 Message        <Context> the declaration of the function "<name>"
                containing no parameter information replaces an
                earlier declaration of "<name>" at <location>.

 Description    A function which was previously declared with a
                function prototype has been redeclared without
                parameter information.  This is a violation of the C
                standard.  The Compaq C compiler will accept this for
                compatibility with older compilers.

 User Action    Remove one of the declarations.
