3 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4 seen, invoke libtoolize with `--ltdl' argument.
5 * lib/autom4te.in (Autoreconf-preselections): Adjust.
7 Suggested by Eric Blake.
9 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
11 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
12 reported by Ralf Wildenhues.
13 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.

23 2006-06-05 Stepan Kasal <kasal@ucw.cz>
25 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
26 message issued by AC_REQUIRE.
27 * tests/m4sugar.at: Check m4_require's error message.
28 * tests/base.at: Check AC_REQUIRE's error message.
29 * tests/local.at (AT_CHECK_M4): New macro, almost identical
31 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
33 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
34 `expout' as the last parameter.
35 * tests/tools.at: Adapt to the above change.
37 2006-06-04 Stepan Kasal <kasal@ucw.cz>
39 * doc/autoconf.texi (Limitations of Usual Tools): Correct
40 information about race-free implementations of mkdir.
42 2006-06-04 Eric Blake <ebb9@byu.net>

47 * doc/autoconf.texi (autom4te Invocation): Likewise.
49 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
51 * NEWS: GNU make now recommended for VPATH builds.
52 Mention that some macros are now documented to be obsolescent.
54 Prefer "current" to "modern" to describe
55 currently-used (albeit perhaps old-fashioned) hosts.
56 Mention which ancient features no longer need to be worried about.
57 setgid -> set-group-ID
58 setuid -> set-user-ID (these are the Posix terms)
59 Fix some misuses of "only".
60 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
61 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
62 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
63 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
64 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
65 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
66 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
67 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
68 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
69 Mention that these macros are obsolescent.
70 (Installation Directory Variables): shall -> should
71 (File Descriptors): Mention that 0, 1, 2 might get reopened.
72 Mention that it's now safe to use 3 and 4.
73 (Limitations of Usual Tools): cp -r is now specified by Posix.
74 Omit longwinded and obsolescent discussion of cp -f.
75 Modernize discussion of expr, ls.
76 (Limitations of Make): Modernize discussion of VPATH builds.
77 Mention $? as a workaround in some cases.
78 * doc/install.texi (Basic Installation):
79 Mention "./configure; make; make install" first. Be more
80 specific about why this file is generic. Remove unnecessary
81 parens. Remove misleading "only". Remove obsolete advice
82 about csh. Don't say "configure" takes awhile; say it
83 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
84 and CC=c99 rather than CC=c89, as these are blessed by current
85 Posix. Recommend GNU make if doing a VPATH build.
87 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
89 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
90 examples involving shell prompts.
92 2006-06-02 Stepan Kasal <kasal@ucw.cz>
93 and Paul Eggert <eggert@cs.ucla.edu>
95 * doc/autoconf.texi (Here-Documents): Add details about the
96 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
97 use "here-documents" instead of "here documents".
99 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
101 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
103 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
105 * doc/autoconf.texi (File System Conventions): Warn about ":"
106 anywhere in directory names.
108 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
110 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
111 about quoting the case statement, just in case.
112 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
113 was fixed in ksh93g; reported by Ralf Wildenhues.
115 2006-05-31 Stepan Kasal <kasal@ucw.cz>
117 * doc/autoconf.texi (System Services): Do not document
118 overriding EXEEXT via ac_cv_exeext=ext.
119 (Particular Programs) <AC_PROG_MKDIR_P>:
120 Document that ${MKDIR_P} understands --.
121 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
124 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
126 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
127 argument with leading hyphen. Problem reported by Paul Eggert.
129 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
131 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
132 about quoting ac_try: quote all of it, if any of it seems suspicious.
133 This means we don't have to worry about ${ or sed any more.
134 Also, double-quote the case statement, to work around misuses via
135 underquoting as reported by Ralf Wildenhues in
136 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
137 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
138 undocumented and dangerous macro.
139 Problem reported by Ralf Wildenhues in
140 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
142 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
144 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
145 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
146 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
148 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
150 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
151 since evidently some packages rely on the old, broken behavior.
152 Problem reported by Ralf Wildenhues in
153 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
154 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
155 pre-2006-05-26 definitions, but leave in the comments that
156 these macros are dangerous and should not be used.
157 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
158 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
159 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
160 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
161 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
163 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
165 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
166 the use of 'tr', since this is our only use of 'tr'.
168 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
169 and Paul Eggert <eggert@cs.ucla.edu>
171 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
172 Don't assume 'grep' works on long lines, since AIX grep doesn't.
174 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
176 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
177 the output file in the `${datarootdir}' test.
179 2005-05-28 Stepan Kasal <kasal@ucw.cz>
180 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
182 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
183 mention of `datarootdir' in the input file(s), but literal
184 `${datarootdir}' in the output file, and we haven't warned yet,
185 then warn as well: the user may have (erroneously) used
186 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
187 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
188 * tests/torture.at (datarootdir workaround): Extend this test.
191 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
192 and Paul Eggert <eggert@cs.ucla.edu>
194 * doc/autoconf.texi (autoheader Invocation): The first argument to
195 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
196 alternatives and clear up the language a bit.
198 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
200 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
201 ac_config_guess, ac_config_sub, ac_configure.
202 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
203 Fix typo that prevented an unnecessary space from being removed.
204 Problems reported by Ralf Wildenhues in:
205 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
207 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
209 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
210 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
211 Don't use the term "thread-safe" to talk about mkdir race
212 conditions, since the problem is more a process than a thread
213 issue. Problem reported by Stepan Kasal in:
214 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
215 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
216 the test for 'install' more closely. Look at MKDIR_P first.
217 Look in the PATH, and at /opt/sfw/bin.
218 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
219 Don't bother to try mkdir -p, since we already check mkdir --version;
220 just look at the version number. (There's no easy way to check
221 for race-free implementations.)
222 * tests/tools.at (autoconf: subdirectories): Adjust to above
223 changes, since MKDIR_P now might end in "/mkdir -p".
225 * doc/autoconf.texi (autoheader Invocation): Mention that the
226 first arg of AC_DEFINE_UNQUOTED must be a literal.
227 Problem reported by Ben Pfaff in
228 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
230 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
231 * doc/autoconf.texi (Special Chars in Variables): New section.
232 (Preset Output Variables): Warn about special chars in CPPFLAGS.
233 (Installation Directory Variables): Quote $(datadir) better.
234 (Limitations of Builtins): Describe some of eval's trickiness.
236 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
237 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
238 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
239 in front of every arg, not just trailing args. Quote apostrophes.
240 (_AC_EVAL_ECHO): New macro.
241 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
242 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
244 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
245 exposed by quoting of eval argument. Put the command on line line
247 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
248 (_AC_PATH_X, AC_PATH_X): Quote more safely.
249 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
250 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
251 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
252 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
253 Use eval more safely.
254 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
255 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
257 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
258 lines, exposed by quoting of eval argument.
260 2006-05-26 Stepan Kasal <kasal@ucw.cz>
261 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
263 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
264 initialization of `ac_cv_exeext', do not override it if it was
265 already set, unless it was set to `no', for compatibility with
266 Autoconf-2.13, and comment this.
267 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
268 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
269 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
270 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
271 Document that this test may be overridden by setting
274 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
276 Revert these two patches:
278 2006-04-06 Eric Blake <ebb9@byu.net>
279 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
280 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
283 2006-04-01 Stepan Kasal <kasal@ucw.cz>
284 Clean up _AC_COMPILER_EXEEXT* macros.
285 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
286 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
287 ac_file to the name of the default output file and call
288 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
289 initial `rm' of the candidate files...
290 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
291 the same list in subsequent `rm' calls, and for the temporary
292 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
293 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
294 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
295 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
296 no longer needed) by libtool. Make it a cache check.
297 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
298 copied here by mistake.
299 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
301 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
302 _AC_COMPILER_OBJEXT directly.
303 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
305 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
307 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
308 Fix description of how the buggy `sed' works.
310 2006-05-25 Noah Misch <noah@cs.caltech.edu>
314 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
315 ENOLCK. Only mention `make -j' when applicable. Only raise
316 fatal errors when `make -j' is involved. Improve error message.
318 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
320 * doc/autoconf.texi (Here-Documents): We now know more about
321 the variable expansion in here documents bug.
322 Thanks to Tim Rice and Stepan Kasal.
324 * doc/autoconf.texi (Making testsuite Scripts): Add an example
325 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
327 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
329 * tests/autotest.at (Multiline command from M4 expansion):
330 No failure to be expected if the shell quotes newlines in
331 commands in the `set -x' output. Report by Tim Rice.
334 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
336 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
337 expansion in the here-documents used by config.status, as that
338 runs afoul of the Korn shell version M-12/28/93d bug described in
339 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
340 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
341 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
343 2006-05-23 Jim Meyering <jim@meyering.net>
345 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
346 Fix typo introduced with 2006-04-02 change. It reversed the sense
349 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
351 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
352 ac_dB slightly, to save bytes in the script.
353 Max out at 50 lines, rather than 96; this is more likely
354 (though not guaranteed) to avoid obscure 'sed' failures.
356 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
358 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
359 `tr -d -' as bad option argument. Work around this by deleting
360 an unrelated character.
361 Report by Tim Rice <tim@multitalents.net>.
363 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
364 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
365 Stepan Kasal <kasal@ucw.cz>
367 * doc/autoconf.texi (Particular Programs): Do not promise that
368 we always prefer the GNU version of the program, and that we
369 search according to PATH; both rules can have exceptions.
370 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
371 AC_PROG_SED. Move descriptions of limitations
372 to the Limitations of Usual Tools section.
373 (Limitations of Usual Tools) <sed>: Mention script length
374 limitations with Solaris /usr/ucb/sed.
375 <grep>: Fix wording for empty alternative. Mention that -c and
376 -l should not be combined, and that -E and -F should not be
379 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
380 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
382 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
383 limits in Solaris 8 /usr/ucb/sed by testing a long script.
385 2006-05-22 Stepan Kasal <kasal@ucw.cz>
387 * doc/autoconf.texi (Defining Symbols): Literal parameter of
388 AC_DEFINE is now passed to m4_pattern_allow.
389 * NEWS: Mention that; likewise for AC_SUBST.
390 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
391 the parameter to m4_pattern_allow.
392 * tests/tools.at: Add a check for that.
394 2006-05-22 Stepan Kasal <kasal@ucw.cz>
396 * lib/autoconf/status.m4: Fix typos.
398 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
400 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
401 only the files that this macro generates.
403 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
405 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
406 the HP-UX sed limitation of 99 commands, labels do not count.
407 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
409 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
411 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
413 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
414 Import the following fix from coreutils:
416 2006-01-13 Jim Meyering <jim@meyering.net>
418 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
419 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
420 not double-quote uses of that variable, to accommodate the rare
421 case in which getmntent is available in none of the libraries
422 checked. This happens at least on FreeBSD 5.0.
424 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
426 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
427 ac_config_guess, ac_config_sub, and ac_configure, since evidently
428 some other programs unwisely rely on these undocumented vars.
429 But put in warning comments about them.
430 Problem reported by Ralf Wildenhues in
431 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
432 * NEWS: Document that these variables are intended to go away.
434 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
436 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
437 and set the language to C++ (analogous to the equivalent Fortran
440 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
441 * doc/autoconf.texi (C++ Compiler): Document it.
442 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
445 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
447 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
448 that caused config.status to generate 100-command sed scripts; the
449 portable limit is 99.
451 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
453 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
454 variable `ac_d' instead of `d' to avoid infringing namespace.
455 Report by Ralf Menzel.
457 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
459 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
460 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
461 * tests/tools.at (autoconf: subdirectories): New test, taken from
462 the corresponding problem report by Ralf Wildenhues in:
463 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
465 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
466 Quote some uses of shell variables if they might suffer unexpected
467 globbing. This doesn't fix all instances of quoting problems that
468 I found, just the easy ones that look safe.
469 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
470 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
471 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
472 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.

478 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
480 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
482 * bin/autoreconf.in ($help): Reword according to the manual.
483 Suggested by Olly Betts.
485 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
486 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
488 * bin/autoreconf.in: Pass the directory argument to
489 `require_configure_ac'. Fix comment.
490 * tests/torture.at (Configuring subdirectories): Expose this.
491 Reported by Olly Betts.
493 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
495 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
496 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
499 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
500 `$configure_in' instead of `configure.in', to preserve
503 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
505 * config/config.guess, config/config.sub, config/texinfo.tex,
506 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
508 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
510 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
511 test for C99 conformance; (bool) 0.5 is an integer constant
512 expression, but (bool) -0.5 is not. Problem reported by Fedor
513 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
515 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
517 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
518 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
519 Warn about obsolete install-sh files. Remove stray sentence
520 fragment and fix cross reference.
521 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
522 install -d; this undoes the 2006-05-10 change.
523 (MKDIR_P): Mark with AN_MAKEVAR.
524 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
525 that we don't require $INSTALL to be thread-safe. Move comments
526 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
527 of AC_PROG_INSTALL. Output a message saying that we're checking
528 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
529 MKDIR_P instead of AC_SUBST.
530 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
531 Special magic for MKDIR_P, too.
532 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
534 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
536 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
538 Sync from Automake, as follows:
540 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
541 * config/install-sh: Initialize IFS, so field splitting isn't
543 * config/mkinstalldirs: Likewise.
544 * config/missing: Remove superfluous quotes. Replace all uses of
545 `[' by `test', for consistency, and for..
546 * config/missing (sed_minuso, sed_output): New variables.
547 (autom4te, help2man, makeinfo): Use them. Unifies detection of
548 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
549 Fixes `missing' to detect `--output' for help2man. Fixes
550 PR automake/483. Report by Dennis J. Linse.
551 (autom4te): Document in `missing --help'.
553 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
555 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
556 * config/install-sh: Don't use 'path' to talk about file names,
557 as per GNU coding standards. Close a race condition reported by Ralf
558 Wildenhues and Stepan Kasal. There is still a race condition
559 on hosts that predate Posix 1003.1-1992, but we can't help this.
560 Don't mishandle weird characters like space on pre-Posix hosts.
561 Invoke mkdir at most once per dir arg on pre-Posix hosts.
562 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
563 AC_PROG_MKDIR_P from AS_MKDIR_P.
564 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
565 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
566 earlier editions are not (including Automake 1.8.3).
567 Do not suggest mkinstalldirs for thread-safety.
568 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
569 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
570 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
571 presence of special characters and race conditions.
572 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
573 in Autoconf's name space.
575 2006-05-10 Bruno Haible <bruno@clisp.org>
576 and Paul Eggert <eggert@cs.ucla.edu>
578 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
579 from Automake with minor changes.

582 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
584 * config/install-sh: Update to Automake CVS version, as follows:
585 2006-04-25 Stepan Kasal <kasal@ucw.cz>
586 * lib/install-sh: Simplify the expr implementation of dirname.
587 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
588 * lib/install-sh: Handle --, and diagnose unknown options.
590 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
592 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
593 `./autom4te' to create `./testsuite', since the `all' target
594 will ensure its presence, but `installcheck' should not create
595 the uninstalled wrappers.
597 * tests/torture.at (Unusual Automake input files): Skip if we
598 detect automake < 1.8.
600 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
602 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
603 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
604 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
607 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
609 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
610 munge (multiple) white space and other oddities.
611 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
612 single quotes in variable assignment.
613 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
614 and similar failures by adding multiple spaces, tabs, and other
616 Report and different test suggested by Francesco Romani
617 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
619 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
620 single quotes, we only need to search for single quotes; this
621 both simplifies the search pattern, and makes us less
622 susceptible to `echo' variations for arguments not containing
624 (_AC_ARG_VAR_VALIDATE): Likewise.
626 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
628 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
629 `$*' and IFS concatenation issue with traditional shells and
630 bash-2.04. Report by Seanster@Seanster.com.
632 2006-05-03 Bruno Haible <bruno@clisp.org>
634 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
635 precisely which Mac OS X versions have the od problem.

639 * doc/autoconf.texi: Use @option systematically.
642 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
643 and Bruno Haible <bruno@clisp.org>
645 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
647 (Integer Overflow): Mention the special case of integer division
650 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
652 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
653 traditional shells like the Solaris one that do not use the
654 first IFS character for assembling `$*'.
655 Prompted by a related report from autoconf_bug@nro.ca.
657 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
658 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

669 in URLs to improve DVI formatted output (requires texinfo 4.6).
670 (System Services, Systemology, Shellology): Likewise.
671 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
674 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
676 (Runtime): Fix macro argument names to match description:
677 `action-if-found' -> `action-if-true' and similarly.
678 (Obsolete Macros): Likewise.
679 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
680 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
681 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
683 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
685 * doc/autoconf.texi (Limitations of Make): Clean up markup.
688 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
691 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
693 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
694 /bin/sh set unsorted output.
695 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
696 * tests/local.at: Likewise.
698 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
700 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
701 (Integer Overflow, Null Pointers, Buffer Overruns):
702 (Floating Point Portability, Exiting Portably): New sections.
703 (Writing Test Programs): Fix some langauge. Recommend exiting
704 with status 1, not merely nonzero. Clarify exit declaration.
705 (Run Time): Move C exit status stuff to new Exiting Portably section.
706 (Systemology): Mention Posix and levenez. Update v7 reference.
707 (Portable Shell): Mention the Posix shell.
709 2006-04-25 Stepan Kasal <kasal@ucw.cz>
711 * bin/autoconf.as (me): Replace by as_me.
713 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
715 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
716 since as_me isn't set yet.
718 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
720 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
721 a few minor bugs in this area.
723 * doc/autoconf.texi (Programming in M4sh): Comment out the
724 documentation of AS_BASENAME, for now.
725 (Shell Substitutions): Do not use AS_DIRNAME in an example.
726 (Limitations of Builtins) <basename>: Do not refer to
728 * bin/autoconf.as (me): Don't use AS_BASENAME.
729 (dir): Remove the unused variable.
730 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from

737 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
738 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
739 (_AS_DIRNAME_PREPARE): Likewise.

741 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
742 (AS_DIRNAME): Use "dirname --".
744 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
746 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
747 of "run time" and "run-time" changed to "runtime", for consistency.
748 * lib/autoconf/fortran.m4: Likewise (in comment).
749 * lib/autoconf/functions.m4: Likewise.
750 * lib/autoconf/general.m4: Likewise.
751 * lib/autoconf/headers.m4: Likewise.
753 * doc/autoconf.texi (Run Time): Document the exit status situation
754 with more accuracy and detail.
756 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
758 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
759 Archive is not officially `GNU' any more. Update URL.

761 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
763 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
765 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
766 newline from the `trap' code to finish `config.log'; the NetBSD
767 /bin/sh resets the exit status after an empty command, as
768 documented in doc/autoconf.texi.
769 Reported by Dalibor Topic <robilad@kaffe.org>.
771 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
773 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
774 Suggested by Bruno Haible.
776 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
778 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
779 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
780 Instead, just list the shells that we know work.
781 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
782 changed. Be more cautious about the _cv_ variable.
783 * tests/tools.at (Syntax of the shell scripts): Check the
784 _cv_ variable once, at first, to avoid an internal autoconf error
785 when sh -n does not work.
787 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
789 * lib/Autom4te/FileUtils.pm: Sync from Automake.
791 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
793 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
794 use ">&-" since we're only 99.999% sure that this is portable,
795 and since the MinGW bug is fixed in a different way.
796 * lib/autotest/general.m4 (AT_INIT): Likewise.
798 2006-04-16 Stepan Kasal <kasal@ucw.cz>
800 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
801 before opening config.log, to avoid hitting a bug on MinGW.
803 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
805 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
806 AS_MESSAGE_LOG_FD before reopening it onto the log file.
807 This works around a MinGW bug reported by Eric Paire.
808 Make sure that all writes to the log file append to it,
809 rather than possibly losing data.
810 * lib/autotest/general.m4 (AT_INIT): Likewise.
812 2006-04-14 Stepan Kasal <kasal@ucw.cz>
814 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
817 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
821 * configure.ac (AC_INIT): Bump to 2.59d.
823 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
827 * Makefile.maint (news-date-check): Do not require a leading `*'
828 before the release date in NEWS.
830 2006-04-12 Stepan Kasal <kasal@ucw.cz>
831 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
833 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
834 the instantiated file do not contain the string 'datarootdir'
835 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
836 @mandir@, replace the reference '${datarootdir}' by the value.
837 * tests/torture.at (datarootdir workaround): New test.
838 * NEWS: Advertise this temporary fixup.
839 Based on a patch by Bruno Haible, reported and analyzed by
840 Paul Eggert and Noah Misch.
842 2006-04-12 Eric Blake <ebb9@byu.net>
844 * tests/autotest.at (Debugging a failed test): Fix comment.
846 2006-04-12 Stepan Kasal <kasal@ucw.cz>
848 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
849 all the changes since 2006-04-07.
851 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
853 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
854 succeeded, but `ln -s file dir' failed, take care to remove the
855 leftover target before the next test, to prevent its spurious
856 failure; also make sure `ln file dir' works before selecting it.
857 Thanks to Keith Marshall for pointing this out.
860 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
861 assignments in `at_debug_args', so that we put them correctly
863 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
864 Reported by Eric Blake.
866 2006-04-11 Eric Blake <ebb9@byu.net>
868 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
869 top-level tests after micro-suite has been run. Used in...
870 (Debugging a successful test, Debugging script and environment),
871 (Debugging a failed test): ...these new tests. The first of these
873 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
874 macro, split out from...
875 (AT_INIT): ...here, so that using -d also generates a run script.
876 Document that -d inhibits top-level logging.
877 * doc/autoconf.texi (testsuite Invocation): Document that -d only
878 inhibits top-level logging; debug scripts are created.
880 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
882 * tests/autotest.at (Empty test, Empty check): New test to check it.
884 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
887 2006-04-10 Stepan Kasal <kasal@ucw.cz>
889 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
890 the files if a problem appears. Make the empty *.at files
891 read-only, too. Proposed by Ralf Wildenhues.
893 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
895 * config/Makefile.am: Add comment to force updated Makefile.in.
897 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
898 space only patch to this file, this patch causes the Makefile.in
899 files that include freeze.mk to be updated, and thus have a
900 newer time stamp again, which in turn makes a pristine CVS
901 checkout have correct time stamps.
903 * Makefile.maint (cvs-sv): New macro, to be used..
904 (config.guess-url_prefix, config.sub-url_prefix)
905 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
906 point to CVS text checkout of Gnulib files.
907 (copyright-check): Bump current year.
908 (announcement): Do not hard-wire `./announce-gen'.
909 (cvs-update): Propagate failures of `cvs' and `move-if-change'
911 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
913 (wget_files): Update config.guess, config.sub, texinfo.tex by
914 `wget-update', now that their URLs work again.
916 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
918 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
919 Problem noted by Paul D. Smith.
921 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
923 * doc/autoconf.texi: Remove unused words from word list.
924 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
925 .x-sc_trailing_space: New files.
927 * doc/standards.texi: Sync from gnulib.
929 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
930 `LIBOBJDIR' as experimental.
932 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
933 with a target directory; it's internally implemented as `cp'
934 anyway, but since Autoconf advertises the possibility to use
935 a target directory when LN_S is `ln -s', we need to find out.
936 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
937 analyzed by Keith Marshall <keith.marshall@total.com>.
941 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
943 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
944 confdefs.h as-is. In general, if it has backslash-newline or the
945 like, then it doesn't work either to sort or to remove empty
948 2006-04-09 Stepan Kasal <kasal@ucw.cz>
950 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
952 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
954 * lib/autom4te.in (Automake-preselections): Preselect

1052 _AS_DETECT_BETTER_SHELL:
1054 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not

1105 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1107 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1108 whether `set' quotes correctly: redirect stderr of the tested
1109 `set', and use a subshell, for Ultrix; use `sed' instead of
1110 `grep' for zsh `set' which may write binary output; match only
1111 at the beginning of a line, to avoid false positives.
1112 In order to avoid false positives by unrelated variables with
1113 multiline content, put the dump algorithm in a subshell and
1114 unset all variables containing newlines (except some which are
1115 special to the shell). Warn about cache variables that are

1164 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1165 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

2108 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2109 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2110 by the function rather than ignoring it.
2111 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2112 comparing its address. Intel's interprocedural optimization was
2113 outsmarting the old heuristic. Problem reported by

2131 Stepan Kasal <kasal@ucw.cz>
2133 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2134 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,

2137 to the main log file.
2139 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2141 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

2146 problems if the testsuite were running too fast.
2148 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2150 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2151 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2152 (which belong to Xt, not X itself). See Debian bug 327655.
2153 * NEWS: Mention this.
2155 2005-09-07 Stepan Kasal <kasal@ucw.cz>

2162 suggested by Ben Elliston. Handle weird characters correctly.
2164 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2166 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2167 calls, so that the final expansion of this macro is shorter.
2168 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2169 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2170 the cleanup there. Use AS_VAR_* macros, to be more general.
2171 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2173 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2175 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

2193 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2195 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2196 in the example. Reported by Bruno Haible.
2197 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2198 "if $undefined_var;" succeeds with my shell.
2200 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2201 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2202 but change the m4_divert_text to m4_divert_once.
2204 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2206 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2207 Work around bug in Solaris /usr/xpg4/bin/awk.
2208 The bug is present in at least Solaris 8 through 10.
2210 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2212 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2213 some evil values and relying on the fact that $* concatenates the
2214 parameters by the first character from IFS.
2216 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2217 Stepan Kasal <kasal@ucw.cz>

2220 first header appears, define AH_HEADER.
2221 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2222 Update limitations about when to call AC_CONFIG_HEADERS.
2223 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2224 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2225 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2226 ``Configuration Actions''; fix their index entries.
2228 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2229 options correctly. Process N-M as M-N if M is smaller than N.
2230 Process ranges correctly so that N-N will run only N.
2231 Sort and uniquify the tests that will be run. If there is more
2232 than one test, reinsert the banners for the tests.
2233 * tests/autotest.at (Keywords): Unmark XFAIL.
2235 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2237 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2238 before passing the macro name to AH_TEMPLATE.
2240 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2241 now opens log after option processing; in particular, --version
2242 and --help do not touch config.log.
2244 * Makefile.maint: Revert the change from 2005-08-12.
2246 2005-08-22 Stepan Kasal <kasal@ucw.cz>

2255 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2258 * doc/autoconf.texi (Defining Symbols, Changed Results):
2259 Prepend to LIBS, not append, in examples.
2261 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2263 When building in place, set srcdir="."; suggested by Tim Van Holder.
2265 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2266 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2267 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2268 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2269 does not mean "no --srcdir option".
2271 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2273 * tests/autoscan.at (autoscan): New file.
2274 * tests/suite.at: Use it.

2276 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2278 * tests/autotest.at (Keywords): Test keywords combinations.
2280 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2282 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2283 add "2>&1"; gzip 1.2.4 prints help on stderr.
2285 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2287 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2288 was pushdef'ed twice while popped only once. Push it only once.
2289 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2291 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2293 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

2300 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2301 "<tab>" in comment, so that the point is understandable.
2303 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2305 Rewrite substantial part of lib/autoconf/status.m4.
2306 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2307 and CONFIG_COMMANDS are not processed in four separate loops.
2308 Instead, there is one main loop. This alows that the common code
2309 is expanded only once, thus config.status (and configure) is smaller.
2311 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2312 the AC_LIST_FILES and cousins macros are no longer used.
2314 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2315 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2316 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2317 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2318 contain the initialization, nor the for loop, nor the associated
2319 commands; all these go to ...
2320 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2321 _AC_OUTPUT_CONFIG_STATUS.
2322 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2323 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2324 (_AC_OUTPUT_FILE): The creation of the sed script ...
2325 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2326 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2327 _AC_OUTPUT_MAIN_LOOP.
2328 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2329 _AC_CONFIG_COMMANDS): Use ...
2330 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2331 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2332 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2333 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2334 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2335 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2337 (_AC_CONFIG_UNIQUE): Update.
2338 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2339 Replaced by this ...
2340 (_AC_LIST_TAGS): ... new common macro.
2341 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2342 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2343 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2344 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2345 this didn't belong to the `config commands' section.
2346 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2347 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2348 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2349 to the `config commands' section either.
2350 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2351 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.

2365 parameter to AC_DIAGNOSE.
2366 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2367 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2368 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2369 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2371 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code

2405 for loop, instead of expanding all commands, or, OTOH, complicated
2406 processing of output of "set".
2407 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the

2464 sed substitution command, so that we allow | in program prefixes
2465 and program suffixes. (& is a problem anyway; we're not fixing
2467 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2468 configure_input, top_builddir, srcdir, etc.
2469 * lib/autotest/general.m4 (AT_INIT): Likewise, for

2480 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

2533 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2534 the directory specific variables; but don't call it for configure_input.

2538 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2541 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

2561 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
2562 variable into diagnostic. Make the diagnostic an error, not a warning,
2563 because we really don't support spaces and suchlike in dir names.
2564 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2565 Don't worry about backslashes in srcdir; it can't happen now.

2594 (Special Shell Variables): Fix sed code this in the example.
2595 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.

2609 * doc/autoconf.texi:
2610 Don't mention Solaris versions so much, if a
2611 problem is common to all extant versions of Solaris. Say "SunOS
2612 4" instead of "SunOS" for SunOS 4.
2613 (awk): Mention more of the limitations of traditional Awk.

2656 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2657 -u, since it outputs chatter if the input files are the same.
2658 Problem reported by Ralf Menzel.
2660 2005-06-08 Derek Price <derek@ximbiot.com>
2662 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2663 renaming them since they are about to be redefined anyhow.
2665 2005-06-08 Derek Price <derek@ximbiot.com>
2667 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2668 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2669 Move m4_undefine to alphabetical order.

2674 * doc/autoconf.texi (Introduction): Likewise.
2675 Reword to avoid some formatting glitches.

2680 might get inadvertently cut-and-pasted into user code.
2681 Remove example of autom4te usage that doesn't seem to work now.

2702 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2704 m4_cdr of one-member list was [[]] (one-member list containing an
2705 empty string) instead of [] (an empty list. Callers were skewed to
2706 match this misbehaviour. As a consequence of this:
2707 - m4_foreach([x], [], [foo]) expanded to `foo', while
2708 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2709 This bug has been fixed:
2711 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2712 expand to an empty string; print error msg if called without
2714 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2715 misbehaviour; handle [] and [[]] correctly.

2725 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2726 swallow records with more than 99 fields.
2727 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2728 parse the long line.
2730 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2732 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2733 swallow literals longer than 399. Reported by Ralf Wildenhues.

2767 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2768 now contain newlines, and substituted files must be referenced on
2769 a line alone; the sed scripts to substitute them are now very

2772 commands can be put in a sed script portably.

2817 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
2819 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2821 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
2822 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
2823 (ac_top_builddir): ... this ...
2824 (ac_top_build_prefix): ... to this; the old name is also kept, for
2825 backward compatibility.
2826 (ac_top_builddir_sub): New variable, without the trailing slash,
2828 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
2829 * doc/autoconf.texi (Configuration Actions): Rename
2830 ac_top_builddir to ac_top_build_prefix.
2831 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
2832 at_top_builddir to at_top_build_prefix.

2837 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
2840 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2842 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2843 argument to m4_foreach. I guess it was necessary in the past,
2844 but I think it's a no-op now.
2846 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2848 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2849 ``cat <<_ACEOF'' commands to one.
2850 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
2851 * lib/autoconf/status.m4: On various places, use expr instead of
2853 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
2854 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2855 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2857 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2858 the wrong patterns between ``case'' and ``esac.'' The previous
2859 code had false positives.

2918 2005-05-11 Stepan Kasal <kasal@ucw.cz>
2920 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
2921 for absolute directory names in one loop.

2923 abbreviations of --version and --debug.
2925 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
2927 * doc/autoconf.texi (Autoconf Language): Be more precise about
2928 quoting rules. Problems noted by Stepan Kasal.
2929 Also, throughout this document, be more careful about white space.
2930 "blank", "white space", and "space" all have different meanings
2931 and we should be careful to say what we mean.
2933 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
2935 Fix C++ related problems reported by Werner Lemberg.
2936 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
2937 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
2938 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
2939 avoid problems with C++ and throw.
2940 * tests/compile.at: .cpp, not .cc.
2942 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
2944 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2946 * doc/autoconf.texi (Generic Functions): Typos.
2948 2005-05-02 Gary V. Vaughan <gary@gnu.org>
2950 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
2951 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
2952 set by latest automake.
2954 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2956 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
2957 outputs 0 on GNU/Linux these days.
2959 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
2961 * doc/autoconf.texi (Autoconf Language): Add more description
2962 about quoting heuristics.
2963 (Limitations of Builtins): Describe "set -" problems.
2965 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2967 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
2970 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
2971 by AC_DEFINE; it was a mistake.
2972 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
2974 2005-04-25 Stepan Kasal <kasal@ucw.cz>
2976 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
2978 2005-04-22 Stepan Kasal <kasal@ucw.cz>
2980 * doc/autoconf.texi (External Software): Quadrigraphs are not
2981 processed correctly in AS_HELP_STRING; avoid this in the examples.
2982 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
2983 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
2984 comment and reduce m4_default([foo], []) to [foo].
2985 (m4_strip): Update the explanation.
2987 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
2989 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
2990 Remove core.conftest.* too; it's generated by Tru64 5.1.
2991 Problem reported by Jennis Pruett.
2992 * lib/autoconf/functions.m4
2993 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2994 Don't bother to remove core files; AC_RUN_IFELSE should do that
2997 2005-04-19 Stepan Kasal <kasal@ucw.cz>
2999 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

3003 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
3004 Report from Horst Wente.
3006 2005-04-15 Stepan Kasal <kasal@ucw.cz>

3013 * doc/autoconf.texi (External Software, Package Options): Add
3014 examples showing how to implement --with-* and --enable-* options.
3016 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3018 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3019 as well as configure.in. Problem reported by Gregorio Guidi.
3021 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3023 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3024 pattern for alloca snippet.

3034 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3036 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3037 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3039 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3041 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3042 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3043 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3044 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3045 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3047 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3049 * NEWS: The configure command now warns you if you attempt to use
3050 a directory whose name contains a special character like space,
3052 * doc/autoconf.texi (Installation Directory Variables): Allow
3053 "," in file names. Do not use \@; it's not a portable regexp.
3054 * bin/Makefile.am (edit): Likewise.
3055 * lib/Makefile.am (edit): Likewise.
3056 * tests/Makefile.am (edit): Likewise.
3057 * tests/semantics.at: Likewise.
3058 * tests/torture.at: Likewise.
3059 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3060 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3061 * doc/autoconf.texi (File System Conventions): Warn about
3062 unportable file names.
3063 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3065 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3066 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3067 ac_pwd, and quote srcdir.
3068 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3070 * doc/autoconf.texi: Fix some systematic formatting problems.
3071 ".)" needs a following @: if not at the end of a sentence, and
3072 similarly for "!)". "etc." should be preceded by a comma.
3073 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3075 2005-03-22 Bruno Haible <bruno@clisp.org>
3077 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3078 argument is often called 'build-aux'.
3080 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3082 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3083 macro AC_TRY_LINK is obsolete.
3084 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3087 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3089 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3090 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3091 from a Common Lisp's `cl'.
3092 (AC_PROG_CXX): Behave according to the documentation: don't
3093 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3094 make the variable CCC precious; use `cl.exe', not `cl'.
3096 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3097 Alexandre Duret-Lutz <adl@gnu.org>
3099 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3100 /dev/null, as "configure" shouldn't read stdin, and this insulates
3101 us from problems (e.g., when testing for "cl"). Also, do this
3102 redirection before invoking "hostname" or "uname", and keep the
3103 original input stream available via...
3104 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3105 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3106 bother with "</dev/null" since it's now done at the top of
3108 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3109 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3110 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3111 * doc/autoconf.texi (File Descriptor Macros): New section.
3112 (Printing Messages): Mention it.
3113 * tests/base.at (Input/Output): New test.
3115 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3117 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3118 newline if neither \c nor -n work, as that would output two
3119 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3121 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3123 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3124 This causes that any required macros inside will get before the if.
3125 * doc/autoconf.texi (autom4te.cache): A typo.
3127 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3129 Undo previous change, except keep the change to
3130 lib/autoconf/programs.m4 that replaced grep with shell
3131 pattern-matching. This is because net-snmp configure reads stdin.
3132 Reported by Noah Misch.
3134 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3136 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3137 from /dev/null, as "configure" shouldn't read stdin, and this
3138 insulates us from problems (e.g., when testing for "cl").
3139 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3140 before invoking "hostname" or "uname".
3141 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3142 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3143 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3144 "</dev/null" since it's now done at the top of 'configure'.
3145 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3146 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3147 Also, replace grep with shell pattern-matching, to save a process.
3149 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3151 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3152 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3153 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3156 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3158 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3159 grep -q isn't portable. Improve grep -s explanation.
3160 Problem reported by Dan Manthey.
3162 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3164 * doc/autoconf.texi (Special Shell Variables): Clarify
3165 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3167 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3169 * doc/autoconf.texi: Use @acronym for DJGPP.
3170 Fix some @code's that should have been @env's, and vice versa.
3171 Sort environment variable names.
3172 Mention that shells no longer inherit IFS.
3173 Don't recommend PATH_SEPARATOR=';' so strongly.
3174 Mention that $RANDOM might expand to the empty string.
3175 "symlink" and "soft link" -> "symbolic link".
3176 Improve mktemp description (reported by Bruno Haible).
3178 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3180 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3181 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3183 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3186 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3188 * NEWS: Mention AT_COPYRIGHT.
3190 * tests/local.at (AT_CMP): Use diff directly on input files rather
3193 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3194 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3196 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3197 and Paul Eggert <eggert@cs.ucla.edu>
3199 * tests/autotest.at (Empty test suite): New test.
3200 * tests/torture.at (Substitute and define special characters)
3201 (Substitute a 2000-byte string, Define to a 2000-byte string)
3202 (Substitute a newline, Define a newline): New tests.
3204 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3206 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3207 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3208 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3209 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3210 (Standard regular expressions): New test.
3211 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3212 excess test name quoting.
3213 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3214 CPPFLAGS to `configure' instead of setting it in `configure'.
3216 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3217 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3220 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3221 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
3223 * tests/local.at (AT_CMP): New macro.
3224 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
3225 (AC_SAVE_STATE): Move environment grep...
3226 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
3227 (AT_CONFIG_CMP): New macro.
3228 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
3229 * tests/c.at (Extensions): Do not exit early.
3230 * tests/atlocal.in: Inherit $GREP.
3232 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
3233 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
3235 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
3236 (AC_COPYRIGHT): Factor header comment portion out and move into...
3237 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
3238 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
3239 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
3241 * tests/local.at: Add Autoconf test suite copyright notice.
3242 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.

3249 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3251 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3252 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3254 Try not to generated lines of unlimited length, as POSIX places a
3255 2047-byte limit on line length of portable text files.
3256 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3257 Use newline as a separator, not space.

3315 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3316 Update the long comment explaining it.
3318 m4_require no longer writes an ``is required by'' line to the
3319 execution stack. It contains only one bit of non-redundant
3320 information: that the macro was required, not called. And even
3321 this bit is useless in most situations: have you ever met a macro
3322 which both calls and requires the same macro?
3324 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3325 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3333 * tests/m4sugar.at (m4_require): Expect output without the
3334 ``is required by'' messages.
3336 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

3372 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3373 Warn about newline stripping in `` and $(). Update Solaris
3375 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3376 X insulates us from future changes to Posix.
3377 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

3402 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3404 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3430 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3431 stored in _m4_divert_diversion or _m4_divert_dump.
3432 (m4_divert_pop): When the parameter is given, compare the symbolic
3433 name with the last diversion pushed on the stack. Previously, the
3434 current diversion was compared with the numeric value of the
3435 diversion given as the parameter.
3436 (m4_require): If the macro hasn't been expanded yet, call ...
3437 (_m4_require_call): this new macro.

3470 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

3736 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
3737 out the common code to ...
3738 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
3739 value of the #define--default to 1, iff the macro was called
3740 with exactly one parameter.
3742 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
3744 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
3745 "char c = '\200';" rather than "char c = 0x80;" as the
3746 latter doesn't conform to the strict C standard due to
3747 overflow on signed char hosts.
3749 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
3750 to -qlanglvl=ansi. We don't want to disable extensions.
3752 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
3754 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
3755 (Using Autotest, testsuite Scripts, Writing testsuite.at):

3807 simplify the examples and improve their quoting.
3809 2004-11-13 Stepan Kasal <kasal@ucw.cz>
3811 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
3812 the $1_found variable, don't test whether the file is executable;
3813 Both things are checked ...
3814 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
3815 the former ``test -f''.

3826 limitations. Reorder paragraphs for clarity.
3828 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
3830 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
3831 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
3832 variants", "Unix", and some related minor wording fixups.
3834 (Shellology, Special Shell Variables): Document that the Zsh
3835 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
3836 to Alexandre Duret-Lutz for this info.

3847 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
3849 * doc/autoconf.texi (auindex): New macro.
3850 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
3851 Problem reported by Stepan Kasal.
3853 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
3855 Fix problems reported by Andreas Buening in:
3856 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
3857 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
3859 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
3860 readable; it's not true in OS/2-emx.
3862 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
3864 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
3865 "/usr/include", clear ac_x_includes instead of leaving it as "no"
3866 (trivial change). Problem and patch reported by Andrew Church in:
3867 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html

3896 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
3897 texinfo.tex for now (done by hand now).
3898 * Makefile.maint (wget_files, cvs_files):
3899 Remove ansi2knr.c; nobody uses it.
3900 (ansi2knr.c-url_prefix): Remove.
3901 (cvs-update): Fix test for failure. I don't know why it ever
3904 * doc/autoconf.texi: Update URLs, some of which went stale.
3905 Use @uref rather than @href.
3907 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
3908 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
3910 * config/config.guess, config/config.sub, config/elisp-comp,
3911 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
3912 doc/fdl.texi, doc/standards.texi: Sync with master copy.

3922 Use "file name" rather than "filename" or "path",
3923 to be consistent with the terminology of the GNU coding standards.
3925 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
3927 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
3928 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
3929 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
3930 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
3932 More fixes to support spaces in the name of the build directory.
3933 This isn't a complete fix but it's an improvement.
3935 * bin/autoconf.as (autom4te_options): New var.
3936 Use it instead of appending to AUTOM4TE, so that we can allow
3937 spaces in the build directory's absolute name.
3938 * bin/autoheader.in ($autoconf): Allow spaces in file names.
3939 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
3940 AT_CHECK_NOESCAPE): Likewise.
3941 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
3942 main program): Likewise.
3944 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
3946 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

3953 and isnan. From a suggestion by Kevin Ryde.
3955 * lib/Autom4te/General.pm (END): Return correct exit status even
3956 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
3958 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
3960 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
3961 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
3962 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
3964 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
3966 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
3967 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
3968 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
3969 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
3970 * lib/autom4te.in (Automake-preselections): Preselect
3971 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
3973 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
3975 * lib/autom4te.in (Automake-preselections): Preselect
3976 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
3979 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>

3984 Document problem with "`""`" in pdksh POSIX mode.
3986 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
3988 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
3989 with pdksh, too. Problem reported by Patrick Welche via
3991 * doc/autoconf.texi (Shellology): Note that set -o posix is
3992 useful for pkdsh, too.
3994 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
3996 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
3997 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
3998 Don't fail if ENV or BASH_ENV is readonly.
3999 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4000 etc. are read only. Problem reported by Ludovic Courtes.
4002 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4004 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4005 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4008 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4010 * doc/autoconf.texi (File System Conventions): Warn about
4011 names like "aux". Problem reported by Eric Blake.
4013 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4014 by zero instead of array size, so that we can use any arithmetic
4015 constant expression (instead of requiring an integer constant
4016 expression). This allows us to test expressions like DBL_MAX <
4017 LDBL_MAX, which didn't conform to the C standard using the old
4019 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4020 now that we can do floating-point tests at compile time.
4022 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4024 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4025 and LDBL_EPSILON, as the resulting expression isn't an
4026 integer constant expression and violates the C standard.
4027 Problem reported by Nelson H. F. Beebe. Also, check
4028 for "L" suffix, and check that long double doesn't have
4029 worse range or precision than double, that mixed-mode
4030 arithmetic doesn't generate a diagnostic, that double
4031 constants fit in long double.
4033 2004-06-03 Kevin Ryde <user42@zip.com.au>
4035 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4036 malloc(0) and realloc(NULL,size).
4038 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4041 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4043 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4044 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4047 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4049 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4050 can be rewritten using if-then-else. Suggested by Bruno Haible.
4052 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4054 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4055 Problem reported by Stepan Kasal.
4057 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4059 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4060 change). Patch reported by Ralf Wildenhues in
4061 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4063 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4064 function F exists if the compiler and linker let you compile an
4065 expression like (F != 0). Recent versions of GCC optimize away
4066 the reference to F in that case, since every function address must
4067 be nonzero, so the link succeeds even if F does not exist.
4068 Problem reported by Manu in
4069 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4071 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4072 "Unix". Many uses changed.
4073 (Limitations of Builtins): Explain better why the ! command isn't
4076 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>

4079 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4081 2004-05-19 Kevin Ryde <user42@zip.com.au>
4083 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4084 referencing AC_FUNC_STRERROR_R.
4086 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4087 note pessimistic assumption when cross compiling.
4089 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4091 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4092 (until 2004) invoked subcommands with sh -e, contra POSIX.
4093 Reported by Kevin Ryde.
4095 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4097 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4098 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4099 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4100 `test -f " /usr/bin/grep"', which _always_ failed.
4101 (AC_PROG_SED): Ditto bogus PATH fix.
4102 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4103 requires that grep correctly supports _multiple_ `-e' options, rather
4104 than stating only that grep should accept `-e'.
4106 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4108 Port to C99, which requires that 'exit' be declared.
4110 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4111 to ensure that stdlib.h is included.
4112 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4113 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4114 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4115 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4116 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4117 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4118 when using 'exit' in a test; C99 requires that 'exit' be declared.
4120 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4122 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4123 now prefers 'grep' implementations that accept -e.
4124 (Limitations of Usual Tools): Describe problems of traditional
4125 egrep and fgrep with long input lines, and of traditional grep
4127 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4128 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4129 All callers changed. Append /usr/xpg4/bin to the PATH, for
4131 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4132 the user with complaints about multiple -e options.
4133 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4134 Define it with AC_PROG_GREP.
4135 * configure.ac (AC_PROG_GREP): Add.
4136 * lib/freeze.mk (GREP): New macro.
4138 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4140 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4141 a possible candidate only after all others fail, rather than
4142 consulting it first. This improves backward compatibility by
4143 better reflecting the way shell selection occurred in previous
4144 versions of Autoconf, and should help to avoid triggering latent
4145 problems in other packages, such as the one in Automake where zsh
4146 is not handled robustly:
4147 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4148 Although it is not Autoconf's responsibility to work around
4149 problems in Automake, it nevertheless makes sense to avoid
4150 introducing unnecessary incompatibilites.
4152 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4153 Gary V. Vaughan <gary@gnu.org>
4155 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4156 how deeply nested we are when a suitable tool is found, set the
4157 ac_path_TOOL_found flag.
4158 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4159 nested we are in this macro. Break out of all 3 nested loops if
4160 ac_path_TOOL_found is set.
4162 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4164 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4165 of the _AS_PATH_WALK loop too if GNU flavor is found.
4167 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4169 * doc/autoconf.texi (Limitations of Make): Update documentation
4170 for `$<'. New entry `Long lines', based on a report from Simon
4171 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4172 paragraph about DJGPP, based on a mail from Richard Dawe.
4174 2004-04-20 Paul Eggert <eggert@twinsun.com>
4176 * tests/c.at (C keywords): Don't assume that GCC supports
4177 "restrict" and "inline", as sufficiently-old GCC versions do not
4178 (also, GCC configured to be in pedantic C89 mode does not).
4179 Problem reported by Sumit Pandya in:
4180 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4182 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4183 consider -g to work if it generates warnings when plain compiles

4311 Problem reported by Anthony N. Frasso in
4312 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

4341 AC_SUBST provides no portable way to escape literal newlines.
4343 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4344 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4345 Darwin uses -lcrt2.o and there's little point to cataloging all
4346 the system variants. Partial fix reported by Andreas Waechter in:

4374 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

4422 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4423 2003 (except 1997) to the list of copyright years. This undoes
4424 the 2003-05-22 change, which removed the older years from the list.
4425 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

4471 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4472 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4473 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4474 not <inttypes.h>. Problem reported by Tim Mooney in

4476 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4479 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4480 otherwise "make check" fails because it forbids cmp (I guess
4481 because cmp treats files as binary on DOS-like systems).

4484 have changed in 2004.

4496 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4497 -std1 disables some useful extensions on Tru64. Problem reported

4503 * doc/autoconf.texi (Programming in M4sh): Document that
4504 AS_MKDIR_P succeeds if the destination is a symbolic link
4505 to an existing directory.
4506 (Limitations of Usual Tools): Note that mkdir -p might not
4507 succeed on symlinks to directories.

4528 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4529 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4530 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4531 AC_COMPILE_IFELSE, since we now assume our caller invokes
4532 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4533 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4534 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4535 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4537 2004-01-07 Paul Eggert <eggert@twinsun.com>
4539 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4540 `"'...'"`, as it's confusing (and I suspect it may not work on
4541 some platforms). The code was incorrect anyway, as it assumed
4542 that \$ evaluated to itself in that context. Reported by
4543 Alexandre Duret-Lutz.
4545 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

4577 Bug reported by David Relson in
4578 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4580 * Makefile.am (autom4te-update):

4597 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4598 -c -o might not work. From a suggestion by Kevin Ryde.
4599 (C Compiler, Generating Sources, Limitations
4600 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4601 Don't put '-o' after non-options, as POSIX doesn't allow this.
4602 Mention that cc's name might be gcc or c89 or whatever.

4613 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4615 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4616 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
4617 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
4618 explanation clearer.

4628 * configure: Regenerate.
4629 * tests/atlocal.in: Store the result here.
4630 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
4631 tools.at, looking in atlocal's ac_cv_sh_n_works instead
4632 of explicitly testing.
4633 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
4634 (AT_CHECK_AUTOCONF): Test for the configure script syntax.

4901 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
4903 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
4904 -mGLOB_options_string stuff for Intel ifc, which can cause
4905 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

4928 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
4929 cache variable instead of $G77 to decide whether to include -O2,
4930 since $G77 is specific to Fortran 77.
4932 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4934 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
4935 free" flag. Re-order flags tested into rough order of popularity.
4937 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4939 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
4940 arguments so that it can be used with syntax identical to

5016 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5017 directory for AC_CONFIG_COMMANDS' first argument exists.
5018 This makes valid the invocation of _AC_SRCPATH that follows.

5043 The test suite are sometimes assigning timings incorrectly.
5044 Reported by Henk Krus.
5045 Diagnosed by Nicolas Joly.
5047 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5049 Instead of making AT_help a sequence of assignments to grow

5053 (at_times_skip): Flip the meaning and rename as...

5065 (ifnames): chmod -w.
5066 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5067 executables, not bin/ executables! Otherwise all the magic needed
5068 to find non installed files is turned off. This caused a failure
5069 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5070 as found in its environment (sent by tests/autoreconf): pointing
5071 to bin/autom4te that could not find its files.
5072 * tests/mktests.sh: Force the replacement of generated files, for
5073 the sake of "mv" program that are interactive when overwriting a

5166 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5168 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5170 Add support for newer Fortran dialects. The F77 interface is
5171 unchanged, and continues to support Fortran 77. New FC macros
5172 correspond to all the old F77 macros, with output variables FC,
5173 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5174 available dialect, but older dialects can be specified. There are
5175 new macros AC_FC_SRCEXT to set the source extension, and
5176 AC_FC_FREEFORM to accept free-form source files.
5178 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5180 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
5181 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

5191 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
5192 AC_FC_SRCEXT, AC_FC_FREEFORM):
5194 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
5195 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
5196 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5197 Rewrite in terms of the above.
5198 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5199 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
5200 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
5201 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
5203 2003-09-02 Paul Eggert <eggert@twinsun.com>
5205 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5206 Document problems with timestamp resolution that 'make', 'cp -p', and
5209 2003-08-27 Akim Demaille <akim@epita.fr>
5211 * tests/m4sugar.at (cross_warning): Make sure to enable the
5212 output, so that we can track spurious m4sugar output.
5213 * tests/local.at: Require 2.57.
5214 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5215 are defaulted by AT_CHECK anyway.
5216 Use AT_CHECK_AUTOM4TE.
5217 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5220 2003-08-27 Akim Demaille <akim@epita.fr>
5222 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5223 when -Wobsolete is set.
5224 Set it on by default.
5225 Suggested by Klee Dienes.
5227 2003-08-27 Akim Demaille <akim@epita.fr>

5243 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
5245 * bin/autoreconf.in (parse_args): Do not pass --no-force to
5246 Automake versions prior to 1.8.
5248 2003-08-25 Akim Demaille <akim@epita.fr>
5250 * doc/autoconf.texi (Header Portability): netinet/if_ether.h.
5253 2003-08-24 Akim Demaille <akim@epita.fr>

5261 * Makefile.cfg (local-checks-to-skip): New.
5262 * Makefile.maint (local-check): Rename as...
5263 (local-checks-available): this.
5266 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
5267 * configure.ac: Require Automake 1.7.6.
5269 2003-08-22 Akim Demaille <akim@epita.fr>
5271 Output stack traces in warnings.
5273 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
5274 Replace the former...
5275 (m4_warn): Pass the call stack to _m4_warn.
5276 * bin/autom4te.in: Adjust to output the call stack.
5277 * tests/m4sugar.at (m4@&t@_warn): Adjust.
5279 2003-08-22 Akim Demaille <akim@epita.fr>
5281 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
5282 * bin/autom4te.in: Adjust.
5284 2003-08-21 Akim Demaille <akim@epita.fr>
5286 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
5288 (&getopt): Adjust the note and verb channels, depending upon
5290 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
5291 * bin/autoupdate.in: Adjust.
5292 Use &verb, not &verbose.
5294 2003-08-21 Akim Demaille <akim@epita.fr>
5296 * bin/autoheader.in (&parse_args): Use &parse_warnings and
5298 ($help): Use Autom4te::ChannelDefs::usage.
5299 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5300 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5302 2003-08-21 Akim Demaille <akim@epita.fr>
5304 First stab at preserving warnings between calls to autom4te,
5305 including when the cache is used.
5307 There are still several issues: (i) there are too many runs of m4
5308 (one for include, one for warnings, and some more), (ii) warnings
5309 spreading on several lines are not handled gracefully, (iii) the
5310 code meant to have the call stack display for errors does not work
5311 (its handling should move from m4 to autom4te).
5313 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5315 (@preselect): Add m4_warn.
5316 ($exit_status): Remove, use $exit_code.
5317 ($help): Use Autom4te::ChannelDefs::usage.
5318 (&handle_m4): No longer define the m4_warnings.
5319 At each run, extract and report the warnings.
5320 Always cache the result, including if the exit status is on
5321 failure, since if nothing changes, we should result in the same
5322 failure, hence we can use the cache.
5323 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5324 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5326 (m4_warn): Redefine as a do-nothing: it is its invocation that
5327 matters, as warnings are now reported via traces.
5328 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5329 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5330 the latter reveals calls to the former.
5334 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5336 2003-08-21 Akim Demaille <akim@epita.fr>
5338 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5341 2003-08-21 Akim Demaille <akim@epita.fr>
5343 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5345 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5346 (&parse_warnings): Accept a list of warning requests.
5347 (&usage): Return a string, not a side effect.
5348 (cross): New warning category.
5350 2003-08-21 Akim Demaille <akim@epita.fr>
5352 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5353 (&require_configure_ac): Accept an optional directory argument.
5354 ($configure_ac): Remove.
5355 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5357 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5358 * bin/autoscan.in: Adjust.
5360 2003-08-20 Akim Demaille <akim@epita.fr>
5362 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5363 Reported by Alexandre Duret-Lutz.
5365 2003-08-20 Akim Demaille <akim@epita.fr>
5367 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5368 * bin/autom4te: Adjust.
5369 In particular, be Autoconf tools are really silent when properly
5370 working, bind the verbosity of the 'note' channel to $verbose.
5371 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5372 (&xsystem, &contents): Remove, since they are exported by...
5373 * lib/Autom4te/FileUtils.pm: this.
5375 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5376 * lib/Autom4te/FileUtils.pm: here.
5378 2003-08-20 Akim Demaille <akim@epita.fr>
5380 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5381 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
5384 2003-08-20 Akim Demaille <akim@epita.fr>
5386 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
5387 (autom4te-update): New.
5388 * Makefile.cfg (update): Bind autom4te-update.
5390 2003-08-19 Derek Price <derek@ximbiot.com>
5392 * lib/autotest/general.m4: Comment various HELP_* diversions.

5396 package specific options and associated help.
5398 2003-08-19 Akim Demaille <akim@epita.fr>
5400 * config/announce-gen, Makefile.cfg: New.
5401 * Makefile.am: Adjust.
5402 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
5404 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5406 * lib/autom4te.in (Automake-preselections): Preselect
5407 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
5410 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5412 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
5413 (Autoconf-without-aclocal-m4): ... this new language.
5414 * doc/autoconf.texi (autom4te Invocation): Mention
5415 Autoconf-without-aclocal-m4.
5417 2003-08-18 Derek Price <derek@ximbiot.com>
5419 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
5420 RUN-IF-PASS optional arguments.

5426 2003-08-16 Derek Price <derek@ximbiot.com>
5428 * doc/autoconf.texi (Writing testsuite.at): Document defaults for
5429 STDOUT & STDERR arguments.
5431 2003-08-14 Derek Price <derek@ximbiot.com>
5433 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5434 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5435 shorter column three. Add DESCRIPTION to log file content.
5437 2003-08-13 Derek Price <derek@ximbiot.com>
5439 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
5442 2003-08-12 Derek Price <derek@ximbiot.com>
5444 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
5445 (AT_CHECK_NOESCAPE): Move core functionality to...
5446 (_AT_CHECK): ...this new macro.
5448 2003-08-07 Derek Price <derek@ximbiot.com>
5450 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
5451 (AT_CHECK_NOESCAPE): ...to this new macro.
5453 2003-07-31 Paul Eggert <eggert@twinsun.com>
5455 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5456 in Bash 2.01. Problem reported by Brian Gough in
5457 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
5459 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
5461 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
5462 -lcrt1.o, for OS X. (trivial change)
5464 2003-07-07 Paul Eggert <eggert@twinsun.com>
5466 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
5467 inside '#ifndef __cplusplus'. Problem reported by
5470 2003-07-06 Bill Clarke <llib@computer.org>
5472 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5473 'long', not 'int', for benefit of Sun's recent C++ compilers
5474 (trivial change). See:
5475 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

5481 * lib/Makefile.am (autom4te.cfg): Make it read only.
5482 Depend on Makefile since it contains substitutions.
5484 * lib/autom4te.in (args): Add local.at? for Autotest args.
5485 This change was made on autom4te.cfg which is generated.
5486 Reported by Raja R. Harinath.
5488 2003-06-25 Akim Demaille <akim@epita.fr>
5490 * doc/autoconf.texi (Header Portability): sys/mount.h.
5491 From Gareth McCaughan.
5493 2003-06-23 Akim Demaille <akim@epita.fr>
5495 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5496 not all of them. This fixes 1. the fact that when testing
5497 Autoconf there are many many config.log, 2. the incorrect use of
5498 top_srcdir to find config.log.
5499 Don't mix the detailed output of failed test with the summary of
5500 failures. Rather, append detailed log afterwards.
5502 2003-06-23 Akim Demaille <akim@epita.fr>
5504 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5505 always run: output config.log on $at_group_log.
5507 2003-06-23 Akim Demaille <akim@epita.fr>
5509 * tests/torture.at (#define header templates): Don't use quotes in
5510 C++ comments as it puzzles Emacs' sh font-lock-mode.
5512 2003-06-23 Akim Demaille <akim@epita.fr>
5514 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5515 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5516 * tests/atspecific.m4: Rename as...
5517 * tests/local.at: This.

5519 * tests/local.at: here.
5520 * tests/Makefile.am: Adjust.
5521 * doc/autoconf.texi (testsuite Scripts): Adjust.
5523 2003-06-21 Kevin Ryde <user42@zip.com.au>
5525 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5526 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5527 ensuring we add -std1 for full-ANSI.
5529 * doc/autoconf.texi (hdrindex): New macro.
5530 Add index entries for portability of various standard header files.
5532 2003-06-20 Akim Demaille <akim@epita.fr>
5534 * configure.ac: Bump to 2.57b.

5554 Update from masters.
5556 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
5558 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
5559 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5560 (TEST_SCRIPT): New diversion.
5561 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5562 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5563 (AT_INIT): Support for expected failures.
5565 2003-06-02 Akim Demaille <akim@epita.fr>
5567 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
5569 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5570 Autoconf nor Automake.
5571 (&contents): New, from Automake.
5574 2003-05-28 Paul Eggert <eggert@twinsun.com>
5576 * NEWS, doc/autoconf.texi (Particular Functions),
5577 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5578 is the inverse of localtime.
5580 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5582 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5583 (handle_exec_errors): New function. Work around $! being
5584 altered by WEXITSTATUS.
5585 (xqx, xsystem): Use handle_exec_errors.
5587 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5589 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5590 Do not call `_exit()', simply modify `$?'.
5591 (xsystem): Reset $! before running system, and check it afterward.
5592 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5593 63 for version mismatches.
5595 2003-05-23 Akim Demaille <akim@epita.fr>
5597 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5598 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5599 the middle of a line).
5600 * lib/m4sugar/m4sugar.m4: Likewise.
5601 Remove useless spaces in comments.

5605 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

5607 difference with a plain failure.
5608 * doc/autoconf.texi (Notices): Adjust.

5612 * Makefile.am, bin/Makefile.am, config/Makefile.am,

5617 Paul Eggert <eggert@twinsun.com>
5619 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5620 Remove `#include <stdlib.h>' from the list; we should never
5621 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5622 resulting namespace pollution would cause other tests to fail.
5623 Configure scripts run with some older versions of g++ and HP's
5624 aCC would fail due to such an #include. Problems reported by
5625 Matthew Mueller in <http://bugs.debian.org/120704> and by
5627 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5628 In the test, use the test declaration before including <stdlib.h>,
5629 as that's closer to how it'll be used.
5631 2003-05-23 Akim Demaille <akim@epita.fr>
5633 * doc/autoconf.texi (Header Portability): ucred.h.
5636 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5638 Overhaul Autotest's logging: generate separate log files
5639 in testsuite.dir/NNN/testsuite.log, and append them to
5640 testsuite.log instead of re-running the test verbosely.
5642 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5643 file descriptor, write 0 to at_status_file instead of setting
5644 at_status=0, initialize some new variables (at_status_file,
5645 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5646 to rerun the tests, instead append the at_group_log to the
5647 at_suite_log when a test fails.
5648 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5649 with the AS_MESSAGE_LOG_FD redirected to stdout.
5650 (AT_CLEANUP): save the output status in $at_status_file
5651 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5653 (AT_CHECK): since tests are run with a redirected stdout,
5654 and used to be re-run in verbose mode, turn some $at_verbose
5655 into echo, and don't redirect the output of testing stdout
5658 * lib/autotest/autoconf.texi (testsuite Scripts): Update

5779 2003-05-06 Akim Demaille <akim@epita.fr>
5781 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5782 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5783 by aclocal.m4 is changed it might require the importing of another
5784 m4 extension file, i.e., aclocal must be run.
5786 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5787 (&parse_args): Use --force with aclocal if required and supported.

5967 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
5968 to a shell that can handle redirection or quoting correctly.

6019 compiler says yeah, but preproc says nope, compiler is right.
6020 Conversely, prompt the reader to send a bug report to the

6034 2002-12-23 Paul Eggert <eggert@twinsun.com>
6036 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6037 innocuous variant befor including <limits.h> or <assert.h>. This
6038 works around a bug reported by Albert Chin: HP-UX 11i
6039 (and earlier versions) have a <limits.h> that declares
6040 gettimeofday and many other functions.
6042 2002-12-03 Paul Eggert <eggert@twinsun.com>
6046 * NEWS, configure.ac: Update version.
6048 * doc/fdl.texi: Upgrade to FDL version 1.2.
6050 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6051 nontrivially in main's body, so that f's external declaration is
6052 not optimized away in AIX. This should fix the bug reported by
6054 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.

6057 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6058 defined, to support freestanding compilers. This should fix the
6059 bug reported by Momchil Velkov in
6060 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6062 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6063 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
6064 obsolete AC_CHECK_TYPE. The missing empty arg was reported

6094 Update from masters.
6096 2002-11-14 Akim Demaille <akim@epita.fr>
6098 * Makefile.maint: Sync with Bison, i.e.:
6099 (po-check): Scan .l and .y files instead of the
6100 .c and the .h files that they generate. This fixes the bug
6101 reported by Tim Van Holder in:
6102 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6103 Look for N_ as well as for _. Try to avoid matching #define for

6117 2002-11-14 Kevin Ryde <user42@zip.com.au>
6119 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6120 than assigning in main, to avoid HP cc +O3 optimizing it away.
6122 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6124 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6125 option. Process --recheck after parsing all options. Pass -q
6126 option to configure on --recheck.
6127 (AC_OUTPUT): Pass -q from configure to config.status.
6128 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6129 arguments to record.
6130 * doc/autoconf.texi (config.status Invocation): Document
6131 config.status -q option.

6155 * tests/torture.at (Configuring subdirectories): Don't use grep
6157 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
6158 Reported by Ezra Peisach.
6160 2002-11-05 Akim Demaille <akim@epita.fr>
6162 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6164 We _have_ to stop using the old compatibility scheme that tried to
6165 avoid useless backslashes because Libtool 1.4.3 contains a
6166 AC_DEFINE([error_t], [int],
6167 [Define to a type to use for \`error_t' if it is not
6168 otherwise available.])
6169 We _have_ to quote the single quote and backslashes with \. The
6170 old compatibility scheme saw that ` was backslashed, and therefore
6171 did not quote the single quote. Hence before this patch, Autoconf

6626 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6627 aclocal invocation, as Gettext macros might not be visible to

6699 that were listed in the original autoscan.list.
6700 * lib/autoconf/headers.m4: Similarly with headers.
6701 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
6702 (.m4.m4f): Don't pass --prepend-include, since that's done by
6703 tests/autom4te itself.
6704 * lib/autoscan/Makefile.am: Include freeze.mk.
6705 (autoscan.list): New target --this file is no longer a source.
6706 (autoscan.pre): New file.
6708 2002-09-28 Akim Demaille <akim@epita.fr>

6713 tracking changes in autoscan.list.
6714 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6716 2002-09-28 Akim Demaille <akim@epita.fr>
6718 * lib/autoscan/functions, lib/autoscan/headers,

6721 * lib/autoscan/autoscan.list: this.
6722 * bin/autoscan.in (&init_tables): Adjust.
6724 2002-09-28 Akim Demaille <akim@epita.fr>
6726 * lib/autoscan/functions, lib/autoscan/headers,
6727 * lib/autoscan/identifiers, lib/autoscan/makevars,
6728 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
6729 `functions' line is now prefixed with `function:'.
6730 * bin/autoscan.in (&init_tables): Adjust.
6732 2002-09-28 Akim Demaille <akim@epita.fr>
6734 From now on, autoscan files must always map a macro name to a
6735 word: there is no `default' macro for autoscan.
6737 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6739 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6742 2002-09-28 Akim Demaille <akim@epita.fr>
6744 * bin/autoscan.in (%c_keywords): Remove.
6745 (&used): Keep only track of the words we might be interested in.

6753 * lib/autoscan/functions: Adjust.
6754 * doc/autoconf.texi (Particular Functions): Adjust.
6756 2002-09-27 Akim Demaille <akim@epita.fr>
6758 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
6760 Thanks to Bill Moseley and Paul Eggert.
6761 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
6762 the tmpdir must be created.
6763 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
6764 dir be in the build tree, instead of $TMPDIR.

6768 * bin/autoscan.in: Improve the comments.
6769 (&parse_args): Drop obsolete undocumented options.
6770 (&output_kind): Output warnings.

6774 2002-09-26 Akim Demaille <akim@epita.fr>
6776 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
6777 Reported by Ralf Corsepius.

6780 2002-09-26 Akim Demaille <akim@epita.fr>
6782 Single suffix rules and seperated dependencies are not portable.
6784 * doc/autoconf.texi (Installation Directory Variables): Update.
6785 (Limitations of Make): Some about `Single Suffix Rules and
6786 Separated Dependencies'.
6787 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6788 (ifnames, autoscan, autom4te): Un-factor into several rules.
6790 2002-09-25 Paul Eggert <eggert@twinsun.com>
6792 * BUGS (Interoperability bugs): New section. Mention libtool
6793 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
6795 2002-09-24 Paul Eggert <eggert@twinsun.com>
6797 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
6798 make handles suffix-rules differently from GNU make.
6800 * bin/Makefile.am (SUFFIXES, .in): Remove.
6801 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
6802 Move the body of the old .in rule here.
6804 2002-09-16 Akim Demaille <akim@epita.fr>
6806 i960 compilers create `b.out' files by default.
6807 Reported by Ralf Corsepius.
6809 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
6810 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
6812 2002-09-13 Paul Eggert <eggert@twinsun.com>

6815 reference to `struct timezone' in the description of
6818 2002-09-13 Akim Demaille <akim@epita.fr>
6822 * config/config.sub, config/config.guess: Update.
6823 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
6824 * Makefile.am: Adjust.
6826 2002-09-13 Akim Demaille <akim@epita.fr>
6828 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
6829 reading config.log when the compiler is rejected.
6830 Suggested by Guido Draheim.
6832 2002-09-13 Akim Demaille <akim@epita.fr>
6834 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6835 (chdir_init) might hang when stat'ing mounted directories.
6836 Reported by Vance Shipley.
6838 2002-09-12 Akim Demaille <akim@epita.fr>
6840 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6843 2002-09-12 Akim Demaille <akim@epita.fr>
6845 * doc/autoconf.texi (Defining Symbols): Present two different
6846 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
6847 difference between 1 argument calls, and 2-3 argument calls.
6849 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
6851 * doc/autoconf.texi: Review grammar and punctuation.
6853 2002-09-11 Paul Eggert <eggert@twinsun.com>
6855 * doc/autoconf.texi: Fix minor formatting, spelling, and
6857 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6858 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6861 2002-09-11 Akim Demaille <akim@epita.fr>
6863 * doc/autoconf.texi (Questions): Rename as...
6865 (Defining Directories): New.
6867 2002-09-09 Akim Demaille <akim@epita.fr>
6869 * doc/autoconf.texi (Making testsuite Scripts): Update.
6870 Suggested by Nishio Futoshi.
6872 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
6874 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
6875 plain `@' is wanted.
6877 2002-09-09 Akim Demaille <akim@epita.fr>
6879 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6880 `duplicates', since the algorithm was too naive and could keep
6881 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
6882 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6883 Reported by Ralf Corsepius.
6884 * tests/torture.at (Configuring subdirectories): Exercise these
6887 2002-09-09 Akim Demaille <akim@epita.fr>
6889 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
6890 looking for a replacement file.
6891 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
6892 directory is relative.
6893 * doc/autoconf.texi (Generic Functions): Clarify the replacement
6894 directory definition.
6895 Reported by Andreas Schwab and Jim Meyering.
6897 2002-09-06 Akim Demaille <akim@epita.fr>
6899 * doc/autoconf.texi (Setting Output Variables): Clarify what
6900 precious variables are.
6901 Suggested by Pontus Skoeld.
6903 2002-09-05 Akim Demaille <akim@epita.fr>
6905 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6906 (ifnames, autoscan, autom4te): Since we don't only depend on
6907 configure.ac variables (such as VERSION etc.), but also on prefix
6908 and so forth, depend on Makefile, not configure.ac.
6909 Reported by Alexandre Duret-Lutz.
6910 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6912 2002-09-05 Kevin Ryde <user42@zip.com.au>
6914 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
6915 doesn't seem to be confined to ia64, just say "some versions".
6917 2002-09-04 Akim Demaille <akim@epita.fr>
6919 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
6921 * Makefile.am (maintainer-clean-local): Remove.
6922 (MAINTAINERCLEANFILES): Remove COPYING.
6924 2002-09-03 Paul Eggert <eggert@twinsun.com>
6926 * doc/autoconf.texi (Configuration Commands): Remove obsolete
6927 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
6930 2002-09-03 Akim Demaille <akim@epita.fr>
6932 * configure.ac: Bump to 2.53d.
6933 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
6934 as of today, on Automake's team suggestion.
6936 2002-09-03 Akim Demaille <akim@epita.fr>
6940 2002-09-02 Akim Demaille <akim@epita.fr>
6942 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
6944 * configure.ac: Disable SITE_MACRO_DIR.
6946 2002-09-02 Jim Meyering <meyering@lucent.com>
6948 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
6949 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
6950 Also, tweak grammar: s/make sure to/be sure to/.
6952 2002-09-02 Paul Eggert <eggert@twinsun.com>
6954 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
6955 directory names are generally preferable to physical names.
6957 2002-09-02 Akim Demaille <akim@epita.fr>
6959 * lib/Autom4te/General.pm (&update_file): s/die/error/.
6960 Reported by Raja R. Harinath.
6961 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
6962 * bin/autoupdate.in: Use error instead of die.
6964 2002-09-01 Paul Eggert <eggert@twinsun.com>
6966 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
6967 ordinary shell concatenation rather than echo+tr+sed command that
6968 runs afoul of a long-line-related sed bug in Solaris 8.
6970 * bin/autoheader.in (parse_args): --warning -> --warnings.
6972 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
6973 stdout, as traditional "ls" does.
6974 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
6975 _AC_COMPILER_EXEEXT_O): Likewise.
6976 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
6978 * bin/autoconf.as: Add --prepend-include option. This patch was
6979 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
6980 but bin/autoconf.in is generated automatically from bin/autoconf.as.
6982 * bin/autoconf.in, configure: Regenerate.
6984 * doc/autoconf.texi (Special Shell Variables): Mention
6985 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
6987 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
6988 MAILPATH and set PS1, PS2, PS4 to default values, to work
6989 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
6990 For LC_ALL etc, first try to set to "C" as POSIX requires and as
6991 the Autoconf documentation specifies; fall back to "unset" only if
6992 this fails. Use a shell for-loop for this rather than an m4 loop,
6993 to shorten the output script.
6995 2002-08-30 Paul Eggert <eggert@twinsun.com>
6997 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
6998 1003.1-2001's requirements for CDPATH. Give a simpler workaround
6999 for the CDPATH problem. Document PWD.
7000 (Limitations of Builtins): Document the problem that "cd $foo" and
7001 "ls $foo" may refer to different directories in shells conforming
7002 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7003 example, since the old example is now out of date.
7005 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7006 FOO" and "ls FOO" talk about different directories; this catches
7007 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7010 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7011 of rolling our own unset.
7012 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7013 in practice we needn't worry about CDPATH if unset doesn't work.
7015 * Makefile.in, aclocal.m4, bin/Makefile.in,
7016 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7017 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7018 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7019 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7020 tests/Makefile.in: Regenerate with Automake 1.6.3.
7022 * config/config.guess, config/config.sub, config/mkinstalldirs:
7025 * configure: Regenerate with self.
7027 2002-08-30 Kevin Ryde <user42@zip.com.au>
7029 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7032 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7034 * bin/autom4te.in (Request::load): Correctly test for "do" read
7037 2002-08-29 Akim Demaille <akim@epita.fr>
7039 * lib/Autom4te/General.pm (&xqx): New.
7040 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7041 hand, which is not portable.
7043 * bin/autom4te.in: Use them.
7044 Use &error instead of die.
7045 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7048 2002-08-17 Paul Eggert <eggert@twinsun.com>
7050 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7051 default list of compilers to try, since it was long ago superseded
7052 by the ksh fc builtin. Suggested by Steven G. Johnson.
7054 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7056 * doc/autoconf.texi (Invoking autom4te): End the option table,
7057 fixing a bug introduced by the previous patch.
7058 (Limitations of Make): Add a 'target lookup' subentry in the
7059 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7061 2002-07-29 Mark D. Roth <roth@feep.net>
7063 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7064 options and use $AUTOM4TE_PATH.
7065 * doc/autoconf.texi: Remove documentation of autom4te
7066 --include-envvar and --site-macro-subdir options and document
7067 use of $AUTOM4TE_PATH.
7068 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7069 arguments from each language section.
7071 2002-07-29 Paul Eggert <eggert@twinsun.com>
7073 * doc/install.texi: Include copyright symbol in copyright notice.
7075 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7077 (AM_MAKEINFOFLAGS): New macro.
7078 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7079 * Makefile.am (INSTALL): Use the new macros.
7080 Use -o rather than --output, since "missing" does not grok --output.
7082 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7084 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7085 comments do not always work. Never trust the exit status of
7088 2002-07-24 Kevin Ryde <user42@zip.com.au>
7090 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7091 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7093 2002-07-23 Paul Eggert <eggert@twinsun.com>
7095 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7096 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7097 apparently treats PATH="nonexistent" as if it contained ".".
7098 Bug reported by Stefan `Sec' Zehl.
7100 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7102 * doc/autoconf.texi (Limitations of Make): Mention the special
7103 handling of the obj/ directory by BSD make.
7105 2002-07-20 Kevin Ryde <user42@zip.com.au>
7107 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
7110 2002-07-19 Akim Demaille <akim@epita.fr>
7112 * doc/autoconf.texi (Function Portability): `exit'.

7139 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
7140 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
7142 2002-07-17 Russ Allbery <rra@stanford.edu>
7144 * doc/autoconf.texi (Initializing configure): Clarify the
7145 description of the tarname default.
7147 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>

7174 * bin/autoupdate.in: Add --prepend-include option.
7175 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
7176 macro directory, remove note that include path directories are
7177 used in reverse order, and document --prepend-include option.
7178 * lib/autom4te.in: Use --prepend-include instead of --include.
7179 * tests/wrapsh.in: Use --prepend-include instead of --include.
7181 2002-07-17 Akim Demaille <akim@epita.fr>

7372 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7373 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7374 Both macros now accept an optional source-dir arg.
7375 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7377 * NEWS: Document this.
7378 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7380 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7381 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,

7392 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7393 and it causes a 'test' syntax error if it fails.
7394 Bug reported by Stephen Gildea.
7396 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7397 If prototypes are supported, use them to check this at compile-time,
7398 instead of trying to check it at run-time. If we must do a run-time
7399 check, assume that setvbuf is standard when cross-compiling, as
7400 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7401 Bug reported by Paul D. Smith.
7403 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7404 argument specifying location of getloadavg.c. This removes a
7405 FIXME. This idea was taken from Jim Meyering's implementation in
7407 * doc/autoconf.texi (Particular Functions): Document this.
7408 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7409 that's what the code does; this fixes a bug reported by

7414 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7415 autopoint instead of gettextize.
7416 ($uses_alocal): Rename as...
7417 ($uses_aclocal): this.
7418 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7419 Suggested by Bruno Haible.

7425 2002-04-29 Paul Eggert <eggert@twinsun.com>
7427 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7428 files to be 1 second older; just set them to be the same time.
7429 Also, sleep 1 second after the first aclocal, to work around
7430 problems with sub-second time stamps on the input files.
7432 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7434 * doc/autoconf.texi: Mention "set -e -x" lossage

7443 2002-04-29 Akim Demaille <akim@epita.fr>
7445 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7446 of lack of $LINENO support, then the test will compare the $LINENO
7447 in testsuite vs. the lineno in the test file. This is wrong, of
7449 Be sure to protect it.
7450 Reported by Patrick Welche.
7452 2002-04-25 Akim Demaille <akim@epita.fr>
7454 * doc/autoconf.texi (Obsolete Macros): Typo.
7455 Reported by Vladimir Volovich.
7457 2002-04-25 Akim Demaille <akim@epita.fr>
7459 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7460 than some of the input files, hence, on the second run of aclocal,
7461 if some of its input are younger, make them older.
7462 Suggested by Paul Eggert.
7464 2002-04-25 Akim Demaille <akim@epita.fr>
7466 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

7472 and ac_subst_vars be sh variables containing the list of
7473 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7475 (_AC_INIT_PREPARE): Use them to log them.
7476 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7477 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7478 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7479 _AC_SUBST_FILES and _AC_SUBST_VARS.

7482 2002-04-24 Akim Demaille <akim@epita.fr>
7484 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7485 autoheader, so that automake does not complain about a missing
7486 config.h.in that was to be created.
7488 2002-04-23 Akim Demaille <akim@epita.fr>

7705 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7706 (AS_SHELL_SANITIZE): Invoke it.
7707 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
7709 2002-03-26 Akim Demaille <akim@epita.fr>
7711 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
7713 2002-03-26 Akim Demaille <akim@epita.fr>
7715 * doc/autoconf.texi (Introduction): The GNATS base moved.
7717 2002-03-25 Paul Eggert <eggert@twinsun.com>
7719 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7720 as POSIX requires, as it doesn't work with Zsh.
7721 * doc/autoconf.texi (Assignments): Document the problem.
7723 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7725 * doc/autoconf.texi (Limitations of Make): Mention more issue
7726 about VPATH, overriding of macros in sub-makes, and handling of
7729 2002-03-21 Paul Eggert <eggert@twinsun.com>
7731 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7732 problem with here-document buffer boundaries.
7734 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7735 when reinvoking the shell, to work around problems with installers
7736 who put strange things like "cd" commands in their environments.
7738 2002-03-19 Akim Demaille <akim@epita.fr>
7740 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

7745 * bin/autoscan.in (scan_file): Specify the location in `&used'
7749 2002-03-19 Akim Demaille <akim@epita.fr>
7751 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
7752 From Nishio Futoshi.
7754 2002-03-19 Akim Demaille <akim@epita.fr>
7756 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

7760 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7761 (Limitations of Usual Tools): Add mkdir section.
7763 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7764 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7765 back on AS_DIRNAME to compute prefixes otherwise; this is
7766 roughly what mkinstalldirs does. That way, we need not have
7767 our own filename disassembler. The old disassembler did not
7768 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7770 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7771 Create at_test_all by a series of assignments,
7772 not by a single assignment of a long string. The latter causes ksh
7773 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7774 presumably because of a buffer overrun.
7776 2002-03-14 Paul Eggert <eggert@twinsun.com>
7778 * lib/autotest/general.m4 (at_times_skip):
7779 Renamed from at_times. Now a boolean.
7780 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7781 says 'times: not found'.
7783 2002-03-14 Akim Demaille <akim@epita.fr>
7785 * bin/autoreconf.in (&study_gettextize): New.
7786 (&autoreconf): Handle newest gettextize.
7787 Rerun aclocal if needed.
7788 Suggested by Andreas Schwab.

7813 does not do it if --with-lispdir is given.

7819 2002-03-08 Akim Demaille <akim@epita.fr>

7822 subdirectory should exist.
7824 2002-03-08 Akim Demaille <akim@epita.fr>
7826 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
7828 2002-03-08 Akim Demaille <akim@epita.fr>
7830 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7831 aliases the actual variables, and modifications of the former
7834 2002-03-08 Akim Demaille <akim@epita.fr>
7836 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7837 because of C-c: have m4 output in tmp files, then mv them.
7839 2002-03-08 Akim Demaille <akim@epita.fr>
7841 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
7842 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,

7858 2002-03-04 Akim Demaille <akim@epita.fr>
7860 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
7861 * lib/autoconf/general.m4 (AC_INIT): More informative error
7864 2002-03-04 Akim Demaille <akim@epita.fr>
7866 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
7869 2002-03-04 Akim Demaille <akim@epita.fr>
7871 * doc/autoconf.texi (Transforming Names): Equality between target
7872 and host is irrelevant.
7873 (Specifying Names, Canonicalizing): Remove all references to the
7874 backward compatibility hooks. Rather, collect them all into...
7875 (Hosts and Cross-Compilation): this new section.
7876 * doc/install.texi (System Type): Ditto.
7877 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7878 that `--host' implies cross-compilation.
7880 2002-03-04 Akim Demaille <akim@epita.fr>
7882 * doc/autoconf.texi (Evaluation Macros): New.
7883 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7885 (_m4_foreach): Define the variant with immediate evaluation so
7886 that it contains exactly the items, not an expression which
7887 evaluation is the current item.
7888 (m4_re_string, m4_re_word): Don't over quote them.
7890 2002-03-04 Akim Demaille <akim@epita.fr>
7892 Instead of having stacking `shift's evaluated at the end, let
7893 `foreach' loops immediately evaluate them.
7895 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7896 $*. This is the n-th time I change my mind, but hopefully this is
7899 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7901 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7902 it was only a hack for m4_text_wrap.
7903 (m4_car2): Remove, replaced by...
7905 (_m4_foreach): Adjust.
7906 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
7907 m4_bpatsubst for clarification.
7909 2002-03-04 Akim Demaille <akim@epita.fr>
7911 * doc/autoconf.texi (Changequote is Evil): New.

7958 Fix Autoconf PR/207:
7959 AC_PREFIX_PROGRAM fails with dashed program names
7961 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
7962 variable when looking for the prefix program.
7963 Now it also works for shell variables.

7973 case/esac, some shells don't support it.
7974 Reported by Zack Weinberg.

7980 sure not to introduce newlines in at_groups.

7995 cross-compilers, too. This undoes some of the most recent change
7998 2002-02-05 Akim Demaille <akim@epita.fr>
8000 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

8022 * bin/autom4te.in (&parse_args): Implement `frozen files are
8023 optional are the sum of the previous files on the command line'.
8024 Also, pass `--reload-state=' on them, so...
8026 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8027 (M4sh): Rely on M4sugar.
8028 (Autotest, M4sh, M4sugar): Use frozen files.

8065 2002-01-28 Akim Demaille <akim@epita.fr>
8067 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8068 AUTOTEST_PATH *after* it was set.
8069 Don't put `.' in the PATH: the user should be precise and `./' if
8070 needed. In addition, given that the test suite does some `cd', if
8071 `.' is in the path, the `tested programs' sections will report
8072 programs found in the test suite's directory, while during the
8073 tests (performed in their own directory), these programs are no
8074 longer visible. In other words, the results is confusing and
8076 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

8145 * tests/Makefile.am (package.m4): New.
8146 EXTRA_DIST it since its a source.

8151 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8152 and PACKAGE_BUGREPORT from here...
8153 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8155 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8156 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8157 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8158 * tests/tools.at (autoheader): Adjust.
8159 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8161 2002-01-06 Akim Demaille <akim@epita.fr>

8183 trailing files, don't apply `-rf' to files which might not be
8184 created by configure (core, core.*, and *.core), but just `rm -f'.
8185 Suggested by Jonathan Kamens.
8187 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8189 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

8193 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8195 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

8199 abs_srcdir, top_srcpath to abs_top_srcdir.

8224 Remove $filepath, useless.
8225 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@

8227 Split the input line on spaces and then look for tokens.
8228 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison

8240 * lib/autoscan/headers: errno.h is portable.
8242 2001-11-26 Akim Demaille <akim@epita.fr>
8244 * bin/autoscan.in (used): New.
8247 2001-11-26 Akim Demaille <akim@epita.fr>
8249 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8251 (&scan_sh_file): Remove a duplicate pattern.
8252 (&check_configure_ac): Use long options.
8253 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8255 2001-11-26 Akim Demaille <akim@epita.fr>
8257 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8258 Before, having a line containing the opening of a multi line
8259 comment made the whole line be ignored.
8261 2001-11-26 Akim Demaille <akim@epita.fr>
8263 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8264 (testsuite Scripts): Be one of its subsection.
8265 (Autotest Logs): New.
8267 2001-11-26 Akim Demaille <akim@epita.fr>
8269 Test groups are now run two directories deeper.
8271 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8272 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8274 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8275 top_srcdir, builddir and top_builddir.
8276 Use `at_*dir' relatively to the directory containing the
8277 suite, use `*dir' when relatively to the current group dir.
8279 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8281 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8282 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8283 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8286 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8288 * doc/autoconf.texi (Using System Type): Add an example of `case
8289 $host' usage so people quit using `case $target' everywhere.
8291 2001-11-22 Akim Demaille <akim@epita.fr>
8293 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8294 spotted by Jim Meyering.
8296 2001-11-16 Paul Eggert <eggert@twinsun.com>
8298 This patch implements a `long double' suggestion by Oliver Kiddle.
8300 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8301 static, to catch errors if the value isn't known at compile-time
8302 and the compiler supports dynamic arrays. Change its name from
8303 `_array_' to `test_array' to avoid potential name clashes.
8304 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8305 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8306 better than double. Catch a bug in GCC 2.95.2 x86.
8307 * doc/autoconf.texi (C Compiler): Document the above.
8310 2001-11-13 Akim Demaille <akim@epita.fr>
8312 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8314 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8316 2001-11-13 Akim Demaille <akim@epita.fr>
8318 * lib/autotest/general.m4 (AT_INIT): After having run the test
8319 group, go back to the initial directory, not to at_suite_dir.
8321 2001-11-13 Akim Demaille <akim@epita.fr>
8323 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8324 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8325 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8327 (AT_CHECK_CONFIGURE): Use absolute paths.
8328 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8329 The problem is still the old one: there is no means in M4 (that I
8330 know about) to create a defining macro, because there is no means
8331 to create `$1' etc., therefore, the defining macro ``swallows''
8332 all the arguments meant to the defined macro.
8334 2001-11-13 Akim Demaille <akim@epita.fr>
8336 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8337 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8339 * tests/aclocal.m4: Remove, as it is no longer used.
8341 2001-11-13 Akim Demaille <akim@epita.fr>
8343 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8344 variable names when referring to a single test group, or to
8345 `suite' when referring to the whole test suite.
8346 `at_last_test' is removed: m4 compute at_format itself.
8347 (at_stdout, at_stder1, at_stderr): New variables.
8348 (AT_CHECK): Use them.
8350 2001-11-13 Akim Demaille <akim@epita.fr>
8352 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8354 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8355 Do it as soon as a test fails, don't wait till the end of the test
8357 Don't remove $as_me.[0-9]*, since these files no longer exist.
8359 2001-11-13 Akim Demaille <akim@epita.fr>
8361 * tests/tools.at: Use absolute paths, since we are no longer run
8364 2001-11-13 Akim Demaille <akim@epita.fr>
8366 Now that tests are running in their own private dir, there is no
8367 need to list the files to remove at the end of tests groups.
8369 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8370 (AT_data_files, at_data_files): Remove.
8371 (AT_CLEANUP, AT_DATA): Simplify.
8373 Remove the group dir if !debug && !failed.
8374 * tests/atspecific.m4: Adjust.
8376 2001-11-13 Akim Demaille <akim@epita.fr>
8378 Start a new layout for Autotest: `testsuite' creates
8379 `testsuite.dir' in which the at-check-line etc. files are to be
8380 found, and `testsuite.dir/003' where the test group 3 is run.
8382 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8383 at_check_line_file, at_format, at_test_normalized, at_group_dir
8385 Create the directories.
8386 Use absolute paths for at- files.
8389 2001-11-11 Michael Matz <matz@kde.org>
8391 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8393 (m4_car): Properly quote arguments.
8395 2001-11-13 Akim Demaille <akim@epita.fr>
8397 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8398 with stricter rules on LIBOBJS.
8400 2001-11-12 Paul Eggert <eggert@twinsun.com>
8402 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8403 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8406 2001-11-12 Akim Demaille <akim@epita.fr>
8408 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8410 2001-11-12 Akim Demaille <akim@epita.fr>
8412 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8413 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8414 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8415 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8416 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8417 specify to what the macro should be defined (typically to 1).
8419 2001-11-12 Akim Demaille <akim@epita.fr>
8421 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8424 2001-11-12 Akim Demaille <akim@epita.fr>
8426 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8427 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8428 definition used by Automake where LEX is +/- "${missing} lex" and
8429 `missing' itself contains variables.
8431 2001-11-12 Akim Demaille <akim@epita.fr>
8433 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8434 Now that M4sh pushes BODY, the comments were output at the end of
8437 2001-11-08 Akim Demaille <akim@epita.fr>
8439 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8440 that we can trace macros from aclocal.m4.
8441 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8442 obsoleted, and redirect to the former anyway.
8443 Reported by Ralf Corsepius.
8445 2001-11-08 Akim Demaille <akim@epita.fr>
8447 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8448 processed only if present.
8449 * tests/torture.at (Configuring subdirectories): Use autoreconf
8450 instead of successive calls to autoconf.
8451 Add a nonexistent subdirectory to exercise the patch above.
8452 Reported by Ralf Corsepius.
8454 2001-11-08 Kevin Ryde <user42@zip.com.au>
8456 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8457 doesn't accept .S files.
8459 2001-11-07 Akim Demaille <akim@epita.fr>
8461 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8462 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8463 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8464 * bin/autom4te.in (warn_forbidden): New.
8465 (handle_output): Use it.
8466 Read m4_pattern_forbid with messages.
8468 2001-11-05 Akim Demaille <akim@epita.fr>
8470 * bin/autom4te.in (--normalize): Remove.
8471 * lib/autom4te.in: Adjust.
8473 2001-11-05 Akim Demaille <akim@epita.fr>
8475 * tests/Makefile.am (testsuite): Rename this target as...
8476 ($(TESTSUITE)): this.
8479 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8481 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8482 the --prefix option, also remove it's argument.
8484 2001-11-05 Akim Demaille <akim@epita.fr>
8486 * doc/autoconf.texi (testsuite Invocation): Update.
8487 (Writing testsuite.at): Update.
8489 2001-11-03 Akim Demaille <akim@epita.fr>
8491 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8493 2001-11-03 Akim Demaille <akim@epita.fr>
8495 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8496 (&file_name_is_absolute): New, wrappers around routines from
8498 Use and export them.
8499 (&find_configure_ac): Optionally take a directory where to look at.
8500 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8502 Default @ARGV to `.', not find_configure_ac.
8503 (&autoreconf): Argument is a directory.
8504 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8505 * doc/autoconf.texi (autoreconf Invocation): Update.
8507 2001-11-03 Akim Demaille <akim@epita.fr>
8509 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8510 (@export_forward_subs): New.
8511 Add basename, dirname, and fileparse.
8513 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8514 Don't look for aclocal flags if we already know aclocal is not
8516 Move aclocal.m4t only if it exists.
8517 Reported by Ezra Peisach.
8519 2001-11-03 Akim Demaille <akim@epita.fr>
8521 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8522 passed on command line, defaulting to ./configure.ac if present.
8523 (&maybe_autoreconf, File::Find): Remove, unused.
8524 (&autoreconf): If autoconf is not used, don't try to trace.
8526 2001-11-02 Akim Demaille <akim@epita.fr>
8528 * configure.ac: Bump to 2.52g.
8530 2001-11-02 Akim Demaille <akim@epita.fr>
8534 2001-11-02 Akim Demaille <akim@epita.fr>
8536 * config/config.guess, config/config.sub, doc/standards.texi:
8537 * config/lispdir.m4: Update from masters.
8538 * configure.ac: Bump to 2.52f.
8540 2001-11-02 Akim Demaille <akim@epita.fr>
8542 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8543 Don't run aclocal when aclocal.m4 is not from aclocal.
8545 Don't run libtoolize and gettextize if --install is not given.
8547 2001-11-01 Paul Eggert <eggert@twinsun.com>
8549 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8550 be invoked before _AS_LINENO_PREPARE.
8551 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8552 than character ranges.
8554 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8555 invoking AS_BASENAME. Set the locale variables to 'C' if
8556 possible, as POSIX requires this to get the traditional
8558 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8560 2001-10-31 Paul Eggert <eggert@twinsun.com>
8562 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8563 with {}, as that triggers a bug in Bash 2.05.
8565 (_AS_LINENO_PREPARE): Use Sed rather than
8566 Awk. Fix the sed prepass to work even if there are multiple
8567 instances of $LINENO on the same line. Do not substitute for
8568 other variables like $LINENOT. Do not check file dates; such a
8569 check is unreliable on sufficiently fast machines, and removing
8570 the check makes the code simpler and more reliable. Check for
8571 output and chmod failures.
8573 * doc/autoconf.texi (Special Shell Variables): Document
8576 2001-10-31 Akim Demaille <akim@epita.fr>
8578 * tests/Makefile.am (atconfig): Remove this target, Automake
8581 2001-10-31 Akim Demaille <akim@epita.fr>
8583 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8584 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8585 provided, while it is optional.
8586 * configure.ac: Adjust.
8588 2001-10-26 Paul Eggert <eggert@twinsun.com>
8590 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8591 lib/Autom4te/Struct.pm:
8592 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8595 * doc/autoconf.texi (Special Shell Variables): Document some
8596 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8598 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8599 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8600 eval $LINENO is not portable in practice.
8602 2001-10-24 Akim Demaille <akim@epita.fr>
8604 * lib/Autom4te/General.pm (backname): New.
8606 2001-10-24 Akim Demaille <akim@epita.fr>
8608 * m4/: Remove, merged into...
8611 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8613 * doc/autoconf.texi (Shellology): Mention the problems with bash
8614 2.05's use of ANSI quoting in its `set' builtin.
8616 2001-10-22 Paul Eggert <eggert@twinsun.com>
8618 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8619 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8620 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8621 POSIX decided to standardize on the int flavor of strerror_r.
8622 Always do char* test, as there's no reason not to.
8623 Assign to a char* var, to catch strerror_r that returns int*.
8625 * doc/autoconf.texi (Particular Functions):
8626 Document the above changes. Also, document the fact that
8627 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8629 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8631 2001-10-20 Akim Demaille <akim@epita.fr>
8633 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
8634 the executable was missing from the log.
8636 2001-10-20 Akim Demaille <akim@epita.fr>
8638 * lib/Autom4te/General.pm (&update_file): If destination is
8639 unchanged, remove the source.
8640 (&up_to_date_p): Don't be verbose, be debug.
8641 * bin/autoreconf.in: No longer support --m4dir.
8642 (&autoreconf): Display the full path of the configure.ac we are
8645 Be sure to honor --force with gettextize.
8647 * doc/autoconf.texi: Adjust.
8649 2001-10-20 Akim Demaille <akim@epita.fr>
8651 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8653 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8654 `intl' is already present, as it refuses unless --force.
8655 (&parse_args): Use -I, --include instead of the old Autoconf
8657 ($localdir, $autoconf_dir): Remove.
8659 (&maybe_autoreconf): New, to preserve $_ for File::Find.
8661 2001-10-19 Jens Petersen <petersen@redhat.com>
8663 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
8664 * doc/autoconf.texi (Particular Programs): Likewise.
8666 2001-10-19 Akim Demaille <akim@epita.fr>
8668 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
8669 file in @configure_input@.
8670 Don't mention `automatically' in addition to `generated'.

8682 configure.ac being studied.
8684 2001-10-18 Paul Eggert <eggert@twinsun.com>
8686 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
8687 long, to work around a bug in the HP C compiler version HP92453-01
8690 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
8691 (AS_BASENAME_EXPR): New macro.
8692 (AS_BASENAME_SED): Do not assume GNU sed semantics.
8693 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
8694 and fall back on 'sed' only if the other two fail. This makes
8695 AS_BASENAME act more like AS_DIRNAME.
8696 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
8697 contains white space.
8698 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
8699 Use AS_DIRNAME, since I think it's now DOS-friendly.
8700 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
8701 Allow "dirname //FOO" to return either / or //, as POSIX allows
8704 2001-10-10 Akim Demaille <akim@epita.fr>
8706 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
8707 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
8710 2001-10-10 Akim Demaille <akim@epita.fr>
8712 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
8714 (_AS_ECHO_N): AS_REQUIREs it.
8716 2001-10-10 Akim Demaille <akim@epita.fr>
8718 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
8719 (AC_INCLUDES_DEFAULT): Move to...

8749 * tests/tools.at (AT_CHECK_PERL_SYNTAX): Check autoreconf.
8750 (Syntax of the shell scripts): Don't.
8751 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
8752 bother with $force since...
8753 * lib/Autom4te/General.pm: does.
8755 2001-10-08 Akim Demaille <akim@epita.fr>
8757 * bin/autoreconf.in: Rewrite in Perl.

8968 * doc/autoconf.texi (autoconf Invocation): Fix the example:
8969 AC_TRY_RUN is about compilation, not shell commands.

9166 to expr, by parenthesizing initial integers that might be negative.
9168 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9169 now merely checks whether it is an error to pass an argument
9172 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9173 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9174 whether it is a (compile-time) error to pass an argument to

9195 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9196 * tests/base.at: Fixed the expected responses. The old ones were
9198 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9199 the documentation claims it should (and how it behaved in 2.13).

9225 program version string doesn't match the package's.
9226 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9229 2001-09-17 Paul Eggert <eggert@twinsun.com>
9231 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9232 Allow expression to return any value that can fit into unsigned long

9237 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):

9245 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9246 or CFLAGS=-O5. In that case, the linker has a relaxed view of

9413 2001-09-05 Akim Demaille <akim@epita.fr>
9415 Be ready to handle filenames as stupid as `dnl.at', for if even
9416 the maintainer is dumb enough to do that...
9418 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9419 excellence in M4 quotation: consider `__file__' is active.

9601 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9603 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9604 indeed related to running the test suite, while passing

10198 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10199 extension (needed on BeOS). Reported by Guido van Rossum.
10201 2001-08-09 Akim Demaille <akim@epita.fr>
10203 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10205 2001-08-07 Akim Demaille <akim@epita.fr>
10207 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10209 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10210 No need to remove the files before and after the each test, before
10211 each test and at the end of the suite is enough.
10212 Display only the children `times', not the shell's.
10213 If the test failed or was skipped, at-times is not available.
10215 2001-08-07 Akim Demaille <akim@epita.fr>
10217 Always produce testsuite.log, including when there are no
10218 failures. This helps getting information on skipped tests, and
10219 duration of the tests. Err, implement the latter btw.
10221 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10222 Dump information on the first run of each test.
10223 (AT_CLEANUP): Create `at-times' containing the duration of the
10226 2001-08-07 Akim Demaille <akim@epita.fr>
10228 The use of `dumpstat' revealed that `len' was used although it
10229 should not. m4_text_wrap was using it, but in the Autoconf world
10230 where it is legal. Hence (i) test M4sh in its own world, not
10231 Autoconf's, and (ii), ahem, fix the bug :)
10233 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10234 does not like `' instead of [].
10235 (AT_INIT): Forbid `^_?AT_'.
10236 And don't output such tokens.
10237 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10238 `script.as', and `autom4te.cache'.
10239 Remove `empty' and `macro' which are no longer used.

10263 Don't rely on M4sugar outputting the patterns in files, since we

10268 * bin/autom4te.in (@Request::includes): Remove, unused.

10277 2001-08-04 Akim Demaille <akim@epita.fr>
10279 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&

10298 2001-08-04 Akim Demaille <akim@epita.fr>
10300 Don't let autom4te compute the `include' traces several times:
10301 first check that the trace cache file is up to date, and then
10302 compare its timestamp with that of the output.
10304 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10305 the preamble. Don't require 5.005 as Autom4te::General does it,
10306 and better yet (use `use', not `require'!).
10307 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10308 Class::Struct as Autom4te::Struct.
10309 * lib/Autom4te/General.pm (File::stat): Use it.
