Semi-related: given an expression which is an integer constant, convert it to a statically-allocated char array. With appropriate sigils this can be extracted via `strings(1)`, even when cross-compiling. If you don't know what type of integer your preprocessor is using for arithmetic, you can still do right-shifts by up to 14 at a time, since `int` must be at least 16 bits and you can't use the sign bit.
