That's about representation of integers types. Pointer types are another matter. C99 sections 6.2.5 and 6.2.6 cover this. This is all just academic language lawyering, of course. Any machine on which a pointer isn't NULL after being memset to 0 has serious quality of implementation issues. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
