reported by Paul D. Smith.
8184 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8185 argument specifying location of getloadavg.c. This removes a
8186 FIXME. This idea was taken from Jim Meyering's implementation in
8187 textutils.
8188 * doc/autoconf.texi (Particular Functions): Document this.
8189 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8190 that's what the code does; this fixes a bug reported by
8191 Paul D. Smith.
8193 2002-05-03 Akim Demaille <akim@epita.fr>
8195 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8196 autopoint instead of gettextize.
8197 ($uses_alocal): Rename as...
8198 ($uses_aclocal): this.
8199 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8200 Suggested by Bruno Haible.
8202 2002-05-03 Akim Demaille <akim@epita.fr>
8204 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8206 2002-04-29 Paul Eggert <eggert@twinsun.com>
8208 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8209 files to be 1 second older; just set them to be the same time.
8210 Also, sleep 1 second after the first aclocal, to work around
8211 problems with sub-second time stamps on the input files.
8213 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8215 * doc/autoconf.texi: Mention "set -e -x" lossage
8216 under node "Limitations of Builtins".
8218 2002-04-29 Akim Demaille <akim@epita.fr>
8220 * doc/install.texi: Better wording for setting variables when
8221 running configure.
8222 From Christian Cornelssen.
8224 2002-04-29 Akim Demaille <akim@epita.fr>
8226 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8227 of lack of $LINENO support, then the test will compare the $LINENO
8228 in testsuite vs. the lineno in the test file. This is wrong, of
8229 course.
8230 Be sure to protect it.
8231 Reported by Patrick Welche.
8233 2002-04-25 Akim Demaille <akim@epita.fr>
8235 * doc/autoconf.texi (Obsolete Macros): Typo.
8236 Reported by Vladimir Volovich.
8238 2002-04-25 Akim Demaille <akim@epita.fr>
8240 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8241 than some of the input files, hence, on the second run of aclocal,
8242 if some of its input are younger, make them older.
8243 Suggested by Paul Eggert.
8245 2002-04-25 Akim Demaille <akim@epita.fr>
8247 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8248 Thanks to Paul Eggert.
8250 2002-04-25 Akim Demaille <akim@epita.fr>
8252 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8253 and ac_subst_vars be sh variables containing the list of
8254 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8255 DEFAULT diversion.
8256 (_AC_INIT_PREPARE): Use them to log them.
8257 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8258 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8259 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8260 _AC_SUBST_FILES and _AC_SUBST_VARS.
8261 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8263 2002-04-24 Akim Demaille <akim@epita.fr>
8265 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8266 autoheader, so that automake does not complain about a missing
8267 config.h.in that was to be created.
8269 2002-04-23 Akim Demaille <akim@epita.fr>
8271 * bin/autoheader.in (parse_args): --warning takes an argument.
8272 Fixes PR/220.
8274 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
8276 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

8291 Reported by Gregory Giannoni.
8293 2002-04-22 Akim Demaille <akim@epita.fr>
8295 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.

8324 Sample Texts sections of the Texinfo 4.2 manual. Most
8325 importantly, this makes sure that the copyright notices appear in
8326 all output formats. You probably need Texinfo 4.2 to generate

8355 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8356 from aclocal.m4 too.
8358 2002-04-12 Akim Demaille <akim@epita.fr>
8360 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
8362 2002-04-10 Akim Demaille <akim@epita.fr>
8364 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8365 workaround for ${1+"$@"}.
8366 * doc/autoconf.texi (Shell Substitutions): Explain it.
8367 From Oliver Kiddle and Peter Stephenson.
8369 Have M4sh perform minimal shell sanitizing.
8371 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8372 part into...
8373 (_AS_PREPARE): this new macro.

8376 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8378 Adjust Autoconf and Autotest.

8381 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8382 * lib/autotest/general.m4 (AT_INIT): Likewise.
8383 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8384 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8385 AS_SHELL_SANITIZE.
8387 Use this M4sh to generate Autoconf's shell scripts.
8389 * tests/wrapsh.as: New, precursor of wrapsh.in.
8390 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8391 on Autotest and M4sh.
8392 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8393 (wrapsh.in): New target.
8394 * bin/autoconf.as: New, precursor of autoconf.in.
8395 (autoconf.in): New target.
8397 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
8399 * doc/autoconf.texi (Limitations of Make): Mention the issue
8400 with indented comments in rules.

8410 (Portable Shell): Cross reference to Systemology.
8412 2002-04-05 Akim Demaille <akim@epita.fr>

8415 directories when descending in a SUBDIRS.
8416 Reported by Ezra Peisach.
8418 2002-04-04 Andreas Schwab <schwab@suse.de>
8420 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8421 contains no literal separators.
8423 2002-04-03 Akim Demaille <akim@epita.fr>
8425 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8426 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8427 Use dnl, not the KILL diversion.
8428 Extracted from...
8429 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8430 (AC_CONFIG_LINKS): here.
8431 Adjust.
8432 Don't use the KILL diversion, as it kills spurious output, which
8433 results in failures being hidden.
8434 Use m4_defn where appropriate.
8435 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8436 after the second argument.
8437 Use m4_defn.
8438 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8439 syntax, as it is provided by M4sugar.

8481 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8482 to avoid versions of HP C which don't allow that.
8484 2002-03-27 Paul Eggert <eggert@twinsun.com>
8486 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8487 (AS_SHELL_SANITIZE): Invoke it.

8494 2002-03-26 Akim Demaille <akim@epita.fr>
8496 * doc/autoconf.texi (Introduction): The GNATS base moved.
8498 2002-03-25 Paul Eggert <eggert@twinsun.com>
8500 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8501 as POSIX requires, as it doesn't work with Zsh.
8502 * doc/autoconf.texi (Assignments): Document the problem.
8504 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8506 * doc/autoconf.texi (Limitations of Make): Mention more issue
8507 about VPATH, overriding of macros in sub-makes, and handling of
8508 SHELL.
8510 2002-03-21 Paul Eggert <eggert@twinsun.com>
8512 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8513 problem with here-document buffer boundaries.
8515 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8516 when reinvoking the shell, to work around problems with installers
8517 who put strange things like "cd" commands in their environments.
8519 2002-03-19 Akim Demaille <akim@epita.fr>
8521 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8522 From Aaron Ucko.
8524 2002-03-19 Akim Demaille <akim@epita.fr>
8526 * bin/autoscan.in (scan_file): Specify the location in `&used'
8527 invocations.
8528 From Nicolas Joly.
8530 2002-03-19 Akim Demaille <akim@epita.fr>
8532 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8533 From Nishio Futoshi.
8535 2002-03-19 Akim Demaille <akim@epita.fr>
8537 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

8541 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8542 (Limitations of Usual Tools): Add mkdir section.
8544 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8545 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8546 back on AS_DIRNAME to compute prefixes otherwise; this is
8547 roughly what mkinstalldirs does. That way, we need not have
8548 our own filename disassembler. The old disassembler did not
8549 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8551 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8552 Create at_test_all by a series of assignments,
8553 not by a single assignment of a long string. The latter causes ksh
8554 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8555 presumably because of a buffer overrun.
8557 2002-03-14 Paul Eggert <eggert@twinsun.com>
8559 * lib/autotest/general.m4 (at_times_skip):
8560 Renamed from at_times. Now a boolean.
8561 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8562 says 'times: not found'.
8564 2002-03-14 Akim Demaille <akim@epita.fr>
8566 * bin/autoreconf.in (&study_gettextize): New.
8567 (&autoreconf): Handle newest gettextize.
8568 Rerun aclocal if needed.
8569 Suggested by Andreas Schwab.
8571 2002-03-13 Akim Demaille <akim@epita.fr>

8578 Add information about stdint.h and inttypes.h from Paul Eggert.
8580 2002-03-13 Akim Demaille <akim@epita.fr>
8582 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8583 -p'.
8584 From Bob Proulx.
8586 2002-03-12 Akim Demaille <akim@epita.fr>
8588 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8589 m4_require.
8591 2002-03-11 Andreas Schwab <schwab@suse.de>
8593 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8594 does not do it if --with-lispdir is given.
8596 2002-03-08 Akim Demaille <akim@epita.fr>
8598 Version 2.53.
8600 2002-03-08 Akim Demaille <akim@epita.fr>
8602 * doc/autoconf.texi (Subdirectories): Clarify that the
8603 subdirectory should exist.
8605 2002-03-08 Akim Demaille <akim@epita.fr>
8607 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8609 2002-03-08 Akim Demaille <akim@epita.fr>
8611 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8612 aliases the actual variables, and modifications of the former
8613 affect the latter.
8615 2002-03-08 Akim Demaille <akim@epita.fr>
8617 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8618 because of C-c: have m4 output in tmp files, then mv them.
8620 2002-03-08 Akim Demaille <akim@epita.fr>
8622 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8623 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8624 * bin/ifnames.in: Copyright update.

8630 2002-03-05 Akim Demaille <akim@epita.fr>
8632 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8633 Kevin Ryde.
8635 2002-03-05 Akim Demaille <akim@epita.fr>

8641 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8642 * lib/autoconf/general.m4 (AC_INIT): More informative error
8643 message for LIBOBJ.
8645 2002-03-04 Akim Demaille <akim@epita.fr>
8647 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8648 parallel builds.
8650 2002-03-04 Akim Demaille <akim@epita.fr>
8652 * doc/autoconf.texi (Transforming Names): Equality between target
8653 and host is irrelevant.
8654 (Specifying Names, Canonicalizing): Remove all references to the
8655 backward compatibility hooks. Rather, collect them all into...
8656 (Hosts and Cross-Compilation): this new section.
8657 * doc/install.texi (System Type): Ditto.
8658 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8659 that `--host' implies cross-compilation.
8661 2002-03-04 Akim Demaille <akim@epita.fr>
8663 * doc/autoconf.texi (Evaluation Macros): New.
8664 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8665 useless.
8666 (_m4_foreach): Define the variant with immediate evaluation so
8667 that it contains exactly the items, not an expression which
8668 evaluation is the current item.
8669 (m4_re_string, m4_re_word): Don't over quote them.
8671 2002-03-04 Akim Demaille <akim@epita.fr>
8673 Instead of having stacking `shift's evaluated at the end, let
8674 `foreach' loops immediately evaluate them.
8676 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8677 $*. This is the n-th time I change my mind, but hopefully this is
8678 the last...
8679 (m4_lquote): New.
8680 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8681 efficient.
8682 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8683 it was only a hack for m4_text_wrap.
8684 (m4_car2): Remove, replaced by...
8685 (m4_cdr): New.
8686 (_m4_foreach): Adjust.
8687 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8688 m4_bpatsubst for clarification.

8740 AC_PREFIX_PROGRAM fails with dashed program names
8742 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8743 variable when looking for the prefix program.
8744 Now it also works for shell variables.

8749 case/esac.

8777 to this file.

8781 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

8803 * bin/autom4te.in (&parse_args): Implement `frozen files are
8804 optional are the sum of the previous files on the command line'.
8805 Also, pass `--reload-state=' on them, so...
8806 (handle_m4): don't.
8807 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.

8816 2002-01-30 Akim Demaille <akim@epita.fr>
8818 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8819 alphanumeric to `-' instead of `_'.
8821 2002-01-30 Akim Demaille <akim@epita.fr>
8823 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8824 for plain code, the other for cross-compilation code. The latter
8825 is now run with GCC only.
8826 * doc/autoconf.texi (Compilers and Preprocessors): New.
8828 2002-01-30 Akim Demaille <akim@epita.fr>
8830 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8831 values.
8832 * doc/autoconf.texi (Initializing configure): Explain how to
8833 change AC_INIT default values.
8835 2002-01-29 Akim Demaille <akim@epita.fr>
8837 * tests/torture.at (Configuring subdirectories): Use configure.in,
8838 so that aclocal 1.4 works.
8839 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8841 2002-01-28 Akim Demaille <akim@epita.fr>
8843 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8844 needs an argument.
8846 2002-01-28 Akim Demaille <akim@epita.fr>
8848 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8849 AUTOTEST_PATH *after* it was set.
8850 Don't put `.' in the PATH: the user should be precise and `./' if
8851 needed. In addition, given that the test suite does some `cd', if
8852 `.' is in the path, the `tested programs' sections will report
8853 programs found in the test suite's directory, while during the
8854 tests (performed in their own directory), these programs are no
8855 longer visible. In other words, the results is confusing and
8856 useless.
8857 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8859 2002-01-24 Akim Demaille <akim@epita.fr>
8861 Version 2.52g.

8922 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8923 package.m4, since is really depends upon configure.ac, not
8924 configure.
8925 * doc/autoconf.texi (testsuite Scripts): Adjust.
8926 * tests/Makefile.am (package.m4): New.
8927 EXTRA_DIST it since its a source.
8929 2002-01-06 Akim Demaille <akim@epita.fr>
8931 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8932 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8933 and PACKAGE_BUGREPORT from here...
8934 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8935 arguments.
8936 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8937 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8938 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8939 * tests/tools.at (autoheader): Adjust.

8957 2001-12-17 Jim Meyering <meyering@lucent.com>
8959 * doc/autoconf.texi (New Macros): Tweak wording.
8961 2001-12-14 Akim Demaille <akim@epita.fr>
8963 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8964 trailing files, don't apply `-rf' to files which might not be
8965 created by configure (core, core.*, and *.core), but just `rm -f'.
8966 Suggested by Jonathan Kamens.
8968 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8970 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8972 2001-12-14 Akim Demaille <akim@epita.fr>
8974 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8976 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

8979 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8980 abs_srcdir, top_srcpath to abs_top_srcdir.
8981 (_AC_OUTPUT_FILES): Adjust.
8982 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8983 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8984 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8986 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8988 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed

8992 2001-12-12 Kevin Ryde <user42@zip.com.au>
8994 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8995 forbidden file descriptors table.
8997 2001-11-26 Akim Demaille <akim@epita.fr>
8999 * bin/autoscan.in (%c_keywords): Build it at top level.
9000 Map to 1 in order to simplify its uses.
9002 2001-11-26 Akim Demaille <akim@epita.fr>
9004 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9005 Remove $filepath, useless.
9006 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9007 variables, they are really part of the tokens.
9008 Split the input line on spaces and then look for tokens.
9009 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9010 because of `lex$U.$(OBJEXT)'.
9011 (&scan_files): Use "@list" instead of join.
9012 * doc/Makefile.am (CLEANFILES): Add *.fns.
9014 2001-11-26 Akim Demaille <akim@epita.fr>

9021 * lib/autoscan/headers: errno.h is portable.
9023 2001-11-26 Akim Demaille <akim@epita.fr>
9025 * bin/autoscan.in (used): New.
9026 Use it.
9028 2001-11-26 Akim Demaille <akim@epita.fr>
9030 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9031 directives.
9032 (&scan_sh_file): Remove a duplicate pattern.
9033 (&check_configure_ac): Use long options.
9034 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9036 2001-11-26 Akim Demaille <akim@epita.fr>
9038 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9039 Before, having a line containing the opening of a multi line
9040 comment made the whole line be ignored.
9042 2001-11-26 Akim Demaille <akim@epita.fr>
9044 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9045 (testsuite Scripts): Be one of its subsection.
9046 (Autotest Logs): New.
9048 2001-11-26 Akim Demaille <akim@epita.fr>
9050 Test groups are now run two directories deeper.
9052 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9053 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9054 at_top_builddir.
9055 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9056 top_srcdir, builddir and top_builddir.
9057 Use `at_*dir' relatively to the directory containing the
9058 suite, use `*dir' when relatively to the current group dir.
9060 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9062 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9063 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9064 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9065 spelling errors.
9067 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9069 * doc/autoconf.texi (Using System Type): Add an example of `case
9070 $host' usage so people quit using `case $target' everywhere.
9072 2001-11-22 Akim Demaille <akim@epita.fr>
9074 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9075 spotted by Jim Meyering.
9077 2001-11-16 Paul Eggert <eggert@twinsun.com>
9079 This patch implements a `long double' suggestion by Oliver Kiddle.
9081 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9082 static, to catch errors if the value isn't known at compile-time
9083 and the compiler supports dynamic arrays. Change its name from
9084 `_array_' to `test_array' to avoid potential name clashes.
9085 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9086 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9087 better than double. Catch a bug in GCC 2.95.2 x86.
9088 * doc/autoconf.texi (C Compiler): Document the above.
9089 * NEWS: Likewise.
9091 2001-11-13 Akim Demaille <akim@epita.fr>
9093 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9094 hand.
9095 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9097 2001-11-13 Akim Demaille <akim@epita.fr>
9099 * lib/autotest/general.m4 (AT_INIT): After having run the test
9100 group, go back to the initial directory, not to at_suite_dir.
9102 2001-11-13 Akim Demaille <akim@epita.fr>
9104 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9105 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9106 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9107 option.
9108 (AT_CHECK_CONFIGURE): Use absolute paths.
9109 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9110 The problem is still the old one: there is no means in M4 (that I
9111 know about) to create a defining macro, because there is no means
9112 to create `$1' etc., therefore, the defining macro ``swallows''
9113 all the arguments meant to the defined macro.
9115 2001-11-13 Akim Demaille <akim@epita.fr>
9117 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9118 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9119 configure.ac.
9120 * tests/aclocal.m4: Remove, as it is no longer used.
9122 2001-11-13 Akim Demaille <akim@epita.fr>
9124 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9125 variable names when referring to a single test group, or to
9126 `suite' when referring to the whole test suite.
9127 `at_last_test' is removed: m4 compute at_format itself.
9128 (at_stdout, at_stder1, at_stderr): New variables.
9129 (AT_CHECK): Use them.
9131 2001-11-13 Akim Demaille <akim@epita.fr>
9133 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9134 in PATH.
9135 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9136 Do it as soon as a test fails, don't wait till the end of the test
9137 suite.
9138 Don't remove $as_me.[0-9]*, since these files no longer exist.
9140 2001-11-13 Akim Demaille <akim@epita.fr>
9142 * tests/tools.at: Use absolute paths, since we are no longer run
9143 in place.
9145 2001-11-13 Akim Demaille <akim@epita.fr>
9147 Now that tests are running in their own private dir, there is no
9148 need to list the files to remove at the end of tests groups.
9150 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9151 (AT_data_files, at_data_files): Remove.
9152 (AT_CLEANUP, AT_DATA): Simplify.
9153 (AT_INIT): Adjust.
9154 Remove the group dir if !debug && !failed.
9155 * tests/atspecific.m4: Adjust.
9157 2001-11-13 Akim Demaille <akim@epita.fr>
9159 Start a new layout for Autotest: `testsuite' creates
9160 `testsuite.dir' in which the at-check-line etc. files are to be
9161 found, and `testsuite.dir/003' where the test group 3 is run.
9163 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9164 at_check_line_file, at_format, at_test_normalized, at_group_dir
9165 are new variables.
9166 Create the directories.
9167 Use absolute paths for at- files.
9168 (AT_CHECK): Adjust.
9170 2001-11-11 Michael Matz <matz@kde.org>
9172 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9173 (m4_car2): New.
9174 (m4_car): Properly quote arguments.
9176 2001-11-13 Akim Demaille <akim@epita.fr>
9178 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9179 with stricter rules on LIBOBJS.
9181 2001-11-12 Paul Eggert <eggert@twinsun.com>
9183 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9184 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9185 __PROTOTYPES too.
9187 2001-11-12 Akim Demaille <akim@epita.fr>
9189 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9191 2001-11-12 Akim Demaille <akim@epita.fr>
9193 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9194 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9195 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9196 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9197 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9198 specify to what the macro should be defined (typically to 1).
9200 2001-11-12 Akim Demaille <akim@epita.fr>
9202 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9203 From Jim Meyering.
9205 2001-11-12 Akim Demaille <akim@epita.fr>
9207 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9208 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9209 definition used by Automake where LEX is +/- "${missing} lex" and
9210 `missing' itself contains variables.
9212 2001-11-12 Akim Demaille <akim@epita.fr>
9214 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9215 Now that M4sh pushes BODY, the comments were output at the end of
9216 the test suites.
9218 2001-11-08 Akim Demaille <akim@epita.fr>
9220 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9221 that we can trace macros from aclocal.m4.
9222 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9223 obsoleted, and redirect to the former anyway.
9224 Reported by Ralf Corsepius.
9226 2001-11-08 Akim Demaille <akim@epita.fr>
9228 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9229 processed only if present.
9230 * tests/torture.at (Configuring subdirectories): Use autoreconf
9231 instead of successive calls to autoconf.
9232 Add a nonexistent subdirectory to exercise the patch above.
9233 Reported by Ralf Corsepius.
9235 2001-11-08 Kevin Ryde <user42@zip.com.au>
9237 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9238 doesn't accept .S files.
9240 2001-11-07 Akim Demaille <akim@epita.fr>
9242 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9243 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9244 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
9245 * bin/autom4te.in (warn_forbidden): New.
9246 (handle_output): Use it.
9247 Read m4_pattern_forbid with messages.
9249 2001-11-05 Akim Demaille <akim@epita.fr>
9251 * bin/autom4te.in (--normalize): Remove.
9252 * lib/autom4te.in: Adjust.
9254 2001-11-05 Akim Demaille <akim@epita.fr>
9256 * tests/Makefile.am (testsuite): Rename this target as...
9257 ($(TESTSUITE)): this.
9258 From Nicolas Joly.
9260 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9262 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9263 the --prefix option, also remove it's argument.
9265 2001-11-05 Akim Demaille <akim@epita.fr>
9267 * doc/autoconf.texi (testsuite Invocation): Update.
9268 (Writing testsuite.at): Update.
9270 2001-11-03 Akim Demaille <akim@epita.fr>
9272 * doc/autoconf.texi: s/@code/@command/ where appropriate.
9274 2001-11-03 Akim Demaille <akim@epita.fr>
9276 * lib/Autom4te/General.pm: (&catfile, &canonfile)
9277 (&file_name_is_absolute): New, wrappers around routines from
9278 File::Spec.
9279 Use and export them.
9280 (&find_configure_ac): Optionally take a directory where to look at.
9281 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
9282 the arguments.
9283 Default @ARGV to `.', not find_configure_ac.
9284 (&autoreconf): Argument is a directory.
9285 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
9286 * doc/autoconf.texi (autoreconf Invocation): Update.
9288 2001-11-03 Akim Demaille <akim@epita.fr>
9290 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9291 (@export_forward_subs): New.
9292 Add basename, dirname, and fileparse.
9293 (@EXPORT): Adjust.
9294 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9295 Don't look for aclocal flags if we already know aclocal is not
9296 used.
9297 Move aclocal.m4t only if it exists.
9298 Reported by Ezra Peisach.
9300 2001-11-03 Akim Demaille <akim@epita.fr>
9302 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9303 passed on command line, defaulting to ./configure.ac if present.
9304 (&maybe_autoreconf, File::Find): Remove, unused.
9305 (&autoreconf): If autoconf is not used, don't try to trace.
9307 2001-11-02 Akim Demaille <akim@epita.fr>
9309 * configure.ac: Bump to 2.52g.
9311 2001-11-02 Akim Demaille <akim@epita.fr>
9313 Version 2.52f.
9315 2001-11-02 Akim Demaille <akim@epita.fr>
9317 * config/config.guess, config/config.sub, doc/standards.texi:
9318 * config/lispdir.m4: Update from masters.
9319 * configure.ac: Bump to 2.52f.
9321 2001-11-02 Akim Demaille <akim@epita.fr>
9323 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9324 Don't run aclocal when aclocal.m4 is not from aclocal.
9325 From Ezra Peisach.
9326 Don't run libtoolize and gettextize if --install is not given.
9328 2001-11-01 Paul Eggert <eggert@twinsun.com>
9330 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9331 be invoked before _AS_LINENO_PREPARE.
9332 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9333 than character ranges.
9335 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9336 invoking AS_BASENAME. Set the locale variables to 'C' if
9337 possible, as POSIX requires this to get the traditional
9338 behavior.
9339 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9341 2001-10-31 Paul Eggert <eggert@twinsun.com>
9343 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9344 with {}, as that triggers a bug in Bash 2.05.
9346 (_AS_LINENO_PREPARE): Use Sed rather than
9347 Awk. Fix the sed prepass to work even if there are multiple
9348 instances of $LINENO on the same line. Do not substitute for
9349 other variables like $LINENOT. Do not check file dates; such a
9350 check is unreliable on sufficiently fast machines, and removing
9351 the check makes the code simpler and more reliable. Check for
9352 output and chmod failures.
9354 * doc/autoconf.texi (Special Shell Variables): Document
9355 the above.
9357 2001-10-31 Akim Demaille <akim@epita.fr>
9359 * tests/Makefile.am (atconfig): Remove this target, Automake
9360 handles it now.
9362 2001-10-31 Akim Demaille <akim@epita.fr>
9364 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9365 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9366 provided, while it is optional.
9367 * configure.ac: Adjust.
9369 2001-10-26 Paul Eggert <eggert@twinsun.com>
9371 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9372 lib/Autom4te/Struct.pm:
9373 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9374 with 5.005_02.
9376 * doc/autoconf.texi (Special Shell Variables): Document some
9377 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9379 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9380 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9381 eval $LINENO is not portable in practice.
9383 2001-10-24 Akim Demaille <akim@epita.fr>
9385 * lib/Autom4te/General.pm (backname): New.
9387 2001-10-24 Akim Demaille <akim@epita.fr>

9397 2001-10-22 Paul Eggert <eggert@twinsun.com>
9399 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9400 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9401 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9402 POSIX decided to standardize on the int flavor of strerror_r.
9403 Always do char* test, as there's no reason not to.
9404 Assign to a char* var, to catch strerror_r that returns int*.
9406 * doc/autoconf.texi (Particular Functions):
9407 Document the above changes. Also, document the fact that
9408 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9410 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9412 2001-10-20 Akim Demaille <akim@epita.fr>

9419 * lib/Autom4te/General.pm (&update_file): If destination is
9420 unchanged, remove the source.

9422 * bin/autoreconf.in: No longer support --m4dir.
9423 (&autoreconf): Display the full path of the configure.ac we are
9424 studying.
9425 Trace it only once.
9426 Be sure to honor --force with gettextize.
9427 Always run aclocal.
9428 * doc/autoconf.texi: Adjust.
9430 2001-10-20 Akim Demaille <akim@epita.fr>
9432 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9433 Remove, dead.
9434 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9435 `intl' is already present, as it refuses unless --force.
9436 (&parse_args): Use -I, --include instead of the old Autoconf
9437 options.
9438 ($localdir, $autoconf_dir): Remove.
9439 (@include): New.
9440 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9442 2001-10-19 Jens Petersen <petersen@redhat.com>
9444 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9456 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9457 comment, explain how to install automatic mode selection.
9458 From Russ Allbery.
9460 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9462 * bin/autoreconf.in (autoreconf): Display the path to the
9463 configure.ac being studied.
9465 2001-10-18 Paul Eggert <eggert@twinsun.com>
9467 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9468 long, to work around a bug in the HP C compiler version HP92453-01
9469 B.11.11.23709.GP.
9471 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9472 (AS_BASENAME_EXPR): New macro.
9473 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9474 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9475 and fall back on 'sed' only if the other two fail. This makes
9476 AS_BASENAME act more like AS_DIRNAME.
9477 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9478 contains white space.
9479 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9480 Use AS_DIRNAME, since I think it's now DOS-friendly.
9481 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9482 Allow "dirname //FOO" to return either / or //, as POSIX allows
9483 either behavior.
9485 2001-10-10 Akim Demaille <akim@epita.fr>
9487 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

9493 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9531 (Syntax of the shell scripts): Don't.
9532 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
9533 bother with $force since...
9534 * lib/Autom4te/General.pm: does.
9536 2001-10-08 Akim Demaille <akim@epita.fr>
9538 * bin/autoreconf.in: Rewrite in Perl.
9539 * configure.ac: Adjust.

9619 CONFIG_SHELL defaults to a shell that supports LINENO if available.
9621 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
9622 shell does not support LINENO, and if CONFIG_SHELL is unset or
9623 empty, and if we can find a shell that does support LINENO,
9624 then set CONFIG_SHELL to that shell and then re-execute
9625 ourselves with CONFIG_SHELL.
9627 2001-10-05 Paul Eggert <eggert@twinsun.com>
9629 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9630 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9631 build of $(TESTSUITE).
9633 2001-10-05 Akim Demaille <akim@epita.fr>
9635 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

9672 compatibility with POSIX shells.

9701 Don't use nested parenthesization. This patch was originally

9710 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9711 Check for `expr' arithmetic overflow, and for compilation failure,
9712 and invoke a new argument $4 if either is discovered.
9713 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9714 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9716 2001-09-28 Akim Demaille <akim@epita.fr>

9743 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
9744 * tests/c.at (Extensions, C keywords)
9745 (Broken/missing compilers, AC_PROG_CPP with warnings)
9746 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
9747 (AC_PROG_CPP requires AC_PROG_CC): here and...
9748 * tests/fortran.at (GNU Fortran 77): there.
9749 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9750 AC_TRY_RUN is about compilation, not shell commands.
9751 (Test Programs): AC_TRY_RUN works as used to be advertised.
9753 2001-09-27 Akim Demaille <akim@epita.fr>
9755 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9756 Raja R Harinath:
9757 Be sure to detect when $LINENO always returns the same value.
9758 Look for the original script, basename($0) is certainly not
9759 enough.
9760 Pass the CLI arguments to `$as_me.lineno'.
9762 2001-09-25 Akim Demaille <akim@epita.fr>
9764 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
9765 Be sure the close and reopen the LOG fd before and after using tee

9855 * tests/Makefile.am (package.m4): Remove.
9857 2001-09-22 Akim Demaille <akim@epita.fr>
9859 Rely on `$LINENO' when possible instead of `__oline__'.
9861 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
9862 `$LINENO' support replacement when not supported.
9863 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
9864 them explicitly to be sure they are not output before this section
9865 (via m4_require). Cosmetic only.
9866 * lib/autoconf/c.m4, lib/autoconf/general.m4,
9867 * lib/autoconf/programs.m4: Replace all the occurrences of

9871 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
9873 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
9874 character (u: -> ue) in a code comment.

9876 it works.
9878 2001-09-21 Akim Demaille <akim@epita.fr>
9880 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9881 Suggested by Jim Meyering.
9883 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9898 PATH_SEPARATOR.
9899 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9900 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9901 be used instead of ':'.
9902 * lib/autotest/general.m4: Replace occurrences of ':' in
9903 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9905 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9908 arguments. Fixed a typo.
9910 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9912 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9913 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9915 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9917 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

9926 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9927 already have $file). Set output files to binary mode (helps avoid
9928 CR issues on DOSish systems).
9930 2001-09-19 Akim Demaille <akim@epita.fr>
9932 * lib/autotest/general.m4: Englishoes.
9933 From Tim Van Holder and Alexey Mahotkin.
9935 2001-09-18 Paul Eggert <eggert@twinsun.com>
9937 * doc/autoconf.texi (Common Shell Constructs): New node,
9938 documenting AS_DIRNAME.
9939 (Limitations of Usual Tools): Refer to it when discussing dirname.
9940 Also, update discussion of POSIX standard to reflect latest draft.
9942 * lib/autoconf/c.m4:
9943 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9945 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9946 Do not pass a first argument with leading '-'
9947 to expr, by parenthesizing initial integers that might be negative.
9949 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9950 now merely checks whether it is an error to pass an argument
9951 to getpgrp.
9953 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9954 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9955 whether it is a (compile-time) error to pass an argument to
9956 getpgrp. This simpler test supports the revised documentation,
9957 and is all that AC_FUNC_GETPGRP's users really need.
9959 2001-09-18 Akim Demaille <akim@epita.fr>
9961 * doc/autoconf.texi (Limitations of Make) <$<>: New.

9969 2001-09-18 Paul Wagland <paul@wagland.net>
9971 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9972 correctly.
9973 Add test for AS_BASENAME.
9974 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9975 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9976 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9977 * tests/base.at: Fixed the expected responses. The old ones were
9978 one line out...
9979 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9980 the documentation claims it should (and how it behaved in 2.13).
9982 2001-09-18 Akim Demaille <akim@epita.fr>
9984 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9985 the AC_CONFIG_COMMANDS invocation.
9986 This also solves the name clash problems.
9987 Don't set the package's ID.
9988 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9989 No longer to be shipped.
9990 (version.in): Remove.
9991 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9992 * lib/autoconf/status.m4: Adjust.
9993 Use `m4_PACKAGE_STRING'.
9994 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9995 the only optional argument is the name of the test suite.
9996 Expect `package.m4' to define the package signature.
9997 * lib/autom4te.in (Autotest): Add `package.m4?'.
9998 * tests/Makefile.am (package.m4): New.
9999 * tests/suite.at: ifnames is a victim.
10001 2001-09-18 Akim Demaille <akim@epita.fr>
10003 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10004 AC_LIBSOURCE, AC_CONFIG_FILES.
10005 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10006 program version string doesn't match the package's.
10007 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10008 after `(cached)'.

10012 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10013 Allow expression to return any value that can fit into unsigned long
10014 (not int, as before). Check for output errors.
10016 2001-09-17 Bruno Haible <haible@ilog.fr>
10018 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10019 Always include <stdio.h> and <stdlib.h>. Evaluate
10020 the expression in an extra function before these includes. Call
10021 fprintf "%d" only after ensuring the argument is of type 'int'.
10022 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10024 2001-09-17 Paul Eggert <eggert@twinsun.com>
10026 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10027 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10028 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10029 when they don't exist.
10031 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10032 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10033 need it.
10035 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10036 version with the version used by fileutils 4.1, except use
10037 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10038 we don't need it.
10040 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10042 2001-09-13 Akim Demaille <akim@epita.fr>
10044 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10045 _first_.
10046 Reported by Gerrit P. Haase.
10048 2001-09-13 Akim Demaille <akim@epita.fr>
10050 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

10074 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
10076 2001-09-13 Akim Demaille <akim@epita.fr>
10078 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
10080 2001-09-13 Akim Demaille <akim@epita.fr>
10082 * lib/autotest/general.m4 (AT_INIT): Create and remove
10083 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10084 test suites can cohabit.
10086 2001-09-13 Akim Demaille <akim@epita.fr>
10088 * tests/mktests.sh: Don't output banners for empty test files.
10090 2001-09-13 Akim Demaille <akim@epita.fr>

10156 2001-09-07 Akim Demaille <akim@epita.fr>
10158 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
10159 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
10160 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
10161 related variables into `at_package_*'.

10173 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,

10187 to avoid GCC warnings.
10188 From Uwe Seimet.
10190 2001-09-05 Akim Demaille <akim@epita.fr>
10192 * bin/autom4te.in: --language is -l, not -s.
10194 2001-09-05 Akim Demaille <akim@epita.fr>
10196 Be ready to handle filenames as stupid as `dnl.at', for if even
10197 the maintainer is dumb enough to do that...
10199 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10200 excellence in M4 quotation: consider `__file__' is active.

10233 New, extracted from main.
10234 Use IO::File wherever possible.

10237 Don't invoke `_au_disable', since ac was not loaded, but just

10240 2001-08-31 Akim Demaille <akim@epita.fr>

10263 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
10265 2001-08-31 Akim Demaille <akim@epita.fr>
10267 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10268 (testsuite Scripts): There is no such thing as `atconfig.in'.
10269 And actually one diagram is missing: test suite runtime.
10271 2001-08-31 Akim Demaille <akim@epita.fr>
10273 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10274 inverse order.
10276 2001-08-31 Akim Demaille <akim@epita.fr>
10278 * bin/autoupdate.in (@include): `installcheck' revealed the path
10279 to m4sugar was lacking!
10281 2001-08-31 Akim Demaille <akim@epita.fr>
10283 * man/Makefile.am (.x.1): We really have to pass
10284 autom4te_perllibdir.
10286 2001-08-31 Akim Demaille <akim@epita.fr>
10288 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
10289 debug scripts, in particular passing explicitly listed tests to
10290 run is stupid.
10292 2001-08-31 Akim Demaille <akim@epita.fr>
10294 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10295 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10296 Use directly autom4te, not autoconf.
10297 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
10299 2001-08-31 Akim Demaille <akim@epita.fr>
10301 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
10302 * bin/autoheader.in (%symbol): Strip arguments of macros.
10304 2001-08-31 Akim Demaille <akim@epita.fr>
10306 * doc/autoconf.texi: Catch up -I, --include changes.
10308 2001-08-31 Akim Demaille <akim@epita.fr>
10310 * bin/autom4te.in (&parse_args): Die on unknown languages.
10311 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
10312 need for autoconf.
10313 Promote --include over --macrodir and other obsolete options.
10315 2001-08-31 Akim Demaille <akim@epita.fr>
10317 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
10318 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
10319 * bin/autom4te.in ($autoconf): Pass --force.
10320 `print $out' doesn't print `$_' but `$out'.
10321 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10322 (autoheader): Pass --force since the test suite goes too fast for
10323 the time stamps.
10324 Adjust to the new autoheader messages.
10326 2001-08-31 Akim Demaille <akim@epita.fr>
10328 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
10329 Check the completeness of the #template.
10330 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
10331 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
10332 invocation.
10334 2001-08-31 Akim Demaille <akim@epita.fr>
10336 * lib/Autom4te/General.pm (&find_file, &update_file): New.
10337 * bin/autoupdate.in, bin/autoheader.in: Adjust.
10338 Drop AC_MACRODIR dead for real.
10339 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10340 `autoheader: `config.hin' is created'.
10341 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10343 2001-08-31 Akim Demaille <akim@epita.fr>
10345 * bin/autoheader.in: Rewrite in Perl.
10346 * tests/autoheader: Adjust.
10348 2001-08-31 Akim Demaille <akim@epita.fr>
10350 * bin/autoconf.in (--include, -I): New option.
10351 Map --localdir, --autoconf-dir onto it.
10352 Forward autom4te's options instead of interpreting them.
10353 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10354 There is no such envvar since the inception of autom4te.cfg.
10355 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10356 * bin/autoupdate.in: Adjust, and perform more control.
10357 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
10358 * tests/autoconf: Dittowise.
10360 2001-08-31 Akim Demaille <akim@epita.fr>
10362 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10363 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10364 optionally `FILE'.
10365 Use -e, not -f, since /dev/null for instance is OK.
10366 (&parse_args): Adjust.
10367 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10369 2001-08-31 Akim Demaille <akim@epita.fr>
10371 * configure.ac: Also find tested executables in bin.
10372 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10373 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10374 installed peer executables, only PATH is allowed to resolve it.
10375 Pass `autoconf_dir' via options, not via invisible envvars.
10376 * lib/Autom4te/General.pm (&find_peer): Remove.
10377 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10378 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10379 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10380 find the executables for it.
10381 * tests/Makefile.am: Major cleanup. Too lazy to document...
10382 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10383 We only need PERL.
10384 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10385 indeed related to running the test suite, while passing
10386 --autoconf-dir and others is related to running non installed
10387 Autoconf executables. So don't do that, leave it to...
10388 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10389 * tests/autoscan: New.
10390 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10391 refer to library files: rely on --language.
10393 2001-08-29 Akim Demaille <akim@epita.fr>
10395 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
10396 s/--set/--language/.
10398 2001-08-29 Akim Demaille <akim@epita.fr>
10400 * doc/autoconf.texi: Strip the @nodes.
10401 Suggested by Paul Eggert.
10402 (Initializing configure): Typo.
10404 2001-08-29 Akim Demaille <akim@epita.fr>
10406 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10407 Suggested by Paul Eggert.
10409 2001-08-29 Akim Demaille <akim@epita.fr>
10411 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10412 download in a tmp dir.
10414 2001-08-29 Akim Demaille <akim@epita.fr>
10416 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10417 case insensitive OSes out there :(
10418 From Tim Van Holder.
10420 2001-08-29 Akim Demaille <akim@epita.fr>
10422 * lib/autom4te.in: New.
10423 * lib/Makefile.am (edit, autom4te.cfg): New.
10424 * bin/autom4te.in (BEGIN): Simplify.
10425 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
10426 (&load_configuration): New. Use it.
10427 (&parse_args): Support --mode, --set, and --melt.
10428 * bin/autoconf.in: Simplify and adjust.
10429 * tests/Makefile.am (AUTOMAKE): Use --set.
10430 * tests/atlocal.in: Adjust.
10431 * BUGS: distcheck and check are weak.
10433 2001-08-29 Akim Demaille <akim@epita.fr>
10435 * lib/autotest/general.m4: Use
10436 foo=`(command) 2>/dev/null`
10437 not
10438 foo=`command` 2>/dev/null
10439 (at-devnull): Rename as...
10440 (AT-devnull): this.
10441 (--clean): Remove AT-* files too.
10442 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10443 Reported by Nicolas Joly.
10445 2001-08-28 Akim Demaille <akim@epita.fr>
10447 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
10448 quotes inside single quotes.
10449 Reported by Nicolas Joly.
10451 2001-08-28 Kevin Ryde <user42@zip.com.au>
10453 * doc/autoconf.texi (Function Portability): Mention C right shifts.
10455 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
10457 * lib/autotest/general.m4: Reword some messages.
10458 (AT_INIT): Check for the `times' builtin before using it.
10459 Support test ranges as arguments to the testsuite.
10460 Have -e imply -d as the help text suggested.
10462 2001-08-27 Akim Demaille <akim@epita.fr>
10464 * Makefile.maint: Formatting changes.
10465 (do-po-update, po-update, cvs-update, update): New targets.

10468 2001-08-27 Akim Demaille <akim@epita.fr>
10470 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

10473 <AUTOTEST_PATH>: May contain absolute dir names.
10475 2001-08-27 Akim Demaille <akim@epita.fr>
10477 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10478 Support `VAR=VAL' as arguments.
10479 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
10480 may be set via the command line.
10482 2001-08-27 Akim Demaille <akim@epita.fr>
10484 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
10485 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
10486 first the build dirs, then the src dirs.

10489 2001-08-27 Akim Demaille <akim@epita.fr>
10491 * lib/autotest/general.m4 (AT_INIT): Output the definition of
10492 at_data_files earlier.
10493 (--clean, -c): New option.
10494 * tests/Makefile.am: Use this option.
10496 2001-08-27 Akim Demaille <akim@epita.fr>
10498 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
10499 `ac_top_builddir' to mimic Automake's vocabulary, which much more
10500 readable.
10501 Adjust callers.
10502 * doc/autoconf.texi (Configuration Actions): Document the vars
10503 available in commands.
10504 Emphasize the risks of collisions in init-cmds.

10508 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
10509 (Initializing configure): this new node.
10511 2001-08-27 Akim Demaille <akim@epita.fr>
10513 * Makefile.am (EXTRA_DIST): INSTALL.txt is a dead hack.

10524 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

10527 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)
10528 (_AH_VERBATIM_OLD, AH_TEMPLATE, _AH_TEMPLATE_OLD, AH_TOP, AH_BOTTOM):
10529 Move to...

10532 2001-08-27 Akim Demaille <akim@epita.fr>
10534 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
10535 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
10536 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
10537 -> ac_dir).
10538 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
10539 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
10541 2001-08-27 Akim Demaille <akim@epita.fr>
10543 * lib/autoconf/autoconf.m4 (AC_CONFIG_COMMANDS)

10566 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
10567 (AMTAR): Help automake define it.
10568 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
10569 needed, 1.5 can have a macro and a target with the same name.

10571 * m4/strip.m4: New.

10584 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
10585 Adjust callers.
10586 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10587 the name of the directory they're in, instead of the filename,
10588 since version.m4 is now in m4sugar, but m4_acversion must not be
10589 classified as an Autoconf macro.
10590 ($input_m4): Don't qualify the path to m4sugar.
10591 Rather, pass autoconf_dir to m4.
10592 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
10593 * tests/suite.at: Require 2.52c.
10595 2001-08-27 Akim Demaille <akim@epita.fr>

10607 of config.log on traps.
10608 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
10609 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
10610 for config.status'.
10611 Open the log as soon as possible.
10612 Use the same log introduction as configure's.
10614 2001-08-22 Paul Eggert <eggert@twinsun.com>
10616 * doc/autoconf.texi (Indices): New node.
10617 Move indices out of the top level menu and into this submenu.
10619 2001-08-22 Akim Demaille <akim@epita.fr>
10621 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10622 AC_TRY_COMMAND.
10623 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.

10664 * configure.ac (AT_CONFIG): Fix the path.
10665 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
10666 can be used.
10668 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
10670 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
10671 program with AC_LANG_PROGRAM before feeding it to
10672 AC_COMPILE_IFELSE. Cleanup grep usage.
10674 2001-08-20 Akim Demaille <akim@epita.fr>
10676 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
10677 * NEWS, README, README-alpha, TODO, tests/README: This package is
10678 `Autoconf', not `autoconf' (the executable).
10680 2001-08-20 Akim Demaille <akim@epita.fr>
10682 Info readers seem to need `Index' in the index node title :(
10684 * doc/autoconf.texi: Reverse the 2001-08-15 change which
10685 simplified index node names.
10687 2001-08-20 Akim Demaille <akim@epita.fr>
10689 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
10690 arguments are not literals.
10691 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
10692 Specify the output variables, and macros defined.
10694 2001-08-20 Akim Demaille <akim@epita.fr>
10696 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
10697 (Examining Syntax) <AC_TRY_COMPILE>

10798 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

10816 * doc/autoconf.texi: Work around Texinfo buglets.
10817 (Transformation Rules): One example is enough, users are expected
10818 to have their brains on. And BTW, use DESTDIR.
10819 (dvar): New macro. Use it.
10821 2001-08-17 Akim Demaille <akim@epita.fr>
10823 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

10863 value.

10871 (cvs-dist): depends upon it.
10873 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
10875 * tests/Makefile.am: Use a clean-local rule to remove
10876 autom4te.cache (it's a directory, not a file.
10877 * Makefile.am: Ditto (but maintainer-clean-local).
10879 2001-08-15 Akim Demaille <akim@epita.fr>
10881 * bin/autom4te.in (@m4_warning): New.
10882 (&handle_m4): Use it.
10883 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10884 warnings are issued at each run.
10885 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10886 is in the src tree.
10888 2001-08-15 Akim Demaille <akim@epita.fr>
10890 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
10891 don't waste time running `autoupdate --version' works.
10892 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10894 2001-08-13 Akim Demaille <akim@epita.fr>
10896 * doc/autoconf.texi (ma): Rename this index as...

10953 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10955 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10956 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10957 * doc/autoconf.texi (C Compiler Characteristics): Update
10958 documentation for AC_C_BIGENDIAN.
10960 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10962 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10963 magic values from an object file when cross-compiling.
10964 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10966 2001-08-10 Akim Demaille <akim@epita.fr>
10968 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10969 effects.
10970 Suggested by Russ Allbery.
10972 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10974 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10975 current $prefix to the sub-configures.
10977 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10979 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10980 extension (needed on BeOS). Reported by Guido van Rossum.
10982 2001-08-09 Akim Demaille <akim@epita.fr>
10984 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10986 2001-08-07 Akim Demaille <akim@epita.fr>
10988 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10989 removed.
10990 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10991 No need to remove the files before and after the each test, before
10992 each test and at the end of the suite is enough.
10993 Display only the children `times', not the shell's.
10994 If the test failed or was skipped, at-times is not available.
10996 2001-08-07 Akim Demaille <akim@epita.fr>
10998 Always produce testsuite.log, including when there are no
10999 failures. This helps getting information on skipped tests, and
11000 duration of the tests. Err, implement the latter btw.
11002 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11003 Dump information on the first run of each test.
11004 (AT_CLEANUP): Create `at-times' containing the duration of the
11005 test group.
11007 2001-08-07 Akim Demaille <akim@epita.fr>
11009 The use of `dumpstat' revealed that `len' was used although it
11010 should not. m4_text_wrap was using it, but in the Autoconf world
11011 where it is legal. Hence (i) test M4sh in its own world, not
11012 Autoconf's, and (ii), ahem, fix the bug :)
11014 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11015 does not like `' instead of [].
11016 (AT_INIT): Forbid `^_?AT_'.
11017 And don't output such tokens.
11018 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11019 `script.as', and `autom4te.cache'.
11020 Remove `empty' and `macro' which are no longer used.
11021 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11022 * tests/m4sugar.at: Use it.
11023 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11025 2001-08-07 Akim Demaille <akim@epita.fr>
11027 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11029 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11031 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11033 2001-08-04 Akim Demaille <akim@epita.fr>
11035 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11036 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11037 AC_TRY_LINK.
11038 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11039 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11040 (AC_F77_MAIN): Likewise.
11042 2001-08-04 Akim Demaille <akim@epita.fr>
11044 Don't rely on M4sugar outputting the patterns in files, since we
11045 might process the output _without_ running m4, hence without these
11046 files.
11048 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11049 * bin/autom4te.in (@Request::includes): Remove, unused.
11050 (@Request::source): Rename as...
11051 (@Request::input): this.
11052 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11053 (&handle_output): Fetch the patterns from the traces.
11054 `$forbidden' and `$allowed' are constant: use m//o.
11055 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11056 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11058 2001-08-04 Akim Demaille <akim@epita.fr>
11060 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11061 autoconf', i.e., in addition to caching traces, cache the output.
11063 * bin/autom4te.in (Request::cache): Rename as...
11064 (Request::id): this.
11065 ($cache, $icache, $tcache, $ocache): New.
11066 (&handle_m4): Save M4 output in the cache instead of $tmp.
11067 (&handle_output): Adjust.
11068 (&up_to_date_p): Check that the output cache is up to date too.
11069 (top level): Run `&handle_m4' iff force or the cache is invalid.
11070 Run `&handle_output' if the output cache is more recent.
11072 2001-08-04 Akim Demaille <akim@epita.fr>
11074 * bin/autom4te.in ($force): New.
11075 (&parse_args, &print_usage): -f, --force is a new option.
11076 (&handle_output): CPP directives might have spaces after `#'.
11077 (&parse_args): The first file only can be frozen.
11079 2001-08-04 Akim Demaille <akim@epita.fr>
11081 Don't let autom4te compute the `include' traces several times:
11082 first check that the trace cache file is up to date, and then
11083 compare its timestamp with that of the output.
11085 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11086 the preamble. Don't require 5.005 as Autom4te::General does it,
11087 and better yet (use `use', not `require'!).
11088 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11089 Class::Struct as Autom4te::Struct.
11090 * lib/Autom4te/General.pm (File::stat): Use it.
11091 (&mtime): New, export it.
11092 * bin/autom4te.in: Use it.
11093 Declare `$req' is invalid if it is outdated.
11094 Don't declare it valid before saving it if something went wrong.
11096 2001-08-04 Akim Demaille <akim@epita.fr>
11098 Autom4te shall not encode Autoconf data, and preselecting traces
11099 must be proposed to the users.
11101 * bin/autom4te.in (@required_trace): Remove.
11102 (@preselect): New.
11103 (&parse_args, &print_usage): -p, --preselect is a new option.
11104 (&up_to_date_p): Adjust.
11105 * bin/autoconf.in: Preselect some Autoconf macros.
11107 2001-08-04 Akim Demaille <akim@epita.fr>
11109 * tests/tools.at (autoconf --trace: user macros): Check traces on
11110 macros invoked without arguments, and macros invoked with multiple
11111 lines arguments.
11113 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11115 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11116 arguments.
11118 2001-08-03 Akim Demaille <akim@epita.fr>
11120 * bin/autoconf.in ($@): Work around the usual sh bug.
11121 From Nicolas Joly.
11123 2001-08-03 Akim Demaille <akim@epita.fr>
11125 Clean up the handling of the M4 builtins tracing exception.
11127 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11128 trace requests.

11130 (@m4_builtin): this.
11131 (%m4_builtin_alternate_name): New.
11132 (&parse_args): Complete the trace requests with alternate names.
11133 (&handle_traces): Hence no longer do it here.
11134 (&trace_requests): Remove, unused.
11136 2001-08-03 Akim Demaille <akim@epita.fr>
11138 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11139 m4_if, and m4_wrap.
11141 2001-08-03 Akim Demaille <akim@epita.fr>
11143 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11144 (m4_divert_pop): Dump the whole diversion stack when a diversion
11145 mismatch happens.
11146 * bin/autom4te.in (&handle_output): Remember of the first
11147 occurrence of a possibly undefined macro, not the last.
11148 Complain about the possibly undefined macros in the same order as
11149 the appear in the output.
11150 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11151 * tests/tools.at (autoconf: forbidden tokens, basic)
11152 (autoconf: forbidden tokens, exceptions): No longer sort
11153 autoconf's stderr, as it is now deterministic.
11154 Check that `dnl' is caught.
11156 2001-08-01 Akim Demaille <akim@epita.fr>
11158 * configure.ac: Bump to 2.52c.
11160 2001-08-01 Akim Demaille <akim@epita.fr>
11162 Version 2.52b.

11570 compiler, not the preprocessor.
11571 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

11573 the right thing.
11574 * Makefile.am (.m4.m4f): Emphasize M4 error messages and fail
11575 earlier if there are.
11577 2001-07-03 Akim Demaille <akim@epita.fr>
11579 * autoscan.in ($initfile): Remove.

11606 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
11607 dummy alternate main is required even if the user provides her own
11608 'main'.
11609 (AC_F77_MAIN): New macro to detect whether it is possible to
11610 provide an alternate 'main' function name, using the 'main' from
11611 the Fortran libraries.
11612 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
11613 cross-language link tests can be performed successfully.
11614 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
11615 after $LIBS, for consistency; this should be the general rule since
11616 the user may want to link to Fortran libraries that require $FLIBS.
11617 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
11619 2001-06-29 Pavel Roskin <proski@gnu.org>
11621 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
