Do you have any examples of how GCC is *not* strictfp compliant (at 
least on common platforms)? My understanding is that, by default, it 
tries to be strictly IEEE 754. On x86 it will store values to memory and 
make a function call to do FP arithmetic, unless -ffast-math is given 
which allows it to do inline math using (the 80-bit x87) FP registers.

So, unless I misunderstand something and there is more to it, we should 
make -ffast-math the default for Java except where strictfp is encountered.
