 Message        <Context> a parameter declaration cannot include an
                initializer.

 Description    The parameter declaration list of an old-style
                function definition included an initializer.  This is
                not valid.

 User Action    Remove the initializer from the declaration and
                initialize the parameter in the function body.
                Compaq also recommends that old-style function
                definitions be replaced by prototype-format
                definitions.
