 Message        Trailing comma found in enumerator list.

 Description    Accepting an enumerator list that contains a trailing
                comma is an extension of Compaq C provided for
                compatibility with other C compilers.  An enumerator
                list with a trailing comma is not valid in C89, nor
                in C++.  The C99 standard does permit this syntax.

 User Action    Remove the trailing comma.
