    Don't include atime when determining hardlink compatibility.

    Don't include the atimes since we're comparing two paths stat()ed at
    different times, and depending on the
    platform/filesystem/mount-options, that may result in two different
    atimes, even when the paths refer to the same file.

    Thanks to Alexander Barton <alex@barton.de> for tracking down the
    problem.
