I confirm that it works fine:

  * On NetBSD 7.0, configure finds that
      checking whether rename manages hard links correctly... yes
    and so REPLACE_RENAME = 0 and REPLACE_RENAMEAT = 0.
    And the rename/renameat tests pass.

  * On Cygwin 1.5.25, configure find that
      checking whether rename manages hard links correctly... no
    (because the test program exited with code 8),
    and so REPLACE_RENAME = 1 and HAVE_RENAMEAT = 0.
    And the rename/renameat tests pass.

But the test program does not call stat(), nor does it test st_nlink.
Still confused...
