2) I am currently just trying to get the gapexe.386 port running.
However since I am putting it on a 486 I wonder:
I assume that gapexe.386 was compiled with 387 emmulation.
Is this correct?
If so, how much 'speed improvement'/'program size savings' is achieved
by compiling for a 387?

The DOS extender detects the presence or otherwise of a 387 at
run-time and looks for a software emulator only if one is needed.

In any event, I don't believe that GAP uses any floating point at
all.
