24 for the default, which the user can override.
25 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
27 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
28 didn't work if some values were cached but not others. Test for
29 broken lex libraries like native ia64-hp-hpux11.22; see
30 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
31 work around the problem by preferring an empty LEXLIB to -lfl or
32 -ll. Let the user set LEXLIB='' to indicate no library needed.
34 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
36 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

154 longer supported by Sun.
156 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
158 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
159 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
160 -Wundef -Werror". Problem reported by David Fang in
161 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

228 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
229 compiler complains about it, even if things works after the
230 complaint. Problem reported by Peter O'Gorman.
232 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
233 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
234 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
236 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
238 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
239 after -R regardless of host. Patrick Welche reports that this
240 fixes things on NetBSD 3.99.
242 * NEWS: Recommend M4 1.4.5.
244 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
245 * tests/tools.at (autom4te cache): Update wording of diagnostic

260 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
262 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
263 more globally, since the 2006-06-30 patch didn't suffice. Problem
264 reported by Keith Marshall. Also, don't bother with builddir2,
265 since it shouldn't be needed any more.
267 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
269 * doc/autoconf.texi (Generic compiler characteristics):
270 Document AC_COMPUTE_INT. Fix wrong statements on Default

288 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
289 Require that long long int be at least 64 bits wide. C99 requires
290 this and enough programs depend on it so we should check for it.
291 Bruno Haible reports in
292 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
293 that long long int is 32 bits wide with some nonstandard compilers.

299 to a nonexistent file, so that we don't have to worry about
300 a local site configuration that doesn't use /usr/local.
301 Problem reported by Keith Marshall in
302 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
304 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
306 * doc/autoconf.texi: Be more consistent about using @acronym with
307 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
308 quite right (it talked about "OSF/Tru64", even though the
309 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
310 and it even mentioned "OSF 4"!) and at this point there's little
311 reason to talk about OSF any more, since it died in 1994.
312 (Specific Compiler Characteristics): Simplify example of
314 (File Descriptors): Reorder to make the text flow better.
315 Remove joke about "appreciate the various levels"; I didn't get it.
316 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
317 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
318 (File Descriptors, Limitations of Usual Tools):
319 Tone down the advice against renaming or removing open files.

322 2006-06-26 Stepan Kasal <kasal@ucw.cz>
324 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
325 -lXt in LIBS, idea from Karsten Hopp; this was due since
328 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
329 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
330 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
331 (which belong to Xt, not X itself). See Debian bug 327655.
333 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
335 * configure.ac (AC_INIT): Bump to 2.60a.

349 quadrigraph correctly in traces.
351 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
354 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
355 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
357 * doc/autoconf.texi (Changed Directory Variables): New node,
358 to document the whole `datarootdir' business a bit better.
360 * tests/torture.at (datarootdir workaround): Extend test.
361 Prompted by report by Alexandre Julliard.
363 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
365 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
366 when using default mode of IBM C 6 for AIX. Problem and two-line
367 fix reported by Larry Jones.
369 2006-06-22 Alexandre Julliard <julliard@winehq.org>
371 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
372 about literal '${datarootdir}' if a definition is found in the
375 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
377 * NEWS: Use "M4" rather than "m4" when appropriate.
378 Problem reported by Eric Blake.
379 * doc/autoconf.texi: Likewise.
380 Use @acronym around BSD, GCC, and GNU when appropriate.
381 (Why GNU M4): Renamed from "Why GNU m4".
382 (Redefined M4 Macros): Mention that Posix
383 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
384 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
387 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
389 * bin/autom4te.in (handle_output): Do not forbid the empty
391 * tests/tools.at (autoconf: the empty token): New test.
393 2006-06-20 Stepan Kasal <kasal@ucw.cz>
395 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
396 calls, so that we do not care whether they are LIFO or FIFO;
397 in the m4_wrap, do not check which diversion is the topmost
398 one, just check that the stack is balanced at the end.
399 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
400 base diversion forever--pop the previous diversion before
401 opening the new one; consequently, remove the m4_wrap call.
402 * lib/autotest/general.m4 (AT_INIT): Likewise.
403 * tests/m4sugar.at: Do not use
404 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
406 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
407 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
409 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
410 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
411 Rework example of m4wrap token-pasting trouble so that it doesn't
412 care whether it's LIFO or FIFO.
413 Fix some "contrary to"s that are awkward in English.
415 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
417 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
418 to `yes' instead of `int$1_t' if the type is found, for more
419 consistent configure output (where $1 is the number of bits).
420 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
421 Suggested by Bruno Haible.
423 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
424 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
425 with system headers. Report by Bruno Haible.
427 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
429 * config/config.guess, config/config.sub: Sync from upstream.
431 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
432 in order to avoid picking up an older installed frozen m4sh.m4f.
433 Besides an outdated shell startup, this could have been created
434 by an earlier M4 version with incompatible frozen file format.
436 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
438 * README: Recommend m4 1.4.4 instead of 1.4.3..

444 (Making testsuite Scripts, Defining Directories):
445 Quote variable usages better.
446 (Making testsuite Scripts): Add clean-local rule to makefile
447 snippet, by Eric Blake.
448 (Installation Directory Variables): Fix table item font.
449 Reword slightly to clarify. Generalize advice about
450 not using special characters to include all file-related
451 vars, not just VPATH.
452 (Special Chars in Variables): Warn about special characters in
454 (Assignments): Clarify default-value example as suggested by
456 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
457 (Special Shell Variables): Note leading ./ or ../, as suggested
459 (Limitations of Builtins): Under cd, warn about CDPATH.
460 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
463 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
465 * doc/autoconf.texi (Configuration Actions): Remove duplicate
466 `@var', for texi2html.
467 (Systemology): Some more word wrapping, for DVI output.
468 (autom4te Invocation): The short option for `--melt' is `-M',
471 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
473 * doc/autoconf.texi: More formatting and English tweaks,
474 many suggested by Ralf Wildenhues.
475 Reword to avoid "@code{...}'s" and the like, since it's ugly
476 with Emacs info mode. discontents -> woes.
477 Put a few "will"s back. time stamp -> timestamp.
478 side-effect -> side effect.
480 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
482 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
483 Warn about $@ not persisting. Problem reported by Julien Danjou in
484 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
485 (Special Chars in Names): Renamed from Leading _ in Macro Names.
486 Mention other special chars, too.
488 2006-06-14 Eric Blake <ebb9@byu.net>
490 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
492 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
494 * doc/autoconf.texi: Some systematic minor improvements, as
495 follows. Use "makefile" when talking about makefiles
496 generally (which might be named "makefile" or "Makefile" or even
497 "foo.mk"), "Makefile" when talking about a specific makefile
498 called "Makefile". This unclutters the text from weird quotes
499 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
500 values" rather than "@var{foo}s" and similar constructs containing
501 "}s". Use "Make rules" rather than "Makefile rules". Minor
502 English-language improvements. Change the prefix "sub-" to "sub"
504 Put blank lines around examples more consistently.
505 Avoid "rather" and "very" as intensifiers.
506 Avoid "will" as an auxiliary.
507 (Limitations of Make): Split this node into....
508 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
509 (Leading _ in Macro Names, Backslash-Newline-Newline):
510 (Backslash-Newline Comments, Long Lines in Makefiles):
511 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
512 (obj/ and Make, make -k Status, VPATH and Make):
513 (VPATH and Double-colon, $< in Explicit Rules):
514 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
515 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
516 New nodes, resulting from splitup of Limitations of Make.
517 All cross-references changed. Raise the top node from
518 a section to a chapter, and all subnodes accordingly.
519 Redo the introductory wording to match the new organization.
520 (Installation Directory Variables): Use an example that is
521 closer to what Autoconf actually does. Mention that VPATH's
522 value should not contain metacharacters or white space.
523 (Fortran Compiler): Fix a VPATH bug in an example.
524 (Leading _ in Macro Names): Mention that this problem is no longer
525 of practical concern.
526 (VPATH and Make): Reword the advice to make it clearer
527 that Autoconf and Automake support VPATH in non-GNU make, but
528 many packages have bugs in this area.
529 ($< in Explicit Rules): Refer to Build Directories rather
530 than using a (non-VPATH-safe) example.
531 (Automatic Rule Rewriting): Mention the sort of disaster that
532 can ensue with Solaris-style rule rewriting with VPATH.
534 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
536 * doc/install.texi (Compilers and Options): Weaken the
537 suggestion to use GNU make for VPATH builds.

540 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
542 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
543 in regular expression.
545 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
547 * doc/autoconf.texi (Installation Directory Variables):
548 Drop extra @samp from `@table @samp' item.
549 (Limitations of Usual Tools): Comment fix.
550 Do not nest @samp just to point to other table items.
551 (Writing testsuite.at) <AT_CHECK>: The second argument to
552 `@dvar' is already @samp'ed.
553 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
554 do not use @var in the second argument.
556 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
558 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
559 $as_shell.exe too. Problem reported by Andreas Buening in
560 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
562 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
564 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
565 `unused variable' compiler warning, for `-Wall -Werror'.
566 Reported by Jaap Haitsma in
567 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
569 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
571 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
572 case the compiler dumps core. Problem reported for
573 OpenServer 5.0.7 by Tim Rice in
574 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
575 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
578 2006-06-06 Tim Rice <tim@multitalents.net>.

590 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
592 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
593 typically overflows on x86 CPUs, even though the C standard
596 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
598 * configure.ac (AC_INIT): Bump to 2.59e.
601 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
605 * config/texinfo.tex: Sync from upstream.
607 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
608 seen, invoke libtoolize with `--ltdl' argument.
609 * lib/autom4te.in (Autoreconf-preselections): Adjust.
611 Suggested by Eric Blake.
613 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
615 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
616 reported by Ralf Wildenhues.
617 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
619 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
623 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

629 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
630 message issued by AC_REQUIRE.
631 * tests/m4sugar.at: Check m4_require's error message.
632 * tests/base.at: Check AC_REQUIRE's error message.
633 * tests/local.at (AT_CHECK_M4): New macro, almost identical
635 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
637 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
638 `expout' as the last parameter.
639 * tests/tools.at: Adapt to the above change.
641 2006-06-04 Stepan Kasal <kasal@ucw.cz>
643 * doc/autoconf.texi (Limitations of Usual Tools): Correct
644 information about race-free implementations of mkdir.
646 2006-06-04 Eric Blake <ebb9@byu.net>
648 * bin/autoreconf.in (help): Document M4 environment variable.
649 * bin/autoconf.as (Usage): Likewise.
650 * bin/autom4te.in (help): Likewise.
651 * doc/autoconf.texi (autom4te Invocation): Likewise.
653 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
655 * NEWS: GNU make now recommended for VPATH builds.
656 Mention that some macros are now documented to be obsolescent.
658 Prefer "current" to "modern" to describe
659 currently-used (albeit perhaps old-fashioned) hosts.
660 Mention which ancient features no longer need to be worried about.
661 setgid -> set-group-ID
662 setuid -> set-user-ID (these are the Posix terms)
663 Fix some misuses of "only".
664 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
665 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
666 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
667 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

671 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
672 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
673 Mention that these macros are obsolescent.
674 (Installation Directory Variables): shall -> should
675 (File Descriptors): Mention that 0, 1, 2 might get reopened.
676 Mention that it's now safe to use 3 and 4.
677 (Limitations of Usual Tools): cp -r is now specified by Posix.
678 Omit longwinded and obsolescent discussion of cp -f.
679 Modernize discussion of expr, ls.
680 (Limitations of Make): Modernize discussion of VPATH builds.
681 Mention $? as a workaround in some cases.
682 * doc/install.texi (Basic Installation):
683 Mention "./configure; make; make install" first. Be more
684 specific about why this file is generic. Remove unnecessary
685 parens. Remove misleading "only". Remove obsolete advice
686 about csh. Don't say "configure" takes awhile; say it
687 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
688 and CC=c99 rather than CC=c89, as these are blessed by current
689 Posix. Recommend GNU make if doing a VPATH build.
691 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
693 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
694 examples involving shell prompts.
696 2006-06-02 Stepan Kasal <kasal@ucw.cz>
697 and Paul Eggert <eggert@cs.ucla.edu>
699 * doc/autoconf.texi (Here-Documents): Add details about the
700 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
701 use "here-documents" instead of "here documents".
703 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
705 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
707 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
709 * doc/autoconf.texi (File System Conventions): Warn about ":"
710 anywhere in directory names.
712 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
714 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
715 about quoting the case statement, just in case.
716 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
717 was fixed in ksh93g; reported by Ralf Wildenhues.
719 2006-05-31 Stepan Kasal <kasal@ucw.cz>
721 * doc/autoconf.texi (System Services): Do not document
722 overriding EXEEXT via ac_cv_exeext=ext.
723 (Particular Programs) <AC_PROG_MKDIR_P>:
724 Document that ${MKDIR_P} understands --.

731 argument with leading hyphen. Problem reported by Paul Eggert.
733 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
735 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
736 about quoting ac_try: quote all of it, if any of it seems suspicious.
737 This means we don't have to worry about ${ or sed any more.
738 Also, double-quote the case statement, to work around misuses via
739 underquoting as reported by Ralf Wildenhues in
740 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
741 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
742 undocumented and dangerous macro.
743 Problem reported by Ralf Wildenhues in
744 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
746 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
748 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
749 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
750 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
752 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
754 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
755 since evidently some packages rely on the old, broken behavior.
756 Problem reported by Ralf Wildenhues in
757 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
758 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
759 pre-2006-05-26 definitions, but leave in the comments that
760 these macros are dangerous and should not be used.
761 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
762 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
763 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
764 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
765 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
767 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
769 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
770 the use of 'tr', since this is our only use of 'tr'.
772 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
773 and Paul Eggert <eggert@cs.ucla.edu>
775 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
776 Don't assume 'grep' works on long lines, since AIX grep doesn't.
778 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
780 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
781 the output file in the `${datarootdir}' test.
783 2005-05-28 Stepan Kasal <kasal@ucw.cz>
784 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
786 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
787 mention of `datarootdir' in the input file(s), but literal
788 `${datarootdir}' in the output file, and we haven't warned yet,
789 then warn as well: the user may have (erroneously) used
790 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
791 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
792 * tests/torture.at (datarootdir workaround): Extend this test.
795 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
796 and Paul Eggert <eggert@cs.ucla.edu>
798 * doc/autoconf.texi (autoheader Invocation): The first argument to
799 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
800 alternatives and clear up the language a bit.
802 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
804 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
805 ac_config_guess, ac_config_sub, ac_configure.
806 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
807 Fix typo that prevented an unnecessary space from being removed.
808 Problems reported by Ralf Wildenhues in:
809 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
811 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
813 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
814 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
815 Don't use the term "thread-safe" to talk about mkdir race
816 conditions, since the problem is more a process than a thread
817 issue. Problem reported by Stepan Kasal in:
818 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
819 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
820 the test for 'install' more closely. Look at MKDIR_P first.
821 Look in the PATH, and at /opt/sfw/bin.
822 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
823 Don't bother to try mkdir -p, since we already check mkdir --version;
824 just look at the version number. (There's no easy way to check
825 for race-free implementations.)
826 * tests/tools.at (autoconf: subdirectories): Adjust to above
827 changes, since MKDIR_P now might end in "/mkdir -p".
829 * doc/autoconf.texi (autoheader Invocation): Mention that the
830 first arg of AC_DEFINE_UNQUOTED must be a literal.
831 Problem reported by Ben Pfaff in
832 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
834 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
835 * doc/autoconf.texi (Special Chars in Variables): New section.
836 (Preset Output Variables): Warn about special chars in CPPFLAGS.
837 (Installation Directory Variables): Quote $(datadir) better.
838 (Limitations of Builtins): Describe some of eval's trickiness.
840 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
841 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
842 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
843 in front of every arg, not just trailing args. Quote apostrophes.
844 (_AC_EVAL_ECHO): New macro.
845 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
846 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
848 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
849 exposed by quoting of eval argument. Put the command on line line
851 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
852 (_AC_PATH_X, AC_PATH_X): Quote more safely.
853 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
854 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
855 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
856 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
857 Use eval more safely.
858 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
859 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
861 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
862 lines, exposed by quoting of eval argument.
864 2006-05-26 Stepan Kasal <kasal@ucw.cz>
865 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
867 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
868 initialization of `ac_cv_exeext', do not override it if it was
869 already set, unless it was set to `no', for compatibility with
870 Autoconf-2.13, and comment this.
871 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
872 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
873 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
874 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
875 Document that this test may be overridden by setting
878 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
880 Revert these two patches:
882 2006-04-06 Eric Blake <ebb9@byu.net>
883 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
884 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
887 2006-04-01 Stepan Kasal <kasal@ucw.cz>
888 Clean up _AC_COMPILER_EXEEXT* macros.
889 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
890 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
891 ac_file to the name of the default output file and call
892 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
893 initial `rm' of the candidate files...
894 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
895 the same list in subsequent `rm' calls, and for the temporary
896 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
897 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
898 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
899 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
900 no longer needed) by libtool. Make it a cache check.
901 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
902 copied here by mistake.
903 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
905 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
906 _AC_COMPILER_OBJEXT directly.
907 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
909 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
911 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
912 Fix description of how the buggy `sed' works.
914 2006-05-25 Noah Misch <noah@cs.caltech.edu>
918 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
919 ENOLCK. Only mention `make -j' when applicable. Only raise
920 fatal errors when `make -j' is involved. Improve error message.
922 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
924 * doc/autoconf.texi (Here-Documents): We now know more about
925 the variable expansion in here documents bug.
926 Thanks to Tim Rice and Stepan Kasal.
928 * doc/autoconf.texi (Making testsuite Scripts): Add an example
929 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
931 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
933 * tests/autotest.at (Multiline command from M4 expansion):
934 No failure to be expected if the shell quotes newlines in
935 commands in the `set -x' output. Report by Tim Rice.
938 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
940 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
941 expansion in the here-documents used by config.status, as that
942 runs afoul of the Korn shell version M-12/28/93d bug described in
943 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
944 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
945 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
947 2006-05-23 Jim Meyering <jim@meyering.net>
949 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
950 Fix typo introduced with 2006-04-02 change. It reversed the sense
953 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
955 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
956 ac_dB slightly, to save bytes in the script.
957 Max out at 50 lines, rather than 96; this is more likely
958 (though not guaranteed) to avoid obscure 'sed' failures.
960 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
962 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
963 `tr -d -' as bad option argument. Work around this by deleting
964 an unrelated character.
965 Report by Tim Rice <tim@multitalents.net>.
967 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
968 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
969 Stepan Kasal <kasal@ucw.cz>
971 * doc/autoconf.texi (Particular Programs): Do not promise that
972 we always prefer the GNU version of the program, and that we
973 search according to PATH; both rules can have exceptions.
974 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
975 AC_PROG_SED. Move descriptions of limitations
976 to the Limitations of Usual Tools section.
977 (Limitations of Usual Tools) <sed>: Mention script length
978 limitations with Solaris /usr/ucb/sed.
979 <grep>: Fix wording for empty alternative. Mention that -c and
980 -l should not be combined, and that -E and -F should not be
983 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
984 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
986 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
987 limits in Solaris 8 /usr/ucb/sed by testing a long script.
989 2006-05-22 Stepan Kasal <kasal@ucw.cz>
991 * doc/autoconf.texi (Defining Symbols): Literal parameter of
992 AC_DEFINE is now passed to m4_pattern_allow.
993 * NEWS: Mention that; likewise for AC_SUBST.
994 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
995 the parameter to m4_pattern_allow.
996 * tests/tools.at: Add a check for that.
998 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1000 * lib/autoconf/status.m4: Fix typos.
1002 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1004 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1005 only the files that this macro generates.
1007 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1009 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1010 the HP-UX sed limitation of 99 commands, labels do not count.
1011 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1013 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1015 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1017 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1018 Import the following fix from coreutils:
1020 2006-01-13 Jim Meyering <jim@meyering.net>
1022 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1023 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1024 not double-quote uses of that variable, to accommodate the rare
1025 case in which getmntent is available in none of the libraries
1026 checked. This happens at least on FreeBSD 5.0.
1028 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1030 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1031 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1032 some other programs unwisely rely on these undocumented vars.
1033 But put in warning comments about them.
1034 Problem reported by Ralf Wildenhues in
1035 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1036 * NEWS: Document that these variables are intended to go away.
1038 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1040 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1041 and set the language to C++ (analogous to the equivalent Fortran
1044 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1045 * doc/autoconf.texi (C++ Compiler): Document it.
1046 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1049 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1051 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1052 that caused config.status to generate 100-command sed scripts; the
1053 portable limit is 99.
1055 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1057 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1058 variable `ac_d' instead of `d' to avoid infringing namespace.
1059 Report by Ralf Menzel.
1061 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1063 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1064 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1065 * tests/tools.at (autoconf: subdirectories): New test, taken from
1066 the corresponding problem report by Ralf Wildenhues in:
1067 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1069 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1070 Quote some uses of shell variables if they might suffer unexpected
1071 globbing. This doesn't fix all instances of quoting problems that
1072 I found, just the easy ones that look safe.
1073 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1074 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1075 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1076 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1077 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1078 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

1084 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1086 * bin/autoreconf.in ($help): Reword according to the manual.
1087 Suggested by Olly Betts.
1089 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1090 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1092 * bin/autoreconf.in: Pass the directory argument to
1093 `require_configure_ac'. Fix comment.
1094 * tests/torture.at (Configuring subdirectories): Expose this.
1095 Reported by Olly Betts.
1097 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1099 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1100 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1101 Automake as follows:
1103 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1104 `$configure_in' instead of `configure.in', to preserve
1105 directory component.
1107 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1109 * config/config.guess, config/config.sub, config/texinfo.tex,
1110 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1112 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1114 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1115 test for C99 conformance; (bool) 0.5 is an integer constant
1116 expression, but (bool) -0.5 is not. Problem reported by Fedor
1117 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1119 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1121 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1122 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1123 Warn about obsolete install-sh files. Remove stray sentence
1124 fragment and fix cross reference.
1125 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1126 install -d; this undoes the 2006-05-10 change.
1127 (MKDIR_P): Mark with AN_MAKEVAR.
1128 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1129 that we don't require $INSTALL to be thread-safe. Move comments
1130 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1131 of AC_PROG_INSTALL. Output a message saying that we're checking
1132 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1133 MKDIR_P instead of AC_SUBST.
1134 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1135 Special magic for MKDIR_P, too.
1136 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1138 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1140 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1142 Sync from Automake, as follows:
1144 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1145 * config/install-sh: Initialize IFS, so field splitting isn't
1147 * config/mkinstalldirs: Likewise.
1148 * config/missing: Remove superfluous quotes. Replace all uses of
1149 `[' by `test', for consistency, and for..
1150 * config/missing (sed_minuso, sed_output): New variables.
1151 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1152 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1153 Fixes `missing' to detect `--output' for help2man. Fixes
1154 PR automake/483. Report by Dennis J. Linse.
1155 (autom4te): Document in `missing --help'.
1157 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1159 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1160 * config/install-sh: Don't use 'path' to talk about file names,
1161 as per GNU coding standards. Close a race condition reported by Ralf
1162 Wildenhues and Stepan Kasal. There is still a race condition
1163 on hosts that predate Posix 1003.1-1992, but we can't help this.
1164 Don't mishandle weird characters like space on pre-Posix hosts.
1165 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1166 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1167 AC_PROG_MKDIR_P from AS_MKDIR_P.
1168 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1169 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1170 earlier editions are not (including Automake 1.8.3).
1171 Do not suggest mkinstalldirs for thread-safety.
1172 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1173 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1174 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1175 presence of special characters and race conditions.
1176 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1177 in Autoconf's name space.
1179 2006-05-10 Bruno Haible <bruno@clisp.org>
1180 and Paul Eggert <eggert@cs.ucla.edu>
1182 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1183 from Automake with minor changes.
1184 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1186 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1188 * config/install-sh: Update to Automake CVS version, as follows:
1189 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1190 * lib/install-sh: Simplify the expr implementation of dirname.
1191 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1192 * lib/install-sh: Handle --, and diagnose unknown options.
1194 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1196 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1197 `./autom4te' to create `./testsuite', since the `all' target
1198 will ensure its presence, but `installcheck' should not create
1199 the uninstalled wrappers.
1201 * tests/torture.at (Unusual Automake input files): Skip if we
1202 detect automake < 1.8.
1204 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1206 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1207 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1208 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1211 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1213 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1214 munge (multiple) white space and other oddities.
1215 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1216 single quotes in variable assignment.
1217 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1218 and similar failures by adding multiple spaces, tabs, and other
1220 Report and different test suggested by Francesco Romani
1221 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1223 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1224 single quotes, we only need to search for single quotes; this
1225 both simplifies the search pattern, and makes us less
1226 susceptible to `echo' variations for arguments not containing
1228 (_AC_ARG_VAR_VALIDATE): Likewise.
1230 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1232 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1233 `$*' and IFS concatenation issue with traditional shells and
1234 bash-2.04. Report by Seanster@Seanster.com.
1236 2006-05-03 Bruno Haible <bruno@clisp.org>
1238 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1239 precisely which Mac OS X versions have the od problem.
1241 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1243 * doc/autoconf.texi: Use @option systematically.
1245 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1246 and Bruno Haible <bruno@clisp.org>
1248 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1250 (Integer Overflow): Mention the special case of integer division
1253 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1255 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1256 traditional shells like the Solaris one that do not use the
1257 first IFS character for assembling `$*'.
1258 Prompted by a related report from autoconf_bug@nro.ca.
1260 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1261 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1263 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1264 Mention more problems with the -e option.
1266 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1269 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1271 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1272 in URLs to improve DVI formatted output (requires texinfo 4.6).
1273 (System Services, Systemology, Shellology): Likewise.
1274 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1277 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1279 (Runtime): Fix macro argument names to match description:
1280 `action-if-found' -> `action-if-true' and similarly.
1281 (Obsolete Macros): Likewise.
1282 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1283 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1284 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1286 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1288 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1291 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

1316 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1318 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1319 since as_me isn't set yet.
1321 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1323 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1324 a few minor bugs in this area.
1326 * doc/autoconf.texi (Programming in M4sh): Comment out the
1327 documentation of AS_BASENAME, for now.
1328 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1329 (Limitations of Builtins) <basename>: Do not refer to
1331 * bin/autoconf.as (me): Don't use AS_BASENAME.
1332 (dir): Remove the unused variable.
1333 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1334 AS_DETECT_REQUIRED. All uses changed.

1347 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1349 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1350 of "run time" and "run-time" changed to "runtime", for consistency.

1357 with more accuracy and detail.
1359 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1361 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1362 Archive is not officially `GNU' any more. Update URL.
1363 (Defining Directories): Likewise
1364 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1366 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1368 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1369 newline from the `trap' code to finish `config.log'; the NetBSD
1370 /bin/sh resets the exit status after an empty command, as
1371 documented in doc/autoconf.texi.
1372 Reported by Dalibor Topic <robilad@kaffe.org>.
1374 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1376 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1377 Suggested by Bruno Haible.
1379 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1381 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1382 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1383 Instead, just list the shells that we know work.
1384 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1385 changed. Be more cautious about the _cv_ variable.
1386 * tests/tools.at (Syntax of the shell scripts): Check the
1387 _cv_ variable once, at first, to avoid an internal autoconf error
1388 when sh -n does not work.
1390 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1392 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1394 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1396 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1397 use ">&-" since we're only 99.999% sure that this is portable,
1398 and since the MinGW bug is fixed in a different way.
1399 * lib/autotest/general.m4 (AT_INIT): Likewise.
1401 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1403 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1404 before opening config.log, to avoid hitting a bug on MinGW.
1406 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1408 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1409 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1410 This works around a MinGW bug reported by Eric Paire.
1411 Make sure that all writes to the log file append to it,
1412 rather than possibly losing data.
1413 * lib/autotest/general.m4 (AT_INIT): Likewise.
1415 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1417 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1420 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1424 * configure.ac (AC_INIT): Bump to 2.59d.
1426 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1430 * Makefile.maint (news-date-check): Do not require a leading `*'
1431 before the release date in NEWS.
1433 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1434 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1436 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1437 the instantiated file do not contain the string 'datarootdir'
1438 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1439 @mandir@, replace the reference '${datarootdir}' by the value.
1440 * tests/torture.at (datarootdir workaround): New test.
1441 * NEWS: Advertise this temporary fixup.
1442 Based on a patch by Bruno Haible, reported and analyzed by
1443 Paul Eggert and Noah Misch.
1445 2006-04-12 Eric Blake <ebb9@byu.net>
1447 * tests/autotest.at (Debugging a failed test): Fix comment.
1449 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1451 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1452 all the changes since 2006-04-07.
1454 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1456 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1457 succeeded, but `ln -s file dir' failed, take care to remove the
1458 leftover target before the next test, to prevent its spurious
1459 failure; also make sure `ln file dir' works before selecting it.
1460 Thanks to Keith Marshall for pointing this out.
1463 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1464 assignments in `at_debug_args', so that we put them correctly
1465 in the `run' script.
1466 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1467 Reported by Eric Blake.
1469 2006-04-11 Eric Blake <ebb9@byu.net>
1471 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1472 top-level tests after micro-suite has been run. Used in...
1473 (Debugging a successful test, Debugging script and environment),
1474 (Debugging a failed test): ...these new tests. The first of these
1476 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1477 macro, split out from...
1478 (AT_INIT): ...here, so that using -d also generates a run script.
1479 Document that -d inhibits top-level logging.
1480 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1481 inhibits top-level logging; debug scripts are created.
1483 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1485 * tests/autotest.at (Empty test, Empty check): New test to check it.
1487 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1490 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1492 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1493 the files if a problem appears. Make the empty *.at files
1494 read-only, too. Proposed by Ralf Wildenhues.
1496 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1498 * config/Makefile.am: Add comment to force updated Makefile.in.
1500 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1501 space only patch to this file, this patch causes the Makefile.in
1502 files that include freeze.mk to be updated, and thus have a
1503 newer time stamp again, which in turn makes a pristine CVS
1504 checkout have correct time stamps.
1506 * Makefile.maint (cvs-sv): New macro, to be used..
1507 (config.guess-url_prefix, config.sub-url_prefix)
1508 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1509 point to CVS text checkout of Gnulib files.
1510 (copyright-check): Bump current year.
1511 (announcement): Do not hard-wire `./announce-gen'.
1512 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1514 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1516 (wget_files): Update config.guess, config.sub, texinfo.tex by
1517 `wget-update', now that their URLs work again.
1519 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1521 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1522 Problem noted by Paul D. Smith.
1524 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1526 * doc/autoconf.texi: Remove unused words from word list.
1527 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1528 .x-sc_trailing_space: New files.
1530 * doc/standards.texi: Sync from gnulib.
1532 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1533 `LIBOBJDIR' as experimental.
1535 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1536 with a target directory; it's internally implemented as `cp'
1537 anyway, but since Autoconf advertises the possibility to use
1538 a target directory when LN_S is `ln -s', we need to find out.
1539 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1540 analyzed by Keith Marshall <keith.marshall@total.com>.
1544 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1546 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1547 confdefs.h as-is. In general, if it has backslash-newline or the
1548 like, then it doesn't work either to sort or to remove empty
1551 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1553 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1555 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1557 * lib/autom4te.in (Automake-preselections): Preselect
1560 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1562 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1563 apostrophe within a single-quoted string, as this is the usual
1564 tradition and is easier to read than '"'"'. Don't rely on the
1565 shell treating "$/" like '$/'. Use a more-consistent indenting
1568 2006-04-09 Eric Blake <ebb9@byu.net>
1570 * tests/autotest.at (Backquote command substitution),
1571 (Multiline backquote command substitution): Remove mistaken
1572 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1574 (Parenthetical command substitution, Multiline parenthetical
1575 command substitution): here.
1577 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

1610 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1611 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1612 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

1639 2006-04-08 Stepan Kasal <kasal@ucw.cz>
1641 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1642 of the warning introduced by the 2001-08-28 change.

1647 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
1648 variables shall be overriden by the cache.

1650 that contains braces.
1652 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1654 Revert the patch from 2006-04-01 and only improve
1655 _AS_DETECT_BETTER_SHELL:
1657 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1658 skip nonexistent directories.
1659 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1660 only shell candidates which exist.
1661 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1662 * lib/autotest/general.m4 (AT_INIT): No need to give three
1663 parameters to _AS_PATH_WALK.
1665 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1666 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1668 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1669 distinguish m4sugar macros.
1670 * tests/tools.at (autoupdating with aclocal and m4_include):
1671 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1672 test case by Noah Misch <noah@cs.caltech.edu>.
1674 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1676 Revert my change from 2006-03-17, in other words:
1677 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1679 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1680 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1683 2006-04-07 Eric Blake <ebb9@byu.net>
1685 * doc/autoconf.texi (Programming in M4sh): Document that
1686 AS_MKDIR_P exits the script on failure.
1687 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1689 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1691 * config/elisp-comp, config/install-sh, config/mdate-sh,
1692 config/missing, config/mkinstalldirs: Sync from Automake.

1706 Eric Blake <ebb9@byu.net>,
1707 Paul Eggert <eggert@cs.ucla.edu>,
1708 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1710 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1711 whether `set' quotes correctly: redirect stderr of the tested
1712 `set', and use a subshell, for Ultrix; use `sed' instead of
1713 `grep' for zsh `set' which may write binary output; match only
1714 at the beginning of a line, to avoid false positives.
1715 In order to avoid false positives by unrelated variables with
1716 multiline content, put the dump algorithm in a subshell and
1717 unset all variables containing newlines (except some which are
1718 special to the shell). Warn about cache variables that are
1721 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1723 * config/config.guess, config/config.sub, config/texinfo.tex:
1726 * tests/mktests.sh: Reword comments.
1728 * tests/mktests.sh: Only skip internal macros starting with

1735 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1737 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1738 shell issue with double-quoted command substitutions of native

1763 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1764 ac_config_<foo>s again, sometimes normalized, sometimes not.
1765 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1766 (AC_CONFIG_COMMANDS): Do not do so here.
1767 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1768 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1769 2005-07-25 rewrite. Noticed by Noah Misch.
1771 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1772 _AC_PRESERVE_HELP_ORDER, ...
1773 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1775 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1776 inside m4_expand_once; it is redundant.
1778 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1779 for --help from Cygnus `configure.'
1781 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
1783 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up

1791 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
1792 Noah Misch <noah@cs.caltech.edu>
1794 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1795 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1796 * doc/autoconf.texi (Help Formatting): New node.
1797 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1799 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1801 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1802 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1803 lib/autoconf/types.m4, lib/autotest/general.m4,
1804 tests/mktests.sh, tests/torture.at: White space cleanup:
1805 remove some SPACE before TAB, or add quoting ('' or @&t@).
1807 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1809 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1811 2006-04-05 Eric Blake <ebb9@byu.net>
1813 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1814 empty test suite works.
1815 * tests/autotest.at (Empty test suite): Remove xfail.
1817 2006-04-05 Noah Misch <noah@cs.caltech.edu>

1820 TAGS to ac_config_<foo>s.
1821 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1822 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1823 normalizing it, consistent it with previous releases.
1824 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1826 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1828 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1829 Use simplified args that Eric Blake originally suggested.
1831 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1833 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1834 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1835 Use 'comm' rather than N instances of grep; this also fixes a bug
1836 whereby substrings were incorrectly matched, causing us to not
1837 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1838 (exclude_list): Exclude empty macros.
1839 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
1841 Use awk rather than grep -E or egrep, to avoid
1842 portability problems with regular expressions containing newlines.

1850 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
1851 a subdirectory subject to Cygnus `configure'.
1852 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
1854 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
1855 report request when we have no AC_PACKAGE_BUGREPORT.
1857 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1861 * tests/mktests.sh: Update copyright year in the header of the
1864 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
1865 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
1866 typedef'ed restricted pointer, to catch a compiler bug on
1867 HP-UX 11.x, and fix warnings so it passes with -Werror.

2711 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2712 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2713 by the function rather than ignoring it.
2714 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2715 comparing its address. Intel's interprocedural optimization was

2734 Stepan Kasal <kasal@ucw.cz>
2736 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2737 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2738 make its content writable before removing it. Remove an errorneous

2765 suggested by Ben Elliston. Handle weird characters correctly.
2767 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2769 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2770 calls, so that the final expansion of this macro is shorter.
2771 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2772 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2773 the cleanup there. Use AS_VAR_* macros, to be more general.
2774 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2776 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2778 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

2801 "if $undefined_var;" succeeds with my shell.
2803 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2804 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

2815 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2816 some evil values and relying on the fact that $* concatenates the
2817 parameters by the first character from IFS.

2823 first header appears, define AH_HEADER.
2824 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2825 Update limitations about when to call AC_CONFIG_HEADERS.
2826 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2827 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2828 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2829 ``Configuration Actions''; fix their index entries.
2831 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2832 options correctly. Process N-M as M-N if M is smaller than N.
2833 Process ranges correctly so that N-N will run only N.
2834 Sort and uniquify the tests that will be run. If there is more
2835 than one test, reinsert the banners for the tests.
2836 * tests/autotest.at (Keywords): Unmark XFAIL.
2838 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2840 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2841 before passing the macro name to AH_TEMPLATE.
2843 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2844 now opens log after option processing; in particular, --version
2845 and --help do not touch config.log.
2847 * Makefile.maint: Revert the change from 2005-08-12.
2849 2005-08-22 Stepan Kasal <kasal@ucw.cz>

2857 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2858 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2861 * doc/autoconf.texi (Defining Symbols, Changed Results):
2862 Prepend to LIBS, not append, in examples.
2864 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2866 When building in place, set srcdir="."; suggested by Tim Van Holder.
2868 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2869 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2870 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2871 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2872 does not mean "no --srcdir option".
2874 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2876 * tests/autoscan.at (autoscan): New file.
2877 * tests/suite.at: Use it.

2885 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2886 add "2>&1"; gzip 1.2.4 prints help on stderr.
2888 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2890 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2891 was pushdef'ed twice while popped only once. Push it only once.

2906 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2908 Rewrite substantial part of lib/autoconf/status.m4.
2909 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2910 and CONFIG_COMMANDS are not processed in four separate loops.
2911 Instead, there is one main loop. This alows that the common code
2912 is expanded only once, thus config.status (and configure) is smaller.
2914 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2915 the AC_LIST_FILES and cousins macros are no longer used.
2917 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2918 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2919 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2920 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2921 contain the initialization, nor the for loop, nor the associated
2922 commands; all these go to ...
2923 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2924 _AC_OUTPUT_CONFIG_STATUS.
2925 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2926 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2927 (_AC_OUTPUT_FILE): The creation of the sed script ...
2928 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2929 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2930 _AC_OUTPUT_MAIN_LOOP.
2931 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2932 _AC_CONFIG_COMMANDS): Use ...
2933 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2934 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2935 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2936 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2937 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2938 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2940 (_AC_CONFIG_UNIQUE): Update.
2941 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2942 Replaced by this ...
2943 (_AC_LIST_TAGS): ... new common macro.
2944 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2945 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2946 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2947 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2948 this didn't belong to the `config commands' section.
2949 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2950 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2951 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2952 to the `config commands' section either.
2953 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2954 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2956 ... and many changes to the comments nearby.
2958 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2959 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2960 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2961 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2962 (#define header templates): The comment at the top of the generated
2963 header now includes the name(s) of the source file(s).
2965 Several unrelated small changes:
2967 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2968 parameter to AC_DIAGNOSE.
2969 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2970 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2971 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2972 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2974 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2975 in AC_OUTPUT doesn't double-quote it either.
2976 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2979 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2981 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2982 versions of Portland Group compiler produce single- and double-quoted
2983 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2984 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2986 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2988 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2989 This is a corrected version of yesterday's patch.
2991 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2993 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2994 path, too; insert a "===" to emphasize the line.
2996 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2997 ac_cv_build_alias to ac_build_alias.
2998 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3000 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3001 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3002 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3003 (AC_ARG_VAR): ... here.
3004 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3007 Keep a list of all precious variables and process them with one simple
3008 for loop, instead of expanding all commands, or, OTOH, complicated
3009 processing of output of "set".
3010 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3011 variable names in new macro...
3012 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3013 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3014 a loop to assign all ac_env_* and ac_cv_env_* variables.
3015 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3017 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3018 its value to shell variable ac_precious_vars and call
3019 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3020 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3021 _AC_ARG_VAR_VALIDATE.
3023 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

3041 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3042 They are generated by the Tru64 v5.1B shell.
3044 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3046 Fix my changes from 2005-07-01; reported by Noah Misch.

3051 Fix cases when the varsions of Autoconf and Autotest don't match.
3052 Reported by Noah Misch.

3054 at_top_builddir, for compatibility with older autotest.
3055 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3056 is not set, use at_top_builddir, for compatibility with older
3057 versions of autoconf.
3059 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3061 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3062 Problem reported by Patrick Welche.
3064 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3066 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3067 sed substitution command, so that we allow | in program prefixes
3068 and program suffixes. (& is a problem anyway; we're not fixing
3070 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3071 configure_input, top_builddir, srcdir, etc.
3072 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3073 PATH_SEPARATOR in AUTOTEST_PATH.
3075 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

3083 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
3084 directories with weird names. Apparently some people like living
3085 on the edge. However, improve the test that "pwd" actually does
3086 report a name for the working directory.

3106 document to output the default config_* lists to config.status.
3107 Don't recognize option --file, if the functionality is not there.
3108 Likewise for --header; moreover, recognize --he and --h as shortcuts
3109 for --help in that case.
3111 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3112 matches the order of execution. No code changed.

3134 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3135 (AC_SUBST): Call it.
3136 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3137 the directory specific variables; but don't call it for configure_input.
3139 2005-06-28 Derek Price <derek@ximbiot.com>
3141 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3144 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3146 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3147 directory have inherent problems with special characters like spaces,
3148 due to limitations in Make syntax. Problem reported by Alexandre
3150 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
3151 Also, fix Tru64 porting problem with shell patterns,

3163 from Justace Clutter.
3164 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
3165 variable into diagnostic. Make the diagnostic an error, not a warning,
3166 because we really don't support spaces and suchlike in dir names.
3167 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3168 Don't worry about backslashes in srcdir; it can't happen now.

3212 * doc/autoconf.texi:
3213 Don't mention Solaris versions so much, if a
3214 problem is common to all extant versions of Solaris. Say "SunOS
3215 4" instead of "SunOS" for SunOS 4.
3216 (awk): Mention more of the limitations of traditional Awk.
3217 (cat): Don't talk about cat -v.
3219 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
3221 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
3222 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

3233 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3235 * doc/autoconf.texi: "filesystem" -> "file system".
3236 "behaviour" -> "behavior".
3237 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
3238 * lib/autoconf/general.m4: Omit blank after ":" sed command,
3240 * lib/m4sugar/m4sh.m4: Likewise.
3241 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
3242 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
3244 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
3245 (.x.1): Ignore the time stamp in the .TH line when deciding whether
3246 to update the man page. That way, we don't have to check in new

3257 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
3259 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3260 -u, since it outputs chatter if the input files are the same.
3261 Problem reported by Ralf Menzel.
3263 2005-06-08 Derek Price <derek@ximbiot.com>
3265 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3266 renaming them since they are about to be redefined anyhow.
3268 2005-06-08 Derek Price <derek@ximbiot.com>
3270 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3271 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3272 Move m4_undefine to alphabetical order.

3276 * README: Recommend GNU M4 1.4.3 or later.
3277 * doc/autoconf.texi (Introduction): Likewise.
3278 Reword to avoid some formatting glitches.
3279 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3280 Clarify explanation of HP compiler bug.
3281 Redo example output tp match current CVS snapshot.
3282 Use @example.org in email addresses when the examples
3283 might get inadvertently cut-and-pasted into user code.
3284 Remove example of autom4te usage that doesn't seem to work now.
3285 Use modern AC_INIT (except when the example is meant to be
3286 shown with Autoconf 2.13).
3287 Update ksh info for Solaris 9 and later.
3289 Modernize description of Automake versions a bit.
3290 Don't claim a future version of Autoconf is near.
3291 * doc/install.texi: Reword to avoid some formatting glitches.
3293 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3295 * doc/autoconf.texi: Add [] to examples, so that the manual
3296 follows its own advice about quoting better.
3297 Reword to avoid some formatting glitches.
3298 * doc/installt.exi: Reword to avoid some formatting glitches.
3300 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3301 Tru64 ksh pattern matching bug. Reported against Libtool by
3302 Albert Chin <libtool@mlists.thewrittenword.com> and
3303 Nicolas Joly <njoly@pasteur.fr>.
3305 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3307 m4_cdr of one-member list was [[]] (one-member list containing an
3308 empty string) instead of [] (an empty list. Callers were skewed to
3309 match this misbehaviour. As a consequence of this:
3310 - m4_foreach([x], [], [foo]) expanded to `foo', while
3311 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3312 This bug has been fixed:
3314 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3315 expand to an empty string; print error msg if called without
3317 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3318 misbehaviour; handle [] and [[]] correctly.
3320 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3322 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
3323 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
3324 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
3326 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3328 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3329 swallow records with more than 99 fields.
3330 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3331 parse the long line.
3333 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3335 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3336 swallow literals longer than 399. Reported by Ralf Wildenhues.
3337 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
3338 to workaround this limitation.
3340 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3342 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3343 to gfortran, and make these the first two compiler names
3344 checked (following the general autoconf preference for gcc).
3346 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3348 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3349 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3350 (testsuite): Make sure autotest.m4f is up-to-date before using it.
3352 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
3354 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3355 expression of unbounded size when processing the --list
3356 option. This runs afoul of a limit of 399 bytes per regular
3357 expression on AIX. Problem reported by Ralf Wildenhues.
3359 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
3361 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
3362 * doc/autoconf.texi (Particular Headers): Reword example
3363 for multiline stdbool replacement.
3364 (Setting Output Variables): Reword text a bit. Don't
3365 give all the details about |#_!!_#|.
3366 Reword description of line replacement.
3368 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3370 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3371 now contain newlines, and substituted files must be referenced on
3372 a line alone; the sed scripts to substitute them are now very
3374 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3375 commands can be put in a sed script portably.
3376 * doc/autoconf.texi (Setting Output Variables): Document above
3377 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3378 use of multiline substitution.
3379 * tests/torture.at: No longer expect substitution of newline to fail.
3381 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
3383 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
3384 From Ralf Menzel (trivial change).
3386 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
3388 * tests/local.at: Don't attempt to check for negated character
3389 classes in shell scripts. The test was too brittle.
3391 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3393 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3394 * doc/autoconf.texi (Limitations of Builtins): Document this
3397 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3399 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3400 common code; used in many places in the tree.
3401 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
3402 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
3404 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
3406 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
3407 messages when ac_unique_file is not found.
3408 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3409 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3410 commands, for consistency with AC_MSG_ERROR and such.
3412 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3414 * bin/Makefile.am: Merge the two rules for creating scripts.
3416 2005-05-23 Stepan Kasal <kasal@ucw.cz>
3418 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
3419 obsolete; it was never documented.
3420 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
3422 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3424 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3425 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3426 (ac_top_builddir): ... this ...
3427 (ac_top_build_prefix): ... to this; the old name is also kept, for
3428 backward compatibility.
3429 (ac_top_builddir_sub): New variable, without the trailing slash,
3431 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3432 * doc/autoconf.texi (Configuration Actions): Rename
3433 ac_top_builddir to ac_top_build_prefix.
3434 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
3435 at_top_builddir to at_top_build_prefix.

3438 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3440 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
3443 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3445 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3446 argument to m4_foreach. I guess it was necessary in the past,
3447 but I think it's a no-op now.
3449 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3451 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3452 ``cat <<_ACEOF'' commands to one.
3453 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3454 * lib/autoconf/status.m4: On various places, use expr instead of
3456 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3457 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3458 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3460 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3461 the wrong patterns between ``case'' and ``esac.'' The previous
3462 code had false positives.
3464 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3466 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

3509 2005-05-13 Stepan Kasal <kasal@ucw.cz>
3511 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
3513 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3514 enough arguments, similarly as in m4_bpatsubsts.
3516 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3518 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
3521 2005-05-11 Stepan Kasal <kasal@ucw.cz>
3523 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3524 for absolute directory names in one loop.
3525 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3526 abbreviations of --version and --debug.
3528 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3530 * doc/autoconf.texi (Autoconf Language): Be more precise about
3531 quoting rules. Problems noted by Stepan Kasal.
3532 Also, throughout this document, be more careful about white space.
3533 "blank", "white space", and "space" all have different meanings
3534 and we should be careful to say what we mean.
3536 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3538 Fix C++ related problems reported by Werner Lemberg.
3539 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3540 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3541 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3542 avoid problems with C++ and throw.
3543 * tests/compile.at: .cpp, not .cc.
3545 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3547 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3549 * doc/autoconf.texi (Generic Functions): Typos.
3551 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3553 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3554 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3555 set by latest automake.
3557 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3559 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3560 outputs 0 on GNU/Linux these days.
3562 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3564 * doc/autoconf.texi (Autoconf Language): Add more description
3565 about quoting heuristics.
3566 (Limitations of Builtins): Describe "set -" problems.
3568 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3570 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3573 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3574 by AC_DEFINE; it was a mistake.
3575 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3577 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3579 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3581 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3583 * doc/autoconf.texi (External Software): Quadrigraphs are not
3584 processed correctly in AS_HELP_STRING; avoid this in the examples.
3585 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3586 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3587 comment and reduce m4_default([foo], []) to [foo].
3588 (m4_strip): Update the explanation.
3590 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3592 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3593 Remove core.conftest.* too; it's generated by Tru64 5.1.
3594 Problem reported by Jennis Pruett.
3595 * lib/autoconf/functions.m4
3596 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3597 Don't bother to remove core files; AC_RUN_IFELSE should do that
3600 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3602 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
3604 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
3606 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

3616 * doc/autoconf.texi (External Software, Package Options): Add
3617 examples showing how to implement --with-* and --enable-* options.
3619 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3621 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3622 as well as configure.in. Problem reported by Gregorio Guidi.
3624 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3626 * doc/autoconf.texi (Particular Functions): Use gnulib's current

3640 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3642 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3644 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3645 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3646 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3647 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3648 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3650 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3652 * NEWS: The configure command now warns you if you attempt to use
3653 a directory whose name contains a special character like space,
3655 * doc/autoconf.texi (Installation Directory Variables): Allow
3656 "," in file names. Do not use \@; it's not a portable regexp.
3657 * bin/Makefile.am (edit): Likewise.
3658 * lib/Makefile.am (edit): Likewise.
3659 * tests/Makefile.am (edit): Likewise.
3660 * tests/semantics.at: Likewise.

3663 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3664 * doc/autoconf.texi (File System Conventions): Warn about
3665 unportable file names.
3666 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3668 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3669 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3670 ac_pwd, and quote srcdir.
3671 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3673 * doc/autoconf.texi: Fix some systematic formatting problems.
3674 ".)" needs a following @: if not at the end of a sentence, and
3675 similarly for "!)". "etc." should be preceded by a comma.
3676 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3678 2005-03-22 Bruno Haible <bruno@clisp.org>
3680 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3681 argument is often called 'build-aux'.
3683 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3685 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3686 macro AC_TRY_LINK is obsolete.
3687 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3690 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3692 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3693 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3694 from a Common Lisp's `cl'.
3695 (AC_PROG_CXX): Behave according to the documentation: don't
3696 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3697 make the variable CCC precious; use `cl.exe', not `cl'.
3699 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3700 Alexandre Duret-Lutz <adl@gnu.org>
3702 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3703 /dev/null, as "configure" shouldn't read stdin, and this insulates
3704 us from problems (e.g., when testing for "cl"). Also, do this
3705 redirection before invoking "hostname" or "uname", and keep the
3706 original input stream available via...
3707 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3708 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3709 bother with "</dev/null" since it's now done at the top of
3711 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3712 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3713 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3714 * doc/autoconf.texi (File Descriptor Macros): New section.
3715 (Printing Messages): Mention it.
3716 * tests/base.at (Input/Output): New test.
3718 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3720 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3721 newline if neither \c nor -n work, as that would output two
3722 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3724 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3726 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3727 This causes that any required macros inside will get before the if.

3730 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3732 Undo previous change, except keep the change to
3733 lib/autoconf/programs.m4 that replaced grep with shell
3734 pattern-matching. This is because net-snmp configure reads stdin.
3735 Reported by Noah Misch.
3737 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3739 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3740 from /dev/null, as "configure" shouldn't read stdin, and this
3741 insulates us from problems (e.g., when testing for "cl").
3742 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3743 before invoking "hostname" or "uname".
3744 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3745 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3746 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3747 "</dev/null" since it's now done at the top of 'configure'.
3748 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3749 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3750 Also, replace grep with shell pattern-matching, to save a process.
3752 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3754 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3755 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3756 avoid thinking that Allegro Common Lisp's "cl" command is a C++

3774 Sort environment variable names.
3775 Mention that shells no longer inherit IFS.
3776 Don't recommend PATH_SEPARATOR=';' so strongly.
3777 Mention that $RANDOM might expand to the empty string.
3778 "symlink" and "soft link" -> "symbolic link".
3779 Improve mktemp description (reported by Bruno Haible).

3855 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3857 Try not to generated lines of unlimited length, as POSIX places a
3858 2047-byte limit on line length of portable text files.
3859 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3860 Use newline as a separator, not space.

3895 Modified from a suggestion by Stepan Kasal.
3897 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

3918 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3919 Update the long comment explaining it.
3921 m4_require no longer writes an ``is required by'' line to the
3922 execution stack. It contains only one bit of non-redundant
3923 information: that the macro was required, not called. And even
3924 this bit is useless in most situations: have you ever met a macro
3925 which both calls and requires the same macro?
3927 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3928 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3933 execution stack; slightly improve the out-of-a-defun error message.
3934 (_m4_divert_grow): New macro, counter for the temporary diversions.
3935 (_m4_require_call): Use it.
3936 * tests/m4sugar.at (m4_require): Expect output without the
3937 ``is required by'' messages.
3939 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

3975 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3976 Warn about newline stripping in `` and $(). Update Solaris
3978 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3979 X insulates us from future changes to Posix.
3980 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3983 2005-01-19 Stepan Kasal <kasal@ucw.cz>
3985 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

4005 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4007 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

4029 (_m4_divert_n_stack): New macro; the expansion is
4030 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4032 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4033 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4034 stored in _m4_divert_diversion or _m4_divert_dump.
4035 (m4_divert_pop): When the parameter is given, compare the symbolic
4036 name with the last diversion pushed on the stack. Previously, the
4037 current diversion was compared with the numeric value of the
4038 diversion given as the parameter.
4039 (m4_require): If the macro hasn't been expanded yet, call ...
4040 (_m4_require_call): this new macro.

4073 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

4254 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

4322 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
4323 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

4345 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4347 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4348 "char c = '\200';" rather than "char c = 0x80;" as the

4350 overflow on signed char hosts.
4352 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4353 to -qlanglvl=ansi. We don't want to disable extensions.

4466 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4467 "/usr/include", clear ac_x_includes instead of leaving it as "no"

4535 This isn't a complete fix but it's an improvement.
4537 * bin/autoconf.as (autom4te_options): New var.
4538 Use it instead of appending to AUTOM4TE, so that we can allow
4539 spaces in the build directory's absolute name.
4540 * bin/autoheader.in ($autoconf): Allow spaces in file names.

4573 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4575 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4577 * lib/autom4te.in (Automake-preselections): Preselect

4594 useful for pkdsh, too.
4596 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4598 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require

4613 names like "aux". Problem reported by Eric Blake.
4615 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4616 by zero instead of array size, so that we can use any arithmetic
4617 constant expression (instead of requiring an integer constant
4618 expression). This allows us to test expressions like DBL_MAX <
4619 LDBL_MAX, which didn't conform to the C standard using the old
4621 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4622 now that we can do floating-point tests at compile time.
4624 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4626 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4627 and LDBL_EPSILON, as the resulting expression isn't an
4628 integer constant expression and violates the C standard.
4629 Problem reported by Nelson H. F. Beebe. Also, check
4630 for "L" suffix, and check that long double doesn't have
4631 worse range or precision than double, that mixed-mode
4632 arithmetic doesn't generate a diagnostic, that double
4633 constants fit in long double.

4659 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4661 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4662 change). Patch reported by Ralf Wildenhues in
4663 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4665 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4666 function F exists if the compiler and linker let you compile an
4667 expression like (F != 0). Recent versions of GCC optimize away
4668 the reference to F in that case, since every function address must
4669 be nonzero, so the link succeeds even if F does not exist.
4670 Problem reported by Manu in
4671 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4673 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4674 "Unix". Many uses changed.
4675 (Limitations of Builtins): Explain better why the ! command isn't
4678 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4680 * lib/autom4te.in (Automake-preselections): Preselect
4681 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4683 2004-05-19 Kevin Ryde <user42@zip.com.au>
4685 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4686 referencing AC_FUNC_STRERROR_R.
4688 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4689 note pessimistic assumption when cross compiling.
4691 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4693 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4694 (until 2004) invoked subcommands with sh -e, contra POSIX.
4695 Reported by Kevin Ryde.
4697 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4699 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4700 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4701 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4702 `test -f " /usr/bin/grep"', which _always_ failed.
4703 (AC_PROG_SED): Ditto bogus PATH fix.
4704 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4705 requires that grep correctly supports _multiple_ `-e' options, rather
4706 than stating only that grep should accept `-e'.
4708 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4710 Port to C99, which requires that 'exit' be declared.
4712 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4713 to ensure that stdlib.h is included.
4714 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4715 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4716 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4717 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4718 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4719 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4720 when using 'exit' in a test; C99 requires that 'exit' be declared.
4722 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4724 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4725 now prefers 'grep' implementations that accept -e.
4726 (Limitations of Usual Tools): Describe problems of traditional
4727 egrep and fgrep with long input lines, and of traditional grep
4729 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4730 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4731 All callers changed. Append /usr/xpg4/bin to the PATH, for
4733 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4734 the user with complaints about multiple -e options.
4735 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4736 Define it with AC_PROG_GREP.
4737 * configure.ac (AC_PROG_GREP): Add.
4738 * lib/freeze.mk (GREP): New macro.
4740 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4742 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4743 a possible candidate only after all others fail, rather than
4744 consulting it first. This improves backward compatibility by
4745 better reflecting the way shell selection occurred in previous
4746 versions of Autoconf, and should help to avoid triggering latent
4747 problems in other packages, such as the one in Automake where zsh
4748 is not handled robustly:
4749 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4750 Although it is not Autoconf's responsibility to work around
4751 problems in Automake, it nevertheless makes sense to avoid
4752 introducing unnecessary incompatibilites.
4754 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4755 Gary V. Vaughan <gary@gnu.org>
4757 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4758 how deeply nested we are when a suitable tool is found, set the
4759 ac_path_TOOL_found flag.
4760 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4761 nested we are in this macro. Break out of all 3 nested loops if
4762 ac_path_TOOL_found is set.
4764 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4766 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4767 of the _AS_PATH_WALK loop too if GNU flavor is found.
4769 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4771 * doc/autoconf.texi (Limitations of Make): Update documentation
4772 for `$<'. New entry `Long lines', based on a report from Simon
4773 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4774 paragraph about DJGPP, based on a mail from Richard Dawe.
4776 2004-04-20 Paul Eggert <eggert@twinsun.com>
4778 * tests/c.at (C keywords): Don't assume that GCC supports
4779 "restrict" and "inline", as sufficiently-old GCC versions do not
4780 (also, GCC configured to be in pedantic C89 mode does not).
4781 Problem reported by Sumit Pandya in:
4782 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4784 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4785 consider -g to work if it generates warnings when plain compiles
4786 don't. Problem reported by Braden McDaniel in:
4787 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4789 * doc/autoconf.texi (Slashes): New section, to document a problem
4790 reported by Jim Meyering in:
4791 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4793 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4794 linker output files before linking, to work around IRIX 6 linker bug.
4795 Problem reported by Rainer Orth in:
4796 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4798 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4800 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4801 best tool so far counter rely on the tool path variable name to
4802 avoid checks for one tool being affected by the results of running
4803 the length check on a previous tool.
4805 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4806 match expression argument, as different greps have different
4807 regular expression flavours.
4808 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4810 (AC_PROG_EGREP): Pass 'EGREP$'.
4811 (AC_PROG_GREP): Pass 'GREP$'.
4813 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4815 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4816 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4818 2004-03-29 Paul Eggert <eggert@twinsun.com>
4820 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4821 Types, Specific Compiler Characteristics, System Services,
4822 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4823 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4824 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4825 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4827 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

4836 2004-03-28 Paul Eggert <eggert@twinsun.com>
4838 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4839 now defines HAVE_DECL_TZNAME if it is declared, when
4840 HAVE_STRUCT_TM_TM_ZONE is not defined.
4841 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4842 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4845 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4847 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4848 superfluous backslashing of quotes (") in sed expressions;
4849 thanks to Paul Eggert.
4851 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4853 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4854 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4855 H. F. Beebe for the bug report.
4857 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4859 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4860 quoted -cmdline argument in Portland Group compiler (bug
4861 reported by Jeffrey J. Barteet).
4863 2004-03-25 Kevin Ryde <user42@zip.com.au>
4865 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4866 (Run Time): ... here, where it's now mentioned.

4905 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
4906 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
4909 2004-03-03 Paul Eggert <eggert@twinsun.com>
4911 * bin/Makefile.am (edit): Don't use $< in a context where
4912 POSIX doesn't require support for it. Use $@.in instead.
4913 Problem reported by Anthony N. Frasso in
4914 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4915 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

4919 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4920 from the next generation of Libtool.
4921 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4923 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4925 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4926 is not always thread-safe. Report from Nathanael Nerode.
4928 2004-02-18 Paul Eggert <eggert@twinsun.com>
4930 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4931 problem on QNX reported by Stephen Rasku in
4932 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4934 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4935 $(m4sh_m4f_dependencies); this removes a FIXME.
4936 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4937 (MAINTAINERCLEANFILES): Split into pieces,
4938 one per related section. Add $(srcdir)/wrapper.in.
4940 2004-02-09 Paul Eggert <eggert@twinsun.com>
4942 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4943 AC_SUBST provides no portable way to escape literal newlines.
4945 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4946 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4947 Darwin uses -lcrt2.o and there's little point to cataloging all
4948 the system variants. Partial fix reported by Andreas Waechter in:
4949 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

4963 refer to the correct file.
4964 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4965 the behavior of the third argument.
4966 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4967 correctly the behavior of the third argument. Document
4968 what the three macros that AU_DEFUN defines do. Fix
4969 warning message when the third argument includes $0
4970 (reported by Alexandre Duret-Lutz).

4973 Eric Sunshine <sunshine@sunshineco.com>
4974 Paul Eggert <eggert@twinsun.com>
4976 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

4993 use AS_INIT_WITH_SHELL_FN.
4994 * bin/autoconf.in, tests/wrapper.in: Regenerated.

5024 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5025 2003 (except 1997) to the list of copyright years. This undoes
5026 the 2003-05-22 change, which removed the older years from the list.
5027 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

5035 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
5037 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5038 egrep and fgrep respectively if $GREP -E/-F don't work.
5039 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5040 _AC_PROG_GREP, and AC_PROG_SED.

5071 2004-01-26 Paul Eggert <eggert@twinsun.com>
5073 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5074 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5075 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5076 not <inttypes.h>. Problem reported by Tim Mooney in
5077 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5078 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5081 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5082 otherwise "make check" fails because it forbids cmp (I guess
5083 because cmp treats files as binary on DOS-like systems).
5085 * tests/mktests.sh: Update copyright date to 2004, since some tests
5086 have changed in 2004.
5088 2004-01-23 Gary V. Vaughan <gary@gnu.org>
5090 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
5091 non-truncating sed or gsed program in PATH.

5093 * doc/autoconf.texi (Particular Programs): Document it.
5096 2004-01-15 Paul Eggert <eggert@twinsun.com>
5098 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since

5105 * doc/autoconf.texi (Programming in M4sh): Document that
5106 AS_MKDIR_P succeeds if the destination is a symbolic link
5107 to an existing directory.
5108 (Limitations of Usual Tools): Note that mkdir -p might not
5109 succeed on symlinks to directories.
5111 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>

5129 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5130 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5131 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5132 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5133 AC_COMPILE_IFELSE, since we now assume our caller invokes
5134 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5135 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5136 of AC_RUN_IFELSE; this avoids the warning mentioned above.

5142 `"'...'"`, as it's confusing (and I suspect it may not work on
5143 some platforms). The code was incorrect anyway, as it assumed
5144 that \$ evaluated to itself in that context. Reported by

5199 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5200 -c -o might not work. From a suggestion by Kevin Ryde.
5201 (C Compiler, Generating Sources, Limitations

5218 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

5611 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
5612 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5613 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

5618 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5619 directory for AC_CONFIG_COMMANDS' first argument exists.
5620 This makes valid the invocation of _AC_SRCPATH that follows.
5621 Reported by Eric Sunshine.
5622 * doc/autoconf.texi (Configuration Commands): Adjust.
5624 2003-09-26 Akim Demaille <akim@epita.fr>
5626 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5627 Reported by Ralf Corsepius.
5629 2003-09-26 Akim Demaille <akim@epita.fr>
5631 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5633 Actually, use AU_ALIAS.
5636 2003-09-26 Paul Eggert <eggert@twinsun.com>
5638 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
5639 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.

5645 The test suite are sometimes assigning timings incorrectly.
5646 Reported by Henk Krus.
5647 Diagnosed by Nicolas Joly.
5649 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5651 Instead of making AT_help a sequence of assignments to grow
5652 $at_help_all, just make AT_help_all be the growing contents of
5653 $at_help_all, and make a single assignment in...
5655 (at_times_skip): Flip the meaning and rename as...

5658 $at_times_file after use, and check it is present before trying to

5665 * bin/Makefile.am (edit): Handle '@configure_input@'.
5666 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5667 (ifnames): chmod -w.
5668 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5669 executables, not bin/ executables! Otherwise all the magic needed
5670 to find non installed files is turned off. This caused a failure
5671 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5672 as found in its environment (sent by tests/autoreconf): pointing
5673 to bin/autom4te that could not find its files.
5674 * tests/mktests.sh: Force the replacement of generated files, for
5675 the sake of "mv" program that are interactive when overwriting a

5770 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5772 Add support for newer Fortran dialects. The F77 interface is
5773 unchanged, and continues to support Fortran 77. New FC macros
5774 correspond to all the old F77 macros, with output variables FC,
5775 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5776 available dialect, but older dialects can be specified. There are
5777 new macros AC_FC_SRCEXT to set the source extension, and
5778 AC_FC_FREEFORM to accept free-form source files.

5816 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5817 are defaulted by AT_CHECK anyway.
5818 Use AT_CHECK_AUTOM4TE.

5900 ($help): Use Autom4te::ChannelDefs::usage.
5901 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5902 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5904 2003-08-21 Akim Demaille <akim@epita.fr>
5906 First stab at preserving warnings between calls to autom4te,
5907 including when the cache is used.
5909 There are still several issues: (i) there are too many runs of m4
5910 (one for include, one for warnings, and some more), (ii) warnings
5911 spreading on several lines are not handled gracefully, (iii) the
5912 code meant to have the call stack display for errors does not work
5913 (its handling should move from m4 to autom4te).
5915 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5917 (@preselect): Add m4_warn.
5918 ($exit_status): Remove, use $exit_code.
5919 ($help): Use Autom4te::ChannelDefs::usage.
5920 (&handle_m4): No longer define the m4_warnings.
5921 At each run, extract and report the warnings.
5922 Always cache the result, including if the exit status is on
5923 failure, since if nothing changes, we should result in the same
5924 failure, hence we can use the cache.
5925 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5926 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5928 (m4_warn): Redefine as a do-nothing: it is its invocation that
5929 matters, as warnings are now reported via traces.
5930 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5931 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5932 the latter reveals calls to the former.
5936 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5938 2003-08-21 Akim Demaille <akim@epita.fr>
5940 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

5960 * bin/autoscan.in: Adjust.
5962 2003-08-20 Akim Demaille <akim@epita.fr>
5964 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5965 Reported by Alexandre Duret-Lutz.
5967 2003-08-20 Akim Demaille <akim@epita.fr>
5969 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5970 * bin/autom4te: Adjust.
5971 In particular, be Autoconf tools are really silent when properly
5972 working, bind the verbosity of the 'note' channel to $verbose.
5973 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5974 (&xsystem, &contents): Remove, since they are exported by...
5975 * lib/Autom4te/FileUtils.pm: this.

6036 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6037 shorter column three. Add DESCRIPTION to log file content.
6039 2003-08-13 Derek Price <derek@ximbiot.com>
6041 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

6097 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6098 not all of them. This fixes 1. the fact that when testing
6099 Autoconf there are many many config.log, 2. the incorrect use of
6100 top_srcdir to find config.log.
6101 Don't mix the detailed output of failed test with the summary of
6102 failures. Rather, append detailed log afterwards.

6127 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
6128 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
6129 ensuring we add -std1 for full-ANSI.

6195 63 for version mismatches.
6197 2003-05-23 Akim Demaille <akim@epita.fr>
6199 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6200 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6201 the middle of a line).
6202 * lib/m4sugar/m4sugar.m4: Likewise.
6203 Remove useless spaces in comments.

6207 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

6219 Paul Eggert <eggert@twinsun.com>
6221 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6222 Remove `#include <stdlib.h>' from the list; we should never
6223 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6224 resulting namespace pollution would cause other tests to fail.
6225 Configure scripts run with some older versions of g++ and HP's
6226 aCC would fail due to such an #include. Problems reported by
6227 Matthew Mueller in <http://bugs.debian.org/120704> and by
6229 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6230 In the test, use the test declaration before including <stdlib.h>,
6231 as that's closer to how it'll be used.
6233 2003-05-23 Akim Demaille <akim@epita.fr>
6235 * doc/autoconf.texi (Header Portability): ucred.h.
6238 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6240 Overhaul Autotest's logging: generate separate log files
6241 in testsuite.dir/NNN/testsuite.log, and append them to
6242 testsuite.log instead of re-running the test verbosely.
6244 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6245 file descriptor, write 0 to at_status_file instead of setting
6246 at_status=0, initialize some new variables (at_status_file,
6247 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6248 to rerun the tests, instead append the at_group_log to the
6249 at_suite_log when a test fails.
6250 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6251 with the AS_MESSAGE_LOG_FD redirected to stdout.
6252 (AT_CLEANUP): save the output status in $at_status_file
6253 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6255 (AT_CHECK): since tests are run with a redirected stdout,
6256 and used to be re-run in verbose mode, turn some $at_verbose
6257 into echo, and don't redirect the output of testing stdout
6260 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6261 the name of the debugging directory and information about

6381 2003-05-06 Akim Demaille <akim@epita.fr>
6383 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6384 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6385 by aclocal.m4 is changed it might require the importing of another
6386 m4 extension file, i.e., aclocal must be run.
6388 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6389 (&parse_args): Use --force with aclocal if required and supported.

6397 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6398 argument instead of a file name, so that the request file remains
6399 open during the whole autom4te run.
6400 ($icache_file): New.
6401 (&freeze): Lock the $icache_file.
6403 2003-04-29 Derek Price <derek@ximbiot.com>
6405 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6406 seperator with m4_append_uniq(). It doesn't work.
6407 (AT_CLEANUP): Add `;' to end of at_help_all.
6408 (AT_INIT): Allow --keywords to be specified more than once. When

6410 seperators to ensure a complete keyword match. Alter at_prev handling
6411 to support the new --keywords behavior.

6417 entries on one line, for brevity and to make it easier for me to
6418 sort my dir-example file in the Texinfo distribution :).

6620 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6621 compiler says yeah, but preproc says nope, compiler is right.
6622 Conversely, prompt the reader to send a bug report to the
6623 maintainers of the package, not of Autoconf.
6625 2003-02-20 Klee Dienes <kdienes@apple.com>
6627 * bin/autoreconf.in (autoreconf_current_directory): Properly
6628 handle an empty aclocal.m4.
6630 2003-02-20 Akim Demaille <akim@epita.fr>
6632 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
6636 2002-12-23 Paul Eggert <eggert@twinsun.com>
6638 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6639 innocuous variant befor including <limits.h> or <assert.h>. This
6640 works around a bug reported by Albert Chin: HP-UX 11i
6641 (and earlier versions) have a <limits.h> that declares
6642 gettimeofday and many other functions.
6644 2002-12-03 Paul Eggert <eggert@twinsun.com>
6648 * NEWS, configure.ac: Update version.
6650 * doc/fdl.texi: Upgrade to FDL version 1.2.
6652 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6653 nontrivially in main's body, so that f's external declaration is
6654 not optimized away in AIX. This should fix the bug reported by
6656 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6658 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6659 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6660 defined, to support freestanding compilers. This should fix the
6661 bug reported by Momchil Velkov in
6662 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6664 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6665 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
6666 obsolete AC_CHECK_TYPE. The missing empty arg was reported
6667 by Simon Josefsson in
6668 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
6670 * Makefile.maint (www-gnu): New macro.
6671 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6672 the location has moved.
6674 2002-12-02 Martin Frydl <martin@systinet.com>
6676 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6677 \(.*\) match is too long and there is something more to be checked.
6678 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

6696 Update from masters.
6698 2002-11-14 Akim Demaille <akim@epita.fr>
6700 * Makefile.maint: Sync with Bison, i.e.:
6701 (po-check): Scan .l and .y files instead of the
6702 .c and the .h files that they generate. This fixes the bug
6703 reported by Tim Van Holder in:
6704 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6705 Look for N_ as well as for _. Try to avoid matching #define for
6709 2002-11-14 Akim Demaille <akim@epita.fr>
6711 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6712 From Paul Eggert and Albert Chin-A-Young.
6714 2002-11-14 Akim Demaille <akim@epita.fr>
6716 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6717 From Paul Eggert and Albert Chin-A-Young.
6719 2002-11-14 Kevin Ryde <user42@zip.com.au>
6721 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6722 than assigning in main, to avoid HP cc +O3 optimizing it away.
6724 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6726 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6727 option. Process --recheck after parsing all options. Pass -q
6728 option to configure on --recheck.
6729 (AC_OUTPUT): Pass -q from configure to config.status.
6730 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6731 arguments to record.
6732 * doc/autoconf.texi (config.status Invocation): Document
6733 config.status -q option.
6735 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
6737 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
6738 Makefile.in if Makefile.am exists.
6739 (output): Strip `.am' from Makefiles. Don't

6760 Reported by Ezra Peisach.
6762 2002-11-05 Akim Demaille <akim@epita.fr>
6764 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6766 We _have_ to stop using the old compatibility scheme that tried to
6767 avoid useless backslashes because Libtool 1.4.3 contains a
6768 AC_DEFINE([error_t], [int],
6769 [Define to a type to use for \`error_t' if it is not
6770 otherwise available.])
6771 We _have_ to quote the single quote and backslashes with \. The
6772 old compatibility scheme saw that ` was backslashed, and therefore
6773 did not quote the single quote. Hence before this patch, Autoconf
6774 was not compatible with Libtool.
6776 2002-11-04 Paul Eggert <eggert@twinsun.com>
6778 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6819 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6820 Make variable, not a shell variable.
6821 Suggested by Bruno Haible.

7146 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
7147 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
7148 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
7150 Reported months ago by H. Merijn Brand.
7152 2002-10-17 Akim Demaille <akim@epita.fr>
7154 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
7156 2002-10-16 Paul Eggert <eggert@twinsun.com>
7158 * Makefile.maint (wget_files): Remove ansi2knr.c.
7159 (ansi2knr.c-url_prefix): Remove.
7161 2002-10-16 Akim Demaille <akim@epita.fr>
7163 Because of caching, some files that no longer exist and are no
7164 longer required can still cause errors.
7165 Reported by Alexandre Duret-Lutz.
7167 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7168 to frozen files in @ARGV, as @ARGV must remain being a list of
7169 files. Rather, at M4 call sites, use this...
7170 (&files_to_options): New function.
7171 (&freeze): Use &error.
7172 (&up_to_date): If a file that was included according to the cache
7173 is no longer there, then the output is out dated.
7174 (&main): Don't even check whether a file is up to date is anyway
7176 * tests/tools.at (autom4te cache): New.
7178 2002-10-16 Akim Demaille <akim@epita.fr>
7180 * bin/autoconf.as: Kill dead options.
7181 * bin/autoupdate.in (&parse_args): Kill old options.
7182 * bin/autoreconf.in (&parse_args): Remove dead options.
7184 (&autoreconf): Report the directories we enter *and leave*, so
7185 that error messages can be easily located, and use GNU Make
7186 format, so that Emacs' compile mode understands us.
7187 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7188 if some file was changed instead of `print'.
7189 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
7190 (&parse_args): Remove the dead options.
7191 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
7192 autoheader's quiet mode.
7193 (AT_CHECK_AUTOUPDATE): Likewise.
7194 * tests/tools.at (autoupdate): Adjust.
7195 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7197 2002-10-11 Akim Demaille <akim@epita.fr>
7199 No longer use CPP to check for the existing of headers: use CC to
7200 check for compilability.
7202 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
7203 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
7204 (_AC_CHECK_HEADER_NEW): Rename as...
7205 (AC_CHECK_HEADER): this.
7207 * lib/autotest/general.m4 (AT_INIT): Include the failed test
7208 numbers in the Subject suggestion.
7210 2002-10-11 Akim Demaille <akim@epita.fr>
7212 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
7213 Suggest using AC_CHECK_DECLS instead.
7215 2002-10-11 Akim Demaille <akim@epita.fr>
7217 * tests/torture.at (AC_ARG_VAR): Have configure report the value
7220 2002-10-11 Akim Demaille <akim@epita.fr>
7222 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
7223 file name to enable parallel executions.
7224 From Sam Varshavchik.
7226 2002-10-08 Akim Demaille <akim@epita.fr>
7228 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7229 aclocal invocation, as Gettext macros might not be visible to
7231 Instead of blindly running autopoint, scan configure.ac (not the
7232 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7233 Reported by Paul D. Smith.
7235 2002-10-08 Paul Eggert <eggert@twinsun.com>
7237 Work around problems found when POSIXLY_CORRECT=1 is set.
7238 None of this seems to have anything to do with POSIX, really,
7239 but it's how Perl getopt works.
7240 * bin/autom4te.in (parse_args): Configure GetOpt with
7242 * doc/autoconf.texi (Invoking autom4te):
7243 --warning -> --warnings.
7244 * lib/autom4te.in: --warning -> --warnings.
7246 2002-09-28 Akim Demaille <akim@epita.fr>
7248 * doc/autoconf.texi (autom4te.cache): New section.
7250 2002-09-28 Akim Demaille <akim@epita.fr>
7252 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
7253 (Automake-preselections): Update.
7254 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
7256 2002-09-28 Akim Demaille <akim@epita.fr>
7258 * lib/autoscan/autoscan.pre: Move all the remaining rules to...

7260 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7261 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
7263 2002-09-28 Akim Demaille <akim@epita.fr>
7265 * tests/torture.at (Configuring subdirectories): Be robust to
7266 users who use config.site to require for a cache: in this case,
7267 the two last configure runs, using two different sets of
7268 arguments, trigger a legitimate error.
7270 2002-09-28 Akim Demaille <akim@epita.fr>
7272 * tests/m4sh.at (Functions Support, Functions and return Support):
7275 2002-09-28 Akim Demaille <akim@epita.fr>
7277 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
7278 autoheader are Perl programs.

7286 (tm_zone): Move their rules to...
7287 * lib/autoconf/types.m4: here, using AN_ macros.
7288 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7289 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7290 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7291 * lib/autoconf/programs.m4: here.

7300 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
7301 that were listed in the original autoscan.list.
7302 * lib/autoconf/headers.m4: Similarly with headers.
7303 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7304 (.m4.m4f): Don't pass --prepend-include, since that's done by
7305 tests/autom4te itself.
7306 * lib/autoscan/Makefile.am: Include freeze.mk.
7307 (autoscan.list): New target --this file is no longer a source.
7308 (autoscan.pre): New file.
7310 2002-09-28 Akim Demaille <akim@epita.fr>
7312 * bin/autoscan.in (@kinds): Make them singular.
7314 (&init_tables): When --debug, report the list of rules to ease
7315 tracking changes in autoscan.list.
7316 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7318 2002-09-28 Akim Demaille <akim@epita.fr>
7320 * lib/autoscan/functions, lib/autoscan/headers,
7321 * lib/autoscan/identifiers, lib/autoscan/makevars,
7322 * lib/autoscan/programs: Merge into...
7323 * lib/autoscan/autoscan.list: this.
7324 * bin/autoscan.in (&init_tables): Adjust.
7326 2002-09-28 Akim Demaille <akim@epita.fr>
7328 * lib/autoscan/functions, lib/autoscan/headers,
7329 * lib/autoscan/identifiers, lib/autoscan/makevars,
7330 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7331 `functions' line is now prefixed with `function:'.
7332 * bin/autoscan.in (&init_tables): Adjust.
7334 2002-09-28 Akim Demaille <akim@epita.fr>
7336 From now on, autoscan files must always map a macro name to a
7337 word: there is no `default' macro for autoscan.
7339 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7341 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7344 2002-09-28 Akim Demaille <akim@epita.fr>
7346 * bin/autoscan.in (%c_keywords): Remove.
7347 (&used): Keep only track of the words we might be interested in.
7348 (&output_kind): It is no longer needed to look for non active
7351 2002-09-27 Akim Demaille <akim@epita.fr>

7354 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
7355 * lib/autoscan/functions: Adjust.
7356 * doc/autoconf.texi (Particular Functions): Adjust.
7358 2002-09-27 Akim Demaille <akim@epita.fr>
7360 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
7362 Thanks to Bill Moseley and Paul Eggert.
7363 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
7364 the tmpdir must be created.
7365 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
7366 dir be in the build tree, instead of $TMPDIR.
7368 2002-09-27 Akim Demaille <akim@epita.fr>
7370 * bin/autoscan.in: Improve the comments.
7371 (&parse_args): Drop obsolete undocumented options.
7372 (&output_kind): Output warnings.
7373 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
7374 (getwd): Trigger a warning.
7376 2002-09-26 Akim Demaille <akim@epita.fr>
7378 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7379 Reported by Ralf Corsepius.
7380 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7382 2002-09-26 Akim Demaille <akim@epita.fr>
7384 Single suffix rules and seperated dependencies are not portable.
7386 * doc/autoconf.texi (Installation Directory Variables): Update.
7387 (Limitations of Make): Some about `Single Suffix Rules and
7388 Separated Dependencies'.
7389 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7390 (ifnames, autoscan, autom4te): Un-factor into several rules.
7392 2002-09-25 Paul Eggert <eggert@twinsun.com>
7394 * BUGS (Interoperability bugs): New section. Mention libtool
7395 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7397 2002-09-24 Paul Eggert <eggert@twinsun.com>
7399 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7400 make handles suffix-rules differently from GNU make.
7402 * bin/Makefile.am (SUFFIXES, .in): Remove.
7403 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7404 Move the body of the old .in rule here.
7406 2002-09-16 Akim Demaille <akim@epita.fr>
7408 i960 compilers create `b.out' files by default.
7409 Reported by Ralf Corsepius.
7411 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7412 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7414 2002-09-13 Paul Eggert <eggert@twinsun.com>
7416 * doc/autoconf.texi (Particular Headers): Remove obsolete
7417 reference to `struct timezone' in the description of
7420 2002-09-13 Akim Demaille <akim@epita.fr>
7424 * config/config.sub, config/config.guess: Update.
7425 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7426 * Makefile.am: Adjust.
7428 2002-09-13 Akim Demaille <akim@epita.fr>
7430 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7431 reading config.log when the compiler is rejected.
7432 Suggested by Guido Draheim.
7434 2002-09-13 Akim Demaille <akim@epita.fr>
7436 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7437 (chdir_init) might hang when stat'ing mounted directories.
7438 Reported by Vance Shipley.
7440 2002-09-12 Akim Demaille <akim@epita.fr>
7442 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7445 2002-09-12 Akim Demaille <akim@epita.fr>
7447 * doc/autoconf.texi (Defining Symbols): Present two different
7448 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7449 difference between 1 argument calls, and 2-3 argument calls.
7451 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7453 * doc/autoconf.texi: Review grammar and punctuation.
7455 2002-09-11 Paul Eggert <eggert@twinsun.com>
7457 * doc/autoconf.texi: Fix minor formatting, spelling, and
7459 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7460 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7463 2002-09-11 Akim Demaille <akim@epita.fr>
7465 * doc/autoconf.texi (Questions): Rename as...
7467 (Defining Directories): New.
7469 2002-09-09 Akim Demaille <akim@epita.fr>
7471 * doc/autoconf.texi (Making testsuite Scripts): Update.
7472 Suggested by Nishio Futoshi.
7474 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7476 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7477 plain `@' is wanted.
7479 2002-09-09 Akim Demaille <akim@epita.fr>
7481 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7482 `duplicates', since the algorithm was too naive and could keep
7483 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7484 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7485 Reported by Ralf Corsepius.
7486 * tests/torture.at (Configuring subdirectories): Exercise these
7489 2002-09-09 Akim Demaille <akim@epita.fr>
7491 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7492 looking for a replacement file.
7493 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7494 directory is relative.
7495 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7496 directory definition.
7497 Reported by Andreas Schwab and Jim Meyering.
7499 2002-09-06 Akim Demaille <akim@epita.fr>
7501 * doc/autoconf.texi (Setting Output Variables): Clarify what
7502 precious variables are.
7503 Suggested by Pontus Skoeld.
7505 2002-09-05 Akim Demaille <akim@epita.fr>
7507 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7508 (ifnames, autoscan, autom4te): Since we don't only depend on
7509 configure.ac variables (such as VERSION etc.), but also on prefix
7510 and so forth, depend on Makefile, not configure.ac.
7511 Reported by Alexandre Duret-Lutz.
7512 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7514 2002-09-05 Kevin Ryde <user42@zip.com.au>
7516 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7517 doesn't seem to be confined to ia64, just say "some versions".
7519 2002-09-04 Akim Demaille <akim@epita.fr>
7521 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7523 * Makefile.am (maintainer-clean-local): Remove.
7524 (MAINTAINERCLEANFILES): Remove COPYING.
7526 2002-09-03 Paul Eggert <eggert@twinsun.com>
7528 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7529 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7532 2002-09-03 Akim Demaille <akim@epita.fr>
7534 * configure.ac: Bump to 2.53d.
7535 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7536 as of today, on Automake's team suggestion.
7538 2002-09-03 Akim Demaille <akim@epita.fr>
7542 2002-09-02 Akim Demaille <akim@epita.fr>
7544 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7546 * configure.ac: Disable SITE_MACRO_DIR.
7548 2002-09-02 Jim Meyering <meyering@lucent.com>
7550 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7551 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7552 Also, tweak grammar: s/make sure to/be sure to/.
7554 2002-09-02 Paul Eggert <eggert@twinsun.com>
7556 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7557 directory names are generally preferable to physical names.
7559 2002-09-02 Akim Demaille <akim@epita.fr>
7561 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7562 Reported by Raja R. Harinath.
7563 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7564 * bin/autoupdate.in: Use error instead of die.
7566 2002-09-01 Paul Eggert <eggert@twinsun.com>
7568 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7569 ordinary shell concatenation rather than echo+tr+sed command that
7570 runs afoul of a long-line-related sed bug in Solaris 8.
7572 * bin/autoheader.in (parse_args): --warning -> --warnings.
7574 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7575 stdout, as traditional "ls" does.
7576 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7577 _AC_COMPILER_EXEEXT_O): Likewise.
7578 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7580 * bin/autoconf.as: Add --prepend-include option. This patch was
7581 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7582 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7584 * bin/autoconf.in, configure: Regenerate.
7586 * doc/autoconf.texi (Special Shell Variables): Mention
7587 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7589 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7590 MAILPATH and set PS1, PS2, PS4 to default values, to work
7591 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7592 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7593 the Autoconf documentation specifies; fall back to "unset" only if
7594 this fails. Use a shell for-loop for this rather than an m4 loop,
7595 to shorten the output script.
7597 2002-08-30 Paul Eggert <eggert@twinsun.com>
7599 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7600 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7601 for the CDPATH problem. Document PWD.
7602 (Limitations of Builtins): Document the problem that "cd $foo" and
7603 "ls $foo" may refer to different directories in shells conforming
7604 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7605 example, since the old example is now out of date.
7607 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7608 FOO" and "ls FOO" talk about different directories; this catches
7609 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7612 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7613 of rolling our own unset.
7614 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7615 in practice we needn't worry about CDPATH if unset doesn't work.
7617 * Makefile.in, aclocal.m4, bin/Makefile.in,
7618 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7619 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7620 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7621 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7622 tests/Makefile.in: Regenerate with Automake 1.6.3.
7624 * config/config.guess, config/config.sub, config/mkinstalldirs:
7627 * configure: Regenerate with self.
7629 2002-08-30 Kevin Ryde <user42@zip.com.au>
7631 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7634 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7636 * bin/autom4te.in (Request::load): Correctly test for "do" read
7639 2002-08-29 Akim Demaille <akim@epita.fr>
7641 * lib/Autom4te/General.pm (&xqx): New.
7642 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7643 hand, which is not portable.
7645 * bin/autom4te.in: Use them.
7646 Use &error instead of die.
7647 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7650 2002-08-17 Paul Eggert <eggert@twinsun.com>
7652 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the

7970 This improves on an earlier suggestion by H. Peter Anvin.
7972 2002-05-16 Paul Eggert <eggert@twinsun.com>
7974 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7975 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7976 Both macros now accept an optional source-dir arg.
7977 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7979 * NEWS: Document this.
7980 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7982 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7983 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,

7993 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7994 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7995 and it causes a 'test' syntax error if it fails.
7996 Bug reported by Stephen Gildea.
7998 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7999 If prototypes are supported, use them to check this at compile-time,
8000 instead of trying to check it at run-time. If we must do a run-time
8001 check, assume that setvbuf is standard when cross-compiling, as
8002 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8003 Bug reported by Paul D. Smith.
8005 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8006 argument specifying location of getloadavg.c. This removes a
8007 FIXME. This idea was taken from Jim Meyering's implementation in
8009 * doc/autoconf.texi (Particular Functions): Document this.
8010 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8011 that's what the code does; this fixes a bug reported by

8016 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8017 autopoint instead of gettextize.
8018 ($uses_alocal): Rename as...
8019 ($uses_aclocal): this.
8020 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8021 Suggested by Bruno Haible.

8027 2002-04-29 Paul Eggert <eggert@twinsun.com>
8029 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8030 files to be 1 second older; just set them to be the same time.
8031 Also, sleep 1 second after the first aclocal, to work around
8032 problems with sub-second time stamps on the input files.
8034 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8036 * doc/autoconf.texi: Mention "set -e -x" lossage

8045 2002-04-29 Akim Demaille <akim@epita.fr>
8047 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8048 of lack of $LINENO support, then the test will compare the $LINENO
8049 in testsuite vs. the lineno in the test file. This is wrong, of
8051 Be sure to protect it.
8052 Reported by Patrick Welche.
8054 2002-04-25 Akim Demaille <akim@epita.fr>
8056 * doc/autoconf.texi (Obsolete Macros): Typo.
8057 Reported by Vladimir Volovich.
8059 2002-04-25 Akim Demaille <akim@epita.fr>
8061 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8062 than some of the input files, hence, on the second run of aclocal,
8063 if some of its input are younger, make them older.
8064 Suggested by Paul Eggert.
8066 2002-04-25 Akim Demaille <akim@epita.fr>
8068 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

8074 and ac_subst_vars be sh variables containing the list of
8075 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8077 (_AC_INIT_PREPARE): Use them to log them.
8078 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8079 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the

8088 config.h.in that was to be created.
8090 2002-04-23 Akim Demaille <akim@epita.fr>

8168 Use Zsh alias to work around problem.
8169 * tests/atgeneral.m4 (AT_INIT): Likewise.
8171 * tests/c.at: We can't have zero arguments, so remove workaround
8172 that is not portable to Zsh.
8174 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8176 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8177 from aclocal.m4 too.
8179 2002-04-12 Akim Demaille <akim@epita.fr>
8181 * tests/wrappl.as: New, M4sh precursor of wrappl.in.

8194 (_AS_PREPARE): this new macro.

8199 Adjust Autoconf and Autotest.
8201 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8202 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8203 * lib/autotest/general.m4 (AT_INIT): Likewise.
8204 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8205 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8208 Use this M4sh to generate Autoconf's shell scripts.
8210 * tests/wrapsh.as: New, precursor of wrapsh.in.
8211 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8212 on Autotest and M4sh.

8221 with indented comments in rules.

8230 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
8231 (Portable Shell): Cross reference to Systemology.
8233 2002-04-05 Akim Demaille <akim@epita.fr>
8235 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8236 directories when descending in a SUBDIRS.
8237 Reported by Ezra Peisach.
8239 2002-04-04 Andreas Schwab <schwab@suse.de>
8241 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8242 contains no literal separators.
8244 2002-04-03 Akim Demaille <akim@epita.fr>
8246 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8247 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8248 Use dnl, not the KILL diversion.
8250 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8251 (AC_CONFIG_LINKS): here.
8253 Don't use the KILL diversion, as it kills spurious output, which
8254 results in failures being hidden.
8255 Use m4_defn where appropriate.
8256 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8257 after the second argument.
8259 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8260 syntax, as it is provided by M4sugar.

8278 Fixes Debian #138666.
8280 2002-04-02 Peter Eisentraut <peter_e@gmx.net>

8285 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
8286 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
8287 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
8289 (AC_C_INLINE): Same.

8298 _AS_MKDIR_P_PREPARE.
8300 2002-03-28 Kevin Ryde <user42@zip.com.au>
8302 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8303 to avoid versions of HP C which don't allow that.
8305 2002-03-27 Paul Eggert <eggert@twinsun.com>
8307 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8308 (AS_SHELL_SANITIZE): Invoke it.
8309 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

8313 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
8315 2002-03-26 Akim Demaille <akim@epita.fr>
8317 * doc/autoconf.texi (Introduction): The GNATS base moved.
8319 2002-03-25 Paul Eggert <eggert@twinsun.com>
8321 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8322 as POSIX requires, as it doesn't work with Zsh.
8323 * doc/autoconf.texi (Assignments): Document the problem.
8325 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8327 * doc/autoconf.texi (Limitations of Make): Mention more issue
8328 about VPATH, overriding of macros in sub-makes, and handling of
8331 2002-03-21 Paul Eggert <eggert@twinsun.com>
8333 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8334 problem with here-document buffer boundaries.
8336 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8337 when reinvoking the shell, to work around problems with installers
8338 who put strange things like "cd" commands in their environments.
8340 2002-03-19 Akim Demaille <akim@epita.fr>
8342 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8345 2002-03-19 Akim Demaille <akim@epita.fr>
8347 * bin/autoscan.in (scan_file): Specify the location in `&used'
8351 2002-03-19 Akim Demaille <akim@epita.fr>

8354 From Nishio Futoshi.
8356 2002-03-19 Akim Demaille <akim@epita.fr>
8358 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

8362 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8363 (Limitations of Usual Tools): Add mkdir section.
8365 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8366 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8367 back on AS_DIRNAME to compute prefixes otherwise; this is
8368 roughly what mkinstalldirs does. That way, we need not have
8369 our own filename disassembler. The old disassembler did not
8370 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8372 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8373 Create at_test_all by a series of assignments,
8374 not by a single assignment of a long string. The latter causes ksh
8375 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8376 presumably because of a buffer overrun.
8378 2002-03-14 Paul Eggert <eggert@twinsun.com>
8380 * lib/autotest/general.m4 (at_times_skip):
8381 Renamed from at_times. Now a boolean.
8382 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8383 says 'times: not found'.
8385 2002-03-14 Akim Demaille <akim@epita.fr>
8387 * bin/autoreconf.in (&study_gettextize): New.
8388 (&autoreconf): Handle newest gettextize.
8389 Rerun aclocal if needed.
8390 Suggested by Andreas Schwab.
8392 2002-03-13 Akim Demaille <akim@epita.fr>

8412 2002-03-11 Andreas Schwab <schwab@suse.de>

8415 does not do it if --with-lispdir is given.

8421 2002-03-08 Akim Demaille <akim@epita.fr>
8423 * doc/autoconf.texi (Subdirectories): Clarify that the
8424 subdirectory should exist.
8426 2002-03-08 Akim Demaille <akim@epita.fr>
8428 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8430 2002-03-08 Akim Demaille <akim@epita.fr>
8432 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8433 aliases the actual variables, and modifications of the former
8436 2002-03-08 Akim Demaille <akim@epita.fr>
8438 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8439 because of C-c: have m4 output in tmp files, then mv them.
8441 2002-03-08 Akim Demaille <akim@epita.fr>
8443 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8444 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8445 * bin/ifnames.in: Copyright update.

8460 2002-03-04 Akim Demaille <akim@epita.fr>
8462 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8463 * lib/autoconf/general.m4 (AC_INIT): More informative error
8466 2002-03-04 Akim Demaille <akim@epita.fr>
8468 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8471 2002-03-04 Akim Demaille <akim@epita.fr>
8473 * doc/autoconf.texi (Transforming Names): Equality between target
8474 and host is irrelevant.
8475 (Specifying Names, Canonicalizing): Remove all references to the
8476 backward compatibility hooks. Rather, collect them all into...
8477 (Hosts and Cross-Compilation): this new section.
8478 * doc/install.texi (System Type): Ditto.
8479 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8480 that `--host' implies cross-compilation.
8482 2002-03-04 Akim Demaille <akim@epita.fr>
8484 * doc/autoconf.texi (Evaluation Macros): New.
8485 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8487 (_m4_foreach): Define the variant with immediate evaluation so
8488 that it contains exactly the items, not an expression which
8489 evaluation is the current item.
8490 (m4_re_string, m4_re_word): Don't over quote them.
8492 2002-03-04 Akim Demaille <akim@epita.fr>
8494 Instead of having stacking `shift's evaluated at the end, let
8495 `foreach' loops immediately evaluate them.
8497 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8498 $*. This is the n-th time I change my mind, but hopefully this is
8501 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8503 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8504 it was only a hack for m4_text_wrap.
8505 (m4_car2): Remove, replaced by...
8507 (_m4_foreach): Adjust.
8508 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8509 m4_bpatsubst for clarification.
8511 2002-03-04 Akim Demaille <akim@epita.fr>
8513 * doc/autoconf.texi (Changequote is Evil): New.
8515 2002-03-03 Kevin Ryde <user42@zip.com.au>
8517 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
8518 on old systems like SunOS.

8558 2002-02-07 Akim Demaille <akim@epita.fr>
8560 Fix Autoconf PR/207:
8561 AC_PREFIX_PROGRAM fails with dashed program names
8563 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8564 variable when looking for the prefix program.
8565 Now it also works for shell variables.
8567 2002-02-07 Akim Demaille <akim@epita.fr>

8575 case/esac, some shells don't support it.
8576 Reported by Zack Weinberg.
8577 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
8579 2002-02-06 Akim Demaille <akim@epita.fr>
8581 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8582 sure not to introduce newlines in at_groups.
8583 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8585 2002-02-06 Akim Demaille <akim@epita.fr>
8587 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8590 2002-02-05 Paul Eggert <eggert@twinsun.com>

8596 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8597 cross-compilers, too. This undoes some of the most recent change
8600 2002-02-05 Akim Demaille <akim@epita.fr>
8602 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8603 to make sure they are up to date when `check' is run.
8605 2002-02-05 Akim Demaille <akim@epita.fr>
8607 * doc/autoconf.texi (Making testsuite Scripts): Document

8616 Implement `autom4te --freeze'.

8619 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,

8622 2002-02-05 Akim Demaille <akim@epita.fr>
8624 * bin/autom4te.in (&parse_args): Implement `frozen files are
8625 optional are the sum of the previous files on the command line'.
8626 Also, pass `--reload-state=' on them, so...
8628 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8629 (M4sh): Rely on M4sugar.
8630 (Autotest, M4sh, M4sugar): Use frozen files.
8632 2002-01-31 Akim Demaille <akim@epita.fr>
8634 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

8637 2002-01-30 Akim Demaille <akim@epita.fr>
8639 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8640 alphanumeric to `-' instead of `_'.
8642 2002-01-30 Akim Demaille <akim@epita.fr>
8644 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8645 for plain code, the other for cross-compilation code. The latter
8646 is now run with GCC only.
8647 * doc/autoconf.texi (Compilers and Preprocessors): New.

8654 change AC_INIT default values.
8656 2002-01-29 Akim Demaille <akim@epita.fr>
8658 * tests/torture.at (Configuring subdirectories): Use configure.in,
8659 so that aclocal 1.4 works.
8660 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8662 2002-01-28 Akim Demaille <akim@epita.fr>
8664 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8667 2002-01-28 Akim Demaille <akim@epita.fr>
8669 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8670 AUTOTEST_PATH *after* it was set.
8671 Don't put `.' in the PATH: the user should be precise and `./' if
8672 needed. In addition, given that the test suite does some `cd', if
8673 `.' is in the path, the `tested programs' sections will report
8674 programs found in the test suite's directory, while during the
8675 tests (performed in their own directory), these programs are no
8676 longer visible. In other words, the results is confusing and
8678 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

8691 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8692 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be

8741 2002-01-06 Akim Demaille <akim@epita.fr>
8743 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8744 package.m4, since is really depends upon configure.ac, not
8746 * doc/autoconf.texi (testsuite Scripts): Adjust.
8747 * tests/Makefile.am (package.m4): New.
8748 EXTRA_DIST it since its a source.
8750 2002-01-06 Akim Demaille <akim@epita.fr>

8753 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8754 and PACKAGE_BUGREPORT from here...
8755 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the

8782 2001-12-14 Akim Demaille <akim@epita.fr>
8784 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8785 trailing files, don't apply `-rf' to files which might not be
8786 created by configure (core, core.*, and *.core), but just `rm -f'.
8787 Suggested by Jonathan Kamens.
8789 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8791 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8793 2001-12-14 Akim Demaille <akim@epita.fr>
8795 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8797 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

8801 abs_srcdir, top_srcpath to abs_top_srcdir.
8802 (_AC_OUTPUT_FILES): Adjust.
8803 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,

8807 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8809 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8810 C/Fortran linking on HP/UX, by extracting the Fortran library
8811 search path from the LPATH line in the $F77 -v output.
8813 2001-12-12 Kevin Ryde <user42@zip.com.au>
8815 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the

8818 2001-11-26 Akim Demaille <akim@epita.fr>
8820 * bin/autoscan.in (%c_keywords): Build it at top level.
8821 Map to 1 in order to simplify its uses.

8825 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8826 Remove $filepath, useless.
8827 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8828 variables, they are really part of the tokens.
8829 Split the input line on spaces and then look for tokens.
8830 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8831 because of `lex$U.$(OBJEXT)'.
8832 (&scan_files): Use "@list" instead of join.
8833 * doc/Makefile.am (CLEANFILES): Add *.fns.
8835 2001-11-26 Akim Demaille <akim@epita.fr>
8837 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8838 Remove, replaced by...
8839 * tests/wrappl.in: Be common for all the Perl executables.
8840 In particular autoscan and autoheader want -I.
8841 * configure.ac: Adjust.
8842 * lib/autoscan/headers: errno.h is portable.
8844 2001-11-26 Akim Demaille <akim@epita.fr>
8846 * bin/autoscan.in (used): New.
8849 2001-11-26 Akim Demaille <akim@epita.fr>

8865 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8866 (testsuite Scripts): Be one of its subsection.
8867 (Autotest Logs): New.
8869 2001-11-26 Akim Demaille <akim@epita.fr>
8871 Test groups are now run two directories deeper.
8873 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8874 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8876 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8877 top_srcdir, builddir and top_builddir.
8878 Use `at_*dir' relatively to the directory containing the
8879 suite, use `*dir' when relatively to the current group dir.
8881 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8883 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8884 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8885 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8888 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8890 * doc/autoconf.texi (Using System Type): Add an example of `case
8891 $host' usage so people quit using `case $target' everywhere.
8893 2001-11-22 Akim Demaille <akim@epita.fr>
8895 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8896 spotted by Jim Meyering.
8898 2001-11-16 Paul Eggert <eggert@twinsun.com>
8900 This patch implements a `long double' suggestion by Oliver Kiddle.
8902 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8903 static, to catch errors if the value isn't known at compile-time
8904 and the compiler supports dynamic arrays. Change its name from
8905 `_array_' to `test_array' to avoid potential name clashes.
8906 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8907 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8908 better than double. Catch a bug in GCC 2.95.2 x86.
8909 * doc/autoconf.texi (C Compiler): Document the above.
8912 2001-11-13 Akim Demaille <akim@epita.fr>
8914 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8916 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8918 2001-11-13 Akim Demaille <akim@epita.fr>
8920 * lib/autotest/general.m4 (AT_INIT): After having run the test
8921 group, go back to the initial directory, not to at_suite_dir.
8923 2001-11-13 Akim Demaille <akim@epita.fr>
8925 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8926 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8927 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8929 (AT_CHECK_CONFIGURE): Use absolute paths.
8930 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8931 The problem is still the old one: there is no means in M4 (that I
8932 know about) to create a defining macro, because there is no means
8933 to create `$1' etc., therefore, the defining macro ``swallows''
8934 all the arguments meant to the defined macro.
8936 2001-11-13 Akim Demaille <akim@epita.fr>
8938 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8939 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8941 * tests/aclocal.m4: Remove, as it is no longer used.
8943 2001-11-13 Akim Demaille <akim@epita.fr>
8945 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8946 variable names when referring to a single test group, or to
8947 `suite' when referring to the whole test suite.
8948 `at_last_test' is removed: m4 compute at_format itself.
8949 (at_stdout, at_stder1, at_stderr): New variables.
8950 (AT_CHECK): Use them.
8952 2001-11-13 Akim Demaille <akim@epita.fr>
8954 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8956 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8957 Do it as soon as a test fails, don't wait till the end of the test
8959 Don't remove $as_me.[0-9]*, since these files no longer exist.
8961 2001-11-13 Akim Demaille <akim@epita.fr>
8963 * tests/tools.at: Use absolute paths, since we are no longer run
8966 2001-11-13 Akim Demaille <akim@epita.fr>
8968 Now that tests are running in their own private dir, there is no
8969 need to list the files to remove at the end of tests groups.
8971 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8972 (AT_data_files, at_data_files): Remove.
8973 (AT_CLEANUP, AT_DATA): Simplify.
8975 Remove the group dir if !debug && !failed.
8976 * tests/atspecific.m4: Adjust.
8978 2001-11-13 Akim Demaille <akim@epita.fr>
8980 Start a new layout for Autotest: `testsuite' creates
8981 `testsuite.dir' in which the at-check-line etc. files are to be
8982 found, and `testsuite.dir/003' where the test group 3 is run.
8984 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8985 at_check_line_file, at_format, at_test_normalized, at_group_dir
8987 Create the directories.
8988 Use absolute paths for at- files.
8991 2001-11-11 Michael Matz <matz@kde.org>
8993 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8995 (m4_car): Properly quote arguments.
8997 2001-11-13 Akim Demaille <akim@epita.fr>
8999 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9000 with stricter rules on LIBOBJS.
9002 2001-11-12 Paul Eggert <eggert@twinsun.com>
9004 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9005 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9008 2001-11-12 Akim Demaille <akim@epita.fr>
9010 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9012 2001-11-12 Akim Demaille <akim@epita.fr>
9014 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9015 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9016 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9017 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9018 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9019 specify to what the macro should be defined (typically to 1).
9021 2001-11-12 Akim Demaille <akim@epita.fr>
9023 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9026 2001-11-12 Akim Demaille <akim@epita.fr>
9028 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9029 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9030 definition used by Automake where LEX is +/- "${missing} lex" and
9031 `missing' itself contains variables.
9033 2001-11-12 Akim Demaille <akim@epita.fr>
9035 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9036 Now that M4sh pushes BODY, the comments were output at the end of
9039 2001-11-08 Akim Demaille <akim@epita.fr>
9041 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9042 that we can trace macros from aclocal.m4.
9043 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9044 obsoleted, and redirect to the former anyway.
9045 Reported by Ralf Corsepius.
9047 2001-11-08 Akim Demaille <akim@epita.fr>
9049 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9050 processed only if present.
9051 * tests/torture.at (Configuring subdirectories): Use autoreconf
9052 instead of successive calls to autoconf.
9053 Add a nonexistent subdirectory to exercise the patch above.
9054 Reported by Ralf Corsepius.
9056 2001-11-08 Kevin Ryde <user42@zip.com.au>
9058 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9059 doesn't accept .S files.
9061 2001-11-07 Akim Demaille <akim@epita.fr>
9063 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9064 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9065 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
9066 * bin/autom4te.in (warn_forbidden): New.
9067 (handle_output): Use it.
9068 Read m4_pattern_forbid with messages.
9070 2001-11-05 Akim Demaille <akim@epita.fr>
9072 * bin/autom4te.in (--normalize): Remove.
9073 * lib/autom4te.in: Adjust.
9075 2001-11-05 Akim Demaille <akim@epita.fr>
9077 * tests/Makefile.am (testsuite): Rename this target as...
9078 ($(TESTSUITE)): this.
9081 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9083 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9084 the --prefix option, also remove it's argument.
9086 2001-11-05 Akim Demaille <akim@epita.fr>
9088 * doc/autoconf.texi (testsuite Invocation): Update.
9089 (Writing testsuite.at): Update.
9091 2001-11-03 Akim Demaille <akim@epita.fr>
9093 * doc/autoconf.texi: s/@code/@command/ where appropriate.
9095 2001-11-03 Akim Demaille <akim@epita.fr>
9097 * lib/Autom4te/General.pm: (&catfile, &canonfile)
9098 (&file_name_is_absolute): New, wrappers around routines from
9100 Use and export them.
9101 (&find_configure_ac): Optionally take a directory where to look at.
9102 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
9104 Default @ARGV to `.', not find_configure_ac.
9105 (&autoreconf): Argument is a directory.
9106 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
9107 * doc/autoconf.texi (autoreconf Invocation): Update.
9109 2001-11-03 Akim Demaille <akim@epita.fr>
9111 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9112 (@export_forward_subs): New.
9113 Add basename, dirname, and fileparse.
9115 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9116 Don't look for aclocal flags if we already know aclocal is not
9118 Move aclocal.m4t only if it exists.
9119 Reported by Ezra Peisach.
9121 2001-11-03 Akim Demaille <akim@epita.fr>
9123 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9124 passed on command line, defaulting to ./configure.ac if present.
9125 (&maybe_autoreconf, File::Find): Remove, unused.
9126 (&autoreconf): If autoconf is not used, don't try to trace.
9128 2001-11-02 Akim Demaille <akim@epita.fr>
9130 * configure.ac: Bump to 2.52g.
9132 2001-11-02 Akim Demaille <akim@epita.fr>
9136 2001-11-02 Akim Demaille <akim@epita.fr>
9138 * config/config.guess, config/config.sub, doc/standards.texi:
9139 * config/lispdir.m4: Update from masters.
9140 * configure.ac: Bump to 2.52f.
9142 2001-11-02 Akim Demaille <akim@epita.fr>
9144 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9145 Don't run aclocal when aclocal.m4 is not from aclocal.
9147 Don't run libtoolize and gettextize if --install is not given.
9149 2001-11-01 Paul Eggert <eggert@twinsun.com>
9151 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9152 be invoked before _AS_LINENO_PREPARE.
9153 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9154 than character ranges.
9156 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9157 invoking AS_BASENAME. Set the locale variables to 'C' if
9158 possible, as POSIX requires this to get the traditional
9160 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9162 2001-10-31 Paul Eggert <eggert@twinsun.com>
9164 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9165 with {}, as that triggers a bug in Bash 2.05.
9167 (_AS_LINENO_PREPARE): Use Sed rather than
9168 Awk. Fix the sed prepass to work even if there are multiple
9169 instances of $LINENO on the same line. Do not substitute for
9170 other variables like $LINENOT. Do not check file dates; such a
9171 check is unreliable on sufficiently fast machines, and removing
9172 the check makes the code simpler and more reliable. Check for
9173 output and chmod failures.
9175 * doc/autoconf.texi (Special Shell Variables): Document

9185 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9186 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9187 provided, while it is optional.
9188 * configure.ac: Adjust.
9190 2001-10-26 Paul Eggert <eggert@twinsun.com>
9192 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9193 lib/Autom4te/Struct.pm:
9194 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9197 * doc/autoconf.texi (Special Shell Variables): Document some
9198 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9200 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9201 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9202 eval $LINENO is not portable in practice.
9204 2001-10-24 Akim Demaille <akim@epita.fr>
9206 * lib/Autom4te/General.pm (backname): New.

9221 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,

9225 Assign to a char* var, to catch strerror_r that returns int*.

9718 * doc/autoconf.texi (File System Conventions): Clarify the use of
9720 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9721 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9722 be used instead of ':'.

9726 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9729 arguments. Fixed a typo.
9731 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9733 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

9749 CR issues on DOSish systems).
9751 2001-09-19 Akim Demaille <akim@epita.fr>
9753 * lib/autotest/general.m4: Englishoes.

9758 * doc/autoconf.texi (Common Shell Constructs): New node,
9759 documenting AS_DIRNAME.
9760 (Limitations of Usual Tools): Refer to it when discussing dirname.
9761 Also, update discussion of POSIX standard to reflect latest draft.
9763 * lib/autoconf/c.m4:
9764 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9766 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9767 Do not pass a first argument with leading '-'
9768 to expr, by parenthesizing initial integers that might be negative.
9770 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9771 now merely checks whether it is an error to pass an argument
9774 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9775 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9776 whether it is a (compile-time) error to pass an argument to
9777 getpgrp. This simpler test supports the revised documentation,
9778 and is all that AC_FUNC_GETPGRP's users really need.

9794 Add test for AS_BASENAME.
9795 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9796 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9797 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9798 * tests/base.at: Fixed the expected responses. The old ones were
9800 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9801 the documentation claims it should (and how it behaved in 2.13).
9803 2001-09-18 Akim Demaille <akim@epita.fr>
9805 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9806 the AC_CONFIG_COMMANDS invocation.
9807 This also solves the name clash problems.
9808 Don't set the package's ID.

9810 No longer to be shipped.
9811 (version.in): Remove.

9813 * lib/autoconf/status.m4: Adjust.
9814 Use `m4_PACKAGE_STRING'.
9815 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9816 the only optional argument is the name of the test suite.
9817 Expect `package.m4' to define the package signature.
9818 * lib/autom4te.in (Autotest): Add `package.m4?'.
9819 * tests/Makefile.am (package.m4): New.

9839 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9840 Always include <stdio.h> and <stdlib.h>. Evaluate
9841 the expression in an extra function before these includes. Call
9842 fprintf "%d" only after ensuring the argument is of type 'int'.
9843 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9845 2001-09-17 Paul Eggert <eggert@twinsun.com>
9847 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9848 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9849 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9850 when they don't exist.
9852 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9853 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9856 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9857 version with the version used by fileutils 4.1, except use
9858 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

9903 * lib/autotest/general.m4 (AT_INIT): Create and remove
9904 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9905 test suites can cohabit.
9907 2001-09-13 Akim Demaille <akim@epita.fr>
9909 * tests/mktests.sh: Don't output banners for empty test files.
9911 2001-09-13 Akim Demaille <akim@epita.fr>

10018 the maintainer is dumb enough to do that...
10020 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10021 excellence in M4 quotation: consider `__file__' is active.

10117 Use directly autom4te, not autoconf.

10184 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10186 Use -e, not -f, since /dev/null for instance is OK.
10187 (&parse_args): Adjust.
10188 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.

10198 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

10200 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10201 find the executables for it.

10203 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10205 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10206 indeed related to running the test suite, while passing
10207 --autoconf-dir and others is related to running non installed
10208 Autoconf executables. So don't do that, leave it to...
10209 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10210 * tests/autoscan: New.
10211 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

10230 2001-08-29 Akim Demaille <akim@epita.fr>

10700 2001-08-15 Akim Demaille <akim@epita.fr>
10702 * bin/autom4te.in (@m4_warning): New.
10703 (&handle_m4): Use it.
10704 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

10776 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10777 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10778 * doc/autoconf.texi (C Compiler Characteristics): Update

10784 magic values from an object file when cross-compiling.
10785 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10787 2001-08-10 Akim Demaille <akim@epita.fr>
10789 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10791 Suggested by Russ Allbery.
10793 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10795 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10796 current $prefix to the sub-configures.
10798 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10800 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10801 extension (needed on BeOS). Reported by Guido van Rossum.
10803 2001-08-09 Akim Demaille <akim@epita.fr>
10805 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10807 2001-08-07 Akim Demaille <akim@epita.fr>
10809 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10811 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10812 No need to remove the files before and after the each test, before
10813 each test and at the end of the suite is enough.
10814 Display only the children `times', not the shell's.
10815 If the test failed or was skipped, at-times is not available.
10817 2001-08-07 Akim Demaille <akim@epita.fr>
10819 Always produce testsuite.log, including when there are no
10820 failures. This helps getting information on skipped tests, and
10821 duration of the tests. Err, implement the latter btw.
10823 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10824 Dump information on the first run of each test.
10825 (AT_CLEANUP): Create `at-times' containing the duration of the
10828 2001-08-07 Akim Demaille <akim@epita.fr>
10830 The use of `dumpstat' revealed that `len' was used although it
10831 should not. m4_text_wrap was using it, but in the Autoconf world
10832 where it is legal. Hence (i) test M4sh in its own world, not
10833 Autoconf's, and (ii), ahem, fix the bug :)
10835 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10836 does not like `' instead of [].
10837 (AT_INIT): Forbid `^_?AT_'.
10838 And don't output such tokens.
10839 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10840 `script.as', and `autom4te.cache'.
10841 Remove `empty' and `macro' which are no longer used.
10842 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10843 * tests/m4sugar.at: Use it.
10844 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10846 2001-08-07 Akim Demaille <akim@epita.fr>
10848 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10850 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10852 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10854 2001-08-04 Akim Demaille <akim@epita.fr>
10856 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10857 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10859 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10860 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10861 (AC_F77_MAIN): Likewise.
10863 2001-08-04 Akim Demaille <akim@epita.fr>
10865 Don't rely on M4sugar outputting the patterns in files, since we
10866 might process the output _without_ running m4, hence without these
10869 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10870 * bin/autom4te.in (@Request::includes): Remove, unused.
10871 (@Request::source): Rename as...
10872 (@Request::input): this.
10873 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10874 (&handle_output): Fetch the patterns from the traces.
10875 `$forbidden' and `$allowed' are constant: use m//o.
10876 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10877 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10879 2001-08-04 Akim Demaille <akim@epita.fr>
10881 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10882 autoconf', i.e., in addition to caching traces, cache the output.
10884 * bin/autom4te.in (Request::cache): Rename as...
10885 (Request::id): this.
10886 ($cache, $icache, $tcache, $ocache): New.
10887 (&handle_m4): Save M4 output in the cache instead of $tmp.
10888 (&handle_output): Adjust.
10889 (&up_to_date_p): Check that the output cache is up to date too.
10890 (top level): Run `&handle_m4' iff force or the cache is invalid.
10891 Run `&handle_output' if the output cache is more recent.
10893 2001-08-04 Akim Demaille <akim@epita.fr>
10895 * bin/autom4te.in ($force): New.
10896 (&parse_args, &print_usage): -f, --force is a new option.
10897 (&handle_output): CPP directives might have spaces after `#'.
10898 (&parse_args): The first file only can be frozen.
10900 2001-08-04 Akim Demaille <akim@epita.fr>
10902 Don't let autom4te compute the `include' traces several times:
10903 first check that the trace cache file is up to date, and then
10904 compare its timestamp with that of the output.
10906 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10907 the preamble. Don't require 5.005 as Autom4te::General does it,
10908 and better yet (use `use', not `require'!).
10909 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10910 Class::Struct as Autom4te::Struct.
10911 * lib/Autom4te/General.pm (File::stat): Use it.
10912 (&mtime): New, export it.
10913 * bin/autom4te.in: Use it.
10914 Declare `$req' is invalid if it is outdated.
10915 Don't declare it valid before saving it if something went wrong.
10917 2001-08-04 Akim Demaille <akim@epita.fr>
10919 Autom4te shall not encode Autoconf data, and preselecting traces
10920 must be proposed to the users.
10922 * bin/autom4te.in (@required_trace): Remove.
10924 (&parse_args, &print_usage): -p, --preselect is a new option.
10925 (&up_to_date_p): Adjust.
10926 * bin/autoconf.in: Preselect some Autoconf macros.
10928 2001-08-04 Akim Demaille <akim@epita.fr>
10930 * tests/tools.at (autoconf --trace: user macros): Check traces on
10931 macros invoked without arguments, and macros invoked with multiple

10939 2001-08-03 Akim Demaille <akim@epita.fr>
10941 * bin/autoconf.in ($@): Work around the usual sh bug.
10944 2001-08-03 Akim Demaille <akim@epita.fr>
10946 Clean up the handling of the M4 builtins tracing exception.
10948 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10950 (@m4_builtins): Rename as...
10951 (@m4_builtin): this.
10952 (%m4_builtin_alternate_name): New.
10953 (&parse_args): Complete the trace requests with alternate names.
10954 (&handle_traces): Hence no longer do it here.
10955 (&trace_requests): Remove, unused.

10959 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10960 m4_if, and m4_wrap.
10962 2001-08-03 Akim Demaille <akim@epita.fr>
10964 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10965 (m4_divert_pop): Dump the whole diversion stack when a diversion
10967 * bin/autom4te.in (&handle_output): Remember of the first
10968 occurrence of a possibly undefined macro, not the last.
10969 Complain about the possibly undefined macros in the same order as
10970 the appear in the output.
10971 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
10972 * tests/tools.at (autoconf: forbidden tokens, basic)
10973 (autoconf: forbidden tokens, exceptions): No longer sort
10974 autoconf's stderr, as it is now deterministic.
10975 Check that `dnl' is caught.
10977 2001-08-01 Akim Demaille <akim@epita.fr>
10979 * configure.ac: Bump to 2.52c.

10996 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
10997 `END', as `Autom4te::General::END' will be triggered.
10998 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
10999 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
11000 system to run `mv', `rm', and `cmp'.
