 Message        <Context> an invalid redeclaration of "<name>" to or
                from a function type is being ignored.

 Description    In certain modes, the compiler will allow an
                identifier to be redeclared with a different type.
                In this case, the type of the redeclaration is used.
                However, in cases where the identifier is redeclared
                to or from a function type, the redeclaration is
                ignored.

 User Action    Remove the redeclaration of the identifier.
