12 * doc/autoconf.texi: Direntry for "autoconf Invocation"
13 renamed to "autoconf-invocation"
15 * doc/autoconf.texi (Caching Results): The CACHE-ID variable
16 in the examples should not use the internal "ac_" prefix.
18 2007-05-05 Noah Misch <noah@cs.caltech.edu>
20 * lib/autotest/general.m4 (_AT_NORMALIZE_TEST_GROUP_NUMBER): Use `eval'.

30 * lib/autoconf/lang.m4, lib/autoconf/c.m4,
31 lib/autoconf/fortran.m4, lib/autoconf/erlang.m4: Cleanup of
32 section titles and other comments; no code change.
34 2007-05-01 Kevin Ryde <user42@zip.com.au>
36 * doc/autoconf.texi (Particular Programs): Typo
37 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
39 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
41 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
42 'configure' will fail if the shell lacks proper support for shell
43 functions. Suggested by RMS.
45 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
47 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
48 about Solaris /bin/printf '%010000x' 123. Problem reported by
49 Bruno Haible.
51 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
53 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
54 for a.* when searching for executables, as this prevents users
55 from having files like a.c. Problem reported by Ralf Wildenhues in:
56 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
57 This fixes a problem introduced on 2000-12-19.
59 2007-04-26 Paul Eggert <eggert@cs.ucla.edu>
61 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
62 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
63 via Bruno Haible.
65 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
67 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
68 AC_CHECK_TYPE, AC_CHECK_TYPES.
69 * doc/autoconf.texi (Generic types): C types must be type-names
70 (the C terminology), not type-ids (the C++ term). C++ types
71 must not be anonymous.
72 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
73 for C++; this drops support for anonymous struct and union types,
74 which were problematic anyway.
75 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
76 for C++.
78 2007-04-12 Jim Meyering <jim@meyering.net>

91 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
92 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
93 with objects too. Document the restrictions on its use.
94 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
95 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
96 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
97 works but the latter doesn't, then it's a valid type.
98 This lets people use function types and so forth.
99 For C++ there doesn't seem to be a simple solution, so leave it alone.
100 (AC_CHECK_SIZEOF): Allow argument to be a variable.
101 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
102 AC_CHECK_TYPE; that wasn't documented or necessary.
104 2007-04-11 Stepan Kasal <kasal@ucw.cz>
106 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
107 when cross-compiling.

119 2007-04-06 Paul Eggert <eggert@cs.ucla.edu>
121 * doc/autoconf.texi (Particular Types): AC_C_LONG_DOUBLE is now
122 obsolescent. Suggested by Bruno Haible.
123 * NEWS: Document this.
125 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
127 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
128 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
129 default still has the problem. Problem reported by Bruce Korb.
131 2007-03-28 Stepan Kasal <kasal@ucw.cz>
132 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

149 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
150 checks for unsigned long long int.
152 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
154 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
155 nonstandard grep R.E. escape sequences.
157 2007-03-17 Jim Meyering <jim@meyering.net>
159 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
160 (Limitations of Usual Tools): Also list \< and \>, and mention that
161 HP-UX's grep, like the one from Solaris, does not support that syntax.
163 2007-03-09 Stepan Kasal <kasal@ucw.cz>
165 * doc/autoconf.texi (Specifying Names): `--host' does not
166 change the build type.
168 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
170 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
171 suggests AC_CONFIG_HEADERS.
172 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using

182 universal binaries. Problem reported by Elias Pipping.
184 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
186 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
187 * doc/autoconf.texi (C Compiler): Document this. There is a new
188 extra argument ACTION-IF-UNIVERSAL.
189 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
190 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
191 Reindent for sanity's sake.
193 2007-02-24 Eric Blake <ebb9@byu.net>

203 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
204 status of rm so we know when it failed.
205 If cleaning of test dir failed before running the test, warn.
206 Output the line separator in verbose mode before the warning
207 to make clear the warning belongs to the following test.
209 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

218 errors introduced in last change.
220 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
222 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
223 an actual carriage return. Use "ac_cr" to contain the actual
224 carriage return.
225 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
226 with traditional Awk and begin.
227 * tests/torture.at (Limitations of Builtins): Document the problem

257 2007-01-31 Eric Blake <ebb9@byu.net>
259 * THANKS (people): Update.
261 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
263 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
264 latest version.
265 (Shell Substitutions): Note problems with @{var:=value} etc.
266 Add a new section for problems with @{#var} etc. Problem noted
267 by Ralf Wildenhues. See:

270 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
272 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
273 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
274 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
275 substitution will still be done by the special code.
276 Report by Jim Meyering.
278 * doc/autoconf.texi (File System Conventions): Mention that
279 $PATH_SEPARATOR is for the build system only.

289 * tests/torture.at (Substitute and define special characters):
290 Test all 8 bit non-NUL characters.
291 Report against Automake by Patrick Welche.
293 2007-01-15 Stepan Kasal <kasal@ucw.cz>
295 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
297 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
299 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
300 early on the reader side, drop stderr of the input to avoid
301 `broken pipe' error output; this may happen even with shell
302 builtin `echo' of some bash versions. Reports by Ian Macdonald
303 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
305 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
307 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
308 separate items of `ac_user_opts', to avoid long lines.
309 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.

317 Fix some wording problems noted by Paolo Bonzini in:
318 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
319 * doc/autoconf.texi (Signed Overflow Examples): Give more
320 discussion about the allow_superuser_privileges example,
321 and change it a bit to make things clearer.
322 (Optimization and Wraparound): Clarify whether the compiler
323 will generate an infinite loop for the example derived from
324 Autoconf's mktime test.
325 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
326 Also, clarify unsigned multiplication overflow.
328 2007-01-04 Eric Blake <ebb9@byu.net>
330 * bin/Makefile.am (RELEASE_YEAR): New macro.
331 (edit): Use it to supply correct copyright year to scripts.
332 * bin/autoconf.as (version): Use it.
333 * bin/autoheader.in ($version): Likewise.
334 * bin/autom4te.in ($version): Likewise.
335 * bin/autoreconf.in ($version): Likewise.
336 * bin/autoscan.in ($version): Likewise.
337 * bin/autoupdate.in ($version): Likewise.
338 * bin/ifnames.in ($version): Likewise.
340 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
342 * doc/autoconf.texi (Integer Overflow): Revised based on today's
343 feedback. The most important changes document what happens when
344 you convert an out-of-range value to a signed integer type, and
345 say that (sum < a) != (b < 0) reliably detects overflow when sum =
346 a + b.
348 * doc/autoconf.texi (Integer Overflow): Greatly expand and
349 rewrite, taking notions from the recent discussion on the gcc and
350 autoconf mailing lists; please see
351 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
352 and follow the many links.
353 (Integer Overflow Basics, Signed Overflow Examples):
354 (Optimization and Wraparound, Signed Overflow Advice):
355 (Signed Integer Division): New sections.
357 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
359 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
360 preprocessor macro arguments in traced name.
361 * doc/autoconf.texi (Defining symbols): Document longstanding
362 support for AC_DEFINE-ing macros with arguments, and document
363 behavior when the same variable has multiple AC_DEFINEs.
364 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
365 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
366 macros directly, giving much shorter and simpler code.
368 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
370 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
371 space before "$ac_configure_args" to prevent a 'config.status
372 --recheck' failure if ac_configure_args doesn't contain a leading
373 space. This works around a problem with the XEmacs configure.ac,
374 which uses the (undocumented) ac_configure_args variable
375 inconsistently with Autoconf.
377 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
379 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
380 Include <limits.h>, and use its INT_MAX to rewrite the
381 j loop so that it does not overflow 'int'. Problem reported by
382 Ralf Wildenhues in
383 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
384 Play it safe by shifting left by 1 rather than multiplying by 2,
385 as GCC is less likely to optimize this away when the value
386 is signed (when it assumes overflow leads to undefined behavior).
387 Also, don't assume time_t uses two's complement.
389 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
391 * tests/torture.at (Substitute a 2000-byte string): Avoid using
392 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
393 dumps core on it. Report by Tim Rice.
395 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
397 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
398 --disable-option-checking to --help output even when
399 AC_PRESERVE_HELP_ORDER is not used.
400 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
401 --with argument, rather than argument with [-.] replaced by
402 underscores.
403 * NEWS: Fix typo in previous change; the news was in the
404 wrong section.
406 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
408 * NEWS: Warnings are now generated by default for unknown
409 --enable-* and --with-* options.

413 Checking, and use this to shorten our section.
414 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
415 "$x" to test "x$foo" != x.
416 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
417 Don't warn if $enable_option_checking is "no".
418 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
419 ac_unrecognized_opts to the empty string.
420 Don't echo the unrecognized opts, as this might mishandle
421 backslashes or leading -.
422 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
423 usage next to the other --disable-FEATURE options in the
424 help string.
426 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
428 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
429 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
430 Print warning for unrecognized --with and --enable options
431 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
432 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
433 Disable option checking when subdirs are configured.
434 (AC_OUTPUT): If warnings are enabled, print warning about
435 unrecognized --with and --enable options at the end of
436 the configure output (as well as at the beginning).
437 * doc/autoconf.texi (Option Checking): New node.
438 Document new option warning functionality.

447 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
448 Define HAVE_GETMNTENT to 1, not to the empty string.
449 Problem originally reported by Jochen Friedrich in
450 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
452 This change prompted by a problem report by Andrey Simonenko in
453 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
454 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
455 object-like macros only, in the traditional portable character
456 set.
457 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
458 Warn about attempts to define things that are not identifiers.
459 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
460 awful hack that AC_DEFINEd macro names containing parentheses.
462 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
464 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
465 too drastic, even if Texinfo in theory requires it for info mode.
467 (config.status Invocation): Renamed back from Recreating a
468 Configuration).
469 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
470 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.

479 * NEWS: Document changes with echo and printf, and the lack
480 of limits on the total size of multi-line values of substituted
481 variables, and the AC_FUNC_FSEEKO fix.
483 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
485 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
486 Writing configure.ac.
487 (Autoconf Input Layout): Renamed from configure.ac Layout.
488 (Recreating a Configuration): Renamed from config.status Invocation.
489 (Obsolete Recreation): Renamed from Obsolete config.status Use.

493 (Autom4te Cache): Renamed from autom4te.cache.
495 * BUGS: Remove mention of VPATH problem, since it's now documented
496 not to be a bug in the Autoconf build procedure itself, but rather
497 a problem with the proprietary `make' programs.
499 * doc/autoconf.texi (Build Directories): Add a cross reference
500 to VPATH and Make.
502 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
503 * doc/standards.texi: Sync from gnulib.
505 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
506 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
507 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
508 generated automatically.
510 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
512 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
513 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
514 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
516 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
518 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
519 `CEOF$ac_eof' special marker, the awk script cannot contain a
520 line matching `^CEOF', so this is not needed any more.
521 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
522 special marker in the test.
524 2006-12-06 Stepan Kasal <kasal@ucw.cz>
526 * tests/tools.at (autom4te preselections): Use `find -newer';
527 remove one of the sleeps.
529 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
530 more readable, using ...
531 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
533 * doc/autoconf.texi (autoheader Invocation): Do not double-
534 quote the parameter of `AH_BOTTOM' in the example.
536 2006-12-05 Stepan Kasal <kasal@ucw.cz>
538 * doc/autoconf.texi (Configuration Headers): Remove the
539 example with multiple input files.
540 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
541 multiple input files.
543 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
545 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
546 creating the awk substitution script, handle one input line at a
547 time, so that the maximum length of a substituted (multi-line)
548 value is not limited by the size of the sed pattern space.
549 The trade-off is a slightly repetitive sed script.
550 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
551 can only have up to 7 characters, due to Solaris 10 /bin/sed.
552 * tests/torture.at (Substitute a 2000-byte string): Increase the
553 test with several long lines, they should not be caught by sed
554 limits any more.
556 * tests/tools.at (autom4te preselections): New test, to flag
557 entries missing from autom4te.cfg.
558 Report by David Byron <dbyron@hheld.com>.
560 * tests/torture.at (Substitute a 2000-byte string): Actually use
561 AC_PROG_AWK, so the last change works as intended.
562 (Substitute and define special characters): Likewise.
563 (Substitute a newline): Likewise.
565 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
566 instead of `awk' consistently.
567 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
568 * tests/torture.at (Torturing config.status): Test both the
569 result of AC_PROG_AWK and plain awk.
570 (Substitute a 2000-byte string): Likewise.
571 (Substitute and define special characters): Likewise.
572 (Substitute a newline): Likewise.
574 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
576 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
577 can be assigned to a function pointer. Problem reported by
578 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
579 part of a patch by Ralf Wildenhues in that same bug report.
581 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
583 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
584 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
586 2006-12-01 Eric Blake <ebb9@byu.net>
588 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
589 cross-compiling from cygwin to mingw.
590 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
591 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
592 to lib/autoconf/c.m4.
594 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
596 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
597 string for more reliable failure. Wrap the entire test that
598 causes the broken Solaris printf to dump core, in a subshell,
599 so the segmentation fault message is reliably suppressed.
600 Fix shell expansion errors by using /usr/ucb/echo always;
601 avoid an error on systems without it by another subshell.
602 Avoid m4 expansion of `$1'. Set the zeroth argument of the
603 subshell-$as_echo to `as_echo', for better error message.
605 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
607 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
608 `BASH_SOURCE' contain a newline, set them to empty, as they may
609 not be unset.
611 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
613 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
614 years and is too hard to maintain now. The last straw was
615 reported by Jerker Baeck in
616 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
617 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
618 * doc/autoconf.texi (Particular Functions): Move
619 AC_FUNC_SETVBUF_REVERSED from here...
620 (Obsolete Macros): ... to here. Say that it does nothing now.
621 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
622 Turn into (almost) a no-op.
624 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
625 (AC_C_VOLATILE):
626 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
627 These macros are obsolescent and new applications shouldn't need them.
628 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
629 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
630 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
631 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
632 (AC_FUNC_VPRINTF): Likewise.
633 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
634 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
635 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
637 * doc/autoconf.texi (Setting Output Variables): Mention that
638 @VAR1@VAR2 has unspecified behavior. Problem reported by
639 Ralf Wildenhues.
640 * NEWS: Mention this.
642 * Makefile.am: Put only a single '#' into the copyright notice,
643 so that it's also present in the output file. Standardize wording
644 in makefile copyright notices to match GNU coding standards.
645 * bin/Makefile.am: Likewise.
646 * doc/Makefile.am: Likewise.
647 * lib/Makefile.am: Likewise.
648 * lib/freeze.mk: Likewise.
649 * lib/autoconf/Makefile.am: Likewise.
650 * lib/autoscan/Makefile.am: Likewise.
651 * lib/autotest/Makefile.am: Likewise.
652 * lib/m4sugar/Makefile.am: Likewise.
653 * man/Makefile.am: Likewise.
654 * tests/Makefile.am: Likewise.
655 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
656 one-line file.
658 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
660 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
661 in the sed script that mangles the awk script: delete up to the
662 first exclamation mark only.
663 * tests/torture.at (Substitute and define special characters):
664 Test '!' too.
666 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
668 Rewrite config files generation: avoid quadratic growth in
669 the number of substituted variables by using awk instead of sed
670 for the bulk of the substitutions.
671 * NEWS: Mention this.
672 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
673 forbidden in the output (and thus input) file.
674 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
675 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
676 generate just one large awk script for substitutions,
677 eliminating much of the earlier complexity, while adding some
678 new complexity. Only expand the substitution templates at
679 configure time, for smaller configure script size. If
680 _AC_SUBST_FILES are used, test 'awk' for working getline support
681 at config.status time. If absent, interpolate through the
682 shell. The awk script was written with much help
683 from Paolo Bonzini and Paul Eggert.
684 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
685 (_AC_SED_FRAG_NUM): Likewise.
686 (_AC_SUBST_CMDS): Renamed from...
687 (_AC_SED_CMDS): ...this.
688 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
689 * tests/torture.at (Substitute a 2000-byte string): Also
690 substitute a line with 1000 words, and a variable with several
691 long lines.
692 (Substitute and define special characters): Test awk special
693 characters, and put substitution input strings `@foo@' in the
694 output, to test that no recursion happens; test several other
695 combinations from Paolo Bonzini.
697 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
699 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
700 that replaced echo with AS_ECHO where this wasn't necessary.
701 Problem reportd by Ralf Wildenhues.
702 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
703 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
704 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
706 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
708 * lib/freeze.mk (GREP): Removed, no need to initialize this.
710 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
712 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
713 that traditional Awk lacks 3-arg "split". It has it.
714 Mention that FS must be a single character, and a few other
715 99-byte limits of traditional Awk.
716 Mention that if (i in a) doesn't work with traditional Awk.
718 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
720 * tests/autotest.at (BSx641-newline in command):
721 (BS-BS-newline in command, BSx640-newline in command):
722 (Newline-CODE-BS-newline in command):
723 (Single-quote-BS-newline in command):
724 (Single-quote-newline-BS-newline in command):
725 Use printf '%s\n' instead of echo, for portability to hosts
726 where echo interprets backslashes. This will break on hosts
727 that lack printf, but for now let's assume all such hosts
728 are dead (if not, we should get reports of test failures).
730 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
732 'echo' has some portability problems, when given a first argument
733 with a leading '-', or when given any argument containing '\'.
734 Avoid using 'echo' in these cases.
735 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
736 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
737 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
738 * lib/autotest/general.m4 (AT_INIT): Likewise.
739 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
740 argument might be unportable.
741 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
742 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
743 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
744 (_AC_FC_LIBRARY_LDFLAGS): Likewise.

746 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
747 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
748 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
749 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
750 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
751 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):

755 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
756 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
757 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
758 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
759 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
760 * bin/autoconf.as: Redo verbose flag implementation, as the old
761 scheme wouldn't work with AS_ECHO.
762 * lib/autotest/general.m4 (AT_INIT): Likewise.
763 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
764 Don't use ECHO_T, since ECHO_N is now reliable.
765 * lib/autotest/general.m4 (AT_INIT): Likewise.
766 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
767 rather than using a here-document to put the script into a file.
768 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
769 use AS_ECHO.
770 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
771 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
772 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
773 bug, but we might as well stop using ECHO_N and ECHO_C internally.
774 * lib/autotest/general.m4 (AT_SETUP): Likewise.
775 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
776 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
777 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
778 operand, as AS_ECHO requires. Avoid double file name expansion.
779 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
780 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
781 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
782 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
783 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
784 Double-quote strings that would otherwise contain M4 comments.
785 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
787 * configure.ac (AC_INIT): Bump to 2.61a.
788 * NEWS: Likewise.
790 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
792 Version 2.61.
794 * configure.ac (AC_INIT): Bump to 2.61.
795 * NEWS: Likewise.
797 * tests/autotest.at (Macro with backslash in a test title):
798 Comment out for now, as this tests neither fails nor passes
799 reliably. Problem reported by Ralf Wildenhues.
801 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
803 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
804 in previous change, which caused test failures.
806 2006-11-16 Stepan Kasal <kasal@ucw.cz>
808 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
809 code for --enable, --disable, --with, and --without to...
810 (_AC_INIT_PARSE_ENABLE): ... a new macro.
811 * doc/autoconf.texi (Package Options):
812 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
814 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
816 Import these changes from config via gnulib:

841 Import this change from gnustandards via gnulib:
843 2006-11-15 Karl Berry <karl@gnu.org>
845 * standards.texi: core -> memory, throughout.
846 (CPU Portability): show correct example of calling write
847 on a char value; thanks to Paul Eggert for the code.
848 Both of these suggestions from Eugene Y. Vasserman.
851 Import these changes from texinfo via gnulib:
853 2006-11-08 Karl Berry <karl@gnu.org>

857 no further ado.
859 2006-11-05 Karl Berry <karl@gnu.org>
861 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

873 first argument may also contain dots.
875 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
877 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
878 benefit of platforms like Solaris+GCC where it is common to have a
879 non-working g++ installation.
881 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

887 ./micro-suite.
889 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
891 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
892 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
893 Imported from a similar patch to gnulib by Bruno Haible.
895 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
897 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
898 * doc/autoconf.texi (C Compiler): Document them.
899 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
900 New macros, taken from gnulib.
902 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>
904 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in
905 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
906 Matthew Woehlke.
908 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
910 * tests/torture.at (Configuring subdirectories): Do not skip
911 Automake 1.10 nor future Automake 11.1 (sic).
913 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
914 and Stepan Kasal <kasal@ucw.cz>
916 Handle special characters in test case titles correctly.
917 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
918 properly.
919 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
920 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
921 argument. Extend to check titles printed by ./micro-suite and
922 ./micro-suite -l and the title in micro-suite.log.
923 (Backquote in a test title,
924 Single-quote in a test title,
925 Double-quote in a test title): Don't expect failure anymore.
926 (Backslash in a test title): Put a non-whitespace character after the
927 backslash so that Bourne shells might actually see it as an escape
928 sequence.
929 (Brackets in a test title,
930 Pound in a test title,
931 Comma in a test title,
932 Quoted Macro in a test title,

935 (Macro with backquote in a test title,
936 Macro with double-quote in a test title,
937 Macro with backslash in a test title): New tests expected to fail.
938 * tests/torture.at (#define header templates): M4-quote this title in
939 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
940 The visible effect was a stray [] in the testsuite output.
942 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
944 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
945 `trap ... 0' inside a function, for AIX sh.
947 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
949 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
950 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
951 5363) simply issues a warning when dividing by zero at compile
952 time. Problem reported by Elias Pipping.
954 2006-10-26 Eric Blake <ebb9@byu.net>
956 * THANKS: Update.
957 * doc/autoconf.texi (Evaluation Macros): Improve the example to
958 show effect on macros that expand with commas.
959 Reported by Joel E. Denny.
961 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
962 Also work with M4 1.4.8.
964 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
966 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
967 Jim Meyering.
969 2006-10-25 Stepan Kasal <kasal@ucw.cz>

983 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
985 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
986 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
987 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
988 reported by Nelson H. F. Beebe for Coreutils 6.4.
990 * tests/tools.at (autoconf --trace: user macros): Remove test
991 for tracing multiline macros, since m4 1.4.7a uses a different
992 way to number lines. Problem reported by Ralf Wildenhues.
994 2006-10-24 Stepan Kasal <kasal@ucw.cz>
996 * bin/autom4te.in (handle_m4): Do not redirect stdin to
997 /dev/null since the heuristics for interactive behaviour was
998 fixed in CVS m4.
1000 * bin/autom4te.in: With --force, always refresh the output
1001 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

1020 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
1021 AC_CACHE_CHECK_INT, since it's no longer public.
1022 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1023 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
1025 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1027 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
1029 2006-10-19 Eric Blake <ebb9@byu.net>

1051 2006-10-14 Stepan Kasal <kasal@ucw.cz>
1053 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
1054 looking for special shell characters.
1055 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
1056 macro defined by AS_VAR_PUSHDEF before passing it as a
1057 parameter.
1058 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):

1068 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1070 (Imported from Automake.)
1071 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1072 which incorrectly sets the mode of an existing destination
1073 directory. In some cases the unpatched install-sh could do the
1074 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1075 system. We hope this is rare in practice, but it's clearly worth
1076 fixing. Problem reported by Alex Unleashed in
1077 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1078 Also, don't bother to check for -m bugs unless we're using -m;
1079 suggested by Stepan Kasal.
1081 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1083 Import this change from Automake:

1087 is enabled by default with gnu and gnits strictness.
1088 Report from Bruno Haible.
1090 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
1091 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
1092 gnu and gnits modes.
1094 Import this change from Config:
1096 2006-09-20 Ben Elliston <bje@gnu.org>

1099 Import this change from Gnulib:
1101 2006-09-16 Karl Berry <karl@gnu.org>
1102 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
1103 to avoid sectioning errors.
1105 Import these changes from Texinfo:
1107 2006-10-04 Karl Berry <karl@gnu.org>
1108 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
1109 (\quoteexpand): rename to \rquoteexpand.
1110 (\codequoteleft): new def, to look for @set codequotebacktick.
1111 (\lquoteexpand, \quoteexpand): new defs.
1112 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
1113 (\code): must use new \...Char values, since now ` is active.

1116 * build-aux/texinfo.tex (\textdegree): New command.
1118 2006-08-12 Karl Berry <karl@gnu.org>

1123 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
1125 2006-10-13 Stepan Kasal <kasal@ucw.cz>
1127 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1128 added to the template can get mangled.
1130 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1132 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1133 include the default headers, and redefine obstack_chunk_alloc
1134 and obstack_chunk_free. Fixes false failure with glibc.
1136 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1138 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
1139 for backward compatibility with Libtool 1.5.22. Problem reported
1140 by Ralf Wildenhues.
1142 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1144 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
1145 AC_PROG_CC.
1146 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
1148 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1150 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
1151 the NonStop platform.
1152 * doc/autoconf.texi (Posix Variants): Likewise.
1153 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1155 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1156 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1157 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1158 Use a better substitute, by inspecting the output of "ls"
1159 rather than just using ":".
1160 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1161 rather than AS_EXECUTABLE_P, since we needn't worry about
1162 non-regular files here.
1164 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1165 due to configuration hassles with this. See Tonya Underwood's report
1166 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1167 * doc/autoconf.texi (Special Shell Variables): Likewise.

1173 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
1175 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1177 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1178 initialization which is not inherited through the environment
1179 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1180 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1182 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1184 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1185 problems with mkdir -p -m.
1187 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1189 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1190 comment about ac_cpp_err; it was incorrect, and anyway
1191 ac_cpp_err is being removed below.
1192 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1193 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1194 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1195 nobody uses it.
1196 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1197 with werror_flag and conftest.err and so forth. This is more
1198 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1199 and anyway the user shouldn't normally want to see this gorp logged.
1200 Problem reported by Ralf Wildenhues.
1201 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1202 empty, not 'no', since the rest of the code uses 'test -z'.
1204 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1206 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1207 Use a single call to AC_DO_TOKENS rather than multiple, for
1208 efficiency.
1209 (_AC_LINK_IFELSE): Test that resulting file is executable.
1210 Problem reported by mwoehlke in
1211 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1213 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1214 than creating a file to use with test -x; this is much faster.
1216 2006-10-02 Bruno Haible <bruno@clisp.org>
1218 * lib/autom4te.in (Automake-preselections): Add
1219 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1221 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1223 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1224 standard error, `experr' should be used, not `expout'.
1226 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1228 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1229 fseeko testing program twice; just use the earlier result.
1230 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1231 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1232 still doesn't let the program compile.
1233 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1234 failed.
1236 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1237 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1238 include it, without including anything else.
1239 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1240 expressions.
1241 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1243 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1245 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1246 `error.h', and include it, for a `error_at_line' prototype.
1247 Use a nonempty format string in the link test.
1248 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1249 for a declaration of wait3.
1251 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1253 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1254 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1255 can apply to constants too, and that it checks for macro defns.
1256 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1257 and simply cast the identifier to void. This handles structure
1258 values. Problem reported by Ralf Wildenhues.
1259 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1261 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1263 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
1264 structure, and function symbols.
1266 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1268 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
1269 member.

1315 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
1316 --error-output, to avoid warnings with M4 2.0.
1318 2006-09-19 Stepan Kasal <kasal@ucw.cz>
1320 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

1331 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
1332 mistaken comment: the path has to be relative; do not use
1333 the path at runtime.
1335 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1337 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

1341 for both changes.
1342 * doc/autoconf.texi (Setting Output Variables): Fix example to

1345 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
1347 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
1348 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
1349 for the existence of the directory at configure-time. That's
1350 too late, anyway. Problem reported by Stefan Seefeld.
1352 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
1353 7.1.4 /usr/bin/posix/sh described by Tim Rice in
1354 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
1356 2006-09-11 Stepan Kasal <kasal@ucw.cz>
1358 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
1359 works with GNU M4 1.4.3 again; make the normalized form
1360 match the current m4 message; fix the description.
1361 * test/tools.at (autom4te cache): Adapt to the change.
1363 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
1365 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
1366 to catch glibc bug 2821
1367 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
1369 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1370 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1371 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
1372 assume C89.
1374 2006-09-08 Stepan Kasal <kasal@ucw.cz>
1376 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

1394 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1395 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1396 accept files with extension `.f'. For consistency, also prefer
1397 xlf over f77.
1398 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
1399 from last patch.

1414 before AC_PROG_FC, due to a bug in Autoconf.
1416 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
1418 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
1419 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
1420 except the first two arguments are reversed.
1421 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1422 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
1423 caches nor outputs a diagnostic. Suggested by Bruno Haible.
1424 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
1425 equivalent to the old AC_COMPUTE_INT.
1426 (AC_COMPUTE_INT): No longer caches or reports. New signature.
1427 All uses changed to AC_CACHE_CHECK_INT.
1428 * tests/base.at (AC_CACHE_CHECK_INT): New test.
1429 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
1431 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
1433 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
1434 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
1435 programs should use their Gnulib counterparts.
1436 * doc/autoconf.texi (Particular Functions): Likewise.
1437 (Macro Names, testsuite Invocation): Replace uses of these
1438 obsolete macros with uses of non-obsolete macros.

1462 simplify the code.
1464 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
1466 Fix Lex library problem reported to us by Julio Garvia.
1467 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
1468 for the default, which the user can override.
1469 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1470 deal with LEXLIB.
1471 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1472 didn't work if some values were cached but not others. Test for
1473 broken lex libraries like native ia64-hp-hpux11.22; see
1474 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1475 work around the problem by preferring an empty LEXLIB to -lfl or
1476 -ll. Let the user set LEXLIB='' to indicate no library needed.
1478 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1479 * README: Likewise.
1480 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

1581 * doc/autoconf.texi (Particular Programs): Mention that
1582 @INSTALL@ and @MKDIR_P@ may vary for different output files.
1583 Reported by Alexandre Duret-Lutz.
1585 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
1587 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore

1589 Bill Northcott in
1590 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.

1604 -Wundef -Werror". Problem reported by David Fang in
1605 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1606 * doc/autoconf.texi (Header Templates, Default Includes):
1607 (Particular Functions, Generic Functions, Header Portability):
1608 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
1609 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

1621 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1622 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1623 this.
1625 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1627 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1628 problems with arg script text that doesn't end in newline, and
1629 with '-e a...'. Problems reported by Ralf Wildenhues.
1631 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1633 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

1643 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1644 --help' should mention that `--version' outputs configuration
1645 settings. Report by Bruno Haible.
1647 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1649 Fix test suite failures reported by Pierre in

1665 less skeptical about "volatile", after discussion with
1666 Bruno Haible on bug-gnulib.
1667 (Limitations of Usual Tools): Warn about sed stripping
1668 leading white space from text. From Bruno Haible.
1670 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1672 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1673 compiler complains about it, even if things works after the
1674 complaint. Problem reported by Peter O'Gorman.
1676 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1677 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1678 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1680 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1682 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

1690 to match M4 1.4.5.
1692 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1694 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1695 under AC_C_VOLATILE.
1696 (Volatile Objects): Be a little less skeptical about what
1697 "volatile" means. Derived from thoughts by Ben Pfaff in
1698 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1700 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1702 * doc/autoconf.texi: Fix some typos.
1704 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1706 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1707 more globally, since the 2006-06-30 patch didn't suffice. Problem
1708 reported by Keith Marshall. Also, don't bother with builddir2,
1709 since it shouldn't be needed any more.
1711 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1713 * doc/autoconf.texi (Generic compiler characteristics):
1714 Document AC_COMPUTE_INT. Fix wrong statements on Default

1728 * NEWS: Document previous change.
1730 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1732 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1733 Require that long long int be at least 64 bits wide. C99 requires
1734 this and enough programs depend on it so we should check for it.
1735 Bruno Haible reports in
1736 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1737 that long long int is 32 bits wide with some nonstandard compilers.
1738 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1740 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1742 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1743 to a nonexistent file, so that we don't have to worry about
1744 a local site configuration that doesn't use /usr/local.
1745 Problem reported by Keith Marshall in
1746 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1748 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1750 * doc/autoconf.texi: Be more consistent about using @acronym with
1751 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1752 quite right (it talked about "OSF/Tru64", even though the
1753 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1754 and it even mentioned "OSF 4"!) and at this point there's little
1755 reason to talk about OSF any more, since it died in 1994.
1756 (Specific Compiler Characteristics): Simplify example of
1757 negative-size array.
1758 (File Descriptors): Reorder to make the text flow better.
1759 Remove joke about "appreciate the various levels"; I didn't get it.
1760 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1761 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1762 (File Descriptors, Limitations of Usual Tools):
1763 Tone down the advice against renaming or removing open files.
1764 (Limitations of Usual Tools): Add a new section, on 'rm'.
1766 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1768 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1769 -lXt in LIBS, idea from Karsten Hopp; this was due since
1770 this change:
1772 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1773 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1774 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1775 (which belong to Xt, not X itself). See Debian bug 327655.
1777 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1779 * configure.ac (AC_INIT): Bump to 2.60a.

1793 quadrigraph correctly in traces.
1795 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1796 Fix typos.
1798 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1799 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1800 not defined.
1801 * doc/autoconf.texi (Changed Directory Variables): New node,
1802 to document the whole `datarootdir' business a bit better.
1803 * NEWS: Update.
1804 * tests/torture.at (datarootdir workaround): Extend test.
1805 Prompted by report by Alexandre Julliard.
1807 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1809 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1810 when using default mode of IBM C 6 for AIX. Problem and two-line
1811 fix reported by Larry Jones.
1813 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1815 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1816 about literal '${datarootdir}' if a definition is found in the
1817 output file.
1819 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1821 * NEWS: Use "M4" rather than "m4" when appropriate.
1822 Problem reported by Eric Blake.
1823 * doc/autoconf.texi: Likewise.
1824 Use @acronym around BSD, GCC, and GNU when appropriate.
1825 (Why GNU M4): Renamed from "Why GNU m4".
1826 (Redefined M4 Macros): Mention that Posix
1827 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1828 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1829 to int.
1831 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1833 * bin/autom4te.in (handle_output): Do not forbid the empty
1834 pattern.
1835 * tests/tools.at (autoconf: the empty token): New test.
1837 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1839 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1840 calls, so that we do not care whether they are LIFO or FIFO;
1841 in the m4_wrap, do not check which diversion is the topmost
1842 one, just check that the stack is balanced at the end.
1843 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1844 base diversion forever--pop the previous diversion before
1845 opening the new one; consequently, remove the m4_wrap call.
1846 * lib/autotest/general.m4 (AT_INIT): Likewise.
1847 * tests/m4sugar.at: Do not use
1848 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1850 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1851 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1853 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1854 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1855 Rework example of m4wrap token-pasting trouble so that it doesn't
1856 care whether it's LIFO or FIFO.
1857 Fix some "contrary to"s that are awkward in English.
1859 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1861 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1862 to `yes' instead of `int$1_t' if the type is found, for more
1863 consistent configure output (where $1 is the number of bits).
1864 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1865 Suggested by Bruno Haible.
1867 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1868 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1869 with system headers. Report by Bruno Haible.
1871 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1873 * config/config.guess, config/config.sub: Sync from upstream.
1875 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1876 in order to avoid picking up an older installed frozen m4sh.m4f.
1877 Besides an outdated shell startup, this could have been created
1878 by an earlier M4 version with incompatible frozen file format.
1880 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1882 * README: Recommend m4 1.4.4 instead of 1.4.3..
1883 * doc/autoconf.texi: Likewise.
1884 (Special Chars in Names): Say that $(.FOO) is portable, as
1885 suggested by Stepan Kasal.
1886 (Installation Directory Variables, Build Directories):
1887 (Automatic Remaking, Subdirectories, Fortran Compiler):
1888 (Making testsuite Scripts, Defining Directories):
1889 Quote variable usages better.
1890 (Making testsuite Scripts): Add clean-local rule to makefile
1891 snippet, by Eric Blake.
1892 (Installation Directory Variables): Fix table item font.
1893 Reword slightly to clarify. Generalize advice about
1894 not using special characters to include all file-related
1895 vars, not just VPATH.
1896 (Special Chars in Variables): Warn about special characters in
1897 $(srcdir) too.
1898 (Assignments): Clarify default-value example as suggested by
1899 Ralf Wildenhues in
1900 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1901 (Special Shell Variables): Note leading ./ or ../, as suggested
1902 by Eric Blake.
1903 (Limitations of Builtins): Under cd, warn about CDPATH.
1904 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1905 Ralf Wildenhues.
1907 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1909 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1910 `@var', for texi2html.
1911 (Systemology): Some more word wrapping, for DVI output.
1912 (autom4te Invocation): The short option for `--melt' is `-M',
1913 not `-m'.
1915 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1917 * doc/autoconf.texi: More formatting and English tweaks,
1918 many suggested by Ralf Wildenhues.
1919 Reword to avoid "@code{...}'s" and the like, since it's ugly
1920 with Emacs info mode. discontents -> woes.
1921 Put a few "will"s back. time stamp -> timestamp.
1922 side-effect -> side effect.
1924 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1926 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1927 Warn about $@ not persisting. Problem reported by Julien Danjou in
1928 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1929 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1930 Mention other special chars, too.
1932 2006-06-14 Eric Blake <ebb9@byu.net>
1934 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1936 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1938 * doc/autoconf.texi: Some systematic minor improvements, as
1939 follows. Use "makefile" when talking about makefiles
1940 generally (which might be named "makefile" or "Makefile" or even
1941 "foo.mk"), "Makefile" when talking about a specific makefile
1942 called "Makefile". This unclutters the text from weird quotes
1943 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1944 values" rather than "@var{foo}s" and similar constructs containing
1945 "}s". Use "Make rules" rather than "Makefile rules". Minor
1946 English-language improvements. Change the prefix "sub-" to "sub"
1947 and "re-" to "re".
1948 Put blank lines around examples more consistently.
1949 Avoid "rather" and "very" as intensifiers.
1950 Avoid "will" as an auxiliary.
1951 (Limitations of Make): Split this node into....
1952 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1953 (Leading _ in Macro Names, Backslash-Newline-Newline):
1954 (Backslash-Newline Comments, Long Lines in Makefiles):
1955 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1956 (obj/ and Make, make -k Status, VPATH and Make):
1957 (VPATH and Double-colon, $< in Explicit Rules):
1958 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1959 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1960 New nodes, resulting from splitup of Limitations of Make.
1961 All cross-references changed. Raise the top node from
1962 a section to a chapter, and all subnodes accordingly.
1963 Redo the introductory wording to match the new organization.
1964 (Installation Directory Variables): Use an example that is
1965 closer to what Autoconf actually does. Mention that VPATH's
1966 value should not contain metacharacters or white space.
1967 (Fortran Compiler): Fix a VPATH bug in an example.
1968 (Leading _ in Macro Names): Mention that this problem is no longer
1969 of practical concern.
1970 (VPATH and Make): Reword the advice to make it clearer
1971 that Autoconf and Automake support VPATH in non-GNU make, but
1972 many packages have bugs in this area.
1973 ($< in Explicit Rules): Refer to Build Directories rather
1974 than using a (non-VPATH-safe) example.
1975 (Automatic Rule Rewriting): Mention the sort of disaster that
1976 can ensue with Solaris-style rule rewriting with VPATH.
1978 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1980 * doc/install.texi (Compilers and Options): Weaken the
1981 suggestion to use GNU make for VPATH builds.
1983 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1984 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1986 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1987 in regular expression.
1989 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1991 * doc/autoconf.texi (Installation Directory Variables):
1992 Drop extra @samp from `@table @samp' item.
1993 (Limitations of Usual Tools): Comment fix.
1994 Do not nest @samp just to point to other table items.
1995 (Writing testsuite.at) <AT_CHECK>: The second argument to
1996 `@dvar' is already @samp'ed.
1997 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1998 do not use @var in the second argument.
2000 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2002 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2003 $as_shell.exe too. Problem reported by Andreas Buening in
2004 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2006 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2008 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2009 `unused variable' compiler warning, for `-Wall -Werror'.
2010 Reported by Jaap Haitsma in
2011 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2013 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2015 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2016 case the compiler dumps core. Problem reported for
2017 OpenServer 5.0.7 by Tim Rice in
2018 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2019 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2020 Likewise.
2022 2006-06-06 Tim Rice <tim@multitalents.net>.
2024 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2025 "ERROR" only shows up in "make check" output if there is an
2026 error.
2028 2006-06-06 Eric Blake <ebb9@byu.net>
2030 * tests/tools.at (automatically allowed tokens): Fix typo.
2032 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2034 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2036 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2037 typically overflows on x86 CPUs, even though the C standard
2038 requires otherwise.
2040 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2042 * configure.ac (AC_INIT): Bump to 2.59e.
2043 * NEWS: Update.
2045 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2047 Version 2.59d.
2049 * config/texinfo.tex: Sync from upstream.
2051 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2052 seen, invoke libtoolize with `--ltdl' argument.
2053 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2054 * NEWS: Update.
2055 Suggested by Eric Blake.
2057 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2059 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2060 reported by Ralf Wildenhues.
2061 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
2063 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2065 * THANKS: Update.
2067 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2069 * doc/autoconf.texi: Modernize some of the references to Solaris.
2071 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2073 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2074 message issued by AC_REQUIRE.
2075 * tests/m4sugar.at: Check m4_require's error message.
2076 * tests/base.at: Check AC_REQUIRE's error message.
2077 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2078 to...
2079 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2080 AT_CHECK_M4.
2081 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2082 `expout' as the last parameter.
2083 * tests/tools.at: Adapt to the above change.
2085 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2087 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2088 information about race-free implementations of mkdir.
2090 2006-06-04 Eric Blake <ebb9@byu.net>
2092 * bin/autoreconf.in (help): Document M4 environment variable.
2093 * bin/autoconf.as (Usage): Likewise.
2094 * bin/autom4te.in (help): Likewise.
2095 * doc/autoconf.texi (autom4te Invocation): Likewise.
2097 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2099 * NEWS: GNU make now recommended for VPATH builds.
2100 Mention that some macros are now documented to be obsolescent.
2101 * doc/autoconf.texi:
2102 Prefer "current" to "modern" to describe
2103 currently-used (albeit perhaps old-fashioned) hosts.
2104 Mention which ancient features no longer need to be worried about.
2105 setgid -> set-group-ID
2106 setuid -> set-user-ID (these are the Posix terms)
2107 Fix some misuses of "only".
2108 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2109 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2110 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2111 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2112 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2113 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
2114 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
2115 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2116 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2117 Mention that these macros are obsolescent.
2118 (Installation Directory Variables): shall -> should
2119 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2120 Mention that it's now safe to use 3 and 4.
2121 (Limitations of Usual Tools): cp -r is now specified by Posix.
2122 Omit longwinded and obsolescent discussion of cp -f.
2123 Modernize discussion of expr, ls.
2124 (Limitations of Make): Modernize discussion of VPATH builds.
2125 Mention $? as a workaround in some cases.
2126 * doc/install.texi (Basic Installation):
2127 Mention "./configure; make; make install" first. Be more
2128 specific about why this file is generic. Remove unnecessary
2129 parens. Remove misleading "only". Remove obsolete advice
2130 about csh. Don't say "configure" takes awhile; say it
2131 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2132 and CC=c99 rather than CC=c89, as these are blessed by current
2133 Posix. Recommend GNU make if doing a VPATH build.
2135 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2137 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2138 examples involving shell prompts.
2140 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2141 and Paul Eggert <eggert@cs.ucla.edu>
2143 * doc/autoconf.texi (Here-Documents): Add details about the
2144 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2145 use "here-documents" instead of "here documents".
2147 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2149 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2151 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2153 * doc/autoconf.texi (File System Conventions): Warn about ":"
2154 anywhere in directory names.
2156 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2158 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2159 about quoting the case statement, just in case.
2160 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2161 was fixed in ksh93g; reported by Ralf Wildenhues.
2163 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2165 * doc/autoconf.texi (System Services): Do not document
2166 overriding EXEEXT via ac_cv_exeext=ext.
2167 (Particular Programs) <AC_PROG_MKDIR_P>:
2168 Document that ${MKDIR_P} understands --.
2169 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2170 comment.
2172 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2174 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2175 argument with leading hyphen. Problem reported by Paul Eggert.
2177 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2179 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2180 about quoting ac_try: quote all of it, if any of it seems suspicious.
2181 This means we don't have to worry about ${ or sed any more.
2182 Also, double-quote the case statement, to work around misuses via
2183 underquoting as reported by Ralf Wildenhues in
2184 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2185 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2186 undocumented and dangerous macro.
2187 Problem reported by Ralf Wildenhues in
2188 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2190 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2192 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2193 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2194 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2196 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2198 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2199 since evidently some packages rely on the old, broken behavior.
2200 Problem reported by Ralf Wildenhues in
2201 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2202 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2203 pre-2006-05-26 definitions, but leave in the comments that
2204 these macros are dangerous and should not be used.
2205 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2206 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2207 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2208 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2209 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2211 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2213 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2214 the use of 'tr', since this is our only use of 'tr'.
2216 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2217 and Paul Eggert <eggert@cs.ucla.edu>
2219 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2220 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2222 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2224 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2225 the output file in the `${datarootdir}' test.
2227 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2228 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2230 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2231 mention of `datarootdir' in the input file(s), but literal
2232 `${datarootdir}' in the output file, and we haven't warned yet,
2233 then warn as well: the user may have (erroneously) used
2234 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2235 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2236 * tests/torture.at (datarootdir workaround): Extend this test.
2237 * NEWS: Update.
2239 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2240 and Paul Eggert <eggert@cs.ucla.edu>
2242 * doc/autoconf.texi (autoheader Invocation): The first argument to
2243 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2244 alternatives and clear up the language a bit.
2246 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2248 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2249 ac_config_guess, ac_config_sub, ac_configure.
2250 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2251 Fix typo that prevented an unnecessary space from being removed.
2252 Problems reported by Ralf Wildenhues in:
2253 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2255 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2257 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2258 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2259 Don't use the term "thread-safe" to talk about mkdir race
2260 conditions, since the problem is more a process than a thread
2261 issue. Problem reported by Stepan Kasal in:
2262 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2263 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2264 the test for 'install' more closely. Look at MKDIR_P first.
2265 Look in the PATH, and at /opt/sfw/bin.
2266 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2267 Don't bother to try mkdir -p, since we already check mkdir --version;
2268 just look at the version number. (There's no easy way to check
2269 for race-free implementations.)
2270 * tests/tools.at (autoconf: subdirectories): Adjust to above
2271 changes, since MKDIR_P now might end in "/mkdir -p".
2273 * doc/autoconf.texi (autoheader Invocation): Mention that the
2274 first arg of AC_DEFINE_UNQUOTED must be a literal.
2275 Problem reported by Ben Pfaff in
2276 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2278 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2279 * doc/autoconf.texi (Special Chars in Variables): New section.
2280 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2281 (Installation Directory Variables): Quote $(datadir) better.
2282 (Limitations of Builtins): Describe some of eval's trickiness.
2284 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2285 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2286 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2287 in front of every arg, not just trailing args. Quote apostrophes.
2288 (_AC_EVAL_ECHO): New macro.
2289 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2290 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2291 removed.
2292 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2293 exposed by quoting of eval argument. Put the command on line line
2294 so it logs better.
2295 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2296 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2297 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2298 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2299 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2300 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2301 Use eval more safely.
2302 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2303 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2304 to be replaced.
2305 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2306 lines, exposed by quoting of eval argument.
2308 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2309 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2311 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2312 initialization of `ac_cv_exeext', do not override it if it was
2313 already set, unless it was set to `no', for compatibility with
2314 Autoconf-2.13, and comment this.
2315 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2316 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2317 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2318 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2319 Document that this test may be overridden by setting
2320 `ac_cv_exeext'.
2322 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2324 Revert these two patches:
2326 2006-04-06 Eric Blake <ebb9@byu.net>
2327 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2328 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2329 2006-04-01.
2331 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2332 Clean up _AC_COMPILER_EXEEXT* macros.
2333 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2334 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2335 ac_file to the name of the default output file and call
2336 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2337 initial `rm' of the candidate files...
2338 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2339 the same list in subsequent `rm' calls, and for the temporary
2340 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2341 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2342 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2343 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2344 no longer needed) by libtool. Make it a cache check.
2345 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2346 copied here by mistake.
2347 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2348 _AC_COMPILER_EXEEXT.
2349 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2350 _AC_COMPILER_OBJEXT directly.
2351 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2353 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2355 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2356 Fix description of how the buggy `sed' works.
2358 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2360 Sync from Automake:
2362 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2363 ENOLCK. Only mention `make -j' when applicable. Only raise
2364 fatal errors when `make -j' is involved. Improve error message.
2366 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2368 * doc/autoconf.texi (Here-Documents): We now know more about
2369 the variable expansion in here documents bug.
2370 Thanks to Tim Rice and Stepan Kasal.
2372 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2373 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2375 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2377 * tests/autotest.at (Multiline command from M4 expansion):
2378 No failure to be expected if the shell quotes newlines in
2379 commands in the `set -x' output. Report by Tim Rice.
2380 * THANKS: Update.
2382 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2384 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2385 expansion in the here-documents used by config.status, as that
2386 runs afoul of the Korn shell version M-12/28/93d bug described in
2387 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2388 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2389 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2391 2006-05-23 Jim Meyering <jim@meyering.net>
2393 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2394 Fix typo introduced with 2006-04-02 change. It reversed the sense
2395 of the test.
2397 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2399 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2400 ac_dB slightly, to save bytes in the script.
2401 Max out at 50 lines, rather than 96; this is more likely
2402 (though not guaranteed) to avoid obscure 'sed' failures.
2404 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2406 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2407 `tr -d -' as bad option argument. Work around this by deleting
2408 an unrelated character.
2409 Report by Tim Rice <tim@multitalents.net>.
2411 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2412 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2413 Stepan Kasal <kasal@ucw.cz>
2415 * doc/autoconf.texi (Particular Programs): Do not promise that
2416 we always prefer the GNU version of the program, and that we
2417 search according to PATH; both rules can have exceptions.
2418 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2419 AC_PROG_SED. Move descriptions of limitations
2420 to the Limitations of Usual Tools section.
2421 (Limitations of Usual Tools) <sed>: Mention script length
2422 limitations with Solaris /usr/ucb/sed.
2423 <grep>: Fix wording for empty alternative. Mention that -c and
2424 -l should not be combined, and that -E and -F should not be
2425 combined.
2427 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2428 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2430 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2431 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2433 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2435 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2436 AC_DEFINE is now passed to m4_pattern_allow.
2437 * NEWS: Mention that; likewise for AC_SUBST.
2438 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2439 the parameter to m4_pattern_allow.
2440 * tests/tools.at: Add a check for that.
2442 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2444 * lib/autoconf/status.m4: Fix typos.
2446 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2448 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2449 only the files that this macro generates.
2451 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2453 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2454 the HP-UX sed limitation of 99 commands, labels do not count.
2455 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2456 in the comment.
2457 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2459 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2461 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2462 Import the following fix from coreutils:
2464 2006-01-13 Jim Meyering <jim@meyering.net>
2466 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2467 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2468 not double-quote uses of that variable, to accommodate the rare
2469 case in which getmntent is available in none of the libraries
2470 checked. This happens at least on FreeBSD 5.0.
2472 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2474 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2475 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2476 some other programs unwisely rely on these undocumented vars.
2477 But put in warning comments about them.
2478 Problem reported by Ralf Wildenhues in
2479 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2480 * NEWS: Document that these variables are intended to go away.
2482 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2484 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2485 and set the language to C++ (analogous to the equivalent Fortran
2486 tests).
2488 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2489 * doc/autoconf.texi (C++ Compiler): Document it.
2490 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2491 * NEWS: Update.
2493 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2495 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2496 that caused config.status to generate 100-command sed scripts; the
2497 portable limit is 99.
2499 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2501 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2502 variable `ac_d' instead of `d' to avoid infringing namespace.
2503 Report by Ralf Menzel.
2505 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2507 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2508 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2509 * tests/tools.at (autoconf: subdirectories): New test, taken from
2510 the corresponding problem report by Ralf Wildenhues in:
2511 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2513 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2514 Quote some uses of shell variables if they might suffer unexpected
2515 globbing. This doesn't fix all instances of quoting problems that
2516 I found, just the easy ones that look safe.
2517 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2518 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2519 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2520 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2521 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2522 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2523 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2524 Likewise.
2525 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2526 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2528 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2530 * bin/autoreconf.in ($help): Reword according to the manual.
2531 Suggested by Olly Betts.
2533 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2534 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2536 * bin/autoreconf.in: Pass the directory argument to
2537 `require_configure_ac'. Fix comment.
2538 * tests/torture.at (Configuring subdirectories): Expose this.
2539 Reported by Olly Betts.
2541 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2543 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2544 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2545 Automake as follows:
2547 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2548 `$configure_in' instead of `configure.in', to preserve
2549 directory component.
2551 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2553 * config/config.guess, config/config.sub, config/texinfo.tex,
2554 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2556 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2558 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2559 test for C99 conformance; (bool) 0.5 is an integer constant
2560 expression, but (bool) -0.5 is not. Problem reported by Fedor
2561 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2563 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2565 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2566 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2567 Warn about obsolete install-sh files. Remove stray sentence
2568 fragment and fix cross reference.
2569 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2570 install -d; this undoes the 2006-05-10 change.
2571 (MKDIR_P): Mark with AN_MAKEVAR.
2572 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2573 that we don't require $INSTALL to be thread-safe. Move comments
2574 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2575 of AC_PROG_INSTALL. Output a message saying that we're checking
2576 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2577 MKDIR_P instead of AC_SUBST.
2578 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2579 Special magic for MKDIR_P, too.
2580 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2581 a dnl.
2582 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2584 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2586 Sync from Automake, as follows:
2588 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2589 * config/install-sh: Initialize IFS, so field splitting isn't
2590 turned off later.
2591 * config/mkinstalldirs: Likewise.
2592 * config/missing: Remove superfluous quotes. Replace all uses of
2593 `[' by `test', for consistency, and for..
2594 * config/missing (sed_minuso, sed_output): New variables.
2595 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2596 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2597 Fixes `missing' to detect `--output' for help2man. Fixes
2598 PR automake/483. Report by Dennis J. Linse.
2599 (autom4te): Document in `missing --help'.
2601 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2603 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2604 * config/install-sh: Don't use 'path' to talk about file names,
2605 as per GNU coding standards. Close a race condition reported by Ralf
2606 Wildenhues and Stepan Kasal. There is still a race condition
2607 on hosts that predate Posix 1003.1-1992, but we can't help this.
2608 Don't mishandle weird characters like space on pre-Posix hosts.
2609 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2610 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2611 AC_PROG_MKDIR_P from AS_MKDIR_P.
2612 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2613 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2614 earlier editions are not (including Automake 1.8.3).
2615 Do not suggest mkinstalldirs for thread-safety.
2616 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2617 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2618 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2619 presence of special characters and race conditions.
2620 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2621 in Autoconf's name space.
2623 2006-05-10 Bruno Haible <bruno@clisp.org>
2624 and Paul Eggert <eggert@cs.ucla.edu>
2626 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2627 from Automake with minor changes.
2628 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2630 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2632 * config/install-sh: Update to Automake CVS version, as follows:
2633 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2634 * lib/install-sh: Simplify the expr implementation of dirname.
2635 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2636 * lib/install-sh: Handle --, and diagnose unknown options.
2638 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2640 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2641 `./autom4te' to create `./testsuite', since the `all' target
2642 will ensure its presence, but `installcheck' should not create
2643 the uninstalled wrappers.
2645 * tests/torture.at (Unusual Automake input files): Skip if we
2646 detect automake < 1.8.
2648 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2650 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2651 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2652 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2653 * NEWS: Update.
2655 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2657 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2658 munge (multiple) white space and other oddities.
2659 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2660 single quotes in variable assignment.
2661 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2662 and similar failures by adding multiple spaces, tabs, and other
2663 special characters.
2664 Report and different test suggested by Francesco Romani
2665 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2667 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2668 single quotes, we only need to search for single quotes; this
2669 both simplifies the search pattern, and makes us less
2670 susceptible to `echo' variations for arguments not containing
2671 single quotes.
2672 (_AC_ARG_VAR_VALIDATE): Likewise.
2674 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2676 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2677 `$*' and IFS concatenation issue with traditional shells and
2678 bash-2.04. Report by Seanster@Seanster.com.
2680 2006-05-03 Bruno Haible <bruno@clisp.org>
2682 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2683 precisely which Mac OS X versions have the od problem.
2685 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2687 * doc/autoconf.texi: Use @option systematically.
2689 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2690 and Bruno Haible <bruno@clisp.org>
2692 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2693 about 'od'.
2694 (Integer Overflow): Mention the special case of integer division
2695 overflow.
2697 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2699 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2700 traditional shells like the Solaris one that do not use the
2701 first IFS character for assembling `$*'.
2702 Prompted by a related report from autoconf_bug@nro.ca.
2704 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2705 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2707 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2708 Mention more problems with the -e option.
2710 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2712 * NEWS: Typo.
2713 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2715 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2716 in URLs to improve DVI formatted output (requires texinfo 4.6).
2717 (System Services, Systemology, Shellology): Likewise.
2718 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2719 output.
2721 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2722 continuous text.

2725 (Obsolete Macros): Likewise.
2726 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2727 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2728 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2730 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2732 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2734 * ChangeLog: Typo.

2741 /bin/sh set unsorted output.
2742 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2743 * tests/local.at: Likewise.
2745 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2747 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2748 (Integer Overflow, Null Pointers, Buffer Overruns):
2749 (Floating Point Portability, Exiting Portably): New sections.
2750 (Writing Test Programs): Fix some langauge. Recommend exiting
2751 with status 1, not merely nonzero. Clarify exit declaration.
2752 (Run Time): Move C exit status stuff to new Exiting Portably section.
2753 (Systemology): Mention Posix and levenez. Update v7 reference.
2754 (Portable Shell): Mention the Posix shell.
2756 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2758 * bin/autoconf.as (me): Replace by as_me.
2760 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2762 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2763 since as_me isn't set yet.
2765 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2767 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2768 a few minor bugs in this area.
2770 * doc/autoconf.texi (Programming in M4sh): Comment out the
2771 documentation of AS_BASENAME, for now.
2772 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2773 (Limitations of Builtins) <basename>: Do not refer to
2774 AS_BASENAME.
2775 * bin/autoconf.as (me): Don't use AS_BASENAME.
2776 (dir): Remove the unused variable.
2777 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2778 AS_DETECT_REQUIRED. All uses changed.
2779 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2780 All uses changed.
2781 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

2791 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2793 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2794 of "run time" and "run-time" changed to "runtime", for consistency.

2796 * lib/autoconf/functions.m4: Likewise.
2797 * lib/autoconf/general.m4: Likewise.
2798 * lib/autoconf/headers.m4: Likewise.
2800 * doc/autoconf.texi (Run Time): Document the exit status situation
2801 with more accuracy and detail.
2803 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2805 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2806 Archive is not officially `GNU' any more. Update URL.
2807 (Defining Directories): Likewise
2808 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2810 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2812 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2813 newline from the `trap' code to finish `config.log'; the NetBSD
2814 /bin/sh resets the exit status after an empty command, as
2815 documented in doc/autoconf.texi.
2816 Reported by Dalibor Topic <robilad@kaffe.org>.
2818 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2820 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2821 Suggested by Bruno Haible.
2823 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2825 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2826 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2827 Instead, just list the shells that we know work.
2828 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2829 changed. Be more cautious about the _cv_ variable.
2830 * tests/tools.at (Syntax of the shell scripts): Check the
2831 _cv_ variable once, at first, to avoid an internal autoconf error
2832 when sh -n does not work.
2834 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2836 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2838 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2840 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2841 use ">&-" since we're only 99.999% sure that this is portable,
2842 and since the MinGW bug is fixed in a different way.
2843 * lib/autotest/general.m4 (AT_INIT): Likewise.
2845 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2847 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2848 before opening config.log, to avoid hitting a bug on MinGW.
2850 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2852 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2853 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2854 This works around a MinGW bug reported by Eric Paire.
2855 Make sure that all writes to the log file append to it,
2856 rather than possibly losing data.
2857 * lib/autotest/general.m4 (AT_INIT): Likewise.
2859 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2861 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2862 description.
2864 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2866 * NEWS: Update.
2868 * configure.ac (AC_INIT): Bump to 2.59d.
2870 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2872 Version 2.59c.
2874 * Makefile.maint (news-date-check): Do not require a leading `*'
2875 before the release date in NEWS.
2877 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2878 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2880 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2881 the instantiated file do not contain the string 'datarootdir'
2882 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2883 @mandir@, replace the reference '${datarootdir}' by the value.
2884 * tests/torture.at (datarootdir workaround): New test.
2885 * NEWS: Advertise this temporary fixup.
2886 Based on a patch by Bruno Haible, reported and analyzed by
2887 Paul Eggert and Noah Misch.
2889 2006-04-12 Eric Blake <ebb9@byu.net>
2891 * tests/autotest.at (Debugging a failed test): Fix comment.
2893 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2895 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2896 all the changes since 2006-04-07.
2898 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2900 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2901 succeeded, but `ln -s file dir' failed, take care to remove the
2902 leftover target before the next test, to prevent its spurious
2903 failure; also make sure `ln file dir' works before selecting it.
2904 Thanks to Keith Marshall for pointing this out.
2905 * THANKS: Update.
2907 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2908 assignments in `at_debug_args', so that we put them correctly
2909 in the `run' script.
2910 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2911 Reported by Eric Blake.
2913 2006-04-11 Eric Blake <ebb9@byu.net>
2915 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2916 top-level tests after micro-suite has been run. Used in...
2917 (Debugging a successful test, Debugging script and environment),
2918 (Debugging a failed test): ...these new tests. The first of these
2919 is fixed by...
2920 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2921 macro, split out from...
2922 (AT_INIT): ...here, so that using -d also generates a run script.
2923 Document that -d inhibits top-level logging.
2924 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2925 inhibits top-level logging; debug scripts are created.
2927 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2928 check.
2929 * tests/autotest.at (Empty test, Empty check): New test to check it.
2931 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2932 from gcc.
2934 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2936 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2937 the files if a problem appears. Make the empty *.at files
2938 read-only, too. Proposed by Ralf Wildenhues.
2940 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2942 * config/Makefile.am: Add comment to force updated Makefile.in.
2944 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2945 space only patch to this file, this patch causes the Makefile.in
2946 files that include freeze.mk to be updated, and thus have a
2947 newer time stamp again, which in turn makes a pristine CVS
2948 checkout have correct time stamps.
2950 * Makefile.maint (cvs-sv): New macro, to be used..
2951 (config.guess-url_prefix, config.sub-url_prefix)
2952 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2953 point to CVS text checkout of Gnulib files.
2954 (copyright-check): Bump current year.
2955 (announcement): Do not hard-wire `./announce-gen'.
2956 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2957 correctly.
2958 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2959 `chmod +x'.
2960 (wget_files): Update config.guess, config.sub, texinfo.tex by
2961 `wget-update', now that their URLs work again.
2963 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2965 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2966 Problem noted by Paul D. Smith.
2968 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2970 * doc/autoconf.texi: Remove unused words from word list.
2971 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2972 .x-sc_trailing_space: New files.
2974 * doc/standards.texi: Sync from gnulib.
2976 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2977 `LIBOBJDIR' as experimental.
2979 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2980 with a target directory; it's internally implemented as `cp'
2981 anyway, but since Autoconf advertises the possibility to use
2982 a target directory when LN_S is `ln -s', we need to find out.
2983 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2984 analyzed by Keith Marshall <keith.marshall@total.com>.
2986 * THANKS: Update.
2988 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2990 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2991 confdefs.h as-is. In general, if it has backslash-newline or the
2992 like, then it doesn't work either to sort or to remove empty
2993 lines.
2995 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2997 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2999 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3001 * lib/autom4te.in (Automake-preselections): Preselect
3002 _AM_SUBST_NOTMAKE.
3004 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3006 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3007 apostrophe within a single-quoted string, as this is the usual
3008 tradition and is easier to read than '"'"'. Don't rely on the
3009 shell treating "$/" like '$/'. Use a more-consistent indenting
3010 style for the trap.
3012 2006-04-09 Eric Blake <ebb9@byu.net>
3014 * tests/autotest.at (Backquote command substitution),
3015 (Multiline backquote command substitution): Remove mistaken
3016 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3017 applied...
3018 (Parenthetical command substitution, Multiline parenthetical
3019 command substitution): here.
3021 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3023 Import macros from gnulib (often changing their name).
3025 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

3037 (Pointers): Add Gnulib URL.
3038 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
3039 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3040 Gnulib section.
3041 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
3042 suggest a #define rather than a typedef for _Bool, and mention
3043 Gnulib rather than trying to substitute stdbool code.
3044 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
3045 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
3046 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
3047 AC_STRUCT_DIRENT_D_TYPE.
3048 (Particular Types): Mention stdint.h and inttypes.h as standard
3049 headers too.
3050 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
3051 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
3052 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
3053 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
3054 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3055 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3056 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3057 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3058 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3059 (Coding Style). Don't mention m4_expand_once.
3060 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
3061 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
3062 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
3063 (AC_CHECK_FUNCS): Use it.
3064 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
3065 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
3066 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
3067 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
3068 (AC_HEADER_ASSERT): New macro.
3069 (AC_HEADER_STDBOOL): Don't assume "#error" works.
3070 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
3071 Catch a bug in an HP-UX C compiler.
3072 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
3073 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
3074 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

3077 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
3078 New macros.
3080 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
3081 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
3083 2006-04-08 Stepan Kasal <kasal@ucw.cz>
3085 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
3086 of the warning introduced by the 2001-08-28 change.
3088 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
3089 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3091 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
3092 variables shall be overriden by the cache.
3093 * tests/torture.at (AC_ARG_VAR): Test also with a first value
3094 that contains braces.
3096 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3098 Revert the patch from 2006-04-01 and only improve
3099 _AS_DETECT_BETTER_SHELL:
3101 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3102 skip nonexistent directories.
3103 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3104 only shell candidates which exist.
3105 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3106 * lib/autotest/general.m4 (AT_INIT): No need to give three
3107 parameters to _AS_PATH_WALK.
3109 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3110 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3112 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3113 distinguish m4sugar macros.
3114 * tests/tools.at (autoupdating with aclocal and m4_include):
3115 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3116 test case by Noah Misch <noah@cs.caltech.edu>.
3118 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3120 Revert my change from 2006-03-17, in other words:
3121 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3122 and DUALCASE=1.
3123 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3124 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3125 it is set.
3127 2006-04-07 Eric Blake <ebb9@byu.net>
3129 * doc/autoconf.texi (Programming in M4sh): Document that
3130 AS_MKDIR_P exits the script on failure.
3131 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3133 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3135 * config/elisp-comp, config/install-sh, config/mdate-sh,
3136 config/missing, config/mkinstalldirs: Sync from Automake.
3138 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3139 from Automake.
3141 * doc/make-stds.texi: Sync from gnulib.
3143 2006-04-06 Eric Blake <ebb9@byu.net>
3145 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3146 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3147 2006-04-01.
3149 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
3150 Eric Blake <ebb9@byu.net>,
3151 Paul Eggert <eggert@cs.ucla.edu>,
3152 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3154 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3155 whether `set' quotes correctly: redirect stderr of the tested
3156 `set', and use a subshell, for Ultrix; use `sed' instead of
3157 `grep' for zsh `set' which may write binary output; match only
3158 at the beginning of a line, to avoid false positives.
3159 In order to avoid false positives by unrelated variables with
3160 multiline content, put the dump algorithm in a subshell and
3161 unset all variables containing newlines (except some which are
3162 special to the shell). Warn about cache variables that are
3163 unset.
3165 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3225 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

3278 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3279 Use 'comm' rather than N instances of grep; this also fixes a bug

3366 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3367 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3368 ac_file to the name of the default output file and call
3369 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3370 initial `rm' of the candidate files...
3371 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3372 the same list in subsequent `rm' calls, and for the temporary
3373 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3374 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3375 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3376 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3377 no longer needed) by libtool. Make it a cache check.
3378 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3379 copied here by mistake.
3380 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3381 _AC_COMPILER_EXEEXT.
3382 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

3418 subordinate tools.
3419 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
3420 * doc/autoconf.texi (autoreconf Invocation): Document it.
3422 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

3456 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3457 switch all of them on and of when necessary. Fixes the bug when

3509 checked for existence, so we don't barf over a nonexisting
3510 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
3512 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4082 Fix quoting of output line (triggered for many AC_SUBST_FILEs).
4083 Fix macro quoting. Fix output for n * 98 substituted variables.
4085 2005-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4087 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Initialize
4088 `tmp' to avoid file removal race.
4090 2005-11-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4092 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
4093 ac_clean_files and LIBOBJS.
4095 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4097 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
4098 Factor functionality to..
4099 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
4100 `AC_SUBST($1)' in the public version.
4101 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
4102 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
4103 ac_pt_* variables.
4105 2005-11-01 Stepan Kasal <kasal@ucw.cz>
4107 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
4108 filesystems.
4110 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4112 * NEWS: Move AH_HEADER mention to right place.
4114 2005-10-27 Stepan Kasal <kasal@ucw.cz>
4116 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
4117 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4119 2005-10-25 Stepan Kasal <kasal@ucw.cz>
4121 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
4122 conftst2.$ac_objext.
4123 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4125 2005-10-24 Stepan Kasal <kasal@ucw.cz>
4127 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
4128 conftest.o, to see whether the compiler really obeys; rm the object
4129 file before and after the test and register it with ac_clean_files.
4130 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
4132 2005-10-21 Stepan Kasal <kasal@ucw.cz>
4134 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
4135 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
4136 code so that the most common case requires less forks.
4138 2005-10-20 Stepan Kasal <kasal@ucw.cz>
4140 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
4141 not portable; thanks to Paul Eggert and Alexandre.
4143 * NEWS: Fix an old typo.
4145 2005-10-20 Jim Meyering <jim@meyering.net>
4147 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
4148 the latter'', in two places.
4150 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
4152 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
4153 AC_LANG_PROGRAM, fixing a typo. Don't give details about
4154 the inner workings of AC_LANG_FUNC_LINK_TRY.
4155 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
4156 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4157 by the function rather than ignoring it.
4158 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4159 comparing its address. Intel's interprocedural optimization was
4160 outsmarting the old heuristic. Problem reported by
4161 Mikulas Patocka.
4163 2005-10-19 Stepan Kasal <kasal@ucw.cz>
4165 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
4167 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
4169 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

4172 2005-10-04 Stepan Kasal <kasal@ucw.cz>
4174 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
4175 before removing it (chmod -R u+rwx); there are three instances of this.
4177 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4178 Stepan Kasal <kasal@ucw.cz>
4180 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4181 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4182 make its content writable before removing it. Remove an errorneous
4183 comment from the end, where the logs of the failed tests are copied
4184 to the main log file.
4186 2005-09-27 Stepan Kasal <kasal@ucw.cz>
4188 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
4189 in case the computer is too quick. Double quote the configure.ac
4190 snippets.
4192 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
4193 problems if the testsuite were running too fast.
4195 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4197 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4198 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4199 (which belong to Xt, not X itself). See Debian bug 327655.
4200 * NEWS: Mention this.
4202 2005-09-07 Stepan Kasal <kasal@ucw.cz>
4204 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
4206 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
4208 * config/move-if-change: Don't output "$2 is unchanged";
4209 suggested by Ben Elliston. Handle weird characters correctly.
4211 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4213 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4214 calls, so that the final expansion of this macro is shorter.
4215 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4216 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4217 the cleanup there. Use AS_VAR_* macros, to be more general.
4218 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4220 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4222 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
4224 2005-09-01 Stepan Kasal <kasal@ucw.cz>
4226 * doc/autoconf.texi (Configuration Headers): Add an index entry
4227 for AH_HEADER.
4229 2005-08-26 Pavel Roskin <proski@gnu.org>
4231 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
4232 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
4233 running xmkmf.
4235 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4237 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4238 The previous patch didn't work, so try a better one.
4240 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4242 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4243 in the example. Reported by Bruno Haible.
4244 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4245 "if $undefined_var;" succeeds with my shell.
4247 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4248 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4249 but change the m4_divert_text to m4_divert_once.
4251 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4253 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4254 Work around bug in Solaris /usr/xpg4/bin/awk.
4255 The bug is present in at least Solaris 8 through 10.
4257 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4259 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4260 some evil values and relying on the fact that $* concatenates the
4261 parameters by the first character from IFS.
4263 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4264 Stepan Kasal <kasal@ucw.cz>
4266 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4267 first header appears, define AH_HEADER.
4268 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4269 Update limitations about when to call AC_CONFIG_HEADERS.
4270 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4271 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4272 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4273 ``Configuration Actions''; fix their index entries.
4275 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4276 options correctly. Process N-M as M-N if M is smaller than N.
4277 Process ranges correctly so that N-N will run only N.
4278 Sort and uniquify the tests that will be run. If there is more
4279 than one test, reinsert the banners for the tests.
4280 * tests/autotest.at (Keywords): Unmark XFAIL.
4282 2005-08-23 Stepan Kasal <kasal@ucw.cz>
4284 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4285 before passing the macro name to AH_TEMPLATE.
4287 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4288 now opens log after option processing; in particular, --version
4289 and --help do not touch config.log.
4291 * Makefile.maint: Revert the change from 2005-08-12.
4293 2005-08-22 Stepan Kasal <kasal@ucw.cz>
4295 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
4296 common code to...
4297 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
4299 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4301 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4302 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4303 Language cleanup.
4305 * doc/autoconf.texi (Defining Symbols, Changed Results):
4306 Prepend to LIBS, not append, in examples.
4308 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4310 When building in place, set srcdir="."; suggested by Tim Van Holder.
4312 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4313 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4314 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4315 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4316 does not mean "no --srcdir option".
4318 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4320 * tests/autoscan.at (autoscan): New file.
4321 * tests/suite.at: Use it.
4322 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4323 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
4325 * tests/autotest.at (Keywords): Test keywords combinations.
4327 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4329 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4330 add "2>&1"; gzip 1.2.4 prints help on stderr.
4332 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4334 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4335 was pushdef'ed twice while popped only once. Push it only once.
4336 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4338 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4340 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
4341 prefixed by mere "===", not "configure: === ".
4343 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
4345 * Makefile.maint: Update from Bison.
4347 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4348 "<tab>" in comment, so that the point is understandable.
4350 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4352 Rewrite substantial part of lib/autoconf/status.m4.
4353 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4354 and CONFIG_COMMANDS are not processed in four separate loops.
4355 Instead, there is one main loop. This alows that the common code
4356 is expanded only once, thus config.status (and configure) is smaller.
4358 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4359 the AC_LIST_FILES and cousins macros are no longer used.
4361 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4362 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4363 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4364 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4365 contain the initialization, nor the for loop, nor the associated
4366 commands; all these go to ...
4367 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4368 _AC_OUTPUT_CONFIG_STATUS.
4369 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4370 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4371 (_AC_OUTPUT_FILE): The creation of the sed script ...
4372 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4373 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4374 _AC_OUTPUT_MAIN_LOOP.
4375 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4376 _AC_CONFIG_COMMANDS): Use ...
4377 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4378 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4379 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4380 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4381 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4382 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4383 ... new macros.
4384 (_AC_CONFIG_UNIQUE): Update.
4385 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4386 Replaced by this ...
4387 (_AC_LIST_TAGS): ... new common macro.
4388 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4389 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4390 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4391 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4392 this didn't belong to the `config commands' section.
4393 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4394 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4395 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4396 to the `config commands' section either.
4397 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4398 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4400 ... and many changes to the comments nearby.
4402 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4403 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4404 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4405 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4406 (#define header templates): The comment at the top of the generated
4407 header now includes the name(s) of the source file(s).
4409 Several unrelated small changes:
4411 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4412 parameter to AC_DIAGNOSE.
4413 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4414 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4415 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4416 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4417 with AU::AC_OUTPUT.
4418 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4419 in AC_OUTPUT doesn't double-quote it either.
4420 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4421 parameters.
4423 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4425 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4426 versions of Portland Group compiler produce single- and double-quoted
4427 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4428 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4430 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4432 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4433 This is a corrected version of yesterday's patch.
4435 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4437 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4438 path, too; insert a "===" to emphasize the line.
4440 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4441 ac_cv_build_alias to ac_build_alias.
4442 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4444 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4445 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4446 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4447 (AC_ARG_VAR): ... here.
4448 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4449 target_alias.
4451 Keep a list of all precious variables and process them with one simple
4452 for loop, instead of expanding all commands, or, OTOH, complicated
4453 processing of output of "set".
4454 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4455 variable names in new macro...
4456 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4457 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4458 a loop to assign all ac_env_* and ac_cv_env_* variables.
4459 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4460 to INIT_PREPARE.
4461 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4462 its value to shell variable ac_precious_vars and call
4463 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4464 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4465 _AC_ARG_VAR_VALIDATE.
4467 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4468 and the AC_SUBSTs ...
4469 (AC_INIT): ... here.
4471 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4472 the ac_subst_files section in config.log.
4474 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
4476 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

4480 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
4481 * tests/c.at (C keywords): Test AC_C_TYPEOF.
4483 Fix problems reported by Nicolas Joly.
4484 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
4485 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4486 They are generated by the Tru64 v5.1B shell.
4488 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4490 Fix my changes from 2005-07-01; reported by Noah Misch.
4491 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4492 description, the macro now accepts only a single tag.
4493 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4495 Fix cases when the varsions of Autoconf and Autotest don't match.
4496 Reported by Noah Misch.
4497 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4498 at_top_builddir, for compatibility with older autotest.
4499 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4500 is not set, use at_top_builddir, for compatibility with older
4501 versions of autoconf.
4503 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4505 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4506 Problem reported by Patrick Welche.
4508 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4510 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4511 sed substitution command, so that we allow | in program prefixes
4512 and program suffixes. (& is a problem anyway; we're not fixing
4513 that here.)
4514 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4515 configure_input, top_builddir, srcdir, etc.
4516 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4517 PATH_SEPARATOR in AUTOTEST_PATH.
4519 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4521 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4522 for loop over config.site files using `set', to allow
4523 directory names containing IFS characters.
4525 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4527 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4528 directories with weird names. Apparently some people like living
4529 on the edge. However, improve the test that "pwd" actually does
4530 report a name for the working directory.
4531 * NEWS: Remove the claim that we test for funny chars in dir names.

4545 about #include <config.h>.
4546 (Generic Functions): Mention the Gnulib project.
4547 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4549 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4550 document to output the default config_* lists to config.status.
4551 Don't recognize option --file, if the functionality is not there.
4552 Likewise for --header; moreover, recognize --he and --h as shortcuts
4553 for --help in that case.
4555 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4556 matches the order of execution. No code changed.

4578 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4579 (AC_SUBST): Call it.
4580 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4581 the directory specific variables; but don't call it for configure_input.
4583 2005-06-28 Derek Price <derek@ximbiot.com>
4585 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4586 addition.
4588 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4590 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4591 directory have inherent problems with special characters like spaces,
4592 due to limitations in Make syntax. Problem reported by Alexandre
4593 Duret-Lutz.
4594 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
4595 Also, fix Tru64 porting problem with shell patterns,

4607 from Justace Clutter.
4608 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4609 variable into diagnostic. Make the diagnostic an error, not a warning,
4610 because we really don't support spaces and suchlike in dir names.
4611 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4612 Don't worry about backslashes in srcdir; it can't happen now.
4613 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4614 Simplify ac_optarg handling.
4615 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

4625 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4626 that '\|' is not allowed in BREs; recommend using newline separated
4627 list of patterns instead of multiple -e options.
4629 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4631 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4635 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
4637 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4639 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4640 b, t, r, w commands require single space, while : cannot have any.
4641 (Special Shell Variables): Fix sed code this in the example.
4642 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4643 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4645 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4646 expand to the empty list. Don't use two pairs of m4_changequote,
4647 it's not necessary.
4649 2005-06-20 Derek Price <derek@ximbiot.com>
4651 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4653 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4655 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4656 * doc/autoconf.texi:
4657 Don't mention Solaris versions so much, if a
4658 problem is common to all extant versions of Solaris. Say "SunOS
4659 4" instead of "SunOS" for SunOS 4.
4660 (awk): Mention more of the limitations of traditional Awk.
4661 (cat): Don't talk about cat -v.
4663 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4665 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4666 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
4667 but the implementation is entirely different and is designed
4668 to be compatible with glibc strverscmp.
4669 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4671 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4672 on Mac OS X 10.4 reported by Peter O'Gorman in:
4673 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4674 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4675 Use shell builtins rather than 'expr', to work around expr bug.
4677 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4679 * doc/autoconf.texi: "filesystem" -> "file system".
4680 "behaviour" -> "behavior".

4682 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4683 as per POSIX.
4684 * lib/m4sugar/m4sh.m4: Likewise.
4685 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4686 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4688 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4689 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4690 to update the man page. That way, we don't have to check in new
4691 man pages every month.
4693 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4694 quotes and backslashes. Patch from Derek Price.

4699 AS_TR_SH.
4701 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4703 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4704 -u, since it outputs chatter if the input files are the same.
4705 Problem reported by Ralf Menzel.
4707 2005-06-08 Derek Price <derek@ximbiot.com>
4709 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4710 renaming them since they are about to be redefined anyhow.
4712 2005-06-08 Derek Price <derek@ximbiot.com>
4714 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4715 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4716 Move m4_undefine to alphabetical order.
4718 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4720 * README: Recommend GNU M4 1.4.3 or later.
4721 * doc/autoconf.texi (Introduction): Likewise.
4722 Reword to avoid some formatting glitches.
4723 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4724 Clarify explanation of HP compiler bug.
4725 Redo example output tp match current CVS snapshot.
4726 Use @example.org in email addresses when the examples
4727 might get inadvertently cut-and-pasted into user code.
4728 Remove example of autom4te usage that doesn't seem to work now.
4729 Use modern AC_INIT (except when the example is meant to be
4730 shown with Autoconf 2.13).
4731 Update ksh info for Solaris 9 and later.
4732 KB -> kB.
4733 Modernize description of Automake versions a bit.
4734 Don't claim a future version of Autoconf is near.
4735 * doc/install.texi: Reword to avoid some formatting glitches.
4737 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4739 * doc/autoconf.texi: Add [] to examples, so that the manual
4740 follows its own advice about quoting better.
4741 Reword to avoid some formatting glitches.
4742 * doc/installt.exi: Reword to avoid some formatting glitches.
4744 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4745 Tru64 ksh pattern matching bug. Reported against Libtool by
4746 Albert Chin <libtool@mlists.thewrittenword.com> and
4747 Nicolas Joly <njoly@pasteur.fr>.
4749 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4751 m4_cdr of one-member list was [[]] (one-member list containing an
4752 empty string) instead of [] (an empty list. Callers were skewed to
4753 match this misbehaviour. As a consequence of this:
4754 - m4_foreach([x], [], [foo]) expanded to `foo', while
4755 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4756 This bug has been fixed:
4758 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4759 expand to an empty string; print error msg if called without
4760 an argument list.
4761 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4762 misbehaviour; handle [] and [[]] correctly.
4764 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4766 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

4768 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4770 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4772 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4773 swallow records with more than 99 fields.
4774 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4775 parse the long line.
4777 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4779 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4780 swallow literals longer than 399. Reported by Ralf Wildenhues.
4781 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4782 to workaround this limitation.
4784 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4786 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4787 to gfortran, and make these the first two compiler names
4788 checked (following the general autoconf preference for gcc).
4790 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4792 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4793 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4794 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4796 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4798 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4799 expression of unbounded size when processing the --list
4800 option. This runs afoul of a limit of 399 bytes per regular
4801 expression on AIX. Problem reported by Ralf Wildenhues.
4803 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4805 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4806 * doc/autoconf.texi (Particular Headers): Reword example
4807 for multiline stdbool replacement.
4808 (Setting Output Variables): Reword text a bit. Don't
4809 give all the details about |#_!!_#|.
4810 Reword description of line replacement.
4812 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4814 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4815 now contain newlines, and substituted files must be referenced on
4816 a line alone; the sed scripts to substitute them are now very
4817 different.
4818 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4819 commands can be put in a sed script portably.
4820 * doc/autoconf.texi (Setting Output Variables): Document above
4821 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4822 use of multiline substitution.

4832 * tests/local.at: Don't attempt to check for negated character
4833 classes in shell scripts. The test was too brittle.
4835 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4837 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4838 * doc/autoconf.texi (Limitations of Builtins): Document this
4839 limitation.
4841 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4843 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4844 common code; used in many places in the tree.

4848 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4850 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4851 messages when ac_unique_file is not found.
4852 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4853 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4854 commands, for consistency with AC_MSG_ERROR and such.
4856 * bin/autoconf.as: Make more use of "shift 2" in option processing.

4866 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4868 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4869 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4870 (ac_top_builddir): ... this ...
4871 (ac_top_build_prefix): ... to this; the old name is also kept, for
4872 backward compatibility.
4873 (ac_top_builddir_sub): New variable, without the trailing slash,
4874 always nonempty.
4875 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4876 * doc/autoconf.texi (Configuration Actions): Rename
4877 ac_top_builddir to ac_top_build_prefix.

4887 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4889 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4890 argument to m4_foreach. I guess it was necessary in the past,
4891 but I think it's a no-op now.
4893 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4895 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4896 ``cat <<_ACEOF'' commands to one.
4897 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4898 * lib/autoconf/status.m4: On various places, use expr instead of
4899 ``echo|sed.''
4900 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4901 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4902 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4903 a range.
4904 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4905 the wrong patterns between ``case'' and ``esac.'' The previous
4906 code had false positives.
4908 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4910 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4911 as on 2005-05-02.
4912 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4913 Mention LIBOBJDIR.

4974 * doc/autoconf.texi (Autoconf Language): Be more precise about
4975 quoting rules. Problems noted by Stepan Kasal.
4976 Also, throughout this document, be more careful about white space.
4977 "blank", "white space", and "space" all have different meanings
4978 and we should be careful to say what we mean.

4997 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4998 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4999 set by latest automake.
5001 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
5003 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
5004 outputs 0 on GNU/Linux these days.
5006 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
5008 * doc/autoconf.texi (Autoconf Language): Add more description
5009 about quoting heuristics.
5010 (Limitations of Builtins): Describe "set -" problems.
5012 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5014 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
5015 not newline.
5017 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5018 by AC_DEFINE; it was a mistake.
5019 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
5021 2005-04-25 Stepan Kasal <kasal@ucw.cz>
5023 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
5025 2005-04-22 Stepan Kasal <kasal@ucw.cz>
5027 * doc/autoconf.texi (External Software): Quadrigraphs are not
5028 processed correctly in AS_HELP_STRING; avoid this in the examples.
5029 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5030 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5031 comment and reduce m4_default([foo], []) to [foo].
5032 (m4_strip): Update the explanation.
5034 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5036 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5037 Remove core.conftest.* too; it's generated by Tru64 5.1.
5038 Problem reported by Jennis Pruett.
5039 * lib/autoconf/functions.m4
5040 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5041 Don't bother to remove core files; AC_RUN_IFELSE should do that
5042 for you.
5044 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5046 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

5086 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5088 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5089 Merge `-z option' as well for the benefit of Solaris link flags. Pass
5090 whole-archive (-zallextract, -zdefaultextract) options in the hope of
5091 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5092 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5094 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5096 * NEWS: The configure command now warns you if you attempt to use
5097 a directory whose name contains a special character like space,
5098 newline, or "\".
5099 * doc/autoconf.texi (Installation Directory Variables): Allow
5100 "," in file names. Do not use \@; it's not a portable regexp.
5101 * bin/Makefile.am (edit): Likewise.
5102 * lib/Makefile.am (edit): Likewise.
5103 * tests/Makefile.am (edit): Likewise.
5104 * tests/semantics.at: Likewise.

5106 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
5107 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
5108 * doc/autoconf.texi (File System Conventions): Warn about
5109 unportable file names.
5110 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
5111 (AC_INIT): Use it.
5112 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
5113 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
5114 ac_pwd, and quote srcdir.
5115 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5117 * doc/autoconf.texi: Fix some systematic formatting problems.
5118 ".)" needs a following @: if not at the end of a sentence, and
5119 similarly for "!)". "etc." should be preceded by a comma.
5120 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5122 2005-03-22 Bruno Haible <bruno@clisp.org>
5124 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5125 argument is often called 'build-aux'.
5127 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5129 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5130 macro AC_TRY_LINK is obsolete.
5131 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5132 `AC_CONFIG_FILES'.
5134 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5136 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5137 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5138 from a Common Lisp's `cl'.
5139 (AC_PROG_CXX): Behave according to the documentation: don't
5140 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5141 make the variable CCC precious; use `cl.exe', not `cl'.
5143 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5144 Alexandre Duret-Lutz <adl@gnu.org>
5146 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5147 /dev/null, as "configure" shouldn't read stdin, and this insulates
5148 us from problems (e.g., when testing for "cl"). Also, do this
5149 redirection before invoking "hostname" or "uname", and keep the
5150 original input stream available via...
5151 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5152 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5153 bother with "</dev/null" since it's now done at the top of
5154 'configure'.
5155 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5156 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5157 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

5160 * tests/base.at (Input/Output): New test.
5162 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5164 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5165 newline if neither \c nor -n work, as that would output two
5166 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5168 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5170 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5171 This causes that any required macros inside will get before the if.
5172 * doc/autoconf.texi (autom4te.cache): A typo.
5174 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5176 Undo previous change, except keep the change to
5177 lib/autoconf/programs.m4 that replaced grep with shell
5178 pattern-matching. This is because net-snmp configure reads stdin.
5179 Reported by Noah Misch.
5181 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5183 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5184 from /dev/null, as "configure" shouldn't read stdin, and this
5185 insulates us from problems (e.g., when testing for "cl").
5186 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5187 before invoking "hostname" or "uname".
5188 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5189 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5190 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5191 "</dev/null" since it's now done at the top of 'configure'.
5192 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5193 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5194 Also, replace grep with shell pattern-matching, to save a process.
5196 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5198 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5199 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5200 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5201 compiler.
5203 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5205 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5206 grep -q isn't portable. Improve grep -s explanation.
5207 Problem reported by Dan Manthey.
5209 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5211 * doc/autoconf.texi (Special Shell Variables): Clarify
5212 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5214 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5216 * doc/autoconf.texi: Use @acronym for DJGPP.
5217 Fix some @code's that should have been @env's, and vice versa.
5218 Sort environment variable names.
5219 Mention that shells no longer inherit IFS.
5220 Don't recommend PATH_SEPARATOR=';' so strongly.
5221 Mention that $RANDOM might expand to the empty string.
5222 "symlink" and "soft link" -> "symbolic link".
5223 Improve mktemp description (reported by Bruno Haible).
5225 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5227 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5228 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5229 Likewise.
5230 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5231 Likewise.
5233 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5235 * NEWS: Mention AT_COPYRIGHT.
5237 * tests/local.at (AT_CMP): Use diff directly on input files rather
5238 than copying them.
5240 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5241 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5243 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5244 and Paul Eggert <eggert@cs.ucla.edu>
5246 * tests/autotest.at (Empty test suite): New test.

5248 (Substitute a 2000-byte string, Define to a 2000-byte string)
5249 (Substitute a newline, Define a newline): New tests.
5251 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5253 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5254 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5255 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5256 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5257 (Standard regular expressions): New test.
5258 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5259 excess test name quoting.
5260 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5261 CPPFLAGS to `configure' instead of setting it in `configure'.
5263 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5264 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5265 on some platforms.
5267 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5268 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
5270 * tests/local.at (AT_CMP): New macro.
5271 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
5272 (AC_SAVE_STATE): Move environment grep...
5273 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
5274 (AT_CONFIG_CMP): New macro.
5275 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
5276 * tests/c.at (Extensions): Do not exit early.

5279 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
5280 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
5282 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
5283 (AC_COPYRIGHT): Factor header comment portion out and move into...
5284 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
5285 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
5286 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
5287 --version output.

5294 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
5296 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
5298 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5299 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5301 Try not to generated lines of unlimited length, as POSIX places a
5302 2047-byte limit on line length of portable text files.
5303 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5304 Use newline as a separator, not space.
5305 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
5306 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
5307 space.
5309 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5311 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
5312 as_func_*. Add test to check whether positional parameters
5313 are restored after function return.
5315 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
5317 * doc/autoconf.texi (Special Shell Variables): Mention _,
5318 BIN_SH, DUALCASE. Say that variables other than "status" are safe
5319 if they contain a lower-case letter. The DUALCASE problem was
5320 reported by Ralf Wildenhues.
5322 * bin/autoconf.as: Don't exit with status 0 after write failure
5323 with --help or --version.
5324 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
5325 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

5329 * doc/autoconf.texi (Limitations of Usual Tools):
5330 Unicos 9 sed limitations.
5331 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
5332 to get the option-enhanced interface on older Crays. Try ftn for
5333 Fortran 95 (newer Crays).
5335 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
5337 * man/Makefile.am (.x.1): Go back to the simple solution, but take
5338 care to echo the commands, so the user knows what's going on.
5339 Modified from a suggestion by Stepan Kasal.
5341 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
5342 with a cross reference. Derived from a suggestion by Bruce Korb.
5344 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
5346 * doc/autoconf.texi (config.status Invocation): Warn about
5347 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
5348 * doc/install.texi (Defining Variables): Likewise.
5349 Based on a proposed patch by Ralf Wildenhues.
5351 * man/Makefile.am (.x.1): Make sure the required generated files
5352 are up to date. Problem and original solution proposed by Stepan Kasal.
5353 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
5354 implicit-man-prerequisites): New rules, used by the above.
5356 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.
5357 * config/config.guess, config/config.sub, config/install-sh: Likewise.

5360 2005-01-29 Stepan Kasal <kasal@ucw.cz>
5362 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5363 Update the long comment explaining it.
5365 m4_require no longer writes an ``is required by'' line to the
5366 execution stack. It contains only one bit of non-redundant
5367 information: that the macro was required, not called. And even
5368 this bit is useless in most situations: have you ever met a macro
5369 which both calls and requires the same macro?
5371 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5372 (_m4_defun_pro_outer): ... only via this macro, for the outermost
5373 macro.
5374 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
5375 (m4_expansion_stack_pop): Remove the misplaced comment.
5376 (m4_require): Don't put the ``is required by'' line to the
5377 execution stack; slightly improve the out-of-a-defun error message.
5378 (_m4_divert_grow): New macro, counter for the temporary diversions.
5379 (_m4_require_call): Use it.
5380 * tests/m4sugar.at (m4_require): Expect output without the
5381 ``is required by'' messages.
5383 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5385 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5386 rather than x for expr.
5388 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5389 this is safe.
5390 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
5391 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

5396 2005-01-27 Akim Demaille <akim@epita.fr>
5398 Have autoheader honor --force.
5400 * doc/make-stds.texi, doc/standards.texi: Update from masters.
5401 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
5402 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
5403 from masters, so that FileUtils.pm's update_file provide --force
5404 support.
5405 * bin/autoheader.in: Pass $force to update_file so that
5406 config.h.in is always recreated when --force.
5408 2005-01-24 Stepan Kasal <kasal@ucw.cz>
5410 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
5412 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
5414 * doc/autoconf.texi (Limitations of Builtins): Clarify that
5415 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
5417 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5419 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5420 Warn about newline stripping in `` and $(). Update Solaris
5421 version to 9.
5422 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5423 X insulates us from future changes to Posix.
5424 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
5425 stripping.

5791 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5792 "char c = '\200';" rather than "char c = 0x80;" as the

5895 * doc/autoconf.texi (auindex): New macro.
5896 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
5897 Problem reported by Stepan Kasal.
5899 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>

5903 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5904 in test makefile.
5905 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
5906 readable; it's not true in OS/2-emx.
5908 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5910 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5911 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5912 (trivial change). Problem and patch reported by Andrew Church in:
5913 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5915 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

5920 Also, fix some minor spacing and punctuation bugs.
5922 2004-09-02 Akim Demaille <akim@epita.fr>

5942 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5943 texinfo.tex for now (done by hand now).
5944 * Makefile.maint (wget_files, cvs_files):
5945 Remove ansi2knr.c; nobody uses it.
5946 (ansi2knr.c-url_prefix): Remove.
5947 (cvs-update): Fix test for failure. I don't know why it ever
5948 worked...
5950 * doc/autoconf.texi: Update URLs, some of which went stale.
5951 Use @uref rather than @href.
5953 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5954 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5956 * config/config.guess, config/config.sub, config/elisp-comp,
5957 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5958 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5960 * NEWS, TODO, configure.ac, bin/autoscan.in,
5961 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5962 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5966 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5967 tests/tools.at, tests/torture.at:
5968 Use "file name" rather than "filename" or "path",
5969 to be consistent with the terminology of the GNU coding standards.
5971 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5973 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5974 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5975 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5976 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5978 More fixes to support spaces in the name of the build directory.
5979 This isn't a complete fix but it's an improvement.
5981 * bin/autoconf.as (autom4te_options): New var.
5982 Use it instead of appending to AUTOM4TE, so that we can allow
5983 spaces in the build directory's absolute name.
5984 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5985 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5986 AT_CHECK_NOESCAPE): Likewise.
5987 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5988 main program): Likewise.
5990 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5992 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
5993 From Ralf Corsepius in:

5996 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5998 * doc/autoconf.texi (Function Portability): Document isinf and
5999 and isnan. From a suggestion by Kevin Ryde.
6001 * lib/Autom4te/General.pm (END): Return correct exit status even
6002 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
6004 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
6006 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
6007 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
6008 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
6010 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
6012 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
6013 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
6014 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
6015 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
6016 * lib/autom4te.in (Automake-preselections): Preselect
6017 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
6019 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
6021 * lib/autom4te.in (Automake-preselections): Preselect
6022 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
6023 trace them.
6025 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
6027 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6028 Tru64.
6029 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6030 Document problem with "`""`" in pdksh POSIX mode.
6032 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6034 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6035 with pdksh, too. Problem reported by Patrick Welche via
6036 Gary V. Vaughan.
6037 * doc/autoconf.texi (Shellology): Note that set -o posix is
6038 useful for pkdsh, too.
6040 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6042 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6043 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6044 Don't fail if ENV or BASH_ENV is readonly.
6045 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6046 etc. are read only. Problem reported by Ludovic Courtes.
6048 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6050 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6051 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6052 (trivial change)
6054 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6056 * doc/autoconf.texi (File System Conventions): Warn about
6057 names like "aux". Problem reported by Eric Blake.
6059 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6060 by zero instead of array size, so that we can use any arithmetic
6061 constant expression (instead of requiring an integer constant
6062 expression). This allows us to test expressions like DBL_MAX <
6063 LDBL_MAX, which didn't conform to the C standard using the old
6064 method.
6065 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6066 now that we can do floating-point tests at compile time.
6068 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6070 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6071 and LDBL_EPSILON, as the resulting expression isn't an
6072 integer constant expression and violates the C standard.
6073 Problem reported by Nelson H. F. Beebe. Also, check
6074 for "L" suffix, and check that long double doesn't have
6075 worse range or precision than double, that mixed-mode
6076 arithmetic doesn't generate a diagnostic, that double
6077 constants fit in long double.
6079 2004-06-03 Kevin Ryde <user42@zip.com.au>
6081 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6082 malloc(0) and realloc(NULL,size).
6084 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6085 Bob Proulx.
6087 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6089 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6090 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6091 by Jim Meyering.
6093 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6095 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6096 can be rewritten using if-then-else. Suggested by Bruno Haible.
6098 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6100 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6101 Problem reported by Stepan Kasal.
6103 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6105 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6106 change). Patch reported by Ralf Wildenhues in
6107 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6109 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6110 function F exists if the compiler and linker let you compile an
6111 expression like (F != 0). Recent versions of GCC optimize away
6112 the reference to F in that case, since every function address must
6113 be nonzero, so the link succeeds even if F does not exist.
6114 Problem reported by Manu in
6115 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6117 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6118 "Unix". Many uses changed.
6119 (Limitations of Builtins): Explain better why the ! command isn't
6120 portable.
6122 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6124 * lib/autom4te.in (Automake-preselections): Preselect
6125 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6127 2004-05-19 Kevin Ryde <user42@zip.com.au>
6129 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6130 referencing AC_FUNC_STRERROR_R.
6132 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6133 note pessimistic assumption when cross compiling.
6135 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6137 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6138 (until 2004) invoked subcommands with sh -e, contra POSIX.
6139 Reported by Kevin Ryde.
6141 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6143 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6144 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6145 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6146 `test -f " /usr/bin/grep"', which _always_ failed.
6147 (AC_PROG_SED): Ditto bogus PATH fix.
6148 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6149 requires that grep correctly supports _multiple_ `-e' options, rather
6150 than stating only that grep should accept `-e'.
6152 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6154 Port to C99, which requires that 'exit' be declared.
6156 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6157 to ensure that stdlib.h is included.
6158 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6159 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6160 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6161 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6162 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6163 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6164 when using 'exit' in a test; C99 requires that 'exit' be declared.
6166 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6168 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6169 now prefers 'grep' implementations that accept -e.
6170 (Limitations of Usual Tools): Describe problems of traditional
6171 egrep and fgrep with long input lines, and of traditional grep
6172 with -e.
6173 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6174 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6175 All callers changed. Append /usr/xpg4/bin to the PATH, for
6176 Solaris.
6177 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6178 the user with complaints about multiple -e options.
6179 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6180 Define it with AC_PROG_GREP.
6181 * configure.ac (AC_PROG_GREP): Add.
6182 * lib/freeze.mk (GREP): New macro.
6184 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6186 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6187 a possible candidate only after all others fail, rather than
6188 consulting it first. This improves backward compatibility by
6189 better reflecting the way shell selection occurred in previous
6190 versions of Autoconf, and should help to avoid triggering latent
6191 problems in other packages, such as the one in Automake where zsh
6192 is not handled robustly:
6193 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6194 Although it is not Autoconf's responsibility to work around
6195 problems in Automake, it nevertheless makes sense to avoid
6196 introducing unnecessary incompatibilites.
6198 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6199 Gary V. Vaughan <gary@gnu.org>
6201 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6202 how deeply nested we are when a suitable tool is found, set the
6203 ac_path_TOOL_found flag.
6204 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6205 nested we are in this macro. Break out of all 3 nested loops if
6206 ac_path_TOOL_found is set.
6208 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6210 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6211 of the _AS_PATH_WALK loop too if GNU flavor is found.
6213 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6215 * doc/autoconf.texi (Limitations of Make): Update documentation
6216 for `$<'. New entry `Long lines', based on a report from Simon
6217 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6218 paragraph about DJGPP, based on a mail from Richard Dawe.
6220 2004-04-20 Paul Eggert <eggert@twinsun.com>
6222 * tests/c.at (C keywords): Don't assume that GCC supports
6223 "restrict" and "inline", as sufficiently-old GCC versions do not
6224 (also, GCC configured to be in pedantic C89 mode does not).
6225 Problem reported by Sumit Pandya in:
6226 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6228 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6229 consider -g to work if it generates warnings when plain compiles
6230 don't. Problem reported by Braden McDaniel in:
6231 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6233 * doc/autoconf.texi (Slashes): New section, to document a problem
6234 reported by Jim Meyering in:
6235 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6237 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6238 linker output files before linking, to work around IRIX 6 linker bug.
6239 Problem reported by Rainer Orth in:
6240 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6242 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6244 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6245 best tool so far counter rely on the tool path variable name to
6246 avoid checks for one tool being affected by the results of running
6247 the length check on a previous tool.
6249 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6250 match expression argument, as different greps have different
6251 regular expression flavours.
6252 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6253 literals.
6254 (AC_PROG_EGREP): Pass 'EGREP$'.
6255 (AC_PROG_GREP): Pass 'GREP$'.
6257 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6259 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6260 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6262 2004-03-29 Paul Eggert <eggert@twinsun.com>
6264 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6265 Types, Specific Compiler Characteristics, System Services,
6266 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6267 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6268 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6269 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6270 Likewise.
6271 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
6272 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
6273 AC_TYPE_OFF_T): Likewise.
6274 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
6275 Likewise.
6277 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
6278 pacify libtool 1.5.2. Fix quoting problems in sed command.
6280 2004-03-28 Paul Eggert <eggert@twinsun.com>
6282 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6283 now defines HAVE_DECL_TZNAME if it is declared, when
6284 HAVE_STRUCT_TM_TM_ZONE is not defined.
6285 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6286 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6287 for HAVE_TZNAME.
6289 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
6291 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
6292 superfluous backslashing of quotes (") in sed expressions;
6293 thanks to Paul Eggert.
6295 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6297 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6298 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6299 H. F. Beebe for the bug report.
6301 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6303 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6304 quoted -cmdline argument in Portland Group compiler (bug
6305 reported by Jeffrey J. Barteet).
6307 2004-03-25 Kevin Ryde <user42@zip.com.au>
6309 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
6310 (Run Time): ... here, where it's now mentioned.
6312 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
6314 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
6315 inherits from language Autoconf-without-aclocal-m4.
6316 (Customizing autom4te): Adjust example; the cache must now be
6317 disabled for language Autoconf-without-aclocal-m4.
6319 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
6320 Nathanael Nerode <neroden@twcny.rr.com>
6322 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
6323 AC_CHECK_TOOLS): Warn if a cross-tool is found without
6324 a prefix.
6325 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
6326 AC_CHECK_TARGET_TOOLS): New macros.
6327 * doc/autoconf.texi (Generic Programs): Document
6328 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
6329 AC_CHECK_TARGET_TOOLS, and warn for future changes
6330 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
6331 AC_CHECK_TOOLS.
6332 (Specifying Names): Document the reason for these future
6333 behavioral changes.
6334 * tests/mktests.sh: Do not generate tests for the
6335 new macros.
6336 * NEWS: Document these changes.
6338 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6339 they make TeX hang up.
6341 2004-03-15 Paul Eggert <eggert@bogus.example.com>
6343 * NEWS: New macro AC_CHECK_ALIGNOF.
6344 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6345 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6346 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6347 vowel.
6348 (AC_CHECK_ALIGNOF): New macro.
6349 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
6350 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
6351 those for sizeof.
6353 2004-03-03 Paul Eggert <eggert@twinsun.com>
6355 * bin/Makefile.am (edit): Don't use $< in a context where
6356 POSIX doesn't require support for it. Use $@.in instead.
6357 Problem reported by Anthony N. Frasso in
6358 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6359 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
6361 2004-02-23 Gary V. Vaughan <gary@gnu.org>
6363 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
6364 from the next generation of Libtool.
6365 * lib/autom4te.in (Autoreconf-preselections): Ditto.
6367 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6369 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
6370 is not always thread-safe. Report from Nathanael Nerode.
6372 2004-02-18 Paul Eggert <eggert@twinsun.com>
6374 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6375 problem on QNX reported by Stephen Rasku in
6376 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6378 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6379 $(m4sh_m4f_dependencies); this removes a FIXME.
6380 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6381 (MAINTAINERCLEANFILES): Split into pieces,
6382 one per related section. Add $(srcdir)/wrapper.in.
6384 2004-02-09 Paul Eggert <eggert@twinsun.com>
6386 * doc/autoconf.texi (Setting Output Variables): Emphasize that
6387 AC_SUBST provides no portable way to escape literal newlines.
6389 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6390 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6391 Darwin uses -lcrt2.o and there's little point to cataloging all
6392 the system variants. Partial fix reported by Andreas Waechter in:
6393 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
6394 for bug reported by Nelson H. F. Beebe in:

6397 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
6399 * doc/autoconf.texi (AU_DEFUN): Fix English,
6400 suggested by Paul Eggert.
6401 * lib/autoconf/autoupdate.m4: Correct reference to
6402 acobsolete.m4, suggested by Alexandre Duret-Lutz.
6404 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
6406 * bin/autoupdate.in: Define __file__ so that warnings
6407 refer to the correct file.
6408 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
6409 the behavior of the third argument.
6410 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6411 correctly the behavior of the third argument. Document
6412 what the three macros that AU_DEFUN defines do. Fix
6413 warning message when the third argument includes $0
6414 (reported by Alexandre Duret-Lutz).
6416 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6417 Eric Sunshine <sunshine@sunshineco.com>
6418 Paul Eggert <eggert@twinsun.com>
6420 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
6421 (AS_INIT): Output shell initialization there. Removed optional
6422 parameter. Expand _AS_SHELL_FN_SPY.
6423 (AS_INIT_WITH_SHELL_FN): Removed.
6424 (_AS_SHELL_FN_SPY): New macro.
6425 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
6426 macros.
6427 (AS_SHELL_SANITIZE): Remove loop to find better shell
6428 and documentation for the parameter.
6429 (_AS_DETECT_BETTER_SHELL): Move it here.
6430 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
6431 (_AS_RUN): Move it here, support testing with eval.
6432 (AS_REQUIRE_SHELL_FN): Require shell functions when
6433 it is used.
6434 (_AS_LINENO_WORKS): Put around braces, we do not
6435 trigger the bash bug anymore.
6436 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
6437 use AS_INIT_WITH_SHELL_FN.
6438 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6440 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6442 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
6443 * doc/autoconf.texi: Don't say that the third parameter
6444 is broken.
6445 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
6446 (AU_DEFUN): Honor the third parameter, create autoupdate
6447 macros with AU_DEFINE.
6448 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
6449 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
6450 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
6451 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
6452 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
6453 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,
6454 AC_XENIX_DIR): Likewise.
6455 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
6456 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
6457 * lib/autoconf/status.m4: Remove FIXME.
6458 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
6459 that the macro is not present anymore in the updated
6460 configure.ac.
6461 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
6462 of autoupdate.
6464 2004-01-28 Paul Eggert <eggert@twinsun.com>
6466 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
6467 copyright years.
6468 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6469 2003 (except 1997) to the list of copyright years. This undoes
6470 the 2003-05-22 change, which removed the older years from the list.
6471 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6473 2004-01-27 Gary V. Vaughan <gary@gnu.org>
6474 Albert Chin-A-Young <china@thewrittenword.com>
6476 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
6477 grep or ggrep program in PATH that accepts as long lines as
6478 possible.
6479 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
6480 AC_PROG_GREP.
6481 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
6482 egrep and fgrep respectively if $GREP -E/-F don't work.
6483 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6484 _AC_PROG_GREP, and AC_PROG_SED.
6485 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6486 longest input length accepted by a command.
6487 (AC_PROG_SED): Use it.
6488 * doc/autoconf.texi (Particular Programs): Document the changes.
6489 * NEWS: Updated.
6491 2004-01-27 Paul Eggert <eggert@twinsun.com>
6493 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
6494 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6495 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
6496 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
6498 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6499 bin/autoconf.in, config/Makefile.in, config/config.guess,
6500 config/config.sub, config/install-sh, config/mdate-sh,
6501 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,
6502 lib/Makefile.in, lib/Autom4te/Makefile.in,

6511 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
6512 tests/actypes.at: Regenerate and/or sync with original
6513 sources.
6515 2004-01-26 Paul Eggert <eggert@twinsun.com>
6517 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6518 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6519 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6520 not <inttypes.h>. Problem reported by Tim Mooney in
6521 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6522 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6523 Likewise.
6525 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6526 otherwise "make check" fails because it forbids cmp (I guess
6527 because cmp treats files as binary on DOS-like systems).
6529 * tests/mktests.sh: Update copyright date to 2004, since some tests
6530 have changed in 2004.
6532 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6534 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6535 non-truncating sed or gsed program in PATH.
6536 * tests/acprograms.at: Add it.
6537 * doc/autoconf.texi (Particular Programs): Document it.
6538 * NEWS: Updated.
6540 2004-01-15 Paul Eggert <eggert@twinsun.com>
6542 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6543 -std1 disables some useful extensions on Tru64. Problem reported
6544 by N. Lichtmaier in
6545 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6547 2004-01-14 Paul Eggert <eggert@twinsun.com>
6549 * doc/autoconf.texi (Programming in M4sh): Document that
6550 AS_MKDIR_P succeeds if the destination is a symbolic link
6551 to an existing directory.
6552 (Limitations of Usual Tools): Note that mkdir -p might not
6553 succeed on symlinks to directories.
6555 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6557 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6558 * bin/autoheader.in: Grammar fix in message.
6559 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6560 Test for dir before calling mkdir -p. (trivial changes)
6562 2004-01-13 Eric Blake <ebb9@byu.net>
6564 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6565 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6567 2004-01-10 Jim Meyering <jim@meyering.net>
6569 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6571 2004-01-09 Paul Eggert <eggert@twinsun.com>
6573 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6574 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6575 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6576 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6577 AC_COMPILE_IFELSE, since we now assume our caller invokes
6578 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6579 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6580 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6581 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6583 2004-01-07 Paul Eggert <eggert@twinsun.com>
6585 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6586 `"'...'"`, as it's confusing (and I suspect it may not work on
6587 some platforms). The code was incorrect anyway, as it assumed
6588 that \$ evaluated to itself in that context. Reported by
6589 Alexandre Duret-Lutz.
6591 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6593 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6594 and _LT_AC_TAGCONFIG.
6596 2004-01-06 Paul Eggert <eggert@twinsun.com>
6598 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6599 example, and add more examples. Reported by Eric Sunshine.
6601 2004-01-05 Paul Eggert <eggert@twinsun.com>
6603 * doc/autoconf.texi (Limitations of Usual Tools):
6604 Remove warning against "rm -fr" introduced yesterday; it
6605 was a false alarm.
6607 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6608 autoscan, autoupdate, ifnames): Don't use chmod -w.
6609 * lib/Makefile.am (autom4te.cfg): Likewise.
6610 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6611 "chmod -w".
6613 2004-01-04 Paul Eggert <eggert@twinsun.com>
6614 Paolo Bonzini <bonzini@gnu.org>
6616 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6617 by doing lineno substitution only on lines containing "$LINENO".
6619 2004-01-04 Paul Eggert <eggert@twinsun.com>
6621 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6622 Use "rm -f" to remove conftest.sed, not plain "rm".
6623 Bug reported by David Relson in
6624 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6626 * Makefile.am (autom4te-update):
6627 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6628 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6629 * doc/autoconf.texi (Guidelines): Likewise.
6630 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

6634 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
6635 * tests/Makefile.am (clean-local): Likewise.
6636 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6637 srcdir): Likewise.
6638 * doc/autoconf.texi (Limitations of Usual Tools):
6639 Warn against "rm -fr".
6641 2004-01-03 Paul Eggert <eggert@twinsun.com>
6643 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6644 -c -o might not work. From a suggestion by Kevin Ryde.
6645 (C Compiler, Generating Sources, Limitations
6646 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6647 Don't put '-o' after non-options, as POSIX doesn't allow this.
6648 Mention that cc's name might be gcc or c89 or whatever.
6650 2004-01-04 Kevin Ryde <user42@zip.com.au>
6652 * doc/autoconf.texi: Add various further index entries.
6654 2003-12-29 Paul Eggert <eggert@twinsun.com>
6656 * bin/autoreconf.in (autoreconf_current_directory):
6657 Fix typo: mkdir without umask arg.
6659 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6661 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6662 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6663 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6664 explanation clearer.
6666 2003-12-24 Andreas Schwab <schwab@suse.de>
6668 * doc/autoconf.texi (Default Includes): Fix misspelling of
6669 AC_INCLUDES_DEFAULT.
6671 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6673 * configure.ac: Test if sh -n works.
6674 * configure: Regenerate.
6675 * tests/atlocal.in: Store the result here.
6676 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6677 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6678 of explicitly testing.
6679 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6680 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6681 * tests/tools.at (Syntax of the shell scripts): Simplify
6682 using AT_CHECK_SHELL_SYNTAX.
6683 (Syntax of the Perl scripts): Remove definition of
6684 AT_CHECK_PERL_SYNTAX.
6686 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6688 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
6689 stderr to /dev/null.
6690 * bin/autoconf.in: Regenerate.
6691 * bin/wrapper.in: Regenerate.
6693 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
6695 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
6696 Extracted from AS_SHELL_SANITIZE.
6697 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6698 macros.
6699 (AS_SHELL_SANITIZE): Move reinvocation code from
6700 _AS_LINENO_WORKS, use it to find out if shell
6701 functions work.
6702 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6703 does not work.
6704 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6705 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
6706 was called.

6715 * config/announce-gen (&print_locations, &print_signatures)
6716 (&sizes): New.
6717 Use them.

6719 them on the fly.
6721 2003-11-24 Akim Demaille <akim@epita.fr>
6723 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6751 parameter of AU_DEFUN.
6752 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

6754 Use AC_DEFUN directly, not AU_DEFINE.
6755 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
6756 the expanded body, consistently with other macros such as AC_USG.
6758 2003-11-17 Paul Eggert <eggert@twinsun.com>
6760 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
6761 into the initial confdefs.h, to work around a bug in NextStep 3.3
6762 patch 3 reported by Eric Sunshine.
6764 2003-11-15 Kevin Ryde <user42@zip.com.au>
6766 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6767 than $target since the latter is not usual, add guidelines on when to
6768 use or not use the system type.
6770 2003-11-12 Derek Price <derek@ximbiot.com>
6772 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
6773 typo misrepaired by an auto-spellcheck.
6775 2003-11-12 Akim Demaille <akim@epita.fr>

6925 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
6927 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
6928 cross test.
6930 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
6932 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
6933 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

6944 Issue a more-informative diagnostic.
6945 Problems reported by Eric Sunshine.
6947 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6949 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6950 -mGLOB_options_string stuff for Intel ifc, which can cause

6960 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
6961 that future autopoint/aclocal/automake/autoreconf will be able

6970 -lcrt[01].o.
6972 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
6974 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6975 cache variable instead of $G77 to decide whether to include -O2,
6976 since $G77 is specific to Fortran 77.

6980 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6981 free" flag. Re-order flags tested into rough order of popularity.
6983 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6985 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6986 arguments so that it can be used with syntax identical to
6987 AC_PROG_F77, and so that we can more easily decide to
6988 remove/deprecate the DIALECT optional argument in the future if it
6989 proves troublesome.
6990 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6991 non-freeform-supporting compilers. Document freeform flags.
6993 2003-10-03 Akim Demaille <akim@epita.fr>
6995 * configure.ac: Look for emacs, not macs.

7005 2003-10-03 Akim Demaille <akim@epita.fr>
7007 * configure.ac: Quotation and formatting changes.

7054 Problem reported by Lars J. Aas in
7055 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
7056 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7057 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7058 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7060 2003-09-26 Akim Demaille <akim@epita.fr>
7062 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7063 directory for AC_CONFIG_COMMANDS' first argument exists.
7064 This makes valid the invocation of _AC_SRCPATH that follows.
7065 Reported by Eric Sunshine.
7066 * doc/autoconf.texi (Configuration Commands): Adjust.
7068 2003-09-26 Akim Demaille <akim@epita.fr>
7070 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7071 Reported by Ralf Corsepius.

7075 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
7076 arguments.
7077 Actually, use AU_ALIAS.
7078 From Bruno Haible.

7089 The test suite are sometimes assigning timings incorrectly.
7090 Reported by Henk Krus.
7091 Diagnosed by Nicolas Joly.
7093 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7094 AT_help_all.
7095 Instead of making AT_help a sequence of assignments to grow
7096 $at_help_all, just make AT_help_all be the growing contents of
7097 $at_help_all, and make a single assignment in...
7098 (AT_INIT): here.
7099 (at_times_skip): Flip the meaning and rename as...
7100 (at_times_p): this.
7101 (AT_INIT): When summarizing the test that ran, remove
7102 $at_times_file after use, and check it is present before trying to
7103 use it.
7105 2003-09-25 Akim Demaille <akim@epita.fr>
7107 Version 2.57d.

7111 (ifnames): chmod -w.
7112 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7113 executables, not bin/ executables! Otherwise all the magic needed
7114 to find non installed files is turned off. This caused a failure
7115 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7116 as found in its environment (sent by tests/autoreconf): pointing
7117 to bin/autom4te that could not find its files.
7118 * tests/mktests.sh: Force the replacement of generated files, for
7119 the sake of "mv" program that are interactive when overwriting a
7120 -w file.
7121 * config/install-sh: Upgrade from CVS Automake.
7123 2003-09-23 Paul Eggert <eggert@twinsun.com>

7126 versus test -L issues.
7128 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
7129 Paul Eggert <eggert@twinsun.com>
7131 Trivial change to support GCC's configuration procedure.
7132 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
7133 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
7134 about inconsistency if the preprocessor is set to give errors for
7135 any warning.
7136 * doc/autoconf.texi (C Compiler Characteristics): Document this.
7138 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
7140 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
7141 and XFile.pm from Automake.

7159 2003-09-11 Akim Demaille <akim@epita.fr>
7161 * doc/autoconf.texi (Header Portability): linux/random.h.
7162 From Peter Hendrickson.
7164 2003-09-10 Akim Demaille <akim@epita.fr>
7166 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
7167 willing to edit the output files.
7169 2003-09-10 Akim Demaille <akim@epita.fr>
7171 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
7172 and AC_FC_FREEFORM.
7173 * tests/mktests.sh: Skip AC_FC_SRCEXT.
7174 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
7176 2003-09-09 Akim Demaille <akim@epita.fr>

7190 Improve the accuracy of the wording about obsolescence.
7191 From a suggestion by Ian Lance Taylor in
7192 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
7194 2003-09-05 Paul Eggert <eggert@twinsun.com>
7196 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
7197 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
7199 2003-09-04 Akim Demaille <akim@epita.fr>
7201 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
7202 AC_FUNC_WAIT3.
7204 2003-09-04 Akim Demaille <akim@epita.fr>
7206 * bin/autom4te.in: Use &fatal where more appropriate than &error.
7207 (freeze): When exiting, use $exit_code.

7212 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7214 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7216 Add support for newer Fortran dialects. The F77 interface is
7217 unchanged, and continues to support Fortran 77. New FC macros
7218 correspond to all the old F77 macros, with output variables FC,
7219 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7220 available dialect, but older dialects can be specified. There are
7221 new macros AC_FC_SRCEXT to set the source extension, and
7222 AC_FC_FREEFORM to accept free-form source files.
7224 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
7225 New macros.
7226 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

7242 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
7243 Rewrite in terms of the above.
7244 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
7245 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

7251 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
7252 Document problems with timestamp resolution that 'make', 'cp -p', and
7253 'touch -r' have.

7257 * tests/m4sugar.at (cross_warning): Make sure to enable the
7258 output, so that we can track spurious m4sugar output.
7259 * tests/local.at: Require 2.57.
7260 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7261 are defaulted by AT_CHECK anyway.
7262 Use AT_CHECK_AUTOM4TE.
7263 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7264 missing dnl.
7266 2003-08-27 Akim Demaille <akim@epita.fr>
7268 * bin/autoheader.in: Issue the "Using auxiliary..." message only
7269 when -Wobsolete is set.
7270 Set it on by default.
7271 Suggested by Klee Dienes.
7273 2003-08-27 Akim Demaille <akim@epita.fr>
7275 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
7276 documentation.
7277 From Guido Draheim.
7279 2003-08-26 Akim Demaille <akim@epita.fr>
7281 * doc/autoconf.texi (Output): Make clear that one can run code
7282 after AC_OUTPUT.
7284 2003-08-25 Akim Demaille <akim@epita.fr>
7286 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
7287 CVS Bison.
7289 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
7291 * bin/autoreconf.in (parse_args): Do not pass --no-force to
7292 Automake versions prior to 1.8.
7294 2003-08-25 Akim Demaille <akim@epita.fr>

7301 * configure.ac: Bump to 2.57c.
7303 2003-08-22 Akim Demaille <akim@epita.fr>
7305 Version 2.57b.
7307 * Makefile.cfg (local-checks-to-skip): New.
7308 * Makefile.maint (local-check): Rename as...
7309 (local-checks-available): this.
7310 (local-check): New.
7312 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
7313 * configure.ac: Require Automake 1.7.6.
7315 2003-08-22 Akim Demaille <akim@epita.fr>
7317 Output stack traces in warnings.
7319 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
7320 Replace the former...
7321 (m4_warn): Pass the call stack to _m4_warn.
7322 * bin/autom4te.in: Adjust to output the call stack.
7323 * tests/m4sugar.at (m4@&t@_warn): Adjust.
7325 2003-08-22 Akim Demaille <akim@epita.fr>
7327 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
7328 * bin/autom4te.in: Adjust.
7330 2003-08-21 Akim Demaille <akim@epita.fr>
7332 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7333 (&verbose): Remove.
7334 (&getopt): Adjust the note and verb channels, depending upon
7335 --verbose.
7336 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
7337 * bin/autoupdate.in: Adjust.
7338 Use &verb, not &verbose.
7340 2003-08-21 Akim Demaille <akim@epita.fr>
7342 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7343 &parse_WARNINGS.
7344 ($help): Use Autom4te::ChannelDefs::usage.
7345 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7346 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7348 2003-08-21 Akim Demaille <akim@epita.fr>
7350 First stab at preserving warnings between calls to autom4te,
7351 including when the cache is used.
7353 There are still several issues: (i) there are too many runs of m4
7354 (one for include, one for warnings, and some more), (ii) warnings
7355 spreading on several lines are not handled gracefully, (iii) the
7356 code meant to have the call stack display for errors does not work
7357 (its handling should move from m4 to autom4te).
7359 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7360 Use them.
7361 (@preselect): Add m4_warn.
7362 ($exit_status): Remove, use $exit_code.
7363 ($help): Use Autom4te::ChannelDefs::usage.
7364 (&handle_m4): No longer define the m4_warnings.
7365 At each run, extract and report the warnings.
7366 Always cache the result, including if the exit status is on
7367 failure, since if nothing changes, we should result in the same
7368 failure, hence we can use the cache.
7369 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7370 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7371 Remove.
7372 (m4_warn): Redefine as a do-nothing: it is its invocation that
7373 matters, as warnings are now reported via traces.
7374 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7375 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7376 the latter reveals calls to the former.
7378 Adjust the tests.
7380 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7382 2003-08-21 Akim Demaille <akim@epita.fr>
7384 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7385 Use them.
7387 2003-08-21 Akim Demaille <akim@epita.fr>
7389 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7390 forward order.
7391 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7392 (&parse_warnings): Accept a list of warning requests.
7393 (&usage): Return a string, not a side effect.
7394 (cross): New warning category.
7396 2003-08-21 Akim Demaille <akim@epita.fr>
7398 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7399 (&require_configure_ac): Accept an optional directory argument.
7400 ($configure_ac): Remove.
7401 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7402 (&catfile): Remove.
7403 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7404 * bin/autoscan.in: Adjust.
7406 2003-08-20 Akim Demaille <akim@epita.fr>
7408 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7409 Reported by Alexandre Duret-Lutz.
7411 2003-08-20 Akim Demaille <akim@epita.fr>
7413 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7414 * bin/autom4te: Adjust.
7415 In particular, be Autoconf tools are really silent when properly
7416 working, bind the verbosity of the 'note' channel to $verbose.
7417 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7418 (&xsystem, &contents): Remove, since they are exported by...
7419 * lib/Autom4te/FileUtils.pm: this.
7420 More perldoc.
7421 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7422 * lib/Autom4te/FileUtils.pm: here.
7424 2003-08-20 Akim Demaille <akim@epita.fr>
7426 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7427 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
7428 from CVS Automake.
7430 2003-08-20 Akim Demaille <akim@epita.fr>
7432 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
7433 (autom4te-update): New.
7434 * Makefile.cfg (update): Bind autom4te-update.
7436 2003-08-19 Derek Price <derek@ximbiot.com>
7438 * lib/autotest/general.m4: Comment various HELP_* diversions.
7439 (PARSE_ARGS_BEGIN): New section for option parsing related
7440 initialization.
7441 (AT_ARG_OPTION,AT_ARG_OPTION_ARG,_AT_ARG_OPTION): New macros to define
7442 package specific options and associated help.
7444 2003-08-19 Akim Demaille <akim@epita.fr>
7446 * config/announce-gen, Makefile.cfg: New.
7447 * Makefile.am: Adjust.
7448 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
7450 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7452 * lib/autom4te.in (Automake-preselections): Preselect
7453 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
7454 and m4_sinclude.
7456 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7458 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
7459 (Autoconf-without-aclocal-m4): ... this new language.
7460 * doc/autoconf.texi (autom4te Invocation): Mention
7461 Autoconf-without-aclocal-m4.

7465 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
7466 RUN-IF-PASS optional arguments.

7475 STDOUT & STDERR arguments.
7477 2003-08-14 Derek Price <derek@ximbiot.com>
7479 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7480 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7481 shorter column three. Add DESCRIPTION to log file content.
7483 2003-08-13 Derek Price <derek@ximbiot.com>
7485 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7486 output.
7488 2003-08-12 Derek Price <derek@ximbiot.com>
7490 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7491 (AT_CHECK_NOESCAPE): Move core functionality to...
7492 (_AT_CHECK): ...this new macro.
7494 2003-08-07 Derek Price <derek@ximbiot.com>
7496 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7497 (AT_CHECK_NOESCAPE): ...to this new macro.
7499 2003-07-31 Paul Eggert <eggert@twinsun.com>
7501 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7502 in Bash 2.01. Problem reported by Brian Gough in
7503 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7505 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7507 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7508 -lcrt1.o, for OS X. (trivial change)
7510 2003-07-07 Paul Eggert <eggert@twinsun.com>
7512 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7513 inside '#ifndef __cplusplus'. Problem reported by
7514 Bob Friesenhahn.
7516 2003-07-06 Bill Clarke <llib@computer.org>
7518 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7519 'long', not 'int', for benefit of Sun's recent C++ compilers
7520 (trivial change). See:
7521 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7522 (This really should be 'intptr_t', not 'long', but that would
7523 take more work.)
7525 2003-06-25 Akim Demaille <akim@epita.fr>
7527 * lib/Makefile.am (autom4te.cfg): Make it read only.
7528 Depend on Makefile since it contains substitutions.
7529 From Paolo Bonzini.
7530 * lib/autom4te.in (args): Add local.at? for Autotest args.
7531 This change was made on autom4te.cfg which is generated.
7532 Reported by Raja R. Harinath.
7534 2003-06-25 Akim Demaille <akim@epita.fr>
7536 * doc/autoconf.texi (Header Portability): sys/mount.h.
7537 From Gareth McCaughan.
7539 2003-06-23 Akim Demaille <akim@epita.fr>
7541 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7542 not all of them. This fixes 1. the fact that when testing
7543 Autoconf there are many many config.log, 2. the incorrect use of
7544 top_srcdir to find config.log.
7545 Don't mix the detailed output of failed test with the summary of
7546 failures. Rather, append detailed log afterwards.
7548 2003-06-23 Akim Demaille <akim@epita.fr>
7550 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7551 always run: output config.log on $at_group_log.
7553 2003-06-23 Akim Demaille <akim@epita.fr>
7555 * tests/torture.at (#define header templates): Don't use quotes in
7556 C++ comments as it puzzles Emacs' sh font-lock-mode.
7558 2003-06-23 Akim Demaille <akim@epita.fr>
7560 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7561 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7562 * tests/atspecific.m4: Rename as...

7565 * tests/local.at: here.
7566 * tests/Makefile.am: Adjust.

7569 2003-06-21 Kevin Ryde <user42@zip.com.au>
7571 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7572 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7573 ensuring we add -std1 for full-ANSI.
7575 * doc/autoconf.texi (hdrindex): New macro.
7576 Add index entries for portability of various standard header files.
7578 2003-06-20 Akim Demaille <akim@epita.fr>
7580 * configure.ac: Bump to 2.57b.
7582 2003-06-20 Akim Demaille <akim@epita.fr>
7584 Version 2.57a.
7586 2003-06-20 Akim Demaille <akim@epita.fr>
7588 * bin/autom4te.in: Don't rely on $HOME being defined.
7589 Reported by Marc Espie as PR/233.
7591 2003-06-20 Akim Demaille <akim@epita.fr>
7593 * lib/autotest/general.m4: Use at_times_file only if used.
7594 From Nicolas Joly.

7598 * config/config.guess, config/config.sub, config/elisp-comp,
7599 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7600 Update from masters.
7602 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7604 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7605 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7606 (TEST_SCRIPT): New diversion.
7607 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7608 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7609 (AT_INIT): Support for expected failures.
7611 2003-06-02 Akim Demaille <akim@epita.fr>
7613 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7614 changes.
7615 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7616 Autoconf nor Automake.
7617 (&contents): New, from Automake.
7618 PODify.
7620 2003-05-28 Paul Eggert <eggert@twinsun.com>
7622 * NEWS, doc/autoconf.texi (Particular Functions),
7623 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7624 is the inverse of localtime.
7626 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7628 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7629 (handle_exec_errors): New function. Work around $! being
7630 altered by WEXITSTATUS.
7631 (xqx, xsystem): Use handle_exec_errors.
7633 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7635 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7636 Do not call `_exit()', simply modify `$?'.
7637 (xsystem): Reset $! before running system, and check it afterward.
7638 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7639 63 for version mismatches.
7641 2003-05-23 Akim Demaille <akim@epita.fr>
7643 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7644 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7645 the middle of a line).
7646 * lib/m4sugar/m4sugar.m4: Likewise.
7647 Remove useless spaces in comments.
7649 2003-05-23 Akim Demaille <akim@epita.fr>
7651 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7652 exit 63, so that we (or Automake's "missing") can tell the
7653 difference with a plain failure.
7654 * doc/autoconf.texi (Notices): Adjust.
7656 2003-05-23 Akim Demaille <akim@epita.fr>
7658 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7659 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7660 White spaces cleanup.
7662 2003-05-22 Jim Meyering <jim@meyering.net>
7663 Paul Eggert <eggert@twinsun.com>
7665 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7666 Remove `#include <stdlib.h>' from the list; we should never
7667 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7668 resulting namespace pollution would cause other tests to fail.
7669 Configure scripts run with some older versions of g++ and HP's
7670 aCC would fail due to such an #include. Problems reported by
7671 Matthew Mueller in <http://bugs.debian.org/120704> and by
7672 Keith Bostic in
7673 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7674 In the test, use the test declaration before including <stdlib.h>,
7675 as that's closer to how it'll be used.
7677 2003-05-23 Akim Demaille <akim@epita.fr>
7679 * doc/autoconf.texi (Header Portability): ucred.h.
7680 From Ian Redfern.
7682 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7684 Overhaul Autotest's logging: generate separate log files
7685 in testsuite.dir/NNN/testsuite.log, and append them to
7686 testsuite.log instead of re-running the test verbosely.
7688 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7689 file descriptor, write 0 to at_status_file instead of setting
7690 at_status=0, initialize some new variables (at_status_file,
7691 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7692 to rerun the tests, instead append the at_group_log to the
7693 at_suite_log when a test fails.
7694 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7695 with the AS_MESSAGE_LOG_FD redirected to stdout.
7696 (AT_CLEANUP): save the output status in $at_status_file
7697 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7698 its original place.
7699 (AT_CHECK): since tests are run with a redirected stdout,
7700 and used to be re-run in verbose mode, turn some $at_verbose
7701 into echo, and don't redirect the output of testing stdout
7702 and stderr.
7704 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7705 the name of the debugging directory and information about
7706 its contents.
7708 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7710 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7711 parameter.

7823 and truncate.
7825 2003-05-06 Akim Demaille <akim@epita.fr>
7827 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7828 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7829 by aclocal.m4 is changed it might require the importing of another
7830 m4 extension file, i.e., aclocal must be run.
7832 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7833 (&parse_args): Use --force with aclocal if required and supported.

7841 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7842 argument instead of a file name, so that the request file remains
7843 open during the whole autom4te run.
7844 ($icache_file): New.
7845 (&freeze): Lock the $icache_file.
7847 2003-04-29 Derek Price <derek@ximbiot.com>
7849 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7850 seperator with m4_append_uniq(). It doesn't work.
7851 (AT_CLEANUP): Add `;' to end of at_help_all.
7852 (AT_INIT): Allow --keywords to be specified more than once. When
7853 grepping $at_help_all for keywords, use the field and keyword

7855 to support the new --keywords behavior.
7857 2003-04-27 Karl Berry <karl@freefriends.org>
7859 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7860 align better with others. I also made some of the individual
7861 entries on one line, for brevity and to make it easier for me to
7862 sort my dir-example file in the Texinfo distribution :).

7929 header causes problems.
7931 2003-03-28 Akim Demaille <akim@epita.fr>
7933 * tests/torture.at (Configuring subdirectories): Require aclocal
7934 1.4, otherwise the test fails, as it does support configure.ac.

7939 * doc/autoconf.texi (C Compiler): `#line' portability.

7945 layout in order to allow scripting around test groups.

7972 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

8008 (Automake): Automake 1.5+ no longer requires special tools to be
8009 present on the developer's host.

8025 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
8026 to cope with DOS-style absolute paths, when constructing
8027 ${ac_make}.
8029 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
8030 When constructing paths with IFS=:, quote the path. If we're
8031 constructing a DOS-style absolute path, we don't want to split it
8032 on the colon.
8034 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
8035 in description.
8037 2003-02-25 Pavel Roskin <proski@gnu.org>

8045 2002-09-01 patch by replacing "test -n" with "test -z".
8046 This fixes a bug found by Jeff Painter and reported by Tom Epperly in

8049 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
8050 to fix a mismatch between example and discussion.
8052 2003-02-24 Kevin Ryde <user42@zip.com.au>
8054 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8055 format starting with "-".
8057 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8059 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8060 is not portable inside Makefile.
8062 2003-02-20 Akim Demaille <akim@epita.fr>
8064 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8065 compiler says yeah, but preproc says nope, compiler is right.
8066 Conversely, prompt the reader to send a bug report to the
8067 maintainers of the package, not of Autoconf.
8069 2003-02-20 Klee Dienes <kdienes@apple.com>
8071 * bin/autoreconf.in (autoreconf_current_directory): Properly
8072 handle an empty aclocal.m4.

8076 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
8077 $ac_prefix_program.
8078 From Larry Jones.
8080 2002-12-23 Paul Eggert <eggert@twinsun.com>
8082 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8083 innocuous variant befor including <limits.h> or <assert.h>. This
8084 works around a bug reported by Albert Chin: HP-UX 11i
8085 (and earlier versions) have a <limits.h> that declares
8086 gettimeofday and many other functions.
8088 2002-12-03 Paul Eggert <eggert@twinsun.com>
8090 Version 2.57.
8092 * NEWS, configure.ac: Update version.
8094 * doc/fdl.texi: Upgrade to FDL version 1.2.
8096 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8097 nontrivially in main's body, so that f's external declaration is
8098 not optimized away in AIX. This should fix the bug reported by
8099 Martin Frydl in
8100 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8102 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8103 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8104 defined, to support freestanding compilers. This should fix the
8105 bug reported by Momchil Velkov in
8106 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8108 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8109 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
8110 obsolete AC_CHECK_TYPE. The missing empty arg was reported
8111 by Simon Josefsson in

8114 * Makefile.maint (www-gnu): New macro.
8115 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
8116 the location has moved.
8118 2002-12-02 Martin Frydl <martin@systinet.com>
8120 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
8121 \(.*\) match is too long and there is something more to be checked.
8122 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
8124 2002-11-15 Akim Demaille <akim@epita.fr>

8129 From Paul Eggert.
8130 * config/move-if-change: Indenting changes.
8131 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
8132 * configure.ac (AM_INIT_AUTOMAKE): here.
8133 Require 1.7.1.
8135 2002-11-14 Akim Demaille <akim@epita.fr>
8137 Version 2.55.
8139 * config/config.guess, config/config.sub, config/install-sh:
8140 Update from masters.
8142 2002-11-14 Akim Demaille <akim@epita.fr>
8144 * Makefile.maint: Sync with Bison, i.e.:
8145 (po-check): Scan .l and .y files instead of the
8146 .c and the .h files that they generate. This fixes the bug
8147 reported by Tim Van Holder in:
8148 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8149 Look for N_ as well as for _. Try to avoid matching #define for
8150 N_ and _.
8151 From Paul Eggert.
8153 2002-11-14 Akim Demaille <akim@epita.fr>
8155 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8156 From Paul Eggert and Albert Chin-A-Young.
8158 2002-11-14 Akim Demaille <akim@epita.fr>
8160 * doc/autoconf.texi (C Compiler): Solitary backslashes.
8161 From Paul Eggert and Albert Chin-A-Young.
8163 2002-11-14 Kevin Ryde <user42@zip.com.au>
8165 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8166 than assigning in main, to avoid HP cc +O3 optimizing it away.
8168 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8170 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8171 option. Process --recheck after parsing all options. Pass -q
8172 option to configure on --recheck.
8173 (AC_OUTPUT): Pass -q from configure to config.status.
8174 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8175 arguments to record.
8176 * doc/autoconf.texi (config.status Invocation): Document
8177 config.status -q option.
8179 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
8181 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
8182 Makefile.in if Makefile.am exists.
8183 (output): Strip `.am' from Makefiles. Don't
8184 output AC_CONFIG_FILES if no Makefiles were found.
8186 2002-11-07 Akim Demaille <akim@epita.fr>
8188 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
8189 (local_updates): New.
8190 * Makefile.maint: Update, from CVS Bison.
8191 (local_updates): New.
8193 2002-11-06 Akim Demaille <akim@epita.fr>
8195 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
8196 declaration in extern "C" too.
8197 Reported by Roberto Bagnara.
8199 2002-11-06 Akim Demaille <akim@epita.fr>
8201 * tests/torture.at (Configuring subdirectories): Don't use grep
8202 -w.
8203 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
8204 Reported by Ezra Peisach.
8206 2002-11-05 Akim Demaille <akim@epita.fr>
8208 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8209 Remove.
8210 We _have_ to stop using the old compatibility scheme that tried to
8211 avoid useless backslashes because Libtool 1.4.3 contains a
8212 AC_DEFINE([error_t], [int],
8213 [Define to a type to use for \`error_t' if it is not
8214 otherwise available.])
8215 We _have_ to quote the single quote and backslashes with \. The
8216 old compatibility scheme saw that ` was backslashed, and therefore
8217 did not quote the single quote. Hence before this patch, Autoconf
8218 was not compatible with Libtool.
8220 2002-11-04 Paul Eggert <eggert@twinsun.com>
8222 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
8223 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
8224 LC_NAME, LC_PAPER, LC_TELEPHONE.
8225 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
8227 2002-11-04 Akim Demaille <akim@epita.fr>
8229 Version 2.54c.
8231 * Makefile.maint (update, cvs-update, po-update, do-po-update):
8232 New.
8233 * config/texinfo.tex: Update.
8235 2002-11-03 Akim Demaille <akim@epita.fr>
8237 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
8238 from...
8239 (&autoreconf): here.

8316 * tests/torture.at (Deep Package): New test.

8550 2002-10-22 Akim Demaille <akim@epita.fr>
8552 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

8556 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8557 strings.
8559 2002-10-22 Akim Demaille <akim@epita.fr>
8561 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

8608 longer required can still cause errors.
8609 Reported by Alexandre Duret-Lutz.
8611 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8612 to frozen files in @ARGV, as @ARGV must remain being a list of

8614 (&files_to_options): New function.
8615 (&freeze): Use &error.
8616 (&up_to_date): If a file that was included according to the cache
8617 is no longer there, then the output is out dated.

8619 --force is given.
8620 * tests/tools.at (autom4te cache): New.
8622 2002-10-16 Akim Demaille <akim@epita.fr>

8627 Factor some code.
8628 (&autoreconf): Report the directories we enter *and leave*, so
8629 that error messages can be easily located, and use GNU Make
8630 format, so that Emacs' compile mode understands us.
8631 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8632 if some file was changed instead of `print'.
8633 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

8667 file name to enable parallel executions.
8668 From Sam Varshavchik.
8670 2002-10-08 Akim Demaille <akim@epita.fr>
8672 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8673 aclocal invocation, as Gettext macros might not be visible to
8674 aclocal.
8675 Instead of blindly running autopoint, scan configure.ac (not the
8676 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8677 Reported by Paul D. Smith.
8679 2002-10-08 Paul Eggert <eggert@twinsun.com>
8681 Work around problems found when POSIXLY_CORRECT=1 is set.
8682 None of this seems to have anything to do with POSIX, really,
8683 but it's how Perl getopt works.
8684 * bin/autom4te.in (parse_args): Configure GetOpt with
8685 "permute", too.
8686 * doc/autoconf.texi (Invoking autom4te):
8687 --warning -> --warnings.

8709 * tests/torture.at (Configuring subdirectories): Be robust to
8710 users who use config.site to require for a cache: in this case,
8711 the two last configure runs, using two different sets of
8712 arguments, trigger a legitimate error.
8714 2002-09-28 Akim Demaille <akim@epita.fr>

8730 (tm_zone): Move their rules to...
8731 * lib/autoconf/types.m4: here, using AN_ macros.
8732 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8733 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)

8740 2002-09-28 Akim Demaille <akim@epita.fr>
8742 * lib/autoconf/autoscan.m4: New file.
8743 * lib/autoconf/autoconf.m4: Include it.

8745 that were listed in the original autoscan.list.
8746 * lib/autoconf/headers.m4: Similarly with headers.
8747 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8748 (.m4.m4f): Don't pass --prepend-include, since that's done by
8749 tests/autom4te itself.
8750 * lib/autoscan/Makefile.am: Include freeze.mk.
8751 (autoscan.list): New target --this file is no longer a source.
8752 (autoscan.pre): New file.
8754 2002-09-28 Akim Demaille <akim@epita.fr>
8756 * bin/autoscan.in (@kinds): Make them singular.
8757 Adjust all uses.
8758 (&init_tables): When --debug, report the list of rules to ease
8759 tracking changes in autoscan.list.
8760 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8762 2002-09-28 Akim Demaille <akim@epita.fr>
8764 * lib/autoscan/functions, lib/autoscan/headers,
8765 * lib/autoscan/identifiers, lib/autoscan/makevars,
8766 * lib/autoscan/programs: Merge into...
8767 * lib/autoscan/autoscan.list: this.
8768 * bin/autoscan.in (&init_tables): Adjust.
8770 2002-09-28 Akim Demaille <akim@epita.fr>
8772 * lib/autoscan/functions, lib/autoscan/headers,
8773 * lib/autoscan/identifiers, lib/autoscan/makevars,
8774 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8775 `functions' line is now prefixed with `function:'.
8776 * bin/autoscan.in (&init_tables): Adjust.
8778 2002-09-28 Akim Demaille <akim@epita.fr>
8780 From now on, autoscan files must always map a macro name to a
8781 word: there is no `default' macro for autoscan.
8783 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8784 all.
8785 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8786 explicit.
8788 2002-09-28 Akim Demaille <akim@epita.fr>
8790 * bin/autoscan.in (%c_keywords): Remove.
8791 (&used): Keep only track of the words we might be interested in.
8792 (&output_kind): It is no longer needed to look for non active
8793 checks.
8795 2002-09-27 Akim Demaille <akim@epita.fr>
8797 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

8802 2002-09-27 Akim Demaille <akim@epita.fr>
8804 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8805 from /tmp.
8806 Thanks to Bill Moseley and Paul Eggert.
8807 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8808 the tmpdir must be created.
8809 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8810 dir be in the build tree, instead of $TMPDIR.
8812 2002-09-27 Akim Demaille <akim@epita.fr>
8814 * bin/autoscan.in: Improve the comments.
8815 (&parse_args): Drop obsolete undocumented options.
8816 (&output_kind): Output warnings.
8817 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

8823 Reported by Ralf Corsepius.
8824 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8826 2002-09-26 Akim Demaille <akim@epita.fr>
8828 Single suffix rules and seperated dependencies are not portable.
8830 * doc/autoconf.texi (Installation Directory Variables): Update.
8831 (Limitations of Make): Some about `Single Suffix Rules and
8832 Separated Dependencies'.
8833 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8834 (ifnames, autoscan, autom4te): Un-factor into several rules.
8836 2002-09-25 Paul Eggert <eggert@twinsun.com>
8838 * BUGS (Interoperability bugs): New section. Mention libtool
8839 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8841 2002-09-24 Paul Eggert <eggert@twinsun.com>
8843 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8844 make handles suffix-rules differently from GNU make.
8846 * bin/Makefile.am (SUFFIXES, .in): Remove.
8847 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8848 Move the body of the old .in rule here.
8850 2002-09-16 Akim Demaille <akim@epita.fr>
8852 i960 compilers create `b.out' files by default.
8853 Reported by Ralf Corsepius.
8855 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8856 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8858 2002-09-13 Paul Eggert <eggert@twinsun.com>
8860 * doc/autoconf.texi (Particular Headers): Remove obsolete
8861 reference to `struct timezone' in the description of
8862 AC_HEADER_TIME.
8864 2002-09-13 Akim Demaille <akim@epita.fr>
8866 Version 2.54.
8868 * config/config.sub, config/config.guess: Update.
8869 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8870 * Makefile.am: Adjust.
8872 2002-09-13 Akim Demaille <akim@epita.fr>
8874 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8875 reading config.log when the compiler is rejected.
8876 Suggested by Guido Draheim.
8878 2002-09-13 Akim Demaille <akim@epita.fr>
8880 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8881 (chdir_init) might hang when stat'ing mounted directories.
8882 Reported by Vance Shipley.
8884 2002-09-12 Akim Demaille <akim@epita.fr>
8886 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8887 the lists.
8889 2002-09-12 Akim Demaille <akim@epita.fr>
8891 * doc/autoconf.texi (Defining Symbols): Present two different
8892 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8893 difference between 1 argument calls, and 2-3 argument calls.
8895 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8897 * doc/autoconf.texi: Review grammar and punctuation.
8899 2002-09-11 Paul Eggert <eggert@twinsun.com>
8901 * doc/autoconf.texi: Fix minor formatting, spelling, and
8902 grammatical typos.
8903 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8904 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8905 is obsolescent.
8907 2002-09-11 Akim Demaille <akim@epita.fr>
8909 * doc/autoconf.texi (Questions): Rename as...
8910 (FAQ): this.
8911 (Defining Directories): New.
8913 2002-09-09 Akim Demaille <akim@epita.fr>
8915 * doc/autoconf.texi (Making testsuite Scripts): Update.
8916 Suggested by Nishio Futoshi.
8918 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8920 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8921 plain `@' is wanted.
8923 2002-09-09 Akim Demaille <akim@epita.fr>
8925 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8926 `duplicates', since the algorithm was too naive and could keep
8927 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8928 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8929 Reported by Ralf Corsepius.
8930 * tests/torture.at (Configuring subdirectories): Exercise these
8931 cases.
8933 2002-09-09 Akim Demaille <akim@epita.fr>
8935 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8936 looking for a replacement file.
8937 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8938 directory is relative.
8939 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8940 directory definition.
8941 Reported by Andreas Schwab and Jim Meyering.
8943 2002-09-06 Akim Demaille <akim@epita.fr>
8945 * doc/autoconf.texi (Setting Output Variables): Clarify what
8946 precious variables are.
8947 Suggested by Pontus Skoeld.
8949 2002-09-05 Akim Demaille <akim@epita.fr>
8951 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8952 (ifnames, autoscan, autom4te): Since we don't only depend on
8953 configure.ac variables (such as VERSION etc.), but also on prefix
8954 and so forth, depend on Makefile, not configure.ac.
8955 Reported by Alexandre Duret-Lutz.
8956 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8958 2002-09-05 Kevin Ryde <user42@zip.com.au>
8960 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8961 doesn't seem to be confined to ia64, just say "some versions".
8963 2002-09-04 Akim Demaille <akim@epita.fr>
8965 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8966 Automake 1.6c.
8967 * Makefile.am (maintainer-clean-local): Remove.
8968 (MAINTAINERCLEANFILES): Remove COPYING.
8970 2002-09-03 Paul Eggert <eggert@twinsun.com>
8972 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8973 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8974 Brinkmann.
8976 2002-09-03 Akim Demaille <akim@epita.fr>
8978 * configure.ac: Bump to 2.53d.
8979 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8980 as of today, on Automake's team suggestion.
8982 2002-09-03 Akim Demaille <akim@epita.fr>
8984 Version 2.53c.
8986 2002-09-02 Akim Demaille <akim@epita.fr>
8988 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8989 SITE_MACRO_DIR.
8990 * configure.ac: Disable SITE_MACRO_DIR.
8992 2002-09-02 Jim Meyering <meyering@lucent.com>
8994 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8995 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8996 Also, tweak grammar: s/make sure to/be sure to/.
8998 2002-09-02 Paul Eggert <eggert@twinsun.com>
9000 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9001 directory names are generally preferable to physical names.
9003 2002-09-02 Akim Demaille <akim@epita.fr>
9005 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9006 Reported by Raja R. Harinath.
9007 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9008 * bin/autoupdate.in: Use error instead of die.
9010 2002-09-01 Paul Eggert <eggert@twinsun.com>
9012 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9013 ordinary shell concatenation rather than echo+tr+sed command that
9014 runs afoul of a long-line-related sed bug in Solaris 8.
9016 * bin/autoheader.in (parse_args): --warning -> --warnings.
9018 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9019 stdout, as traditional "ls" does.
9020 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9021 _AC_COMPILER_EXEEXT_O): Likewise.
9022 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9024 * bin/autoconf.as: Add --prepend-include option. This patch was
9025 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9026 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9028 * bin/autoconf.in, configure: Regenerate.
9030 * doc/autoconf.texi (Special Shell Variables): Mention
9031 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9033 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9034 MAILPATH and set PS1, PS2, PS4 to default values, to work
9035 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9036 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9037 the Autoconf documentation specifies; fall back to "unset" only if
9038 this fails. Use a shell for-loop for this rather than an m4 loop,
9039 to shorten the output script.
9041 2002-08-30 Paul Eggert <eggert@twinsun.com>
9043 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9044 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9045 for the CDPATH problem. Document PWD.
9046 (Limitations of Builtins): Document the problem that "cd $foo" and
9047 "ls $foo" may refer to different directories in shells conforming
9048 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9049 example, since the old example is now out of date.
9051 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9052 FOO" and "ls FOO" talk about different directories; this catches
9053 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9054 spaghetti.
9056 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9057 of rolling our own unset.
9058 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9059 in practice we needn't worry about CDPATH if unset doesn't work.
9061 * Makefile.in, aclocal.m4, bin/Makefile.in,
9062 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9063 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9064 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9065 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9066 tests/Makefile.in: Regenerate with Automake 1.6.3.
9068 * config/config.guess, config/config.sub, config/mkinstalldirs:
9069 Update.
9071 * configure: Regenerate with self.
9073 2002-08-30 Kevin Ryde <user42@zip.com.au>
9075 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9076 default output.
9078 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9080 * bin/autom4te.in (Request::load): Correctly test for "do" read
9081 failure.
9083 2002-08-29 Akim Demaille <akim@epita.fr>
9085 * lib/Autom4te/General.pm (&xqx): New.
9086 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9087 hand, which is not portable.
9088 (&error): New.
9089 * bin/autom4te.in: Use them.
9090 Use &error instead of die.
9091 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9092 Adjust.
9094 2002-08-17 Paul Eggert <eggert@twinsun.com>
9096 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9097 default list of compilers to try, since it was long ago superseded
9098 by the ksh fc builtin. Suggested by Steven G. Johnson.
9100 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9102 * doc/autoconf.texi (Invoking autom4te): End the option table,
9103 fixing a bug introduced by the previous patch.
9104 (Limitations of Make): Add a 'target lookup' subentry in the
9105 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9107 2002-07-29 Mark D. Roth <roth@feep.net>
9109 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9110 options and use $AUTOM4TE_PATH.
9111 * doc/autoconf.texi: Remove documentation of autom4te
9112 --include-envvar and --site-macro-subdir options and document
9113 use of $AUTOM4TE_PATH.
9114 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9115 arguments from each language section.
9117 2002-07-29 Paul Eggert <eggert@twinsun.com>
9119 * doc/install.texi: Include copyright symbol in copyright notice.
9121 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9122 Replace with:
9123 (AM_MAKEINFOFLAGS): New macro.
9124 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9125 * Makefile.am (INSTALL): Use the new macros.
9126 Use -o rather than --output, since "missing" does not grok --output.
9128 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9130 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9131 comments do not always work. Never trust the exit status of
9132 `make -k'.
9134 2002-07-24 Kevin Ryde <user42@zip.com.au>
9136 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9137 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9139 2002-07-23 Paul Eggert <eggert@twinsun.com>
9141 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9142 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9143 apparently treats PATH="nonexistent" as if it contained ".".
9144 Bug reported by Stefan `Sec' Zehl.
9146 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9148 * doc/autoconf.texi (Limitations of Make): Mention the special
9149 handling of the obj/ directory by BSD make.
9151 2002-07-20 Kevin Ryde <user42@zip.com.au>
9153 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
9154 backslashes.
9156 2002-07-19 Akim Demaille <akim@epita.fr>
9158 * doc/autoconf.texi (Function Portability): `exit'.
9159 (Programming in M4sh): Ethymology of M4sh.
9161 2002-07-19 Akim Demaille <akim@epita.fr>
9163 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
9165 2002-07-18 Akim Demaille <akim@epita.fr>
9167 Version 2.53b.
9169 2002-07-18 Akim Demaille <akim@epita.fr>
9171 * config/config.guess, config/config.sub: Update.
9173 2002-07-18 Akim Demaille <akim@epita.fr>
9175 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
9176 Automake's parts.
9178 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
9179 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
9180 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
9182 2002-07-18 Akim Demaille <akim@epita.fr>,
9183 Alexandre Duret-Lutz <duret_g@epita.fr>
9185 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
9186 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
9188 2002-07-17 Russ Allbery <rra@stanford.edu>
9190 * doc/autoconf.texi (Initializing configure): Clarify the
9191 description of the tarname default.
9193 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
9195 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
9196 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
9197 latter was not run.
9199 2002-07-17 Akim Demaille <akim@epita.fr>
9201 * lib/Autom4te/General.pm (find_file): Browse the directories in
9202 the order they are given.
9204 2002-07-17 Akim Demaille <akim@epita.fr>
9206 * tests/wrapsh.as, tests/wrappl.as: Merge into...
9207 * tests/wrapper.as: this.
9208 * tests/Makefile.am, configure.ac: Adjust.
9210 2002-07-17 Mark D. Roth <roth@feep.net>
9212 * configure.ac: Add --enable-site-macro-dir option.
9213 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
9214 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
9215 --site-macro-subdir options.
9216 * bin/autoconf.in: Add --prepend-include option.
9217 * bin/autoheader.in: Add --prepend-include option.
9218 * bin/autoreconf.in: Add --prepend-include option.
9219 * bin/autoscan.in: Add --prepend-include option.
9220 * bin/autoupdate.in: Add --prepend-include option.
9221 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
9222 macro directory, remove note that include path directories are

9270 2002-06-27 Paul Eggert <eggert@twinsun.com>
9272 * config/install-sh: Quote $src. Prefer || to test's -o option,
9273 as per "Limitations of Builtins".
9274 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
9275 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.

9299 on Solaris 2.5.1.
9301 2002-06-11 Andreas Schwab <schwab@suse.de>

9305 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9307 * bin/autom4te.in ($cache): Don't define using `$me', the name
9308 of the cache should not depend on the name under which autom4te
9309 was installed.
9311 2002-06-07 Akim Demaille <akim@epita.fr>
9313 * tests/tools.at (autoconf: forbidden tokens, basic)

9315 words in autom4te.in.
9317 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
9319 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
9320 _AC_LANG_PROGRAM_C_F77_HOOKS.
9322 2002-06-07 Akim Demaille <akim@epita.fr>
9324 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
9325 rename as...
9326 (AC_REPLACE_FNMATCH): this.
9327 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
9328 AC_FUNC_FNMATCH_GNU.
9330 2002-06-07 Akim Demaille <akim@epita.fr>
9332 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
9333 Rosetta Stone for Unix.
9335 2002-06-07 Akim Demaille <akim@epita.fr>
9337 * bin/autom4te.in (warn_forbidden): When rejecting a token,
9338 suggest m4_pattern_allow.
9339 Suggested by Adam J. Richter.
9341 2002-06-07 Akim Demaille <akim@epita.fr>
9343 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

9346 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

9348 Use ac_config_libobj_dir to find the replacement files.
9349 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...

9359 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
9360 if ln doesn't work.
9361 * NEWS: Likewise.
9362 * doc/autoconf.texi (Configuration Links): Likewise.

9400 version of Autoconf that is discussed.
9402 2002-05-22 Paul Eggert <eggert@twinsun.com>
9404 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
9405 from the default list of compilers to try. Suggested by
9406 Kate Hedstrom.
9407 * NEWS: Document the above.
9408 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
9410 2002-05-17 Paul Eggert <eggert@twinsun.com>
9412 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9413 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9414 This improves on an earlier suggestion by H. Peter Anvin.
9416 2002-05-16 Paul Eggert <eggert@twinsun.com>
9418 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9419 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9420 Both macros now accept an optional source-dir arg.
9421 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9423 * NEWS: Document this.
9424 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9426 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9427 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9428 not for GNU extensions; this undoes part of the 2000-11-03 change,
9429 reverting to 2.13-compatible behavior.
9430 Add new optional argument DIR.
9431 (AC_FUNC_FNMATCH_GNU): New macro.
9433 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9435 2002-05-08 Paul Eggert <eggert@twinsun.com>
9437 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9438 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9439 and it causes a 'test' syntax error if it fails.
9440 Bug reported by Stephen Gildea.
9442 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9443 If prototypes are supported, use them to check this at compile-time,
9444 instead of trying to check it at run-time. If we must do a run-time
9445 check, assume that setvbuf is standard when cross-compiling, as
9446 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9447 Bug reported by Paul D. Smith.
9449 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9450 argument specifying location of getloadavg.c. This removes a
9451 FIXME. This idea was taken from Jim Meyering's implementation in
9452 textutils.
9453 * doc/autoconf.texi (Particular Functions): Document this.
9454 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9455 that's what the code does; this fixes a bug reported by
9456 Paul D. Smith.
9458 2002-05-03 Akim Demaille <akim@epita.fr>
9460 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9461 autopoint instead of gettextize.
9462 ($uses_alocal): Rename as...
9463 ($uses_aclocal): this.
9464 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9465 Suggested by Bruno Haible.
9467 2002-05-03 Akim Demaille <akim@epita.fr>
9469 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9471 2002-04-29 Paul Eggert <eggert@twinsun.com>
9473 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9474 files to be 1 second older; just set them to be the same time.
9475 Also, sleep 1 second after the first aclocal, to work around
9476 problems with sub-second time stamps on the input files.
9478 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9480 * doc/autoconf.texi: Mention "set -e -x" lossage
9481 under node "Limitations of Builtins".
9483 2002-04-29 Akim Demaille <akim@epita.fr>
9485 * doc/install.texi: Better wording for setting variables when
9486 running configure.
9487 From Christian Cornelssen.
9489 2002-04-29 Akim Demaille <akim@epita.fr>
9491 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9492 of lack of $LINENO support, then the test will compare the $LINENO
9493 in testsuite vs. the lineno in the test file. This is wrong, of
9494 course.
9495 Be sure to protect it.
9496 Reported by Patrick Welche.
9498 2002-04-25 Akim Demaille <akim@epita.fr>
9500 * doc/autoconf.texi (Obsolete Macros): Typo.
9501 Reported by Vladimir Volovich.
9503 2002-04-25 Akim Demaille <akim@epita.fr>
9505 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9506 than some of the input files, hence, on the second run of aclocal,
9507 if some of its input are younger, make them older.
9508 Suggested by Paul Eggert.
9510 2002-04-25 Akim Demaille <akim@epita.fr>
9512 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9513 Thanks to Paul Eggert.
9515 2002-04-25 Akim Demaille <akim@epita.fr>
9517 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9518 and ac_subst_vars be sh variables containing the list of
9519 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9520 DEFAULT diversion.
9521 (_AC_INIT_PREPARE): Use them to log them.
9522 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9523 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9524 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9525 _AC_SUBST_FILES and _AC_SUBST_VARS.
9526 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9528 2002-04-24 Akim Demaille <akim@epita.fr>
9530 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9531 autoheader, so that automake does not complain about a missing
9532 config.h.in that was to be created.
9534 2002-04-23 Akim Demaille <akim@epita.fr>
9536 * bin/autoheader.in (parse_args): --warning takes an argument.
9537 Fixes PR/220.
9539 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9541 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

9556 Reported by Gregory Giannoni.
9558 2002-04-22 Akim Demaille <akim@epita.fr>
9560 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
9561 Fixes false failures on Darwin.

9586 Minor spelling and grammar fixes.
9588 * doc/autoconf.texi: Follow the outline suggested in the GNU
9589 Sample Texts sections of the Texinfo 4.2 manual. Most
9590 importantly, this makes sure that the copyright notices appear in
9591 all output formats. You probably need Texinfo 4.2 to generate
9592 the manual now.
9594 Fix some bugs when using "$@" when there might be zero positional

9618 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9620 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

9647 * lib/autotest/general.m4 (AT_INIT): Likewise.
9648 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9649 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9650 AS_SHELL_SANITIZE.
9652 Use this M4sh to generate Autoconf's shell scripts.
9654 * tests/wrapsh.as: New, precursor of wrapsh.in.

9697 Don't use the KILL diversion, as it kills spurious output, which
9698 results in failures being hidden.

9709 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9710 expanded if $# <= 2.
9712 * bin/autoreconf.in (autoreconf): Run automake after rerunning
9713 aclocal.
9715 2002-04-03 Akim Demaille <akim@epita.fr>
9717 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
9718 (_AC_COMPILER_EXEEXT_REJECT): New.
9719 Also recognize *.bb and *.bbg as compilation byproducts.
9720 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9721 (_AC_COMPILER_OBJEXT): Use them.
9722 Fixes Debian #138666.
9724 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9726 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9728 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9729 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9730 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9731 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9732 (AC_C_CONST): Same.
9733 (AC_C_INLINE): Same.
9734 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
9735 * doc/autoconf.texi, NEWS: Document.
9736 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9737 AC_C_CROSS.
9739 2002-04-02 Akim Demaille <akim@epita.fr>
9741 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
9742 _AS_MKDIR_P_PREPARE.
9744 2002-03-28 Kevin Ryde <user42@zip.com.au>
9746 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9747 to avoid versions of HP C which don't allow that.
9749 2002-03-27 Paul Eggert <eggert@twinsun.com>
9751 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9752 (AS_SHELL_SANITIZE): Invoke it.
9753 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9755 2002-03-26 Akim Demaille <akim@epita.fr>
9757 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9759 2002-03-26 Akim Demaille <akim@epita.fr>
9761 * doc/autoconf.texi (Introduction): The GNATS base moved.
9763 2002-03-25 Paul Eggert <eggert@twinsun.com>
9765 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9766 as POSIX requires, as it doesn't work with Zsh.
9767 * doc/autoconf.texi (Assignments): Document the problem.
9769 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9771 * doc/autoconf.texi (Limitations of Make): Mention more issue
9772 about VPATH, overriding of macros in sub-makes, and handling of
9773 SHELL.
9775 2002-03-21 Paul Eggert <eggert@twinsun.com>
9777 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9778 problem with here-document buffer boundaries.
9780 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9781 when reinvoking the shell, to work around problems with installers
9782 who put strange things like "cd" commands in their environments.
9784 2002-03-19 Akim Demaille <akim@epita.fr>
9786 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9787 From Aaron Ucko.
9789 2002-03-19 Akim Demaille <akim@epita.fr>
9791 * bin/autoscan.in (scan_file): Specify the location in `&used'
9792 invocations.
9793 From Nicolas Joly.
9795 2002-03-19 Akim Demaille <akim@epita.fr>
9797 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9798 From Nishio Futoshi.
9800 2002-03-19 Akim Demaille <akim@epita.fr>
9802 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9804 2002-03-18 Paul Eggert <eggert@twinsun.com>
9806 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9807 (Limitations of Usual Tools): Add mkdir section.
9809 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9810 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9811 back on AS_DIRNAME to compute prefixes otherwise; this is
9812 roughly what mkinstalldirs does. That way, we need not have
9813 our own filename disassembler. The old disassembler did not
9814 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9816 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9817 Create at_test_all by a series of assignments,
9818 not by a single assignment of a long string. The latter causes ksh
9819 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9820 presumably because of a buffer overrun.
9822 2002-03-14 Paul Eggert <eggert@twinsun.com>
9824 * lib/autotest/general.m4 (at_times_skip):
9825 Renamed from at_times. Now a boolean.
9826 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9827 says 'times: not found'.
9829 2002-03-14 Akim Demaille <akim@epita.fr>
9831 * bin/autoreconf.in (&study_gettextize): New.
9832 (&autoreconf): Handle newest gettextize.
9833 Rerun aclocal if needed.
9834 Suggested by Andreas Schwab.
9836 2002-03-13 Akim Demaille <akim@epita.fr>
9838 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9840 2002-03-13 Akim Demaille <akim@epita.fr>
9842 * doc/autoconf.texi (Header Portability): New.
9843 Add information about stdint.h and inttypes.h from Paul Eggert.
9845 2002-03-13 Akim Demaille <akim@epita.fr>
9847 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9848 -p'.
9849 From Bob Proulx.
9851 2002-03-12 Akim Demaille <akim@epita.fr>
9853 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9854 m4_require.
9856 2002-03-11 Andreas Schwab <schwab@suse.de>
9858 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9859 does not do it if --with-lispdir is given.
9861 2002-03-08 Akim Demaille <akim@epita.fr>
9863 Version 2.53.
9865 2002-03-08 Akim Demaille <akim@epita.fr>
9867 * doc/autoconf.texi (Subdirectories): Clarify that the
9868 subdirectory should exist.
9870 2002-03-08 Akim Demaille <akim@epita.fr>
9872 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9874 2002-03-08 Akim Demaille <akim@epita.fr>
9876 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9877 aliases the actual variables, and modifications of the former
9878 affect the latter.
9880 2002-03-08 Akim Demaille <akim@epita.fr>
9882 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9883 because of C-c: have m4 output in tmp files, then mv them.
9885 2002-03-08 Akim Demaille <akim@epita.fr>
9887 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9888 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9889 * bin/ifnames.in: Copyright update.
9891 2002-03-08 Akim Demaille <akim@epita.fr>
9893 * doc/autoconf.texi (Invoking autom4te): New.
9895 2002-03-05 Akim Demaille <akim@epita.fr>
9897 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9898 Kevin Ryde.
9900 2002-03-05 Akim Demaille <akim@epita.fr>
9902 Version 2.52i.
9904 2002-03-04 Akim Demaille <akim@epita.fr>
9906 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9907 * lib/autoconf/general.m4 (AC_INIT): More informative error
9908 message for LIBOBJ.
9910 2002-03-04 Akim Demaille <akim@epita.fr>
9912 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9913 parallel builds.
9915 2002-03-04 Akim Demaille <akim@epita.fr>
9917 * doc/autoconf.texi (Transforming Names): Equality between target
9918 and host is irrelevant.
9919 (Specifying Names, Canonicalizing): Remove all references to the
9920 backward compatibility hooks. Rather, collect them all into...
9921 (Hosts and Cross-Compilation): this new section.
9922 * doc/install.texi (System Type): Ditto.
9923 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9924 that `--host' implies cross-compilation.
9926 2002-03-04 Akim Demaille <akim@epita.fr>
9928 * doc/autoconf.texi (Evaluation Macros): New.
9929 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9930 useless.
9931 (_m4_foreach): Define the variant with immediate evaluation so
9932 that it contains exactly the items, not an expression which
9933 evaluation is the current item.
9934 (m4_re_string, m4_re_word): Don't over quote them.
9936 2002-03-04 Akim Demaille <akim@epita.fr>
9938 Instead of having stacking `shift's evaluated at the end, let
9939 `foreach' loops immediately evaluate them.
9941 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9942 $*. This is the n-th time I change my mind, but hopefully this is
9943 the last...
9944 (m4_lquote): New.
9945 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9946 efficient.
9947 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9948 it was only a hack for m4_text_wrap.
9949 (m4_car2): Remove, replaced by...
9950 (m4_cdr): New.
9951 (_m4_foreach): Adjust.
9952 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9953 m4_bpatsubst for clarification.
9955 2002-03-04 Akim Demaille <akim@epita.fr>
9957 * doc/autoconf.texi (Changequote is Evil): New.
9959 2002-03-03 Kevin Ryde <user42@zip.com.au>
9961 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
9962 on old systems like SunOS.
9964 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
9966 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,

9984 From Akinori Musha.
9986 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9988 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9989 translate \r\n to \n.
9991 2002-02-07 Akim Demaille <akim@epita.fr>
9993 Version 2.52h.
9995 2002-02-07 Akim Demaille <akim@epita.fr>
9997 Fix Autoconf PR/209.
9998 Also reported by Frank Denis.
10000 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
10002 2002-02-07 Akim Demaille <akim@epita.fr>
10004 Fix Autoconf PR/207:
10005 AC_PREFIX_PROGRAM fails with dashed program names
10007 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
10008 variable when looking for the prefix program.
10009 Now it also works for shell variables.
10011 2002-02-07 Akim Demaille <akim@epita.fr>
10013 * doc/autoconf.texi (Limitations of Builtins): More about
10014 case/esac.

10018 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
10019 case/esac, some shells don't support it.
10020 Reported by Zack Weinberg.
10021 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
10023 2002-02-06 Akim Demaille <akim@epita.fr>
10025 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
10026 sure not to introduce newlines in at_groups.
10027 * lib/autotest/Makefile.am (autotest.m4f): Typo.
10029 2002-02-06 Akim Demaille <akim@epita.fr>
10031 * tests/torture.at (Configuring subdirectories): Skip if aclocal
10032 is not available.
10034 2002-02-05 Paul Eggert <eggert@twinsun.com>
10036 * doc/autoconf.texi (Specific Compiler Characteristics):
10037 Describe HP-UX cc bug workaround more accurately.
10038 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
10039 not unsigned long.
10040 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
10041 cross-compilers, too. This undoes some of the most recent change
10042 to this file.
10044 2002-02-05 Akim Demaille <akim@epita.fr>
10046 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
10047 to make sure they are up to date when `check' is run.
10049 2002-02-05 Akim Demaille <akim@epita.fr>
10051 * doc/autoconf.texi (Making testsuite Scripts): Document

10056 * lib/freeze.mk: New.
10058 2002-02-05 Akim Demaille <akim@epita.fr>
10060 Implement `autom4te --freeze'.
10062 * bin/autom4te.in (&freeze): New.
10063 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
10064 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
10066 2002-02-05 Akim Demaille <akim@epita.fr>
10068 * bin/autom4te.in (&parse_args): Implement `frozen files are
10069 optional are the sum of the previous files on the command line'.
10070 Also, pass `--reload-state=' on them, so...
10071 (handle_m4): don't.
10072 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10073 (M4sh): Rely on M4sugar.
10074 (Autotest, M4sh, M4sugar): Use frozen files.
10076 2002-01-31 Akim Demaille <akim@epita.fr>
10078 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
10079 * doc/autoconf.texi (Initializing configure): Adjust.
10081 2002-01-30 Akim Demaille <akim@epita.fr>
10083 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
10084 alphanumeric to `-' instead of `_'.
10086 2002-01-30 Akim Demaille <akim@epita.fr>
10088 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10089 for plain code, the other for cross-compilation code. The latter
10090 is now run with GCC only.
10091 * doc/autoconf.texi (Compilers and Preprocessors): New.
10093 2002-01-30 Akim Demaille <akim@epita.fr>
10095 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
10096 values.
10097 * doc/autoconf.texi (Initializing configure): Explain how to
10098 change AC_INIT default values.
10100 2002-01-29 Akim Demaille <akim@epita.fr>
10102 * tests/torture.at (Configuring subdirectories): Use configure.in,
10103 so that aclocal 1.4 works.
10104 Reported by Alexandre Duret-Lutz and Larry Schmitt.
10106 2002-01-28 Akim Demaille <akim@epita.fr>
10108 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10109 needs an argument.
10111 2002-01-28 Akim Demaille <akim@epita.fr>
10113 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10114 AUTOTEST_PATH *after* it was set.
10115 Don't put `.' in the PATH: the user should be precise and `./' if
10116 needed. In addition, given that the test suite does some `cd', if
10117 `.' is in the path, the `tested programs' sections will report
10118 programs found in the test suite's directory, while during the
10119 tests (performed in their own directory), these programs are no
10120 longer visible. In other words, the results is confusing and
10121 useless.
10122 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10124 2002-01-24 Akim Demaille <akim@epita.fr>
10126 Version 2.52g.

10133 2002-01-24 Akim Demaille <akim@epita.fr>
10135 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
10136 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
10137 Bourne. Use /bin/sh.
10138 From Andreas Buening.
10140 2002-01-24 Akim Demaille <akim@epita.fr>
10142 * config/config.guess, config/config.sub, config/texinfo.tex:

10150 * config/missing.m4, config/sanity.m4, config/select.m4,
10151 * config/strip.m4: Remove, to ease sync'ing with any version of
10152 Automake.
10154 2002-01-24 Akim Demaille <akim@epita.fr>
10156 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
10157 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
10158 Reported by Geir Ove Myhr.
10160 2002-01-21 Akim Demaille <akim@epita.fr>
10162 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
10164 2002-01-21 Akim Demaille <akim@epita.fr>
10166 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10167 message on invalid options.
10168 * bin/autom4te.in (parse_args): Don't use
10169 Autoconf::General::getopt with non valid options.
10171 2002-01-17 Jim Meyering <meyering@lucent.com>
10173 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10174 $ac_cv_exeext so we don't use an old, invalid, cached value.
10176 2002-01-11 Akim Demaille <akim@epita.fr>
10178 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
10179 Meyering.

10181 limitation.

10183 * lib/autoscan/functions: Adjust.
10185 2002-01-06 Akim Demaille <akim@epita.fr>
10187 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10188 package.m4, since is really depends upon configure.ac, not
10189 configure.
10190 * doc/autoconf.texi (testsuite Scripts): Adjust.
10191 * tests/Makefile.am (package.m4): New.
10192 EXTRA_DIST it since its a source.
10194 2002-01-06 Akim Demaille <akim@epita.fr>
10196 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10197 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10198 and PACKAGE_BUGREPORT from here...
10199 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10200 arguments.
10201 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10202 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10203 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
10204 * tests/tools.at (autoheader): Adjust.
10205 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
10207 2002-01-06 Akim Demaille <akim@epita.fr>
10209 * bin/autoscan.in (scan_file): Use `&used'.
10211 2002-01-03 Akim Demaille <akim@epita.fr>
10213 * doc/autoconf.texi (Output): Improved wording regarding use of
10214 AC_OUTPUT.
10215 From Olly Betts.
10217 2001-12-18 Kevin Ryde <user42@zip.com.au>
10219 * doc/autoconf.texi (Function Portability): Add notes on sscanf
10220 sometimes needing writable input.
10222 2001-12-17 Jim Meyering <meyering@lucent.com>
10224 * doc/autoconf.texi (New Macros): Tweak wording.
10226 2001-12-14 Akim Demaille <akim@epita.fr>
10228 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10229 trailing files, don't apply `-rf' to files which might not be
10230 created by configure (core, core.*, and *.core), but just `rm -f'.
10231 Suggested by Jonathan Kamens.
10233 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10235 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
10237 2001-12-14 Akim Demaille <akim@epita.fr>
10239 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
10241 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
10243 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
10244 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
10245 abs_srcdir, top_srcpath to abs_top_srcdir.
10246 (_AC_OUTPUT_FILES): Adjust.
10247 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
10248 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
10249 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10251 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
10253 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
10254 C/Fortran linking on HP/UX, by extracting the Fortran library
10255 search path from the LPATH line in the $F77 -v output.
10257 2001-12-12 Kevin Ryde <user42@zip.com.au>
10259 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10260 forbidden file descriptors table.
10262 2001-11-26 Akim Demaille <akim@epita.fr>
10264 * bin/autoscan.in (%c_keywords): Build it at top level.
10265 Map to 1 in order to simplify its uses.
10267 2001-11-26 Akim Demaille <akim@epita.fr>
10269 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10270 Remove $filepath, useless.
10271 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10272 variables, they are really part of the tokens.
10273 Split the input line on spaces and then look for tokens.
10274 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10275 because of `lex$U.$(OBJEXT)'.
10276 (&scan_files): Use "@list" instead of join.
10277 * doc/Makefile.am (CLEANFILES): Add *.fns.
10279 2001-11-26 Akim Demaille <akim@epita.fr>
10281 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10282 Remove, replaced by...
10283 * tests/wrappl.in: Be common for all the Perl executables.
10284 In particular autoscan and autoheader want -I.
10285 * configure.ac: Adjust.
10286 * lib/autoscan/headers: errno.h is portable.
10288 2001-11-26 Akim Demaille <akim@epita.fr>
10290 * bin/autoscan.in (used): New.
10291 Use it.
10293 2001-11-26 Akim Demaille <akim@epita.fr>
10295 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10296 directives.
10297 (&scan_sh_file): Remove a duplicate pattern.
10298 (&check_configure_ac): Use long options.
10299 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10301 2001-11-26 Akim Demaille <akim@epita.fr>
10303 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10304 Before, having a line containing the opening of a multi line
10305 comment made the whole line be ignored.
10307 2001-11-26 Akim Demaille <akim@epita.fr>
10309 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10310 (testsuite Scripts): Be one of its subsection.
10311 (Autotest Logs): New.
10313 2001-11-26 Akim Demaille <akim@epita.fr>
10315 Test groups are now run two directories deeper.
10317 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10318 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10319 at_top_builddir.
10320 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10321 top_srcdir, builddir and top_builddir.
10322 Use `at_*dir' relatively to the directory containing the
10323 suite, use `*dir' when relatively to the current group dir.
10325 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10327 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10328 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10329 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10330 spelling errors.
10332 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10334 * doc/autoconf.texi (Using System Type): Add an example of `case
10335 $host' usage so people quit using `case $target' everywhere.
10337 2001-11-22 Akim Demaille <akim@epita.fr>
10339 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10340 spotted by Jim Meyering.
10342 2001-11-16 Paul Eggert <eggert@twinsun.com>
10344 This patch implements a `long double' suggestion by Oliver Kiddle.
10346 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10347 static, to catch errors if the value isn't known at compile-time
10348 and the compiler supports dynamic arrays. Change its name from
10349 `_array_' to `test_array' to avoid potential name clashes.
10350 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10351 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10352 better than double. Catch a bug in GCC 2.95.2 x86.
10353 * doc/autoconf.texi (C Compiler): Document the above.
10354 * NEWS: Likewise.
10356 2001-11-13 Akim Demaille <akim@epita.fr>
10358 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10359 hand.
10360 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10362 2001-11-13 Akim Demaille <akim@epita.fr>
10364 * lib/autotest/general.m4 (AT_INIT): After having run the test
10365 group, go back to the initial directory, not to at_suite_dir.
10367 2001-11-13 Akim Demaille <akim@epita.fr>
10369 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10370 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10371 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10372 option.
10373 (AT_CHECK_CONFIGURE): Use absolute paths.
10374 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10375 The problem is still the old one: there is no means in M4 (that I
10376 know about) to create a defining macro, because there is no means
10377 to create `$1' etc., therefore, the defining macro ``swallows''
10378 all the arguments meant to the defined macro.
10380 2001-11-13 Akim Demaille <akim@epita.fr>
10382 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10383 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10384 configure.ac.
10385 * tests/aclocal.m4: Remove, as it is no longer used.
10387 2001-11-13 Akim Demaille <akim@epita.fr>
10389 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10390 variable names when referring to a single test group, or to
10391 `suite' when referring to the whole test suite.
10392 `at_last_test' is removed: m4 compute at_format itself.
10393 (at_stdout, at_stder1, at_stderr): New variables.
10394 (AT_CHECK): Use them.
10396 2001-11-13 Akim Demaille <akim@epita.fr>
10398 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10399 in PATH.
10400 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10401 Do it as soon as a test fails, don't wait till the end of the test
10402 suite.
10403 Don't remove $as_me.[0-9]*, since these files no longer exist.
10405 2001-11-13 Akim Demaille <akim@epita.fr>
10407 * tests/tools.at: Use absolute paths, since we are no longer run
10408 in place.
10410 2001-11-13 Akim Demaille <akim@epita.fr>
10412 Now that tests are running in their own private dir, there is no
10413 need to list the files to remove at the end of tests groups.
10415 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10416 (AT_data_files, at_data_files): Remove.
10417 (AT_CLEANUP, AT_DATA): Simplify.
10418 (AT_INIT): Adjust.
10419 Remove the group dir if !debug && !failed.
10420 * tests/atspecific.m4: Adjust.
10422 2001-11-13 Akim Demaille <akim@epita.fr>
10424 Start a new layout for Autotest: `testsuite' creates
10425 `testsuite.dir' in which the at-check-line etc. files are to be
10426 found, and `testsuite.dir/003' where the test group 3 is run.
10428 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10429 at_check_line_file, at_format, at_test_normalized, at_group_dir
10430 are new variables.
10431 Create the directories.
10432 Use absolute paths for at- files.
10433 (AT_CHECK): Adjust.
10435 2001-11-11 Michael Matz <matz@kde.org>
10437 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10438 (m4_car2): New.
10439 (m4_car): Properly quote arguments.
10441 2001-11-13 Akim Demaille <akim@epita.fr>
10443 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10444 with stricter rules on LIBOBJS.
10446 2001-11-12 Paul Eggert <eggert@twinsun.com>
10448 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10449 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10450 __PROTOTYPES too.
10452 2001-11-12 Akim Demaille <akim@epita.fr>
10454 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10456 2001-11-12 Akim Demaille <akim@epita.fr>
10458 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10459 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10460 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10461 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10462 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10463 specify to what the macro should be defined (typically to 1).
10465 2001-11-12 Akim Demaille <akim@epita.fr>
10467 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10468 From Jim Meyering.
10470 2001-11-12 Akim Demaille <akim@epita.fr>
10472 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10473 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10474 definition used by Automake where LEX is +/- "${missing} lex" and
10475 `missing' itself contains variables.
10477 2001-11-12 Akim Demaille <akim@epita.fr>
10479 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10480 Now that M4sh pushes BODY, the comments were output at the end of
10481 the test suites.
10483 2001-11-08 Akim Demaille <akim@epita.fr>
10485 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10486 that we can trace macros from aclocal.m4.
10487 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10488 obsoleted, and redirect to the former anyway.
10489 Reported by Ralf Corsepius.
10491 2001-11-08 Akim Demaille <akim@epita.fr>
10493 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10494 processed only if present.
10495 * tests/torture.at (Configuring subdirectories): Use autoreconf
10496 instead of successive calls to autoconf.
10497 Add a nonexistent subdirectory to exercise the patch above.
10498 Reported by Ralf Corsepius.
10500 2001-11-08 Kevin Ryde <user42@zip.com.au>
10502 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10503 doesn't accept .S files.
10505 2001-11-07 Akim Demaille <akim@epita.fr>
10507 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10508 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10509 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10510 * bin/autom4te.in (warn_forbidden): New.
10511 (handle_output): Use it.
10512 Read m4_pattern_forbid with messages.
10514 2001-11-05 Akim Demaille <akim@epita.fr>
10516 * bin/autom4te.in (--normalize): Remove.
10517 * lib/autom4te.in: Adjust.
10519 2001-11-05 Akim Demaille <akim@epita.fr>
10521 * tests/Makefile.am (testsuite): Rename this target as...
10522 ($(TESTSUITE)): this.
10523 From Nicolas Joly.
10525 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10527 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10528 the --prefix option, also remove it's argument.
10530 2001-11-05 Akim Demaille <akim@epita.fr>
10532 * doc/autoconf.texi (testsuite Invocation): Update.
10533 (Writing testsuite.at): Update.
10535 2001-11-03 Akim Demaille <akim@epita.fr>
10537 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10539 2001-11-03 Akim Demaille <akim@epita.fr>
10541 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10542 (&file_name_is_absolute): New, wrappers around routines from
10543 File::Spec.
10544 Use and export them.
10545 (&find_configure_ac): Optionally take a directory where to look at.
10546 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10547 the arguments.
10548 Default @ARGV to `.', not find_configure_ac.
10549 (&autoreconf): Argument is a directory.
10550 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10551 * doc/autoconf.texi (autoreconf Invocation): Update.
10553 2001-11-03 Akim Demaille <akim@epita.fr>
10555 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10556 (@export_forward_subs): New.
10557 Add basename, dirname, and fileparse.
10558 (@EXPORT): Adjust.
10559 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10560 Don't look for aclocal flags if we already know aclocal is not
10561 used.
10562 Move aclocal.m4t only if it exists.
10563 Reported by Ezra Peisach.
10565 2001-11-03 Akim Demaille <akim@epita.fr>
10567 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10568 passed on command line, defaulting to ./configure.ac if present.
10569 (&maybe_autoreconf, File::Find): Remove, unused.
10570 (&autoreconf): If autoconf is not used, don't try to trace.
10572 2001-11-02 Akim Demaille <akim@epita.fr>
10574 * configure.ac: Bump to 2.52g.
10576 2001-11-02 Akim Demaille <akim@epita.fr>
10578 Version 2.52f.
10580 2001-11-02 Akim Demaille <akim@epita.fr>
10582 * config/config.guess, config/config.sub, doc/standards.texi:
10583 * config/lispdir.m4: Update from masters.
10584 * configure.ac: Bump to 2.52f.
10586 2001-11-02 Akim Demaille <akim@epita.fr>
10588 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10589 Don't run aclocal when aclocal.m4 is not from aclocal.
10590 From Ezra Peisach.
10591 Don't run libtoolize and gettextize if --install is not given.
10593 2001-11-01 Paul Eggert <eggert@twinsun.com>
10595 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10596 be invoked before _AS_LINENO_PREPARE.
10597 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10598 than character ranges.
10600 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10601 invoking AS_BASENAME. Set the locale variables to 'C' if
10602 possible, as POSIX requires this to get the traditional
10603 behavior.
10604 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10606 2001-10-31 Paul Eggert <eggert@twinsun.com>
10608 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10609 with {}, as that triggers a bug in Bash 2.05.
10611 (_AS_LINENO_PREPARE): Use Sed rather than
10612 Awk. Fix the sed prepass to work even if there are multiple
10613 instances of $LINENO on the same line. Do not substitute for
10614 other variables like $LINENOT. Do not check file dates; such a
10615 check is unreliable on sufficiently fast machines, and removing
10616 the check makes the code simpler and more reliable. Check for
10617 output and chmod failures.
10619 * doc/autoconf.texi (Special Shell Variables): Document
10620 the above.
10622 2001-10-31 Akim Demaille <akim@epita.fr>
10624 * tests/Makefile.am (atconfig): Remove this target, Automake
10625 handles it now.
10627 2001-10-31 Akim Demaille <akim@epita.fr>
10629 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10630 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10631 provided, while it is optional.
10632 * configure.ac: Adjust.
10634 2001-10-26 Paul Eggert <eggert@twinsun.com>
10636 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10637 lib/Autom4te/Struct.pm:
10638 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10639 with 5.005_02.
10641 * doc/autoconf.texi (Special Shell Variables): Document some
10642 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10644 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10645 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10646 eval $LINENO is not portable in practice.
10648 2001-10-24 Akim Demaille <akim@epita.fr>
10650 * lib/Autom4te/General.pm (backname): New.
10652 2001-10-24 Akim Demaille <akim@epita.fr>
10654 * m4/: Remove, merged into...
10655 * config/: here.
10657 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10659 * doc/autoconf.texi (Shellology): Mention the problems with bash
10660 2.05's use of ANSI quoting in its `set' builtin.
10662 2001-10-22 Paul Eggert <eggert@twinsun.com>
10664 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10665 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10666 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10667 POSIX decided to standardize on the int flavor of strerror_r.
10668 Always do char* test, as there's no reason not to.
10669 Assign to a char* var, to catch strerror_r that returns int*.
10671 * doc/autoconf.texi (Particular Functions):
10672 Document the above changes. Also, document the fact that

11126 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
11127 `$LINENO' support replacement when not supported.
11128 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
11129 them explicitly to be sure they are not output before this section
11130 (via m4_require). Cosmetic only.
11131 * lib/autoconf/c.m4, lib/autoconf/general.m4,
11132 * lib/autoconf/programs.m4: Replace all the occurrences of
11133 `__oline__' with `$LINENO'.
11134 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
11136 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
11138 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
11139 character (u: -> ue) in a code comment.
11140 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
11141 it works.
11143 2001-09-21 Akim Demaille <akim@epita.fr>
11145 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
11146 Suggested by Jim Meyering.
11148 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11150 * lib/autoconf/programs.m4: Use extensions listed in
11151 $ac_executable_extensions when looking for programs.
11153 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11155 * lib/autoconf/general.m4: Fix a small Englisho.
11156 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
11157 setting up ac_dir_suffix and ac_top_builddir.
11158 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
11160 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11162 * doc/autoconf.texi (File System Conventions): Clarify the use of
11163 PATH_SEPARATOR.
11164 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
11165 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
11166 be used instead of ':'.
11167 * lib/autotest/general.m4: Replace occurrences of ':' in
11168 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
11170 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11172 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
11173 arguments. Fixed a typo.
11175 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11177 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
11178 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
11180 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11182 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
11183 * bin/autoupdate.in: Ditto.
11184 * bin/autoheader.in: Reworded a few comments.
11185 * bin/autoconf.in: Reworded help text for a few options.
11186 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
11187 * bin/autoscan.in, bin/autoupdate.in: Ditto.
11189 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11191 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
11192 already have $file). Set output files to binary mode (helps avoid
11193 CR issues on DOSish systems).
11195 2001-09-19 Akim Demaille <akim@epita.fr>
11197 * lib/autotest/general.m4: Englishoes.
11198 From Tim Van Holder and Alexey Mahotkin.
11200 2001-09-18 Paul Eggert <eggert@twinsun.com>
11202 * doc/autoconf.texi (Common Shell Constructs): New node,
11203 documenting AS_DIRNAME.
11204 (Limitations of Usual Tools): Refer to it when discussing dirname.
11205 Also, update discussion of POSIX standard to reflect latest draft.
11207 * lib/autoconf/c.m4:
11208 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11210 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11211 Do not pass a first argument with leading '-'
11212 to expr, by parenthesizing initial integers that might be negative.
11214 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11215 now merely checks whether it is an error to pass an argument
11216 to getpgrp.
11218 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11219 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11220 whether it is a (compile-time) error to pass an argument to
11221 getpgrp. This simpler test supports the revised documentation,
11222 and is all that AC_FUNC_GETPGRP's users really need.
11224 2001-09-18 Akim Demaille <akim@epita.fr>
11226 * doc/autoconf.texi (Limitations of Make) <$<>: New.
11228 2001-09-18 Akim Demaille <akim@epita.fr>
11230 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
11231 `{}'.
11232 * lib/autotest/general.m4 (AT_INIT): Adjust.
11234 2001-09-18 Paul Wagland <paul@wagland.net>
11236 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11237 correctly.
11238 Add test for AS_BASENAME.
11239 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11240 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11241 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11242 * tests/base.at: Fixed the expected responses. The old ones were
11243 one line out...
11244 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11245 the documentation claims it should (and how it behaved in 2.13).
11247 2001-09-18 Akim Demaille <akim@epita.fr>
11249 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11250 the AC_CONFIG_COMMANDS invocation.
11251 This also solves the name clash problems.
11252 Don't set the package's ID.
11253 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11254 No longer to be shipped.
11255 (version.in): Remove.
11256 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11257 * lib/autoconf/status.m4: Adjust.
11258 Use `m4_PACKAGE_STRING'.
11259 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11260 the only optional argument is the name of the test suite.
11261 Expect `package.m4' to define the package signature.
11262 * lib/autom4te.in (Autotest): Add `package.m4?'.
11263 * tests/Makefile.am (package.m4): New.
11264 * tests/suite.at: ifnames is a victim.
11266 2001-09-18 Akim Demaille <akim@epita.fr>
11268 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11269 AC_LIBSOURCE, AC_CONFIG_FILES.
11270 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11271 program version string doesn't match the package's.
11272 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11273 after `(cached)'.
11275 2001-09-17 Paul Eggert <eggert@twinsun.com>
11277 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11278 Allow expression to return any value that can fit into unsigned long
11279 (not int, as before). Check for output errors.
11281 2001-09-17 Bruno Haible <haible@ilog.fr>
11283 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11284 Always include <stdio.h> and <stdlib.h>. Evaluate
11285 the expression in an extra function before these includes. Call
11286 fprintf "%d" only after ensuring the argument is of type 'int'.
11287 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11289 2001-09-17 Paul Eggert <eggert@twinsun.com>
11291 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11292 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11293 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11294 when they don't exist.
11296 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11297 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11298 need it.
11300 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11301 version with the version used by fileutils 4.1, except use
11302 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11303 we don't need it.
11305 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11307 2001-09-13 Akim Demaille <akim@epita.fr>
11309 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11310 _first_.
11311 Reported by Gerrit P. Haase.
11313 2001-09-13 Akim Demaille <akim@epita.fr>
11315 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

11322 Use it.

11330 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
11331 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
11332 Likewise.
11333 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)

11335 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
11336 AT_tests_all for consistency.
11337 Set at_victims.
11338 (AT_VICTIMS): Similar to AT_KEYWORDS.
11339 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
11341 2001-09-13 Akim Demaille <akim@epita.fr>
11343 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
11345 2001-09-13 Akim Demaille <akim@epita.fr>
11347 * lib/autotest/general.m4 (AT_INIT): Create and remove
11348 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11349 test suites can cohabit.
11351 2001-09-13 Akim Demaille <akim@epita.fr>
11353 * tests/mktests.sh: Don't output banners for empty test files.
11355 2001-09-13 Akim Demaille <akim@epita.fr>
11357 Test suites can be run independently of configure.
11359 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
11360 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

11403 2001-09-10 Akim Demaille <akim@epita.fr>
11405 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

11438 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
11439 in addition, it introduces useless differences in logs.
11440 (AT_INIT): Let atconfig and atlocal be both optional.
11441 Adjust PATH computation.
11442 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

11453 From Uwe Seimet.
11455 2001-09-05 Akim Demaille <akim@epita.fr>
11457 * bin/autom4te.in: --language is -l, not -s.
11459 2001-09-05 Akim Demaille <akim@epita.fr>

11462 the maintainer is dumb enough to do that...
11464 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11465 excellence in M4 quotation: consider `__file__' is active.
11467 And BTW, when invoking m4, pass the --include in the right order:
11468 the wrong one.
11470 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

11493 2001-09-05 Akim Demaille <akim@epita.fr>

11498 New, extracted from main.
11499 Use IO::File wherever possible.
11500 (input.m4): Be constant, use -I instead of hard coding $tmp.
11501 Therefore be a quoted heredoc.
11502 Don't invoke `_au_disable', since ac was not loaded, but just
11503 `unm4.m4'.
11505 2001-08-31 Akim Demaille <akim@epita.fr>
11507 Version 2.52d.

11528 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11530 2001-08-31 Akim Demaille <akim@epita.fr>
11532 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11533 (testsuite Scripts): There is no such thing as `atconfig.in'.
11534 And actually one diagram is missing: test suite runtime.
11536 2001-08-31 Akim Demaille <akim@epita.fr>
11538 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11539 inverse order.

11543 * bin/autoupdate.in (@include): `installcheck' revealed the path
11544 to m4sugar was lacking!
11546 2001-08-31 Akim Demaille <akim@epita.fr>
11548 * man/Makefile.am (.x.1): We really have to pass
11549 autom4te_perllibdir.
11551 2001-08-31 Akim Demaille <akim@epita.fr>
11553 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11554 debug scripts, in particular passing explicitly listed tests to
11555 run is stupid.
11557 2001-08-31 Akim Demaille <akim@epita.fr>
11559 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11560 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11561 Use directly autom4te, not autoconf.

11577 need for autoconf.
11578 Promote --include over --macrodir and other obsolete options.
11580 2001-08-31 Akim Demaille <akim@epita.fr>
11582 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
11583 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
11584 * bin/autom4te.in ($autoconf): Pass --force.
11585 `print $out' doesn't print `$_' but `$out'.
11586 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11587 (autoheader): Pass --force since the test suite goes too fast for
11588 the time stamps.
11589 Adjust to the new autoheader messages.
11591 2001-08-31 Akim Demaille <akim@epita.fr>
11593 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11594 Check the completeness of the #template.
11595 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
11596 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
11597 invocation.
11599 2001-08-31 Akim Demaille <akim@epita.fr>
11601 * lib/Autom4te/General.pm (&find_file, &update_file): New.
11602 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11603 Drop AC_MACRODIR dead for real.
11604 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11605 `autoheader: `config.hin' is created'.
11606 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11608 2001-08-31 Akim Demaille <akim@epita.fr>
11610 * bin/autoheader.in: Rewrite in Perl.
11611 * tests/autoheader: Adjust.
11613 2001-08-31 Akim Demaille <akim@epita.fr>
11615 * bin/autoconf.in (--include, -I): New option.
11616 Map --localdir, --autoconf-dir onto it.
11617 Forward autom4te's options instead of interpreting them.
11618 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11619 There is no such envvar since the inception of autom4te.cfg.
11620 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11621 * bin/autoupdate.in: Adjust, and perform more control.
11622 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11623 * tests/autoconf: Dittowise.
11625 2001-08-31 Akim Demaille <akim@epita.fr>
11627 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11628 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11629 optionally `FILE'.
11630 Use -e, not -f, since /dev/null for instance is OK.
11631 (&parse_args): Adjust.
11632 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11634 2001-08-31 Akim Demaille <akim@epita.fr>
11636 * configure.ac: Also find tested executables in bin.
11637 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11638 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11639 installed peer executables, only PATH is allowed to resolve it.
11640 Pass `autoconf_dir' via options, not via invisible envvars.
11641 * lib/Autom4te/General.pm (&find_peer): Remove.
11642 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11643 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11644 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11645 find the executables for it.
11646 * tests/Makefile.am: Major cleanup. Too lazy to document...
11647 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11648 We only need PERL.
11649 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11650 indeed related to running the test suite, while passing
11651 --autoconf-dir and others is related to running non installed
11652 Autoconf executables. So don't do that, leave it to...
11653 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11654 * tests/autoscan: New.
11655 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11656 refer to library files: rely on --language.
11658 2001-08-29 Akim Demaille <akim@epita.fr>
11660 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11661 s/--set/--language/.
11663 2001-08-29 Akim Demaille <akim@epita.fr>
11665 * doc/autoconf.texi: Strip the @nodes.
11666 Suggested by Paul Eggert.
11667 (Initializing configure): Typo.
11669 2001-08-29 Akim Demaille <akim@epita.fr>
11671 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11672 Suggested by Paul Eggert.
11674 2001-08-29 Akim Demaille <akim@epita.fr>
11676 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11677 download in a tmp dir.
11679 2001-08-29 Akim Demaille <akim@epita.fr>
11681 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11682 case insensitive OSes out there :(
11683 From Tim Van Holder.
11685 2001-08-29 Akim Demaille <akim@epita.fr>
11687 * lib/autom4te.in: New.
11688 * lib/Makefile.am (edit, autom4te.cfg): New.
11689 * bin/autom4te.in (BEGIN): Simplify.
11690 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.

11692 (&parse_args): Support --mode, --set, and --melt.
11693 * bin/autoconf.in: Simplify and adjust.
11694 * tests/Makefile.am (AUTOMAKE): Use --set.
11695 * tests/atlocal.in: Adjust.
11696 * BUGS: distcheck and check are weak.
11698 2001-08-29 Akim Demaille <akim@epita.fr>
11700 * lib/autotest/general.m4: Use
11701 foo=`(command) 2>/dev/null`
11702 not
11703 foo=`command` 2>/dev/null
11704 (at-devnull): Rename as...
11705 (AT-devnull): this.
11706 (--clean): Remove AT-* files too.
11707 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11708 Reported by Nicolas Joly.

11712 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

11718 * doc/autoconf.texi (Function Portability): Mention C right shifts.
11720 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
11722 * lib/autotest/general.m4: Reword some messages.
11723 (AT_INIT): Check for the `times' builtin before using it.
11724 Support test ranges as arguments to the testsuite.
11725 Have -e imply -d as the help text suggested.
11727 2001-08-27 Akim Demaille <akim@epita.fr>
11729 * Makefile.maint: Formatting changes.
11730 (do-po-update, po-update, cvs-update, update): New targets.

11742 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11743 Support `VAR=VAL' as arguments.

11749 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.

11763 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11764 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11765 readable.
11766 Adjust callers.
11767 * doc/autoconf.texi (Configuration Actions): Document the vars
11768 available in commands.
11769 Emphasize the risks of collisions in init-cmds.

11800 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
11801 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11802 -> ac_dir).
11803 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11804 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11806 2001-08-27 Akim Demaille <akim@epita.fr>

11832 (AMTAR): Help automake define it.

11834 needed, 1.5 can have a macro and a target with the same name.
11835 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
11836 * m4/strip.m4: New.

11849 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
11850 Adjust callers.
11851 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11852 the name of the directory they're in, instead of the filename,
11853 since version.m4 is now in m4sugar, but m4_acversion must not be
11854 classified as an Autoconf macro.
11855 ($input_m4): Don't qualify the path to m4sugar.
11856 Rather, pass autoconf_dir to m4.
11857 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
11858 * tests/suite.at: Require 2.52c.
11860 2001-08-27 Akim Demaille <akim@epita.fr>

11872 of config.log on traps.

11874 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
11875 for config.status'.
11876 Open the log as soon as possible.
11877 Use the same log introduction as configure's.
11879 2001-08-22 Paul Eggert <eggert@twinsun.com>
11881 * doc/autoconf.texi (Indices): New node.
11882 Move indices out of the top level menu and into this submenu.
11884 2001-08-22 Akim Demaille <akim@epita.fr>
11886 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11887 AC_TRY_COMMAND.
11888 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
11890 2001-08-22 Akim Demaille <akim@epita.fr>
11892 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

11929 * configure.ac (AT_CONFIG): Fix the path.

11931 can be used.
11933 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
11935 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
11936 program with AC_LANG_PROGRAM before feeding it to
11937 AC_COMPILE_IFELSE. Cleanup grep usage.
11939 2001-08-20 Akim Demaille <akim@epita.fr>
11941 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11942 * NEWS, README, README-alpha, TODO, tests/README: This package is
11943 `Autoconf', not `autoconf' (the executable).
11945 2001-08-20 Akim Demaille <akim@epita.fr>
11947 Info readers seem to need `Index' in the index node title :(
11949 * doc/autoconf.texi: Reverse the 2001-08-15 change which
11950 simplified index node names.
11952 2001-08-20 Akim Demaille <akim@epita.fr>
11954 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
11955 arguments are not literals.
11956 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
11957 Specify the output variables, and macros defined.
11959 2001-08-20 Akim Demaille <akim@epita.fr>
11961 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
11962 (Examining Syntax) <AC_TRY_COMPILE>
11963 (Examining Libraries) <AC_TRY_LINK>
11964 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
11965 their arguments.
11966 Reported by Werner Lemberg.
11968 2001-08-20 Akim Demaille <akim@epita.fr>

11983 2001-08-20 Akim Demaille <akim@epita.fr>
11985 * lib/autoconf/general.m4 (_AC_OUTPUT_COMMANDS): Say what you do.
11986 * m4/atconfig.m4 (AT_CONFIG): $1 is now the directory where the
11987 test suite lives.
11988 Create `atconfig' automagically.
11989 Configure atlocal.in if present.
11990 * tests/atconfig.in: Remove.

11994 2001-08-20 Akim Demaille <akim@epita.fr>
11996 Huh!?!?! There are still some user EOF tags used, which prevents
11997 their use in AC_CONFIG_COMMANDS for instance...
11999 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
12000 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
12001 `_CSEOF', or `_ATEOF', as appropriate.
12002 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,
12003 * lib/autotest/Makefile.am (check-local): Enforce this constraint.

12218 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12220 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12221 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12222 * doc/autoconf.texi (C Compiler Characteristics): Update
12223 documentation for AC_C_BIGENDIAN.
12225 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12227 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12228 magic values from an object file when cross-compiling.
12229 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12231 2001-08-10 Akim Demaille <akim@epita.fr>
12233 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12234 effects.
12235 Suggested by Russ Allbery.
12237 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12239 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12240 current $prefix to the sub-configures.
12242 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12244 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12245 extension (needed on BeOS). Reported by Guido van Rossum.
12247 2001-08-09 Akim Demaille <akim@epita.fr>
12249 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12251 2001-08-07 Akim Demaille <akim@epita.fr>
12253 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12254 removed.
12255 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12256 No need to remove the files before and after the each test, before
12257 each test and at the end of the suite is enough.
12258 Display only the children `times', not the shell's.
12259 If the test failed or was skipped, at-times is not available.
12261 2001-08-07 Akim Demaille <akim@epita.fr>
12263 Always produce testsuite.log, including when there are no
12264 failures. This helps getting information on skipped tests, and
12265 duration of the tests. Err, implement the latter btw.
12267 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12268 Dump information on the first run of each test.
12269 (AT_CLEANUP): Create `at-times' containing the duration of the
12270 test group.
12272 2001-08-07 Akim Demaille <akim@epita.fr>
12274 The use of `dumpstat' revealed that `len' was used although it
12275 should not. m4_text_wrap was using it, but in the Autoconf world
12276 where it is legal. Hence (i) test M4sh in its own world, not
12277 Autoconf's, and (ii), ahem, fix the bug :)
12279 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12280 does not like `' instead of [].
12281 (AT_INIT): Forbid `^_?AT_'.
12282 And don't output such tokens.
12283 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12284 `script.as', and `autom4te.cache'.
12285 Remove `empty' and `macro' which are no longer used.
12286 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12287 * tests/m4sugar.at: Use it.
12288 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12290 2001-08-07 Akim Demaille <akim@epita.fr>
12292 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12294 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12296 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12298 2001-08-04 Akim Demaille <akim@epita.fr>
12300 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12301 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12302 AC_TRY_LINK.
12303 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12304 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12305 (AC_F77_MAIN): Likewise.
12307 2001-08-04 Akim Demaille <akim@epita.fr>
12309 Don't rely on M4sugar outputting the patterns in files, since we
12310 might process the output _without_ running m4, hence without these
12311 files.
12313 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12314 * bin/autom4te.in (@Request::includes): Remove, unused.
12315 (@Request::source): Rename as...
12316 (@Request::input): this.
12317 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12318 (&handle_output): Fetch the patterns from the traces.
12319 `$forbidden' and `$allowed' are constant: use m//o.
12320 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12321 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12323 2001-08-04 Akim Demaille <akim@epita.fr>
12325 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12326 autoconf', i.e., in addition to caching traces, cache the output.
12328 * bin/autom4te.in (Request::cache): Rename as...
12329 (Request::id): this.
12330 ($cache, $icache, $tcache, $ocache): New.
12331 (&handle_m4): Save M4 output in the cache instead of $tmp.
12332 (&handle_output): Adjust.
12333 (&up_to_date_p): Check that the output cache is up to date too.
12334 (top level): Run `&handle_m4' iff force or the cache is invalid.
12335 Run `&handle_output' if the output cache is more recent.
12337 2001-08-04 Akim Demaille <akim@epita.fr>
12339 * bin/autom4te.in ($force): New.
12340 (&parse_args, &print_usage): -f, --force is a new option.
12341 (&handle_output): CPP directives might have spaces after `#'.
12342 (&parse_args): The first file only can be frozen.
12344 2001-08-04 Akim Demaille <akim@epita.fr>
12346 Don't let autom4te compute the `include' traces several times:
12347 first check that the trace cache file is up to date, and then
12348 compare its timestamp with that of the output.
12350 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12351 the preamble. Don't require 5.005 as Autom4te::General does it,
12352 and better yet (use `use', not `require'!).
12353 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12354 Class::Struct as Autom4te::Struct.
12355 * lib/Autom4te/General.pm (File::stat): Use it.
12356 (&mtime): New, export it.
12357 * bin/autom4te.in: Use it.
12358 Declare `$req' is invalid if it is outdated.
12359 Don't declare it valid before saving it if something went wrong.
12361 2001-08-04 Akim Demaille <akim@epita.fr>
12363 Autom4te shall not encode Autoconf data, and preselecting traces
12364 must be proposed to the users.
12366 * bin/autom4te.in (@required_trace): Remove.
12367 (@preselect): New.
12368 (&parse_args, &print_usage): -p, --preselect is a new option.
12369 (&up_to_date_p): Adjust.
12370 * bin/autoconf.in: Preselect some Autoconf macros.
12372 2001-08-04 Akim Demaille <akim@epita.fr>
12374 * tests/tools.at (autoconf --trace: user macros): Check traces on
12375 macros invoked without arguments, and macros invoked with multiple
12376 lines arguments.
12378 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
12380 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
12381 arguments.
12383 2001-08-03 Akim Demaille <akim@epita.fr>
12385 * bin/autoconf.in ($@): Work around the usual sh bug.
12386 From Nicolas Joly.
12388 2001-08-03 Akim Demaille <akim@epita.fr>
12390 Clean up the handling of the M4 builtins tracing exception.
12392 * bin/autom4te.in (Request::request): Don't complete M4 builtins
12393 trace requests.

12397 (&parse_args): Complete the trace requests with alternate names.
12398 (&handle_traces): Hence no longer do it here.
12399 (&trace_requests): Remove, unused.
12401 2001-08-03 Akim Demaille <akim@epita.fr>
12403 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
12404 m4_if, and m4_wrap.
12406 2001-08-03 Akim Demaille <akim@epita.fr>
12408 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
12409 (m4_divert_pop): Dump the whole diversion stack when a diversion
12410 mismatch happens.
12411 * bin/autom4te.in (&handle_output): Remember of the first
12412 occurrence of a possibly undefined macro, not the last.
12413 Complain about the possibly undefined macros in the same order as
12414 the appear in the output.
12415 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
12416 * tests/tools.at (autoconf: forbidden tokens, basic)
12417 (autoconf: forbidden tokens, exceptions): No longer sort
12418 autoconf's stderr, as it is now deterministic.
12419 Check that `dnl' is caught.
12421 2001-08-01 Akim Demaille <akim@epita.fr>
12423 * configure.ac: Bump to 2.52c.

12437 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
12438 `die'.
12439 (&END): New.
12440 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
12441 `END', as `Autom4te::General::END' will be triggered.
12442 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
12443 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

12835 compiler, not the preprocessor.

12842 2001-07-03 Akim Demaille <akim@epita.fr>

12878 cross-language link tests can be performed successfully.
12879 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12880 after $LIBS, for consistency; this should be the general rule since

12884 2001-06-29 Pavel Roskin <proski@gnu.org>

12887 at-stdout and at-stderr instead of removing the newline
12888 from the echo output, which is not guaranteed to work.
12890 2001-06-28 Jens Petersen <petersen@redhat.com>
12892 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to
