The fix is below (add to integer_traits.hpp): {{{ #if defined(BOOST_HAS_MS_INT64) && !defined(_MSC_EXTENSIONS) template<> class integer_traits< __int64 > : public std::numeric_limits< __int64 >, public detail::integer_traits_base< __int64, _I64_MIN , _I64_MAX> { }; #endif }}} ",Bugs,closed,Boost 1.40.0,integer,Boost 1.39.0,Showstopper,fixed,,
