 Message        Strict standard C extension:  The declaration of the
                "main" function has more than two parameters.

 Description    Standard C requires that the "main" function takes no
                more than two parameters.  Compaq C will accept more,
                but the program does not conform to the C standard.

 User Action    Modify the declaration if you want the program to be
                standard conformant.
