------- Comment #7 from thomas dot mcguire at gmx dot net 2008-08-21 18:43 ------- Just want to add my support for this feature.
I had quite some bugs which I would have discovered earlier if this warning here was implemented. In particular, in KDE4/Qt4, lots of virtual functions were removed or changed, and the code using was never adjusted properly, and now just silently fails. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17920
