Adjust to the moving target called the C++ standard.
Apparently nowadays it's not allowed to define an explicit copy
constructor but not an assignment operator. Consequently, defining the
explicit copy constructor in terms of the implicit/automatic
assignment operator for general convenience no longer works.
Add assignment operators.
Caution: not tested with the IBM compiler, but there's no particular
reason it shouldn't work.
