3 * doc/autoconf.texi: Some systematic minor improvements, as
4 follows. Use "makefile" when talking about makefiles
5 generally (which might be named "makefile" or "Makefile" or even
6 "foo.mk"), "Makefile" when talking about a specific makefile
7 called "Makefile". This unclutters the text from weird quotes
8 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9 values" rather than "@var{foo}s" and similar constructs containing
10 "}s". Use "Make rules" rather than "Makefile rules". Minor
11 English-language improvements. Change the prefix "sub-" to "sub"
12 and "re-" to "re".
13 Put blank lines around examples more consistently.
14 Avoid "rather" and "very" as intensifiers.
15 Avoid "will" as an auxiliary.
16 (Limitations of Make): Split this node into....
17 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
18 (Leading _ in Macro Names, Backslash-Newline-Newline):
19 (Backslash-Newline Comments, Long Lines in Makefiles):
20 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
21 (obj/ and Make, make -k Status, VPATH and Make):
22 (VPATH and Double-colon, $< in Explicit Rules):
23 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
24 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
25 New nodes, resulting from splitup of Limitations of Make.
26 All cross-references changed. Raise the top node from
27 a section to a chapter, and all subnodes accordingly.
28 Redo the introductory wording to match the new organization.
29 (Installation Directory Variables): Use an example that is
30 closer to what Autoconf actually does. Mention that VPATH's
31 value should not contain metacharacters or white space.
32 (Fortran Compiler): Fix a VPATH bug in an example.
33 (Leading _ in Macro Names): Mention that this problem is no longer
34 of practical concern.
35 (VPATH and Make): Reword the advice to make it clearer
36 that Autoconf and Automake support VPATH in non-GNU make, but
37 many packages have bugs in this area.
38 ($< in Explicit Rules): Refer to Build Directories rather
39 than using a (non-VPATH-safe) example.
40 (Automatic Rule Rewriting): Mention the sort of disaster that
41 can ensue with Solaris-style rule rewriting with VPATH.
43 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
45 * doc/install.texi (Compilers and Options): Weaken the
46 suggestion to use GNU make for VPATH builds.

52 in regular expression.
54 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
56 * doc/autoconf.texi (Installation Directory Variables):
57 Drop extra @samp from `@table @samp' item.
58 (Limitations of Usual Tools): Comment fix.
59 Do not nest @samp just to point to other table items.
60 (Writing testsuite.at) <AT_CHECK>: The second argument to
61 `@dvar' is already @samp'ed.
62 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
63 do not use @var in the second argument.
65 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
67 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
68 $as_shell.exe too. Problem reported by Andreas Buening in
69 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
71 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
73 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
74 `unused variable' compiler warning, for `-Wall -Werror'.
75 Reported by Jaap Haitsma in
76 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
78 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
80 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
81 case the compiler dumps core. Problem reported for
82 OpenServer 5.0.7 by Tim Rice in
83 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
84 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
85 Likewise.
87 2006-06-06 Tim Rice <tim@multitalents.net>.
89 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
90 "ERROR" only shows up in "make check" output if there is an
91 error.
93 2006-06-06 Eric Blake <ebb9@byu.net>
95 * tests/tools.at (automatically allowed tokens): Fix typo.
97 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
99 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
101 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
102 typically overflows on x86 CPUs, even though the C standard
103 requires otherwise.
105 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
107 * configure.ac (AC_INIT): Bump to 2.59e.
108 * NEWS: Update.

112 Version 2.59d.
114 * config/texinfo.tex: Sync from upstream.
116 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
117 seen, invoke libtoolize with `--ltdl' argument.
118 * lib/autom4te.in (Autoreconf-preselections): Adjust.
119 * NEWS: Update.
120 Suggested by Eric Blake.
122 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
124 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
125 reported by Ralf Wildenhues.
126 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
128 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
130 * THANKS: Update.
132 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

142 * tests/local.at (AT_CHECK_M4): New macro, almost identical
143 to...
144 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
145 AT_CHECK_M4.
146 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
147 `expout' as the last parameter.
148 * tests/tools.at: Adapt to the above change.
150 2006-06-04 Stepan Kasal <kasal@ucw.cz>
152 * doc/autoconf.texi (Limitations of Usual Tools): Correct
153 information about race-free implementations of mkdir.
155 2006-06-04 Eric Blake <ebb9@byu.net>
157 * bin/autoreconf.in (help): Document M4 environment variable.
158 * bin/autoconf.as (Usage): Likewise.
159 * bin/autom4te.in (help): Likewise.
160 * doc/autoconf.texi (autom4te Invocation): Likewise.
162 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
164 * NEWS: GNU make now recommended for VPATH builds.
165 Mention that some macros are now documented to be obsolescent.
166 * doc/autoconf.texi:
167 Prefer "current" to "modern" to describe
168 currently-used (albeit perhaps old-fashioned) hosts.
169 Mention which ancient features no longer need to be worried about.
170 setgid -> set-group-ID
171 setuid -> set-user-ID (these are the Posix terms)
172 Fix some misuses of "only".
173 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
174 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
175 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
176 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
177 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):

179 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
180 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
181 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
182 Mention that these macros are obsolescent.
183 (Installation Directory Variables): shall -> should
184 (File Descriptors): Mention that 0, 1, 2 might get reopened.
185 Mention that it's now safe to use 3 and 4.
186 (Limitations of Usual Tools): cp -r is now specified by Posix.
187 Omit longwinded and obsolescent discussion of cp -f.
188 Modernize discussion of expr, ls.
189 (Limitations of Make): Modernize discussion of VPATH builds.
190 Mention $? as a workaround in some cases.
191 * doc/install.texi (Basic Installation):
192 Mention "./configure; make; make install" first. Be more
193 specific about why this file is generic. Remove unnecessary
194 parens. Remove misleading "only". Remove obsolete advice
195 about csh. Don't say "configure" takes awhile; say it
196 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
197 and CC=c99 rather than CC=c89, as these are blessed by current
198 Posix. Recommend GNU make if doing a VPATH build.
200 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
202 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
203 examples involving shell prompts.
205 2006-06-02 Stepan Kasal <kasal@ucw.cz>
206 and Paul Eggert <eggert@cs.ucla.edu>
208 * doc/autoconf.texi (Here-Documents): Add details about the
209 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
210 use "here-documents" instead of "here documents".
212 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
214 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
216 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
218 * doc/autoconf.texi (File System Conventions): Warn about ":"
219 anywhere in directory names.
221 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
223 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
224 about quoting the case statement, just in case.
225 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
226 was fixed in ksh93g; reported by Ralf Wildenhues.
228 2006-05-31 Stepan Kasal <kasal@ucw.cz>
230 * doc/autoconf.texi (System Services): Do not document
231 overriding EXEEXT via ac_cv_exeext=ext.
232 (Particular Programs) <AC_PROG_MKDIR_P>:
233 Document that ${MKDIR_P} understands --.
234 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
235 comment.
237 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
239 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
240 argument with leading hyphen. Problem reported by Paul Eggert.
242 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
244 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
245 about quoting ac_try: quote all of it, if any of it seems suspicious.
246 This means we don't have to worry about ${ or sed any more.
247 Also, double-quote the case statement, to work around misuses via
248 underquoting as reported by Ralf Wildenhues in
249 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
250 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
251 undocumented and dangerous macro.
252 Problem reported by Ralf Wildenhues in
253 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
255 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
257 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
258 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
259 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
261 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
263 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
264 since evidently some packages rely on the old, broken behavior.
265 Problem reported by Ralf Wildenhues in
266 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
267 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
268 pre-2006-05-26 definitions, but leave in the comments that
269 these macros are dangerous and should not be used.
270 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
271 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
272 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
273 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
274 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
276 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
278 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
279 the use of 'tr', since this is our only use of 'tr'.
281 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
282 and Paul Eggert <eggert@cs.ucla.edu>
284 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
285 Don't assume 'grep' works on long lines, since AIX grep doesn't.
287 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
289 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
290 the output file in the `${datarootdir}' test.
292 2005-05-28 Stepan Kasal <kasal@ucw.cz>
293 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
295 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
296 mention of `datarootdir' in the input file(s), but literal
297 `${datarootdir}' in the output file, and we haven't warned yet,
298 then warn as well: the user may have (erroneously) used
299 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
300 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
301 * tests/torture.at (datarootdir workaround): Extend this test.
302 * NEWS: Update.
304 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
305 and Paul Eggert <eggert@cs.ucla.edu>
307 * doc/autoconf.texi (autoheader Invocation): The first argument to
308 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
309 alternatives and clear up the language a bit.
311 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
313 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
314 ac_config_guess, ac_config_sub, ac_configure.
315 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
316 Fix typo that prevented an unnecessary space from being removed.
317 Problems reported by Ralf Wildenhues in:
318 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
320 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
322 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
323 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
324 Don't use the term "thread-safe" to talk about mkdir race
325 conditions, since the problem is more a process than a thread
326 issue. Problem reported by Stepan Kasal in:
327 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
328 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
329 the test for 'install' more closely. Look at MKDIR_P first.
330 Look in the PATH, and at /opt/sfw/bin.
331 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
332 Don't bother to try mkdir -p, since we already check mkdir --version;
333 just look at the version number. (There's no easy way to check
334 for race-free implementations.)
335 * tests/tools.at (autoconf: subdirectories): Adjust to above
336 changes, since MKDIR_P now might end in "/mkdir -p".
338 * doc/autoconf.texi (autoheader Invocation): Mention that the
339 first arg of AC_DEFINE_UNQUOTED must be a literal.
340 Problem reported by Ben Pfaff in
341 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
343 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
344 * doc/autoconf.texi (Special Chars in Variables): New section.
345 (Preset Output Variables): Warn about special chars in CPPFLAGS.
346 (Installation Directory Variables): Quote $(datadir) better.
347 (Limitations of Builtins): Describe some of eval's trickiness.
349 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
350 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
351 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
352 in front of every arg, not just trailing args. Quote apostrophes.
353 (_AC_EVAL_ECHO): New macro.
354 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
355 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
356 removed.
357 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
358 exposed by quoting of eval argument. Put the command on line line
359 so it logs better.
360 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
361 (_AC_PATH_X, AC_PATH_X): Quote more safely.
362 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
363 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
364 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
365 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
366 Use eval more safely.
367 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
368 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
369 to be replaced.
370 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
371 lines, exposed by quoting of eval argument.
373 2006-05-26 Stepan Kasal <kasal@ucw.cz>
374 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
376 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
377 initialization of `ac_cv_exeext', do not override it if it was
378 already set, unless it was set to `no', for compatibility with
379 Autoconf-2.13, and comment this.
380 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
381 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
382 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
383 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
384 Document that this test may be overridden by setting
385 `ac_cv_exeext'.
387 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
389 Revert these two patches:
391 2006-04-06 Eric Blake <ebb9@byu.net>
392 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
393 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
394 2006-04-01.
396 2006-04-01 Stepan Kasal <kasal@ucw.cz>
397 Clean up _AC_COMPILER_EXEEXT* macros.
398 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
399 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
400 ac_file to the name of the default output file and call
401 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
402 initial `rm' of the candidate files...
403 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
404 the same list in subsequent `rm' calls, and for the temporary
405 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
406 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
407 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
408 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
409 no longer needed) by libtool. Make it a cache check.
410 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
411 copied here by mistake.
412 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
413 _AC_COMPILER_EXEEXT.
414 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
415 _AC_COMPILER_OBJEXT directly.
416 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
418 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
420 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
421 Fix description of how the buggy `sed' works.
423 2006-05-25 Noah Misch <noah@cs.caltech.edu>
425 Sync from Automake:
427 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
428 ENOLCK. Only mention `make -j' when applicable. Only raise
429 fatal errors when `make -j' is involved. Improve error message.
431 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
433 * doc/autoconf.texi (Here-Documents): We now know more about
434 the variable expansion in here documents bug.
435 Thanks to Tim Rice and Stepan Kasal.
437 * doc/autoconf.texi (Making testsuite Scripts): Add an example
438 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
440 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
442 * tests/autotest.at (Multiline command from M4 expansion):
443 No failure to be expected if the shell quotes newlines in
444 commands in the `set -x' output. Report by Tim Rice.
445 * THANKS: Update.
447 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
449 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
450 expansion in the here-documents used by config.status, as that
451 runs afoul of the Korn shell version M-12/28/93d bug described in
452 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
453 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
454 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
456 2006-05-23 Jim Meyering <jim@meyering.net>
458 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
459 Fix typo introduced with 2006-04-02 change. It reversed the sense
460 of the test.
462 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
464 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
465 ac_dB slightly, to save bytes in the script.
466 Max out at 50 lines, rather than 96; this is more likely
467 (though not guaranteed) to avoid obscure 'sed' failures.
469 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
471 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
472 `tr -d -' as bad option argument. Work around this by deleting
473 an unrelated character.
474 Report by Tim Rice <tim@multitalents.net>.
476 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
477 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
478 Stepan Kasal <kasal@ucw.cz>
480 * doc/autoconf.texi (Particular Programs): Do not promise that
481 we always prefer the GNU version of the program, and that we
482 search according to PATH; both rules can have exceptions.
483 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
484 AC_PROG_SED. Move descriptions of limitations
485 to the Limitations of Usual Tools section.
486 (Limitations of Usual Tools) <sed>: Mention script length
487 limitations with Solaris /usr/ucb/sed.
488 <grep>: Fix wording for empty alternative. Mention that -c and
489 -l should not be combined, and that -E and -F should not be
490 combined.
492 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
493 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
495 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
496 limits in Solaris 8 /usr/ucb/sed by testing a long script.
498 2006-05-22 Stepan Kasal <kasal@ucw.cz>
500 * doc/autoconf.texi (Defining Symbols): Literal parameter of
501 AC_DEFINE is now passed to m4_pattern_allow.
502 * NEWS: Mention that; likewise for AC_SUBST.
503 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
504 the parameter to m4_pattern_allow.
505 * tests/tools.at: Add a check for that.
507 2006-05-22 Stepan Kasal <kasal@ucw.cz>
509 * lib/autoconf/status.m4: Fix typos.
511 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
513 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
514 only the files that this macro generates.
516 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
518 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
519 the HP-UX sed limitation of 99 commands, labels do not count.
520 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
521 in the comment.
522 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
524 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
526 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
527 Import the following fix from coreutils:
529 2006-01-13 Jim Meyering <jim@meyering.net>
531 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
532 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
533 not double-quote uses of that variable, to accommodate the rare
534 case in which getmntent is available in none of the libraries
535 checked. This happens at least on FreeBSD 5.0.
537 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
539 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
540 ac_config_guess, ac_config_sub, and ac_configure, since evidently
541 some other programs unwisely rely on these undocumented vars.
542 But put in warning comments about them.
543 Problem reported by Ralf Wildenhues in
544 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
545 * NEWS: Document that these variables are intended to go away.
547 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
549 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
550 and set the language to C++ (analogous to the equivalent Fortran
551 tests).
553 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
554 * doc/autoconf.texi (C++ Compiler): Document it.
555 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
556 * NEWS: Update.
558 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
560 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
561 that caused config.status to generate 100-command sed scripts; the
562 portable limit is 99.
564 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
566 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
567 variable `ac_d' instead of `d' to avoid infringing namespace.
568 Report by Ralf Menzel.
570 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
572 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
573 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
574 * tests/tools.at (autoconf: subdirectories): New test, taken from
575 the corresponding problem report by Ralf Wildenhues in:
576 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
578 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
579 Quote some uses of shell variables if they might suffer unexpected
580 globbing. This doesn't fix all instances of quoting problems that
581 I found, just the easy ones that look safe.
582 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
583 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
584 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
585 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
586 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
587 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
588 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
589 Likewise.
590 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
591 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
593 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
595 * bin/autoreconf.in ($help): Reword according to the manual.
596 Suggested by Olly Betts.
598 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
599 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
601 * bin/autoreconf.in: Pass the directory argument to
602 `require_configure_ac'. Fix comment.
603 * tests/torture.at (Configuring subdirectories): Expose this.
604 Reported by Olly Betts.
606 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
608 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
609 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
610 Automake as follows:
612 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
613 `$configure_in' instead of `configure.in', to preserve
614 directory component.
616 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
618 * config/config.guess, config/config.sub, config/texinfo.tex,
619 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
621 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
623 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
624 test for C99 conformance; (bool) 0.5 is an integer constant
625 expression, but (bool) -0.5 is not. Problem reported by Fedor
626 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
628 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
630 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
631 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
632 Warn about obsolete install-sh files. Remove stray sentence
633 fragment and fix cross reference.
634 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
635 install -d; this undoes the 2006-05-10 change.
636 (MKDIR_P): Mark with AN_MAKEVAR.
637 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
638 that we don't require $INSTALL to be thread-safe. Move comments
639 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
640 of AC_PROG_INSTALL. Output a message saying that we're checking
641 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
642 MKDIR_P instead of AC_SUBST.
643 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
644 Special magic for MKDIR_P, too.
645 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
646 a dnl.
647 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
649 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
651 Sync from Automake, as follows:
653 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
654 * config/install-sh: Initialize IFS, so field splitting isn't
655 turned off later.
656 * config/mkinstalldirs: Likewise.
657 * config/missing: Remove superfluous quotes. Replace all uses of
658 `[' by `test', for consistency, and for..
659 * config/missing (sed_minuso, sed_output): New variables.
660 (autom4te, help2man, makeinfo): Use them. Unifies detection of
661 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
662 Fixes `missing' to detect `--output' for help2man. Fixes
663 PR automake/483. Report by Dennis J. Linse.
664 (autom4te): Document in `missing --help'.
666 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
668 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
669 * config/install-sh: Don't use 'path' to talk about file names,
670 as per GNU coding standards. Close a race condition reported by Ralf
671 Wildenhues and Stepan Kasal. There is still a race condition
672 on hosts that predate Posix 1003.1-1992, but we can't help this.
673 Don't mishandle weird characters like space on pre-Posix hosts.
674 Invoke mkdir at most once per dir arg on pre-Posix hosts.
675 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
676 AC_PROG_MKDIR_P from AS_MKDIR_P.
677 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
678 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
679 earlier editions are not (including Automake 1.8.3).
680 Do not suggest mkinstalldirs for thread-safety.
681 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
682 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
683 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
684 presence of special characters and race conditions.
685 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
686 in Autoconf's name space.
688 2006-05-10 Bruno Haible <bruno@clisp.org>
689 and Paul Eggert <eggert@cs.ucla.edu>
691 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
692 from Automake with minor changes.
693 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
695 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
697 * config/install-sh: Update to Automake CVS version, as follows:
698 2006-04-25 Stepan Kasal <kasal@ucw.cz>
699 * lib/install-sh: Simplify the expr implementation of dirname.
700 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
701 * lib/install-sh: Handle --, and diagnose unknown options.
703 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
705 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
706 `./autom4te' to create `./testsuite', since the `all' target
707 will ensure its presence, but `installcheck' should not create
708 the uninstalled wrappers.
710 * tests/torture.at (Unusual Automake input files): Skip if we
711 detect automake < 1.8.
713 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
715 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
716 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
717 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
718 * NEWS: Update.
720 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
722 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
723 munge (multiple) white space and other oddities.
724 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
725 single quotes in variable assignment.
726 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
727 and similar failures by adding multiple spaces, tabs, and other
728 special characters.
729 Report and different test suggested by Francesco Romani
730 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
732 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
733 single quotes, we only need to search for single quotes; this
734 both simplifies the search pattern, and makes us less
735 susceptible to `echo' variations for arguments not containing
736 single quotes.
737 (_AC_ARG_VAR_VALIDATE): Likewise.
739 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
741 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
742 `$*' and IFS concatenation issue with traditional shells and
743 bash-2.04. Report by Seanster@Seanster.com.
745 2006-05-03 Bruno Haible <bruno@clisp.org>
747 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
748 precisely which Mac OS X versions have the od problem.
750 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
752 * doc/autoconf.texi: Use @option systematically.
753 (Integer Overflow):
755 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
756 and Bruno Haible <bruno@clisp.org>
758 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
759 about 'od'.
760 (Integer Overflow): Mention the special case of integer division
761 overflow.
763 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
765 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
766 traditional shells like the Solaris one that do not use the
767 first IFS character for assembling `$*'.
768 Prompted by a related report from autoconf_bug@nro.ca.
770 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
771 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
773 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
774 Mention more problems with the -e option.
776 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
778 * NEWS: Typo.
779 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
781 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
782 in URLs to improve DVI formatted output (requires texinfo 4.6).
783 (System Services, Systemology, Shellology): Likewise.
784 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
785 output.
787 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
788 continuous text.
789 (Runtime): Fix macro argument names to match description:
790 `action-if-found' -> `action-if-true' and similarly.
791 (Obsolete Macros): Likewise.
792 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
793 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
794 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
796 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
798 * doc/autoconf.texi (Limitations of Make): Clean up markup.
800 * ChangeLog: Typo.
801 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
802 DVI output.
804 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
806 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
807 /bin/sh set unsorted output.
808 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
809 * tests/local.at: Likewise.
811 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
813 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
814 (Integer Overflow, Null Pointers, Buffer Overruns):
815 (Floating Point Portability, Exiting Portably): New sections.
816 (Writing Test Programs): Fix some langauge. Recommend exiting
817 with status 1, not merely nonzero. Clarify exit declaration.
818 (Run Time): Move C exit status stuff to new Exiting Portably section.
819 (Systemology): Mention Posix and levenez. Update v7 reference.
820 (Portable Shell): Mention the Posix shell.
822 2006-04-25 Stepan Kasal <kasal@ucw.cz>
824 * bin/autoconf.as (me): Replace by as_me.
826 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
828 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
829 since as_me isn't set yet.
831 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
833 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
834 a few minor bugs in this area.
836 * doc/autoconf.texi (Programming in M4sh): Comment out the
837 documentation of AS_BASENAME, for now.
838 (Shell Substitutions): Do not use AS_DIRNAME in an example.
839 (Limitations of Builtins) <basename>: Do not refer to
840 AS_BASENAME.
841 * bin/autoconf.as (me): Don't use AS_BASENAME.
842 (dir): Remove the unused variable.
843 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
844 AS_DETECT_REQUIRED. All uses changed.
845 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
846 All uses changed.
847 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
848 (AS_BASENAME): Use "basename --" to protect against leading "-".
849 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
850 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
851 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
852 (_AS_DIRNAME_PREPARE): Likewise.
853 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
854 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
855 (AS_DIRNAME): Use "dirname --".
857 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
859 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
860 of "run time" and "run-time" changed to "runtime", for consistency.
861 * lib/autoconf/fortran.m4: Likewise (in comment).
862 * lib/autoconf/functions.m4: Likewise.
863 * lib/autoconf/general.m4: Likewise.
864 * lib/autoconf/headers.m4: Likewise.
866 * doc/autoconf.texi (Run Time): Document the exit status situation
867 with more accuracy and detail.
869 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
871 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
872 Archive is not officially `GNU' any more. Update URL.
873 (Defining Directories): Likewise
874 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
876 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
878 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
879 newline from the `trap' code to finish `config.log'; the NetBSD
880 /bin/sh resets the exit status after an empty command, as
881 documented in doc/autoconf.texi.
882 Reported by Dalibor Topic <robilad@kaffe.org>.
884 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
886 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
887 Suggested by Bruno Haible.
889 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
891 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
892 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
893 Instead, just list the shells that we know work.
894 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
895 changed. Be more cautious about the _cv_ variable.
896 * tests/tools.at (Syntax of the shell scripts): Check the
897 _cv_ variable once, at first, to avoid an internal autoconf error
898 when sh -n does not work.
900 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
902 * lib/Autom4te/FileUtils.pm: Sync from Automake.
904 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
906 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
907 use ">&-" since we're only 99.999% sure that this is portable,
908 and since the MinGW bug is fixed in a different way.
909 * lib/autotest/general.m4 (AT_INIT): Likewise.
911 2006-04-16 Stepan Kasal <kasal@ucw.cz>
913 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
914 before opening config.log, to avoid hitting a bug on MinGW.
916 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
918 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
919 AS_MESSAGE_LOG_FD before reopening it onto the log file.
920 This works around a MinGW bug reported by Eric Paire.
921 Make sure that all writes to the log file append to it,
922 rather than possibly losing data.
923 * lib/autotest/general.m4 (AT_INIT): Likewise.
925 2006-04-14 Stepan Kasal <kasal@ucw.cz>
927 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
928 description.
930 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
932 * NEWS: Update.
934 * configure.ac (AC_INIT): Bump to 2.59d.
936 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
938 Version 2.59c.
940 * Makefile.maint (news-date-check): Do not require a leading `*'
941 before the release date in NEWS.
943 2006-04-12 Stepan Kasal <kasal@ucw.cz>
944 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
946 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
947 the instantiated file do not contain the string 'datarootdir'
948 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
949 @mandir@, replace the reference '${datarootdir}' by the value.
950 * tests/torture.at (datarootdir workaround): New test.
951 * NEWS: Advertise this temporary fixup.
952 Based on a patch by Bruno Haible, reported and analyzed by
953 Paul Eggert and Noah Misch.
955 2006-04-12 Eric Blake <ebb9@byu.net>
957 * tests/autotest.at (Debugging a failed test): Fix comment.
959 2006-04-12 Stepan Kasal <kasal@ucw.cz>
961 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
962 all the changes since 2006-04-07.
964 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
966 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
967 succeeded, but `ln -s file dir' failed, take care to remove the
968 leftover target before the next test, to prevent its spurious
969 failure; also make sure `ln file dir' works before selecting it.
970 Thanks to Keith Marshall for pointing this out.
971 * THANKS: Update.
973 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
974 assignments in `at_debug_args', so that we put them correctly
975 in the `run' script.
976 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
977 Reported by Eric Blake.
979 2006-04-11 Eric Blake <ebb9@byu.net>
981 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
982 top-level tests after micro-suite has been run. Used in...
983 (Debugging a successful test, Debugging script and environment),
984 (Debugging a failed test): ...these new tests. The first of these
985 is fixed by...
986 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
987 macro, split out from...
988 (AT_INIT): ...here, so that using -d also generates a run script.
989 Document that -d inhibits top-level logging.
990 * doc/autoconf.texi (testsuite Invocation): Document that -d only
991 inhibits top-level logging; debug scripts are created.
993 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
994 check.
995 * tests/autotest.at (Empty test, Empty check): New test to check it.
997 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
998 from gcc.
1000 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1002 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1003 the files if a problem appears. Make the empty *.at files
1004 read-only, too. Proposed by Ralf Wildenhues.
1006 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1008 * config/Makefile.am: Add comment to force updated Makefile.in.
1010 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1011 space only patch to this file, this patch causes the Makefile.in
1012 files that include freeze.mk to be updated, and thus have a
1013 newer time stamp again, which in turn makes a pristine CVS
1014 checkout have correct time stamps.
1016 * Makefile.maint (cvs-sv): New macro, to be used..
1017 (config.guess-url_prefix, config.sub-url_prefix)
1018 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1019 point to CVS text checkout of Gnulib files.
1020 (copyright-check): Bump current year.
1021 (announcement): Do not hard-wire `./announce-gen'.
1022 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1023 correctly.
1024 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1025 `chmod +x'.
1026 (wget_files): Update config.guess, config.sub, texinfo.tex by
1027 `wget-update', now that their URLs work again.
1029 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1031 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1032 Problem noted by Paul D. Smith.
1034 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1036 * doc/autoconf.texi: Remove unused words from word list.
1037 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1038 .x-sc_trailing_space: New files.
1040 * doc/standards.texi: Sync from gnulib.
1042 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1043 `LIBOBJDIR' as experimental.
1045 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1046 with a target directory; it's internally implemented as `cp'
1047 anyway, but since Autoconf advertises the possibility to use
1048 a target directory when LN_S is `ln -s', we need to find out.
1049 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1050 analyzed by Keith Marshall <keith.marshall@total.com>.
1052 * THANKS: Update.
1054 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1056 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1057 confdefs.h as-is. In general, if it has backslash-newline or the
1058 like, then it doesn't work either to sort or to remove empty
1059 lines.
1061 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1063 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1065 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1067 * lib/autom4te.in (Automake-preselections): Preselect
1068 _AM_SUBST_NOTMAKE.
1070 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1072 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1073 apostrophe within a single-quoted string, as this is the usual
1074 tradition and is easier to read than '"'"'. Don't rely on the
1075 shell treating "$/" like '$/'. Use a more-consistent indenting
1076 style for the trap.
1078 2006-04-09 Eric Blake <ebb9@byu.net>
1080 * tests/autotest.at (Backquote command substitution),
1081 (Multiline backquote command substitution): Remove mistaken
1082 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1083 applied...
1084 (Parenthetical command substitution, Multiline parenthetical
1085 command substitution): here.
1087 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1089 Import macros from gnulib (often changing their name).

1105 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1106 Gnulib section.
1107 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

1111 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
1112 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

1117 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1118 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1119 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1120 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1121 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1122 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1123 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1124 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1125 (Coding Style). Don't mention m4_expand_once.
1126 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
1127 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
1128 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.

1136 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
1137 Catch a bug in an HP-UX C compiler.
1138 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
1139 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

1143 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
1144 New macros.
1146 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
1147 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
1149 2006-04-08 Stepan Kasal <kasal@ucw.cz>
1151 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1152 of the warning introduced by the 2001-08-28 change.
1154 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
1155 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1157 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
1158 variables shall be overriden by the cache.

1160 that contains braces.
1162 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1164 Revert the patch from 2006-04-01 and only improve
1165 _AS_DETECT_BETTER_SHELL:
1167 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1168 skip nonexistent directories.
1169 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1170 only shell candidates which exist.
1171 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1172 * lib/autotest/general.m4 (AT_INIT): No need to give three
1173 parameters to _AS_PATH_WALK.
1175 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1176 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1178 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1179 distinguish m4sugar macros.
1180 * tests/tools.at (autoupdating with aclocal and m4_include):
1181 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1182 test case by Noah Misch <noah@cs.caltech.edu>.
1184 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1186 Revert my change from 2006-03-17, in other words:
1187 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1188 and DUALCASE=1.
1189 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1190 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1191 it is set.
1193 2006-04-07 Eric Blake <ebb9@byu.net>
1195 * doc/autoconf.texi (Programming in M4sh): Document that
1196 AS_MKDIR_P exits the script on failure.
1197 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1199 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1201 * config/elisp-comp, config/install-sh, config/mdate-sh,
1202 config/missing, config/mkinstalldirs: Sync from Automake.
1204 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
1205 from Automake.
1207 * doc/make-stds.texi: Sync from gnulib.
1209 2006-04-06 Eric Blake <ebb9@byu.net>
1211 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1212 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1213 2006-04-01.
1215 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
1216 Eric Blake <ebb9@byu.net>,
1217 Paul Eggert <eggert@cs.ucla.edu>,
1218 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1220 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1221 whether `set' quotes correctly: redirect stderr of the tested
1222 `set', and use a subshell, for Ultrix; use `sed' instead of
1223 `grep' for zsh `set' which may write binary output; match only
1224 at the beginning of a line, to avoid false positives.
1225 In order to avoid false positives by unrelated variables with
1226 multiline content, put the dump algorithm in a subshell and
1227 unset all variables containing newlines (except some which are
1228 special to the shell). Warn about cache variables that are
1229 unset.
1231 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1233 * config/config.guess, config/config.sub, config/texinfo.tex:
1234 Sync from upstream.
1236 * tests/mktests.sh: Reword comments.
1238 * tests/mktests.sh: Only skip internal macros starting with
1239 `_AC_' or `__AC_'. Noted by Stepan Kasal.
1240 Update exclusion lists for the test suite to this end:
1241 (AC_ARG_VAR): Do test this now.
1242 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1243 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1244 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1245 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1247 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1248 shell issue with double-quoted command substitutions of native
1249 commands.
1250 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
1251 Marshall.
1253 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
1254 no file matches the glob, discard the warning, set `nullglob'.
1255 (syntax-check): Likewise.
1256 (sc_cast_of_x_alloc_return_value): Likewise.
1257 (sc_cast_of_alloca_return_value, sc_error_exit_success)

1259 (m4-check): Likewise.
1260 (sc_system_h_headers): Do not print rule on execution.
1261 (sc_tight_scope): Do not fail for non-existing `src' directory.
1262 (sc_changelog): Skip the Copyright footer.
1263 * lib/autoconf/lang.m4: Remove trailing space.
1265 * lib/autoconf/status.m4: More replacements to
1266 <tab><space> where this makes sense.
1268 2006-04-06 Stepan Kasal <kasal@ucw.cz>
1270 * tests/Makefile.am (maintainer-check-posix):
1271 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1273 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1274 ac_config_<foo>s again, sometimes normalized, sometimes not.
1275 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1276 (AC_CONFIG_COMMANDS): Do not do so here.
1277 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1278 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1279 2005-07-25 rewrite. Noticed by Noah Misch.
1281 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1282 _AC_PRESERVE_HELP_ORDER, ...
1283 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1285 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1286 inside m4_expand_once; it is redundant.
1288 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1289 for --help from Cygnus `configure.'
1291 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
1293 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
1294 on a patch proposed by Ralf Wildenhues.
1296 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1298 * lib/autoconf/status.m4: Replace <space>''<tab> with
1299 <tab><space> where this makes sense.
1301 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
1302 Noah Misch <noah@cs.caltech.edu>
1304 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1305 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1306 * doc/autoconf.texi (Help Formatting): New node.
1307 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1309 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1311 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1312 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1313 lib/autoconf/types.m4, lib/autotest/general.m4,
1314 tests/mktests.sh, tests/torture.at: White space cleanup:
1315 remove some SPACE before TAB, or add quoting ('' or @&t@).
1317 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1319 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1321 2006-04-05 Eric Blake <ebb9@byu.net>
1323 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1324 empty test suite works.
1325 * tests/autotest.at (Empty test suite): Remove xfail.
1327 2006-04-05 Noah Misch <noah@cs.caltech.edu>
1329 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
1330 TAGS to ac_config_<foo>s.
1331 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1332 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1333 normalizing it, consistent it with previous releases.
1334 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1336 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1338 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1339 Use simplified args that Eric Blake originally suggested.
1341 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1343 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1344 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1345 Use 'comm' rather than N instances of grep; this also fixes a bug
1346 whereby substrings were incorrectly matched, causing us to not
1347 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1348 (exclude_list): Exclude empty macros.
1349 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
1351 Use awk rather than grep -E or egrep, to avoid
1352 portability problems with regular expressions containing newlines.
1353 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
1354 Switch from grep to awk syntax.
1355 (ac_exclude_script): Renamed from ac_exclude_egrep.
1356 (au_exclude_script): Renamed from au_exclude_egrep.
1358 2006-04-04 Noah Misch <noah@cs.caltech.edu>
1360 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences

1434 ac_file to the name of the default output file and call
1435 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1436 initial `rm' of the candidate files...
1437 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1438 the same list in subsequent `rm' calls, and for the temporary
1439 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1440 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1441 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1442 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

1522 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
1523 switch all of them on and of when necessary. Fixes the bug when
1524 m4sugar macros (e.g., m4_define) were expanded after the first
1525 automatic update (e.g., after AC_PREREQ or AC_INIT).
1527 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

1760 the obsolescent AC_HEADER_STDC.
1761 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs

1779 HP-UX sed is 99 commands, not 100.
1780 (_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
1781 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
1782 newline for portability.
1783 * tests/torture.at (Torturing config.status): Also test 100

2244 Stepan Kasal <kasal@ucw.cz>
2246 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2247 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2248 make its content writable before removing it. Remove an errorneous

2275 suggested by Ben Elliston. Handle weird characters correctly.
2277 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2279 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2280 calls, so that the final expansion of this macro is shorter.
2281 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2282 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2283 the cleanup there. Use AS_VAR_* macros, to be more general.
2284 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2286 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2288 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2290 2005-09-01 Stepan Kasal <kasal@ucw.cz>
2292 * doc/autoconf.texi (Configuration Headers): Add an index entry
2293 for AH_HEADER.
2295 2005-08-26 Pavel Roskin <proski@gnu.org>
2297 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
2298 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
2299 running xmkmf.
2301 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2303 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2304 The previous patch didn't work, so try a better one.
2306 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2308 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2309 in the example. Reported by Bruno Haible.
2310 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2311 "if $undefined_var;" succeeds with my shell.
2313 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2314 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2315 but change the m4_divert_text to m4_divert_once.
2317 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2319 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2320 Work around bug in Solaris /usr/xpg4/bin/awk.
2321 The bug is present in at least Solaris 8 through 10.
2323 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2325 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2326 some evil values and relying on the fact that $* concatenates the
2327 parameters by the first character from IFS.
2329 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2330 Stepan Kasal <kasal@ucw.cz>
2332 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2333 first header appears, define AH_HEADER.
2334 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2335 Update limitations about when to call AC_CONFIG_HEADERS.
2336 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2337 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2338 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2339 ``Configuration Actions''; fix their index entries.
2341 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2342 options correctly. Process N-M as M-N if M is smaller than N.
2343 Process ranges correctly so that N-N will run only N.
2344 Sort and uniquify the tests that will be run. If there is more
2345 than one test, reinsert the banners for the tests.
2346 * tests/autotest.at (Keywords): Unmark XFAIL.
2348 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2350 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2351 before passing the macro name to AH_TEMPLATE.
2353 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2354 now opens log after option processing; in particular, --version
2355 and --help do not touch config.log.
2357 * Makefile.maint: Revert the change from 2005-08-12.
2359 2005-08-22 Stepan Kasal <kasal@ucw.cz>

2369 Language cleanup.
2371 * doc/autoconf.texi (Defining Symbols, Changed Results):
2372 Prepend to LIBS, not append, in examples.
2374 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2376 When building in place, set srcdir="."; suggested by Tim Van Holder.
2378 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2379 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2380 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2381 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2382 does not mean "no --srcdir option".
2384 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2386 * tests/autoscan.at (autoscan): New file.
2387 * tests/suite.at: Use it.

2393 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2395 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2396 add "2>&1"; gzip 1.2.4 prints help on stderr.
2398 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2400 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2401 was pushdef'ed twice while popped only once. Push it only once.
2402 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2404 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2406 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

2411 * Makefile.maint: Update from Bison.
2413 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2414 "<tab>" in comment, so that the point is understandable.
2416 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2418 Rewrite substantial part of lib/autoconf/status.m4.
2419 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2420 and CONFIG_COMMANDS are not processed in four separate loops.
2421 Instead, there is one main loop. This alows that the common code
2422 is expanded only once, thus config.status (and configure) is smaller.
2424 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2425 the AC_LIST_FILES and cousins macros are no longer used.
2427 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2428 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2429 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2430 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2431 contain the initialization, nor the for loop, nor the associated
2432 commands; all these go to ...
2433 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2434 _AC_OUTPUT_CONFIG_STATUS.
2435 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2436 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2437 (_AC_OUTPUT_FILE): The creation of the sed script ...
2438 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2439 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2440 _AC_OUTPUT_MAIN_LOOP.
2441 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2442 _AC_CONFIG_COMMANDS): Use ...
2443 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2444 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2445 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2446 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2447 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2448 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2449 ... new macros.
2450 (_AC_CONFIG_UNIQUE): Update.
2451 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2452 Replaced by this ...
2453 (_AC_LIST_TAGS): ... new common macro.
2454 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2455 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2456 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2457 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2458 this didn't belong to the `config commands' section.
2459 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2460 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2461 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2462 to the `config commands' section either.
2463 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2464 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2466 ... and many changes to the comments nearby.
2468 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2469 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2470 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2471 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2472 (#define header templates): The comment at the top of the generated
2473 header now includes the name(s) of the source file(s).
2475 Several unrelated small changes:
2477 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2478 parameter to AC_DIAGNOSE.
2479 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2480 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2481 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2482 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2483 with AU::AC_OUTPUT.
2484 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2485 in AC_OUTPUT doesn't double-quote it either.
2486 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2487 parameters.
2489 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2491 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2492 versions of Portland Group compiler produce single- and double-quoted
2493 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2494 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2496 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2498 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2499 This is a corrected version of yesterday's patch.
2501 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2503 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2504 path, too; insert a "===" to emphasize the line.
2506 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2507 ac_cv_build_alias to ac_build_alias.
2508 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2510 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2511 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2512 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2513 (AC_ARG_VAR): ... here.
2514 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2515 target_alias.
2517 Keep a list of all precious variables and process them with one simple
2518 for loop, instead of expanding all commands, or, OTOH, complicated
2519 processing of output of "set".
2520 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2521 variable names in new macro...
2522 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2523 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2524 a loop to assign all ac_env_* and ac_cv_env_* variables.
2525 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2526 to INIT_PREPARE.
2527 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2528 its value to shell variable ac_precious_vars and call
2529 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2530 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2531 _AC_ARG_VAR_VALIDATE.
2533 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2534 and the AC_SUBSTs ...
2535 (AC_INIT): ... here.
2537 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2538 the ac_subst_files section in config.log.
2540 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
2542 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

2547 * tests/c.at (C keywords): Test AC_C_TYPEOF.
2549 Fix problems reported by Nicolas Joly.
2550 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
2551 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2552 They are generated by the Tru64 v5.1B shell.
2554 2005-07-05 Stepan Kasal <kasal@ucw.cz>
2556 Fix my changes from 2005-07-01; reported by Noah Misch.
2557 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2558 description, the macro now accepts only a single tag.
2559 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
2561 Fix cases when the varsions of Autoconf and Autotest don't match.
2562 Reported by Noah Misch.
2563 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
2564 at_top_builddir, for compatibility with older autotest.
2565 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2566 is not set, use at_top_builddir, for compatibility with older
2567 versions of autoconf.
2569 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2571 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2572 Problem reported by Patrick Welche.
2574 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2576 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2577 sed substitution command, so that we allow | in program prefixes
2578 and program suffixes. (& is a problem anyway; we're not fixing
2579 that here.)
2580 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2581 configure_input, top_builddir, srcdir, etc.
2582 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2583 PATH_SEPARATOR in AUTOTEST_PATH.
2585 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2587 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
2588 for loop over config.site files using `set', to allow
2589 directory names containing IFS characters.
2591 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
2593 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2594 directories with weird names. Apparently some people like living
2595 on the edge. However, improve the test that "pwd" actually does
2596 report a name for the working directory.
2597 * NEWS: Remove the claim that we test for funny chars in dir names.
2599 2005-07-01 Stepan Kasal <kasal@ucw.cz>

2611 about #include <config.h>.
2612 (Generic Functions): Mention the Gnulib project.
2613 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
2615 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2616 document to output the default config_* lists to config.status.
2617 Don't recognize option --file, if the functionality is not there.
2618 Likewise for --header; moreover, recognize --he and --h as shortcuts
2619 for --help in that case.
2621 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2622 matches the order of execution. No code changed.
2624 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2626 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

2641 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
2643 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
2644 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2645 (AC_SUBST): Call it.
2646 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2647 the directory specific variables; but don't call it for configure_input.
2649 2005-06-28 Derek Price <derek@ximbiot.com>
2651 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2652 addition.
2654 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2656 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2657 directory have inherent problems with special characters like spaces,
2658 due to limitations in Make syntax. Problem reported by Alexandre
2659 Duret-Lutz.
2660 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
2661 Also, fix Tru64 porting problem with shell patterns,

2672 Fix some more shell quoting problems. Prompted by a bug report
2673 from Justace Clutter.
2674 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
2675 variable into diagnostic. Make the diagnostic an error, not a warning,
2676 because we really don't support spaces and suchlike in dir names.
2677 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2678 Don't worry about backslashes in srcdir; it can't happen now.
2679 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
2680 Simplify ac_optarg handling.
2681 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.
2683 2005-06-22 Stepan Kasal <kasal@ucw.cz>

2689 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
2691 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
2692 that '\|' is not allowed in BREs; recommend using newline separated
2693 list of patterns instead of multiple -e options.
2695 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
2697 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

2701 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
2703 2005-06-21 Stepan Kasal <kasal@ucw.cz>
2705 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
2706 b, t, r, w commands require single space, while : cannot have any.
2707 (Special Shell Variables): Fix sed code this in the example.
2708 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2709 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2711 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2712 expand to the empty list. Don't use two pairs of m4_changequote,
2713 it's not necessary.
2715 2005-06-20 Derek Price <derek@ximbiot.com>
2717 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
2719 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
2721 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2722 * doc/autoconf.texi:
2723 Don't mention Solaris versions so much, if a
2724 problem is common to all extant versions of Solaris. Say "SunOS
2725 4" instead of "SunOS" for SunOS 4.
2726 (awk): Mention more of the limitations of traditional Awk.
2727 (cat): Don't talk about cat -v.
2729 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
2731 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
2732 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
2733 but the implementation is entirely different and is designed
2734 to be compatible with glibc strverscmp.
2735 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
2737 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
2738 on Mac OS X 10.4 reported by Peter O'Gorman in:
2739 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
2740 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
2741 Use shell builtins rather than 'expr', to work around expr bug.
2743 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
2745 * doc/autoconf.texi: "filesystem" -> "file system".
2746 "behaviour" -> "behavior".
2747 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
2748 * lib/autoconf/general.m4: Omit blank after ":" sed command,
2749 as per POSIX.
2750 * lib/m4sugar/m4sh.m4: Likewise.
2751 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
2752 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
2754 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
2755 (.x.1): Ignore the time stamp in the .TH line when deciding whether
2756 to update the man page. That way, we don't have to check in new
2757 man pages every month.
2759 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
2760 quotes and backslashes. Patch from Derek Price.

2765 AS_TR_SH.
2767 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
2769 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2770 -u, since it outputs chatter if the input files are the same.
2771 Problem reported by Ralf Menzel.
2773 2005-06-08 Derek Price <derek@ximbiot.com>
2775 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2776 renaming them since they are about to be redefined anyhow.
2778 2005-06-08 Derek Price <derek@ximbiot.com>
2780 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2781 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2782 Move m4_undefine to alphabetical order.
2784 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
2786 * README: Recommend GNU M4 1.4.3 or later.
2787 * doc/autoconf.texi (Introduction): Likewise.
2788 Reword to avoid some formatting glitches.
2789 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
2790 Clarify explanation of HP compiler bug.
2791 Redo example output tp match current CVS snapshot.
2792 Use @example.org in email addresses when the examples
2793 might get inadvertently cut-and-pasted into user code.
2794 Remove example of autom4te usage that doesn't seem to work now.
2795 Use modern AC_INIT (except when the example is meant to be
2796 shown with Autoconf 2.13).
2797 Update ksh info for Solaris 9 and later.
2798 KB -> kB.
2799 Modernize description of Automake versions a bit.
2800 Don't claim a future version of Autoconf is near.

2803 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2805 * doc/autoconf.texi: Add [] to examples, so that the manual
2806 follows its own advice about quoting better.
2807 Reword to avoid some formatting glitches.
2808 * doc/installt.exi: Reword to avoid some formatting glitches.
2810 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2811 Tru64 ksh pattern matching bug. Reported against Libtool by
2812 Albert Chin <libtool@mlists.thewrittenword.com> and
2813 Nicolas Joly <njoly@pasteur.fr>.
2815 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2817 m4_cdr of one-member list was [[]] (one-member list containing an
2818 empty string) instead of [] (an empty list. Callers were skewed to
2819 match this misbehaviour. As a consequence of this:
2820 - m4_foreach([x], [], [foo]) expanded to `foo', while
2821 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2822 This bug has been fixed:
2824 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2825 expand to an empty string; print error msg if called without
2826 an argument list.
2827 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2828 misbehaviour; handle [] and [[]] correctly.
2830 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2832 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
2833 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
2834 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
2836 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
2838 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2839 swallow records with more than 99 fields.
2840 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2841 parse the long line.
2843 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2845 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2846 swallow literals longer than 399. Reported by Ralf Wildenhues.
2847 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
2848 to workaround this limitation.
2850 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
2852 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
2853 to gfortran, and make these the first two compiler names
2854 checked (following the general autoconf preference for gcc).
2856 2005-06-03 Stepan Kasal <kasal@ucw.cz>
2858 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
2859 (DISTCLEANFILES): Remove $(check_SCRIPTS).
2860 (testsuite): Make sure autotest.m4f is up-to-date before using it.
2862 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
2864 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
2865 expression of unbounded size when processing the --list
2866 option. This runs afoul of a limit of 399 bytes per regular
2867 expression on AIX. Problem reported by Ralf Wildenhues.
2869 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
2871 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
2872 * doc/autoconf.texi (Particular Headers): Reword example
2873 for multiline stdbool replacement.
2874 (Setting Output Variables): Reword text a bit. Don't
2875 give all the details about |#_!!_#|.
2876 Reword description of line replacement.
2878 2005-05-31 Dan Manthey <dan_manthey@partech.com>
2880 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2881 now contain newlines, and substituted files must be referenced on
2882 a line alone; the sed scripts to substitute them are now very
2883 different.
2884 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
2885 commands can be put in a sed script portably.
2886 * doc/autoconf.texi (Setting Output Variables): Document above
2887 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
2888 use of multiline substitution.
2889 * tests/torture.at: No longer expect substitution of newline to fail.

2898 * tests/local.at: Don't attempt to check for negated character
2899 classes in shell scripts. The test was too brittle.
2901 2005-05-25 Stepan Kasal <kasal@ucw.cz>
2903 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
2904 * doc/autoconf.texi (Limitations of Builtins): Document this
2905 limitation.
2907 2005-05-24 Stepan Kasal <kasal@ucw.cz>
2909 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
2910 common code; used in many places in the tree.
2911 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
2912 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
2914 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
2916 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
2917 messages when ac_unique_file is not found.
2918 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
2919 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
2920 commands, for consistency with AC_MSG_ERROR and such.
2922 * bin/autoconf.as: Make more use of "shift 2" in option processing.
2924 * bin/Makefile.am: Merge the two rules for creating scripts.
2926 2005-05-23 Stepan Kasal <kasal@ucw.cz>

2932 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2934 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
2935 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
2936 (ac_top_builddir): ... this ...
2937 (ac_top_build_prefix): ... to this; the old name is also kept, for
2938 backward compatibility.
2939 (ac_top_builddir_sub): New variable, without the trailing slash,
2940 always nonempty.
2941 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
2942 * doc/autoconf.texi (Configuration Actions): Rename
2943 ac_top_builddir to ac_top_build_prefix.
2944 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
2945 at_top_builddir to at_top_build_prefix.

2948 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2950 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
2951 of confdefs.h .
2953 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2955 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2956 argument to m4_foreach. I guess it was necessary in the past,
2957 but I think it's a no-op now.
2959 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2961 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2962 ``cat <<_ACEOF'' commands to one.
2963 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
2964 * lib/autoconf/status.m4: On various places, use expr instead of
2965 ``echo|sed.''
2966 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
2967 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2968 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2969 a range.
2970 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2971 the wrong patterns between ``case'' and ``esac.'' The previous
2972 code had false positives.

2976 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
2977 as on 2005-05-02.
2978 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
2979 Mention LIBOBJDIR.

3041 quoting rules. Problems noted by Stepan Kasal.
3042 Also, throughout this document, be more careful about white space.
3043 "blank", "white space", and "space" all have different meanings
3044 and we should be careful to say what we mean.
3046 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3048 Fix C++ related problems reported by Werner Lemberg.
3049 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

3095 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3096 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3097 comment and reduce m4_default([foo], []) to [foo].
3098 (m4_strip): Update the explanation.
3100 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3102 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3103 Remove core.conftest.* too; it's generated by Tru64 5.1.
3104 Problem reported by Jennis Pruett.
3105 * lib/autoconf/functions.m4
3106 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3107 Don't bother to remove core files; AC_RUN_IFELSE should do that
3108 for you.
3110 2005-04-19 Stepan Kasal <kasal@ucw.cz>

3180 ac_pwd, and quote srcdir.
3181 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3183 * doc/autoconf.texi: Fix some systematic formatting problems.
3184 ".)" needs a following @: if not at the end of a sentence, and
3185 similarly for "!)". "etc." should be preceded by a comma.
3186 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3188 2005-03-22 Bruno Haible <bruno@clisp.org>
3190 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3191 argument is often called 'build-aux'.
3193 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3195 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3196 macro AC_TRY_LINK is obsolete.
3197 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3198 `AC_CONFIG_FILES'.
3200 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3202 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3203 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3204 from a Common Lisp's `cl'.
3205 (AC_PROG_CXX): Behave according to the documentation: don't
3206 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3207 make the variable CCC precious; use `cl.exe', not `cl'.
3209 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3210 Alexandre Duret-Lutz <adl@gnu.org>
3212 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3213 /dev/null, as "configure" shouldn't read stdin, and this insulates
3214 us from problems (e.g., when testing for "cl"). Also, do this
3215 redirection before invoking "hostname" or "uname", and keep the
3216 original input stream available via...
3217 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3218 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3219 bother with "</dev/null" since it's now done at the top of
3220 'configure'.
3221 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3222 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3223 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

3228 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3230 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3231 newline if neither \c nor -n work, as that would output two
3232 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3234 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3236 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3237 This causes that any required macros inside will get before the if.
3238 * doc/autoconf.texi (autom4te.cache): A typo.
3240 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3242 Undo previous change, except keep the change to
3243 lib/autoconf/programs.m4 that replaced grep with shell
3244 pattern-matching. This is because net-snmp configure reads stdin.
3245 Reported by Noah Misch.
3247 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3249 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3250 from /dev/null, as "configure" shouldn't read stdin, and this
3251 insulates us from problems (e.g., when testing for "cl").
3252 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3253 before invoking "hostname" or "uname".
3254 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3255 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3256 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3257 "</dev/null" since it's now done at the top of 'configure'.
3258 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3259 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3260 Also, replace grep with shell pattern-matching, to save a process.
3262 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3264 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3265 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3266 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3267 compiler.
3269 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3271 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3272 grep -q isn't portable. Improve grep -s explanation.
3273 Problem reported by Dan Manthey.
3275 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3277 * doc/autoconf.texi (Special Shell Variables): Clarify
3278 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3280 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3282 * doc/autoconf.texi: Use @acronym for DJGPP.
3283 Fix some @code's that should have been @env's, and vice versa.
3284 Sort environment variable names.
3285 Mention that shells no longer inherit IFS.
3286 Don't recommend PATH_SEPARATOR=';' so strongly.
3287 Mention that $RANDOM might expand to the empty string.
3288 "symlink" and "soft link" -> "symbolic link".
3289 Improve mktemp description (reported by Bruno Haible).
3291 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3293 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3294 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3295 Likewise.
3296 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3297 Likewise.
3299 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3301 * NEWS: Mention AT_COPYRIGHT.
3303 * tests/local.at (AT_CMP): Use diff directly on input files rather
3304 than copying them.
3306 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3307 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3309 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3310 and Paul Eggert <eggert@cs.ucla.edu>
3312 * tests/autotest.at (Empty test suite): New test.

3317 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3319 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3320 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3321 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3322 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3323 (Standard regular expressions): New test.
3324 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3325 excess test name quoting.
3326 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3327 CPPFLAGS to `configure' instead of setting it in `configure'.
3329 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3330 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3331 on some platforms.
3333 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3334 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

3342 * tests/c.at (Extensions): Do not exit early.

3362 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3364 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3365 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3367 Try not to generated lines of unlimited length, as POSIX places a
3368 2047-byte limit on line length of portable text files.
3369 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3370 Use newline as a separator, not space.
3371 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
3372 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
3373 space.
3375 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3377 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
3378 as_func_*. Add test to check whether positional parameters
3379 are restored after function return.
3381 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
3383 * doc/autoconf.texi (Special Shell Variables): Mention _,
3384 BIN_SH, DUALCASE. Say that variables other than "status" are safe
3385 if they contain a lower-case letter. The DUALCASE problem was
3386 reported by Ralf Wildenhues.
3388 * bin/autoconf.as: Don't exit with status 0 after write failure
3389 with --help or --version.
3390 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

3396 Unicos 9 sed limitations.
3397 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

3399 Fortran 95 (newer Crays).
3401 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
3403 * man/Makefile.am (.x.1): Go back to the simple solution, but take
3404 care to echo the commands, so the user knows what's going on.
3405 Modified from a suggestion by Stepan Kasal.
3407 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

3415 Based on a proposed patch by Ralf Wildenhues.
3417 * man/Makefile.am (.x.1): Make sure the required generated files
3418 are up to date. Problem and original solution proposed by Stepan Kasal.
3419 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
3420 implicit-man-prerequisites): New rules, used by the above.

3426 2005-01-29 Stepan Kasal <kasal@ucw.cz>
3428 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3429 Update the long comment explaining it.
3431 m4_require no longer writes an ``is required by'' line to the
3432 execution stack. It contains only one bit of non-redundant
3433 information: that the macro was required, not called. And even
3434 this bit is useless in most situations: have you ever met a macro
3435 which both calls and requires the same macro?
3437 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3438 (_m4_defun_pro_outer): ... only via this macro, for the outermost
3439 macro.
3440 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
3441 (m4_expansion_stack_pop): Remove the misplaced comment.
3442 (m4_require): Don't put the ``is required by'' line to the
3443 execution stack; slightly improve the out-of-a-defun error message.
3444 (_m4_divert_grow): New macro, counter for the temporary diversions.
3445 (_m4_require_call): Use it.
3446 * tests/m4sugar.at (m4_require): Expect output without the
3447 ``is required by'' messages.
3449 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3451 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3452 rather than x for expr.
3454 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3455 this is safe.
3456 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
3457 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

3466 * doc/make-stds.texi, doc/standards.texi: Update from masters.
3467 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
3468 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
3469 from masters, so that FileUtils.pm's update_file provide --force
3470 support.
3471 * bin/autoheader.in: Pass $force to update_file so that
3472 config.h.in is always recreated when --force.
3474 2005-01-24 Stepan Kasal <kasal@ucw.cz>
3476 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
3478 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3480 * doc/autoconf.texi (Limitations of Builtins): Clarify that
3481 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
3483 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3485 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3486 Warn about newline stripping in `` and $(). Update Solaris
3487 version to 9.
3488 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3489 X insulates us from future changes to Posix.
3490 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3491 stripping.
3493 2005-01-19 Stepan Kasal <kasal@ucw.cz>
3495 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
3496 you cannot use AC_DEFINE to define macros containing `[' or `]'.
3498 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
3500 * doc/autoconf.texi (Limitations of Usual Tools): Document bug

3511 ulongval to be static, to avoid unwanted GCC warning. Problem
3512 reported by Michael Jennings via Daniel Reed; see
3513 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
3515 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3517 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
3518 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
3519 datadir, infodir, and mandir. Adjust argument parsing code.
3520 (_AC_INIT_HELP): Update help text.

3522 new variables.
3524 2005-01-04 Noah Misch <noah@cs.caltech.edu>
3526 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
3527 not seem to work, assume it does set $(MAKE).
3528 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
3530 2005-01-03 Stepan Kasal <kasal@ucw.cz>
3532 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

3538 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
3539 (_m4_divert_n_stack): New macro; the expansion is
3540 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
3541 otherwise.
3542 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3543 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3544 stored in _m4_divert_diversion or _m4_divert_dump.
3545 (m4_divert_pop): When the parameter is given, compare the symbolic
3546 name with the last diversion pushed on the stack. Previously, the
3547 current diversion was compared with the numeric value of the
3548 diversion given as the parameter.
3549 (m4_require): If the macro hasn't been expanded yet, call ...
3550 (_m4_require_call): this new macro.
3552 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3554 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

3583 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
3584 signals that the package uses Automake; a `Makefile.am' is typical but
3585 not essential. Reported by Magnus Therning.
3586 * tests/torture.at (autoreconf.): New banner.
3587 (autoreconf and non-AC configure): Rename to `Non-Autoconf
3588 AC_CONFIG_SUBDIRS'.

3977 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

4083 * lib/autom4te.in (Automake-preselections): Preselect
4084 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4086 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4088 * lib/autom4te.in (Automake-preselections): Preselect
4089 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4090 trace them.
4092 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4094 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4095 Tru64.
4096 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4097 Document problem with "`""`" in pdksh POSIX mode.
4099 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4101 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4102 with pdksh, too. Problem reported by Patrick Welche via
4103 Gary V. Vaughan.
4104 * doc/autoconf.texi (Shellology): Note that set -o posix is
4105 useful for pkdsh, too.
4107 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4109 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4110 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4111 Don't fail if ENV or BASH_ENV is readonly.
4112 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4113 etc. are read only. Problem reported by Ludovic Courtes.
4115 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4117 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4118 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4119 (trivial change)
4121 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4123 * doc/autoconf.texi (File System Conventions): Warn about
4124 names like "aux". Problem reported by Eric Blake.
4126 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4127 by zero instead of array size, so that we can use any arithmetic
4128 constant expression (instead of requiring an integer constant
4129 expression). This allows us to test expressions like DBL_MAX <
4130 LDBL_MAX, which didn't conform to the C standard using the old
4131 method.
4132 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4133 now that we can do floating-point tests at compile time.
4135 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4137 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4138 and LDBL_EPSILON, as the resulting expression isn't an
4139 integer constant expression and violates the C standard.
4140 Problem reported by Nelson H. F. Beebe. Also, check
4141 for "L" suffix, and check that long double doesn't have
4142 worse range or precision than double, that mixed-mode
4143 arithmetic doesn't generate a diagnostic, that double
4144 constants fit in long double.
4146 2004-06-03 Kevin Ryde <user42@zip.com.au>
4148 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4149 malloc(0) and realloc(NULL,size).
4151 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4152 Bob Proulx.
4154 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4156 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4157 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4158 by Jim Meyering.
4160 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4162 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4163 can be rewritten using if-then-else. Suggested by Bruno Haible.
4165 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4167 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4168 Problem reported by Stepan Kasal.
4170 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4172 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4173 change). Patch reported by Ralf Wildenhues in
4174 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4176 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4177 function F exists if the compiler and linker let you compile an
4178 expression like (F != 0). Recent versions of GCC optimize away
4179 the reference to F in that case, since every function address must
4180 be nonzero, so the link succeeds even if F does not exist.
4181 Problem reported by Manu in
4182 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4184 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4185 "Unix". Many uses changed.
4186 (Limitations of Builtins): Explain better why the ! command isn't
4187 portable.
4189 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4191 * lib/autom4te.in (Automake-preselections): Preselect
4192 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4194 2004-05-19 Kevin Ryde <user42@zip.com.au>
4196 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4197 referencing AC_FUNC_STRERROR_R.
4199 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4200 note pessimistic assumption when cross compiling.
4202 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4204 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4205 (until 2004) invoked subcommands with sh -e, contra POSIX.
4206 Reported by Kevin Ryde.
4208 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4210 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4211 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4212 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4213 `test -f " /usr/bin/grep"', which _always_ failed.
4214 (AC_PROG_SED): Ditto bogus PATH fix.
4215 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4216 requires that grep correctly supports _multiple_ `-e' options, rather
4217 than stating only that grep should accept `-e'.
4219 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4221 Port to C99, which requires that 'exit' be declared.
4223 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4224 to ensure that stdlib.h is included.
4225 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4226 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4227 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4228 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4229 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4230 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4231 when using 'exit' in a test; C99 requires that 'exit' be declared.
4233 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4235 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4236 now prefers 'grep' implementations that accept -e.
4237 (Limitations of Usual Tools): Describe problems of traditional
4238 egrep and fgrep with long input lines, and of traditional grep
4239 with -e.
4240 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4241 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4242 All callers changed. Append /usr/xpg4/bin to the PATH, for
4243 Solaris.
4244 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4245 the user with complaints about multiple -e options.
4246 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4247 Define it with AC_PROG_GREP.
4248 * configure.ac (AC_PROG_GREP): Add.
4249 * lib/freeze.mk (GREP): New macro.
4251 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4253 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4254 a possible candidate only after all others fail, rather than
4255 consulting it first. This improves backward compatibility by
4256 better reflecting the way shell selection occurred in previous
4257 versions of Autoconf, and should help to avoid triggering latent
4258 problems in other packages, such as the one in Automake where zsh
4259 is not handled robustly:
4260 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4261 Although it is not Autoconf's responsibility to work around
4262 problems in Automake, it nevertheless makes sense to avoid
4263 introducing unnecessary incompatibilites.
4265 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4266 Gary V. Vaughan <gary@gnu.org>
4268 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4269 how deeply nested we are when a suitable tool is found, set the
4270 ac_path_TOOL_found flag.
4271 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4272 nested we are in this macro. Break out of all 3 nested loops if
4273 ac_path_TOOL_found is set.
4275 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4277 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4278 of the _AS_PATH_WALK loop too if GNU flavor is found.
4280 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4282 * doc/autoconf.texi (Limitations of Make): Update documentation
4283 for `$<'. New entry `Long lines', based on a report from Simon
4284 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4285 paragraph about DJGPP, based on a mail from Richard Dawe.
4287 2004-04-20 Paul Eggert <eggert@twinsun.com>
4289 * tests/c.at (C keywords): Don't assume that GCC supports
4290 "restrict" and "inline", as sufficiently-old GCC versions do not
4291 (also, GCC configured to be in pedantic C89 mode does not).
4292 Problem reported by Sumit Pandya in:
4293 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4295 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4296 consider -g to work if it generates warnings when plain compiles
4297 don't. Problem reported by Braden McDaniel in:
4298 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4300 * doc/autoconf.texi (Slashes): New section, to document a problem
4301 reported by Jim Meyering in:
4302 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4304 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4305 linker output files before linking, to work around IRIX 6 linker bug.
4306 Problem reported by Rainer Orth in:
4307 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4309 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4311 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4312 best tool so far counter rely on the tool path variable name to
4313 avoid checks for one tool being affected by the results of running
4314 the length check on a previous tool.
4316 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4317 match expression argument, as different greps have different
4318 regular expression flavours.
4319 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4320 literals.
4321 (AC_PROG_EGREP): Pass 'EGREP$'.
4322 (AC_PROG_GREP): Pass 'GREP$'.
4324 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4326 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4327 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4329 2004-03-29 Paul Eggert <eggert@twinsun.com>
4331 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4332 Types, Specific Compiler Characteristics, System Services,
4333 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4334 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4335 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4336 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4337 Likewise.
4338 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4339 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4340 AC_TYPE_OFF_T): Likewise.
4341 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4342 Likewise.
4344 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
4345 pacify libtool 1.5.2. Fix quoting problems in sed command.
4347 2004-03-28 Paul Eggert <eggert@twinsun.com>
4349 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4350 now defines HAVE_DECL_TZNAME if it is declared, when
4351 HAVE_STRUCT_TM_TM_ZONE is not defined.
4352 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4353 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4354 for HAVE_TZNAME.
4356 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4358 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4359 superfluous backslashing of quotes (") in sed expressions;
4360 thanks to Paul Eggert.
4362 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4364 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4365 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4366 H. F. Beebe for the bug report.
4368 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4370 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4371 quoted -cmdline argument in Portland Group compiler (bug
4372 reported by Jeffrey J. Barteet).
4374 2004-03-25 Kevin Ryde <user42@zip.com.au>
4376 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4377 (Run Time): ... here, where it's now mentioned.
4379 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
4381 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4382 inherits from language Autoconf-without-aclocal-m4.
4383 (Customizing autom4te): Adjust example; the cache must now be
4384 disabled for language Autoconf-without-aclocal-m4.
4386 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
4387 Nathanael Nerode <neroden@twcny.rr.com>

4398 AC_CHECK_TOOLS.
4399 (Specifying Names): Document the reason for these future
4400 behavioral changes.
4401 * tests/mktests.sh: Do not generate tests for the
4402 new macros.
4403 * NEWS: Document these changes.
4405 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4406 they make TeX hang up.
4408 2004-03-15 Paul Eggert <eggert@bogus.example.com>
4410 * NEWS: New macro AC_CHECK_ALIGNOF.
4411 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4412 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4413 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4414 vowel.
4415 (AC_CHECK_ALIGNOF): New macro.
4416 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
4417 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
4418 those for sizeof.
4420 2004-03-03 Paul Eggert <eggert@twinsun.com>
4422 * bin/Makefile.am (edit): Don't use $< in a context where
4423 POSIX doesn't require support for it. Use $@.in instead.
4424 Problem reported by Anthony N. Frasso in
4425 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4426 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4428 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4430 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4431 from the next generation of Libtool.
4432 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4434 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4436 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

4454 AC_SUBST provides no portable way to escape literal newlines.
4456 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4457 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4458 Darwin uses -lcrt2.o and there's little point to cataloging all
4459 the system variants. Partial fix reported by Andreas Waechter in:
4460 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4461 for bug reported by Nelson H. F. Beebe in:

4474 refer to the correct file.
4475 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4476 the behavior of the third argument.
4477 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4478 correctly the behavior of the third argument. Document
4479 what the three macros that AU_DEFUN defines do. Fix
4480 warning message when the third argument includes $0
4481 (reported by Alexandre Duret-Lutz).
4483 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4484 Eric Sunshine <sunshine@sunshineco.com>
4485 Paul Eggert <eggert@twinsun.com>
4487 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4488 (AS_INIT): Output shell initialization there. Removed optional
4489 parameter. Expand _AS_SHELL_FN_SPY.
4490 (AS_INIT_WITH_SHELL_FN): Removed.
4491 (_AS_SHELL_FN_SPY): New macro.
4492 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4493 macros.
4494 (AS_SHELL_SANITIZE): Remove loop to find better shell
4495 and documentation for the parameter.
4496 (_AS_DETECT_BETTER_SHELL): Move it here.

4498 (_AS_RUN): Move it here, support testing with eval.
4499 (AS_REQUIRE_SHELL_FN): Require shell functions when
4500 it is used.
4501 (_AS_LINENO_WORKS): Put around braces, we do not
4502 trigger the bash bug anymore.

4504 use AS_INIT_WITH_SHELL_FN.
4505 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4507 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

4511 is broken.
4512 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
4513 (AU_DEFUN): Honor the third parameter, create autoupdate
4514 macros with AU_DEFINE.

4535 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

4537 the 2003-05-22 change, which removed the older years from the list.
4538 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4540 2004-01-27 Gary V. Vaughan <gary@gnu.org>
4541 Albert Chin-A-Young <china@thewrittenword.com>

4545 possible.
4546 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4547 AC_PROG_GREP.
4548 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4549 egrep and fgrep respectively if $GREP -E/-F don't work.
4550 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4551 _AC_PROG_GREP, and AC_PROG_SED.
4552 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4553 longest input length accepted by a command.
4554 (AC_PROG_SED): Use it.
4555 * doc/autoconf.texi (Particular Programs): Document the changes.
4556 * NEWS: Updated.
4558 2004-01-27 Paul Eggert <eggert@twinsun.com>
4560 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

4562 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
4563 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
4565 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4566 bin/autoconf.in, config/Makefile.in, config/config.guess,
4567 config/config.sub, config/install-sh, config/mdate-sh,

4582 2004-01-26 Paul Eggert <eggert@twinsun.com>
4584 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4585 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4586 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4587 not <inttypes.h>. Problem reported by Tim Mooney in
4588 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4589 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4590 Likewise.
4592 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4593 otherwise "make check" fails because it forbids cmp (I guess
4594 because cmp treats files as binary on DOS-like systems).
4596 * tests/mktests.sh: Update copyright date to 2004, since some tests
4597 have changed in 2004.
4599 2004-01-23 Gary V. Vaughan <gary@gnu.org>

4602 non-truncating sed or gsed program in PATH.

4605 * NEWS: Updated.
4607 2004-01-15 Paul Eggert <eggert@twinsun.com>
4609 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4610 -std1 disables some useful extensions on Tru64. Problem reported
4611 by N. Lichtmaier in
4612 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4614 2004-01-14 Paul Eggert <eggert@twinsun.com>
4616 * doc/autoconf.texi (Programming in M4sh): Document that
4617 AS_MKDIR_P succeeds if the destination is a symbolic link
4618 to an existing directory.
4619 (Limitations of Usual Tools): Note that mkdir -p might not
4620 succeed on symlinks to directories.
4622 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4624 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4625 * bin/autoheader.in: Grammar fix in message.
4626 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4627 Test for dir before calling mkdir -p. (trivial changes)
4629 2004-01-13 Eric Blake <ebb9@byu.net>
4631 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4632 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4634 2004-01-10 Jim Meyering <jim@meyering.net>
4636 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4638 2004-01-09 Paul Eggert <eggert@twinsun.com>
4640 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4641 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4642 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4643 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4644 AC_COMPILE_IFELSE, since we now assume our caller invokes
4645 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4646 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4647 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4648 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4650 2004-01-07 Paul Eggert <eggert@twinsun.com>
4652 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4653 `"'...'"`, as it's confusing (and I suspect it may not work on
4654 some platforms). The code was incorrect anyway, as it assumed
4655 that \$ evaluated to itself in that context. Reported by
4656 Alexandre Duret-Lutz.
4658 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4660 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
4661 and _LT_AC_TAGCONFIG.

4665 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4666 example, and add more examples. Reported by Eric Sunshine.
4668 2004-01-05 Paul Eggert <eggert@twinsun.com>
4670 * doc/autoconf.texi (Limitations of Usual Tools):
4671 Remove warning against "rm -fr" introduced yesterday; it
4672 was a false alarm.
4674 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4675 autoscan, autoupdate, ifnames): Don't use chmod -w.
4676 * lib/Makefile.am (autom4te.cfg): Likewise.
4677 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4678 "chmod -w".

4683 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts

4686 2004-01-04 Paul Eggert <eggert@twinsun.com>
4688 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4689 Use "rm -f" to remove conftest.sed, not plain "rm".
4690 Bug reported by David Relson in
4691 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4693 * Makefile.am (autom4te-update):
4694 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4695 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4696 * doc/autoconf.texi (Guidelines): Likewise.
4697 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

4702 * tests/Makefile.am (clean-local): Likewise.
4703 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
4704 srcdir): Likewise.
4705 * doc/autoconf.texi (Limitations of Usual Tools):
4706 Warn against "rm -fr".
4708 2004-01-03 Paul Eggert <eggert@twinsun.com>
4710 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4711 -c -o might not work. From a suggestion by Kevin Ryde.
4712 (C Compiler, Generating Sources, Limitations
4713 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4714 Don't put '-o' after non-options, as POSIX doesn't allow this.
4715 Mention that cc's name might be gcc or c89 or whatever.
4717 2004-01-04 Kevin Ryde <user42@zip.com.au>
4719 * doc/autoconf.texi: Add various further index entries.
4721 2003-12-29 Paul Eggert <eggert@twinsun.com>
4723 * bin/autoreconf.in (autoreconf_current_directory):
4724 Fix typo: mkdir without umask arg.
4726 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4728 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4729 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
4730 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
4731 explanation clearer.
4733 2003-12-24 Andreas Schwab <schwab@suse.de>
4735 * doc/autoconf.texi (Default Includes): Fix misspelling of
4736 AC_INCLUDES_DEFAULT.

4740 * configure.ac: Test if sh -n works.
4741 * configure: Regenerate.
4742 * tests/atlocal.in: Store the result here.
4743 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
4744 tools.at, looking in atlocal's ac_cv_sh_n_works instead
4745 of explicitly testing.
4746 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
4747 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
4748 * tests/tools.at (Syntax of the shell scripts): Simplify
4749 using AT_CHECK_SHELL_SYNTAX.

4763 Extracted from AS_SHELL_SANITIZE.
4764 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
4765 macros.
4766 (AS_SHELL_SANITIZE): Move reinvocation code from
4767 _AS_LINENO_WORKS, use it to find out if shell
4768 functions work.
4769 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
4770 does not work.
4771 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

4790 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

4833 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
4834 than $target since the latter is not usual, add guidelines on when to
4835 use or not use the system type.

4989 * doc/autoconf.texi (Function Portability): Add @prindex for exit.
4990 Add putenv and unsetenv. Add sysconf _SC_PAGE_SIZE.
4992 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
4994 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
4995 cross test.
4997 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
4999 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5000 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
5002 2003-10-10 Andreas Schwab <schwab@suse.de>
5004 * bin/autoheader.in: Avoid empty first line in --version and
5005 --help output.
5006 * bin/ifnames.in: Likewise.
5008 2003-10-09 Paul Eggert <eggert@twinsun.com>
5010 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
5011 Issue a more-informative diagnostic.
5012 Problems reported by Eric Sunshine.
5014 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5016 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5017 -mGLOB_options_string stuff for Intel ifc, which can cause
5018 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
5019 pattern-matching instead of grep.
5021 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5023 * doc/autoconf.texi: Document new FC Fortran macros.
5025 2003-10-08 Gary V. Vaughan <gary@gnu.org>
5027 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
5028 that future autopoint/aclocal/automake/autoreconf will be able
5029 to trace to find where to install local m4 macros.
5030 * doc/autoconf.texi (Input): Document it.
5031 * NEWS: Updated.
5033 2003-10-06 Gary V. Vaughan <gary@gnu.org>
5035 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
5036 -lcrtbegin.o to list of ignored flags and fix underquoting of
5037 -lcrt[01].o.
5039 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
5041 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5042 cache variable instead of $G77 to decide whether to include -O2,
5043 since $G77 is specific to Fortran 77.
5045 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5047 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
5048 free" flag. Re-order flags tested into rough order of popularity.
5050 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5052 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5053 arguments so that it can be used with syntax identical to
5054 AC_PROG_F77, and so that we can more easily decide to
5055 remove/deprecate the DIALECT optional argument in the future if it
5056 proves troublesome.
5057 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5058 non-freeform-supporting compilers. Document freeform flags.
5060 2003-10-03 Akim Demaille <akim@epita.fr>
5062 * configure.ac: Look for emacs, not macs.
5063 Reported by Eric Sunshine.
5065 2003-10-03 Akim Demaille <akim@epita.fr>
5067 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5068 * bin/autoreconf.in (autoreconf_current_directory): Create the
5069 AUX_DIR if needed, for sake of automake --add-missing etc.
5070 Suggested by Alexandre Duret-Lutz.
5072 2003-10-03 Akim Demaille <akim@epita.fr>
5074 * configure.ac: Quotation and formatting changes.
5075 (EMACS): Don't set it if it is not recent enough to support
5076 autoconf-mode.el.
5077 From Eric Sunshine.
5079 2003-10-02 Akim Demaille <akim@epita.fr>
5081 * bin/ifnames.in (&scan_file): Skip C++ comments.

5091 Version 2.57f.
5093 2003-09-30 Paul Eggert <eggert@twinsun.com>
5095 * lib/Autom4te/XFile.pm: Use Errno.
5096 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
5097 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
5099 2003-09-30 Akim Demaille <akim@epita.fr>
5101 * config/announce-gen (&print_news_deltas): Extracted from...
5102 (&print_changelog_deltas): here.
5103 (&news_file): Rename as...
5104 (@news_file): this.
5106 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
5108 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
5109 have been created when invoking the compiler.
5110 * tests/fortran.at (GNU Fortran 77): Quote $G77.
5112 2003-09-29 Akim Demaille <akim@epita.fr>
5114 Version 2.57e.
5116 * config/mkinstalldirs: Upgrade.
5118 2003-09-28 Paul Eggert <eggert@twinsun.com>
5120 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
5121 Problem reported by Lars J. Aas in
5122 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
5123 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5124 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5125 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5127 2003-09-26 Akim Demaille <akim@epita.fr>
5129 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5130 directory for AC_CONFIG_COMMANDS' first argument exists.
5131 This makes valid the invocation of _AC_SRCPATH that follows.
5132 Reported by Eric Sunshine.
5133 * doc/autoconf.texi (Configuration Commands): Adjust.
5135 2003-09-26 Akim Demaille <akim@epita.fr>
5137 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5138 Reported by Ralf Corsepius.
5140 2003-09-26 Akim Demaille <akim@epita.fr>
5142 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5143 arguments.
5144 Actually, use AU_ALIAS.
5145 From Bruno Haible.
5147 2003-09-26 Paul Eggert <eggert@twinsun.com>
5149 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
5150 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
5151 Problem reported by Eric Sunshine in:
5152 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
5154 2003-09-26 Akim Demaille <akim@epita.fr>
5156 The test suite are sometimes assigning timings incorrectly.
5157 Reported by Henk Krus.
5158 Diagnosed by Nicolas Joly.
5160 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5161 AT_help_all.
5162 Instead of making AT_help a sequence of assignments to grow
5163 $at_help_all, just make AT_help_all be the growing contents of
5164 $at_help_all, and make a single assignment in...
5165 (AT_INIT): here.
5166 (at_times_skip): Flip the meaning and rename as...
5167 (at_times_p): this.
5168 (AT_INIT): When summarizing the test that ran, remove
5169 $at_times_file after use, and check it is present before trying to
5170 use it.
5172 2003-09-25 Akim Demaille <akim@epita.fr>
5174 Version 2.57d.
5176 * bin/Makefile.am (edit): Handle '@configure_input@'.
5177 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5178 (ifnames): chmod -w.
5179 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5180 executables, not bin/ executables! Otherwise all the magic needed
5181 to find non installed files is turned off. This caused a failure
5182 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5183 as found in its environment (sent by tests/autoreconf): pointing
5184 to bin/autom4te that could not find its files.
5185 * tests/mktests.sh: Force the replacement of generated files, for
5186 the sake of "mv" program that are interactive when overwriting a
5187 -w file.
5188 * config/install-sh: Upgrade from CVS Automake.
5190 2003-09-23 Paul Eggert <eggert@twinsun.com>
5192 * doc/autoconf.texi (Limitations of Builtins): Document test -h
5193 versus test -L issues.
5195 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
5196 Paul Eggert <eggert@twinsun.com>
5198 Trivial change to support GCC's configuration procedure.
5199 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5200 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5201 about inconsistency if the preprocessor is set to give errors for
5202 any warning.
5203 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5205 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
5207 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
5208 and XFile.pm from Automake.
5209 * lib/Autom4te/XFile.pm: Update from Automake.
5211 2003-09-12 Akim Demaille <akim@epita.fr>
5213 Version 2.57c.
5215 2003-09-12 Akim Demaille <akim@epita.fr>
5217 * config/config.guess, config/config.sub, config/missing,
5218 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
5219 from masters.
5221 2003-09-12 Akim Demaille <akim@epita.fr>
5223 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5224 not asm/types.h.
5226 2003-09-11 Akim Demaille <akim@epita.fr>
5228 * doc/autoconf.texi (Header Portability): linux/random.h.
5229 From Peter Hendrickson.
5231 2003-09-10 Akim Demaille <akim@epita.fr>
5233 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5234 willing to edit the output files.
5236 2003-09-10 Akim Demaille <akim@epita.fr>
5238 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5239 and AC_FC_FREEFORM.
5240 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5241 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
5243 2003-09-09 Akim Demaille <akim@epita.fr>
5245 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
5246 Reported by Gary Vaughan.

5252 trailing files.
5254 2003-09-07 Paul Eggert <eggert@twinsun.com>
5256 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
5257 Improve the accuracy of the wording about obsolescence.
5258 From a suggestion by Ian Lance Taylor in
5259 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5261 2003-09-05 Paul Eggert <eggert@twinsun.com>
5263 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5264 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5266 2003-09-04 Akim Demaille <akim@epita.fr>
5268 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5269 AC_FUNC_WAIT3.
5271 2003-09-04 Akim Demaille <akim@epita.fr>
5273 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5274 (freeze): When exiting, use $exit_code.
5275 * lib/autoconf/fortran.m4: Comment changes.
5277 2003-09-04 Akim Demaille <akim@epita.fr>
5279 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5281 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5283 Add support for newer Fortran dialects. The F77 interface is
5284 unchanged, and continues to support Fortran 77. New FC macros
5285 correspond to all the old F77 macros, with output variables FC,
5286 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5287 available dialect, but older dialects can be specified. There are
5288 new macros AC_FC_SRCEXT to set the source extension, and
5289 AC_FC_FREEFORM to accept free-form source files.
5291 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5292 New macros.
5293 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
5294 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
5295 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
5296 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

5303 AC_FC_DUMMY_MAIN, _AC_FC_MAIN, AC_FC_MAIN, __AC_FC_NAME_MANGLING,
5304 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
5305 AC_FC_SRCEXT, AC_FC_FREEFORM):
5306 New macros.
5307 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
5308 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
5309 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5310 Rewrite in terms of the above.
5311 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5312 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
5313 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
5314 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
5316 2003-09-02 Paul Eggert <eggert@twinsun.com>
5318 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5319 Document problems with timestamp resolution that 'make', 'cp -p', and
5320 'touch -r' have.
5322 2003-08-27 Akim Demaille <akim@epita.fr>
5324 * tests/m4sugar.at (cross_warning): Make sure to enable the
5325 output, so that we can track spurious m4sugar output.
5326 * tests/local.at: Require 2.57.
5327 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5328 are defaulted by AT_CHECK anyway.
5329 Use AT_CHECK_AUTOM4TE.
5330 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5331 missing dnl.
5333 2003-08-27 Akim Demaille <akim@epita.fr>
5335 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5336 when -Wobsolete is set.
5337 Set it on by default.
5338 Suggested by Klee Dienes.
5340 2003-08-27 Akim Demaille <akim@epita.fr>
5342 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
5343 documentation.
5344 From Guido Draheim.
5346 2003-08-26 Akim Demaille <akim@epita.fr>
5348 * doc/autoconf.texi (Output): Make clear that one can run code
5349 after AC_OUTPUT.
5351 2003-08-25 Akim Demaille <akim@epita.fr>
5353 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
5354 CVS Bison.
5356 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
5358 * bin/autoreconf.in (parse_args): Do not pass --no-force to

5379 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
5380 * configure.ac: Require Automake 1.7.6.
5382 2003-08-22 Akim Demaille <akim@epita.fr>
5384 Output stack traces in warnings.
5386 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
5387 Replace the former...
5388 (m4_warn): Pass the call stack to _m4_warn.
5389 * bin/autom4te.in: Adjust to output the call stack.
5390 * tests/m4sugar.at (m4@&t@_warn): Adjust.
5392 2003-08-22 Akim Demaille <akim@epita.fr>
5394 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
5395 * bin/autom4te.in: Adjust.
5397 2003-08-21 Akim Demaille <akim@epita.fr>
5399 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
5400 (&verbose): Remove.
5401 (&getopt): Adjust the note and verb channels, depending upon
5402 --verbose.
5403 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
5404 * bin/autoupdate.in: Adjust.
5405 Use &verb, not &verbose.
5407 2003-08-21 Akim Demaille <akim@epita.fr>
5409 * bin/autoheader.in (&parse_args): Use &parse_warnings and
5410 &parse_WARNINGS.
5411 ($help): Use Autom4te::ChannelDefs::usage.
5412 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5413 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5415 2003-08-21 Akim Demaille <akim@epita.fr>
5417 First stab at preserving warnings between calls to autom4te,
5418 including when the cache is used.
5420 There are still several issues: (i) there are too many runs of m4
5421 (one for include, one for warnings, and some more), (ii) warnings
5422 spreading on several lines are not handled gracefully, (iii) the
5423 code meant to have the call stack display for errors does not work
5424 (its handling should move from m4 to autom4te).
5426 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5427 Use them.
5428 (@preselect): Add m4_warn.
5429 ($exit_status): Remove, use $exit_code.
5430 ($help): Use Autom4te::ChannelDefs::usage.
5431 (&handle_m4): No longer define the m4_warnings.
5432 At each run, extract and report the warnings.
5433 Always cache the result, including if the exit status is on
5434 failure, since if nothing changes, we should result in the same
5435 failure, hence we can use the cache.
5436 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5437 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5438 Remove.
5439 (m4_warn): Redefine as a do-nothing: it is its invocation that
5440 matters, as warnings are now reported via traces.
5441 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5442 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5443 the latter reveals calls to the former.
5445 Adjust the tests.
5447 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5449 2003-08-21 Akim Demaille <akim@epita.fr>
5451 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5452 Use them.
5454 2003-08-21 Akim Demaille <akim@epita.fr>
5456 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5457 forward order.
5458 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5459 (&parse_warnings): Accept a list of warning requests.
5460 (&usage): Return a string, not a side effect.
5461 (cross): New warning category.
5463 2003-08-21 Akim Demaille <akim@epita.fr>
5465 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)

5484 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5485 (&xsystem, &contents): Remove, since they are exported by...
5486 * lib/Autom4te/FileUtils.pm: this.
5487 More perldoc.
5488 * lib/Autom4te/General.pm (&up_to_date_p): Move to...

5550 2003-08-13 Derek Price <derek@ximbiot.com>
5552 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
5553 output.
5555 2003-08-12 Derek Price <derek@ximbiot.com>
5557 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
5558 (AT_CHECK_NOESCAPE): Move core functionality to...

5561 2003-08-07 Derek Price <derek@ximbiot.com>
5563 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
5564 (AT_CHECK_NOESCAPE): ...to this new macro.
5566 2003-07-31 Paul Eggert <eggert@twinsun.com>
5568 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5569 in Bash 2.01. Problem reported by Brian Gough in
5570 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
5572 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
5574 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
5575 -lcrt1.o, for OS X. (trivial change)
5577 2003-07-07 Paul Eggert <eggert@twinsun.com>
5579 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
5580 inside '#ifndef __cplusplus'. Problem reported by
5581 Bob Friesenhahn.
5583 2003-07-06 Bill Clarke <llib@computer.org>
5585 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5586 'long', not 'int', for benefit of Sun's recent C++ compilers
5587 (trivial change). See:
5588 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5589 (This really should be 'intptr_t', not 'long', but that would
5590 take more work.)
5592 2003-06-25 Akim Demaille <akim@epita.fr>
5594 * lib/Makefile.am (autom4te.cfg): Make it read only.
5595 Depend on Makefile since it contains substitutions.
5596 From Paolo Bonzini.

5601 2003-06-25 Akim Demaille <akim@epita.fr>

5604 From Gareth McCaughan.
5606 2003-06-23 Akim Demaille <akim@epita.fr>
5608 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5609 not all of them. This fixes 1. the fact that when testing
5610 Autoconf there are many many config.log, 2. the incorrect use of
5611 top_srcdir to find config.log.
5612 Don't mix the detailed output of failed test with the summary of
5613 failures. Rather, append detailed log afterwards.
5615 2003-06-23 Akim Demaille <akim@epita.fr>
5617 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5618 always run: output config.log on $at_group_log.
5620 2003-06-23 Akim Demaille <akim@epita.fr>
5622 * tests/torture.at (#define header templates): Don't use quotes in

5625 2003-06-23 Akim Demaille <akim@epita.fr>
5627 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5628 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5629 * tests/atspecific.m4: Rename as...

5632 * tests/local.at: here.
5633 * tests/Makefile.am: Adjust.

5636 2003-06-21 Kevin Ryde <user42@zip.com.au>
5638 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5639 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5640 ensuring we add -std1 for full-ANSI.
5642 * doc/autoconf.texi (hdrindex): New macro.

5645 2003-06-20 Akim Demaille <akim@epita.fr>

5649 2003-06-20 Akim Demaille <akim@epita.fr>
5651 Version 2.57a.
5653 2003-06-20 Akim Demaille <akim@epita.fr>
5655 * bin/autom4te.in: Don't rely on $HOME being defined.
5656 Reported by Marc Espie as PR/233.
5658 2003-06-20 Akim Demaille <akim@epita.fr>
5660 * lib/autotest/general.m4: Use at_times_file only if used.
5661 From Nicolas Joly.

5665 * config/config.guess, config/config.sub, config/elisp-comp,
5666 * config/install-sh, config/mkinstalldirs, doc/standards.texi:

5669 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
5671 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
5672 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5673 (TEST_SCRIPT): New diversion.
5674 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5675 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5676 (AT_INIT): Support for expected failures.
5678 2003-06-02 Akim Demaille <akim@epita.fr>
5680 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
5681 changes.
5682 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5683 Autoconf nor Automake.
5684 (&contents): New, from Automake.
5685 PODify.
5687 2003-05-28 Paul Eggert <eggert@twinsun.com>
5689 * NEWS, doc/autoconf.texi (Particular Functions),
5690 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5691 is the inverse of localtime.
5693 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5695 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5696 (handle_exec_errors): New function. Work around $! being
5697 altered by WEXITSTATUS.
5698 (xqx, xsystem): Use handle_exec_errors.
5700 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5702 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5703 Do not call `_exit()', simply modify `$?'.
5704 (xsystem): Reset $! before running system, and check it afterward.
5705 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5706 63 for version mismatches.
5708 2003-05-23 Akim Demaille <akim@epita.fr>
5710 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5711 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5712 the middle of a line).
5713 * lib/m4sugar/m4sugar.m4: Likewise.
5714 Remove useless spaces in comments.
5716 2003-05-23 Akim Demaille <akim@epita.fr>
5718 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5719 exit 63, so that we (or Automake's "missing") can tell the
5720 difference with a plain failure.
5721 * doc/autoconf.texi (Notices): Adjust.
5723 2003-05-23 Akim Demaille <akim@epita.fr>
5725 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5726 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5727 White spaces cleanup.
5729 2003-05-22 Jim Meyering <jim@meyering.net>
5730 Paul Eggert <eggert@twinsun.com>
5732 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5733 Remove `#include <stdlib.h>' from the list; we should never
5734 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5735 resulting namespace pollution would cause other tests to fail.
5736 Configure scripts run with some older versions of g++ and HP's
5737 aCC would fail due to such an #include. Problems reported by
5738 Matthew Mueller in <http://bugs.debian.org/120704> and by
5739 Keith Bostic in
5740 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5741 In the test, use the test declaration before including <stdlib.h>,
5742 as that's closer to how it'll be used.
5744 2003-05-23 Akim Demaille <akim@epita.fr>
5746 * doc/autoconf.texi (Header Portability): ucred.h.
5747 From Ian Redfern.
5749 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5751 Overhaul Autotest's logging: generate separate log files
5752 in testsuite.dir/NNN/testsuite.log, and append them to
5753 testsuite.log instead of re-running the test verbosely.
5755 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5756 file descriptor, write 0 to at_status_file instead of setting
5757 at_status=0, initialize some new variables (at_status_file,
5758 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5759 to rerun the tests, instead append the at_group_log to the
5760 at_suite_log when a test fails.
5761 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5762 with the AS_MESSAGE_LOG_FD redirected to stdout.
5763 (AT_CLEANUP): save the output status in $at_status_file
5764 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5765 its original place.
5766 (AT_CHECK): since tests are run with a redirected stdout,
5767 and used to be re-run in verbose mode, turn some $at_verbose
5768 into echo, and don't redirect the output of testing stdout
5769 and stderr.
5771 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5772 the name of the debugging directory and information about
5773 its contents.
5775 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5777 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
5778 parameter.
5780 2003-05-22 Akim Demaille <akim@epita.fr>
5782 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

5801 Suggested by Jim Meyering.
5803 2003-05-22 Akim Demaille <akim@epita.fr>
5805 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
5806 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
5807 Reported by Jim Meyering.
5809 2003-05-22 Akim Demaille <akim@epita.fr>
5811 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

5844 2003-05-17 Akim Demaille <akim@epita.fr>
5846 * lib/autoconf/functions.m4: Use the default includes so that
5847 memcmp be declared before being tested.
5848 Reported by Sander Niemeijer.
5849 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

5851 AC_INCLUDES_DEFAULT.
5853 2003-05-17 Akim Demaille <akim@epita.fr>
5855 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
5856 * doc/autoconf.texi (Obsolete Macros): Adjust.
5857 Reported by Werner LEMBERG and Debian Bug 190886.
5859 2003-05-16 Akim Demaille <akim@epita.fr>
5861 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
5862 user name space clashes.
5863 Reported by Bruno Haible.
5865 2003-05-16 Akim Demaille <akim@epita.fr>
5867 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
5868 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
5869 them uniform, and more robust to Perl special characters.
5870 Reported by Martin Mokrejs.
5872 2003-05-14 Akim Demaille <akim@epita.fr>
5874 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
5876 2003-05-14 Akim Demaille <akim@epita.fr>
5878 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

5883 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
5884 message.
5885 From Matthias Andree.
5887 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
5889 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
5890 and truncate.
5892 2003-05-06 Akim Demaille <akim@epita.fr>
5894 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5895 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5896 by aclocal.m4 is changed it might require the importing of another
5897 m4 extension file, i.e., aclocal must be run.
5899 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5900 (&parse_args): Use --force with aclocal if required and supported.
5901 (&autoreconf_current_directory): Use &run_aclocal.
5903 2003-05-06 Akim Demaille <akim@epita.fr>
5905 Lock autom4te's cache.
5907 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
5908 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
5909 argument instead of a file name, so that the request file remains
5910 open during the whole autom4te run.
5911 ($icache_file): New.
5912 (&freeze): Lock the $icache_file.
5914 2003-04-29 Derek Price <derek@ximbiot.com>
5916 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
5917 seperator with m4_append_uniq(). It doesn't work.
5918 (AT_CLEANUP): Add `;' to end of at_help_all.
5919 (AT_INIT): Allow --keywords to be specified more than once. When
5920 grepping $at_help_all for keywords, use the field and keyword
5921 seperators to ensure a complete keyword match. Alter at_prev handling
5922 to support the new --keywords behavior.
5924 2003-04-27 Karl Berry <karl@freefriends.org>
5926 * doc/autoconf.texi: Make the dir entries in the autoconf manual
5927 align better with others. I also made some of the individual
5928 entries on one line, for brevity and to make it easier for me to
5929 sort my dir-example file in the Texinfo distribution :).
5931 2003-04-12 Jim Meyering <jim@meyering.net>
5933 * NEWS: Mention the new macro.

6024 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
6025 obsolete AC_HELP_STRING.
6026 (AC_HELP_STRING): AU_DEFUN to...
6027 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
6028 * tests/m4sh.at (AS_HELP_STRING): New test.
6030 * tests/acgeneral.at: Regenerated.
6032 2003-03-26 Derek Price <derek@ximbiot.com>
6034 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
6035 sense. Verbosify the diversion definitions comment.

6075 (Automake): Automake 1.5+ no longer requires special tools to be
6076 present on the developer's host.
6078 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
6080 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

6084 * bin/autom4te.in (BEGIN): Likewise.
6085 * bin/autoreconf.in (BEGIN): Likewise.
6086 * bin/autoscan.in (BEGIN): Likewise.
6087 * bin/autoupdate.in (BEGIN): Likewise.

6092 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
6093 to cope with DOS-style absolute paths, when constructing
6094 ${ac_make}.
6096 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6097 When constructing paths with IFS=:, quote the path. If we're
6098 constructing a DOS-style absolute path, we don't want to split it
6099 on the colon.
6101 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
6102 in description.
6104 2003-02-25 Pavel Roskin <proski@gnu.org>

6112 2002-09-01 patch by replacing "test -n" with "test -z".
6113 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
6114 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
6116 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
6117 to fix a mismatch between example and discussion.
6119 2003-02-24 Kevin Ryde <user42@zip.com.au>
6121 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6122 format starting with "-".
6124 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6126 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6127 is not portable inside Makefile.
6129 2003-02-20 Akim Demaille <akim@epita.fr>
6131 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6132 compiler says yeah, but preproc says nope, compiler is right.
6133 Conversely, prompt the reader to send a bug report to the
6134 maintainers of the package, not of Autoconf.
6136 2003-02-20 Klee Dienes <kdienes@apple.com>
6138 * bin/autoreconf.in (autoreconf_current_directory): Properly
6139 handle an empty aclocal.m4.

6144 $ac_prefix_program.
6145 From Larry Jones.
6147 2002-12-23 Paul Eggert <eggert@twinsun.com>
6149 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6150 innocuous variant befor including <limits.h> or <assert.h>. This
6151 works around a bug reported by Albert Chin: HP-UX 11i
6152 (and earlier versions) have a <limits.h> that declares
6153 gettimeofday and many other functions.
6155 2002-12-03 Paul Eggert <eggert@twinsun.com>
6157 Version 2.57.
6159 * NEWS, configure.ac: Update version.
6161 * doc/fdl.texi: Upgrade to FDL version 1.2.
6163 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6164 nontrivially in main's body, so that f's external declaration is
6165 not optimized away in AIX. This should fix the bug reported by
6166 Martin Frydl in
6167 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6169 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6170 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6171 defined, to support freestanding compilers. This should fix the
6172 bug reported by Momchil Velkov in
6173 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6175 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6176 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

6181 * Makefile.maint (www-gnu): New macro.
6182 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6183 the location has moved.
6185 2002-12-02 Martin Frydl <martin@systinet.com>
6187 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6188 \(.*\) match is too long and there is something more to be checked.
6189 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
6191 2002-11-15 Akim Demaille <akim@epita.fr>

6197 * config/move-if-change: Indenting changes.
6198 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
6199 * configure.ac (AM_INIT_AUTOMAKE): here.
6200 Require 1.7.1.
6202 2002-11-14 Akim Demaille <akim@epita.fr>
6204 Version 2.55.
6206 * config/config.guess, config/config.sub, config/install-sh:
6207 Update from masters.
6209 2002-11-14 Akim Demaille <akim@epita.fr>
6211 * Makefile.maint: Sync with Bison, i.e.:
6212 (po-check): Scan .l and .y files instead of the
6213 .c and the .h files that they generate. This fixes the bug
6214 reported by Tim Van Holder in:
6215 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6216 Look for N_ as well as for _. Try to avoid matching #define for
6217 N_ and _.
6218 From Paul Eggert.
6220 2002-11-14 Akim Demaille <akim@epita.fr>
6222 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6223 From Paul Eggert and Albert Chin-A-Young.
6225 2002-11-14 Akim Demaille <akim@epita.fr>
6227 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6228 From Paul Eggert and Albert Chin-A-Young.
6230 2002-11-14 Kevin Ryde <user42@zip.com.au>
6232 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6233 than assigning in main, to avoid HP cc +O3 optimizing it away.
6235 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6237 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6238 option. Process --recheck after parsing all options. Pass -q
6239 option to configure on --recheck.
6240 (AC_OUTPUT): Pass -q from configure to config.status.
6241 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6242 arguments to record.
6243 * doc/autoconf.texi (config.status Invocation): Document
6244 config.status -q option.
6246 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
6248 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
6249 Makefile.in if Makefile.am exists.

6251 output AC_CONFIG_FILES if no Makefiles were found.
6253 2002-11-07 Akim Demaille <akim@epita.fr>

6260 2002-11-06 Akim Demaille <akim@epita.fr>
6262 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
6263 declaration in extern "C" too.

6266 2002-11-06 Akim Demaille <akim@epita.fr>
6268 * tests/torture.at (Configuring subdirectories): Don't use grep
6269 -w.
6270 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
6271 Reported by Ezra Peisach.
6273 2002-11-05 Akim Demaille <akim@epita.fr>
6275 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6276 Remove.
6277 We _have_ to stop using the old compatibility scheme that tried to
6278 avoid useless backslashes because Libtool 1.4.3 contains a
6279 AC_DEFINE([error_t], [int],
6280 [Define to a type to use for \`error_t' if it is not
6281 otherwise available.])
6282 We _have_ to quote the single quote and backslashes with \. The
6283 old compatibility scheme saw that ` was backslashed, and therefore
6284 did not quote the single quote. Hence before this patch, Autoconf
6285 was not compatible with Libtool.
6287 2002-11-04 Paul Eggert <eggert@twinsun.com>
6289 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6294 2002-11-04 Akim Demaille <akim@epita.fr>
6296 Version 2.54c.
6298 * Makefile.maint (update, cvs-update, po-update, do-po-update):
6299 New.
6300 * config/texinfo.tex: Update.
6302 2002-11-03 Akim Demaille <akim@epita.fr>
6304 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
6305 from...
6306 (&autoreconf): here.
6307 ($help, $make, &parse_args, &autoreconf_current_directory):
6308 Support -m/--make.
6309 * doc/autoconf.texi (autoreconf Invocation): Adjust.
6311 2002-10-31 Bruno Haible <bruno@clisp.org>

6324 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
6325 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
6327 2002-10-31 Akim Demaille <akim@epita.fr>
6329 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6330 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6331 Make variable, not a shell variable.
6332 Suggested by Bruno Haible.
6334 2002-10-31 Akim Demaille <akim@epita.fr>
6336 * bin/autom4te.in (load_configuration): Reject #args out of any
6337 language.
6339 2002-10-31 Akim Demaille <akim@epita.fr>
6341 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
6342 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
6343 (_AC_RUN_IFELSE): Use it.
6344 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
6345 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
6346 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
6347 inline it.

6353 Suggested by Tim van Holder.
6355 2002-10-29 Paul Eggert <eggert@twinsun.com>
6357 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
6358 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
6359 Problem reported by Bruno Haible.
6361 2002-10-29 Akim Demaille <akim@epita.fr>
6363 * doc/autoconf.texi (Header Templates): Put also in words what the
6364 pictures says to assist free style readers.
6365 (Customizing autom4te): s/--cache=/--cache /.
6367 2002-10-29 Akim Demaille <akim@epita.fr>
6369 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
6370 sys/wait.h.
6371 sparc_address_test returns void.
6372 Use it with an argument, as prototyped.
6373 From Bruno Haible.
6375 2002-10-29 Akim Demaille <akim@epita.fr>
6377 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

6383 * tests/torture.at (Deep Package): New test.

6389 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
6390 * doc/autoconf.texi (Invoking autom4te): Rename as...
6391 (autom4te Invocation): this, for consistency with the other nodes.

6404 2002-10-28 Akim Demaille <akim@epita.fr>
6406 * configure.ac: Bump to 2.54c.

6617 2002-10-22 Akim Demaille <akim@epita.fr>

6623 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""

6676 Reported by Alexandre Duret-Lutz.
6678 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
6679 to frozen files in @ARGV, as @ARGV must remain being a list of

6682 (&freeze): Use &error.
6683 (&up_to_date): If a file that was included according to the cache
6684 is no longer there, then the output is out dated.

6686 --force is given.
6687 * tests/tools.at (autom4te cache): New.

6696 that error messages can be easily located, and use GNU Make
6697 format, so that Emacs' compile mode understands us.
6698 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6699 if some file was changed instead of `print'.
6700 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

6734 file name to enable parallel executions.
6735 From Sam Varshavchik.
6737 2002-10-08 Akim Demaille <akim@epita.fr>
6739 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6740 aclocal invocation, as Gettext macros might not be visible to
6741 aclocal.
6742 Instead of blindly running autopoint, scan configure.ac (not the
6743 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6744 Reported by Paul D. Smith.
6746 2002-10-08 Paul Eggert <eggert@twinsun.com>
6748 Work around problems found when POSIXLY_CORRECT=1 is set.
6749 None of this seems to have anything to do with POSIX, really,

6751 * bin/autom4te.in (parse_args): Configure GetOpt with
6752 "permute", too.
6753 * doc/autoconf.texi (Invoking autom4te):

6776 * tests/torture.at (Configuring subdirectories): Be robust to
6777 users who use config.site to require for a cache: in this case,
6778 the two last configure runs, using two different sets of
6779 arguments, trigger a legitimate error.
6781 2002-09-28 Akim Demaille <akim@epita.fr>

6817 * lib/autoscan/Makefile.am: Include freeze.mk.
6818 (autoscan.list): New target --this file is no longer a source.
6819 (autoscan.pre): New file.

6826 tracking changes in autoscan.list.
6827 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6829 2002-09-28 Akim Demaille <akim@epita.fr>

6845 2002-09-28 Akim Demaille <akim@epita.fr>

6850 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6851 all.
6852 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6853 explicit.
6855 2002-09-28 Akim Demaille <akim@epita.fr>
6857 * bin/autoscan.in (%c_keywords): Remove.

6943 Suggested by Guido Draheim.
6945 2002-09-13 Akim Demaille <akim@epita.fr>
6947 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6948 (chdir_init) might hang when stat'ing mounted directories.
6949 Reported by Vance Shipley.
6951 2002-09-12 Akim Demaille <akim@epita.fr>
6953 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6954 the lists.
6956 2002-09-12 Akim Demaille <akim@epita.fr>
6958 * doc/autoconf.texi (Defining Symbols): Present two different
6959 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
6960 difference between 1 argument calls, and 2-3 argument calls.
6962 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
6964 * doc/autoconf.texi: Review grammar and punctuation.
6966 2002-09-11 Paul Eggert <eggert@twinsun.com>
6968 * doc/autoconf.texi: Fix minor formatting, spelling, and
6969 grammatical typos.
6970 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6971 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6972 is obsolescent.
6974 2002-09-11 Akim Demaille <akim@epita.fr>
6976 * doc/autoconf.texi (Questions): Rename as...
6977 (FAQ): this.
6978 (Defining Directories): New.
6980 2002-09-09 Akim Demaille <akim@epita.fr>
6982 * doc/autoconf.texi (Making testsuite Scripts): Update.
6983 Suggested by Nishio Futoshi.
6985 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
6987 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
6988 plain `@' is wanted.
6990 2002-09-09 Akim Demaille <akim@epita.fr>
6992 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6993 `duplicates', since the algorithm was too naive and could keep
6994 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
6995 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6996 Reported by Ralf Corsepius.
6997 * tests/torture.at (Configuring subdirectories): Exercise these
6998 cases.
7000 2002-09-09 Akim Demaille <akim@epita.fr>
7002 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7003 looking for a replacement file.
7004 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7005 directory is relative.
7006 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7007 directory definition.
7008 Reported by Andreas Schwab and Jim Meyering.
7010 2002-09-06 Akim Demaille <akim@epita.fr>
7012 * doc/autoconf.texi (Setting Output Variables): Clarify what
7013 precious variables are.
7014 Suggested by Pontus Skoeld.
7016 2002-09-05 Akim Demaille <akim@epita.fr>
7018 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7019 (ifnames, autoscan, autom4te): Since we don't only depend on
7020 configure.ac variables (such as VERSION etc.), but also on prefix
7021 and so forth, depend on Makefile, not configure.ac.
7022 Reported by Alexandre Duret-Lutz.
7023 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7025 2002-09-05 Kevin Ryde <user42@zip.com.au>
7027 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7028 doesn't seem to be confined to ia64, just say "some versions".
7030 2002-09-04 Akim Demaille <akim@epita.fr>
7032 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7033 Automake 1.6c.
7034 * Makefile.am (maintainer-clean-local): Remove.
7035 (MAINTAINERCLEANFILES): Remove COPYING.
7037 2002-09-03 Paul Eggert <eggert@twinsun.com>
7039 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7040 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7041 Brinkmann.
7043 2002-09-03 Akim Demaille <akim@epita.fr>
7045 * configure.ac: Bump to 2.53d.
7046 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7047 as of today, on Automake's team suggestion.
7049 2002-09-03 Akim Demaille <akim@epita.fr>
7051 Version 2.53c.
7053 2002-09-02 Akim Demaille <akim@epita.fr>
7055 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7056 SITE_MACRO_DIR.
7057 * configure.ac: Disable SITE_MACRO_DIR.
7059 2002-09-02 Jim Meyering <meyering@lucent.com>
7061 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7062 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7063 Also, tweak grammar: s/make sure to/be sure to/.
7065 2002-09-02 Paul Eggert <eggert@twinsun.com>
7067 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7068 directory names are generally preferable to physical names.
7070 2002-09-02 Akim Demaille <akim@epita.fr>
7072 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7073 Reported by Raja R. Harinath.
7074 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7075 * bin/autoupdate.in: Use error instead of die.
7077 2002-09-01 Paul Eggert <eggert@twinsun.com>
7079 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7080 ordinary shell concatenation rather than echo+tr+sed command that
7081 runs afoul of a long-line-related sed bug in Solaris 8.
7083 * bin/autoheader.in (parse_args): --warning -> --warnings.
7085 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7086 stdout, as traditional "ls" does.
7087 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7088 _AC_COMPILER_EXEEXT_O): Likewise.
7089 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7091 * bin/autoconf.as: Add --prepend-include option. This patch was
7092 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7093 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7095 * bin/autoconf.in, configure: Regenerate.
7097 * doc/autoconf.texi (Special Shell Variables): Mention
7098 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7100 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7101 MAILPATH and set PS1, PS2, PS4 to default values, to work
7102 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7103 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7104 the Autoconf documentation specifies; fall back to "unset" only if
7105 this fails. Use a shell for-loop for this rather than an m4 loop,
7106 to shorten the output script.
7108 2002-08-30 Paul Eggert <eggert@twinsun.com>
7110 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7111 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7112 for the CDPATH problem. Document PWD.
7113 (Limitations of Builtins): Document the problem that "cd $foo" and
7114 "ls $foo" may refer to different directories in shells conforming
7115 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7116 example, since the old example is now out of date.
7118 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7119 FOO" and "ls FOO" talk about different directories; this catches
7120 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7121 spaghetti.
7123 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7124 of rolling our own unset.
7125 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7126 in practice we needn't worry about CDPATH if unset doesn't work.
7128 * Makefile.in, aclocal.m4, bin/Makefile.in,
7129 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7130 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7131 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7132 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7133 tests/Makefile.in: Regenerate with Automake 1.6.3.
7135 * config/config.guess, config/config.sub, config/mkinstalldirs:
7136 Update.
7138 * configure: Regenerate with self.
7140 2002-08-30 Kevin Ryde <user42@zip.com.au>
7142 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7143 default output.
7145 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7147 * bin/autom4te.in (Request::load): Correctly test for "do" read
7148 failure.
7150 2002-08-29 Akim Demaille <akim@epita.fr>
7152 * lib/Autom4te/General.pm (&xqx): New.
7153 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7154 hand, which is not portable.
7155 (&error): New.
7156 * bin/autom4te.in: Use them.
7157 Use &error instead of die.
7158 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7159 Adjust.
7161 2002-08-17 Paul Eggert <eggert@twinsun.com>
7163 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7164 default list of compilers to try, since it was long ago superseded
7165 by the ksh fc builtin. Suggested by Steven G. Johnson.
7167 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7169 * doc/autoconf.texi (Invoking autom4te): End the option table,
7170 fixing a bug introduced by the previous patch.
7171 (Limitations of Make): Add a 'target lookup' subentry in the
7172 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7174 2002-07-29 Mark D. Roth <roth@feep.net>
7176 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7177 options and use $AUTOM4TE_PATH.
7178 * doc/autoconf.texi: Remove documentation of autom4te
7179 --include-envvar and --site-macro-subdir options and document
7180 use of $AUTOM4TE_PATH.
7181 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7182 arguments from each language section.
7184 2002-07-29 Paul Eggert <eggert@twinsun.com>
7186 * doc/install.texi: Include copyright symbol in copyright notice.
7188 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7189 Replace with:
7190 (AM_MAKEINFOFLAGS): New macro.
7191 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7192 * Makefile.am (INSTALL): Use the new macros.
7193 Use -o rather than --output, since "missing" does not grok --output.
7195 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7197 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7198 comments do not always work. Never trust the exit status of
7199 `make -k'.
7201 2002-07-24 Kevin Ryde <user42@zip.com.au>
7203 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7204 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7206 2002-07-23 Paul Eggert <eggert@twinsun.com>
7208 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7209 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7210 apparently treats PATH="nonexistent" as if it contained ".".
7211 Bug reported by Stefan `Sec' Zehl.
7213 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7215 * doc/autoconf.texi (Limitations of Make): Mention the special
7216 handling of the obj/ directory by BSD make.

7221 backslashes.
7223 2002-07-19 Akim Demaille <akim@epita.fr>

7232 2002-07-18 Akim Demaille <akim@epita.fr>
7234 Version 2.53b.
7236 2002-07-18 Akim Demaille <akim@epita.fr>
7238 * config/config.guess, config/config.sub: Update.
7240 2002-07-18 Akim Demaille <akim@epita.fr>

7250 Alexandre Duret-Lutz <duret_g@epita.fr>
7252 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

7258 description of the tarname default.

7262 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
7263 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
7264 latter was not run.
7266 2002-07-17 Akim Demaille <akim@epita.fr>
7268 * lib/Autom4te/General.pm (find_file): Browse the directories in
7269 the order they are given.

7289 macro directory, remove note that include path directories are
7290 used in reverse order, and document --prepend-include option.
7291 * lib/autom4te.in: Use --prepend-include instead of --include.
7292 * tests/wrapsh.in: Use --prepend-include instead of --include.

7349 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7350 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7351 so that we consistently test the just-built programs.
7352 * tests/wrappl.as: Likewise.
7354 2002-06-12 Paul Eggert <eggert@twinsun.com>
7356 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

7360 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7361 * bin/autoscan.in (autom4te): Likewise.

7364 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7365 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7366 on Solaris 2.5.1.
7368 2002-06-11 Andreas Schwab <schwab@suse.de>
7370 * doc/autoconf.texi: Add more dir entries.
7372 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7374 * bin/autom4te.in ($cache): Don't define using `$me', the name
7375 of the cache should not depend on the name under which autom4te
7376 was installed.
7378 2002-06-07 Akim Demaille <akim@epita.fr>
7380 * tests/tools.at (autoconf: forbidden tokens, basic)
7381 (autoconf: forbidden tokens, exceptions): Adjust to the change of
7382 words in autom4te.in.
7384 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7386 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7387 _AC_LANG_PROGRAM_C_F77_HOOKS.
7389 2002-06-07 Akim Demaille <akim@epita.fr>

7432 2002-06-05 Paul Eggert <eggert@twinsun.com>
7434 * config/config.guess, config/config.sub, config/texinfo.tex:
7435 Update from masters.
7437 2002-05-29 Paul Eggert <eggert@twinsun.com>
7439 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
7440 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
7441 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):
7442 Likewise.

7452 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
7453 * doc/autoconf.texi (Particular Programs): Document them.
7454 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
7455 * NEWS: Likewise.
7457 2002-05-27 Paul Eggert <eggert@twinsun.com>
7459 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
7460 * NEWS, doc/autoconf.texi (Particular Types): Document it.
7461 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
7462 instead of AC_MBSTATE_T, which never existed.
7464 2002-05-23 Akim Demaille <akim@epita.fr>
7466 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7467 version of Autoconf that is discussed.
7469 2002-05-22 Paul Eggert <eggert@twinsun.com>
7471 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7472 from the default list of compilers to try. Suggested by
7473 Kate Hedstrom.
7474 * NEWS: Document the above.
7475 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7477 2002-05-17 Paul Eggert <eggert@twinsun.com>
7479 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7480 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7481 This improves on an earlier suggestion by H. Peter Anvin.
7483 2002-05-16 Paul Eggert <eggert@twinsun.com>
7485 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7486 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7487 Both macros now accept an optional source-dir arg.
7488 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7490 * NEWS: Document this.
7491 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7493 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7494 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7495 not for GNU extensions; this undoes part of the 2000-11-03 change,
7496 reverting to 2.13-compatible behavior.
7497 Add new optional argument DIR.
7498 (AC_FUNC_FNMATCH_GNU): New macro.
7500 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7502 2002-05-08 Paul Eggert <eggert@twinsun.com>
7504 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7505 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7506 and it causes a 'test' syntax error if it fails.
7507 Bug reported by Stephen Gildea.
7509 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7510 If prototypes are supported, use them to check this at compile-time,
7511 instead of trying to check it at run-time. If we must do a run-time
7512 check, assume that setvbuf is standard when cross-compiling, as
7513 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7514 Bug reported by Paul D. Smith.
7516 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7517 argument specifying location of getloadavg.c. This removes a
7518 FIXME. This idea was taken from Jim Meyering's implementation in
7519 textutils.
7520 * doc/autoconf.texi (Particular Functions): Document this.
7521 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7522 that's what the code does; this fixes a bug reported by
7523 Paul D. Smith.
7525 2002-05-03 Akim Demaille <akim@epita.fr>
7527 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7528 autopoint instead of gettextize.
7529 ($uses_alocal): Rename as...
7530 ($uses_aclocal): this.
7531 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7532 Suggested by Bruno Haible.
7534 2002-05-03 Akim Demaille <akim@epita.fr>
7536 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7538 2002-04-29 Paul Eggert <eggert@twinsun.com>
7540 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7541 files to be 1 second older; just set them to be the same time.
7542 Also, sleep 1 second after the first aclocal, to work around
7543 problems with sub-second time stamps on the input files.
7545 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7547 * doc/autoconf.texi: Mention "set -e -x" lossage
7548 under node "Limitations of Builtins".
7550 2002-04-29 Akim Demaille <akim@epita.fr>
7552 * doc/install.texi: Better wording for setting variables when
7553 running configure.
7554 From Christian Cornelssen.
7556 2002-04-29 Akim Demaille <akim@epita.fr>
7558 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7559 of lack of $LINENO support, then the test will compare the $LINENO
7560 in testsuite vs. the lineno in the test file. This is wrong, of
7561 course.
7562 Be sure to protect it.
7563 Reported by Patrick Welche.
7565 2002-04-25 Akim Demaille <akim@epita.fr>
7567 * doc/autoconf.texi (Obsolete Macros): Typo.
7568 Reported by Vladimir Volovich.
7570 2002-04-25 Akim Demaille <akim@epita.fr>
7572 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7573 than some of the input files, hence, on the second run of aclocal,
7574 if some of its input are younger, make them older.
7575 Suggested by Paul Eggert.
7577 2002-04-25 Akim Demaille <akim@epita.fr>
7579 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7580 Thanks to Paul Eggert.
7582 2002-04-25 Akim Demaille <akim@epita.fr>
7584 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7585 and ac_subst_vars be sh variables containing the list of
7586 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7587 DEFAULT diversion.
7588 (_AC_INIT_PREPARE): Use them to log them.
7589 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7590 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7591 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7592 _AC_SUBST_FILES and _AC_SUBST_VARS.
7593 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7595 2002-04-24 Akim Demaille <akim@epita.fr>
7597 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7598 autoheader, so that automake does not complain about a missing
7599 config.h.in that was to be created.
7601 2002-04-23 Akim Demaille <akim@epita.fr>
7603 * bin/autoheader.in (parse_args): --warning takes an argument.
7604 Fixes PR/220.
7606 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7608 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
7609 and bb.out when cleaning up.
7611 2002-04-22 Akim Demaille <akim@epita.fr>
7613 Version 2.53a.
7615 2002-04-22 Akim Demaille <akim@epita.fr>
7617 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
7619 2002-04-22 Akim Demaille <akim@epita.fr>
7621 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
7622 comma.
7623 Reported by Gregory Giannoni.
7625 2002-04-22 Akim Demaille <akim@epita.fr>
7627 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
7628 Fixes false failures on Darwin.
7630 2002-04-21 Paul Eggert <eggert@twinsun.com>

7634 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

7653 Minor spelling and grammar fixes.
7655 * doc/autoconf.texi: Follow the outline suggested in the GNU
7656 Sample Texts sections of the Texinfo 4.2 manual. Most
7657 importantly, this makes sure that the copyright notices appear in
7658 all output formats. You probably need Texinfo 4.2 to generate
7659 the manual now.
7661 Fix some bugs when using "$@" when there might be zero positional
7662 arguments in cases where this matters.

7682 * tests/c.at: We can't have zero arguments, so remove workaround
7683 that is not portable to Zsh.
7685 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7687 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
7688 from aclocal.m4 too.
7690 2002-04-12 Akim Demaille <akim@epita.fr>
7692 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
7694 2002-04-10 Akim Demaille <akim@epita.fr>
7696 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7697 workaround for ${1+"$@"}.
7698 * doc/autoconf.texi (Shell Substitutions): Explain it.
7699 From Oliver Kiddle and Peter Stephenson.
7701 Have M4sh perform minimal shell sanitizing.
7703 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7704 part into...
7705 (_AS_PREPARE): this new macro.
7706 (AS_PREPARE): New.
7707 (AS_INIT): Invoke AS_SHELL_SANITIZE.
7708 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7710 Adjust Autoconf and Autotest.
7712 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
7713 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7714 * lib/autotest/general.m4 (AT_INIT): Likewise.
7715 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7716 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7717 AS_SHELL_SANITIZE.
7719 Use this M4sh to generate Autoconf's shell scripts.
7721 * tests/wrapsh.as: New, precursor of wrapsh.in.
7722 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7723 on Autotest and M4sh.
7724 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7725 (wrapsh.in): New target.
7726 * bin/autoconf.as: New, precursor of autoconf.in.
7727 (autoconf.in): New target.
7729 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

7732 with indented comments in rules.
7734 2002-04-09 Andreas Schwab <schwab@suse.de>
7736 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
7737 ac_top_builddir when setting ac_abs_top_builddir.
7739 2002-04-06 Kevin Ryde <user42@zip.com.au>
7741 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
7742 (Portable Shell): Cross reference to Systemology.
7744 2002-04-05 Akim Demaille <akim@epita.fr>
7746 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
7747 directories when descending in a SUBDIRS.
7748 Reported by Ezra Peisach.
7750 2002-04-04 Andreas Schwab <schwab@suse.de>
7752 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7753 contains no literal separators.
7755 2002-04-03 Akim Demaille <akim@epita.fr>
7757 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
7758 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
7759 Use dnl, not the KILL diversion.
7760 Extracted from...
7761 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
7762 (AC_CONFIG_LINKS): here.
7763 Adjust.
7764 Don't use the KILL diversion, as it kills spurious output, which
7765 results in failures being hidden.
7766 Use m4_defn where appropriate.
7767 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7768 after the second argument.
7769 Use m4_defn.
7770 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7771 syntax, as it is provided by M4sugar.
7772 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
7774 2002-04-03 Andreas Schwab <schwab@suse.de>
7776 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
7777 expanded if $# <= 2.

7780 aclocal.
7782 2002-04-03 Akim Demaille <akim@epita.fr>

7787 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
7788 (_AC_COMPILER_OBJEXT): Use them.
7789 Fixes Debian #138666.
7791 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
7793 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

7796 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
7797 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
7798 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
7799 (AC_C_CONST): Same.

7808 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
7809 _AS_MKDIR_P_PREPARE.
7811 2002-03-28 Kevin Ryde <user42@zip.com.au>
7813 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
7814 to avoid versions of HP C which don't allow that.
7816 2002-03-27 Paul Eggert <eggert@twinsun.com>
7818 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7819 (AS_SHELL_SANITIZE): Invoke it.
7820 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

7830 2002-03-25 Paul Eggert <eggert@twinsun.com>
7832 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7833 as POSIX requires, as it doesn't work with Zsh.
7834 * doc/autoconf.texi (Assignments): Document the problem.
7836 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7838 * doc/autoconf.texi (Limitations of Make): Mention more issue
7839 about VPATH, overriding of macros in sub-makes, and handling of
7840 SHELL.
7842 2002-03-21 Paul Eggert <eggert@twinsun.com>
7844 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7845 problem with here-document buffer boundaries.
7847 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7848 when reinvoking the shell, to work around problems with installers
7849 who put strange things like "cd" commands in their environments.
7851 2002-03-19 Akim Demaille <akim@epita.fr>

7864 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
7865 From Nishio Futoshi.
7867 2002-03-19 Akim Demaille <akim@epita.fr>
7869 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
7871 2002-03-18 Paul Eggert <eggert@twinsun.com>
7873 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7874 (Limitations of Usual Tools): Add mkdir section.
7876 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7877 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7878 back on AS_DIRNAME to compute prefixes otherwise; this is
7879 roughly what mkinstalldirs does. That way, we need not have
7880 our own filename disassembler. The old disassembler did not
7881 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7883 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7884 Create at_test_all by a series of assignments,
7885 not by a single assignment of a long string. The latter causes ksh
7886 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7887 presumably because of a buffer overrun.
7889 2002-03-14 Paul Eggert <eggert@twinsun.com>
7891 * lib/autotest/general.m4 (at_times_skip):
7892 Renamed from at_times. Now a boolean.
7893 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7894 says 'times: not found'.
7896 2002-03-14 Akim Demaille <akim@epita.fr>
7898 * bin/autoreconf.in (&study_gettextize): New.
7899 (&autoreconf): Handle newest gettextize.

7912 2002-03-13 Akim Demaille <akim@epita.fr>
7914 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp

7921 m4_require.
7923 2002-03-11 Andreas Schwab <schwab@suse.de>
7925 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
7926 does not do it if --with-lispdir is given.
7928 2002-03-08 Akim Demaille <akim@epita.fr>
7930 Version 2.53.
7932 2002-03-08 Akim Demaille <akim@epita.fr>

7941 2002-03-08 Akim Demaille <akim@epita.fr>
7943 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7944 aliases the actual variables, and modifications of the former
7945 affect the latter.
7947 2002-03-08 Akim Demaille <akim@epita.fr>
7949 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7950 because of C-c: have m4 output in tmp files, then mv them.

7954 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

7980 parallel builds.
7982 2002-03-04 Akim Demaille <akim@epita.fr>
7984 * doc/autoconf.texi (Transforming Names): Equality between target
7985 and host is irrelevant.
7986 (Specifying Names, Canonicalizing): Remove all references to the
7987 backward compatibility hooks. Rather, collect them all into...
7988 (Hosts and Cross-Compilation): this new section.
7989 * doc/install.texi (System Type): Ditto.
7990 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7991 that `--host' implies cross-compilation.
7993 2002-03-04 Akim Demaille <akim@epita.fr>
7995 * doc/autoconf.texi (Evaluation Macros): New.
7996 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7997 useless.
7998 (_m4_foreach): Define the variant with immediate evaluation so
7999 that it contains exactly the items, not an expression which
8000 evaluation is the current item.
8001 (m4_re_string, m4_re_word): Don't over quote them.
8003 2002-03-04 Akim Demaille <akim@epita.fr>
8005 Instead of having stacking `shift's evaluated at the end, let
8006 `foreach' loops immediately evaluate them.
8008 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8009 $*. This is the n-th time I change my mind, but hopefully this is
8010 the last...
8011 (m4_lquote): New.
8012 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8013 efficient.
8014 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8015 it was only a hack for m4_text_wrap.
8016 (m4_car2): Remove, replaced by...
8017 (m4_cdr): New.
8018 (_m4_foreach): Adjust.
8019 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8020 m4_bpatsubst for clarification.
8022 2002-03-04 Akim Demaille <akim@epita.fr>

8050 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
8051 From Akinori Musha.

8055 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8056 translate \r\n to \n.

8069 2002-02-07 Akim Demaille <akim@epita.fr>
8071 Fix Autoconf PR/207:

8074 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

8086 case/esac, some shells don't support it.
8087 Reported by Zack Weinberg.

8090 2002-02-06 Akim Demaille <akim@epita.fr>
8092 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8093 sure not to introduce newlines in at_groups.

8096 2002-02-06 Akim Demaille <akim@epita.fr>
8098 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8099 is not available.

8106 not unsigned long.
8107 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8108 cross-compilers, too. This undoes some of the most recent change
8109 to this file.
8111 2002-02-05 Akim Demaille <akim@epita.fr>
8113 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8114 to make sure they are up to date when `check' is run.

8125 2002-02-05 Akim Demaille <akim@epita.fr>
8127 Implement `autom4te --freeze'.
8129 * bin/autom4te.in (&freeze): New.
8130 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8131 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8133 2002-02-05 Akim Demaille <akim@epita.fr>
8135 * bin/autom4te.in (&parse_args): Implement `frozen files are
8136 optional are the sum of the previous files on the command line'.
8137 Also, pass `--reload-state=' on them, so...
8138 (handle_m4): don't.
8139 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8140 (M4sh): Rely on M4sugar.
8141 (Autotest, M4sh, M4sugar): Use frozen files.
8143 2002-01-31 Akim Demaille <akim@epita.fr>
8145 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8146 * doc/autoconf.texi (Initializing configure): Adjust.
8148 2002-01-30 Akim Demaille <akim@epita.fr>
8150 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8151 alphanumeric to `-' instead of `_'.
8153 2002-01-30 Akim Demaille <akim@epita.fr>
8155 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8156 for plain code, the other for cross-compilation code. The latter
8157 is now run with GCC only.
8158 * doc/autoconf.texi (Compilers and Preprocessors): New.
8160 2002-01-30 Akim Demaille <akim@epita.fr>
8162 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8163 values.
8164 * doc/autoconf.texi (Initializing configure): Explain how to
8165 change AC_INIT default values.
8167 2002-01-29 Akim Demaille <akim@epita.fr>
8169 * tests/torture.at (Configuring subdirectories): Use configure.in,
8170 so that aclocal 1.4 works.
8171 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8173 2002-01-28 Akim Demaille <akim@epita.fr>
8175 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8176 needs an argument.
8178 2002-01-28 Akim Demaille <akim@epita.fr>
8180 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8181 AUTOTEST_PATH *after* it was set.
8182 Don't put `.' in the PATH: the user should be precise and `./' if
8183 needed. In addition, given that the test suite does some `cd', if
8184 `.' is in the path, the `tested programs' sections will report
8185 programs found in the test suite's directory, while during the
8186 tests (performed in their own directory), these programs are no
8187 longer visible. In other words, the results is confusing and
8188 useless.
8189 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8191 2002-01-24 Akim Demaille <akim@epita.fr>
8193 Version 2.52g.

8202 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8203 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8204 Bourne. Use /bin/sh.
8205 From Andreas Buening.
8207 2002-01-24 Akim Demaille <akim@epita.fr>
8209 * config/config.guess, config/config.sub, config/texinfo.tex:

8219 Automake.

8231 2002-01-21 Akim Demaille <akim@epita.fr>
8233 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8234 message on invalid options.
8235 * bin/autom4te.in (parse_args): Don't use
8236 Autoconf::General::getopt with non valid options.
8238 2002-01-17 Jim Meyering <meyering@lucent.com>
8240 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8241 $ac_cv_exeext so we don't use an old, invalid, cached value.
8243 2002-01-11 Akim Demaille <akim@epita.fr>
8245 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
8246 Meyering.

8248 limitation.

8254 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8255 package.m4, since is really depends upon configure.ac, not
8256 configure.
8257 * doc/autoconf.texi (testsuite Scripts): Adjust.
8258 * tests/Makefile.am (package.m4): New.
8259 EXTRA_DIST it since its a source.
8261 2002-01-06 Akim Demaille <akim@epita.fr>
8263 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8264 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8265 and PACKAGE_BUGREPORT from here...
8266 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8267 arguments.
8268 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8269 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8270 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8271 * tests/tools.at (autoheader): Adjust.
8272 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8274 2002-01-06 Akim Demaille <akim@epita.fr>

8293 2001-12-14 Akim Demaille <akim@epita.fr>
8295 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8296 trailing files, don't apply `-rf' to files which might not be
8297 created by configure (core, core.*, and *.core), but just `rm -f'.
8298 Suggested by Jonathan Kamens.
8300 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8302 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8304 2001-12-14 Akim Demaille <akim@epita.fr>
8306 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8308 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

8334 2001-11-26 Akim Demaille <akim@epita.fr>
8336 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8337 Remove $filepath, useless.
8338 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8339 variables, they are really part of the tokens.
8340 Split the input line on spaces and then look for tokens.
8341 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8342 because of `lex$U.$(OBJEXT)'.
8343 (&scan_files): Use "@list" instead of join.
8344 * doc/Makefile.am (CLEANFILES): Add *.fns.
8346 2001-11-26 Akim Demaille <akim@epita.fr>

8351 In particular autoscan and autoheader want -I.
8352 * configure.ac: Adjust.

8407 spotted by Jim Meyering.
8409 2001-11-16 Paul Eggert <eggert@twinsun.com>
8411 This patch implements a `long double' suggestion by Oliver Kiddle.
8413 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8414 static, to catch errors if the value isn't known at compile-time
8415 and the compiler supports dynamic arrays. Change its name from
8416 `_array_' to `test_array' to avoid potential name clashes.
8417 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8418 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8419 better than double. Catch a bug in GCC 2.95.2 x86.
8420 * doc/autoconf.texi (C Compiler): Document the above.
8421 * NEWS: Likewise.
8423 2001-11-13 Akim Demaille <akim@epita.fr>

8426 hand.
8427 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8429 2001-11-13 Akim Demaille <akim@epita.fr>
8431 * lib/autotest/general.m4 (AT_INIT): After having run the test
8432 group, go back to the initial directory, not to at_suite_dir.
8434 2001-11-13 Akim Demaille <akim@epita.fr>
8436 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8437 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8438 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8439 option.
8440 (AT_CHECK_CONFIGURE): Use absolute paths.
8441 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8442 The problem is still the old one: there is no means in M4 (that I
8443 know about) to create a defining macro, because there is no means
8444 to create `$1' etc., therefore, the defining macro ``swallows''
8445 all the arguments meant to the defined macro.
8447 2001-11-13 Akim Demaille <akim@epita.fr>
8449 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8450 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8451 configure.ac.
8452 * tests/aclocal.m4: Remove, as it is no longer used.
8454 2001-11-13 Akim Demaille <akim@epita.fr>
8456 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8457 variable names when referring to a single test group, or to
8458 `suite' when referring to the whole test suite.
8459 `at_last_test' is removed: m4 compute at_format itself.
8460 (at_stdout, at_stder1, at_stderr): New variables.
8461 (AT_CHECK): Use them.
8463 2001-11-13 Akim Demaille <akim@epita.fr>
8465 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8466 in PATH.
8467 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8468 Do it as soon as a test fails, don't wait till the end of the test
8469 suite.
8470 Don't remove $as_me.[0-9]*, since these files no longer exist.
8472 2001-11-13 Akim Demaille <akim@epita.fr>
8474 * tests/tools.at: Use absolute paths, since we are no longer run
8475 in place.
8477 2001-11-13 Akim Demaille <akim@epita.fr>
8479 Now that tests are running in their own private dir, there is no
8480 need to list the files to remove at the end of tests groups.
8482 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8483 (AT_data_files, at_data_files): Remove.
8484 (AT_CLEANUP, AT_DATA): Simplify.
8485 (AT_INIT): Adjust.
8486 Remove the group dir if !debug && !failed.
8487 * tests/atspecific.m4: Adjust.
8489 2001-11-13 Akim Demaille <akim@epita.fr>
8491 Start a new layout for Autotest: `testsuite' creates
8492 `testsuite.dir' in which the at-check-line etc. files are to be
8493 found, and `testsuite.dir/003' where the test group 3 is run.
8495 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8496 at_check_line_file, at_format, at_test_normalized, at_group_dir
8497 are new variables.
8498 Create the directories.
8499 Use absolute paths for at- files.
8500 (AT_CHECK): Adjust.
8502 2001-11-11 Michael Matz <matz@kde.org>
8504 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8505 (m4_car2): New.
8506 (m4_car): Properly quote arguments.
8508 2001-11-13 Akim Demaille <akim@epita.fr>
8510 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8511 with stricter rules on LIBOBJS.
8513 2001-11-12 Paul Eggert <eggert@twinsun.com>
8515 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8516 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8517 __PROTOTYPES too.
8519 2001-11-12 Akim Demaille <akim@epita.fr>
8521 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8523 2001-11-12 Akim Demaille <akim@epita.fr>
8525 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8526 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8527 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8528 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8529 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8530 specify to what the macro should be defined (typically to 1).
8532 2001-11-12 Akim Demaille <akim@epita.fr>
8534 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8535 From Jim Meyering.
8537 2001-11-12 Akim Demaille <akim@epita.fr>
8539 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8540 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8541 definition used by Automake where LEX is +/- "${missing} lex" and
8542 `missing' itself contains variables.
8544 2001-11-12 Akim Demaille <akim@epita.fr>
8546 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8547 Now that M4sh pushes BODY, the comments were output at the end of
8548 the test suites.
8550 2001-11-08 Akim Demaille <akim@epita.fr>
8552 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8553 that we can trace macros from aclocal.m4.
8554 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8555 obsoleted, and redirect to the former anyway.
8556 Reported by Ralf Corsepius.
8558 2001-11-08 Akim Demaille <akim@epita.fr>
8560 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8561 processed only if present.
8562 * tests/torture.at (Configuring subdirectories): Use autoreconf
8563 instead of successive calls to autoconf.
8564 Add a nonexistent subdirectory to exercise the patch above.
8565 Reported by Ralf Corsepius.
8567 2001-11-08 Kevin Ryde <user42@zip.com.au>
8569 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8570 doesn't accept .S files.
8572 2001-11-07 Akim Demaille <akim@epita.fr>
8574 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8575 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8576 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8577 * bin/autom4te.in (warn_forbidden): New.
8578 (handle_output): Use it.
8579 Read m4_pattern_forbid with messages.
8581 2001-11-05 Akim Demaille <akim@epita.fr>
8583 * bin/autom4te.in (--normalize): Remove.
8584 * lib/autom4te.in: Adjust.
8586 2001-11-05 Akim Demaille <akim@epita.fr>
8588 * tests/Makefile.am (testsuite): Rename this target as...
8589 ($(TESTSUITE)): this.
8590 From Nicolas Joly.
8592 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8594 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8595 the --prefix option, also remove it's argument.
8597 2001-11-05 Akim Demaille <akim@epita.fr>
8599 * doc/autoconf.texi (testsuite Invocation): Update.
8600 (Writing testsuite.at): Update.
8602 2001-11-03 Akim Demaille <akim@epita.fr>
8604 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8606 2001-11-03 Akim Demaille <akim@epita.fr>
8608 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8609 (&file_name_is_absolute): New, wrappers around routines from
8610 File::Spec.
8611 Use and export them.
8612 (&find_configure_ac): Optionally take a directory where to look at.
8613 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8614 the arguments.
8615 Default @ARGV to `.', not find_configure_ac.
8616 (&autoreconf): Argument is a directory.
8617 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8618 * doc/autoconf.texi (autoreconf Invocation): Update.
8620 2001-11-03 Akim Demaille <akim@epita.fr>
8622 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8623 (@export_forward_subs): New.
8624 Add basename, dirname, and fileparse.
8625 (@EXPORT): Adjust.
8626 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8627 Don't look for aclocal flags if we already know aclocal is not
8628 used.
8629 Move aclocal.m4t only if it exists.
8630 Reported by Ezra Peisach.
8632 2001-11-03 Akim Demaille <akim@epita.fr>
8634 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8635 passed on command line, defaulting to ./configure.ac if present.
8636 (&maybe_autoreconf, File::Find): Remove, unused.
8637 (&autoreconf): If autoconf is not used, don't try to trace.
8639 2001-11-02 Akim Demaille <akim@epita.fr>
8641 * configure.ac: Bump to 2.52g.
8643 2001-11-02 Akim Demaille <akim@epita.fr>
8645 Version 2.52f.
8647 2001-11-02 Akim Demaille <akim@epita.fr>
8649 * config/config.guess, config/config.sub, doc/standards.texi:
8650 * config/lispdir.m4: Update from masters.
8651 * configure.ac: Bump to 2.52f.
8653 2001-11-02 Akim Demaille <akim@epita.fr>
8655 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8656 Don't run aclocal when aclocal.m4 is not from aclocal.
8657 From Ezra Peisach.
8658 Don't run libtoolize and gettextize if --install is not given.
8660 2001-11-01 Paul Eggert <eggert@twinsun.com>
8662 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8663 be invoked before _AS_LINENO_PREPARE.
8664 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8665 than character ranges.
8667 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8668 invoking AS_BASENAME. Set the locale variables to 'C' if
8669 possible, as POSIX requires this to get the traditional
8670 behavior.
8671 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8673 2001-10-31 Paul Eggert <eggert@twinsun.com>
8675 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8676 with {}, as that triggers a bug in Bash 2.05.
8678 (_AS_LINENO_PREPARE): Use Sed rather than
8679 Awk. Fix the sed prepass to work even if there are multiple
8680 instances of $LINENO on the same line. Do not substitute for
8681 other variables like $LINENOT. Do not check file dates; such a
8682 check is unreliable on sufficiently fast machines, and removing
8683 the check makes the code simpler and more reliable. Check for
8684 output and chmod failures.
8686 * doc/autoconf.texi (Special Shell Variables): Document
8687 the above.
8689 2001-10-31 Akim Demaille <akim@epita.fr>
8691 * tests/Makefile.am (atconfig): Remove this target, Automake
8692 handles it now.
8694 2001-10-31 Akim Demaille <akim@epita.fr>
8696 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8697 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8698 provided, while it is optional.
8699 * configure.ac: Adjust.
8701 2001-10-26 Paul Eggert <eggert@twinsun.com>
8703 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8704 lib/Autom4te/Struct.pm:
8705 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8706 with 5.005_02.
8708 * doc/autoconf.texi (Special Shell Variables): Document some
8709 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8711 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8712 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8713 eval $LINENO is not portable in practice.
8715 2001-10-24 Akim Demaille <akim@epita.fr>
8717 * lib/Autom4te/General.pm (backname): New.
8719 2001-10-24 Akim Demaille <akim@epita.fr>
8721 * m4/: Remove, merged into...
8722 * config/: here.
8724 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8726 * doc/autoconf.texi (Shellology): Mention the problems with bash
8727 2.05's use of ANSI quoting in its `set' builtin.
8729 2001-10-22 Paul Eggert <eggert@twinsun.com>
8731 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8732 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8733 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8734 POSIX decided to standardize on the int flavor of strerror_r.
8735 Always do char* test, as there's no reason not to.
8736 Assign to a char* var, to catch strerror_r that returns int*.
8738 * doc/autoconf.texi (Particular Functions):
8739 Document the above changes. Also, document the fact that
8740 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8742 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8744 2001-10-20 Akim Demaille <akim@epita.fr>
8746 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
8747 the executable was missing from the log.
8749 2001-10-20 Akim Demaille <akim@epita.fr>
8751 * lib/Autom4te/General.pm (&update_file): If destination is
8752 unchanged, remove the source.
8753 (&up_to_date_p): Don't be verbose, be debug.
8754 * bin/autoreconf.in: No longer support --m4dir.
8755 (&autoreconf): Display the full path of the configure.ac we are
8756 studying.
8757 Trace it only once.
8758 Be sure to honor --force with gettextize.
8759 Always run aclocal.
8760 * doc/autoconf.texi: Adjust.
8762 2001-10-20 Akim Demaille <akim@epita.fr>
8764 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8765 Remove, dead.
8766 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8767 `intl' is already present, as it refuses unless --force.
8768 (&parse_args): Use -I, --include instead of the old Autoconf
8769 options.
8770 ($localdir, $autoconf_dir): Remove.
8771 (@include): New.
8772 (&maybe_autoreconf): New, to preserve $_ for File::Find.
8774 2001-10-19 Jens Petersen <petersen@redhat.com>
8776 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

8779 2001-10-19 Akim Demaille <akim@epita.fr>
8781 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
8782 file in @configure_input@.
8783 Don't mention `automatically' in addition to `generated'.
8784 * tests/torture.at (#define header templates): Adjust.
8786 2001-10-19 Akim Demaille <akim@epita.fr>
8788 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
8789 comment, explain how to install automatic mode selection.
8790 From Russ Allbery.
8792 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
8794 * bin/autoreconf.in (autoreconf): Display the path to the
8795 configure.ac being studied.
8797 2001-10-18 Paul Eggert <eggert@twinsun.com>
8799 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
8800 long, to work around a bug in the HP C compiler version HP92453-01
8801 B.11.11.23709.GP.
8803 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
8804 (AS_BASENAME_EXPR): New macro.
8805 (AS_BASENAME_SED): Do not assume GNU sed semantics.
8806 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
8807 and fall back on 'sed' only if the other two fail. This makes
8808 AS_BASENAME act more like AS_DIRNAME.
8809 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
8810 contains white space.
8811 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
8812 Use AS_DIRNAME, since I think it's now DOS-friendly.
8813 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
8814 Allow "dirname //FOO" to return either / or //, as POSIX allows
8815 either behavior.
8817 2001-10-10 Akim Demaille <akim@epita.fr>
8819 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
8820 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
8821 From Eric Sharkey.
8823 2001-10-10 Akim Demaille <akim@epita.fr>
8825 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

8829 2001-10-10 Akim Demaille <akim@epita.fr>
8831 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

8849 (Autoconf): Use it.

8868 2001-10-08 Akim Demaille <akim@epita.fr>
8870 * bin/autoreconf.in: Rewrite in Perl.
8871 * configure.ac: Adjust.

8905 * tests/m4sh.at: Don't rely on Autoconf macros.
8906 (DIRNAME_TEST): Also exercise the expr variant.
8907 * tests/m4sugar.at, tests/atspecific.m4 (AT_CHECK_M4SUGAR): The
8908 preferred M4sugar extension is now `.4s'.

8916 * lib/autoconf/general.m4 (AS_DEFUN, AC_DEFUN_ONCE, AC_BEFORE)
8917 (AC_REQUIRE, AC_PROVIDE, AC_PROVIDE_IFELSE): Be exact copy of the
8918 M4sugar peer, i.e., drop the `AC_PROVIDE_$1' broken marker.
8920 2001-10-08 Akim Demaille <akim@epita.fr>
8922 Use `add-log-current-defun-function' for ChangeLog creation.
8923 Suggested by Tom Tromey.
8925 * lib/emacs/autotest-mode.el (autotest-mode-map): New.
8926 (autotest-mode): Adjust.
8927 * lib/emacs/autoconf-mode.el (autoconf-mode-map): Modernize, map

8939 (AT_INIT): Replace AC_PLAIN_SCRIPT with AS_INIT invocation,
8940 include handle the m4_pattern_*, no longer push the
8941 BODY diversion nor set the /bin/sh line, AS_INIT does it.

8944 * tests/tools.at (AT_DATA_FORBIDDEN): New.

8950 * doc/autoconf.texi (config.status Invocation):
8951 CONFIG_SHELL defaults to a shell that supports LINENO if available.
8953 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
8954 shell does not support LINENO, and if CONFIG_SHELL is unset or
8955 empty, and if we can find a shell that does support LINENO,
8956 then set CONFIG_SHELL to that shell and then re-execute
8957 ourselves with CONFIG_SHELL.
8959 2001-10-05 Paul Eggert <eggert@twinsun.com>
8961 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
8962 doesn't exist. Remove *.tmp, as a .tmp file is created during the
8963 build of $(TESTSUITE).
8965 2001-10-05 Akim Demaille <akim@epita.fr>
8967 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

8985 2001-10-05 Akim Demaille <akim@epita.fr>
8987 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): New, extracted from...
8988 (AS_SHELL_SANITIZE): here. Use it.
8989 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
8990 From Paul Eggert.
8992 2001-10-04 Akim Demaille <akim@epita.fr>
8994 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
8995 combination of Awk and sed to replace $LINENO.
8997 2001-10-02 Paul Eggert <eggert@twinsun.com>
8999 * doc/autoconf.texi (Limitations of Builtins): You can't use
9000 "source"; it's not portable. Remove confusing and
9001 somewhat-incorrect example involving "." and "/".
9003 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
9004 compatibility with POSIX shells.
9006 2001-10-02 Akim Demaille <akim@epita.fr>
9008 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
9009 instead of exec'ing to preserve $0 and $@.
9011 2001-10-01 Akim Demaille <akim@epita.fr>
9013 * tests/testsuite (AT_INIT) <at_pass_list>: New.

9030 2001-09-30 Paul Eggert <eggert@twinsun.com>
9032 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
9033 Don't use nested parenthesization. This patch was originally
9034 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
9035 but somehow it didn't get incorporated then.
9036 * doc/autoconf.texi (Limitations of Usual Tools):
9037 Clarify remark about sed and nested parenthesization.
9039 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
9040 Report an error if the size cannot be determined even though
9041 the type exists.
9042 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9043 Check for `expr' arithmetic overflow, and for compilation failure,
9044 and invoke a new argument $4 if either is discovered.
9045 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9046 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9048 2001-09-28 Akim Demaille <akim@epita.fr>

9062 2001-09-27 Akim Demaille <akim@epita.fr>
9064 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that

9068 status when executing the ACTION-IF-FALSE.
9069 * tests/base.at (AC_TRY_*): Rename as...

9074 (Broken/missing compilers, AC_PROG_CPP with warnings)
9075 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
9076 * tests/c.at (Extensions, C keywords)
9077 (Broken/missing compilers, AC_PROG_CPP with warnings)
9078 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
9079 (AC_PROG_CPP requires AC_PROG_CC): here and...
9080 * tests/fortran.at (GNU Fortran 77): there.
9081 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9082 AC_TRY_RUN is about compilation, not shell commands.
9083 (Test Programs): AC_TRY_RUN works as used to be advertised.
9085 2001-09-27 Akim Demaille <akim@epita.fr>
9087 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9088 Raja R Harinath:
9089 Be sure to detect when $LINENO always returns the same value.
9090 Look for the original script, basename($0) is certainly not
9091 enough.
9092 Pass the CLI arguments to `$as_me.lineno'.
9094 2001-09-25 Akim Demaille <akim@epita.fr>
9096 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
9097 Be sure the close and reopen the LOG fd before and after using tee

9101 2001-09-23 Akim Demaille <akim@epita.fr>
9103 * bin/autom4te.in (parse_args): There can be several invocations
9104 of --language now.
9106 2001-09-23 Akim Demaille <akim@epita.fr>
9108 * doc/autoconf.texi (Top): Wrap in @ifnottex.
9110 2001-09-23 Akim Demaille <akim@epita.fr>
9112 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
9113 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
9114 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
9115 builddir, buildpath, top_builddir, and top_buildpath.
9116 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
9117 the current directory.
9118 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
9119 variables *before* changing the current directory.
9120 Skip nonexistent dirs.
9121 * doc/autoconf.texi (Preset Output Variables): Document these
9122 variables.
9124 * lib/autotest/general.m4: Do not reset AT_victims.
9125 Don't compute at_srcdir nor at_top_srcdir.
9127 * tests/tools.at: Hence use top_srcdir.
9129 * tests/Makefile.am, tests/autoconf, tests/autoheader,
9130 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
9131 Remove.
9132 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
9133 * tests/wrapsh.in, tests/autoupdate.in: New.
9134 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
9135 * configure.ac: Build the position independent wrappers.
9137 * man/Makefile.am: Now that test wrappers are position
9138 independent, use them and drop dark envvar magic.
9140 2001-09-23 Akim Demaille <akim@epita.fr>
9142 * doc/autoconf.texi (Common Shell Constructs): Rename as...
9143 (Programming in M4sh): this.
9144 Promote to @section.
9146 2001-09-23 Akim Demaille <akim@epita.fr>
9148 * lib/autotest/general.m4 (AT_INIT): Dump config.log last.

9158 2001-09-23 Akim Demaille <akim@epita.fr>
9160 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix shell
9161 over-escaping.

9166 * bin/autom4te.in ($language): Move to...
9167 (parse_args): here.
9168 Handle --language in languages.
9169 * lib/autom4te.in (Automake-selections, Autoheader-selections)

9171 (Autoconf): Adjust.
9173 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
9175 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,
9176 * m4/install-sh.m4, m4/missing.m4, m4/sanity.m4, m4/strip.m4: Updated
9177 to match current versions from CVS Automake.
9179 2001-09-23 Alexandre Duret-Lutz <duret_g@epita.fr>
9181 * doc/autoconf.texi (Special Shell Variables): Add pdksh output
9182 for $LINENO.
9184 2001-09-22 Akim Demaille <akim@epita.fr>
9186 * lib/autoconf/autotest.m4: Create `package.m4'.
9187 * tests/Makefile.am (package.m4): Remove.
9189 2001-09-22 Akim Demaille <akim@epita.fr>
9191 Rely on `$LINENO' when possible instead of `__oline__'.
9193 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
9194 `$LINENO' support replacement when not supported.
9195 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
9196 them explicitly to be sure they are not output before this section
9197 (via m4_require). Cosmetic only.
9198 * lib/autoconf/c.m4, lib/autoconf/general.m4,
9199 * lib/autoconf/programs.m4: Replace all the occurrences of
9200 `__oline__' with `$LINENO'.
9201 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
9203 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
9205 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
9206 character (u: -> ue) in a code comment.
9207 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
9208 it works.
9210 2001-09-21 Akim Demaille <akim@epita.fr>
9212 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9213 Suggested by Jim Meyering.
9215 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9217 * lib/autoconf/programs.m4: Use extensions listed in
9218 $ac_executable_extensions when looking for programs.
9220 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9222 * lib/autoconf/general.m4: Fix a small Englisho.

9224 setting up ac_dir_suffix and ac_top_builddir.
9225 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
9227 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9229 * doc/autoconf.texi (File System Conventions): Clarify the use of
9230 PATH_SEPARATOR.
9231 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9232 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9233 be used instead of ':'.
9234 * lib/autotest/general.m4: Replace occurrences of ':' in
9235 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9237 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9239 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
9240 arguments. Fixed a typo.
9242 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9244 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9245 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9247 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9249 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
9250 * bin/autoupdate.in: Ditto.
9251 * bin/autoheader.in: Reworded a few comments.
9252 * bin/autoconf.in: Reworded help text for a few options.
9253 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,

9256 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9258 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9259 already have $file). Set output files to binary mode (helps avoid
9260 CR issues on DOSish systems).
9262 2001-09-19 Akim Demaille <akim@epita.fr>
9264 * lib/autotest/general.m4: Englishoes.
9265 From Tim Van Holder and Alexey Mahotkin.
9267 2001-09-18 Paul Eggert <eggert@twinsun.com>
9269 * doc/autoconf.texi (Common Shell Constructs): New node,
9270 documenting AS_DIRNAME.
9271 (Limitations of Usual Tools): Refer to it when discussing dirname.
9272 Also, update discussion of POSIX standard to reflect latest draft.
9274 * lib/autoconf/c.m4:
9275 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9277 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9278 Do not pass a first argument with leading '-'
9279 to expr, by parenthesizing initial integers that might be negative.
9281 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9282 now merely checks whether it is an error to pass an argument
9283 to getpgrp.
9285 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9286 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9287 whether it is a (compile-time) error to pass an argument to
9288 getpgrp. This simpler test supports the revised documentation,
9289 and is all that AC_FUNC_GETPGRP's users really need.
9291 2001-09-18 Akim Demaille <akim@epita.fr>
9293 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9295 2001-09-18 Akim Demaille <akim@epita.fr>
9297 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
9298 `{}'.
9299 * lib/autotest/general.m4 (AT_INIT): Adjust.
9301 2001-09-18 Paul Wagland <paul@wagland.net>
9303 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9304 correctly.
9305 Add test for AS_BASENAME.
9306 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9307 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9308 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9309 * tests/base.at: Fixed the expected responses. The old ones were
9310 one line out...
9311 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9312 the documentation claims it should (and how it behaved in 2.13).
9314 2001-09-18 Akim Demaille <akim@epita.fr>
9316 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9317 the AC_CONFIG_COMMANDS invocation.
9318 This also solves the name clash problems.
9319 Don't set the package's ID.
9320 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9321 No longer to be shipped.
9322 (version.in): Remove.
9323 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9324 * lib/autoconf/status.m4: Adjust.
9325 Use `m4_PACKAGE_STRING'.
9326 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9327 the only optional argument is the name of the test suite.
9328 Expect `package.m4' to define the package signature.
9329 * lib/autom4te.in (Autotest): Add `package.m4?'.
9330 * tests/Makefile.am (package.m4): New.
9331 * tests/suite.at: ifnames is a victim.
9333 2001-09-18 Akim Demaille <akim@epita.fr>
9335 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9336 AC_LIBSOURCE, AC_CONFIG_FILES.
9337 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9338 program version string doesn't match the package's.
9339 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9340 after `(cached)'.
9342 2001-09-17 Paul Eggert <eggert@twinsun.com>
9344 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9345 Allow expression to return any value that can fit into unsigned long
9346 (not int, as before). Check for output errors.
9348 2001-09-17 Bruno Haible <haible@ilog.fr>
9350 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9351 Always include <stdio.h> and <stdlib.h>. Evaluate
9352 the expression in an extra function before these includes. Call
9353 fprintf "%d" only after ensuring the argument is of type 'int'.
9354 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9356 2001-09-17 Paul Eggert <eggert@twinsun.com>
9358 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9359 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9360 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9361 when they don't exist.
9363 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9364 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9365 need it.
9367 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9368 version with the version used by fileutils 4.1, except use

9526 2001-09-05 Akim Demaille <akim@epita.fr>

9529 the maintainer is dumb enough to do that...
9531 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9532 excellence in M4 quotation: consider `__file__' is active.
9534 And BTW, when invoking m4, pass the --include in the right order:
9535 the wrong one.
9537 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
9538 4m.

9560 2001-09-05 Akim Demaille <akim@epita.fr>

9565 New, extracted from main.
9566 Use IO::File wherever possible.
9567 (input.m4): Be constant, use -I instead of hard coding $tmp.
9568 Therefore be a quoted heredoc.
9569 Don't invoke `_au_disable', since ac was not loaded, but just
9570 `unm4.m4'.
9572 2001-08-31 Akim Demaille <akim@epita.fr>
9574 Version 2.52d.

9597 2001-08-31 Akim Demaille <akim@epita.fr>
9599 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9600 (testsuite Scripts): There is no such thing as `atconfig.in'.
9601 And actually one diagram is missing: test suite runtime.
9603 2001-08-31 Akim Demaille <akim@epita.fr>
9605 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9606 inverse order.
9608 2001-08-31 Akim Demaille <akim@epita.fr>
9610 * bin/autoupdate.in (@include): `installcheck' revealed the path
9611 to m4sugar was lacking!
9613 2001-08-31 Akim Demaille <akim@epita.fr>
9615 * man/Makefile.am (.x.1): We really have to pass
9616 autom4te_perllibdir.
9618 2001-08-31 Akim Demaille <akim@epita.fr>
9620 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

9622 run is stupid.
9624 2001-08-31 Akim Demaille <akim@epita.fr>
9626 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9627 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9628 Use directly autom4te, not autoconf.

9652 `print $out' doesn't print `$_' but `$out'.
9653 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9654 (autoheader): Pass --force since the test suite goes too fast for
9655 the time stamps.
9656 Adjust to the new autoheader messages.
9658 2001-08-31 Akim Demaille <akim@epita.fr>

9669 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9670 Drop AC_MACRODIR dead for real.
9671 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9672 `autoheader: `config.hin' is created'.
9673 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9675 2001-08-31 Akim Demaille <akim@epita.fr>
9677 * bin/autoheader.in: Rewrite in Perl.

9680 2001-08-31 Akim Demaille <akim@epita.fr>

9683 Map --localdir, --autoconf-dir onto it.
9684 Forward autom4te's options instead of interpreting them.
9685 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9686 There is no such envvar since the inception of autom4te.cfg.
9687 * bin/autom4te.in (&parse_args): Uniquify `@include'.
9688 * bin/autoupdate.in: Adjust, and perform more control.

9692 2001-08-31 Akim Demaille <akim@epita.fr>

9695 * bin/autom4te.in (&find_file): Support `FILE?' standing for

9698 (&parse_args): Adjust.
9699 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9701 2001-08-31 Akim Demaille <akim@epita.fr>

9704 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9705 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9706 installed peer executables, only PATH is allowed to resolve it.
9707 Pass `autoconf_dir' via options, not via invisible envvars.
9708 * lib/Autom4te/General.pm (&find_peer): Remove.
9709 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9710 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9711 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9712 find the executables for it.
9713 * tests/Makefile.am: Major cleanup. Too lazy to document...
9714 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9715 We only need PERL.
9716 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9717 indeed related to running the test suite, while passing
9718 --autoconf-dir and others is related to running non installed
9719 Autoconf executables. So don't do that, leave it to...
9720 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9721 * tests/autoscan: New.
9722 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

9739 Suggested by Paul Eggert.
9741 2001-08-29 Akim Demaille <akim@epita.fr>
9743 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9744 download in a tmp dir.
9746 2001-08-29 Akim Demaille <akim@epita.fr>
9748 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

10294 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10295 magic values from an object file when cross-compiling.
10296 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10298 2001-08-10 Akim Demaille <akim@epita.fr>
10300 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10301 effects.
10302 Suggested by Russ Allbery.
10304 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10306 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10307 current $prefix to the sub-configures.
10309 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10311 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10312 extension (needed on BeOS). Reported by Guido van Rossum.
10314 2001-08-09 Akim Demaille <akim@epita.fr>
10316 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10318 2001-08-07 Akim Demaille <akim@epita.fr>
10320 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10321 removed.
10322 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10323 No need to remove the files before and after the each test, before
10324 each test and at the end of the suite is enough.
10325 Display only the children `times', not the shell's.
10326 If the test failed or was skipped, at-times is not available.
10328 2001-08-07 Akim Demaille <akim@epita.fr>
10330 Always produce testsuite.log, including when there are no
10331 failures. This helps getting information on skipped tests, and
10332 duration of the tests. Err, implement the latter btw.
10334 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10335 Dump information on the first run of each test.
10336 (AT_CLEANUP): Create `at-times' containing the duration of the
10337 test group.
10339 2001-08-07 Akim Demaille <akim@epita.fr>
10341 The use of `dumpstat' revealed that `len' was used although it
10342 should not. m4_text_wrap was using it, but in the Autoconf world
10343 where it is legal. Hence (i) test M4sh in its own world, not
10344 Autoconf's, and (ii), ahem, fix the bug :)
10346 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10347 does not like `' instead of [].
10348 (AT_INIT): Forbid `^_?AT_'.
10349 And don't output such tokens.
10350 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10351 `script.as', and `autom4te.cache'.
10352 Remove `empty' and `macro' which are no longer used.
10353 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10354 * tests/m4sugar.at: Use it.
10355 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10357 2001-08-07 Akim Demaille <akim@epita.fr>
10359 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10361 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10363 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10365 2001-08-04 Akim Demaille <akim@epita.fr>
10367 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10368 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10369 AC_TRY_LINK.
10370 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10371 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10372 (AC_F77_MAIN): Likewise.
10374 2001-08-04 Akim Demaille <akim@epita.fr>
10376 Don't rely on M4sugar outputting the patterns in files, since we
10377 might process the output _without_ running m4, hence without these
10378 files.
10380 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10381 * bin/autom4te.in (@Request::includes): Remove, unused.
10382 (@Request::source): Rename as...
10383 (@Request::input): this.
10384 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10385 (&handle_output): Fetch the patterns from the traces.
10386 `$forbidden' and `$allowed' are constant: use m//o.
10387 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10388 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10390 2001-08-04 Akim Demaille <akim@epita.fr>
10392 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10393 autoconf', i.e., in addition to caching traces, cache the output.
10395 * bin/autom4te.in (Request::cache): Rename as...
10396 (Request::id): this.
10397 ($cache, $icache, $tcache, $ocache): New.
10398 (&handle_m4): Save M4 output in the cache instead of $tmp.
10399 (&handle_output): Adjust.
10400 (&up_to_date_p): Check that the output cache is up to date too.
10401 (top level): Run `&handle_m4' iff force or the cache is invalid.
10402 Run `&handle_output' if the output cache is more recent.
10404 2001-08-04 Akim Demaille <akim@epita.fr>
10406 * bin/autom4te.in ($force): New.
10407 (&parse_args, &print_usage): -f, --force is a new option.
10408 (&handle_output): CPP directives might have spaces after `#'.
10409 (&parse_args): The first file only can be frozen.
10411 2001-08-04 Akim Demaille <akim@epita.fr>
10413 Don't let autom4te compute the `include' traces several times:
10414 first check that the trace cache file is up to date, and then
10415 compare its timestamp with that of the output.
10417 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10418 the preamble. Don't require 5.005 as Autom4te::General does it,
10419 and better yet (use `use', not `require'!).
10420 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10421 Class::Struct as Autom4te::Struct.
10422 * lib/Autom4te/General.pm (File::stat): Use it.
10423 (&mtime): New, export it.
10424 * bin/autom4te.in: Use it.
10425 Declare `$req' is invalid if it is outdated.
10426 Don't declare it valid before saving it if something went wrong.
10428 2001-08-04 Akim Demaille <akim@epita.fr>
10430 Autom4te shall not encode Autoconf data, and preselecting traces
10431 must be proposed to the users.
10433 * bin/autom4te.in (@required_trace): Remove.
10434 (@preselect): New.
10435 (&parse_args, &print_usage): -p, --preselect is a new option.
10436 (&up_to_date_p): Adjust.
10437 * bin/autoconf.in: Preselect some Autoconf macros.
10439 2001-08-04 Akim Demaille <akim@epita.fr>
10441 * tests/tools.at (autoconf --trace: user macros): Check traces on
10442 macros invoked without arguments, and macros invoked with multiple
10443 lines arguments.
10445 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10447 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10448 arguments.
10450 2001-08-03 Akim Demaille <akim@epita.fr>
10452 * bin/autoconf.in ($@): Work around the usual sh bug.
10453 From Nicolas Joly.
10455 2001-08-03 Akim Demaille <akim@epita.fr>
10457 Clean up the handling of the M4 builtins tracing exception.
10459 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10460 trace requests.
10461 (@m4_builtins): Rename as...
10462 (@m4_builtin): this.
10463 (%m4_builtin_alternate_name): New.
10464 (&parse_args): Complete the trace requests with alternate names.
10465 (&handle_traces): Hence no longer do it here.
10466 (&trace_requests): Remove, unused.
10468 2001-08-03 Akim Demaille <akim@epita.fr>
10470 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10471 m4_if, and m4_wrap.
10473 2001-08-03 Akim Demaille <akim@epita.fr>
10475 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10476 (m4_divert_pop): Dump the whole diversion stack when a diversion
10477 mismatch happens.
10478 * bin/autom4te.in (&handle_output): Remember of the first
10479 occurrence of a possibly undefined macro, not the last.
10480 Complain about the possibly undefined macros in the same order as
10481 the appear in the output.
10482 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
10483 * tests/tools.at (autoconf: forbidden tokens, basic)

10485 autoconf's stderr, as it is now deterministic.
10486 Check that `dnl' is caught.
10488 2001-08-01 Akim Demaille <akim@epita.fr>
10490 * configure.ac: Bump to 2.52c.

10508 `END', as `Autom4te::General::END' will be triggered.

10510 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

10945 cross-language link tests can be performed successfully.
10946 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
10947 after $LIBS, for consistency; this should be the general rule since
