(_AC_FUNC_VFORK): this.
Remove AC_DEFINEs and don't guess cross-compilation values.
(_AC_FUNC_FORK): New, check whether fork() isn't just a stub.
(AC_FUNC_FORK): New, use _AC_FUNC_VFORK and _AC_FUNC_FORK to
define HAVE_WORKING_FORK, HAVE_WORKING_VFORK; and vfork to fork if
vfork doesn't work.
Guess values if cross-compiling, but warn.
* acfunctions: Add AC_FUNC_FORK.
* doc/autoconf.texi: Document AC_FUNC_FORK. Give example to define
and vfork appropriately.
Reported by Derek R. Price.
* tests/semantics.at (AC_REPLACE_FUNCS): New test.
* acfunctions.m4 (AC_REPLACE_FUNCS, _AC_LIBOBJ_ALLOCA): Use
AC_LIBSOURCES.
AC_OUTPUT_MAKE_DEFS to include junky -D switches.
Reported by Wolfgang Mueller.
* tests/torture.at (#define header templates): Include trash in
confdefs.h.
* tests/atgeneral.at (AT_INIT): Don't expect `find' to support
-maxdepth, hence don't use -follow either.
Reported by Nicolas Joly.
* acgeneral.m4 (AC_OUTPUT_MAKE_DEFS) <confdef2opt.sed>: In the
`quote' section, `p'rint the result.
If neither `#define' pattern match, just call `d' to start a new
cycle.
Call this sed program with -n.
* doc/autoconf.texi (Limitations of Usual Tools) <expr>: More
information, thanks to Paul Berrevoets, Paul Eggert and David
Morgan.
* sh.m4 (_AS_EXPR_PREPARE): New.
(AS_DIRNAME): Use it.
the new macro...
Reported by Ezra Peisach.
* tests/semantics.m4 (AC_HAVE_FUNCS): New test.
* tests/tools.at (autoupdate): As a benign side effect, updating a
macro that takes no argument produces `UPDATED([])', no longer
`UPDATED()'. Adjust the test.
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).

because it produces TEST3; TEST2a; TEST2b; TEST1.
Fix this bug, implement the solution provided by Axel Thimm,
and test AC_REQUIRE.
* acgeneral.m4: Document this implementation.
(_AC_DEFUN_PRO, _AC_DEFUN_EPI, AC_REQUIRE): Be sure that macros
are emitted in the same order as they are expanded.
(AC_REQUIRE): Forbid being calling out of an AC_DEFUN'd macro (in
particular the top level).
* tests/base.m4 (AC_REQUIRE): New test.

Reported by Alec Wolman.
* acspecific.m4 (AC_FUNC_GETLOADAVG): Check for `getloadavg'
without any additional library.
Fixes Autoconf/109.
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.

Document --help=short and recursive.
Split the `Directory' section into `Installation directories' for
--prefix and --exec-prefix, and all the others into `Fine tuning
of the installation directories'.
In the latter, don't repeat `in DIR', the user understands, and it
comes out better.
Default for --exec-prefix is PREFIX.
Reported by Kathryn Hargreaves.
Move --host before --build.
Fix a test on `$ac_init_help' which was not updated.

AC_OUTPUT over quotes too: stop that.
Reported by Martin Buchholz.
* doc/autoconf.texi (Output): Don't expand on the ternary
AC_OUTPUT.
* acgeneral.m4 (AC_OUTPUT): Don't over quote $2 and $3.
headers if they exist (needed for some missing prototypes) and
corrects the signal handler prototype/definition. The signal
handler prototype is now prepended with an `extern "C"' for C++
compilers since some platforms explicitly require an `extern "C"'
signal handler.
