I also don't really see this ever happening because the libstdc++ headers
aren't clean w.r.t. -Weffc++ (if you propose to turn those on too).  Even
the man page warns about it.  (Vast majority seem to be "non-virtual
destructor in base class" nonsense from my previous attempts.)  Even if
fine-grain, source-annotated warning suppressions (__attribute__, etc.)
kick in, *some* of the extra warnings would be a nuisance to work-around,
and extra work for library maintainers.  FWIW, -W -Wall has served me
quite well.  (-W is -Wextra since 3.4)
