* doc/autoconf.texi (Runtime) <AC_RUN_IFELSE>: Make synopsis show
that the default is configure failure. Rework the text about
proper use of the fourth argument.

* 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.
