108 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
110 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
111 for a.* when searching for executables, as this prevents users
112 from having files like a.c. Problem reported by Ralf Wildenhues in:
113 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html

124 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
125 AC_CHECK_TYPE, AC_CHECK_TYPES.
126 * doc/autoconf.texi (Generic types): C types must be type-names
127 (the C terminology), not type-ids (the C++ term). C++ types
128 must not be anonymous.
129 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
130 for C++; this drops support for anonymous struct and union types,
131 which were problematic anyway.
132 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
133 for C++.
135 2007-04-12 Jim Meyering <jim@meyering.net>

147 * doc/autoconf.texi (Generic Types): Document the restrictions
148 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
149 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
150 with objects too. Document the restrictions on its use.
151 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
152 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
153 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
154 works but the latter doesn't, then it's a valid type.
155 This lets people use function types and so forth.
156 For C++ there doesn't seem to be a simple solution, so leave it alone.
157 (AC_CHECK_SIZEOF): Allow argument to be a variable.
158 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
159 AC_CHECK_TYPE; that wasn't documented or necessary.
161 2007-04-11 Stepan Kasal <kasal@ucw.cz>
163 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
164 when cross-compiling.

176 2007-04-06 Paul Eggert <eggert@cs.ucla.edu>
178 * doc/autoconf.texi (Particular Types): AC_C_LONG_DOUBLE is now
179 obsolescent. Suggested by Bruno Haible.
180 * NEWS: Document this.
182 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
184 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
185 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
186 default still has the problem. Problem reported by Bruce Korb.
188 2007-03-28 Stepan Kasal <kasal@ucw.cz>
189 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

206 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
207 checks for unsigned long long int.
209 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
211 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
212 nonstandard grep R.E. escape sequences.
214 2007-03-17 Jim Meyering <jim@meyering.net>
216 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
217 (Limitations of Usual Tools): Also list \< and \>, and mention that
218 HP-UX's grep, like the one from Solaris, does not support that syntax.
220 2007-03-09 Stepan Kasal <kasal@ucw.cz>
222 * doc/autoconf.texi (Specifying Names): `--host' does not
223 change the build type.
225 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
227 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
228 suggests AC_CONFIG_HEADERS.
229 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using

239 universal binaries. Problem reported by Elias Pipping.
241 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
243 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
244 * doc/autoconf.texi (C Compiler): Document this. There is a new
245 extra argument ACTION-IF-UNIVERSAL.
246 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
247 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
248 Reindent for sanity's sake.
250 2007-02-24 Eric Blake <ebb9@byu.net>

258 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
260 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
261 status of rm so we know when it failed.
262 If cleaning of test dir failed before running the test, warn.
263 Output the line separator in verbose mode before the warning
264 to make clear the warning belongs to the following test.
266 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

275 errors introduced in last change.
277 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
279 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
280 an actual carriage return. Use "ac_cr" to contain the actual
281 carriage return.
282 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
283 with traditional Awk and begin.
284 * tests/torture.at (Limitations of Builtins): Document the problem

314 2007-01-31 Eric Blake <ebb9@byu.net>
316 * THANKS (people): Update.
318 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
320 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
321 latest version.
322 (Shell Substitutions): Note problems with @{var:=value} etc.
323 Add a new section for problems with @{#var} etc. Problem noted
324 by Ralf Wildenhues. See:

327 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
329 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
330 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
331 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
332 substitution will still be done by the special code.
333 Report by Jim Meyering.
335 * doc/autoconf.texi (File System Conventions): Mention that
336 $PATH_SEPARATOR is for the build system only.
337 Report by Keith Marshall.
339 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

346 * tests/torture.at (Substitute and define special characters):
347 Test all 8 bit non-NUL characters.
348 Report against Automake by Patrick Welche.
350 2007-01-15 Stepan Kasal <kasal@ucw.cz>

354 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
356 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
357 early on the reader side, drop stderr of the input to avoid
358 `broken pipe' error output; this may happen even with shell
359 builtin `echo' of some bash versions. Reports by Ian Macdonald
360 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
362 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
364 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
365 separate items of `ac_user_opts', to avoid long lines.

374 Fix some wording problems noted by Paolo Bonzini in:
375 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
376 * doc/autoconf.texi (Signed Overflow Examples): Give more
377 discussion about the allow_superuser_privileges example,
378 and change it a bit to make things clearer.
379 (Optimization and Wraparound): Clarify whether the compiler
380 will generate an infinite loop for the example derived from
381 Autoconf's mktime test.
382 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
383 Also, clarify unsigned multiplication overflow.
385 2007-01-04 Eric Blake <ebb9@byu.net>
387 * bin/Makefile.am (RELEASE_YEAR): New macro.
388 (edit): Use it to supply correct copyright year to scripts.
389 * bin/autoconf.as (version): Use it.
390 * bin/autoheader.in ($version): Likewise.
391 * bin/autom4te.in ($version): Likewise.
392 * bin/autoreconf.in ($version): Likewise.
393 * bin/autoscan.in ($version): Likewise.
394 * bin/autoupdate.in ($version): Likewise.
395 * bin/ifnames.in ($version): Likewise.
397 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
399 * doc/autoconf.texi (Integer Overflow): Revised based on today's
400 feedback. The most important changes document what happens when
401 you convert an out-of-range value to a signed integer type, and
402 say that (sum < a) != (b < 0) reliably detects overflow when sum =
403 a + b.
405 * doc/autoconf.texi (Integer Overflow): Greatly expand and
406 rewrite, taking notions from the recent discussion on the gcc and
407 autoconf mailing lists; please see
408 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
409 and follow the many links.
410 (Integer Overflow Basics, Signed Overflow Examples):
411 (Optimization and Wraparound, Signed Overflow Advice):
412 (Signed Integer Division): New sections.
414 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
416 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
417 preprocessor macro arguments in traced name.
418 * doc/autoconf.texi (Defining symbols): Document longstanding
419 support for AC_DEFINE-ing macros with arguments, and document
420 behavior when the same variable has multiple AC_DEFINEs.
421 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
422 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
423 macros directly, giving much shorter and simpler code.
425 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
427 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
428 space before "$ac_configure_args" to prevent a 'config.status
429 --recheck' failure if ac_configure_args doesn't contain a leading
430 space. This works around a problem with the XEmacs configure.ac,
431 which uses the (undocumented) ac_configure_args variable
432 inconsistently with Autoconf.
434 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
436 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
437 Include <limits.h>, and use its INT_MAX to rewrite the
438 j loop so that it does not overflow 'int'. Problem reported by
439 Ralf Wildenhues in
440 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
441 Play it safe by shifting left by 1 rather than multiplying by 2,
442 as GCC is less likely to optimize this away when the value
443 is signed (when it assumes overflow leads to undefined behavior).
444 Also, don't assume time_t uses two's complement.
446 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
448 * tests/torture.at (Substitute a 2000-byte string): Avoid using
449 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
450 dumps core on it. Report by Tim Rice.
452 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
454 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
455 --disable-option-checking to --help output even when
456 AC_PRESERVE_HELP_ORDER is not used.
457 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
458 --with argument, rather than argument with [-.] replaced by
459 underscores.
460 * NEWS: Fix typo in previous change; the news was in the
461 wrong section.
463 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
465 * NEWS: Warnings are now generated by default for unknown
466 --enable-* and --with-* options.
467 * doc/autoconf.texi (Option Checking): Renamed from
468 (Configure Option Checking). Tighten up the wording a bit.
469 (External Software, Package Options): Cross-reference to Option
470 Checking, and use this to shorten our section.
471 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
472 "$x" to test "x$foo" != x.
473 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
474 Don't warn if $enable_option_checking is "no".
475 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
476 ac_unrecognized_opts to the empty string.
477 Don't echo the unrecognized opts, as this might mishandle
478 backslashes or leading -.
479 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
480 usage next to the other --disable-FEATURE options in the
481 help string.
483 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
485 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
486 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
487 Print warning for unrecognized --with and --enable options
488 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
489 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
490 Disable option checking when subdirs are configured.
491 (AC_OUTPUT): If warnings are enabled, print warning about
492 unrecognized --with and --enable options at the end of
493 the configure output (as well as at the beginning).
494 * doc/autoconf.texi (Option Checking): New node.
495 Document new option warning functionality.
497 2006-12-16 Eric Blake <ebb9@byu.net>
499 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
500 * NEWS: Start news for current version.
502 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
504 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
505 Define HAVE_GETMNTENT to 1, not to the empty string.
506 Problem originally reported by Jochen Friedrich in
507 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
509 This change prompted by a problem report by Andrey Simonenko in
510 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
511 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
512 object-like macros only, in the traditional portable character
513 set.
514 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
515 Warn about attempts to define things that are not identifiers.
516 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
517 awful hack that AC_DEFINEd macro names containing parentheses.
519 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
521 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
522 too drastic, even if Texinfo in theory requires it for info mode.
524 (config.status Invocation): Renamed back from Recreating a
525 Configuration).
526 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
527 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
529 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
531 * NEWS: Version 2.61a.
533 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
534 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
536 * NEWS: Document changes with echo and printf, and the lack
537 of limits on the total size of multi-line values of substituted
538 variables, and the AC_FUNC_FSEEKO fix.
540 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
542 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
543 Writing configure.ac.
544 (Autoconf Input Layout): Renamed from configure.ac Layout.
545 (Recreating a Configuration): Renamed from config.status Invocation.
546 (Obsolete Recreation): Renamed from Obsolete config.status Use.
547 (acconfig Header): Renamed from acconfig.h.
548 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
549 (Writing Testsuites): Renamed from Writing testsuite.at.
550 (Autom4te Cache): Renamed from autom4te.cache.
552 * BUGS: Remove mention of VPATH problem, since it's now documented
553 not to be a bug in the Autoconf build procedure itself, but rather
554 a problem with the proprietary `make' programs.
556 * doc/autoconf.texi (Build Directories): Add a cross reference
557 to VPATH and Make.
559 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
560 * doc/standards.texi: Sync from gnulib.
562 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
563 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
564 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
565 generated automatically.
567 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
569 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
570 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
571 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
573 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
575 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
576 `CEOF$ac_eof' special marker, the awk script cannot contain a
577 line matching `^CEOF', so this is not needed any more.
578 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
579 special marker in the test.
581 2006-12-06 Stepan Kasal <kasal@ucw.cz>
583 * tests/tools.at (autom4te preselections): Use `find -newer';
584 remove one of the sleeps.
586 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
587 more readable, using ...
588 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
590 * doc/autoconf.texi (autoheader Invocation): Do not double-
591 quote the parameter of `AH_BOTTOM' in the example.
593 2006-12-05 Stepan Kasal <kasal@ucw.cz>
595 * doc/autoconf.texi (Configuration Headers): Remove the
596 example with multiple input files.
597 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
598 multiple input files.
600 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
602 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
603 creating the awk substitution script, handle one input line at a
604 time, so that the maximum length of a substituted (multi-line)
605 value is not limited by the size of the sed pattern space.
606 The trade-off is a slightly repetitive sed script.
607 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
608 can only have up to 7 characters, due to Solaris 10 /bin/sed.
609 * tests/torture.at (Substitute a 2000-byte string): Increase the
610 test with several long lines, they should not be caught by sed
611 limits any more.
613 * tests/tools.at (autom4te preselections): New test, to flag
614 entries missing from autom4te.cfg.
615 Report by David Byron <dbyron@hheld.com>.
617 * tests/torture.at (Substitute a 2000-byte string): Actually use
618 AC_PROG_AWK, so the last change works as intended.
619 (Substitute and define special characters): Likewise.
620 (Substitute a newline): Likewise.
622 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
623 instead of `awk' consistently.
624 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
625 * tests/torture.at (Torturing config.status): Test both the
626 result of AC_PROG_AWK and plain awk.
627 (Substitute a 2000-byte string): Likewise.
628 (Substitute and define special characters): Likewise.
629 (Substitute a newline): Likewise.
631 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
633 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
634 can be assigned to a function pointer. Problem reported by
635 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
636 part of a patch by Ralf Wildenhues in that same bug report.
638 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
640 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
641 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
643 2006-12-01 Eric Blake <ebb9@byu.net>
645 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
646 cross-compiling from cygwin to mingw.
647 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
648 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
649 to lib/autoconf/c.m4.
651 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
653 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
654 string for more reliable failure. Wrap the entire test that
655 causes the broken Solaris printf to dump core, in a subshell,
656 so the segmentation fault message is reliably suppressed.
657 Fix shell expansion errors by using /usr/ucb/echo always;
658 avoid an error on systems without it by another subshell.
659 Avoid m4 expansion of `$1'. Set the zeroth argument of the
660 subshell-$as_echo to `as_echo', for better error message.
662 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
664 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
665 `BASH_SOURCE' contain a newline, set them to empty, as they may
666 not be unset.
668 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
670 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
671 years and is too hard to maintain now. The last straw was
672 reported by Jerker Baeck in
673 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
674 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
675 * doc/autoconf.texi (Particular Functions): Move
676 AC_FUNC_SETVBUF_REVERSED from here...
677 (Obsolete Macros): ... to here. Say that it does nothing now.
678 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
679 Turn into (almost) a no-op.
681 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
682 (AC_C_VOLATILE):
683 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
684 These macros are obsolescent and new applications shouldn't need them.
685 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
686 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
687 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
688 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
689 (AC_FUNC_VPRINTF): Likewise.
690 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
691 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
692 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
694 * doc/autoconf.texi (Setting Output Variables): Mention that
695 @VAR1@VAR2 has unspecified behavior. Problem reported by
696 Ralf Wildenhues.
697 * NEWS: Mention this.
699 * Makefile.am: Put only a single '#' into the copyright notice,
700 so that it's also present in the output file. Standardize wording
701 in makefile copyright notices to match GNU coding standards.
702 * bin/Makefile.am: Likewise.
703 * doc/Makefile.am: Likewise.
704 * lib/Makefile.am: Likewise.
705 * lib/freeze.mk: Likewise.
706 * lib/autoconf/Makefile.am: Likewise.
707 * lib/autoscan/Makefile.am: Likewise.
708 * lib/autotest/Makefile.am: Likewise.
709 * lib/m4sugar/Makefile.am: Likewise.
710 * man/Makefile.am: Likewise.
711 * tests/Makefile.am: Likewise.
712 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
713 one-line file.
715 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
717 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
718 in the sed script that mangles the awk script: delete up to the
719 first exclamation mark only.
720 * tests/torture.at (Substitute and define special characters):
721 Test '!' too.
723 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
725 Rewrite config files generation: avoid quadratic growth in
726 the number of substituted variables by using awk instead of sed
727 for the bulk of the substitutions.
728 * NEWS: Mention this.
729 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
730 forbidden in the output (and thus input) file.
731 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
732 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
733 generate just one large awk script for substitutions,
734 eliminating much of the earlier complexity, while adding some
735 new complexity. Only expand the substitution templates at
736 configure time, for smaller configure script size. If
737 _AC_SUBST_FILES are used, test 'awk' for working getline support
738 at config.status time. If absent, interpolate through the
739 shell. The awk script was written with much help
740 from Paolo Bonzini and Paul Eggert.
741 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
742 (_AC_SED_FRAG_NUM): Likewise.
743 (_AC_SUBST_CMDS): Renamed from...
744 (_AC_SED_CMDS): ...this.
745 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
746 * tests/torture.at (Substitute a 2000-byte string): Also
747 substitute a line with 1000 words, and a variable with several
748 long lines.
749 (Substitute and define special characters): Test awk special
750 characters, and put substitution input strings `@foo@' in the
751 output, to test that no recursion happens; test several other
752 combinations from Paolo Bonzini.
754 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
756 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
757 that replaced echo with AS_ECHO where this wasn't necessary.
758 Problem reportd by Ralf Wildenhues.
759 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
760 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
761 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
763 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
765 * lib/freeze.mk (GREP): Removed, no need to initialize this.
767 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
769 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
770 that traditional Awk lacks 3-arg "split". It has it.
771 Mention that FS must be a single character, and a few other
772 99-byte limits of traditional Awk.
773 Mention that if (i in a) doesn't work with traditional Awk.
775 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
777 * tests/autotest.at (BSx641-newline in command):
778 (BS-BS-newline in command, BSx640-newline in command):
779 (Newline-CODE-BS-newline in command):
780 (Single-quote-BS-newline in command):
781 (Single-quote-newline-BS-newline in command):
782 Use printf '%s\n' instead of echo, for portability to hosts
783 where echo interprets backslashes. This will break on hosts
784 that lack printf, but for now let's assume all such hosts
785 are dead (if not, we should get reports of test failures).
787 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
789 'echo' has some portability problems, when given a first argument
790 with a leading '-', or when given any argument containing '\'.
791 Avoid using 'echo' in these cases.
792 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
793 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
794 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
795 * lib/autotest/general.m4 (AT_INIT): Likewise.
796 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
797 argument might be unportable.
798 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
799 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
800 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
801 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
802 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
803 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
804 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
805 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
806 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
807 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
808 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
809 (AC_PROG_MAKE_SET): Likewise.
810 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
811 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
812 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
813 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
814 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
815 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
816 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
817 * bin/autoconf.as: Redo verbose flag implementation, as the old
818 scheme wouldn't work with AS_ECHO.
819 * lib/autotest/general.m4 (AT_INIT): Likewise.
820 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
821 Don't use ECHO_T, since ECHO_N is now reliable.
822 * lib/autotest/general.m4 (AT_INIT): Likewise.
823 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
824 rather than using a here-document to put the script into a file.
825 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
826 use AS_ECHO.
827 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
828 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
829 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
830 bug, but we might as well stop using ECHO_N and ECHO_C internally.
831 * lib/autotest/general.m4 (AT_SETUP): Likewise.
832 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
833 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
834 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
835 operand, as AS_ECHO requires. Avoid double file name expansion.
836 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
837 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
838 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
839 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
840 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
841 Double-quote strings that would otherwise contain M4 comments.
842 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
844 * configure.ac (AC_INIT): Bump to 2.61a.
845 * NEWS: Likewise.
847 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
849 Version 2.61.
851 * configure.ac (AC_INIT): Bump to 2.61.
852 * NEWS: Likewise.
854 * tests/autotest.at (Macro with backslash in a test title):
855 Comment out for now, as this tests neither fails nor passes
856 reliably. Problem reported by Ralf Wildenhues.
858 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
860 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
861 in previous change, which caused test failures.
863 2006-11-16 Stepan Kasal <kasal@ucw.cz>
865 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
866 code for --enable, --disable, --with, and --without to...
867 (_AC_INIT_PARSE_ENABLE): ... a new macro.
868 * doc/autoconf.texi (Package Options):
869 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
871 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

930 first argument may also contain dots.
932 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
934 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
935 benefit of platforms like Solaris+GCC where it is common to have a
936 non-working g++ installation.
938 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
939 and Joel E. Denny <jdenny@ces.clemson.edu>

948 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
949 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
950 Imported from a similar patch to gnulib by Bruno Haible.
952 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

975 properly.
976 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
977 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
978 argument. Extend to check titles printed by ./micro-suite and
979 ./micro-suite -l and the title in micro-suite.log.
980 (Backquote in a test title,
981 Single-quote in a test title,
982 Double-quote in a test title): Don't expect failure anymore.
983 (Backslash in a test title): Put a non-whitespace character after the
984 backslash so that Bourne shells might actually see it as an escape
985 sequence.
986 (Brackets in a test title,
987 Pound in a test title,
988 Comma in a test title,
989 Quoted Macro in a test title,

995 * tests/torture.at (#define header templates): M4-quote this title in
996 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
997 The visible effect was a stray [] in the testsuite output.
999 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1001 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
1002 `trap ... 0' inside a function, for AIX sh.
1004 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1006 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1007 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1008 5363) simply issues a warning when dividing by zero at compile
1009 time. Problem reported by Elias Pipping.
1011 2006-10-26 Eric Blake <ebb9@byu.net>
1013 * THANKS: Update.
1014 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1015 show effect on macros that expand with commas.
1016 Reported by Joel E. Denny.
1018 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

1043 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1044 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1045 reported by Nelson H. F. Beebe for Coreutils 6.4.
1047 * tests/tools.at (autoconf --trace: user macros): Remove test
1048 for tracing multiline macros, since m4 1.4.7a uses a different
1049 way to number lines. Problem reported by Ralf Wildenhues.
1051 2006-10-24 Stepan Kasal <kasal@ucw.cz>
1053 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1054 /dev/null since the heuristics for interactive behaviour was
1055 fixed in CVS m4.
1057 * bin/autom4te.in: With --force, always refresh the output
1058 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

1079 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1080 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
1082 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1111 looking for special shell characters.
1112 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
1113 macro defined by AS_VAR_PUSHDEF before passing it as a
1114 parameter.

1125 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1127 (Imported from Automake.)
1128 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1129 which incorrectly sets the mode of an existing destination
1130 directory. In some cases the unpatched install-sh could do the
1131 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1132 system. We hope this is rare in practice, but it's clearly worth
1133 fixing. Problem reported by Alex Unleashed in
1134 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1135 Also, don't bother to check for -m bugs unless we're using -m;
1136 suggested by Stepan Kasal.

1144 is enabled by default with gnu and gnits strictness.
1145 Report from Bruno Haible.
1147 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
1148 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
1149 gnu and gnits modes.
1151 Import this change from Config:
1153 2006-09-20 Ben Elliston <bje@gnu.org>

1156 Import this change from Gnulib:
1158 2006-09-16 Karl Berry <karl@gnu.org>
1159 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
1160 to avoid sectioning errors.

1173 * build-aux/texinfo.tex (\textdegree): New command.
1175 2006-08-12 Karl Berry <karl@gnu.org>

1180 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
1182 2006-10-13 Stepan Kasal <kasal@ucw.cz>
1184 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1185 added to the template can get mangled.
1187 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1189 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1190 include the default headers, and redefine obstack_chunk_alloc
1191 and obstack_chunk_free. Fixes false failure with glibc.
1193 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1195 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
1196 for backward compatibility with Libtool 1.5.22. Problem reported
1197 by Ralf Wildenhues.
1199 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1201 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
1202 AC_PROG_CC.

1205 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>

1210 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1212 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1213 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1214 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1215 Use a better substitute, by inspecting the output of "ls"
1216 rather than just using ":".
1217 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1218 rather than AS_EXECUTABLE_P, since we needn't worry about
1219 non-regular files here.
1221 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1222 due to configuration hassles with this. See Tonya Underwood's report
1223 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1224 * doc/autoconf.texi (Special Shell Variables): Likewise.

1232 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1234 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1235 initialization which is not inherited through the environment
1236 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1237 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1239 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1241 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1242 problems with mkdir -p -m.
1244 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1246 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1247 comment about ac_cpp_err; it was incorrect, and anyway
1248 ac_cpp_err is being removed below.
1249 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1250 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1251 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1252 nobody uses it.
1253 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1254 with werror_flag and conftest.err and so forth. This is more
1255 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1256 and anyway the user shouldn't normally want to see this gorp logged.
1257 Problem reported by Ralf Wildenhues.
1258 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1259 empty, not 'no', since the rest of the code uses 'test -z'.
1261 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1263 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1264 Use a single call to AC_DO_TOKENS rather than multiple, for
1265 efficiency.
1266 (_AC_LINK_IFELSE): Test that resulting file is executable.
1267 Problem reported by mwoehlke in
1268 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1270 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1271 than creating a file to use with test -x; this is much faster.
1273 2006-10-02 Bruno Haible <bruno@clisp.org>
1275 * lib/autom4te.in (Automake-preselections): Add
1276 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1278 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1280 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1281 standard error, `experr' should be used, not `expout'.
1283 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1285 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1286 fseeko testing program twice; just use the earlier result.
1287 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1288 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1289 still doesn't let the program compile.
1290 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1291 failed.
1293 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1294 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1295 include it, without including anything else.
1296 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1297 expressions.
1298 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1300 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1302 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1303 `error.h', and include it, for a `error_at_line' prototype.
1304 Use a nonempty format string in the link test.
1305 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1306 for a declaration of wait3.

1310 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1311 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1312 can apply to constants too, and that it checks for macro defns.
1313 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1314 and simply cast the identifier to void. This handles structure
1315 values. Problem reported by Ralf Wildenhues.
1316 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1318 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1373 --error-output, to avoid warnings with M4 2.0.
1375 2006-09-19 Stepan Kasal <kasal@ucw.cz>

1405 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check

1407 too late, anyway. Problem reported by Stefan Seefeld.
1409 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
1410 7.1.4 /usr/bin/posix/sh described by Tim Rice in

1415 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
1416 works with GNU M4 1.4.3 again; make the normalized form
1417 match the current m4 message; fix the description.
1418 * test/tools.at (autom4te cache): Adapt to the change.
1420 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
1422 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
1423 to catch glibc bug 2821
1424 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
1426 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1427 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1428 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
1429 assume C89.
1431 2006-09-08 Stepan Kasal <kasal@ucw.cz>
1433 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

1443 2006-09-05 Paul Eggert <eggert@cs.ucla.edu>
1445 * doc/autoconf.texi (Preset Output Variables): srcdir and
1446 top_srcdir are not necessarily relative. Problem reported
1447 by Dries Kimpe.
1449 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1451 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1452 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1453 accept files with extension `.f'. For consistency, also prefer
1454 xlf over f77.
1455 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
1456 from last patch.
1458 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

1471 before AC_PROG_FC, due to a bug in Autoconf.
1473 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
1475 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
1476 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
1477 except the first two arguments are reversed.
1478 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1479 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
1480 caches nor outputs a diagnostic. Suggested by Bruno Haible.
1481 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
1482 equivalent to the old AC_COMPUTE_INT.
1483 (AC_COMPUTE_INT): No longer caches or reports. New signature.
1484 All uses changed to AC_CACHE_CHECK_INT.
1485 * tests/base.at (AC_CACHE_CHECK_INT): New test.
1486 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
1488 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
1490 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
1491 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
1492 programs should use their Gnulib counterparts.
1493 * doc/autoconf.texi (Particular Functions): Likewise.
1494 (Macro Names, testsuite Invocation): Replace uses of these
1495 obsolete macros with uses of non-obsolete macros.

1518 * lib/Autom4te/General.pm (END): Use `File::Path::rmtree' to
1519 simplify the code.
1521 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
1523 Fix Lex library problem reported to us by Julio Garvia.
1524 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
1525 for the default, which the user can override.
1526 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1527 deal with LEXLIB.
1528 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1529 didn't work if some values were cached but not others. Test for
1530 broken lex libraries like native ia64-hp-hpux11.22; see
1531 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1532 work around the problem by preferring an empty LEXLIB to -lfl or
1533 -ll. Let the user set LEXLIB='' to indicate no library needed.
1535 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1536 * README: Likewise.
1537 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
1539 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>

1636 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1638 * doc/autoconf.texi (Particular Programs): Mention that
1639 @INSTALL@ and @MKDIR_P@ may vary for different output files.
1640 Reported by Alexandre Duret-Lutz.
1642 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
1644 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
1645 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
1646 Bill Northcott in
1647 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
1649 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>

1660 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1661 -Wundef -Werror". Problem reported by David Fang in
1662 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1663 * doc/autoconf.texi (Header Templates, Default Includes):
1664 (Particular Functions, Generic Functions, Header Portability):
1665 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
1666 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

1677 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
1678 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1679 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1680 this.

1684 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1685 problems with arg script text that doesn't end in newline, and

1696 to last change.
1698 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1700 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1701 --help' should mention that `--version' outputs configuration
1702 settings. Report by Bruno Haible.
1704 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1706 Fix test suite failures reported by Pierre in
1707 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1708 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1709 the compiler created a file "b.out" when it didn't create anything
1710 at all.

1722 less skeptical about "volatile", after discussion with
1723 Bruno Haible on bug-gnulib.
1724 (Limitations of Usual Tools): Warn about sed stripping
1725 leading white space from text. From Bruno Haible.
1727 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1729 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1730 compiler complains about it, even if things works after the
1731 complaint. Problem reported by Peter O'Gorman.
1733 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1734 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1735 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1737 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1739 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1740 after -R regardless of host. Patrick Welche reports that this
1741 fixes things on NetBSD 3.99.
1743 * NEWS: Recommend M4 1.4.5.
1744 * README: Likewise.
1745 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
1746 * tests/tools.at (autom4te cache): Update wording of diagnostic
1747 to match M4 1.4.5.
1749 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1751 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1752 under AC_C_VOLATILE.
1753 (Volatile Objects): Be a little less skeptical about what
1754 "volatile" means. Derived from thoughts by Ben Pfaff in
1755 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1757 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1759 * doc/autoconf.texi: Fix some typos.
1761 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1763 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1764 more globally, since the 2006-06-30 patch didn't suffice. Problem
1765 reported by Keith Marshall. Also, don't bother with builddir2,
1766 since it shouldn't be needed any more.
1768 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1770 * doc/autoconf.texi (Generic compiler characteristics):
1771 Document AC_COMPUTE_INT. Fix wrong statements on Default
1772 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1774 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.

1785 * NEWS: Document previous change.
1787 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1789 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1790 Require that long long int be at least 64 bits wide. C99 requires
1791 this and enough programs depend on it so we should check for it.
1792 Bruno Haible reports in
1793 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1794 that long long int is 32 bits wide with some nonstandard compilers.
1795 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1797 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1799 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1800 to a nonexistent file, so that we don't have to worry about
1801 a local site configuration that doesn't use /usr/local.
1802 Problem reported by Keith Marshall in
1803 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1805 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1807 * doc/autoconf.texi: Be more consistent about using @acronym with
1808 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1809 quite right (it talked about "OSF/Tru64", even though the
1810 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1811 and it even mentioned "OSF 4"!) and at this point there's little
1812 reason to talk about OSF any more, since it died in 1994.
1813 (Specific Compiler Characteristics): Simplify example of
1814 negative-size array.
1815 (File Descriptors): Reorder to make the text flow better.
1816 Remove joke about "appreciate the various levels"; I didn't get it.
1817 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1818 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1819 (File Descriptors, Limitations of Usual Tools):
1820 Tone down the advice against renaming or removing open files.
1821 (Limitations of Usual Tools): Add a new section, on 'rm'.
1823 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1825 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1826 -lXt in LIBS, idea from Karsten Hopp; this was due since
1827 this change:
1829 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1830 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1831 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1832 (which belong to Xt, not X itself). See Debian bug 327655.
1834 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1836 * configure.ac (AC_INIT): Bump to 2.60a.
1837 * NEWS: Update.

1845 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1847 * config/texinfo.tex: Sync from upstream.
1849 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1850 quadrigraph correctly in traces.
1852 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1853 Fix typos.
1855 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1856 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1857 not defined.
1858 * doc/autoconf.texi (Changed Directory Variables): New node,
1859 to document the whole `datarootdir' business a bit better.
1860 * NEWS: Update.
1861 * tests/torture.at (datarootdir workaround): Extend test.
1862 Prompted by report by Alexandre Julliard.
1864 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1866 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1867 when using default mode of IBM C 6 for AIX. Problem and two-line
1868 fix reported by Larry Jones.
1870 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1872 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1873 about literal '${datarootdir}' if a definition is found in the
1874 output file.
1876 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1878 * NEWS: Use "M4" rather than "m4" when appropriate.
1879 Problem reported by Eric Blake.
1880 * doc/autoconf.texi: Likewise.
1881 Use @acronym around BSD, GCC, and GNU when appropriate.
1882 (Why GNU M4): Renamed from "Why GNU m4".
1883 (Redefined M4 Macros): Mention that Posix
1884 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1885 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1886 to int.
1888 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1890 * bin/autom4te.in (handle_output): Do not forbid the empty
1891 pattern.
1892 * tests/tools.at (autoconf: the empty token): New test.
1894 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1896 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1897 calls, so that we do not care whether they are LIFO or FIFO;
1898 in the m4_wrap, do not check which diversion is the topmost
1899 one, just check that the stack is balanced at the end.
1900 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1901 base diversion forever--pop the previous diversion before
1902 opening the new one; consequently, remove the m4_wrap call.
1903 * lib/autotest/general.m4 (AT_INIT): Likewise.
1904 * tests/m4sugar.at: Do not use
1905 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1907 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1908 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1910 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1911 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1912 Rework example of m4wrap token-pasting trouble so that it doesn't
1913 care whether it's LIFO or FIFO.
1914 Fix some "contrary to"s that are awkward in English.
1916 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1918 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1919 to `yes' instead of `int$1_t' if the type is found, for more
1920 consistent configure output (where $1 is the number of bits).
1921 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1922 Suggested by Bruno Haible.
1924 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1925 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1926 with system headers. Report by Bruno Haible.
1928 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1930 * config/config.guess, config/config.sub: Sync from upstream.
1932 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1933 in order to avoid picking up an older installed frozen m4sh.m4f.
1934 Besides an outdated shell startup, this could have been created
1935 by an earlier M4 version with incompatible frozen file format.
1937 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1939 * README: Recommend m4 1.4.4 instead of 1.4.3..
1940 * doc/autoconf.texi: Likewise.
1941 (Special Chars in Names): Say that $(.FOO) is portable, as
1942 suggested by Stepan Kasal.
1943 (Installation Directory Variables, Build Directories):
1944 (Automatic Remaking, Subdirectories, Fortran Compiler):
1945 (Making testsuite Scripts, Defining Directories):
1946 Quote variable usages better.
1947 (Making testsuite Scripts): Add clean-local rule to makefile
1948 snippet, by Eric Blake.
1949 (Installation Directory Variables): Fix table item font.
1950 Reword slightly to clarify. Generalize advice about
1951 not using special characters to include all file-related
1952 vars, not just VPATH.
1953 (Special Chars in Variables): Warn about special characters in
1954 $(srcdir) too.
1955 (Assignments): Clarify default-value example as suggested by
1956 Ralf Wildenhues in
1957 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1958 (Special Shell Variables): Note leading ./ or ../, as suggested
1959 by Eric Blake.
1960 (Limitations of Builtins): Under cd, warn about CDPATH.
1961 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1962 Ralf Wildenhues.
1964 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1966 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1967 `@var', for texi2html.
1968 (Systemology): Some more word wrapping, for DVI output.
1969 (autom4te Invocation): The short option for `--melt' is `-M',
1970 not `-m'.
1972 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1974 * doc/autoconf.texi: More formatting and English tweaks,
1975 many suggested by Ralf Wildenhues.
1976 Reword to avoid "@code{...}'s" and the like, since it's ugly
1977 with Emacs info mode. discontents -> woes.
1978 Put a few "will"s back. time stamp -> timestamp.
1979 side-effect -> side effect.
1981 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1983 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1984 Warn about $@ not persisting. Problem reported by Julien Danjou in
1985 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1986 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1987 Mention other special chars, too.
1989 2006-06-14 Eric Blake <ebb9@byu.net>
1991 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1993 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1995 * doc/autoconf.texi: Some systematic minor improvements, as
1996 follows. Use "makefile" when talking about makefiles
1997 generally (which might be named "makefile" or "Makefile" or even
1998 "foo.mk"), "Makefile" when talking about a specific makefile
1999 called "Makefile". This unclutters the text from weird quotes
2000 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2001 values" rather than "@var{foo}s" and similar constructs containing
2002 "}s". Use "Make rules" rather than "Makefile rules". Minor
2003 English-language improvements. Change the prefix "sub-" to "sub"
2004 and "re-" to "re".
2005 Put blank lines around examples more consistently.
2006 Avoid "rather" and "very" as intensifiers.
2007 Avoid "will" as an auxiliary.
2008 (Limitations of Make): Split this node into....
2009 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2010 (Leading _ in Macro Names, Backslash-Newline-Newline):
2011 (Backslash-Newline Comments, Long Lines in Makefiles):
2012 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2013 (obj/ and Make, make -k Status, VPATH and Make):
2014 (VPATH and Double-colon, $< in Explicit Rules):
2015 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2016 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2017 New nodes, resulting from splitup of Limitations of Make.
2018 All cross-references changed. Raise the top node from
2019 a section to a chapter, and all subnodes accordingly.
2020 Redo the introductory wording to match the new organization.
2021 (Installation Directory Variables): Use an example that is
2022 closer to what Autoconf actually does. Mention that VPATH's
2023 value should not contain metacharacters or white space.
2024 (Fortran Compiler): Fix a VPATH bug in an example.
2025 (Leading _ in Macro Names): Mention that this problem is no longer
2026 of practical concern.
2027 (VPATH and Make): Reword the advice to make it clearer
2028 that Autoconf and Automake support VPATH in non-GNU make, but
2029 many packages have bugs in this area.
2030 ($< in Explicit Rules): Refer to Build Directories rather
2031 than using a (non-VPATH-safe) example.
2032 (Automatic Rule Rewriting): Mention the sort of disaster that
2033 can ensue with Solaris-style rule rewriting with VPATH.
2035 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2037 * doc/install.texi (Compilers and Options): Weaken the
2038 suggestion to use GNU make for VPATH builds.
2040 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2041 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2043 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2044 in regular expression.
2046 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2048 * doc/autoconf.texi (Installation Directory Variables):
2049 Drop extra @samp from `@table @samp' item.
2050 (Limitations of Usual Tools): Comment fix.
2051 Do not nest @samp just to point to other table items.
2052 (Writing testsuite.at) <AT_CHECK>: The second argument to
2053 `@dvar' is already @samp'ed.
2054 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2055 do not use @var in the second argument.
2057 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2059 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2060 $as_shell.exe too. Problem reported by Andreas Buening in
2061 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2063 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2065 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2066 `unused variable' compiler warning, for `-Wall -Werror'.
2067 Reported by Jaap Haitsma in
2068 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2070 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2072 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2073 case the compiler dumps core. Problem reported for
2074 OpenServer 5.0.7 by Tim Rice in
2075 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2076 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2077 Likewise.
2079 2006-06-06 Tim Rice <tim@multitalents.net>.
2081 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2082 "ERROR" only shows up in "make check" output if there is an
2083 error.
2085 2006-06-06 Eric Blake <ebb9@byu.net>
2087 * tests/tools.at (automatically allowed tokens): Fix typo.

2091 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2093 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2094 typically overflows on x86 CPUs, even though the C standard
2095 requires otherwise.
2097 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2099 * configure.ac (AC_INIT): Bump to 2.59e.
2100 * NEWS: Update.
2102 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2104 Version 2.59d.
2106 * config/texinfo.tex: Sync from upstream.
2108 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2109 seen, invoke libtoolize with `--ltdl' argument.
2110 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2111 * NEWS: Update.
2112 Suggested by Eric Blake.
2114 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2116 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

2133 * tests/base.at: Check AC_REQUIRE's error message.
2134 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2135 to...
2136 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2137 AT_CHECK_M4.
2138 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2139 `expout' as the last parameter.
2140 * tests/tools.at: Adapt to the above change.
2142 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2144 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2145 information about race-free implementations of mkdir.
2147 2006-06-04 Eric Blake <ebb9@byu.net>
2149 * bin/autoreconf.in (help): Document M4 environment variable.
2150 * bin/autoconf.as (Usage): Likewise.
2151 * bin/autom4te.in (help): Likewise.
2152 * doc/autoconf.texi (autom4te Invocation): Likewise.
2154 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2156 * NEWS: GNU make now recommended for VPATH builds.
2157 Mention that some macros are now documented to be obsolescent.
2158 * doc/autoconf.texi:
2159 Prefer "current" to "modern" to describe
2160 currently-used (albeit perhaps old-fashioned) hosts.
2161 Mention which ancient features no longer need to be worried about.
2162 setgid -> set-group-ID
2163 setuid -> set-user-ID (these are the Posix terms)
2164 Fix some misuses of "only".
2165 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2166 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2167 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2168 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2169 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2170 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
2171 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
2172 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):

2174 Mention that these macros are obsolescent.
2175 (Installation Directory Variables): shall -> should
2176 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2177 Mention that it's now safe to use 3 and 4.
2178 (Limitations of Usual Tools): cp -r is now specified by Posix.
2179 Omit longwinded and obsolescent discussion of cp -f.
2180 Modernize discussion of expr, ls.
2181 (Limitations of Make): Modernize discussion of VPATH builds.
2182 Mention $? as a workaround in some cases.
2183 * doc/install.texi (Basic Installation):
2184 Mention "./configure; make; make install" first. Be more
2185 specific about why this file is generic. Remove unnecessary
2186 parens. Remove misleading "only". Remove obsolete advice
2187 about csh. Don't say "configure" takes awhile; say it
2188 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2189 and CC=c99 rather than CC=c89, as these are blessed by current
2190 Posix. Recommend GNU make if doing a VPATH build.
2192 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2194 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2195 examples involving shell prompts.
2197 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2198 and Paul Eggert <eggert@cs.ucla.edu>
2200 * doc/autoconf.texi (Here-Documents): Add details about the
2201 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2202 use "here-documents" instead of "here documents".
2204 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2206 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

2216 about quoting the case statement, just in case.
2217 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2218 was fixed in ksh93g; reported by Ralf Wildenhues.
2220 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2222 * doc/autoconf.texi (System Services): Do not document
2223 overriding EXEEXT via ac_cv_exeext=ext.

2225 Document that ${MKDIR_P} understands --.
2226 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2227 comment.
2229 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2231 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2232 argument with leading hyphen. Problem reported by Paul Eggert.
2234 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2236 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2237 about quoting ac_try: quote all of it, if any of it seems suspicious.
2238 This means we don't have to worry about ${ or sed any more.
2239 Also, double-quote the case statement, to work around misuses via
2240 underquoting as reported by Ralf Wildenhues in
2241 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2242 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2243 undocumented and dangerous macro.
2244 Problem reported by Ralf Wildenhues in
2245 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2247 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2249 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether

2251 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2253 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2255 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2256 since evidently some packages rely on the old, broken behavior.
2257 Problem reported by Ralf Wildenhues in
2258 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2259 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2260 pre-2006-05-26 definitions, but leave in the comments that
2261 these macros are dangerous and should not be used.
2262 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2263 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2264 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2265 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2266 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2268 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2270 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2271 the use of 'tr', since this is our only use of 'tr'.
2273 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2274 and Paul Eggert <eggert@cs.ucla.edu>
2276 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2277 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2279 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2281 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2282 the output file in the `${datarootdir}' test.
2284 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2285 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2287 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2288 mention of `datarootdir' in the input file(s), but literal
2289 `${datarootdir}' in the output file, and we haven't warned yet,
2290 then warn as well: the user may have (erroneously) used
2291 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2292 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2293 * tests/torture.at (datarootdir workaround): Extend this test.
2294 * NEWS: Update.
2296 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2297 and Paul Eggert <eggert@cs.ucla.edu>
2299 * doc/autoconf.texi (autoheader Invocation): The first argument to
2300 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2301 alternatives and clear up the language a bit.
2303 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2305 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2306 ac_config_guess, ac_config_sub, ac_configure.
2307 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2308 Fix typo that prevented an unnecessary space from being removed.
2309 Problems reported by Ralf Wildenhues in:
2310 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2312 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2314 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2315 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2316 Don't use the term "thread-safe" to talk about mkdir race
2317 conditions, since the problem is more a process than a thread
2318 issue. Problem reported by Stepan Kasal in:
2319 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2320 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2321 the test for 'install' more closely. Look at MKDIR_P first.
2322 Look in the PATH, and at /opt/sfw/bin.
2323 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2324 Don't bother to try mkdir -p, since we already check mkdir --version;
2325 just look at the version number. (There's no easy way to check
2326 for race-free implementations.)
2327 * tests/tools.at (autoconf: subdirectories): Adjust to above
2328 changes, since MKDIR_P now might end in "/mkdir -p".
2330 * doc/autoconf.texi (autoheader Invocation): Mention that the
2331 first arg of AC_DEFINE_UNQUOTED must be a literal.
2332 Problem reported by Ben Pfaff in
2333 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2335 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2336 * doc/autoconf.texi (Special Chars in Variables): New section.
2337 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2338 (Installation Directory Variables): Quote $(datadir) better.
2339 (Limitations of Builtins): Describe some of eval's trickiness.
2341 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2342 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2343 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2344 in front of every arg, not just trailing args. Quote apostrophes.
2345 (_AC_EVAL_ECHO): New macro.
2346 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2347 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2348 removed.
2349 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2350 exposed by quoting of eval argument. Put the command on line line
2351 so it logs better.
2352 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2353 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2354 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2355 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2356 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2357 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2358 Use eval more safely.
2359 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2360 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2361 to be replaced.
2362 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2363 lines, exposed by quoting of eval argument.
2365 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2366 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2368 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2369 initialization of `ac_cv_exeext', do not override it if it was
2370 already set, unless it was set to `no', for compatibility with
2371 Autoconf-2.13, and comment this.
2372 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2373 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2374 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2375 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2376 Document that this test may be overridden by setting
2377 `ac_cv_exeext'.
2379 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2381 Revert these two patches:
2383 2006-04-06 Eric Blake <ebb9@byu.net>
2384 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2385 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2386 2006-04-01.
2388 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2389 Clean up _AC_COMPILER_EXEEXT* macros.
2390 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2391 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2392 ac_file to the name of the default output file and call
2393 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2394 initial `rm' of the candidate files...
2395 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2396 the same list in subsequent `rm' calls, and for the temporary
2397 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2398 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2399 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2400 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2401 no longer needed) by libtool. Make it a cache check.
2402 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2403 copied here by mistake.
2404 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2405 _AC_COMPILER_EXEEXT.
2406 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2407 _AC_COMPILER_OBJEXT directly.
2408 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2410 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2412 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2413 Fix description of how the buggy `sed' works.
2415 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2417 Sync from Automake:
2419 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2420 ENOLCK. Only mention `make -j' when applicable. Only raise
2421 fatal errors when `make -j' is involved. Improve error message.
2423 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2425 * doc/autoconf.texi (Here-Documents): We now know more about
2426 the variable expansion in here documents bug.
2427 Thanks to Tim Rice and Stepan Kasal.
2429 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2430 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2432 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2434 * tests/autotest.at (Multiline command from M4 expansion):
2435 No failure to be expected if the shell quotes newlines in
2436 commands in the `set -x' output. Report by Tim Rice.
2437 * THANKS: Update.
2439 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2441 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2442 expansion in the here-documents used by config.status, as that
2443 runs afoul of the Korn shell version M-12/28/93d bug described in
2444 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2445 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2446 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2448 2006-05-23 Jim Meyering <jim@meyering.net>
2450 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2451 Fix typo introduced with 2006-04-02 change. It reversed the sense
2452 of the test.
2454 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2456 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2457 ac_dB slightly, to save bytes in the script.
2458 Max out at 50 lines, rather than 96; this is more likely
2459 (though not guaranteed) to avoid obscure 'sed' failures.
2461 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2463 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2464 `tr -d -' as bad option argument. Work around this by deleting
2465 an unrelated character.
2466 Report by Tim Rice <tim@multitalents.net>.
2468 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2469 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2470 Stepan Kasal <kasal@ucw.cz>
2472 * doc/autoconf.texi (Particular Programs): Do not promise that
2473 we always prefer the GNU version of the program, and that we
2474 search according to PATH; both rules can have exceptions.
2475 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2476 AC_PROG_SED. Move descriptions of limitations
2477 to the Limitations of Usual Tools section.
2478 (Limitations of Usual Tools) <sed>: Mention script length
2479 limitations with Solaris /usr/ucb/sed.
2480 <grep>: Fix wording for empty alternative. Mention that -c and
2481 -l should not be combined, and that -E and -F should not be
2482 combined.
2484 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2485 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2487 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2488 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2490 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2492 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2493 AC_DEFINE is now passed to m4_pattern_allow.
2494 * NEWS: Mention that; likewise for AC_SUBST.
2495 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2496 the parameter to m4_pattern_allow.
2497 * tests/tools.at: Add a check for that.
2499 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2501 * lib/autoconf/status.m4: Fix typos.
2503 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2505 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2506 only the files that this macro generates.
2508 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2510 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2511 the HP-UX sed limitation of 99 commands, labels do not count.
2512 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2513 in the comment.
2514 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2516 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2518 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2519 Import the following fix from coreutils:
2521 2006-01-13 Jim Meyering <jim@meyering.net>
2523 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2524 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2525 not double-quote uses of that variable, to accommodate the rare
2526 case in which getmntent is available in none of the libraries
2527 checked. This happens at least on FreeBSD 5.0.
2529 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2531 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2532 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2533 some other programs unwisely rely on these undocumented vars.
2534 But put in warning comments about them.
2535 Problem reported by Ralf Wildenhues in
2536 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2537 * NEWS: Document that these variables are intended to go away.
2539 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2541 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2542 and set the language to C++ (analogous to the equivalent Fortran
2543 tests).
2545 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2546 * doc/autoconf.texi (C++ Compiler): Document it.
2547 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2548 * NEWS: Update.
2550 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2552 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2553 that caused config.status to generate 100-command sed scripts; the
2554 portable limit is 99.
2556 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2558 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2559 variable `ac_d' instead of `d' to avoid infringing namespace.
2560 Report by Ralf Menzel.
2562 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2564 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2565 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2566 * tests/tools.at (autoconf: subdirectories): New test, taken from
2567 the corresponding problem report by Ralf Wildenhues in:
2568 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2570 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2571 Quote some uses of shell variables if they might suffer unexpected
2572 globbing. This doesn't fix all instances of quoting problems that
2573 I found, just the easy ones that look safe.
2574 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2575 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2576 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2577 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2578 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2579 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2580 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2581 Likewise.
2582 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2583 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2585 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2587 * bin/autoreconf.in ($help): Reword according to the manual.
2588 Suggested by Olly Betts.
2590 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2591 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2593 * bin/autoreconf.in: Pass the directory argument to
2594 `require_configure_ac'. Fix comment.
2595 * tests/torture.at (Configuring subdirectories): Expose this.
2596 Reported by Olly Betts.
2598 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2600 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2601 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2602 Automake as follows:
2604 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2605 `$configure_in' instead of `configure.in', to preserve
2606 directory component.
2608 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2610 * config/config.guess, config/config.sub, config/texinfo.tex,
2611 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2613 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2615 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2616 test for C99 conformance; (bool) 0.5 is an integer constant
2617 expression, but (bool) -0.5 is not. Problem reported by Fedor
2618 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2620 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2622 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2623 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2624 Warn about obsolete install-sh files. Remove stray sentence
2625 fragment and fix cross reference.
2626 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2627 install -d; this undoes the 2006-05-10 change.
2628 (MKDIR_P): Mark with AN_MAKEVAR.
2629 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2630 that we don't require $INSTALL to be thread-safe. Move comments
2631 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2632 of AC_PROG_INSTALL. Output a message saying that we're checking
2633 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2634 MKDIR_P instead of AC_SUBST.
2635 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2636 Special magic for MKDIR_P, too.
2637 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2638 a dnl.
2639 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2641 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2643 Sync from Automake, as follows:
2645 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2646 * config/install-sh: Initialize IFS, so field splitting isn't
2647 turned off later.
2648 * config/mkinstalldirs: Likewise.
2649 * config/missing: Remove superfluous quotes. Replace all uses of
2650 `[' by `test', for consistency, and for..
2651 * config/missing (sed_minuso, sed_output): New variables.
2652 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2653 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2654 Fixes `missing' to detect `--output' for help2man. Fixes
2655 PR automake/483. Report by Dennis J. Linse.
2656 (autom4te): Document in `missing --help'.
2658 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2660 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2661 * config/install-sh: Don't use 'path' to talk about file names,
2662 as per GNU coding standards. Close a race condition reported by Ralf
2663 Wildenhues and Stepan Kasal. There is still a race condition
2664 on hosts that predate Posix 1003.1-1992, but we can't help this.
2665 Don't mishandle weird characters like space on pre-Posix hosts.
2666 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2667 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2668 AC_PROG_MKDIR_P from AS_MKDIR_P.
2669 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2670 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2671 earlier editions are not (including Automake 1.8.3).
2672 Do not suggest mkinstalldirs for thread-safety.
2673 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2674 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2675 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2676 presence of special characters and race conditions.
2677 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2678 in Autoconf's name space.
2680 2006-05-10 Bruno Haible <bruno@clisp.org>
2681 and Paul Eggert <eggert@cs.ucla.edu>
2683 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2684 from Automake with minor changes.
2685 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2687 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2689 * config/install-sh: Update to Automake CVS version, as follows:
2690 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2691 * lib/install-sh: Simplify the expr implementation of dirname.
2692 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2693 * lib/install-sh: Handle --, and diagnose unknown options.
2695 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2697 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2698 `./autom4te' to create `./testsuite', since the `all' target
2699 will ensure its presence, but `installcheck' should not create
2700 the uninstalled wrappers.
2702 * tests/torture.at (Unusual Automake input files): Skip if we
2703 detect automake < 1.8.
2705 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2707 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2708 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2709 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2710 * NEWS: Update.
2712 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2714 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2715 munge (multiple) white space and other oddities.
2716 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2717 single quotes in variable assignment.
2718 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2719 and similar failures by adding multiple spaces, tabs, and other
2720 special characters.
2721 Report and different test suggested by Francesco Romani
2722 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2724 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2725 single quotes, we only need to search for single quotes; this
2726 both simplifies the search pattern, and makes us less
2727 susceptible to `echo' variations for arguments not containing
2728 single quotes.
2729 (_AC_ARG_VAR_VALIDATE): Likewise.
2731 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2733 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2734 `$*' and IFS concatenation issue with traditional shells and

2747 and Bruno Haible <bruno@clisp.org>
2749 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2750 about 'od'.
2751 (Integer Overflow): Mention the special case of integer division
2752 overflow.
2754 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2756 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2757 traditional shells like the Solaris one that do not use the
2758 first IFS character for assembling `$*'.
2759 Prompted by a related report from autoconf_bug@nro.ca.
2761 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2762 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2764 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):

2785 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2787 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2808 with status 1, not merely nonzero. Clarify exit declaration.
2809 (Run Time): Move C exit status stuff to new Exiting Portably section.
2810 (Systemology): Mention Posix and levenez. Update v7 reference.
2811 (Portable Shell): Mention the Posix shell.
2813 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2815 * bin/autoconf.as (me): Replace by as_me.
2817 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2819 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2820 since as_me isn't set yet.
2822 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2824 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2825 a few minor bugs in this area.
2827 * doc/autoconf.texi (Programming in M4sh): Comment out the
2828 documentation of AS_BASENAME, for now.
2829 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2830 (Limitations of Builtins) <basename>: Do not refer to
2831 AS_BASENAME.
2832 * bin/autoconf.as (me): Don't use AS_BASENAME.
2833 (dir): Remove the unused variable.
2834 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from

2854 * lib/autoconf/general.m4: Likewise.
2855 * lib/autoconf/headers.m4: Likewise.
2857 * doc/autoconf.texi (Run Time): Document the exit status situation
2858 with more accuracy and detail.
2860 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2862 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2863 Archive is not officially `GNU' any more. Update URL.
2864 (Defining Directories): Likewise
2865 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2867 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2869 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2870 newline from the `trap' code to finish `config.log'; the NetBSD
2871 /bin/sh resets the exit status after an empty command, as
2872 documented in doc/autoconf.texi.
2873 Reported by Dalibor Topic <robilad@kaffe.org>.
2875 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2877 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2878 Suggested by Bruno Haible.
2880 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2882 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2883 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2884 Instead, just list the shells that we know work.
2885 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2886 changed. Be more cautious about the _cv_ variable.
2887 * tests/tools.at (Syntax of the shell scripts): Check the
2888 _cv_ variable once, at first, to avoid an internal autoconf error
2889 when sh -n does not work.
2891 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2893 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2895 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2897 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2898 use ">&-" since we're only 99.999% sure that this is portable,
2899 and since the MinGW bug is fixed in a different way.
2900 * lib/autotest/general.m4 (AT_INIT): Likewise.
2902 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2904 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2905 before opening config.log, to avoid hitting a bug on MinGW.
2907 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2909 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2910 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2911 This works around a MinGW bug reported by Eric Paire.
2912 Make sure that all writes to the log file append to it,
2913 rather than possibly losing data.
2914 * lib/autotest/general.m4 (AT_INIT): Likewise.
2916 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2918 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2919 description.
2921 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2923 * NEWS: Update.
2925 * configure.ac (AC_INIT): Bump to 2.59d.
2927 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2929 Version 2.59c.
2931 * Makefile.maint (news-date-check): Do not require a leading `*'
2932 before the release date in NEWS.
2934 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2935 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2937 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2938 the instantiated file do not contain the string 'datarootdir'
2939 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2940 @mandir@, replace the reference '${datarootdir}' by the value.
2941 * tests/torture.at (datarootdir workaround): New test.
2942 * NEWS: Advertise this temporary fixup.
2943 Based on a patch by Bruno Haible, reported and analyzed by
2944 Paul Eggert and Noah Misch.
2946 2006-04-12 Eric Blake <ebb9@byu.net>
2948 * tests/autotest.at (Debugging a failed test): Fix comment.
2950 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2952 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2953 all the changes since 2006-04-07.
2955 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2957 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2958 succeeded, but `ln -s file dir' failed, take care to remove the
2959 leftover target before the next test, to prevent its spurious
2960 failure; also make sure `ln file dir' works before selecting it.
2961 Thanks to Keith Marshall for pointing this out.
2962 * THANKS: Update.
2964 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2965 assignments in `at_debug_args', so that we put them correctly
2966 in the `run' script.
2967 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2968 Reported by Eric Blake.
2970 2006-04-11 Eric Blake <ebb9@byu.net>
2972 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2973 top-level tests after micro-suite has been run. Used in...
2974 (Debugging a successful test, Debugging script and environment),
2975 (Debugging a failed test): ...these new tests. The first of these
2976 is fixed by...
2977 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2978 macro, split out from...
2979 (AT_INIT): ...here, so that using -d also generates a run script.
2980 Document that -d inhibits top-level logging.
2981 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2982 inhibits top-level logging; debug scripts are created.
2984 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2985 check.
2986 * tests/autotest.at (Empty test, Empty check): New test to check it.
2988 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2989 from gcc.
2991 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2993 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2994 the files if a problem appears. Make the empty *.at files
2995 read-only, too. Proposed by Ralf Wildenhues.
2997 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2999 * config/Makefile.am: Add comment to force updated Makefile.in.
3001 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3002 space only patch to this file, this patch causes the Makefile.in
3003 files that include freeze.mk to be updated, and thus have a
3004 newer time stamp again, which in turn makes a pristine CVS
3005 checkout have correct time stamps.
3007 * Makefile.maint (cvs-sv): New macro, to be used..
3008 (config.guess-url_prefix, config.sub-url_prefix)
3009 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3010 point to CVS text checkout of Gnulib files.
3011 (copyright-check): Bump current year.
3012 (announcement): Do not hard-wire `./announce-gen'.
3013 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3014 correctly.
3015 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3016 `chmod +x'.
3017 (wget_files): Update config.guess, config.sub, texinfo.tex by
3018 `wget-update', now that their URLs work again.
3020 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3022 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3023 Problem noted by Paul D. Smith.
3025 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3027 * doc/autoconf.texi: Remove unused words from word list.
3028 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3029 .x-sc_trailing_space: New files.
3031 * doc/standards.texi: Sync from gnulib.
3033 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3034 `LIBOBJDIR' as experimental.
3036 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3037 with a target directory; it's internally implemented as `cp'
3038 anyway, but since Autoconf advertises the possibility to use
3039 a target directory when LN_S is `ln -s', we need to find out.
3040 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3041 analyzed by Keith Marshall <keith.marshall@total.com>.
3043 * THANKS: Update.
3045 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3047 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3048 confdefs.h as-is. In general, if it has backslash-newline or the
3049 like, then it doesn't work either to sort or to remove empty
3050 lines.
3052 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3054 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3056 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3058 * lib/autom4te.in (Automake-preselections): Preselect
3059 _AM_SUBST_NOTMAKE.
3061 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3063 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3064 apostrophe within a single-quoted string, as this is the usual
3065 tradition and is easier to read than '"'"'. Don't rely on the
3066 shell treating "$/" like '$/'. Use a more-consistent indenting
3067 style for the trap.
3069 2006-04-09 Eric Blake <ebb9@byu.net>
3071 * tests/autotest.at (Backquote command substitution),
3072 (Multiline backquote command substitution): Remove mistaken
3073 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3074 applied...
3075 (Parenthetical command substitution, Multiline parenthetical
3076 command substitution): here.
3078 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3080 Import macros from gnulib (often changing their name).

3094 (Pointers): Add Gnulib URL.
3095 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
3096 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3097 Gnulib section.
3098 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
3099 suggest a #define rather than a typedef for _Bool, and mention
3100 Gnulib rather than trying to substitute stdbool code.
3101 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
3102 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
3103 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
3104 AC_STRUCT_DIRENT_D_TYPE.

3106 headers too.
3107 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3108 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
3109 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
3110 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
3111 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3112 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3113 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3114 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3115 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3116 (Coding Style). Don't mention m4_expand_once.

3125 (AC_HEADER_ASSERT): New macro.
3126 (AC_HEADER_STDBOOL): Don't assume "#error" works.
3127 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
3128 Catch a bug in an HP-UX C compiler.
3129 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
3130 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
3131 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

3134 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
3135 New macros.
3137 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
3138 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
3140 2006-04-08 Stepan Kasal <kasal@ucw.cz>
3142 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
3143 of the warning introduced by the 2001-08-28 change.
3145 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
3146 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3148 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
3149 variables shall be overriden by the cache.
3150 * tests/torture.at (AC_ARG_VAR): Test also with a first value
3151 that contains braces.
3153 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3155 Revert the patch from 2006-04-01 and only improve
3156 _AS_DETECT_BETTER_SHELL:
3158 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3159 skip nonexistent directories.
3160 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3161 only shell candidates which exist.
3162 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3163 * lib/autotest/general.m4 (AT_INIT): No need to give three
3164 parameters to _AS_PATH_WALK.
3166 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3167 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3169 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3170 distinguish m4sugar macros.
3171 * tests/tools.at (autoupdating with aclocal and m4_include):
3172 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3173 test case by Noah Misch <noah@cs.caltech.edu>.
3175 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3177 Revert my change from 2006-03-17, in other words:
3178 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3179 and DUALCASE=1.
3180 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3181 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3182 it is set.
3184 2006-04-07 Eric Blake <ebb9@byu.net>
3186 * doc/autoconf.texi (Programming in M4sh): Document that
3187 AS_MKDIR_P exits the script on failure.
3188 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3190 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3192 * config/elisp-comp, config/install-sh, config/mdate-sh,
3193 config/missing, config/mkinstalldirs: Sync from Automake.
3195 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3196 from Automake.
3198 * doc/make-stds.texi: Sync from gnulib.
3200 2006-04-06 Eric Blake <ebb9@byu.net>
3202 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3203 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3204 2006-04-01.
3206 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
3207 Eric Blake <ebb9@byu.net>,
3208 Paul Eggert <eggert@cs.ucla.edu>,
3209 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3211 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3212 whether `set' quotes correctly: redirect stderr of the tested
3213 `set', and use a subshell, for Ultrix; use `sed' instead of
3214 `grep' for zsh `set' which may write binary output; match only
3215 at the beginning of a line, to avoid false positives.
3216 In order to avoid false positives by unrelated variables with
3217 multiline content, put the dump algorithm in a subshell and
3218 unset all variables containing newlines (except some which are
3219 special to the shell). Warn about cache variables that are
3220 unset.
3222 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3224 * config/config.guess, config/config.sub, config/texinfo.tex:
3225 Sync from upstream.
3227 * tests/mktests.sh: Reword comments.
3229 * tests/mktests.sh: Only skip internal macros starting with
3230 `_AC_' or `__AC_'. Noted by Stepan Kasal.
3231 Update exclusion lists for the test suite to this end:
3232 (AC_ARG_VAR): Do test this now.
3233 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3234 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3235 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3236 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3238 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3239 shell issue with double-quoted command substitutions of native
3240 commands.
3241 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
3242 Marshall.
3244 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
3245 no file matches the glob, discard the warning, set `nullglob'.
3246 (syntax-check): Likewise.
3247 (sc_cast_of_x_alloc_return_value): Likewise.
3248 (sc_cast_of_alloca_return_value, sc_error_exit_success)

3257 <tab><space> where this makes sense.
3259 2006-04-06 Stepan Kasal <kasal@ucw.cz>
3261 * tests/Makefile.am (maintainer-check-posix):
3262 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
3264 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
3265 ac_config_<foo>s again, sometimes normalized, sometimes not.
3266 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3267 (AC_CONFIG_COMMANDS): Do not do so here.
3268 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3269 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3270 2005-07-25 rewrite. Noticed by Noah Misch.
3272 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3273 _AC_PRESERVE_HELP_ORDER, ...
3274 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3276 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3277 inside m4_expand_once; it is redundant.
3279 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3280 for --help from Cygnus `configure.'
3282 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
3284 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
3285 on a patch proposed by Ralf Wildenhues.
3287 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3289 * lib/autoconf/status.m4: Replace <space>''<tab> with
3290 <tab><space> where this makes sense.
3292 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
3293 Noah Misch <noah@cs.caltech.edu>
3295 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3296 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3297 * doc/autoconf.texi (Help Formatting): New node.
3298 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3300 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3302 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3303 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3304 lib/autoconf/types.m4, lib/autotest/general.m4,
3305 tests/mktests.sh, tests/torture.at: White space cleanup:
3306 remove some SPACE before TAB, or add quoting ('' or @&t@).
3308 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
3310 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
3312 2006-04-05 Eric Blake <ebb9@byu.net>
3314 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
3315 empty test suite works.
3316 * tests/autotest.at (Empty test suite): Remove xfail.
3318 2006-04-05 Noah Misch <noah@cs.caltech.edu>
3320 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
3321 TAGS to ac_config_<foo>s.
3322 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
3323 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
3324 normalizing it, consistent it with previous releases.
3325 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3327 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3329 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3330 Use simplified args that Eric Blake originally suggested.
3332 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3334 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3335 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3336 Use 'comm' rather than N instances of grep; this also fixes a bug
3337 whereby substrings were incorrectly matched, causing us to not
3338 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3339 (exclude_list): Exclude empty macros.
3340 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
3342 Use awk rather than grep -E or egrep, to avoid
3343 portability problems with regular expressions containing newlines.

3345 Switch from grep to awk syntax.
3346 (ac_exclude_script): Renamed from ac_exclude_egrep.
3347 (au_exclude_script): Renamed from au_exclude_egrep.
3349 2006-04-04 Noah Misch <noah@cs.caltech.edu>
3351 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
3352 a subdirectory subject to Cygnus `configure'.
3353 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3355 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3356 report request when we have no AC_PACKAGE_BUGREPORT.
3358 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3360 * THANKS: Update.

3363 generated files.
3365 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
3366 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
3367 typedef'ed restricted pointer, to catch a compiler bug on
3368 HP-UX 11.x, and fix warnings so it passes with -Werror.
3369 (_AC_PROG_CC_C99): Likewise.
3370 Reported by Albert Chin <china@thewrittenword.com>.

3386 * THANKS: Add myself.
3388 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3390 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
3391 to log, point to testsuite output tree.
3393 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
3395 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
3396 * doc/autoconf.texi (Function Portability): Mention that C++
3397 has trouble with 'exit'.
3398 (Guidelines): Test programs shouldn't use 'exit'.
3399 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
3400 Remove; all uses removed.
3401 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

3421 Clean up _AC_COMPILER_EXEEXT* macros.
3423 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3424 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3425 ac_file to the name of the default output file and call
3426 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3427 initial `rm' of the candidate files...
3428 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3429 the same list in subsequent `rm' calls, and for the temporary
3430 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3431 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3432 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3433 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3434 no longer needed) by libtool. Make it a cache check.
3435 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3436 copied here by mistake.
3437 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3438 _AC_COMPILER_EXEEXT.
3439 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3440 _AC_COMPILER_OBJEXT directly.

3467 and fix some typos.
3469 2006-04-01 Noah Misch <noah@cs.caltech.edu>
3471 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
3472 Autoconf version number despite a zero- or one-argument AC_INIT.
3474 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
3475 subordinate tools.
3476 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
3477 * doc/autoconf.texi (autoreconf Invocation): Document it.
3479 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
3480 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.
3482 2006-04-01 Eric Blake <ebb9@byu.net>
3484 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Allow use in shell lists.
3485 * lib/autotest/general.m4: Be tolerant of existing directory when
3486 rm failed to remove it.
3488 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3490 * bin/autoupdate.in: Redefine m4_location so that warnings print
3491 the correct lines of the input file by subtracting..
3492 (_au__first_line): ..this new definition.
3494 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
3495 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
3496 Remove stray newline in output.
3497 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
3498 AC_DEFUN this for autoconf, including the obsoletion diagnose.
3499 Fixes autoupdating of code where the replacement output contains
3500 m4sugar macros.
3501 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
3502 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

3504 * tests/tools.at: Several new tests for all of this.
3505 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
3506 hairy details.
3507 The AC_LANG_SAVE issue was reported against Libtool by
3508 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
3509 Kristian Kvilekval <kris@cs.ucsb.edu>.
3511 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3513 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3514 switch all of them on and of when necessary. Fixes the bug when
3515 m4sugar macros (e.g., m4_define) were expanded after the first
3516 automatic update (e.g., after AC_PREREQ or AC_INIT).
3518 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

3543 aclocal cannot be given on the command line.
3545 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
3547 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
3548 Give an example for AS_DIRNAME instead of referring to Posix..
3549 (File System Conventions): Put discussion of // versus / here, and
3550 modernize it a bit.
3551 (Limitations of Usual Tools): Add basename. Remove verbiage
3552 after dirname, since it got moved to the above sections.
3553 All this was inspired by a patch proposed earlier by Eric Blake.

3561 `$0', $as_me.
3563 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3565 * bin/autoscan.in: The value of find_configure_ac should be
3566 checked for existence, so we don't barf over a nonexisting
3567 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
3569 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3571 * bin/autoupdate.in: Fix some typos.
3573 2006-03-21 Stepan Kasal <kasal@ucw.cz>
3575 * doc/autoconf.texi (Installation Directory Variables): Fix typo.
3577 * lib/autoscan/autoscan.list: Refreshed.

4088 shell from zsh to bash.
4090 2005-12-31 Stepan Kasal <kasal@ucw.cz>
4092 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
4093 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
4095 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>

4126 (Limitations of Builtins): Likewise.
4128 2005-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4130 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Pass
4131 CONFIG_SHELL in the environment of the configure rerun.
4132 * doc/autoconf.texi (Here-Documents, config.status Invocation):
4133 Suggest passing CONFIG_SHELL absolute, and in the environment
4134 rather than as option.
4136 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4138 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

4150 ac_clean_files and LIBOBJS.
4152 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4154 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
4155 Factor functionality to..
4156 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
4157 `AC_SUBST($1)' in the public version.
4158 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
4159 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
4160 ac_pt_* variables.
4162 2005-11-01 Stepan Kasal <kasal@ucw.cz>
4164 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
4165 filesystems.

4174 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4176 2005-10-25 Stepan Kasal <kasal@ucw.cz>
4178 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
4179 conftst2.$ac_objext.
4180 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4182 2005-10-24 Stepan Kasal <kasal@ucw.cz>
4184 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
4185 conftest.o, to see whether the compiler really obeys; rm the object
4186 file before and after the test and register it with ac_clean_files.
4187 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4189 2005-10-21 Stepan Kasal <kasal@ucw.cz>
4191 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
4192 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
4193 code so that the most common case requires less forks.
4195 2005-10-20 Stepan Kasal <kasal@ucw.cz>
4197 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
4198 not portable; thanks to Paul Eggert and Alexandre.
4200 * NEWS: Fix an old typo.
4202 2005-10-20 Jim Meyering <jim@meyering.net>

4205 the latter'', in two places.
4207 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
4209 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
4210 AC_LANG_PROGRAM, fixing a typo. Don't give details about
4211 the inner workings of AC_LANG_FUNC_LINK_TRY.
4212 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
4213 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4214 by the function rather than ignoring it.
4215 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4216 comparing its address. Intel's interprocedural optimization was
4217 outsmarting the old heuristic. Problem reported by
4218 Mikulas Patocka.
4220 2005-10-19 Stepan Kasal <kasal@ucw.cz>
4222 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
4224 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
4226 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
4227 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
4229 2005-10-04 Stepan Kasal <kasal@ucw.cz>
4231 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
4232 before removing it (chmod -R u+rwx); there are three instances of this.
4234 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4235 Stepan Kasal <kasal@ucw.cz>
4237 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4238 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4239 make its content writable before removing it. Remove an errorneous
4240 comment from the end, where the logs of the failed tests are copied
4241 to the main log file.
4243 2005-09-27 Stepan Kasal <kasal@ucw.cz>
4245 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
4246 in case the computer is too quick. Double quote the configure.ac
4247 snippets.
4249 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
4250 problems if the testsuite were running too fast.
4252 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4254 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4255 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4256 (which belong to Xt, not X itself). See Debian bug 327655.
4257 * NEWS: Mention this.
4259 2005-09-07 Stepan Kasal <kasal@ucw.cz>
4261 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
4263 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
4265 * config/move-if-change: Don't output "$2 is unchanged";
4266 suggested by Ben Elliston. Handle weird characters correctly.
4268 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4270 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4271 calls, so that the final expansion of this macro is shorter.
4272 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4273 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4274 the cleanup there. Use AS_VAR_* macros, to be more general.
4275 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4277 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4279 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
4281 2005-09-01 Stepan Kasal <kasal@ucw.cz>
4283 * doc/autoconf.texi (Configuration Headers): Add an index entry
4284 for AH_HEADER.
4286 2005-08-26 Pavel Roskin <proski@gnu.org>
4288 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
4289 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
4290 running xmkmf.
4292 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4294 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4295 The previous patch didn't work, so try a better one.
4297 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4299 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4300 in the example. Reported by Bruno Haible.
4301 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4302 "if $undefined_var;" succeeds with my shell.
4304 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4305 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4306 but change the m4_divert_text to m4_divert_once.
4308 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4310 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4311 Work around bug in Solaris /usr/xpg4/bin/awk.
4312 The bug is present in at least Solaris 8 through 10.
4314 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4316 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4317 some evil values and relying on the fact that $* concatenates the
4318 parameters by the first character from IFS.
4320 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4321 Stepan Kasal <kasal@ucw.cz>
4323 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4324 first header appears, define AH_HEADER.
4325 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4326 Update limitations about when to call AC_CONFIG_HEADERS.
4327 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4328 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4329 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4330 ``Configuration Actions''; fix their index entries.
4332 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4333 options correctly. Process N-M as M-N if M is smaller than N.
4334 Process ranges correctly so that N-N will run only N.
4335 Sort and uniquify the tests that will be run. If there is more
4336 than one test, reinsert the banners for the tests.
4337 * tests/autotest.at (Keywords): Unmark XFAIL.
4339 2005-08-23 Stepan Kasal <kasal@ucw.cz>
4341 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4342 before passing the macro name to AH_TEMPLATE.
4344 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4345 now opens log after option processing; in particular, --version
4346 and --help do not touch config.log.
4348 * Makefile.maint: Revert the change from 2005-08-12.
4350 2005-08-22 Stepan Kasal <kasal@ucw.cz>
4352 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
4353 common code to...
4354 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
4356 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4358 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4359 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4360 Language cleanup.
4362 * doc/autoconf.texi (Defining Symbols, Changed Results):
4363 Prepend to LIBS, not append, in examples.
4365 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4367 When building in place, set srcdir="."; suggested by Tim Van Holder.
4369 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4370 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4371 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4372 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4373 does not mean "no --srcdir option".
4375 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4377 * tests/autoscan.at (autoscan): New file.
4378 * tests/suite.at: Use it.
4379 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4380 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
4382 * tests/autotest.at (Keywords): Test keywords combinations.
4384 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4386 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4387 add "2>&1"; gzip 1.2.4 prints help on stderr.
4389 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4391 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4392 was pushdef'ed twice while popped only once. Push it only once.
4393 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4395 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4397 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
4398 prefixed by mere "===", not "configure: === ".
4400 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
4402 * Makefile.maint: Update from Bison.
4404 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4405 "<tab>" in comment, so that the point is understandable.
4407 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4409 Rewrite substantial part of lib/autoconf/status.m4.
4410 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4411 and CONFIG_COMMANDS are not processed in four separate loops.
4412 Instead, there is one main loop. This alows that the common code
4413 is expanded only once, thus config.status (and configure) is smaller.
4415 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4416 the AC_LIST_FILES and cousins macros are no longer used.
4418 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4419 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4420 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4421 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4422 contain the initialization, nor the for loop, nor the associated
4423 commands; all these go to ...
4424 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4425 _AC_OUTPUT_CONFIG_STATUS.
4426 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4427 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4428 (_AC_OUTPUT_FILE): The creation of the sed script ...
4429 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4430 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4431 _AC_OUTPUT_MAIN_LOOP.
4432 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4433 _AC_CONFIG_COMMANDS): Use ...
4434 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4435 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4436 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4437 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4438 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4439 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4440 ... new macros.
4441 (_AC_CONFIG_UNIQUE): Update.
4442 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4443 Replaced by this ...
4444 (_AC_LIST_TAGS): ... new common macro.
4445 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4446 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4447 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4448 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4449 this didn't belong to the `config commands' section.
4450 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4451 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4452 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4453 to the `config commands' section either.
4454 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4455 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4457 ... and many changes to the comments nearby.
4459 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4460 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4461 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4462 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4463 (#define header templates): The comment at the top of the generated
4464 header now includes the name(s) of the source file(s).
4466 Several unrelated small changes:
4468 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4469 parameter to AC_DIAGNOSE.
4470 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4471 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4472 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4473 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4474 with AU::AC_OUTPUT.
4475 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4476 in AC_OUTPUT doesn't double-quote it either.
4477 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4478 parameters.
4480 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4482 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4483 versions of Portland Group compiler produce single- and double-quoted
4484 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4485 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4487 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4489 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4490 This is a corrected version of yesterday's patch.
4492 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4494 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4495 path, too; insert a "===" to emphasize the line.
4497 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4498 ac_cv_build_alias to ac_build_alias.
4499 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4501 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4502 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4503 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4504 (AC_ARG_VAR): ... here.
4505 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4506 target_alias.
4508 Keep a list of all precious variables and process them with one simple
4509 for loop, instead of expanding all commands, or, OTOH, complicated
4510 processing of output of "set".
4511 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4512 variable names in new macro...
4513 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4514 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4515 a loop to assign all ac_env_* and ac_cv_env_* variables.
4516 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4517 to INIT_PREPARE.
4518 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4519 its value to shell variable ac_precious_vars and call
4520 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4521 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4522 _AC_ARG_VAR_VALIDATE.
4524 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4525 and the AC_SUBSTs ...
4526 (AC_INIT): ... here.
4528 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4529 the ac_subst_files section in config.log.
4531 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
4533 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

4543 They are generated by the Tru64 v5.1B shell.
4545 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4547 Fix my changes from 2005-07-01; reported by Noah Misch.
4548 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4549 description, the macro now accepts only a single tag.

4557 is not set, use at_top_builddir, for compatibility with older
4558 versions of autoconf.
4560 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4562 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4563 Problem reported by Patrick Welche.
4565 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4567 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4568 sed substitution command, so that we allow | in program prefixes
4569 and program suffixes. (& is a problem anyway; we're not fixing

4572 configure_input, top_builddir, srcdir, etc.
4573 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4574 PATH_SEPARATOR in AUTOTEST_PATH.
4576 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

4584 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

4602 about #include <config.h>.
4603 (Generic Functions): Mention the Gnulib project.
4604 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4606 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4607 document to output the default config_* lists to config.status.
4608 Don't recognize option --file, if the functionality is not there.
4609 Likewise for --header; moreover, recognize --he and --h as shortcuts
4610 for --help in that case.
4612 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4613 matches the order of execution. No code changed.

4635 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4636 (AC_SUBST): Call it.
4637 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4638 the directory specific variables; but don't call it for configure_input.
4640 2005-06-28 Derek Price <derek@ximbiot.com>
4642 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4643 addition.
4645 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4647 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4648 directory have inherent problems with special characters like spaces,
4649 due to limitations in Make syntax. Problem reported by Alexandre
4650 Duret-Lutz.
4651 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4664 from Justace Clutter.
4665 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4666 variable into diagnostic. Make the diagnostic an error, not a warning,
4667 because we really don't support spaces and suchlike in dir names.
4668 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4669 Don't worry about backslashes in srcdir; it can't happen now.
4670 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4671 Simplify ac_optarg handling.
4672 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

4682 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4683 that '\|' is not allowed in BREs; recommend using newline separated
4684 list of patterns instead of multiple -e options.
4686 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4688 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4694 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4696 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4697 b, t, r, w commands require single space, while : cannot have any.
4698 (Special Shell Variables): Fix sed code this in the example.
4699 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4700 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4702 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4703 expand to the empty list. Don't use two pairs of m4_changequote,
4704 it's not necessary.
4706 2005-06-20 Derek Price <derek@ximbiot.com>
4708 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4710 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4712 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4713 * doc/autoconf.texi:
4714 Don't mention Solaris versions so much, if a
4715 problem is common to all extant versions of Solaris. Say "SunOS
4716 4" instead of "SunOS" for SunOS 4.
4717 (awk): Mention more of the limitations of traditional Awk.
4718 (cat): Don't talk about cat -v.
4720 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

4725 to be compatible with glibc strverscmp.
4726 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4728 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4729 on Mac OS X 10.4 reported by Peter O'Gorman in:
4730 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4731 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4732 Use shell builtins rather than 'expr', to work around expr bug.
4734 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4736 * doc/autoconf.texi: "filesystem" -> "file system".
4737 "behaviour" -> "behavior".

4739 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4740 as per POSIX.
4741 * lib/m4sugar/m4sh.m4: Likewise.
4742 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4743 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4745 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4746 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4747 to update the man page. That way, we don't have to check in new
4748 man pages every month.
4750 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4751 quotes and backslashes. Patch from Derek Price.

4756 AS_TR_SH.
4758 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4760 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4761 -u, since it outputs chatter if the input files are the same.
4762 Problem reported by Ralf Menzel.
4764 2005-06-08 Derek Price <derek@ximbiot.com>
4766 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4767 renaming them since they are about to be redefined anyhow.
4769 2005-06-08 Derek Price <derek@ximbiot.com>
4771 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4772 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4773 Move m4_undefine to alphabetical order.
4775 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4777 * README: Recommend GNU M4 1.4.3 or later.
4778 * doc/autoconf.texi (Introduction): Likewise.
4779 Reword to avoid some formatting glitches.
4780 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4781 Clarify explanation of HP compiler bug.
4782 Redo example output tp match current CVS snapshot.
4783 Use @example.org in email addresses when the examples
4784 might get inadvertently cut-and-pasted into user code.
4785 Remove example of autom4te usage that doesn't seem to work now.
4786 Use modern AC_INIT (except when the example is meant to be
4787 shown with Autoconf 2.13).
4788 Update ksh info for Solaris 9 and later.
4789 KB -> kB.
4790 Modernize description of Automake versions a bit.
4791 Don't claim a future version of Autoconf is near.
4792 * doc/install.texi: Reword to avoid some formatting glitches.
4794 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4796 * doc/autoconf.texi: Add [] to examples, so that the manual
4797 follows its own advice about quoting better.
4798 Reword to avoid some formatting glitches.
4799 * doc/installt.exi: Reword to avoid some formatting glitches.
4801 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4802 Tru64 ksh pattern matching bug. Reported against Libtool by
4803 Albert Chin <libtool@mlists.thewrittenword.com> and
4804 Nicolas Joly <njoly@pasteur.fr>.
4806 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4808 m4_cdr of one-member list was [[]] (one-member list containing an
4809 empty string) instead of [] (an empty list. Callers were skewed to
4810 match this misbehaviour. As a consequence of this:
4811 - m4_foreach([x], [], [foo]) expanded to `foo', while
4812 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4813 This bug has been fixed:
4815 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4816 expand to an empty string; print error msg if called without
4817 an argument list.
4818 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4819 misbehaviour; handle [] and [[]] correctly.
4821 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4823 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

4825 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4827 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4829 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4830 swallow records with more than 99 fields.
4831 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4832 parse the long line.
4834 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4836 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4837 swallow literals longer than 399. Reported by Ralf Wildenhues.
4838 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

4841 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4843 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4844 to gfortran, and make these the first two compiler names
4845 checked (following the general autoconf preference for gcc).
4847 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4849 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4850 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4851 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4853 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4855 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4856 expression of unbounded size when processing the --list
4857 option. This runs afoul of a limit of 399 bytes per regular
4858 expression on AIX. Problem reported by Ralf Wildenhues.
4860 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

4863 * doc/autoconf.texi (Particular Headers): Reword example
4864 for multiline stdbool replacement.
4865 (Setting Output Variables): Reword text a bit. Don't
4866 give all the details about |#_!!_#|.
4867 Reword description of line replacement.
4869 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4871 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4872 now contain newlines, and substituted files must be referenced on
4873 a line alone; the sed scripts to substitute them are now very
4874 different.
4875 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4876 commands can be put in a sed script portably.
4877 * doc/autoconf.texi (Setting Output Variables): Document above
4878 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4879 use of multiline substitution.

4885 From Ralf Menzel (trivial change).
4887 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
4889 * tests/local.at: Don't attempt to check for negated character
4890 classes in shell scripts. The test was too brittle.
4892 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4894 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4895 * doc/autoconf.texi (Limitations of Builtins): Document this
4896 limitation.
4898 2005-05-24 Stepan Kasal <kasal@ucw.cz>

4908 messages when ac_unique_file is not found.
4909 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4910 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4911 commands, for consistency with AC_MSG_ERROR and such.
4913 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4915 * bin/Makefile.am: Merge the two rules for creating scripts.

4925 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4926 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4927 (ac_top_builddir): ... this ...
4928 (ac_top_build_prefix): ... to this; the old name is also kept, for
4929 backward compatibility.
4930 (ac_top_builddir_sub): New variable, without the trailing slash,
4931 always nonempty.
4932 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4933 * doc/autoconf.texi (Configuration Actions): Rename
4934 ac_top_builddir to ac_top_build_prefix.
4935 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

4944 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4946 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4947 argument to m4_foreach. I guess it was necessary in the past,
4948 but I think it's a no-op now.
4950 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4952 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4953 ``cat <<_ACEOF'' commands to one.
4954 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4955 * lib/autoconf/status.m4: On various places, use expr instead of
4956 ``echo|sed.''
4957 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4958 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4959 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4960 a range.
4961 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4962 the wrong patterns between ``case'' and ``esac.'' The previous
4963 code had false positives.
4965 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4967 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4968 as on 2005-05-02.
4969 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

5010 2005-05-13 Stepan Kasal <kasal@ucw.cz>
5012 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
5013 check.
5014 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
5015 enough arguments, similarly as in m4_bpatsubsts.
5017 2005-05-12 Stepan Kasal <kasal@ucw.cz>
5019 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

5024 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
5025 for absolute directory names in one loop.
5026 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
5027 abbreviations of --version and --debug.
5029 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
5031 * doc/autoconf.texi (Autoconf Language): Be more precise about
5032 quoting rules. Problems noted by Stepan Kasal.
5033 Also, throughout this document, be more careful about white space.
5034 "blank", "white space", and "space" all have different meanings
5035 and we should be careful to say what we mean.
5037 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
5039 Fix C++ related problems reported by Werner Lemberg.
5040 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
5041 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
5042 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
5043 avoid problems with C++ and throw.
5044 * tests/compile.at: .cpp, not .cc.
5046 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
5048 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5050 * doc/autoconf.texi (Generic Functions): Typos.
5052 2005-05-02 Gary V. Vaughan <gary@gnu.org>
5054 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
5055 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
5056 set by latest automake.
5058 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
5060 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
5061 outputs 0 on GNU/Linux these days.
5063 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
5065 * doc/autoconf.texi (Autoconf Language): Add more description
5066 about quoting heuristics.
5067 (Limitations of Builtins): Describe "set -" problems.
5069 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5071 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
5072 not newline.
5074 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5075 by AC_DEFINE; it was a mistake.
5076 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5078 2005-04-25 Stepan Kasal <kasal@ucw.cz>
5080 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
5082 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5084 * doc/autoconf.texi (External Software): Quadrigraphs are not
5085 processed correctly in AS_HELP_STRING; avoid this in the examples.
5086 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5087 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5088 comment and reduce m4_default([foo], []) to [foo].
5089 (m4_strip): Update the explanation.
5091 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5093 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5094 Remove core.conftest.* too; it's generated by Tru64 5.1.
5095 Problem reported by Jennis Pruett.
5096 * lib/autoconf/functions.m4
5097 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5098 Don't bother to remove core files; AC_RUN_IFELSE should do that
5099 for you.
5101 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5103 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
5105 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
5107 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
5108 Report from Horst Wente.
5110 2005-04-15 Stepan Kasal <kasal@ucw.cz>
5112 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
5113 the comment.
5115 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
5117 * doc/autoconf.texi (External Software, Package Options): Add
5118 examples showing how to implement --with-* and --enable-* options.
5120 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
5122 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
5123 as well as configure.in. Problem reported by Gregorio Guidi.
5125 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
5127 * doc/autoconf.texi (Particular Functions): Use gnulib's current
5128 pattern for alloca snippet.
5130 2005-04-04 Stepan Kasal <kasal@ucw.cz>
5132 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

5138 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
5140 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
5141 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
5143 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5145 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5146 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5147 whole-archive (-zallextract, -zdefaultextract) options in the hope of
5148 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5149 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5151 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5153 * NEWS: The configure command now warns you if you attempt to use
5154 a directory whose name contains a special character like space,
5155 newline, or "\".
5156 * doc/autoconf.texi (Installation Directory Variables): Allow
5157 "," in file names. Do not use \@; it's not a portable regexp.
5158 * bin/Makefile.am (edit): Likewise.
5159 * lib/Makefile.am (edit): Likewise.
5160 * tests/Makefile.am (edit): Likewise.
5161 * tests/semantics.at: Likewise.
5162 * tests/torture.at: Likewise.
5163 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
5164 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
5165 * doc/autoconf.texi (File System Conventions): Warn about
5166 unportable file names.
5167 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5168 (AC_INIT): Use it.
5169 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5170 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5171 ac_pwd, and quote srcdir.
5172 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5174 * doc/autoconf.texi: Fix some systematic formatting problems.
5175 ".)" needs a following @: if not at the end of a sentence, and
5176 similarly for "!)". "etc." should be preceded by a comma.
5177 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5179 2005-03-22 Bruno Haible <bruno@clisp.org>
5181 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5182 argument is often called 'build-aux'.
5184 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5186 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5187 macro AC_TRY_LINK is obsolete.
5188 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5189 `AC_CONFIG_FILES'.
5191 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5193 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5194 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5195 from a Common Lisp's `cl'.
5196 (AC_PROG_CXX): Behave according to the documentation: don't
5197 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5198 make the variable CCC precious; use `cl.exe', not `cl'.
5200 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5201 Alexandre Duret-Lutz <adl@gnu.org>
5203 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5204 /dev/null, as "configure" shouldn't read stdin, and this insulates
5205 us from problems (e.g., when testing for "cl"). Also, do this
5206 redirection before invoking "hostname" or "uname", and keep the
5207 original input stream available via...
5208 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5209 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5210 bother with "</dev/null" since it's now done at the top of
5211 'configure'.
5212 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5213 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5214 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5215 * doc/autoconf.texi (File Descriptor Macros): New section.
5216 (Printing Messages): Mention it.
5217 * tests/base.at (Input/Output): New test.
5219 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5221 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5222 newline if neither \c nor -n work, as that would output two
5223 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5225 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5227 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5228 This causes that any required macros inside will get before the if.
5229 * doc/autoconf.texi (autom4te.cache): A typo.
5231 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5233 Undo previous change, except keep the change to
5234 lib/autoconf/programs.m4 that replaced grep with shell
5235 pattern-matching. This is because net-snmp configure reads stdin.
5236 Reported by Noah Misch.
5238 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5240 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5241 from /dev/null, as "configure" shouldn't read stdin, and this
5242 insulates us from problems (e.g., when testing for "cl").
5243 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5244 before invoking "hostname" or "uname".
5245 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5246 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5247 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5248 "</dev/null" since it's now done at the top of 'configure'.
5249 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5250 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5251 Also, replace grep with shell pattern-matching, to save a process.
5253 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5255 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5256 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5257 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5258 compiler.
5260 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5262 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5263 grep -q isn't portable. Improve grep -s explanation.
5264 Problem reported by Dan Manthey.
5266 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5268 * doc/autoconf.texi (Special Shell Variables): Clarify
5269 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5271 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5273 * doc/autoconf.texi: Use @acronym for DJGPP.
5274 Fix some @code's that should have been @env's, and vice versa.
5275 Sort environment variable names.
5276 Mention that shells no longer inherit IFS.
5277 Don't recommend PATH_SEPARATOR=';' so strongly.
5278 Mention that $RANDOM might expand to the empty string.
5279 "symlink" and "soft link" -> "symbolic link".
5280 Improve mktemp description (reported by Bruno Haible).
5282 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5284 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5285 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5286 Likewise.
5287 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5288 Likewise.
5290 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5292 * NEWS: Mention AT_COPYRIGHT.
5294 * tests/local.at (AT_CMP): Use diff directly on input files rather
5295 than copying them.
5297 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5298 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5300 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5301 and Paul Eggert <eggert@cs.ucla.edu>
5303 * tests/autotest.at (Empty test suite): New test.
5304 * tests/torture.at (Substitute and define special characters)
5305 (Substitute a 2000-byte string, Define to a 2000-byte string)
5306 (Substitute a newline, Define a newline): New tests.
5308 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5310 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5311 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5312 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5313 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5314 (Standard regular expressions): New test.
5315 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5316 excess test name quoting.
5317 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5318 CPPFLAGS to `configure' instead of setting it in `configure'.
5320 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5321 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5322 on some platforms.
5324 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5325 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
5327 * tests/local.at (AT_CMP): New macro.
5328 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
5329 (AC_SAVE_STATE): Move environment grep...
5330 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
5331 (AT_CONFIG_CMP): New macro.
5332 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
5333 * tests/c.at (Extensions): Do not exit early.
5334 * tests/atlocal.in: Inherit $GREP.
5336 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
5337 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
5339 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
5340 (AC_COPYRIGHT): Factor header comment portion out and move into...
5341 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
5342 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
5343 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
5344 --version output.
5345 * tests/local.at: Add Autoconf test suite copyright notice.
5346 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
5348 2005-02-04 Bruno Haible <bruno@clisp.org>
5349 and Paul Eggert <eggert@cs.ucla.edu>
5351 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
5353 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
5355 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5356 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5358 Try not to generated lines of unlimited length, as POSIX places a
5359 2047-byte limit on line length of portable text files.
5360 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5361 Use newline as a separator, not space.
5362 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
5363 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
5364 space.
5366 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5368 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
5369 as_func_*. Add test to check whether positional parameters
5370 are restored after function return.
5372 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
5374 * doc/autoconf.texi (Special Shell Variables): Mention _,
5375 BIN_SH, DUALCASE. Say that variables other than "status" are safe
5376 if they contain a lower-case letter. The DUALCASE problem was
5377 reported by Ralf Wildenhues.
5379 * bin/autoconf.as: Don't exit with status 0 after write failure
5380 with --help or --version.
5381 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
5382 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
5384 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5386 * doc/autoconf.texi (Limitations of Usual Tools):
5387 Unicos 9 sed limitations.
5388 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
5389 to get the option-enhanced interface on older Crays. Try ftn for
5390 Fortran 95 (newer Crays).
5392 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
5394 * man/Makefile.am (.x.1): Go back to the simple solution, but take
5395 care to echo the commands, so the user knows what's going on.
5396 Modified from a suggestion by Stepan Kasal.
5398 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
5399 with a cross reference. Derived from a suggestion by Bruce Korb.
5401 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
5403 * doc/autoconf.texi (config.status Invocation): Warn about
5404 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
5405 * doc/install.texi (Defining Variables): Likewise.
5406 Based on a proposed patch by Ralf Wildenhues.
5408 * man/Makefile.am (.x.1): Make sure the required generated files
5409 are up to date. Problem and original solution proposed by Stepan Kasal.
5410 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
5411 implicit-man-prerequisites): New rules, used by the above.
5413 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.
5414 * config/config.guess, config/config.sub, config/install-sh: Likewise.
5415 * config/missing, config/texinfo.tex: Likewise.
5417 2005-01-29 Stepan Kasal <kasal@ucw.cz>
5419 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5420 Update the long comment explaining it.
5422 m4_require no longer writes an ``is required by'' line to the
5423 execution stack. It contains only one bit of non-redundant
5424 information: that the macro was required, not called. And even
5425 this bit is useless in most situations: have you ever met a macro
5426 which both calls and requires the same macro?
5428 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...

5848 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5849 "char c = '\200';" rather than "char c = 0x80;" as the

5890 2004-11-23 Stepan Kasal <kasal@ucw.cz>
5892 * doc/autoconf.texi (Pretty Help Strings): Fix quoting issues
5893 with the examples; fix the bug in MY_ARG_WITH example reported
5894 by Alexandre Duret-Lutz.
5895 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_ENABLE): Enable
5896 expansion of $1 in the comment emitted to configure.

5906 * doc/autoconf.texi (Autoconf Language): Explain that
5907 ``descriptions'' may not be double quotes.
5908 (Quotation Rule Of Thumb): Likewise.
5909 (Pretty Help Strings): Likewise; remove the wrong comment;
5910 simplify the examples and improve their quoting.
5912 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5914 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5915 the $1_found variable, don't test whether the file is executable;
5916 Both things are checked ...
5917 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
5918 the former ``test -f''.
5919 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
5921 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
5923 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
5924 use cp -R instead.
5926 2004-11-10 Derek R. Price <derek@ximbiot.com>
5928 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
5929 limitations. Reorder paragraphs for clarity.
5931 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
5933 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
5934 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
5935 variants", "Unix", and some related minor wording fixups.
5937 (Shellology, Special Shell Variables): Document that the Zsh
5938 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
5939 to Alexandre Duret-Lutz for this info.

5950 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
5952 * doc/autoconf.texi (auindex): New macro.
5953 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
5954 Problem reported by Stepan Kasal.
5956 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5958 Fix problems reported by Andreas Buening in:
5959 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
5960 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5961 in test makefile.
5962 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
5963 readable; it's not true in OS/2-emx.
5965 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5967 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5968 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5969 (trivial change). Problem and patch reported by Andrew Church in:
5970 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5972 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5974 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
5975 three args in examples. Problem reported by Frederik Fouvry in:
5976 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
5977 Also, fix some minor spacing and punctuation bugs.
5979 2004-09-02 Akim Demaille <akim@epita.fr>
5981 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
5982 "case" to restore ordering.
5983 Reported by Stepan Kasal.
5985 2004-08-26 Akim Demaille <akim@epita.fr>
5987 * doc/autoconf.texi: Minor typos and stylos.

5993 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
5995 Version 2.59b.
5997 * README: Add advice about m4 1.4.2.
5999 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
6000 texinfo.tex for now (done by hand now).
6001 * Makefile.maint (wget_files, cvs_files):
6002 Remove ansi2knr.c; nobody uses it.
6003 (ansi2knr.c-url_prefix): Remove.
6004 (cvs-update): Fix test for failure. I don't know why it ever
6005 worked...
6007 * doc/autoconf.texi: Update URLs, some of which went stale.
6008 Use @uref rather than @href.
6010 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
6011 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
6013 * config/config.guess, config/config.sub, config/elisp-comp,
6014 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
6015 doc/fdl.texi, doc/standards.texi: Sync with master copy.
6017 * NEWS, TODO, configure.ac, bin/autoscan.in,
6018 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
6019 doc/install.texi, lib/Autom4te/Configure_ac.pm,

6023 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
6024 tests/tools.at, tests/torture.at:
6025 Use "file name" rather than "filename" or "path",
6026 to be consistent with the terminology of the GNU coding standards.
6028 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
6030 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
6031 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
6032 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
6033 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
6035 More fixes to support spaces in the name of the build directory.
6036 This isn't a complete fix but it's an improvement.
6038 * bin/autoconf.as (autom4te_options): New var.
6039 Use it instead of appending to AUTOM4TE, so that we can allow
6040 spaces in the build directory's absolute name.
6041 * bin/autoheader.in ($autoconf): Allow spaces in file names.
6042 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
6043 AT_CHECK_NOESCAPE): Likewise.
6044 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
6045 main program): Likewise.
6047 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
6049 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
6050 From Ralf Corsepius in:
6051 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
6053 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
6055 * doc/autoconf.texi (Function Portability): Document isinf and
6056 and isnan. From a suggestion by Kevin Ryde.
6058 * lib/Autom4te/General.pm (END): Return correct exit status even
6059 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
6061 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
6063 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6064 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6065 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
6067 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6069 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
6070 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
6071 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
6072 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
6073 * lib/autom4te.in (Automake-preselections): Preselect
6074 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6076 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6078 * lib/autom4te.in (Automake-preselections): Preselect
6079 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6080 trace them.
6082 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6084 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6085 Tru64.
6086 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6087 Document problem with "`""`" in pdksh POSIX mode.
6089 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6091 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6092 with pdksh, too. Problem reported by Patrick Welche via
6093 Gary V. Vaughan.
6094 * doc/autoconf.texi (Shellology): Note that set -o posix is
6095 useful for pkdsh, too.
6097 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6099 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6100 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6101 Don't fail if ENV or BASH_ENV is readonly.
6102 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6103 etc. are read only. Problem reported by Ludovic Courtes.
6105 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6107 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6108 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6109 (trivial change)
6111 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6113 * doc/autoconf.texi (File System Conventions): Warn about
6114 names like "aux". Problem reported by Eric Blake.
6116 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6117 by zero instead of array size, so that we can use any arithmetic
6118 constant expression (instead of requiring an integer constant
6119 expression). This allows us to test expressions like DBL_MAX <
6120 LDBL_MAX, which didn't conform to the C standard using the old
6121 method.
6122 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6123 now that we can do floating-point tests at compile time.
6125 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6127 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6128 and LDBL_EPSILON, as the resulting expression isn't an
6129 integer constant expression and violates the C standard.
6130 Problem reported by Nelson H. F. Beebe. Also, check
6131 for "L" suffix, and check that long double doesn't have
6132 worse range or precision than double, that mixed-mode
6133 arithmetic doesn't generate a diagnostic, that double
6134 constants fit in long double.
6136 2004-06-03 Kevin Ryde <user42@zip.com.au>
6138 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6139 malloc(0) and realloc(NULL,size).
6141 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6142 Bob Proulx.
6144 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6146 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6147 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6148 by Jim Meyering.
6150 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6152 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6153 can be rewritten using if-then-else. Suggested by Bruno Haible.
6155 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6157 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6158 Problem reported by Stepan Kasal.
6160 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6162 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6163 change). Patch reported by Ralf Wildenhues in
6164 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6166 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6167 function F exists if the compiler and linker let you compile an
6168 expression like (F != 0). Recent versions of GCC optimize away
6169 the reference to F in that case, since every function address must
6170 be nonzero, so the link succeeds even if F does not exist.
6171 Problem reported by Manu in
6172 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6174 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6175 "Unix". Many uses changed.
6176 (Limitations of Builtins): Explain better why the ! command isn't
6177 portable.
6179 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6181 * lib/autom4te.in (Automake-preselections): Preselect
6182 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6184 2004-05-19 Kevin Ryde <user42@zip.com.au>
6186 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6187 referencing AC_FUNC_STRERROR_R.
6189 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6190 note pessimistic assumption when cross compiling.
6192 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6194 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6195 (until 2004) invoked subcommands with sh -e, contra POSIX.
6196 Reported by Kevin Ryde.
6198 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6200 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6201 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6202 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6203 `test -f " /usr/bin/grep"', which _always_ failed.
6204 (AC_PROG_SED): Ditto bogus PATH fix.
6205 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6206 requires that grep correctly supports _multiple_ `-e' options, rather
6207 than stating only that grep should accept `-e'.
6209 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6211 Port to C99, which requires that 'exit' be declared.
6213 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6214 to ensure that stdlib.h is included.
6215 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6216 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6217 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6218 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6219 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6220 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6221 when using 'exit' in a test; C99 requires that 'exit' be declared.
6223 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6225 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6226 now prefers 'grep' implementations that accept -e.
6227 (Limitations of Usual Tools): Describe problems of traditional
6228 egrep and fgrep with long input lines, and of traditional grep
6229 with -e.
6230 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6231 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6232 All callers changed. Append /usr/xpg4/bin to the PATH, for
6233 Solaris.
6234 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6235 the user with complaints about multiple -e options.
6236 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6237 Define it with AC_PROG_GREP.
6238 * configure.ac (AC_PROG_GREP): Add.
6239 * lib/freeze.mk (GREP): New macro.
6241 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6243 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6244 a possible candidate only after all others fail, rather than
6245 consulting it first. This improves backward compatibility by
6246 better reflecting the way shell selection occurred in previous
6247 versions of Autoconf, and should help to avoid triggering latent
6248 problems in other packages, such as the one in Automake where zsh
6249 is not handled robustly:
6250 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6251 Although it is not Autoconf's responsibility to work around
6252 problems in Automake, it nevertheless makes sense to avoid
6253 introducing unnecessary incompatibilites.
6255 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6256 Gary V. Vaughan <gary@gnu.org>
6258 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6259 how deeply nested we are when a suitable tool is found, set the
6260 ac_path_TOOL_found flag.
6261 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6262 nested we are in this macro. Break out of all 3 nested loops if
6263 ac_path_TOOL_found is set.
6265 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6267 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6268 of the _AS_PATH_WALK loop too if GNU flavor is found.
6270 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6272 * doc/autoconf.texi (Limitations of Make): Update documentation
6273 for `$<'. New entry `Long lines', based on a report from Simon
6274 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6275 paragraph about DJGPP, based on a mail from Richard Dawe.
6277 2004-04-20 Paul Eggert <eggert@twinsun.com>
6279 * tests/c.at (C keywords): Don't assume that GCC supports
6280 "restrict" and "inline", as sufficiently-old GCC versions do not
6281 (also, GCC configured to be in pedantic C89 mode does not).
6282 Problem reported by Sumit Pandya in:
6283 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6285 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6286 consider -g to work if it generates warnings when plain compiles
6287 don't. Problem reported by Braden McDaniel in:
6288 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6290 * doc/autoconf.texi (Slashes): New section, to document a problem
6291 reported by Jim Meyering in:
6292 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6294 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6295 linker output files before linking, to work around IRIX 6 linker bug.
6296 Problem reported by Rainer Orth in:
6297 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6299 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6301 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6302 best tool so far counter rely on the tool path variable name to
6303 avoid checks for one tool being affected by the results of running
6304 the length check on a previous tool.
6306 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6307 match expression argument, as different greps have different
6308 regular expression flavours.
6309 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6310 literals.
6311 (AC_PROG_EGREP): Pass 'EGREP$'.
6312 (AC_PROG_GREP): Pass 'GREP$'.
6314 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6316 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6317 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6319 2004-03-29 Paul Eggert <eggert@twinsun.com>
6321 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6322 Types, Specific Compiler Characteristics, System Services,
6323 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6324 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6325 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6326 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6327 Likewise.
6328 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
6329 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
6330 AC_TYPE_OFF_T): Likewise.
6331 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
6332 Likewise.
6334 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to

6341 HAVE_STRUCT_TM_TM_ZONE is not defined.
6342 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6343 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6344 for HAVE_TZNAME.

6390 behavioral changes.
6391 * tests/mktests.sh: Do not generate tests for the
6392 new macros.
6393 * NEWS: Document these changes.
6395 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6396 they make TeX hang up.

6401 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6402 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than

6418 2004-02-23 Gary V. Vaughan <gary@gnu.org>
6420 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
6421 from the next generation of Libtool.
6422 * lib/autom4te.in (Autoreconf-preselections): Ditto.
6424 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6426 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
6427 is not always thread-safe. Report from Nathanael Nerode.
6429 2004-02-18 Paul Eggert <eggert@twinsun.com>
6431 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6432 problem on QNX reported by Stephen Rasku in
6433 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6435 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6436 $(m4sh_m4f_dependencies); this removes a FIXME.
6437 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6438 (MAINTAINERCLEANFILES): Split into pieces,
6439 one per related section. Add $(srcdir)/wrapper.in.

6444 AC_SUBST provides no portable way to escape literal newlines.
6446 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6447 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6448 Darwin uses -lcrt2.o and there's little point to cataloging all
6449 the system variants. Partial fix reported by Andreas Waechter in:
6450 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
6451 for bug reported by Nelson H. F. Beebe in:

6466 the behavior of the third argument.
6467 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6468 correctly the behavior of the third argument. Document
6469 what the three macros that AU_DEFUN defines do. Fix
6470 warning message when the third argument includes $0

6473 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6474 Eric Sunshine <sunshine@sunshineco.com>
6475 Paul Eggert <eggert@twinsun.com>
6477 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

6479 parameter. Expand _AS_SHELL_FN_SPY.
6480 (AS_INIT_WITH_SHELL_FN): Removed.
6481 (_AS_SHELL_FN_SPY): New macro.
6482 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
6483 macros.
6484 (AS_SHELL_SANITIZE): Remove loop to find better shell
6485 and documentation for the parameter.
6486 (_AS_DETECT_BETTER_SHELL): Move it here.

6488 (_AS_RUN): Move it here, support testing with eval.
6489 (AS_REQUIRE_SHELL_FN): Require shell functions when
6490 it is used.
6491 (_AS_LINENO_WORKS): Put around braces, we do not
6492 trigger the bash bug anymore.
6493 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
6494 use AS_INIT_WITH_SHELL_FN.
6495 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6497 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6499 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

6501 is broken.
6502 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
6503 (AU_DEFUN): Honor the third parameter, create autoupdate
6504 macros with AU_DEFINE.
6505 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
6506 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

6508 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
6509 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

6525 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6526 2003 (except 1997) to the list of copyright years. This undoes
6527 the 2003-05-22 change, which removed the older years from the list.
6528 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6530 2004-01-27 Gary V. Vaughan <gary@gnu.org>
6531 Albert Chin-A-Young <china@thewrittenword.com>

6541 _AC_PROG_GREP, and AC_PROG_SED.
6542 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6543 longest input length accepted by a command.
6544 (AC_PROG_SED): Use it.
6545 * doc/autoconf.texi (Particular Programs): Document the changes.
6546 * NEWS: Updated.
6548 2004-01-27 Paul Eggert <eggert@twinsun.com>
6550 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

6555 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6556 bin/autoconf.in, config/Makefile.in, config/config.guess,
6557 config/config.sub, config/install-sh, config/mdate-sh,

6570 sources.
6572 2004-01-26 Paul Eggert <eggert@twinsun.com>
6574 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6575 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6576 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6577 not <inttypes.h>. Problem reported by Tim Mooney in
6578 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6579 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6580 Likewise.
6582 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6583 otherwise "make check" fails because it forbids cmp (I guess
6584 because cmp treats files as binary on DOS-like systems).
6586 * tests/mktests.sh: Update copyright date to 2004, since some tests
6587 have changed in 2004.
6589 2004-01-23 Gary V. Vaughan <gary@gnu.org>

6592 non-truncating sed or gsed program in PATH.
6593 * tests/acprograms.at: Add it.
6594 * doc/autoconf.texi (Particular Programs): Document it.
6595 * NEWS: Updated.
6597 2004-01-15 Paul Eggert <eggert@twinsun.com>
6599 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6600 -std1 disables some useful extensions on Tru64. Problem reported
6601 by N. Lichtmaier in
6602 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6604 2004-01-14 Paul Eggert <eggert@twinsun.com>
6606 * doc/autoconf.texi (Programming in M4sh): Document that
6607 AS_MKDIR_P succeeds if the destination is a symbolic link
6608 to an existing directory.
6609 (Limitations of Usual Tools): Note that mkdir -p might not
6610 succeed on symlinks to directories.
6612 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6614 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6615 * bin/autoheader.in: Grammar fix in message.
6616 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6617 Test for dir before calling mkdir -p. (trivial changes)
6619 2004-01-13 Eric Blake <ebb9@byu.net>
6621 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6622 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6624 2004-01-10 Jim Meyering <jim@meyering.net>
6626 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6628 2004-01-09 Paul Eggert <eggert@twinsun.com>
6630 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6631 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6632 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6633 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6634 AC_COMPILE_IFELSE, since we now assume our caller invokes
6635 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6636 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6637 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6638 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6640 2004-01-07 Paul Eggert <eggert@twinsun.com>
6642 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6643 `"'...'"`, as it's confusing (and I suspect it may not work on
6644 some platforms). The code was incorrect anyway, as it assumed
6645 that \$ evaluated to itself in that context. Reported by
6646 Alexandre Duret-Lutz.
6648 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6650 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6651 and _LT_AC_TAGCONFIG.
6653 2004-01-06 Paul Eggert <eggert@twinsun.com>
6655 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6656 example, and add more examples. Reported by Eric Sunshine.
6658 2004-01-05 Paul Eggert <eggert@twinsun.com>
6660 * doc/autoconf.texi (Limitations of Usual Tools):
6661 Remove warning against "rm -fr" introduced yesterday; it
6662 was a false alarm.
6664 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6665 autoscan, autoupdate, ifnames): Don't use chmod -w.
6666 * lib/Makefile.am (autom4te.cfg): Likewise.
6667 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6668 "chmod -w".

6676 2004-01-04 Paul Eggert <eggert@twinsun.com>
6678 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6679 Use "rm -f" to remove conftest.sed, not plain "rm".
6680 Bug reported by David Relson in
6681 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6683 * Makefile.am (autom4te-update):
6684 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6685 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6686 * doc/autoconf.texi (Guidelines): Likewise.
6687 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

6694 srcdir): Likewise.
6695 * doc/autoconf.texi (Limitations of Usual Tools):
6696 Warn against "rm -fr".

6700 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6701 -c -o might not work. From a suggestion by Kevin Ryde.
6702 (C Compiler, Generating Sources, Limitations
6703 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6704 Don't put '-o' after non-options, as POSIX doesn't allow this.
6705 Mention that cc's name might be gcc or c89 or whatever.
6707 2004-01-04 Kevin Ryde <user42@zip.com.au>
6709 * doc/autoconf.texi: Add various further index entries.
6711 2003-12-29 Paul Eggert <eggert@twinsun.com>
6713 * bin/autoreconf.in (autoreconf_current_directory):
6714 Fix typo: mkdir without umask arg.
6716 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6718 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6719 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6720 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6721 explanation clearer.
6723 2003-12-24 Andreas Schwab <schwab@suse.de>
6725 * doc/autoconf.texi (Default Includes): Fix misspelling of
6726 AC_INCLUDES_DEFAULT.

6730 * configure.ac: Test if sh -n works.
6731 * configure: Regenerate.
6732 * tests/atlocal.in: Store the result here.
6733 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6734 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6735 of explicitly testing.
6736 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6737 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6738 * tests/tools.at (Syntax of the shell scripts): Simplify
6739 using AT_CHECK_SHELL_SYNTAX.
6740 (Syntax of the Perl scripts): Remove definition of
6741 AT_CHECK_PERL_SYNTAX.
6743 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6745 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
6746 stderr to /dev/null.

6753 Extracted from AS_SHELL_SANITIZE.
6754 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6755 macros.
6756 (AS_SHELL_SANITIZE): Move reinvocation code from
6757 _AS_LINENO_WORKS, use it to find out if shell
6758 functions work.
6759 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6760 does not work.
6761 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6762 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

6773 (&sizes): New.
6774 Use them.

6849 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

6984 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
6985 cross test.
6987 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
6989 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
6990 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

7002 Problems reported by Eric Sunshine.
7004 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7006 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7007 -mGLOB_options_string stuff for Intel ifc, which can cause

7031 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7032 cache variable instead of $G77 to decide whether to include -O2,
7033 since $G77 is specific to Fortran 77.

7037 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

7042 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7043 arguments so that it can be used with syntax identical to
7044 AC_PROG_F77, and so that we can more easily decide to
7045 remove/deprecate the DIALECT optional argument in the future if it
7046 proves troublesome.
7047 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7048 non-freeform-supporting compilers. Document freeform flags.
7050 2003-10-03 Akim Demaille <akim@epita.fr>
7052 * configure.ac: Look for emacs, not macs.

7055 2003-10-03 Akim Demaille <akim@epita.fr>

7062 2003-10-03 Akim Demaille <akim@epita.fr>
7064 * configure.ac: Quotation and formatting changes.

7099 have been created when invoking the compiler.

7113 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7114 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7115 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7117 2003-09-26 Akim Demaille <akim@epita.fr>
7119 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7120 directory for AC_CONFIG_COMMANDS' first argument exists.
7121 This makes valid the invocation of _AC_SRCPATH that follows.
7122 Reported by Eric Sunshine.
7123 * doc/autoconf.texi (Configuration Commands): Adjust.
7125 2003-09-26 Akim Demaille <akim@epita.fr>
7127 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7128 Reported by Ralf Corsepius.
7130 2003-09-26 Akim Demaille <akim@epita.fr>
7132 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
7133 arguments.

7144 2003-09-26 Akim Demaille <akim@epita.fr>
7146 The test suite are sometimes assigning timings incorrectly.
7147 Reported by Henk Krus.
7148 Diagnosed by Nicolas Joly.
7150 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7151 AT_help_all.
7152 Instead of making AT_help a sequence of assignments to grow
7153 $at_help_all, just make AT_help_all be the growing contents of
7154 $at_help_all, and make a single assignment in...
7155 (AT_INIT): here.
7156 (at_times_skip): Flip the meaning and rename as...
7157 (at_times_p): this.
7158 (AT_INIT): When summarizing the test that ran, remove
7159 $at_times_file after use, and check it is present before trying to
7160 use it.

7168 (ifnames): chmod -w.
7169 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7170 executables, not bin/ executables! Otherwise all the magic needed
7171 to find non installed files is turned off. This caused a failure
7172 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7173 as found in its environment (sent by tests/autoreconf): pointing
7174 to bin/autom4te that could not find its files.
7175 * tests/mktests.sh: Force the replacement of generated files, for
7176 the sake of "mv" program that are interactive when overwriting a
7177 -w file.

7186 Paul Eggert <eggert@twinsun.com>
7188 Trivial change to support GCC's configuration procedure.
7189 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
7190 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
7191 about inconsistency if the preprocessor is set to give errors for
7192 any warning.

7195 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

7211 2003-09-12 Akim Demaille <akim@epita.fr>
7213 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
7214 not asm/types.h.
7216 2003-09-11 Akim Demaille <akim@epita.fr>
7218 * doc/autoconf.texi (Header Portability): linux/random.h.
7219 From Peter Hendrickson.
7221 2003-09-10 Akim Demaille <akim@epita.fr>
7223 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
7224 willing to edit the output files.
7226 2003-09-10 Akim Demaille <akim@epita.fr>
7228 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
7229 and AC_FC_FREEFORM.
7230 * tests/mktests.sh: Skip AC_FC_SRCEXT.
7231 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
7233 2003-09-09 Akim Demaille <akim@epita.fr>

7247 Improve the accuracy of the wording about obsolescence.
7248 From a suggestion by Ian Lance Taylor in
7249 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
7251 2003-09-05 Paul Eggert <eggert@twinsun.com>
7253 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
7254 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
7256 2003-09-04 Akim Demaille <akim@epita.fr>
7258 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
7259 AC_FUNC_WAIT3.
7261 2003-09-04 Akim Demaille <akim@epita.fr>
7263 * bin/autom4te.in: Use &fatal where more appropriate than &error.
7264 (freeze): When exiting, use $exit_code.

7271 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7273 Add support for newer Fortran dialects. The F77 interface is
7274 unchanged, and continues to support Fortran 77. New FC macros
7275 correspond to all the old F77 macros, with output variables FC,
7276 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7277 available dialect, but older dialects can be specified. There are
7278 new macros AC_FC_SRCEXT to set the source extension, and
7279 AC_FC_FREEFORM to accept free-form source files.
7281 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
7282 New macros.
7283 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
7284 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
7285 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
7286 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

7293 AC_FC_DUMMY_MAIN, _AC_FC_MAIN, AC_FC_MAIN, __AC_FC_NAME_MANGLING,
7294 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
7295 AC_FC_SRCEXT, AC_FC_FREEFORM):
7296 New macros.
7297 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
7298 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
7299 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
7300 Rewrite in terms of the above.
7301 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
7302 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
7303 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
7304 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
7306 2003-09-02 Paul Eggert <eggert@twinsun.com>
7308 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
7309 Document problems with timestamp resolution that 'make', 'cp -p', and
7310 'touch -r' have.
7312 2003-08-27 Akim Demaille <akim@epita.fr>
7314 * tests/m4sugar.at (cross_warning): Make sure to enable the
7315 output, so that we can track spurious m4sugar output.
7316 * tests/local.at: Require 2.57.
7317 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7318 are defaulted by AT_CHECK anyway.
7319 Use AT_CHECK_AUTOM4TE.
7320 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7321 missing dnl.
7323 2003-08-27 Akim Demaille <akim@epita.fr>
7325 * bin/autoheader.in: Issue the "Using auxiliary..." message only
7326 when -Wobsolete is set.
7327 Set it on by default.
7328 Suggested by Klee Dienes.
7330 2003-08-27 Akim Demaille <akim@epita.fr>
7332 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
7333 documentation.
7334 From Guido Draheim.
7336 2003-08-26 Akim Demaille <akim@epita.fr>
7338 * doc/autoconf.texi (Output): Make clear that one can run code
7339 after AC_OUTPUT.
7341 2003-08-25 Akim Demaille <akim@epita.fr>
7343 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
7344 CVS Bison.
7346 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>

7358 * configure.ac: Bump to 2.57c.
7360 2003-08-22 Akim Demaille <akim@epita.fr>
7362 Version 2.57b.
7364 * Makefile.cfg (local-checks-to-skip): New.
7365 * Makefile.maint (local-check): Rename as...
7366 (local-checks-available): this.
7367 (local-check): New.
7369 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
7370 * configure.ac: Require Automake 1.7.6.
7372 2003-08-22 Akim Demaille <akim@epita.fr>
7374 Output stack traces in warnings.
7376 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
7377 Replace the former...
7378 (m4_warn): Pass the call stack to _m4_warn.
7379 * bin/autom4te.in: Adjust to output the call stack.
7380 * tests/m4sugar.at (m4@&t@_warn): Adjust.
7382 2003-08-22 Akim Demaille <akim@epita.fr>
7384 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
7385 * bin/autom4te.in: Adjust.
7387 2003-08-21 Akim Demaille <akim@epita.fr>
7389 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7390 (&verbose): Remove.
7391 (&getopt): Adjust the note and verb channels, depending upon
7392 --verbose.
7393 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
7394 * bin/autoupdate.in: Adjust.
7395 Use &verb, not &verbose.
7397 2003-08-21 Akim Demaille <akim@epita.fr>
7399 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7400 &parse_WARNINGS.
7401 ($help): Use Autom4te::ChannelDefs::usage.
7402 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7403 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7405 2003-08-21 Akim Demaille <akim@epita.fr>
7407 First stab at preserving warnings between calls to autom4te,
7408 including when the cache is used.
7410 There are still several issues: (i) there are too many runs of m4
7411 (one for include, one for warnings, and some more), (ii) warnings
7412 spreading on several lines are not handled gracefully, (iii) the
7413 code meant to have the call stack display for errors does not work
7414 (its handling should move from m4 to autom4te).
7416 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7417 Use them.
7418 (@preselect): Add m4_warn.
7419 ($exit_status): Remove, use $exit_code.
7420 ($help): Use Autom4te::ChannelDefs::usage.
7421 (&handle_m4): No longer define the m4_warnings.
7422 At each run, extract and report the warnings.
7423 Always cache the result, including if the exit status is on
7424 failure, since if nothing changes, we should result in the same
7425 failure, hence we can use the cache.
7426 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7427 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7428 Remove.
7429 (m4_warn): Redefine as a do-nothing: it is its invocation that
7430 matters, as warnings are now reported via traces.
7431 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7432 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7433 the latter reveals calls to the former.
7435 Adjust the tests.
7437 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7439 2003-08-21 Akim Demaille <akim@epita.fr>
7441 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7442 Use them.
7444 2003-08-21 Akim Demaille <akim@epita.fr>
7446 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7447 forward order.
7448 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7449 (&parse_warnings): Accept a list of warning requests.
7450 (&usage): Return a string, not a side effect.
7451 (cross): New warning category.
7453 2003-08-21 Akim Demaille <akim@epita.fr>
7455 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7456 (&require_configure_ac): Accept an optional directory argument.
7457 ($configure_ac): Remove.
7458 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7459 (&catfile): Remove.
7460 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7461 * bin/autoscan.in: Adjust.
7463 2003-08-20 Akim Demaille <akim@epita.fr>
7465 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7466 Reported by Alexandre Duret-Lutz.
7468 2003-08-20 Akim Demaille <akim@epita.fr>
7470 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7471 * bin/autom4te: Adjust.
7472 In particular, be Autoconf tools are really silent when properly
7473 working, bind the verbosity of the 'note' channel to $verbose.
7474 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7475 (&xsystem, &contents): Remove, since they are exported by...
7476 * lib/Autom4te/FileUtils.pm: this.
7477 More perldoc.
7478 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7479 * lib/Autom4te/FileUtils.pm: here.
7481 2003-08-20 Akim Demaille <akim@epita.fr>
7483 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7484 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
7485 from CVS Automake.
7487 2003-08-20 Akim Demaille <akim@epita.fr>
7489 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
7490 (autom4te-update): New.
7491 * Makefile.cfg (update): Bind autom4te-update.
7493 2003-08-19 Derek Price <derek@ximbiot.com>
7495 * lib/autotest/general.m4: Comment various HELP_* diversions.
7496 (PARSE_ARGS_BEGIN): New section for option parsing related
7497 initialization.
7498 (AT_ARG_OPTION,AT_ARG_OPTION_ARG,_AT_ARG_OPTION): New macros to define
7499 package specific options and associated help.

7503 * config/announce-gen, Makefile.cfg: New.
7504 * Makefile.am: Adjust.
7505 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
7507 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7509 * lib/autom4te.in (Automake-preselections): Preselect
7510 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
7511 and m4_sinclude.
7513 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7515 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
7516 (Autoconf-without-aclocal-m4): ... this new language.
7517 * doc/autoconf.texi (autom4te Invocation): Mention
7518 Autoconf-without-aclocal-m4.

7522 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
7523 RUN-IF-PASS optional arguments.
7525 2003-08-18 Derek Price <derek@ximbiot.com>

7532 STDOUT & STDERR arguments.
7534 2003-08-14 Derek Price <derek@ximbiot.com>
7536 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7537 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7538 shorter column three. Add DESCRIPTION to log file content.
7540 2003-08-13 Derek Price <derek@ximbiot.com>
7542 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7543 output.
7545 2003-08-12 Derek Price <derek@ximbiot.com>
7547 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7548 (AT_CHECK_NOESCAPE): Move core functionality to...
7549 (_AT_CHECK): ...this new macro.
7551 2003-08-07 Derek Price <derek@ximbiot.com>
7553 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7554 (AT_CHECK_NOESCAPE): ...to this new macro.
7556 2003-07-31 Paul Eggert <eggert@twinsun.com>
7558 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7559 in Bash 2.01. Problem reported by Brian Gough in
7560 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7562 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7564 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7565 -lcrt1.o, for OS X. (trivial change)
7567 2003-07-07 Paul Eggert <eggert@twinsun.com>
7569 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7570 inside '#ifndef __cplusplus'. Problem reported by
7571 Bob Friesenhahn.
7573 2003-07-06 Bill Clarke <llib@computer.org>
7575 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7576 'long', not 'int', for benefit of Sun's recent C++ compilers
7577 (trivial change). See:
7578 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7579 (This really should be 'intptr_t', not 'long', but that would
7580 take more work.)
7582 2003-06-25 Akim Demaille <akim@epita.fr>
7584 * lib/Makefile.am (autom4te.cfg): Make it read only.
7585 Depend on Makefile since it contains substitutions.
7586 From Paolo Bonzini.
7587 * lib/autom4te.in (args): Add local.at? for Autotest args.
7588 This change was made on autom4te.cfg which is generated.
7589 Reported by Raja R. Harinath.
7591 2003-06-25 Akim Demaille <akim@epita.fr>
7593 * doc/autoconf.texi (Header Portability): sys/mount.h.
7594 From Gareth McCaughan.
7596 2003-06-23 Akim Demaille <akim@epita.fr>
7598 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7599 not all of them. This fixes 1. the fact that when testing
7600 Autoconf there are many many config.log, 2. the incorrect use of
7601 top_srcdir to find config.log.
7602 Don't mix the detailed output of failed test with the summary of
7603 failures. Rather, append detailed log afterwards.
7605 2003-06-23 Akim Demaille <akim@epita.fr>
7607 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7608 always run: output config.log on $at_group_log.
7610 2003-06-23 Akim Demaille <akim@epita.fr>
7612 * tests/torture.at (#define header templates): Don't use quotes in
7613 C++ comments as it puzzles Emacs' sh font-lock-mode.
7615 2003-06-23 Akim Demaille <akim@epita.fr>
7617 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7618 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7619 * tests/atspecific.m4: Rename as...
7620 * tests/local.at: This.
7621 * tests/suite.at: Move the globals into...
7622 * tests/local.at: here.
7623 * tests/Makefile.am: Adjust.
7624 * doc/autoconf.texi (testsuite Scripts): Adjust.
7626 2003-06-21 Kevin Ryde <user42@zip.com.au>
7628 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7629 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7630 ensuring we add -std1 for full-ANSI.
7632 * doc/autoconf.texi (hdrindex): New macro.
7633 Add index entries for portability of various standard header files.
7635 2003-06-20 Akim Demaille <akim@epita.fr>
7637 * configure.ac: Bump to 2.57b.
7639 2003-06-20 Akim Demaille <akim@epita.fr>
7641 Version 2.57a.
7643 2003-06-20 Akim Demaille <akim@epita.fr>
7645 * bin/autom4te.in: Don't rely on $HOME being defined.
7646 Reported by Marc Espie as PR/233.
7648 2003-06-20 Akim Demaille <akim@epita.fr>
7650 * lib/autotest/general.m4: Use at_times_file only if used.
7651 From Nicolas Joly.
7653 2003-06-20 Akim Demaille <akim@epita.fr>
7655 * config/config.guess, config/config.sub, config/elisp-comp,
7656 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7657 Update from masters.
7659 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7661 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7662 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7663 (TEST_SCRIPT): New diversion.
7664 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7665 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7666 (AT_INIT): Support for expected failures.
7668 2003-06-02 Akim Demaille <akim@epita.fr>
7670 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7671 changes.
7672 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7673 Autoconf nor Automake.
7674 (&contents): New, from Automake.
7675 PODify.
7677 2003-05-28 Paul Eggert <eggert@twinsun.com>
7679 * NEWS, doc/autoconf.texi (Particular Functions),
7680 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7681 is the inverse of localtime.
7683 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7685 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7686 (handle_exec_errors): New function. Work around $! being
7687 altered by WEXITSTATUS.
7688 (xqx, xsystem): Use handle_exec_errors.
7690 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7692 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7693 Do not call `_exit()', simply modify `$?'.
7694 (xsystem): Reset $! before running system, and check it afterward.
7695 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7696 63 for version mismatches.
7698 2003-05-23 Akim Demaille <akim@epita.fr>
7700 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7701 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7702 the middle of a line).
7703 * lib/m4sugar/m4sugar.m4: Likewise.
7704 Remove useless spaces in comments.
7706 2003-05-23 Akim Demaille <akim@epita.fr>
7708 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7709 exit 63, so that we (or Automake's "missing") can tell the
7710 difference with a plain failure.
7711 * doc/autoconf.texi (Notices): Adjust.
7713 2003-05-23 Akim Demaille <akim@epita.fr>
7715 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7716 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7717 White spaces cleanup.
7719 2003-05-22 Jim Meyering <jim@meyering.net>
7720 Paul Eggert <eggert@twinsun.com>
7722 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7723 Remove `#include <stdlib.h>' from the list; we should never
7724 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7725 resulting namespace pollution would cause other tests to fail.
7726 Configure scripts run with some older versions of g++ and HP's
7727 aCC would fail due to such an #include. Problems reported by
7728 Matthew Mueller in <http://bugs.debian.org/120704> and by
7729 Keith Bostic in
7730 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7731 In the test, use the test declaration before including <stdlib.h>,
7732 as that's closer to how it'll be used.
7734 2003-05-23 Akim Demaille <akim@epita.fr>
7736 * doc/autoconf.texi (Header Portability): ucred.h.
7737 From Ian Redfern.
7739 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7741 Overhaul Autotest's logging: generate separate log files
7742 in testsuite.dir/NNN/testsuite.log, and append them to
7743 testsuite.log instead of re-running the test verbosely.
7745 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7746 file descriptor, write 0 to at_status_file instead of setting
7747 at_status=0, initialize some new variables (at_status_file,
7748 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7749 to rerun the tests, instead append the at_group_log to the
7750 at_suite_log when a test fails.
7751 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7752 with the AS_MESSAGE_LOG_FD redirected to stdout.
7753 (AT_CLEANUP): save the output status in $at_status_file
7754 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7755 its original place.
7756 (AT_CHECK): since tests are run with a redirected stdout,
7757 and used to be re-run in verbose mode, turn some $at_verbose
7758 into echo, and don't redirect the output of testing stdout
7759 and stderr.
7761 * lib/autotest/autoconf.texi (testsuite Scripts): Update

7880 and truncate.
7882 2003-05-06 Akim Demaille <akim@epita.fr>
7884 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7885 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7886 by aclocal.m4 is changed it might require the importing of another
7887 m4 extension file, i.e., aclocal must be run.
7889 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7890 (&parse_args): Use --force with aclocal if required and supported.

7900 open during the whole autom4te run.
7901 ($icache_file): New.
7902 (&freeze): Lock the $icache_file.
7904 2003-04-29 Derek Price <derek@ximbiot.com>
7906 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7907 seperator with m4_append_uniq(). It doesn't work.
7908 (AT_CLEANUP): Add `;' to end of at_help_all.
7909 (AT_INIT): Allow --keywords to be specified more than once. When
7910 grepping $at_help_all for keywords, use the field and keyword

7912 to support the new --keywords behavior.
7914 2003-04-27 Karl Berry <karl@freefriends.org>
7916 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7917 align better with others. I also made some of the individual
7918 entries on one line, for brevity and to make it easier for me to

8143 gettimeofday and many other functions.
8145 2002-12-03 Paul Eggert <eggert@twinsun.com>

8157 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8159 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8160 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8161 defined, to support freestanding compilers. This should fix the
8162 bug reported by Momchil Velkov in
8163 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8165 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

8201 * Makefile.maint: Sync with Bison, i.e.:
8202 (po-check): Scan .l and .y files instead of the
8203 .c and the .h files that they generate. This fixes the bug
8204 reported by Tim Van Holder in:

8206 Look for N_ as well as for _. Try to avoid matching #define for

8239 Makefile.in if Makefile.am exists.

8263 2002-11-05 Akim Demaille <akim@epita.fr>
8265 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8266 Remove.
8267 We _have_ to stop using the old compatibility scheme that tried to
8268 avoid useless backslashes because Libtool 1.4.3 contains a
8269 AC_DEFINE([error_t], [int],
8270 [Define to a type to use for \`error_t' if it is not
8271 otherwise available.])
8272 We _have_ to quote the single quote and backslashes with \. The
8273 old compatibility scheme saw that ` was backslashed, and therefore
8274 did not quote the single quote. Hence before this patch, Autoconf
8275 was not compatible with Libtool.
8277 2002-11-04 Paul Eggert <eggert@twinsun.com>

8666 Reported by Alexandre Duret-Lutz.
8668 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

8732 Instead of blindly running autopoint, scan configure.ac (not the
8733 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8734 Reported by Paul D. Smith.
8736 2002-10-08 Paul Eggert <eggert@twinsun.com>
8738 Work around problems found when POSIXLY_CORRECT=1 is set.
8739 None of this seems to have anything to do with POSIX, really,
8740 but it's how Perl getopt works.
8741 * bin/autom4te.in (parse_args): Configure GetOpt with
8742 "permute", too.
8743 * doc/autoconf.texi (Invoking autom4te):
8744 --warning -> --warnings.
8745 * lib/autom4te.in: --warning -> --warnings.
8747 2002-09-28 Akim Demaille <akim@epita.fr>
8749 * doc/autoconf.texi (autom4te.cache): New section.
8751 2002-09-28 Akim Demaille <akim@epita.fr>
8753 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
8754 (Automake-preselections): Update.
8755 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
8757 2002-09-28 Akim Demaille <akim@epita.fr>
8759 * lib/autoscan/autoscan.pre: Move all the remaining rules to...

8761 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8762 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
8764 2002-09-28 Akim Demaille <akim@epita.fr>
8766 * tests/torture.at (Configuring subdirectories): Be robust to
8767 users who use config.site to require for a cache: in this case,
8768 the two last configure runs, using two different sets of
8769 arguments, trigger a legitimate error.
8771 2002-09-28 Akim Demaille <akim@epita.fr>
8773 * tests/m4sh.at (Functions Support, Functions and return Support):
8774 New.
8776 2002-09-28 Akim Demaille <akim@epita.fr>
8778 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
8779 autoheader are Perl programs.
8780 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
8781 (autom4te): Specify that the sources are in the $srcdir.
8782 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8784 2002-09-28 Akim Demaille <akim@epita.fr>

8787 (tm_zone): Move their rules to...
8788 * lib/autoconf/types.m4: here, using AN_ macros.
8789 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8790 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8791 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8792 * lib/autoconf/programs.m4: here.
8793 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
8794 (ETAGS_FOR_AUTOCONF): New.
8795 Use it.
8797 2002-09-28 Akim Demaille <akim@epita.fr>
8799 * lib/autoconf/autoscan.m4: New file.
8800 * lib/autoconf/autoconf.m4: Include it.
8801 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
8802 that were listed in the original autoscan.list.
8803 * lib/autoconf/headers.m4: Similarly with headers.
8804 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8805 (.m4.m4f): Don't pass --prepend-include, since that's done by
8806 tests/autom4te itself.
8807 * lib/autoscan/Makefile.am: Include freeze.mk.
8808 (autoscan.list): New target --this file is no longer a source.
8809 (autoscan.pre): New file.
8811 2002-09-28 Akim Demaille <akim@epita.fr>
8813 * bin/autoscan.in (@kinds): Make them singular.
8814 Adjust all uses.
8815 (&init_tables): When --debug, report the list of rules to ease
8816 tracking changes in autoscan.list.
8817 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8819 2002-09-28 Akim Demaille <akim@epita.fr>
8821 * lib/autoscan/functions, lib/autoscan/headers,
8822 * lib/autoscan/identifiers, lib/autoscan/makevars,
8823 * lib/autoscan/programs: Merge into...
8824 * lib/autoscan/autoscan.list: this.
8825 * bin/autoscan.in (&init_tables): Adjust.
8827 2002-09-28 Akim Demaille <akim@epita.fr>
8829 * lib/autoscan/functions, lib/autoscan/headers,
8830 * lib/autoscan/identifiers, lib/autoscan/makevars,
8831 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8832 `functions' line is now prefixed with `function:'.
8833 * bin/autoscan.in (&init_tables): Adjust.
8835 2002-09-28 Akim Demaille <akim@epita.fr>
8837 From now on, autoscan files must always map a macro name to a
8838 word: there is no `default' macro for autoscan.
8840 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8841 all.
8842 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8843 explicit.
8845 2002-09-28 Akim Demaille <akim@epita.fr>
8847 * bin/autoscan.in (%c_keywords): Remove.
8848 (&used): Keep only track of the words we might be interested in.
8849 (&output_kind): It is no longer needed to look for non active
8850 checks.
8852 2002-09-27 Akim Demaille <akim@epita.fr>
8854 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
8855 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
8856 * lib/autoscan/functions: Adjust.
8857 * doc/autoconf.texi (Particular Functions): Adjust.
8859 2002-09-27 Akim Demaille <akim@epita.fr>
8861 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8862 from /tmp.
8863 Thanks to Bill Moseley and Paul Eggert.
8864 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8865 the tmpdir must be created.
8866 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8867 dir be in the build tree, instead of $TMPDIR.
8869 2002-09-27 Akim Demaille <akim@epita.fr>
8871 * bin/autoscan.in: Improve the comments.
8872 (&parse_args): Drop obsolete undocumented options.
8873 (&output_kind): Output warnings.
8874 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
8875 (getwd): Trigger a warning.
8877 2002-09-26 Akim Demaille <akim@epita.fr>
8879 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8880 Reported by Ralf Corsepius.
8881 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8883 2002-09-26 Akim Demaille <akim@epita.fr>
8885 Single suffix rules and seperated dependencies are not portable.
8887 * doc/autoconf.texi (Installation Directory Variables): Update.
8888 (Limitations of Make): Some about `Single Suffix Rules and
8889 Separated Dependencies'.
8890 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8891 (ifnames, autoscan, autom4te): Un-factor into several rules.
8893 2002-09-25 Paul Eggert <eggert@twinsun.com>
8895 * BUGS (Interoperability bugs): New section. Mention libtool
8896 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8898 2002-09-24 Paul Eggert <eggert@twinsun.com>
8900 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8901 make handles suffix-rules differently from GNU make.
8903 * bin/Makefile.am (SUFFIXES, .in): Remove.
8904 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8905 Move the body of the old .in rule here.
8907 2002-09-16 Akim Demaille <akim@epita.fr>
8909 i960 compilers create `b.out' files by default.
8910 Reported by Ralf Corsepius.
8912 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8913 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8915 2002-09-13 Paul Eggert <eggert@twinsun.com>
8917 * doc/autoconf.texi (Particular Headers): Remove obsolete
8918 reference to `struct timezone' in the description of
8919 AC_HEADER_TIME.
8921 2002-09-13 Akim Demaille <akim@epita.fr>
8923 Version 2.54.
8925 * config/config.sub, config/config.guess: Update.
8926 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8927 * Makefile.am: Adjust.
8929 2002-09-13 Akim Demaille <akim@epita.fr>
8931 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8932 reading config.log when the compiler is rejected.
8933 Suggested by Guido Draheim.
8935 2002-09-13 Akim Demaille <akim@epita.fr>
8937 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8938 (chdir_init) might hang when stat'ing mounted directories.
8939 Reported by Vance Shipley.
8941 2002-09-12 Akim Demaille <akim@epita.fr>
8943 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8944 the lists.
8946 2002-09-12 Akim Demaille <akim@epita.fr>
8948 * doc/autoconf.texi (Defining Symbols): Present two different
8949 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8950 difference between 1 argument calls, and 2-3 argument calls.
8952 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8954 * doc/autoconf.texi: Review grammar and punctuation.
8956 2002-09-11 Paul Eggert <eggert@twinsun.com>
8958 * doc/autoconf.texi: Fix minor formatting, spelling, and
8959 grammatical typos.
8960 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8961 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8962 is obsolescent.
8964 2002-09-11 Akim Demaille <akim@epita.fr>
8966 * doc/autoconf.texi (Questions): Rename as...
8967 (FAQ): this.
8968 (Defining Directories): New.
8970 2002-09-09 Akim Demaille <akim@epita.fr>
8972 * doc/autoconf.texi (Making testsuite Scripts): Update.
8973 Suggested by Nishio Futoshi.
8975 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8977 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8978 plain `@' is wanted.
8980 2002-09-09 Akim Demaille <akim@epita.fr>
8982 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8983 `duplicates', since the algorithm was too naive and could keep
8984 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8985 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8986 Reported by Ralf Corsepius.
8987 * tests/torture.at (Configuring subdirectories): Exercise these
8988 cases.
8990 2002-09-09 Akim Demaille <akim@epita.fr>
8992 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8993 looking for a replacement file.
8994 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8995 directory is relative.
8996 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8997 directory definition.
8998 Reported by Andreas Schwab and Jim Meyering.
9000 2002-09-06 Akim Demaille <akim@epita.fr>
9002 * doc/autoconf.texi (Setting Output Variables): Clarify what
9003 precious variables are.
9004 Suggested by Pontus Skoeld.
9006 2002-09-05 Akim Demaille <akim@epita.fr>
9008 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9009 (ifnames, autoscan, autom4te): Since we don't only depend on
9010 configure.ac variables (such as VERSION etc.), but also on prefix
9011 and so forth, depend on Makefile, not configure.ac.
9012 Reported by Alexandre Duret-Lutz.
9013 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9015 2002-09-05 Kevin Ryde <user42@zip.com.au>
9017 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9018 doesn't seem to be confined to ia64, just say "some versions".
9020 2002-09-04 Akim Demaille <akim@epita.fr>
9022 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9023 Automake 1.6c.
9024 * Makefile.am (maintainer-clean-local): Remove.
9025 (MAINTAINERCLEANFILES): Remove COPYING.
9027 2002-09-03 Paul Eggert <eggert@twinsun.com>
9029 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9030 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9031 Brinkmann.
9033 2002-09-03 Akim Demaille <akim@epita.fr>
9035 * configure.ac: Bump to 2.53d.
9036 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9037 as of today, on Automake's team suggestion.
9039 2002-09-03 Akim Demaille <akim@epita.fr>
9041 Version 2.53c.
9043 2002-09-02 Akim Demaille <akim@epita.fr>
9045 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9046 SITE_MACRO_DIR.
9047 * configure.ac: Disable SITE_MACRO_DIR.
9049 2002-09-02 Jim Meyering <meyering@lucent.com>
9051 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9052 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9053 Also, tweak grammar: s/make sure to/be sure to/.
9055 2002-09-02 Paul Eggert <eggert@twinsun.com>
9057 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9058 directory names are generally preferable to physical names.
9060 2002-09-02 Akim Demaille <akim@epita.fr>
9062 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9063 Reported by Raja R. Harinath.
9064 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9065 * bin/autoupdate.in: Use error instead of die.
9067 2002-09-01 Paul Eggert <eggert@twinsun.com>
9069 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9070 ordinary shell concatenation rather than echo+tr+sed command that
9071 runs afoul of a long-line-related sed bug in Solaris 8.
9073 * bin/autoheader.in (parse_args): --warning -> --warnings.
9075 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9076 stdout, as traditional "ls" does.
9077 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9078 _AC_COMPILER_EXEEXT_O): Likewise.
9079 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9081 * bin/autoconf.as: Add --prepend-include option. This patch was
9082 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9083 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9085 * bin/autoconf.in, configure: Regenerate.
9087 * doc/autoconf.texi (Special Shell Variables): Mention
9088 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9090 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9091 MAILPATH and set PS1, PS2, PS4 to default values, to work
9092 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9093 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9094 the Autoconf documentation specifies; fall back to "unset" only if
9095 this fails. Use a shell for-loop for this rather than an m4 loop,
9096 to shorten the output script.
9098 2002-08-30 Paul Eggert <eggert@twinsun.com>
9100 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9101 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9102 for the CDPATH problem. Document PWD.
9103 (Limitations of Builtins): Document the problem that "cd $foo" and
9104 "ls $foo" may refer to different directories in shells conforming
9105 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9106 example, since the old example is now out of date.
9108 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9109 FOO" and "ls FOO" talk about different directories; this catches
9110 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9111 spaghetti.
9113 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9114 of rolling our own unset.
9115 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9116 in practice we needn't worry about CDPATH if unset doesn't work.
9118 * Makefile.in, aclocal.m4, bin/Makefile.in,
9119 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9120 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9121 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9122 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9123 tests/Makefile.in: Regenerate with Automake 1.6.3.
9125 * config/config.guess, config/config.sub, config/mkinstalldirs:
9126 Update.
9128 * configure: Regenerate with self.
9130 2002-08-30 Kevin Ryde <user42@zip.com.au>
9132 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9133 default output.
9135 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9137 * bin/autom4te.in (Request::load): Correctly test for "do" read
9138 failure.
9140 2002-08-29 Akim Demaille <akim@epita.fr>
9142 * lib/Autom4te/General.pm (&xqx): New.
9143 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9144 hand, which is not portable.
9145 (&error): New.
9146 * bin/autom4te.in: Use them.
9147 Use &error instead of die.
9148 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9149 Adjust.
9151 2002-08-17 Paul Eggert <eggert@twinsun.com>
9153 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9154 default list of compilers to try, since it was long ago superseded
9155 by the ksh fc builtin. Suggested by Steven G. Johnson.
9157 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9159 * doc/autoconf.texi (Invoking autom4te): End the option table,
9160 fixing a bug introduced by the previous patch.
9161 (Limitations of Make): Add a 'target lookup' subentry in the
9162 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9164 2002-07-29 Mark D. Roth <roth@feep.net>
9166 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9167 options and use $AUTOM4TE_PATH.
9168 * doc/autoconf.texi: Remove documentation of autom4te
9169 --include-envvar and --site-macro-subdir options and document
9170 use of $AUTOM4TE_PATH.
9171 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9172 arguments from each language section.
9174 2002-07-29 Paul Eggert <eggert@twinsun.com>
9176 * doc/install.texi: Include copyright symbol in copyright notice.
9178 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9179 Replace with:
9180 (AM_MAKEINFOFLAGS): New macro.
9181 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9182 * Makefile.am (INSTALL): Use the new macros.
9183 Use -o rather than --output, since "missing" does not grok --output.
9185 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9187 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9188 comments do not always work. Never trust the exit status of
9189 `make -k'.
9191 2002-07-24 Kevin Ryde <user42@zip.com.au>
9193 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9194 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9196 2002-07-23 Paul Eggert <eggert@twinsun.com>
9198 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9199 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9200 apparently treats PATH="nonexistent" as if it contained ".".
9201 Bug reported by Stefan `Sec' Zehl.
9203 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9205 * doc/autoconf.texi (Limitations of Make): Mention the special
9206 handling of the obj/ directory by BSD make.
9208 2002-07-20 Kevin Ryde <user42@zip.com.au>
9210 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
9211 backslashes.
9213 2002-07-19 Akim Demaille <akim@epita.fr>
9215 * doc/autoconf.texi (Function Portability): `exit'.
9216 (Programming in M4sh): Ethymology of M4sh.
9218 2002-07-19 Akim Demaille <akim@epita.fr>
9220 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.

9325 so that Emacs setups GNU style for perl-mode and cperl-mode.
9327 2002-06-27 Paul Eggert <eggert@twinsun.com>
9329 * config/install-sh: Quote $src. Prefer || to test's -o option,
9330 as per "Limitations of Builtins".
9331 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
9332 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9334 * tests/mktests.sh: Use grep instead of fgrep, as per
9335 "Limitations of Builtins".

9354 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
9355 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
9356 on Solaris 2.5.1.
9358 2002-06-11 Andreas Schwab <schwab@suse.de>

9362 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9364 * bin/autom4te.in ($cache): Don't define using `$me', the name

9368 2002-06-07 Akim Demaille <akim@epita.fr>
9370 * tests/tools.at (autoconf: forbidden tokens, basic)

9379 2002-06-07 Akim Demaille <akim@epita.fr>
9381 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
9382 rename as...
9383 (AC_REPLACE_FNMATCH): this.
9384 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
9385 AC_FUNC_FNMATCH_GNU.
9387 2002-06-07 Akim Demaille <akim@epita.fr>
9389 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
9390 Rosetta Stone for Unix.
9392 2002-06-07 Akim Demaille <akim@epita.fr>
9394 * bin/autom4te.in (warn_forbidden): When rejecting a token,
9395 suggest m4_pattern_allow.
9396 Suggested by Adam J. Richter.
9398 2002-06-07 Akim Demaille <akim@epita.fr>
9400 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

9403 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
9404 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.

9406 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
9407 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
9408 (AC_REPLACE_FNMATCH_GNU): these.
9409 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
9410 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
9411 * tests/mktests.sh (ac_exclude_list): Don't check

9416 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
9417 if ln doesn't work.
9418 * NEWS: Likewise.
9419 * doc/autoconf.texi (Configuration Links): Likewise.

9422 2002-06-05 Paul Eggert <eggert@twinsun.com>
9424 * config/config.guess, config/config.sub, config/texinfo.tex:
9425 Update from masters.
9427 2002-05-29 Paul Eggert <eggert@twinsun.com>

9454 2002-05-23 Akim Demaille <akim@epita.fr>
9456 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
9457 version of Autoconf that is discussed.
9459 2002-05-22 Paul Eggert <eggert@twinsun.com>
9461 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
9462 from the default list of compilers to try. Suggested by
9463 Kate Hedstrom.
9464 * NEWS: Document the above.
9465 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
9467 2002-05-17 Paul Eggert <eggert@twinsun.com>
9469 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9470 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9471 This improves on an earlier suggestion by H. Peter Anvin.
9473 2002-05-16 Paul Eggert <eggert@twinsun.com>
9475 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9476 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9477 Both macros now accept an optional source-dir arg.
9478 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9480 * NEWS: Document this.
9481 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9483 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9484 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9485 not for GNU extensions; this undoes part of the 2000-11-03 change,
9486 reverting to 2.13-compatible behavior.
9487 Add new optional argument DIR.
9488 (AC_FUNC_FNMATCH_GNU): New macro.
9490 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9492 2002-05-08 Paul Eggert <eggert@twinsun.com>
9494 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9495 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9496 and it causes a 'test' syntax error if it fails.
9497 Bug reported by Stephen Gildea.
9499 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9500 If prototypes are supported, use them to check this at compile-time,
9501 instead of trying to check it at run-time. If we must do a run-time
9502 check, assume that setvbuf is standard when cross-compiling, as
9503 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9504 Bug reported by Paul D. Smith.
9506 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9507 argument specifying location of getloadavg.c. This removes a
9508 FIXME. This idea was taken from Jim Meyering's implementation in
9509 textutils.
9510 * doc/autoconf.texi (Particular Functions): Document this.
9511 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9512 that's what the code does; this fixes a bug reported by
9513 Paul D. Smith.
9515 2002-05-03 Akim Demaille <akim@epita.fr>
9517 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9518 autopoint instead of gettextize.
9519 ($uses_alocal): Rename as...
9520 ($uses_aclocal): this.
9521 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9522 Suggested by Bruno Haible.
9524 2002-05-03 Akim Demaille <akim@epita.fr>
9526 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9528 2002-04-29 Paul Eggert <eggert@twinsun.com>
9530 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9531 files to be 1 second older; just set them to be the same time.
9532 Also, sleep 1 second after the first aclocal, to work around
9533 problems with sub-second time stamps on the input files.
9535 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9537 * doc/autoconf.texi: Mention "set -e -x" lossage
9538 under node "Limitations of Builtins".
9540 2002-04-29 Akim Demaille <akim@epita.fr>
9542 * doc/install.texi: Better wording for setting variables when
9543 running configure.
9544 From Christian Cornelssen.
9546 2002-04-29 Akim Demaille <akim@epita.fr>
9548 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9549 of lack of $LINENO support, then the test will compare the $LINENO
9550 in testsuite vs. the lineno in the test file. This is wrong, of
9551 course.
9552 Be sure to protect it.
9553 Reported by Patrick Welche.
9555 2002-04-25 Akim Demaille <akim@epita.fr>
9557 * doc/autoconf.texi (Obsolete Macros): Typo.
9558 Reported by Vladimir Volovich.
9560 2002-04-25 Akim Demaille <akim@epita.fr>
9562 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9563 than some of the input files, hence, on the second run of aclocal,
9564 if some of its input are younger, make them older.
9565 Suggested by Paul Eggert.
9567 2002-04-25 Akim Demaille <akim@epita.fr>
9569 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9570 Thanks to Paul Eggert.
9572 2002-04-25 Akim Demaille <akim@epita.fr>
9574 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9575 and ac_subst_vars be sh variables containing the list of
9576 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9577 DEFAULT diversion.
9578 (_AC_INIT_PREPARE): Use them to log them.
9579 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9580 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9581 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9582 _AC_SUBST_FILES and _AC_SUBST_VARS.
9583 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9585 2002-04-24 Akim Demaille <akim@epita.fr>
9587 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9588 autoheader, so that automake does not complain about a missing
9589 config.h.in that was to be created.
9591 2002-04-23 Akim Demaille <akim@epita.fr>
9593 * bin/autoheader.in (parse_args): --warning takes an argument.
9594 Fixes PR/220.
9596 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9598 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

9609 2002-04-22 Akim Demaille <akim@epita.fr>
9611 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
9612 comma.
9613 Reported by Gregory Giannoni.
9615 2002-04-22 Akim Demaille <akim@epita.fr>
9617 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
9618 Fixes false failures on Darwin.
9620 2002-04-21 Paul Eggert <eggert@twinsun.com>

9624 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

9643 Minor spelling and grammar fixes.
9645 * doc/autoconf.texi: Follow the outline suggested in the GNU
9646 Sample Texts sections of the Texinfo 4.2 manual. Most
9647 importantly, this makes sure that the copyright notices appear in
9648 all output formats. You probably need Texinfo 4.2 to generate
9649 the manual now.
9651 Fix some bugs when using "$@" when there might be zero positional
9652 arguments in cases where this matters.

9672 * tests/c.at: We can't have zero arguments, so remove workaround
9673 that is not portable to Zsh.
9675 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9677 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

9689 From Oliver Kiddle and Peter Stephenson.
9691 Have M4sh perform minimal shell sanitizing.
9693 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'

9696 (AS_PREPARE): New.
9697 (AS_INIT): Invoke AS_SHELL_SANITIZE.

9700 Adjust Autoconf and Autotest.

9703 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9704 * lib/autotest/general.m4 (AT_INIT): Likewise.
9705 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9706 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9707 AS_SHELL_SANITIZE.
9709 Use this M4sh to generate Autoconf's shell scripts.
9711 * tests/wrapsh.as: New, precursor of wrapsh.in.
9712 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9713 on Autotest and M4sh.
9714 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9715 (wrapsh.in): New target.
9716 * bin/autoconf.as: New, precursor of autoconf.in.
9717 (autoconf.in): New target.
9719 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

9722 with indented comments in rules.

9726 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9727 ac_top_builddir when setting ac_abs_top_builddir.

9731 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9732 (Portable Shell): Cross reference to Systemology.
9734 2002-04-05 Akim Demaille <akim@epita.fr>
9736 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9737 directories when descending in a SUBDIRS.
9738 Reported by Ezra Peisach.
9740 2002-04-04 Andreas Schwab <schwab@suse.de>
9742 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9743 contains no literal separators.
9745 2002-04-03 Akim Demaille <akim@epita.fr>
9747 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9748 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9749 Use dnl, not the KILL diversion.
9750 Extracted from...
9751 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9752 (AC_CONFIG_LINKS): here.
9753 Adjust.
9754 Don't use the KILL diversion, as it kills spurious output, which
9755 results in failures being hidden.
9756 Use m4_defn where appropriate.
9757 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9758 after the second argument.
9759 Use m4_defn.
9760 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9761 syntax, as it is provided by M4sugar.
9762 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9764 2002-04-03 Andreas Schwab <schwab@suse.de>
9766 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9767 expanded if $# <= 2.
9769 * bin/autoreconf.in (autoreconf): Run automake after rerunning
9770 aclocal.
9772 2002-04-03 Akim Demaille <akim@epita.fr>
9774 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
9775 (_AC_COMPILER_EXEEXT_REJECT): New.
9776 Also recognize *.bb and *.bbg as compilation byproducts.
9777 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9778 (_AC_COMPILER_OBJEXT): Use them.
9779 Fixes Debian #138666.
9781 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9783 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9785 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9786 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9787 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9788 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9789 (AC_C_CONST): Same.
9790 (AC_C_INLINE): Same.
9791 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
9792 * doc/autoconf.texi, NEWS: Document.
9793 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9794 AC_C_CROSS.
9796 2002-04-02 Akim Demaille <akim@epita.fr>

9799 _AS_MKDIR_P_PREPARE.
9801 2002-03-28 Kevin Ryde <user42@zip.com.au>
9803 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9804 to avoid versions of HP C which don't allow that.
9806 2002-03-27 Paul Eggert <eggert@twinsun.com>
9808 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9809 (AS_SHELL_SANITIZE): Invoke it.
9810 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9812 2002-03-26 Akim Demaille <akim@epita.fr>
9814 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9816 2002-03-26 Akim Demaille <akim@epita.fr>
9818 * doc/autoconf.texi (Introduction): The GNATS base moved.
9820 2002-03-25 Paul Eggert <eggert@twinsun.com>
9822 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9823 as POSIX requires, as it doesn't work with Zsh.
9824 * doc/autoconf.texi (Assignments): Document the problem.
9826 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9828 * doc/autoconf.texi (Limitations of Make): Mention more issue
9829 about VPATH, overriding of macros in sub-makes, and handling of
9830 SHELL.
9832 2002-03-21 Paul Eggert <eggert@twinsun.com>
9834 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9835 problem with here-document buffer boundaries.
9837 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9838 when reinvoking the shell, to work around problems with installers
9839 who put strange things like "cd" commands in their environments.
9841 2002-03-19 Akim Demaille <akim@epita.fr>
9843 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9844 From Aaron Ucko.
9846 2002-03-19 Akim Demaille <akim@epita.fr>
9848 * bin/autoscan.in (scan_file): Specify the location in `&used'
9849 invocations.
9850 From Nicolas Joly.
9852 2002-03-19 Akim Demaille <akim@epita.fr>
9854 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9855 From Nishio Futoshi.
9857 2002-03-19 Akim Demaille <akim@epita.fr>
9859 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9861 2002-03-18 Paul Eggert <eggert@twinsun.com>
9863 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9864 (Limitations of Usual Tools): Add mkdir section.
9866 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9867 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9868 back on AS_DIRNAME to compute prefixes otherwise; this is
9869 roughly what mkinstalldirs does. That way, we need not have
9870 our own filename disassembler. The old disassembler did not
9871 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9873 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9874 Create at_test_all by a series of assignments,
9875 not by a single assignment of a long string. The latter causes ksh
9876 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9877 presumably because of a buffer overrun.
9879 2002-03-14 Paul Eggert <eggert@twinsun.com>
9881 * lib/autotest/general.m4 (at_times_skip):
9882 Renamed from at_times. Now a boolean.
9883 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9884 says 'times: not found'.
9886 2002-03-14 Akim Demaille <akim@epita.fr>
9888 * bin/autoreconf.in (&study_gettextize): New.
9889 (&autoreconf): Handle newest gettextize.
9890 Rerun aclocal if needed.
9891 Suggested by Andreas Schwab.
9893 2002-03-13 Akim Demaille <akim@epita.fr>
9895 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9897 2002-03-13 Akim Demaille <akim@epita.fr>
9899 * doc/autoconf.texi (Header Portability): New.
9900 Add information about stdint.h and inttypes.h from Paul Eggert.
9902 2002-03-13 Akim Demaille <akim@epita.fr>
9904 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9905 -p'.
9906 From Bob Proulx.
9908 2002-03-12 Akim Demaille <akim@epita.fr>
9910 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9911 m4_require.
9913 2002-03-11 Andreas Schwab <schwab@suse.de>
9915 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9916 does not do it if --with-lispdir is given.
9918 2002-03-08 Akim Demaille <akim@epita.fr>
9920 Version 2.53.
9922 2002-03-08 Akim Demaille <akim@epita.fr>
9924 * doc/autoconf.texi (Subdirectories): Clarify that the
9925 subdirectory should exist.
9927 2002-03-08 Akim Demaille <akim@epita.fr>
9929 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9931 2002-03-08 Akim Demaille <akim@epita.fr>
9933 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9934 aliases the actual variables, and modifications of the former
9935 affect the latter.
9937 2002-03-08 Akim Demaille <akim@epita.fr>
9939 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9940 because of C-c: have m4 output in tmp files, then mv them.
9942 2002-03-08 Akim Demaille <akim@epita.fr>
9944 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9945 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9946 * bin/ifnames.in: Copyright update.

9950 * doc/autoconf.texi (Invoking autom4te): New.
9952 2002-03-05 Akim Demaille <akim@epita.fr>
9954 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9955 Kevin Ryde.
9957 2002-03-05 Akim Demaille <akim@epita.fr>
9959 Version 2.52i.
9961 2002-03-04 Akim Demaille <akim@epita.fr>
9963 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9964 * lib/autoconf/general.m4 (AC_INIT): More informative error
9965 message for LIBOBJ.
9967 2002-03-04 Akim Demaille <akim@epita.fr>
9969 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9970 parallel builds.
9972 2002-03-04 Akim Demaille <akim@epita.fr>
9974 * doc/autoconf.texi (Transforming Names): Equality between target
9975 and host is irrelevant.
9976 (Specifying Names, Canonicalizing): Remove all references to the
9977 backward compatibility hooks. Rather, collect them all into...
9978 (Hosts and Cross-Compilation): this new section.
9979 * doc/install.texi (System Type): Ditto.
9980 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9981 that `--host' implies cross-compilation.
9983 2002-03-04 Akim Demaille <akim@epita.fr>
9985 * doc/autoconf.texi (Evaluation Macros): New.
9986 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9987 useless.
9988 (_m4_foreach): Define the variant with immediate evaluation so
9989 that it contains exactly the items, not an expression which
9990 evaluation is the current item.
9991 (m4_re_string, m4_re_word): Don't over quote them.
9993 2002-03-04 Akim Demaille <akim@epita.fr>
9995 Instead of having stacking `shift's evaluated at the end, let
9996 `foreach' loops immediately evaluate them.
9998 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9999 $*. This is the n-th time I change my mind, but hopefully this is
10000 the last...
10001 (m4_lquote): New.
10002 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10003 efficient.
10004 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10005 it was only a hack for m4_text_wrap.
10006 (m4_car2): Remove, replaced by...
10007 (m4_cdr): New.
10008 (_m4_foreach): Adjust.
10009 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10010 m4_bpatsubst for clarification.
10012 2002-03-04 Akim Demaille <akim@epita.fr>
10014 * doc/autoconf.texi (Changequote is Evil): New.
10016 2002-03-03 Kevin Ryde <user42@zip.com.au>
10018 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
10019 on old systems like SunOS.

10041 From Akinori Musha.
10043 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
10045 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
10046 translate \r\n to \n.
10048 2002-02-07 Akim Demaille <akim@epita.fr>
10050 Version 2.52h.
10052 2002-02-07 Akim Demaille <akim@epita.fr>
10054 Fix Autoconf PR/209.
10055 Also reported by Frank Denis.
10057 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
10059 2002-02-07 Akim Demaille <akim@epita.fr>
10061 Fix Autoconf PR/207:
10062 AC_PREFIX_PROGRAM fails with dashed program names
10064 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
10065 variable when looking for the prefix program.
10066 Now it also works for shell variables.
10068 2002-02-07 Akim Demaille <akim@epita.fr>
10070 * doc/autoconf.texi (Limitations of Builtins): More about
10071 case/esac.
10073 2002-02-06 Akim Demaille <akim@epita.fr>
10075 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
10076 case/esac, some shells don't support it.
10077 Reported by Zack Weinberg.
10078 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
10080 2002-02-06 Akim Demaille <akim@epita.fr>
10082 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
10083 sure not to introduce newlines in at_groups.
10084 * lib/autotest/Makefile.am (autotest.m4f): Typo.
10086 2002-02-06 Akim Demaille <akim@epita.fr>
10088 * tests/torture.at (Configuring subdirectories): Skip if aclocal
10089 is not available.
10091 2002-02-05 Paul Eggert <eggert@twinsun.com>
10093 * doc/autoconf.texi (Specific Compiler Characteristics):
10094 Describe HP-UX cc bug workaround more accurately.
10095 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
10096 not unsigned long.
10097 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
10098 cross-compilers, too. This undoes some of the most recent change
10099 to this file.
10101 2002-02-05 Akim Demaille <akim@epita.fr>
10103 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
10104 to make sure they are up to date when `check' is run.
10106 2002-02-05 Akim Demaille <akim@epita.fr>
10108 * doc/autoconf.texi (Making testsuite Scripts): Document

10113 * lib/freeze.mk: New.
10115 2002-02-05 Akim Demaille <akim@epita.fr>
10117 Implement `autom4te --freeze'.
10119 * bin/autom4te.in (&freeze): New.
10120 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
10121 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
10123 2002-02-05 Akim Demaille <akim@epita.fr>
10125 * bin/autom4te.in (&parse_args): Implement `frozen files are
10126 optional are the sum of the previous files on the command line'.
10127 Also, pass `--reload-state=' on them, so...
10128 (handle_m4): don't.
10129 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10130 (M4sh): Rely on M4sugar.
10131 (Autotest, M4sh, M4sugar): Use frozen files.
10133 2002-01-31 Akim Demaille <akim@epita.fr>
10135 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
10136 * doc/autoconf.texi (Initializing configure): Adjust.
10138 2002-01-30 Akim Demaille <akim@epita.fr>
10140 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
10141 alphanumeric to `-' instead of `_'.
10143 2002-01-30 Akim Demaille <akim@epita.fr>
10145 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10146 for plain code, the other for cross-compilation code. The latter
10147 is now run with GCC only.
10148 * doc/autoconf.texi (Compilers and Preprocessors): New.
10150 2002-01-30 Akim Demaille <akim@epita.fr>
10152 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
10153 values.
10154 * doc/autoconf.texi (Initializing configure): Explain how to
10155 change AC_INIT default values.
10157 2002-01-29 Akim Demaille <akim@epita.fr>
10159 * tests/torture.at (Configuring subdirectories): Use configure.in,
10160 so that aclocal 1.4 works.
10161 Reported by Alexandre Duret-Lutz and Larry Schmitt.
10163 2002-01-28 Akim Demaille <akim@epita.fr>
10165 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10166 needs an argument.
10168 2002-01-28 Akim Demaille <akim@epita.fr>
10170 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10171 AUTOTEST_PATH *after* it was set.
10172 Don't put `.' in the PATH: the user should be precise and `./' if
10173 needed. In addition, given that the test suite does some `cd', if
10174 `.' is in the path, the `tested programs' sections will report
10175 programs found in the test suite's directory, while during the
10176 tests (performed in their own directory), these programs are no
10177 longer visible. In other words, the results is confusing and
10178 useless.
10179 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10181 2002-01-24 Akim Demaille <akim@epita.fr>

10253 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10254 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10255 and PACKAGE_BUGREPORT from here...
10256 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10257 arguments.
10258 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10259 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

10283 2001-12-14 Akim Demaille <akim@epita.fr>
10285 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10286 trailing files, don't apply `-rf' to files which might not be
10287 created by configure (core, core.*, and *.core), but just `rm -f'.
10288 Suggested by Jonathan Kamens.
10290 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10292 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

10296 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
10298 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

10306 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10308 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
10310 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
10311 C/Fortran linking on HP/UX, by extracting the Fortran library
10312 search path from the LPATH line in the $F77 -v output.
10314 2001-12-12 Kevin Ryde <user42@zip.com.au>
10316 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10317 forbidden file descriptors table.
10319 2001-11-26 Akim Demaille <akim@epita.fr>
10321 * bin/autoscan.in (%c_keywords): Build it at top level.
10322 Map to 1 in order to simplify its uses.
10324 2001-11-26 Akim Demaille <akim@epita.fr>
10326 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10327 Remove $filepath, useless.
10328 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10329 variables, they are really part of the tokens.
10330 Split the input line on spaces and then look for tokens.
10331 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10332 because of `lex$U.$(OBJEXT)'.
10333 (&scan_files): Use "@list" instead of join.
10334 * doc/Makefile.am (CLEANFILES): Add *.fns.
10336 2001-11-26 Akim Demaille <akim@epita.fr>
10338 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10339 Remove, replaced by...

10355 (&check_configure_ac): Use long options.
10356 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10358 2001-11-26 Akim Demaille <akim@epita.fr>
10360 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10361 Before, having a line containing the opening of a multi line
10362 comment made the whole line be ignored.
10364 2001-11-26 Akim Demaille <akim@epita.fr>
10366 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10367 (testsuite Scripts): Be one of its subsection.
10368 (Autotest Logs): New.
10370 2001-11-26 Akim Demaille <akim@epita.fr>
10372 Test groups are now run two directories deeper.
10374 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10375 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10376 at_top_builddir.
10377 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10378 top_srcdir, builddir and top_builddir.
10379 Use `at_*dir' relatively to the directory containing the
10380 suite, use `*dir' when relatively to the current group dir.
10382 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10384 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10385 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10386 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10387 spelling errors.
10389 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10391 * doc/autoconf.texi (Using System Type): Add an example of `case
10392 $host' usage so people quit using `case $target' everywhere.
10394 2001-11-22 Akim Demaille <akim@epita.fr>
10396 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10397 spotted by Jim Meyering.
10399 2001-11-16 Paul Eggert <eggert@twinsun.com>
10401 This patch implements a `long double' suggestion by Oliver Kiddle.
10403 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10404 static, to catch errors if the value isn't known at compile-time
10405 and the compiler supports dynamic arrays. Change its name from
10406 `_array_' to `test_array' to avoid potential name clashes.
10407 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10408 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10409 better than double. Catch a bug in GCC 2.95.2 x86.
10410 * doc/autoconf.texi (C Compiler): Document the above.
10411 * NEWS: Likewise.
10413 2001-11-13 Akim Demaille <akim@epita.fr>
10415 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10416 hand.
10417 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10419 2001-11-13 Akim Demaille <akim@epita.fr>
10421 * lib/autotest/general.m4 (AT_INIT): After having run the test
10422 group, go back to the initial directory, not to at_suite_dir.
10424 2001-11-13 Akim Demaille <akim@epita.fr>
10426 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10427 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10428 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10429 option.
10430 (AT_CHECK_CONFIGURE): Use absolute paths.
10431 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10432 The problem is still the old one: there is no means in M4 (that I
10433 know about) to create a defining macro, because there is no means
10434 to create `$1' etc., therefore, the defining macro ``swallows''
10435 all the arguments meant to the defined macro.
10437 2001-11-13 Akim Demaille <akim@epita.fr>
10439 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10440 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10441 configure.ac.
10442 * tests/aclocal.m4: Remove, as it is no longer used.
10444 2001-11-13 Akim Demaille <akim@epita.fr>
10446 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10447 variable names when referring to a single test group, or to
10448 `suite' when referring to the whole test suite.
10449 `at_last_test' is removed: m4 compute at_format itself.
10450 (at_stdout, at_stder1, at_stderr): New variables.
10451 (AT_CHECK): Use them.
10453 2001-11-13 Akim Demaille <akim@epita.fr>
10455 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10456 in PATH.
10457 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10458 Do it as soon as a test fails, don't wait till the end of the test
10459 suite.
10460 Don't remove $as_me.[0-9]*, since these files no longer exist.
10462 2001-11-13 Akim Demaille <akim@epita.fr>
10464 * tests/tools.at: Use absolute paths, since we are no longer run
10465 in place.
10467 2001-11-13 Akim Demaille <akim@epita.fr>
10469 Now that tests are running in their own private dir, there is no
10470 need to list the files to remove at the end of tests groups.
10472 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10473 (AT_data_files, at_data_files): Remove.
10474 (AT_CLEANUP, AT_DATA): Simplify.
10475 (AT_INIT): Adjust.
10476 Remove the group dir if !debug && !failed.
10477 * tests/atspecific.m4: Adjust.
10479 2001-11-13 Akim Demaille <akim@epita.fr>
10481 Start a new layout for Autotest: `testsuite' creates
10482 `testsuite.dir' in which the at-check-line etc. files are to be
10483 found, and `testsuite.dir/003' where the test group 3 is run.
10485 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10486 at_check_line_file, at_format, at_test_normalized, at_group_dir
10487 are new variables.
10488 Create the directories.
10489 Use absolute paths for at- files.
10490 (AT_CHECK): Adjust.
10492 2001-11-11 Michael Matz <matz@kde.org>
10494 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10495 (m4_car2): New.
10496 (m4_car): Properly quote arguments.
10498 2001-11-13 Akim Demaille <akim@epita.fr>
10500 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10501 with stricter rules on LIBOBJS.
10503 2001-11-12 Paul Eggert <eggert@twinsun.com>
10505 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10506 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10507 __PROTOTYPES too.
10509 2001-11-12 Akim Demaille <akim@epita.fr>
10511 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10513 2001-11-12 Akim Demaille <akim@epita.fr>
10515 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10516 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10517 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10518 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10519 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10520 specify to what the macro should be defined (typically to 1).
10522 2001-11-12 Akim Demaille <akim@epita.fr>
10524 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10525 From Jim Meyering.
10527 2001-11-12 Akim Demaille <akim@epita.fr>
10529 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10530 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10531 definition used by Automake where LEX is +/- "${missing} lex" and
10532 `missing' itself contains variables.
10534 2001-11-12 Akim Demaille <akim@epita.fr>
10536 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10537 Now that M4sh pushes BODY, the comments were output at the end of
10538 the test suites.
10540 2001-11-08 Akim Demaille <akim@epita.fr>
10542 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10543 that we can trace macros from aclocal.m4.
10544 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10545 obsoleted, and redirect to the former anyway.
10546 Reported by Ralf Corsepius.
10548 2001-11-08 Akim Demaille <akim@epita.fr>
10550 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10551 processed only if present.
10552 * tests/torture.at (Configuring subdirectories): Use autoreconf
10553 instead of successive calls to autoconf.
10554 Add a nonexistent subdirectory to exercise the patch above.
10555 Reported by Ralf Corsepius.
10557 2001-11-08 Kevin Ryde <user42@zip.com.au>
10559 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10560 doesn't accept .S files.
10562 2001-11-07 Akim Demaille <akim@epita.fr>
10564 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10565 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10566 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10567 * bin/autom4te.in (warn_forbidden): New.
10568 (handle_output): Use it.
10569 Read m4_pattern_forbid with messages.
10571 2001-11-05 Akim Demaille <akim@epita.fr>
10573 * bin/autom4te.in (--normalize): Remove.
10574 * lib/autom4te.in: Adjust.
10576 2001-11-05 Akim Demaille <akim@epita.fr>
10578 * tests/Makefile.am (testsuite): Rename this target as...
10579 ($(TESTSUITE)): this.
10580 From Nicolas Joly.
10582 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10584 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10585 the --prefix option, also remove it's argument.
10587 2001-11-05 Akim Demaille <akim@epita.fr>
10589 * doc/autoconf.texi (testsuite Invocation): Update.
10590 (Writing testsuite.at): Update.
10592 2001-11-03 Akim Demaille <akim@epita.fr>
10594 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10596 2001-11-03 Akim Demaille <akim@epita.fr>
10598 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10599 (&file_name_is_absolute): New, wrappers around routines from
10600 File::Spec.
10601 Use and export them.
10602 (&find_configure_ac): Optionally take a directory where to look at.
10603 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10604 the arguments.
10605 Default @ARGV to `.', not find_configure_ac.
10606 (&autoreconf): Argument is a directory.
10607 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10608 * doc/autoconf.texi (autoreconf Invocation): Update.
10610 2001-11-03 Akim Demaille <akim@epita.fr>
10612 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10613 (@export_forward_subs): New.
10614 Add basename, dirname, and fileparse.
10615 (@EXPORT): Adjust.
10616 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10617 Don't look for aclocal flags if we already know aclocal is not
10618 used.
10619 Move aclocal.m4t only if it exists.
10620 Reported by Ezra Peisach.
10622 2001-11-03 Akim Demaille <akim@epita.fr>
10624 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10625 passed on command line, defaulting to ./configure.ac if present.
10626 (&maybe_autoreconf, File::Find): Remove, unused.
10627 (&autoreconf): If autoconf is not used, don't try to trace.
10629 2001-11-02 Akim Demaille <akim@epita.fr>
10631 * configure.ac: Bump to 2.52g.
10633 2001-11-02 Akim Demaille <akim@epita.fr>
10635 Version 2.52f.
10637 2001-11-02 Akim Demaille <akim@epita.fr>
10639 * config/config.guess, config/config.sub, doc/standards.texi:
10640 * config/lispdir.m4: Update from masters.

10643 2001-11-02 Akim Demaille <akim@epita.fr>
10645 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10646 Don't run aclocal when aclocal.m4 is not from aclocal.
10647 From Ezra Peisach.
10648 Don't run libtoolize and gettextize if --install is not given.
10650 2001-11-01 Paul Eggert <eggert@twinsun.com>
10652 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10653 be invoked before _AS_LINENO_PREPARE.
10654 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10655 than character ranges.
10657 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10658 invoking AS_BASENAME. Set the locale variables to 'C' if
10659 possible, as POSIX requires this to get the traditional
10660 behavior.
10661 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10663 2001-10-31 Paul Eggert <eggert@twinsun.com>
10665 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10666 with {}, as that triggers a bug in Bash 2.05.
10668 (_AS_LINENO_PREPARE): Use Sed rather than
10669 Awk. Fix the sed prepass to work even if there are multiple
10670 instances of $LINENO on the same line. Do not substitute for
10671 other variables like $LINENOT. Do not check file dates; such a
10672 check is unreliable on sufficiently fast machines, and removing
10673 the check makes the code simpler and more reliable. Check for
10674 output and chmod failures.
10676 * doc/autoconf.texi (Special Shell Variables): Document
10677 the above.
10679 2001-10-31 Akim Demaille <akim@epita.fr>
10681 * tests/Makefile.am (atconfig): Remove this target, Automake
10682 handles it now.
10684 2001-10-31 Akim Demaille <akim@epita.fr>
10686 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10687 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10688 provided, while it is optional.
10689 * configure.ac: Adjust.
10691 2001-10-26 Paul Eggert <eggert@twinsun.com>
10693 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10694 lib/Autom4te/Struct.pm:
10695 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10696 with 5.005_02.
10698 * doc/autoconf.texi (Special Shell Variables): Document some
10699 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10701 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10702 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10703 eval $LINENO is not portable in practice.

10722 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10723 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10724 POSIX decided to standardize on the int flavor of strerror_r.
10725 Always do char* test, as there's no reason not to.
10726 Assign to a char* var, to catch strerror_r that returns int*.
10728 * doc/autoconf.texi (Particular Functions):
10729 Document the above changes. Also, document the fact that
10730 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10732 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10734 2001-10-20 Akim Demaille <akim@epita.fr>

10750 * doc/autoconf.texi: Adjust.
10752 2001-10-20 Akim Demaille <akim@epita.fr>
10754 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10755 Remove, dead.
10756 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10757 `intl' is already present, as it refuses unless --force.
10758 (&parse_args): Use -I, --include instead of the old Autoconf
10759 options.
10760 ($localdir, $autoconf_dir): Remove.
10761 (@include): New.

10776 2001-10-19 Akim Demaille <akim@epita.fr>
10778 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a

10793 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10794 (AS_BASENAME_EXPR): New macro.
10795 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10796 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10797 and fall back on 'sed' only if the other two fail. This makes
10798 AS_BASENAME act more like AS_DIRNAME.
10799 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10800 contains white space.
10801 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10802 Use AS_DIRNAME, since I think it's now DOS-friendly.
10803 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10804 Allow "dirname //FOO" to return either / or //, as POSIX allows
10805 either behavior.

10809 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

10815 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

10855 bother with $force since...
10856 * lib/Autom4te/General.pm: does.
10858 2001-10-08 Akim Demaille <akim@epita.fr>
10860 * bin/autoreconf.in: Rewrite in Perl.
10861 * configure.ac: Adjust.

10947 ourselves with CONFIG_SHELL.
10949 2001-10-05 Paul Eggert <eggert@twinsun.com>
10951 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

11023 Don't use nested parenthesization. This patch was originally

11026 * doc/autoconf.texi (Limitations of Usual Tools):
11027 Clarify remark about sed and nested parenthesization.
11029 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):

11031 the type exists.
11032 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11033 Check for `expr' arithmetic overflow, and for compilation failure,
11034 and invoke a new argument $4 if either is discovered.
11035 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
11036 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

11068 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
11069 (AC_PROG_CPP requires AC_PROG_CC): here and...
11070 * tests/fortran.at (GNU Fortran 77): there.
11071 * doc/autoconf.texi (autoconf Invocation): Fix the example:
11072 AC_TRY_RUN is about compilation, not shell commands.

11078 Raja R Harinath:
11079 Be sure to detect when $LINENO always returns the same value.

11081 enough.
11082 Pass the CLI arguments to `$as_me.lineno'.

11177 * tests/Makefile.am (package.m4): Remove.
11179 2001-09-22 Akim Demaille <akim@epita.fr>
11181 Rely on `$LINENO' when possible instead of `__oline__'.
11183 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
11184 `$LINENO' support replacement when not supported.
11185 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
11186 them explicitly to be sure they are not output before this section
11187 (via m4_require). Cosmetic only.
11188 * lib/autoconf/c.m4, lib/autoconf/general.m4,
11189 * lib/autoconf/programs.m4: Replace all the occurrences of

11193 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
11195 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
11196 character (u: -> ue) in a code comment.
11197 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
11198 it works.
11200 2001-09-21 Akim Demaille <akim@epita.fr>
11202 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
11203 Suggested by Jim Meyering.

11212 * lib/autoconf/general.m4: Fix a small Englisho.

11214 setting up ac_dir_suffix and ac_top_builddir.
11215 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
11217 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

11220 PATH_SEPARATOR.
11221 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

11224 * lib/autotest/general.m4: Replace occurrences of ':' in
11225 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
11227 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11229 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
11230 arguments. Fixed a typo.
11232 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11234 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
11235 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
11237 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11239 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
11240 * bin/autoupdate.in: Ditto.
11241 * bin/autoheader.in: Reworded a few comments.

11246 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11248 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
11249 already have $file). Set output files to binary mode (helps avoid
11250 CR issues on DOSish systems).
11252 2001-09-19 Akim Demaille <akim@epita.fr>
11254 * lib/autotest/general.m4: Englishoes.
11255 From Tim Van Holder and Alexey Mahotkin.
11257 2001-09-18 Paul Eggert <eggert@twinsun.com>
11259 * doc/autoconf.texi (Common Shell Constructs): New node,
11260 documenting AS_DIRNAME.
11261 (Limitations of Usual Tools): Refer to it when discussing dirname.
11262 Also, update discussion of POSIX standard to reflect latest draft.
11264 * lib/autoconf/c.m4:
11265 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11267 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11268 Do not pass a first argument with leading '-'
11269 to expr, by parenthesizing initial integers that might be negative.
11271 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11272 now merely checks whether it is an error to pass an argument
11273 to getpgrp.
11275 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11276 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11277 whether it is a (compile-time) error to pass an argument to
11278 getpgrp. This simpler test supports the revised documentation,
11279 and is all that AC_FUNC_GETPGRP's users really need.
11281 2001-09-18 Akim Demaille <akim@epita.fr>
11283 * doc/autoconf.texi (Limitations of Make) <$<>: New.
11285 2001-09-18 Akim Demaille <akim@epita.fr>

11293 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11294 correctly.
11295 Add test for AS_BASENAME.
11296 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11297 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11298 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11299 * tests/base.at: Fixed the expected responses. The old ones were
11300 one line out...
11301 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11302 the documentation claims it should (and how it behaved in 2.13).
11304 2001-09-18 Akim Demaille <akim@epita.fr>
11306 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11307 the AC_CONFIG_COMMANDS invocation.
11308 This also solves the name clash problems.
11309 Don't set the package's ID.
11310 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11311 No longer to be shipped.
11312 (version.in): Remove.
11313 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11314 * lib/autoconf/status.m4: Adjust.
11315 Use `m4_PACKAGE_STRING'.
11316 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11317 the only optional argument is the name of the test suite.
11318 Expect `package.m4' to define the package signature.
11319 * lib/autom4te.in (Autotest): Add `package.m4?'.
11320 * tests/Makefile.am (package.m4): New.
11321 * tests/suite.at: ifnames is a victim.
11323 2001-09-18 Akim Demaille <akim@epita.fr>
11325 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11326 AC_LIBSOURCE, AC_CONFIG_FILES.
11327 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11328 program version string doesn't match the package's.
11329 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11330 after `(cached)'.

11334 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11335 Allow expression to return any value that can fit into unsigned long
11336 (not int, as before). Check for output errors.
11338 2001-09-17 Bruno Haible <haible@ilog.fr>
11340 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11341 Always include <stdio.h> and <stdlib.h>. Evaluate
11342 the expression in an extra function before these includes. Call
11343 fprintf "%d" only after ensuring the argument is of type 'int'.
11344 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11346 2001-09-17 Paul Eggert <eggert@twinsun.com>
11348 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11349 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11350 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11351 when they don't exist.
11353 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11354 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11355 need it.
11357 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11358 version with the version used by fileutils 4.1, except use
11359 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11360 we don't need it.
11362 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11364 2001-09-13 Akim Demaille <akim@epita.fr>
11366 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11367 _first_.
11368 Reported by Gerrit P. Haase.
11370 2001-09-13 Akim Demaille <akim@epita.fr>
11372 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

11392 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
11393 AT_tests_all for consistency.
11394 Set at_victims.
11395 (AT_VICTIMS): Similar to AT_KEYWORDS.
11396 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
11398 2001-09-13 Akim Demaille <akim@epita.fr>
11400 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
11402 2001-09-13 Akim Demaille <akim@epita.fr>
11404 * lib/autotest/general.m4 (AT_INIT): Create and remove
11405 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11406 test suites can cohabit.
11408 2001-09-13 Akim Demaille <akim@epita.fr>
11410 * tests/mktests.sh: Don't output banners for empty test files.
11412 2001-09-13 Akim Demaille <akim@epita.fr>
11414 Test suites can be run independently of configure.

11429 (Syntax of the shell scripts): Don't check ifnames.
11430 (AT_CHECK_PERL_SYNTAX): New.
11431 (Syntax of the Perl scripts): Check ifnames.
11432 * tests/ifnames: New.

11456 (m4_list_append): Remove.
11458 Spread a few keywords in the Autoconf test suite.
11460 2001-09-10 Akim Demaille <akim@epita.fr>
11462 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

11478 2001-09-07 Akim Demaille <akim@epita.fr>
11480 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
11481 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
11482 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
11483 related variables into `at_package_*'.

11495 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
11496 in addition, it introduces useless differences in logs.
11497 (AT_INIT): Let atconfig and atlocal be both optional.
11498 Adjust PATH computation.

11508 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'
11509 to avoid GCC warnings.
11510 From Uwe Seimet.
11512 2001-09-05 Akim Demaille <akim@epita.fr>
11514 * bin/autom4te.in: --language is -l, not -s.
11516 2001-09-05 Akim Demaille <akim@epita.fr>
11518 Be ready to handle filenames as stupid as `dnl.at', for if even
11519 the maintainer is dumb enough to do that...
11521 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11522 excellence in M4 quotation: consider `__file__' is active.
11524 And BTW, when invoking m4, pass the --include in the right order:

11555 New, extracted from main.
11556 Use IO::File wherever possible.
11557 (input.m4): Be constant, use -I instead of hard coding $tmp.

11559 Don't invoke `_au_disable', since ac was not loaded, but just

11562 2001-08-31 Akim Demaille <akim@epita.fr>

11574 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
11575 serious problems handling heredocs in heredocs.
11576 Reported by Nicolas Joly.
11578 2001-08-31 Akim Demaille <akim@epita.fr>
11580 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
11581 (Making testsuite Scripts): Update.
11583 2001-08-31 Akim Demaille <akim@epita.fr>
11585 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11587 2001-08-31 Akim Demaille <akim@epita.fr>
11589 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11590 (testsuite Scripts): There is no such thing as `atconfig.in'.
11591 And actually one diagram is missing: test suite runtime.
11593 2001-08-31 Akim Demaille <akim@epita.fr>
11595 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11596 inverse order.
11598 2001-08-31 Akim Demaille <akim@epita.fr>
11600 * bin/autoupdate.in (@include): `installcheck' revealed the path
11601 to m4sugar was lacking!
11603 2001-08-31 Akim Demaille <akim@epita.fr>
11605 * man/Makefile.am (.x.1): We really have to pass
11606 autom4te_perllibdir.
11608 2001-08-31 Akim Demaille <akim@epita.fr>
11610 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11611 debug scripts, in particular passing explicitly listed tests to
11612 run is stupid.
11614 2001-08-31 Akim Demaille <akim@epita.fr>
11616 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11617 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11618 Use directly autom4te, not autoconf.
11619 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
11621 2001-08-31 Akim Demaille <akim@epita.fr>
11623 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
11624 * bin/autoheader.in (%symbol): Strip arguments of macros.
11626 2001-08-31 Akim Demaille <akim@epita.fr>
11628 * doc/autoconf.texi: Catch up -I, --include changes.
11630 2001-08-31 Akim Demaille <akim@epita.fr>
11632 * bin/autom4te.in (&parse_args): Die on unknown languages.
11633 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
11634 need for autoconf.
11635 Promote --include over --macrodir and other obsolete options.
11637 2001-08-31 Akim Demaille <akim@epita.fr>
11639 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
11640 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
11641 * bin/autom4te.in ($autoconf): Pass --force.
11642 `print $out' doesn't print `$_' but `$out'.
11643 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11644 (autoheader): Pass --force since the test suite goes too fast for
11645 the time stamps.
11646 Adjust to the new autoheader messages.
11648 2001-08-31 Akim Demaille <akim@epita.fr>
11650 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11651 Check the completeness of the #template.
11652 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
11653 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
11654 invocation.
11656 2001-08-31 Akim Demaille <akim@epita.fr>
11658 * lib/Autom4te/General.pm (&find_file, &update_file): New.
11659 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11660 Drop AC_MACRODIR dead for real.
11661 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11662 `autoheader: `config.hin' is created'.
11663 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11665 2001-08-31 Akim Demaille <akim@epita.fr>
11667 * bin/autoheader.in: Rewrite in Perl.
11668 * tests/autoheader: Adjust.
11670 2001-08-31 Akim Demaille <akim@epita.fr>
11672 * bin/autoconf.in (--include, -I): New option.
11673 Map --localdir, --autoconf-dir onto it.
11674 Forward autom4te's options instead of interpreting them.
11675 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11676 There is no such envvar since the inception of autom4te.cfg.
11677 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11678 * bin/autoupdate.in: Adjust, and perform more control.
11679 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11680 * tests/autoconf: Dittowise.
11682 2001-08-31 Akim Demaille <akim@epita.fr>
11684 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11685 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11686 optionally `FILE'.
11687 Use -e, not -f, since /dev/null for instance is OK.
11688 (&parse_args): Adjust.
11689 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11691 2001-08-31 Akim Demaille <akim@epita.fr>
11693 * configure.ac: Also find tested executables in bin.
11694 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11695 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11696 installed peer executables, only PATH is allowed to resolve it.
11697 Pass `autoconf_dir' via options, not via invisible envvars.
11698 * lib/Autom4te/General.pm (&find_peer): Remove.
11699 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11700 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11701 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11702 find the executables for it.
11703 * tests/Makefile.am: Major cleanup. Too lazy to document...
11704 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11705 We only need PERL.
11706 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11707 indeed related to running the test suite, while passing
11708 --autoconf-dir and others is related to running non installed
11709 Autoconf executables. So don't do that, leave it to...
11710 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11711 * tests/autoscan: New.
11712 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11713 refer to library files: rely on --language.
11715 2001-08-29 Akim Demaille <akim@epita.fr>
11717 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11718 s/--set/--language/.
11720 2001-08-29 Akim Demaille <akim@epita.fr>
11722 * doc/autoconf.texi: Strip the @nodes.
11723 Suggested by Paul Eggert.
11724 (Initializing configure): Typo.
11726 2001-08-29 Akim Demaille <akim@epita.fr>
11728 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11729 Suggested by Paul Eggert.
11731 2001-08-29 Akim Demaille <akim@epita.fr>
11733 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11734 download in a tmp dir.
11736 2001-08-29 Akim Demaille <akim@epita.fr>
11738 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11739 case insensitive OSes out there :(
11740 From Tim Van Holder.
11742 2001-08-29 Akim Demaille <akim@epita.fr>
11744 * lib/autom4te.in: New.
11745 * lib/Makefile.am (edit, autom4te.cfg): New.
11746 * bin/autom4te.in (BEGIN): Simplify.
11747 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
11748 (&load_configuration): New. Use it.
11749 (&parse_args): Support --mode, --set, and --melt.
11750 * bin/autoconf.in: Simplify and adjust.
11751 * tests/Makefile.am (AUTOMAKE): Use --set.
11752 * tests/atlocal.in: Adjust.
11753 * BUGS: distcheck and check are weak.
11755 2001-08-29 Akim Demaille <akim@epita.fr>
11757 * lib/autotest/general.m4: Use
11758 foo=`(command) 2>/dev/null`
11759 not
11760 foo=`command` 2>/dev/null
11761 (at-devnull): Rename as...
11762 (AT-devnull): this.
11763 (--clean): Remove AT-* files too.
11764 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11765 Reported by Nicolas Joly.
11767 2001-08-28 Akim Demaille <akim@epita.fr>
11769 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

11771 Reported by Nicolas Joly.
11773 2001-08-28 Kevin Ryde <user42@zip.com.au>
11775 * doc/autoconf.texi (Function Portability): Mention C right shifts.
11777 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
11779 * lib/autotest/general.m4: Reword some messages.
11780 (AT_INIT): Check for the `times' builtin before using it.
11781 Support test ranges as arguments to the testsuite.
11782 Have -e imply -d as the help text suggested.
11784 2001-08-27 Akim Demaille <akim@epita.fr>
11786 * Makefile.maint: Formatting changes.
11787 (do-po-update, po-update, cvs-update, update): New targets.

11799 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11800 Support `VAR=VAL' as arguments.
11801 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
11802 may be set via the command line.
11804 2001-08-27 Akim Demaille <akim@epita.fr>
11806 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
11807 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
11808 first the build dirs, then the src dirs.

11811 2001-08-27 Akim Demaille <akim@epita.fr>
11813 * lib/autotest/general.m4 (AT_INIT): Output the definition of
11814 at_data_files earlier.
11815 (--clean, -c): New option.
11816 * tests/Makefile.am: Use this option.
11818 2001-08-27 Akim Demaille <akim@epita.fr>
11820 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11821 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11822 readable.
11823 Adjust callers.
11824 * doc/autoconf.texi (Configuration Actions): Document the vars
11825 available in commands.
11826 Emphasize the risks of collisions in init-cmds.

11830 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
11831 (Initializing configure): this new node.
11833 2001-08-27 Akim Demaille <akim@epita.fr>

11846 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

11856 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
11857 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
11858 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11859 -> ac_dir).
11860 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11861 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11863 2001-08-27 Akim Demaille <akim@epita.fr>

11889 (AMTAR): Help automake define it.
11890 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
11891 needed, 1.5 can have a macro and a target with the same name.

11893 * m4/strip.m4: New.

11906 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.

11908 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11909 the name of the directory they're in, instead of the filename,
11910 since version.m4 is now in m4sugar, but m4_acversion must not be
11911 classified as an Autoconf macro.
11912 ($input_m4): Don't qualify the path to m4sugar.
11913 Rather, pass autoconf_dir to m4.
11914 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
11915 * tests/suite.at: Require 2.52c.
11917 2001-08-27 Akim Demaille <akim@epita.fr>

11929 of config.log on traps.
11930 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
11931 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
11932 for config.status'.
11933 Open the log as soon as possible.
11934 Use the same log introduction as configure's.
11936 2001-08-22 Paul Eggert <eggert@twinsun.com>
11938 * doc/autoconf.texi (Indices): New node.
11939 Move indices out of the top level menu and into this submenu.
11941 2001-08-22 Akim Demaille <akim@epita.fr>
11943 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11944 AC_TRY_COMMAND.
11945 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.

11986 * configure.ac (AT_CONFIG): Fix the path.
11987 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
11988 can be used.
11990 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
11992 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
11993 program with AC_LANG_PROGRAM before feeding it to
11994 AC_COMPILE_IFELSE. Cleanup grep usage.
11996 2001-08-20 Akim Demaille <akim@epita.fr>
11998 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11999 * NEWS, README, README-alpha, TODO, tests/README: This package is
12000 `Autoconf', not `autoconf' (the executable).
12002 2001-08-20 Akim Demaille <akim@epita.fr>
12004 Info readers seem to need `Index' in the index node title :(
12006 * doc/autoconf.texi: Reverse the 2001-08-15 change which
12007 simplified index node names.

12051 2001-08-20 Akim Demaille <akim@epita.fr>
12053 Huh!?!?! There are still some user EOF tags used, which prevents
12054 their use in AC_CONFIG_COMMANDS for instance...
12056 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
12057 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

12120 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
12121 `$0.log' as for projects where testsuite is in src, we'd have
12122 testsuite.log created in src.

12136 2001-08-17 Akim Demaille <akim@epita.fr>
12138 * doc/autoconf.texi: Work around Texinfo buglets.
12139 (Transformation Rules): One example is enough, users are expected
12140 to have their brains on. And BTW, use DESTDIR.
12141 (dvar): New macro. Use it.
12143 2001-08-17 Akim Demaille <akim@epita.fr>
12145 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

12159 2001-08-16 Paul Eggert <eggert@twinsun.com>
12161 * doc/autoconf.texi, doc/install.texi: Put copyright notice at

12164 2001-08-15 Akim Demaille <akim@epita.fr>
12166 * doc/Makefile.am (fu): New index, can't use fn because of defmac.
12167 Use it.
12169 2001-08-15 Akim Demaille <akim@epita.fr>

12178 * doc/install.texi: Use @command.

12185 value.

12191 (local-check): Run changelog-check. last.
12192 (alpha): Don't depend upon local-check, since...
12193 (cvs-dist): depends upon it.
12195 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
12197 * tests/Makefile.am: Use a clean-local rule to remove
12198 autom4te.cache (it's a directory, not a file.
12199 * Makefile.am: Ditto (but maintainer-clean-local).
12201 2001-08-15 Akim Demaille <akim@epita.fr>
12203 * bin/autom4te.in (@m4_warning): New.
12204 (&handle_m4): Use it.
12205 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12206 warnings are issued at each run.
12207 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12208 is in the src tree.
12210 2001-08-15 Akim Demaille <akim@epita.fr>
12212 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
12213 don't waste time running `autoupdate --version' works.
12214 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
12216 2001-08-13 Akim Demaille <akim@epita.fr>
12218 * doc/autoconf.texi (ma): Rename this index as...

12241 * doc/autoconf.texi, doc/install.texi: Add a copyright notice

12271 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
12273 * tests/semantics.at (AC_C_BIGENDIAN): New test.
12275 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12277 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12278 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12279 * doc/autoconf.texi (C Compiler Characteristics): Update
12280 documentation for AC_C_BIGENDIAN.
12282 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12284 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12285 magic values from an object file when cross-compiling.
12286 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12288 2001-08-10 Akim Demaille <akim@epita.fr>
12290 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12291 effects.
12292 Suggested by Russ Allbery.
12294 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12296 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12297 current $prefix to the sub-configures.
12299 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12301 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12302 extension (needed on BeOS). Reported by Guido van Rossum.
12304 2001-08-09 Akim Demaille <akim@epita.fr>
12306 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12308 2001-08-07 Akim Demaille <akim@epita.fr>
12310 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12311 removed.
12312 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12313 No need to remove the files before and after the each test, before
12314 each test and at the end of the suite is enough.
12315 Display only the children `times', not the shell's.
12316 If the test failed or was skipped, at-times is not available.
12318 2001-08-07 Akim Demaille <akim@epita.fr>
12320 Always produce testsuite.log, including when there are no
12321 failures. This helps getting information on skipped tests, and
12322 duration of the tests. Err, implement the latter btw.
12324 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12325 Dump information on the first run of each test.
12326 (AT_CLEANUP): Create `at-times' containing the duration of the
12327 test group.
12329 2001-08-07 Akim Demaille <akim@epita.fr>
12331 The use of `dumpstat' revealed that `len' was used although it
12332 should not. m4_text_wrap was using it, but in the Autoconf world
12333 where it is legal. Hence (i) test M4sh in its own world, not
12334 Autoconf's, and (ii), ahem, fix the bug :)
12336 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12337 does not like `' instead of [].
12338 (AT_INIT): Forbid `^_?AT_'.
12339 And don't output such tokens.
12340 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12341 `script.as', and `autom4te.cache'.
12342 Remove `empty' and `macro' which are no longer used.
12343 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12344 * tests/m4sugar.at: Use it.
12345 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12347 2001-08-07 Akim Demaille <akim@epita.fr>
12349 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12351 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12353 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12355 2001-08-04 Akim Demaille <akim@epita.fr>
12357 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12358 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12359 AC_TRY_LINK.
12360 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12361 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12362 (AC_F77_MAIN): Likewise.
12364 2001-08-04 Akim Demaille <akim@epita.fr>
12366 Don't rely on M4sugar outputting the patterns in files, since we
12367 might process the output _without_ running m4, hence without these
12368 files.
12370 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12371 * bin/autom4te.in (@Request::includes): Remove, unused.
12372 (@Request::source): Rename as...
12373 (@Request::input): this.
12374 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12375 (&handle_output): Fetch the patterns from the traces.
12376 `$forbidden' and `$allowed' are constant: use m//o.
12377 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12378 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12380 2001-08-04 Akim Demaille <akim@epita.fr>
12382 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12383 autoconf', i.e., in addition to caching traces, cache the output.
12385 * bin/autom4te.in (Request::cache): Rename as...
12386 (Request::id): this.
12387 ($cache, $icache, $tcache, $ocache): New.
12388 (&handle_m4): Save M4 output in the cache instead of $tmp.
12389 (&handle_output): Adjust.
12390 (&up_to_date_p): Check that the output cache is up to date too.
12391 (top level): Run `&handle_m4' iff force or the cache is invalid.
12392 Run `&handle_output' if the output cache is more recent.
12394 2001-08-04 Akim Demaille <akim@epita.fr>
12396 * bin/autom4te.in ($force): New.
12397 (&parse_args, &print_usage): -f, --force is a new option.
12398 (&handle_output): CPP directives might have spaces after `#'.
12399 (&parse_args): The first file only can be frozen.
12401 2001-08-04 Akim Demaille <akim@epita.fr>
12403 Don't let autom4te compute the `include' traces several times:
12404 first check that the trace cache file is up to date, and then
12405 compare its timestamp with that of the output.
12407 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12408 the preamble. Don't require 5.005 as Autom4te::General does it,
12409 and better yet (use `use', not `require'!).
12410 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12411 Class::Struct as Autom4te::Struct.
12412 * lib/Autom4te/General.pm (File::stat): Use it.
12413 (&mtime): New, export it.
12414 * bin/autom4te.in: Use it.
12415 Declare `$req' is invalid if it is outdated.
12416 Don't declare it valid before saving it if something went wrong.
12418 2001-08-04 Akim Demaille <akim@epita.fr>
12420 Autom4te shall not encode Autoconf data, and preselecting traces
12421 must be proposed to the users.
12423 * bin/autom4te.in (@required_trace): Remove.
12424 (@preselect): New.
12425 (&parse_args, &print_usage): -p, --preselect is a new option.
12426 (&up_to_date_p): Adjust.
12427 * bin/autoconf.in: Preselect some Autoconf macros.
12429 2001-08-04 Akim Demaille <akim@epita.fr>
12431 * tests/tools.at (autoconf --trace: user macros): Check traces on
12432 macros invoked without arguments, and macros invoked with multiple
12433 lines arguments.
12435 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
12437 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
12438 arguments.
12440 2001-08-03 Akim Demaille <akim@epita.fr>
12442 * bin/autoconf.in ($@): Work around the usual sh bug.
12443 From Nicolas Joly.
12445 2001-08-03 Akim Demaille <akim@epita.fr>
12447 Clean up the handling of the M4 builtins tracing exception.
12449 * bin/autom4te.in (Request::request): Don't complete M4 builtins
12450 trace requests.
12451 (@m4_builtins): Rename as...
12452 (@m4_builtin): this.
12453 (%m4_builtin_alternate_name): New.
12454 (&parse_args): Complete the trace requests with alternate names.
12455 (&handle_traces): Hence no longer do it here.
12456 (&trace_requests): Remove, unused.
12458 2001-08-03 Akim Demaille <akim@epita.fr>
12460 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
12461 m4_if, and m4_wrap.
12463 2001-08-03 Akim Demaille <akim@epita.fr>
12465 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
