Comment (by michel):

 Do we really need to detect the clang and libstdc++-4.2 configuration?

 What's the problem of always using Boost versions of `move`/`forward`
 {{{
 template <typename T>
 inline T&&
 forward(typename boost::remove_reference<T>::type& t) BOOST_NOEXCEPT
 {
     return static_cast<T&&>(t);
 }

 template <typename T>
 inline T&&
 forward(typename boost::remove_reference<T>::type&& t) BOOST_NOEXCEPT
 {
     BOOST_STATIC_ASSERT(!boost::is_lvalue_reference<T>::value);
     return static_cast<T&&>(t);
 }

 template <typename T>
 inline typename boost::remove_reference<T>::type&&
 move(T&& t) BOOST_NOEXCEPT
 {
     return static_cast<typename boost::remove_reference<T>::type&&>(t);
 }
 }}}
 ?
