Subject: [boost] [smart_ptr] make_shared perfect forwarding bug

Perfect forwarding doesn't seem to work quite correctly with
boost::make_shared. The attached program, which tries to pass a move-only
type through make_shared fails to compile with gcc in c++0x mode. To fix
it, I had to change the definition of detail::forward in make_shared.hpp
to use rvalue references:
#if defined( BOOST_HAS_RVALUE_REFS )
template< class T > T&& forward( T &&t )
{
return t;
}
#endif
This is just based on looking at how gcc implements std::forward. Is this
the right fix?
