I don't think these warnings are bogus. Mkgmap definitely has problems with multipolygons. The Languedoc-Roussillon extract (southern France) from Geofabrik provokes about a hundred of these warnings. But I believe that the intersected ways are being generated by mkgmap and that the OSM data is OK.
That is what I meant by "bogus": the input data is correct, and mkgmap is doing something wrong. The browse URL that I posted was for a block house in Helsinki, nowhere near my tile boundaries.

Marko, I tried to reproduce your problem but I wasn't able to. I downloaded the geofabrik dump of finnland of today and run splitter on it with the default settings. Then I started mkgmap (current trunk version) and no warning for the multipolygon 5828 was issued. Here is the log for the processing of mp 5828. 2010/01/26 18:46:45 FEIN (MultiPolygonRelation): Construct multipolygon http://www.openstreetmap.org/browse/relation/5828 2010/01/26 18:46:45 FEIN (MultiPolygonRelation): outer http://www.openstreetmap.org/browse/way/22467513 2010/01/26 18:46:45 FEIN (MultiPolygonRelation): inner http://www.openstreetmap.org/browse/way/22467516 2010/01/26 18:46:45 INFO (MultiPolygonRelation): Processing multipolygon http://www.openstreetmap.org/browse/relation/5828 2010/01/26 18:46:45 FEIN (MultiPolygonRelation): Joined 4611686018427388656 with 22467513 2010/01/26 18:46:45 FEIN (MultiPolygonRelation): Joined 4611686018427388657 with 22467516 2010/01/26 18:46:45 FEIN (MultiPolygonRelation): createContainsMatrix listSize: 2 2010/01/26 18:46:45 FEIN (MultiPolygonRelation): check polygon 0 2010/01/26 18:46:45 FEIN (MultiPolygonRelation): check polygon 1 2010/01/26 18:46:45 FEIN (MultiPolygonRelation): createMatrix for 2 polygons took 0 ms 2010/01/26 18:46:45 FEIN (MultiPolygonRelation): Containsmatrix 2010/01/26 18:46:45 FEIN (MultiPolygonRelation): {1} 2010/01/26 18:46:45 FEIN (MultiPolygonRelation): {} WanMil
