That's one part. The other one is the detection (and replacement) of
the 'ret' in emulated functions. There, gcc-4 optimizes things so that
the 'ret' happens in the middle of the function followed by some less
probable (but required) branches.

My comment was not a complain about gcc4, just a question how qemu can
be built with gcc4... ;)
