I see your point. The question is: what happens if we forcibly cast a 8 byte unsigned long into a 4 byte (unsigned ...) int.
One point is only sun related here: the 1/2TByte limit for sun partitions. The other things are generic ones, independent of the architecture but no: at the very moment that a long differs in size from an int we run into problems IMHO. It's unclean, at last.
Do you think it would be better to do an explicit cast in each call to pinpoint the issue?
Thanks for your inputs, and, yes, it's been quiet on sparclinux, it sounds like Dave Miller is (hopefully!) off for holidays - and I think he deserves it, doesn't he :-) ?
Take care
Dieter
