648 2005-10-24 Stepan Kasal <kasal@ucw.cz>
650 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
651 conftest.o, to see whether the compiler really obeys; rm the object
652 file before and after the test and register it with ac_clean_files.

676 AC_LANG_PROGRAM, fixing a typo. Don't give details about
677 the inner workings of AC_LANG_FUNC_LINK_TRY.
678 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
679 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
680 by the function rather than ignoring it.
681 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
682 comparing its address. Intel's interprocedural optimization was
683 outsmarting the old heuristic. Problem reported by
686 2005-10-19 Stepan Kasal <kasal@ucw.cz>
688 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
690 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
692 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
693 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
695 2005-10-04 Stepan Kasal <kasal@ucw.cz>
697 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
698 before removing it (chmod -R u+rwx); there are three instances of this.
700 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
701 Stepan Kasal <kasal@ucw.cz>
703 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
704 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
705 make its content writable before removing it. Remove an errorneous
706 comment from the end, where the logs of the failed tests are copied
707 to the main log file.
709 2005-09-27 Stepan Kasal <kasal@ucw.cz>
711 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
712 in case the computer is too quick. Double quote the configure.ac
715 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
716 problems if the testsuite were running too fast.
718 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
720 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
721 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
722 (which belong to Xt, not X itself). See Debian bug 327655.
723 * NEWS: Mention this.
725 2005-09-07 Stepan Kasal <kasal@ucw.cz>
727 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
729 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
731 * config/move-if-change: Don't output "$2 is unchanged";
732 suggested by Ben Elliston. Handle weird characters correctly.
734 2005-09-06 Stepan Kasal <kasal@ucw.cz>
736 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
737 calls, so that the final expansion of this macro is shorter.
738 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
739 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
740 the cleanup there. Use AS_VAR_* macros, to be more general.
741 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
743 * lib/autoconf/general.m4: Use AS_IF where appropriate.
745 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
747 2005-09-01 Stepan Kasal <kasal@ucw.cz>
749 * doc/autoconf.texi (Configuration Headers): Add an index entry
752 2005-08-26 Pavel Roskin <proski@gnu.org>
754 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
755 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
758 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
760 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
761 The previous patch didn't work, so try a better one.
763 2005-08-26 Stepan Kasal <kasal@ucw.cz>
765 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
766 in the example. Reported by Bruno Haible.
767 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
768 "if $undefined_var;" succeeds with my shell.
770 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
771 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
772 but change the m4_divert_text to m4_divert_once.
774 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
776 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
777 Work around bug in Solaris /usr/xpg4/bin/awk.
778 The bug is present in at least Solaris 8 through 10.
780 2005-08-24 Stepan Kasal <kasal@ucw.cz>
782 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
783 some evil values and relying on the fact that $* concatenates the
784 parameters by the first character from IFS.
786 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
787 Stepan Kasal <kasal@ucw.cz>
789 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
790 first header appears, define AH_HEADER.
791 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
792 Update limitations about when to call AC_CONFIG_HEADERS.
793 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
794 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
795 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
796 ``Configuration Actions''; fix their index entries.
798 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
799 options correctly. Process N-M as M-N if M is smaller than N.
800 Process ranges correctly so that N-N will run only N.
801 Sort and uniquify the tests that will be run. If there is more
802 than one test, reinsert the banners for the tests.
803 * tests/autotest.at (Keywords): Unmark XFAIL.
805 2005-08-23 Stepan Kasal <kasal@ucw.cz>
807 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
808 before passing the macro name to AH_TEMPLATE.
810 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
811 now opens log after option processing; in particular, --version
812 and --help do not touch config.log.
814 * Makefile.maint: Revert the change from 2005-08-12.
816 2005-08-22 Stepan Kasal <kasal@ucw.cz>

820 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
822 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
824 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
825 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
828 * doc/autoconf.texi (Defining Symbols, Changed Results):
829 Prepend to LIBS, not append, in examples.
831 2005-08-16 Stepan Kasal <kasal@ucw.cz>
833 When building in place, set srcdir="."; suggested by Tim Van Holder.
835 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
836 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
837 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
838 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
839 does not mean "no --srcdir option".
841 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
843 * tests/autoscan.at (autoscan): New file.
844 * tests/suite.at: Use it.
845 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
846 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
848 * tests/autotest.at (Keywords): Test keywords combinations.
850 2005-08-12 Stepan Kasal <kasal@ucw.cz>
852 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
853 add "2>&1"; gzip 1.2.4 prints help on stderr.
855 2005-07-27 Stepan Kasal <kasal@ucw.cz>
857 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
858 was pushdef'ed twice while popped only once. Push it only once.
859 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
861 2005-07-26 Stepan Kasal <kasal@ucw.cz>
863 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
864 prefixed by mere "===", not "configure: === ".
866 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
868 * Makefile.maint: Update from Bison.
870 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
871 "<tab>" in comment, so that the point is understandable.
873 2005-07-25 Stepan Kasal <kasal@ucw.cz>
875 Rewrite substantial part of lib/autoconf/status.m4.
876 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
877 and CONFIG_COMMANDS are not processed in four separate loops.
878 Instead, there is one main loop. This alows that the common code
879 is expanded only once, thus config.status (and configure) is smaller.
881 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
882 the AC_LIST_FILES and cousins macros are no longer used.
884 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
885 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
886 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
887 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
888 contain the initialization, nor the for loop, nor the associated
889 commands; all these go to ...
890 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
891 _AC_OUTPUT_CONFIG_STATUS.
892 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
893 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
894 (_AC_OUTPUT_FILE): The creation of the sed script ...
895 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
896 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
897 _AC_OUTPUT_MAIN_LOOP.
898 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
899 _AC_CONFIG_COMMANDS): Use ...
900 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
901 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
902 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
903 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
904 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
905 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
907 (_AC_CONFIG_UNIQUE): Update.
908 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
910 (_AC_LIST_TAGS): ... new common macro.
911 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
912 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
913 (_AC_LIST_TAG_COMMANDS): ... new common macro.
914 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
915 this didn't belong to the `config commands' section.
916 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
917 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
918 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
919 to the `config commands' section either.
920 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
921 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
923 ... and many changes to the comments nearby.
925 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
926 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
927 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
928 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
929 (#define header templates): The comment at the top of the generated
930 header now includes the name(s) of the source file(s).
932 Several unrelated small changes:
934 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
935 parameter to AC_DIAGNOSE.
936 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
937 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
938 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
939 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
941 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
942 in AC_OUTPUT doesn't double-quote it either.
943 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
946 2005-07-10 Stepan Kasal <kasal@ucw.cz>
948 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
949 versions of Portland Group compiler produce single- and double-quoted
950 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
951 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
953 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
955 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
956 This is a corrected version of yesterday's patch.
958 2005-07-07 Stepan Kasal <kasal@ucw.cz>
960 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
961 path, too; insert a "===" to emphasize the line.
963 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
964 ac_cv_build_alias to ac_build_alias.
965 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
967 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
968 change eliminates it. Problem reported by Alexandre Duret-Lutz.
969 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
970 (AC_ARG_VAR): ... here.
971 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
974 Keep a list of all precious variables and process them with one simple
975 for loop, instead of expanding all commands, or, OTOH, complicated
976 processing of output of "set".
977 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
978 variable names in new macro...
979 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
980 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
981 a loop to assign all ac_env_* and ac_cv_env_* variables.
982 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
984 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
985 its value to shell variable ac_precious_vars and call
986 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
987 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
988 _AC_ARG_VAR_VALIDATE.
990 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
991 and the AC_SUBSTs ...
994 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of

1034 sed substitution command, so that we allow | in program prefixes
1035 and program suffixes. (& is a problem anyway; we're not fixing

1038 configure_input, top_builddir, srcdir, etc.
1039 * lib/autotest/general.m4 (AT_INIT): Likewise, for

1101 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
1102 (AC_SUBST): Call it.
1103 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
1104 the directory specific variables; but don't call it for configure_input.

1108 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
1111 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
1113 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

1131 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
1132 variable into diagnostic. Make the diagnostic an error, not a warning,
1133 because we really don't support spaces and suchlike in dir names.
1134 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
1135 Don't worry about backslashes in srcdir; it can't happen now.

1154 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

1164 (Special Shell Variables): Fix sed code this in the example.
1165 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
1166 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
1168 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

1176 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
1178 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
1179 * doc/autoconf.texi:
1180 Don't mention Solaris versions so much, if a
1181 problem is common to all extant versions of Solaris. Say "SunOS
1182 4" instead of "SunOS" for SunOS 4.
1183 (awk): Mention more of the limitations of traditional Awk.
1184 (cat): Don't talk about cat -v.

1200 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
1202 * doc/autoconf.texi: "filesystem" -> "file system".
1203 "behaviour" -> "behavior".
1204 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
1205 * lib/autoconf/general.m4: Omit blank after ":" sed command,
1207 * lib/m4sugar/m4sh.m4: Likewise.

1209 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
1211 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.

1224 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
1226 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
1227 -u, since it outputs chatter if the input files are the same.
1228 Problem reported by Ralf Menzel.
1230 2005-06-08 Derek Price <derek@ximbiot.com>
1232 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
1233 renaming them since they are about to be redefined anyhow.
1235 2005-06-08 Derek Price <derek@ximbiot.com>
1237 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
1238 redefined M4 macros to this node. Document m4_include & m4_sinclude.
1239 Move m4_undefine to alphabetical order.
1241 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
1243 * README: Recommend GNU M4 1.4.3 or later.
1244 * doc/autoconf.texi (Introduction): Likewise.
1245 Reword to avoid some formatting glitches.
1246 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
1247 Clarify explanation of HP compiler bug.
1248 Redo example output tp match current CVS snapshot.
1249 Use @example.org in email addresses when the examples
1250 might get inadvertently cut-and-pasted into user code.
1251 Remove example of autom4te usage that doesn't seem to work now.
1252 Use modern AC_INIT (except when the example is meant to be
1253 shown with Autoconf 2.13).
1254 Update ksh info for Solaris 9 and later.
1256 Modernize description of Automake versions a bit.
1257 Don't claim a future version of Autoconf is near.

1263 follows its own advice about quoting better.
1264 Reword to avoid some formatting glitches.
1265 * doc/installt.exi: Reword to avoid some formatting glitches.
1267 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
1268 Tru64 ksh pattern matching bug. Reported against Libtool by
1269 Albert Chin <libtool@mlists.thewrittenword.com> and
1270 Nicolas Joly <njoly@pasteur.fr>.
1272 2005-06-06 Stepan Kasal <kasal@ucw.cz>
1274 m4_cdr of one-member list was [[]] (one-member list containing an
1275 empty string) instead of [] (an empty list. Callers were skewed to
1276 match this misbehaviour. As a consequence of this:
1277 - m4_foreach([x], [], [foo]) expanded to `foo', while
1278 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
1279 This bug has been fixed:
1281 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
1282 expand to an empty string; print error msg if called without
1284 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
1285 misbehaviour; handle [] and [[]] correctly.

1293 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
1295 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
1296 swallow records with more than 99 fields.
1297 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
1298 parse the long line.
1300 2005-06-04 Stepan Kasal <kasal@ucw.cz>
1302 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
1303 swallow literals longer than 399. Reported by Ralf Wildenhues.
1304 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

1307 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
1309 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
1310 to gfortran, and make these the first two compiler names

1315 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).

1322 expression of unbounded size when processing the --list
1323 option. This runs afoul of a limit of 399 bytes per regular
1324 expression on AIX. Problem reported by Ralf Wildenhues.
1326 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

1337 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
1338 now contain newlines, and substituted files must be referenced on
1339 a line alone; the sed scripts to substitute them are now very
1341 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
1342 commands can be put in a sed script portably.
1343 * doc/autoconf.texi (Setting Output Variables): Document above
1344 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
1345 use of multiline substitution.

1356 classes in shell scripts. The test was too brittle.
1358 2005-05-25 Stepan Kasal <kasal@ucw.cz>
1360 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
1361 * doc/autoconf.texi (Limitations of Builtins): Document this
1364 2005-05-24 Stepan Kasal <kasal@ucw.cz>
1366 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
1367 common code; used in many places in the tree.

1374 messages when ac_unique_file is not found.
1375 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
1376 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
1377 commands, for consistency with AC_MSG_ERROR and such.

1392 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
1393 (ac_top_builddir): ... this ...
1394 (ac_top_build_prefix): ... to this; the old name is also kept, for
1395 backward compatibility.

1412 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
1413 argument to m4_foreach. I guess it was necessary in the past,
1414 but I think it's a no-op now.

1418 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
1419 ``cat <<_ACEOF'' commands to one.

1425 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
1427 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

1497 * doc/autoconf.texi (Autoconf Language): Be more precise about
1498 quoting rules. Problems noted by Stepan Kasal.
1499 Also, throughout this document, be more careful about white space.
1500 "blank", "white space", and "space" all have different meanings
1501 and we should be careful to say what we mean.

1521 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
1522 set by latest automake.
1524 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
1526 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
1527 outputs 0 on GNU/Linux these days.

1540 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
1541 by AC_DEFINE; it was a mistake.
1542 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
1544 2005-04-25 Stepan Kasal <kasal@ucw.cz>
1546 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
1548 2005-04-22 Stepan Kasal <kasal@ucw.cz>
1550 * doc/autoconf.texi (External Software): Quadrigraphs are not
1551 processed correctly in AS_HELP_STRING; avoid this in the examples.
1552 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
1553 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
1554 comment and reduce m4_default([foo], []) to [foo].
1555 (m4_strip): Update the explanation.
1557 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
1559 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):

1561 Problem reported by Jennis Pruett.
1562 * lib/autoconf/functions.m4
1563 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

1613 whole-archive (-zallextract, -zdefaultextract) options in the hope of
1614 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
1615 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
1617 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
1619 * NEWS: The configure command now warns you if you attempt to use
1620 a directory whose name contains a special character like space,
1622 * doc/autoconf.texi (Installation Directory Variables): Allow
1623 "," in file names. Do not use \@; it's not a portable regexp.

1632 unportable file names.
1633 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
1635 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
1636 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
1637 ac_pwd, and quote srcdir.
1638 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
1640 * doc/autoconf.texi: Fix some systematic formatting problems.
1641 ".)" needs a following @: if not at the end of a sentence, and
1642 similarly for "!)". "etc." should be preceded by a comma.
1643 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
1645 2005-03-22 Bruno Haible <bruno@clisp.org>
1647 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
1648 argument is often called 'build-aux'.
1650 2005-03-07 Stepan Kasal <kasal@ucw.cz>
1652 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the

1654 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
1657 2005-02-24 Stepan Kasal <kasal@ucw.cz>
1659 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
1660 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
1661 from a Common Lisp's `cl'.
1662 (AC_PROG_CXX): Behave according to the documentation: don't
1663 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
1664 make the variable CCC precious; use `cl.exe', not `cl'.
1666 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
1667 Alexandre Duret-Lutz <adl@gnu.org>
1669 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
1670 /dev/null, as "configure" shouldn't read stdin, and this insulates
1671 us from problems (e.g., when testing for "cl"). Also, do this
1672 redirection before invoking "hostname" or "uname", and keep the
1673 original input stream available via...
1674 (AS_ORIGINAL_STDIN_FD): ... this new macro.
1675 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

1687 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
1688 newline if neither \c nor -n work, as that would output two
1689 newlines. Prefer -n to \c. Reported by Stepan Kasal.
1691 2005-02-12 Stepan Kasal <kasal@ucw.cz>
1693 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
1694 This causes that any required macros inside will get before the if.
1695 * doc/autoconf.texi (autom4te.cache): A typo.
1697 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
1699 Undo previous change, except keep the change to
1700 lib/autoconf/programs.m4 that replaced grep with shell
1701 pattern-matching. This is because net-snmp configure reads stdin.
1702 Reported by Noah Misch.
1704 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
1706 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
1707 from /dev/null, as "configure" shouldn't read stdin, and this
1708 insulates us from problems (e.g., when testing for "cl").
1709 Suggested by Alexandre Duret-Lutz. Also, do this redirection
1710 before invoking "hostname" or "uname".
1711 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
1712 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
1713 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
1714 "</dev/null" since it's now done at the top of 'configure'.
1715 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1716 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
1717 Also, replace grep with shell pattern-matching, to save a process.
1719 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
1721 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
1722 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
1723 avoid thinking that Allegro Common Lisp's "cl" command is a C++
1726 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
1728 * doc/autoconf.texi (Limitations of Usual Tools): Document that
1729 grep -q isn't portable. Improve grep -s explanation.
1730 Problem reported by Dan Manthey.
1732 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
1734 * doc/autoconf.texi (Special Shell Variables): Clarify
1735 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
1737 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
1739 * doc/autoconf.texi: Use @acronym for DJGPP.
1740 Fix some @code's that should have been @env's, and vice versa.
1741 Sort environment variable names.
1742 Mention that shells no longer inherit IFS.
1743 Don't recommend PATH_SEPARATOR=';' so strongly.
1744 Mention that $RANDOM might expand to the empty string.
1745 "symlink" and "soft link" -> "symbolic link".
1746 Improve mktemp description (reported by Bruno Haible).
1748 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
1750 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.

1782 excess test name quoting.
1783 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass

1786 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not

1822 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
1824 Try not to generated lines of unlimited length, as POSIX places a
1825 2047-byte limit on line length of portable text files.
1826 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
1827 Use newline as a separator, not space.

1885 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
1886 Update the long comment explaining it.
1888 m4_require no longer writes an ``is required by'' line to the
1889 execution stack. It contains only one bit of non-redundant
1890 information: that the macro was required, not called. And even
1891 this bit is useless in most situations: have you ever met a macro
1892 which both calls and requires the same macro?
1894 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
1895 (_m4_defun_pro_outer): ... only via this macro, for the outermost
1897 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
1898 (m4_expansion_stack_pop): Remove the misplaced comment.
1899 (m4_require): Don't put the ``is required by'' line to the
1900 execution stack; slightly improve the out-of-a-defun error message.
1901 (_m4_divert_grow): New macro, counter for the temporary diversions.
1902 (_m4_require_call): Use it.
1903 * tests/m4sugar.at (m4_require): Expect output without the
1904 ``is required by'' messages.
1906 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
1908 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X

2381 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
2382 the $1_found variable, don't test whether the file is executable;
2383 Both things are checked ...
2384 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
2385 the former ``test -f''.
2386 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
2388 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

2395 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
2396 limitations. Reorder paragraphs for clarity.
2398 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
2400 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
2401 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
2402 variants", "Unix", and some related minor wording fixups.
2404 (Shellology, Special Shell Variables): Document that the Zsh
2405 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
2406 to Alexandre Duret-Lutz for this info.
2408 2004-10-10 Alexandre Duret-Lutz <adl@gnu.org>

2417 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
2419 * doc/autoconf.texi (auindex): New macro.
2420 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.

2427 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
2429 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
2430 readable; it's not true in OS/2-emx.
2432 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
2434 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
2435 "/usr/include", clear ac_x_includes instead of leaving it as "no"
2436 (trivial change). Problem and patch reported by Andrew Church in:
2437 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
2439 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

2460 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
2464 * README: Add advice about m4 1.4.2.
2466 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
2467 texinfo.tex for now (done by hand now).
2468 * Makefile.maint (wget_files, cvs_files):
2469 Remove ansi2knr.c; nobody uses it.
2470 (ansi2knr.c-url_prefix): Remove.
2471 (cvs-update): Fix test for failure. I don't know why it ever
2474 * doc/autoconf.texi: Update URLs, some of which went stale.
2475 Use @uref rather than @href.
2477 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
2478 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
2480 * config/config.guess, config/config.sub, config/elisp-comp,
2481 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
2482 doc/fdl.texi, doc/standards.texi: Sync with master copy.
2484 * NEWS, TODO, configure.ac, bin/autoscan.in,
2485 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
2486 doc/install.texi, lib/Autom4te/Configure_ac.pm,

2490 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
2491 tests/tools.at, tests/torture.at:
2492 Use "file name" rather than "filename" or "path",
2493 to be consistent with the terminology of the GNU coding standards.
2495 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
2497 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
2498 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
2499 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
2500 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
2502 More fixes to support spaces in the name of the build directory.
2503 This isn't a complete fix but it's an improvement.
2505 * bin/autoconf.as (autom4te_options): New var.
2506 Use it instead of appending to AUTOM4TE, so that we can allow
2507 spaces in the build directory's absolute name.
2508 * bin/autoheader.in ($autoconf): Allow spaces in file names.
2509 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
2510 AT_CHECK_NOESCAPE): Likewise.
2511 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
2512 main program): Likewise.
2514 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
2516 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

2522 * doc/autoconf.texi (Function Portability): Document isinf and
2523 and isnan. From a suggestion by Kevin Ryde.
2525 * lib/Autom4te/General.pm (END): Return correct exit status even
2526 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
2528 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
2530 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
2531 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
2532 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
2534 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
2536 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
2537 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
2538 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
2539 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
2540 * lib/autom4te.in (Automake-preselections): Preselect
2541 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
2543 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
2545 * lib/autom4te.in (Automake-preselections): Preselect
2546 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
2549 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
2551 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
2553 * doc/autoconf.texi (Shellology): Mention BIN_SH.
2554 Document problem with "`""`" in pdksh POSIX mode.
2556 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
2558 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
2559 with pdksh, too. Problem reported by Patrick Welche via
2561 * doc/autoconf.texi (Shellology): Note that set -o posix is
2562 useful for pkdsh, too.
2564 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
2566 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
2567 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
2568 Don't fail if ENV or BASH_ENV is readonly.
2569 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
2570 etc. are read only. Problem reported by Ludovic Courtes.
2572 2004-06-23 Noah Misch <noah@cs.caltech.edu>
2574 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
2575 zsh, disable GLOB_SUBST to avoid backslash handling problems.
2578 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
2580 * doc/autoconf.texi (File System Conventions): Warn about
2581 names like "aux". Problem reported by Eric Blake.
2583 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
2584 by zero instead of array size, so that we can use any arithmetic
2585 constant expression (instead of requiring an integer constant
2586 expression). This allows us to test expressions like DBL_MAX <
2587 LDBL_MAX, which didn't conform to the C standard using the old
2589 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
2590 now that we can do floating-point tests at compile time.
2592 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
2594 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
2595 and LDBL_EPSILON, as the resulting expression isn't an
2596 integer constant expression and violates the C standard.
2597 Problem reported by Nelson H. F. Beebe. Also, check
2598 for "L" suffix, and check that long double doesn't have
2599 worse range or precision than double, that mixed-mode
2600 arithmetic doesn't generate a diagnostic, that double
2601 constants fit in long double.
2603 2004-06-03 Kevin Ryde <user42@zip.com.au>
2605 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
2606 malloc(0) and realloc(NULL,size).
2608 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
2611 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
2613 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
2614 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
2617 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
2619 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
2620 can be rewritten using if-then-else. Suggested by Bruno Haible.
2622 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
2624 * doc/autoconf.texi (testsuite Scripts): Fix typo.
2625 Problem reported by Stepan Kasal.
2627 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
2629 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
2630 change). Patch reported by Ralf Wildenhues in
2631 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
2633 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
2634 function F exists if the compiler and linker let you compile an
2635 expression like (F != 0). Recent versions of GCC optimize away
2636 the reference to F in that case, since every function address must
2637 be nonzero, so the link succeeds even if F does not exist.
2638 Problem reported by Manu in
2639 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
2641 * doc/autoconf.texi (Systemology): Standardize on the spelling of
2642 "Unix". Many uses changed.
2643 (Limitations of Builtins): Explain better why the ! command isn't
2646 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
2648 * lib/autom4te.in (Automake-preselections): Preselect
2649 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
2651 2004-05-19 Kevin Ryde <user42@zip.com.au>
2653 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
2654 referencing AC_FUNC_STRERROR_R.
2656 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
2657 note pessimistic assumption when cross compiling.
2659 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
2661 * doc/autoconf.texi (Limitations of Make): Note that BSD make
2662 (until 2004) invoked subcommands with sh -e, contra POSIX.
2663 Reported by Kevin Ryde.
2665 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
2667 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
2668 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
2669 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
2670 `test -f " /usr/bin/grep"', which _always_ failed.
2671 (AC_PROG_SED): Ditto bogus PATH fix.
2672 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
2673 requires that grep correctly supports _multiple_ `-e' options, rather
2674 than stating only that grep should accept `-e'.
2676 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
2678 Port to C99, which requires that 'exit' be declared.
2680 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
2681 to ensure that stdlib.h is included.
2682 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
2683 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
2684 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
2685 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
2686 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
2687 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
2688 when using 'exit' in a test; C99 requires that 'exit' be declared.
2690 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
2692 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
2693 now prefers 'grep' implementations that accept -e.
2694 (Limitations of Usual Tools): Describe problems of traditional
2695 egrep and fgrep with long input lines, and of traditional grep
2697 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
2698 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
2699 All callers changed. Append /usr/xpg4/bin to the PATH, for
2701 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
2702 the user with complaints about multiple -e options.
2703 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
2704 Define it with AC_PROG_GREP.
2705 * configure.ac (AC_PROG_GREP): Add.
2706 * lib/freeze.mk (GREP): New macro.
2708 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
2710 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
2711 a possible candidate only after all others fail, rather than
2712 consulting it first. This improves backward compatibility by
2713 better reflecting the way shell selection occurred in previous
2714 versions of Autoconf, and should help to avoid triggering latent
2715 problems in other packages, such as the one in Automake where zsh
2716 is not handled robustly:
2717 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
2718 Although it is not Autoconf's responsibility to work around
2719 problems in Automake, it nevertheless makes sense to avoid
2720 introducing unnecessary incompatibilites.
2722 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
2723 Gary V. Vaughan <gary@gnu.org>
2725 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
2726 how deeply nested we are when a suitable tool is found, set the
2727 ac_path_TOOL_found flag.
2728 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
2729 nested we are in this macro. Break out of all 3 nested loops if
2730 ac_path_TOOL_found is set.
2732 2004-04-21 Gary V. Vaughan <gary@gnu.org>
2734 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
2735 of the _AS_PATH_WALK loop too if GNU flavor is found.
2737 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
2739 * doc/autoconf.texi (Limitations of Make): Update documentation
2740 for `$<'. New entry `Long lines', based on a report from Simon
2741 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
2742 paragraph about DJGPP, based on a mail from Richard Dawe.
2744 2004-04-20 Paul Eggert <eggert@twinsun.com>
2746 * tests/c.at (C keywords): Don't assume that GCC supports
2747 "restrict" and "inline", as sufficiently-old GCC versions do not
2748 (also, GCC configured to be in pedantic C89 mode does not).
2749 Problem reported by Sumit Pandya in:
2750 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
2752 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
2753 consider -g to work if it generates warnings when plain compiles
2754 don't. Problem reported by Braden McDaniel in:
2755 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
2757 * doc/autoconf.texi (Slashes): New section, to document a problem
2758 reported by Jim Meyering in:
2759 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
2761 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
2762 linker output files before linking, to work around IRIX 6 linker bug.
2763 Problem reported by Rainer Orth in:
2764 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
2766 2004-04-20 Gary V. Vaughan <gary@gnu.org>
2768 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
2769 best tool so far counter rely on the tool path variable name to
2770 avoid checks for one tool being affected by the results of running
2771 the length check on a previous tool.
2773 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
2774 match expression argument, as different greps have different
2775 regular expression flavours.
2776 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
2778 (AC_PROG_EGREP): Pass 'EGREP$'.
2779 (AC_PROG_GREP): Pass 'GREP$'.
2781 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
2783 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
2784 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
2786 2004-03-29 Paul Eggert <eggert@twinsun.com>
2788 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
2789 Types, Specific Compiler Characteristics, System Services,
2790 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
2791 etc. consistently instead of 'long', 'short', 'unsigned' etc.
2792 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
2793 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
2795 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
2796 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
2797 AC_TYPE_OFF_T): Likewise.
2798 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):

2802 pacify libtool 1.5.2. Fix quoting problems in sed command.
2804 2004-03-28 Paul Eggert <eggert@twinsun.com>
2806 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
2807 now defines HAVE_DECL_TZNAME if it is declared, when
2808 HAVE_STRUCT_TM_TM_ZONE is not defined.
2809 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
2810 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

2815 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
2816 superfluous backslashing of quotes (") in sed expressions;
2817 thanks to Paul Eggert.
2819 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
2821 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
2822 Fortran compiler is ifort, also added pghpf; thanks to Nelson
2823 H. F. Beebe for the bug report.
2825 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
2827 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
2828 quoted -cmdline argument in Portland Group compiler (bug
2829 reported by Jeffrey J. Barteet).
2831 2004-03-25 Kevin Ryde <user42@zip.com.au>
2833 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
2834 (Run Time): ... here, where it's now mentioned.

2862 * doc/autoconf.texi: Avoid macros with unbraced arguments,

2879 * bin/Makefile.am (edit): Don't use $< in a context where
2880 POSIX doesn't require support for it. Use $@.in instead.
2881 Problem reported by Anthony N. Frasso in
2882 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

2899 problem on QNX reported by Stephen Rasku in
2900 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
2902 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

2911 AC_SUBST provides no portable way to escape literal newlines.
2913 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
2914 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
2915 Darwin uses -lcrt2.o and there's little point to cataloging all
2916 the system variants. Partial fix reported by Andreas Waechter in:

2941 Eric Sunshine <sunshine@sunshineco.com>

2992 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
2993 2003 (except 1997) to the list of copyright years. This undoes
2994 the 2003-05-22 change, which removed the older years from the list.
2995 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

3008 _AC_PROG_GREP, and AC_PROG_SED.

3041 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
3042 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
3043 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
3044 not <inttypes.h>. Problem reported by Tim Mooney in
3045 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
3046 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
3049 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
3050 otherwise "make check" fails because it forbids cmp (I guess
3051 because cmp treats files as binary on DOS-like systems).

3054 have changed in 2004.

3066 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
3067 -std1 disables some useful extensions on Tru64. Problem reported

3071 2004-01-14 Paul Eggert <eggert@twinsun.com>
3073 * doc/autoconf.texi (Programming in M4sh): Document that
3074 AS_MKDIR_P succeeds if the destination is a symbolic link
3075 to an existing directory.
3076 (Limitations of Usual Tools): Note that mkdir -p might not
3077 succeed on symlinks to directories.

3081 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

3097 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
3098 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
3099 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
3100 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
3101 AC_COMPILE_IFELSE, since we now assume our caller invokes
3102 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
3103 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
3104 of AC_RUN_IFELSE; this avoids the warning mentioned above.
3105 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
3107 2004-01-07 Paul Eggert <eggert@twinsun.com>
3109 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
3110 `"'...'"`, as it's confusing (and I suspect it may not work on
3111 some platforms). The code was incorrect anyway, as it assumed
3112 that \$ evaluated to itself in that context. Reported by
3113 Alexandre Duret-Lutz.
3115 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
3117 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

3147 Bug reported by David Relson in
3148 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
3150 * Makefile.am (autom4te-update):
3151 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

3167 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
3168 -c -o might not work. From a suggestion by Kevin Ryde.
3169 (C Compiler, Generating Sources, Limitations
3170 of Usual Tools, Limitations of Make, Making testsuite Scripts):
3171 Don't put '-o' after non-options, as POSIX doesn't allow this.
3172 Mention that cc's name might be gcc or c89 or whatever.
3174 2004-01-04 Kevin Ryde <user42@zip.com.au>

3183 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
3185 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
3186 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
3187 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
3188 explanation clearer.

3469 Problems reported by Eric Sunshine.
3471 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
3473 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
3474 -mGLOB_options_string stuff for Intel ifc, which can cause
3475 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

3496 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
3498 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
3499 cache variable instead of $G77 to decide whether to include -O2,
3500 since $G77 is specific to Fortran 77.
3502 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
3504 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
3505 free" flag. Re-order flags tested into rough order of popularity.
3507 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
3509 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
3510 arguments so that it can be used with syntax identical to

3586 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
3587 directory for AC_CONFIG_COMMANDS' first argument exists.
3588 This makes valid the invocation of _AC_SRCPATH that follows.

3613 The test suite are sometimes assigning timings incorrectly.
3614 Reported by Henk Krus.
3615 Diagnosed by Nicolas Joly.
3617 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
3619 Instead of making AT_help a sequence of assignments to grow

3621 $at_help_all, and make a single assignment in...
3623 (at_times_skip): Flip the meaning and rename as...

3635 (ifnames): chmod -w.
3636 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
3637 executables, not bin/ executables! Otherwise all the magic needed
3638 to find non installed files is turned off. This caused a failure
3639 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
3640 as found in its environment (sent by tests/autoreconf): pointing
3641 to bin/autom4te that could not find its files.
3642 * tests/mktests.sh: Force the replacement of generated files, for
3643 the sake of "mv" program that are interactive when overwriting a

3742 correspond to all the old F77 macros, with output variables FC,
3743 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
3744 available dialect, but older dialects can be specified. There are
3745 new macros AC_FC_SRCEXT to set the source extension, and
3746 AC_FC_FREEFORM to accept free-form source files.

3833 (local-checks-available): this.
3836 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
3837 * configure.ac: Require Automake 1.7.6.
3839 2003-08-22 Akim Demaille <akim@epita.fr>
3841 Output stack traces in warnings.
3843 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
3844 Replace the former...
3845 (m4_warn): Pass the call stack to _m4_warn.
3846 * bin/autom4te.in: Adjust to output the call stack.
3847 * tests/m4sugar.at (m4@&t@_warn): Adjust.
3849 2003-08-22 Akim Demaille <akim@epita.fr>
3851 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.

3862 Use &verb, not &verbose.
3864 2003-08-21 Akim Demaille <akim@epita.fr>
3866 * bin/autoheader.in (&parse_args): Use &parse_warnings and
3868 ($help): Use Autom4te::ChannelDefs::usage.
3869 * bin/autoscan.in: Use Autom4te::ChannelDefs.
3870 * lib/Autom4te/General.pm: Don't export error: you don't own it.
3872 2003-08-21 Akim Demaille <akim@epita.fr>
3874 First stab at preserving warnings between calls to autom4te,
3875 including when the cache is used.
3877 There are still several issues: (i) there are too many runs of m4
3878 (one for include, one for warnings, and some more), (ii) warnings
3879 spreading on several lines are not handled gracefully, (iii) the
3880 code meant to have the call stack display for errors does not work
3881 (its handling should move from m4 to autom4te).
3883 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
3885 (@preselect): Add m4_warn.
3886 ($exit_status): Remove, use $exit_code.
3887 ($help): Use Autom4te::ChannelDefs::usage.
3888 (&handle_m4): No longer define the m4_warnings.
3889 At each run, extract and report the warnings.
3890 Always cache the result, including if the exit status is on
3891 failure, since if nothing changes, we should result in the same
3892 failure, hence we can use the cache.
3893 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
3894 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
3896 (m4_warn): Redefine as a do-nothing: it is its invocation that
3897 matters, as warnings are now reported via traces.
3898 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
3899 the contents of m4_warn: make it _call_ m4_warn, so that tracing
3900 the latter reveals calls to the former.
3904 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
3906 2003-08-21 Akim Demaille <akim@epita.fr>
3908 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
3911 2003-08-21 Akim Demaille <akim@epita.fr>
3913 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
3915 * lib/Autom4te/ChannelDefs.pm: Doc typos.
3916 (&parse_warnings): Accept a list of warning requests.
3917 (&usage): Return a string, not a side effect.
3918 (cross): New warning category.
3920 2003-08-21 Akim Demaille <akim@epita.fr>
3922 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
3923 (&require_configure_ac): Accept an optional directory argument.
3924 ($configure_ac): Remove.
3925 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
3927 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
3928 * bin/autoscan.in: Adjust.
3930 2003-08-20 Akim Demaille <akim@epita.fr>
3932 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
3933 Reported by Alexandre Duret-Lutz.
3935 2003-08-20 Akim Demaille <akim@epita.fr>
3937 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
3938 * bin/autom4te: Adjust.
3939 In particular, be Autoconf tools are really silent when properly
3940 working, bind the verbosity of the 'note' channel to $verbose.
3941 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
3942 (&xsystem, &contents): Remove, since they are exported by...
3943 * lib/Autom4te/FileUtils.pm: this.
3945 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
3946 * lib/Autom4te/FileUtils.pm: here.

4001 2003-08-14 Derek Price <derek@ximbiot.com>
4003 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
4004 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
4005 shorter column three. Add DESCRIPTION to log file content.
4007 2003-08-13 Derek Price <derek@ximbiot.com>
4009 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
4012 2003-08-12 Derek Price <derek@ximbiot.com>

4027 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
4029 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
4031 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
4032 -lcrt1.o, for OS X. (trivial change)
4034 2003-07-07 Paul Eggert <eggert@twinsun.com>
4036 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
4037 inside '#ifndef __cplusplus'. Problem reported by
4040 2003-07-06 Bill Clarke <llib@computer.org>
4042 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
4043 'long', not 'int', for benefit of Sun's recent C++ compilers
4044 (trivial change). See:

4060 * doc/autoconf.texi (Header Portability): sys/mount.h.
4061 From Gareth McCaughan.
4063 2003-06-23 Akim Demaille <akim@epita.fr>
4065 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
4066 not all of them. This fixes 1. the fact that when testing
4067 Autoconf there are many many config.log, 2. the incorrect use of
4068 top_srcdir to find config.log.
4069 Don't mix the detailed output of failed test with the summary of
4070 failures. Rather, append detailed log afterwards.
4072 2003-06-23 Akim Demaille <akim@epita.fr>
4074 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
4075 always run: output config.log on $at_group_log.
4077 2003-06-23 Akim Demaille <akim@epita.fr>
4079 * tests/torture.at (#define header templates): Don't use quotes in

4095 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
4096 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby

4133 (AT_INIT): Support for expected failures.

4157 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
4159 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
4160 Do not call `_exit()', simply modify `$?'.
4161 (xsystem): Reset $! before running system, and check it afterward.
4162 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
4163 63 for version mismatches.
4165 2003-05-23 Akim Demaille <akim@epita.fr>
4167 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
4168 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
4169 the middle of a line).
4170 * lib/m4sugar/m4sugar.m4: Likewise.

4187 Paul Eggert <eggert@twinsun.com>
4189 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
4190 Remove `#include <stdlib.h>' from the list; we should never
4191 make confdefs.h include <stdlib.h> or <cstdlib>, because the
4192 resulting namespace pollution would cause other tests to fail.
4193 Configure scripts run with some older versions of g++ and HP's
4194 aCC would fail due to such an #include. Problems reported by
4195 Matthew Mueller in <http://bugs.debian.org/120704> and by
4197 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
4198 In the test, use the test declaration before including <stdlib.h>,
4199 as that's closer to how it'll be used.

4208 Overhaul Autotest's logging: generate separate log files
4209 in testsuite.dir/NNN/testsuite.log, and append them to
4210 testsuite.log instead of re-running the test verbosely.
4212 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
4213 file descriptor, write 0 to at_status_file instead of setting
4214 at_status=0, initialize some new variables (at_status_file,
4215 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
4216 to rerun the tests, instead append the at_group_log to the
4217 at_suite_log when a test fails.
4218 (AT_SETUP): pipe the test case's output into at_tee_pipe,
4219 with the AS_MESSAGE_LOG_FD redirected to stdout.
4220 (AT_CLEANUP): save the output status in $at_status_file
4221 and restore it, redirect the AS_MESSAGE_LOG_FD back to
4223 (AT_CHECK): since tests are run with a redirected stdout,
4224 and used to be re-run in verbose mode, turn some $at_verbose
4225 into echo, and don't redirect the output of testing stdout
4228 * lib/autotest/autoconf.texi (testsuite Scripts): Update

4349 2003-05-06 Akim Demaille <akim@epita.fr>
4351 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
4352 longer updates aclocal.m4 if useless, (ii) if a file m4_included
4353 by aclocal.m4 is changed it might require the importing of another
4354 m4 extension file, i.e., aclocal must be run.
4356 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
4357 (&parse_args): Use --force with aclocal if required and supported.

4375 (AT_CLEANUP): Add `;' to end of at_help_all.
4376 (AT_INIT): Allow --keywords to be specified more than once. When
4377 grepping $at_help_all for keywords, use the field and keyword

4529 about `$<' in inference rules, it was a bogus interpretation of
4530 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
4531 Tru64 make in the "target lookup" section.
4532 (Automake): Automake 1.5+ no longer requires special tools to be
4533 present on the developer's host.
4535 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
4537 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
4538 to a shell that can handle redirection or quoting correctly.
4539 Override SHELL with the shell detected by configure.
4540 Use of $^O suggested by Tim van Holder.
4541 * bin/autom4te.in (BEGIN): Likewise.

4573 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
4574 to fix a mismatch between example and discussion.
4576 2003-02-24 Kevin Ryde <user42@zip.com.au>
4578 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
4579 format starting with "-".

4589 compiler says yeah, but preproc says nope, compiler is right.
4590 Conversely, prompt the reader to send a bug report to the
4591 maintainers of the package, not of Autoconf.
4593 2003-02-20 Klee Dienes <kdienes@apple.com>
4595 * bin/autoreconf.in (autoreconf_current_directory): Properly

4604 2002-12-23 Paul Eggert <eggert@twinsun.com>
4606 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
4607 innocuous variant befor including <limits.h> or <assert.h>. This
4608 works around a bug reported by Albert Chin: HP-UX 11i
4609 (and earlier versions) have a <limits.h> that declares
4610 gettimeofday and many other functions.
4612 2002-12-03 Paul Eggert <eggert@twinsun.com>
4616 * NEWS, configure.ac: Update version.
4618 * doc/fdl.texi: Upgrade to FDL version 1.2.
4620 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
4621 nontrivially in main's body, so that f's external declaration is
4622 not optimized away in AIX. This should fix the bug reported by
4624 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.

4627 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
4628 defined, to support freestanding compilers. This should fix the
4629 bug reported by Momchil Velkov in
4630 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
4632 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
4633 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

4644 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
4645 \(.*\) match is too long and there is something more to be checked.

4664 Update from masters.
4666 2002-11-14 Akim Demaille <akim@epita.fr>
4668 * Makefile.maint: Sync with Bison, i.e.:
4669 (po-check): Scan .l and .y files instead of the
4670 .c and the .h files that they generate. This fixes the bug
4671 reported by Tim Van Holder in:
4672 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
4673 Look for N_ as well as for _. Try to avoid matching #define for

4680 From Paul Eggert and Albert Chin-A-Young.
4682 2002-11-14 Akim Demaille <akim@epita.fr>
4684 * doc/autoconf.texi (C Compiler): Solitary backslashes.
4685 From Paul Eggert and Albert Chin-A-Young.
4687 2002-11-14 Kevin Ryde <user42@zip.com.au>
4689 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
4690 than assigning in main, to avoid HP cc +O3 optimizing it away.
4692 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
4694 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
4695 option. Process --recheck after parsing all options. Pass -q
4696 option to configure on --recheck.
4697 (AC_OUTPUT): Pass -q from configure to config.status.
4698 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
4699 arguments to record.
4700 * doc/autoconf.texi (config.status Invocation): Document
4701 config.status -q option.

4728 Reported by Ezra Peisach.
4730 2002-11-05 Akim Demaille <akim@epita.fr>
4732 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
4734 We _have_ to stop using the old compatibility scheme that tried to
4735 avoid useless backslashes because Libtool 1.4.3 contains a
4736 AC_DEFINE([error_t], [int],
4737 [Define to a type to use for \`error_t' if it is not
4738 otherwise available.])
4739 We _have_ to quote the single quote and backslashes with \. The
4740 old compatibility scheme saw that ` was backslashed, and therefore
4741 did not quote the single quote. Hence before this patch, Autoconf
4742 was not compatible with Libtool.
4744 2002-11-04 Paul Eggert <eggert@twinsun.com>
4746 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

4761 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
4763 (&autoreconf): here.
4764 ($help, $make, &parse_args, &autoreconf_current_directory):
4766 * doc/autoconf.texi (autoreconf Invocation): Adjust.
4768 2002-10-31 Bruno Haible <bruno@clisp.org>
4770 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.

4784 2002-10-31 Akim Demaille <akim@epita.fr>
4786 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
4787 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
4788 Make variable, not a shell variable.
4789 Suggested by Bruno Haible.
4791 2002-10-31 Akim Demaille <akim@epita.fr>
4793 * bin/autom4te.in (load_configuration): Reject #args out of any
4796 2002-10-31 Akim Demaille <akim@epita.fr>
4798 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
4799 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
4800 (_AC_RUN_IFELSE): Use it.
4801 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
4802 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.

4810 Suggested by Tim van Holder.
4812 2002-10-29 Paul Eggert <eggert@twinsun.com>
4814 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
4815 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
4816 Problem reported by Bruno Haible.
4818 2002-10-29 Akim Demaille <akim@epita.fr>
4820 * doc/autoconf.texi (Header Templates): Put also in words what the
4821 pictures says to assist free style readers.
4822 (Customizing autom4te): s/--cache=/--cache /.
4824 2002-10-29 Akim Demaille <akim@epita.fr>
4826 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
4828 sparc_address_test returns void.
4829 Use it with an argument, as prototyped.
4832 2002-10-29 Akim Demaille <akim@epita.fr>
4834 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

5355 (Limitations of Make): Some about `Single Suffix Rules and
5356 Separated Dependencies'.
5357 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
5358 (ifnames, autoscan, autom4te): Un-factor into several rules.
5360 2002-09-25 Paul Eggert <eggert@twinsun.com>
5362 * BUGS (Interoperability bugs): New section. Mention libtool
5363 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
5365 2002-09-24 Paul Eggert <eggert@twinsun.com>

5368 make handles suffix-rules differently from GNU make.
5370 * bin/Makefile.am (SUFFIXES, .in): Remove.
5371 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
5372 Move the body of the old .in rule here.

5376 i960 compilers create `b.out' files by default.
5377 Reported by Ralf Corsepius.
5379 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
5380 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.

5396 2002-09-13 Akim Demaille <akim@epita.fr>
5398 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
5399 reading config.log when the compiler is rejected.
5400 Suggested by Guido Draheim.
5402 2002-09-13 Akim Demaille <akim@epita.fr>
5404 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
5405 (chdir_init) might hang when stat'ing mounted directories.
5406 Reported by Vance Shipley.
5408 2002-09-12 Akim Demaille <akim@epita.fr>
5410 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not

5415 * doc/autoconf.texi (Defining Symbols): Present two different
5416 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
5417 difference between 1 argument calls, and 2-3 argument calls.
5419 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
5421 * doc/autoconf.texi: Review grammar and punctuation.
5423 2002-09-11 Paul Eggert <eggert@twinsun.com>
5425 * doc/autoconf.texi: Fix minor formatting, spelling, and
5427 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
5428 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
5431 2002-09-11 Akim Demaille <akim@epita.fr>
5433 * doc/autoconf.texi (Questions): Rename as...
5435 (Defining Directories): New.
5437 2002-09-09 Akim Demaille <akim@epita.fr>
5439 * doc/autoconf.texi (Making testsuite Scripts): Update.
5440 Suggested by Nishio Futoshi.
5442 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
5444 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
5445 plain `@' is wanted.
5447 2002-09-09 Akim Demaille <akim@epita.fr>
5449 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
5450 `duplicates', since the algorithm was too naive and could keep
5451 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
5452 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
5453 Reported by Ralf Corsepius.

5462 directory is relative.
5463 * doc/autoconf.texi (Generic Functions): Clarify the replacement

5470 precious variables are.
5471 Suggested by Pontus Skoeld.
5473 2002-09-05 Akim Demaille <akim@epita.fr>
5475 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
5476 (ifnames, autoscan, autom4te): Since we don't only depend on
5477 configure.ac variables (such as VERSION etc.), but also on prefix
5478 and so forth, depend on Makefile, not configure.ac.
5479 Reported by Alexandre Duret-Lutz.
5480 * doc/autoconf.texi (Installation Directory Variables): Adjust.
5482 2002-09-05 Kevin Ryde <user42@zip.com.au>
5484 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
5485 doesn't seem to be confined to ia64, just say "some versions".
5487 2002-09-04 Akim Demaille <akim@epita.fr>
5489 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
5491 * Makefile.am (maintainer-clean-local): Remove.

5497 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
5500 2002-09-03 Akim Demaille <akim@epita.fr>
5502 * configure.ac: Bump to 2.53d.
5503 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
5504 as of today, on Automake's team suggestion.
5506 2002-09-03 Akim Demaille <akim@epita.fr>
5510 2002-09-02 Akim Demaille <akim@epita.fr>
5512 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
5514 * configure.ac: Disable SITE_MACRO_DIR.
5516 2002-09-02 Jim Meyering <meyering@lucent.com>
5518 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
5519 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
5520 Also, tweak grammar: s/make sure to/be sure to/.
5522 2002-09-02 Paul Eggert <eggert@twinsun.com>
5524 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
5525 directory names are generally preferable to physical names.
5527 2002-09-02 Akim Demaille <akim@epita.fr>
5529 * lib/Autom4te/General.pm (&update_file): s/die/error/.
5530 Reported by Raja R. Harinath.
5531 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
5532 * bin/autoupdate.in: Use error instead of die.
5534 2002-09-01 Paul Eggert <eggert@twinsun.com>
5536 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
5537 ordinary shell concatenation rather than echo+tr+sed command that
5538 runs afoul of a long-line-related sed bug in Solaris 8.
5540 * bin/autoheader.in (parse_args): --warning -> --warnings.
5542 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
5543 stdout, as traditional "ls" does.
5544 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
5545 _AC_COMPILER_EXEEXT_O): Likewise.
5546 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
5548 * bin/autoconf.as: Add --prepend-include option. This patch was
5549 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
5550 but bin/autoconf.in is generated automatically from bin/autoconf.as.
5552 * bin/autoconf.in, configure: Regenerate.
5554 * doc/autoconf.texi (Special Shell Variables): Mention
5555 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
5557 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
5558 MAILPATH and set PS1, PS2, PS4 to default values, to work
5559 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
5560 For LC_ALL etc, first try to set to "C" as POSIX requires and as
5561 the Autoconf documentation specifies; fall back to "unset" only if
5562 this fails. Use a shell for-loop for this rather than an m4 loop,
5563 to shorten the output script.
5565 2002-08-30 Paul Eggert <eggert@twinsun.com>
5567 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
5568 1003.1-2001's requirements for CDPATH. Give a simpler workaround
5569 for the CDPATH problem. Document PWD.
5570 (Limitations of Builtins): Document the problem that "cd $foo" and
5571 "ls $foo" may refer to different directories in shells conforming
5572 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
5573 example, since the old example is now out of date.
5575 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
5576 FOO" and "ls FOO" talk about different directories; this catches
5577 problems when POSIX 1003.1-2001 "cd" fails due to symlink
5580 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
5581 of rolling our own unset.
5582 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
5583 in practice we needn't worry about CDPATH if unset doesn't work.
5585 * Makefile.in, aclocal.m4, bin/Makefile.in,
5586 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
5587 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,

5589 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
5590 tests/Makefile.in: Regenerate with Automake 1.6.3.
5592 * config/config.guess, config/config.sub, config/mkinstalldirs:
5595 * configure: Regenerate with self.

5607 2002-08-29 Akim Demaille <akim@epita.fr>
5609 * lib/Autom4te/General.pm (&xqx): New.
5610 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
5611 hand, which is not portable.
5613 * bin/autom4te.in: Use them.
5614 Use &error instead of die.
5615 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
5618 2002-08-17 Paul Eggert <eggert@twinsun.com>
5620 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
5621 default list of compilers to try, since it was long ago superseded
5622 by the ksh fc builtin. Suggested by Steven G. Johnson.
5624 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
5626 * doc/autoconf.texi (Invoking autom4te): End the option table,
5627 fixing a bug introduced by the previous patch.
5628 (Limitations of Make): Add a 'target lookup' subentry in the
5629 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
5631 2002-07-29 Mark D. Roth <roth@feep.net>
5633 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
5634 options and use $AUTOM4TE_PATH.
5635 * doc/autoconf.texi: Remove documentation of autom4te
5636 --include-envvar and --site-macro-subdir options and document
5637 use of $AUTOM4TE_PATH.
5638 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
5639 arguments from each language section.
5641 2002-07-29 Paul Eggert <eggert@twinsun.com>
5643 * doc/install.texi: Include copyright symbol in copyright notice.
5645 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
5647 (AM_MAKEINFOFLAGS): New macro.
5648 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
5649 * Makefile.am (INSTALL): Use the new macros.
5650 Use -o rather than --output, since "missing" does not grok --output.
5652 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
5654 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
5655 comments do not always work. Never trust the exit status of
5658 2002-07-24 Kevin Ryde <user42@zip.com.au>
5660 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
5661 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
5663 2002-07-23 Paul Eggert <eggert@twinsun.com>
5665 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
5666 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
5667 apparently treats PATH="nonexistent" as if it contained ".".
5668 Bug reported by Stefan `Sec' Zehl.
5670 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
5672 * doc/autoconf.texi (Limitations of Make): Mention the special

5829 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
5831 * bin/autom4te.in ($cache): Don't define using `$me', the name
5832 of the cache should not depend on the name under which autom4te

5868 ac_config_libobj_dir.
5869 (AC_CONFIG_LIBOBJ_DIR): New.
5870 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
5871 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
5872 Use ac_config_libobj_dir to find the replacement files.
5873 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
5874 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
5875 (AC_REPLACE_FNMATCH_GNU): these.
5876 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
5877 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
5878 * tests/mktests.sh (ac_exclude_list): Don't check
5879 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
5881 2002-06-06 Paul Eggert <eggert@twinsun.com>
5883 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
5886 * doc/autoconf.texi (Configuration Links): Likewise.
5887 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
5889 2002-06-05 Paul Eggert <eggert@twinsun.com>
5891 * config/config.guess, config/config.sub, config/texinfo.tex:
5892 Update from masters.
5894 2002-05-29 Paul Eggert <eggert@twinsun.com>
5896 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
5897 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
5898 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

5917 * NEWS, doc/autoconf.texi (Particular Types): Document it.
5918 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
5919 instead of AC_MBSTATE_T, which never existed.
5921 2002-05-23 Akim Demaille <akim@epita.fr>
5923 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
5924 version of Autoconf that is discussed.
5926 2002-05-22 Paul Eggert <eggert@twinsun.com>
5928 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
5929 from the default list of compilers to try. Suggested by
5931 * NEWS: Document the above.
5932 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
5934 2002-05-17 Paul Eggert <eggert@twinsun.com>
5936 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
5937 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
5938 This improves on an earlier suggestion by H. Peter Anvin.
5940 2002-05-16 Paul Eggert <eggert@twinsun.com>
5942 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
5943 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
5944 Both macros now accept an optional source-dir arg.
5945 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
5947 * NEWS: Document this.
5948 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
5950 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
5951 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
5952 not for GNU extensions; this undoes part of the 2000-11-03 change,
5953 reverting to 2.13-compatible behavior.
5954 Add new optional argument DIR.
5955 (AC_FUNC_FNMATCH_GNU): New macro.
5957 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
5959 2002-05-08 Paul Eggert <eggert@twinsun.com>
5961 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
5962 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
5963 and it causes a 'test' syntax error if it fails.
5964 Bug reported by Stephen Gildea.
5966 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
5967 If prototypes are supported, use them to check this at compile-time,
5968 instead of trying to check it at run-time. If we must do a run-time
5969 check, assume that setvbuf is standard when cross-compiling, as
5970 nonstandard setvbuf occurs only on ancient and unlikely hosts.
5971 Bug reported by Paul D. Smith.
5973 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
5974 argument specifying location of getloadavg.c. This removes a
5975 FIXME. This idea was taken from Jim Meyering's implementation in
5977 * doc/autoconf.texi (Particular Functions): Document this.
5978 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
5979 that's what the code does; this fixes a bug reported by
5982 2002-05-03 Akim Demaille <akim@epita.fr>
5984 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
5985 autopoint instead of gettextize.
5986 ($uses_alocal): Rename as...
5987 ($uses_aclocal): this.
5988 * doc/autoconf.texi (autoreconf Invocation): Adjust.
5989 Suggested by Bruno Haible.
5991 2002-05-03 Akim Demaille <akim@epita.fr>
5993 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
5995 2002-04-29 Paul Eggert <eggert@twinsun.com>
5997 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
5998 files to be 1 second older; just set them to be the same time.
5999 Also, sleep 1 second after the first aclocal, to work around
6000 problems with sub-second time stamps on the input files.
6002 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
6004 * doc/autoconf.texi: Mention "set -e -x" lossage
6005 under node "Limitations of Builtins".
6007 2002-04-29 Akim Demaille <akim@epita.fr>
6009 * doc/install.texi: Better wording for setting variables when
6011 From Christian Cornelssen.
6013 2002-04-29 Akim Demaille <akim@epita.fr>
6015 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
6016 of lack of $LINENO support, then the test will compare the $LINENO
6017 in testsuite vs. the lineno in the test file. This is wrong, of
6019 Be sure to protect it.
6020 Reported by Patrick Welche.
6022 2002-04-25 Akim Demaille <akim@epita.fr>
6024 * doc/autoconf.texi (Obsolete Macros): Typo.
6025 Reported by Vladimir Volovich.
6027 2002-04-25 Akim Demaille <akim@epita.fr>
6029 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
6030 than some of the input files, hence, on the second run of aclocal,
6031 if some of its input are younger, make them older.
6032 Suggested by Paul Eggert.
6034 2002-04-25 Akim Demaille <akim@epita.fr>
6036 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
6037 Thanks to Paul Eggert.
6039 2002-04-25 Akim Demaille <akim@epita.fr>
6041 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
6042 and ac_subst_vars be sh variables containing the list of
6043 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
6045 (_AC_INIT_PREPARE): Use them to log them.
6046 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
6047 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
6048 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
6049 _AC_SUBST_FILES and _AC_SUBST_VARS.
6050 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
6052 2002-04-24 Akim Demaille <akim@epita.fr>
6054 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
6055 autoheader, so that automake does not complain about a missing
6056 config.h.in that was to be created.
6058 2002-04-23 Akim Demaille <akim@epita.fr>
6060 * bin/autoheader.in (parse_args): --warning takes an argument.
6063 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
6065 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
6066 and bb.out when cleaning up.

6110 Minor spelling and grammar fixes.
6112 * doc/autoconf.texi: Follow the outline suggested in the GNU
6113 Sample Texts sections of the Texinfo 4.2 manual. Most
6114 importantly, this makes sure that the copyright notices appear in
6115 all output formats. You probably need Texinfo 4.2 to generate

6140 that is not portable to Zsh.
6142 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
6144 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
6145 from aclocal.m4 too.
6147 2002-04-12 Akim Demaille <akim@epita.fr>
6149 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
6151 2002-04-10 Akim Demaille <akim@epita.fr>
6153 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
6154 workaround for ${1+"$@"}.
6155 * doc/autoconf.texi (Shell Substitutions): Explain it.
6156 From Oliver Kiddle and Peter Stephenson.
6158 Have M4sh perform minimal shell sanitizing.
6160 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
6162 (_AS_PREPARE): this new macro.
6164 (AS_INIT): Invoke AS_SHELL_SANITIZE.
6165 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
6167 Adjust Autoconf and Autotest.
6169 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
6170 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
6171 * lib/autotest/general.m4 (AT_INIT): Likewise.
6172 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
6173 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
6176 Use this M4sh to generate Autoconf's shell scripts.
6178 * tests/wrapsh.as: New, precursor of wrapsh.in.
6179 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
6180 on Autotest and M4sh.
6181 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
6182 (wrapsh.in): New target.
6183 * bin/autoconf.as: New, precursor of autoconf.in.
6184 (autoconf.in): New target.

6193 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
6194 ac_top_builddir when setting ac_abs_top_builddir.
6196 2002-04-06 Kevin Ryde <user42@zip.com.au>
6198 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
6199 (Portable Shell): Cross reference to Systemology.
6201 2002-04-05 Akim Demaille <akim@epita.fr>
6203 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
6204 directories when descending in a SUBDIRS.
6205 Reported by Ezra Peisach.
6207 2002-04-04 Andreas Schwab <schwab@suse.de>
6209 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
6210 contains no literal separators.
6212 2002-04-03 Akim Demaille <akim@epita.fr>
6214 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
6215 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
6216 Use dnl, not the KILL diversion.
6218 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
6219 (AC_CONFIG_LINKS): here.
6221 Don't use the KILL diversion, as it kills spurious output, which
6222 results in failures being hidden.
6223 Use m4_defn where appropriate.
6224 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
6225 after the second argument.
6227 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
6228 syntax, as it is provided by M4sugar.

6245 (_AC_COMPILER_OBJEXT): Use them.
6246 Fixes Debian #138666.
6248 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
6250 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
6252 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
6253 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
6254 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
6255 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.

6273 2002-03-27 Paul Eggert <eggert@twinsun.com>
6275 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
6276 (AS_SHELL_SANITIZE): Invoke it.
6277 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
6279 2002-03-26 Akim Demaille <akim@epita.fr>
6281 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.

6293 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
6295 * doc/autoconf.texi (Limitations of Make): Mention more issue
6296 about VPATH, overriding of macros in sub-makes, and handling of
6299 2002-03-21 Paul Eggert <eggert@twinsun.com>
6301 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
6302 problem with here-document buffer boundaries.
6304 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
6305 when reinvoking the shell, to work around problems with installers
6306 who put strange things like "cd" commands in their environments.
6308 2002-03-19 Akim Demaille <akim@epita.fr>

6330 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
6331 (Limitations of Usual Tools): Add mkdir section.
6333 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
6334 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
6335 back on AS_DIRNAME to compute prefixes otherwise; this is
6336 roughly what mkinstalldirs does. That way, we need not have
6337 our own filename disassembler. The old disassembler did not
6338 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
6340 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
6341 Create at_test_all by a series of assignments,
6342 not by a single assignment of a long string. The latter causes ksh
6343 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
6344 presumably because of a buffer overrun.
6346 2002-03-14 Paul Eggert <eggert@twinsun.com>
6348 * lib/autotest/general.m4 (at_times_skip):
6349 Renamed from at_times. Now a boolean.
6350 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
6351 says 'times: not found'.
6353 2002-03-14 Akim Demaille <akim@epita.fr>
6355 * bin/autoreconf.in (&study_gettextize): New.

6401 aliases the actual variables, and modifications of the former

6406 * bin/autom4te.in (&handle_m4): Protect us from corrupted file

6456 that it contains exactly the items, not an expression which
6457 evaluation is the current item.
6458 (m4_re_string, m4_re_word): Don't over quote them.
6460 2002-03-04 Akim Demaille <akim@epita.fr>
6462 Instead of having stacking `shift's evaluated at the end, let
6463 `foreach' loops immediately evaluate them.
6465 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
6466 $*. This is the n-th time I change my mind, but hopefully this is
6469 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
6471 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
6472 it was only a hack for m4_text_wrap.
6473 (m4_car2): Remove, replaced by...
6475 (_m4_foreach): Adjust.
6476 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use

6565 cross-compilers, too. This undoes some of the most recent change
6568 2002-02-05 Akim Demaille <akim@epita.fr>
6570 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

6596 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
6597 (M4sh): Rely on M4sugar.
6598 (Autotest, M4sh, M4sugar): Use frozen files.

6635 2002-01-28 Akim Demaille <akim@epita.fr>
6637 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
6638 AUTOTEST_PATH *after* it was set.
6639 Don't put `.' in the PATH: the user should be precise and `./' if
6640 needed. In addition, given that the test suite does some `cd', if
6641 `.' is in the path, the `tested programs' sections will report
6642 programs found in the test suite's directory, while during the
6643 tests (performed in their own directory), these programs are no
6644 longer visible. In other words, the results is confusing and

6715 * tests/Makefile.am (package.m4): New.
6716 EXTRA_DIST it since its a source.

6721 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
6722 and PACKAGE_BUGREPORT from here...
6723 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
6725 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
6726 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
6727 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
6728 * tests/tools.at (autoheader): Adjust.

6753 trailing files, don't apply `-rf' to files which might not be
6754 created by configure (core, core.*, and *.core), but just `rm -f'.
6755 Suggested by Jonathan Kamens.
6757 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

6794 Remove $filepath, useless.
6795 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@

6797 Split the input line on spaces and then look for tokens.
6798 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison

6859 $host' usage so people quit using `case $target' everywhere.
6861 2001-11-22 Akim Demaille <akim@epita.fr>
6863 * doc/autoconf.texi (Installation Directory Variables): Englishoes
6864 spotted by Jim Meyering.
6866 2001-11-16 Paul Eggert <eggert@twinsun.com>
6868 This patch implements a `long double' suggestion by Oliver Kiddle.
6870 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
6871 static, to catch errors if the value isn't known at compile-time
6872 and the compiler supports dynamic arrays. Change its name from
6873 `_array_' to `test_array' to avoid potential name clashes.
6874 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
6875 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
6876 better than double. Catch a bug in GCC 2.95.2 x86.
6877 * doc/autoconf.texi (C Compiler): Document the above.
6880 2001-11-13 Akim Demaille <akim@epita.fr>
6882 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by

6889 group, go back to the initial directory, not to at_suite_dir.

6893 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
6894 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
6895 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
6897 (AT_CHECK_CONFIGURE): Use absolute paths.
6898 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
6899 The problem is still the old one: there is no means in M4 (that I
6900 know about) to create a defining macro, because there is no means
6901 to create `$1' etc., therefore, the defining macro ``swallows''
6902 all the arguments meant to the defined macro.
6904 2001-11-13 Akim Demaille <akim@epita.fr>
6906 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
6907 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
6909 * tests/aclocal.m4: Remove, as it is no longer used.
6911 2001-11-13 Akim Demaille <akim@epita.fr>

6929 2001-11-13 Akim Demaille <akim@epita.fr>
6931 * tests/tools.at: Use absolute paths, since we are no longer run
6934 2001-11-13 Akim Demaille <akim@epita.fr>
6936 Now that tests are running in their own private dir, there is no
6937 need to list the files to remove at the end of tests groups.
6939 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
6940 (AT_data_files, at_data_files): Remove.
6941 (AT_CLEANUP, AT_DATA): Simplify.
6943 Remove the group dir if !debug && !failed.
6944 * tests/atspecific.m4: Adjust.
6946 2001-11-13 Akim Demaille <akim@epita.fr>
6948 Start a new layout for Autotest: `testsuite' creates
6949 `testsuite.dir' in which the at-check-line etc. files are to be
6950 found, and `testsuite.dir/003' where the test group 3 is run.
6952 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
6953 at_check_line_file, at_format, at_test_normalized, at_group_dir
6955 Create the directories.
6956 Use absolute paths for at- files.

6972 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
6973 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines

6991 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
6994 2001-11-12 Akim Demaille <akim@epita.fr>
6996 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
6997 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
6998 definition used by Automake where LEX is +/- "${missing} lex" and
6999 `missing' itself contains variables.
7001 2001-11-12 Akim Demaille <akim@epita.fr>
7003 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
7004 Now that M4sh pushes BODY, the comments were output at the end of
7007 2001-11-08 Akim Demaille <akim@epita.fr>
7009 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
7010 that we can trace macros from aclocal.m4.
7011 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
7012 obsoleted, and redirect to the former anyway.
7013 Reported by Ralf Corsepius.
7015 2001-11-08 Akim Demaille <akim@epita.fr>
7017 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be

7020 instead of successive calls to autoconf.
7021 Add a nonexistent subdirectory to exercise the patch above.
7022 Reported by Ralf Corsepius.
7024 2001-11-08 Kevin Ryde <user42@zip.com.au>
7026 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
7027 doesn't accept .S files.

7065 * lib/Autom4te/General.pm: (&catfile, &canonfile)
7066 (&file_name_is_absolute): New, wrappers around routines from
7068 Use and export them.
7069 (&find_configure_ac): Optionally take a directory where to look at.
7070 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of

7074 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.

7080 (@export_forward_subs): New.
7081 Add basename, dirname, and fileparse.
7083 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
7084 Don't look for aclocal flags if we already know aclocal is not
7086 Move aclocal.m4t only if it exists.
7087 Reported by Ezra Peisach.
7089 2001-11-03 Akim Demaille <akim@epita.fr>
7091 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
7092 passed on command line, defaulting to ./configure.ac if present.
7093 (&maybe_autoreconf, File::Find): Remove, unused.
7094 (&autoreconf): If autoconf is not used, don't try to trace.
7096 2001-11-02 Akim Demaille <akim@epita.fr>
7098 * configure.ac: Bump to 2.52g.
7100 2001-11-02 Akim Demaille <akim@epita.fr>

7113 Don't run aclocal when aclocal.m4 is not from aclocal.
7115 Don't run libtoolize and gettextize if --install is not given.
7117 2001-11-01 Paul Eggert <eggert@twinsun.com>
7119 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
7120 be invoked before _AS_LINENO_PREPARE.
7121 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
7122 than character ranges.
7124 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
7125 invoking AS_BASENAME. Set the locale variables to 'C' if
7126 possible, as POSIX requires this to get the traditional
7128 * doc/autoconf.texi (Special Shell Variables): Describe the above.
7130 2001-10-31 Paul Eggert <eggert@twinsun.com>
7132 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
7133 with {}, as that triggers a bug in Bash 2.05.
7135 (_AS_LINENO_PREPARE): Use Sed rather than
7136 Awk. Fix the sed prepass to work even if there are multiple
7137 instances of $LINENO on the same line. Do not substitute for
7138 other variables like $LINENOT. Do not check file dates; such a
7139 check is unreliable on sufficiently fast machines, and removing
7140 the check makes the code simpler and more reliable. Check for
7141 output and chmod failures.
7143 * doc/autoconf.texi (Special Shell Variables): Document
7146 2001-10-31 Akim Demaille <akim@epita.fr>

7158 2001-10-26 Paul Eggert <eggert@twinsun.com>
7160 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
7161 lib/Autom4te/Struct.pm:
7162 Require Perl 5.005_03 instead of just 5.005, as some tests fail
7165 * doc/autoconf.texi (Special Shell Variables): Document some
7166 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
7168 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
7169 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
7170 eval $LINENO is not portable in practice.
7172 2001-10-24 Akim Demaille <akim@epita.fr>
7174 * lib/Autom4te/General.pm (backname): New.

7186 2001-10-22 Paul Eggert <eggert@twinsun.com>
7188 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
7189 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
7190 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
7191 POSIX decided to standardize on the int flavor of strerror_r.
7192 Always do char* test, as there's no reason not to.
7193 Assign to a char* var, to catch strerror_r that returns int*.
7195 * doc/autoconf.texi (Particular Functions):
7196 Document the above changes. Also, document the fact that
7197 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
7199 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
7201 2001-10-20 Akim Demaille <akim@epita.fr>
7203 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

7217 * doc/autoconf.texi: Adjust.
7219 2001-10-20 Akim Demaille <akim@epita.fr>
7221 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
7223 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
7224 `intl' is already present, as it refuses unless --force.
7225 (&parse_args): Use -I, --include instead of the old Autoconf
7227 ($localdir, $autoconf_dir): Remove.
7229 (&maybe_autoreconf): New, to preserve $_ for File::Find.
7231 2001-10-19 Jens Petersen <petersen@redhat.com>
7233 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

7238 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated

7261 (AS_BASENAME_EXPR): New macro.
7262 (AS_BASENAME_SED): Do not assume GNU sed semantics.
7263 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
7264 and fall back on 'sed' only if the other two fail. This makes
7265 AS_BASENAME act more like AS_DIRNAME.
7266 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
7267 contains white space.
7268 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
7269 Use AS_DIRNAME, since I think it's now DOS-friendly.
7270 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
7271 Allow "dirname //FOO" to return either / or //, as POSIX allows
7274 2001-10-10 Akim Demaille <akim@epita.fr>

7322 bother with $force since...

7396 (AT_INIT): Replace AC_PLAIN_SCRIPT with AS_INIT invocation,
7397 include handle the m4_pattern_*, no longer push the
7398 BODY diversion nor set the /bin/sh line, AS_INIT does it.
7399 * lib/autotest/general.m4 (AT_INIT): Likewise.
7400 * tests/base.at: Adjust the tests to use AS_INIT.

7411 shell does not support LINENO, and if CONFIG_SHELL is unset or
7412 empty, and if we can find a shell that does support LINENO,
7413 then set CONFIG_SHELL to that shell and then re-execute
7414 ourselves with CONFIG_SHELL.
7416 2001-10-05 Paul Eggert <eggert@twinsun.com>
7418 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
7419 doesn't exist. Remove *.tmp, as a .tmp file is created during the
7420 build of $(TESTSUITE).

7461 compatibility with POSIX shells.

7538 * doc/autoconf.texi (autoconf Invocation): Fix the example:
7539 AC_TRY_RUN is about compilation, not shell commands.
7540 (Test Programs): AC_TRY_RUN works as used to be advertised.

7726 * doc/autoconf.texi (Common Shell Constructs): New node,
7727 documenting AS_DIRNAME.
7728 (Limitations of Usual Tools): Refer to it when discussing dirname.
7729 Also, update discussion of POSIX standard to reflect latest draft.

7732 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
7734 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
7735 Do not pass a first argument with leading '-'
7736 to expr, by parenthesizing initial integers that might be negative.
7738 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
7739 now merely checks whether it is an error to pass an argument
7742 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
7743 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
7744 whether it is a (compile-time) error to pass an argument to
7745 getpgrp. This simpler test supports the revised documentation,
7746 and is all that AC_FUNC_GETPGRP's users really need.

7762 Add test for AS_BASENAME.
7763 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
7764 added test. It now correctly handles /1/2/3/, returning '3' not ''.
7765 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
7766 * tests/base.at: Fixed the expected responses. The old ones were
7768 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
7769 the documentation claims it should (and how it behaved in 2.13).
7771 2001-09-18 Akim Demaille <akim@epita.fr>
7773 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
7774 the AC_CONFIG_COMMANDS invocation.
7775 This also solves the name clash problems.
7776 Don't set the package's ID.

7778 No longer to be shipped.
7779 (version.in): Remove.

7784 the only optional argument is the name of the test suite.
7785 Expect `package.m4' to define the package signature.
7786 * lib/autom4te.in (Autotest): Add `package.m4?'.
7787 * tests/Makefile.am (package.m4): New.

7807 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
7808 Always include <stdio.h> and <stdlib.h>. Evaluate
7809 the expression in an extra function before these includes. Call
7810 fprintf "%d" only after ensuring the argument is of type 'int'.
7811 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
7813 2001-09-17 Paul Eggert <eggert@twinsun.com>
7815 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
7816 or CFLAGS=-O5. In that case, the linker has a relaxed view of
7817 fatal errors, and AC_CHECK_LIB causes it to include libraries even
7818 when they don't exist.
7820 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
7821 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
7824 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
7825 version with the version used by fileutils 4.1, except use
7826 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
7829 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.

7869 2001-09-13 Akim Demaille <akim@epita.fr>
7871 * lib/autotest/general.m4 (AT_INIT): Create and remove
7872 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
7873 test suites can cohabit.
7875 2001-09-13 Akim Demaille <akim@epita.fr>
7877 * tests/mktests.sh: Don't output banners for empty test files.
7879 2001-09-13 Akim Demaille <akim@epita.fr>

7983 2001-09-05 Akim Demaille <akim@epita.fr>
7985 Be ready to handle filenames as stupid as `dnl.at', for if even
7986 the maintainer is dumb enough to do that...
7988 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
7989 excellence in M4 quotation: consider `__file__' is active.
7991 And BTW, when invoking m4, pass the --include in the right order:

8022 New, extracted from main.
8023 Use IO::File wherever possible.

8057 (testsuite Scripts): There is no such thing as `atconfig.in'.
8058 And actually one diagram is missing: test suite runtime.
8060 2001-08-31 Akim Demaille <akim@epita.fr>
8062 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

8140 Map --localdir, --autoconf-dir onto it.
8141 Forward autom4te's options instead of interpreting them.
8142 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
8143 There is no such envvar since the inception of autom4te.cfg.
8144 * bin/autom4te.in (&parse_args): Uniquify `@include'.

8165 * lib/Autom4te/General.pm (&find_peer): Remove.
8166 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

8168 * man/Makefile.am: Let help2man rely on PATH instead of trying to
8169 find the executables for it.
8170 * tests/Makefile.am: Major cleanup. Too lazy to document...
8171 * tests/atlocal.in: Remove all the obscure envvar manipulations.
8173 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
8174 indeed related to running the test suite, while passing
8175 --autoconf-dir and others is related to running non installed
8176 Autoconf executables. So don't do that, leave it to...
8177 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
8178 * tests/autoscan: New.
8179 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

8196 Suggested by Paul Eggert.
8198 2001-08-29 Akim Demaille <akim@epita.fr>
8200 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
8201 download in a tmp dir.
8203 2001-08-29 Akim Demaille <akim@epita.fr>
8205 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

8587 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
8588 `$0.log' as for projects where testsuite is in src, we'd have
8589 testsuite.log created in src.
8591 2001-08-17 Akim Demaille <akim@epita.fr>
8593 * bin/autom4te.in (&parse_args): Recognize --normalize.

8605 * doc/autoconf.texi: Work around Texinfo buglets.
8606 (Transformation Rules): One example is enough, users are expected
8607 to have their brains on. And BTW, use DESTDIR.
8608 (dvar): New macro. Use it.

8664 * tests/Makefile.am: Use a clean-local rule to remove
8665 autom4te.cache (it's a directory, not a file.
8666 * Makefile.am: Ditto (but maintainer-clean-local).
8668 2001-08-15 Akim Demaille <akim@epita.fr>

8677 2001-08-15 Akim Demaille <akim@epita.fr>
8679 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:

8742 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
8744 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
8745 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
8746 * doc/autoconf.texi (C Compiler Characteristics): Update

8752 magic values from an object file when cross-compiling.
8753 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
8755 2001-08-10 Akim Demaille <akim@epita.fr>
8757 * bin/autom4te.in (&handle_output): Don't use `grep' with side
8759 Suggested by Russ Allbery.
8761 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
8763 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
8764 current $prefix to the sub-configures.
8766 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
8768 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable

8775 2001-08-07 Akim Demaille <akim@epita.fr>
8777 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
8779 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
8780 No need to remove the files before and after the each test, before
8781 each test and at the end of the suite is enough.
8782 Display only the children `times', not the shell's.
8783 If the test failed or was skipped, at-times is not available.
8785 2001-08-07 Akim Demaille <akim@epita.fr>
8787 Always produce testsuite.log, including when there are no
8788 failures. This helps getting information on skipped tests, and
8789 duration of the tests. Err, implement the latter btw.
8791 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
8792 Dump information on the first run of each test.
8793 (AT_CLEANUP): Create `at-times' containing the duration of the
8796 2001-08-07 Akim Demaille <akim@epita.fr>
8798 The use of `dumpstat' revealed that `len' was used although it
8799 should not. m4_text_wrap was using it, but in the Autoconf world
8800 where it is legal. Hence (i) test M4sh in its own world, not
8801 Autoconf's, and (ii), ahem, fix the bug :)
8803 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
8804 does not like `' instead of [].
8805 (AT_INIT): Forbid `^_?AT_'.
8806 And don't output such tokens.
8807 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
8808 `script.as', and `autom4te.cache'.
8809 Remove `empty' and `macro' which are no longer used.
8810 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
8811 * tests/m4sugar.at: Use it.
8812 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.

8831 2001-08-04 Akim Demaille <akim@epita.fr>
8833 Don't rely on M4sugar outputting the patterns in files, since we
8834 might process the output _without_ running m4, hence without these
8837 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
8838 * bin/autom4te.in (@Request::includes): Remove, unused.
8839 (@Request::source): Rename as...
8840 (@Request::input): this.
8841 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
8842 (&handle_output): Fetch the patterns from the traces.
8843 `$forbidden' and `$allowed' are constant: use m//o.
8844 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
8845 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
8847 2001-08-04 Akim Demaille <akim@epita.fr>
8849 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
8850 autoconf', i.e., in addition to caching traces, cache the output.
8852 * bin/autom4te.in (Request::cache): Rename as...
8853 (Request::id): this.
8854 ($cache, $icache, $tcache, $ocache): New.
8855 (&handle_m4): Save M4 output in the cache instead of $tmp.
8856 (&handle_output): Adjust.
8857 (&up_to_date_p): Check that the output cache is up to date too.
8858 (top level): Run `&handle_m4' iff force or the cache is invalid.
