 Message        There is no declaration for the old-style function
                parameter "<name>".  Type defaulted to int.  This is
                a violation of the C99 standard.

 Description    The parameter of an old-style function definition was
                not declared.  It will default to int type.  Omitting
                the type specifier is not valid in C99, and is often
                considered poor programming practice.

 User Action    Declare the parameter.  Compaq also recommends that
                old-style function definitions be replaced by
                prototype-format definitions.
