I know, but I think it is still valuable a warning for -Wall because it *does* 
help many people. The few of us who can abuse C++ correctly at will can 
specify -Wnon-virtual-dtor and be done with it.

I still think that following Gaby's suggestion so to improve the warning to 
emit it on delete expressions is our best bet.
