There are a few platforms, the most prominent of which is alpha, on
which GCC offers an option to enable or disable strict IEEE
compliance.  On alpha, it's -mieee.  Even x86 has -mieee-fp, to handle
unordered compares correctly in all cases.

Oh, wait.  You were talking specifically about Java.

I'm not sure going all the way to -ffast-math would be appropriate,
but certainly disabling strict IEEE compliance by default, on
platforms on which it makes a difference, would be perfectly
reasonable.
