1) I believe that is to warn about a possible mistake where you really want -1 and not 0xFFFFFFFF.
2) It tells the compiler "shut the hell up, I know what I am doing, thank you" because the usage is correct in those places.
3) unsigned long
4) Setting an unsigned value to -1 appears to be a generic way to set a variable, be it 16, 32 or 64 bits wide, to its highest value/all bits set. Is this nonstandard C?
