--- Comment #26 from Zebediah Figura z.figura12@gmail.com --- The commit was presumably migrated from CVS. The commit message is mostly the same as 9e49a9d43361fd1b08407a7efd4b6ae0e8f60825 still in the codeweavers git tree.
The patch was added to wine-staging in August 2014 by Sebastian Lackner. Given Dmitry's de facto status as a member of the Staging team, I would have thought that its presence in wine-staging was endorsed by the author. Of course, perhaps that has changed now that wine-staging has changed maintainership and project goals. Regardless of legal rights, the patch has been nonfunctional and disabled in Staging for some time, and so I believe the wine-staging maintainers would not object to removing the patch in any case, if the author wishes it.
The patch does not represent the correct way to solve the bug, in any case. The collation tables are generated and thus should not be manually edited. Fabian Maurer had been working on a patch set, which was last I heard incomplete, that solved the problem in a more correct way. I have not heard news from Fabian in several months, however.
