I used different solution. The <boost/cstdint.hpp> header sets up #defines so "(unsigned) long long" support and "(unsigned) __int64" support are mutually exclusive. I did the same.

Works for me (tested with both VC 7.1 and 8.0). Thanks a lot! Cheers, Ralf ____________________________________________________________________________________ Want to start your own business? Learn how on Yahoo! Small Business. http://smallbusiness.yahoo.com/r-index
