Anyone know where I could get the source code for doing 64-bit integer arithmetic - the long longs? Or anyone have it and could mail it to me? I need to be able to do both signed and unsigned 64-bit integer arithmetic on a compiler that doesn't support it. The fix is to use two 32-bit integers (which I presume is what GNU does). My attempts at doing this have failed, but if I could find some source code for doing it... Thanks Adam
