+       utimens (fdutimens): ignore a negative FD, per contract
+       * lib/utimens.c (fdutimens) [HAVE_FUTIMENS]: Call futimens only
+       when we have a valid file descriptor.  Otherwise, using a brand
+       new glibc (with just-patched futimens that now fails with EBADF)
+       would cause this function to fail with ENOSYS.
+       Reported by Guillaume Ayoub in http://bugs.debian.org/563726.
+       See also http://bugzilla.redhat.com/552320.
