It's probably just an unsigned char -- 8 bits, with the possible range of 0-255. I suppose Aaron *could* have written it so that 0 was interpreted as 1, 255 as 256 (casting to a larger type), and so forth... but pretending that 0 means 1 is a very good way to lose sanity tracking down subtle bugs...
