+            Clearer warning message for badly constructed typecheck typemaps. For example, was:
+
+              example.i:3: Warning 467: Overloaded foo(int) not supported (no type checking
+              rule for 'int').
+
+            Now:
+
+              example.i:3: Warning 467: Overloaded foo(int) not supported (incomplete type checking
+              rule - no precedence level in typecheck typemap for 'int').
