--- Comment #6 from Andrzej Krzemienski <akrzemi1 at gmail dot com> --- (In reply to Andrzej Krzemienski from comment #2) > No. Other compilers (Clang and VS 2010) do not emit such warning either. Correction: The newest version of Clang does give a warning: "definition of implicit copy constructor for 'W' is deprecated because it has a user-declared destructor [-Wdeprecated]"
