I was a little ambiguous. I meant that statement in general, but I in the
particular case of floating-point, being fundamental, probably should work
as now defined,
and I didn't think NaNs satisfied the last bit of being stupid, ill-advised
or impossible.

Looking at the code generated, I'd have thought that it was the use of FCOM
instead of FUCOM that mattered,
not the integer unit comparison that's subsequently used.
