+       getcwd: break fdopendir + save_cwd recursive loop (Bug#13516)
+       Reported for OS X 10.8.2 by Assaf Gordon in
+       <http://bugs.gnu.org/13516>.
+       * lib/getcwd.c (HAVE_OPENAT_SUPPORT): Do not define if
+       !HAVE_OPENAT && !HAVE_FDOPENDIR.
+       * m4/getcwd-abort-bug.m4: Reformat to match test-getcwd.c
+       so that they can be kept in sync more easily.  Avoid PATH_MAX
+       test on the Hurd.  Sync from test-getcwd.c for errno tests after
+       mkdir or chdir failure.
+       * tests/test-getcwd.c (HAVE_OPENAT_SUPPORT): New macro, from
+       lib/getcwd.c.
+       (test_abort_bug): Do not test for the deep directory bug unless we
+       have openat support.  Avoid PATH_MAX test on the Hurd.

        * tests/test-regex.c: Don't include regex.h twice.  Include
        string.h, to declare memset.  Christensen's report also mentioned
