Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Here is an example, this bug seems only on ms-windows:
(let ((tmp (make-temp-file "link-test"))
(link (make-temp-name "link")))
(make-symbolic-link tmp link t) ; here is ok
;; error occur, the third argument should suppress the error
(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. What error message did you see from the second
call?
Maybe your Windows user doesn't have the necessary privileges or
something? 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? What happens if you insert
(sleep-for 10) between the two calls to make-symbolic-link?

Thank you for your help.
The error is `file-error "Making symbolic link" "Operation not permitted"`
When i run as administrator, it is solved.

OK, so I'm quite sure this is an issue with your user's privileges.
If you have enough control of this system, you should be able to
modify your privileges to add symlink creation. I forget how I did
that, but you will find enough recipes on the Internet.

Ok thanks, completely solved the problem.
Because I was able to make symbolic link for the first time, I didn't expect the privilege issue. :)
