Pacify -Werror in two places
Although this cannot easily be done in general, there are a couple
of places where it’s easy.
* lib/autoconf/c.m4 (AC_LANG_INT_SAVE (C)):
Change ‘()’ to ‘(void)’ to pacify picky compilers.
Problem reported by Vincent Lefevre in:
https://lists.gnu.org/r/autoconf-patches/2020-08/msg00000.html
(AC_C_INLINE): Likewise.
