I've noticed that ptr_container/clone_allocator.hpp contains an undocumented 
overload of new_clone that accepts a pointer-to-const:

template< class T >
inline T* new_clone( const T* r );

It is annoying because it doesn't support a pointer-to-non-const argument, 
resulting in a compile error if you try.  Any chance one of the following 
could be done?

1) remove it

2) add a pointer-to-non-const overload

3) change it to
template< class T >
T* new_clone( T* r );

4) or if you care about always returning a pointer-to-non-const change it to
template< class T >
typename remove_const<T>::type * new_clone( T* r );
