Re: Unicode support for the MS Windows clipboard [new patch]

[Tak Ota <Takaaki.Ota@am.sony.com>]

I have confirmed both mingw build and MSVC build work fine in copying
and pasting unicode characters back and forth between emacs and
windoze application.  If there is no issues about this patch could
someone check it into CVS please.  Thanks.
