Actually, I was still looking at this issue, but I am concerned by the
interface.  We should deprecate AC_PROG_FOOC for looking for FOO
compilers.  One issue is that the interface is pretty bad, and does
not allow cleanly to specify the list of compilers, nor what should be
done IF-HAVE, and IF-HAVE-NOT.

2.58 is really needed, so I propose that we keep this code in 2.58,
but do not document it yet: that will make the test suite exercise
this code.  But we should still address once for all the *generic*
interface for AC_LANG_COMPILER, and stop new AC_PROG_FOOC.  This can
be done in 2.59, and I will pay extra attention to devote enough time
to this.
