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.
