This patch fixes two issues related to ctor/dtor warnings:

1. -Wctor-dtor-privacy often gives false positives.  Remove it from -Wall. 
   This was done in upstream for 3.4.  Note I have not updated the manpage
   with this patch.

2. -Wnon-virtual-dtor gives false positives when the dtor is declared
   private and no friend classes are declared.  This is acknowledged by
   upstream and will presumedly be patched very shortly (but I don't know
   which branch(es) will get this fix).  See GCC PR 15214.
