The builtin prototype takes an `unsigned char `as the second argument.
`'\1'` is used in the valid case to match the exact type.
`2` and `-1` are used intentionally to test the **constant range check (0–1)**;
they are constant expressions implicitly convertible to unsigned char, which is
sufficient to trigger the intended diagnostic.
