There are also problems on many X86 platforms, where one usually has to set
a compiler flag in order to get IEEE compatibile code out of the compilers.
I'm pretty sure the Windows version is not compliant. Don't know about the

Point taken. I'll b&m about any numerical software that doesn't at least make
the attempt to be IEEE compliant, or at least consistant across platforms.
