[ntl] NTL RR class and long long integer

[Victor Shoup]

A followup: "long long" is only a part of the language standard
since C++11.  So I guess before C++11, there was no standard
way to get at 64-bit integers on Windoze. Anyway, now that it is 
a part of the standard, it would be reasonable to contemplate
making such conversion operators.  But they would only be useful
for Windoze platforms, and that is a low priority.
Plus, one would have to provide legacy switches so that
one could get rid of these on platforms that have not yet
implemented the C++11 standard.
