Comment (by joseph.thomson@…):

 Assuming that boost::move_detail::is_copy_constructible and
 boost::move_detail::is_copy_assignable work on VC++ (if the tests pass, it
 would seem this is the case), I still don't know if this change fixes the
 bug.  The is_memtransfer_copy_constructible and
 is_memtransfer_copy_assignable functions, as far as I can tell, perform
 the same function as is_trivially_copy_constructible and
 is_trivially_copy_assignable, but they still have incorrect
 implementations which rely only on boost::has_trivial_copy and
 boost::has_trivial_assign.  Surely you need to change the implementation
 of these functions to fix the problem?
