drag and drop support status

[Richard M. Stallman]

In man/dired.texi:

    @cindex drag and drop, Dired
      On the X window system, Emacs supports the ``drag and drop''
    protocol.

And in man/files.texi:

      Secondly, Emacs supports the ``drag and drop'' protocol on the X
    window system.  Dropping a file into an ordinary Emacs window visits
    the file using that window.  However, dropping a file into a window
    displaying a Dired buffer moves or copies the file into the displayed
    directory.  For details, see @ref{Drag and Drop}, @ref{Misc Dired
    Features}.

Does this now work on MS Windows and MacOS?
