There it is, my take on Boost.Ptr_container:

This passes the testsuite just like vanilla develop when compiled with
 * msvc 9.0 which has no std::unique_ptr
 * msvc 14.x in a mode without std::auto_ptr
 * msvc 12.0 which has both std::auto_ptr and std::unique_ptr

The std::auto_ptr-based library interface can be deliberately disabled,
and similarly the std::auto_ptr-based tests.

I'm all ears for suggestions, pointing out errors, whatever ...
