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.
when detecting the verbose flag than when scanning for linker
options, and as a result the former test failed (under AIX/xlf).
* aclang.m4 (_AC_PROG_F77_V_OUTPUT): New macro to get the
output of linking an F77 program with a given verbose flag,
and preprocess it as required to scan for linker flags.
(_AC_PROG_F77_V): Use the above macro here...
(AC_F77_LIBRARY_LDFLAGS): ...and here, enforcing consistency.
behavior of AC_CONFIG_HEADERS and AC_CONFIG_FILES with respect to
absolute and relative filenames, and stdin/stdout.
(config.status invocation): Likewise.
* autoheader.sh: Be more verbose, and always report your name in
verbose messages.
* autoconf.sh: Likewise.
* autoreconf.sh: Likewise.
(update.sh): Redirect ls's stderr to /dev/null.
leads to unnecessary warnings if both C and Fortran are checked.
(AC_PROG_F77_C_O): AC_REQUIRE AC_PROG_F77 instead of pretend you
need to be AC_BEFORE it.
causes the compiler to output verbose linking information.
(AC_F77_LIBRARY_LDFLAGS): Use _AC_PROG_F77_V instead of
simply "-v"
(AC_F77_LIBRARY_LDFLAGS): New algorithm to parse flags, uses
set/shift shell commands.
(AC_F77_LIBRARY_LDFLAGS): Set FLIBS at end, after determining
ac_cv_flibs.
* 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.
* acgeneral.m4 (AC_SHELL_DIRNAME): When using m4 the argument
is named `$1' not `$dir'.
When using m4 you ought to quote properly.
When using m4, you should check that there are not too many shell
quotes (inside the macro itself, and where it is called).
When you do this, Autoconf, hm, works better.
* acgeneral.m4 (_AC_INIT_HELP): Direct reader to descriptions
of useful variables at the end of the --help.
(AC_ARG_VAR): Emphasize use of environment variables to override
and/or help the configure script. Ensure that a given variable
is only documented once in the --help.
(AC_CHECK_LIB): Call AC_ARG_VAR to document and register the
LDFLAGS variable, and...
(AC_CHECK_HEADER): do the same for the CPPFLAGS variable.
* aclang.m4 (AC_PROG_CC): Call AC_ARG_VAR to document and register
the CC and CFLAGS variables, and do the same for...
(AC_PROG_CXX): CXX and CXXFLAGS, and...
(AC_PROG_F77): F77 and FFLAGS.
variables as argument.
* acgeneral.m4 (_AC_LIBOBJ): Same as the former AC_LIBOBJ, but
takes an additional argument: action to perform when non-literal
argument.
(AC_LIBOBJ): Use it.
(AC_REPLACE_FUNCS): Use _AC_LIBOBJ, not AC_LIBOBJ.
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.
`aclocal.m4' and that of the location Autoconf extensions.
(-M, --m4dir): New option.
(aclocal_flags): Do not use $localdir, but $m4dir.
(localdir_opt): Remove, since $autoconf, $autoheader already
include `-l $localdir'.
* autoreconf.sh: Don't run automake when the package is not using
it.
When checking whether autoheader should be rerun, don't ask
config.h to be newer than stamp-h and vice-versa.
Remove an unbalanced `fi'.
(alflags.sed): New sub sed program.
Compute the flags of aclocal from Makefile.am instead of
Makefile.in, it is unlikely that aclocal be used but not automake,
while it is convenient to be able to run autoreconf even if
automake was not run yet.
Use `autoconf --trace' to get the list of configuration headers.
* tests/base.m4 (m4_wrap, AC_REQUIRE, AC_SHELL_MKDIR_P): Use it.
* autoconf.sh: Properly handle the case where `$output' is `-'
(i.e., stdout).
Handle `-ofile', not only `-o file'.
