Not yet, but nearly! :-)
The following patch for the Wine port finally allows this PR to be fully
closed. (The kernel has already been updated, but neither the Wine port
nor this PR have been...)
Please install the patch below and remove files/patch-3.3-sys-fsgs from
the Wine port and also from pkg/PLIST of that port.
Approved by the maintainer of that port. (Myself ;-) )
