| # The test below just wants to know if flex can process multiple |
| # concatenated options. The -c and -n options both do nothing, so we |
| # group them together to see if flex will still function. We write the |
| # output to /dev/null since we don't really care what flex produces, |
| # just that it runs successfully. |
