There is no error in your test case; hence the compiler should not
report anything.

It is a perfectly legal C++ technique to declare, but not define
member functions. An example:

  class Base { ...
  protected:
       Base(const Base &);           // not implemented
       Base &operator=(const Base&); // not implemented
  };

The idea here is that instances of the Base class should not
be copied. The author of Base guarantees that if someone writes
Derived class which inherits from Base, they would not be able to
copy the Base part of Derived. If they do, they'll get an error at
link time.
