C++0x FDIS 12.8/9:
If the definition of a class X does not explicitly declare a move constructor,
one will be implicitly declared as defaulted if and only if
— X does not have a user-declared copy constructor,
— X does not have a user-declared copy assignment operator,
— X does not have a user-declared move assignment operator,
— X does not have a user-declared destructor, and
— the move constructor would not be implicitly defined as deleted.
An explicitly defaulted copy constructor is user-declared, so a move
constructor is not implicitly declared.
