Hi Denis!

I have found out that issue too, several months ago. It seems those functions 
are not used, at least in the EPIC kernel. Anyway, I have already commited a 
patch (use std::ptrdiff_t instead of long) for that in CGAL repository, and 
that should be fixed in CGAL-3.6-beta1 (already published) and CGAL-3.6 (that 
will probably be published during the week-end or on Monday).
