Preprocessor macro for -mfpmath=sse ?


Hi,

I have implemented some interval arithmetic code which has to work around the
well known non-compliance (IEEE 754) issues of x86's floating point unit.
I would like to get rid of these costly workarounds when I compile with
-mfpmath=sse.
Would you consider adding a preprocessor macro that I could test for ?
