    Fix comment so that /* does not appear inside a comment.
    
    The block comment in m2.flex associated with splitSlashStar
    contains /* which causes a warning.  This patch obfuscates
    the comment /* symbols.
    
            * m2.flex (splitSlashStar): Fix comment so that /* does not
            appear inside the comment.
