3 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
4 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
5 Bill Northcott in
6 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
8 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
10 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
11 pacify insanely picky compilers. Problem reported by Eric Blake.
13 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
14 longer supported by Sun.
16 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
18 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
19 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
20 -Wundef -Werror". Problem reported by David Fang in
21 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
22 * doc/autoconf.texi (Header Templates, Default Includes):
23 (Particular Functions, Generic Functions, Header Portability):
24 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
25 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):
26 (Present But Cannot Be Compiled, Preprocessor Symbol Index):
27 Prefer #ifdef to #if.
28 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prefer #ifdef to #if.
29 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, _AC_FUNC_MALLOC_IF):
30 (AC_FUNC_MKTIME, AC_FUNC_MMAP, _AC_FUNC_REALLOC_IF):
31 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETVBUF_REVERSED, _AC_FUNC_VFORK):
32 Likewise.

36 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
37 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
38 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
39 this.
41 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
43 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
44 problems with arg script text that doesn't end in newline, and
45 with '-e a...'. Problems reported by Ralf Wildenhues.
47 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
49 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

55 to last change.
57 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
59 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
60 --help' should mention that `--version' outputs configuration
61 settings. Report by Bruno Haible.
63 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
65 Fix test suite failures reported by Pierre in
66 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
67 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
68 the compiler created a file "b.out" when it didn't create anything
69 at all.
70 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
71 Discard stderr too, when invoking the test script.
73 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)

84 leading white space from text. From Bruno Haible.
86 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
88 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
89 compiler complains about it, even if things works after the
90 complaint. Problem reported by Peter O'Gorman.
92 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
93 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
94 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
96 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
98 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
99 after -R regardless of host. Patrick Welche reports that this
100 fixes things on NetBSD 3.99.
102 * NEWS: Recommend M4 1.4.5.
103 * README: Likewise.
104 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
105 * tests/tools.at (autom4te cache): Update wording of diagnostic
106 to match M4 1.4.5.
108 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
110 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
111 under AC_C_VOLATILE.
112 (Volatile Objects): Be a little less skeptical about what
113 "volatile" means. Derived from thoughts by Ben Pfaff in
114 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
116 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
118 * doc/autoconf.texi: Fix some typos.
120 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
122 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
123 more globally, since the 2006-06-30 patch didn't suffice. Problem
124 reported by Keith Marshall. Also, don't bother with builddir2,
125 since it shouldn't be needed any more.
127 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
129 * doc/autoconf.texi (Generic compiler characteristics):
130 Document AC_COMPUTE_INT. Fix wrong statements on Default
131 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
133 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
134 (_AC_COMPUTE_INT): Add obsoletion warnings.
135 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
136 AC_COMPUTE_INT.
138 * NEWS: Document change.
140 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
142 * doc/autoconf.texi (Volatile Objects): New section.
144 * NEWS: Document previous change.
146 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
148 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
149 Require that long long int be at least 64 bits wide. C99 requires
150 this and enough programs depend on it so we should check for it.
151 Bruno Haible reports in
152 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
153 that long long int is 32 bits wide with some nonstandard compilers.
154 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
156 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
158 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
159 to a nonexistent file, so that we don't have to worry about
160 a local site configuration that doesn't use /usr/local.
161 Problem reported by Keith Marshall in
162 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
164 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
166 * doc/autoconf.texi: Be more consistent about using @acronym with
167 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
168 quite right (it talked about "OSF/Tru64", even though the
169 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
170 and it even mentioned "OSF 4"!) and at this point there's little
171 reason to talk about OSF any more, since it died in 1994.
172 (Specific Compiler Characteristics): Simplify example of
173 negative-size array.
174 (File Descriptors): Reorder to make the text flow better.
175 Remove joke about "appreciate the various levels"; I didn't get it.
176 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
177 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
178 (File Descriptors, Limitations of Usual Tools):
179 Tone down the advice against renaming or removing open files.
180 (Limitations of Usual Tools): Add a new section, on 'rm'.
182 2006-06-26 Stepan Kasal <kasal@ucw.cz>
184 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
185 -lXt in LIBS, idea from Karsten Hopp; this was due since
186 this change:
188 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
189 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
190 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
191 (which belong to Xt, not X itself). See Debian bug 327655.
193 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
195 * configure.ac (AC_INIT): Bump to 2.60a.
196 * NEWS: Update.
198 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
200 Version 2.60.
202 * configure.ac, NEWS: Update.
204 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
206 * config/texinfo.tex: Sync from upstream.
208 * bin/autom4te.in (handle_traces): Transform the `@S|@'
209 quadrigraph correctly in traces.
211 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
212 Fix typos.
214 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
215 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
216 not defined.
217 * doc/autoconf.texi (Changed Directory Variables): New node,
218 to document the whole `datarootdir' business a bit better.
219 * NEWS: Update.
220 * tests/torture.at (datarootdir workaround): Extend test.
221 Prompted by report by Alexandre Julliard.
223 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
225 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
226 when using default mode of IBM C 6 for AIX. Problem and two-line
227 fix reported by Larry Jones.
229 2006-06-22 Alexandre Julliard <julliard@winehq.org>
231 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
232 about literal '${datarootdir}' if a definition is found in the
233 output file.
235 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
237 * NEWS: Use "M4" rather than "m4" when appropriate.
238 Problem reported by Eric Blake.
239 * doc/autoconf.texi: Likewise.
240 Use @acronym around BSD, GCC, and GNU when appropriate.
241 (Why GNU M4): Renamed from "Why GNU m4".
242 (Redefined M4 Macros): Mention that Posix
243 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
244 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
245 to int.
247 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
249 * bin/autom4te.in (handle_output): Do not forbid the empty
250 pattern.
251 * tests/tools.at (autoconf: the empty token): New test.
253 2006-06-20 Stepan Kasal <kasal@ucw.cz>
255 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
256 calls, so that we do not care whether they are LIFO or FIFO;
257 in the m4_wrap, do not check which diversion is the topmost
258 one, just check that the stack is balanced at the end.
259 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
260 base diversion forever--pop the previous diversion before
261 opening the new one; consequently, remove the m4_wrap call.
262 * lib/autotest/general.m4 (AT_INIT): Likewise.
263 * tests/m4sugar.at: Do not use
264 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
266 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
267 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
269 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
270 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
271 Rework example of m4wrap token-pasting trouble so that it doesn't
272 care whether it's LIFO or FIFO.
273 Fix some "contrary to"s that are awkward in English.
275 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
277 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
278 to `yes' instead of `int$1_t' if the type is found, for more
279 consistent configure output (where $1 is the number of bits).
280 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
281 Suggested by Bruno Haible.
283 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
284 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
285 with system headers. Report by Bruno Haible.
287 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
289 * config/config.guess, config/config.sub: Sync from upstream.
291 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
292 in order to avoid picking up an older installed frozen m4sh.m4f.
293 Besides an outdated shell startup, this could have been created
294 by an earlier M4 version with incompatible frozen file format.
296 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
298 * README: Recommend m4 1.4.4 instead of 1.4.3..
299 * doc/autoconf.texi: Likewise.
300 (Special Chars in Names): Say that $(.FOO) is portable, as
301 suggested by Stepan Kasal.
302 (Installation Directory Variables, Build Directories):
303 (Automatic Remaking, Subdirectories, Fortran Compiler):
304 (Making testsuite Scripts, Defining Directories):
305 Quote variable usages better.
306 (Making testsuite Scripts): Add clean-local rule to makefile
307 snippet, by Eric Blake.
308 (Installation Directory Variables): Fix table item font.
309 Reword slightly to clarify. Generalize advice about
310 not using special characters to include all file-related
311 vars, not just VPATH.
312 (Special Chars in Variables): Warn about special characters in
313 $(srcdir) too.
314 (Assignments): Clarify default-value example as suggested by
315 Ralf Wildenhues in
316 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
317 (Special Shell Variables): Note leading ./ or ../, as suggested
318 by Eric Blake.
319 (Limitations of Builtins): Under cd, warn about CDPATH.
320 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
321 Ralf Wildenhues.
323 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
325 * doc/autoconf.texi (Configuration Actions): Remove duplicate
326 `@var', for texi2html.
327 (Systemology): Some more word wrapping, for DVI output.
328 (autom4te Invocation): The short option for `--melt' is `-M',
329 not `-m'.
331 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
333 * doc/autoconf.texi: More formatting and English tweaks,
334 many suggested by Ralf Wildenhues.
335 Reword to avoid "@code{...}'s" and the like, since it's ugly
336 with Emacs info mode. discontents -> woes.
337 Put a few "will"s back. time stamp -> timestamp.
338 side-effect -> side effect.
340 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
342 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
343 Warn about $@ not persisting. Problem reported by Julien Danjou in
344 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
345 (Special Chars in Names): Renamed from Leading _ in Macro Names.
346 Mention other special chars, too.
348 2006-06-14 Eric Blake <ebb9@byu.net>
350 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
352 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
354 * doc/autoconf.texi: Some systematic minor improvements, as
355 follows. Use "makefile" when talking about makefiles
356 generally (which might be named "makefile" or "Makefile" or even
357 "foo.mk"), "Makefile" when talking about a specific makefile
358 called "Makefile". This unclutters the text from weird quotes
359 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
360 values" rather than "@var{foo}s" and similar constructs containing
361 "}s". Use "Make rules" rather than "Makefile rules". Minor
362 English-language improvements. Change the prefix "sub-" to "sub"
363 and "re-" to "re".
364 Put blank lines around examples more consistently.
365 Avoid "rather" and "very" as intensifiers.
366 Avoid "will" as an auxiliary.
367 (Limitations of Make): Split this node into....
368 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
369 (Leading _ in Macro Names, Backslash-Newline-Newline):
370 (Backslash-Newline Comments, Long Lines in Makefiles):
371 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
372 (obj/ and Make, make -k Status, VPATH and Make):
373 (VPATH and Double-colon, $< in Explicit Rules):
374 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
375 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
376 New nodes, resulting from splitup of Limitations of Make.
377 All cross-references changed. Raise the top node from
378 a section to a chapter, and all subnodes accordingly.
379 Redo the introductory wording to match the new organization.
380 (Installation Directory Variables): Use an example that is
381 closer to what Autoconf actually does. Mention that VPATH's
382 value should not contain metacharacters or white space.
383 (Fortran Compiler): Fix a VPATH bug in an example.
384 (Leading _ in Macro Names): Mention that this problem is no longer
385 of practical concern.
386 (VPATH and Make): Reword the advice to make it clearer
387 that Autoconf and Automake support VPATH in non-GNU make, but
388 many packages have bugs in this area.
389 ($< in Explicit Rules): Refer to Build Directories rather
390 than using a (non-VPATH-safe) example.
391 (Automatic Rule Rewriting): Mention the sort of disaster that
392 can ensue with Solaris-style rule rewriting with VPATH.
394 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
396 * doc/install.texi (Compilers and Options): Weaken the
397 suggestion to use GNU make for VPATH builds.
399 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
400 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
402 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
403 in regular expression.
405 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
407 * doc/autoconf.texi (Installation Directory Variables):
408 Drop extra @samp from `@table @samp' item.
409 (Limitations of Usual Tools): Comment fix.
410 Do not nest @samp just to point to other table items.
411 (Writing testsuite.at) <AT_CHECK>: The second argument to
412 `@dvar' is already @samp'ed.
413 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
414 do not use @var in the second argument.
416 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
418 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
419 $as_shell.exe too. Problem reported by Andreas Buening in
420 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
422 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
424 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
425 `unused variable' compiler warning, for `-Wall -Werror'.
426 Reported by Jaap Haitsma in
427 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
429 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
431 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
432 case the compiler dumps core. Problem reported for
433 OpenServer 5.0.7 by Tim Rice in
434 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
435 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
436 Likewise.
438 2006-06-06 Tim Rice <tim@multitalents.net>.
440 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
441 "ERROR" only shows up in "make check" output if there is an
442 error.
444 2006-06-06 Eric Blake <ebb9@byu.net>
446 * tests/tools.at (automatically allowed tokens): Fix typo.
448 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
450 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
452 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
453 typically overflows on x86 CPUs, even though the C standard
454 requires otherwise.
456 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
458 * configure.ac (AC_INIT): Bump to 2.59e.
459 * NEWS: Update.
461 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
463 Version 2.59d.
465 * config/texinfo.tex: Sync from upstream.
467 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
468 seen, invoke libtoolize with `--ltdl' argument.
469 * lib/autom4te.in (Autoreconf-preselections): Adjust.
470 * NEWS: Update.
471 Suggested by Eric Blake.
473 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
475 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
476 reported by Ralf Wildenhues.
477 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
479 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

487 2006-06-05 Stepan Kasal <kasal@ucw.cz>
489 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
490 message issued by AC_REQUIRE.
491 * tests/m4sugar.at: Check m4_require's error message.
492 * tests/base.at: Check AC_REQUIRE's error message.
493 * tests/local.at (AT_CHECK_M4): New macro, almost identical
494 to...
495 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
496 AT_CHECK_M4.
497 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
498 `expout' as the last parameter.
499 * tests/tools.at: Adapt to the above change.
501 2006-06-04 Stepan Kasal <kasal@ucw.cz>
503 * doc/autoconf.texi (Limitations of Usual Tools): Correct
504 information about race-free implementations of mkdir.
506 2006-06-04 Eric Blake <ebb9@byu.net>
508 * bin/autoreconf.in (help): Document M4 environment variable.
509 * bin/autoconf.as (Usage): Likewise.
510 * bin/autom4te.in (help): Likewise.
511 * doc/autoconf.texi (autom4te Invocation): Likewise.
513 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
515 * NEWS: GNU make now recommended for VPATH builds.
516 Mention that some macros are now documented to be obsolescent.
517 * doc/autoconf.texi:
518 Prefer "current" to "modern" to describe
519 currently-used (albeit perhaps old-fashioned) hosts.
520 Mention which ancient features no longer need to be worried about.
521 setgid -> set-group-ID
522 setuid -> set-user-ID (these are the Posix terms)
523 Fix some misuses of "only".
524 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
525 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
526 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
527 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
528 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
529 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
530 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
531 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
532 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
533 Mention that these macros are obsolescent.
534 (Installation Directory Variables): shall -> should
535 (File Descriptors): Mention that 0, 1, 2 might get reopened.
536 Mention that it's now safe to use 3 and 4.
537 (Limitations of Usual Tools): cp -r is now specified by Posix.
538 Omit longwinded and obsolescent discussion of cp -f.
539 Modernize discussion of expr, ls.
540 (Limitations of Make): Modernize discussion of VPATH builds.
541 Mention $? as a workaround in some cases.
542 * doc/install.texi (Basic Installation):
543 Mention "./configure; make; make install" first. Be more
544 specific about why this file is generic. Remove unnecessary
545 parens. Remove misleading "only". Remove obsolete advice
546 about csh. Don't say "configure" takes awhile; say it
547 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
548 and CC=c99 rather than CC=c89, as these are blessed by current
549 Posix. Recommend GNU make if doing a VPATH build.
551 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
553 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
554 examples involving shell prompts.
556 2006-06-02 Stepan Kasal <kasal@ucw.cz>
557 and Paul Eggert <eggert@cs.ucla.edu>
559 * doc/autoconf.texi (Here-Documents): Add details about the
560 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
561 use "here-documents" instead of "here documents".
563 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
565 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
567 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
569 * doc/autoconf.texi (File System Conventions): Warn about ":"
570 anywhere in directory names.
572 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
574 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
575 about quoting the case statement, just in case.
576 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
577 was fixed in ksh93g; reported by Ralf Wildenhues.
579 2006-05-31 Stepan Kasal <kasal@ucw.cz>
581 * doc/autoconf.texi (System Services): Do not document
582 overriding EXEEXT via ac_cv_exeext=ext.
583 (Particular Programs) <AC_PROG_MKDIR_P>:
584 Document that ${MKDIR_P} understands --.
585 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
586 comment.
588 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
590 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
591 argument with leading hyphen. Problem reported by Paul Eggert.
593 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
595 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
596 about quoting ac_try: quote all of it, if any of it seems suspicious.
597 This means we don't have to worry about ${ or sed any more.
598 Also, double-quote the case statement, to work around misuses via
599 underquoting as reported by Ralf Wildenhues in
600 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
601 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
602 undocumented and dangerous macro.
603 Problem reported by Ralf Wildenhues in
604 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
606 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
608 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
609 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
610 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
612 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
614 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
615 since evidently some packages rely on the old, broken behavior.
616 Problem reported by Ralf Wildenhues in
617 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
618 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
619 pre-2006-05-26 definitions, but leave in the comments that
620 these macros are dangerous and should not be used.
621 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
622 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
623 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
624 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
625 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
627 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
629 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
630 the use of 'tr', since this is our only use of 'tr'.
632 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
633 and Paul Eggert <eggert@cs.ucla.edu>
635 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
636 Don't assume 'grep' works on long lines, since AIX grep doesn't.
638 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
640 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
641 the output file in the `${datarootdir}' test.
643 2005-05-28 Stepan Kasal <kasal@ucw.cz>
644 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
646 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
647 mention of `datarootdir' in the input file(s), but literal
648 `${datarootdir}' in the output file, and we haven't warned yet,
649 then warn as well: the user may have (erroneously) used
650 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
651 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
652 * tests/torture.at (datarootdir workaround): Extend this test.
653 * NEWS: Update.
655 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
656 and Paul Eggert <eggert@cs.ucla.edu>
658 * doc/autoconf.texi (autoheader Invocation): The first argument to
659 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
660 alternatives and clear up the language a bit.
662 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
664 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
665 ac_config_guess, ac_config_sub, ac_configure.
666 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
667 Fix typo that prevented an unnecessary space from being removed.
668 Problems reported by Ralf Wildenhues in:
669 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
671 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
673 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
674 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
675 Don't use the term "thread-safe" to talk about mkdir race
676 conditions, since the problem is more a process than a thread
677 issue. Problem reported by Stepan Kasal in:
678 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
679 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
680 the test for 'install' more closely. Look at MKDIR_P first.
681 Look in the PATH, and at /opt/sfw/bin.
682 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
683 Don't bother to try mkdir -p, since we already check mkdir --version;
684 just look at the version number. (There's no easy way to check
685 for race-free implementations.)
686 * tests/tools.at (autoconf: subdirectories): Adjust to above
687 changes, since MKDIR_P now might end in "/mkdir -p".
689 * doc/autoconf.texi (autoheader Invocation): Mention that the
690 first arg of AC_DEFINE_UNQUOTED must be a literal.
691 Problem reported by Ben Pfaff in
692 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
694 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
695 * doc/autoconf.texi (Special Chars in Variables): New section.
696 (Preset Output Variables): Warn about special chars in CPPFLAGS.
697 (Installation Directory Variables): Quote $(datadir) better.
698 (Limitations of Builtins): Describe some of eval's trickiness.
700 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
701 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
702 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
703 in front of every arg, not just trailing args. Quote apostrophes.
704 (_AC_EVAL_ECHO): New macro.
705 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
706 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
707 removed.
708 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
709 exposed by quoting of eval argument. Put the command on line line
710 so it logs better.
711 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
712 (_AC_PATH_X, AC_PATH_X): Quote more safely.
713 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
714 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
715 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
716 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
717 Use eval more safely.
718 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
719 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
720 to be replaced.
721 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
722 lines, exposed by quoting of eval argument.
724 2006-05-26 Stepan Kasal <kasal@ucw.cz>
725 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
727 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
728 initialization of `ac_cv_exeext', do not override it if it was
729 already set, unless it was set to `no', for compatibility with
730 Autoconf-2.13, and comment this.
731 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
732 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
733 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
734 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
735 Document that this test may be overridden by setting
736 `ac_cv_exeext'.
738 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
740 Revert these two patches:
742 2006-04-06 Eric Blake <ebb9@byu.net>
743 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
744 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
745 2006-04-01.
747 2006-04-01 Stepan Kasal <kasal@ucw.cz>
748 Clean up _AC_COMPILER_EXEEXT* macros.
749 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
750 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
751 ac_file to the name of the default output file and call
752 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
753 initial `rm' of the candidate files...
754 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
755 the same list in subsequent `rm' calls, and for the temporary
756 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
757 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
758 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
759 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
760 no longer needed) by libtool. Make it a cache check.
761 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
762 copied here by mistake.
763 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
764 _AC_COMPILER_EXEEXT.
765 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
766 _AC_COMPILER_OBJEXT directly.
767 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
769 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
771 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
772 Fix description of how the buggy `sed' works.
774 2006-05-25 Noah Misch <noah@cs.caltech.edu>
776 Sync from Automake:
778 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
779 ENOLCK. Only mention `make -j' when applicable. Only raise
780 fatal errors when `make -j' is involved. Improve error message.
782 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
784 * doc/autoconf.texi (Here-Documents): We now know more about
785 the variable expansion in here documents bug.
786 Thanks to Tim Rice and Stepan Kasal.
788 * doc/autoconf.texi (Making testsuite Scripts): Add an example
789 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
791 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
793 * tests/autotest.at (Multiline command from M4 expansion):
794 No failure to be expected if the shell quotes newlines in
795 commands in the `set -x' output. Report by Tim Rice.
796 * THANKS: Update.
798 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
800 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
801 expansion in the here-documents used by config.status, as that
802 runs afoul of the Korn shell version M-12/28/93d bug described in
803 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
804 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
805 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
807 2006-05-23 Jim Meyering <jim@meyering.net>
809 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
810 Fix typo introduced with 2006-04-02 change. It reversed the sense
811 of the test.
813 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
815 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
816 ac_dB slightly, to save bytes in the script.
817 Max out at 50 lines, rather than 96; this is more likely
818 (though not guaranteed) to avoid obscure 'sed' failures.
820 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
822 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
823 `tr -d -' as bad option argument. Work around this by deleting
824 an unrelated character.
825 Report by Tim Rice <tim@multitalents.net>.
827 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
828 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
829 Stepan Kasal <kasal@ucw.cz>
831 * doc/autoconf.texi (Particular Programs): Do not promise that
832 we always prefer the GNU version of the program, and that we
833 search according to PATH; both rules can have exceptions.
834 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
835 AC_PROG_SED. Move descriptions of limitations
836 to the Limitations of Usual Tools section.
837 (Limitations of Usual Tools) <sed>: Mention script length
838 limitations with Solaris /usr/ucb/sed.
839 <grep>: Fix wording for empty alternative. Mention that -c and
840 -l should not be combined, and that -E and -F should not be
841 combined.
843 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
844 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
846 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
847 limits in Solaris 8 /usr/ucb/sed by testing a long script.
849 2006-05-22 Stepan Kasal <kasal@ucw.cz>
851 * doc/autoconf.texi (Defining Symbols): Literal parameter of
852 AC_DEFINE is now passed to m4_pattern_allow.
853 * NEWS: Mention that; likewise for AC_SUBST.
854 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
855 the parameter to m4_pattern_allow.
856 * tests/tools.at: Add a check for that.
858 2006-05-22 Stepan Kasal <kasal@ucw.cz>
860 * lib/autoconf/status.m4: Fix typos.
862 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
864 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
865 only the files that this macro generates.
867 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
869 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
870 the HP-UX sed limitation of 99 commands, labels do not count.
871 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
872 in the comment.
873 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
875 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
877 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
878 Import the following fix from coreutils:
880 2006-01-13 Jim Meyering <jim@meyering.net>
882 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
883 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
884 not double-quote uses of that variable, to accommodate the rare
885 case in which getmntent is available in none of the libraries
886 checked. This happens at least on FreeBSD 5.0.
888 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
890 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
891 ac_config_guess, ac_config_sub, and ac_configure, since evidently
892 some other programs unwisely rely on these undocumented vars.
893 But put in warning comments about them.
894 Problem reported by Ralf Wildenhues in
895 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
896 * NEWS: Document that these variables are intended to go away.
898 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
900 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
901 and set the language to C++ (analogous to the equivalent Fortran
902 tests).
904 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
905 * doc/autoconf.texi (C++ Compiler): Document it.
906 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
907 * NEWS: Update.
909 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
911 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
912 that caused config.status to generate 100-command sed scripts; the
913 portable limit is 99.
915 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
917 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
918 variable `ac_d' instead of `d' to avoid infringing namespace.
919 Report by Ralf Menzel.
921 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
923 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
924 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
925 * tests/tools.at (autoconf: subdirectories): New test, taken from
926 the corresponding problem report by Ralf Wildenhues in:
927 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
929 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
930 Quote some uses of shell variables if they might suffer unexpected
931 globbing. This doesn't fix all instances of quoting problems that
932 I found, just the easy ones that look safe.
933 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
934 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
935 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
936 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
937 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
938 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
939 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
940 Likewise.
941 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
942 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
944 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
946 * bin/autoreconf.in ($help): Reword according to the manual.
947 Suggested by Olly Betts.
949 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
950 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
952 * bin/autoreconf.in: Pass the directory argument to
953 `require_configure_ac'. Fix comment.
954 * tests/torture.at (Configuring subdirectories): Expose this.
955 Reported by Olly Betts.
957 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
959 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
960 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
961 Automake as follows:
963 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
964 `$configure_in' instead of `configure.in', to preserve
965 directory component.
967 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
969 * config/config.guess, config/config.sub, config/texinfo.tex,
970 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
972 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
974 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
975 test for C99 conformance; (bool) 0.5 is an integer constant
976 expression, but (bool) -0.5 is not. Problem reported by Fedor
977 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
979 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
981 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
982 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
983 Warn about obsolete install-sh files. Remove stray sentence
984 fragment and fix cross reference.
985 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
986 install -d; this undoes the 2006-05-10 change.
987 (MKDIR_P): Mark with AN_MAKEVAR.
988 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
989 that we don't require $INSTALL to be thread-safe. Move comments
990 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
991 of AC_PROG_INSTALL. Output a message saying that we're checking
992 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
993 MKDIR_P instead of AC_SUBST.
994 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
995 Special magic for MKDIR_P, too.
996 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
997 a dnl.
998 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1000 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1002 Sync from Automake, as follows:
1004 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1005 * config/install-sh: Initialize IFS, so field splitting isn't
1006 turned off later.
1007 * config/mkinstalldirs: Likewise.
1008 * config/missing: Remove superfluous quotes. Replace all uses of
1009 `[' by `test', for consistency, and for..
1010 * config/missing (sed_minuso, sed_output): New variables.
1011 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1012 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1013 Fixes `missing' to detect `--output' for help2man. Fixes
1014 PR automake/483. Report by Dennis J. Linse.
1015 (autom4te): Document in `missing --help'.
1017 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1019 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1020 * config/install-sh: Don't use 'path' to talk about file names,
1021 as per GNU coding standards. Close a race condition reported by Ralf
1022 Wildenhues and Stepan Kasal. There is still a race condition
1023 on hosts that predate Posix 1003.1-1992, but we can't help this.
1024 Don't mishandle weird characters like space on pre-Posix hosts.
1025 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1026 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1027 AC_PROG_MKDIR_P from AS_MKDIR_P.
1028 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1029 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1030 earlier editions are not (including Automake 1.8.3).
1031 Do not suggest mkinstalldirs for thread-safety.
1032 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1033 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1034 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1035 presence of special characters and race conditions.
1036 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1037 in Autoconf's name space.
1039 2006-05-10 Bruno Haible <bruno@clisp.org>
1040 and Paul Eggert <eggert@cs.ucla.edu>
1042 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1043 from Automake with minor changes.
1044 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1046 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1048 * config/install-sh: Update to Automake CVS version, as follows:
1049 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1050 * lib/install-sh: Simplify the expr implementation of dirname.
1051 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1052 * lib/install-sh: Handle --, and diagnose unknown options.
1054 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1056 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1057 `./autom4te' to create `./testsuite', since the `all' target
1058 will ensure its presence, but `installcheck' should not create
1059 the uninstalled wrappers.
1061 * tests/torture.at (Unusual Automake input files): Skip if we
1062 detect automake < 1.8.
1064 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1066 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1067 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1068 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1069 * NEWS: Update.
1071 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1073 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1074 munge (multiple) white space and other oddities.
1075 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1076 single quotes in variable assignment.
1077 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1078 and similar failures by adding multiple spaces, tabs, and other
1079 special characters.
1080 Report and different test suggested by Francesco Romani
1081 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1083 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1084 single quotes, we only need to search for single quotes; this
1085 both simplifies the search pattern, and makes us less
1086 susceptible to `echo' variations for arguments not containing
1087 single quotes.
1088 (_AC_ARG_VAR_VALIDATE): Likewise.
1090 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1092 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1093 `$*' and IFS concatenation issue with traditional shells and
1094 bash-2.04. Report by Seanster@Seanster.com.
1096 2006-05-03 Bruno Haible <bruno@clisp.org>
1098 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1099 precisely which Mac OS X versions have the od problem.
1101 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1103 * doc/autoconf.texi: Use @option systematically.
1105 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1106 and Bruno Haible <bruno@clisp.org>
1108 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1109 about 'od'.
1110 (Integer Overflow): Mention the special case of integer division
1111 overflow.
1113 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1115 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1116 traditional shells like the Solaris one that do not use the
1117 first IFS character for assembling `$*'.
1118 Prompted by a related report from autoconf_bug@nro.ca.
1120 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1121 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1123 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1124 Mention more problems with the -e option.
1126 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1128 * NEWS: Typo.
1129 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1131 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1132 in URLs to improve DVI formatted output (requires texinfo 4.6).
1133 (System Services, Systemology, Shellology): Likewise.
1134 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1135 output.
1137 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1138 continuous text.
1139 (Runtime): Fix macro argument names to match description:
1140 `action-if-found' -> `action-if-true' and similarly.
1141 (Obsolete Macros): Likewise.
1142 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1143 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1144 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1146 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1148 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1150 * ChangeLog: Typo.
1151 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1152 DVI output.
1154 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1156 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
1157 /bin/sh set unsorted output.
1158 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
1159 * tests/local.at: Likewise.

1163 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1164 (Integer Overflow, Null Pointers, Buffer Overruns):
1165 (Floating Point Portability, Exiting Portably): New sections.
1166 (Writing Test Programs): Fix some langauge. Recommend exiting
1167 with status 1, not merely nonzero. Clarify exit declaration.
1168 (Run Time): Move C exit status stuff to new Exiting Portably section.
1169 (Systemology): Mention Posix and levenez. Update v7 reference.
1170 (Portable Shell): Mention the Posix shell.
1172 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1174 * bin/autoconf.as (me): Replace by as_me.
1176 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1178 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1179 since as_me isn't set yet.
1181 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1183 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1184 a few minor bugs in this area.
1186 * doc/autoconf.texi (Programming in M4sh): Comment out the
1187 documentation of AS_BASENAME, for now.
1188 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1189 (Limitations of Builtins) <basename>: Do not refer to
1190 AS_BASENAME.
1191 * bin/autoconf.as (me): Don't use AS_BASENAME.
1192 (dir): Remove the unused variable.
1193 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1194 AS_DETECT_REQUIRED. All uses changed.
1195 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
1196 All uses changed.
1197 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

1199 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1200 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1201 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1202 (_AS_DIRNAME_PREPARE): Likewise.
1203 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1204 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1205 (AS_DIRNAME): Use "dirname --".
1207 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1209 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1210 of "run time" and "run-time" changed to "runtime", for consistency.

1213 * lib/autoconf/general.m4: Likewise.
1214 * lib/autoconf/headers.m4: Likewise.
1216 * doc/autoconf.texi (Run Time): Document the exit status situation

1219 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1221 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1222 Archive is not officially `GNU' any more. Update URL.

1224 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1226 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1228 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1229 newline from the `trap' code to finish `config.log'; the NetBSD
1230 /bin/sh resets the exit status after an empty command, as
1231 documented in doc/autoconf.texi.
1232 Reported by Dalibor Topic <robilad@kaffe.org>.
1234 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1236 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1237 Suggested by Bruno Haible.
1239 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1241 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1242 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1243 Instead, just list the shells that we know work.
1244 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1245 changed. Be more cautious about the _cv_ variable.
1246 * tests/tools.at (Syntax of the shell scripts): Check the
1247 _cv_ variable once, at first, to avoid an internal autoconf error
1248 when sh -n does not work.
1250 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1252 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1254 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1256 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1257 use ">&-" since we're only 99.999% sure that this is portable,
1258 and since the MinGW bug is fixed in a different way.
1259 * lib/autotest/general.m4 (AT_INIT): Likewise.
1261 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1263 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1264 before opening config.log, to avoid hitting a bug on MinGW.
1266 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1268 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1269 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1270 This works around a MinGW bug reported by Eric Paire.
1271 Make sure that all writes to the log file append to it,
1272 rather than possibly losing data.
1273 * lib/autotest/general.m4 (AT_INIT): Likewise.
1275 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1277 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1278 description.
1280 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1282 * NEWS: Update.
1284 * configure.ac (AC_INIT): Bump to 2.59d.
1286 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1288 Version 2.59c.
1290 * Makefile.maint (news-date-check): Do not require a leading `*'
1291 before the release date in NEWS.
1293 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1294 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1296 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1297 the instantiated file do not contain the string 'datarootdir'
1298 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1299 @mandir@, replace the reference '${datarootdir}' by the value.
1300 * tests/torture.at (datarootdir workaround): New test.
1301 * NEWS: Advertise this temporary fixup.
1302 Based on a patch by Bruno Haible, reported and analyzed by
1303 Paul Eggert and Noah Misch.
1305 2006-04-12 Eric Blake <ebb9@byu.net>
1307 * tests/autotest.at (Debugging a failed test): Fix comment.
1309 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1311 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1312 all the changes since 2006-04-07.
1314 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1316 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1317 succeeded, but `ln -s file dir' failed, take care to remove the
1318 leftover target before the next test, to prevent its spurious
1319 failure; also make sure `ln file dir' works before selecting it.
1320 Thanks to Keith Marshall for pointing this out.
1321 * THANKS: Update.
1323 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1324 assignments in `at_debug_args', so that we put them correctly
1325 in the `run' script.
1326 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1327 Reported by Eric Blake.
1329 2006-04-11 Eric Blake <ebb9@byu.net>
1331 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1332 top-level tests after micro-suite has been run. Used in...
1333 (Debugging a successful test, Debugging script and environment),
1334 (Debugging a failed test): ...these new tests. The first of these
1335 is fixed by...
1336 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1337 macro, split out from...
1338 (AT_INIT): ...here, so that using -d also generates a run script.
1339 Document that -d inhibits top-level logging.
1340 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1341 inhibits top-level logging; debug scripts are created.
1343 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1344 check.
1345 * tests/autotest.at (Empty test, Empty check): New test to check it.
1347 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1348 from gcc.
1350 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1352 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1353 the files if a problem appears. Make the empty *.at files
1354 read-only, too. Proposed by Ralf Wildenhues.
1356 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1358 * config/Makefile.am: Add comment to force updated Makefile.in.
1360 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1361 space only patch to this file, this patch causes the Makefile.in
1362 files that include freeze.mk to be updated, and thus have a
1363 newer time stamp again, which in turn makes a pristine CVS
1364 checkout have correct time stamps.
1366 * Makefile.maint (cvs-sv): New macro, to be used..
1367 (config.guess-url_prefix, config.sub-url_prefix)
1368 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1369 point to CVS text checkout of Gnulib files.
1370 (copyright-check): Bump current year.
1371 (announcement): Do not hard-wire `./announce-gen'.
1372 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1373 correctly.
1374 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1375 `chmod +x'.
1376 (wget_files): Update config.guess, config.sub, texinfo.tex by
1377 `wget-update', now that their URLs work again.
1379 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1381 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1382 Problem noted by Paul D. Smith.
1384 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1386 * doc/autoconf.texi: Remove unused words from word list.
1387 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1388 .x-sc_trailing_space: New files.
1390 * doc/standards.texi: Sync from gnulib.
1392 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1393 `LIBOBJDIR' as experimental.
1395 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1396 with a target directory; it's internally implemented as `cp'
1397 anyway, but since Autoconf advertises the possibility to use
1398 a target directory when LN_S is `ln -s', we need to find out.
1399 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1400 analyzed by Keith Marshall <keith.marshall@total.com>.
1402 * THANKS: Update.
1404 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1406 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1407 confdefs.h as-is. In general, if it has backslash-newline or the
1408 like, then it doesn't work either to sort or to remove empty
1409 lines.
1411 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1413 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1415 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1417 * lib/autom4te.in (Automake-preselections): Preselect
1418 _AM_SUBST_NOTMAKE.
1420 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1422 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1423 apostrophe within a single-quoted string, as this is the usual
1424 tradition and is easier to read than '"'"'. Don't rely on the
1425 shell treating "$/" like '$/'. Use a more-consistent indenting
1426 style for the trap.
1428 2006-04-09 Eric Blake <ebb9@byu.net>
1430 * tests/autotest.at (Backquote command substitution),
1431 (Multiline backquote command substitution): Remove mistaken
1432 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1433 applied...
1434 (Parenthetical command substitution, Multiline parenthetical
1435 command substitution): here.
1437 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

1467 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1468 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1469 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1470 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1471 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1472 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1473 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1474 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1475 (Coding Style). Don't mention m4_expand_once.

1494 New macros.
1496 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
1497 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
1499 2006-04-08 Stepan Kasal <kasal@ucw.cz>
1501 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1502 of the warning introduced by the 2001-08-28 change.

1510 that contains braces.
1512 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1514 Revert the patch from 2006-04-01 and only improve
1515 _AS_DETECT_BETTER_SHELL:
1517 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1518 skip nonexistent directories.
1519 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1520 only shell candidates which exist.
1521 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1522 * lib/autotest/general.m4 (AT_INIT): No need to give three
1523 parameters to _AS_PATH_WALK.
1525 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1526 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1528 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1529 distinguish m4sugar macros.
1530 * tests/tools.at (autoupdating with aclocal and m4_include):
1531 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1532 test case by Noah Misch <noah@cs.caltech.edu>.
1534 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1536 Revert my change from 2006-03-17, in other words:
1537 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1538 and DUALCASE=1.
1539 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1540 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1541 it is set.
1543 2006-04-07 Eric Blake <ebb9@byu.net>
1545 * doc/autoconf.texi (Programming in M4sh): Document that
1546 AS_MKDIR_P exits the script on failure.
1547 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1549 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1551 * config/elisp-comp, config/install-sh, config/mdate-sh,
1552 config/missing, config/mkinstalldirs: Sync from Automake.

1561 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1562 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

1566 Eric Blake <ebb9@byu.net>,
1567 Paul Eggert <eggert@cs.ucla.edu>,
1568 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1570 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1571 whether `set' quotes correctly: redirect stderr of the tested
1572 `set', and use a subshell, for Ultrix; use `sed' instead of
1573 `grep' for zsh `set' which may write binary output; match only
1574 at the beginning of a line, to avoid false positives.
1575 In order to avoid false positives by unrelated variables with
1576 multiline content, put the dump algorithm in a subshell and
1577 unset all variables containing newlines (except some which are
1578 special to the shell). Warn about cache variables that are
1579 unset.
1581 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1583 * config/config.guess, config/config.sub, config/texinfo.tex:

1591 (AC_ARG_VAR): Do test this now.
1592 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1593 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1594 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1595 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1597 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1598 shell issue with double-quoted command substitutions of native
1599 commands.
1600 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
1601 Marshall.
1603 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

1618 2006-04-06 Stepan Kasal <kasal@ucw.cz>
1620 * tests/Makefile.am (maintainer-check-posix):
1621 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1623 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1624 ac_config_<foo>s again, sometimes normalized, sometimes not.
1625 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1626 (AC_CONFIG_COMMANDS): Do not do so here.
1627 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1628 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1629 2005-07-25 rewrite. Noticed by Noah Misch.
1631 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1632 _AC_PRESERVE_HELP_ORDER, ...
1633 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1635 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1636 inside m4_expand_once; it is redundant.
1638 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1639 for --help from Cygnus `configure.'
1641 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
1643 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
1644 on a patch proposed by Ralf Wildenhues.
1646 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1648 * lib/autoconf/status.m4: Replace <space>''<tab> with
1649 <tab><space> where this makes sense.
1651 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
1652 Noah Misch <noah@cs.caltech.edu>
1654 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1655 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1656 * doc/autoconf.texi (Help Formatting): New node.
1657 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1659 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1661 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1662 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1663 lib/autoconf/types.m4, lib/autotest/general.m4,
1664 tests/mktests.sh, tests/torture.at: White space cleanup:
1665 remove some SPACE before TAB, or add quoting ('' or @&t@).
1667 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1669 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1671 2006-04-05 Eric Blake <ebb9@byu.net>
1673 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1674 empty test suite works.
1675 * tests/autotest.at (Empty test suite): Remove xfail.
1677 2006-04-05 Noah Misch <noah@cs.caltech.edu>

1680 TAGS to ac_config_<foo>s.
1681 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1682 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1683 normalizing it, consistent it with previous releases.
1684 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1686 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1688 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1689 Use simplified args that Eric Blake originally suggested.
1691 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1693 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1694 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1695 Use 'comm' rather than N instances of grep; this also fixes a bug
1696 whereby substrings were incorrectly matched, causing us to not
1697 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1698 (exclude_list): Exclude empty macros.
1699 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

1704 Switch from grep to awk syntax.
1705 (ac_exclude_script): Renamed from ac_exclude_egrep.
1706 (au_exclude_script): Renamed from au_exclude_egrep.
1708 2006-04-04 Noah Misch <noah@cs.caltech.edu>
1710 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
1711 a subdirectory subject to Cygnus `configure'.
1712 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
1714 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
1715 report request when we have no AC_PACKAGE_BUGREPORT.
1717 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1719 * THANKS: Update.

1722 generated files.
1724 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
1725 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a

1736 (output): Emit AC_CONFIG_SUBDIRS as needed.
1737 * tests/autoscan.at (autoscan): Remove XFAIL.
1739 2006-04-03 Noah Misch <noah@cs.caltech.edu>
1741 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
1743 2006-04-03 Eric Blake <ebb9@byu.net>
1745 * THANKS: Add myself.
1747 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1749 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
1750 to log, point to testsuite output tree.
1752 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
1754 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
1755 * doc/autoconf.texi (Function Portability): Mention that C++
1756 has trouble with 'exit'.

1759 Remove; all uses removed.
1760 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

1780 Clean up _AC_COMPILER_EXEEXT* macros.
1782 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1783 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1784 ac_file to the name of the default output file and call
1785 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1786 initial `rm' of the candidate files...
1787 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1788 the same list in subsequent `rm' calls, and for the temporary
1789 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1790 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1791 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1792 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1793 no longer needed) by libtool. Make it a cache check.
1794 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1795 copied here by mistake.
1796 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1797 _AC_COMPILER_EXEEXT.
1798 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1799 _AC_COMPILER_OBJEXT directly.

2572 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2573 by the function rather than ignoring it.
2574 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2575 comparing its address. Intel's interprocedural optimization was
2576 outsmarting the old heuristic. Problem reported by

2594 Stepan Kasal <kasal@ucw.cz>
2596 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2597 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2598 make its content writable before removing it. Remove an errorneous
2599 comment from the end, where the logs of the failed tests are copied
2600 to the main log file.
2602 2005-09-27 Stepan Kasal <kasal@ucw.cz>

2609 problems if the testsuite were running too fast.
2611 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2613 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

2625 suggested by Ben Elliston. Handle weird characters correctly.
2627 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2629 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2630 calls, so that the final expansion of this macro is shorter.
2631 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2632 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2633 the cleanup there. Use AS_VAR_* macros, to be more general.
2634 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2636 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2638 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

2656 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2658 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2659 in the example. Reported by Bruno Haible.
2660 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2661 "if $undefined_var;" succeeds with my shell.
2663 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2664 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2665 but change the m4_divert_text to m4_divert_once.

2675 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2676 some evil values and relying on the fact that $* concatenates the
2677 parameters by the first character from IFS.
2679 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2680 Stepan Kasal <kasal@ucw.cz>
2682 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2683 first header appears, define AH_HEADER.
2684 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2685 Update limitations about when to call AC_CONFIG_HEADERS.
2686 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2687 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2688 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2689 ``Configuration Actions''; fix their index entries.
2691 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2692 options correctly. Process N-M as M-N if M is smaller than N.
2693 Process ranges correctly so that N-N will run only N.
2694 Sort and uniquify the tests that will be run. If there is more
2695 than one test, reinsert the banners for the tests.

2701 before passing the macro name to AH_TEMPLATE.
2703 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2704 now opens log after option processing; in particular, --version
2705 and --help do not touch config.log.

2722 Prepend to LIBS, not append, in examples.
2724 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2726 When building in place, set srcdir="."; suggested by Tim Van Holder.
2728 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2729 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2730 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2731 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

2745 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2746 add "2>&1"; gzip 1.2.4 prints help on stderr.
2748 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2750 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2751 was pushdef'ed twice while popped only once. Push it only once.
2752 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2754 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2756 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
2757 prefixed by mere "===", not "configure: === ".
2759 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
2761 * Makefile.maint: Update from Bison.
2763 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2764 "<tab>" in comment, so that the point is understandable.
2766 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2768 Rewrite substantial part of lib/autoconf/status.m4.
2769 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2770 and CONFIG_COMMANDS are not processed in four separate loops.
2771 Instead, there is one main loop. This alows that the common code
2772 is expanded only once, thus config.status (and configure) is smaller.
2774 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2775 the AC_LIST_FILES and cousins macros are no longer used.
2777 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2778 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2779 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2780 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2781 contain the initialization, nor the for loop, nor the associated
2782 commands; all these go to ...
2783 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2784 _AC_OUTPUT_CONFIG_STATUS.
2785 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2786 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2787 (_AC_OUTPUT_FILE): The creation of the sed script ...
2788 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2789 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2790 _AC_OUTPUT_MAIN_LOOP.
2791 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2792 _AC_CONFIG_COMMANDS): Use ...
2793 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2794 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2795 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2796 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2797 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2798 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2799 ... new macros.
2800 (_AC_CONFIG_UNIQUE): Update.
2801 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2802 Replaced by this ...
2803 (_AC_LIST_TAGS): ... new common macro.
2804 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2805 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2806 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2807 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2808 this didn't belong to the `config commands' section.
2809 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2810 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2811 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2812 to the `config commands' section either.
2813 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2814 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2816 ... and many changes to the comments nearby.
2818 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2819 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2820 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2821 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2822 (#define header templates): The comment at the top of the generated
2823 header now includes the name(s) of the source file(s).
2825 Several unrelated small changes:
2827 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2828 parameter to AC_DIAGNOSE.
2829 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2830 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2831 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2832 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2833 with AU::AC_OUTPUT.
2834 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2835 in AC_OUTPUT doesn't double-quote it either.
2836 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2837 parameters.
2839 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2841 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2842 versions of Portland Group compiler produce single- and double-quoted
2843 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2844 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2846 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2848 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2849 This is a corrected version of yesterday's patch.
2851 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2853 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2854 path, too; insert a "===" to emphasize the line.
2856 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2857 ac_cv_build_alias to ac_build_alias.
2858 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2860 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2861 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2862 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2863 (AC_ARG_VAR): ... here.
2864 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2865 target_alias.
2867 Keep a list of all precious variables and process them with one simple
2868 for loop, instead of expanding all commands, or, OTOH, complicated
2869 processing of output of "set".
2870 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2871 variable names in new macro...
2872 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2873 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2874 a loop to assign all ac_env_* and ac_cv_env_* variables.
2875 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2876 to INIT_PREPARE.
2877 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2878 its value to shell variable ac_precious_vars and call
2879 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2880 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2881 _AC_ARG_VAR_VALIDATE.
2883 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2884 and the AC_SUBSTs ...
2885 (AC_INIT): ... here.
2887 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2888 the ac_subst_files section in config.log.
2890 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

2899 Fix problems reported by Nicolas Joly.
2900 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
2901 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2902 They are generated by the Tru64 v5.1B shell.
2904 2005-07-05 Stepan Kasal <kasal@ucw.cz>
2906 Fix my changes from 2005-07-01; reported by Noah Misch.
2907 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2908 description, the macro now accepts only a single tag.
2909 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
2911 Fix cases when the varsions of Autoconf and Autotest don't match.
2912 Reported by Noah Misch.
2913 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
2914 at_top_builddir, for compatibility with older autotest.
2915 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2916 is not set, use at_top_builddir, for compatibility with older
2917 versions of autoconf.
2919 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2921 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2922 Problem reported by Patrick Welche.
2924 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2926 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2927 sed substitution command, so that we allow | in program prefixes
2928 and program suffixes. (& is a problem anyway; we're not fixing
2929 that here.)
2930 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2931 configure_input, top_builddir, srcdir, etc.
2932 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2933 PATH_SEPARATOR in AUTOTEST_PATH.
2935 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2937 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
2938 for loop over config.site files using `set', to allow
2939 directory names containing IFS characters.

2943 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2944 directories with weird names. Apparently some people like living
2945 on the edge. However, improve the test that "pwd" actually does
2946 report a name for the working directory.

2962 (Generic Functions): Mention the Gnulib project.
2963 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
2965 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2966 document to output the default config_* lists to config.status.
2967 Don't recognize option --file, if the functionality is not there.
2968 Likewise for --header; moreover, recognize --he and --h as shortcuts
2969 for --help in that case.
2971 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2972 matches the order of execution. No code changed.

2993 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
2994 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2995 (AC_SUBST): Call it.
2996 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2997 the directory specific variables; but don't call it for configure_input.
2999 2005-06-28 Derek Price <derek@ximbiot.com>
3001 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3002 addition.
3004 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3006 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3007 directory have inherent problems with special characters like spaces,
3008 due to limitations in Make syntax. Problem reported by Alexandre
3009 Duret-Lutz.
3010 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

3023 from Justace Clutter.
3024 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
3025 variable into diagnostic. Make the diagnostic an error, not a warning,
3026 because we really don't support spaces and suchlike in dir names.
3027 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3028 Don't worry about backslashes in srcdir; it can't happen now.
3029 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
3030 Simplify ac_optarg handling.
3031 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

3039 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3041 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3042 that '\|' is not allowed in BREs; recommend using newline separated
3043 list of patterns instead of multiple -e options.
3045 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
3047 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

3053 2005-06-21 Stepan Kasal <kasal@ucw.cz>
3055 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3056 b, t, r, w commands require single space, while : cannot have any.
3057 (Special Shell Variables): Fix sed code this in the example.
3058 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3059 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3061 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3062 expand to the empty list. Don't use two pairs of m4_changequote,
3063 it's not necessary.
3065 2005-06-20 Derek Price <derek@ximbiot.com>
3067 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
3069 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
3071 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3072 * doc/autoconf.texi:
3073 Don't mention Solaris versions so much, if a
3074 problem is common to all extant versions of Solaris. Say "SunOS
3075 4" instead of "SunOS" for SunOS 4.
3076 (awk): Mention more of the limitations of traditional Awk.
3077 (cat): Don't talk about cat -v.
3079 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
3081 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
3082 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

3084 to be compatible with glibc strverscmp.
3085 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
3087 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3088 on Mac OS X 10.4 reported by Peter O'Gorman in:
3089 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
3090 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
3091 Use shell builtins rather than 'expr', to work around expr bug.
3093 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3095 * doc/autoconf.texi: "filesystem" -> "file system".
3096 "behaviour" -> "behavior".
3097 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
3098 * lib/autoconf/general.m4: Omit blank after ":" sed command,
3099 as per POSIX.
3100 * lib/m4sugar/m4sh.m4: Likewise.

3102 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
3104 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
3105 (.x.1): Ignore the time stamp in the .TH line when deciding whether
3106 to update the man page. That way, we don't have to check in new
3107 man pages every month.
3109 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
3110 quotes and backslashes. Patch from Derek Price.
3112 2005-06-10 Derek Price <derek@ximbiot.com>
3114 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
3115 AS_TR_SH.
3117 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
3119 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3120 -u, since it outputs chatter if the input files are the same.
3121 Problem reported by Ralf Menzel.
3123 2005-06-08 Derek Price <derek@ximbiot.com>
3125 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3126 renaming them since they are about to be redefined anyhow.
3128 2005-06-08 Derek Price <derek@ximbiot.com>
3130 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3131 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3132 Move m4_undefine to alphabetical order.
3134 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3136 * README: Recommend GNU M4 1.4.3 or later.
3137 * doc/autoconf.texi (Introduction): Likewise.
3138 Reword to avoid some formatting glitches.
3139 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3140 Clarify explanation of HP compiler bug.
3141 Redo example output tp match current CVS snapshot.
3142 Use @example.org in email addresses when the examples
3143 might get inadvertently cut-and-pasted into user code.
3144 Remove example of autom4te usage that doesn't seem to work now.
3145 Use modern AC_INIT (except when the example is meant to be
3146 shown with Autoconf 2.13).
3147 Update ksh info for Solaris 9 and later.
3148 KB -> kB.
3149 Modernize description of Automake versions a bit.
3150 Don't claim a future version of Autoconf is near.
3151 * doc/install.texi: Reword to avoid some formatting glitches.
3153 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3155 * doc/autoconf.texi: Add [] to examples, so that the manual
3156 follows its own advice about quoting better.
3157 Reword to avoid some formatting glitches.
3158 * doc/installt.exi: Reword to avoid some formatting glitches.
3160 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3161 Tru64 ksh pattern matching bug. Reported against Libtool by
3162 Albert Chin <libtool@mlists.thewrittenword.com> and
3163 Nicolas Joly <njoly@pasteur.fr>.
3165 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3167 m4_cdr of one-member list was [[]] (one-member list containing an
3168 empty string) instead of [] (an empty list. Callers were skewed to
3169 match this misbehaviour. As a consequence of this:
3170 - m4_foreach([x], [], [foo]) expanded to `foo', while
3171 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3172 This bug has been fixed:
3174 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3175 expand to an empty string; print error msg if called without
3176 an argument list.
3177 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3178 misbehaviour; handle [] and [[]] correctly.
3180 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3182 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
3183 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
3184 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
3186 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3188 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3189 swallow records with more than 99 fields.
3190 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3191 parse the long line.
3193 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3195 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3196 swallow literals longer than 399. Reported by Ralf Wildenhues.
3197 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
3198 to workaround this limitation.
3200 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3202 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3203 to gfortran, and make these the first two compiler names
3204 checked (following the general autoconf preference for gcc).
3206 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3208 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3209 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3210 (testsuite): Make sure autotest.m4f is up-to-date before using it.
3212 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
3214 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3215 expression of unbounded size when processing the --list
3216 option. This runs afoul of a limit of 399 bytes per regular
3217 expression on AIX. Problem reported by Ralf Wildenhues.
3219 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
3221 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
3222 * doc/autoconf.texi (Particular Headers): Reword example
3223 for multiline stdbool replacement.
3224 (Setting Output Variables): Reword text a bit. Don't
3225 give all the details about |#_!!_#|.
3226 Reword description of line replacement.
3228 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3230 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3231 now contain newlines, and substituted files must be referenced on
3232 a line alone; the sed scripts to substitute them are now very
3233 different.
3234 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3235 commands can be put in a sed script portably.
3236 * doc/autoconf.texi (Setting Output Variables): Document above
3237 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3238 use of multiline substitution.
3239 * tests/torture.at: No longer expect substitution of newline to fail.
3241 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
3243 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
3244 From Ralf Menzel (trivial change).
3246 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
3248 * tests/local.at: Don't attempt to check for negated character
3249 classes in shell scripts. The test was too brittle.
3251 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3253 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3254 * doc/autoconf.texi (Limitations of Builtins): Document this
3255 limitation.
3257 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3259 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3260 common code; used in many places in the tree.
3261 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
3262 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
3264 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
3266 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
3267 messages when ac_unique_file is not found.
3268 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3269 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3270 commands, for consistency with AC_MSG_ERROR and such.
3272 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3274 * bin/Makefile.am: Merge the two rules for creating scripts.
3276 2005-05-23 Stepan Kasal <kasal@ucw.cz>
3278 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
3279 obsolete; it was never documented.
3280 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
3282 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3284 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3285 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3286 (ac_top_builddir): ... this ...
3287 (ac_top_build_prefix): ... to this; the old name is also kept, for
3288 backward compatibility.
3289 (ac_top_builddir_sub): New variable, without the trailing slash,
3290 always nonempty.
3291 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3292 * doc/autoconf.texi (Configuration Actions): Rename
3293 ac_top_builddir to ac_top_build_prefix.
3294 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
3295 at_top_builddir to at_top_build_prefix.
3296 * lib/autotest/general.m4 (AT_INIT): Likewise.
3298 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3300 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
3301 of confdefs.h .
3303 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3305 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3306 argument to m4_foreach. I guess it was necessary in the past,
3307 but I think it's a no-op now.
3309 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3311 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3312 ``cat <<_ACEOF'' commands to one.
3313 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3314 * lib/autoconf/status.m4: On various places, use expr instead of
3315 ``echo|sed.''
3316 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3317 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3318 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3319 a range.
3320 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3321 the wrong patterns between ``case'' and ``esac.'' The previous
3322 code had false positives.
3324 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3326 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3327 as on 2005-05-02.
3328 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3329 Mention LIBOBJDIR.

3369 2005-05-13 Stepan Kasal <kasal@ucw.cz>
3371 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
3372 check.
3373 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3374 enough arguments, similarly as in m4_bpatsubsts.
3376 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3378 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
3379 of absolute paths.
3381 2005-05-11 Stepan Kasal <kasal@ucw.cz>
3383 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3384 for absolute directory names in one loop.
3385 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3386 abbreviations of --version and --debug.
3388 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3390 * doc/autoconf.texi (Autoconf Language): Be more precise about
3391 quoting rules. Problems noted by Stepan Kasal.
3392 Also, throughout this document, be more careful about white space.
3393 "blank", "white space", and "space" all have different meanings
3394 and we should be careful to say what we mean.
3396 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3398 Fix C++ related problems reported by Werner Lemberg.
3399 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3400 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3401 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3402 avoid problems with C++ and throw.
3403 * tests/compile.at: .cpp, not .cc.
3405 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3407 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3409 * doc/autoconf.texi (Generic Functions): Typos.
3411 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3413 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3414 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3415 set by latest automake.
3417 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3419 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3420 outputs 0 on GNU/Linux these days.
3422 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3424 * doc/autoconf.texi (Autoconf Language): Add more description
3425 about quoting heuristics.
3426 (Limitations of Builtins): Describe "set -" problems.
3428 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3430 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3431 not newline.
3433 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3434 by AC_DEFINE; it was a mistake.
3435 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3437 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3439 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3441 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3443 * doc/autoconf.texi (External Software): Quadrigraphs are not
3444 processed correctly in AS_HELP_STRING; avoid this in the examples.
3445 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3446 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3447 comment and reduce m4_default([foo], []) to [foo].
3448 (m4_strip): Update the explanation.
3450 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3452 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3453 Remove core.conftest.* too; it's generated by Tru64 5.1.
3454 Problem reported by Jennis Pruett.
3455 * lib/autoconf/functions.m4
3456 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3457 Don't bother to remove core files; AC_RUN_IFELSE should do that
3458 for you.
3460 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3462 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
3464 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
3466 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
3467 Report from Horst Wente.
3469 2005-04-15 Stepan Kasal <kasal@ucw.cz>
3471 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
3472 the comment.
3474 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3476 * doc/autoconf.texi (External Software, Package Options): Add
3477 examples showing how to implement --with-* and --enable-* options.
3479 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3481 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3482 as well as configure.in. Problem reported by Gregorio Guidi.
3484 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3486 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3487 pattern for alloca snippet.
3489 2005-04-04 Stepan Kasal <kasal@ucw.cz>
3491 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
3493 2005-04-01 Stepan Kasal <kasal@ucw.cz>
3495 * doc/autoconf.texi (Generic Programs): Fix a typo.
3497 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3499 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3500 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3502 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3504 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3505 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3506 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3507 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3508 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3510 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3512 * NEWS: The configure command now warns you if you attempt to use
3513 a directory whose name contains a special character like space,
3514 newline, or "\".
3515 * doc/autoconf.texi (Installation Directory Variables): Allow
3516 "," in file names. Do not use \@; it's not a portable regexp.
3517 * bin/Makefile.am (edit): Likewise.
3518 * lib/Makefile.am (edit): Likewise.
3519 * tests/Makefile.am (edit): Likewise.
3520 * tests/semantics.at: Likewise.
3521 * tests/torture.at: Likewise.
3522 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3523 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3524 * doc/autoconf.texi (File System Conventions): Warn about
3525 unportable file names.
3526 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3527 (AC_INIT): Use it.
3528 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3529 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3530 ac_pwd, and quote srcdir.
3531 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3533 * doc/autoconf.texi: Fix some systematic formatting problems.
3534 ".)" needs a following @: if not at the end of a sentence, and
3535 similarly for "!)". "etc." should be preceded by a comma.
3536 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3538 2005-03-22 Bruno Haible <bruno@clisp.org>
3540 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3541 argument is often called 'build-aux'.
3543 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3545 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3546 macro AC_TRY_LINK is obsolete.
3547 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3548 `AC_CONFIG_FILES'.
3550 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3552 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3553 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3554 from a Common Lisp's `cl'.
3555 (AC_PROG_CXX): Behave according to the documentation: don't
3556 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3557 make the variable CCC precious; use `cl.exe', not `cl'.
3559 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3560 Alexandre Duret-Lutz <adl@gnu.org>
3562 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3563 /dev/null, as "configure" shouldn't read stdin, and this insulates
3564 us from problems (e.g., when testing for "cl"). Also, do this
3565 redirection before invoking "hostname" or "uname", and keep the
3566 original input stream available via...
3567 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3568 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3569 bother with "</dev/null" since it's now done at the top of
3570 'configure'.
3571 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3572 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3573 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3574 * doc/autoconf.texi (File Descriptor Macros): New section.
3575 (Printing Messages): Mention it.
3576 * tests/base.at (Input/Output): New test.
3578 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3580 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3581 newline if neither \c nor -n work, as that would output two
3582 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3584 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3586 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3587 This causes that any required macros inside will get before the if.
3588 * doc/autoconf.texi (autom4te.cache): A typo.
3590 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3592 Undo previous change, except keep the change to
3593 lib/autoconf/programs.m4 that replaced grep with shell
3594 pattern-matching. This is because net-snmp configure reads stdin.
3595 Reported by Noah Misch.
3597 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3599 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3600 from /dev/null, as "configure" shouldn't read stdin, and this
3601 insulates us from problems (e.g., when testing for "cl").
3602 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3603 before invoking "hostname" or "uname".
3604 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3605 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3606 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3607 "</dev/null" since it's now done at the top of 'configure'.
3608 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3609 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3610 Also, replace grep with shell pattern-matching, to save a process.
3612 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3614 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3615 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3616 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3617 compiler.
3619 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3621 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3622 grep -q isn't portable. Improve grep -s explanation.
3623 Problem reported by Dan Manthey.
3625 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>

3715 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3717 Try not to generated lines of unlimited length, as POSIX places a
3718 2047-byte limit on line length of portable text files.
3719 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3720 Use newline as a separator, not space.

3723 space.

3778 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3779 Update the long comment explaining it.
3781 m4_require no longer writes an ``is required by'' line to the
3782 execution stack. It contains only one bit of non-redundant
3783 information: that the macro was required, not called. And even
3784 this bit is useless in most situations: have you ever met a macro
3785 which both calls and requires the same macro?
3787 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3788 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3795 (_m4_require_call): Use it.
3796 * tests/m4sugar.at (m4_require): Expect output without the
3797 ``is required by'' messages.
3799 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3801 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3802 rather than x for expr.
3804 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3805 this is safe.
3806 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
3807 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

3820 support.
3821 * bin/autoheader.in: Pass $force to update_file so that
3822 config.h.in is always recreated when --force.

3828 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3830 * doc/autoconf.texi (Limitations of Builtins): Clarify that

3833 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3835 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3836 Warn about newline stripping in `` and $(). Update Solaris
3837 version to 9.
3838 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3839 X insulates us from future changes to Posix.
3840 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3841 stripping.
3843 2005-01-19 Stepan Kasal <kasal@ucw.cz>

3861 ulongval to be static, to avoid unwanted GCC warning. Problem
3862 reported by Michael Jennings via Daniel Reed; see
3863 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
3865 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3867 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3889 (_m4_divert_n_stack): New macro; the expansion is
3890 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
3891 otherwise.
3892 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3893 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3894 stored in _m4_divert_diversion or _m4_divert_dump.
3895 (m4_divert_pop): When the parameter is given, compare the symbolic
3896 name with the last diversion pushed on the stack. Previously, the
3897 current diversion was compared with the numeric value of the
3898 diversion given as the parameter.
3899 (m4_require): If the macro hasn't been expanded yet, call ...
3900 (_m4_require_call): this new macro.

3933 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

4114 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):
4115 Don't depend on .x file explicitly, since "make" does that for us.
4116 Suggested by Stepan Kasal.

4179 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
4181 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
4182 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
4183 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
4184 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
4186 2004-12-07 Stepan Kasal <kasal@ucw.cz>
4188 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

4203 with exactly one parameter.
4205 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4207 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4208 "char c = '\200';" rather than "char c = 0x80;" as the
4209 latter doesn't conform to the strict C standard due to
4210 overflow on signed char hosts.
4212 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4213 to -qlanglvl=ansi. We don't want to disable extensions.

4274 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
4275 the $1_found variable, don't test whether the file is executable;
4276 Both things are checked ...
4277 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
4278 the former ``test -f''.

4281 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

4291 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
4293 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed

4314 Problem reported by Stepan Kasal.
4316 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
4318 Fix problems reported by Andreas Buening in:
4319 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html

4321 in test makefile.
4322 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

4325 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4327 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4328 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4329 (trivial change). Problem and patch reported by Andrew Church in:
4330 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4332 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

4359 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4360 texinfo.tex for now (done by hand now).
4361 * Makefile.maint (wget_files, cvs_files):
4362 Remove ansi2knr.c; nobody uses it.
4363 (ansi2knr.c-url_prefix): Remove.
4364 (cvs-update): Fix test for failure. I don't know why it ever
4365 worked...
4367 * doc/autoconf.texi: Update URLs, some of which went stale.
4368 Use @uref rather than @href.
4370 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4371 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4373 * config/config.guess, config/config.sub, config/elisp-comp,
4374 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4375 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4377 * NEWS, TODO, configure.ac, bin/autoscan.in,
4378 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4379 doc/install.texi, lib/Autom4te/Configure_ac.pm,

4383 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4384 tests/tools.at, tests/torture.at:
4385 Use "file name" rather than "filename" or "path",
4386 to be consistent with the terminology of the GNU coding standards.
4388 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4390 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4391 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4392 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4393 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4395 More fixes to support spaces in the name of the build directory.
4396 This isn't a complete fix but it's an improvement.
4398 * bin/autoconf.as (autom4te_options): New var.
4399 Use it instead of appending to AUTOM4TE, so that we can allow
4400 spaces in the build directory's absolute name.
4401 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4402 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

4413 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4415 * doc/autoconf.texi (Function Portability): Document isinf and
4416 and isnan. From a suggestion by Kevin Ryde.
4418 * lib/Autom4te/General.pm (END): Return correct exit status even
4419 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4421 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4423 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4424 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4425 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4427 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4429 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4430 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4431 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4432 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4433 * lib/autom4te.in (Automake-preselections): Preselect
4434 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4436 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4438 * lib/autom4te.in (Automake-preselections): Preselect
4439 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4440 trace them.
4442 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4444 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4445 Tru64.
4446 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4447 Document problem with "`""`" in pdksh POSIX mode.
4449 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4451 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4452 with pdksh, too. Problem reported by Patrick Welche via
4453 Gary V. Vaughan.
4454 * doc/autoconf.texi (Shellology): Note that set -o posix is
4455 useful for pkdsh, too.
4457 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4459 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4460 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4461 Don't fail if ENV or BASH_ENV is readonly.
4462 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4463 etc. are read only. Problem reported by Ludovic Courtes.
4465 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4467 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4468 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4469 (trivial change)
4471 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4473 * doc/autoconf.texi (File System Conventions): Warn about
4474 names like "aux". Problem reported by Eric Blake.
4476 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4477 by zero instead of array size, so that we can use any arithmetic
4478 constant expression (instead of requiring an integer constant
4479 expression). This allows us to test expressions like DBL_MAX <
4480 LDBL_MAX, which didn't conform to the C standard using the old
4481 method.
4482 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4483 now that we can do floating-point tests at compile time.
4485 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4487 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4488 and LDBL_EPSILON, as the resulting expression isn't an
4489 integer constant expression and violates the C standard.
4490 Problem reported by Nelson H. F. Beebe. Also, check
4491 for "L" suffix, and check that long double doesn't have
4492 worse range or precision than double, that mixed-mode
4493 arithmetic doesn't generate a diagnostic, that double
4494 constants fit in long double.
4496 2004-06-03 Kevin Ryde <user42@zip.com.au>
4498 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4499 malloc(0) and realloc(NULL,size).
4501 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4502 Bob Proulx.
4504 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4506 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4507 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4508 by Jim Meyering.
4510 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4512 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4513 can be rewritten using if-then-else. Suggested by Bruno Haible.
4515 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4517 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4518 Problem reported by Stepan Kasal.
4520 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4522 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4523 change). Patch reported by Ralf Wildenhues in
4524 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4526 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4527 function F exists if the compiler and linker let you compile an
4528 expression like (F != 0). Recent versions of GCC optimize away
4529 the reference to F in that case, since every function address must
4530 be nonzero, so the link succeeds even if F does not exist.
4531 Problem reported by Manu in
4532 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4534 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4535 "Unix". Many uses changed.
4536 (Limitations of Builtins): Explain better why the ! command isn't
4537 portable.
4539 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4541 * lib/autom4te.in (Automake-preselections): Preselect
4542 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4544 2004-05-19 Kevin Ryde <user42@zip.com.au>
4546 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4547 referencing AC_FUNC_STRERROR_R.
4549 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4550 note pessimistic assumption when cross compiling.
4552 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4554 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4555 (until 2004) invoked subcommands with sh -e, contra POSIX.
4556 Reported by Kevin Ryde.
4558 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4560 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4561 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4562 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4563 `test -f " /usr/bin/grep"', which _always_ failed.
4564 (AC_PROG_SED): Ditto bogus PATH fix.
4565 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4566 requires that grep correctly supports _multiple_ `-e' options, rather
4567 than stating only that grep should accept `-e'.
4569 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4571 Port to C99, which requires that 'exit' be declared.
4573 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4574 to ensure that stdlib.h is included.
4575 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4576 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4577 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4578 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4579 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4580 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4581 when using 'exit' in a test; C99 requires that 'exit' be declared.
4583 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4585 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4586 now prefers 'grep' implementations that accept -e.
4587 (Limitations of Usual Tools): Describe problems of traditional
4588 egrep and fgrep with long input lines, and of traditional grep
4589 with -e.
4590 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4591 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4592 All callers changed. Append /usr/xpg4/bin to the PATH, for
4593 Solaris.
4594 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4595 the user with complaints about multiple -e options.
4596 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4597 Define it with AC_PROG_GREP.
4598 * configure.ac (AC_PROG_GREP): Add.
4599 * lib/freeze.mk (GREP): New macro.
4601 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4603 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4604 a possible candidate only after all others fail, rather than
4605 consulting it first. This improves backward compatibility by
4606 better reflecting the way shell selection occurred in previous
4607 versions of Autoconf, and should help to avoid triggering latent
4608 problems in other packages, such as the one in Automake where zsh
4609 is not handled robustly:
4610 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4611 Although it is not Autoconf's responsibility to work around
4612 problems in Automake, it nevertheless makes sense to avoid
4613 introducing unnecessary incompatibilites.
4615 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4616 Gary V. Vaughan <gary@gnu.org>
4618 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4619 how deeply nested we are when a suitable tool is found, set the
4620 ac_path_TOOL_found flag.
4621 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4622 nested we are in this macro. Break out of all 3 nested loops if
4623 ac_path_TOOL_found is set.
4625 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4627 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4628 of the _AS_PATH_WALK loop too if GNU flavor is found.
4630 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4632 * doc/autoconf.texi (Limitations of Make): Update documentation
4633 for `$<'. New entry `Long lines', based on a report from Simon
4634 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4635 paragraph about DJGPP, based on a mail from Richard Dawe.
4637 2004-04-20 Paul Eggert <eggert@twinsun.com>
4639 * tests/c.at (C keywords): Don't assume that GCC supports
4640 "restrict" and "inline", as sufficiently-old GCC versions do not
4641 (also, GCC configured to be in pedantic C89 mode does not).
4642 Problem reported by Sumit Pandya in:
4643 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4645 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4646 consider -g to work if it generates warnings when plain compiles
4647 don't. Problem reported by Braden McDaniel in:
4648 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4650 * doc/autoconf.texi (Slashes): New section, to document a problem
4651 reported by Jim Meyering in:
4652 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4654 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4655 linker output files before linking, to work around IRIX 6 linker bug.
4656 Problem reported by Rainer Orth in:
4657 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4659 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4661 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4662 best tool so far counter rely on the tool path variable name to
4663 avoid checks for one tool being affected by the results of running
4664 the length check on a previous tool.
4666 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4667 match expression argument, as different greps have different
4668 regular expression flavours.
4669 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4670 literals.
4671 (AC_PROG_EGREP): Pass 'EGREP$'.
4672 (AC_PROG_GREP): Pass 'GREP$'.
4674 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4676 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4677 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4679 2004-03-29 Paul Eggert <eggert@twinsun.com>
4681 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4682 Types, Specific Compiler Characteristics, System Services,
4683 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4684 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4685 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4686 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4687 Likewise.
4688 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4689 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4690 AC_TYPE_OFF_T): Likewise.
4691 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4692 Likewise.
4694 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
4695 pacify libtool 1.5.2. Fix quoting problems in sed command.
4697 2004-03-28 Paul Eggert <eggert@twinsun.com>
4699 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4700 now defines HAVE_DECL_TZNAME if it is declared, when
4701 HAVE_STRUCT_TM_TM_ZONE is not defined.
4702 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4703 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4704 for HAVE_TZNAME.
4706 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4708 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4709 superfluous backslashing of quotes (") in sed expressions;
4710 thanks to Paul Eggert.
4712 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4714 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4715 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4716 H. F. Beebe for the bug report.
4718 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4720 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4721 quoted -cmdline argument in Portland Group compiler (bug
4722 reported by Jeffrey J. Barteet).
4724 2004-03-25 Kevin Ryde <user42@zip.com.au>
4726 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4727 (Run Time): ... here, where it's now mentioned.

4731 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4732 inherits from language Autoconf-without-aclocal-m4.
4733 (Customizing autom4te): Adjust example; the cache must now be
4734 disabled for language Autoconf-without-aclocal-m4.
4736 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
4737 Nathanael Nerode <neroden@twcny.rr.com>

4748 AC_CHECK_TOOLS.
4749 (Specifying Names): Document the reason for these future
4750 behavioral changes.
4751 * tests/mktests.sh: Do not generate tests for the
4752 new macros.
4753 * NEWS: Document these changes.
4755 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4756 they make TeX hang up.

4760 * NEWS: New macro AC_CHECK_ALIGNOF.
4761 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4762 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4763 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4764 vowel.
4765 (AC_CHECK_ALIGNOF): New macro.
4766 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
4767 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
4768 those for sizeof.
4770 2004-03-03 Paul Eggert <eggert@twinsun.com>
4772 * bin/Makefile.am (edit): Don't use $< in a context where
4773 POSIX doesn't require support for it. Use $@.in instead.
4774 Problem reported by Anthony N. Frasso in
4775 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4776 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4778 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4780 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4781 from the next generation of Libtool.
4782 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4784 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4786 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4787 is not always thread-safe. Report from Nathanael Nerode.
4789 2004-02-18 Paul Eggert <eggert@twinsun.com>
4791 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4792 problem on QNX reported by Stephen Rasku in
4793 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4795 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4796 $(m4sh_m4f_dependencies); this removes a FIXME.
4797 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4798 (MAINTAINERCLEANFILES): Split into pieces,
4799 one per related section. Add $(srcdir)/wrapper.in.
4801 2004-02-09 Paul Eggert <eggert@twinsun.com>
4803 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4804 AC_SUBST provides no portable way to escape literal newlines.
4806 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4807 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4808 Darwin uses -lcrt2.o and there's little point to cataloging all
4809 the system variants. Partial fix reported by Andreas Waechter in:
4810 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4811 for bug reported by Nelson H. F. Beebe in:

4814 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
4816 * doc/autoconf.texi (AU_DEFUN): Fix English,
4817 suggested by Paul Eggert.
4818 * lib/autoconf/autoupdate.m4: Correct reference to
4819 acobsolete.m4, suggested by Alexandre Duret-Lutz.
4821 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

4824 refer to the correct file.
4825 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4826 the behavior of the third argument.
4827 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4828 correctly the behavior of the third argument. Document
4829 what the three macros that AU_DEFUN defines do. Fix
4830 warning message when the third argument includes $0
4831 (reported by Alexandre Duret-Lutz).
4833 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4834 Eric Sunshine <sunshine@sunshineco.com>
4835 Paul Eggert <eggert@twinsun.com>
4837 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4838 (AS_INIT): Output shell initialization there. Removed optional
4839 parameter. Expand _AS_SHELL_FN_SPY.
4840 (AS_INIT_WITH_SHELL_FN): Removed.
4841 (_AS_SHELL_FN_SPY): New macro.
4842 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4843 macros.
4844 (AS_SHELL_SANITIZE): Remove loop to find better shell
4845 and documentation for the parameter.
4846 (_AS_DETECT_BETTER_SHELL): Move it here.
4847 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
4848 (_AS_RUN): Move it here, support testing with eval.
4849 (AS_REQUIRE_SHELL_FN): Require shell functions when
4850 it is used.
4851 (_AS_LINENO_WORKS): Put around braces, we do not
4852 trigger the bash bug anymore.
4853 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4854 use AS_INIT_WITH_SHELL_FN.
4855 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4857 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4859 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

4863 (AU_DEFUN): Honor the third parameter, create autoupdate
4864 macros with AU_DEFINE.

4874 * lib/autoconf/status.m4: Remove FIXME.
4875 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
4876 that the macro is not present anymore in the updated
4877 configure.ac.
4878 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
4879 of autoupdate.

4884 copyright years.
4885 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4886 2003 (except 1997) to the list of copyright years. This undoes
4887 the 2003-05-22 change, which removed the older years from the list.
4888 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4890 2004-01-27 Gary V. Vaughan <gary@gnu.org>

4896 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4897 AC_PROG_GREP.
4898 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4899 egrep and fgrep respectively if $GREP -E/-F don't work.
4900 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4901 _AC_PROG_GREP, and AC_PROG_SED.
4902 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4903 longest input length accepted by a command.
4904 (AC_PROG_SED): Use it.
4905 * doc/autoconf.texi (Particular Programs): Document the changes.
4906 * NEWS: Updated.
4908 2004-01-27 Paul Eggert <eggert@twinsun.com>
4910 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

4912 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
4913 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
4915 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4916 bin/autoconf.in, config/Makefile.in, config/config.guess,
4917 config/config.sub, config/install-sh, config/mdate-sh,

4930 sources.
4932 2004-01-26 Paul Eggert <eggert@twinsun.com>
4934 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4935 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4936 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4937 not <inttypes.h>. Problem reported by Tim Mooney in
4938 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4939 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4940 Likewise.
4942 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4943 otherwise "make check" fails because it forbids cmp (I guess
4944 because cmp treats files as binary on DOS-like systems).
4946 * tests/mktests.sh: Update copyright date to 2004, since some tests
4947 have changed in 2004.
4949 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4951 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4952 non-truncating sed or gsed program in PATH.
4953 * tests/acprograms.at: Add it.
4954 * doc/autoconf.texi (Particular Programs): Document it.
4955 * NEWS: Updated.
4957 2004-01-15 Paul Eggert <eggert@twinsun.com>
4959 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4960 -std1 disables some useful extensions on Tru64. Problem reported
4961 by N. Lichtmaier in
4962 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4964 2004-01-14 Paul Eggert <eggert@twinsun.com>
4966 * doc/autoconf.texi (Programming in M4sh): Document that
4967 AS_MKDIR_P succeeds if the destination is a symbolic link
4968 to an existing directory.
4969 (Limitations of Usual Tools): Note that mkdir -p might not
4970 succeed on symlinks to directories.

4990 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4991 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4992 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4993 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4994 AC_COMPILE_IFELSE, since we now assume our caller invokes
4995 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4996 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4997 of AC_RUN_IFELSE; this avoids the warning mentioned above.

5000 2004-01-07 Paul Eggert <eggert@twinsun.com>
5002 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5003 `"'...'"`, as it's confusing (and I suspect it may not work on
5004 some platforms). The code was incorrect anyway, as it assumed
5005 that \$ evaluated to itself in that context. Reported by
5006 Alexandre Duret-Lutz.
5008 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

5060 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5061 -c -o might not work. From a suggestion by Kevin Ryde.
5062 (C Compiler, Generating Sources, Limitations
5063 of Usual Tools, Limitations of Make, Making testsuite Scripts):

5119 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
5120 does not work.
5121 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

5140 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

5458 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
5459 have been created when invoking the compiler.
5460 * tests/fortran.at (GNU Fortran 77): Quote $G77.
5462 2003-09-29 Akim Demaille <akim@epita.fr>
5464 Version 2.57e.
5466 * config/mkinstalldirs: Upgrade.

5470 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
5471 Problem reported by Lars J. Aas in
5472 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
5473 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5474 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5475 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5477 2003-09-26 Akim Demaille <akim@epita.fr>
5479 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5480 directory for AC_CONFIG_COMMANDS' first argument exists.
5481 This makes valid the invocation of _AC_SRCPATH that follows.
5482 Reported by Eric Sunshine.
5483 * doc/autoconf.texi (Configuration Commands): Adjust.
5485 2003-09-26 Akim Demaille <akim@epita.fr>
5487 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5488 Reported by Ralf Corsepius.
5490 2003-09-26 Akim Demaille <akim@epita.fr>
5492 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5493 arguments.
5494 Actually, use AU_ALIAS.
5495 From Bruno Haible.
5497 2003-09-26 Paul Eggert <eggert@twinsun.com>
5499 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
5500 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
5501 Problem reported by Eric Sunshine in:

5506 The test suite are sometimes assigning timings incorrectly.
5507 Reported by Henk Krus.
5508 Diagnosed by Nicolas Joly.
5510 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5511 AT_help_all.
5512 Instead of making AT_help a sequence of assignments to grow
5513 $at_help_all, just make AT_help_all be the growing contents of
5514 $at_help_all, and make a single assignment in...
5515 (AT_INIT): here.
5516 (at_times_skip): Flip the meaning and rename as...
5517 (at_times_p): this.
5518 (AT_INIT): When summarizing the test that ran, remove
5519 $at_times_file after use, and check it is present before trying to
5520 use it.
5522 2003-09-25 Akim Demaille <akim@epita.fr>
5524 Version 2.57d.
5526 * bin/Makefile.am (edit): Handle '@configure_input@'.
5527 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5528 (ifnames): chmod -w.
5529 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5530 executables, not bin/ executables! Otherwise all the magic needed
5531 to find non installed files is turned off. This caused a failure
5532 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5533 as found in its environment (sent by tests/autoreconf): pointing
5534 to bin/autom4te that could not find its files.
5535 * tests/mktests.sh: Force the replacement of generated files, for
5536 the sake of "mv" program that are interactive when overwriting a
5537 -w file.
5538 * config/install-sh: Upgrade from CVS Automake.
5540 2003-09-23 Paul Eggert <eggert@twinsun.com>
5542 * doc/autoconf.texi (Limitations of Builtins): Document test -h
5543 versus test -L issues.
5545 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
5546 Paul Eggert <eggert@twinsun.com>
5548 Trivial change to support GCC's configuration procedure.
5549 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5550 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5551 about inconsistency if the preprocessor is set to give errors for
5552 any warning.
5553 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5555 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
5557 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
5558 and XFile.pm from Automake.

5561 2003-09-12 Akim Demaille <akim@epita.fr>
5563 Version 2.57c.
5565 2003-09-12 Akim Demaille <akim@epita.fr>
5567 * config/config.guess, config/config.sub, config/missing,
5568 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
5569 from masters.
5571 2003-09-12 Akim Demaille <akim@epita.fr>
5573 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5574 not asm/types.h.
5576 2003-09-11 Akim Demaille <akim@epita.fr>
5578 * doc/autoconf.texi (Header Portability): linux/random.h.
5579 From Peter Hendrickson.
5581 2003-09-10 Akim Demaille <akim@epita.fr>
5583 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5584 willing to edit the output files.
5586 2003-09-10 Akim Demaille <akim@epita.fr>
5588 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5589 and AC_FC_FREEFORM.
5590 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5591 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
5593 2003-09-09 Akim Demaille <akim@epita.fr>
5595 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
5596 Reported by Gary Vaughan.

5602 trailing files.
5604 2003-09-07 Paul Eggert <eggert@twinsun.com>
5606 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
5607 Improve the accuracy of the wording about obsolescence.
5608 From a suggestion by Ian Lance Taylor in
5609 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5611 2003-09-05 Paul Eggert <eggert@twinsun.com>
5613 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5614 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5616 2003-09-04 Akim Demaille <akim@epita.fr>
5618 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5619 AC_FUNC_WAIT3.
5621 2003-09-04 Akim Demaille <akim@epita.fr>
5623 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5624 (freeze): When exiting, use $exit_code.
5625 * lib/autoconf/fortran.m4: Comment changes.
5627 2003-09-04 Akim Demaille <akim@epita.fr>
5629 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5631 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5633 Add support for newer Fortran dialects. The F77 interface is
5634 unchanged, and continues to support Fortran 77. New FC macros
5635 correspond to all the old F77 macros, with output variables FC,
5636 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5637 available dialect, but older dialects can be specified. There are
5638 new macros AC_FC_SRCEXT to set the source extension, and
5639 AC_FC_FREEFORM to accept free-form source files.
5641 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5642 New macros.
5643 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

5658 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
5659 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5660 Rewrite in terms of the above.
5661 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5662 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
5663 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
5664 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
5666 2003-09-02 Paul Eggert <eggert@twinsun.com>
5668 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5669 Document problems with timestamp resolution that 'make', 'cp -p', and
5670 'touch -r' have.
5672 2003-08-27 Akim Demaille <akim@epita.fr>
5674 * tests/m4sugar.at (cross_warning): Make sure to enable the
5675 output, so that we can track spurious m4sugar output.
5676 * tests/local.at: Require 2.57.
5677 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5678 are defaulted by AT_CHECK anyway.
5679 Use AT_CHECK_AUTOM4TE.
5680 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5681 missing dnl.
5683 2003-08-27 Akim Demaille <akim@epita.fr>
5685 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5686 when -Wobsolete is set.
5687 Set it on by default.
5688 Suggested by Klee Dienes.

5765 2003-08-21 Akim Demaille <akim@epita.fr>
5767 First stab at preserving warnings between calls to autom4te,
5768 including when the cache is used.
5770 There are still several issues: (i) there are too many runs of m4
5771 (one for include, one for warnings, and some more), (ii) warnings
5772 spreading on several lines are not handled gracefully, (iii) the
5773 code meant to have the call stack display for errors does not work
5774 (its handling should move from m4 to autom4te).
5776 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5777 Use them.
5778 (@preselect): Add m4_warn.
5779 ($exit_status): Remove, use $exit_code.
5780 ($help): Use Autom4te::ChannelDefs::usage.
5781 (&handle_m4): No longer define the m4_warnings.
5782 At each run, extract and report the warnings.
5783 Always cache the result, including if the exit status is on
5784 failure, since if nothing changes, we should result in the same
5785 failure, hence we can use the cache.
5786 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5787 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5788 Remove.
5789 (m4_warn): Redefine as a do-nothing: it is its invocation that
5790 matters, as warnings are now reported via traces.
5791 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5792 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5793 the latter reveals calls to the former.
5795 Adjust the tests.
5797 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5799 2003-08-21 Akim Demaille <akim@epita.fr>
5801 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

5806 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5807 forward order.
5808 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5809 (&parse_warnings): Accept a list of warning requests.
5810 (&usage): Return a string, not a side effect.
5811 (cross): New warning category.
5813 2003-08-21 Akim Demaille <akim@epita.fr>
5815 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5816 (&require_configure_ac): Accept an optional directory argument.
5817 ($configure_ac): Remove.
5818 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5819 (&catfile): Remove.
5820 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5821 * bin/autoscan.in: Adjust.
5823 2003-08-20 Akim Demaille <akim@epita.fr>
5825 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5826 Reported by Alexandre Duret-Lutz.
5828 2003-08-20 Akim Demaille <akim@epita.fr>
5830 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5831 * bin/autom4te: Adjust.
5832 In particular, be Autoconf tools are really silent when properly
5833 working, bind the verbosity of the 'note' channel to $verbose.
5834 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5835 (&xsystem, &contents): Remove, since they are exported by...
5836 * lib/Autom4te/FileUtils.pm: this.
5837 More perldoc.
5838 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5839 * lib/Autom4te/FileUtils.pm: here.
5841 2003-08-20 Akim Demaille <akim@epita.fr>
5843 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5844 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

5896 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5897 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5898 shorter column three. Add DESCRIPTION to log file content.
5900 2003-08-13 Derek Price <derek@ximbiot.com>
5902 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

5933 2003-07-06 Bill Clarke <llib@computer.org>
5935 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5936 'long', not 'int', for benefit of Sun's recent C++ compilers
5937 (trivial change). See:
5938 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5939 (This really should be 'intptr_t', not 'long', but that would
5940 take more work.)
5942 2003-06-25 Akim Demaille <akim@epita.fr>
5944 * lib/Makefile.am (autom4te.cfg): Make it read only.
5945 Depend on Makefile since it contains substitutions.
5946 From Paolo Bonzini.
5947 * lib/autom4te.in (args): Add local.at? for Autotest args.
5948 This change was made on autom4te.cfg which is generated.
5949 Reported by Raja R. Harinath.
5951 2003-06-25 Akim Demaille <akim@epita.fr>
5953 * doc/autoconf.texi (Header Portability): sys/mount.h.
5954 From Gareth McCaughan.
5956 2003-06-23 Akim Demaille <akim@epita.fr>
5958 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5959 not all of them. This fixes 1. the fact that when testing
5960 Autoconf there are many many config.log, 2. the incorrect use of
5961 top_srcdir to find config.log.
5962 Don't mix the detailed output of failed test with the summary of
5963 failures. Rather, append detailed log afterwards.
5965 2003-06-23 Akim Demaille <akim@epita.fr>
5967 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5968 always run: output config.log on $at_group_log.
5970 2003-06-23 Akim Demaille <akim@epita.fr>
5972 * tests/torture.at (#define header templates): Don't use quotes in
5973 C++ comments as it puzzles Emacs' sh font-lock-mode.
5975 2003-06-23 Akim Demaille <akim@epita.fr>
5977 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5978 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5979 * tests/atspecific.m4: Rename as...
5980 * tests/local.at: This.
5981 * tests/suite.at: Move the globals into...
5982 * tests/local.at: here.
5983 * tests/Makefile.am: Adjust.
5984 * doc/autoconf.texi (testsuite Scripts): Adjust.
5986 2003-06-21 Kevin Ryde <user42@zip.com.au>
5988 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5989 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5990 ensuring we add -std1 for full-ANSI.
5992 * doc/autoconf.texi (hdrindex): New macro.
5993 Add index entries for portability of various standard header files.
5995 2003-06-20 Akim Demaille <akim@epita.fr>
5997 * configure.ac: Bump to 2.57b.
5999 2003-06-20 Akim Demaille <akim@epita.fr>
6001 Version 2.57a.
6003 2003-06-20 Akim Demaille <akim@epita.fr>
6005 * bin/autom4te.in: Don't rely on $HOME being defined.
6006 Reported by Marc Espie as PR/233.
6008 2003-06-20 Akim Demaille <akim@epita.fr>
6010 * lib/autotest/general.m4: Use at_times_file only if used.
6011 From Nicolas Joly.
6013 2003-06-20 Akim Demaille <akim@epita.fr>
6015 * config/config.guess, config/config.sub, config/elisp-comp,
6016 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
6017 Update from masters.
6019 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6021 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6022 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6023 (TEST_SCRIPT): New diversion.
6024 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6025 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6026 (AT_INIT): Support for expected failures.
6028 2003-06-02 Akim Demaille <akim@epita.fr>
6030 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6031 changes.
6032 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6033 Autoconf nor Automake.
6034 (&contents): New, from Automake.
6035 PODify.
6037 2003-05-28 Paul Eggert <eggert@twinsun.com>
6039 * NEWS, doc/autoconf.texi (Particular Functions),
6040 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6041 is the inverse of localtime.
6043 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6045 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6046 (handle_exec_errors): New function. Work around $! being
6047 altered by WEXITSTATUS.
6048 (xqx, xsystem): Use handle_exec_errors.
6050 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6052 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6053 Do not call `_exit()', simply modify `$?'.
6054 (xsystem): Reset $! before running system, and check it afterward.
6055 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6056 63 for version mismatches.
6058 2003-05-23 Akim Demaille <akim@epita.fr>
6060 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6061 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6062 the middle of a line).
6063 * lib/m4sugar/m4sugar.m4: Likewise.
6064 Remove useless spaces in comments.
6066 2003-05-23 Akim Demaille <akim@epita.fr>
6068 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6069 exit 63, so that we (or Automake's "missing") can tell the
6070 difference with a plain failure.
6071 * doc/autoconf.texi (Notices): Adjust.
6073 2003-05-23 Akim Demaille <akim@epita.fr>
6075 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6076 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6077 White spaces cleanup.
6079 2003-05-22 Jim Meyering <jim@meyering.net>
6080 Paul Eggert <eggert@twinsun.com>
6082 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6083 Remove `#include <stdlib.h>' from the list; we should never
6084 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6085 resulting namespace pollution would cause other tests to fail.
6086 Configure scripts run with some older versions of g++ and HP's
6087 aCC would fail due to such an #include. Problems reported by
6088 Matthew Mueller in <http://bugs.debian.org/120704> and by
6089 Keith Bostic in
6090 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6091 In the test, use the test declaration before including <stdlib.h>,
6092 as that's closer to how it'll be used.
6094 2003-05-23 Akim Demaille <akim@epita.fr>
6096 * doc/autoconf.texi (Header Portability): ucred.h.
6097 From Ian Redfern.
6099 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6101 Overhaul Autotest's logging: generate separate log files
6102 in testsuite.dir/NNN/testsuite.log, and append them to
6103 testsuite.log instead of re-running the test verbosely.
6105 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6106 file descriptor, write 0 to at_status_file instead of setting
6107 at_status=0, initialize some new variables (at_status_file,
6108 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6109 to rerun the tests, instead append the at_group_log to the
6110 at_suite_log when a test fails.
6111 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6112 with the AS_MESSAGE_LOG_FD redirected to stdout.
6113 (AT_CLEANUP): save the output status in $at_status_file
6114 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6115 its original place.
6116 (AT_CHECK): since tests are run with a redirected stdout,
6117 and used to be re-run in verbose mode, turn some $at_verbose
6118 into echo, and don't redirect the output of testing stdout
6119 and stderr.
6121 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6122 the name of the debugging directory and information about
6123 its contents.
6125 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6127 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6128 parameter.

6198 Reported by Sander Niemeijer.
6199 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

6201 AC_INCLUDES_DEFAULT.
6203 2003-05-17 Akim Demaille <akim@epita.fr>

6240 and truncate.
6242 2003-05-06 Akim Demaille <akim@epita.fr>
6244 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6245 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6246 by aclocal.m4 is changed it might require the importing of another
6247 m4 extension file, i.e., aclocal must be run.
6249 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6250 (&parse_args): Use --force with aclocal if required and supported.
6251 (&autoreconf_current_directory): Use &run_aclocal.

6258 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6259 argument instead of a file name, so that the request file remains
6260 open during the whole autom4te run.
6261 ($icache_file): New.
6262 (&freeze): Lock the $icache_file.
6264 2003-04-29 Derek Price <derek@ximbiot.com>
6266 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6267 seperator with m4_append_uniq(). It doesn't work.
6268 (AT_CLEANUP): Add `;' to end of at_help_all.
6269 (AT_INIT): Allow --keywords to be specified more than once. When
6270 grepping $at_help_all for keywords, use the field and keyword
6271 seperators to ensure a complete keyword match. Alter at_prev handling
6272 to support the new --keywords behavior.
6274 2003-04-27 Karl Berry <karl@freefriends.org>
6276 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6277 align better with others. I also made some of the individual
6278 entries on one line, for brevity and to make it easier for me to
6279 sort my dir-example file in the Texinfo distribution :).
6281 2003-04-12 Jim Meyering <jim@meyering.net>
6283 * NEWS: Mention the new macro.
6284 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

6322 (TEXI2DVI): Make it --batch.
6324 2003-03-31 Derek Price <derek@ximbiot.com>

6327 which removed the main loop.
6328 Thanks to Akim Demaille.
6330 2003-03-29 Akim Demaille <akim@epita.fr>

6333 that starts a GUI.
6334 From Ilya Zakharevich.
6336 2003-03-29 Akim Demaille <akim@epita.fr>
6338 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
6339 documentation to read is Autoconf's.
6340 Suggested by Paul Eggert.
6342 2003-03-28 Akim Demaille <akim@epita.fr>
6344 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest

6346 header causes problems.
6348 2003-03-28 Akim Demaille <akim@epita.fr>
6350 * tests/torture.at (Configuring subdirectories): Require aclocal
6351 1.4, otherwise the test fails, as it does support configure.ac.
6352 This fixes the "test 40 failed" bug reports.
6354 2003-03-28 Akim Demaille <akim@epita.fr>
6356 * doc/autoconf.texi (C Compiler): `#line' portability.

6387 2003-03-26 Derek Price <derek@ximbiot.com>
6389 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

6422 about `$<' in inference rules, it was a bogus interpretation of
6423 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
6424 Tru64 make in the "target lookup" section.
6425 (Automake): Automake 1.5+ no longer requires special tools to be
6426 present on the developer's host.
6428 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
6430 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
6431 to a shell that can handle redirection or quoting correctly.

6434 * bin/autom4te.in (BEGIN): Likewise.
6435 * bin/autoreconf.in (BEGIN): Likewise.
6436 * bin/autoscan.in (BEGIN): Likewise.

6442 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
6443 to cope with DOS-style absolute paths, when constructing
6444 ${ac_make}.
6446 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6447 When constructing paths with IFS=:, quote the path. If we're
6448 constructing a DOS-style absolute path, we don't want to split it
6449 on the colon.
6451 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
6452 in description.
6454 2003-02-25 Pavel Roskin <proski@gnu.org>

6464 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
6466 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
6467 to fix a mismatch between example and discussion.
6469 2003-02-24 Kevin Ryde <user42@zip.com.au>
6471 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6472 format starting with "-".
6474 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6476 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6477 is not portable inside Makefile.
6479 2003-02-20 Akim Demaille <akim@epita.fr>
6481 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6482 compiler says yeah, but preproc says nope, compiler is right.
6483 Conversely, prompt the reader to send a bug report to the
6484 maintainers of the package, not of Autoconf.
6486 2003-02-20 Klee Dienes <kdienes@apple.com>
6488 * bin/autoreconf.in (autoreconf_current_directory): Properly

6494 $ac_prefix_program.
6495 From Larry Jones.
6497 2002-12-23 Paul Eggert <eggert@twinsun.com>
6499 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6500 innocuous variant befor including <limits.h> or <assert.h>. This
6501 works around a bug reported by Albert Chin: HP-UX 11i
6502 (and earlier versions) have a <limits.h> that declares
6503 gettimeofday and many other functions.
6505 2002-12-03 Paul Eggert <eggert@twinsun.com>
6507 Version 2.57.
6509 * NEWS, configure.ac: Update version.
6511 * doc/fdl.texi: Upgrade to FDL version 1.2.
6513 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6514 nontrivially in main's body, so that f's external declaration is
6515 not optimized away in AIX. This should fix the bug reported by
6516 Martin Frydl in
6517 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6519 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6520 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6521 defined, to support freestanding compilers. This should fix the
6522 bug reported by Momchil Velkov in
6523 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6525 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6526 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

6531 * Makefile.maint (www-gnu): New macro.
6532 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6533 the location has moved.
6535 2002-12-02 Martin Frydl <martin@systinet.com>
6537 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6538 \(.*\) match is too long and there is something more to be checked.
6539 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
6541 2002-11-15 Akim Demaille <akim@epita.fr>

6548 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
6549 * configure.ac (AM_INIT_AUTOMAKE): here.
6550 Require 1.7.1.
6552 2002-11-14 Akim Demaille <akim@epita.fr>
6554 Version 2.55.
6556 * config/config.guess, config/config.sub, config/install-sh:
6557 Update from masters.
6559 2002-11-14 Akim Demaille <akim@epita.fr>
6561 * Makefile.maint: Sync with Bison, i.e.:
6562 (po-check): Scan .l and .y files instead of the
6563 .c and the .h files that they generate. This fixes the bug
6564 reported by Tim Van Holder in:
6565 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6566 Look for N_ as well as for _. Try to avoid matching #define for
6567 N_ and _.
6568 From Paul Eggert.
6570 2002-11-14 Akim Demaille <akim@epita.fr>
6572 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6573 From Paul Eggert and Albert Chin-A-Young.
6575 2002-11-14 Akim Demaille <akim@epita.fr>
6577 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6578 From Paul Eggert and Albert Chin-A-Young.
6580 2002-11-14 Kevin Ryde <user42@zip.com.au>
6582 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6583 than assigning in main, to avoid HP cc +O3 optimizing it away.
6585 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6587 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6588 option. Process --recheck after parsing all options. Pass -q
6589 option to configure on --recheck.
6590 (AC_OUTPUT): Pass -q from configure to config.status.
6591 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6592 arguments to record.
6593 * doc/autoconf.texi (config.status Invocation): Document
6594 config.status -q option.
6596 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

6599 Makefile.in if Makefile.am exists.

6601 output AC_CONFIG_FILES if no Makefiles were found.
6603 2002-11-07 Akim Demaille <akim@epita.fr>

6610 2002-11-06 Akim Demaille <akim@epita.fr>
6612 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
6613 declaration in extern "C" too.

6618 * tests/torture.at (Configuring subdirectories): Don't use grep
6619 -w.
6620 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
6621 Reported by Ezra Peisach.
6623 2002-11-05 Akim Demaille <akim@epita.fr>
6625 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6626 Remove.
6627 We _have_ to stop using the old compatibility scheme that tried to
6628 avoid useless backslashes because Libtool 1.4.3 contains a
6629 AC_DEFINE([error_t], [int],
6630 [Define to a type to use for \`error_t' if it is not
6631 otherwise available.])
6632 We _have_ to quote the single quote and backslashes with \. The
6633 old compatibility scheme saw that ` was backslashed, and therefore
6634 did not quote the single quote. Hence before this patch, Autoconf
6635 was not compatible with Libtool.
6637 2002-11-04 Paul Eggert <eggert@twinsun.com>
6639 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
6640 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
6641 LC_NAME, LC_PAPER, LC_TELEPHONE.

6644 2002-11-04 Akim Demaille <akim@epita.fr>
6646 Version 2.54c.
6648 * Makefile.maint (update, cvs-update, po-update, do-po-update):

6654 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
6655 from...
6656 (&autoreconf): here.
6657 ($help, $make, &parse_args, &autoreconf_current_directory):
6658 Support -m/--make.
6659 * doc/autoconf.texi (autoreconf Invocation): Adjust.

6677 2002-10-31 Akim Demaille <akim@epita.fr>
6679 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6680 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6681 Make variable, not a shell variable.
6682 Suggested by Bruno Haible.
6684 2002-10-31 Akim Demaille <akim@epita.fr>
6686 * bin/autom4te.in (load_configuration): Reject #args out of any
6687 language.
6689 2002-10-31 Akim Demaille <akim@epita.fr>
6691 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

6703 Suggested by Tim van Holder.

6707 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
6708 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
6709 Problem reported by Bruno Haible.
6711 2002-10-29 Akim Demaille <akim@epita.fr>
6713 * doc/autoconf.texi (Header Templates): Put also in words what the
6714 pictures says to assist free style readers.
6715 (Customizing autom4te): s/--cache=/--cache /.
6717 2002-10-29 Akim Demaille <akim@epita.fr>
6719 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
6720 sys/wait.h.

6945 `$ac_configure_args'.

6967 2002-10-22 Akim Demaille <akim@epita.fr>
6969 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
6970 are a few warnings.
6971 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
6972 Quote for Perl '' strings, not "".
6973 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
6974 strings.
6976 2002-10-22 Akim Demaille <akim@epita.fr>
6978 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
6979 characters is a syntax warning now.

6986 `@', to tickle Perl's lists.
6987 Reported by Carlos Velasco.
6989 2002-10-18 Akim Demaille <akim@epita.fr>

7001 2002-10-17 Akim Demaille <akim@epita.fr>
7003 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.

7024 Because of caching, some files that no longer exist and are no
7025 longer required can still cause errors.
7026 Reported by Alexandre Duret-Lutz.
7028 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7029 to frozen files in @ARGV, as @ARGV must remain being a list of
7030 files. Rather, at M4 call sites, use this...
7031 (&files_to_options): New function.
7032 (&freeze): Use &error.
7033 (&up_to_date): If a file that was included according to the cache
7034 is no longer there, then the output is out dated.
7035 (&main): Don't even check whether a file is up to date is anyway
7036 --force is given.
7037 * tests/tools.at (autom4te cache): New.
7039 2002-10-16 Akim Demaille <akim@epita.fr>
7041 * bin/autoconf.as: Kill dead options.

7043 * bin/autoreconf.in (&parse_args): Remove dead options.
7044 Factor some code.
7045 (&autoreconf): Report the directories we enter *and leave*, so
7046 that error messages can be easily located, and use GNU Make
7047 format, so that Emacs' compile mode understands us.
7048 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7049 if some file was changed instead of `print'.
7050 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
7051 (&parse_args): Remove the dead options.

7063 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)

7084 file name to enable parallel executions.
7085 From Sam Varshavchik.
7087 2002-10-08 Akim Demaille <akim@epita.fr>
7089 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7090 aclocal invocation, as Gettext macros might not be visible to
7091 aclocal.
7092 Instead of blindly running autopoint, scan configure.ac (not the
7093 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7094 Reported by Paul D. Smith.
7096 2002-10-08 Paul Eggert <eggert@twinsun.com>
7098 Work around problems found when POSIXLY_CORRECT=1 is set.
7099 None of this seems to have anything to do with POSIX, really,
7100 but it's how Perl getopt works.
7101 * bin/autom4te.in (parse_args): Configure GetOpt with
7102 "permute", too.
7103 * doc/autoconf.texi (Invoking autom4te):
7104 --warning -> --warnings.

7124 2002-09-28 Akim Demaille <akim@epita.fr>
7126 * tests/torture.at (Configuring subdirectories): Be robust to
7127 users who use config.site to require for a cache: in this case,
7128 the two last configure runs, using two different sets of
7129 arguments, trigger a legitimate error.
7131 2002-09-28 Akim Demaille <akim@epita.fr>

7134 New.

7147 (tm_zone): Move their rules to...
7148 * lib/autoconf/types.m4: here, using AN_ macros.
7149 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7150 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7151 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7152 * lib/autoconf/programs.m4: here.

7164 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7165 (.m4.m4f): Don't pass --prepend-include, since that's done by
7166 tests/autom4te itself.
7167 * lib/autoscan/Makefile.am: Include freeze.mk.
7168 (autoscan.list): New target --this file is no longer a source.
7169 (autoscan.pre): New file.
7171 2002-09-28 Akim Demaille <akim@epita.fr>
7173 * bin/autoscan.in (@kinds): Make them singular.
7174 Adjust all uses.
7175 (&init_tables): When --debug, report the list of rules to ease
7176 tracking changes in autoscan.list.
7177 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7179 2002-09-28 Akim Demaille <akim@epita.fr>

7191 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7192 `functions' line is now prefixed with `function:'.
7193 * bin/autoscan.in (&init_tables): Adjust.
7195 2002-09-28 Akim Demaille <akim@epita.fr>
7197 From now on, autoscan files must always map a macro name to a
7198 word: there is no `default' macro for autoscan.
7200 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7201 all.
7202 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7203 explicit.
7205 2002-09-28 Akim Demaille <akim@epita.fr>
7207 * bin/autoscan.in (%c_keywords): Remove.
7208 (&used): Keep only track of the words we might be interested in.

7239 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7240 Reported by Ralf Corsepius.
7241 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7243 2002-09-26 Akim Demaille <akim@epita.fr>
7245 Single suffix rules and seperated dependencies are not portable.
7247 * doc/autoconf.texi (Installation Directory Variables): Update.

7270 Reported by Ralf Corsepius.

7293 Suggested by Guido Draheim.
7295 2002-09-13 Akim Demaille <akim@epita.fr>
7297 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals

7301 2002-09-12 Akim Demaille <akim@epita.fr>
7303 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7304 the lists.
7306 2002-09-12 Akim Demaille <akim@epita.fr>
7308 * doc/autoconf.texi (Defining Symbols): Present two different
7309 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

7314 * doc/autoconf.texi: Review grammar and punctuation.

7319 grammatical typos.
7320 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7321 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7322 is obsolescent.
7324 2002-09-11 Akim Demaille <akim@epita.fr>
7326 * doc/autoconf.texi (Questions): Rename as...

7342 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7343 `duplicates', since the algorithm was too naive and could keep
7344 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7345 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7346 Reported by Ralf Corsepius.

7357 directory definition.
7358 Reported by Andreas Schwab and Jim Meyering.
7360 2002-09-06 Akim Demaille <akim@epita.fr>

7363 precious variables are.
7364 Suggested by Pontus Skoeld.
7366 2002-09-05 Akim Demaille <akim@epita.fr>
7368 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7369 (ifnames, autoscan, autom4te): Since we don't only depend on
7370 configure.ac variables (such as VERSION etc.), but also on prefix
7371 and so forth, depend on Makefile, not configure.ac.
7372 Reported by Alexandre Duret-Lutz.
7373 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7375 2002-09-05 Kevin Ryde <user42@zip.com.au>
7377 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes

7395 * configure.ac: Bump to 2.53d.

7397 as of today, on Automake's team suggestion.
7399 2002-09-03 Akim Demaille <akim@epita.fr>
7401 Version 2.53c.

7411 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7412 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7413 Also, tweak grammar: s/make sure to/be sure to/.
7415 2002-09-02 Paul Eggert <eggert@twinsun.com>
7417 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7418 directory names are generally preferable to physical names.
7420 2002-09-02 Akim Demaille <akim@epita.fr>
7422 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7423 Reported by Raja R. Harinath.
7424 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7425 * bin/autoupdate.in: Use error instead of die.
7427 2002-09-01 Paul Eggert <eggert@twinsun.com>
7429 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7430 ordinary shell concatenation rather than echo+tr+sed command that
7431 runs afoul of a long-line-related sed bug in Solaris 8.
7433 * bin/autoheader.in (parse_args): --warning -> --warnings.
7435 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7436 stdout, as traditional "ls" does.
7437 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7438 _AC_COMPILER_EXEEXT_O): Likewise.
7439 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7441 * bin/autoconf.as: Add --prepend-include option. This patch was
7442 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7443 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7445 * bin/autoconf.in, configure: Regenerate.
7447 * doc/autoconf.texi (Special Shell Variables): Mention
7448 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7450 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7451 MAILPATH and set PS1, PS2, PS4 to default values, to work
7452 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7453 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7454 the Autoconf documentation specifies; fall back to "unset" only if
7455 this fails. Use a shell for-loop for this rather than an m4 loop,
7456 to shorten the output script.
7458 2002-08-30 Paul Eggert <eggert@twinsun.com>
7460 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7461 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7462 for the CDPATH problem. Document PWD.
7463 (Limitations of Builtins): Document the problem that "cd $foo" and
7464 "ls $foo" may refer to different directories in shells conforming
7465 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7466 example, since the old example is now out of date.
7468 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7469 FOO" and "ls FOO" talk about different directories; this catches
7470 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7471 spaghetti.
7473 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7474 of rolling our own unset.
7475 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7476 in practice we needn't worry about CDPATH if unset doesn't work.
7478 * Makefile.in, aclocal.m4, bin/Makefile.in,
7479 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7480 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7481 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7482 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7483 tests/Makefile.in: Regenerate with Automake 1.6.3.
7485 * config/config.guess, config/config.sub, config/mkinstalldirs:
7486 Update.
7488 * configure: Regenerate with self.
7490 2002-08-30 Kevin Ryde <user42@zip.com.au>
7492 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7493 default output.
7495 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7497 * bin/autom4te.in (Request::load): Correctly test for "do" read
7498 failure.
7500 2002-08-29 Akim Demaille <akim@epita.fr>
7502 * lib/Autom4te/General.pm (&xqx): New.
7503 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7504 hand, which is not portable.
7505 (&error): New.
7506 * bin/autom4te.in: Use them.
7507 Use &error instead of die.
7508 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7509 Adjust.
7511 2002-08-17 Paul Eggert <eggert@twinsun.com>
7513 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7514 default list of compilers to try, since it was long ago superseded
7515 by the ksh fc builtin. Suggested by Steven G. Johnson.
7517 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7519 * doc/autoconf.texi (Invoking autom4te): End the option table,
7520 fixing a bug introduced by the previous patch.
7521 (Limitations of Make): Add a 'target lookup' subentry in the
7522 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7524 2002-07-29 Mark D. Roth <roth@feep.net>
7526 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7527 options and use $AUTOM4TE_PATH.
7528 * doc/autoconf.texi: Remove documentation of autom4te
7529 --include-envvar and --site-macro-subdir options and document
7530 use of $AUTOM4TE_PATH.
7531 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7532 arguments from each language section.
7534 2002-07-29 Paul Eggert <eggert@twinsun.com>
7536 * doc/install.texi: Include copyright symbol in copyright notice.
7538 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7539 Replace with:
7540 (AM_MAKEINFOFLAGS): New macro.
7541 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7542 * Makefile.am (INSTALL): Use the new macros.
7543 Use -o rather than --output, since "missing" does not grok --output.
7545 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7547 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7548 comments do not always work. Never trust the exit status of
7549 `make -k'.
7551 2002-07-24 Kevin Ryde <user42@zip.com.au>
7553 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7554 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7556 2002-07-23 Paul Eggert <eggert@twinsun.com>
7558 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7559 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7560 apparently treats PATH="nonexistent" as if it contained ".".
7561 Bug reported by Stefan `Sec' Zehl.
7563 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7565 * doc/autoconf.texi (Limitations of Make): Mention the special
7566 handling of the obj/ directory by BSD make.
7568 2002-07-20 Kevin Ryde <user42@zip.com.au>
7570 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
7571 backslashes.
7573 2002-07-19 Akim Demaille <akim@epita.fr>

7582 2002-07-18 Akim Demaille <akim@epita.fr>
7584 Version 2.53b.
7586 2002-07-18 Akim Demaille <akim@epita.fr>
7588 * config/config.guess, config/config.sub: Update.
7590 2002-07-18 Akim Demaille <akim@epita.fr>
7592 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
7593 Automake's parts.

7596 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
7597 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
7599 2002-07-18 Akim Demaille <akim@epita.fr>,
7600 Alexandre Duret-Lutz <duret_g@epita.fr>
7602 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
7603 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

7612 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
7613 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the

7618 * lib/Autom4te/General.pm (find_file): Browse the directories in
7619 the order they are given.

7639 macro directory, remove note that include path directories are
7640 used in reverse order, and document --prepend-include option.
7641 * lib/autom4te.in: Use --prepend-include instead of --include.
7642 * tests/wrapsh.in: Use --prepend-include instead of --include.

7680 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
7682 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7683 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
7684 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
7685 so that Emacs setups GNU style for perl-mode and cperl-mode.
7687 2002-06-27 Paul Eggert <eggert@twinsun.com>
7689 * config/install-sh: Quote $src. Prefer || to test's -o option,
7690 as per "Limitations of Builtins".
7691 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7692 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7694 * tests/mktests.sh: Use grep instead of fgrep, as per
7695 "Limitations of Builtins".
7697 2002-06-15 Paul Eggert <eggert@twinsun.com>
7699 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7700 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7701 so that we consistently test the just-built programs.
7702 * tests/wrappl.as: Likewise.
7704 2002-06-12 Paul Eggert <eggert@twinsun.com>
7706 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
7707 name, so that symlinks to 'autoconf' work properly. Bug reported
7708 by Bruno Haible.
7709 * bin/autoheader.in (AUTOM4TE): Likewise.
7710 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7711 * bin/autoscan.in (autom4te): Likewise.
7712 * bin/autoupdate.in (autom4te): Likewise.
7714 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7715 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7716 on Solaris 2.5.1.
7718 2002-06-11 Andreas Schwab <schwab@suse.de>
7720 * doc/autoconf.texi: Add more dir entries.
7722 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7724 * bin/autom4te.in ($cache): Don't define using `$me', the name
7725 of the cache should not depend on the name under which autom4te
7726 was installed.
7728 2002-06-07 Akim Demaille <akim@epita.fr>
7730 * tests/tools.at (autoconf: forbidden tokens, basic)
7731 (autoconf: forbidden tokens, exceptions): Adjust to the change of
7732 words in autom4te.in.
7734 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7736 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7737 _AC_LANG_PROGRAM_C_F77_HOOKS.
7739 2002-06-07 Akim Demaille <akim@epita.fr>
7741 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
7742 rename as...
7743 (AC_REPLACE_FNMATCH): this.
7744 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
7745 AC_FUNC_FNMATCH_GNU.
7747 2002-06-07 Akim Demaille <akim@epita.fr>
7749 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7750 Rosetta Stone for Unix.
7752 2002-06-07 Akim Demaille <akim@epita.fr>
7754 * bin/autom4te.in (warn_forbidden): When rejecting a token,
7755 suggest m4_pattern_allow.
7756 Suggested by Adam J. Richter.
7758 2002-06-07 Akim Demaille <akim@epita.fr>
7760 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
7761 ac_config_libobj_dir.
7762 (AC_CONFIG_LIBOBJ_DIR): New.
7763 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
7764 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
7765 Use ac_config_libobj_dir to find the replacement files.
7766 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
7767 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
7768 (AC_REPLACE_FNMATCH_GNU): these.
7769 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
7770 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
7771 * tests/mktests.sh (ac_exclude_list): Don't check
7772 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
7774 2002-06-06 Paul Eggert <eggert@twinsun.com>
7776 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7777 if ln doesn't work.
7778 * NEWS: Likewise.
7779 * doc/autoconf.texi (Configuration Links): Likewise.
7780 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
7782 2002-06-05 Paul Eggert <eggert@twinsun.com>
7784 * config/config.guess, config/config.sub, config/texinfo.tex:
7785 Update from masters.
7787 2002-05-29 Paul Eggert <eggert@twinsun.com>
7789 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
7790 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
7791 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

7799 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
7800 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
7802 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
7803 * doc/autoconf.texi (Particular Programs): Document them.
7804 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
7805 * NEWS: Likewise.
7807 2002-05-27 Paul Eggert <eggert@twinsun.com>
7809 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
7810 * NEWS, doc/autoconf.texi (Particular Types): Document it.
7811 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
7812 instead of AC_MBSTATE_T, which never existed.
7814 2002-05-23 Akim Demaille <akim@epita.fr>
7816 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7817 version of Autoconf that is discussed.
7819 2002-05-22 Paul Eggert <eggert@twinsun.com>
7821 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7822 from the default list of compilers to try. Suggested by
7823 Kate Hedstrom.
7824 * NEWS: Document the above.
7825 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7827 2002-05-17 Paul Eggert <eggert@twinsun.com>
7829 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7830 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7831 This improves on an earlier suggestion by H. Peter Anvin.
7833 2002-05-16 Paul Eggert <eggert@twinsun.com>
7835 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7836 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7837 Both macros now accept an optional source-dir arg.
7838 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7840 * NEWS: Document this.
7841 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7843 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7844 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7845 not for GNU extensions; this undoes part of the 2000-11-03 change,
7846 reverting to 2.13-compatible behavior.
7847 Add new optional argument DIR.
7848 (AC_FUNC_FNMATCH_GNU): New macro.
7850 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7852 2002-05-08 Paul Eggert <eggert@twinsun.com>
7854 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7855 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7856 and it causes a 'test' syntax error if it fails.
7857 Bug reported by Stephen Gildea.
7859 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7860 If prototypes are supported, use them to check this at compile-time,
7861 instead of trying to check it at run-time. If we must do a run-time
7862 check, assume that setvbuf is standard when cross-compiling, as
7863 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7864 Bug reported by Paul D. Smith.
7866 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7867 argument specifying location of getloadavg.c. This removes a
7868 FIXME. This idea was taken from Jim Meyering's implementation in
7869 textutils.
7870 * doc/autoconf.texi (Particular Functions): Document this.
7871 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7872 that's what the code does; this fixes a bug reported by
7873 Paul D. Smith.
7875 2002-05-03 Akim Demaille <akim@epita.fr>
7877 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7878 autopoint instead of gettextize.
7879 ($uses_alocal): Rename as...
7880 ($uses_aclocal): this.
7881 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7882 Suggested by Bruno Haible.
7884 2002-05-03 Akim Demaille <akim@epita.fr>
7886 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7888 2002-04-29 Paul Eggert <eggert@twinsun.com>
7890 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7891 files to be 1 second older; just set them to be the same time.
7892 Also, sleep 1 second after the first aclocal, to work around
7893 problems with sub-second time stamps on the input files.
7895 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7897 * doc/autoconf.texi: Mention "set -e -x" lossage
7898 under node "Limitations of Builtins".
7900 2002-04-29 Akim Demaille <akim@epita.fr>
7902 * doc/install.texi: Better wording for setting variables when
7903 running configure.
7904 From Christian Cornelssen.
7906 2002-04-29 Akim Demaille <akim@epita.fr>
7908 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7909 of lack of $LINENO support, then the test will compare the $LINENO
7910 in testsuite vs. the lineno in the test file. This is wrong, of
7911 course.
7912 Be sure to protect it.
7913 Reported by Patrick Welche.
7915 2002-04-25 Akim Demaille <akim@epita.fr>
7917 * doc/autoconf.texi (Obsolete Macros): Typo.
7918 Reported by Vladimir Volovich.
7920 2002-04-25 Akim Demaille <akim@epita.fr>
7922 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7923 than some of the input files, hence, on the second run of aclocal,
7924 if some of its input are younger, make them older.
7925 Suggested by Paul Eggert.
7927 2002-04-25 Akim Demaille <akim@epita.fr>
7929 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7930 Thanks to Paul Eggert.
7932 2002-04-25 Akim Demaille <akim@epita.fr>
7934 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7935 and ac_subst_vars be sh variables containing the list of
7936 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7937 DEFAULT diversion.
7938 (_AC_INIT_PREPARE): Use them to log them.
7939 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7940 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7941 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7942 _AC_SUBST_FILES and _AC_SUBST_VARS.
7943 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7945 2002-04-24 Akim Demaille <akim@epita.fr>
7947 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7948 autoheader, so that automake does not complain about a missing
7949 config.h.in that was to be created.
7951 2002-04-23 Akim Demaille <akim@epita.fr>
7953 * bin/autoheader.in (parse_args): --warning takes an argument.
7954 Fixes PR/220.
7956 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7958 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
7959 and bb.out when cleaning up.

8003 Minor spelling and grammar fixes.
8005 * doc/autoconf.texi: Follow the outline suggested in the GNU
8006 Sample Texts sections of the Texinfo 4.2 manual. Most
8007 importantly, this makes sure that the copyright notices appear in
8008 all output formats. You probably need Texinfo 4.2 to generate
8009 the manual now.
8011 Fix some bugs when using "$@" when there might be zero positional
8012 arguments in cases where this matters.

8035 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8037 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

8042 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
8044 2002-04-10 Akim Demaille <akim@epita.fr>
8046 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8047 workaround for ${1+"$@"}.
8048 * doc/autoconf.texi (Shell Substitutions): Explain it.
8049 From Oliver Kiddle and Peter Stephenson.
8051 Have M4sh perform minimal shell sanitizing.
8053 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8054 part into...
8055 (_AS_PREPARE): this new macro.
8056 (AS_PREPARE): New.
8057 (AS_INIT): Invoke AS_SHELL_SANITIZE.
8058 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8060 Adjust Autoconf and Autotest.
8062 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8063 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8064 * lib/autotest/general.m4 (AT_INIT): Likewise.
8065 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8066 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8067 AS_SHELL_SANITIZE.
8069 Use this M4sh to generate Autoconf's shell scripts.
8071 * tests/wrapsh.as: New, precursor of wrapsh.in.
8072 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8073 on Autotest and M4sh.
8074 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8075 (wrapsh.in): New target.
8076 * bin/autoconf.as: New, precursor of autoconf.in.
8077 (autoconf.in): New target.
8079 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

8082 with indented comments in rules.
8084 2002-04-09 Andreas Schwab <schwab@suse.de>
8086 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
8087 ac_top_builddir when setting ac_abs_top_builddir.
8089 2002-04-06 Kevin Ryde <user42@zip.com.au>
8091 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
8092 (Portable Shell): Cross reference to Systemology.
8094 2002-04-05 Akim Demaille <akim@epita.fr>
8096 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8097 directories when descending in a SUBDIRS.
8098 Reported by Ezra Peisach.
8100 2002-04-04 Andreas Schwab <schwab@suse.de>
8102 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8103 contains no literal separators.
8105 2002-04-03 Akim Demaille <akim@epita.fr>
8107 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8108 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8109 Use dnl, not the KILL diversion.
8110 Extracted from...
8111 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8112 (AC_CONFIG_LINKS): here.
8113 Adjust.
8114 Don't use the KILL diversion, as it kills spurious output, which
8115 results in failures being hidden.
8116 Use m4_defn where appropriate.
8117 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8118 after the second argument.
8119 Use m4_defn.
8120 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8121 syntax, as it is provided by M4sugar.
8122 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
8124 2002-04-03 Andreas Schwab <schwab@suse.de>
8126 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
8127 expanded if $# <= 2.
8129 * bin/autoreconf.in (autoreconf): Run automake after rerunning
8130 aclocal.
8132 2002-04-03 Akim Demaille <akim@epita.fr>
8134 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
8135 (_AC_COMPILER_EXEEXT_REJECT): New.
8136 Also recognize *.bb and *.bbg as compilation byproducts.
8137 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
8138 (_AC_COMPILER_OBJEXT): Use them.
8139 Fixes Debian #138666.
8141 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
8143 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
8145 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
8146 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
8147 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
8148 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
8149 (AC_C_CONST): Same.
8150 (AC_C_INLINE): Same.
8151 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
8152 * doc/autoconf.texi, NEWS: Document.
8153 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
8154 AC_C_CROSS.

8159 _AS_MKDIR_P_PREPARE.
8161 2002-03-28 Kevin Ryde <user42@zip.com.au>
8163 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8164 to avoid versions of HP C which don't allow that.
8166 2002-03-27 Paul Eggert <eggert@twinsun.com>
8168 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8169 (AS_SHELL_SANITIZE): Invoke it.
8170 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
8172 2002-03-26 Akim Demaille <akim@epita.fr>
8174 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
8176 2002-03-26 Akim Demaille <akim@epita.fr>
8178 * doc/autoconf.texi (Introduction): The GNATS base moved.
8180 2002-03-25 Paul Eggert <eggert@twinsun.com>
8182 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8183 as POSIX requires, as it doesn't work with Zsh.
8184 * doc/autoconf.texi (Assignments): Document the problem.
8186 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8188 * doc/autoconf.texi (Limitations of Make): Mention more issue
8189 about VPATH, overriding of macros in sub-makes, and handling of
8190 SHELL.
8192 2002-03-21 Paul Eggert <eggert@twinsun.com>
8194 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8195 problem with here-document buffer boundaries.
8197 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8198 when reinvoking the shell, to work around problems with installers
8199 who put strange things like "cd" commands in their environments.
8201 2002-03-19 Akim Demaille <akim@epita.fr>
8203 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8204 From Aaron Ucko.
8206 2002-03-19 Akim Demaille <akim@epita.fr>
8208 * bin/autoscan.in (scan_file): Specify the location in `&used'
8209 invocations.
8210 From Nicolas Joly.
8212 2002-03-19 Akim Demaille <akim@epita.fr>
8214 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8215 From Nishio Futoshi.
8217 2002-03-19 Akim Demaille <akim@epita.fr>
8219 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8221 2002-03-18 Paul Eggert <eggert@twinsun.com>
8223 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8224 (Limitations of Usual Tools): Add mkdir section.
8226 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8227 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8228 back on AS_DIRNAME to compute prefixes otherwise; this is
8229 roughly what mkinstalldirs does. That way, we need not have
8230 our own filename disassembler. The old disassembler did not
8231 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8233 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8234 Create at_test_all by a series of assignments,
8235 not by a single assignment of a long string. The latter causes ksh
8236 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8237 presumably because of a buffer overrun.
8239 2002-03-14 Paul Eggert <eggert@twinsun.com>
8241 * lib/autotest/general.m4 (at_times_skip):
8242 Renamed from at_times. Now a boolean.
8243 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8244 says 'times: not found'.
8246 2002-03-14 Akim Demaille <akim@epita.fr>
8248 * bin/autoreconf.in (&study_gettextize): New.
8249 (&autoreconf): Handle newest gettextize.
8250 Rerun aclocal if needed.
8251 Suggested by Andreas Schwab.
8253 2002-03-13 Akim Demaille <akim@epita.fr>
8255 * doc/autoconf.texi (Special Shell Variables): More about IFS.
8257 2002-03-13 Akim Demaille <akim@epita.fr>
8259 * doc/autoconf.texi (Header Portability): New.
8260 Add information about stdint.h and inttypes.h from Paul Eggert.
8262 2002-03-13 Akim Demaille <akim@epita.fr>
8264 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8265 -p'.
8266 From Bob Proulx.
8268 2002-03-12 Akim Demaille <akim@epita.fr>
8270 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8271 m4_require.
8273 2002-03-11 Andreas Schwab <schwab@suse.de>
8275 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8276 does not do it if --with-lispdir is given.
8278 2002-03-08 Akim Demaille <akim@epita.fr>
8280 Version 2.53.
8282 2002-03-08 Akim Demaille <akim@epita.fr>
8284 * doc/autoconf.texi (Subdirectories): Clarify that the
8285 subdirectory should exist.
8287 2002-03-08 Akim Demaille <akim@epita.fr>
8289 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8291 2002-03-08 Akim Demaille <akim@epita.fr>
8293 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8294 aliases the actual variables, and modifications of the former
8295 affect the latter.
8297 2002-03-08 Akim Demaille <akim@epita.fr>
8299 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8300 because of C-c: have m4 output in tmp files, then mv them.
8302 2002-03-08 Akim Demaille <akim@epita.fr>
8304 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8305 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8306 * bin/ifnames.in: Copyright update.
8308 2002-03-08 Akim Demaille <akim@epita.fr>
8310 * doc/autoconf.texi (Invoking autom4te): New.
8312 2002-03-05 Akim Demaille <akim@epita.fr>
8314 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8315 Kevin Ryde.
8317 2002-03-05 Akim Demaille <akim@epita.fr>
8319 Version 2.52i.
8321 2002-03-04 Akim Demaille <akim@epita.fr>
8323 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8324 * lib/autoconf/general.m4 (AC_INIT): More informative error
8325 message for LIBOBJ.
8327 2002-03-04 Akim Demaille <akim@epita.fr>
8329 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8330 parallel builds.
8332 2002-03-04 Akim Demaille <akim@epita.fr>
8334 * doc/autoconf.texi (Transforming Names): Equality between target
8335 and host is irrelevant.
8336 (Specifying Names, Canonicalizing): Remove all references to the
8337 backward compatibility hooks. Rather, collect them all into...
8338 (Hosts and Cross-Compilation): this new section.
8339 * doc/install.texi (System Type): Ditto.
8340 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8341 that `--host' implies cross-compilation.
8343 2002-03-04 Akim Demaille <akim@epita.fr>
8345 * doc/autoconf.texi (Evaluation Macros): New.
8346 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8347 useless.
8348 (_m4_foreach): Define the variant with immediate evaluation so
8349 that it contains exactly the items, not an expression which
8350 evaluation is the current item.
8351 (m4_re_string, m4_re_word): Don't over quote them.
8353 2002-03-04 Akim Demaille <akim@epita.fr>
8355 Instead of having stacking `shift's evaluated at the end, let
8356 `foreach' loops immediately evaluate them.
8358 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8359 $*. This is the n-th time I change my mind, but hopefully this is
8360 the last...
8361 (m4_lquote): New.
8362 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8363 efficient.
8364 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8365 it was only a hack for m4_text_wrap.
8366 (m4_car2): Remove, replaced by...
8367 (m4_cdr): New.
8368 (_m4_foreach): Adjust.
8369 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8370 m4_bpatsubst for clarification.
8372 2002-03-04 Akim Demaille <akim@epita.fr>

8398 2002-02-25 Akim Demaille <akim@epita.fr>
8400 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
8401 From Akinori Musha.
8403 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
8405 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8406 translate \r\n to \n.

8419 2002-02-07 Akim Demaille <akim@epita.fr>
8421 Fix Autoconf PR/207:
8422 AC_PREFIX_PROGRAM fails with dashed program names
8424 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8425 variable when looking for the prefix program.
8426 Now it also works for shell variables.
8428 2002-02-07 Akim Demaille <akim@epita.fr>
8430 * doc/autoconf.texi (Limitations of Builtins): More about
8431 case/esac.
8433 2002-02-06 Akim Demaille <akim@epita.fr>
8435 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
8436 case/esac, some shells don't support it.
8437 Reported by Zack Weinberg.
8438 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
8440 2002-02-06 Akim Demaille <akim@epita.fr>
8442 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8443 sure not to introduce newlines in at_groups.
8444 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8446 2002-02-06 Akim Demaille <akim@epita.fr>
8448 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8449 is not available.
8451 2002-02-05 Paul Eggert <eggert@twinsun.com>
8453 * doc/autoconf.texi (Specific Compiler Characteristics):
8454 Describe HP-UX cc bug workaround more accurately.
8455 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
8456 not unsigned long.
8457 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8458 cross-compilers, too. This undoes some of the most recent change
8459 to this file.
8461 2002-02-05 Akim Demaille <akim@epita.fr>
8463 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8464 to make sure they are up to date when `check' is run.
8466 2002-02-05 Akim Demaille <akim@epita.fr>
8468 * doc/autoconf.texi (Making testsuite Scripts): Document
8469 package.m4.
8471 2002-02-05 Akim Demaille <akim@epita.fr>
8473 * lib/freeze.mk: New.
8475 2002-02-05 Akim Demaille <akim@epita.fr>
8477 Implement `autom4te --freeze'.
8479 * bin/autom4te.in (&freeze): New.
8480 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8481 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8483 2002-02-05 Akim Demaille <akim@epita.fr>
8485 * bin/autom4te.in (&parse_args): Implement `frozen files are
8486 optional are the sum of the previous files on the command line'.
8487 Also, pass `--reload-state=' on them, so...
8488 (handle_m4): don't.
8489 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8490 (M4sh): Rely on M4sugar.
8491 (Autotest, M4sh, M4sugar): Use frozen files.
8493 2002-01-31 Akim Demaille <akim@epita.fr>
8495 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8496 * doc/autoconf.texi (Initializing configure): Adjust.
8498 2002-01-30 Akim Demaille <akim@epita.fr>
8500 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8501 alphanumeric to `-' instead of `_'.
8503 2002-01-30 Akim Demaille <akim@epita.fr>
8505 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8506 for plain code, the other for cross-compilation code. The latter
8507 is now run with GCC only.
8508 * doc/autoconf.texi (Compilers and Preprocessors): New.
8510 2002-01-30 Akim Demaille <akim@epita.fr>
8512 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8513 values.
8514 * doc/autoconf.texi (Initializing configure): Explain how to
8515 change AC_INIT default values.
8517 2002-01-29 Akim Demaille <akim@epita.fr>
8519 * tests/torture.at (Configuring subdirectories): Use configure.in,
8520 so that aclocal 1.4 works.
8521 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8523 2002-01-28 Akim Demaille <akim@epita.fr>
8525 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8526 needs an argument.
8528 2002-01-28 Akim Demaille <akim@epita.fr>
8530 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8531 AUTOTEST_PATH *after* it was set.
8532 Don't put `.' in the PATH: the user should be precise and `./' if
8533 needed. In addition, given that the test suite does some `cd', if
8534 `.' is in the path, the `tested programs' sections will report
8535 programs found in the test suite's directory, while during the
8536 tests (performed in their own directory), these programs are no
8537 longer visible. In other words, the results is confusing and
8538 useless.
8539 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8541 2002-01-24 Akim Demaille <akim@epita.fr>
8543 Version 2.52g.
8545 2002-01-24 Akim Demaille <akim@epita.fr>
8547 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
8548 * doc/autoconf.texi: Finally add Akim as an author.
8550 2002-01-24 Akim Demaille <akim@epita.fr>
8552 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8553 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8554 Bourne. Use /bin/sh.
8555 From Andreas Buening.
8557 2002-01-24 Akim Demaille <akim@epita.fr>
8559 * config/config.guess, config/config.sub, config/texinfo.tex:
8560 Update from masters.
8562 2002-01-24 Akim Demaille <akim@epita.fr>
8564 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
8565 * config/auxdir.m4, config/cond.m4, config/depend.m4,
8566 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
8567 * config/missing.m4, config/sanity.m4, config/select.m4,
8568 * config/strip.m4: Remove, to ease sync'ing with any version of
8569 Automake.
8571 2002-01-24 Akim Demaille <akim@epita.fr>
8573 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8574 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
8575 Reported by Geir Ove Myhr.
8577 2002-01-21 Akim Demaille <akim@epita.fr>
8579 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
8581 2002-01-21 Akim Demaille <akim@epita.fr>
8583 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8584 message on invalid options.
8585 * bin/autom4te.in (parse_args): Don't use
8586 Autoconf::General::getopt with non valid options.
8588 2002-01-17 Jim Meyering <meyering@lucent.com>
8590 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8591 $ac_cv_exeext so we don't use an old, invalid, cached value.
8593 2002-01-11 Akim Demaille <akim@epita.fr>
8595 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
8596 Meyering.
8597 * doc/autoconf.texi (Function Portability): Document the strnlen
8598 limitation.

8600 * lib/autoscan/functions: Adjust.
8602 2002-01-06 Akim Demaille <akim@epita.fr>
8604 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8605 package.m4, since is really depends upon configure.ac, not
8606 configure.
8607 * doc/autoconf.texi (testsuite Scripts): Adjust.
8608 * tests/Makefile.am (package.m4): New.
8609 EXTRA_DIST it since its a source.
8611 2002-01-06 Akim Demaille <akim@epita.fr>
8613 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8614 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8615 and PACKAGE_BUGREPORT from here...
8616 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8617 arguments.
8618 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8619 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8620 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8621 * tests/tools.at (autoheader): Adjust.
8622 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8624 2002-01-06 Akim Demaille <akim@epita.fr>
8626 * bin/autoscan.in (scan_file): Use `&used'.
8628 2002-01-03 Akim Demaille <akim@epita.fr>
8630 * doc/autoconf.texi (Output): Improved wording regarding use of
8631 AC_OUTPUT.
8632 From Olly Betts.
8634 2001-12-18 Kevin Ryde <user42@zip.com.au>
8636 * doc/autoconf.texi (Function Portability): Add notes on sscanf
8637 sometimes needing writable input.
8639 2001-12-17 Jim Meyering <meyering@lucent.com>
8641 * doc/autoconf.texi (New Macros): Tweak wording.
8643 2001-12-14 Akim Demaille <akim@epita.fr>
8645 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8646 trailing files, don't apply `-rf' to files which might not be
8647 created by configure (core, core.*, and *.core), but just `rm -f'.
8648 Suggested by Jonathan Kamens.
8650 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8652 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8654 2001-12-14 Akim Demaille <akim@epita.fr>
8656 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8658 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8660 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8661 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8662 abs_srcdir, top_srcpath to abs_top_srcdir.
8663 (_AC_OUTPUT_FILES): Adjust.
8664 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8665 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8666 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8668 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8670 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8671 C/Fortran linking on HP/UX, by extracting the Fortran library
8672 search path from the LPATH line in the $F77 -v output.
8674 2001-12-12 Kevin Ryde <user42@zip.com.au>
8676 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8677 forbidden file descriptors table.
8679 2001-11-26 Akim Demaille <akim@epita.fr>
8681 * bin/autoscan.in (%c_keywords): Build it at top level.
8682 Map to 1 in order to simplify its uses.
8684 2001-11-26 Akim Demaille <akim@epita.fr>
8686 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8687 Remove $filepath, useless.
8688 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8689 variables, they are really part of the tokens.
8690 Split the input line on spaces and then look for tokens.
8691 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8692 because of `lex$U.$(OBJEXT)'.
8693 (&scan_files): Use "@list" instead of join.
8694 * doc/Makefile.am (CLEANFILES): Add *.fns.
8696 2001-11-26 Akim Demaille <akim@epita.fr>
8698 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8699 Remove, replaced by...
8700 * tests/wrappl.in: Be common for all the Perl executables.
8701 In particular autoscan and autoheader want -I.
8702 * configure.ac: Adjust.
8703 * lib/autoscan/headers: errno.h is portable.
8705 2001-11-26 Akim Demaille <akim@epita.fr>
8707 * bin/autoscan.in (used): New.
8708 Use it.
8710 2001-11-26 Akim Demaille <akim@epita.fr>
8712 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8713 directives.
8714 (&scan_sh_file): Remove a duplicate pattern.
8715 (&check_configure_ac): Use long options.
8716 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8718 2001-11-26 Akim Demaille <akim@epita.fr>
8720 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8721 Before, having a line containing the opening of a multi line
8722 comment made the whole line be ignored.
8724 2001-11-26 Akim Demaille <akim@epita.fr>
8726 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8727 (testsuite Scripts): Be one of its subsection.
8728 (Autotest Logs): New.
8730 2001-11-26 Akim Demaille <akim@epita.fr>
8732 Test groups are now run two directories deeper.
8734 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8735 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8736 at_top_builddir.
8737 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8738 top_srcdir, builddir and top_builddir.
8739 Use `at_*dir' relatively to the directory containing the
8740 suite, use `*dir' when relatively to the current group dir.
8742 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8744 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8745 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8746 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8747 spelling errors.
8749 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8751 * doc/autoconf.texi (Using System Type): Add an example of `case
8752 $host' usage so people quit using `case $target' everywhere.
8754 2001-11-22 Akim Demaille <akim@epita.fr>
8756 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8757 spotted by Jim Meyering.
8759 2001-11-16 Paul Eggert <eggert@twinsun.com>
8761 This patch implements a `long double' suggestion by Oliver Kiddle.
8763 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8764 static, to catch errors if the value isn't known at compile-time
8765 and the compiler supports dynamic arrays. Change its name from
8766 `_array_' to `test_array' to avoid potential name clashes.
8767 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8768 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8769 better than double. Catch a bug in GCC 2.95.2 x86.
8770 * doc/autoconf.texi (C Compiler): Document the above.
8771 * NEWS: Likewise.
8773 2001-11-13 Akim Demaille <akim@epita.fr>
8775 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8776 hand.
8777 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8779 2001-11-13 Akim Demaille <akim@epita.fr>
8781 * lib/autotest/general.m4 (AT_INIT): After having run the test
8782 group, go back to the initial directory, not to at_suite_dir.
8784 2001-11-13 Akim Demaille <akim@epita.fr>
8786 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8787 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8788 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8789 option.
8790 (AT_CHECK_CONFIGURE): Use absolute paths.
8791 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8792 The problem is still the old one: there is no means in M4 (that I
8793 know about) to create a defining macro, because there is no means
8794 to create `$1' etc., therefore, the defining macro ``swallows''
8795 all the arguments meant to the defined macro.
8797 2001-11-13 Akim Demaille <akim@epita.fr>
8799 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8800 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8801 configure.ac.
8802 * tests/aclocal.m4: Remove, as it is no longer used.
8804 2001-11-13 Akim Demaille <akim@epita.fr>
8806 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8807 variable names when referring to a single test group, or to
8808 `suite' when referring to the whole test suite.
8809 `at_last_test' is removed: m4 compute at_format itself.
8810 (at_stdout, at_stder1, at_stderr): New variables.
8811 (AT_CHECK): Use them.
8813 2001-11-13 Akim Demaille <akim@epita.fr>
8815 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8816 in PATH.
8817 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8818 Do it as soon as a test fails, don't wait till the end of the test
8819 suite.
8820 Don't remove $as_me.[0-9]*, since these files no longer exist.
8822 2001-11-13 Akim Demaille <akim@epita.fr>
8824 * tests/tools.at: Use absolute paths, since we are no longer run
8825 in place.
8827 2001-11-13 Akim Demaille <akim@epita.fr>
8829 Now that tests are running in their own private dir, there is no
8830 need to list the files to remove at the end of tests groups.
8832 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8833 (AT_data_files, at_data_files): Remove.
8834 (AT_CLEANUP, AT_DATA): Simplify.
8835 (AT_INIT): Adjust.
8836 Remove the group dir if !debug && !failed.
8837 * tests/atspecific.m4: Adjust.
8839 2001-11-13 Akim Demaille <akim@epita.fr>
8841 Start a new layout for Autotest: `testsuite' creates
8842 `testsuite.dir' in which the at-check-line etc. files are to be
8843 found, and `testsuite.dir/003' where the test group 3 is run.
8845 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8846 at_check_line_file, at_format, at_test_normalized, at_group_dir
8847 are new variables.
8848 Create the directories.
8849 Use absolute paths for at- files.
8850 (AT_CHECK): Adjust.
8852 2001-11-11 Michael Matz <matz@kde.org>
8854 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8855 (m4_car2): New.
8856 (m4_car): Properly quote arguments.
8858 2001-11-13 Akim Demaille <akim@epita.fr>
8860 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8861 with stricter rules on LIBOBJS.
8863 2001-11-12 Paul Eggert <eggert@twinsun.com>
8865 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8866 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8867 __PROTOTYPES too.
8869 2001-11-12 Akim Demaille <akim@epita.fr>
8871 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8873 2001-11-12 Akim Demaille <akim@epita.fr>
8875 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8876 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8877 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8878 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8879 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8880 specify to what the macro should be defined (typically to 1).
8882 2001-11-12 Akim Demaille <akim@epita.fr>
8884 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8885 From Jim Meyering.
8887 2001-11-12 Akim Demaille <akim@epita.fr>
8889 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8890 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8891 definition used by Automake where LEX is +/- "${missing} lex" and
8892 `missing' itself contains variables.
8894 2001-11-12 Akim Demaille <akim@epita.fr>
8896 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8897 Now that M4sh pushes BODY, the comments were output at the end of
8898 the test suites.
8900 2001-11-08 Akim Demaille <akim@epita.fr>
8902 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8903 that we can trace macros from aclocal.m4.
8904 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8905 obsoleted, and redirect to the former anyway.
8906 Reported by Ralf Corsepius.
8908 2001-11-08 Akim Demaille <akim@epita.fr>
8910 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8911 processed only if present.
8912 * tests/torture.at (Configuring subdirectories): Use autoreconf
8913 instead of successive calls to autoconf.
8914 Add a nonexistent subdirectory to exercise the patch above.
8915 Reported by Ralf Corsepius.
8917 2001-11-08 Kevin Ryde <user42@zip.com.au>
8919 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8920 doesn't accept .S files.

8924 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8925 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8926 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8927 * bin/autom4te.in (warn_forbidden): New.
8928 (handle_output): Use it.
8929 Read m4_pattern_forbid with messages.
8931 2001-11-05 Akim Demaille <akim@epita.fr>
8933 * bin/autom4te.in (--normalize): Remove.
8934 * lib/autom4te.in: Adjust.
8936 2001-11-05 Akim Demaille <akim@epita.fr>
8938 * tests/Makefile.am (testsuite): Rename this target as...
8939 ($(TESTSUITE)): this.
8940 From Nicolas Joly.
8942 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8944 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8945 the --prefix option, also remove it's argument.
8947 2001-11-05 Akim Demaille <akim@epita.fr>
8949 * doc/autoconf.texi (testsuite Invocation): Update.
8950 (Writing testsuite.at): Update.
8952 2001-11-03 Akim Demaille <akim@epita.fr>
8954 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8956 2001-11-03 Akim Demaille <akim@epita.fr>
8958 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8959 (&file_name_is_absolute): New, wrappers around routines from
8960 File::Spec.
8961 Use and export them.
8962 (&find_configure_ac): Optionally take a directory where to look at.
8963 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8964 the arguments.
8965 Default @ARGV to `.', not find_configure_ac.
8966 (&autoreconf): Argument is a directory.
8967 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8968 * doc/autoconf.texi (autoreconf Invocation): Update.
8970 2001-11-03 Akim Demaille <akim@epita.fr>
8972 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8973 (@export_forward_subs): New.
8974 Add basename, dirname, and fileparse.
8975 (@EXPORT): Adjust.
8976 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8977 Don't look for aclocal flags if we already know aclocal is not
8978 used.
8979 Move aclocal.m4t only if it exists.
8980 Reported by Ezra Peisach.
8982 2001-11-03 Akim Demaille <akim@epita.fr>
8984 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8985 passed on command line, defaulting to ./configure.ac if present.
8986 (&maybe_autoreconf, File::Find): Remove, unused.
8987 (&autoreconf): If autoconf is not used, don't try to trace.
8989 2001-11-02 Akim Demaille <akim@epita.fr>
8991 * configure.ac: Bump to 2.52g.
8993 2001-11-02 Akim Demaille <akim@epita.fr>
8995 Version 2.52f.
8997 2001-11-02 Akim Demaille <akim@epita.fr>
8999 * config/config.guess, config/config.sub, doc/standards.texi:
9000 * config/lispdir.m4: Update from masters.
9001 * configure.ac: Bump to 2.52f.
9003 2001-11-02 Akim Demaille <akim@epita.fr>
9005 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9006 Don't run aclocal when aclocal.m4 is not from aclocal.
9007 From Ezra Peisach.
9008 Don't run libtoolize and gettextize if --install is not given.
9010 2001-11-01 Paul Eggert <eggert@twinsun.com>
9012 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9013 be invoked before _AS_LINENO_PREPARE.
9014 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9015 than character ranges.
9017 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9018 invoking AS_BASENAME. Set the locale variables to 'C' if
9019 possible, as POSIX requires this to get the traditional
9020 behavior.
9021 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9023 2001-10-31 Paul Eggert <eggert@twinsun.com>
9025 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9026 with {}, as that triggers a bug in Bash 2.05.
9028 (_AS_LINENO_PREPARE): Use Sed rather than
9029 Awk. Fix the sed prepass to work even if there are multiple
9030 instances of $LINENO on the same line. Do not substitute for
9031 other variables like $LINENOT. Do not check file dates; such a
9032 check is unreliable on sufficiently fast machines, and removing
9033 the check makes the code simpler and more reliable. Check for
9034 output and chmod failures.
9036 * doc/autoconf.texi (Special Shell Variables): Document
9037 the above.
9039 2001-10-31 Akim Demaille <akim@epita.fr>
9041 * tests/Makefile.am (atconfig): Remove this target, Automake
9042 handles it now.
9044 2001-10-31 Akim Demaille <akim@epita.fr>
9046 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9047 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9048 provided, while it is optional.
9049 * configure.ac: Adjust.
9051 2001-10-26 Paul Eggert <eggert@twinsun.com>
9053 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9054 lib/Autom4te/Struct.pm:
9055 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9056 with 5.005_02.
9058 * doc/autoconf.texi (Special Shell Variables): Document some
9059 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9061 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9062 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9063 eval $LINENO is not portable in practice.
9065 2001-10-24 Akim Demaille <akim@epita.fr>
9067 * lib/Autom4te/General.pm (backname): New.
9069 2001-10-24 Akim Demaille <akim@epita.fr>
9071 * m4/: Remove, merged into...
9072 * config/: here.
9074 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9076 * doc/autoconf.texi (Shellology): Mention the problems with bash
9077 2.05's use of ANSI quoting in its `set' builtin.
9079 2001-10-22 Paul Eggert <eggert@twinsun.com>
9081 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9082 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9083 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9084 POSIX decided to standardize on the int flavor of strerror_r.
9085 Always do char* test, as there's no reason not to.
9086 Assign to a char* var, to catch strerror_r that returns int*.
9088 * doc/autoconf.texi (Particular Functions):
9089 Document the above changes. Also, document the fact that
9090 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9092 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9094 2001-10-20 Akim Demaille <akim@epita.fr>
9096 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9097 the executable was missing from the log.
9099 2001-10-20 Akim Demaille <akim@epita.fr>
9101 * lib/Autom4te/General.pm (&update_file): If destination is
9102 unchanged, remove the source.
9103 (&up_to_date_p): Don't be verbose, be debug.
9104 * bin/autoreconf.in: No longer support --m4dir.
9105 (&autoreconf): Display the full path of the configure.ac we are
9106 studying.
9107 Trace it only once.
9108 Be sure to honor --force with gettextize.
9109 Always run aclocal.
9110 * doc/autoconf.texi: Adjust.
9112 2001-10-20 Akim Demaille <akim@epita.fr>
9114 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9115 Remove, dead.
9116 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9117 `intl' is already present, as it refuses unless --force.
9118 (&parse_args): Use -I, --include instead of the old Autoconf
9119 options.
9120 ($localdir, $autoconf_dir): Remove.
9121 (@include): New.
9122 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9124 2001-10-19 Jens Petersen <petersen@redhat.com>
9126 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9138 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9139 comment, explain how to install automatic mode selection.
9140 From Russ Allbery.
9142 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9144 * bin/autoreconf.in (autoreconf): Display the path to the
9145 configure.ac being studied.
9147 2001-10-18 Paul Eggert <eggert@twinsun.com>
9149 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9150 long, to work around a bug in the HP C compiler version HP92453-01
9151 B.11.11.23709.GP.
9153 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9154 (AS_BASENAME_EXPR): New macro.
9155 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9156 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9157 and fall back on 'sed' only if the other two fail. This makes
9158 AS_BASENAME act more like AS_DIRNAME.
9159 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9160 contains white space.
9161 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9162 Use AS_DIRNAME, since I think it's now DOS-friendly.
9163 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9164 Allow "dirname //FOO" to return either / or //, as POSIX allows
9165 either behavior.
9167 2001-10-10 Akim Demaille <akim@epita.fr>
9169 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9170 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9171 From Eric Sharkey.

9175 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9220 * bin/autoreconf.in: Rewrite in Perl.
9221 * configure.ac: Adjust.

9276 (autotest-mode): Adjust.
9277 * lib/emacs/autoconf-mode.el (autoconf-mode-map): Modernize, map

9290 include handle the m4_pattern_*, no longer push the

9303 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
9304 shell does not support LINENO, and if CONFIG_SHELL is unset or
9305 empty, and if we can find a shell that does support LINENO,
9306 then set CONFIG_SHELL to that shell and then re-execute
9307 ourselves with CONFIG_SHELL.
9309 2001-10-05 Paul Eggert <eggert@twinsun.com>
9311 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9312 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9313 build of $(TESTSUITE).
9315 2001-10-05 Akim Demaille <akim@epita.fr>
9317 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

9354 compatibility with POSIX shells.

9358 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
9359 instead of exec'ing to preserve $0 and $@.
9361 2001-10-01 Akim Demaille <akim@epita.fr>

9382 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
9383 Don't use nested parenthesization. This patch was originally
9384 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
9385 but somehow it didn't get incorporated then.
9386 * doc/autoconf.texi (Limitations of Usual Tools):
9387 Clarify remark about sed and nested parenthesization.
9389 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
9390 Report an error if the size cannot be determined even though
9391 the type exists.
9392 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9393 Check for `expr' arithmetic overflow, and for compilation failure,
9394 and invoke a new argument $4 if either is discovered.
9395 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9396 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9398 2001-09-28 Akim Demaille <akim@epita.fr>

9418 status when executing the ACTION-IF-FALSE.
9419 * tests/base.at (AC_TRY_*): Rename as...

9429 (AC_PROG_CPP requires AC_PROG_CC): here and...
9430 * tests/fortran.at (GNU Fortran 77): there.
9431 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9432 AC_TRY_RUN is about compilation, not shell commands.
9433 (Test Programs): AC_TRY_RUN works as used to be advertised.

9437 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9438 Raja R Harinath:
9439 Be sure to detect when $LINENO always returns the same value.
9440 Look for the original script, basename($0) is certainly not
9441 enough.
9442 Pass the CLI arguments to `$as_me.lineno'.
9444 2001-09-25 Akim Demaille <akim@epita.fr>
9446 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
9447 Be sure the close and reopen the LOG fd before and after using tee

9451 2001-09-23 Akim Demaille <akim@epita.fr>
9453 * bin/autom4te.in (parse_args): There can be several invocations
9454 of --language now.
9456 2001-09-23 Akim Demaille <akim@epita.fr>
9458 * doc/autoconf.texi (Top): Wrap in @ifnottex.
9460 2001-09-23 Akim Demaille <akim@epita.fr>
9462 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
9463 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.

9472 variables.
9474 * lib/autotest/general.m4: Do not reset AT_victims.
9475 Don't compute at_srcdir nor at_top_srcdir.
9477 * tests/tools.at: Hence use top_srcdir.
9479 * tests/Makefile.am, tests/autoconf, tests/autoheader,
9480 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:

9536 * lib/autoconf/autotest.m4: Create `package.m4'.
9537 * tests/Makefile.am (package.m4): Remove.
9539 2001-09-22 Akim Demaille <akim@epita.fr>

9544 `$LINENO' support replacement when not supported.
9545 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
9546 them explicitly to be sure they are not output before this section
9547 (via m4_require). Cosmetic only.

9549 * lib/autoconf/programs.m4: Replace all the occurrences of
9550 `__oline__' with `$LINENO'.
9551 * doc/autoconf.texi (Special Shell Variables): Document LINENO.

9556 character (u: -> ue) in a code comment.
9557 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
9558 it works.
9560 2001-09-21 Akim Demaille <akim@epita.fr>
9562 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9563 Suggested by Jim Meyering.
9565 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9567 * lib/autoconf/programs.m4: Use extensions listed in

9580 PATH_SEPARATOR.
9581 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9582 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9583 be used instead of ':'.
9584 * lib/autotest/general.m4: Replace occurrences of ':' in
9585 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9587 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9590 arguments. Fixed a typo.
9592 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9594 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9595 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9597 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9599 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

9606 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9608 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9609 already have $file). Set output files to binary mode (helps avoid
9610 CR issues on DOSish systems).
9612 2001-09-19 Akim Demaille <akim@epita.fr>
9614 * lib/autotest/general.m4: Englishoes.
9615 From Tim Van Holder and Alexey Mahotkin.
9617 2001-09-18 Paul Eggert <eggert@twinsun.com>
9619 * doc/autoconf.texi (Common Shell Constructs): New node,
9620 documenting AS_DIRNAME.
9621 (Limitations of Usual Tools): Refer to it when discussing dirname.
9622 Also, update discussion of POSIX standard to reflect latest draft.
9624 * lib/autoconf/c.m4:
9625 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9627 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9628 Do not pass a first argument with leading '-'
9629 to expr, by parenthesizing initial integers that might be negative.
9631 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9632 now merely checks whether it is an error to pass an argument
9633 to getpgrp.
9635 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9636 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9637 whether it is a (compile-time) error to pass an argument to
9638 getpgrp. This simpler test supports the revised documentation,
9639 and is all that AC_FUNC_GETPGRP's users really need.
9641 2001-09-18 Akim Demaille <akim@epita.fr>
9643 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9645 2001-09-18 Akim Demaille <akim@epita.fr>

9651 2001-09-18 Paul Wagland <paul@wagland.net>
9653 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9654 correctly.
9655 Add test for AS_BASENAME.
9656 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9657 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9658 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9659 * tests/base.at: Fixed the expected responses. The old ones were
9660 one line out...
9661 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9662 the documentation claims it should (and how it behaved in 2.13).
9664 2001-09-18 Akim Demaille <akim@epita.fr>
9666 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9667 the AC_CONFIG_COMMANDS invocation.
9668 This also solves the name clash problems.
9669 Don't set the package's ID.
9670 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9671 No longer to be shipped.
9672 (version.in): Remove.
9673 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9674 * lib/autoconf/status.m4: Adjust.
9675 Use `m4_PACKAGE_STRING'.
9676 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9677 the only optional argument is the name of the test suite.
9678 Expect `package.m4' to define the package signature.
9679 * lib/autom4te.in (Autotest): Add `package.m4?'.
9680 * tests/Makefile.am (package.m4): New.
9681 * tests/suite.at: ifnames is a victim.
9683 2001-09-18 Akim Demaille <akim@epita.fr>
9685 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9686 AC_LIBSOURCE, AC_CONFIG_FILES.
9687 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9688 program version string doesn't match the package's.
9689 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9690 after `(cached)'.
9692 2001-09-17 Paul Eggert <eggert@twinsun.com>
9694 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9695 Allow expression to return any value that can fit into unsigned long
9696 (not int, as before). Check for output errors.
9698 2001-09-17 Bruno Haible <haible@ilog.fr>
9700 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9701 Always include <stdio.h> and <stdlib.h>. Evaluate
9702 the expression in an extra function before these includes. Call
9703 fprintf "%d" only after ensuring the argument is of type 'int'.
9704 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9706 2001-09-17 Paul Eggert <eggert@twinsun.com>
9708 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9709 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9710 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9711 when they don't exist.
9713 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9714 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9715 need it.
9717 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9718 version with the version used by fileutils 4.1, except use
9719 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9720 we don't need it.
9722 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9724 2001-09-13 Akim Demaille <akim@epita.fr>
9726 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
9727 _first_.
9728 Reported by Gerrit P. Haase.
9730 2001-09-13 Akim Demaille <akim@epita.fr>
9732 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9748 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
9749 Likewise.
9750 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
9751 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.

9753 AT_tests_all for consistency.
9754 Set at_victims.
9755 (AT_VICTIMS): Similar to AT_KEYWORDS.
9756 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
9758 2001-09-13 Akim Demaille <akim@epita.fr>
9760 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9762 2001-09-13 Akim Demaille <akim@epita.fr>
9764 * lib/autotest/general.m4 (AT_INIT): Create and remove
9765 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9766 test suites can cohabit.
9768 2001-09-13 Akim Demaille <akim@epita.fr>
9770 * tests/mktests.sh: Don't output banners for empty test files.
9772 2001-09-13 Akim Demaille <akim@epita.fr>
9774 Test suites can be run independently of configure.
9776 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.

9792 * tests/ifnames: New.
9794 2001-09-13 Akim Demaille <akim@epita.fr>
9796 * lib/autotest/general.m4 (AT_INIT): Let --keywords also match
9797 test group titles.

9820 2001-09-10 Akim Demaille <akim@epita.fr>
9822 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
9823 PATH_SEPARATOR, let M4sh compute it.
9824 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
9825 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

9827 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Here.
9828 Simplify when the path is not a literal.
9829 (AS_UNAME): Use it to report PATH.

9831 (_AC_INIT_DEFAULTS): AC_SUBST PATH_SEPARATOR.
9832 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Use _AS_PATH_WALK.
9833 * lib/autotest/general.m4 (AT_INIT): Use _AS_PATH_WALK to
9834 normalize the path, and to look for victims.
9835 * tests/semantics.at (AC_PATH_PROG & AC_PATH_PROGS)
9836 (AC_CHECK_PROG & AC_CHECK_PROGS): Use PATH_SEPARATOR.
9838 2001-09-07 Akim Demaille <akim@epita.fr>
9840 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
9841 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
9842 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
9843 related variables into `at_package_*'.
9844 * lib/autotest/general.m4 (AT_VICTIMS): New.
9845 (AT_INIT): Adjust for stand-alone/embedded test suites.
9846 (AS_MESSAGE_LOG_FD): Define and use it.

9851 2001-09-07 Akim Demaille <akim@epita.fr>
9853 Move toward possibly stand-alone test suites.
9855 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
9856 in addition, it introduces useless differences in logs.
9857 (AT_INIT): Let atconfig and atlocal be both optional.
9858 Adjust PATH computation.
9859 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

9863 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon

9869 to avoid GCC warnings.
9870 From Uwe Seimet.
9872 2001-09-05 Akim Demaille <akim@epita.fr>
9874 * bin/autom4te.in: --language is -l, not -s.
9876 2001-09-05 Akim Demaille <akim@epita.fr>
9878 Be ready to handle filenames as stupid as `dnl.at', for if even
9879 the maintainer is dumb enough to do that...
9881 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9882 excellence in M4 quotation: consider `__file__' is active.
9884 And BTW, when invoking m4, pass the --include in the right order:
9885 the wrong one.
9887 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
9888 4m.
9890 2001-09-05 Akim Demaille <akim@epita.fr>
9892 * lib/Autom4te/XFile.pm: New lib file.
9893 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
9894 * bin/autoheader.in: Use it.
9896 2001-09-05 Akim Demaille <akim@epita.fr>
9898 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
9899 defined.

9904 * bin/autoheader.in, bin/autoupdate.in (&parse_args): Adjust.
9906 * bin/autoscan.in: Use `getopt' and `find_files' etc.
9907 Add -I, --include support.
9908 * doc/autoconf.texi (autoscan Invocation): Adjust.
9910 2001-09-05 Akim Demaille <akim@epita.fr>
9912 CVS GNU M4 doesn't like `undefine(undefined)'.
9914 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
9915 New, extracted from main.
9916 Use IO::File wherever possible.
9917 (input.m4): Be constant, use -I instead of hard coding $tmp.
9918 Therefore be a quoted heredoc.
9919 Don't invoke `_au_disable', since ac was not loaded, but just
9920 `unm4.m4'.
9922 2001-08-31 Akim Demaille <akim@epita.fr>
9924 Version 2.52d.
9926 2001-08-31 Akim Demaille <akim@epita.fr>
9928 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
9929 previous patch.

9932 2001-08-31 Akim Demaille <akim@epita.fr>
9934 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
9935 serious problems handling heredocs in heredocs.
9936 Reported by Nicolas Joly.
9938 2001-08-31 Akim Demaille <akim@epita.fr>
9940 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
9941 (Making testsuite Scripts): Update.
9943 2001-08-31 Akim Demaille <akim@epita.fr>
9945 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
9947 2001-08-31 Akim Demaille <akim@epita.fr>
9949 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9950 (testsuite Scripts): There is no such thing as `atconfig.in'.
9951 And actually one diagram is missing: test suite runtime.
9953 2001-08-31 Akim Demaille <akim@epita.fr>
9955 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9956 inverse order.
9958 2001-08-31 Akim Demaille <akim@epita.fr>
9960 * bin/autoupdate.in (@include): `installcheck' revealed the path
9961 to m4sugar was lacking!
9963 2001-08-31 Akim Demaille <akim@epita.fr>
9965 * man/Makefile.am (.x.1): We really have to pass
9966 autom4te_perllibdir.
9968 2001-08-31 Akim Demaille <akim@epita.fr>
9970 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9971 debug scripts, in particular passing explicitly listed tests to
9972 run is stupid.
9974 2001-08-31 Akim Demaille <akim@epita.fr>
9976 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9977 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9978 Use directly autom4te, not autoconf.
9979 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
9981 2001-08-31 Akim Demaille <akim@epita.fr>
9983 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
9984 * bin/autoheader.in (%symbol): Strip arguments of macros.

9992 * bin/autom4te.in (&parse_args): Die on unknown languages.
9993 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
9994 need for autoconf.
9995 Promote --include over --macrodir and other obsolete options.
9997 2001-08-31 Akim Demaille <akim@epita.fr>
9999 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

10001 * bin/autom4te.in ($autoconf): Pass --force.
10002 `print $out' doesn't print `$_' but `$out'.
10003 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10004 (autoheader): Pass --force since the test suite goes too fast for
10005 the time stamps.
10006 Adjust to the new autoheader messages.
10008 2001-08-31 Akim Demaille <akim@epita.fr>
10010 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
10011 Check the completeness of the #template.
10012 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
10013 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
10014 invocation.

10018 * lib/Autom4te/General.pm (&find_file, &update_file): New.
10019 * bin/autoupdate.in, bin/autoheader.in: Adjust.
10020 Drop AC_MACRODIR dead for real.
10021 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10022 `autoheader: `config.hin' is created'.
10023 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10025 2001-08-31 Akim Demaille <akim@epita.fr>
10027 * bin/autoheader.in: Rewrite in Perl.
10028 * tests/autoheader: Adjust.
10030 2001-08-31 Akim Demaille <akim@epita.fr>
10032 * bin/autoconf.in (--include, -I): New option.
10033 Map --localdir, --autoconf-dir onto it.
10034 Forward autom4te's options instead of interpreting them.
10035 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10036 There is no such envvar since the inception of autom4te.cfg.
10037 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10038 * bin/autoupdate.in: Adjust, and perform more control.
10039 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
10040 * tests/autoconf: Dittowise.
10042 2001-08-31 Akim Demaille <akim@epita.fr>
10044 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10045 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10046 optionally `FILE'.
10047 Use -e, not -f, since /dev/null for instance is OK.
10048 (&parse_args): Adjust.
10049 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10051 2001-08-31 Akim Demaille <akim@epita.fr>
10053 * configure.ac: Also find tested executables in bin.
10054 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10055 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10056 installed peer executables, only PATH is allowed to resolve it.
10057 Pass `autoconf_dir' via options, not via invisible envvars.
10058 * lib/Autom4te/General.pm (&find_peer): Remove.
10059 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10060 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10061 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10062 find the executables for it.
10063 * tests/Makefile.am: Major cleanup. Too lazy to document...
10064 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10065 We only need PERL.
10066 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10067 indeed related to running the test suite, while passing
10068 --autoconf-dir and others is related to running non installed
10069 Autoconf executables. So don't do that, leave it to...
10070 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10071 * tests/autoscan: New.
10072 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10073 refer to library files: rely on --language.
10075 2001-08-29 Akim Demaille <akim@epita.fr>
10077 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
10078 s/--set/--language/.
10080 2001-08-29 Akim Demaille <akim@epita.fr>
10082 * doc/autoconf.texi: Strip the @nodes.
10083 Suggested by Paul Eggert.
10084 (Initializing configure): Typo.
10086 2001-08-29 Akim Demaille <akim@epita.fr>
10088 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10089 Suggested by Paul Eggert.
10091 2001-08-29 Akim Demaille <akim@epita.fr>
10093 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10094 download in a tmp dir.
10096 2001-08-29 Akim Demaille <akim@epita.fr>
10098 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10099 case insensitive OSes out there :(
10100 From Tim Van Holder.
10102 2001-08-29 Akim Demaille <akim@epita.fr>
10104 * lib/autom4te.in: New.
10105 * lib/Makefile.am (edit, autom4te.cfg): New.
10106 * bin/autom4te.in (BEGIN): Simplify.
10107 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
10108 (&load_configuration): New. Use it.
10109 (&parse_args): Support --mode, --set, and --melt.
10110 * bin/autoconf.in: Simplify and adjust.
10111 * tests/Makefile.am (AUTOMAKE): Use --set.
10112 * tests/atlocal.in: Adjust.
10113 * BUGS: distcheck and check are weak.
10115 2001-08-29 Akim Demaille <akim@epita.fr>
10117 * lib/autotest/general.m4: Use
10118 foo=`(command) 2>/dev/null`
10119 not
10120 foo=`command` 2>/dev/null
10121 (at-devnull): Rename as...
10122 (AT-devnull): this.
10123 (--clean): Remove AT-* files too.
10124 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10125 Reported by Nicolas Joly.
10127 2001-08-28 Akim Demaille <akim@epita.fr>
10129 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

10135 * doc/autoconf.texi (Function Portability): Mention C right shifts.
10137 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
10139 * lib/autotest/general.m4: Reword some messages.
10140 (AT_INIT): Check for the `times' builtin before using it.
10141 Support test ranges as arguments to the testsuite.
10142 Have -e imply -d as the help text suggested.
10144 2001-08-27 Akim Demaille <akim@epita.fr>
10146 * Makefile.maint: Formatting changes.
10147 (do-po-update, po-update, cvs-update, update): New targets.

10152 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

10159 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10160 Support `VAR=VAL' as arguments.
10161 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
10162 may be set via the command line.
10164 2001-08-27 Akim Demaille <akim@epita.fr>
10166 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
10167 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
10168 first the build dirs, then the src dirs.

10180 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
10181 `ac_top_builddir' to mimic Automake's vocabulary, which much more
10182 readable.
10183 Adjust callers.
10184 * doc/autoconf.texi (Configuration Actions): Document the vars
10185 available in commands.
10186 Emphasize the risks of collisions in init-cmds.

10190 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
10191 (Initializing configure): this new node.
10193 2001-08-27 Akim Demaille <akim@epita.fr>

10206 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
10207 to...
10208 * lib/autoconf/autoheader.m4: this new file.

10214 2001-08-27 Akim Demaille <akim@epita.fr>
10216 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
10217 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
10218 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
10219 -> ac_dir).
10220 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
10221 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
10223 2001-08-27 Akim Demaille <akim@epita.fr>
10225 * lib/autoconf/autoconf.m4 (AC_CONFIG_COMMANDS)

10248 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
10249 (AMTAR): Help automake define it.
10250 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
10251 needed, 1.5 can have a macro and a target with the same name.
10252 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
10253 * m4/strip.m4: New.

10266 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.

10268 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10269 the name of the directory they're in, instead of the filename,
10270 since version.m4 is now in m4sugar, but m4_acversion must not be
10271 classified as an Autoconf macro.
10272 ($input_m4): Don't qualify the path to m4sugar.
10273 Rather, pass autoconf_dir to m4.
10274 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
10275 * tests/suite.at: Require 2.52c.

10362 2001-08-20 Akim Demaille <akim@epita.fr>
10364 Info readers seem to need `Index' in the index node title :(
10366 * doc/autoconf.texi: Reverse the 2001-08-15 change which
10367 simplified index node names.

10411 2001-08-20 Akim Demaille <akim@epita.fr>
10413 Huh!?!?! There are still some user EOF tags used, which prevents

10416 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
10417 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

10480 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
10481 `$0.log' as for projects where testsuite is in src, we'd have

10496 2001-08-17 Akim Demaille <akim@epita.fr>
10498 * doc/autoconf.texi: Work around Texinfo buglets.
10499 (Transformation Rules): One example is enough, users are expected
10500 to have their brains on. And BTW, use DESTDIR.
10501 (dvar): New macro. Use it.
10503 2001-08-17 Akim Demaille <akim@epita.fr>
10505 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

10553 (cvs-dist): depends upon it.
10555 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
10557 * tests/Makefile.am: Use a clean-local rule to remove
10558 autom4te.cache (it's a directory, not a file.
10559 * Makefile.am: Ditto (but maintainer-clean-local).
10561 2001-08-15 Akim Demaille <akim@epita.fr>
10563 * bin/autom4te.in (@m4_warning): New.
10564 (&handle_m4): Use it.
10565 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10566 warnings are issued at each run.
10567 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10568 is in the src tree.
10570 2001-08-15 Akim Demaille <akim@epita.fr>

10573 don't waste time running `autoupdate --version' works.
10574 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10576 2001-08-13 Akim Demaille <akim@epita.fr>
10578 * doc/autoconf.texi (ma): Rename this index as...

10629 * tests/mktests.sh: Update year in copyright notice.
10631 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
10633 * tests/semantics.at (AC_C_BIGENDIAN): New test.
10635 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10637 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10638 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10639 * doc/autoconf.texi (C Compiler Characteristics): Update
10640 documentation for AC_C_BIGENDIAN.
10642 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10644 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10645 magic values from an object file when cross-compiling.
10646 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10648 2001-08-10 Akim Demaille <akim@epita.fr>
10650 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10651 effects.
10652 Suggested by Russ Allbery.
10654 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10656 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10657 current $prefix to the sub-configures.
10659 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10661 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10662 extension (needed on BeOS). Reported by Guido van Rossum.
10664 2001-08-09 Akim Demaille <akim@epita.fr>
10666 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10668 2001-08-07 Akim Demaille <akim@epita.fr>
10670 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10671 removed.
10672 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10673 No need to remove the files before and after the each test, before
10674 each test and at the end of the suite is enough.
10675 Display only the children `times', not the shell's.
10676 If the test failed or was skipped, at-times is not available.
10678 2001-08-07 Akim Demaille <akim@epita.fr>
10680 Always produce testsuite.log, including when there are no
10681 failures. This helps getting information on skipped tests, and
10682 duration of the tests. Err, implement the latter btw.
10684 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10685 Dump information on the first run of each test.
10686 (AT_CLEANUP): Create `at-times' containing the duration of the
10687 test group.
10689 2001-08-07 Akim Demaille <akim@epita.fr>
10691 The use of `dumpstat' revealed that `len' was used although it
10692 should not. m4_text_wrap was using it, but in the Autoconf world
10693 where it is legal. Hence (i) test M4sh in its own world, not
10694 Autoconf's, and (ii), ahem, fix the bug :)
10696 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10697 does not like `' instead of [].
10698 (AT_INIT): Forbid `^_?AT_'.
10699 And don't output such tokens.
10700 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10701 `script.as', and `autom4te.cache'.
10702 Remove `empty' and `macro' which are no longer used.
10703 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10704 * tests/m4sugar.at: Use it.
10705 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10707 2001-08-07 Akim Demaille <akim@epita.fr>
10709 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10711 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10713 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10715 2001-08-04 Akim Demaille <akim@epita.fr>
10717 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10718 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10719 AC_TRY_LINK.
10720 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10721 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10722 (AC_F77_MAIN): Likewise.
10724 2001-08-04 Akim Demaille <akim@epita.fr>
10726 Don't rely on M4sugar outputting the patterns in files, since we
10727 might process the output _without_ running m4, hence without these
10728 files.

11295 cross-language link tests can be performed successfully.
