Would it be possible to write a NEW mathffp.library that was really a sort of ieeemath.library (or whatever its name is) in disguise. That way, if you have a program that opens the ffp library, uses a lot of trig, and is slow, you could substitute the new ffp library, and be fast. Usual disclaimer. I dunno nuthin'
