In this case, there is no overflow. Subtracting 1 from 0xff is non-overflowing regardless of whether the type is signed or unsigned. If it is signed, the result is -2 (0xfe) And in both cases, the result is well within the bounds of an int. The difference is whether it gets sign-extended (signed char) or not (unsigned char).
