Group,
I was talking about Turbo C floating point <emulation> context
switching, which is not very expensive from what I understand.
Dealing with a real mathco is another animal altogether.

Problem is it

I see. Does anyone have any code for auto-detection of an

Admittedly ELKS probably doesn't need FP, but my MicroWindows main
demo
does have a 3d graphics demo that requires floating point, it'd still
be nice to run it ;-)
