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