Don't forget that if you compile with -fsoft you lose the advantage of 
hardware floating point. You still have to compile two different versions if
you want hardware floating point, depending on the machine you expect to run on.
Also, a program compiled to produce inline '881 on a Sun 3 with the FPU
WON'T run on a Sun 3 without the FPU.
I thought what we were looking for was a method to allow running a program
with inline '881 code on a machine without an '881. I don't know who (if
anyone) has that ability, but Sun doesn't.
