SubjectRe: Compiling kernel with SuSE 8.2/gcc 3.3
Although it fixes it for building on 32 bit architectures, won't changing



generate a type mismatch warning on ppc64 and similar 64 bit
architecutres since __u64 is not a unsigned long long on ppc64
(it is unsigned long)? My gut reaction is to just ingore the three
places that cause warnings and the remaining two places that cause
signed/unsigned compare warnings of unsigned int local variables
to #defined literals (which presumably are treated as signed by default).
