I have just finished cross-compilation of MICO (http://www.mico.org) and
try small demo which failed with:

So, indeed, there are still some issues. :-)

Anyway, overall impression from QEMU is very good, I just hope that I will
be able to use it for our MICO related testing for x-linux (where x !=
x86) platforms -- I plan to do some testing of a bit larger C++ app for
you, if you are interested.
