As the possible values are -2^31 - 2^31-1 there no ambiguity (if you're aware of that a negative value != -1 is really a big positive one). But I'm not against any improvements as that result might confuse people. How does the type offset_t fit into the ways of addressing the problem (if you know)? Right, MartinS
