+  <li>A new command-line option <code>-Wdelete-non-virtual-dtor</code>
+      has been added to warn when <code>delete</code> is used to destroy
+      an instance of a class which has virtual functions and non-virtual
+      destructor. It is unsafe to delete an instance of a derived class
+      through a pointer to a base class if the base class does not have a
+      virtual destructor.  This warning is enabled by <code>-Wall</code>.
