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

42 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
43 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
44 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
45 this.
47 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
49 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
50 problems with arg script text that doesn't end in newline, and
51 with '-e a...'. Problems reported by Ralf Wildenhues.
53 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
55 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

61 to last change.
63 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
65 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
66 --help' should mention that `--version' outputs configuration
67 settings. Report by Bruno Haible.
69 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
71 Fix test suite failures reported by Pierre in
72 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
73 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
74 the compiler created a file "b.out" when it didn't create anything
75 at all.
76 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
77 Discard stderr too, when invoking the test script.
79 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)

90 leading white space from text. From Bruno Haible.
92 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
94 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
95 compiler complains about it, even if things works after the
96 complaint. Problem reported by Peter O'Gorman.
98 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
99 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
100 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
102 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
104 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
105 after -R regardless of host. Patrick Welche reports that this
106 fixes things on NetBSD 3.99.
108 * NEWS: Recommend M4 1.4.5.
109 * README: Likewise.
110 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
111 * tests/tools.at (autom4te cache): Update wording of diagnostic
112 to match M4 1.4.5.
114 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
116 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
117 under AC_C_VOLATILE.
118 (Volatile Objects): Be a little less skeptical about what
119 "volatile" means. Derived from thoughts by Ben Pfaff in
120 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
122 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
124 * doc/autoconf.texi: Fix some typos.
126 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
128 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
129 more globally, since the 2006-06-30 patch didn't suffice. Problem
130 reported by Keith Marshall. Also, don't bother with builddir2,
131 since it shouldn't be needed any more.
133 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
135 * doc/autoconf.texi (Generic compiler characteristics):
136 Document AC_COMPUTE_INT. Fix wrong statements on Default
137 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
139 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
140 (_AC_COMPUTE_INT): Add obsoletion warnings.
141 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
142 AC_COMPUTE_INT.
144 * NEWS: Document change.
146 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
148 * doc/autoconf.texi (Volatile Objects): New section.
150 * NEWS: Document previous change.
152 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
154 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
155 Require that long long int be at least 64 bits wide. C99 requires
156 this and enough programs depend on it so we should check for it.
157 Bruno Haible reports in
158 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
159 that long long int is 32 bits wide with some nonstandard compilers.
160 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
162 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
164 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
165 to a nonexistent file, so that we don't have to worry about
166 a local site configuration that doesn't use /usr/local.
167 Problem reported by Keith Marshall in
168 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
170 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
172 * doc/autoconf.texi: Be more consistent about using @acronym with
173 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
174 quite right (it talked about "OSF/Tru64", even though the
175 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
176 and it even mentioned "OSF 4"!) and at this point there's little
177 reason to talk about OSF any more, since it died in 1994.
178 (Specific Compiler Characteristics): Simplify example of
179 negative-size array.
180 (File Descriptors): Reorder to make the text flow better.
181 Remove joke about "appreciate the various levels"; I didn't get it.
182 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
183 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
184 (File Descriptors, Limitations of Usual Tools):
185 Tone down the advice against renaming or removing open files.
186 (Limitations of Usual Tools): Add a new section, on 'rm'.
188 2006-06-26 Stepan Kasal <kasal@ucw.cz>
190 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
191 -lXt in LIBS, idea from Karsten Hopp; this was due since
192 this change:
194 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
195 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
196 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
197 (which belong to Xt, not X itself). See Debian bug 327655.
199 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
201 * configure.ac (AC_INIT): Bump to 2.60a.
202 * NEWS: Update.
204 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
206 Version 2.60.
208 * configure.ac, NEWS: Update.
210 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
212 * config/texinfo.tex: Sync from upstream.
214 * bin/autom4te.in (handle_traces): Transform the `@S|@'
215 quadrigraph correctly in traces.
217 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
218 Fix typos.
220 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
221 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
222 not defined.
223 * doc/autoconf.texi (Changed Directory Variables): New node,
224 to document the whole `datarootdir' business a bit better.
225 * NEWS: Update.
226 * tests/torture.at (datarootdir workaround): Extend test.
227 Prompted by report by Alexandre Julliard.
229 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
231 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
232 when using default mode of IBM C 6 for AIX. Problem and two-line
233 fix reported by Larry Jones.
235 2006-06-22 Alexandre Julliard <julliard@winehq.org>
237 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
238 about literal '${datarootdir}' if a definition is found in the
239 output file.
241 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
243 * NEWS: Use "M4" rather than "m4" when appropriate.
244 Problem reported by Eric Blake.
245 * doc/autoconf.texi: Likewise.
246 Use @acronym around BSD, GCC, and GNU when appropriate.
247 (Why GNU M4): Renamed from "Why GNU m4".
248 (Redefined M4 Macros): Mention that Posix
249 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
250 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
251 to int.
253 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
255 * bin/autom4te.in (handle_output): Do not forbid the empty
256 pattern.
257 * tests/tools.at (autoconf: the empty token): New test.
259 2006-06-20 Stepan Kasal <kasal@ucw.cz>
261 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
262 calls, so that we do not care whether they are LIFO or FIFO;
263 in the m4_wrap, do not check which diversion is the topmost
264 one, just check that the stack is balanced at the end.
265 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
266 base diversion forever--pop the previous diversion before
267 opening the new one; consequently, remove the m4_wrap call.
268 * lib/autotest/general.m4 (AT_INIT): Likewise.
269 * tests/m4sugar.at: Do not use
270 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
272 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
273 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
275 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
276 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
277 Rework example of m4wrap token-pasting trouble so that it doesn't
278 care whether it's LIFO or FIFO.
279 Fix some "contrary to"s that are awkward in English.
281 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
283 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
284 to `yes' instead of `int$1_t' if the type is found, for more
285 consistent configure output (where $1 is the number of bits).
286 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
287 Suggested by Bruno Haible.
289 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
290 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
291 with system headers. Report by Bruno Haible.
293 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
295 * config/config.guess, config/config.sub: Sync from upstream.
297 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
298 in order to avoid picking up an older installed frozen m4sh.m4f.
299 Besides an outdated shell startup, this could have been created
300 by an earlier M4 version with incompatible frozen file format.
302 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
304 * README: Recommend m4 1.4.4 instead of 1.4.3..
305 * doc/autoconf.texi: Likewise.
306 (Special Chars in Names): Say that $(.FOO) is portable, as
307 suggested by Stepan Kasal.
308 (Installation Directory Variables, Build Directories):
309 (Automatic Remaking, Subdirectories, Fortran Compiler):
310 (Making testsuite Scripts, Defining Directories):
311 Quote variable usages better.
312 (Making testsuite Scripts): Add clean-local rule to makefile
313 snippet, by Eric Blake.
314 (Installation Directory Variables): Fix table item font.
315 Reword slightly to clarify. Generalize advice about
316 not using special characters to include all file-related
317 vars, not just VPATH.
318 (Special Chars in Variables): Warn about special characters in
319 $(srcdir) too.
320 (Assignments): Clarify default-value example as suggested by
321 Ralf Wildenhues in
322 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
323 (Special Shell Variables): Note leading ./ or ../, as suggested
324 by Eric Blake.
325 (Limitations of Builtins): Under cd, warn about CDPATH.
326 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
327 Ralf Wildenhues.
329 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
331 * doc/autoconf.texi (Configuration Actions): Remove duplicate
332 `@var', for texi2html.
333 (Systemology): Some more word wrapping, for DVI output.
334 (autom4te Invocation): The short option for `--melt' is `-M',
335 not `-m'.
337 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
339 * doc/autoconf.texi: More formatting and English tweaks,
340 many suggested by Ralf Wildenhues.
341 Reword to avoid "@code{...}'s" and the like, since it's ugly
342 with Emacs info mode. discontents -> woes.
343 Put a few "will"s back. time stamp -> timestamp.
344 side-effect -> side effect.
346 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
348 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
349 Warn about $@ not persisting. Problem reported by Julien Danjou in
350 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
351 (Special Chars in Names): Renamed from Leading _ in Macro Names.
352 Mention other special chars, too.
354 2006-06-14 Eric Blake <ebb9@byu.net>
356 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
358 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
360 * doc/autoconf.texi: Some systematic minor improvements, as
361 follows. Use "makefile" when talking about makefiles
362 generally (which might be named "makefile" or "Makefile" or even
363 "foo.mk"), "Makefile" when talking about a specific makefile
364 called "Makefile". This unclutters the text from weird quotes
365 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
366 values" rather than "@var{foo}s" and similar constructs containing
367 "}s". Use "Make rules" rather than "Makefile rules". Minor
368 English-language improvements. Change the prefix "sub-" to "sub"
369 and "re-" to "re".
370 Put blank lines around examples more consistently.
371 Avoid "rather" and "very" as intensifiers.
372 Avoid "will" as an auxiliary.
373 (Limitations of Make): Split this node into....
374 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
375 (Leading _ in Macro Names, Backslash-Newline-Newline):
376 (Backslash-Newline Comments, Long Lines in Makefiles):
377 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
378 (obj/ and Make, make -k Status, VPATH and Make):
379 (VPATH and Double-colon, $< in Explicit Rules):
380 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
381 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
382 New nodes, resulting from splitup of Limitations of Make.
383 All cross-references changed. Raise the top node from
384 a section to a chapter, and all subnodes accordingly.
385 Redo the introductory wording to match the new organization.
386 (Installation Directory Variables): Use an example that is
387 closer to what Autoconf actually does. Mention that VPATH's
388 value should not contain metacharacters or white space.
389 (Fortran Compiler): Fix a VPATH bug in an example.
390 (Leading _ in Macro Names): Mention that this problem is no longer
391 of practical concern.
392 (VPATH and Make): Reword the advice to make it clearer
393 that Autoconf and Automake support VPATH in non-GNU make, but
394 many packages have bugs in this area.
395 ($< in Explicit Rules): Refer to Build Directories rather
396 than using a (non-VPATH-safe) example.
397 (Automatic Rule Rewriting): Mention the sort of disaster that
398 can ensue with Solaris-style rule rewriting with VPATH.
400 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
402 * doc/install.texi (Compilers and Options): Weaken the
403 suggestion to use GNU make for VPATH builds.
405 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
406 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
408 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
409 in regular expression.
411 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
413 * doc/autoconf.texi (Installation Directory Variables):
414 Drop extra @samp from `@table @samp' item.
415 (Limitations of Usual Tools): Comment fix.
416 Do not nest @samp just to point to other table items.
417 (Writing testsuite.at) <AT_CHECK>: The second argument to
418 `@dvar' is already @samp'ed.
419 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
420 do not use @var in the second argument.
422 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
424 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
425 $as_shell.exe too. Problem reported by Andreas Buening in
426 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
428 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
430 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
431 `unused variable' compiler warning, for `-Wall -Werror'.
432 Reported by Jaap Haitsma in
433 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
435 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
437 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
438 case the compiler dumps core. Problem reported for
439 OpenServer 5.0.7 by Tim Rice in
440 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
441 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
442 Likewise.
444 2006-06-06 Tim Rice <tim@multitalents.net>.
446 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
447 "ERROR" only shows up in "make check" output if there is an
448 error.
450 2006-06-06 Eric Blake <ebb9@byu.net>
452 * tests/tools.at (automatically allowed tokens): Fix typo.
454 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
456 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
458 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
459 typically overflows on x86 CPUs, even though the C standard
460 requires otherwise.
462 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
464 * configure.ac (AC_INIT): Bump to 2.59e.
465 * NEWS: Update.
467 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
469 Version 2.59d.
471 * config/texinfo.tex: Sync from upstream.
473 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
474 seen, invoke libtoolize with `--ltdl' argument.
475 * lib/autom4te.in (Autoreconf-preselections): Adjust.
476 * NEWS: Update.
477 Suggested by Eric Blake.
479 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
481 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
482 reported by Ralf Wildenhues.
483 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
485 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
487 * THANKS: Update.
489 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
491 * doc/autoconf.texi: Modernize some of the references to Solaris.
493 2006-06-05 Stepan Kasal <kasal@ucw.cz>
495 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
496 message issued by AC_REQUIRE.
497 * tests/m4sugar.at: Check m4_require's error message.
498 * tests/base.at: Check AC_REQUIRE's error message.
499 * tests/local.at (AT_CHECK_M4): New macro, almost identical
500 to...
501 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
502 AT_CHECK_M4.
503 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
504 `expout' as the last parameter.
505 * tests/tools.at: Adapt to the above change.
507 2006-06-04 Stepan Kasal <kasal@ucw.cz>
509 * doc/autoconf.texi (Limitations of Usual Tools): Correct
510 information about race-free implementations of mkdir.
512 2006-06-04 Eric Blake <ebb9@byu.net>
514 * bin/autoreconf.in (help): Document M4 environment variable.
515 * bin/autoconf.as (Usage): Likewise.
516 * bin/autom4te.in (help): Likewise.
517 * doc/autoconf.texi (autom4te Invocation): Likewise.
519 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
521 * NEWS: GNU make now recommended for VPATH builds.
522 Mention that some macros are now documented to be obsolescent.
523 * doc/autoconf.texi:
524 Prefer "current" to "modern" to describe
525 currently-used (albeit perhaps old-fashioned) hosts.
526 Mention which ancient features no longer need to be worried about.
527 setgid -> set-group-ID
528 setuid -> set-user-ID (these are the Posix terms)
529 Fix some misuses of "only".
530 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
531 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
532 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
533 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
534 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
535 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
536 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
537 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
538 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
539 Mention that these macros are obsolescent.
540 (Installation Directory Variables): shall -> should
541 (File Descriptors): Mention that 0, 1, 2 might get reopened.
542 Mention that it's now safe to use 3 and 4.
543 (Limitations of Usual Tools): cp -r is now specified by Posix.
544 Omit longwinded and obsolescent discussion of cp -f.
545 Modernize discussion of expr, ls.
546 (Limitations of Make): Modernize discussion of VPATH builds.
547 Mention $? as a workaround in some cases.
548 * doc/install.texi (Basic Installation):
549 Mention "./configure; make; make install" first. Be more
550 specific about why this file is generic. Remove unnecessary
551 parens. Remove misleading "only". Remove obsolete advice
552 about csh. Don't say "configure" takes awhile; say it
553 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
554 and CC=c99 rather than CC=c89, as these are blessed by current
555 Posix. Recommend GNU make if doing a VPATH build.
557 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
559 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
560 examples involving shell prompts.
562 2006-06-02 Stepan Kasal <kasal@ucw.cz>
563 and Paul Eggert <eggert@cs.ucla.edu>
565 * doc/autoconf.texi (Here-Documents): Add details about the
566 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
567 use "here-documents" instead of "here documents".
569 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
571 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
573 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
575 * doc/autoconf.texi (File System Conventions): Warn about ":"
576 anywhere in directory names.
578 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
580 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
581 about quoting the case statement, just in case.
582 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
583 was fixed in ksh93g; reported by Ralf Wildenhues.
585 2006-05-31 Stepan Kasal <kasal@ucw.cz>
587 * doc/autoconf.texi (System Services): Do not document
588 overriding EXEEXT via ac_cv_exeext=ext.
589 (Particular Programs) <AC_PROG_MKDIR_P>:
590 Document that ${MKDIR_P} understands --.
591 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
592 comment.
594 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
596 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
597 argument with leading hyphen. Problem reported by Paul Eggert.
599 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
601 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
602 about quoting ac_try: quote all of it, if any of it seems suspicious.
603 This means we don't have to worry about ${ or sed any more.
604 Also, double-quote the case statement, to work around misuses via
605 underquoting as reported by Ralf Wildenhues in
606 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
607 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
608 undocumented and dangerous macro.
609 Problem reported by Ralf Wildenhues in
610 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
612 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
614 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
615 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
616 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
618 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
620 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
621 since evidently some packages rely on the old, broken behavior.
622 Problem reported by Ralf Wildenhues in
623 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
624 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
625 pre-2006-05-26 definitions, but leave in the comments that
626 these macros are dangerous and should not be used.
627 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
628 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
629 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
630 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
631 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
633 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
635 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
636 the use of 'tr', since this is our only use of 'tr'.
638 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
639 and Paul Eggert <eggert@cs.ucla.edu>
641 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
642 Don't assume 'grep' works on long lines, since AIX grep doesn't.
644 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
646 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
647 the output file in the `${datarootdir}' test.
649 2005-05-28 Stepan Kasal <kasal@ucw.cz>
650 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
652 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
653 mention of `datarootdir' in the input file(s), but literal
654 `${datarootdir}' in the output file, and we haven't warned yet,
655 then warn as well: the user may have (erroneously) used
656 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
657 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
658 * tests/torture.at (datarootdir workaround): Extend this test.
659 * NEWS: Update.
661 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
662 and Paul Eggert <eggert@cs.ucla.edu>
664 * doc/autoconf.texi (autoheader Invocation): The first argument to
665 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
666 alternatives and clear up the language a bit.
668 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
670 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
671 ac_config_guess, ac_config_sub, ac_configure.
672 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
673 Fix typo that prevented an unnecessary space from being removed.
674 Problems reported by Ralf Wildenhues in:
675 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
677 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
679 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
680 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
681 Don't use the term "thread-safe" to talk about mkdir race
682 conditions, since the problem is more a process than a thread
683 issue. Problem reported by Stepan Kasal in:
684 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
685 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
686 the test for 'install' more closely. Look at MKDIR_P first.
687 Look in the PATH, and at /opt/sfw/bin.
688 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
689 Don't bother to try mkdir -p, since we already check mkdir --version;
690 just look at the version number. (There's no easy way to check
691 for race-free implementations.)
692 * tests/tools.at (autoconf: subdirectories): Adjust to above
693 changes, since MKDIR_P now might end in "/mkdir -p".
695 * doc/autoconf.texi (autoheader Invocation): Mention that the
696 first arg of AC_DEFINE_UNQUOTED must be a literal.
697 Problem reported by Ben Pfaff in
698 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
700 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
701 * doc/autoconf.texi (Special Chars in Variables): New section.
702 (Preset Output Variables): Warn about special chars in CPPFLAGS.
703 (Installation Directory Variables): Quote $(datadir) better.
704 (Limitations of Builtins): Describe some of eval's trickiness.
706 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
707 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
708 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
709 in front of every arg, not just trailing args. Quote apostrophes.
710 (_AC_EVAL_ECHO): New macro.
711 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
712 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
713 removed.
714 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
715 exposed by quoting of eval argument. Put the command on line line
716 so it logs better.
717 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
718 (_AC_PATH_X, AC_PATH_X): Quote more safely.
719 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
720 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
721 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
722 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
723 Use eval more safely.
724 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
725 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
726 to be replaced.
727 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
728 lines, exposed by quoting of eval argument.
730 2006-05-26 Stepan Kasal <kasal@ucw.cz>
731 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
733 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
734 initialization of `ac_cv_exeext', do not override it if it was
735 already set, unless it was set to `no', for compatibility with
736 Autoconf-2.13, and comment this.
737 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
738 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
739 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
740 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
741 Document that this test may be overridden by setting
742 `ac_cv_exeext'.
744 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
746 Revert these two patches:
748 2006-04-06 Eric Blake <ebb9@byu.net>
749 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
750 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
751 2006-04-01.
753 2006-04-01 Stepan Kasal <kasal@ucw.cz>
754 Clean up _AC_COMPILER_EXEEXT* macros.
755 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
756 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
757 ac_file to the name of the default output file and call
758 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
759 initial `rm' of the candidate files...
760 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
761 the same list in subsequent `rm' calls, and for the temporary
762 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
763 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
764 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
765 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
766 no longer needed) by libtool. Make it a cache check.
767 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
768 copied here by mistake.
769 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
770 _AC_COMPILER_EXEEXT.
771 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
772 _AC_COMPILER_OBJEXT directly.
773 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
775 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
777 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
778 Fix description of how the buggy `sed' works.
780 2006-05-25 Noah Misch <noah@cs.caltech.edu>
782 Sync from Automake:
784 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
785 ENOLCK. Only mention `make -j' when applicable. Only raise
786 fatal errors when `make -j' is involved. Improve error message.
788 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
790 * doc/autoconf.texi (Here-Documents): We now know more about
791 the variable expansion in here documents bug.
792 Thanks to Tim Rice and Stepan Kasal.
794 * doc/autoconf.texi (Making testsuite Scripts): Add an example
795 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
797 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
799 * tests/autotest.at (Multiline command from M4 expansion):
800 No failure to be expected if the shell quotes newlines in
801 commands in the `set -x' output. Report by Tim Rice.
802 * THANKS: Update.
804 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
806 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
807 expansion in the here-documents used by config.status, as that
808 runs afoul of the Korn shell version M-12/28/93d bug described in
809 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
810 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
811 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
813 2006-05-23 Jim Meyering <jim@meyering.net>
815 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
816 Fix typo introduced with 2006-04-02 change. It reversed the sense
817 of the test.
819 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
821 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
822 ac_dB slightly, to save bytes in the script.
823 Max out at 50 lines, rather than 96; this is more likely
824 (though not guaranteed) to avoid obscure 'sed' failures.
826 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
828 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
829 `tr -d -' as bad option argument. Work around this by deleting
830 an unrelated character.
831 Report by Tim Rice <tim@multitalents.net>.
833 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
834 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
835 Stepan Kasal <kasal@ucw.cz>
837 * doc/autoconf.texi (Particular Programs): Do not promise that
838 we always prefer the GNU version of the program, and that we
839 search according to PATH; both rules can have exceptions.
840 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
841 AC_PROG_SED. Move descriptions of limitations
842 to the Limitations of Usual Tools section.
843 (Limitations of Usual Tools) <sed>: Mention script length
844 limitations with Solaris /usr/ucb/sed.
845 <grep>: Fix wording for empty alternative. Mention that -c and
846 -l should not be combined, and that -E and -F should not be
847 combined.
849 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
850 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
852 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
853 limits in Solaris 8 /usr/ucb/sed by testing a long script.
855 2006-05-22 Stepan Kasal <kasal@ucw.cz>
857 * doc/autoconf.texi (Defining Symbols): Literal parameter of
858 AC_DEFINE is now passed to m4_pattern_allow.
859 * NEWS: Mention that; likewise for AC_SUBST.
860 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
861 the parameter to m4_pattern_allow.
862 * tests/tools.at: Add a check for that.
864 2006-05-22 Stepan Kasal <kasal@ucw.cz>
866 * lib/autoconf/status.m4: Fix typos.
868 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
870 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
871 only the files that this macro generates.
873 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
875 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
876 the HP-UX sed limitation of 99 commands, labels do not count.
877 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
878 in the comment.
879 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
881 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
883 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
884 Import the following fix from coreutils:
886 2006-01-13 Jim Meyering <jim@meyering.net>
888 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
889 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
890 not double-quote uses of that variable, to accommodate the rare
891 case in which getmntent is available in none of the libraries
892 checked. This happens at least on FreeBSD 5.0.
894 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
896 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
897 ac_config_guess, ac_config_sub, and ac_configure, since evidently
898 some other programs unwisely rely on these undocumented vars.
899 But put in warning comments about them.
900 Problem reported by Ralf Wildenhues in
901 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
902 * NEWS: Document that these variables are intended to go away.
904 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
906 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
907 and set the language to C++ (analogous to the equivalent Fortran
908 tests).
910 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
911 * doc/autoconf.texi (C++ Compiler): Document it.
912 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
913 * NEWS: Update.
915 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
917 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
918 that caused config.status to generate 100-command sed scripts; the
919 portable limit is 99.
921 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
923 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
924 variable `ac_d' instead of `d' to avoid infringing namespace.
925 Report by Ralf Menzel.
927 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
929 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
930 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
931 * tests/tools.at (autoconf: subdirectories): New test, taken from
932 the corresponding problem report by Ralf Wildenhues in:
933 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
935 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
936 Quote some uses of shell variables if they might suffer unexpected
937 globbing. This doesn't fix all instances of quoting problems that
938 I found, just the easy ones that look safe.
939 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
940 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
941 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
942 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
943 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
944 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
945 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
946 Likewise.
947 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
948 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
950 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
952 * bin/autoreconf.in ($help): Reword according to the manual.
953 Suggested by Olly Betts.
955 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
956 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
958 * bin/autoreconf.in: Pass the directory argument to
959 `require_configure_ac'. Fix comment.
960 * tests/torture.at (Configuring subdirectories): Expose this.
961 Reported by Olly Betts.
963 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
965 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
966 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
967 Automake as follows:
969 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
970 `$configure_in' instead of `configure.in', to preserve
971 directory component.
973 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
975 * config/config.guess, config/config.sub, config/texinfo.tex,
976 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
978 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
980 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
981 test for C99 conformance; (bool) 0.5 is an integer constant
982 expression, but (bool) -0.5 is not. Problem reported by Fedor
983 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
985 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
987 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
988 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
989 Warn about obsolete install-sh files. Remove stray sentence
990 fragment and fix cross reference.
991 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
992 install -d; this undoes the 2006-05-10 change.
993 (MKDIR_P): Mark with AN_MAKEVAR.
994 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
995 that we don't require $INSTALL to be thread-safe. Move comments
996 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
997 of AC_PROG_INSTALL. Output a message saying that we're checking
998 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
999 MKDIR_P instead of AC_SUBST.
1000 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1001 Special magic for MKDIR_P, too.
1002 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1003 a dnl.
1004 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1006 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1008 Sync from Automake, as follows:
1010 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1011 * config/install-sh: Initialize IFS, so field splitting isn't
1012 turned off later.
1013 * config/mkinstalldirs: Likewise.
1014 * config/missing: Remove superfluous quotes. Replace all uses of
1015 `[' by `test', for consistency, and for..
1016 * config/missing (sed_minuso, sed_output): New variables.
1017 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1018 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1019 Fixes `missing' to detect `--output' for help2man. Fixes
1020 PR automake/483. Report by Dennis J. Linse.
1021 (autom4te): Document in `missing --help'.
1023 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1025 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1026 * config/install-sh: Don't use 'path' to talk about file names,
1027 as per GNU coding standards. Close a race condition reported by Ralf
1028 Wildenhues and Stepan Kasal. There is still a race condition
1029 on hosts that predate Posix 1003.1-1992, but we can't help this.
1030 Don't mishandle weird characters like space on pre-Posix hosts.
1031 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1032 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1033 AC_PROG_MKDIR_P from AS_MKDIR_P.
1034 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1035 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1036 earlier editions are not (including Automake 1.8.3).
1037 Do not suggest mkinstalldirs for thread-safety.
1038 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1039 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1040 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1041 presence of special characters and race conditions.
1042 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1043 in Autoconf's name space.
1045 2006-05-10 Bruno Haible <bruno@clisp.org>
1046 and Paul Eggert <eggert@cs.ucla.edu>
1048 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1049 from Automake with minor changes.
1050 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1052 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1054 * config/install-sh: Update to Automake CVS version, as follows:
1055 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1056 * lib/install-sh: Simplify the expr implementation of dirname.
1057 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1058 * lib/install-sh: Handle --, and diagnose unknown options.
1060 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1062 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1063 `./autom4te' to create `./testsuite', since the `all' target
1064 will ensure its presence, but `installcheck' should not create
1065 the uninstalled wrappers.
1067 * tests/torture.at (Unusual Automake input files): Skip if we
1068 detect automake < 1.8.
1070 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1072 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1073 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1074 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1075 * NEWS: Update.
1077 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1079 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1080 munge (multiple) white space and other oddities.
1081 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1082 single quotes in variable assignment.
1083 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1084 and similar failures by adding multiple spaces, tabs, and other
1085 special characters.
1086 Report and different test suggested by Francesco Romani
1087 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1089 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1090 single quotes, we only need to search for single quotes; this
1091 both simplifies the search pattern, and makes us less
1092 susceptible to `echo' variations for arguments not containing
1093 single quotes.
1094 (_AC_ARG_VAR_VALIDATE): Likewise.
1096 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1098 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1099 `$*' and IFS concatenation issue with traditional shells and
1100 bash-2.04. Report by Seanster@Seanster.com.
1102 2006-05-03 Bruno Haible <bruno@clisp.org>
1104 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1105 precisely which Mac OS X versions have the od problem.
1107 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1109 * doc/autoconf.texi: Use @option systematically.
1111 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1112 and Bruno Haible <bruno@clisp.org>
1114 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1115 about 'od'.
1116 (Integer Overflow): Mention the special case of integer division
1117 overflow.
1119 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1121 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1122 traditional shells like the Solaris one that do not use the
1123 first IFS character for assembling `$*'.
1124 Prompted by a related report from autoconf_bug@nro.ca.
1126 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1127 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1129 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1130 Mention more problems with the -e option.
1132 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1134 * NEWS: Typo.
1135 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1137 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1138 in URLs to improve DVI formatted output (requires texinfo 4.6).
1139 (System Services, Systemology, Shellology): Likewise.
1140 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1141 output.
1143 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1144 continuous text.
1145 (Runtime): Fix macro argument names to match description:
1146 `action-if-found' -> `action-if-true' and similarly.
1147 (Obsolete Macros): Likewise.
1148 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1149 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1150 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1152 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1154 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1156 * ChangeLog: Typo.
1157 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1158 DVI output.
1160 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1163 /bin/sh set unsorted output.
1164 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
1165 * tests/local.at: Likewise.
1167 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
1169 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1170 (Integer Overflow, Null Pointers, Buffer Overruns):
1171 (Floating Point Portability, Exiting Portably): New sections.
1172 (Writing Test Programs): Fix some langauge. Recommend exiting
1173 with status 1, not merely nonzero. Clarify exit declaration.
1174 (Run Time): Move C exit status stuff to new Exiting Portably section.
1175 (Systemology): Mention Posix and levenez. Update v7 reference.
1176 (Portable Shell): Mention the Posix shell.
1178 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1180 * bin/autoconf.as (me): Replace by as_me.
1182 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1184 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1185 since as_me isn't set yet.
1187 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1189 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1190 a few minor bugs in this area.
1192 * doc/autoconf.texi (Programming in M4sh): Comment out the
1193 documentation of AS_BASENAME, for now.
1194 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1195 (Limitations of Builtins) <basename>: Do not refer to
1196 AS_BASENAME.
1197 * bin/autoconf.as (me): Don't use AS_BASENAME.
1198 (dir): Remove the unused variable.
1199 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1200 AS_DETECT_REQUIRED. All uses changed.
1201 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
1202 All uses changed.
1203 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1204 (AS_BASENAME): Use "basename --" to protect against leading "-".
1205 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1206 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1207 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1208 (_AS_DIRNAME_PREPARE): Likewise.
1209 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1210 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1211 (AS_DIRNAME): Use "dirname --".
1213 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1215 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1216 of "run time" and "run-time" changed to "runtime", for consistency.
1217 * lib/autoconf/fortran.m4: Likewise (in comment).

1219 * lib/autoconf/general.m4: Likewise.
1220 * lib/autoconf/headers.m4: Likewise.
1222 * doc/autoconf.texi (Run Time): Document the exit status situation
1223 with more accuracy and detail.
1225 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1227 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1228 Archive is not officially `GNU' any more. Update URL.
1229 (Defining Directories): Likewise
1230 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1232 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1234 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1235 newline from the `trap' code to finish `config.log'; the NetBSD
1236 /bin/sh resets the exit status after an empty command, as
1237 documented in doc/autoconf.texi.
1238 Reported by Dalibor Topic <robilad@kaffe.org>.
1240 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1242 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1243 Suggested by Bruno Haible.
1245 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1247 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1248 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1249 Instead, just list the shells that we know work.
1250 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1251 changed. Be more cautious about the _cv_ variable.
1252 * tests/tools.at (Syntax of the shell scripts): Check the
1253 _cv_ variable once, at first, to avoid an internal autoconf error
1254 when sh -n does not work.
1256 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1258 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1260 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1262 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1263 use ">&-" since we're only 99.999% sure that this is portable,
1264 and since the MinGW bug is fixed in a different way.
1265 * lib/autotest/general.m4 (AT_INIT): Likewise.
1267 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1269 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1270 before opening config.log, to avoid hitting a bug on MinGW.
1272 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1274 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1275 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1276 This works around a MinGW bug reported by Eric Paire.
1277 Make sure that all writes to the log file append to it,
1278 rather than possibly losing data.
1279 * lib/autotest/general.m4 (AT_INIT): Likewise.
1281 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1283 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1284 description.
1286 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1288 * NEWS: Update.
1290 * configure.ac (AC_INIT): Bump to 2.59d.
1292 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1294 Version 2.59c.
1296 * Makefile.maint (news-date-check): Do not require a leading `*'
1297 before the release date in NEWS.
1299 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1300 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1302 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1303 the instantiated file do not contain the string 'datarootdir'
1304 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1305 @mandir@, replace the reference '${datarootdir}' by the value.
1306 * tests/torture.at (datarootdir workaround): New test.
1307 * NEWS: Advertise this temporary fixup.
1308 Based on a patch by Bruno Haible, reported and analyzed by
1309 Paul Eggert and Noah Misch.
1311 2006-04-12 Eric Blake <ebb9@byu.net>
1313 * tests/autotest.at (Debugging a failed test): Fix comment.
1315 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1317 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1318 all the changes since 2006-04-07.
1320 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1322 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1323 succeeded, but `ln -s file dir' failed, take care to remove the
1324 leftover target before the next test, to prevent its spurious
1325 failure; also make sure `ln file dir' works before selecting it.
1326 Thanks to Keith Marshall for pointing this out.
1327 * THANKS: Update.
1329 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1330 assignments in `at_debug_args', so that we put them correctly
1331 in the `run' script.
1332 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1333 Reported by Eric Blake.
1335 2006-04-11 Eric Blake <ebb9@byu.net>
1337 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1338 top-level tests after micro-suite has been run. Used in...
1339 (Debugging a successful test, Debugging script and environment),
1340 (Debugging a failed test): ...these new tests. The first of these
1341 is fixed by...
1342 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1343 macro, split out from...
1344 (AT_INIT): ...here, so that using -d also generates a run script.
1345 Document that -d inhibits top-level logging.
1346 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1347 inhibits top-level logging; debug scripts are created.
1349 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1350 check.
1351 * tests/autotest.at (Empty test, Empty check): New test to check it.
1353 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1354 from gcc.
1356 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1358 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1359 the files if a problem appears. Make the empty *.at files
1360 read-only, too. Proposed by Ralf Wildenhues.
1362 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1364 * config/Makefile.am: Add comment to force updated Makefile.in.
1366 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1367 space only patch to this file, this patch causes the Makefile.in
1368 files that include freeze.mk to be updated, and thus have a
1369 newer time stamp again, which in turn makes a pristine CVS
1370 checkout have correct time stamps.
1372 * Makefile.maint (cvs-sv): New macro, to be used..
1373 (config.guess-url_prefix, config.sub-url_prefix)
1374 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1375 point to CVS text checkout of Gnulib files.
1376 (copyright-check): Bump current year.
1377 (announcement): Do not hard-wire `./announce-gen'.
1378 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1379 correctly.
1380 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1381 `chmod +x'.
1382 (wget_files): Update config.guess, config.sub, texinfo.tex by
1383 `wget-update', now that their URLs work again.
1385 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1387 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1388 Problem noted by Paul D. Smith.
1390 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1392 * doc/autoconf.texi: Remove unused words from word list.
1393 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1394 .x-sc_trailing_space: New files.
1396 * doc/standards.texi: Sync from gnulib.
1398 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1399 `LIBOBJDIR' as experimental.
1401 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1402 with a target directory; it's internally implemented as `cp'
1403 anyway, but since Autoconf advertises the possibility to use
1404 a target directory when LN_S is `ln -s', we need to find out.
1405 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1406 analyzed by Keith Marshall <keith.marshall@total.com>.
1408 * THANKS: Update.
1410 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1412 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1413 confdefs.h as-is. In general, if it has backslash-newline or the
1414 like, then it doesn't work either to sort or to remove empty
1415 lines.
1417 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1419 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1421 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1423 * lib/autom4te.in (Automake-preselections): Preselect
1424 _AM_SUBST_NOTMAKE.
1426 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1428 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1429 apostrophe within a single-quoted string, as this is the usual
1430 tradition and is easier to read than '"'"'. Don't rely on the
1431 shell treating "$/" like '$/'. Use a more-consistent indenting
1432 style for the trap.
1434 2006-04-09 Eric Blake <ebb9@byu.net>
1436 * tests/autotest.at (Backquote command substitution),
1437 (Multiline backquote command substitution): Remove mistaken
1438 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1439 applied...
1440 (Parenthetical command substitution, Multiline parenthetical
1441 command substitution): here.
1443 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

1473 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1474 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1475 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1476 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1477 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1478 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1479 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1480 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1481 (Coding Style). Don't mention m4_expand_once.

1500 New macros.
1502 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
1503 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
1505 2006-04-08 Stepan Kasal <kasal@ucw.cz>
1507 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1508 of the warning introduced by the 2001-08-28 change.

1516 that contains braces.
1518 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1520 Revert the patch from 2006-04-01 and only improve
1521 _AS_DETECT_BETTER_SHELL:
1523 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1524 skip nonexistent directories.
1525 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1526 only shell candidates which exist.
1527 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1528 * lib/autotest/general.m4 (AT_INIT): No need to give three
1529 parameters to _AS_PATH_WALK.
1531 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1532 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1534 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1535 distinguish m4sugar macros.
1536 * tests/tools.at (autoupdating with aclocal and m4_include):
1537 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1538 test case by Noah Misch <noah@cs.caltech.edu>.
1540 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1542 Revert my change from 2006-03-17, in other words:
1543 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1544 and DUALCASE=1.
1545 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1546 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1547 it is set.
1549 2006-04-07 Eric Blake <ebb9@byu.net>
1551 * doc/autoconf.texi (Programming in M4sh): Document that
1552 AS_MKDIR_P exits the script on failure.
1553 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1555 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1557 * config/elisp-comp, config/install-sh, config/mdate-sh,
1558 config/missing, config/mkinstalldirs: Sync from Automake.
1560 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
1561 from Automake.
1563 * doc/make-stds.texi: Sync from gnulib.

1567 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1568 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

1572 Eric Blake <ebb9@byu.net>,
1573 Paul Eggert <eggert@cs.ucla.edu>,
1574 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1576 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1577 whether `set' quotes correctly: redirect stderr of the tested
1578 `set', and use a subshell, for Ultrix; use `sed' instead of
1579 `grep' for zsh `set' which may write binary output; match only
1580 at the beginning of a line, to avoid false positives.
1581 In order to avoid false positives by unrelated variables with
1582 multiline content, put the dump algorithm in a subshell and
1583 unset all variables containing newlines (except some which are
1584 special to the shell). Warn about cache variables that are
1585 unset.
1587 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1589 * config/config.guess, config/config.sub, config/texinfo.tex:

1598 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1599 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1600 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1601 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1603 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1604 shell issue with double-quoted command substitutions of native
1605 commands.
1606 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
1607 Marshall.
1609 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

1624 2006-04-06 Stepan Kasal <kasal@ucw.cz>
1626 * tests/Makefile.am (maintainer-check-posix):
1627 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1629 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1630 ac_config_<foo>s again, sometimes normalized, sometimes not.
1631 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1632 (AC_CONFIG_COMMANDS): Do not do so here.
1633 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1634 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1635 2005-07-25 rewrite. Noticed by Noah Misch.
1637 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1638 _AC_PRESERVE_HELP_ORDER, ...
1639 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1641 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1642 inside m4_expand_once; it is redundant.
1644 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1645 for --help from Cygnus `configure.'
1647 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
1649 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
1650 on a patch proposed by Ralf Wildenhues.
1652 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1654 * lib/autoconf/status.m4: Replace <space>''<tab> with
1655 <tab><space> where this makes sense.
1657 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
1658 Noah Misch <noah@cs.caltech.edu>
1660 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1661 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1662 * doc/autoconf.texi (Help Formatting): New node.
1663 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1665 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1667 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1668 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1669 lib/autoconf/types.m4, lib/autotest/general.m4,
1670 tests/mktests.sh, tests/torture.at: White space cleanup:
1671 remove some SPACE before TAB, or add quoting ('' or @&t@).
1673 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1675 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1677 2006-04-05 Eric Blake <ebb9@byu.net>
1679 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1680 empty test suite works.
1681 * tests/autotest.at (Empty test suite): Remove xfail.
1683 2006-04-05 Noah Misch <noah@cs.caltech.edu>
1685 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
1686 TAGS to ac_config_<foo>s.
1687 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1688 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1689 normalizing it, consistent it with previous releases.
1690 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1692 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1694 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1695 Use simplified args that Eric Blake originally suggested.
1697 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1699 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1700 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1701 Use 'comm' rather than N instances of grep; this also fixes a bug
1702 whereby substrings were incorrectly matched, causing us to not
1703 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1704 (exclude_list): Exclude empty macros.
1705 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

1710 Switch from grep to awk syntax.
1711 (ac_exclude_script): Renamed from ac_exclude_egrep.
1712 (au_exclude_script): Renamed from au_exclude_egrep.
1714 2006-04-04 Noah Misch <noah@cs.caltech.edu>
1716 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
1717 a subdirectory subject to Cygnus `configure'.
1718 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
1720 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
1721 report request when we have no AC_PACKAGE_BUGREPORT.
1723 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1725 * THANKS: Update.

1728 generated files.
1730 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
1731 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a

1742 (output): Emit AC_CONFIG_SUBDIRS as needed.
1743 * tests/autoscan.at (autoscan): Remove XFAIL.
1745 2006-04-03 Noah Misch <noah@cs.caltech.edu>
1747 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
1749 2006-04-03 Eric Blake <ebb9@byu.net>
1751 * THANKS: Add myself.
1753 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1755 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
1756 to log, point to testsuite output tree.
1758 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
1760 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
1761 * doc/autoconf.texi (Function Portability): Mention that C++
1762 has trouble with 'exit'.
1763 (Guidelines): Test programs shouldn't use 'exit'.

1765 Remove; all uses removed.
1766 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

1786 Clean up _AC_COMPILER_EXEEXT* macros.
1788 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1789 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1790 ac_file to the name of the default output file and call
1791 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1792 initial `rm' of the candidate files...
1793 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1794 the same list in subsequent `rm' calls, and for the temporary
1795 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1796 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1797 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1798 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1799 no longer needed) by libtool. Make it a cache check.
1800 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1801 copied here by mistake.
1802 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1803 _AC_COMPILER_EXEEXT.
1804 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1805 _AC_COMPILER_OBJEXT directly.

2577 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2578 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2579 by the function rather than ignoring it.
2580 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2581 comparing its address. Intel's interprocedural optimization was
2582 outsmarting the old heuristic. Problem reported by

2600 Stepan Kasal <kasal@ucw.cz>
2602 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2603 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2604 make its content writable before removing it. Remove an errorneous
2605 comment from the end, where the logs of the failed tests are copied
2606 to the main log file.
2608 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2610 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

2615 problems if the testsuite were running too fast.
2617 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2619 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

2631 suggested by Ben Elliston. Handle weird characters correctly.
2633 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2635 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2636 calls, so that the final expansion of this macro is shorter.
2637 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2638 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2639 the cleanup there. Use AS_VAR_* macros, to be more general.
2640 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2642 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2644 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

2659 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2660 The previous patch didn't work, so try a better one.
2662 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2664 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2665 in the example. Reported by Bruno Haible.
2666 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2667 "if $undefined_var;" succeeds with my shell.
2669 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2670 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2671 but change the m4_divert_text to m4_divert_once.
2673 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2675 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):

2677 The bug is present in at least Solaris 8 through 10.
2679 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2681 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2682 some evil values and relying on the fact that $* concatenates the
2683 parameters by the first character from IFS.
2685 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2686 Stepan Kasal <kasal@ucw.cz>
2688 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2689 first header appears, define AH_HEADER.
2690 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2691 Update limitations about when to call AC_CONFIG_HEADERS.
2692 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2693 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2694 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2695 ``Configuration Actions''; fix their index entries.
2697 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2698 options correctly. Process N-M as M-N if M is smaller than N.
2699 Process ranges correctly so that N-N will run only N.
2700 Sort and uniquify the tests that will be run. If there is more
2701 than one test, reinsert the banners for the tests.
2702 * tests/autotest.at (Keywords): Unmark XFAIL.
2704 2005-08-23 Stepan Kasal <kasal@ucw.cz>

2707 before passing the macro name to AH_TEMPLATE.
2709 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2710 now opens log after option processing; in particular, --version
2711 and --help do not touch config.log.

2723 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2724 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2725 Language cleanup.
2727 * doc/autoconf.texi (Defining Symbols, Changed Results):
2728 Prepend to LIBS, not append, in examples.
2730 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2732 When building in place, set srcdir="."; suggested by Tim Van Holder.
2734 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2735 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2736 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2737 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2738 does not mean "no --srcdir option".
2740 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2745 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2747 * tests/autotest.at (Keywords): Test keywords combinations.
2749 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2751 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2752 add "2>&1"; gzip 1.2.4 prints help on stderr.
2754 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2756 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2757 was pushdef'ed twice while popped only once. Push it only once.
2758 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2760 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2762 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
2763 prefixed by mere "===", not "configure: === ".
2765 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
2767 * Makefile.maint: Update from Bison.
2769 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2770 "<tab>" in comment, so that the point is understandable.
2772 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2774 Rewrite substantial part of lib/autoconf/status.m4.
2775 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2776 and CONFIG_COMMANDS are not processed in four separate loops.
2777 Instead, there is one main loop. This alows that the common code
2778 is expanded only once, thus config.status (and configure) is smaller.
2780 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2781 the AC_LIST_FILES and cousins macros are no longer used.
2783 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2784 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2785 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2786 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2787 contain the initialization, nor the for loop, nor the associated
2788 commands; all these go to ...
2789 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2790 _AC_OUTPUT_CONFIG_STATUS.
2791 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2792 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2793 (_AC_OUTPUT_FILE): The creation of the sed script ...
2794 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2795 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2796 _AC_OUTPUT_MAIN_LOOP.
2797 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2798 _AC_CONFIG_COMMANDS): Use ...
2799 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2800 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2801 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2802 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2803 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2804 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2805 ... new macros.
2806 (_AC_CONFIG_UNIQUE): Update.
2807 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2808 Replaced by this ...
2809 (_AC_LIST_TAGS): ... new common macro.
2810 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2811 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2812 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2813 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2814 this didn't belong to the `config commands' section.
2815 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2816 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2817 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2818 to the `config commands' section either.
2819 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2820 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2822 ... and many changes to the comments nearby.
2824 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2825 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2826 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2827 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2828 (#define header templates): The comment at the top of the generated
2829 header now includes the name(s) of the source file(s).
2831 Several unrelated small changes:
2833 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2834 parameter to AC_DIAGNOSE.
2835 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2836 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2837 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2838 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2839 with AU::AC_OUTPUT.
2840 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2841 in AC_OUTPUT doesn't double-quote it either.
2842 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2843 parameters.
2845 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2847 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2848 versions of Portland Group compiler produce single- and double-quoted
2849 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2850 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2852 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2854 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2855 This is a corrected version of yesterday's patch.
2857 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2859 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2860 path, too; insert a "===" to emphasize the line.
2862 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2863 ac_cv_build_alias to ac_build_alias.
2864 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2866 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2867 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2868 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2869 (AC_ARG_VAR): ... here.
2870 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2871 target_alias.
2873 Keep a list of all precious variables and process them with one simple
2874 for loop, instead of expanding all commands, or, OTOH, complicated
2875 processing of output of "set".
2876 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2877 variable names in new macro...
2878 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2879 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2880 a loop to assign all ac_env_* and ac_cv_env_* variables.
2881 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2882 to INIT_PREPARE.
2883 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2884 its value to shell variable ac_precious_vars and call
2885 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2886 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2887 _AC_ARG_VAR_VALIDATE.
2889 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2890 and the AC_SUBSTs ...
2891 (AC_INIT): ... here.
2893 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2894 the ac_subst_files section in config.log.
2896 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

2905 Fix problems reported by Nicolas Joly.
2906 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
2907 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2908 They are generated by the Tru64 v5.1B shell.
2910 2005-07-05 Stepan Kasal <kasal@ucw.cz>
2912 Fix my changes from 2005-07-01; reported by Noah Misch.
2913 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2914 description, the macro now accepts only a single tag.
2915 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
2917 Fix cases when the varsions of Autoconf and Autotest don't match.
2918 Reported by Noah Misch.
2919 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
2920 at_top_builddir, for compatibility with older autotest.
2921 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2922 is not set, use at_top_builddir, for compatibility with older
2923 versions of autoconf.
2925 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2927 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2928 Problem reported by Patrick Welche.
2930 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2932 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2933 sed substitution command, so that we allow | in program prefixes
2934 and program suffixes. (& is a problem anyway; we're not fixing
2935 that here.)
2936 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2937 configure_input, top_builddir, srcdir, etc.
2938 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2939 PATH_SEPARATOR in AUTOTEST_PATH.
2941 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2943 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
2944 for loop over config.site files using `set', to allow
2945 directory names containing IFS characters.

2949 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2950 directories with weird names. Apparently some people like living

2971 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2972 document to output the default config_* lists to config.status.
2973 Don't recognize option --file, if the functionality is not there.
2974 Likewise for --header; moreover, recognize --he and --h as shortcuts
2975 for --help in that case.
2977 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2978 matches the order of execution. No code changed.

2999 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
3000 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3001 (AC_SUBST): Call it.
3002 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3003 the directory specific variables; but don't call it for configure_input.
3005 2005-06-28 Derek Price <derek@ximbiot.com>
3007 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3008 addition.
3010 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3012 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3013 directory have inherent problems with special characters like spaces,
3014 due to limitations in Make syntax. Problem reported by Alexandre
3015 Duret-Lutz.
3016 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

3029 from Justace Clutter.
3030 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
3031 variable into diagnostic. Make the diagnostic an error, not a warning,
3032 because we really don't support spaces and suchlike in dir names.
3033 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3034 Don't worry about backslashes in srcdir; it can't happen now.
3035 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
3036 Simplify ac_optarg handling.
3037 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

3045 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3047 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3048 that '\|' is not allowed in BREs; recommend using newline separated
3049 list of patterns instead of multiple -e options.
3051 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
3053 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

3059 2005-06-21 Stepan Kasal <kasal@ucw.cz>
3061 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3062 b, t, r, w commands require single space, while : cannot have any.
3063 (Special Shell Variables): Fix sed code this in the example.
3064 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3065 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3067 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3068 expand to the empty list. Don't use two pairs of m4_changequote,
3069 it's not necessary.
3071 2005-06-20 Derek Price <derek@ximbiot.com>
3073 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
3075 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
3077 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3078 * doc/autoconf.texi:
3079 Don't mention Solaris versions so much, if a
3080 problem is common to all extant versions of Solaris. Say "SunOS
3081 4" instead of "SunOS" for SunOS 4.
3082 (awk): Mention more of the limitations of traditional Awk.
3083 (cat): Don't talk about cat -v.
3085 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
3087 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
3088 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
3089 but the implementation is entirely different and is designed
3090 to be compatible with glibc strverscmp.
3091 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
3093 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3094 on Mac OS X 10.4 reported by Peter O'Gorman in:
3095 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
3096 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
3097 Use shell builtins rather than 'expr', to work around expr bug.
3099 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3101 * doc/autoconf.texi: "filesystem" -> "file system".
3102 "behaviour" -> "behavior".
3103 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
3104 * lib/autoconf/general.m4: Omit blank after ":" sed command,
3105 as per POSIX.

3108 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
3110 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
3111 (.x.1): Ignore the time stamp in the .TH line when deciding whether
3112 to update the man page. That way, we don't have to check in new
3113 man pages every month.
3115 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
3116 quotes and backslashes. Patch from Derek Price.
3118 2005-06-10 Derek Price <derek@ximbiot.com>
3120 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
3121 AS_TR_SH.
3123 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
3125 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3126 -u, since it outputs chatter if the input files are the same.
3127 Problem reported by Ralf Menzel.
3129 2005-06-08 Derek Price <derek@ximbiot.com>
3131 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3132 renaming them since they are about to be redefined anyhow.
3134 2005-06-08 Derek Price <derek@ximbiot.com>
3136 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3137 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3138 Move m4_undefine to alphabetical order.
3140 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3142 * README: Recommend GNU M4 1.4.3 or later.
3143 * doc/autoconf.texi (Introduction): Likewise.
3144 Reword to avoid some formatting glitches.
3145 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3146 Clarify explanation of HP compiler bug.
3147 Redo example output tp match current CVS snapshot.
3148 Use @example.org in email addresses when the examples
3149 might get inadvertently cut-and-pasted into user code.
3150 Remove example of autom4te usage that doesn't seem to work now.
3151 Use modern AC_INIT (except when the example is meant to be
3152 shown with Autoconf 2.13).
3153 Update ksh info for Solaris 9 and later.
3154 KB -> kB.
3155 Modernize description of Automake versions a bit.
3156 Don't claim a future version of Autoconf is near.
3157 * doc/install.texi: Reword to avoid some formatting glitches.
3159 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3161 * doc/autoconf.texi: Add [] to examples, so that the manual
3162 follows its own advice about quoting better.
3163 Reword to avoid some formatting glitches.
3164 * doc/installt.exi: Reword to avoid some formatting glitches.
3166 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3167 Tru64 ksh pattern matching bug. Reported against Libtool by
3168 Albert Chin <libtool@mlists.thewrittenword.com> and
3169 Nicolas Joly <njoly@pasteur.fr>.
3171 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3173 m4_cdr of one-member list was [[]] (one-member list containing an
3174 empty string) instead of [] (an empty list. Callers were skewed to
3175 match this misbehaviour. As a consequence of this:
3176 - m4_foreach([x], [], [foo]) expanded to `foo', while
3177 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3178 This bug has been fixed:
3180 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3181 expand to an empty string; print error msg if called without
3182 an argument list.
3183 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3184 misbehaviour; handle [] and [[]] correctly.
3186 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3188 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
3189 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
3190 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
3192 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3194 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3195 swallow records with more than 99 fields.
3196 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3197 parse the long line.
3199 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3201 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3202 swallow literals longer than 399. Reported by Ralf Wildenhues.
3203 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
3204 to workaround this limitation.
3206 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3208 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3209 to gfortran, and make these the first two compiler names
3210 checked (following the general autoconf preference for gcc).
3212 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3214 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3215 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3216 (testsuite): Make sure autotest.m4f is up-to-date before using it.
3218 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
3220 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3221 expression of unbounded size when processing the --list
3222 option. This runs afoul of a limit of 399 bytes per regular
3223 expression on AIX. Problem reported by Ralf Wildenhues.
3225 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
3227 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
3228 * doc/autoconf.texi (Particular Headers): Reword example
3229 for multiline stdbool replacement.
3230 (Setting Output Variables): Reword text a bit. Don't
3231 give all the details about |#_!!_#|.
3232 Reword description of line replacement.
3234 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3236 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3237 now contain newlines, and substituted files must be referenced on
3238 a line alone; the sed scripts to substitute them are now very
3239 different.
3240 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3241 commands can be put in a sed script portably.
3242 * doc/autoconf.texi (Setting Output Variables): Document above
3243 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3244 use of multiline substitution.
3245 * tests/torture.at: No longer expect substitution of newline to fail.
3247 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
3249 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
3250 From Ralf Menzel (trivial change).
3252 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
3254 * tests/local.at: Don't attempt to check for negated character
3255 classes in shell scripts. The test was too brittle.
3257 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3259 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3260 * doc/autoconf.texi (Limitations of Builtins): Document this
3261 limitation.
3263 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3265 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3266 common code; used in many places in the tree.
3267 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
3268 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
3270 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
3272 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
3273 messages when ac_unique_file is not found.
3274 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3275 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3276 commands, for consistency with AC_MSG_ERROR and such.
3278 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3280 * bin/Makefile.am: Merge the two rules for creating scripts.
3282 2005-05-23 Stepan Kasal <kasal@ucw.cz>
3284 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
3285 obsolete; it was never documented.
3286 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
3288 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3290 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3291 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3292 (ac_top_builddir): ... this ...
3293 (ac_top_build_prefix): ... to this; the old name is also kept, for
3294 backward compatibility.
3295 (ac_top_builddir_sub): New variable, without the trailing slash,
3296 always nonempty.
3297 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3298 * doc/autoconf.texi (Configuration Actions): Rename
3299 ac_top_builddir to ac_top_build_prefix.
3300 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
3301 at_top_builddir to at_top_build_prefix.
3302 * lib/autotest/general.m4 (AT_INIT): Likewise.
3304 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3306 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
3307 of confdefs.h .
3309 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3311 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3312 argument to m4_foreach. I guess it was necessary in the past,
3313 but I think it's a no-op now.
3315 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3317 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3318 ``cat <<_ACEOF'' commands to one.
3319 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3320 * lib/autoconf/status.m4: On various places, use expr instead of
3321 ``echo|sed.''
3322 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3323 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3324 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3325 a range.
3326 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3327 the wrong patterns between ``case'' and ``esac.'' The previous
3328 code had false positives.
3330 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3332 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3333 as on 2005-05-02.
3334 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3335 Mention LIBOBJDIR.

3375 2005-05-13 Stepan Kasal <kasal@ucw.cz>
3377 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
3378 check.
3379 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3380 enough arguments, similarly as in m4_bpatsubsts.
3382 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3384 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
3385 of absolute paths.
3387 2005-05-11 Stepan Kasal <kasal@ucw.cz>
3389 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3390 for absolute directory names in one loop.
3391 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3392 abbreviations of --version and --debug.
3394 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3396 * doc/autoconf.texi (Autoconf Language): Be more precise about
3397 quoting rules. Problems noted by Stepan Kasal.
3398 Also, throughout this document, be more careful about white space.
3399 "blank", "white space", and "space" all have different meanings
3400 and we should be careful to say what we mean.
3402 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3404 Fix C++ related problems reported by Werner Lemberg.
3405 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3406 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3407 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3408 avoid problems with C++ and throw.
3409 * tests/compile.at: .cpp, not .cc.
3411 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3413 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3415 * doc/autoconf.texi (Generic Functions): Typos.
3417 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3419 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3420 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3421 set by latest automake.
3423 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3425 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3426 outputs 0 on GNU/Linux these days.
3428 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3430 * doc/autoconf.texi (Autoconf Language): Add more description
3431 about quoting heuristics.
3432 (Limitations of Builtins): Describe "set -" problems.
3434 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3436 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3437 not newline.
3439 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3440 by AC_DEFINE; it was a mistake.
3441 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3443 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3445 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3447 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3449 * doc/autoconf.texi (External Software): Quadrigraphs are not
3450 processed correctly in AS_HELP_STRING; avoid this in the examples.
3451 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3452 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3453 comment and reduce m4_default([foo], []) to [foo].
3454 (m4_strip): Update the explanation.
3456 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3458 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3459 Remove core.conftest.* too; it's generated by Tru64 5.1.
3460 Problem reported by Jennis Pruett.
3461 * lib/autoconf/functions.m4
3462 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3463 Don't bother to remove core files; AC_RUN_IFELSE should do that
3464 for you.
3466 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3468 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
3470 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
3472 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
3473 Report from Horst Wente.
3475 2005-04-15 Stepan Kasal <kasal@ucw.cz>
3477 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
3478 the comment.
3480 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3482 * doc/autoconf.texi (External Software, Package Options): Add
3483 examples showing how to implement --with-* and --enable-* options.
3485 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3487 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3488 as well as configure.in. Problem reported by Gregorio Guidi.
3490 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3492 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3493 pattern for alloca snippet.
3495 2005-04-04 Stepan Kasal <kasal@ucw.cz>
3497 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

3503 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3505 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3506 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3508 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3510 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3511 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3512 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3513 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3514 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3516 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3518 * NEWS: The configure command now warns you if you attempt to use
3519 a directory whose name contains a special character like space,
3520 newline, or "\".
3521 * doc/autoconf.texi (Installation Directory Variables): Allow
3522 "," in file names. Do not use \@; it's not a portable regexp.
3523 * bin/Makefile.am (edit): Likewise.
3524 * lib/Makefile.am (edit): Likewise.
3525 * tests/Makefile.am (edit): Likewise.
3526 * tests/semantics.at: Likewise.
3527 * tests/torture.at: Likewise.
3528 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3529 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3530 * doc/autoconf.texi (File System Conventions): Warn about
3531 unportable file names.
3532 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3533 (AC_INIT): Use it.
3534 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3535 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3536 ac_pwd, and quote srcdir.
3537 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3539 * doc/autoconf.texi: Fix some systematic formatting problems.
3540 ".)" needs a following @: if not at the end of a sentence, and
3541 similarly for "!)". "etc." should be preceded by a comma.
3542 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3544 2005-03-22 Bruno Haible <bruno@clisp.org>
3546 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3547 argument is often called 'build-aux'.
3549 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3551 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3552 macro AC_TRY_LINK is obsolete.
3553 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3554 `AC_CONFIG_FILES'.
3556 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3558 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3559 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3560 from a Common Lisp's `cl'.
3561 (AC_PROG_CXX): Behave according to the documentation: don't
3562 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3563 make the variable CCC precious; use `cl.exe', not `cl'.
3565 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3566 Alexandre Duret-Lutz <adl@gnu.org>
3568 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3569 /dev/null, as "configure" shouldn't read stdin, and this insulates
3570 us from problems (e.g., when testing for "cl"). Also, do this
3571 redirection before invoking "hostname" or "uname", and keep the
3572 original input stream available via...
3573 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3574 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3575 bother with "</dev/null" since it's now done at the top of
3576 'configure'.
3577 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3578 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3579 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3580 * doc/autoconf.texi (File Descriptor Macros): New section.
3581 (Printing Messages): Mention it.
3582 * tests/base.at (Input/Output): New test.
3584 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3586 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3587 newline if neither \c nor -n work, as that would output two
3588 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3590 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3592 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3593 This causes that any required macros inside will get before the if.
3594 * doc/autoconf.texi (autom4te.cache): A typo.
3596 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3598 Undo previous change, except keep the change to
3599 lib/autoconf/programs.m4 that replaced grep with shell
3600 pattern-matching. This is because net-snmp configure reads stdin.
3601 Reported by Noah Misch.
3603 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3605 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3606 from /dev/null, as "configure" shouldn't read stdin, and this
3607 insulates us from problems (e.g., when testing for "cl").
3608 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3609 before invoking "hostname" or "uname".
3610 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3611 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3612 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3613 "</dev/null" since it's now done at the top of 'configure'.
3614 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3615 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3616 Also, replace grep with shell pattern-matching, to save a process.
3618 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3620 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3621 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3622 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3623 compiler.
3625 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3627 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3628 grep -q isn't portable. Improve grep -s explanation.

3681 excess test name quoting.
3682 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3683 CPPFLAGS to `configure' instead of setting it in `configure'.
3685 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3686 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3687 on some platforms.

3721 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3723 Try not to generated lines of unlimited length, as POSIX places a
3724 2047-byte limit on line length of portable text files.
3725 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3726 Use newline as a separator, not space.

3729 space.

3739 * doc/autoconf.texi (Special Shell Variables): Mention _,
3740 BIN_SH, DUALCASE. Say that variables other than "status" are safe
3741 if they contain a lower-case letter. The DUALCASE problem was
3742 reported by Ralf Wildenhues.
3744 * bin/autoconf.as: Don't exit with status 0 after write failure
3745 with --help or --version.
3746 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

3784 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3785 Update the long comment explaining it.
3787 m4_require no longer writes an ``is required by'' line to the
3788 execution stack. It contains only one bit of non-redundant
3789 information: that the macro was required, not called. And even
3790 this bit is useless in most situations: have you ever met a macro
3791 which both calls and requires the same macro?
3793 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3794 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3801 (_m4_require_call): Use it.
3802 * tests/m4sugar.at (m4_require): Expect output without the
3803 ``is required by'' messages.
3805 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3807 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3808 rather than x for expr.
3810 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3811 this is safe.
3812 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
3813 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

3825 from masters, so that FileUtils.pm's update_file provide --force
3826 support.
3827 * bin/autoheader.in: Pass $force to update_file so that
3828 config.h.in is always recreated when --force.

3832 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
3834 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3836 * doc/autoconf.texi (Limitations of Builtins): Clarify that
3837 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
3839 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3841 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3842 Warn about newline stripping in `` and $(). Update Solaris
3843 version to 9.
3844 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3845 X insulates us from future changes to Posix.
3846 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3847 stripping.
3849 2005-01-19 Stepan Kasal <kasal@ucw.cz>
3851 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

3867 ulongval to be static, to avoid unwanted GCC warning. Problem
3868 reported by Michael Jennings via Daniel Reed; see
3869 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
3871 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3873 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3878 new variables.
3880 2005-01-04 Noah Misch <noah@cs.caltech.edu>
3882 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
3883 not seem to work, assume it does set $(MAKE).

3895 (_m4_divert_n_stack): New macro; the expansion is
3896 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
3897 otherwise.
3898 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3899 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3900 stored in _m4_divert_diversion or _m4_divert_dump.
3901 (m4_divert_pop): When the parameter is given, compare the symbolic
3902 name with the last diversion pushed on the stack. Previously, the
3903 current diversion was compared with the numeric value of the
3904 diversion given as the parameter.
3905 (m4_require): If the macro hasn't been expanded yet, call ...
3906 (_m4_require_call): this new macro.

3939 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

3992 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
3993 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

4120 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):
4121 Don't depend on .x file explicitly, since "make" does that for us.
4122 Suggested by Stepan Kasal.
4124 * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.

4185 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
4187 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
4188 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
4189 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
4190 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
4192 2004-12-07 Stepan Kasal <kasal@ucw.cz>
4194 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

4209 with exactly one parameter.
4211 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4213 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4214 "char c = '\200';" rather than "char c = 0x80;" as the
4215 latter doesn't conform to the strict C standard due to
4216 overflow on signed char hosts.
4218 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4219 to -qlanglvl=ansi. We don't want to disable extensions.

4280 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
4281 the $1_found variable, don't test whether the file is executable;
4282 Both things are checked ...
4283 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
4284 the former ``test -f''.
4285 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
4287 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

4297 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
4299 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed

4320 Problem reported by Stepan Kasal.
4322 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
4324 Fix problems reported by Andreas Buening in:
4325 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html

4331 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4333 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4334 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4335 (trivial change). Problem and patch reported by Andrew Church in:
4336 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4338 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

4365 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4366 texinfo.tex for now (done by hand now).
4367 * Makefile.maint (wget_files, cvs_files):
4368 Remove ansi2knr.c; nobody uses it.
4369 (ansi2knr.c-url_prefix): Remove.
4370 (cvs-update): Fix test for failure. I don't know why it ever
4371 worked...
4373 * doc/autoconf.texi: Update URLs, some of which went stale.
4374 Use @uref rather than @href.
4376 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4377 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4379 * config/config.guess, config/config.sub, config/elisp-comp,
4380 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4381 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4383 * NEWS, TODO, configure.ac, bin/autoscan.in,
4384 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4385 doc/install.texi, lib/Autom4te/Configure_ac.pm,

4389 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4390 tests/tools.at, tests/torture.at:
4391 Use "file name" rather than "filename" or "path",
4392 to be consistent with the terminology of the GNU coding standards.
4394 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4396 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4397 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4398 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4399 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4401 More fixes to support spaces in the name of the build directory.
4402 This isn't a complete fix but it's an improvement.
4404 * bin/autoconf.as (autom4te_options): New var.
4405 Use it instead of appending to AUTOM4TE, so that we can allow
4406 spaces in the build directory's absolute name.
4407 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4408 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

4419 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4421 * doc/autoconf.texi (Function Portability): Document isinf and
4422 and isnan. From a suggestion by Kevin Ryde.
4424 * lib/Autom4te/General.pm (END): Return correct exit status even
4425 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4427 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4429 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4430 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4431 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4433 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4435 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4436 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4437 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4438 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4439 * lib/autom4te.in (Automake-preselections): Preselect
4440 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4442 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4444 * lib/autom4te.in (Automake-preselections): Preselect
4445 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4446 trace them.
4448 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4450 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4451 Tru64.
4452 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4453 Document problem with "`""`" in pdksh POSIX mode.
4455 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4457 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4458 with pdksh, too. Problem reported by Patrick Welche via
4459 Gary V. Vaughan.
4460 * doc/autoconf.texi (Shellology): Note that set -o posix is
4461 useful for pkdsh, too.
4463 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4465 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4466 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4467 Don't fail if ENV or BASH_ENV is readonly.
4468 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4469 etc. are read only. Problem reported by Ludovic Courtes.
4471 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4473 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4474 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4475 (trivial change)
4477 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4479 * doc/autoconf.texi (File System Conventions): Warn about
4480 names like "aux". Problem reported by Eric Blake.
4482 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4483 by zero instead of array size, so that we can use any arithmetic
4484 constant expression (instead of requiring an integer constant
4485 expression). This allows us to test expressions like DBL_MAX <
4486 LDBL_MAX, which didn't conform to the C standard using the old
4487 method.
4488 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4489 now that we can do floating-point tests at compile time.
4491 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4493 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4494 and LDBL_EPSILON, as the resulting expression isn't an
4495 integer constant expression and violates the C standard.
4496 Problem reported by Nelson H. F. Beebe. Also, check
4497 for "L" suffix, and check that long double doesn't have
4498 worse range or precision than double, that mixed-mode
4499 arithmetic doesn't generate a diagnostic, that double
4500 constants fit in long double.
4502 2004-06-03 Kevin Ryde <user42@zip.com.au>
4504 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4505 malloc(0) and realloc(NULL,size).
4507 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4508 Bob Proulx.
4510 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4512 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4513 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4514 by Jim Meyering.
4516 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4518 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4519 can be rewritten using if-then-else. Suggested by Bruno Haible.
4521 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4523 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4524 Problem reported by Stepan Kasal.
4526 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4528 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4529 change). Patch reported by Ralf Wildenhues in
4530 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4532 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4533 function F exists if the compiler and linker let you compile an
4534 expression like (F != 0). Recent versions of GCC optimize away
4535 the reference to F in that case, since every function address must
4536 be nonzero, so the link succeeds even if F does not exist.
4537 Problem reported by Manu in
4538 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4540 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4541 "Unix". Many uses changed.
4542 (Limitations of Builtins): Explain better why the ! command isn't
4543 portable.
4545 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4547 * lib/autom4te.in (Automake-preselections): Preselect
4548 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4550 2004-05-19 Kevin Ryde <user42@zip.com.au>
4552 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4553 referencing AC_FUNC_STRERROR_R.
4555 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4556 note pessimistic assumption when cross compiling.
4558 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4560 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4561 (until 2004) invoked subcommands with sh -e, contra POSIX.
4562 Reported by Kevin Ryde.
4564 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4566 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4567 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4568 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4569 `test -f " /usr/bin/grep"', which _always_ failed.
4570 (AC_PROG_SED): Ditto bogus PATH fix.
4571 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4572 requires that grep correctly supports _multiple_ `-e' options, rather
4573 than stating only that grep should accept `-e'.
4575 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4577 Port to C99, which requires that 'exit' be declared.
4579 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4580 to ensure that stdlib.h is included.
4581 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4582 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4583 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4584 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4585 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4586 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4587 when using 'exit' in a test; C99 requires that 'exit' be declared.
4589 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4591 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4592 now prefers 'grep' implementations that accept -e.
4593 (Limitations of Usual Tools): Describe problems of traditional
4594 egrep and fgrep with long input lines, and of traditional grep
4595 with -e.
4596 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4597 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4598 All callers changed. Append /usr/xpg4/bin to the PATH, for
4599 Solaris.
4600 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4601 the user with complaints about multiple -e options.
4602 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4603 Define it with AC_PROG_GREP.
4604 * configure.ac (AC_PROG_GREP): Add.
4605 * lib/freeze.mk (GREP): New macro.
4607 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4609 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4610 a possible candidate only after all others fail, rather than
4611 consulting it first. This improves backward compatibility by
4612 better reflecting the way shell selection occurred in previous
4613 versions of Autoconf, and should help to avoid triggering latent
4614 problems in other packages, such as the one in Automake where zsh
4615 is not handled robustly:
4616 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4617 Although it is not Autoconf's responsibility to work around
4618 problems in Automake, it nevertheless makes sense to avoid
4619 introducing unnecessary incompatibilites.
4621 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4622 Gary V. Vaughan <gary@gnu.org>
4624 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4625 how deeply nested we are when a suitable tool is found, set the
4626 ac_path_TOOL_found flag.
4627 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4628 nested we are in this macro. Break out of all 3 nested loops if
4629 ac_path_TOOL_found is set.
4631 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4633 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4634 of the _AS_PATH_WALK loop too if GNU flavor is found.
4636 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4638 * doc/autoconf.texi (Limitations of Make): Update documentation
4639 for `$<'. New entry `Long lines', based on a report from Simon
4640 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4641 paragraph about DJGPP, based on a mail from Richard Dawe.
4643 2004-04-20 Paul Eggert <eggert@twinsun.com>
4645 * tests/c.at (C keywords): Don't assume that GCC supports
4646 "restrict" and "inline", as sufficiently-old GCC versions do not
4647 (also, GCC configured to be in pedantic C89 mode does not).
4648 Problem reported by Sumit Pandya in:
4649 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4651 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4652 consider -g to work if it generates warnings when plain compiles
4653 don't. Problem reported by Braden McDaniel in:
4654 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4656 * doc/autoconf.texi (Slashes): New section, to document a problem
4657 reported by Jim Meyering in:
4658 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4660 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4661 linker output files before linking, to work around IRIX 6 linker bug.
4662 Problem reported by Rainer Orth in:
4663 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4665 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4667 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4668 best tool so far counter rely on the tool path variable name to
4669 avoid checks for one tool being affected by the results of running
4670 the length check on a previous tool.
4672 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4673 match expression argument, as different greps have different
4674 regular expression flavours.
4675 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4676 literals.
4677 (AC_PROG_EGREP): Pass 'EGREP$'.
4678 (AC_PROG_GREP): Pass 'GREP$'.
4680 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4682 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4683 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4685 2004-03-29 Paul Eggert <eggert@twinsun.com>
4687 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4688 Types, Specific Compiler Characteristics, System Services,
4689 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4690 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4691 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4692 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4693 Likewise.
4694 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4695 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4696 AC_TYPE_OFF_T): Likewise.
4697 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4698 Likewise.
4700 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
4701 pacify libtool 1.5.2. Fix quoting problems in sed command.
4703 2004-03-28 Paul Eggert <eggert@twinsun.com>
4705 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4706 now defines HAVE_DECL_TZNAME if it is declared, when
4707 HAVE_STRUCT_TM_TM_ZONE is not defined.
4708 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4709 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4710 for HAVE_TZNAME.
4712 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4714 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4715 superfluous backslashing of quotes (") in sed expressions;
4716 thanks to Paul Eggert.
4718 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4720 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4721 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4722 H. F. Beebe for the bug report.
4724 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4726 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4727 quoted -cmdline argument in Portland Group compiler (bug
4728 reported by Jeffrey J. Barteet).
4730 2004-03-25 Kevin Ryde <user42@zip.com.au>
4732 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4733 (Run Time): ... here, where it's now mentioned.

4737 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4738 inherits from language Autoconf-without-aclocal-m4.
4739 (Customizing autom4te): Adjust example; the cache must now be
4740 disabled for language Autoconf-without-aclocal-m4.
4742 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
4743 Nathanael Nerode <neroden@twcny.rr.com>

4753 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
4754 AC_CHECK_TOOLS.
4755 (Specifying Names): Document the reason for these future
4756 behavioral changes.
4757 * tests/mktests.sh: Do not generate tests for the
4758 new macros.
4759 * NEWS: Document these changes.
4761 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4762 they make TeX hang up.

4766 * NEWS: New macro AC_CHECK_ALIGNOF.
4767 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4768 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4769 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4770 vowel.
4771 (AC_CHECK_ALIGNOF): New macro.
4772 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
4773 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
4774 those for sizeof.
4776 2004-03-03 Paul Eggert <eggert@twinsun.com>
4778 * bin/Makefile.am (edit): Don't use $< in a context where
4779 POSIX doesn't require support for it. Use $@.in instead.
4780 Problem reported by Anthony N. Frasso in
4781 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4782 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4784 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4786 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4787 from the next generation of Libtool.
4788 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4790 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4792 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4793 is not always thread-safe. Report from Nathanael Nerode.
4795 2004-02-18 Paul Eggert <eggert@twinsun.com>
4797 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4798 problem on QNX reported by Stephen Rasku in
4799 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4801 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4802 $(m4sh_m4f_dependencies); this removes a FIXME.
4803 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4804 (MAINTAINERCLEANFILES): Split into pieces,
4805 one per related section. Add $(srcdir)/wrapper.in.
4807 2004-02-09 Paul Eggert <eggert@twinsun.com>
4809 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4810 AC_SUBST provides no portable way to escape literal newlines.
4812 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4813 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4814 Darwin uses -lcrt2.o and there's little point to cataloging all
4815 the system variants. Partial fix reported by Andreas Waechter in:
4816 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4817 for bug reported by Nelson H. F. Beebe in:

4820 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
4822 * doc/autoconf.texi (AU_DEFUN): Fix English,
4823 suggested by Paul Eggert.
4824 * lib/autoconf/autoupdate.m4: Correct reference to
4825 acobsolete.m4, suggested by Alexandre Duret-Lutz.
4827 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
4829 * bin/autoupdate.in: Define __file__ so that warnings
4830 refer to the correct file.
4831 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4832 the behavior of the third argument.
4833 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4834 correctly the behavior of the third argument. Document
4835 what the three macros that AU_DEFUN defines do. Fix
4836 warning message when the third argument includes $0
4837 (reported by Alexandre Duret-Lutz).
4839 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4840 Eric Sunshine <sunshine@sunshineco.com>
4841 Paul Eggert <eggert@twinsun.com>
4843 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4844 (AS_INIT): Output shell initialization there. Removed optional
4845 parameter. Expand _AS_SHELL_FN_SPY.
4846 (AS_INIT_WITH_SHELL_FN): Removed.
4847 (_AS_SHELL_FN_SPY): New macro.
4848 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4849 macros.
4850 (AS_SHELL_SANITIZE): Remove loop to find better shell
4851 and documentation for the parameter.
4852 (_AS_DETECT_BETTER_SHELL): Move it here.
4853 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
4854 (_AS_RUN): Move it here, support testing with eval.
4855 (AS_REQUIRE_SHELL_FN): Require shell functions when
4856 it is used.
4857 (_AS_LINENO_WORKS): Put around braces, we do not
4858 trigger the bash bug anymore.
4859 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4860 use AS_INIT_WITH_SHELL_FN.
4861 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4863 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4865 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
4866 * doc/autoconf.texi: Don't say that the third parameter
4867 is broken.
4868 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
4869 (AU_DEFUN): Honor the third parameter, create autoupdate
4870 macros with AU_DEFINE.
4871 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
4872 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

4879 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
4880 * lib/autoconf/status.m4: Remove FIXME.
4881 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
4882 that the macro is not present anymore in the updated
4883 configure.ac.
4884 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
4885 of autoupdate.
4887 2004-01-28 Paul Eggert <eggert@twinsun.com>

4890 copyright years.
4891 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4892 2003 (except 1997) to the list of copyright years. This undoes
4893 the 2003-05-22 change, which removed the older years from the list.
4894 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4896 2004-01-27 Gary V. Vaughan <gary@gnu.org>
4897 Albert Chin-A-Young <china@thewrittenword.com>

4900 grep or ggrep program in PATH that accepts as long lines as
4901 possible.
4902 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4903 AC_PROG_GREP.
4904 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4905 egrep and fgrep respectively if $GREP -E/-F don't work.
4906 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4907 _AC_PROG_GREP, and AC_PROG_SED.
4908 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4909 longest input length accepted by a command.
4910 (AC_PROG_SED): Use it.
4911 * doc/autoconf.texi (Particular Programs): Document the changes.
4912 * NEWS: Updated.
4914 2004-01-27 Paul Eggert <eggert@twinsun.com>
4916 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

4918 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
4919 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
4921 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4922 bin/autoconf.in, config/Makefile.in, config/config.guess,
4923 config/config.sub, config/install-sh, config/mdate-sh,

4936 sources.
4938 2004-01-26 Paul Eggert <eggert@twinsun.com>
4940 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4941 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4942 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4943 not <inttypes.h>. Problem reported by Tim Mooney in
4944 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4945 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4946 Likewise.
4948 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4949 otherwise "make check" fails because it forbids cmp (I guess
4950 because cmp treats files as binary on DOS-like systems).
4952 * tests/mktests.sh: Update copyright date to 2004, since some tests
4953 have changed in 2004.
4955 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4957 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4958 non-truncating sed or gsed program in PATH.
4959 * tests/acprograms.at: Add it.
4960 * doc/autoconf.texi (Particular Programs): Document it.
4961 * NEWS: Updated.
4963 2004-01-15 Paul Eggert <eggert@twinsun.com>
4965 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4966 -std1 disables some useful extensions on Tru64. Problem reported
4967 by N. Lichtmaier in

4972 * doc/autoconf.texi (Programming in M4sh): Document that
4973 AS_MKDIR_P succeeds if the destination is a symbolic link
4974 to an existing directory.
4975 (Limitations of Usual Tools): Note that mkdir -p might not
4976 succeed on symlinks to directories.
4978 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4980 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

4994 2004-01-09 Paul Eggert <eggert@twinsun.com>
4996 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4997 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4998 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4999 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5000 AC_COMPILE_IFELSE, since we now assume our caller invokes
5001 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5002 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5003 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5004 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5006 2004-01-07 Paul Eggert <eggert@twinsun.com>
5008 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5009 `"'...'"`, as it's confusing (and I suspect it may not work on
5010 some platforms). The code was incorrect anyway, as it assumed
5011 that \$ evaluated to itself in that context. Reported by
5012 Alexandre Duret-Lutz.
5014 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

5030 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
5031 autoscan, autoupdate, ifnames): Don't use chmod -w.
5032 * lib/Makefile.am (autom4te.cfg): Likewise.
5033 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
5034 "chmod -w".

5060 srcdir): Likewise.
5061 * doc/autoconf.texi (Limitations of Usual Tools):
5062 Warn against "rm -fr".
5064 2004-01-03 Paul Eggert <eggert@twinsun.com>
5066 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5067 -c -o might not work. From a suggestion by Kevin Ryde.
5068 (C Compiler, Generating Sources, Limitations
5069 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5070 Don't put '-o' after non-options, as POSIX doesn't allow this.
5071 Mention that cc's name might be gcc or c89 or whatever.
5073 2004-01-04 Kevin Ryde <user42@zip.com.au>
5075 * doc/autoconf.texi: Add various further index entries.
5077 2003-12-29 Paul Eggert <eggert@twinsun.com>
5079 * bin/autoreconf.in (autoreconf_current_directory):

5082 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
5084 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
5085 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

5123 _AS_LINENO_WORKS, use it to find out if shell
5124 functions work.
5125 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
5126 does not work.
5127 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

5142 them on the fly.
5144 2003-11-24 Akim Demaille <akim@epita.fr>
5146 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

5397 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5398 cache variable instead of $G77 to decide whether to include -O2,

5457 * config/announce-gen (&print_news_deltas): Extracted from...
5458 (&print_changelog_deltas): here.
5459 (&news_file): Rename as...
5460 (@news_file): this.
5462 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
5464 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
5465 have been created when invoking the compiler.

5477 Problem reported by Lars J. Aas in
5478 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
5479 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5480 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5481 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5483 2003-09-26 Akim Demaille <akim@epita.fr>
5485 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5486 directory for AC_CONFIG_COMMANDS' first argument exists.
5487 This makes valid the invocation of _AC_SRCPATH that follows.
5488 Reported by Eric Sunshine.
5489 * doc/autoconf.texi (Configuration Commands): Adjust.
5491 2003-09-26 Akim Demaille <akim@epita.fr>
5493 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5494 Reported by Ralf Corsepius.
5496 2003-09-26 Akim Demaille <akim@epita.fr>
5498 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5499 arguments.
5500 Actually, use AU_ALIAS.
5501 From Bruno Haible.
5503 2003-09-26 Paul Eggert <eggert@twinsun.com>
5505 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,

5512 The test suite are sometimes assigning timings incorrectly.
5513 Reported by Henk Krus.
5514 Diagnosed by Nicolas Joly.
5516 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5517 AT_help_all.
5518 Instead of making AT_help a sequence of assignments to grow
5519 $at_help_all, just make AT_help_all be the growing contents of
5520 $at_help_all, and make a single assignment in...
5521 (AT_INIT): here.
5522 (at_times_skip): Flip the meaning and rename as...
5523 (at_times_p): this.
5524 (AT_INIT): When summarizing the test that ran, remove
5525 $at_times_file after use, and check it is present before trying to
5526 use it.
5528 2003-09-25 Akim Demaille <akim@epita.fr>
5530 Version 2.57d.
5532 * bin/Makefile.am (edit): Handle '@configure_input@'.
5533 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5534 (ifnames): chmod -w.
5535 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5536 executables, not bin/ executables! Otherwise all the magic needed
5537 to find non installed files is turned off. This caused a failure
5538 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5539 as found in its environment (sent by tests/autoreconf): pointing
5540 to bin/autom4te that could not find its files.
5541 * tests/mktests.sh: Force the replacement of generated files, for
5542 the sake of "mv" program that are interactive when overwriting a
5543 -w file.
5544 * config/install-sh: Upgrade from CVS Automake.
5546 2003-09-23 Paul Eggert <eggert@twinsun.com>
5548 * doc/autoconf.texi (Limitations of Builtins): Document test -h
5549 versus test -L issues.
5551 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
5552 Paul Eggert <eggert@twinsun.com>
5554 Trivial change to support GCC's configuration procedure.
5555 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5556 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5557 about inconsistency if the preprocessor is set to give errors for
5558 any warning.

5575 from masters.
5577 2003-09-12 Akim Demaille <akim@epita.fr>
5579 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5580 not asm/types.h.
5582 2003-09-11 Akim Demaille <akim@epita.fr>
5584 * doc/autoconf.texi (Header Portability): linux/random.h.
5585 From Peter Hendrickson.
5587 2003-09-10 Akim Demaille <akim@epita.fr>
5589 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5590 willing to edit the output files.
5592 2003-09-10 Akim Demaille <akim@epita.fr>
5594 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5595 and AC_FC_FREEFORM.
5596 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5597 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
5599 2003-09-09 Akim Demaille <akim@epita.fr>
5601 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.

5612 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
5613 Improve the accuracy of the wording about obsolescence.
5614 From a suggestion by Ian Lance Taylor in
5615 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5617 2003-09-05 Paul Eggert <eggert@twinsun.com>
5619 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5620 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5622 2003-09-04 Akim Demaille <akim@epita.fr>
5624 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5625 AC_FUNC_WAIT3.
5627 2003-09-04 Akim Demaille <akim@epita.fr>
5629 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5630 (freeze): When exiting, use $exit_code.
5631 * lib/autoconf/fortran.m4: Comment changes.
5633 2003-09-04 Akim Demaille <akim@epita.fr>

5637 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5639 Add support for newer Fortran dialects. The F77 interface is
5640 unchanged, and continues to support Fortran 77. New FC macros
5641 correspond to all the old F77 macros, with output variables FC,
5642 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5643 available dialect, but older dialects can be specified. There are
5644 new macros AC_FC_SRCEXT to set the source extension, and
5645 AC_FC_FREEFORM to accept free-form source files.
5647 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5648 New macros.
5649 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

5664 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
5665 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5666 Rewrite in terms of the above.
5667 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5668 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
5669 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
5670 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.

5674 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5675 Document problems with timestamp resolution that 'make', 'cp -p', and
5676 'touch -r' have.
5678 2003-08-27 Akim Demaille <akim@epita.fr>
5680 * tests/m4sugar.at (cross_warning): Make sure to enable the
5681 output, so that we can track spurious m4sugar output.
5682 * tests/local.at: Require 2.57.
5683 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5684 are defaulted by AT_CHECK anyway.
5685 Use AT_CHECK_AUTOM4TE.
5686 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5687 missing dnl.
5689 2003-08-27 Akim Demaille <akim@epita.fr>
5691 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5692 when -Wobsolete is set.
5693 Set it on by default.
5694 Suggested by Klee Dienes.

5745 * bin/autom4te.in: Adjust to output the call stack.
5746 * tests/m4sugar.at (m4@&t@_warn): Adjust.
5748 2003-08-22 Akim Demaille <akim@epita.fr>
5750 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.

5755 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
5756 (&verbose): Remove.

5771 2003-08-21 Akim Demaille <akim@epita.fr>
5773 First stab at preserving warnings between calls to autom4te,
5774 including when the cache is used.
5776 There are still several issues: (i) there are too many runs of m4
5777 (one for include, one for warnings, and some more), (ii) warnings
5778 spreading on several lines are not handled gracefully, (iii) the
5779 code meant to have the call stack display for errors does not work
5780 (its handling should move from m4 to autom4te).
5782 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5783 Use them.
5784 (@preselect): Add m4_warn.
5785 ($exit_status): Remove, use $exit_code.
5786 ($help): Use Autom4te::ChannelDefs::usage.
5787 (&handle_m4): No longer define the m4_warnings.
5788 At each run, extract and report the warnings.
5789 Always cache the result, including if the exit status is on
5790 failure, since if nothing changes, we should result in the same
5791 failure, hence we can use the cache.
5792 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5793 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5794 Remove.
5795 (m4_warn): Redefine as a do-nothing: it is its invocation that
5796 matters, as warnings are now reported via traces.
5797 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5798 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5799 the latter reveals calls to the former.
5801 Adjust the tests.
5803 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5805 2003-08-21 Akim Demaille <akim@epita.fr>
5807 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5808 Use them.

5812 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5813 forward order.
5814 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5815 (&parse_warnings): Accept a list of warning requests.
5816 (&usage): Return a string, not a side effect.
5817 (cross): New warning category.
5819 2003-08-21 Akim Demaille <akim@epita.fr>
5821 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5822 (&require_configure_ac): Accept an optional directory argument.
5823 ($configure_ac): Remove.
5824 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5825 (&catfile): Remove.
5826 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5827 * bin/autoscan.in: Adjust.
5829 2003-08-20 Akim Demaille <akim@epita.fr>
5831 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5832 Reported by Alexandre Duret-Lutz.
5834 2003-08-20 Akim Demaille <akim@epita.fr>
5836 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5837 * bin/autom4te: Adjust.
5838 In particular, be Autoconf tools are really silent when properly
5839 working, bind the verbosity of the 'note' channel to $verbose.
5840 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5841 (&xsystem, &contents): Remove, since they are exported by...
5842 * lib/Autom4te/FileUtils.pm: this.
5843 More perldoc.
5844 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5845 * lib/Autom4te/FileUtils.pm: here.
5847 2003-08-20 Akim Demaille <akim@epita.fr>
5849 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5850 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

5902 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5903 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5904 shorter column three. Add DESCRIPTION to log file content.
5906 2003-08-13 Derek Price <derek@ximbiot.com>
5908 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

5930 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
5931 -lcrt1.o, for OS X. (trivial change)
5933 2003-07-07 Paul Eggert <eggert@twinsun.com>
5935 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
5936 inside '#ifndef __cplusplus'. Problem reported by
5937 Bob Friesenhahn.
5939 2003-07-06 Bill Clarke <llib@computer.org>
5941 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5942 'long', not 'int', for benefit of Sun's recent C++ compilers
5943 (trivial change). See:
5944 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5945 (This really should be 'intptr_t', not 'long', but that would
5946 take more work.)
5948 2003-06-25 Akim Demaille <akim@epita.fr>
5950 * lib/Makefile.am (autom4te.cfg): Make it read only.
5951 Depend on Makefile since it contains substitutions.
5952 From Paolo Bonzini.
5953 * lib/autom4te.in (args): Add local.at? for Autotest args.
5954 This change was made on autom4te.cfg which is generated.
5955 Reported by Raja R. Harinath.
5957 2003-06-25 Akim Demaille <akim@epita.fr>
5959 * doc/autoconf.texi (Header Portability): sys/mount.h.
5960 From Gareth McCaughan.
5962 2003-06-23 Akim Demaille <akim@epita.fr>
5964 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5965 not all of them. This fixes 1. the fact that when testing
5966 Autoconf there are many many config.log, 2. the incorrect use of
5967 top_srcdir to find config.log.
5968 Don't mix the detailed output of failed test with the summary of
5969 failures. Rather, append detailed log afterwards.
5971 2003-06-23 Akim Demaille <akim@epita.fr>
5973 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5974 always run: output config.log on $at_group_log.
5976 2003-06-23 Akim Demaille <akim@epita.fr>
5978 * tests/torture.at (#define header templates): Don't use quotes in
5979 C++ comments as it puzzles Emacs' sh font-lock-mode.
5981 2003-06-23 Akim Demaille <akim@epita.fr>
5983 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5984 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5985 * tests/atspecific.m4: Rename as...
5986 * tests/local.at: This.
5987 * tests/suite.at: Move the globals into...
5988 * tests/local.at: here.
5989 * tests/Makefile.am: Adjust.
5990 * doc/autoconf.texi (testsuite Scripts): Adjust.
5992 2003-06-21 Kevin Ryde <user42@zip.com.au>
5994 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5995 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5996 ensuring we add -std1 for full-ANSI.
5998 * doc/autoconf.texi (hdrindex): New macro.
5999 Add index entries for portability of various standard header files.
6001 2003-06-20 Akim Demaille <akim@epita.fr>
6003 * configure.ac: Bump to 2.57b.
6005 2003-06-20 Akim Demaille <akim@epita.fr>
6007 Version 2.57a.
6009 2003-06-20 Akim Demaille <akim@epita.fr>
6011 * bin/autom4te.in: Don't rely on $HOME being defined.
6012 Reported by Marc Espie as PR/233.
6014 2003-06-20 Akim Demaille <akim@epita.fr>
6016 * lib/autotest/general.m4: Use at_times_file only if used.
6017 From Nicolas Joly.
6019 2003-06-20 Akim Demaille <akim@epita.fr>
6021 * config/config.guess, config/config.sub, config/elisp-comp,
6022 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
6023 Update from masters.
6025 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6027 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6028 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6029 (TEST_SCRIPT): New diversion.
6030 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6031 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6032 (AT_INIT): Support for expected failures.
6034 2003-06-02 Akim Demaille <akim@epita.fr>
6036 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6037 changes.
6038 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6039 Autoconf nor Automake.
6040 (&contents): New, from Automake.
6041 PODify.
6043 2003-05-28 Paul Eggert <eggert@twinsun.com>
6045 * NEWS, doc/autoconf.texi (Particular Functions),
6046 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6047 is the inverse of localtime.
6049 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6051 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6052 (handle_exec_errors): New function. Work around $! being
6053 altered by WEXITSTATUS.
6054 (xqx, xsystem): Use handle_exec_errors.
6056 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6058 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6059 Do not call `_exit()', simply modify `$?'.
6060 (xsystem): Reset $! before running system, and check it afterward.
6061 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6062 63 for version mismatches.
6064 2003-05-23 Akim Demaille <akim@epita.fr>
6066 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6067 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6068 the middle of a line).
6069 * lib/m4sugar/m4sugar.m4: Likewise.
6070 Remove useless spaces in comments.
6072 2003-05-23 Akim Demaille <akim@epita.fr>
6074 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6075 exit 63, so that we (or Automake's "missing") can tell the
6076 difference with a plain failure.
6077 * doc/autoconf.texi (Notices): Adjust.
6079 2003-05-23 Akim Demaille <akim@epita.fr>
6081 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6082 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6083 White spaces cleanup.
6085 2003-05-22 Jim Meyering <jim@meyering.net>
6086 Paul Eggert <eggert@twinsun.com>
6088 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6089 Remove `#include <stdlib.h>' from the list; we should never
6090 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6091 resulting namespace pollution would cause other tests to fail.
6092 Configure scripts run with some older versions of g++ and HP's
6093 aCC would fail due to such an #include. Problems reported by
6094 Matthew Mueller in <http://bugs.debian.org/120704> and by
6095 Keith Bostic in
6096 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6097 In the test, use the test declaration before including <stdlib.h>,
6098 as that's closer to how it'll be used.
6100 2003-05-23 Akim Demaille <akim@epita.fr>
6102 * doc/autoconf.texi (Header Portability): ucred.h.
6103 From Ian Redfern.
6105 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6107 Overhaul Autotest's logging: generate separate log files
6108 in testsuite.dir/NNN/testsuite.log, and append them to
6109 testsuite.log instead of re-running the test verbosely.
6111 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6112 file descriptor, write 0 to at_status_file instead of setting
6113 at_status=0, initialize some new variables (at_status_file,
6114 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6115 to rerun the tests, instead append the at_group_log to the
6116 at_suite_log when a test fails.
6117 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6118 with the AS_MESSAGE_LOG_FD redirected to stdout.
6119 (AT_CLEANUP): save the output status in $at_status_file
6120 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6121 its original place.
6122 (AT_CHECK): since tests are run with a redirected stdout,
6123 and used to be re-run in verbose mode, turn some $at_verbose
6124 into echo, and don't redirect the output of testing stdout
6125 and stderr.
6127 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6128 the name of the debugging directory and information about
6129 its contents.
6131 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6133 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6134 parameter.
6136 2003-05-22 Akim Demaille <akim@epita.fr>
6138 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
6139 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
6140 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4
6141 * lib/autoconf/status.m4: Fix and adjust copyright notices.
6143 2003-05-22 Akim Demaille <akim@epita.fr>
6145 * aclocal.m4, bin/autoconf.as, lib/autoconf/autoconf.m4,

6156 Whitespace clean up.
6157 Suggested by Jim Meyering.
6159 2003-05-22 Akim Demaille <akim@epita.fr>
6161 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
6162 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
6163 Reported by Jim Meyering.
6165 2003-05-22 Akim Demaille <akim@epita.fr>
6167 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.
6168 Add AC_HELP_STRING to the obsolete macros section.
6169 Typos.
6170 Use '@.' for sentences that ended in a capital letter.
6171 From Art Haas.
6173 2003-05-22 Akim Demaille <akim@epita.fr>
6175 * config/config.guess, config/config.sub, config/elisp-comp,

6182 it to eval.
6184 2003-05-21 Akim Demaille <akim@epita.fr>
6186 * bin/autoupdate.in ($m4): Fix quotation.
6187 Reported by Martin Mokrejs.
6189 2003-05-19 Paul Eggert <eggert@twinsun.com>
6191 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:

6197 * tests/semantics.at (AC_CHECK_HEADERS_OLD,
6198 AC_CHECK_HEADERS_NEW): New tests.
6200 2003-05-17 Akim Demaille <akim@epita.fr>
6202 * lib/autoconf/functions.m4: Use the default includes so that
6203 memcmp be declared before being tested.
6204 Reported by Sander Niemeijer.
6205 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
6206 * doc/autoconf.texi (Default Includes): Document
6207 AC_INCLUDES_DEFAULT.
6209 2003-05-17 Akim Demaille <akim@epita.fr>
6211 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
6212 * doc/autoconf.texi (Obsolete Macros): Adjust.
6213 Reported by Werner LEMBERG and Debian Bug 190886.
6215 2003-05-16 Akim Demaille <akim@epita.fr>
6217 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
6218 user name space clashes.
6219 Reported by Bruno Haible.
6221 2003-05-16 Akim Demaille <akim@epita.fr>
6223 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6224 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
6225 them uniform, and more robust to Perl special characters.
6226 Reported by Martin Mokrejs.
6228 2003-05-14 Akim Demaille <akim@epita.fr>
6230 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
6232 2003-05-14 Akim Demaille <akim@epita.fr>
6234 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,
6235 linux/irda.h.

6239 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
6240 message.
6241 From Matthias Andree.
6243 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
6245 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
6246 and truncate.
6248 2003-05-06 Akim Demaille <akim@epita.fr>
6250 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6251 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6252 by aclocal.m4 is changed it might require the importing of another
6253 m4 extension file, i.e., aclocal must be run.
6255 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6256 (&parse_args): Use --force with aclocal if required and supported.
6257 (&autoreconf_current_directory): Use &run_aclocal.
6259 2003-05-06 Akim Demaille <akim@epita.fr>
6261 Lock autom4te's cache.
6263 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
6264 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6265 argument instead of a file name, so that the request file remains
6266 open during the whole autom4te run.
6267 ($icache_file): New.
6268 (&freeze): Lock the $icache_file.
6270 2003-04-29 Derek Price <derek@ximbiot.com>
6272 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6273 seperator with m4_append_uniq(). It doesn't work.
6274 (AT_CLEANUP): Add `;' to end of at_help_all.
6275 (AT_INIT): Allow --keywords to be specified more than once. When
6276 grepping $at_help_all for keywords, use the field and keyword
6277 seperators to ensure a complete keyword match. Alter at_prev handling
6278 to support the new --keywords behavior.
6280 2003-04-27 Karl Berry <karl@freefriends.org>
6282 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6283 align better with others. I also made some of the individual
6284 entries on one line, for brevity and to make it easier for me to
6285 sort my dir-example file in the Texinfo distribution :).
6287 2003-04-12 Jim Meyering <jim@meyering.net>
6289 * NEWS: Mention the new macro.
6290 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.
6291 * doc/autoconf.texi (C Compiler): Describe AC_C_RESTRICT.
6292 * tests/c.at: Test AC_C_RESTRICT.

6295 2003-04-08 Akim Demaille <akim@epita.fr>
6297 * bin/ifnames.in: Skip C++ comments.
6298 From Jeremy Yallop.
6300 2003-04-08 Akim Demaille <akim@epita.fr>
6302 * GNUmakefile (SHELL): Don't assume sh is in /bin/.
6303 From Ilya Zakharevich.
6305 2003-04-08 Akim Demaille <akim@epita.fr>
6307 * doc/autoconf.texi (Particular Headers): Some about sys/socket.h,
6308 net/if.h, stdlib.h.
6310 2003-04-01 Derek Price <derek@ximbiot.com>
6312 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Correct syntax error
6313 from Akim's checkin of 2003-03-29.
6315 2003-04-01 Derek Price <derek@ximbiot.com>
6317 * tests/torture.at (Configuring subdirectories): Add missing
6318 close-quote for Akim's change from 2003-03-28.
6320 2003-04-01 Akim Demaille <akim@epita.fr>
6322 * doc/autoconf.texi (ac, at, ms): Rename these indexes as...
6323 (AC, AT, MS): these.
6324 (shortindexflag, @acindex, @ahindex, @asindex, @atindex, @msindex):
6325 New.
6326 Use them.
6327 * doc/Makefile.am (CLEANFILES): Adjust.
6328 (TEXI2DVI): Make it --batch.
6330 2003-03-31 Derek Price <derek@ximbiot.com>
6332 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
6333 which removed the main loop.
6334 Thanks to Akim Demaille.
6336 2003-03-29 Akim Demaille <akim@epita.fr>
6338 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
6339 that starts a GUI.
6340 From Ilya Zakharevich.
6342 2003-03-29 Akim Demaille <akim@epita.fr>
6344 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
6345 documentation to read is Autoconf's.
6346 Suggested by Paul Eggert.
6348 2003-03-28 Akim Demaille <akim@epita.fr>
6350 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
6351 reading the section "Present But Cannot Be Compiled" when the
6352 header causes problems.
6354 2003-03-28 Akim Demaille <akim@epita.fr>
6356 * tests/torture.at (Configuring subdirectories): Require aclocal
6357 1.4, otherwise the test fails, as it does support configure.ac.
6358 This fixes the "test 40 failed" bug reports.
6360 2003-03-28 Akim Demaille <akim@epita.fr>
6362 * doc/autoconf.texi (C Compiler): `#line' portability.
6363 From Paul Eggert and Nelson H. F. Beebe.
6365 2003-03-27 Derek Price <derek@ximbiot.com>
6367 * lib/autotest/general.m4: Eliminate main loop and reorganize test
6368 layout in order to allow scripting around test groups.
6370 2003-03-27 Derek Price <derek@ximbiot.com>
6372 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
6373 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
6374 use new diversions in preparation for accepting new arguments and
6375 allowing scripting around tests.
6376 (OPTIONS,TAIL): Remove these diversions to make way for the ones above.
6378 2003-03-26 Derek Price <derek@ximbiot.com>
6380 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of

6386 * tests/acgeneral.at: Regenerated.
6388 2003-03-26 Derek Price <derek@ximbiot.com>
6390 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
6391 sense. Verbosify the diversion definitions comment.
6393 2003-03-26 Derek Price <derek@ximbiot.com>
6395 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
6396 AS_PREPARE.
6398 2003-03-21 Eric Siegerman <eric_97@pobox.com>
6400 * doc/autoconf.texi (Present But Cannot Be Compiled):
6401 Grammar fixes and minor rewording. (trivial change)
6403 2003-03-06 Paul Eggert <eggert@twinsun.com>
6405 Work around a problem noted by Nelson H. F. Beebe with coreutils
6406 4.5.9: Sun c89 (Sun WorkShop 6 update 2 C 5.3 Patch 111679-08
6407 2002/05/09) rejects '#line 32768 "configure"' because the line
6408 number overflows.
6409 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Do not generate
6410 #line directives.

6428 about `$<' in inference rules, it was a bogus interpretation of
6429 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
6430 Tru64 make in the "target lookup" section.
6431 (Automake): Automake 1.5+ no longer requires special tools to be
6432 present on the developer's host.
6434 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
6436 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
6437 to a shell that can handle redirection or quoting correctly.

6448 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
6449 to cope with DOS-style absolute paths, when constructing
6450 ${ac_make}.
6452 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6453 When constructing paths with IFS=:, quote the path. If we're
6454 constructing a DOS-style absolute path, we don't want to split it
6455 on the colon.
6457 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
6458 in description.
6460 2003-02-25 Pavel Roskin <proski@gnu.org>

6472 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
6473 to fix a mismatch between example and discussion.
6475 2003-02-24 Kevin Ryde <user42@zip.com.au>
6477 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6478 format starting with "-".
6480 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6482 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6483 is not portable inside Makefile.
6485 2003-02-20 Akim Demaille <akim@epita.fr>
6487 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6488 compiler says yeah, but preproc says nope, compiler is right.
6489 Conversely, prompt the reader to send a bug report to the
6490 maintainers of the package, not of Autoconf.
6492 2003-02-20 Klee Dienes <kdienes@apple.com>
6494 * bin/autoreconf.in (autoreconf_current_directory): Properly

6505 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6506 innocuous variant befor including <limits.h> or <assert.h>. This
6507 works around a bug reported by Albert Chin: HP-UX 11i
6508 (and earlier versions) have a <limits.h> that declares
6509 gettimeofday and many other functions.
6511 2002-12-03 Paul Eggert <eggert@twinsun.com>
6513 Version 2.57.
6515 * NEWS, configure.ac: Update version.
6517 * doc/fdl.texi: Upgrade to FDL version 1.2.
6519 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6520 nontrivially in main's body, so that f's external declaration is
6521 not optimized away in AIX. This should fix the bug reported by
6522 Martin Frydl in
6523 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6525 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6526 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6527 defined, to support freestanding compilers. This should fix the
6528 bug reported by Momchil Velkov in
6529 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6531 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6532 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

6537 * Makefile.maint (www-gnu): New macro.
6538 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6539 the location has moved.
6541 2002-12-02 Martin Frydl <martin@systinet.com>
6543 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6544 \(.*\) match is too long and there is something more to be checked.
6545 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
6547 2002-11-15 Akim Demaille <akim@epita.fr>

6554 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
6555 * configure.ac (AM_INIT_AUTOMAKE): here.
6556 Require 1.7.1.
6558 2002-11-14 Akim Demaille <akim@epita.fr>
6560 Version 2.55.
6562 * config/config.guess, config/config.sub, config/install-sh:
6563 Update from masters.
6565 2002-11-14 Akim Demaille <akim@epita.fr>
6567 * Makefile.maint: Sync with Bison, i.e.:
6568 (po-check): Scan .l and .y files instead of the
6569 .c and the .h files that they generate. This fixes the bug
6570 reported by Tim Van Holder in:
6571 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6572 Look for N_ as well as for _. Try to avoid matching #define for
6573 N_ and _.
6574 From Paul Eggert.
6576 2002-11-14 Akim Demaille <akim@epita.fr>
6578 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6579 From Paul Eggert and Albert Chin-A-Young.
6581 2002-11-14 Akim Demaille <akim@epita.fr>
6583 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6584 From Paul Eggert and Albert Chin-A-Young.
6586 2002-11-14 Kevin Ryde <user42@zip.com.au>
6588 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6589 than assigning in main, to avoid HP cc +O3 optimizing it away.
6591 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6593 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6594 option. Process --recheck after parsing all options. Pass -q
6595 option to configure on --recheck.
6596 (AC_OUTPUT): Pass -q from configure to config.status.
6597 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6598 arguments to record.
6599 * doc/autoconf.texi (config.status Invocation): Document
6600 config.status -q option.
6602 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

6605 Makefile.in if Makefile.am exists.

6616 2002-11-06 Akim Demaille <akim@epita.fr>
6618 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
6619 declaration in extern "C" too.

6624 * tests/torture.at (Configuring subdirectories): Don't use grep
6625 -w.
6626 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
6627 Reported by Ezra Peisach.
6629 2002-11-05 Akim Demaille <akim@epita.fr>
6631 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6632 Remove.
6633 We _have_ to stop using the old compatibility scheme that tried to
6634 avoid useless backslashes because Libtool 1.4.3 contains a
6635 AC_DEFINE([error_t], [int],
6636 [Define to a type to use for \`error_t' if it is not
6637 otherwise available.])
6638 We _have_ to quote the single quote and backslashes with \. The
6639 old compatibility scheme saw that ` was backslashed, and therefore
6640 did not quote the single quote. Hence before this patch, Autoconf
6641 was not compatible with Libtool.
6643 2002-11-04 Paul Eggert <eggert@twinsun.com>
6645 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6650 2002-11-04 Akim Demaille <akim@epita.fr>
6652 Version 2.54c.
6654 * Makefile.maint (update, cvs-update, po-update, do-po-update):

6660 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
6661 from...
6662 (&autoreconf): here.
6663 ($help, $make, &parse_args, &autoreconf_current_directory):
6664 Support -m/--make.
6665 * doc/autoconf.texi (autoreconf Invocation): Adjust.

6681 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
6683 2002-10-31 Akim Demaille <akim@epita.fr>
6685 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6686 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6687 Make variable, not a shell variable.
6688 Suggested by Bruno Haible.
6690 2002-10-31 Akim Demaille <akim@epita.fr>
6692 * bin/autom4te.in (load_configuration): Reject #args out of any
6693 language.
6695 2002-10-31 Akim Demaille <akim@epita.fr>
6697 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

6709 Suggested by Tim van Holder.
6711 2002-10-29 Paul Eggert <eggert@twinsun.com>
6713 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
6714 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
6715 Problem reported by Bruno Haible.
6717 2002-10-29 Akim Demaille <akim@epita.fr>
6719 * doc/autoconf.texi (Header Templates): Put also in words what the
6720 pictures says to assist free style readers.
6721 (Customizing autom4te): s/--cache=/--cache /.
6723 2002-10-29 Akim Demaille <akim@epita.fr>
6725 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
6726 sys/wait.h.
6727 sparc_address_test returns void.
6728 Use it with an argument, as prototyped.
6729 From Bruno Haible.
6731 2002-10-29 Akim Demaille <akim@epita.fr>

6739 * tests/torture.at (Deep Package): New test.

6745 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
6746 * doc/autoconf.texi (Invoking autom4te): Rename as...

6951 `$ac_configure_args'.

6973 2002-10-22 Akim Demaille <akim@epita.fr>
6975 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
6976 are a few warnings.
6977 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
6978 Quote for Perl '' strings, not "".
6979 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
6980 strings.
6982 2002-10-22 Akim Demaille <akim@epita.fr>
6984 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
6985 characters is a syntax warning now.

6987 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):

6992 `@', to tickle Perl's lists.
6993 Reported by Carlos Velasco.
6995 2002-10-18 Akim Demaille <akim@epita.fr>
6997 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that

7007 2002-10-17 Akim Demaille <akim@epita.fr>
7009 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
7010 Fixes the `AC_ARG_VAR' test failures.

7030 Because of caching, some files that no longer exist and are no
7031 longer required can still cause errors.
7032 Reported by Alexandre Duret-Lutz.
7034 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7035 to frozen files in @ARGV, as @ARGV must remain being a list of
7036 files. Rather, at M4 call sites, use this...
7037 (&files_to_options): New function.
7038 (&freeze): Use &error.
7039 (&up_to_date): If a file that was included according to the cache
7040 is no longer there, then the output is out dated.
7041 (&main): Don't even check whether a file is up to date is anyway
7042 --force is given.
7043 * tests/tools.at (autom4te cache): New.
7045 2002-10-16 Akim Demaille <akim@epita.fr>
7047 * bin/autoconf.as: Kill dead options.
7048 * bin/autoupdate.in (&parse_args): Kill old options.
7049 * bin/autoreconf.in (&parse_args): Remove dead options.
7050 Factor some code.
7051 (&autoreconf): Report the directories we enter *and leave*, so
7052 that error messages can be easily located, and use GNU Make
7053 format, so that Emacs' compile mode understands us.
7054 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7055 if some file was changed instead of `print'.
7056 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
7057 (&parse_args): Remove the dead options.
7058 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new

7069 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)

7089 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
7090 file name to enable parallel executions.
7091 From Sam Varshavchik.
7093 2002-10-08 Akim Demaille <akim@epita.fr>
7095 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7096 aclocal invocation, as Gettext macros might not be visible to
7097 aclocal.
7098 Instead of blindly running autopoint, scan configure.ac (not the
7099 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7100 Reported by Paul D. Smith.
7102 2002-10-08 Paul Eggert <eggert@twinsun.com>
7104 Work around problems found when POSIXLY_CORRECT=1 is set.
7105 None of this seems to have anything to do with POSIX, really,
7106 but it's how Perl getopt works.
7107 * bin/autom4te.in (parse_args): Configure GetOpt with
7108 "permute", too.
7109 * doc/autoconf.texi (Invoking autom4te):
7110 --warning -> --warnings.
7111 * lib/autom4te.in: --warning -> --warnings.

7130 2002-09-28 Akim Demaille <akim@epita.fr>
7132 * tests/torture.at (Configuring subdirectories): Be robust to
7133 users who use config.site to require for a cache: in this case,
7134 the two last configure runs, using two different sets of
7135 arguments, trigger a legitimate error.
7137 2002-09-28 Akim Demaille <akim@epita.fr>
7139 * tests/m4sh.at (Functions Support, Functions and return Support):
7140 New.

7153 (tm_zone): Move their rules to...
7154 * lib/autoconf/types.m4: here, using AN_ macros.
7155 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7156 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7157 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7158 * lib/autoconf/programs.m4: here.

7170 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7171 (.m4.m4f): Don't pass --prepend-include, since that's done by
7172 tests/autom4te itself.
7173 * lib/autoscan/Makefile.am: Include freeze.mk.
7174 (autoscan.list): New target --this file is no longer a source.
7175 (autoscan.pre): New file.
7177 2002-09-28 Akim Demaille <akim@epita.fr>
7179 * bin/autoscan.in (@kinds): Make them singular.
7180 Adjust all uses.
7181 (&init_tables): When --debug, report the list of rules to ease
7182 tracking changes in autoscan.list.
7183 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7185 2002-09-28 Akim Demaille <akim@epita.fr>

7196 * lib/autoscan/identifiers, lib/autoscan/makevars,
7197 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7198 `functions' line is now prefixed with `function:'.
7199 * bin/autoscan.in (&init_tables): Adjust.
7201 2002-09-28 Akim Demaille <akim@epita.fr>
7203 From now on, autoscan files must always map a macro name to a
7204 word: there is no `default' macro for autoscan.
7206 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7207 all.
7208 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7209 explicit.
7211 2002-09-28 Akim Demaille <akim@epita.fr>
7213 * bin/autoscan.in (%c_keywords): Remove.
7214 (&used): Keep only track of the words we might be interested in.
7215 (&output_kind): It is no longer needed to look for non active
7216 checks.

7245 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7246 Reported by Ralf Corsepius.
7247 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7249 2002-09-26 Akim Demaille <akim@epita.fr>
7251 Single suffix rules and seperated dependencies are not portable.
7253 * doc/autoconf.texi (Installation Directory Variables): Update.
7254 (Limitations of Make): Some about `Single Suffix Rules and

7269 * bin/Makefile.am (SUFFIXES, .in): Remove.
7270 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):

7273 2002-09-16 Akim Demaille <akim@epita.fr>
7275 i960 compilers create `b.out' files by default.
7276 Reported by Ralf Corsepius.
7278 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.

7297 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest

7299 Suggested by Guido Draheim.
7301 2002-09-13 Akim Demaille <akim@epita.fr>
7303 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7304 (chdir_init) might hang when stat'ing mounted directories.

7307 2002-09-12 Akim Demaille <akim@epita.fr>
7309 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7310 the lists.
7312 2002-09-12 Akim Demaille <akim@epita.fr>
7314 * doc/autoconf.texi (Defining Symbols): Present two different
7315 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

7320 * doc/autoconf.texi: Review grammar and punctuation.

7325 grammatical typos.
7326 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7327 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7328 is obsolescent.
7330 2002-09-11 Akim Demaille <akim@epita.fr>
7332 * doc/autoconf.texi (Questions): Rename as...
7333 (FAQ): this.

7348 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7349 `duplicates', since the algorithm was too naive and could keep
7350 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7351 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7352 Reported by Ralf Corsepius.
7353 * tests/torture.at (Configuring subdirectories): Exercise these
7354 cases.
7356 2002-09-09 Akim Demaille <akim@epita.fr>

7359 looking for a replacement file.
7360 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7361 directory is relative.
7362 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7363 directory definition.
7364 Reported by Andreas Schwab and Jim Meyering.
7366 2002-09-06 Akim Demaille <akim@epita.fr>

7369 precious variables are.
7370 Suggested by Pontus Skoeld.
7372 2002-09-05 Akim Demaille <akim@epita.fr>
7374 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7375 (ifnames, autoscan, autom4te): Since we don't only depend on
7376 configure.ac variables (such as VERSION etc.), but also on prefix
7377 and so forth, depend on Makefile, not configure.ac.
7378 Reported by Alexandre Duret-Lutz.
7379 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7381 2002-09-05 Kevin Ryde <user42@zip.com.au>
7383 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7384 doesn't seem to be confined to ia64, just say "some versions".
7386 2002-09-04 Akim Demaille <akim@epita.fr>
7388 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by

7401 * configure.ac: Bump to 2.53d.
7402 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7403 as of today, on Automake's team suggestion.

7407 Version 2.53c.
7409 2002-09-02 Akim Demaille <akim@epita.fr>
7411 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7412 SITE_MACRO_DIR.
7413 * configure.ac: Disable SITE_MACRO_DIR.
7415 2002-09-02 Jim Meyering <meyering@lucent.com>
7417 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7418 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7419 Also, tweak grammar: s/make sure to/be sure to/.
7421 2002-09-02 Paul Eggert <eggert@twinsun.com>
7423 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7424 directory names are generally preferable to physical names.
7426 2002-09-02 Akim Demaille <akim@epita.fr>
7428 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7429 Reported by Raja R. Harinath.
7430 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7431 * bin/autoupdate.in: Use error instead of die.
7433 2002-09-01 Paul Eggert <eggert@twinsun.com>
7435 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7436 ordinary shell concatenation rather than echo+tr+sed command that
7437 runs afoul of a long-line-related sed bug in Solaris 8.
7439 * bin/autoheader.in (parse_args): --warning -> --warnings.
7441 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7442 stdout, as traditional "ls" does.
7443 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7444 _AC_COMPILER_EXEEXT_O): Likewise.
7445 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7447 * bin/autoconf.as: Add --prepend-include option. This patch was
7448 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7449 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7451 * bin/autoconf.in, configure: Regenerate.
7453 * doc/autoconf.texi (Special Shell Variables): Mention
7454 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7456 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7457 MAILPATH and set PS1, PS2, PS4 to default values, to work
7458 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7459 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7460 the Autoconf documentation specifies; fall back to "unset" only if
7461 this fails. Use a shell for-loop for this rather than an m4 loop,
7462 to shorten the output script.
7464 2002-08-30 Paul Eggert <eggert@twinsun.com>
7466 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7467 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7468 for the CDPATH problem. Document PWD.
7469 (Limitations of Builtins): Document the problem that "cd $foo" and
7470 "ls $foo" may refer to different directories in shells conforming
7471 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7472 example, since the old example is now out of date.
7474 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7475 FOO" and "ls FOO" talk about different directories; this catches
7476 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7477 spaghetti.
7479 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7480 of rolling our own unset.
7481 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7482 in practice we needn't worry about CDPATH if unset doesn't work.
7484 * Makefile.in, aclocal.m4, bin/Makefile.in,
7485 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7486 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7487 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7488 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7489 tests/Makefile.in: Regenerate with Automake 1.6.3.
7491 * config/config.guess, config/config.sub, config/mkinstalldirs:
7492 Update.
7494 * configure: Regenerate with self.
7496 2002-08-30 Kevin Ryde <user42@zip.com.au>
7498 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7499 default output.
7501 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7503 * bin/autom4te.in (Request::load): Correctly test for "do" read
7504 failure.
7506 2002-08-29 Akim Demaille <akim@epita.fr>
7508 * lib/Autom4te/General.pm (&xqx): New.
7509 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7510 hand, which is not portable.
7511 (&error): New.
7512 * bin/autom4te.in: Use them.
7513 Use &error instead of die.
7514 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7515 Adjust.
7517 2002-08-17 Paul Eggert <eggert@twinsun.com>
7519 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7520 default list of compilers to try, since it was long ago superseded
7521 by the ksh fc builtin. Suggested by Steven G. Johnson.
7523 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7525 * doc/autoconf.texi (Invoking autom4te): End the option table,
7526 fixing a bug introduced by the previous patch.
7527 (Limitations of Make): Add a 'target lookup' subentry in the
7528 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7530 2002-07-29 Mark D. Roth <roth@feep.net>
7532 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7533 options and use $AUTOM4TE_PATH.
7534 * doc/autoconf.texi: Remove documentation of autom4te
7535 --include-envvar and --site-macro-subdir options and document
7536 use of $AUTOM4TE_PATH.
7537 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7538 arguments from each language section.
7540 2002-07-29 Paul Eggert <eggert@twinsun.com>
7542 * doc/install.texi: Include copyright symbol in copyright notice.
7544 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7545 Replace with:
7546 (AM_MAKEINFOFLAGS): New macro.
7547 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7548 * Makefile.am (INSTALL): Use the new macros.
7549 Use -o rather than --output, since "missing" does not grok --output.
7551 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7553 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7554 comments do not always work. Never trust the exit status of
7555 `make -k'.
7557 2002-07-24 Kevin Ryde <user42@zip.com.au>
7559 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7560 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7562 2002-07-23 Paul Eggert <eggert@twinsun.com>
7564 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7565 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7566 apparently treats PATH="nonexistent" as if it contained ".".
7567 Bug reported by Stefan `Sec' Zehl.
7569 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7571 * doc/autoconf.texi (Limitations of Make): Mention the special
7572 handling of the obj/ directory by BSD make.

7592 2002-07-18 Akim Demaille <akim@epita.fr>
7594 * config/config.guess, config/config.sub: Update.
7596 2002-07-18 Akim Demaille <akim@epita.fr>

7689 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
7690 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
7691 so that Emacs setups GNU style for perl-mode and cperl-mode.
7693 2002-06-27 Paul Eggert <eggert@twinsun.com>
7695 * config/install-sh: Quote $src. Prefer || to test's -o option,
7696 as per "Limitations of Builtins".
7697 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7698 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7700 * tests/mktests.sh: Use grep instead of fgrep, as per
7701 "Limitations of Builtins".
7703 2002-06-15 Paul Eggert <eggert@twinsun.com>
7705 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7706 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7707 so that we consistently test the just-built programs.
7708 * tests/wrappl.as: Likewise.
7710 2002-06-12 Paul Eggert <eggert@twinsun.com>
7712 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

7714 by Bruno Haible.
7715 * bin/autoheader.in (AUTOM4TE): Likewise.
7716 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7717 * bin/autoscan.in (autom4te): Likewise.
7718 * bin/autoupdate.in (autom4te): Likewise.
7720 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7721 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7722 on Solaris 2.5.1.
7724 2002-06-11 Andreas Schwab <schwab@suse.de>
7726 * doc/autoconf.texi: Add more dir entries.
7728 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7730 * bin/autom4te.in ($cache): Don't define using `$me', the name
7731 of the cache should not depend on the name under which autom4te
7732 was installed.
7734 2002-06-07 Akim Demaille <akim@epita.fr>
7736 * tests/tools.at (autoconf: forbidden tokens, basic)
7737 (autoconf: forbidden tokens, exceptions): Adjust to the change of
7738 words in autom4te.in.
7740 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7742 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7743 _AC_LANG_PROGRAM_C_F77_HOOKS.
7745 2002-06-07 Akim Demaille <akim@epita.fr>
7747 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
7748 rename as...
7749 (AC_REPLACE_FNMATCH): this.
7750 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
7751 AC_FUNC_FNMATCH_GNU.
7753 2002-06-07 Akim Demaille <akim@epita.fr>
7755 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7756 Rosetta Stone for Unix.
7758 2002-06-07 Akim Demaille <akim@epita.fr>
7760 * bin/autom4te.in (warn_forbidden): When rejecting a token,
7761 suggest m4_pattern_allow.
7762 Suggested by Adam J. Richter.
7764 2002-06-07 Akim Demaille <akim@epita.fr>
7766 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
7767 ac_config_libobj_dir.
7768 (AC_CONFIG_LIBOBJ_DIR): New.
7769 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
7770 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
7771 Use ac_config_libobj_dir to find the replacement files.
7772 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
7773 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)

7775 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
7776 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
7777 * tests/mktests.sh (ac_exclude_list): Don't check

7780 2002-06-06 Paul Eggert <eggert@twinsun.com>
7782 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7783 if ln doesn't work.
7784 * NEWS: Likewise.
7785 * doc/autoconf.texi (Configuration Links): Likewise.
7786 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
7788 2002-06-05 Paul Eggert <eggert@twinsun.com>
7790 * config/config.guess, config/config.sub, config/texinfo.tex:
7791 Update from masters.
7793 2002-05-29 Paul Eggert <eggert@twinsun.com>
7795 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
7796 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
7797 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

7804 * lib/m4sugar/Makefile.am (check-local): Likewise.
7805 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
7806 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
7808 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
7809 * doc/autoconf.texi (Particular Programs): Document them.
7810 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
7811 * NEWS: Likewise.
7813 2002-05-27 Paul Eggert <eggert@twinsun.com>
7815 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
7816 * NEWS, doc/autoconf.texi (Particular Types): Document it.
7817 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
7818 instead of AC_MBSTATE_T, which never existed.
7820 2002-05-23 Akim Demaille <akim@epita.fr>
7822 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7823 version of Autoconf that is discussed.
7825 2002-05-22 Paul Eggert <eggert@twinsun.com>
7827 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7828 from the default list of compilers to try. Suggested by
7829 Kate Hedstrom.
7830 * NEWS: Document the above.
7831 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7833 2002-05-17 Paul Eggert <eggert@twinsun.com>
7835 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7836 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7837 This improves on an earlier suggestion by H. Peter Anvin.
7839 2002-05-16 Paul Eggert <eggert@twinsun.com>
7841 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7842 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7843 Both macros now accept an optional source-dir arg.
7844 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7846 * NEWS: Document this.
7847 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7849 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7850 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7851 not for GNU extensions; this undoes part of the 2000-11-03 change,
7852 reverting to 2.13-compatible behavior.
7853 Add new optional argument DIR.
7854 (AC_FUNC_FNMATCH_GNU): New macro.
7856 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7858 2002-05-08 Paul Eggert <eggert@twinsun.com>
7860 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7861 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7862 and it causes a 'test' syntax error if it fails.
7863 Bug reported by Stephen Gildea.
7865 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7866 If prototypes are supported, use them to check this at compile-time,
7867 instead of trying to check it at run-time. If we must do a run-time
7868 check, assume that setvbuf is standard when cross-compiling, as
7869 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7870 Bug reported by Paul D. Smith.
7872 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7873 argument specifying location of getloadavg.c. This removes a
7874 FIXME. This idea was taken from Jim Meyering's implementation in
7875 textutils.
7876 * doc/autoconf.texi (Particular Functions): Document this.
7877 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7878 that's what the code does; this fixes a bug reported by
7879 Paul D. Smith.
7881 2002-05-03 Akim Demaille <akim@epita.fr>
7883 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7884 autopoint instead of gettextize.
7885 ($uses_alocal): Rename as...
7886 ($uses_aclocal): this.
7887 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7888 Suggested by Bruno Haible.
7890 2002-05-03 Akim Demaille <akim@epita.fr>
7892 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7894 2002-04-29 Paul Eggert <eggert@twinsun.com>
7896 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7897 files to be 1 second older; just set them to be the same time.
7898 Also, sleep 1 second after the first aclocal, to work around
7899 problems with sub-second time stamps on the input files.
7901 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7903 * doc/autoconf.texi: Mention "set -e -x" lossage
7904 under node "Limitations of Builtins".
7906 2002-04-29 Akim Demaille <akim@epita.fr>
7908 * doc/install.texi: Better wording for setting variables when
7909 running configure.
7910 From Christian Cornelssen.
7912 2002-04-29 Akim Demaille <akim@epita.fr>
7914 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7915 of lack of $LINENO support, then the test will compare the $LINENO
7916 in testsuite vs. the lineno in the test file. This is wrong, of
7917 course.
7918 Be sure to protect it.
7919 Reported by Patrick Welche.
7921 2002-04-25 Akim Demaille <akim@epita.fr>
7923 * doc/autoconf.texi (Obsolete Macros): Typo.
7924 Reported by Vladimir Volovich.
7926 2002-04-25 Akim Demaille <akim@epita.fr>
7928 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7929 than some of the input files, hence, on the second run of aclocal,
7930 if some of its input are younger, make them older.
7931 Suggested by Paul Eggert.
7933 2002-04-25 Akim Demaille <akim@epita.fr>
7935 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7936 Thanks to Paul Eggert.
7938 2002-04-25 Akim Demaille <akim@epita.fr>
7940 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7941 and ac_subst_vars be sh variables containing the list of
7942 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7943 DEFAULT diversion.
7944 (_AC_INIT_PREPARE): Use them to log them.
7945 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7946 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7947 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7948 _AC_SUBST_FILES and _AC_SUBST_VARS.
7949 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7951 2002-04-24 Akim Demaille <akim@epita.fr>
7953 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7954 autoheader, so that automake does not complain about a missing
7955 config.h.in that was to be created.
7957 2002-04-23 Akim Demaille <akim@epita.fr>
7959 * bin/autoheader.in (parse_args): --warning takes an argument.
7960 Fixes PR/220.
7962 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7964 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
7965 and bb.out when cleaning up.
7967 2002-04-22 Akim Demaille <akim@epita.fr>
7969 Version 2.53a.
7971 2002-04-22 Akim Demaille <akim@epita.fr>
7973 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
7975 2002-04-22 Akim Demaille <akim@epita.fr>
7977 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
7978 comma.
7979 Reported by Gregory Giannoni.
7981 2002-04-22 Akim Demaille <akim@epita.fr>
7983 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
7984 Fixes false failures on Darwin.
7986 2002-04-21 Paul Eggert <eggert@twinsun.com>
7988 * TODO, bin/autoupdate.in, doc/autoconf.texi,

7990 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,
7991 tests/tools.at: Minor spelling and grammar fixes.
7993 2002-04-20 Paul Eggert <eggert@twinsun.com>
7995 * doc/autoconf.texi (Shell Substitutions): Fix typos in yesterday's
7996 ZSH_VERSION fixes. Bug reported by Raja R Harinath.
7997 * lib/autotest/general.m4 (AT_INIT): Likewise.
7998 * tests/atgeneral.m4 (AT_INIT): Likewise.

8008 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
8009 Minor spelling and grammar fixes.
8011 * doc/autoconf.texi: Follow the outline suggested in the GNU
8012 Sample Texts sections of the Texinfo 4.2 manual. Most
8013 importantly, this makes sure that the copyright notices appear in
8014 all output formats. You probably need Texinfo 4.2 to generate
8015 the manual now.
8017 Fix some bugs when using "$@" when there might be zero positional
8018 arguments in cases where this matters.
8020 * bin/autoconf.as: Rewrite so that the problem does not come up.

8035 Use Zsh alias to work around problem.
8036 * tests/atgeneral.m4 (AT_INIT): Likewise.
8038 * tests/c.at: We can't have zero arguments, so remove workaround
8039 that is not portable to Zsh.
8041 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8043 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8044 from aclocal.m4 too.
8046 2002-04-12 Akim Demaille <akim@epita.fr>
8048 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
8050 2002-04-10 Akim Demaille <akim@epita.fr>
8052 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8053 workaround for ${1+"$@"}.
8054 * doc/autoconf.texi (Shell Substitutions): Explain it.
8055 From Oliver Kiddle and Peter Stephenson.
8057 Have M4sh perform minimal shell sanitizing.
8059 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8060 part into...
8061 (_AS_PREPARE): this new macro.
8062 (AS_PREPARE): New.
8063 (AS_INIT): Invoke AS_SHELL_SANITIZE.
8064 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8066 Adjust Autoconf and Autotest.
8068 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8069 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8070 * lib/autotest/general.m4 (AT_INIT): Likewise.
8071 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8072 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8073 AS_SHELL_SANITIZE.
8075 Use this M4sh to generate Autoconf's shell scripts.
8077 * tests/wrapsh.as: New, precursor of wrapsh.in.
8078 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8079 on Autotest and M4sh.
8080 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8081 (wrapsh.in): New target.
8082 * bin/autoconf.as: New, precursor of autoconf.in.
8083 (autoconf.in): New target.
8085 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
8087 * doc/autoconf.texi (Limitations of Make): Mention the issue
8088 with indented comments in rules.
8090 2002-04-09 Andreas Schwab <schwab@suse.de>
8092 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
8093 ac_top_builddir when setting ac_abs_top_builddir.
8095 2002-04-06 Kevin Ryde <user42@zip.com.au>
8097 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
8098 (Portable Shell): Cross reference to Systemology.
8100 2002-04-05 Akim Demaille <akim@epita.fr>
8102 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8103 directories when descending in a SUBDIRS.
8104 Reported by Ezra Peisach.
8106 2002-04-04 Andreas Schwab <schwab@suse.de>
8108 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8109 contains no literal separators.
8111 2002-04-03 Akim Demaille <akim@epita.fr>
8113 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8114 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8115 Use dnl, not the KILL diversion.
8116 Extracted from...
8117 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8118 (AC_CONFIG_LINKS): here.
8119 Adjust.
8120 Don't use the KILL diversion, as it kills spurious output, which
8121 results in failures being hidden.
8122 Use m4_defn where appropriate.
8123 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8124 after the second argument.
8125 Use m4_defn.
8126 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8127 syntax, as it is provided by M4sugar.
8128 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
8130 2002-04-03 Andreas Schwab <schwab@suse.de>
8132 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
8133 expanded if $# <= 2.
8135 * bin/autoreconf.in (autoreconf): Run automake after rerunning
8136 aclocal.
8138 2002-04-03 Akim Demaille <akim@epita.fr>
8140 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
8141 (_AC_COMPILER_EXEEXT_REJECT): New.
8142 Also recognize *.bb and *.bbg as compilation byproducts.
8143 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
8144 (_AC_COMPILER_OBJEXT): Use them.
8145 Fixes Debian #138666.
8147 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
8149 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
8151 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
8152 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
8153 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
8154 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
8155 (AC_C_CONST): Same.
8156 (AC_C_INLINE): Same.
8157 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
8158 * doc/autoconf.texi, NEWS: Document.
8159 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
8160 AC_C_CROSS.
8162 2002-04-02 Akim Demaille <akim@epita.fr>
8164 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
8165 _AS_MKDIR_P_PREPARE.
8167 2002-03-28 Kevin Ryde <user42@zip.com.au>
8169 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8170 to avoid versions of HP C which don't allow that.
8172 2002-03-27 Paul Eggert <eggert@twinsun.com>
8174 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8175 (AS_SHELL_SANITIZE): Invoke it.
8176 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
8178 2002-03-26 Akim Demaille <akim@epita.fr>
8180 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
8182 2002-03-26 Akim Demaille <akim@epita.fr>
8184 * doc/autoconf.texi (Introduction): The GNATS base moved.
8186 2002-03-25 Paul Eggert <eggert@twinsun.com>
8188 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8189 as POSIX requires, as it doesn't work with Zsh.
8190 * doc/autoconf.texi (Assignments): Document the problem.
8192 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8194 * doc/autoconf.texi (Limitations of Make): Mention more issue
8195 about VPATH, overriding of macros in sub-makes, and handling of
8196 SHELL.
8198 2002-03-21 Paul Eggert <eggert@twinsun.com>
8200 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8201 problem with here-document buffer boundaries.
8203 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8204 when reinvoking the shell, to work around problems with installers
8205 who put strange things like "cd" commands in their environments.
8207 2002-03-19 Akim Demaille <akim@epita.fr>
8209 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8210 From Aaron Ucko.
8212 2002-03-19 Akim Demaille <akim@epita.fr>
8214 * bin/autoscan.in (scan_file): Specify the location in `&used'
8215 invocations.
8216 From Nicolas Joly.
8218 2002-03-19 Akim Demaille <akim@epita.fr>
8220 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8221 From Nishio Futoshi.
8223 2002-03-19 Akim Demaille <akim@epita.fr>
8225 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8227 2002-03-18 Paul Eggert <eggert@twinsun.com>
8229 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8230 (Limitations of Usual Tools): Add mkdir section.
8232 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8233 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8234 back on AS_DIRNAME to compute prefixes otherwise; this is
8235 roughly what mkinstalldirs does. That way, we need not have
8236 our own filename disassembler. The old disassembler did not
8237 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8239 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8240 Create at_test_all by a series of assignments,
8241 not by a single assignment of a long string. The latter causes ksh
8242 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8243 presumably because of a buffer overrun.
8245 2002-03-14 Paul Eggert <eggert@twinsun.com>
8247 * lib/autotest/general.m4 (at_times_skip):
8248 Renamed from at_times. Now a boolean.
8249 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8250 says 'times: not found'.
8252 2002-03-14 Akim Demaille <akim@epita.fr>
8254 * bin/autoreconf.in (&study_gettextize): New.
8255 (&autoreconf): Handle newest gettextize.
8256 Rerun aclocal if needed.
8257 Suggested by Andreas Schwab.
8259 2002-03-13 Akim Demaille <akim@epita.fr>
8261 * doc/autoconf.texi (Special Shell Variables): More about IFS.
8263 2002-03-13 Akim Demaille <akim@epita.fr>
8265 * doc/autoconf.texi (Header Portability): New.
8266 Add information about stdint.h and inttypes.h from Paul Eggert.
8268 2002-03-13 Akim Demaille <akim@epita.fr>
8270 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8271 -p'.
8272 From Bob Proulx.
8274 2002-03-12 Akim Demaille <akim@epita.fr>
8276 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8277 m4_require.
8279 2002-03-11 Andreas Schwab <schwab@suse.de>
8281 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8282 does not do it if --with-lispdir is given.
8284 2002-03-08 Akim Demaille <akim@epita.fr>
8286 Version 2.53.
8288 2002-03-08 Akim Demaille <akim@epita.fr>
8290 * doc/autoconf.texi (Subdirectories): Clarify that the
8291 subdirectory should exist.
8293 2002-03-08 Akim Demaille <akim@epita.fr>
8295 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8297 2002-03-08 Akim Demaille <akim@epita.fr>
8299 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8300 aliases the actual variables, and modifications of the former
8301 affect the latter.
8303 2002-03-08 Akim Demaille <akim@epita.fr>
8305 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8306 because of C-c: have m4 output in tmp files, then mv them.
8308 2002-03-08 Akim Demaille <akim@epita.fr>
8310 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8311 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8312 * bin/ifnames.in: Copyright update.
8314 2002-03-08 Akim Demaille <akim@epita.fr>
8316 * doc/autoconf.texi (Invoking autom4te): New.
8318 2002-03-05 Akim Demaille <akim@epita.fr>
8320 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8321 Kevin Ryde.
8323 2002-03-05 Akim Demaille <akim@epita.fr>
8325 Version 2.52i.
8327 2002-03-04 Akim Demaille <akim@epita.fr>
8329 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8330 * lib/autoconf/general.m4 (AC_INIT): More informative error
8331 message for LIBOBJ.
8333 2002-03-04 Akim Demaille <akim@epita.fr>
8335 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8336 parallel builds.
8338 2002-03-04 Akim Demaille <akim@epita.fr>
8340 * doc/autoconf.texi (Transforming Names): Equality between target
8341 and host is irrelevant.
8342 (Specifying Names, Canonicalizing): Remove all references to the
8343 backward compatibility hooks. Rather, collect them all into...
8344 (Hosts and Cross-Compilation): this new section.
8345 * doc/install.texi (System Type): Ditto.
8346 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8347 that `--host' implies cross-compilation.
8349 2002-03-04 Akim Demaille <akim@epita.fr>
8351 * doc/autoconf.texi (Evaluation Macros): New.
8352 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8353 useless.
8354 (_m4_foreach): Define the variant with immediate evaluation so
8355 that it contains exactly the items, not an expression which
8356 evaluation is the current item.
8357 (m4_re_string, m4_re_word): Don't over quote them.
8359 2002-03-04 Akim Demaille <akim@epita.fr>
8361 Instead of having stacking `shift's evaluated at the end, let
8362 `foreach' loops immediately evaluate them.
8364 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8365 $*. This is the n-th time I change my mind, but hopefully this is
8366 the last...
8367 (m4_lquote): New.
8368 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8369 efficient.
8370 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8371 it was only a hack for m4_text_wrap.
8372 (m4_car2): Remove, replaced by...
8373 (m4_cdr): New.
8374 (_m4_foreach): Adjust.
8375 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8376 m4_bpatsubst for clarification.
8378 2002-03-04 Akim Demaille <akim@epita.fr>

8397 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
8398 message to be sent.
8400 2002-02-28 Kevin Ryde <user42@zip.com.au>

8404 2002-02-25 Akim Demaille <akim@epita.fr>
8406 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
8407 From Akinori Musha.
8409 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
8411 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8412 translate \r\n to \n.

8425 2002-02-07 Akim Demaille <akim@epita.fr>
8427 Fix Autoconf PR/207:
8428 AC_PREFIX_PROGRAM fails with dashed program names
8430 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8431 variable when looking for the prefix program.
8432 Now it also works for shell variables.
8434 2002-02-07 Akim Demaille <akim@epita.fr>
8436 * doc/autoconf.texi (Limitations of Builtins): More about
8437 case/esac.
8439 2002-02-06 Akim Demaille <akim@epita.fr>
8441 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
8442 case/esac, some shells don't support it.
8443 Reported by Zack Weinberg.

8446 2002-02-06 Akim Demaille <akim@epita.fr>
8448 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8449 sure not to introduce newlines in at_groups.
8450 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8452 2002-02-06 Akim Demaille <akim@epita.fr>
8454 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8455 is not available.
8457 2002-02-05 Paul Eggert <eggert@twinsun.com>
8459 * doc/autoconf.texi (Specific Compiler Characteristics):
8460 Describe HP-UX cc bug workaround more accurately.
8461 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
8462 not unsigned long.
8463 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8464 cross-compilers, too. This undoes some of the most recent change
8465 to this file.
8467 2002-02-05 Akim Demaille <akim@epita.fr>
8469 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8470 to make sure they are up to date when `check' is run.
8472 2002-02-05 Akim Demaille <akim@epita.fr>
8474 * doc/autoconf.texi (Making testsuite Scripts): Document
8475 package.m4.
8477 2002-02-05 Akim Demaille <akim@epita.fr>
8479 * lib/freeze.mk: New.
8481 2002-02-05 Akim Demaille <akim@epita.fr>
8483 Implement `autom4te --freeze'.
8485 * bin/autom4te.in (&freeze): New.
8486 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8487 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8489 2002-02-05 Akim Demaille <akim@epita.fr>
8491 * bin/autom4te.in (&parse_args): Implement `frozen files are
8492 optional are the sum of the previous files on the command line'.
8493 Also, pass `--reload-state=' on them, so...
8494 (handle_m4): don't.
8495 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8496 (M4sh): Rely on M4sugar.
8497 (Autotest, M4sh, M4sugar): Use frozen files.
8499 2002-01-31 Akim Demaille <akim@epita.fr>
8501 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8502 * doc/autoconf.texi (Initializing configure): Adjust.
8504 2002-01-30 Akim Demaille <akim@epita.fr>
8506 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8507 alphanumeric to `-' instead of `_'.
8509 2002-01-30 Akim Demaille <akim@epita.fr>
8511 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8512 for plain code, the other for cross-compilation code. The latter
8513 is now run with GCC only.
8514 * doc/autoconf.texi (Compilers and Preprocessors): New.
8516 2002-01-30 Akim Demaille <akim@epita.fr>
8518 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8519 values.
8520 * doc/autoconf.texi (Initializing configure): Explain how to
8521 change AC_INIT default values.
8523 2002-01-29 Akim Demaille <akim@epita.fr>
8525 * tests/torture.at (Configuring subdirectories): Use configure.in,
8526 so that aclocal 1.4 works.
8527 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8529 2002-01-28 Akim Demaille <akim@epita.fr>
8531 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8532 needs an argument.
8534 2002-01-28 Akim Demaille <akim@epita.fr>
8536 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8537 AUTOTEST_PATH *after* it was set.
8538 Don't put `.' in the PATH: the user should be precise and `./' if
8539 needed. In addition, given that the test suite does some `cd', if
8540 `.' is in the path, the `tested programs' sections will report
8541 programs found in the test suite's directory, while during the
8542 tests (performed in their own directory), these programs are no
8543 longer visible. In other words, the results is confusing and
8544 useless.
8545 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8547 2002-01-24 Akim Demaille <akim@epita.fr>
8549 Version 2.52g.
8551 2002-01-24 Akim Demaille <akim@epita.fr>

8554 * doc/autoconf.texi: Finally add Akim as an author.
8556 2002-01-24 Akim Demaille <akim@epita.fr>
8558 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8559 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8560 Bourne. Use /bin/sh.
8561 From Andreas Buening.
8563 2002-01-24 Akim Demaille <akim@epita.fr>
8565 * config/config.guess, config/config.sub, config/texinfo.tex:
8566 Update from masters.
8568 2002-01-24 Akim Demaille <akim@epita.fr>
8570 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.

8573 * config/missing.m4, config/sanity.m4, config/select.m4,
8574 * config/strip.m4: Remove, to ease sync'ing with any version of
8575 Automake.

8579 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8580 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
8581 Reported by Geir Ove Myhr.
8583 2002-01-21 Akim Demaille <akim@epita.fr>
8585 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
8587 2002-01-21 Akim Demaille <akim@epita.fr>
8589 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8590 message on invalid options.
8591 * bin/autom4te.in (parse_args): Don't use
8592 Autoconf::General::getopt with non valid options.
8594 2002-01-17 Jim Meyering <meyering@lucent.com>
8596 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8597 $ac_cv_exeext so we don't use an old, invalid, cached value.
8599 2002-01-11 Akim Demaille <akim@epita.fr>
8601 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
8602 Meyering.

8604 limitation.

8608 2002-01-06 Akim Demaille <akim@epita.fr>
8610 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8611 package.m4, since is really depends upon configure.ac, not
8612 configure.
8613 * doc/autoconf.texi (testsuite Scripts): Adjust.
8614 * tests/Makefile.am (package.m4): New.
8615 EXTRA_DIST it since its a source.
8617 2002-01-06 Akim Demaille <akim@epita.fr>
8619 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8620 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8621 and PACKAGE_BUGREPORT from here...
8622 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8623 arguments.
8624 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8625 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8626 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8627 * tests/tools.at (autoheader): Adjust.
8628 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8630 2002-01-06 Akim Demaille <akim@epita.fr>

8634 2002-01-03 Akim Demaille <akim@epita.fr>
8636 * doc/autoconf.texi (Output): Improved wording regarding use of
8637 AC_OUTPUT.
8638 From Olly Betts.
8640 2001-12-18 Kevin Ryde <user42@zip.com.au>
8642 * doc/autoconf.texi (Function Portability): Add notes on sscanf
8643 sometimes needing writable input.
8645 2001-12-17 Jim Meyering <meyering@lucent.com>
8647 * doc/autoconf.texi (New Macros): Tweak wording.
8649 2001-12-14 Akim Demaille <akim@epita.fr>
8651 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8652 trailing files, don't apply `-rf' to files which might not be
8653 created by configure (core, core.*, and *.core), but just `rm -f'.
8654 Suggested by Jonathan Kamens.
8656 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8658 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8660 2001-12-14 Akim Demaille <akim@epita.fr>
8662 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8664 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8666 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8667 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8668 abs_srcdir, top_srcpath to abs_top_srcdir.
8669 (_AC_OUTPUT_FILES): Adjust.
8670 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,

8672 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8674 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8676 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8677 C/Fortran linking on HP/UX, by extracting the Fortran library
8678 search path from the LPATH line in the $F77 -v output.
8680 2001-12-12 Kevin Ryde <user42@zip.com.au>
8682 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8683 forbidden file descriptors table.
8685 2001-11-26 Akim Demaille <akim@epita.fr>
8687 * bin/autoscan.in (%c_keywords): Build it at top level.
8688 Map to 1 in order to simplify its uses.
8690 2001-11-26 Akim Demaille <akim@epita.fr>
8692 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8693 Remove $filepath, useless.
8694 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8695 variables, they are really part of the tokens.
8696 Split the input line on spaces and then look for tokens.
8697 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8698 because of `lex$U.$(OBJEXT)'.
8699 (&scan_files): Use "@list" instead of join.
8700 * doc/Makefile.am (CLEANFILES): Add *.fns.
8702 2001-11-26 Akim Demaille <akim@epita.fr>
8704 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8705 Remove, replaced by...
8706 * tests/wrappl.in: Be common for all the Perl executables.
8707 In particular autoscan and autoheader want -I.
8708 * configure.ac: Adjust.
8709 * lib/autoscan/headers: errno.h is portable.
8711 2001-11-26 Akim Demaille <akim@epita.fr>
8713 * bin/autoscan.in (used): New.
8714 Use it.
8716 2001-11-26 Akim Demaille <akim@epita.fr>
8718 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8719 directives.

8727 Before, having a line containing the opening of a multi line
8728 comment made the whole line be ignored.
8730 2001-11-26 Akim Demaille <akim@epita.fr>
8732 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8733 (testsuite Scripts): Be one of its subsection.
8734 (Autotest Logs): New.
8736 2001-11-26 Akim Demaille <akim@epita.fr>
8738 Test groups are now run two directories deeper.
8740 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8741 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8742 at_top_builddir.
8743 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8744 top_srcdir, builddir and top_builddir.
8745 Use `at_*dir' relatively to the directory containing the
8746 suite, use `*dir' when relatively to the current group dir.
8748 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8750 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8751 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8752 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8753 spelling errors.
8755 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8757 * doc/autoconf.texi (Using System Type): Add an example of `case
8758 $host' usage so people quit using `case $target' everywhere.
8760 2001-11-22 Akim Demaille <akim@epita.fr>
8762 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8763 spotted by Jim Meyering.
8765 2001-11-16 Paul Eggert <eggert@twinsun.com>
8767 This patch implements a `long double' suggestion by Oliver Kiddle.
8769 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8770 static, to catch errors if the value isn't known at compile-time
8771 and the compiler supports dynamic arrays. Change its name from
8772 `_array_' to `test_array' to avoid potential name clashes.
8773 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8774 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8775 better than double. Catch a bug in GCC 2.95.2 x86.
8776 * doc/autoconf.texi (C Compiler): Document the above.
8777 * NEWS: Likewise.
8779 2001-11-13 Akim Demaille <akim@epita.fr>
8781 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8782 hand.
8783 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8785 2001-11-13 Akim Demaille <akim@epita.fr>
8787 * lib/autotest/general.m4 (AT_INIT): After having run the test
8788 group, go back to the initial directory, not to at_suite_dir.
8790 2001-11-13 Akim Demaille <akim@epita.fr>
8792 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8793 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8794 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8795 option.
8796 (AT_CHECK_CONFIGURE): Use absolute paths.
8797 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8798 The problem is still the old one: there is no means in M4 (that I
8799 know about) to create a defining macro, because there is no means
8800 to create `$1' etc., therefore, the defining macro ``swallows''
8801 all the arguments meant to the defined macro.
8803 2001-11-13 Akim Demaille <akim@epita.fr>
8805 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8806 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8807 configure.ac.
8808 * tests/aclocal.m4: Remove, as it is no longer used.
8810 2001-11-13 Akim Demaille <akim@epita.fr>
8812 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8813 variable names when referring to a single test group, or to
8814 `suite' when referring to the whole test suite.
8815 `at_last_test' is removed: m4 compute at_format itself.
8816 (at_stdout, at_stder1, at_stderr): New variables.
8817 (AT_CHECK): Use them.
8819 2001-11-13 Akim Demaille <akim@epita.fr>
8821 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8822 in PATH.
8823 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8824 Do it as soon as a test fails, don't wait till the end of the test
8825 suite.
8826 Don't remove $as_me.[0-9]*, since these files no longer exist.
8828 2001-11-13 Akim Demaille <akim@epita.fr>
8830 * tests/tools.at: Use absolute paths, since we are no longer run
8831 in place.
8833 2001-11-13 Akim Demaille <akim@epita.fr>
8835 Now that tests are running in their own private dir, there is no
8836 need to list the files to remove at the end of tests groups.
8838 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8839 (AT_data_files, at_data_files): Remove.
8840 (AT_CLEANUP, AT_DATA): Simplify.
8841 (AT_INIT): Adjust.
8842 Remove the group dir if !debug && !failed.
8843 * tests/atspecific.m4: Adjust.
8845 2001-11-13 Akim Demaille <akim@epita.fr>
8847 Start a new layout for Autotest: `testsuite' creates
8848 `testsuite.dir' in which the at-check-line etc. files are to be
8849 found, and `testsuite.dir/003' where the test group 3 is run.
8851 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8852 at_check_line_file, at_format, at_test_normalized, at_group_dir
8853 are new variables.
8854 Create the directories.
8855 Use absolute paths for at- files.
8856 (AT_CHECK): Adjust.
8858 2001-11-11 Michael Matz <matz@kde.org>
8860 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8861 (m4_car2): New.
8862 (m4_car): Properly quote arguments.
8864 2001-11-13 Akim Demaille <akim@epita.fr>
8866 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8867 with stricter rules on LIBOBJS.
8869 2001-11-12 Paul Eggert <eggert@twinsun.com>
8871 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8872 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8873 __PROTOTYPES too.
8875 2001-11-12 Akim Demaille <akim@epita.fr>
8877 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8879 2001-11-12 Akim Demaille <akim@epita.fr>
8881 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8882 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8883 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8884 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8885 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8886 specify to what the macro should be defined (typically to 1).
8888 2001-11-12 Akim Demaille <akim@epita.fr>
8890 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8891 From Jim Meyering.
8893 2001-11-12 Akim Demaille <akim@epita.fr>
8895 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8896 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8897 definition used by Automake where LEX is +/- "${missing} lex" and
8898 `missing' itself contains variables.
8900 2001-11-12 Akim Demaille <akim@epita.fr>
8902 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8903 Now that M4sh pushes BODY, the comments were output at the end of
8904 the test suites.
8906 2001-11-08 Akim Demaille <akim@epita.fr>
8908 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8909 that we can trace macros from aclocal.m4.
8910 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8911 obsoleted, and redirect to the former anyway.
8912 Reported by Ralf Corsepius.
8914 2001-11-08 Akim Demaille <akim@epita.fr>
8916 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8917 processed only if present.
8918 * tests/torture.at (Configuring subdirectories): Use autoreconf
8919 instead of successive calls to autoconf.
8920 Add a nonexistent subdirectory to exercise the patch above.
8921 Reported by Ralf Corsepius.
8923 2001-11-08 Kevin Ryde <user42@zip.com.au>
8925 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8926 doesn't accept .S files.
8928 2001-11-07 Akim Demaille <akim@epita.fr>
8930 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8931 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8932 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8933 * bin/autom4te.in (warn_forbidden): New.
8934 (handle_output): Use it.
8935 Read m4_pattern_forbid with messages.
8937 2001-11-05 Akim Demaille <akim@epita.fr>
8939 * bin/autom4te.in (--normalize): Remove.
8940 * lib/autom4te.in: Adjust.
8942 2001-11-05 Akim Demaille <akim@epita.fr>
8944 * tests/Makefile.am (testsuite): Rename this target as...

8946 From Nicolas Joly.
8948 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8950 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8951 the --prefix option, also remove it's argument.
8953 2001-11-05 Akim Demaille <akim@epita.fr>
8955 * doc/autoconf.texi (testsuite Invocation): Update.
8956 (Writing testsuite.at): Update.
8958 2001-11-03 Akim Demaille <akim@epita.fr>
8960 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8962 2001-11-03 Akim Demaille <akim@epita.fr>
8964 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8965 (&file_name_is_absolute): New, wrappers around routines from
8966 File::Spec.
8967 Use and export them.
8968 (&find_configure_ac): Optionally take a directory where to look at.
8969 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8970 the arguments.
8971 Default @ARGV to `.', not find_configure_ac.
8972 (&autoreconf): Argument is a directory.
8973 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8974 * doc/autoconf.texi (autoreconf Invocation): Update.
8976 2001-11-03 Akim Demaille <akim@epita.fr>
8978 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8979 (@export_forward_subs): New.
8980 Add basename, dirname, and fileparse.
8981 (@EXPORT): Adjust.
8982 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8983 Don't look for aclocal flags if we already know aclocal is not
8984 used.
8985 Move aclocal.m4t only if it exists.
8986 Reported by Ezra Peisach.
8988 2001-11-03 Akim Demaille <akim@epita.fr>
8990 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8991 passed on command line, defaulting to ./configure.ac if present.
8992 (&maybe_autoreconf, File::Find): Remove, unused.
8993 (&autoreconf): If autoconf is not used, don't try to trace.
8995 2001-11-02 Akim Demaille <akim@epita.fr>
8997 * configure.ac: Bump to 2.52g.
8999 2001-11-02 Akim Demaille <akim@epita.fr>
9001 Version 2.52f.
9003 2001-11-02 Akim Demaille <akim@epita.fr>
9005 * config/config.guess, config/config.sub, doc/standards.texi:
9006 * config/lispdir.m4: Update from masters.
9007 * configure.ac: Bump to 2.52f.
9009 2001-11-02 Akim Demaille <akim@epita.fr>
9011 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9012 Don't run aclocal when aclocal.m4 is not from aclocal.
9013 From Ezra Peisach.
9014 Don't run libtoolize and gettextize if --install is not given.
9016 2001-11-01 Paul Eggert <eggert@twinsun.com>
9018 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9019 be invoked before _AS_LINENO_PREPARE.
9020 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9021 than character ranges.
9023 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9024 invoking AS_BASENAME. Set the locale variables to 'C' if
9025 possible, as POSIX requires this to get the traditional
9026 behavior.
9027 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9029 2001-10-31 Paul Eggert <eggert@twinsun.com>
9031 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9032 with {}, as that triggers a bug in Bash 2.05.
9034 (_AS_LINENO_PREPARE): Use Sed rather than
9035 Awk. Fix the sed prepass to work even if there are multiple
9036 instances of $LINENO on the same line. Do not substitute for
9037 other variables like $LINENOT. Do not check file dates; such a
9038 check is unreliable on sufficiently fast machines, and removing
9039 the check makes the code simpler and more reliable. Check for
9040 output and chmod failures.
9042 * doc/autoconf.texi (Special Shell Variables): Document
9043 the above.
9045 2001-10-31 Akim Demaille <akim@epita.fr>
9047 * tests/Makefile.am (atconfig): Remove this target, Automake
9048 handles it now.
9050 2001-10-31 Akim Demaille <akim@epita.fr>
9052 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9053 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9054 provided, while it is optional.
9055 * configure.ac: Adjust.
9057 2001-10-26 Paul Eggert <eggert@twinsun.com>
9059 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9060 lib/Autom4te/Struct.pm:
9061 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9062 with 5.005_02.
9064 * doc/autoconf.texi (Special Shell Variables): Document some
9065 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9067 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9068 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9069 eval $LINENO is not portable in practice.
9071 2001-10-24 Akim Demaille <akim@epita.fr>
9073 * lib/Autom4te/General.pm (backname): New.
9075 2001-10-24 Akim Demaille <akim@epita.fr>
9077 * m4/: Remove, merged into...
9078 * config/: here.
9080 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9082 * doc/autoconf.texi (Shellology): Mention the problems with bash
9083 2.05's use of ANSI quoting in its `set' builtin.
9085 2001-10-22 Paul Eggert <eggert@twinsun.com>
9087 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9088 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9089 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9090 POSIX decided to standardize on the int flavor of strerror_r.
9091 Always do char* test, as there's no reason not to.
9092 Assign to a char* var, to catch strerror_r that returns int*.
9094 * doc/autoconf.texi (Particular Functions):
9095 Document the above changes. Also, document the fact that
9096 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9098 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9100 2001-10-20 Akim Demaille <akim@epita.fr>
9102 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9103 the executable was missing from the log.
9105 2001-10-20 Akim Demaille <akim@epita.fr>
9107 * lib/Autom4te/General.pm (&update_file): If destination is
9108 unchanged, remove the source.
9109 (&up_to_date_p): Don't be verbose, be debug.
9110 * bin/autoreconf.in: No longer support --m4dir.
9111 (&autoreconf): Display the full path of the configure.ac we are
9112 studying.
9113 Trace it only once.
9114 Be sure to honor --force with gettextize.
9115 Always run aclocal.
9116 * doc/autoconf.texi: Adjust.
9118 2001-10-20 Akim Demaille <akim@epita.fr>
9120 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9121 Remove, dead.
9122 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9123 `intl' is already present, as it refuses unless --force.
9124 (&parse_args): Use -I, --include instead of the old Autoconf
9125 options.
9126 ($localdir, $autoconf_dir): Remove.
9127 (@include): New.
9128 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9130 2001-10-19 Jens Petersen <petersen@redhat.com>
9132 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9144 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9145 comment, explain how to install automatic mode selection.
9146 From Russ Allbery.
9148 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9150 * bin/autoreconf.in (autoreconf): Display the path to the
9151 configure.ac being studied.
9153 2001-10-18 Paul Eggert <eggert@twinsun.com>
9155 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9156 long, to work around a bug in the HP C compiler version HP92453-01
9157 B.11.11.23709.GP.
9159 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9160 (AS_BASENAME_EXPR): New macro.
9161 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9162 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9163 and fall back on 'sed' only if the other two fail. This makes
9164 AS_BASENAME act more like AS_DIRNAME.
9165 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9166 contains white space.
9167 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9168 Use AS_DIRNAME, since I think it's now DOS-friendly.
9169 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9170 Allow "dirname //FOO" to return either / or //, as POSIX allows
9171 either behavior.
9173 2001-10-10 Akim Demaille <akim@epita.fr>
9175 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9176 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9177 From Eric Sharkey.

9309 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
9310 shell does not support LINENO, and if CONFIG_SHELL is unset or
9311 empty, and if we can find a shell that does support LINENO,
9312 then set CONFIG_SHELL to that shell and then re-execute
9313 ourselves with CONFIG_SHELL.
9315 2001-10-05 Paul Eggert <eggert@twinsun.com>
9317 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9318 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9319 build of $(TESTSUITE).
9321 2001-10-05 Akim Demaille <akim@epita.fr>

9353 2001-10-02 Paul Eggert <eggert@twinsun.com>
9355 * doc/autoconf.texi (Limitations of Builtins): You can't use
9356 "source"; it's not portable. Remove confusing and
9357 somewhat-incorrect example involving "." and "/".
9359 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
9360 compatibility with POSIX shells.
9362 2001-10-02 Akim Demaille <akim@epita.fr>
9364 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
9365 instead of exec'ing to preserve $0 and $@.
9367 2001-10-01 Akim Demaille <akim@epita.fr>
9369 * tests/testsuite (AT_INIT) <at_pass_list>: New.

9388 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
9389 Don't use nested parenthesization. This patch was originally
9390 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
9391 but somehow it didn't get incorporated then.
9392 * doc/autoconf.texi (Limitations of Usual Tools):
9393 Clarify remark about sed and nested parenthesization.
9395 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
9396 Report an error if the size cannot be determined even though
9397 the type exists.
9398 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9399 Check for `expr' arithmetic overflow, and for compilation failure,
9400 and invoke a new argument $4 if either is discovered.
9401 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9402 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9404 2001-09-28 Akim Demaille <akim@epita.fr>
9406 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

9424 status when executing the ACTION-IF-FALSE.
9425 * tests/base.at (AC_TRY_*): Rename as...

9431 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
9432 * tests/c.at (Extensions, C keywords)
9433 (Broken/missing compilers, AC_PROG_CPP with warnings)
9434 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
9435 (AC_PROG_CPP requires AC_PROG_CC): here and...
9436 * tests/fortran.at (GNU Fortran 77): there.
9437 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9438 AC_TRY_RUN is about compilation, not shell commands.
9439 (Test Programs): AC_TRY_RUN works as used to be advertised.
9441 2001-09-27 Akim Demaille <akim@epita.fr>
9443 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9444 Raja R Harinath:
9445 Be sure to detect when $LINENO always returns the same value.
9446 Look for the original script, basename($0) is certainly not
9447 enough.
9448 Pass the CLI arguments to `$as_me.lineno'.
9450 2001-09-25 Akim Demaille <akim@epita.fr>
9452 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
9453 Be sure the close and reopen the LOG fd before and after using tee

9457 2001-09-23 Akim Demaille <akim@epita.fr>
9459 * bin/autom4te.in (parse_args): There can be several invocations
9460 of --language now.
9462 2001-09-23 Akim Demaille <akim@epita.fr>
9464 * doc/autoconf.texi (Top): Wrap in @ifnottex.
9466 2001-09-23 Akim Demaille <akim@epita.fr>
9468 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
9469 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
9470 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
9471 builddir, buildpath, top_builddir, and top_buildpath.
9472 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
9473 the current directory.
9474 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir

9476 Skip nonexistent dirs.
9477 * doc/autoconf.texi (Preset Output Variables): Document these
9478 variables.
9480 * lib/autotest/general.m4: Do not reset AT_victims.
9481 Don't compute at_srcdir nor at_top_srcdir.
9483 * tests/tools.at: Hence use top_srcdir.
9485 * tests/Makefile.am, tests/autoconf, tests/autoheader,
9486 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
9487 Remove.

9498 * doc/autoconf.texi (Common Shell Constructs): Rename as...
9499 (Programming in M4sh): this.

9529 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
9531 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,
9532 * m4/install-sh.m4, m4/missing.m4, m4/sanity.m4, m4/strip.m4: Updated
9533 to match current versions from CVS Automake.
9535 2001-09-23 Alexandre Duret-Lutz <duret_g@epita.fr>

9540 2001-09-22 Akim Demaille <akim@epita.fr>
9542 * lib/autoconf/autotest.m4: Create `package.m4'.
9543 * tests/Makefile.am (package.m4): Remove.
9545 2001-09-22 Akim Demaille <akim@epita.fr>
9547 Rely on `$LINENO' when possible instead of `__oline__'.
9549 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
9550 `$LINENO' support replacement when not supported.
9551 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
9552 them explicitly to be sure they are not output before this section
9553 (via m4_require). Cosmetic only.

9555 * lib/autoconf/programs.m4: Replace all the occurrences of
9556 `__oline__' with `$LINENO'.
9557 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
9559 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>

9562 character (u: -> ue) in a code comment.
9563 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
9564 it works.
9566 2001-09-21 Akim Demaille <akim@epita.fr>
9568 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9569 Suggested by Jim Meyering.
9571 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9573 * lib/autoconf/programs.m4: Use extensions listed in

9581 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
9583 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9586 PATH_SEPARATOR.
9587 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9588 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9589 be used instead of ':'.
9590 * lib/autotest/general.m4: Replace occurrences of ':' in
9591 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9593 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9596 arguments. Fixed a typo.
9598 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9600 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9601 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9603 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9605 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
9606 * bin/autoupdate.in: Ditto.
9607 * bin/autoheader.in: Reworded a few comments.

9612 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9614 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9615 already have $file). Set output files to binary mode (helps avoid
9616 CR issues on DOSish systems).
9618 2001-09-19 Akim Demaille <akim@epita.fr>
9620 * lib/autotest/general.m4: Englishoes.
9621 From Tim Van Holder and Alexey Mahotkin.
9623 2001-09-18 Paul Eggert <eggert@twinsun.com>
9625 * doc/autoconf.texi (Common Shell Constructs): New node,
9626 documenting AS_DIRNAME.
9627 (Limitations of Usual Tools): Refer to it when discussing dirname.
9628 Also, update discussion of POSIX standard to reflect latest draft.
9630 * lib/autoconf/c.m4:
9631 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9633 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9634 Do not pass a first argument with leading '-'
9635 to expr, by parenthesizing initial integers that might be negative.
9637 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9638 now merely checks whether it is an error to pass an argument
9639 to getpgrp.
9641 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9642 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9643 whether it is a (compile-time) error to pass an argument to
9644 getpgrp. This simpler test supports the revised documentation,
9645 and is all that AC_FUNC_GETPGRP's users really need.
9647 2001-09-18 Akim Demaille <akim@epita.fr>
9649 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9651 2001-09-18 Akim Demaille <akim@epita.fr>

9657 2001-09-18 Paul Wagland <paul@wagland.net>
9659 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9660 correctly.
9661 Add test for AS_BASENAME.
9662 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9663 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9664 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9665 * tests/base.at: Fixed the expected responses. The old ones were
9666 one line out...
9667 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9668 the documentation claims it should (and how it behaved in 2.13).
9670 2001-09-18 Akim Demaille <akim@epita.fr>
9672 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9673 the AC_CONFIG_COMMANDS invocation.
9674 This also solves the name clash problems.
9675 Don't set the package's ID.
9676 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9677 No longer to be shipped.
9678 (version.in): Remove.
9679 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9680 * lib/autoconf/status.m4: Adjust.
9681 Use `m4_PACKAGE_STRING'.
9682 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9683 the only optional argument is the name of the test suite.
9684 Expect `package.m4' to define the package signature.
9685 * lib/autom4te.in (Autotest): Add `package.m4?'.
9686 * tests/Makefile.am (package.m4): New.
9687 * tests/suite.at: ifnames is a victim.
9689 2001-09-18 Akim Demaille <akim@epita.fr>
9691 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9692 AC_LIBSOURCE, AC_CONFIG_FILES.
9693 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9694 program version string doesn't match the package's.
9695 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9696 after `(cached)'.
9698 2001-09-17 Paul Eggert <eggert@twinsun.com>
9700 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9701 Allow expression to return any value that can fit into unsigned long
9702 (not int, as before). Check for output errors.
9704 2001-09-17 Bruno Haible <haible@ilog.fr>
9706 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9707 Always include <stdio.h> and <stdlib.h>. Evaluate
9708 the expression in an extra function before these includes. Call
9709 fprintf "%d" only after ensuring the argument is of type 'int'.
9710 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9712 2001-09-17 Paul Eggert <eggert@twinsun.com>
9714 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9715 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9716 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9717 when they don't exist.
9719 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9720 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9721 need it.
9723 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9724 version with the version used by fileutils 4.1, except use
9725 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9726 we don't need it.
9728 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9730 2001-09-13 Akim Demaille <akim@epita.fr>
9732 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
9733 _first_.
9734 Reported by Gerrit P. Haase.
9736 2001-09-13 Akim Demaille <akim@epita.fr>
9738 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9754 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
9755 Likewise.
9756 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
9757 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
9758 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
9759 AT_tests_all for consistency.
9760 Set at_victims.
9761 (AT_VICTIMS): Similar to AT_KEYWORDS.
9762 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
9764 2001-09-13 Akim Demaille <akim@epita.fr>
9766 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9768 2001-09-13 Akim Demaille <akim@epita.fr>
9770 * lib/autotest/general.m4 (AT_INIT): Create and remove
9771 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9772 test suites can cohabit.
9774 2001-09-13 Akim Demaille <akim@epita.fr>
9776 * tests/mktests.sh: Don't output banners for empty test files.
9778 2001-09-13 Akim Demaille <akim@epita.fr>
9780 Test suites can be run independently of configure.
9782 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
9783 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

9796 (AT_CHECK_PERL_SYNTAX): New.
9797 (Syntax of the Perl scripts): Check ifnames.
9798 * tests/ifnames: New.
9800 2001-09-13 Akim Demaille <akim@epita.fr>
9802 * lib/autotest/general.m4 (AT_INIT): Let --keywords also match
9803 test group titles.
9804 * tests/atspecific.m4 (AT_CHECK_AU_MACRO): AT_KEYWORDS(autoupdate).

9826 2001-09-10 Akim Demaille <akim@epita.fr>
9828 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

9844 2001-09-07 Akim Demaille <akim@epita.fr>
9846 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5

9848 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
9849 related variables into `at_package_*'.
9850 * lib/autotest/general.m4 (AT_VICTIMS): New.

9859 Move toward possibly stand-alone test suites.
9861 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
9862 in addition, it introduces useless differences in logs.
9863 (AT_INIT): Let atconfig and atlocal be both optional.
9864 Adjust PATH computation.
9865 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

9876 From Uwe Seimet.
9878 2001-09-05 Akim Demaille <akim@epita.fr>
9880 * bin/autom4te.in: --language is -l, not -s.
9882 2001-09-05 Akim Demaille <akim@epita.fr>
9884 Be ready to handle filenames as stupid as `dnl.at', for if even
9885 the maintainer is dumb enough to do that...
9887 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9888 excellence in M4 quotation: consider `__file__' is active.
9890 And BTW, when invoking m4, pass the --include in the right order:
9891 the wrong one.
9893 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
9894 4m.
9896 2001-09-05 Akim Demaille <akim@epita.fr>
9898 * lib/Autom4te/XFile.pm: New lib file.
9899 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,

9914 * doc/autoconf.texi (autoscan Invocation): Adjust.
9916 2001-09-05 Akim Demaille <akim@epita.fr>
9918 CVS GNU M4 doesn't like `undefine(undefined)'.
9920 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
9921 New, extracted from main.
9922 Use IO::File wherever possible.
9923 (input.m4): Be constant, use -I instead of hard coding $tmp.
9924 Therefore be a quoted heredoc.
9925 Don't invoke `_au_disable', since ac was not loaded, but just
9926 `unm4.m4'.
9928 2001-08-31 Akim Demaille <akim@epita.fr>
9930 Version 2.52d.
9932 2001-08-31 Akim Demaille <akim@epita.fr>

9935 previous patch.

9942 Reported by Nicolas Joly.
9944 2001-08-31 Akim Demaille <akim@epita.fr>
9946 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.

9951 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
9953 2001-08-31 Akim Demaille <akim@epita.fr>
9955 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9956 (testsuite Scripts): There is no such thing as `atconfig.in'.
9957 And actually one diagram is missing: test suite runtime.
9959 2001-08-31 Akim Demaille <akim@epita.fr>
9961 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9962 inverse order.
9964 2001-08-31 Akim Demaille <akim@epita.fr>
9966 * bin/autoupdate.in (@include): `installcheck' revealed the path
9967 to m4sugar was lacking!
9969 2001-08-31 Akim Demaille <akim@epita.fr>
9971 * man/Makefile.am (.x.1): We really have to pass
9972 autom4te_perllibdir.
9974 2001-08-31 Akim Demaille <akim@epita.fr>
9976 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9977 debug scripts, in particular passing explicitly listed tests to
9978 run is stupid.
9980 2001-08-31 Akim Demaille <akim@epita.fr>
9982 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9983 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9984 Use directly autom4te, not autoconf.
9985 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
9987 2001-08-31 Akim Demaille <akim@epita.fr>
9989 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
9990 * bin/autoheader.in (%symbol): Strip arguments of macros.

9998 * bin/autom4te.in (&parse_args): Die on unknown languages.
9999 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
10000 need for autoconf.
10001 Promote --include over --macrodir and other obsolete options.
10003 2001-08-31 Akim Demaille <akim@epita.fr>
10005 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

10007 * bin/autom4te.in ($autoconf): Pass --force.
10008 `print $out' doesn't print `$_' but `$out'.
10009 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10010 (autoheader): Pass --force since the test suite goes too fast for
10011 the time stamps.
10012 Adjust to the new autoheader messages.
10014 2001-08-31 Akim Demaille <akim@epita.fr>
10016 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
10017 Check the completeness of the #template.

10025 * bin/autoupdate.in, bin/autoheader.in: Adjust.
10026 Drop AC_MACRODIR dead for real.
10027 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10028 `autoheader: `config.hin' is created'.
10029 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10031 2001-08-31 Akim Demaille <akim@epita.fr>
10033 * bin/autoheader.in: Rewrite in Perl.
10034 * tests/autoheader: Adjust.
10036 2001-08-31 Akim Demaille <akim@epita.fr>
10038 * bin/autoconf.in (--include, -I): New option.
10039 Map --localdir, --autoconf-dir onto it.
10040 Forward autom4te's options instead of interpreting them.
10041 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10042 There is no such envvar since the inception of autom4te.cfg.
10043 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10044 * bin/autoupdate.in: Adjust, and perform more control.
10045 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
10046 * tests/autoconf: Dittowise.
10048 2001-08-31 Akim Demaille <akim@epita.fr>
10050 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10051 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10052 optionally `FILE'.
10053 Use -e, not -f, since /dev/null for instance is OK.
10054 (&parse_args): Adjust.
10055 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10057 2001-08-31 Akim Demaille <akim@epita.fr>
10059 * configure.ac: Also find tested executables in bin.
10060 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10061 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10062 installed peer executables, only PATH is allowed to resolve it.
10063 Pass `autoconf_dir' via options, not via invisible envvars.
10064 * lib/Autom4te/General.pm (&find_peer): Remove.
10065 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10066 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10067 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10068 find the executables for it.
10069 * tests/Makefile.am: Major cleanup. Too lazy to document...
10070 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10071 We only need PERL.
10072 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10073 indeed related to running the test suite, while passing
10074 --autoconf-dir and others is related to running non installed
10075 Autoconf executables. So don't do that, leave it to...
10076 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10077 * tests/autoscan: New.
10078 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10079 refer to library files: rely on --language.
10081 2001-08-29 Akim Demaille <akim@epita.fr>
10083 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

10086 2001-08-29 Akim Demaille <akim@epita.fr>
10088 * doc/autoconf.texi: Strip the @nodes.
10089 Suggested by Paul Eggert.

10092 2001-08-29 Akim Demaille <akim@epita.fr>
10094 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10095 Suggested by Paul Eggert.
10097 2001-08-29 Akim Demaille <akim@epita.fr>
10099 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10100 download in a tmp dir.
10102 2001-08-29 Akim Demaille <akim@epita.fr>
10104 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

10116 * bin/autoconf.in: Simplify and adjust.
10117 * tests/Makefile.am (AUTOMAKE): Use --set.
10118 * tests/atlocal.in: Adjust.
10119 * BUGS: distcheck and check are weak.
10121 2001-08-29 Akim Demaille <akim@epita.fr>
10123 * lib/autotest/general.m4: Use
10124 foo=`(command) 2>/dev/null`
10125 not
10126 foo=`command` 2>/dev/null
10127 (at-devnull): Rename as...
10128 (AT-devnull): this.
10129 (--clean): Remove AT-* files too.
10130 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10131 Reported by Nicolas Joly.

10165 * lib/autotest/general.m4 (AT_INIT): Log the command line.

10186 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
10187 `ac_top_builddir' to mimic Automake's vocabulary, which much more
10188 readable.

10190 * doc/autoconf.texi (Configuration Actions): Document the vars
10191 available in commands.
10192 Emphasize the risks of collisions in init-cmds.

10225 -> ac_dir).
10226 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
10227 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

10275 the name of the directory they're in, instead of the filename,
10276 since version.m4 is now in m4sugar, but m4_acversion must not be
10277 classified as an Autoconf macro.
10278 ($input_m4): Don't qualify the path to m4sugar.
10279 Rather, pass autoconf_dir to m4.
10280 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
10281 * tests/suite.at: Require 2.52c.

10295 of config.log on traps.

10297 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
10298 for config.status'.
10299 Open the log as soon as possible.
10300 Use the same log introduction as configure's.

10364 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
10365 * NEWS, README, README-alpha, TODO, tests/README: This package is
10366 `Autoconf', not `autoconf' (the executable).
10368 2001-08-20 Akim Demaille <akim@epita.fr>
10370 Info readers seem to need `Index' in the index node title :(
10372 * doc/autoconf.texi: Reverse the 2001-08-15 change which
10373 simplified index node names.
10375 2001-08-20 Akim Demaille <akim@epita.fr>

10417 2001-08-20 Akim Demaille <akim@epita.fr>
10419 Huh!?!?! There are still some user EOF tags used, which prevents
10420 their use in AC_CONFIG_COMMANDS for instance...
10422 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
10423 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
10424 `_CSEOF', or `_ATEOF', as appropriate.

10486 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
10487 `$0.log' as for projects where testsuite is in src, we'd have

10502 2001-08-17 Akim Demaille <akim@epita.fr>
10504 * doc/autoconf.texi: Work around Texinfo buglets.
10505 (Transformation Rules): One example is enough, users are expected
10506 to have their brains on. And BTW, use DESTDIR.
10507 (dvar): New macro. Use it.
10509 2001-08-17 Akim Demaille <akim@epita.fr>
10511 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

10517 * bin/autom4te.in: --normalize is a new option.
10518 * bin/autoconf.in: Use it.

10544 * doc/install.texi: Use @command.

10551 value.

10556 * Makefile.maint (CVS): New.

10559 (cvs-dist): depends upon it.
10561 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
10563 * tests/Makefile.am: Use a clean-local rule to remove
10564 autom4te.cache (it's a directory, not a file.
10565 * Makefile.am: Ditto (but maintainer-clean-local).
10567 2001-08-15 Akim Demaille <akim@epita.fr>
10569 * bin/autom4te.in (@m4_warning): New.
10570 (&handle_m4): Use it.
10571 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10572 warnings are issued at each run.
10573 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10574 is in the src tree.
10576 2001-08-15 Akim Demaille <akim@epita.fr>
10578 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
10579 don't waste time running `autoupdate --version' works.
10580 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10582 2001-08-13 Akim Demaille <akim@epita.fr>
10584 * doc/autoconf.texi (ma): Rename this index as...

10607 * doc/autoconf.texi, doc/install.texi: Add a copyright notice

10635 * tests/mktests.sh: Update year in copyright notice.
10637 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
10639 * tests/semantics.at (AC_C_BIGENDIAN): New test.
10641 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10643 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10644 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10645 * doc/autoconf.texi (C Compiler Characteristics): Update
10646 documentation for AC_C_BIGENDIAN.
10648 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10650 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10651 magic values from an object file when cross-compiling.
10652 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10654 2001-08-10 Akim Demaille <akim@epita.fr>
10656 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10657 effects.
10658 Suggested by Russ Allbery.
10660 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10662 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10663 current $prefix to the sub-configures.
10665 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10667 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10668 extension (needed on BeOS). Reported by Guido van Rossum.
10670 2001-08-09 Akim Demaille <akim@epita.fr>
10672 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10674 2001-08-07 Akim Demaille <akim@epita.fr>
10676 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10677 removed.
10678 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10679 No need to remove the files before and after the each test, before
10680 each test and at the end of the suite is enough.
10681 Display only the children `times', not the shell's.
10682 If the test failed or was skipped, at-times is not available.
10684 2001-08-07 Akim Demaille <akim@epita.fr>
10686 Always produce testsuite.log, including when there are no
10687 failures. This helps getting information on skipped tests, and
10688 duration of the tests. Err, implement the latter btw.
10690 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10691 Dump information on the first run of each test.
10692 (AT_CLEANUP): Create `at-times' containing the duration of the
10693 test group.
10695 2001-08-07 Akim Demaille <akim@epita.fr>
10697 The use of `dumpstat' revealed that `len' was used although it
10698 should not. m4_text_wrap was using it, but in the Autoconf world
10699 where it is legal. Hence (i) test M4sh in its own world, not
10700 Autoconf's, and (ii), ahem, fix the bug :)
10702 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10703 does not like `' instead of [].
10704 (AT_INIT): Forbid `^_?AT_'.
10705 And don't output such tokens.
10706 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10707 `script.as', and `autom4te.cache'.
10708 Remove `empty' and `macro' which are no longer used.
10709 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10710 * tests/m4sugar.at: Use it.
10711 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10713 2001-08-07 Akim Demaille <akim@epita.fr>
10715 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10717 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10719 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10721 2001-08-04 Akim Demaille <akim@epita.fr>
10723 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
