Description
Hi, I am not able to build qemu successfully on my gentoo box with gcc 3.4.6.
Heres the build error

Yup, am on a 32 bit machine, AMD Athlon 2000+ XP to be exact

It is confirmed by upstream: gentoo's 3.4.6 doesn't build qemu on 32-bit x86. A
gcc developer (Paul Brook) said gentoo's gcc "is broken" and nothing can be done
outside gentoo.
I myself use gcc-3.3.6 which for some reason was the default when I installed
gentoo.
Hmm, I'm not having this error although I'm on gentoo as well. It may have
something to do with 32-bit register set, are you on a 32-bit system? I can
only test on 64-bit but I would expect someone in upstream tests things on
32-bit (as this bug would be an upstream bug)
