[Qemu-devel] x86 FPU Emulation

[The Qube]

Using any DOS/DOS-like setup under qemu x86 (no kqemu/qvm86) and running 
calc387 will produce non-sane results.  For example, "calc387 2^4" produces 
17.7635.  "calc387 4^2" produces 17.7635 as well.  I've verified this is not 
an issue with calc387 by  running the above two calculations under dosbox 
0.63 with the dynamic core and geting "16" back for both..  I've test this 
on an Athlon XP system.  runcom doesn't work with calc387, so qemu-i386 
isn't testable.
