13 define HAVE_INT8_T, and likewise for similar macros.
14 Problem reported by Patrick Welche in
15 <http://lists.gnu.org/archive/html/autoconf/2007-05/msg00062.html>.
17 2007-05-25 Noah Misch <noah@cs.caltech.edu>
19 * bin/Makefile.am ($(top_builddir)/bin/autom4te): New dependency.
21 2007-05-21 Paul Eggert <eggert@cs.ucla.edu>
23 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp

105 section titles and other comments; no code change.
107 2007-05-01 Kevin Ryde <user42@zip.com.au>
109 * doc/autoconf.texi (Particular Programs): Typo
110 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
112 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
114 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that

122 Bruno Haible.
124 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
126 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
127 for a.* when searching for executables, as this prevents users
128 from having files like a.c. Problem reported by Ralf Wildenhues in:
129 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
130 This fixes a problem introduced on 2000-12-19.

134 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
135 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
136 via Bruno Haible.
138 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
140 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
141 AC_CHECK_TYPE, AC_CHECK_TYPES.
142 * doc/autoconf.texi (Generic types): C types must be type-names
143 (the C terminology), not type-ids (the C++ term). C++ types
144 must not be anonymous.
145 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
146 for C++; this drops support for anonymous struct and union types,
147 which were problematic anyway.
148 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
149 for C++.
151 2007-04-12 Jim Meyering <jim@meyering.net>

159 Report by Pallav Gupta <pallavgupta@gmail.com>.
161 2007-04-11 Paul Eggert <eggert@cs.ucla.edu>
163 * doc/autoconf.texi (Generic Types): Document the restrictions
164 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
165 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
166 with objects too. Document the restrictions on its use.
167 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
168 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
169 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
170 works but the latter doesn't, then it's a valid type.
171 This lets people use function types and so forth.
172 For C++ there doesn't seem to be a simple solution, so leave it alone.
173 (AC_CHECK_SIZEOF): Allow argument to be a variable.
174 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
175 AC_CHECK_TYPE; that wasn't documented or necessary.
177 2007-04-11 Stepan Kasal <kasal@ucw.cz>
179 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
180 when cross-compiling.

192 2007-04-06 Paul Eggert <eggert@cs.ucla.edu>
194 * doc/autoconf.texi (Particular Types): AC_C_LONG_DOUBLE is now
195 obsolescent. Suggested by Bruno Haible.
196 * NEWS: Document this.
198 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
200 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
201 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
202 default still has the problem. Problem reported by Bruce Korb.
204 2007-03-28 Stepan Kasal <kasal@ucw.cz>
205 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

222 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
223 checks for unsigned long long int.
225 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
227 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
228 nonstandard grep R.E. escape sequences.
230 2007-03-17 Jim Meyering <jim@meyering.net>
232 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
233 (Limitations of Usual Tools): Also list \< and \>, and mention that
234 HP-UX's grep, like the one from Solaris, does not support that syntax.
236 2007-03-09 Stepan Kasal <kasal@ucw.cz>
238 * doc/autoconf.texi (Specifying Names): `--host' does not
239 change the build type.
241 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
243 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
244 suggests AC_CONFIG_HEADERS.
245 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using

253 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
254 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
255 universal binaries. Problem reported by Elias Pipping.
257 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
259 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
260 * doc/autoconf.texi (C Compiler): Document this. There is a new
261 extra argument ACTION-IF-UNIVERSAL.
262 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
263 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
264 Reindent for sanity's sake.
266 2007-02-24 Eric Blake <ebb9@byu.net>

274 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
276 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
277 status of rm so we know when it failed.
278 If cleaning of test dir failed before running the test, warn.
279 Output the line separator in verbose mode before the warning
280 to make clear the warning belongs to the following test.
282 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

291 errors introduced in last change.
293 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
295 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
296 an actual carriage return. Use "ac_cr" to contain the actual
297 carriage return.
298 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
299 with traditional Awk and begin.
300 * tests/torture.at (Limitations of Builtins): Document the problem

307 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
308 input from /dev/null in awk test, so even Solaris /usr/bin/awk

330 2007-01-31 Eric Blake <ebb9@byu.net>
332 * THANKS (people): Update.
334 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
336 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
337 latest version.
338 (Shell Substitutions): Note problems with @{var:=value} etc.
339 Add a new section for problems with @{#var} etc. Problem noted
340 by Ralf Wildenhues. See:

343 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
345 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
346 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
347 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
348 substitution will still be done by the special code.
349 Report by Jim Meyering.
351 * doc/autoconf.texi (File System Conventions): Mention that
352 $PATH_SEPARATOR is for the build system only.
353 Report by Keith Marshall.
355 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

361 carriage return for $AWK, needed for BSD awk.
362 * tests/torture.at (Substitute and define special characters):
363 Test all 8 bit non-NUL characters.
364 Report against Automake by Patrick Welche.
366 2007-01-15 Stepan Kasal <kasal@ucw.cz>
368 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
370 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
372 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
373 early on the reader side, drop stderr of the input to avoid
374 `broken pipe' error output; this may happen even with shell
375 builtin `echo' of some bash versions. Reports by Ian Macdonald
376 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
378 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
380 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
381 separate items of `ac_user_opts', to avoid long lines.

390 Fix some wording problems noted by Paolo Bonzini in:
391 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
392 * doc/autoconf.texi (Signed Overflow Examples): Give more
393 discussion about the allow_superuser_privileges example,
394 and change it a bit to make things clearer.
395 (Optimization and Wraparound): Clarify whether the compiler
396 will generate an infinite loop for the example derived from
397 Autoconf's mktime test.
398 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
399 Also, clarify unsigned multiplication overflow.
401 2007-01-04 Eric Blake <ebb9@byu.net>
403 * bin/Makefile.am (RELEASE_YEAR): New macro.
404 (edit): Use it to supply correct copyright year to scripts.
405 * bin/autoconf.as (version): Use it.
406 * bin/autoheader.in ($version): Likewise.
407 * bin/autom4te.in ($version): Likewise.
408 * bin/autoreconf.in ($version): Likewise.
409 * bin/autoscan.in ($version): Likewise.
410 * bin/autoupdate.in ($version): Likewise.
411 * bin/ifnames.in ($version): Likewise.
413 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
415 * doc/autoconf.texi (Integer Overflow): Revised based on today's
416 feedback. The most important changes document what happens when
417 you convert an out-of-range value to a signed integer type, and
418 say that (sum < a) != (b < 0) reliably detects overflow when sum =
419 a + b.
421 * doc/autoconf.texi (Integer Overflow): Greatly expand and
422 rewrite, taking notions from the recent discussion on the gcc and
423 autoconf mailing lists; please see
424 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
425 and follow the many links.
426 (Integer Overflow Basics, Signed Overflow Examples):
427 (Optimization and Wraparound, Signed Overflow Advice):
428 (Signed Integer Division): New sections.
430 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
432 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
433 preprocessor macro arguments in traced name.
434 * doc/autoconf.texi (Defining symbols): Document longstanding
435 support for AC_DEFINE-ing macros with arguments, and document
436 behavior when the same variable has multiple AC_DEFINEs.
437 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
438 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
439 macros directly, giving much shorter and simpler code.
441 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
443 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
444 space before "$ac_configure_args" to prevent a 'config.status
445 --recheck' failure if ac_configure_args doesn't contain a leading
446 space. This works around a problem with the XEmacs configure.ac,
447 which uses the (undocumented) ac_configure_args variable
448 inconsistently with Autoconf.
450 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
452 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
453 Include <limits.h>, and use its INT_MAX to rewrite the
454 j loop so that it does not overflow 'int'. Problem reported by
455 Ralf Wildenhues in
456 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
457 Play it safe by shifting left by 1 rather than multiplying by 2,
458 as GCC is less likely to optimize this away when the value
459 is signed (when it assumes overflow leads to undefined behavior).
460 Also, don't assume time_t uses two's complement.
462 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
464 * tests/torture.at (Substitute a 2000-byte string): Avoid using
465 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
466 dumps core on it. Report by Tim Rice.
468 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
470 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
471 --disable-option-checking to --help output even when
472 AC_PRESERVE_HELP_ORDER is not used.
473 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
474 --with argument, rather than argument with [-.] replaced by
475 underscores.
476 * NEWS: Fix typo in previous change; the news was in the
477 wrong section.
479 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
481 * NEWS: Warnings are now generated by default for unknown
482 --enable-* and --with-* options.
483 * doc/autoconf.texi (Option Checking): Renamed from
484 (Configure Option Checking). Tighten up the wording a bit.
485 (External Software, Package Options): Cross-reference to Option
486 Checking, and use this to shorten our section.
487 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
488 "$x" to test "x$foo" != x.
489 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
490 Don't warn if $enable_option_checking is "no".
491 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
492 ac_unrecognized_opts to the empty string.
493 Don't echo the unrecognized opts, as this might mishandle
494 backslashes or leading -.
495 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
496 usage next to the other --disable-FEATURE options in the
497 help string.
499 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
501 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
502 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
503 Print warning for unrecognized --with and --enable options
504 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
505 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
506 Disable option checking when subdirs are configured.
507 (AC_OUTPUT): If warnings are enabled, print warning about
508 unrecognized --with and --enable options at the end of
509 the configure output (as well as at the beginning).
510 * doc/autoconf.texi (Option Checking): New node.
511 Document new option warning functionality.
513 2006-12-16 Eric Blake <ebb9@byu.net>
515 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
516 * NEWS: Start news for current version.
518 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
520 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
521 Define HAVE_GETMNTENT to 1, not to the empty string.
522 Problem originally reported by Jochen Friedrich in
523 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
525 This change prompted by a problem report by Andrey Simonenko in
526 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
527 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
528 object-like macros only, in the traditional portable character
529 set.
530 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
531 Warn about attempts to define things that are not identifiers.
532 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
533 awful hack that AC_DEFINEd macro names containing parentheses.
535 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
537 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
538 too drastic, even if Texinfo in theory requires it for info mode.
540 (config.status Invocation): Renamed back from Recreating a
541 Configuration).
542 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
543 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
545 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
547 * NEWS: Version 2.61a.
549 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
550 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
552 * NEWS: Document changes with echo and printf, and the lack
553 of limits on the total size of multi-line values of substituted
554 variables, and the AC_FUNC_FSEEKO fix.
556 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
558 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
559 Writing configure.ac.
560 (Autoconf Input Layout): Renamed from configure.ac Layout.
561 (Recreating a Configuration): Renamed from config.status Invocation.
562 (Obsolete Recreation): Renamed from Obsolete config.status Use.
563 (acconfig Header): Renamed from acconfig.h.
564 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
565 (Writing Testsuites): Renamed from Writing testsuite.at.
566 (Autom4te Cache): Renamed from autom4te.cache.
568 * BUGS: Remove mention of VPATH problem, since it's now documented
569 not to be a bug in the Autoconf build procedure itself, but rather
570 a problem with the proprietary `make' programs.
572 * doc/autoconf.texi (Build Directories): Add a cross reference
573 to VPATH and Make.
575 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
576 * doc/standards.texi: Sync from gnulib.
578 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
579 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
580 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
581 generated automatically.
583 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
585 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
586 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
587 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
589 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
591 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
592 `CEOF$ac_eof' special marker, the awk script cannot contain a
593 line matching `^CEOF', so this is not needed any more.
594 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
595 special marker in the test.
597 2006-12-06 Stepan Kasal <kasal@ucw.cz>
599 * tests/tools.at (autom4te preselections): Use `find -newer';
600 remove one of the sleeps.
602 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
603 more readable, using ...
604 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
606 * doc/autoconf.texi (autoheader Invocation): Do not double-
607 quote the parameter of `AH_BOTTOM' in the example.
609 2006-12-05 Stepan Kasal <kasal@ucw.cz>
611 * doc/autoconf.texi (Configuration Headers): Remove the
612 example with multiple input files.
613 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
614 multiple input files.
616 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
618 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
619 creating the awk substitution script, handle one input line at a
620 time, so that the maximum length of a substituted (multi-line)
621 value is not limited by the size of the sed pattern space.
622 The trade-off is a slightly repetitive sed script.
623 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
624 can only have up to 7 characters, due to Solaris 10 /bin/sed.
625 * tests/torture.at (Substitute a 2000-byte string): Increase the
626 test with several long lines, they should not be caught by sed
627 limits any more.
629 * tests/tools.at (autom4te preselections): New test, to flag
630 entries missing from autom4te.cfg.
631 Report by David Byron <dbyron@hheld.com>.
633 * tests/torture.at (Substitute a 2000-byte string): Actually use
634 AC_PROG_AWK, so the last change works as intended.
635 (Substitute and define special characters): Likewise.
636 (Substitute a newline): Likewise.
638 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
639 instead of `awk' consistently.
640 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
641 * tests/torture.at (Torturing config.status): Test both the
642 result of AC_PROG_AWK and plain awk.
643 (Substitute a 2000-byte string): Likewise.
644 (Substitute and define special characters): Likewise.
645 (Substitute a newline): Likewise.
647 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
649 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
650 can be assigned to a function pointer. Problem reported by
651 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
652 part of a patch by Ralf Wildenhues in that same bug report.
654 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
656 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
657 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
659 2006-12-01 Eric Blake <ebb9@byu.net>
661 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
662 cross-compiling from cygwin to mingw.
663 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
664 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
665 to lib/autoconf/c.m4.
667 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
669 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
670 string for more reliable failure. Wrap the entire test that
671 causes the broken Solaris printf to dump core, in a subshell,
672 so the segmentation fault message is reliably suppressed.
673 Fix shell expansion errors by using /usr/ucb/echo always;
674 avoid an error on systems without it by another subshell.
675 Avoid m4 expansion of `$1'. Set the zeroth argument of the
676 subshell-$as_echo to `as_echo', for better error message.
678 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
680 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
681 `BASH_SOURCE' contain a newline, set them to empty, as they may
682 not be unset.
684 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
686 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
687 years and is too hard to maintain now. The last straw was
688 reported by Jerker Baeck in
689 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
690 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
691 * doc/autoconf.texi (Particular Functions): Move
692 AC_FUNC_SETVBUF_REVERSED from here...
693 (Obsolete Macros): ... to here. Say that it does nothing now.
694 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
695 Turn into (almost) a no-op.
697 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
698 (AC_C_VOLATILE):
699 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
700 These macros are obsolescent and new applications shouldn't need them.
701 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
702 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
703 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
704 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
705 (AC_FUNC_VPRINTF): Likewise.
706 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
707 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
708 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
710 * doc/autoconf.texi (Setting Output Variables): Mention that
711 @VAR1@VAR2 has unspecified behavior. Problem reported by
712 Ralf Wildenhues.
713 * NEWS: Mention this.
715 * Makefile.am: Put only a single '#' into the copyright notice,
716 so that it's also present in the output file. Standardize wording
717 in makefile copyright notices to match GNU coding standards.
718 * bin/Makefile.am: Likewise.
719 * doc/Makefile.am: Likewise.
720 * lib/Makefile.am: Likewise.
721 * lib/freeze.mk: Likewise.
722 * lib/autoconf/Makefile.am: Likewise.
723 * lib/autoscan/Makefile.am: Likewise.
724 * lib/autotest/Makefile.am: Likewise.
725 * lib/m4sugar/Makefile.am: Likewise.
726 * man/Makefile.am: Likewise.
727 * tests/Makefile.am: Likewise.
728 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
729 one-line file.
731 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
733 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
734 in the sed script that mangles the awk script: delete up to the
735 first exclamation mark only.
736 * tests/torture.at (Substitute and define special characters):
737 Test '!' too.
739 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
741 Rewrite config files generation: avoid quadratic growth in
742 the number of substituted variables by using awk instead of sed
743 for the bulk of the substitutions.
744 * NEWS: Mention this.
745 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
746 forbidden in the output (and thus input) file.
747 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
748 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
749 generate just one large awk script for substitutions,
750 eliminating much of the earlier complexity, while adding some
751 new complexity. Only expand the substitution templates at
752 configure time, for smaller configure script size. If
753 _AC_SUBST_FILES are used, test 'awk' for working getline support
754 at config.status time. If absent, interpolate through the
755 shell. The awk script was written with much help
756 from Paolo Bonzini and Paul Eggert.
757 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
758 (_AC_SED_FRAG_NUM): Likewise.
759 (_AC_SUBST_CMDS): Renamed from...
760 (_AC_SED_CMDS): ...this.
761 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
762 * tests/torture.at (Substitute a 2000-byte string): Also
763 substitute a line with 1000 words, and a variable with several
764 long lines.
765 (Substitute and define special characters): Test awk special
766 characters, and put substitution input strings `@foo@' in the
767 output, to test that no recursion happens; test several other
768 combinations from Paolo Bonzini.
770 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
772 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
773 that replaced echo with AS_ECHO where this wasn't necessary.
774 Problem reportd by Ralf Wildenhues.
775 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
776 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
777 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
779 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
781 * lib/freeze.mk (GREP): Removed, no need to initialize this.
783 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
785 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
786 that traditional Awk lacks 3-arg "split". It has it.
787 Mention that FS must be a single character, and a few other
788 99-byte limits of traditional Awk.
789 Mention that if (i in a) doesn't work with traditional Awk.
791 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
793 * tests/autotest.at (BSx641-newline in command):
794 (BS-BS-newline in command, BSx640-newline in command):
795 (Newline-CODE-BS-newline in command):
796 (Single-quote-BS-newline in command):
797 (Single-quote-newline-BS-newline in command):
798 Use printf '%s\n' instead of echo, for portability to hosts
799 where echo interprets backslashes. This will break on hosts
800 that lack printf, but for now let's assume all such hosts
801 are dead (if not, we should get reports of test failures).
803 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
805 'echo' has some portability problems, when given a first argument
806 with a leading '-', or when given any argument containing '\'.
807 Avoid using 'echo' in these cases.
808 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
809 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
810 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
811 * lib/autotest/general.m4 (AT_INIT): Likewise.
812 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
813 argument might be unportable.
814 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
815 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
816 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
817 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
818 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
819 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
820 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
821 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
822 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
823 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
824 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
825 (AC_PROG_MAKE_SET): Likewise.
826 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
827 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
828 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
829 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
830 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
831 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
832 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
833 * bin/autoconf.as: Redo verbose flag implementation, as the old
834 scheme wouldn't work with AS_ECHO.
835 * lib/autotest/general.m4 (AT_INIT): Likewise.
836 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
837 Don't use ECHO_T, since ECHO_N is now reliable.
838 * lib/autotest/general.m4 (AT_INIT): Likewise.
839 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
840 rather than using a here-document to put the script into a file.
841 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
842 use AS_ECHO.
843 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
844 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
845 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
846 bug, but we might as well stop using ECHO_N and ECHO_C internally.
847 * lib/autotest/general.m4 (AT_SETUP): Likewise.
848 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
849 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
850 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
851 operand, as AS_ECHO requires. Avoid double file name expansion.
852 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
853 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
854 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
855 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
856 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
857 Double-quote strings that would otherwise contain M4 comments.
858 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
860 * configure.ac (AC_INIT): Bump to 2.61a.
861 * NEWS: Likewise.
863 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
865 Version 2.61.
867 * configure.ac (AC_INIT): Bump to 2.61.
868 * NEWS: Likewise.
870 * tests/autotest.at (Macro with backslash in a test title):
871 Comment out for now, as this tests neither fails nor passes
872 reliably. Problem reported by Ralf Wildenhues.
874 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
876 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
877 in previous change, which caused test failures.
879 2006-11-16 Stepan Kasal <kasal@ucw.cz>
881 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
882 code for --enable, --disable, --with, and --without to...
883 (_AC_INIT_PARSE_ENABLE): ... a new macro.
884 * doc/autoconf.texi (Package Options):
885 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
887 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
889 Import these changes from config via gnulib:

914 Import this change from gnustandards via gnulib:
916 2006-11-15 Karl Berry <karl@gnu.org>
918 * standards.texi: core -> memory, throughout.
919 (CPU Portability): show correct example of calling write
920 on a char value; thanks to Paul Eggert for the code.

924 Import these changes from texinfo via gnulib:
926 2006-11-08 Karl Berry <karl@gnu.org>
928 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and
929 as well as pdf images, since they are supported in pdftex with
930 no further ado.
932 2006-11-05 Karl Berry <karl@gnu.org>

946 first argument may also contain dots.
948 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
950 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
951 benefit of platforms like Solaris+GCC where it is common to have a
952 non-working g++ installation.

964 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
965 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
966 Imported from a similar patch to gnulib by Bruno Haible.
968 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
970 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

994 argument. Extend to check titles printed by ./micro-suite and
995 ./micro-suite -l and the title in micro-suite.log.
996 (Backquote in a test title,
997 Single-quote in a test title,
998 Double-quote in a test title): Don't expect failure anymore.
999 (Backslash in a test title): Put a non-whitespace character after the
1000 backslash so that Bourne shells might actually see it as an escape
1001 sequence.
1002 (Brackets in a test title,
1003 Pound in a test title,
1004 Comma in a test title,
1005 Quoted Macro in a test title,

1012 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
1013 The visible effect was a stray [] in the testsuite output.
1015 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1017 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
1018 `trap ... 0' inside a function, for AIX sh.
1020 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1022 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1023 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1024 5363) simply issues a warning when dividing by zero at compile
1025 time. Problem reported by Elias Pipping.
1027 2006-10-26 Eric Blake <ebb9@byu.net>
1029 * THANKS: Update.
1030 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1031 show effect on macros that expand with commas.
1032 Reported by Joel E. Denny.
1034 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

1059 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1060 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1061 reported by Nelson H. F. Beebe for Coreutils 6.4.
1063 * tests/tools.at (autoconf --trace: user macros): Remove test
1064 for tracing multiline macros, since m4 1.4.7a uses a different
1065 way to number lines. Problem reported by Ralf Wildenhues.
1067 2006-10-24 Stepan Kasal <kasal@ucw.cz>
1069 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1070 /dev/null since the heuristics for interactive behaviour was
1071 fixed in CVS m4.
1073 * bin/autom4te.in: With --force, always refresh the output
1074 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

1095 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1096 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

1127 looking for special shell characters.
1128 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
1129 macro defined by AS_VAR_PUSHDEF before passing it as a
1130 parameter.

1141 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1143 (Imported from Automake.)
1144 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1145 which incorrectly sets the mode of an existing destination
1146 directory. In some cases the unpatched install-sh could do the
1147 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1148 system. We hope this is rare in practice, but it's clearly worth
1149 fixing. Problem reported by Alex Unleashed in
1150 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1151 Also, don't bother to check for -m bugs unless we're using -m;
1152 suggested by Stepan Kasal.

1160 is enabled by default with gnu and gnits strictness.
1161 Report from Bruno Haible.
1163 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
1164 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
1165 gnu and gnits modes.
1167 Import this change from Config:
1169 2006-09-20 Ben Elliston <bje@gnu.org>

1172 Import this change from Gnulib:
1174 2006-09-16 Karl Berry <karl@gnu.org>
1175 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
1176 to avoid sectioning errors.

1189 * build-aux/texinfo.tex (\textdegree): New command.
1191 2006-08-12 Karl Berry <karl@gnu.org>

1196 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
1198 2006-10-13 Stepan Kasal <kasal@ucw.cz>
1200 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1201 added to the template can get mangled.
1203 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1205 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1206 include the default headers, and redefine obstack_chunk_alloc
1207 and obstack_chunk_free. Fixes false failure with glibc.
1209 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1211 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
1212 for backward compatibility with Libtool 1.5.22. Problem reported
1213 by Ralf Wildenhues.
1215 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1217 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
1218 AC_PROG_CC.

1228 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1229 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1230 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1231 Use a better substitute, by inspecting the output of "ls"
1232 rather than just using ":".
1233 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1234 rather than AS_EXECUTABLE_P, since we needn't worry about
1235 non-regular files here.
1237 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1238 due to configuration hassles with this. See Tonya Underwood's report
1239 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

1250 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1251 initialization which is not inherited through the environment
1252 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1253 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1255 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1257 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1258 problems with mkdir -p -m.
1260 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1262 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1263 comment about ac_cpp_err; it was incorrect, and anyway
1264 ac_cpp_err is being removed below.
1265 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1266 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1267 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1268 nobody uses it.
1269 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1270 with werror_flag and conftest.err and so forth. This is more
1271 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1272 and anyway the user shouldn't normally want to see this gorp logged.
1273 Problem reported by Ralf Wildenhues.
1274 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1275 empty, not 'no', since the rest of the code uses 'test -z'.
1277 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1279 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1280 Use a single call to AC_DO_TOKENS rather than multiple, for
1281 efficiency.
1282 (_AC_LINK_IFELSE): Test that resulting file is executable.
1283 Problem reported by mwoehlke in
1284 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1286 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1287 than creating a file to use with test -x; this is much faster.
1289 2006-10-02 Bruno Haible <bruno@clisp.org>
1291 * lib/autom4te.in (Automake-preselections): Add
1292 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1294 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1296 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1297 standard error, `experr' should be used, not `expout'.
1299 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1301 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1302 fseeko testing program twice; just use the earlier result.
1303 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1304 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1305 still doesn't let the program compile.
1306 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1307 failed.
1309 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1310 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1311 include it, without including anything else.
1312 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1313 expressions.
1314 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1316 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1318 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1319 `error.h', and include it, for a `error_at_line' prototype.
1320 Use a nonempty format string in the link test.
1321 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1322 for a declaration of wait3.

1331 values. Problem reported by Ralf Wildenhues.

1418 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
1420 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
1421 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
1422 for the existence of the directory at configure-time. That's
1423 too late, anyway. Problem reported by Stefan Seefeld.
1425 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
1426 7.1.4 /usr/bin/posix/sh described by Tim Rice in
1427 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
1429 2006-09-11 Stepan Kasal <kasal@ucw.cz>
1431 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
1432 works with GNU M4 1.4.3 again; make the normalized form
1433 match the current m4 message; fix the description.
1434 * test/tools.at (autom4te cache): Adapt to the change.
1436 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
1438 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
1439 to catch glibc bug 2821
1440 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
1442 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1443 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1444 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
1445 assume C89.

1459 2006-09-05 Paul Eggert <eggert@cs.ucla.edu>
1461 * doc/autoconf.texi (Preset Output Variables): srcdir and
1462 top_srcdir are not necessarily relative. Problem reported
1463 by Dries Kimpe.
1465 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1467 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1468 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1469 accept files with extension `.f'. For consistency, also prefer
1470 xlf over f77.
1471 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
1472 from last patch.
1474 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

1489 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
1491 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
1492 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
1493 except the first two arguments are reversed.
1494 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1495 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
1496 caches nor outputs a diagnostic. Suggested by Bruno Haible.
1497 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
1498 equivalent to the old AC_COMPUTE_INT.
1499 (AC_COMPUTE_INT): No longer caches or reports. New signature.

1501 * tests/base.at (AC_CACHE_CHECK_INT): New test.
1502 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
1504 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
1506 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
1507 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
1508 programs should use their Gnulib counterparts.
1509 * doc/autoconf.texi (Particular Functions): Likewise.
1510 (Macro Names, testsuite Invocation): Replace uses of these
1511 obsolete macros with uses of non-obsolete macros.

1521 mistakenly swapped on 2006-08-15.
1523 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
1525 * NEWS: Version 2.60a.
1527 2006-08-25 Stepan Kasal <kasal@ucw.cz>

1535 simplify the code.
1537 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
1539 Fix Lex library problem reported to us by Julio Garvia.
1540 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
1541 for the default, which the user can override.
1542 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1543 deal with LEXLIB.
1544 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1545 didn't work if some values were cached but not others. Test for
1546 broken lex libraries like native ia64-hp-hpux11.22; see
1547 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1548 work around the problem by preferring an empty LEXLIB to -lfl or
1549 -ll. Let the user set LEXLIB='' to indicate no library needed.
1551 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1552 * README: Likewise.
1553 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
1555 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>

1654 * doc/autoconf.texi (Particular Programs): Mention that
1655 @INSTALL@ and @MKDIR_P@ may vary for different output files.
1656 Reported by Alexandre Duret-Lutz.
1658 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
1660 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
1661 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
1662 Bill Northcott in
1663 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
1665 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>

1671 longer supported by Sun.
1673 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>

1677 -Wundef -Werror". Problem reported by David Fang in
1678 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1679 * doc/autoconf.texi (Header Templates, Default Includes):

1694 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1695 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1696 this.

1700 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1701 problems with arg script text that doesn't end in newline, and

1712 to last change.
1714 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1716 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1717 --help' should mention that `--version' outputs configuration
1718 settings. Report by Bruno Haible.
1720 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1722 Fix test suite failures reported by Pierre in
1723 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.

1738 less skeptical about "volatile", after discussion with
1739 Bruno Haible on bug-gnulib.
1740 (Limitations of Usual Tools): Warn about sed stripping
1741 leading white space from text. From Bruno Haible.
1743 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1745 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1746 compiler complains about it, even if things works after the
1747 complaint. Problem reported by Peter O'Gorman.
1749 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1750 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1751 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1753 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1755 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1756 after -R regardless of host. Patrick Welche reports that this
1757 fixes things on NetBSD 3.99.

1760 * README: Likewise.
1761 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

1763 to match M4 1.4.5.
1765 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1767 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1768 under AC_C_VOLATILE.
1769 (Volatile Objects): Be a little less skeptical about what
1770 "volatile" means. Derived from thoughts by Ben Pfaff in
1771 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1773 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1777 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1779 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1780 more globally, since the 2006-06-30 patch didn't suffice. Problem
1781 reported by Keith Marshall. Also, don't bother with builddir2,
1782 since it shouldn't be needed any more.
1784 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1786 * doc/autoconf.texi (Generic compiler characteristics):
1787 Document AC_COMPUTE_INT. Fix wrong statements on Default
1788 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1790 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.

1803 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1805 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1806 Require that long long int be at least 64 bits wide. C99 requires
1807 this and enough programs depend on it so we should check for it.
1808 Bruno Haible reports in
1809 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1810 that long long int is 32 bits wide with some nonstandard compilers.
1811 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1813 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1815 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1816 to a nonexistent file, so that we don't have to worry about
1817 a local site configuration that doesn't use /usr/local.
1818 Problem reported by Keith Marshall in
1819 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1821 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1823 * doc/autoconf.texi: Be more consistent about using @acronym with
1824 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1825 quite right (it talked about "OSF/Tru64", even though the
1826 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1827 and it even mentioned "OSF 4"!) and at this point there's little
1828 reason to talk about OSF any more, since it died in 1994.
1829 (Specific Compiler Characteristics): Simplify example of
1830 negative-size array.
1831 (File Descriptors): Reorder to make the text flow better.
1832 Remove joke about "appreciate the various levels"; I didn't get it.
1833 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1834 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1835 (File Descriptors, Limitations of Usual Tools):
1836 Tone down the advice against renaming or removing open files.
1837 (Limitations of Usual Tools): Add a new section, on 'rm'.
1839 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1841 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1842 -lXt in LIBS, idea from Karsten Hopp; this was due since
1843 this change:
1845 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1846 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1847 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1848 (which belong to Xt, not X itself). See Debian bug 327655.
1850 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1852 * configure.ac (AC_INIT): Bump to 2.60a.

1861 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1863 * config/texinfo.tex: Sync from upstream.
1865 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1866 quadrigraph correctly in traces.
1868 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1869 Fix typos.
1871 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1872 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1873 not defined.
1874 * doc/autoconf.texi (Changed Directory Variables): New node,
1875 to document the whole `datarootdir' business a bit better.
1876 * NEWS: Update.
1877 * tests/torture.at (datarootdir workaround): Extend test.
1878 Prompted by report by Alexandre Julliard.
1880 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1882 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1883 when using default mode of IBM C 6 for AIX. Problem and two-line
1884 fix reported by Larry Jones.
1886 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1888 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1889 about literal '${datarootdir}' if a definition is found in the
1890 output file.
1892 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1894 * NEWS: Use "M4" rather than "m4" when appropriate.
1895 Problem reported by Eric Blake.
1896 * doc/autoconf.texi: Likewise.
1897 Use @acronym around BSD, GCC, and GNU when appropriate.
1898 (Why GNU M4): Renamed from "Why GNU m4".
1899 (Redefined M4 Macros): Mention that Posix
1900 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1901 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1902 to int.
1904 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1906 * bin/autom4te.in (handle_output): Do not forbid the empty
1907 pattern.
1908 * tests/tools.at (autoconf: the empty token): New test.
1910 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1912 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1913 calls, so that we do not care whether they are LIFO or FIFO;
1914 in the m4_wrap, do not check which diversion is the topmost
1915 one, just check that the stack is balanced at the end.
1916 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1917 base diversion forever--pop the previous diversion before
1918 opening the new one; consequently, remove the m4_wrap call.
1919 * lib/autotest/general.m4 (AT_INIT): Likewise.
1920 * tests/m4sugar.at: Do not use
1921 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1923 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1924 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1926 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1927 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1928 Rework example of m4wrap token-pasting trouble so that it doesn't
1929 care whether it's LIFO or FIFO.
1930 Fix some "contrary to"s that are awkward in English.
1932 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1934 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1935 to `yes' instead of `int$1_t' if the type is found, for more
1936 consistent configure output (where $1 is the number of bits).
1937 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1938 Suggested by Bruno Haible.
1940 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1941 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1942 with system headers. Report by Bruno Haible.
1944 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1946 * config/config.guess, config/config.sub: Sync from upstream.
1948 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1949 in order to avoid picking up an older installed frozen m4sh.m4f.
1950 Besides an outdated shell startup, this could have been created
1951 by an earlier M4 version with incompatible frozen file format.
1953 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1955 * README: Recommend m4 1.4.4 instead of 1.4.3..
1956 * doc/autoconf.texi: Likewise.
1957 (Special Chars in Names): Say that $(.FOO) is portable, as
1958 suggested by Stepan Kasal.
1959 (Installation Directory Variables, Build Directories):
1960 (Automatic Remaking, Subdirectories, Fortran Compiler):
1961 (Making testsuite Scripts, Defining Directories):
1962 Quote variable usages better.
1963 (Making testsuite Scripts): Add clean-local rule to makefile
1964 snippet, by Eric Blake.
1965 (Installation Directory Variables): Fix table item font.
1966 Reword slightly to clarify. Generalize advice about
1967 not using special characters to include all file-related
1968 vars, not just VPATH.
1969 (Special Chars in Variables): Warn about special characters in
1970 $(srcdir) too.
1971 (Assignments): Clarify default-value example as suggested by
1972 Ralf Wildenhues in
1973 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1974 (Special Shell Variables): Note leading ./ or ../, as suggested
1975 by Eric Blake.
1976 (Limitations of Builtins): Under cd, warn about CDPATH.
1977 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1978 Ralf Wildenhues.
1980 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1982 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1983 `@var', for texi2html.
1984 (Systemology): Some more word wrapping, for DVI output.
1985 (autom4te Invocation): The short option for `--melt' is `-M',
1986 not `-m'.
1988 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1990 * doc/autoconf.texi: More formatting and English tweaks,
1991 many suggested by Ralf Wildenhues.
1992 Reword to avoid "@code{...}'s" and the like, since it's ugly
1993 with Emacs info mode. discontents -> woes.
1994 Put a few "will"s back. time stamp -> timestamp.
1995 side-effect -> side effect.
1997 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1999 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2000 Warn about $@ not persisting. Problem reported by Julien Danjou in
2001 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2002 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2003 Mention other special chars, too.
2005 2006-06-14 Eric Blake <ebb9@byu.net>
2007 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2009 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2011 * doc/autoconf.texi: Some systematic minor improvements, as
2012 follows. Use "makefile" when talking about makefiles
2013 generally (which might be named "makefile" or "Makefile" or even
2014 "foo.mk"), "Makefile" when talking about a specific makefile
2015 called "Makefile". This unclutters the text from weird quotes
2016 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2017 values" rather than "@var{foo}s" and similar constructs containing
2018 "}s". Use "Make rules" rather than "Makefile rules". Minor
2019 English-language improvements. Change the prefix "sub-" to "sub"
2020 and "re-" to "re".
2021 Put blank lines around examples more consistently.
2022 Avoid "rather" and "very" as intensifiers.
2023 Avoid "will" as an auxiliary.
2024 (Limitations of Make): Split this node into....
2025 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2026 (Leading _ in Macro Names, Backslash-Newline-Newline):
2027 (Backslash-Newline Comments, Long Lines in Makefiles):
2028 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2029 (obj/ and Make, make -k Status, VPATH and Make):
2030 (VPATH and Double-colon, $< in Explicit Rules):
2031 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2032 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2033 New nodes, resulting from splitup of Limitations of Make.
2034 All cross-references changed. Raise the top node from
2035 a section to a chapter, and all subnodes accordingly.
2036 Redo the introductory wording to match the new organization.
2037 (Installation Directory Variables): Use an example that is
2038 closer to what Autoconf actually does. Mention that VPATH's
2039 value should not contain metacharacters or white space.
2040 (Fortran Compiler): Fix a VPATH bug in an example.
2041 (Leading _ in Macro Names): Mention that this problem is no longer
2042 of practical concern.
2043 (VPATH and Make): Reword the advice to make it clearer
2044 that Autoconf and Automake support VPATH in non-GNU make, but
2045 many packages have bugs in this area.
2046 ($< in Explicit Rules): Refer to Build Directories rather
2047 than using a (non-VPATH-safe) example.
2048 (Automatic Rule Rewriting): Mention the sort of disaster that
2049 can ensue with Solaris-style rule rewriting with VPATH.
2051 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2053 * doc/install.texi (Compilers and Options): Weaken the
2054 suggestion to use GNU make for VPATH builds.
2056 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2057 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2059 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2060 in regular expression.
2062 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2064 * doc/autoconf.texi (Installation Directory Variables):
2065 Drop extra @samp from `@table @samp' item.
2066 (Limitations of Usual Tools): Comment fix.
2067 Do not nest @samp just to point to other table items.
2068 (Writing testsuite.at) <AT_CHECK>: The second argument to
2069 `@dvar' is already @samp'ed.
2070 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2071 do not use @var in the second argument.
2073 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2075 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2076 $as_shell.exe too. Problem reported by Andreas Buening in
2077 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2079 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2081 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2082 `unused variable' compiler warning, for `-Wall -Werror'.
2083 Reported by Jaap Haitsma in
2084 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2086 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2088 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2089 case the compiler dumps core. Problem reported for
2090 OpenServer 5.0.7 by Tim Rice in
2091 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2092 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2093 Likewise.
2095 2006-06-06 Tim Rice <tim@multitalents.net>.
2097 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2098 "ERROR" only shows up in "make check" output if there is an
2099 error.
2101 2006-06-06 Eric Blake <ebb9@byu.net>
2103 * tests/tools.at (automatically allowed tokens): Fix typo.
2105 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2107 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2109 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2110 typically overflows on x86 CPUs, even though the C standard
2111 requires otherwise.
2113 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2115 * configure.ac (AC_INIT): Bump to 2.59e.
2116 * NEWS: Update.
2118 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2120 Version 2.59d.
2122 * config/texinfo.tex: Sync from upstream.
2124 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2125 seen, invoke libtoolize with `--ltdl' argument.
2126 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2127 * NEWS: Update.
2128 Suggested by Eric Blake.
2130 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2132 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2133 reported by Ralf Wildenhues.

2149 * tests/base.at: Check AC_REQUIRE's error message.
2150 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2151 to...
2152 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2153 AT_CHECK_M4.
2154 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2155 `expout' as the last parameter.
2156 * tests/tools.at: Adapt to the above change.
2158 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2160 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2161 information about race-free implementations of mkdir.
2163 2006-06-04 Eric Blake <ebb9@byu.net>
2165 * bin/autoreconf.in (help): Document M4 environment variable.
2166 * bin/autoconf.as (Usage): Likewise.
2167 * bin/autom4te.in (help): Likewise.
2168 * doc/autoconf.texi (autom4te Invocation): Likewise.
2170 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2172 * NEWS: GNU make now recommended for VPATH builds.
2173 Mention that some macros are now documented to be obsolescent.
2174 * doc/autoconf.texi:
2175 Prefer "current" to "modern" to describe
2176 currently-used (albeit perhaps old-fashioned) hosts.
2177 Mention which ancient features no longer need to be worried about.
2178 setgid -> set-group-ID
2179 setuid -> set-user-ID (these are the Posix terms)
2180 Fix some misuses of "only".
2181 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2182 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2183 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2184 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2185 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2186 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
2187 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
2188 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2189 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2190 Mention that these macros are obsolescent.
2191 (Installation Directory Variables): shall -> should
2192 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2193 Mention that it's now safe to use 3 and 4.
2194 (Limitations of Usual Tools): cp -r is now specified by Posix.
2195 Omit longwinded and obsolescent discussion of cp -f.
2196 Modernize discussion of expr, ls.
2197 (Limitations of Make): Modernize discussion of VPATH builds.
2198 Mention $? as a workaround in some cases.
2199 * doc/install.texi (Basic Installation):
2200 Mention "./configure; make; make install" first. Be more
2201 specific about why this file is generic. Remove unnecessary
2202 parens. Remove misleading "only". Remove obsolete advice
2203 about csh. Don't say "configure" takes awhile; say it
2204 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2205 and CC=c99 rather than CC=c89, as these are blessed by current
2206 Posix. Recommend GNU make if doing a VPATH build.
2208 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2210 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2211 examples involving shell prompts.
2213 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2214 and Paul Eggert <eggert@cs.ucla.edu>
2216 * doc/autoconf.texi (Here-Documents): Add details about the
2217 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2218 use "here-documents" instead of "here documents".
2220 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2222 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2224 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2226 * doc/autoconf.texi (File System Conventions): Warn about ":"
2227 anywhere in directory names.
2229 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2231 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2232 about quoting the case statement, just in case.
2233 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2234 was fixed in ksh93g; reported by Ralf Wildenhues.
2236 2006-05-31 Stepan Kasal <kasal@ucw.cz>

2241 Document that ${MKDIR_P} understands --.
2242 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2243 comment.
2245 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2247 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2248 argument with leading hyphen. Problem reported by Paul Eggert.
2250 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2252 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2253 about quoting ac_try: quote all of it, if any of it seems suspicious.
2254 This means we don't have to worry about ${ or sed any more.
2255 Also, double-quote the case statement, to work around misuses via
2256 underquoting as reported by Ralf Wildenhues in
2257 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2258 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2259 undocumented and dangerous macro.
2260 Problem reported by Ralf Wildenhues in
2261 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2263 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2265 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2266 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2267 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2269 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2271 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2272 since evidently some packages rely on the old, broken behavior.
2273 Problem reported by Ralf Wildenhues in
2274 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2275 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2276 pre-2006-05-26 definitions, but leave in the comments that
2277 these macros are dangerous and should not be used.
2278 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2279 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2280 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2281 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2282 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2284 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2286 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2287 the use of 'tr', since this is our only use of 'tr'.
2289 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2290 and Paul Eggert <eggert@cs.ucla.edu>
2292 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2293 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2295 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2297 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2298 the output file in the `${datarootdir}' test.
2300 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2301 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2303 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2304 mention of `datarootdir' in the input file(s), but literal
2305 `${datarootdir}' in the output file, and we haven't warned yet,
2306 then warn as well: the user may have (erroneously) used
2307 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2308 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2309 * tests/torture.at (datarootdir workaround): Extend this test.
2310 * NEWS: Update.
2312 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2313 and Paul Eggert <eggert@cs.ucla.edu>
2315 * doc/autoconf.texi (autoheader Invocation): The first argument to
2316 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2317 alternatives and clear up the language a bit.
2319 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2321 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2322 ac_config_guess, ac_config_sub, ac_configure.
2323 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2324 Fix typo that prevented an unnecessary space from being removed.
2325 Problems reported by Ralf Wildenhues in:
2326 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2328 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2330 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2331 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2332 Don't use the term "thread-safe" to talk about mkdir race
2333 conditions, since the problem is more a process than a thread
2334 issue. Problem reported by Stepan Kasal in:
2335 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2336 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2337 the test for 'install' more closely. Look at MKDIR_P first.
2338 Look in the PATH, and at /opt/sfw/bin.
2339 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2340 Don't bother to try mkdir -p, since we already check mkdir --version;
2341 just look at the version number. (There's no easy way to check
2342 for race-free implementations.)
2343 * tests/tools.at (autoconf: subdirectories): Adjust to above
2344 changes, since MKDIR_P now might end in "/mkdir -p".
2346 * doc/autoconf.texi (autoheader Invocation): Mention that the
2347 first arg of AC_DEFINE_UNQUOTED must be a literal.
2348 Problem reported by Ben Pfaff in
2349 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2351 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2352 * doc/autoconf.texi (Special Chars in Variables): New section.
2353 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2354 (Installation Directory Variables): Quote $(datadir) better.
2355 (Limitations of Builtins): Describe some of eval's trickiness.
2357 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2358 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2359 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2360 in front of every arg, not just trailing args. Quote apostrophes.
2361 (_AC_EVAL_ECHO): New macro.
2362 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2363 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2364 removed.
2365 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2366 exposed by quoting of eval argument. Put the command on line line
2367 so it logs better.
2368 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2369 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2370 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2371 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2372 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2373 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2374 Use eval more safely.
2375 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2376 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2377 to be replaced.
2378 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2379 lines, exposed by quoting of eval argument.
2381 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2382 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2384 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2385 initialization of `ac_cv_exeext', do not override it if it was
2386 already set, unless it was set to `no', for compatibility with
2387 Autoconf-2.13, and comment this.
2388 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2389 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2390 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2391 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2392 Document that this test may be overridden by setting
2393 `ac_cv_exeext'.
2395 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2397 Revert these two patches:
2399 2006-04-06 Eric Blake <ebb9@byu.net>
2400 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2401 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2402 2006-04-01.
2404 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2405 Clean up _AC_COMPILER_EXEEXT* macros.
2406 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2407 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2408 ac_file to the name of the default output file and call
2409 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2410 initial `rm' of the candidate files...
2411 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2412 the same list in subsequent `rm' calls, and for the temporary
2413 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2414 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2415 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2416 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2417 no longer needed) by libtool. Make it a cache check.
2418 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2419 copied here by mistake.
2420 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2421 _AC_COMPILER_EXEEXT.
2422 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2423 _AC_COMPILER_OBJEXT directly.
2424 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2426 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2428 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2429 Fix description of how the buggy `sed' works.
2431 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2433 Sync from Automake:
2435 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2436 ENOLCK. Only mention `make -j' when applicable. Only raise
2437 fatal errors when `make -j' is involved. Improve error message.
2439 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2441 * doc/autoconf.texi (Here-Documents): We now know more about
2442 the variable expansion in here documents bug.
2443 Thanks to Tim Rice and Stepan Kasal.
2445 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2446 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2448 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2450 * tests/autotest.at (Multiline command from M4 expansion):
2451 No failure to be expected if the shell quotes newlines in
2452 commands in the `set -x' output. Report by Tim Rice.
2453 * THANKS: Update.
2455 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2457 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2458 expansion in the here-documents used by config.status, as that
2459 runs afoul of the Korn shell version M-12/28/93d bug described in
2460 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2461 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2462 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2464 2006-05-23 Jim Meyering <jim@meyering.net>
2466 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2467 Fix typo introduced with 2006-04-02 change. It reversed the sense
2468 of the test.
2470 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2472 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2473 ac_dB slightly, to save bytes in the script.
2474 Max out at 50 lines, rather than 96; this is more likely
2475 (though not guaranteed) to avoid obscure 'sed' failures.
2477 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2479 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2480 `tr -d -' as bad option argument. Work around this by deleting
2481 an unrelated character.
2482 Report by Tim Rice <tim@multitalents.net>.
2484 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2485 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2486 Stepan Kasal <kasal@ucw.cz>
2488 * doc/autoconf.texi (Particular Programs): Do not promise that
2489 we always prefer the GNU version of the program, and that we
2490 search according to PATH; both rules can have exceptions.
2491 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2492 AC_PROG_SED. Move descriptions of limitations
2493 to the Limitations of Usual Tools section.
2494 (Limitations of Usual Tools) <sed>: Mention script length
2495 limitations with Solaris /usr/ucb/sed.
2496 <grep>: Fix wording for empty alternative. Mention that -c and
2497 -l should not be combined, and that -E and -F should not be
2498 combined.
2500 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2501 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2503 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2504 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2506 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2508 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2509 AC_DEFINE is now passed to m4_pattern_allow.
2510 * NEWS: Mention that; likewise for AC_SUBST.
2511 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2512 the parameter to m4_pattern_allow.
2513 * tests/tools.at: Add a check for that.
2515 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2517 * lib/autoconf/status.m4: Fix typos.
2519 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2521 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2522 only the files that this macro generates.
2524 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2526 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2527 the HP-UX sed limitation of 99 commands, labels do not count.
2528 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2529 in the comment.
2530 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2532 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2534 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2535 Import the following fix from coreutils:
2537 2006-01-13 Jim Meyering <jim@meyering.net>
2539 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2540 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2541 not double-quote uses of that variable, to accommodate the rare
2542 case in which getmntent is available in none of the libraries
2543 checked. This happens at least on FreeBSD 5.0.
2545 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2547 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2548 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2549 some other programs unwisely rely on these undocumented vars.
2550 But put in warning comments about them.
2551 Problem reported by Ralf Wildenhues in
2552 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2553 * NEWS: Document that these variables are intended to go away.
2555 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2557 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2558 and set the language to C++ (analogous to the equivalent Fortran
2559 tests).
2561 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2562 * doc/autoconf.texi (C++ Compiler): Document it.
2563 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2564 * NEWS: Update.
2566 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2568 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2569 that caused config.status to generate 100-command sed scripts; the
2570 portable limit is 99.
2572 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2574 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2575 variable `ac_d' instead of `d' to avoid infringing namespace.
2576 Report by Ralf Menzel.
2578 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2580 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2581 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2582 * tests/tools.at (autoconf: subdirectories): New test, taken from
2583 the corresponding problem report by Ralf Wildenhues in:
2584 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2586 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2587 Quote some uses of shell variables if they might suffer unexpected
2588 globbing. This doesn't fix all instances of quoting problems that
2589 I found, just the easy ones that look safe.
2590 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2591 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2592 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2593 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2594 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2595 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2596 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2597 Likewise.
2598 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2599 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2601 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2603 * bin/autoreconf.in ($help): Reword according to the manual.
2604 Suggested by Olly Betts.
2606 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2607 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2609 * bin/autoreconf.in: Pass the directory argument to
2610 `require_configure_ac'. Fix comment.
2611 * tests/torture.at (Configuring subdirectories): Expose this.
2612 Reported by Olly Betts.
2614 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2616 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2617 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2618 Automake as follows:
2620 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2621 `$configure_in' instead of `configure.in', to preserve
2622 directory component.
2624 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2626 * config/config.guess, config/config.sub, config/texinfo.tex,
2627 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2629 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2631 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2632 test for C99 conformance; (bool) 0.5 is an integer constant
2633 expression, but (bool) -0.5 is not. Problem reported by Fedor
2634 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2636 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2638 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2639 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2640 Warn about obsolete install-sh files. Remove stray sentence
2641 fragment and fix cross reference.
2642 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2643 install -d; this undoes the 2006-05-10 change.
2644 (MKDIR_P): Mark with AN_MAKEVAR.
2645 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2646 that we don't require $INSTALL to be thread-safe. Move comments
2647 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2648 of AC_PROG_INSTALL. Output a message saying that we're checking
2649 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2650 MKDIR_P instead of AC_SUBST.
2651 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2652 Special magic for MKDIR_P, too.
2653 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2654 a dnl.
2655 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2657 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2659 Sync from Automake, as follows:
2661 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2662 * config/install-sh: Initialize IFS, so field splitting isn't
2663 turned off later.
2664 * config/mkinstalldirs: Likewise.
2665 * config/missing: Remove superfluous quotes. Replace all uses of
2666 `[' by `test', for consistency, and for..
2667 * config/missing (sed_minuso, sed_output): New variables.
2668 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2669 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2670 Fixes `missing' to detect `--output' for help2man. Fixes
2671 PR automake/483. Report by Dennis J. Linse.
2672 (autom4te): Document in `missing --help'.
2674 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2676 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2677 * config/install-sh: Don't use 'path' to talk about file names,
2678 as per GNU coding standards. Close a race condition reported by Ralf
2679 Wildenhues and Stepan Kasal. There is still a race condition
2680 on hosts that predate Posix 1003.1-1992, but we can't help this.
2681 Don't mishandle weird characters like space on pre-Posix hosts.
2682 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2683 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2684 AC_PROG_MKDIR_P from AS_MKDIR_P.
2685 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2686 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2687 earlier editions are not (including Automake 1.8.3).
2688 Do not suggest mkinstalldirs for thread-safety.
2689 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2690 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2691 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2692 presence of special characters and race conditions.
2693 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2694 in Autoconf's name space.
2696 2006-05-10 Bruno Haible <bruno@clisp.org>
2697 and Paul Eggert <eggert@cs.ucla.edu>
2699 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2700 from Automake with minor changes.
2701 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2703 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2705 * config/install-sh: Update to Automake CVS version, as follows:
2706 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2707 * lib/install-sh: Simplify the expr implementation of dirname.
2708 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2709 * lib/install-sh: Handle --, and diagnose unknown options.
2711 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2713 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2714 `./autom4te' to create `./testsuite', since the `all' target
2715 will ensure its presence, but `installcheck' should not create
2716 the uninstalled wrappers.
2718 * tests/torture.at (Unusual Automake input files): Skip if we
2719 detect automake < 1.8.
2721 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2723 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2724 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2725 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2726 * NEWS: Update.
2728 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2730 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2731 munge (multiple) white space and other oddities.
2732 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2733 single quotes in variable assignment.
2734 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2735 and similar failures by adding multiple spaces, tabs, and other
2736 special characters.
2737 Report and different test suggested by Francesco Romani
2738 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2740 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2741 single quotes, we only need to search for single quotes; this
2742 both simplifies the search pattern, and makes us less
2743 susceptible to `echo' variations for arguments not containing
2744 single quotes.
2745 (_AC_ARG_VAR_VALIDATE): Likewise.
2747 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2749 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2750 `$*' and IFS concatenation issue with traditional shells and

2763 and Bruno Haible <bruno@clisp.org>
2765 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2766 about 'od'.
2767 (Integer Overflow): Mention the special case of integer division
2768 overflow.
2770 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2772 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2773 traditional shells like the Solaris one that do not use the
2774 first IFS character for assembling `$*'.
2775 Prompted by a related report from autoconf_bug@nro.ca.
2777 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2778 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2780 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2781 Mention more problems with the -e option.

2797 `action-if-found' -> `action-if-true' and similarly.
2798 (Obsolete Macros): Likewise.
2799 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2800 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2801 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2803 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2805 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2807 * ChangeLog: Typo.

2824 with status 1, not merely nonzero. Clarify exit declaration.
2825 (Run Time): Move C exit status stuff to new Exiting Portably section.
2826 (Systemology): Mention Posix and levenez. Update v7 reference.
2827 (Portable Shell): Mention the Posix shell.
2829 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2831 * bin/autoconf.as (me): Replace by as_me.
2833 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2835 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2836 since as_me isn't set yet.
2838 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2840 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2841 a few minor bugs in this area.
2843 * doc/autoconf.texi (Programming in M4sh): Comment out the
2844 documentation of AS_BASENAME, for now.
2845 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2846 (Limitations of Builtins) <basename>: Do not refer to
2847 AS_BASENAME.
2848 * bin/autoconf.as (me): Don't use AS_BASENAME.
2849 (dir): Remove the unused variable.
2850 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2851 AS_DETECT_REQUIRED. All uses changed.

2853 All uses changed.
2854 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

2856 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2857 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2858 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2859 (_AS_DIRNAME_PREPARE): Likewise.

2864 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2866 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses

2869 * lib/autoconf/functions.m4: Likewise.
2870 * lib/autoconf/general.m4: Likewise.
2871 * lib/autoconf/headers.m4: Likewise.
2873 * doc/autoconf.texi (Run Time): Document the exit status situation
2874 with more accuracy and detail.
2876 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2878 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2879 Archive is not officially `GNU' any more. Update URL.
2880 (Defining Directories): Likewise
2881 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2883 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2885 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2886 newline from the `trap' code to finish `config.log'; the NetBSD
2887 /bin/sh resets the exit status after an empty command, as
2888 documented in doc/autoconf.texi.
2889 Reported by Dalibor Topic <robilad@kaffe.org>.
2891 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2893 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2894 Suggested by Bruno Haible.
2896 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2898 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2899 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2900 Instead, just list the shells that we know work.
2901 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2902 changed. Be more cautious about the _cv_ variable.
2903 * tests/tools.at (Syntax of the shell scripts): Check the
2904 _cv_ variable once, at first, to avoid an internal autoconf error
2905 when sh -n does not work.
2907 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2909 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2911 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2913 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2914 use ">&-" since we're only 99.999% sure that this is portable,
2915 and since the MinGW bug is fixed in a different way.
2916 * lib/autotest/general.m4 (AT_INIT): Likewise.
2918 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2920 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2921 before opening config.log, to avoid hitting a bug on MinGW.
2923 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2925 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2926 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2927 This works around a MinGW bug reported by Eric Paire.
2928 Make sure that all writes to the log file append to it,
2929 rather than possibly losing data.
2930 * lib/autotest/general.m4 (AT_INIT): Likewise.
2932 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2934 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2935 description.
2937 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2939 * NEWS: Update.
2941 * configure.ac (AC_INIT): Bump to 2.59d.
2943 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2945 Version 2.59c.
2947 * Makefile.maint (news-date-check): Do not require a leading `*'
2948 before the release date in NEWS.
2950 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2951 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2953 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2954 the instantiated file do not contain the string 'datarootdir'
2955 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2956 @mandir@, replace the reference '${datarootdir}' by the value.
2957 * tests/torture.at (datarootdir workaround): New test.
2958 * NEWS: Advertise this temporary fixup.
2959 Based on a patch by Bruno Haible, reported and analyzed by
2960 Paul Eggert and Noah Misch.
2962 2006-04-12 Eric Blake <ebb9@byu.net>
2964 * tests/autotest.at (Debugging a failed test): Fix comment.
2966 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2968 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2969 all the changes since 2006-04-07.
2971 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2973 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2974 succeeded, but `ln -s file dir' failed, take care to remove the
2975 leftover target before the next test, to prevent its spurious
2976 failure; also make sure `ln file dir' works before selecting it.
2977 Thanks to Keith Marshall for pointing this out.
2978 * THANKS: Update.
2980 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2981 assignments in `at_debug_args', so that we put them correctly
2982 in the `run' script.
2983 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2984 Reported by Eric Blake.
2986 2006-04-11 Eric Blake <ebb9@byu.net>
2988 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2989 top-level tests after micro-suite has been run. Used in...
2990 (Debugging a successful test, Debugging script and environment),
2991 (Debugging a failed test): ...these new tests. The first of these
2992 is fixed by...
2993 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2994 macro, split out from...
2995 (AT_INIT): ...here, so that using -d also generates a run script.
2996 Document that -d inhibits top-level logging.
2997 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2998 inhibits top-level logging; debug scripts are created.
3000 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3001 check.
3002 * tests/autotest.at (Empty test, Empty check): New test to check it.
3004 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3005 from gcc.
3007 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3009 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3010 the files if a problem appears. Make the empty *.at files
3011 read-only, too. Proposed by Ralf Wildenhues.
3013 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3015 * config/Makefile.am: Add comment to force updated Makefile.in.
3017 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3018 space only patch to this file, this patch causes the Makefile.in
3019 files that include freeze.mk to be updated, and thus have a
3020 newer time stamp again, which in turn makes a pristine CVS
3021 checkout have correct time stamps.
3023 * Makefile.maint (cvs-sv): New macro, to be used..
3024 (config.guess-url_prefix, config.sub-url_prefix)
3025 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3026 point to CVS text checkout of Gnulib files.
3027 (copyright-check): Bump current year.
3028 (announcement): Do not hard-wire `./announce-gen'.
3029 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3030 correctly.
3031 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3032 `chmod +x'.
3033 (wget_files): Update config.guess, config.sub, texinfo.tex by
3034 `wget-update', now that their URLs work again.
3036 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3038 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3039 Problem noted by Paul D. Smith.
3041 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3043 * doc/autoconf.texi: Remove unused words from word list.
3044 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3045 .x-sc_trailing_space: New files.
3047 * doc/standards.texi: Sync from gnulib.
3049 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3050 `LIBOBJDIR' as experimental.
3052 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3053 with a target directory; it's internally implemented as `cp'
3054 anyway, but since Autoconf advertises the possibility to use
3055 a target directory when LN_S is `ln -s', we need to find out.
3056 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3057 analyzed by Keith Marshall <keith.marshall@total.com>.
3059 * THANKS: Update.
3061 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3063 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3064 confdefs.h as-is. In general, if it has backslash-newline or the
3065 like, then it doesn't work either to sort or to remove empty
3066 lines.
3068 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3070 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3072 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3074 * lib/autom4te.in (Automake-preselections): Preselect
3075 _AM_SUBST_NOTMAKE.
3077 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3079 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3080 apostrophe within a single-quoted string, as this is the usual
3081 tradition and is easier to read than '"'"'. Don't rely on the
3082 shell treating "$/" like '$/'. Use a more-consistent indenting
3083 style for the trap.
3085 2006-04-09 Eric Blake <ebb9@byu.net>
3087 * tests/autotest.at (Backquote command substitution),
3088 (Multiline backquote command substitution): Remove mistaken
3089 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3090 applied...
3091 (Parenthetical command substitution, Multiline parenthetical
3092 command substitution): here.
3094 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3096 Import macros from gnulib (often changing their name).
3098 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

3110 (Pointers): Add Gnulib URL.
3111 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
3112 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3113 Gnulib section.
3114 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
3115 suggest a #define rather than a typedef for _Bool, and mention
3116 Gnulib rather than trying to substitute stdbool code.
3117 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
3118 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
3119 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

3122 headers too.
3123 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3124 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
3125 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
3126 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
3127 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3128 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3129 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3130 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3131 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3132 (Coding Style). Don't mention m4_expand_once.

3140 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
3141 (AC_HEADER_ASSERT): New macro.
3142 (AC_HEADER_STDBOOL): Don't assume "#error" works.
3143 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
3144 Catch a bug in an HP-UX C compiler.
3145 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
3146 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
3147 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

3150 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
3151 New macros.
3153 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
3154 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
3156 2006-04-08 Stepan Kasal <kasal@ucw.cz>
3158 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
3159 of the warning introduced by the 2001-08-28 change.
3161 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
3162 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3164 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'

3169 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3171 Revert the patch from 2006-04-01 and only improve
3172 _AS_DETECT_BETTER_SHELL:
3174 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3175 skip nonexistent directories.
3176 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3177 only shell candidates which exist.
3178 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3179 * lib/autotest/general.m4 (AT_INIT): No need to give three
3180 parameters to _AS_PATH_WALK.
3182 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3183 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3185 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3186 distinguish m4sugar macros.
3187 * tests/tools.at (autoupdating with aclocal and m4_include):
3188 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3189 test case by Noah Misch <noah@cs.caltech.edu>.
3191 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3193 Revert my change from 2006-03-17, in other words:
3194 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3195 and DUALCASE=1.
3196 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3197 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3198 it is set.
3200 2006-04-07 Eric Blake <ebb9@byu.net>
3202 * doc/autoconf.texi (Programming in M4sh): Document that
3203 AS_MKDIR_P exits the script on failure.
3204 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3206 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3208 * config/elisp-comp, config/install-sh, config/mdate-sh,
3209 config/missing, config/mkinstalldirs: Sync from Automake.
3211 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3212 from Automake.
3214 * doc/make-stds.texi: Sync from gnulib.
3216 2006-04-06 Eric Blake <ebb9@byu.net>
3218 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3219 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3220 2006-04-01.
3222 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
3223 Eric Blake <ebb9@byu.net>,
3224 Paul Eggert <eggert@cs.ucla.edu>,
3225 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3227 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3228 whether `set' quotes correctly: redirect stderr of the tested
3229 `set', and use a subshell, for Ultrix; use `sed' instead of
3230 `grep' for zsh `set' which may write binary output; match only
3231 at the beginning of a line, to avoid false positives.
3232 In order to avoid false positives by unrelated variables with
3233 multiline content, put the dump algorithm in a subshell and
3234 unset all variables containing newlines (except some which are
3235 special to the shell). Warn about cache variables that are
3236 unset.
3238 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3240 * config/config.guess, config/config.sub, config/texinfo.tex:
3241 Sync from upstream.
3243 * tests/mktests.sh: Reword comments.
3245 * tests/mktests.sh: Only skip internal macros starting with
3246 `_AC_' or `__AC_'. Noted by Stepan Kasal.
3247 Update exclusion lists for the test suite to this end:
3248 (AC_ARG_VAR): Do test this now.
3249 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3250 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3251 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3252 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3254 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3255 shell issue with double-quoted command substitutions of native
3256 commands.
3257 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
3258 Marshall.
3260 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
3261 no file matches the glob, discard the warning, set `nullglob'.
3262 (syntax-check): Likewise.
3263 (sc_cast_of_x_alloc_return_value): Likewise.
3264 (sc_cast_of_alloca_return_value, sc_error_exit_success)

3268 (sc_tight_scope): Do not fail for non-existing `src' directory.
3269 (sc_changelog): Skip the Copyright footer.
3270 * lib/autoconf/lang.m4: Remove trailing space.
3272 * lib/autoconf/status.m4: More replacements to
3273 <tab><space> where this makes sense.
3275 2006-04-06 Stepan Kasal <kasal@ucw.cz>
3277 * tests/Makefile.am (maintainer-check-posix):
3278 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
3280 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
3281 ac_config_<foo>s again, sometimes normalized, sometimes not.
3282 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3283 (AC_CONFIG_COMMANDS): Do not do so here.
3284 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3285 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3286 2005-07-25 rewrite. Noticed by Noah Misch.
3288 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3289 _AC_PRESERVE_HELP_ORDER, ...
3290 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3292 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3293 inside m4_expand_once; it is redundant.
3295 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3296 for --help from Cygnus `configure.'
3298 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
3300 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
3301 on a patch proposed by Ralf Wildenhues.
3303 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3305 * lib/autoconf/status.m4: Replace <space>''<tab> with
3306 <tab><space> where this makes sense.
3308 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
3309 Noah Misch <noah@cs.caltech.edu>
3311 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3312 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3313 * doc/autoconf.texi (Help Formatting): New node.
3314 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3316 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3318 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3319 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3320 lib/autoconf/types.m4, lib/autotest/general.m4,
3321 tests/mktests.sh, tests/torture.at: White space cleanup:
3322 remove some SPACE before TAB, or add quoting ('' or @&t@).
3324 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
3326 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
3328 2006-04-05 Eric Blake <ebb9@byu.net>
3330 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
3331 empty test suite works.
3332 * tests/autotest.at (Empty test suite): Remove xfail.
3334 2006-04-05 Noah Misch <noah@cs.caltech.edu>
3336 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
3337 TAGS to ac_config_<foo>s.
3338 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
3339 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
3340 normalizing it, consistent it with previous releases.
3341 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3343 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3345 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3346 Use simplified args that Eric Blake originally suggested.
3348 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3350 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3351 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3352 Use 'comm' rather than N instances of grep; this also fixes a bug
3353 whereby substrings were incorrectly matched, causing us to not
3354 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3355 (exclude_list): Exclude empty macros.
3356 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
3358 Use awk rather than grep -E or egrep, to avoid
3359 portability problems with regular expressions containing newlines.

3361 Switch from grep to awk syntax.
3362 (ac_exclude_script): Renamed from ac_exclude_egrep.
3363 (au_exclude_script): Renamed from au_exclude_egrep.
3365 2006-04-04 Noah Misch <noah@cs.caltech.edu>
3367 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
3368 a subdirectory subject to Cygnus `configure'.
3369 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3371 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3372 report request when we have no AC_PACKAGE_BUGREPORT.
3374 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3376 * THANKS: Update.

3379 generated files.
3381 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
3382 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
3383 typedef'ed restricted pointer, to catch a compiler bug on
3384 HP-UX 11.x, and fix warnings so it passes with -Werror.
3385 (_AC_PROG_CC_C99): Likewise.
3386 Reported by Albert Chin <china@thewrittenword.com>.
3387 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

3402 * THANKS: Add myself.
3404 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3406 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
3407 to log, point to testsuite output tree.
3409 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
3411 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
3412 * doc/autoconf.texi (Function Portability): Mention that C++
3413 has trouble with 'exit'.
3414 (Guidelines): Test programs shouldn't use 'exit'.
3415 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
3416 Remove; all uses removed.
3417 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

3437 Clean up _AC_COMPILER_EXEEXT* macros.
3439 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3440 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3441 ac_file to the name of the default output file and call
3442 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3443 initial `rm' of the candidate files...
3444 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3445 the same list in subsequent `rm' calls, and for the temporary
3446 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3447 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3448 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3449 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3450 no longer needed) by libtool. Make it a cache check.
3451 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3452 copied here by mistake.
3453 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3454 _AC_COMPILER_EXEEXT.
3455 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3456 _AC_COMPILER_OBJEXT directly.

3483 and fix some typos.
3485 2006-04-01 Noah Misch <noah@cs.caltech.edu>
3487 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
3488 Autoconf version number despite a zero- or one-argument AC_INIT.
3490 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
3491 subordinate tools.
3492 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
3493 * doc/autoconf.texi (autoreconf Invocation): Document it.
3495 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
3496 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

3502 rm failed to remove it.
3504 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3506 * bin/autoupdate.in: Redefine m4_location so that warnings print
3507 the correct lines of the input file by subtracting..
3508 (_au__first_line): ..this new definition.
3510 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
3511 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
3512 Remove stray newline in output.
3513 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
3514 AC_DEFUN this for autoconf, including the obsoletion diagnose.
3515 Fixes autoupdating of code where the replacement output contains
3516 m4sugar macros.
3517 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
3518 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

3520 * tests/tools.at: Several new tests for all of this.
3521 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
3522 hairy details.
3523 The AC_LANG_SAVE issue was reported against Libtool by
3524 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
3525 Kristian Kvilekval <kris@cs.ucsb.edu>.
3527 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3529 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3530 switch all of them on and of when necessary. Fixes the bug when
3531 m4sugar macros (e.g., m4_define) were expanded after the first
3532 automatic update (e.g., after AC_PREREQ or AC_INIT).
3534 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

3556 2006-03-30 Chris Pickett <cpicke@cs.mcgill.ca> (tiny change)
3558 * doc/autoconf.texi (autoreconf Invocation): Mention that -I for
3559 aclocal cannot be given on the command line.
3561 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
3563 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
3564 Give an example for AS_DIRNAME instead of referring to Posix..
3565 (File System Conventions): Put discussion of // versus / here, and
3566 modernize it a bit.
3567 (Limitations of Usual Tools): Add basename. Remove verbiage
3568 after dirname, since it got moved to the above sections.
3569 All this was inspired by a patch proposed earlier by Eric Blake.
3571 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3573 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Quote

3575 * lib/autotest/general.m4 (AT_INIT): Likewise.
3576 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Likewise, for
3577 `$0', $as_me.
3579 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3581 * bin/autoscan.in: The value of find_configure_ac should be
3582 checked for existence, so we don't barf over a nonexisting
3583 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
3585 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3587 * bin/autoupdate.in: Fix some typos.
3589 2006-03-21 Stepan Kasal <kasal@ucw.cz>
3591 * doc/autoconf.texi (Installation Directory Variables): Fix typo.
3593 * lib/autoscan/autoscan.list: Refreshed.
3595 2006-03-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4082 (Limitations of Usual Tools): Document the weird restrictions
4083 that Posix has about { }. Use better quoting.
4084 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_HEADER):
4085 Rewrite to conform to Posix rules about { } in sed scripts.
4086 * lib/m4sugar/m4sh.m4 (AS_DIRNAME_SED, AS_BASENAME_SED): Likewise.
4087 * tests/foreign.at (Libtool): Likewise.
4088 * tests/semantics.at (AC_CHECK_PROG & AC_CHECK_PROGS):
4089 Use our own style advice re 's,a,b,' versus 's|a|b|'.

4104 shell from zsh to bash.
4106 2005-12-31 Stepan Kasal <kasal@ucw.cz>
4108 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
4109 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
4111 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
4113 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced
4114 parentheses in $(...). Problem reported by Eric Blake.

4144 2005-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4146 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Pass
4147 CONFIG_SHELL in the environment of the configure rerun.
4148 * doc/autoconf.texi (Here-Documents, config.status Invocation):
4149 Suggest passing CONFIG_SHELL absolute, and in the environment
4150 rather than as option.
4152 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4154 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

4168 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4170 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
4171 Factor functionality to..
4172 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
4173 `AC_SUBST($1)' in the public version.
4174 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
4175 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
4176 ac_pt_* variables.
4178 2005-11-01 Stepan Kasal <kasal@ucw.cz>
4180 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
4181 filesystems.
4183 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4187 2005-10-27 Stepan Kasal <kasal@ucw.cz>
4189 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
4190 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4192 2005-10-25 Stepan Kasal <kasal@ucw.cz>
4194 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
4195 conftst2.$ac_objext.
4196 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4198 2005-10-24 Stepan Kasal <kasal@ucw.cz>
4200 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
4201 conftest.o, to see whether the compiler really obeys; rm the object
4202 file before and after the test and register it with ac_clean_files.
4203 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4205 2005-10-21 Stepan Kasal <kasal@ucw.cz>
4207 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
4208 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
4209 code so that the most common case requires less forks.
4211 2005-10-20 Stepan Kasal <kasal@ucw.cz>
4213 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
4214 not portable; thanks to Paul Eggert and Alexandre.
4216 * NEWS: Fix an old typo.
4218 2005-10-20 Jim Meyering <jim@meyering.net>

4221 the latter'', in two places.
4223 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
4225 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
4226 AC_LANG_PROGRAM, fixing a typo. Don't give details about
4227 the inner workings of AC_LANG_FUNC_LINK_TRY.
4228 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
4229 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4230 by the function rather than ignoring it.
4231 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4232 comparing its address. Intel's interprocedural optimization was
4233 outsmarting the old heuristic. Problem reported by
4234 Mikulas Patocka.
4236 2005-10-19 Stepan Kasal <kasal@ucw.cz>
4238 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
4240 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
4242 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

4245 2005-10-04 Stepan Kasal <kasal@ucw.cz>
4247 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
4248 before removing it (chmod -R u+rwx); there are three instances of this.
4250 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4251 Stepan Kasal <kasal@ucw.cz>
4253 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4254 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4255 make its content writable before removing it. Remove an errorneous
4256 comment from the end, where the logs of the failed tests are copied
4257 to the main log file.
4259 2005-09-27 Stepan Kasal <kasal@ucw.cz>
4261 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
4262 in case the computer is too quick. Double quote the configure.ac
4263 snippets.
4265 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
4266 problems if the testsuite were running too fast.
4268 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4270 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4271 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4272 (which belong to Xt, not X itself). See Debian bug 327655.
4273 * NEWS: Mention this.
4275 2005-09-07 Stepan Kasal <kasal@ucw.cz>
4277 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
4279 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
4281 * config/move-if-change: Don't output "$2 is unchanged";
4282 suggested by Ben Elliston. Handle weird characters correctly.
4284 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4286 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4287 calls, so that the final expansion of this macro is shorter.
4288 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4289 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4290 the cleanup there. Use AS_VAR_* macros, to be more general.
4291 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4293 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4295 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
4297 2005-09-01 Stepan Kasal <kasal@ucw.cz>
4299 * doc/autoconf.texi (Configuration Headers): Add an index entry
4300 for AH_HEADER.
4302 2005-08-26 Pavel Roskin <proski@gnu.org>
4304 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
4305 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
4306 running xmkmf.
4308 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4310 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4311 The previous patch didn't work, so try a better one.
4313 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4315 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4316 in the example. Reported by Bruno Haible.
4317 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4318 "if $undefined_var;" succeeds with my shell.
4320 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4321 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4322 but change the m4_divert_text to m4_divert_once.
4324 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4326 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4327 Work around bug in Solaris /usr/xpg4/bin/awk.
4328 The bug is present in at least Solaris 8 through 10.
4330 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4332 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4333 some evil values and relying on the fact that $* concatenates the
4334 parameters by the first character from IFS.
4336 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4337 Stepan Kasal <kasal@ucw.cz>
4339 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4340 first header appears, define AH_HEADER.
4341 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4342 Update limitations about when to call AC_CONFIG_HEADERS.
4343 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4344 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4345 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4346 ``Configuration Actions''; fix their index entries.
4348 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4349 options correctly. Process N-M as M-N if M is smaller than N.
4350 Process ranges correctly so that N-N will run only N.
4351 Sort and uniquify the tests that will be run. If there is more
4352 than one test, reinsert the banners for the tests.
4353 * tests/autotest.at (Keywords): Unmark XFAIL.
4355 2005-08-23 Stepan Kasal <kasal@ucw.cz>
4357 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4358 before passing the macro name to AH_TEMPLATE.
4360 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4361 now opens log after option processing; in particular, --version
4362 and --help do not touch config.log.
4364 * Makefile.maint: Revert the change from 2005-08-12.
4366 2005-08-22 Stepan Kasal <kasal@ucw.cz>
4368 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
4369 common code to...

4372 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4374 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4375 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4376 Language cleanup.
4378 * doc/autoconf.texi (Defining Symbols, Changed Results):
4379 Prepend to LIBS, not append, in examples.
4381 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4383 When building in place, set srcdir="."; suggested by Tim Van Holder.
4385 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4386 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4387 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4388 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4389 does not mean "no --srcdir option".
4391 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4393 * tests/autoscan.at (autoscan): New file.
4394 * tests/suite.at: Use it.
4395 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4396 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
4398 * tests/autotest.at (Keywords): Test keywords combinations.
4400 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4402 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4403 add "2>&1"; gzip 1.2.4 prints help on stderr.
4405 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4407 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4408 was pushdef'ed twice while popped only once. Push it only once.
4409 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4411 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4413 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
4414 prefixed by mere "===", not "configure: === ".
4416 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
4418 * Makefile.maint: Update from Bison.
4420 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4421 "<tab>" in comment, so that the point is understandable.
4423 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4425 Rewrite substantial part of lib/autoconf/status.m4.
4426 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4427 and CONFIG_COMMANDS are not processed in four separate loops.
4428 Instead, there is one main loop. This alows that the common code
4429 is expanded only once, thus config.status (and configure) is smaller.
4431 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4432 the AC_LIST_FILES and cousins macros are no longer used.
4434 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4435 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4436 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4437 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4438 contain the initialization, nor the for loop, nor the associated
4439 commands; all these go to ...
4440 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4441 _AC_OUTPUT_CONFIG_STATUS.
4442 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4443 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4444 (_AC_OUTPUT_FILE): The creation of the sed script ...
4445 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4446 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4447 _AC_OUTPUT_MAIN_LOOP.
4448 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4449 _AC_CONFIG_COMMANDS): Use ...
4450 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4451 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4452 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4453 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4454 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4455 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4456 ... new macros.
4457 (_AC_CONFIG_UNIQUE): Update.
4458 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4459 Replaced by this ...
4460 (_AC_LIST_TAGS): ... new common macro.
4461 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4462 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4463 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4464 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4465 this didn't belong to the `config commands' section.
4466 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4467 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4468 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4469 to the `config commands' section either.
4470 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4471 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4473 ... and many changes to the comments nearby.
4475 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4476 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4477 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4478 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4479 (#define header templates): The comment at the top of the generated
4480 header now includes the name(s) of the source file(s).
4482 Several unrelated small changes:
4484 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4485 parameter to AC_DIAGNOSE.
4486 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4487 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4488 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4489 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4490 with AU::AC_OUTPUT.
4491 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4492 in AC_OUTPUT doesn't double-quote it either.
4493 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4494 parameters.
4496 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4498 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4499 versions of Portland Group compiler produce single- and double-quoted
4500 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4501 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4503 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4505 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4506 This is a corrected version of yesterday's patch.
4508 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4510 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4511 path, too; insert a "===" to emphasize the line.
4513 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4514 ac_cv_build_alias to ac_build_alias.
4515 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4517 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4518 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4519 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4520 (AC_ARG_VAR): ... here.
4521 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4522 target_alias.
4524 Keep a list of all precious variables and process them with one simple
4525 for loop, instead of expanding all commands, or, OTOH, complicated
4526 processing of output of "set".
4527 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4528 variable names in new macro...
4529 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4530 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4531 a loop to assign all ac_env_* and ac_cv_env_* variables.
4532 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4533 to INIT_PREPARE.
4534 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4535 its value to shell variable ac_precious_vars and call
4536 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4537 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call

4561 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4563 Fix my changes from 2005-07-01; reported by Noah Misch.

4574 versions of autoconf.
4576 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4578 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

4583 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4584 sed substitution command, so that we allow | in program prefixes

4588 configure_input, top_builddir, srcdir, etc.
4589 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4590 PATH_SEPARATOR in AUTOTEST_PATH.
4592 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

4625 Likewise for --header; moreover, recognize --he and --h as shortcuts
4626 for --help in that case.
4628 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4629 matches the order of execution. No code changed.

4651 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4652 (AC_SUBST): Call it.
4653 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4654 the directory specific variables; but don't call it for configure_input.
4656 2005-06-28 Derek Price <derek@ximbiot.com>
4658 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4659 addition.
4661 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

4664 directory have inherent problems with special characters like spaces,
4665 due to limitations in Make syntax. Problem reported by Alexandre
4666 Duret-Lutz.
4667 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4683 because we really don't support spaces and suchlike in dir names.
4684 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4685 Don't worry about backslashes in srcdir; it can't happen now.

4712 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4713 b, t, r, w commands require single space, while : cannot have any.
4714 (Special Shell Variables): Fix sed code this in the example.
4715 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4716 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4718 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4719 expand to the empty list. Don't use two pairs of m4_changequote,
4720 it's not necessary.
4722 2005-06-20 Derek Price <derek@ximbiot.com>
4724 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

4728 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4729 * doc/autoconf.texi:
4730 Don't mention Solaris versions so much, if a
4731 problem is common to all extant versions of Solaris. Say "SunOS
4732 4" instead of "SunOS" for SunOS 4.
4733 (awk): Mention more of the limitations of traditional Awk.
4734 (cat): Don't talk about cat -v.
4736 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

4741 to be compatible with glibc strverscmp.
4742 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4744 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4745 on Mac OS X 10.4 reported by Peter O'Gorman in:

4747 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4748 Use shell builtins rather than 'expr', to work around expr bug.
4750 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4752 * doc/autoconf.texi: "filesystem" -> "file system".
4753 "behaviour" -> "behavior".

4756 as per POSIX.
4757 * lib/m4sugar/m4sh.m4: Likewise.
4758 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem

4761 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4762 (.x.1): Ignore the time stamp in the .TH line when deciding whether

4767 quotes and backslashes. Patch from Derek Price.

4772 AS_TR_SH.
4774 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4776 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4777 -u, since it outputs chatter if the input files are the same.
4778 Problem reported by Ralf Menzel.
4780 2005-06-08 Derek Price <derek@ximbiot.com>
4782 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4783 renaming them since they are about to be redefined anyhow.
4785 2005-06-08 Derek Price <derek@ximbiot.com>
4787 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4788 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4789 Move m4_undefine to alphabetical order.
4791 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4793 * README: Recommend GNU M4 1.4.3 or later.
4794 * doc/autoconf.texi (Introduction): Likewise.
4795 Reword to avoid some formatting glitches.
4796 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4797 Clarify explanation of HP compiler bug.
4798 Redo example output tp match current CVS snapshot.
4799 Use @example.org in email addresses when the examples
4800 might get inadvertently cut-and-pasted into user code.
4801 Remove example of autom4te usage that doesn't seem to work now.
4802 Use modern AC_INIT (except when the example is meant to be
4803 shown with Autoconf 2.13).
4804 Update ksh info for Solaris 9 and later.
4805 KB -> kB.
4806 Modernize description of Automake versions a bit.
4807 Don't claim a future version of Autoconf is near.
4808 * doc/install.texi: Reword to avoid some formatting glitches.
4810 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4813 follows its own advice about quoting better.
4814 Reword to avoid some formatting glitches.
4815 * doc/installt.exi: Reword to avoid some formatting glitches.
4817 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4818 Tru64 ksh pattern matching bug. Reported against Libtool by
4819 Albert Chin <libtool@mlists.thewrittenword.com> and
4820 Nicolas Joly <njoly@pasteur.fr>.
4822 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4824 m4_cdr of one-member list was [[]] (one-member list containing an
4825 empty string) instead of [] (an empty list. Callers were skewed to
4826 match this misbehaviour. As a consequence of this:
4827 - m4_foreach([x], [], [foo]) expanded to `foo', while
4828 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4829 This bug has been fixed:
4831 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4832 expand to an empty string; print error msg if called without
4833 an argument list.
4834 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4835 misbehaviour; handle [] and [[]] correctly.

4843 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4845 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4846 swallow records with more than 99 fields.
4847 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4848 parse the long line.
4850 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4852 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4853 swallow literals longer than 399. Reported by Ralf Wildenhues.

4859 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4860 to gfortran, and make these the first two compiler names
4861 checked (following the general autoconf preference for gcc).

4865 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4866 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4867 (testsuite): Make sure autotest.m4f is up-to-date before using it.

4871 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4872 expression of unbounded size when processing the --list
4873 option. This runs afoul of a limit of 399 bytes per regular
4874 expression on AIX. Problem reported by Ralf Wildenhues.

4883 Reword description of line replacement.
4885 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4887 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4888 now contain newlines, and substituted files must be referenced on
4889 a line alone; the sed scripts to substitute them are now very
4890 different.
4891 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4892 commands can be put in a sed script portably.
4893 * doc/autoconf.texi (Setting Output Variables): Document above
4894 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

4905 * tests/local.at: Don't attempt to check for negated character
4906 classes in shell scripts. The test was too brittle.
4908 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4910 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4911 * doc/autoconf.texi (Limitations of Builtins): Document this
4912 limitation.
4914 2005-05-24 Stepan Kasal <kasal@ucw.cz>

4924 messages when ac_unique_file is not found.
4925 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4926 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4927 commands, for consistency with AC_MSG_ERROR and such.

4942 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4943 (ac_top_builddir): ... this ...
4944 (ac_top_build_prefix): ... to this; the old name is also kept, for
4945 backward compatibility.
4946 (ac_top_builddir_sub): New variable, without the trailing slash,
4947 always nonempty.
4948 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

4962 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4963 argument to m4_foreach. I guess it was necessary in the past,
4964 but I think it's a no-op now.
4966 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4968 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4969 ``cat <<_ACEOF'' commands to one.
4970 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4971 * lib/autoconf/status.m4: On various places, use expr instead of
4972 ``echo|sed.''
4973 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4974 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

4976 a range.
4977 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4978 the wrong patterns between ``case'' and ``esac.'' The previous
4979 code had false positives.

5029 check.
5030 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
5031 enough arguments, similarly as in m4_bpatsubsts.

5040 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
5041 for absolute directory names in one loop.
5042 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
5043 abbreviations of --version and --debug.
5045 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
5047 * doc/autoconf.texi (Autoconf Language): Be more precise about
5048 quoting rules. Problems noted by Stepan Kasal.
5049 Also, throughout this document, be more careful about white space.
5050 "blank", "white space", and "space" all have different meanings
5051 and we should be careful to say what we mean.
5053 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
5055 Fix C++ related problems reported by Werner Lemberg.
5056 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
5057 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
5058 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
5059 avoid problems with C++ and throw.
5060 * tests/compile.at: .cpp, not .cc.
5062 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
5064 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5066 * doc/autoconf.texi (Generic Functions): Typos.
5068 2005-05-02 Gary V. Vaughan <gary@gnu.org>
5070 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
5071 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
5072 set by latest automake.
5074 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
5076 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
5077 outputs 0 on GNU/Linux these days.
5079 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
5081 * doc/autoconf.texi (Autoconf Language): Add more description
5082 about quoting heuristics.
5083 (Limitations of Builtins): Describe "set -" problems.
5085 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5087 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
5088 not newline.
5090 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5091 by AC_DEFINE; it was a mistake.
5092 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5094 2005-04-25 Stepan Kasal <kasal@ucw.cz>
5096 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
5098 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5100 * doc/autoconf.texi (External Software): Quadrigraphs are not
5101 processed correctly in AS_HELP_STRING; avoid this in the examples.
5102 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5103 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5104 comment and reduce m4_default([foo], []) to [foo].
5105 (m4_strip): Update the explanation.
5107 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5109 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5110 Remove core.conftest.* too; it's generated by Tru64 5.1.
5111 Problem reported by Jennis Pruett.
5112 * lib/autoconf/functions.m4
5113 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5114 Don't bother to remove core files; AC_RUN_IFELSE should do that
5115 for you.
5117 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5119 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
5121 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

5129 the comment.
5131 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
5133 * doc/autoconf.texi (External Software, Package Options): Add
5134 examples showing how to implement --with-* and --enable-* options.
5136 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
5138 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
5139 as well as configure.in. Problem reported by Gregorio Guidi.
5141 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
5143 * doc/autoconf.texi (Particular Functions): Use gnulib's current
5144 pattern for alloca snippet.
5146 2005-04-04 Stepan Kasal <kasal@ucw.cz>
5148 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

5152 * doc/autoconf.texi (Generic Programs): Fix a typo.
5154 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
5156 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
5157 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
5159 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5161 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5162 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5163 whole-archive (-zallextract, -zdefaultextract) options in the hope of
5164 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5165 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5167 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5169 * NEWS: The configure command now warns you if you attempt to use
5170 a directory whose name contains a special character like space,
5171 newline, or "\".
5172 * doc/autoconf.texi (Installation Directory Variables): Allow
5173 "," in file names. Do not use \@; it's not a portable regexp.
5174 * bin/Makefile.am (edit): Likewise.
5175 * lib/Makefile.am (edit): Likewise.
5176 * tests/Makefile.am (edit): Likewise.
5177 * tests/semantics.at: Likewise.
5178 * tests/torture.at: Likewise.
5179 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
5180 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
5181 * doc/autoconf.texi (File System Conventions): Warn about
5182 unportable file names.
5183 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5184 (AC_INIT): Use it.
5185 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5186 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5187 ac_pwd, and quote srcdir.
5188 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5190 * doc/autoconf.texi: Fix some systematic formatting problems.
5191 ".)" needs a following @: if not at the end of a sentence, and
5192 similarly for "!)". "etc." should be preceded by a comma.
5193 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5195 2005-03-22 Bruno Haible <bruno@clisp.org>
5197 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5198 argument is often called 'build-aux'.
5200 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5202 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5203 macro AC_TRY_LINK is obsolete.
5204 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5205 `AC_CONFIG_FILES'.
5207 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5209 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5210 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5211 from a Common Lisp's `cl'.
5212 (AC_PROG_CXX): Behave according to the documentation: don't
5213 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5214 make the variable CCC precious; use `cl.exe', not `cl'.
5216 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5217 Alexandre Duret-Lutz <adl@gnu.org>
5219 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5220 /dev/null, as "configure" shouldn't read stdin, and this insulates
5221 us from problems (e.g., when testing for "cl"). Also, do this
5222 redirection before invoking "hostname" or "uname", and keep the
5223 original input stream available via...
5224 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5225 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5226 bother with "</dev/null" since it's now done at the top of
5227 'configure'.
5228 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5229 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5230 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5231 * doc/autoconf.texi (File Descriptor Macros): New section.
5232 (Printing Messages): Mention it.
5233 * tests/base.at (Input/Output): New test.
5235 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5237 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5238 newline if neither \c nor -n work, as that would output two
5239 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5241 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5243 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5244 This causes that any required macros inside will get before the if.
5245 * doc/autoconf.texi (autom4te.cache): A typo.
5247 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5249 Undo previous change, except keep the change to
5250 lib/autoconf/programs.m4 that replaced grep with shell
5251 pattern-matching. This is because net-snmp configure reads stdin.
5252 Reported by Noah Misch.
5254 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5256 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5257 from /dev/null, as "configure" shouldn't read stdin, and this
5258 insulates us from problems (e.g., when testing for "cl").
5259 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5260 before invoking "hostname" or "uname".
5261 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5262 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5263 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5264 "</dev/null" since it's now done at the top of 'configure'.
5265 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5266 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5267 Also, replace grep with shell pattern-matching, to save a process.
5269 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5271 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5272 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5273 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5274 compiler.
5276 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5278 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5279 grep -q isn't portable. Improve grep -s explanation.
5280 Problem reported by Dan Manthey.
5282 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5284 * doc/autoconf.texi (Special Shell Variables): Clarify
5285 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5287 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5289 * doc/autoconf.texi: Use @acronym for DJGPP.
5290 Fix some @code's that should have been @env's, and vice versa.
5291 Sort environment variable names.
5292 Mention that shells no longer inherit IFS.
5293 Don't recommend PATH_SEPARATOR=';' so strongly.
5294 Mention that $RANDOM might expand to the empty string.
5295 "symlink" and "soft link" -> "symbolic link".
5296 Improve mktemp description (reported by Bruno Haible).
5298 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5300 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5301 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5302 Likewise.
5303 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5304 Likewise.
5306 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5308 * NEWS: Mention AT_COPYRIGHT.
5310 * tests/local.at (AT_CMP): Use diff directly on input files rather
5311 than copying them.
5313 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5314 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5316 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5317 and Paul Eggert <eggert@cs.ucla.edu>
5319 * tests/autotest.at (Empty test suite): New test.
5320 * tests/torture.at (Substitute and define special characters)
5321 (Substitute a 2000-byte string, Define to a 2000-byte string)
5322 (Substitute a newline, Define a newline): New tests.
5324 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5326 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5327 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5328 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5329 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5330 (Standard regular expressions): New test.
5331 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5332 excess test name quoting.
5333 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5334 CPPFLAGS to `configure' instead of setting it in `configure'.
5336 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5337 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5338 on some platforms.
5340 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5341 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
5343 * tests/local.at (AT_CMP): New macro.
5344 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
5345 (AC_SAVE_STATE): Move environment grep...
5346 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
5347 (AT_CONFIG_CMP): New macro.
5348 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
5349 * tests/c.at (Extensions): Do not exit early.
5350 * tests/atlocal.in: Inherit $GREP.
5352 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
5353 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
5355 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
5356 (AC_COPYRIGHT): Factor header comment portion out and move into...
5357 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
5358 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
5359 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
5360 --version output.
5361 * tests/local.at: Add Autoconf test suite copyright notice.
5362 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
5364 2005-02-04 Bruno Haible <bruno@clisp.org>
5365 and Paul Eggert <eggert@cs.ucla.edu>
5367 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
5369 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
5371 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5372 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5374 Try not to generated lines of unlimited length, as POSIX places a
5375 2047-byte limit on line length of portable text files.
5376 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5377 Use newline as a separator, not space.
5378 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
5379 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
5380 space.
5382 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5384 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
5385 as_func_*. Add test to check whether positional parameters
5386 are restored after function return.
5388 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
5390 * doc/autoconf.texi (Special Shell Variables): Mention _,
5391 BIN_SH, DUALCASE. Say that variables other than "status" are safe
5392 if they contain a lower-case letter. The DUALCASE problem was
5393 reported by Ralf Wildenhues.
5395 * bin/autoconf.as: Don't exit with status 0 after write failure
5396 with --help or --version.
5397 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
5398 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
5400 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5402 * doc/autoconf.texi (Limitations of Usual Tools):
5403 Unicos 9 sed limitations.
5404 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
5405 to get the option-enhanced interface on older Crays. Try ftn for
5406 Fortran 95 (newer Crays).
5408 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
5410 * man/Makefile.am (.x.1): Go back to the simple solution, but take
5411 care to echo the commands, so the user knows what's going on.
5412 Modified from a suggestion by Stepan Kasal.
5414 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
5415 with a cross reference. Derived from a suggestion by Bruce Korb.
5417 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
5419 * doc/autoconf.texi (config.status Invocation): Warn about
5420 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
5421 * doc/install.texi (Defining Variables): Likewise.
5422 Based on a proposed patch by Ralf Wildenhues.
5424 * man/Makefile.am (.x.1): Make sure the required generated files
5425 are up to date. Problem and original solution proposed by Stepan Kasal.
5426 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
5427 implicit-man-prerequisites): New rules, used by the above.
5429 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.

5435 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5436 Update the long comment explaining it.
5438 m4_require no longer writes an ``is required by'' line to the
5439 execution stack. It contains only one bit of non-redundant
5440 information: that the macro was required, not called. And even
5441 this bit is useless in most situations: have you ever met a macro
5442 which both calls and requires the same macro?
5444 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5445 (_m4_defun_pro_outer): ... only via this macro, for the outermost
5446 macro.
5447 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
5448 (m4_expansion_stack_pop): Remove the misplaced comment.
5449 (m4_require): Don't put the ``is required by'' line to the
5450 execution stack; slightly improve the out-of-a-defun error message.

5452 (_m4_require_call): Use it.
5453 * tests/m4sugar.at (m4_require): Expect output without the
5454 ``is required by'' messages.
5456 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5458 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5459 rather than x for expr.
5461 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5462 this is safe.
5463 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
5464 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

5477 support.
5478 * bin/autoheader.in: Pass $force to update_file so that
5479 config.h.in is always recreated when --force.

5490 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5492 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5493 Warn about newline stripping in `` and $(). Update Solaris
5494 version to 9.

5498 stripping.
5500 2005-01-19 Stepan Kasal <kasal@ucw.cz>

5522 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5524 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5548 otherwise.
5549 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5550 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5551 stored in _m4_divert_diversion or _m4_divert_dump.
5552 (m4_divert_pop): When the parameter is given, compare the symbolic
5553 name with the last diversion pushed on the stack. Previously, the
5554 current diversion was compared with the numeric value of the
5555 diversion given as the parameter.
5556 (m4_require): If the macro hasn't been expanded yet, call ...
5557 (_m4_require_call): this new macro.

5590 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

5643 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
5644 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

5771 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

5836 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>

5839 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5840 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
5841 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

5845 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

5857 out the common code to ...
5858 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
5859 value of the #define--default to 1, iff the macro was called
5860 with exactly one parameter.
5862 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5864 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5865 "char c = '\200';" rather than "char c = 0x80;" as the
5866 latter doesn't conform to the strict C standard due to
5867 overflow on signed char hosts.
5869 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5870 to -qlanglvl=ansi. We don't want to disable extensions.
5872 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
5874 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

5889 * doc/autoconf.texi (Libtool): Libtool can be used without
5890 Automake (not without Autoconf).
5891 (Introduction): Mention lists.gnu.org.
5892 * BUGS: Don't mention bugs.gnu.org.
5893 Remove mention of ancient libtool compatibility problem.
5894 * NEWS: Mention that bugs.gnu.org is kaput.
5895 * README: Likewise. Mention where mailing list archives can be found.
5897 2004-11-28 Stepan Kasal <kasal@ucw.cz>

5903 * doc/autoconf.texi (Pretty Help Strings): Go back to
5904 single-quoting assignments to cache variables.
5906 2004-11-23 Stepan Kasal <kasal@ucw.cz>
5908 * doc/autoconf.texi (Pretty Help Strings): Fix quoting issues

5925 (Pretty Help Strings): Likewise; remove the wrong comment;
5926 simplify the examples and improve their quoting.
5928 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5930 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5931 the $1_found variable, don't test whether the file is executable;
5932 Both things are checked ...
5933 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
5934 the former ``test -f''.
5935 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
5937 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
5939 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
5940 use cp -R instead.
5942 2004-11-10 Derek R. Price <derek@ximbiot.com>
5944 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
5945 limitations. Reorder paragraphs for clarity.
5947 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
5949 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
5950 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
5951 variants", "Unix", and some related minor wording fixups.
5953 (Shellology, Special Shell Variables): Document that the Zsh
5954 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

5966 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
5968 * doc/autoconf.texi (auindex): New macro.
5969 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
5970 Problem reported by Stepan Kasal.
5972 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5974 Fix problems reported by Andreas Buening in:
5975 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
5976 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5977 in test makefile.
5978 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
5979 readable; it's not true in OS/2-emx.
5981 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5983 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5984 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5985 (trivial change). Problem and patch reported by Andrew Church in:
5986 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5988 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5990 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
5991 three args in examples. Problem reported by Frederik Fouvry in:
5992 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
5993 Also, fix some minor spacing and punctuation bugs.
5995 2004-09-02 Akim Demaille <akim@epita.fr>
5997 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
5998 "case" to restore ordering.
5999 Reported by Stepan Kasal.
6001 2004-08-26 Akim Demaille <akim@epita.fr>
6003 * doc/autoconf.texi: Minor typos and stylos.

6009 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
6011 Version 2.59b.
6013 * README: Add advice about m4 1.4.2.
6015 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
6016 texinfo.tex for now (done by hand now).
6017 * Makefile.maint (wget_files, cvs_files):
6018 Remove ansi2knr.c; nobody uses it.
6019 (ansi2knr.c-url_prefix): Remove.
6020 (cvs-update): Fix test for failure. I don't know why it ever
6021 worked...
6023 * doc/autoconf.texi: Update URLs, some of which went stale.
6024 Use @uref rather than @href.
6026 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
6027 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
6029 * config/config.guess, config/config.sub, config/elisp-comp,
6030 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
6031 doc/fdl.texi, doc/standards.texi: Sync with master copy.
6033 * NEWS, TODO, configure.ac, bin/autoscan.in,
6034 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
6035 doc/install.texi, lib/Autom4te/Configure_ac.pm,

6039 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
6040 tests/tools.at, tests/torture.at:
6041 Use "file name" rather than "filename" or "path",
6042 to be consistent with the terminology of the GNU coding standards.
6044 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
6046 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
6047 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
6048 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
6049 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
6051 More fixes to support spaces in the name of the build directory.
6052 This isn't a complete fix but it's an improvement.
6054 * bin/autoconf.as (autom4te_options): New var.
6055 Use it instead of appending to AUTOM4TE, so that we can allow
6056 spaces in the build directory's absolute name.
6057 * bin/autoheader.in ($autoconf): Allow spaces in file names.
6058 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
6059 AT_CHECK_NOESCAPE): Likewise.
6060 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
6061 main program): Likewise.
6063 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
6065 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
6066 From Ralf Corsepius in:

6069 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
6071 * doc/autoconf.texi (Function Portability): Document isinf and
6072 and isnan. From a suggestion by Kevin Ryde.
6074 * lib/Autom4te/General.pm (END): Return correct exit status even
6075 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
6077 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
6079 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6080 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6081 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
6083 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6085 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
6086 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
6087 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
6088 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
6089 * lib/autom4te.in (Automake-preselections): Preselect
6090 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6092 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6094 * lib/autom4te.in (Automake-preselections): Preselect
6095 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6096 trace them.
6098 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6100 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6101 Tru64.
6102 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6103 Document problem with "`""`" in pdksh POSIX mode.
6105 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6107 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6108 with pdksh, too. Problem reported by Patrick Welche via
6109 Gary V. Vaughan.
6110 * doc/autoconf.texi (Shellology): Note that set -o posix is
6111 useful for pkdsh, too.
6113 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6115 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6116 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6117 Don't fail if ENV or BASH_ENV is readonly.
6118 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6119 etc. are read only. Problem reported by Ludovic Courtes.
6121 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6123 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6124 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6125 (trivial change)
6127 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6129 * doc/autoconf.texi (File System Conventions): Warn about
6130 names like "aux". Problem reported by Eric Blake.
6132 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6133 by zero instead of array size, so that we can use any arithmetic
6134 constant expression (instead of requiring an integer constant
6135 expression). This allows us to test expressions like DBL_MAX <
6136 LDBL_MAX, which didn't conform to the C standard using the old
6137 method.
6138 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6139 now that we can do floating-point tests at compile time.
6141 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6143 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6144 and LDBL_EPSILON, as the resulting expression isn't an
6145 integer constant expression and violates the C standard.
6146 Problem reported by Nelson H. F. Beebe. Also, check
6147 for "L" suffix, and check that long double doesn't have
6148 worse range or precision than double, that mixed-mode
6149 arithmetic doesn't generate a diagnostic, that double
6150 constants fit in long double.
6152 2004-06-03 Kevin Ryde <user42@zip.com.au>
6154 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6155 malloc(0) and realloc(NULL,size).
6157 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6158 Bob Proulx.
6160 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6162 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6163 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6164 by Jim Meyering.
6166 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6168 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6169 can be rewritten using if-then-else. Suggested by Bruno Haible.
6171 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6173 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6174 Problem reported by Stepan Kasal.
6176 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6178 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6179 change). Patch reported by Ralf Wildenhues in
6180 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6182 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6183 function F exists if the compiler and linker let you compile an
6184 expression like (F != 0). Recent versions of GCC optimize away
6185 the reference to F in that case, since every function address must
6186 be nonzero, so the link succeeds even if F does not exist.
6187 Problem reported by Manu in
6188 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6190 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6191 "Unix". Many uses changed.
6192 (Limitations of Builtins): Explain better why the ! command isn't
6193 portable.
6195 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6197 * lib/autom4te.in (Automake-preselections): Preselect
6198 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6200 2004-05-19 Kevin Ryde <user42@zip.com.au>
6202 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6203 referencing AC_FUNC_STRERROR_R.
6205 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6206 note pessimistic assumption when cross compiling.
6208 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6210 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6211 (until 2004) invoked subcommands with sh -e, contra POSIX.
6212 Reported by Kevin Ryde.
6214 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6216 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6217 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6218 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6219 `test -f " /usr/bin/grep"', which _always_ failed.
6220 (AC_PROG_SED): Ditto bogus PATH fix.
6221 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6222 requires that grep correctly supports _multiple_ `-e' options, rather
6223 than stating only that grep should accept `-e'.
6225 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6227 Port to C99, which requires that 'exit' be declared.
6229 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6230 to ensure that stdlib.h is included.
6231 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6232 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6233 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6234 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6235 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6236 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6237 when using 'exit' in a test; C99 requires that 'exit' be declared.
6239 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6241 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6242 now prefers 'grep' implementations that accept -e.
6243 (Limitations of Usual Tools): Describe problems of traditional
6244 egrep and fgrep with long input lines, and of traditional grep
6245 with -e.
6246 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6247 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6248 All callers changed. Append /usr/xpg4/bin to the PATH, for
6249 Solaris.
6250 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6251 the user with complaints about multiple -e options.
6252 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6253 Define it with AC_PROG_GREP.
6254 * configure.ac (AC_PROG_GREP): Add.
6255 * lib/freeze.mk (GREP): New macro.
6257 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6259 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6260 a possible candidate only after all others fail, rather than
6261 consulting it first. This improves backward compatibility by
6262 better reflecting the way shell selection occurred in previous
6263 versions of Autoconf, and should help to avoid triggering latent
6264 problems in other packages, such as the one in Automake where zsh
6265 is not handled robustly:
6266 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6267 Although it is not Autoconf's responsibility to work around
6268 problems in Automake, it nevertheless makes sense to avoid
6269 introducing unnecessary incompatibilites.
6271 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6272 Gary V. Vaughan <gary@gnu.org>
6274 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6275 how deeply nested we are when a suitable tool is found, set the
6276 ac_path_TOOL_found flag.
6277 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6278 nested we are in this macro. Break out of all 3 nested loops if
6279 ac_path_TOOL_found is set.
6281 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6283 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6284 of the _AS_PATH_WALK loop too if GNU flavor is found.
6286 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6288 * doc/autoconf.texi (Limitations of Make): Update documentation
6289 for `$<'. New entry `Long lines', based on a report from Simon
6290 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6291 paragraph about DJGPP, based on a mail from Richard Dawe.
6293 2004-04-20 Paul Eggert <eggert@twinsun.com>
6295 * tests/c.at (C keywords): Don't assume that GCC supports
6296 "restrict" and "inline", as sufficiently-old GCC versions do not
6297 (also, GCC configured to be in pedantic C89 mode does not).
6298 Problem reported by Sumit Pandya in:
6299 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6301 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6302 consider -g to work if it generates warnings when plain compiles
6303 don't. Problem reported by Braden McDaniel in:
6304 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6306 * doc/autoconf.texi (Slashes): New section, to document a problem
6307 reported by Jim Meyering in:
6308 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6310 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6311 linker output files before linking, to work around IRIX 6 linker bug.
6312 Problem reported by Rainer Orth in:
6313 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6315 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6317 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6318 best tool so far counter rely on the tool path variable name to
6319 avoid checks for one tool being affected by the results of running
6320 the length check on a previous tool.
6322 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6323 match expression argument, as different greps have different
6324 regular expression flavours.
6325 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6326 literals.
6327 (AC_PROG_EGREP): Pass 'EGREP$'.
6328 (AC_PROG_GREP): Pass 'GREP$'.
6330 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6332 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6333 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6335 2004-03-29 Paul Eggert <eggert@twinsun.com>
6337 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6338 Types, Specific Compiler Characteristics, System Services,
6339 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6340 etc. consistently instead of 'long', 'short', 'unsigned' etc.

6357 HAVE_STRUCT_TM_TM_ZONE is not defined.
6358 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6359 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

6417 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6418 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than

6445 2004-02-18 Paul Eggert <eggert@twinsun.com>
6447 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6448 problem on QNX reported by Stephen Rasku in
6449 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6451 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

6460 AC_SUBST provides no portable way to escape literal newlines.
6462 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6463 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6464 Darwin uses -lcrt2.o and there's little point to cataloging all
6465 the system variants. Partial fix reported by Andreas Waechter in:
6466 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

6497 (_AS_SHELL_FN_SPY): New macro.
6498 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

6510 use AS_INIT_WITH_SHELL_FN.
6511 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6513 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

6541 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6542 2003 (except 1997) to the list of copyright years. This undoes
6543 the 2003-05-22 change, which removed the older years from the list.
6544 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6546 2004-01-27 Gary V. Vaughan <gary@gnu.org>

6586 sources.
6588 2004-01-26 Paul Eggert <eggert@twinsun.com>
6590 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6591 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6592 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6593 not <inttypes.h>. Problem reported by Tim Mooney in
6594 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6595 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6596 Likewise.
6598 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6599 otherwise "make check" fails because it forbids cmp (I guess
6600 because cmp treats files as binary on DOS-like systems).
6602 * tests/mktests.sh: Update copyright date to 2004, since some tests
6603 have changed in 2004.
6605 2004-01-23 Gary V. Vaughan <gary@gnu.org>

6608 non-truncating sed or gsed program in PATH.
6609 * tests/acprograms.at: Add it.

6611 * NEWS: Updated.
6613 2004-01-15 Paul Eggert <eggert@twinsun.com>
6615 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6616 -std1 disables some useful extensions on Tru64. Problem reported
6617 by N. Lichtmaier in
6618 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6620 2004-01-14 Paul Eggert <eggert@twinsun.com>
6622 * doc/autoconf.texi (Programming in M4sh): Document that
6623 AS_MKDIR_P succeeds if the destination is a symbolic link
6624 to an existing directory.
6625 (Limitations of Usual Tools): Note that mkdir -p might not
6626 succeed on symlinks to directories.
6628 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6630 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6631 * bin/autoheader.in: Grammar fix in message.
6632 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6633 Test for dir before calling mkdir -p. (trivial changes)
6635 2004-01-13 Eric Blake <ebb9@byu.net>
6637 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6638 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6640 2004-01-10 Jim Meyering <jim@meyering.net>
6642 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6644 2004-01-09 Paul Eggert <eggert@twinsun.com>
6646 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6647 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6648 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6649 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6650 AC_COMPILE_IFELSE, since we now assume our caller invokes
6651 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6652 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6653 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6654 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6656 2004-01-07 Paul Eggert <eggert@twinsun.com>
6658 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6659 `"'...'"`, as it's confusing (and I suspect it may not work on
6660 some platforms). The code was incorrect anyway, as it assumed
6661 that \$ evaluated to itself in that context. Reported by
6662 Alexandre Duret-Lutz.
6664 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6666 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

6671 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6672 example, and add more examples. Reported by Eric Sunshine.
6674 2004-01-05 Paul Eggert <eggert@twinsun.com>
6676 * doc/autoconf.texi (Limitations of Usual Tools):
6677 Remove warning against "rm -fr" introduced yesterday; it
6678 was a false alarm.
6680 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6681 autoscan, autoupdate, ifnames): Don't use chmod -w.
6682 * lib/Makefile.am (autom4te.cfg): Likewise.
6683 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6684 "chmod -w".

6692 2004-01-04 Paul Eggert <eggert@twinsun.com>
6694 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6695 Use "rm -f" to remove conftest.sed, not plain "rm".
6696 Bug reported by David Relson in
6697 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6699 * Makefile.am (autom4te-update):
6700 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6701 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6702 * doc/autoconf.texi (Guidelines): Likewise.

6712 Warn against "rm -fr".
6714 2004-01-03 Paul Eggert <eggert@twinsun.com>
6716 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6717 -c -o might not work. From a suggestion by Kevin Ryde.
6718 (C Compiler, Generating Sources, Limitations
6719 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6720 Don't put '-o' after non-options, as POSIX doesn't allow this.
6721 Mention that cc's name might be gcc or c89 or whatever.
6723 2004-01-04 Kevin Ryde <user42@zip.com.au>
6725 * doc/autoconf.texi: Add various further index entries.
6727 2003-12-29 Paul Eggert <eggert@twinsun.com>
6729 * bin/autoreconf.in (autoreconf_current_directory):
6730 Fix typo: mkdir without umask arg.
6732 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6734 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6735 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6736 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6737 explanation clearer.
6739 2003-12-24 Andreas Schwab <schwab@suse.de>
6741 * doc/autoconf.texi (Default Includes): Fix misspelling of
6742 AC_INCLUDES_DEFAULT.

6746 * configure.ac: Test if sh -n works.
6747 * configure: Regenerate.
6748 * tests/atlocal.in: Store the result here.
6749 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6750 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6751 of explicitly testing.
6752 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6753 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6754 * tests/tools.at (Syntax of the shell scripts): Simplify
6755 using AT_CHECK_SHELL_SYNTAX.
6756 (Syntax of the Perl scripts): Remove definition of
6757 AT_CHECK_PERL_SYNTAX.
6759 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6761 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
6762 stderr to /dev/null.

6769 Extracted from AS_SHELL_SANITIZE.
6770 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6771 macros.
6772 (AS_SHELL_SANITIZE): Move reinvocation code from
6773 _AS_LINENO_WORKS, use it to find out if shell
6774 functions work.
6775 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6776 does not work.
6777 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

6788 * config/announce-gen (&print_locations, &print_signatures)
6789 (&sizes): New.
6790 Use them.

6792 them on the fly.
6794 2003-11-24 Akim Demaille <akim@epita.fr>
6796 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

7000 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
7001 cross test.
7003 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
7005 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
7006 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

7018 Problems reported by Eric Sunshine.
7020 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7022 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7023 -mGLOB_options_string stuff for Intel ifc, which can cause

7047 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7048 cache variable instead of $G77 to decide whether to include -O2,
7049 since $G77 is specific to Fortran 77.

7053 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

7058 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7059 arguments so that it can be used with syntax identical to
7060 AC_PROG_F77, and so that we can more easily decide to
7061 remove/deprecate the DIALECT optional argument in the future if it
7062 proves troublesome.
7063 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7064 non-freeform-supporting compilers. Document freeform flags.
7066 2003-10-03 Akim Demaille <akim@epita.fr>
7068 * configure.ac: Look for emacs, not macs.

7078 2003-10-03 Akim Demaille <akim@epita.fr>
7080 * configure.ac: Quotation and formatting changes.

7115 have been created when invoking the compiler.

7130 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7131 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7133 2003-09-26 Akim Demaille <akim@epita.fr>
7135 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7136 directory for AC_CONFIG_COMMANDS' first argument exists.
7137 This makes valid the invocation of _AC_SRCPATH that follows.
7138 Reported by Eric Sunshine.
7139 * doc/autoconf.texi (Configuration Commands): Adjust.
7141 2003-09-26 Akim Demaille <akim@epita.fr>
7143 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7144 Reported by Ralf Corsepius.

7148 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
7149 arguments.

7160 2003-09-26 Akim Demaille <akim@epita.fr>
7162 The test suite are sometimes assigning timings incorrectly.
7163 Reported by Henk Krus.
7164 Diagnosed by Nicolas Joly.
7166 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7167 AT_help_all.
7168 Instead of making AT_help a sequence of assignments to grow
7169 $at_help_all, just make AT_help_all be the growing contents of
7170 $at_help_all, and make a single assignment in...
7171 (AT_INIT): here.
7172 (at_times_skip): Flip the meaning and rename as...
7173 (at_times_p): this.
7174 (AT_INIT): When summarizing the test that ran, remove
7175 $at_times_file after use, and check it is present before trying to
7176 use it.

7184 (ifnames): chmod -w.
7185 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7186 executables, not bin/ executables! Otherwise all the magic needed
7187 to find non installed files is turned off. This caused a failure
7188 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7189 as found in its environment (sent by tests/autoreconf): pointing
7190 to bin/autom4te that could not find its files.
7191 * tests/mktests.sh: Force the replacement of generated files, for
7192 the sake of "mv" program that are interactive when overwriting a
7193 -w file.

7204 Trivial change to support GCC's configuration procedure.
7205 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
7206 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
7207 about inconsistency if the preprocessor is set to give errors for
7208 any warning.

7227 2003-09-12 Akim Demaille <akim@epita.fr>
7229 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
7230 not asm/types.h.
7232 2003-09-11 Akim Demaille <akim@epita.fr>
7234 * doc/autoconf.texi (Header Portability): linux/random.h.
7235 From Peter Hendrickson.
7237 2003-09-10 Akim Demaille <akim@epita.fr>
7239 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
7240 willing to edit the output files.
7242 2003-09-10 Akim Demaille <akim@epita.fr>
7244 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
7245 and AC_FC_FREEFORM.
7246 * tests/mktests.sh: Skip AC_FC_SRCEXT.
7247 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

7263 Improve the accuracy of the wording about obsolescence.
7264 From a suggestion by Ian Lance Taylor in
7265 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
7267 2003-09-05 Paul Eggert <eggert@twinsun.com>
7269 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
7270 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
7272 2003-09-04 Akim Demaille <akim@epita.fr>
7274 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
7275 AC_FUNC_WAIT3.
7277 2003-09-04 Akim Demaille <akim@epita.fr>
7279 * bin/autom4te.in: Use &fatal where more appropriate than &error.
7280 (freeze): When exiting, use $exit_code.
7281 * lib/autoconf/fortran.m4: Comment changes.
7283 2003-09-04 Akim Demaille <akim@epita.fr>
7285 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7287 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7289 Add support for newer Fortran dialects. The F77 interface is
7290 unchanged, and continues to support Fortran 77. New FC macros
7291 correspond to all the old F77 macros, with output variables FC,
7292 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7293 available dialect, but older dialects can be specified. There are
7294 new macros AC_FC_SRCEXT to set the source extension, and
7295 AC_FC_FREEFORM to accept free-form source files.
7297 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
7298 New macros.
7299 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
7300 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
7301 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
7302 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

7310 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
7311 AC_FC_SRCEXT, AC_FC_FREEFORM):
7312 New macros.
7313 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
7314 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
7315 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
7316 Rewrite in terms of the above.
7317 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
7318 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

7320 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
7322 2003-09-02 Paul Eggert <eggert@twinsun.com>
7324 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
7325 Document problems with timestamp resolution that 'make', 'cp -p', and
7326 'touch -r' have.
7328 2003-08-27 Akim Demaille <akim@epita.fr>
7330 * tests/m4sugar.at (cross_warning): Make sure to enable the
7331 output, so that we can track spurious m4sugar output.
7332 * tests/local.at: Require 2.57.
7333 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7334 are defaulted by AT_CHECK anyway.
7335 Use AT_CHECK_AUTOM4TE.
7336 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7337 missing dnl.
7339 2003-08-27 Akim Demaille <akim@epita.fr>
7341 * bin/autoheader.in: Issue the "Using auxiliary..." message only
7342 when -Wobsolete is set.
7343 Set it on by default.
7344 Suggested by Klee Dienes.
7346 2003-08-27 Akim Demaille <akim@epita.fr>
7348 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
7349 documentation.

7355 after AC_OUTPUT.
7357 2003-08-25 Akim Demaille <akim@epita.fr>
7359 * config/announce-gen, GNUmakefile, Makefile.maint: Update from

7381 * Makefile.maint (local-check): Rename as...
7382 (local-checks-available): this.
7383 (local-check): New.
7385 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
7386 * configure.ac: Require Automake 1.7.6.
7388 2003-08-22 Akim Demaille <akim@epita.fr>
7390 Output stack traces in warnings.
7392 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
7393 Replace the former...
7394 (m4_warn): Pass the call stack to _m4_warn.
7395 * bin/autom4te.in: Adjust to output the call stack.
7396 * tests/m4sugar.at (m4@&t@_warn): Adjust.
7398 2003-08-22 Akim Demaille <akim@epita.fr>
7400 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
7401 * bin/autom4te.in: Adjust.
7403 2003-08-21 Akim Demaille <akim@epita.fr>
7405 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7406 (&verbose): Remove.
7407 (&getopt): Adjust the note and verb channels, depending upon
7408 --verbose.
7409 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
7410 * bin/autoupdate.in: Adjust.
7411 Use &verb, not &verbose.
7413 2003-08-21 Akim Demaille <akim@epita.fr>
7415 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7416 &parse_WARNINGS.
7417 ($help): Use Autom4te::ChannelDefs::usage.
7418 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7419 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7421 2003-08-21 Akim Demaille <akim@epita.fr>
7423 First stab at preserving warnings between calls to autom4te,
7424 including when the cache is used.
7426 There are still several issues: (i) there are too many runs of m4
7427 (one for include, one for warnings, and some more), (ii) warnings
7428 spreading on several lines are not handled gracefully, (iii) the
7429 code meant to have the call stack display for errors does not work
7430 (its handling should move from m4 to autom4te).
7432 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7433 Use them.
7434 (@preselect): Add m4_warn.
7435 ($exit_status): Remove, use $exit_code.
7436 ($help): Use Autom4te::ChannelDefs::usage.
7437 (&handle_m4): No longer define the m4_warnings.
7438 At each run, extract and report the warnings.
7439 Always cache the result, including if the exit status is on
7440 failure, since if nothing changes, we should result in the same
7441 failure, hence we can use the cache.
7442 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7443 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7444 Remove.
7445 (m4_warn): Redefine as a do-nothing: it is its invocation that
7446 matters, as warnings are now reported via traces.
7447 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7448 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7449 the latter reveals calls to the former.
7451 Adjust the tests.
7453 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7455 2003-08-21 Akim Demaille <akim@epita.fr>
7457 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7458 Use them.
7460 2003-08-21 Akim Demaille <akim@epita.fr>
7462 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7463 forward order.
7464 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7465 (&parse_warnings): Accept a list of warning requests.
7466 (&usage): Return a string, not a side effect.
7467 (cross): New warning category.
7469 2003-08-21 Akim Demaille <akim@epita.fr>
7471 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7472 (&require_configure_ac): Accept an optional directory argument.
7473 ($configure_ac): Remove.
7474 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7475 (&catfile): Remove.
7476 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7477 * bin/autoscan.in: Adjust.
7479 2003-08-20 Akim Demaille <akim@epita.fr>
7481 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7482 Reported by Alexandre Duret-Lutz.
7484 2003-08-20 Akim Demaille <akim@epita.fr>
7486 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7487 * bin/autom4te: Adjust.
7488 In particular, be Autoconf tools are really silent when properly
7489 working, bind the verbosity of the 'note' channel to $verbose.
7490 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7491 (&xsystem, &contents): Remove, since they are exported by...
7492 * lib/Autom4te/FileUtils.pm: this.
7493 More perldoc.
7494 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7495 * lib/Autom4te/FileUtils.pm: here.
7497 2003-08-20 Akim Demaille <akim@epita.fr>
7499 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7500 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
7501 from CVS Automake.
7503 2003-08-20 Akim Demaille <akim@epita.fr>
7505 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
7506 (autom4te-update): New.
7507 * Makefile.cfg (update): Bind autom4te-update.

7511 * lib/autotest/general.m4: Comment various HELP_* diversions.
7512 (PARSE_ARGS_BEGIN): New section for option parsing related

7523 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7525 * lib/autom4te.in (Automake-preselections): Preselect
7526 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
7527 and m4_sinclude.
7529 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7531 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
7532 (Autoconf-without-aclocal-m4): ... this new language.
7533 * doc/autoconf.texi (autom4te Invocation): Mention
7534 Autoconf-without-aclocal-m4.

7539 RUN-IF-PASS optional arguments.

7550 2003-08-14 Derek Price <derek@ximbiot.com>
7552 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7553 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7554 shorter column three. Add DESCRIPTION to log file content.
7556 2003-08-13 Derek Price <derek@ximbiot.com>
7558 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7559 output.
7561 2003-08-12 Derek Price <derek@ximbiot.com>
7563 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7564 (AT_CHECK_NOESCAPE): Move core functionality to...
7565 (_AT_CHECK): ...this new macro.
7567 2003-08-07 Derek Price <derek@ximbiot.com>
7569 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7570 (AT_CHECK_NOESCAPE): ...to this new macro.
7572 2003-07-31 Paul Eggert <eggert@twinsun.com>
7574 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7575 in Bash 2.01. Problem reported by Brian Gough in
7576 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7578 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7580 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7581 -lcrt1.o, for OS X. (trivial change)
7583 2003-07-07 Paul Eggert <eggert@twinsun.com>
7585 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7586 inside '#ifndef __cplusplus'. Problem reported by
7587 Bob Friesenhahn.
7589 2003-07-06 Bill Clarke <llib@computer.org>
7591 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7592 'long', not 'int', for benefit of Sun's recent C++ compilers
7593 (trivial change). See:
7594 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7595 (This really should be 'intptr_t', not 'long', but that would
7596 take more work.)
7598 2003-06-25 Akim Demaille <akim@epita.fr>
7600 * lib/Makefile.am (autom4te.cfg): Make it read only.
7601 Depend on Makefile since it contains substitutions.
7602 From Paolo Bonzini.
7603 * lib/autom4te.in (args): Add local.at? for Autotest args.
7604 This change was made on autom4te.cfg which is generated.
7605 Reported by Raja R. Harinath.
7607 2003-06-25 Akim Demaille <akim@epita.fr>
7609 * doc/autoconf.texi (Header Portability): sys/mount.h.
7610 From Gareth McCaughan.
7612 2003-06-23 Akim Demaille <akim@epita.fr>
7614 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7615 not all of them. This fixes 1. the fact that when testing
7616 Autoconf there are many many config.log, 2. the incorrect use of
7617 top_srcdir to find config.log.
7618 Don't mix the detailed output of failed test with the summary of
7619 failures. Rather, append detailed log afterwards.
7621 2003-06-23 Akim Demaille <akim@epita.fr>
7623 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7624 always run: output config.log on $at_group_log.
7626 2003-06-23 Akim Demaille <akim@epita.fr>
7628 * tests/torture.at (#define header templates): Don't use quotes in
7629 C++ comments as it puzzles Emacs' sh font-lock-mode.
7631 2003-06-23 Akim Demaille <akim@epita.fr>
7633 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7634 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7635 * tests/atspecific.m4: Rename as...

7637 * tests/suite.at: Move the globals into...
7638 * tests/local.at: here.
7639 * tests/Makefile.am: Adjust.
7640 * doc/autoconf.texi (testsuite Scripts): Adjust.
7642 2003-06-21 Kevin Ryde <user42@zip.com.au>
7644 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7645 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7646 ensuring we add -std1 for full-ANSI.
7648 * doc/autoconf.texi (hdrindex): New macro.
7649 Add index entries for portability of various standard header files.
7651 2003-06-20 Akim Demaille <akim@epita.fr>
7653 * configure.ac: Bump to 2.57b.
7655 2003-06-20 Akim Demaille <akim@epita.fr>
7657 Version 2.57a.
7659 2003-06-20 Akim Demaille <akim@epita.fr>
7661 * bin/autom4te.in: Don't rely on $HOME being defined.
7662 Reported by Marc Espie as PR/233.
7664 2003-06-20 Akim Demaille <akim@epita.fr>
7666 * lib/autotest/general.m4: Use at_times_file only if used.
7667 From Nicolas Joly.
7669 2003-06-20 Akim Demaille <akim@epita.fr>
7671 * config/config.guess, config/config.sub, config/elisp-comp,
7672 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7673 Update from masters.
7675 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7677 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7678 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7679 (TEST_SCRIPT): New diversion.
7680 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7681 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7682 (AT_INIT): Support for expected failures.
7684 2003-06-02 Akim Demaille <akim@epita.fr>
7686 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7687 changes.
7688 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7689 Autoconf nor Automake.
7690 (&contents): New, from Automake.
7691 PODify.
7693 2003-05-28 Paul Eggert <eggert@twinsun.com>
7695 * NEWS, doc/autoconf.texi (Particular Functions),
7696 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7697 is the inverse of localtime.
7699 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7701 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7702 (handle_exec_errors): New function. Work around $! being
7703 altered by WEXITSTATUS.
7704 (xqx, xsystem): Use handle_exec_errors.
7706 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7708 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7709 Do not call `_exit()', simply modify `$?'.
7710 (xsystem): Reset $! before running system, and check it afterward.
7711 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7712 63 for version mismatches.
7714 2003-05-23 Akim Demaille <akim@epita.fr>
7716 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7717 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7718 the middle of a line).
7719 * lib/m4sugar/m4sugar.m4: Likewise.
7720 Remove useless spaces in comments.
7722 2003-05-23 Akim Demaille <akim@epita.fr>
7724 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7725 exit 63, so that we (or Automake's "missing") can tell the
7726 difference with a plain failure.
7727 * doc/autoconf.texi (Notices): Adjust.
7729 2003-05-23 Akim Demaille <akim@epita.fr>
7731 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7732 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7733 White spaces cleanup.
7735 2003-05-22 Jim Meyering <jim@meyering.net>
7736 Paul Eggert <eggert@twinsun.com>
7738 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7739 Remove `#include <stdlib.h>' from the list; we should never
7740 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7741 resulting namespace pollution would cause other tests to fail.
7742 Configure scripts run with some older versions of g++ and HP's
7743 aCC would fail due to such an #include. Problems reported by
7744 Matthew Mueller in <http://bugs.debian.org/120704> and by
7745 Keith Bostic in
7746 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7747 In the test, use the test declaration before including <stdlib.h>,
7748 as that's closer to how it'll be used.
7750 2003-05-23 Akim Demaille <akim@epita.fr>
7752 * doc/autoconf.texi (Header Portability): ucred.h.
7753 From Ian Redfern.
7755 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7757 Overhaul Autotest's logging: generate separate log files
7758 in testsuite.dir/NNN/testsuite.log, and append them to
7759 testsuite.log instead of re-running the test verbosely.
7761 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7762 file descriptor, write 0 to at_status_file instead of setting
7763 at_status=0, initialize some new variables (at_status_file,
7764 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7765 to rerun the tests, instead append the at_group_log to the
7766 at_suite_log when a test fails.
7767 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7768 with the AS_MESSAGE_LOG_FD redirected to stdout.
7769 (AT_CLEANUP): save the output status in $at_status_file
7770 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7771 its original place.
7772 (AT_CHECK): since tests are run with a redirected stdout,
7773 and used to be re-run in verbose mode, turn some $at_verbose
7774 into echo, and don't redirect the output of testing stdout
7775 and stderr.
7777 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7778 the name of the debugging directory and information about
7779 its contents.
7781 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7783 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd

7896 and truncate.
7898 2003-05-06 Akim Demaille <akim@epita.fr>
7900 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7901 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7902 by aclocal.m4 is changed it might require the importing of another
7903 m4 extension file, i.e., aclocal must be run.
7905 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7906 (&parse_args): Use --force with aclocal if required and supported.

7914 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7915 argument instead of a file name, so that the request file remains
7916 open during the whole autom4te run.
7917 ($icache_file): New.
7918 (&freeze): Lock the $icache_file.
7920 2003-04-29 Derek Price <derek@ximbiot.com>
7922 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7923 seperator with m4_append_uniq(). It doesn't work.
7924 (AT_CLEANUP): Add `;' to end of at_help_all.
7925 (AT_INIT): Allow --keywords to be specified more than once. When
7926 grepping $at_help_all for keywords, use the field and keyword
7927 seperators to ensure a complete keyword match. Alter at_prev handling
7928 to support the new --keywords behavior.
7930 2003-04-27 Karl Berry <karl@freefriends.org>
7932 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7933 align better with others. I also made some of the individual
7934 entries on one line, for brevity and to make it easier for me to
7935 sort my dir-example file in the Texinfo distribution :).

8155 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8156 innocuous variant befor including <limits.h> or <assert.h>. This
8157 works around a bug reported by Albert Chin: HP-UX 11i
8158 (and earlier versions) have a <limits.h> that declares
8159 gettimeofday and many other functions.
8161 2002-12-03 Paul Eggert <eggert@twinsun.com>

8172 Martin Frydl in
8173 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8175 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8176 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8177 defined, to support freestanding compilers. This should fix the
8178 bug reported by Momchil Velkov in
8179 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8181 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8182 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

8187 * Makefile.maint (www-gnu): New macro.
8188 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
8189 the location has moved.
8191 2002-12-02 Martin Frydl <martin@systinet.com>
8193 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
8194 \(.*\) match is too long and there is something more to be checked.
8195 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

8215 2002-11-14 Akim Demaille <akim@epita.fr>
8217 * Makefile.maint: Sync with Bison, i.e.:
8218 (po-check): Scan .l and .y files instead of the
8219 .c and the .h files that they generate. This fixes the bug
8220 reported by Tim Van Holder in:
8221 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8222 Look for N_ as well as for _. Try to avoid matching #define for
8223 N_ and _.
8224 From Paul Eggert.

8250 config.status -q option.
8252 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

8277 Reported by Ezra Peisach.
8279 2002-11-05 Akim Demaille <akim@epita.fr>
8281 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8282 Remove.
8283 We _have_ to stop using the old compatibility scheme that tried to
8284 avoid useless backslashes because Libtool 1.4.3 contains a
8285 AC_DEFINE([error_t], [int],
8286 [Define to a type to use for \`error_t' if it is not
8287 otherwise available.])
8288 We _have_ to quote the single quote and backslashes with \. The
8289 old compatibility scheme saw that ` was backslashed, and therefore
8290 did not quote the single quote. Hence before this patch, Autoconf
8291 was not compatible with Libtool.
8293 2002-11-04 Paul Eggert <eggert@twinsun.com>

8365 Problem reported by Bruno Haible.
8367 2002-10-29 Akim Demaille <akim@epita.fr>

8681 longer required can still cause errors.
8682 Reported by Alexandre Duret-Lutz.
8684 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

8734 * tests/torture.at (AC_ARG_VAR): Have configure report the value
8735 of `precious'.
8737 2002-10-11 Akim Demaille <akim@epita.fr>
8739 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
8740 file name to enable parallel executions.
8741 From Sam Varshavchik.
8743 2002-10-08 Akim Demaille <akim@epita.fr>
8745 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8746 aclocal invocation, as Gettext macros might not be visible to
8747 aclocal.
8748 Instead of blindly running autopoint, scan configure.ac (not the
8749 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8750 Reported by Paul D. Smith.
8752 2002-10-08 Paul Eggert <eggert@twinsun.com>
8754 Work around problems found when POSIXLY_CORRECT=1 is set.
8755 None of this seems to have anything to do with POSIX, really,
8756 but it's how Perl getopt works.
8757 * bin/autom4te.in (parse_args): Configure GetOpt with
8758 "permute", too.
8759 * doc/autoconf.texi (Invoking autom4te):
8760 --warning -> --warnings.
8761 * lib/autom4te.in: --warning -> --warnings.
8763 2002-09-28 Akim Demaille <akim@epita.fr>
8765 * doc/autoconf.texi (autom4te.cache): New section.
8767 2002-09-28 Akim Demaille <akim@epita.fr>
8769 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
8770 (Automake-preselections): Update.
8771 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
8773 2002-09-28 Akim Demaille <akim@epita.fr>
8775 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
8776 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
8777 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8778 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
8780 2002-09-28 Akim Demaille <akim@epita.fr>
8782 * tests/torture.at (Configuring subdirectories): Be robust to
8783 users who use config.site to require for a cache: in this case,
8784 the two last configure runs, using two different sets of
8785 arguments, trigger a legitimate error.
8787 2002-09-28 Akim Demaille <akim@epita.fr>
8789 * tests/m4sh.at (Functions Support, Functions and return Support):
8790 New.
8792 2002-09-28 Akim Demaille <akim@epita.fr>
8794 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
8795 autoheader are Perl programs.
8796 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
8797 (autom4te): Specify that the sources are in the $srcdir.
8798 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8800 2002-09-28 Akim Demaille <akim@epita.fr>
8802 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
8803 (tm_zone): Move their rules to...
8804 * lib/autoconf/types.m4: here, using AN_ macros.
8805 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8806 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8807 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8808 * lib/autoconf/programs.m4: here.
8809 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
8810 (ETAGS_FOR_AUTOCONF): New.
8811 Use it.
8813 2002-09-28 Akim Demaille <akim@epita.fr>
8815 * lib/autoconf/autoscan.m4: New file.
8816 * lib/autoconf/autoconf.m4: Include it.
8817 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
8818 that were listed in the original autoscan.list.
8819 * lib/autoconf/headers.m4: Similarly with headers.
8820 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8821 (.m4.m4f): Don't pass --prepend-include, since that's done by
8822 tests/autom4te itself.
8823 * lib/autoscan/Makefile.am: Include freeze.mk.
8824 (autoscan.list): New target --this file is no longer a source.
8825 (autoscan.pre): New file.
8827 2002-09-28 Akim Demaille <akim@epita.fr>
8829 * bin/autoscan.in (@kinds): Make them singular.
8830 Adjust all uses.
8831 (&init_tables): When --debug, report the list of rules to ease
8832 tracking changes in autoscan.list.
8833 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8835 2002-09-28 Akim Demaille <akim@epita.fr>
8837 * lib/autoscan/functions, lib/autoscan/headers,
8838 * lib/autoscan/identifiers, lib/autoscan/makevars,
8839 * lib/autoscan/programs: Merge into...
8840 * lib/autoscan/autoscan.list: this.
8841 * bin/autoscan.in (&init_tables): Adjust.
8843 2002-09-28 Akim Demaille <akim@epita.fr>
8845 * lib/autoscan/functions, lib/autoscan/headers,
8846 * lib/autoscan/identifiers, lib/autoscan/makevars,
8847 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8848 `functions' line is now prefixed with `function:'.
8849 * bin/autoscan.in (&init_tables): Adjust.
8851 2002-09-28 Akim Demaille <akim@epita.fr>
8853 From now on, autoscan files must always map a macro name to a
8854 word: there is no `default' macro for autoscan.
8856 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8857 all.
8858 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8859 explicit.
8861 2002-09-28 Akim Demaille <akim@epita.fr>
8863 * bin/autoscan.in (%c_keywords): Remove.
8864 (&used): Keep only track of the words we might be interested in.
8865 (&output_kind): It is no longer needed to look for non active
8866 checks.
8868 2002-09-27 Akim Demaille <akim@epita.fr>
8870 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
8871 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
8872 * lib/autoscan/functions: Adjust.
8873 * doc/autoconf.texi (Particular Functions): Adjust.
8875 2002-09-27 Akim Demaille <akim@epita.fr>
8877 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8878 from /tmp.
8879 Thanks to Bill Moseley and Paul Eggert.
8880 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8881 the tmpdir must be created.
8882 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8883 dir be in the build tree, instead of $TMPDIR.
8885 2002-09-27 Akim Demaille <akim@epita.fr>
8887 * bin/autoscan.in: Improve the comments.
8888 (&parse_args): Drop obsolete undocumented options.
8889 (&output_kind): Output warnings.
8890 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
8891 (getwd): Trigger a warning.
8893 2002-09-26 Akim Demaille <akim@epita.fr>
8895 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8896 Reported by Ralf Corsepius.
8897 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8899 2002-09-26 Akim Demaille <akim@epita.fr>
8901 Single suffix rules and seperated dependencies are not portable.
8903 * doc/autoconf.texi (Installation Directory Variables): Update.
8904 (Limitations of Make): Some about `Single Suffix Rules and
8905 Separated Dependencies'.
8906 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8907 (ifnames, autoscan, autom4te): Un-factor into several rules.
8909 2002-09-25 Paul Eggert <eggert@twinsun.com>
8911 * BUGS (Interoperability bugs): New section. Mention libtool
8912 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8914 2002-09-24 Paul Eggert <eggert@twinsun.com>
8916 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8917 make handles suffix-rules differently from GNU make.
8919 * bin/Makefile.am (SUFFIXES, .in): Remove.
8920 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8921 Move the body of the old .in rule here.
8923 2002-09-16 Akim Demaille <akim@epita.fr>
8925 i960 compilers create `b.out' files by default.
8926 Reported by Ralf Corsepius.
8928 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8929 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8931 2002-09-13 Paul Eggert <eggert@twinsun.com>
8933 * doc/autoconf.texi (Particular Headers): Remove obsolete
8934 reference to `struct timezone' in the description of
8935 AC_HEADER_TIME.
8937 2002-09-13 Akim Demaille <akim@epita.fr>
8939 Version 2.54.
8941 * config/config.sub, config/config.guess: Update.
8942 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8943 * Makefile.am: Adjust.
8945 2002-09-13 Akim Demaille <akim@epita.fr>
8947 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8948 reading config.log when the compiler is rejected.
8949 Suggested by Guido Draheim.
8951 2002-09-13 Akim Demaille <akim@epita.fr>
8953 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8954 (chdir_init) might hang when stat'ing mounted directories.
8955 Reported by Vance Shipley.
8957 2002-09-12 Akim Demaille <akim@epita.fr>
8959 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8960 the lists.
8962 2002-09-12 Akim Demaille <akim@epita.fr>
8964 * doc/autoconf.texi (Defining Symbols): Present two different
8965 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8966 difference between 1 argument calls, and 2-3 argument calls.
8968 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8970 * doc/autoconf.texi: Review grammar and punctuation.
8972 2002-09-11 Paul Eggert <eggert@twinsun.com>
8974 * doc/autoconf.texi: Fix minor formatting, spelling, and
8975 grammatical typos.
8976 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8977 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8978 is obsolescent.
8980 2002-09-11 Akim Demaille <akim@epita.fr>
8982 * doc/autoconf.texi (Questions): Rename as...
8983 (FAQ): this.
8984 (Defining Directories): New.
8986 2002-09-09 Akim Demaille <akim@epita.fr>
8988 * doc/autoconf.texi (Making testsuite Scripts): Update.
8989 Suggested by Nishio Futoshi.
8991 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8993 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8994 plain `@' is wanted.
8996 2002-09-09 Akim Demaille <akim@epita.fr>
8998 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8999 `duplicates', since the algorithm was too naive and could keep
9000 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
9001 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9002 Reported by Ralf Corsepius.
9003 * tests/torture.at (Configuring subdirectories): Exercise these
9004 cases.
9006 2002-09-09 Akim Demaille <akim@epita.fr>
9008 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
9009 looking for a replacement file.
9010 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9011 directory is relative.
9012 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9013 directory definition.
9014 Reported by Andreas Schwab and Jim Meyering.
9016 2002-09-06 Akim Demaille <akim@epita.fr>
9018 * doc/autoconf.texi (Setting Output Variables): Clarify what
9019 precious variables are.
9020 Suggested by Pontus Skoeld.
9022 2002-09-05 Akim Demaille <akim@epita.fr>
9024 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9025 (ifnames, autoscan, autom4te): Since we don't only depend on
9026 configure.ac variables (such as VERSION etc.), but also on prefix
9027 and so forth, depend on Makefile, not configure.ac.
9028 Reported by Alexandre Duret-Lutz.
9029 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9031 2002-09-05 Kevin Ryde <user42@zip.com.au>
9033 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9034 doesn't seem to be confined to ia64, just say "some versions".
9036 2002-09-04 Akim Demaille <akim@epita.fr>
9038 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9039 Automake 1.6c.
9040 * Makefile.am (maintainer-clean-local): Remove.
9041 (MAINTAINERCLEANFILES): Remove COPYING.
9043 2002-09-03 Paul Eggert <eggert@twinsun.com>
9045 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9046 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9047 Brinkmann.
9049 2002-09-03 Akim Demaille <akim@epita.fr>
9051 * configure.ac: Bump to 2.53d.
9052 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9053 as of today, on Automake's team suggestion.
9055 2002-09-03 Akim Demaille <akim@epita.fr>
9057 Version 2.53c.
9059 2002-09-02 Akim Demaille <akim@epita.fr>
9061 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9062 SITE_MACRO_DIR.
9063 * configure.ac: Disable SITE_MACRO_DIR.
9065 2002-09-02 Jim Meyering <meyering@lucent.com>
9067 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9068 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9069 Also, tweak grammar: s/make sure to/be sure to/.
9071 2002-09-02 Paul Eggert <eggert@twinsun.com>
9073 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9074 directory names are generally preferable to physical names.
9076 2002-09-02 Akim Demaille <akim@epita.fr>
9078 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9079 Reported by Raja R. Harinath.
9080 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9081 * bin/autoupdate.in: Use error instead of die.
9083 2002-09-01 Paul Eggert <eggert@twinsun.com>
9085 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9086 ordinary shell concatenation rather than echo+tr+sed command that
9087 runs afoul of a long-line-related sed bug in Solaris 8.
9089 * bin/autoheader.in (parse_args): --warning -> --warnings.
9091 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9092 stdout, as traditional "ls" does.
9093 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9094 _AC_COMPILER_EXEEXT_O): Likewise.
9095 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9097 * bin/autoconf.as: Add --prepend-include option. This patch was
9098 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9099 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9101 * bin/autoconf.in, configure: Regenerate.
9103 * doc/autoconf.texi (Special Shell Variables): Mention
9104 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9106 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9107 MAILPATH and set PS1, PS2, PS4 to default values, to work
9108 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9109 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9110 the Autoconf documentation specifies; fall back to "unset" only if
9111 this fails. Use a shell for-loop for this rather than an m4 loop,
9112 to shorten the output script.
9114 2002-08-30 Paul Eggert <eggert@twinsun.com>
9116 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9117 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9118 for the CDPATH problem. Document PWD.
9119 (Limitations of Builtins): Document the problem that "cd $foo" and
9120 "ls $foo" may refer to different directories in shells conforming
9121 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9122 example, since the old example is now out of date.
9124 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9125 FOO" and "ls FOO" talk about different directories; this catches
9126 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9127 spaghetti.
9129 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9130 of rolling our own unset.
9131 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9132 in practice we needn't worry about CDPATH if unset doesn't work.
9134 * Makefile.in, aclocal.m4, bin/Makefile.in,
9135 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9136 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9137 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9138 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9139 tests/Makefile.in: Regenerate with Automake 1.6.3.
9141 * config/config.guess, config/config.sub, config/mkinstalldirs:
9142 Update.
9144 * configure: Regenerate with self.
9146 2002-08-30 Kevin Ryde <user42@zip.com.au>
9148 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9149 default output.
9151 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9153 * bin/autom4te.in (Request::load): Correctly test for "do" read
9154 failure.
9156 2002-08-29 Akim Demaille <akim@epita.fr>
9158 * lib/Autom4te/General.pm (&xqx): New.
9159 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9160 hand, which is not portable.
9161 (&error): New.
9162 * bin/autom4te.in: Use them.
9163 Use &error instead of die.
9164 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9165 Adjust.
9167 2002-08-17 Paul Eggert <eggert@twinsun.com>
9169 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9170 default list of compilers to try, since it was long ago superseded
9171 by the ksh fc builtin. Suggested by Steven G. Johnson.
9173 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9175 * doc/autoconf.texi (Invoking autom4te): End the option table,
9176 fixing a bug introduced by the previous patch.
9177 (Limitations of Make): Add a 'target lookup' subentry in the
9178 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9180 2002-07-29 Mark D. Roth <roth@feep.net>
9182 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9183 options and use $AUTOM4TE_PATH.
9184 * doc/autoconf.texi: Remove documentation of autom4te
9185 --include-envvar and --site-macro-subdir options and document
9186 use of $AUTOM4TE_PATH.
9187 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9188 arguments from each language section.
9190 2002-07-29 Paul Eggert <eggert@twinsun.com>
9192 * doc/install.texi: Include copyright symbol in copyright notice.
9194 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9195 Replace with:
9196 (AM_MAKEINFOFLAGS): New macro.
9197 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9198 * Makefile.am (INSTALL): Use the new macros.
9199 Use -o rather than --output, since "missing" does not grok --output.
9201 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9203 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9204 comments do not always work. Never trust the exit status of
9205 `make -k'.
9207 2002-07-24 Kevin Ryde <user42@zip.com.au>
9209 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9210 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9212 2002-07-23 Paul Eggert <eggert@twinsun.com>
9214 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9215 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9216 apparently treats PATH="nonexistent" as if it contained ".".
9217 Bug reported by Stefan `Sec' Zehl.
9219 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9221 * doc/autoconf.texi (Limitations of Make): Mention the special

9343 2002-06-27 Paul Eggert <eggert@twinsun.com>
9345 * config/install-sh: Quote $src. Prefer || to test's -o option,
9346 as per "Limitations of Builtins".

9410 * bin/autom4te.in (warn_forbidden): When rejecting a token,

9419 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

9473 version of Autoconf that is discussed.
9475 2002-05-22 Paul Eggert <eggert@twinsun.com>
9477 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
9478 from the default list of compilers to try. Suggested by
9479 Kate Hedstrom.
9480 * NEWS: Document the above.
9481 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
9483 2002-05-17 Paul Eggert <eggert@twinsun.com>
9485 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9486 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9487 This improves on an earlier suggestion by H. Peter Anvin.
9489 2002-05-16 Paul Eggert <eggert@twinsun.com>
9491 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9492 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9493 Both macros now accept an optional source-dir arg.
9494 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9496 * NEWS: Document this.
9497 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9499 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9500 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9501 not for GNU extensions; this undoes part of the 2000-11-03 change,
9502 reverting to 2.13-compatible behavior.
9503 Add new optional argument DIR.
9504 (AC_FUNC_FNMATCH_GNU): New macro.
9506 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9508 2002-05-08 Paul Eggert <eggert@twinsun.com>
9510 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9511 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9512 and it causes a 'test' syntax error if it fails.
9513 Bug reported by Stephen Gildea.
9515 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9516 If prototypes are supported, use them to check this at compile-time,
9517 instead of trying to check it at run-time. If we must do a run-time
9518 check, assume that setvbuf is standard when cross-compiling, as
9519 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9520 Bug reported by Paul D. Smith.
9522 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9523 argument specifying location of getloadavg.c. This removes a
9524 FIXME. This idea was taken from Jim Meyering's implementation in
9525 textutils.
9526 * doc/autoconf.texi (Particular Functions): Document this.
9527 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9528 that's what the code does; this fixes a bug reported by
9529 Paul D. Smith.
9531 2002-05-03 Akim Demaille <akim@epita.fr>
9533 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9534 autopoint instead of gettextize.
9535 ($uses_alocal): Rename as...
9536 ($uses_aclocal): this.
9537 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9538 Suggested by Bruno Haible.
9540 2002-05-03 Akim Demaille <akim@epita.fr>
9542 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9544 2002-04-29 Paul Eggert <eggert@twinsun.com>
9546 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9547 files to be 1 second older; just set them to be the same time.
9548 Also, sleep 1 second after the first aclocal, to work around
9549 problems with sub-second time stamps on the input files.
9551 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9553 * doc/autoconf.texi: Mention "set -e -x" lossage
9554 under node "Limitations of Builtins".
9556 2002-04-29 Akim Demaille <akim@epita.fr>
9558 * doc/install.texi: Better wording for setting variables when
9559 running configure.
9560 From Christian Cornelssen.
9562 2002-04-29 Akim Demaille <akim@epita.fr>
9564 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9565 of lack of $LINENO support, then the test will compare the $LINENO
9566 in testsuite vs. the lineno in the test file. This is wrong, of
9567 course.
9568 Be sure to protect it.
9569 Reported by Patrick Welche.
9571 2002-04-25 Akim Demaille <akim@epita.fr>
9573 * doc/autoconf.texi (Obsolete Macros): Typo.
9574 Reported by Vladimir Volovich.
9576 2002-04-25 Akim Demaille <akim@epita.fr>
9578 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9579 than some of the input files, hence, on the second run of aclocal,
9580 if some of its input are younger, make them older.
9581 Suggested by Paul Eggert.
9583 2002-04-25 Akim Demaille <akim@epita.fr>
9585 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9586 Thanks to Paul Eggert.
9588 2002-04-25 Akim Demaille <akim@epita.fr>
9590 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9591 and ac_subst_vars be sh variables containing the list of
9592 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9593 DEFAULT diversion.
9594 (_AC_INIT_PREPARE): Use them to log them.
9595 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9596 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9597 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9598 _AC_SUBST_FILES and _AC_SUBST_VARS.
9599 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9601 2002-04-24 Akim Demaille <akim@epita.fr>
9603 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9604 autoheader, so that automake does not complain about a missing
9605 config.h.in that was to be created.
9607 2002-04-23 Akim Demaille <akim@epita.fr>
9609 * bin/autoheader.in (parse_args): --warning takes an argument.
9610 Fixes PR/220.

9661 * doc/autoconf.texi: Follow the outline suggested in the GNU
9662 Sample Texts sections of the Texinfo 4.2 manual. Most
9663 importantly, this makes sure that the copyright notices appear in
9664 all output formats. You probably need Texinfo 4.2 to generate

9709 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9710 part into...
9711 (_AS_PREPARE): this new macro.
9712 (AS_PREPARE): New.
9713 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9714 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9716 Adjust Autoconf and Autotest.
9718 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9719 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9720 * lib/autotest/general.m4 (AT_INIT): Likewise.
9721 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9722 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9723 AS_SHELL_SANITIZE.
9725 Use this M4sh to generate Autoconf's shell scripts.
9727 * tests/wrapsh.as: New, precursor of wrapsh.in.
9728 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9729 on Autotest and M4sh.
9730 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9731 (wrapsh.in): New target.
9732 * bin/autoconf.as: New, precursor of autoconf.in.
9733 (autoconf.in): New target.
9735 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
9737 * doc/autoconf.texi (Limitations of Make): Mention the issue
9738 with indented comments in rules.
9740 2002-04-09 Andreas Schwab <schwab@suse.de>
9742 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9743 ac_top_builddir when setting ac_abs_top_builddir.
9745 2002-04-06 Kevin Ryde <user42@zip.com.au>
9747 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9748 (Portable Shell): Cross reference to Systemology.
9750 2002-04-05 Akim Demaille <akim@epita.fr>
9752 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9753 directories when descending in a SUBDIRS.
9754 Reported by Ezra Peisach.
9756 2002-04-04 Andreas Schwab <schwab@suse.de>
9758 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9759 contains no literal separators.
9761 2002-04-03 Akim Demaille <akim@epita.fr>
9763 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9764 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9765 Use dnl, not the KILL diversion.
9766 Extracted from...
9767 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9768 (AC_CONFIG_LINKS): here.
9769 Adjust.
9770 Don't use the KILL diversion, as it kills spurious output, which
9771 results in failures being hidden.
9772 Use m4_defn where appropriate.
9773 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9774 after the second argument.
9775 Use m4_defn.
9776 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9777 syntax, as it is provided by M4sugar.
9778 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9780 2002-04-03 Andreas Schwab <schwab@suse.de>
9782 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9783 expanded if $# <= 2.
9785 * bin/autoreconf.in (autoreconf): Run automake after rerunning
9786 aclocal.
9788 2002-04-03 Akim Demaille <akim@epita.fr>

9791 (_AC_COMPILER_EXEEXT_REJECT): New.
9792 Also recognize *.bb and *.bbg as compilation byproducts.
9793 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9794 (_AC_COMPILER_OBJEXT): Use them.
9795 Fixes Debian #138666.
9797 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9799 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9801 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9802 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9803 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9804 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9805 (AC_C_CONST): Same.
9806 (AC_C_INLINE): Same.
9807 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
9808 * doc/autoconf.texi, NEWS: Document.
9809 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9810 AC_C_CROSS.
9812 2002-04-02 Akim Demaille <akim@epita.fr>
9814 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
9815 _AS_MKDIR_P_PREPARE.
9817 2002-03-28 Kevin Ryde <user42@zip.com.au>
9819 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9820 to avoid versions of HP C which don't allow that.
9822 2002-03-27 Paul Eggert <eggert@twinsun.com>
9824 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9825 (AS_SHELL_SANITIZE): Invoke it.
9826 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9828 2002-03-26 Akim Demaille <akim@epita.fr>
9830 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9832 2002-03-26 Akim Demaille <akim@epita.fr>
9834 * doc/autoconf.texi (Introduction): The GNATS base moved.
9836 2002-03-25 Paul Eggert <eggert@twinsun.com>
9838 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9839 as POSIX requires, as it doesn't work with Zsh.
9840 * doc/autoconf.texi (Assignments): Document the problem.
9842 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9844 * doc/autoconf.texi (Limitations of Make): Mention more issue
9845 about VPATH, overriding of macros in sub-makes, and handling of
9846 SHELL.
9848 2002-03-21 Paul Eggert <eggert@twinsun.com>
9850 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9851 problem with here-document buffer boundaries.
9853 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9854 when reinvoking the shell, to work around problems with installers
9855 who put strange things like "cd" commands in their environments.
9857 2002-03-19 Akim Demaille <akim@epita.fr>
9859 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9860 From Aaron Ucko.
9862 2002-03-19 Akim Demaille <akim@epita.fr>
9864 * bin/autoscan.in (scan_file): Specify the location in `&used'
9865 invocations.
9866 From Nicolas Joly.
9868 2002-03-19 Akim Demaille <akim@epita.fr>
9870 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9871 From Nishio Futoshi.
9873 2002-03-19 Akim Demaille <akim@epita.fr>
9875 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9877 2002-03-18 Paul Eggert <eggert@twinsun.com>
9879 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9880 (Limitations of Usual Tools): Add mkdir section.
9882 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9883 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9884 back on AS_DIRNAME to compute prefixes otherwise; this is
9885 roughly what mkinstalldirs does. That way, we need not have
9886 our own filename disassembler. The old disassembler did not
9887 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9889 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9890 Create at_test_all by a series of assignments,
9891 not by a single assignment of a long string. The latter causes ksh
9892 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9893 presumably because of a buffer overrun.
9895 2002-03-14 Paul Eggert <eggert@twinsun.com>
9897 * lib/autotest/general.m4 (at_times_skip):
9898 Renamed from at_times. Now a boolean.
9899 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9900 says 'times: not found'.
9902 2002-03-14 Akim Demaille <akim@epita.fr>
9904 * bin/autoreconf.in (&study_gettextize): New.
9905 (&autoreconf): Handle newest gettextize.
9906 Rerun aclocal if needed.
9907 Suggested by Andreas Schwab.
9909 2002-03-13 Akim Demaille <akim@epita.fr>
9911 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9913 2002-03-13 Akim Demaille <akim@epita.fr>
9915 * doc/autoconf.texi (Header Portability): New.
9916 Add information about stdint.h and inttypes.h from Paul Eggert.
9918 2002-03-13 Akim Demaille <akim@epita.fr>
9920 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9921 -p'.
9922 From Bob Proulx.
9924 2002-03-12 Akim Demaille <akim@epita.fr>
9926 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9927 m4_require.
9929 2002-03-11 Andreas Schwab <schwab@suse.de>
9931 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9932 does not do it if --with-lispdir is given.
9934 2002-03-08 Akim Demaille <akim@epita.fr>
9936 Version 2.53.
9938 2002-03-08 Akim Demaille <akim@epita.fr>
9940 * doc/autoconf.texi (Subdirectories): Clarify that the
9941 subdirectory should exist.
9943 2002-03-08 Akim Demaille <akim@epita.fr>
9945 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9947 2002-03-08 Akim Demaille <akim@epita.fr>
9949 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9950 aliases the actual variables, and modifications of the former
9951 affect the latter.
9953 2002-03-08 Akim Demaille <akim@epita.fr>
9955 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9956 because of C-c: have m4 output in tmp files, then mv them.
9958 2002-03-08 Akim Demaille <akim@epita.fr>
9960 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9961 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9962 * bin/ifnames.in: Copyright update.
9964 2002-03-08 Akim Demaille <akim@epita.fr>
9966 * doc/autoconf.texi (Invoking autom4te): New.
9968 2002-03-05 Akim Demaille <akim@epita.fr>
9970 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9971 Kevin Ryde.
9973 2002-03-05 Akim Demaille <akim@epita.fr>
9975 Version 2.52i.
9977 2002-03-04 Akim Demaille <akim@epita.fr>
9979 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9980 * lib/autoconf/general.m4 (AC_INIT): More informative error
9981 message for LIBOBJ.
9983 2002-03-04 Akim Demaille <akim@epita.fr>
9985 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9986 parallel builds.
9988 2002-03-04 Akim Demaille <akim@epita.fr>
9990 * doc/autoconf.texi (Transforming Names): Equality between target
9991 and host is irrelevant.
9992 (Specifying Names, Canonicalizing): Remove all references to the
9993 backward compatibility hooks. Rather, collect them all into...
9994 (Hosts and Cross-Compilation): this new section.
9995 * doc/install.texi (System Type): Ditto.
9996 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9997 that `--host' implies cross-compilation.
9999 2002-03-04 Akim Demaille <akim@epita.fr>
10001 * doc/autoconf.texi (Evaluation Macros): New.
10002 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10003 useless.
10004 (_m4_foreach): Define the variant with immediate evaluation so
10005 that it contains exactly the items, not an expression which
10006 evaluation is the current item.
10007 (m4_re_string, m4_re_word): Don't over quote them.
10009 2002-03-04 Akim Demaille <akim@epita.fr>
10011 Instead of having stacking `shift's evaluated at the end, let
10012 `foreach' loops immediately evaluate them.
10014 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10015 $*. This is the n-th time I change my mind, but hopefully this is
10016 the last...
10017 (m4_lquote): New.
10018 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10019 efficient.
10020 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10021 it was only a hack for m4_text_wrap.
10022 (m4_car2): Remove, replaced by...
10023 (m4_cdr): New.
10024 (_m4_foreach): Adjust.
10025 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10026 m4_bpatsubst for clarification.
10028 2002-03-04 Akim Demaille <akim@epita.fr>
10030 * doc/autoconf.texi (Changequote is Evil): New.
10032 2002-03-03 Kevin Ryde <user42@zip.com.au>
10034 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
10035 on old systems like SunOS.

10043 of messages.
10045 2002-02-28 Akim Demaille <akim@epita.fr>
10047 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
10048 message to be sent.

10057 From Akinori Musha.
10059 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
10061 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
10062 translate \r\n to \n.
10064 2002-02-07 Akim Demaille <akim@epita.fr>
10066 Version 2.52h.
10068 2002-02-07 Akim Demaille <akim@epita.fr>
10070 Fix Autoconf PR/209.
10071 Also reported by Frank Denis.
10073 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
10075 2002-02-07 Akim Demaille <akim@epita.fr>
10077 Fix Autoconf PR/207:
10078 AC_PREFIX_PROGRAM fails with dashed program names
10080 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
10081 variable when looking for the prefix program.
10082 Now it also works for shell variables.
10084 2002-02-07 Akim Demaille <akim@epita.fr>
10086 * doc/autoconf.texi (Limitations of Builtins): More about
10087 case/esac.
10089 2002-02-06 Akim Demaille <akim@epita.fr>
10091 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
10092 case/esac, some shells don't support it.
10093 Reported by Zack Weinberg.
10094 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
10096 2002-02-06 Akim Demaille <akim@epita.fr>
10098 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
10099 sure not to introduce newlines in at_groups.
10100 * lib/autotest/Makefile.am (autotest.m4f): Typo.
10102 2002-02-06 Akim Demaille <akim@epita.fr>
10104 * tests/torture.at (Configuring subdirectories): Skip if aclocal
10105 is not available.
10107 2002-02-05 Paul Eggert <eggert@twinsun.com>
10109 * doc/autoconf.texi (Specific Compiler Characteristics):
10110 Describe HP-UX cc bug workaround more accurately.
10111 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
10112 not unsigned long.
10113 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
10114 cross-compilers, too. This undoes some of the most recent change
10115 to this file.
10117 2002-02-05 Akim Demaille <akim@epita.fr>
10119 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
10120 to make sure they are up to date when `check' is run.
10122 2002-02-05 Akim Demaille <akim@epita.fr>
10124 * doc/autoconf.texi (Making testsuite Scripts): Document
10125 package.m4.
10127 2002-02-05 Akim Demaille <akim@epita.fr>
10129 * lib/freeze.mk: New.
10131 2002-02-05 Akim Demaille <akim@epita.fr>
10133 Implement `autom4te --freeze'.
10135 * bin/autom4te.in (&freeze): New.
10136 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
10137 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
10139 2002-02-05 Akim Demaille <akim@epita.fr>
10141 * bin/autom4te.in (&parse_args): Implement `frozen files are
10142 optional are the sum of the previous files on the command line'.
10143 Also, pass `--reload-state=' on them, so...
10144 (handle_m4): don't.
10145 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10146 (M4sh): Rely on M4sugar.
10147 (Autotest, M4sh, M4sugar): Use frozen files.
10149 2002-01-31 Akim Demaille <akim@epita.fr>
10151 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
10152 * doc/autoconf.texi (Initializing configure): Adjust.
10154 2002-01-30 Akim Demaille <akim@epita.fr>
10156 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
10157 alphanumeric to `-' instead of `_'.
10159 2002-01-30 Akim Demaille <akim@epita.fr>
10161 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10162 for plain code, the other for cross-compilation code. The latter
10163 is now run with GCC only.
10164 * doc/autoconf.texi (Compilers and Preprocessors): New.
10166 2002-01-30 Akim Demaille <akim@epita.fr>
10168 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
10169 values.
10170 * doc/autoconf.texi (Initializing configure): Explain how to
10171 change AC_INIT default values.
10173 2002-01-29 Akim Demaille <akim@epita.fr>
10175 * tests/torture.at (Configuring subdirectories): Use configure.in,
10176 so that aclocal 1.4 works.
10177 Reported by Alexandre Duret-Lutz and Larry Schmitt.
10179 2002-01-28 Akim Demaille <akim@epita.fr>
10181 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10182 needs an argument.
10184 2002-01-28 Akim Demaille <akim@epita.fr>
10186 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10187 AUTOTEST_PATH *after* it was set.
10188 Don't put `.' in the PATH: the user should be precise and `./' if
10189 needed. In addition, given that the test suite does some `cd', if
10190 `.' is in the path, the `tested programs' sections will report
10191 programs found in the test suite's directory, while during the
10192 tests (performed in their own directory), these programs are no
10193 longer visible. In other words, the results is confusing and
10194 useless.
10195 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10197 2002-01-24 Akim Demaille <akim@epita.fr>
10199 Version 2.52g.
10201 2002-01-24 Akim Demaille <akim@epita.fr>

10270 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10271 and PACKAGE_BUGREPORT from here...
10272 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10273 arguments.
10274 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10275 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

10299 2001-12-14 Akim Demaille <akim@epita.fr>
10301 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10302 trailing files, don't apply `-rf' to files which might not be
10303 created by configure (core, core.*, and *.core), but just `rm -f'.
10304 Suggested by Jonathan Kamens.
10306 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10308 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

10321 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
10322 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10324 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
10326 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
10327 C/Fortran linking on HP/UX, by extracting the Fortran library
10328 search path from the LPATH line in the $F77 -v output.
10330 2001-12-12 Kevin Ryde <user42@zip.com.au>
10332 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10333 forbidden file descriptors table.
10335 2001-11-26 Akim Demaille <akim@epita.fr>
10337 * bin/autoscan.in (%c_keywords): Build it at top level.
10338 Map to 1 in order to simplify its uses.
10340 2001-11-26 Akim Demaille <akim@epita.fr>
10342 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10343 Remove $filepath, useless.
10344 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10345 variables, they are really part of the tokens.
10346 Split the input line on spaces and then look for tokens.
10347 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10348 because of `lex$U.$(OBJEXT)'.
10349 (&scan_files): Use "@list" instead of join.
10350 * doc/Makefile.am (CLEANFILES): Add *.fns.
10352 2001-11-26 Akim Demaille <akim@epita.fr>
10354 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:

10372 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10374 2001-11-26 Akim Demaille <akim@epita.fr>
10376 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10377 Before, having a line containing the opening of a multi line
10378 comment made the whole line be ignored.
10380 2001-11-26 Akim Demaille <akim@epita.fr>
10382 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10383 (testsuite Scripts): Be one of its subsection.
10384 (Autotest Logs): New.
10386 2001-11-26 Akim Demaille <akim@epita.fr>
10388 Test groups are now run two directories deeper.
10390 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10391 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10392 at_top_builddir.
10393 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10394 top_srcdir, builddir and top_builddir.
10395 Use `at_*dir' relatively to the directory containing the
10396 suite, use `*dir' when relatively to the current group dir.
10398 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10400 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10401 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10402 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10403 spelling errors.
10405 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10407 * doc/autoconf.texi (Using System Type): Add an example of `case
10408 $host' usage so people quit using `case $target' everywhere.
10410 2001-11-22 Akim Demaille <akim@epita.fr>
10412 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10413 spotted by Jim Meyering.
10415 2001-11-16 Paul Eggert <eggert@twinsun.com>
10417 This patch implements a `long double' suggestion by Oliver Kiddle.
10419 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10420 static, to catch errors if the value isn't known at compile-time
10421 and the compiler supports dynamic arrays. Change its name from
10422 `_array_' to `test_array' to avoid potential name clashes.
10423 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10424 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10425 better than double. Catch a bug in GCC 2.95.2 x86.
10426 * doc/autoconf.texi (C Compiler): Document the above.
10427 * NEWS: Likewise.
10429 2001-11-13 Akim Demaille <akim@epita.fr>
10431 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10432 hand.
10433 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10435 2001-11-13 Akim Demaille <akim@epita.fr>
10437 * lib/autotest/general.m4 (AT_INIT): After having run the test
10438 group, go back to the initial directory, not to at_suite_dir.
10440 2001-11-13 Akim Demaille <akim@epita.fr>
10442 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10443 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10444 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10445 option.
10446 (AT_CHECK_CONFIGURE): Use absolute paths.
10447 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10448 The problem is still the old one: there is no means in M4 (that I
10449 know about) to create a defining macro, because there is no means
10450 to create `$1' etc., therefore, the defining macro ``swallows''
10451 all the arguments meant to the defined macro.
10453 2001-11-13 Akim Demaille <akim@epita.fr>
10455 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10456 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10457 configure.ac.
10458 * tests/aclocal.m4: Remove, as it is no longer used.
10460 2001-11-13 Akim Demaille <akim@epita.fr>
10462 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10463 variable names when referring to a single test group, or to
10464 `suite' when referring to the whole test suite.
10465 `at_last_test' is removed: m4 compute at_format itself.
10466 (at_stdout, at_stder1, at_stderr): New variables.
10467 (AT_CHECK): Use them.
10469 2001-11-13 Akim Demaille <akim@epita.fr>
10471 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10472 in PATH.
10473 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10474 Do it as soon as a test fails, don't wait till the end of the test
10475 suite.
10476 Don't remove $as_me.[0-9]*, since these files no longer exist.
10478 2001-11-13 Akim Demaille <akim@epita.fr>
10480 * tests/tools.at: Use absolute paths, since we are no longer run
10481 in place.
10483 2001-11-13 Akim Demaille <akim@epita.fr>
10485 Now that tests are running in their own private dir, there is no
10486 need to list the files to remove at the end of tests groups.
10488 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10489 (AT_data_files, at_data_files): Remove.
10490 (AT_CLEANUP, AT_DATA): Simplify.
10491 (AT_INIT): Adjust.
10492 Remove the group dir if !debug && !failed.
10493 * tests/atspecific.m4: Adjust.
10495 2001-11-13 Akim Demaille <akim@epita.fr>
10497 Start a new layout for Autotest: `testsuite' creates
10498 `testsuite.dir' in which the at-check-line etc. files are to be
10499 found, and `testsuite.dir/003' where the test group 3 is run.
10501 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10502 at_check_line_file, at_format, at_test_normalized, at_group_dir
10503 are new variables.
10504 Create the directories.
10505 Use absolute paths for at- files.
10506 (AT_CHECK): Adjust.
10508 2001-11-11 Michael Matz <matz@kde.org>
10510 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10511 (m4_car2): New.
10512 (m4_car): Properly quote arguments.
10514 2001-11-13 Akim Demaille <akim@epita.fr>
10516 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10517 with stricter rules on LIBOBJS.
10519 2001-11-12 Paul Eggert <eggert@twinsun.com>
10521 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10522 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10523 __PROTOTYPES too.
10525 2001-11-12 Akim Demaille <akim@epita.fr>
10527 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10529 2001-11-12 Akim Demaille <akim@epita.fr>
10531 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10532 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10533 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10534 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10535 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10536 specify to what the macro should be defined (typically to 1).
10538 2001-11-12 Akim Demaille <akim@epita.fr>
10540 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10541 From Jim Meyering.
10543 2001-11-12 Akim Demaille <akim@epita.fr>
10545 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10546 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10547 definition used by Automake where LEX is +/- "${missing} lex" and
10548 `missing' itself contains variables.
10550 2001-11-12 Akim Demaille <akim@epita.fr>
10552 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10553 Now that M4sh pushes BODY, the comments were output at the end of
10554 the test suites.
10556 2001-11-08 Akim Demaille <akim@epita.fr>
10558 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10559 that we can trace macros from aclocal.m4.
10560 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10561 obsoleted, and redirect to the former anyway.
10562 Reported by Ralf Corsepius.
10564 2001-11-08 Akim Demaille <akim@epita.fr>
10566 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10567 processed only if present.
10568 * tests/torture.at (Configuring subdirectories): Use autoreconf
10569 instead of successive calls to autoconf.
10570 Add a nonexistent subdirectory to exercise the patch above.
10571 Reported by Ralf Corsepius.
10573 2001-11-08 Kevin Ryde <user42@zip.com.au>
10575 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10576 doesn't accept .S files.

10583 * bin/autom4te.in (warn_forbidden): New.
10584 (handle_output): Use it.
10585 Read m4_pattern_forbid with messages.
10587 2001-11-05 Akim Demaille <akim@epita.fr>
10589 * bin/autom4te.in (--normalize): Remove.
10590 * lib/autom4te.in: Adjust.
10592 2001-11-05 Akim Demaille <akim@epita.fr>
10594 * tests/Makefile.am (testsuite): Rename this target as...
10595 ($(TESTSUITE)): this.
10596 From Nicolas Joly.
10598 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10600 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10601 the --prefix option, also remove it's argument.
10603 2001-11-05 Akim Demaille <akim@epita.fr>
10605 * doc/autoconf.texi (testsuite Invocation): Update.

10612 2001-11-03 Akim Demaille <akim@epita.fr>
10614 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10615 (&file_name_is_absolute): New, wrappers around routines from
10616 File::Spec.
10617 Use and export them.
10618 (&find_configure_ac): Optionally take a directory where to look at.
10619 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10620 the arguments.

10630 Add basename, dirname, and fileparse.
10631 (@EXPORT): Adjust.
10632 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10633 Don't look for aclocal flags if we already know aclocal is not
10634 used.
10635 Move aclocal.m4t only if it exists.
10636 Reported by Ezra Peisach.
10638 2001-11-03 Akim Demaille <akim@epita.fr>
10640 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10641 passed on command line, defaulting to ./configure.ac if present.
10642 (&maybe_autoreconf, File::Find): Remove, unused.
10643 (&autoreconf): If autoconf is not used, don't try to trace.
10645 2001-11-02 Akim Demaille <akim@epita.fr>
10647 * configure.ac: Bump to 2.52g.
10649 2001-11-02 Akim Demaille <akim@epita.fr>

10662 Don't run aclocal when aclocal.m4 is not from aclocal.
10663 From Ezra Peisach.
10664 Don't run libtoolize and gettextize if --install is not given.
10666 2001-11-01 Paul Eggert <eggert@twinsun.com>
10668 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10669 be invoked before _AS_LINENO_PREPARE.
10670 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10671 than character ranges.
10673 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10674 invoking AS_BASENAME. Set the locale variables to 'C' if
10675 possible, as POSIX requires this to get the traditional
10676 behavior.
10677 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10679 2001-10-31 Paul Eggert <eggert@twinsun.com>
10681 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10682 with {}, as that triggers a bug in Bash 2.05.
10684 (_AS_LINENO_PREPARE): Use Sed rather than
10685 Awk. Fix the sed prepass to work even if there are multiple
10686 instances of $LINENO on the same line. Do not substitute for
10687 other variables like $LINENOT. Do not check file dates; such a
10688 check is unreliable on sufficiently fast machines, and removing
10689 the check makes the code simpler and more reliable. Check for
10690 output and chmod failures.
10692 * doc/autoconf.texi (Special Shell Variables): Document
10693 the above.
10695 2001-10-31 Akim Demaille <akim@epita.fr>
10697 * tests/Makefile.am (atconfig): Remove this target, Automake
10698 handles it now.
10700 2001-10-31 Akim Demaille <akim@epita.fr>
10702 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10703 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10704 provided, while it is optional.
10705 * configure.ac: Adjust.
10707 2001-10-26 Paul Eggert <eggert@twinsun.com>
10709 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10710 lib/Autom4te/Struct.pm:
10711 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10712 with 5.005_02.
10714 * doc/autoconf.texi (Special Shell Variables): Document some
10715 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10717 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10718 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10719 eval $LINENO is not portable in practice.
10721 2001-10-24 Akim Demaille <akim@epita.fr>
10723 * lib/Autom4te/General.pm (backname): New.
10725 2001-10-24 Akim Demaille <akim@epita.fr>

10733 2.05's use of ANSI quoting in its `set' builtin.
10735 2001-10-22 Paul Eggert <eggert@twinsun.com>
10737 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10738 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10739 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10740 POSIX decided to standardize on the int flavor of strerror_r.
10741 Always do char* test, as there's no reason not to.
10742 Assign to a char* var, to catch strerror_r that returns int*.
10744 * doc/autoconf.texi (Particular Functions):
10745 Document the above changes. Also, document the fact that
10746 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10748 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10750 2001-10-20 Akim Demaille <akim@epita.fr>

10758 unchanged, remove the source.
10759 (&up_to_date_p): Don't be verbose, be debug.
10760 * bin/autoreconf.in: No longer support --m4dir.
10761 (&autoreconf): Display the full path of the configure.ac we are
10762 studying.
10763 Trace it only once.
10764 Be sure to honor --force with gettextize.
10765 Always run aclocal.
10766 * doc/autoconf.texi: Adjust.
10768 2001-10-20 Akim Demaille <akim@epita.fr>
10770 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10771 Remove, dead.
10772 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10773 `intl' is already present, as it refuses unless --force.
10774 (&parse_args): Use -I, --include instead of the old Autoconf
10775 options.
10776 ($localdir, $autoconf_dir): Remove.
10777 (@include): New.

10790 * tests/torture.at (#define header templates): Adjust.
10792 2001-10-19 Akim Demaille <akim@epita.fr>
10794 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10795 comment, explain how to install automatic mode selection.
10796 From Russ Allbery.
10798 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10800 * bin/autoreconf.in (autoreconf): Display the path to the
10801 configure.ac being studied.
10803 2001-10-18 Paul Eggert <eggert@twinsun.com>
10805 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10806 long, to work around a bug in the HP C compiler version HP92453-01
10807 B.11.11.23709.GP.
10809 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10810 (AS_BASENAME_EXPR): New macro.
10811 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10812 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10813 and fall back on 'sed' only if the other two fail. This makes
10814 AS_BASENAME act more like AS_DIRNAME.
10815 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10816 contains white space.
10817 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10818 Use AS_DIRNAME, since I think it's now DOS-friendly.
10819 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10820 Allow "dirname //FOO" to return either / or //, as POSIX allows
10821 either behavior.

10825 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

10827 From Eric Sharkey.

10831 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
10832 m4_define, since...

10871 bother with $force since...
10872 * lib/Autom4te/General.pm: does.
10874 2001-10-08 Akim Demaille <akim@epita.fr>
10876 * bin/autoreconf.in: Rewrite in Perl.
10877 * configure.ac: Adjust.

10963 ourselves with CONFIG_SHELL.
10965 2001-10-05 Paul Eggert <eggert@twinsun.com>
10967 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
10968 doesn't exist. Remove *.tmp, as a .tmp file is created during the

11039 Don't use nested parenthesization. This patch was originally

11041 but somehow it didn't get incorporated then.
11042 * doc/autoconf.texi (Limitations of Usual Tools):
11043 Clarify remark about sed and nested parenthesization.
11045 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
11046 Report an error if the size cannot be determined even though
11047 the type exists.
11048 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11049 Check for `expr' arithmetic overflow, and for compilation failure,
11050 and invoke a new argument $4 if either is discovered.
11051 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
11052 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
11054 2001-09-28 Akim Demaille <akim@epita.fr>

11084 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
11085 (AC_PROG_CPP requires AC_PROG_CC): here and...
11086 * tests/fortran.at (GNU Fortran 77): there.
11087 * doc/autoconf.texi (autoconf Invocation): Fix the example:
11088 AC_TRY_RUN is about compilation, not shell commands.

11094 Raja R Harinath:
11095 Be sure to detect when $LINENO always returns the same value.
11096 Look for the original script, basename($0) is certainly not
11097 enough.
11098 Pass the CLI arguments to `$as_me.lineno'.

11102 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

11192 * lib/autoconf/autotest.m4: Create `package.m4'.
11193 * tests/Makefile.am (package.m4): Remove.
11195 2001-09-22 Akim Demaille <akim@epita.fr>
11197 Rely on `$LINENO' when possible instead of `__oline__'.
11199 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
11200 `$LINENO' support replacement when not supported.
11201 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
11202 them explicitly to be sure they are not output before this section
11203 (via m4_require). Cosmetic only.

11212 character (u: -> ue) in a code comment.
11213 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
11214 it works.
11216 2001-09-21 Akim Demaille <akim@epita.fr>
11218 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
11219 Suggested by Jim Meyering.
11221 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11223 * lib/autoconf/programs.m4: Use extensions listed in
11224 $ac_executable_extensions when looking for programs.

11228 * lib/autoconf/general.m4: Fix a small Englisho.

11237 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

11240 * lib/autotest/general.m4: Replace occurrences of ':' in

11243 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11245 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
11246 arguments. Fixed a typo.
11248 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11250 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

11253 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11255 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
11256 * bin/autoupdate.in: Ditto.
11257 * bin/autoheader.in: Reworded a few comments.

11262 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11264 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
11265 already have $file). Set output files to binary mode (helps avoid
11266 CR issues on DOSish systems).
11268 2001-09-19 Akim Demaille <akim@epita.fr>
11270 * lib/autotest/general.m4: Englishoes.
11271 From Tim Van Holder and Alexey Mahotkin.
11273 2001-09-18 Paul Eggert <eggert@twinsun.com>
11275 * doc/autoconf.texi (Common Shell Constructs): New node,
11276 documenting AS_DIRNAME.
11277 (Limitations of Usual Tools): Refer to it when discussing dirname.
11278 Also, update discussion of POSIX standard to reflect latest draft.
11280 * lib/autoconf/c.m4:
11281 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11283 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11284 Do not pass a first argument with leading '-'
11285 to expr, by parenthesizing initial integers that might be negative.
11287 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11288 now merely checks whether it is an error to pass an argument
11289 to getpgrp.
11291 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11292 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11293 whether it is a (compile-time) error to pass an argument to
11294 getpgrp. This simpler test supports the revised documentation,
11295 and is all that AC_FUNC_GETPGRP's users really need.
11297 2001-09-18 Akim Demaille <akim@epita.fr>
11299 * doc/autoconf.texi (Limitations of Make) <$<>: New.
11301 2001-09-18 Akim Demaille <akim@epita.fr>

11309 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11310 correctly.
11311 Add test for AS_BASENAME.
11312 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11313 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11314 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11315 * tests/base.at: Fixed the expected responses. The old ones were
11316 one line out...
11317 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11318 the documentation claims it should (and how it behaved in 2.13).
11320 2001-09-18 Akim Demaille <akim@epita.fr>
11322 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11323 the AC_CONFIG_COMMANDS invocation.
11324 This also solves the name clash problems.
11325 Don't set the package's ID.
11326 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11327 No longer to be shipped.
11328 (version.in): Remove.
11329 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11330 * lib/autoconf/status.m4: Adjust.
11331 Use `m4_PACKAGE_STRING'.
11332 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11333 the only optional argument is the name of the test suite.
11334 Expect `package.m4' to define the package signature.
11335 * lib/autom4te.in (Autotest): Add `package.m4?'.
11336 * tests/Makefile.am (package.m4): New.
11337 * tests/suite.at: ifnames is a victim.
11339 2001-09-18 Akim Demaille <akim@epita.fr>
11341 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11342 AC_LIBSOURCE, AC_CONFIG_FILES.
11343 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11344 program version string doesn't match the package's.
11345 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11346 after `(cached)'.

11350 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11351 Allow expression to return any value that can fit into unsigned long
11352 (not int, as before). Check for output errors.
11354 2001-09-17 Bruno Haible <haible@ilog.fr>
11356 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11357 Always include <stdio.h> and <stdlib.h>. Evaluate
11358 the expression in an extra function before these includes. Call
11359 fprintf "%d" only after ensuring the argument is of type 'int'.
11360 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11362 2001-09-17 Paul Eggert <eggert@twinsun.com>
11364 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11365 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11366 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11367 when they don't exist.
11369 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11370 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11371 need it.
11373 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11374 version with the version used by fileutils 4.1, except use
11375 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11376 we don't need it.
11378 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11380 2001-09-13 Akim Demaille <akim@epita.fr>
11382 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11383 _first_.
11384 Reported by Gerrit P. Haase.
11386 2001-09-13 Akim Demaille <akim@epita.fr>
11388 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

11412 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
11414 2001-09-13 Akim Demaille <akim@epita.fr>
11416 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
11418 2001-09-13 Akim Demaille <akim@epita.fr>
11420 * lib/autotest/general.m4 (AT_INIT): Create and remove
11421 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11422 test suites can cohabit.
11424 2001-09-13 Akim Demaille <akim@epita.fr>
11426 * tests/mktests.sh: Don't output banners for empty test files.
11428 2001-09-13 Akim Demaille <akim@epita.fr>
11430 Test suites can be run independently of configure.

11468 (AT_SETUP): Reset AT_line, AT_keywords, AT_description.

11471 * lib/m4sugar/m4sugar.m4 (m4_append): Support a separator.
11472 (m4_list_append): Remove.
11474 Spread a few keywords in the Autoconf test suite.
11476 2001-09-10 Akim Demaille <akim@epita.fr>
11478 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

11494 2001-09-07 Akim Demaille <akim@epita.fr>
11496 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
11497 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
11498 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
11499 related variables into `at_package_*'.

11511 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
11512 in addition, it introduces useless differences in logs.
11513 (AT_INIT): Let atconfig and atlocal be both optional.
11514 Adjust PATH computation.
11515 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

11522 2001-09-05 Akim Demaille <akim@epita.fr>
11524 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'
11525 to avoid GCC warnings.
11526 From Uwe Seimet.
11528 2001-09-05 Akim Demaille <akim@epita.fr>
11530 * bin/autom4te.in: --language is -l, not -s.
11532 2001-09-05 Akim Demaille <akim@epita.fr>
11534 Be ready to handle filenames as stupid as `dnl.at', for if even
11535 the maintainer is dumb enough to do that...
11537 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11538 excellence in M4 quotation: consider `__file__' is active.

11571 New, extracted from main.
11572 Use IO::File wherever possible.
11573 (input.m4): Be constant, use -I instead of hard coding $tmp.

11575 Don't invoke `_au_disable', since ac was not loaded, but just
11576 `unm4.m4'.
11578 2001-08-31 Akim Demaille <akim@epita.fr>
11580 Version 2.52d.
11582 2001-08-31 Akim Demaille <akim@epita.fr>
11584 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
11585 previous patch.
11586 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
11588 2001-08-31 Akim Demaille <akim@epita.fr>
11590 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
11591 serious problems handling heredocs in heredocs.
11592 Reported by Nicolas Joly.
11594 2001-08-31 Akim Demaille <akim@epita.fr>
11596 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
11597 (Making testsuite Scripts): Update.
11599 2001-08-31 Akim Demaille <akim@epita.fr>
11601 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11603 2001-08-31 Akim Demaille <akim@epita.fr>
11605 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11606 (testsuite Scripts): There is no such thing as `atconfig.in'.
11607 And actually one diagram is missing: test suite runtime.
11609 2001-08-31 Akim Demaille <akim@epita.fr>
11611 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11612 inverse order.
11614 2001-08-31 Akim Demaille <akim@epita.fr>
11616 * bin/autoupdate.in (@include): `installcheck' revealed the path
11617 to m4sugar was lacking!
11619 2001-08-31 Akim Demaille <akim@epita.fr>
11621 * man/Makefile.am (.x.1): We really have to pass
11622 autom4te_perllibdir.
11624 2001-08-31 Akim Demaille <akim@epita.fr>
11626 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11627 debug scripts, in particular passing explicitly listed tests to
11628 run is stupid.
11630 2001-08-31 Akim Demaille <akim@epita.fr>
11632 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11633 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11634 Use directly autom4te, not autoconf.
11635 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
11637 2001-08-31 Akim Demaille <akim@epita.fr>
11639 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
11640 * bin/autoheader.in (%symbol): Strip arguments of macros.
11642 2001-08-31 Akim Demaille <akim@epita.fr>
11644 * doc/autoconf.texi: Catch up -I, --include changes.
11646 2001-08-31 Akim Demaille <akim@epita.fr>
11648 * bin/autom4te.in (&parse_args): Die on unknown languages.
11649 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
11650 need for autoconf.
11651 Promote --include over --macrodir and other obsolete options.
11653 2001-08-31 Akim Demaille <akim@epita.fr>
11655 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
11656 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
11657 * bin/autom4te.in ($autoconf): Pass --force.
11658 `print $out' doesn't print `$_' but `$out'.
11659 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11660 (autoheader): Pass --force since the test suite goes too fast for
11661 the time stamps.
11662 Adjust to the new autoheader messages.
11664 2001-08-31 Akim Demaille <akim@epita.fr>
11666 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11667 Check the completeness of the #template.
11668 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
11669 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
11670 invocation.
11672 2001-08-31 Akim Demaille <akim@epita.fr>
11674 * lib/Autom4te/General.pm (&find_file, &update_file): New.
11675 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11676 Drop AC_MACRODIR dead for real.
11677 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11678 `autoheader: `config.hin' is created'.
11679 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11681 2001-08-31 Akim Demaille <akim@epita.fr>
11683 * bin/autoheader.in: Rewrite in Perl.
11684 * tests/autoheader: Adjust.
11686 2001-08-31 Akim Demaille <akim@epita.fr>
11688 * bin/autoconf.in (--include, -I): New option.
11689 Map --localdir, --autoconf-dir onto it.
11690 Forward autom4te's options instead of interpreting them.
11691 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11692 There is no such envvar since the inception of autom4te.cfg.
11693 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11694 * bin/autoupdate.in: Adjust, and perform more control.
11695 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11696 * tests/autoconf: Dittowise.
11698 2001-08-31 Akim Demaille <akim@epita.fr>
11700 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11701 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11702 optionally `FILE'.
11703 Use -e, not -f, since /dev/null for instance is OK.
11704 (&parse_args): Adjust.
11705 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11707 2001-08-31 Akim Demaille <akim@epita.fr>
11709 * configure.ac: Also find tested executables in bin.
11710 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11711 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11712 installed peer executables, only PATH is allowed to resolve it.
11713 Pass `autoconf_dir' via options, not via invisible envvars.
11714 * lib/Autom4te/General.pm (&find_peer): Remove.
11715 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11716 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11717 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11718 find the executables for it.
11719 * tests/Makefile.am: Major cleanup. Too lazy to document...
11720 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11721 We only need PERL.
11722 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11723 indeed related to running the test suite, while passing
11724 --autoconf-dir and others is related to running non installed
11725 Autoconf executables. So don't do that, leave it to...
11726 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11727 * tests/autoscan: New.
11728 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11729 refer to library files: rely on --language.
11731 2001-08-29 Akim Demaille <akim@epita.fr>
11733 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11734 s/--set/--language/.
11736 2001-08-29 Akim Demaille <akim@epita.fr>
11738 * doc/autoconf.texi: Strip the @nodes.
11739 Suggested by Paul Eggert.
11740 (Initializing configure): Typo.
11742 2001-08-29 Akim Demaille <akim@epita.fr>
11744 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11745 Suggested by Paul Eggert.
11747 2001-08-29 Akim Demaille <akim@epita.fr>
11749 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11750 download in a tmp dir.
11752 2001-08-29 Akim Demaille <akim@epita.fr>
11754 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11755 case insensitive OSes out there :(
11756 From Tim Van Holder.
11758 2001-08-29 Akim Demaille <akim@epita.fr>
11760 * lib/autom4te.in: New.
11761 * lib/Makefile.am (edit, autom4te.cfg): New.
11762 * bin/autom4te.in (BEGIN): Simplify.
11763 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
11764 (&load_configuration): New. Use it.
11765 (&parse_args): Support --mode, --set, and --melt.
11766 * bin/autoconf.in: Simplify and adjust.
11767 * tests/Makefile.am (AUTOMAKE): Use --set.
11768 * tests/atlocal.in: Adjust.
11769 * BUGS: distcheck and check are weak.
11771 2001-08-29 Akim Demaille <akim@epita.fr>
11773 * lib/autotest/general.m4: Use
11774 foo=`(command) 2>/dev/null`
11775 not
11776 foo=`command` 2>/dev/null
11777 (at-devnull): Rename as...
11778 (AT-devnull): this.
11779 (--clean): Remove AT-* files too.
11780 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11781 Reported by Nicolas Joly.
11783 2001-08-28 Akim Demaille <akim@epita.fr>
11785 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
11786 quotes inside single quotes.
11787 Reported by Nicolas Joly.
11789 2001-08-28 Kevin Ryde <user42@zip.com.au>
11791 * doc/autoconf.texi (Function Portability): Mention C right shifts.
11793 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
11795 * lib/autotest/general.m4: Reword some messages.
11796 (AT_INIT): Check for the `times' builtin before using it.
11797 Support test ranges as arguments to the testsuite.
11798 Have -e imply -d as the help text suggested.
11800 2001-08-27 Akim Demaille <akim@epita.fr>
11802 * Makefile.maint: Formatting changes.
11803 (do-po-update, po-update, cvs-update, update): New targets.

11815 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11816 Support `VAR=VAL' as arguments.
11817 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
11818 may be set via the command line.
11820 2001-08-27 Akim Demaille <akim@epita.fr>
11822 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
11823 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
11824 first the build dirs, then the src dirs.

11827 2001-08-27 Akim Demaille <akim@epita.fr>
11829 * lib/autotest/general.m4 (AT_INIT): Output the definition of
11830 at_data_files earlier.

11834 2001-08-27 Akim Demaille <akim@epita.fr>
11836 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11837 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11838 readable.
11839 Adjust callers.
11840 * doc/autoconf.texi (Configuration Actions): Document the vars
11841 available in commands.
11842 Emphasize the risks of collisions in init-cmds.

11847 (Initializing configure): this new node.
11849 2001-08-27 Akim Demaille <akim@epita.fr>

11870 2001-08-27 Akim Demaille <akim@epita.fr>
11872 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
11873 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
11874 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11875 -> ac_dir).
11876 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11877 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11879 2001-08-27 Akim Demaille <akim@epita.fr>

11905 (AMTAR): Help automake define it.

11909 * m4/strip.m4: New.

11924 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11925 the name of the directory they're in, instead of the filename,
11926 since version.m4 is now in m4sugar, but m4_acversion must not be
11927 classified as an Autoconf macro.
11928 ($input_m4): Don't qualify the path to m4sugar.
11929 Rather, pass autoconf_dir to m4.
11930 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
11931 * tests/suite.at: Require 2.52c.
11933 2001-08-27 Akim Demaille <akim@epita.fr>

11945 of config.log on traps.
11946 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
11947 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
11948 for config.status'.
11949 Open the log as soon as possible.
11950 Use the same log introduction as configure's.
11952 2001-08-22 Paul Eggert <eggert@twinsun.com>
11954 * doc/autoconf.texi (Indices): New node.
11955 Move indices out of the top level menu and into this submenu.
11957 2001-08-22 Akim Demaille <akim@epita.fr>
11959 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11960 AC_TRY_COMMAND.

12004 can be used.
12006 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
12008 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile

12012 2001-08-20 Akim Demaille <akim@epita.fr>
12014 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
12015 * NEWS, README, README-alpha, TODO, tests/README: This package is
12016 `Autoconf', not `autoconf' (the executable).
12018 2001-08-20 Akim Demaille <akim@epita.fr>
12020 Info readers seem to need `Index' in the index node title :(
12022 * doc/autoconf.texi: Reverse the 2001-08-15 change which
12023 simplified index node names.
12025 2001-08-20 Akim Demaille <akim@epita.fr>

12067 2001-08-20 Akim Demaille <akim@epita.fr>
12069 Huh!?!?! There are still some user EOF tags used, which prevents
12070 their use in AC_CONFIG_COMMANDS for instance...
12072 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
12073 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

12134 2001-08-17 Akim Demaille <akim@epita.fr>
12136 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
12137 `$0.log' as for projects where testsuite is in src, we'd have
12138 testsuite.log created in src.

12142 * bin/autom4te.in (&parse_args): Recognize --normalize.

12152 2001-08-17 Akim Demaille <akim@epita.fr>
12154 * doc/autoconf.texi: Work around Texinfo buglets.
12155 (Transformation Rules): One example is enough, users are expected
12156 to have their brains on. And BTW, use DESTDIR.
12157 (dvar): New macro. Use it.
12159 2001-08-17 Akim Demaille <akim@epita.fr>
12161 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

12163 looking for ChangeLogs.
12165 2001-08-17 Akim Demaille <akim@epita.fr>
12167 * bin/autom4te.in: --normalize is a new option.
12168 * bin/autoconf.in: Use it.
12170 2001-08-17 Akim Demaille <akim@epita.fr>
12172 * bin/Makefile.am, lib/Autom4te/Makefile.am, lib/autoconf/Makefile.am

12175 2001-08-16 Paul Eggert <eggert@twinsun.com>
12177 * doc/autoconf.texi, doc/install.texi: Put copyright notice at

12180 2001-08-15 Akim Demaille <akim@epita.fr>
12182 * doc/Makefile.am (fu): New index, can't use fn because of defmac.
12183 Use it.
12185 2001-08-15 Akim Demaille <akim@epita.fr>
12187 * doc/autoconf.texi (pr): New index.
12188 (prindex, findex): Use, merge, and output them.

12194 * doc/install.texi: Use @command.
12195 (Environment Variables): Rename as...
12196 (Defining Variables): this.
12198 2001-08-15 Akim Demaille <akim@epita.fr>
12200 * doc/autoconf.texi (Function Portability): sprintf's return
12201 value.
12202 From Kevin Ryde.
12204 2001-08-15 Akim Demaille <akim@epita.fr>
12206 * Makefile.maint (CVS): New.
12207 (local-check): Run changelog-check. last.
12208 (alpha): Don't depend upon local-check, since...
12209 (cvs-dist): depends upon it.
12211 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
12213 * tests/Makefile.am: Use a clean-local rule to remove
12214 autom4te.cache (it's a directory, not a file.
12215 * Makefile.am: Ditto (but maintainer-clean-local).
12217 2001-08-15 Akim Demaille <akim@epita.fr>
12219 * bin/autom4te.in (@m4_warning): New.
12220 (&handle_m4): Use it.
12221 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12222 warnings are issued at each run.
12223 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12224 is in the src tree.
12226 2001-08-15 Akim Demaille <akim@epita.fr>
12228 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
12229 don't waste time running `autoupdate --version' works.
12230 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
12232 2001-08-13 Akim Demaille <akim@epita.fr>
12234 * doc/autoconf.texi (ma): Rename this index as...
12235 (ac): this.

12248 duration of the test suite.
12250 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
12252 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
12253 endianness for comparison instead of relying on AT_CHECK_ENV.
12255 2001-08-11 Paul Eggert <eggert@twinsun.com>
12257 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
12258 to the INSTALL file.
12260 2001-08-11 Paul Eggert <eggert@twinsun.com>

12285 * tests/mktests.sh: Update year in copyright notice.
12287 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
12289 * tests/semantics.at (AC_C_BIGENDIAN): New test.
12291 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12293 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12294 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12295 * doc/autoconf.texi (C Compiler Characteristics): Update
12296 documentation for AC_C_BIGENDIAN.
12298 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12300 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12301 magic values from an object file when cross-compiling.
12302 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12304 2001-08-10 Akim Demaille <akim@epita.fr>
12306 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12307 effects.
12308 Suggested by Russ Allbery.
12310 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12312 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12313 current $prefix to the sub-configures.
12315 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12317 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12318 extension (needed on BeOS). Reported by Guido van Rossum.
12320 2001-08-09 Akim Demaille <akim@epita.fr>
12322 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12324 2001-08-07 Akim Demaille <akim@epita.fr>
12326 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12327 removed.
12328 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12329 No need to remove the files before and after the each test, before
12330 each test and at the end of the suite is enough.
12331 Display only the children `times', not the shell's.
12332 If the test failed or was skipped, at-times is not available.
12334 2001-08-07 Akim Demaille <akim@epita.fr>
12336 Always produce testsuite.log, including when there are no
12337 failures. This helps getting information on skipped tests, and
12338 duration of the tests. Err, implement the latter btw.
12340 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12341 Dump information on the first run of each test.
12342 (AT_CLEANUP): Create `at-times' containing the duration of the
12343 test group.
12345 2001-08-07 Akim Demaille <akim@epita.fr>
12347 The use of `dumpstat' revealed that `len' was used although it
12348 should not. m4_text_wrap was using it, but in the Autoconf world
12349 where it is legal. Hence (i) test M4sh in its own world, not
12350 Autoconf's, and (ii), ahem, fix the bug :)
12352 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12353 does not like `' instead of [].
12354 (AT_INIT): Forbid `^_?AT_'.
12355 And don't output such tokens.
12356 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12357 `script.as', and `autom4te.cache'.
12358 Remove `empty' and `macro' which are no longer used.
12359 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12360 * tests/m4sugar.at: Use it.
12361 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12363 2001-08-07 Akim Demaille <akim@epita.fr>
12365 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12367 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12369 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12371 2001-08-04 Akim Demaille <akim@epita.fr>
12373 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12374 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12375 AC_TRY_LINK.
12376 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12377 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12378 (AC_F77_MAIN): Likewise.
12380 2001-08-04 Akim Demaille <akim@epita.fr>
12382 Don't rely on M4sugar outputting the patterns in files, since we
12383 might process the output _without_ running m4, hence without these
12384 files.
12386 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12387 * bin/autom4te.in (@Request::includes): Remove, unused.
12388 (@Request::source): Rename as...
12389 (@Request::input): this.
12390 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12391 (&handle_output): Fetch the patterns from the traces.
12392 `$forbidden' and `$allowed' are constant: use m//o.
12393 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12394 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12396 2001-08-04 Akim Demaille <akim@epita.fr>
12398 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12399 autoconf', i.e., in addition to caching traces, cache the output.
12401 * bin/autom4te.in (Request::cache): Rename as...
12402 (Request::id): this.
12403 ($cache, $icache, $tcache, $ocache): New.
12404 (&handle_m4): Save M4 output in the cache instead of $tmp.
12405 (&handle_output): Adjust.
12406 (&up_to_date_p): Check that the output cache is up to date too.
12407 (top level): Run `&handle_m4' iff force or the cache is invalid.
12408 Run `&handle_output' if the output cache is more recent.
12410 2001-08-04 Akim Demaille <akim@epita.fr>
12412 * bin/autom4te.in ($force): New.
12413 (&parse_args, &print_usage): -f, --force is a new option.
12414 (&handle_output): CPP directives might have spaces after `#'.
12415 (&parse_args): The first file only can be frozen.
12417 2001-08-04 Akim Demaille <akim@epita.fr>
12419 Don't let autom4te compute the `include' traces several times:
12420 first check that the trace cache file is up to date, and then
12421 compare its timestamp with that of the output.
12423 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12424 the preamble. Don't require 5.005 as Autom4te::General does it,
12425 and better yet (use `use', not `require'!).
12426 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12427 Class::Struct as Autom4te::Struct.
12428 * lib/Autom4te/General.pm (File::stat): Use it.
12429 (&mtime): New, export it.
12430 * bin/autom4te.in: Use it.
12431 Declare `$req' is invalid if it is outdated.
12432 Don't declare it valid before saving it if something went wrong.
12434 2001-08-04 Akim Demaille <akim@epita.fr>
12436 Autom4te shall not encode Autoconf data, and preselecting traces
12437 must be proposed to the users.
12439 * bin/autom4te.in (@required_trace): Remove.
12440 (@preselect): New.
12441 (&parse_args, &print_usage): -p, --preselect is a new option.
12442 (&up_to_date_p): Adjust.
12443 * bin/autoconf.in: Preselect some Autoconf macros.
12445 2001-08-04 Akim Demaille <akim@epita.fr>
12447 * tests/tools.at (autoconf --trace: user macros): Check traces on
12448 macros invoked without arguments, and macros invoked with multiple
12449 lines arguments.
12451 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
12453 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
12454 arguments.
12456 2001-08-03 Akim Demaille <akim@epita.fr>
12458 * bin/autoconf.in ($@): Work around the usual sh bug.
12459 From Nicolas Joly.
12461 2001-08-03 Akim Demaille <akim@epita.fr>
12463 Clean up the handling of the M4 builtins tracing exception.
12465 * bin/autom4te.in (Request::request): Don't complete M4 builtins
12466 trace requests.
12467 (@m4_builtins): Rename as...
12468 (@m4_builtin): this.
12469 (%m4_builtin_alternate_name): New.
12470 (&parse_args): Complete the trace requests with alternate names.
