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

 Message        <Context> the promoted type of <name> is incompatible
                with the type of the corresponding parameter in a
                prior declaration.

 Description    The promoted interger or floating type of a parameter
                of an old-style function declaration does not match
                the integer or floating type given earlier in a
                prototype declaration of the function.

 User Action    Correct the data types so they match.  Compaq also
                recommends that old-style function definitions be
                replaced by prototype-format definitions.
