4 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
5 for the existence of the directory at configure-time. That's

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

407 * doc/autoconf.texi: Be more consistent about using @acronym with
408 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
409 quite right (it talked about "OSF/Tru64", even though the
410 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
411 and it even mentioned "OSF 4"!) and at this point there's little
412 reason to talk about OSF any more, since it died in 1994.

429 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
430 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
431 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
432 (which belong to Xt, not X itself). See Debian bug 327655.

488 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
490 * bin/autom4te.in (handle_output): Do not forbid the empty
492 * tests/tools.at (autoconf: the empty token): New test.
494 2006-06-20 Stepan Kasal <kasal@ucw.cz>
496 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
497 calls, so that we do not care whether they are LIFO or FIFO;
498 in the m4_wrap, do not check which diversion is the topmost
499 one, just check that the stack is balanced at the end.
500 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
501 base diversion forever--pop the previous diversion before
502 opening the new one; consequently, remove the m4_wrap call.
503 * lib/autotest/general.m4 (AT_INIT): Likewise.
504 * tests/m4sugar.at: Do not use
505 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
507 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
508 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
510 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
511 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
512 Rework example of m4wrap token-pasting trouble so that it doesn't
513 care whether it's LIFO or FIFO.
514 Fix some "contrary to"s that are awkward in English.
516 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
518 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
519 to `yes' instead of `int$1_t' if the type is found, for more
520 consistent configure output (where $1 is the number of bits).
521 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
522 Suggested by Bruno Haible.
524 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
525 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
526 with system headers. Report by Bruno Haible.
528 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
530 * config/config.guess, config/config.sub: Sync from upstream.
532 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
533 in order to avoid picking up an older installed frozen m4sh.m4f.
534 Besides an outdated shell startup, this could have been created
535 by an earlier M4 version with incompatible frozen file format.
537 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
539 * README: Recommend m4 1.4.4 instead of 1.4.3..
540 * doc/autoconf.texi: Likewise.
541 (Special Chars in Names): Say that $(.FOO) is portable, as
542 suggested by Stepan Kasal.
543 (Installation Directory Variables, Build Directories):
544 (Automatic Remaking, Subdirectories, Fortran Compiler):
545 (Making testsuite Scripts, Defining Directories):
546 Quote variable usages better.
547 (Making testsuite Scripts): Add clean-local rule to makefile
548 snippet, by Eric Blake.
549 (Installation Directory Variables): Fix table item font.
550 Reword slightly to clarify. Generalize advice about
551 not using special characters to include all file-related
552 vars, not just VPATH.
553 (Special Chars in Variables): Warn about special characters in
555 (Assignments): Clarify default-value example as suggested by
557 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
558 (Special Shell Variables): Note leading ./ or ../, as suggested
560 (Limitations of Builtins): Under cd, warn about CDPATH.
561 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
564 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
566 * doc/autoconf.texi (Configuration Actions): Remove duplicate
567 `@var', for texi2html.
568 (Systemology): Some more word wrapping, for DVI output.
569 (autom4te Invocation): The short option for `--melt' is `-M',
572 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
574 * doc/autoconf.texi: More formatting and English tweaks,
575 many suggested by Ralf Wildenhues.
576 Reword to avoid "@code{...}'s" and the like, since it's ugly
577 with Emacs info mode. discontents -> woes.
578 Put a few "will"s back. time stamp -> timestamp.
579 side-effect -> side effect.
581 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
583 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
584 Warn about $@ not persisting. Problem reported by Julien Danjou in
585 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
586 (Special Chars in Names): Renamed from Leading _ in Macro Names.
587 Mention other special chars, too.
589 2006-06-14 Eric Blake <ebb9@byu.net>
591 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
593 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
595 * doc/autoconf.texi: Some systematic minor improvements, as
596 follows. Use "makefile" when talking about makefiles
597 generally (which might be named "makefile" or "Makefile" or even
598 "foo.mk"), "Makefile" when talking about a specific makefile
599 called "Makefile". This unclutters the text from weird quotes
600 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
601 values" rather than "@var{foo}s" and similar constructs containing
602 "}s". Use "Make rules" rather than "Makefile rules". Minor
603 English-language improvements. Change the prefix "sub-" to "sub"
605 Put blank lines around examples more consistently.
606 Avoid "rather" and "very" as intensifiers.
607 Avoid "will" as an auxiliary.
608 (Limitations of Make): Split this node into....
609 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
610 (Leading _ in Macro Names, Backslash-Newline-Newline):
611 (Backslash-Newline Comments, Long Lines in Makefiles):
612 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
613 (obj/ and Make, make -k Status, VPATH and Make):
614 (VPATH and Double-colon, $< in Explicit Rules):
615 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
616 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
617 New nodes, resulting from splitup of Limitations of Make.
618 All cross-references changed. Raise the top node from
619 a section to a chapter, and all subnodes accordingly.
620 Redo the introductory wording to match the new organization.
621 (Installation Directory Variables): Use an example that is
622 closer to what Autoconf actually does. Mention that VPATH's
623 value should not contain metacharacters or white space.
624 (Fortran Compiler): Fix a VPATH bug in an example.
625 (Leading _ in Macro Names): Mention that this problem is no longer
626 of practical concern.
627 (VPATH and Make): Reword the advice to make it clearer
628 that Autoconf and Automake support VPATH in non-GNU make, but
629 many packages have bugs in this area.
630 ($< in Explicit Rules): Refer to Build Directories rather
631 than using a (non-VPATH-safe) example.
632 (Automatic Rule Rewriting): Mention the sort of disaster that
633 can ensue with Solaris-style rule rewriting with VPATH.
635 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
637 * doc/install.texi (Compilers and Options): Weaken the
638 suggestion to use GNU make for VPATH builds.
640 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
641 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
643 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
644 in regular expression.
646 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
648 * doc/autoconf.texi (Installation Directory Variables):
649 Drop extra @samp from `@table @samp' item.
650 (Limitations of Usual Tools): Comment fix.
651 Do not nest @samp just to point to other table items.
652 (Writing testsuite.at) <AT_CHECK>: The second argument to
653 `@dvar' is already @samp'ed.
654 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
655 do not use @var in the second argument.
657 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
659 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
660 $as_shell.exe too. Problem reported by Andreas Buening in
661 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
663 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
665 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
666 `unused variable' compiler warning, for `-Wall -Werror'.
667 Reported by Jaap Haitsma in
668 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
670 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
672 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
673 case the compiler dumps core. Problem reported for
674 OpenServer 5.0.7 by Tim Rice in
675 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
676 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
679 2006-06-06 Tim Rice <tim@multitalents.net>.
681 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
682 "ERROR" only shows up in "make check" output if there is an
685 2006-06-06 Eric Blake <ebb9@byu.net>
687 * tests/tools.at (automatically allowed tokens): Fix typo.
689 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
691 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
693 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
694 typically overflows on x86 CPUs, even though the C standard
697 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
699 * configure.ac (AC_INIT): Bump to 2.59e.

706 * config/texinfo.tex: Sync from upstream.
708 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
709 seen, invoke libtoolize with `--ltdl' argument.
710 * lib/autom4te.in (Autoreconf-preselections): Adjust.
712 Suggested by Eric Blake.
714 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
716 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
717 reported by Ralf Wildenhues.
718 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
720 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
724 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

730 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
731 message issued by AC_REQUIRE.
732 * tests/m4sugar.at: Check m4_require's error message.
733 * tests/base.at: Check AC_REQUIRE's error message.
734 * tests/local.at (AT_CHECK_M4): New macro, almost identical
736 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
738 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
739 `expout' as the last parameter.
740 * tests/tools.at: Adapt to the above change.
742 2006-06-04 Stepan Kasal <kasal@ucw.cz>
744 * doc/autoconf.texi (Limitations of Usual Tools): Correct
745 information about race-free implementations of mkdir.
747 2006-06-04 Eric Blake <ebb9@byu.net>
749 * bin/autoreconf.in (help): Document M4 environment variable.
750 * bin/autoconf.as (Usage): Likewise.
751 * bin/autom4te.in (help): Likewise.
752 * doc/autoconf.texi (autom4te Invocation): Likewise.
754 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
756 * NEWS: GNU make now recommended for VPATH builds.
757 Mention that some macros are now documented to be obsolescent.
759 Prefer "current" to "modern" to describe
760 currently-used (albeit perhaps old-fashioned) hosts.
761 Mention which ancient features no longer need to be worried about.
762 setgid -> set-group-ID
763 setuid -> set-user-ID (these are the Posix terms)
764 Fix some misuses of "only".
765 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
766 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
767 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

772 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
773 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
774 Mention that these macros are obsolescent.
775 (Installation Directory Variables): shall -> should
776 (File Descriptors): Mention that 0, 1, 2 might get reopened.
777 Mention that it's now safe to use 3 and 4.
778 (Limitations of Usual Tools): cp -r is now specified by Posix.
779 Omit longwinded and obsolescent discussion of cp -f.
780 Modernize discussion of expr, ls.
781 (Limitations of Make): Modernize discussion of VPATH builds.
782 Mention $? as a workaround in some cases.
783 * doc/install.texi (Basic Installation):
784 Mention "./configure; make; make install" first. Be more
785 specific about why this file is generic. Remove unnecessary
786 parens. Remove misleading "only". Remove obsolete advice
787 about csh. Don't say "configure" takes awhile; say it
788 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
789 and CC=c99 rather than CC=c89, as these are blessed by current
790 Posix. Recommend GNU make if doing a VPATH build.
792 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
794 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
795 examples involving shell prompts.
797 2006-06-02 Stepan Kasal <kasal@ucw.cz>
798 and Paul Eggert <eggert@cs.ucla.edu>
800 * doc/autoconf.texi (Here-Documents): Add details about the
801 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
802 use "here-documents" instead of "here documents".
804 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
806 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
808 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
810 * doc/autoconf.texi (File System Conventions): Warn about ":"
811 anywhere in directory names.
813 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
815 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
816 about quoting the case statement, just in case.
817 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
818 was fixed in ksh93g; reported by Ralf Wildenhues.
820 2006-05-31 Stepan Kasal <kasal@ucw.cz>
822 * doc/autoconf.texi (System Services): Do not document
823 overriding EXEEXT via ac_cv_exeext=ext.
824 (Particular Programs) <AC_PROG_MKDIR_P>:
825 Document that ${MKDIR_P} understands --.

832 argument with leading hyphen. Problem reported by Paul Eggert.
834 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
836 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
837 about quoting ac_try: quote all of it, if any of it seems suspicious.
838 This means we don't have to worry about ${ or sed any more.
839 Also, double-quote the case statement, to work around misuses via
840 underquoting as reported by Ralf Wildenhues in
841 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
842 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
843 undocumented and dangerous macro.
844 Problem reported by Ralf Wildenhues in

853 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
855 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
856 since evidently some packages rely on the old, broken behavior.
857 Problem reported by Ralf Wildenhues in
858 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
859 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
860 pre-2006-05-26 definitions, but leave in the comments that
861 these macros are dangerous and should not be used.
862 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
863 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
864 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
865 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
866 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
868 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
870 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
871 the use of 'tr', since this is our only use of 'tr'.
873 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
874 and Paul Eggert <eggert@cs.ucla.edu>
876 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
877 Don't assume 'grep' works on long lines, since AIX grep doesn't.
879 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
881 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
882 the output file in the `${datarootdir}' test.
884 2005-05-28 Stepan Kasal <kasal@ucw.cz>
885 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
887 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
888 mention of `datarootdir' in the input file(s), but literal
889 `${datarootdir}' in the output file, and we haven't warned yet,
890 then warn as well: the user may have (erroneously) used
891 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
892 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
893 * tests/torture.at (datarootdir workaround): Extend this test.
896 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
897 and Paul Eggert <eggert@cs.ucla.edu>
899 * doc/autoconf.texi (autoheader Invocation): The first argument to
900 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
901 alternatives and clear up the language a bit.
903 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
905 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
906 ac_config_guess, ac_config_sub, ac_configure.
907 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
908 Fix typo that prevented an unnecessary space from being removed.
909 Problems reported by Ralf Wildenhues in:
910 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
912 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
914 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
915 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
916 Don't use the term "thread-safe" to talk about mkdir race
917 conditions, since the problem is more a process than a thread
918 issue. Problem reported by Stepan Kasal in:
919 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
920 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
921 the test for 'install' more closely. Look at MKDIR_P first.
922 Look in the PATH, and at /opt/sfw/bin.
923 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
924 Don't bother to try mkdir -p, since we already check mkdir --version;
925 just look at the version number. (There's no easy way to check
926 for race-free implementations.)
927 * tests/tools.at (autoconf: subdirectories): Adjust to above
928 changes, since MKDIR_P now might end in "/mkdir -p".
930 * doc/autoconf.texi (autoheader Invocation): Mention that the
931 first arg of AC_DEFINE_UNQUOTED must be a literal.
932 Problem reported by Ben Pfaff in
933 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
935 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
936 * doc/autoconf.texi (Special Chars in Variables): New section.
937 (Preset Output Variables): Warn about special chars in CPPFLAGS.
938 (Installation Directory Variables): Quote $(datadir) better.
939 (Limitations of Builtins): Describe some of eval's trickiness.
941 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
942 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
943 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
944 in front of every arg, not just trailing args. Quote apostrophes.
945 (_AC_EVAL_ECHO): New macro.
946 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
947 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
949 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
950 exposed by quoting of eval argument. Put the command on line line
952 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
953 (_AC_PATH_X, AC_PATH_X): Quote more safely.
954 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
955 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
956 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
957 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
958 Use eval more safely.
959 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
960 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
962 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
963 lines, exposed by quoting of eval argument.
965 2006-05-26 Stepan Kasal <kasal@ucw.cz>
966 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
968 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
969 initialization of `ac_cv_exeext', do not override it if it was
970 already set, unless it was set to `no', for compatibility with
971 Autoconf-2.13, and comment this.
972 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
973 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
974 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
975 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
976 Document that this test may be overridden by setting
979 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
981 Revert these two patches:
983 2006-04-06 Eric Blake <ebb9@byu.net>
984 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
985 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
988 2006-04-01 Stepan Kasal <kasal@ucw.cz>
989 Clean up _AC_COMPILER_EXEEXT* macros.
990 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
991 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
992 ac_file to the name of the default output file and call
993 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
994 initial `rm' of the candidate files...
995 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
996 the same list in subsequent `rm' calls, and for the temporary
997 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
998 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
999 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1000 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1001 no longer needed) by libtool. Make it a cache check.
1002 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1003 copied here by mistake.
1004 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1005 _AC_COMPILER_EXEEXT.
1006 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1007 _AC_COMPILER_OBJEXT directly.
1008 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1010 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1012 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1013 Fix description of how the buggy `sed' works.
1015 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1019 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1020 ENOLCK. Only mention `make -j' when applicable. Only raise
1021 fatal errors when `make -j' is involved. Improve error message.
1023 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1025 * doc/autoconf.texi (Here-Documents): We now know more about
1026 the variable expansion in here documents bug.
1027 Thanks to Tim Rice and Stepan Kasal.
1029 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1030 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1032 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1034 * tests/autotest.at (Multiline command from M4 expansion):
1035 No failure to be expected if the shell quotes newlines in
1036 commands in the `set -x' output. Report by Tim Rice.
1039 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1041 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1042 expansion in the here-documents used by config.status, as that
1043 runs afoul of the Korn shell version M-12/28/93d bug described in
1044 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1045 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1046 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1048 2006-05-23 Jim Meyering <jim@meyering.net>
1050 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1051 Fix typo introduced with 2006-04-02 change. It reversed the sense
1054 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1056 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1057 ac_dB slightly, to save bytes in the script.
1058 Max out at 50 lines, rather than 96; this is more likely
1059 (though not guaranteed) to avoid obscure 'sed' failures.
1061 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1063 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1064 `tr -d -' as bad option argument. Work around this by deleting
1065 an unrelated character.
1066 Report by Tim Rice <tim@multitalents.net>.
1068 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1069 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1070 Stepan Kasal <kasal@ucw.cz>
1072 * doc/autoconf.texi (Particular Programs): Do not promise that
1073 we always prefer the GNU version of the program, and that we
1074 search according to PATH; both rules can have exceptions.
1075 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1076 AC_PROG_SED. Move descriptions of limitations
1077 to the Limitations of Usual Tools section.
1078 (Limitations of Usual Tools) <sed>: Mention script length
1079 limitations with Solaris /usr/ucb/sed.
1080 <grep>: Fix wording for empty alternative. Mention that -c and
1081 -l should not be combined, and that -E and -F should not be
1084 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1085 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1087 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1088 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1090 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1092 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1093 AC_DEFINE is now passed to m4_pattern_allow.
1094 * NEWS: Mention that; likewise for AC_SUBST.
1095 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1096 the parameter to m4_pattern_allow.
1097 * tests/tools.at: Add a check for that.
1099 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1101 * lib/autoconf/status.m4: Fix typos.
1103 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1105 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1106 only the files that this macro generates.
1108 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1110 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1111 the HP-UX sed limitation of 99 commands, labels do not count.
1112 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1114 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1116 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1118 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1119 Import the following fix from coreutils:
1121 2006-01-13 Jim Meyering <jim@meyering.net>
1123 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1124 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1125 not double-quote uses of that variable, to accommodate the rare
1126 case in which getmntent is available in none of the libraries
1127 checked. This happens at least on FreeBSD 5.0.
1129 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1131 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1132 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1133 some other programs unwisely rely on these undocumented vars.
1134 But put in warning comments about them.
1135 Problem reported by Ralf Wildenhues in
1136 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1137 * NEWS: Document that these variables are intended to go away.
1139 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1141 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1142 and set the language to C++ (analogous to the equivalent Fortran
1145 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1146 * doc/autoconf.texi (C++ Compiler): Document it.
1147 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1150 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1152 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1153 that caused config.status to generate 100-command sed scripts; the
1154 portable limit is 99.
1156 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1158 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1159 variable `ac_d' instead of `d' to avoid infringing namespace.
1160 Report by Ralf Menzel.
1162 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1164 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1165 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1166 * tests/tools.at (autoconf: subdirectories): New test, taken from
1167 the corresponding problem report by Ralf Wildenhues in:
1168 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1170 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1171 Quote some uses of shell variables if they might suffer unexpected
1172 globbing. This doesn't fix all instances of quoting problems that
1173 I found, just the easy ones that look safe.
1174 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1175 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1176 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1177 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1178 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1179 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
1180 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
1182 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
1183 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1185 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1187 * bin/autoreconf.in ($help): Reword according to the manual.
1188 Suggested by Olly Betts.
1190 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1191 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1193 * bin/autoreconf.in: Pass the directory argument to
1194 `require_configure_ac'. Fix comment.
1195 * tests/torture.at (Configuring subdirectories): Expose this.
1196 Reported by Olly Betts.
1198 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1200 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1201 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1202 Automake as follows:
1204 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1205 `$configure_in' instead of `configure.in', to preserve
1206 directory component.
1208 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1210 * config/config.guess, config/config.sub, config/texinfo.tex,
1211 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1213 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1215 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1216 test for C99 conformance; (bool) 0.5 is an integer constant
1217 expression, but (bool) -0.5 is not. Problem reported by Fedor
1218 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1220 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1222 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1223 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1224 Warn about obsolete install-sh files. Remove stray sentence
1225 fragment and fix cross reference.
1226 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1227 install -d; this undoes the 2006-05-10 change.
1228 (MKDIR_P): Mark with AN_MAKEVAR.
1229 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1230 that we don't require $INSTALL to be thread-safe. Move comments
1231 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1232 of AC_PROG_INSTALL. Output a message saying that we're checking
1233 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1234 MKDIR_P instead of AC_SUBST.
1235 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1236 Special magic for MKDIR_P, too.
1237 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1239 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1241 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1243 Sync from Automake, as follows:
1245 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1246 * config/install-sh: Initialize IFS, so field splitting isn't
1248 * config/mkinstalldirs: Likewise.
1249 * config/missing: Remove superfluous quotes. Replace all uses of
1250 `[' by `test', for consistency, and for..
1251 * config/missing (sed_minuso, sed_output): New variables.
1252 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1253 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1254 Fixes `missing' to detect `--output' for help2man. Fixes
1255 PR automake/483. Report by Dennis J. Linse.
1256 (autom4te): Document in `missing --help'.
1258 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1260 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1261 * config/install-sh: Don't use 'path' to talk about file names,
1262 as per GNU coding standards. Close a race condition reported by Ralf
1263 Wildenhues and Stepan Kasal. There is still a race condition
1264 on hosts that predate Posix 1003.1-1992, but we can't help this.
1265 Don't mishandle weird characters like space on pre-Posix hosts.
1266 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1267 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1268 AC_PROG_MKDIR_P from AS_MKDIR_P.
1269 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1270 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1271 earlier editions are not (including Automake 1.8.3).
1272 Do not suggest mkinstalldirs for thread-safety.
1273 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1274 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1275 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1276 presence of special characters and race conditions.
1277 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1278 in Autoconf's name space.
1280 2006-05-10 Bruno Haible <bruno@clisp.org>
1281 and Paul Eggert <eggert@cs.ucla.edu>
1283 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1284 from Automake with minor changes.
1285 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1287 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1289 * config/install-sh: Update to Automake CVS version, as follows:
1290 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1291 * lib/install-sh: Simplify the expr implementation of dirname.
1292 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1293 * lib/install-sh: Handle --, and diagnose unknown options.
1295 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1297 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1298 `./autom4te' to create `./testsuite', since the `all' target
1299 will ensure its presence, but `installcheck' should not create
1300 the uninstalled wrappers.
1302 * tests/torture.at (Unusual Automake input files): Skip if we
1303 detect automake < 1.8.
1305 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1307 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1308 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1309 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1312 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1314 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1315 munge (multiple) white space and other oddities.
1316 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1317 single quotes in variable assignment.
1318 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1319 and similar failures by adding multiple spaces, tabs, and other
1321 Report and different test suggested by Francesco Romani
1322 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1324 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1325 single quotes, we only need to search for single quotes; this
1326 both simplifies the search pattern, and makes us less
1327 susceptible to `echo' variations for arguments not containing
1329 (_AC_ARG_VAR_VALIDATE): Likewise.
1331 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1333 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1334 `$*' and IFS concatenation issue with traditional shells and
1335 bash-2.04. Report by Seanster@Seanster.com.
1337 2006-05-03 Bruno Haible <bruno@clisp.org>
1339 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1340 precisely which Mac OS X versions have the od problem.
1342 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1344 * doc/autoconf.texi: Use @option systematically.
1346 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1347 and Bruno Haible <bruno@clisp.org>
1349 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1351 (Integer Overflow): Mention the special case of integer division
1354 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1356 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1357 traditional shells like the Solaris one that do not use the
1358 first IFS character for assembling `$*'.
1359 Prompted by a related report from autoconf_bug@nro.ca.
1361 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1362 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1364 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1365 Mention more problems with the -e option.
1367 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1370 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1372 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1373 in URLs to improve DVI formatted output (requires texinfo 4.6).
1374 (System Services, Systemology, Shellology): Likewise.
1375 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1378 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1380 (Runtime): Fix macro argument names to match description:
1381 `action-if-found' -> `action-if-true' and similarly.
1382 (Obsolete Macros): Likewise.
1383 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1384 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1385 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1387 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1389 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1392 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1395 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1397 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
1398 /bin/sh set unsorted output.
1399 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
1400 * tests/local.at: Likewise.

1404 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1405 (Integer Overflow, Null Pointers, Buffer Overruns):
1406 (Floating Point Portability, Exiting Portably): New sections.
1407 (Writing Test Programs): Fix some langauge. Recommend exiting
1408 with status 1, not merely nonzero. Clarify exit declaration.
1409 (Run Time): Move C exit status stuff to new Exiting Portably section.
1410 (Systemology): Mention Posix and levenez. Update v7 reference.
1411 (Portable Shell): Mention the Posix shell.
1413 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1415 * bin/autoconf.as (me): Replace by as_me.
1417 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1419 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1420 since as_me isn't set yet.
1422 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1424 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1425 a few minor bugs in this area.
1427 * doc/autoconf.texi (Programming in M4sh): Comment out the
1428 documentation of AS_BASENAME, for now.
1429 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1430 (Limitations of Builtins) <basename>: Do not refer to
1432 * bin/autoconf.as (me): Don't use AS_BASENAME.
1433 (dir): Remove the unused variable.
1434 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1435 AS_DETECT_REQUIRED. All uses changed.
1436 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
1438 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1439 (AS_BASENAME): Use "basename --" to protect against leading "-".
1440 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1441 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1442 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1443 (_AS_DIRNAME_PREPARE): Likewise.
1444 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1445 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1446 (AS_DIRNAME): Use "dirname --".
1448 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1450 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1451 of "run time" and "run-time" changed to "runtime", for consistency.
1452 * lib/autoconf/fortran.m4: Likewise (in comment).
1453 * lib/autoconf/functions.m4: Likewise.
1454 * lib/autoconf/general.m4: Likewise.
1455 * lib/autoconf/headers.m4: Likewise.
1457 * doc/autoconf.texi (Run Time): Document the exit status situation
1458 with more accuracy and detail.
1460 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1462 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1463 Archive is not officially `GNU' any more. Update URL.
1464 (Defining Directories): Likewise
1465 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1467 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1469 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1470 newline from the `trap' code to finish `config.log'; the NetBSD
1471 /bin/sh resets the exit status after an empty command, as
1472 documented in doc/autoconf.texi.
1473 Reported by Dalibor Topic <robilad@kaffe.org>.
1475 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1477 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1478 Suggested by Bruno Haible.
1480 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1482 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1483 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1484 Instead, just list the shells that we know work.
1485 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1486 changed. Be more cautious about the _cv_ variable.
1487 * tests/tools.at (Syntax of the shell scripts): Check the
1488 _cv_ variable once, at first, to avoid an internal autoconf error
1489 when sh -n does not work.
1491 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1493 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1495 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1497 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1498 use ">&-" since we're only 99.999% sure that this is portable,
1499 and since the MinGW bug is fixed in a different way.
1500 * lib/autotest/general.m4 (AT_INIT): Likewise.
1502 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1504 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1505 before opening config.log, to avoid hitting a bug on MinGW.
1507 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1509 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1510 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1511 This works around a MinGW bug reported by Eric Paire.
1512 Make sure that all writes to the log file append to it,
1513 rather than possibly losing data.
1514 * lib/autotest/general.m4 (AT_INIT): Likewise.
1516 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1518 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1521 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1525 * configure.ac (AC_INIT): Bump to 2.59d.
1527 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1531 * Makefile.maint (news-date-check): Do not require a leading `*'
1532 before the release date in NEWS.
1534 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1535 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1537 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1538 the instantiated file do not contain the string 'datarootdir'
1539 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1540 @mandir@, replace the reference '${datarootdir}' by the value.
1541 * tests/torture.at (datarootdir workaround): New test.
1542 * NEWS: Advertise this temporary fixup.
1543 Based on a patch by Bruno Haible, reported and analyzed by
1544 Paul Eggert and Noah Misch.
1546 2006-04-12 Eric Blake <ebb9@byu.net>
1548 * tests/autotest.at (Debugging a failed test): Fix comment.
1550 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1552 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1553 all the changes since 2006-04-07.
1555 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1557 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1558 succeeded, but `ln -s file dir' failed, take care to remove the
1559 leftover target before the next test, to prevent its spurious
1560 failure; also make sure `ln file dir' works before selecting it.
1561 Thanks to Keith Marshall for pointing this out.
1564 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1565 assignments in `at_debug_args', so that we put them correctly
1566 in the `run' script.
1567 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1568 Reported by Eric Blake.
1570 2006-04-11 Eric Blake <ebb9@byu.net>
1572 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1573 top-level tests after micro-suite has been run. Used in...
1574 (Debugging a successful test, Debugging script and environment),
1575 (Debugging a failed test): ...these new tests. The first of these
1577 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1578 macro, split out from...
1579 (AT_INIT): ...here, so that using -d also generates a run script.
1580 Document that -d inhibits top-level logging.
1581 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1582 inhibits top-level logging; debug scripts are created.
1584 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1586 * tests/autotest.at (Empty test, Empty check): New test to check it.
1588 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1591 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1593 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1594 the files if a problem appears. Make the empty *.at files
1595 read-only, too. Proposed by Ralf Wildenhues.
1597 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1599 * config/Makefile.am: Add comment to force updated Makefile.in.
1601 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1602 space only patch to this file, this patch causes the Makefile.in
1603 files that include freeze.mk to be updated, and thus have a
1604 newer time stamp again, which in turn makes a pristine CVS
1605 checkout have correct time stamps.
1607 * Makefile.maint (cvs-sv): New macro, to be used..
1608 (config.guess-url_prefix, config.sub-url_prefix)
1609 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1610 point to CVS text checkout of Gnulib files.
1611 (copyright-check): Bump current year.
1612 (announcement): Do not hard-wire `./announce-gen'.
1613 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1615 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1617 (wget_files): Update config.guess, config.sub, texinfo.tex by
1618 `wget-update', now that their URLs work again.
1620 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1622 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1623 Problem noted by Paul D. Smith.
1625 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1627 * doc/autoconf.texi: Remove unused words from word list.
1628 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1629 .x-sc_trailing_space: New files.
1631 * doc/standards.texi: Sync from gnulib.
1633 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1634 `LIBOBJDIR' as experimental.
1636 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1637 with a target directory; it's internally implemented as `cp'
1638 anyway, but since Autoconf advertises the possibility to use
1639 a target directory when LN_S is `ln -s', we need to find out.
1640 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1641 analyzed by Keith Marshall <keith.marshall@total.com>.
1645 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1647 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1648 confdefs.h as-is. In general, if it has backslash-newline or the
1649 like, then it doesn't work either to sort or to remove empty
1652 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1654 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1656 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1658 * lib/autom4te.in (Automake-preselections): Preselect
1661 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1663 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1664 apostrophe within a single-quoted string, as this is the usual
1665 tradition and is easier to read than '"'"'. Don't rely on the
1666 shell treating "$/" like '$/'. Use a more-consistent indenting
1669 2006-04-09 Eric Blake <ebb9@byu.net>
1671 * tests/autotest.at (Backquote command substitution),
1672 (Multiline backquote command substitution): Remove mistaken
1673 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1675 (Parenthetical command substitution, Multiline parenthetical
1676 command substitution): here.
1678 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1680 Import macros from gnulib (often changing their name).

1709 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1710 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1711 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1712 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1713 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1714 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1715 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1716 (Coding Style). Don't mention m4_expand_once.

1737 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
1738 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
1740 2006-04-08 Stepan Kasal <kasal@ucw.cz>
1742 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1743 of the warning introduced by the 2001-08-28 change.
1745 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
1746 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1748 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
1749 variables shall be overriden by the cache.

1753 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1755 Revert the patch from 2006-04-01 and only improve
1756 _AS_DETECT_BETTER_SHELL:
1758 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1759 skip nonexistent directories.
1760 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1761 only shell candidates which exist.
1762 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1763 * lib/autotest/general.m4 (AT_INIT): No need to give three
1764 parameters to _AS_PATH_WALK.
1766 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1767 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1769 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1770 distinguish m4sugar macros.
1771 * tests/tools.at (autoupdating with aclocal and m4_include):
1772 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1773 test case by Noah Misch <noah@cs.caltech.edu>.
1775 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1777 Revert my change from 2006-03-17, in other words:
1778 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1780 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1781 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1784 2006-04-07 Eric Blake <ebb9@byu.net>
1786 * doc/autoconf.texi (Programming in M4sh): Document that
1787 AS_MKDIR_P exits the script on failure.
1788 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1790 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1792 * config/elisp-comp, config/install-sh, config/mdate-sh,
1793 config/missing, config/mkinstalldirs: Sync from Automake.

1808 Paul Eggert <eggert@cs.ucla.edu>,
1809 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1811 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1812 whether `set' quotes correctly: redirect stderr of the tested
1813 `set', and use a subshell, for Ultrix; use `sed' instead of
1814 `grep' for zsh `set' which may write binary output; match only
1815 at the beginning of a line, to avoid false positives.
1816 In order to avoid false positives by unrelated variables with
1817 multiline content, put the dump algorithm in a subshell and
1818 unset all variables containing newlines (except some which are
1819 special to the shell). Warn about cache variables that are
1822 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1824 * config/config.guess, config/config.sub, config/texinfo.tex:
1827 * tests/mktests.sh: Reword comments.
1829 * tests/mktests.sh: Only skip internal macros starting with

1833 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1834 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1835 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1836 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1838 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1839 shell issue with double-quoted command substitutions of native
1841 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
1844 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

1861 * tests/Makefile.am (maintainer-check-posix):
1862 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1864 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1865 ac_config_<foo>s again, sometimes normalized, sometimes not.
1866 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1867 (AC_CONFIG_COMMANDS): Do not do so here.
1868 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS

2812 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2813 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2814 by the function rather than ignoring it.
2815 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2816 comparing its address. Intel's interprocedural optimization was
2817 outsmarting the old heuristic. Problem reported by
2820 2005-10-19 Stepan Kasal <kasal@ucw.cz>
2822 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
2824 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
2826 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
2827 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
2829 2005-10-04 Stepan Kasal <kasal@ucw.cz>
2831 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
2832 before removing it (chmod -R u+rwx); there are three instances of this.
2834 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2835 Stepan Kasal <kasal@ucw.cz>
2837 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2838 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2839 make its content writable before removing it. Remove an errorneous
2840 comment from the end, where the logs of the failed tests are copied
2841 to the main log file.
2843 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2845 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
2846 in case the computer is too quick. Double quote the configure.ac
2849 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
2850 problems if the testsuite were running too fast.
2852 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2854 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2855 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2856 (which belong to Xt, not X itself). See Debian bug 327655.
2857 * NEWS: Mention this.
2859 2005-09-07 Stepan Kasal <kasal@ucw.cz>
2861 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
2863 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
2865 * config/move-if-change: Don't output "$2 is unchanged";
2866 suggested by Ben Elliston. Handle weird characters correctly.
2868 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2870 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2871 calls, so that the final expansion of this macro is shorter.
2872 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2873 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2874 the cleanup there. Use AS_VAR_* macros, to be more general.
2875 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2877 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2879 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2881 2005-09-01 Stepan Kasal <kasal@ucw.cz>
2883 * doc/autoconf.texi (Configuration Headers): Add an index entry
2886 2005-08-26 Pavel Roskin <proski@gnu.org>
2888 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
2889 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
2892 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2894 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2895 The previous patch didn't work, so try a better one.
2897 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2899 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2900 in the example. Reported by Bruno Haible.
2901 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2902 "if $undefined_var;" succeeds with my shell.
2904 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2905 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2906 but change the m4_divert_text to m4_divert_once.
2908 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2910 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2911 Work around bug in Solaris /usr/xpg4/bin/awk.
2912 The bug is present in at least Solaris 8 through 10.
2914 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2916 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2917 some evil values and relying on the fact that $* concatenates the
2918 parameters by the first character from IFS.
2920 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2921 Stepan Kasal <kasal@ucw.cz>
2923 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2924 first header appears, define AH_HEADER.
2925 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2926 Update limitations about when to call AC_CONFIG_HEADERS.
2927 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2928 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2929 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2930 ``Configuration Actions''; fix their index entries.
2932 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2933 options correctly. Process N-M as M-N if M is smaller than N.
2934 Process ranges correctly so that N-N will run only N.
2935 Sort and uniquify the tests that will be run. If there is more
2936 than one test, reinsert the banners for the tests.
2937 * tests/autotest.at (Keywords): Unmark XFAIL.
2939 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2941 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2942 before passing the macro name to AH_TEMPLATE.
2944 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2945 now opens log after option processing; in particular, --version
2946 and --help do not touch config.log.
2948 * Makefile.maint: Revert the change from 2005-08-12.
2950 2005-08-22 Stepan Kasal <kasal@ucw.cz>
2952 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
2954 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
2956 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2958 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2959 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2962 * doc/autoconf.texi (Defining Symbols, Changed Results):
2963 Prepend to LIBS, not append, in examples.
2965 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2967 When building in place, set srcdir="."; suggested by Tim Van Holder.
2969 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2970 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2971 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2972 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2973 does not mean "no --srcdir option".
2975 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2977 * tests/autoscan.at (autoscan): New file.
2978 * tests/suite.at: Use it.
2979 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
2980 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2982 * tests/autotest.at (Keywords): Test keywords combinations.
2984 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2986 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2987 add "2>&1"; gzip 1.2.4 prints help on stderr.
2989 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2991 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2992 was pushdef'ed twice while popped only once. Push it only once.
2993 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2995 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2997 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
2998 prefixed by mere "===", not "configure: === ".
3000 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
3002 * Makefile.maint: Update from Bison.
3004 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3005 "<tab>" in comment, so that the point is understandable.
3007 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3009 Rewrite substantial part of lib/autoconf/status.m4.
3010 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3011 and CONFIG_COMMANDS are not processed in four separate loops.
3012 Instead, there is one main loop. This alows that the common code
3013 is expanded only once, thus config.status (and configure) is smaller.
3015 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3016 the AC_LIST_FILES and cousins macros are no longer used.
3018 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3019 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3020 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3021 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3022 contain the initialization, nor the for loop, nor the associated
3023 commands; all these go to ...
3024 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3025 _AC_OUTPUT_CONFIG_STATUS.
3026 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3027 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3028 (_AC_OUTPUT_FILE): The creation of the sed script ...
3029 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3030 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3031 _AC_OUTPUT_MAIN_LOOP.
3032 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3033 _AC_CONFIG_COMMANDS): Use ...
3034 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3035 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3036 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3037 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3038 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3039 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3041 (_AC_CONFIG_UNIQUE): Update.
3042 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3043 Replaced by this ...
3044 (_AC_LIST_TAGS): ... new common macro.
3045 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3046 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3047 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3048 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3049 this didn't belong to the `config commands' section.
3050 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3051 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3052 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3053 to the `config commands' section either.
3054 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3055 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3057 ... and many changes to the comments nearby.
3059 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3060 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3061 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3062 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3063 (#define header templates): The comment at the top of the generated
3064 header now includes the name(s) of the source file(s).
3066 Several unrelated small changes:
3068 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3069 parameter to AC_DIAGNOSE.
3070 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3071 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3072 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3073 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3075 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3076 in AC_OUTPUT doesn't double-quote it either.
3077 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3080 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3082 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3083 versions of Portland Group compiler produce single- and double-quoted
3084 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3085 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3087 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3089 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3090 This is a corrected version of yesterday's patch.
3092 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3094 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3095 path, too; insert a "===" to emphasize the line.
3097 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3098 ac_cv_build_alias to ac_build_alias.
3099 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3101 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3102 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3103 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3104 (AC_ARG_VAR): ... here.
3105 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3108 Keep a list of all precious variables and process them with one simple
3109 for loop, instead of expanding all commands, or, OTOH, complicated
3110 processing of output of "set".
3111 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3112 variable names in new macro...
3113 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3114 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3115 a loop to assign all ac_env_* and ac_cv_env_* variables.
3116 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3118 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3119 its value to shell variable ac_precious_vars and call
3120 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3121 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3122 _AC_ARG_VAR_VALIDATE.
3124 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3125 and the AC_SUBSTs ...
3126 (AC_INIT): ... here.
3128 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3129 the ac_subst_files section in config.log.
3131 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
3133 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

3142 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3143 They are generated by the Tru64 v5.1B shell.
3145 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3147 Fix my changes from 2005-07-01; reported by Noah Misch.
3148 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
3149 description, the macro now accepts only a single tag.
3150 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
3152 Fix cases when the varsions of Autoconf and Autotest don't match.
3153 Reported by Noah Misch.
3154 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
3155 at_top_builddir, for compatibility with older autotest.
3156 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3157 is not set, use at_top_builddir, for compatibility with older
3158 versions of autoconf.
3160 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3162 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3163 Problem reported by Patrick Welche.
3165 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3167 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3168 sed substitution command, so that we allow | in program prefixes
3169 and program suffixes. (& is a problem anyway; we're not fixing
3171 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3172 configure_input, top_builddir, srcdir, etc.
3173 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3174 PATH_SEPARATOR in AUTOTEST_PATH.
3176 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
3178 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
3179 for loop over config.site files using `set', to allow
3180 directory names containing IFS characters.
3182 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
3184 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
3185 directories with weird names. Apparently some people like living
3186 on the edge. However, improve the test that "pwd" actually does
3187 report a name for the working directory.
3188 * NEWS: Remove the claim that we test for funny chars in dir names.
3190 2005-07-01 Stepan Kasal <kasal@ucw.cz>
3192 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

3203 (Generic Functions): Mention the Gnulib project.
3204 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
3206 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
3207 document to output the default config_* lists to config.status.
3208 Don't recognize option --file, if the functionality is not there.
3209 Likewise for --header; moreover, recognize --he and --h as shortcuts
3210 for --help in that case.
3212 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3213 matches the order of execution. No code changed.
3215 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3217 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

3225 2005-06-29 Stepan Kasal <kasal@ucw.cz>
3227 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
3228 descriptors to child processes; reported by Norman Gray.
3230 2005-06-29 Stepan Kasal <kasal@ucw.cz>
3232 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
3234 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
3235 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3236 (AC_SUBST): Call it.
3237 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3238 the directory specific variables; but don't call it for configure_input.
3240 2005-06-28 Derek Price <derek@ximbiot.com>
3242 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3245 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3247 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3248 directory have inherent problems with special characters like spaces,
3249 due to limitations in Make syntax. Problem reported by Alexandre
3251 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
3252 Also, fix Tru64 porting problem with shell patterns,
3253 reported by Ralf Wildenhues.
3255 2005-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3257 * doc/autoconf.texi (Subdirectories): Fix markup typos.
3259 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3261 * tests/local.at (AT_CHECK_ENV): Simplify regexp slightly.
3263 Fix some more shell quoting problems. Prompted by a bug report
3264 from Justace Clutter.
3265 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
3266 variable into diagnostic. Make the diagnostic an error, not a warning,
3267 because we really don't support spaces and suchlike in dir names.
3268 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3269 Don't worry about backslashes in srcdir; it can't happen now.
3270 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
3271 Simplify ac_optarg handling.
3272 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

3278 * tests/atlocal.in: Propagate $EGREP and $SED.
3279 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
3280 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3282 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3283 that '\|' is not allowed in BREs; recommend using newline separated
3284 list of patterns instead of multiple -e options.

3292 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
3294 2005-06-21 Stepan Kasal <kasal@ucw.cz>
3296 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3297 b, t, r, w commands require single space, while : cannot have any.
3298 (Special Shell Variables): Fix sed code this in the example.
3299 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3300 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3302 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

3306 2005-06-20 Derek Price <derek@ximbiot.com>
3308 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
3310 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
3312 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3313 * doc/autoconf.texi:
3314 Don't mention Solaris versions so much, if a
3315 problem is common to all extant versions of Solaris. Say "SunOS
3316 4" instead of "SunOS" for SunOS 4.
3317 (awk): Mention more of the limitations of traditional Awk.

3328 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3329 on Mac OS X 10.4 reported by Peter O'Gorman in:

3331 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
3332 Use shell builtins rather than 'expr', to work around expr bug.
3334 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3336 * doc/autoconf.texi: "filesystem" -> "file system".
3337 "behaviour" -> "behavior".
3338 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
3339 * lib/autoconf/general.m4: Omit blank after ":" sed command,
3341 * lib/m4sugar/m4sh.m4: Likewise.

3343 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
3345 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.

3360 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3361 -u, since it outputs chatter if the input files are the same.
3362 Problem reported by Ralf Menzel.
3364 2005-06-08 Derek Price <derek@ximbiot.com>
3366 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3367 renaming them since they are about to be redefined anyhow.
3369 2005-06-08 Derek Price <derek@ximbiot.com>
3371 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3372 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3373 Move m4_undefine to alphabetical order.
3375 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3377 * README: Recommend GNU M4 1.4.3 or later.
3378 * doc/autoconf.texi (Introduction): Likewise.
3379 Reword to avoid some formatting glitches.

3381 Clarify explanation of HP compiler bug.
3382 Redo example output tp match current CVS snapshot.
3383 Use @example.org in email addresses when the examples
3384 might get inadvertently cut-and-pasted into user code.
3385 Remove example of autom4te usage that doesn't seem to work now.
3386 Use modern AC_INIT (except when the example is meant to be
3387 shown with Autoconf 2.13).
3388 Update ksh info for Solaris 9 and later.
3390 Modernize description of Automake versions a bit.
3391 Don't claim a future version of Autoconf is near.
3392 * doc/install.texi: Reword to avoid some formatting glitches.
3394 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3397 follows its own advice about quoting better.
3398 Reword to avoid some formatting glitches.
3399 * doc/installt.exi: Reword to avoid some formatting glitches.
3401 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3402 Tru64 ksh pattern matching bug. Reported against Libtool by
3403 Albert Chin <libtool@mlists.thewrittenword.com> and
3404 Nicolas Joly <njoly@pasteur.fr>.
3406 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3408 m4_cdr of one-member list was [[]] (one-member list containing an
3409 empty string) instead of [] (an empty list. Callers were skewed to
3410 match this misbehaviour. As a consequence of this:
3411 - m4_foreach([x], [], [foo]) expanded to `foo', while
3412 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3413 This bug has been fixed:
3415 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3416 expand to an empty string; print error msg if called without
3418 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3419 misbehaviour; handle [] and [[]] correctly.
3421 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3423 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

3425 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
3427 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3429 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3430 swallow records with more than 99 fields.
3431 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3432 parse the long line.
3434 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3436 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3437 swallow literals longer than 399. Reported by Ralf Wildenhues.
3438 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
3439 to workaround this limitation.
3441 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3443 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3444 to gfortran, and make these the first two compiler names
3445 checked (following the general autoconf preference for gcc).
3447 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3449 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3450 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3451 (testsuite): Make sure autotest.m4f is up-to-date before using it.

3455 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3456 expression of unbounded size when processing the --list
3457 option. This runs afoul of a limit of 399 bytes per regular
3458 expression on AIX. Problem reported by Ralf Wildenhues.
3460 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

3463 * doc/autoconf.texi (Particular Headers): Reword example
3464 for multiline stdbool replacement.
3465 (Setting Output Variables): Reword text a bit. Don't
3466 give all the details about |#_!!_#|.
3467 Reword description of line replacement.
3469 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3471 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3472 now contain newlines, and substituted files must be referenced on
3473 a line alone; the sed scripts to substitute them are now very
3475 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3476 commands can be put in a sed script portably.
3477 * doc/autoconf.texi (Setting Output Variables): Document above
3478 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3479 use of multiline substitution.

3490 classes in shell scripts. The test was too brittle.
3492 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3494 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3495 * doc/autoconf.texi (Limitations of Builtins): Document this
3498 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3500 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3501 common code; used in many places in the tree.
3502 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
3503 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
3505 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
3507 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
3508 messages when ac_unique_file is not found.
3509 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3510 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3511 commands, for consistency with AC_MSG_ERROR and such.
3513 * bin/autoconf.as: Make more use of "shift 2" in option processing.

3526 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3527 (ac_top_builddir): ... this ...
3528 (ac_top_build_prefix): ... to this; the old name is also kept, for
3529 backward compatibility.
3530 (ac_top_builddir_sub): New variable, without the trailing slash,
3532 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

3546 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3547 argument to m4_foreach. I guess it was necessary in the past,
3548 but I think it's a no-op now.
3550 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3552 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3553 ``cat <<_ACEOF'' commands to one.

3686 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3687 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3688 comment and reduce m4_default([foo], []) to [foo].
3689 (m4_strip): Update the explanation.
3691 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3693 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3694 Remove core.conftest.* too; it's generated by Tru64 5.1.
3695 Problem reported by Jennis Pruett.
3696 * lib/autoconf/functions.m4
3697 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3698 Don't bother to remove core files; AC_RUN_IFELSE should do that

3703 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

3745 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3746 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3747 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3748 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3749 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

3754 a directory whose name contains a special character like space,

3769 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3770 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3771 ac_pwd, and quote srcdir.
3772 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3774 * doc/autoconf.texi: Fix some systematic formatting problems.
3775 ".)" needs a following @: if not at the end of a sentence, and
3776 similarly for "!)". "etc." should be preceded by a comma.
3777 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3779 2005-03-22 Bruno Haible <bruno@clisp.org>
3781 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's

3793 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3794 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3795 from a Common Lisp's `cl'.
3796 (AC_PROG_CXX): Behave according to the documentation: don't
3797 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3798 make the variable CCC precious; use `cl.exe', not `cl'.

3801 Alexandre Duret-Lutz <adl@gnu.org>
3803 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3804 /dev/null, as "configure" shouldn't read stdin, and this insulates
3805 us from problems (e.g., when testing for "cl"). Also, do this
3806 redirection before invoking "hostname" or "uname", and keep the
3807 original input stream available via...
3808 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3809 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

3821 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3822 newline if neither \c nor -n work, as that would output two
3823 newlines. Prefer -n to \c. Reported by Stepan Kasal.

3827 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.

3831 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3833 Undo previous change, except keep the change to
3834 lib/autoconf/programs.m4 that replaced grep with shell
3835 pattern-matching. This is because net-snmp configure reads stdin.

3840 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3841 from /dev/null, as "configure" shouldn't read stdin, and this
3842 insulates us from problems (e.g., when testing for "cl").
3843 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3844 before invoking "hostname" or "uname".
3845 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3846 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.

3850 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3851 Also, replace grep with shell pattern-matching, to save a process.

3855 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,

3956 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

4019 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4020 Update the long comment explaining it.
4022 m4_require no longer writes an ``is required by'' line to the
4023 execution stack. It contains only one bit of non-redundant
4024 information: that the macro was required, not called. And even
4025 this bit is useless in most situations: have you ever met a macro
4026 which both calls and requires the same macro?
4028 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4029 (_m4_defun_pro_outer): ... only via this macro, for the outermost

4034 execution stack; slightly improve the out-of-a-defun error message.
4035 (_m4_divert_grow): New macro, counter for the temporary diversions.
4036 (_m4_require_call): Use it.
4037 * tests/m4sugar.at (m4_require): Expect output without the
4038 ``is required by'' messages.

4076 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4077 Warn about newline stripping in `` and $(). Update Solaris
4079 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4080 X insulates us from future changes to Posix.
4081 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

4130 (_m4_divert_n_stack): New macro; the expansion is
4131 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4133 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4134 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4135 stored in _m4_divert_diversion or _m4_divert_dump.
4136 (m4_divert_pop): When the parameter is given, compare the symbolic
4137 name with the last diversion pushed on the stack. Previously, the
4138 current diversion was compared with the numeric value of the
4139 diversion given as the parameter.
4140 (m4_require): If the macro hasn't been expanded yet, call ...
4141 (_m4_require_call): this new macro.

4174 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
4175 signals that the package uses Automake; a `Makefile.am' is typical but

4653 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4655 * doc/autoconf.texi (Function Portability): Document isinf and
4656 and isnan. From a suggestion by Kevin Ryde.
4658 * lib/Autom4te/General.pm (END): Return correct exit status even
4659 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4661 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4663 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4664 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4665 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4667 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4669 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4670 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4671 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4672 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4673 * lib/autom4te.in (Automake-preselections): Preselect
4674 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4676 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4678 * lib/autom4te.in (Automake-preselections): Preselect
4679 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4682 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4684 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4686 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4687 Document problem with "`""`" in pdksh POSIX mode.
4689 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4691 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4692 with pdksh, too. Problem reported by Patrick Welche via
4694 * doc/autoconf.texi (Shellology): Note that set -o posix is
4695 useful for pkdsh, too.
4697 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4699 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4700 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4701 Don't fail if ENV or BASH_ENV is readonly.
4702 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4703 etc. are read only. Problem reported by Ludovic Courtes.
4705 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4707 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4708 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4711 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4713 * doc/autoconf.texi (File System Conventions): Warn about
4714 names like "aux". Problem reported by Eric Blake.
4716 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4717 by zero instead of array size, so that we can use any arithmetic
4718 constant expression (instead of requiring an integer constant
4719 expression). This allows us to test expressions like DBL_MAX <
4720 LDBL_MAX, which didn't conform to the C standard using the old
4722 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4723 now that we can do floating-point tests at compile time.
4725 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4727 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4728 and LDBL_EPSILON, as the resulting expression isn't an
4729 integer constant expression and violates the C standard.
4730 Problem reported by Nelson H. F. Beebe. Also, check
4731 for "L" suffix, and check that long double doesn't have
4732 worse range or precision than double, that mixed-mode
4733 arithmetic doesn't generate a diagnostic, that double
4734 constants fit in long double.
4736 2004-06-03 Kevin Ryde <user42@zip.com.au>
4738 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4739 malloc(0) and realloc(NULL,size).
4741 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4744 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4746 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4747 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4750 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4752 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4753 can be rewritten using if-then-else. Suggested by Bruno Haible.
4755 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4757 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4758 Problem reported by Stepan Kasal.
4760 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4762 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4763 change). Patch reported by Ralf Wildenhues in
4764 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4766 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4767 function F exists if the compiler and linker let you compile an
4768 expression like (F != 0). Recent versions of GCC optimize away
4769 the reference to F in that case, since every function address must
4770 be nonzero, so the link succeeds even if F does not exist.
4771 Problem reported by Manu in
4772 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4774 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4775 "Unix". Many uses changed.
4776 (Limitations of Builtins): Explain better why the ! command isn't
4779 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4781 * lib/autom4te.in (Automake-preselections): Preselect
4782 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4784 2004-05-19 Kevin Ryde <user42@zip.com.au>
4786 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4787 referencing AC_FUNC_STRERROR_R.
4789 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4790 note pessimistic assumption when cross compiling.
4792 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4794 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4795 (until 2004) invoked subcommands with sh -e, contra POSIX.
4796 Reported by Kevin Ryde.
4798 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4800 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4801 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4802 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4803 `test -f " /usr/bin/grep"', which _always_ failed.
4804 (AC_PROG_SED): Ditto bogus PATH fix.
4805 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4806 requires that grep correctly supports _multiple_ `-e' options, rather
4807 than stating only that grep should accept `-e'.
4809 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4811 Port to C99, which requires that 'exit' be declared.
4813 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4814 to ensure that stdlib.h is included.
4815 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4816 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4817 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4818 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4819 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4820 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4821 when using 'exit' in a test; C99 requires that 'exit' be declared.
4823 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4825 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4826 now prefers 'grep' implementations that accept -e.
4827 (Limitations of Usual Tools): Describe problems of traditional
4828 egrep and fgrep with long input lines, and of traditional grep
4830 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4831 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4832 All callers changed. Append /usr/xpg4/bin to the PATH, for
4834 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4835 the user with complaints about multiple -e options.
4836 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4837 Define it with AC_PROG_GREP.
4838 * configure.ac (AC_PROG_GREP): Add.
4839 * lib/freeze.mk (GREP): New macro.
4841 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4843 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4844 a possible candidate only after all others fail, rather than
4845 consulting it first. This improves backward compatibility by
4846 better reflecting the way shell selection occurred in previous
4847 versions of Autoconf, and should help to avoid triggering latent
4848 problems in other packages, such as the one in Automake where zsh
4849 is not handled robustly:
4850 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4851 Although it is not Autoconf's responsibility to work around
4852 problems in Automake, it nevertheless makes sense to avoid
4853 introducing unnecessary incompatibilites.
4855 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4856 Gary V. Vaughan <gary@gnu.org>
4858 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4859 how deeply nested we are when a suitable tool is found, set the
4860 ac_path_TOOL_found flag.
4861 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4862 nested we are in this macro. Break out of all 3 nested loops if
4863 ac_path_TOOL_found is set.
4865 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4867 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4868 of the _AS_PATH_WALK loop too if GNU flavor is found.
4870 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4872 * doc/autoconf.texi (Limitations of Make): Update documentation
4873 for `$<'. New entry `Long lines', based on a report from Simon
4874 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4875 paragraph about DJGPP, based on a mail from Richard Dawe.
4877 2004-04-20 Paul Eggert <eggert@twinsun.com>
4879 * tests/c.at (C keywords): Don't assume that GCC supports
4880 "restrict" and "inline", as sufficiently-old GCC versions do not
4881 (also, GCC configured to be in pedantic C89 mode does not).
4882 Problem reported by Sumit Pandya in:
4883 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4885 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4886 consider -g to work if it generates warnings when plain compiles
4887 don't. Problem reported by Braden McDaniel in:
4888 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4890 * doc/autoconf.texi (Slashes): New section, to document a problem
4891 reported by Jim Meyering in:
4892 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4894 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4895 linker output files before linking, to work around IRIX 6 linker bug.
4896 Problem reported by Rainer Orth in:
4897 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4899 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4901 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4902 best tool so far counter rely on the tool path variable name to
4903 avoid checks for one tool being affected by the results of running
4904 the length check on a previous tool.
4906 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4907 match expression argument, as different greps have different
4908 regular expression flavours.
4909 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4911 (AC_PROG_EGREP): Pass 'EGREP$'.
4912 (AC_PROG_GREP): Pass 'GREP$'.
4914 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4916 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4917 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4919 2004-03-29 Paul Eggert <eggert@twinsun.com>
4921 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4922 Types, Specific Compiler Characteristics, System Services,
4923 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4924 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4925 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4926 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4928 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

4930 AC_TYPE_OFF_T): Likewise.
4931 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4934 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to

4937 2004-03-28 Paul Eggert <eggert@twinsun.com>
4939 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4940 now defines HAVE_DECL_TZNAME if it is declared, when
4941 HAVE_STRUCT_TM_TM_ZONE is not defined.
4942 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4943 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

4950 thanks to Paul Eggert.
4952 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4954 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4955 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4956 H. F. Beebe for the bug report.
4958 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4960 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4961 quoted -cmdline argument in Portland Group compiler (bug
4962 reported by Jeffrey J. Barteet).
4964 2004-03-25 Kevin Ryde <user42@zip.com.au>
4966 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4967 (Run Time): ... here, where it's now mentioned.

5006 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5007 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5010 2004-03-03 Paul Eggert <eggert@twinsun.com>
5012 * bin/Makefile.am (edit): Don't use $< in a context where
5013 POSIX doesn't require support for it. Use $@.in instead.
5014 Problem reported by Anthony N. Frasso in
5015 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5016 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

5026 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
5027 is not always thread-safe. Report from Nathanael Nerode.
5029 2004-02-18 Paul Eggert <eggert@twinsun.com>
5031 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5032 problem on QNX reported by Stephen Rasku in

5044 AC_SUBST provides no portable way to escape literal newlines.
5046 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5047 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5048 Darwin uses -lcrt2.o and there's little point to cataloging all
5049 the system variants. Partial fix reported by Andreas Waechter in:

5066 the behavior of the third argument.
5067 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5068 correctly the behavior of the third argument. Document
5069 what the three macros that AU_DEFUN defines do. Fix
5070 warning message when the third argument includes $0
5071 (reported by Alexandre Duret-Lutz).

5074 Eric Sunshine <sunshine@sunshineco.com>

5088 (_AS_RUN): Move it here, support testing with eval.
5089 (AS_REQUIRE_SHELL_FN): Require shell functions when
5091 (_AS_LINENO_WORKS): Put around braces, we do not
5092 trigger the bash bug anymore.
5093 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5094 use AS_INIT_WITH_SHELL_FN.
5095 * bin/autoconf.in, tests/wrapper.in: Regenerated.

5139 egrep and fgrep respectively if $GREP -E/-F don't work.
5140 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5141 _AC_PROG_GREP, and AC_PROG_SED.

5174 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5175 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5176 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5177 not <inttypes.h>. Problem reported by Tim Mooney in
5178 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5179 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5182 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5183 otherwise "make check" fails because it forbids cmp (I guess
5184 because cmp treats files as binary on DOS-like systems).

5199 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5200 -std1 disables some useful extensions on Tru64. Problem reported

5204 2004-01-14 Paul Eggert <eggert@twinsun.com>
5206 * doc/autoconf.texi (Programming in M4sh): Document that
5207 AS_MKDIR_P succeeds if the destination is a symbolic link
5208 to an existing directory.
5209 (Limitations of Usual Tools): Note that mkdir -p might not
5210 succeed on symlinks to directories.
5212 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5214 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

5228 2004-01-09 Paul Eggert <eggert@twinsun.com>
5230 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5231 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5232 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5233 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5234 AC_COMPILE_IFELSE, since we now assume our caller invokes
5235 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5236 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5237 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5238 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5240 2004-01-07 Paul Eggert <eggert@twinsun.com>
5242 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5243 `"'...'"`, as it's confusing (and I suspect it may not work on
5244 some platforms). The code was incorrect anyway, as it assumed
5245 that \$ evaluated to itself in that context. Reported by
5246 Alexandre Duret-Lutz.
5248 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
5250 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

5283 * Makefile.am (autom4te-update):
5284 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

5300 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5301 -c -o might not work. From a suggestion by Kevin Ryde.
5302 (C Compiler, Generating Sources, Limitations
5303 of Usual Tools, Limitations of Make, Making testsuite Scripts):

5314 Fix typo: mkdir without umask arg.
5316 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
5318 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
5319 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

5321 explanation clearer.

5332 * tests/atlocal.in: Store the result here.

5590 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
5592 2003-10-10 Andreas Schwab <schwab@suse.de>
5594 * bin/autoheader.in: Avoid empty first line in --version and
5596 * bin/ifnames.in: Likewise.
5598 2003-10-09 Paul Eggert <eggert@twinsun.com>
5600 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
5601 Issue a more-informative diagnostic.
5602 Problems reported by Eric Sunshine.
5604 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5606 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5607 -mGLOB_options_string stuff for Intel ifc, which can cause
5608 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
5609 pattern-matching instead of grep.
5611 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5613 * doc/autoconf.texi: Document new FC Fortran macros.
5615 2003-10-08 Gary V. Vaughan <gary@gnu.org>
5617 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
5618 that future autopoint/aclocal/automake/autoreconf will be able
5619 to trace to find where to install local m4 macros.
5620 * doc/autoconf.texi (Input): Document it.
5623 2003-10-06 Gary V. Vaughan <gary@gnu.org>
5625 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
5626 -lcrtbegin.o to list of ignored flags and fix underquoting of
5629 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
5631 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5632 cache variable instead of $G77 to decide whether to include -O2,
5633 since $G77 is specific to Fortran 77.
5635 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5637 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
5638 free" flag. Re-order flags tested into rough order of popularity.
5640 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5642 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5643 arguments so that it can be used with syntax identical to
5644 AC_PROG_F77, and so that we can more easily decide to
5645 remove/deprecate the DIALECT optional argument in the future if it
5647 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5648 non-freeform-supporting compilers. Document freeform flags.
5650 2003-10-03 Akim Demaille <akim@epita.fr>
5652 * configure.ac: Look for emacs, not macs.
5653 Reported by Eric Sunshine.
5655 2003-10-03 Akim Demaille <akim@epita.fr>
5657 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5658 * bin/autoreconf.in (autoreconf_current_directory): Create the
5659 AUX_DIR if needed, for sake of automake --add-missing etc.
5660 Suggested by Alexandre Duret-Lutz.
5662 2003-10-03 Akim Demaille <akim@epita.fr>
5664 * configure.ac: Quotation and formatting changes.
5665 (EMACS): Don't set it if it is not recent enough to support
5669 2003-10-02 Akim Demaille <akim@epita.fr>
5671 * bin/ifnames.in (&scan_file): Skip C++ comments.
5674 2003-10-01 Pavel Roskin <proski@gnu.org>

5683 2003-09-30 Paul Eggert <eggert@twinsun.com>
5685 * lib/Autom4te/XFile.pm: Use Errno.
5686 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
5687 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

5693 (&news_file): Rename as...
5696 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
5698 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
5699 have been created when invoking the compiler.
5700 * tests/fortran.at (GNU Fortran 77): Quote $G77.
5702 2003-09-29 Akim Demaille <akim@epita.fr>
5706 * config/mkinstalldirs: Upgrade.
5708 2003-09-28 Paul Eggert <eggert@twinsun.com>
5710 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
5711 Problem reported by Lars J. Aas in
5712 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
5713 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5714 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5715 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5717 2003-09-26 Akim Demaille <akim@epita.fr>
5719 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5720 directory for AC_CONFIG_COMMANDS' first argument exists.
5721 This makes valid the invocation of _AC_SRCPATH that follows.
5722 Reported by Eric Sunshine.
5723 * doc/autoconf.texi (Configuration Commands): Adjust.
5725 2003-09-26 Akim Demaille <akim@epita.fr>
5727 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5728 Reported by Ralf Corsepius.
5730 2003-09-26 Akim Demaille <akim@epita.fr>
5732 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5734 Actually, use AU_ALIAS.
5737 2003-09-26 Paul Eggert <eggert@twinsun.com>
5739 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
5740 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
5741 Problem reported by Eric Sunshine in:

5744 2003-09-26 Akim Demaille <akim@epita.fr>
5746 The test suite are sometimes assigning timings incorrectly.
5747 Reported by Henk Krus.
5748 Diagnosed by Nicolas Joly.
5750 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5752 Instead of making AT_help a sequence of assignments to grow
5753 $at_help_all, just make AT_help_all be the growing contents of
5754 $at_help_all, and make a single assignment in...
5756 (at_times_skip): Flip the meaning and rename as...
5758 (AT_INIT): When summarizing the test that ran, remove
5759 $at_times_file after use, and check it is present before trying to
5762 2003-09-25 Akim Demaille <akim@epita.fr>
5766 * bin/Makefile.am (edit): Handle '@configure_input@'.
5767 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5768 (ifnames): chmod -w.
5769 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5770 executables, not bin/ executables! Otherwise all the magic needed
5771 to find non installed files is turned off. This caused a failure
5772 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5773 as found in its environment (sent by tests/autoreconf): pointing
5774 to bin/autom4te that could not find its files.
5775 * tests/mktests.sh: Force the replacement of generated files, for
5776 the sake of "mv" program that are interactive when overwriting a
5778 * config/install-sh: Upgrade from CVS Automake.
5780 2003-09-23 Paul Eggert <eggert@twinsun.com>
5782 * doc/autoconf.texi (Limitations of Builtins): Document test -h
5783 versus test -L issues.
5785 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
5786 Paul Eggert <eggert@twinsun.com>
5788 Trivial change to support GCC's configuration procedure.
5789 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5790 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5791 about inconsistency if the preprocessor is set to give errors for

5795 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
5797 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
5798 and XFile.pm from Automake.

5819 From Peter Hendrickson.
5821 2003-09-10 Akim Demaille <akim@epita.fr>
5823 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5824 willing to edit the output files.
5826 2003-09-10 Akim Demaille <akim@epita.fr>
5828 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5830 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5831 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

5851 2003-09-05 Paul Eggert <eggert@twinsun.com>
5853 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5854 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5856 2003-09-04 Akim Demaille <akim@epita.fr>

5867 2003-09-04 Akim Demaille <akim@epita.fr>
5869 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5871 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5873 Add support for newer Fortran dialects. The F77 interface is
5874 unchanged, and continues to support Fortran 77. New FC macros
5875 correspond to all the old F77 macros, with output variables FC,
5876 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5877 available dialect, but older dialects can be specified. There are
5878 new macros AC_FC_SRCEXT to set the source extension, and
5879 AC_FC_FREEFORM to accept free-form source files.
5881 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

5909 Document problems with timestamp resolution that 'make', 'cp -p', and
5912 2003-08-27 Akim Demaille <akim@epita.fr>
5914 * tests/m4sugar.at (cross_warning): Make sure to enable the
5915 output, so that we can track spurious m4sugar output.
5916 * tests/local.at: Require 2.57.
5917 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5918 are defaulted by AT_CHECK anyway.
5919 Use AT_CHECK_AUTOM4TE.
5920 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5923 2003-08-27 Akim Demaille <akim@epita.fr>

5977 Replace the former...
5978 (m4_warn): Pass the call stack to _m4_warn.
5979 * bin/autom4te.in: Adjust to output the call stack.
5980 * tests/m4sugar.at (m4@&t@_warn): Adjust.
5982 2003-08-22 Akim Demaille <akim@epita.fr>
5984 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.

5995 Use &verb, not &verbose.
5997 2003-08-21 Akim Demaille <akim@epita.fr>
5999 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6001 ($help): Use Autom4te::ChannelDefs::usage.
6002 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6003 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6005 2003-08-21 Akim Demaille <akim@epita.fr>
6007 First stab at preserving warnings between calls to autom4te,
6008 including when the cache is used.
6010 There are still several issues: (i) there are too many runs of m4
6011 (one for include, one for warnings, and some more), (ii) warnings
6012 spreading on several lines are not handled gracefully, (iii) the
6013 code meant to have the call stack display for errors does not work
6014 (its handling should move from m4 to autom4te).
6016 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6018 (@preselect): Add m4_warn.
6019 ($exit_status): Remove, use $exit_code.
6020 ($help): Use Autom4te::ChannelDefs::usage.
6021 (&handle_m4): No longer define the m4_warnings.
6022 At each run, extract and report the warnings.
6023 Always cache the result, including if the exit status is on
6024 failure, since if nothing changes, we should result in the same
6025 failure, hence we can use the cache.
6026 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6027 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6029 (m4_warn): Redefine as a do-nothing: it is its invocation that
6030 matters, as warnings are now reported via traces.
6031 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6032 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6033 the latter reveals calls to the former.
6037 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6039 2003-08-21 Akim Demaille <akim@epita.fr>
6041 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6044 2003-08-21 Akim Demaille <akim@epita.fr>
6046 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6048 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6049 (&parse_warnings): Accept a list of warning requests.
6050 (&usage): Return a string, not a side effect.
6051 (cross): New warning category.

6061 * bin/autoscan.in: Adjust.
6063 2003-08-20 Akim Demaille <akim@epita.fr>
6065 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6066 Reported by Alexandre Duret-Lutz.
6068 2003-08-20 Akim Demaille <akim@epita.fr>
6070 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6071 * bin/autom4te: Adjust.
6072 In particular, be Autoconf tools are really silent when properly
6073 working, bind the verbosity of the 'note' channel to $verbose.
6074 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6075 (&xsystem, &contents): Remove, since they are exported by...
6076 * lib/Autom4te/FileUtils.pm: this.

6136 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
6137 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6138 shorter column three. Add DESCRIPTION to log file content.
6140 2003-08-13 Derek Price <derek@ximbiot.com>
6142 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6145 2003-08-12 Derek Price <derek@ximbiot.com>
6147 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
6148 (AT_CHECK_NOESCAPE): Move core functionality to...

6158 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
6159 in Bash 2.01. Problem reported by Brian Gough in
6160 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
6162 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
6164 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
6165 -lcrt1.o, for OS X. (trivial change)
6167 2003-07-07 Paul Eggert <eggert@twinsun.com>
6169 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
6170 inside '#ifndef __cplusplus'. Problem reported by
6173 2003-07-06 Bill Clarke <llib@computer.org>
6175 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
6176 'long', not 'int', for benefit of Sun's recent C++ compilers
6177 (trivial change). See:
6178 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

6184 * lib/Makefile.am (autom4te.cfg): Make it read only.
6185 Depend on Makefile since it contains substitutions.

6188 This change was made on autom4te.cfg which is generated.
6189 Reported by Raja R. Harinath.
6191 2003-06-25 Akim Demaille <akim@epita.fr>
6193 * doc/autoconf.texi (Header Portability): sys/mount.h.
6194 From Gareth McCaughan.
6196 2003-06-23 Akim Demaille <akim@epita.fr>
6198 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6199 not all of them. This fixes 1. the fact that when testing
6200 Autoconf there are many many config.log, 2. the incorrect use of
6201 top_srcdir to find config.log.
6202 Don't mix the detailed output of failed test with the summary of
6203 failures. Rather, append detailed log afterwards.
6205 2003-06-23 Akim Demaille <akim@epita.fr>
6207 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
6208 always run: output config.log on $at_group_log.
6210 2003-06-23 Akim Demaille <akim@epita.fr>
6212 * tests/torture.at (#define header templates): Don't use quotes in
6213 C++ comments as it puzzles Emacs' sh font-lock-mode.

6217 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
6218 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
6219 * tests/atspecific.m4: Rename as...

6226 2003-06-21 Kevin Ryde <user42@zip.com.au>
6228 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
6229 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
6230 ensuring we add -std1 for full-ANSI.

6233 Add index entries for portability of various standard header files.
6235 2003-06-20 Akim Demaille <akim@epita.fr>
6237 * configure.ac: Bump to 2.57b.

6257 Update from masters.
6259 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6261 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6262 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6263 (TEST_SCRIPT): New diversion.
6264 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6265 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6266 (AT_INIT): Support for expected failures.
6268 2003-06-02 Akim Demaille <akim@epita.fr>

6272 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6273 Autoconf nor Automake.
6274 (&contents): New, from Automake.
6277 2003-05-28 Paul Eggert <eggert@twinsun.com>
6279 * NEWS, doc/autoconf.texi (Particular Functions),
6280 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6281 is the inverse of localtime.
6283 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6285 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6286 (handle_exec_errors): New function. Work around $! being
6287 altered by WEXITSTATUS.
6288 (xqx, xsystem): Use handle_exec_errors.
6290 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6292 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6293 Do not call `_exit()', simply modify `$?'.
6294 (xsystem): Reset $! before running system, and check it afterward.
6295 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6296 63 for version mismatches.
6298 2003-05-23 Akim Demaille <akim@epita.fr>
6300 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6301 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6302 the middle of a line).
6303 * lib/m4sugar/m4sugar.m4: Likewise.
6304 Remove useless spaces in comments.
6306 2003-05-23 Akim Demaille <akim@epita.fr>
6308 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6309 exit 63, so that we (or Automake's "missing") can tell the
6310 difference with a plain failure.
6311 * doc/autoconf.texi (Notices): Adjust.
6313 2003-05-23 Akim Demaille <akim@epita.fr>
6315 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6316 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6317 White spaces cleanup.
6319 2003-05-22 Jim Meyering <jim@meyering.net>
6320 Paul Eggert <eggert@twinsun.com>
6322 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6323 Remove `#include <stdlib.h>' from the list; we should never
6324 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6325 resulting namespace pollution would cause other tests to fail.
6326 Configure scripts run with some older versions of g++ and HP's
6327 aCC would fail due to such an #include. Problems reported by
6328 Matthew Mueller in <http://bugs.debian.org/120704> and by
6330 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6331 In the test, use the test declaration before including <stdlib.h>,
6332 as that's closer to how it'll be used.
6334 2003-05-23 Akim Demaille <akim@epita.fr>
6336 * doc/autoconf.texi (Header Portability): ucred.h.
6339 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6341 Overhaul Autotest's logging: generate separate log files
6342 in testsuite.dir/NNN/testsuite.log, and append them to
6343 testsuite.log instead of re-running the test verbosely.
6345 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6346 file descriptor, write 0 to at_status_file instead of setting
6347 at_status=0, initialize some new variables (at_status_file,
6348 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6349 to rerun the tests, instead append the at_group_log to the
6350 at_suite_log when a test fails.
6351 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6352 with the AS_MESSAGE_LOG_FD redirected to stdout.
6353 (AT_CLEANUP): save the output status in $at_status_file
6354 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6356 (AT_CHECK): since tests are run with a redirected stdout,
6357 and used to be re-run in verbose mode, turn some $at_verbose
6358 into echo, and don't redirect the output of testing stdout
6361 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6362 the name of the debugging directory and information about
6365 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

6399 2003-05-22 Akim Demaille <akim@epita.fr>

6477 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
6479 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
6482 2003-05-06 Akim Demaille <akim@epita.fr>
6484 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6485 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6486 by aclocal.m4 is changed it might require the importing of another
6487 m4 extension file, i.e., aclocal must be run.
6489 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6490 (&parse_args): Use --force with aclocal if required and supported.
6491 (&autoreconf_current_directory): Use &run_aclocal.

6498 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6499 argument instead of a file name, so that the request file remains
6500 open during the whole autom4te run.
6501 ($icache_file): New.
6502 (&freeze): Lock the $icache_file.
6504 2003-04-29 Derek Price <derek@ximbiot.com>
6506 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6507 seperator with m4_append_uniq(). It doesn't work.
6508 (AT_CLEANUP): Add `;' to end of at_help_all.
6509 (AT_INIT): Allow --keywords to be specified more than once. When
6510 grepping $at_help_all for keywords, use the field and keyword
6511 seperators to ensure a complete keyword match. Alter at_prev handling
6512 to support the new --keywords behavior.
6514 2003-04-27 Karl Berry <karl@freefriends.org>
6516 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6517 align better with others. I also made some of the individual
6518 entries on one line, for brevity and to make it easier for me to
6519 sort my dir-example file in the Texinfo distribution :).
6521 2003-04-12 Jim Meyering <jim@meyering.net>
6523 * NEWS: Mention the new macro.

6590 * tests/torture.at (Configuring subdirectories): Require aclocal
6591 1.4, otherwise the test fails, as it does support configure.ac.
6592 This fixes the "test 40 failed" bug reports.
6594 2003-03-28 Akim Demaille <akim@epita.fr>
6596 * doc/autoconf.texi (C Compiler): `#line' portability.

6670 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
6671 to a shell that can handle redirection or quoting correctly.
6672 Override SHELL with the shell detected by configure.
6673 Use of $^O suggested by Tim van Holder.
6674 * bin/autom4te.in (BEGIN): Likewise.

6706 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
6707 to fix a mismatch between example and discussion.

6722 compiler says yeah, but preproc says nope, compiler is right.
6723 Conversely, prompt the reader to send a bug report to the
6724 maintainers of the package, not of Autoconf.
6726 2003-02-20 Klee Dienes <kdienes@apple.com>
6728 * bin/autoreconf.in (autoreconf_current_directory): Properly

6737 2002-12-23 Paul Eggert <eggert@twinsun.com>
6739 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6740 innocuous variant befor including <limits.h> or <assert.h>. This
6741 works around a bug reported by Albert Chin: HP-UX 11i
6742 (and earlier versions) have a <limits.h> that declares
6743 gettimeofday and many other functions.
6745 2002-12-03 Paul Eggert <eggert@twinsun.com>
6749 * NEWS, configure.ac: Update version.
6751 * doc/fdl.texi: Upgrade to FDL version 1.2.
6753 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6754 nontrivially in main's body, so that f's external declaration is
6755 not optimized away in AIX. This should fix the bug reported by
6757 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6759 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6760 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6761 defined, to support freestanding compilers. This should fix the
6762 bug reported by Momchil Velkov in
6763 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6765 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

6777 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6778 \(.*\) match is too long and there is something more to be checked.

6797 Update from masters.
6799 2002-11-14 Akim Demaille <akim@epita.fr>
6801 * Makefile.maint: Sync with Bison, i.e.:
6802 (po-check): Scan .l and .y files instead of the
6803 .c and the .h files that they generate. This fixes the bug
6804 reported by Tim Van Holder in:
6805 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6806 Look for N_ as well as for _. Try to avoid matching #define for
6810 2002-11-14 Akim Demaille <akim@epita.fr>
6812 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6813 From Paul Eggert and Albert Chin-A-Young.
6815 2002-11-14 Akim Demaille <akim@epita.fr>
6817 * doc/autoconf.texi (C Compiler): Solitary backslashes.

6820 2002-11-14 Kevin Ryde <user42@zip.com.au>
6822 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6823 than assigning in main, to avoid HP cc +O3 optimizing it away.
6825 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6827 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6828 option. Process --recheck after parsing all options. Pass -q
6829 option to configure on --recheck.
6830 (AC_OUTPUT): Pass -q from configure to config.status.
6831 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6832 arguments to record.
6833 * doc/autoconf.texi (config.status Invocation): Document
6834 config.status -q option.

6861 Reported by Ezra Peisach.
6863 2002-11-05 Akim Demaille <akim@epita.fr>
6865 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6867 We _have_ to stop using the old compatibility scheme that tried to
6868 avoid useless backslashes because Libtool 1.4.3 contains a
6869 AC_DEFINE([error_t], [int],
6870 [Define to a type to use for \`error_t' if it is not
6871 otherwise available.])
6872 We _have_ to quote the single quote and backslashes with \. The
6873 old compatibility scheme saw that ` was backslashed, and therefore
6874 did not quote the single quote. Hence before this patch, Autoconf
6875 was not compatible with Libtool.
6877 2002-11-04 Paul Eggert <eggert@twinsun.com>
6879 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6920 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6921 Make variable, not a shell variable.
6922 Suggested by Bruno Haible.
6924 2002-10-31 Akim Demaille <akim@epita.fr>

6959 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
6961 sparc_address_test returns void.
6962 Use it with an argument, as prototyped.
6965 2002-10-29 Akim Demaille <akim@epita.fr>

7329 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7330 aclocal invocation, as Gettext macros might not be visible to
7332 Instead of blindly running autopoint, scan configure.ac (not the

7535 2002-09-13 Akim Demaille <akim@epita.fr>
7537 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals

7608 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7609 (ifnames, autoscan, autom4te): Since we don't only depend on
7610 configure.ac variables (such as VERSION etc.), but also on prefix
7611 and so forth, depend on Makefile, not configure.ac.
7612 Reported by Alexandre Duret-Lutz.

7615 2002-09-05 Kevin Ryde <user42@zip.com.au>

7651 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7652 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7653 Also, tweak grammar: s/make sure to/be sure to/.
7655 2002-09-02 Paul Eggert <eggert@twinsun.com>
7657 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7658 directory names are generally preferable to physical names.
7660 2002-09-02 Akim Demaille <akim@epita.fr>
7662 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7663 Reported by Raja R. Harinath.
7664 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7665 * bin/autoupdate.in: Use error instead of die.
7667 2002-09-01 Paul Eggert <eggert@twinsun.com>
7669 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7670 ordinary shell concatenation rather than echo+tr+sed command that
7671 runs afoul of a long-line-related sed bug in Solaris 8.
7673 * bin/autoheader.in (parse_args): --warning -> --warnings.
7675 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7676 stdout, as traditional "ls" does.
7677 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7678 _AC_COMPILER_EXEEXT_O): Likewise.
7679 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7681 * bin/autoconf.as: Add --prepend-include option. This patch was
7682 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7683 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7685 * bin/autoconf.in, configure: Regenerate.
7687 * doc/autoconf.texi (Special Shell Variables): Mention
7688 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7690 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7691 MAILPATH and set PS1, PS2, PS4 to default values, to work
7692 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7693 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7694 the Autoconf documentation specifies; fall back to "unset" only if
7695 this fails. Use a shell for-loop for this rather than an m4 loop,
7696 to shorten the output script.
7698 2002-08-30 Paul Eggert <eggert@twinsun.com>
7700 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7701 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7702 for the CDPATH problem. Document PWD.
7703 (Limitations of Builtins): Document the problem that "cd $foo" and
7704 "ls $foo" may refer to different directories in shells conforming
7705 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7706 example, since the old example is now out of date.
7708 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7709 FOO" and "ls FOO" talk about different directories; this catches
7710 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7713 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7714 of rolling our own unset.
7715 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7716 in practice we needn't worry about CDPATH if unset doesn't work.
7718 * Makefile.in, aclocal.m4, bin/Makefile.in,
7719 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7720 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7721 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7722 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7723 tests/Makefile.in: Regenerate with Automake 1.6.3.
7725 * config/config.guess, config/config.sub, config/mkinstalldirs:
7728 * configure: Regenerate with self.
7730 2002-08-30 Kevin Ryde <user42@zip.com.au>
7732 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7735 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7737 * bin/autom4te.in (Request::load): Correctly test for "do" read
7740 2002-08-29 Akim Demaille <akim@epita.fr>
7742 * lib/Autom4te/General.pm (&xqx): New.
7743 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7744 hand, which is not portable.
7746 * bin/autom4te.in: Use them.
7747 Use &error instead of die.
7748 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7751 2002-08-17 Paul Eggert <eggert@twinsun.com>
7753 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7754 default list of compilers to try, since it was long ago superseded
7755 by the ksh fc builtin. Suggested by Steven G. Johnson.
7757 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7759 * doc/autoconf.texi (Invoking autom4te): End the option table,
7760 fixing a bug introduced by the previous patch.
7761 (Limitations of Make): Add a 'target lookup' subentry in the
7762 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7764 2002-07-29 Mark D. Roth <roth@feep.net>
7766 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7767 options and use $AUTOM4TE_PATH.
7768 * doc/autoconf.texi: Remove documentation of autom4te
7769 --include-envvar and --site-macro-subdir options and document
7770 use of $AUTOM4TE_PATH.
7771 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7772 arguments from each language section.
7774 2002-07-29 Paul Eggert <eggert@twinsun.com>
7776 * doc/install.texi: Include copyright symbol in copyright notice.
7778 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7780 (AM_MAKEINFOFLAGS): New macro.
7781 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7782 * Makefile.am (INSTALL): Use the new macros.
7783 Use -o rather than --output, since "missing" does not grok --output.
7785 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7787 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7788 comments do not always work. Never trust the exit status of
7791 2002-07-24 Kevin Ryde <user42@zip.com.au>
7793 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7794 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7796 2002-07-23 Paul Eggert <eggert@twinsun.com>
7798 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7799 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7800 apparently treats PATH="nonexistent" as if it contained ".".
7801 Bug reported by Stefan `Sec' Zehl.
7803 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7805 * doc/autoconf.texi (Limitations of Make): Mention the special
7806 handling of the obj/ directory by BSD make.
7808 2002-07-20 Kevin Ryde <user42@zip.com.au>
7810 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

7832 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
7835 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
7836 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
7837 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
7839 2002-07-18 Akim Demaille <akim@epita.fr>,
7840 Alexandre Duret-Lutz <duret_g@epita.fr>
7842 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
7843 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
7845 2002-07-17 Russ Allbery <rra@stanford.edu>
7847 * doc/autoconf.texi (Initializing configure): Clarify the
7848 description of the tarname default.

7920 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
7922 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7923 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
7924 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
7925 so that Emacs setups GNU style for perl-mode and cperl-mode.
7927 2002-06-27 Paul Eggert <eggert@twinsun.com>
7929 * config/install-sh: Quote $src. Prefer || to test's -o option,
7930 as per "Limitations of Builtins".

7932 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7934 * tests/mktests.sh: Use grep instead of fgrep, as per
7935 "Limitations of Builtins".
7937 2002-06-15 Paul Eggert <eggert@twinsun.com>
7939 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7940 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7941 so that we consistently test the just-built programs.
7942 * tests/wrappl.as: Likewise.
7944 2002-06-12 Paul Eggert <eggert@twinsun.com>
7946 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
7947 name, so that symlinks to 'autoconf' work properly. Bug reported
7949 * bin/autoheader.in (AUTOM4TE): Likewise.
7950 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7951 * bin/autoscan.in (autom4te): Likewise.
7952 * bin/autoupdate.in (autom4te): Likewise.
7954 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7955 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7958 2002-06-11 Andreas Schwab <schwab@suse.de>
7960 * doc/autoconf.texi: Add more dir entries.
7962 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7964 * bin/autom4te.in ($cache): Don't define using `$me', the name
7965 of the cache should not depend on the name under which autom4te
7968 2002-06-07 Akim Demaille <akim@epita.fr>
7970 * tests/tools.at (autoconf: forbidden tokens, basic)
7971 (autoconf: forbidden tokens, exceptions): Adjust to the change of
7972 words in autom4te.in.
7974 2002-06-07 Peter Eisentraut <peter_e@gmx.net>

7983 (AC_REPLACE_FNMATCH): this.
7984 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
7985 AC_FUNC_FNMATCH_GNU.
7987 2002-06-07 Akim Demaille <akim@epita.fr>
7989 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7990 Rosetta Stone for Unix.
7992 2002-06-07 Akim Demaille <akim@epita.fr>
7994 * bin/autom4te.in (warn_forbidden): When rejecting a token,

8010 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
8011 * tests/mktests.sh (ac_exclude_list): Don't check

8014 2002-06-06 Paul Eggert <eggert@twinsun.com>
8016 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
8019 * doc/autoconf.texi (Configuration Links): Likewise.

8047 2002-05-27 Paul Eggert <eggert@twinsun.com>
8049 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
8050 * NEWS, doc/autoconf.texi (Particular Types): Document it.
8051 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
8052 instead of AC_MBSTATE_T, which never existed.
8054 2002-05-23 Akim Demaille <akim@epita.fr>
8056 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
8057 version of Autoconf that is discussed.
8059 2002-05-22 Paul Eggert <eggert@twinsun.com>
8061 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8062 from the default list of compilers to try. Suggested by
8064 * NEWS: Document the above.
8065 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8067 2002-05-17 Paul Eggert <eggert@twinsun.com>
8069 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8070 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8071 This improves on an earlier suggestion by H. Peter Anvin.
8073 2002-05-16 Paul Eggert <eggert@twinsun.com>
8075 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8076 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8077 Both macros now accept an optional source-dir arg.
8078 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8080 * NEWS: Document this.
8081 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8083 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8084 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8085 not for GNU extensions; this undoes part of the 2000-11-03 change,
8086 reverting to 2.13-compatible behavior.
8087 Add new optional argument DIR.
8088 (AC_FUNC_FNMATCH_GNU): New macro.
8090 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8092 2002-05-08 Paul Eggert <eggert@twinsun.com>
8094 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8095 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8096 and it causes a 'test' syntax error if it fails.
8097 Bug reported by Stephen Gildea.
8099 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8100 If prototypes are supported, use them to check this at compile-time,
8101 instead of trying to check it at run-time. If we must do a run-time
8102 check, assume that setvbuf is standard when cross-compiling, as
8103 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8104 Bug reported by Paul D. Smith.
8106 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8107 argument specifying location of getloadavg.c. This removes a
8108 FIXME. This idea was taken from Jim Meyering's implementation in
8110 * doc/autoconf.texi (Particular Functions): Document this.
8111 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8112 that's what the code does; this fixes a bug reported by
8115 2002-05-03 Akim Demaille <akim@epita.fr>
8117 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8118 autopoint instead of gettextize.
8119 ($uses_alocal): Rename as...
8120 ($uses_aclocal): this.
8121 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8122 Suggested by Bruno Haible.
8124 2002-05-03 Akim Demaille <akim@epita.fr>
8126 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8128 2002-04-29 Paul Eggert <eggert@twinsun.com>
8130 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8131 files to be 1 second older; just set them to be the same time.
8132 Also, sleep 1 second after the first aclocal, to work around
8133 problems with sub-second time stamps on the input files.
8135 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>

8144 From Christian Cornelssen.
8146 2002-04-29 Akim Demaille <akim@epita.fr>
8148 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8149 of lack of $LINENO support, then the test will compare the $LINENO
8150 in testsuite vs. the lineno in the test file. This is wrong, of
8152 Be sure to protect it.
8153 Reported by Patrick Welche.
8155 2002-04-25 Akim Demaille <akim@epita.fr>

8158 Reported by Vladimir Volovich.
8160 2002-04-25 Akim Demaille <akim@epita.fr>
8162 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8163 than some of the input files, hence, on the second run of aclocal,
8164 if some of its input are younger, make them older.
8165 Suggested by Paul Eggert.
8167 2002-04-25 Akim Demaille <akim@epita.fr>

8179 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8180 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8181 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8182 _AC_SUBST_FILES and _AC_SUBST_VARS.
8183 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8185 2002-04-24 Akim Demaille <akim@epita.fr>
8187 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8188 autoheader, so that automake does not complain about a missing
8189 config.h.in that was to be created.
8191 2002-04-23 Akim Demaille <akim@epita.fr>
8193 * bin/autoheader.in (parse_args): --warning takes an argument.

8243 Minor spelling and grammar fixes.
8245 * doc/autoconf.texi: Follow the outline suggested in the GNU
8246 Sample Texts sections of the Texinfo 4.2 manual. Most
8247 importantly, this makes sure that the copyright notices appear in
8248 all output formats. You probably need Texinfo 4.2 to generate

8275 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8277 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8278 from aclocal.m4 too.

8286 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8287 workaround for ${1+"$@"}.
8288 * doc/autoconf.texi (Shell Substitutions): Explain it.
8289 From Oliver Kiddle and Peter Stephenson.
8291 Have M4sh perform minimal shell sanitizing.
8293 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8295 (_AS_PREPARE): this new macro.
8297 (AS_INIT): Invoke AS_SHELL_SANITIZE.
8298 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8300 Adjust Autoconf and Autotest.
8302 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8303 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8304 * lib/autotest/general.m4 (AT_INIT): Likewise.
8305 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

8309 Use this M4sh to generate Autoconf's shell scripts.
8311 * tests/wrapsh.as: New, precursor of wrapsh.in.
8312 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8313 on Autotest and M4sh.
8314 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8315 (wrapsh.in): New target.
8316 * bin/autoconf.as: New, precursor of autoconf.in.

8337 directories when descending in a SUBDIRS.
8338 Reported by Ezra Peisach.
8340 2002-04-04 Andreas Schwab <schwab@suse.de>
8342 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8343 contains no literal separators.
8345 2002-04-03 Akim Demaille <akim@epita.fr>
8347 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8348 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8349 Use dnl, not the KILL diversion.
8351 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8352 (AC_CONFIG_LINKS): here.
8354 Don't use the KILL diversion, as it kills spurious output, which
8355 results in failures being hidden.
8356 Use m4_defn where appropriate.
8357 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8358 after the second argument.
8360 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8361 syntax, as it is provided by M4sugar.

8406 2002-03-27 Paul Eggert <eggert@twinsun.com>
8408 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8409 (AS_SHELL_SANITIZE): Invoke it.

8426 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

8432 2002-03-21 Paul Eggert <eggert@twinsun.com>
8434 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8435 problem with here-document buffer boundaries.
8437 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8438 when reinvoking the shell, to work around problems with installers
8439 who put strange things like "cd" commands in their environments.
8441 2002-03-19 Akim Demaille <akim@epita.fr>

8464 (Limitations of Usual Tools): Add mkdir section.
8466 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8467 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8468 back on AS_DIRNAME to compute prefixes otherwise; this is
8469 roughly what mkinstalldirs does. That way, we need not have
8470 our own filename disassembler. The old disassembler did not
8471 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8473 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8474 Create at_test_all by a series of assignments,
8475 not by a single assignment of a long string. The latter causes ksh
8476 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8477 presumably because of a buffer overrun.
8479 2002-03-14 Paul Eggert <eggert@twinsun.com>
8481 * lib/autotest/general.m4 (at_times_skip):
8482 Renamed from at_times. Now a boolean.
8483 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8484 says 'times: not found'.

8534 aliases the actual variables, and modifications of the former
8537 2002-03-08 Akim Demaille <akim@epita.fr>
8539 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8540 because of C-c: have m4 output in tmp files, then mv them.
8542 2002-03-08 Akim Demaille <akim@epita.fr>
8544 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

8572 2002-03-04 Akim Demaille <akim@epita.fr>
8574 * doc/autoconf.texi (Transforming Names): Equality between target
8575 and host is irrelevant.
8576 (Specifying Names, Canonicalizing): Remove all references to the
8577 backward compatibility hooks. Rather, collect them all into...
8578 (Hosts and Cross-Compilation): this new section.
8579 * doc/install.texi (System Type): Ditto.
8580 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8581 that `--host' implies cross-compilation.
8583 2002-03-04 Akim Demaille <akim@epita.fr>
8585 * doc/autoconf.texi (Evaluation Macros): New.
8586 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8588 (_m4_foreach): Define the variant with immediate evaluation so
8589 that it contains exactly the items, not an expression which
8590 evaluation is the current item.
8591 (m4_re_string, m4_re_word): Don't over quote them.
8593 2002-03-04 Akim Demaille <akim@epita.fr>
8595 Instead of having stacking `shift's evaluated at the end, let
8596 `foreach' loops immediately evaluate them.
8598 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8599 $*. This is the n-th time I change my mind, but hopefully this is
8602 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8604 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8605 it was only a hack for m4_text_wrap.
8606 (m4_car2): Remove, replaced by...
8608 (_m4_foreach): Adjust.
8609 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8610 m4_bpatsubst for clarification.

8676 case/esac, some shells don't support it.
8677 Reported by Zack Weinberg.
8678 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
8680 2002-02-06 Akim Demaille <akim@epita.fr>
8682 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8683 sure not to introduce newlines in at_groups.
8684 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8686 2002-02-06 Akim Demaille <akim@epita.fr>
8688 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8691 2002-02-05 Paul Eggert <eggert@twinsun.com>
8693 * doc/autoconf.texi (Specific Compiler Characteristics):
8694 Describe HP-UX cc bug workaround more accurately.
8695 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
8697 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8698 cross-compilers, too. This undoes some of the most recent change
8701 2002-02-05 Akim Demaille <akim@epita.fr>
8703 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8704 to make sure they are up to date when `check' is run.
8706 2002-02-05 Akim Demaille <akim@epita.fr>
8708 * doc/autoconf.texi (Making testsuite Scripts): Document
8711 2002-02-05 Akim Demaille <akim@epita.fr>
8713 * lib/freeze.mk: New.
8715 2002-02-05 Akim Demaille <akim@epita.fr>
8717 Implement `autom4te --freeze'.
8719 * bin/autom4te.in (&freeze): New.
8720 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8721 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8723 2002-02-05 Akim Demaille <akim@epita.fr>
8725 * bin/autom4te.in (&parse_args): Implement `frozen files are
8726 optional are the sum of the previous files on the command line'.
8727 Also, pass `--reload-state=' on them, so...
8729 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8730 (M4sh): Rely on M4sugar.
8731 (Autotest, M4sh, M4sugar): Use frozen files.
8733 2002-01-31 Akim Demaille <akim@epita.fr>
8735 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8736 * doc/autoconf.texi (Initializing configure): Adjust.
8738 2002-01-30 Akim Demaille <akim@epita.fr>
8740 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8741 alphanumeric to `-' instead of `_'.
8743 2002-01-30 Akim Demaille <akim@epita.fr>
8745 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8746 for plain code, the other for cross-compilation code. The latter
8747 is now run with GCC only.
8748 * doc/autoconf.texi (Compilers and Preprocessors): New.
8750 2002-01-30 Akim Demaille <akim@epita.fr>
8752 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined

8763 2002-01-28 Akim Demaille <akim@epita.fr>
8765 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8768 2002-01-28 Akim Demaille <akim@epita.fr>
8770 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8771 AUTOTEST_PATH *after* it was set.
8772 Don't put `.' in the PATH: the user should be precise and `./' if
8773 needed. In addition, given that the test suite does some `cd', if
8774 `.' is in the path, the `tested programs' sections will report
8775 programs found in the test suite's directory, while during the
8776 tests (performed in their own directory), these programs are no
8777 longer visible. In other words, the results is confusing and
8779 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

8793 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8794 Bourne. Use /bin/sh.
8795 From Andreas Buening.
8797 2002-01-24 Akim Demaille <akim@epita.fr>
8799 * config/config.guess, config/config.sub, config/texinfo.tex:

8813 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8814 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.

8817 2002-01-21 Akim Demaille <akim@epita.fr>
8819 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
8821 2002-01-21 Akim Demaille <akim@epita.fr>
8823 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8824 message on invalid options.
8825 * bin/autom4te.in (parse_args): Don't use
8826 Autoconf::General::getopt with non valid options.
8828 2002-01-17 Jim Meyering <meyering@lucent.com>
8830 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8831 $ac_cv_exeext so we don't use an old, invalid, cached value.
8833 2002-01-11 Akim Demaille <akim@epita.fr>
8835 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim

8842 2002-01-06 Akim Demaille <akim@epita.fr>
8844 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8845 package.m4, since is really depends upon configure.ac, not
8847 * doc/autoconf.texi (testsuite Scripts): Adjust.
8848 * tests/Makefile.am (package.m4): New.
8849 EXTRA_DIST it since its a source.
8851 2002-01-06 Akim Demaille <akim@epita.fr>
8853 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8854 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8855 and PACKAGE_BUGREPORT from here...
8856 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8858 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8859 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8860 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8861 * tests/tools.at (autoheader): Adjust.
8862 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8864 2002-01-06 Akim Demaille <akim@epita.fr>
8866 * bin/autoscan.in (scan_file): Use `&used'.
8868 2002-01-03 Akim Demaille <akim@epita.fr>
8870 * doc/autoconf.texi (Output): Improved wording regarding use of
8874 2001-12-18 Kevin Ryde <user42@zip.com.au>
8876 * doc/autoconf.texi (Function Portability): Add notes on sscanf
8877 sometimes needing writable input.

8883 2001-12-14 Akim Demaille <akim@epita.fr>
8885 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8886 trailing files, don't apply `-rf' to files which might not be
8887 created by configure (core, core.*, and *.core), but just `rm -f'.
8888 Suggested by Jonathan Kamens.
8890 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8892 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8894 2001-12-14 Akim Demaille <akim@epita.fr>
8896 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8898 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8900 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8901 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8902 abs_srcdir, top_srcpath to abs_top_srcdir.
8903 (_AC_OUTPUT_FILES): Adjust.
8904 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8905 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,

8910 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8911 C/Fortran linking on HP/UX, by extracting the Fortran library
8912 search path from the LPATH line in the $F77 -v output.
8914 2001-12-12 Kevin Ryde <user42@zip.com.au>

8926 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8927 Remove $filepath, useless.
8928 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8929 variables, they are really part of the tokens.
8930 Split the input line on spaces and then look for tokens.
8931 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8932 because of `lex$U.$(OBJEXT)'.
8933 (&scan_files): Use "@list" instead of join.
8934 * doc/Makefile.am (CLEANFILES): Add *.fns.
8936 2001-11-26 Akim Demaille <akim@epita.fr>
8938 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8939 Remove, replaced by...
8940 * tests/wrappl.in: Be common for all the Perl executables.
8941 In particular autoscan and autoheader want -I.
8942 * configure.ac: Adjust.
8943 * lib/autoscan/headers: errno.h is portable.
8945 2001-11-26 Akim Demaille <akim@epita.fr>
8947 * bin/autoscan.in (used): New.
8950 2001-11-26 Akim Demaille <akim@epita.fr>
8952 * bin/autoscan.in (&scan_c_file): Better parsing of CPP

8958 2001-11-26 Akim Demaille <akim@epita.fr>
8960 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8961 Before, having a line containing the opening of a multi line
8962 comment made the whole line be ignored.
8964 2001-11-26 Akim Demaille <akim@epita.fr>
8966 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8967 (testsuite Scripts): Be one of its subsection.
8968 (Autotest Logs): New.
8970 2001-11-26 Akim Demaille <akim@epita.fr>
8972 Test groups are now run two directories deeper.
8974 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8975 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8977 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8978 top_srcdir, builddir and top_builddir.
8979 Use `at_*dir' relatively to the directory containing the
8980 suite, use `*dir' when relatively to the current group dir.
8982 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>

8989 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8991 * doc/autoconf.texi (Using System Type): Add an example of `case
8992 $host' usage so people quit using `case $target' everywhere.
8994 2001-11-22 Akim Demaille <akim@epita.fr>
8996 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8997 spotted by Jim Meyering.
8999 2001-11-16 Paul Eggert <eggert@twinsun.com>
9001 This patch implements a `long double' suggestion by Oliver Kiddle.
9003 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9004 static, to catch errors if the value isn't known at compile-time
9005 and the compiler supports dynamic arrays. Change its name from
9006 `_array_' to `test_array' to avoid potential name clashes.
9007 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9008 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9009 better than double. Catch a bug in GCC 2.95.2 x86.
9010 * doc/autoconf.texi (C Compiler): Document the above.
9013 2001-11-13 Akim Demaille <akim@epita.fr>
9015 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9017 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9019 2001-11-13 Akim Demaille <akim@epita.fr>
9021 * lib/autotest/general.m4 (AT_INIT): After having run the test
9022 group, go back to the initial directory, not to at_suite_dir.
9024 2001-11-13 Akim Demaille <akim@epita.fr>
9026 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9027 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9028 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9030 (AT_CHECK_CONFIGURE): Use absolute paths.
9031 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9032 The problem is still the old one: there is no means in M4 (that I
9033 know about) to create a defining macro, because there is no means
9034 to create `$1' etc., therefore, the defining macro ``swallows''
9035 all the arguments meant to the defined macro.
9037 2001-11-13 Akim Demaille <akim@epita.fr>
9039 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9040 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9042 * tests/aclocal.m4: Remove, as it is no longer used.
9044 2001-11-13 Akim Demaille <akim@epita.fr>
9046 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9047 variable names when referring to a single test group, or to
9048 `suite' when referring to the whole test suite.
9049 `at_last_test' is removed: m4 compute at_format itself.
9050 (at_stdout, at_stder1, at_stderr): New variables.
9051 (AT_CHECK): Use them.
9053 2001-11-13 Akim Demaille <akim@epita.fr>
9055 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9057 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9058 Do it as soon as a test fails, don't wait till the end of the test
9060 Don't remove $as_me.[0-9]*, since these files no longer exist.
9062 2001-11-13 Akim Demaille <akim@epita.fr>
9064 * tests/tools.at: Use absolute paths, since we are no longer run
9067 2001-11-13 Akim Demaille <akim@epita.fr>
9069 Now that tests are running in their own private dir, there is no
9070 need to list the files to remove at the end of tests groups.
9072 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9073 (AT_data_files, at_data_files): Remove.
9074 (AT_CLEANUP, AT_DATA): Simplify.
9076 Remove the group dir if !debug && !failed.
9077 * tests/atspecific.m4: Adjust.
9079 2001-11-13 Akim Demaille <akim@epita.fr>
9081 Start a new layout for Autotest: `testsuite' creates
9082 `testsuite.dir' in which the at-check-line etc. files are to be
9083 found, and `testsuite.dir/003' where the test group 3 is run.
9085 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9086 at_check_line_file, at_format, at_test_normalized, at_group_dir
9088 Create the directories.
9089 Use absolute paths for at- files.
9092 2001-11-11 Michael Matz <matz@kde.org>
9094 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9096 (m4_car): Properly quote arguments.
9098 2001-11-13 Akim Demaille <akim@epita.fr>
9100 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9101 with stricter rules on LIBOBJS.
9103 2001-11-12 Paul Eggert <eggert@twinsun.com>
9105 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9106 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9109 2001-11-12 Akim Demaille <akim@epita.fr>
9111 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9113 2001-11-12 Akim Demaille <akim@epita.fr>
9115 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9116 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9117 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9118 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9119 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9120 specify to what the macro should be defined (typically to 1).
9122 2001-11-12 Akim Demaille <akim@epita.fr>
9124 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9127 2001-11-12 Akim Demaille <akim@epita.fr>
9129 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9130 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9131 definition used by Automake where LEX is +/- "${missing} lex" and
9132 `missing' itself contains variables.
9134 2001-11-12 Akim Demaille <akim@epita.fr>
9136 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9137 Now that M4sh pushes BODY, the comments were output at the end of
9140 2001-11-08 Akim Demaille <akim@epita.fr>
9142 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9143 that we can trace macros from aclocal.m4.
9144 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9145 obsoleted, and redirect to the former anyway.
9146 Reported by Ralf Corsepius.
9148 2001-11-08 Akim Demaille <akim@epita.fr>
9150 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9151 processed only if present.
9152 * tests/torture.at (Configuring subdirectories): Use autoreconf
9153 instead of successive calls to autoconf.
9154 Add a nonexistent subdirectory to exercise the patch above.
9155 Reported by Ralf Corsepius.
9157 2001-11-08 Kevin Ryde <user42@zip.com.au>
9159 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9160 doesn't accept .S files.
9162 2001-11-07 Akim Demaille <akim@epita.fr>
9164 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9165 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9166 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.

9168 (handle_output): Use it.
9169 Read m4_pattern_forbid with messages.
9171 2001-11-05 Akim Demaille <akim@epita.fr>
9173 * bin/autom4te.in (--normalize): Remove.
9174 * lib/autom4te.in: Adjust.
9176 2001-11-05 Akim Demaille <akim@epita.fr>
9178 * tests/Makefile.am (testsuite): Rename this target as...
9179 ($(TESTSUITE)): this.
9182 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9184 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9185 the --prefix option, also remove it's argument.

9210 2001-11-03 Akim Demaille <akim@epita.fr>
9212 * lib/Autom4te/General.pm (@export_vars, @export_subs)

9214 Add basename, dirname, and fileparse.
9216 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9217 Don't look for aclocal flags if we already know aclocal is not
9219 Move aclocal.m4t only if it exists.
9220 Reported by Ezra Peisach.
9222 2001-11-03 Akim Demaille <akim@epita.fr>
9224 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9225 passed on command line, defaulting to ./configure.ac if present.
9226 (&maybe_autoreconf, File::Find): Remove, unused.
9227 (&autoreconf): If autoconf is not used, don't try to trace.
9229 2001-11-02 Akim Demaille <akim@epita.fr>
9231 * configure.ac: Bump to 2.52g.
9233 2001-11-02 Akim Demaille <akim@epita.fr>
9237 2001-11-02 Akim Demaille <akim@epita.fr>
9239 * config/config.guess, config/config.sub, doc/standards.texi:

9246 Don't run aclocal when aclocal.m4 is not from aclocal.
9248 Don't run libtoolize and gettextize if --install is not given.
9250 2001-11-01 Paul Eggert <eggert@twinsun.com>
9252 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9253 be invoked before _AS_LINENO_PREPARE.
9254 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9255 than character ranges.
9257 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9258 invoking AS_BASENAME. Set the locale variables to 'C' if
9259 possible, as POSIX requires this to get the traditional
9261 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9263 2001-10-31 Paul Eggert <eggert@twinsun.com>
9265 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9266 with {}, as that triggers a bug in Bash 2.05.
9268 (_AS_LINENO_PREPARE): Use Sed rather than
9269 Awk. Fix the sed prepass to work even if there are multiple
9270 instances of $LINENO on the same line. Do not substitute for
9271 other variables like $LINENOT. Do not check file dates; such a
9272 check is unreliable on sufficiently fast machines, and removing
9273 the check makes the code simpler and more reliable. Check for
9274 output and chmod failures.
9276 * doc/autoconf.texi (Special Shell Variables): Document
9279 2001-10-31 Akim Demaille <akim@epita.fr>

9286 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not

9289 * configure.ac: Adjust.
9291 2001-10-26 Paul Eggert <eggert@twinsun.com>
9293 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9294 lib/Autom4te/Struct.pm:
9295 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9298 * doc/autoconf.texi (Special Shell Variables): Document some
9299 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9301 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9302 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9303 eval $LINENO is not portable in practice.
9305 2001-10-24 Akim Demaille <akim@epita.fr>
9307 * lib/Autom4te/General.pm (backname): New.
9309 2001-10-24 Akim Demaille <akim@epita.fr>

9319 2001-10-22 Paul Eggert <eggert@twinsun.com>
9321 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9322 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9323 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9324 POSIX decided to standardize on the int flavor of strerror_r.
9325 Always do char* test, as there's no reason not to.
9326 Assign to a char* var, to catch strerror_r that returns int*.
9328 * doc/autoconf.texi (Particular Functions):
9329 Document the above changes. Also, document the fact that
9330 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9332 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9334 2001-10-20 Akim Demaille <akim@epita.fr>
9336 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

9342 unchanged, remove the source.
9343 (&up_to_date_p): Don't be verbose, be debug.

9345 (&autoreconf): Display the full path of the configure.ac we are
9348 Be sure to honor --force with gettextize.
9350 * doc/autoconf.texi: Adjust.
9352 2001-10-20 Akim Demaille <akim@epita.fr>
9354 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9356 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9357 `intl' is already present, as it refuses unless --force.
9358 (&parse_args): Use -I, --include instead of the old Autoconf
9360 ($localdir, $autoconf_dir): Remove.
9362 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9364 2001-10-19 Jens Petersen <petersen@redhat.com>
9366 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9371 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
9372 file in @configure_input@.
9373 Don't mention `automatically' in addition to `generated'.
9374 * tests/torture.at (#define header templates): Adjust.
9376 2001-10-19 Akim Demaille <akim@epita.fr>
9378 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a

9385 configure.ac being studied.
9387 2001-10-18 Paul Eggert <eggert@twinsun.com>
9389 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9390 long, to work around a bug in the HP C compiler version HP92453-01
9393 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9394 (AS_BASENAME_EXPR): New macro.
9395 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9396 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9397 and fall back on 'sed' only if the other two fail. This makes
9398 AS_BASENAME act more like AS_DIRNAME.
9399 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9400 contains white space.
9401 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9402 Use AS_DIRNAME, since I think it's now DOS-friendly.
9403 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9404 Allow "dirname //FOO" to return either / or //, as POSIX allows

9453 (Syntax of the shell scripts): Don't.
9454 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
9455 bother with $force since...
9456 * lib/Autom4te/General.pm: does.
9458 2001-10-08 Akim Demaille <akim@epita.fr>
9460 * bin/autoreconf.in: Rewrite in Perl.
9461 * configure.ac: Adjust.

9530 include handle the m4_pattern_*, no longer push the
9531 BODY diversion nor set the /bin/sh line, AS_INIT does it.
9532 * lib/autotest/general.m4 (AT_INIT): Likewise.
9533 * tests/base.at: Adjust the tests to use AS_INIT.
9534 * tests/tools.at (AT_DATA_FORBIDDEN): New.

9543 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
9544 shell does not support LINENO, and if CONFIG_SHELL is unset or
9545 empty, and if we can find a shell that does support LINENO,
9546 then set CONFIG_SHELL to that shell and then re-execute

9551 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9552 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9553 build of $(TESTSUITE).
9555 2001-10-05 Akim Demaille <akim@epita.fr>
9557 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path
9558 iff we are a bareword.
9559 Reported by Raja R Harinath.
9561 2001-10-05 Akim Demaille <akim@epita.fr>

9594 compatibility with POSIX shells.
9596 2001-10-02 Akim Demaille <akim@epita.fr>
9598 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno

9620 2001-09-30 Paul Eggert <eggert@twinsun.com>
9622 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
9623 Don't use nested parenthesization. This patch was originally
9624 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
9625 but somehow it didn't get incorporated then.
9626 * doc/autoconf.texi (Limitations of Usual Tools):
9627 Clarify remark about sed and nested parenthesization.
9629 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):

9633 Check for `expr' arithmetic overflow, and for compilation failure,
9634 and invoke a new argument $4 if either is discovered.
9635 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9636 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9638 2001-09-28 Akim Demaille <akim@epita.fr>

9649 Output `AT_tested' only when existing.
9650 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
9652 2001-09-27 Akim Demaille <akim@epita.fr>
9654 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
9655 generates too many bug reports.

9658 status when executing the ACTION-IF-FALSE.

9664 (Broken/missing compilers, AC_PROG_CPP with warnings)
9665 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
9666 * tests/c.at (Extensions, C keywords)
9667 (Broken/missing compilers, AC_PROG_CPP with warnings)
9668 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
9669 (AC_PROG_CPP requires AC_PROG_CC): here and...
9670 * tests/fortran.at (GNU Fortran 77): there.
9671 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9672 AC_TRY_RUN is about compilation, not shell commands.
9673 (Test Programs): AC_TRY_RUN works as used to be advertised.
9675 2001-09-27 Akim Demaille <akim@epita.fr>
9677 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9679 Be sure to detect when $LINENO always returns the same value.
9680 Look for the original script, basename($0) is certainly not

9865 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9867 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9868 Do not pass a first argument with leading '-'
9869 to expr, by parenthesizing initial integers that might be negative.
9871 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP

9875 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9876 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9877 whether it is a (compile-time) error to pass an argument to

9895 Add test for AS_BASENAME.
9896 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9897 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9898 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9899 * tests/base.at: Fixed the expected responses. The old ones were
9901 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9902 the documentation claims it should (and how it behaved in 2.13).
9904 2001-09-18 Akim Demaille <akim@epita.fr>
9906 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9907 the AC_CONFIG_COMMANDS invocation.
9908 This also solves the name clash problems.
9909 Don't set the package's ID.

9911 No longer to be shipped.
9912 (version.in): Remove.

9915 Use `m4_PACKAGE_STRING'.
9916 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9917 the only optional argument is the name of the test suite.
9918 Expect `package.m4' to define the package signature.
9919 * lib/autom4te.in (Autotest): Add `package.m4?'.
9920 * tests/Makefile.am (package.m4): New.

9943 fprintf "%d" only after ensuring the argument is of type 'int'.
9944 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9946 2001-09-17 Paul Eggert <eggert@twinsun.com>
9948 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9949 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9950 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9951 when they don't exist.
9953 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9954 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9957 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9958 version with the version used by fileutils 4.1, except use
9959 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

10004 * lib/autotest/general.m4 (AT_INIT): Create and remove
10005 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10006 test suites can cohabit.

10010 * tests/mktests.sh: Don't output banners for empty test files.

10116 2001-09-05 Akim Demaille <akim@epita.fr>

10119 the maintainer is dumb enough to do that...
10121 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10122 excellence in M4 quotation: consider `__file__' is active.
10124 And BTW, when invoking m4, pass the --include in the right order:

10172 2001-08-31 Akim Demaille <akim@epita.fr>
10174 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
10175 serious problems handling heredocs in heredocs.
10176 Reported by Nicolas Joly.
10178 2001-08-31 Akim Demaille <akim@epita.fr>
10180 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.

10183 2001-08-31 Akim Demaille <akim@epita.fr>
10185 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
10187 2001-08-31 Akim Demaille <akim@epita.fr>
10189 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10190 (testsuite Scripts): There is no such thing as `atconfig.in'.
10191 And actually one diagram is missing: test suite runtime.
10193 2001-08-31 Akim Demaille <akim@epita.fr>
10195 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10198 2001-08-31 Akim Demaille <akim@epita.fr>
10200 * bin/autoupdate.in (@include): `installcheck' revealed the path
10201 to m4sugar was lacking!
10203 2001-08-31 Akim Demaille <akim@epita.fr>
10205 * man/Makefile.am (.x.1): We really have to pass
10206 autom4te_perllibdir.
10208 2001-08-31 Akim Demaille <akim@epita.fr>
10210 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

10214 2001-08-31 Akim Demaille <akim@epita.fr>
10216 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10217 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10218 Use directly autom4te, not autoconf.
10219 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
10221 2001-08-31 Akim Demaille <akim@epita.fr>
10223 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

10242 `print $out' doesn't print `$_' but `$out'.
10243 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10244 (autoheader): Pass --force since the test suite goes too fast for
10246 Adjust to the new autoheader messages.
10248 2001-08-31 Akim Demaille <akim@epita.fr>
10250 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

10258 * lib/Autom4te/General.pm (&find_file, &update_file): New.
10259 * bin/autoupdate.in, bin/autoheader.in: Adjust.
10260 Drop AC_MACRODIR dead for real.
10261 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10262 `autoheader: `config.hin' is created'.
10263 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10265 2001-08-31 Akim Demaille <akim@epita.fr>
10267 * bin/autoheader.in: Rewrite in Perl.
10268 * tests/autoheader: Adjust.
10270 2001-08-31 Akim Demaille <akim@epita.fr>
10272 * bin/autoconf.in (--include, -I): New option.
10273 Map --localdir, --autoconf-dir onto it.
10274 Forward autom4te's options instead of interpreting them.
10275 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10276 There is no such envvar since the inception of autom4te.cfg.
10277 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10278 * bin/autoupdate.in: Adjust, and perform more control.
10279 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
10280 * tests/autoconf: Dittowise.
10282 2001-08-31 Akim Demaille <akim@epita.fr>
10284 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10285 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10287 Use -e, not -f, since /dev/null for instance is OK.
10288 (&parse_args): Adjust.
10289 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10291 2001-08-31 Akim Demaille <akim@epita.fr>
10293 * configure.ac: Also find tested executables in bin.
10294 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10295 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10296 installed peer executables, only PATH is allowed to resolve it.
10297 Pass `autoconf_dir' via options, not via invisible envvars.
10298 * lib/Autom4te/General.pm (&find_peer): Remove.
10299 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10300 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10301 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10302 find the executables for it.
10303 * tests/Makefile.am: Major cleanup. Too lazy to document...
10304 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10306 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10307 indeed related to running the test suite, while passing
10308 --autoconf-dir and others is related to running non installed
10309 Autoconf executables. So don't do that, leave it to...
10310 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10311 * tests/autoscan: New.
10312 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10313 refer to library files: rely on --language.

10317 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

10320 2001-08-29 Akim Demaille <akim@epita.fr>
10322 * doc/autoconf.texi: Strip the @nodes.

10326 2001-08-29 Akim Demaille <akim@epita.fr>
10328 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10329 Suggested by Paul Eggert.
10331 2001-08-29 Akim Demaille <akim@epita.fr>
10333 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10334 download in a tmp dir.
10336 2001-08-29 Akim Demaille <akim@epita.fr>
10338 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10339 case insensitive OSes out there :(

10350 * bin/autoconf.in: Simplify and adjust.

10357 * lib/autotest/general.m4: Use
10358 foo=`(command) 2>/dev/null`
10360 foo=`command` 2>/dev/null
10361 (at-devnull): Rename as...
10362 (AT-devnull): this.

10399 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10400 Support `VAR=VAL' as arguments.

10509 the name of the directory they're in, instead of the filename,

10878 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10879 * doc/autoconf.texi (C Compiler Characteristics): Update

10888 2001-08-10 Akim Demaille <akim@epita.fr>
10890 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10892 Suggested by Russ Allbery.
10894 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10896 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10897 current $prefix to the sub-configures.
10899 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10901 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10902 extension (needed on BeOS). Reported by Guido van Rossum.
10904 2001-08-09 Akim Demaille <akim@epita.fr>
10906 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10908 2001-08-07 Akim Demaille <akim@epita.fr>
10910 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10912 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10913 No need to remove the files before and after the each test, before
10914 each test and at the end of the suite is enough.
10915 Display only the children `times', not the shell's.
10916 If the test failed or was skipped, at-times is not available.
10918 2001-08-07 Akim Demaille <akim@epita.fr>
10920 Always produce testsuite.log, including when there are no
10921 failures. This helps getting information on skipped tests, and
10922 duration of the tests. Err, implement the latter btw.
10924 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10925 Dump information on the first run of each test.
10926 (AT_CLEANUP): Create `at-times' containing the duration of the
10929 2001-08-07 Akim Demaille <akim@epita.fr>
10931 The use of `dumpstat' revealed that `len' was used although it
10932 should not. m4_text_wrap was using it, but in the Autoconf world
10933 where it is legal. Hence (i) test M4sh in its own world, not
10934 Autoconf's, and (ii), ahem, fix the bug :)
10936 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10937 does not like `' instead of [].
10938 (AT_INIT): Forbid `^_?AT_'.
10939 And don't output such tokens.
10940 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10941 `script.as', and `autom4te.cache'.
10942 Remove `empty' and `macro' which are no longer used.
10943 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10944 * tests/m4sugar.at: Use it.
10945 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10947 2001-08-07 Akim Demaille <akim@epita.fr>

10953 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10955 2001-08-04 Akim Demaille <akim@epita.fr>
10957 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10958 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10960 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10961 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10962 (AC_F77_MAIN): Likewise.
10964 2001-08-04 Akim Demaille <akim@epita.fr>
10966 Don't rely on M4sugar outputting the patterns in files, since we
10967 might process the output _without_ running m4, hence without these
10970 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10971 * bin/autom4te.in (@Request::includes): Remove, unused.
10972 (@Request::source): Rename as...
10973 (@Request::input): this.
10974 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10975 (&handle_output): Fetch the patterns from the traces.

10977 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10978 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10980 2001-08-04 Akim Demaille <akim@epita.fr>
10982 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10983 autoconf', i.e., in addition to caching traces, cache the output.
10985 * bin/autom4te.in (Request::cache): Rename as...
10986 (Request::id): this.
10987 ($cache, $icache, $tcache, $ocache): New.
10988 (&handle_m4): Save M4 output in the cache instead of $tmp.
10989 (&handle_output): Adjust.
10990 (&up_to_date_p): Check that the output cache is up to date too.
10991 (top level): Run `&handle_m4' iff force or the cache is invalid.

10994 2001-08-04 Akim Demaille <akim@epita.fr>
10996 * bin/autom4te.in ($force): New.
10997 (&parse_args, &print_usage): -f, --force is a new option.
10998 (&handle_output): CPP directives might have spaces after `#'.
10999 (&parse_args): The first file only can be frozen.
11001 2001-08-04 Akim Demaille <akim@epita.fr>
11003 Don't let autom4te compute the `include' traces several times:
11004 first check that the trace cache file is up to date, and then
11005 compare its timestamp with that of the output.
11007 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11008 the preamble. Don't require 5.005 as Autom4te::General does it,
11009 and better yet (use `use', not `require'!).
11010 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11011 Class::Struct as Autom4te::Struct.
11012 * lib/Autom4te/General.pm (File::stat): Use it.
11013 (&mtime): New, export it.
11014 * bin/autom4te.in: Use it.
11015 Declare `$req' is invalid if it is outdated.
11016 Don't declare it valid before saving it if something went wrong.
11018 2001-08-04 Akim Demaille <akim@epita.fr>

11052 (@m4_builtin): this.
11053 (%m4_builtin_alternate_name): New.
11054 (&parse_args): Complete the trace requests with alternate names.

11066 (m4_divert_pop): Dump the whole diversion stack when a diversion
11068 * bin/autom4te.in (&handle_output): Remember of the first
11069 occurrence of a possibly undefined macro, not the last.
11070 Complain about the possibly undefined macros in the same order as
11071 the appear in the output.
11072 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11073 * tests/tools.at (autoconf: forbidden tokens, basic)
11074 (autoconf: forbidden tokens, exceptions): No longer sort
11075 autoconf's stderr, as it is now deterministic.
11076 Check that `dnl' is caught.
11078 2001-08-01 Akim Demaille <akim@epita.fr>
11080 * configure.ac: Bump to 2.52c.
11082 2001-08-01 Akim Demaille <akim@epita.fr>
