PROMOTMATCH

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

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

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