section, Eved off from `Preset Output Variables', i.e., was a
small part of it, grew independent, and is its equal (at least).
(Coding Style): `$#' padding.
* Makefile.am (editsh, editpl): Do what the doc says you do: use
@datadir\@ instead of @''datadir''@.
way of accessing Fortran name-mangling information other than
through CPP, and without having to know the different possible
name-mangling schemes.
* autoconf.texi: Documented AC_F77_FUNC
`size_t' which are often used too.
Fix a bug which prevents recognition of `bool' and `char'.
(_AC_CHECK_TYPE_MAYBE_TYPE_P): New macro.
(AC_CHECK_TYPE): Use it.
_AC_F77_NAME_MANGLING.
(_AC_F77_NAME_MANGLING): Use independent checks for the
name mangling of symbols with and without underscores.
Use algorithm with for loops instead of recursive macro calls.
(AC_F77_WRAPPERS): Adapt to changes in _AC_F77_NAME_MANGLING.
* doc/autoconf.texi (Fortran 77 Compiler Characteristics):
Remove documentation of AC_F77_NAME_MANGLING.
Remove documentation of f77_case and f77_underscore.
Replace AC_F77_FUNC_WRAPPER with AC_F77_WRAPPERS.
Macros): Don't give boring internal details.
(Language Choice): Typo.
(Limitations of Builtins): Some about `!', `set', `$@'.
(Coding Style): Some about $[@] quotation.
Some about cross-compilation.
In fact, rename this option as -A, --autoconf-dir.
* autoconf.sh: Complain when -m, --macrodir is used.
Accept -A, --autoconf-dir.
Use $autoconf_dir instead of $AC_MACRODIR.
Adjust --help.
* autoheader.sh: Likewise.
* autoscan.sh: Likewise.
* autoupdate.sh: Likewise.
Use $optarg.
* autoreconf.sh: Likewise.
* doc/autoconf.texi: Adjust.
* tests: Adjust the test suite.
behavior of AC_CONFIG_HEADERS and AC_CONFIG_FILES with respect to
absolute and relative filenames, and stdin/stdout.
(config.status invocation): Likewise.
* autoreconf.sh (update.sh): Use `ls -1dt' instead of `-lt'.
Use test instead of sed.
<automake>: If automake is used, always run it: it has its own
mechanism not to update if unneeded.
In fact, honor the most recent specification in the concatenation
of `syntax',$WARNINGS,<options> in that order.
Implement support for `none' and `noCATEGORY' so that the options
may override the previous choices.
Suggested by Didier Verna.
* acgeneral.m4 (_AC_WARNING_IFELSE): New macro.
(AC_WARNING_IFELSE): Use this macro to implement the new specs.
(AC_WARNING): The empty category must not be used, default to
`syntax'.
* doc/autoconf.texi (autoconf Invocation, Reporting Messages): Adjust.
* autoconf.sh: Adjust.
Use `optarg' to fetch the arguments of options.
Fix a bug in the handling of `--trace='.
* acgeneral.m4 (AC_CACHE_VAL): Typo: the macro was complaining iff
it shouldn't have.
* doc/autoconf.texi: Free Franc,ois Pinard from iftex and ifinfo,
use @,c.
Don't use `@code{m4}' when you mean M4, just as you shall not say
`@code{cc}' when you refer to the C language.
* acgeneral.m4 (build_alias): Set to host_alias if --build is not
given but --host is, and enable cross-compile auto-detection. If
both are, and are different, enable cross compilation.
(AC_CANONICAL_HOST): Adjust help message.
(cross_compiling): Enclose in quotes when testing.
* aclang.m4 (_AC_LANG_COMPILER_WORKS): If cross_compiling is
maybe, set it to yes or no depending on the result of the
execution test.
* doc/autoconf.texi: Document the change.
* doc/install.texi: Likewise.
$AUTOMAKE and $ACLOCAL.
Pass --verbose to the tools.
Avoid using plenty of variables, just append to existing
variables.
* doc/autoconf.texi: List options in the order --help, --version,
--verbose, --debug, and then specific options.
(Specifying Names): When describing the system triplets, use the
same names as the shell variables.
(System Type Variables): Delete, merge its content into...
(Canonicalizing): here.
Clarify the difference between the `foo_target' and `foo'
variables.
AC_CONFIG_COMMANDS, AC_CONFIG_FILES): Use a shell variable instead
of an m4 variable to store what must be done, so that sh
conditionals are honored.
(_AC_OUTPUT_LINKS, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_COMMANDS, _AC_OUTPUT_FILES): Adjust.
* tests/semantics.m4: Test the four AC_CONFIG sisters.
* doc/autoconf.texi (Configuration Actions): Promote the use of
literals, show it works properly with sh conditionals.
* acgeneral.m4 (AC_OUTPUT_MAKE_DEFS) <confdef2opt.sed>: Reset the
t flag between each cycle.
* doc/autoconf.texi (Limitations of Usual Tools): Some about the t
flag in sed.
* acgeneral.m4 (_AC_COMPUTE_INT_COMPILE): Do not put two shell
variable assignments in one shell command.
* doc/autoconf.texi (Shell Substitutions): Document.
