+       openat: test for fstatat (AT_FDCWD, ..., 0) bug
+       This tests for another fstatat bug on AIX 7.1:
+       fstatat (AT_FDCWD, ..., 0) does not work.  See
+       <http://lists.gnu.org/archive/html/bug-tar/2011-09/msg00015.html>.
+       * lib/fstatat.c (FSTATAT_AT_FDCWD_0_BROKEN)
+       (LSTAT_FOLLOWS_SLASHED_SYMLINK): Default to 0.
+       (rpl_fstatat): Adjust so that it works around either (or both)
+       bugs if present.
+       * m4/openat.m4 (gl_FUNC_FSTATAT): Test for this fstatat bug.
