`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'.
* 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.
in a messy state. Don't even try to emulate AC_REQUIRE: just
introduce a diversion just for AC_REVISION, and let the magic
happen.
Fixes Autoconf PR/134, from Raja R Harinath.
* acgeneral.m4 (_AC_DIVERT(REVISION)): New diversion.
(AC_REVISION): Don't require AC_INIT, dump in your diversion.
(_AC_INIT): Delete, inline its body in...
(AC_INIT): here.
(_AC_INIT_NOTICE, _AC_INIT_COPYRIGHT): New macros so that...
(AC_INIT): be more uniform.
(AC_INIT, AC_REVISION, AC_COPYRIGHT): `define', don't AC_DEFUN.
compiler needs it, it is likely to be required when linking C/C++
with Fortran.
<-YP,*>: Fix the list of arguments to loop on.
Don't mess with the user variable name space.
<ac_ld_run_path>: Prepend LD_RUN_PATH directories with -R only
when running Solaris (without this, link errors occur).
warning message printed when only --host is given. Fix printing
of multiple compiler cache values, use PATH argument.
* aclang.m4 (AC_LANG_COMPILER_WORKS): Print the cross compile
status, fix problem where two results were printed at once.
lf95 (Lahey/Fujitsu Fortran) and pgf77 (Portland Group Fortran)
(_AC_PROG_F77_G): Some Fortran compilers produce stdout/stderr
output even if no errors occur - check exit status rather than
output.
* 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.
