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.
