>Description:
	There is another typo in fts(3); fts_open takes a pointer to
	function which returns not pointer to int but just int.

	In fts(3), there is a description like this:

     FTS *
     fts_open(char * const *path_argv, int options,
             int *compar(const FTSENT **, const FTSENT **))

	Because function call operator () has high priority than dereference
	operator *, it means that `compar' is a function which returns
	pointer to int (and the value fts_open is passed is a pointer to it).

	But in /usr/include/fts.h, fts_open is prototyped like this:

FTS	*fts_open __P((char * const *, int,
	    int (*)(const FTSENT **, const FTSENT **)));

	It says that third argument is a pointer to function which returns int.

>How-To-Repeat:
	Type man fts and read it.  Then, read /usr/include/fts.h or
	/usr/src/lib/libc/gen/fts.c.
>Fix:
	Give parentheses around `*compar'.
