That was my thought also: let the variable be unsigned, and have it wrap around normally. So once you reach UINT_MAX, the next line number is zero (instead of getting stuck at UINT_MAX, which would be rather strange). Anyway I don't think anyone is going to reach the UINT_MAX limit ... I mean that would be one hell of a query, wouldn't it. If your query is upwards of a million lines, surely you are in deep trouble already.
