Also, what about detecting a coprocessor so that your code can choose
between an emulator and a real copro? That way floating point math'll work
on any machine, but the speed advantage will be there if it runs on a
system with a real coprocessor. Or is that done automatically by go32 or
whatever if you include an emulator?
