--- Comment #8 from Rein Klazes wijn@online.nl 2009-05-03 08:12:41 --- The patch is a modification of the wine source. If you want to use it you must compile wine yourself in the first place.
Alternatively you have to wait until the patch makes into the official released wine. When that happens the bug will be closed and you are notified.
