It's nice to see somebody digging in that scary math emu stuff. If you could also get rid of the warnings, it would be perfect :-) Now, appart from that, I seem to remember Dan telling me at some point in the past (I think it was Dan... ) that this code was lifted from somewhere else (glibc ? gcc soft-float ?), in which case it might be worth to fix that somewhere else as well, or if it's already been fixed, maybe resync.
