* lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.

Browse Source 
(AC_C_RESTRICT): Likewise.  Furthermore, add a function with a
typedef'ed restricted pointer, to catch a compiler bug on
HP-UX 11.x, and fix warnings so it passes with -Werror.
(_AC_PROG_CC_C99): Likewise.
Reported by Albert Chin <china@thewrittenword.com>.
* tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.
