3 * NEWS: Warnings are now generated by default for unknown
4 --enable-* and --with-* options.
5 * doc/autoconf.texi (Option Checking): Renamed from
6 (Configure Option Checking). Tighten up the wording a bit.
7 (External Software, Package Options): Cross-reference to Option
8 Checking, and use this to shorten our section.
9 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
10 "$x" to test "x$foo" != x.
11 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
12 Don't warn if $enable_option_checking is "no".
13 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
14 ac_unrecognized_opts to the empty string.
15 Don't echo the unrecognized opts, as this might mishandle
16 backslashes or leading -.
17 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
18 usage next to the other --disable-FEATURE options in the
19 help string.
21 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
23 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
24 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
25 Print warning for unrecognized --with and --enable options
26 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
27 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
28 Disable option checking when subdirs are configured.
29 (AC_OUTPUT): If warnings are enabled, print warning about
30 unrecognized --with and --enable options at the end of
31 the configure output (as well as at the beginning).
32 * doc/autoconf.texi (Option Checking): New node.
33 Document new option warning functionality.
35 2006-12-16 Eric Blake <ebb9@byu.net>
37 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
38 * NEWS: Start news for current version.
40 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
42 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
43 Define HAVE_GETMNTENT to 1, not to the empty string.
44 Problem originally reported by Jochen Friedrich in
45 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
47 This change prompted by a problem report by Andrey Simonenko in
48 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
49 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
50 object-like macros only, in the traditional portable character
51 set.
52 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
53 Warn about attempts to define things that are not identifiers.
54 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
55 awful hack that AC_DEFINEd macro names containing parentheses.
57 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
59 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
60 too drastic, even if Texinfo in theory requires it for info mode.
62 (config.status Invocation): Renamed back from Recreating a
63 Configuration).
64 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
65 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
67 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
69 * NEWS: Version 2.61a.
71 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
72 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
74 * NEWS: Document changes with echo and printf, and the lack
75 of limits on the total size of multi-line values of substituted
76 variables, and the AC_FUNC_FSEEKO fix.
78 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
80 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
81 Writing configure.ac.
82 (Autoconf Input Layout): Renamed from configure.ac Layout.
83 (Recreating a Configuration): Renamed from config.status Invocation.
84 (Obsolete Recreation): Renamed from Obsolete config.status Use.
85 (acconfig Header): Renamed from acconfig.h.
86 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
87 (Writing Testsuites): Renamed from Writing testsuite.at.
88 (Autom4te Cache): Renamed from autom4te.cache.
90 * BUGS: Remove mention of VPATH problem, since it's now documented
91 not to be a bug in the Autoconf build procedure itself, but rather
92 a problem with the proprietary `make' programs.
94 * doc/autoconf.texi (Build Directories): Add a cross reference
95 to VPATH and Make.
97 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
98 * doc/standards.texi: Sync from gnulib.
100 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
101 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
102 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
103 generated automatically.
105 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
107 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
108 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
109 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
111 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
113 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
114 `CEOF$ac_eof' special marker, the awk script cannot contain a
115 line matching `^CEOF', so this is not needed any more.
116 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
117 special marker in the test.
119 2006-12-06 Stepan Kasal <kasal@ucw.cz>
121 * tests/tools.at (autom4te preselections): Use `find -newer';
122 remove one of the sleeps.
124 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
125 more readable, using ...
126 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
128 * doc/autoconf.texi (autoheader Invocation): Do not double-
129 quote the parameter of `AH_BOTTOM' in the example.
131 2006-12-05 Stepan Kasal <kasal@ucw.cz>
133 * doc/autoconf.texi (Configuration Headers): Remove the
134 example with multiple input files.
135 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
136 multiple input files.
138 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
140 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
141 creating the awk substitution script, handle one input line at a
142 time, so that the maximum length of a substituted (multi-line)
143 value is not limited by the size of the sed pattern space.
144 The trade-off is a slightly repetitive sed script.
145 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
146 can only have up to 7 characters, due to Solaris 10 /bin/sed.
147 * tests/torture.at (Substitute a 2000-byte string): Increase the
148 test with several long lines, they should not be caught by sed
149 limits any more.
151 * tests/tools.at (autom4te preselections): New test, to flag
152 entries missing from autom4te.cfg.
153 Report by David Byron <dbyron@hheld.com>.
155 * tests/torture.at (Substitute a 2000-byte string): Actually use
156 AC_PROG_AWK, so the last change works as intended.
157 (Substitute and define special characters): Likewise.
158 (Substitute a newline): Likewise.
160 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
161 instead of `awk' consistently.
162 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
163 * tests/torture.at (Torturing config.status): Test both the
164 result of AC_PROG_AWK and plain awk.
165 (Substitute a 2000-byte string): Likewise.
166 (Substitute and define special characters): Likewise.
167 (Substitute a newline): Likewise.
169 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
171 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
172 can be assigned to a function pointer. Problem reported by
173 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
174 part of a patch by Ralf Wildenhues in that same bug report.
176 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
178 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
179 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
181 2006-12-01 Eric Blake <ebb9@byu.net>
183 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
184 cross-compiling from cygwin to mingw.
185 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
186 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
187 to lib/autoconf/c.m4.
189 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
191 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
192 string for more reliable failure. Wrap the entire test that
193 causes the broken Solaris printf to dump core, in a subshell,
194 so the segmentation fault message is reliably suppressed.
195 Fix shell expansion errors by using /usr/ucb/echo always;
196 avoid an error on systems without it by another subshell.
197 Avoid m4 expansion of `$1'. Set the zeroth argument of the
198 subshell-$as_echo to `as_echo', for better error message.
200 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
202 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
203 `BASH_SOURCE' contain a newline, set them to empty, as they may
204 not be unset.
206 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
208 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
209 years and is too hard to maintain now. The last straw was
210 reported by Jerker Baeck in
211 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
212 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
213 * doc/autoconf.texi (Particular Functions): Move
214 AC_FUNC_SETVBUF_REVERSED from here...
215 (Obsolete Macros): ... to here. Say that it does nothing now.
216 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
217 Turn into (almost) a no-op.
219 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
220 (AC_C_VOLATILE):
221 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
222 These macros are obsolescent and new applications shouldn't need them.
223 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
224 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
225 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
226 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
227 (AC_FUNC_VPRINTF): Likewise.
228 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
229 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
230 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
232 * doc/autoconf.texi (Setting Output Variables): Mention that
233 @VAR1@VAR2 has unspecified behavior. Problem reported by
234 Ralf Wildenhues.
235 * NEWS: Mention this.
237 * Makefile.am: Put only a single '#' into the copyright notice,
238 so that it's also present in the output file. Standardize wording
239 in makefile copyright notices to match GNU coding standards.
240 * bin/Makefile.am: Likewise.
241 * doc/Makefile.am: Likewise.
242 * lib/Makefile.am: Likewise.
243 * lib/freeze.mk: Likewise.
244 * lib/autoconf/Makefile.am: Likewise.
245 * lib/autoscan/Makefile.am: Likewise.
246 * lib/autotest/Makefile.am: Likewise.
247 * lib/m4sugar/Makefile.am: Likewise.
248 * man/Makefile.am: Likewise.
249 * tests/Makefile.am: Likewise.
250 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
251 one-line file.
253 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
255 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
256 in the sed script that mangles the awk script: delete up to the
257 first exclamation mark only.
258 * tests/torture.at (Substitute and define special characters):
259 Test '!' too.
261 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
263 Rewrite config files generation: avoid quadratic growth in
264 the number of substituted variables by using awk instead of sed
265 for the bulk of the substitutions.
266 * NEWS: Mention this.
267 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
268 forbidden in the output (and thus input) file.
269 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
270 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
271 generate just one large awk script for substitutions,
272 eliminating much of the earlier complexity, while adding some
273 new complexity. Only expand the substitution templates at
274 configure time, for smaller configure script size. If
275 _AC_SUBST_FILES are used, test 'awk' for working getline support
276 at config.status time. If absent, interpolate through the
277 shell. The awk script was written with much help
278 from Paolo Bonzini and Paul Eggert.
279 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
280 (_AC_SED_FRAG_NUM): Likewise.
281 (_AC_SUBST_CMDS): Renamed from...
282 (_AC_SED_CMDS): ...this.
283 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
284 * tests/torture.at (Substitute a 2000-byte string): Also
285 substitute a line with 1000 words, and a variable with several
286 long lines.
287 (Substitute and define special characters): Test awk special
288 characters, and put substitution input strings `@foo@' in the
289 output, to test that no recursion happens; test several other
290 combinations from Paolo Bonzini.
292 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
294 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
295 that replaced echo with AS_ECHO where this wasn't necessary.
296 Problem reportd by Ralf Wildenhues.
297 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
298 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
299 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
301 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
303 * lib/freeze.mk (GREP): Removed, no need to initialize this.
305 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
307 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
308 that traditional Awk lacks 3-arg "split". It has it.
309 Mention that FS must be a single character, and a few other
310 99-byte limits of traditional Awk.
311 Mention that if (i in a) doesn't work with traditional Awk.
313 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
315 * tests/autotest.at (BSx641-newline in command):
316 (BS-BS-newline in command, BSx640-newline in command):
317 (Newline-CODE-BS-newline in command):
318 (Single-quote-BS-newline in command):
319 (Single-quote-newline-BS-newline in command):
320 Use printf '%s\n' instead of echo, for portability to hosts
321 where echo interprets backslashes. This will break on hosts
322 that lack printf, but for now let's assume all such hosts
323 are dead (if not, we should get reports of test failures).
325 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
327 'echo' has some portability problems, when given a first argument
328 with a leading '-', or when given any argument containing '\'.
329 Avoid using 'echo' in these cases.
330 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
331 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
332 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
333 * lib/autotest/general.m4 (AT_INIT): Likewise.
334 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
335 argument might be unportable.
336 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
337 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
338 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
339 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
340 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
341 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
342 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
343 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
344 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
345 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
346 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
347 (AC_PROG_MAKE_SET): Likewise.
348 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
349 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
350 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
351 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
352 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
353 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
354 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
355 * bin/autoconf.as: Redo verbose flag implementation, as the old
356 scheme wouldn't work with AS_ECHO.
357 * lib/autotest/general.m4 (AT_INIT): Likewise.
358 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
359 Don't use ECHO_T, since ECHO_N is now reliable.
360 * lib/autotest/general.m4 (AT_INIT): Likewise.
361 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
362 rather than using a here-document to put the script into a file.
363 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
364 use AS_ECHO.
365 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
366 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
367 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
368 bug, but we might as well stop using ECHO_N and ECHO_C internally.
369 * lib/autotest/general.m4 (AT_SETUP): Likewise.
370 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
371 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
372 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
373 operand, as AS_ECHO requires. Avoid double file name expansion.
374 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
375 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
376 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
377 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
378 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
379 Double-quote strings that would otherwise contain M4 comments.
380 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
382 * configure.ac (AC_INIT): Bump to 2.61a.
383 * NEWS: Likewise.
385 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
387 Version 2.61.
389 * configure.ac (AC_INIT): Bump to 2.61.
390 * NEWS: Likewise.
392 * tests/autotest.at (Macro with backslash in a test title):
393 Comment out for now, as this tests neither fails nor passes
394 reliably. Problem reported by Ralf Wildenhues.
396 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
398 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
399 in previous change, which caused test failures.
401 2006-11-16 Stepan Kasal <kasal@ucw.cz>
403 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
404 code for --enable, --disable, --with, and --without to...
405 (_AC_INIT_PARSE_ENABLE): ... a new macro.
406 * doc/autoconf.texi (Package Options):
407 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
409 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

473 benefit of platforms like Solaris+GCC where it is common to have a
474 non-working g++ installation.

477 and Joel E. Denny <jdenny@ces.clemson.edu>
478 and Paul Eggert <eggert@cs.ucla.edu>
480 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
481 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
482 ./micro-suite.
484 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
486 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
487 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
488 Imported from a similar patch to gnulib by Bruno Haible.
490 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

509 and Stepan Kasal <kasal@ucw.cz>
511 Handle special characters in test case titles correctly.
512 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all

514 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
515 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
516 argument. Extend to check titles printed by ./micro-suite and
517 ./micro-suite -l and the title in micro-suite.log.
518 (Backquote in a test title,
519 Single-quote in a test title,
520 Double-quote in a test title): Don't expect failure anymore.
521 (Backslash in a test title): Put a non-whitespace character after the
522 backslash so that Bourne shells might actually see it as an escape
523 sequence.
524 (Brackets in a test title,
525 Pound in a test title,
526 Comma in a test title,
527 Quoted Macro in a test title,

529 Macro with single-quote in a test title): New tests.
530 (Macro with backquote in a test title,
531 Macro with double-quote in a test title,
532 Macro with backslash in a test title): New tests expected to fail.
533 * tests/torture.at (#define header templates): M4-quote this title in
534 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
535 The visible effect was a stray [] in the testsuite output.
537 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
539 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
540 `trap ... 0' inside a function, for AIX sh.
542 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
544 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
545 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
546 5363) simply issues a warning when dividing by zero at compile
547 time. Problem reported by Elias Pipping.
549 2006-10-26 Eric Blake <ebb9@byu.net>
551 * THANKS: Update.
552 * doc/autoconf.texi (Evaluation Macros): Improve the example to
553 show effect on macros that expand with commas.

578 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
580 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
581 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
582 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
583 reported by Nelson H. F. Beebe for Coreutils 6.4.
585 * tests/tools.at (autoconf --trace: user macros): Remove test
586 for tracing multiline macros, since m4 1.4.7a uses a different
587 way to number lines. Problem reported by Ralf Wildenhues.
589 2006-10-24 Stepan Kasal <kasal@ucw.cz>
591 * bin/autom4te.in (handle_m4): Do not redirect stdin to
592 /dev/null since the heuristics for interactive behaviour was
593 fixed in CVS m4.
595 * bin/autom4te.in: With --force, always refresh the output
596 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

614 * doc/autoconf.texi (Caching Results): Likewise.

617 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
618 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

649 looking for special shell characters.
650 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
651 macro defined by AS_VAR_PUSHDEF before passing it as a
652 parameter.

663 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
665 (Imported from Automake.)
666 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
667 which incorrectly sets the mode of an existing destination
668 directory. In some cases the unpatched install-sh could do the
669 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
670 system. We hope this is rare in practice, but it's clearly worth
671 fixing. Problem reported by Alex Unleashed in
672 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
673 Also, don't bother to check for -m bugs unless we're using -m;
674 suggested by Stepan Kasal.
676 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
678 Import this change from Automake:
680 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

683 Report from Bruno Haible.
685 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

694 Import this change from Gnulib:
696 2006-09-16 Karl Berry <karl@gnu.org>
697 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
698 to avoid sectioning errors.
700 Import these changes from Texinfo:
702 2006-10-04 Karl Berry <karl@gnu.org>
703 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

706 (\lquoteexpand, \quoteexpand): new defs.
707 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
708 (\code): must use new \...Char values, since now ` is active.
710 2006-08-26 Karl Berry <karl@gnu.org>
711 * build-aux/texinfo.tex (\textdegree): New command.
713 2006-08-12 Karl Berry <karl@gnu.org>

720 2006-10-13 Stepan Kasal <kasal@ucw.cz>
722 * doc/autoconf.texi (Autoheader Macros): Warn that the text
723 added to the template can get mangled.
725 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
727 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
728 include the default headers, and redefine obstack_chunk_alloc
729 and obstack_chunk_free. Fixes false failure with glibc.
731 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
733 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
734 for backward compatibility with Libtool 1.5.22. Problem reported
735 by Ralf Wildenhues.
737 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

743 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
745 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
746 the NonStop platform.
747 * doc/autoconf.texi (Posix Variants): Likewise.
748 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
750 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
751 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
752 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
753 Use a better substitute, by inspecting the output of "ls"
754 rather than just using ":".
755 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
756 rather than AS_EXECUTABLE_P, since we needn't worry about
757 non-regular files here.
759 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
760 due to configuration hassles with this. See Tonya Underwood's report
761 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
762 * doc/autoconf.texi (Special Shell Variables): Likewise.
764 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>

768 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
770 2006-10-11 Stepan Kasal <kasal@ucw.cz>
772 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
773 initialization which is not inherited through the environment
774 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
775 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
777 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
779 * doc/autoconf.texi (Limitations of Usual Tools): Describe
780 problems with mkdir -p -m.
782 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
784 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
785 comment about ac_cpp_err; it was incorrect, and anyway
786 ac_cpp_err is being removed below.
787 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
788 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
789 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
790 nobody uses it.
791 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
792 with werror_flag and conftest.err and so forth. This is more
793 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
794 and anyway the user shouldn't normally want to see this gorp logged.
795 Problem reported by Ralf Wildenhues.
796 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
797 empty, not 'no', since the rest of the code uses 'test -z'.
799 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
801 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
802 Use a single call to AC_DO_TOKENS rather than multiple, for
803 efficiency.
804 (_AC_LINK_IFELSE): Test that resulting file is executable.
805 Problem reported by mwoehlke in
806 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
808 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
809 than creating a file to use with test -x; this is much faster.
811 2006-10-02 Bruno Haible <bruno@clisp.org>
813 * lib/autom4te.in (Automake-preselections): Add
814 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
816 2006-09-27 Stepan Kasal <kasal@ucw.cz>
818 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
819 standard error, `experr' should be used, not `expout'.
821 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
823 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
824 fseeko testing program twice; just use the earlier result.
825 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
826 Set cache var to 'unknown' (not 'no') if leaving the macro unset
827 still doesn't let the program compile.
828 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
829 failed.
831 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
832 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
833 include it, without including anything else.
834 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
835 expressions.
836 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
838 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
840 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
841 `error.h', and include it, for a `error_at_line' prototype.
842 Use a nonempty format string in the link test.
843 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,

849 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
850 can apply to constants too, and that it checks for macro defns.
851 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
852 and simply cast the identifier to void. This handles structure
853 values. Problem reported by Ralf Wildenhues.
854 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
856 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

942 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
943 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
944 for the existence of the directory at configure-time. That's
945 too late, anyway. Problem reported by Stefan Seefeld.
947 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
948 7.1.4 /usr/bin/posix/sh described by Tim Rice in
949 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
951 2006-09-11 Stepan Kasal <kasal@ucw.cz>
953 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
954 works with GNU M4 1.4.3 again; make the normalized form
955 match the current m4 message; fix the description.
956 * test/tools.at (autom4te cache): Adapt to the change.
958 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
960 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
961 to catch glibc bug 2821
962 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
964 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
965 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
966 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
967 assume C89.

981 2006-09-05 Paul Eggert <eggert@cs.ucla.edu>
983 * doc/autoconf.texi (Preset Output Variables): srcdir and
984 top_srcdir are not necessarily relative. Problem reported
985 by Dries Kimpe.
987 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
989 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
990 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
991 accept files with extension `.f'. For consistency, also prefer
992 xlf over f77.
993 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
994 from last patch.
996 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>
998 * lib/autoconf/erlang.m4 (AC_ERLANG_CHECK_LIB): Added substitution
999 of ERLANG_LIB_VER_* variables.

1009 before AC_PROG_FC, due to a bug in Autoconf.
1011 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
1013 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
1014 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
1015 except the first two arguments are reversed.
1016 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1017 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
1018 caches nor outputs a diagnostic. Suggested by Bruno Haible.
1019 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
1020 equivalent to the old AC_COMPUTE_INT.
1021 (AC_COMPUTE_INT): No longer caches or reports. New signature.
1022 All uses changed to AC_CACHE_CHECK_INT.
1023 * tests/base.at (AC_CACHE_CHECK_INT): New test.
1024 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
1026 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
1028 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
1029 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
1030 programs should use their Gnulib counterparts.
1031 * doc/autoconf.texi (Particular Functions): Likewise.
1032 (Macro Names, testsuite Invocation): Replace uses of these
1033 obsolete macros with uses of non-obsolete macros.

1043 mistakenly swapped on 2006-08-15.
1045 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
1047 * NEWS: Version 2.60a.
1049 2006-08-25 Stepan Kasal <kasal@ucw.cz>
1051 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Remove the IPA/IPO
1052 file created by the PGI compiler.

1057 simplify the code.
1059 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
1061 Fix Lex library problem reported to us by Julio Garvia.
1062 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
1063 for the default, which the user can override.
1064 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1065 deal with LEXLIB.
1066 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1067 didn't work if some values were cached but not others. Test for
1068 broken lex libraries like native ia64-hp-hpux11.22; see
1069 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1070 work around the problem by preferring an empty LEXLIB to -lfl or
1071 -ll. Let the user set LEXLIB='' to indicate no library needed.
1073 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1074 * README: Likewise.
1075 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
1077 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>

1176 * doc/autoconf.texi (Particular Programs): Mention that
1177 @INSTALL@ and @MKDIR_P@ may vary for different output files.
1178 Reported by Alexandre Duret-Lutz.
1180 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
1182 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
1183 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
1184 Bill Northcott in
1185 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
1187 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>

1193 longer supported by Sun.
1195 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>

1199 -Wundef -Werror". Problem reported by David Fang in
1200 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1201 * doc/autoconf.texi (Header Templates, Default Includes):

1203 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
1204 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

1216 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1217 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1218 this.

1222 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1223 problems with arg script text that doesn't end in newline, and

1234 to last change.
1236 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1238 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1239 --help' should mention that `--version' outputs configuration
1240 settings. Report by Bruno Haible.
1242 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1244 Fix test suite failures reported by Pierre in
1245 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1246 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1247 the compiler created a file "b.out" when it didn't create anything
1248 at all.

1250 Discard stderr too, when invoking the test script.

1260 less skeptical about "volatile", after discussion with
1261 Bruno Haible on bug-gnulib.
1262 (Limitations of Usual Tools): Warn about sed stripping
1263 leading white space from text. From Bruno Haible.
1265 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1267 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1268 compiler complains about it, even if things works after the
1269 complaint. Problem reported by Peter O'Gorman.
1271 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1272 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1273 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1275 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1277 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1278 after -R regardless of host. Patrick Welche reports that this
1279 fixes things on NetBSD 3.99.
1281 * NEWS: Recommend M4 1.4.5.
1282 * README: Likewise.
1283 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
1284 * tests/tools.at (autom4te cache): Update wording of diagnostic
1285 to match M4 1.4.5.
1287 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1289 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1290 under AC_C_VOLATILE.
1291 (Volatile Objects): Be a little less skeptical about what
1292 "volatile" means. Derived from thoughts by Ben Pfaff in
1293 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1295 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1297 * doc/autoconf.texi: Fix some typos.
1299 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1301 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1302 more globally, since the 2006-06-30 patch didn't suffice. Problem
1303 reported by Keith Marshall. Also, don't bother with builddir2,
1304 since it shouldn't be needed any more.
1306 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1308 * doc/autoconf.texi (Generic compiler characteristics):
1309 Document AC_COMPUTE_INT. Fix wrong statements on Default
1310 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1312 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
1313 (_AC_COMPUTE_INT): Add obsoletion warnings.

1323 * NEWS: Document previous change.
1325 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1327 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1328 Require that long long int be at least 64 bits wide. C99 requires
1329 this and enough programs depend on it so we should check for it.
1330 Bruno Haible reports in
1331 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1332 that long long int is 32 bits wide with some nonstandard compilers.
1333 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1335 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1337 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1338 to a nonexistent file, so that we don't have to worry about
1339 a local site configuration that doesn't use /usr/local.
1340 Problem reported by Keith Marshall in
1341 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1343 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1345 * doc/autoconf.texi: Be more consistent about using @acronym with
1346 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1347 quite right (it talked about "OSF/Tru64", even though the
1348 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1349 and it even mentioned "OSF 4"!) and at this point there's little
1350 reason to talk about OSF any more, since it died in 1994.
1351 (Specific Compiler Characteristics): Simplify example of
1352 negative-size array.
1353 (File Descriptors): Reorder to make the text flow better.
1354 Remove joke about "appreciate the various levels"; I didn't get it.
1355 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1356 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1357 (File Descriptors, Limitations of Usual Tools):
1358 Tone down the advice against renaming or removing open files.
1359 (Limitations of Usual Tools): Add a new section, on 'rm'.
1361 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1363 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1364 -lXt in LIBS, idea from Karsten Hopp; this was due since
1365 this change:
1367 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1368 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1369 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc

1383 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1385 * config/texinfo.tex: Sync from upstream.
1387 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1388 quadrigraph correctly in traces.
1390 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1391 Fix typos.
1393 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1394 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1395 not defined.
1396 * doc/autoconf.texi (Changed Directory Variables): New node,
1397 to document the whole `datarootdir' business a bit better.
1398 * NEWS: Update.
1399 * tests/torture.at (datarootdir workaround): Extend test.
1400 Prompted by report by Alexandre Julliard.
1402 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1404 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1405 when using default mode of IBM C 6 for AIX. Problem and two-line
1406 fix reported by Larry Jones.
1408 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1410 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1411 about literal '${datarootdir}' if a definition is found in the
1412 output file.
1414 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1416 * NEWS: Use "M4" rather than "m4" when appropriate.
1417 Problem reported by Eric Blake.
1418 * doc/autoconf.texi: Likewise.
1419 Use @acronym around BSD, GCC, and GNU when appropriate.
1420 (Why GNU M4): Renamed from "Why GNU m4".
1421 (Redefined M4 Macros): Mention that Posix
1422 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1423 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1424 to int.
1426 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1428 * bin/autom4te.in (handle_output): Do not forbid the empty
1429 pattern.
1430 * tests/tools.at (autoconf: the empty token): New test.
1432 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1434 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1435 calls, so that we do not care whether they are LIFO or FIFO;
1436 in the m4_wrap, do not check which diversion is the topmost
1437 one, just check that the stack is balanced at the end.
1438 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1439 base diversion forever--pop the previous diversion before
1440 opening the new one; consequently, remove the m4_wrap call.
1441 * lib/autotest/general.m4 (AT_INIT): Likewise.
1442 * tests/m4sugar.at: Do not use
1443 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1445 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1446 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1448 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1449 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1450 Rework example of m4wrap token-pasting trouble so that it doesn't
1451 care whether it's LIFO or FIFO.
1452 Fix some "contrary to"s that are awkward in English.
1454 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1456 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1457 to `yes' instead of `int$1_t' if the type is found, for more
1458 consistent configure output (where $1 is the number of bits).
1459 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1460 Suggested by Bruno Haible.
1462 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1463 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1464 with system headers. Report by Bruno Haible.
1466 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1468 * config/config.guess, config/config.sub: Sync from upstream.
1470 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1471 in order to avoid picking up an older installed frozen m4sh.m4f.
1472 Besides an outdated shell startup, this could have been created
1473 by an earlier M4 version with incompatible frozen file format.
1475 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1477 * README: Recommend m4 1.4.4 instead of 1.4.3..
1478 * doc/autoconf.texi: Likewise.
1479 (Special Chars in Names): Say that $(.FOO) is portable, as
1480 suggested by Stepan Kasal.
1481 (Installation Directory Variables, Build Directories):
1482 (Automatic Remaking, Subdirectories, Fortran Compiler):
1483 (Making testsuite Scripts, Defining Directories):
1484 Quote variable usages better.
1485 (Making testsuite Scripts): Add clean-local rule to makefile
1486 snippet, by Eric Blake.
1487 (Installation Directory Variables): Fix table item font.
1488 Reword slightly to clarify. Generalize advice about
1489 not using special characters to include all file-related
1490 vars, not just VPATH.
1491 (Special Chars in Variables): Warn about special characters in
1492 $(srcdir) too.
1493 (Assignments): Clarify default-value example as suggested by
1494 Ralf Wildenhues in
1495 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1496 (Special Shell Variables): Note leading ./ or ../, as suggested
1497 by Eric Blake.
1498 (Limitations of Builtins): Under cd, warn about CDPATH.
1499 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1500 Ralf Wildenhues.
1502 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1504 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1505 `@var', for texi2html.
1506 (Systemology): Some more word wrapping, for DVI output.
1507 (autom4te Invocation): The short option for `--melt' is `-M',
1508 not `-m'.
1510 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1512 * doc/autoconf.texi: More formatting and English tweaks,
1513 many suggested by Ralf Wildenhues.
1514 Reword to avoid "@code{...}'s" and the like, since it's ugly
1515 with Emacs info mode. discontents -> woes.
1516 Put a few "will"s back. time stamp -> timestamp.
1517 side-effect -> side effect.
1519 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1521 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1522 Warn about $@ not persisting. Problem reported by Julien Danjou in
1523 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1524 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1525 Mention other special chars, too.
1527 2006-06-14 Eric Blake <ebb9@byu.net>
1529 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1531 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1533 * doc/autoconf.texi: Some systematic minor improvements, as
1534 follows. Use "makefile" when talking about makefiles
1535 generally (which might be named "makefile" or "Makefile" or even
1536 "foo.mk"), "Makefile" when talking about a specific makefile
1537 called "Makefile". This unclutters the text from weird quotes
1538 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1539 values" rather than "@var{foo}s" and similar constructs containing
1540 "}s". Use "Make rules" rather than "Makefile rules". Minor
1541 English-language improvements. Change the prefix "sub-" to "sub"
1542 and "re-" to "re".
1543 Put blank lines around examples more consistently.
1544 Avoid "rather" and "very" as intensifiers.
1545 Avoid "will" as an auxiliary.
1546 (Limitations of Make): Split this node into....
1547 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1548 (Leading _ in Macro Names, Backslash-Newline-Newline):
1549 (Backslash-Newline Comments, Long Lines in Makefiles):
1550 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1551 (obj/ and Make, make -k Status, VPATH and Make):
1552 (VPATH and Double-colon, $< in Explicit Rules):
1553 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1554 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1555 New nodes, resulting from splitup of Limitations of Make.
1556 All cross-references changed. Raise the top node from
1557 a section to a chapter, and all subnodes accordingly.
1558 Redo the introductory wording to match the new organization.
1559 (Installation Directory Variables): Use an example that is
1560 closer to what Autoconf actually does. Mention that VPATH's
1561 value should not contain metacharacters or white space.
1562 (Fortran Compiler): Fix a VPATH bug in an example.
1563 (Leading _ in Macro Names): Mention that this problem is no longer
1564 of practical concern.
1565 (VPATH and Make): Reword the advice to make it clearer
1566 that Autoconf and Automake support VPATH in non-GNU make, but
1567 many packages have bugs in this area.
1568 ($< in Explicit Rules): Refer to Build Directories rather
1569 than using a (non-VPATH-safe) example.
1570 (Automatic Rule Rewriting): Mention the sort of disaster that
1571 can ensue with Solaris-style rule rewriting with VPATH.
1573 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1575 * doc/install.texi (Compilers and Options): Weaken the
1576 suggestion to use GNU make for VPATH builds.
1578 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1579 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1581 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1582 in regular expression.
1584 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1586 * doc/autoconf.texi (Installation Directory Variables):
1587 Drop extra @samp from `@table @samp' item.
1588 (Limitations of Usual Tools): Comment fix.
1589 Do not nest @samp just to point to other table items.
1590 (Writing testsuite.at) <AT_CHECK>: The second argument to
1591 `@dvar' is already @samp'ed.
1592 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1593 do not use @var in the second argument.
1595 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1597 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1598 $as_shell.exe too. Problem reported by Andreas Buening in
1599 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1601 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1603 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1604 `unused variable' compiler warning, for `-Wall -Werror'.
1605 Reported by Jaap Haitsma in
1606 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1608 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1610 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1611 case the compiler dumps core. Problem reported for
1612 OpenServer 5.0.7 by Tim Rice in
1613 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1614 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1615 Likewise.
1617 2006-06-06 Tim Rice <tim@multitalents.net>.
1619 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1620 "ERROR" only shows up in "make check" output if there is an
1621 error.
1623 2006-06-06 Eric Blake <ebb9@byu.net>
1625 * tests/tools.at (automatically allowed tokens): Fix typo.
1627 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1629 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1631 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1632 typically overflows on x86 CPUs, even though the C standard
1633 requires otherwise.
1635 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1637 * configure.ac (AC_INIT): Bump to 2.59e.
1638 * NEWS: Update.
1640 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1642 Version 2.59d.
1644 * config/texinfo.tex: Sync from upstream.
1646 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1647 seen, invoke libtoolize with `--ltdl' argument.
1648 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1649 * NEWS: Update.
1650 Suggested by Eric Blake.
1652 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1654 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1655 reported by Ralf Wildenhues.

1666 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1668 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1669 message issued by AC_REQUIRE.

1671 * tests/base.at: Check AC_REQUIRE's error message.
1672 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1673 to...
1674 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1675 AT_CHECK_M4.
1676 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1677 `expout' as the last parameter.
1678 * tests/tools.at: Adapt to the above change.
1680 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1682 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1683 information about race-free implementations of mkdir.
1685 2006-06-04 Eric Blake <ebb9@byu.net>
1687 * bin/autoreconf.in (help): Document M4 environment variable.
1688 * bin/autoconf.as (Usage): Likewise.
1689 * bin/autom4te.in (help): Likewise.
1690 * doc/autoconf.texi (autom4te Invocation): Likewise.
1692 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1694 * NEWS: GNU make now recommended for VPATH builds.
1695 Mention that some macros are now documented to be obsolescent.
1696 * doc/autoconf.texi:
1697 Prefer "current" to "modern" to describe
1698 currently-used (albeit perhaps old-fashioned) hosts.
1699 Mention which ancient features no longer need to be worried about.
1700 setgid -> set-group-ID
1701 setuid -> set-user-ID (these are the Posix terms)
1702 Fix some misuses of "only".
1703 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1704 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1705 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1706 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1707 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1708 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1709 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1710 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1711 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1712 Mention that these macros are obsolescent.
1713 (Installation Directory Variables): shall -> should
1714 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1715 Mention that it's now safe to use 3 and 4.
1716 (Limitations of Usual Tools): cp -r is now specified by Posix.
1717 Omit longwinded and obsolescent discussion of cp -f.
1718 Modernize discussion of expr, ls.
1719 (Limitations of Make): Modernize discussion of VPATH builds.
1720 Mention $? as a workaround in some cases.
1721 * doc/install.texi (Basic Installation):
1722 Mention "./configure; make; make install" first. Be more
1723 specific about why this file is generic. Remove unnecessary
1724 parens. Remove misleading "only". Remove obsolete advice
1725 about csh. Don't say "configure" takes awhile; say it
1726 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1727 and CC=c99 rather than CC=c89, as these are blessed by current
1728 Posix. Recommend GNU make if doing a VPATH build.
1730 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1732 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1733 examples involving shell prompts.
1735 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1736 and Paul Eggert <eggert@cs.ucla.edu>
1738 * doc/autoconf.texi (Here-Documents): Add details about the
1739 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1740 use "here-documents" instead of "here documents".
1742 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1744 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1746 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1748 * doc/autoconf.texi (File System Conventions): Warn about ":"
1749 anywhere in directory names.
1751 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1753 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1754 about quoting the case statement, just in case.
1755 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1756 was fixed in ksh93g; reported by Ralf Wildenhues.
1758 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1760 * doc/autoconf.texi (System Services): Do not document
1761 overriding EXEEXT via ac_cv_exeext=ext.
1762 (Particular Programs) <AC_PROG_MKDIR_P>:
1763 Document that ${MKDIR_P} understands --.
1764 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1765 comment.
1767 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1769 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1770 argument with leading hyphen. Problem reported by Paul Eggert.
1772 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1774 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1775 about quoting ac_try: quote all of it, if any of it seems suspicious.
1776 This means we don't have to worry about ${ or sed any more.
1777 Also, double-quote the case statement, to work around misuses via
1778 underquoting as reported by Ralf Wildenhues in
1779 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1780 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1781 undocumented and dangerous macro.
1782 Problem reported by Ralf Wildenhues in
1783 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1785 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1787 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1788 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1789 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1791 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1793 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1794 since evidently some packages rely on the old, broken behavior.
1795 Problem reported by Ralf Wildenhues in
1796 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1797 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1798 pre-2006-05-26 definitions, but leave in the comments that
1799 these macros are dangerous and should not be used.
1800 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1801 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1802 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1803 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1804 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1806 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1808 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1809 the use of 'tr', since this is our only use of 'tr'.
1811 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1812 and Paul Eggert <eggert@cs.ucla.edu>
1814 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1815 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1817 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1819 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1820 the output file in the `${datarootdir}' test.
1822 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1823 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1825 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1826 mention of `datarootdir' in the input file(s), but literal
1827 `${datarootdir}' in the output file, and we haven't warned yet,
1828 then warn as well: the user may have (erroneously) used
1829 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1830 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1831 * tests/torture.at (datarootdir workaround): Extend this test.
1832 * NEWS: Update.
1834 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1835 and Paul Eggert <eggert@cs.ucla.edu>
1837 * doc/autoconf.texi (autoheader Invocation): The first argument to
1838 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1839 alternatives and clear up the language a bit.
1841 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1843 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1844 ac_config_guess, ac_config_sub, ac_configure.
1845 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1846 Fix typo that prevented an unnecessary space from being removed.
1847 Problems reported by Ralf Wildenhues in:
1848 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1850 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1852 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1853 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1854 Don't use the term "thread-safe" to talk about mkdir race
1855 conditions, since the problem is more a process than a thread
1856 issue. Problem reported by Stepan Kasal in:
1857 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1858 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1859 the test for 'install' more closely. Look at MKDIR_P first.
1860 Look in the PATH, and at /opt/sfw/bin.
1861 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1862 Don't bother to try mkdir -p, since we already check mkdir --version;
1863 just look at the version number. (There's no easy way to check
1864 for race-free implementations.)
1865 * tests/tools.at (autoconf: subdirectories): Adjust to above
1866 changes, since MKDIR_P now might end in "/mkdir -p".
1868 * doc/autoconf.texi (autoheader Invocation): Mention that the
1869 first arg of AC_DEFINE_UNQUOTED must be a literal.
1870 Problem reported by Ben Pfaff in
1871 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1873 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1874 * doc/autoconf.texi (Special Chars in Variables): New section.
1875 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1876 (Installation Directory Variables): Quote $(datadir) better.
1877 (Limitations of Builtins): Describe some of eval's trickiness.
1879 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1880 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1881 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1882 in front of every arg, not just trailing args. Quote apostrophes.
1883 (_AC_EVAL_ECHO): New macro.
1884 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1885 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1886 removed.
1887 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1888 exposed by quoting of eval argument. Put the command on line line
1889 so it logs better.
1890 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1891 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1892 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1893 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1894 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1895 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1896 Use eval more safely.
1897 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1898 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1899 to be replaced.
1900 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1901 lines, exposed by quoting of eval argument.
1903 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1904 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1906 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1907 initialization of `ac_cv_exeext', do not override it if it was
1908 already set, unless it was set to `no', for compatibility with
1909 Autoconf-2.13, and comment this.
1910 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1911 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1912 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1913 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1914 Document that this test may be overridden by setting
1915 `ac_cv_exeext'.
1917 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1919 Revert these two patches:
1921 2006-04-06 Eric Blake <ebb9@byu.net>
1922 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1923 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1924 2006-04-01.
1926 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1927 Clean up _AC_COMPILER_EXEEXT* macros.
1928 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1929 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1930 ac_file to the name of the default output file and call
1931 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1932 initial `rm' of the candidate files...
1933 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1934 the same list in subsequent `rm' calls, and for the temporary
1935 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1936 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1937 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1938 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1939 no longer needed) by libtool. Make it a cache check.
1940 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1941 copied here by mistake.
1942 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1943 _AC_COMPILER_EXEEXT.
1944 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1945 _AC_COMPILER_OBJEXT directly.
1946 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1948 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1950 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1951 Fix description of how the buggy `sed' works.
1953 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1955 Sync from Automake:
1957 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1958 ENOLCK. Only mention `make -j' when applicable. Only raise
1959 fatal errors when `make -j' is involved. Improve error message.
1961 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1963 * doc/autoconf.texi (Here-Documents): We now know more about
1964 the variable expansion in here documents bug.
1965 Thanks to Tim Rice and Stepan Kasal.
1967 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1968 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1970 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1972 * tests/autotest.at (Multiline command from M4 expansion):
1973 No failure to be expected if the shell quotes newlines in
1974 commands in the `set -x' output. Report by Tim Rice.
1975 * THANKS: Update.
1977 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1979 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1980 expansion in the here-documents used by config.status, as that
1981 runs afoul of the Korn shell version M-12/28/93d bug described in
1982 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1983 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1984 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1986 2006-05-23 Jim Meyering <jim@meyering.net>
1988 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1989 Fix typo introduced with 2006-04-02 change. It reversed the sense
1990 of the test.
1992 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1994 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1995 ac_dB slightly, to save bytes in the script.
1996 Max out at 50 lines, rather than 96; this is more likely
1997 (though not guaranteed) to avoid obscure 'sed' failures.
1999 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2001 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2002 `tr -d -' as bad option argument. Work around this by deleting
2003 an unrelated character.
2004 Report by Tim Rice <tim@multitalents.net>.
2006 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2007 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2008 Stepan Kasal <kasal@ucw.cz>
2010 * doc/autoconf.texi (Particular Programs): Do not promise that
2011 we always prefer the GNU version of the program, and that we
2012 search according to PATH; both rules can have exceptions.
2013 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2014 AC_PROG_SED. Move descriptions of limitations
2015 to the Limitations of Usual Tools section.
2016 (Limitations of Usual Tools) <sed>: Mention script length
2017 limitations with Solaris /usr/ucb/sed.
2018 <grep>: Fix wording for empty alternative. Mention that -c and
2019 -l should not be combined, and that -E and -F should not be
2020 combined.
2022 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2023 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2025 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2026 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2028 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2030 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2031 AC_DEFINE is now passed to m4_pattern_allow.
2032 * NEWS: Mention that; likewise for AC_SUBST.
2033 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2034 the parameter to m4_pattern_allow.
2035 * tests/tools.at: Add a check for that.
2037 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2039 * lib/autoconf/status.m4: Fix typos.
2041 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2043 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2044 only the files that this macro generates.
2046 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2048 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2049 the HP-UX sed limitation of 99 commands, labels do not count.
2050 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2051 in the comment.
2052 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2054 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2056 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2057 Import the following fix from coreutils:
2059 2006-01-13 Jim Meyering <jim@meyering.net>
2061 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2062 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2063 not double-quote uses of that variable, to accommodate the rare
2064 case in which getmntent is available in none of the libraries
2065 checked. This happens at least on FreeBSD 5.0.
2067 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2069 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2070 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2071 some other programs unwisely rely on these undocumented vars.
2072 But put in warning comments about them.
2073 Problem reported by Ralf Wildenhues in
2074 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2075 * NEWS: Document that these variables are intended to go away.
2077 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2079 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2080 and set the language to C++ (analogous to the equivalent Fortran
2081 tests).
2083 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2084 * doc/autoconf.texi (C++ Compiler): Document it.
2085 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2086 * NEWS: Update.
2088 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2090 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2091 that caused config.status to generate 100-command sed scripts; the
2092 portable limit is 99.
2094 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2096 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2097 variable `ac_d' instead of `d' to avoid infringing namespace.
2098 Report by Ralf Menzel.
2100 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2102 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2103 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2104 * tests/tools.at (autoconf: subdirectories): New test, taken from
2105 the corresponding problem report by Ralf Wildenhues in:
2106 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2108 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2109 Quote some uses of shell variables if they might suffer unexpected
2110 globbing. This doesn't fix all instances of quoting problems that
2111 I found, just the easy ones that look safe.
2112 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2113 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2114 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2115 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2116 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2117 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2118 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2119 Likewise.
2120 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2121 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2123 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2125 * bin/autoreconf.in ($help): Reword according to the manual.
2126 Suggested by Olly Betts.
2128 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2129 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2131 * bin/autoreconf.in: Pass the directory argument to
2132 `require_configure_ac'. Fix comment.
2133 * tests/torture.at (Configuring subdirectories): Expose this.
2134 Reported by Olly Betts.
2136 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2138 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2139 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2140 Automake as follows:
2142 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2143 `$configure_in' instead of `configure.in', to preserve
2144 directory component.
2146 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2148 * config/config.guess, config/config.sub, config/texinfo.tex,
2149 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2151 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2153 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2154 test for C99 conformance; (bool) 0.5 is an integer constant
2155 expression, but (bool) -0.5 is not. Problem reported by Fedor
2156 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2158 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2160 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2161 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2162 Warn about obsolete install-sh files. Remove stray sentence
2163 fragment and fix cross reference.
2164 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2165 install -d; this undoes the 2006-05-10 change.
2166 (MKDIR_P): Mark with AN_MAKEVAR.
2167 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2168 that we don't require $INSTALL to be thread-safe. Move comments
2169 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2170 of AC_PROG_INSTALL. Output a message saying that we're checking
2171 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2172 MKDIR_P instead of AC_SUBST.
2173 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2174 Special magic for MKDIR_P, too.
2175 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2176 a dnl.
2177 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2179 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2181 Sync from Automake, as follows:
2183 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2184 * config/install-sh: Initialize IFS, so field splitting isn't
2185 turned off later.
2186 * config/mkinstalldirs: Likewise.
2187 * config/missing: Remove superfluous quotes. Replace all uses of
2188 `[' by `test', for consistency, and for..
2189 * config/missing (sed_minuso, sed_output): New variables.
2190 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2191 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2192 Fixes `missing' to detect `--output' for help2man. Fixes
2193 PR automake/483. Report by Dennis J. Linse.
2194 (autom4te): Document in `missing --help'.
2196 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2198 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2199 * config/install-sh: Don't use 'path' to talk about file names,
2200 as per GNU coding standards. Close a race condition reported by Ralf
2201 Wildenhues and Stepan Kasal. There is still a race condition
2202 on hosts that predate Posix 1003.1-1992, but we can't help this.
2203 Don't mishandle weird characters like space on pre-Posix hosts.
2204 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2205 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2206 AC_PROG_MKDIR_P from AS_MKDIR_P.
2207 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2208 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2209 earlier editions are not (including Automake 1.8.3).
2210 Do not suggest mkinstalldirs for thread-safety.
2211 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2212 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2213 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2214 presence of special characters and race conditions.
2215 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2216 in Autoconf's name space.
2218 2006-05-10 Bruno Haible <bruno@clisp.org>
2219 and Paul Eggert <eggert@cs.ucla.edu>
2221 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2222 from Automake with minor changes.
2223 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2225 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2227 * config/install-sh: Update to Automake CVS version, as follows:
2228 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2229 * lib/install-sh: Simplify the expr implementation of dirname.
2230 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2231 * lib/install-sh: Handle --, and diagnose unknown options.
2233 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2235 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2236 `./autom4te' to create `./testsuite', since the `all' target
2237 will ensure its presence, but `installcheck' should not create
2238 the uninstalled wrappers.
2240 * tests/torture.at (Unusual Automake input files): Skip if we
2241 detect automake < 1.8.
2243 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2245 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2246 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2247 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2248 * NEWS: Update.
2250 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2252 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2253 munge (multiple) white space and other oddities.
2254 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2255 single quotes in variable assignment.
2256 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2257 and similar failures by adding multiple spaces, tabs, and other
2258 special characters.
2259 Report and different test suggested by Francesco Romani
2260 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2262 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2263 single quotes, we only need to search for single quotes; this
2264 both simplifies the search pattern, and makes us less
2265 susceptible to `echo' variations for arguments not containing
2266 single quotes.
2267 (_AC_ARG_VAR_VALIDATE): Likewise.
2269 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2271 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2272 `$*' and IFS concatenation issue with traditional shells and

2284 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2285 and Bruno Haible <bruno@clisp.org>
2287 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2288 about 'od'.
2289 (Integer Overflow): Mention the special case of integer division
2290 overflow.
2292 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2294 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2295 traditional shells like the Solaris one that do not use the
2296 first IFS character for assembling `$*'.
2297 Prompted by a related report from autoconf_bug@nro.ca.
2299 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2300 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2302 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2303 Mention more problems with the -e option.

2317 continuous text.
2318 (Runtime): Fix macro argument names to match description:
2319 `action-if-found' -> `action-if-true' and similarly.
2320 (Obsolete Macros): Likewise.
2321 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2322 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2323 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2325 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2327 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2329 * ChangeLog: Typo.

2346 with status 1, not merely nonzero. Clarify exit declaration.
2347 (Run Time): Move C exit status stuff to new Exiting Portably section.
2348 (Systemology): Mention Posix and levenez. Update v7 reference.
2349 (Portable Shell): Mention the Posix shell.
2351 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2353 * bin/autoconf.as (me): Replace by as_me.
2355 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2357 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2358 since as_me isn't set yet.
2360 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2362 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2363 a few minor bugs in this area.
2365 * doc/autoconf.texi (Programming in M4sh): Comment out the
2366 documentation of AS_BASENAME, for now.
2367 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2368 (Limitations of Builtins) <basename>: Do not refer to
2369 AS_BASENAME.
2370 * bin/autoconf.as (me): Don't use AS_BASENAME.
2371 (dir): Remove the unused variable.
2372 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2373 AS_DETECT_REQUIRED. All uses changed.

2375 All uses changed.
2376 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

2378 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2379 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2380 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2381 (_AS_DIRNAME_PREPARE): Likewise.

2386 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2388 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses

2391 * lib/autoconf/functions.m4: Likewise.
2392 * lib/autoconf/general.m4: Likewise.
2393 * lib/autoconf/headers.m4: Likewise.
2395 * doc/autoconf.texi (Run Time): Document the exit status situation
2396 with more accuracy and detail.
2398 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2400 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2401 Archive is not officially `GNU' any more. Update URL.
2402 (Defining Directories): Likewise
2403 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2405 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2407 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2408 newline from the `trap' code to finish `config.log'; the NetBSD
2409 /bin/sh resets the exit status after an empty command, as
2410 documented in doc/autoconf.texi.
2411 Reported by Dalibor Topic <robilad@kaffe.org>.
2413 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2415 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2416 Suggested by Bruno Haible.
2418 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2420 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2421 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2422 Instead, just list the shells that we know work.
2423 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2424 changed. Be more cautious about the _cv_ variable.
2425 * tests/tools.at (Syntax of the shell scripts): Check the
2426 _cv_ variable once, at first, to avoid an internal autoconf error
2427 when sh -n does not work.
2429 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2431 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2433 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2435 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2436 use ">&-" since we're only 99.999% sure that this is portable,
2437 and since the MinGW bug is fixed in a different way.
2438 * lib/autotest/general.m4 (AT_INIT): Likewise.
2440 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2442 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2443 before opening config.log, to avoid hitting a bug on MinGW.
2445 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2447 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2448 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2449 This works around a MinGW bug reported by Eric Paire.
2450 Make sure that all writes to the log file append to it,
2451 rather than possibly losing data.
2452 * lib/autotest/general.m4 (AT_INIT): Likewise.
2454 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2456 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2457 description.
2459 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2461 * NEWS: Update.
2463 * configure.ac (AC_INIT): Bump to 2.59d.
2465 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2467 Version 2.59c.
2469 * Makefile.maint (news-date-check): Do not require a leading `*'
2470 before the release date in NEWS.
2472 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2473 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2475 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2476 the instantiated file do not contain the string 'datarootdir'
2477 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2478 @mandir@, replace the reference '${datarootdir}' by the value.
2479 * tests/torture.at (datarootdir workaround): New test.
2480 * NEWS: Advertise this temporary fixup.
2481 Based on a patch by Bruno Haible, reported and analyzed by
2482 Paul Eggert and Noah Misch.
2484 2006-04-12 Eric Blake <ebb9@byu.net>
2486 * tests/autotest.at (Debugging a failed test): Fix comment.
2488 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2490 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2491 all the changes since 2006-04-07.
2493 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2495 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2496 succeeded, but `ln -s file dir' failed, take care to remove the
2497 leftover target before the next test, to prevent its spurious
2498 failure; also make sure `ln file dir' works before selecting it.
2499 Thanks to Keith Marshall for pointing this out.
2500 * THANKS: Update.
2502 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2503 assignments in `at_debug_args', so that we put them correctly
2504 in the `run' script.
2505 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2506 Reported by Eric Blake.
2508 2006-04-11 Eric Blake <ebb9@byu.net>
2510 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2511 top-level tests after micro-suite has been run. Used in...
2512 (Debugging a successful test, Debugging script and environment),
2513 (Debugging a failed test): ...these new tests. The first of these
2514 is fixed by...
2515 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2516 macro, split out from...
2517 (AT_INIT): ...here, so that using -d also generates a run script.
2518 Document that -d inhibits top-level logging.
2519 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2520 inhibits top-level logging; debug scripts are created.
2522 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2523 check.
2524 * tests/autotest.at (Empty test, Empty check): New test to check it.
2526 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2527 from gcc.
2529 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2531 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2532 the files if a problem appears. Make the empty *.at files
2533 read-only, too. Proposed by Ralf Wildenhues.
2535 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2537 * config/Makefile.am: Add comment to force updated Makefile.in.
2539 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2540 space only patch to this file, this patch causes the Makefile.in
2541 files that include freeze.mk to be updated, and thus have a
2542 newer time stamp again, which in turn makes a pristine CVS
2543 checkout have correct time stamps.
2545 * Makefile.maint (cvs-sv): New macro, to be used..
2546 (config.guess-url_prefix, config.sub-url_prefix)
2547 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2548 point to CVS text checkout of Gnulib files.
2549 (copyright-check): Bump current year.
2550 (announcement): Do not hard-wire `./announce-gen'.
2551 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2552 correctly.
2553 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2554 `chmod +x'.
2555 (wget_files): Update config.guess, config.sub, texinfo.tex by
2556 `wget-update', now that their URLs work again.
2558 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2560 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2561 Problem noted by Paul D. Smith.
2563 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2565 * doc/autoconf.texi: Remove unused words from word list.
2566 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2567 .x-sc_trailing_space: New files.
2569 * doc/standards.texi: Sync from gnulib.
2571 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2572 `LIBOBJDIR' as experimental.
2574 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2575 with a target directory; it's internally implemented as `cp'
2576 anyway, but since Autoconf advertises the possibility to use
2577 a target directory when LN_S is `ln -s', we need to find out.
2578 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2579 analyzed by Keith Marshall <keith.marshall@total.com>.
2581 * THANKS: Update.
2583 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2585 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2586 confdefs.h as-is. In general, if it has backslash-newline or the
2587 like, then it doesn't work either to sort or to remove empty
2588 lines.
2590 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2592 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2594 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2596 * lib/autom4te.in (Automake-preselections): Preselect
2597 _AM_SUBST_NOTMAKE.
2599 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2601 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2602 apostrophe within a single-quoted string, as this is the usual
2603 tradition and is easier to read than '"'"'. Don't rely on the
2604 shell treating "$/" like '$/'. Use a more-consistent indenting
2605 style for the trap.
2607 2006-04-09 Eric Blake <ebb9@byu.net>
2609 * tests/autotest.at (Backquote command substitution),
2610 (Multiline backquote command substitution): Remove mistaken
2611 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2612 applied...
2613 (Parenthetical command substitution, Multiline parenthetical
2614 command substitution): here.
2616 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2618 Import macros from gnulib (often changing their name).
2620 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
2621 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
2622 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

2632 (Pointers): Add Gnulib URL.
2633 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2634 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2635 Gnulib section.
2636 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
2637 suggest a #define rather than a typedef for _Bool, and mention
2638 Gnulib rather than trying to substitute stdbool code.
2639 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
2640 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2641 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
2642 AC_STRUCT_DIRENT_D_TYPE.

2644 headers too.
2645 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2646 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2647 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2648 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2649 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2650 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2651 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2652 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2653 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2654 (Coding Style). Don't mention m4_expand_once.
2655 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

2662 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
2663 (AC_HEADER_ASSERT): New macro.
2664 (AC_HEADER_STDBOOL): Don't assume "#error" works.
2665 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2666 Catch a bug in an HP-UX C compiler.
2667 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2668 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
2669 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

2671 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
2672 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2673 New macros.
2675 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2676 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2678 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2680 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2681 of the warning introduced by the 2001-08-28 change.
2683 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
2684 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2686 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2687 variables shall be overriden by the cache.
2688 * tests/torture.at (AC_ARG_VAR): Test also with a first value
2689 that contains braces.
2691 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2693 Revert the patch from 2006-04-01 and only improve
2694 _AS_DETECT_BETTER_SHELL:
2696 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2697 skip nonexistent directories.
2698 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2699 only shell candidates which exist.
2700 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2701 * lib/autotest/general.m4 (AT_INIT): No need to give three
2702 parameters to _AS_PATH_WALK.
2704 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2705 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2707 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2708 distinguish m4sugar macros.
2709 * tests/tools.at (autoupdating with aclocal and m4_include):
2710 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2711 test case by Noah Misch <noah@cs.caltech.edu>.
2713 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2715 Revert my change from 2006-03-17, in other words:
2716 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2717 and DUALCASE=1.
2718 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2719 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2720 it is set.
2722 2006-04-07 Eric Blake <ebb9@byu.net>
2724 * doc/autoconf.texi (Programming in M4sh): Document that
2725 AS_MKDIR_P exits the script on failure.
2726 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2728 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2730 * config/elisp-comp, config/install-sh, config/mdate-sh,
2731 config/missing, config/mkinstalldirs: Sync from Automake.
2733 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2734 from Automake.
2736 * doc/make-stds.texi: Sync from gnulib.
2738 2006-04-06 Eric Blake <ebb9@byu.net>
2740 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2741 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2742 2006-04-01.
2744 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2745 Eric Blake <ebb9@byu.net>,
2746 Paul Eggert <eggert@cs.ucla.edu>,
2747 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2749 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2750 whether `set' quotes correctly: redirect stderr of the tested
2751 `set', and use a subshell, for Ultrix; use `sed' instead of
2752 `grep' for zsh `set' which may write binary output; match only
2753 at the beginning of a line, to avoid false positives.
2754 In order to avoid false positives by unrelated variables with
2755 multiline content, put the dump algorithm in a subshell and
2756 unset all variables containing newlines (except some which are
2757 special to the shell). Warn about cache variables that are
2758 unset.
2760 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2762 * config/config.guess, config/config.sub, config/texinfo.tex:
2763 Sync from upstream.
2765 * tests/mktests.sh: Reword comments.
2767 * tests/mktests.sh: Only skip internal macros starting with
2768 `_AC_' or `__AC_'. Noted by Stepan Kasal.
2769 Update exclusion lists for the test suite to this end:
2770 (AC_ARG_VAR): Do test this now.
2771 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2772 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2773 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2774 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2776 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2777 shell issue with double-quoted command substitutions of native
2778 commands.
2779 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2780 Marshall.
2782 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
2783 no file matches the glob, discard the warning, set `nullglob'.
2784 (syntax-check): Likewise.
2785 (sc_cast_of_x_alloc_return_value): Likewise.
2786 (sc_cast_of_alloca_return_value, sc_error_exit_success)

2790 (sc_tight_scope): Do not fail for non-existing `src' directory.
2791 (sc_changelog): Skip the Copyright footer.
2792 * lib/autoconf/lang.m4: Remove trailing space.
2794 * lib/autoconf/status.m4: More replacements to
2795 <tab><space> where this makes sense.
2797 2006-04-06 Stepan Kasal <kasal@ucw.cz>
2799 * tests/Makefile.am (maintainer-check-posix):
2800 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2802 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2803 ac_config_<foo>s again, sometimes normalized, sometimes not.
2804 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2805 (AC_CONFIG_COMMANDS): Do not do so here.
2806 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2807 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2808 2005-07-25 rewrite. Noticed by Noah Misch.
2810 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2811 _AC_PRESERVE_HELP_ORDER, ...
2812 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2814 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2815 inside m4_expand_once; it is redundant.
2817 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
2818 for --help from Cygnus `configure.'
2820 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
2822 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
2823 on a patch proposed by Ralf Wildenhues.
2825 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2827 * lib/autoconf/status.m4: Replace <space>''<tab> with
2828 <tab><space> where this makes sense.
2830 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
2831 Noah Misch <noah@cs.caltech.edu>
2833 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
2834 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
2835 * doc/autoconf.texi (Help Formatting): New node.
2836 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
2838 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2840 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
2841 lib/autoconf/specific.m4, lib/autoconf/status.m4,
2842 lib/autoconf/types.m4, lib/autotest/general.m4,
2843 tests/mktests.sh, tests/torture.at: White space cleanup:
2844 remove some SPACE before TAB, or add quoting ('' or @&t@).
2846 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
2848 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
2850 2006-04-05 Eric Blake <ebb9@byu.net>
2852 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
2853 empty test suite works.
2854 * tests/autotest.at (Empty test suite): Remove xfail.
2856 2006-04-05 Noah Misch <noah@cs.caltech.edu>
2858 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
2859 TAGS to ac_config_<foo>s.
2860 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
2861 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
2862 normalizing it, consistent it with previous releases.
2863 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
2865 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2867 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
2868 Use simplified args that Eric Blake originally suggested.
2870 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
2872 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
2873 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
2874 Use 'comm' rather than N instances of grep; this also fixes a bug
2875 whereby substrings were incorrectly matched, causing us to not
2876 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2877 (exclude_list): Exclude empty macros.
2878 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
2880 Use awk rather than grep -E or egrep, to avoid
2881 portability problems with regular expressions containing newlines.

2883 Switch from grep to awk syntax.
2884 (ac_exclude_script): Renamed from ac_exclude_egrep.
2885 (au_exclude_script): Renamed from au_exclude_egrep.
2887 2006-04-04 Noah Misch <noah@cs.caltech.edu>
2889 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
2890 a subdirectory subject to Cygnus `configure'.
2891 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
2893 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
2894 report request when we have no AC_PACKAGE_BUGREPORT.
2896 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2898 * THANKS: Update.

2901 generated files.
2903 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
2904 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
2905 typedef'ed restricted pointer, to catch a compiler bug on
2906 HP-UX 11.x, and fix warnings so it passes with -Werror.
2907 (_AC_PROG_CC_C99): Likewise.
2908 Reported by Albert Chin <china@thewrittenword.com>.
2909 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

2924 * THANKS: Add myself.
2926 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2928 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
2929 to log, point to testsuite output tree.
2931 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
2933 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
2934 * doc/autoconf.texi (Function Portability): Mention that C++
2935 has trouble with 'exit'.
2936 (Guidelines): Test programs shouldn't use 'exit'.
2937 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
2938 Remove; all uses removed.
2939 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

2959 Clean up _AC_COMPILER_EXEEXT* macros.
2961 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2962 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2963 ac_file to the name of the default output file and call
2964 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2965 initial `rm' of the candidate files...
2966 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2967 the same list in subsequent `rm' calls, and for the temporary
2968 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2969 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2970 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2971 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2972 no longer needed) by libtool. Make it a cache check.
2973 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2974 copied here by mistake.
2975 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2976 _AC_COMPILER_EXEEXT.
2977 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2978 _AC_COMPILER_OBJEXT directly.

3004 * lib/m4sugar/m4sh.m4: Sort sections as implied by the comments,
3005 and fix some typos.
3007 2006-04-01 Noah Misch <noah@cs.caltech.edu>
3009 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
3010 Autoconf version number despite a zero- or one-argument AC_INIT.
3012 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
3013 subordinate tools.
3014 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
3015 * doc/autoconf.texi (autoreconf Invocation): Document it.
3017 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
3018 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

3024 rm failed to remove it.
3026 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3028 * bin/autoupdate.in: Redefine m4_location so that warnings print
3029 the correct lines of the input file by subtracting..
3030 (_au__first_line): ..this new definition.
3032 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
3033 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
3034 Remove stray newline in output.
3035 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
3036 AC_DEFUN this for autoconf, including the obsoletion diagnose.
3037 Fixes autoupdating of code where the replacement output contains
3038 m4sugar macros.
3039 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
3040 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

3042 * tests/tools.at: Several new tests for all of this.
3043 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
3044 hairy details.
3045 The AC_LANG_SAVE issue was reported against Libtool by
3046 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
3047 Kristian Kvilekval <kris@cs.ucsb.edu>.
3049 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3051 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3052 switch all of them on and of when necessary. Fixes the bug when
3053 m4sugar macros (e.g., m4_define) were expanded after the first
3054 automatic update (e.g., after AC_PREREQ or AC_INIT).
3056 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

3081 aclocal cannot be given on the command line.
3083 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
3085 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
3086 Give an example for AS_DIRNAME instead of referring to Posix..
3087 (File System Conventions): Put discussion of // versus / here, and
3088 modernize it a bit.
3089 (Limitations of Usual Tools): Add basename. Remove verbiage
3090 after dirname, since it got moved to the above sections.
3091 All this was inspired by a patch proposed earlier by Eric Blake.
3093 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3095 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Quote

3099 `$0', $as_me.
3101 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3103 * bin/autoscan.in: The value of find_configure_ac should be
3104 checked for existence, so we don't barf over a nonexisting
3105 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
3107 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3109 * bin/autoupdate.in: Fix some typos.
3111 2006-03-21 Stepan Kasal <kasal@ucw.cz>
3113 * doc/autoconf.texi (Installation Directory Variables): Fix typo.
3115 * lib/autoscan/autoscan.list: Refreshed.
3117 2006-03-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3605 that Posix has about { }. Use better quoting.
3606 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_HEADER):
3607 Rewrite to conform to Posix rules about { } in sed scripts.
3608 * lib/m4sugar/m4sh.m4 (AS_DIRNAME_SED, AS_BASENAME_SED): Likewise.
3609 * tests/foreign.at (Libtool): Likewise.
3610 * tests/semantics.at (AC_CHECK_PROG & AC_CHECK_PROGS):

3626 shell from zsh to bash.
3628 2005-12-31 Stepan Kasal <kasal@ucw.cz>
3630 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
3631 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
3633 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
3635 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced
3636 parentheses in $(...). Problem reported by Eric Blake.

3664 (Limitations of Builtins): Likewise.
3666 2005-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3668 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Pass
3669 CONFIG_SHELL in the environment of the configure rerun.
3670 * doc/autoconf.texi (Here-Documents, config.status Invocation):
3671 Suggest passing CONFIG_SHELL absolute, and in the environment
3672 rather than as option.
3674 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3676 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

3688 ac_clean_files and LIBOBJS.
3690 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3692 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
3693 Factor functionality to..
3694 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
3695 `AC_SUBST($1)' in the public version.
3696 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
3697 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
3698 ac_pt_* variables.
3700 2005-11-01 Stepan Kasal <kasal@ucw.cz>
3702 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
3703 filesystems.

3709 2005-10-27 Stepan Kasal <kasal@ucw.cz>
3711 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
3712 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3714 2005-10-25 Stepan Kasal <kasal@ucw.cz>
3716 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
3717 conftst2.$ac_objext.
3718 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3720 2005-10-24 Stepan Kasal <kasal@ucw.cz>
3722 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
3723 conftest.o, to see whether the compiler really obeys; rm the object
3724 file before and after the test and register it with ac_clean_files.
3725 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3727 2005-10-21 Stepan Kasal <kasal@ucw.cz>
3729 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
3730 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
3731 code so that the most common case requires less forks.
3733 2005-10-20 Stepan Kasal <kasal@ucw.cz>
3735 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
3736 not portable; thanks to Paul Eggert and Alexandre.
3738 * NEWS: Fix an old typo.
3740 2005-10-20 Jim Meyering <jim@meyering.net>

3743 the latter'', in two places.
3745 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
3747 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
3748 AC_LANG_PROGRAM, fixing a typo. Don't give details about
3749 the inner workings of AC_LANG_FUNC_LINK_TRY.
3750 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3751 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3752 by the function rather than ignoring it.
3753 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3754 comparing its address. Intel's interprocedural optimization was
3755 outsmarting the old heuristic. Problem reported by
3756 Mikulas Patocka.
3758 2005-10-19 Stepan Kasal <kasal@ucw.cz>
3760 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
3762 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
3764 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

3767 2005-10-04 Stepan Kasal <kasal@ucw.cz>
3769 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
3770 before removing it (chmod -R u+rwx); there are three instances of this.
3772 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3773 Stepan Kasal <kasal@ucw.cz>
3775 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3776 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3777 make its content writable before removing it. Remove an errorneous
3778 comment from the end, where the logs of the failed tests are copied
3779 to the main log file.
3781 2005-09-27 Stepan Kasal <kasal@ucw.cz>
3783 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
3784 in case the computer is too quick. Double quote the configure.ac
3785 snippets.
3787 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
3788 problems if the testsuite were running too fast.
3790 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3792 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3793 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3794 (which belong to Xt, not X itself). See Debian bug 327655.
3795 * NEWS: Mention this.
3797 2005-09-07 Stepan Kasal <kasal@ucw.cz>
3799 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
3801 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
3803 * config/move-if-change: Don't output "$2 is unchanged";
3804 suggested by Ben Elliston. Handle weird characters correctly.
3806 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3808 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3809 calls, so that the final expansion of this macro is shorter.
3810 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3811 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3812 the cleanup there. Use AS_VAR_* macros, to be more general.
3813 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3815 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3817 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3819 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3821 * doc/autoconf.texi (Configuration Headers): Add an index entry
3822 for AH_HEADER.
3824 2005-08-26 Pavel Roskin <proski@gnu.org>
3826 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
3827 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
3828 running xmkmf.
3830 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3832 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3833 The previous patch didn't work, so try a better one.
3835 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3837 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3838 in the example. Reported by Bruno Haible.
3839 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3840 "if $undefined_var;" succeeds with my shell.
3842 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3843 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3844 but change the m4_divert_text to m4_divert_once.
3846 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3848 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3849 Work around bug in Solaris /usr/xpg4/bin/awk.
3850 The bug is present in at least Solaris 8 through 10.
3852 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3854 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3855 some evil values and relying on the fact that $* concatenates the
3856 parameters by the first character from IFS.
3858 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3859 Stepan Kasal <kasal@ucw.cz>
3861 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3862 first header appears, define AH_HEADER.
3863 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3864 Update limitations about when to call AC_CONFIG_HEADERS.
3865 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3866 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3867 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3868 ``Configuration Actions''; fix their index entries.
3870 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3871 options correctly. Process N-M as M-N if M is smaller than N.
3872 Process ranges correctly so that N-N will run only N.
3873 Sort and uniquify the tests that will be run. If there is more
3874 than one test, reinsert the banners for the tests.
3875 * tests/autotest.at (Keywords): Unmark XFAIL.
3877 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3879 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3880 before passing the macro name to AH_TEMPLATE.
3882 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3883 now opens log after option processing; in particular, --version
3884 and --help do not touch config.log.
3886 * Makefile.maint: Revert the change from 2005-08-12.
3888 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3890 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3891 common code to...
3892 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
3894 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3896 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3897 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3898 Language cleanup.
3900 * doc/autoconf.texi (Defining Symbols, Changed Results):
3901 Prepend to LIBS, not append, in examples.
3903 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3905 When building in place, set srcdir="."; suggested by Tim Van Holder.
3907 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3908 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3909 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3910 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3911 does not mean "no --srcdir option".
3913 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3915 * tests/autoscan.at (autoscan): New file.
3916 * tests/suite.at: Use it.
3917 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3918 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3920 * tests/autotest.at (Keywords): Test keywords combinations.
3922 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3924 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3925 add "2>&1"; gzip 1.2.4 prints help on stderr.
3927 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3929 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3930 was pushdef'ed twice while popped only once. Push it only once.
3931 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3933 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3935 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
3936 prefixed by mere "===", not "configure: === ".
3938 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
3940 * Makefile.maint: Update from Bison.
3942 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3943 "<tab>" in comment, so that the point is understandable.
3945 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3947 Rewrite substantial part of lib/autoconf/status.m4.
3948 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3949 and CONFIG_COMMANDS are not processed in four separate loops.
3950 Instead, there is one main loop. This alows that the common code
3951 is expanded only once, thus config.status (and configure) is smaller.
3953 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3954 the AC_LIST_FILES and cousins macros are no longer used.
3956 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3957 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3958 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3959 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3960 contain the initialization, nor the for loop, nor the associated
3961 commands; all these go to ...
3962 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3963 _AC_OUTPUT_CONFIG_STATUS.
3964 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3965 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3966 (_AC_OUTPUT_FILE): The creation of the sed script ...
3967 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3968 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3969 _AC_OUTPUT_MAIN_LOOP.
3970 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3971 _AC_CONFIG_COMMANDS): Use ...
3972 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3973 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3974 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3975 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3976 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3977 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3978 ... new macros.
3979 (_AC_CONFIG_UNIQUE): Update.
3980 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3981 Replaced by this ...
3982 (_AC_LIST_TAGS): ... new common macro.
3983 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3984 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3985 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3986 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3987 this didn't belong to the `config commands' section.
3988 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3989 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3990 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3991 to the `config commands' section either.
3992 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3993 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3995 ... and many changes to the comments nearby.
3997 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3998 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3999 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4000 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4001 (#define header templates): The comment at the top of the generated
4002 header now includes the name(s) of the source file(s).
4004 Several unrelated small changes:
4006 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4007 parameter to AC_DIAGNOSE.
4008 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4009 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4010 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4011 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4012 with AU::AC_OUTPUT.
4013 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4014 in AC_OUTPUT doesn't double-quote it either.
4015 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4016 parameters.
4018 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4020 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4021 versions of Portland Group compiler produce single- and double-quoted
4022 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4023 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4025 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4027 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4028 This is a corrected version of yesterday's patch.
4030 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4032 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4033 path, too; insert a "===" to emphasize the line.
4035 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4036 ac_cv_build_alias to ac_build_alias.
4037 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4039 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4040 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4041 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4042 (AC_ARG_VAR): ... here.
4043 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4044 target_alias.
4046 Keep a list of all precious variables and process them with one simple
4047 for loop, instead of expanding all commands, or, OTOH, complicated
4048 processing of output of "set".
4049 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4050 variable names in new macro...
4051 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4052 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4053 a loop to assign all ac_env_* and ac_cv_env_* variables.
4054 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4055 to INIT_PREPARE.
4056 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4057 its value to shell variable ac_precious_vars and call
4058 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4059 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4060 _AC_ARG_VAR_VALIDATE.

4083 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4085 Fix my changes from 2005-07-01; reported by Noah Misch.
4086 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4087 description, the macro now accepts only a single tag.

4096 versions of autoconf.
4098 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4100 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

4103 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4105 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4106 sed substitution command, so that we allow | in program prefixes

4110 configure_input, top_builddir, srcdir, etc.
4111 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4112 PATH_SEPARATOR in AUTOTEST_PATH.
4114 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

4122 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

4147 Likewise for --header; moreover, recognize --he and --h as shortcuts
4148 for --help in that case.
4150 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4151 matches the order of execution. No code changed.

4173 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4174 (AC_SUBST): Call it.
4175 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4176 the directory specific variables; but don't call it for configure_input.
4178 2005-06-28 Derek Price <derek@ximbiot.com>
4180 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4181 addition.
4183 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4185 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4186 directory have inherent problems with special characters like spaces,
4187 due to limitations in Make syntax. Problem reported by Alexandre
4188 Duret-Lutz.
4189 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4204 variable into diagnostic. Make the diagnostic an error, not a warning,
4205 because we really don't support spaces and suchlike in dir names.
4206 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4207 Don't worry about backslashes in srcdir; it can't happen now.

4232 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4234 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4235 b, t, r, w commands require single space, while : cannot have any.
4236 (Special Shell Variables): Fix sed code this in the example.
4237 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4238 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4240 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4241 expand to the empty list. Don't use two pairs of m4_changequote,
4242 it's not necessary.
4244 2005-06-20 Derek Price <derek@ximbiot.com>
4246 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4248 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4250 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4251 * doc/autoconf.texi:
4252 Don't mention Solaris versions so much, if a
4253 problem is common to all extant versions of Solaris. Say "SunOS
4254 4" instead of "SunOS" for SunOS 4.
4255 (awk): Mention more of the limitations of traditional Awk.
4256 (cat): Don't talk about cat -v.
4258 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

4263 to be compatible with glibc strverscmp.
4264 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4266 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4267 on Mac OS X 10.4 reported by Peter O'Gorman in:

4269 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4270 Use shell builtins rather than 'expr', to work around expr bug.
4272 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4274 * doc/autoconf.texi: "filesystem" -> "file system".
4275 "behaviour" -> "behavior".

4278 as per POSIX.
4279 * lib/m4sugar/m4sh.m4: Likewise.
4280 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem

4283 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4284 (.x.1): Ignore the time stamp in the .TH line when deciding whether

4289 quotes and backslashes. Patch from Derek Price.

4294 AS_TR_SH.
4296 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4298 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4299 -u, since it outputs chatter if the input files are the same.
4300 Problem reported by Ralf Menzel.
4302 2005-06-08 Derek Price <derek@ximbiot.com>
4304 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4305 renaming them since they are about to be redefined anyhow.
4307 2005-06-08 Derek Price <derek@ximbiot.com>
4309 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4310 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4311 Move m4_undefine to alphabetical order.
4313 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4315 * README: Recommend GNU M4 1.4.3 or later.
4316 * doc/autoconf.texi (Introduction): Likewise.
4317 Reword to avoid some formatting glitches.
4318 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4319 Clarify explanation of HP compiler bug.
4320 Redo example output tp match current CVS snapshot.
4321 Use @example.org in email addresses when the examples
4322 might get inadvertently cut-and-pasted into user code.
4323 Remove example of autom4te usage that doesn't seem to work now.
4324 Use modern AC_INIT (except when the example is meant to be
4325 shown with Autoconf 2.13).
4326 Update ksh info for Solaris 9 and later.
4327 KB -> kB.
4328 Modernize description of Automake versions a bit.
4329 Don't claim a future version of Autoconf is near.
4330 * doc/install.texi: Reword to avoid some formatting glitches.
4332 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4335 follows its own advice about quoting better.
4336 Reword to avoid some formatting glitches.
4337 * doc/installt.exi: Reword to avoid some formatting glitches.
4339 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4340 Tru64 ksh pattern matching bug. Reported against Libtool by
4341 Albert Chin <libtool@mlists.thewrittenword.com> and
4342 Nicolas Joly <njoly@pasteur.fr>.
4344 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4346 m4_cdr of one-member list was [[]] (one-member list containing an
4347 empty string) instead of [] (an empty list. Callers were skewed to
4348 match this misbehaviour. As a consequence of this:
4349 - m4_foreach([x], [], [foo]) expanded to `foo', while
4350 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4351 This bug has been fixed:
4353 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4354 expand to an empty string; print error msg if called without
4355 an argument list.
4356 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4357 misbehaviour; handle [] and [[]] correctly.

4365 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4367 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4368 swallow records with more than 99 fields.
4369 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4370 parse the long line.
4372 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4374 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4375 swallow literals longer than 399. Reported by Ralf Wildenhues.
4376 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

4381 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4382 to gfortran, and make these the first two compiler names
4383 checked (following the general autoconf preference for gcc).
4385 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4387 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4388 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4389 (testsuite): Make sure autotest.m4f is up-to-date before using it.

4393 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4394 expression of unbounded size when processing the --list
4395 option. This runs afoul of a limit of 399 bytes per regular
4396 expression on AIX. Problem reported by Ralf Wildenhues.
4398 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

4405 Reword description of line replacement.
4407 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4409 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4410 now contain newlines, and substituted files must be referenced on
4411 a line alone; the sed scripts to substitute them are now very
4412 different.
4413 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4414 commands can be put in a sed script portably.
4415 * doc/autoconf.texi (Setting Output Variables): Document above
4416 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

4427 * tests/local.at: Don't attempt to check for negated character
4428 classes in shell scripts. The test was too brittle.
4430 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4432 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4433 * doc/autoconf.texi (Limitations of Builtins): Document this
4434 limitation.
4436 2005-05-24 Stepan Kasal <kasal@ucw.cz>

4446 messages when ac_unique_file is not found.
4447 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4448 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4449 commands, for consistency with AC_MSG_ERROR and such.

4463 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4464 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4465 (ac_top_builddir): ... this ...
4466 (ac_top_build_prefix): ... to this; the old name is also kept, for
4467 backward compatibility.
4468 (ac_top_builddir_sub): New variable, without the trailing slash,
4469 always nonempty.
4470 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

4484 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4485 argument to m4_foreach. I guess it was necessary in the past,
4486 but I think it's a no-op now.
4488 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4490 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4491 ``cat <<_ACEOF'' commands to one.
4492 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4493 * lib/autoconf/status.m4: On various places, use expr instead of
4494 ``echo|sed.''
4495 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4496 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

4498 a range.
4499 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

4550 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
4551 check.
4552 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
4553 enough arguments, similarly as in m4_bpatsubsts.
4555 2005-05-12 Stepan Kasal <kasal@ucw.cz>
4557 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

4560 2005-05-11 Stepan Kasal <kasal@ucw.cz>
4562 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4563 for absolute directory names in one loop.
4564 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
4565 abbreviations of --version and --debug.
4567 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4569 * doc/autoconf.texi (Autoconf Language): Be more precise about
4570 quoting rules. Problems noted by Stepan Kasal.
4571 Also, throughout this document, be more careful about white space.
4572 "blank", "white space", and "space" all have different meanings
4573 and we should be careful to say what we mean.
4575 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4577 Fix C++ related problems reported by Werner Lemberg.
4578 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
4579 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
4580 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4581 avoid problems with C++ and throw.
4582 * tests/compile.at: .cpp, not .cc.
4584 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
4586 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4588 * doc/autoconf.texi (Generic Functions): Typos.
4590 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4592 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4593 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4594 set by latest automake.
4596 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4598 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4599 outputs 0 on GNU/Linux these days.
4601 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4603 * doc/autoconf.texi (Autoconf Language): Add more description
4604 about quoting heuristics.
4605 (Limitations of Builtins): Describe "set -" problems.
4607 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4609 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4610 not newline.
4612 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4613 by AC_DEFINE; it was a mistake.
4614 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4616 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4618 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4620 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4622 * doc/autoconf.texi (External Software): Quadrigraphs are not
4623 processed correctly in AS_HELP_STRING; avoid this in the examples.
4624 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4625 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4626 comment and reduce m4_default([foo], []) to [foo].
4627 (m4_strip): Update the explanation.
4629 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4631 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4632 Remove core.conftest.* too; it's generated by Tru64 5.1.
4633 Problem reported by Jennis Pruett.
4634 * lib/autoconf/functions.m4
4635 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4636 Don't bother to remove core files; AC_RUN_IFELSE should do that
4637 for you.
4639 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4641 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
4643 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
4645 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
4646 Report from Horst Wente.
4648 2005-04-15 Stepan Kasal <kasal@ucw.cz>

4651 the comment.
4653 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
4655 * doc/autoconf.texi (External Software, Package Options): Add
4656 examples showing how to implement --with-* and --enable-* options.
4658 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4660 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4661 as well as configure.in. Problem reported by Gregorio Guidi.
4663 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4665 * doc/autoconf.texi (Particular Functions): Use gnulib's current
4666 pattern for alloca snippet.
4668 2005-04-04 Stepan Kasal <kasal@ucw.cz>
4670 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

4674 * doc/autoconf.texi (Generic Programs): Fix a typo.
4676 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
4678 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
4679 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4681 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4683 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4684 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4685 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4686 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4687 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4689 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4691 * NEWS: The configure command now warns you if you attempt to use
4692 a directory whose name contains a special character like space,
4693 newline, or "\".
4694 * doc/autoconf.texi (Installation Directory Variables): Allow
4695 "," in file names. Do not use \@; it's not a portable regexp.
4696 * bin/Makefile.am (edit): Likewise.
4697 * lib/Makefile.am (edit): Likewise.
4698 * tests/Makefile.am (edit): Likewise.
4699 * tests/semantics.at: Likewise.
4700 * tests/torture.at: Likewise.
4701 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4702 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4703 * doc/autoconf.texi (File System Conventions): Warn about
4704 unportable file names.
4705 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4706 (AC_INIT): Use it.
4707 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4708 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4709 ac_pwd, and quote srcdir.
4710 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4712 * doc/autoconf.texi: Fix some systematic formatting problems.
4713 ".)" needs a following @: if not at the end of a sentence, and
4714 similarly for "!)". "etc." should be preceded by a comma.
4715 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4717 2005-03-22 Bruno Haible <bruno@clisp.org>
4719 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4720 argument is often called 'build-aux'.
4722 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4724 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4725 macro AC_TRY_LINK is obsolete.
4726 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4727 `AC_CONFIG_FILES'.
4729 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4731 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4732 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4733 from a Common Lisp's `cl'.
4734 (AC_PROG_CXX): Behave according to the documentation: don't
4735 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4736 make the variable CCC precious; use `cl.exe', not `cl'.
4738 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4739 Alexandre Duret-Lutz <adl@gnu.org>
4741 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4742 /dev/null, as "configure" shouldn't read stdin, and this insulates
4743 us from problems (e.g., when testing for "cl"). Also, do this
4744 redirection before invoking "hostname" or "uname", and keep the
4745 original input stream available via...
4746 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4747 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4748 bother with "</dev/null" since it's now done at the top of
4749 'configure'.
4750 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4751 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4752 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4753 * doc/autoconf.texi (File Descriptor Macros): New section.
4754 (Printing Messages): Mention it.
4755 * tests/base.at (Input/Output): New test.
4757 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4759 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4760 newline if neither \c nor -n work, as that would output two
4761 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4763 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4765 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4766 This causes that any required macros inside will get before the if.
4767 * doc/autoconf.texi (autom4te.cache): A typo.
4769 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4771 Undo previous change, except keep the change to
4772 lib/autoconf/programs.m4 that replaced grep with shell
4773 pattern-matching. This is because net-snmp configure reads stdin.
4774 Reported by Noah Misch.
4776 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4778 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4779 from /dev/null, as "configure" shouldn't read stdin, and this
4780 insulates us from problems (e.g., when testing for "cl").
4781 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4782 before invoking "hostname" or "uname".
4783 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4784 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4785 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4786 "</dev/null" since it's now done at the top of 'configure'.
4787 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4788 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4789 Also, replace grep with shell pattern-matching, to save a process.
4791 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4793 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4794 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4795 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4796 compiler.
4798 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4800 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4801 grep -q isn't portable. Improve grep -s explanation.
4802 Problem reported by Dan Manthey.
4804 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4806 * doc/autoconf.texi (Special Shell Variables): Clarify
4807 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4809 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4811 * doc/autoconf.texi: Use @acronym for DJGPP.
4812 Fix some @code's that should have been @env's, and vice versa.
4813 Sort environment variable names.
4814 Mention that shells no longer inherit IFS.
4815 Don't recommend PATH_SEPARATOR=';' so strongly.
4816 Mention that $RANDOM might expand to the empty string.
4817 "symlink" and "soft link" -> "symbolic link".
4818 Improve mktemp description (reported by Bruno Haible).
4820 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4822 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4823 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4824 Likewise.
4825 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
4826 Likewise.
4828 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
4830 * NEWS: Mention AT_COPYRIGHT.
4832 * tests/local.at (AT_CMP): Use diff directly on input files rather
4833 than copying them.
4835 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4836 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
4838 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4839 and Paul Eggert <eggert@cs.ucla.edu>
4841 * tests/autotest.at (Empty test suite): New test.
4842 * tests/torture.at (Substitute and define special characters)
4843 (Substitute a 2000-byte string, Define to a 2000-byte string)
4844 (Substitute a newline, Define a newline): New tests.
4846 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4848 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
4849 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4850 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
4851 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
4852 (Standard regular expressions): New test.
4853 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4854 excess test name quoting.
4855 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4856 CPPFLAGS to `configure' instead of setting it in `configure'.
4858 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4859 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4860 on some platforms.
4862 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4863 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
4865 * tests/local.at (AT_CMP): New macro.
4866 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
4867 (AC_SAVE_STATE): Move environment grep...
4868 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
4869 (AT_CONFIG_CMP): New macro.
4870 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
4871 * tests/c.at (Extensions): Do not exit early.
4872 * tests/atlocal.in: Inherit $GREP.
4874 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
4875 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
4877 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
4878 (AC_COPYRIGHT): Factor header comment portion out and move into...
4879 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
4880 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
4881 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
4882 --version output.
4883 * tests/local.at: Add Autoconf test suite copyright notice.
4884 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
4886 2005-02-04 Bruno Haible <bruno@clisp.org>
4887 and Paul Eggert <eggert@cs.ucla.edu>
4889 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
4891 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4893 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4894 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4896 Try not to generated lines of unlimited length, as POSIX places a
4897 2047-byte limit on line length of portable text files.
4898 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4899 Use newline as a separator, not space.
4900 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4901 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4902 space.
4904 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4906 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4907 as_func_*. Add test to check whether positional parameters
4908 are restored after function return.
4910 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4912 * doc/autoconf.texi (Special Shell Variables): Mention _,
4913 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4914 if they contain a lower-case letter. The DUALCASE problem was
4915 reported by Ralf Wildenhues.
4917 * bin/autoconf.as: Don't exit with status 0 after write failure
4918 with --help or --version.
4919 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
4920 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
4922 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4924 * doc/autoconf.texi (Limitations of Usual Tools):
4925 Unicos 9 sed limitations.
4926 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
4927 to get the option-enhanced interface on older Crays. Try ftn for
4928 Fortran 95 (newer Crays).
4930 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4932 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4933 care to echo the commands, so the user knows what's going on.
4934 Modified from a suggestion by Stepan Kasal.
4936 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
4937 with a cross reference. Derived from a suggestion by Bruce Korb.
4939 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
4941 * doc/autoconf.texi (config.status Invocation): Warn about
4942 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
4943 * doc/install.texi (Defining Variables): Likewise.
4944 Based on a proposed patch by Ralf Wildenhues.
4946 * man/Makefile.am (.x.1): Make sure the required generated files
4947 are up to date. Problem and original solution proposed by Stepan Kasal.
4948 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
4949 implicit-man-prerequisites): New rules, used by the above.
4951 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.

4957 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4958 Update the long comment explaining it.
4960 m4_require no longer writes an ``is required by'' line to the
4961 execution stack. It contains only one bit of non-redundant
4962 information: that the macro was required, not called. And even
4963 this bit is useless in most situations: have you ever met a macro
4964 which both calls and requires the same macro?
4966 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4967 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4968 macro.
4969 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4970 (m4_expansion_stack_pop): Remove the misplaced comment.
4971 (m4_require): Don't put the ``is required by'' line to the
4972 execution stack; slightly improve the out-of-a-defun error message.
4973 (_m4_divert_grow): New macro, counter for the temporary diversions.
4974 (_m4_require_call): Use it.
4975 * tests/m4sugar.at (m4_require): Expect output without the
4976 ``is required by'' messages.
4978 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4980 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4981 rather than x for expr.
4983 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4984 this is safe.
4985 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4986 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

4999 support.
5000 * bin/autoheader.in: Pass $force to update_file so that
5001 config.h.in is always recreated when --force.

5012 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5014 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5015 Warn about newline stripping in `` and $(). Update Solaris
5016 version to 9.

5020 stripping.
5022 2005-01-19 Stepan Kasal <kasal@ucw.cz>

5042 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
5044 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5046 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
5047 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
5048 datadir, infodir, and mandir. Adjust argument parsing code.

5070 otherwise.
5071 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5072 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5073 stored in _m4_divert_diversion or _m4_divert_dump.
5074 (m4_divert_pop): When the parameter is given, compare the symbolic
5075 name with the last diversion pushed on the stack. Previously, the
5076 current diversion was compared with the numeric value of the
5077 diversion given as the parameter.
5078 (m4_require): If the macro hasn't been expanded yet, call ...
5079 (_m4_require_call): this new macro.

5112 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

5114 not essential. Reported by Magnus Therning.
5115 * tests/torture.at (autoreconf.): New banner.
5116 (autoreconf and non-AC configure): Rename to `Non-Autoconf

5165 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
5166 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

5293 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

5358 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>

5361 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5362 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
5363 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

5367 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

5378 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
5379 out the common code to ...
5380 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
5381 value of the #define--default to 1, iff the macro was called
5382 with exactly one parameter.
5384 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5386 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5387 "char c = '\200';" rather than "char c = 0x80;" as the
5388 latter doesn't conform to the strict C standard due to
5389 overflow on signed char hosts.
5391 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5392 to -qlanglvl=ansi. We don't want to disable extensions.
5394 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
5396 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

5411 * doc/autoconf.texi (Libtool): Libtool can be used without
5412 Automake (not without Autoconf).
5413 (Introduction): Mention lists.gnu.org.
5414 * BUGS: Don't mention bugs.gnu.org.
5415 Remove mention of ancient libtool compatibility problem.
5416 * NEWS: Mention that bugs.gnu.org is kaput.
5417 * README: Likewise. Mention where mailing list archives can be found.
5419 2004-11-28 Stepan Kasal <kasal@ucw.cz>

5425 * doc/autoconf.texi (Pretty Help Strings): Go back to
5426 single-quoting assignments to cache variables.
5428 2004-11-23 Stepan Kasal <kasal@ucw.cz>
5430 * doc/autoconf.texi (Pretty Help Strings): Fix quoting issues
5431 with the examples; fix the bug in MY_ARG_WITH example reported
5432 by Alexandre Duret-Lutz.

5446 (Quotation Rule Of Thumb): Likewise.
5447 (Pretty Help Strings): Likewise; remove the wrong comment;
5448 simplify the examples and improve their quoting.
5450 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5452 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5453 the $1_found variable, don't test whether the file is executable;
5454 Both things are checked ...
5455 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
5456 the former ``test -f''.
5457 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
5459 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
5461 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
5462 use cp -R instead.
5464 2004-11-10 Derek R. Price <derek@ximbiot.com>
5466 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
5467 limitations. Reorder paragraphs for clarity.
5469 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
5471 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
5472 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
5473 variants", "Unix", and some related minor wording fixups.
5475 (Shellology, Special Shell Variables): Document that the Zsh
5476 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

5488 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
5490 * doc/autoconf.texi (auindex): New macro.
5491 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
5492 Problem reported by Stepan Kasal.
5494 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5496 Fix problems reported by Andreas Buening in:
5497 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
5498 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5499 in test makefile.
5500 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
5501 readable; it's not true in OS/2-emx.
5503 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5505 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5506 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5507 (trivial change). Problem and patch reported by Andrew Church in:
5508 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5510 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5512 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
5513 three args in examples. Problem reported by Frederik Fouvry in:
5514 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
5515 Also, fix some minor spacing and punctuation bugs.
5517 2004-09-02 Akim Demaille <akim@epita.fr>
5519 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
5520 "case" to restore ordering.
5521 Reported by Stepan Kasal.
5523 2004-08-26 Akim Demaille <akim@epita.fr>
5525 * doc/autoconf.texi: Minor typos and stylos.
5527 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>

5531 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
5533 Version 2.59b.
5535 * README: Add advice about m4 1.4.2.
5537 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5538 texinfo.tex for now (done by hand now).
5539 * Makefile.maint (wget_files, cvs_files):
5540 Remove ansi2knr.c; nobody uses it.
5541 (ansi2knr.c-url_prefix): Remove.
5542 (cvs-update): Fix test for failure. I don't know why it ever
5543 worked...
5545 * doc/autoconf.texi: Update URLs, some of which went stale.
5546 Use @uref rather than @href.
5548 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5549 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5551 * config/config.guess, config/config.sub, config/elisp-comp,
5552 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5553 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5555 * NEWS, TODO, configure.ac, bin/autoscan.in,
5556 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5557 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5561 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5562 tests/tools.at, tests/torture.at:
5563 Use "file name" rather than "filename" or "path",
5564 to be consistent with the terminology of the GNU coding standards.
5566 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5568 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5569 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5570 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5571 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5573 More fixes to support spaces in the name of the build directory.
5574 This isn't a complete fix but it's an improvement.
5576 * bin/autoconf.as (autom4te_options): New var.
5577 Use it instead of appending to AUTOM4TE, so that we can allow
5578 spaces in the build directory's absolute name.
5579 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5580 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5581 AT_CHECK_NOESCAPE): Likewise.
5582 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5583 main program): Likewise.
5585 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5587 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

5591 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5593 * doc/autoconf.texi (Function Portability): Document isinf and
5594 and isnan. From a suggestion by Kevin Ryde.
5596 * lib/Autom4te/General.pm (END): Return correct exit status even
5597 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5599 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5601 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5602 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5603 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5605 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5607 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5608 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5609 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5610 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5611 * lib/autom4te.in (Automake-preselections): Preselect
5612 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5614 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5616 * lib/autom4te.in (Automake-preselections): Preselect
5617 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5618 trace them.
5620 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5622 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5623 Tru64.
5624 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5625 Document problem with "`""`" in pdksh POSIX mode.
5627 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5629 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5630 with pdksh, too. Problem reported by Patrick Welche via
5631 Gary V. Vaughan.
5632 * doc/autoconf.texi (Shellology): Note that set -o posix is
5633 useful for pkdsh, too.
5635 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5637 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5638 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5639 Don't fail if ENV or BASH_ENV is readonly.
5640 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5641 etc. are read only. Problem reported by Ludovic Courtes.
5643 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5645 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5646 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5647 (trivial change)
5649 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5651 * doc/autoconf.texi (File System Conventions): Warn about
5652 names like "aux". Problem reported by Eric Blake.
5654 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5655 by zero instead of array size, so that we can use any arithmetic
5656 constant expression (instead of requiring an integer constant
5657 expression). This allows us to test expressions like DBL_MAX <
5658 LDBL_MAX, which didn't conform to the C standard using the old
5659 method.
5660 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5661 now that we can do floating-point tests at compile time.
5663 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5665 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5666 and LDBL_EPSILON, as the resulting expression isn't an
5667 integer constant expression and violates the C standard.
5668 Problem reported by Nelson H. F. Beebe. Also, check
5669 for "L" suffix, and check that long double doesn't have
5670 worse range or precision than double, that mixed-mode
5671 arithmetic doesn't generate a diagnostic, that double
5672 constants fit in long double.
5674 2004-06-03 Kevin Ryde <user42@zip.com.au>
5676 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5677 malloc(0) and realloc(NULL,size).
5679 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5680 Bob Proulx.
5682 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5684 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5685 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5686 by Jim Meyering.
5688 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5690 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5691 can be rewritten using if-then-else. Suggested by Bruno Haible.
5693 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5695 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5696 Problem reported by Stepan Kasal.
5698 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5700 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5701 change). Patch reported by Ralf Wildenhues in
5702 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5704 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5705 function F exists if the compiler and linker let you compile an
5706 expression like (F != 0). Recent versions of GCC optimize away
5707 the reference to F in that case, since every function address must
5708 be nonzero, so the link succeeds even if F does not exist.
5709 Problem reported by Manu in
5710 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5712 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5713 "Unix". Many uses changed.
5714 (Limitations of Builtins): Explain better why the ! command isn't
5715 portable.
5717 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5719 * lib/autom4te.in (Automake-preselections): Preselect
5720 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5722 2004-05-19 Kevin Ryde <user42@zip.com.au>
5724 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5725 referencing AC_FUNC_STRERROR_R.
5727 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5728 note pessimistic assumption when cross compiling.
5730 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5732 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5733 (until 2004) invoked subcommands with sh -e, contra POSIX.
5734 Reported by Kevin Ryde.
5736 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5738 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5739 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5740 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5741 `test -f " /usr/bin/grep"', which _always_ failed.
5742 (AC_PROG_SED): Ditto bogus PATH fix.
5743 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5744 requires that grep correctly supports _multiple_ `-e' options, rather
5745 than stating only that grep should accept `-e'.
5747 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5749 Port to C99, which requires that 'exit' be declared.
5751 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5752 to ensure that stdlib.h is included.
5753 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5754 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5755 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5756 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5757 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5758 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5759 when using 'exit' in a test; C99 requires that 'exit' be declared.
5761 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5763 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5764 now prefers 'grep' implementations that accept -e.
5765 (Limitations of Usual Tools): Describe problems of traditional
5766 egrep and fgrep with long input lines, and of traditional grep
5767 with -e.
5768 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5769 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5770 All callers changed. Append /usr/xpg4/bin to the PATH, for
5771 Solaris.
5772 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5773 the user with complaints about multiple -e options.
5774 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5775 Define it with AC_PROG_GREP.
5776 * configure.ac (AC_PROG_GREP): Add.
5777 * lib/freeze.mk (GREP): New macro.
5779 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5781 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5782 a possible candidate only after all others fail, rather than
5783 consulting it first. This improves backward compatibility by
5784 better reflecting the way shell selection occurred in previous
5785 versions of Autoconf, and should help to avoid triggering latent
5786 problems in other packages, such as the one in Automake where zsh
5787 is not handled robustly:
5788 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5789 Although it is not Autoconf's responsibility to work around
5790 problems in Automake, it nevertheless makes sense to avoid
5791 introducing unnecessary incompatibilites.
5793 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5794 Gary V. Vaughan <gary@gnu.org>
5796 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5797 how deeply nested we are when a suitable tool is found, set the
5798 ac_path_TOOL_found flag.
5799 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5800 nested we are in this macro. Break out of all 3 nested loops if
5801 ac_path_TOOL_found is set.
5803 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5805 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5806 of the _AS_PATH_WALK loop too if GNU flavor is found.
5808 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5810 * doc/autoconf.texi (Limitations of Make): Update documentation
5811 for `$<'. New entry `Long lines', based on a report from Simon
5812 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5813 paragraph about DJGPP, based on a mail from Richard Dawe.
5815 2004-04-20 Paul Eggert <eggert@twinsun.com>
5817 * tests/c.at (C keywords): Don't assume that GCC supports
5818 "restrict" and "inline", as sufficiently-old GCC versions do not
5819 (also, GCC configured to be in pedantic C89 mode does not).
5820 Problem reported by Sumit Pandya in:
5821 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5823 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5824 consider -g to work if it generates warnings when plain compiles
5825 don't. Problem reported by Braden McDaniel in:
5826 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5828 * doc/autoconf.texi (Slashes): New section, to document a problem
5829 reported by Jim Meyering in:
5830 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5832 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5833 linker output files before linking, to work around IRIX 6 linker bug.
5834 Problem reported by Rainer Orth in:
5835 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5837 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5839 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5840 best tool so far counter rely on the tool path variable name to
5841 avoid checks for one tool being affected by the results of running
5842 the length check on a previous tool.
5844 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5845 match expression argument, as different greps have different
5846 regular expression flavours.
5847 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5848 literals.
5849 (AC_PROG_EGREP): Pass 'EGREP$'.
5850 (AC_PROG_GREP): Pass 'GREP$'.
5852 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5854 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5855 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5857 2004-03-29 Paul Eggert <eggert@twinsun.com>
5859 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5860 Types, Specific Compiler Characteristics, System Services,
5861 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5862 etc. consistently instead of 'long', 'short', 'unsigned' etc.

5879 HAVE_STRUCT_TM_TM_ZONE is not defined.
5880 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5881 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

5939 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5940 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than

5967 2004-02-18 Paul Eggert <eggert@twinsun.com>
5969 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5970 problem on QNX reported by Stephen Rasku in
5971 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5973 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

5982 AC_SUBST provides no portable way to escape literal newlines.
5984 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5985 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5986 Darwin uses -lcrt2.o and there's little point to cataloging all
5987 the system variants. Partial fix reported by Andreas Waechter in:
5988 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

6012 Eric Sunshine <sunshine@sunshineco.com>
6013 Paul Eggert <eggert@twinsun.com>

6019 (_AS_SHELL_FN_SPY): New macro.
6020 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

6031 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
6032 use AS_INIT_WITH_SHELL_FN.
6033 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6035 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

6063 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

6065 the 2003-05-22 change, which removed the older years from the list.
6066 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6068 2004-01-27 Gary V. Vaughan <gary@gnu.org>

6108 sources.
6110 2004-01-26 Paul Eggert <eggert@twinsun.com>
6112 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6113 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6114 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6115 not <inttypes.h>. Problem reported by Tim Mooney in
6116 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6117 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6118 Likewise.
6120 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6121 otherwise "make check" fails because it forbids cmp (I guess
6122 because cmp treats files as binary on DOS-like systems).
6124 * tests/mktests.sh: Update copyright date to 2004, since some tests
6125 have changed in 2004.
6127 2004-01-23 Gary V. Vaughan <gary@gnu.org>

6130 non-truncating sed or gsed program in PATH.

6133 * NEWS: Updated.
6135 2004-01-15 Paul Eggert <eggert@twinsun.com>
6137 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6138 -std1 disables some useful extensions on Tru64. Problem reported
6139 by N. Lichtmaier in
6140 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6142 2004-01-14 Paul Eggert <eggert@twinsun.com>
6144 * doc/autoconf.texi (Programming in M4sh): Document that
6145 AS_MKDIR_P succeeds if the destination is a symbolic link
6146 to an existing directory.
6147 (Limitations of Usual Tools): Note that mkdir -p might not
6148 succeed on symlinks to directories.
6150 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6152 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6153 * bin/autoheader.in: Grammar fix in message.
6154 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6155 Test for dir before calling mkdir -p. (trivial changes)

6159 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6160 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6162 2004-01-10 Jim Meyering <jim@meyering.net>
6164 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6166 2004-01-09 Paul Eggert <eggert@twinsun.com>
6168 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6169 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6170 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6171 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6172 AC_COMPILE_IFELSE, since we now assume our caller invokes
6173 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6174 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6175 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6176 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6178 2004-01-07 Paul Eggert <eggert@twinsun.com>
6180 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6181 `"'...'"`, as it's confusing (and I suspect it may not work on
6182 some platforms). The code was incorrect anyway, as it assumed
6183 that \$ evaluated to itself in that context. Reported by
6184 Alexandre Duret-Lutz.
6186 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6188 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

6193 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6194 example, and add more examples. Reported by Eric Sunshine.
6196 2004-01-05 Paul Eggert <eggert@twinsun.com>
6198 * doc/autoconf.texi (Limitations of Usual Tools):
6199 Remove warning against "rm -fr" introduced yesterday; it
6200 was a false alarm.
6202 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6203 autoscan, autoupdate, ifnames): Don't use chmod -w.
6204 * lib/Makefile.am (autom4te.cfg): Likewise.
6205 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6206 "chmod -w".

6211 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts

6216 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6217 Use "rm -f" to remove conftest.sed, not plain "rm".
6218 Bug reported by David Relson in
6219 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6221 * Makefile.am (autom4te-update):
6222 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6223 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6224 * doc/autoconf.texi (Guidelines): Likewise.

6232 srcdir): Likewise.
6233 * doc/autoconf.texi (Limitations of Usual Tools):
6234 Warn against "rm -fr".
6236 2004-01-03 Paul Eggert <eggert@twinsun.com>
6238 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6239 -c -o might not work. From a suggestion by Kevin Ryde.
6240 (C Compiler, Generating Sources, Limitations
6241 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6242 Don't put '-o' after non-options, as POSIX doesn't allow this.
6243 Mention that cc's name might be gcc or c89 or whatever.
6245 2004-01-04 Kevin Ryde <user42@zip.com.au>
6247 * doc/autoconf.texi: Add various further index entries.
6249 2003-12-29 Paul Eggert <eggert@twinsun.com>
6251 * bin/autoreconf.in (autoreconf_current_directory):
6252 Fix typo: mkdir without umask arg.
6254 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6256 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6257 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6258 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6259 explanation clearer.
6261 2003-12-24 Andreas Schwab <schwab@suse.de>
6263 * doc/autoconf.texi (Default Includes): Fix misspelling of
6264 AC_INCLUDES_DEFAULT.

6268 * configure.ac: Test if sh -n works.
6269 * configure: Regenerate.
6270 * tests/atlocal.in: Store the result here.
6271 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6272 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6273 of explicitly testing.
6274 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6275 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6276 * tests/tools.at (Syntax of the shell scripts): Simplify
6277 using AT_CHECK_SHELL_SYNTAX.
6278 (Syntax of the Perl scripts): Remove definition of
6279 AT_CHECK_PERL_SYNTAX.
6281 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6283 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
6284 stderr to /dev/null.

6291 Extracted from AS_SHELL_SANITIZE.
6292 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6293 macros.
6294 (AS_SHELL_SANITIZE): Move reinvocation code from
6295 _AS_LINENO_WORKS, use it to find out if shell
6296 functions work.
6297 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6298 does not work.
6299 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

6310 * config/announce-gen (&print_locations, &print_signatures)
6311 (&sizes): New.
6312 Use them.
6313 No longer rely on Gnus to inline the list of signatures: compute
6314 them on the fly.
6316 2003-11-24 Akim Demaille <akim@epita.fr>
6318 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
6319 override some files.
6320 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
6321 From Debian Autoconf 2.58.
6323 2003-11-24 Akim Demaille <akim@epita.fr>

6361 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6362 than $target since the latter is not usual, add guidelines on when to

6367 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

6387 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

6522 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
6523 cross test.
6525 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
6527 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
6528 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

6540 Problems reported by Eric Sunshine.
6542 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6544 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6545 -mGLOB_options_string stuff for Intel ifc, which can cause
6546 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

6569 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6570 cache variable instead of $G77 to decide whether to include -O2,
6571 since $G77 is specific to Fortran 77.

6575 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

6580 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6581 arguments so that it can be used with syntax identical to
6582 AC_PROG_F77, and so that we can more easily decide to
6583 remove/deprecate the DIALECT optional argument in the future if it
6584 proves troublesome.
6585 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6586 non-freeform-supporting compilers. Document freeform flags.
6588 2003-10-03 Akim Demaille <akim@epita.fr>
6590 * configure.ac: Look for emacs, not macs.

6593 2003-10-03 Akim Demaille <akim@epita.fr>

6600 2003-10-03 Akim Demaille <akim@epita.fr>
6602 * configure.ac: Quotation and formatting changes.

6623 * lib/Autom4te/XFile.pm: Use Errno.
6624 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
6625 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

6637 have been created when invoking the compiler.

6651 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6652 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6653 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6655 2003-09-26 Akim Demaille <akim@epita.fr>
6657 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6658 directory for AC_CONFIG_COMMANDS' first argument exists.
6659 This makes valid the invocation of _AC_SRCPATH that follows.
6660 Reported by Eric Sunshine.
6661 * doc/autoconf.texi (Configuration Commands): Adjust.
6663 2003-09-26 Akim Demaille <akim@epita.fr>
6665 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6666 Reported by Ralf Corsepius.

6670 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6671 arguments.

6682 2003-09-26 Akim Demaille <akim@epita.fr>
6684 The test suite are sometimes assigning timings incorrectly.
6685 Reported by Henk Krus.
6686 Diagnosed by Nicolas Joly.
6688 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6689 AT_help_all.
6690 Instead of making AT_help a sequence of assignments to grow
6691 $at_help_all, just make AT_help_all be the growing contents of
6692 $at_help_all, and make a single assignment in...
6693 (AT_INIT): here.
6694 (at_times_skip): Flip the meaning and rename as...
6695 (at_times_p): this.
6696 (AT_INIT): When summarizing the test that ran, remove
6697 $at_times_file after use, and check it is present before trying to
6698 use it.

6706 (ifnames): chmod -w.
6707 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6708 executables, not bin/ executables! Otherwise all the magic needed
6709 to find non installed files is turned off. This caused a failure
6710 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6711 as found in its environment (sent by tests/autoreconf): pointing
6712 to bin/autom4te that could not find its files.
6713 * tests/mktests.sh: Force the replacement of generated files, for
6714 the sake of "mv" program that are interactive when overwriting a
6715 -w file.

6726 Trivial change to support GCC's configuration procedure.
6727 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6728 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6729 about inconsistency if the preprocessor is set to give errors for
6730 any warning.

6733 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

6749 2003-09-12 Akim Demaille <akim@epita.fr>
6751 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6752 not asm/types.h.
6754 2003-09-11 Akim Demaille <akim@epita.fr>
6756 * doc/autoconf.texi (Header Portability): linux/random.h.
6757 From Peter Hendrickson.
6759 2003-09-10 Akim Demaille <akim@epita.fr>
6761 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6762 willing to edit the output files.
6764 2003-09-10 Akim Demaille <akim@epita.fr>
6766 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6767 and AC_FC_FREEFORM.
6768 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6769 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

6784 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6785 Improve the accuracy of the wording about obsolescence.
6786 From a suggestion by Ian Lance Taylor in
6787 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6789 2003-09-05 Paul Eggert <eggert@twinsun.com>
6791 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6792 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6794 2003-09-04 Akim Demaille <akim@epita.fr>
6796 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6797 AC_FUNC_WAIT3.
6799 2003-09-04 Akim Demaille <akim@epita.fr>
6801 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6802 (freeze): When exiting, use $exit_code.
6803 * lib/autoconf/fortran.m4: Comment changes.
6805 2003-09-04 Akim Demaille <akim@epita.fr>
6807 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6809 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6811 Add support for newer Fortran dialects. The F77 interface is
6812 unchanged, and continues to support Fortran 77. New FC macros
6813 correspond to all the old F77 macros, with output variables FC,
6814 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6815 available dialect, but older dialects can be specified. There are
6816 new macros AC_FC_SRCEXT to set the source extension, and
6817 AC_FC_FREEFORM to accept free-form source files.
6819 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6820 New macros.
6821 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
6822 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
6823 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
6824 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

6832 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
6833 AC_FC_SRCEXT, AC_FC_FREEFORM):
6834 New macros.
6835 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
6836 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
6837 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6838 Rewrite in terms of the above.
6839 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6840 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

6842 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
6844 2003-09-02 Paul Eggert <eggert@twinsun.com>
6846 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6847 Document problems with timestamp resolution that 'make', 'cp -p', and
6848 'touch -r' have.
6850 2003-08-27 Akim Demaille <akim@epita.fr>
6852 * tests/m4sugar.at (cross_warning): Make sure to enable the
6853 output, so that we can track spurious m4sugar output.
6854 * tests/local.at: Require 2.57.
6855 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6856 are defaulted by AT_CHECK anyway.
6857 Use AT_CHECK_AUTOM4TE.
6858 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6859 missing dnl.
6861 2003-08-27 Akim Demaille <akim@epita.fr>
6863 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6864 when -Wobsolete is set.
6865 Set it on by default.
6866 Suggested by Klee Dienes.
6868 2003-08-27 Akim Demaille <akim@epita.fr>
6870 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More

6877 after AC_OUTPUT.
6879 2003-08-25 Akim Demaille <akim@epita.fr>
6881 * config/announce-gen, GNUmakefile, Makefile.maint: Update from

6903 * Makefile.maint (local-check): Rename as...
6904 (local-checks-available): this.
6905 (local-check): New.
6907 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
6908 * configure.ac: Require Automake 1.7.6.
6910 2003-08-22 Akim Demaille <akim@epita.fr>
6912 Output stack traces in warnings.
6914 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
6915 Replace the former...
6916 (m4_warn): Pass the call stack to _m4_warn.
6917 * bin/autom4te.in: Adjust to output the call stack.
6918 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6920 2003-08-22 Akim Demaille <akim@epita.fr>
6922 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
6923 * bin/autom4te.in: Adjust.
6925 2003-08-21 Akim Demaille <akim@epita.fr>
6927 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6928 (&verbose): Remove.
6929 (&getopt): Adjust the note and verb channels, depending upon
6930 --verbose.
6931 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
6932 * bin/autoupdate.in: Adjust.
6933 Use &verb, not &verbose.
6935 2003-08-21 Akim Demaille <akim@epita.fr>
6937 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6938 &parse_WARNINGS.
6939 ($help): Use Autom4te::ChannelDefs::usage.
6940 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6941 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6943 2003-08-21 Akim Demaille <akim@epita.fr>
6945 First stab at preserving warnings between calls to autom4te,
6946 including when the cache is used.
6948 There are still several issues: (i) there are too many runs of m4
6949 (one for include, one for warnings, and some more), (ii) warnings
6950 spreading on several lines are not handled gracefully, (iii) the
6951 code meant to have the call stack display for errors does not work
6952 (its handling should move from m4 to autom4te).
6954 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6955 Use them.
6956 (@preselect): Add m4_warn.
6957 ($exit_status): Remove, use $exit_code.
6958 ($help): Use Autom4te::ChannelDefs::usage.
6959 (&handle_m4): No longer define the m4_warnings.
6960 At each run, extract and report the warnings.
6961 Always cache the result, including if the exit status is on
6962 failure, since if nothing changes, we should result in the same
6963 failure, hence we can use the cache.
6964 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6965 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6966 Remove.
6967 (m4_warn): Redefine as a do-nothing: it is its invocation that
6968 matters, as warnings are now reported via traces.
6969 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6970 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6971 the latter reveals calls to the former.
6973 Adjust the tests.
6975 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6977 2003-08-21 Akim Demaille <akim@epita.fr>
6979 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6980 Use them.
6982 2003-08-21 Akim Demaille <akim@epita.fr>
6984 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6985 forward order.
6986 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6987 (&parse_warnings): Accept a list of warning requests.
6988 (&usage): Return a string, not a side effect.
6989 (cross): New warning category.
6991 2003-08-21 Akim Demaille <akim@epita.fr>
6993 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6994 (&require_configure_ac): Accept an optional directory argument.
6995 ($configure_ac): Remove.
6996 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6997 (&catfile): Remove.
6998 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6999 * bin/autoscan.in: Adjust.
7001 2003-08-20 Akim Demaille <akim@epita.fr>
7003 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7004 Reported by Alexandre Duret-Lutz.
7006 2003-08-20 Akim Demaille <akim@epita.fr>
7008 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7009 * bin/autom4te: Adjust.
7010 In particular, be Autoconf tools are really silent when properly
7011 working, bind the verbosity of the 'note' channel to $verbose.
7012 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7013 (&xsystem, &contents): Remove, since they are exported by...
7014 * lib/Autom4te/FileUtils.pm: this.
7015 More perldoc.
7016 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7017 * lib/Autom4te/FileUtils.pm: here.
7019 2003-08-20 Akim Demaille <akim@epita.fr>
7021 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7022 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
7023 from CVS Automake.
7025 2003-08-20 Akim Demaille <akim@epita.fr>
7027 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
7028 (autom4te-update): New.
7029 * Makefile.cfg (update): Bind autom4te-update.
7031 2003-08-19 Derek Price <derek@ximbiot.com>
7033 * lib/autotest/general.m4: Comment various HELP_* diversions.
7034 (PARSE_ARGS_BEGIN): New section for option parsing related

7047 * lib/autom4te.in (Automake-preselections): Preselect
7048 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
7049 and m4_sinclude.
7051 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7053 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
7054 (Autoconf-without-aclocal-m4): ... this new language.
7055 * doc/autoconf.texi (autom4te Invocation): Mention
7056 Autoconf-without-aclocal-m4.

7061 RUN-IF-PASS optional arguments.

7070 STDOUT & STDERR arguments.
7072 2003-08-14 Derek Price <derek@ximbiot.com>
7074 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7075 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7076 shorter column three. Add DESCRIPTION to log file content.
7078 2003-08-13 Derek Price <derek@ximbiot.com>
7080 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7081 output.
7083 2003-08-12 Derek Price <derek@ximbiot.com>
7085 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7086 (AT_CHECK_NOESCAPE): Move core functionality to...
7087 (_AT_CHECK): ...this new macro.
7089 2003-08-07 Derek Price <derek@ximbiot.com>
7091 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7092 (AT_CHECK_NOESCAPE): ...to this new macro.
7094 2003-07-31 Paul Eggert <eggert@twinsun.com>
7096 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7097 in Bash 2.01. Problem reported by Brian Gough in
7098 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7100 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7102 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7103 -lcrt1.o, for OS X. (trivial change)
7105 2003-07-07 Paul Eggert <eggert@twinsun.com>
7107 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7108 inside '#ifndef __cplusplus'. Problem reported by
7109 Bob Friesenhahn.
7111 2003-07-06 Bill Clarke <llib@computer.org>
7113 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7114 'long', not 'int', for benefit of Sun's recent C++ compilers
7115 (trivial change). See:
7116 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7117 (This really should be 'intptr_t', not 'long', but that would
7118 take more work.)
7120 2003-06-25 Akim Demaille <akim@epita.fr>
7122 * lib/Makefile.am (autom4te.cfg): Make it read only.
7123 Depend on Makefile since it contains substitutions.
7124 From Paolo Bonzini.
7125 * lib/autom4te.in (args): Add local.at? for Autotest args.
7126 This change was made on autom4te.cfg which is generated.
7127 Reported by Raja R. Harinath.
7129 2003-06-25 Akim Demaille <akim@epita.fr>
7131 * doc/autoconf.texi (Header Portability): sys/mount.h.
7132 From Gareth McCaughan.
7134 2003-06-23 Akim Demaille <akim@epita.fr>
7136 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7137 not all of them. This fixes 1. the fact that when testing
7138 Autoconf there are many many config.log, 2. the incorrect use of
7139 top_srcdir to find config.log.
7140 Don't mix the detailed output of failed test with the summary of
7141 failures. Rather, append detailed log afterwards.
7143 2003-06-23 Akim Demaille <akim@epita.fr>
7145 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7146 always run: output config.log on $at_group_log.
7148 2003-06-23 Akim Demaille <akim@epita.fr>
7150 * tests/torture.at (#define header templates): Don't use quotes in
7151 C++ comments as it puzzles Emacs' sh font-lock-mode.
7153 2003-06-23 Akim Demaille <akim@epita.fr>
7155 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7156 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7157 * tests/atspecific.m4: Rename as...

7159 * tests/suite.at: Move the globals into...
7160 * tests/local.at: here.
7161 * tests/Makefile.am: Adjust.
7162 * doc/autoconf.texi (testsuite Scripts): Adjust.
7164 2003-06-21 Kevin Ryde <user42@zip.com.au>
7166 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7167 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7168 ensuring we add -std1 for full-ANSI.
7170 * doc/autoconf.texi (hdrindex): New macro.
7171 Add index entries for portability of various standard header files.
7173 2003-06-20 Akim Demaille <akim@epita.fr>
7175 * configure.ac: Bump to 2.57b.
7177 2003-06-20 Akim Demaille <akim@epita.fr>
7179 Version 2.57a.
7181 2003-06-20 Akim Demaille <akim@epita.fr>
7183 * bin/autom4te.in: Don't rely on $HOME being defined.
7184 Reported by Marc Espie as PR/233.
7186 2003-06-20 Akim Demaille <akim@epita.fr>
7188 * lib/autotest/general.m4: Use at_times_file only if used.
7189 From Nicolas Joly.
7191 2003-06-20 Akim Demaille <akim@epita.fr>
7193 * config/config.guess, config/config.sub, config/elisp-comp,
7194 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7195 Update from masters.
7197 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7199 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7200 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7201 (TEST_SCRIPT): New diversion.
7202 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7203 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7204 (AT_INIT): Support for expected failures.
7206 2003-06-02 Akim Demaille <akim@epita.fr>
7208 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7209 changes.
7210 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7211 Autoconf nor Automake.
7212 (&contents): New, from Automake.
7213 PODify.
7215 2003-05-28 Paul Eggert <eggert@twinsun.com>
7217 * NEWS, doc/autoconf.texi (Particular Functions),
7218 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7219 is the inverse of localtime.
7221 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7223 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7224 (handle_exec_errors): New function. Work around $! being
7225 altered by WEXITSTATUS.
7226 (xqx, xsystem): Use handle_exec_errors.
7228 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7230 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7231 Do not call `_exit()', simply modify `$?'.
7232 (xsystem): Reset $! before running system, and check it afterward.
7233 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7234 63 for version mismatches.
7236 2003-05-23 Akim Demaille <akim@epita.fr>
7238 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7239 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7240 the middle of a line).
7241 * lib/m4sugar/m4sugar.m4: Likewise.
7242 Remove useless spaces in comments.
7244 2003-05-23 Akim Demaille <akim@epita.fr>
7246 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7247 exit 63, so that we (or Automake's "missing") can tell the
7248 difference with a plain failure.
7249 * doc/autoconf.texi (Notices): Adjust.
7251 2003-05-23 Akim Demaille <akim@epita.fr>
7253 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7254 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7255 White spaces cleanup.
7257 2003-05-22 Jim Meyering <jim@meyering.net>
7258 Paul Eggert <eggert@twinsun.com>
7260 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7261 Remove `#include <stdlib.h>' from the list; we should never
7262 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7263 resulting namespace pollution would cause other tests to fail.
7264 Configure scripts run with some older versions of g++ and HP's
7265 aCC would fail due to such an #include. Problems reported by
7266 Matthew Mueller in <http://bugs.debian.org/120704> and by
7267 Keith Bostic in
7268 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7269 In the test, use the test declaration before including <stdlib.h>,
7270 as that's closer to how it'll be used.
7272 2003-05-23 Akim Demaille <akim@epita.fr>
7274 * doc/autoconf.texi (Header Portability): ucred.h.
7275 From Ian Redfern.
7277 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7279 Overhaul Autotest's logging: generate separate log files
7280 in testsuite.dir/NNN/testsuite.log, and append them to
7281 testsuite.log instead of re-running the test verbosely.
7283 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7284 file descriptor, write 0 to at_status_file instead of setting
7285 at_status=0, initialize some new variables (at_status_file,
7286 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7287 to rerun the tests, instead append the at_group_log to the
7288 at_suite_log when a test fails.
7289 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7290 with the AS_MESSAGE_LOG_FD redirected to stdout.
7291 (AT_CLEANUP): save the output status in $at_status_file
7292 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7293 its original place.
7294 (AT_CHECK): since tests are run with a redirected stdout,
7295 and used to be re-run in verbose mode, turn some $at_verbose
7296 into echo, and don't redirect the output of testing stdout
7297 and stderr.
7299 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7300 the name of the debugging directory and information about
7301 its contents.
7303 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7305 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd

7418 and truncate.
7420 2003-05-06 Akim Demaille <akim@epita.fr>
7422 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7423 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7424 by aclocal.m4 is changed it might require the importing of another
7425 m4 extension file, i.e., aclocal must be run.
7427 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7428 (&parse_args): Use --force with aclocal if required and supported.

7436 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7437 argument instead of a file name, so that the request file remains
7438 open during the whole autom4te run.
7439 ($icache_file): New.
7440 (&freeze): Lock the $icache_file.
7442 2003-04-29 Derek Price <derek@ximbiot.com>
7444 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7445 seperator with m4_append_uniq(). It doesn't work.
7446 (AT_CLEANUP): Add `;' to end of at_help_all.
7447 (AT_INIT): Allow --keywords to be specified more than once. When
7448 grepping $at_help_all for keywords, use the field and keyword
7449 seperators to ensure a complete keyword match. Alter at_prev handling
7450 to support the new --keywords behavior.
7452 2003-04-27 Karl Berry <karl@freefriends.org>
7454 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7455 align better with others. I also made some of the individual
7456 entries on one line, for brevity and to make it easier for me to
7457 sort my dir-example file in the Texinfo distribution :).

7677 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7678 innocuous variant befor including <limits.h> or <assert.h>. This
7679 works around a bug reported by Albert Chin: HP-UX 11i
7680 (and earlier versions) have a <limits.h> that declares
7681 gettimeofday and many other functions.
7683 2002-12-03 Paul Eggert <eggert@twinsun.com>

7691 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7692 nontrivially in main's body, so that f's external declaration is
7693 not optimized away in AIX. This should fix the bug reported by
7694 Martin Frydl in
7695 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7697 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7698 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7699 defined, to support freestanding compilers. This should fix the
7700 bug reported by Momchil Velkov in
7701 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7703 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7704 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

7709 * Makefile.maint (www-gnu): New macro.
7710 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7711 the location has moved.
7713 2002-12-02 Martin Frydl <martin@systinet.com>
7715 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7716 \(.*\) match is too long and there is something more to be checked.
7717 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

7737 2002-11-14 Akim Demaille <akim@epita.fr>
7739 * Makefile.maint: Sync with Bison, i.e.:
7740 (po-check): Scan .l and .y files instead of the
7741 .c and the .h files that they generate. This fixes the bug
7742 reported by Tim Van Holder in:
7743 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7744 Look for N_ as well as for _. Try to avoid matching #define for
7745 N_ and _.
7746 From Paul Eggert.

7772 config.status -q option.
7774 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

7799 Reported by Ezra Peisach.
7801 2002-11-05 Akim Demaille <akim@epita.fr>
7803 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7804 Remove.
7805 We _have_ to stop using the old compatibility scheme that tried to
7806 avoid useless backslashes because Libtool 1.4.3 contains a
7807 AC_DEFINE([error_t], [int],
7808 [Define to a type to use for \`error_t' if it is not
7809 otherwise available.])
7810 We _have_ to quote the single quote and backslashes with \. The
7811 old compatibility scheme saw that ` was backslashed, and therefore
7812 did not quote the single quote. Hence before this patch, Autoconf
7813 was not compatible with Libtool.
7815 2002-11-04 Paul Eggert <eggert@twinsun.com>

7887 Problem reported by Bruno Haible.
7889 2002-10-29 Akim Demaille <akim@epita.fr>

8203 longer required can still cause errors.
8204 Reported by Alexandre Duret-Lutz.
8206 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

8227 if some file was changed instead of `print'.

8256 * tests/torture.at (AC_ARG_VAR): Have configure report the value
8257 of `precious'.
8259 2002-10-11 Akim Demaille <akim@epita.fr>
8261 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
8262 file name to enable parallel executions.
8263 From Sam Varshavchik.
8265 2002-10-08 Akim Demaille <akim@epita.fr>
8267 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8268 aclocal invocation, as Gettext macros might not be visible to
8269 aclocal.
8270 Instead of blindly running autopoint, scan configure.ac (not the
8271 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8272 Reported by Paul D. Smith.
8274 2002-10-08 Paul Eggert <eggert@twinsun.com>
8276 Work around problems found when POSIXLY_CORRECT=1 is set.
8277 None of this seems to have anything to do with POSIX, really,
8278 but it's how Perl getopt works.
8279 * bin/autom4te.in (parse_args): Configure GetOpt with
8280 "permute", too.
8281 * doc/autoconf.texi (Invoking autom4te):
8282 --warning -> --warnings.
8283 * lib/autom4te.in: --warning -> --warnings.
8285 2002-09-28 Akim Demaille <akim@epita.fr>
8287 * doc/autoconf.texi (autom4te.cache): New section.
8289 2002-09-28 Akim Demaille <akim@epita.fr>
8291 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
8292 (Automake-preselections): Update.
8293 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
8295 2002-09-28 Akim Demaille <akim@epita.fr>
8297 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
8298 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
8299 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8300 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
8302 2002-09-28 Akim Demaille <akim@epita.fr>
8304 * tests/torture.at (Configuring subdirectories): Be robust to
8305 users who use config.site to require for a cache: in this case,
8306 the two last configure runs, using two different sets of
8307 arguments, trigger a legitimate error.
8309 2002-09-28 Akim Demaille <akim@epita.fr>
8311 * tests/m4sh.at (Functions Support, Functions and return Support):
8312 New.
8314 2002-09-28 Akim Demaille <akim@epita.fr>
8316 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
8317 autoheader are Perl programs.
8318 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
8319 (autom4te): Specify that the sources are in the $srcdir.
8320 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8322 2002-09-28 Akim Demaille <akim@epita.fr>
8324 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
8325 (tm_zone): Move their rules to...
8326 * lib/autoconf/types.m4: here, using AN_ macros.
8327 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8328 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8329 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8330 * lib/autoconf/programs.m4: here.
8331 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
8332 (ETAGS_FOR_AUTOCONF): New.
8333 Use it.
8335 2002-09-28 Akim Demaille <akim@epita.fr>
8337 * lib/autoconf/autoscan.m4: New file.
8338 * lib/autoconf/autoconf.m4: Include it.
8339 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
8340 that were listed in the original autoscan.list.
8341 * lib/autoconf/headers.m4: Similarly with headers.
8342 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8343 (.m4.m4f): Don't pass --prepend-include, since that's done by
8344 tests/autom4te itself.
8345 * lib/autoscan/Makefile.am: Include freeze.mk.
8346 (autoscan.list): New target --this file is no longer a source.
8347 (autoscan.pre): New file.
8349 2002-09-28 Akim Demaille <akim@epita.fr>
8351 * bin/autoscan.in (@kinds): Make them singular.
8352 Adjust all uses.
8353 (&init_tables): When --debug, report the list of rules to ease
8354 tracking changes in autoscan.list.
8355 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8357 2002-09-28 Akim Demaille <akim@epita.fr>
8359 * lib/autoscan/functions, lib/autoscan/headers,
8360 * lib/autoscan/identifiers, lib/autoscan/makevars,
8361 * lib/autoscan/programs: Merge into...
8362 * lib/autoscan/autoscan.list: this.
8363 * bin/autoscan.in (&init_tables): Adjust.
8365 2002-09-28 Akim Demaille <akim@epita.fr>
8367 * lib/autoscan/functions, lib/autoscan/headers,
8368 * lib/autoscan/identifiers, lib/autoscan/makevars,
8369 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8370 `functions' line is now prefixed with `function:'.
8371 * bin/autoscan.in (&init_tables): Adjust.
8373 2002-09-28 Akim Demaille <akim@epita.fr>
8375 From now on, autoscan files must always map a macro name to a
8376 word: there is no `default' macro for autoscan.
8378 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8379 all.
8380 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8381 explicit.
8383 2002-09-28 Akim Demaille <akim@epita.fr>
8385 * bin/autoscan.in (%c_keywords): Remove.
8386 (&used): Keep only track of the words we might be interested in.
8387 (&output_kind): It is no longer needed to look for non active
8388 checks.
8390 2002-09-27 Akim Demaille <akim@epita.fr>
8392 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
8393 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
8394 * lib/autoscan/functions: Adjust.
8395 * doc/autoconf.texi (Particular Functions): Adjust.
8397 2002-09-27 Akim Demaille <akim@epita.fr>
8399 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8400 from /tmp.
8401 Thanks to Bill Moseley and Paul Eggert.
8402 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8403 the tmpdir must be created.
8404 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8405 dir be in the build tree, instead of $TMPDIR.
8407 2002-09-27 Akim Demaille <akim@epita.fr>
8409 * bin/autoscan.in: Improve the comments.
8410 (&parse_args): Drop obsolete undocumented options.
8411 (&output_kind): Output warnings.
8412 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
8413 (getwd): Trigger a warning.
8415 2002-09-26 Akim Demaille <akim@epita.fr>
8417 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8418 Reported by Ralf Corsepius.
8419 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8421 2002-09-26 Akim Demaille <akim@epita.fr>
8423 Single suffix rules and seperated dependencies are not portable.
8425 * doc/autoconf.texi (Installation Directory Variables): Update.
8426 (Limitations of Make): Some about `Single Suffix Rules and
8427 Separated Dependencies'.
8428 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8429 (ifnames, autoscan, autom4te): Un-factor into several rules.
8431 2002-09-25 Paul Eggert <eggert@twinsun.com>
8433 * BUGS (Interoperability bugs): New section. Mention libtool
8434 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8436 2002-09-24 Paul Eggert <eggert@twinsun.com>
8438 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8439 make handles suffix-rules differently from GNU make.
8441 * bin/Makefile.am (SUFFIXES, .in): Remove.
8442 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8443 Move the body of the old .in rule here.
8445 2002-09-16 Akim Demaille <akim@epita.fr>
8447 i960 compilers create `b.out' files by default.
8448 Reported by Ralf Corsepius.
8450 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8451 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8453 2002-09-13 Paul Eggert <eggert@twinsun.com>
8455 * doc/autoconf.texi (Particular Headers): Remove obsolete
8456 reference to `struct timezone' in the description of
8457 AC_HEADER_TIME.
8459 2002-09-13 Akim Demaille <akim@epita.fr>
8461 Version 2.54.
8463 * config/config.sub, config/config.guess: Update.
8464 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8465 * Makefile.am: Adjust.
8467 2002-09-13 Akim Demaille <akim@epita.fr>
8469 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8470 reading config.log when the compiler is rejected.
8471 Suggested by Guido Draheim.
8473 2002-09-13 Akim Demaille <akim@epita.fr>
8475 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8476 (chdir_init) might hang when stat'ing mounted directories.
8477 Reported by Vance Shipley.
8479 2002-09-12 Akim Demaille <akim@epita.fr>
8481 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8482 the lists.
8484 2002-09-12 Akim Demaille <akim@epita.fr>
8486 * doc/autoconf.texi (Defining Symbols): Present two different
8487 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8488 difference between 1 argument calls, and 2-3 argument calls.
8490 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8492 * doc/autoconf.texi: Review grammar and punctuation.
8494 2002-09-11 Paul Eggert <eggert@twinsun.com>
8496 * doc/autoconf.texi: Fix minor formatting, spelling, and
8497 grammatical typos.
8498 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8499 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8500 is obsolescent.
8502 2002-09-11 Akim Demaille <akim@epita.fr>
8504 * doc/autoconf.texi (Questions): Rename as...
8505 (FAQ): this.
8506 (Defining Directories): New.
8508 2002-09-09 Akim Demaille <akim@epita.fr>
8510 * doc/autoconf.texi (Making testsuite Scripts): Update.
8511 Suggested by Nishio Futoshi.
8513 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8515 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8516 plain `@' is wanted.
8518 2002-09-09 Akim Demaille <akim@epita.fr>
8520 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8521 `duplicates', since the algorithm was too naive and could keep
8522 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8523 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8524 Reported by Ralf Corsepius.
8525 * tests/torture.at (Configuring subdirectories): Exercise these
8526 cases.
8528 2002-09-09 Akim Demaille <akim@epita.fr>
8530 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8531 looking for a replacement file.
8532 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8533 directory is relative.
8534 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8535 directory definition.
8536 Reported by Andreas Schwab and Jim Meyering.
8538 2002-09-06 Akim Demaille <akim@epita.fr>
8540 * doc/autoconf.texi (Setting Output Variables): Clarify what
8541 precious variables are.
8542 Suggested by Pontus Skoeld.
8544 2002-09-05 Akim Demaille <akim@epita.fr>
8546 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8547 (ifnames, autoscan, autom4te): Since we don't only depend on
8548 configure.ac variables (such as VERSION etc.), but also on prefix
8549 and so forth, depend on Makefile, not configure.ac.
8550 Reported by Alexandre Duret-Lutz.
8551 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8553 2002-09-05 Kevin Ryde <user42@zip.com.au>
8555 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8556 doesn't seem to be confined to ia64, just say "some versions".
8558 2002-09-04 Akim Demaille <akim@epita.fr>
8560 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8561 Automake 1.6c.
8562 * Makefile.am (maintainer-clean-local): Remove.
8563 (MAINTAINERCLEANFILES): Remove COPYING.
8565 2002-09-03 Paul Eggert <eggert@twinsun.com>
8567 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8568 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8569 Brinkmann.
8571 2002-09-03 Akim Demaille <akim@epita.fr>
8573 * configure.ac: Bump to 2.53d.
8574 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8575 as of today, on Automake's team suggestion.
8577 2002-09-03 Akim Demaille <akim@epita.fr>
8579 Version 2.53c.
8581 2002-09-02 Akim Demaille <akim@epita.fr>
8583 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8584 SITE_MACRO_DIR.
8585 * configure.ac: Disable SITE_MACRO_DIR.
8587 2002-09-02 Jim Meyering <meyering@lucent.com>
8589 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8590 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8591 Also, tweak grammar: s/make sure to/be sure to/.
8593 2002-09-02 Paul Eggert <eggert@twinsun.com>
8595 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8596 directory names are generally preferable to physical names.
8598 2002-09-02 Akim Demaille <akim@epita.fr>
8600 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8601 Reported by Raja R. Harinath.
8602 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8603 * bin/autoupdate.in: Use error instead of die.
8605 2002-09-01 Paul Eggert <eggert@twinsun.com>
8607 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8608 ordinary shell concatenation rather than echo+tr+sed command that
8609 runs afoul of a long-line-related sed bug in Solaris 8.
8611 * bin/autoheader.in (parse_args): --warning -> --warnings.
8613 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8614 stdout, as traditional "ls" does.
8615 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8616 _AC_COMPILER_EXEEXT_O): Likewise.
8617 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8619 * bin/autoconf.as: Add --prepend-include option. This patch was
8620 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8621 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8623 * bin/autoconf.in, configure: Regenerate.
8625 * doc/autoconf.texi (Special Shell Variables): Mention
8626 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8628 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8629 MAILPATH and set PS1, PS2, PS4 to default values, to work
8630 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8631 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8632 the Autoconf documentation specifies; fall back to "unset" only if
8633 this fails. Use a shell for-loop for this rather than an m4 loop,
8634 to shorten the output script.
8636 2002-08-30 Paul Eggert <eggert@twinsun.com>
8638 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8639 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8640 for the CDPATH problem. Document PWD.
8641 (Limitations of Builtins): Document the problem that "cd $foo" and
8642 "ls $foo" may refer to different directories in shells conforming
8643 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8644 example, since the old example is now out of date.
8646 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8647 FOO" and "ls FOO" talk about different directories; this catches
8648 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8649 spaghetti.
8651 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8652 of rolling our own unset.
8653 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8654 in practice we needn't worry about CDPATH if unset doesn't work.
8656 * Makefile.in, aclocal.m4, bin/Makefile.in,
8657 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8658 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8659 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8660 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8661 tests/Makefile.in: Regenerate with Automake 1.6.3.
8663 * config/config.guess, config/config.sub, config/mkinstalldirs:
8664 Update.
8666 * configure: Regenerate with self.
8668 2002-08-30 Kevin Ryde <user42@zip.com.au>
8670 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8671 default output.
8673 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8675 * bin/autom4te.in (Request::load): Correctly test for "do" read
8676 failure.
8678 2002-08-29 Akim Demaille <akim@epita.fr>
8680 * lib/Autom4te/General.pm (&xqx): New.
8681 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8682 hand, which is not portable.
8683 (&error): New.
8684 * bin/autom4te.in: Use them.
8685 Use &error instead of die.
8686 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8687 Adjust.
8689 2002-08-17 Paul Eggert <eggert@twinsun.com>
8691 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8692 default list of compilers to try, since it was long ago superseded
8693 by the ksh fc builtin. Suggested by Steven G. Johnson.
8695 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8697 * doc/autoconf.texi (Invoking autom4te): End the option table,
8698 fixing a bug introduced by the previous patch.
8699 (Limitations of Make): Add a 'target lookup' subentry in the
8700 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8702 2002-07-29 Mark D. Roth <roth@feep.net>
8704 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8705 options and use $AUTOM4TE_PATH.
8706 * doc/autoconf.texi: Remove documentation of autom4te
8707 --include-envvar and --site-macro-subdir options and document
8708 use of $AUTOM4TE_PATH.
8709 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8710 arguments from each language section.
8712 2002-07-29 Paul Eggert <eggert@twinsun.com>
8714 * doc/install.texi: Include copyright symbol in copyright notice.
8716 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8717 Replace with:
8718 (AM_MAKEINFOFLAGS): New macro.
8719 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8720 * Makefile.am (INSTALL): Use the new macros.
8721 Use -o rather than --output, since "missing" does not grok --output.
8723 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8725 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8726 comments do not always work. Never trust the exit status of
8727 `make -k'.
8729 2002-07-24 Kevin Ryde <user42@zip.com.au>
8731 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8732 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8734 2002-07-23 Paul Eggert <eggert@twinsun.com>
8736 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8737 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8738 apparently treats PATH="nonexistent" as if it contained ".".
8739 Bug reported by Stefan `Sec' Zehl.
8741 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8743 * doc/autoconf.texi (Limitations of Make): Mention the special

8865 2002-06-27 Paul Eggert <eggert@twinsun.com>
8867 * config/install-sh: Quote $src. Prefer || to test's -o option,
8868 as per "Limitations of Builtins".

8930 2002-06-07 Akim Demaille <akim@epita.fr>
8932 * bin/autom4te.in (warn_forbidden): When rejecting a token,

8941 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

8954 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp

8995 version of Autoconf that is discussed.
8997 2002-05-22 Paul Eggert <eggert@twinsun.com>
8999 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
9000 from the default list of compilers to try. Suggested by
9001 Kate Hedstrom.
9002 * NEWS: Document the above.
9003 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
9005 2002-05-17 Paul Eggert <eggert@twinsun.com>
9007 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9008 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9009 This improves on an earlier suggestion by H. Peter Anvin.
9011 2002-05-16 Paul Eggert <eggert@twinsun.com>
9013 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9014 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9015 Both macros now accept an optional source-dir arg.
9016 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9018 * NEWS: Document this.
9019 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9021 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9022 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9023 not for GNU extensions; this undoes part of the 2000-11-03 change,
9024 reverting to 2.13-compatible behavior.
9025 Add new optional argument DIR.
9026 (AC_FUNC_FNMATCH_GNU): New macro.
9028 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9030 2002-05-08 Paul Eggert <eggert@twinsun.com>
9032 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9033 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9034 and it causes a 'test' syntax error if it fails.
9035 Bug reported by Stephen Gildea.
9037 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9038 If prototypes are supported, use them to check this at compile-time,
9039 instead of trying to check it at run-time. If we must do a run-time
9040 check, assume that setvbuf is standard when cross-compiling, as
9041 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9042 Bug reported by Paul D. Smith.
9044 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9045 argument specifying location of getloadavg.c. This removes a
9046 FIXME. This idea was taken from Jim Meyering's implementation in
9047 textutils.
9048 * doc/autoconf.texi (Particular Functions): Document this.
9049 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9050 that's what the code does; this fixes a bug reported by
9051 Paul D. Smith.
9053 2002-05-03 Akim Demaille <akim@epita.fr>
9055 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9056 autopoint instead of gettextize.
9057 ($uses_alocal): Rename as...
9058 ($uses_aclocal): this.
9059 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9060 Suggested by Bruno Haible.
9062 2002-05-03 Akim Demaille <akim@epita.fr>
9064 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9066 2002-04-29 Paul Eggert <eggert@twinsun.com>
9068 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9069 files to be 1 second older; just set them to be the same time.
9070 Also, sleep 1 second after the first aclocal, to work around
9071 problems with sub-second time stamps on the input files.
9073 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9075 * doc/autoconf.texi: Mention "set -e -x" lossage
9076 under node "Limitations of Builtins".
9078 2002-04-29 Akim Demaille <akim@epita.fr>
9080 * doc/install.texi: Better wording for setting variables when
9081 running configure.
9082 From Christian Cornelssen.
9084 2002-04-29 Akim Demaille <akim@epita.fr>
9086 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9087 of lack of $LINENO support, then the test will compare the $LINENO
9088 in testsuite vs. the lineno in the test file. This is wrong, of
9089 course.
9090 Be sure to protect it.
9091 Reported by Patrick Welche.
9093 2002-04-25 Akim Demaille <akim@epita.fr>
9095 * doc/autoconf.texi (Obsolete Macros): Typo.
9096 Reported by Vladimir Volovich.
9098 2002-04-25 Akim Demaille <akim@epita.fr>
9100 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9101 than some of the input files, hence, on the second run of aclocal,
9102 if some of its input are younger, make them older.
9103 Suggested by Paul Eggert.
9105 2002-04-25 Akim Demaille <akim@epita.fr>
9107 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9108 Thanks to Paul Eggert.
9110 2002-04-25 Akim Demaille <akim@epita.fr>
9112 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9113 and ac_subst_vars be sh variables containing the list of
9114 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9115 DEFAULT diversion.
9116 (_AC_INIT_PREPARE): Use them to log them.
9117 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9118 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9119 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9120 _AC_SUBST_FILES and _AC_SUBST_VARS.
9121 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9123 2002-04-24 Akim Demaille <akim@epita.fr>
9125 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9126 autoheader, so that automake does not complain about a missing
9127 config.h.in that was to be created.
9129 2002-04-23 Akim Demaille <akim@epita.fr>
9131 * bin/autoheader.in (parse_args): --warning takes an argument.
9132 Fixes PR/220.

9183 * doc/autoconf.texi: Follow the outline suggested in the GNU
9184 Sample Texts sections of the Texinfo 4.2 manual. Most
9185 importantly, this makes sure that the copyright notices appear in
9186 all output formats. You probably need Texinfo 4.2 to generate

9231 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9232 part into...
9233 (_AS_PREPARE): this new macro.
9234 (AS_PREPARE): New.
9235 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9236 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9238 Adjust Autoconf and Autotest.
9240 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9241 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9242 * lib/autotest/general.m4 (AT_INIT): Likewise.
9243 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9244 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9245 AS_SHELL_SANITIZE.
9247 Use this M4sh to generate Autoconf's shell scripts.
9249 * tests/wrapsh.as: New, precursor of wrapsh.in.
9250 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9251 on Autotest and M4sh.
9252 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9253 (wrapsh.in): New target.
9254 * bin/autoconf.as: New, precursor of autoconf.in.
9255 (autoconf.in): New target.
9257 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
9259 * doc/autoconf.texi (Limitations of Make): Mention the issue
9260 with indented comments in rules.
9262 2002-04-09 Andreas Schwab <schwab@suse.de>
9264 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9265 ac_top_builddir when setting ac_abs_top_builddir.
9267 2002-04-06 Kevin Ryde <user42@zip.com.au>
9269 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9270 (Portable Shell): Cross reference to Systemology.
9272 2002-04-05 Akim Demaille <akim@epita.fr>
9274 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9275 directories when descending in a SUBDIRS.
9276 Reported by Ezra Peisach.
9278 2002-04-04 Andreas Schwab <schwab@suse.de>
9280 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9281 contains no literal separators.
9283 2002-04-03 Akim Demaille <akim@epita.fr>
9285 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9286 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9287 Use dnl, not the KILL diversion.
9288 Extracted from...
9289 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9290 (AC_CONFIG_LINKS): here.
9291 Adjust.
9292 Don't use the KILL diversion, as it kills spurious output, which
9293 results in failures being hidden.
9294 Use m4_defn where appropriate.
9295 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9296 after the second argument.
9297 Use m4_defn.
9298 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9299 syntax, as it is provided by M4sugar.
9300 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9302 2002-04-03 Andreas Schwab <schwab@suse.de>
9304 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9305 expanded if $# <= 2.
9307 * bin/autoreconf.in (autoreconf): Run automake after rerunning
9308 aclocal.

9312 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
9313 (_AC_COMPILER_EXEEXT_REJECT): New.
9314 Also recognize *.bb and *.bbg as compilation byproducts.
9315 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9316 (_AC_COMPILER_OBJEXT): Use them.
9317 Fixes Debian #138666.
9319 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9321 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9323 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9324 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9325 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9326 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9327 (AC_C_CONST): Same.
9328 (AC_C_INLINE): Same.

9331 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9332 AC_C_CROSS.

9336 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
9337 _AS_MKDIR_P_PREPARE.
9339 2002-03-28 Kevin Ryde <user42@zip.com.au>
9341 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9342 to avoid versions of HP C which don't allow that.
9344 2002-03-27 Paul Eggert <eggert@twinsun.com>
9346 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9347 (AS_SHELL_SANITIZE): Invoke it.
9348 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9350 2002-03-26 Akim Demaille <akim@epita.fr>
9352 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9354 2002-03-26 Akim Demaille <akim@epita.fr>
9356 * doc/autoconf.texi (Introduction): The GNATS base moved.
9358 2002-03-25 Paul Eggert <eggert@twinsun.com>
9360 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9361 as POSIX requires, as it doesn't work with Zsh.
9362 * doc/autoconf.texi (Assignments): Document the problem.
9364 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9366 * doc/autoconf.texi (Limitations of Make): Mention more issue
9367 about VPATH, overriding of macros in sub-makes, and handling of
9368 SHELL.
9370 2002-03-21 Paul Eggert <eggert@twinsun.com>
9372 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9373 problem with here-document buffer boundaries.
9375 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9376 when reinvoking the shell, to work around problems with installers
9377 who put strange things like "cd" commands in their environments.
9379 2002-03-19 Akim Demaille <akim@epita.fr>
9381 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9382 From Aaron Ucko.
9384 2002-03-19 Akim Demaille <akim@epita.fr>
9386 * bin/autoscan.in (scan_file): Specify the location in `&used'
9387 invocations.
9388 From Nicolas Joly.
9390 2002-03-19 Akim Demaille <akim@epita.fr>
9392 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9393 From Nishio Futoshi.
9395 2002-03-19 Akim Demaille <akim@epita.fr>
9397 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9399 2002-03-18 Paul Eggert <eggert@twinsun.com>
9401 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9402 (Limitations of Usual Tools): Add mkdir section.
9404 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9405 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9406 back on AS_DIRNAME to compute prefixes otherwise; this is
9407 roughly what mkinstalldirs does. That way, we need not have
9408 our own filename disassembler. The old disassembler did not
9409 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9411 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9412 Create at_test_all by a series of assignments,
9413 not by a single assignment of a long string. The latter causes ksh
9414 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9415 presumably because of a buffer overrun.
9417 2002-03-14 Paul Eggert <eggert@twinsun.com>
9419 * lib/autotest/general.m4 (at_times_skip):
9420 Renamed from at_times. Now a boolean.
9421 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9422 says 'times: not found'.
9424 2002-03-14 Akim Demaille <akim@epita.fr>
9426 * bin/autoreconf.in (&study_gettextize): New.
9427 (&autoreconf): Handle newest gettextize.
9428 Rerun aclocal if needed.
9429 Suggested by Andreas Schwab.
9431 2002-03-13 Akim Demaille <akim@epita.fr>
9433 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9435 2002-03-13 Akim Demaille <akim@epita.fr>
9437 * doc/autoconf.texi (Header Portability): New.
9438 Add information about stdint.h and inttypes.h from Paul Eggert.
9440 2002-03-13 Akim Demaille <akim@epita.fr>
9442 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9443 -p'.
9444 From Bob Proulx.
9446 2002-03-12 Akim Demaille <akim@epita.fr>
9448 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9449 m4_require.
9451 2002-03-11 Andreas Schwab <schwab@suse.de>
9453 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9454 does not do it if --with-lispdir is given.
9456 2002-03-08 Akim Demaille <akim@epita.fr>
9458 Version 2.53.
9460 2002-03-08 Akim Demaille <akim@epita.fr>
9462 * doc/autoconf.texi (Subdirectories): Clarify that the
9463 subdirectory should exist.
9465 2002-03-08 Akim Demaille <akim@epita.fr>
9467 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9469 2002-03-08 Akim Demaille <akim@epita.fr>
9471 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9472 aliases the actual variables, and modifications of the former
9473 affect the latter.
9475 2002-03-08 Akim Demaille <akim@epita.fr>
9477 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9478 because of C-c: have m4 output in tmp files, then mv them.
9480 2002-03-08 Akim Demaille <akim@epita.fr>
9482 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9483 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9484 * bin/ifnames.in: Copyright update.
9486 2002-03-08 Akim Demaille <akim@epita.fr>
9488 * doc/autoconf.texi (Invoking autom4te): New.
9490 2002-03-05 Akim Demaille <akim@epita.fr>
9492 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9493 Kevin Ryde.
9495 2002-03-05 Akim Demaille <akim@epita.fr>
9497 Version 2.52i.
9499 2002-03-04 Akim Demaille <akim@epita.fr>
9501 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9502 * lib/autoconf/general.m4 (AC_INIT): More informative error
9503 message for LIBOBJ.
9505 2002-03-04 Akim Demaille <akim@epita.fr>
9507 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9508 parallel builds.
9510 2002-03-04 Akim Demaille <akim@epita.fr>
9512 * doc/autoconf.texi (Transforming Names): Equality between target
9513 and host is irrelevant.
9514 (Specifying Names, Canonicalizing): Remove all references to the
9515 backward compatibility hooks. Rather, collect them all into...
9516 (Hosts and Cross-Compilation): this new section.
9517 * doc/install.texi (System Type): Ditto.
9518 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9519 that `--host' implies cross-compilation.
9521 2002-03-04 Akim Demaille <akim@epita.fr>
9523 * doc/autoconf.texi (Evaluation Macros): New.
9524 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9525 useless.
9526 (_m4_foreach): Define the variant with immediate evaluation so
9527 that it contains exactly the items, not an expression which
9528 evaluation is the current item.
9529 (m4_re_string, m4_re_word): Don't over quote them.
9531 2002-03-04 Akim Demaille <akim@epita.fr>
9533 Instead of having stacking `shift's evaluated at the end, let
9534 `foreach' loops immediately evaluate them.
9536 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9537 $*. This is the n-th time I change my mind, but hopefully this is
9538 the last...
9539 (m4_lquote): New.
9540 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9541 efficient.
9542 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9543 it was only a hack for m4_text_wrap.
9544 (m4_car2): Remove, replaced by...
9545 (m4_cdr): New.
9546 (_m4_foreach): Adjust.
9547 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9548 m4_bpatsubst for clarification.
9550 2002-03-04 Akim Demaille <akim@epita.fr>
9552 * doc/autoconf.texi (Changequote is Evil): New.
9554 2002-03-03 Kevin Ryde <user42@zip.com.au>
9556 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
9557 on old systems like SunOS.
9559 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
9561 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9562 lib/autoconf/functions.m4, lib/autoconf/general.m4,
9563 lib/autoconf/headers.m4, lib/autoconf/lang.m4,
9564 lib/autoconf/programs.m4, lib/autoconf/status.m4: Improve spelling
9565 of messages.
9567 2002-02-28 Akim Demaille <akim@epita.fr>
9569 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
9570 message to be sent.
9572 2002-02-28 Kevin Ryde <user42@zip.com.au>
9574 * doc/autoconf.texi (Function Portability): Add va_copy and va_list.
9576 2002-02-25 Akim Demaille <akim@epita.fr>
9578 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9579 From Akinori Musha.
9581 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9583 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9584 translate \r\n to \n.
9586 2002-02-07 Akim Demaille <akim@epita.fr>
9588 Version 2.52h.
9590 2002-02-07 Akim Demaille <akim@epita.fr>
9592 Fix Autoconf PR/209.
9593 Also reported by Frank Denis.
9595 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9597 2002-02-07 Akim Demaille <akim@epita.fr>
9599 Fix Autoconf PR/207:
9600 AC_PREFIX_PROGRAM fails with dashed program names
9602 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9603 variable when looking for the prefix program.
9604 Now it also works for shell variables.
9606 2002-02-07 Akim Demaille <akim@epita.fr>
9608 * doc/autoconf.texi (Limitations of Builtins): More about
9609 case/esac.
9611 2002-02-06 Akim Demaille <akim@epita.fr>
9613 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9614 case/esac, some shells don't support it.
9615 Reported by Zack Weinberg.
9616 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9618 2002-02-06 Akim Demaille <akim@epita.fr>
9620 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9621 sure not to introduce newlines in at_groups.
9622 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9624 2002-02-06 Akim Demaille <akim@epita.fr>
9626 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9627 is not available.
9629 2002-02-05 Paul Eggert <eggert@twinsun.com>
9631 * doc/autoconf.texi (Specific Compiler Characteristics):
9632 Describe HP-UX cc bug workaround more accurately.
9633 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9634 not unsigned long.
9635 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9636 cross-compilers, too. This undoes some of the most recent change
9637 to this file.
9639 2002-02-05 Akim Demaille <akim@epita.fr>
9641 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9642 to make sure they are up to date when `check' is run.
9644 2002-02-05 Akim Demaille <akim@epita.fr>
9646 * doc/autoconf.texi (Making testsuite Scripts): Document
9647 package.m4.
9649 2002-02-05 Akim Demaille <akim@epita.fr>
9651 * lib/freeze.mk: New.
9653 2002-02-05 Akim Demaille <akim@epita.fr>
9655 Implement `autom4te --freeze'.
9657 * bin/autom4te.in (&freeze): New.
9658 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9659 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9661 2002-02-05 Akim Demaille <akim@epita.fr>
9663 * bin/autom4te.in (&parse_args): Implement `frozen files are
9664 optional are the sum of the previous files on the command line'.
9665 Also, pass `--reload-state=' on them, so...
9666 (handle_m4): don't.
9667 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9668 (M4sh): Rely on M4sugar.
9669 (Autotest, M4sh, M4sugar): Use frozen files.
9671 2002-01-31 Akim Demaille <akim@epita.fr>
9673 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9674 * doc/autoconf.texi (Initializing configure): Adjust.
9676 2002-01-30 Akim Demaille <akim@epita.fr>
9678 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9679 alphanumeric to `-' instead of `_'.
9681 2002-01-30 Akim Demaille <akim@epita.fr>
9683 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9684 for plain code, the other for cross-compilation code. The latter
9685 is now run with GCC only.
9686 * doc/autoconf.texi (Compilers and Preprocessors): New.
9688 2002-01-30 Akim Demaille <akim@epita.fr>
9690 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9691 values.
9692 * doc/autoconf.texi (Initializing configure): Explain how to
9693 change AC_INIT default values.
9695 2002-01-29 Akim Demaille <akim@epita.fr>
9697 * tests/torture.at (Configuring subdirectories): Use configure.in,
9698 so that aclocal 1.4 works.
9699 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9701 2002-01-28 Akim Demaille <akim@epita.fr>
9703 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9704 needs an argument.
9706 2002-01-28 Akim Demaille <akim@epita.fr>
9708 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9709 AUTOTEST_PATH *after* it was set.
9710 Don't put `.' in the PATH: the user should be precise and `./' if
9711 needed. In addition, given that the test suite does some `cd', if
9712 `.' is in the path, the `tested programs' sections will report
9713 programs found in the test suite's directory, while during the
9714 tests (performed in their own directory), these programs are no
9715 longer visible. In other words, the results is confusing and
9716 useless.
9717 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9719 2002-01-24 Akim Demaille <akim@epita.fr>
9721 Version 2.52g.
9723 2002-01-24 Akim Demaille <akim@epita.fr>
9725 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
9726 * doc/autoconf.texi: Finally add Akim as an author.
9728 2002-01-24 Akim Demaille <akim@epita.fr>
9730 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9731 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9732 Bourne. Use /bin/sh.
9733 From Andreas Buening.
9735 2002-01-24 Akim Demaille <akim@epita.fr>
9737 * config/config.guess, config/config.sub, config/texinfo.tex:

9745 * config/missing.m4, config/sanity.m4, config/select.m4,
9746 * config/strip.m4: Remove, to ease sync'ing with any version of
9747 Automake.
9749 2002-01-24 Akim Demaille <akim@epita.fr>
9751 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9752 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9753 Reported by Geir Ove Myhr.
9755 2002-01-21 Akim Demaille <akim@epita.fr>
9757 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
9759 2002-01-21 Akim Demaille <akim@epita.fr>
9761 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9762 message on invalid options.
9763 * bin/autom4te.in (parse_args): Don't use
9764 Autoconf::General::getopt with non valid options.

9780 2002-01-06 Akim Demaille <akim@epita.fr>
9782 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9783 package.m4, since is really depends upon configure.ac, not
9784 configure.
9785 * doc/autoconf.texi (testsuite Scripts): Adjust.
9786 * tests/Makefile.am (package.m4): New.
9787 EXTRA_DIST it since its a source.
9789 2002-01-06 Akim Demaille <akim@epita.fr>
9791 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9792 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9793 and PACKAGE_BUGREPORT from here...
9794 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9795 arguments.
9796 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9797 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

9806 2002-01-03 Akim Demaille <akim@epita.fr>
9808 * doc/autoconf.texi (Output): Improved wording regarding use of
9809 AC_OUTPUT.

9812 2001-12-18 Kevin Ryde <user42@zip.com.au>
9814 * doc/autoconf.texi (Function Portability): Add notes on sscanf
9815 sometimes needing writable input.
9817 2001-12-17 Jim Meyering <meyering@lucent.com>
9819 * doc/autoconf.texi (New Macros): Tweak wording.
9821 2001-12-14 Akim Demaille <akim@epita.fr>
9823 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9824 trailing files, don't apply `-rf' to files which might not be
9825 created by configure (core, core.*, and *.core), but just `rm -f'.
9826 Suggested by Jonathan Kamens.
9828 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9830 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

9834 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9836 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

9839 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9840 abs_srcdir, top_srcpath to abs_top_srcdir.
9841 (_AC_OUTPUT_FILES): Adjust.
9842 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
9843 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
9844 * tests/wrappl.in, tests/wrapsh.in: Adjust.
9846 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
9848 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
9849 C/Fortran linking on HP/UX, by extracting the Fortran library
9850 search path from the LPATH line in the $F77 -v output.
9852 2001-12-12 Kevin Ryde <user42@zip.com.au>
9854 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9855 forbidden file descriptors table.
9857 2001-11-26 Akim Demaille <akim@epita.fr>
9859 * bin/autoscan.in (%c_keywords): Build it at top level.
9860 Map to 1 in order to simplify its uses.
9862 2001-11-26 Akim Demaille <akim@epita.fr>
9864 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9865 Remove $filepath, useless.
9866 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9867 variables, they are really part of the tokens.
9868 Split the input line on spaces and then look for tokens.
9869 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9870 because of `lex$U.$(OBJEXT)'.
9871 (&scan_files): Use "@list" instead of join.
9872 * doc/Makefile.am (CLEANFILES): Add *.fns.
9874 2001-11-26 Akim Demaille <akim@epita.fr>
9876 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
9877 Remove, replaced by...
9878 * tests/wrappl.in: Be common for all the Perl executables.
9879 In particular autoscan and autoheader want -I.
9880 * configure.ac: Adjust.
9881 * lib/autoscan/headers: errno.h is portable.
9883 2001-11-26 Akim Demaille <akim@epita.fr>
9885 * bin/autoscan.in (used): New.
9886 Use it.
9888 2001-11-26 Akim Demaille <akim@epita.fr>
9890 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9891 directives.
9892 (&scan_sh_file): Remove a duplicate pattern.
9893 (&check_configure_ac): Use long options.
9894 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9896 2001-11-26 Akim Demaille <akim@epita.fr>
9898 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9899 Before, having a line containing the opening of a multi line
9900 comment made the whole line be ignored.
9902 2001-11-26 Akim Demaille <akim@epita.fr>
9904 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9905 (testsuite Scripts): Be one of its subsection.
9906 (Autotest Logs): New.
9908 2001-11-26 Akim Demaille <akim@epita.fr>
9910 Test groups are now run two directories deeper.
9912 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9913 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9914 at_top_builddir.
9915 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9916 top_srcdir, builddir and top_builddir.
9917 Use `at_*dir' relatively to the directory containing the
9918 suite, use `*dir' when relatively to the current group dir.
9920 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9922 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9923 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9924 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9925 spelling errors.
9927 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9929 * doc/autoconf.texi (Using System Type): Add an example of `case
9930 $host' usage so people quit using `case $target' everywhere.
9932 2001-11-22 Akim Demaille <akim@epita.fr>
9934 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9935 spotted by Jim Meyering.
9937 2001-11-16 Paul Eggert <eggert@twinsun.com>
9939 This patch implements a `long double' suggestion by Oliver Kiddle.
9941 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9942 static, to catch errors if the value isn't known at compile-time
9943 and the compiler supports dynamic arrays. Change its name from
9944 `_array_' to `test_array' to avoid potential name clashes.
9945 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9946 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9947 better than double. Catch a bug in GCC 2.95.2 x86.
9948 * doc/autoconf.texi (C Compiler): Document the above.
9949 * NEWS: Likewise.
9951 2001-11-13 Akim Demaille <akim@epita.fr>
9953 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9954 hand.
9955 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9957 2001-11-13 Akim Demaille <akim@epita.fr>
9959 * lib/autotest/general.m4 (AT_INIT): After having run the test
9960 group, go back to the initial directory, not to at_suite_dir.
9962 2001-11-13 Akim Demaille <akim@epita.fr>
9964 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9965 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9966 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9967 option.
9968 (AT_CHECK_CONFIGURE): Use absolute paths.
9969 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9970 The problem is still the old one: there is no means in M4 (that I
9971 know about) to create a defining macro, because there is no means
9972 to create `$1' etc., therefore, the defining macro ``swallows''
9973 all the arguments meant to the defined macro.
9975 2001-11-13 Akim Demaille <akim@epita.fr>
9977 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9978 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9979 configure.ac.
9980 * tests/aclocal.m4: Remove, as it is no longer used.
9982 2001-11-13 Akim Demaille <akim@epita.fr>
9984 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9985 variable names when referring to a single test group, or to
9986 `suite' when referring to the whole test suite.
9987 `at_last_test' is removed: m4 compute at_format itself.
9988 (at_stdout, at_stder1, at_stderr): New variables.
9989 (AT_CHECK): Use them.
9991 2001-11-13 Akim Demaille <akim@epita.fr>
9993 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9994 in PATH.
9995 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9996 Do it as soon as a test fails, don't wait till the end of the test
9997 suite.
9998 Don't remove $as_me.[0-9]*, since these files no longer exist.
10000 2001-11-13 Akim Demaille <akim@epita.fr>
10002 * tests/tools.at: Use absolute paths, since we are no longer run
10003 in place.
10005 2001-11-13 Akim Demaille <akim@epita.fr>
10007 Now that tests are running in their own private dir, there is no
10008 need to list the files to remove at the end of tests groups.
10010 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10011 (AT_data_files, at_data_files): Remove.
10012 (AT_CLEANUP, AT_DATA): Simplify.
10013 (AT_INIT): Adjust.
10014 Remove the group dir if !debug && !failed.
10015 * tests/atspecific.m4: Adjust.
10017 2001-11-13 Akim Demaille <akim@epita.fr>
10019 Start a new layout for Autotest: `testsuite' creates
10020 `testsuite.dir' in which the at-check-line etc. files are to be
10021 found, and `testsuite.dir/003' where the test group 3 is run.
10023 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10024 at_check_line_file, at_format, at_test_normalized, at_group_dir
10025 are new variables.
10026 Create the directories.
10027 Use absolute paths for at- files.
10028 (AT_CHECK): Adjust.
10030 2001-11-11 Michael Matz <matz@kde.org>
10032 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10033 (m4_car2): New.
10034 (m4_car): Properly quote arguments.
10036 2001-11-13 Akim Demaille <akim@epita.fr>
10038 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10039 with stricter rules on LIBOBJS.
10041 2001-11-12 Paul Eggert <eggert@twinsun.com>
10043 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10044 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10045 __PROTOTYPES too.
10047 2001-11-12 Akim Demaille <akim@epita.fr>
10049 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10051 2001-11-12 Akim Demaille <akim@epita.fr>
10053 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10054 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10055 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10056 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10057 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10058 specify to what the macro should be defined (typically to 1).
10060 2001-11-12 Akim Demaille <akim@epita.fr>
10062 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10063 From Jim Meyering.
10065 2001-11-12 Akim Demaille <akim@epita.fr>
10067 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10068 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10069 definition used by Automake where LEX is +/- "${missing} lex" and
10070 `missing' itself contains variables.
10072 2001-11-12 Akim Demaille <akim@epita.fr>
10074 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10075 Now that M4sh pushes BODY, the comments were output at the end of
10076 the test suites.
10078 2001-11-08 Akim Demaille <akim@epita.fr>
10080 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10081 that we can trace macros from aclocal.m4.
10082 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10083 obsoleted, and redirect to the former anyway.
10084 Reported by Ralf Corsepius.
10086 2001-11-08 Akim Demaille <akim@epita.fr>
10088 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10089 processed only if present.
10090 * tests/torture.at (Configuring subdirectories): Use autoreconf
10091 instead of successive calls to autoconf.
10092 Add a nonexistent subdirectory to exercise the patch above.
10093 Reported by Ralf Corsepius.
10095 2001-11-08 Kevin Ryde <user42@zip.com.au>
10097 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10098 doesn't accept .S files.
10100 2001-11-07 Akim Demaille <akim@epita.fr>
10102 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10103 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10104 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10105 * bin/autom4te.in (warn_forbidden): New.
10106 (handle_output): Use it.
10107 Read m4_pattern_forbid with messages.
10109 2001-11-05 Akim Demaille <akim@epita.fr>
10111 * bin/autom4te.in (--normalize): Remove.
10112 * lib/autom4te.in: Adjust.
10114 2001-11-05 Akim Demaille <akim@epita.fr>
10116 * tests/Makefile.am (testsuite): Rename this target as...
10117 ($(TESTSUITE)): this.
10118 From Nicolas Joly.
10120 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10122 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10123 the --prefix option, also remove it's argument.
10125 2001-11-05 Akim Demaille <akim@epita.fr>
10127 * doc/autoconf.texi (testsuite Invocation): Update.
10128 (Writing testsuite.at): Update.
10130 2001-11-03 Akim Demaille <akim@epita.fr>
10132 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10134 2001-11-03 Akim Demaille <akim@epita.fr>
10136 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10137 (&file_name_is_absolute): New, wrappers around routines from
10138 File::Spec.
10139 Use and export them.
10140 (&find_configure_ac): Optionally take a directory where to look at.
10141 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10142 the arguments.
10143 Default @ARGV to `.', not find_configure_ac.
10144 (&autoreconf): Argument is a directory.
10145 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10146 * doc/autoconf.texi (autoreconf Invocation): Update.
10148 2001-11-03 Akim Demaille <akim@epita.fr>
10150 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10151 (@export_forward_subs): New.
10152 Add basename, dirname, and fileparse.
10153 (@EXPORT): Adjust.
10154 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10155 Don't look for aclocal flags if we already know aclocal is not
10156 used.
10157 Move aclocal.m4t only if it exists.
10158 Reported by Ezra Peisach.
10160 2001-11-03 Akim Demaille <akim@epita.fr>
10162 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10163 passed on command line, defaulting to ./configure.ac if present.
10164 (&maybe_autoreconf, File::Find): Remove, unused.
10165 (&autoreconf): If autoconf is not used, don't try to trace.
10167 2001-11-02 Akim Demaille <akim@epita.fr>
10169 * configure.ac: Bump to 2.52g.
10171 2001-11-02 Akim Demaille <akim@epita.fr>
10173 Version 2.52f.
10175 2001-11-02 Akim Demaille <akim@epita.fr>
10177 * config/config.guess, config/config.sub, doc/standards.texi:
10178 * config/lispdir.m4: Update from masters.
10179 * configure.ac: Bump to 2.52f.
10181 2001-11-02 Akim Demaille <akim@epita.fr>
10183 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10184 Don't run aclocal when aclocal.m4 is not from aclocal.
10185 From Ezra Peisach.
10186 Don't run libtoolize and gettextize if --install is not given.
10188 2001-11-01 Paul Eggert <eggert@twinsun.com>
10190 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10191 be invoked before _AS_LINENO_PREPARE.
10192 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10193 than character ranges.
10195 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10196 invoking AS_BASENAME. Set the locale variables to 'C' if
10197 possible, as POSIX requires this to get the traditional
10198 behavior.
10199 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10201 2001-10-31 Paul Eggert <eggert@twinsun.com>
10203 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10204 with {}, as that triggers a bug in Bash 2.05.
10206 (_AS_LINENO_PREPARE): Use Sed rather than
10207 Awk. Fix the sed prepass to work even if there are multiple
10208 instances of $LINENO on the same line. Do not substitute for
10209 other variables like $LINENOT. Do not check file dates; such a
10210 check is unreliable on sufficiently fast machines, and removing
10211 the check makes the code simpler and more reliable. Check for
10212 output and chmod failures.
10214 * doc/autoconf.texi (Special Shell Variables): Document
10215 the above.
10217 2001-10-31 Akim Demaille <akim@epita.fr>
10219 * tests/Makefile.am (atconfig): Remove this target, Automake

10222 2001-10-31 Akim Demaille <akim@epita.fr>
10224 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not

10227 * configure.ac: Adjust.
10229 2001-10-26 Paul Eggert <eggert@twinsun.com>
10231 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10232 lib/Autom4te/Struct.pm:
10233 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10234 with 5.005_02.
10236 * doc/autoconf.texi (Special Shell Variables): Document some
10237 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10239 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10240 (_AS_LINENO_PREPARE): Use it instead of shell eval, since

10260 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10261 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10262 POSIX decided to standardize on the int flavor of strerror_r.
10263 Always do char* test, as there's no reason not to.
10264 Assign to a char* var, to catch strerror_r that returns int*.
10266 * doc/autoconf.texi (Particular Functions):
10267 Document the above changes. Also, document the fact that
10268 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

10292 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10293 Remove, dead.
10294 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10295 `intl' is already present, as it refuses unless --force.
10296 (&parse_args): Use -I, --include instead of the old Autoconf
10297 options.

10332 (AS_BASENAME_EXPR): New macro.
10333 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10334 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10335 and fall back on 'sed' only if the other two fail. This makes
10336 AS_BASENAME act more like AS_DIRNAME.
10337 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10338 contains white space.
10339 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

10341 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10342 Allow "dirname //FOO" to return either / or //, as POSIX allows
10343 either behavior.

10393 bother with $force since...
10394 * lib/Autom4te/General.pm: does.
10396 2001-10-08 Akim Demaille <akim@epita.fr>
10398 * bin/autoreconf.in: Rewrite in Perl.

10485 ourselves with CONFIG_SHELL.
10487 2001-10-05 Paul Eggert <eggert@twinsun.com>
10489 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

10569 the type exists.

10572 and invoke a new argument $4 if either is discovered.
10573 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
10574 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

10608 * tests/fortran.at (GNU Fortran 77): there.
10609 * doc/autoconf.texi (autoconf Invocation): Fix the example:

10616 Raja R Harinath:

10619 enough.

10714 * lib/autoconf/autotest.m4: Create `package.m4'.
10715 * tests/Makefile.am (package.m4): Remove.
10717 2001-09-22 Akim Demaille <akim@epita.fr>
10719 Rely on `$LINENO' when possible instead of `__oline__'.
10721 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
10722 `$LINENO' support replacement when not supported.
10723 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
10724 them explicitly to be sure they are not output before this section
10725 (via m4_require). Cosmetic only.
10726 * lib/autoconf/c.m4, lib/autoconf/general.m4,
10727 * lib/autoconf/programs.m4: Replace all the occurrences of
10728 `__oline__' with `$LINENO'.
10729 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
10731 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
10733 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
10734 character (u: -> ue) in a code comment.
10735 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
10736 it works.
10738 2001-09-21 Akim Demaille <akim@epita.fr>
10740 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
10741 Suggested by Jim Meyering.
10743 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10745 * lib/autoconf/programs.m4: Use extensions listed in
10746 $ac_executable_extensions when looking for programs.
10748 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10750 * lib/autoconf/general.m4: Fix a small Englisho.

10752 setting up ac_dir_suffix and ac_top_builddir.
10753 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
10755 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

10758 PATH_SEPARATOR.
10759 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

10761 be used instead of ':'.
10762 * lib/autotest/general.m4: Replace occurrences of ':' in
10763 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10765 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10767 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10768 arguments. Fixed a typo.
10770 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10772 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
10773 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
10775 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10777 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
10778 * bin/autoupdate.in: Ditto.
10779 * bin/autoheader.in: Reworded a few comments.

10784 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10786 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10787 already have $file). Set output files to binary mode (helps avoid
10788 CR issues on DOSish systems).
10790 2001-09-19 Akim Demaille <akim@epita.fr>
10792 * lib/autotest/general.m4: Englishoes.
10793 From Tim Van Holder and Alexey Mahotkin.
10795 2001-09-18 Paul Eggert <eggert@twinsun.com>
10797 * doc/autoconf.texi (Common Shell Constructs): New node,
10798 documenting AS_DIRNAME.
10799 (Limitations of Usual Tools): Refer to it when discussing dirname.
10800 Also, update discussion of POSIX standard to reflect latest draft.
10802 * lib/autoconf/c.m4:
10803 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10805 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10806 Do not pass a first argument with leading '-'
10807 to expr, by parenthesizing initial integers that might be negative.
10809 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10810 now merely checks whether it is an error to pass an argument
10811 to getpgrp.
10813 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10814 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10815 whether it is a (compile-time) error to pass an argument to
10816 getpgrp. This simpler test supports the revised documentation,
10817 and is all that AC_FUNC_GETPGRP's users really need.
10819 2001-09-18 Akim Demaille <akim@epita.fr>
10821 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10823 2001-09-18 Akim Demaille <akim@epita.fr>

10831 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10832 correctly.
10833 Add test for AS_BASENAME.
10834 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10835 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10836 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10837 * tests/base.at: Fixed the expected responses. The old ones were
10838 one line out...
10839 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10840 the documentation claims it should (and how it behaved in 2.13).
10842 2001-09-18 Akim Demaille <akim@epita.fr>
10844 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10845 the AC_CONFIG_COMMANDS invocation.
10846 This also solves the name clash problems.
10847 Don't set the package's ID.
10848 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10849 No longer to be shipped.
10850 (version.in): Remove.
10851 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10852 * lib/autoconf/status.m4: Adjust.
10853 Use `m4_PACKAGE_STRING'.
10854 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10855 the only optional argument is the name of the test suite.
10856 Expect `package.m4' to define the package signature.
10857 * lib/autom4te.in (Autotest): Add `package.m4?'.
10858 * tests/Makefile.am (package.m4): New.
10859 * tests/suite.at: ifnames is a victim.
10861 2001-09-18 Akim Demaille <akim@epita.fr>
10863 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10864 AC_LIBSOURCE, AC_CONFIG_FILES.
10865 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10866 program version string doesn't match the package's.
10867 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10868 after `(cached)'.
10870 2001-09-17 Paul Eggert <eggert@twinsun.com>
10872 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10873 Allow expression to return any value that can fit into unsigned long
10874 (not int, as before). Check for output errors.
10876 2001-09-17 Bruno Haible <haible@ilog.fr>
10878 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10879 Always include <stdio.h> and <stdlib.h>. Evaluate
10880 the expression in an extra function before these includes. Call
10881 fprintf "%d" only after ensuring the argument is of type 'int'.
10882 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10884 2001-09-17 Paul Eggert <eggert@twinsun.com>
10886 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10887 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10888 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10889 when they don't exist.
10891 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10892 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10893 need it.
10895 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10896 version with the version used by fileutils 4.1, except use
10897 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10898 we don't need it.
10900 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10902 2001-09-13 Akim Demaille <akim@epita.fr>
10904 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10905 _first_.
10906 Reported by Gerrit P. Haase.
10908 2001-09-13 Akim Demaille <akim@epita.fr>
10910 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

10930 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
10931 AT_tests_all for consistency.

10933 (AT_VICTIMS): Similar to AT_KEYWORDS.
10934 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
10936 2001-09-13 Akim Demaille <akim@epita.fr>
10938 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
10940 2001-09-13 Akim Demaille <akim@epita.fr>
10942 * lib/autotest/general.m4 (AT_INIT): Create and remove
10943 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10944 test suites can cohabit.
10946 2001-09-13 Akim Demaille <akim@epita.fr>
10948 * tests/mktests.sh: Don't output banners for empty test files.
10950 2001-09-13 Akim Demaille <akim@epita.fr>
10952 Test suites can be run independently of configure.
10954 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
10955 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

10967 (Syntax of the shell scripts): Don't check ifnames.
10968 (AT_CHECK_PERL_SYNTAX): New.

10994 (m4_list_append): Remove.
10996 Spread a few keywords in the Autoconf test suite.
10998 2001-09-10 Akim Demaille <akim@epita.fr>
11000 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

11016 2001-09-07 Akim Demaille <akim@epita.fr>
11018 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
11019 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
11020 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
11021 related variables into `at_package_*'.

11033 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
11034 in addition, it introduces useless differences in logs.
11035 (AT_INIT): Let atconfig and atlocal be both optional.
11036 Adjust PATH computation.

11046 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'
11047 to avoid GCC warnings.
11048 From Uwe Seimet.
11050 2001-09-05 Akim Demaille <akim@epita.fr>
11052 * bin/autom4te.in: --language is -l, not -s.
11054 2001-09-05 Akim Demaille <akim@epita.fr>
11056 Be ready to handle filenames as stupid as `dnl.at', for if even
11057 the maintainer is dumb enough to do that...
11059 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11060 excellence in M4 quotation: consider `__file__' is active.

11093 New, extracted from main.
11094 Use IO::File wherever possible.

11097 Don't invoke `_au_disable', since ac was not loaded, but just

11118 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
11119 (Making testsuite Scripts): Update.
11121 2001-08-31 Akim Demaille <akim@epita.fr>
11123 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11125 2001-08-31 Akim Demaille <akim@epita.fr>
11127 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11128 (testsuite Scripts): There is no such thing as `atconfig.in'.
11129 And actually one diagram is missing: test suite runtime.
11131 2001-08-31 Akim Demaille <akim@epita.fr>
11133 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11134 inverse order.
11136 2001-08-31 Akim Demaille <akim@epita.fr>
11138 * bin/autoupdate.in (@include): `installcheck' revealed the path
11139 to m4sugar was lacking!
11141 2001-08-31 Akim Demaille <akim@epita.fr>
11143 * man/Makefile.am (.x.1): We really have to pass
11144 autom4te_perllibdir.
11146 2001-08-31 Akim Demaille <akim@epita.fr>
11148 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11149 debug scripts, in particular passing explicitly listed tests to
11150 run is stupid.
11152 2001-08-31 Akim Demaille <akim@epita.fr>
11154 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11155 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11156 Use directly autom4te, not autoconf.
11157 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
11159 2001-08-31 Akim Demaille <akim@epita.fr>
11161 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
11162 * bin/autoheader.in (%symbol): Strip arguments of macros.
11164 2001-08-31 Akim Demaille <akim@epita.fr>
11166 * doc/autoconf.texi: Catch up -I, --include changes.
11168 2001-08-31 Akim Demaille <akim@epita.fr>
11170 * bin/autom4te.in (&parse_args): Die on unknown languages.
11171 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
11172 need for autoconf.
11173 Promote --include over --macrodir and other obsolete options.
11175 2001-08-31 Akim Demaille <akim@epita.fr>
11177 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
11178 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
11179 * bin/autom4te.in ($autoconf): Pass --force.
11180 `print $out' doesn't print `$_' but `$out'.
11181 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11182 (autoheader): Pass --force since the test suite goes too fast for
11183 the time stamps.
11184 Adjust to the new autoheader messages.
11186 2001-08-31 Akim Demaille <akim@epita.fr>
11188 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11189 Check the completeness of the #template.
11190 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
11191 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
11192 invocation.
11194 2001-08-31 Akim Demaille <akim@epita.fr>
11196 * lib/Autom4te/General.pm (&find_file, &update_file): New.
11197 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11198 Drop AC_MACRODIR dead for real.
11199 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11200 `autoheader: `config.hin' is created'.
11201 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11203 2001-08-31 Akim Demaille <akim@epita.fr>
11205 * bin/autoheader.in: Rewrite in Perl.
11206 * tests/autoheader: Adjust.
11208 2001-08-31 Akim Demaille <akim@epita.fr>
11210 * bin/autoconf.in (--include, -I): New option.
11211 Map --localdir, --autoconf-dir onto it.
11212 Forward autom4te's options instead of interpreting them.
11213 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11214 There is no such envvar since the inception of autom4te.cfg.
11215 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11216 * bin/autoupdate.in: Adjust, and perform more control.
11217 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11218 * tests/autoconf: Dittowise.
11220 2001-08-31 Akim Demaille <akim@epita.fr>
11222 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11223 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11224 optionally `FILE'.
11225 Use -e, not -f, since /dev/null for instance is OK.
11226 (&parse_args): Adjust.
11227 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11229 2001-08-31 Akim Demaille <akim@epita.fr>
11231 * configure.ac: Also find tested executables in bin.
11232 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11233 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11234 installed peer executables, only PATH is allowed to resolve it.
11235 Pass `autoconf_dir' via options, not via invisible envvars.
11236 * lib/Autom4te/General.pm (&find_peer): Remove.
11237 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11238 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11239 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11240 find the executables for it.
11241 * tests/Makefile.am: Major cleanup. Too lazy to document...
11242 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11243 We only need PERL.
11244 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11245 indeed related to running the test suite, while passing
11246 --autoconf-dir and others is related to running non installed
11247 Autoconf executables. So don't do that, leave it to...
11248 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11249 * tests/autoscan: New.
11250 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11251 refer to library files: rely on --language.
11253 2001-08-29 Akim Demaille <akim@epita.fr>
11255 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11256 s/--set/--language/.
11258 2001-08-29 Akim Demaille <akim@epita.fr>
11260 * doc/autoconf.texi: Strip the @nodes.
11261 Suggested by Paul Eggert.
11262 (Initializing configure): Typo.
11264 2001-08-29 Akim Demaille <akim@epita.fr>
11266 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11267 Suggested by Paul Eggert.
11269 2001-08-29 Akim Demaille <akim@epita.fr>
11271 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11272 download in a tmp dir.
11274 2001-08-29 Akim Demaille <akim@epita.fr>
11276 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11277 case insensitive OSes out there :(
11278 From Tim Van Holder.
11280 2001-08-29 Akim Demaille <akim@epita.fr>
11282 * lib/autom4te.in: New.
11283 * lib/Makefile.am (edit, autom4te.cfg): New.
11284 * bin/autom4te.in (BEGIN): Simplify.
11285 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
11286 (&load_configuration): New. Use it.
11287 (&parse_args): Support --mode, --set, and --melt.
11288 * bin/autoconf.in: Simplify and adjust.
11289 * tests/Makefile.am (AUTOMAKE): Use --set.
11290 * tests/atlocal.in: Adjust.
11291 * BUGS: distcheck and check are weak.
11293 2001-08-29 Akim Demaille <akim@epita.fr>
11295 * lib/autotest/general.m4: Use
11296 foo=`(command) 2>/dev/null`
11297 not
11298 foo=`command` 2>/dev/null
11299 (at-devnull): Rename as...
11300 (AT-devnull): this.
11301 (--clean): Remove AT-* files too.
11302 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11303 Reported by Nicolas Joly.
11305 2001-08-28 Akim Demaille <akim@epita.fr>
11307 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

11309 Reported by Nicolas Joly.
11311 2001-08-28 Kevin Ryde <user42@zip.com.au>
11313 * doc/autoconf.texi (Function Portability): Mention C right shifts.
11315 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
11317 * lib/autotest/general.m4: Reword some messages.
11318 (AT_INIT): Check for the `times' builtin before using it.
11319 Support test ranges as arguments to the testsuite.
11320 Have -e imply -d as the help text suggested.
11322 2001-08-27 Akim Demaille <akim@epita.fr>
11324 * Makefile.maint: Formatting changes.
11325 (do-po-update, po-update, cvs-update, update): New targets.
11326 (AMTAR): Remove.
11328 2001-08-27 Akim Demaille <akim@epita.fr>
11330 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

11337 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11338 Support `VAR=VAL' as arguments.
11339 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
11340 may be set via the command line.
11342 2001-08-27 Akim Demaille <akim@epita.fr>
11344 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
11345 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
11346 first the build dirs, then the src dirs.

11349 2001-08-27 Akim Demaille <akim@epita.fr>
11351 * lib/autotest/general.m4 (AT_INIT): Output the definition of
11352 at_data_files earlier.
11353 (--clean, -c): New option.
11354 * tests/Makefile.am: Use this option.
11356 2001-08-27 Akim Demaille <akim@epita.fr>
11358 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11359 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11360 readable.
11361 Adjust callers.
11362 * doc/autoconf.texi (Configuration Actions): Document the vars
11363 available in commands.
11364 Emphasize the risks of collisions in init-cmds.

11368 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
11369 (Initializing configure): this new node.
11371 2001-08-27 Akim Demaille <akim@epita.fr>
11373 * Makefile.am (EXTRA_DIST): INSTALL.txt is a dead hack.

11384 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
11385 to...
11386 * lib/autoconf/autoheader.m4: this new file.
11387 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)
11388 (_AH_VERBATIM_OLD, AH_TEMPLATE, _AH_TEMPLATE_OLD, AH_TOP, AH_BOTTOM):
11389 Move to...

11392 2001-08-27 Akim Demaille <akim@epita.fr>
11394 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
11395 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
11396 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11397 -> ac_dir).
11398 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11399 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11401 2001-08-27 Akim Demaille <akim@epita.fr>
11403 * lib/autoconf/autoconf.m4 (AC_CONFIG_COMMANDS)

11426 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
11427 (AMTAR): Help automake define it.
11428 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
11429 needed, 1.5 can have a macro and a target with the same name.
11430 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
11431 * m4/strip.m4: New.

11444 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
11445 Adjust callers.
11446 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11447 the name of the directory they're in, instead of the filename,
11448 since version.m4 is now in m4sugar, but m4_acversion must not be
11449 classified as an Autoconf macro.
11450 ($input_m4): Don't qualify the path to m4sugar.
11451 Rather, pass autoconf_dir to m4.
11452 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
11453 * tests/suite.at: Require 2.52c.
11455 2001-08-27 Akim Demaille <akim@epita.fr>

11467 of config.log on traps.
11468 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
11469 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
11470 for config.status'.
11471 Open the log as soon as possible.
11472 Use the same log introduction as configure's.
11474 2001-08-22 Paul Eggert <eggert@twinsun.com>
11476 * doc/autoconf.texi (Indices): New node.
11477 Move indices out of the top level menu and into this submenu.
11479 2001-08-22 Akim Demaille <akim@epita.fr>
11481 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11482 AC_TRY_COMMAND.
11483 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
11485 2001-08-22 Akim Demaille <akim@epita.fr>
11487 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

11524 * configure.ac (AT_CONFIG): Fix the path.
11525 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
11526 can be used.
11528 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
11530 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
11531 program with AC_LANG_PROGRAM before feeding it to
11532 AC_COMPILE_IFELSE. Cleanup grep usage.
11534 2001-08-20 Akim Demaille <akim@epita.fr>
11536 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11537 * NEWS, README, README-alpha, TODO, tests/README: This package is
11538 `Autoconf', not `autoconf' (the executable).
11540 2001-08-20 Akim Demaille <akim@epita.fr>
11542 Info readers seem to need `Index' in the index node title :(
11544 * doc/autoconf.texi: Reverse the 2001-08-15 change which
11545 simplified index node names.
11547 2001-08-20 Akim Demaille <akim@epita.fr>
11549 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
11550 arguments are not literals.

11589 2001-08-20 Akim Demaille <akim@epita.fr>
11591 Huh!?!?! There are still some user EOF tags used, which prevents
11592 their use in AC_CONFIG_COMMANDS for instance...
11594 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11595 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

11658 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
11659 `$0.log' as for projects where testsuite is in src, we'd have

11676 * doc/autoconf.texi: Work around Texinfo buglets.
11677 (Transformation Rules): One example is enough, users are expected
11678 to have their brains on. And BTW, use DESTDIR.
11679 (dvar): New macro. Use it.
11681 2001-08-17 Akim Demaille <akim@epita.fr>
11683 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

11730 (alpha): Don't depend upon local-check, since...
11731 (cvs-dist): depends upon it.
11733 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
11735 * tests/Makefile.am: Use a clean-local rule to remove
11736 autom4te.cache (it's a directory, not a file.
11737 * Makefile.am: Ditto (but maintainer-clean-local).
11739 2001-08-15 Akim Demaille <akim@epita.fr>
11741 * bin/autom4te.in (@m4_warning): New.
11742 (&handle_m4): Use it.
11743 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11744 warnings are issued at each run.
11745 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11746 is in the src tree.
11748 2001-08-15 Akim Demaille <akim@epita.fr>
11750 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
11751 don't waste time running `autoupdate --version' works.
11752 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11754 2001-08-13 Akim Demaille <akim@epita.fr>
11756 * doc/autoconf.texi (ma): Rename this index as...

11809 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
11811 * tests/semantics.at (AC_C_BIGENDIAN): New test.
11813 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11815 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11816 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11817 * doc/autoconf.texi (C Compiler Characteristics): Update
11818 documentation for AC_C_BIGENDIAN.
11820 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11822 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11823 magic values from an object file when cross-compiling.
11824 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11826 2001-08-10 Akim Demaille <akim@epita.fr>
11828 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11829 effects.
11830 Suggested by Russ Allbery.
11832 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11834 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11835 current $prefix to the sub-configures.
11837 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11839 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11840 extension (needed on BeOS). Reported by Guido van Rossum.
11842 2001-08-09 Akim Demaille <akim@epita.fr>
11844 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11846 2001-08-07 Akim Demaille <akim@epita.fr>
11848 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11849 removed.
11850 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11851 No need to remove the files before and after the each test, before
11852 each test and at the end of the suite is enough.
11853 Display only the children `times', not the shell's.
11854 If the test failed or was skipped, at-times is not available.
11856 2001-08-07 Akim Demaille <akim@epita.fr>
11858 Always produce testsuite.log, including when there are no
11859 failures. This helps getting information on skipped tests, and
11860 duration of the tests. Err, implement the latter btw.
11862 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11863 Dump information on the first run of each test.
11864 (AT_CLEANUP): Create `at-times' containing the duration of the
11865 test group.
11867 2001-08-07 Akim Demaille <akim@epita.fr>
11869 The use of `dumpstat' revealed that `len' was used although it
11870 should not. m4_text_wrap was using it, but in the Autoconf world
11871 where it is legal. Hence (i) test M4sh in its own world, not
11872 Autoconf's, and (ii), ahem, fix the bug :)
11874 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11875 does not like `' instead of [].
11876 (AT_INIT): Forbid `^_?AT_'.
11877 And don't output such tokens.
11878 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11879 `script.as', and `autom4te.cache'.
11880 Remove `empty' and `macro' which are no longer used.
11881 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11882 * tests/m4sugar.at: Use it.
11883 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11885 2001-08-07 Akim Demaille <akim@epita.fr>
11887 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11889 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11891 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11893 2001-08-04 Akim Demaille <akim@epita.fr>
11895 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11896 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11897 AC_TRY_LINK.
11898 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11899 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11900 (AC_F77_MAIN): Likewise.
11902 2001-08-04 Akim Demaille <akim@epita.fr>
11904 Don't rely on M4sugar outputting the patterns in files, since we
11905 might process the output _without_ running m4, hence without these
11906 files.
11908 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11909 * bin/autom4te.in (@Request::includes): Remove, unused.
11910 (@Request::source): Rename as...
11911 (@Request::input): this.
11912 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11913 (&handle_output): Fetch the patterns from the traces.
11914 `$forbidden' and `$allowed' are constant: use m//o.
11915 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11916 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11918 2001-08-04 Akim Demaille <akim@epita.fr>
11920 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11921 autoconf', i.e., in addition to caching traces, cache the output.
11923 * bin/autom4te.in (Request::cache): Rename as...
11924 (Request::id): this.
11925 ($cache, $icache, $tcache, $ocache): New.
11926 (&handle_m4): Save M4 output in the cache instead of $tmp.
11927 (&handle_output): Adjust.
11928 (&up_to_date_p): Check that the output cache is up to date too.
11929 (top level): Run `&handle_m4' iff force or the cache is invalid.
11930 Run `&handle_output' if the output cache is more recent.
11932 2001-08-04 Akim Demaille <akim@epita.fr>
11934 * bin/autom4te.in ($force): New.
11935 (&parse_args, &print_usage): -f, --force is a new option.
11936 (&handle_output): CPP directives might have spaces after `#'.
11937 (&parse_args): The first file only can be frozen.
11939 2001-08-04 Akim Demaille <akim@epita.fr>
11941 Don't let autom4te compute the `include' traces several times:
11942 first check that the trace cache file is up to date, and then
11943 compare its timestamp with that of the output.
11945 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11946 the preamble. Don't require 5.005 as Autom4te::General does it,
11947 and better yet (use `use', not `require'!).
11948 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11949 Class::Struct as Autom4te::Struct.
11950 * lib/Autom4te/General.pm (File::stat): Use it.
11951 (&mtime): New, export it.
11952 * bin/autom4te.in: Use it.
11953 Declare `$req' is invalid if it is outdated.
11954 Don't declare it valid before saving it if something went wrong.
11956 2001-08-04 Akim Demaille <akim@epita.fr>
11958 Autom4te shall not encode Autoconf data, and preselecting traces
11959 must be proposed to the users.
11961 * bin/autom4te.in (@required_trace): Remove.
11962 (@preselect): New.
11963 (&parse_args, &print_usage): -p, --preselect is a new option.
11964 (&up_to_date_p): Adjust.
11965 * bin/autoconf.in: Preselect some Autoconf macros.
11967 2001-08-04 Akim Demaille <akim@epita.fr>
11969 * tests/tools.at (autoconf --trace: user macros): Check traces on
11970 macros invoked without arguments, and macros invoked with multiple
11971 lines arguments.
11973 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11975 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11976 arguments.
11978 2001-08-03 Akim Demaille <akim@epita.fr>
11980 * bin/autoconf.in ($@): Work around the usual sh bug.
11981 From Nicolas Joly.
11983 2001-08-03 Akim Demaille <akim@epita.fr>
11985 Clean up the handling of the M4 builtins tracing exception.
11987 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11988 trace requests.

11990 (@m4_builtin): this.
11991 (%m4_builtin_alternate_name): New.
11992 (&parse_args): Complete the trace requests with alternate names.
11993 (&handle_traces): Hence no longer do it here.
11994 (&trace_requests): Remove, unused.
11996 2001-08-03 Akim Demaille <akim@epita.fr>
11998 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11999 m4_if, and m4_wrap.
12001 2001-08-03 Akim Demaille <akim@epita.fr>
12003 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
12004 (m4_divert_pop): Dump the whole diversion stack when a diversion
12005 mismatch happens.
12006 * bin/autom4te.in (&handle_output): Remember of the first
12007 occurrence of a possibly undefined macro, not the last.
12008 Complain about the possibly undefined macros in the same order as
12009 the appear in the output.
12010 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
12011 * tests/tools.at (autoconf: forbidden tokens, basic)

12253 The runtime test for AC_FUNC_GETPGRP fails when prototypes are

12430 compiler, not the preprocessor.
12431 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use
12432 dedicated code to check for inttypes.h, as AC_CHECK_HEADERS does
12433 the right thing.
12434 * Makefile.am (.m4.m4f): Emphasize M4 error messages and fail
12435 earlier if there are.
12437 2001-07-03 Akim Demaille <akim@epita.fr>
12439 * autoscan.in ($initfile): Remove.
12440 (&find_file): Rename as...

12466 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
12467 dummy alternate main is required even if the user provides her own
12468 'main'.
12469 (AC_F77_MAIN): New macro to detect whether it is possible to
12470 provide an alternate 'main' function name, using the 'main' from
12471 the Fortran libraries.
12472 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
12473 cross-language link tests can be performed successfully.
12474 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
