I found, in the FreeBSD ports collection (where I became maintainer of
the Wine port which I'm plan to ``minimize''), the following patch which
is superflous as far as can see.
Am I missing something obvious here, or is this just a historic relict?
(Originally that patch was much larger, but I changes in Wine essentially
made those parts obsolete, so I removed them with my first update for the
port.)
