--- Comment #3 from Francesco Munda syylk@hotmail.com 2008-04-29 03:29:58 --- As a temporary, case-by-case only fix, I attach the patch (in diff unified) that I'm using with my local portage overlay.
The patch should NOT be used unless strictly required: as explained by Stefan, it'd undo another needed fix.
Still, for people having my same problem, could be helpful.
Download WINE sources, unpack them, and from the source root dir, type:
$ patch -p1 </path/where/you/saved/my/patch
Appropriately substituting the actual filename+path of the attached patch.
