c4dbe5c591 Have --host=sun4 automatically look for CC=sun4-cc etc.
* acgeneral.m4 (AC_CHECK_TOOLS): New.
* aclang.m4 (AC_PROG_CXX, AC_PROG_CC, AC_PROG_F77): Use new
AC_CHECK_TOOLS macro instead of AC_CHECK_PROGS so that a cross
compiler is found by default with --host.
* doc/autoconf.texi (Generic Programs, Manual Configuration):
Describe new AC_CHECK_TOOLS macro. Fix unclear working about
AC_CHECK_PROGS.
* tests/Makefile.am (FILTER_MACROS): Adjust.

AC_LANG_FUNC_LINK_TRY(C++)): New macros.
(AC_CHECK_FUNC): Use it, together with AC_LINK_ELSE.
2000-05-24 14:22:39 +00:00

0705110354 The options --build etc. used to set `$build'. *If*
AC_CANONICAL_SYSTEM was run, then the value of `$build' given by
the user was saved into `$build_alias', and `$build' was
normalized using `config.sub'.

Now, let `--build' set `$build_alias' so that scripts with or
without `AC_CANONICAL_BUILD' have the same semantics.  This allows
to use `AC_CHECK_TOOL' without requiring `config.guess' and
`config.sub' (which was bizarre anyway).

* acgeneral.m4 (_AC_INIT_PARSE_ARGS): --build, --host and --target
set `build_alias' etc.
After the option handling, set host to $host_alias etc. for
bugward compatibility.
(AC_CANONICALIZE): Mutate into...
(_AC_CANONICAL_SPLIT): this, which does not canonicalize, it just
computes `$foo_os' etc.
(_AC_CANONICAL_THING): Remove, too confusing.
(AC_CANONICAL_BUILD): Adjust.
Do not assign any value to `build_alias', just compute `build', and
`build_{cpy, vendor, os}'.
(AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Likewise.
(AC_CHECK_TOOL_PREFIX): Fire your rule when `$host_alias' is
given, not when `$host != $build'.

* acgeneral.m4 (sinclude): Fix typo.

* aclang.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_F77): Call them.
(AC_PROG_CC_G, AC_PROG_CXX_G, AC_PROG_F77_G): Rename as...

Adjust dependencies.
* tests/Makefile.am (FILTER_MACROS): Adjust.
* doc/autoconf.texi (Compilers and Preprocessors): New section,
move the documentation of AC_PROG_CC, AC_PROG_CC_C_O,
AC_PROG_CC_STDC, AC_PROG_CPP, AC_PROG_CXX, AC_PROG_CXXCPP,
AC_PROG_F77, AC_PROG_F77_C_O, AC_PROG_GCC_TRADITIONAL here.
Factor the comment documentation of AC_PROG_CC, AC_PROG_CXX,
AC_PROG_F77.

ede91cff94 Modernize AC_EXEEXT and AC_OBJEXT.
Now work with other languages than C and C++.

AC_COMPILE_IFELSE/AC_LINK_IFELSE and AC_LANG_PROGRAM instead of
ad hoc code.
Use `$ac_ext' instead of listing `.c', `.C' etc.
Use AC_CACHE_CHECK.

bbd3b7f40c Load the additions *before* running AC_INIT.
This is important if you want to redefine AC_INIT or some of its
sub macros (eeerk!), or if you want to use user defined macros
before AC_INIT.
Suggested by Didier Verna.

* acgeneral.m4 (_AC_INIT): Don't include `acsite.m4' and
`aclocal.m4'.
* autoconf.sh (run_m4, run_m4f): Do it.
