When comparing signed with unsigned types, the signed values are first converted to unsigned, then possibly zero-extended. So (unsigned)-1 == (int)-1 but (unsigned long)-1 == (long)-1 only when sizeof(long)==size(int) > and please note that also sizeof(int) == sizeof(unsigned int), but > -1 is a signed int !! So?
Stupid me.. OK is == -1 and not < 0.. Probably today I'm drunk without drink .. Enjoy - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
