121 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
122 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
123 -Wundef -Werror". Problem reported by David Fang in
124 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
125 * doc/autoconf.texi (Header Templates, Default Includes):

141 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
142 this.
144 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
146 * doc/autoconf.texi (Limitations of Usual Tools): Document sed

168 Fix test suite failures reported by Pierre in
169 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
170 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
171 the compiler created a file "b.out" when it didn't create anything
172 at all.
173 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
174 Discard stderr too, when invoking the test script.

189 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
191 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
192 compiler complains about it, even if things works after the
193 complaint. Problem reported by Peter O'Gorman.
195 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
196 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
197 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
199 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
201 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
202 after -R regardless of host. Patrick Welche reports that this
203 fixes things on NetBSD 3.99.
205 * NEWS: Recommend M4 1.4.5.
206 * README: Likewise.
207 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

209 to match M4 1.4.5.
211 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
213 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
214 under AC_C_VOLATILE.
215 (Volatile Objects): Be a little less skeptical about what
216 "volatile" means. Derived from thoughts by Ben Pfaff in
217 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
219 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
221 * doc/autoconf.texi: Fix some typos.
223 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
225 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
226 more globally, since the 2006-06-30 patch didn't suffice. Problem
227 reported by Keith Marshall. Also, don't bother with builddir2,
228 since it shouldn't be needed any more.
230 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
232 * doc/autoconf.texi (Generic compiler characteristics):
233 Document AC_COMPUTE_INT. Fix wrong statements on Default
234 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
236 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
237 (_AC_COMPUTE_INT): Add obsoletion warnings.

243 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
245 * doc/autoconf.texi (Volatile Objects): New section.
247 * NEWS: Document previous change.
249 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
251 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
252 Require that long long int be at least 64 bits wide. C99 requires
253 this and enough programs depend on it so we should check for it.
254 Bruno Haible reports in
255 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
256 that long long int is 32 bits wide with some nonstandard compilers.
257 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
259 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
261 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
262 to a nonexistent file, so that we don't have to worry about
263 a local site configuration that doesn't use /usr/local.
264 Problem reported by Keith Marshall in
265 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
267 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
269 * doc/autoconf.texi: Be more consistent about using @acronym with
270 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
271 quite right (it talked about "OSF/Tru64", even though the
272 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
273 and it even mentioned "OSF 4"!) and at this point there's little
274 reason to talk about OSF any more, since it died in 1994.
275 (Specific Compiler Characteristics): Simplify example of
276 negative-size array.
277 (File Descriptors): Reorder to make the text flow better.
278 Remove joke about "appreciate the various levels"; I didn't get it.
279 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
280 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
281 (File Descriptors, Limitations of Usual Tools):
282 Tone down the advice against renaming or removing open files.
283 (Limitations of Usual Tools): Add a new section, on 'rm'.
285 2006-06-26 Stepan Kasal <kasal@ucw.cz>
287 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
288 -lXt in LIBS, idea from Karsten Hopp; this was due since
289 this change:
291 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
292 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
293 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
294 (which belong to Xt, not X itself). See Debian bug 327655.
296 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
298 * configure.ac (AC_INIT): Bump to 2.60a.
299 * NEWS: Update.
301 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
303 Version 2.60.
305 * configure.ac, NEWS: Update.
307 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
309 * config/texinfo.tex: Sync from upstream.
311 * bin/autom4te.in (handle_traces): Transform the `@S|@'
312 quadrigraph correctly in traces.
314 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
315 Fix typos.
317 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
318 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
319 not defined.
320 * doc/autoconf.texi (Changed Directory Variables): New node,
321 to document the whole `datarootdir' business a bit better.
322 * NEWS: Update.
323 * tests/torture.at (datarootdir workaround): Extend test.
324 Prompted by report by Alexandre Julliard.
326 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
328 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
329 when using default mode of IBM C 6 for AIX. Problem and two-line
330 fix reported by Larry Jones.
332 2006-06-22 Alexandre Julliard <julliard@winehq.org>
334 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
335 about literal '${datarootdir}' if a definition is found in the
336 output file.
338 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
340 * NEWS: Use "M4" rather than "m4" when appropriate.
341 Problem reported by Eric Blake.
342 * doc/autoconf.texi: Likewise.
343 Use @acronym around BSD, GCC, and GNU when appropriate.
344 (Why GNU M4): Renamed from "Why GNU m4".
345 (Redefined M4 Macros): Mention that Posix
346 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
347 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
348 to int.
350 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
352 * bin/autom4te.in (handle_output): Do not forbid the empty
353 pattern.
354 * tests/tools.at (autoconf: the empty token): New test.
356 2006-06-20 Stepan Kasal <kasal@ucw.cz>
358 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
359 calls, so that we do not care whether they are LIFO or FIFO;
360 in the m4_wrap, do not check which diversion is the topmost
361 one, just check that the stack is balanced at the end.
362 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
363 base diversion forever--pop the previous diversion before
364 opening the new one; consequently, remove the m4_wrap call.
365 * lib/autotest/general.m4 (AT_INIT): Likewise.
366 * tests/m4sugar.at: Do not use
367 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
369 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
370 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
372 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
373 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
374 Rework example of m4wrap token-pasting trouble so that it doesn't
375 care whether it's LIFO or FIFO.
376 Fix some "contrary to"s that are awkward in English.
378 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
380 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
381 to `yes' instead of `int$1_t' if the type is found, for more
382 consistent configure output (where $1 is the number of bits).
383 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
384 Suggested by Bruno Haible.
386 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
387 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
388 with system headers. Report by Bruno Haible.
390 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
392 * config/config.guess, config/config.sub: Sync from upstream.
394 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
395 in order to avoid picking up an older installed frozen m4sh.m4f.
396 Besides an outdated shell startup, this could have been created
397 by an earlier M4 version with incompatible frozen file format.
399 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
401 * README: Recommend m4 1.4.4 instead of 1.4.3..
402 * doc/autoconf.texi: Likewise.
403 (Special Chars in Names): Say that $(.FOO) is portable, as
404 suggested by Stepan Kasal.
405 (Installation Directory Variables, Build Directories):
406 (Automatic Remaking, Subdirectories, Fortran Compiler):
407 (Making testsuite Scripts, Defining Directories):
408 Quote variable usages better.
409 (Making testsuite Scripts): Add clean-local rule to makefile
410 snippet, by Eric Blake.
411 (Installation Directory Variables): Fix table item font.
412 Reword slightly to clarify. Generalize advice about
413 not using special characters to include all file-related
414 vars, not just VPATH.
415 (Special Chars in Variables): Warn about special characters in
416 $(srcdir) too.
417 (Assignments): Clarify default-value example as suggested by
418 Ralf Wildenhues in
419 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
420 (Special Shell Variables): Note leading ./ or ../, as suggested
421 by Eric Blake.
422 (Limitations of Builtins): Under cd, warn about CDPATH.
423 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
424 Ralf Wildenhues.
426 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
428 * doc/autoconf.texi (Configuration Actions): Remove duplicate
429 `@var', for texi2html.
430 (Systemology): Some more word wrapping, for DVI output.
431 (autom4te Invocation): The short option for `--melt' is `-M',
432 not `-m'.
434 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
436 * doc/autoconf.texi: More formatting and English tweaks,
437 many suggested by Ralf Wildenhues.
438 Reword to avoid "@code{...}'s" and the like, since it's ugly
439 with Emacs info mode. discontents -> woes.
440 Put a few "will"s back. time stamp -> timestamp.
441 side-effect -> side effect.
443 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
445 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
446 Warn about $@ not persisting. Problem reported by Julien Danjou in
447 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
448 (Special Chars in Names): Renamed from Leading _ in Macro Names.
449 Mention other special chars, too.
451 2006-06-14 Eric Blake <ebb9@byu.net>
453 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
455 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
457 * doc/autoconf.texi: Some systematic minor improvements, as
458 follows. Use "makefile" when talking about makefiles
459 generally (which might be named "makefile" or "Makefile" or even
460 "foo.mk"), "Makefile" when talking about a specific makefile
461 called "Makefile". This unclutters the text from weird quotes
462 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
463 values" rather than "@var{foo}s" and similar constructs containing
464 "}s". Use "Make rules" rather than "Makefile rules". Minor
465 English-language improvements. Change the prefix "sub-" to "sub"
466 and "re-" to "re".
467 Put blank lines around examples more consistently.
468 Avoid "rather" and "very" as intensifiers.
469 Avoid "will" as an auxiliary.
470 (Limitations of Make): Split this node into....
471 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
472 (Leading _ in Macro Names, Backslash-Newline-Newline):
473 (Backslash-Newline Comments, Long Lines in Makefiles):
474 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
475 (obj/ and Make, make -k Status, VPATH and Make):
476 (VPATH and Double-colon, $< in Explicit Rules):
477 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
478 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
479 New nodes, resulting from splitup of Limitations of Make.
480 All cross-references changed. Raise the top node from
481 a section to a chapter, and all subnodes accordingly.
482 Redo the introductory wording to match the new organization.
483 (Installation Directory Variables): Use an example that is
484 closer to what Autoconf actually does. Mention that VPATH's
485 value should not contain metacharacters or white space.
486 (Fortran Compiler): Fix a VPATH bug in an example.
487 (Leading _ in Macro Names): Mention that this problem is no longer
488 of practical concern.
489 (VPATH and Make): Reword the advice to make it clearer
490 that Autoconf and Automake support VPATH in non-GNU make, but
491 many packages have bugs in this area.
492 ($< in Explicit Rules): Refer to Build Directories rather
493 than using a (non-VPATH-safe) example.
494 (Automatic Rule Rewriting): Mention the sort of disaster that
495 can ensue with Solaris-style rule rewriting with VPATH.
497 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
499 * doc/install.texi (Compilers and Options): Weaken the

510 * doc/autoconf.texi (Installation Directory Variables):
511 Drop extra @samp from `@table @samp' item.
512 (Limitations of Usual Tools): Comment fix.
513 Do not nest @samp just to point to other table items.
514 (Writing testsuite.at) <AT_CHECK>: The second argument to
515 `@dvar' is already @samp'ed.
516 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
517 do not use @var in the second argument.
519 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
521 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
522 $as_shell.exe too. Problem reported by Andreas Buening in
523 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
525 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
527 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
528 `unused variable' compiler warning, for `-Wall -Werror'.
529 Reported by Jaap Haitsma in
530 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
532 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
534 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
535 case the compiler dumps core. Problem reported for
536 OpenServer 5.0.7 by Tim Rice in
537 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
538 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
539 Likewise.
541 2006-06-06 Tim Rice <tim@multitalents.net>.
543 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
544 "ERROR" only shows up in "make check" output if there is an
545 error.
547 2006-06-06 Eric Blake <ebb9@byu.net>
549 * tests/tools.at (automatically allowed tokens): Fix typo.
551 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
553 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
555 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
556 typically overflows on x86 CPUs, even though the C standard
557 requires otherwise.
559 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
561 * configure.ac (AC_INIT): Bump to 2.59e.
562 * NEWS: Update.
564 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
566 Version 2.59d.
568 * config/texinfo.tex: Sync from upstream.
570 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
571 seen, invoke libtoolize with `--ltdl' argument.
572 * lib/autom4te.in (Autoreconf-preselections): Adjust.
573 * NEWS: Update.
574 Suggested by Eric Blake.
576 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
578 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
579 reported by Ralf Wildenhues.
580 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
582 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
584 * THANKS: Update.
586 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

593 message issued by AC_REQUIRE.
594 * tests/m4sugar.at: Check m4_require's error message.
595 * tests/base.at: Check AC_REQUIRE's error message.
596 * tests/local.at (AT_CHECK_M4): New macro, almost identical
597 to...
598 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
599 AT_CHECK_M4.
600 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
601 `expout' as the last parameter.
602 * tests/tools.at: Adapt to the above change.
604 2006-06-04 Stepan Kasal <kasal@ucw.cz>
606 * doc/autoconf.texi (Limitations of Usual Tools): Correct
607 information about race-free implementations of mkdir.
609 2006-06-04 Eric Blake <ebb9@byu.net>
611 * bin/autoreconf.in (help): Document M4 environment variable.
612 * bin/autoconf.as (Usage): Likewise.
613 * bin/autom4te.in (help): Likewise.
614 * doc/autoconf.texi (autom4te Invocation): Likewise.
616 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
618 * NEWS: GNU make now recommended for VPATH builds.
619 Mention that some macros are now documented to be obsolescent.
620 * doc/autoconf.texi:
621 Prefer "current" to "modern" to describe
622 currently-used (albeit perhaps old-fashioned) hosts.
623 Mention which ancient features no longer need to be worried about.
624 setgid -> set-group-ID
625 setuid -> set-user-ID (these are the Posix terms)
626 Fix some misuses of "only".
627 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
628 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
629 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
630 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

633 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
634 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
635 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
636 Mention that these macros are obsolescent.
637 (Installation Directory Variables): shall -> should
638 (File Descriptors): Mention that 0, 1, 2 might get reopened.
639 Mention that it's now safe to use 3 and 4.
640 (Limitations of Usual Tools): cp -r is now specified by Posix.
641 Omit longwinded and obsolescent discussion of cp -f.
642 Modernize discussion of expr, ls.
643 (Limitations of Make): Modernize discussion of VPATH builds.
644 Mention $? as a workaround in some cases.
645 * doc/install.texi (Basic Installation):
646 Mention "./configure; make; make install" first. Be more
647 specific about why this file is generic. Remove unnecessary
648 parens. Remove misleading "only". Remove obsolete advice
649 about csh. Don't say "configure" takes awhile; say it
650 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
651 and CC=c99 rather than CC=c89, as these are blessed by current
652 Posix. Recommend GNU make if doing a VPATH build.
654 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
656 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
657 examples involving shell prompts.
659 2006-06-02 Stepan Kasal <kasal@ucw.cz>
660 and Paul Eggert <eggert@cs.ucla.edu>
662 * doc/autoconf.texi (Here-Documents): Add details about the
663 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
664 use "here-documents" instead of "here documents".
666 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
668 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
670 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
672 * doc/autoconf.texi (File System Conventions): Warn about ":"
673 anywhere in directory names.
675 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
677 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
678 about quoting the case statement, just in case.
679 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
680 was fixed in ksh93g; reported by Ralf Wildenhues.
682 2006-05-31 Stepan Kasal <kasal@ucw.cz>
684 * doc/autoconf.texi (System Services): Do not document
685 overriding EXEEXT via ac_cv_exeext=ext.
686 (Particular Programs) <AC_PROG_MKDIR_P>:
687 Document that ${MKDIR_P} understands --.
688 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
689 comment.
691 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
693 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
694 argument with leading hyphen. Problem reported by Paul Eggert.
696 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
698 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
699 about quoting ac_try: quote all of it, if any of it seems suspicious.
700 This means we don't have to worry about ${ or sed any more.
701 Also, double-quote the case statement, to work around misuses via
702 underquoting as reported by Ralf Wildenhues in
703 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
704 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
705 undocumented and dangerous macro.
706 Problem reported by Ralf Wildenhues in
707 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
709 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
711 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
712 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
713 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
715 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
717 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
718 since evidently some packages rely on the old, broken behavior.
719 Problem reported by Ralf Wildenhues in
720 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
721 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
722 pre-2006-05-26 definitions, but leave in the comments that
723 these macros are dangerous and should not be used.
724 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
725 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
726 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
727 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
728 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
730 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
732 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
733 the use of 'tr', since this is our only use of 'tr'.
735 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
736 and Paul Eggert <eggert@cs.ucla.edu>
738 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
739 Don't assume 'grep' works on long lines, since AIX grep doesn't.
741 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
743 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
744 the output file in the `${datarootdir}' test.
746 2005-05-28 Stepan Kasal <kasal@ucw.cz>
747 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
749 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
750 mention of `datarootdir' in the input file(s), but literal
751 `${datarootdir}' in the output file, and we haven't warned yet,
752 then warn as well: the user may have (erroneously) used
753 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
754 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
755 * tests/torture.at (datarootdir workaround): Extend this test.
756 * NEWS: Update.
758 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
759 and Paul Eggert <eggert@cs.ucla.edu>
761 * doc/autoconf.texi (autoheader Invocation): The first argument to
762 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
763 alternatives and clear up the language a bit.
765 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
767 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
768 ac_config_guess, ac_config_sub, ac_configure.
769 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
770 Fix typo that prevented an unnecessary space from being removed.
771 Problems reported by Ralf Wildenhues in:
772 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
774 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
776 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
777 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
778 Don't use the term "thread-safe" to talk about mkdir race
779 conditions, since the problem is more a process than a thread
780 issue. Problem reported by Stepan Kasal in:
781 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
782 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
783 the test for 'install' more closely. Look at MKDIR_P first.
784 Look in the PATH, and at /opt/sfw/bin.
785 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
786 Don't bother to try mkdir -p, since we already check mkdir --version;
787 just look at the version number. (There's no easy way to check
788 for race-free implementations.)
789 * tests/tools.at (autoconf: subdirectories): Adjust to above
790 changes, since MKDIR_P now might end in "/mkdir -p".
792 * doc/autoconf.texi (autoheader Invocation): Mention that the
793 first arg of AC_DEFINE_UNQUOTED must be a literal.
794 Problem reported by Ben Pfaff in
795 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
797 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
798 * doc/autoconf.texi (Special Chars in Variables): New section.
799 (Preset Output Variables): Warn about special chars in CPPFLAGS.
800 (Installation Directory Variables): Quote $(datadir) better.
801 (Limitations of Builtins): Describe some of eval's trickiness.
803 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
804 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
805 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
806 in front of every arg, not just trailing args. Quote apostrophes.
807 (_AC_EVAL_ECHO): New macro.
808 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
809 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
810 removed.
811 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
812 exposed by quoting of eval argument. Put the command on line line
813 so it logs better.
814 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
815 (_AC_PATH_X, AC_PATH_X): Quote more safely.
816 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
817 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
818 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
819 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
820 Use eval more safely.
821 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
822 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
823 to be replaced.
824 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
825 lines, exposed by quoting of eval argument.
827 2006-05-26 Stepan Kasal <kasal@ucw.cz>
828 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
830 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
831 initialization of `ac_cv_exeext', do not override it if it was
832 already set, unless it was set to `no', for compatibility with
833 Autoconf-2.13, and comment this.
834 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
835 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
836 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
837 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
838 Document that this test may be overridden by setting
839 `ac_cv_exeext'.
841 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
843 Revert these two patches:
845 2006-04-06 Eric Blake <ebb9@byu.net>
846 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
847 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
848 2006-04-01.
850 2006-04-01 Stepan Kasal <kasal@ucw.cz>
851 Clean up _AC_COMPILER_EXEEXT* macros.
852 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
853 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
854 ac_file to the name of the default output file and call
855 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
856 initial `rm' of the candidate files...
857 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
858 the same list in subsequent `rm' calls, and for the temporary
859 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
860 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
861 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
862 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
863 no longer needed) by libtool. Make it a cache check.
864 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
865 copied here by mistake.
866 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
867 _AC_COMPILER_EXEEXT.
868 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
869 _AC_COMPILER_OBJEXT directly.
870 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
872 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
874 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
875 Fix description of how the buggy `sed' works.
877 2006-05-25 Noah Misch <noah@cs.caltech.edu>
879 Sync from Automake:
881 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
882 ENOLCK. Only mention `make -j' when applicable. Only raise
883 fatal errors when `make -j' is involved. Improve error message.
885 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
887 * doc/autoconf.texi (Here-Documents): We now know more about
888 the variable expansion in here documents bug.
889 Thanks to Tim Rice and Stepan Kasal.
891 * doc/autoconf.texi (Making testsuite Scripts): Add an example
892 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
894 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
896 * tests/autotest.at (Multiline command from M4 expansion):
897 No failure to be expected if the shell quotes newlines in
898 commands in the `set -x' output. Report by Tim Rice.
899 * THANKS: Update.
901 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
903 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
904 expansion in the here-documents used by config.status, as that
905 runs afoul of the Korn shell version M-12/28/93d bug described in
906 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
907 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
908 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
910 2006-05-23 Jim Meyering <jim@meyering.net>
912 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
913 Fix typo introduced with 2006-04-02 change. It reversed the sense
914 of the test.
916 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
918 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
919 ac_dB slightly, to save bytes in the script.
920 Max out at 50 lines, rather than 96; this is more likely
921 (though not guaranteed) to avoid obscure 'sed' failures.
923 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
925 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
926 `tr -d -' as bad option argument. Work around this by deleting
927 an unrelated character.
928 Report by Tim Rice <tim@multitalents.net>.
930 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
931 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
932 Stepan Kasal <kasal@ucw.cz>
934 * doc/autoconf.texi (Particular Programs): Do not promise that
935 we always prefer the GNU version of the program, and that we
936 search according to PATH; both rules can have exceptions.
937 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
938 AC_PROG_SED. Move descriptions of limitations
939 to the Limitations of Usual Tools section.
940 (Limitations of Usual Tools) <sed>: Mention script length
941 limitations with Solaris /usr/ucb/sed.
942 <grep>: Fix wording for empty alternative. Mention that -c and
943 -l should not be combined, and that -E and -F should not be
944 combined.
946 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
947 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
949 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
950 limits in Solaris 8 /usr/ucb/sed by testing a long script.
952 2006-05-22 Stepan Kasal <kasal@ucw.cz>
954 * doc/autoconf.texi (Defining Symbols): Literal parameter of
955 AC_DEFINE is now passed to m4_pattern_allow.
956 * NEWS: Mention that; likewise for AC_SUBST.
957 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
958 the parameter to m4_pattern_allow.
959 * tests/tools.at: Add a check for that.
961 2006-05-22 Stepan Kasal <kasal@ucw.cz>
963 * lib/autoconf/status.m4: Fix typos.
965 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
967 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
968 only the files that this macro generates.
970 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
972 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
973 the HP-UX sed limitation of 99 commands, labels do not count.
974 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
975 in the comment.
976 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
978 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
980 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
981 Import the following fix from coreutils:
983 2006-01-13 Jim Meyering <jim@meyering.net>
985 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
986 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
987 not double-quote uses of that variable, to accommodate the rare
988 case in which getmntent is available in none of the libraries
989 checked. This happens at least on FreeBSD 5.0.
991 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
993 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
994 ac_config_guess, ac_config_sub, and ac_configure, since evidently
995 some other programs unwisely rely on these undocumented vars.
996 But put in warning comments about them.
997 Problem reported by Ralf Wildenhues in
998 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
999 * NEWS: Document that these variables are intended to go away.
1001 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1003 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1004 and set the language to C++ (analogous to the equivalent Fortran
1005 tests).
1007 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1008 * doc/autoconf.texi (C++ Compiler): Document it.
1009 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1010 * NEWS: Update.
1012 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1014 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1015 that caused config.status to generate 100-command sed scripts; the
1016 portable limit is 99.
1018 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1020 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1021 variable `ac_d' instead of `d' to avoid infringing namespace.
1022 Report by Ralf Menzel.
1024 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1026 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1027 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1028 * tests/tools.at (autoconf: subdirectories): New test, taken from
1029 the corresponding problem report by Ralf Wildenhues in:
1030 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1032 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1033 Quote some uses of shell variables if they might suffer unexpected
1034 globbing. This doesn't fix all instances of quoting problems that
1035 I found, just the easy ones that look safe.
1036 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1037 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1038 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1039 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1040 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1041 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
1042 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
1043 Likewise.
1044 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
1045 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1047 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1049 * bin/autoreconf.in ($help): Reword according to the manual.
1050 Suggested by Olly Betts.
1052 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1053 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1055 * bin/autoreconf.in: Pass the directory argument to
1056 `require_configure_ac'. Fix comment.
1057 * tests/torture.at (Configuring subdirectories): Expose this.
1058 Reported by Olly Betts.
1060 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1062 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1063 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1064 Automake as follows:
1066 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1067 `$configure_in' instead of `configure.in', to preserve
1068 directory component.
1070 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1072 * config/config.guess, config/config.sub, config/texinfo.tex,
1073 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1075 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1077 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1078 test for C99 conformance; (bool) 0.5 is an integer constant
1079 expression, but (bool) -0.5 is not. Problem reported by Fedor
1080 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1082 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1084 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1085 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1086 Warn about obsolete install-sh files. Remove stray sentence
1087 fragment and fix cross reference.
1088 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1089 install -d; this undoes the 2006-05-10 change.
1090 (MKDIR_P): Mark with AN_MAKEVAR.
1091 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1092 that we don't require $INSTALL to be thread-safe. Move comments
1093 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1094 of AC_PROG_INSTALL. Output a message saying that we're checking
1095 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1096 MKDIR_P instead of AC_SUBST.
1097 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1098 Special magic for MKDIR_P, too.
1099 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1100 a dnl.
1101 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1103 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1105 Sync from Automake, as follows:
1107 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1108 * config/install-sh: Initialize IFS, so field splitting isn't
1109 turned off later.
1110 * config/mkinstalldirs: Likewise.
1111 * config/missing: Remove superfluous quotes. Replace all uses of
1112 `[' by `test', for consistency, and for..
1113 * config/missing (sed_minuso, sed_output): New variables.
1114 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1115 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1116 Fixes `missing' to detect `--output' for help2man. Fixes
1117 PR automake/483. Report by Dennis J. Linse.
1118 (autom4te): Document in `missing --help'.
1120 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1122 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1123 * config/install-sh: Don't use 'path' to talk about file names,
1124 as per GNU coding standards. Close a race condition reported by Ralf
1125 Wildenhues and Stepan Kasal. There is still a race condition
1126 on hosts that predate Posix 1003.1-1992, but we can't help this.
1127 Don't mishandle weird characters like space on pre-Posix hosts.
1128 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1129 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1130 AC_PROG_MKDIR_P from AS_MKDIR_P.
1131 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1132 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1133 earlier editions are not (including Automake 1.8.3).
1134 Do not suggest mkinstalldirs for thread-safety.
1135 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1136 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1137 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1138 presence of special characters and race conditions.
1139 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1140 in Autoconf's name space.
1142 2006-05-10 Bruno Haible <bruno@clisp.org>
1143 and Paul Eggert <eggert@cs.ucla.edu>
1145 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1146 from Automake with minor changes.
1147 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1149 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1151 * config/install-sh: Update to Automake CVS version, as follows:
1152 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1153 * lib/install-sh: Simplify the expr implementation of dirname.
1154 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1155 * lib/install-sh: Handle --, and diagnose unknown options.
1157 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1159 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1160 `./autom4te' to create `./testsuite', since the `all' target
1161 will ensure its presence, but `installcheck' should not create
1162 the uninstalled wrappers.
1164 * tests/torture.at (Unusual Automake input files): Skip if we
1165 detect automake < 1.8.
1167 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1169 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1170 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1171 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1172 * NEWS: Update.
1174 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1176 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1177 munge (multiple) white space and other oddities.
1178 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1179 single quotes in variable assignment.
1180 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1181 and similar failures by adding multiple spaces, tabs, and other
1182 special characters.
1183 Report and different test suggested by Francesco Romani
1184 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1186 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1187 single quotes, we only need to search for single quotes; this
1188 both simplifies the search pattern, and makes us less
1189 susceptible to `echo' variations for arguments not containing
1190 single quotes.
1191 (_AC_ARG_VAR_VALIDATE): Likewise.
1193 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1195 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1196 `$*' and IFS concatenation issue with traditional shells and
1197 bash-2.04. Report by Seanster@Seanster.com.
1199 2006-05-03 Bruno Haible <bruno@clisp.org>
1201 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1202 precisely which Mac OS X versions have the od problem.
1204 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1206 * doc/autoconf.texi: Use @option systematically.
1208 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1209 and Bruno Haible <bruno@clisp.org>
1211 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1212 about 'od'.
1213 (Integer Overflow): Mention the special case of integer division
1214 overflow.
1216 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1218 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1219 traditional shells like the Solaris one that do not use the
1220 first IFS character for assembling `$*'.
1221 Prompted by a related report from autoconf_bug@nro.ca.
1223 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1224 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1226 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1227 Mention more problems with the -e option.
1229 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1231 * NEWS: Typo.
1232 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1234 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1235 in URLs to improve DVI formatted output (requires texinfo 4.6).
1236 (System Services, Systemology, Shellology): Likewise.
1237 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1238 output.
1240 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1241 continuous text.
1242 (Runtime): Fix macro argument names to match description:
1243 `action-if-found' -> `action-if-true' and similarly.
1244 (Obsolete Macros): Likewise.
1245 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1246 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1247 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1249 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1251 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1253 * ChangeLog: Typo.
1254 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1255 DVI output.

1266 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1267 (Integer Overflow, Null Pointers, Buffer Overruns):
1268 (Floating Point Portability, Exiting Portably): New sections.
1269 (Writing Test Programs): Fix some langauge. Recommend exiting
1270 with status 1, not merely nonzero. Clarify exit declaration.
1271 (Run Time): Move C exit status stuff to new Exiting Portably section.
1272 (Systemology): Mention Posix and levenez. Update v7 reference.
1273 (Portable Shell): Mention the Posix shell.
1275 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1277 * bin/autoconf.as (me): Replace by as_me.
1279 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1281 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1282 since as_me isn't set yet.
1284 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1286 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1287 a few minor bugs in this area.
1289 * doc/autoconf.texi (Programming in M4sh): Comment out the
1290 documentation of AS_BASENAME, for now.
1291 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1292 (Limitations of Builtins) <basename>: Do not refer to
1293 AS_BASENAME.
1294 * bin/autoconf.as (me): Don't use AS_BASENAME.
1295 (dir): Remove the unused variable.
1296 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1297 AS_DETECT_REQUIRED. All uses changed.

1299 All uses changed.
1300 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

1303 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1304 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1305 (_AS_DIRNAME_PREPARE): Likewise.
1306 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1307 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1308 (AS_DIRNAME): Use "dirname --".
1310 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1312 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1313 of "run time" and "run-time" changed to "runtime", for consistency.

1320 with more accuracy and detail.
1322 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1324 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1325 Archive is not officially `GNU' any more. Update URL.
1326 (Defining Directories): Likewise
1327 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1329 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1331 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1332 newline from the `trap' code to finish `config.log'; the NetBSD
1333 /bin/sh resets the exit status after an empty command, as
1334 documented in doc/autoconf.texi.
1335 Reported by Dalibor Topic <robilad@kaffe.org>.
1337 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1339 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1340 Suggested by Bruno Haible.
1342 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1344 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1345 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1346 Instead, just list the shells that we know work.
1347 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1348 changed. Be more cautious about the _cv_ variable.
1349 * tests/tools.at (Syntax of the shell scripts): Check the
1350 _cv_ variable once, at first, to avoid an internal autoconf error
1351 when sh -n does not work.
1353 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1355 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1357 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1359 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1360 use ">&-" since we're only 99.999% sure that this is portable,
1361 and since the MinGW bug is fixed in a different way.
1362 * lib/autotest/general.m4 (AT_INIT): Likewise.
1364 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1366 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1367 before opening config.log, to avoid hitting a bug on MinGW.
1369 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1371 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1372 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1373 This works around a MinGW bug reported by Eric Paire.
1374 Make sure that all writes to the log file append to it,
1375 rather than possibly losing data.
1376 * lib/autotest/general.m4 (AT_INIT): Likewise.
1378 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1380 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1381 description.
1383 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1385 * NEWS: Update.
1387 * configure.ac (AC_INIT): Bump to 2.59d.
1389 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1391 Version 2.59c.
1393 * Makefile.maint (news-date-check): Do not require a leading `*'
1394 before the release date in NEWS.
1396 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1397 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1399 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1400 the instantiated file do not contain the string 'datarootdir'
1401 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1402 @mandir@, replace the reference '${datarootdir}' by the value.
1403 * tests/torture.at (datarootdir workaround): New test.
1404 * NEWS: Advertise this temporary fixup.
1405 Based on a patch by Bruno Haible, reported and analyzed by
1406 Paul Eggert and Noah Misch.
1408 2006-04-12 Eric Blake <ebb9@byu.net>
1410 * tests/autotest.at (Debugging a failed test): Fix comment.
1412 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1414 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1415 all the changes since 2006-04-07.
1417 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1419 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1420 succeeded, but `ln -s file dir' failed, take care to remove the
1421 leftover target before the next test, to prevent its spurious
1422 failure; also make sure `ln file dir' works before selecting it.
1423 Thanks to Keith Marshall for pointing this out.
1424 * THANKS: Update.
1426 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1427 assignments in `at_debug_args', so that we put them correctly
1428 in the `run' script.
1429 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1430 Reported by Eric Blake.
1432 2006-04-11 Eric Blake <ebb9@byu.net>
1434 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1435 top-level tests after micro-suite has been run. Used in...
1436 (Debugging a successful test, Debugging script and environment),
1437 (Debugging a failed test): ...these new tests. The first of these
1438 is fixed by...
1439 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1440 macro, split out from...
1441 (AT_INIT): ...here, so that using -d also generates a run script.
1442 Document that -d inhibits top-level logging.
1443 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1444 inhibits top-level logging; debug scripts are created.
1446 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1447 check.
1448 * tests/autotest.at (Empty test, Empty check): New test to check it.
1450 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1451 from gcc.
1453 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1455 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1456 the files if a problem appears. Make the empty *.at files
1457 read-only, too. Proposed by Ralf Wildenhues.
1459 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1461 * config/Makefile.am: Add comment to force updated Makefile.in.
1463 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1464 space only patch to this file, this patch causes the Makefile.in
1465 files that include freeze.mk to be updated, and thus have a
1466 newer time stamp again, which in turn makes a pristine CVS
1467 checkout have correct time stamps.
1469 * Makefile.maint (cvs-sv): New macro, to be used..
1470 (config.guess-url_prefix, config.sub-url_prefix)
1471 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1472 point to CVS text checkout of Gnulib files.
1473 (copyright-check): Bump current year.
1474 (announcement): Do not hard-wire `./announce-gen'.
1475 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1476 correctly.
1477 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1478 `chmod +x'.
1479 (wget_files): Update config.guess, config.sub, texinfo.tex by
1480 `wget-update', now that their URLs work again.
1482 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1484 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1485 Problem noted by Paul D. Smith.
1487 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1489 * doc/autoconf.texi: Remove unused words from word list.
1490 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1491 .x-sc_trailing_space: New files.
1493 * doc/standards.texi: Sync from gnulib.
1495 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1496 `LIBOBJDIR' as experimental.
1498 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1499 with a target directory; it's internally implemented as `cp'
1500 anyway, but since Autoconf advertises the possibility to use
1501 a target directory when LN_S is `ln -s', we need to find out.
1502 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1503 analyzed by Keith Marshall <keith.marshall@total.com>.
1505 * THANKS: Update.
1507 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1509 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1510 confdefs.h as-is. In general, if it has backslash-newline or the
1511 like, then it doesn't work either to sort or to remove empty
1512 lines.
1514 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1516 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1518 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1520 * lib/autom4te.in (Automake-preselections): Preselect
1521 _AM_SUBST_NOTMAKE.
1523 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1525 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1526 apostrophe within a single-quoted string, as this is the usual
1527 tradition and is easier to read than '"'"'. Don't rely on the
1528 shell treating "$/" like '$/'. Use a more-consistent indenting
1529 style for the trap.
1531 2006-04-09 Eric Blake <ebb9@byu.net>
1533 * tests/autotest.at (Backquote command substitution),
1534 (Multiline backquote command substitution): Remove mistaken
1535 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1536 applied...
1537 (Parenthetical command substitution, Multiline parenthetical
1538 command substitution): here.
1540 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1542 Import macros from gnulib (often changing their name).

1558 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1559 Gnulib section.

1564 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
1565 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

1568 headers too.
1569 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1570 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1571 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1572 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1573 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1574 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1575 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1576 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1577 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1578 (Coding Style). Don't mention m4_expand_once.
1579 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
1580 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
1581 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
1582 (AC_CHECK_FUNCS): Use it.

1587 (AC_HEADER_ASSERT): New macro.
1588 (AC_HEADER_STDBOOL): Don't assume "#error" works.
1589 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
1590 Catch a bug in an HP-UX C compiler.
1591 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
1592 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
1593 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
1594 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):

1596 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
1597 New macros.
1599 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
1600 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
1602 2006-04-08 Stepan Kasal <kasal@ucw.cz>
1604 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1605 of the warning introduced by the 2001-08-28 change.
1607 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
1608 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1610 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
1611 variables shall be overriden by the cache.

1613 that contains braces.
1615 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1617 Revert the patch from 2006-04-01 and only improve
1618 _AS_DETECT_BETTER_SHELL:
1620 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1621 skip nonexistent directories.
1622 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1623 only shell candidates which exist.
1624 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1625 * lib/autotest/general.m4 (AT_INIT): No need to give three
1626 parameters to _AS_PATH_WALK.
1628 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1629 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1631 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1632 distinguish m4sugar macros.
1633 * tests/tools.at (autoupdating with aclocal and m4_include):
1634 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1635 test case by Noah Misch <noah@cs.caltech.edu>.
1637 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1639 Revert my change from 2006-03-17, in other words:
1640 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1641 and DUALCASE=1.
1642 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1643 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1644 it is set.
1646 2006-04-07 Eric Blake <ebb9@byu.net>
1648 * doc/autoconf.texi (Programming in M4sh): Document that
1649 AS_MKDIR_P exits the script on failure.
1650 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1652 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1654 * config/elisp-comp, config/install-sh, config/mdate-sh,
1655 config/missing, config/mkinstalldirs: Sync from Automake.
1657 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
1658 from Automake.
1660 * doc/make-stds.texi: Sync from gnulib.
1662 2006-04-06 Eric Blake <ebb9@byu.net>
1664 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1665 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1666 2006-04-01.
1668 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
1669 Eric Blake <ebb9@byu.net>,
1670 Paul Eggert <eggert@cs.ucla.edu>,
1671 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1673 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1674 whether `set' quotes correctly: redirect stderr of the tested
1675 `set', and use a subshell, for Ultrix; use `sed' instead of
1676 `grep' for zsh `set' which may write binary output; match only
1677 at the beginning of a line, to avoid false positives.
1678 In order to avoid false positives by unrelated variables with
1679 multiline content, put the dump algorithm in a subshell and
1680 unset all variables containing newlines (except some which are
1681 special to the shell). Warn about cache variables that are
1682 unset.
1684 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1686 * config/config.guess, config/config.sub, config/texinfo.tex:
1687 Sync from upstream.
1689 * tests/mktests.sh: Reword comments.
1691 * tests/mktests.sh: Only skip internal macros starting with
1692 `_AC_' or `__AC_'. Noted by Stepan Kasal.
1693 Update exclusion lists for the test suite to this end:
1694 (AC_ARG_VAR): Do test this now.
1695 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1696 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1697 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1698 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1700 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1701 shell issue with double-quoted command substitutions of native
1702 commands.
1703 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
1704 Marshall.
1706 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
1707 no file matches the glob, discard the warning, set `nullglob'.
1708 (syntax-check): Likewise.
1709 (sc_cast_of_x_alloc_return_value): Likewise.
1710 (sc_cast_of_alloca_return_value, sc_error_exit_success)
1711 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
1712 (m4-check): Likewise.
1713 (sc_system_h_headers): Do not print rule on execution.
1714 (sc_tight_scope): Do not fail for non-existing `src' directory.
1715 (sc_changelog): Skip the Copyright footer.
1716 * lib/autoconf/lang.m4: Remove trailing space.
1718 * lib/autoconf/status.m4: More replacements to
1719 <tab><space> where this makes sense.
1721 2006-04-06 Stepan Kasal <kasal@ucw.cz>
1723 * tests/Makefile.am (maintainer-check-posix):
1724 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1726 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1727 ac_config_<foo>s again, sometimes normalized, sometimes not.
1728 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1729 (AC_CONFIG_COMMANDS): Do not do so here.
1730 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1731 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1732 2005-07-25 rewrite. Noticed by Noah Misch.
1734 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1735 _AC_PRESERVE_HELP_ORDER, ...
1736 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1738 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1739 inside m4_expand_once; it is redundant.
1741 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1742 for --help from Cygnus `configure.'
1744 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
1746 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
1747 on a patch proposed by Ralf Wildenhues.
1749 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1751 * lib/autoconf/status.m4: Replace <space>''<tab> with
1752 <tab><space> where this makes sense.
1754 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
1755 Noah Misch <noah@cs.caltech.edu>
1757 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1758 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1759 * doc/autoconf.texi (Help Formatting): New node.
1760 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1762 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1764 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1765 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1766 lib/autoconf/types.m4, lib/autotest/general.m4,
1767 tests/mktests.sh, tests/torture.at: White space cleanup:
1768 remove some SPACE before TAB, or add quoting ('' or @&t@).
1770 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1772 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1774 2006-04-05 Eric Blake <ebb9@byu.net>
1776 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1777 empty test suite works.
1778 * tests/autotest.at (Empty test suite): Remove xfail.
1780 2006-04-05 Noah Misch <noah@cs.caltech.edu>
1782 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
1783 TAGS to ac_config_<foo>s.
1784 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1785 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1786 normalizing it, consistent it with previous releases.
1787 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1789 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1791 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1792 Use simplified args that Eric Blake originally suggested.
1794 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1796 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1797 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1798 Use 'comm' rather than N instances of grep; this also fixes a bug
1799 whereby substrings were incorrectly matched, causing us to not
1800 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.

1893 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1894 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1895 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

1977 m4sugar macros (e.g., m4_define) were expanded after the first
1978 automatic update (e.g., after AC_PREREQ or AC_INIT).

2234 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
2235 newline for portability.
2236 * tests/torture.at (Torturing config.status): Also test 100

2730 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2732 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2733 calls, so that the final expansion of this macro is shorter.
2734 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2735 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2736 the cleanup there. Use AS_VAR_* macros, to be more general.
2737 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2739 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2741 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

2759 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2761 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting

2763 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2764 "if $undefined_var;" succeeds with my shell.
2766 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2767 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2768 but change the m4_divert_text to m4_divert_once.
2770 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2772 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2773 Work around bug in Solaris /usr/xpg4/bin/awk.
2774 The bug is present in at least Solaris 8 through 10.
2776 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2778 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2779 some evil values and relying on the fact that $* concatenates the
2780 parameters by the first character from IFS.
2782 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2783 Stepan Kasal <kasal@ucw.cz>

2786 first header appears, define AH_HEADER.
2787 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2788 Update limitations about when to call AC_CONFIG_HEADERS.
2789 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2790 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2791 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2792 ``Configuration Actions''; fix their index entries.
2794 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2795 options correctly. Process N-M as M-N if M is smaller than N.
2796 Process ranges correctly so that N-N will run only N.
2797 Sort and uniquify the tests that will be run. If there is more
2798 than one test, reinsert the banners for the tests.

2804 before passing the macro name to AH_TEMPLATE.
2806 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status

2827 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2829 When building in place, set srcdir="."; suggested by Tim Van Holder.
2831 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2832 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2833 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2834 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

2851 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2853 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2854 was pushdef'ed twice while popped only once. Push it only once.
2855 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2857 2005-07-26 Stepan Kasal <kasal@ucw.cz>

2866 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2867 "<tab>" in comment, so that the point is understandable.
2869 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2871 Rewrite substantial part of lib/autoconf/status.m4.
2872 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2873 and CONFIG_COMMANDS are not processed in four separate loops.
2874 Instead, there is one main loop. This alows that the common code
2875 is expanded only once, thus config.status (and configure) is smaller.
2877 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2878 the AC_LIST_FILES and cousins macros are no longer used.
2880 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2881 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2882 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2883 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2884 contain the initialization, nor the for loop, nor the associated
2885 commands; all these go to ...
2886 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2887 _AC_OUTPUT_CONFIG_STATUS.
2888 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2889 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2890 (_AC_OUTPUT_FILE): The creation of the sed script ...
2891 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2892 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2893 _AC_OUTPUT_MAIN_LOOP.
2894 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2895 _AC_CONFIG_COMMANDS): Use ...
2896 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2897 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2898 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2899 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2900 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2901 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2902 ... new macros.
2903 (_AC_CONFIG_UNIQUE): Update.
2904 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2905 Replaced by this ...
2906 (_AC_LIST_TAGS): ... new common macro.
2907 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2908 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2909 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2910 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2911 this didn't belong to the `config commands' section.
2912 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2913 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2914 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2915 to the `config commands' section either.
2916 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2917 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2919 ... and many changes to the comments nearby.
2921 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2922 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2923 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2924 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2925 (#define header templates): The comment at the top of the generated
2926 header now includes the name(s) of the source file(s).
2928 Several unrelated small changes:
2930 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2931 parameter to AC_DIAGNOSE.
2932 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2933 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2934 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2935 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2936 with AU::AC_OUTPUT.
2937 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2938 in AC_OUTPUT doesn't double-quote it either.
2939 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2940 parameters.
2942 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2944 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2945 versions of Portland Group compiler produce single- and double-quoted
2946 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2947 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2949 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2951 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2952 This is a corrected version of yesterday's patch.
2954 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2956 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2957 path, too; insert a "===" to emphasize the line.
2959 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2960 ac_cv_build_alias to ac_build_alias.
2961 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2963 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2964 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2965 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2966 (AC_ARG_VAR): ... here.
2967 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2968 target_alias.
2970 Keep a list of all precious variables and process them with one simple
2971 for loop, instead of expanding all commands, or, OTOH, complicated
2972 processing of output of "set".
2973 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2974 variable names in new macro...
2975 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2976 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2977 a loop to assign all ac_env_* and ac_cv_env_* variables.
2978 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2979 to INIT_PREPARE.
2980 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2981 its value to shell variable ac_precious_vars and call
2982 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2983 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2984 _AC_ARG_VAR_VALIDATE.
2986 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2987 and the AC_SUBSTs ...
2988 (AC_INIT): ... here.
2990 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2991 the ac_subst_files section in config.log.
2993 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

3007 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3009 Fix my changes from 2005-07-01; reported by Noah Misch.
3010 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
3011 description, the macro now accepts only a single tag.

3014 Fix cases when the varsions of Autoconf and Autotest don't match.
3015 Reported by Noah Misch.
3016 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
3017 at_top_builddir, for compatibility with older autotest.
3018 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3019 is not set, use at_top_builddir, for compatibility with older
3020 versions of autoconf.
3022 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3024 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3025 Problem reported by Patrick Welche.
3027 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3029 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3030 sed substitution command, so that we allow | in program prefixes
3031 and program suffixes. (& is a problem anyway; we're not fixing
3032 that here.)
3033 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3034 configure_input, top_builddir, srcdir, etc.
3035 * lib/autotest/general.m4 (AT_INIT): Likewise, for

3041 for loop over config.site files using `set', to allow
3042 directory names containing IFS characters.
3044 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
3046 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
3047 directories with weird names. Apparently some people like living
3048 on the edge. However, improve the test that "pwd" actually does
3049 report a name for the working directory.
3050 * NEWS: Remove the claim that we test for funny chars in dir names.
3052 2005-07-01 Stepan Kasal <kasal@ucw.cz>

3068 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
3069 document to output the default config_* lists to config.status.
3070 Don't recognize option --file, if the functionality is not there.
3071 Likewise for --header; moreover, recognize --he and --h as shortcuts
3072 for --help in that case.
3074 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3075 matches the order of execution. No code changed.

3096 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
3097 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3098 (AC_SUBST): Call it.
3099 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3100 the directory specific variables; but don't call it for configure_input.
3102 2005-06-28 Derek Price <derek@ximbiot.com>
3104 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3105 addition.
3107 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3109 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3110 directory have inherent problems with special characters like spaces,
3111 due to limitations in Make syntax. Problem reported by Alexandre
3112 Duret-Lutz.
3113 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

3126 from Justace Clutter.
3127 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
3128 variable into diagnostic. Make the diagnostic an error, not a warning,
3129 because we really don't support spaces and suchlike in dir names.
3130 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3131 Don't worry about backslashes in srcdir; it can't happen now.

3133 Simplify ac_optarg handling.
3134 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

3142 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3144 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3145 that '\|' is not allowed in BREs; recommend using newline separated
3146 list of patterns instead of multiple -e options.
3148 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
3150 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

3158 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3159 b, t, r, w commands require single space, while : cannot have any.
3160 (Special Shell Variables): Fix sed code this in the example.
3161 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3162 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3164 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3165 expand to the empty list. Don't use two pairs of m4_changequote,
3166 it's not necessary.
3168 2005-06-20 Derek Price <derek@ximbiot.com>
3170 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
3172 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
3174 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3175 * doc/autoconf.texi:
3176 Don't mention Solaris versions so much, if a
3177 problem is common to all extant versions of Solaris. Say "SunOS
3178 4" instead of "SunOS" for SunOS 4.
3179 (awk): Mention more of the limitations of traditional Awk.
3180 (cat): Don't talk about cat -v.
3182 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
3184 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
3185 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
3186 but the implementation is entirely different and is designed
3187 to be compatible with glibc strverscmp.
3188 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
3190 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3191 on Mac OS X 10.4 reported by Peter O'Gorman in:
3192 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
3193 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
3194 Use shell builtins rather than 'expr', to work around expr bug.
3196 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3198 * doc/autoconf.texi: "filesystem" -> "file system".
3199 "behaviour" -> "behavior".
3200 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
3201 * lib/autoconf/general.m4: Omit blank after ":" sed command,
3202 as per POSIX.
3203 * lib/m4sugar/m4sh.m4: Likewise.
3204 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
3205 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
3207 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
3208 (.x.1): Ignore the time stamp in the .TH line when deciding whether
3209 to update the man page. That way, we don't have to check in new
3210 man pages every month.
3212 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
3213 quotes and backslashes. Patch from Derek Price.

3220 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
3222 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3223 -u, since it outputs chatter if the input files are the same.
3224 Problem reported by Ralf Menzel.
3226 2005-06-08 Derek Price <derek@ximbiot.com>
3228 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3229 renaming them since they are about to be redefined anyhow.
3231 2005-06-08 Derek Price <derek@ximbiot.com>
3233 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3234 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3235 Move m4_undefine to alphabetical order.
3237 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3239 * README: Recommend GNU M4 1.4.3 or later.
3240 * doc/autoconf.texi (Introduction): Likewise.
3241 Reword to avoid some formatting glitches.
3242 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3243 Clarify explanation of HP compiler bug.
3244 Redo example output tp match current CVS snapshot.
3245 Use @example.org in email addresses when the examples
3246 might get inadvertently cut-and-pasted into user code.
3247 Remove example of autom4te usage that doesn't seem to work now.
3248 Use modern AC_INIT (except when the example is meant to be
3249 shown with Autoconf 2.13).
3250 Update ksh info for Solaris 9 and later.
3251 KB -> kB.
3252 Modernize description of Automake versions a bit.
3253 Don't claim a future version of Autoconf is near.
3254 * doc/install.texi: Reword to avoid some formatting glitches.
3256 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3258 * doc/autoconf.texi: Add [] to examples, so that the manual
3259 follows its own advice about quoting better.
3260 Reword to avoid some formatting glitches.
3261 * doc/installt.exi: Reword to avoid some formatting glitches.
3263 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3264 Tru64 ksh pattern matching bug. Reported against Libtool by
3265 Albert Chin <libtool@mlists.thewrittenword.com> and
3266 Nicolas Joly <njoly@pasteur.fr>.
3268 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3270 m4_cdr of one-member list was [[]] (one-member list containing an
3271 empty string) instead of [] (an empty list. Callers were skewed to
3272 match this misbehaviour. As a consequence of this:
3273 - m4_foreach([x], [], [foo]) expanded to `foo', while
3274 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3275 This bug has been fixed:
3277 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3278 expand to an empty string; print error msg if called without
3279 an argument list.
3280 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3281 misbehaviour; handle [] and [[]] correctly.
3283 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3285 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
3286 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
3287 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
3289 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3291 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3292 swallow records with more than 99 fields.
3293 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3294 parse the long line.
3296 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3298 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3299 swallow literals longer than 399. Reported by Ralf Wildenhues.
3300 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
3301 to workaround this limitation.
3303 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3305 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3306 to gfortran, and make these the first two compiler names
3307 checked (following the general autoconf preference for gcc).
3309 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3311 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3312 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3313 (testsuite): Make sure autotest.m4f is up-to-date before using it.
3315 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
3317 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3318 expression of unbounded size when processing the --list
3319 option. This runs afoul of a limit of 399 bytes per regular
3320 expression on AIX. Problem reported by Ralf Wildenhues.
3322 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
3324 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
3325 * doc/autoconf.texi (Particular Headers): Reword example
3326 for multiline stdbool replacement.
3327 (Setting Output Variables): Reword text a bit. Don't
3328 give all the details about |#_!!_#|.
3329 Reword description of line replacement.
3331 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3333 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3334 now contain newlines, and substituted files must be referenced on
3335 a line alone; the sed scripts to substitute them are now very
3336 different.
3337 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3338 commands can be put in a sed script portably.
3339 * doc/autoconf.texi (Setting Output Variables): Document above
3340 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3341 use of multiline substitution.

3351 * tests/local.at: Don't attempt to check for negated character
3352 classes in shell scripts. The test was too brittle.
3354 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3356 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3357 * doc/autoconf.texi (Limitations of Builtins): Document this
3358 limitation.
3360 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3362 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3363 common code; used in many places in the tree.
3364 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
3365 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
3367 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
3369 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
3370 messages when ac_unique_file is not found.
3371 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3372 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3373 commands, for consistency with AC_MSG_ERROR and such.
3375 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3377 * bin/Makefile.am: Merge the two rules for creating scripts.
3379 2005-05-23 Stepan Kasal <kasal@ucw.cz>
3381 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
3382 obsolete; it was never documented.
3383 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
3385 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3387 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3388 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3389 (ac_top_builddir): ... this ...
3390 (ac_top_build_prefix): ... to this; the old name is also kept, for
3391 backward compatibility.
3392 (ac_top_builddir_sub): New variable, without the trailing slash,
3393 always nonempty.
3394 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3395 * doc/autoconf.texi (Configuration Actions): Rename
3396 ac_top_builddir to ac_top_build_prefix.
3397 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
3398 at_top_builddir to at_top_build_prefix.

3401 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3403 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
3404 of confdefs.h .
3406 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3408 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3409 argument to m4_foreach. I guess it was necessary in the past,
3410 but I think it's a no-op now.
3412 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3414 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3415 ``cat <<_ACEOF'' commands to one.
3416 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3417 * lib/autoconf/status.m4: On various places, use expr instead of
3418 ``echo|sed.''
3419 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3420 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3421 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3422 a range.
3423 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3424 the wrong patterns between ``case'' and ``esac.'' The previous
3425 code had false positives.
3427 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3429 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3430 as on 2005-05-02.
3431 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3432 Mention LIBOBJDIR.

3493 * doc/autoconf.texi (Autoconf Language): Be more precise about
3494 quoting rules. Problems noted by Stepan Kasal.
3495 Also, throughout this document, be more careful about white space.
3496 "blank", "white space", and "space" all have different meanings
3497 and we should be careful to say what we mean.
3499 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3501 Fix C++ related problems reported by Werner Lemberg.
3502 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

3534 not newline.
3536 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3537 by AC_DEFINE; it was a mistake.
3538 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.

3548 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3549 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3550 comment and reduce m4_default([foo], []) to [foo].
3551 (m4_strip): Update the explanation.
3553 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3555 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3556 Remove core.conftest.* too; it's generated by Tru64 5.1.
3557 Problem reported by Jennis Pruett.
3558 * lib/autoconf/functions.m4
3559 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3560 Don't bother to remove core files; AC_RUN_IFELSE should do that
3561 for you.
3563 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3565 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

3611 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3613 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3615 * NEWS: The configure command now warns you if you attempt to use
3616 a directory whose name contains a special character like space,
3617 newline, or "\".
3618 * doc/autoconf.texi (Installation Directory Variables): Allow
3619 "," in file names. Do not use \@; it's not a portable regexp.

3628 unportable file names.
3629 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3630 (AC_INIT): Use it.
3631 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3632 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3633 ac_pwd, and quote srcdir.
3634 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3636 * doc/autoconf.texi: Fix some systematic formatting problems.
3637 ".)" needs a following @: if not at the end of a sentence, and
3638 similarly for "!)". "etc." should be preceded by a comma.
3639 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3641 2005-03-22 Bruno Haible <bruno@clisp.org>
3643 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3644 argument is often called 'build-aux'.
3646 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3648 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3649 macro AC_TRY_LINK is obsolete.
3650 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3651 `AC_CONFIG_FILES'.
3653 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3655 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3656 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3657 from a Common Lisp's `cl'.
3658 (AC_PROG_CXX): Behave according to the documentation: don't
3659 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3660 make the variable CCC precious; use `cl.exe', not `cl'.
3662 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3663 Alexandre Duret-Lutz <adl@gnu.org>
3665 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3666 /dev/null, as "configure" shouldn't read stdin, and this insulates
3667 us from problems (e.g., when testing for "cl"). Also, do this
3668 redirection before invoking "hostname" or "uname", and keep the
3669 original input stream available via...
3670 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3671 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3672 bother with "</dev/null" since it's now done at the top of
3673 'configure'.
3674 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3675 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

3681 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3683 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3684 newline if neither \c nor -n work, as that would output two
3685 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3687 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3689 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3690 This causes that any required macros inside will get before the if.
3691 * doc/autoconf.texi (autom4te.cache): A typo.
3693 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3695 Undo previous change, except keep the change to
3696 lib/autoconf/programs.m4 that replaced grep with shell
3697 pattern-matching. This is because net-snmp configure reads stdin.
3698 Reported by Noah Misch.
3700 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3702 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3703 from /dev/null, as "configure" shouldn't read stdin, and this
3704 insulates us from problems (e.g., when testing for "cl").
3705 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3706 before invoking "hostname" or "uname".
3707 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3708 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3709 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3710 "</dev/null" since it's now done at the top of 'configure'.
3711 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3712 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3713 Also, replace grep with shell pattern-matching, to save a process.
3715 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3717 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3718 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3719 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3720 compiler.
3722 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3724 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3725 grep -q isn't portable. Improve grep -s explanation.
3726 Problem reported by Dan Manthey.
3728 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3730 * doc/autoconf.texi (Special Shell Variables): Clarify
3731 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3733 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3735 * doc/autoconf.texi: Use @acronym for DJGPP.
3736 Fix some @code's that should have been @env's, and vice versa.
3737 Sort environment variable names.
3738 Mention that shells no longer inherit IFS.
3739 Don't recommend PATH_SEPARATOR=';' so strongly.
3740 Mention that $RANDOM might expand to the empty string.
3741 "symlink" and "soft link" -> "symbolic link".
3742 Improve mktemp description (reported by Bruno Haible).
3744 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3746 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3747 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3748 Likewise.

3754 * NEWS: Mention AT_COPYRIGHT.
3756 * tests/local.at (AT_CMP): Use diff directly on input files rather
3757 than copying them.
3759 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3760 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3762 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3763 and Paul Eggert <eggert@cs.ucla.edu>

3772 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3773 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3774 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

3776 (Standard regular expressions): New test.
3777 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3778 excess test name quoting.
3779 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3780 CPPFLAGS to `configure' instead of setting it in `configure'.
3782 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3783 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3784 on some platforms.
3786 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3787 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

3790 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

3795 * tests/c.at (Extensions): Do not exit early.

3815 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3817 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3818 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3820 Try not to generated lines of unlimited length, as POSIX places a
3821 2047-byte limit on line length of portable text files.
3822 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3823 Use newline as a separator, not space.
3824 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
3825 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
3826 space.
3828 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3830 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
3831 as_func_*. Add test to check whether positional parameters
3832 are restored after function return.
3834 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
3836 * doc/autoconf.texi (Special Shell Variables): Mention _,
3837 BIN_SH, DUALCASE. Say that variables other than "status" are safe
3838 if they contain a lower-case letter. The DUALCASE problem was
3839 reported by Ralf Wildenhues.
3841 * bin/autoconf.as: Don't exit with status 0 after write failure
3842 with --help or --version.

3849 Unicos 9 sed limitations.
3850 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

3854 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
3856 * man/Makefile.am (.x.1): Go back to the simple solution, but take
3857 care to echo the commands, so the user knows what's going on.
3858 Modified from a suggestion by Stepan Kasal.
3860 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

3868 Based on a proposed patch by Ralf Wildenhues.
3870 * man/Makefile.am (.x.1): Make sure the required generated files
3871 are up to date. Problem and original solution proposed by Stepan Kasal.

3879 2005-01-29 Stepan Kasal <kasal@ucw.cz>
3881 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3882 Update the long comment explaining it.
3884 m4_require no longer writes an ``is required by'' line to the
3885 execution stack. It contains only one bit of non-redundant
3886 information: that the macro was required, not called. And even
3887 this bit is useless in most situations: have you ever met a macro
3888 which both calls and requires the same macro?
3890 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3891 (_m4_defun_pro_outer): ... only via this macro, for the outermost
3892 macro.
3893 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
3894 (m4_expansion_stack_pop): Remove the misplaced comment.
3895 (m4_require): Don't put the ``is required by'' line to the
3896 execution stack; slightly improve the out-of-a-defun error message.
3897 (_m4_divert_grow): New macro, counter for the temporary diversions.
3898 (_m4_require_call): Use it.
3899 * tests/m4sugar.at (m4_require): Expect output without the
3900 ``is required by'' messages.
3902 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3904 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3905 rather than x for expr.
3907 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3908 this is safe.
3909 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
3910 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

3920 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
3921 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
3922 from masters, so that FileUtils.pm's update_file provide --force
3923 support.
3924 * bin/autoheader.in: Pass $force to update_file so that
3925 config.h.in is always recreated when --force.
3927 2005-01-24 Stepan Kasal <kasal@ucw.cz>
3929 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
3931 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3933 * doc/autoconf.texi (Limitations of Builtins): Clarify that
3934 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
3936 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3938 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3939 Warn about newline stripping in `` and $(). Update Solaris
3940 version to 9.
3941 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3942 X insulates us from future changes to Posix.
3943 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3944 stripping.
3946 2005-01-19 Stepan Kasal <kasal@ucw.cz>
3948 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

3951 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
3953 * doc/autoconf.texi (Limitations of Usual Tools): Document bug

3964 ulongval to be static, to avoid unwanted GCC warning. Problem
3965 reported by Michael Jennings via Daniel Reed; see
3966 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
3968 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3970 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3972 datadir, infodir, and mandir. Adjust argument parsing code.
3973 (_AC_INIT_HELP): Update help text.

3975 new variables.
3977 2005-01-04 Noah Misch <noah@cs.caltech.edu>
3979 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
3980 not seem to work, assume it does set $(MAKE).
3981 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
3983 2005-01-03 Stepan Kasal <kasal@ucw.cz>
3985 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

3991 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
3992 (_m4_divert_n_stack): New macro; the expansion is
3993 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
3994 otherwise.
3995 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3996 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3997 stored in _m4_divert_diversion or _m4_divert_dump.
3998 (m4_divert_pop): When the parameter is given, compare the symbolic
3999 name with the last diversion pushed on the stack. Previously, the
4000 current diversion was compared with the numeric value of the
4001 diversion given as the parameter.
4002 (m4_require): If the macro hasn't been expanded yet, call ...
4003 (_m4_require_call): this new macro.
4005 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4036 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
4037 signals that the package uses Automake; a `Makefile.am' is typical but
4038 not essential. Reported by Magnus Therning.
4039 * tests/torture.at (autoreconf.): New banner.
4040 (autoreconf and non-AC configure): Rename to `Non-Autoconf
4041 AC_CONFIG_SUBDIRS'.

4310 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4311 "char c = '\200';" rather than "char c = 0x80;" as the

4313 overflow on signed char hosts.
4315 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4316 to -qlanglvl=ansi. We don't want to disable extensions.

4429 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4430 "/usr/include", clear ac_x_includes instead of leaving it as "no"

4525 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4526 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4527 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4529 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4531 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4532 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4533 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4534 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4535 * lib/autom4te.in (Automake-preselections): Preselect
4536 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4538 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4540 * lib/autom4te.in (Automake-preselections): Preselect
4541 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4542 trace them.
4544 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4546 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4547 Tru64.
4548 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4549 Document problem with "`""`" in pdksh POSIX mode.
4551 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4553 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4554 with pdksh, too. Problem reported by Patrick Welche via
4555 Gary V. Vaughan.
4556 * doc/autoconf.texi (Shellology): Note that set -o posix is
4557 useful for pkdsh, too.
4559 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4561 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4562 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4563 Don't fail if ENV or BASH_ENV is readonly.
4564 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4565 etc. are read only. Problem reported by Ludovic Courtes.
4567 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4569 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4570 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4571 (trivial change)
4573 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4575 * doc/autoconf.texi (File System Conventions): Warn about
4576 names like "aux". Problem reported by Eric Blake.
4578 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4579 by zero instead of array size, so that we can use any arithmetic
4580 constant expression (instead of requiring an integer constant
4581 expression). This allows us to test expressions like DBL_MAX <
4582 LDBL_MAX, which didn't conform to the C standard using the old
4583 method.
4584 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4585 now that we can do floating-point tests at compile time.
4587 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4589 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4590 and LDBL_EPSILON, as the resulting expression isn't an
4591 integer constant expression and violates the C standard.
4592 Problem reported by Nelson H. F. Beebe. Also, check
4593 for "L" suffix, and check that long double doesn't have
4594 worse range or precision than double, that mixed-mode
4595 arithmetic doesn't generate a diagnostic, that double
4596 constants fit in long double.
4598 2004-06-03 Kevin Ryde <user42@zip.com.au>
4600 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4601 malloc(0) and realloc(NULL,size).
4603 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4604 Bob Proulx.
4606 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4608 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4609 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4610 by Jim Meyering.
4612 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4614 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4615 can be rewritten using if-then-else. Suggested by Bruno Haible.
4617 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4619 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4620 Problem reported by Stepan Kasal.
4622 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4624 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4625 change). Patch reported by Ralf Wildenhues in
4626 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4628 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4629 function F exists if the compiler and linker let you compile an
4630 expression like (F != 0). Recent versions of GCC optimize away
4631 the reference to F in that case, since every function address must
4632 be nonzero, so the link succeeds even if F does not exist.
4633 Problem reported by Manu in
4634 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4636 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4637 "Unix". Many uses changed.
4638 (Limitations of Builtins): Explain better why the ! command isn't
4639 portable.
4641 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4643 * lib/autom4te.in (Automake-preselections): Preselect
4644 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4646 2004-05-19 Kevin Ryde <user42@zip.com.au>
4648 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4649 referencing AC_FUNC_STRERROR_R.
4651 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4652 note pessimistic assumption when cross compiling.
4654 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4656 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4657 (until 2004) invoked subcommands with sh -e, contra POSIX.
4658 Reported by Kevin Ryde.
4660 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4662 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4663 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4664 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4665 `test -f " /usr/bin/grep"', which _always_ failed.
4666 (AC_PROG_SED): Ditto bogus PATH fix.
4667 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4668 requires that grep correctly supports _multiple_ `-e' options, rather
4669 than stating only that grep should accept `-e'.
4671 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4673 Port to C99, which requires that 'exit' be declared.
4675 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4676 to ensure that stdlib.h is included.
4677 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4678 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4679 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4680 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4681 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4682 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4683 when using 'exit' in a test; C99 requires that 'exit' be declared.
4685 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4687 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4688 now prefers 'grep' implementations that accept -e.
4689 (Limitations of Usual Tools): Describe problems of traditional
4690 egrep and fgrep with long input lines, and of traditional grep
4691 with -e.
4692 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4693 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4694 All callers changed. Append /usr/xpg4/bin to the PATH, for
4695 Solaris.
4696 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4697 the user with complaints about multiple -e options.
4698 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4699 Define it with AC_PROG_GREP.
4700 * configure.ac (AC_PROG_GREP): Add.
4701 * lib/freeze.mk (GREP): New macro.
4703 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4705 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4706 a possible candidate only after all others fail, rather than
4707 consulting it first. This improves backward compatibility by
4708 better reflecting the way shell selection occurred in previous
4709 versions of Autoconf, and should help to avoid triggering latent
4710 problems in other packages, such as the one in Automake where zsh
4711 is not handled robustly:
4712 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4713 Although it is not Autoconf's responsibility to work around
4714 problems in Automake, it nevertheless makes sense to avoid
4715 introducing unnecessary incompatibilites.
4717 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4718 Gary V. Vaughan <gary@gnu.org>
4720 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4721 how deeply nested we are when a suitable tool is found, set the
4722 ac_path_TOOL_found flag.
4723 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4724 nested we are in this macro. Break out of all 3 nested loops if
4725 ac_path_TOOL_found is set.
4727 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4729 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4730 of the _AS_PATH_WALK loop too if GNU flavor is found.
4732 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4734 * doc/autoconf.texi (Limitations of Make): Update documentation
4735 for `$<'. New entry `Long lines', based on a report from Simon
4736 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4737 paragraph about DJGPP, based on a mail from Richard Dawe.
4739 2004-04-20 Paul Eggert <eggert@twinsun.com>
4741 * tests/c.at (C keywords): Don't assume that GCC supports
4742 "restrict" and "inline", as sufficiently-old GCC versions do not
4743 (also, GCC configured to be in pedantic C89 mode does not).
4744 Problem reported by Sumit Pandya in:
4745 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4747 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4748 consider -g to work if it generates warnings when plain compiles
4749 don't. Problem reported by Braden McDaniel in:
4750 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4752 * doc/autoconf.texi (Slashes): New section, to document a problem
4753 reported by Jim Meyering in:
4754 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4756 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4757 linker output files before linking, to work around IRIX 6 linker bug.
4758 Problem reported by Rainer Orth in:
4759 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4761 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4763 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4764 best tool so far counter rely on the tool path variable name to
4765 avoid checks for one tool being affected by the results of running
4766 the length check on a previous tool.
4768 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4769 match expression argument, as different greps have different
4770 regular expression flavours.
4771 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4772 literals.
4773 (AC_PROG_EGREP): Pass 'EGREP$'.
4774 (AC_PROG_GREP): Pass 'GREP$'.
4776 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4778 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4779 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4781 2004-03-29 Paul Eggert <eggert@twinsun.com>
4783 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4784 Types, Specific Compiler Characteristics, System Services,
4785 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4786 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4787 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4788 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4789 Likewise.
4790 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4791 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4792 AC_TYPE_OFF_T): Likewise.
4793 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4794 Likewise.
4796 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
4797 pacify libtool 1.5.2. Fix quoting problems in sed command.
4799 2004-03-28 Paul Eggert <eggert@twinsun.com>
4801 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4802 now defines HAVE_DECL_TZNAME if it is declared, when
4803 HAVE_STRUCT_TM_TM_ZONE is not defined.
4804 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4805 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4806 for HAVE_TZNAME.
4808 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4810 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4811 superfluous backslashing of quotes (") in sed expressions;
4812 thanks to Paul Eggert.
4814 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4816 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4817 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4818 H. F. Beebe for the bug report.
4820 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4822 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4823 quoted -cmdline argument in Portland Group compiler (bug
4824 reported by Jeffrey J. Barteet).
4826 2004-03-25 Kevin Ryde <user42@zip.com.au>
4828 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4829 (Run Time): ... here, where it's now mentioned.
4831 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
4833 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4834 inherits from language Autoconf-without-aclocal-m4.
4835 (Customizing autom4te): Adjust example; the cache must now be
4836 disabled for language Autoconf-without-aclocal-m4.
4838 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
4839 Nathanael Nerode <neroden@twcny.rr.com>

4849 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
4850 AC_CHECK_TOOLS.
4851 (Specifying Names): Document the reason for these future
4852 behavioral changes.
4853 * tests/mktests.sh: Do not generate tests for the
4854 new macros.
4855 * NEWS: Document these changes.
4857 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4858 they make TeX hang up.
4860 2004-03-15 Paul Eggert <eggert@bogus.example.com>
4862 * NEWS: New macro AC_CHECK_ALIGNOF.
4863 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4864 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4865 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4866 vowel.
4867 (AC_CHECK_ALIGNOF): New macro.
4868 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
4869 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
4870 those for sizeof.
4872 2004-03-03 Paul Eggert <eggert@twinsun.com>
4874 * bin/Makefile.am (edit): Don't use $< in a context where
4875 POSIX doesn't require support for it. Use $@.in instead.
4876 Problem reported by Anthony N. Frasso in
4877 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4878 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4880 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4882 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4883 from the next generation of Libtool.
4884 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4886 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4888 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

4891 2004-02-18 Paul Eggert <eggert@twinsun.com>
4893 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4894 problem on QNX reported by Stephen Rasku in
4895 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4897 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4898 $(m4sh_m4f_dependencies); this removes a FIXME.
4899 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4900 (MAINTAINERCLEANFILES): Split into pieces,
4901 one per related section. Add $(srcdir)/wrapper.in.
4903 2004-02-09 Paul Eggert <eggert@twinsun.com>
4905 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4906 AC_SUBST provides no portable way to escape literal newlines.
4908 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4909 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4910 Darwin uses -lcrt2.o and there's little point to cataloging all
4911 the system variants. Partial fix reported by Andreas Waechter in:
4912 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4913 for bug reported by Nelson H. F. Beebe in:

4921 acobsolete.m4, suggested by Alexandre Duret-Lutz.
4923 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
4925 * bin/autoupdate.in: Define __file__ so that warnings
4926 refer to the correct file.
4927 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4928 the behavior of the third argument.
4929 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4930 correctly the behavior of the third argument. Document
4931 what the three macros that AU_DEFUN defines do. Fix
4932 warning message when the third argument includes $0
4933 (reported by Alexandre Duret-Lutz).
4935 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4936 Eric Sunshine <sunshine@sunshineco.com>
4937 Paul Eggert <eggert@twinsun.com>
4939 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4940 (AS_INIT): Output shell initialization there. Removed optional
4941 parameter. Expand _AS_SHELL_FN_SPY.
4942 (AS_INIT_WITH_SHELL_FN): Removed.
4943 (_AS_SHELL_FN_SPY): New macro.
4944 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4945 macros.
4946 (AS_SHELL_SANITIZE): Remove loop to find better shell
4947 and documentation for the parameter.
4948 (_AS_DETECT_BETTER_SHELL): Move it here.
4949 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
4950 (_AS_RUN): Move it here, support testing with eval.
4951 (AS_REQUIRE_SHELL_FN): Require shell functions when
4952 it is used.
4953 (_AS_LINENO_WORKS): Put around braces, we do not
4954 trigger the bash bug anymore.
4955 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4956 use AS_INIT_WITH_SHELL_FN.
4957 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4959 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4961 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
4962 * doc/autoconf.texi: Don't say that the third parameter
4963 is broken.
4964 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
4965 (AU_DEFUN): Honor the third parameter, create autoupdate
4966 macros with AU_DEFINE.
4967 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,

4976 * lib/autoconf/status.m4: Remove FIXME.

4987 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

4989 the 2003-05-22 change, which removed the older years from the list.
4990 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4992 2004-01-27 Gary V. Vaughan <gary@gnu.org>

4997 possible.
4998 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4999 AC_PROG_GREP.
5000 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5001 egrep and fgrep respectively if $GREP -E/-F don't work.
5002 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5003 _AC_PROG_GREP, and AC_PROG_SED.
5004 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5005 longest input length accepted by a command.
5006 (AC_PROG_SED): Use it.
5007 * doc/autoconf.texi (Particular Programs): Document the changes.

5010 2004-01-27 Paul Eggert <eggert@twinsun.com>
5012 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

5014 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
5015 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
5017 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
5018 bin/autoconf.in, config/Makefile.in, config/config.guess,
5019 config/config.sub, config/install-sh, config/mdate-sh,

5034 2004-01-26 Paul Eggert <eggert@twinsun.com>
5036 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5037 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5038 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5039 not <inttypes.h>. Problem reported by Tim Mooney in
5040 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5041 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5042 Likewise.
5044 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5045 otherwise "make check" fails because it forbids cmp (I guess
5046 because cmp treats files as binary on DOS-like systems).
5048 * tests/mktests.sh: Update copyright date to 2004, since some tests
5049 have changed in 2004.
5051 2004-01-23 Gary V. Vaughan <gary@gnu.org>

5054 non-truncating sed or gsed program in PATH.

5057 * NEWS: Updated.
5059 2004-01-15 Paul Eggert <eggert@twinsun.com>
5061 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5062 -std1 disables some useful extensions on Tru64. Problem reported
5063 by N. Lichtmaier in
5064 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5066 2004-01-14 Paul Eggert <eggert@twinsun.com>
5068 * doc/autoconf.texi (Programming in M4sh): Document that
5069 AS_MKDIR_P succeeds if the destination is a symbolic link
5070 to an existing directory.
5071 (Limitations of Usual Tools): Note that mkdir -p might not
5072 succeed on symlinks to directories.
5074 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5076 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
5077 * bin/autoheader.in: Grammar fix in message.
5078 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
5079 Test for dir before calling mkdir -p. (trivial changes)
5081 2004-01-13 Eric Blake <ebb9@byu.net>
5083 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5084 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5086 2004-01-10 Jim Meyering <jim@meyering.net>
5088 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
5090 2004-01-09 Paul Eggert <eggert@twinsun.com>
5092 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5093 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5094 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5095 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5096 AC_COMPILE_IFELSE, since we now assume our caller invokes
5097 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5098 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5099 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5100 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5102 2004-01-07 Paul Eggert <eggert@twinsun.com>
5104 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5105 `"'...'"`, as it's confusing (and I suspect it may not work on
5106 some platforms). The code was incorrect anyway, as it assumed
5107 that \$ evaluated to itself in that context. Reported by
5108 Alexandre Duret-Lutz.
5110 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
5112 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
5113 and _LT_AC_TAGCONFIG.

5117 * doc/autoconf.texi (One Macro Call): Fix an incorrect
5118 example, and add more examples. Reported by Eric Sunshine.
5120 2004-01-05 Paul Eggert <eggert@twinsun.com>
5122 * doc/autoconf.texi (Limitations of Usual Tools):
5123 Remove warning against "rm -fr" introduced yesterday; it
5124 was a false alarm.
5126 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
5127 autoscan, autoupdate, ifnames): Don't use chmod -w.
5128 * lib/Makefile.am (autom4te.cfg): Likewise.
5129 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
5130 "chmod -w".

5133 Paolo Bonzini <bonzini@gnu.org>
5135 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
5136 by doing lineno substitution only on lines containing "$LINENO".
5138 2004-01-04 Paul Eggert <eggert@twinsun.com>
5140 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
5141 Use "rm -f" to remove conftest.sed, not plain "rm".
5142 Bug reported by David Relson in
5143 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
5145 * Makefile.am (autom4te-update):
5146 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
5147 * Makefile.maint (my-distcheck, do-po-update): Likewise.
5148 * doc/autoconf.texi (Guidelines): Likewise.
5149 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

5154 * tests/Makefile.am (clean-local): Likewise.
5155 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
5156 srcdir): Likewise.
5157 * doc/autoconf.texi (Limitations of Usual Tools):
5158 Warn against "rm -fr".
5160 2004-01-03 Paul Eggert <eggert@twinsun.com>
5162 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5163 -c -o might not work. From a suggestion by Kevin Ryde.
5164 (C Compiler, Generating Sources, Limitations
5165 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5166 Don't put '-o' after non-options, as POSIX doesn't allow this.
5167 Mention that cc's name might be gcc or c89 or whatever.
5169 2004-01-04 Kevin Ryde <user42@zip.com.au>
5171 * doc/autoconf.texi: Add various further index entries.
5173 2003-12-29 Paul Eggert <eggert@twinsun.com>
5175 * bin/autoreconf.in (autoreconf_current_directory):
5176 Fix typo: mkdir without umask arg.
5178 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
5180 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
5181 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
5182 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
5183 explanation clearer.
5185 2003-12-24 Andreas Schwab <schwab@suse.de>
5187 * doc/autoconf.texi (Default Includes): Fix misspelling of
5188 AC_INCLUDES_DEFAULT.

5192 * configure.ac: Test if sh -n works.
5193 * configure: Regenerate.
5194 * tests/atlocal.in: Store the result here.
5195 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
5196 tools.at, looking in atlocal's ac_cv_sh_n_works instead
5197 of explicitly testing.
5198 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
5199 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
5200 * tests/tools.at (Syntax of the shell scripts): Simplify
5201 using AT_CHECK_SHELL_SYNTAX.

5215 Extracted from AS_SHELL_SANITIZE.
5216 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
5217 macros.
5218 (AS_SHELL_SANITIZE): Move reinvocation code from
5219 _AS_LINENO_WORKS, use it to find out if shell
5220 functions work.
5221 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
5222 does not work.
5223 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
5224 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

5242 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

5270 parameter of AU_DEFUN.

5285 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
5286 than $target since the latter is not usual, add guidelines on when to

5427 _AC_COMPILER_EXEEXT to attempt a link. If linking fails,
5428 override AC_LINK_IFELSE.
5430 2003-10-15 Paul Eggert <eggert@twinsun.com>
5432 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug in
5433 pdksh 5.2.14. Bug reported by Ralf Corsepius.
5434 * doc/autoconf.texi (Shellology): Mention the Korn shell and pdksh.
5435 Mention /usr/dt/bin/dtksh on Solaris.
5436 (Shell Substitutions): Warn about $((...)).
5437 (Parentheses): New section.
5439 2003-10-15 Kevin Ryde <user42@zip.com.au>
5441 * doc/autoconf.texi (Function Portability): Add @prindex for exit.
5442 Add putenv and unsetenv. Add sysconf _SC_PAGE_SIZE.
5444 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
5446 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5447 cross test.
5449 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5451 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5452 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
5454 2003-10-10 Andreas Schwab <schwab@suse.de>
5456 * bin/autoheader.in: Avoid empty first line in --version and
5457 --help output.
5458 * bin/ifnames.in: Likewise.
5460 2003-10-09 Paul Eggert <eggert@twinsun.com>
5462 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
5463 Issue a more-informative diagnostic.
5464 Problems reported by Eric Sunshine.
5466 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5468 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5469 -mGLOB_options_string stuff for Intel ifc, which can cause
5470 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
5471 pattern-matching instead of grep.
5473 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5475 * doc/autoconf.texi: Document new FC Fortran macros.
5477 2003-10-08 Gary V. Vaughan <gary@gnu.org>
5479 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
5480 that future autopoint/aclocal/automake/autoreconf will be able
5481 to trace to find where to install local m4 macros.
5482 * doc/autoconf.texi (Input): Document it.
5483 * NEWS: Updated.
5485 2003-10-06 Gary V. Vaughan <gary@gnu.org>
5487 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
5488 -lcrtbegin.o to list of ignored flags and fix underquoting of
5489 -lcrt[01].o.
5491 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
5493 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5494 cache variable instead of $G77 to decide whether to include -O2,
5495 since $G77 is specific to Fortran 77.
5497 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5499 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
5500 free" flag. Re-order flags tested into rough order of popularity.
5502 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5504 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5505 arguments so that it can be used with syntax identical to
5506 AC_PROG_F77, and so that we can more easily decide to
5507 remove/deprecate the DIALECT optional argument in the future if it
5508 proves troublesome.
5509 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5510 non-freeform-supporting compilers. Document freeform flags.
5512 2003-10-03 Akim Demaille <akim@epita.fr>
5514 * configure.ac: Look for emacs, not macs.
5515 Reported by Eric Sunshine.
5517 2003-10-03 Akim Demaille <akim@epita.fr>
5519 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5520 * bin/autoreconf.in (autoreconf_current_directory): Create the
5521 AUX_DIR if needed, for sake of automake --add-missing etc.
5522 Suggested by Alexandre Duret-Lutz.
5524 2003-10-03 Akim Demaille <akim@epita.fr>
5526 * configure.ac: Quotation and formatting changes.
5527 (EMACS): Don't set it if it is not recent enough to support
5528 autoconf-mode.el.
5529 From Eric Sunshine.
5531 2003-10-02 Akim Demaille <akim@epita.fr>
5533 * bin/ifnames.in (&scan_file): Skip C++ comments.

5545 2003-09-30 Paul Eggert <eggert@twinsun.com>
5547 * lib/Autom4te/XFile.pm: Use Errno.
5548 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
5549 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
5551 2003-09-30 Akim Demaille <akim@epita.fr>
5553 * config/announce-gen (&print_news_deltas): Extracted from...
5554 (&print_changelog_deltas): here.
5555 (&news_file): Rename as...
5556 (@news_file): this.
5558 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
5560 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
5561 have been created when invoking the compiler.
5562 * tests/fortran.at (GNU Fortran 77): Quote $G77.
5564 2003-09-29 Akim Demaille <akim@epita.fr>
5566 Version 2.57e.

5570 2003-09-28 Paul Eggert <eggert@twinsun.com>
5572 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
5573 Problem reported by Lars J. Aas in
5574 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
5575 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5576 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5577 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5579 2003-09-26 Akim Demaille <akim@epita.fr>
5581 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5582 directory for AC_CONFIG_COMMANDS' first argument exists.
5583 This makes valid the invocation of _AC_SRCPATH that follows.
5584 Reported by Eric Sunshine.
5585 * doc/autoconf.texi (Configuration Commands): Adjust.
5587 2003-09-26 Akim Demaille <akim@epita.fr>
5589 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5590 Reported by Ralf Corsepius.
5592 2003-09-26 Akim Demaille <akim@epita.fr>
5594 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5595 arguments.
5596 Actually, use AU_ALIAS.
5597 From Bruno Haible.
5599 2003-09-26 Paul Eggert <eggert@twinsun.com>
5601 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
5602 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
5603 Problem reported by Eric Sunshine in:
5604 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
5606 2003-09-26 Akim Demaille <akim@epita.fr>
5608 The test suite are sometimes assigning timings incorrectly.
5609 Reported by Henk Krus.
5610 Diagnosed by Nicolas Joly.
5612 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5613 AT_help_all.
5614 Instead of making AT_help a sequence of assignments to grow
5615 $at_help_all, just make AT_help_all be the growing contents of
5616 $at_help_all, and make a single assignment in...
5617 (AT_INIT): here.
5618 (at_times_skip): Flip the meaning and rename as...
5619 (at_times_p): this.
5620 (AT_INIT): When summarizing the test that ran, remove
5621 $at_times_file after use, and check it is present before trying to
5622 use it.
5624 2003-09-25 Akim Demaille <akim@epita.fr>
5626 Version 2.57d.
5628 * bin/Makefile.am (edit): Handle '@configure_input@'.
5629 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5630 (ifnames): chmod -w.
5631 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5632 executables, not bin/ executables! Otherwise all the magic needed
5633 to find non installed files is turned off. This caused a failure
5634 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5635 as found in its environment (sent by tests/autoreconf): pointing
5636 to bin/autom4te that could not find its files.
5637 * tests/mktests.sh: Force the replacement of generated files, for
5638 the sake of "mv" program that are interactive when overwriting a
5639 -w file.
5640 * config/install-sh: Upgrade from CVS Automake.
5642 2003-09-23 Paul Eggert <eggert@twinsun.com>
5644 * doc/autoconf.texi (Limitations of Builtins): Document test -h
5645 versus test -L issues.
5647 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
5648 Paul Eggert <eggert@twinsun.com>
5650 Trivial change to support GCC's configuration procedure.
5651 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5652 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5653 about inconsistency if the preprocessor is set to give errors for
5654 any warning.
5655 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5657 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
5659 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
5660 and XFile.pm from Automake.

5670 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
5671 from masters.
5673 2003-09-12 Akim Demaille <akim@epita.fr>
5675 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5676 not asm/types.h.
5678 2003-09-11 Akim Demaille <akim@epita.fr>
5680 * doc/autoconf.texi (Header Portability): linux/random.h.
5681 From Peter Hendrickson.
5683 2003-09-10 Akim Demaille <akim@epita.fr>
5685 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5686 willing to edit the output files.
5688 2003-09-10 Akim Demaille <akim@epita.fr>
5690 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5691 and AC_FC_FREEFORM.
5692 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5693 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
5695 2003-09-09 Akim Demaille <akim@epita.fr>
5697 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
5698 Reported by Gary Vaughan.

5704 trailing files.
5706 2003-09-07 Paul Eggert <eggert@twinsun.com>
5708 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
5709 Improve the accuracy of the wording about obsolescence.
5710 From a suggestion by Ian Lance Taylor in
5711 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5713 2003-09-05 Paul Eggert <eggert@twinsun.com>
5715 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5716 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5718 2003-09-04 Akim Demaille <akim@epita.fr>
5720 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5721 AC_FUNC_WAIT3.
5723 2003-09-04 Akim Demaille <akim@epita.fr>
5725 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5726 (freeze): When exiting, use $exit_code.
5727 * lib/autoconf/fortran.m4: Comment changes.
5729 2003-09-04 Akim Demaille <akim@epita.fr>
5731 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5733 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5735 Add support for newer Fortran dialects. The F77 interface is
5736 unchanged, and continues to support Fortran 77. New FC macros
5737 correspond to all the old F77 macros, with output variables FC,
5738 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5739 available dialect, but older dialects can be specified. There are
5740 new macros AC_FC_SRCEXT to set the source extension, and
5741 AC_FC_FREEFORM to accept free-form source files.
5743 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5744 New macros.
5745 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
5746 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
5747 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
5748 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

5755 AC_FC_DUMMY_MAIN, _AC_FC_MAIN, AC_FC_MAIN, __AC_FC_NAME_MANGLING,
5756 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
5757 AC_FC_SRCEXT, AC_FC_FREEFORM):
5758 New macros.
5759 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
5760 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
5761 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5762 Rewrite in terms of the above.
5763 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5764 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
5765 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
5766 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
5768 2003-09-02 Paul Eggert <eggert@twinsun.com>
5770 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5771 Document problems with timestamp resolution that 'make', 'cp -p', and
5772 'touch -r' have.
5774 2003-08-27 Akim Demaille <akim@epita.fr>
5776 * tests/m4sugar.at (cross_warning): Make sure to enable the
5777 output, so that we can track spurious m4sugar output.
5778 * tests/local.at: Require 2.57.
5779 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5780 are defaulted by AT_CHECK anyway.
5781 Use AT_CHECK_AUTOM4TE.
5782 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5783 missing dnl.
5785 2003-08-27 Akim Demaille <akim@epita.fr>
5787 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5788 when -Wobsolete is set.
5789 Set it on by default.
5790 Suggested by Klee Dienes.
5792 2003-08-27 Akim Demaille <akim@epita.fr>
5794 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
5795 documentation.
5796 From Guido Draheim.
5798 2003-08-26 Akim Demaille <akim@epita.fr>
5800 * doc/autoconf.texi (Output): Make clear that one can run code
5801 after AC_OUTPUT.
5803 2003-08-25 Akim Demaille <akim@epita.fr>
5805 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
5806 CVS Bison.

5822 2003-08-22 Akim Demaille <akim@epita.fr>
5824 Version 2.57b.
5826 * Makefile.cfg (local-checks-to-skip): New.
5827 * Makefile.maint (local-check): Rename as...
5828 (local-checks-available): this.
5829 (local-check): New.
5831 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
5832 * configure.ac: Require Automake 1.7.6.
5834 2003-08-22 Akim Demaille <akim@epita.fr>
5836 Output stack traces in warnings.
5838 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
5839 Replace the former...
5840 (m4_warn): Pass the call stack to _m4_warn.
5841 * bin/autom4te.in: Adjust to output the call stack.
5842 * tests/m4sugar.at (m4@&t@_warn): Adjust.
5844 2003-08-22 Akim Demaille <akim@epita.fr>
5846 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
5847 * bin/autom4te.in: Adjust.
5849 2003-08-21 Akim Demaille <akim@epita.fr>
5851 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
5852 (&verbose): Remove.
5853 (&getopt): Adjust the note and verb channels, depending upon
5854 --verbose.
5855 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
5856 * bin/autoupdate.in: Adjust.
5857 Use &verb, not &verbose.
5859 2003-08-21 Akim Demaille <akim@epita.fr>
5861 * bin/autoheader.in (&parse_args): Use &parse_warnings and
5862 &parse_WARNINGS.
5863 ($help): Use Autom4te::ChannelDefs::usage.
5864 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5865 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5867 2003-08-21 Akim Demaille <akim@epita.fr>
5869 First stab at preserving warnings between calls to autom4te,
5870 including when the cache is used.
5872 There are still several issues: (i) there are too many runs of m4
5873 (one for include, one for warnings, and some more), (ii) warnings
5874 spreading on several lines are not handled gracefully, (iii) the
5875 code meant to have the call stack display for errors does not work
5876 (its handling should move from m4 to autom4te).
5878 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5879 Use them.
5880 (@preselect): Add m4_warn.
5881 ($exit_status): Remove, use $exit_code.
5882 ($help): Use Autom4te::ChannelDefs::usage.
5883 (&handle_m4): No longer define the m4_warnings.
5884 At each run, extract and report the warnings.
5885 Always cache the result, including if the exit status is on
5886 failure, since if nothing changes, we should result in the same
5887 failure, hence we can use the cache.
5888 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5889 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5890 Remove.
5891 (m4_warn): Redefine as a do-nothing: it is its invocation that
5892 matters, as warnings are now reported via traces.
5893 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5894 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5895 the latter reveals calls to the former.
5897 Adjust the tests.
5899 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

5936 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5937 (&xsystem, &contents): Remove, since they are exported by...
5938 * lib/Autom4te/FileUtils.pm: this.
5939 More perldoc.
5940 * lib/Autom4te/General.pm (&up_to_date_p): Move to...

6002 2003-08-13 Derek Price <derek@ximbiot.com>
6004 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

6021 in Bash 2.01. Problem reported by Brian Gough in
6022 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
6024 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
6026 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
6027 -lcrt1.o, for OS X. (trivial change)
6029 2003-07-07 Paul Eggert <eggert@twinsun.com>
6031 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
6032 inside '#ifndef __cplusplus'. Problem reported by
6033 Bob Friesenhahn.
6035 2003-07-06 Bill Clarke <llib@computer.org>
6037 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
6038 'long', not 'int', for benefit of Sun's recent C++ compilers
6039 (trivial change). See:
6040 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
6041 (This really should be 'intptr_t', not 'long', but that would
6042 take more work.)
6044 2003-06-25 Akim Demaille <akim@epita.fr>
6046 * lib/Makefile.am (autom4te.cfg): Make it read only.
6047 Depend on Makefile since it contains substitutions.
6048 From Paolo Bonzini.

6056 From Gareth McCaughan.
6058 2003-06-23 Akim Demaille <akim@epita.fr>
6060 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6061 not all of them. This fixes 1. the fact that when testing
6062 Autoconf there are many many config.log, 2. the incorrect use of
6063 top_srcdir to find config.log.
6064 Don't mix the detailed output of failed test with the summary of
6065 failures. Rather, append detailed log afterwards.
6067 2003-06-23 Akim Demaille <akim@epita.fr>
6069 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
6070 always run: output config.log on $at_group_log.
6072 2003-06-23 Akim Demaille <akim@epita.fr>
6074 * tests/torture.at (#define header templates): Don't use quotes in

6079 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
6080 * lib/autom4te.cfg (args): Add local.at? for Autotest args.

6088 2003-06-21 Kevin Ryde <user42@zip.com.au>
6090 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
6091 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
6092 ensuring we add -std1 for full-ANSI.
6094 * doc/autoconf.texi (hdrindex): New macro.

6097 2003-06-20 Akim Demaille <akim@epita.fr>

6101 2003-06-20 Akim Demaille <akim@epita.fr>
6103 Version 2.57a.
6105 2003-06-20 Akim Demaille <akim@epita.fr>
6107 * bin/autom4te.in: Don't rely on $HOME being defined.
6108 Reported by Marc Espie as PR/233.
6110 2003-06-20 Akim Demaille <akim@epita.fr>
6112 * lib/autotest/general.m4: Use at_times_file only if used.
6113 From Nicolas Joly.

6119 Update from masters.
6121 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6123 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6124 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6125 (TEST_SCRIPT): New diversion.
6126 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6127 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6128 (AT_INIT): Support for expected failures.
6130 2003-06-02 Akim Demaille <akim@epita.fr>
6132 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6133 changes.
6134 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6135 Autoconf nor Automake.
6136 (&contents): New, from Automake.
6137 PODify.
6139 2003-05-28 Paul Eggert <eggert@twinsun.com>
6141 * NEWS, doc/autoconf.texi (Particular Functions),
6142 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6143 is the inverse of localtime.
6145 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6147 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6148 (handle_exec_errors): New function. Work around $! being
6149 altered by WEXITSTATUS.
6150 (xqx, xsystem): Use handle_exec_errors.
6152 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6154 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6155 Do not call `_exit()', simply modify `$?'.
6156 (xsystem): Reset $! before running system, and check it afterward.
6157 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6158 63 for version mismatches.
6160 2003-05-23 Akim Demaille <akim@epita.fr>
6162 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6163 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6164 the middle of a line).
6165 * lib/m4sugar/m4sugar.m4: Likewise.
6166 Remove useless spaces in comments.
6168 2003-05-23 Akim Demaille <akim@epita.fr>
6170 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6171 exit 63, so that we (or Automake's "missing") can tell the
6172 difference with a plain failure.
6173 * doc/autoconf.texi (Notices): Adjust.
6175 2003-05-23 Akim Demaille <akim@epita.fr>
6177 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6178 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6179 White spaces cleanup.
6181 2003-05-22 Jim Meyering <jim@meyering.net>
6182 Paul Eggert <eggert@twinsun.com>
6184 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6185 Remove `#include <stdlib.h>' from the list; we should never
6186 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6187 resulting namespace pollution would cause other tests to fail.
6188 Configure scripts run with some older versions of g++ and HP's
6189 aCC would fail due to such an #include. Problems reported by
6190 Matthew Mueller in <http://bugs.debian.org/120704> and by
6191 Keith Bostic in
6192 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6193 In the test, use the test declaration before including <stdlib.h>,
6194 as that's closer to how it'll be used.
6196 2003-05-23 Akim Demaille <akim@epita.fr>
6198 * doc/autoconf.texi (Header Portability): ucred.h.
6199 From Ian Redfern.
6201 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6203 Overhaul Autotest's logging: generate separate log files
6204 in testsuite.dir/NNN/testsuite.log, and append them to
6205 testsuite.log instead of re-running the test verbosely.
6207 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6208 file descriptor, write 0 to at_status_file instead of setting
6209 at_status=0, initialize some new variables (at_status_file,
6210 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6211 to rerun the tests, instead append the at_group_log to the
6212 at_suite_log when a test fails.
6213 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6214 with the AS_MESSAGE_LOG_FD redirected to stdout.
6215 (AT_CLEANUP): save the output status in $at_status_file
6216 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6217 its original place.
6218 (AT_CHECK): since tests are run with a redirected stdout,
6219 and used to be re-run in verbose mode, turn some $at_verbose
6220 into echo, and don't redirect the output of testing stdout
6221 and stderr.
6223 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6224 the name of the debugging directory and information about
6225 its contents.
6227 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6229 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6230 parameter.
6232 2003-05-22 Akim Demaille <akim@epita.fr>
6234 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
6235 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
6236 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

6253 Suggested by Jim Meyering.
6255 2003-05-22 Akim Demaille <akim@epita.fr>
6257 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
6258 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
6259 Reported by Jim Meyering.
6261 2003-05-22 Akim Demaille <akim@epita.fr>
6263 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

6265 Typos.
6266 Use '@.' for sentences that ended in a capital letter.
6267 From Art Haas.

6296 2003-05-17 Akim Demaille <akim@epita.fr>
6298 * lib/autoconf/functions.m4: Use the default includes so that
6299 memcmp be declared before being tested.
6300 Reported by Sander Niemeijer.
6301 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

6303 AC_INCLUDES_DEFAULT.
6305 2003-05-17 Akim Demaille <akim@epita.fr>
6307 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
6308 * doc/autoconf.texi (Obsolete Macros): Adjust.
6309 Reported by Werner LEMBERG and Debian Bug 190886.
6311 2003-05-16 Akim Demaille <akim@epita.fr>
6313 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
6314 user name space clashes.
6315 Reported by Bruno Haible.
6317 2003-05-16 Akim Demaille <akim@epita.fr>
6319 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6320 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
6321 them uniform, and more robust to Perl special characters.
6322 Reported by Martin Mokrejs.
6324 2003-05-14 Akim Demaille <akim@epita.fr>
6326 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
6328 2003-05-14 Akim Demaille <akim@epita.fr>
6330 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

6335 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
6336 message.
6337 From Matthias Andree.
6339 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
6341 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
6342 and truncate.
6344 2003-05-06 Akim Demaille <akim@epita.fr>
6346 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6347 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6348 by aclocal.m4 is changed it might require the importing of another
6349 m4 extension file, i.e., aclocal must be run.
6351 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6352 (&parse_args): Use --force with aclocal if required and supported.
6353 (&autoreconf_current_directory): Use &run_aclocal.
6355 2003-05-06 Akim Demaille <akim@epita.fr>
6357 Lock autom4te's cache.
6359 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
6360 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6361 argument instead of a file name, so that the request file remains
6362 open during the whole autom4te run.
6363 ($icache_file): New.
6364 (&freeze): Lock the $icache_file.
6366 2003-04-29 Derek Price <derek@ximbiot.com>
6368 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6369 seperator with m4_append_uniq(). It doesn't work.
6370 (AT_CLEANUP): Add `;' to end of at_help_all.
6371 (AT_INIT): Allow --keywords to be specified more than once. When
6372 grepping $at_help_all for keywords, use the field and keyword
6373 seperators to ensure a complete keyword match. Alter at_prev handling
6374 to support the new --keywords behavior.
6376 2003-04-27 Karl Berry <karl@freefriends.org>
6378 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6379 align better with others. I also made some of the individual
6380 entries on one line, for brevity and to make it easier for me to
6381 sort my dir-example file in the Texinfo distribution :).
6383 2003-04-12 Jim Meyering <jim@meyering.net>
6385 * NEWS: Mention the new macro.

6479 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
6480 * tests/m4sh.at (AS_HELP_STRING): New test.
6482 * tests/acgeneral.at: Regenerated.
6484 2003-03-26 Derek Price <derek@ximbiot.com>
6486 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
6487 sense. Verbosify the diversion definitions comment.

6527 (Automake): Automake 1.5+ no longer requires special tools to be
6528 present on the developer's host.
6530 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>

6537 * bin/autoreconf.in (BEGIN): Likewise.
6538 * bin/autoscan.in (BEGIN): Likewise.
6539 * bin/autoupdate.in (BEGIN): Likewise.

6544 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
6545 to cope with DOS-style absolute paths, when constructing
6546 ${ac_make}.
6548 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6549 When constructing paths with IFS=:, quote the path. If we're
6550 constructing a DOS-style absolute path, we don't want to split it
6551 on the colon.
6553 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
6554 in description.
6556 2003-02-25 Pavel Roskin <proski@gnu.org>

6568 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
6569 to fix a mismatch between example and discussion.
6571 2003-02-24 Kevin Ryde <user42@zip.com.au>
6573 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6574 format starting with "-".
6576 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6578 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6579 is not portable inside Makefile.
6581 2003-02-20 Akim Demaille <akim@epita.fr>
6583 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6584 compiler says yeah, but preproc says nope, compiler is right.
6585 Conversely, prompt the reader to send a bug report to the
6586 maintainers of the package, not of Autoconf.
6588 2003-02-20 Klee Dienes <kdienes@apple.com>
6590 * bin/autoreconf.in (autoreconf_current_directory): Properly
6591 handle an empty aclocal.m4.

6596 $ac_prefix_program.
6597 From Larry Jones.
6599 2002-12-23 Paul Eggert <eggert@twinsun.com>
6601 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6602 innocuous variant befor including <limits.h> or <assert.h>. This
6603 works around a bug reported by Albert Chin: HP-UX 11i
6604 (and earlier versions) have a <limits.h> that declares
6605 gettimeofday and many other functions.
6607 2002-12-03 Paul Eggert <eggert@twinsun.com>
6609 Version 2.57.
6611 * NEWS, configure.ac: Update version.
6613 * doc/fdl.texi: Upgrade to FDL version 1.2.
6615 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6616 nontrivially in main's body, so that f's external declaration is
6617 not optimized away in AIX. This should fix the bug reported by
6618 Martin Frydl in
6619 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6621 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6622 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6623 defined, to support freestanding compilers. This should fix the
6624 bug reported by Momchil Velkov in
6625 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6627 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6628 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

6633 * Makefile.maint (www-gnu): New macro.
6634 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6635 the location has moved.
6637 2002-12-02 Martin Frydl <martin@systinet.com>
6639 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6640 \(.*\) match is too long and there is something more to be checked.
6641 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
6643 2002-11-15 Akim Demaille <akim@epita.fr>

6649 * config/move-if-change: Indenting changes.
6650 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
6651 * configure.ac (AM_INIT_AUTOMAKE): here.
6652 Require 1.7.1.
6654 2002-11-14 Akim Demaille <akim@epita.fr>
6656 Version 2.55.
6658 * config/config.guess, config/config.sub, config/install-sh:
6659 Update from masters.
6661 2002-11-14 Akim Demaille <akim@epita.fr>
6663 * Makefile.maint: Sync with Bison, i.e.:
6664 (po-check): Scan .l and .y files instead of the
6665 .c and the .h files that they generate. This fixes the bug
6666 reported by Tim Van Holder in:
6667 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6668 Look for N_ as well as for _. Try to avoid matching #define for
6669 N_ and _.
6670 From Paul Eggert.
6672 2002-11-14 Akim Demaille <akim@epita.fr>
6674 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6675 From Paul Eggert and Albert Chin-A-Young.
6677 2002-11-14 Akim Demaille <akim@epita.fr>
6679 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6680 From Paul Eggert and Albert Chin-A-Young.
6682 2002-11-14 Kevin Ryde <user42@zip.com.au>
6684 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6685 than assigning in main, to avoid HP cc +O3 optimizing it away.
6687 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6689 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6690 option. Process --recheck after parsing all options. Pass -q
6691 option to configure on --recheck.
6692 (AC_OUTPUT): Pass -q from configure to config.status.
6693 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6694 arguments to record.
6695 * doc/autoconf.texi (config.status Invocation): Document
6696 config.status -q option.
6698 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
6700 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
6701 Makefile.in if Makefile.am exists.
6702 (output): Strip `.am' from Makefiles. Don't
6703 output AC_CONFIG_FILES if no Makefiles were found.
6705 2002-11-07 Akim Demaille <akim@epita.fr>

6712 2002-11-06 Akim Demaille <akim@epita.fr>
6714 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
6715 declaration in extern "C" too.

6718 2002-11-06 Akim Demaille <akim@epita.fr>
6720 * tests/torture.at (Configuring subdirectories): Don't use grep
6721 -w.
6722 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
6723 Reported by Ezra Peisach.
6725 2002-11-05 Akim Demaille <akim@epita.fr>
6727 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6728 Remove.
6729 We _have_ to stop using the old compatibility scheme that tried to
6730 avoid useless backslashes because Libtool 1.4.3 contains a
6731 AC_DEFINE([error_t], [int],
6732 [Define to a type to use for \`error_t' if it is not
6733 otherwise available.])
6734 We _have_ to quote the single quote and backslashes with \. The
6735 old compatibility scheme saw that ` was backslashed, and therefore
6736 did not quote the single quote. Hence before this patch, Autoconf
6737 was not compatible with Libtool.
6739 2002-11-04 Paul Eggert <eggert@twinsun.com>
6741 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6746 2002-11-04 Akim Demaille <akim@epita.fr>
6748 Version 2.54c.
6750 * Makefile.maint (update, cvs-update, po-update, do-po-update):
6751 New.
6752 * config/texinfo.tex: Update.
6754 2002-11-03 Akim Demaille <akim@epita.fr>
6756 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
6757 from...
6758 (&autoreconf): here.
6759 ($help, $make, &parse_args, &autoreconf_current_directory):
6760 Support -m/--make.
6761 * doc/autoconf.texi (autoreconf Invocation): Adjust.

6776 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
6777 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
6779 2002-10-31 Akim Demaille <akim@epita.fr>
6781 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6782 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6783 Make variable, not a shell variable.
6784 Suggested by Bruno Haible.
6786 2002-10-31 Akim Demaille <akim@epita.fr>
6788 * bin/autom4te.in (load_configuration): Reject #args out of any
6789 language.
6791 2002-10-31 Akim Demaille <akim@epita.fr>
6793 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
6794 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
6795 (_AC_RUN_IFELSE): Use it.
6796 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
6797 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
6798 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
6799 inline it.

6805 Suggested by Tim van Holder.
6807 2002-10-29 Paul Eggert <eggert@twinsun.com>
6809 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
6810 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
6811 Problem reported by Bruno Haible.
6813 2002-10-29 Akim Demaille <akim@epita.fr>
6815 * doc/autoconf.texi (Header Templates): Put also in words what the
6816 pictures says to assist free style readers.
6817 (Customizing autom4te): s/--cache=/--cache /.
6819 2002-10-29 Akim Demaille <akim@epita.fr>
6821 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
6822 sys/wait.h.
6823 sparc_address_test returns void.
6824 Use it with an argument, as prototyped.
6825 From Bruno Haible.
6827 2002-10-29 Akim Demaille <akim@epita.fr>
6829 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

6835 * tests/torture.at (Deep Package): New test.

6841 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
6842 * doc/autoconf.texi (Invoking autom4te): Rename as...
6843 (autom4te Invocation): this, for consistency with the other nodes.
6845 2002-10-29 Akim Demaille <akim@epita.fr>
6847 * lib/autom4te.in (Autoconf): s/automate/autom4te/.
6848 Reported by Ralf Corsepius.
6850 2002-10-29 Akim Demaille <akim@epita.fr>
6852 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

6858 * configure.ac: Bump to 2.54c.

7069 2002-10-22 Akim Demaille <akim@epita.fr>
7071 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

7128 Reported by Alexandre Duret-Lutz.
7130 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7131 to frozen files in @ARGV, as @ARGV must remain being a list of

7133 (&files_to_options): New function.
7134 (&freeze): Use &error.
7135 (&up_to_date): If a file that was included according to the cache
7136 is no longer there, then the output is out dated.
7137 (&main): Don't even check whether a file is up to date is anyway
7138 --force is given.
7139 * tests/tools.at (autom4te cache): New.

7148 that error messages can be easily located, and use GNU Make
7149 format, so that Emacs' compile mode understands us.
7150 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7151 if some file was changed instead of `print'.
7152 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

7186 file name to enable parallel executions.
7187 From Sam Varshavchik.
7189 2002-10-08 Akim Demaille <akim@epita.fr>
7191 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7192 aclocal invocation, as Gettext macros might not be visible to
7193 aclocal.
7194 Instead of blindly running autopoint, scan configure.ac (not the
7195 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7196 Reported by Paul D. Smith.
7198 2002-10-08 Paul Eggert <eggert@twinsun.com>
7200 Work around problems found when POSIXLY_CORRECT=1 is set.
7201 None of this seems to have anything to do with POSIX, really,

7203 * bin/autom4te.in (parse_args): Configure GetOpt with
7204 "permute", too.
7205 * doc/autoconf.texi (Invoking autom4te):

7228 * tests/torture.at (Configuring subdirectories): Be robust to
7229 users who use config.site to require for a cache: in this case,
7230 the two last configure runs, using two different sets of
7231 arguments, trigger a legitimate error.
7233 2002-09-28 Akim Demaille <akim@epita.fr>

7252 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7253 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

7268 tests/autom4te itself.
7269 * lib/autoscan/Makefile.am: Include freeze.mk.
7270 (autoscan.list): New target --this file is no longer a source.
7271 (autoscan.pre): New file.

7278 tracking changes in autoscan.list.
7279 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7281 2002-09-28 Akim Demaille <akim@epita.fr>

7295 * bin/autoscan.in (&init_tables): Adjust.
7297 2002-09-28 Akim Demaille <akim@epita.fr>
7299 From now on, autoscan files must always map a macro name to a
7300 word: there is no `default' macro for autoscan.
7302 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7303 all.
7304 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7305 explicit.
7307 2002-09-28 Akim Demaille <akim@epita.fr>
7309 * bin/autoscan.in (%c_keywords): Remove.

7343 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7345 2002-09-26 Akim Demaille <akim@epita.fr>
7347 Single suffix rules and seperated dependencies are not portable.

7377 2002-09-13 Paul Eggert <eggert@twinsun.com>
7379 * doc/autoconf.texi (Particular Headers): Remove obsolete
7380 reference to `struct timezone' in the description of
7381 AC_HEADER_TIME.
7383 2002-09-13 Akim Demaille <akim@epita.fr>
7385 Version 2.54.
7387 * config/config.sub, config/config.guess: Update.
7388 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7389 * Makefile.am: Adjust.
7391 2002-09-13 Akim Demaille <akim@epita.fr>
7393 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7394 reading config.log when the compiler is rejected.
7395 Suggested by Guido Draheim.
7397 2002-09-13 Akim Demaille <akim@epita.fr>
7399 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7400 (chdir_init) might hang when stat'ing mounted directories.
7401 Reported by Vance Shipley.
7403 2002-09-12 Akim Demaille <akim@epita.fr>
7405 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7406 the lists.
7408 2002-09-12 Akim Demaille <akim@epita.fr>
7410 * doc/autoconf.texi (Defining Symbols): Present two different
7411 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7412 difference between 1 argument calls, and 2-3 argument calls.
7414 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7416 * doc/autoconf.texi: Review grammar and punctuation.
7418 2002-09-11 Paul Eggert <eggert@twinsun.com>
7420 * doc/autoconf.texi: Fix minor formatting, spelling, and
7421 grammatical typos.
7422 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7423 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7424 is obsolescent.
7426 2002-09-11 Akim Demaille <akim@epita.fr>
7428 * doc/autoconf.texi (Questions): Rename as...
7429 (FAQ): this.
7430 (Defining Directories): New.
7432 2002-09-09 Akim Demaille <akim@epita.fr>
7434 * doc/autoconf.texi (Making testsuite Scripts): Update.
7435 Suggested by Nishio Futoshi.
7437 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7439 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7440 plain `@' is wanted.
7442 2002-09-09 Akim Demaille <akim@epita.fr>
7444 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7445 `duplicates', since the algorithm was too naive and could keep
7446 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7447 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7448 Reported by Ralf Corsepius.
7449 * tests/torture.at (Configuring subdirectories): Exercise these
7450 cases.
7452 2002-09-09 Akim Demaille <akim@epita.fr>
7454 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7455 looking for a replacement file.
7456 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7457 directory is relative.
7458 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7459 directory definition.
7460 Reported by Andreas Schwab and Jim Meyering.
7462 2002-09-06 Akim Demaille <akim@epita.fr>
7464 * doc/autoconf.texi (Setting Output Variables): Clarify what
7465 precious variables are.
7466 Suggested by Pontus Skoeld.
7468 2002-09-05 Akim Demaille <akim@epita.fr>
7470 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7471 (ifnames, autoscan, autom4te): Since we don't only depend on
7472 configure.ac variables (such as VERSION etc.), but also on prefix
7473 and so forth, depend on Makefile, not configure.ac.
7474 Reported by Alexandre Duret-Lutz.
7475 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7477 2002-09-05 Kevin Ryde <user42@zip.com.au>
7479 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7480 doesn't seem to be confined to ia64, just say "some versions".
7482 2002-09-04 Akim Demaille <akim@epita.fr>
7484 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7485 Automake 1.6c.
7486 * Makefile.am (maintainer-clean-local): Remove.
7487 (MAINTAINERCLEANFILES): Remove COPYING.
7489 2002-09-03 Paul Eggert <eggert@twinsun.com>
7491 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7492 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7493 Brinkmann.
7495 2002-09-03 Akim Demaille <akim@epita.fr>
7497 * configure.ac: Bump to 2.53d.
7498 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7499 as of today, on Automake's team suggestion.
7501 2002-09-03 Akim Demaille <akim@epita.fr>
7503 Version 2.53c.
7505 2002-09-02 Akim Demaille <akim@epita.fr>
7507 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7508 SITE_MACRO_DIR.
7509 * configure.ac: Disable SITE_MACRO_DIR.
7511 2002-09-02 Jim Meyering <meyering@lucent.com>
7513 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7514 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7515 Also, tweak grammar: s/make sure to/be sure to/.
7517 2002-09-02 Paul Eggert <eggert@twinsun.com>
7519 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7520 directory names are generally preferable to physical names.
7522 2002-09-02 Akim Demaille <akim@epita.fr>
7524 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7525 Reported by Raja R. Harinath.
7526 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7527 * bin/autoupdate.in: Use error instead of die.
7529 2002-09-01 Paul Eggert <eggert@twinsun.com>
7531 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7532 ordinary shell concatenation rather than echo+tr+sed command that
7533 runs afoul of a long-line-related sed bug in Solaris 8.
7535 * bin/autoheader.in (parse_args): --warning -> --warnings.
7537 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7538 stdout, as traditional "ls" does.
7539 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7540 _AC_COMPILER_EXEEXT_O): Likewise.
7541 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7543 * bin/autoconf.as: Add --prepend-include option. This patch was
7544 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7545 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7547 * bin/autoconf.in, configure: Regenerate.
7549 * doc/autoconf.texi (Special Shell Variables): Mention
7550 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7552 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7553 MAILPATH and set PS1, PS2, PS4 to default values, to work
7554 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7555 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7556 the Autoconf documentation specifies; fall back to "unset" only if
7557 this fails. Use a shell for-loop for this rather than an m4 loop,
7558 to shorten the output script.
7560 2002-08-30 Paul Eggert <eggert@twinsun.com>
7562 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7563 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7564 for the CDPATH problem. Document PWD.
7565 (Limitations of Builtins): Document the problem that "cd $foo" and
7566 "ls $foo" may refer to different directories in shells conforming
7567 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7568 example, since the old example is now out of date.
7570 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7571 FOO" and "ls FOO" talk about different directories; this catches
7572 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7573 spaghetti.
7575 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7576 of rolling our own unset.
7577 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7578 in practice we needn't worry about CDPATH if unset doesn't work.
7580 * Makefile.in, aclocal.m4, bin/Makefile.in,
7581 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7582 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7583 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7584 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7585 tests/Makefile.in: Regenerate with Automake 1.6.3.
7587 * config/config.guess, config/config.sub, config/mkinstalldirs:
7588 Update.
7590 * configure: Regenerate with self.
7592 2002-08-30 Kevin Ryde <user42@zip.com.au>
7594 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7595 default output.
7597 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7599 * bin/autom4te.in (Request::load): Correctly test for "do" read
7600 failure.
7602 2002-08-29 Akim Demaille <akim@epita.fr>
7604 * lib/Autom4te/General.pm (&xqx): New.
7605 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7606 hand, which is not portable.
7607 (&error): New.
7608 * bin/autom4te.in: Use them.
7609 Use &error instead of die.
7610 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7611 Adjust.
7613 2002-08-17 Paul Eggert <eggert@twinsun.com>
7615 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7616 default list of compilers to try, since it was long ago superseded
7617 by the ksh fc builtin. Suggested by Steven G. Johnson.
7619 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7621 * doc/autoconf.texi (Invoking autom4te): End the option table,
7622 fixing a bug introduced by the previous patch.
7623 (Limitations of Make): Add a 'target lookup' subentry in the
7624 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7626 2002-07-29 Mark D. Roth <roth@feep.net>
7628 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7629 options and use $AUTOM4TE_PATH.
7630 * doc/autoconf.texi: Remove documentation of autom4te
7631 --include-envvar and --site-macro-subdir options and document
7632 use of $AUTOM4TE_PATH.
7633 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7634 arguments from each language section.
7636 2002-07-29 Paul Eggert <eggert@twinsun.com>
7638 * doc/install.texi: Include copyright symbol in copyright notice.
7640 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7641 Replace with:
7642 (AM_MAKEINFOFLAGS): New macro.
7643 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7644 * Makefile.am (INSTALL): Use the new macros.
7645 Use -o rather than --output, since "missing" does not grok --output.
7647 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7649 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7650 comments do not always work. Never trust the exit status of
7651 `make -k'.
7653 2002-07-24 Kevin Ryde <user42@zip.com.au>
7655 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7656 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7658 2002-07-23 Paul Eggert <eggert@twinsun.com>
7660 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7661 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7662 apparently treats PATH="nonexistent" as if it contained ".".
7663 Bug reported by Stefan `Sec' Zehl.
7665 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7667 * doc/autoconf.texi (Limitations of Make): Mention the special
7668 handling of the obj/ directory by BSD make.

7684 2002-07-18 Akim Demaille <akim@epita.fr>
7686 Version 2.53b.
7688 2002-07-18 Akim Demaille <akim@epita.fr>
7690 * config/config.guess, config/config.sub: Update.
7692 2002-07-18 Akim Demaille <akim@epita.fr>
7694 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
7695 Automake's parts.

7698 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
7699 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
7701 2002-07-18 Akim Demaille <akim@epita.fr>,
7702 Alexandre Duret-Lutz <duret_g@epita.fr>
7704 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

7710 description of the tarname default.

7714 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
7715 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
7716 latter was not run.
7718 2002-07-17 Akim Demaille <akim@epita.fr>
7720 * lib/Autom4te/General.pm (find_file): Browse the directories in
7721 the order they are given.

7789 2002-06-27 Paul Eggert <eggert@twinsun.com>

7794 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7796 * tests/mktests.sh: Use grep instead of fgrep, as per
7797 "Limitations of Builtins".
7799 2002-06-15 Paul Eggert <eggert@twinsun.com>
7801 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7802 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7803 so that we consistently test the just-built programs.
7804 * tests/wrappl.as: Likewise.
7806 2002-06-12 Paul Eggert <eggert@twinsun.com>
7808 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
7809 name, so that symlinks to 'autoconf' work properly. Bug reported
7810 by Bruno Haible.
7811 * bin/autoheader.in (AUTOM4TE): Likewise.
7812 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7813 * bin/autoscan.in (autom4te): Likewise.
7814 * bin/autoupdate.in (autom4te): Likewise.
7816 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7817 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7818 on Solaris 2.5.1.
7820 2002-06-11 Andreas Schwab <schwab@suse.de>
7822 * doc/autoconf.texi: Add more dir entries.
7824 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7826 * bin/autom4te.in ($cache): Don't define using `$me', the name
7827 of the cache should not depend on the name under which autom4te
7828 was installed.
7830 2002-06-07 Akim Demaille <akim@epita.fr>
7832 * tests/tools.at (autoconf: forbidden tokens, basic)
7833 (autoconf: forbidden tokens, exceptions): Adjust to the change of
7834 words in autom4te.in.
7836 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7838 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use

7869 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
7870 (AC_REPLACE_FNMATCH_GNU): these.
7871 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
7872 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
7873 * tests/mktests.sh (ac_exclude_list): Don't check
7874 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
7876 2002-06-06 Paul Eggert <eggert@twinsun.com>
7878 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7879 if ln doesn't work.
7880 * NEWS: Likewise.
7881 * doc/autoconf.texi (Configuration Links): Likewise.
7882 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
7884 2002-06-05 Paul Eggert <eggert@twinsun.com>
7886 * config/config.guess, config/config.sub, config/texinfo.tex:
7887 Update from masters.
7889 2002-05-29 Paul Eggert <eggert@twinsun.com>
7891 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
7892 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
7893 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):
7894 Likewise.
7895 * lib/autoconf/Makefile.am (check-local): Likewise.

7904 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
7905 * doc/autoconf.texi (Particular Programs): Document them.
7906 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
7907 * NEWS: Likewise.
7909 2002-05-27 Paul Eggert <eggert@twinsun.com>
7911 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
7912 * NEWS, doc/autoconf.texi (Particular Types): Document it.
7913 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
7914 instead of AC_MBSTATE_T, which never existed.
7916 2002-05-23 Akim Demaille <akim@epita.fr>
7918 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7919 version of Autoconf that is discussed.
7921 2002-05-22 Paul Eggert <eggert@twinsun.com>
7923 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7924 from the default list of compilers to try. Suggested by
7925 Kate Hedstrom.
7926 * NEWS: Document the above.
7927 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7929 2002-05-17 Paul Eggert <eggert@twinsun.com>
7931 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7932 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7933 This improves on an earlier suggestion by H. Peter Anvin.
7935 2002-05-16 Paul Eggert <eggert@twinsun.com>
7937 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7938 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7939 Both macros now accept an optional source-dir arg.
7940 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7942 * NEWS: Document this.
7943 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7945 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7946 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7947 not for GNU extensions; this undoes part of the 2000-11-03 change,
7948 reverting to 2.13-compatible behavior.
7949 Add new optional argument DIR.
7950 (AC_FUNC_FNMATCH_GNU): New macro.
7952 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7954 2002-05-08 Paul Eggert <eggert@twinsun.com>
7956 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7957 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7958 and it causes a 'test' syntax error if it fails.
7959 Bug reported by Stephen Gildea.
7961 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7962 If prototypes are supported, use them to check this at compile-time,
7963 instead of trying to check it at run-time. If we must do a run-time
7964 check, assume that setvbuf is standard when cross-compiling, as
7965 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7966 Bug reported by Paul D. Smith.
7968 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7969 argument specifying location of getloadavg.c. This removes a
7970 FIXME. This idea was taken from Jim Meyering's implementation in
7971 textutils.
7972 * doc/autoconf.texi (Particular Functions): Document this.
7973 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7974 that's what the code does; this fixes a bug reported by
7975 Paul D. Smith.
7977 2002-05-03 Akim Demaille <akim@epita.fr>
7979 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7980 autopoint instead of gettextize.
7981 ($uses_alocal): Rename as...
7982 ($uses_aclocal): this.
7983 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7984 Suggested by Bruno Haible.
7986 2002-05-03 Akim Demaille <akim@epita.fr>
7988 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7990 2002-04-29 Paul Eggert <eggert@twinsun.com>
7992 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7993 files to be 1 second older; just set them to be the same time.
7994 Also, sleep 1 second after the first aclocal, to work around
7995 problems with sub-second time stamps on the input files.
7997 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7999 * doc/autoconf.texi: Mention "set -e -x" lossage
8000 under node "Limitations of Builtins".
8002 2002-04-29 Akim Demaille <akim@epita.fr>
8004 * doc/install.texi: Better wording for setting variables when
8005 running configure.
8006 From Christian Cornelssen.
8008 2002-04-29 Akim Demaille <akim@epita.fr>
8010 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8011 of lack of $LINENO support, then the test will compare the $LINENO
8012 in testsuite vs. the lineno in the test file. This is wrong, of
8013 course.
8014 Be sure to protect it.
8015 Reported by Patrick Welche.
8017 2002-04-25 Akim Demaille <akim@epita.fr>
8019 * doc/autoconf.texi (Obsolete Macros): Typo.
8020 Reported by Vladimir Volovich.
8022 2002-04-25 Akim Demaille <akim@epita.fr>
8024 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8025 than some of the input files, hence, on the second run of aclocal,
8026 if some of its input are younger, make them older.
8027 Suggested by Paul Eggert.
8029 2002-04-25 Akim Demaille <akim@epita.fr>
8031 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8032 Thanks to Paul Eggert.
8034 2002-04-25 Akim Demaille <akim@epita.fr>
8036 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8037 and ac_subst_vars be sh variables containing the list of
8038 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8039 DEFAULT diversion.
8040 (_AC_INIT_PREPARE): Use them to log them.
8041 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8042 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8043 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8044 _AC_SUBST_FILES and _AC_SUBST_VARS.
8045 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8047 2002-04-24 Akim Demaille <akim@epita.fr>
8049 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8050 autoheader, so that automake does not complain about a missing
8051 config.h.in that was to be created.
8053 2002-04-23 Akim Demaille <akim@epita.fr>
8055 * bin/autoheader.in (parse_args): --warning takes an argument.
8056 Fixes PR/220.
8058 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
8060 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
8061 and bb.out when cleaning up.
8063 2002-04-22 Akim Demaille <akim@epita.fr>
8065 Version 2.53a.
8067 2002-04-22 Akim Demaille <akim@epita.fr>
8069 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
8071 2002-04-22 Akim Demaille <akim@epita.fr>
8073 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
8074 comma.
8075 Reported by Gregory Giannoni.
8077 2002-04-22 Akim Demaille <akim@epita.fr>
8079 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
8080 Fixes false failures on Darwin.
8082 2002-04-21 Paul Eggert <eggert@twinsun.com>

8086 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

8105 Minor spelling and grammar fixes.
8107 * doc/autoconf.texi: Follow the outline suggested in the GNU
8108 Sample Texts sections of the Texinfo 4.2 manual. Most
8109 importantly, this makes sure that the copyright notices appear in
8110 all output formats. You probably need Texinfo 4.2 to generate
8111 the manual now.
8113 Fix some bugs when using "$@" when there might be zero positional
8114 arguments in cases where this matters.

8134 * tests/c.at: We can't have zero arguments, so remove workaround
8135 that is not portable to Zsh.
8137 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8139 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8140 from aclocal.m4 too.
8142 2002-04-12 Akim Demaille <akim@epita.fr>
8144 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
8146 2002-04-10 Akim Demaille <akim@epita.fr>
8148 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8149 workaround for ${1+"$@"}.
8150 * doc/autoconf.texi (Shell Substitutions): Explain it.
8151 From Oliver Kiddle and Peter Stephenson.
8153 Have M4sh perform minimal shell sanitizing.
8155 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8156 part into...
8157 (_AS_PREPARE): this new macro.
8158 (AS_PREPARE): New.
8159 (AS_INIT): Invoke AS_SHELL_SANITIZE.
8160 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8162 Adjust Autoconf and Autotest.
8164 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8165 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8166 * lib/autotest/general.m4 (AT_INIT): Likewise.
8167 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8168 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8169 AS_SHELL_SANITIZE.
8171 Use this M4sh to generate Autoconf's shell scripts.
8173 * tests/wrapsh.as: New, precursor of wrapsh.in.
8174 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8175 on Autotest and M4sh.
8176 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8177 (wrapsh.in): New target.
8178 * bin/autoconf.as: New, precursor of autoconf.in.
8179 (autoconf.in): New target.
8181 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

8184 with indented comments in rules.
8186 2002-04-09 Andreas Schwab <schwab@suse.de>
8188 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
8189 ac_top_builddir when setting ac_abs_top_builddir.
8191 2002-04-06 Kevin Ryde <user42@zip.com.au>
8193 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
8194 (Portable Shell): Cross reference to Systemology.
8196 2002-04-05 Akim Demaille <akim@epita.fr>
8198 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8199 directories when descending in a SUBDIRS.
8200 Reported by Ezra Peisach.
8202 2002-04-04 Andreas Schwab <schwab@suse.de>
8204 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8205 contains no literal separators.
8207 2002-04-03 Akim Demaille <akim@epita.fr>
8209 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8210 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8211 Use dnl, not the KILL diversion.
8212 Extracted from...
8213 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8214 (AC_CONFIG_LINKS): here.
8215 Adjust.
8216 Don't use the KILL diversion, as it kills spurious output, which
8217 results in failures being hidden.
8218 Use m4_defn where appropriate.
8219 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8220 after the second argument.
8221 Use m4_defn.
8222 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8223 syntax, as it is provided by M4sugar.
8224 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
8226 2002-04-03 Andreas Schwab <schwab@suse.de>
8228 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not

8232 aclocal.
8234 2002-04-03 Akim Demaille <akim@epita.fr>

8239 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
8240 (_AC_COMPILER_OBJEXT): Use them.
8241 Fixes Debian #138666.
8243 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
8245 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
8247 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
8248 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
8249 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
8250 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
8251 (AC_C_CONST): Same.

8261 _AS_MKDIR_P_PREPARE.
8263 2002-03-28 Kevin Ryde <user42@zip.com.au>
8265 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8266 to avoid versions of HP C which don't allow that.
8268 2002-03-27 Paul Eggert <eggert@twinsun.com>
8270 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

8282 2002-03-25 Paul Eggert <eggert@twinsun.com>
8284 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8285 as POSIX requires, as it doesn't work with Zsh.
8286 * doc/autoconf.texi (Assignments): Document the problem.
8288 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8290 * doc/autoconf.texi (Limitations of Make): Mention more issue
8291 about VPATH, overriding of macros in sub-makes, and handling of
8292 SHELL.
8294 2002-03-21 Paul Eggert <eggert@twinsun.com>
8296 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8297 problem with here-document buffer boundaries.
8299 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8300 when reinvoking the shell, to work around problems with installers
8301 who put strange things like "cd" commands in their environments.
8303 2002-03-19 Akim Demaille <akim@epita.fr>

8317 From Nishio Futoshi.
8319 2002-03-19 Akim Demaille <akim@epita.fr>
8321 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8323 2002-03-18 Paul Eggert <eggert@twinsun.com>
8325 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8326 (Limitations of Usual Tools): Add mkdir section.
8328 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8329 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8330 back on AS_DIRNAME to compute prefixes otherwise; this is
8331 roughly what mkinstalldirs does. That way, we need not have
8332 our own filename disassembler. The old disassembler did not
8333 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8335 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8336 Create at_test_all by a series of assignments,
8337 not by a single assignment of a long string. The latter causes ksh
8338 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8339 presumably because of a buffer overrun.
8341 2002-03-14 Paul Eggert <eggert@twinsun.com>
8343 * lib/autotest/general.m4 (at_times_skip):
8344 Renamed from at_times. Now a boolean.
8345 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8346 says 'times: not found'.

8396 aliases the actual variables, and modifications of the former
8397 affect the latter.

8401 * bin/autom4te.in (&handle_m4): Protect us from corrupted file

8432 parallel builds.
8434 2002-03-04 Akim Demaille <akim@epita.fr>
8436 * doc/autoconf.texi (Transforming Names): Equality between target
8437 and host is irrelevant.
8438 (Specifying Names, Canonicalizing): Remove all references to the
8439 backward compatibility hooks. Rather, collect them all into...
8440 (Hosts and Cross-Compilation): this new section.
8441 * doc/install.texi (System Type): Ditto.
8442 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8443 that `--host' implies cross-compilation.
8445 2002-03-04 Akim Demaille <akim@epita.fr>
8447 * doc/autoconf.texi (Evaluation Macros): New.
8448 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8449 useless.
8450 (_m4_foreach): Define the variant with immediate evaluation so
8451 that it contains exactly the items, not an expression which
8452 evaluation is the current item.
8453 (m4_re_string, m4_re_word): Don't over quote them.
8455 2002-03-04 Akim Demaille <akim@epita.fr>
8457 Instead of having stacking `shift's evaluated at the end, let
8458 `foreach' loops immediately evaluate them.
8460 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8461 $*. This is the n-th time I change my mind, but hopefully this is
8462 the last...
8463 (m4_lquote): New.
8464 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8465 efficient.
8466 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8467 it was only a hack for m4_text_wrap.
8468 (m4_car2): Remove, replaced by...
8469 (m4_cdr): New.
8470 (_m4_foreach): Adjust.
8471 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8472 m4_bpatsubst for clarification.
8474 2002-03-04 Akim Demaille <akim@epita.fr>

8558 not unsigned long.
8559 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8560 cross-compilers, too. This undoes some of the most recent change
8561 to this file.
8563 2002-02-05 Akim Demaille <akim@epita.fr>
8565 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

8582 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8583 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8585 2002-02-05 Akim Demaille <akim@epita.fr>
8587 * bin/autom4te.in (&parse_args): Implement `frozen files are
8588 optional are the sum of the previous files on the command line'.
8589 Also, pass `--reload-state=' on them, so...
8590 (handle_m4): don't.
8591 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8592 (M4sh): Rely on M4sugar.
8593 (Autotest, M4sh, M4sugar): Use frozen files.
8595 2002-01-31 Akim Demaille <akim@epita.fr>

8602 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8603 alphanumeric to `-' instead of `_'.
8605 2002-01-30 Akim Demaille <akim@epita.fr>
8607 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8608 for plain code, the other for cross-compilation code. The latter
8609 is now run with GCC only.

8622 so that aclocal 1.4 works.
8623 Reported by Alexandre Duret-Lutz and Larry Schmitt.

8627 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8628 needs an argument.
8630 2002-01-28 Akim Demaille <akim@epita.fr>
8632 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8633 AUTOTEST_PATH *after* it was set.
8634 Don't put `.' in the PATH: the user should be precise and `./' if
8635 needed. In addition, given that the test suite does some `cd', if
8636 `.' is in the path, the `tested programs' sections will report
8637 programs found in the test suite's directory, while during the
8638 tests (performed in their own directory), these programs are no
8639 longer visible. In other words, the results is confusing and
8640 useless.
8641 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8643 2002-01-24 Akim Demaille <akim@epita.fr>

8655 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be

8683 2002-01-21 Akim Demaille <akim@epita.fr>
8685 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8686 message on invalid options.
8687 * bin/autom4te.in (parse_args): Don't use
8688 Autoconf::General::getopt with non valid options.
8690 2002-01-17 Jim Meyering <meyering@lucent.com>
8692 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8693 $ac_cv_exeext so we don't use an old, invalid, cached value.
8695 2002-01-11 Akim Demaille <akim@epita.fr>

8707 package.m4, since is really depends upon configure.ac, not
8708 configure.
8709 * doc/autoconf.texi (testsuite Scripts): Adjust.
8710 * tests/Makefile.am (package.m4): New.
8711 EXTRA_DIST it since its a source.
8713 2002-01-06 Akim Demaille <akim@epita.fr>
8715 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8716 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8717 and PACKAGE_BUGREPORT from here...
8718 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8719 arguments.
8720 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8721 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8722 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8723 * tests/tools.at (autoheader): Adjust.
8724 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8726 2002-01-06 Akim Demaille <akim@epita.fr>

8745 2001-12-14 Akim Demaille <akim@epita.fr>
8747 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8748 trailing files, don't apply `-rf' to files which might not be
8749 created by configure (core, core.*, and *.core), but just `rm -f'.
8750 Suggested by Jonathan Kamens.
8752 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8754 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

8789 Remove $filepath, useless.
8790 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8791 variables, they are really part of the tokens.
8792 Split the input line on spaces and then look for tokens.
8793 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8794 because of `lex$U.$(OBJEXT)'.
8795 (&scan_files): Use "@list" instead of join.
8796 * doc/Makefile.am (CLEANFILES): Add *.fns.
8798 2001-11-26 Akim Demaille <akim@epita.fr>

8863 This patch implements a `long double' suggestion by Oliver Kiddle.
8865 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8866 static, to catch errors if the value isn't known at compile-time
8867 and the compiler supports dynamic arrays. Change its name from
8868 `_array_' to `test_array' to avoid potential name clashes.
8869 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8870 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8871 better than double. Catch a bug in GCC 2.95.2 x86.
8872 * doc/autoconf.texi (C Compiler): Document the above.
8873 * NEWS: Likewise.
8875 2001-11-13 Akim Demaille <akim@epita.fr>
8877 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8878 hand.
8879 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8881 2001-11-13 Akim Demaille <akim@epita.fr>
8883 * lib/autotest/general.m4 (AT_INIT): After having run the test
8884 group, go back to the initial directory, not to at_suite_dir.
8886 2001-11-13 Akim Demaille <akim@epita.fr>
8888 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8889 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8890 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8891 option.
8892 (AT_CHECK_CONFIGURE): Use absolute paths.
8893 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8894 The problem is still the old one: there is no means in M4 (that I
8895 know about) to create a defining macro, because there is no means
8896 to create `$1' etc., therefore, the defining macro ``swallows''
8897 all the arguments meant to the defined macro.
8899 2001-11-13 Akim Demaille <akim@epita.fr>
8901 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8902 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8903 configure.ac.
8904 * tests/aclocal.m4: Remove, as it is no longer used.
8906 2001-11-13 Akim Demaille <akim@epita.fr>
8908 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8909 variable names when referring to a single test group, or to
8910 `suite' when referring to the whole test suite.
8911 `at_last_test' is removed: m4 compute at_format itself.
8912 (at_stdout, at_stder1, at_stderr): New variables.
8913 (AT_CHECK): Use them.
8915 2001-11-13 Akim Demaille <akim@epita.fr>
8917 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8918 in PATH.
8919 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8920 Do it as soon as a test fails, don't wait till the end of the test
8921 suite.
8922 Don't remove $as_me.[0-9]*, since these files no longer exist.
8924 2001-11-13 Akim Demaille <akim@epita.fr>
8926 * tests/tools.at: Use absolute paths, since we are no longer run
8927 in place.
8929 2001-11-13 Akim Demaille <akim@epita.fr>
8931 Now that tests are running in their own private dir, there is no
8932 need to list the files to remove at the end of tests groups.
8934 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8935 (AT_data_files, at_data_files): Remove.
8936 (AT_CLEANUP, AT_DATA): Simplify.
8937 (AT_INIT): Adjust.
8938 Remove the group dir if !debug && !failed.
8939 * tests/atspecific.m4: Adjust.
8941 2001-11-13 Akim Demaille <akim@epita.fr>
8943 Start a new layout for Autotest: `testsuite' creates
8944 `testsuite.dir' in which the at-check-line etc. files are to be
8945 found, and `testsuite.dir/003' where the test group 3 is run.
8947 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8948 at_check_line_file, at_format, at_test_normalized, at_group_dir
8949 are new variables.
8950 Create the directories.
8951 Use absolute paths for at- files.
8952 (AT_CHECK): Adjust.
8954 2001-11-11 Michael Matz <matz@kde.org>
8956 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8957 (m4_car2): New.
8958 (m4_car): Properly quote arguments.
8960 2001-11-13 Akim Demaille <akim@epita.fr>
8962 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8963 with stricter rules on LIBOBJS.
8965 2001-11-12 Paul Eggert <eggert@twinsun.com>
8967 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8968 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8969 __PROTOTYPES too.
8971 2001-11-12 Akim Demaille <akim@epita.fr>
8973 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8975 2001-11-12 Akim Demaille <akim@epita.fr>
8977 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8978 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8979 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8980 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8981 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8982 specify to what the macro should be defined (typically to 1).
8984 2001-11-12 Akim Demaille <akim@epita.fr>
8986 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8987 From Jim Meyering.
8989 2001-11-12 Akim Demaille <akim@epita.fr>
8991 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8992 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8993 definition used by Automake where LEX is +/- "${missing} lex" and
8994 `missing' itself contains variables.
8996 2001-11-12 Akim Demaille <akim@epita.fr>
8998 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8999 Now that M4sh pushes BODY, the comments were output at the end of
9000 the test suites.
9002 2001-11-08 Akim Demaille <akim@epita.fr>
9004 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9005 that we can trace macros from aclocal.m4.
9006 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9007 obsoleted, and redirect to the former anyway.
9008 Reported by Ralf Corsepius.
9010 2001-11-08 Akim Demaille <akim@epita.fr>
9012 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9013 processed only if present.
9014 * tests/torture.at (Configuring subdirectories): Use autoreconf
9015 instead of successive calls to autoconf.
9016 Add a nonexistent subdirectory to exercise the patch above.
9017 Reported by Ralf Corsepius.
9019 2001-11-08 Kevin Ryde <user42@zip.com.au>
9021 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9022 doesn't accept .S files.
9024 2001-11-07 Akim Demaille <akim@epita.fr>
9026 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9027 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9028 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
9029 * bin/autom4te.in (warn_forbidden): New.
9030 (handle_output): Use it.
9031 Read m4_pattern_forbid with messages.
9033 2001-11-05 Akim Demaille <akim@epita.fr>
9035 * bin/autom4te.in (--normalize): Remove.
9036 * lib/autom4te.in: Adjust.
9038 2001-11-05 Akim Demaille <akim@epita.fr>
9040 * tests/Makefile.am (testsuite): Rename this target as...
9041 ($(TESTSUITE)): this.
9042 From Nicolas Joly.
9044 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9046 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9047 the --prefix option, also remove it's argument.
9049 2001-11-05 Akim Demaille <akim@epita.fr>
9051 * doc/autoconf.texi (testsuite Invocation): Update.
9052 (Writing testsuite.at): Update.
9054 2001-11-03 Akim Demaille <akim@epita.fr>
9056 * doc/autoconf.texi: s/@code/@command/ where appropriate.
9058 2001-11-03 Akim Demaille <akim@epita.fr>
9060 * lib/Autom4te/General.pm: (&catfile, &canonfile)
9061 (&file_name_is_absolute): New, wrappers around routines from
9062 File::Spec.
9063 Use and export them.
9064 (&find_configure_ac): Optionally take a directory where to look at.
9065 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
9066 the arguments.
9067 Default @ARGV to `.', not find_configure_ac.
9068 (&autoreconf): Argument is a directory.
9069 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
9070 * doc/autoconf.texi (autoreconf Invocation): Update.
9072 2001-11-03 Akim Demaille <akim@epita.fr>
9074 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9075 (@export_forward_subs): New.
9076 Add basename, dirname, and fileparse.
9077 (@EXPORT): Adjust.
9078 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9079 Don't look for aclocal flags if we already know aclocal is not
9080 used.
9081 Move aclocal.m4t only if it exists.
9082 Reported by Ezra Peisach.
9084 2001-11-03 Akim Demaille <akim@epita.fr>
9086 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9087 passed on command line, defaulting to ./configure.ac if present.
9088 (&maybe_autoreconf, File::Find): Remove, unused.
9089 (&autoreconf): If autoconf is not used, don't try to trace.
9091 2001-11-02 Akim Demaille <akim@epita.fr>
9093 * configure.ac: Bump to 2.52g.
9095 2001-11-02 Akim Demaille <akim@epita.fr>
9097 Version 2.52f.
9099 2001-11-02 Akim Demaille <akim@epita.fr>
9101 * config/config.guess, config/config.sub, doc/standards.texi:
9102 * config/lispdir.m4: Update from masters.
9103 * configure.ac: Bump to 2.52f.
9105 2001-11-02 Akim Demaille <akim@epita.fr>
9107 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9108 Don't run aclocal when aclocal.m4 is not from aclocal.
9109 From Ezra Peisach.
9110 Don't run libtoolize and gettextize if --install is not given.
9112 2001-11-01 Paul Eggert <eggert@twinsun.com>
9114 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9115 be invoked before _AS_LINENO_PREPARE.
9116 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9117 than character ranges.
9119 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9120 invoking AS_BASENAME. Set the locale variables to 'C' if
9121 possible, as POSIX requires this to get the traditional
9122 behavior.
9123 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9125 2001-10-31 Paul Eggert <eggert@twinsun.com>
9127 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9128 with {}, as that triggers a bug in Bash 2.05.
9130 (_AS_LINENO_PREPARE): Use Sed rather than
9131 Awk. Fix the sed prepass to work even if there are multiple
9132 instances of $LINENO on the same line. Do not substitute for
9133 other variables like $LINENOT. Do not check file dates; such a
9134 check is unreliable on sufficiently fast machines, and removing
9135 the check makes the code simpler and more reliable. Check for
9136 output and chmod failures.
9138 * doc/autoconf.texi (Special Shell Variables): Document
9139 the above.
9141 2001-10-31 Akim Demaille <akim@epita.fr>
9143 * tests/Makefile.am (atconfig): Remove this target, Automake
9144 handles it now.
9146 2001-10-31 Akim Demaille <akim@epita.fr>
9148 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9149 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9150 provided, while it is optional.
9151 * configure.ac: Adjust.
9153 2001-10-26 Paul Eggert <eggert@twinsun.com>
9155 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9156 lib/Autom4te/Struct.pm:
9157 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9158 with 5.005_02.
9160 * doc/autoconf.texi (Special Shell Variables): Document some
9161 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9163 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9164 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9165 eval $LINENO is not portable in practice.
9167 2001-10-24 Akim Demaille <akim@epita.fr>
9169 * lib/Autom4te/General.pm (backname): New.
9171 2001-10-24 Akim Demaille <akim@epita.fr>
9173 * m4/: Remove, merged into...
9174 * config/: here.
9176 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9178 * doc/autoconf.texi (Shellology): Mention the problems with bash
9179 2.05's use of ANSI quoting in its `set' builtin.
9181 2001-10-22 Paul Eggert <eggert@twinsun.com>
9183 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9184 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9185 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9186 POSIX decided to standardize on the int flavor of strerror_r.
9187 Always do char* test, as there's no reason not to.
9188 Assign to a char* var, to catch strerror_r that returns int*.
9190 * doc/autoconf.texi (Particular Functions):
9191 Document the above changes. Also, document the fact that
9192 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9194 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9196 2001-10-20 Akim Demaille <akim@epita.fr>
9198 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9199 the executable was missing from the log.
9201 2001-10-20 Akim Demaille <akim@epita.fr>
9203 * lib/Autom4te/General.pm (&update_file): If destination is
9204 unchanged, remove the source.
9205 (&up_to_date_p): Don't be verbose, be debug.
9206 * bin/autoreconf.in: No longer support --m4dir.
9207 (&autoreconf): Display the full path of the configure.ac we are
9208 studying.
9209 Trace it only once.
9210 Be sure to honor --force with gettextize.
9211 Always run aclocal.
9212 * doc/autoconf.texi: Adjust.
9214 2001-10-20 Akim Demaille <akim@epita.fr>
9216 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9217 Remove, dead.
9218 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9219 `intl' is already present, as it refuses unless --force.
9220 (&parse_args): Use -I, --include instead of the old Autoconf
9221 options.
9222 ($localdir, $autoconf_dir): Remove.
9223 (@include): New.
9224 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9226 2001-10-19 Jens Petersen <petersen@redhat.com>
9228 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
9229 * doc/autoconf.texi (Particular Programs): Likewise.
9231 2001-10-19 Akim Demaille <akim@epita.fr>
9233 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
9234 file in @configure_input@.
9235 Don't mention `automatically' in addition to `generated'.
9236 * tests/torture.at (#define header templates): Adjust.
9238 2001-10-19 Akim Demaille <akim@epita.fr>
9240 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9241 comment, explain how to install automatic mode selection.
9242 From Russ Allbery.
9244 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9246 * bin/autoreconf.in (autoreconf): Display the path to the
9247 configure.ac being studied.
9249 2001-10-18 Paul Eggert <eggert@twinsun.com>
9251 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9252 long, to work around a bug in the HP C compiler version HP92453-01
9253 B.11.11.23709.GP.
9255 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9256 (AS_BASENAME_EXPR): New macro.
9257 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9258 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9259 and fall back on 'sed' only if the other two fail. This makes
9260 AS_BASENAME act more like AS_DIRNAME.
9261 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9262 contains white space.
9263 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9264 Use AS_DIRNAME, since I think it's now DOS-friendly.
9265 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9266 Allow "dirname //FOO" to return either / or //, as POSIX allows
9267 either behavior.
9269 2001-10-10 Akim Demaille <akim@epita.fr>
9271 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9272 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9273 From Eric Sharkey.
9275 2001-10-10 Akim Demaille <akim@epita.fr>
9277 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9279 (_AS_ECHO_N): AS_REQUIREs it.
9281 2001-10-10 Akim Demaille <akim@epita.fr>
9283 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
9284 (AC_INCLUDES_DEFAULT): Move to...

9293 transition code.
9295 2001-10-08 Akim Demaille <akim@epita.fr>

9298 (&parse_args): Pass verbosity/debugging options to subtools when
9299 --debug, not when --verbose.
9300 * lib/autom4te.in (Autoreconf-preselections): New.
9301 (Autoconf): Use it.
9303 2001-10-08 Akim Demaille <akim@epita.fr>
9305 * bin/autoreconf.in (autoreconf): Run libtoolize when appropriate.
9307 2001-10-08 Akim Demaille <akim@epita.fr>
9309 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9310 * bin/autoreconf.in (autoreconf): Run gettextize when appropriate.

9314 * tests/tools.at (AT_CHECK_PERL_SYNTAX): Check autoreconf.
9315 (Syntax of the shell scripts): Don't.
9316 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
9317 bother with $force since...
9318 * lib/Autom4te/General.pm: does.
9320 2001-10-08 Akim Demaille <akim@epita.fr>
9322 * bin/autoreconf.in: Rewrite in Perl.
9323 * configure.ac: Adjust.
9324 * lib/Autom4te/General.pm (&up_to_date_p): New.
9325 * bin/autom4te.in (&up_to_date_p): Use it.
9326 Rename as...
9327 (&up_to_date): this.
9329 2001-10-08 Akim Demaille <akim@epita.fr>
9331 * lib/m4sugar/m4sugar.m4 (m4_case, m4_bmatch, m4_normalize)
9332 (m4_list_cmp): Use $0 to reinvoke yourself.
9333 (m4_patsubsts): New.
9334 (m4_strip, m4_version_unletter): Use it.
9335 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH): Likewise.

9377 * lib/emacs/autotest-mode.el (autotest-mode-map): New.
9378 (autotest-mode): Adjust.

9403 CONFIG_SHELL defaults to a shell that supports LINENO if available.
9405 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
9406 shell does not support LINENO, and if CONFIG_SHELL is unset or
9407 empty, and if we can find a shell that does support LINENO,
9408 then set CONFIG_SHELL to that shell and then re-execute
9409 ourselves with CONFIG_SHELL.
9411 2001-10-05 Paul Eggert <eggert@twinsun.com>
9413 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9414 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9415 build of $(TESTSUITE).
9417 2001-10-05 Akim Demaille <akim@epita.fr>

9456 compatibility with POSIX shells.

9485 Don't use nested parenthesization. This patch was originally
9486 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,

9495 Check for `expr' arithmetic overflow, and for compilation failure,
9496 and invoke a new argument $4 if either is discovered.
9497 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9498 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

9531 (AC_PROG_CPP requires AC_PROG_CC): here and...
9532 * tests/fortran.at (GNU Fortran 77): there.
9533 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9534 AC_TRY_RUN is about compilation, not shell commands.
9535 (Test Programs): AC_TRY_RUN works as used to be advertised.
9537 2001-09-27 Akim Demaille <akim@epita.fr>
9539 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9540 Raja R Harinath:
9541 Be sure to detect when $LINENO always returns the same value.
9542 Look for the original script, basename($0) is certainly not
9543 enough.
9544 Pass the CLI arguments to `$as_me.lineno'.
9546 2001-09-25 Akim Demaille <akim@epita.fr>
9548 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

9556 of --language now.
9558 2001-09-23 Akim Demaille <akim@epita.fr>
9560 * doc/autoconf.texi (Top): Wrap in @ifnottex.
9562 2001-09-23 Akim Demaille <akim@epita.fr>
9564 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
9565 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.

9572 Skip nonexistent dirs.
9573 * doc/autoconf.texi (Preset Output Variables): Document these
9574 variables.
9576 * lib/autotest/general.m4: Do not reset AT_victims.
9577 Don't compute at_srcdir nor at_top_srcdir.
9579 * tests/tools.at: Hence use top_srcdir.
9581 * tests/Makefile.am, tests/autoconf, tests/autoheader,
9582 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
9583 Remove.

9594 * doc/autoconf.texi (Common Shell Constructs): Rename as...
9595 (Programming in M4sh): this.

9646 `$LINENO' support replacement when not supported.
9647 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

9649 (via m4_require). Cosmetic only.
9650 * lib/autoconf/c.m4, lib/autoconf/general.m4,
9651 * lib/autoconf/programs.m4: Replace all the occurrences of
9652 `__oline__' with `$LINENO'.

9660 it works.
9662 2001-09-21 Akim Demaille <akim@epita.fr>
9664 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9665 Suggested by Jim Meyering.

9682 PATH_SEPARATOR.
9683 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9684 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9685 be used instead of ':'.
9686 * lib/autotest/general.m4: Replace occurrences of ':' in
9687 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9689 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9692 arguments. Fixed a typo.
9694 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9696 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

9710 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9711 already have $file). Set output files to binary mode (helps avoid
9712 CR issues on DOSish systems).
9714 2001-09-19 Akim Demaille <akim@epita.fr>
9716 * lib/autotest/general.m4: Englishoes.
9717 From Tim Van Holder and Alexey Mahotkin.
9719 2001-09-18 Paul Eggert <eggert@twinsun.com>
9721 * doc/autoconf.texi (Common Shell Constructs): New node,
9722 documenting AS_DIRNAME.
9723 (Limitations of Usual Tools): Refer to it when discussing dirname.
9724 Also, update discussion of POSIX standard to reflect latest draft.
9726 * lib/autoconf/c.m4:
9727 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9729 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9730 Do not pass a first argument with leading '-'
9731 to expr, by parenthesizing initial integers that might be negative.
9733 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9734 now merely checks whether it is an error to pass an argument
9735 to getpgrp.
9737 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9738 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9739 whether it is a (compile-time) error to pass an argument to
9740 getpgrp. This simpler test supports the revised documentation,
9741 and is all that AC_FUNC_GETPGRP's users really need.
9743 2001-09-18 Akim Demaille <akim@epita.fr>
9745 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9747 2001-09-18 Akim Demaille <akim@epita.fr>

9756 correctly.
9757 Add test for AS_BASENAME.
9758 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9759 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9760 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9761 * tests/base.at: Fixed the expected responses. The old ones were
9762 one line out...
9763 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9764 the documentation claims it should (and how it behaved in 2.13).
9766 2001-09-18 Akim Demaille <akim@epita.fr>
9768 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9769 the AC_CONFIG_COMMANDS invocation.

9773 No longer to be shipped.
9774 (version.in): Remove.

9776 * lib/autoconf/status.m4: Adjust.
9777 Use `m4_PACKAGE_STRING'.
9778 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9779 the only optional argument is the name of the test suite.
9780 Expect `package.m4' to define the package signature.
9781 * lib/autom4te.in (Autotest): Add `package.m4?'.
9782 * tests/Makefile.am (package.m4): New.
9783 * tests/suite.at: ifnames is a victim.
9785 2001-09-18 Akim Demaille <akim@epita.fr>
9787 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9788 AC_LIBSOURCE, AC_CONFIG_FILES.
9789 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9790 program version string doesn't match the package's.
9791 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9792 after `(cached)'.
9794 2001-09-17 Paul Eggert <eggert@twinsun.com>
9796 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9797 Allow expression to return any value that can fit into unsigned long
9798 (not int, as before). Check for output errors.
9800 2001-09-17 Bruno Haible <haible@ilog.fr>
9802 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9803 Always include <stdio.h> and <stdlib.h>. Evaluate
9804 the expression in an extra function before these includes. Call
9805 fprintf "%d" only after ensuring the argument is of type 'int'.

9810 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9811 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9812 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9813 when they don't exist.
9815 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9816 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9817 need it.
9819 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9820 version with the version used by fileutils 4.1, except use
9821 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9822 we don't need it.
9824 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9826 2001-09-13 Akim Demaille <akim@epita.fr>
9828 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
9829 _first_.

9834 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9940 2001-09-07 Akim Demaille <akim@epita.fr>
9942 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
9943 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
9944 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
9945 related variables into `at_package_*'.

9978 2001-09-05 Akim Demaille <akim@epita.fr>
9980 Be ready to handle filenames as stupid as `dnl.at', for if even
9981 the maintainer is dumb enough to do that...
9983 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9984 excellence in M4 quotation: consider `__file__' is active.
9986 And BTW, when invoking m4, pass the --include in the right order:
9987 the wrong one.
9989 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
9990 4m.

10017 New, extracted from main.
10018 Use IO::File wherever possible.
10019 (input.m4): Be constant, use -I instead of hard coding $tmp.
10020 Therefore be a quoted heredoc.
10021 Don't invoke `_au_disable', since ac was not loaded, but just
10022 `unm4.m4'.
10024 2001-08-31 Akim Demaille <akim@epita.fr>
10026 Version 2.52d.

10051 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10052 (testsuite Scripts): There is no such thing as `atconfig.in'.
10053 And actually one diagram is missing: test suite runtime.
10055 2001-08-31 Akim Demaille <akim@epita.fr>
10057 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10058 inverse order.
10060 2001-08-31 Akim Demaille <akim@epita.fr>
10062 * bin/autoupdate.in (@include): `installcheck' revealed the path
10063 to m4sugar was lacking!
10065 2001-08-31 Akim Demaille <akim@epita.fr>
10067 * man/Makefile.am (.x.1): We really have to pass
10068 autom4te_perllibdir.
10070 2001-08-31 Akim Demaille <akim@epita.fr>
10072 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
10073 debug scripts, in particular passing explicitly listed tests to
10074 run is stupid.
10076 2001-08-31 Akim Demaille <akim@epita.fr>
10078 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10079 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10080 Use directly autom4te, not autoconf.

10083 2001-08-31 Akim Demaille <akim@epita.fr>
10085 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

10094 * bin/autom4te.in (&parse_args): Die on unknown languages.
10095 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
10096 need for autoconf.
10097 Promote --include over --macrodir and other obsolete options.
10099 2001-08-31 Akim Demaille <akim@epita.fr>

10103 * bin/autom4te.in ($autoconf): Pass --force.
10104 `print $out' doesn't print `$_' but `$out'.
10105 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10106 (autoheader): Pass --force since the test suite goes too fast for
10107 the time stamps.
10108 Adjust to the new autoheader messages.
10110 2001-08-31 Akim Demaille <akim@epita.fr>
10112 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
10113 Check the completeness of the #template.

10122 Drop AC_MACRODIR dead for real.
10123 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10124 `autoheader: `config.hin' is created'.
10125 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10127 2001-08-31 Akim Demaille <akim@epita.fr>
10129 * bin/autoheader.in: Rewrite in Perl.
10130 * tests/autoheader: Adjust.
10132 2001-08-31 Akim Demaille <akim@epita.fr>
10134 * bin/autoconf.in (--include, -I): New option.
10135 Map --localdir, --autoconf-dir onto it.
10136 Forward autom4te's options instead of interpreting them.
10137 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10138 There is no such envvar since the inception of autom4te.cfg.
10139 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10140 * bin/autoupdate.in: Adjust, and perform more control.

10142 * tests/autoconf: Dittowise.
10144 2001-08-31 Akim Demaille <akim@epita.fr>
10146 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10147 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10148 optionally `FILE'.
10149 Use -e, not -f, since /dev/null for instance is OK.
10150 (&parse_args): Adjust.
10151 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10153 2001-08-31 Akim Demaille <akim@epita.fr>
10155 * configure.ac: Also find tested executables in bin.
10156 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10157 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10158 installed peer executables, only PATH is allowed to resolve it.
10159 Pass `autoconf_dir' via options, not via invisible envvars.
10160 * lib/Autom4te/General.pm (&find_peer): Remove.
10161 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10162 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10163 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10164 find the executables for it.
10165 * tests/Makefile.am: Major cleanup. Too lazy to document...
10166 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10167 We only need PERL.
10168 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10169 indeed related to running the test suite, while passing
10170 --autoconf-dir and others is related to running non installed
10171 Autoconf executables. So don't do that, leave it to...
10172 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10173 * tests/autoscan: New.
10174 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10175 refer to library files: rely on --language.
10177 2001-08-29 Akim Demaille <akim@epita.fr>
10179 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

10182 2001-08-29 Akim Demaille <akim@epita.fr>
10184 * doc/autoconf.texi: Strip the @nodes.
10185 Suggested by Paul Eggert.

10188 2001-08-29 Akim Demaille <akim@epita.fr>
10190 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10191 Suggested by Paul Eggert.
10193 2001-08-29 Akim Demaille <akim@epita.fr>
10195 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10196 download in a tmp dir.
10198 2001-08-29 Akim Demaille <akim@epita.fr>
10200 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

10212 * bin/autoconf.in: Simplify and adjust.
10213 * tests/Makefile.am (AUTOMAKE): Use --set.
10214 * tests/atlocal.in: Adjust.
10215 * BUGS: distcheck and check are weak.
10217 2001-08-29 Akim Demaille <akim@epita.fr>
10219 * lib/autotest/general.m4: Use
10220 foo=`(command) 2>/dev/null`
10221 not
10222 foo=`command` 2>/dev/null
10223 (at-devnull): Rename as...
10224 (AT-devnull): this.
10225 (--clean): Remove AT-* files too.
10226 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10227 Reported by Nicolas Joly.

10248 * Makefile.maint: Formatting changes.
10249 (do-po-update, po-update, cvs-update, update): New targets.

10259 2001-08-27 Akim Demaille <akim@epita.fr>
10261 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10262 Support `VAR=VAL' as arguments.
10263 Compute PATH _after_ the options processing, so that AUTOTEST_PATH

10266 2001-08-27 Akim Demaille <akim@epita.fr>
10268 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.

10733 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
10735 * tests/semantics.at (AC_C_BIGENDIAN): New test.
10737 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10739 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10740 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10741 * doc/autoconf.texi (C Compiler Characteristics): Update
10742 documentation for AC_C_BIGENDIAN.
10744 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10746 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10747 magic values from an object file when cross-compiling.
10748 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10750 2001-08-10 Akim Demaille <akim@epita.fr>
10752 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10753 effects.
10754 Suggested by Russ Allbery.
10756 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10758 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10759 current $prefix to the sub-configures.
10761 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10763 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10764 extension (needed on BeOS). Reported by Guido van Rossum.
10766 2001-08-09 Akim Demaille <akim@epita.fr>
10768 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10770 2001-08-07 Akim Demaille <akim@epita.fr>
10772 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10773 removed.
10774 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10775 No need to remove the files before and after the each test, before
10776 each test and at the end of the suite is enough.
10777 Display only the children `times', not the shell's.
10778 If the test failed or was skipped, at-times is not available.
10780 2001-08-07 Akim Demaille <akim@epita.fr>
10782 Always produce testsuite.log, including when there are no
10783 failures. This helps getting information on skipped tests, and
10784 duration of the tests. Err, implement the latter btw.
10786 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10787 Dump information on the first run of each test.
10788 (AT_CLEANUP): Create `at-times' containing the duration of the
10789 test group.
10791 2001-08-07 Akim Demaille <akim@epita.fr>
10793 The use of `dumpstat' revealed that `len' was used although it
10794 should not. m4_text_wrap was using it, but in the Autoconf world
10795 where it is legal. Hence (i) test M4sh in its own world, not
10796 Autoconf's, and (ii), ahem, fix the bug :)
10798 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10799 does not like `' instead of [].
10800 (AT_INIT): Forbid `^_?AT_'.
10801 And don't output such tokens.
10802 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10803 `script.as', and `autom4te.cache'.
10804 Remove `empty' and `macro' which are no longer used.
10805 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10806 * tests/m4sugar.at: Use it.
10807 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10809 2001-08-07 Akim Demaille <akim@epita.fr>
10811 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10813 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10815 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10817 2001-08-04 Akim Demaille <akim@epita.fr>
10819 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10820 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10821 AC_TRY_LINK.
10822 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10823 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10824 (AC_F77_MAIN): Likewise.
10826 2001-08-04 Akim Demaille <akim@epita.fr>
10828 Don't rely on M4sugar outputting the patterns in files, since we
10829 might process the output _without_ running m4, hence without these
10830 files.
10832 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10833 * bin/autom4te.in (@Request::includes): Remove, unused.
10834 (@Request::source): Rename as...
10835 (@Request::input): this.
10836 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10837 (&handle_output): Fetch the patterns from the traces.
10838 `$forbidden' and `$allowed' are constant: use m//o.
10839 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10840 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10842 2001-08-04 Akim Demaille <akim@epita.fr>
10844 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10845 autoconf', i.e., in addition to caching traces, cache the output.
10847 * bin/autom4te.in (Request::cache): Rename as...
10848 (Request::id): this.
10849 ($cache, $icache, $tcache, $ocache): New.
10850 (&handle_m4): Save M4 output in the cache instead of $tmp.
10851 (&handle_output): Adjust.
10852 (&up_to_date_p): Check that the output cache is up to date too.
10853 (top level): Run `&handle_m4' iff force or the cache is invalid.
10854 Run `&handle_output' if the output cache is more recent.
10856 2001-08-04 Akim Demaille <akim@epita.fr>
10858 * bin/autom4te.in ($force): New.
10859 (&parse_args, &print_usage): -f, --force is a new option.
10860 (&handle_output): CPP directives might have spaces after `#'.
10861 (&parse_args): The first file only can be frozen.
10863 2001-08-04 Akim Demaille <akim@epita.fr>
10865 Don't let autom4te compute the `include' traces several times:
10866 first check that the trace cache file is up to date, and then
10867 compare its timestamp with that of the output.
10869 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10870 the preamble. Don't require 5.005 as Autom4te::General does it,
10871 and better yet (use `use', not `require'!).
10872 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10873 Class::Struct as Autom4te::Struct.
10874 * lib/Autom4te/General.pm (File::stat): Use it.
10875 (&mtime): New, export it.
10876 * bin/autom4te.in: Use it.
10877 Declare `$req' is invalid if it is outdated.
10878 Don't declare it valid before saving it if something went wrong.
10880 2001-08-04 Akim Demaille <akim@epita.fr>
10882 Autom4te shall not encode Autoconf data, and preselecting traces
10883 must be proposed to the users.
10885 * bin/autom4te.in (@required_trace): Remove.
10886 (@preselect): New.
10887 (&parse_args, &print_usage): -p, --preselect is a new option.
10888 (&up_to_date_p): Adjust.
10889 * bin/autoconf.in: Preselect some Autoconf macros.
10891 2001-08-04 Akim Demaille <akim@epita.fr>
10893 * tests/tools.at (autoconf --trace: user macros): Check traces on
10894 macros invoked without arguments, and macros invoked with multiple
10895 lines arguments.
10897 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10899 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10900 arguments.
10902 2001-08-03 Akim Demaille <akim@epita.fr>
10904 * bin/autoconf.in ($@): Work around the usual sh bug.
10905 From Nicolas Joly.
10907 2001-08-03 Akim Demaille <akim@epita.fr>
10909 Clean up the handling of the M4 builtins tracing exception.
10911 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10912 trace requests.
10913 (@m4_builtins): Rename as...
10914 (@m4_builtin): this.
10915 (%m4_builtin_alternate_name): New.
10916 (&parse_args): Complete the trace requests with alternate names.
10917 (&handle_traces): Hence no longer do it here.
10918 (&trace_requests): Remove, unused.
10920 2001-08-03 Akim Demaille <akim@epita.fr>
10922 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10923 m4_if, and m4_wrap.
10925 2001-08-03 Akim Demaille <akim@epita.fr>
10927 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10928 (m4_divert_pop): Dump the whole diversion stack when a diversion
10929 mismatch happens.
10930 * bin/autom4te.in (&handle_output): Remember of the first
10931 occurrence of a possibly undefined macro, not the last.
10932 Complain about the possibly undefined macros in the same order as
10933 the appear in the output.
10934 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
10935 * tests/tools.at (autoconf: forbidden tokens, basic)
10936 (autoconf: forbidden tokens, exceptions): No longer sort
10937 autoconf's stderr, as it is now deterministic.
10938 Check that `dnl' is caught.
10940 2001-08-01 Akim Demaille <akim@epita.fr>
10942 * configure.ac: Bump to 2.52c.

10954 2001-08-01 Akim Demaille <akim@epita.fr>

10957 `die'.
10958 (&END): New.
10959 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
10960 `END', as `Autom4te::General::END' will be triggered.
10961 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
10962 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

11397 cross-language link tests can be performed successfully.
11398 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
11399 after $LIBS, for consistency; this should be the general rule since

11520 Automake), include the separator themselves.
11522 * acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
