Compiling qemu on gcc4 has been a long standing issue. During the time
several approaches came up, each more or less intrusive.
I have collected the ones I found to be the cleanest, fixed PowerPC host
support with Michael Matz and am sending everything as a patchset now,
hoping that someone comments on these patches and they will finally get
included.
Please test these patches on all platforms you have available.
Regards,
Alex

Thanks but ppc target doesn't work here with gcc 4.3 trunk , i686-linux :
gcc -mtune=native -march=native -O2 -pipe -fomit-frame-pointer -Wstrict-overflow -Wall -O2 -g -fno-strict-aliasing -fomit-frame-pointer -I. -I..

Does not happen for me, with gcc 4.1.2 on OpenSUSE 10.2.

I guess so. Maybe I will find some time next week to compile gcc 4.3 and
test with it...

This looks rather like an old version of the patch. Are you sure you
did a ./configure after applying the newest version of the patch (the
one that modifies the configure script)?
