Subject: FileUtils.ln cross platform?

What happens when you use FileUtils.ln on a Windows system. Does it
fail? Is that why Jim Weirich uses #safe_ln, eg.

  LINKING_SUPPORTED = [true]

  # Attempt to do a normal file link, but fall back
  # to a copy if the link fails.
  def safe_ln(*args)
    unless LINKING_SUPPORTED[0]
      cp(*args)
    else
      begin
        ln(*args)
      rescue Errno::EOPNOTSUPP
        LINKING_SUPPORTED[0] = false
        cp(*args)
      end
    end
  end

If so, is there a better way? Or why wouldn't this be built into Ruby.

Thanks,
T.
