I do not believe the C++ standard requires this.  Mark Mitchell
explained to me that g++ warns because g++ assumes copy constructors
that do not deal with a base class accidentally omit dealing with the
base class and the author should look into this.  Neither he nor I
know of a way to turn off these g++ warnings without turning off all
warnings.
