3 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5 Don't use the term "thread-safe" to talk about mkdir race
6 conditions, since the problem is more a process than a thread
7 issue. Problem reported by Stepan Kasal in:
8 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
9 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10 the test for 'install' more closely. Look at MKDIR_P first.
11 Look in the PATH, and at /opt/sfw/bin.
12 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
13 Don't bother to try mkdir -p, since we already check mkdir --version;
14 just look at the version number. (There's no easy way to check
15 for race-free implementations.)
16 * tests/tools.at (autoconf: subdirectories): Adjust to above
17 changes, since MKDIR_P now might end in "/mkdir -p".
19 * doc/autoconf.texi (autoheader Invocation): Mention that the
20 first arg of AC_DEFINE_UNQUOTED must not be a literal.
21 Problem reported by Ben Pfaff in
22 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
24 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
25 * doc/autoconf.texi (Special Chars in Variables): New section.
26 (Preset Output Variables): Warn about special chars in CPPFLAGS.
27 (Installation Directory Variables): Quote $(datadir) better.
28 (Limitations of Builtins): Describe some of eval's trickiness.
30 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
31 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
32 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
33 in front of every arg, not just trailing args. Quote apostrophes.
34 (_AC_EVAL_ECHO): New macro.
35 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
36 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
37 removed.
38 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
39 exposed by quoting of eval argument. Put the command on line line
40 so it logs better.
41 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
42 (_AC_PATH_X, AC_PATH_X): Quote more safely.
43 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
44 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
45 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
46 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
47 Use eval more safely.
48 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
49 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
50 to be replaced.
51 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
52 lines, exposed by quoting of eval argument.
54 2006-05-26 Stepan Kasal <kasal@ucw.cz>
55 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
57 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
58 initialization of `ac_cv_exeext', do not override it if it was
59 already set, unless it was set to `no', for compatibility with
60 Autoconf-2.13, and comment this.
61 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
62 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
63 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
64 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
65 Document that this test may be overridden by setting
66 `ac_cv_exeext'.
68 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
70 Revert these two patches:
72 2006-04-06 Eric Blake <ebb9@byu.net>
73 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
74 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
75 2006-04-01.
77 2006-04-01 Stepan Kasal <kasal@ucw.cz>
78 Clean up _AC_COMPILER_EXEEXT* macros.
79 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
80 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
81 ac_file to the name of the default output file and call
82 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
83 initial `rm' of the candidate files...
84 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
85 the same list in subsequent `rm' calls, and for the temporary
86 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
87 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
88 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
89 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
90 no longer needed) by libtool. Make it a cache check.
91 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
92 copied here by mistake.
93 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
94 _AC_COMPILER_EXEEXT.
95 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
96 _AC_COMPILER_OBJEXT directly.
97 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
99 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
101 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
102 Fix description of how the buggy `sed' works.
104 2006-05-25 Noah Misch <noah@cs.caltech.edu>
106 Sync from Automake:
108 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
109 ENOLCK. Only mention `make -j' when applicable. Only raise
110 fatal errors when `make -j' is involved. Improve error message.
112 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
114 * doc/autoconf.texi (Here-Documents): We now know more about
115 the variable expansion in here documents bug.
116 Thanks to Tim Rice and Stepan Kasal.
118 * doc/autoconf.texi (Making testsuite Scripts): Add an example
119 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
121 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
123 * tests/autotest.at (Multiline command from M4 expansion):
124 No failure to be expected if the shell quotes newlines in
125 commands in the `set -x' output. Report by Tim Rice.
126 * THANKS: Update.
128 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
130 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
131 expansion in the here-documents used by config.status, as that
132 runs afoul of the Korn shell version M-12/28/93d bug described in
133 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
134 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
135 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
137 2006-05-23 Jim Meyering <jim@meyering.net>
139 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
140 Fix typo introduced with 2006-04-02 change. It reversed the sense
141 of the test.
143 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
145 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
146 ac_dB slightly, to save bytes in the script.
147 Max out at 50 lines, rather than 96; this is more likely
148 (though not guaranteed) to avoid obscure 'sed' failures.
150 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
152 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
153 `tr -d -' as bad option argument. Work around this by deleting
154 an unrelated character.
155 Report by Tim Rice <tim@multitalents.net>.
157 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
158 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
159 Stepan Kasal <kasal@ucw.cz>
161 * doc/autoconf.texi (Particular Programs): Do not promise that
162 we always prefer the GNU version of the program, and that we
163 search according to PATH; both rules can have exceptions.
164 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
165 AC_PROG_SED. Move descriptions of limitations
166 to the Limitations of Usual Tools section.
167 (Limitations of Usual Tools) <sed>: Mention script length
168 limitations with Solaris /usr/ucb/sed.
169 <grep>: Fix wording for empty alternative. Mention that -c and
170 -l should not be combined, and that -E and -F should not be
171 combined.
173 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
174 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
176 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
177 limits in Solaris 8 /usr/ucb/sed by testing a long script.
179 2006-05-22 Stepan Kasal <kasal@ucw.cz>
181 * doc/autoconf.texi (Defining Symbols): Literal parameter of
182 AC_DEFINE is now passed to m4_pattern_allow.
183 * NEWS: Mention that; likewise for AC_SUBST.
184 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
185 the parameter to m4_pattern_allow.
186 * tests/tools.at: Add a check for that.
188 2006-05-22 Stepan Kasal <kasal@ucw.cz>
190 * lib/autoconf/status.m4: Fix typos.
192 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
194 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
195 only the files that this macro generates.
197 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
199 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
200 the HP-UX sed limitation of 99 commands, labels do not count.
201 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
202 in the comment.
203 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
205 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
207 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
208 Import the following fix from coreutils:
210 2006-01-13 Jim Meyering <jim@meyering.net>
212 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
213 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
214 not double-quote uses of that variable, to accommodate the rare
215 case in which getmntent is available in none of the libraries
216 checked. This happens at least on FreeBSD 5.0.
218 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
220 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
221 ac_config_guess, ac_config_sub, and ac_configure, since evidently
222 some other programs unwisely rely on these undocumented vars.
223 But put in warning comments about them.
224 Problem reported by Ralf Wildenhues in
225 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
226 * NEWS: Document that these variables are intended to go away.
228 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
230 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
231 and set the language to C++ (analogous to the equivalent Fortran
232 tests).
234 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
235 * doc/autoconf.texi (C++ Compiler): Document it.
236 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
237 * NEWS: Update.
239 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
241 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
242 that caused config.status to generate 100-command sed scripts; the
243 portable limit is 99.
245 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
247 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
248 variable `ac_d' instead of `d' to avoid infringing namespace.
249 Report by Ralf Menzel.
251 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
253 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
254 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
255 * tests/tools.at (autoconf: subdirectories): New test, taken from
256 the corresponding problem report by Ralf Wildenhues in:
257 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
259 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
260 Quote some uses of shell variables if they might suffer unexpected
261 globbing. This doesn't fix all instances of quoting problems that
262 I found, just the easy ones that look safe.
263 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
264 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
265 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
266 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
267 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
268 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
269 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
270 Likewise.
271 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
272 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
274 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
276 * bin/autoreconf.in ($help): Reword according to the manual.
277 Suggested by Olly Betts.
279 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
280 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
282 * bin/autoreconf.in: Pass the directory argument to
283 `require_configure_ac'. Fix comment.
284 * tests/torture.at (Configuring subdirectories): Expose this.
285 Reported by Olly Betts.
287 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
289 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
290 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
291 Automake as follows:
293 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
294 `$configure_in' instead of `configure.in', to preserve
295 directory component.
297 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
299 * config/config.guess, config/config.sub, config/texinfo.tex,
300 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
302 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
304 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
305 test for C99 conformance; (bool) 0.5 is an integer constant
306 expression, but (bool) -0.5 is not. Problem reported by Fedor
307 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
309 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
311 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
312 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
313 Warn about obsolete install-sh files. Remove stray sentence
314 fragment and fix cross reference.
315 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
316 install -d; this undoes the 2006-05-10 change.
317 (MKDIR_P): Mark with AN_MAKEVAR.
318 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
319 that we don't require $INSTALL to be thread-safe. Move comments
320 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
321 of AC_PROG_INSTALL. Output a message saying that we're checking
322 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
323 MKDIR_P instead of AC_SUBST.
324 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
325 Special magic for MKDIR_P, too.
326 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
327 a dnl.
328 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
330 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
332 Sync from Automake, as follows:
334 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
335 * config/install-sh: Initialize IFS, so field splitting isn't
336 turned off later.
337 * config/mkinstalldirs: Likewise.
338 * config/missing: Remove superfluous quotes. Replace all uses of
339 `[' by `test', for consistency, and for..
340 * config/missing (sed_minuso, sed_output): New variables.
341 (autom4te, help2man, makeinfo): Use them. Unifies detection of
342 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
343 Fixes `missing' to detect `--output' for help2man. Fixes
344 PR automake/483. Report by Dennis J. Linse.
345 (autom4te): Document in `missing --help'.
347 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
349 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
350 * config/install-sh: Don't use 'path' to talk about file names,
351 as per GNU coding standards. Close a race condition reported by Ralf
352 Wildenhues and Stepan Kasal. There is still a race condition
353 on hosts that predate Posix 1003.1-1992, but we can't help this.
354 Don't mishandle weird characters like space on pre-Posix hosts.
355 Invoke mkdir at most once per dir arg on pre-Posix hosts.
356 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
357 AC_PROG_MKDIR_P from AS_MKDIR_P.
358 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
359 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
360 earlier editions are not (including Automake 1.8.3).
361 Do not suggest mkinstalldirs for thread-safety.
362 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
363 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
364 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
365 presence of special characters and race conditions.
366 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
367 in Autoconf's name space.
369 2006-05-10 Bruno Haible <bruno@clisp.org>
370 and Paul Eggert <eggert@cs.ucla.edu>
372 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
373 from Automake with minor changes.
374 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
376 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
378 * config/install-sh: Update to Automake CVS version, as follows:
379 2006-04-25 Stepan Kasal <kasal@ucw.cz>
380 * lib/install-sh: Simplify the expr implementation of dirname.
381 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
382 * lib/install-sh: Handle --, and diagnose unknown options.
384 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
386 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
387 `./autom4te' to create `./testsuite', since the `all' target
388 will ensure its presence, but `installcheck' should not create
389 the uninstalled wrappers.
391 * tests/torture.at (Unusual Automake input files): Skip if we
392 detect automake < 1.8.
394 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
396 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
397 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
398 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
399 * NEWS: Update.
401 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
403 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
404 munge (multiple) white space and other oddities.
405 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
406 single quotes in variable assignment.
407 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
408 and similar failures by adding multiple spaces, tabs, and other
409 special characters.
410 Report and different test suggested by Francesco Romani
411 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
413 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
414 single quotes, we only need to search for single quotes; this
415 both simplifies the search pattern, and makes us less
416 susceptible to `echo' variations for arguments not containing
417 single quotes.
418 (_AC_ARG_VAR_VALIDATE): Likewise.
420 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
422 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
423 `$*' and IFS concatenation issue with traditional shells and
424 bash-2.04. Report by Seanster@Seanster.com.
426 2006-05-03 Bruno Haible <bruno@clisp.org>
428 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
429 precisely which Mac OS X versions have the od problem.
431 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
433 * doc/autoconf.texi: Use @option systematically.
434 (Integer Overflow):
436 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
437 and Bruno Haible <bruno@clisp.org>
439 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
440 about 'od'.
441 (Integer Overflow): Mention the special case of integer division
442 overflow.
444 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
446 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
447 traditional shells like the Solaris one that do not use the
448 first IFS character for assembling `$*'.

503 2006-04-25 Stepan Kasal <kasal@ucw.cz>
505 * bin/autoconf.as (me): Replace by as_me.
507 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
509 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
510 since as_me isn't set yet.
512 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
514 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
515 a few minor bugs in this area.
517 * doc/autoconf.texi (Programming in M4sh): Comment out the
518 documentation of AS_BASENAME, for now.
519 (Shell Substitutions): Do not use AS_DIRNAME in an example.
520 (Limitations of Builtins) <basename>: Do not refer to
521 AS_BASENAME.

548 with more accuracy and detail.
550 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
552 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
553 Archive is not officially `GNU' any more. Update URL.
554 (Defining Directories): Likewise
555 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
557 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
559 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
560 newline from the `trap' code to finish `config.log'; the NetBSD
561 /bin/sh resets the exit status after an empty command, as
562 documented in doc/autoconf.texi.
563 Reported by Dalibor Topic <robilad@kaffe.org>.
565 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
567 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
568 Suggested by Bruno Haible.
570 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
572 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
573 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
574 Instead, just list the shells that we know work.
575 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
576 changed. Be more cautious about the _cv_ variable.
577 * tests/tools.at (Syntax of the shell scripts): Check the
578 _cv_ variable once, at first, to avoid an internal autoconf error
579 when sh -n does not work.
581 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
583 * lib/Autom4te/FileUtils.pm: Sync from Automake.
585 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
587 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
588 use ">&-" since we're only 99.999% sure that this is portable,
589 and since the MinGW bug is fixed in a different way.
590 * lib/autotest/general.m4 (AT_INIT): Likewise.
592 2006-04-16 Stepan Kasal <kasal@ucw.cz>
594 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
595 before opening config.log, to avoid hitting a bug on MinGW.
597 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
599 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
600 AS_MESSAGE_LOG_FD before reopening it onto the log file.
601 This works around a MinGW bug reported by Eric Paire.
602 Make sure that all writes to the log file append to it,
603 rather than possibly losing data.
604 * lib/autotest/general.m4 (AT_INIT): Likewise.
606 2006-04-14 Stepan Kasal <kasal@ucw.cz>
608 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
609 description.
611 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
613 * NEWS: Update.
615 * configure.ac (AC_INIT): Bump to 2.59d.
617 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
619 Version 2.59c.
621 * Makefile.maint (news-date-check): Do not require a leading `*'
622 before the release date in NEWS.
624 2006-04-12 Stepan Kasal <kasal@ucw.cz>
625 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
627 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
628 the instantiated file do not contain the string 'datarootdir'
629 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
630 @mandir@, replace the reference '${datarootdir}' by the value.
631 * tests/torture.at (datarootdir workaround): New test.
632 * NEWS: Advertise this temporary fixup.
633 Based on a patch by Bruno Haible, reported and analyzed by
634 Paul Eggert and Noah Misch.
636 2006-04-12 Eric Blake <ebb9@byu.net>
638 * tests/autotest.at (Debugging a failed test): Fix comment.
640 2006-04-12 Stepan Kasal <kasal@ucw.cz>
642 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
643 all the changes since 2006-04-07.
645 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
647 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
648 succeeded, but `ln -s file dir' failed, take care to remove the
649 leftover target before the next test, to prevent its spurious
650 failure; also make sure `ln file dir' works before selecting it.
651 Thanks to Keith Marshall for pointing this out.
652 * THANKS: Update.
654 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
655 assignments in `at_debug_args', so that we put them correctly
656 in the `run' script.
657 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
658 Reported by Eric Blake.
660 2006-04-11 Eric Blake <ebb9@byu.net>
662 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
663 top-level tests after micro-suite has been run. Used in...
664 (Debugging a successful test, Debugging script and environment),
665 (Debugging a failed test): ...these new tests. The first of these
666 is fixed by...
667 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
668 macro, split out from...
669 (AT_INIT): ...here, so that using -d also generates a run script.
670 Document that -d inhibits top-level logging.
671 * doc/autoconf.texi (testsuite Invocation): Document that -d only
672 inhibits top-level logging; debug scripts are created.
674 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
675 check.
676 * tests/autotest.at (Empty test, Empty check): New test to check it.
678 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
679 from gcc.
681 2006-04-10 Stepan Kasal <kasal@ucw.cz>
683 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
684 the files if a problem appears. Make the empty *.at files
685 read-only, too. Proposed by Ralf Wildenhues.
687 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
689 * config/Makefile.am: Add comment to force updated Makefile.in.
691 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
692 space only patch to this file, this patch causes the Makefile.in
693 files that include freeze.mk to be updated, and thus have a
694 newer time stamp again, which in turn makes a pristine CVS
695 checkout have correct time stamps.
697 * Makefile.maint (cvs-sv): New macro, to be used..
698 (config.guess-url_prefix, config.sub-url_prefix)
699 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
700 point to CVS text checkout of Gnulib files.
701 (copyright-check): Bump current year.
702 (announcement): Do not hard-wire `./announce-gen'.
703 (cvs-update): Propagate failures of `cvs' and `move-if-change'
704 correctly.
705 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
706 `chmod +x'.
707 (wget_files): Update config.guess, config.sub, texinfo.tex by
708 `wget-update', now that their URLs work again.
710 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
712 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
713 Problem noted by Paul D. Smith.
715 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
717 * doc/autoconf.texi: Remove unused words from word list.
718 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
719 .x-sc_trailing_space: New files.
721 * doc/standards.texi: Sync from gnulib.
723 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
724 `LIBOBJDIR' as experimental.
726 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
727 with a target directory; it's internally implemented as `cp'
728 anyway, but since Autoconf advertises the possibility to use
729 a target directory when LN_S is `ln -s', we need to find out.
730 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
731 analyzed by Keith Marshall <keith.marshall@total.com>.
733 * THANKS: Update.
735 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
737 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
738 confdefs.h as-is. In general, if it has backslash-newline or the
739 like, then it doesn't work either to sort or to remove empty
740 lines.
742 2006-04-09 Stepan Kasal <kasal@ucw.cz>
744 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
746 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
748 * lib/autom4te.in (Automake-preselections): Preselect
749 _AM_SUBST_NOTMAKE.
751 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
753 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
754 apostrophe within a single-quoted string, as this is the usual
755 tradition and is easier to read than '"'"'. Don't rely on the
756 shell treating "$/" like '$/'. Use a more-consistent indenting
757 style for the trap.
759 2006-04-09 Eric Blake <ebb9@byu.net>
761 * tests/autotest.at (Backquote command substitution),
762 (Multiline backquote command substitution): Remove mistaken
763 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
764 applied...
765 (Parenthetical command substitution, Multiline parenthetical
766 command substitution): here.
768 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
770 Import macros from gnulib (often changing their name).
772 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

786 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
787 Gnulib section.
788 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
789 suggest a #define rather than a typedef for _Bool, and mention
790 Gnulib rather than trying to substitute stdbool code.
791 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
792 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
793 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

796 headers too.
797 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
798 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
799 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
800 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
801 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
802 (C Compiler): Move AC_C_LONG_DOUBLE to ...
803 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
804 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
805 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
806 (Coding Style). Don't mention m4_expand_once.
807 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

817 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
818 Catch a bug in an HP-UX C compiler.
819 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
820 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
821 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
822 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
823 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):

825 New macros.
827 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
828 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
830 2006-04-08 Stepan Kasal <kasal@ucw.cz>
832 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
833 of the warning introduced by the 2001-08-28 change.
835 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
836 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
838 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
839 variables shall be overriden by the cache.

843 2006-04-07 Stepan Kasal <kasal@ucw.cz>
845 Revert the patch from 2006-04-01 and only improve
846 _AS_DETECT_BETTER_SHELL:
848 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
849 skip nonexistent directories.
850 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
851 only shell candidates which exist.
852 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
853 * lib/autotest/general.m4 (AT_INIT): No need to give three
854 parameters to _AS_PATH_WALK.
856 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
857 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
859 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
860 distinguish m4sugar macros.
861 * tests/tools.at (autoupdating with aclocal and m4_include):
862 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
863 test case by Noah Misch <noah@cs.caltech.edu>.
865 2006-04-07 Stepan Kasal <kasal@ucw.cz>
867 Revert my change from 2006-03-17, in other words:
868 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
869 and DUALCASE=1.
870 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
871 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
872 it is set.
874 2006-04-07 Eric Blake <ebb9@byu.net>
876 * doc/autoconf.texi (Programming in M4sh): Document that
877 AS_MKDIR_P exits the script on failure.
878 * lib/autotest/general.m4: Remove redundant AS_ERROR.
880 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
882 * config/elisp-comp, config/install-sh, config/mdate-sh,
883 config/missing, config/mkinstalldirs: Sync from Automake.
885 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
886 from Automake.
888 * doc/make-stds.texi: Sync from gnulib.
890 2006-04-06 Eric Blake <ebb9@byu.net>
892 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
893 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

897 Eric Blake <ebb9@byu.net>,
898 Paul Eggert <eggert@cs.ucla.edu>,
899 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
901 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
902 whether `set' quotes correctly: redirect stderr of the tested
903 `set', and use a subshell, for Ultrix; use `sed' instead of
904 `grep' for zsh `set' which may write binary output; match only
905 at the beginning of a line, to avoid false positives.
906 In order to avoid false positives by unrelated variables with
907 multiline content, put the dump algorithm in a subshell and
908 unset all variables containing newlines (except some which are
909 special to the shell). Warn about cache variables that are
910 unset.
912 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
914 * config/config.guess, config/config.sub, config/texinfo.tex:

970 for --help from Cygnus `configure.'
972 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

1116 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1117 initial `rm' of the candidate files...
1118 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1119 the same list in subsequent `rm' calls, and for the temporary

1122 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1123 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1124 no longer needed) by libtool. Make it a cache check.
1125 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1126 copied here by mistake.
1127 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1128 _AC_COMPILER_EXEEXT.

1165 subordinate tools.
1166 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
1167 * doc/autoconf.texi (autoreconf Invocation): Document it.
1169 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

1835 `tmp' to avoid file removal race.
1837 2005-11-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1839 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
1840 ac_clean_files and LIBOBJS.
1842 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1844 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
1845 Factor functionality to..
1846 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
1847 `AC_SUBST($1)' in the public version.
1848 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
1849 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
1850 ac_pt_* variables.
1852 2005-11-01 Stepan Kasal <kasal@ucw.cz>
1854 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
1855 filesystems.
1857 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1859 * NEWS: Move AH_HEADER mention to right place.
1861 2005-10-27 Stepan Kasal <kasal@ucw.cz>
1863 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
1864 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
1866 2005-10-25 Stepan Kasal <kasal@ucw.cz>
1868 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
1869 conftst2.$ac_objext.
1870 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
1872 2005-10-24 Stepan Kasal <kasal@ucw.cz>
1874 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
1875 conftest.o, to see whether the compiler really obeys; rm the object
1876 file before and after the test and register it with ac_clean_files.
1877 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
1879 2005-10-21 Stepan Kasal <kasal@ucw.cz>
1881 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
1882 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
1883 code so that the most common case requires less forks.
1885 2005-10-20 Stepan Kasal <kasal@ucw.cz>
1887 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
1888 not portable; thanks to Paul Eggert and Alexandre.
1890 * NEWS: Fix an old typo.
1892 2005-10-20 Jim Meyering <jim@meyering.net>
1894 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
1895 the latter'', in two places.
1897 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
1899 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
1900 AC_LANG_PROGRAM, fixing a typo. Don't give details about
1901 the inner workings of AC_LANG_FUNC_LINK_TRY.
1902 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
1903 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
1904 by the function rather than ignoring it.
1905 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
1906 comparing its address. Intel's interprocedural optimization was
1907 outsmarting the old heuristic. Problem reported by
1908 Mikulas Patocka.
1910 2005-10-19 Stepan Kasal <kasal@ucw.cz>
1912 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
1914 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
1916 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

1919 2005-10-04 Stepan Kasal <kasal@ucw.cz>
1921 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
1922 before removing it (chmod -R u+rwx); there are three instances of this.
1924 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1925 Stepan Kasal <kasal@ucw.cz>
1927 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
1928 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
1929 make its content writable before removing it. Remove an errorneous
1930 comment from the end, where the logs of the failed tests are copied
1931 to the main log file.
1933 2005-09-27 Stepan Kasal <kasal@ucw.cz>
1935 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
1936 in case the computer is too quick. Double quote the configure.ac
1937 snippets.
1939 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
1940 problems if the testsuite were running too fast.
1942 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1944 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1945 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1946 (which belong to Xt, not X itself). See Debian bug 327655.
1947 * NEWS: Mention this.
1949 2005-09-07 Stepan Kasal <kasal@ucw.cz>
1951 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
1953 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
1955 * config/move-if-change: Don't output "$2 is unchanged";
1956 suggested by Ben Elliston. Handle weird characters correctly.
1958 2005-09-06 Stepan Kasal <kasal@ucw.cz>
1960 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
1961 calls, so that the final expansion of this macro is shorter.
1962 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
1963 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
1964 the cleanup there. Use AS_VAR_* macros, to be more general.
1965 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
1967 * lib/autoconf/general.m4: Use AS_IF where appropriate.
1969 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
1971 2005-09-01 Stepan Kasal <kasal@ucw.cz>
1973 * doc/autoconf.texi (Configuration Headers): Add an index entry
1974 for AH_HEADER.
1976 2005-08-26 Pavel Roskin <proski@gnu.org>
1978 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
1979 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
1980 running xmkmf.
1982 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
1984 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
1985 The previous patch didn't work, so try a better one.
1987 2005-08-26 Stepan Kasal <kasal@ucw.cz>
1989 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
1990 in the example. Reported by Bruno Haible.
1991 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
1992 "if $undefined_var;" succeeds with my shell.
1994 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
1995 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
1996 but change the m4_divert_text to m4_divert_once.
1998 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2000 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2001 Work around bug in Solaris /usr/xpg4/bin/awk.
2002 The bug is present in at least Solaris 8 through 10.
2004 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2006 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2007 some evil values and relying on the fact that $* concatenates the
2008 parameters by the first character from IFS.
2010 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2011 Stepan Kasal <kasal@ucw.cz>
2013 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2014 first header appears, define AH_HEADER.
2015 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2016 Update limitations about when to call AC_CONFIG_HEADERS.
2017 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2018 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2019 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2020 ``Configuration Actions''; fix their index entries.
2022 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2023 options correctly. Process N-M as M-N if M is smaller than N.
2024 Process ranges correctly so that N-N will run only N.
2025 Sort and uniquify the tests that will be run. If there is more
2026 than one test, reinsert the banners for the tests.
2027 * tests/autotest.at (Keywords): Unmark XFAIL.
2029 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2031 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2032 before passing the macro name to AH_TEMPLATE.
2034 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2035 now opens log after option processing; in particular, --version
2036 and --help do not touch config.log.
2038 * Makefile.maint: Revert the change from 2005-08-12.
2040 2005-08-22 Stepan Kasal <kasal@ucw.cz>
2042 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
2043 common code to...

2046 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2048 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2049 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2050 Language cleanup.
2052 * doc/autoconf.texi (Defining Symbols, Changed Results):
2053 Prepend to LIBS, not append, in examples.
2055 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2057 When building in place, set srcdir="."; suggested by Tim Van Holder.
2059 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2060 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2061 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2062 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2063 does not mean "no --srcdir option".
2065 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2067 * tests/autoscan.at (autoscan): New file.
2068 * tests/suite.at: Use it.
2069 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
2070 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2072 * tests/autotest.at (Keywords): Test keywords combinations.
2074 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2076 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2077 add "2>&1"; gzip 1.2.4 prints help on stderr.
2079 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2081 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2082 was pushdef'ed twice while popped only once. Push it only once.
2083 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2085 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2087 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
2088 prefixed by mere "===", not "configure: === ".
2090 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
2092 * Makefile.maint: Update from Bison.
2094 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2095 "<tab>" in comment, so that the point is understandable.
2097 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2099 Rewrite substantial part of lib/autoconf/status.m4.
2100 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2101 and CONFIG_COMMANDS are not processed in four separate loops.
2102 Instead, there is one main loop. This alows that the common code
2103 is expanded only once, thus config.status (and configure) is smaller.
2105 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2106 the AC_LIST_FILES and cousins macros are no longer used.
2108 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2109 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2110 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2111 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2112 contain the initialization, nor the for loop, nor the associated
2113 commands; all these go to ...
2114 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2115 _AC_OUTPUT_CONFIG_STATUS.
2116 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2117 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2118 (_AC_OUTPUT_FILE): The creation of the sed script ...
2119 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2120 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2121 _AC_OUTPUT_MAIN_LOOP.
2122 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2123 _AC_CONFIG_COMMANDS): Use ...
2124 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2125 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2126 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2127 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2128 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2129 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2130 ... new macros.
2131 (_AC_CONFIG_UNIQUE): Update.
2132 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2133 Replaced by this ...
2134 (_AC_LIST_TAGS): ... new common macro.
2135 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2136 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2137 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2138 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2139 this didn't belong to the `config commands' section.
2140 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2141 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2142 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2143 to the `config commands' section either.
2144 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2145 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2147 ... and many changes to the comments nearby.
2149 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2150 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2151 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2152 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2153 (#define header templates): The comment at the top of the generated
2154 header now includes the name(s) of the source file(s).
2156 Several unrelated small changes:
2158 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2159 parameter to AC_DIAGNOSE.
2160 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2161 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2162 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2163 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2164 with AU::AC_OUTPUT.
2165 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2166 in AC_OUTPUT doesn't double-quote it either.
2167 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2168 parameters.
2170 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2172 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2173 versions of Portland Group compiler produce single- and double-quoted
2174 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2175 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2177 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2179 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2180 This is a corrected version of yesterday's patch.
2182 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2184 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2185 path, too; insert a "===" to emphasize the line.
2187 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2188 ac_cv_build_alias to ac_build_alias.
2189 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2191 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2192 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2193 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2194 (AC_ARG_VAR): ... here.
2195 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2196 target_alias.
2198 Keep a list of all precious variables and process them with one simple
2199 for loop, instead of expanding all commands, or, OTOH, complicated
2200 processing of output of "set".
2201 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2202 variable names in new macro...
2203 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2204 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2205 a loop to assign all ac_env_* and ac_cv_env_* variables.
2206 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2207 to INIT_PREPARE.
2208 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2209 its value to shell variable ac_precious_vars and call
2210 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2211 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2212 _AC_ARG_VAR_VALIDATE.
2214 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2215 and the AC_SUBSTs ...
2216 (AC_INIT): ... here.
2218 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2219 the ac_subst_files section in config.log.
2221 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
2223 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

2228 * tests/c.at (C keywords): Test AC_C_TYPEOF.
2230 Fix problems reported by Nicolas Joly.
2231 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
2232 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2233 They are generated by the Tru64 v5.1B shell.
2235 2005-07-05 Stepan Kasal <kasal@ucw.cz>
2237 Fix my changes from 2005-07-01; reported by Noah Misch.
2238 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2239 description, the macro now accepts only a single tag.
2240 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
2242 Fix cases when the varsions of Autoconf and Autotest don't match.
2243 Reported by Noah Misch.
2244 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
2245 at_top_builddir, for compatibility with older autotest.
2246 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2247 is not set, use at_top_builddir, for compatibility with older
2248 versions of autoconf.
2250 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2252 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2253 Problem reported by Patrick Welche.
2255 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2257 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2258 sed substitution command, so that we allow | in program prefixes
2259 and program suffixes. (& is a problem anyway; we're not fixing
2260 that here.)
2261 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2262 configure_input, top_builddir, srcdir, etc.
2263 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2264 PATH_SEPARATOR in AUTOTEST_PATH.
2266 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2268 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
2269 for loop over config.site files using `set', to allow
2270 directory names containing IFS characters.
2272 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
2274 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2275 directories with weird names. Apparently some people like living
2276 on the edge. However, improve the test that "pwd" actually does
2277 report a name for the working directory.
2278 * NEWS: Remove the claim that we test for funny chars in dir names.
2280 2005-07-01 Stepan Kasal <kasal@ucw.cz>
2282 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
2283 replaced ...

2292 about #include <config.h>.
2293 (Generic Functions): Mention the Gnulib project.
2294 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
2296 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2297 document to output the default config_* lists to config.status.
2298 Don't recognize option --file, if the functionality is not there.
2299 Likewise for --header; moreover, recognize --he and --h as shortcuts
2300 for --help in that case.
2302 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2303 matches the order of execution. No code changed.

2326 (AC_SUBST): Call it.
2327 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2328 the directory specific variables; but don't call it for configure_input.
2330 2005-06-28 Derek Price <derek@ximbiot.com>
2332 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2333 addition.
2335 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2337 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2338 directory have inherent problems with special characters like spaces,
2339 due to limitations in Make syntax. Problem reported by Alexandre
2340 Duret-Lutz.
2341 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
2342 Also, fix Tru64 porting problem with shell patterns,

2354 from Justace Clutter.
2355 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
2356 variable into diagnostic. Make the diagnostic an error, not a warning,
2357 because we really don't support spaces and suchlike in dir names.
2358 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2359 Don't worry about backslashes in srcdir; it can't happen now.
2360 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
2361 Simplify ac_optarg handling.
2362 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

2382 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
2384 2005-06-21 Stepan Kasal <kasal@ucw.cz>
2386 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
2387 b, t, r, w commands require single space, while : cannot have any.
2388 (Special Shell Variables): Fix sed code this in the example.
2389 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2390 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2392 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2393 expand to the empty list. Don't use two pairs of m4_changequote,
2394 it's not necessary.
2396 2005-06-20 Derek Price <derek@ximbiot.com>
2398 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
2400 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
2402 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2403 * doc/autoconf.texi:
2404 Don't mention Solaris versions so much, if a
2405 problem is common to all extant versions of Solaris. Say "SunOS
2406 4" instead of "SunOS" for SunOS 4.
2407 (awk): Mention more of the limitations of traditional Awk.
2408 (cat): Don't talk about cat -v.
2410 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
2412 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
2413 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

2415 to be compatible with glibc strverscmp.
2416 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
2418 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
2419 on Mac OS X 10.4 reported by Peter O'Gorman in:
2420 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
2421 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
2422 Use shell builtins rather than 'expr', to work around expr bug.
2424 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
2426 * doc/autoconf.texi: "filesystem" -> "file system".
2427 "behaviour" -> "behavior".

2429 * lib/autoconf/general.m4: Omit blank after ":" sed command,
2430 as per POSIX.
2431 * lib/m4sugar/m4sh.m4: Likewise.
2432 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
2433 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
2435 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
2436 (.x.1): Ignore the time stamp in the .TH line when deciding whether
2437 to update the man page. That way, we don't have to check in new
2438 man pages every month.
2440 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
2441 quotes and backslashes. Patch from Derek Price.

2446 AS_TR_SH.
2448 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
2450 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2451 -u, since it outputs chatter if the input files are the same.
2452 Problem reported by Ralf Menzel.
2454 2005-06-08 Derek Price <derek@ximbiot.com>
2456 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2457 renaming them since they are about to be redefined anyhow.
2459 2005-06-08 Derek Price <derek@ximbiot.com>
2461 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2462 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2463 Move m4_undefine to alphabetical order.
2465 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
2467 * README: Recommend GNU M4 1.4.3 or later.
2468 * doc/autoconf.texi (Introduction): Likewise.
2469 Reword to avoid some formatting glitches.
2470 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
2471 Clarify explanation of HP compiler bug.
2472 Redo example output tp match current CVS snapshot.
2473 Use @example.org in email addresses when the examples
2474 might get inadvertently cut-and-pasted into user code.
2475 Remove example of autom4te usage that doesn't seem to work now.
2476 Use modern AC_INIT (except when the example is meant to be
2477 shown with Autoconf 2.13).
2478 Update ksh info for Solaris 9 and later.
2479 KB -> kB.
2480 Modernize description of Automake versions a bit.
2481 Don't claim a future version of Autoconf is near.
2482 * doc/install.texi: Reword to avoid some formatting glitches.
2484 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2486 * doc/autoconf.texi: Add [] to examples, so that the manual
2487 follows its own advice about quoting better.
2488 Reword to avoid some formatting glitches.
2489 * doc/installt.exi: Reword to avoid some formatting glitches.
2491 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2492 Tru64 ksh pattern matching bug. Reported against Libtool by
2493 Albert Chin <libtool@mlists.thewrittenword.com> and
2494 Nicolas Joly <njoly@pasteur.fr>.
2496 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2498 m4_cdr of one-member list was [[]] (one-member list containing an
2499 empty string) instead of [] (an empty list. Callers were skewed to
2500 match this misbehaviour. As a consequence of this:
2501 - m4_foreach([x], [], [foo]) expanded to `foo', while
2502 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2503 This bug has been fixed:
2505 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2506 expand to an empty string; print error msg if called without
2507 an argument list.
2508 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2509 misbehaviour; handle [] and [[]] correctly.
2511 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2513 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

2515 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
2517 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
2519 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2520 swallow records with more than 99 fields.
2521 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2522 parse the long line.
2524 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2526 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2527 swallow literals longer than 399. Reported by Ralf Wildenhues.
2528 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
2529 to workaround this limitation.
2531 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
2533 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
2534 to gfortran, and make these the first two compiler names
2535 checked (following the general autoconf preference for gcc).
2537 2005-06-03 Stepan Kasal <kasal@ucw.cz>
2539 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
2540 (DISTCLEANFILES): Remove $(check_SCRIPTS).
2541 (testsuite): Make sure autotest.m4f is up-to-date before using it.
2543 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
2545 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
2546 expression of unbounded size when processing the --list
2547 option. This runs afoul of a limit of 399 bytes per regular
2548 expression on AIX. Problem reported by Ralf Wildenhues.
2550 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

2553 * doc/autoconf.texi (Particular Headers): Reword example
2554 for multiline stdbool replacement.
2555 (Setting Output Variables): Reword text a bit. Don't
2556 give all the details about |#_!!_#|.
2557 Reword description of line replacement.
2559 2005-05-31 Dan Manthey <dan_manthey@partech.com>
2561 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2562 now contain newlines, and substituted files must be referenced on
2563 a line alone; the sed scripts to substitute them are now very
2564 different.
2565 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
2566 commands can be put in a sed script portably.
2567 * doc/autoconf.texi (Setting Output Variables): Document above
2568 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
2569 use of multiline substitution.

2579 * tests/local.at: Don't attempt to check for negated character
2580 classes in shell scripts. The test was too brittle.
2582 2005-05-25 Stepan Kasal <kasal@ucw.cz>
2584 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
2585 * doc/autoconf.texi (Limitations of Builtins): Document this
2586 limitation.
2588 2005-05-24 Stepan Kasal <kasal@ucw.cz>
2590 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
2591 common code; used in many places in the tree.

2593 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
2595 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
2597 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
2598 messages when ac_unique_file is not found.
2599 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
2600 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
2601 commands, for consistency with AC_MSG_ERROR and such.
2603 * bin/autoconf.as: Make more use of "shift 2" in option processing.
2605 * bin/Makefile.am: Merge the two rules for creating scripts.

2613 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2615 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
2616 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
2617 (ac_top_builddir): ... this ...
2618 (ac_top_build_prefix): ... to this; the old name is also kept, for
2619 backward compatibility.
2620 (ac_top_builddir_sub): New variable, without the trailing slash,
2621 always nonempty.
2622 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
2623 * doc/autoconf.texi (Configuration Actions): Rename
2624 ac_top_builddir to ac_top_build_prefix.
2625 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

2634 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2636 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2637 argument to m4_foreach. I guess it was necessary in the past,
2638 but I think it's a no-op now.
2640 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2642 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2643 ``cat <<_ACEOF'' commands to one.
2644 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
2645 * lib/autoconf/status.m4: On various places, use expr instead of
2646 ``echo|sed.''
2647 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
2648 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2649 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2650 a range.
2651 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2652 the wrong patterns between ``case'' and ``esac.'' The previous
2653 code had false positives.
2655 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
2657 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
2658 as on 2005-05-02.
2659 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

2721 * doc/autoconf.texi (Autoconf Language): Be more precise about
2722 quoting rules. Problems noted by Stepan Kasal.
2723 Also, throughout this document, be more careful about white space.
2724 "blank", "white space", and "space" all have different meanings
2725 and we should be careful to say what we mean.
2727 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

2745 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
2746 set by latest automake.
2748 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2750 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
2751 outputs 0 on GNU/Linux these days.
2753 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
2755 * doc/autoconf.texi (Autoconf Language): Add more description
2756 about quoting heuristics.
2757 (Limitations of Builtins): Describe "set -" problems.
2759 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2761 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
2762 not newline.
2764 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
2765 by AC_DEFINE; it was a mistake.
2766 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
2768 2005-04-25 Stepan Kasal <kasal@ucw.cz>
2770 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
2772 2005-04-22 Stepan Kasal <kasal@ucw.cz>
2774 * doc/autoconf.texi (External Software): Quadrigraphs are not
2775 processed correctly in AS_HELP_STRING; avoid this in the examples.
2776 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
2777 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
2778 comment and reduce m4_default([foo], []) to [foo].
2779 (m4_strip): Update the explanation.
2781 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
2783 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
2784 Remove core.conftest.* too; it's generated by Tru64 5.1.
2785 Problem reported by Jennis Pruett.
2786 * lib/autoconf/functions.m4
2787 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2788 Don't bother to remove core files; AC_RUN_IFELSE should do that
2789 for you.
2791 2005-04-19 Stepan Kasal <kasal@ucw.cz>
2793 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

2810 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2812 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
2813 as well as configure.in. Problem reported by Gregorio Guidi.
2815 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
2817 * doc/autoconf.texi (Particular Functions): Use gnulib's current

2833 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2835 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
2836 Merge `-z option' as well for the benefit of Solaris link flags. Pass
2837 whole-archive (-zallextract, -zdefaultextract) options in the hope of
2838 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
2839 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
2841 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
2843 * NEWS: The configure command now warns you if you attempt to use
2844 a directory whose name contains a special character like space,
2845 newline, or "\".
2846 * doc/autoconf.texi (Installation Directory Variables): Allow
2847 "," in file names. Do not use \@; it's not a portable regexp.
2848 * bin/Makefile.am (edit): Likewise.
2849 * lib/Makefile.am (edit): Likewise.
2850 * tests/Makefile.am (edit): Likewise.
2851 * tests/semantics.at: Likewise.
2852 * tests/torture.at: Likewise.
2853 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
2854 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
2855 * doc/autoconf.texi (File System Conventions): Warn about
2856 unportable file names.
2857 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
2858 (AC_INIT): Use it.
2859 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
2860 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
2861 ac_pwd, and quote srcdir.
2862 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
2864 * doc/autoconf.texi: Fix some systematic formatting problems.
2865 ".)" needs a following @: if not at the end of a sentence, and
2866 similarly for "!)". "etc." should be preceded by a comma.
2867 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
2869 2005-03-22 Bruno Haible <bruno@clisp.org>
2871 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
2872 argument is often called 'build-aux'.
2874 2005-03-07 Stepan Kasal <kasal@ucw.cz>
2876 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
2877 macro AC_TRY_LINK is obsolete.
2878 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
2879 `AC_CONFIG_FILES'.
2881 2005-02-24 Stepan Kasal <kasal@ucw.cz>
2883 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
2884 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
2885 from a Common Lisp's `cl'.
2886 (AC_PROG_CXX): Behave according to the documentation: don't
2887 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
2888 make the variable CCC precious; use `cl.exe', not `cl'.
2890 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2891 Alexandre Duret-Lutz <adl@gnu.org>
2893 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
2894 /dev/null, as "configure" shouldn't read stdin, and this insulates
2895 us from problems (e.g., when testing for "cl"). Also, do this
2896 redirection before invoking "hostname" or "uname", and keep the
2897 original input stream available via...
2898 (AS_ORIGINAL_STDIN_FD): ... this new macro.
2899 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
2900 bother with "</dev/null" since it's now done at the top of
2901 'configure'.
2902 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
2903 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2904 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

2907 * tests/base.at (Input/Output): New test.
2909 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2911 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
2912 newline if neither \c nor -n work, as that would output two
2913 newlines. Prefer -n to \c. Reported by Stepan Kasal.
2915 2005-02-12 Stepan Kasal <kasal@ucw.cz>
2917 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
2918 This causes that any required macros inside will get before the if.
2919 * doc/autoconf.texi (autom4te.cache): A typo.
2921 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
2923 Undo previous change, except keep the change to
2924 lib/autoconf/programs.m4 that replaced grep with shell
2925 pattern-matching. This is because net-snmp configure reads stdin.
2926 Reported by Noah Misch.
2928 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
2930 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
2931 from /dev/null, as "configure" shouldn't read stdin, and this
2932 insulates us from problems (e.g., when testing for "cl").
2933 Suggested by Alexandre Duret-Lutz. Also, do this redirection
2934 before invoking "hostname" or "uname".
2935 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2936 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
2937 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
2938 "</dev/null" since it's now done at the top of 'configure'.
2939 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2940 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2941 Also, replace grep with shell pattern-matching, to save a process.
2943 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
2945 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2946 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
2947 avoid thinking that Allegro Common Lisp's "cl" command is a C++
2948 compiler.
2950 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
2952 * doc/autoconf.texi (Limitations of Usual Tools): Document that
2953 grep -q isn't portable. Improve grep -s explanation.
2954 Problem reported by Dan Manthey.
2956 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
2958 * doc/autoconf.texi (Special Shell Variables): Clarify
2959 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
2961 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2963 * doc/autoconf.texi: Use @acronym for DJGPP.
2964 Fix some @code's that should have been @env's, and vice versa.
2965 Sort environment variable names.
2966 Mention that shells no longer inherit IFS.
2967 Don't recommend PATH_SEPARATOR=';' so strongly.
2968 Mention that $RANDOM might expand to the empty string.
2969 "symlink" and "soft link" -> "symbolic link".
2970 Improve mktemp description (reported by Bruno Haible).
2972 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
2974 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
2975 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
2976 Likewise.
2977 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
2978 Likewise.
2980 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
2982 * NEWS: Mention AT_COPYRIGHT.
2984 * tests/local.at (AT_CMP): Use diff directly on input files rather
2985 than copying them.
2987 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
2988 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
2990 2005-02-04 Noah Misch <noah@cs.caltech.edu>
2991 and Paul Eggert <eggert@cs.ucla.edu>
2993 * tests/autotest.at (Empty test suite): New test.
2994 * tests/torture.at (Substitute and define special characters)
2995 (Substitute a 2000-byte string, Define to a 2000-byte string)
2996 (Substitute a newline, Define a newline): New tests.
2998 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3000 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3001 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3002 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3003 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3004 (Standard regular expressions): New test.
3005 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3006 excess test name quoting.
3007 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3008 CPPFLAGS to `configure' instead of setting it in `configure'.
3010 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3011 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3012 on some platforms.
3014 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3015 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
3017 * tests/local.at (AT_CMP): New macro.
3018 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
3019 (AC_SAVE_STATE): Move environment grep...
3020 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
3021 (AT_CONFIG_CMP): New macro.
3022 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
3023 * tests/c.at (Extensions): Do not exit early.
3024 * tests/atlocal.in: Inherit $GREP.
3026 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
3027 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
3029 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
3030 (AC_COPYRIGHT): Factor header comment portion out and move into...
3031 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
3032 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
3033 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
3034 --version output.
3035 * tests/local.at: Add Autoconf test suite copyright notice.

3041 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
3043 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3045 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3046 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3048 Try not to generated lines of unlimited length, as POSIX places a
3049 2047-byte limit on line length of portable text files.
3050 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3051 Use newline as a separator, not space.
3052 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
3053 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
3054 space.
3056 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3058 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
3059 as_func_*. Add test to check whether positional parameters
3060 are restored after function return.
3062 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
3064 * doc/autoconf.texi (Special Shell Variables): Mention _,
3065 BIN_SH, DUALCASE. Say that variables other than "status" are safe
3066 if they contain a lower-case letter. The DUALCASE problem was
3067 reported by Ralf Wildenhues.
3069 * bin/autoconf.as: Don't exit with status 0 after write failure
3070 with --help or --version.
3071 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
3072 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
3074 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3076 * doc/autoconf.texi (Limitations of Usual Tools):
3077 Unicos 9 sed limitations.
3078 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
3079 to get the option-enhanced interface on older Crays. Try ftn for
3080 Fortran 95 (newer Crays).
3082 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
3084 * man/Makefile.am (.x.1): Go back to the simple solution, but take
3085 care to echo the commands, so the user knows what's going on.
3086 Modified from a suggestion by Stepan Kasal.
3088 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
3089 with a cross reference. Derived from a suggestion by Bruce Korb.
3091 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
3093 * doc/autoconf.texi (config.status Invocation): Warn about
3094 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
3095 * doc/install.texi (Defining Variables): Likewise.
3096 Based on a proposed patch by Ralf Wildenhues.
3098 * man/Makefile.am (.x.1): Make sure the required generated files
3099 are up to date. Problem and original solution proposed by Stepan Kasal.
3100 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
3101 implicit-man-prerequisites): New rules, used by the above.
3103 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.
3104 * config/config.guess, config/config.sub, config/install-sh: Likewise.
3105 * config/missing, config/texinfo.tex: Likewise.
3107 2005-01-29 Stepan Kasal <kasal@ucw.cz>
3109 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3110 Update the long comment explaining it.
3112 m4_require no longer writes an ``is required by'' line to the
3113 execution stack. It contains only one bit of non-redundant
3114 information: that the macro was required, not called. And even
3115 this bit is useless in most situations: have you ever met a macro
3116 which both calls and requires the same macro?
3118 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3119 (_m4_defun_pro_outer): ... only via this macro, for the outermost
3120 macro.
3121 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
3122 (m4_expansion_stack_pop): Remove the misplaced comment.
3123 (m4_require): Don't put the ``is required by'' line to the
3124 execution stack; slightly improve the out-of-a-defun error message.
3125 (_m4_divert_grow): New macro, counter for the temporary diversions.
3126 (_m4_require_call): Use it.
3127 * tests/m4sugar.at (m4_require): Expect output without the
3128 ``is required by'' messages.
3130 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3132 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3133 rather than x for expr.
3135 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3136 this is safe.
3137 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
3138 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3139 * lib/autotest/general.m4 (AT_INIT): Likewise.
3140 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Likewise.
3141 * tests/mktests.sh: Likewise.
3143 2005-01-27 Akim Demaille <akim@epita.fr>
3145 Have autoheader honor --force.
3147 * doc/make-stds.texi, doc/standards.texi: Update from masters.
3148 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
3149 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
3150 from masters, so that FileUtils.pm's update_file provide --force
3151 support.
3152 * bin/autoheader.in: Pass $force to update_file so that
3153 config.h.in is always recreated when --force.
3155 2005-01-24 Stepan Kasal <kasal@ucw.cz>
3157 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
3159 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3161 * doc/autoconf.texi (Limitations of Builtins): Clarify that
3162 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
3164 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3166 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3167 Warn about newline stripping in `` and $(). Update Solaris
3168 version to 9.
3169 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3170 X insulates us from future changes to Posix.
3171 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3172 stripping.
3174 2005-01-19 Stepan Kasal <kasal@ucw.cz>
3176 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
3177 you cannot use AC_DEFINE to define macros containing `[' or `]'.

3538 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
3539 "char c = '\200';" rather than "char c = 0x80;" as the

3644 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
3645 Problem reported by Stepan Kasal.
3647 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
3649 Fix problems reported by Andreas Buening in:
3650 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
3651 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
3652 in test makefile.
3653 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
3654 readable; it's not true in OS/2-emx.
3656 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
3658 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
3659 "/usr/include", clear ac_x_includes instead of leaving it as "no"
3660 (trivial change). Problem and patch reported by Andrew Church in:
3661 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
3663 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
3665 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
3666 three args in examples. Problem reported by Frederik Fouvry in:
3667 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
3668 Also, fix some minor spacing and punctuation bugs.
3670 2004-09-02 Akim Demaille <akim@epita.fr>
3672 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
3673 "case" to restore ordering.
3674 Reported by Stepan Kasal.
3676 2004-08-26 Akim Demaille <akim@epita.fr>

3690 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
3691 texinfo.tex for now (done by hand now).
3692 * Makefile.maint (wget_files, cvs_files):
3693 Remove ansi2knr.c; nobody uses it.
3694 (ansi2knr.c-url_prefix): Remove.
3695 (cvs-update): Fix test for failure. I don't know why it ever
3696 worked...
3698 * doc/autoconf.texi: Update URLs, some of which went stale.
3699 Use @uref rather than @href.
3701 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
3702 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
3704 * config/config.guess, config/config.sub, config/elisp-comp,
3705 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
3706 doc/fdl.texi, doc/standards.texi: Sync with master copy.
3708 * NEWS, TODO, configure.ac, bin/autoscan.in,
3709 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
3710 doc/install.texi, lib/Autom4te/Configure_ac.pm,
3711 lib/Autom4te/FileUtils.pm, lib/autoconf/general.m4,

3714 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
3715 tests/tools.at, tests/torture.at:
3716 Use "file name" rather than "filename" or "path",
3717 to be consistent with the terminology of the GNU coding standards.
3719 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
3721 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
3722 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
3723 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
3724 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
3726 More fixes to support spaces in the name of the build directory.
3727 This isn't a complete fix but it's an improvement.
3729 * bin/autoconf.as (autom4te_options): New var.
3730 Use it instead of appending to AUTOM4TE, so that we can allow
3731 spaces in the build directory's absolute name.
3732 * bin/autoheader.in ($autoconf): Allow spaces in file names.
3733 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
3734 AT_CHECK_NOESCAPE): Likewise.
3735 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
3736 main program): Likewise.
3738 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
3740 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
3741 From Ralf Corsepius in:
3742 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
3744 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
3746 * doc/autoconf.texi (Function Portability): Document isinf and
3747 and isnan. From a suggestion by Kevin Ryde.
3749 * lib/Autom4te/General.pm (END): Return correct exit status even
3750 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
3752 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
3754 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
3755 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
3756 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
3758 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
3760 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
3761 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
3762 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
3763 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
3764 * lib/autom4te.in (Automake-preselections): Preselect
3765 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
3767 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
3769 * lib/autom4te.in (Automake-preselections): Preselect
3770 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
3771 trace them.
3773 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
3775 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
3776 Tru64.
3777 * doc/autoconf.texi (Shellology): Mention BIN_SH.
3778 Document problem with "`""`" in pdksh POSIX mode.
3780 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
3782 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
3783 with pdksh, too. Problem reported by Patrick Welche via
3784 Gary V. Vaughan.
3785 * doc/autoconf.texi (Shellology): Note that set -o posix is
3786 useful for pkdsh, too.
3788 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
3790 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
3791 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
3792 Don't fail if ENV or BASH_ENV is readonly.
3793 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
3794 etc. are read only. Problem reported by Ludovic Courtes.
3796 2004-06-23 Noah Misch <noah@cs.caltech.edu>
3798 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
3799 zsh, disable GLOB_SUBST to avoid backslash handling problems.
3800 (trivial change)
3802 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
3804 * doc/autoconf.texi (File System Conventions): Warn about
3805 names like "aux". Problem reported by Eric Blake.
3807 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
3808 by zero instead of array size, so that we can use any arithmetic
3809 constant expression (instead of requiring an integer constant
3810 expression). This allows us to test expressions like DBL_MAX <
3811 LDBL_MAX, which didn't conform to the C standard using the old
3812 method.
3813 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
3814 now that we can do floating-point tests at compile time.
3816 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
3818 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
3819 and LDBL_EPSILON, as the resulting expression isn't an
3820 integer constant expression and violates the C standard.
3821 Problem reported by Nelson H. F. Beebe. Also, check
3822 for "L" suffix, and check that long double doesn't have
3823 worse range or precision than double, that mixed-mode
3824 arithmetic doesn't generate a diagnostic, that double
3825 constants fit in long double.
3827 2004-06-03 Kevin Ryde <user42@zip.com.au>
3829 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
3830 malloc(0) and realloc(NULL,size).
3832 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
3833 Bob Proulx.
3835 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
3837 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
3838 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
3839 by Jim Meyering.
3841 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3843 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
3844 can be rewritten using if-then-else. Suggested by Bruno Haible.
3846 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3848 * doc/autoconf.texi (testsuite Scripts): Fix typo.
3849 Problem reported by Stepan Kasal.
3851 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3853 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
3854 change). Patch reported by Ralf Wildenhues in
3855 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
3857 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
3858 function F exists if the compiler and linker let you compile an
3859 expression like (F != 0). Recent versions of GCC optimize away
3860 the reference to F in that case, since every function address must
3861 be nonzero, so the link succeeds even if F does not exist.
3862 Problem reported by Manu in
3863 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
3865 * doc/autoconf.texi (Systemology): Standardize on the spelling of
3866 "Unix". Many uses changed.
3867 (Limitations of Builtins): Explain better why the ! command isn't
3868 portable.
3870 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
3872 * lib/autom4te.in (Automake-preselections): Preselect
3873 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
3875 2004-05-19 Kevin Ryde <user42@zip.com.au>
3877 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
3878 referencing AC_FUNC_STRERROR_R.
3880 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
3881 note pessimistic assumption when cross compiling.
3883 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
3885 * doc/autoconf.texi (Limitations of Make): Note that BSD make
3886 (until 2004) invoked subcommands with sh -e, contra POSIX.
3887 Reported by Kevin Ryde.
3889 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
3891 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
3892 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
3893 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
3894 `test -f " /usr/bin/grep"', which _always_ failed.
3895 (AC_PROG_SED): Ditto bogus PATH fix.
3896 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
3897 requires that grep correctly supports _multiple_ `-e' options, rather
3898 than stating only that grep should accept `-e'.
3900 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
3902 Port to C99, which requires that 'exit' be declared.
3904 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
3905 to ensure that stdlib.h is included.
3906 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
3907 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
3908 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
3909 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
3910 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
3911 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
3912 when using 'exit' in a test; C99 requires that 'exit' be declared.
3914 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
3916 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
3917 now prefers 'grep' implementations that accept -e.
3918 (Limitations of Usual Tools): Describe problems of traditional
3919 egrep and fgrep with long input lines, and of traditional grep
3920 with -e.
3921 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
3922 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
3923 All callers changed. Append /usr/xpg4/bin to the PATH, for
3924 Solaris.
3925 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
3926 the user with complaints about multiple -e options.
3927 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
3928 Define it with AC_PROG_GREP.
3929 * configure.ac (AC_PROG_GREP): Add.
3930 * lib/freeze.mk (GREP): New macro.
3932 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
3934 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
3935 a possible candidate only after all others fail, rather than
3936 consulting it first. This improves backward compatibility by
3937 better reflecting the way shell selection occurred in previous
3938 versions of Autoconf, and should help to avoid triggering latent
3939 problems in other packages, such as the one in Automake where zsh
3940 is not handled robustly:
3941 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
3942 Although it is not Autoconf's responsibility to work around
3943 problems in Automake, it nevertheless makes sense to avoid
3944 introducing unnecessary incompatibilites.
3946 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
3947 Gary V. Vaughan <gary@gnu.org>
3949 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
3950 how deeply nested we are when a suitable tool is found, set the
3951 ac_path_TOOL_found flag.
3952 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
3953 nested we are in this macro. Break out of all 3 nested loops if
3954 ac_path_TOOL_found is set.
3956 2004-04-21 Gary V. Vaughan <gary@gnu.org>
3958 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
3959 of the _AS_PATH_WALK loop too if GNU flavor is found.
3961 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
3963 * doc/autoconf.texi (Limitations of Make): Update documentation
3964 for `$<'. New entry `Long lines', based on a report from Simon
3965 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
3966 paragraph about DJGPP, based on a mail from Richard Dawe.
3968 2004-04-20 Paul Eggert <eggert@twinsun.com>
3970 * tests/c.at (C keywords): Don't assume that GCC supports
3971 "restrict" and "inline", as sufficiently-old GCC versions do not
3972 (also, GCC configured to be in pedantic C89 mode does not).
3973 Problem reported by Sumit Pandya in:
3974 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
3976 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
3977 consider -g to work if it generates warnings when plain compiles
3978 don't. Problem reported by Braden McDaniel in:
3979 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
3981 * doc/autoconf.texi (Slashes): New section, to document a problem
3982 reported by Jim Meyering in:
3983 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
3985 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
3986 linker output files before linking, to work around IRIX 6 linker bug.
3987 Problem reported by Rainer Orth in:
3988 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
3990 2004-04-20 Gary V. Vaughan <gary@gnu.org>
3992 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
3993 best tool so far counter rely on the tool path variable name to
3994 avoid checks for one tool being affected by the results of running
3995 the length check on a previous tool.
3997 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
3998 match expression argument, as different greps have different
3999 regular expression flavours.
4000 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4001 literals.
4002 (AC_PROG_EGREP): Pass 'EGREP$'.
4003 (AC_PROG_GREP): Pass 'GREP$'.
4005 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4007 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4008 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4010 2004-03-29 Paul Eggert <eggert@twinsun.com>
4012 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4013 Types, Specific Compiler Characteristics, System Services,
4014 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4015 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4016 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4017 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4018 Likewise.
4019 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4020 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4021 AC_TYPE_OFF_T): Likewise.
4022 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4023 Likewise.
4025 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
4026 pacify libtool 1.5.2. Fix quoting problems in sed command.
4028 2004-03-28 Paul Eggert <eggert@twinsun.com>
4030 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4031 now defines HAVE_DECL_TZNAME if it is declared, when
4032 HAVE_STRUCT_TM_TM_ZONE is not defined.
4033 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4034 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4035 for HAVE_TZNAME.
4037 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4039 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4040 superfluous backslashing of quotes (") in sed expressions;
4041 thanks to Paul Eggert.
4043 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4045 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4046 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4047 H. F. Beebe for the bug report.
4049 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4051 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4052 quoted -cmdline argument in Portland Group compiler (bug
4053 reported by Jeffrey J. Barteet).
4055 2004-03-25 Kevin Ryde <user42@zip.com.au>
4057 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4058 (Run Time): ... here, where it's now mentioned.
4060 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
4062 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4063 inherits from language Autoconf-without-aclocal-m4.
4064 (Customizing autom4te): Adjust example; the cache must now be
4065 disabled for language Autoconf-without-aclocal-m4.
4067 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
4068 Nathanael Nerode <neroden@twcny.rr.com>
4070 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
4071 AC_CHECK_TOOLS): Warn if a cross-tool is found without
4072 a prefix.
4073 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
4074 AC_CHECK_TARGET_TOOLS): New macros.
4075 * doc/autoconf.texi (Generic Programs): Document
4076 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
4077 AC_CHECK_TARGET_TOOLS, and warn for future changes
4078 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
4079 AC_CHECK_TOOLS.
4080 (Specifying Names): Document the reason for these future
4081 behavioral changes.
4082 * tests/mktests.sh: Do not generate tests for the
4083 new macros.
4084 * NEWS: Document these changes.
4086 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4087 they make TeX hang up.
4089 2004-03-15 Paul Eggert <eggert@bogus.example.com>
4091 * NEWS: New macro AC_CHECK_ALIGNOF.
4092 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4093 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4094 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4095 vowel.
4096 (AC_CHECK_ALIGNOF): New macro.
4097 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
4098 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
4099 those for sizeof.
4101 2004-03-03 Paul Eggert <eggert@twinsun.com>
4103 * bin/Makefile.am (edit): Don't use $< in a context where
4104 POSIX doesn't require support for it. Use $@.in instead.
4105 Problem reported by Anthony N. Frasso in
4106 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4107 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4109 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4111 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4112 from the next generation of Libtool.
4113 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4115 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4117 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4118 is not always thread-safe. Report from Nathanael Nerode.
4120 2004-02-18 Paul Eggert <eggert@twinsun.com>
4122 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4123 problem on QNX reported by Stephen Rasku in
4124 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4126 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4127 $(m4sh_m4f_dependencies); this removes a FIXME.
4128 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4129 (MAINTAINERCLEANFILES): Split into pieces,
4130 one per related section. Add $(srcdir)/wrapper.in.
4132 2004-02-09 Paul Eggert <eggert@twinsun.com>
4134 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4135 AC_SUBST provides no portable way to escape literal newlines.
4137 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4138 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4139 Darwin uses -lcrt2.o and there's little point to cataloging all
4140 the system variants. Partial fix reported by Andreas Waechter in:
4141 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4142 for bug reported by Nelson H. F. Beebe in:

4145 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
4147 * doc/autoconf.texi (AU_DEFUN): Fix English,
4148 suggested by Paul Eggert.
4149 * lib/autoconf/autoupdate.m4: Correct reference to
4150 acobsolete.m4, suggested by Alexandre Duret-Lutz.
4152 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
4154 * bin/autoupdate.in: Define __file__ so that warnings
4155 refer to the correct file.
4156 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4157 the behavior of the third argument.
4158 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4159 correctly the behavior of the third argument. Document
4160 what the three macros that AU_DEFUN defines do. Fix
4161 warning message when the third argument includes $0
4162 (reported by Alexandre Duret-Lutz).
4164 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4165 Eric Sunshine <sunshine@sunshineco.com>
4166 Paul Eggert <eggert@twinsun.com>
4168 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4169 (AS_INIT): Output shell initialization there. Removed optional
4170 parameter. Expand _AS_SHELL_FN_SPY.
4171 (AS_INIT_WITH_SHELL_FN): Removed.
4172 (_AS_SHELL_FN_SPY): New macro.
4173 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4174 macros.
4175 (AS_SHELL_SANITIZE): Remove loop to find better shell
4176 and documentation for the parameter.
4177 (_AS_DETECT_BETTER_SHELL): Move it here.
4178 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
4179 (_AS_RUN): Move it here, support testing with eval.
4180 (AS_REQUIRE_SHELL_FN): Require shell functions when
4181 it is used.
4182 (_AS_LINENO_WORKS): Put around braces, we do not
4183 trigger the bash bug anymore.
4184 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4185 use AS_INIT_WITH_SHELL_FN.
4186 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4188 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4190 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
4191 * doc/autoconf.texi: Don't say that the third parameter
4192 is broken.
4193 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
4194 (AU_DEFUN): Honor the third parameter, create autoupdate
4195 macros with AU_DEFINE.
4196 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
4197 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
4198 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
4199 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
4200 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
4201 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,
4202 AC_XENIX_DIR): Likewise.
4203 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
4204 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
4205 * lib/autoconf/status.m4: Remove FIXME.
4206 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
4207 that the macro is not present anymore in the updated
4208 configure.ac.
4209 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
4210 of autoupdate.
4212 2004-01-28 Paul Eggert <eggert@twinsun.com>
4214 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
4215 copyright years.
4216 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4217 2003 (except 1997) to the list of copyright years. This undoes
4218 the 2003-05-22 change, which removed the older years from the list.
4219 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4221 2004-01-27 Gary V. Vaughan <gary@gnu.org>
4222 Albert Chin-A-Young <china@thewrittenword.com>
4224 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
4225 grep or ggrep program in PATH that accepts as long lines as
4226 possible.
4227 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4228 AC_PROG_GREP.
4229 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4230 egrep and fgrep respectively if $GREP -E/-F don't work.
4231 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4232 _AC_PROG_GREP, and AC_PROG_SED.
4233 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4234 longest input length accepted by a command.
4235 (AC_PROG_SED): Use it.
4236 * doc/autoconf.texi (Particular Programs): Document the changes.
4237 * NEWS: Updated.
4239 2004-01-27 Paul Eggert <eggert@twinsun.com>
4241 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
4242 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
4243 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
4244 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
4246 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4247 bin/autoconf.in, config/Makefile.in, config/config.guess,
4248 config/config.sub, config/install-sh, config/mdate-sh,

4259 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
4260 tests/actypes.at: Regenerate and/or sync with original
4261 sources.
4263 2004-01-26 Paul Eggert <eggert@twinsun.com>
4265 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4266 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4267 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4268 not <inttypes.h>. Problem reported by Tim Mooney in
4269 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4270 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4271 Likewise.
4273 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4274 otherwise "make check" fails because it forbids cmp (I guess
4275 because cmp treats files as binary on DOS-like systems).
4277 * tests/mktests.sh: Update copyright date to 2004, since some tests
4278 have changed in 2004.
4280 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4282 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4283 non-truncating sed or gsed program in PATH.
4284 * tests/acprograms.at: Add it.
4285 * doc/autoconf.texi (Particular Programs): Document it.
4286 * NEWS: Updated.
4288 2004-01-15 Paul Eggert <eggert@twinsun.com>
4290 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4291 -std1 disables some useful extensions on Tru64. Problem reported
4292 by N. Lichtmaier in
4293 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4295 2004-01-14 Paul Eggert <eggert@twinsun.com>
4297 * doc/autoconf.texi (Programming in M4sh): Document that
4298 AS_MKDIR_P succeeds if the destination is a symbolic link
4299 to an existing directory.
4300 (Limitations of Usual Tools): Note that mkdir -p might not
4301 succeed on symlinks to directories.
4303 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4305 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4306 * bin/autoheader.in: Grammar fix in message.
4307 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4308 Test for dir before calling mkdir -p. (trivial changes)
4310 2004-01-13 Eric Blake <ebb9@byu.net>
4312 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4313 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4315 2004-01-10 Jim Meyering <jim@meyering.net>
4317 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4319 2004-01-09 Paul Eggert <eggert@twinsun.com>
4321 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4322 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4323 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4324 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4325 AC_COMPILE_IFELSE, since we now assume our caller invokes
4326 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4327 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4328 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4329 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4331 2004-01-07 Paul Eggert <eggert@twinsun.com>
4333 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4334 `"'...'"`, as it's confusing (and I suspect it may not work on
4335 some platforms). The code was incorrect anyway, as it assumed
4336 that \$ evaluated to itself in that context. Reported by
4337 Alexandre Duret-Lutz.
4339 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4341 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
4342 and _LT_AC_TAGCONFIG.
4344 2004-01-06 Paul Eggert <eggert@twinsun.com>
4346 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4347 example, and add more examples. Reported by Eric Sunshine.
4349 2004-01-05 Paul Eggert <eggert@twinsun.com>
4351 * doc/autoconf.texi (Limitations of Usual Tools):
4352 Remove warning against "rm -fr" introduced yesterday; it
4353 was a false alarm.
4355 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4356 autoscan, autoupdate, ifnames): Don't use chmod -w.
4357 * lib/Makefile.am (autom4te.cfg): Likewise.
4358 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4359 "chmod -w".
4361 2004-01-04 Paul Eggert <eggert@twinsun.com>
4362 Paolo Bonzini <bonzini@gnu.org>
4364 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
4365 by doing lineno substitution only on lines containing "$LINENO".
4367 2004-01-04 Paul Eggert <eggert@twinsun.com>
4369 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4370 Use "rm -f" to remove conftest.sed, not plain "rm".
4371 Bug reported by David Relson in
4372 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4374 * Makefile.am (autom4te-update):
4375 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4376 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4377 * doc/autoconf.texi (Guidelines): Likewise.
4378 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

4383 * tests/Makefile.am (clean-local): Likewise.
4384 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
4385 srcdir): Likewise.
4386 * doc/autoconf.texi (Limitations of Usual Tools):
4387 Warn against "rm -fr".
4389 2004-01-03 Paul Eggert <eggert@twinsun.com>
4391 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4392 -c -o might not work. From a suggestion by Kevin Ryde.
4393 (C Compiler, Generating Sources, Limitations
4394 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4395 Don't put '-o' after non-options, as POSIX doesn't allow this.
4396 Mention that cc's name might be gcc or c89 or whatever.
4398 2004-01-04 Kevin Ryde <user42@zip.com.au>
4400 * doc/autoconf.texi: Add various further index entries.
4402 2003-12-29 Paul Eggert <eggert@twinsun.com>
4404 * bin/autoreconf.in (autoreconf_current_directory):
4405 Fix typo: mkdir without umask arg.
4407 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4409 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4410 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
4411 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
4412 explanation clearer.
4414 2003-12-24 Andreas Schwab <schwab@suse.de>
4416 * doc/autoconf.texi (Default Includes): Fix misspelling of
4417 AC_INCLUDES_DEFAULT.
4419 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
4421 * configure.ac: Test if sh -n works.
4422 * configure: Regenerate.
4423 * tests/atlocal.in: Store the result here.
4424 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
4425 tools.at, looking in atlocal's ac_cv_sh_n_works instead
4426 of explicitly testing.
4427 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
4428 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
4429 * tests/tools.at (Syntax of the shell scripts): Simplify
4430 using AT_CHECK_SHELL_SYNTAX.
4431 (Syntax of the Perl scripts): Remove definition of
4432 AT_CHECK_PERL_SYNTAX.
4434 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
4436 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
4437 stderr to /dev/null.
4438 * bin/autoconf.in: Regenerate.
4439 * bin/wrapper.in: Regenerate.
4441 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
4443 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
4444 Extracted from AS_SHELL_SANITIZE.
4445 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
4446 macros.
4447 (AS_SHELL_SANITIZE): Move reinvocation code from
4448 _AS_LINENO_WORKS, use it to find out if shell
4449 functions work.
4450 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
4451 does not work.
4452 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
4453 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
4454 was called.

4464 (&sizes): New.
4465 Use them.

4467 them on the fly.
4469 2003-11-24 Akim Demaille <akim@epita.fr>
4471 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

4499 parameter of AU_DEFUN.
4500 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

4504 the expanded body, consistently with other macros such as AC_USG.
4506 2003-11-17 Paul Eggert <eggert@twinsun.com>
4508 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
4509 into the initial confdefs.h, to work around a bug in NextStep 3.3
4510 patch 3 reported by Eric Sunshine.
4512 2003-11-15 Kevin Ryde <user42@zip.com.au>
4514 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
4515 than $target since the latter is not usual, add guidelines on when to
4516 use or not use the system type.
4518 2003-11-12 Derek Price <derek@ximbiot.com>
4520 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
4521 typo misrepaired by an auto-spellcheck.
4523 2003-11-12 Akim Demaille <akim@epita.fr>

4526 --force-missing unless it actually supports it.
4527 From Debian #219336.
4529 2003-11-12 Akim Demaille <akim@epita.fr>

4675 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
4676 cross test.
4678 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
4680 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
4681 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

4692 Issue a more-informative diagnostic.
4693 Problems reported by Eric Sunshine.
4695 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
4697 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
4698 -mGLOB_options_string stuff for Intel ifc, which can cause

4718 -lcrt[01].o.
4720 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
4722 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
4723 cache variable instead of $G77 to decide whether to include -O2,
4724 since $G77 is specific to Fortran 77.

4728 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
4729 free" flag. Re-order flags tested into rough order of popularity.
4731 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4733 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
4734 arguments so that it can be used with syntax identical to
4735 AC_PROG_F77, and so that we can more easily decide to
4736 remove/deprecate the DIALECT optional argument in the future if it
4737 proves troublesome.
4738 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
4739 non-freeform-supporting compilers. Document freeform flags.
4741 2003-10-03 Akim Demaille <akim@epita.fr>
4743 * configure.ac: Look for emacs, not macs.

4746 2003-10-03 Akim Demaille <akim@epita.fr>
4748 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
4749 * bin/autoreconf.in (autoreconf_current_directory): Create the

4751 Suggested by Alexandre Duret-Lutz.
4753 2003-10-03 Akim Demaille <akim@epita.fr>
4755 * configure.ac: Quotation and formatting changes.

4777 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
4778 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
4780 2003-09-30 Akim Demaille <akim@epita.fr>
4782 * config/announce-gen (&print_news_deltas): Extracted from...
4783 (&print_changelog_deltas): here.

4802 Problem reported by Lars J. Aas in
4803 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
4804 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
4805 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
4806 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
4808 2003-09-26 Akim Demaille <akim@epita.fr>
4810 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
4811 directory for AC_CONFIG_COMMANDS' first argument exists.
4812 This makes valid the invocation of _AC_SRCPATH that follows.
4813 Reported by Eric Sunshine.
4814 * doc/autoconf.texi (Configuration Commands): Adjust.
4816 2003-09-26 Akim Demaille <akim@epita.fr>
4818 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
4819 Reported by Ralf Corsepius.

4823 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
4824 arguments.
4825 Actually, use AU_ALIAS.
4826 From Bruno Haible.

4835 2003-09-26 Akim Demaille <akim@epita.fr>
4837 The test suite are sometimes assigning timings incorrectly.
4838 Reported by Henk Krus.
4839 Diagnosed by Nicolas Joly.
4841 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
4842 AT_help_all.
4843 Instead of making AT_help a sequence of assignments to grow
4844 $at_help_all, just make AT_help_all be the growing contents of
4845 $at_help_all, and make a single assignment in...
4846 (AT_INIT): here.
4847 (at_times_skip): Flip the meaning and rename as...
4848 (at_times_p): this.
4849 (AT_INIT): When summarizing the test that ran, remove
4850 $at_times_file after use, and check it is present before trying to
4851 use it.
4853 2003-09-25 Akim Demaille <akim@epita.fr>
4855 Version 2.57d.
4857 * bin/Makefile.am (edit): Handle '@configure_input@'.

4859 (ifnames): chmod -w.
4860 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
4861 executables, not bin/ executables! Otherwise all the magic needed
4862 to find non installed files is turned off. This caused a failure
4863 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
4864 as found in its environment (sent by tests/autoreconf): pointing
4865 to bin/autom4te that could not find its files.
4866 * tests/mktests.sh: Force the replacement of generated files, for
4867 the sake of "mv" program that are interactive when overwriting a
4868 -w file.
4869 * config/install-sh: Upgrade from CVS Automake.
4871 2003-09-23 Paul Eggert <eggert@twinsun.com>

4874 versus test -L issues.
4876 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
4877 Paul Eggert <eggert@twinsun.com>
4879 Trivial change to support GCC's configuration procedure.
4880 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
4881 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
4882 about inconsistency if the preprocessor is set to give errors for
4883 any warning.
4884 * doc/autoconf.texi (C Compiler Characteristics): Document this.
4886 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

4909 * doc/autoconf.texi (Header Portability): linux/random.h.
4910 From Peter Hendrickson.
4912 2003-09-10 Akim Demaille <akim@epita.fr>
4914 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
4915 willing to edit the output files.
4917 2003-09-10 Akim Demaille <akim@epita.fr>
4919 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
4920 and AC_FC_FREEFORM.
4921 * tests/mktests.sh: Skip AC_FC_SRCEXT.
4922 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

4938 Improve the accuracy of the wording about obsolescence.
4939 From a suggestion by Ian Lance Taylor in
4940 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
4942 2003-09-05 Paul Eggert <eggert@twinsun.com>
4944 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
4945 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
4947 2003-09-04 Akim Demaille <akim@epita.fr>
4949 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
4950 AC_FUNC_WAIT3.
4952 2003-09-04 Akim Demaille <akim@epita.fr>
4954 * bin/autom4te.in: Use &fatal where more appropriate than &error.
4955 (freeze): When exiting, use $exit_code.

4962 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
4964 Add support for newer Fortran dialects. The F77 interface is
4965 unchanged, and continues to support Fortran 77. New FC macros
4966 correspond to all the old F77 macros, with output variables FC,
4967 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
4968 available dialect, but older dialects can be specified. There are
4969 new macros AC_FC_SRCEXT to set the source extension, and
4970 AC_FC_FREEFORM to accept free-form source files.
4972 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
4973 New macros.
4974 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

4999 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5000 Document problems with timestamp resolution that 'make', 'cp -p', and
5001 'touch -r' have.
5003 2003-08-27 Akim Demaille <akim@epita.fr>
5005 * tests/m4sugar.at (cross_warning): Make sure to enable the
5006 output, so that we can track spurious m4sugar output.
5007 * tests/local.at: Require 2.57.
5008 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5009 are defaulted by AT_CHECK anyway.
5010 Use AT_CHECK_AUTOM4TE.
5011 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5012 missing dnl.
5014 2003-08-27 Akim Demaille <akim@epita.fr>
5016 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5017 when -Wobsolete is set.
5018 Set it on by default.
5019 Suggested by Klee Dienes.
5021 2003-08-27 Akim Demaille <akim@epita.fr>
5023 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
5024 documentation.
5025 From Guido Draheim.
5027 2003-08-26 Akim Demaille <akim@epita.fr>
5029 * doc/autoconf.texi (Output): Make clear that one can run code
5030 after AC_OUTPUT.
5032 2003-08-25 Akim Demaille <akim@epita.fr>
5034 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
5035 CVS Bison.
5037 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
5039 * bin/autoreconf.in (parse_args): Do not pass --no-force to

5051 2003-08-22 Akim Demaille <akim@epita.fr>
5053 Version 2.57b.
5055 * Makefile.cfg (local-checks-to-skip): New.
5056 * Makefile.maint (local-check): Rename as...
5057 (local-checks-available): this.
5058 (local-check): New.
5060 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
5061 * configure.ac: Require Automake 1.7.6.
5063 2003-08-22 Akim Demaille <akim@epita.fr>
5065 Output stack traces in warnings.
5067 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
5068 Replace the former...
5069 (m4_warn): Pass the call stack to _m4_warn.
5070 * bin/autom4te.in: Adjust to output the call stack.
5071 * tests/m4sugar.at (m4@&t@_warn): Adjust.
5073 2003-08-22 Akim Demaille <akim@epita.fr>
5075 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
5076 * bin/autom4te.in: Adjust.
5078 2003-08-21 Akim Demaille <akim@epita.fr>
5080 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
5081 (&verbose): Remove.
5082 (&getopt): Adjust the note and verb channels, depending upon
5083 --verbose.
5084 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
5085 * bin/autoupdate.in: Adjust.
5086 Use &verb, not &verbose.
5088 2003-08-21 Akim Demaille <akim@epita.fr>
5090 * bin/autoheader.in (&parse_args): Use &parse_warnings and
5091 &parse_WARNINGS.
5092 ($help): Use Autom4te::ChannelDefs::usage.
5093 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5094 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5096 2003-08-21 Akim Demaille <akim@epita.fr>
5098 First stab at preserving warnings between calls to autom4te,
5099 including when the cache is used.
5101 There are still several issues: (i) there are too many runs of m4
5102 (one for include, one for warnings, and some more), (ii) warnings
5103 spreading on several lines are not handled gracefully, (iii) the
5104 code meant to have the call stack display for errors does not work
5105 (its handling should move from m4 to autom4te).
5107 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5108 Use them.
5109 (@preselect): Add m4_warn.
5110 ($exit_status): Remove, use $exit_code.
5111 ($help): Use Autom4te::ChannelDefs::usage.
5112 (&handle_m4): No longer define the m4_warnings.
5113 At each run, extract and report the warnings.
5114 Always cache the result, including if the exit status is on
5115 failure, since if nothing changes, we should result in the same
5116 failure, hence we can use the cache.
5117 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5118 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5119 Remove.
5120 (m4_warn): Redefine as a do-nothing: it is its invocation that
5121 matters, as warnings are now reported via traces.
5122 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5123 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5124 the latter reveals calls to the former.
5126 Adjust the tests.
5128 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5130 2003-08-21 Akim Demaille <akim@epita.fr>
5132 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5133 Use them.
5135 2003-08-21 Akim Demaille <akim@epita.fr>
5137 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5138 forward order.
5139 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5140 (&parse_warnings): Accept a list of warning requests.
5141 (&usage): Return a string, not a side effect.
5142 (cross): New warning category.
5144 2003-08-21 Akim Demaille <akim@epita.fr>
5146 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5147 (&require_configure_ac): Accept an optional directory argument.
5148 ($configure_ac): Remove.
5149 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5150 (&catfile): Remove.
5151 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5152 * bin/autoscan.in: Adjust.
5154 2003-08-20 Akim Demaille <akim@epita.fr>
5156 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5157 Reported by Alexandre Duret-Lutz.
5159 2003-08-20 Akim Demaille <akim@epita.fr>
5161 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5162 * bin/autom4te: Adjust.
5163 In particular, be Autoconf tools are really silent when properly
5164 working, bind the verbosity of the 'note' channel to $verbose.
5165 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5166 (&xsystem, &contents): Remove, since they are exported by...
5167 * lib/Autom4te/FileUtils.pm: this.
5168 More perldoc.
5169 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5170 * lib/Autom4te/FileUtils.pm: here.
5172 2003-08-20 Akim Demaille <akim@epita.fr>
5174 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5175 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
5176 from CVS Automake.
5178 2003-08-20 Akim Demaille <akim@epita.fr>
5180 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
5181 (autom4te-update): New.
5182 * Makefile.cfg (update): Bind autom4te-update.
5184 2003-08-19 Derek Price <derek@ximbiot.com>
5186 * lib/autotest/general.m4: Comment various HELP_* diversions.
5187 (PARSE_ARGS_BEGIN): New section for option parsing related
5188 initialization.

5194 * config/announce-gen, Makefile.cfg: New.
5195 * Makefile.am: Adjust.
5196 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
5198 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5200 * lib/autom4te.in (Automake-preselections): Preselect
5201 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
5202 and m4_sinclude.
5204 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5206 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
5207 (Autoconf-without-aclocal-m4): ... this new language.
5208 * doc/autoconf.texi (autom4te Invocation): Mention
5209 Autoconf-without-aclocal-m4.

5213 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
5214 RUN-IF-PASS optional arguments.

5223 STDOUT & STDERR arguments.
5225 2003-08-14 Derek Price <derek@ximbiot.com>
5227 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5228 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5229 shorter column three. Add DESCRIPTION to log file content.
5231 2003-08-13 Derek Price <derek@ximbiot.com>
5233 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
5234 output.
5236 2003-08-12 Derek Price <derek@ximbiot.com>
5238 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
5239 (AT_CHECK_NOESCAPE): Move core functionality to...
5240 (_AT_CHECK): ...this new macro.
5242 2003-08-07 Derek Price <derek@ximbiot.com>
5244 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
5245 (AT_CHECK_NOESCAPE): ...to this new macro.
5247 2003-07-31 Paul Eggert <eggert@twinsun.com>
5249 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5250 in Bash 2.01. Problem reported by Brian Gough in
5251 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
5253 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
5255 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
5256 -lcrt1.o, for OS X. (trivial change)
5258 2003-07-07 Paul Eggert <eggert@twinsun.com>
5260 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
5261 inside '#ifndef __cplusplus'. Problem reported by
5262 Bob Friesenhahn.
5264 2003-07-06 Bill Clarke <llib@computer.org>
5266 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5267 'long', not 'int', for benefit of Sun's recent C++ compilers
5268 (trivial change). See:
5269 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5270 (This really should be 'intptr_t', not 'long', but that would
5271 take more work.)
5273 2003-06-25 Akim Demaille <akim@epita.fr>
5275 * lib/Makefile.am (autom4te.cfg): Make it read only.
5276 Depend on Makefile since it contains substitutions.
5277 From Paolo Bonzini.
5278 * lib/autom4te.in (args): Add local.at? for Autotest args.
5279 This change was made on autom4te.cfg which is generated.
5280 Reported by Raja R. Harinath.
5282 2003-06-25 Akim Demaille <akim@epita.fr>
5284 * doc/autoconf.texi (Header Portability): sys/mount.h.
5285 From Gareth McCaughan.
5287 2003-06-23 Akim Demaille <akim@epita.fr>
5289 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5290 not all of them. This fixes 1. the fact that when testing
5291 Autoconf there are many many config.log, 2. the incorrect use of
5292 top_srcdir to find config.log.
5293 Don't mix the detailed output of failed test with the summary of
5294 failures. Rather, append detailed log afterwards.
5296 2003-06-23 Akim Demaille <akim@epita.fr>
5298 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5299 always run: output config.log on $at_group_log.
5301 2003-06-23 Akim Demaille <akim@epita.fr>
5303 * tests/torture.at (#define header templates): Don't use quotes in
5304 C++ comments as it puzzles Emacs' sh font-lock-mode.
5306 2003-06-23 Akim Demaille <akim@epita.fr>
5308 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5309 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5310 * tests/atspecific.m4: Rename as...

5312 * tests/suite.at: Move the globals into...
5313 * tests/local.at: here.
5314 * tests/Makefile.am: Adjust.
5315 * doc/autoconf.texi (testsuite Scripts): Adjust.
5317 2003-06-21 Kevin Ryde <user42@zip.com.au>
5319 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5320 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5321 ensuring we add -std1 for full-ANSI.
5323 * doc/autoconf.texi (hdrindex): New macro.
5324 Add index entries for portability of various standard header files.
5326 2003-06-20 Akim Demaille <akim@epita.fr>
5328 * configure.ac: Bump to 2.57b.
5330 2003-06-20 Akim Demaille <akim@epita.fr>
5332 Version 2.57a.
5334 2003-06-20 Akim Demaille <akim@epita.fr>
5336 * bin/autom4te.in: Don't rely on $HOME being defined.
5337 Reported by Marc Espie as PR/233.
5339 2003-06-20 Akim Demaille <akim@epita.fr>
5341 * lib/autotest/general.m4: Use at_times_file only if used.
5342 From Nicolas Joly.
5344 2003-06-20 Akim Demaille <akim@epita.fr>
5346 * config/config.guess, config/config.sub, config/elisp-comp,
5347 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
5348 Update from masters.
5350 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
5352 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
5353 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5354 (TEST_SCRIPT): New diversion.
5355 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5356 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5357 (AT_INIT): Support for expected failures.
5359 2003-06-02 Akim Demaille <akim@epita.fr>
5361 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
5362 changes.
5363 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5364 Autoconf nor Automake.
5365 (&contents): New, from Automake.
5366 PODify.
5368 2003-05-28 Paul Eggert <eggert@twinsun.com>
5370 * NEWS, doc/autoconf.texi (Particular Functions),
5371 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5372 is the inverse of localtime.
5374 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5376 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5377 (handle_exec_errors): New function. Work around $! being
5378 altered by WEXITSTATUS.
5379 (xqx, xsystem): Use handle_exec_errors.
5381 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5383 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5384 Do not call `_exit()', simply modify `$?'.
5385 (xsystem): Reset $! before running system, and check it afterward.
5386 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5387 63 for version mismatches.
5389 2003-05-23 Akim Demaille <akim@epita.fr>
5391 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5392 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5393 the middle of a line).
5394 * lib/m4sugar/m4sugar.m4: Likewise.
5395 Remove useless spaces in comments.
5397 2003-05-23 Akim Demaille <akim@epita.fr>
5399 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5400 exit 63, so that we (or Automake's "missing") can tell the
5401 difference with a plain failure.
5402 * doc/autoconf.texi (Notices): Adjust.
5404 2003-05-23 Akim Demaille <akim@epita.fr>
5406 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5407 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5408 White spaces cleanup.
5410 2003-05-22 Jim Meyering <jim@meyering.net>
5411 Paul Eggert <eggert@twinsun.com>
5413 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5414 Remove `#include <stdlib.h>' from the list; we should never
5415 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5416 resulting namespace pollution would cause other tests to fail.
5417 Configure scripts run with some older versions of g++ and HP's
5418 aCC would fail due to such an #include. Problems reported by
5419 Matthew Mueller in <http://bugs.debian.org/120704> and by
5420 Keith Bostic in
5421 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5422 In the test, use the test declaration before including <stdlib.h>,
5423 as that's closer to how it'll be used.
5425 2003-05-23 Akim Demaille <akim@epita.fr>
5427 * doc/autoconf.texi (Header Portability): ucred.h.
5428 From Ian Redfern.
5430 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5432 Overhaul Autotest's logging: generate separate log files
5433 in testsuite.dir/NNN/testsuite.log, and append them to
5434 testsuite.log instead of re-running the test verbosely.
5436 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5437 file descriptor, write 0 to at_status_file instead of setting
5438 at_status=0, initialize some new variables (at_status_file,
5439 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5440 to rerun the tests, instead append the at_group_log to the
5441 at_suite_log when a test fails.
5442 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5443 with the AS_MESSAGE_LOG_FD redirected to stdout.
5444 (AT_CLEANUP): save the output status in $at_status_file
5445 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5446 its original place.
5447 (AT_CHECK): since tests are run with a redirected stdout,
5448 and used to be re-run in verbose mode, turn some $at_verbose
5449 into echo, and don't redirect the output of testing stdout
5450 and stderr.
5452 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5453 the name of the debugging directory and information about
5454 its contents.
5456 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5458 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
5459 parameter.

5571 and truncate.
5573 2003-05-06 Akim Demaille <akim@epita.fr>
5575 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5576 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5577 by aclocal.m4 is changed it might require the importing of another
5578 m4 extension file, i.e., aclocal must be run.
5580 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5581 (&parse_args): Use --force with aclocal if required and supported.
5582 (&autoreconf_current_directory): Use &run_aclocal.

5589 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
5590 argument instead of a file name, so that the request file remains
5591 open during the whole autom4te run.
5592 ($icache_file): New.
5593 (&freeze): Lock the $icache_file.
5595 2003-04-29 Derek Price <derek@ximbiot.com>
5597 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
5598 seperator with m4_append_uniq(). It doesn't work.
5599 (AT_CLEANUP): Add `;' to end of at_help_all.
5600 (AT_INIT): Allow --keywords to be specified more than once. When
5601 grepping $at_help_all for keywords, use the field and keyword
5602 seperators to ensure a complete keyword match. Alter at_prev handling
5603 to support the new --keywords behavior.
5605 2003-04-27 Karl Berry <karl@freefriends.org>
5607 * doc/autoconf.texi: Make the dir entries in the autoconf manual
5608 align better with others. I also made some of the individual
5609 entries on one line, for brevity and to make it easier for me to
5610 sort my dir-example file in the Texinfo distribution :).
5612 2003-04-12 Jim Meyering <jim@meyering.net>

5677 header causes problems.
5679 2003-03-28 Akim Demaille <akim@epita.fr>
5681 * tests/torture.at (Configuring subdirectories): Require aclocal
5682 1.4, otherwise the test fails, as it does support configure.ac.

5687 * doc/autoconf.texi (C Compiler): `#line' portability.

5693 layout in order to allow scripting around test groups.
5695 2003-03-27 Derek Price <derek@ximbiot.com>
5697 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
5698 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
5699 use new diversions in preparation for accepting new arguments and

5707 (AC_HELP_STRING): AU_DEFUN to...
5708 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
5709 * tests/m4sh.at (AS_HELP_STRING): New test.
5711 * tests/acgeneral.at: Regenerated.
5713 2003-03-26 Derek Price <derek@ximbiot.com>
5715 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
5716 sense. Verbosify the diversion definitions comment.

5720 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

5752 * doc/autoconf.texi (Limitations of Make): Remove the section
5753 about `$<' in inference rules, it was a bogus interpretation of
5754 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
5755 Tru64 make in the "target lookup" section.
5756 (Automake): Automake 1.5+ no longer requires special tools to be
5757 present on the developer's host.

5765 * bin/autom4te.in (BEGIN): Likewise.
5766 * bin/autoreconf.in (BEGIN): Likewise.
5767 * bin/autoscan.in (BEGIN): Likewise.
5768 * bin/autoupdate.in (BEGIN): Likewise.

5773 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
5774 to cope with DOS-style absolute paths, when constructing
5775 ${ac_make}.
5777 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
5778 When constructing paths with IFS=:, quote the path. If we're
5779 constructing a DOS-style absolute path, we don't want to split it
5780 on the colon.
5782 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
5783 in description.
5785 2003-02-25 Pavel Roskin <proski@gnu.org>

5793 2002-09-01 patch by replacing "test -n" with "test -z".
5794 This fixes a bug found by Jeff Painter and reported by Tom Epperly in

5797 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
5798 to fix a mismatch between example and discussion.
5800 2003-02-24 Kevin Ryde <user42@zip.com.au>
5802 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
5803 format starting with "-".
5805 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5807 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
5808 is not portable inside Makefile.
5810 2003-02-20 Akim Demaille <akim@epita.fr>
5812 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
5813 compiler says yeah, but preproc says nope, compiler is right.
5814 Conversely, prompt the reader to send a bug report to the
5815 maintainers of the package, not of Autoconf.
5817 2003-02-20 Klee Dienes <kdienes@apple.com>
5819 * bin/autoreconf.in (autoreconf_current_directory): Properly
5820 handle an empty aclocal.m4.

5824 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
5825 $ac_prefix_program.
5826 From Larry Jones.
5828 2002-12-23 Paul Eggert <eggert@twinsun.com>
5830 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
5831 innocuous variant befor including <limits.h> or <assert.h>. This
5832 works around a bug reported by Albert Chin: HP-UX 11i
5833 (and earlier versions) have a <limits.h> that declares
5834 gettimeofday and many other functions.
5836 2002-12-03 Paul Eggert <eggert@twinsun.com>
5838 Version 2.57.
5840 * NEWS, configure.ac: Update version.
5842 * doc/fdl.texi: Upgrade to FDL version 1.2.
5844 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
5845 nontrivially in main's body, so that f's external declaration is
5846 not optimized away in AIX. This should fix the bug reported by
5847 Martin Frydl in
5848 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
5850 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
5851 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
5852 defined, to support freestanding compilers. This should fix the
5853 bug reported by Momchil Velkov in
5854 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
5856 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
5857 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
5858 obsolete AC_CHECK_TYPE. The missing empty arg was reported
5859 by Simon Josefsson in

5862 * Makefile.maint (www-gnu): New macro.
5863 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
5864 the location has moved.
5866 2002-12-02 Martin Frydl <martin@systinet.com>
5868 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
5869 \(.*\) match is too long and there is something more to be checked.
5870 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
5872 2002-11-15 Akim Demaille <akim@epita.fr>
5874 Version 2.56.
5876 * config/install-sh: chmod +x.
5877 From Paul Eggert.
5878 * config/move-if-change: Indenting changes.
5879 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
5880 * configure.ac (AM_INIT_AUTOMAKE): here.
5881 Require 1.7.1.
5883 2002-11-14 Akim Demaille <akim@epita.fr>
5885 Version 2.55.
5887 * config/config.guess, config/config.sub, config/install-sh:
5888 Update from masters.
5890 2002-11-14 Akim Demaille <akim@epita.fr>
5892 * Makefile.maint: Sync with Bison, i.e.:
5893 (po-check): Scan .l and .y files instead of the
5894 .c and the .h files that they generate. This fixes the bug
5895 reported by Tim Van Holder in:
5896 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
5897 Look for N_ as well as for _. Try to avoid matching #define for
5898 N_ and _.
5899 From Paul Eggert.
5901 2002-11-14 Akim Demaille <akim@epita.fr>
5903 * doc/autoconf.texi (C Compiler): Compiling several files at once.
5904 From Paul Eggert and Albert Chin-A-Young.
5906 2002-11-14 Akim Demaille <akim@epita.fr>
5908 * doc/autoconf.texi (C Compiler): Solitary backslashes.
5909 From Paul Eggert and Albert Chin-A-Young.
5911 2002-11-14 Kevin Ryde <user42@zip.com.au>
5913 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
5914 than assigning in main, to avoid HP cc +O3 optimizing it away.
5916 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
5918 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
5919 option. Process --recheck after parsing all options. Pass -q
5920 option to configure on --recheck.
5921 (AC_OUTPUT): Pass -q from configure to config.status.
5922 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
5923 arguments to record.
5924 * doc/autoconf.texi (config.status Invocation): Document
5925 config.status -q option.
5927 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
5929 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
5930 Makefile.in if Makefile.am exists.
5931 (output): Strip `.am' from Makefiles. Don't
5932 output AC_CONFIG_FILES if no Makefiles were found.
5934 2002-11-07 Akim Demaille <akim@epita.fr>
5936 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
5937 (local_updates): New.
5938 * Makefile.maint: Update, from CVS Bison.
5939 (local_updates): New.
5941 2002-11-06 Akim Demaille <akim@epita.fr>
5943 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
5944 declaration in extern "C" too.
5945 Reported by Roberto Bagnara.
5947 2002-11-06 Akim Demaille <akim@epita.fr>
5949 * tests/torture.at (Configuring subdirectories): Don't use grep
5950 -w.
5951 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
5952 Reported by Ezra Peisach.
5954 2002-11-05 Akim Demaille <akim@epita.fr>
5956 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
5957 Remove.
5958 We _have_ to stop using the old compatibility scheme that tried to
5959 avoid useless backslashes because Libtool 1.4.3 contains a
5960 AC_DEFINE([error_t], [int],
5961 [Define to a type to use for \`error_t' if it is not
5962 otherwise available.])
5963 We _have_ to quote the single quote and backslashes with \. The
5964 old compatibility scheme saw that ` was backslashed, and therefore
5965 did not quote the single quote. Hence before this patch, Autoconf
5966 was not compatible with Libtool.
5968 2002-11-04 Paul Eggert <eggert@twinsun.com>
5970 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
5971 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
5972 LC_NAME, LC_PAPER, LC_TELEPHONE.
5973 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
5975 2002-11-04 Akim Demaille <akim@epita.fr>
5977 Version 2.54c.
5979 * Makefile.maint (update, cvs-update, po-update, do-po-update):
5980 New.
5981 * config/texinfo.tex: Update.
5983 2002-11-03 Akim Demaille <akim@epita.fr>
5985 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
5986 from...
5987 (&autoreconf): here.
5988 ($help, $make, &parse_args, &autoreconf_current_directory):

6064 * tests/torture.at (Deep Package): New test.

6298 2002-10-22 Akim Demaille <akim@epita.fr>
6300 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

6304 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
6305 strings.
6307 2002-10-22 Akim Demaille <akim@epita.fr>
6309 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

6356 longer required can still cause errors.
6357 Reported by Alexandre Duret-Lutz.
6359 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
6360 to frozen files in @ARGV, as @ARGV must remain being a list of

6362 (&files_to_options): New function.
6363 (&freeze): Use &error.
6364 (&up_to_date): If a file that was included according to the cache
6365 is no longer there, then the output is out dated.
6366 (&main): Don't even check whether a file is up to date is anyway
6367 --force is given.
6368 * tests/tools.at (autom4te cache): New.
6370 2002-10-16 Akim Demaille <akim@epita.fr>

6377 that error messages can be easily located, and use GNU Make
6378 format, so that Emacs' compile mode understands us.
6379 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6380 if some file was changed instead of `print'.
6381 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

6415 file name to enable parallel executions.
6416 From Sam Varshavchik.
6418 2002-10-08 Akim Demaille <akim@epita.fr>
6420 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6421 aclocal invocation, as Gettext macros might not be visible to
6422 aclocal.
6423 Instead of blindly running autopoint, scan configure.ac (not the
6424 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6425 Reported by Paul D. Smith.
6427 2002-10-08 Paul Eggert <eggert@twinsun.com>
6429 Work around problems found when POSIXLY_CORRECT=1 is set.
6430 None of this seems to have anything to do with POSIX, really,
6431 but it's how Perl getopt works.
6432 * bin/autom4te.in (parse_args): Configure GetOpt with
6433 "permute", too.
6434 * doc/autoconf.texi (Invoking autom4te):
6435 --warning -> --warnings.

6457 * tests/torture.at (Configuring subdirectories): Be robust to
6458 users who use config.site to require for a cache: in this case,
6459 the two last configure runs, using two different sets of
6460 arguments, trigger a legitimate error.
6462 2002-09-28 Akim Demaille <akim@epita.fr>

6478 (tm_zone): Move their rules to...
6479 * lib/autoconf/types.m4: here, using AN_ macros.
6480 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
6481 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)

6488 2002-09-28 Akim Demaille <akim@epita.fr>
6490 * lib/autoconf/autoscan.m4: New file.
6491 * lib/autoconf/autoconf.m4: Include it.

6493 that were listed in the original autoscan.list.
6494 * lib/autoconf/headers.m4: Similarly with headers.
6495 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
6496 (.m4.m4f): Don't pass --prepend-include, since that's done by
6497 tests/autom4te itself.
6498 * lib/autoscan/Makefile.am: Include freeze.mk.
6499 (autoscan.list): New target --this file is no longer a source.
6500 (autoscan.pre): New file.
6502 2002-09-28 Akim Demaille <akim@epita.fr>
6504 * bin/autoscan.in (@kinds): Make them singular.
6505 Adjust all uses.
6506 (&init_tables): When --debug, report the list of rules to ease
6507 tracking changes in autoscan.list.
6508 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6510 2002-09-28 Akim Demaille <akim@epita.fr>
6512 * lib/autoscan/functions, lib/autoscan/headers,
6513 * lib/autoscan/identifiers, lib/autoscan/makevars,
6514 * lib/autoscan/programs: Merge into...
6515 * lib/autoscan/autoscan.list: this.
6516 * bin/autoscan.in (&init_tables): Adjust.
6518 2002-09-28 Akim Demaille <akim@epita.fr>
6520 * lib/autoscan/functions, lib/autoscan/headers,
6521 * lib/autoscan/identifiers, lib/autoscan/makevars,
6522 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
6523 `functions' line is now prefixed with `function:'.
6524 * bin/autoscan.in (&init_tables): Adjust.
6526 2002-09-28 Akim Demaille <akim@epita.fr>
6528 From now on, autoscan files must always map a macro name to a
6529 word: there is no `default' macro for autoscan.
6531 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6532 all.
6533 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6534 explicit.
6536 2002-09-28 Akim Demaille <akim@epita.fr>
6538 * bin/autoscan.in (%c_keywords): Remove.
6539 (&used): Keep only track of the words we might be interested in.
6540 (&output_kind): It is no longer needed to look for non active
6541 checks.
6543 2002-09-27 Akim Demaille <akim@epita.fr>
6545 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

6550 2002-09-27 Akim Demaille <akim@epita.fr>
6552 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
6553 from /tmp.
6554 Thanks to Bill Moseley and Paul Eggert.
6555 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
6556 the tmpdir must be created.
6557 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
6558 dir be in the build tree, instead of $TMPDIR.
6560 2002-09-27 Akim Demaille <akim@epita.fr>
6562 * bin/autoscan.in: Improve the comments.
6563 (&parse_args): Drop obsolete undocumented options.
6564 (&output_kind): Output warnings.
6565 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

6571 Reported by Ralf Corsepius.
6572 * doc/autoconf.texi (autoreconf Invocation): Likewise.
6574 2002-09-26 Akim Demaille <akim@epita.fr>
6576 Single suffix rules and seperated dependencies are not portable.
6578 * doc/autoconf.texi (Installation Directory Variables): Update.
6579 (Limitations of Make): Some about `Single Suffix Rules and
6580 Separated Dependencies'.
6581 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6582 (ifnames, autoscan, autom4te): Un-factor into several rules.
6584 2002-09-25 Paul Eggert <eggert@twinsun.com>
6586 * BUGS (Interoperability bugs): New section. Mention libtool
6587 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
6589 2002-09-24 Paul Eggert <eggert@twinsun.com>
6591 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
6592 make handles suffix-rules differently from GNU make.
6594 * bin/Makefile.am (SUFFIXES, .in): Remove.
6595 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
6596 Move the body of the old .in rule here.
6598 2002-09-16 Akim Demaille <akim@epita.fr>
6600 i960 compilers create `b.out' files by default.
6601 Reported by Ralf Corsepius.
6603 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
6604 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
6606 2002-09-13 Paul Eggert <eggert@twinsun.com>
6608 * doc/autoconf.texi (Particular Headers): Remove obsolete
6609 reference to `struct timezone' in the description of
6610 AC_HEADER_TIME.
6612 2002-09-13 Akim Demaille <akim@epita.fr>
6614 Version 2.54.
6616 * config/config.sub, config/config.guess: Update.
6617 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
6618 * Makefile.am: Adjust.
6620 2002-09-13 Akim Demaille <akim@epita.fr>
6622 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
6623 reading config.log when the compiler is rejected.
6624 Suggested by Guido Draheim.
6626 2002-09-13 Akim Demaille <akim@epita.fr>
6628 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6629 (chdir_init) might hang when stat'ing mounted directories.
6630 Reported by Vance Shipley.
6632 2002-09-12 Akim Demaille <akim@epita.fr>
6634 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6635 the lists.
6637 2002-09-12 Akim Demaille <akim@epita.fr>
6639 * doc/autoconf.texi (Defining Symbols): Present two different
6640 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
6641 difference between 1 argument calls, and 2-3 argument calls.
6643 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
6645 * doc/autoconf.texi: Review grammar and punctuation.
6647 2002-09-11 Paul Eggert <eggert@twinsun.com>
6649 * doc/autoconf.texi: Fix minor formatting, spelling, and
6650 grammatical typos.
6651 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6652 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6653 is obsolescent.
6655 2002-09-11 Akim Demaille <akim@epita.fr>
6657 * doc/autoconf.texi (Questions): Rename as...
6658 (FAQ): this.
6659 (Defining Directories): New.
6661 2002-09-09 Akim Demaille <akim@epita.fr>
6663 * doc/autoconf.texi (Making testsuite Scripts): Update.
6664 Suggested by Nishio Futoshi.
6666 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
6668 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
6669 plain `@' is wanted.
6671 2002-09-09 Akim Demaille <akim@epita.fr>
6673 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6674 `duplicates', since the algorithm was too naive and could keep
6675 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
6676 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6677 Reported by Ralf Corsepius.
6678 * tests/torture.at (Configuring subdirectories): Exercise these
6679 cases.
6681 2002-09-09 Akim Demaille <akim@epita.fr>
6683 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
6684 looking for a replacement file.
6685 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
6686 directory is relative.
6687 * doc/autoconf.texi (Generic Functions): Clarify the replacement
6688 directory definition.
6689 Reported by Andreas Schwab and Jim Meyering.
6691 2002-09-06 Akim Demaille <akim@epita.fr>
6693 * doc/autoconf.texi (Setting Output Variables): Clarify what
6694 precious variables are.
6695 Suggested by Pontus Skoeld.
6697 2002-09-05 Akim Demaille <akim@epita.fr>
6699 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6700 (ifnames, autoscan, autom4te): Since we don't only depend on
6701 configure.ac variables (such as VERSION etc.), but also on prefix
6702 and so forth, depend on Makefile, not configure.ac.
6703 Reported by Alexandre Duret-Lutz.
6704 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6706 2002-09-05 Kevin Ryde <user42@zip.com.au>
6708 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
6709 doesn't seem to be confined to ia64, just say "some versions".
6711 2002-09-04 Akim Demaille <akim@epita.fr>
6713 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
6714 Automake 1.6c.
6715 * Makefile.am (maintainer-clean-local): Remove.
6716 (MAINTAINERCLEANFILES): Remove COPYING.
6718 2002-09-03 Paul Eggert <eggert@twinsun.com>
6720 * doc/autoconf.texi (Configuration Commands): Remove obsolete
6721 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
6722 Brinkmann.
6724 2002-09-03 Akim Demaille <akim@epita.fr>
6726 * configure.ac: Bump to 2.53d.
6727 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
6728 as of today, on Automake's team suggestion.
6730 2002-09-03 Akim Demaille <akim@epita.fr>
6732 Version 2.53c.
6734 2002-09-02 Akim Demaille <akim@epita.fr>
6736 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
6737 SITE_MACRO_DIR.
6738 * configure.ac: Disable SITE_MACRO_DIR.
6740 2002-09-02 Jim Meyering <meyering@lucent.com>
6742 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
6743 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
6744 Also, tweak grammar: s/make sure to/be sure to/.
6746 2002-09-02 Paul Eggert <eggert@twinsun.com>
6748 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
6749 directory names are generally preferable to physical names.
6751 2002-09-02 Akim Demaille <akim@epita.fr>
6753 * lib/Autom4te/General.pm (&update_file): s/die/error/.
6754 Reported by Raja R. Harinath.
6755 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
6756 * bin/autoupdate.in: Use error instead of die.
6758 2002-09-01 Paul Eggert <eggert@twinsun.com>
6760 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
6761 ordinary shell concatenation rather than echo+tr+sed command that
6762 runs afoul of a long-line-related sed bug in Solaris 8.
6764 * bin/autoheader.in (parse_args): --warning -> --warnings.
6766 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
6767 stdout, as traditional "ls" does.
6768 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
6769 _AC_COMPILER_EXEEXT_O): Likewise.
6770 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
6772 * bin/autoconf.as: Add --prepend-include option. This patch was
6773 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
6774 but bin/autoconf.in is generated automatically from bin/autoconf.as.
6776 * bin/autoconf.in, configure: Regenerate.
6778 * doc/autoconf.texi (Special Shell Variables): Mention
6779 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
6781 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
6782 MAILPATH and set PS1, PS2, PS4 to default values, to work
6783 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
6784 For LC_ALL etc, first try to set to "C" as POSIX requires and as
6785 the Autoconf documentation specifies; fall back to "unset" only if
6786 this fails. Use a shell for-loop for this rather than an m4 loop,
6787 to shorten the output script.
6789 2002-08-30 Paul Eggert <eggert@twinsun.com>
6791 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
6792 1003.1-2001's requirements for CDPATH. Give a simpler workaround
6793 for the CDPATH problem. Document PWD.
6794 (Limitations of Builtins): Document the problem that "cd $foo" and
6795 "ls $foo" may refer to different directories in shells conforming
6796 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
6797 example, since the old example is now out of date.
6799 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
6800 FOO" and "ls FOO" talk about different directories; this catches
6801 problems when POSIX 1003.1-2001 "cd" fails due to symlink
6802 spaghetti.
6804 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
6805 of rolling our own unset.
6806 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
6807 in practice we needn't worry about CDPATH if unset doesn't work.
6809 * Makefile.in, aclocal.m4, bin/Makefile.in,
6810 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
6811 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
6812 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
6813 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
6814 tests/Makefile.in: Regenerate with Automake 1.6.3.
6816 * config/config.guess, config/config.sub, config/mkinstalldirs:
6817 Update.
6819 * configure: Regenerate with self.
6821 2002-08-30 Kevin Ryde <user42@zip.com.au>
6823 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
6824 default output.
6826 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
6828 * bin/autom4te.in (Request::load): Correctly test for "do" read
6829 failure.
6831 2002-08-29 Akim Demaille <akim@epita.fr>
6833 * lib/Autom4te/General.pm (&xqx): New.
6834 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
6835 hand, which is not portable.
6836 (&error): New.
6837 * bin/autom4te.in: Use them.
6838 Use &error instead of die.
6839 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
6840 Adjust.
6842 2002-08-17 Paul Eggert <eggert@twinsun.com>
6844 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
6845 default list of compilers to try, since it was long ago superseded
6846 by the ksh fc builtin. Suggested by Steven G. Johnson.
6848 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
6850 * doc/autoconf.texi (Invoking autom4te): End the option table,
6851 fixing a bug introduced by the previous patch.
6852 (Limitations of Make): Add a 'target lookup' subentry in the
6853 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
6855 2002-07-29 Mark D. Roth <roth@feep.net>
6857 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
6858 options and use $AUTOM4TE_PATH.
6859 * doc/autoconf.texi: Remove documentation of autom4te
6860 --include-envvar and --site-macro-subdir options and document
6861 use of $AUTOM4TE_PATH.
6862 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
6863 arguments from each language section.
6865 2002-07-29 Paul Eggert <eggert@twinsun.com>
6867 * doc/install.texi: Include copyright symbol in copyright notice.
6869 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
6870 Replace with:
6871 (AM_MAKEINFOFLAGS): New macro.
6872 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
6873 * Makefile.am (INSTALL): Use the new macros.
6874 Use -o rather than --output, since "missing" does not grok --output.
6876 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
6878 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
6879 comments do not always work. Never trust the exit status of
6880 `make -k'.
6882 2002-07-24 Kevin Ryde <user42@zip.com.au>
6884 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
6885 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
6887 2002-07-23 Paul Eggert <eggert@twinsun.com>
6889 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
6890 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
6891 apparently treats PATH="nonexistent" as if it contained ".".
6892 Bug reported by Stefan `Sec' Zehl.
6894 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
6896 * doc/autoconf.texi (Limitations of Make): Mention the special
6897 handling of the obj/ directory by BSD make.
6899 2002-07-20 Kevin Ryde <user42@zip.com.au>
6901 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
6902 backslashes.
6904 2002-07-19 Akim Demaille <akim@epita.fr>
6906 * doc/autoconf.texi (Function Portability): `exit'.
6907 (Programming in M4sh): Ethymology of M4sh.
6909 2002-07-19 Akim Demaille <akim@epita.fr>
6911 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
6913 2002-07-18 Akim Demaille <akim@epita.fr>
6915 Version 2.53b.
6917 2002-07-18 Akim Demaille <akim@epita.fr>
6919 * config/config.guess, config/config.sub: Update.
6921 2002-07-18 Akim Demaille <akim@epita.fr>
6923 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
6924 Automake's parts.
6926 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
6927 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
6928 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
6930 2002-07-18 Akim Demaille <akim@epita.fr>,
6931 Alexandre Duret-Lutz <duret_g@epita.fr>
6933 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
6934 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
6936 2002-07-17 Russ Allbery <rra@stanford.edu>
6938 * doc/autoconf.texi (Initializing configure): Clarify the
6939 description of the tarname default.
6941 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
6943 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
6944 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
6945 latter was not run.
6947 2002-07-17 Akim Demaille <akim@epita.fr>
6949 * lib/Autom4te/General.pm (find_file): Browse the directories in
6950 the order they are given.
6952 2002-07-17 Akim Demaille <akim@epita.fr>
6954 * tests/wrapsh.as, tests/wrappl.as: Merge into...
6955 * tests/wrapper.as: this.
6956 * tests/Makefile.am, configure.ac: Adjust.
6958 2002-07-17 Mark D. Roth <roth@feep.net>
6960 * configure.ac: Add --enable-site-macro-dir option.
6961 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
6962 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
6963 --site-macro-subdir options.
6964 * bin/autoconf.in: Add --prepend-include option.
6965 * bin/autoheader.in: Add --prepend-include option.
6966 * bin/autoreconf.in: Add --prepend-include option.
6967 * bin/autoscan.in: Add --prepend-include option.
6968 * bin/autoupdate.in: Add --prepend-include option.
6969 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
6970 macro directory, remove note that include path directories are
6971 used in reverse order, and document --prepend-include option.

7018 2002-06-27 Paul Eggert <eggert@twinsun.com>
7020 * config/install-sh: Quote $src. Prefer || to test's -o option,
7021 as per "Limitations of Builtins".
7022 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7023 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.

7053 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>

7056 of the cache should not depend on the name under which autom4te
7057 was installed.
7059 2002-06-07 Akim Demaille <akim@epita.fr>

7065 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7067 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7068 _AC_LANG_PROGRAM_C_F77_HOOKS.
7070 2002-06-07 Akim Demaille <akim@epita.fr>

7075 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
7076 AC_FUNC_FNMATCH_GNU.
7078 2002-06-07 Akim Demaille <akim@epita.fr>
7080 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7081 Rosetta Stone for Unix.
7083 2002-06-07 Akim Demaille <akim@epita.fr>
7085 * bin/autom4te.in (warn_forbidden): When rejecting a token,
7086 suggest m4_pattern_allow.
7087 Suggested by Adam J. Richter.
7089 2002-06-07 Akim Demaille <akim@epita.fr>
7091 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

7094 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

7107 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7108 if ln doesn't work.
7109 * NEWS: Likewise.
7110 * doc/autoconf.texi (Configuration Links): Likewise.

7148 version of Autoconf that is discussed.
7150 2002-05-22 Paul Eggert <eggert@twinsun.com>
7152 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7153 from the default list of compilers to try. Suggested by
7154 Kate Hedstrom.
7155 * NEWS: Document the above.
7156 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7158 2002-05-17 Paul Eggert <eggert@twinsun.com>
7160 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7161 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7162 This improves on an earlier suggestion by H. Peter Anvin.
7164 2002-05-16 Paul Eggert <eggert@twinsun.com>
7166 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7167 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7168 Both macros now accept an optional source-dir arg.
7169 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7171 * NEWS: Document this.
7172 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7174 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7175 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7176 not for GNU extensions; this undoes part of the 2000-11-03 change,
7177 reverting to 2.13-compatible behavior.
7178 Add new optional argument DIR.
7179 (AC_FUNC_FNMATCH_GNU): New macro.
7181 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7183 2002-05-08 Paul Eggert <eggert@twinsun.com>
7185 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7186 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7187 and it causes a 'test' syntax error if it fails.
7188 Bug reported by Stephen Gildea.
7190 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7191 If prototypes are supported, use them to check this at compile-time,
7192 instead of trying to check it at run-time. If we must do a run-time
7193 check, assume that setvbuf is standard when cross-compiling, as
7194 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7195 Bug reported by Paul D. Smith.
7197 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7198 argument specifying location of getloadavg.c. This removes a
7199 FIXME. This idea was taken from Jim Meyering's implementation in
7200 textutils.
7201 * doc/autoconf.texi (Particular Functions): Document this.
7202 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7203 that's what the code does; this fixes a bug reported by
7204 Paul D. Smith.
7206 2002-05-03 Akim Demaille <akim@epita.fr>
7208 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7209 autopoint instead of gettextize.
7210 ($uses_alocal): Rename as...
7211 ($uses_aclocal): this.
7212 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7213 Suggested by Bruno Haible.
7215 2002-05-03 Akim Demaille <akim@epita.fr>
7217 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7219 2002-04-29 Paul Eggert <eggert@twinsun.com>
7221 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7222 files to be 1 second older; just set them to be the same time.
7223 Also, sleep 1 second after the first aclocal, to work around
7224 problems with sub-second time stamps on the input files.
7226 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7228 * doc/autoconf.texi: Mention "set -e -x" lossage
7229 under node "Limitations of Builtins".
7231 2002-04-29 Akim Demaille <akim@epita.fr>
7233 * doc/install.texi: Better wording for setting variables when
7234 running configure.
7235 From Christian Cornelssen.
7237 2002-04-29 Akim Demaille <akim@epita.fr>
7239 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7240 of lack of $LINENO support, then the test will compare the $LINENO
7241 in testsuite vs. the lineno in the test file. This is wrong, of
7242 course.
7243 Be sure to protect it.
7244 Reported by Patrick Welche.
7246 2002-04-25 Akim Demaille <akim@epita.fr>
7248 * doc/autoconf.texi (Obsolete Macros): Typo.
7249 Reported by Vladimir Volovich.
7251 2002-04-25 Akim Demaille <akim@epita.fr>
7253 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7254 than some of the input files, hence, on the second run of aclocal,
7255 if some of its input are younger, make them older.
7256 Suggested by Paul Eggert.
7258 2002-04-25 Akim Demaille <akim@epita.fr>
7260 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7261 Thanks to Paul Eggert.
7263 2002-04-25 Akim Demaille <akim@epita.fr>
7265 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7266 and ac_subst_vars be sh variables containing the list of
7267 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7268 DEFAULT diversion.
7269 (_AC_INIT_PREPARE): Use them to log them.
7270 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7271 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7272 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7273 _AC_SUBST_FILES and _AC_SUBST_VARS.
7274 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7276 2002-04-24 Akim Demaille <akim@epita.fr>
7278 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7279 autoheader, so that automake does not complain about a missing
7280 config.h.in that was to be created.
7282 2002-04-23 Akim Demaille <akim@epita.fr>
7284 * bin/autoheader.in (parse_args): --warning takes an argument.
7285 Fixes PR/220.
7287 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7289 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

7300 2002-04-22 Akim Demaille <akim@epita.fr>
7302 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
7303 comma.
7304 Reported by Gregory Giannoni.
7306 2002-04-22 Akim Demaille <akim@epita.fr>
7308 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
7309 Fixes false failures on Darwin.

7334 Minor spelling and grammar fixes.
7336 * doc/autoconf.texi: Follow the outline suggested in the GNU
7337 Sample Texts sections of the Texinfo 4.2 manual. Most
7338 importantly, this makes sure that the copyright notices appear in
7339 all output formats. You probably need Texinfo 4.2 to generate
7340 the manual now.

7366 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7368 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

7395 * lib/autotest/general.m4 (AT_INIT): Likewise.
7396 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

7400 Use this M4sh to generate Autoconf's shell scripts.
7402 * tests/wrapsh.as: New, precursor of wrapsh.in.

7445 Don't use the KILL diversion, as it kills spurious output, which
7446 results in failures being hidden.

7457 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
7458 expanded if $# <= 2.
7460 * bin/autoreconf.in (autoreconf): Run automake after rerunning
7461 aclocal.
7463 2002-04-03 Akim Demaille <akim@epita.fr>
7465 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
7466 (_AC_COMPILER_EXEEXT_REJECT): New.
7467 Also recognize *.bb and *.bbg as compilation byproducts.
7468 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
7469 (_AC_COMPILER_OBJEXT): Use them.
7470 Fixes Debian #138666.
7472 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
7474 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
7476 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
7477 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
7478 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
7479 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
7480 (AC_C_CONST): Same.
7481 (AC_C_INLINE): Same.
7482 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
7483 * doc/autoconf.texi, NEWS: Document.
7484 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
7485 AC_C_CROSS.
7487 2002-04-02 Akim Demaille <akim@epita.fr>
7489 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
7490 _AS_MKDIR_P_PREPARE.
7492 2002-03-28 Kevin Ryde <user42@zip.com.au>
7494 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
7495 to avoid versions of HP C which don't allow that.
7497 2002-03-27 Paul Eggert <eggert@twinsun.com>
7499 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7500 (AS_SHELL_SANITIZE): Invoke it.
7501 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
7503 2002-03-26 Akim Demaille <akim@epita.fr>
7505 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
7507 2002-03-26 Akim Demaille <akim@epita.fr>
7509 * doc/autoconf.texi (Introduction): The GNATS base moved.
7511 2002-03-25 Paul Eggert <eggert@twinsun.com>
7513 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7514 as POSIX requires, as it doesn't work with Zsh.
7515 * doc/autoconf.texi (Assignments): Document the problem.
7517 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7519 * doc/autoconf.texi (Limitations of Make): Mention more issue
7520 about VPATH, overriding of macros in sub-makes, and handling of
7521 SHELL.
7523 2002-03-21 Paul Eggert <eggert@twinsun.com>
7525 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7526 problem with here-document buffer boundaries.
7528 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7529 when reinvoking the shell, to work around problems with installers
7530 who put strange things like "cd" commands in their environments.
7532 2002-03-19 Akim Demaille <akim@epita.fr>
7534 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
7535 From Aaron Ucko.
7537 2002-03-19 Akim Demaille <akim@epita.fr>
7539 * bin/autoscan.in (scan_file): Specify the location in `&used'
7540 invocations.
7541 From Nicolas Joly.
7543 2002-03-19 Akim Demaille <akim@epita.fr>
7545 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
7546 From Nishio Futoshi.
7548 2002-03-19 Akim Demaille <akim@epita.fr>
7550 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
7552 2002-03-18 Paul Eggert <eggert@twinsun.com>
7554 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7555 (Limitations of Usual Tools): Add mkdir section.
7557 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7558 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7559 back on AS_DIRNAME to compute prefixes otherwise; this is
7560 roughly what mkinstalldirs does. That way, we need not have
7561 our own filename disassembler. The old disassembler did not
7562 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7564 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7565 Create at_test_all by a series of assignments,
7566 not by a single assignment of a long string. The latter causes ksh
7567 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7568 presumably because of a buffer overrun.
7570 2002-03-14 Paul Eggert <eggert@twinsun.com>
7572 * lib/autotest/general.m4 (at_times_skip):
7573 Renamed from at_times. Now a boolean.
7574 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7575 says 'times: not found'.
7577 2002-03-14 Akim Demaille <akim@epita.fr>
7579 * bin/autoreconf.in (&study_gettextize): New.
7580 (&autoreconf): Handle newest gettextize.
7581 Rerun aclocal if needed.
7582 Suggested by Andreas Schwab.
7584 2002-03-13 Akim Demaille <akim@epita.fr>
7586 * doc/autoconf.texi (Special Shell Variables): More about IFS.
7588 2002-03-13 Akim Demaille <akim@epita.fr>
7590 * doc/autoconf.texi (Header Portability): New.
7591 Add information about stdint.h and inttypes.h from Paul Eggert.
7593 2002-03-13 Akim Demaille <akim@epita.fr>
7595 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
7596 -p'.
7597 From Bob Proulx.
7599 2002-03-12 Akim Demaille <akim@epita.fr>
7601 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
7602 m4_require.
7604 2002-03-11 Andreas Schwab <schwab@suse.de>
7606 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
7607 does not do it if --with-lispdir is given.
7609 2002-03-08 Akim Demaille <akim@epita.fr>
7611 Version 2.53.
7613 2002-03-08 Akim Demaille <akim@epita.fr>
7615 * doc/autoconf.texi (Subdirectories): Clarify that the
7616 subdirectory should exist.
7618 2002-03-08 Akim Demaille <akim@epita.fr>
7620 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
7622 2002-03-08 Akim Demaille <akim@epita.fr>
7624 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7625 aliases the actual variables, and modifications of the former
7626 affect the latter.
7628 2002-03-08 Akim Demaille <akim@epita.fr>
7630 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7631 because of C-c: have m4 output in tmp files, then mv them.
7633 2002-03-08 Akim Demaille <akim@epita.fr>
7635 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
7636 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
7637 * bin/ifnames.in: Copyright update.
7639 2002-03-08 Akim Demaille <akim@epita.fr>
7641 * doc/autoconf.texi (Invoking autom4te): New.
7643 2002-03-05 Akim Demaille <akim@epita.fr>
7645 * doc/autoconf.texi (Specifying Names): Clarification suggested by
7646 Kevin Ryde.
7648 2002-03-05 Akim Demaille <akim@epita.fr>
7650 Version 2.52i.
7652 2002-03-04 Akim Demaille <akim@epita.fr>
7654 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
7655 * lib/autoconf/general.m4 (AC_INIT): More informative error
7656 message for LIBOBJ.
7658 2002-03-04 Akim Demaille <akim@epita.fr>
7660 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
7661 parallel builds.
7663 2002-03-04 Akim Demaille <akim@epita.fr>
7665 * doc/autoconf.texi (Transforming Names): Equality between target
7666 and host is irrelevant.
7667 (Specifying Names, Canonicalizing): Remove all references to the
7668 backward compatibility hooks. Rather, collect them all into...
7669 (Hosts and Cross-Compilation): this new section.
7670 * doc/install.texi (System Type): Ditto.
7671 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7672 that `--host' implies cross-compilation.
7674 2002-03-04 Akim Demaille <akim@epita.fr>
7676 * doc/autoconf.texi (Evaluation Macros): New.
7677 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7678 useless.
7679 (_m4_foreach): Define the variant with immediate evaluation so
7680 that it contains exactly the items, not an expression which
7681 evaluation is the current item.
7682 (m4_re_string, m4_re_word): Don't over quote them.
7684 2002-03-04 Akim Demaille <akim@epita.fr>
7686 Instead of having stacking `shift's evaluated at the end, let
7687 `foreach' loops immediately evaluate them.
7689 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7690 $*. This is the n-th time I change my mind, but hopefully this is
7691 the last...
7692 (m4_lquote): New.
7693 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7694 efficient.
7695 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7696 it was only a hack for m4_text_wrap.
7697 (m4_car2): Remove, replaced by...
7698 (m4_cdr): New.
7699 (_m4_foreach): Adjust.
7700 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
7701 m4_bpatsubst for clarification.
7703 2002-03-04 Akim Demaille <akim@epita.fr>
7705 * doc/autoconf.texi (Changequote is Evil): New.
7707 2002-03-03 Kevin Ryde <user42@zip.com.au>
7709 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
7710 on old systems like SunOS.
7712 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
7714 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
7715 lib/autoconf/functions.m4, lib/autoconf/general.m4,

7723 message to be sent.
7725 2002-02-28 Kevin Ryde <user42@zip.com.au>

7729 2002-02-25 Akim Demaille <akim@epita.fr>
7731 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
7732 From Akinori Musha.
7734 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
7736 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
7737 translate \r\n to \n.
7739 2002-02-07 Akim Demaille <akim@epita.fr>
7741 Version 2.52h.
7743 2002-02-07 Akim Demaille <akim@epita.fr>
7745 Fix Autoconf PR/209.
7746 Also reported by Frank Denis.
7748 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
7750 2002-02-07 Akim Demaille <akim@epita.fr>
7752 Fix Autoconf PR/207:
7753 AC_PREFIX_PROGRAM fails with dashed program names
7755 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
7756 variable when looking for the prefix program.
7757 Now it also works for shell variables.
7759 2002-02-07 Akim Demaille <akim@epita.fr>
7761 * doc/autoconf.texi (Limitations of Builtins): More about
7762 case/esac.
7764 2002-02-06 Akim Demaille <akim@epita.fr>
7766 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
7767 case/esac, some shells don't support it.
7768 Reported by Zack Weinberg.
7769 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
7771 2002-02-06 Akim Demaille <akim@epita.fr>
7773 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
7774 sure not to introduce newlines in at_groups.
7775 * lib/autotest/Makefile.am (autotest.m4f): Typo.
7777 2002-02-06 Akim Demaille <akim@epita.fr>
7779 * tests/torture.at (Configuring subdirectories): Skip if aclocal
7780 is not available.
7782 2002-02-05 Paul Eggert <eggert@twinsun.com>
7784 * doc/autoconf.texi (Specific Compiler Characteristics):
7785 Describe HP-UX cc bug workaround more accurately.
7786 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
7787 not unsigned long.
7788 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
7789 cross-compilers, too. This undoes some of the most recent change
7790 to this file.
7792 2002-02-05 Akim Demaille <akim@epita.fr>
7794 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
7795 to make sure they are up to date when `check' is run.
7797 2002-02-05 Akim Demaille <akim@epita.fr>
7799 * doc/autoconf.texi (Making testsuite Scripts): Document
7800 package.m4.
7802 2002-02-05 Akim Demaille <akim@epita.fr>
7804 * lib/freeze.mk: New.
7806 2002-02-05 Akim Demaille <akim@epita.fr>
7808 Implement `autom4te --freeze'.
7810 * bin/autom4te.in (&freeze): New.
7811 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
7812 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
7814 2002-02-05 Akim Demaille <akim@epita.fr>
7816 * bin/autom4te.in (&parse_args): Implement `frozen files are
7817 optional are the sum of the previous files on the command line'.
7818 Also, pass `--reload-state=' on them, so...
7819 (handle_m4): don't.
7820 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
7821 (M4sh): Rely on M4sugar.
7822 (Autotest, M4sh, M4sugar): Use frozen files.
7824 2002-01-31 Akim Demaille <akim@epita.fr>
7826 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
7827 * doc/autoconf.texi (Initializing configure): Adjust.
7829 2002-01-30 Akim Demaille <akim@epita.fr>
7831 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
7832 alphanumeric to `-' instead of `_'.
7834 2002-01-30 Akim Demaille <akim@epita.fr>
7836 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
7837 for plain code, the other for cross-compilation code. The latter
7838 is now run with GCC only.
7839 * doc/autoconf.texi (Compilers and Preprocessors): New.
7841 2002-01-30 Akim Demaille <akim@epita.fr>
7843 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
7844 values.
7845 * doc/autoconf.texi (Initializing configure): Explain how to
7846 change AC_INIT default values.
7848 2002-01-29 Akim Demaille <akim@epita.fr>
7850 * tests/torture.at (Configuring subdirectories): Use configure.in,
7851 so that aclocal 1.4 works.
7852 Reported by Alexandre Duret-Lutz and Larry Schmitt.
7854 2002-01-28 Akim Demaille <akim@epita.fr>
7856 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
7857 needs an argument.
7859 2002-01-28 Akim Demaille <akim@epita.fr>
7861 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
7862 AUTOTEST_PATH *after* it was set.
7863 Don't put `.' in the PATH: the user should be precise and `./' if
7864 needed. In addition, given that the test suite does some `cd', if
7865 `.' is in the path, the `tested programs' sections will report
7866 programs found in the test suite's directory, while during the
7867 tests (performed in their own directory), these programs are no
7868 longer visible. In other words, the results is confusing and
7869 useless.
7870 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
7872 2002-01-24 Akim Demaille <akim@epita.fr>
7874 Version 2.52g.
7876 2002-01-24 Akim Demaille <akim@epita.fr>

7879 * doc/autoconf.texi: Finally add Akim as an author.
7881 2002-01-24 Akim Demaille <akim@epita.fr>
7883 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
7884 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
7885 Bourne. Use /bin/sh.
7886 From Andreas Buening.
7888 2002-01-24 Akim Demaille <akim@epita.fr>
7890 * config/config.guess, config/config.sub, config/texinfo.tex:

7899 * config/strip.m4: Remove, to ease sync'ing with any version of
7900 Automake.
7902 2002-01-24 Akim Demaille <akim@epita.fr>
7904 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
7905 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
7906 Reported by Geir Ove Myhr.
7908 2002-01-21 Akim Demaille <akim@epita.fr>
7910 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
7912 2002-01-21 Akim Demaille <akim@epita.fr>
7914 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
7915 message on invalid options.
7916 * bin/autom4te.in (parse_args): Don't use
7917 Autoconf::General::getopt with non valid options.
7919 2002-01-17 Jim Meyering <meyering@lucent.com>
7921 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
7922 $ac_cv_exeext so we don't use an old, invalid, cached value.
7924 2002-01-11 Akim Demaille <akim@epita.fr>
7926 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
7927 Meyering.
7928 * doc/autoconf.texi (Function Portability): Document the strnlen
7929 limitation.
7930 (Particular Functions): Document AC_FUNC_STRNLEN.
7931 * lib/autoscan/functions: Adjust.
7933 2002-01-06 Akim Demaille <akim@epita.fr>
7935 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
7936 package.m4, since is really depends upon configure.ac, not
7937 configure.
7938 * doc/autoconf.texi (testsuite Scripts): Adjust.
7939 * tests/Makefile.am (package.m4): New.
7940 EXTRA_DIST it since its a source.
7942 2002-01-06 Akim Demaille <akim@epita.fr>
7944 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
7945 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
7946 and PACKAGE_BUGREPORT from here...
7947 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
7948 arguments.
7949 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
7950 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
7951 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
7952 * tests/tools.at (autoheader): Adjust.
7953 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
7955 2002-01-06 Akim Demaille <akim@epita.fr>
7957 * bin/autoscan.in (scan_file): Use `&used'.
7959 2002-01-03 Akim Demaille <akim@epita.fr>
7961 * doc/autoconf.texi (Output): Improved wording regarding use of
7962 AC_OUTPUT.
7963 From Olly Betts.
7965 2001-12-18 Kevin Ryde <user42@zip.com.au>
7967 * doc/autoconf.texi (Function Portability): Add notes on sscanf
7968 sometimes needing writable input.
7970 2001-12-17 Jim Meyering <meyering@lucent.com>
7972 * doc/autoconf.texi (New Macros): Tweak wording.
7974 2001-12-14 Akim Demaille <akim@epita.fr>
7976 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
7977 trailing files, don't apply `-rf' to files which might not be
7978 created by configure (core, core.*, and *.core), but just `rm -f'.
7979 Suggested by Jonathan Kamens.
7981 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
7983 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
7985 2001-12-14 Akim Demaille <akim@epita.fr>
7987 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
7989 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
7991 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
7992 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
7993 abs_srcdir, top_srcpath to abs_top_srcdir.
7994 (_AC_OUTPUT_FILES): Adjust.
7995 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
7996 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
7997 * tests/wrappl.in, tests/wrapsh.in: Adjust.
7999 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8001 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8002 C/Fortran linking on HP/UX, by extracting the Fortran library
8003 search path from the LPATH line in the $F77 -v output.
8005 2001-12-12 Kevin Ryde <user42@zip.com.au>
8007 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8008 forbidden file descriptors table.
8010 2001-11-26 Akim Demaille <akim@epita.fr>
8012 * bin/autoscan.in (%c_keywords): Build it at top level.
8013 Map to 1 in order to simplify its uses.
8015 2001-11-26 Akim Demaille <akim@epita.fr>
8017 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8018 Remove $filepath, useless.
8019 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8020 variables, they are really part of the tokens.
8021 Split the input line on spaces and then look for tokens.
8022 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8023 because of `lex$U.$(OBJEXT)'.
8024 (&scan_files): Use "@list" instead of join.
8025 * doc/Makefile.am (CLEANFILES): Add *.fns.
8027 2001-11-26 Akim Demaille <akim@epita.fr>
8029 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8030 Remove, replaced by...
8031 * tests/wrappl.in: Be common for all the Perl executables.
8032 In particular autoscan and autoheader want -I.
8033 * configure.ac: Adjust.
8034 * lib/autoscan/headers: errno.h is portable.
8036 2001-11-26 Akim Demaille <akim@epita.fr>
8038 * bin/autoscan.in (used): New.
8039 Use it.
8041 2001-11-26 Akim Demaille <akim@epita.fr>
8043 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8044 directives.
8045 (&scan_sh_file): Remove a duplicate pattern.
8046 (&check_configure_ac): Use long options.
8047 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8049 2001-11-26 Akim Demaille <akim@epita.fr>
8051 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8052 Before, having a line containing the opening of a multi line
8053 comment made the whole line be ignored.
8055 2001-11-26 Akim Demaille <akim@epita.fr>
8057 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8058 (testsuite Scripts): Be one of its subsection.
8059 (Autotest Logs): New.
8061 2001-11-26 Akim Demaille <akim@epita.fr>
8063 Test groups are now run two directories deeper.
8065 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8066 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8067 at_top_builddir.
8068 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8069 top_srcdir, builddir and top_builddir.
8070 Use `at_*dir' relatively to the directory containing the
8071 suite, use `*dir' when relatively to the current group dir.
8073 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8075 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8076 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8077 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8078 spelling errors.
8080 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8082 * doc/autoconf.texi (Using System Type): Add an example of `case
8083 $host' usage so people quit using `case $target' everywhere.
8085 2001-11-22 Akim Demaille <akim@epita.fr>
8087 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8088 spotted by Jim Meyering.
8090 2001-11-16 Paul Eggert <eggert@twinsun.com>
8092 This patch implements a `long double' suggestion by Oliver Kiddle.
8094 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8095 static, to catch errors if the value isn't known at compile-time
8096 and the compiler supports dynamic arrays. Change its name from
8097 `_array_' to `test_array' to avoid potential name clashes.
8098 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8099 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8100 better than double. Catch a bug in GCC 2.95.2 x86.
8101 * doc/autoconf.texi (C Compiler): Document the above.
8102 * NEWS: Likewise.
8104 2001-11-13 Akim Demaille <akim@epita.fr>
8106 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8107 hand.
8108 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8110 2001-11-13 Akim Demaille <akim@epita.fr>
8112 * lib/autotest/general.m4 (AT_INIT): After having run the test
8113 group, go back to the initial directory, not to at_suite_dir.
8115 2001-11-13 Akim Demaille <akim@epita.fr>
8117 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8118 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8119 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8120 option.
8121 (AT_CHECK_CONFIGURE): Use absolute paths.
8122 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8123 The problem is still the old one: there is no means in M4 (that I
8124 know about) to create a defining macro, because there is no means
8125 to create `$1' etc., therefore, the defining macro ``swallows''
8126 all the arguments meant to the defined macro.
8128 2001-11-13 Akim Demaille <akim@epita.fr>
8130 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8131 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8132 configure.ac.
8133 * tests/aclocal.m4: Remove, as it is no longer used.
8135 2001-11-13 Akim Demaille <akim@epita.fr>
8137 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8138 variable names when referring to a single test group, or to
8139 `suite' when referring to the whole test suite.
8140 `at_last_test' is removed: m4 compute at_format itself.
8141 (at_stdout, at_stder1, at_stderr): New variables.
8142 (AT_CHECK): Use them.
8144 2001-11-13 Akim Demaille <akim@epita.fr>
8146 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8147 in PATH.
8148 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8149 Do it as soon as a test fails, don't wait till the end of the test
8150 suite.
8151 Don't remove $as_me.[0-9]*, since these files no longer exist.
8153 2001-11-13 Akim Demaille <akim@epita.fr>
8155 * tests/tools.at: Use absolute paths, since we are no longer run
8156 in place.
8158 2001-11-13 Akim Demaille <akim@epita.fr>
8160 Now that tests are running in their own private dir, there is no
8161 need to list the files to remove at the end of tests groups.
8163 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8164 (AT_data_files, at_data_files): Remove.
8165 (AT_CLEANUP, AT_DATA): Simplify.
8166 (AT_INIT): Adjust.
8167 Remove the group dir if !debug && !failed.
8168 * tests/atspecific.m4: Adjust.
8170 2001-11-13 Akim Demaille <akim@epita.fr>
8172 Start a new layout for Autotest: `testsuite' creates
8173 `testsuite.dir' in which the at-check-line etc. files are to be
8174 found, and `testsuite.dir/003' where the test group 3 is run.
8176 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8177 at_check_line_file, at_format, at_test_normalized, at_group_dir
8178 are new variables.
8179 Create the directories.
8180 Use absolute paths for at- files.
8181 (AT_CHECK): Adjust.
8183 2001-11-11 Michael Matz <matz@kde.org>
8185 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8186 (m4_car2): New.
8187 (m4_car): Properly quote arguments.
8189 2001-11-13 Akim Demaille <akim@epita.fr>
8191 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8192 with stricter rules on LIBOBJS.
8194 2001-11-12 Paul Eggert <eggert@twinsun.com>
8196 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8197 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8198 __PROTOTYPES too.
8200 2001-11-12 Akim Demaille <akim@epita.fr>
8202 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8204 2001-11-12 Akim Demaille <akim@epita.fr>
8206 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8207 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8208 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8209 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8210 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8211 specify to what the macro should be defined (typically to 1).
8213 2001-11-12 Akim Demaille <akim@epita.fr>
8215 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8216 From Jim Meyering.
8218 2001-11-12 Akim Demaille <akim@epita.fr>
8220 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8221 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8222 definition used by Automake where LEX is +/- "${missing} lex" and
8223 `missing' itself contains variables.
8225 2001-11-12 Akim Demaille <akim@epita.fr>
8227 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8228 Now that M4sh pushes BODY, the comments were output at the end of
8229 the test suites.
8231 2001-11-08 Akim Demaille <akim@epita.fr>
8233 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8234 that we can trace macros from aclocal.m4.
8235 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8236 obsoleted, and redirect to the former anyway.
8237 Reported by Ralf Corsepius.
8239 2001-11-08 Akim Demaille <akim@epita.fr>
8241 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8242 processed only if present.
8243 * tests/torture.at (Configuring subdirectories): Use autoreconf
8244 instead of successive calls to autoconf.
8245 Add a nonexistent subdirectory to exercise the patch above.
8246 Reported by Ralf Corsepius.
8248 2001-11-08 Kevin Ryde <user42@zip.com.au>
8250 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8251 doesn't accept .S files.
8253 2001-11-07 Akim Demaille <akim@epita.fr>
8255 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8256 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8257 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8258 * bin/autom4te.in (warn_forbidden): New.
8259 (handle_output): Use it.
8260 Read m4_pattern_forbid with messages.
8262 2001-11-05 Akim Demaille <akim@epita.fr>
8264 * bin/autom4te.in (--normalize): Remove.
8265 * lib/autom4te.in: Adjust.
8267 2001-11-05 Akim Demaille <akim@epita.fr>
8269 * tests/Makefile.am (testsuite): Rename this target as...
8270 ($(TESTSUITE)): this.
8271 From Nicolas Joly.
8273 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8275 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8276 the --prefix option, also remove it's argument.
8278 2001-11-05 Akim Demaille <akim@epita.fr>
8280 * doc/autoconf.texi (testsuite Invocation): Update.
8281 (Writing testsuite.at): Update.
8283 2001-11-03 Akim Demaille <akim@epita.fr>
8285 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8287 2001-11-03 Akim Demaille <akim@epita.fr>
8289 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8290 (&file_name_is_absolute): New, wrappers around routines from
8291 File::Spec.
8292 Use and export them.
8293 (&find_configure_ac): Optionally take a directory where to look at.
8294 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8295 the arguments.
8296 Default @ARGV to `.', not find_configure_ac.
8297 (&autoreconf): Argument is a directory.
8298 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8299 * doc/autoconf.texi (autoreconf Invocation): Update.
8301 2001-11-03 Akim Demaille <akim@epita.fr>
8303 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8304 (@export_forward_subs): New.
8305 Add basename, dirname, and fileparse.
8306 (@EXPORT): Adjust.
8307 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8308 Don't look for aclocal flags if we already know aclocal is not
8309 used.
8310 Move aclocal.m4t only if it exists.
8311 Reported by Ezra Peisach.
8313 2001-11-03 Akim Demaille <akim@epita.fr>
8315 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8316 passed on command line, defaulting to ./configure.ac if present.
8317 (&maybe_autoreconf, File::Find): Remove, unused.
8318 (&autoreconf): If autoconf is not used, don't try to trace.
8320 2001-11-02 Akim Demaille <akim@epita.fr>
8322 * configure.ac: Bump to 2.52g.
8324 2001-11-02 Akim Demaille <akim@epita.fr>
8326 Version 2.52f.
8328 2001-11-02 Akim Demaille <akim@epita.fr>
8330 * config/config.guess, config/config.sub, doc/standards.texi:
8331 * config/lispdir.m4: Update from masters.
8332 * configure.ac: Bump to 2.52f.
8334 2001-11-02 Akim Demaille <akim@epita.fr>
8336 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8337 Don't run aclocal when aclocal.m4 is not from aclocal.
8338 From Ezra Peisach.
8339 Don't run libtoolize and gettextize if --install is not given.
8341 2001-11-01 Paul Eggert <eggert@twinsun.com>
8343 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8344 be invoked before _AS_LINENO_PREPARE.
8345 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8346 than character ranges.
8348 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8349 invoking AS_BASENAME. Set the locale variables to 'C' if
8350 possible, as POSIX requires this to get the traditional
8351 behavior.
8352 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8354 2001-10-31 Paul Eggert <eggert@twinsun.com>
8356 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8357 with {}, as that triggers a bug in Bash 2.05.
8359 (_AS_LINENO_PREPARE): Use Sed rather than
8360 Awk. Fix the sed prepass to work even if there are multiple
8361 instances of $LINENO on the same line. Do not substitute for
8362 other variables like $LINENOT. Do not check file dates; such a
8363 check is unreliable on sufficiently fast machines, and removing
8364 the check makes the code simpler and more reliable. Check for
8365 output and chmod failures.
8367 * doc/autoconf.texi (Special Shell Variables): Document
8368 the above.
8370 2001-10-31 Akim Demaille <akim@epita.fr>
8372 * tests/Makefile.am (atconfig): Remove this target, Automake
8373 handles it now.
8375 2001-10-31 Akim Demaille <akim@epita.fr>
8377 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8378 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8379 provided, while it is optional.
8380 * configure.ac: Adjust.
8382 2001-10-26 Paul Eggert <eggert@twinsun.com>
8384 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8385 lib/Autom4te/Struct.pm:
8386 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8387 with 5.005_02.
8389 * doc/autoconf.texi (Special Shell Variables): Document some
8390 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8392 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8393 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8394 eval $LINENO is not portable in practice.
8396 2001-10-24 Akim Demaille <akim@epita.fr>
8398 * lib/Autom4te/General.pm (backname): New.
8400 2001-10-24 Akim Demaille <akim@epita.fr>
8402 * m4/: Remove, merged into...
8403 * config/: here.
8405 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8407 * doc/autoconf.texi (Shellology): Mention the problems with bash
8408 2.05's use of ANSI quoting in its `set' builtin.
8410 2001-10-22 Paul Eggert <eggert@twinsun.com>
8412 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8413 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8414 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8415 POSIX decided to standardize on the int flavor of strerror_r.
8416 Always do char* test, as there's no reason not to.
8417 Assign to a char* var, to catch strerror_r that returns int*.
8419 * doc/autoconf.texi (Particular Functions):
8420 Document the above changes. Also, document the fact that
8421 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8423 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8425 2001-10-20 Akim Demaille <akim@epita.fr>
8427 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
8428 the executable was missing from the log.
8430 2001-10-20 Akim Demaille <akim@epita.fr>
8432 * lib/Autom4te/General.pm (&update_file): If destination is
8433 unchanged, remove the source.
8434 (&up_to_date_p): Don't be verbose, be debug.
8435 * bin/autoreconf.in: No longer support --m4dir.
8436 (&autoreconf): Display the full path of the configure.ac we are
8437 studying.
8438 Trace it only once.
8439 Be sure to honor --force with gettextize.
8440 Always run aclocal.
8441 * doc/autoconf.texi: Adjust.
8443 2001-10-20 Akim Demaille <akim@epita.fr>
8445 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8446 Remove, dead.
8447 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8448 `intl' is already present, as it refuses unless --force.
8449 (&parse_args): Use -I, --include instead of the old Autoconf
8450 options.
8451 ($localdir, $autoconf_dir): Remove.
8452 (@include): New.

8761 * tests/fortran.at (GNU Fortran 77): there.
8762 * doc/autoconf.texi (autoconf Invocation): Fix the example:
8763 AC_TRY_RUN is about compilation, not shell commands.

8921 arguments. Fixed a typo.
8923 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8925 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
8926 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
8928 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8930 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
8931 * bin/autoupdate.in: Ditto.
8932 * bin/autoheader.in: Reworded a few comments.
8933 * bin/autoconf.in: Reworded help text for a few options.
8934 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
8935 * bin/autoscan.in, bin/autoupdate.in: Ditto.
8937 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8939 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
8940 already have $file). Set output files to binary mode (helps avoid
8941 CR issues on DOSish systems).
8943 2001-09-19 Akim Demaille <akim@epita.fr>
8945 * lib/autotest/general.m4: Englishoes.
8946 From Tim Van Holder and Alexey Mahotkin.
8948 2001-09-18 Paul Eggert <eggert@twinsun.com>
8950 * doc/autoconf.texi (Common Shell Constructs): New node,
8951 documenting AS_DIRNAME.
8952 (Limitations of Usual Tools): Refer to it when discussing dirname.
8953 Also, update discussion of POSIX standard to reflect latest draft.
8955 * lib/autoconf/c.m4:
8956 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
8958 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8959 Do not pass a first argument with leading '-'
8960 to expr, by parenthesizing initial integers that might be negative.
8962 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
8963 now merely checks whether it is an error to pass an argument
8964 to getpgrp.
8966 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
8967 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
8968 whether it is a (compile-time) error to pass an argument to
8969 getpgrp. This simpler test supports the revised documentation,
8970 and is all that AC_FUNC_GETPGRP's users really need.
8972 2001-09-18 Akim Demaille <akim@epita.fr>
8974 * doc/autoconf.texi (Limitations of Make) <$<>: New.
8976 2001-09-18 Akim Demaille <akim@epita.fr>

8979 `{}'.
8980 * lib/autotest/general.m4 (AT_INIT): Adjust.
8982 2001-09-18 Paul Wagland <paul@wagland.net>
8984 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
8985 correctly.
8986 Add test for AS_BASENAME.
8987 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
8988 added test. It now correctly handles /1/2/3/, returning '3' not ''.
8989 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
8990 * tests/base.at: Fixed the expected responses. The old ones were
8991 one line out...
8992 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
8993 the documentation claims it should (and how it behaved in 2.13).
8995 2001-09-18 Akim Demaille <akim@epita.fr>
8997 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
8998 the AC_CONFIG_COMMANDS invocation.
8999 This also solves the name clash problems.
9000 Don't set the package's ID.
9001 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9002 No longer to be shipped.
9003 (version.in): Remove.
9004 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9005 * lib/autoconf/status.m4: Adjust.
9006 Use `m4_PACKAGE_STRING'.
9007 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9008 the only optional argument is the name of the test suite.
9009 Expect `package.m4' to define the package signature.
9010 * lib/autom4te.in (Autotest): Add `package.m4?'.
9011 * tests/Makefile.am (package.m4): New.
9012 * tests/suite.at: ifnames is a victim.
9014 2001-09-18 Akim Demaille <akim@epita.fr>
9016 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9017 AC_LIBSOURCE, AC_CONFIG_FILES.
9018 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9019 program version string doesn't match the package's.
9020 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9021 after `(cached)'.
9023 2001-09-17 Paul Eggert <eggert@twinsun.com>
9025 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9026 Allow expression to return any value that can fit into unsigned long
9027 (not int, as before). Check for output errors.
9029 2001-09-17 Bruno Haible <haible@ilog.fr>
9031 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9032 Always include <stdio.h> and <stdlib.h>. Evaluate
9033 the expression in an extra function before these includes. Call
9034 fprintf "%d" only after ensuring the argument is of type 'int'.
9035 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9037 2001-09-17 Paul Eggert <eggert@twinsun.com>
9039 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9040 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9041 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9042 when they don't exist.
9044 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9045 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9046 need it.
9048 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9049 version with the version used by fileutils 4.1, except use
9050 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9051 we don't need it.
9053 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9055 2001-09-13 Akim Demaille <akim@epita.fr>
9057 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
9058 _first_.
9059 Reported by Gerrit P. Haase.
9061 2001-09-13 Akim Demaille <akim@epita.fr>
9063 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9079 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
9080 Likewise.
9081 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
9082 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
9083 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
9084 AT_tests_all for consistency.
9085 Set at_victims.
9086 (AT_VICTIMS): Similar to AT_KEYWORDS.
9087 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
9089 2001-09-13 Akim Demaille <akim@epita.fr>
9091 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9093 2001-09-13 Akim Demaille <akim@epita.fr>
9095 * lib/autotest/general.m4 (AT_INIT): Create and remove
9096 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9097 test suites can cohabit.
9099 2001-09-13 Akim Demaille <akim@epita.fr>
9101 * tests/mktests.sh: Don't output banners for empty test files.
9103 2001-09-13 Akim Demaille <akim@epita.fr>
9105 Test suites can be run independently of configure.

9153 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

9156 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

9169 2001-09-07 Akim Demaille <akim@epita.fr>

9174 related variables into `at_package_*'.

9184 Move toward possibly stand-alone test suites.
9186 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
9187 in addition, it introduces useless differences in logs.

9189 Adjust PATH computation.
9190 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

9200 to avoid GCC warnings.
9201 From Uwe Seimet.
9203 2001-09-05 Akim Demaille <akim@epita.fr>

9207 2001-09-05 Akim Demaille <akim@epita.fr>
9209 Be ready to handle filenames as stupid as `dnl.at', for if even
9210 the maintainer is dumb enough to do that...
9212 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9213 excellence in M4 quotation: consider `__file__' is active.
9215 And BTW, when invoking m4, pass the --include in the right order:
9216 the wrong one.
9218 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

9246 New, extracted from main.
9247 Use IO::File wherever possible.
9248 (input.m4): Be constant, use -I instead of hard coding $tmp.

9281 (testsuite Scripts): There is no such thing as `atconfig.in'.

9284 2001-08-31 Akim Demaille <akim@epita.fr>
9286 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9287 inverse order.

9292 to m4sugar was lacking!
9294 2001-08-31 Akim Demaille <akim@epita.fr>
9296 * man/Makefile.am (.x.1): We really have to pass
9297 autom4te_perllibdir.
9299 2001-08-31 Akim Demaille <akim@epita.fr>
9301 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

9303 run is stupid.
9305 2001-08-31 Akim Demaille <akim@epita.fr>
9307 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9308 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9309 Use directly autom4te, not autoconf.

9333 `print $out' doesn't print `$_' but `$out'.
9334 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9335 (autoheader): Pass --force since the test suite goes too fast for
9336 the time stamps.
9337 Adjust to the new autoheader messages.
9339 2001-08-31 Akim Demaille <akim@epita.fr>

9365 Forward autom4te's options instead of interpreting them.

9382 2001-08-31 Akim Demaille <akim@epita.fr>

9385 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9386 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9387 installed peer executables, only PATH is allowed to resolve it.
9388 Pass `autoconf_dir' via options, not via invisible envvars.
9389 * lib/Autom4te/General.pm (&find_peer): Remove.
9390 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9391 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9392 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9393 find the executables for it.
9394 * tests/Makefile.am: Major cleanup. Too lazy to document...
9395 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9396 We only need PERL.
9397 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9398 indeed related to running the test suite, while passing
9399 --autoconf-dir and others is related to running non installed
9400 Autoconf executables. So don't do that, leave it to...
9401 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9402 * tests/autoscan: New.
9403 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
9404 refer to library files: rely on --language.

9422 2001-08-29 Akim Demaille <akim@epita.fr>

9427 2001-08-29 Akim Demaille <akim@epita.fr>
9429 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

9490 * lib/autotest/general.m4 (AT_INIT): Log the command line.

9599 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
9600 the name of the directory they're in, instead of the filename,
9601 since version.m4 is now in m4sugar, but m4_acversion must not be
9602 classified as an Autoconf macro.
9603 ($input_m4): Don't qualify the path to m4sugar.
9604 Rather, pass autoconf_dir to m4.
9605 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

9693 2001-08-20 Akim Demaille <akim@epita.fr>

9742 2001-08-20 Akim Demaille <akim@epita.fr>

9811 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

9889 autom4te.cache (it's a directory, not a file.
9890 * Makefile.am: Ditto (but maintainer-clean-local).
9892 2001-08-15 Akim Demaille <akim@epita.fr>
9894 * bin/autom4te.in (@m4_warning): New.
9895 (&handle_m4): Use it.
9896 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

9901 2001-08-15 Akim Demaille <akim@epita.fr>

9966 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9968 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
9969 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
9970 * doc/autoconf.texi (C Compiler Characteristics): Update
9971 documentation for AC_C_BIGENDIAN.
9973 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9975 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
9976 magic values from an object file when cross-compiling.
9977 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
9979 2001-08-10 Akim Demaille <akim@epita.fr>
9981 * bin/autom4te.in (&handle_output): Don't use `grep' with side
9982 effects.
9983 Suggested by Russ Allbery.
9985 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
9987 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
9988 current $prefix to the sub-configures.
9990 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
9992 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
9993 extension (needed on BeOS). Reported by Guido van Rossum.
9995 2001-08-09 Akim Demaille <akim@epita.fr>
9997 * bin/autom4te.in ($icache): Load it only if older than autom4te.
9999 2001-08-07 Akim Demaille <akim@epita.fr>
10001 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10002 removed.
10003 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10004 No need to remove the files before and after the each test, before
10005 each test and at the end of the suite is enough.
10006 Display only the children `times', not the shell's.
10007 If the test failed or was skipped, at-times is not available.
10009 2001-08-07 Akim Demaille <akim@epita.fr>
10011 Always produce testsuite.log, including when there are no
10012 failures. This helps getting information on skipped tests, and
10013 duration of the tests. Err, implement the latter btw.
10015 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10016 Dump information on the first run of each test.
10017 (AT_CLEANUP): Create `at-times' containing the duration of the
10018 test group.
10020 2001-08-07 Akim Demaille <akim@epita.fr>
10022 The use of `dumpstat' revealed that `len' was used although it
10023 should not. m4_text_wrap was using it, but in the Autoconf world
10024 where it is legal. Hence (i) test M4sh in its own world, not
10025 Autoconf's, and (ii), ahem, fix the bug :)
10027 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10028 does not like `' instead of [].
10029 (AT_INIT): Forbid `^_?AT_'.
10030 And don't output such tokens.
10031 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10032 `script.as', and `autom4te.cache'.
10033 Remove `empty' and `macro' which are no longer used.
10034 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10035 * tests/m4sugar.at: Use it.
10036 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10038 2001-08-07 Akim Demaille <akim@epita.fr>
10040 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10042 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10044 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10046 2001-08-04 Akim Demaille <akim@epita.fr>
10048 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10049 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10050 AC_TRY_LINK.
10051 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10052 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10053 (AC_F77_MAIN): Likewise.
10055 2001-08-04 Akim Demaille <akim@epita.fr>
10057 Don't rely on M4sugar outputting the patterns in files, since we
10058 might process the output _without_ running m4, hence without these
10059 files.
10061 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10062 * bin/autom4te.in (@Request::includes): Remove, unused.
10063 (@Request::source): Rename as...
10064 (@Request::input): this.
10065 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10066 (&handle_output): Fetch the patterns from the traces.
10067 `$forbidden' and `$allowed' are constant: use m//o.
10068 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10069 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10071 2001-08-04 Akim Demaille <akim@epita.fr>
10073 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10074 autoconf', i.e., in addition to caching traces, cache the output.
10076 * bin/autom4te.in (Request::cache): Rename as...
10077 (Request::id): this.
10078 ($cache, $icache, $tcache, $ocache): New.
10079 (&handle_m4): Save M4 output in the cache instead of $tmp.
10080 (&handle_output): Adjust.
10081 (&up_to_date_p): Check that the output cache is up to date too.
10082 (top level): Run `&handle_m4' iff force or the cache is invalid.
10083 Run `&handle_output' if the output cache is more recent.
10085 2001-08-04 Akim Demaille <akim@epita.fr>
10087 * bin/autom4te.in ($force): New.
10088 (&parse_args, &print_usage): -f, --force is a new option.
10089 (&handle_output): CPP directives might have spaces after `#'.
10090 (&parse_args): The first file only can be frozen.
10092 2001-08-04 Akim Demaille <akim@epita.fr>
10094 Don't let autom4te compute the `include' traces several times:
10095 first check that the trace cache file is up to date, and then
10096 compare its timestamp with that of the output.
10098 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10099 the preamble. Don't require 5.005 as Autom4te::General does it,
10100 and better yet (use `use', not `require'!).
10101 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10102 Class::Struct as Autom4te::Struct.
10103 * lib/Autom4te/General.pm (File::stat): Use it.
10104 (&mtime): New, export it.
10105 * bin/autom4te.in: Use it.
10106 Declare `$req' is invalid if it is outdated.
10107 Don't declare it valid before saving it if something went wrong.
10109 2001-08-04 Akim Demaille <akim@epita.fr>
10111 Autom4te shall not encode Autoconf data, and preselecting traces
10112 must be proposed to the users.
10114 * bin/autom4te.in (@required_trace): Remove.
10115 (@preselect): New.
10116 (&parse_args, &print_usage): -p, --preselect is a new option.
10117 (&up_to_date_p): Adjust.
10118 * bin/autoconf.in: Preselect some Autoconf macros.
10120 2001-08-04 Akim Demaille <akim@epita.fr>
10122 * tests/tools.at (autoconf --trace: user macros): Check traces on
10123 macros invoked without arguments, and macros invoked with multiple
10124 lines arguments.
10126 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10128 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10129 arguments.
10131 2001-08-03 Akim Demaille <akim@epita.fr>
10133 * bin/autoconf.in ($@): Work around the usual sh bug.
10134 From Nicolas Joly.
10136 2001-08-03 Akim Demaille <akim@epita.fr>
10138 Clean up the handling of the M4 builtins tracing exception.
10140 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10141 trace requests.
10142 (@m4_builtins): Rename as...
10143 (@m4_builtin): this.
10144 (%m4_builtin_alternate_name): New.
10145 (&parse_args): Complete the trace requests with alternate names.
10146 (&handle_traces): Hence no longer do it here.
10147 (&trace_requests): Remove, unused.
10149 2001-08-03 Akim Demaille <akim@epita.fr>
10151 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10152 m4_if, and m4_wrap.
10154 2001-08-03 Akim Demaille <akim@epita.fr>
10156 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10157 (m4_divert_pop): Dump the whole diversion stack when a diversion
10158 mismatch happens.
10159 * bin/autom4te.in (&handle_output): Remember of the first
10160 occurrence of a possibly undefined macro, not the last.
10161 Complain about the possibly undefined macros in the same order as
10162 the appear in the output.
10163 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
10164 * tests/tools.at (autoconf: forbidden tokens, basic)
10165 (autoconf: forbidden tokens, exceptions): No longer sort
10166 autoconf's stderr, as it is now deterministic.
10167 Check that `dnl' is caught.
10169 2001-08-01 Akim Demaille <akim@epita.fr>
10171 * configure.ac: Bump to 2.52c.
10173 2001-08-01 Akim Demaille <akim@epita.fr>

10186 `die'.
10187 (&END): New.
10188 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
10189 `END', as `Autom4te::General::END' will be triggered.
10190 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
10191 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

10583 compiler, not the preprocessor.

10626 cross-language link tests can be performed successfully.
10627 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
10628 after $LIBS, for consistency; this should be the general rule since

10635 at-stdout and at-stderr instead of removing the newline
10636 from the echo output, which is not guaranteed to work.

10704 * doc/autoconf.texi (Redefined M4 Macros): New.
10706 2001-06-23 Akim Demaille <akim@epita.fr>
10708 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider

10747 ./configure --program-suffix=foo produces `transform=s,$$,foo,;',
10748 but some sed choke on multiple `;', and other tools (e.g.,
10749 Automake), include the separator themselves.
10751 * acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
