Hi!
Why does QEMU (versions 0.9.1 and 0.10.5 tested) "support" the "Pentium
II Math Bug" from 1997?

Maybe because nobody knows. I have only briefly looked into the code
and I believe it wasn't intentional and is just some side-effect of
the implementation. In fact I believe more of the FPU flags are not
reported correctly.

I wish QEMU having a bug tracking system, e.g., Bugzilla, Trac, or
Mantis, used by many / all people.
