Do we really want to warn about the case where the class has no/trivial 
destructor?

+                 bool abstract = false;
+                 for (x = TYPE_METHODS (type); x; x = DECL_CHAIN (x))
+                   if (DECL_PURE_VIRTUAL_P (x))
+                     {
+                       abstract = true;
+                       break;
+                     }
+                 if (abstract)

Just check CLASSTYPE_PURE_VIRTUALS.
