Uh, I thought pg_hypot() was still needed on our oldest supported
platforms.  Or is hypot() already supported there?  If not, I suppose we
can keep the HYPOT() macro, and have it use hypot() on platforms that
have it and pg_hypot elsewhere?  That particular fraction of 0001 seemed
a bit dubious to me, as the largest possible source of platform
dependency issues.
