12012-01-15 Jim Meyering <meyering@redhat.com> 2 3 getopt: refine syntax of previous change 4 * lib/Autom4te/General.pm (getopt): Use a more concise test. 5 62011-01-15 Stefano Lattarini <stefano.lattarini@gmail.com> 7 8 getopt: remove hack for special handling of "-" argument 9 10 Older versions of Getopt::Long acted bogusly and died when they 11 where configured with the 'bundling' flag and an argument '-' was 12 seen on the command line they were parsing. That is no longer 13 the case though, and has not been for quite a long time: the bug 14 is no longer present in the 5.6.2 version of perl and the 2.25 15 version of Getopt::Long (and today, the latest versions of perl 16 and Getopt::Long are respectively 5.14.2 and 2.38). The obsolete 17 workaround for that Getopt::Long bug can thus be removed from our 18 'getopt' function. 19 20 It is also worth noting that such a workaround was quite buggy 21 and brittle itself; for example, a command like this: 22 "autom4te --output -" 23 would have caused the incorrect diagnostic: 24 "autom4te: option `--output' requires an argument" 25 Much worse, a command like this: 26 "autom4te --language=autoconf --output - configure.ac" 27 would have caused the standard input of autom4te to be processed 28 and copied into the 'configure.ac' file, deleting its pre-existing 29 content! Surely not what a user would have expected. 30 31 After this change, a command like this: 32 autom4te --language=autoconf --output - - <configure.ac >out 33 works as expected, processing the input from 'configure.ac' and 34 writing it to the 'out' file. 35 36 * lib/Autom4te/General.pm (use): Require perl version 5.6.2. 37 (getopt): Remove the old workaround. 38 392012-01-15 Jim Meyering <meyering@redhat.com> 40 41 avoid new warning about undefined $ARGV[0] 42 * lib/Autom4te/General.pm (getopt): Avoid warning induced by 43 yesterday's change: $ARGV[0] may not be defined, e.g., when 44 invoked via autoreconf. 45 462011-01-14 Stefano Lattarini <stefano.lattarini@gmail.com> 47 48 getopt: fix diagnostic for missing mandatory option argument 49 Before this change, an incorrect command line usage: 50 "autom4te --output" 51 triggered broken diagnostic like: 52 "autom4te: unrecognized option `--output'" 53 instead of the expected and correct: 54 "autom4te: option `--output' requires an argument" 55 * lib/Autom4te/General.pm (getopt): Give correct diagnostic in 56 case of usage errors due to missing arguments for options for 57 which they are mandatory. Code basically copied from automake's 58 'parse_arguments' private subroutine. 59 602012-01-05 Paul Eggert <eggert@cs.ucla.edu> 61 62 doc: mention Bash 2.03 bug with backslash-newline 63 * doc/autoconf.texi (Invoking the Shell): New section. 64 (Backslash-Newline-Empty): Rename from Backslash-Newline-Newline. 65 Mention problem with Bash 2.03. 66 67 doc: clarify sed buffer limit 68 * doc/autoconf.texi (Limitations of Usual Tools): 69 That 4000-byte limit applies to output and internal buffers, too. 70 712012-01-03 Paul Eggert <eggert@cs.ucla.edu> 72 73 maint: update copyright year 74 All files changed to add 2012, via 'make update-copyright'. 75 76 maint: resync upstream files 77 * ChangeLog, GNUmakefile, build-aux/announce-gen: 78 * build-aux/config.guess, build-aux/config.sub, build-aux/gendocs.sh: 79 * build-aux/git-version-gen, build-aux/move-if-change: 80 * build-aux/texinfo.tex, build-aux/update-copyright: 81 * build-aux/vc-list-files, doc/fdl.texi, doc/gendocs_template: 82 * doc/standards.texi, lib/Autom4te/XFile.pm, m4/autobuild.m4: 83 Regenerated by 'make fetch'. 84 852012-01-02 Paul Eggert <eggert@cs.ucla.edu> 86 87 autoconf: remove " -link" and ")" from xlf output 88 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): 89 Also remove " -link" and trailing ")" from xlf output. 90 Problem and fix reported by Thomas Jahns in 91 <http://lists.gnu.org/archive/html/bug-autoconf/2012-01/msg00000.html>. 92 932011-12-26 Stefano Lattarini <stefano.lattarini@gmail.com> 94 95 configure: will re-execute with $CONFIG_SHELL, if it's set 96 * lib/m4sugar/general.m4 (_AS_DETECT_BETTER_SHELL): Define the macro 97 `_AS_FORCE_REEXEC_WITH_CONFIG_SHELL' to `yes', so that the code in 98 `_AS_DETECT_BETTER_SHELL' will cause autoconf-generated configure 99 scripts to always re-execute themselves with $CONFIG_SHELL, if it's 100 set in the environment. 101 * doc/autoconf.texi (config.status Invocation): Update. 102 * doc/install.texi (Defining Variables): Likewise. 103 * NEWS: Likewise. 104 * tests/m4sh.at: Add tests for the new semantics in ... 105 (Configure re-execs self with CONFIG_SHELL): ... this new 106 test group. 107 1082011-12-26 Stefano Lattarini <stefano.lattarini@gmail.com> 109 110 m4sh: allow forced re-execution with $CONFIG_SHELL, if it's set 111 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): If the m4sh client 112 has defined the macro `_AS_FORCE_REEXEC_WITH_CONFIG_SHELL' to 113 "yes", emit code to always re-execute the current script with 114 $CONFIG_SHELL, if that's set. 115 * tests/m4sh.at: Add tests for the new and old semantics, in ... 116 (Re-exec with CONFIG_SHELL, Forced re-exec with CONFIG_SHELL): ... 117 these new test groups. 118 1192011-12-26 Stefano Lattarini <stefano.lattarini@gmail.com> 120 121 m4sh: refactor _AS_DETECT_BETTER_SHELL, for future changes 122 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Move code to 123 handle the re-execution of the shell ... 124 (_AS_REEXEC_WITH_SHELL): ... in this new macro. 125 1262011-12-24 Stefano Lattarini <stefano.lattarini@gmail.com> 127 128 docs: issue with shell functions and here-documents on Solaris 129 * doc/autoconf.texi (Here-Documents): Using a command substitution 130 in a here-documents being fed to a shell function is unportable. 131 Problem revealed by the automake testsuite: 132 <http://lists.gnu.org/archive/html/automake-patches/2011-12/msg00149.html> 133 1342011-12-26 Paul Eggert <eggert@cs.ucla.edu> 135 136 AS_LN_S: fall back on 'cp -pR' (not 'cp -p') if 'ln -s' fails 137 This works better for symlinks to directories. 138 Problem reported by Eli Zaretskii via Werner Lemberg in 139 <http://lists.gnu.org/archive/html/bug-autoconf/2011-12/msg00006.html>. 140 * NEWS: 141 * doc/autoconf.texi (Particular Programs): Document this. 142 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Implement this. 143 1442011-12-07 Paul Eggert <eggert@cs.ucla.edu> 145 146 AC_LANG_BOOL_COMPILE_TRY(C): port to g++ with warnings 147 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use the 148 array as well as setting it, to pacify g++.

It's unwise to use GCC 268 that way, but apparently enough people do it nowadays that it's an 269 issue. These days nobody uses the old compilers that the old 270 tests reject, so we can't test this fix against them, but it's 271 more important to work with modern GCC (even when misused) than to 272 work with no-longer-used compilers.

Use the new 7842 functions. 7843 7844 Properly handle funny file names for headers in config.status. 7845 The test suite did not cover this bug because the code was not 7846 quoting properly the arguments of `rm -f' (which "fails" silently) 7847 as well as the arguments of `diff' (whose output was redirected to 7848 /dev/null so we couldn't see its error message). 7849 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the 7850 file names passed to `rm' and `diff'. 7851 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): 7852 Add a regression test. 7853 78542008-03-01 Benoit Sigoure <tsuna@lrde.epita.fr> 7855 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 7856 7857 Properly expand @configure_input@ in config.status. 7858 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_MAIN_LOOP): 7859 Escape the backslashes and ampersands in $configure_input before 7860 using it in the sed replacement string to expand @configure_input@. 7861 Report by Eric Blake and Patrick Welche. 7862 78632008-03-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 7864 7865 Ignore errors from ./run on w32. 7866 * tests/autotest.at (whitespace in absolute testdir): 7867 Ignore stderr for `./run' which fails to remove the 7868 busy test directory on w32. 7869 78702008-02-22 Eric Blake <ebb9@byu.net> 7871 7872 Improve documentation for writing autotest suites. 7873 * doc/autoconf.texi (Writing Testsuites) <AT_CHECK>: Mention that 7874 checks must live inside a test group. 7875 Reported by Christopher Hulbert. 7876 78772008-02-21 Eric Blake <ebb9@byu.net> 7878 7879 Sync git-version-gen from upstream. 7880 * build-aux/git-version-gen: Pull from gnulib. 7881 * configure.ac (AC_INIT): Adjust to new calling convention. 7882 78832008-02-12 Eric Blake <ebb9@byu.net> 7884 7885 Avoid trailing space in config.h with AC_DEFINE([var], []). 7886 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Explicitly mark empty 7887 defines with a comment. 7888 78892008-02-08 Eric Blake <ebb9@byu.net> 7890 7891 Fix texinfo typos in previous patch. 7892 * doc/autoconf.texi (Site Defaults): s/[{}]/@&/g. 7893 Reported by Ralf Wildenhues. 7894 7895 Describe a config.site that can be used for FHS compliance. 7896 * doc/autoconf.texi (Site Defaults): Fix typo.

This is safe because config.status 8247 code is not executed before the file is complete. Other write 8248 failures, be they inside config.status, or in sub shell/awk 8249 scripts spawned from configure or config.status, typically need 8250 earlier checking, as their results are used right afterwards. 8251 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail' 8252 before writing config.status, check afterwards. 8253 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE) 8254 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS): 8255 Set `ac_write_error' for write failures to config.status.

Tru64 4.0D awk 8274 even splits the input if $i, i>0, was never accessed in the script. 8275 8276 Revert 2007-10-17 change. 8277 * TODO: Multiline args in config files and headers mean something 8278 different and are not fixed, see 8279 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html> 8280 Report by Stepan Kasal. 8281 8282 * doc/autoconf.texi (Generic Programs): Fix typo. 8283 82842007-11-16 Stepan Kasal <kasal@ucw.cz> 8285 8286 AC_*_TOOL does not canonicalize the prefix 8287 * doc/autoconf.texi (Generic Programs): Do not say that 8288 the *_TOOL macros canonicalize, they simply use the `host_alias'. 8289 82902007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 8291 8292 Diagnose write errors in config.status instantiations. 8293 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE) 8294 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out 8295 on write errors. 8296 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): 8297 Extend test to also check for some write error failures, using... 8298 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro. 8299 Report by Bruno Haible. 8300 8301 Indentation fixups. 8302 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix 8303 indentation. 8304 (_AT_CHECK): Use less indentation, to save space. 8305 83062007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 8307 8308 Add witness macro for @top_build_prefix@ substitution. 8309 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro. 8310 (_AC_OUTPUT_FILE): Mention it here. 8311 83122007-11-15 Paolo Bonzini <bonzini@gnu.org> 8313 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 8314 8315 * lib/autotest/general.m4 (at_func_test): Remove. 8316 (AT_INIT): Pre-extract test groups into separate files. 8317 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test. 8318 Remove at-test-source files together with the $at_group_dir. 8319 * tests/autotest.at (Long test source lines): New test. 8320 83212007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 8322 8323 Shell functions and variables may share a namespace. 8324 * doc/autoconf.texi (Portable Shell): Mention Solaris sh 8325 limitation. 8326 83272007-11-14 Paul Eggert <eggert@cs.ucla.edu> 8328 8329 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match 8330 gnulib. 8331 83322007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 8333 8334 * lib/autoconf/status.m4: Fix a couple of comment typos. 8335 8336 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me. 8337 83382007-11-13 Jim Meyering <meyering@redhat.com> 8339 8340 Clean up the rule to create "expr". 8341 * tests/Makefile.am (expr): Don't redirect directly to target. 8342 Redirect just once, not for each echo statement. 8343 Use $@, not literal "expr". 8344 83452007-11-13 Paul Eggert <eggert@cs.ucla.edu> 8346 8347 Don't worry about preprocessor when testing long long. 8348 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html 8349 * doc/autoconf.texi (Preprocessor Arithmetic): New section. 8350 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): 8351 These no longer check for preprocessor flaws. 8352 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): 8353 Do not check for preprocessor flaws. 8354 83552007-11-13 Jim Meyering <meyering@redhat.com> 8356 8357 Adapt dependencies, now that a version change doesn't modify configure.ac 8358 * GNUmakefile: Remove "make clean" kludge. 8359 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not 8360 configure.ac. 8361 Don't redirect directly to target. 8362 Use $@, not literal "version.m4". 8363 83642007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 8365 8366 * doc/autoconf.texi (Making testsuite Scripts): Document 8367 ":;{" shorthand as in previous patch. 8368 83692007-11-12 Paul Eggert <eggert@cs.ucla.edu> 8370 8371 * doc/autoconf.texi (Limitations of Builtins): Document problem 8372 with { ... } a bit more clearly.

See: 10081 http://lists.gnu.org/archive/html/libtool-patches/2005-01/msg00157.html 10082 100832007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 10084 10085 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also 10086 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its 10087 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual 10088 substitution will still be done by the special code. 10089 Report by Jim Meyering. 10090 10091 * doc/autoconf.texi (File System Conventions): Mention that 10092 $PATH_SEPARATOR is for the build system only. 10093 Report by Keith Marshall. 10094 100952007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 10096 10097 * doc/autoconf.texi (Setting Output Variables): Mention that 10098 all non-NUL characters are ok in substituted values. 10099 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo. 10100 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of 10101 carriage return for $AWK, needed for BSD awk. 10102 * tests/torture.at (Substitute and define special characters): 10103 Test all 8 bit non-NUL characters. 10104 Report against Automake by Patrick Welche. 10105 101062007-01-15 Stepan Kasal <kasal@ucw.cz> 10107 10108 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed. 10109 101102007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 10111 10112 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe 10113 early on the reader side, drop stderr of the input to avoid 10114 `broken pipe' error output; this may happen even with shell 10115 builtin `echo' of some bash versions. Reports by Ian Macdonald 10116 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>. 10117 101182007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 10119 10120 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to 10121 separate items of `ac_user_opts', to avoid long lines. 10122 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust. 10123 101242007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 10125 10126 * doc/autoconf.texi: Fix some typos. 10127 101282007-01-05 Paul Eggert <eggert@cs.ucla.edu> 10129 10130 Fix some wording problems noted by Paolo Bonzini in: 10131 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html 10132 * doc/autoconf.texi (Signed Overflow Examples): Give more 10133 discussion about the allow_superuser_privileges example, 10134 and change it a bit to make things clearer. 10135 (Optimization and Wraparound): Clarify whether the compiler 10136 will generate an infinite loop for the example derived from 10137 Autoconf's mktime test. 10138 (Signed Overflow Advice): Say that -ftrapv is meant for debugging. 10139 Also, clarify unsigned multiplication overflow. 10140 101412007-01-04 Eric Blake <ebb9@byu.net> 10142 10143 * bin/Makefile.am (RELEASE_YEAR): New macro. 10144 (edit): Use it to supply correct copyright year to scripts. 10145 * bin/autoconf.as (version): Use it. 10146 * bin/autoheader.in ($version): Likewise. 10147 * bin/autom4te.in ($version): Likewise. 10148 * bin/autoreconf.in ($version): Likewise. 10149 * bin/autoscan.in ($version): Likewise. 10150 * bin/autoupdate.in ($version): Likewise. 10151 * bin/ifnames.in ($version): Likewise. 10152 101532007-01-02 Paul Eggert <eggert@cs.ucla.edu> 10154 10155 * doc/autoconf.texi (Integer Overflow): Revised based on today's 10156 feedback. The most important changes document what happens when 10157 you convert an out-of-range value to a signed integer type, and 10158 say that (sum < a) != (b < 0) reliably detects overflow when sum = 10159 a + b. 10160 10161 * doc/autoconf.texi (Integer Overflow): Greatly expand and 10162 rewrite, taking notions from the recent discussion on the gcc and 10163 autoconf mailing lists; please see 10164 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html 10165 and follow the many links. 10166 (Integer Overflow Basics, Signed Overflow Examples): 10167 (Optimization and Wraparound, Signed Overflow Advice): 10168 (Signed Integer Division): New sections. 10169 101702006-12-28 Steven G. Johnson <stevenj@alum.mit.edu> 10171 10172 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include 10173 preprocessor macro arguments in traced name. 10174 * doc/autoconf.texi (Defining symbols): Document longstanding 10175 support for AC_DEFINE-ing macros with arguments, and document 10176 behavior when the same variable has multiple AC_DEFINEs. 10177 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the 10178 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_ 10179 macros directly, giving much shorter and simpler code. 10180 101812006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change) 10182 10183 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a 10184 space before "$ac_configure_args" to prevent a 'config.status 10185 --recheck' failure if ac_configure_args doesn't contain a leading 10186 space. This works around a problem with the XEmacs configure.ac, 10187 which uses the (undocumented) ac_configure_args variable 10188 inconsistently with Autoconf. 10189 101902006-12-22 Paul Eggert <eggert@cs.ucla.edu> 10191 10192 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): 10193 Include <limits.h>, and use its INT_MAX to rewrite the 10194 j loop so that it does not overflow 'int'. Problem reported by 10195 Ralf Wildenhues in 10196 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>. 10197 Play it safe by shifting left by 1 rather than multiplying by 2, 10198 as GCC is less likely to optimize this away when the value 10199 is signed (when it assumes overflow leads to undefined behavior). 10200 Also, don't assume time_t uses two's complement. 10201 102022006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 10203 10204 * tests/torture.at (Substitute a 2000-byte string): Avoid using 10205 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh 10206 dumps core on it. Report by Tim Rice. 10207 102082006-12-18 Steven G. Johnson <stevenj@alum.mit.edu> 10209 10210 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about 10211 --disable-option-checking to --help output even when 10212 AC_PRESERVE_HELP_ORDER is not used. 10213 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or 10214 --with argument, rather than argument with [-.] replaced by 10215 underscores. 10216 * NEWS: Fix typo in previous change; the news was in the 10217 wrong section. 10218 102192006-12-18 Paul Eggert <eggert@cs.ucla.edu> 10220 10221 * NEWS: Warnings are now generated by default for unknown 10222 --enable-* and --with-* options. 10223 * doc/autoconf.texi (Option Checking): Renamed from 10224 (Configure Option Checking). Tighten up the wording a bit. 10225 (External Software, Package Options): Cross-reference to Option 10226 Checking, and use this to shorten our section. 10227 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n 10228 "$x" to test "x$foo" != x. 10229 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise. 10230 Don't warn if $enable_option_checking is "no". 10231 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize 10232 ac_unrecognized_opts to the empty string. 10233 Don't echo the unrecognized opts, as this might mishandle 10234 backslashes or leading -. 10235 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking 10236 usage next to the other --disable-FEATURE options in the 10237 help string. 10238 102392006-12-18 Steven G. Johnson <stevenj@alum.mit.edu> 10240 10241 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS): 10242 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF): 10243 Print warning for unrecognized --with and --enable options 10244 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings. 10245 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS): 10246 Disable option checking when subdirs are configured. 10247 (AC_OUTPUT): If warnings are enabled, print warning about 10248 unrecognized --with and --enable options at the end of 10249 the configure output (as well as at the beginning). 10250 * doc/autoconf.texi (Option Checking): New node. 10251 Document new option warning functionality. 10252 102532006-12-16 Eric Blake <ebb9@byu.net> 10254 10255 * configure.ac (AC_INIT): Bump version, since 2.61a is released. 10256 * NEWS: Start news for current version. 10257 102582006-12-15 Paul Eggert <eggert@cs.ucla.edu> 10259 10260 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): 10261 Define HAVE_GETMNTENT to 1, not to the empty string. 10262 Problem originally reported by Jochen Friedrich in 10263 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>. 10264 10265 This change prompted by a problem report by Andrey Simonenko in 10266 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>. 10267 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for 10268 object-like macros only, in the traditional portable character 10269 set. 10270 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): 10271 Warn about attempts to define things that are not identifiers. 10272 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid 10273 awful hack that AC_DEFINEd macro names containing parentheses. 10274 102752006-12-12 Paul Eggert <eggert@cs.ucla.edu> 10276 10277 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was 10278 too drastic, even if Texinfo in theory requires it for info mode. 10279 10280 (config.status Invocation): Renamed back from Recreating a 10281 Configuration). 10282 (Obsolete config.status Use): Renamed back from Obsolete Recreation. 10283 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2. 10284 102852006-12-11 Paul Eggert <eggert@cs.ucla.edu> 10286 10287 * NEWS: Version 2.61a. 10288 102892006-12-11 Paul Eggert <eggert@cs.ucla.edu> 10290 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 10291 10292 * NEWS: Document changes with echo and printf, and the lack 10293 of limits on the total size of multi-line values of substituted 10294 variables, and the AC_FUNC_FSEEKO fix. 10295 102962006-12-10 Paul Eggert <eggert@cs.ucla.edu> 10297 10298 * doc/autoconf.texi (Writing Autoconf Input): Renamed from 10299 Writing configure.ac. 10300 (Autoconf Input Layout): Renamed from configure.ac Layout. 10301 (Recreating a Configuration): Renamed from config.status Invocation. 10302 (Obsolete Recreation): Renamed from Obsolete config.status Use. 10303 (acconfig Header): Renamed from acconfig.h. 10304 (20th-century Autoconf 2): Renamed from Autoconf 2.13. 10305 (Writing Testsuites): Renamed from Writing testsuite.at. 10306 (Autom4te Cache): Renamed from autom4te.cache. 10307 10308 * BUGS: Remove mention of VPATH problem, since it's now documented 10309 not to be a bug in the Autoconf build procedure itself, but rather 10310 a problem with the proprietary `make' programs. 10311 10312 * doc/autoconf.texi (Build Directories): Add a cross reference 10313 to VPATH and Make. 10314 10315 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex: 10316 * doc/standards.texi: Sync from gnulib. 10317 10318 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1: 10319 * man/autoscan.1, man/autoupdate.1, man/config.guess.1: 10320 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're 10321 generated automatically. 10322 103232006-12-06 Paul Eggert <eggert@cs.ucla.edu> 10324 10325 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun 10326 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses 10327 the buggy -xc99 option of Forte Developer 7 C on Solaris 9. 10328 103292006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 10330 10331 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the 10332 `CEOF$ac_eof' special marker, the awk script cannot contain a 10333 line matching `^CEOF', so this is not needed any more. 10334 * tests/torture.at (Substitute a newline): Expose the `%!_!# ' 10335 special marker in the test. 10336 103372006-12-06 Stepan Kasal <kasal@ucw.cz> 10338 10339 * tests/tools.at (autom4te preselections): Use `find -newer'; 10340 remove one of the sleeps. 10341 10342 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it 10343 more readable, using ... 10344 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro. 10345 10346 * doc/autoconf.texi (autoheader Invocation): Do not double- 10347 quote the parameter of `AH_BOTTOM' in the example. 10348 103492006-12-05 Stepan Kasal <kasal@ucw.cz> 10350 10351 * doc/autoconf.texi (Configuration Headers): Remove the 10352 example with multiple input files. 10353 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging 10354 multiple input files. 10355 103562006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 10357 10358 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When 10359 creating the awk substitution script, handle one input line at a 10360 time, so that the maximum length of a substituted (multi-line) 10361 value is not limited by the size of the sed pattern space. 10362 The trade-off is a slightly repetitive sed script. 10363 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels 10364 can only have up to 7 characters, due to Solaris 10 /bin/sed. 10365 * tests/torture.at (Substitute a 2000-byte string): Increase the 10366 test with several long lines, they should not be caught by sed 10367 limits any more. 10368 10369 * tests/tools.at (autom4te preselections): New test, to flag 10370 entries missing from autom4te.cfg. 10371 Report by David Byron <dbyron@hheld.com>. 10372 10373 * tests/torture.at (Substitute a 2000-byte string): Actually use 10374 AC_PROG_AWK, so the last change works as intended. 10375 (Substitute and define special characters): Likewise. 10376 (Substitute a newline): Likewise. 10377 10378 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK' 10379 instead of `awk' consistently. 10380 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK. 10381 * tests/torture.at (Torturing config.status): Test both the 10382 result of AC_PROG_AWK and plain awk. 10383 (Substitute a 2000-byte string): Likewise. 10384 (Substitute and define special characters): Likewise. 10385 (Substitute a newline): Likewise. 10386 103872006-12-04 Paul Eggert <eggert@cs.ucla.edu> 10388 10389 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko 10390 can be assigned to a function pointer.

This resurrects the 2000-11-30 patch to 10404 aclang.m4, which was mistakenly removed in the 2001-09-17 patch 10405 to lib/autoconf/c.m4. 10406 104072006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 10408 10409 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test 10410 string for more reliable failure. Wrap the entire test that 10411 causes the broken Solaris printf to dump core, in a subshell, 10412 so the segmentation fault message is reliably suppressed. 10413 Fix shell expansion errors by using /usr/ucb/echo always; 10414 avoid an error on systems without it by another subshell. 10415 Avoid m4 expansion of `$1'. Set the zeroth argument of the 10416 subshell-$as_echo to `as_echo', for better error message. 10417 104182006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 10419 10420 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or 10421 `BASH_SOURCE' contain a newline, set them to empty, as they may 10422 not be unset. 10423 104242006-11-27 Paul Eggert <eggert@cs.ucla.edu> 10425 10426 Turn AC_FUNC_SETVBUF_REVERSED into a noop.

Use "makefile" when talking about makefiles 11753 generally (which might be named "makefile" or "Makefile" or even 11754 "foo.mk"), "Makefile" when talking about a specific makefile 11755 called "Makefile". This unclutters the text from weird quotes 11756 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo} 11757 values" rather than "@var{foo}s" and similar constructs containing 11758 "}s". Use "Make rules" rather than "Makefile rules". Minor 11759 English-language improvements. Change the prefix "sub-" to "sub" 11760 and "re-" to "re". 11761 Put blank lines around examples more consistently. 11762 Avoid "rather" and "very" as intensifiers. 11763 Avoid "will" as an auxiliary. 11764 (Limitations of Make): Split this node into.... 11765 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules): 11766 (Leading _ in Macro Names, Backslash-Newline-Newline): 11767 (Backslash-Newline Comments, Long Lines in Makefiles): 11768 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules): 11769 (obj/ and Make, make -k Status, VPATH and Make): 11770 (VPATH and Double-colon, $< in Explicit Rules): 11771 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic): 11772 (Make Target Lookup, Single Suffix Rules, Timestamps and Make): 11773 New nodes, resulting from splitup of Limitations of Make. 11774 All cross-references changed. Raise the top node from 11775 a section to a chapter, and all subnodes accordingly. 11776 Redo the introductory wording to match the new organization. 11777 (Installation Directory Variables): Use an example that is 11778 closer to what Autoconf actually does. Mention that VPATH's 11779 value should not contain metacharacters or white space. 11780 (Fortran Compiler): Fix a VPATH bug in an example. 11781 (Leading _ in Macro Names): Mention that this problem is no longer 11782 of practical concern. 11783 (VPATH and Make): Reword the advice to make it clearer 11784 that Autoconf and Automake support VPATH in non-GNU make, but 11785 many packages have bugs in this area. 11786 ($< in Explicit Rules): Refer to Build Directories rather 11787 than using a (non-VPATH-safe) example. 11788 (Automatic Rule Rewriting): Mention the sort of disaster that 11789 can ensue with Solaris-style rule rewriting with VPATH. 11790 117912006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 11792 11793 * doc/install.texi (Compilers and Options): Weaken the 11794 suggestion to use GNU make for VPATH builds. 11795 11796 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O, 11797 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM. 11798 11799 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation 11800 in regular expression. 11801 118022006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 11803 11804 * doc/autoconf.texi (Installation Directory Variables): 11805 Drop extra @samp from `@table @samp' item. 11806 (Limitations of Usual Tools): Comment fix. 11807 Do not nest @samp just to point to other table items. 11808 (Writing testsuite.at) <AT_CHECK>: The second argument to 11809 `@dvar' is already @samp'ed. 11810 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise, 11811 do not use @var in the second argument. 11812 118132006-06-07 Paul Eggert <eggert@cs.ucla.edu> 11814 11815 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for 11816 $as_shell.exe too.

Move the definition of ac_files and the 12150 initial `rm' of the candidate files... 12151 (_AC_COMPILER_EXEEXT): ... here and simplify them.

Move comments 12387 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead 12388 of AC_PROG_INSTALL. Output a message saying that we're checking 12389 mkdir -p.

AS_MKDIR_P is now more robust. 12417 * config/install-sh: Don't use 'path' to talk about file names, 12418 as per GNU coding standards. Close a race condition reported by Ralf 12419 Wildenhues and Stepan Kasal. There is still a race condition 12420 on hosts that predate Posix 1003.1-1992, but we can't help this. 12421 Don't mishandle weird characters like space on pre-Posix hosts. 12422 Invoke mkdir at most once per dir arg on pre-Posix hosts. 12423 * doc/autoconf.texi (Programming in M4sh): Cross-reference to 12424 AC_PROG_MKDIR_P from AS_MKDIR_P. 12425 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P 12426 from mkdir.

Be more cautious about the _cv_ variable. 12643 * tests/tools.at (Syntax of the shell scripts): Check the 12644 _cv_ variable once, at first, to avoid an internal autoconf error 12645 when sh -n does not work. 12646 126472006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 12648 12649 * lib/Autom4te/FileUtils.pm: Sync from Automake. 12650 126512006-04-16 Paul Eggert <eggert@cs.ucla.edu> 12652 12653 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't 12654 use ">&-" since we're only 99.999% sure that this is portable, 12655 and since the MinGW bug is fixed in a different way. 12656 * lib/autotest/general.m4 (AT_INIT): Likewise. 12657 126582006-04-16 Stepan Kasal <kasal@ucw.cz> 12659 12660 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck 12661 before opening config.log, to avoid hitting a bug on MinGW. 12662 126632006-04-14 Paul Eggert <eggert@cs.ucla.edu> 12664 12665 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close 12666 AS_MESSAGE_LOG_FD before reopening it onto the log file. 12667 This works around a MinGW bug reported by Eric Paire. 12668 Make sure that all writes to the log file append to it, 12669 rather than possibly losing data. 12670 * lib/autotest/general.m4 (AT_INIT): Likewise. 12671 126722006-04-14 Stepan Kasal <kasal@ucw.cz> 12673 12674 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the 12675 description. 12676 126772006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 12678 12679 * NEWS: Update. 12680 12681 * configure.ac (AC_INIT): Bump to 2.59d. 12682 126832006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 12684 12685 Version 2.59c. 12686 12687 * Makefile.maint (news-date-check): Do not require a leading `*' 12688 before the release date in NEWS. 12689 126902006-04-12 Stepan Kasal <kasal@ucw.cz> 12691 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 12692 12693 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for 12694 the instantiated file do not contain the string 'datarootdir' 12695 but contain @datadir@, @docdir@, @infodir@, @localedir@, or 12696 @mandir@, replace the reference '${datarootdir}' by the value. 12697 * tests/torture.at (datarootdir workaround): New test. 12698 * NEWS: Advertise this temporary fixup. 12699 Based on a patch by Bruno Haible, reported and analyzed by 12700 Paul Eggert and Noah Misch. 12701 127022006-04-12 Eric Blake <ebb9@byu.net> 12703 12704 * tests/autotest.at (Debugging a failed test): Fix comment. 12705 127062006-04-12 Stepan Kasal <kasal@ucw.cz> 12707 12708 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of 12709 all the changes since 2006-04-07. 12710 127112006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 12712 12713 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2' 12714 succeeded, but `ln -s file dir' failed, take care to remove the 12715 leftover target before the next test, to prevent its spurious 12716 failure; also make sure `ln file dir' works before selecting it. 12717 Thanks to Keith Marshall for pointing this out. 12718 * THANKS: Update. 12719 12720 * lib/autotest/general.m4 (AT_INIT): Store quoted variable 12721 assignments in `at_debug_args', so that we put them correctly 12722 in the `run' script. 12723 * tests/autotest.at (Debugging a failed test): Unmark XFAIL. 12724 Reported by Eric Blake. 12725 127262006-04-11 Eric Blake <ebb9@byu.net> 12727 12728 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow 12729 top-level tests after micro-suite has been run.

Proposed by Ralf Wildenhues. 12752 127532006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> 12754 12755 * config/Makefile.am: Add comment to force updated Makefile.in. 12756 12757 * lib/freeze.mk: Fix typo in comment. Unlike the last, white 12758 space only patch to this file, this patch causes the Makefile.in 12759 files that include freeze.mk to be updated, and thus have a 12760 newer time stamp again, which in turn makes a pristine CVS 12761 checkout have correct time stamps. 12762 12763 * Makefile.maint (cvs-sv): New macro, to be used.. 12764 (config.guess-url_prefix, config.sub-url_prefix) 12765 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here; 12766 point to CVS text checkout of Gnulib files. 12767 (copyright-check): Bump current year. 12768 (announcement): Do not hard-wire `./announce-gen'. 12769 (cvs-update): Propagate failures of `cvs' and `move-if-change' 12770 correctly. 12771 * Makefile.cfg (executable-update): Use `chmod a+x' instead of 12772 `chmod +x'. 12773 (wget_files): Update config.guess, config.sub, texinfo.tex by 12774 `wget-update', now that their URLs work again. 12775 127762006-04-10 Paul Eggert <eggert@cs.ucla.edu> 12777 12778 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE. 12779 Problem noted by Paul D.

In general, if it has backslash-newline or the 12805 like, then it doesn't work either to sort or to remove empty 12806 lines. 12807 128082006-04-09 Stepan Kasal <kasal@ucw.cz> 12809 12810 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment. 12811 128122006-04-09 Alexandre Duret-Lutz <adl@gnu.org> 12813 12814 * lib/autom4te.in (Automake-preselections): Preselect 12815 _AM_SUBST_NOTMAKE. 12816 128172006-04-08 Paul Eggert <eggert@cs.ucla.edu> 12818 12819 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an 12820 apostrophe within a single-quoted string, as this is the usual 12821 tradition and is easier to read than '"'"'. Don't rely on the 12822 shell treating "$/" like '$/'. Use a more-consistent indenting 12823 style for the trap. 12824 128252006-04-09 Eric Blake <ebb9@byu.net> 12826 12827 * tests/autotest.at (Backquote command substitution), 12828 (Multiline backquote command substitution): Remove mistaken 12829 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be 12830 applied... 12831 (Parenthetical command substitution, Multiline parenthetical 12832 command substitution): here. 12833 128342006-04-08 Paul Eggert <eggert@cs.ucla.edu> 12835 12836 Import macros from gnulib (often changing their name). 12837 12838 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete. 12839 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE, 12840 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT, 12841 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE, 12842 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T, 12843 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T, 12844 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT, 12845 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, 12846 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, 12847 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS. 12848 The manual mentions Gnulib more prominently. 12849 * doc/autoconf.texi (Gnulib): New node. 12850 (Pointers): Add Gnulib URL. 12851 (Particular Functions): Alphabetize.

Suggested by Paul Pogonyshev. 15768 15769 * config/config.guess, config/config.sub, config/elisp-comp, 15770 config/install-sh, config/mkinstalldirs, config/texinfo.tex, 15771 doc/fdl.texi, doc/standards.texi: Sync with master copy. 15772 15773 * NEWS, TODO, configure.ac, bin/autoscan.in, 15774 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi, 15775 doc/install.texi, lib/Autom4te/Configure_ac.pm, 15776 lib/Autom4te/FileUtils.pm, lib/autoconf/general.m4, 15777 lib/autoconf/programs.m4, lib/autoconf/status.m4, 15778 lib/autotest/general.m4, lib/m4sugar/m4sh.m4, 15779 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at, 15780 tests/tools.at, tests/torture.at: 15781 Use "file name" rather than "filename" or "path", 15782 to be consistent with the terminology of the GNU coding standards. 15783 157842004-08-19 Paul Eggert <eggert@cs.ucla.edu> 15785 15786 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C), 15787 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with 15788 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in 15789 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>. 15790 15791 More fixes to support spaces in the name of the build directory. 15792 This isn't a complete fix but it's an improvement. 15793 15794 * bin/autoconf.as (autom4te_options): New var. 15795 Use it instead of appending to AUTOM4TE, so that we can allow 15796 spaces in the build directory's absolute name. 15797 * bin/autoheader.in ($autoconf): Allow spaces in file names. 15798 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK, 15799 AT_CHECK_NOESCAPE): Likewise. 15800 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir, 15801 main program): Likewise. 15802 158032004-08-18 Paul Eggert <eggert@cs.ucla.edu> 15804 15805 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses. 15806 From Ralf Corsepius in: 15807 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html 15808 158092004-08-12 Paul Eggert <eggert@cs.ucla.edu> 15810 15811 * doc/autoconf.texi (Function Portability): Document isinf and 15812 and isnan.

Reported by J C Fitzgerald in 15821 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>. 15822 158232004-08-04 Alexandre Duret-Lutz <adl@gnu.org> 15824 15825 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro. 15826 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess. 15827 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh. 15828 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE. 15829 * lib/autom4te.in (Automake-preselections): Preselect 15830 AC_REQUIRE_AUX_FILE.

Problem reported by Patrick Welche via 15849 Gary V. Vaughan. 15850 * doc/autoconf.texi (Shellology): Note that set -o posix is 15851 useful for pkdsh, too. 15852 158532004-06-24 Paul Eggert <eggert@cs.ucla.edu> 15854 15855 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require 15856 _AS_UNSET_PREPARE, so that we can use $as_unset directly. 15857 Don't fail if ENV or BASH_ENV is readonly. 15858 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL, 15859 etc. are read only. Problem reported by Ludovic Courtes. 15860 158612004-06-23 Noah Misch <noah@cs.caltech.edu> 15862 15863 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is 15864 zsh, disable GLOB_SUBST to avoid backslash handling problems. 15865 (trivial change) 15866 158672004-06-04 Paul Eggert <eggert@cs.ucla.edu> 15868 15869 * doc/autoconf.texi (File System Conventions): Warn about 15870 names like "aux". Problem reported by Eric Blake. 15871 15872 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division 15873 by zero instead of array size, so that we can use any arithmetic 15874 constant expression (instead of requiring an integer constant 15875 expression). This allows us to test expressions like DBL_MAX < 15876 LDBL_MAX, which didn't conform to the C standard using the old 15877 method. 15878 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON, 15879 now that we can do floating-point tests at compile time. 15880 158812004-06-02 Paul Eggert <eggert@cs.ucla.edu> 15882 15883 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX 15884 and LDBL_EPSILON, as the resulting expression isn't an 15885 integer constant expression and violates the C standard. 15886 Problem reported by Nelson H. F. Beebe. Also, check 15887 for "L" suffix, and check that long double doesn't have 15888 worse range or precision than double, that mixed-mode 15889 arithmetic doesn't generate a diagnostic, that double 15890 constants fit in long double. 15891 158922004-06-03 Kevin Ryde <user42@zip.com.au> 15893 15894 * doc/autoconf.texi (Function Portability): Add notes on free(NULL), 15895 malloc(0) and realloc(NULL,size). 15896 15897 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by 15898 Bob Proulx. 15899 159002004-05-31 Paul Eggert <eggert@cs.ucla.edu> 15901 15902 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug 15903 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003].

Patch reported by Ralf Wildenhues in 15920 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>. 15921 15922 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a 15923 function F exists if the compiler and linker let you compile an 15924 expression like (F != 0). Recent versions of GCC optimize away 15925 the reference to F in that case, since every function address must 15926 be nonzero, so the link succeeds even if F does not exist. 15927 Problem reported by Manu in 15928 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>. 15929 15930 * doc/autoconf.texi (Systemology): Standardize on the spelling of 15931 "Unix". Many uses changed. 15932 (Limitations of Builtins): Explain better why the ! command isn't 15933 portable. 15934 159352004-05-22 Alexandre Duret-Lutz <adl@gnu.org> 15936 15937 * lib/autom4te.in (Automake-preselections): Preselect 15938 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS. 15939 159402004-05-19 Kevin Ryde <user42@zip.com.au> 15941 15942 * doc/autoconf.texi (Function Portability): Add strerror_r, cross 15943 referencing AC_FUNC_STRERROR_R. 15944 15945 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID, 15946 note pessimistic assumption when cross compiling. 15947 159482004-05-16 Paul Eggert <eggert@cs.ucla.edu> 15949 15950 * doc/autoconf.texi (Limitations of Make): Note that BSD make 15951 (until 2004) invoked subcommands with sh -e, contra POSIX. 15952 Reported by Kevin Ryde. 15953 159542004-05-10 Eric Sunshine <sunshine@sunshineco.com> 15955 15956 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to 15957 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e. 15958 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as 15959 `test -f " /usr/bin/grep"', which _always_ failed. 15960 (AC_PROG_SED): Ditto bogus PATH fix. 15961 * autoconf.texi (AC_PROG_GREP): Properly document that this macro 15962 requires that grep correctly supports _multiple_ `-e' options, rather 15963 than stating only that grep should accept `-e'. 15964 159652004-05-03 Paul Eggert <eggert@cs.ucla.edu> 15966 15967 Port to C99, which requires that 'exit' be declared. 15968 15969 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT 15970 to ensure that stdlib.h is included. 15971 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP, 15972 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK, 15973 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise. 15974 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise. 15975 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise. 15976 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h> 15977 when using 'exit' in a test; C99 requires that 'exit' be declared. 15978 159792004-05-02 Paul Eggert <eggert@cs.ucla.edu> 15980 15981 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP 15982 now prefers 'grep' implementations that accept -e. 15983 (Limitations of Usual Tools): Describe problems of traditional 15984 egrep and fgrep with long input lines, and of traditional grep 15985 with -e. 15986 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too. 15987 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell. 15988 All callers changed. Append /usr/xpg4/bin to the PATH, for 15989 Solaris. 15990 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother 15991 the user with complaints about multiple -e options. 15992 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep. 15993 Define it with AC_PROG_GREP. 15994 * configure.ac (AC_PROG_GREP): Add. 15995 * lib/freeze.mk (GREP): New macro. 15996 159972004-05-02 Eric Sunshine <sunshine@sunshineco.com> 15998 15999 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as 16000 a possible candidate only after all others fail, rather than 16001 consulting it first. This improves backward compatibility by 16002 better reflecting the way shell selection occurred in previous 16003 versions of Autoconf, and should help to avoid triggering latent 16004 problems in other packages, such as the one in Automake where zsh 16005 is not handled robustly: 16006 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html 16007 Although it is not Autoconf's responsibility to work around 16008 problems in Automake, it nevertheless makes sense to avoid 16009 introducing unnecessary incompatibilites. 16010 160112004-04-22 Albert Chin-A-Young <china@thewrittenword.com>, 16012 Gary V.

still several issues: (i) there are too many runs of m4 17167 (one for include, one for warnings, and some more), (ii) warnings 17168 spreading on several lines are not handled gracefully, (iii) the 17169 code meant to have the call stack display for errors does not work 17170 (its handling should move from m4 to autom4te). 17171 17172 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs): 17173 Use them. 17174 (@preselect): Add m4_warn. 17175 ($exit_status): Remove, use $exit_code. 17176 ($help): Use Autom4te::ChannelDefs::usage. 17177 (&handle_m4): No longer define the m4_warnings. 17178 At each run, extract and report the warnings. 17179 Always cache the result, including if the exit status is on 17180 failure, since if nothing changes, we should result in the same 17181 failure, hence we can use the cache. 17182 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse) 17183 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn): 17184 Remove. 17185 (m4_warn): Redefine as a do-nothing: it is its invocation that 17186 matters, as warnings are now reported via traces. 17187 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of 17188 the contents of m4_warn: make it _call_ m4_warn, so that tracing 17189 the latter reveals calls to the former. 17190 17191 Adjust the tests. 17192 17193 * tests/m4sugar.at (m4@&t@_warn): Use existing

See: 17334 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html 17335 (This really should be 'intptr_t', not 'long', but that would 17336 take more work.) 17337 173382003-06-25 Akim Demaille <akim@epita.fr> 17339 17340 * lib/Makefile.am (autom4te.cfg): Make it read only. 17341 Depend on Makefile since it contains substitutions. 17342 From Paolo Bonzini. 17343 * lib/autom4te.in (args): Add local.at? for Autotest args. 17344 This change was made on autom4te.cfg which is generated. 17345 Reported by Raja R.

This fixes 1. the fact that when testing 17356 Autoconf there are many many config.log, 2. the incorrect use of 17357 top_srcdir to find config.log. 17358 Don't mix the detailed output of failed test with the summary of 17359 failures. Rather, append detailed log afterwards. 17360 173612003-06-23 Akim Demaille <akim@epita.fr> 17362 17363 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being 17364 always run: output config.log on $at_group_log. 17365 173662003-06-23 Akim Demaille <akim@epita.fr> 17367 17368 * tests/torture.at (#define header templates): Don't use quotes in 17369 C++ comments as it puzzles Emacs' sh font-lock-mode. 17370 173712003-06-23 Akim Demaille <akim@epita.fr> 17372 17373 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice. 17374 * lib/autom4te.cfg (args): Add local.at? for Autotest args. 17375 * tests/atspecific.m4: Rename as... 17376 * tests/local.at: This. 17377 * tests/suite.at: Move the globals into... 17378 * tests/local.at: here. 17379 * tests/Makefile.am: Adjust. 17380 * doc/autoconf.texi (testsuite Scripts): Adjust. 17381 173822003-06-21 Kevin Ryde <user42@zip.com.au> 17383 17384 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an 17385 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby 17386 ensuring we add -std1 for full-ANSI. 17387 17388 * doc/autoconf.texi (hdrindex): New macro. 17389 Add index entries for portability of various standard header files. 17390 173912003-06-20 Akim Demaille <akim@epita.fr> 17392 17393 * configure.ac: Bump to 2.57b. 17394 173952003-06-20 Akim Demaille <akim@epita.fr> 17396 17397 Version 2.57a. 17398 173992003-06-20 Akim Demaille <akim@epita.fr> 17400 17401 * bin/autom4te.in: Don't rely on $HOME being defined. 17402 Reported by Marc Espie as PR/233. 17403 174042003-06-20 Akim Demaille <akim@epita.fr> 17405 17406 * lib/autotest/general.m4: Use at_times_file only if used. 17407 From Nicolas Joly. 17408 174092003-06-20 Akim Demaille <akim@epita.fr> 17410 17411 * config/config.guess, config/config.sub, config/elisp-comp, 17412 * config/install-sh, config/mkinstalldirs, doc/standards.texi: 17413 Update from masters. 17414 174152003-06-11 Paolo Bonzini <bonzini@gnu.org> 17416 17417 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF 17418 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro. 17419 (TEST_SCRIPT): New diversion. 17420 (AT_SETUP): Divert output to TEST_SCRIPT and move some code... 17421 (AT_CLEANUP): ...to here.

Problems reported by 17484 Matthew Mueller in <http://bugs.debian.org/120704> and by 17485 Keith Bostic in 17486 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>. 17487 In the test, use the test declaration before including <stdlib.h>, 17488 as that's closer to how it'll be used. 17489 174902003-05-23 Akim Demaille <akim@epita.fr> 17491 17492 * doc/autoconf.texi (Header Portability): ucred.h. 17493 From Ian Redfern. 17494 174952003-05-22 Paolo Bonzini <bonzini@gnu.org> 17496 17497 Overhaul Autotest's logging: generate separate log files 17498 in testsuite.dir/NNN/testsuite.log, and append them to 17499 testsuite.log instead of re-running the test verbosely. 17500 17501 * lib/autotest/general.m4 (AT_INIT): Use a single redirected 17502 file descriptor, write 0 to at_status_file instead of setting 17503 at_status=0, initialize some new variables (at_status_file, 17504 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft 17505 to rerun the tests, instead append the at_group_log to the 17506 at_suite_log when a test fails. 17507 (AT_SETUP): pipe the test case's output into at_tee_pipe, 17508 with the AS_MESSAGE_LOG_FD redirected to stdout. 17509 (AT_CLEANUP): save the output status in $at_status_file 17510 and restore it, redirect the AS_MESSAGE_LOG_FD back to 17511 its original place. 17512 (AT_CHECK): since tests are run with a redirected stdout, 17513 and used to be re-run in verbose mode, turn some $at_verbose 17514 into echo, and don't redirect the output of testing stdout 17515 and stderr. 17516 17517 * lib/autotest/autoconf.texi (testsuite Scripts): Update 17518 the name of the debugging directory and information about 17519 its contents. 17520 175212003-05-22 Paolo Bonzini

This patch was 18838 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D.

Use a shell for-loop for this rather than an m4 loop, 18852 to shorten the output script. 18853 188542002-08-30 Paul Eggert <eggert@twinsun.com> 18855 18856 * doc/autoconf.texi (Special Shell Variables): Mention POSIX 18857 1003.1-2001's requirements for CDPATH. Give a simpler workaround 18858 for the CDPATH problem. Document PWD. 18859 (Limitations of Builtins): Document the problem that "cd $foo" and 18860 "ls $foo" may refer to different directories in shells conforming 18861 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset" 18862 example, since the old example is now out of date. 18863 18864 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd 18865 FOO" and "ls FOO" talk about different directories; this catches 18866 problems when POSIX 1003.1-2001 "cd" fails due to symlink 18867 spaghetti. 18868 18869 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead 18870 of rolling our own unset. 18871 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since 18872 in practice we needn't worry about CDPATH if unset doesn't work. 18873 18874 * Makefile.in, aclocal.m4, bin/Makefile.in, 18875 config/Makefile.in, doc/Makefile.in, lib/Makefile.in, 18876 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in, 18877 lib/autoscan/Makefile.in, lib/autotest/Makefile.in, 18878 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in, 18879 tests/Makefile.in: Regenerate with Automake 1.6.3. 18880 18881 * config/config.guess, config/config.sub, config/mkinstalldirs: 18882 Update. 18883 18884 * configure: Regenerate with self. 18885 188862002-08-30 Kevin Ryde <user42@zip.com.au> 18887 18888 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc" 18889 default output. 18890 188912002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE> 18892 18893 * bin/autom4te.in (Request::load): Correctly test for "do" read 18894 failure. 18895 188962002-08-29 Akim Demaille <akim@epita.fr> 18897 18898 * lib/Autom4te/General.pm (&xqx): New. 18899 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by 18900 hand, which is not portable. 18901 (&error): New. 18902 * bin/autom4te.in: Use them. 18903 Use &error instead of die. 18904 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies): 18905 Adjust. 18906 189072002-08-17 Paul Eggert <eggert@twinsun.com> 18908 18909 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the 18910 default list of compilers to try, since it was long ago superseded 18911 by the ksh fc builtin. Suggested by Steven G. Johnson. 18912 189132002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr> 18914 18915 * doc/autoconf.texi (Invoking autom4te): End the option table, 18916 fixing a bug introduced by the previous patch. 18917 (Limitations of Make): Add a 'target lookup' subentry in the 18918 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'. 18919 189202002-07-29 Mark D.

The old ones were 21056 one line out... 21057 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as 21058 the documentation claims it should (and how it behaved in 2.13). 21059 210602001-09-18 Akim Demaille <akim@epita.fr> 21061 21062 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in 21063 the AC_CONFIG_COMMANDS invocation. 21064 This also solves the name clash problems. 21065 Don't set the package's ID. 21066 * lib/m4sugar/Makefile.am (version.m4): Revamp. 21067 No longer to be shipped. 21068 (version.in): Remove. 21069 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4, 21070 * lib/autoconf/status.m4: Adjust. 21071 Use `m4_PACKAGE_STRING'. 21072 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now 21073 the only optional argument is the name of the test suite. 21074 Expect `package.m4' to define the package signature. 21075 * lib/autom4te.in (Autotest): Add `package.m4?'. 21076 * tests/Makefile.am (package.m4): New. 21077 * tests/suite.at: ifnames is a victim. 21078 210792001-09-18 Akim Demaille <akim@epita.fr> 21080 21081 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL, 21082 AC_LIBSOURCE, AC_CONFIG_FILES. 21083 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested 21084 program version string doesn't match the package's. 21085 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space 21086 after `(cached)'. 21087 210882001-09-17 Paul Eggert <eggert@twinsun.com> 21089 21090 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)): 21091 Allow expression to return any value that can fit into unsigned long 21092 (not int, as before). Check for output errors. 21093 210942001-09-17 Bruno Haible <haible@ilog.fr> 21095 21096 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)): 21097 Always include <stdio.h> and <stdlib.h>. Evaluate 21098 the expression in an extra function before these includes. Call 21099 fprintf "%d" only after ensuring the argument is of type 'int'. 21100 Reported by Wayne Chapeskie <waynec@spinnaker.com>. 21101 211022001-09-17 Paul Eggert <eggert@twinsun.com> 21103 21104 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4 21105 or CFLAGS=-O5. In that case, the linker has a relaxed view of 21106 fatal errors, and AC_CHECK_LIB causes it to include libraries even 21107 when they don't exist. 21108 21109 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS, 21110 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't 21111 need it. 21112 21113 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty 21114 version with the version used by fileutils 4.1, except use 21115 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if 21116 we don't need it. 21117 21118 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior. 21119 211202001-09-13 Akim Demaille <akim@epita.fr> 21121 21122 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line 21123 _first_. 21124 Reported by Gerrit P. Haase. 21125 211262001-09-13 Akim Demaille <akim@epita.fr> 21127 21128 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that 21129 m4_defn'ing is valid. 21130 211312001-09-13 Akim Demaille

consistency. 21150 Set at_victims. 21151 (AT_VICTIMS): Similar to AT_KEYWORDS. 21152 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape. 21153 211542001-09-13 Akim Demaille <akim@epita.fr> 21155 21156 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs. 21157 211582001-09-13 Akim Demaille <akim@epita.fr> 21159 21160 * lib/autotest/general.m4 (AT_INIT): Create and remove 21161 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple 21162 test suites can cohabit. 21163 211642001-09-13 Akim Demaille <akim@epita.fr> 21165 21166 * tests/mktests.sh: Don't output banners for empty test files. 21167 211682001-09-13 Akim Demaille <akim@epita.fr> 21169 21170 Test suites can be run independently of configure. 21171 21172 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New. 21173 *

everywhere as, 21252 in addition, it introduces useless differences in logs. 21253 (AT_INIT): Let atconfig and atlocal be both optional. 21254 Adjust PATH computation. 21255 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH. 21256 212572001-09-07 Akim Demaille <akim@epita.fr> 21258 21259 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon 21260 m4sugar/version.m4. 21261

`dnl.at', for if even 21275 the maintainer is dumb enough to do that... 21276 21277 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your 21278 excellence in M4 quotation: consider `__file__' is active. 21279 21280 And BTW, when invoking m4, pass the --include in the right order: 21281 the wrong one. 21282 21283 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to 21284 4m. 21285 212862001-09-05 Akim Demaille <akim@epita.fr> 21287 21288 * lib/Autom4te/XFile.pm: New lib file. 21289 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in, 21290 * bin/autoheader.in:

<akim@epita.fr> 21298 21299 * lib/Autom4te/General.pm (&getopt): Work around the `-' Getopt bug. 21300 * bin/autoheader.in, bin/autoupdate.in (&parse_args): Adjust. 21301 21302 * bin/autoscan.in: Use `getopt' and `find_files' etc. 21303 Add -I, --include support. 21304 * doc/autoconf.texi (autoscan Invocation): Adjust. 21305 213062001-09-05 Akim Demaille <akim@epita.fr> 21307 21308 CVS GNU M4 doesn't like `undefine(undefined)'. 21309 21310 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros): 21311 New, extracted from main. 21312 Use IO::File wherever possible. 21313 (input.m4): Be constant, use -I instead of hard coding $tmp. 21314 Therefore be a quoted heredoc. 21315 Don't invoke `_au_disable', since ac was not loaded, but just 21316 `unm4.m4'. 21317 213182001-08-31 Akim Demaille <akim@epita.fr> 21319 21320 Version 2.52d. 21321 213222001-08-31 Akim Demaille <akim@epita.fr> 21323 21324 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the 21325 previous patch. 21326 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'. 21327 213282001-08-31 Akim Demaille <akim@epita.fr> 21329 21330 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has 21331 serious problems handling heredocs in heredocs. 21332 Reported by Nicolas Joly. 21333 213342001-08-31 Akim Demaille <akim@epita.fr> 21335 21336 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros. 21337 (Making testsuite Scripts): Update. 21338 213392001-08-31 Akim Demaille <akim@epita.fr> 21340 21341 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg. 21342 213432001-08-31 Akim Demaille <akim@epita.fr> 21344 21345 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'. 21346 (testsuite Scripts): There is no such thing as `atconfig.in'. 21347 And actually one diagram is missing: test suite runtime. 21348 213492001-08-31 Akim Demaille <akim@epita.fr> 21350 21351 * lib/Autom4te/General.pm (&find_file): Browse the includes in the 21352 inverse order. 21353 213542001-08-31 Akim Demaille <akim@epita.fr> 21355 21356 * bin/autoupdate.in (@include): `installcheck' revealed the path 21357 to m4sugar was lacking! 21358 213592001-08-31 Akim Demaille <akim@epita.fr> 21360 21361 * man/Makefile.am (.x.1): We really have to pass 21362 autom4te_perllibdir. 21363 213642001-08-31 Akim Demaille <akim@epita.fr> 21365 21366 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to 21367 debug scripts, in particular passing explicitly listed tests to 21368 run is stupid. 21369 213702001-08-31 Akim Demaille <akim@epita.fr> 21371 21372 * bin/autom4te.in (&parse_args): Strip `.' from `@include'. 21373 * bin/autoupdate.in: Use --include, -I, and --force, -f, too. 21374 Use directly autom4te, not autoconf. 21375 * tests/autoupdate: $top_srcdir/lib is needed too for melt files. 21376 213772001-08-31 Akim Demaille <akim@epita.fr> 21378 21379 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol. 21380 * bin/autoheader.in (%symbol): Strip arguments of macros. 21381 213822001-08-31 Akim Demaille <akim@epita.fr> 21383 21384 * doc/autoconf.texi: Catch up -I, --include changes. 21385 213862001-08-31 Akim Demaille <akim@epita.fr> 21387 21388 * bin/autom4te.in (&parse_args): Die on unknown languages. 21389 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no 21390 need for autoconf. 21391 Promote --include over --macrodir and other obsolete options. 21392 213932001-08-31 Akim Demaille <akim@epita.fr> 21394 21395 * lib/Autom4te/General.pm ($version, $help, &getopt): New. 21396 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them. 21397 * bin/autom4te.in ($autoconf): Pass --force. 21398 `print $out' doesn't print `$_' but `$out'. 21399 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir. 21400 (autoheader): Pass --force since the test suite goes too fast for 21401 the time stamps. 21402 Adjust to the new autoheader messages. 21403 214042001-08-31 Akim Demaille <akim@epita.fr> 21405 21406 * bin/autoheader.in: Handle the acconfig.h etc. junk files. 21407 Check the completeness of the #template. 21408 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/. 21409 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER 21410 invocation. 21411 214122001-08-31 Akim Demaille <akim@epita.fr> 21413 21414 * lib/Autom4te/General.pm (&find_file, &update_file): New. 21415 * bin/autoupdate.in, bin/autoheader.in: Adjust. 21416 Drop AC_MACRODIR dead for real. 21417 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says 21418 `autoheader: `config.hin' is created'. 21419 * tests/tools.at (Syntax of the Perl scripts): Check autoheader. 21420 214212001-08-31 Akim Demaille <akim@epita.fr> 21422 21423 * bin/autoheader.in: Rewrite in Perl. 21424 * tests/autoheader: Adjust. 21425 214262001-08-31 Akim Demaille <akim@epita.fr> 21427 21428 * bin/autoconf.in (--include, -I): New option. 21429 Map --localdir, --autoconf-dir onto it. 21430 Forward autom4te's options instead of interpreting them. 21431 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir): 21432 There is no such envvar since the inception of autom4te.cfg. 21433 * bin/autom4te.in (&parse_args): Uniquify `@include'. 21434 * bin/autoupdate.in: Adjust, and perform more control. 21435 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust. 21436 * tests/autoconf: Dittowise. 21437 214382001-08-31 Akim Demaille <akim@epita.fr> 21439 21440 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'. 21441 * bin/autom4te.in (&find_file): Support `FILE?' standing for 21442 optionally `FILE'. 21443 Use -e, not -f, since /dev/null for instance is OK. 21444 (&parse_args): Adjust. 21445 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'. 21446 214472001-08-31 Akim Demaille <akim@epita.fr> 21448 21449 * configure.ac: Also find tested executables in bin. 21450 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in, 21451 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the 21452 installed peer executables, only PATH is allowed to resolve it. 21453 Pass `autoconf_dir' via options, not via invisible envvars. 21454 * lib/Autom4te/General.pm (&find_peer): Remove. 21455 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives 21456 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.

<duret_g@epita.fr> 22032 22033 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE, 22034 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN. 22035 * doc/autoconf.texi (C Compiler Characteristics): Update

from an object file when cross-compiling. 22042 Based on code by Guido Draheim <Guido.Draheim@gmx.de>. 22043 220442001-08-10 Akim Demaille <akim@epita.fr> 22045 22046 * bin/autom4te.in (&handle_output): Don't use `grep' with side 22047 effects. 22048 Suggested by Russ Allbery. 22049 220502001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de> 22051 22052 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the 22053 current $prefix to the sub-configures. 22054 220552001-08-09 Tim Van Holder <tim.van.holder@pandora.be> 22056 22057 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable 22058 extension (needed on BeOS). Reported by Guido van Rossum. 22059 220602001-08-09 Akim Demaille <akim@epita.fr> 22061 22062 * bin/autom4te.in ($icache): Load it only if older than autom4te. 22063 220642001-08-07 Akim Demaille <akim@epita.fr> 22065 22066 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be 22067 removed. 22068 (at-setup-line): Huh? Be a variable `at_setup_line', not a file. 22069 No need to remove the files before and after the each test, before 22070 each test and at the end of the suite is enough. 22071 Display only the children `times', not the shell's. 22072 If the test failed or was skipped, at-times is not available. 22073 220742001-08-07 Akim Demaille <akim@epita.fr> 22075 22076 Always produce testsuite.log, including when there are no 22077 failures. This helps getting information on skipped tests, and 22078 duration of the tests. Err, implement the latter btw. 22079 22080 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log. 22081 Dump information on the first run of each test. 22082 (AT_CLEANUP): Create `at-times' containing the duration of the 22083 test group. 22084 220852001-08-07 Akim Demaille <akim@epita.fr> 22086 22087 The use of `dumpstat' revealed that `len' was used although it 22088 should not. m4_text_wrap was using it, but in the Autoconf world 22089 where it is legal. Hence (i) test M4sh in its own world, not 22090 Autoconf's, and (ii), ahem, fix the bug :) 22091 22092 * lib/autotest/general.m4: Be sure the set good quotes, as tracing 22093 does not like `' instead of []. 22094 (AT_INIT): Forbid `^_?AT_'. 22095 And don't output such tokens. 22096 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g', 22097 `script.as', and `autom4te.cache'. 22098 Remove `empty' and `macro' which are no longer used. 22099 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New. 22100 * tests/m4sugar.at: Use it. 22101 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'. 22102 221032001-08-07 Akim Demaille <akim@epita.fr> 22104 22105 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option. 22106 221072001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr> 22108 22109 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution. 22110 221112001-08-04 Akim Demaille <akim@epita.fr> 22112 22113 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE) 22114 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not 22115 AC_TRY_LINK. 22116 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise. 22117 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS) 22118 (AC_F77_MAIN): Likewise. 22119 221202001-08-04 Akim Demaille <akim@epita.fr> 22121 22122 Don't rely on M4sugar outputting the patterns in files, since we 22123 might process the output _without_ running m4, hence without these 22124 files. 22125 22126 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'. 22127 * bin/autom4te.in (@Request::includes): Remove, unused. 22128 (@Request::source): Rename as... 22129 (@Request::input): this. 22130 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'. 22131 (&handle_output): Fetch the patterns from the traces. 22132 `$forbidden' and `$allowed' are constant: use m//o. 22133 (&handle_m4): M4sugar no longer wants `m4_tmpdir'. 22134 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only. 22135 221362001-08-04 Akim Demaille <akim@epita.fr> 22137 22138 `autoconf && autoheader' is sped up. Now, speed up `autoheader && 22139 autoconf', i.e., in addition to caching traces, cache the output. 22140 22141 * bin/autom4te.in (Request::cache): Rename as... 22142 (Request::id): this. 22143 ($cache, $icache, $tcache, $ocache): New. 22144 (&handle_m4): Save M4 output in the cache instead of $tmp. 22145 (&handle_output): Adjust. 22146 (&up_to_date_p): Check that the output cache is up to date too. 22147 (top level): Run `&handle_m4' iff force or the cache is invalid. 22148 Run `&handle_output' if the output cache is more recent. 22149 221502001-08-04 Akim Demaille <akim@epita.fr> 22151 22152 * bin/autom4te.in ($force): New. 22153 (&parse_args, &print_usage): -f, --force is a new option. 22154 (&handle_output): CPP directives might have spaces after `#'. 22155 (&parse_args): The first file only can be frozen. 22156 221572001-08-04 Akim Demaille <akim@epita.fr> 22158 22159 Don't let autom4te compute the `include' traces several times: 22160 first check that the trace cache file is up to date, and then 22161 compare its timestamp with that of the output. 22162 22163 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize 22164 the preamble. Don't require 5.005 as Autom4te::General does it, 22165 and better yet (use `use', not `require'!). 22166 * lib/Autom4te/Struct.pm: Rename the last occurrences of 22167 Class::Struct as Autom4te::Struct. 22168 * lib/Autom4te/General.pm (File::stat): Use it. 22169 (&mtime): New, export it. 22170 * bin/autom4te.in: Use it. 22171 Declare `$req' is invalid if it is outdated. 22172 Don't declare it valid before saving it if something went wrong. 22173 221742001-08-04 Akim Demaille <akim@epita.fr> 22175 22176 Autom4te shall not encode Autoconf data, and preselecting traces 22177 must be proposed to the users. 22178 22179 * bin/autom4te.in (@required_trace): Remove. 22180 (@preselect): New. 22181 (&parse_args, &print_usage): -p, --preselect is a new option. 22182 (&up_to_date_p): Adjust. 22183 * bin/autoconf.in: Preselect some Autoconf macros. 22184 221852001-08-04 Akim Demaille <akim@epita.fr> 22186 22187 * tests/tools.at (autoconf --trace: user macros): Check traces on 22188
