Hi Mark, Thanks for the patch. I first did patch -p0 instead of patch -p1 and the version of patch in Debian Squeeze (testing) surprised me by saying that every hunk failed, and creating an empty b/src/... directory with .orig and .rej files.
The good news is that this should now no longer falsely complain about a flare road being the wrong direction when that flare road pair are the only roads connected to a given roundabout. Right, with the same map data, I get no warning for that roundabout.
The bad news is that it will now find more bad flare roads than it did before - and you thought you had fixed them all!
The good news for me is that I only saw 3 new warnings for Finland. :-) All were legitimate, and I fixed them already. In other words, please commit the patch. Marko
