I agree on both points. I think the only thing that's saved us is that
most gnulib-using projects already ask for C99 compatibility if available,
for the usual reasons.

I don't think the autoconf patch would be that easy, as one would
need to handle a mixture of AC_PROG_CC_C99, AC_PROG_CC_C89, and
AC_PROG_CC_STDC calls. Again, I expect the only thing that's
saved us is that people just use AC_PROG_CC_STDC. Hmm, maybe
Autoconf should deprecate the other two macros?
