&gt; 
&gt; Here is an example, this bug seems only on ms-windows:
&gt; 
&gt; (let ((tmp (make-temp-file "link-test"))
&gt;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; (link (make-temp-name "link")))
&gt; &nbsp; (make-symbolic-link tmp link t) ; here is ok
&gt; &nbsp; ;; error occur, the third argument should suppress the error
&gt; &nbsp; (make-symbolic-link tmp link t))

I cannot reproduce this, your example works for me as expected on
MS-Windows (same version as you are using), and creates the symlink
without any errors.&nbsp; What error message did you see from the second
call?

Maybe your Windows user doesn't have the necessary privileges or
something?&nbsp; What happens if you run Emacs from a cmd.exe window that
was started by "Run as Administrator"?

Or maybe your filesystem on which you do this is something strange.
is that a local disk formatted as NTFS?&nbsp; What happens if you insert
(sleep-for 10) between the two calls to make-symbolic-link?
