It seems like the coprocessor emulators and libraries don't work with 
signals.  This small program doesn't get SIGFPE when run under either
emu387 or wmemu387:

main()
{
  float f = 0.0;
  f = 1.0 / f;
}

Of course no one would do this is practice, but the FSU pthreads library
uses signal handling and it doesn't seem to work at all
with floating point emulation.  So it might be related to the above.

Does anybody know what's going on?
