as far as i know, all plan 9 compilers use IEEE 754-compatable semantics
(at least insomuch as allowed by hardware).  thus the minima and maxima,
ε, and underflow properties depend on IEEE 754, not the processor.

/sys/doc/port.ps has the most complete information, but i would imagine
that the powerpc and arm information is slightly out-of-date.
