This change is imported from gnulib.
* lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Don't bother compiling
or running anything if c99, or if unsigned long long int does not
work. In either case, we know the answer without further tests.
Do not compile _AC_TYPE_LONG_LONG_SNIPPET twice. Instead, compile
it at most once, and use its results for both long long int and
unsigned long long int. This is more likely to be efficient in
the common case where the program wants to check for both long
long int and unsigned long long int.
(AC_TYPE_UNSIGNED_LONG_LONG_INT): Don't bother compiling if c99,
since the answer is already known.
* NEWS: Document this.
* doc/autoconf.texi (Particular Headers): Likewise.
In example, don't assume a 'system.h' exists.
* lib/autoconf/headers.m4 (AC_CHECK_HEADER_STDBOOL): New macro.
Use it with AN_IDENTIFIER, since it's less heavyweight.
Reindent to match gnulib, since that's a bit nicer.
(AC_HEADER_STDBOOL): Reimplement in terms of it.
* doc/autoconf.texi (Parallel Make): Document that some make
implementations, when run in parallel mode, connect stdout and
stderr of child processes to pipes or temporary files, and might
re-route stderr of spawned processes to stout. Also document
that FreeBSD make in parallel mode reuses the same shell for
multiple commands within one recipe (like NetBSD make does).
* doc/autoconf.texi (Timestamps and Make): Document HP-UX 11.31
make issue with targets having the same time stamps as their
prerequisites.
* doc/install.texi (Particular Systems): Warn against using
HP-UX make.

(AC_FC_DUMMY_MAIN usage, AC_F77_MAIN usage, AC_FC_MAIN usage):
