I think dropping gcc 3.x support for 64-bit kernel is not what we wanted. And -msym32 is just an optimization and kernel should be buildable without it. So "remove -msym32 silently" is not so bad, I suppose. "If you used newer compiler, you can get better result" is natural thing, isn't it? ;) --- Atsushi Nemoto
