Added the warning code

Browse source 
WARN_PARSE_REDUNDANT          322

similar to the g++ -Wredundant-decls flag.

This recovers the warnings that now are not been reported by
the original code

   WARN_PARSE_REDEFINED          302

Redundant example:

   int foo(int);
   int foo(int);

Redefined example:

   int foo(int);
   double foo(int);
