 Message        <Context> the number of parameters differs from an
                earlier declaration of this function.

 Description    A function has been redeclared with a different
                number of parameters than a previous declaration of
                the function.  This message generally proceeds
                additional errors.

 User Action    Correct the function declarations so that the
                parameter information is the same in each
                declaration.
