c++/689: [2003-05-03] [diagnostic] this warning is not helpful: `class xxxx' only defines a private destructor and has no friend

Jeff --

  I can't tell you how helpful or unhelpul that warning is.
However, g++ does provide an option to turn it on and off

    -Wctor-dtor-privacy
    -Wno-ctor-dtor-privacy

Maybe turning this warning on only if -Wextra is specified might be less
restrictive than the current situation.  I'm going to reclassify this
PR.

Thanks,
