VMS Help CC, Messages, ELLIPSEARG  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        Standard C does not permit the use of an ellipsis as
                an only argument.

 Description    Standard C requires at least one formal parameter be
                declared before the ellipses.  This declaration might
                not be portable to other C compilers.

 User Action    Recode the function declaration to contain at least
                one formal parameter.
