[Mplayer-dev-eng] Re: Experimental patch for optimized "wine" build for mplayer

Hi,

A few day ago, I wrote:

Now I've found the first avi file (http://static.hugi.is/movies/405.avi ~8MB)
that works with the optimized and fixed wine loader,  and that crashes with the
unpatched mplayer-cvs of today:


                   ________________________________________


With today's cvs version, I get

% ./mplayer -ao null /tmp/405.avi

                   ________________________________________



I've placed an updated version of my wine/loader patch here:

  http://www.tools.de/solaris/mplayer/mplayer-wineopt-patch
  

Has anyone tested/played with the patch?  Did it break anything?
Any objections if I just check in this patch into the current CVS tree?
