Yes, it is. Unfortunately, it's also wrong. If you have a pointer to
char but need to treat the data it points to as unsigned char, you have
to cast the pointer and dereference it to get the correct value on ones
complement systems -- dereferencing and then casting doesn't work
because -0 gets converted to +0.
