When you are comparing gcc 4.2 to current trunk, are you keeping the
linker (binutils) version the same?  As mentioned in comment 6, the
linker behavior changed recently which results in a different default
alignment of the .bss segment which could explain the difference.

IMHO, we should just have gcc automatically enable -fno-common on PE if
SSE is enabled.  That's what the MS tools do, AFAICT.
