Message        <Context> function types differ because one has no
                argument information and the other has an ellipsis.

 Description    Two function types, used in an operation or a
                redeclaration of a function, are different because
                one uses ellipses and the other does not.  Older
                compilers will accept this, but it is not valid
                standard C.

 User Action    If used in an operation, a cast should be inserted.
                If used in a redeclaration, the redeclaration should
                be removed or modified.
