82 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
83 7.1.4 /usr/bin/posix/sh described by Tim Rice in

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

464 this and enough programs depend on it so we should check for it.
465 Bruno Haible reports in
466 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
467 that long long int is 32 bits wide with some nonstandard compilers.
468 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
470 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
472 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
473 to a nonexistent file, so that we don't have to worry about
474 a local site configuration that doesn't use /usr/local.
475 Problem reported by Keith Marshall in
476 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
478 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
480 * doc/autoconf.texi: Be more consistent about using @acronym with
481 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
482 quite right (it talked about "OSF/Tru64", even though the
483 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
484 and it even mentioned "OSF 4"!) and at this point there's little
485 reason to talk about OSF any more, since it died in 1994.
486 (Specific Compiler Characteristics): Simplify example of
487 negative-size array.
488 (File Descriptors): Reorder to make the text flow better.
489 Remove joke about "appreciate the various levels"; I didn't get it.
490 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
491 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
492 (File Descriptors, Limitations of Usual Tools):
493 Tone down the advice against renaming or removing open files.
494 (Limitations of Usual Tools): Add a new section, on 'rm'.
496 2006-06-26 Stepan Kasal <kasal@ucw.cz>
498 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
499 -lXt in LIBS, idea from Karsten Hopp; this was due since
500 this change:
502 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
503 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
504 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
505 (which belong to Xt, not X itself). See Debian bug 327655.
507 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
509 * configure.ac (AC_INIT): Bump to 2.60a.
510 * NEWS: Update.
512 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
514 Version 2.60.
516 * configure.ac, NEWS: Update.
518 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
520 * config/texinfo.tex: Sync from upstream.
522 * bin/autom4te.in (handle_traces): Transform the `@S|@'
523 quadrigraph correctly in traces.
525 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
526 Fix typos.
528 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
529 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
530 not defined.
531 * doc/autoconf.texi (Changed Directory Variables): New node,
532 to document the whole `datarootdir' business a bit better.
533 * NEWS: Update.
534 * tests/torture.at (datarootdir workaround): Extend test.
535 Prompted by report by Alexandre Julliard.
537 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
539 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
540 when using default mode of IBM C 6 for AIX. Problem and two-line
541 fix reported by Larry Jones.
543 2006-06-22 Alexandre Julliard <julliard@winehq.org>
545 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
546 about literal '${datarootdir}' if a definition is found in the
547 output file.
549 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
551 * NEWS: Use "M4" rather than "m4" when appropriate.
552 Problem reported by Eric Blake.
553 * doc/autoconf.texi: Likewise.
554 Use @acronym around BSD, GCC, and GNU when appropriate.
555 (Why GNU M4): Renamed from "Why GNU m4".
556 (Redefined M4 Macros): Mention that Posix
557 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
558 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
559 to int.
561 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
563 * bin/autom4te.in (handle_output): Do not forbid the empty
564 pattern.
565 * tests/tools.at (autoconf: the empty token): New test.
567 2006-06-20 Stepan Kasal <kasal@ucw.cz>
569 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
570 calls, so that we do not care whether they are LIFO or FIFO;
571 in the m4_wrap, do not check which diversion is the topmost
572 one, just check that the stack is balanced at the end.
573 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
574 base diversion forever--pop the previous diversion before
575 opening the new one; consequently, remove the m4_wrap call.
576 * lib/autotest/general.m4 (AT_INIT): Likewise.
577 * tests/m4sugar.at: Do not use
578 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
580 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
581 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
583 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
584 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
585 Rework example of m4wrap token-pasting trouble so that it doesn't
586 care whether it's LIFO or FIFO.
587 Fix some "contrary to"s that are awkward in English.
589 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
591 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
592 to `yes' instead of `int$1_t' if the type is found, for more
593 consistent configure output (where $1 is the number of bits).
594 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
595 Suggested by Bruno Haible.
597 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
598 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
599 with system headers. Report by Bruno Haible.
601 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
603 * config/config.guess, config/config.sub: Sync from upstream.
605 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
606 in order to avoid picking up an older installed frozen m4sh.m4f.
607 Besides an outdated shell startup, this could have been created
608 by an earlier M4 version with incompatible frozen file format.
610 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
612 * README: Recommend m4 1.4.4 instead of 1.4.3..
613 * doc/autoconf.texi: Likewise.
614 (Special Chars in Names): Say that $(.FOO) is portable, as
615 suggested by Stepan Kasal.
616 (Installation Directory Variables, Build Directories):
617 (Automatic Remaking, Subdirectories, Fortran Compiler):
618 (Making testsuite Scripts, Defining Directories):
619 Quote variable usages better.
620 (Making testsuite Scripts): Add clean-local rule to makefile
621 snippet, by Eric Blake.
622 (Installation Directory Variables): Fix table item font.
623 Reword slightly to clarify. Generalize advice about
624 not using special characters to include all file-related
625 vars, not just VPATH.
626 (Special Chars in Variables): Warn about special characters in
627 $(srcdir) too.
628 (Assignments): Clarify default-value example as suggested by
629 Ralf Wildenhues in
630 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
631 (Special Shell Variables): Note leading ./ or ../, as suggested
632 by Eric Blake.
633 (Limitations of Builtins): Under cd, warn about CDPATH.
634 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
635 Ralf Wildenhues.
637 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
639 * doc/autoconf.texi (Configuration Actions): Remove duplicate
640 `@var', for texi2html.
641 (Systemology): Some more word wrapping, for DVI output.
642 (autom4te Invocation): The short option for `--melt' is `-M',
643 not `-m'.
645 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
647 * doc/autoconf.texi: More formatting and English tweaks,
648 many suggested by Ralf Wildenhues.
649 Reword to avoid "@code{...}'s" and the like, since it's ugly
650 with Emacs info mode. discontents -> woes.
651 Put a few "will"s back. time stamp -> timestamp.
652 side-effect -> side effect.
654 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
656 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
657 Warn about $@ not persisting. Problem reported by Julien Danjou in
658 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
659 (Special Chars in Names): Renamed from Leading _ in Macro Names.
660 Mention other special chars, too.
662 2006-06-14 Eric Blake <ebb9@byu.net>
664 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
666 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
668 * doc/autoconf.texi: Some systematic minor improvements, as
669 follows. Use "makefile" when talking about makefiles
670 generally (which might be named "makefile" or "Makefile" or even
671 "foo.mk"), "Makefile" when talking about a specific makefile
672 called "Makefile". This unclutters the text from weird quotes
673 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
674 values" rather than "@var{foo}s" and similar constructs containing
675 "}s". Use "Make rules" rather than "Makefile rules". Minor
676 English-language improvements. Change the prefix "sub-" to "sub"
677 and "re-" to "re".
678 Put blank lines around examples more consistently.
679 Avoid "rather" and "very" as intensifiers.
680 Avoid "will" as an auxiliary.
681 (Limitations of Make): Split this node into....
682 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
683 (Leading _ in Macro Names, Backslash-Newline-Newline):
684 (Backslash-Newline Comments, Long Lines in Makefiles):
685 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
686 (obj/ and Make, make -k Status, VPATH and Make):
687 (VPATH and Double-colon, $< in Explicit Rules):
688 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
689 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
690 New nodes, resulting from splitup of Limitations of Make.
691 All cross-references changed. Raise the top node from
692 a section to a chapter, and all subnodes accordingly.
693 Redo the introductory wording to match the new organization.
694 (Installation Directory Variables): Use an example that is
695 closer to what Autoconf actually does. Mention that VPATH's
696 value should not contain metacharacters or white space.
697 (Fortran Compiler): Fix a VPATH bug in an example.
698 (Leading _ in Macro Names): Mention that this problem is no longer
699 of practical concern.
700 (VPATH and Make): Reword the advice to make it clearer
701 that Autoconf and Automake support VPATH in non-GNU make, but
702 many packages have bugs in this area.
703 ($< in Explicit Rules): Refer to Build Directories rather
704 than using a (non-VPATH-safe) example.
705 (Automatic Rule Rewriting): Mention the sort of disaster that
706 can ensue with Solaris-style rule rewriting with VPATH.
708 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
710 * doc/install.texi (Compilers and Options): Weaken the
711 suggestion to use GNU make for VPATH builds.
713 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
714 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
716 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
717 in regular expression.
719 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
721 * doc/autoconf.texi (Installation Directory Variables):
722 Drop extra @samp from `@table @samp' item.
723 (Limitations of Usual Tools): Comment fix.
724 Do not nest @samp just to point to other table items.
725 (Writing testsuite.at) <AT_CHECK>: The second argument to
726 `@dvar' is already @samp'ed.
727 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
728 do not use @var in the second argument.
730 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
732 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
733 $as_shell.exe too. Problem reported by Andreas Buening in
734 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
736 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
738 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
739 `unused variable' compiler warning, for `-Wall -Werror'.
740 Reported by Jaap Haitsma in
741 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
743 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
745 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
746 case the compiler dumps core. Problem reported for
747 OpenServer 5.0.7 by Tim Rice in
748 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
749 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
750 Likewise.
752 2006-06-06 Tim Rice <tim@multitalents.net>.
754 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
755 "ERROR" only shows up in "make check" output if there is an
756 error.
758 2006-06-06 Eric Blake <ebb9@byu.net>
760 * tests/tools.at (automatically allowed tokens): Fix typo.
762 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
764 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
766 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
767 typically overflows on x86 CPUs, even though the C standard
768 requires otherwise.
770 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
772 * configure.ac (AC_INIT): Bump to 2.59e.
773 * NEWS: Update.
775 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
777 Version 2.59d.
779 * config/texinfo.tex: Sync from upstream.
781 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
782 seen, invoke libtoolize with `--ltdl' argument.
783 * lib/autom4te.in (Autoreconf-preselections): Adjust.
784 * NEWS: Update.
785 Suggested by Eric Blake.
787 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
789 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
790 reported by Ralf Wildenhues.
791 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
793 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
795 * THANKS: Update.
797 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

803 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
804 message issued by AC_REQUIRE.
805 * tests/m4sugar.at: Check m4_require's error message.
806 * tests/base.at: Check AC_REQUIRE's error message.
807 * tests/local.at (AT_CHECK_M4): New macro, almost identical
808 to...
809 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
810 AT_CHECK_M4.
811 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
812 `expout' as the last parameter.
813 * tests/tools.at: Adapt to the above change.
815 2006-06-04 Stepan Kasal <kasal@ucw.cz>
817 * doc/autoconf.texi (Limitations of Usual Tools): Correct
818 information about race-free implementations of mkdir.
820 2006-06-04 Eric Blake <ebb9@byu.net>
822 * bin/autoreconf.in (help): Document M4 environment variable.
823 * bin/autoconf.as (Usage): Likewise.
824 * bin/autom4te.in (help): Likewise.
825 * doc/autoconf.texi (autom4te Invocation): Likewise.
827 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
829 * NEWS: GNU make now recommended for VPATH builds.
830 Mention that some macros are now documented to be obsolescent.
831 * doc/autoconf.texi:
832 Prefer "current" to "modern" to describe
833 currently-used (albeit perhaps old-fashioned) hosts.
834 Mention which ancient features no longer need to be worried about.
835 setgid -> set-group-ID
836 setuid -> set-user-ID (these are the Posix terms)
837 Fix some misuses of "only".
838 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
839 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
840 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
841 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
842 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
843 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
844 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
845 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
846 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
847 Mention that these macros are obsolescent.
848 (Installation Directory Variables): shall -> should
849 (File Descriptors): Mention that 0, 1, 2 might get reopened.
850 Mention that it's now safe to use 3 and 4.
851 (Limitations of Usual Tools): cp -r is now specified by Posix.
852 Omit longwinded and obsolescent discussion of cp -f.
853 Modernize discussion of expr, ls.
854 (Limitations of Make): Modernize discussion of VPATH builds.
855 Mention $? as a workaround in some cases.
856 * doc/install.texi (Basic Installation):
857 Mention "./configure; make; make install" first. Be more
858 specific about why this file is generic. Remove unnecessary
859 parens. Remove misleading "only". Remove obsolete advice
860 about csh. Don't say "configure" takes awhile; say it
861 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
862 and CC=c99 rather than CC=c89, as these are blessed by current
863 Posix. Recommend GNU make if doing a VPATH build.
865 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
867 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
868 examples involving shell prompts.
870 2006-06-02 Stepan Kasal <kasal@ucw.cz>
871 and Paul Eggert <eggert@cs.ucla.edu>
873 * doc/autoconf.texi (Here-Documents): Add details about the
874 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
875 use "here-documents" instead of "here documents".
877 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
879 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
881 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
883 * doc/autoconf.texi (File System Conventions): Warn about ":"
884 anywhere in directory names.
886 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
888 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
889 about quoting the case statement, just in case.
890 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
891 was fixed in ksh93g; reported by Ralf Wildenhues.
893 2006-05-31 Stepan Kasal <kasal@ucw.cz>
895 * doc/autoconf.texi (System Services): Do not document
896 overriding EXEEXT via ac_cv_exeext=ext.
897 (Particular Programs) <AC_PROG_MKDIR_P>:
898 Document that ${MKDIR_P} understands --.
899 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
900 comment.
902 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
904 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
905 argument with leading hyphen. Problem reported by Paul Eggert.
907 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
909 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
910 about quoting ac_try: quote all of it, if any of it seems suspicious.
911 This means we don't have to worry about ${ or sed any more.
912 Also, double-quote the case statement, to work around misuses via
913 underquoting as reported by Ralf Wildenhues in
914 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
915 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
916 undocumented and dangerous macro.
917 Problem reported by Ralf Wildenhues in
918 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
920 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
922 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
923 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
924 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
926 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
928 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
929 since evidently some packages rely on the old, broken behavior.
930 Problem reported by Ralf Wildenhues in
931 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
932 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
933 pre-2006-05-26 definitions, but leave in the comments that
934 these macros are dangerous and should not be used.
935 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
936 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
937 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
938 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
939 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
941 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
943 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
944 the use of 'tr', since this is our only use of 'tr'.
946 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
947 and Paul Eggert <eggert@cs.ucla.edu>
949 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
950 Don't assume 'grep' works on long lines, since AIX grep doesn't.
952 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
954 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
955 the output file in the `${datarootdir}' test.
957 2005-05-28 Stepan Kasal <kasal@ucw.cz>
958 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
960 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
961 mention of `datarootdir' in the input file(s), but literal
962 `${datarootdir}' in the output file, and we haven't warned yet,
963 then warn as well: the user may have (erroneously) used
964 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
965 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
966 * tests/torture.at (datarootdir workaround): Extend this test.
967 * NEWS: Update.
969 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
970 and Paul Eggert <eggert@cs.ucla.edu>
972 * doc/autoconf.texi (autoheader Invocation): The first argument to
973 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
974 alternatives and clear up the language a bit.
976 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
978 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
979 ac_config_guess, ac_config_sub, ac_configure.
980 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
981 Fix typo that prevented an unnecessary space from being removed.
982 Problems reported by Ralf Wildenhues in:
983 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
985 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
987 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
988 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
989 Don't use the term "thread-safe" to talk about mkdir race
990 conditions, since the problem is more a process than a thread
991 issue. Problem reported by Stepan Kasal in:
992 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
993 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
994 the test for 'install' more closely. Look at MKDIR_P first.
995 Look in the PATH, and at /opt/sfw/bin.
996 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
997 Don't bother to try mkdir -p, since we already check mkdir --version;
998 just look at the version number. (There's no easy way to check
999 for race-free implementations.)
1000 * tests/tools.at (autoconf: subdirectories): Adjust to above
1001 changes, since MKDIR_P now might end in "/mkdir -p".
1003 * doc/autoconf.texi (autoheader Invocation): Mention that the
1004 first arg of AC_DEFINE_UNQUOTED must be a literal.
1005 Problem reported by Ben Pfaff in
1006 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1008 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1009 * doc/autoconf.texi (Special Chars in Variables): New section.
1010 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1011 (Installation Directory Variables): Quote $(datadir) better.
1012 (Limitations of Builtins): Describe some of eval's trickiness.
1014 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1015 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1016 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1017 in front of every arg, not just trailing args. Quote apostrophes.
1018 (_AC_EVAL_ECHO): New macro.
1019 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1020 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1021 removed.
1022 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1023 exposed by quoting of eval argument. Put the command on line line
1024 so it logs better.
1025 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1026 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1027 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1028 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1029 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1030 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1031 Use eval more safely.
1032 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1033 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1034 to be replaced.
1035 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1036 lines, exposed by quoting of eval argument.
1038 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1039 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1041 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1042 initialization of `ac_cv_exeext', do not override it if it was
1043 already set, unless it was set to `no', for compatibility with
1044 Autoconf-2.13, and comment this.
1045 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1046 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1047 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1048 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1049 Document that this test may be overridden by setting
1050 `ac_cv_exeext'.
1052 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1054 Revert these two patches:
1056 2006-04-06 Eric Blake <ebb9@byu.net>
1057 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1058 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1059 2006-04-01.
1061 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1062 Clean up _AC_COMPILER_EXEEXT* macros.
1063 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1064 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1065 ac_file to the name of the default output file and call
1066 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1067 initial `rm' of the candidate files...
1068 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1069 the same list in subsequent `rm' calls, and for the temporary
1070 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1071 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1072 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1073 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1074 no longer needed) by libtool. Make it a cache check.
1075 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1076 copied here by mistake.
1077 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1078 _AC_COMPILER_EXEEXT.
1079 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1080 _AC_COMPILER_OBJEXT directly.
1081 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1083 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1085 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1086 Fix description of how the buggy `sed' works.
1088 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1090 Sync from Automake:
1092 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1093 ENOLCK. Only mention `make -j' when applicable. Only raise
1094 fatal errors when `make -j' is involved. Improve error message.
1096 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1098 * doc/autoconf.texi (Here-Documents): We now know more about
1099 the variable expansion in here documents bug.
1100 Thanks to Tim Rice and Stepan Kasal.
1102 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1103 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1105 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1107 * tests/autotest.at (Multiline command from M4 expansion):
1108 No failure to be expected if the shell quotes newlines in
1109 commands in the `set -x' output. Report by Tim Rice.
1110 * THANKS: Update.
1112 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1114 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1115 expansion in the here-documents used by config.status, as that
1116 runs afoul of the Korn shell version M-12/28/93d bug described in
1117 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1118 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1119 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1121 2006-05-23 Jim Meyering <jim@meyering.net>
1123 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1124 Fix typo introduced with 2006-04-02 change. It reversed the sense
1125 of the test.
1127 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1129 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1130 ac_dB slightly, to save bytes in the script.
1131 Max out at 50 lines, rather than 96; this is more likely
1132 (though not guaranteed) to avoid obscure 'sed' failures.
1134 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1136 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1137 `tr -d -' as bad option argument. Work around this by deleting
1138 an unrelated character.
1139 Report by Tim Rice <tim@multitalents.net>.
1141 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1142 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1143 Stepan Kasal <kasal@ucw.cz>
1145 * doc/autoconf.texi (Particular Programs): Do not promise that
1146 we always prefer the GNU version of the program, and that we
1147 search according to PATH; both rules can have exceptions.
1148 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1149 AC_PROG_SED. Move descriptions of limitations
1150 to the Limitations of Usual Tools section.
1151 (Limitations of Usual Tools) <sed>: Mention script length
1152 limitations with Solaris /usr/ucb/sed.
1153 <grep>: Fix wording for empty alternative. Mention that -c and
1154 -l should not be combined, and that -E and -F should not be
1155 combined.
1157 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1158 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1160 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1161 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1163 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1165 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1166 AC_DEFINE is now passed to m4_pattern_allow.
1167 * NEWS: Mention that; likewise for AC_SUBST.
1168 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1169 the parameter to m4_pattern_allow.
1170 * tests/tools.at: Add a check for that.
1172 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1174 * lib/autoconf/status.m4: Fix typos.
1176 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1178 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1179 only the files that this macro generates.
1181 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1183 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1184 the HP-UX sed limitation of 99 commands, labels do not count.
1185 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1186 in the comment.
1187 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1189 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1191 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1192 Import the following fix from coreutils:
1194 2006-01-13 Jim Meyering <jim@meyering.net>
1196 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1197 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1198 not double-quote uses of that variable, to accommodate the rare
1199 case in which getmntent is available in none of the libraries
1200 checked. This happens at least on FreeBSD 5.0.
1202 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1204 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1205 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1206 some other programs unwisely rely on these undocumented vars.
1207 But put in warning comments about them.
1208 Problem reported by Ralf Wildenhues in
1209 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1210 * NEWS: Document that these variables are intended to go away.
1212 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1214 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1215 and set the language to C++ (analogous to the equivalent Fortran
1216 tests).
1218 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1219 * doc/autoconf.texi (C++ Compiler): Document it.
1220 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1221 * NEWS: Update.
1223 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1225 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1226 that caused config.status to generate 100-command sed scripts; the
1227 portable limit is 99.
1229 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1231 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1232 variable `ac_d' instead of `d' to avoid infringing namespace.
1233 Report by Ralf Menzel.
1235 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1237 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1238 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1239 * tests/tools.at (autoconf: subdirectories): New test, taken from
1240 the corresponding problem report by Ralf Wildenhues in:
1241 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1243 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1244 Quote some uses of shell variables if they might suffer unexpected
1245 globbing. This doesn't fix all instances of quoting problems that
1246 I found, just the easy ones that look safe.
1247 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1248 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1249 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1250 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1251 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1252 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
1253 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
1254 Likewise.
1255 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
1256 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1258 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1260 * bin/autoreconf.in ($help): Reword according to the manual.
1261 Suggested by Olly Betts.
1263 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1264 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1266 * bin/autoreconf.in: Pass the directory argument to
1267 `require_configure_ac'. Fix comment.
1268 * tests/torture.at (Configuring subdirectories): Expose this.
1269 Reported by Olly Betts.
1271 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1273 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1274 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1275 Automake as follows:
1277 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1278 `$configure_in' instead of `configure.in', to preserve
1279 directory component.
1281 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1283 * config/config.guess, config/config.sub, config/texinfo.tex,
1284 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1286 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1288 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1289 test for C99 conformance; (bool) 0.5 is an integer constant
1290 expression, but (bool) -0.5 is not. Problem reported by Fedor
1291 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1293 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1295 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1296 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1297 Warn about obsolete install-sh files. Remove stray sentence
1298 fragment and fix cross reference.
1299 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1300 install -d; this undoes the 2006-05-10 change.
1301 (MKDIR_P): Mark with AN_MAKEVAR.
1302 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1303 that we don't require $INSTALL to be thread-safe. Move comments
1304 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1305 of AC_PROG_INSTALL. Output a message saying that we're checking
1306 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1307 MKDIR_P instead of AC_SUBST.
1308 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1309 Special magic for MKDIR_P, too.
1310 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1311 a dnl.
1312 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1314 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1316 Sync from Automake, as follows:
1318 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1319 * config/install-sh: Initialize IFS, so field splitting isn't
1320 turned off later.
1321 * config/mkinstalldirs: Likewise.
1322 * config/missing: Remove superfluous quotes. Replace all uses of
1323 `[' by `test', for consistency, and for..
1324 * config/missing (sed_minuso, sed_output): New variables.
1325 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1326 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1327 Fixes `missing' to detect `--output' for help2man. Fixes
1328 PR automake/483. Report by Dennis J. Linse.
1329 (autom4te): Document in `missing --help'.
1331 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1333 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1334 * config/install-sh: Don't use 'path' to talk about file names,
1335 as per GNU coding standards. Close a race condition reported by Ralf
1336 Wildenhues and Stepan Kasal. There is still a race condition
1337 on hosts that predate Posix 1003.1-1992, but we can't help this.
1338 Don't mishandle weird characters like space on pre-Posix hosts.
1339 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1340 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1341 AC_PROG_MKDIR_P from AS_MKDIR_P.
1342 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1343 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1344 earlier editions are not (including Automake 1.8.3).
1345 Do not suggest mkinstalldirs for thread-safety.
1346 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1347 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1348 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1349 presence of special characters and race conditions.
1350 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1351 in Autoconf's name space.
1353 2006-05-10 Bruno Haible <bruno@clisp.org>
1354 and Paul Eggert <eggert@cs.ucla.edu>
1356 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1357 from Automake with minor changes.
1358 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1360 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1362 * config/install-sh: Update to Automake CVS version, as follows:
1363 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1364 * lib/install-sh: Simplify the expr implementation of dirname.
1365 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1366 * lib/install-sh: Handle --, and diagnose unknown options.
1368 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1370 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1371 `./autom4te' to create `./testsuite', since the `all' target
1372 will ensure its presence, but `installcheck' should not create
1373 the uninstalled wrappers.
1375 * tests/torture.at (Unusual Automake input files): Skip if we
1376 detect automake < 1.8.
1378 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1380 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1381 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1382 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1383 * NEWS: Update.
1385 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1387 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1388 munge (multiple) white space and other oddities.
1389 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1390 single quotes in variable assignment.
1391 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1392 and similar failures by adding multiple spaces, tabs, and other
1393 special characters.
1394 Report and different test suggested by Francesco Romani
1395 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1397 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1398 single quotes, we only need to search for single quotes; this
1399 both simplifies the search pattern, and makes us less
1400 susceptible to `echo' variations for arguments not containing
1401 single quotes.
1402 (_AC_ARG_VAR_VALIDATE): Likewise.
1404 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1406 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1407 `$*' and IFS concatenation issue with traditional shells and
1408 bash-2.04. Report by Seanster@Seanster.com.

1412 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1413 precisely which Mac OS X versions have the od problem.
1415 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1417 * doc/autoconf.texi: Use @option systematically.
1419 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1420 and Bruno Haible <bruno@clisp.org>
1422 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1423 about 'od'.
1424 (Integer Overflow): Mention the special case of integer division
1425 overflow.
1427 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1429 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1430 traditional shells like the Solaris one that do not use the
1431 first IFS character for assembling `$*'.
1432 Prompted by a related report from autoconf_bug@nro.ca.
1434 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1435 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1437 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1438 Mention more problems with the -e option.
1440 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1442 * NEWS: Typo.
1443 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1445 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1446 in URLs to improve DVI formatted output (requires texinfo 4.6).
1447 (System Services, Systemology, Shellology): Likewise.
1448 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1449 output.
1451 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1452 continuous text.
1453 (Runtime): Fix macro argument names to match description:
1454 `action-if-found' -> `action-if-true' and similarly.
1455 (Obsolete Macros): Likewise.
1456 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1457 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1458 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1460 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1462 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1464 * ChangeLog: Typo.
1465 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1466 DVI output.

1478 (Integer Overflow, Null Pointers, Buffer Overruns):
1479 (Floating Point Portability, Exiting Portably): New sections.
1480 (Writing Test Programs): Fix some langauge. Recommend exiting
1481 with status 1, not merely nonzero. Clarify exit declaration.
1482 (Run Time): Move C exit status stuff to new Exiting Portably section.
1483 (Systemology): Mention Posix and levenez. Update v7 reference.
1484 (Portable Shell): Mention the Posix shell.
1486 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1488 * bin/autoconf.as (me): Replace by as_me.
1490 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1492 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1493 since as_me isn't set yet.
1495 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1497 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1498 a few minor bugs in this area.
1500 * doc/autoconf.texi (Programming in M4sh): Comment out the
1501 documentation of AS_BASENAME, for now.
1502 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1503 (Limitations of Builtins) <basename>: Do not refer to
1504 AS_BASENAME.
1505 * bin/autoconf.as (me): Don't use AS_BASENAME.
1506 (dir): Remove the unused variable.
1507 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1508 AS_DETECT_REQUIRED. All uses changed.

1510 All uses changed.
1511 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1512 (AS_BASENAME): Use "basename --" to protect against leading "-".
1513 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1514 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1515 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1516 (_AS_DIRNAME_PREPARE): Likewise.
1517 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1518 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1519 (AS_DIRNAME): Use "dirname --".
1521 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1523 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1524 of "run time" and "run-time" changed to "runtime", for consistency.
1525 * lib/autoconf/fortran.m4: Likewise (in comment).
1526 * lib/autoconf/functions.m4: Likewise.
1527 * lib/autoconf/general.m4: Likewise.
1528 * lib/autoconf/headers.m4: Likewise.
1530 * doc/autoconf.texi (Run Time): Document the exit status situation
1531 with more accuracy and detail.
1533 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1535 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1536 Archive is not officially `GNU' any more. Update URL.
1537 (Defining Directories): Likewise
1538 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1540 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1542 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1543 newline from the `trap' code to finish `config.log'; the NetBSD
1544 /bin/sh resets the exit status after an empty command, as
1545 documented in doc/autoconf.texi.
1546 Reported by Dalibor Topic <robilad@kaffe.org>.
1548 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1550 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1551 Suggested by Bruno Haible.
1553 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1555 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1556 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1557 Instead, just list the shells that we know work.
1558 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1559 changed. Be more cautious about the _cv_ variable.
1560 * tests/tools.at (Syntax of the shell scripts): Check the
1561 _cv_ variable once, at first, to avoid an internal autoconf error
1562 when sh -n does not work.
1564 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1566 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1568 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1570 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1571 use ">&-" since we're only 99.999% sure that this is portable,
1572 and since the MinGW bug is fixed in a different way.
1573 * lib/autotest/general.m4 (AT_INIT): Likewise.
1575 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1577 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1578 before opening config.log, to avoid hitting a bug on MinGW.
1580 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1582 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1583 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1584 This works around a MinGW bug reported by Eric Paire.
1585 Make sure that all writes to the log file append to it,
1586 rather than possibly losing data.
1587 * lib/autotest/general.m4 (AT_INIT): Likewise.
1589 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1591 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1592 description.
1594 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1596 * NEWS: Update.
1598 * configure.ac (AC_INIT): Bump to 2.59d.
1600 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1602 Version 2.59c.
1604 * Makefile.maint (news-date-check): Do not require a leading `*'
1605 before the release date in NEWS.
1607 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1608 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1610 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1611 the instantiated file do not contain the string 'datarootdir'
1612 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1613 @mandir@, replace the reference '${datarootdir}' by the value.
1614 * tests/torture.at (datarootdir workaround): New test.
1615 * NEWS: Advertise this temporary fixup.
1616 Based on a patch by Bruno Haible, reported and analyzed by
1617 Paul Eggert and Noah Misch.
1619 2006-04-12 Eric Blake <ebb9@byu.net>
1621 * tests/autotest.at (Debugging a failed test): Fix comment.
1623 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1625 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1626 all the changes since 2006-04-07.
1628 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1630 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1631 succeeded, but `ln -s file dir' failed, take care to remove the
1632 leftover target before the next test, to prevent its spurious
1633 failure; also make sure `ln file dir' works before selecting it.
1634 Thanks to Keith Marshall for pointing this out.
1635 * THANKS: Update.
1637 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1638 assignments in `at_debug_args', so that we put them correctly
1639 in the `run' script.
1640 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1641 Reported by Eric Blake.
1643 2006-04-11 Eric Blake <ebb9@byu.net>
1645 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1646 top-level tests after micro-suite has been run. Used in...
1647 (Debugging a successful test, Debugging script and environment),
1648 (Debugging a failed test): ...these new tests. The first of these
1649 is fixed by...
1650 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1651 macro, split out from...
1652 (AT_INIT): ...here, so that using -d also generates a run script.
1653 Document that -d inhibits top-level logging.
1654 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1655 inhibits top-level logging; debug scripts are created.
1657 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1658 check.
1659 * tests/autotest.at (Empty test, Empty check): New test to check it.
1661 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1662 from gcc.
1664 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1666 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1667 the files if a problem appears. Make the empty *.at files
1668 read-only, too. Proposed by Ralf Wildenhues.
1670 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1672 * config/Makefile.am: Add comment to force updated Makefile.in.
1674 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1675 space only patch to this file, this patch causes the Makefile.in
1676 files that include freeze.mk to be updated, and thus have a
1677 newer time stamp again, which in turn makes a pristine CVS
1678 checkout have correct time stamps.
1680 * Makefile.maint (cvs-sv): New macro, to be used..
1681 (config.guess-url_prefix, config.sub-url_prefix)
1682 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1683 point to CVS text checkout of Gnulib files.
1684 (copyright-check): Bump current year.
1685 (announcement): Do not hard-wire `./announce-gen'.
1686 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1687 correctly.
1688 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1689 `chmod +x'.
1690 (wget_files): Update config.guess, config.sub, texinfo.tex by
1691 `wget-update', now that their URLs work again.
1693 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1695 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1696 Problem noted by Paul D. Smith.
1698 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1700 * doc/autoconf.texi: Remove unused words from word list.
1701 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1702 .x-sc_trailing_space: New files.
1704 * doc/standards.texi: Sync from gnulib.
1706 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1707 `LIBOBJDIR' as experimental.
1709 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1710 with a target directory; it's internally implemented as `cp'
1711 anyway, but since Autoconf advertises the possibility to use
1712 a target directory when LN_S is `ln -s', we need to find out.
1713 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1714 analyzed by Keith Marshall <keith.marshall@total.com>.
1716 * THANKS: Update.
1718 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1720 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1721 confdefs.h as-is. In general, if it has backslash-newline or the
1722 like, then it doesn't work either to sort or to remove empty
1723 lines.
1725 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1727 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1729 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1731 * lib/autom4te.in (Automake-preselections): Preselect
1732 _AM_SUBST_NOTMAKE.
1734 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1736 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1737 apostrophe within a single-quoted string, as this is the usual
1738 tradition and is easier to read than '"'"'. Don't rely on the
1739 shell treating "$/" like '$/'. Use a more-consistent indenting
1740 style for the trap.
1742 2006-04-09 Eric Blake <ebb9@byu.net>
1744 * tests/autotest.at (Backquote command substitution),
1745 (Multiline backquote command substitution): Remove mistaken
1746 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1747 applied...
1748 (Parenthetical command substitution, Multiline parenthetical
1749 command substitution): here.
1751 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1753 Import macros from gnulib (often changing their name).
1755 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

1767 (Pointers): Add Gnulib URL.
1768 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
1769 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1770 Gnulib section.
1771 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
1772 suggest a #define rather than a typedef for _Bool, and mention
1773 Gnulib rather than trying to substitute stdbool code.
1774 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
1775 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
1776 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
1777 AC_STRUCT_DIRENT_D_TYPE.
1778 (Particular Types): Mention stdint.h and inttypes.h as standard
1779 headers too.
1780 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1781 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1782 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1783 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1784 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1785 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1786 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1787 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1788 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1789 (Coding Style). Don't mention m4_expand_once.
1790 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
1791 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
1792 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
1793 (AC_CHECK_FUNCS): Use it.
1794 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
1795 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".

1797 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
1798 (AC_HEADER_ASSERT): New macro.
1799 (AC_HEADER_STDBOOL): Don't assume "#error" works.
1800 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
1801 Catch a bug in an HP-UX C compiler.
1802 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
1803 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
1804 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
1805 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
1806 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):

1826 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1828 Revert the patch from 2006-04-01 and only improve
1829 _AS_DETECT_BETTER_SHELL:
1831 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1832 skip nonexistent directories.
1833 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1834 only shell candidates which exist.
1835 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1836 * lib/autotest/general.m4 (AT_INIT): No need to give three
1837 parameters to _AS_PATH_WALK.
1839 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1840 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1842 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1843 distinguish m4sugar macros.
1844 * tests/tools.at (autoupdating with aclocal and m4_include):
1845 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1846 test case by Noah Misch <noah@cs.caltech.edu>.
1848 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1850 Revert my change from 2006-03-17, in other words:
1851 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1852 and DUALCASE=1.
1853 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1854 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1855 it is set.
1857 2006-04-07 Eric Blake <ebb9@byu.net>
1859 * doc/autoconf.texi (Programming in M4sh): Document that
1860 AS_MKDIR_P exits the script on failure.
1861 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1863 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1865 * config/elisp-comp, config/install-sh, config/mdate-sh,
1866 config/missing, config/mkinstalldirs: Sync from Automake.
1868 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
1869 from Automake.
1871 * doc/make-stds.texi: Sync from gnulib.

1882 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1884 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1885 whether `set' quotes correctly: redirect stderr of the tested
1886 `set', and use a subshell, for Ultrix; use `sed' instead of
1887 `grep' for zsh `set' which may write binary output; match only
1888 at the beginning of a line, to avoid false positives.
1889 In order to avoid false positives by unrelated variables with
1890 multiline content, put the dump algorithm in a subshell and
1891 unset all variables containing newlines (except some which are
1892 special to the shell). Warn about cache variables that are
1893 unset.
1895 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1906 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1907 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1908 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1909 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1911 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1912 shell issue with double-quoted command substitutions of native
1913 commands.

1934 * tests/Makefile.am (maintainer-check-posix):
1935 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1937 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1938 ac_config_<foo>s again, sometimes normalized, sometimes not.
1939 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1940 (AC_CONFIG_COMMANDS): Do not do so here.
1941 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1942 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1943 2005-07-25 rewrite. Noticed by Noah Misch.
1945 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1946 _AC_PRESERVE_HELP_ORDER, ...
1947 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1949 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1950 inside m4_expand_once; it is redundant.
1952 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1953 for --help from Cygnus `configure.'
1955 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

1994 TAGS to ac_config_<foo>s.
1995 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1996 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1997 normalizing it, consistent it with previous releases.
1998 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
2000 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2002 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):

2005 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
2007 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
2008 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
2009 Use 'comm' rather than N instances of grep; this also fixes a bug
2010 whereby substrings were incorrectly matched, causing us to not
2011 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2012 (exclude_list): Exclude empty macros.
2013 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
2015 Use awk rather than grep -E or egrep, to avoid

2018 Switch from grep to awk syntax.
2019 (ac_exclude_script): Renamed from ac_exclude_egrep.
2020 (au_exclude_script): Renamed from au_exclude_egrep.
2022 2006-04-04 Noah Misch <noah@cs.caltech.edu>
2024 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
2025 a subdirectory subject to Cygnus `configure'.
2026 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
2028 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
2029 report request when we have no AC_PACKAGE_BUGREPORT.

2039 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
2040 typedef'ed restricted pointer, to catch a compiler bug on
2041 HP-UX 11.x, and fix warnings so it passes with -Werror.
2042 (_AC_PROG_CC_C99): Likewise.
2043 Reported by Albert Chin <china@thewrittenword.com>.

2094 Clean up _AC_COMPILER_EXEEXT* macros.
2096 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2097 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2098 ac_file to the name of the default output file and call
2099 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2100 initial `rm' of the candidate files...
2101 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2102 the same list in subsequent `rm' calls, and for the temporary
2103 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2104 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2105 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2106 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2107 no longer needed) by libtool. Make it a cache check.
2108 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2109 copied here by mistake.
2110 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2111 _AC_COMPILER_EXEEXT.
2112 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

2145 Autoconf version number despite a zero- or one-argument AC_INIT.
2147 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
2148 subordinate tools.
2149 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
2150 * doc/autoconf.texi (autoreconf Invocation): Document it.
2152 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

2164 the correct lines of the input file by subtracting..
2165 (_au__first_line): ..this new definition.
2167 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
2168 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
2169 Remove stray newline in output.
2170 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
2171 AC_DEFUN this for autoconf, including the obsoletion diagnose.

2173 m4sugar macros.
2174 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.

2178 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
2179 hairy details.
2180 The AC_LANG_SAVE issue was reported against Libtool by
2181 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
2182 Kristian Kvilekval <kris@cs.ucsb.edu>.
2184 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2186 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
2187 switch all of them on and of when necessary. Fixes the bug when
2188 m4sugar macros (e.g., m4_define) were expanded after the first
2189 automatic update (e.g., after AC_PREREQ or AC_INIT).
2191 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

2216 aclocal cannot be given on the command line.
2218 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
2220 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
2221 Give an example for AS_DIRNAME instead of referring to Posix..
2222 (File System Conventions): Put discussion of // versus / here, and
2223 modernize it a bit.
2224 (Limitations of Usual Tools): Add basename. Remove verbiage
2225 after dirname, since it got moved to the above sections.
2226 All this was inspired by a patch proposed earlier by Eric Blake.
2228 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2234 `$0', $as_me.
2236 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2238 * bin/autoscan.in: The value of find_configure_ac should be
2239 checked for existence, so we don't barf over a nonexisting
2240 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
2242 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2244 * bin/autoupdate.in: Fix some typos.
2246 2006-03-21 Stepan Kasal <kasal@ucw.cz>
2248 * doc/autoconf.texi (Installation Directory Variables): Fix typo.
2250 * lib/autoscan/autoscan.list: Refreshed.

2737 (Particular Programs): Likewise.
2738 (Coding Style): y is like s with respect to / and ,.
2739 (Limitations of Usual Tools): Document the weird restrictions
2740 that Posix has about { }. Use better quoting.

2763 2005-12-31 Stepan Kasal <kasal@ucw.cz>
2765 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
2766 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
2768 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
2770 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced

2804 CONFIG_SHELL in the environment of the configure rerun.
2805 * doc/autoconf.texi (Here-Documents, config.status Invocation):

2828 Factor functionality to..
2829 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
2830 `AC_SUBST($1)' in the public version.
2831 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
2832 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
2833 ac_pt_* variables.

2855 2005-10-24 Stepan Kasal <kasal@ucw.cz>
2857 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
2858 conftest.o, to see whether the compiler really obeys; rm the object
2859 file before and after the test and register it with ac_clean_files.
2860 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2862 2005-10-21 Stepan Kasal <kasal@ucw.cz>
2864 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
2865 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the

2882 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
2883 AC_LANG_PROGRAM, fixing a typo. Don't give details about
2884 the inner workings of AC_LANG_FUNC_LINK_TRY.
2885 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2886 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2887 by the function rather than ignoring it.
2888 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2889 comparing its address. Intel's interprocedural optimization was
2890 outsmarting the old heuristic. Problem reported by
2891 Mikulas Patocka.
2893 2005-10-19 Stepan Kasal <kasal@ucw.cz>
2895 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
2897 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
2899 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

2902 2005-10-04 Stepan Kasal <kasal@ucw.cz>
2904 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
2905 before removing it (chmod -R u+rwx); there are three instances of this.
2907 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2908 Stepan Kasal <kasal@ucw.cz>
2910 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2911 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2912 make its content writable before removing it. Remove an errorneous
2913 comment from the end, where the logs of the failed tests are copied
2914 to the main log file.
2916 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2918 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
2919 in case the computer is too quick. Double quote the configure.ac
2920 snippets.
2922 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
2923 problems if the testsuite were running too fast.
2925 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2927 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2928 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2929 (which belong to Xt, not X itself). See Debian bug 327655.
2930 * NEWS: Mention this.
2932 2005-09-07 Stepan Kasal <kasal@ucw.cz>
2934 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
2936 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
2938 * config/move-if-change: Don't output "$2 is unchanged";
2939 suggested by Ben Elliston. Handle weird characters correctly.
2941 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2943 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2944 calls, so that the final expansion of this macro is shorter.
2945 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2946 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2947 the cleanup there. Use AS_VAR_* macros, to be more general.
2948 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2950 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2952 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2954 2005-09-01 Stepan Kasal <kasal@ucw.cz>
2956 * doc/autoconf.texi (Configuration Headers): Add an index entry
2957 for AH_HEADER.
2959 2005-08-26 Pavel Roskin <proski@gnu.org>
2961 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
2962 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
2963 running xmkmf.
2965 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2967 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2968 The previous patch didn't work, so try a better one.
2970 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2972 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2973 in the example. Reported by Bruno Haible.
2974 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2975 "if $undefined_var;" succeeds with my shell.
2977 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2978 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2979 but change the m4_divert_text to m4_divert_once.
2981 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2983 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2984 Work around bug in Solaris /usr/xpg4/bin/awk.
2985 The bug is present in at least Solaris 8 through 10.
2987 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2989 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2990 some evil values and relying on the fact that $* concatenates the
2991 parameters by the first character from IFS.
2993 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2994 Stepan Kasal <kasal@ucw.cz>
2996 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2997 first header appears, define AH_HEADER.
2998 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2999 Update limitations about when to call AC_CONFIG_HEADERS.
3000 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3001 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3002 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3003 ``Configuration Actions''; fix their index entries.
3005 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3006 options correctly. Process N-M as M-N if M is smaller than N.
3007 Process ranges correctly so that N-N will run only N.
3008 Sort and uniquify the tests that will be run. If there is more
3009 than one test, reinsert the banners for the tests.
3010 * tests/autotest.at (Keywords): Unmark XFAIL.
3012 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3014 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3015 before passing the macro name to AH_TEMPLATE.
3017 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3018 now opens log after option processing; in particular, --version
3019 and --help do not touch config.log.
3021 * Makefile.maint: Revert the change from 2005-08-12.
3023 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3025 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3026 common code to...
3027 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
3029 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3031 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3032 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3033 Language cleanup.
3035 * doc/autoconf.texi (Defining Symbols, Changed Results):
3036 Prepend to LIBS, not append, in examples.
3038 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3040 When building in place, set srcdir="."; suggested by Tim Van Holder.
3042 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3043 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3044 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3045 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3046 does not mean "no --srcdir option".
3048 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3050 * tests/autoscan.at (autoscan): New file.
3051 * tests/suite.at: Use it.
3052 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3053 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3055 * tests/autotest.at (Keywords): Test keywords combinations.
3057 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3059 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3060 add "2>&1"; gzip 1.2.4 prints help on stderr.
3062 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3064 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3065 was pushdef'ed twice while popped only once. Push it only once.
3066 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3068 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3070 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
3071 prefixed by mere "===", not "configure: === ".
3073 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
3075 * Makefile.maint: Update from Bison.
3077 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3078 "<tab>" in comment, so that the point is understandable.
3080 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3082 Rewrite substantial part of lib/autoconf/status.m4.
3083 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3084 and CONFIG_COMMANDS are not processed in four separate loops.
3085 Instead, there is one main loop. This alows that the common code
3086 is expanded only once, thus config.status (and configure) is smaller.
3088 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3089 the AC_LIST_FILES and cousins macros are no longer used.
3091 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3092 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3093 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3094 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3095 contain the initialization, nor the for loop, nor the associated
3096 commands; all these go to ...
3097 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3098 _AC_OUTPUT_CONFIG_STATUS.
3099 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3100 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3101 (_AC_OUTPUT_FILE): The creation of the sed script ...
3102 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3103 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3104 _AC_OUTPUT_MAIN_LOOP.
3105 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3106 _AC_CONFIG_COMMANDS): Use ...
3107 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3108 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3109 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3110 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3111 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3112 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3113 ... new macros.
3114 (_AC_CONFIG_UNIQUE): Update.
3115 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3116 Replaced by this ...
3117 (_AC_LIST_TAGS): ... new common macro.
3118 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3119 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3120 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3121 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3122 this didn't belong to the `config commands' section.
3123 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3124 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3125 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3126 to the `config commands' section either.
3127 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3128 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3130 ... and many changes to the comments nearby.
3132 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3133 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3134 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3135 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3136 (#define header templates): The comment at the top of the generated
3137 header now includes the name(s) of the source file(s).
3139 Several unrelated small changes:
3141 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3142 parameter to AC_DIAGNOSE.
3143 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3144 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3145 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3146 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3147 with AU::AC_OUTPUT.
3148 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3149 in AC_OUTPUT doesn't double-quote it either.
3150 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3151 parameters.
3153 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3155 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3156 versions of Portland Group compiler produce single- and double-quoted
3157 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3158 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3160 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3162 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3163 This is a corrected version of yesterday's patch.
3165 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3167 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3168 path, too; insert a "===" to emphasize the line.
3170 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3171 ac_cv_build_alias to ac_build_alias.
3172 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3174 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3175 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3176 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3177 (AC_ARG_VAR): ... here.
3178 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3179 target_alias.
3181 Keep a list of all precious variables and process them with one simple
3182 for loop, instead of expanding all commands, or, OTOH, complicated
3183 processing of output of "set".
3184 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3185 variable names in new macro...
3186 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.

3188 a loop to assign all ac_env_* and ac_cv_env_* variables.
3189 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3190 to INIT_PREPARE.
3191 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3192 its value to shell variable ac_precious_vars and call
3193 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.

3218 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3220 Fix my changes from 2005-07-01; reported by Noah Misch.

3231 versions of autoconf.
3233 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3235 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

3240 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3241 sed substitution command, so that we allow | in program prefixes
3242 and program suffixes. (& is a problem anyway; we're not fixing

3244 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3245 configure_input, top_builddir, srcdir, etc.
3246 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3247 PATH_SEPARATOR in AUTOTEST_PATH.
3249 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
3251 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the

3257 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

3283 for --help in that case.
3285 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3286 matches the order of execution. No code changed.

3308 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3309 (AC_SUBST): Call it.
3310 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3311 the directory specific variables; but don't call it for configure_input.
3313 2005-06-28 Derek Price <derek@ximbiot.com>
3315 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3316 addition.
3318 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3320 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3321 directory have inherent problems with special characters like spaces,
3322 due to limitations in Make syntax. Problem reported by Alexandre
3323 Duret-Lutz.
3324 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

3337 from Justace Clutter.
3338 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
3339 variable into diagnostic. Make the diagnostic an error, not a warning,
3340 because we really don't support spaces and suchlike in dir names.
3341 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3342 Don't worry about backslashes in srcdir; it can't happen now.

3369 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3370 b, t, r, w commands require single space, while : cannot have any.
3371 (Special Shell Variables): Fix sed code this in the example.
3372 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3373 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3375 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3376 expand to the empty list. Don't use two pairs of m4_changequote,
3377 it's not necessary.

3385 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3386 * doc/autoconf.texi:
3387 Don't mention Solaris versions so much, if a
3388 problem is common to all extant versions of Solaris. Say "SunOS
3389 4" instead of "SunOS" for SunOS 4.
3390 (awk): Mention more of the limitations of traditional Awk.
3391 (cat): Don't talk about cat -v.
3393 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

3398 to be compatible with glibc strverscmp.
3399 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
3401 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3402 on Mac OS X 10.4 reported by Peter O'Gorman in:

3409 * doc/autoconf.texi: "filesystem" -> "file system".
3410 "behaviour" -> "behavior".

3413 as per POSIX.
3414 * lib/m4sugar/m4sh.m4: Likewise.

3418 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
3419 (.x.1): Ignore the time stamp in the .TH line when deciding whether

3424 quotes and backslashes. Patch from Derek Price.

3429 AS_TR_SH.
3431 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
3433 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3434 -u, since it outputs chatter if the input files are the same.
3435 Problem reported by Ralf Menzel.
3437 2005-06-08 Derek Price <derek@ximbiot.com>
3439 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3440 renaming them since they are about to be redefined anyhow.
3442 2005-06-08 Derek Price <derek@ximbiot.com>
3444 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3445 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3446 Move m4_undefine to alphabetical order.
3448 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3450 * README: Recommend GNU M4 1.4.3 or later.
3451 * doc/autoconf.texi (Introduction): Likewise.
3452 Reword to avoid some formatting glitches.
3453 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3454 Clarify explanation of HP compiler bug.
3455 Redo example output tp match current CVS snapshot.
3456 Use @example.org in email addresses when the examples
3457 might get inadvertently cut-and-pasted into user code.
3458 Remove example of autom4te usage that doesn't seem to work now.
3459 Use modern AC_INIT (except when the example is meant to be
3460 shown with Autoconf 2.13).
3461 Update ksh info for Solaris 9 and later.
3462 KB -> kB.
3463 Modernize description of Automake versions a bit.
3464 Don't claim a future version of Autoconf is near.

3471 Reword to avoid some formatting glitches.
3472 * doc/installt.exi: Reword to avoid some formatting glitches.
3474 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3475 Tru64 ksh pattern matching bug. Reported against Libtool by
3476 Albert Chin <libtool@mlists.thewrittenword.com> and
3477 Nicolas Joly <njoly@pasteur.fr>.
3479 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3481 m4_cdr of one-member list was [[]] (one-member list containing an
3482 empty string) instead of [] (an empty list. Callers were skewed to
3483 match this misbehaviour. As a consequence of this:
3484 - m4_foreach([x], [], [foo]) expanded to `foo', while
3485 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3486 This bug has been fixed:
3488 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3489 expand to an empty string; print error msg if called without
3490 an argument list.
3491 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3492 misbehaviour; handle [] and [[]] correctly.

3500 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3502 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3503 swallow records with more than 99 fields.
3504 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3505 parse the long line.
3507 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3509 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3510 swallow literals longer than 399. Reported by Ralf Wildenhues.

3522 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3523 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3524 (testsuite): Make sure autotest.m4f is up-to-date before using it.

3528 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3529 expression of unbounded size when processing the --list
3530 option. This runs afoul of a limit of 399 bytes per regular
3531 expression on AIX. Problem reported by Ralf Wildenhues.

3540 Reword description of line replacement.
3542 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3544 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3545 now contain newlines, and substituted files must be referenced on
3546 a line alone; the sed scripts to substitute them are now very
3547 different.
3548 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3549 commands can be put in a sed script portably.
3550 * doc/autoconf.texi (Setting Output Variables): Document above

3563 classes in shell scripts. The test was too brittle.
3565 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3567 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3568 * doc/autoconf.texi (Limitations of Builtins): Document this
3569 limitation.
3571 2005-05-24 Stepan Kasal <kasal@ucw.cz>

3581 messages when ac_unique_file is not found.
3582 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3583 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo

3598 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3599 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3600 (ac_top_builddir): ... this ...
3601 (ac_top_build_prefix): ... to this; the old name is also kept, for
3602 backward compatibility.
3603 (ac_top_builddir_sub): New variable, without the trailing slash,
3604 always nonempty.
3605 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

3619 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3620 argument to m4_foreach. I guess it was necessary in the past,
3621 but I think it's a no-op now.
3623 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3625 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3626 ``cat <<_ACEOF'' commands to one.
3627 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3628 * lib/autoconf/status.m4: On various places, use expr instead of
3629 ``echo|sed.''
3630 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3631 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3632 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3633 a range.
3634 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3635 the wrong patterns between ``case'' and ``esac.'' The previous
3636 code had false positives.
3638 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3640 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3641 as on 2005-05-02.
3642 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3643 Mention LIBOBJDIR.

3686 check.
3687 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3688 enough arguments, similarly as in m4_bpatsubsts.
3690 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3692 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

3695 2005-05-11 Stepan Kasal <kasal@ucw.cz>
3697 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3698 for absolute directory names in one loop.
3699 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3700 abbreviations of --version and --debug.
3702 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3704 * doc/autoconf.texi (Autoconf Language): Be more precise about
3705 quoting rules. Problems noted by Stepan Kasal.
3706 Also, throughout this document, be more careful about white space.
3707 "blank", "white space", and "space" all have different meanings
3708 and we should be careful to say what we mean.
3710 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3712 Fix C++ related problems reported by Werner Lemberg.
3713 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3714 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3715 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3716 avoid problems with C++ and throw.
3717 * tests/compile.at: .cpp, not .cc.
3719 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3721 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3723 * doc/autoconf.texi (Generic Functions): Typos.
3725 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3727 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3728 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3729 set by latest automake.
3731 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3733 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3734 outputs 0 on GNU/Linux these days.
3736 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3738 * doc/autoconf.texi (Autoconf Language): Add more description
3739 about quoting heuristics.
3740 (Limitations of Builtins): Describe "set -" problems.
3742 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3744 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3745 not newline.
3747 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3748 by AC_DEFINE; it was a mistake.
3749 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3751 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3753 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3755 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3757 * doc/autoconf.texi (External Software): Quadrigraphs are not
3758 processed correctly in AS_HELP_STRING; avoid this in the examples.
3759 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3760 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3761 comment and reduce m4_default([foo], []) to [foo].
3762 (m4_strip): Update the explanation.
3764 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3766 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3767 Remove core.conftest.* too; it's generated by Tru64 5.1.
3768 Problem reported by Jennis Pruett.
3769 * lib/autoconf/functions.m4
3770 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3771 Don't bother to remove core files; AC_RUN_IFELSE should do that
3772 for you.
3774 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3776 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
3778 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

3783 2005-04-15 Stepan Kasal <kasal@ucw.cz>
3785 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
3786 the comment.
3788 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3790 * doc/autoconf.texi (External Software, Package Options): Add
3791 examples showing how to implement --with-* and --enable-* options.
3793 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3795 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3796 as well as configure.in. Problem reported by Gregorio Guidi.
3798 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3800 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3801 pattern for alloca snippet.
3803 2005-04-04 Stepan Kasal <kasal@ucw.cz>
3805 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

3811 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3813 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3814 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3816 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3818 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3819 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3820 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3821 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3822 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3824 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3826 * NEWS: The configure command now warns you if you attempt to use
3827 a directory whose name contains a special character like space,
3828 newline, or "\".
3829 * doc/autoconf.texi (Installation Directory Variables): Allow
3830 "," in file names. Do not use \@; it's not a portable regexp.
3831 * bin/Makefile.am (edit): Likewise.
3832 * lib/Makefile.am (edit): Likewise.
3833 * tests/Makefile.am (edit): Likewise.
3834 * tests/semantics.at: Likewise.
3835 * tests/torture.at: Likewise.
3836 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3837 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3838 * doc/autoconf.texi (File System Conventions): Warn about
3839 unportable file names.
3840 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3841 (AC_INIT): Use it.
3842 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3843 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3844 ac_pwd, and quote srcdir.
3845 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3847 * doc/autoconf.texi: Fix some systematic formatting problems.
3848 ".)" needs a following @: if not at the end of a sentence, and
3849 similarly for "!)". "etc." should be preceded by a comma.
3850 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3852 2005-03-22 Bruno Haible <bruno@clisp.org>
3854 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3855 argument is often called 'build-aux'.
3857 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3859 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3860 macro AC_TRY_LINK is obsolete.
3861 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3862 `AC_CONFIG_FILES'.
3864 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3866 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3867 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3868 from a Common Lisp's `cl'.
3869 (AC_PROG_CXX): Behave according to the documentation: don't
3870 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3871 make the variable CCC precious; use `cl.exe', not `cl'.
3873 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3874 Alexandre Duret-Lutz <adl@gnu.org>
3876 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3877 /dev/null, as "configure" shouldn't read stdin, and this insulates
3878 us from problems (e.g., when testing for "cl"). Also, do this
3879 redirection before invoking "hostname" or "uname", and keep the
3880 original input stream available via...
3881 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3882 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3883 bother with "</dev/null" since it's now done at the top of
3884 'configure'.
3885 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3886 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3887 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3888 * doc/autoconf.texi (File Descriptor Macros): New section.
3889 (Printing Messages): Mention it.
3890 * tests/base.at (Input/Output): New test.
3892 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3894 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3895 newline if neither \c nor -n work, as that would output two
3896 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3898 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3900 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3901 This causes that any required macros inside will get before the if.
3902 * doc/autoconf.texi (autom4te.cache): A typo.
3904 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3906 Undo previous change, except keep the change to
3907 lib/autoconf/programs.m4 that replaced grep with shell
3908 pattern-matching. This is because net-snmp configure reads stdin.
3909 Reported by Noah Misch.
3911 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3913 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3914 from /dev/null, as "configure" shouldn't read stdin, and this
3915 insulates us from problems (e.g., when testing for "cl").
3916 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3917 before invoking "hostname" or "uname".
3918 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3919 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3920 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3921 "</dev/null" since it's now done at the top of 'configure'.
3922 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3923 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3924 Also, replace grep with shell pattern-matching, to save a process.
3926 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3928 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3929 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3930 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3931 compiler.
3933 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3935 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3936 grep -q isn't portable. Improve grep -s explanation.
3937 Problem reported by Dan Manthey.
3939 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3941 * doc/autoconf.texi (Special Shell Variables): Clarify
3942 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3944 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3946 * doc/autoconf.texi: Use @acronym for DJGPP.
3947 Fix some @code's that should have been @env's, and vice versa.
3948 Sort environment variable names.
3949 Mention that shells no longer inherit IFS.
3950 Don't recommend PATH_SEPARATOR=';' so strongly.
3951 Mention that $RANDOM might expand to the empty string.
3952 "symlink" and "soft link" -> "symbolic link".
3953 Improve mktemp description (reported by Bruno Haible).
3955 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3957 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3958 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3959 Likewise.
3960 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3961 Likewise.
3963 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3965 * NEWS: Mention AT_COPYRIGHT.
3967 * tests/local.at (AT_CMP): Use diff directly on input files rather
3968 than copying them.
3970 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3971 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3973 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3974 and Paul Eggert <eggert@cs.ucla.edu>
3976 * tests/autotest.at (Empty test suite): New test.
3977 * tests/torture.at (Substitute and define special characters)
3978 (Substitute a 2000-byte string, Define to a 2000-byte string)
3979 (Substitute a newline, Define a newline): New tests.
3981 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3983 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3984 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3985 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3986 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3987 (Standard regular expressions): New test.
3988 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3989 excess test name quoting.
3990 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3991 CPPFLAGS to `configure' instead of setting it in `configure'.
3993 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3994 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3995 on some platforms.
3997 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3998 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
4000 * tests/local.at (AT_CMP): New macro.
4001 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
4002 (AC_SAVE_STATE): Move environment grep...
4003 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
4004 (AT_CONFIG_CMP): New macro.
4005 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
4006 * tests/c.at (Extensions): Do not exit early.
4007 * tests/atlocal.in: Inherit $GREP.
4009 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
4010 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
4012 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
4013 (AC_COPYRIGHT): Factor header comment portion out and move into...
4014 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
4015 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
4016 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
4017 --version output.
4018 * tests/local.at: Add Autoconf test suite copyright notice.
4019 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
4021 2005-02-04 Bruno Haible <bruno@clisp.org>
4022 and Paul Eggert <eggert@cs.ucla.edu>
4024 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
4026 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4028 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4029 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4031 Try not to generated lines of unlimited length, as POSIX places a
4032 2047-byte limit on line length of portable text files.
4033 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4034 Use newline as a separator, not space.
4035 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4036 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4037 space.
4039 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4041 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4042 as_func_*. Add test to check whether positional parameters
4043 are restored after function return.
4045 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4047 * doc/autoconf.texi (Special Shell Variables): Mention _,
4048 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4049 if they contain a lower-case letter. The DUALCASE problem was
4050 reported by Ralf Wildenhues.
4052 * bin/autoconf.as: Don't exit with status 0 after write failure
4053 with --help or --version.
4054 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
4055 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
4057 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4059 * doc/autoconf.texi (Limitations of Usual Tools):
4060 Unicos 9 sed limitations.

4069 Modified from a suggestion by Stepan Kasal.
4071 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
4072 with a cross reference. Derived from a suggestion by Bruce Korb.

4092 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4093 Update the long comment explaining it.
4095 m4_require no longer writes an ``is required by'' line to the
4096 execution stack. It contains only one bit of non-redundant
4097 information: that the macro was required, not called. And even
4098 this bit is useless in most situations: have you ever met a macro
4099 which both calls and requires the same macro?
4101 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4102 (_m4_defun_pro_outer): ... only via this macro, for the outermost

4110 * tests/m4sugar.at (m4_require): Expect output without the
4111 ``is required by'' messages.
4113 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4115 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4116 rather than x for expr.
4118 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4119 this is safe.
4120 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

4136 config.h.in is always recreated when --force.

4147 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4149 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4150 Warn about newline stripping in `` and $(). Update Solaris
4151 version to 9.

4155 stripping.
4157 2005-01-19 Stepan Kasal <kasal@ucw.cz>

4177 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
4179 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4181 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

4205 otherwise.
4206 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4207 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4208 stored in _m4_divert_diversion or _m4_divert_dump.
4209 (m4_divert_pop): When the parameter is given, compare the symbolic
4210 name with the last diversion pushed on the stack. Previously, the
4211 current diversion was compared with the numeric value of the
4212 diversion given as the parameter.
4213 (m4_require): If the macro hasn't been expanded yet, call ...
4214 (_m4_require_call): this new macro.

4247 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

4249 not essential. Reported by Magnus Therning.
4250 * tests/torture.at (autoreconf.): New banner.
4251 (autoreconf and non-AC configure): Rename to `Non-Autoconf

4300 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
4301 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

4428 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

4516 value of the #define--default to 1, iff the macro was called
4517 with exactly one parameter.
4519 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4521 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4522 "char c = '\200';" rather than "char c = 0x80;" as the
4523 latter doesn't conform to the strict C standard due to
4524 overflow on signed char hosts.
4526 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4527 to -qlanglvl=ansi. We don't want to disable extensions.
4529 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
4531 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
4532 (Using Autotest, testsuite Scripts, Writing testsuite.at):
4533 Reword slightly to avoid some English-language problems noted

4547 Automake (not without Autoconf).
4548 (Introduction): Mention lists.gnu.org.
4549 * BUGS: Don't mention bugs.gnu.org.
4550 Remove mention of ancient libtool compatibility problem.
4551 * NEWS: Mention that bugs.gnu.org is kaput.

4579 * doc/autoconf.texi (Autoconf Language): Explain that
4580 ``descriptions'' may not be double quotes.
4581 (Quotation Rule Of Thumb): Likewise.
4582 (Pretty Help Strings): Likewise; remove the wrong comment;
4583 simplify the examples and improve their quoting.
4585 2004-11-13 Stepan Kasal <kasal@ucw.cz>
4587 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
4588 the $1_found variable, don't test whether the file is executable;
4589 Both things are checked ...
4590 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
4591 the former ``test -f''.
4592 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
4594 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

4597 use cp -R instead.
4599 2004-11-10 Derek R. Price <derek@ximbiot.com>
4601 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
4602 limitations. Reorder paragraphs for clarity.
4604 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
4606 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
4607 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
4608 variants", "Unix", and some related minor wording fixups.
4610 (Shellology, Special Shell Variables): Document that the Zsh
4611 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
4612 to Alexandre Duret-Lutz for this info.

4623 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
4625 * doc/autoconf.texi (auindex): New macro.
4626 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
4627 Problem reported by Stepan Kasal.
4629 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
4631 Fix problems reported by Andreas Buening in:
4632 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
4633 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
4634 in test makefile.
4635 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
4636 readable; it's not true in OS/2-emx.
4638 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4640 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4641 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4642 (trivial change). Problem and patch reported by Andrew Church in:
4643 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4645 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
4647 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
4648 three args in examples. Problem reported by Frederik Fouvry in:

4650 Also, fix some minor spacing and punctuation bugs.
4652 2004-09-02 Akim Demaille <akim@epita.fr>
4654 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
4655 "case" to restore ordering.
4656 Reported by Stepan Kasal.

4666 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
4668 Version 2.59b.
4670 * README: Add advice about m4 1.4.2.
4672 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4673 texinfo.tex for now (done by hand now).
4674 * Makefile.maint (wget_files, cvs_files):
4675 Remove ansi2knr.c; nobody uses it.
4676 (ansi2knr.c-url_prefix): Remove.
4677 (cvs-update): Fix test for failure. I don't know why it ever
4678 worked...
4680 * doc/autoconf.texi: Update URLs, some of which went stale.
4681 Use @uref rather than @href.
4683 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4684 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4686 * config/config.guess, config/config.sub, config/elisp-comp,
4687 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4688 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4690 * NEWS, TODO, configure.ac, bin/autoscan.in,
4691 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4692 doc/install.texi, lib/Autom4te/Configure_ac.pm,
4693 lib/Autom4te/FileUtils.pm, lib/autoconf/general.m4,
4694 lib/autoconf/programs.m4, lib/autoconf/status.m4,

4696 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4697 tests/tools.at, tests/torture.at:
4698 Use "file name" rather than "filename" or "path",
4699 to be consistent with the terminology of the GNU coding standards.
4701 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4703 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4704 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4705 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4706 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4708 More fixes to support spaces in the name of the build directory.
4709 This isn't a complete fix but it's an improvement.
4711 * bin/autoconf.as (autom4te_options): New var.
4712 Use it instead of appending to AUTOM4TE, so that we can allow
4713 spaces in the build directory's absolute name.
4714 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4715 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
4716 AT_CHECK_NOESCAPE): Likewise.
4717 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
4718 main program): Likewise.
4720 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
4722 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
4723 From Ralf Corsepius in:
4724 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
4726 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4728 * doc/autoconf.texi (Function Portability): Document isinf and
4729 and isnan. From a suggestion by Kevin Ryde.
4731 * lib/Autom4te/General.pm (END): Return correct exit status even
4732 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4734 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4736 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4737 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4738 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4740 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4742 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4743 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4744 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4745 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4746 * lib/autom4te.in (Automake-preselections): Preselect
4747 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4749 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4751 * lib/autom4te.in (Automake-preselections): Preselect
4752 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4753 trace them.
4755 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4757 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4758 Tru64.
4759 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4760 Document problem with "`""`" in pdksh POSIX mode.
4762 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4764 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4765 with pdksh, too. Problem reported by Patrick Welche via
4766 Gary V. Vaughan.
4767 * doc/autoconf.texi (Shellology): Note that set -o posix is
4768 useful for pkdsh, too.
4770 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4772 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4773 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4774 Don't fail if ENV or BASH_ENV is readonly.
4775 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4776 etc. are read only. Problem reported by Ludovic Courtes.
4778 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4780 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4781 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4782 (trivial change)
4784 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4786 * doc/autoconf.texi (File System Conventions): Warn about
4787 names like "aux". Problem reported by Eric Blake.
4789 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4790 by zero instead of array size, so that we can use any arithmetic
4791 constant expression (instead of requiring an integer constant
4792 expression). This allows us to test expressions like DBL_MAX <
4793 LDBL_MAX, which didn't conform to the C standard using the old
4794 method.
4795 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4796 now that we can do floating-point tests at compile time.
4798 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4800 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4801 and LDBL_EPSILON, as the resulting expression isn't an
4802 integer constant expression and violates the C standard.
4803 Problem reported by Nelson H. F. Beebe. Also, check
4804 for "L" suffix, and check that long double doesn't have
4805 worse range or precision than double, that mixed-mode
4806 arithmetic doesn't generate a diagnostic, that double
4807 constants fit in long double.
4809 2004-06-03 Kevin Ryde <user42@zip.com.au>
4811 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4812 malloc(0) and realloc(NULL,size).
4814 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4815 Bob Proulx.
4817 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4819 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4820 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4821 by Jim Meyering.
4823 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4825 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4826 can be rewritten using if-then-else. Suggested by Bruno Haible.
4828 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4830 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4831 Problem reported by Stepan Kasal.
4833 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4835 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4836 change). Patch reported by Ralf Wildenhues in
4837 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4839 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4840 function F exists if the compiler and linker let you compile an
4841 expression like (F != 0). Recent versions of GCC optimize away
4842 the reference to F in that case, since every function address must
4843 be nonzero, so the link succeeds even if F does not exist.
4844 Problem reported by Manu in
4845 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4847 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4848 "Unix". Many uses changed.
4849 (Limitations of Builtins): Explain better why the ! command isn't
4850 portable.
4852 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4854 * lib/autom4te.in (Automake-preselections): Preselect
4855 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4857 2004-05-19 Kevin Ryde <user42@zip.com.au>
4859 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4860 referencing AC_FUNC_STRERROR_R.
4862 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4863 note pessimistic assumption when cross compiling.
4865 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4867 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4868 (until 2004) invoked subcommands with sh -e, contra POSIX.
4869 Reported by Kevin Ryde.
4871 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4873 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4874 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4875 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4876 `test -f " /usr/bin/grep"', which _always_ failed.
4877 (AC_PROG_SED): Ditto bogus PATH fix.
4878 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4879 requires that grep correctly supports _multiple_ `-e' options, rather
4880 than stating only that grep should accept `-e'.
4882 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4884 Port to C99, which requires that 'exit' be declared.
4886 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4887 to ensure that stdlib.h is included.
4888 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4889 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4890 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4891 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4892 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4893 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4894 when using 'exit' in a test; C99 requires that 'exit' be declared.
4896 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4898 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4899 now prefers 'grep' implementations that accept -e.
4900 (Limitations of Usual Tools): Describe problems of traditional
4901 egrep and fgrep with long input lines, and of traditional grep
4902 with -e.
4903 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4904 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4905 All callers changed. Append /usr/xpg4/bin to the PATH, for
4906 Solaris.
4907 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4908 the user with complaints about multiple -e options.
4909 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4910 Define it with AC_PROG_GREP.
4911 * configure.ac (AC_PROG_GREP): Add.
4912 * lib/freeze.mk (GREP): New macro.
4914 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4916 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4917 a possible candidate only after all others fail, rather than
4918 consulting it first. This improves backward compatibility by
4919 better reflecting the way shell selection occurred in previous
4920 versions of Autoconf, and should help to avoid triggering latent
4921 problems in other packages, such as the one in Automake where zsh
4922 is not handled robustly:
4923 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4924 Although it is not Autoconf's responsibility to work around
4925 problems in Automake, it nevertheless makes sense to avoid
4926 introducing unnecessary incompatibilites.
4928 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4929 Gary V. Vaughan <gary@gnu.org>
4931 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4932 how deeply nested we are when a suitable tool is found, set the
4933 ac_path_TOOL_found flag.
4934 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4935 nested we are in this macro. Break out of all 3 nested loops if
4936 ac_path_TOOL_found is set.
4938 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4940 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4941 of the _AS_PATH_WALK loop too if GNU flavor is found.
4943 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4945 * doc/autoconf.texi (Limitations of Make): Update documentation
4946 for `$<'. New entry `Long lines', based on a report from Simon
4947 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4948 paragraph about DJGPP, based on a mail from Richard Dawe.
4950 2004-04-20 Paul Eggert <eggert@twinsun.com>
4952 * tests/c.at (C keywords): Don't assume that GCC supports
4953 "restrict" and "inline", as sufficiently-old GCC versions do not
4954 (also, GCC configured to be in pedantic C89 mode does not).
4955 Problem reported by Sumit Pandya in:
4956 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4958 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4959 consider -g to work if it generates warnings when plain compiles
4960 don't. Problem reported by Braden McDaniel in:
4961 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4963 * doc/autoconf.texi (Slashes): New section, to document a problem
4964 reported by Jim Meyering in:
4965 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4967 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4968 linker output files before linking, to work around IRIX 6 linker bug.

4970 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4972 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4974 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4975 best tool so far counter rely on the tool path variable name to
4976 avoid checks for one tool being affected by the results of running
4977 the length check on a previous tool.
4979 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4980 match expression argument, as different greps have different
4981 regular expression flavours.
4982 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4983 literals.
4984 (AC_PROG_EGREP): Pass 'EGREP$'.
4985 (AC_PROG_GREP): Pass 'GREP$'.
4987 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4989 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4990 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4992 2004-03-29 Paul Eggert <eggert@twinsun.com>
4994 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4995 Types, Specific Compiler Characteristics, System Services,
4996 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4997 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4998 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4999 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5000 Likewise.
5001 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5002 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5003 AC_TYPE_OFF_T): Likewise.
5004 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5005 Likewise.
5007 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5008 pacify libtool 1.5.2. Fix quoting problems in sed command.
5010 2004-03-28 Paul Eggert <eggert@twinsun.com>
5012 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5013 now defines HAVE_DECL_TZNAME if it is declared, when
5014 HAVE_STRUCT_TM_TM_ZONE is not defined.
5015 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5016 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5017 for HAVE_TZNAME.
5019 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5021 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5022 superfluous backslashing of quotes (") in sed expressions;
5023 thanks to Paul Eggert.
5025 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5027 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5028 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5029 H. F. Beebe for the bug report.
5031 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5033 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5034 quoted -cmdline argument in Portland Group compiler (bug
5035 reported by Jeffrey J. Barteet).
5037 2004-03-25 Kevin Ryde <user42@zip.com.au>
5039 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5040 (Run Time): ... here, where it's now mentioned.
5042 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
5044 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5045 inherits from language Autoconf-without-aclocal-m4.
5046 (Customizing autom4te): Adjust example; the cache must now be
5047 disabled for language Autoconf-without-aclocal-m4.
5049 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
5050 Nathanael Nerode <neroden@twcny.rr.com>

5060 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
5061 AC_CHECK_TOOLS.
5062 (Specifying Names): Document the reason for these future
5063 behavioral changes.
5064 * tests/mktests.sh: Do not generate tests for the
5065 new macros.
5066 * NEWS: Document these changes.
5068 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5069 they make TeX hang up.
5071 2004-03-15 Paul Eggert <eggert@bogus.example.com>
5073 * NEWS: New macro AC_CHECK_ALIGNOF.
5074 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5075 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5076 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5077 vowel.
5078 (AC_CHECK_ALIGNOF): New macro.
5079 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5080 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5081 those for sizeof.
5083 2004-03-03 Paul Eggert <eggert@twinsun.com>
5085 * bin/Makefile.am (edit): Don't use $< in a context where
5086 POSIX doesn't require support for it. Use $@.in instead.
5087 Problem reported by Anthony N. Frasso in
5088 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5089 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5091 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5093 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5094 from the next generation of Libtool.
5095 * lib/autom4te.in (Autoreconf-preselections): Ditto.
5097 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5099 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
5100 is not always thread-safe. Report from Nathanael Nerode.
5102 2004-02-18 Paul Eggert <eggert@twinsun.com>
5104 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5105 problem on QNX reported by Stephen Rasku in
5106 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5108 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5109 $(m4sh_m4f_dependencies); this removes a FIXME.
5110 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5111 (MAINTAINERCLEANFILES): Split into pieces,
5112 one per related section. Add $(srcdir)/wrapper.in.
5114 2004-02-09 Paul Eggert <eggert@twinsun.com>
5116 * doc/autoconf.texi (Setting Output Variables): Emphasize that
5117 AC_SUBST provides no portable way to escape literal newlines.
5119 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5120 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5121 Darwin uses -lcrt2.o and there's little point to cataloging all
5122 the system variants. Partial fix reported by Andreas Waechter in:
5123 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5124 for bug reported by Nelson H. F. Beebe in:

5127 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
5129 * doc/autoconf.texi (AU_DEFUN): Fix English,
5130 suggested by Paul Eggert.
5131 * lib/autoconf/autoupdate.m4: Correct reference to
5132 acobsolete.m4, suggested by Alexandre Duret-Lutz.
5134 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
5136 * bin/autoupdate.in: Define __file__ so that warnings
5137 refer to the correct file.
5138 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5139 the behavior of the third argument.
5140 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5141 correctly the behavior of the third argument. Document
5142 what the three macros that AU_DEFUN defines do. Fix
5143 warning message when the third argument includes $0
5144 (reported by Alexandre Duret-Lutz).
5146 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5147 Eric Sunshine <sunshine@sunshineco.com>
5148 Paul Eggert <eggert@twinsun.com>
5150 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5151 (AS_INIT): Output shell initialization there. Removed optional
5152 parameter. Expand _AS_SHELL_FN_SPY.
5153 (AS_INIT_WITH_SHELL_FN): Removed.
5154 (_AS_SHELL_FN_SPY): New macro.
5155 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5156 macros.
5157 (AS_SHELL_SANITIZE): Remove loop to find better shell
5158 and documentation for the parameter.
5159 (_AS_DETECT_BETTER_SHELL): Move it here.
5160 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
5161 (_AS_RUN): Move it here, support testing with eval.
5162 (AS_REQUIRE_SHELL_FN): Require shell functions when
5163 it is used.
5164 (_AS_LINENO_WORKS): Put around braces, we do not
5165 trigger the bash bug anymore.
5166 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5167 use AS_INIT_WITH_SHELL_FN.
5168 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5170 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5172 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
5173 * doc/autoconf.texi: Don't say that the third parameter
5174 is broken.
5175 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
5176 (AU_DEFUN): Honor the third parameter, create autoupdate
5177 macros with AU_DEFINE.
5178 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
5179 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
5180 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
5181 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
5182 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

5187 * lib/autoconf/status.m4: Remove FIXME.
5188 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
5189 that the macro is not present anymore in the updated
5190 configure.ac.
5191 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
5192 of autoupdate.
5194 2004-01-28 Paul Eggert <eggert@twinsun.com>
5196 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
5197 copyright years.
5198 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5199 2003 (except 1997) to the list of copyright years. This undoes
5200 the 2003-05-22 change, which removed the older years from the list.
5201 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5203 2004-01-27 Gary V. Vaughan <gary@gnu.org>
5204 Albert Chin-A-Young <china@thewrittenword.com>
5206 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
5207 grep or ggrep program in PATH that accepts as long lines as
5208 possible.
5209 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
5210 AC_PROG_GREP.
5211 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5212 egrep and fgrep respectively if $GREP -E/-F don't work.
5213 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5214 _AC_PROG_GREP, and AC_PROG_SED.
5215 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5216 longest input length accepted by a command.
5217 (AC_PROG_SED): Use it.
5218 * doc/autoconf.texi (Particular Programs): Document the changes.
5219 * NEWS: Updated.
5221 2004-01-27 Paul Eggert <eggert@twinsun.com>
5223 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
5224 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
5225 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
5226 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
5228 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
5229 bin/autoconf.in, config/Makefile.in, config/config.guess,
5230 config/config.sub, config/install-sh, config/mdate-sh,

5241 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
5242 tests/actypes.at: Regenerate and/or sync with original
5243 sources.
5245 2004-01-26 Paul Eggert <eggert@twinsun.com>
5247 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5248 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5249 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5250 not <inttypes.h>. Problem reported by Tim Mooney in
5251 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5252 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5253 Likewise.
5255 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5256 otherwise "make check" fails because it forbids cmp (I guess
5257 because cmp treats files as binary on DOS-like systems).
5259 * tests/mktests.sh: Update copyright date to 2004, since some tests
5260 have changed in 2004.
5262 2004-01-23 Gary V. Vaughan <gary@gnu.org>
5264 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
5265 non-truncating sed or gsed program in PATH.
5266 * tests/acprograms.at: Add it.
5267 * doc/autoconf.texi (Particular Programs): Document it.
5268 * NEWS: Updated.
5270 2004-01-15 Paul Eggert <eggert@twinsun.com>
5272 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5273 -std1 disables some useful extensions on Tru64. Problem reported
5274 by N. Lichtmaier in
5275 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5277 2004-01-14 Paul Eggert <eggert@twinsun.com>
5279 * doc/autoconf.texi (Programming in M4sh): Document that
5280 AS_MKDIR_P succeeds if the destination is a symbolic link
5281 to an existing directory.
5282 (Limitations of Usual Tools): Note that mkdir -p might not
5283 succeed on symlinks to directories.
5285 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5287 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
5288 * bin/autoheader.in: Grammar fix in message.
5289 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
5290 Test for dir before calling mkdir -p. (trivial changes)
5292 2004-01-13 Eric Blake <ebb9@byu.net>
5294 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5295 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5297 2004-01-10 Jim Meyering <jim@meyering.net>
5299 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
5301 2004-01-09 Paul Eggert <eggert@twinsun.com>
5303 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5304 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5305 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5306 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5307 AC_COMPILE_IFELSE, since we now assume our caller invokes
5308 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5309 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5310 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5311 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5313 2004-01-07 Paul Eggert <eggert@twinsun.com>
5315 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5316 `"'...'"`, as it's confusing (and I suspect it may not work on
5317 some platforms). The code was incorrect anyway, as it assumed
5318 that \$ evaluated to itself in that context. Reported by
5319 Alexandre Duret-Lutz.
5321 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
5323 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
5324 and _LT_AC_TAGCONFIG.
5326 2004-01-06 Paul Eggert <eggert@twinsun.com>
5328 * doc/autoconf.texi (One Macro Call): Fix an incorrect
5329 example, and add more examples. Reported by Eric Sunshine.
5331 2004-01-05 Paul Eggert <eggert@twinsun.com>
5333 * doc/autoconf.texi (Limitations of Usual Tools):
5334 Remove warning against "rm -fr" introduced yesterday; it
5335 was a false alarm.
5337 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
5338 autoscan, autoupdate, ifnames): Don't use chmod -w.
5339 * lib/Makefile.am (autom4te.cfg): Likewise.
5340 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
5341 "chmod -w".
5343 2004-01-04 Paul Eggert <eggert@twinsun.com>
5344 Paolo Bonzini <bonzini@gnu.org>
5346 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
5347 by doing lineno substitution only on lines containing "$LINENO".
5349 2004-01-04 Paul Eggert <eggert@twinsun.com>
5351 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
5352 Use "rm -f" to remove conftest.sed, not plain "rm".
5353 Bug reported by David Relson in
5354 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
5356 * Makefile.am (autom4te-update):
5357 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
5358 * Makefile.maint (my-distcheck, do-po-update): Likewise.
5359 * doc/autoconf.texi (Guidelines): Likewise.
5360 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

5364 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
5365 * tests/Makefile.am (clean-local): Likewise.
5366 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
5367 srcdir): Likewise.
5368 * doc/autoconf.texi (Limitations of Usual Tools):
5369 Warn against "rm -fr".
5371 2004-01-03 Paul Eggert <eggert@twinsun.com>
5373 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5374 -c -o might not work. From a suggestion by Kevin Ryde.
5375 (C Compiler, Generating Sources, Limitations
5376 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5377 Don't put '-o' after non-options, as POSIX doesn't allow this.
5378 Mention that cc's name might be gcc or c89 or whatever.
5380 2004-01-04 Kevin Ryde <user42@zip.com.au>
5382 * doc/autoconf.texi: Add various further index entries.
5384 2003-12-29 Paul Eggert <eggert@twinsun.com>
5386 * bin/autoreconf.in (autoreconf_current_directory):
5387 Fix typo: mkdir without umask arg.
5389 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
5391 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
5392 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
5393 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
5394 explanation clearer.
5396 2003-12-24 Andreas Schwab <schwab@suse.de>
5398 * doc/autoconf.texi (Default Includes): Fix misspelling of
5399 AC_INCLUDES_DEFAULT.
5401 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
5403 * configure.ac: Test if sh -n works.
5404 * configure: Regenerate.
5405 * tests/atlocal.in: Store the result here.
5406 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
5407 tools.at, looking in atlocal's ac_cv_sh_n_works instead

5445 * config/announce-gen (&print_locations, &print_signatures)
5446 (&sizes): New.
5447 Use them.
5448 No longer rely on Gnus to inline the list of signatures: compute
5449 them on the fly.
5451 2003-11-24 Akim Demaille <akim@epita.fr>
5453 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
5454 override some files.
5455 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
5456 From Debian Autoconf 2.58.
5458 2003-11-24 Akim Demaille <akim@epita.fr>

5522 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

5657 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5658 cross test.
5660 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5662 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5663 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

5675 Problems reported by Eric Sunshine.
5677 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5679 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5680 -mGLOB_options_string stuff for Intel ifc, which can cause

5704 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5705 cache variable instead of $G77 to decide whether to include -O2,
5706 since $G77 is specific to Fortran 77.

5710 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

5715 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5716 arguments so that it can be used with syntax identical to
5717 AC_PROG_F77, and so that we can more easily decide to
5718 remove/deprecate the DIALECT optional argument in the future if it
5719 proves troublesome.
5720 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5721 non-freeform-supporting compilers. Document freeform flags.
5723 2003-10-03 Akim Demaille <akim@epita.fr>
5725 * configure.ac: Look for emacs, not macs.
5726 Reported by Eric Sunshine.
5728 2003-10-03 Akim Demaille <akim@epita.fr>
5730 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5731 * bin/autoreconf.in (autoreconf_current_directory): Create the

5733 Suggested by Alexandre Duret-Lutz.
5735 2003-10-03 Akim Demaille <akim@epita.fr>
5737 * configure.ac: Quotation and formatting changes.

5759 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
5760 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

5767 (@news_file): this.
5769 2003-09-30 Nicolas Joly <njoly@pasteur.fr>

5772 have been created when invoking the compiler.

5786 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5787 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5788 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5790 2003-09-26 Akim Demaille <akim@epita.fr>
5792 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5793 directory for AC_CONFIG_COMMANDS' first argument exists.
5794 This makes valid the invocation of _AC_SRCPATH that follows.
5795 Reported by Eric Sunshine.
5796 * doc/autoconf.texi (Configuration Commands): Adjust.
5798 2003-09-26 Akim Demaille <akim@epita.fr>
5800 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5801 Reported by Ralf Corsepius.
5803 2003-09-26 Akim Demaille <akim@epita.fr>
5805 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5806 arguments.

5817 2003-09-26 Akim Demaille <akim@epita.fr>
5819 The test suite are sometimes assigning timings incorrectly.
5820 Reported by Henk Krus.
5821 Diagnosed by Nicolas Joly.
5823 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5824 AT_help_all.
5825 Instead of making AT_help a sequence of assignments to grow
5826 $at_help_all, just make AT_help_all be the growing contents of
5827 $at_help_all, and make a single assignment in...
5828 (AT_INIT): here.
5829 (at_times_skip): Flip the meaning and rename as...
5830 (at_times_p): this.
5831 (AT_INIT): When summarizing the test that ran, remove
5832 $at_times_file after use, and check it is present before trying to
5833 use it.

5841 (ifnames): chmod -w.
5842 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5843 executables, not bin/ executables! Otherwise all the magic needed
5844 to find non installed files is turned off. This caused a failure
5845 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5846 as found in its environment (sent by tests/autoreconf): pointing
5847 to bin/autom4te that could not find its files.
5848 * tests/mktests.sh: Force the replacement of generated files, for
5849 the sake of "mv" program that are interactive when overwriting a
5850 -w file.
5851 * config/install-sh: Upgrade from CVS Automake.
5853 2003-09-23 Paul Eggert <eggert@twinsun.com>

5861 Trivial change to support GCC's configuration procedure.
5862 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5863 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5864 about inconsistency if the preprocessor is set to give errors for
5865 any warning.
5866 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5868 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

5884 2003-09-12 Akim Demaille <akim@epita.fr>
5886 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5887 not asm/types.h.
5889 2003-09-11 Akim Demaille <akim@epita.fr>
5891 * doc/autoconf.texi (Header Portability): linux/random.h.
5892 From Peter Hendrickson.
5894 2003-09-10 Akim Demaille <akim@epita.fr>
5896 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5897 willing to edit the output files.
5899 2003-09-10 Akim Demaille <akim@epita.fr>
5901 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5902 and AC_FC_FREEFORM.

5924 2003-09-05 Paul Eggert <eggert@twinsun.com>
5926 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5927 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5929 2003-09-04 Akim Demaille <akim@epita.fr>
5931 * tests/mktests.sh (ac_exclude_list): Fix the filtering of

5944 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5946 Add support for newer Fortran dialects. The F77 interface is
5947 unchanged, and continues to support Fortran 77. New FC macros
5948 correspond to all the old F77 macros, with output variables FC,
5949 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5950 available dialect, but older dialects can be specified. There are
5951 new macros AC_FC_SRCEXT to set the source extension, and
5952 AC_FC_FREEFORM to accept free-form source files.
5954 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

5982 Document problems with timestamp resolution that 'make', 'cp -p', and
5983 'touch -r' have.
5985 2003-08-27 Akim Demaille <akim@epita.fr>
5987 * tests/m4sugar.at (cross_warning): Make sure to enable the
5988 output, so that we can track spurious m4sugar output.
5989 * tests/local.at: Require 2.57.
5990 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5991 are defaulted by AT_CHECK anyway.
5992 Use AT_CHECK_AUTOM4TE.
5993 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5994 missing dnl.
5996 2003-08-27 Akim Demaille <akim@epita.fr>
5998 * bin/autoheader.in: Issue the "Using auxiliary..." message only

6043 * configure.ac: Require Automake 1.7.6.
6045 2003-08-22 Akim Demaille <akim@epita.fr>
6047 Output stack traces in warnings.
6049 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.

6051 (m4_warn): Pass the call stack to _m4_warn.
6052 * bin/autom4te.in: Adjust to output the call stack.

6062 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6063 (&verbose): Remove.
6064 (&getopt): Adjust the note and verb channels, depending upon
6065 --verbose.

6067 * bin/autoupdate.in: Adjust.
6068 Use &verb, not &verbose.
6070 2003-08-21 Akim Demaille <akim@epita.fr>

6078 2003-08-21 Akim Demaille <akim@epita.fr>
6080 First stab at preserving warnings between calls to autom4te,
6081 including when the cache is used.
6083 There are still several issues: (i) there are too many runs of m4
6084 (one for include, one for warnings, and some more), (ii) warnings
6085 spreading on several lines are not handled gracefully, (iii) the
6086 code meant to have the call stack display for errors does not work
6087 (its handling should move from m4 to autom4te).
6089 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6090 Use them.
6091 (@preselect): Add m4_warn.
6092 ($exit_status): Remove, use $exit_code.
6093 ($help): Use Autom4te::ChannelDefs::usage.
6094 (&handle_m4): No longer define the m4_warnings.
6095 At each run, extract and report the warnings.
6096 Always cache the result, including if the exit status is on
6097 failure, since if nothing changes, we should result in the same
6098 failure, hence we can use the cache.
6099 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6100 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6101 Remove.
6102 (m4_warn): Redefine as a do-nothing: it is its invocation that
6103 matters, as warnings are now reported via traces.
6104 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6105 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6106 the latter reveals calls to the former.
6108 Adjust the tests.
6110 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6112 2003-08-21 Akim Demaille <akim@epita.fr>
6114 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6115 Use them.
6117 2003-08-21 Akim Demaille <akim@epita.fr>
6119 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6120 forward order.
6121 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6122 (&parse_warnings): Accept a list of warning requests.
6123 (&usage): Return a string, not a side effect.
6124 (cross): New warning category.
6126 2003-08-21 Akim Demaille <akim@epita.fr>
6128 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6129 (&require_configure_ac): Accept an optional directory argument.
6130 ($configure_ac): Remove.
6131 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6132 (&catfile): Remove.
6133 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6134 * bin/autoscan.in: Adjust.
6136 2003-08-20 Akim Demaille <akim@epita.fr>
6138 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6139 Reported by Alexandre Duret-Lutz.
6141 2003-08-20 Akim Demaille <akim@epita.fr>
6143 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6144 * bin/autom4te: Adjust.
6145 In particular, be Autoconf tools are really silent when properly
6146 working, bind the verbosity of the 'note' channel to $verbose.
6147 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6148 (&xsystem, &contents): Remove, since they are exported by...
6149 * lib/Autom4te/FileUtils.pm: this.
6150 More perldoc.
6151 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6152 * lib/Autom4te/FileUtils.pm: here.
6154 2003-08-20 Akim Demaille <akim@epita.fr>
6156 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
6157 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

6209 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
6210 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6211 shorter column three. Add DESCRIPTION to log file content.
6213 2003-08-13 Derek Price <derek@ximbiot.com>
6215 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6216 output.
6218 2003-08-12 Derek Price <derek@ximbiot.com>

6224 2003-08-07 Derek Price <derek@ximbiot.com>
6226 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
6227 (AT_CHECK_NOESCAPE): ...to this new macro.
6229 2003-07-31 Paul Eggert <eggert@twinsun.com>
6231 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
6232 in Bash 2.01. Problem reported by Brian Gough in
6233 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
6235 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>

6243 inside '#ifndef __cplusplus'. Problem reported by
6244 Bob Friesenhahn.
6246 2003-07-06 Bill Clarke <llib@computer.org>
6248 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
6249 'long', not 'int', for benefit of Sun's recent C++ compilers
6250 (trivial change). See:
6251 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
6252 (This really should be 'intptr_t', not 'long', but that would
6253 take more work.)
6255 2003-06-25 Akim Demaille <akim@epita.fr>
6257 * lib/Makefile.am (autom4te.cfg): Make it read only.
6258 Depend on Makefile since it contains substitutions.

6271 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6272 not all of them. This fixes 1. the fact that when testing
6273 Autoconf there are many many config.log, 2. the incorrect use of
6274 top_srcdir to find config.log.
6275 Don't mix the detailed output of failed test with the summary of
6276 failures. Rather, append detailed log afterwards.
6278 2003-06-23 Akim Demaille <akim@epita.fr>
6280 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

6363 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6365 * lib/Autom4te/General.pm (END): Rewrite exit code processing.

6382 exit 63, so that we (or Automake's "missing") can tell the
6383 difference with a plain failure.
6384 * doc/autoconf.texi (Notices): Adjust.
6386 2003-05-23 Akim Demaille <akim@epita.fr>
6388 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6389 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6390 White spaces cleanup.
6392 2003-05-22 Jim Meyering <jim@meyering.net>
6393 Paul Eggert <eggert@twinsun.com>
6395 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6396 Remove `#include <stdlib.h>' from the list; we should never
6397 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6398 resulting namespace pollution would cause other tests to fail.
6399 Configure scripts run with some older versions of g++ and HP's
6400 aCC would fail due to such an #include. Problems reported by
6401 Matthew Mueller in <http://bugs.debian.org/120704> and by
6402 Keith Bostic in
6403 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6404 In the test, use the test declaration before including <stdlib.h>,
6405 as that's closer to how it'll be used.
6407 2003-05-23 Akim Demaille <akim@epita.fr>
6409 * doc/autoconf.texi (Header Portability): ucred.h.
6410 From Ian Redfern.
6412 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6414 Overhaul Autotest's logging: generate separate log files
6415 in testsuite.dir/NNN/testsuite.log, and append them to
6416 testsuite.log instead of re-running the test verbosely.
6418 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6419 file descriptor, write 0 to at_status_file instead of setting
6420 at_status=0, initialize some new variables (at_status_file,
6421 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6422 to rerun the tests, instead append the at_group_log to the
6423 at_suite_log when a test fails.
6424 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6425 with the AS_MESSAGE_LOG_FD redirected to stdout.
6426 (AT_CLEANUP): save the output status in $at_status_file
6427 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6428 its original place.
6429 (AT_CHECK): since tests are run with a redirected stdout,
6430 and used to be re-run in verbose mode, turn some $at_verbose
6431 into echo, and don't redirect the output of testing stdout
6432 and stderr.
6434 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6435 the name of the debugging directory and information about
6436 its contents.
6438 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6440 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6441 parameter.

6553 and truncate.
6555 2003-05-06 Akim Demaille <akim@epita.fr>
6557 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6558 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6559 by aclocal.m4 is changed it might require the importing of another
6560 m4 extension file, i.e., aclocal must be run.
6562 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6563 (&parse_args): Use --force with aclocal if required and supported.
6564 (&autoreconf_current_directory): Use &run_aclocal.

6571 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6572 argument instead of a file name, so that the request file remains
6573 open during the whole autom4te run.
6574 ($icache_file): New.
6575 (&freeze): Lock the $icache_file.
6577 2003-04-29 Derek Price <derek@ximbiot.com>
6579 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6580 seperator with m4_append_uniq(). It doesn't work.
6581 (AT_CLEANUP): Add `;' to end of at_help_all.
6582 (AT_INIT): Allow --keywords to be specified more than once. When
6583 grepping $at_help_all for keywords, use the field and keyword
6584 seperators to ensure a complete keyword match. Alter at_prev handling
6585 to support the new --keywords behavior.
6587 2003-04-27 Karl Berry <karl@freefriends.org>
6589 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6590 align better with others. I also made some of the individual
6591 entries on one line, for brevity and to make it easier for me to
6592 sort my dir-example file in the Texinfo distribution :).
6594 2003-04-12 Jim Meyering <jim@meyering.net>

6640 which removed the main loop.
6641 Thanks to Akim Demaille.
6643 2003-03-29 Akim Demaille <akim@epita.fr>

6655 2003-03-28 Akim Demaille <akim@epita.fr>
6657 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest

6659 header causes problems.
6661 2003-03-28 Akim Demaille <akim@epita.fr>
6663 * tests/torture.at (Configuring subdirectories): Require aclocal
6664 1.4, otherwise the test fails, as it does support configure.ac.
6665 This fixes the "test 40 failed" bug reports.

6669 * doc/autoconf.texi (C Compiler): `#line' portability.

6736 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
6737 Tru64 make in the "target lookup" section.
6738 (Automake): Automake 1.5+ no longer requires special tools to be
6739 present on the developer's host.

6760 When constructing paths with IFS=:, quote the path. If we're

6784 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6785 format starting with "-".
6787 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6789 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6790 is not portable inside Makefile.
6792 2003-02-20 Akim Demaille <akim@epita.fr>
6794 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6795 compiler says yeah, but preproc says nope, compiler is right.
6796 Conversely, prompt the reader to send a bug report to the
6797 maintainers of the package, not of Autoconf.
6799 2003-02-20 Klee Dienes <kdienes@apple.com>
6801 * bin/autoreconf.in (autoreconf_current_directory): Properly

6812 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6813 innocuous variant befor including <limits.h> or <assert.h>. This
6814 works around a bug reported by Albert Chin: HP-UX 11i
6815 (and earlier versions) have a <limits.h> that declares
6816 gettimeofday and many other functions.
6818 2002-12-03 Paul Eggert <eggert@twinsun.com>
6820 Version 2.57.
6822 * NEWS, configure.ac: Update version.

6826 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6827 nontrivially in main's body, so that f's external declaration is
6828 not optimized away in AIX. This should fix the bug reported by
6829 Martin Frydl in
6830 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6832 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6833 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6834 defined, to support freestanding compilers. This should fix the
6835 bug reported by Momchil Velkov in
6836 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6838 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6839 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
6840 obsolete AC_CHECK_TYPE. The missing empty arg was reported
6841 by Simon Josefsson in
6842 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
6844 * Makefile.maint (www-gnu): New macro.
6845 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6846 the location has moved.
6848 2002-12-02 Martin Frydl <martin@systinet.com>
6850 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6851 \(.*\) match is too long and there is something more to be checked.
6852 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

6870 Update from masters.
6872 2002-11-14 Akim Demaille <akim@epita.fr>
6874 * Makefile.maint: Sync with Bison, i.e.:
6875 (po-check): Scan .l and .y files instead of the
6876 .c and the .h files that they generate. This fixes the bug
6877 reported by Tim Van Holder in:
6878 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6879 Look for N_ as well as for _. Try to avoid matching #define for
6880 N_ and _.
6881 From Paul Eggert.
6883 2002-11-14 Akim Demaille <akim@epita.fr>
6885 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6886 From Paul Eggert and Albert Chin-A-Young.
6888 2002-11-14 Akim Demaille <akim@epita.fr>
6890 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6891 From Paul Eggert and Albert Chin-A-Young.
6893 2002-11-14 Kevin Ryde <user42@zip.com.au>
6895 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6896 than assigning in main, to avoid HP cc +O3 optimizing it away.
6898 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6900 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6901 option. Process --recheck after parsing all options. Pass -q
6902 option to configure on --recheck.
6903 (AC_OUTPUT): Pass -q from configure to config.status.
6904 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6905 arguments to record.
6906 * doc/autoconf.texi (config.status Invocation): Document
6907 config.status -q option.
6909 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
6911 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
6912 Makefile.in if Makefile.am exists.

6932 -w.

6934 Reported by Ezra Peisach.
6936 2002-11-05 Akim Demaille <akim@epita.fr>
6938 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6939 Remove.
6940 We _have_ to stop using the old compatibility scheme that tried to
6941 avoid useless backslashes because Libtool 1.4.3 contains a
6942 AC_DEFINE([error_t], [int],
6943 [Define to a type to use for \`error_t' if it is not
6944 otherwise available.])
6945 We _have_ to quote the single quote and backslashes with \. The
6946 old compatibility scheme saw that ` was backslashed, and therefore
6947 did not quote the single quote. Hence before this patch, Autoconf
6948 was not compatible with Libtool.
6950 2002-11-04 Paul Eggert <eggert@twinsun.com>
6952 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6990 2002-10-31 Akim Demaille <akim@epita.fr>
6992 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6993 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6994 Make variable, not a shell variable.
6995 Suggested by Bruno Haible.
6997 2002-10-31 Akim Demaille <akim@epita.fr>
6999 * bin/autom4te.in (load_configuration): Reject #args out of any
7000 language.
7002 2002-10-31 Akim Demaille <akim@epita.fr>
7004 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

7016 Suggested by Tim van Holder.

7020 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
7021 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
7022 Problem reported by Bruno Haible.
7024 2002-10-29 Akim Demaille <akim@epita.fr>
7026 * doc/autoconf.texi (Header Templates): Put also in words what the
7027 pictures says to assist free style readers.
7028 (Customizing autom4te): s/--cache=/--cache /.
7030 2002-10-29 Akim Demaille <akim@epita.fr>

7338 longer required can still cause errors.
7339 Reported by Alexandre Duret-Lutz.
7341 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

7361 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7362 if some file was changed instead of `print'.
7363 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
7364 (&parse_args): Remove the dead options.
7365 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
7366 autoheader's quiet mode.
7367 (AT_CHECK_AUTOUPDATE): Likewise.
7368 * tests/tools.at (autoupdate): Adjust.
7369 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7371 2002-10-11 Akim Demaille <akim@epita.fr>
7373 No longer use CPP to check for the existing of headers: use CC to
7374 check for compilability.
7376 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
7377 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
7378 (_AC_CHECK_HEADER_NEW): Rename as...
7379 (AC_CHECK_HEADER): this.
7381 * lib/autotest/general.m4 (AT_INIT): Include the failed test
7382 numbers in the Subject suggestion.
7384 2002-10-11 Akim Demaille <akim@epita.fr>
7386 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
7387 Suggest using AC_CHECK_DECLS instead.
7389 2002-10-11 Akim Demaille <akim@epita.fr>
7391 * tests/torture.at (AC_ARG_VAR): Have configure report the value
7392 of `precious'.
7394 2002-10-11 Akim Demaille <akim@epita.fr>
7396 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
7397 file name to enable parallel executions.
7398 From Sam Varshavchik.
7400 2002-10-08 Akim Demaille <akim@epita.fr>
7402 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7403 aclocal invocation, as Gettext macros might not be visible to
7404 aclocal.
7405 Instead of blindly running autopoint, scan configure.ac (not the
7406 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7407 Reported by Paul D. Smith.
7409 2002-10-08 Paul Eggert <eggert@twinsun.com>
7411 Work around problems found when POSIXLY_CORRECT=1 is set.
7412 None of this seems to have anything to do with POSIX, really,
7413 but it's how Perl getopt works.
7414 * bin/autom4te.in (parse_args): Configure GetOpt with
7415 "permute", too.
7416 * doc/autoconf.texi (Invoking autom4te):
7417 --warning -> --warnings.
7418 * lib/autom4te.in: --warning -> --warnings.
7420 2002-09-28 Akim Demaille <akim@epita.fr>
7422 * doc/autoconf.texi (autom4te.cache): New section.
7424 2002-09-28 Akim Demaille <akim@epita.fr>
7426 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
7427 (Automake-preselections): Update.
7428 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
7430 2002-09-28 Akim Demaille <akim@epita.fr>
7432 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
7433 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
7434 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7435 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
7437 2002-09-28 Akim Demaille <akim@epita.fr>
7439 * tests/torture.at (Configuring subdirectories): Be robust to
7440 users who use config.site to require for a cache: in this case,
7441 the two last configure runs, using two different sets of
7442 arguments, trigger a legitimate error.
7444 2002-09-28 Akim Demaille <akim@epita.fr>
7446 * tests/m4sh.at (Functions Support, Functions and return Support):
7447 New.
7449 2002-09-28 Akim Demaille <akim@epita.fr>
7451 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
7452 autoheader are Perl programs.
7453 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
7454 (autom4te): Specify that the sources are in the $srcdir.
7455 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7457 2002-09-28 Akim Demaille <akim@epita.fr>
7459 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
7460 (tm_zone): Move their rules to...
7461 * lib/autoconf/types.m4: here, using AN_ macros.
7462 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7463 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7464 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7465 * lib/autoconf/programs.m4: here.
7466 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
7467 (ETAGS_FOR_AUTOCONF): New.
7468 Use it.
7470 2002-09-28 Akim Demaille <akim@epita.fr>
7472 * lib/autoconf/autoscan.m4: New file.
7473 * lib/autoconf/autoconf.m4: Include it.
7474 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
7475 that were listed in the original autoscan.list.
7476 * lib/autoconf/headers.m4: Similarly with headers.
7477 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7478 (.m4.m4f): Don't pass --prepend-include, since that's done by
7479 tests/autom4te itself.
7480 * lib/autoscan/Makefile.am: Include freeze.mk.
7481 (autoscan.list): New target --this file is no longer a source.
7482 (autoscan.pre): New file.
7484 2002-09-28 Akim Demaille <akim@epita.fr>
7486 * bin/autoscan.in (@kinds): Make them singular.
7487 Adjust all uses.
7488 (&init_tables): When --debug, report the list of rules to ease
7489 tracking changes in autoscan.list.
7490 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7492 2002-09-28 Akim Demaille <akim@epita.fr>
7494 * lib/autoscan/functions, lib/autoscan/headers,
7495 * lib/autoscan/identifiers, lib/autoscan/makevars,
7496 * lib/autoscan/programs: Merge into...
7497 * lib/autoscan/autoscan.list: this.
7498 * bin/autoscan.in (&init_tables): Adjust.
7500 2002-09-28 Akim Demaille <akim@epita.fr>
7502 * lib/autoscan/functions, lib/autoscan/headers,
7503 * lib/autoscan/identifiers, lib/autoscan/makevars,
7504 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7505 `functions' line is now prefixed with `function:'.
7506 * bin/autoscan.in (&init_tables): Adjust.
7508 2002-09-28 Akim Demaille <akim@epita.fr>
7510 From now on, autoscan files must always map a macro name to a
7511 word: there is no `default' macro for autoscan.
7513 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7514 all.
7515 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7516 explicit.
7518 2002-09-28 Akim Demaille <akim@epita.fr>
7520 * bin/autoscan.in (%c_keywords): Remove.
7521 (&used): Keep only track of the words we might be interested in.
7522 (&output_kind): It is no longer needed to look for non active
7523 checks.
7525 2002-09-27 Akim Demaille <akim@epita.fr>
7527 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
7528 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
7529 * lib/autoscan/functions: Adjust.
7530 * doc/autoconf.texi (Particular Functions): Adjust.
7532 2002-09-27 Akim Demaille <akim@epita.fr>
7534 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
7535 from /tmp.
7536 Thanks to Bill Moseley and Paul Eggert.
7537 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
7538 the tmpdir must be created.
7539 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
7540 dir be in the build tree, instead of $TMPDIR.
7542 2002-09-27 Akim Demaille <akim@epita.fr>
7544 * bin/autoscan.in: Improve the comments.
7545 (&parse_args): Drop obsolete undocumented options.
7546 (&output_kind): Output warnings.
7547 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
7548 (getwd): Trigger a warning.
7550 2002-09-26 Akim Demaille <akim@epita.fr>
7552 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7553 Reported by Ralf Corsepius.
7554 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7556 2002-09-26 Akim Demaille <akim@epita.fr>
7558 Single suffix rules and seperated dependencies are not portable.
7560 * doc/autoconf.texi (Installation Directory Variables): Update.
7561 (Limitations of Make): Some about `Single Suffix Rules and
7562 Separated Dependencies'.
7563 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7564 (ifnames, autoscan, autom4te): Un-factor into several rules.
7566 2002-09-25 Paul Eggert <eggert@twinsun.com>
7568 * BUGS (Interoperability bugs): New section. Mention libtool
7569 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7571 2002-09-24 Paul Eggert <eggert@twinsun.com>
7573 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7574 make handles suffix-rules differently from GNU make.
7576 * bin/Makefile.am (SUFFIXES, .in): Remove.
7577 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7578 Move the body of the old .in rule here.
7580 2002-09-16 Akim Demaille <akim@epita.fr>
7582 i960 compilers create `b.out' files by default.
7583 Reported by Ralf Corsepius.
7585 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7586 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7588 2002-09-13 Paul Eggert <eggert@twinsun.com>
7590 * doc/autoconf.texi (Particular Headers): Remove obsolete
7591 reference to `struct timezone' in the description of
7592 AC_HEADER_TIME.
7594 2002-09-13 Akim Demaille <akim@epita.fr>
7596 Version 2.54.
7598 * config/config.sub, config/config.guess: Update.
7599 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7600 * Makefile.am: Adjust.
7602 2002-09-13 Akim Demaille <akim@epita.fr>
7604 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7605 reading config.log when the compiler is rejected.
7606 Suggested by Guido Draheim.
7608 2002-09-13 Akim Demaille <akim@epita.fr>
7610 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7611 (chdir_init) might hang when stat'ing mounted directories.
7612 Reported by Vance Shipley.
7614 2002-09-12 Akim Demaille <akim@epita.fr>
7616 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7617 the lists.
7619 2002-09-12 Akim Demaille <akim@epita.fr>
7621 * doc/autoconf.texi (Defining Symbols): Present two different
7622 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7623 difference between 1 argument calls, and 2-3 argument calls.
7625 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7627 * doc/autoconf.texi: Review grammar and punctuation.
7629 2002-09-11 Paul Eggert <eggert@twinsun.com>
7631 * doc/autoconf.texi: Fix minor formatting, spelling, and
7632 grammatical typos.
7633 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7634 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7635 is obsolescent.
7637 2002-09-11 Akim Demaille <akim@epita.fr>
7639 * doc/autoconf.texi (Questions): Rename as...
7640 (FAQ): this.
7641 (Defining Directories): New.
7643 2002-09-09 Akim Demaille <akim@epita.fr>
7645 * doc/autoconf.texi (Making testsuite Scripts): Update.
7646 Suggested by Nishio Futoshi.
7648 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7650 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7651 plain `@' is wanted.
7653 2002-09-09 Akim Demaille <akim@epita.fr>
7655 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7656 `duplicates', since the algorithm was too naive and could keep
7657 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7658 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7659 Reported by Ralf Corsepius.
7660 * tests/torture.at (Configuring subdirectories): Exercise these
7661 cases.
7663 2002-09-09 Akim Demaille <akim@epita.fr>
7665 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7666 looking for a replacement file.
7667 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7668 directory is relative.
7669 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7670 directory definition.
7671 Reported by Andreas Schwab and Jim Meyering.
7673 2002-09-06 Akim Demaille <akim@epita.fr>
7675 * doc/autoconf.texi (Setting Output Variables): Clarify what
7676 precious variables are.
7677 Suggested by Pontus Skoeld.
7679 2002-09-05 Akim Demaille <akim@epita.fr>
7681 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7682 (ifnames, autoscan, autom4te): Since we don't only depend on
7683 configure.ac variables (such as VERSION etc.), but also on prefix
7684 and so forth, depend on Makefile, not configure.ac.
7685 Reported by Alexandre Duret-Lutz.
7686 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7688 2002-09-05 Kevin Ryde <user42@zip.com.au>
7690 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7691 doesn't seem to be confined to ia64, just say "some versions".
7693 2002-09-04 Akim Demaille <akim@epita.fr>
7695 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7696 Automake 1.6c.
7697 * Makefile.am (maintainer-clean-local): Remove.
7698 (MAINTAINERCLEANFILES): Remove COPYING.
7700 2002-09-03 Paul Eggert <eggert@twinsun.com>
7702 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7703 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7704 Brinkmann.
7706 2002-09-03 Akim Demaille <akim@epita.fr>
7708 * configure.ac: Bump to 2.53d.
7709 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7710 as of today, on Automake's team suggestion.
7712 2002-09-03 Akim Demaille <akim@epita.fr>
7714 Version 2.53c.
7716 2002-09-02 Akim Demaille <akim@epita.fr>
7718 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7719 SITE_MACRO_DIR.
7720 * configure.ac: Disable SITE_MACRO_DIR.
7722 2002-09-02 Jim Meyering <meyering@lucent.com>
7724 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7725 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7726 Also, tweak grammar: s/make sure to/be sure to/.
7728 2002-09-02 Paul Eggert <eggert@twinsun.com>
7730 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7731 directory names are generally preferable to physical names.
7733 2002-09-02 Akim Demaille <akim@epita.fr>
7735 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7736 Reported by Raja R. Harinath.
7737 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7738 * bin/autoupdate.in: Use error instead of die.
7740 2002-09-01 Paul Eggert <eggert@twinsun.com>
7742 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7743 ordinary shell concatenation rather than echo+tr+sed command that
7744 runs afoul of a long-line-related sed bug in Solaris 8.
7746 * bin/autoheader.in (parse_args): --warning -> --warnings.
7748 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7749 stdout, as traditional "ls" does.
7750 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7751 _AC_COMPILER_EXEEXT_O): Likewise.
7752 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7754 * bin/autoconf.as: Add --prepend-include option. This patch was
7755 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7756 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7758 * bin/autoconf.in, configure: Regenerate.
7760 * doc/autoconf.texi (Special Shell Variables): Mention
7761 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7763 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7764 MAILPATH and set PS1, PS2, PS4 to default values, to work
7765 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7766 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7767 the Autoconf documentation specifies; fall back to "unset" only if
7768 this fails. Use a shell for-loop for this rather than an m4 loop,
7769 to shorten the output script.
7771 2002-08-30 Paul Eggert <eggert@twinsun.com>
7773 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7774 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7775 for the CDPATH problem. Document PWD.
7776 (Limitations of Builtins): Document the problem that "cd $foo" and
7777 "ls $foo" may refer to different directories in shells conforming
7778 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7779 example, since the old example is now out of date.
7781 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7782 FOO" and "ls FOO" talk about different directories; this catches
7783 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7784 spaghetti.
7786 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7787 of rolling our own unset.
7788 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7789 in practice we needn't worry about CDPATH if unset doesn't work.
7791 * Makefile.in, aclocal.m4, bin/Makefile.in,
7792 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7793 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7794 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7795 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7796 tests/Makefile.in: Regenerate with Automake 1.6.3.
7798 * config/config.guess, config/config.sub, config/mkinstalldirs:
7799 Update.
7801 * configure: Regenerate with self.
7803 2002-08-30 Kevin Ryde <user42@zip.com.au>
7805 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7806 default output.
7808 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7810 * bin/autom4te.in (Request::load): Correctly test for "do" read
7811 failure.
7813 2002-08-29 Akim Demaille <akim@epita.fr>
7815 * lib/Autom4te/General.pm (&xqx): New.
7816 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7817 hand, which is not portable.
7818 (&error): New.
7819 * bin/autom4te.in: Use them.
7820 Use &error instead of die.
7821 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7822 Adjust.
7824 2002-08-17 Paul Eggert <eggert@twinsun.com>
7826 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7827 default list of compilers to try, since it was long ago superseded
7828 by the ksh fc builtin. Suggested by Steven G. Johnson.
7830 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7832 * doc/autoconf.texi (Invoking autom4te): End the option table,
7833 fixing a bug introduced by the previous patch.
7834 (Limitations of Make): Add a 'target lookup' subentry in the
7835 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7837 2002-07-29 Mark D. Roth <roth@feep.net>
7839 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7840 options and use $AUTOM4TE_PATH.
7841 * doc/autoconf.texi: Remove documentation of autom4te
7842 --include-envvar and --site-macro-subdir options and document
7843 use of $AUTOM4TE_PATH.
7844 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7845 arguments from each language section.
7847 2002-07-29 Paul Eggert <eggert@twinsun.com>
7849 * doc/install.texi: Include copyright symbol in copyright notice.
7851 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7852 Replace with:
7853 (AM_MAKEINFOFLAGS): New macro.
7854 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7855 * Makefile.am (INSTALL): Use the new macros.
7856 Use -o rather than --output, since "missing" does not grok --output.
7858 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7860 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7861 comments do not always work. Never trust the exit status of
7862 `make -k'.
7864 2002-07-24 Kevin Ryde <user42@zip.com.au>
7866 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7867 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7869 2002-07-23 Paul Eggert <eggert@twinsun.com>
7871 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7872 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7873 apparently treats PATH="nonexistent" as if it contained ".".
7874 Bug reported by Stefan `Sec' Zehl.
7876 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

7996 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
7997 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
7998 so that Emacs setups GNU style for perl-mode and cperl-mode.
8000 2002-06-27 Paul Eggert <eggert@twinsun.com>
8002 * config/install-sh: Quote $src. Prefer || to test's -o option,
8003 as per "Limitations of Builtins".
8004 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
8005 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8007 * tests/mktests.sh: Use grep instead of fgrep, as per
8008 "Limitations of Builtins".
8010 2002-06-15 Paul Eggert <eggert@twinsun.com>
8012 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,

8014 so that we consistently test the just-built programs.
8015 * tests/wrappl.as: Likewise.

8029 on Solaris 2.5.1.
8031 2002-06-11 Andreas Schwab <schwab@suse.de>

8035 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
8037 * bin/autom4te.in ($cache): Don't define using `$me', the name
8038 of the cache should not depend on the name under which autom4te
8039 was installed.
8041 2002-06-07 Akim Demaille <akim@epita.fr>
8043 * tests/tools.at (autoconf: forbidden tokens, basic)

8045 words in autom4te.in.
8047 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8049 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
8050 _AC_LANG_PROGRAM_C_F77_HOOKS.
8052 2002-06-07 Akim Demaille <akim@epita.fr>

8055 rename as...

8058 AC_FUNC_FNMATCH_GNU.
8060 2002-06-07 Akim Demaille <akim@epita.fr>
8062 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
8063 Rosetta Stone for Unix.
8065 2002-06-07 Akim Demaille <akim@epita.fr>
8067 * bin/autom4te.in (warn_forbidden): When rejecting a token,
8068 suggest m4_pattern_allow.
8069 Suggested by Adam J. Richter.
8071 2002-06-07 Akim Demaille <akim@epita.fr>
8073 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
8074 ac_config_libobj_dir.
8075 (AC_CONFIG_LIBOBJ_DIR): New.
8076 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
8077 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
8078 Use ac_config_libobj_dir to find the replacement files.
8079 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
8080 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)

8083 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
8084 * tests/mktests.sh (ac_exclude_list): Don't check

8087 2002-06-06 Paul Eggert <eggert@twinsun.com>
8089 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
8090 if ln doesn't work.
8091 * NEWS: Likewise.
8092 * doc/autoconf.texi (Configuration Links): Likewise.

8130 version of Autoconf that is discussed.
8132 2002-05-22 Paul Eggert <eggert@twinsun.com>
8134 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8135 from the default list of compilers to try. Suggested by
8136 Kate Hedstrom.
8137 * NEWS: Document the above.
8138 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8140 2002-05-17 Paul Eggert <eggert@twinsun.com>
8142 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8143 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8144 This improves on an earlier suggestion by H. Peter Anvin.
8146 2002-05-16 Paul Eggert <eggert@twinsun.com>
8148 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8149 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8150 Both macros now accept an optional source-dir arg.
8151 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8153 * NEWS: Document this.
8154 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8156 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8157 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8158 not for GNU extensions; this undoes part of the 2000-11-03 change,
8159 reverting to 2.13-compatible behavior.
8160 Add new optional argument DIR.
8161 (AC_FUNC_FNMATCH_GNU): New macro.
8163 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8165 2002-05-08 Paul Eggert <eggert@twinsun.com>
8167 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8168 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8169 and it causes a 'test' syntax error if it fails.
8170 Bug reported by Stephen Gildea.
8172 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8173 If prototypes are supported, use them to check this at compile-time,
8174 instead of trying to check it at run-time. If we must do a run-time
8175 check, assume that setvbuf is standard when cross-compiling, as
8176 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8177 Bug reported by Paul D. Smith.
8179 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8180 argument specifying location of getloadavg.c. This removes a
8181 FIXME. This idea was taken from Jim Meyering's implementation in
8182 textutils.
8183 * doc/autoconf.texi (Particular Functions): Document this.
8184 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8185 that's what the code does; this fixes a bug reported by
8186 Paul D. Smith.
8188 2002-05-03 Akim Demaille <akim@epita.fr>
8190 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8191 autopoint instead of gettextize.
8192 ($uses_alocal): Rename as...
8193 ($uses_aclocal): this.
8194 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8195 Suggested by Bruno Haible.
8197 2002-05-03 Akim Demaille <akim@epita.fr>
8199 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8201 2002-04-29 Paul Eggert <eggert@twinsun.com>
8203 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8204 files to be 1 second older; just set them to be the same time.
8205 Also, sleep 1 second after the first aclocal, to work around
8206 problems with sub-second time stamps on the input files.
8208 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8210 * doc/autoconf.texi: Mention "set -e -x" lossage
8211 under node "Limitations of Builtins".
8213 2002-04-29 Akim Demaille <akim@epita.fr>
8215 * doc/install.texi: Better wording for setting variables when
8216 running configure.
8217 From Christian Cornelssen.
8219 2002-04-29 Akim Demaille <akim@epita.fr>
8221 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8222 of lack of $LINENO support, then the test will compare the $LINENO
8223 in testsuite vs. the lineno in the test file. This is wrong, of
8224 course.
8225 Be sure to protect it.
8226 Reported by Patrick Welche.
8228 2002-04-25 Akim Demaille <akim@epita.fr>
8230 * doc/autoconf.texi (Obsolete Macros): Typo.
8231 Reported by Vladimir Volovich.
8233 2002-04-25 Akim Demaille <akim@epita.fr>
8235 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8236 than some of the input files, hence, on the second run of aclocal,
8237 if some of its input are younger, make them older.
8238 Suggested by Paul Eggert.
8240 2002-04-25 Akim Demaille <akim@epita.fr>
8242 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8243 Thanks to Paul Eggert.
8245 2002-04-25 Akim Demaille <akim@epita.fr>
8247 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8248 and ac_subst_vars be sh variables containing the list of
8249 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8250 DEFAULT diversion.
8251 (_AC_INIT_PREPARE): Use them to log them.
8252 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8253 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8254 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8255 _AC_SUBST_FILES and _AC_SUBST_VARS.
8256 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8258 2002-04-24 Akim Demaille <akim@epita.fr>
8260 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8261 autoheader, so that automake does not complain about a missing
8262 config.h.in that was to be created.
8264 2002-04-23 Akim Demaille <akim@epita.fr>
8266 * bin/autoheader.in (parse_args): --warning takes an argument.
8267 Fixes PR/220.
8269 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
8271 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

8286 Reported by Gregory Giannoni.
8288 2002-04-22 Akim Demaille <akim@epita.fr>
8290 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.

8318 * doc/autoconf.texi: Follow the outline suggested in the GNU
8319 Sample Texts sections of the Texinfo 4.2 manual. Most
8320 importantly, this makes sure that the copyright notices appear in
8321 all output formats. You probably need Texinfo 4.2 to generate

8346 that is not portable to Zsh.
8348 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8350 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8351 from aclocal.m4 too.
8353 2002-04-12 Akim Demaille <akim@epita.fr>
8355 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
8357 2002-04-10 Akim Demaille <akim@epita.fr>
8359 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8360 workaround for ${1+"$@"}.
8361 * doc/autoconf.texi (Shell Substitutions): Explain it.
8362 From Oliver Kiddle and Peter Stephenson.
8364 Have M4sh perform minimal shell sanitizing.
8366 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8367 part into...
8368 (_AS_PREPARE): this new macro.
8369 (AS_PREPARE): New.
8370 (AS_INIT): Invoke AS_SHELL_SANITIZE.
8371 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8373 Adjust Autoconf and Autotest.

8376 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8377 * lib/autotest/general.m4 (AT_INIT): Likewise.
8378 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8379 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8380 AS_SHELL_SANITIZE.
8382 Use this M4sh to generate Autoconf's shell scripts.
8384 * tests/wrapsh.as: New, precursor of wrapsh.in.
8385 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8386 on Autotest and M4sh.
8387 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8388 (wrapsh.in): New target.
8389 * bin/autoconf.as: New, precursor of autoconf.in.
8390 (autoconf.in): New target.
8392 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
8394 * doc/autoconf.texi (Limitations of Make): Mention the issue
8395 with indented comments in rules.

8405 (Portable Shell): Cross reference to Systemology.
8407 2002-04-05 Akim Demaille <akim@epita.fr>
8409 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8410 directories when descending in a SUBDIRS.
8411 Reported by Ezra Peisach.
8413 2002-04-04 Andreas Schwab <schwab@suse.de>
8415 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8416 contains no literal separators.
8418 2002-04-03 Akim Demaille <akim@epita.fr>
8420 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8421 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8422 Use dnl, not the KILL diversion.
8423 Extracted from...
8424 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8425 (AC_CONFIG_LINKS): here.
8426 Adjust.
8427 Don't use the KILL diversion, as it kills spurious output, which
8428 results in failures being hidden.
8429 Use m4_defn where appropriate.
8430 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8431 after the second argument.
8432 Use m4_defn.
8433 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8434 syntax, as it is provided by M4sugar.

8458 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.

8460 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
8461 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
8462 (AC_C_CONST): Same.

8476 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8477 to avoid versions of HP C which don't allow that.
8479 2002-03-27 Paul Eggert <eggert@twinsun.com>
8481 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8482 (AS_SHELL_SANITIZE): Invoke it.

8489 2002-03-26 Akim Demaille <akim@epita.fr>
8491 * doc/autoconf.texi (Introduction): The GNATS base moved.
8493 2002-03-25 Paul Eggert <eggert@twinsun.com>
8495 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8496 as POSIX requires, as it doesn't work with Zsh.
8497 * doc/autoconf.texi (Assignments): Document the problem.
8499 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8501 * doc/autoconf.texi (Limitations of Make): Mention more issue
8502 about VPATH, overriding of macros in sub-makes, and handling of
8503 SHELL.
8505 2002-03-21 Paul Eggert <eggert@twinsun.com>
8507 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8508 problem with here-document buffer boundaries.
8510 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8511 when reinvoking the shell, to work around problems with installers
8512 who put strange things like "cd" commands in their environments.
8514 2002-03-19 Akim Demaille <akim@epita.fr>
8516 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8517 From Aaron Ucko.
8519 2002-03-19 Akim Demaille <akim@epita.fr>
8521 * bin/autoscan.in (scan_file): Specify the location in `&used'
8522 invocations.
8523 From Nicolas Joly.
8525 2002-03-19 Akim Demaille <akim@epita.fr>
8527 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8528 From Nishio Futoshi.
8530 2002-03-19 Akim Demaille <akim@epita.fr>
8532 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

8536 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8537 (Limitations of Usual Tools): Add mkdir section.
8539 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8540 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8541 back on AS_DIRNAME to compute prefixes otherwise; this is
8542 roughly what mkinstalldirs does. That way, we need not have
8543 our own filename disassembler. The old disassembler did not
8544 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8546 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8547 Create at_test_all by a series of assignments,
8548 not by a single assignment of a long string. The latter causes ksh
8549 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8550 presumably because of a buffer overrun.
8552 2002-03-14 Paul Eggert <eggert@twinsun.com>
8554 * lib/autotest/general.m4 (at_times_skip):
8555 Renamed from at_times. Now a boolean.
8556 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8557 says 'times: not found'.
8559 2002-03-14 Akim Demaille <akim@epita.fr>
8561 * bin/autoreconf.in (&study_gettextize): New.
8562 (&autoreconf): Handle newest gettextize.
8563 Rerun aclocal if needed.
8564 Suggested by Andreas Schwab.
8566 2002-03-13 Akim Demaille <akim@epita.fr>

8573 Add information about stdint.h and inttypes.h from Paul Eggert.
8575 2002-03-13 Akim Demaille <akim@epita.fr>
8577 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8578 -p'.
8579 From Bob Proulx.
8581 2002-03-12 Akim Demaille <akim@epita.fr>
8583 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8584 m4_require.
8586 2002-03-11 Andreas Schwab <schwab@suse.de>
8588 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8589 does not do it if --with-lispdir is given.
8591 2002-03-08 Akim Demaille <akim@epita.fr>
8593 Version 2.53.
8595 2002-03-08 Akim Demaille <akim@epita.fr>
8597 * doc/autoconf.texi (Subdirectories): Clarify that the
8598 subdirectory should exist.
8600 2002-03-08 Akim Demaille <akim@epita.fr>
8602 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8604 2002-03-08 Akim Demaille <akim@epita.fr>
8606 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8607 aliases the actual variables, and modifications of the former
8608 affect the latter.
8610 2002-03-08 Akim Demaille <akim@epita.fr>
8612 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8613 because of C-c: have m4 output in tmp files, then mv them.
8615 2002-03-08 Akim Demaille <akim@epita.fr>
8617 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8618 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8619 * bin/ifnames.in: Copyright update.

8625 2002-03-05 Akim Demaille <akim@epita.fr>
8627 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8628 Kevin Ryde.
8630 2002-03-05 Akim Demaille <akim@epita.fr>

8634 2002-03-04 Akim Demaille <akim@epita.fr>
8636 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8637 * lib/autoconf/general.m4 (AC_INIT): More informative error
8638 message for LIBOBJ.
8640 2002-03-04 Akim Demaille <akim@epita.fr>
8642 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8643 parallel builds.
8645 2002-03-04 Akim Demaille <akim@epita.fr>
8647 * doc/autoconf.texi (Transforming Names): Equality between target
8648 and host is irrelevant.
8649 (Specifying Names, Canonicalizing): Remove all references to the
8650 backward compatibility hooks. Rather, collect them all into...
8651 (Hosts and Cross-Compilation): this new section.
8652 * doc/install.texi (System Type): Ditto.
8653 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8654 that `--host' implies cross-compilation.
8656 2002-03-04 Akim Demaille <akim@epita.fr>
8658 * doc/autoconf.texi (Evaluation Macros): New.
8659 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8660 useless.
8661 (_m4_foreach): Define the variant with immediate evaluation so
8662 that it contains exactly the items, not an expression which
8663 evaluation is the current item.
8664 (m4_re_string, m4_re_word): Don't over quote them.
8666 2002-03-04 Akim Demaille <akim@epita.fr>
8668 Instead of having stacking `shift's evaluated at the end, let
8669 `foreach' loops immediately evaluate them.
8671 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8672 $*. This is the n-th time I change my mind, but hopefully this is
8673 the last...
8674 (m4_lquote): New.
8675 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8676 efficient.
8677 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8678 it was only a hack for m4_text_wrap.
8679 (m4_car2): Remove, replaced by...
8680 (m4_cdr): New.
8681 (_m4_foreach): Adjust.
8682 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8683 m4_bpatsubst for clarification.

8735 AC_PREFIX_PROGRAM fails with dashed program names
8737 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8738 variable when looking for the prefix program.
8739 Now it also works for shell variables.

8744 case/esac.

8749 case/esac, some shells don't support it.
8750 Reported by Zack Weinberg.

8772 to this file.
8774 2002-02-05 Akim Demaille <akim@epita.fr>
8776 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

8798 * bin/autom4te.in (&parse_args): Implement `frozen files are
8799 optional are the sum of the previous files on the command line'.
8800 Also, pass `--reload-state=' on them, so...
8801 (handle_m4): don't.
8802 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8803 (M4sh): Rely on M4sugar.

8809 * doc/autoconf.texi (Initializing configure): Adjust.
8811 2002-01-30 Akim Demaille <akim@epita.fr>
8813 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8814 alphanumeric to `-' instead of `_'.
8816 2002-01-30 Akim Demaille <akim@epita.fr>
8818 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8819 for plain code, the other for cross-compilation code. The latter
8820 is now run with GCC only.
8821 * doc/autoconf.texi (Compilers and Preprocessors): New.
8823 2002-01-30 Akim Demaille <akim@epita.fr>
8825 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8826 values.
8827 * doc/autoconf.texi (Initializing configure): Explain how to
8828 change AC_INIT default values.
8830 2002-01-29 Akim Demaille <akim@epita.fr>
8832 * tests/torture.at (Configuring subdirectories): Use configure.in,
8833 so that aclocal 1.4 works.
8834 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8836 2002-01-28 Akim Demaille <akim@epita.fr>
8838 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8839 needs an argument.
8841 2002-01-28 Akim Demaille <akim@epita.fr>
8843 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8844 AUTOTEST_PATH *after* it was set.
8845 Don't put `.' in the PATH: the user should be precise and `./' if
8846 needed. In addition, given that the test suite does some `cd', if
8847 `.' is in the path, the `tested programs' sections will report
8848 programs found in the test suite's directory, while during the
8849 tests (performed in their own directory), these programs are no
8850 longer visible. In other words, the results is confusing and
8851 useless.
8852 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8854 2002-01-24 Akim Demaille <akim@epita.fr>
8856 Version 2.52g.

8917 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8918 package.m4, since is really depends upon configure.ac, not
8919 configure.
8920 * doc/autoconf.texi (testsuite Scripts): Adjust.
8921 * tests/Makefile.am (package.m4): New.
8922 EXTRA_DIST it since its a source.
8924 2002-01-06 Akim Demaille <akim@epita.fr>
8926 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8927 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8928 and PACKAGE_BUGREPORT from here...
8929 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8930 arguments.
8931 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8932 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8933 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8934 * tests/tools.at (autoheader): Adjust.
8935 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

8950 sometimes needing writable input.
8952 2001-12-17 Jim Meyering <meyering@lucent.com>
8954 * doc/autoconf.texi (New Macros): Tweak wording.
8956 2001-12-14 Akim Demaille <akim@epita.fr>
8958 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8959 trailing files, don't apply `-rf' to files which might not be
8960 created by configure (core, core.*, and *.core), but just `rm -f'.
8961 Suggested by Jonathan Kamens.
8963 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8965 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8967 2001-12-14 Akim Demaille <akim@epita.fr>
8969 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8971 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

8974 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8975 abs_srcdir, top_srcpath to abs_top_srcdir.
8976 (_AC_OUTPUT_FILES): Adjust.
8977 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8978 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8979 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8981 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8983 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed

8985 search path from the LPATH line in the $F77 -v output.
8987 2001-12-12 Kevin Ryde <user42@zip.com.au>
8989 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8990 forbidden file descriptors table.
8992 2001-11-26 Akim Demaille <akim@epita.fr>
8994 * bin/autoscan.in (%c_keywords): Build it at top level.
8995 Map to 1 in order to simplify its uses.
8997 2001-11-26 Akim Demaille <akim@epita.fr>
8999 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9000 Remove $filepath, useless.
9001 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9002 variables, they are really part of the tokens.
9003 Split the input line on spaces and then look for tokens.
9004 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9005 because of `lex$U.$(OBJEXT)'.
9006 (&scan_files): Use "@list" instead of join.
9007 * doc/Makefile.am (CLEANFILES): Add *.fns.
9009 2001-11-26 Akim Demaille <akim@epita.fr>

9016 * lib/autoscan/headers: errno.h is portable.
9018 2001-11-26 Akim Demaille <akim@epita.fr>
9020 * bin/autoscan.in (used): New.
9021 Use it.
9023 2001-11-26 Akim Demaille <akim@epita.fr>
9025 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9026 directives.
9027 (&scan_sh_file): Remove a duplicate pattern.
9028 (&check_configure_ac): Use long options.
9029 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9031 2001-11-26 Akim Demaille <akim@epita.fr>
9033 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9034 Before, having a line containing the opening of a multi line
9035 comment made the whole line be ignored.
9037 2001-11-26 Akim Demaille <akim@epita.fr>
9039 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9040 (testsuite Scripts): Be one of its subsection.
9041 (Autotest Logs): New.
9043 2001-11-26 Akim Demaille <akim@epita.fr>
9045 Test groups are now run two directories deeper.
9047 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9048 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9049 at_top_builddir.
9050 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9051 top_srcdir, builddir and top_builddir.
9052 Use `at_*dir' relatively to the directory containing the
9053 suite, use `*dir' when relatively to the current group dir.
9055 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9057 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9058 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9059 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9060 spelling errors.
9062 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9064 * doc/autoconf.texi (Using System Type): Add an example of `case
9065 $host' usage so people quit using `case $target' everywhere.
9067 2001-11-22 Akim Demaille <akim@epita.fr>
9069 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9070 spotted by Jim Meyering.
9072 2001-11-16 Paul Eggert <eggert@twinsun.com>
9074 This patch implements a `long double' suggestion by Oliver Kiddle.
9076 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9077 static, to catch errors if the value isn't known at compile-time
9078 and the compiler supports dynamic arrays. Change its name from
9079 `_array_' to `test_array' to avoid potential name clashes.
9080 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9081 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9082 better than double. Catch a bug in GCC 2.95.2 x86.
9083 * doc/autoconf.texi (C Compiler): Document the above.
9084 * NEWS: Likewise.
9086 2001-11-13 Akim Demaille <akim@epita.fr>
9088 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9089 hand.
9090 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9092 2001-11-13 Akim Demaille <akim@epita.fr>
9094 * lib/autotest/general.m4 (AT_INIT): After having run the test
9095 group, go back to the initial directory, not to at_suite_dir.
9097 2001-11-13 Akim Demaille <akim@epita.fr>
9099 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9100 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9101 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9102 option.
9103 (AT_CHECK_CONFIGURE): Use absolute paths.
9104 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9105 The problem is still the old one: there is no means in M4 (that I
9106 know about) to create a defining macro, because there is no means
9107 to create `$1' etc., therefore, the defining macro ``swallows''
9108 all the arguments meant to the defined macro.
9110 2001-11-13 Akim Demaille <akim@epita.fr>
9112 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9113 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9114 configure.ac.
9115 * tests/aclocal.m4: Remove, as it is no longer used.
9117 2001-11-13 Akim Demaille <akim@epita.fr>
9119 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9120 variable names when referring to a single test group, or to
9121 `suite' when referring to the whole test suite.
9122 `at_last_test' is removed: m4 compute at_format itself.
9123 (at_stdout, at_stder1, at_stderr): New variables.
9124 (AT_CHECK): Use them.
9126 2001-11-13 Akim Demaille <akim@epita.fr>
9128 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9129 in PATH.
9130 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9131 Do it as soon as a test fails, don't wait till the end of the test
9132 suite.
9133 Don't remove $as_me.[0-9]*, since these files no longer exist.
9135 2001-11-13 Akim Demaille <akim@epita.fr>
9137 * tests/tools.at: Use absolute paths, since we are no longer run
9138 in place.
9140 2001-11-13 Akim Demaille <akim@epita.fr>
9142 Now that tests are running in their own private dir, there is no
9143 need to list the files to remove at the end of tests groups.
9145 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9146 (AT_data_files, at_data_files): Remove.
9147 (AT_CLEANUP, AT_DATA): Simplify.
9148 (AT_INIT): Adjust.
9149 Remove the group dir if !debug && !failed.
9150 * tests/atspecific.m4: Adjust.
9152 2001-11-13 Akim Demaille <akim@epita.fr>
9154 Start a new layout for Autotest: `testsuite' creates
9155 `testsuite.dir' in which the at-check-line etc. files are to be
9156 found, and `testsuite.dir/003' where the test group 3 is run.
9158 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9159 at_check_line_file, at_format, at_test_normalized, at_group_dir
9160 are new variables.
9161 Create the directories.
9162 Use absolute paths for at- files.
9163 (AT_CHECK): Adjust.
9165 2001-11-11 Michael Matz <matz@kde.org>
9167 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9168 (m4_car2): New.
9169 (m4_car): Properly quote arguments.
9171 2001-11-13 Akim Demaille <akim@epita.fr>
9173 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9174 with stricter rules on LIBOBJS.
9176 2001-11-12 Paul Eggert <eggert@twinsun.com>
9178 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9179 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9180 __PROTOTYPES too.
9182 2001-11-12 Akim Demaille <akim@epita.fr>
9184 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9186 2001-11-12 Akim Demaille <akim@epita.fr>
9188 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9189 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9190 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9191 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9192 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9193 specify to what the macro should be defined (typically to 1).
9195 2001-11-12 Akim Demaille <akim@epita.fr>
9197 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9198 From Jim Meyering.
9200 2001-11-12 Akim Demaille <akim@epita.fr>
9202 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9203 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9204 definition used by Automake where LEX is +/- "${missing} lex" and
9205 `missing' itself contains variables.
9207 2001-11-12 Akim Demaille <akim@epita.fr>
9209 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9210 Now that M4sh pushes BODY, the comments were output at the end of
9211 the test suites.
9213 2001-11-08 Akim Demaille <akim@epita.fr>
9215 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9216 that we can trace macros from aclocal.m4.
9217 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9218 obsoleted, and redirect to the former anyway.
9219 Reported by Ralf Corsepius.
9221 2001-11-08 Akim Demaille <akim@epita.fr>
9223 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9224 processed only if present.
9225 * tests/torture.at (Configuring subdirectories): Use autoreconf
9226 instead of successive calls to autoconf.
9227 Add a nonexistent subdirectory to exercise the patch above.
9228 Reported by Ralf Corsepius.
9230 2001-11-08 Kevin Ryde <user42@zip.com.au>
9232 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9233 doesn't accept .S files.
9235 2001-11-07 Akim Demaille <akim@epita.fr>
9237 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9238 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9239 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
9240 * bin/autom4te.in (warn_forbidden): New.
9241 (handle_output): Use it.
9242 Read m4_pattern_forbid with messages.
9244 2001-11-05 Akim Demaille <akim@epita.fr>
9246 * bin/autom4te.in (--normalize): Remove.
9247 * lib/autom4te.in: Adjust.
9249 2001-11-05 Akim Demaille <akim@epita.fr>
9251 * tests/Makefile.am (testsuite): Rename this target as...
9252 ($(TESTSUITE)): this.
9253 From Nicolas Joly.
9255 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9257 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9258 the --prefix option, also remove it's argument.
9260 2001-11-05 Akim Demaille <akim@epita.fr>
9262 * doc/autoconf.texi (testsuite Invocation): Update.
9263 (Writing testsuite.at): Update.
9265 2001-11-03 Akim Demaille <akim@epita.fr>
9267 * doc/autoconf.texi: s/@code/@command/ where appropriate.
9269 2001-11-03 Akim Demaille <akim@epita.fr>
9271 * lib/Autom4te/General.pm: (&catfile, &canonfile)
9272 (&file_name_is_absolute): New, wrappers around routines from
9273 File::Spec.
9274 Use and export them.
9275 (&find_configure_ac): Optionally take a directory where to look at.
9276 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
9277 the arguments.
9278 Default @ARGV to `.', not find_configure_ac.
9279 (&autoreconf): Argument is a directory.
9280 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
9281 * doc/autoconf.texi (autoreconf Invocation): Update.
9283 2001-11-03 Akim Demaille <akim@epita.fr>
9285 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9286 (@export_forward_subs): New.
9287 Add basename, dirname, and fileparse.
9288 (@EXPORT): Adjust.
9289 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9290 Don't look for aclocal flags if we already know aclocal is not
9291 used.
9292 Move aclocal.m4t only if it exists.
9293 Reported by Ezra Peisach.
9295 2001-11-03 Akim Demaille <akim@epita.fr>
9297 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9298 passed on command line, defaulting to ./configure.ac if present.
9299 (&maybe_autoreconf, File::Find): Remove, unused.
9300 (&autoreconf): If autoconf is not used, don't try to trace.
9302 2001-11-02 Akim Demaille <akim@epita.fr>
9304 * configure.ac: Bump to 2.52g.
9306 2001-11-02 Akim Demaille <akim@epita.fr>
9308 Version 2.52f.
9310 2001-11-02 Akim Demaille <akim@epita.fr>
9312 * config/config.guess, config/config.sub, doc/standards.texi:
9313 * config/lispdir.m4: Update from masters.
9314 * configure.ac: Bump to 2.52f.
9316 2001-11-02 Akim Demaille <akim@epita.fr>
9318 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9319 Don't run aclocal when aclocal.m4 is not from aclocal.
9320 From Ezra Peisach.
9321 Don't run libtoolize and gettextize if --install is not given.
9323 2001-11-01 Paul Eggert <eggert@twinsun.com>
9325 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9326 be invoked before _AS_LINENO_PREPARE.
9327 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9328 than character ranges.
9330 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9331 invoking AS_BASENAME. Set the locale variables to 'C' if
9332 possible, as POSIX requires this to get the traditional
9333 behavior.
9334 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9336 2001-10-31 Paul Eggert <eggert@twinsun.com>
9338 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9339 with {}, as that triggers a bug in Bash 2.05.
9341 (_AS_LINENO_PREPARE): Use Sed rather than
9342 Awk. Fix the sed prepass to work even if there are multiple
9343 instances of $LINENO on the same line. Do not substitute for
9344 other variables like $LINENOT. Do not check file dates; such a
9345 check is unreliable on sufficiently fast machines, and removing
9346 the check makes the code simpler and more reliable. Check for
9347 output and chmod failures.
9349 * doc/autoconf.texi (Special Shell Variables): Document
9350 the above.
9352 2001-10-31 Akim Demaille <akim@epita.fr>
9354 * tests/Makefile.am (atconfig): Remove this target, Automake
9355 handles it now.
9357 2001-10-31 Akim Demaille <akim@epita.fr>
9359 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9360 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9361 provided, while it is optional.
9362 * configure.ac: Adjust.
9364 2001-10-26 Paul Eggert <eggert@twinsun.com>
9366 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9367 lib/Autom4te/Struct.pm:
9368 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9369 with 5.005_02.
9371 * doc/autoconf.texi (Special Shell Variables): Document some
9372 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9374 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9375 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9376 eval $LINENO is not portable in practice.
9378 2001-10-24 Akim Demaille <akim@epita.fr>
9380 * lib/Autom4te/General.pm (backname): New.
9382 2001-10-24 Akim Demaille <akim@epita.fr>

9392 2001-10-22 Paul Eggert <eggert@twinsun.com>
9394 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9395 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9396 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9397 POSIX decided to standardize on the int flavor of strerror_r.
9398 Always do char* test, as there's no reason not to.
9399 Assign to a char* var, to catch strerror_r that returns int*.
9401 * doc/autoconf.texi (Particular Functions):
9402 Document the above changes. Also, document the fact that
9403 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9405 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9407 2001-10-20 Akim Demaille <akim@epita.fr>

9410 the executable was missing from the log.

9414 * lib/Autom4te/General.pm (&update_file): If destination is
9415 unchanged, remove the source.

9417 * bin/autoreconf.in: No longer support --m4dir.
9418 (&autoreconf): Display the full path of the configure.ac we are
9419 studying.
9420 Trace it only once.
9421 Be sure to honor --force with gettextize.
9422 Always run aclocal.
9423 * doc/autoconf.texi: Adjust.
9425 2001-10-20 Akim Demaille <akim@epita.fr>
9427 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9428 Remove, dead.
9429 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9430 `intl' is already present, as it refuses unless --force.
9431 (&parse_args): Use -I, --include instead of the old Autoconf
9432 options.
9433 ($localdir, $autoconf_dir): Remove.
9434 (@include): New.
9435 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9437 2001-10-19 Jens Petersen <petersen@redhat.com>
9439 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9451 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9452 comment, explain how to install automatic mode selection.
9453 From Russ Allbery.
9455 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9457 * bin/autoreconf.in (autoreconf): Display the path to the
9458 configure.ac being studied.
9460 2001-10-18 Paul Eggert <eggert@twinsun.com>
9462 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9463 long, to work around a bug in the HP C compiler version HP92453-01
9464 B.11.11.23709.GP.
9466 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9467 (AS_BASENAME_EXPR): New macro.
9468 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9469 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9470 and fall back on 'sed' only if the other two fail. This makes
9471 AS_BASENAME act more like AS_DIRNAME.
9472 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9473 contains white space.
9474 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9475 Use AS_DIRNAME, since I think it's now DOS-friendly.
9476 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9477 Allow "dirname //FOO" to return either / or //, as POSIX allows
9478 either behavior.
9480 2001-10-10 Akim Demaille <akim@epita.fr>
9482 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

9488 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9492 2001-10-10 Akim Demaille <akim@epita.fr>
9494 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

9526 (Syntax of the shell scripts): Don't.
9527 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
9528 bother with $force since...
9529 * lib/Autom4te/General.pm: does.
9531 2001-10-08 Akim Demaille <akim@epita.fr>
9533 * bin/autoreconf.in: Rewrite in Perl.
9534 * configure.ac: Adjust.

9614 CONFIG_SHELL defaults to a shell that supports LINENO if available.
9616 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
9617 shell does not support LINENO, and if CONFIG_SHELL is unset or
9618 empty, and if we can find a shell that does support LINENO,
9619 then set CONFIG_SHELL to that shell and then re-execute
9620 ourselves with CONFIG_SHELL.
9622 2001-10-05 Paul Eggert <eggert@twinsun.com>
9624 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9625 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9626 build of $(TESTSUITE).
9628 2001-10-05 Akim Demaille <akim@epita.fr>
9630 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

9667 compatibility with POSIX shells.

9696 Don't use nested parenthesization. This patch was originally

9705 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9706 Check for `expr' arithmetic overflow, and for compilation failure,
9707 and invoke a new argument $4 if either is discovered.
9708 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9709 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9711 2001-09-28 Akim Demaille <akim@epita.fr>

9737 (Broken/missing compilers, AC_PROG_CPP with warnings)
9738 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
9739 * tests/c.at (Extensions, C keywords)
9740 (Broken/missing compilers, AC_PROG_CPP with warnings)
9741 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
9742 (AC_PROG_CPP requires AC_PROG_CC): here and...
9743 * tests/fortran.at (GNU Fortran 77): there.
9744 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9745 AC_TRY_RUN is about compilation, not shell commands.
9746 (Test Programs): AC_TRY_RUN works as used to be advertised.
9748 2001-09-27 Akim Demaille <akim@epita.fr>
9750 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9751 Raja R Harinath:
9752 Be sure to detect when $LINENO always returns the same value.
9753 Look for the original script, basename($0) is certainly not
9754 enough.
9755 Pass the CLI arguments to `$as_me.lineno'.
9757 2001-09-25 Akim Demaille <akim@epita.fr>
9759 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
9760 Be sure the close and reopen the LOG fd before and after using tee

9852 2001-09-22 Akim Demaille <akim@epita.fr>
9854 Rely on `$LINENO' when possible instead of `__oline__'.
9856 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
9857 `$LINENO' support replacement when not supported.
9858 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
9859 them explicitly to be sure they are not output before this section
9860 (via m4_require). Cosmetic only.
9861 * lib/autoconf/c.m4, lib/autoconf/general.m4,
9862 * lib/autoconf/programs.m4: Replace all the occurrences of
9863 `__oline__' with `$LINENO'.

9871 it works.
9873 2001-09-21 Akim Demaille <akim@epita.fr>
9875 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9876 Suggested by Jim Meyering.
9878 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9893 PATH_SEPARATOR.
9894 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9895 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9896 be used instead of ':'.
9897 * lib/autotest/general.m4: Replace occurrences of ':' in
9898 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9900 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9903 arguments. Fixed a typo.
9905 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9907 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9908 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.

9912 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

9921 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9922 already have $file). Set output files to binary mode (helps avoid
9923 CR issues on DOSish systems).
9925 2001-09-19 Akim Demaille <akim@epita.fr>
9927 * lib/autotest/general.m4: Englishoes.
9928 From Tim Van Holder and Alexey Mahotkin.
9930 2001-09-18 Paul Eggert <eggert@twinsun.com>
9932 * doc/autoconf.texi (Common Shell Constructs): New node,
9933 documenting AS_DIRNAME.
9934 (Limitations of Usual Tools): Refer to it when discussing dirname.
9935 Also, update discussion of POSIX standard to reflect latest draft.
9937 * lib/autoconf/c.m4:
9938 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9940 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9941 Do not pass a first argument with leading '-'
9942 to expr, by parenthesizing initial integers that might be negative.
9944 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9945 now merely checks whether it is an error to pass an argument
9946 to getpgrp.
9948 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9949 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9950 whether it is a (compile-time) error to pass an argument to
9951 getpgrp. This simpler test supports the revised documentation,
9952 and is all that AC_FUNC_GETPGRP's users really need.
9954 2001-09-18 Akim Demaille <akim@epita.fr>
9956 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9958 2001-09-18 Akim Demaille <akim@epita.fr>

9964 2001-09-18 Paul Wagland <paul@wagland.net>
9966 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9967 correctly.
9968 Add test for AS_BASENAME.
9969 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9970 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9971 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9972 * tests/base.at: Fixed the expected responses. The old ones were
9973 one line out...
9974 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9975 the documentation claims it should (and how it behaved in 2.13).
9977 2001-09-18 Akim Demaille <akim@epita.fr>
9979 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9980 the AC_CONFIG_COMMANDS invocation.
9981 This also solves the name clash problems.
9982 Don't set the package's ID.
9983 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9984 No longer to be shipped.
9985 (version.in): Remove.
9986 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9987 * lib/autoconf/status.m4: Adjust.
9988 Use `m4_PACKAGE_STRING'.
9989 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9990 the only optional argument is the name of the test suite.
9991 Expect `package.m4' to define the package signature.
9992 * lib/autom4te.in (Autotest): Add `package.m4?'.
9993 * tests/Makefile.am (package.m4): New.
9994 * tests/suite.at: ifnames is a victim.
9996 2001-09-18 Akim Demaille <akim@epita.fr>
9998 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9999 AC_LIBSOURCE, AC_CONFIG_FILES.
10000 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10001 program version string doesn't match the package's.
10002 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10003 after `(cached)'.
10005 2001-09-17 Paul Eggert <eggert@twinsun.com>
10007 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10008 Allow expression to return any value that can fit into unsigned long
10009 (not int, as before). Check for output errors.
10011 2001-09-17 Bruno Haible <haible@ilog.fr>
10013 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10014 Always include <stdio.h> and <stdlib.h>. Evaluate
10015 the expression in an extra function before these includes. Call
10016 fprintf "%d" only after ensuring the argument is of type 'int'.
10017 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10019 2001-09-17 Paul Eggert <eggert@twinsun.com>
10021 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10022 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10023 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10024 when they don't exist.
10026 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10027 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10028 need it.
10030 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10031 version with the version used by fileutils 4.1, except use
10032 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10033 we don't need it.
10035 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10037 2001-09-13 Akim Demaille <akim@epita.fr>
10039 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10040 _first_.
10041 Reported by Gerrit P. Haase.

10045 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

10073 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
10075 2001-09-13 Akim Demaille <akim@epita.fr>
10077 * lib/autotest/general.m4 (AT_INIT): Create and remove
10078 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10079 test suites can cohabit.
10081 2001-09-13 Akim Demaille <akim@epita.fr>
10083 * tests/mktests.sh: Don't output banners for empty test files.
10085 2001-09-13 Akim Demaille <akim@epita.fr>
10087 Test suites can be run independently of configure.

10102 (Syntax of the shell scripts): Don't check ifnames.
10103 (AT_CHECK_PERL_SYNTAX): New.

10151 2001-09-07 Akim Demaille <akim@epita.fr>
10153 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
10154 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
10155 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
10156 related variables into `at_package_*'.

10168 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,

10182 to avoid GCC warnings.
10183 From Uwe Seimet.
10185 2001-09-05 Akim Demaille <akim@epita.fr>
10187 * bin/autom4te.in: --language is -l, not -s.
10189 2001-09-05 Akim Demaille <akim@epita.fr>
10191 Be ready to handle filenames as stupid as `dnl.at', for if even
10192 the maintainer is dumb enough to do that...
10194 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10195 excellence in M4 quotation: consider `__file__' is active.

10228 New, extracted from main.
10229 Use IO::File wherever possible.

10232 Don't invoke `_au_disable', since ac was not loaded, but just

10235 2001-08-31 Akim Demaille <akim@epita.fr>

10260 2001-08-31 Akim Demaille <akim@epita.fr>
10262 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10263 (testsuite Scripts): There is no such thing as `atconfig.in'.
10264 And actually one diagram is missing: test suite runtime.
10266 2001-08-31 Akim Demaille <akim@epita.fr>
10268 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10269 inverse order.
10271 2001-08-31 Akim Demaille <akim@epita.fr>
10273 * bin/autoupdate.in (@include): `installcheck' revealed the path
10274 to m4sugar was lacking!
10276 2001-08-31 Akim Demaille <akim@epita.fr>
10278 * man/Makefile.am (.x.1): We really have to pass
10279 autom4te_perllibdir.
10281 2001-08-31 Akim Demaille <akim@epita.fr>
10283 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
10284 debug scripts, in particular passing explicitly listed tests to
10285 run is stupid.
10287 2001-08-31 Akim Demaille <akim@epita.fr>
10289 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10290 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10291 Use directly autom4te, not autoconf.
10292 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
10294 2001-08-31 Akim Demaille <akim@epita.fr>
10296 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
10297 * bin/autoheader.in (%symbol): Strip arguments of macros.
10299 2001-08-31 Akim Demaille <akim@epita.fr>
10301 * doc/autoconf.texi: Catch up -I, --include changes.
10303 2001-08-31 Akim Demaille <akim@epita.fr>
10305 * bin/autom4te.in (&parse_args): Die on unknown languages.
10306 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
10307 need for autoconf.
10308 Promote --include over --macrodir and other obsolete options.
10310 2001-08-31 Akim Demaille <akim@epita.fr>
10312 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
10313 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
10314 * bin/autom4te.in ($autoconf): Pass --force.
10315 `print $out' doesn't print `$_' but `$out'.
10316 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10317 (autoheader): Pass --force since the test suite goes too fast for
10318 the time stamps.
10319 Adjust to the new autoheader messages.
10321 2001-08-31 Akim Demaille <akim@epita.fr>
10323 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
10324 Check the completeness of the #template.
10325 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
10326 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
10327 invocation.
10329 2001-08-31 Akim Demaille <akim@epita.fr>
10331 * lib/Autom4te/General.pm (&find_file, &update_file): New.
10332 * bin/autoupdate.in, bin/autoheader.in: Adjust.
10333 Drop AC_MACRODIR dead for real.
10334 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10335 `autoheader: `config.hin' is created'.
10336 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10338 2001-08-31 Akim Demaille <akim@epita.fr>
10340 * bin/autoheader.in: Rewrite in Perl.
10341 * tests/autoheader: Adjust.
10343 2001-08-31 Akim Demaille <akim@epita.fr>
10345 * bin/autoconf.in (--include, -I): New option.
10346 Map --localdir, --autoconf-dir onto it.
10347 Forward autom4te's options instead of interpreting them.
10348 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10349 There is no such envvar since the inception of autom4te.cfg.
10350 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10351 * bin/autoupdate.in: Adjust, and perform more control.
10352 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
10353 * tests/autoconf: Dittowise.
10355 2001-08-31 Akim Demaille <akim@epita.fr>
10357 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10358 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10359 optionally `FILE'.
10360 Use -e, not -f, since /dev/null for instance is OK.
10361 (&parse_args): Adjust.
10362 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10364 2001-08-31 Akim Demaille <akim@epita.fr>
10366 * configure.ac: Also find tested executables in bin.
10367 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10368 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10369 installed peer executables, only PATH is allowed to resolve it.
10370 Pass `autoconf_dir' via options, not via invisible envvars.
10371 * lib/Autom4te/General.pm (&find_peer): Remove.
10372 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10373 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10374 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10375 find the executables for it.
10376 * tests/Makefile.am: Major cleanup. Too lazy to document...
10377 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10378 We only need PERL.
10379 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10380 indeed related to running the test suite, while passing
10381 --autoconf-dir and others is related to running non installed
10382 Autoconf executables. So don't do that, leave it to...
10383 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10384 * tests/autoscan: New.
10385 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10386 refer to library files: rely on --language.
10388 2001-08-29 Akim Demaille <akim@epita.fr>
10390 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
10391 s/--set/--language/.
10393 2001-08-29 Akim Demaille <akim@epita.fr>
10395 * doc/autoconf.texi: Strip the @nodes.
10396 Suggested by Paul Eggert.
10397 (Initializing configure): Typo.
10399 2001-08-29 Akim Demaille <akim@epita.fr>
10401 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10402 Suggested by Paul Eggert.
10404 2001-08-29 Akim Demaille <akim@epita.fr>
10406 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10407 download in a tmp dir.
10409 2001-08-29 Akim Demaille <akim@epita.fr>
10411 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10412 case insensitive OSes out there :(
10413 From Tim Van Holder.
10415 2001-08-29 Akim Demaille <akim@epita.fr>
10417 * lib/autom4te.in: New.
10418 * lib/Makefile.am (edit, autom4te.cfg): New.
10419 * bin/autom4te.in (BEGIN): Simplify.
10420 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
10421 (&load_configuration): New. Use it.
10422 (&parse_args): Support --mode, --set, and --melt.
10423 * bin/autoconf.in: Simplify and adjust.
10424 * tests/Makefile.am (AUTOMAKE): Use --set.
10425 * tests/atlocal.in: Adjust.
10426 * BUGS: distcheck and check are weak.
10428 2001-08-29 Akim Demaille <akim@epita.fr>
10430 * lib/autotest/general.m4: Use
10431 foo=`(command) 2>/dev/null`
10432 not
10433 foo=`command` 2>/dev/null
10434 (at-devnull): Rename as...
10435 (AT-devnull): this.
10436 (--clean): Remove AT-* files too.
10437 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10438 Reported by Nicolas Joly.
10440 2001-08-28 Akim Demaille <akim@epita.fr>
10442 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
10443 quotes inside single quotes.
10444 Reported by Nicolas Joly.
10446 2001-08-28 Kevin Ryde <user42@zip.com.au>
10448 * doc/autoconf.texi (Function Portability): Mention C right shifts.
10450 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
10452 * lib/autotest/general.m4: Reword some messages.
10453 (AT_INIT): Check for the `times' builtin before using it.
10454 Support test ranges as arguments to the testsuite.
10455 Have -e imply -d as the help text suggested.
10457 2001-08-27 Akim Demaille <akim@epita.fr>
10459 * Makefile.maint: Formatting changes.
10460 (do-po-update, po-update, cvs-update, update): New targets.
10461 (AMTAR): Remove.
10463 2001-08-27 Akim Demaille <akim@epita.fr>
10465 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

10468 <AUTOTEST_PATH>: May contain absolute dir names.
10470 2001-08-27 Akim Demaille <akim@epita.fr>
10472 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10473 Support `VAR=VAL' as arguments.
10474 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
10475 may be set via the command line.
10477 2001-08-27 Akim Demaille <akim@epita.fr>
10479 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
10480 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
10481 first the build dirs, then the src dirs.
10482 * configure.ac (AC_CONFIG_TESTDIR): Adjust.
10484 2001-08-27 Akim Demaille <akim@epita.fr>
10486 * lib/autotest/general.m4 (AT_INIT): Output the definition of
10487 at_data_files earlier.
10488 (--clean, -c): New option.
10489 * tests/Makefile.am: Use this option.
10491 2001-08-27 Akim Demaille <akim@epita.fr>
10493 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
10494 `ac_top_builddir' to mimic Automake's vocabulary, which much more
10495 readable.
10496 Adjust callers.
10497 * doc/autoconf.texi (Configuration Actions): Document the vars
10498 available in commands.
10499 Emphasize the risks of collisions in init-cmds.

10503 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
10504 (Initializing configure): this new node.
10506 2001-08-27 Akim Demaille <akim@epita.fr>
10508 * Makefile.am (EXTRA_DIST): INSTALL.txt is a dead hack.

10519 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
10520 to...
10521 * lib/autoconf/autoheader.m4: this new file.
10522 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)
10523 (_AH_VERBATIM_OLD, AH_TEMPLATE, _AH_TEMPLATE_OLD, AH_TOP, AH_BOTTOM):
10524 Move to...

10527 2001-08-27 Akim Demaille <akim@epita.fr>
10529 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
10530 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
10531 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
10532 -> ac_dir).
10533 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
10534 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
10536 2001-08-27 Akim Demaille <akim@epita.fr>
10538 * lib/autoconf/autoconf.m4 (AC_CONFIG_COMMANDS)

10561 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
10562 (AMTAR): Help automake define it.
10563 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
10564 needed, 1.5 can have a macro and a target with the same name.
10565 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
10566 * m4/strip.m4: New.

10579 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
10580 Adjust callers.
10581 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10582 the name of the directory they're in, instead of the filename,
10583 since version.m4 is now in m4sugar, but m4_acversion must not be
10584 classified as an Autoconf macro.
10585 ($input_m4): Don't qualify the path to m4sugar.
10586 Rather, pass autoconf_dir to m4.
10587 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
10588 * tests/suite.at: Require 2.52c.
10590 2001-08-27 Akim Demaille <akim@epita.fr>

10602 of config.log on traps.
10603 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
10604 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
10605 for config.status'.
10606 Open the log as soon as possible.
10607 Use the same log introduction as configure's.
10609 2001-08-22 Paul Eggert <eggert@twinsun.com>
10611 * doc/autoconf.texi (Indices): New node.
10612 Move indices out of the top level menu and into this submenu.
10614 2001-08-22 Akim Demaille <akim@epita.fr>
10616 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10617 AC_TRY_COMMAND.
10618 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
10620 2001-08-22 Akim Demaille <akim@epita.fr>

10659 * configure.ac (AT_CONFIG): Fix the path.
10660 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
10661 can be used.
10663 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
10665 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
10666 program with AC_LANG_PROGRAM before feeding it to
10667 AC_COMPILE_IFELSE. Cleanup grep usage.
10669 2001-08-20 Akim Demaille <akim@epita.fr>
10671 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
10672 * NEWS, README, README-alpha, TODO, tests/README: This package is
10673 `Autoconf', not `autoconf' (the executable).
10675 2001-08-20 Akim Demaille <akim@epita.fr>
10677 Info readers seem to need `Index' in the index node title :(
10679 * doc/autoconf.texi: Reverse the 2001-08-15 change which
10680 simplified index node names.
10682 2001-08-20 Akim Demaille <akim@epita.fr>
10684 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
10685 arguments are not literals.
10686 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
10687 Specify the output variables, and macros defined.
10689 2001-08-20 Akim Demaille <akim@epita.fr>
10691 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
10692 (Examining Syntax) <AC_TRY_COMPILE>

10793 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

10811 * doc/autoconf.texi: Work around Texinfo buglets.
10812 (Transformation Rules): One example is enough, users are expected
10813 to have their brains on. And BTW, use DESTDIR.
10814 (dvar): New macro. Use it.
10816 2001-08-17 Akim Demaille <akim@epita.fr>
10818 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

10866 (cvs-dist): depends upon it.
10868 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
10870 * tests/Makefile.am: Use a clean-local rule to remove
10871 autom4te.cache (it's a directory, not a file.
10872 * Makefile.am: Ditto (but maintainer-clean-local).
10874 2001-08-15 Akim Demaille <akim@epita.fr>
10876 * bin/autom4te.in (@m4_warning): New.
10877 (&handle_m4): Use it.
10878 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10879 warnings are issued at each run.
10880 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10881 is in the src tree.
10883 2001-08-15 Akim Demaille <akim@epita.fr>
10885 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
10886 don't waste time running `autoupdate --version' works.
10887 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10889 2001-08-13 Akim Demaille <akim@epita.fr>
10891 * doc/autoconf.texi (ma): Rename this index as...

10948 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10950 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10951 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10952 * doc/autoconf.texi (C Compiler Characteristics): Update
10953 documentation for AC_C_BIGENDIAN.
10955 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10957 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10958 magic values from an object file when cross-compiling.
10959 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10961 2001-08-10 Akim Demaille <akim@epita.fr>
10963 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10964 effects.
10965 Suggested by Russ Allbery.
10967 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10969 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10970 current $prefix to the sub-configures.
10972 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10974 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10975 extension (needed on BeOS). Reported by Guido van Rossum.
10977 2001-08-09 Akim Demaille <akim@epita.fr>
10979 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10981 2001-08-07 Akim Demaille <akim@epita.fr>
10983 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10984 removed.
10985 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10986 No need to remove the files before and after the each test, before
10987 each test and at the end of the suite is enough.
10988 Display only the children `times', not the shell's.
10989 If the test failed or was skipped, at-times is not available.
10991 2001-08-07 Akim Demaille <akim@epita.fr>
10993 Always produce testsuite.log, including when there are no
10994 failures. This helps getting information on skipped tests, and
10995 duration of the tests. Err, implement the latter btw.
10997 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10998 Dump information on the first run of each test.
10999 (AT_CLEANUP): Create `at-times' containing the duration of the
11000 test group.
11002 2001-08-07 Akim Demaille <akim@epita.fr>
11004 The use of `dumpstat' revealed that `len' was used although it
11005 should not. m4_text_wrap was using it, but in the Autoconf world
11006 where it is legal. Hence (i) test M4sh in its own world, not
11007 Autoconf's, and (ii), ahem, fix the bug :)
11009 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11010 does not like `' instead of [].
11011 (AT_INIT): Forbid `^_?AT_'.
11012 And don't output such tokens.
11013 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11014 `script.as', and `autom4te.cache'.
11015 Remove `empty' and `macro' which are no longer used.
11016 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11017 * tests/m4sugar.at: Use it.
11018 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11020 2001-08-07 Akim Demaille <akim@epita.fr>
11022 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11024 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11026 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11028 2001-08-04 Akim Demaille <akim@epita.fr>
11030 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11031 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11032 AC_TRY_LINK.
11033 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11034 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11035 (AC_F77_MAIN): Likewise.
11037 2001-08-04 Akim Demaille <akim@epita.fr>
11039 Don't rely on M4sugar outputting the patterns in files, since we
11040 might process the output _without_ running m4, hence without these
11041 files.
11043 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11044 * bin/autom4te.in (@Request::includes): Remove, unused.
11045 (@Request::source): Rename as...
11046 (@Request::input): this.
11047 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11048 (&handle_output): Fetch the patterns from the traces.
11049 `$forbidden' and `$allowed' are constant: use m//o.
11050 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11051 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11053 2001-08-04 Akim Demaille <akim@epita.fr>
11055 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11056 autoconf', i.e., in addition to caching traces, cache the output.
11058 * bin/autom4te.in (Request::cache): Rename as...
11059 (Request::id): this.
11060 ($cache, $icache, $tcache, $ocache): New.
11061 (&handle_m4): Save M4 output in the cache instead of $tmp.
11062 (&handle_output): Adjust.
11063 (&up_to_date_p): Check that the output cache is up to date too.
11064 (top level): Run `&handle_m4' iff force or the cache is invalid.
11065 Run `&handle_output' if the output cache is more recent.
11067 2001-08-04 Akim Demaille <akim@epita.fr>
11069 * bin/autom4te.in ($force): New.
11070 (&parse_args, &print_usage): -f, --force is a new option.
11071 (&handle_output): CPP directives might have spaces after `#'.
11072 (&parse_args): The first file only can be frozen.
11074 2001-08-04 Akim Demaille <akim@epita.fr>
11076 Don't let autom4te compute the `include' traces several times:
11077 first check that the trace cache file is up to date, and then
11078 compare its timestamp with that of the output.
11080 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11081 the preamble. Don't require 5.005 as Autom4te::General does it,
11082 and better yet (use `use', not `require'!).
11083 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11084 Class::Struct as Autom4te::Struct.
11085 * lib/Autom4te/General.pm (File::stat): Use it.
11086 (&mtime): New, export it.
11087 * bin/autom4te.in: Use it.
11088 Declare `$req' is invalid if it is outdated.
11089 Don't declare it valid before saving it if something went wrong.
11091 2001-08-04 Akim Demaille <akim@epita.fr>
11093 Autom4te shall not encode Autoconf data, and preselecting traces
11094 must be proposed to the users.
11096 * bin/autom4te.in (@required_trace): Remove.
11097 (@preselect): New.
11098 (&parse_args, &print_usage): -p, --preselect is a new option.
11099 (&up_to_date_p): Adjust.
11100 * bin/autoconf.in: Preselect some Autoconf macros.
11102 2001-08-04 Akim Demaille <akim@epita.fr>
11104 * tests/tools.at (autoconf --trace: user macros): Check traces on
11105 macros invoked without arguments, and macros invoked with multiple
11106 lines arguments.
11108 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11110 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11111 arguments.
11113 2001-08-03 Akim Demaille <akim@epita.fr>
11115 * bin/autoconf.in ($@): Work around the usual sh bug.
11116 From Nicolas Joly.
11118 2001-08-03 Akim Demaille <akim@epita.fr>
11120 Clean up the handling of the M4 builtins tracing exception.
11122 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11123 trace requests.

11127 (&parse_args): Complete the trace requests with alternate names.
11128 (&handle_traces): Hence no longer do it here.
11129 (&trace_requests): Remove, unused.
11131 2001-08-03 Akim Demaille <akim@epita.fr>
11133 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11134 m4_if, and m4_wrap.
11136 2001-08-03 Akim Demaille <akim@epita.fr>
11138 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11139 (m4_divert_pop): Dump the whole diversion stack when a diversion
11140 mismatch happens.
11141 * bin/autom4te.in (&handle_output): Remember of the first
11142 occurrence of a possibly undefined macro, not the last.
11143 Complain about the possibly undefined macros in the same order as
11144 the appear in the output.
11145 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11146 * tests/tools.at (autoconf: forbidden tokens, basic)
11147 (autoconf: forbidden tokens, exceptions): No longer sort
11148 autoconf's stderr, as it is now deterministic.
11149 Check that `dnl' is caught.
11151 2001-08-01 Akim Demaille <akim@epita.fr>
11153 * configure.ac: Bump to 2.52c.
11155 2001-08-01 Akim Demaille <akim@epita.fr>

11565 compiler, not the preprocessor.
11566 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

11568 the right thing.
11569 * Makefile.am (.m4.m4f): Emphasize M4 error messages and fail
11570 earlier if there are.
11572 2001-07-03 Akim Demaille <akim@epita.fr>
11574 * autoscan.in ($initfile): Remove.
11575 (&find_file): Rename as...

11601 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
11602 dummy alternate main is required even if the user provides her own
11603 'main'.
11604 (AC_F77_MAIN): New macro to detect whether it is possible to
11605 provide an alternate 'main' function name, using the 'main' from
11606 the Fortran libraries.
11607 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
11608 cross-language link tests can be performed successfully.
11609 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
11610 after $LIBS, for consistency; this should be the general rule since
11611 the user may want to link to Fortran libraries that require $FLIBS.
11612 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
11614 2001-06-29 Pavel Roskin <proski@gnu.org>
11616 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
