A fix (perhaps not the best, but it works) for underflows on the HP is
just to "use the force".  HP-UX obeys SVIDArith, so just setting that
switch in System/HP solves the pnorm problem.
(Thanks to Ross for pointing out the obvious underflow problem---I
wasn't thinking).

Here is my current System/HP file. --Mike
