Geeze, UTSL folks! :-)

                        if (*tty == '\0' || best != 0) {
                                if (best == 0)
                                        status = PERMISSION_DENIED;
                                /* no particular tty was requested */
                                (void) strcpy(ftty + sizeof(_PATH_DEV) - 1,
                                    line);
                                if (stat(ftty, &statb) == 0) {
                                        if (!(statb.st_mode & 020))
                                                continue;
                                        if (statb.st_atime > best) {
                                                best = statb.st_atime;
                                                (void) strcpy(tty, line);
                                                status = SUCCESS;
                                                continue;
                                        }
                                }
                        }

Looking at the loop in question, you can see that it tries to pick a
"best" tty now rather than simply settling for the first one that's
applicable.  The checks for applicability, e.g. whether or not the
modes are correct and the tty is openable, remain unchanged.
