It's been slightly annoying but not too much of a pain to keep things working with gcc4, and using -Werror does mean that genuine warnings don't get lost in the noise. Anyway, we have more serious problems with gcc4 (I can't boot dom0 as far as a login prompt when I build xen+xenlinux with gcc4). Currently gcc 3.2.x and 3.3.x are the main supported compilers. -- Keir
