The old implementation didn't work either.
It failed completely for denormal numbers for which the target
format also used a 15-bit exponent, i.e 80-bit double-extended
and 128-bit quad precisions.

When I checked in the code, I had a 100% success for Paranoia
on x86, sparc, and alpha. I've not checked since then since
I'd not changed the arithmetic routines at all. I'll re-check.
