[mkgmap-dev] Patch for routing problems in r2448 and higher

Mon Feb 4 10:40:49 GMT 2013

Is remove_short_arcs v4.patch also needed?

Because the Fix Routing_patch_v1
doesn't fully solve it for me. Now I can route along that previously 
broken stretch of road. But I still cannot route from it to another 
road. Or route from it to somewhere else.

Also there seems to be a huge bug about relations now. They appear all 
over the place now!
So beware, this patch is not suitable for productive use!
