Hi,
there were compilation errors when I was trying to compile i386-softmmu
target on i386
host (running on Fedora-13 with development version of qemu downloaded
from git).
There were errors of comparison of unsigned expression was always true
which made it
unable to compile. This simple fix fixes the issue.
