On x86_64-apple-darwin13 which doesn't show these failures, I see...

#define GNULIB_AREADLINKAT 1
#define GNULIB_TEST_LINKAT 1
#define GNULIB_TEST_READLINKAT 1
#define GNULIB_TEST_SYMLINKAT 1
#define GNULIB_TEST_UNLINKAT 1
/* #undef HAVE_LINKAT */
/* #undef HAVE_READLINKAT */
/* #undef HAVE_SYMLINKAT */
/* #undef HAVE_UNLINKAT */
/* #undef LINKAT_TRAILING_SLASH_BUG */
#define LINK_FOLLOWS_SYMLINKS 1

whereas on x86_64-apple-darwin14, I get...

#define GNULIB_AREADLINKAT 1
#define GNULIB_TEST_LINKAT 1
#define GNULIB_TEST_READLINKAT 1
#define GNULIB_TEST_SYMLINKAT 1
#define GNULIB_TEST_UNLINKAT 1
#define HAVE_LINKAT 1
#define HAVE_READLINKAT 1
#define HAVE_SYMLINKAT 1
#define HAVE_UNLINKAT 1
/* #undef LINKAT_TRAILING_SLASH_BUG */
#define LINK_FOLLOWS_SYMLINKS 1

Both filesystems are

Unfortunately, with this patch, I still see the failures on x86_64-apple-darwin14.

link-deref.sh: set-up failure: 
ERROR: tests/cp/link-deref.sh
FAIL: tests/cp/link-no-deref.sh
FAIL: tests/cp/link-symlink.sh
hard-to-sym.sh: set-up failure: 
ERROR: tests/ln/hard-to-sym.sh

Do we need to handle darwin14 differently now that it sets...

#define HAVE_LINKAT 1
#define HAVE_READLINKAT 1
#define HAVE_SYMLINKAT 1
#define HAVE_UNLINKAT 1

which was never tested on darwin before?
