Without casting, a warning could be triggered on 64 bit systems, because on these systems a signed 64 bit int (off_t) is compared with an unsigned 64 bit int (size_t) which could never be larger. Casting it to uintmax_t, which is at least 64 bits in size, silences this error. No technical reason beyond that.
