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.
