I think "no" and "yes" are being redefined as different types --
definiteAnswer and anyAnswer.

As for the type issue, you can use:
   typedef enum {noDefinite, yesDefinite} definiteAnswer;
   typedef enum {noAny,yesAny,maybeAny} anyAnswer;

if you want to be sure the enums become types.

Hope this helps.
