Hi Marko, just to make sure: The example shows a no_u_turn restriction where "from" way and "to" way are equal and a via node is used.
Are that the criteria which should tell mkgmap to emit an info and ignore the restriction? Why not a warning? I'd say all correct restriction relations which are ignored should produce a warning.
