Halleluja. It still leaves us with all other compilers unaccounted for, 
but yes, this will allow fixing the problem for us in the future.

Too bad the current gcc-3.3 is apparently not useful for the kernel for
other reasons right now (ie the inlining issue which is being discussed on
the gcc lists, and that annoying sign warning), but that may well be 
resolved by the time it gets released.
