You can customize the native converters by providing a specialization of
luabind::default_converter<>. See:

  test/test_user_defined_converter.cpp

Something like:

  namespace luabind {

  template <>
  struct default_converter<__int64>
    : native_converter_base<__int64>
  {
      static int compute_score(lua_State* L, int index)
      {
          return default_converter<int>::compute_score(L, index);
      }

      __int64 from(lua_State* L, int index)
      {
          return (__int64)lua_tonumber(L, index);
      }

      void to(lua_State* L, __int64 value)
      {
          lua_pushnumber(L, value);
      }
  };

  } // namespace luabind

Should do it.
