The GCC Upgrade Guide (http://www.gentoo.org/doc/en/gcc-upgrading.xml) doesn't mention that you cannot build a 2.4 kernel with GCC 4. This would be a good warning to those of us still stuck on 2.4 for a while. Might also be good to have some information about being able to slot GCC 3.x and GCC 4, and the necessary precautions with compiling modules (see #8 on bug 145819 for what I mean).

Once you rebuild your world with new GCC, external modules (like app-emulation/qemu-softmmu) will fail to load. Please rebuild your kernel with the new GCC to fix that."
Fixed in CVS, thanks for your time.
