Ah, looking back on the discussion, I see the comments about 
cross compilation and soft floats. Making more sense now...

So if compiling on x86 for x86, you could just use hard floats, 
but if compiling on x86 for some other system, then use soft 
floats to mimic what the result would be as if you had compiled 
on that system. Correct?

But what if you are compiling for a system whose float behavior 
matches the system you're compiling on? So for instance, suppose 
you are only using 32bit floats and not allowing anything fancy 
like 80bit intermediate calculations. And you're compiling for a 
system that treats floats the same way. Then, you could 
theoretically use hard floats in the compiler and the results 
would be the same.
