+ openat: port to AIX 7.1 with large files
+ AIX 7.1 does a "#define openat open64at" if large files are in use,
+ so we can't simply #undef openat. Use the orig_openat trick (similar
+ to orig_open in lib/open.c) to work around the problem. Problem
+ reported by Kevin Brott for GNU tar, in the thread containing
+ <http://lists.gnu.org/archive/html/bug-tar/2011-09/msg00032.html>.
+ * lib/openat.c (__need_system_fcntl_h): Define first.
+ Include <fcntl.h> and <sys/types.h> before undefining.
+ (orig_openat) [HAVE_OPENAT]: New inline function.
+ (openat) [HAVE_OPENAT]: Do not undef.
+ (rpl_openat): Use orig_openat, not openat.

+ openat: test for fstatat (..., 0) bug
+ Further testing with tar suggests that fstatat (..., 0)
+ does not work in general, on AIX 7.1; see
+ <http://lists.gnu.org/archive/html/bug-tar/2011-09/msg00023.html>.
+ So, give up entirely on AIX 7.1's fstatat, and fall back on our
+ replacement fstatat (which is what older AIX releases were using
+ anyway).
+ * lib/fstatat.c (fstatat) [HAVE_FSTATAT]: Do not undef. The only
+ use is now changed to orig_fstatat. This was probably the right
+ thing to do anyway.
+ (FSTATAT_AT_FDCWD_0_BROKEN): Remove; no longer used.
+ (rpl_fstatat) [FSTATAT_ZERO_FLAG_BROKEN]: Remove.
+ (rpl_fstatat): Simplify, assuming !FSTATAT_ZERO_FLAG_BROKEN.
+ (AT_FUNC_NAME) [FSTATAT_ZERO_FLAG_BROKEN]: Now rpl_fstatat.
+ * m4/openat.m4 (gl_FUNC_FSTATAT): Test for the more-general bug
+ and define FSTATAT_ZERO_FLAG_BROKEN, not FSTATAT_AT_FDCWD_0_BROKEN,
+ if the bug is found.

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
