| * The solution is two-fold: |
| * 1. append {op_chars}* to xcstart so that it matches as much text as |
| * {operator} would. Then the tie-breaker (first matching rule of same |
| * length) ensures xcstart wins. We put back the extra stuff with yyless() |
| * in case it contains a star-slash that should terminate the comment. |
| * 2. In the operator rule, check for slash-star within the operator, and |
