 Indeed, but it also seems that the patch hasn't yet made it to a source
 tarball. Nor is it clear what exactly the patch is, the author mentions
 "another patch" a few months after someone posted one.

 we don't move to Bison 3.

 Fair enough, but for those ports it'd be nice if Bison 2 remained
 available, so that their maintainers can tweak their build system to use
 that version.
