//  MACRO:         BOOST_NO_USING_TEMPLATE
//  TITLE:         using template declarations
//  DESCRIPTION:   The compiler will not accept a using declaration
//                 that imports a class or function template
//                 into a named namespace.  Probably Borland/MSVC6 specific.

template <class T>
int global_foo(T)
{
   return 0;
}

template <class T, class U = void>
struct op
{
   friend op<T,U> operator +(const op&, const op&)
   {
      return op();
   };
};

using ::global_foo;

   boost_no_using_template::op<int, int> b;
