Is there anyone who wants to look at this?

The functions file-attributes and directory-files-and-attributes both report
the link count as 1 for a file that has a link count of 2.  Hence ls-lisp
displays the wrong link count, whereas Cygwin ls displays the correct link
count.  The current release of Emacs (installed as a binary package and not
built by me) on Windows XP Home shows exactly the same behaviour.  In both
cases the files in question were on an NTFS partition.

I believe that at one time the link count was shown correctly, but I don't
know when it changed.  I suspect it's a generic problem on the Windows NT
platform line.

I think Eli already replied.  The "links" in this case are not
a feature of the filesystem, they are layered on top by Cygwin, so
only tools that link with the Cygwin libraries recognize them.
