Sure. 

template<typename Reference>
struct referent_storage {
  typedef typename remove_cv<typename 
remove_reference<Reference>::type>::type referent;

  BOOST_STATIC_CONSTANT(std::size_t, target = 
referent_alignment<Reference>::value);

  typedef typename type_with_alignment<target>::type align_t;

  typedef aligned_storage<align_t,referent_size<Reference>::value> type; 
};
