 Message        Syntax error in constant expression.

 Description    A preprocessing constant expression contained a
                syntax error.  The preprocessor was expecting to find
                a constant value or a left parenthesis.  The
                preprocessor will assume a value of zero was
                encountered.

 User Action    Correct the preprocessing constant expression.
