Thanks, I think it was CW6.

Thanks for the info, I'm confused though: the current version already uses:

+      std::map<int, std::ptrdiff_t, std::less<int> >::iterator pos =

Or have you got your diff the wrong way round, and did you mean that a
change to:

-      std::map<int, int, std::less<int> >::iterator pos =

was required, if so, what's the issue with std::ptrdiff_t?
