I don't think that's true. I asked a powerpc64 person about it the other day, and he said they don't use anything beyond the lower 32 bits. If people are really supposed to use unsigned long, it would make sense to get the i386 macros changed, since they are canonical. -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
