I remember asking this question a long time ago - in the context of
"What will happen if I run a DJGPP compiled program that does floating
point on a 486 DX, but happen to have the emu field set in the GO32 var?"

At that time, I was told (by who I cannot remember) that it would use
the chip (i.e., would "do the right thing").  Was I misled?
