To me too...
Perhaps a private optimization of the Linux folks on their compiler (but it 
is strange it is the same on a lot of Linux distro, like debian, rh ...)
OpenBSD 3.1 (gcc version 2.95.3 20010125 (prerelease)) acts like FreeBSD.
Perhaps you should know if NetBSD is like the other *BSD or it is in the 
other way.

Thanks Warner for your tips ... I'll forward immediately to developers team 
of the emulator to see if we can arrange a viable solutions of this problem.

Thanks very much again.
