[lib/ChangeLog]
* fcntl_.h (O_NOFOLLOW): Don't depend on O_NOFOLLOW_IS_INEFFECTIVE;
we now test for that separately.
* fts.c (fts_safe_changedir): Inspect HAVE_WORKING_O_NOFOLLOW
rather than O_NOFOLLOW, when testing whether it's possible to
avoid a race condition reliably.
* savewd.c (savewd_chdir): Likewise.
[m4/ChangeLog]
* fcntl_h.m4 (gl_FCNTL_H): Define HAVE_WORKING_O_NOFOLLOW instead
of O_NOFOLLOW_IS_INEFFECTIVE.  Define HAVE_WORKING_O_NOATIME if
O_NOATIME works.
