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

22 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Likewise.
23 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
24 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
25 this.
27 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
29 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
30 problems with arg script text that doesn't end in newline, and

41 to last change.
43 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
45 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
46 --help' should mention that `--version' outputs configuration
47 settings. Report by Bruno Haible.
49 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
51 Fix test suite failures reported by Pierre in
52 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
53 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
54 the compiler created a file "b.out" when it didn't create anything
55 at all.
56 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
57 Discard stderr too, when invoking the test script.

70 leading white space from text. From Bruno Haible.
72 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
74 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
75 compiler complains about it, even if things works after the
76 complaint. Problem reported by Peter O'Gorman.
78 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
79 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
80 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
82 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
84 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
85 after -R regardless of host. Patrick Welche reports that this
86 fixes things on NetBSD 3.99.
88 * NEWS: Recommend M4 1.4.5.
89 * README: Likewise.
90 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
91 * tests/tools.at (autom4te cache): Update wording of diagnostic
92 to match M4 1.4.5.
94 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
96 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
97 under AC_C_VOLATILE.
98 (Volatile Objects): Be a little less skeptical about what
99 "volatile" means. Derived from thoughts by Ben Pfaff in
100 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
102 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
104 * doc/autoconf.texi: Fix some typos.
106 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
108 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
109 more globally, since the 2006-06-30 patch didn't suffice. Problem
110 reported by Keith Marshall. Also, don't bother with builddir2,
111 since it shouldn't be needed any more.
113 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
115 * doc/autoconf.texi (Generic compiler characteristics):
116 Document AC_COMPUTE_INT. Fix wrong statements on Default
117 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
119 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
120 (_AC_COMPUTE_INT): Add obsoletion warnings.
121 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
122 AC_COMPUTE_INT.
124 * NEWS: Document change.
126 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
128 * doc/autoconf.texi (Volatile Objects): New section.
130 * NEWS: Document previous change.
132 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
134 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
135 Require that long long int be at least 64 bits wide. C99 requires
136 this and enough programs depend on it so we should check for it.
137 Bruno Haible reports in
138 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
139 that long long int is 32 bits wide with some nonstandard compilers.
140 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
142 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
144 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
145 to a nonexistent file, so that we don't have to worry about
146 a local site configuration that doesn't use /usr/local.
147 Problem reported by Keith Marshall in
148 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
150 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
152 * doc/autoconf.texi: Be more consistent about using @acronym with
153 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
154 quite right (it talked about "OSF/Tru64", even though the
155 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
156 and it even mentioned "OSF 4"!) and at this point there's little
157 reason to talk about OSF any more, since it died in 1994.
158 (Specific Compiler Characteristics): Simplify example of
159 negative-size array.
160 (File Descriptors): Reorder to make the text flow better.
161 Remove joke about "appreciate the various levels"; I didn't get it.
162 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
163 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
164 (File Descriptors, Limitations of Usual Tools):
165 Tone down the advice against renaming or removing open files.
166 (Limitations of Usual Tools): Add a new section, on 'rm'.
168 2006-06-26 Stepan Kasal <kasal@ucw.cz>
170 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
171 -lXt in LIBS, idea from Karsten Hopp; this was due since
172 this change:
174 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
175 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
176 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
177 (which belong to Xt, not X itself). See Debian bug 327655.
179 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
181 * configure.ac (AC_INIT): Bump to 2.60a.
182 * NEWS: Update.
184 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
186 Version 2.60.
188 * configure.ac, NEWS: Update.
190 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
192 * config/texinfo.tex: Sync from upstream.
194 * bin/autom4te.in (handle_traces): Transform the `@S|@'
195 quadrigraph correctly in traces.
197 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
198 Fix typos.
200 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
201 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
202 not defined.
203 * doc/autoconf.texi (Changed Directory Variables): New node,
204 to document the whole `datarootdir' business a bit better.
205 * NEWS: Update.
206 * tests/torture.at (datarootdir workaround): Extend test.
207 Prompted by report by Alexandre Julliard.
209 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
211 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
212 when using default mode of IBM C 6 for AIX. Problem and two-line
213 fix reported by Larry Jones.
215 2006-06-22 Alexandre Julliard <julliard@winehq.org>
217 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
218 about literal '${datarootdir}' if a definition is found in the
219 output file.
221 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
223 * NEWS: Use "M4" rather than "m4" when appropriate.
224 Problem reported by Eric Blake.
225 * doc/autoconf.texi: Likewise.
226 Use @acronym around BSD, GCC, and GNU when appropriate.
227 (Why GNU M4): Renamed from "Why GNU m4".
228 (Redefined M4 Macros): Mention that Posix
229 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
230 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
231 to int.
233 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
235 * bin/autom4te.in (handle_output): Do not forbid the empty
236 pattern.
237 * tests/tools.at (autoconf: the empty token): New test.
239 2006-06-20 Stepan Kasal <kasal@ucw.cz>
241 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
242 calls, so that we do not care whether they are LIFO or FIFO;
243 in the m4_wrap, do not check which diversion is the topmost
244 one, just check that the stack is balanced at the end.
245 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
246 base diversion forever--pop the previous diversion before
247 opening the new one; consequently, remove the m4_wrap call.
248 * lib/autotest/general.m4 (AT_INIT): Likewise.
249 * tests/m4sugar.at: Do not use
250 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
252 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
253 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
255 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
256 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
257 Rework example of m4wrap token-pasting trouble so that it doesn't
258 care whether it's LIFO or FIFO.
259 Fix some "contrary to"s that are awkward in English.
261 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
263 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
264 to `yes' instead of `int$1_t' if the type is found, for more
265 consistent configure output (where $1 is the number of bits).
266 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
267 Suggested by Bruno Haible.
269 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
270 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
271 with system headers. Report by Bruno Haible.
273 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
275 * config/config.guess, config/config.sub: Sync from upstream.
277 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
278 in order to avoid picking up an older installed frozen m4sh.m4f.
279 Besides an outdated shell startup, this could have been created
280 by an earlier M4 version with incompatible frozen file format.
282 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
284 * README: Recommend m4 1.4.4 instead of 1.4.3..
285 * doc/autoconf.texi: Likewise.
286 (Special Chars in Names): Say that $(.FOO) is portable, as
287 suggested by Stepan Kasal.
288 (Installation Directory Variables, Build Directories):
289 (Automatic Remaking, Subdirectories, Fortran Compiler):
290 (Making testsuite Scripts, Defining Directories):
291 Quote variable usages better.
292 (Making testsuite Scripts): Add clean-local rule to makefile
293 snippet, by Eric Blake.
294 (Installation Directory Variables): Fix table item font.
295 Reword slightly to clarify. Generalize advice about
296 not using special characters to include all file-related
297 vars, not just VPATH.
298 (Special Chars in Variables): Warn about special characters in
299 $(srcdir) too.
300 (Assignments): Clarify default-value example as suggested by
301 Ralf Wildenhues in
302 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
303 (Special Shell Variables): Note leading ./ or ../, as suggested
304 by Eric Blake.
305 (Limitations of Builtins): Under cd, warn about CDPATH.
306 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
307 Ralf Wildenhues.
309 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
311 * doc/autoconf.texi (Configuration Actions): Remove duplicate
312 `@var', for texi2html.
313 (Systemology): Some more word wrapping, for DVI output.
314 (autom4te Invocation): The short option for `--melt' is `-M',
315 not `-m'.
317 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
319 * doc/autoconf.texi: More formatting and English tweaks,
320 many suggested by Ralf Wildenhues.
321 Reword to avoid "@code{...}'s" and the like, since it's ugly
322 with Emacs info mode. discontents -> woes.
323 Put a few "will"s back. time stamp -> timestamp.
324 side-effect -> side effect.
326 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
328 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
329 Warn about $@ not persisting. Problem reported by Julien Danjou in
330 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
331 (Special Chars in Names): Renamed from Leading _ in Macro Names.
332 Mention other special chars, too.
334 2006-06-14 Eric Blake <ebb9@byu.net>
336 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
338 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
340 * doc/autoconf.texi: Some systematic minor improvements, as
341 follows. Use "makefile" when talking about makefiles
342 generally (which might be named "makefile" or "Makefile" or even
343 "foo.mk"), "Makefile" when talking about a specific makefile
344 called "Makefile". This unclutters the text from weird quotes
345 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
346 values" rather than "@var{foo}s" and similar constructs containing
347 "}s". Use "Make rules" rather than "Makefile rules". Minor
348 English-language improvements. Change the prefix "sub-" to "sub"
349 and "re-" to "re".
350 Put blank lines around examples more consistently.
351 Avoid "rather" and "very" as intensifiers.
352 Avoid "will" as an auxiliary.
353 (Limitations of Make): Split this node into....
354 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
355 (Leading _ in Macro Names, Backslash-Newline-Newline):
356 (Backslash-Newline Comments, Long Lines in Makefiles):
357 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
358 (obj/ and Make, make -k Status, VPATH and Make):
359 (VPATH and Double-colon, $< in Explicit Rules):
360 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
361 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
362 New nodes, resulting from splitup of Limitations of Make.
363 All cross-references changed. Raise the top node from
364 a section to a chapter, and all subnodes accordingly.
365 Redo the introductory wording to match the new organization.
366 (Installation Directory Variables): Use an example that is
367 closer to what Autoconf actually does. Mention that VPATH's
368 value should not contain metacharacters or white space.
369 (Fortran Compiler): Fix a VPATH bug in an example.
370 (Leading _ in Macro Names): Mention that this problem is no longer
371 of practical concern.
372 (VPATH and Make): Reword the advice to make it clearer
373 that Autoconf and Automake support VPATH in non-GNU make, but
374 many packages have bugs in this area.
375 ($< in Explicit Rules): Refer to Build Directories rather
376 than using a (non-VPATH-safe) example.
377 (Automatic Rule Rewriting): Mention the sort of disaster that
378 can ensue with Solaris-style rule rewriting with VPATH.
380 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
382 * doc/install.texi (Compilers and Options): Weaken the
383 suggestion to use GNU make for VPATH builds.
385 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
386 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
388 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
389 in regular expression.
391 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
393 * doc/autoconf.texi (Installation Directory Variables):
394 Drop extra @samp from `@table @samp' item.
395 (Limitations of Usual Tools): Comment fix.
396 Do not nest @samp just to point to other table items.
397 (Writing testsuite.at) <AT_CHECK>: The second argument to
398 `@dvar' is already @samp'ed.
399 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
400 do not use @var in the second argument.
402 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
404 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
405 $as_shell.exe too. Problem reported by Andreas Buening in
406 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
408 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
410 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
411 `unused variable' compiler warning, for `-Wall -Werror'.
412 Reported by Jaap Haitsma in
413 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
415 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
417 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
418 case the compiler dumps core. Problem reported for
419 OpenServer 5.0.7 by Tim Rice in
420 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
421 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
422 Likewise.
424 2006-06-06 Tim Rice <tim@multitalents.net>.
426 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
427 "ERROR" only shows up in "make check" output if there is an
428 error.
430 2006-06-06 Eric Blake <ebb9@byu.net>
432 * tests/tools.at (automatically allowed tokens): Fix typo.
434 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
436 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
438 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
439 typically overflows on x86 CPUs, even though the C standard
440 requires otherwise.
442 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
444 * configure.ac (AC_INIT): Bump to 2.59e.
445 * NEWS: Update.
447 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
449 Version 2.59d.
451 * config/texinfo.tex: Sync from upstream.
453 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
454 seen, invoke libtoolize with `--ltdl' argument.
455 * lib/autom4te.in (Autoreconf-preselections): Adjust.
456 * NEWS: Update.
457 Suggested by Eric Blake.
459 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
461 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
462 reported by Ralf Wildenhues.
463 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
465 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

473 2006-06-05 Stepan Kasal <kasal@ucw.cz>
475 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
476 message issued by AC_REQUIRE.
477 * tests/m4sugar.at: Check m4_require's error message.
478 * tests/base.at: Check AC_REQUIRE's error message.
479 * tests/local.at (AT_CHECK_M4): New macro, almost identical
480 to...
481 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
482 AT_CHECK_M4.
483 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
484 `expout' as the last parameter.
485 * tests/tools.at: Adapt to the above change.
487 2006-06-04 Stepan Kasal <kasal@ucw.cz>
489 * doc/autoconf.texi (Limitations of Usual Tools): Correct
490 information about race-free implementations of mkdir.
492 2006-06-04 Eric Blake <ebb9@byu.net>
494 * bin/autoreconf.in (help): Document M4 environment variable.
495 * bin/autoconf.as (Usage): Likewise.
496 * bin/autom4te.in (help): Likewise.
497 * doc/autoconf.texi (autom4te Invocation): Likewise.
499 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
501 * NEWS: GNU make now recommended for VPATH builds.
502 Mention that some macros are now documented to be obsolescent.
503 * doc/autoconf.texi:
504 Prefer "current" to "modern" to describe
505 currently-used (albeit perhaps old-fashioned) hosts.
506 Mention which ancient features no longer need to be worried about.
507 setgid -> set-group-ID
508 setuid -> set-user-ID (these are the Posix terms)
509 Fix some misuses of "only".
510 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
511 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
512 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
513 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
514 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
515 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
516 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
517 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
518 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
519 Mention that these macros are obsolescent.
520 (Installation Directory Variables): shall -> should
521 (File Descriptors): Mention that 0, 1, 2 might get reopened.
522 Mention that it's now safe to use 3 and 4.
523 (Limitations of Usual Tools): cp -r is now specified by Posix.
524 Omit longwinded and obsolescent discussion of cp -f.
525 Modernize discussion of expr, ls.
526 (Limitations of Make): Modernize discussion of VPATH builds.
527 Mention $? as a workaround in some cases.
528 * doc/install.texi (Basic Installation):
529 Mention "./configure; make; make install" first. Be more
530 specific about why this file is generic. Remove unnecessary
531 parens. Remove misleading "only". Remove obsolete advice
532 about csh. Don't say "configure" takes awhile; say it
533 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
534 and CC=c99 rather than CC=c89, as these are blessed by current
535 Posix. Recommend GNU make if doing a VPATH build.
537 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
539 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
540 examples involving shell prompts.
542 2006-06-02 Stepan Kasal <kasal@ucw.cz>
543 and Paul Eggert <eggert@cs.ucla.edu>
545 * doc/autoconf.texi (Here-Documents): Add details about the
546 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
547 use "here-documents" instead of "here documents".
549 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
551 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
553 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
555 * doc/autoconf.texi (File System Conventions): Warn about ":"
556 anywhere in directory names.
558 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
560 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
561 about quoting the case statement, just in case.
562 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
563 was fixed in ksh93g; reported by Ralf Wildenhues.
565 2006-05-31 Stepan Kasal <kasal@ucw.cz>
567 * doc/autoconf.texi (System Services): Do not document
568 overriding EXEEXT via ac_cv_exeext=ext.
569 (Particular Programs) <AC_PROG_MKDIR_P>:
570 Document that ${MKDIR_P} understands --.
571 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
572 comment.
574 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
576 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
577 argument with leading hyphen. Problem reported by Paul Eggert.
579 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
581 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
582 about quoting ac_try: quote all of it, if any of it seems suspicious.
583 This means we don't have to worry about ${ or sed any more.
584 Also, double-quote the case statement, to work around misuses via
585 underquoting as reported by Ralf Wildenhues in
586 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
587 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
588 undocumented and dangerous macro.
589 Problem reported by Ralf Wildenhues in
590 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
592 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
594 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
595 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
596 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
598 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
600 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
601 since evidently some packages rely on the old, broken behavior.
602 Problem reported by Ralf Wildenhues in
603 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
604 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
605 pre-2006-05-26 definitions, but leave in the comments that
606 these macros are dangerous and should not be used.
607 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
608 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
609 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
610 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
611 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
613 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
615 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
616 the use of 'tr', since this is our only use of 'tr'.
618 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
619 and Paul Eggert <eggert@cs.ucla.edu>
621 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
622 Don't assume 'grep' works on long lines, since AIX grep doesn't.
624 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
626 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
627 the output file in the `${datarootdir}' test.
629 2005-05-28 Stepan Kasal <kasal@ucw.cz>
630 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
632 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
633 mention of `datarootdir' in the input file(s), but literal
634 `${datarootdir}' in the output file, and we haven't warned yet,
635 then warn as well: the user may have (erroneously) used
636 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
637 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
638 * tests/torture.at (datarootdir workaround): Extend this test.
639 * NEWS: Update.
641 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
642 and Paul Eggert <eggert@cs.ucla.edu>
644 * doc/autoconf.texi (autoheader Invocation): The first argument to
645 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
646 alternatives and clear up the language a bit.
648 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
650 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
651 ac_config_guess, ac_config_sub, ac_configure.
652 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
653 Fix typo that prevented an unnecessary space from being removed.
654 Problems reported by Ralf Wildenhues in:
655 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
657 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
659 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
660 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
661 Don't use the term "thread-safe" to talk about mkdir race
662 conditions, since the problem is more a process than a thread
663 issue. Problem reported by Stepan Kasal in:
664 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
665 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
666 the test for 'install' more closely. Look at MKDIR_P first.
667 Look in the PATH, and at /opt/sfw/bin.
668 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
669 Don't bother to try mkdir -p, since we already check mkdir --version;
670 just look at the version number. (There's no easy way to check
671 for race-free implementations.)
672 * tests/tools.at (autoconf: subdirectories): Adjust to above
673 changes, since MKDIR_P now might end in "/mkdir -p".
675 * doc/autoconf.texi (autoheader Invocation): Mention that the
676 first arg of AC_DEFINE_UNQUOTED must be a literal.
677 Problem reported by Ben Pfaff in
678 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
680 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
681 * doc/autoconf.texi (Special Chars in Variables): New section.
682 (Preset Output Variables): Warn about special chars in CPPFLAGS.
683 (Installation Directory Variables): Quote $(datadir) better.
684 (Limitations of Builtins): Describe some of eval's trickiness.
686 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
687 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
688 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
689 in front of every arg, not just trailing args. Quote apostrophes.
690 (_AC_EVAL_ECHO): New macro.
691 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
692 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
693 removed.
694 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
695 exposed by quoting of eval argument. Put the command on line line
696 so it logs better.
697 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
698 (_AC_PATH_X, AC_PATH_X): Quote more safely.
699 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
700 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
701 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
702 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
703 Use eval more safely.
704 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
705 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
706 to be replaced.
707 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
708 lines, exposed by quoting of eval argument.
710 2006-05-26 Stepan Kasal <kasal@ucw.cz>
711 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
713 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
714 initialization of `ac_cv_exeext', do not override it if it was
715 already set, unless it was set to `no', for compatibility with
716 Autoconf-2.13, and comment this.
717 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
718 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
719 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
720 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
721 Document that this test may be overridden by setting
722 `ac_cv_exeext'.
724 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
726 Revert these two patches:
728 2006-04-06 Eric Blake <ebb9@byu.net>
729 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
730 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
731 2006-04-01.
733 2006-04-01 Stepan Kasal <kasal@ucw.cz>
734 Clean up _AC_COMPILER_EXEEXT* macros.
735 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
736 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
737 ac_file to the name of the default output file and call
738 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
739 initial `rm' of the candidate files...
740 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
741 the same list in subsequent `rm' calls, and for the temporary
742 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
743 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
744 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
745 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
746 no longer needed) by libtool. Make it a cache check.
747 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
748 copied here by mistake.
749 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
750 _AC_COMPILER_EXEEXT.
751 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
752 _AC_COMPILER_OBJEXT directly.
753 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
755 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
757 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
758 Fix description of how the buggy `sed' works.
760 2006-05-25 Noah Misch <noah@cs.caltech.edu>
762 Sync from Automake:
764 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
765 ENOLCK. Only mention `make -j' when applicable. Only raise
766 fatal errors when `make -j' is involved. Improve error message.
768 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
770 * doc/autoconf.texi (Here-Documents): We now know more about
771 the variable expansion in here documents bug.
772 Thanks to Tim Rice and Stepan Kasal.
774 * doc/autoconf.texi (Making testsuite Scripts): Add an example
775 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
777 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
779 * tests/autotest.at (Multiline command from M4 expansion):
780 No failure to be expected if the shell quotes newlines in
781 commands in the `set -x' output. Report by Tim Rice.
782 * THANKS: Update.
784 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
786 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
787 expansion in the here-documents used by config.status, as that
788 runs afoul of the Korn shell version M-12/28/93d bug described in
789 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
790 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
791 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
793 2006-05-23 Jim Meyering <jim@meyering.net>
795 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
796 Fix typo introduced with 2006-04-02 change. It reversed the sense
797 of the test.
799 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
801 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
802 ac_dB slightly, to save bytes in the script.
803 Max out at 50 lines, rather than 96; this is more likely
804 (though not guaranteed) to avoid obscure 'sed' failures.
806 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
808 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
809 `tr -d -' as bad option argument. Work around this by deleting
810 an unrelated character.
811 Report by Tim Rice <tim@multitalents.net>.
813 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
814 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
815 Stepan Kasal <kasal@ucw.cz>
817 * doc/autoconf.texi (Particular Programs): Do not promise that
818 we always prefer the GNU version of the program, and that we
819 search according to PATH; both rules can have exceptions.
820 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
821 AC_PROG_SED. Move descriptions of limitations
822 to the Limitations of Usual Tools section.
823 (Limitations of Usual Tools) <sed>: Mention script length
824 limitations with Solaris /usr/ucb/sed.
825 <grep>: Fix wording for empty alternative. Mention that -c and
826 -l should not be combined, and that -E and -F should not be
827 combined.
829 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
830 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
832 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
833 limits in Solaris 8 /usr/ucb/sed by testing a long script.
835 2006-05-22 Stepan Kasal <kasal@ucw.cz>
837 * doc/autoconf.texi (Defining Symbols): Literal parameter of
838 AC_DEFINE is now passed to m4_pattern_allow.
839 * NEWS: Mention that; likewise for AC_SUBST.
840 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
841 the parameter to m4_pattern_allow.
842 * tests/tools.at: Add a check for that.
844 2006-05-22 Stepan Kasal <kasal@ucw.cz>
846 * lib/autoconf/status.m4: Fix typos.
848 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
850 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
851 only the files that this macro generates.
853 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
855 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
856 the HP-UX sed limitation of 99 commands, labels do not count.
857 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
858 in the comment.
859 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
861 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
863 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
864 Import the following fix from coreutils:
866 2006-01-13 Jim Meyering <jim@meyering.net>
868 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
869 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
870 not double-quote uses of that variable, to accommodate the rare
871 case in which getmntent is available in none of the libraries
872 checked. This happens at least on FreeBSD 5.0.
874 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
876 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
877 ac_config_guess, ac_config_sub, and ac_configure, since evidently
878 some other programs unwisely rely on these undocumented vars.
879 But put in warning comments about them.
880 Problem reported by Ralf Wildenhues in
881 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
882 * NEWS: Document that these variables are intended to go away.
884 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
886 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
887 and set the language to C++ (analogous to the equivalent Fortran
888 tests).
890 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
891 * doc/autoconf.texi (C++ Compiler): Document it.
892 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
893 * NEWS: Update.
895 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
897 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
898 that caused config.status to generate 100-command sed scripts; the
899 portable limit is 99.
901 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
903 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
904 variable `ac_d' instead of `d' to avoid infringing namespace.
905 Report by Ralf Menzel.
907 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
909 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
910 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
911 * tests/tools.at (autoconf: subdirectories): New test, taken from
912 the corresponding problem report by Ralf Wildenhues in:
913 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
915 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
916 Quote some uses of shell variables if they might suffer unexpected
917 globbing. This doesn't fix all instances of quoting problems that
918 I found, just the easy ones that look safe.
919 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
920 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
921 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
922 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
923 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
924 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
925 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
926 Likewise.
927 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
928 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
930 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
932 * bin/autoreconf.in ($help): Reword according to the manual.
933 Suggested by Olly Betts.
935 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
936 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
938 * bin/autoreconf.in: Pass the directory argument to
939 `require_configure_ac'. Fix comment.
940 * tests/torture.at (Configuring subdirectories): Expose this.
941 Reported by Olly Betts.
943 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
945 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
946 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
947 Automake as follows:
949 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
950 `$configure_in' instead of `configure.in', to preserve
951 directory component.
953 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
955 * config/config.guess, config/config.sub, config/texinfo.tex,
956 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
958 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
960 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
961 test for C99 conformance; (bool) 0.5 is an integer constant
962 expression, but (bool) -0.5 is not. Problem reported by Fedor
963 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
965 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
967 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
968 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
969 Warn about obsolete install-sh files. Remove stray sentence
970 fragment and fix cross reference.
971 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
972 install -d; this undoes the 2006-05-10 change.
973 (MKDIR_P): Mark with AN_MAKEVAR.
974 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
975 that we don't require $INSTALL to be thread-safe. Move comments
976 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
977 of AC_PROG_INSTALL. Output a message saying that we're checking
978 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
979 MKDIR_P instead of AC_SUBST.
980 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
981 Special magic for MKDIR_P, too.
982 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
983 a dnl.
984 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
986 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
988 Sync from Automake, as follows:
990 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
991 * config/install-sh: Initialize IFS, so field splitting isn't
992 turned off later.
993 * config/mkinstalldirs: Likewise.
994 * config/missing: Remove superfluous quotes. Replace all uses of
995 `[' by `test', for consistency, and for..
996 * config/missing (sed_minuso, sed_output): New variables.
997 (autom4te, help2man, makeinfo): Use them. Unifies detection of
998 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
999 Fixes `missing' to detect `--output' for help2man. Fixes
1000 PR automake/483. Report by Dennis J. Linse.
1001 (autom4te): Document in `missing --help'.
1003 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1005 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1006 * config/install-sh: Don't use 'path' to talk about file names,
1007 as per GNU coding standards. Close a race condition reported by Ralf
1008 Wildenhues and Stepan Kasal. There is still a race condition
1009 on hosts that predate Posix 1003.1-1992, but we can't help this.
1010 Don't mishandle weird characters like space on pre-Posix hosts.
1011 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1012 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1013 AC_PROG_MKDIR_P from AS_MKDIR_P.
1014 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1015 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1016 earlier editions are not (including Automake 1.8.3).
1017 Do not suggest mkinstalldirs for thread-safety.
1018 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1019 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1020 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1021 presence of special characters and race conditions.
1022 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1023 in Autoconf's name space.
1025 2006-05-10 Bruno Haible <bruno@clisp.org>
1026 and Paul Eggert <eggert@cs.ucla.edu>
1028 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1029 from Automake with minor changes.
1030 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1032 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1034 * config/install-sh: Update to Automake CVS version, as follows:
1035 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1036 * lib/install-sh: Simplify the expr implementation of dirname.
1037 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1038 * lib/install-sh: Handle --, and diagnose unknown options.
1040 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1042 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1043 `./autom4te' to create `./testsuite', since the `all' target
1044 will ensure its presence, but `installcheck' should not create
1045 the uninstalled wrappers.
1047 * tests/torture.at (Unusual Automake input files): Skip if we
1048 detect automake < 1.8.
1050 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1052 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1053 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1054 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1055 * NEWS: Update.
1057 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1059 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1060 munge (multiple) white space and other oddities.
1061 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1062 single quotes in variable assignment.
1063 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1064 and similar failures by adding multiple spaces, tabs, and other
1065 special characters.
1066 Report and different test suggested by Francesco Romani
1067 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1069 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1070 single quotes, we only need to search for single quotes; this
1071 both simplifies the search pattern, and makes us less
1072 susceptible to `echo' variations for arguments not containing
1073 single quotes.
1074 (_AC_ARG_VAR_VALIDATE): Likewise.
1076 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1078 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1079 `$*' and IFS concatenation issue with traditional shells and
1080 bash-2.04. Report by Seanster@Seanster.com.
1082 2006-05-03 Bruno Haible <bruno@clisp.org>
1084 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1085 precisely which Mac OS X versions have the od problem.
1087 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1089 * doc/autoconf.texi: Use @option systematically.
1091 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1092 and Bruno Haible <bruno@clisp.org>
1094 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1095 about 'od'.
1096 (Integer Overflow): Mention the special case of integer division
1097 overflow.
1099 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1101 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1102 traditional shells like the Solaris one that do not use the
1103 first IFS character for assembling `$*'.
1104 Prompted by a related report from autoconf_bug@nro.ca.
1106 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1107 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1109 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1110 Mention more problems with the -e option.
1112 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1114 * NEWS: Typo.
1115 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1117 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1118 in URLs to improve DVI formatted output (requires texinfo 4.6).
1119 (System Services, Systemology, Shellology): Likewise.
1120 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1121 output.
1123 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1124 continuous text.
1125 (Runtime): Fix macro argument names to match description:
1126 `action-if-found' -> `action-if-true' and similarly.
1127 (Obsolete Macros): Likewise.
1128 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1129 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1130 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1132 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1134 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1136 * ChangeLog: Typo.
1137 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1138 DVI output.
1140 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1143 /bin/sh set unsorted output.
1144 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
1145 * tests/local.at: Likewise.
1147 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
1149 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1150 (Integer Overflow, Null Pointers, Buffer Overruns):
1151 (Floating Point Portability, Exiting Portably): New sections.
1152 (Writing Test Programs): Fix some langauge. Recommend exiting
1153 with status 1, not merely nonzero. Clarify exit declaration.
1154 (Run Time): Move C exit status stuff to new Exiting Portably section.
1155 (Systemology): Mention Posix and levenez. Update v7 reference.
1156 (Portable Shell): Mention the Posix shell.
1158 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1160 * bin/autoconf.as (me): Replace by as_me.
1162 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1164 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1165 since as_me isn't set yet.
1167 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1169 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1170 a few minor bugs in this area.
1172 * doc/autoconf.texi (Programming in M4sh): Comment out the
1173 documentation of AS_BASENAME, for now.
1174 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1175 (Limitations of Builtins) <basename>: Do not refer to
1176 AS_BASENAME.
1177 * bin/autoconf.as (me): Don't use AS_BASENAME.
1178 (dir): Remove the unused variable.
1179 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1180 AS_DETECT_REQUIRED. All uses changed.
1181 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
1182 All uses changed.
1183 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1184 (AS_BASENAME): Use "basename --" to protect against leading "-".
1185 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1186 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1187 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1188 (_AS_DIRNAME_PREPARE): Likewise.
1189 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1190 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1191 (AS_DIRNAME): Use "dirname --".
1193 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1195 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1196 of "run time" and "run-time" changed to "runtime", for consistency.
1197 * lib/autoconf/fortran.m4: Likewise (in comment).
1198 * lib/autoconf/functions.m4: Likewise.
1199 * lib/autoconf/general.m4: Likewise.
1200 * lib/autoconf/headers.m4: Likewise.
1202 * doc/autoconf.texi (Run Time): Document the exit status situation
1203 with more accuracy and detail.
1205 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1207 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1208 Archive is not officially `GNU' any more. Update URL.
1209 (Defining Directories): Likewise
1210 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1212 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1214 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1215 newline from the `trap' code to finish `config.log'; the NetBSD
1216 /bin/sh resets the exit status after an empty command, as
1217 documented in doc/autoconf.texi.
1218 Reported by Dalibor Topic <robilad@kaffe.org>.
1220 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1222 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1223 Suggested by Bruno Haible.
1225 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1227 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1228 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1229 Instead, just list the shells that we know work.
1230 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1231 changed. Be more cautious about the _cv_ variable.
1232 * tests/tools.at (Syntax of the shell scripts): Check the
1233 _cv_ variable once, at first, to avoid an internal autoconf error
1234 when sh -n does not work.
1236 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1238 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1240 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1242 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1243 use ">&-" since we're only 99.999% sure that this is portable,
1244 and since the MinGW bug is fixed in a different way.
1245 * lib/autotest/general.m4 (AT_INIT): Likewise.
1247 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1249 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1250 before opening config.log, to avoid hitting a bug on MinGW.
1252 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1254 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1255 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1256 This works around a MinGW bug reported by Eric Paire.
1257 Make sure that all writes to the log file append to it,
1258 rather than possibly losing data.
1259 * lib/autotest/general.m4 (AT_INIT): Likewise.
1261 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1263 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1264 description.
1266 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1268 * NEWS: Update.
1270 * configure.ac (AC_INIT): Bump to 2.59d.
1272 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1274 Version 2.59c.
1276 * Makefile.maint (news-date-check): Do not require a leading `*'
1277 before the release date in NEWS.
1279 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1280 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1282 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1283 the instantiated file do not contain the string 'datarootdir'
1284 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1285 @mandir@, replace the reference '${datarootdir}' by the value.
1286 * tests/torture.at (datarootdir workaround): New test.
1287 * NEWS: Advertise this temporary fixup.
1288 Based on a patch by Bruno Haible, reported and analyzed by
1289 Paul Eggert and Noah Misch.
1291 2006-04-12 Eric Blake <ebb9@byu.net>
1293 * tests/autotest.at (Debugging a failed test): Fix comment.
1295 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1297 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1298 all the changes since 2006-04-07.
1300 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1302 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1303 succeeded, but `ln -s file dir' failed, take care to remove the
1304 leftover target before the next test, to prevent its spurious
1305 failure; also make sure `ln file dir' works before selecting it.
1306 Thanks to Keith Marshall for pointing this out.
1307 * THANKS: Update.
1309 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1310 assignments in `at_debug_args', so that we put them correctly
1311 in the `run' script.
1312 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1313 Reported by Eric Blake.
1315 2006-04-11 Eric Blake <ebb9@byu.net>
1317 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1318 top-level tests after micro-suite has been run. Used in...
1319 (Debugging a successful test, Debugging script and environment),
1320 (Debugging a failed test): ...these new tests. The first of these
1321 is fixed by...
1322 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1323 macro, split out from...
1324 (AT_INIT): ...here, so that using -d also generates a run script.
1325 Document that -d inhibits top-level logging.
1326 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1327 inhibits top-level logging; debug scripts are created.
1329 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1330 check.
1331 * tests/autotest.at (Empty test, Empty check): New test to check it.
1333 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1334 from gcc.
1336 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1338 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1339 the files if a problem appears. Make the empty *.at files
1340 read-only, too. Proposed by Ralf Wildenhues.
1342 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1344 * config/Makefile.am: Add comment to force updated Makefile.in.
1346 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1347 space only patch to this file, this patch causes the Makefile.in
1348 files that include freeze.mk to be updated, and thus have a
1349 newer time stamp again, which in turn makes a pristine CVS
1350 checkout have correct time stamps.
1352 * Makefile.maint (cvs-sv): New macro, to be used..
1353 (config.guess-url_prefix, config.sub-url_prefix)
1354 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1355 point to CVS text checkout of Gnulib files.
1356 (copyright-check): Bump current year.
1357 (announcement): Do not hard-wire `./announce-gen'.
1358 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1359 correctly.
1360 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1361 `chmod +x'.
1362 (wget_files): Update config.guess, config.sub, texinfo.tex by
1363 `wget-update', now that their URLs work again.
1365 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1367 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1368 Problem noted by Paul D. Smith.
1370 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1372 * doc/autoconf.texi: Remove unused words from word list.
1373 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1374 .x-sc_trailing_space: New files.
1376 * doc/standards.texi: Sync from gnulib.
1378 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1379 `LIBOBJDIR' as experimental.
1381 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1382 with a target directory; it's internally implemented as `cp'
1383 anyway, but since Autoconf advertises the possibility to use
1384 a target directory when LN_S is `ln -s', we need to find out.
1385 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1386 analyzed by Keith Marshall <keith.marshall@total.com>.
1388 * THANKS: Update.
1390 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1392 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1393 confdefs.h as-is. In general, if it has backslash-newline or the
1394 like, then it doesn't work either to sort or to remove empty
1395 lines.

1406 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1408 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1409 apostrophe within a single-quoted string, as this is the usual
1410 tradition and is easier to read than '"'"'. Don't rely on the
1411 shell treating "$/" like '$/'. Use a more-consistent indenting
1412 style for the trap.
1414 2006-04-09 Eric Blake <ebb9@byu.net>
1416 * tests/autotest.at (Backquote command substitution),
1417 (Multiline backquote command substitution): Remove mistaken
1418 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1419 applied...
1420 (Parenthetical command substitution, Multiline parenthetical
1421 command substitution): here.

1498 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1500 Revert the patch from 2006-04-01 and only improve
1501 _AS_DETECT_BETTER_SHELL:
1503 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1504 skip nonexistent directories.
1505 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1506 only shell candidates which exist.
1507 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1508 * lib/autotest/general.m4 (AT_INIT): No need to give three
1509 parameters to _AS_PATH_WALK.
1511 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1512 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1514 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1515 distinguish m4sugar macros.
1516 * tests/tools.at (autoupdating with aclocal and m4_include):
1517 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1518 test case by Noah Misch <noah@cs.caltech.edu>.
1520 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1522 Revert my change from 2006-03-17, in other words:
1523 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1524 and DUALCASE=1.
1525 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1526 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1527 it is set.
1529 2006-04-07 Eric Blake <ebb9@byu.net>
1531 * doc/autoconf.texi (Programming in M4sh): Document that
1532 AS_MKDIR_P exits the script on failure.
1533 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1535 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1537 * config/elisp-comp, config/install-sh, config/mdate-sh,
1538 config/missing, config/mkinstalldirs: Sync from Automake.

1554 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1556 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1557 whether `set' quotes correctly: redirect stderr of the tested
1558 `set', and use a subshell, for Ultrix; use `sed' instead of
1559 `grep' for zsh `set' which may write binary output; match only
1560 at the beginning of a line, to avoid false positives.
1561 In order to avoid false positives by unrelated variables with
1562 multiline content, put the dump algorithm in a subshell and
1563 unset all variables containing newlines (except some which are
1564 special to the shell). Warn about cache variables that are
1565 unset.
1567 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1569 * config/config.guess, config/config.sub, config/texinfo.tex:

1578 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1579 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1580 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1581 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1583 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1584 shell issue with double-quoted command substitutions of native
1585 commands.
1586 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
1587 Marshall.
1589 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

1606 * tests/Makefile.am (maintainer-check-posix):
1607 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1609 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1610 ac_config_<foo>s again, sometimes normalized, sometimes not.
1611 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1612 (AC_CONFIG_COMMANDS): Do not do so here.
1613 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1614 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1615 2005-07-25 rewrite. Noticed by Noah Misch.
1617 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1618 _AC_PRESERVE_HELP_ORDER, ...
1619 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1621 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1622 inside m4_expand_once; it is redundant.
1624 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1625 for --help from Cygnus `configure.'
1627 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

1634 * lib/autoconf/status.m4: Replace <space>''<tab> with
1635 <tab><space> where this makes sense.
1637 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)

1640 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1641 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1642 * doc/autoconf.texi (Help Formatting): New node.
1643 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1645 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1647 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1648 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1649 lib/autoconf/types.m4, lib/autotest/general.m4,
1650 tests/mktests.sh, tests/torture.at: White space cleanup:
1651 remove some SPACE before TAB, or add quoting ('' or @&t@).
1653 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1655 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1657 2006-04-05 Eric Blake <ebb9@byu.net>
1659 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1660 empty test suite works.
1661 * tests/autotest.at (Empty test suite): Remove xfail.
1663 2006-04-05 Noah Misch <noah@cs.caltech.edu>

1666 TAGS to ac_config_<foo>s.
1667 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1668 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1669 normalizing it, consistent it with previous releases.
1670 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1672 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1674 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1675 Use simplified args that Eric Blake originally suggested.
1677 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1679 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1680 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1681 Use 'comm' rather than N instances of grep; this also fixes a bug
1682 whereby substrings were incorrectly matched, causing us to not
1683 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1684 (exclude_list): Exclude empty macros.
1685 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

1690 Switch from grep to awk syntax.
1691 (ac_exclude_script): Renamed from ac_exclude_egrep.

1696 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
1697 a subdirectory subject to Cygnus `configure'.
1698 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
1700 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
1701 report request when we have no AC_PACKAGE_BUGREPORT.
1703 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1705 * THANKS: Update.

1722 (output): Emit AC_CONFIG_SUBDIRS as needed.
1723 * tests/autoscan.at (autoscan): Remove XFAIL.
1725 2006-04-03 Noah Misch <noah@cs.caltech.edu>
1727 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.

1731 * THANKS: Add myself.
1733 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1735 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
1736 to log, point to testsuite output tree.
1738 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
1740 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.

1766 Clean up _AC_COMPILER_EXEEXT* macros.
1768 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1769 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1770 ac_file to the name of the default output file and call
1771 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1772 initial `rm' of the candidate files...
1773 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1774 the same list in subsequent `rm' calls, and for the temporary
1775 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1776 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1777 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1778 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1779 no longer needed) by libtool. Make it a cache check.
1780 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1781 copied here by mistake.
1782 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1783 _AC_COMPILER_EXEEXT.
1784 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

2557 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2558 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2559 by the function rather than ignoring it.
2560 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2561 comparing its address. Intel's interprocedural optimization was
2562 outsmarting the old heuristic. Problem reported by

2580 Stepan Kasal <kasal@ucw.cz>
2582 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2583 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2584 make its content writable before removing it. Remove an errorneous
2585 comment from the end, where the logs of the failed tests are copied
2586 to the main log file.
2588 2005-09-27 Stepan Kasal <kasal@ucw.cz>

2595 problems if the testsuite were running too fast.
2597 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2599 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

2611 suggested by Ben Elliston. Handle weird characters correctly.
2613 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2615 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2616 calls, so that the final expansion of this macro is shorter.
2617 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2618 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2619 the cleanup there. Use AS_VAR_* macros, to be more general.
2620 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2622 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2624 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

2642 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2644 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2645 in the example. Reported by Bruno Haible.
2646 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2647 "if $undefined_var;" succeeds with my shell.
2649 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2650 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2651 but change the m4_divert_text to m4_divert_once.

2655 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):

2661 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2662 some evil values and relying on the fact that $* concatenates the
2663 parameters by the first character from IFS.
2665 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2666 Stepan Kasal <kasal@ucw.cz>
2668 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2669 first header appears, define AH_HEADER.
2670 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2671 Update limitations about when to call AC_CONFIG_HEADERS.
2672 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2673 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2674 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2675 ``Configuration Actions''; fix their index entries.
2677 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2678 options correctly. Process N-M as M-N if M is smaller than N.
2679 Process ranges correctly so that N-N will run only N.
2680 Sort and uniquify the tests that will be run. If there is more
2681 than one test, reinsert the banners for the tests.

2687 before passing the macro name to AH_TEMPLATE.
2689 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2690 now opens log after option processing; in particular, --version
2691 and --help do not touch config.log.

2704 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2705 Language cleanup.
2707 * doc/autoconf.texi (Defining Symbols, Changed Results):
2708 Prepend to LIBS, not append, in examples.
2710 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2712 When building in place, set srcdir="."; suggested by Tim Van Holder.
2714 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2715 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2716 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2717 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

2729 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2731 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2732 add "2>&1"; gzip 1.2.4 prints help on stderr.
2734 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2736 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2737 was pushdef'ed twice while popped only once. Push it only once.

2747 * Makefile.maint: Update from Bison.
2749 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2750 "<tab>" in comment, so that the point is understandable.
2752 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2754 Rewrite substantial part of lib/autoconf/status.m4.
2755 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2756 and CONFIG_COMMANDS are not processed in four separate loops.
2757 Instead, there is one main loop. This alows that the common code
2758 is expanded only once, thus config.status (and configure) is smaller.
2760 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2761 the AC_LIST_FILES and cousins macros are no longer used.
2763 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2764 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2765 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2766 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2767 contain the initialization, nor the for loop, nor the associated
2768 commands; all these go to ...
2769 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2770 _AC_OUTPUT_CONFIG_STATUS.
2771 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2772 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2773 (_AC_OUTPUT_FILE): The creation of the sed script ...
2774 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2775 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2776 _AC_OUTPUT_MAIN_LOOP.
2777 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2778 _AC_CONFIG_COMMANDS): Use ...
2779 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2780 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2781 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2782 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2783 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2784 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2785 ... new macros.
2786 (_AC_CONFIG_UNIQUE): Update.
2787 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2788 Replaced by this ...
2789 (_AC_LIST_TAGS): ... new common macro.
2790 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2791 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2792 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2793 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2794 this didn't belong to the `config commands' section.
2795 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2796 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2797 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2798 to the `config commands' section either.
2799 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2800 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2802 ... and many changes to the comments nearby.
2804 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2805 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2806 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2807 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2808 (#define header templates): The comment at the top of the generated
2809 header now includes the name(s) of the source file(s).
2811 Several unrelated small changes:
2813 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2814 parameter to AC_DIAGNOSE.
2815 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2816 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2817 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2818 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2819 with AU::AC_OUTPUT.
2820 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2821 in AC_OUTPUT doesn't double-quote it either.
2822 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2823 parameters.
2825 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2827 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2828 versions of Portland Group compiler produce single- and double-quoted
2829 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2830 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2832 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2834 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2835 This is a corrected version of yesterday's patch.
2837 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2839 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2840 path, too; insert a "===" to emphasize the line.

2843 ac_cv_build_alias to ac_build_alias.
2844 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2846 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2847 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2848 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2849 (AC_ARG_VAR): ... here.
2850 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2851 target_alias.
2853 Keep a list of all precious variables and process them with one simple
2854 for loop, instead of expanding all commands, or, OTOH, complicated
2855 processing of output of "set".
2856 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2857 variable names in new macro...
2858 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2859 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2860 a loop to assign all ac_env_* and ac_cv_env_* variables.
2861 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2862 to INIT_PREPARE.
2863 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2864 its value to shell variable ac_precious_vars and call
2865 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2866 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2867 _AC_ARG_VAR_VALIDATE.
2869 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2870 and the AC_SUBSTs ...
2871 (AC_INIT): ... here.
2873 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2874 the ac_subst_files section in config.log.
2876 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

2886 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
2887 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2888 They are generated by the Tru64 v5.1B shell.
2890 2005-07-05 Stepan Kasal <kasal@ucw.cz>
2892 Fix my changes from 2005-07-01; reported by Noah Misch.
2893 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2894 description, the macro now accepts only a single tag.
2895 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
2897 Fix cases when the varsions of Autoconf and Autotest don't match.
2898 Reported by Noah Misch.

2900 at_top_builddir, for compatibility with older autotest.
2901 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2902 is not set, use at_top_builddir, for compatibility with older
2903 versions of autoconf.
2905 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2907 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2908 Problem reported by Patrick Welche.
2910 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2912 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2913 sed substitution command, so that we allow | in program prefixes
2914 and program suffixes. (& is a problem anyway; we're not fixing
2915 that here.)
2916 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2917 configure_input, top_builddir, srcdir, etc.
2918 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2919 PATH_SEPARATOR in AUTOTEST_PATH.
2921 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2923 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
2924 for loop over config.site files using `set', to allow

2929 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2930 directories with weird names. Apparently some people like living

2951 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2952 document to output the default config_* lists to config.status.
2953 Don't recognize option --file, if the functionality is not there.
2954 Likewise for --header; moreover, recognize --he and --h as shortcuts
2955 for --help in that case.
2957 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2958 matches the order of execution. No code changed.

2979 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
2980 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2981 (AC_SUBST): Call it.
2982 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2983 the directory specific variables; but don't call it for configure_input.
2985 2005-06-28 Derek Price <derek@ximbiot.com>
2987 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2988 addition.
2990 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2992 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2993 directory have inherent problems with special characters like spaces,
2994 due to limitations in Make syntax. Problem reported by Alexandre
2995 Duret-Lutz.
2996 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

3009 from Justace Clutter.
3010 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
3011 variable into diagnostic. Make the diagnostic an error, not a warning,
3012 because we really don't support spaces and suchlike in dir names.
3013 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3014 Don't worry about backslashes in srcdir; it can't happen now.
3015 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
3016 Simplify ac_optarg handling.

3025 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3027 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3028 that '\|' is not allowed in BREs; recommend using newline separated
3029 list of patterns instead of multiple -e options.
3031 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
3033 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

3039 2005-06-21 Stepan Kasal <kasal@ucw.cz>
3041 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3042 b, t, r, w commands require single space, while : cannot have any.
3043 (Special Shell Variables): Fix sed code this in the example.
3044 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3045 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3047 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3048 expand to the empty list. Don't use two pairs of m4_changequote,
3049 it's not necessary.
3051 2005-06-20 Derek Price <derek@ximbiot.com>
3053 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
3055 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
3057 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3058 * doc/autoconf.texi:
3059 Don't mention Solaris versions so much, if a
3060 problem is common to all extant versions of Solaris. Say "SunOS
3061 4" instead of "SunOS" for SunOS 4.
3062 (awk): Mention more of the limitations of traditional Awk.
3063 (cat): Don't talk about cat -v.
3065 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

3073 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3074 on Mac OS X 10.4 reported by Peter O'Gorman in:

3076 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
3077 Use shell builtins rather than 'expr', to work around expr bug.
3079 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3081 * doc/autoconf.texi: "filesystem" -> "file system".
3082 "behaviour" -> "behavior".

3095 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
3096 quotes and backslashes. Patch from Derek Price.

3105 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3106 -u, since it outputs chatter if the input files are the same.
3107 Problem reported by Ralf Menzel.
3109 2005-06-08 Derek Price <derek@ximbiot.com>
3111 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3112 renaming them since they are about to be redefined anyhow.
3114 2005-06-08 Derek Price <derek@ximbiot.com>
3116 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3117 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3118 Move m4_undefine to alphabetical order.
3120 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3122 * README: Recommend GNU M4 1.4.3 or later.
3123 * doc/autoconf.texi (Introduction): Likewise.
3124 Reword to avoid some formatting glitches.
3125 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3126 Clarify explanation of HP compiler bug.
3127 Redo example output tp match current CVS snapshot.
3128 Use @example.org in email addresses when the examples
3129 might get inadvertently cut-and-pasted into user code.
3130 Remove example of autom4te usage that doesn't seem to work now.
3131 Use modern AC_INIT (except when the example is meant to be
3132 shown with Autoconf 2.13).
3133 Update ksh info for Solaris 9 and later.
3134 KB -> kB.
3135 Modernize description of Automake versions a bit.
3136 Don't claim a future version of Autoconf is near.

3142 follows its own advice about quoting better.
3143 Reword to avoid some formatting glitches.
3144 * doc/installt.exi: Reword to avoid some formatting glitches.
3146 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3147 Tru64 ksh pattern matching bug. Reported against Libtool by
3148 Albert Chin <libtool@mlists.thewrittenword.com> and
3149 Nicolas Joly <njoly@pasteur.fr>.
3151 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3153 m4_cdr of one-member list was [[]] (one-member list containing an
3154 empty string) instead of [] (an empty list. Callers were skewed to
3155 match this misbehaviour. As a consequence of this:
3156 - m4_foreach([x], [], [foo]) expanded to `foo', while
3157 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3158 This bug has been fixed:
3160 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3161 expand to an empty string; print error msg if called without
3162 an argument list.
3163 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3164 misbehaviour; handle [] and [[]] correctly.
3166 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3168 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
3169 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
3170 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
3172 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3174 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3175 swallow records with more than 99 fields.
3176 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3177 parse the long line.
3179 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3181 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3182 swallow literals longer than 399. Reported by Ralf Wildenhues.
3183 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
3184 to workaround this limitation.
3186 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3188 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3189 to gfortran, and make these the first two compiler names
3190 checked (following the general autoconf preference for gcc).
3192 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3194 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3195 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3196 (testsuite): Make sure autotest.m4f is up-to-date before using it.
3198 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
3200 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3201 expression of unbounded size when processing the --list
3202 option. This runs afoul of a limit of 399 bytes per regular
3203 expression on AIX. Problem reported by Ralf Wildenhues.
3205 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
3207 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
3208 * doc/autoconf.texi (Particular Headers): Reword example
3209 for multiline stdbool replacement.
3210 (Setting Output Variables): Reword text a bit. Don't
3211 give all the details about |#_!!_#|.
3212 Reword description of line replacement.
3214 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3216 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3217 now contain newlines, and substituted files must be referenced on
3218 a line alone; the sed scripts to substitute them are now very
3219 different.
3220 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3221 commands can be put in a sed script portably.
3222 * doc/autoconf.texi (Setting Output Variables): Document above
3223 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3224 use of multiline substitution.
3225 * tests/torture.at: No longer expect substitution of newline to fail.
3227 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
3229 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
3230 From Ralf Menzel (trivial change).
3232 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
3234 * tests/local.at: Don't attempt to check for negated character
3235 classes in shell scripts. The test was too brittle.
3237 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3239 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3240 * doc/autoconf.texi (Limitations of Builtins): Document this
3241 limitation.
3243 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3245 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3246 common code; used in many places in the tree.
3247 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
3248 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
3250 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
3252 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
3253 messages when ac_unique_file is not found.
3254 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3255 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3256 commands, for consistency with AC_MSG_ERROR and such.
3258 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3260 * bin/Makefile.am: Merge the two rules for creating scripts.
3262 2005-05-23 Stepan Kasal <kasal@ucw.cz>
3264 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
3265 obsolete; it was never documented.
3266 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
3268 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3270 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3271 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3272 (ac_top_builddir): ... this ...
3273 (ac_top_build_prefix): ... to this; the old name is also kept, for
3274 backward compatibility.
3275 (ac_top_builddir_sub): New variable, without the trailing slash,
3276 always nonempty.
3277 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3278 * doc/autoconf.texi (Configuration Actions): Rename
3279 ac_top_builddir to ac_top_build_prefix.
3280 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
3281 at_top_builddir to at_top_build_prefix.
3282 * lib/autotest/general.m4 (AT_INIT): Likewise.
3284 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3286 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
3287 of confdefs.h .
3289 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3291 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3292 argument to m4_foreach. I guess it was necessary in the past,
3293 but I think it's a no-op now.
3295 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3297 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3298 ``cat <<_ACEOF'' commands to one.
3299 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3300 * lib/autoconf/status.m4: On various places, use expr instead of
3301 ``echo|sed.''
3302 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3303 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3304 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3305 a range.
3306 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3307 the wrong patterns between ``case'' and ``esac.'' The previous
3308 code had false positives.
3310 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3312 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3313 as on 2005-05-02.
3314 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3315 Mention LIBOBJDIR.

3355 2005-05-13 Stepan Kasal <kasal@ucw.cz>
3357 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
3358 check.
3359 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3360 enough arguments, similarly as in m4_bpatsubsts.
3362 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3364 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
3365 of absolute paths.
3367 2005-05-11 Stepan Kasal <kasal@ucw.cz>
3369 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3370 for absolute directory names in one loop.
3371 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3372 abbreviations of --version and --debug.
3374 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3376 * doc/autoconf.texi (Autoconf Language): Be more precise about
3377 quoting rules. Problems noted by Stepan Kasal.
3378 Also, throughout this document, be more careful about white space.
3379 "blank", "white space", and "space" all have different meanings
3380 and we should be careful to say what we mean.
3382 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3384 Fix C++ related problems reported by Werner Lemberg.
3385 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3386 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3387 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3388 avoid problems with C++ and throw.
3389 * tests/compile.at: .cpp, not .cc.
3391 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3393 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3395 * doc/autoconf.texi (Generic Functions): Typos.
3397 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3399 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3400 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3401 set by latest automake.
3403 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3405 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3406 outputs 0 on GNU/Linux these days.
3408 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3410 * doc/autoconf.texi (Autoconf Language): Add more description
3411 about quoting heuristics.
3412 (Limitations of Builtins): Describe "set -" problems.
3414 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3416 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3417 not newline.
3419 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3420 by AC_DEFINE; it was a mistake.
3421 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3423 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3425 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3427 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3429 * doc/autoconf.texi (External Software): Quadrigraphs are not
3430 processed correctly in AS_HELP_STRING; avoid this in the examples.
3431 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3432 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3433 comment and reduce m4_default([foo], []) to [foo].
3434 (m4_strip): Update the explanation.
3436 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3438 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3439 Remove core.conftest.* too; it's generated by Tru64 5.1.
3440 Problem reported by Jennis Pruett.
3441 * lib/autoconf/functions.m4
3442 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3443 Don't bother to remove core files; AC_RUN_IFELSE should do that
3444 for you.
3446 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3448 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
3450 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
3452 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
3453 Report from Horst Wente.
3455 2005-04-15 Stepan Kasal <kasal@ucw.cz>
3457 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
3458 the comment.
3460 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3462 * doc/autoconf.texi (External Software, Package Options): Add
3463 examples showing how to implement --with-* and --enable-* options.
3465 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3467 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3468 as well as configure.in. Problem reported by Gregorio Guidi.
3470 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3472 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3473 pattern for alloca snippet.
3475 2005-04-04 Stepan Kasal <kasal@ucw.cz>
3477 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

3483 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3485 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3486 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3488 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3490 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3491 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3492 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3493 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3494 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3496 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3498 * NEWS: The configure command now warns you if you attempt to use
3499 a directory whose name contains a special character like space,
3500 newline, or "\".
3501 * doc/autoconf.texi (Installation Directory Variables): Allow
3502 "," in file names. Do not use \@; it's not a portable regexp.
3503 * bin/Makefile.am (edit): Likewise.
3504 * lib/Makefile.am (edit): Likewise.
3505 * tests/Makefile.am (edit): Likewise.
3506 * tests/semantics.at: Likewise.
3507 * tests/torture.at: Likewise.
3508 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3509 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3510 * doc/autoconf.texi (File System Conventions): Warn about
3511 unportable file names.
3512 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3513 (AC_INIT): Use it.
3514 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3515 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3516 ac_pwd, and quote srcdir.
3517 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3519 * doc/autoconf.texi: Fix some systematic formatting problems.
3520 ".)" needs a following @: if not at the end of a sentence, and
3521 similarly for "!)". "etc." should be preceded by a comma.
3522 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3524 2005-03-22 Bruno Haible <bruno@clisp.org>
3526 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3527 argument is often called 'build-aux'.
3529 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3531 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3532 macro AC_TRY_LINK is obsolete.
3533 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3534 `AC_CONFIG_FILES'.
3536 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3538 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3539 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3540 from a Common Lisp's `cl'.
3541 (AC_PROG_CXX): Behave according to the documentation: don't
3542 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3543 make the variable CCC precious; use `cl.exe', not `cl'.
3545 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3546 Alexandre Duret-Lutz <adl@gnu.org>
3548 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3549 /dev/null, as "configure" shouldn't read stdin, and this insulates
3550 us from problems (e.g., when testing for "cl"). Also, do this
3551 redirection before invoking "hostname" or "uname", and keep the
3552 original input stream available via...
3553 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3554 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3555 bother with "</dev/null" since it's now done at the top of
3556 'configure'.
3557 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3558 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3559 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3560 * doc/autoconf.texi (File Descriptor Macros): New section.
3561 (Printing Messages): Mention it.
3562 * tests/base.at (Input/Output): New test.
3564 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3566 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3567 newline if neither \c nor -n work, as that would output two
3568 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3570 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3572 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3573 This causes that any required macros inside will get before the if.
3574 * doc/autoconf.texi (autom4te.cache): A typo.
3576 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3578 Undo previous change, except keep the change to
3579 lib/autoconf/programs.m4 that replaced grep with shell
3580 pattern-matching. This is because net-snmp configure reads stdin.
3581 Reported by Noah Misch.
3583 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3585 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3586 from /dev/null, as "configure" shouldn't read stdin, and this
3587 insulates us from problems (e.g., when testing for "cl").
3588 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3589 before invoking "hostname" or "uname".
3590 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3591 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3592 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3593 "</dev/null" since it's now done at the top of 'configure'.
3594 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3595 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3596 Also, replace grep with shell pattern-matching, to save a process.
3598 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3600 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3601 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3602 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3603 compiler.
3605 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3607 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3608 grep -q isn't portable. Improve grep -s explanation.
3609 Problem reported by Dan Manthey.
3611 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3613 * doc/autoconf.texi (Special Shell Variables): Clarify
3614 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3616 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3618 * doc/autoconf.texi: Use @acronym for DJGPP.
3619 Fix some @code's that should have been @env's, and vice versa.
3620 Sort environment variable names.
3621 Mention that shells no longer inherit IFS.
3622 Don't recommend PATH_SEPARATOR=';' so strongly.
3623 Mention that $RANDOM might expand to the empty string.
3624 "symlink" and "soft link" -> "symbolic link".
3625 Improve mktemp description (reported by Bruno Haible).
3627 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3629 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.

3701 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3703 Try not to generated lines of unlimited length, as POSIX places a
3704 2047-byte limit on line length of portable text files.
3705 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):

3764 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3765 Update the long comment explaining it.
3767 m4_require no longer writes an ``is required by'' line to the
3768 execution stack. It contains only one bit of non-redundant
3769 information: that the macro was required, not called. And even
3770 this bit is useless in most situations: have you ever met a macro
3771 which both calls and requires the same macro?
3773 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3774 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3781 (_m4_require_call): Use it.
3782 * tests/m4sugar.at (m4_require): Expect output without the
3783 ``is required by'' messages.
3785 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3787 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3788 rather than x for expr.
3790 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3791 this is safe.
3792 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

3814 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3816 * doc/autoconf.texi (Limitations of Builtins): Clarify that

3819 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3821 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3822 Warn about newline stripping in `` and $(). Update Solaris
3823 version to 9.
3824 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3825 X insulates us from future changes to Posix.

3827 stripping.
3829 2005-01-19 Stepan Kasal <kasal@ucw.cz>

3851 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3853 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3875 (_m4_divert_n_stack): New macro; the expansion is
3876 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
3877 otherwise.
3878 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3879 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3880 stored in _m4_divert_diversion or _m4_divert_dump.
3881 (m4_divert_pop): When the parameter is given, compare the symbolic
3882 name with the last diversion pushed on the stack. Previously, the
3883 current diversion was compared with the numeric value of the
3884 diversion given as the parameter.
3885 (m4_require): If the macro hasn't been expanded yet, call ...
3886 (_m4_require_call): this new macro.

3919 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

3972 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
3973 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

4100 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):
4101 Don't depend on .x file explicitly, since "make" does that for us.
4102 Suggested by Stepan Kasal.
4104 * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.
4105 Add *.tmp.

4165 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
4167 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
4168 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
4169 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
4170 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
4172 2004-12-07 Stepan Kasal <kasal@ucw.cz>
4174 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

4189 with exactly one parameter.
4191 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4193 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4194 "char c = '\200';" rather than "char c = 0x80;" as the
4195 latter doesn't conform to the strict C standard due to
4196 overflow on signed char hosts.
4198 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4199 to -qlanglvl=ansi. We don't want to disable extensions.

4260 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
4261 the $1_found variable, don't test whether the file is executable;
4262 Both things are checked ...
4263 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
4264 the former ``test -f''.
4265 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
4267 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

4277 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
4279 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed

4300 Problem reported by Stepan Kasal.
4302 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
4304 Fix problems reported by Andreas Buening in:
4305 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html

4307 in test makefile.
4308 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
4309 readable; it's not true in OS/2-emx.
4311 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4313 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4314 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4315 (trivial change). Problem and patch reported by Andrew Church in:
4316 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4318 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

4345 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4346 texinfo.tex for now (done by hand now).
4347 * Makefile.maint (wget_files, cvs_files):
4348 Remove ansi2knr.c; nobody uses it.
4349 (ansi2knr.c-url_prefix): Remove.
4350 (cvs-update): Fix test for failure. I don't know why it ever
4351 worked...
4353 * doc/autoconf.texi: Update URLs, some of which went stale.
4354 Use @uref rather than @href.
4356 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4357 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4359 * config/config.guess, config/config.sub, config/elisp-comp,
4360 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4361 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4363 * NEWS, TODO, configure.ac, bin/autoscan.in,
4364 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4365 doc/install.texi, lib/Autom4te/Configure_ac.pm,

4369 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4370 tests/tools.at, tests/torture.at:
4371 Use "file name" rather than "filename" or "path",
4372 to be consistent with the terminology of the GNU coding standards.
4374 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4376 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4377 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4378 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4379 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4381 More fixes to support spaces in the name of the build directory.
4382 This isn't a complete fix but it's an improvement.
4384 * bin/autoconf.as (autom4te_options): New var.
4385 Use it instead of appending to AUTOM4TE, so that we can allow
4386 spaces in the build directory's absolute name.
4387 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4388 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

4399 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4401 * doc/autoconf.texi (Function Portability): Document isinf and
4402 and isnan. From a suggestion by Kevin Ryde.
4404 * lib/Autom4te/General.pm (END): Return correct exit status even
4405 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4407 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4409 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4410 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4411 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4413 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4415 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4416 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4417 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4418 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4419 * lib/autom4te.in (Automake-preselections): Preselect
4420 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4422 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4424 * lib/autom4te.in (Automake-preselections): Preselect
4425 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4426 trace them.
4428 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4430 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4431 Tru64.
4432 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4433 Document problem with "`""`" in pdksh POSIX mode.
4435 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4437 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4438 with pdksh, too. Problem reported by Patrick Welche via
4439 Gary V. Vaughan.
4440 * doc/autoconf.texi (Shellology): Note that set -o posix is
4441 useful for pkdsh, too.
4443 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4445 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4446 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4447 Don't fail if ENV or BASH_ENV is readonly.
4448 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4449 etc. are read only. Problem reported by Ludovic Courtes.
4451 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4453 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4454 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4455 (trivial change)
4457 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4459 * doc/autoconf.texi (File System Conventions): Warn about
4460 names like "aux". Problem reported by Eric Blake.
4462 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4463 by zero instead of array size, so that we can use any arithmetic
4464 constant expression (instead of requiring an integer constant
4465 expression). This allows us to test expressions like DBL_MAX <
4466 LDBL_MAX, which didn't conform to the C standard using the old
4467 method.
4468 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4469 now that we can do floating-point tests at compile time.
4471 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4473 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4474 and LDBL_EPSILON, as the resulting expression isn't an
4475 integer constant expression and violates the C standard.
4476 Problem reported by Nelson H. F. Beebe. Also, check
4477 for "L" suffix, and check that long double doesn't have
4478 worse range or precision than double, that mixed-mode
4479 arithmetic doesn't generate a diagnostic, that double
4480 constants fit in long double.
4482 2004-06-03 Kevin Ryde <user42@zip.com.au>
4484 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4485 malloc(0) and realloc(NULL,size).
4487 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4488 Bob Proulx.
4490 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4492 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4493 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4494 by Jim Meyering.
4496 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4498 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4499 can be rewritten using if-then-else. Suggested by Bruno Haible.
4501 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4503 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4504 Problem reported by Stepan Kasal.
4506 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4508 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4509 change). Patch reported by Ralf Wildenhues in
4510 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4512 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4513 function F exists if the compiler and linker let you compile an
4514 expression like (F != 0). Recent versions of GCC optimize away
4515 the reference to F in that case, since every function address must
4516 be nonzero, so the link succeeds even if F does not exist.
4517 Problem reported by Manu in
4518 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4520 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4521 "Unix". Many uses changed.
4522 (Limitations of Builtins): Explain better why the ! command isn't
4523 portable.
4525 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4527 * lib/autom4te.in (Automake-preselections): Preselect
4528 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4530 2004-05-19 Kevin Ryde <user42@zip.com.au>
4532 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4533 referencing AC_FUNC_STRERROR_R.
4535 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4536 note pessimistic assumption when cross compiling.
4538 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4540 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4541 (until 2004) invoked subcommands with sh -e, contra POSIX.
4542 Reported by Kevin Ryde.
4544 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4546 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4547 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4548 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4549 `test -f " /usr/bin/grep"', which _always_ failed.
4550 (AC_PROG_SED): Ditto bogus PATH fix.
4551 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4552 requires that grep correctly supports _multiple_ `-e' options, rather
4553 than stating only that grep should accept `-e'.
4555 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4557 Port to C99, which requires that 'exit' be declared.
4559 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4560 to ensure that stdlib.h is included.
4561 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4562 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4563 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4564 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4565 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4566 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4567 when using 'exit' in a test; C99 requires that 'exit' be declared.
4569 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4571 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4572 now prefers 'grep' implementations that accept -e.
4573 (Limitations of Usual Tools): Describe problems of traditional
4574 egrep and fgrep with long input lines, and of traditional grep
4575 with -e.
4576 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4577 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4578 All callers changed. Append /usr/xpg4/bin to the PATH, for
4579 Solaris.
4580 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4581 the user with complaints about multiple -e options.
4582 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4583 Define it with AC_PROG_GREP.
4584 * configure.ac (AC_PROG_GREP): Add.
4585 * lib/freeze.mk (GREP): New macro.
4587 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4589 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4590 a possible candidate only after all others fail, rather than
4591 consulting it first. This improves backward compatibility by
4592 better reflecting the way shell selection occurred in previous
4593 versions of Autoconf, and should help to avoid triggering latent
4594 problems in other packages, such as the one in Automake where zsh
4595 is not handled robustly:
4596 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4597 Although it is not Autoconf's responsibility to work around
4598 problems in Automake, it nevertheless makes sense to avoid
4599 introducing unnecessary incompatibilites.
4601 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4602 Gary V. Vaughan <gary@gnu.org>
4604 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4605 how deeply nested we are when a suitable tool is found, set the
4606 ac_path_TOOL_found flag.
4607 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4608 nested we are in this macro. Break out of all 3 nested loops if
4609 ac_path_TOOL_found is set.
4611 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4613 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4614 of the _AS_PATH_WALK loop too if GNU flavor is found.
4616 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4618 * doc/autoconf.texi (Limitations of Make): Update documentation
4619 for `$<'. New entry `Long lines', based on a report from Simon
4620 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4621 paragraph about DJGPP, based on a mail from Richard Dawe.
4623 2004-04-20 Paul Eggert <eggert@twinsun.com>
4625 * tests/c.at (C keywords): Don't assume that GCC supports
4626 "restrict" and "inline", as sufficiently-old GCC versions do not
4627 (also, GCC configured to be in pedantic C89 mode does not).
4628 Problem reported by Sumit Pandya in:
4629 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4631 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4632 consider -g to work if it generates warnings when plain compiles
4633 don't. Problem reported by Braden McDaniel in:
4634 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4636 * doc/autoconf.texi (Slashes): New section, to document a problem
4637 reported by Jim Meyering in:
4638 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4640 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4641 linker output files before linking, to work around IRIX 6 linker bug.
4642 Problem reported by Rainer Orth in:
4643 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4645 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4647 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4648 best tool so far counter rely on the tool path variable name to
4649 avoid checks for one tool being affected by the results of running
4650 the length check on a previous tool.
4652 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4653 match expression argument, as different greps have different
4654 regular expression flavours.
4655 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4656 literals.
4657 (AC_PROG_EGREP): Pass 'EGREP$'.
4658 (AC_PROG_GREP): Pass 'GREP$'.
4660 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4662 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4663 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4665 2004-03-29 Paul Eggert <eggert@twinsun.com>
4667 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4668 Types, Specific Compiler Characteristics, System Services,
4669 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4670 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4671 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4672 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4673 Likewise.
4674 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4675 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4676 AC_TYPE_OFF_T): Likewise.
4677 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4678 Likewise.
4680 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
4681 pacify libtool 1.5.2. Fix quoting problems in sed command.
4683 2004-03-28 Paul Eggert <eggert@twinsun.com>
4685 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4686 now defines HAVE_DECL_TZNAME if it is declared, when
4687 HAVE_STRUCT_TM_TM_ZONE is not defined.
4688 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4689 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4690 for HAVE_TZNAME.
4692 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4694 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4695 superfluous backslashing of quotes (") in sed expressions;
4696 thanks to Paul Eggert.
4698 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4700 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4701 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4702 H. F. Beebe for the bug report.
4704 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4706 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4707 quoted -cmdline argument in Portland Group compiler (bug
4708 reported by Jeffrey J. Barteet).
4710 2004-03-25 Kevin Ryde <user42@zip.com.au>
4712 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4713 (Run Time): ... here, where it's now mentioned.

4717 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4718 inherits from language Autoconf-without-aclocal-m4.
4719 (Customizing autom4te): Adjust example; the cache must now be
4720 disabled for language Autoconf-without-aclocal-m4.
4722 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
4723 Nathanael Nerode <neroden@twcny.rr.com>

4733 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
4734 AC_CHECK_TOOLS.
4735 (Specifying Names): Document the reason for these future
4736 behavioral changes.
4737 * tests/mktests.sh: Do not generate tests for the
4738 new macros.
4739 * NEWS: Document these changes.
4741 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4742 they make TeX hang up.

4746 * NEWS: New macro AC_CHECK_ALIGNOF.
4747 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4748 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4749 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4750 vowel.
4751 (AC_CHECK_ALIGNOF): New macro.
4752 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
4753 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
4754 those for sizeof.
4756 2004-03-03 Paul Eggert <eggert@twinsun.com>
4758 * bin/Makefile.am (edit): Don't use $< in a context where
4759 POSIX doesn't require support for it. Use $@.in instead.
4760 Problem reported by Anthony N. Frasso in
4761 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4762 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4764 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4766 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4767 from the next generation of Libtool.
4768 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4770 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4772 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4773 is not always thread-safe. Report from Nathanael Nerode.
4775 2004-02-18 Paul Eggert <eggert@twinsun.com>
4777 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4778 problem on QNX reported by Stephen Rasku in
4779 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4781 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4782 $(m4sh_m4f_dependencies); this removes a FIXME.
4783 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4784 (MAINTAINERCLEANFILES): Split into pieces,
4785 one per related section. Add $(srcdir)/wrapper.in.
4787 2004-02-09 Paul Eggert <eggert@twinsun.com>
4789 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4790 AC_SUBST provides no portable way to escape literal newlines.
4792 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4793 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4794 Darwin uses -lcrt2.o and there's little point to cataloging all
4795 the system variants. Partial fix reported by Andreas Waechter in:
4796 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4797 for bug reported by Nelson H. F. Beebe in:

4800 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
4802 * doc/autoconf.texi (AU_DEFUN): Fix English,
4803 suggested by Paul Eggert.
4804 * lib/autoconf/autoupdate.m4: Correct reference to
4805 acobsolete.m4, suggested by Alexandre Duret-Lutz.
4807 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

4810 refer to the correct file.
4811 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4812 the behavior of the third argument.
4813 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4814 correctly the behavior of the third argument. Document
4815 what the three macros that AU_DEFUN defines do. Fix
4816 warning message when the third argument includes $0
4817 (reported by Alexandre Duret-Lutz).
4819 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4820 Eric Sunshine <sunshine@sunshineco.com>
4821 Paul Eggert <eggert@twinsun.com>
4823 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4824 (AS_INIT): Output shell initialization there. Removed optional
4825 parameter. Expand _AS_SHELL_FN_SPY.
4826 (AS_INIT_WITH_SHELL_FN): Removed.
4827 (_AS_SHELL_FN_SPY): New macro.
4828 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4829 macros.
4830 (AS_SHELL_SANITIZE): Remove loop to find better shell
4831 and documentation for the parameter.
4832 (_AS_DETECT_BETTER_SHELL): Move it here.
4833 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
4834 (_AS_RUN): Move it here, support testing with eval.
4835 (AS_REQUIRE_SHELL_FN): Require shell functions when
4836 it is used.
4837 (_AS_LINENO_WORKS): Put around braces, we do not
4838 trigger the bash bug anymore.
4839 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4840 use AS_INIT_WITH_SHELL_FN.
4841 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4843 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4845 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

4860 * lib/autoconf/status.m4: Remove FIXME.
4861 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
4862 that the macro is not present anymore in the updated
4863 configure.ac.
4864 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
4865 of autoupdate.

4870 copyright years.
4871 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4872 2003 (except 1997) to the list of copyright years. This undoes
4873 the 2003-05-22 change, which removed the older years from the list.
4874 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4876 2004-01-27 Gary V. Vaughan <gary@gnu.org>

4882 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4883 AC_PROG_GREP.
4884 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4885 egrep and fgrep respectively if $GREP -E/-F don't work.
4886 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4887 _AC_PROG_GREP, and AC_PROG_SED.
4888 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4889 longest input length accepted by a command.
4890 (AC_PROG_SED): Use it.
4891 * doc/autoconf.texi (Particular Programs): Document the changes.
4892 * NEWS: Updated.
4894 2004-01-27 Paul Eggert <eggert@twinsun.com>

4901 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4902 bin/autoconf.in, config/Makefile.in, config/config.guess,

4916 sources.
4918 2004-01-26 Paul Eggert <eggert@twinsun.com>
4920 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4921 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4922 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4923 not <inttypes.h>. Problem reported by Tim Mooney in
4924 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4925 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4926 Likewise.
4928 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4929 otherwise "make check" fails because it forbids cmp (I guess
4930 because cmp treats files as binary on DOS-like systems).
4932 * tests/mktests.sh: Update copyright date to 2004, since some tests
4933 have changed in 2004.
4935 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4937 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4938 non-truncating sed or gsed program in PATH.
4939 * tests/acprograms.at: Add it.
4940 * doc/autoconf.texi (Particular Programs): Document it.
4941 * NEWS: Updated.
4943 2004-01-15 Paul Eggert <eggert@twinsun.com>
4945 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4946 -std1 disables some useful extensions on Tru64. Problem reported
4947 by N. Lichtmaier in
4948 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4950 2004-01-14 Paul Eggert <eggert@twinsun.com>
4952 * doc/autoconf.texi (Programming in M4sh): Document that
4953 AS_MKDIR_P succeeds if the destination is a symbolic link
4954 to an existing directory.
4955 (Limitations of Usual Tools): Note that mkdir -p might not
4956 succeed on symlinks to directories.
4958 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4960 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4961 * bin/autoheader.in: Grammar fix in message.
4962 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4963 Test for dir before calling mkdir -p. (trivial changes)
4965 2004-01-13 Eric Blake <ebb9@byu.net>
4967 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4968 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)

4974 2004-01-09 Paul Eggert <eggert@twinsun.com>
4976 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4977 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4978 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4979 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4980 AC_COMPILE_IFELSE, since we now assume our caller invokes
4981 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4982 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4983 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4984 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4986 2004-01-07 Paul Eggert <eggert@twinsun.com>
4988 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4989 `"'...'"`, as it's confusing (and I suspect it may not work on
4990 some platforms). The code was incorrect anyway, as it assumed
4991 that \$ evaluated to itself in that context. Reported by
4992 Alexandre Duret-Lutz.
4994 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

5046 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5047 -c -o might not work. From a suggestion by Kevin Ryde.
5048 (C Compiler, Generating Sources, Limitations
5049 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5050 Don't put '-o' after non-options, as POSIX doesn't allow this.

5103 _AS_LINENO_WORKS, use it to find out if shell
5104 functions work.
5105 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
5106 does not work.
5107 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

5122 them on the fly.
5124 2003-11-24 Akim Demaille <akim@epita.fr>
5126 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

5459 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5460 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5461 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5463 2003-09-26 Akim Demaille <akim@epita.fr>
5465 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5466 directory for AC_CONFIG_COMMANDS' first argument exists.
5467 This makes valid the invocation of _AC_SRCPATH that follows.
5468 Reported by Eric Sunshine.
5469 * doc/autoconf.texi (Configuration Commands): Adjust.
5471 2003-09-26 Akim Demaille <akim@epita.fr>
5473 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5474 Reported by Ralf Corsepius.
5476 2003-09-26 Akim Demaille <akim@epita.fr>
5478 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5479 arguments.
5480 Actually, use AU_ALIAS.
5481 From Bruno Haible.
5483 2003-09-26 Paul Eggert <eggert@twinsun.com>
5485 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
5486 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.

5492 The test suite are sometimes assigning timings incorrectly.
5493 Reported by Henk Krus.
5494 Diagnosed by Nicolas Joly.
5496 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5497 AT_help_all.
5498 Instead of making AT_help a sequence of assignments to grow
5499 $at_help_all, just make AT_help_all be the growing contents of
5500 $at_help_all, and make a single assignment in...
5501 (AT_INIT): here.
5502 (at_times_skip): Flip the meaning and rename as...
5503 (at_times_p): this.
5504 (AT_INIT): When summarizing the test that ran, remove
5505 $at_times_file after use, and check it is present before trying to
5506 use it.
5508 2003-09-25 Akim Demaille <akim@epita.fr>
5510 Version 2.57d.
5512 * bin/Makefile.am (edit): Handle '@configure_input@'.
5513 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5514 (ifnames): chmod -w.
5515 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5516 executables, not bin/ executables! Otherwise all the magic needed
5517 to find non installed files is turned off. This caused a failure
5518 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5519 as found in its environment (sent by tests/autoreconf): pointing
5520 to bin/autom4te that could not find its files.
5521 * tests/mktests.sh: Force the replacement of generated files, for
5522 the sake of "mv" program that are interactive when overwriting a
5523 -w file.
5524 * config/install-sh: Upgrade from CVS Automake.
5526 2003-09-23 Paul Eggert <eggert@twinsun.com>
5528 * doc/autoconf.texi (Limitations of Builtins): Document test -h
5529 versus test -L issues.
5531 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
5532 Paul Eggert <eggert@twinsun.com>
5534 Trivial change to support GCC's configuration procedure.
5535 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5536 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5537 about inconsistency if the preprocessor is set to give errors for
5538 any warning.
5539 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5541 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
5543 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
5544 and XFile.pm from Automake.

5555 from masters.
5557 2003-09-12 Akim Demaille <akim@epita.fr>
5559 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5560 not asm/types.h.
5562 2003-09-11 Akim Demaille <akim@epita.fr>
5564 * doc/autoconf.texi (Header Portability): linux/random.h.
5565 From Peter Hendrickson.
5567 2003-09-10 Akim Demaille <akim@epita.fr>
5569 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5570 willing to edit the output files.
5572 2003-09-10 Akim Demaille <akim@epita.fr>
5574 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5575 and AC_FC_FREEFORM.
5576 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5577 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
5579 2003-09-09 Akim Demaille <akim@epita.fr>
5581 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
5582 Reported by Gary Vaughan.
5583 * bin/autom4te.in (handle_m4): Likewise.
5585 2003-09-09 Akim Demaille <akim@epita.fr>
5587 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
5588 trailing files.
5590 2003-09-07 Paul Eggert <eggert@twinsun.com>
5592 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
5593 Improve the accuracy of the wording about obsolescence.
5594 From a suggestion by Ian Lance Taylor in
5595 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5597 2003-09-05 Paul Eggert <eggert@twinsun.com>
5599 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5600 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5602 2003-09-04 Akim Demaille <akim@epita.fr>
5604 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5605 AC_FUNC_WAIT3.
5607 2003-09-04 Akim Demaille <akim@epita.fr>
5609 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5610 (freeze): When exiting, use $exit_code.
5611 * lib/autoconf/fortran.m4: Comment changes.
5613 2003-09-04 Akim Demaille <akim@epita.fr>

5617 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5619 Add support for newer Fortran dialects. The F77 interface is
5620 unchanged, and continues to support Fortran 77. New FC macros
5621 correspond to all the old F77 macros, with output variables FC,
5622 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5623 available dialect, but older dialects can be specified. There are
5624 new macros AC_FC_SRCEXT to set the source extension, and
5625 AC_FC_FREEFORM to accept free-form source files.
5627 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5628 New macros.
5629 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

5644 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
5645 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5646 Rewrite in terms of the above.
5647 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5648 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
5649 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
5650 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.

5654 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5655 Document problems with timestamp resolution that 'make', 'cp -p', and
5656 'touch -r' have.
5658 2003-08-27 Akim Demaille <akim@epita.fr>
5660 * tests/m4sugar.at (cross_warning): Make sure to enable the
5661 output, so that we can track spurious m4sugar output.
5662 * tests/local.at: Require 2.57.
5663 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5664 are defaulted by AT_CHECK anyway.
5665 Use AT_CHECK_AUTOM4TE.
5666 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5667 missing dnl.
5669 2003-08-27 Akim Demaille <akim@epita.fr>
5671 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5672 when -Wobsolete is set.

5736 (&verbose): Remove.
5737 (&getopt): Adjust the note and verb channels, depending upon
5738 --verbose.

5740 * bin/autoupdate.in: Adjust.
5741 Use &verb, not &verbose.
5743 2003-08-21 Akim Demaille <akim@epita.fr>
5745 * bin/autoheader.in (&parse_args): Use &parse_warnings and
5746 &parse_WARNINGS.

5751 2003-08-21 Akim Demaille <akim@epita.fr>
5753 First stab at preserving warnings between calls to autom4te,
5754 including when the cache is used.
5756 There are still several issues: (i) there are too many runs of m4
5757 (one for include, one for warnings, and some more), (ii) warnings
5758 spreading on several lines are not handled gracefully, (iii) the
5759 code meant to have the call stack display for errors does not work
5760 (its handling should move from m4 to autom4te).
5762 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5763 Use them.
5764 (@preselect): Add m4_warn.
5765 ($exit_status): Remove, use $exit_code.
5766 ($help): Use Autom4te::ChannelDefs::usage.
5767 (&handle_m4): No longer define the m4_warnings.
5768 At each run, extract and report the warnings.
5769 Always cache the result, including if the exit status is on
5770 failure, since if nothing changes, we should result in the same
5771 failure, hence we can use the cache.
5772 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5773 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5774 Remove.
5775 (m4_warn): Redefine as a do-nothing: it is its invocation that
5776 matters, as warnings are now reported via traces.
5777 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5778 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5779 the latter reveals calls to the former.
5781 Adjust the tests.
5783 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5785 2003-08-21 Akim Demaille <akim@epita.fr>
5787 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5788 Use them.
5790 2003-08-21 Akim Demaille <akim@epita.fr>
5792 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5793 forward order.
5794 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5795 (&parse_warnings): Accept a list of warning requests.
5796 (&usage): Return a string, not a side effect.
5797 (cross): New warning category.
5799 2003-08-21 Akim Demaille <akim@epita.fr>
5801 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5802 (&require_configure_ac): Accept an optional directory argument.
5803 ($configure_ac): Remove.
5804 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5805 (&catfile): Remove.
5806 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5807 * bin/autoscan.in: Adjust.
5809 2003-08-20 Akim Demaille <akim@epita.fr>
5811 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5812 Reported by Alexandre Duret-Lutz.
5814 2003-08-20 Akim Demaille <akim@epita.fr>
5816 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5817 * bin/autom4te: Adjust.
5818 In particular, be Autoconf tools are really silent when properly
5819 working, bind the verbosity of the 'note' channel to $verbose.
5820 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5821 (&xsystem, &contents): Remove, since they are exported by...
5822 * lib/Autom4te/FileUtils.pm: this.
5823 More perldoc.
5824 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5825 * lib/Autom4te/FileUtils.pm: here.
5827 2003-08-20 Akim Demaille <akim@epita.fr>
5829 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5830 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

5882 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5883 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5884 shorter column three. Add DESCRIPTION to log file content.
5886 2003-08-13 Derek Price <derek@ximbiot.com>
5888 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

5931 Depend on Makefile since it contains substitutions.
5932 From Paolo Bonzini.
5933 * lib/autom4te.in (args): Add local.at? for Autotest args.
5934 This change was made on autom4te.cfg which is generated.
5935 Reported by Raja R. Harinath.
5937 2003-06-25 Akim Demaille <akim@epita.fr>
5939 * doc/autoconf.texi (Header Portability): sys/mount.h.
5940 From Gareth McCaughan.
5942 2003-06-23 Akim Demaille <akim@epita.fr>
5944 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5945 not all of them. This fixes 1. the fact that when testing
5946 Autoconf there are many many config.log, 2. the incorrect use of
5947 top_srcdir to find config.log.
5948 Don't mix the detailed output of failed test with the summary of
5949 failures. Rather, append detailed log afterwards.
5951 2003-06-23 Akim Demaille <akim@epita.fr>
5953 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5954 always run: output config.log on $at_group_log.
5956 2003-06-23 Akim Demaille <akim@epita.fr>
5958 * tests/torture.at (#define header templates): Don't use quotes in
5959 C++ comments as it puzzles Emacs' sh font-lock-mode.
5961 2003-06-23 Akim Demaille <akim@epita.fr>
5963 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5964 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5965 * tests/atspecific.m4: Rename as...
5966 * tests/local.at: This.
5967 * tests/suite.at: Move the globals into...
5968 * tests/local.at: here.
5969 * tests/Makefile.am: Adjust.
5970 * doc/autoconf.texi (testsuite Scripts): Adjust.
5972 2003-06-21 Kevin Ryde <user42@zip.com.au>
5974 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5975 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5976 ensuring we add -std1 for full-ANSI.
5978 * doc/autoconf.texi (hdrindex): New macro.
5979 Add index entries for portability of various standard header files.
5981 2003-06-20 Akim Demaille <akim@epita.fr>
5983 * configure.ac: Bump to 2.57b.
5985 2003-06-20 Akim Demaille <akim@epita.fr>
5987 Version 2.57a.
5989 2003-06-20 Akim Demaille <akim@epita.fr>
5991 * bin/autom4te.in: Don't rely on $HOME being defined.
5992 Reported by Marc Espie as PR/233.
5994 2003-06-20 Akim Demaille <akim@epita.fr>
5996 * lib/autotest/general.m4: Use at_times_file only if used.
5997 From Nicolas Joly.
5999 2003-06-20 Akim Demaille <akim@epita.fr>
6001 * config/config.guess, config/config.sub, config/elisp-comp,
6002 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
6003 Update from masters.
6005 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6007 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6008 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6009 (TEST_SCRIPT): New diversion.
6010 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6011 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6012 (AT_INIT): Support for expected failures.
6014 2003-06-02 Akim Demaille <akim@epita.fr>
6016 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6017 changes.
6018 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6019 Autoconf nor Automake.
6020 (&contents): New, from Automake.
6021 PODify.
6023 2003-05-28 Paul Eggert <eggert@twinsun.com>
6025 * NEWS, doc/autoconf.texi (Particular Functions),
6026 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6027 is the inverse of localtime.
6029 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6031 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6032 (handle_exec_errors): New function. Work around $! being
6033 altered by WEXITSTATUS.
6034 (xqx, xsystem): Use handle_exec_errors.
6036 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6038 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6039 Do not call `_exit()', simply modify `$?'.
6040 (xsystem): Reset $! before running system, and check it afterward.
6041 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6042 63 for version mismatches.
6044 2003-05-23 Akim Demaille <akim@epita.fr>
6046 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6047 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6048 the middle of a line).
6049 * lib/m4sugar/m4sugar.m4: Likewise.
6050 Remove useless spaces in comments.
6052 2003-05-23 Akim Demaille <akim@epita.fr>
6054 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6055 exit 63, so that we (or Automake's "missing") can tell the
6056 difference with a plain failure.
6057 * doc/autoconf.texi (Notices): Adjust.
6059 2003-05-23 Akim Demaille <akim@epita.fr>
6061 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6062 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6063 White spaces cleanup.
6065 2003-05-22 Jim Meyering <jim@meyering.net>
6066 Paul Eggert <eggert@twinsun.com>
6068 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6069 Remove `#include <stdlib.h>' from the list; we should never
6070 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6071 resulting namespace pollution would cause other tests to fail.
6072 Configure scripts run with some older versions of g++ and HP's
6073 aCC would fail due to such an #include. Problems reported by
6074 Matthew Mueller in <http://bugs.debian.org/120704> and by
6075 Keith Bostic in
6076 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6077 In the test, use the test declaration before including <stdlib.h>,
6078 as that's closer to how it'll be used.
6080 2003-05-23 Akim Demaille <akim@epita.fr>
6082 * doc/autoconf.texi (Header Portability): ucred.h.
6083 From Ian Redfern.
6085 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6087 Overhaul Autotest's logging: generate separate log files
6088 in testsuite.dir/NNN/testsuite.log, and append them to
6089 testsuite.log instead of re-running the test verbosely.
6091 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6092 file descriptor, write 0 to at_status_file instead of setting
6093 at_status=0, initialize some new variables (at_status_file,
6094 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6095 to rerun the tests, instead append the at_group_log to the
6096 at_suite_log when a test fails.
6097 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6098 with the AS_MESSAGE_LOG_FD redirected to stdout.
6099 (AT_CLEANUP): save the output status in $at_status_file
6100 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6101 its original place.
6102 (AT_CHECK): since tests are run with a redirected stdout,
6103 and used to be re-run in verbose mode, turn some $at_verbose
6104 into echo, and don't redirect the output of testing stdout
6105 and stderr.
6107 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6108 the name of the debugging directory and information about
6109 its contents.
6111 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6113 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6114 parameter.
6116 2003-05-22 Akim Demaille <akim@epita.fr>
6118 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

6180 2003-05-17 Akim Demaille <akim@epita.fr>
6182 * lib/autoconf/functions.m4: Use the default includes so that
6183 memcmp be declared before being tested.
6184 Reported by Sander Niemeijer.
6185 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
6186 * doc/autoconf.texi (Default Includes): Document
6187 AC_INCLUDES_DEFAULT.
6189 2003-05-17 Akim Demaille <akim@epita.fr>
6191 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
6192 * doc/autoconf.texi (Obsolete Macros): Adjust.
6193 Reported by Werner LEMBERG and Debian Bug 190886.
6195 2003-05-16 Akim Demaille <akim@epita.fr>

6226 and truncate.
6228 2003-05-06 Akim Demaille <akim@epita.fr>
6230 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6231 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6232 by aclocal.m4 is changed it might require the importing of another
6233 m4 extension file, i.e., aclocal must be run.
6235 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6236 (&parse_args): Use --force with aclocal if required and supported.
6237 (&autoreconf_current_directory): Use &run_aclocal.

6243 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
6244 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6245 argument instead of a file name, so that the request file remains
6246 open during the whole autom4te run.
6247 ($icache_file): New.
6248 (&freeze): Lock the $icache_file.
6250 2003-04-29 Derek Price <derek@ximbiot.com>
6252 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6253 seperator with m4_append_uniq(). It doesn't work.
6254 (AT_CLEANUP): Add `;' to end of at_help_all.
6255 (AT_INIT): Allow --keywords to be specified more than once. When
6256 grepping $at_help_all for keywords, use the field and keyword
6257 seperators to ensure a complete keyword match. Alter at_prev handling
6258 to support the new --keywords behavior.
6260 2003-04-27 Karl Berry <karl@freefriends.org>
6262 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6263 align better with others. I also made some of the individual
6264 entries on one line, for brevity and to make it easier for me to
6265 sort my dir-example file in the Texinfo distribution :).
6267 2003-04-12 Jim Meyering <jim@meyering.net>
6269 * NEWS: Mention the new macro.
6270 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

6305 New.
6306 Use them.
6307 * doc/Makefile.am (CLEANFILES): Adjust.
6308 (TEXI2DVI): Make it --batch.
6310 2003-03-31 Derek Price <derek@ximbiot.com>
6312 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
6313 which removed the main loop.
6314 Thanks to Akim Demaille.
6316 2003-03-29 Akim Demaille <akim@epita.fr>
6318 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
6319 that starts a GUI.
6320 From Ilya Zakharevich.
6322 2003-03-29 Akim Demaille <akim@epita.fr>
6324 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
6325 documentation to read is Autoconf's.
6326 Suggested by Paul Eggert.
6328 2003-03-28 Akim Demaille <akim@epita.fr>
6330 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
6331 reading the section "Present But Cannot Be Compiled" when the
6332 header causes problems.
6334 2003-03-28 Akim Demaille <akim@epita.fr>
6336 * tests/torture.at (Configuring subdirectories): Require aclocal
6337 1.4, otherwise the test fails, as it does support configure.ac.
6338 This fixes the "test 40 failed" bug reports.
6340 2003-03-28 Akim Demaille <akim@epita.fr>
6342 * doc/autoconf.texi (C Compiler): `#line' portability.
6343 From Paul Eggert and Nelson H. F. Beebe.
6345 2003-03-27 Derek Price <derek@ximbiot.com>
6347 * lib/autotest/general.m4: Eliminate main loop and reorganize test
6348 layout in order to allow scripting around test groups.
6350 2003-03-27 Derek Price <derek@ximbiot.com>
6352 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
6353 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
6354 use new diversions in preparation for accepting new arguments and

6371 sense. Verbosify the diversion definitions comment.
6373 2003-03-26 Derek Price <derek@ximbiot.com>
6375 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
6376 AS_PREPARE.

6397 file name for the m4 program, when it has an "exe" file extension.

6399 remove the error code during normalization.
6401 2003-02-28 Akim Demaille <akim@epita.fr>
6403 * doc/autoconf.texi (Present But Cannot Be Compiled): New.

6407 * doc/autoconf.texi (Limitations of Make): Remove the section
6408 about `$<' in inference rules, it was a bogus interpretation of
6409 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
6410 Tru64 make in the "target lookup" section.
6411 (Automake): Automake 1.5+ no longer requires special tools to be
6412 present on the developer's host.
6414 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
6416 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

6432 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6433 When constructing paths with IFS=:, quote the path. If we're
6434 constructing a DOS-style absolute path, we don't want to split it
6435 on the colon.

6486 innocuous variant befor including <limits.h> or <assert.h>. This
6487 works around a bug reported by Albert Chin: HP-UX 11i
6488 (and earlier versions) have a <limits.h> that declares
6489 gettimeofday and many other functions.
6491 2002-12-03 Paul Eggert <eggert@twinsun.com>
6493 Version 2.57.
6495 * NEWS, configure.ac: Update version.
6497 * doc/fdl.texi: Upgrade to FDL version 1.2.
6499 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6500 nontrivially in main's body, so that f's external declaration is
6501 not optimized away in AIX. This should fix the bug reported by
6502 Martin Frydl in
6503 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.

6545 2002-11-14 Akim Demaille <akim@epita.fr>
6547 * Makefile.maint: Sync with Bison, i.e.:
6548 (po-check): Scan .l and .y files instead of the
6549 .c and the .h files that they generate. This fixes the bug
6550 reported by Tim Van Holder in:
6551 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6552 Look for N_ as well as for _. Try to avoid matching #define for
6553 N_ and _.

6607 Reported by Ezra Peisach.
6609 2002-11-05 Akim Demaille <akim@epita.fr>
6611 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6612 Remove.
6613 We _have_ to stop using the old compatibility scheme that tried to
6614 avoid useless backslashes because Libtool 1.4.3 contains a
6615 AC_DEFINE([error_t], [int],
6616 [Define to a type to use for \`error_t' if it is not
6617 otherwise available.])
6618 We _have_ to quote the single quote and backslashes with \. The
6619 old compatibility scheme saw that ` was backslashed, and therefore
6620 did not quote the single quote. Hence before this patch, Autoconf
6621 was not compatible with Libtool.
6623 2002-11-04 Paul Eggert <eggert@twinsun.com>
6625 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6644 Support -m/--make.
6645 * doc/autoconf.texi (autoreconf Invocation): Adjust.

6665 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6666 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6667 Make variable, not a shell variable.
6668 Suggested by Bruno Haible.
6670 2002-10-31 Akim Demaille <akim@epita.fr>
6672 * bin/autom4te.in (load_configuration): Reject #args out of any
6673 language.

6689 Suggested by Tim van Holder.

6694 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
6695 Problem reported by Bruno Haible.
6697 2002-10-29 Akim Demaille <akim@epita.fr>
6699 * doc/autoconf.texi (Header Templates): Put also in words what the
6700 pictures says to assist free style readers.
6701 (Customizing autom4te): s/--cache=/--cache /.
6703 2002-10-29 Akim Demaille <akim@epita.fr>
6705 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
6706 sys/wait.h.

6953 2002-10-22 Akim Demaille <akim@epita.fr>
6955 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
6956 are a few warnings.
6957 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
6958 Quote for Perl '' strings, not "".
6959 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
6960 strings.
6962 2002-10-22 Akim Demaille <akim@epita.fr>
6964 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
6965 characters is a syntax warning now.

6973 Reported by Carlos Velasco.
6975 2002-10-18 Akim Demaille <akim@epita.fr>
6977 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that

6987 2002-10-17 Akim Demaille <akim@epita.fr>
6989 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.

7010 Because of caching, some files that no longer exist and are no
7011 longer required can still cause errors.
7012 Reported by Alexandre Duret-Lutz.
7014 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7015 to frozen files in @ARGV, as @ARGV must remain being a list of
7016 files. Rather, at M4 call sites, use this...
7017 (&files_to_options): New function.
7018 (&freeze): Use &error.
7019 (&up_to_date): If a file that was included according to the cache
7020 is no longer there, then the output is out dated.
7021 (&main): Don't even check whether a file is up to date is anyway
7022 --force is given.
7023 * tests/tools.at (autom4te cache): New.
7025 2002-10-16 Akim Demaille <akim@epita.fr>
7027 * bin/autoconf.as: Kill dead options.
7028 * bin/autoupdate.in (&parse_args): Kill old options.
7029 * bin/autoreconf.in (&parse_args): Remove dead options.
7030 Factor some code.
7031 (&autoreconf): Report the directories we enter *and leave*, so
7032 that error messages can be easily located, and use GNU Make
7033 format, so that Emacs' compile mode understands us.
7034 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7035 if some file was changed instead of `print'.
7036 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
7037 (&parse_args): Remove the dead options.
7038 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new

7047 check for compilability.
7049 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
7050 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

7054 * lib/autotest/general.m4 (AT_INIT): Include the failed test
7055 numbers in the Subject suggestion.

7069 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
7070 file name to enable parallel executions.
7071 From Sam Varshavchik.
7073 2002-10-08 Akim Demaille <akim@epita.fr>
7075 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7076 aclocal invocation, as Gettext macros might not be visible to
7077 aclocal.
7078 Instead of blindly running autopoint, scan configure.ac (not the
7079 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7080 Reported by Paul D. Smith.
7082 2002-10-08 Paul Eggert <eggert@twinsun.com>
7084 Work around problems found when POSIXLY_CORRECT=1 is set.
7085 None of this seems to have anything to do with POSIX, really,
7086 but it's how Perl getopt works.
7087 * bin/autom4te.in (parse_args): Configure GetOpt with
7088 "permute", too.
7089 * doc/autoconf.texi (Invoking autom4te):
7090 --warning -> --warnings.
7091 * lib/autom4te.in: --warning -> --warnings.

7110 2002-09-28 Akim Demaille <akim@epita.fr>
7112 * tests/torture.at (Configuring subdirectories): Be robust to
7113 users who use config.site to require for a cache: in this case,
7114 the two last configure runs, using two different sets of
7115 arguments, trigger a legitimate error.
7117 2002-09-28 Akim Demaille <akim@epita.fr>
7119 * tests/m4sh.at (Functions Support, Functions and return Support):
7120 New.

7133 (tm_zone): Move their rules to...
7134 * lib/autoconf/types.m4: here, using AN_ macros.
7135 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7136 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7137 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7138 * lib/autoconf/programs.m4: here.

7150 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7151 (.m4.m4f): Don't pass --prepend-include, since that's done by
7152 tests/autom4te itself.
7153 * lib/autoscan/Makefile.am: Include freeze.mk.
7154 (autoscan.list): New target --this file is no longer a source.
7155 (autoscan.pre): New file.
7157 2002-09-28 Akim Demaille <akim@epita.fr>
7159 * bin/autoscan.in (@kinds): Make them singular.
7160 Adjust all uses.
7161 (&init_tables): When --debug, report the list of rules to ease
7162 tracking changes in autoscan.list.
7163 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7165 2002-09-28 Akim Demaille <akim@epita.fr>

7176 * lib/autoscan/identifiers, lib/autoscan/makevars,
7177 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7178 `functions' line is now prefixed with `function:'.
7179 * bin/autoscan.in (&init_tables): Adjust.
7181 2002-09-28 Akim Demaille <akim@epita.fr>
7183 From now on, autoscan files must always map a macro name to a
7184 word: there is no `default' macro for autoscan.
7186 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7187 all.
7188 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7189 explicit.
7191 2002-09-28 Akim Demaille <akim@epita.fr>
7193 * bin/autoscan.in (%c_keywords): Remove.
7194 (&used): Keep only track of the words we might be interested in.

7225 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7226 Reported by Ralf Corsepius.
7227 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7229 2002-09-26 Akim Demaille <akim@epita.fr>
7231 Single suffix rules and seperated dependencies are not portable.
7233 * doc/autoconf.texi (Installation Directory Variables): Update.
7234 (Limitations of Make): Some about `Single Suffix Rules and

7256 Reported by Ralf Corsepius.

7279 Suggested by Guido Draheim.
7281 2002-09-13 Akim Demaille <akim@epita.fr>
7283 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals

7287 2002-09-12 Akim Demaille <akim@epita.fr>
7289 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7290 the lists.
7292 2002-09-12 Akim Demaille <akim@epita.fr>
7294 * doc/autoconf.texi (Defining Symbols): Present two different

7306 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7307 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7308 is obsolescent.
7310 2002-09-11 Akim Demaille <akim@epita.fr>
7312 * doc/autoconf.texi (Questions): Rename as...

7329 `duplicates', since the algorithm was too naive and could keep
7330 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7331 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7332 Reported by Ralf Corsepius.

7343 directory definition.
7344 Reported by Andreas Schwab and Jim Meyering.
7346 2002-09-06 Akim Demaille <akim@epita.fr>

7349 precious variables are.
7350 Suggested by Pontus Skoeld.
7352 2002-09-05 Akim Demaille <akim@epita.fr>
7354 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7355 (ifnames, autoscan, autom4te): Since we don't only depend on
7356 configure.ac variables (such as VERSION etc.), but also on prefix
7357 and so forth, depend on Makefile, not configure.ac.
7358 Reported by Alexandre Duret-Lutz.
7359 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7361 2002-09-05 Kevin Ryde <user42@zip.com.au>

7383 as of today, on Automake's team suggestion.
7385 2002-09-03 Akim Demaille <akim@epita.fr>

7403 * doc/autoconf.texi (Limitations of Builtins): Explain why logical

7408 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7409 Reported by Raja R. Harinath.
7410 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7411 * bin/autoupdate.in: Use error instead of die.
7413 2002-09-01 Paul Eggert <eggert@twinsun.com>
7415 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7416 ordinary shell concatenation rather than echo+tr+sed command that
7417 runs afoul of a long-line-related sed bug in Solaris 8.
7419 * bin/autoheader.in (parse_args): --warning -> --warnings.
7421 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7422 stdout, as traditional "ls" does.
7423 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7424 _AC_COMPILER_EXEEXT_O): Likewise.
7425 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7427 * bin/autoconf.as: Add --prepend-include option. This patch was
7428 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7429 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7431 * bin/autoconf.in, configure: Regenerate.
7433 * doc/autoconf.texi (Special Shell Variables): Mention
7434 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7436 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7437 MAILPATH and set PS1, PS2, PS4 to default values, to work
7438 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7439 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7440 the Autoconf documentation specifies; fall back to "unset" only if
7441 this fails. Use a shell for-loop for this rather than an m4 loop,
7442 to shorten the output script.
7444 2002-08-30 Paul Eggert <eggert@twinsun.com>
7446 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7447 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7448 for the CDPATH problem. Document PWD.
7449 (Limitations of Builtins): Document the problem that "cd $foo" and
7450 "ls $foo" may refer to different directories in shells conforming
7451 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7452 example, since the old example is now out of date.
7454 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7455 FOO" and "ls FOO" talk about different directories; this catches
7456 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7457 spaghetti.
7459 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7460 of rolling our own unset.
7461 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7462 in practice we needn't worry about CDPATH if unset doesn't work.
7464 * Makefile.in, aclocal.m4, bin/Makefile.in,
7465 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7466 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7467 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7468 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7469 tests/Makefile.in: Regenerate with Automake 1.6.3.
7471 * config/config.guess, config/config.sub, config/mkinstalldirs:
7472 Update.
7474 * configure: Regenerate with self.
7476 2002-08-30 Kevin Ryde <user42@zip.com.au>
7478 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7479 default output.
7481 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7483 * bin/autom4te.in (Request::load): Correctly test for "do" read
7484 failure.
7486 2002-08-29 Akim Demaille <akim@epita.fr>
7488 * lib/Autom4te/General.pm (&xqx): New.
7489 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7490 hand, which is not portable.
7491 (&error): New.
7492 * bin/autom4te.in: Use them.
7493 Use &error instead of die.
7494 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7495 Adjust.
7497 2002-08-17 Paul Eggert <eggert@twinsun.com>
7499 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7500 default list of compilers to try, since it was long ago superseded
7501 by the ksh fc builtin. Suggested by Steven G. Johnson.
7503 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7505 * doc/autoconf.texi (Invoking autom4te): End the option table,
7506 fixing a bug introduced by the previous patch.
7507 (Limitations of Make): Add a 'target lookup' subentry in the
7508 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7510 2002-07-29 Mark D. Roth <roth@feep.net>
7512 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7513 options and use $AUTOM4TE_PATH.
7514 * doc/autoconf.texi: Remove documentation of autom4te
7515 --include-envvar and --site-macro-subdir options and document
7516 use of $AUTOM4TE_PATH.
7517 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7518 arguments from each language section.
7520 2002-07-29 Paul Eggert <eggert@twinsun.com>
7522 * doc/install.texi: Include copyright symbol in copyright notice.
7524 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7525 Replace with:
7526 (AM_MAKEINFOFLAGS): New macro.
7527 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7528 * Makefile.am (INSTALL): Use the new macros.
7529 Use -o rather than --output, since "missing" does not grok --output.
7531 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7533 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7534 comments do not always work. Never trust the exit status of
7535 `make -k'.
7537 2002-07-24 Kevin Ryde <user42@zip.com.au>
7539 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7540 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7542 2002-07-23 Paul Eggert <eggert@twinsun.com>
7544 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7545 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7546 apparently treats PATH="nonexistent" as if it contained ".".
7547 Bug reported by Stefan `Sec' Zehl.
7549 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7551 * doc/autoconf.texi (Limitations of Make): Mention the special
7552 handling of the obj/ directory by BSD make.
7554 2002-07-20 Kevin Ryde <user42@zip.com.au>
7556 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
7557 backslashes.

7568 2002-07-18 Akim Demaille <akim@epita.fr>
7570 Version 2.53b.
7572 2002-07-18 Akim Demaille <akim@epita.fr>
7574 * config/config.guess, config/config.sub: Update.
7576 2002-07-18 Akim Demaille <akim@epita.fr>
7578 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
7579 Automake's parts.

7582 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
7583 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
7585 2002-07-18 Akim Demaille <akim@epita.fr>,
7586 Alexandre Duret-Lutz <duret_g@epita.fr>
7588 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
7589 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

7598 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
7599 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
7600 latter was not run.

7604 * lib/Autom4te/General.pm (find_file): Browse the directories in
7605 the order they are given.

7666 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
7668 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7669 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
7670 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
7671 so that Emacs setups GNU style for perl-mode and cperl-mode.
7673 2002-06-27 Paul Eggert <eggert@twinsun.com>
7675 * config/install-sh: Quote $src. Prefer || to test's -o option,
7676 as per "Limitations of Builtins".
7677 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7678 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7680 * tests/mktests.sh: Use grep instead of fgrep, as per
7681 "Limitations of Builtins".
7683 2002-06-15 Paul Eggert <eggert@twinsun.com>
7685 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7686 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7687 so that we consistently test the just-built programs.
7688 * tests/wrappl.as: Likewise.
7690 2002-06-12 Paul Eggert <eggert@twinsun.com>
7692 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
7693 name, so that symlinks to 'autoconf' work properly. Bug reported
7694 by Bruno Haible.
7695 * bin/autoheader.in (AUTOM4TE): Likewise.
7696 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7697 * bin/autoscan.in (autom4te): Likewise.
7698 * bin/autoupdate.in (autom4te): Likewise.
7700 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7701 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7702 on Solaris 2.5.1.
7704 2002-06-11 Andreas Schwab <schwab@suse.de>
7706 * doc/autoconf.texi: Add more dir entries.
7708 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7710 * bin/autom4te.in ($cache): Don't define using `$me', the name
7711 of the cache should not depend on the name under which autom4te
7712 was installed.
7714 2002-06-07 Akim Demaille <akim@epita.fr>
7716 * tests/tools.at (autoconf: forbidden tokens, basic)
7717 (autoconf: forbidden tokens, exceptions): Adjust to the change of
7718 words in autom4te.in.
7720 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7722 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7723 _AC_LANG_PROGRAM_C_F77_HOOKS.
7725 2002-06-07 Akim Demaille <akim@epita.fr>
7727 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
7728 rename as...
7729 (AC_REPLACE_FNMATCH): this.
7730 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
7731 AC_FUNC_FNMATCH_GNU.
7733 2002-06-07 Akim Demaille <akim@epita.fr>
7735 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7736 Rosetta Stone for Unix.
7738 2002-06-07 Akim Demaille <akim@epita.fr>
7740 * bin/autom4te.in (warn_forbidden): When rejecting a token,
7741 suggest m4_pattern_allow.
7742 Suggested by Adam J. Richter.
7744 2002-06-07 Akim Demaille <akim@epita.fr>
7746 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
7747 ac_config_libobj_dir.
7748 (AC_CONFIG_LIBOBJ_DIR): New.
7749 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
7750 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
7751 Use ac_config_libobj_dir to find the replacement files.
7752 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
7753 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
7754 (AC_REPLACE_FNMATCH_GNU): these.
7755 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
7756 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
7757 * tests/mktests.sh (ac_exclude_list): Don't check
7758 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
7760 2002-06-06 Paul Eggert <eggert@twinsun.com>
7762 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7763 if ln doesn't work.
7764 * NEWS: Likewise.
7765 * doc/autoconf.texi (Configuration Links): Likewise.
7766 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
7768 2002-06-05 Paul Eggert <eggert@twinsun.com>
7770 * config/config.guess, config/config.sub, config/texinfo.tex:
7771 Update from masters.
7773 2002-05-29 Paul Eggert <eggert@twinsun.com>
7775 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
7776 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
7777 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

7784 * lib/m4sugar/Makefile.am (check-local): Likewise.
7785 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
7786 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
7788 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
7789 * doc/autoconf.texi (Particular Programs): Document them.
7790 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
7791 * NEWS: Likewise.
7793 2002-05-27 Paul Eggert <eggert@twinsun.com>
7795 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
7796 * NEWS, doc/autoconf.texi (Particular Types): Document it.
7797 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
7798 instead of AC_MBSTATE_T, which never existed.
7800 2002-05-23 Akim Demaille <akim@epita.fr>
7802 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7803 version of Autoconf that is discussed.
7805 2002-05-22 Paul Eggert <eggert@twinsun.com>
7807 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7808 from the default list of compilers to try. Suggested by
7809 Kate Hedstrom.
7810 * NEWS: Document the above.
7811 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7813 2002-05-17 Paul Eggert <eggert@twinsun.com>
7815 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7816 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7817 This improves on an earlier suggestion by H. Peter Anvin.
7819 2002-05-16 Paul Eggert <eggert@twinsun.com>
7821 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7822 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7823 Both macros now accept an optional source-dir arg.
7824 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7826 * NEWS: Document this.
7827 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7829 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7830 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7831 not for GNU extensions; this undoes part of the 2000-11-03 change,
7832 reverting to 2.13-compatible behavior.
7833 Add new optional argument DIR.
7834 (AC_FUNC_FNMATCH_GNU): New macro.
7836 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7838 2002-05-08 Paul Eggert <eggert@twinsun.com>
7840 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7841 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7842 and it causes a 'test' syntax error if it fails.
7843 Bug reported by Stephen Gildea.
7845 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7846 If prototypes are supported, use them to check this at compile-time,
7847 instead of trying to check it at run-time. If we must do a run-time
7848 check, assume that setvbuf is standard when cross-compiling, as
7849 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7850 Bug reported by Paul D. Smith.
7852 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7853 argument specifying location of getloadavg.c. This removes a
7854 FIXME. This idea was taken from Jim Meyering's implementation in
7855 textutils.
7856 * doc/autoconf.texi (Particular Functions): Document this.
7857 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7858 that's what the code does; this fixes a bug reported by
7859 Paul D. Smith.
7861 2002-05-03 Akim Demaille <akim@epita.fr>
7863 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7864 autopoint instead of gettextize.
7865 ($uses_alocal): Rename as...
7866 ($uses_aclocal): this.
7867 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7868 Suggested by Bruno Haible.
7870 2002-05-03 Akim Demaille <akim@epita.fr>
7872 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7874 2002-04-29 Paul Eggert <eggert@twinsun.com>
7876 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7877 files to be 1 second older; just set them to be the same time.
7878 Also, sleep 1 second after the first aclocal, to work around
7879 problems with sub-second time stamps on the input files.
7881 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7883 * doc/autoconf.texi: Mention "set -e -x" lossage
7884 under node "Limitations of Builtins".
7886 2002-04-29 Akim Demaille <akim@epita.fr>
7888 * doc/install.texi: Better wording for setting variables when
7889 running configure.
7890 From Christian Cornelssen.
7892 2002-04-29 Akim Demaille <akim@epita.fr>
7894 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7895 of lack of $LINENO support, then the test will compare the $LINENO
7896 in testsuite vs. the lineno in the test file. This is wrong, of
7897 course.
7898 Be sure to protect it.
7899 Reported by Patrick Welche.
7901 2002-04-25 Akim Demaille <akim@epita.fr>
7903 * doc/autoconf.texi (Obsolete Macros): Typo.
7904 Reported by Vladimir Volovich.
7906 2002-04-25 Akim Demaille <akim@epita.fr>
7908 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7909 than some of the input files, hence, on the second run of aclocal,
7910 if some of its input are younger, make them older.
7911 Suggested by Paul Eggert.
7913 2002-04-25 Akim Demaille <akim@epita.fr>
7915 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7916 Thanks to Paul Eggert.
7918 2002-04-25 Akim Demaille <akim@epita.fr>
7920 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7921 and ac_subst_vars be sh variables containing the list of
7922 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7923 DEFAULT diversion.
7924 (_AC_INIT_PREPARE): Use them to log them.
7925 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7926 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7927 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7928 _AC_SUBST_FILES and _AC_SUBST_VARS.
7929 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7931 2002-04-24 Akim Demaille <akim@epita.fr>
7933 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7934 autoheader, so that automake does not complain about a missing
7935 config.h.in that was to be created.
7937 2002-04-23 Akim Demaille <akim@epita.fr>
7939 * bin/autoheader.in (parse_args): --warning takes an argument.
7940 Fixes PR/220.
7942 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7944 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
7945 and bb.out when cleaning up.

7953 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
7955 2002-04-22 Akim Demaille <akim@epita.fr>
7957 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
7958 comma.
7959 Reported by Gregory Giannoni.
7961 2002-04-22 Akim Demaille <akim@epita.fr>
7963 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
7964 Fixes false failures on Darwin.

7970 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

7988 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
7989 Minor spelling and grammar fixes.
7991 * doc/autoconf.texi: Follow the outline suggested in the GNU
7992 Sample Texts sections of the Texinfo 4.2 manual. Most
7993 importantly, this makes sure that the copyright notices appear in
7994 all output formats. You probably need Texinfo 4.2 to generate
7995 the manual now.
7997 Fix some bugs when using "$@" when there might be zero positional
7998 arguments in cases where this matters.
8000 * bin/autoconf.as: Rewrite so that the problem does not come up.

8018 * tests/c.at: We can't have zero arguments, so remove workaround
8019 that is not portable to Zsh.
8021 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8023 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8024 from aclocal.m4 too.
8026 2002-04-12 Akim Demaille <akim@epita.fr>
8028 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
8030 2002-04-10 Akim Demaille <akim@epita.fr>
8032 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8033 workaround for ${1+"$@"}.
8034 * doc/autoconf.texi (Shell Substitutions): Explain it.
8035 From Oliver Kiddle and Peter Stephenson.
8037 Have M4sh perform minimal shell sanitizing.
8039 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8040 part into...
8041 (_AS_PREPARE): this new macro.
8042 (AS_PREPARE): New.
8043 (AS_INIT): Invoke AS_SHELL_SANITIZE.
8044 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8046 Adjust Autoconf and Autotest.
8048 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8049 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8050 * lib/autotest/general.m4 (AT_INIT): Likewise.
8051 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8052 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8053 AS_SHELL_SANITIZE.
8055 Use this M4sh to generate Autoconf's shell scripts.
8057 * tests/wrapsh.as: New, precursor of wrapsh.in.
8058 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8059 on Autotest and M4sh.
8060 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8061 (wrapsh.in): New target.
8062 * bin/autoconf.as: New, precursor of autoconf.in.
8063 (autoconf.in): New target.
8065 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

8068 with indented comments in rules.
8070 2002-04-09 Andreas Schwab <schwab@suse.de>
8072 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
8073 ac_top_builddir when setting ac_abs_top_builddir.
8075 2002-04-06 Kevin Ryde <user42@zip.com.au>
8077 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
8078 (Portable Shell): Cross reference to Systemology.
8080 2002-04-05 Akim Demaille <akim@epita.fr>
8082 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8083 directories when descending in a SUBDIRS.
8084 Reported by Ezra Peisach.
8086 2002-04-04 Andreas Schwab <schwab@suse.de>
8088 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8089 contains no literal separators.
8091 2002-04-03 Akim Demaille <akim@epita.fr>
8093 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8094 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8095 Use dnl, not the KILL diversion.
8096 Extracted from...
8097 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8098 (AC_CONFIG_LINKS): here.
8099 Adjust.
8100 Don't use the KILL diversion, as it kills spurious output, which
8101 results in failures being hidden.
8102 Use m4_defn where appropriate.
8103 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8104 after the second argument.
8105 Use m4_defn.
8106 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8107 syntax, as it is provided by M4sugar.
8108 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
8110 2002-04-03 Andreas Schwab <schwab@suse.de>
8112 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
8113 expanded if $# <= 2.

8116 aclocal.
8118 2002-04-03 Akim Demaille <akim@epita.fr>
8120 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)

8122 Also recognize *.bb and *.bbg as compilation byproducts.
8123 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
8124 (_AC_COMPILER_OBJEXT): Use them.
8125 Fixes Debian #138666.
8127 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
8129 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
8131 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
8132 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
8133 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
8134 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
8135 (AC_C_CONST): Same.

8138 * doc/autoconf.texi, NEWS: Document.
8139 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
8140 AC_C_CROSS.

8145 _AS_MKDIR_P_PREPARE.
8147 2002-03-28 Kevin Ryde <user42@zip.com.au>
8149 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8150 to avoid versions of HP C which don't allow that.
8152 2002-03-27 Paul Eggert <eggert@twinsun.com>
8154 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8155 (AS_SHELL_SANITIZE): Invoke it.
8156 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
8158 2002-03-26 Akim Demaille <akim@epita.fr>
8160 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
8162 2002-03-26 Akim Demaille <akim@epita.fr>
8164 * doc/autoconf.texi (Introduction): The GNATS base moved.
8166 2002-03-25 Paul Eggert <eggert@twinsun.com>
8168 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8169 as POSIX requires, as it doesn't work with Zsh.
8170 * doc/autoconf.texi (Assignments): Document the problem.
8172 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8174 * doc/autoconf.texi (Limitations of Make): Mention more issue
8175 about VPATH, overriding of macros in sub-makes, and handling of
8176 SHELL.
8178 2002-03-21 Paul Eggert <eggert@twinsun.com>
8180 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8181 problem with here-document buffer boundaries.
8183 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8184 when reinvoking the shell, to work around problems with installers
8185 who put strange things like "cd" commands in their environments.
8187 2002-03-19 Akim Demaille <akim@epita.fr>
8189 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8190 From Aaron Ucko.
8192 2002-03-19 Akim Demaille <akim@epita.fr>
8194 * bin/autoscan.in (scan_file): Specify the location in `&used'
8195 invocations.
8196 From Nicolas Joly.
8198 2002-03-19 Akim Demaille <akim@epita.fr>
8200 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8201 From Nishio Futoshi.
8203 2002-03-19 Akim Demaille <akim@epita.fr>
8205 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8207 2002-03-18 Paul Eggert <eggert@twinsun.com>
8209 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8210 (Limitations of Usual Tools): Add mkdir section.
8212 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8213 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8214 back on AS_DIRNAME to compute prefixes otherwise; this is
8215 roughly what mkinstalldirs does. That way, we need not have
8216 our own filename disassembler. The old disassembler did not
8217 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8219 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8220 Create at_test_all by a series of assignments,
8221 not by a single assignment of a long string. The latter causes ksh
8222 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8223 presumably because of a buffer overrun.
8225 2002-03-14 Paul Eggert <eggert@twinsun.com>
8227 * lib/autotest/general.m4 (at_times_skip):
8228 Renamed from at_times. Now a boolean.
8229 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8230 says 'times: not found'.
8232 2002-03-14 Akim Demaille <akim@epita.fr>
8234 * bin/autoreconf.in (&study_gettextize): New.
8235 (&autoreconf): Handle newest gettextize.
8236 Rerun aclocal if needed.
8237 Suggested by Andreas Schwab.
8239 2002-03-13 Akim Demaille <akim@epita.fr>
8241 * doc/autoconf.texi (Special Shell Variables): More about IFS.
8243 2002-03-13 Akim Demaille <akim@epita.fr>
8245 * doc/autoconf.texi (Header Portability): New.
8246 Add information about stdint.h and inttypes.h from Paul Eggert.
8248 2002-03-13 Akim Demaille <akim@epita.fr>
8250 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8251 -p'.
8252 From Bob Proulx.
8254 2002-03-12 Akim Demaille <akim@epita.fr>
8256 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8257 m4_require.
8259 2002-03-11 Andreas Schwab <schwab@suse.de>
8261 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8262 does not do it if --with-lispdir is given.
8264 2002-03-08 Akim Demaille <akim@epita.fr>
8266 Version 2.53.
8268 2002-03-08 Akim Demaille <akim@epita.fr>
8270 * doc/autoconf.texi (Subdirectories): Clarify that the
8271 subdirectory should exist.
8273 2002-03-08 Akim Demaille <akim@epita.fr>
8275 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8277 2002-03-08 Akim Demaille <akim@epita.fr>
8279 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8280 aliases the actual variables, and modifications of the former
8281 affect the latter.
8283 2002-03-08 Akim Demaille <akim@epita.fr>
8285 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8286 because of C-c: have m4 output in tmp files, then mv them.
8288 2002-03-08 Akim Demaille <akim@epita.fr>
8290 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8291 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8292 * bin/ifnames.in: Copyright update.
8294 2002-03-08 Akim Demaille <akim@epita.fr>
8296 * doc/autoconf.texi (Invoking autom4te): New.
8298 2002-03-05 Akim Demaille <akim@epita.fr>
8300 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8301 Kevin Ryde.
8303 2002-03-05 Akim Demaille <akim@epita.fr>
8305 Version 2.52i.
8307 2002-03-04 Akim Demaille <akim@epita.fr>
8309 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8310 * lib/autoconf/general.m4 (AC_INIT): More informative error
8311 message for LIBOBJ.
8313 2002-03-04 Akim Demaille <akim@epita.fr>
8315 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8316 parallel builds.
8318 2002-03-04 Akim Demaille <akim@epita.fr>
8320 * doc/autoconf.texi (Transforming Names): Equality between target
8321 and host is irrelevant.
8322 (Specifying Names, Canonicalizing): Remove all references to the
8323 backward compatibility hooks. Rather, collect them all into...
8324 (Hosts and Cross-Compilation): this new section.
8325 * doc/install.texi (System Type): Ditto.
8326 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8327 that `--host' implies cross-compilation.
8329 2002-03-04 Akim Demaille <akim@epita.fr>
8331 * doc/autoconf.texi (Evaluation Macros): New.
8332 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8333 useless.
8334 (_m4_foreach): Define the variant with immediate evaluation so
8335 that it contains exactly the items, not an expression which
8336 evaluation is the current item.
8337 (m4_re_string, m4_re_word): Don't over quote them.
8339 2002-03-04 Akim Demaille <akim@epita.fr>
8341 Instead of having stacking `shift's evaluated at the end, let
8342 `foreach' loops immediately evaluate them.
8344 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8345 $*. This is the n-th time I change my mind, but hopefully this is
8346 the last...
8347 (m4_lquote): New.
8348 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8349 efficient.
8350 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8351 it was only a hack for m4_text_wrap.
8352 (m4_car2): Remove, replaced by...
8353 (m4_cdr): New.
8354 (_m4_foreach): Adjust.
8355 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8356 m4_bpatsubst for clarification.

8391 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8392 translate \r\n to \n.
8394 2002-02-07 Akim Demaille <akim@epita.fr>
8396 Version 2.52h.
8398 2002-02-07 Akim Demaille <akim@epita.fr>
8400 Fix Autoconf PR/209.
8401 Also reported by Frank Denis.
8403 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
8405 2002-02-07 Akim Demaille <akim@epita.fr>
8407 Fix Autoconf PR/207:
8408 AC_PREFIX_PROGRAM fails with dashed program names
8410 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8411 variable when looking for the prefix program.
8412 Now it also works for shell variables.
8414 2002-02-07 Akim Demaille <akim@epita.fr>
8416 * doc/autoconf.texi (Limitations of Builtins): More about
8417 case/esac.
8419 2002-02-06 Akim Demaille <akim@epita.fr>
8421 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
8422 case/esac, some shells don't support it.
8423 Reported by Zack Weinberg.
8424 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
8426 2002-02-06 Akim Demaille <akim@epita.fr>
8428 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8429 sure not to introduce newlines in at_groups.
8430 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8432 2002-02-06 Akim Demaille <akim@epita.fr>
8434 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8435 is not available.
8437 2002-02-05 Paul Eggert <eggert@twinsun.com>
8439 * doc/autoconf.texi (Specific Compiler Characteristics):
8440 Describe HP-UX cc bug workaround more accurately.
8441 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
8442 not unsigned long.
8443 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8444 cross-compilers, too. This undoes some of the most recent change
8445 to this file.
8447 2002-02-05 Akim Demaille <akim@epita.fr>
8449 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8450 to make sure they are up to date when `check' is run.
8452 2002-02-05 Akim Demaille <akim@epita.fr>
8454 * doc/autoconf.texi (Making testsuite Scripts): Document
8455 package.m4.
8457 2002-02-05 Akim Demaille <akim@epita.fr>
8459 * lib/freeze.mk: New.
8461 2002-02-05 Akim Demaille <akim@epita.fr>
8463 Implement `autom4te --freeze'.
8465 * bin/autom4te.in (&freeze): New.
8466 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8467 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8469 2002-02-05 Akim Demaille <akim@epita.fr>
8471 * bin/autom4te.in (&parse_args): Implement `frozen files are
8472 optional are the sum of the previous files on the command line'.
8473 Also, pass `--reload-state=' on them, so...
8474 (handle_m4): don't.
8475 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8476 (M4sh): Rely on M4sugar.
8477 (Autotest, M4sh, M4sugar): Use frozen files.
8479 2002-01-31 Akim Demaille <akim@epita.fr>
8481 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8482 * doc/autoconf.texi (Initializing configure): Adjust.
8484 2002-01-30 Akim Demaille <akim@epita.fr>
8486 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8487 alphanumeric to `-' instead of `_'.
8489 2002-01-30 Akim Demaille <akim@epita.fr>
8491 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8492 for plain code, the other for cross-compilation code. The latter
8493 is now run with GCC only.
8494 * doc/autoconf.texi (Compilers and Preprocessors): New.
8496 2002-01-30 Akim Demaille <akim@epita.fr>
8498 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8499 values.
8500 * doc/autoconf.texi (Initializing configure): Explain how to
8501 change AC_INIT default values.
8503 2002-01-29 Akim Demaille <akim@epita.fr>
8505 * tests/torture.at (Configuring subdirectories): Use configure.in,
8506 so that aclocal 1.4 works.
8507 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8509 2002-01-28 Akim Demaille <akim@epita.fr>
8511 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8512 needs an argument.
8514 2002-01-28 Akim Demaille <akim@epita.fr>
8516 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8517 AUTOTEST_PATH *after* it was set.
8518 Don't put `.' in the PATH: the user should be precise and `./' if
8519 needed. In addition, given that the test suite does some `cd', if
8520 `.' is in the path, the `tested programs' sections will report
8521 programs found in the test suite's directory, while during the
8522 tests (performed in their own directory), these programs are no
8523 longer visible. In other words, the results is confusing and
8524 useless.
8525 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8527 2002-01-24 Akim Demaille <akim@epita.fr>
8529 Version 2.52g.
8531 2002-01-24 Akim Demaille <akim@epita.fr>
8533 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
8534 * doc/autoconf.texi: Finally add Akim as an author.
8536 2002-01-24 Akim Demaille <akim@epita.fr>
8538 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8539 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8540 Bourne. Use /bin/sh.
8541 From Andreas Buening.
8543 2002-01-24 Akim Demaille <akim@epita.fr>
8545 * config/config.guess, config/config.sub, config/texinfo.tex:
8546 Update from masters.
8548 2002-01-24 Akim Demaille <akim@epita.fr>
8550 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
8551 * config/auxdir.m4, config/cond.m4, config/depend.m4,
8552 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
8553 * config/missing.m4, config/sanity.m4, config/select.m4,
8554 * config/strip.m4: Remove, to ease sync'ing with any version of
8555 Automake.
8557 2002-01-24 Akim Demaille <akim@epita.fr>
8559 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8560 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
8561 Reported by Geir Ove Myhr.
8563 2002-01-21 Akim Demaille <akim@epita.fr>
8565 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
8567 2002-01-21 Akim Demaille <akim@epita.fr>
8569 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8570 message on invalid options.
8571 * bin/autom4te.in (parse_args): Don't use
8572 Autoconf::General::getopt with non valid options.
8574 2002-01-17 Jim Meyering <meyering@lucent.com>
8576 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8577 $ac_cv_exeext so we don't use an old, invalid, cached value.
8579 2002-01-11 Akim Demaille <akim@epita.fr>
8581 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
8582 Meyering.
8583 * doc/autoconf.texi (Function Portability): Document the strnlen
8584 limitation.

8586 * lib/autoscan/functions: Adjust.
8588 2002-01-06 Akim Demaille <akim@epita.fr>
8590 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8591 package.m4, since is really depends upon configure.ac, not
8592 configure.
8593 * doc/autoconf.texi (testsuite Scripts): Adjust.
8594 * tests/Makefile.am (package.m4): New.
8595 EXTRA_DIST it since its a source.
8597 2002-01-06 Akim Demaille <akim@epita.fr>
8599 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8600 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8601 and PACKAGE_BUGREPORT from here...
8602 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8603 arguments.
8604 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8605 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8606 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8607 * tests/tools.at (autoheader): Adjust.
8608 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8610 2002-01-06 Akim Demaille <akim@epita.fr>
8612 * bin/autoscan.in (scan_file): Use `&used'.
8614 2002-01-03 Akim Demaille <akim@epita.fr>
8616 * doc/autoconf.texi (Output): Improved wording regarding use of
8617 AC_OUTPUT.
8618 From Olly Betts.
8620 2001-12-18 Kevin Ryde <user42@zip.com.au>
8622 * doc/autoconf.texi (Function Portability): Add notes on sscanf
8623 sometimes needing writable input.
8625 2001-12-17 Jim Meyering <meyering@lucent.com>
8627 * doc/autoconf.texi (New Macros): Tweak wording.
8629 2001-12-14 Akim Demaille <akim@epita.fr>
8631 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8632 trailing files, don't apply `-rf' to files which might not be
8633 created by configure (core, core.*, and *.core), but just `rm -f'.
8634 Suggested by Jonathan Kamens.
8636 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8638 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8640 2001-12-14 Akim Demaille <akim@epita.fr>
8642 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8644 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8646 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8647 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8648 abs_srcdir, top_srcpath to abs_top_srcdir.
8649 (_AC_OUTPUT_FILES): Adjust.
8650 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8651 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8652 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8654 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8656 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8657 C/Fortran linking on HP/UX, by extracting the Fortran library
8658 search path from the LPATH line in the $F77 -v output.
8660 2001-12-12 Kevin Ryde <user42@zip.com.au>
8662 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8663 forbidden file descriptors table.
8665 2001-11-26 Akim Demaille <akim@epita.fr>
8667 * bin/autoscan.in (%c_keywords): Build it at top level.
8668 Map to 1 in order to simplify its uses.
8670 2001-11-26 Akim Demaille <akim@epita.fr>
8672 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8673 Remove $filepath, useless.
8674 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8675 variables, they are really part of the tokens.
8676 Split the input line on spaces and then look for tokens.
8677 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8678 because of `lex$U.$(OBJEXT)'.
8679 (&scan_files): Use "@list" instead of join.
8680 * doc/Makefile.am (CLEANFILES): Add *.fns.
8682 2001-11-26 Akim Demaille <akim@epita.fr>
8684 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8685 Remove, replaced by...
8686 * tests/wrappl.in: Be common for all the Perl executables.
8687 In particular autoscan and autoheader want -I.
8688 * configure.ac: Adjust.
8689 * lib/autoscan/headers: errno.h is portable.
8691 2001-11-26 Akim Demaille <akim@epita.fr>
8693 * bin/autoscan.in (used): New.
8694 Use it.
8696 2001-11-26 Akim Demaille <akim@epita.fr>
8698 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8699 directives.
8700 (&scan_sh_file): Remove a duplicate pattern.
8701 (&check_configure_ac): Use long options.
8702 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8704 2001-11-26 Akim Demaille <akim@epita.fr>
8706 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8707 Before, having a line containing the opening of a multi line
8708 comment made the whole line be ignored.
8710 2001-11-26 Akim Demaille <akim@epita.fr>
8712 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8713 (testsuite Scripts): Be one of its subsection.
8714 (Autotest Logs): New.
8716 2001-11-26 Akim Demaille <akim@epita.fr>
8718 Test groups are now run two directories deeper.
8720 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8721 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8722 at_top_builddir.
8723 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8724 top_srcdir, builddir and top_builddir.
8725 Use `at_*dir' relatively to the directory containing the
8726 suite, use `*dir' when relatively to the current group dir.
8728 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8730 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8731 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8732 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8733 spelling errors.
8735 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8737 * doc/autoconf.texi (Using System Type): Add an example of `case
8738 $host' usage so people quit using `case $target' everywhere.
8740 2001-11-22 Akim Demaille <akim@epita.fr>
8742 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8743 spotted by Jim Meyering.
8745 2001-11-16 Paul Eggert <eggert@twinsun.com>
8747 This patch implements a `long double' suggestion by Oliver Kiddle.
8749 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8750 static, to catch errors if the value isn't known at compile-time
8751 and the compiler supports dynamic arrays. Change its name from
8752 `_array_' to `test_array' to avoid potential name clashes.
8753 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8754 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8755 better than double. Catch a bug in GCC 2.95.2 x86.
8756 * doc/autoconf.texi (C Compiler): Document the above.
8757 * NEWS: Likewise.
8759 2001-11-13 Akim Demaille <akim@epita.fr>
8761 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8762 hand.
8763 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8765 2001-11-13 Akim Demaille <akim@epita.fr>
8767 * lib/autotest/general.m4 (AT_INIT): After having run the test
8768 group, go back to the initial directory, not to at_suite_dir.
8770 2001-11-13 Akim Demaille <akim@epita.fr>
8772 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8773 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8774 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8775 option.
8776 (AT_CHECK_CONFIGURE): Use absolute paths.
8777 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8778 The problem is still the old one: there is no means in M4 (that I
8779 know about) to create a defining macro, because there is no means
8780 to create `$1' etc., therefore, the defining macro ``swallows''
8781 all the arguments meant to the defined macro.
8783 2001-11-13 Akim Demaille <akim@epita.fr>
8785 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8786 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8787 configure.ac.
8788 * tests/aclocal.m4: Remove, as it is no longer used.
8790 2001-11-13 Akim Demaille <akim@epita.fr>
8792 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8793 variable names when referring to a single test group, or to
8794 `suite' when referring to the whole test suite.
8795 `at_last_test' is removed: m4 compute at_format itself.
8796 (at_stdout, at_stder1, at_stderr): New variables.
8797 (AT_CHECK): Use them.
8799 2001-11-13 Akim Demaille <akim@epita.fr>
8801 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8802 in PATH.
8803 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8804 Do it as soon as a test fails, don't wait till the end of the test
8805 suite.
8806 Don't remove $as_me.[0-9]*, since these files no longer exist.
8808 2001-11-13 Akim Demaille <akim@epita.fr>
8810 * tests/tools.at: Use absolute paths, since we are no longer run
8811 in place.
8813 2001-11-13 Akim Demaille <akim@epita.fr>
8815 Now that tests are running in their own private dir, there is no
8816 need to list the files to remove at the end of tests groups.
8818 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8819 (AT_data_files, at_data_files): Remove.
8820 (AT_CLEANUP, AT_DATA): Simplify.
8821 (AT_INIT): Adjust.
8822 Remove the group dir if !debug && !failed.
8823 * tests/atspecific.m4: Adjust.
8825 2001-11-13 Akim Demaille <akim@epita.fr>
8827 Start a new layout for Autotest: `testsuite' creates
8828 `testsuite.dir' in which the at-check-line etc. files are to be
8829 found, and `testsuite.dir/003' where the test group 3 is run.
8831 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8832 at_check_line_file, at_format, at_test_normalized, at_group_dir
8833 are new variables.
8834 Create the directories.
8835 Use absolute paths for at- files.
8836 (AT_CHECK): Adjust.
8838 2001-11-11 Michael Matz <matz@kde.org>
8840 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8841 (m4_car2): New.
8842 (m4_car): Properly quote arguments.
8844 2001-11-13 Akim Demaille <akim@epita.fr>
8846 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8847 with stricter rules on LIBOBJS.
8849 2001-11-12 Paul Eggert <eggert@twinsun.com>
8851 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8852 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8853 __PROTOTYPES too.
8855 2001-11-12 Akim Demaille <akim@epita.fr>
8857 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8859 2001-11-12 Akim Demaille <akim@epita.fr>
8861 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8862 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8863 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8864 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8865 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8866 specify to what the macro should be defined (typically to 1).
8868 2001-11-12 Akim Demaille <akim@epita.fr>
8870 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8871 From Jim Meyering.
8873 2001-11-12 Akim Demaille <akim@epita.fr>
8875 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8876 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8877 definition used by Automake where LEX is +/- "${missing} lex" and
8878 `missing' itself contains variables.
8880 2001-11-12 Akim Demaille <akim@epita.fr>
8882 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8883 Now that M4sh pushes BODY, the comments were output at the end of
8884 the test suites.
8886 2001-11-08 Akim Demaille <akim@epita.fr>
8888 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8889 that we can trace macros from aclocal.m4.
8890 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8891 obsoleted, and redirect to the former anyway.
8892 Reported by Ralf Corsepius.
8894 2001-11-08 Akim Demaille <akim@epita.fr>
8896 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be

8911 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8912 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.

8926 From Nicolas Joly.
8928 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8930 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing

8954 * doc/autoconf.texi (autoreconf Invocation): Update.
8956 2001-11-03 Akim Demaille <akim@epita.fr>
8958 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8959 (@export_forward_subs): New.
8960 Add basename, dirname, and fileparse.
8961 (@EXPORT): Adjust.
8962 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8963 Don't look for aclocal flags if we already know aclocal is not
8964 used.
8965 Move aclocal.m4t only if it exists.
8966 Reported by Ezra Peisach.
8968 2001-11-03 Akim Demaille <akim@epita.fr>
8970 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8971 passed on command line, defaulting to ./configure.ac if present.
8972 (&maybe_autoreconf, File::Find): Remove, unused.
8973 (&autoreconf): If autoconf is not used, don't try to trace.
8975 2001-11-02 Akim Demaille <akim@epita.fr>
8977 * configure.ac: Bump to 2.52g.
8979 2001-11-02 Akim Demaille <akim@epita.fr>
8981 Version 2.52f.
8983 2001-11-02 Akim Demaille <akim@epita.fr>
8985 * config/config.guess, config/config.sub, doc/standards.texi:
8986 * config/lispdir.m4: Update from masters.
8987 * configure.ac: Bump to 2.52f.
8989 2001-11-02 Akim Demaille <akim@epita.fr>
8991 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8992 Don't run aclocal when aclocal.m4 is not from aclocal.
8993 From Ezra Peisach.
8994 Don't run libtoolize and gettextize if --install is not given.
8996 2001-11-01 Paul Eggert <eggert@twinsun.com>
8998 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8999 be invoked before _AS_LINENO_PREPARE.
9000 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9001 than character ranges.
9003 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9004 invoking AS_BASENAME. Set the locale variables to 'C' if
9005 possible, as POSIX requires this to get the traditional
9006 behavior.
9007 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9009 2001-10-31 Paul Eggert <eggert@twinsun.com>
9011 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9012 with {}, as that triggers a bug in Bash 2.05.
9014 (_AS_LINENO_PREPARE): Use Sed rather than
9015 Awk. Fix the sed prepass to work even if there are multiple
9016 instances of $LINENO on the same line. Do not substitute for
9017 other variables like $LINENOT. Do not check file dates; such a
9018 check is unreliable on sufficiently fast machines, and removing
9019 the check makes the code simpler and more reliable. Check for
9020 output and chmod failures.
9022 * doc/autoconf.texi (Special Shell Variables): Document
9023 the above.
9025 2001-10-31 Akim Demaille <akim@epita.fr>
9027 * tests/Makefile.am (atconfig): Remove this target, Automake
9028 handles it now.
9030 2001-10-31 Akim Demaille <akim@epita.fr>
9032 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9033 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9034 provided, while it is optional.
9035 * configure.ac: Adjust.
9037 2001-10-26 Paul Eggert <eggert@twinsun.com>
9039 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9040 lib/Autom4te/Struct.pm:
9041 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9042 with 5.005_02.
9044 * doc/autoconf.texi (Special Shell Variables): Document some
9045 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9047 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9048 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9049 eval $LINENO is not portable in practice.
9051 2001-10-24 Akim Demaille <akim@epita.fr>
9053 * lib/Autom4te/General.pm (backname): New.
9055 2001-10-24 Akim Demaille <akim@epita.fr>

9058 * config/: here.
9060 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9062 * doc/autoconf.texi (Shellology): Mention the problems with bash
9063 2.05's use of ANSI quoting in its `set' builtin.
9065 2001-10-22 Paul Eggert <eggert@twinsun.com>
9067 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9068 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9069 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9070 POSIX decided to standardize on the int flavor of strerror_r.
9071 Always do char* test, as there's no reason not to.
9072 Assign to a char* var, to catch strerror_r that returns int*.
9074 * doc/autoconf.texi (Particular Functions):
9075 Document the above changes. Also, document the fact that
9076 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9078 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9080 2001-10-20 Akim Demaille <akim@epita.fr>
9082 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9083 the executable was missing from the log.
9085 2001-10-20 Akim Demaille <akim@epita.fr>
9087 * lib/Autom4te/General.pm (&update_file): If destination is
9088 unchanged, remove the source.
9089 (&up_to_date_p): Don't be verbose, be debug.
9090 * bin/autoreconf.in: No longer support --m4dir.
9091 (&autoreconf): Display the full path of the configure.ac we are
9092 studying.
9093 Trace it only once.
9094 Be sure to honor --force with gettextize.
9095 Always run aclocal.
9096 * doc/autoconf.texi: Adjust.
9098 2001-10-20 Akim Demaille <akim@epita.fr>
9100 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9101 Remove, dead.
9102 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9103 `intl' is already present, as it refuses unless --force.
9104 (&parse_args): Use -I, --include instead of the old Autoconf
9105 options.
9106 ($localdir, $autoconf_dir): Remove.
9107 (@include): New.
9108 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9110 2001-10-19 Jens Petersen <petersen@redhat.com>
9112 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9124 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9125 comment, explain how to install automatic mode selection.
9126 From Russ Allbery.
9128 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9130 * bin/autoreconf.in (autoreconf): Display the path to the
9131 configure.ac being studied.
9133 2001-10-18 Paul Eggert <eggert@twinsun.com>
9135 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9136 long, to work around a bug in the HP C compiler version HP92453-01
9137 B.11.11.23709.GP.
9139 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9140 (AS_BASENAME_EXPR): New macro.
9141 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9142 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9143 and fall back on 'sed' only if the other two fail. This makes
9144 AS_BASENAME act more like AS_DIRNAME.
9145 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9146 contains white space.
9147 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9148 Use AS_DIRNAME, since I think it's now DOS-friendly.
9149 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9150 Allow "dirname //FOO" to return either / or //, as POSIX allows
9151 either behavior.
9153 2001-10-10 Akim Demaille <akim@epita.fr>
9155 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9156 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9157 From Eric Sharkey.

9161 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9291 empty, and if we can find a shell that does support LINENO,
9292 then set CONFIG_SHELL to that shell and then re-execute
9293 ourselves with CONFIG_SHELL.
9295 2001-10-05 Paul Eggert <eggert@twinsun.com>
9297 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9298 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9299 build of $(TESTSUITE).
9301 2001-10-05 Akim Demaille <akim@epita.fr>

9368 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
9369 Don't use nested parenthesization. This patch was originally
9370 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
9371 but somehow it didn't get incorporated then.
9372 * doc/autoconf.texi (Limitations of Usual Tools):
9373 Clarify remark about sed and nested parenthesization.
9375 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
9376 Report an error if the size cannot be determined even though
9377 the type exists.
9378 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9379 Check for `expr' arithmetic overflow, and for compilation failure,
9380 and invoke a new argument $4 if either is discovered.
9381 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9382 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9384 2001-09-28 Akim Demaille <akim@epita.fr>
9386 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

9401 generates too many bug reports.
9403 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
9404 status when executing the ACTION-IF-FALSE.
9405 * tests/base.at (AC_TRY_*): Rename as...

9415 (AC_PROG_CPP requires AC_PROG_CC): here and...
9416 * tests/fortran.at (GNU Fortran 77): there.
9417 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9418 AC_TRY_RUN is about compilation, not shell commands.
9419 (Test Programs): AC_TRY_RUN works as used to be advertised.
9421 2001-09-27 Akim Demaille <akim@epita.fr>
9423 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9424 Raja R Harinath:
9425 Be sure to detect when $LINENO always returns the same value.
9426 Look for the original script, basename($0) is certainly not
9427 enough.
9428 Pass the CLI arguments to `$as_me.lineno'.
9430 2001-09-25 Akim Demaille <akim@epita.fr>
9432 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
9433 Be sure the close and reopen the LOG fd before and after using tee
9434 to extend the log.

9437 2001-09-23 Akim Demaille <akim@epita.fr>
9439 * bin/autom4te.in (parse_args): There can be several invocations
9440 of --language now.
9442 2001-09-23 Akim Demaille <akim@epita.fr>
9444 * doc/autoconf.texi (Top): Wrap in @ifnottex.
9446 2001-09-23 Akim Demaille <akim@epita.fr>
9448 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
9449 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
9450 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
9451 builddir, buildpath, top_builddir, and top_buildpath.
9452 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
9453 the current directory.
9454 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
9455 variables *before* changing the current directory.
9456 Skip nonexistent dirs.
9457 * doc/autoconf.texi (Preset Output Variables): Document these
9458 variables.
9460 * lib/autotest/general.m4: Do not reset AT_victims.
9461 Don't compute at_srcdir nor at_top_srcdir.
9463 * tests/tools.at: Hence use top_srcdir.
9465 * tests/Makefile.am, tests/autoconf, tests/autoheader,
9466 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
9467 Remove.

9470 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
9471 * configure.ac: Build the position independent wrappers.

9478 * doc/autoconf.texi (Common Shell Constructs): Rename as...
9479 (Programming in M4sh): this.
9480 Promote to @section.
9482 2001-09-23 Akim Demaille <akim@epita.fr>
9484 * lib/autotest/general.m4 (AT_INIT): Dump config.log last.

9496 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix shell
9497 over-escaping.

9507 (Autoconf): Adjust.
9509 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
9511 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,
9512 * m4/install-sh.m4, m4/missing.m4, m4/sanity.m4, m4/strip.m4: Updated
9513 to match current versions from CVS Automake.
9515 2001-09-23 Alexandre Duret-Lutz <duret_g@epita.fr>

9518 for $LINENO.
9520 2001-09-22 Akim Demaille <akim@epita.fr>
9522 * lib/autoconf/autotest.m4: Create `package.m4'.
9523 * tests/Makefile.am (package.m4): Remove.
9525 2001-09-22 Akim Demaille <akim@epita.fr>
9527 Rely on `$LINENO' when possible instead of `__oline__'.
9529 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
9530 `$LINENO' support replacement when not supported.
9531 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
9532 them explicitly to be sure they are not output before this section
9533 (via m4_require). Cosmetic only.
9534 * lib/autoconf/c.m4, lib/autoconf/general.m4,
9535 * lib/autoconf/programs.m4: Replace all the occurrences of
9536 `__oline__' with `$LINENO'.
9537 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
9539 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
9541 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
9542 character (u: -> ue) in a code comment.
9543 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
9544 it works.
9546 2001-09-21 Akim Demaille <akim@epita.fr>
9548 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9549 Suggested by Jim Meyering.
9551 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9553 * lib/autoconf/programs.m4: Use extensions listed in
9554 $ac_executable_extensions when looking for programs.
9556 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9558 * lib/autoconf/general.m4: Fix a small Englisho.

9560 setting up ac_dir_suffix and ac_top_builddir.
9561 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
9563 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9565 * doc/autoconf.texi (File System Conventions): Clarify the use of
9566 PATH_SEPARATOR.
9567 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9568 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9569 be used instead of ':'.
9570 * lib/autotest/general.m4: Replace occurrences of ':' in
9571 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9573 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9576 arguments. Fixed a typo.
9578 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9580 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9581 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9583 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9585 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
9586 * bin/autoupdate.in: Ditto.
9587 * bin/autoheader.in: Reworded a few comments.

9592 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9594 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9595 already have $file). Set output files to binary mode (helps avoid
9596 CR issues on DOSish systems).
9598 2001-09-19 Akim Demaille <akim@epita.fr>
9600 * lib/autotest/general.m4: Englishoes.
9601 From Tim Van Holder and Alexey Mahotkin.
9603 2001-09-18 Paul Eggert <eggert@twinsun.com>
9605 * doc/autoconf.texi (Common Shell Constructs): New node,
9606 documenting AS_DIRNAME.
9607 (Limitations of Usual Tools): Refer to it when discussing dirname.
9608 Also, update discussion of POSIX standard to reflect latest draft.
9610 * lib/autoconf/c.m4:
9611 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9613 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9614 Do not pass a first argument with leading '-'
9615 to expr, by parenthesizing initial integers that might be negative.
9617 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9618 now merely checks whether it is an error to pass an argument
9619 to getpgrp.
9621 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9622 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9623 whether it is a (compile-time) error to pass an argument to
9624 getpgrp. This simpler test supports the revised documentation,
9625 and is all that AC_FUNC_GETPGRP's users really need.
9627 2001-09-18 Akim Demaille <akim@epita.fr>
9629 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9631 2001-09-18 Akim Demaille <akim@epita.fr>

9637 2001-09-18 Paul Wagland <paul@wagland.net>
9639 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9640 correctly.
9641 Add test for AS_BASENAME.
9642 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9643 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9644 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9645 * tests/base.at: Fixed the expected responses. The old ones were
9646 one line out...
9647 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9648 the documentation claims it should (and how it behaved in 2.13).
9650 2001-09-18 Akim Demaille <akim@epita.fr>
9652 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9653 the AC_CONFIG_COMMANDS invocation.
9654 This also solves the name clash problems.
9655 Don't set the package's ID.
9656 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9657 No longer to be shipped.
9658 (version.in): Remove.
9659 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9660 * lib/autoconf/status.m4: Adjust.
9661 Use `m4_PACKAGE_STRING'.
9662 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9663 the only optional argument is the name of the test suite.
9664 Expect `package.m4' to define the package signature.
9665 * lib/autom4te.in (Autotest): Add `package.m4?'.
9666 * tests/Makefile.am (package.m4): New.
9667 * tests/suite.at: ifnames is a victim.
9669 2001-09-18 Akim Demaille <akim@epita.fr>
9671 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9672 AC_LIBSOURCE, AC_CONFIG_FILES.
9673 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9674 program version string doesn't match the package's.
9675 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9676 after `(cached)'.
9678 2001-09-17 Paul Eggert <eggert@twinsun.com>
9680 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9681 Allow expression to return any value that can fit into unsigned long
9682 (not int, as before). Check for output errors.
9684 2001-09-17 Bruno Haible <haible@ilog.fr>
9686 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9687 Always include <stdio.h> and <stdlib.h>. Evaluate
9688 the expression in an extra function before these includes. Call
9689 fprintf "%d" only after ensuring the argument is of type 'int'.
9690 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9692 2001-09-17 Paul Eggert <eggert@twinsun.com>
9694 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9695 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9696 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9697 when they don't exist.
9699 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9700 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9701 need it.
9703 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9704 version with the version used by fileutils 4.1, except use
9705 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9706 we don't need it.
9708 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9710 2001-09-13 Akim Demaille <akim@epita.fr>
9712 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
9713 _first_.
9714 Reported by Gerrit P. Haase.
9716 2001-09-13 Akim Demaille <akim@epita.fr>
9718 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9734 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
9735 Likewise.
9736 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
9737 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
9738 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
9739 AT_tests_all for consistency.

9742 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
9744 2001-09-13 Akim Demaille <akim@epita.fr>
9746 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9748 2001-09-13 Akim Demaille <akim@epita.fr>
9750 * lib/autotest/general.m4 (AT_INIT): Create and remove
9751 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9752 test suites can cohabit.
9754 2001-09-13 Akim Demaille <akim@epita.fr>
9756 * tests/mktests.sh: Don't output banners for empty test files.
9758 2001-09-13 Akim Demaille <akim@epita.fr>
9760 Test suites can be run independently of configure.
9762 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
9763 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

9777 (Syntax of the Perl scripts): Check ifnames.
9778 * tests/ifnames: New.
9780 2001-09-13 Akim Demaille <akim@epita.fr>
9782 * lib/autotest/general.m4 (AT_INIT): Let --keywords also match
9783 test group titles.
9784 * tests/atspecific.m4 (AT_CHECK_AU_MACRO): AT_KEYWORDS(autoupdate).

9802 (m4_list_append): Remove.
9804 Spread a few keywords in the Autoconf test suite.
9806 2001-09-10 Akim Demaille <akim@epita.fr>
9808 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
9809 PATH_SEPARATOR, let M4sh compute it.
9810 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
9811 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.
9812 Move to...

9824 2001-09-07 Akim Demaille <akim@epita.fr>
9826 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
9827 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
9828 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
9829 related variables into `at_package_*'.
9830 * lib/autotest/general.m4 (AT_VICTIMS): New.
9831 (AT_INIT): Adjust for stand-alone/embedded test suites.
9832 (AS_MESSAGE_LOG_FD): Define and use it.

9835 at_version.
9837 2001-09-07 Akim Demaille <akim@epita.fr>
9839 Move toward possibly stand-alone test suites.
9841 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
9842 in addition, it introduces useless differences in logs.
9843 (AT_INIT): Let atconfig and atlocal be both optional.
9844 Adjust PATH computation.
9845 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
9847 2001-09-07 Akim Demaille <akim@epita.fr>
9849 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon

9854 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'
9855 to avoid GCC warnings.
9856 From Uwe Seimet.
9858 2001-09-05 Akim Demaille <akim@epita.fr>
9860 * bin/autom4te.in: --language is -l, not -s.
9862 2001-09-05 Akim Demaille <akim@epita.fr>
9864 Be ready to handle filenames as stupid as `dnl.at', for if even
9865 the maintainer is dumb enough to do that...
9867 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9868 excellence in M4 quotation: consider `__file__' is active.
9870 And BTW, when invoking m4, pass the --include in the right order:
9871 the wrong one.
9873 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
9874 4m.
9876 2001-09-05 Akim Demaille <akim@epita.fr>
9878 * lib/Autom4te/XFile.pm: New lib file.
9879 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
9880 * bin/autoheader.in: Use it.
9882 2001-09-05 Akim Demaille <akim@epita.fr>
9884 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
9885 defined.

9890 * bin/autoheader.in, bin/autoupdate.in (&parse_args): Adjust.

9893 Add -I, --include support.
9894 * doc/autoconf.texi (autoscan Invocation): Adjust.
9896 2001-09-05 Akim Demaille <akim@epita.fr>
9898 CVS GNU M4 doesn't like `undefine(undefined)'.
9900 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
9901 New, extracted from main.
9902 Use IO::File wherever possible.
9903 (input.m4): Be constant, use -I instead of hard coding $tmp.
9904 Therefore be a quoted heredoc.
9905 Don't invoke `_au_disable', since ac was not loaded, but just
9906 `unm4.m4'.
9908 2001-08-31 Akim Demaille <akim@epita.fr>
9910 Version 2.52d.
9912 2001-08-31 Akim Demaille <akim@epita.fr>
9914 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
9915 previous patch.

9918 2001-08-31 Akim Demaille <akim@epita.fr>
9920 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
9921 serious problems handling heredocs in heredocs.
9922 Reported by Nicolas Joly.
9924 2001-08-31 Akim Demaille <akim@epita.fr>
9926 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
9927 (Making testsuite Scripts): Update.
9929 2001-08-31 Akim Demaille <akim@epita.fr>
9931 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
9933 2001-08-31 Akim Demaille <akim@epita.fr>
9935 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9936 (testsuite Scripts): There is no such thing as `atconfig.in'.
9937 And actually one diagram is missing: test suite runtime.
9939 2001-08-31 Akim Demaille <akim@epita.fr>
9941 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9942 inverse order.
9944 2001-08-31 Akim Demaille <akim@epita.fr>
9946 * bin/autoupdate.in (@include): `installcheck' revealed the path
9947 to m4sugar was lacking!
9949 2001-08-31 Akim Demaille <akim@epita.fr>
9951 * man/Makefile.am (.x.1): We really have to pass
9952 autom4te_perllibdir.
9954 2001-08-31 Akim Demaille <akim@epita.fr>
9956 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9957 debug scripts, in particular passing explicitly listed tests to
9958 run is stupid.
9960 2001-08-31 Akim Demaille <akim@epita.fr>
9962 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9963 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9964 Use directly autom4te, not autoconf.
9965 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
9967 2001-08-31 Akim Demaille <akim@epita.fr>
9969 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
9970 * bin/autoheader.in (%symbol): Strip arguments of macros.

9976 2001-08-31 Akim Demaille <akim@epita.fr>
9978 * bin/autom4te.in (&parse_args): Die on unknown languages.
9979 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
9980 need for autoconf.
9981 Promote --include over --macrodir and other obsolete options.
9983 2001-08-31 Akim Demaille <akim@epita.fr>
9985 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
9986 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
9987 * bin/autom4te.in ($autoconf): Pass --force.
9988 `print $out' doesn't print `$_' but `$out'.
9989 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9990 (autoheader): Pass --force since the test suite goes too fast for
9991 the time stamps.
9992 Adjust to the new autoheader messages.
9994 2001-08-31 Akim Demaille <akim@epita.fr>
9996 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
9997 Check the completeness of the #template.
9998 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
9999 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
10000 invocation.

10004 * lib/Autom4te/General.pm (&find_file, &update_file): New.
10005 * bin/autoupdate.in, bin/autoheader.in: Adjust.
10006 Drop AC_MACRODIR dead for real.
10007 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10008 `autoheader: `config.hin' is created'.
10009 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10011 2001-08-31 Akim Demaille <akim@epita.fr>
10013 * bin/autoheader.in: Rewrite in Perl.
10014 * tests/autoheader: Adjust.
10016 2001-08-31 Akim Demaille <akim@epita.fr>
10018 * bin/autoconf.in (--include, -I): New option.
10019 Map --localdir, --autoconf-dir onto it.
10020 Forward autom4te's options instead of interpreting them.
10021 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10022 There is no such envvar since the inception of autom4te.cfg.
10023 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10024 * bin/autoupdate.in: Adjust, and perform more control.
10025 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
10026 * tests/autoconf: Dittowise.
10028 2001-08-31 Akim Demaille <akim@epita.fr>
10030 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10031 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10032 optionally `FILE'.
10033 Use -e, not -f, since /dev/null for instance is OK.
10034 (&parse_args): Adjust.
10035 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10037 2001-08-31 Akim Demaille <akim@epita.fr>
10039 * configure.ac: Also find tested executables in bin.
10040 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10041 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10042 installed peer executables, only PATH is allowed to resolve it.
10043 Pass `autoconf_dir' via options, not via invisible envvars.
10044 * lib/Autom4te/General.pm (&find_peer): Remove.
10045 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10046 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10047 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10048 find the executables for it.
10049 * tests/Makefile.am: Major cleanup. Too lazy to document...
10050 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10051 We only need PERL.
10052 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10053 indeed related to running the test suite, while passing
10054 --autoconf-dir and others is related to running non installed
10055 Autoconf executables. So don't do that, leave it to...
10056 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10057 * tests/autoscan: New.
10058 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10059 refer to library files: rely on --language.
10061 2001-08-29 Akim Demaille <akim@epita.fr>
10063 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
10064 s/--set/--language/.
10066 2001-08-29 Akim Demaille <akim@epita.fr>
10068 * doc/autoconf.texi: Strip the @nodes.
10069 Suggested by Paul Eggert.
10070 (Initializing configure): Typo.
10072 2001-08-29 Akim Demaille <akim@epita.fr>
10074 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10075 Suggested by Paul Eggert.
10077 2001-08-29 Akim Demaille <akim@epita.fr>
10079 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10080 download in a tmp dir.
10082 2001-08-29 Akim Demaille <akim@epita.fr>
10084 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10085 case insensitive OSes out there :(
10086 From Tim Van Holder.
10088 2001-08-29 Akim Demaille <akim@epita.fr>
10090 * lib/autom4te.in: New.
10091 * lib/Makefile.am (edit, autom4te.cfg): New.
10092 * bin/autom4te.in (BEGIN): Simplify.
10093 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
10094 (&load_configuration): New. Use it.
10095 (&parse_args): Support --mode, --set, and --melt.
10096 * bin/autoconf.in: Simplify and adjust.
10097 * tests/Makefile.am (AUTOMAKE): Use --set.
10098 * tests/atlocal.in: Adjust.
10099 * BUGS: distcheck and check are weak.
10101 2001-08-29 Akim Demaille <akim@epita.fr>
10103 * lib/autotest/general.m4: Use
10104 foo=`(command) 2>/dev/null`
10105 not
10106 foo=`command` 2>/dev/null
10107 (at-devnull): Rename as...
10108 (AT-devnull): this.
10109 (--clean): Remove AT-* files too.
10110 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10111 Reported by Nicolas Joly.
10113 2001-08-28 Akim Demaille <akim@epita.fr>
10115 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

10121 * doc/autoconf.texi (Function Portability): Mention C right shifts.
10123 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
10125 * lib/autotest/general.m4: Reword some messages.
10126 (AT_INIT): Check for the `times' builtin before using it.
10127 Support test ranges as arguments to the testsuite.
10128 Have -e imply -d as the help text suggested.
10130 2001-08-27 Akim Demaille <akim@epita.fr>
10132 * Makefile.maint: Formatting changes.
10133 (do-po-update, po-update, cvs-update, update): New targets.

10138 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

10145 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10146 Support `VAR=VAL' as arguments.
10147 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
10148 may be set via the command line.
10150 2001-08-27 Akim Demaille <akim@epita.fr>
10152 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
10153 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
10154 first the build dirs, then the src dirs.

10166 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
10167 `ac_top_builddir' to mimic Automake's vocabulary, which much more
10168 readable.
10169 Adjust callers.
10170 * doc/autoconf.texi (Configuration Actions): Document the vars
10171 available in commands.
10172 Emphasize the risks of collisions in init-cmds.

10177 (Initializing configure): this new node.
10179 2001-08-27 Akim Demaille <akim@epita.fr>

10192 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

10202 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
10203 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
10204 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
10205 -> ac_dir).
10206 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
10207 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
10209 2001-08-27 Akim Demaille <akim@epita.fr>

10234 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
10235 (AMTAR): Help automake define it.
10236 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
10237 needed, 1.5 can have a macro and a target with the same name.
10238 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
10239 * m4/strip.m4: New.

10252 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
10253 Adjust callers.
10254 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10255 the name of the directory they're in, instead of the filename,
10256 since version.m4 is now in m4sugar, but m4_acversion must not be
10257 classified as an Autoconf macro.
10258 ($input_m4): Don't qualify the path to m4sugar.
10259 Rather, pass autoconf_dir to m4.
10260 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
10261 * tests/suite.at: Require 2.52c.
10263 2001-08-27 Akim Demaille <akim@epita.fr>

10275 of config.log on traps.
10276 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
10277 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
10278 for config.status'.
10279 Open the log as soon as possible.

10345 * NEWS, README, README-alpha, TODO, tests/README: This package is
10346 `Autoconf', not `autoconf' (the executable).
10348 2001-08-20 Akim Demaille <akim@epita.fr>
10350 Info readers seem to need `Index' in the index node title :(
10352 * doc/autoconf.texi: Reverse the 2001-08-15 change which
10353 simplified index node names.

10397 2001-08-20 Akim Demaille <akim@epita.fr>
10399 Huh!?!?! There are still some user EOF tags used, which prevents
10400 their use in AC_CONFIG_COMMANDS for instance...
10402 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
10403 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

10466 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
10467 `$0.log' as for projects where testsuite is in src, we'd have
10468 testsuite.log created in src.

10472 * bin/autom4te.in (&parse_args): Recognize --normalize.

10482 2001-08-17 Akim Demaille <akim@epita.fr>
10484 * doc/autoconf.texi: Work around Texinfo buglets.
10485 (Transformation Rules): One example is enough, users are expected
10486 to have their brains on. And BTW, use DESTDIR.
10487 (dvar): New macro. Use it.
10489 2001-08-17 Akim Demaille <akim@epita.fr>
10491 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

10497 * bin/autom4te.in: --normalize is a new option.
10498 * bin/autoconf.in: Use it.

10524 * doc/install.texi: Use @command.

10528 2001-08-15 Akim Demaille <akim@epita.fr>

10531 value.
10532 From Kevin Ryde.
10534 2001-08-15 Akim Demaille <akim@epita.fr>
10536 * Makefile.maint (CVS): New.
10537 (local-check): Run changelog-check. last.
10538 (alpha): Don't depend upon local-check, since...
10539 (cvs-dist): depends upon it.
10541 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
10543 * tests/Makefile.am: Use a clean-local rule to remove
10544 autom4te.cache (it's a directory, not a file.
10545 * Makefile.am: Ditto (but maintainer-clean-local).
10547 2001-08-15 Akim Demaille <akim@epita.fr>
10549 * bin/autom4te.in (@m4_warning): New.
10550 (&handle_m4): Use it.
10551 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10552 warnings are issued at each run.
10553 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10554 is in the src tree.
10556 2001-08-15 Akim Demaille <akim@epita.fr>
10558 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
10559 don't waste time running `autoupdate --version' works.
10560 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10562 2001-08-13 Akim Demaille <akim@epita.fr>
10564 * doc/autoconf.texi (ma): Rename this index as...
10565 (ac): this.
10567 2001-08-13 Akim Demaille <akim@epita.fr>

10577 * lib/autotest/general.m4 (AT_INIT): Log the start/stop dates and
10578 duration of the test suite.
10580 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
10582 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
10583 endianness for comparison instead of relying on AT_CHECK_ENV.
10585 2001-08-11 Paul Eggert <eggert@twinsun.com>
10587 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
10588 to the INSTALL file.
10590 2001-08-11 Paul Eggert <eggert@twinsun.com>

10615 * tests/mktests.sh: Update year in copyright notice.
10617 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
10619 * tests/semantics.at (AC_C_BIGENDIAN): New test.
10621 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10623 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10624 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10625 * doc/autoconf.texi (C Compiler Characteristics): Update
10626 documentation for AC_C_BIGENDIAN.
10628 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10630 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10631 magic values from an object file when cross-compiling.
10632 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10634 2001-08-10 Akim Demaille <akim@epita.fr>
10636 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10637 effects.
10638 Suggested by Russ Allbery.
10640 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10642 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10643 current $prefix to the sub-configures.
10645 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10647 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10648 extension (needed on BeOS). Reported by Guido van Rossum.
10650 2001-08-09 Akim Demaille <akim@epita.fr>
10652 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10654 2001-08-07 Akim Demaille <akim@epita.fr>
10656 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10657 removed.
10658 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10659 No need to remove the files before and after the each test, before
10660 each test and at the end of the suite is enough.
10661 Display only the children `times', not the shell's.
10662 If the test failed or was skipped, at-times is not available.
10664 2001-08-07 Akim Demaille <akim@epita.fr>
10666 Always produce testsuite.log, including when there are no
10667 failures. This helps getting information on skipped tests, and
10668 duration of the tests. Err, implement the latter btw.
10670 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10671 Dump information on the first run of each test.
10672 (AT_CLEANUP): Create `at-times' containing the duration of the
10673 test group.
10675 2001-08-07 Akim Demaille <akim@epita.fr>
10677 The use of `dumpstat' revealed that `len' was used although it
10678 should not. m4_text_wrap was using it, but in the Autoconf world
10679 where it is legal. Hence (i) test M4sh in its own world, not
10680 Autoconf's, and (ii), ahem, fix the bug :)
10682 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10683 does not like `' instead of [].
10684 (AT_INIT): Forbid `^_?AT_'.
10685 And don't output such tokens.
10686 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10687 `script.as', and `autom4te.cache'.
10688 Remove `empty' and `macro' which are no longer used.
10689 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10690 * tests/m4sugar.at: Use it.
10691 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10693 2001-08-07 Akim Demaille <akim@epita.fr>
10695 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10697 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10699 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10701 2001-08-04 Akim Demaille <akim@epita.fr>
10703 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10704 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10705 AC_TRY_LINK.
10706 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10707 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10708 (AC_F77_MAIN): Likewise.
10710 2001-08-04 Akim Demaille <akim@epita.fr>
10712 Don't rely on M4sugar outputting the patterns in files, since we
10713 might process the output _without_ running m4, hence without these
10714 files.
10716 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10717 * bin/autom4te.in (@Request::includes): Remove, unused.
10718 (@Request::source): Rename as...
10719 (@Request::input): this.
10720 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10721 (&handle_output): Fetch the patterns from the traces.
10722 `$forbidden' and `$allowed' are constant: use m//o.
10723 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10724 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10726 2001-08-04 Akim Demaille <akim@epita.fr>
10728 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10729 autoconf', i.e., in addition to caching traces, cache the output.
10731 * bin/autom4te.in (Request::cache): Rename as...
