I don't include <sys/types.h>. The standard says I shouldn't have
to. But autoconf is about the real world as much as it is about standards...
I don't use caches. See previous thread on this mailing list
"config.cache considered harmful".
I think checking for size_t as well as int is useful, since they may
indeed be different sizes, which will affect correctness, as well as
compilation warnings.
Obviously, both our examples need improvement to be incorporated into
autoconf. I'll leave that to the hard-working autoconf maintainers.
