/* Test warnings and errors for incomplete parameter types.  Should
   not be warned for in declarations that are not definitions: bug
   17881.  Void types may be a special case, especially for unnamed
   parameters and when qualified or with a storage class specifier;
   see C90 6.5.4.3, DR#017 Q14, C90 TC1, DR#157, C99 J.2 (referencing
   C99 6.7.5.3); the precise rules are unclear.  */
