NWFPE or FastFPE?
We've already seen FastFPE as a cause of 0 == 0 not working.
But a -DDEBUGGING perl working fine when a "normal" perl does not is odd.
["normal" is a bit of an arbitrary term. I'm smoke testing 5.8 on x86 FreeBSD,
and I think I managed 192 distinct configurations without the benefit of
long doubles]
I've no idea if the known FastFPE problem has been distilled to a C code
example, or whether the author of FastFPE is aware of it.

PS perl 5.8.0 RC1 is out. If you are able to spare the time,
please break it.
