bug#37203: 26.2; error on load with .emacs.d symlink on windows

I want  to store my init.el on Google drive so it shares between computers.
So I created a windows symlink:
mklink .emacs.d Google\emacs
I do this as administrator, because you have to on windows.

I get the following error when using runemacs.exe
--------------
Warning (initialization): Unable to access `user-emacs-directory'
(~/.emacs.d/).
Any data that would normally be written there may be lost!
If you never want to see this message again,
customize the variable `user-emacs-directory-warning'.

--------------
Not sure what is going on here, but this is my guess:

It is mistakenly thinking that the directory isn't writable probably
because it is a <SYMLINK> rather than a <DIR>, or alternatively because the
symlink is owned by Administrators.

This doesn't create a directory symlink, it creates a symlink to a
(non-existent) file.  To make a directory symlink, you need to do this
instead:

  mklink /d .emacs.d Google\emacs

If this doesn't work either, please tell more about what does "Google"
above represent, as it doesn't seem to point to a drive, at least not
syntactically.

If ownership winds up to be the problem (I don't think so), it can be
changed from the Windows Explorer or other similar tools.

Ahh, ok thanks. Although the link did seem to work for m-x load-file

In any case, i found that mklink /j also seems to work. Some different kind
of link i dont fully understand.

So does this mean this issue can be closed?
