What headers are available?  Do you have <limits.h>, say?  Even a
freestanding C compiler is supposed to have <limits.h>, <stdarg.h>,
and <stddef.h>.

I suppose we could change the check to look for <limits.h> if __STDC__
is defined, and for <assert.h> otherwise.  Could you write up a little
patch to do that, and see whether it works in your environment.
