/* When fts_read returns FTS_DC to indicate a directory cycle,

it may or may not indicate a real problem. When a program like

chgrp performs a recursive traversal that requires traversing

symbolic links, it is *not* a problem. However, when invoked

with "-P -R", it deserves a warning. The fts_options member

records the options that control this aspect of fts's behavior,

so test that. */
