 Message        <Context> <name> is not a parameter.

 Description    The identifier name in the parameter declaration does
                not match a name in the identifier list of an
                old-style function definition.

 User Action    Correct either the identifier in the declaration or
                in the identifier list so that they match.  Compaq
                also recommends that old-style function definitions
                be replaced by prototype-format definitions.
